19 Windows: Bundle VC runtime exe YAZ-848
21 Omit Content-Type for HTTP requests to Solr YAZ-850
25 Fix rpn2cql: structure, relation problem for serverChoice YAZ-849
26 Problem was that for things mapped to cql.serverChoice the relation
27 would sometimes be omitted when it should not. Eg for relation "all".
31 Document zoom extraArgs YAZ-817
33 Fix ZOOM: crash extended services diagnostics YAZ-846
34 The immediate fix is to prevent ZOOM_set_dset_error from removing
35 current task from connection. This, however, has been assumed in a
36 number of places so this fix is rather large unfortunately.
40 Make yaz_log_reopen async-signal YAZ-845
41 Fixes potential dead-lock issue with YAZ_DAEMON_LOG_REOPEN flags for
46 CCL: new feature s=spl (split-list) that splits terms in a search into
47 sub-phrases of all sizes (from 1 up to the number of terms) with order
48 preserved. For 3 terms the CCL search
51 @or @or @or @and @and a b c @and "a b" c @and a "b c" "a b c"
53 Solr: don't set defType=lucene in URLs if extraArgs already defines it.
57 Add lock/unlock for YAZ log writes YAZ-843
61 Fix incorrect parsing of URLs @:9999/somebase&url=http://some.host YAZ-842
65 yaz-client: deal with excess bytes HTTPS case YAZ-833
67 ZOOM C: deal with excess bytes HTTPS case YAZ-833
69 Allow Windows installer for PATH to be updated YAZ-841
71 Add Ubuntu Vivid 15.04 to list of Deb's to built
75 Allow Content-Type application/sru+xml YAZ-840
77 New yaz_xml_get_prop utility YAZ-839
79 Fix zebrasrv [warn] ir_session (exception) YAZ-838
81 Document itemorder-setname and list all ILL options
85 Extend get_org_info (snippets) to return original string YAZ-836
86 Two new functions have appeared: icu_chain_get_org_info2 and
87 icu_iter_get_org_info2 with a 4th parameter being a pointer
88 to the original string.
90 Fix tcpip.c compilation failure on VC9 YAZ-835
92 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
93 The icu_iter_get_org_info returns information based on string
94 as it appears on tokenize step.
98 Deal with excess bytes in HTTP response for keepalive YAZ-830
100 Refactor ssl_put and tcpip_put to one function YAZ-832
102 Refactor ssl_get and tcpip_get to one function YAZ-831
104 Fix SEGV yaz-client for HTTP decoding error YAZ-829
106 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
108 --- 5.10.1 2015/03/03
110 Fix test_sru.sh fails in pazpar2 YAZ-826
111 Unfortunately a regression occurred with YAZ 5.10.0 that would make
112 Pazpar2 fail for HTTP connections.
114 --- 5.10.0 2015/03/03
116 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
117 Introduce cs_create_host2 which returns if connection should be
118 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
119 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
121 Fix http proxy fails with yaz-client YAZ-824
125 Fix 0 ptr reference for OPAC records from XML YAZ-822
129 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
133 record conv: 'select' return org record if no x-path match YAZ-814
135 retrieval: pick matched element-set rule YAZ-813
137 Fix crash in record conv rule 'select' YAZ-812
141 record_conv: selection by X-Path YAZ-811
142 That's a new step in record conversion system (<select path=".."/>)
144 Document record render parameters for ZOOM - including base64
148 Fix application/x-www-form-urlencoded + empty YAZ-810
149 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
150 and empty content was supplied.
152 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
154 Fail hard if Bison is not found and is needed YAZ-808
158 Enable YAZ backtrace for programs YAZ-802
160 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
161 Libxml2 2.9.2, Libxslt 1.1.28.
163 Fix daemon: parent process stops before child YAZ-806
164 Try to fix the situation where parent process stops before
165 child has acknowledged it .. SIGUSR2 back!
167 daemon: log message when keepalive stops.
