3 Fix segv in ZOOM_connection_fire_event_socket YAZ-858
4 The odr_in memory taken by handle_srw_response, and, thus if result
5 set is destructed before we expect the HTTP response (hres) it may
6 be come invalid. Therefore we inspect hres before the call to
9 Fix possible deadlock in backtrace (2nd attempt) YAZ-856
10 An alarm is set up so that backtrace is terminated if it hangs.
11 Even if backtrace the handler also attempts to spawn gdb.
15 Fix SEGV for s=sl for 3 terms and syntax error YAZ-857
19 Fix possible deadlock in backtrace YAZ-856
21 Various minor text tweaks in documentation
25 Fix yaz-client command args parsing broken YAZ-855

43 Omit Content-Type for HTTP requests to Solr YAZ-850
47 Fix rpn2cql: structure, relation problem for serverChoice YAZ-849
48 Problem was that for things mapped to cql.serverChoice the relation
49 would sometimes be omitted when it should not. Eg for relation "all".
53 Document zoom extraArgs YAZ-817
55 Fix ZOOM: crash extended services diagnostics YAZ-846
56 The immediate fix is to prevent ZOOM_set_dset_error from removing
57 current task from connection. This, however, has been assumed in a
58 number of places so this fix is rather large unfortunately.
62 Make yaz_log_reopen async-signal YAZ-845
63 Fixes potential dead-lock issue with YAZ_DAEMON_LOG_REOPEN flags for
68 CCL: new feature s=spl (split-list) that splits terms in a search into
69 sub-phrases of all sizes (from 1 up to the number of terms) with order
70 preserved. For 3 terms the CCL search
73 @or @or @or @and @and a b c @and "a b" c @and a "b c" "a b c"

103 Document itemorder-setname and list all ILL options
105 --- 5.11.0 2015/03/31
107 Extend get_org_info (snippets) to return original string YAZ-836
108 Two new functions have appeared: icu_chain_get_org_info2 and
109 icu_iter_get_org_info2 with a 4th parameter being a pointer
110 to the original string.
112 Fix tcpip.c compilation failure on VC9 YAZ-835
114 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
115 The icu_iter_get_org_info returns information based on string
116 as it appears on tokenize step.
118 --- 5.10.2 2015/03/13
120 Deal with excess bytes in HTTP response for keepalive YAZ-830
122 Refactor ssl_put and tcpip_put to one function YAZ-832

128 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
130 --- 5.10.1 2015/03/03
132 Fix test_sru.sh fails in pazpar2 YAZ-826
133 Unfortunately a regression occurred with YAZ 5.10.0 that would make
134 Pazpar2 fail for HTTP connections.
136 --- 5.10.0 2015/03/03
138 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
139 Introduce cs_create_host2 which returns if connection should be
140 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
141 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
143 Fix http proxy fails with yaz-client YAZ-824
147 Fix 0 ptr reference for OPAC records from XML YAZ-822
151 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
155 record conv: 'select' return org record if no x-path match YAZ-814
157 retrieval: pick matched element-set rule YAZ-813
159 Fix crash in record conv rule 'select' YAZ-812
163 record_conv: selection by X-Path YAZ-811
164 That's a new step in record conversion system (<select path=".."/>)
166 Document record render parameters for ZOOM - including base64
170 Fix application/x-www-form-urlencoded + empty YAZ-810
171 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
172 and empty content was supplied.
174 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
176 Fail hard if Bison is not found and is needed YAZ-808
180 Enable YAZ backtrace for programs YAZ-802
182 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
183 Libxml2 2.9.2, Libxslt 1.1.28.
185 Fix daemon: parent process stops before child YAZ-806
186 Try to fix the situation where parent process stops before
187 child has acknowledged it .. SIGUSR2 back!
189 daemon: log message when keepalive stops.
193 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
194 would make yaz-marcdump crash when from-character set was issued.
198 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
199 New function yaz_enable_panic_backtrace which enables backtrace
200 handler for current process. The handler will call backtrace always,
201 then gdb to provide as much detail as possible.
205 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
206 and ZOOM record render will inspect leader 9 and switch to UTF-8
207 (Unicode) if that holds 'a'. This changes behavior, but is considered
208 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
210 Fix cs_put may reconnect if send fails. YAZ-798
214 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
218 Extended comstack with outgoing IP YAZ-795.
219 For cs_create_host + cs_create_host_proxy the vhost may be followed
220 by a outgoing host/IP. Separator is blank.
224 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
225 linker error with yazpp on Windows.
229 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
231 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
233 0 ptr reference in handling Solr response with error YAZ-791
235 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
237 Fix documentation about --installa option YAZ-788
241 daemon: properly report when receiving SIGUSR2 from child YAZ-785
245 xmalloc: throw assert for clearly invalid calls to malloc and
246 improve diagnostics YAZ-783 YAZ-784
250 Stop building debs for Ubuntu raring, quantal, oneiric.
252 CCL YAZ-781: for multiple use attributes in a specification the
253 generated RPN will perform @or on each term.
254 For spec: term u=31 u=1016
255 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
257 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
259 CCL YAZ-779: combo qualifier should allow for forward references
261 Fix buildconf.sh, automake too old on centos5 YAZ-778
262 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
263 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
264 accepts it without a warning.
268 GFS: client_query_charset conversion YAZ-777
269 This is a feature for Z39.50 clients that sends queries that are not
270 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
271 encoding given to UTF-8.
273 Echoed SRU arguments support YAZ-776
274 This is achieved with new function yaz_srw_get_pdu_e.
276 ZOOM: expire times set for redis/memcached YAZ-772
277 For both redis and memcached option --expire=seconds sets expire
278 time for a result-set/search. Default time is 600 seconds (10 minutes).
282 No [rest of output is omitted] limit for yaz_log YAZ-774
284 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
286 For ICU testing, pass -o to yaz-icu. This will test the
287 icu_iter_get_org_info function.
289 Fix null ptr reference for freeReplyObject YAZ-773
293 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
295 RPM: do not build with libmemcached support. The libmemcached library
296 on CentOS 5/6 does not work reliably for us (redis to the rescue).
298 configure: only allow libmemcached version 0.40 or later. That's the version
299 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
300 that's not an option, consider redis.
304 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
306 Fix zoom+memcached: present request out of range YAZ-767
310 CCL: add new qualifier r=omiteq which will omit relation=equals
311 for ordered relations. This should be used in combination with either
314 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
316 Solr: simplify yaz_solr_decode_response
318 Solr: use different local var for string manipulation
320 Solr: Get rid of hardcoded limit of extra_args
322 Solr: encode lucene query type YAZ-736
323 Make sure the queries are treated as traditional "lucene", because that's
326 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
330 Build packages for Ubuntu Trusty Tahr 14.04 LTS
332 wrbuf_cstr: fix off by one error.
334 wrbuf_buf: make it always return non-NULL
335 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
339 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
341 zoomsh: offer option -a apdulog
342 As we're used to from yaz-client and GFS based servers.
344 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
345 existing setting apdulog takes effect.
347 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
352 Add re-entrant CQL/Solr/RPN query conversion functions.
353 The re-entrant functions are: cql_transform_r,
354 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
355 These have same functionality as cql_transform,
356 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
357 return the additional infomration as WRBUF to make them re-entrant.
359 Remove CQL to Solr conversion and base solr_transform_t on
360 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
361 data structure as cql_transform_t.
363 cql2pqf utility allows RPN to Solr conversion
365 Fix assert in ZOOM when http connect fails YAZ-757
367 --- 5.0.22 2014/04/09
369 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
371 wrbuf_cstr: make it thread safe YAZ-753
373 yaz_log_init_file may take fd=<no> to open log file at the FD given.
375 --- 5.0.21 2014/03/21
377 Offer new utility function zget_AttributeList_use_string.
379 New conversion step, solrmarc, for record conversion module.
381 --- 5.0.20 2014/03/13
383 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
384 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
387 --- 5.0.19 2014/03/10
389 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
390 The standalone ZOOM sort was completely broken since 5.0.13.
392 ZOOM: generate event Connect rather than None for partial connect
393 (in fact getaddrinfo resolving).
395 ZOOM: only supply clientIP for InitRequest. Rather than for all
398 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
400 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
401 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
402 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
404 New "Facets" section in the documentation.
406 --- 5.0.18 2014/02/27
408 Call exsltRegisterAll in yaz_init_globals, so that all applications
409 using YAZ will have EXSLT things enabled.
411 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
413 Update various URLs to the re-organized SRU pages at LoC.
415 --- 5.0.17 2014/02/26
417 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
418 introduced in 5.0.12.
420 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
421 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
422 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
425 --- 5.0.16 2014/02/25
427 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
429 --- 5.0.15 2014/02/24
431 Fix gcrypt not properly initialized YAZ-740.
433 --- 5.0.14 2014/02/19
435 Describe memcached option for ZOOM.
437 ZOOM: throw present request out of range again YAZ-739
438 Was removed in YAZ 5.0.13.
440 --- 5.0.13 2014/02/18
442 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
443 with localtime_r when threads + fork is used (such as Metaproxy).
445 yaz-config: quote some RHS values (that might include blanks)
447 zoomsh: shows SearchResult-1
449 zoomsh: sortby command
451 zoomsh: use proper list of connections and result sets YAZ-725
453 Avoid yaz_log in sigterm handler for GFS YAZ-737
454 Logging is still performed, but outside sig handler.
456 New ZOOM C feature: result-set caching with memcached. Example:
457 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
459 Remove SSL via OpenSSL support YAZ-732
460 Also deprecate two functions from comstack that aren't working with
461 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
463 Revert "Bison: use %name-prefix directive rather than -p option"
465 --- 5.0.12 2014/01/22
467 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
469 SRU GET/Solr base URLs may hold additional ?args YAZ-729
470 ZOOM option extraArgs already does this, though. It seems useful
471 when dealing with Solr targets to limit by filter, eg.
472 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
474 Remove #fragment for HTTP request encoding YAZ-730
476 Doc: Update list of DLLs/LIBs
478 Doc: update href link to Unix utils and Git.
480 --- 5.0.11 2014/01/15
482 ZOOM: fix "lost connection" problem with servers that uses both squid
483 and another proxy behind it that returns Location headers with relative
486 zoomsh: do not use readline for stdin (no tty) YAZ-724
487 Just use fgets in that case. If the user hits Ctrl-D a new-line
490 zoomsh: empty command ignored YAZ-723
491 rather than performing exit of zoomsh.
493 yaz-url utility offers option -v to enable verbose mode.
495 yaz_url uses yaz_check_location and offers verbose mode.
497 Add new function yaz_check_location.
498 This function gets an absolute URI from Location (HTTP redirect).
500 cookie API: introduce yaz_cookies_reset
502 Update cql.y for newer bison YAZ-720
503 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
504 longer supported. Instead one must use %lex-param and %parse-param .
506 --- 5.0.10 2014/01/09
508 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
511 rpn2solr: support truncation left(2), left&right(3) YAZ-718
513 Mention SRU version 2.0 in yaz-client man page.
517 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
522 Make cs_parse_host public.A
524 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
525 introduced in YAZ 5.0.6.
529 Fix buffer corruption for yaz-ztest record fetch.
533 Allow yaz-ztest to return user-defined records (one record per file).
534 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
536 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
537 Use the stream write instead of odr_printf which has a 4K tmp buffer.
539 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
543 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
544 can read and write this format. For record format JSON, yaz-ztest returns
545 MARC-in-JSON records.
547 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
548 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
552 Improve error reporting for ICU chains YAZ-707
553 Report config element+rule when ICU status is "failure".
555 ZOOM: stop fetching if present response has no records YAZ-710
556 Some targets return less records than their hit count would suggest.
557 This prevents ZOOM from continuing to fetch records if any present
558 response has 0 records in the response.
560 Ensure that GFS calls exit if any listener fails YAZ-710
561 Before, if XML config was in use, it would start the default
566 yaz-ztest: -V shows version (like yaz-client -V)
568 New iconv encoding: danmarc YAZ-692
570 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
572 daemon: only wait for immediate child rather than all children. YAZ-704
574 yaz-client: fix setting of SRU record schema. If scheme was unset, it
575 could lead to invalid memory reference.
579 yaz-ztest returns schema for MARCXML test records. SRU require that
580 recordSchema for records.
582 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
583 instead of non-surrogate diagnostic. This is a per-record failure.
585 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
586 may refer to multiple listeners now. Attribute listenref is a comma separated
589 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
590 option is given for GFS, the dirname of filename (for -f) is used
591 as prefix for options such as cql2rpn, ccl2rpn, etc.
593 Content-Type charset fixes YAZ-701 . Do not inspect charset in
594 Content-Type header for SOAP when decoding SRU. The payload (XML)
595 itself tells what encoding it is. In response, never supply encoding
596 in Content-Type. The response payload (XML) tells what it is (with no
597 encoding in XML it's UTF-8).
599 HTTP decoding: allow blanks in URL paths YAZ-700
603 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
604 and facets. Ensure recordData and recordSchema are always present in
605 record element, because they are required.
607 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
610 Simplify in a lot of places using odr_strdupn.
612 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
616 Increase various buffers in GFS's statserv_options_block
617 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
618 This change makes many type-casts redundant, and, thus simplifies code.
620 Remove last bits of WAIS support.
622 Remove member 'size' from Odr_oct.
624 Slim down the public part of 'struct odr'. Most elements are not part
625 of struct Odr_private.
627 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
628 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
629 In particular facets are supported in both client - and server side.
630 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
631 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
632 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
633 both request/response). This is what a search handler in the GFS
634 will see (regardless of whether operating in SRU mode or Z39.50).
636 Changes to the srw.h (SRU/Solr) definitions include:
637 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
638 (char*), which replace union query and query_type (int). This is because
639 SRU 2.0 supports a queryType parameter. This also means that, to carry
640 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
641 x-pquery=PQFstring (extention parameter). The extension parameter
643 - New element, packing, that has information about SRU
644 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
646 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
648 New element, packing, in Z_SRW_explainRequest.
650 New elements in Z_SRW_scanRequest, queryType and scanClause.
651 These replace query_type and scanClase untion. This is similar to what
654 --- 4.2.69 2013/10/01
656 GFS: log when closing down - at least SIGTERM YAZ-684
657 Also change formatting WRT PID logging a bit.
659 Improve display of MARC records with multi-byte subfield IDs YAZ-695
660 In some rare cases subfield identifiers are multi-byte characters.
661 This will try to deterime length of those and split accordingly.
662 This affects display in line mode as MARCXML/MarcXchange. The encoding
663 of ISO2709 is the same.
665 Change inp argument to const for yaz_read_UTF8_char.
667 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
669 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
671 Better check of marc leader info YAZ-691
672 Problem is that some systems generate MARCXML/MarcXchange with
673 funny headers. These will not work if encoded as ISO2709.
674 Some tests produce new output, due to updated warning messages
676 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
678 yaz-client: display MAB records YAZ-689.
679 Thanks for Heiko Jansen for this patch.
681 New utility z_get_HTTP_Response_server which allows both HTTP server name
682 and HTTP server URL to be given in response.
684 Debian: do not depend on obs tcl8.3.
686 Debian: do not depend on obs libicu36-dev.
688 --- 4.2.68 2013/09/23
690 GFS: pass additionalSearchInfo to search memeber search_input if
691 given. Otherwise pass otherInfo. Request for facets and other search
692 related things will be passed there in future versions of YAZ.
694 New ZOOM setting, authenticationMode, which allows authentication
695 paramters to be encoded in the URL rather than via HTTP Basic auth.
698 rpn2solr: fix nested AND/OR handling. YAZ-685
700 Add comparison routines for some Z-types, such as NamePlusRecord,
701 RPNQuery, Query, RecordComposition and OtherInformation.
703 --- 4.2.67 2013/09/19
705 Don't decode MAB as MARC. Just like we don't attempt to decode
706 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
708 CCL: allow quoted terms for date ranges. YAZ-681
710 Introduce ccl_parser_qual_search. This function makes old function
711 ccl_qual_search, from YAZ 2, available again.
713 Add yaz_facet_list_to_wrbuf. YAZ-683
715 --- 4.2.66 2013/09/11
717 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
718 schema was given for search. YAZ-675
720 Add Solr date range searches. YAZ-621
722 --- 4.2.65 2013/08/22
724 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
726 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
728 ISO2709/MARC parse most octet aligned records; not just those that
729 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
730 MARC parse more records instead of just dumping as is. YAZ-670
732 ZOOM: proper caching for variations of record schema. YAZ-671
734 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
736 --- 4.2.63 2013/07/17
740 --- 4.2.62 2013/07/11
742 New utility z_get_HTTP_Response_details - an extended version of
745 New utility yaz_url_get_error which returns error message of last
746 failed yaz_url_exec call.
748 yaz-url and url functions: allow max HTTP redirects to be controlled.
750 New functions yaz_file_glob2, yaz_xml_include_glob.
751 These functions takes a flags parameter, which, for now only controls
752 whether to fail inclusion of a non-existing file (without glob
753 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
755 --- 4.2.61 2013/06/20
757 For MARC XML parsing, allow record without leader. A fake/default leader
758 is inserted and a warning is tagged with the record.
760 ICU: fix leak in in icu_iter_get_org_info.
762 --- 4.2.60 2013/06/14
764 ICU: fix bug in icu_iter_get_org_info (un-init variable).
766 --- 4.2.59 2013/06/11
768 Implement z_HTTP_header_remove.
770 --- 4.2.58 2013/06/11
772 ICU: Disallow 0 ptrs for some ICU string utilities.
774 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
775 returns original tokens (before normalization).
777 CCL: avoid z39.58/regex truncation when not needed. Apply only the
778 conversion of those masks, when absolutely necessary.
780 CCL: configurable masking character - @mask. Default masking character
783 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
784 full response anyway, so a Transfer-Encoding header will obstruct the
787 --- 4.2.57 2013/05/15
789 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
790 picking a socket. Problem is that some systems has IPV6 support, but
791 we can't create sockets for them, so we pick AF_UNSPEC first.
793 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
794 use content_len to determine resulting Content-Length in HTTP response
795 and NOT Content-Length supplied in headers by user.
797 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
798 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
800 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
803 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
804 with big endian and unsigned char (by default).
806 --- 4.2.56 2013/04/26
808 Fix yaz-client connect (crash in 4.2.55).
810 --- 4.2.55 2013/04/26
812 Fix proxy/host problem for ZOOM that could occur if unix sockets
815 New Debian package libyaz4-dbg.
817 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
818 differently in tcpip_close.
820 --- 4.2.54 2013/04/17
822 Windows installer of YAZ includes YAZ4J as a component.
824 CQL: allow "extra terms" again, by default. Thus, the CQL parser
825 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
826 and earlier. CQL parser may operate in strict mode where queries
827 not conforming to the standard BNF are rejected (syntax error).
828 Whether the CQL parser operates in strict mode is controlled with
829 cql_parser_strict . Strict mode enabled with option -S for utilities
830 cql2pqf and cql2xcql .
832 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
834 --- 4.2.53 2013/04/10
836 New charset, MARC-8c, which is like MARC-8 but allows control characters
837 0x01 through 0x1F, except ESC to be passed through verbatim.
839 Fix a problem with duplicate sub field character in MARC output. Problem
840 happened only when output was MARC-8 encoded.
842 --- 4.2.52 2013/04/03
844 yaz-ztest: Use hash for fake hit count. Before, random number was used.
845 This is problematic for unit tests using yaz-ztest. This patch also makes
846 a hash for CQL queries. For RPN, any term with a leading digit will be
847 treated as pseudu hit count (to force any particular hit count by a client).
849 yaz-ztest: return unique MARC dummy records. Beyond record offset
850 24, the author surname is patched with offset to make all records
853 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
854 on system wide default (/proc/sys/net/ipv6/bindv6only).
855 @4 binds to IPV4 only. @6 binds to IPV6 only.
857 Update CQL API documentation a bit
859 CQL: don't accept extra terms for queries. Makes the CQL parser
860 stricly conformant to the standard.
862 --- 4.2.51 2013/02/12
864 GFS: scan handler gets extra_args from request and may return extra
865 response data . That's for SRU only.
867 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
869 --- 4.2.50 2013/01/30
871 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
873 OPACXML: sync spelling of availabilityDate in XML to that of Schema
874 opaxxml.xsd. The schema had the correct spelling of this member always.
875 The ASN.1 was mis-spelled and still is (API change) - we are
876 not changing this. However, the OPAC to XML conversion had yet
879 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
882 New function, z_ext_record_oid_nmem, which is similar to
883 z_ext_record_oid but takes NMEM rather than ODR
885 --- 4.2.49 2013/01/18
887 ICU: New conversion element 'join' which joins tokens into one
888 with a custom character given by rule attribute.
890 --- 4.2.48 2013/01/10
892 New GFS search member: present_number. This is a hint to the
893 search handler how many records are going to be fetched immediately
894 following search. There's no guarantee that it's going to be the case,
895 since it depends on hit count (for Z39.50 piggyback) and whether errors
898 Make a few functions static (private). The functions getbyte_stream,
899 ungetbyte_stream and yaz_gets are now private. They were never declared
902 yaz-marcdump: exit(5) for serious decoding errors
904 ISO2709 decoding: be more picky WRT header
906 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
907 was only used as to indicate that next-result-set-position should be
909 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
910 Based on patch from Ashley Sanders.
912 Make some functions static/private in PQF parsing. Those functions were
913 never declared in a public header and so should not be in use by
914 applications based on YAZ.
916 --- 4.2.47 2012/11/23
918 ZOOM: special options to control APDU logging.
919 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
920 logging of APDUs until "saveAPDU" option is set again. If logging is
921 already enabled the effect is that current APDU buffer is cleared.
922 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
923 logging (default behavior on new connection).
924 The APDUs sent/received can be obtained by using
925 Using ZOOM_connection_option_get(c, "APDU") or
926 ZOOM_connection_option_getl(c, "APDU", &l).
928 GFS: relay implementation_version from backend
929 From 3.0.40 and later, implementation_version from backend was
930 not used in init response at all.
932 --- 4.2.46 2012/11/15
934 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
935 mode at all. Probably never did.
937 Make a new version of ztest.pem that, at least, is not expired.
939 --- 4.2.45 2012/11/13
941 Fix description of CCL directive 'case'.
943 More tight checking of form arguments (yaz_uri_to_array). Makes
944 YAZ better at rejecting big and/or bad POSTs.
946 SRU decoding does not report more than up to 10 invalid arguments.
948 rpn2cql: less quotes in generated terms. Semantics unchanged, but
949 it's prettier this way.
951 --- 4.2.44 2012/10/25
953 New utility yaz_decode_init_diag. Defined in proto.h.
955 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
956 given for unix local socket.
957 The COMSTACK string for doing so is:
960 unix:/myfile:tcp:localhost:9999/mybase
961 unix:/myfile:localhost:9999/mybase
962 unix:/myfile:http://fakehost/mybase
964 debian: Use dpkg-buildflags in build process.
966 --- 4.2.43 2012/10/19
968 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
969 global's SRU service uses a recordPosition scheme starting from zero.
970 First record's position should be one
971 according to the standard.
973 --- 4.2.42 2012/10/18
975 Allow more namespaces for SRU. This is to allow, for example, an
976 incorrect namespace returned from server
977 http://services.igi-global.com/sru .
979 Minor fixes for compilation on Windows.
981 --- 4.2.41 2012/10/11
983 daemon: log total number of bad signals from child on stop so that it
984 is more easy to spot problems with child worker processes.
986 retrieval: empty backend name attribute omits element set
987 from being used in retrieval.
989 --- 4.2.40 2012/10/04
991 Implement Solr sort strategy "solr", similar to sru11 sorting.
992 This will implement the correct parameters on Solr requst to do
995 --- 4.2.39 2012/09/28
997 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
1000 MARC: Extra/missing indicator handled for MARCXML.
1001 The indicator length is given in header and is the same for the
1002 whole record. If attributes ind1, ind2 are missing, then content
1003 character defaults to blank. Extra indicator attributes (beyond)
1004 indicator length are treated as an error.
1006 Reformat: delete trailing whitespace
1008 --- 4.2.38 2012/09/17
1010 MARC: fix non-ASCII characters for leader. This is to ensure we can
1011 generate XML in UTF-8.
1013 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
1014 in one node with structure word.
1016 --- 4.2.37 2012/09/04
1018 yaz-json-parse: JSON output may be pretty printed by using option
1021 Increase default value of max message for Z39.50 Init for GFS, ZOOM
1022 and yaz-client. Old value was 1 MB. New value is 64 MB.
1024 --- 4.2.36 2012/08/22
1026 yaz-client: don't display bogus records from SRU servers. Some SRU servers
1027 return more records than given by *maximumRecords*. Skipping those in
1030 record_render: simplify buffer return handling and fix at least one bad
1031 memory reference, that broke the test_embed_record sometimes.
1033 Allow http://user:pass@host notation for yaz_url_exec.
1035 zoomsh: allow shell command to be executed. Via the system(3) call.
1037 yaz_poll: Allow num_fds == 0
1039 yaz-client: fix bad encoding of "itemorder item". The itemorder
1040 item <no> - command forgot to use length of encoded Item Request
1041 package. Error present since YAZ 3.
1043 yaz-ztest: fix bad usage of session handle. Bug was introduced when
1044 result sets were saved (271a9c83).
1046 SRU recordPacking: guess record packing in response rather than looking
1047 at the recordPacking element which, OF COURSE, changed semantics in SRU
1050 Decode SRU 2.0 responses. The official namespace for responses, according
1051 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
1052 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
1053 nature.com's server, however, usee namespace
1054 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
1055 we are now using a glob-expr to match up the namespace. ZOOM C and
1056 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
1057 I can not find a single real example showing the "real" namespace in
1058 the documentation from OASIS. The namespace for requests is different
1059 from responses, but this is not added to YAZ yet, when we don't encode
1062 --- 4.2.35 2012/06/26
1064 zoom/record_render: add support for Base64 decoding fo MARC records
1065 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1066 which will decode base64 + ISO2709 marc-8 encoded material from text node
1069 --- 4.2.34 2012/06/07
1071 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1072 and ZOOM_resultset_facets_names.
1074 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1077 Change APDU dump printing to avoid long leading blanks. For levels 16
1078 or larger the level is shown and the indentation is truncated but
1079 recursed with modula 8. This makes it still reasonable easy to read
1080 - even for nested BER dumps.
1082 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1083 return 0 (incomplete package) in case where the BER package was
1084 considered too nested (return value of -2).
1086 dumpber: lines of level 15 are not indented further. Two spaces per
1087 indentation; indentation 15 or more is indented to a fixed indentation
1088 and augmented with a level=<no> indication.
1090 zoomsh: increase max size of command+args
1092 GFS: No limit in RPN buf size in CQL to RPN conversion.
1094 --- 4.2.33 2012/05/09
1096 New function for daemon utility, yaz_daemon_stop .
1098 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1100 --- 4.2.32 2012/04/25
1102 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1103 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1105 --- 4.2.31 2012/04/23
1107 YAZ daemon utility relays SIGUSR1 to child process.
1109 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1110 would result in en empty database list - which in turn would result in
1111 encoding failure for search.
1113 Fix reading beyond string in yaz_sort_spec.
1115 --- 4.2.30 2012/04/11
1117 Add two new SRU diagnostics:
1118 236: Access to specified database denied
1119 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1121 Document the very useful ZOOM-C option "apdulog".
1123 CQL to RPN: term may be passed through verbatim. This is enabled with
1124 truncation.cql . The assumption being that the term is already CQL.
1126 --- 4.2.29 2012/03/20
1128 record_conv: leader spec may be given for marc element.
1129 The leader spec is given as attribute leaderspec for element marc.
1130 For example to convert a MARC21 record from MARC-8 to UTF-8:
1131 <marc inputformat="marc" outputformat="marc"
1132 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1134 record_conv: allow user-XSLT params. For example:
1135 <xslt stylesheet="MARC21slim2DC.xsl">
1136 <param name="myparameter" value="myvalue"/>
1137 <param name="otherparameter" value="othervalue"/>
1140 record_conv: fix error handling for missing marc charsets.
1142 CQL: fix extra terms in wrong order.
1144 --- 4.2.28 2012/03/06
1146 record_conv: modify new API for conversion types. The conversion types
1147 may be passed in new functions yaz_record_conv_configure_t and
1148 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1150 Avoid mixed statement/variable declare; fixes compilation with Visual
1153 --- 4.2.27 2012/02/28
1155 Add non-standard SRU diagnostic: 235: "Database does not exist".
1156 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1157 Update SRU to Bib-1 diagnostic maps accordingly.
1159 CCL: add two new diagnostics for unsupported masking. The new
1160 diagnostics are: "Embedded truncation not supported" and
1161 "Single charcacter mask not supported".
1163 --- 4.2.26 2012/02/23
1165 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1167 --- 4.2.25 2012/01/11
1169 Build YAZ for Ubuntu Oneiric.
1171 CCL: allow parantheses for proximity operands. For example CCL query
1172 (a) % (b) is now allowed.