171 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
172 would make yaz-marcdump crash when from-character set was issued.
176 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
177 New function yaz_enable_panic_backtrace which enables backtrace
178 handler for current process. The handler will call backtrace always,
179 then gdb to provide as much detail as possible.
183 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
184 and ZOOM record render will inspect leader 9 and switch to UTF-8
185 (Unicode) if that holds 'a'. This changes behavior, but is considered
186 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
188 Fix cs_put may reconnect if send fails. YAZ-798
192 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
196 Extended comstack with outgoing IP YAZ-795.
197 For cs_create_host + cs_create_host_proxy the vhost may be followed
198 by a outgoing host/IP. Separator is blank.
202 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
203 linker error with yazpp on Windows.
207 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
209 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
211 0 ptr reference in handling Solr response with error YAZ-791
213 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
215 Fix documentation about --installa option YAZ-788
219 daemon: properly report when receiving SIGUSR2 from child YAZ-785
223 xmalloc: throw assert for clearly invalid calls to malloc and
224 improve diagnostics YAZ-783 YAZ-784
228 Stop building debs for Ubuntu raring, quantal, oneiric.
230 CCL YAZ-781: for multiple use attributes in a specification the
231 generated RPN will perform @or on each term.
232 For spec: term u=31 u=1016
233 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
235 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
237 CCL YAZ-779: combo qualifier should allow for forward references
239 Fix buildconf.sh, automake too old on centos5 YAZ-778
240 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
241 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
242 accepts it without a warning.
246 GFS: client_query_charset conversion YAZ-777
247 This is a feature for Z39.50 clients that sends queries that are not
248 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
249 encoding given to UTF-8.
251 Echoed SRU arguments support YAZ-776
252 This is achieved with new function yaz_srw_get_pdu_e.
254 ZOOM: expire times set for redis/memcached YAZ-772
255 For both redis and memcached option --expire=seconds sets expire
256 time for a result-set/search. Default time is 600 seconds (10 minutes).
260 No [rest of output is omitted] limit for yaz_log YAZ-774
262 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
264 For ICU testing, pass -o to yaz-icu. This will test the
265 icu_iter_get_org_info function.
267 Fix null ptr reference for freeReplyObject YAZ-773
271 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
273 RPM: do not build with libmemcached support. The libmemcached library
274 on CentOS 5/6 does not work reliably for us (redis to the rescue).
276 configure: only allow libmemcached version 0.40 or later. That's the version
277 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
278 that's not an option, consider redis.
282 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
284 Fix zoom+memcached: present request out of range YAZ-767
288 CCL: add new qualifier r=omiteq which will omit relation=equals
289 for ordered relations. This should be used in combination with either
292 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
294 Solr: simplify yaz_solr_decode_response
296 Solr: use different local var for string manipulation
298 Solr: Get rid of hardcoded limit of extra_args
300 Solr: encode lucene query type YAZ-736
301 Make sure the queries are treated as traditional "lucene", because that's
304 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
308 Build packages for Ubuntu Trusty Tahr 14.04 LTS
310 wrbuf_cstr: fix off by one error.
312 wrbuf_buf: make it always return non-NULL
313 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
317 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
319 zoomsh: offer option -a apdulog
320 As we're used to from yaz-client and GFS based servers.
322 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
323 existing setting apdulog takes effect.
325 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
330 Add re-entrant CQL/Solr/RPN query conversion functions.
331 The re-entrant functions are: cql_transform_r,
332 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
333 These have same functionality as cql_transform,
334 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
335 return the additional infomration as WRBUF to make them re-entrant.
337 Remove CQL to Solr conversion and base solr_transform_t on
338 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
339 data structure as cql_transform_t.
341 cql2pqf utility allows RPN to Solr conversion
343 Fix assert in ZOOM when http connect fails YAZ-757
345 --- 5.0.22 2014/04/09
347 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
349 wrbuf_cstr: make it thread safe YAZ-753
351 yaz_log_init_file may take fd=<no> to open log file at the FD given.