1174 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1175 marked dead, rather then being destroyed. If not, the session memory is
1176 being free'd before the search/scan handler is finished. Also destroy
1177 'request' memory in request_release rather than in various places,
1178 which resulted in leaks from time to time.
1180 --- 4.2.24 2011/12/21
1182 cql_sortby_to_sortkeys: honor sort prefix.
1184 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1185 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1186 The rpn2cql family of functions now always returns quoted CQL terms.
1188 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1190 --- 4.2.23 2011/12/15
1192 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1193 sequence is treated as one. For example, &&a=b&&&c& is identical to
1196 --- 4.2.22 2011/12/05
1198 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1199 APDUs for a connection to a WRBUF.
1201 --- 4.2.21 2011/11/23
1203 Fix cql_sortby_to_sortkeys. Completely broken before.
1205 Make CCL's @truncation work again.
1207 --- 4.2.20 2011/11/09
1209 New ZOOM connection setting: tproxy. It's like proxy, but does not
1210 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1211 to set resolved address + port for a connection outside ZOOM itself.
1213 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1215 --- 4.2.19 2011/11/07
1217 Fix uninitialized variable in Solr spell support (could cause SEGV
1218 for SRU response decoding).
1220 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1221 back-end's addinfo through into the ZOOM response addinfo.
1223 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1224 they are separated by a colon and a space rather than simply
1227 --- 4.2.18 2011/10/28
1229 Add support for Solr spell-checking/suggestions through ZOOM.
1230 If a Solr target has been configured correctly for spelling-checking
1231 and suggestions, these will now be returned on the ResultSet option
1232 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1234 --- 4.2.17 2011/09/28
1236 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1237 with a flag whether to substitute escape sequences or not.
1239 --- 4.2.16 2011/09/22
1241 Fix nmem_strsplit_escape to substitute escape char properly.
1243 New option for zoomsh -e , which makes it abort on first error and
1244 return process exit code to indicate success/failure.
1246 YAZ options utility supports special option -- which makes all it treat
1247 all following arguments as non-options.
1249 --- 4.2.15 2011/09/16
1251 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1252 searched if absolute filename is given.
1254 Fix conv_xslt() error-reporting when stylesheet is not found.
1255 (The value of fullpath is meaningless in this situation.)
1257 --- 4.2.14 2011/09/07
1259 Fix problem in CQL sort node creation: un-initialized memory.
1261 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1262 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1263 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1266 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1267 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1269 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1270 will make it possible to use both single-character mask (#) and wildcard (?)
1271 in CCL . Throw diagnostic for left truncation because that is not supported
1274 --- 4.2.13 2011/09/01
1276 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1277 cases using escapes (\-sequences) and masking.
1279 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1280 would result in a read one byte beyond string.
1282 rpn2ccl may use Z39.50 masking for terms (t=z).
1284 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1286 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1287 not --cppflags (which seeems like an error in icu-config).
1289 --- 4.2.12 2011/08/27 RPM package only
1291 cql2ccl: fix conversion of terms: operator characters were not
1294 --- 4.2.11 2011/08/25 RPM package only
1296 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1297 CCL parser will map both # and ? to their regular expression
1298 quivalents (. and .*).
1300 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1301 of reserved CQL characters.
1303 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1304 is, so that they are passed through.
1306 --- 4.2.10 2011/08/24
1308 ZOOM SRU mode: more aggressive re-connect.
1310 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1311 made available as a utility function, declared in <yaz/logrpn.h>
1313 rpn2cql_structure() supports proximity nodes (except that the Type-1
1314 proximity node's "exclusion" binary is ignored, as there is no way to
1315 express that in CQL). Fixes bug #4564.
1317 --- 4.2.9 2011/08/18
1319 Fix SEGV that could occur if set command of zoomsh was given without
1320 value (2nd argument).
1322 Fix SEGV that could occur if unsupported transport was given for
1323 COMSTACK - say https (when SSL was unavailable).
1325 Build yaz-url on Windows too.
1327 --- 4.2.8 2011/08/11
1329 New utility to get web content. Header is url.h. A command line tool
1330 yaz-url is part of the distribution and packages.
1332 Fixes for SSL COMSTACK (when gnutls is in use).
1334 New functions yaz_base64{encode,decode}. Header is base64.h.
1336 --- 4.2.7 2011/08/03
1338 ZOOM C includes HTTP response buffer as additional info if it fails
1339 to decode the SRU response.
1341 Make wrbuf_json_puts available.
1343 --- 4.2.6 2011/07/28
1345 zoom: throw diagnostic for invalid value for option "sru". Before a
1346 bad SRU request was sent.
1348 Adding new utility wrbuf_vp_puts.
1350 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1352 --- 4.2.5 2011/07/21
1354 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1355 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1356 redirect was used at the same time.
1358 MARC line mode decoding: be less picky about length given - first
1359 5 digits of header that is.
1361 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1363 Changes to decoding of SRU records: a record with recordPacking=xml is
1364 modified with a new root element <yaz_record> if the recordData contains
1365 multiple children elements. This is to make the record XML parseable
1368 RPN to Solr conversion: encode special characters.
1370 Generic Frontend Server: fix uinitialized member, stepSize.
1372 --- 4.2.4 2011/06/21
1374 Fix a bug in SRU decoding of records.. The database records stored
1375 had un-initialized memory, but it would only be seen with yaz_record_render
1376 and type_spec="ext" .
1378 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1380 --- 4.2.3 2011/06/17
1382 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1384 --- 4.2.2 2011/06/10
1386 Add new utilities to convert from CQL to CCL . These utilities have
1387 prefix cql_to_ccl defined in cql.h.
1389 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1390 lead to memory heap corruptions when ICU utilities were in use.
1392 --- 4.2.1 2011/06/07
1394 Make compilation work without Libxml2.
1396 yaz-client: remove redundant blanks in display of searchResult-1 term
1399 --- 4.2.0 2011/05/18
1401 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1402 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1404 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1405 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1406 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1407 Note that the CQL sortby spec is only converted when the GFS is already
1408 converting from CQL to RPN (cql2rpn element).
1410 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1411 specify whether to collapse delimitors or not. The existing nmem_strsplit
1412 do collapse (collapse parameter = 1).
1414 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1416 Rename internal func yaz_use_attribute_create. While non-static, this
1417 function is not declared in a public header.
1419 --- 4.1.7 2011/03/15
1421 Add -lCrun when linking with ICU on Solaris.
1423 More quicks character set conversions for OPAC records.
1425 --- 4.1.6 2011/03/10
1427 fix problem with record_render: records were converted (character set
1428 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1430 --- 4.1.5 2011/03/08
1432 SRU: add methods for handling DADS SRU-proxy facets.
1434 Separate OPAC record character set for ZOOM_record. yaz_record_render
1435 allows a character set given as charset=from/opacfrom,to where 'from' is
1436 the character set of a bibliographic record, 'opacfrom' is character set
1437 of OPAC record and 'to' is the target character set.
1439 --- 4.1.4 2011/02/21
1441 yaz-client: show may XML format records. Command show followed by 'format'
1442 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1445 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1448 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1450 --- 4.1.3 2011/01/27
1451 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1453 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1454 this package can be distinguished from other vendors.
1456 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1457 as determined by configure
1459 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1461 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1462 returns no error and no record, the present request is considered
1463 partial (only a subset of the records could be returned by backend), and
1464 so it is appropriate to set Present Status to partial-4.
1466 --- 4.1.2 2010/11/02
1468 Move yaz-config man pages to section 1.
1470 More documentation about Solr.
1472 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1473 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1474 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1475 peers on some Linux systems. However, in general that does not work
1476 so YAZ can not rely on that to work. Debian changed behavior in this
1477 respect from Debian lenny to Debian squeeze (still testing as of Oct
1479 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1481 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1483 --- 4.1.1 2010/10/05
1485 Fix yaz-config output: echo_source not set correctly by configure.
1487 --- 4.1.0 2010/10/05
1489 Solr Web Service support for yaz-client and ZOOM.
1491 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1493 --- 4.0.12 2010/08/17
1495 Z39.50 facet support. Facet specifications are passed for search in
1496 other-information with ASN.1 as defined in facet.asn and OID
1497 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1498 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1499 3 is limit (number of entries to get in response). yaz-ztest returns
1500 dummy facets if a client asks for them.
1502 --- 4.0.11 2010/07/09
1504 CCL fixes: bug 2895 and bug 3539.
1506 GR1-display: add comma in display - was removed by mistake in
1509 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1511 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1513 --- 4.0.10 2010/06/18
1515 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1516 result set from a connection. The result set will be on its own
1517 thereafter; no operations on it will perform retrievals from a target.
1518 Only cached copies are returned.
1520 ZOOM C:fix case for HTTP servers responding with Connection:close.
1521 Ensure that if there is a current task it is resumed (like fetching
1522 more records in a result set) . Bug #3484.
1524 PQF parser: use odr_atoi for Odr_int (not atoi)
1526 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1527 values that contain any non-digits are treated as string attributes
1528 (previously decoding only checked for leading character ([0-9]). PQF
1529 encoding: attribute string values are not surrounded by double-quotes.
1531 --- 4.0.9 2010/05/21
1533 New utility for managing threads - thread_create.h.
1535 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1536 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1537 but YAZ' implementation do.
1539 Fixes for yaz_cond-functions on Windows 7.
1541 DLL export more symbols.
1543 zoomsh: show record do NOT render opac.
1545 Remove *.la files from Debian and RPM packages.
1547 --- 4.0.8 2010/05/11
1549 Debian package libyaz-dev depends on libgnutls-dev again (was
1550 removed in YAZ 4.0.6, but due to Libtool it is still needed
1551 even though yaz-config do not list libgnutls libs).
1553 ZOOM: Use only one WRBUF for returning string results for
1554 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1556 ZOOM: ZOOM_connection do not use a shared pointer to
1557 ZOOM_resultset after ZOOM_resultset is destructed by
1558 user. Reverts to YAZ 4.0.4 behavior.
1560 --- 4.0.7 2010/05/04
1562 record-conv: fix problem with at least one XSL conversion -
1563 due to probably incorrect usage of XML XSL documents.
1565 --- 4.0.6 2010/04/29
1567 Fix yaz-config for static mode and the use of SSL (gnutls).
1569 --- 4.0.5 2010/04/29
1571 Forward decl timeval struct in mutex.h and gettimeofday.h.
1573 yaz-config: fix 'static' mode linking.
1575 --- 4.0.4 2010/04/28
1577 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1578 are wrappers for pthreads or Windows. For Windows these are put in
1579 a separate DLL: yaz_cond4.
1581 libyaz.la (whole source) is compiled with thread. If thread support
1582 is enabled enabled, all source of YAZ is compiled with treading support.
1583 This allows core utilities such as yaz_log to use thread facilities.
1584 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1585 thread utilities. This commit moves mutex utilities (mutex.c) from
1586 libyaz_server.la to libyaz.la.
1588 yaz-json-parse displays leading text until error.
1590 --- 4.0.3 2010/04/09
1592 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1593 patch from Giannis Kosmas.
1595 SRU: no longer URL encode SRU database. The URL for an SRU server is
1596 a URL and such is alreeady encoded - at least when given with leading
1597 http:// or https://. This reverts behavior to YAZ 3.0.50.
1599 Support for new MARC XML notation TurboMARC which like MARCXML is a
1600 complete representation of MARC/ISO2709.. This one, however, is more
1601 compact and allows for faster processing with XSLT. TurboMARC can be
1602 used in the marcdisp.h API, from the yaz-marcdump utility and from
1605 yaz-ztest can be configured - via the database - to perform certain
1606 delays when it performs operations search, present and single record
1607 fetch. This allows testers to make yaz-ztest act as a real or even slow
1608 Z39.50 server. Refer to the yaz-ztest man pages for details.
1610 --- 4.0.2 2010/03/09
1612 wrbuf_destroy allows NULL WRBUF passed to it.
1614 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1616 Add ZOOM_connection_close.
1618 No fixed size buffers for ZOOM shell - bug #3257.
1620 tstodr: make it work on s390 platform.
1622 New icu iterator-functions. The new icu_iter-functions makes it possible
1623 to use ICU chains from many threads.
1625 yaz-client: better syntax check for show command.
1627 --- 4.0.1 2010/01/26
1629 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1632 New simple local-file XML include facility which allows file glob-patterns.
1633 Refer to yaz/xml_include.h.
1635 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1638 ZOOM_record_get supports new parameter "format" which makes it format XML
1641 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1642 JSONText in ECMA-262) is JSONValue, not JSONObject.
1644 --- 4.0.0 2010/01/20
1646 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1647 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1649 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1650 POSIX/Unix builds .so with major version 4.
1652 Remove old LOG_-defines from log.h. They have been obsolete and
1653 undefined by default for the last 5 years.
1655 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1657 GFS: Remove socket (int *fd) from search_rr handler. The socket
1658 descriptor ptr is a facility that allowed a search handler to supply
1659 a socket which would serve as a callback - when search was complete.
1660 This facility has now been in use for years.
1662 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1663 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1664 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1665 returns 'const char *' rather than 'char *. The returned string is
1666 read-only and should not be modified by applications. COMSTACK cs_close is
1667 now a void function - it no longer returns int. No applications check for
1668 the value and the implementations has always returned 0.
1670 ZOOM: use size_t for scan hit counts and str size. Functions
1671 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1672 occ (hit count) and len (string length) are now of type size_t pointer
1673 rather than int pointer. This is to be able to represent large hit counts
1674 and to also just to use the proper type for string length (strlen result).
1676 New JSON parser. Refer to include/yaz/json.h .
1678 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1679 Used to be int in some cases. Many wrbuf_-functions used to return an int
1680 indicating some length.. These return values were never used. And so they
1683 ODR: odr_malloc, odr_total now takes size_t for size.
1685 clone_z_type: fix leak; occurred for encoding failures.
1687 --- 3.0.52 2009/12/03
1689 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1690 bug was introduced in 3.0.51.
1692 --- 3.0.51 2009/12/02
1694 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1696 tcpip comstack: fix leak for getaddrinfo.
1698 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1699 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1700 Decoding of SRU "path" database is performed by private function
1701 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1702 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1704 yaz-client: honor base command for SRU. Change when database setting
1705 is applied for SRU and ensure it is kept when a connection is reset.
1706 Change also the way errors are displayed or SRU (decoding of packages).
1708 --- 3.0.50 2009/11/02
1710 Add support for extra request / response data for SRU codecs and GFS.
1711 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1712 for extra data response buffer and length. For the GFS, both request
1713 and response data (XML) is carried in extra_args and extra_response_data
1714 for the search handler. Patch by Ko van der Sloot.
1716 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1717 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1718 10010). This fixes bug #2113.
1720 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1721 cmdfile included a 'quit' command that would result in a memory violation.
1723 --- 3.0.49 2009/10/01
1725 Make a number of functions defined in xmlquery.c static. These have
1726 never been declared in a public header file (yaz/xmlquery.h) and was
1727 made public by mistake.
1729 Improve speed of character conversions (iconv utilities). This makes
1730 conversions from MARC-8 faster.
1732 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1733 unless type desired is "raw". This will prevent type "xml" from
1734 returning ISO2709 .. Which obviously can not be XML parsed.
1736 Fix memory leak in ZOOM that would occur if option apdulog was used
1737 on a re-used connection.
1739 Frontend server logs HTTP requests.
1741 Frontend server now sends Z39.50 close when it times out (sesssion has
1742 been idle for too long). Versions 2.0.30 and earlier also sent close.
1743 But due to a mistake this was disabled in all versions after that, i.e.
1744 the server would just close the socket immediately.
1746 yaz-client emits a better message when receiving an unrecognised
1747 userInformationField.
1749 Skip zero-length subfields when decoding ISO2709. This rare case happens
1750 if a record has two FS characters in a sequence. Without this patch
1751 there would be a reference beyond char array in using_code_len fragments
1754 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1756 --- 3.0.48 2009/08/28
1758 The show command offered by the zoomsh command now takes a 3d optional
1759 parameter type which is what is passed to ZOOM_record. If the type
1760 argument is omitted, "render" is used.
1762 RPN to CQL conv may use USE string attributes (bug #2978).
1764 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1766 --- 3.0.47 2009/07/08
1768 Function yaz_xml2query allows a diagnostic element in the PQF XML
1769 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1770 code and additional info respectively.
1772 The BER BOOLEAN is now the integral type Odr_bool which still happens
1773 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1774 typedef'd to Odr_int. This is still an integral 'int', but it may be
1775 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1776 ASN-1 compiler as well as programs has been updated to use the new types.
1778 --- 3.0.46 2009/06/08
1780 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1781 only the bibliographic record was rendered. For type=opac, an OPAC
1782 record is only returned if it is present.
1784 iconv: small fix for encoding of advancegreek.
1786 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1788 yaz-client: option auto_reconnect=on really reconnects.
1790 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1792 server: avoid null ptr ref for for yaz_poll errors.
1794 build: fix RPM build for RHEL 5.3.
1796 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1798 --- 3.0.45 2009/03/31
1800 Fixed bug #2709: TCP connect returns Invalid argument.
1802 Fixed compilation for mingw.
1804 Honor charset for raw records (ZOOM_record_get).
1806 Fixed use of errno for threaded mode that was seen on Solaris 10.
1808 Fixed argument passing with blanks in value for Windows Service.
1810 Disable YAZ' own log rotate by default (no 1 GB limit).
1811 The variable l_max_size which specifies the log file limit is set to 0
1812 (DISABLED): This is due to the fact that YAZ is most often deployed using
1813 logrotate. Also YAZ can not perform log rotate because of unsufficient
1814 permissions (setuid).
1816 --- 3.0.44 2009/02/17
1818 List supported encodings in man page for yaz-iconv.
1820 Fixed missing SSL libs for --libs output
1822 Re-established OID record syntax application-xml. Nobody should use it
1823 but we don't want to change soname because of this symbol being absent.
1825 --- 3.0.42 2009/02/02
1827 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1829 Added member named_result_sets for init handler struct for the GFS. This
1830 allows a server to disable named result sets.
1832 Removed OID record syntax application-xml.
1834 Added support for rule-based transliterator for ICU wrapper of YAZ.
1836 Fixed bug #1902: yaz-icu XML output.
1838 Make YAZ checks Emacs friendly.
1840 BITSTRING value shows value. Bug #2346.
1842 ISO2709 decoding: skip control characters from indicator data.
1844 Omit sort key by default in yaz-icu's output.
1846 Allow combined single char options (again) for YAZ' options function.
1848 Utility yaz-marcdump got option to display YAZ version (-V).
1850 Allow YAZ to use ICU 3.4.
1852 Added new ICU test case which illustrates removal of diacritics.
1854 --- 3.0.41 2008/12/29
1856 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1858 --- 3.0.40 2008/12/29
1860 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1863 Fixed bug #2352: yaz-marcdump crashes for certain record.
1865 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1867 Added support for Danmarc2 to UTF-8 conversion.
1869 Added support for ISO5426 to UTF-8 conversion.
1871 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1872 implementation version.
1874 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1876 --- 3.0.38 2008/11/10
1878 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1879 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1881 ZOOM C now interprets databaseName option for ZOOM connection as path
1884 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1886 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1888 Dummy Libxml2 types no longer defined in headers of YAZ'.
1890 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1893 --- 3.0.36 2008/09/26
1895 Various ODR chapter fixes.
1897 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1899 Added missing source for Windows compilation, mutex.c.
1901 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1903 For SRU connections in ZOOM all records up to "count" are now fetched.
1905 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1906 in Windows due to bad error handling for Libxml2.
1908 Added facility for sending arbitrary records (ASN.1 any) using
1909 ZOOM C's Extended service update. Patch by Sam Reynolds.
1911 New options for ZOOM C's connection, logapdu which makes ZOOM log
1914 --- 3.0.34 2008/06/18
1916 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1918 --- 3.0.32 2008/06/12
1920 Fixed memory violation that could occur when decoding UTF-8. This bug
1921 was only present in 3.0.30 of YAZ.
1923 --- 3.0.30 2008/06/06
1925 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1926 GNU TLS is used by default (if found).
1928 yaz-ztest returns OPAC records if a client asks for OPAC.
1930 Improved speed of MARC-8 encoding.
1932 Added support for lossy and loss-less MARC-8 encoding.
1934 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1936 Added new Windows Service wrapper (sc).
1938 yaz-client's itemorder command may now send a file.
1940 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1942 Added new function yaz_log_xml_errors.
1944 Allow (but warn) unknown XML attributes in MARCXML parsing.
1946 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1948 The UTF-8 to MARC-8 conversion now uses a different set of characters
1949 for Greek symbols. Bug #2120.
1951 --- 3.0.26 2008/02/21
1953 Added yaz_daemon (daemon.h).
1955 Fixed bug #2068: pkg-config trouble
1957 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1959 --- 3.0.24 2008/01/28
1961 Document --with-xml2 option.
1963 Added OPAC XML XSD (etc/opacxml.xsd).
1965 Allow glob mask for name attribute in retrieval element for the
1966 generic frontend server's retrieval facility.
1968 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1969 except POLLIN/POLLOUT.
1971 Fixed error handling in cs_listen. Bug #2037.
1973 --- 3.0.22 2008/01/20
1975 Fixed version in yaz/yaz-version.h.
1977 Fixed bug #2027: Crash when closing connection.
1979 Changed configure so that ICU support is only enabled if only ICU
1980 and Libxml2 is available (because the ICU chain is XML based).
1982 --- 3.0.20 2008/01/15
1984 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1985 is built. Only this DLL depends on the ICU runtime.
1987 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1988 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1990 Changed license of CCL module to 'Revised BSD'. After consultation with
1991 remaining members of the original EUROPAGATE consortium, we are re-issuing
1992 the CCL module without a separate license. The software was developed by
1993 Index Data as part of a research project. The special license was included
1994 to help feed usage information back to the project consortium to support
1995 project evaluation. At this time, the project consortium has long-since
1996 disbanded, and the majority of the original principals have retired. At the
1997 same time, we have significantly modified the software during the following
1998 years, to the point where very practically no original code remains. To
1999 simplify re-use of the software, we have contacted those members of the
2000 consortium who could be reached, and agreed to re-issue the module as a
2001 proper part of the YAZ package.
2003 Tcl scripts uses /usr/bin/tclsh as preferred shell.
2005 CQL closer to being version 1.2 compliant. CQL also allows free-form
2006 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
2009 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
2010 bug could make Extended services handling crash in the ZOOM layer. This
2011 bug was only present in YAZ 3.0.18.
2013 --- 3.0.18 2007/12/19
2015 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
2018 yaz-marcdump reads and writes collection wrapped records.
2020 Handle OPAC for record conversion module.
2022 Fixes for ICU wrapper.
2024 Allow ICU libs to be controlled with --with-icu .
2026 --- 3.0.16 2007/11/12
2028 Added yaz_poll which is a wrapper for select/poll. When poll is available
2029 and non-buggy, it is used, by yaz_poll . This allows more than 1024
2030 sockets to be in use.
2032 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
2033 functionality through an XML based configuration (ICU chain). This system
2034 is useful for search facilities such as Pazpar2 and Zebra that needs to
2035 perform tokenization of indexed material. The ICU code in a separate
2036 library libyaz3_icu.a.
2038 Added HTTP tunnel facility for COMSTACK, bug #1752.
2039 This is a facility that allows a Web proxy, such as squid, to tunnel
2040 Z39.50 traffic. This facility is "transparent" to must applications
2041 using YAZ. It's enabled by using pseudo transport connect: followed by
2042 the proxy address, followed by command, then follwed by he regular
2043 "virtual" addresss. For example,
2044 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
2046 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
2048 --- 3.0.14 2007/09/21
2050 Fixed bad memory reference in ZOOM_record - cuased by member not being
2051 initialized. This was a problem only in YAZ 3.0.12.
2053 Fixed bug in conversion from MARC to XML: Non-XML characters in control
2054 fields were not removed.
2056 Changed the way C code is generated from codetables.xml. Made a MARC-8
2057 conversion trie for each characterSet section rather than codeTable.
2058 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2059 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2061 --- 3.0.12 2007/09/12
2063 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2064 from ZOOM_record_error).
2066 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2068 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2070 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2072 Better SRW-to-Bib-1 diagnostic mapping.
2074 ZOOM C and yaz-client announces SRU version 1.2 by default.
2076 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2079 Fixed in yaz_sru_decode to allow other version than 1.1.
2081 --- 3.0.10 2007/08/22
2083 Added support for SRU scan for ZOOM.
2085 Added support for the use of the older versions or Extended Service
2086 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2087 set to the version , 1=first, 2=second, 3=third. The third version is
2088 what ZOOM C has used so far. And that, obviously, is the default.
2090 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2091 therefore in Zebra and in SimpleServer-based applications). The new
2092 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2093 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2094 which is passed into the back-end search callback function.
2096 Added support for HTTP Basic authentication in clients: the SRU/W
2097 codec encodes the username/password elements of the PDU structure
2098 appropriately, and these may be set using the "user" and "password"
2099 options in ZOOM-C applications (the same options that are used for
2100 Z39.50 authentication).
2102 --- 3.0.8 2007/06/25
2104 Fixed bug #1208: SSL appears to be broken in ZOOM.
2106 Fixed bug #1206: Libxml2 include path weirdness.
2108 Added oid_name_to_dotstring.
2110 Allow elementSetName to be specified for ZOOM C record update.
2112 Allow waitAction to be specified for ZOOM C based for Extended Services.
2114 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2115 syntax OID. Bug introduced in YAZ 3 series.
2117 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2119 --- 3.0.6 2007/06/06
2121 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2122 directory. yaz-client now reads commands from file given by option -f
2123 if specified; then tries to read .yazclientrc in current directory.
2124 Failing that, it reads .yazclientrc from user's home directory.
2126 Added support for correlationInfo Note and ID for Record Update via
2129 Added yaz-client command querycharset which specifies character set for
2130 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2131 (termListAndStartPoint).
2133 Charset ISO5428:1984 is an alias for ISO5428-1984.
2135 Implemented a way to perform scan in a result set using Z39.50. This
2136 is achieved by attaching the result set name in the characterInfo
2137 (type InternationalString) of OtherInformation in the Scan Request PDU.
2138 The result set is identified in the otherinformation by the new OID:
2139 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2140 This allows for scan in result set and faceted search . Zebra did some
2141 of this in the APT term using attribute type 8 and value being result
2142 set. Using the OtherInformation approach for this is cleaner and easier
2143 to work with in proxies and the like. This facility can be used in
2144 yaz-client using new command setscan which takes a result set as first
2145 argument, start position (APT) as second.
2147 Changed decoding of SRU XML packed records to deal with servers that
2148 have recordData with XML data with multiple root nodes. Also make
2149 comparison for recordPacking case insensitive. Again, one server
2150 returns "XML" where others return "xml".
2152 For SRU responses allow Content-Type application/xml as well as text/xml.
2154 --- 3.0.4 2007/05/21
2156 Fixed bug in character set conversion of BER strings. Bug introduced
2159 --- 3.0.2 2007/05/08
2161 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2163 For OID class, use oid_class consistently.
2165 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2168 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2169 character set for bibliographic information interchange". By Giannis Kosmas.
2171 Added documentation on new OID API.
2173 --- 3.0.0 2007/05/02
2175 Changes to generic frontend server interface: added new member
2176 'query_charset' for bend_initrequest structure. A backend init handler
2177 should set this member to its native character set for query terms.
2178 When defined, the frontend server logic will announce this character set
2179 to a client if the negotiationModel bit is set by the client. All server
2180 implementors are encouraged to specify this. If a backend server does not
2181 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2183 Added CCL utility to remove terms (stop words) from resulting RPN
2184 tree. This is handled by functions with prefix ccl_stop_words_ .
2186 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2187 terms in RPN queries.
2189 Clean-up the CCL API. Moved some internal structures from ccl.h to
2190 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2191 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2192 This is replaced by ccl_parser_find_str which takes a string instead.
2194 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2195 libyaz.la is the core of YAZ except the generic frontend server and
2196 does not depend on POSIX threads anymore. libyaz_server.la is the
2197 generic frontend server facilities and uses POSIX thread functionality
2198 if available. The libyaz.la no longer depends on POSIX threads because
2199 the number of global structures is limited. NMEM no longer re-uses blocks
2200 between threads ; it simply free's memory immediately but allocates in
2201 "large" chunks as usual. We don't expect any performance penalties
2202 because of this. The yaz_log system is still using a global log_level so
2203 caution must be taken when modifying it with yaz_log_init_.. +
2204 yaz_log_mask_str. This, however, should not cause any trouble because
2205 these functions are called during initialization of application code
2206 anyway. `yaz-config --libs server` returns libs for server applications;
2207 `yaz-config --libs` returns libs for non-server applications.