353 --- 5.0.21 2014/03/21
355 Offer new utility function zget_AttributeList_use_string.
357 New conversion step, solrmarc, for record conversion module.
359 --- 5.0.20 2014/03/13
361 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
362 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
365 --- 5.0.19 2014/03/10
367 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
368 The standalone ZOOM sort was completely broken since 5.0.13.
370 ZOOM: generate event Connect rather than None for partial connect
371 (in fact getaddrinfo resolving).
373 ZOOM: only supply clientIP for InitRequest. Rather than for all
376 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
378 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
379 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
380 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
382 New "Facets" section in the documentation.
384 --- 5.0.18 2014/02/27
386 Call exsltRegisterAll in yaz_init_globals, so that all applications
387 using YAZ will have EXSLT things enabled.
389 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
391 Update various URLs to the re-organized SRU pages at LoC.
393 --- 5.0.17 2014/02/26
395 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
396 introduced in 5.0.12.
398 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
399 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
400 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
403 --- 5.0.16 2014/02/25
405 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
407 --- 5.0.15 2014/02/24
409 Fix gcrypt not properly initialized YAZ-740.
411 --- 5.0.14 2014/02/19
413 Describe memcached option for ZOOM.
415 ZOOM: throw present request out of range again YAZ-739
416 Was removed in YAZ 5.0.13.
418 --- 5.0.13 2014/02/18
420 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
421 with localtime_r when threads + fork is used (such as Metaproxy).
423 yaz-config: quote some RHS values (that might include blanks)
425 zoomsh: shows SearchResult-1
427 zoomsh: sortby command
429 zoomsh: use proper list of connections and result sets YAZ-725
431 Avoid yaz_log in sigterm handler for GFS YAZ-737
432 Logging is still performed, but outside sig handler.
434 New ZOOM C feature: result-set caching with memcached. Example:
435 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
437 Remove SSL via OpenSSL support YAZ-732
438 Also deprecate two functions from comstack that aren't working with
439 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
441 Revert "Bison: use %name-prefix directive rather than -p option"
443 --- 5.0.12 2014/01/22
445 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
447 SRU GET/Solr base URLs may hold additional ?args YAZ-729
448 ZOOM option extraArgs already does this, though. It seems useful
449 when dealing with Solr targets to limit by filter, eg.
450 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
452 Remove #fragment for HTTP request encoding YAZ-730
454 Doc: Update list of DLLs/LIBs
456 Doc: update href link to Unix utils and Git.
458 --- 5.0.11 2014/01/15
460 ZOOM: fix "lost connection" problem with servers that uses both squid
461 and another proxy behind it that returns Location headers with relative
464 zoomsh: do not use readline for stdin (no tty) YAZ-724
465 Just use fgets in that case. If the user hits Ctrl-D a new-line
468 zoomsh: empty command ignored YAZ-723
469 rather than performing exit of zoomsh.
471 yaz-url utility offers option -v to enable verbose mode.
473 yaz_url uses yaz_check_location and offers verbose mode.
475 Add new function yaz_check_location.
476 This function gets an absolute URI from Location (HTTP redirect).
478 cookie API: introduce yaz_cookies_reset
480 Update cql.y for newer bison YAZ-720
481 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
482 longer supported. Instead one must use %lex-param and %parse-param .
484 --- 5.0.10 2014/01/09
486 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
489 rpn2solr: support truncation left(2), left&right(3) YAZ-718
491 Mention SRU version 2.0 in yaz-client man page.
495 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
500 Make cs_parse_host public.A
502 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
503 introduced in YAZ 5.0.6.