2209 New OID database - with public definitions in oid_db.h. Removed old OID
2210 database including the head oid.h and definitions such as enum oid_value
2211 and struct oident. The new OID database uses the same string names as
2212 before but the 'protocol' is gone. There are now only two representations
2213 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2214 converts from string to OID; functions with prefix yaz_oid_to_string
2215 converts the other way.
2217 Change to emit_term() in CQL-to-PQF query translation: when a term has
2218 the /regexp relation modifier, do not process it for leading and
2219 trailing "^" and "*", which have quite different meanings in regular
2222 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2223 write handlers no longer carries a 'last' parameter. This will make
2224 yaz_iconv flush "less" characters. A flush is performed by call to
2225 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2227 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2228 removed, because function yaz_query_to_wrbuf does the same.
2230 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2231 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2233 Deprecated MARC utility functions removed.
2235 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2238 Branch split: YAZ_2_1_55_branch
2240 --- 2.1.54 2007/03/16
2242 Fix to ZOOM-C so that transparent reconnection is properly handled on
2243 connections that are in asynchronous mode.
2245 Fixed compilation on OpenBSD 4.0.
2247 Large strings in GRS-1 records are now properly displayed in yaz-client.
2249 Added character conversion support for "advancegreek"; based on patch from
2252 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2253 sequence is met. Before the error was not set so it would be unknown.
2255 Adjust yaz-marcdump MARC reader so that it skips until record separator
2258 --- 2.1.52 2007/03/07
2260 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2261 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2262 fd_set structure used as a bitmask for the FDs to be selected on.
2264 Using ACX_PTHREAD macro to check for POSIX threads.
2266 Fixed have-vsnprintf check.
2268 --- 2.1.50 2007/02/23
2270 Fixes for configure on BSD. Bug #900.
2272 Added snprintf/vsnprintf wrappers for systems that don't have
2273 limits (heavens forbid).
2275 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2276 created before all previous tasks were completed and removed from the
2277 task queue, the new task could be removed by a mistake.
2279 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2281 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2283 Fixed bug #832: Problem with MARC/charset in yaz-client.
2285 Fixed bug #668: save command line history for yaz-client.
2287 Fixed bug #830: pkg-config support.
2289 --- 2.1.48 2007/01/23
2291 Extended ZOOM result set options with two options that may be read by
2292 a client: resultSetStatus and presentStatus with values as specified for
2294 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2296 Fixed bug #827: Using SSL fails on Debian etch.
2298 Fixed bug #826: Weird looking chars for set of MARC records.
2300 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2301 that is treated as an ItemOrder with itemRequest being an XML document
2302 external. The value of "doc" is the content.
2304 Extended the GFS search facility. New member of bend_search_rr
2305 'estimated_hit_count' signals that hits is known to be an estmate
2306 (higher or lower than real hit count). New member 'partial_resultset'
2307 signals that the search was partial (hit count is lower or equal than
2308 real hit count). For Z39.50, the information is stored in resultSetStatus
2309 member of SearchResponse APDU. For SRU, the information is signalled
2310 via SRU diagnostic 59: "Result set created with valid partial results
2313 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2315 --- 2.1.46 2007/01/13
2317 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2319 Added ZOOM_connection_peek_event.
2321 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2322 the following new functions:
2323 ZOOM_event_nonblock, ZOOM_connection_process,
2324 ZOOM_connection_get_{socket,mask,timeout},
2325 ZOOM_connection_fire_event_{timeout,socket}.
2326 The existing blocking event handler, ZOOM_event, is a wrapper for the
2327 + blocking ZOOM_event_sys_{poll,select}.
2329 Implemented function ccl_xml_config which parses XML version of CCL
2330 configuration (bug #798).
2332 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2334 Added timings utility (yaz/timing.h)
2336 --- 2.1.44 2007/01/03
2338 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2341 Fixed bug #779: Rotation of apdu.log fails.
2343 Fixed for character set conversions:
2344 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2345 Honor G1 set in MARC-8 decoding.
2347 --- 2.1.42 2006/12/17
2349 Fixed bug #775: char conversion does not handle Alternative UTF-8
2352 Implemented function yaz_marc_read_line which parses MARC line format
2353 records. There is a wealth of formats out there. So far, this function
2354 reads line records produced by yaz_marc_write_line.
2356 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2357 more generic and easier to remember(!) options: -i format and -o format
2358 which specifies input format and output format respectively - where
2359 format is one of "marc", "marcxml", "line", "marcxchange".
2361 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2362 does not print anything except warnings for records.
2364 For yaz-marcdump, added support for MARC split into files (-s) with a given
2367 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2368 spec, at http://www.loc.gov/standards/sru/record-update/
2369 This has changed the binary layout of the following structs:
2370 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2371 bend_update_rr . Patch by Ko van der Sloot.
2373 Added GFS utility function bend_assoc_is_alive which returns 1 if
2374 association is still alive (client is connected); 0 otherwise (client
2375 closed connection). This allows busy servers to stop working for
2378 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2379 been a separate piece of software. This version of ziffy has been modified
2380 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2382 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2384 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2385 Client code may now interrogate options such as "init_opt_sort" to
2386 find out whether the server claims to support various options.
2388 --- 2.1.40 2006/11/27
2390 Added utilities yaz_{set,get}_esn to set/get element set name from
2393 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2394 of YAZ and has been so since YAZ 2.1.10.
2396 Implemented ZOOM_record_error which returns error information for
2397 record (surrogate diagnostic).
2399 --- 2.1.38 2006/10/31
2401 Updates for SRU Update by Ko van der Sloot:
2402 1. Changed name from "operation" to "action"
2403 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2404 versions in the code, marked as 'backward compatible'.
2405 3. Added diagnostics for SRU Update.
2407 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2409 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2411 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2413 For GFS, fixed problem with SRU diagnostic 'First record position out of
2414 range' being issued for 0 hits.
2416 zoomtst10 part of Windows Build.
2418 --- 2.1.36 2006/10/13
2420 Implemented yaz_filepath_comp which splits a path into file path
2421 components (required by Zebra 2.0.3+).
2423 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2424 BSD inspired license until now so this should not have any real impact on
2425 anybody. See http://www.opensource.org/licenses/bsd-license.php
2427 Fixed bug #687: Missing log lines.
2429 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2432 Fixed bug #689: SRU diagnostics to be added.
2434 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2435 whether a connection is idle (no more work do do).
2437 --- 2.1.34 2006/10/04
2439 Change type of optval from long to int for invocation of setsockopt with
2440 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2442 Added support for specifying the max log file size for the Generic
2443 Frontend Server. The size is given with option -r.
2445 --- 2.1.32 2006/09/21
2447 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2449 --- 2.1.30 2006/09/17
2451 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2454 Fixed bug in Generic Frontend Server that could cause a server to stop
2455 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2457 For the generic frontend server, the maximum record size is used as maximum
2458 size of incoming packages (SRU + Z39.50). The value until was previously
2459 only used in Z39.50 Init negotiation and, later, in a session controlled
2460 sizes of records returned. This is controlled using -k option. It can be
2461 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2463 --- 2.1.28 2006/09/04
2465 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2468 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2470 New option for yaz-marcdump -lpos=value which allows setting a portion
2471 of MARC header to a certain value.
2473 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2475 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2476 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2478 --- 2.1.26 2006/08/15
2480 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2483 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2485 --- 2.1.24 2006/08/08
2487 Fixed MARC ISO2709 encoding routines to deal with character set
2490 Minor changes to GFS logging. Database included in search request log
2493 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2494 cached/multiple records.
2496 Shared libraries are built by default on Unix+configure.
2498 Changed cql2pqf transformation to use a different evaluation order. The
2499 new order is: always, relation, structure, position, truncation, index
2500 and relationModifier. Old order was: always, relation, relationModifier,
2501 structure, index, position, truncation. Note that the the latter ones
2502 override former ones for identical attributes.. The new scheme means that
2503 it is possible to override any existing attribute with a relationModifier.
2504 And also that it is possible to override everything for the index rule
2505 (except the ones listed in relationModifier). No order is perfect but this
2506 one, we believe, covers more real cases.. The "always" should have been
2507 called "default", since the attributes there can be overridden with all
2510 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2511 compilation phase, but also for yaz-config --cflags output. This allows
2512 us to have public headers with Libxml2 stuff in them . It should also,
2513 eventually, make Libxml2 checks redundant in packages using YAZ, such
2516 --- 2.1.22 2006/06/15
2518 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2519 stored in uri, message and details.. Previously diagnostics were stored
2520 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2521 compatibility.. but he's probably the only one affected, so.
2523 Added support for CCL, compiled on the client side, in ZOOM-C. This
2524 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2525 input; the resulting query objects can be used for for searching with
2526 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2528 YAZ' configure searches for OpenSSL by default.
2530 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2531 SL_CTX_use_certificate_file. See
2532 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2533 for more info. Thanks to Ko van der Sloot.
2535 --- 2.1.20 2006/06/02
2537 Bug #600: SRU GET, POST support for yaz-client. Introduced
2538 command 'sru' which selects method SOAP/GET/POST.
2540 Allow missingValueAction to be specified for the sortspec string -
2541 function yaz_sort_spec. By default, the missing value action is null.
2542 Use ! to specify "abort". Use = followed by stringvalue to specify default
2545 Ensured that Present-handler (if defined) is called in GFS before any call to
2546 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2547 searchRetrieve requests.
2549 Documentation for YAZ is now based on the Docbook XML/XSLT using
2550 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2551 is no longer depending on jade/openjade or docbook-to-man scripts.
2552 PDF is no longer part of the distribution - but can optionally be
2553 made using DSSSL/jadetex or FOP.
2555 Added retrieval handling support in Generic Frontend Server to support
2556 conversion between MARC/XML as well as XSLTtransforms. See
2557 etc/yazgfs.xml for an example.
2559 Added Authentication support to Generic Frontend Server in SRU
2560 mode. Authentication using HTTP Basic is supported, as is the use
2561 of 'x-username' and 'x-password' parameters in the request itself.
2563 Added support for a new character set MARC8s identical to MARC8 except
2564 that it converts combined characters to single Unicode characters in the
2565 Latin-1 range (when possible).
2567 --- 2.1.18 2006/04/24
2569 ASN.1 compiler 0.4: generates brief Doxygen file header for
2570 generated .h/.c files.
2572 Utility yaz_iconv now supports conversion to MARC-8.
2574 New facilities for the MARC module. The reading - and writing of
2575 content are separate methods for the yaz_marc_t handle. The following
2576 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2577 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2578 format). Write functions have prefix yaz_marc_write_.. The existing
2579 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2580 available. Removed support for OAI-MARC and simplexml (not the
2581 simplexml from PHP5).
2583 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2584 to be returned for this connection.
2586 --- 2.1.16 2006/03/31
2588 Allow multiple languages and charsets to be specified with
2589 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2590 negcharset iso-8859-1,utf-8
2592 Translation of proximity nodes from CQL into PQF now works.
2594 Moved to automake 1.8, 1.9.
2596 Added function yaz_log_set_handler which allows a log handler to be
2597 installed. This handler will be called for all log messages. Output
2598 to file is also produced; but that can be disabled by passing NULL
2599 fname to yaz_log_init_file.
2601 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2603 For SRW (including GFS), accept application/soap+xml as content-type
2606 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2607 produces NO stylesheet reference even if a default stylesheet is specified
2610 --- 2.1.14 2006/03/14
2612 Updated Windows package to include yazd.dll + yazd.lib for the
2613 Development component.
2615 If the environment variable YAZ_LOG is set, then it is used as a
2616 string indicating the default level of logging to use if not
2617 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2618 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2619 used as before. So, for example, to omit warnings from YAZ logging,
2620 export YAZ_LOG=-warn
2622 cql_transform() now map structure and other attributes before indexes,
2623 so that index-specific structures and other attributes can override
2624 defaults. So now a combination of mapping specifications such as:
2626 index.dc.date = 1=date-modified 4=5
2627 does the right thing.
2629 cql_transform() now also respects the "always" mapping specification,
2630 which establishes an initial set of attributes to be used for all
2631 terms except where overridden by more specific attributes associated
2632 with the index, relation or modifier.
2634 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2635 which mode to use; one of "post", "get" or "soap" (SRW, default).
2637 Fixes for yaz_iconv routines: changed trie-based character set conversions
2638 to use only non-negative values for bit fields due to Sun's C compiler not
2639 supporting negative values.
2641 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2642 sequences where not read correctly. Fix by Rustam Usmanov.
2644 Updated win/makefile to use options, settings which makes things
2645 compile with VS C 2005.
2647 --- 2.1.12 2006/02/01
2649 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2651 In ZOOM socket code, use select instead of poll on MacOSX.
2653 ZOOM-C now support client-side compilation of CQL into RPN that is
2654 sent to the server, enabling CQL to be used against all Z39.50
2655 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2656 ZOOM_query object, and submit it using ZOOM_connection_search().
2657 The CQL-to-RPN translation uses a configuration file, the name of
2658 which must be specified in the Connection's "cqlfile" option.
2660 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2661 function, which takes as its start-term parameter a ZOOM_query object
2662 (which may have had either CQL or RPN set into it).
2665 --- 2.1.10 2005/11/29
2667 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2668 GFS to support this as well. Backend handler, bend_srw_update, does the
2669 update work. Code contributed by Ko van der Sloot.
2671 Allow retrieval of Search Result-1 information in ZOOM by the use of
2672 options that are attached to a result set. ZOOM documentation updated
2675 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2676 UTF-8 conversion. Patch by Raj Patel.
2678 Added option -m to GFS to control formatting of timestamps in log file.
2680 Added 'exit' as synonym for 'quit' in yaz-client
2682 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2683 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2684 for the new members. Patch by Ko van der Sloot.
2686 Added support for SRU POST. It is supported for content-type
2687 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2689 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2690 Instead make the library libyaz.la multi-threaded. Threading as a whole
2691 can still be disabled by configure option --disable-threads. Previosly,
2692 with older GLIBCs there were problems with MT libs under Apache. This
2693 has now been fixed a long time ago.
2695 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2698 CQL module modified to be case insensitive for relations/indexes/operations.
2700 Fixed bug in CQL transform code: incorrect value relationModifieder
2703 Added 'show all' command for yaz-client which retrieves all results
2706 Added new yaz-client, xmles, which takes a (private) OID and
2707 a document to be sent as an extended service request.
2709 Describe new yaz-client commands wait_response and set_auto_wait.
2711 Increase TCP/IP listener backlog from 3 (which I am guessing was
2712 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2713 that the socket will queue as many incoming connections as it's able
2714 to handle ongoing connections. In other words, it will never now
2715 refuse a connection that it would be able to handle merely because
2716 it's not got around to accepting() enough of the pending connections
2717 yet. This is the behaviour anyway under Linux, where the listen()
2718 argument is ignored; but not under BSD and on systems such as
2719 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2720 YAZ-based servers should now be uniform across operating systems in
2723 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2724 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2725 This allows yaz-marcdump to read large MARC batches (>2 GB).