507 Fix buffer corruption for yaz-ztest record fetch.
511 Allow yaz-ztest to return user-defined records (one record per file).
512 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
514 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
515 Use the stream write instead of odr_printf which has a 4K tmp buffer.
517 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
521 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
522 can read and write this format. For record format JSON, yaz-ztest returns
523 MARC-in-JSON records.
525 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
526 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
530 Improve error reporting for ICU chains YAZ-707
531 Report config element+rule when ICU status is "failure".
533 ZOOM: stop fetching if present response has no records YAZ-710
534 Some targets return less records than their hit count would suggest.
535 This prevents ZOOM from continuing to fetch records if any present
536 response has 0 records in the response.
538 Ensure that GFS calls exit if any listener fails YAZ-710
539 Before, if XML config was in use, it would start the default
544 yaz-ztest: -V shows version (like yaz-client -V)
546 New iconv encoding: danmarc YAZ-692
548 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
550 daemon: only wait for immediate child rather than all children. YAZ-704
552 yaz-client: fix setting of SRU record schema. If scheme was unset, it
553 could lead to invalid memory reference.
557 yaz-ztest returns schema for MARCXML test records. SRU require that
558 recordSchema for records.
560 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
561 instead of non-surrogate diagnostic. This is a per-record failure.
563 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
564 may refer to multiple listeners now. Attribute listenref is a comma separated
567 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
568 option is given for GFS, the dirname of filename (for -f) is used
569 as prefix for options such as cql2rpn, ccl2rpn, etc.
571 Content-Type charset fixes YAZ-701 . Do not inspect charset in
572 Content-Type header for SOAP when decoding SRU. The payload (XML)
573 itself tells what encoding it is. In response, never supply encoding
574 in Content-Type. The response payload (XML) tells what it is (with no
575 encoding in XML it's UTF-8).
577 HTTP decoding: allow blanks in URL paths YAZ-700
581 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
582 and facets. Ensure recordData and recordSchema are always present in
583 record element, because they are required.
585 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
588 Simplify in a lot of places using odr_strdupn.
590 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
594 Increase various buffers in GFS's statserv_options_block
595 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
596 This change makes many type-casts redundant, and, thus simplifies code.
598 Remove last bits of WAIS support.
600 Remove member 'size' from Odr_oct.
602 Slim down the public part of 'struct odr'. Most elements are not part
603 of struct Odr_private.
605 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
606 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
607 In particular facets are supported in both client - and server side.
608 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
609 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
610 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
611 both request/response). This is what a search handler in the GFS
612 will see (regardless of whether operating in SRU mode or Z39.50).
614 Changes to the srw.h (SRU/Solr) definitions include:
615 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
616 (char*), which replace union query and query_type (int). This is because
617 SRU 2.0 supports a queryType parameter. This also means that, to carry
618 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
619 x-pquery=PQFstring (extention parameter). The extension parameter
621 - New element, packing, that has information about SRU
622 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
624 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
626 New element, packing, in Z_SRW_explainRequest.
628 New elements in Z_SRW_scanRequest, queryType and scanClause.
629 These replace query_type and scanClase untion. This is similar to what
632 --- 4.2.69 2013/10/01
634 GFS: log when closing down - at least SIGTERM YAZ-684
635 Also change formatting WRT PID logging a bit.
637 Improve display of MARC records with multi-byte subfield IDs YAZ-695
638 In some rare cases subfield identifiers are multi-byte characters.
639 This will try to deterime length of those and split accordingly.
640 This affects display in line mode as MARCXML/MarcXchange. The encoding
641 of ISO2709 is the same.
643 Change inp argument to const for yaz_read_UTF8_char.
645 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
647 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
649 Better check of marc leader info YAZ-691
650 Problem is that some systems generate MARCXML/MarcXchange with
651 funny headers. These will not work if encoded as ISO2709.
652 Some tests produce new output, due to updated warning messages
654 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
656 yaz-client: display MAB records YAZ-689.
657 Thanks for Heiko Jansen for this patch.
659 New utility z_get_HTTP_Response_server which allows both HTTP server name
660 and HTTP server URL to be given in response.
662 Debian: do not depend on obs tcl8.3.
664 Debian: do not depend on obs libicu36-dev.
666 --- 4.2.68 2013/09/23
668 GFS: pass additionalSearchInfo to search memeber search_input if
669 given. Otherwise pass otherInfo. Request for facets and other search
670 related things will be passed there in future versions of YAZ.
672 New ZOOM setting, authenticationMode, which allows authentication
673 paramters to be encoded in the URL rather than via HTTP Basic auth.
676 rpn2solr: fix nested AND/OR handling. YAZ-685
678 Add comparison routines for some Z-types, such as NamePlusRecord,
679 RPNQuery, Query, RecordComposition and OtherInformation.
681 --- 4.2.67 2013/09/19
683 Don't decode MAB as MARC. Just like we don't attempt to decode
684 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
686 CCL: allow quoted terms for date ranges. YAZ-681
688 Introduce ccl_parser_qual_search. This function makes old function
689 ccl_qual_search, from YAZ 2, available again.
691 Add yaz_facet_list_to_wrbuf. YAZ-683
693 --- 4.2.66 2013/09/11
695 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
696 schema was given for search. YAZ-675
698 Add Solr date range searches. YAZ-621
700 --- 4.2.65 2013/08/22
702 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
704 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
706 ISO2709/MARC parse most octet aligned records; not just those that
707 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
708 MARC parse more records instead of just dumping as is. YAZ-670
710 ZOOM: proper caching for variations of record schema. YAZ-671
712 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
714 --- 4.2.63 2013/07/17
718 --- 4.2.62 2013/07/11
720 New utility z_get_HTTP_Response_details - an extended version of
723 New utility yaz_url_get_error which returns error message of last
724 failed yaz_url_exec call.
726 yaz-url and url functions: allow max HTTP redirects to be controlled.
728 New functions yaz_file_glob2, yaz_xml_include_glob.
729 These functions takes a flags parameter, which, for now only controls
730 whether to fail inclusion of a non-existing file (without glob
731 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
733 --- 4.2.61 2013/06/20
735 For MARC XML parsing, allow record without leader. A fake/default leader
736 is inserted and a warning is tagged with the record.
738 ICU: fix leak in in icu_iter_get_org_info.
740 --- 4.2.60 2013/06/14
742 ICU: fix bug in icu_iter_get_org_info (un-init variable).
744 --- 4.2.59 2013/06/11
746 Implement z_HTTP_header_remove.
748 --- 4.2.58 2013/06/11
750 ICU: Disallow 0 ptrs for some ICU string utilities.
752 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
753 returns original tokens (before normalization).
755 CCL: avoid z39.58/regex truncation when not needed. Apply only the
756 conversion of those masks, when absolutely necessary.
758 CCL: configurable masking character - @mask. Default masking character
761 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
762 full response anyway, so a Transfer-Encoding header will obstruct the
765 --- 4.2.57 2013/05/15
767 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
768 picking a socket. Problem is that some systems has IPV6 support, but
769 we can't create sockets for them, so we pick AF_UNSPEC first.
771 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
772 use content_len to determine resulting Content-Length in HTTP response
773 and NOT Content-Length supplied in headers by user.
775 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
776 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
778 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
781 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
782 with big endian and unsigned char (by default).
784 --- 4.2.56 2013/04/26
786 Fix yaz-client connect (crash in 4.2.55).
788 --- 4.2.55 2013/04/26
790 Fix proxy/host problem for ZOOM that could occur if unix sockets
793 New Debian package libyaz4-dbg.
795 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
796 differently in tcpip_close.
798 --- 4.2.54 2013/04/17
800 Windows installer of YAZ includes YAZ4J as a component.
802 CQL: allow "extra terms" again, by default. Thus, the CQL parser
803 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
804 and earlier. CQL parser may operate in strict mode where queries
805 not conforming to the standard BNF are rejected (syntax error).