2727 Modified all YAZ source files - except the source which is auto-generated
2728 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2731 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2732 corresponding to the existing *_setl() function. These allow option
2733 values containing arbitrary valuues.
2735 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2736 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2737 except that it returns an indicator of whether or not the sort
2738 criterion was accepted (0 for OK, -1 for invalid).
2740 --- 2.1.8 2005/06/07
2742 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2743 MARC output rather than returning "new" buffer.
2745 yaz-client warns about unknown init options.
2747 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2749 --- 2.1.6 2005/05/24
2751 Added support for SRW sort in Generic Frontend Server. Patch
2752 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2753 sortKeys - or NULL if none is provided.
2755 Fixed bug #307: It was impossible to specify indefinite/no timeout
2756 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2759 Added support for multiple languages and charsets to be specified in
2760 ZOOM. Each charset/language is separated by a blank. If negotiation is
2761 in effect in init-response, Option
2762 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2763 Code based on patch by Vasiliy Osadchuk.
2765 Fixed bug #306: infinite recursion that occurred when calling
2766 yaz_log_level_init as the first call (before other log level or
2769 Fixed bug in scan handling in front end server: if preferred-Position-In-
2770 Response was non-present, a NULL pointer referece was performed.
2772 --- 2.1.4 2005/04/26
2774 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2775 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2776 now defined for all those error codes. So instead of putting 109 in
2777 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2778 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2780 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2783 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2785 Program yaz-client now exits and produces an error message if multiple
2786 Z39.50 servers are specified on the command line (none or one allowed
2789 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2792 --- 2.1.2 2005/03/16
2794 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2796 Fixed bug #272: Preserve spacing for CCL terms.
2798 --- 2.1.0 2005/03/14
2800 Added support for virtual hosts and multiple backend servers for
2801 the YAZ frontend server. The configution is XML based and
2802 support specificition of CQL to RPN mappings and explain information.
2803 See section "Virtual Hosts" in the YAZ manual.
2805 Extended OPAC display utility. OPAC display utility renders
2806 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2807 to supplement yaz_marc_decode_wrbuf.
2809 Fixed a bug in MARC decoder that could caused it to crash for some
2810 invalid MARC records. More diagnostics and warnings where added in
2811 XML output (warnings, etc are stored in comments).
2813 --- 2.0.34 2005/02/08
2815 Fixes for UNIX domain sockets. Bug #261.
2817 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2819 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2820 Added yaz_marc_subfield_str which defines subfield lead string which is
2821 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2822 yaz_marc_endline_str which defines end of fields string used in
2823 YAZ_MARC_LINE format. Default string is newline.
2825 Experimental support for MarcXChange. This format can be produced
2826 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2827 http://www.bs.dk/standards/MarcXchange.xsd
2829 Added yaz-client commands scansize that sets maximum number of
2830 entries to be returned by scan.
2832 --- 2.0.32 2005/01/11
2834 Added support for SRW scan in yaz-client and Generic Frontend Server.
2836 * Added whereInList member to SRW Scan Term.
2838 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2840 Fixed NMEM system to return aligned blocks on the smallest boundaries
2841 that are suitably aligned for all possible types on the particular
2842 architecture YAZ is being built for.
2844 --- 2.0.30 2005/01/04
2846 Fixed numerious warnings that was issued with newer versions of GCC.
2848 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2849 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2852 Make YAZ Generic Frontend Server slightly faster.
2854 Enhance (and reduce) logging for Generic Frontend Server.
2856 Revert YAZ log system so that it flushes every write operation
2857 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2859 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2860 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2861 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2862 will effectively disable old definitions.
2864 --- 2.0.28 2004/11/09
2866 Added yaz_log_time_format which specifies log format using
2869 Added yaz_log_module_level which returns mask for a module. Value
2870 is non-zero mask a if module is enabled; zero if disabled.
2872 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2873 in include/yaz/cql.h.
2875 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2877 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2879 Fixed bug #172: RPM builds does not enable SSL.
2881 Doxyfile.in part of dist. Doxyfile generated by configure.
2883 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2884 are given and the corresponding component does not exist.
2886 Extend CCL documentation in YAZ reference. Describe r=r.
2888 --- 2.0.26 2004/10/01
2890 Fixed MARC->MARCXML conversion to properly deal with
2891 fields, subfields, indicators having non-ASCII characters.
2893 Fixed MARC->MARCXML conversion so that ASCII control characters
2894 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2897 Added YAZ GFS support for conversion from Z39.50 surrogate
2898 diagnostics to SRW surrogate diagnostics.
2900 Bug fix: YAZ GFS did not return schema in explainResponse.
2902 --- 2.0.25 2004/09/30
2904 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2905 now converts recordSchema to elementSetName as well as schema URI.
2907 Fixed bug in COMSTACK that prevented HTTP request packages from being
2910 --- 2.0.24 2004/09/29
2912 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2913 does not require white-space before and after the dash in a range, e.g.
2914 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2917 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2918 due to new GCC removing "redundant" code.
2920 Added yaz-client commands scanpos and scanstep that sets preferred
2921 position and step-size for scan.
2923 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2925 Added CCL utility ccl_qual_buf which parses one or more CCL
2926 spec lines in a buffer.
2928 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2929 of name and value - ignoring empty lines and comments.
2931 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2933 Added odr_get_element_path which returns current element path for an
2934 ODR handle. This utility is useful in error handling or user-defined
2937 Added ODR_PRINT utility odr_set_stream which is is a more generic
2938 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2939 to a write function and pointer to close function. The close function - if
2940 non-NULL - will be called during odr_destroy.
2942 Fixed bug in CCL parser where truncation char was not removed from
2943 right side when truncation=both was in effect.
2945 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2948 --- 2.0.23 2004/08/11
2950 Fix buffer overrun in CQL parser when dealing with proximity (%).
2952 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2953 to UTF-8/UCS conversion is now only based on codetables.xml.
2955 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2957 --- 2.0.22 2004/08/06
2959 Add support for more "commit changes" in ZOOM (uses Extended Services).
2961 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2964 Yet another small fix for configure of SSL.
2966 --- 2.0.21 2004/05/14
2968 Fix SSL libs for configure when --with-openssl=DIR is given.
2970 --- 2.0.20 2004/05/10
2972 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2974 SSL comstack now uses yaz.pem certificate file on server side
2975 by default. Certificate filename can be configured by calling
2976 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2978 Fix bug regarding multiple calls to ZOOM_connection_connect.
2980 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2982 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2983 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2985 ZOOM now allows inspection of X509 peer certificate for verification.
2986 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2988 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2989 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2990 as "modular" but it simplifies things.
2992 Added cs_get_peer_certificate to that returns peer X509 PEM.
2994 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2995 NULL if SSL is unavailable.
2997 Documentation about MARC decoding tools.
2999 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
3001 --- 2.0.19 2004/03/30
3003 Rename CHANGELOG to NEWS to follow GNU style packing.
3005 Fix bug with missing initialization of member in init_diagnostics.
3006 This bug affects threaded version of GFS server.
3008 --- 2.0.18 2004/03/20
3010 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
3013 Ensure zlib.dll is packed with Windows install.
3015 --- 2.0.17 2004/03/17
3017 Fix encoding of xsd:string to use text instead of CDATA.
3019 Fix endless loop in CQL parser with unbalanced ".
3021 Use a more compact way to store MARC-8 conversion tables.
3023 --- 2.0.16 2004/03/16 Debian only
3025 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
3028 Update CQL parser to use new CQL 1.1 modifiers for booleans and
3033 --- 2.0.15 2004/03/01
3035 Another fix for decoding of XML packed records.
3037 --- 2.0.14 2004/02/25
3039 Fixes for Chunked encoding. White space not ignored after length spec.
3041 Update NS and use default NS for SRW diagnostic elements.
3043 --- 2.0.13 2004/02/23
3045 Implement ZOOM_resultset_cache_reset which resets record cache.
3047 Implement ZOOM_resultset_sort which sorts a result set.
3049 Implement chunked HTTP transfer.
3051 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
3053 --- 2.0.12 2004/02/16
3055 Added member 'schema' to bend_explain_rr structure so that backend
3056 can specify explain record identifier. Defaults to Zeerex 2.0.
3058 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3060 --- 2.0.11 2004/02/16
3062 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3065 Added init command for yaz-client which sends "extra" init request.
3067 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3068 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3070 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3072 Make ZOOM error code for "invalid query".
3074 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3076 --- 2.0.10 2004/02/05
3078 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3081 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3083 Added option -p <file> to make Generic Frontend Server to write PID file.
3085 Added option -D to put Generic Frontend Server in background on its own.
3087 Make ZOOM C recognize option "password". If unset, "pass" is used
3088 (for backwards compatibility).
3090 Fixed a bug in Generic Frontend Server that could make it crash if a
3091 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3094 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3095 Must be issued before open, in order to be in effect.
3097 --- 2.0.9-6 2004/01/12 Debian/Windows
3099 Make the SRU server more picky WRT unknown params, etc.
3101 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3103 New YAZ client command, options, that sets Z39.50 options.
3105 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3106 options from a string of tokens (one token for each option bit).
3108 Update SRW diagnostic code messages.
3110 --- 2.0.9-5 2004/01/07 Debian/Windows
3112 Handle user defined stylesheet for SRW/SRU.
3114 --- 2.0.9-4 2004/01/06 Debian/Windows
3116 Fix bug in decoding of Content-Length.
3118 --- 2.0.9-3 2004/01/06 Debian/Windows
3120 Fix a bug with decoding of XML packed records.
3122 --- 2.0.9-2 2004/01/05 Debian only
3124 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3126 Fix bug in SRW/SRU diagnostics decoding.
3128 --- 2.0.9 2004/01/05
3130 Fixed bug in Generic Frontend Server which could drop records exceeding
3131 preferred message size. Reported and fixed by Irina Dijour.
3133 Fixed calculation of package size for structured records in Generic
3134 Frontend Server. Reported and fixed by Irina Dijour.
3136 Fixed namespace for SRW/SRU diagnostics.
3138 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3140 --- 2.0.8 2003/12/22
3142 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3143 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3146 CQL changes to reflect recent changes to the specification:
3147 * Documentation talks about context sets instead of index sets.
3148 * Documentation talks about indexes instead of qualifiers.
3149 * The CQL-to-PQF transformer's configuration file now uses
3150 "index.set.name = <attributes>" instead of the old form
3151 "qualifier.set.name = <attributes>". (Both forms are still
3152 understood but the latter is deprecated.)
3153 * CQL terms with no explicit index specified are now interpreted as
3154 cql.serverChoice instead of srw.serverChoice (which of course
3155 behaves exactly the same.)
3157 --- 2.0.7 2003/12/16
3159 MARC conversion can now generate ISO2709 output in another
3160 character set. yaz-marcdump uses this facility if you invoke it
3163 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3164 functions from there can be used from C++.
3166 --- 2.0.6 2003/12/04
3168 Frontend server now transfers memory from decoded packages to stream
3171 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3172 references to show up.
3174 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3175 the ZOOM Abstract API. The older names for the same options are still
3176 also supported for the benefit of old applications.
3178 ZOOM-C supports "implementationId" and "implementationVersion" options
3179 to go along with "implementationName". These allow the user code to
3180 specify identification strings to be sent to servers.
3181 Add OID for the new ExtLite attribute set.
3183 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3184 as requested/supplid by Ere Maijala <ere@atp.fi>
3186 For generic frontend server, reverse the order of
3187 "toolkit-supplied / application-supplied" strings sent as implementationId,
3188 Name and Version. Also, remove the spaces around the slash. This brings
3189 the GFS in line with the behaviour of ZOOM-C on the client side.
3191 Add function ZOOM_scanset_display_term.
3193 yaz-client shows scan displayTerm if present.
3195 Utility yaz-iconv is now installed by default along with the man page
3198 Extend configure check for OpenSSL to use pkg-config where available (such
3201 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3202 server to specify uid/gid/mask for socket using the format
3203 unix:[user=uid,][group=gid,][umask=mask,]file=path
3204 If file= is omitted the existing format is assumed, e.g.
3206 in which case the mask is 0666 (rw for everybody).
3208 Major restructure of YAZ source. All source in libyaz is in src directory.
3209 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3210 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3212 Added man page for utility yaz-marcdump (used to be called marcdump).
3213 yaz-marcdump is installed by 'make install'.
3215 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3216 of incoming package failed.
3218 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3220 Change prototype of odr_perror: add const to message string.
3222 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3224 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3225 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3226 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3227 DNS lookup. There should not be any compatibility problems with this
3228 assuming that blocking=1 or 0 is used.
3230 Fix bad reference in UNIX comstack in function cs_addrstr.
3232 Fix for compilation on AIX.
3234 The generic front-end server (server/seshigh.c) now supports returning
3235 Init diagnostics to the client in User-information-field, in
3236 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3239 --- 2.0.4 2003/09/04
3241 Allow any CQL relation (not just all,any,exact,scr).
3243 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3244 that features the same UI.
3246 Implemented command update0 in YAZ client which is equivalent to
3247 update but uses old of Ext Update ASN.1.
3249 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3250 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3251 Previously no OID was used for this info.
3253 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3254 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3255 returns 'malformed search term' otherwise.
3257 SortResponse member resultCount now set to NULL in sort handler of
3260 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3263 Add three new utility functions for translating OIDs between various
3264 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3265 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3266 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3267 char *oid_to_dotstring(const int *oid, char *oidbuf);
3268 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3270 Reverted modifications for ES Update definition for z_IU0Update
3271 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3272 is back to YAZ 2.0.2.
3274 String value attributes for CCL parser.
3276 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3277 which their FirstSearch server returns in Init responses, sometimes
3278 carrying useful diagnostic information when Init fails. This has the
3279 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3280 "z39.50/oclcui.asn", where its definition is somewhat different from
3281 what OCLC document on their web-site, as required to interoperate with
3284 Support for anonymous authentication in yaz-client. Use the command
3287 * Fix the OID of the Index Data-local "admin" Extended Service from
3288 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3289 the 1000, which indicates a locally-defined OID, was a mistake.
3291 --- 2.0.3 2003/06/20
3293 Fix CCL directive @case handling so that it affects string match for
3294 both CCL keywords and qualifiers.
3296 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3297 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3298 Decoder has been updated with ASN.1 changes as listed in
3299 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3300 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3301 z_IUUpdate, remains unchanged.
3303 ZOOM_record_get may now return a record in a specific character set.
3304 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3305 "from" is the character set of record as returned by target. "to" is
3306 the character set to be returned. If omitted, "to" is UTF-8.
3308 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3310 New ODR utility, odr_getelement, which returns name of element for
3311 which encoding/decoding failed.
3313 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3314 in cases where a required element was omitted.
3316 Bug fix: some MARC8 sequences were not converted.
3318 New ZOOM option "step" which specifies number of records to be
3319 retrieved in one chunk. Used in conjunction with "start" and "count".
3321 SRW support for yaz-client. Use scheme http: to use it, e.g.
3324 yaz-client no longer does (un)intelligent character set conversions
3325 by default. Can be enabled with charset and marc_charset commands.
3327 xmalloc trace fix for 64-bit systems such as DEC alpha.
3329 Solaris 2.6 compile fix.
3331 New function, cql_strerror() translates SRW error codes, as returned
3332 by cql_transform_error(), into human-readable English strings. Used
3333 in yaz-client diagnostics when appropriate.
3335 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3336 converts it into a type-1 query which is sent to the server. This
3337 makes CQL available for use with all Z-servers, as opposed to the tiny
3338 minority that can handle CQL queries themselves.
3340 --- 2.0.2 2003/04/28
3342 New Debian package layout similar to the Redhat Package layout.
3344 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3345 and search result respectively.
3347 --- 2.0.1 2003/04/25
3349 Redhat package is now several packages: libyaz (runtime libraries),
3350 libyaz-devel (development and documentation, and yaz (utility programs).
3351 Package spec file by Morten Bogeskov.
3353 New member 'schema' in struct bend_fetch_rr which the name of requested
3354 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3355 handler MAY set this to reflect the schema of the returned record.
3357 New member 'display_term' in struct scan_entry. GFS now sets member entries
3358 and allocates scan entries to be filled by user scan handler. In previous
3359 version, entries member was allocated by the scan handler. That still works,
3360 but the GFS will ignore member display_term - assuming it was NOT set by
3361 the handler. The fact that the GFS now allocates the entries both allows
3362 for new members and makes a scan handler easier to write.
3364 Fix CQL lex buffer overflow.
3366 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3367 SRU default recordPacking is string.
3369 SRU protocol support for frontend server.
3371 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3373 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3375 Added scan for the ZOOM shell (zoomsh).
3379 * String Identifers for Schemas (Amendment 5).
3380 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3381 Old definition for schema
3382 Odr_oid *schema; /* OPT */
3387 Z_InternationalString *uri;
3388 #define Z_Schema_oid 1
3389 #define Z_Schema_uri 2
3392 * resultCount parameter to Sort Response (Amendment 1).
3393 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3395 Support for SRW 1.0 over HTTP. This is an optional feature and
3396 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3399 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3400 on the same port. SRW SearchRetrieveRequests are mapped
3401 to bend_init,bend_search,bend_fetch,bend_close.
3403 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3405 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3406 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3408 ZOOM connections are SRW based if schem http is used for hostname
3409 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3410 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3412 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3413 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3414 distance=n, order=true/false, relation=le, prox unit=word. If
3415 n is omitted, distance 1 is used.
3417 Fixed problem with C compiler include path in wrong order.
3419 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3420 on Solaris. Patch from Ko van der Sloot.
3422 New MARC decode API. All new functions operate on a yaz_marc_t
3423 handle. The most important new functions are: yaz_marc_create,
3424 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3425 decode and destroy respectively. Decoder can produce formats
3426 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3427 include/yaz/marcdisp.h.
3429 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3430 to UTF-8, UCS-32, wchar_t or Latin-1.
3432 * Prototypes for yaz_iconv_-functions moved to separate header
3433 include/yaz/yaz-iconv.h.
3435 Make a few private functions 'static' in unix.c. This prevents
3436 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3438 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3439 are set when Init Response is received.
3441 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3442 but returns diagnostic set as well.
3444 New function yaz_strerror which is a portable wrapper for
3445 strerror/strerror_r/GetLastMessage.
3447 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3448 is returned for MARC. If type is "oai", then OAI MARC is returned.
3450 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3453 --- 1.9.2 2002/11/26
3455 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3457 Fix bad race conditions on SIGTERM and terminate gracefully in
3460 Move retrieval (data1) module to Zebra since nobody seems to be
3463 Add GRS-1 render for ZOOM using same format as yaz-client.
3465 --- 1.9.1 2002/10/05
3467 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3469 Fix broken ESpec handling in data1 module.
3471 SGML reader parses comments and makes them part of the data1 tree.
3473 Added several type casts so that YAZ compiles as C++ code.
3475 ZOOM didn't handle PDU encoding failures properly.
3477 Added more Bib-1 diagnostics (approved extensions).
3479 GNU configure: better check for iconv.
3481 More portable use of accept, getpeername. Check for socklen_t. Use
3482 int/size_t if socklen_t is not defined.
3486 PQF parser rejects bad queries - including those with extra
3487 characters in them. PQF parser used to silently ignore that.
3488 Cleaner API for PQF added, which allows you to get detailed
3489 error information for bad queries (see yaz/pquery.h).
3491 Fixed bug in ZOOM_record_get for type "database".
3493 Implemented mini iconv library supporting conversions between
3494 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3496 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3498 --- 1.8.9 2002/08/20
3500 Fixed ZOOM C record cache so that preferredRecordSyntax and
3501 elementSetName is used to check for already fetched records.
3503 --- 1.8.8 2002/08/02
3505 Added three members in bend_initrequest structure to facilitate
3506 character set negotiation.
3508 Fixed a bug in frontend server that could cause indefinite
3509 loops under rare conditions.
3511 Revised character set utilities (charneg.h) so that encoding
3512 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3514 For PQF, directive @term <type> sets term type for Scan/Search.
3515 Here <type> is general, string, numeric, null. The term type
3516 is inherited - just like @attr.
3518 New call odr_set_charset that sets character set conversion for
3519 international-strings on a ODR stream. Prototype is:
3520 int odr_set_charset(ODR o, const char *to, const char *from);
3521 The InternationalString is still represented as C string in YAZ
3522 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3523 won't). On the protocol level, you can use any encoding.
3525 Support for UNIX sockets in ZOOM.
3527 Solaris recv sometimes returns errno == ENOENT. It is treated as
3528 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3530 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3531 both client and server. Code by Morten Bogeskov.
3533 --- 1.8.7 2002/05/22
3535 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3536 that they can be used directly from Visual Basic. You must recompile
3537 your windows APP if you're using ZOOM.
3539 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3540 Commands "lang" and "charset" sets language and character set respectively.
3541 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3542 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3544 Attributes from multiple CCL fields may be OR'ed rather than merged
3545 using directive "@field or". Fields are still merged by default -
3546 equivalent to "@field merge".
3548 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3551 Fixed bug in zget for parameter ExtendedServicesResponse.
3555 --- 1.8.6 2002/03/25
3557 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3559 Client displays USR.1:SearchResult-1 (hits per term).
3561 Additional Search Info for search in Generic Frontend Server.
3563 Fixed CCL parsing of "field=s".
3565 WIN32 installer - using the excellent NSIS software from nullsoft.
3567 Fixed CCL parsing of "field = - <number>".
3569 Added function yaz_marc_decode that decodes MARC for line mode
3570 display or XML (similar to that used by JZKit).
3572 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3573 Z39.50. But ISO/ILL was, however.
3575 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3576 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3578 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3579 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3581 --- 1.8.5 2002/02/03
3583 New YAZ client features: Command completion and new commands:
3584 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3585 Code provided by Jacob Poulsen.
3587 New call oid_trav, that visits all registered OIDs via callback.
3589 Function ZOOM_record_get now returns const char pointer rather than
3590 void pointer. It saves a lot of type casts.
3592 For YAZ client, command "auth" now allows you to set authentication
3593 in IdPass style. It is enabled when three tokens are given - order
3594 is user, group and password.
3596 Fix memory leaks in MARC record handling for ZOOM.
3598 New option for YAZ client, -k <kilobytes> that sets
3599 maximum record size. Similar to -k option for generic frontend
3600 server and yaz-ztest.
3602 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3604 Prefix query parser reports "fail" when bad attribute set is given.
3606 Fix in MARC decoder. Proximity logging. Fix for attribute set
3607 in scan handler for server. Patches by Shigeru Ishida.
3609 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3612 Configure option --with-openssl=<dir> now works when a directory is
3613 specified. Patch provided by Morten Bogeskov.
3615 New option for YAZ client, -u <auth>, that sets authentication.
3617 ZOOM fix: error information was sometimes "missing", since error
3618 was cleared/reset too when it shouldn't.
3620 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3622 --- 1.8.4 2002/01/04
3624 Scan for ZOOM API. New object ZOOM_scanset. New functions
3625 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3626 ZOOM_scanset_destroy.
3628 New ZOOM function, ZOOM_connection_last_event, that returns type
3629 of last event (such as "receive data", "send data", "apdu received",
3632 New ZOOM option, schema, that specifies schema for retrieval.
3634 New CCL feature. Qualifiers can be aliases for one or more
3635 other qualifiers (if more than one is given, OR is used).
3637 ZOOM uses named result sets if target supports it.
3639 Two new YAZ client commands: . (dot, which sources a script of YAZ
3640 client commands), and ! (to execute shell command.). Implemented
3643 Working on Debian packages.
3645 --- 1.8.3 2001/11/19
3647 YAZ client enables named result sets only if target supports it.
3649 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3651 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3652 with key="host" to get same result.
3654 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3655 Function Z3950_resultset_record(s) returns references to records
3656 "owned" by resultset. To become owner use Z3950_record_clone.
3658 Function z_ext_record handles Extended Services. Thanks to
3661 --- 1.8.2 2001/11/12
3663 CCL Parser fix: ignore token comma when dealing with and-lists.
3665 Documentation updates for COMSTACK.
3667 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3668 Changed prototype Z3950_records. For some functions, int parameters
3669 were changed to size_t.
3671 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3674 New MARC decode/display function, marc_display_exl, which properly rejects
3675 non-ISO2709 records. YAZ client uses it.
3677 --- 1.8.1 2001/10/29
3679 Fix bug: local attribute set wasn't set correctly in PQF strings.
3683 * Old Z39.50 codecs no longer supported.
3685 Added ZOOM C binding. See http://zoom.z3950.org/
3687 Renamed states for COMSTACKs to avoid confusion with events.
3689 Implemented cs_look and proper cs_rcvconnect.
3691 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3693 Configure detects POSIX threads on OpenBSD.
3695 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3696 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3698 When error is returned from present handler, non-surrogate diagnostic
3699 is returned in present response (and fetch handler is no longer called).
3701 * Minor adjustments to pquery parser (PQF). Token characters may be
3702 escaped by using backslash (C-style).
3704 PQF parser allows string attribute values to be specified. For @attr,
3705 non-numeric characters after the equal-sign are treated as strings
3706 (e.g. @attr 9=title).
3708 CCL trunction character may be defined (@truncation in file)
3710 * function zget_ExtendedServicesRequest sets waitAction to
3711 waitIfPossible (was wait).
3713 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3716 CCL operator names may be set in field definition files (CCL_bibset).
3717 See ccl/bib1 for an example.
3719 Fixes in ASN.1 compiler for C++ compatibility.
3721 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3722 and "op_or" to avoid conflict with C++.
3724 Fixed problem with GNU readline detection on Redhat 7.0.
3726 Added step-size for Scan backend handler.
3728 Fixed bug that made the frontend server crash when no attribute
3729 set was specified for scan.
3731 Front-end server automatically switches to original working directory
3732 when installed as an NT service. Previously -w had to be specified to
3735 Added extended attributes for retrieval module (data1), so that data1
3736 records carry d1_readXML/SGML attributes. d1_read also supports
3737 null-data rules ( <tag/>)
3739 On UNIX when POSIX threads are available, a separate library libyazthread
3740 is created. Programmers should link with that library and the yaz library
3741 when using threads. The reason for the split was that some applications
3742 on Linux, such as Apache, doesn't work well when using shared objects that
3745 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3746 (or any frontend server) in SSL mode by specifying ssl: followed by
3747 address. Only tested on UNIX.
3749 Added feature for CCL module. Virtual structure s=al or s=ol generates
3750 and-list and or-list respectively instead of phrase search.
3754 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3755 log_mask_str. This was done to avoid name conflicts with other libraries
3756 (such as other PHP extensions).
3758 Added raw OID member for preferred record syntax (request_format_raw)
3759 and returned record syntax (output_format_raw) for backend fetch method.
3761 Config file yaz-config now accepts options so that it returns specific
3762 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3764 Shared library support for UNIX using GNU libtool.
3766 * Modified backend interface. Request/Response struct's replaced by
3767 one read/write C struct. For example bend_fetchrequest and
3768 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3769 Every handler - even search has to be registered in bend_init
3770 handler. This means that the YAZ library no longer refers to
3771 external functions and it makes it possible to make the whole
3772 thing a single DLL/SO.
3774 Added Segment handler for backend server.
3776 Added Zmbol/Zebra administrative functions to YAZ client.
3778 Threaded frontend server on UNIX (when POSIX Threads are available).
3779 Starting the server with option -T enables multi-threading.
3783 Added configure option --enable-comp/disable-comp to control use
3784 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3785 located in sub directory asn.
3787 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3788 in ${exec_prefix}/bin along with the other programs yaz-client and
3791 GNU automake used to maintain makefiles.
3793 Added several OID's.
3795 Changed retrieval module so that we can load records with no abstract
3796 syntax defined. Tagpaths in these records are fully composed of string
3799 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3803 On UNIX, the generated makefile now supports a proper 'make install'.
3804 The prefix can be set via GNU configure to set the install location
3805 (default is /usr/local).
3807 * YAZ programs client and ztest were renamed to yaz-client and
3808 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3809 locations, such as /usr/bin,/usr/local/bin,etc.
3811 * YAZ Header files were moved from include to include/yaz. YAZ Header
3812 files are referred to as include <yaz/log.h> rather than <log.h>.
3813 The YAZ include path (-I ..) is therefore the same as before. Programmers
3814 should update their #include statements or use -Ipath/include/yaz
3815 instead. The main motivation for doing this change is that YAZ header files
3816 can be installed in "standard" locations /usr/include,/usr/local/include
3817 without introducing conflicts, since ALL YAZ header files are stored
3818 in subdirectory yaz (under /usr/include for example).
3820 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3821 rather than project/workspace files. We switched because project files
3822 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3825 Changed name of logging function, logf, to yaz_log, to prevent name
3826 clash with some math-log functions. The YAZ header log.h defines logf
3827 to yaz_log (#define) so there should be no incompatibilities by this
3830 Added bend_start/bend_stop handlers for server. These handler are
3831 called on start/stop of server. For windows they are called whenever
3832 a service is started/stopped.
3834 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3835 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3836 in util/yc.tcl. The auto-generated C code structures are, in a few
3837 cases, incompatible with the old decoders. There are differences in the
3838 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3839 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3840 The preprocessor variable ASN_COMPILED is defined when the compiled
3841 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3842 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3843 wish to use the old encoders/decoders you can specify --disable-yc
3846 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3847 version so that it supports both new - and old version of DB Update
3849 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3850 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3851 change. The name parameter can be set to 0 in which no name is specified
3852 for the construction. The macros odr_implicit and odr_explicit sets name
3853 parameter to zero for the construction involved. New macros
3854 odr_implicit_tag and odr_explicit_tag are similar to the others,
3855 except that a name parameter is added. For programmers' that don't use
3856 ODR they probably only need to change the call to z_APDU and z_External.
3858 Added access control facility by interfacing the TCP wrapper library.
3859 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3860 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3861 name of the daemon and enables the access control as specified in
3862 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3864 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3865 den Dool <H.M.vdnDool@kub.nl>.
3867 Added reference ID parameter to most functions in server API - refer
3868 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3870 Changed name of ccl library to libccl.a (was ccl.a).
3872 Fixed bug in decoder for Explain (Category TargetInfo).
3874 Added support for GNU readline in client. Thanks to Jacob Poulsen
3875 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3877 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3878 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3879 IMPLEMENTATION! This change was made to the development version before
3880 the ZIG decided to retract the amendment. If any users MUST be
3881 compatible with the original Update definition, PLEASE CONTACT US, and
3882 we will include a separate definition corresponding to the old Update
3883 ES. Note that because of the change to the ASN.1 of the
3884 TaskPackageRecordStructure we cannot define a single structure that
3885 will support both versions.
3887 * Added const modifier to buffer parameter for some ODR/BER encoding
3888 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3889 completeWAIS, odr_dumpBER.
3891 Fixed bug in client.c which caused a crash when a scanResponse didn't
3892 contain positionOfTerm.
3894 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3895 * will cause an error in a client if a non-YAZ target sends both a
3896 * list of Scan entries and non-surrogate diagnostics.
3898 Retrieval module enhancements. Tag sets may be typed in the reference
3899 to it. From the .abs-file the "tagset" directive takes a third optional
3900 integer type for the tag set referenced. From a .tag-file the "include"
3901 directive takes a third optional type as well. The old "type" directive
3902 in the tag set itself is still recognized but acts as the default type
3905 Backend interface change. Individual Scan terms returned from bend_scan
3906 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3907 in include/backend.h.
3909 Retrieval module enhancements. Multiple tag sets and attribute sets may
3910 be specified in abstract syntax specs. Revised the error/warning for
3911 logging messages reported by the retrieval module when reading the
3914 Object Identifier system (oid_..) changed. The API is backwards
3915 compatible but the oid-routines now allocates new OID's when needed.
3916 Raw OID's may be specified in oid_getvalbyname.
3918 YAZ now uses GNU configure to generate Makefile(s).
3920 * Minor changes in some of the member names of DeleteResultSetRequest and
3921 DeleteResultSetResponse. See include/proto.h.
3923 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3924 and added member 'languages' in TargetInfo (which was missing).
3926 Changed the way attribute sets are handled in the retrieval
3927 module. These are now cached, just like the abstract syntaxes
3930 Changed YAZ so that it links with compiled ASN.1.
3932 Added Explain-schema definitions and mapping routines. The following
3933 Explain categories have been implemented: AttributeDetails,
3934 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3936 Fixed minor bug in Windows version of Server Library.
3938 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3940 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3942 Added EXTERNAL: UNIverse Resource Report (non-standard).
3944 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3945 ENUMERATED and SET OF.
3947 * Added 'const' to some of the char pointer arguments for the
3948 functions, data1_read_node, data1_getelementbytagname,
3949 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3952 Fixed bug in data1_insert_taggeddata - the last_child member of
3953 parent wasn't initialised.
3955 * Changed data1_read_record and data1_read_node so that the supplied
3956 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3957 doesn't refer to any parts of the "SGML"-buffer.
3959 Fixed bug in server library (Windows version of statserv_remove).
3961 * Changed code so that it compiles as C++. The type definition
3962 of Odr_fun which is a member of Odr_arm was changed. The result is,
3963 that an explicit typecast is needed for the fun pointer when
3964 using Odr_arm - as in:
3965 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3967 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3969 Implemented the new structured date and time definition as approved
3970 by the ZIG. Added schemaId element to the specificTag in Espec-1
3971 (also approved at the last ZIG). Thanks to RVDM.
3973 Added some Object identifiers (RVDM).
3975 Changed the Update Extended Service (RVDM).
3977 Added command "refid" to client which specifies referenceId for
3978 the following requests.
3980 Implemented extended service handling for server. See ztest.c
3981 for an example as well as backend.h. New handlers are registerd
3982 in the Init handler.
3984 * Changed interface for sort in server.
3986 Added new members to statserv_options_block. It allows a server
3987 to read options from another source than just the command line. Thanks
3988 to Charles Woodfield.
3990 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3991 renamed to zboolean. Some C++ compilers complained about the name.
3993 Minor changes to gils.abs. Added index 's' (sort) on title
3994 and date/time-last-modified.
3996 --- 1.4pl2 1998/1/30
3998 Fixed bug in server library regarding inetd mode (-i). This bug
3999 was introduced by release 1.4.
4001 --- 1.4pl1 1998/1/29
4003 Added sort facility in client and backend server interface.
4005 Fixed problem with dependencies in Makefile(s).
4007 Fixed bugs for encoders/decoders of extended services and
4010 Implemented sub-tree feature for schemas. Sub-trees are
4011 referenced in *.abs-files. See explain.abs for an example
4012 of the use of this feature.
4014 Modified bib1.att; local attributes for ANY didn't include
4015 ANY itself (only affects use of the retrieval module).
4017 Fixed bug in plain SGML reader in function data1_read_node:
4018 tags with prefix "var" was incorrectly interpreted as variants.
4020 Added feature "sub-schemas" to enable references to - and definitions
4021 of - group of elements.
4023 * Removed member parent from type data1_element (in data1.h).
4025 Implemented function odr_nullval() that returns the value of
4028 * Removed member num_children from data1_node (in data1.h).
4030 Made NT service interface part of the server library. The
4031 function statserv_main uses the NT service when required and
4032 calls the statserv_start / statserv_close routines.
4034 Routine zget_SearchRequest and zget_PresentRequest fills
4035 resultSetName/Id member with "default" instead of "Default".
4037 Fixed memory leak in server. Request queue member wasn't freed.
4039 Fixed nmem_exit so that memory is freed.
4043 Revised the CCL parser utility to be thread safe.
4045 Added function, oid_ent_to_oid, to replace the function
4046 oid_getoidbyent, which is not thread safe.
4048 * Added nmem_init and nmem_exit to initialize and release
4049 NMEM resources. Function nmem_init should be called once in the
4050 initial thread before NMEM/ODR is used. statserv.c and client.c
4051 have been changed accordingly. The change was necessary to make
4052 NMEM thread safe. The NMEM memory pool is shared amongst threads
4053 in a process. Unix-based applications will still work fine without
4056 Added NT Services interface for the the Z39.50 (statserv) Server.
4057 Refer to the ztest.c source on the usage.
4059 Windows 95/NT port using MSVC5.0. Project files are included in the
4062 * Defined new 'global' handle for the retrieval (data1) system. The
4063 new handled, data1_handle, describes the state of the data1 system.
4064 This handle is passed as first argument to virtually all
4065 data1 related routines. The functions data1_create and data1_destroy
4066 creates and destroys a data1 handle respectively.
4068 Added ODR encode stream member to all backend request structures
4069 init, search, scan etc. This stream should be used to allocate all
4070 memory used for the response when thread safe operation is needed.
4072 Changed the comstack utility, cs_addstr, to be thread safe. The
4073 returned hostname string returned by the function is now part the
4076 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4077 function. The cs_straddr takes a COMSTACK handle as argument, so this
4078 function must be used after cs_create and before bind/connect.
4079 This function is thread safe.
4081 Moved test server to 'ztest' directory - generic server code still
4082 in 'server' directory.
4084 Made prefix query (pquery.c) utility thread safe.
4086 Added new function modifier YAZ_EXPORT to 'export' public DLL
4087 functions when using windows (see include/yconfig.h).
4089 Added definitions to the OID database (util/oid.c) (RVDM).
4091 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4093 Added call to ccl_rpn_delete in client program.
4095 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4096 release of RPN structure.
4098 Added support for C++, headers uses extern "C" for public definitions.
4099 With input from RVDM.
4101 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4102 Thanks to Ronald van der Meer (RVDM).
4104 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4106 Added support for private extensions to the OID database
4107 (oid_setprivateoids()). Thanks to RVDM.
4109 Added optional, physical ANY (key replication)
4111 Fixed null-reference problem in GRS-1 output filter.
4113 Proximity operator added to Prefix Query Format (PQF).
4115 In test client command "base" accepts multiple databases.
4117 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4121 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4123 Smallish bug-fixes in the new encoders/decoders (explain).
4125 Bug fixed in DeleteRequest.
4127 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4129 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4131 Added SOIF syntax (using private OID for now) to retrieval module and client.
4133 Added Update extended service.
4135 Added SearchResult-1 additional info structure.
4137 Added optional CCL (ISO8777) interpreter as separate module. Available
4140 --- 1.2 1996/6/10 (1st anniversary release)
4142 Added Summary record syntax. Lightly tested.
4144 Added OPAC record syntax. Untested.
4146 Added ResourceReport service encoders/decoders. Untested.
4148 Fixed bug in z_Unit - wrong tagging on unitSystem.
4150 Fixed bug in the DiagRecs decoder.
4152 Added options for max PDU size and session timeout to frontend-server.
4154 Added documentation of query-language parsers and other supporting utilities.
4156 [frontend-server] Added Attribute set to the bend_scanrequest API.
4158 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4159 surrogate diagnostics were generated.
4161 [retrieval] Allow multiple local values for attribute.
4163 [retrieval] Allow multiple attributes per element in .abs files. index type.
4165 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4167 --- 1.1pl2 1996/4/10
4169 Minor changes, mostly specific to Zebra's requirements (retrieval)
4173 Repaired bug in frontend server when running multiple listening
4174 endpoints in dynamic mode.
4176 z_External() now won't break if a known, ASN.1 value comes encapsulated
4177 in an octet-string. The value will pass through unmodified in an Odr_oct.
4179 Added a bit of code to the demo client to decode & display
4180 ASN.1-structured records represented in the octet-aligned branch of
4181 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4183 Added z_ext_getentbyref() to the ASN module. Doc updated.
4185 * Completed the SCAN definition in the ASN module. This may break SCAN
4186 code based on older YAZ-versions at compile-time. The fix is easy -
4189 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4190 under the SCAN definition. Remember to initialize this, server-people.
4192 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4193 that this does not extend to ODR and ASN.
4195 Comstack allows insertion of established socket (primarily for
4196 inetd-operation of servers). Doc updated.
4198 Front-end server can now start from the inetd in TCP mode. Doc
4201 --- 1.0pl4 1996/1/24
4205 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4206 the rank and record number.
4208 Adjustments to the frontend server.
4210 Fixed diagnostic BER dumper. It ignored the file argument.
4214 Various changes to retrieval module.
4216 Changed the union discriminators of the protocol files from enums to
4217 ints paired with #defines.
4219 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4222 *Changed operator in the RPN structure to 'roperator', again to avoid a
4225 Fixed problems in Explain decoders/encoders.
4227 --- 1.0pl2 1995/12/6
4229 Memory bug in log module fixed.
4231 --- 1.0pl1 1995/12/5
4233 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4235 Bug in Explain DatabaseInfo module fixed.
4237 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4241 The shift to v1.0 signals that we now consider the *core* functionality
4242 of YAZ reasonably stable (the core being more or less equivalent to
4243 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4244 tested (Explain not at all - though that will happen soonish).
4246 Minor changes to code to support Windows port.
4248 Various minor changes after we're getting to use GRS-1 & co. more.
4250 Added Espec-1 format.
4252 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4253 of the protocol and it cannot be selected when encoding (maps into 'string'
4254 when decoding). Needed to talk to some servers.
4256 Demo client can request simple element set names.
4258 Added Diagnostic Format encoders/decoders.
4260 Added simple Close handling to frontend server (no hooks for resource
4261 reporting yet), and demonstration client.
4263 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4265 --- 1.0b3 1995/08/24
4267 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4268 handled incorrectly when records were requested in the searchResponse. This
4269 will only affect you if you use the frontend-server.
4271 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4272 Test-client will ask for and print GRS1. Ztest will return dummy records
4275 Added Explain encoders/decoders to the service-level API. Untested.
4277 Added Extended Services: Item Order encoders and decoders to the Service-
4278 level API. Untested. We could use a recent copy of the pertinent bits
4279 of the ILL protocol to add those bits.
4281 Added diagnostic format 1 encoders/decoders to the service-level API.
4284 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4285 odr_cons.c, which causes a more correct output.
4287 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4288 was always set to 0 when no records were requested in the searchRequest.
4290 * Added better external-handling. This shouldn't harm old code that
4291 *encodes* externals. It can break code that looks for a
4292 'single-ASN1-type' representation, since those types that are known
4293 are now decoded immediately. Look at the SUTRS sample code in
4294 seshigh.c and client.c. Documentation updated.
4296 Handling of structured records in bend_fetchresponse. Length -1 marks
4297 structured record, type is deduced from format field.
4299 --- 1.0b2 1995/06/27
4300 Fairly quick maintenance release to add SUTRS support.
4302 Fixed handling of SUTRS records in the demonstration client.
4304 * Added format field to the bend_fetchrequest and bend_fetchresponce
4305 structures of the backend API (frontend server). When the record is
4306 returned, the value of the format field is mapped to an OID. The
4307 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4308 of the record. The special value VAL_NONE in the bend_request means
4309 that no specific format was requested by the client. Documentation
4310 updated accordingly. Test server (ztest) will return a fixed dummy
4311 SUTRS record if your client requests SUTRS.
4313 Documentation updated accordingly.
4315 You can now set external libraries and RANLIB support in the top-level
4319 First public release.