806 Whether the CQL parser operates in strict mode is controlled with
807 cql_parser_strict . Strict mode enabled with option -S for utilities
808 cql2pqf and cql2xcql .
810 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
812 --- 4.2.53 2013/04/10
814 New charset, MARC-8c, which is like MARC-8 but allows control characters
815 0x01 through 0x1F, except ESC to be passed through verbatim.
817 Fix a problem with duplicate sub field character in MARC output. Problem
818 happened only when output was MARC-8 encoded.
820 --- 4.2.52 2013/04/03
822 yaz-ztest: Use hash for fake hit count. Before, random number was used.
823 This is problematic for unit tests using yaz-ztest. This patch also makes
824 a hash for CQL queries. For RPN, any term with a leading digit will be
825 treated as pseudu hit count (to force any particular hit count by a client).
827 yaz-ztest: return unique MARC dummy records. Beyond record offset
828 24, the author surname is patched with offset to make all records
831 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
832 on system wide default (/proc/sys/net/ipv6/bindv6only).
833 @4 binds to IPV4 only. @6 binds to IPV6 only.
835 Update CQL API documentation a bit
837 CQL: don't accept extra terms for queries. Makes the CQL parser
838 stricly conformant to the standard.
840 --- 4.2.51 2013/02/12
842 GFS: scan handler gets extra_args from request and may return extra
843 response data . That's for SRU only.
845 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
847 --- 4.2.50 2013/01/30
849 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
851 OPACXML: sync spelling of availabilityDate in XML to that of Schema
852 opaxxml.xsd. The schema had the correct spelling of this member always.
853 The ASN.1 was mis-spelled and still is (API change) - we are
854 not changing this. However, the OPAC to XML conversion had yet
857 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
860 New function, z_ext_record_oid_nmem, which is similar to
861 z_ext_record_oid but takes NMEM rather than ODR
863 --- 4.2.49 2013/01/18
865 ICU: New conversion element 'join' which joins tokens into one
866 with a custom character given by rule attribute.
868 --- 4.2.48 2013/01/10
870 New GFS search member: present_number. This is a hint to the
871 search handler how many records are going to be fetched immediately
872 following search. There's no guarantee that it's going to be the case,
873 since it depends on hit count (for Z39.50 piggyback) and whether errors
876 Make a few functions static (private). The functions getbyte_stream,
877 ungetbyte_stream and yaz_gets are now private. They were never declared
880 yaz-marcdump: exit(5) for serious decoding errors
882 ISO2709 decoding: be more picky WRT header
884 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
885 was only used as to indicate that next-result-set-position should be
887 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
888 Based on patch from Ashley Sanders.
890 Make some functions static/private in PQF parsing. Those functions were
891 never declared in a public header and so should not be in use by
892 applications based on YAZ.
894 --- 4.2.47 2012/11/23
896 ZOOM: special options to control APDU logging.
897 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
898 logging of APDUs until "saveAPDU" option is set again. If logging is
899 already enabled the effect is that current APDU buffer is cleared.
900 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
901 logging (default behavior on new connection).
902 The APDUs sent/received can be obtained by using
903 Using ZOOM_connection_option_get(c, "APDU") or
904 ZOOM_connection_option_getl(c, "APDU", &l).
906 GFS: relay implementation_version from backend
907 From 3.0.40 and later, implementation_version from backend was
908 not used in init response at all.
910 --- 4.2.46 2012/11/15
912 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
913 mode at all. Probably never did.
915 Make a new version of ztest.pem that, at least, is not expired.
917 --- 4.2.45 2012/11/13
919 Fix description of CCL directive 'case'.
921 More tight checking of form arguments (yaz_uri_to_array). Makes
922 YAZ better at rejecting big and/or bad POSTs.
924 SRU decoding does not report more than up to 10 invalid arguments.
926 rpn2cql: less quotes in generated terms. Semantics unchanged, but
927 it's prettier this way.
929 --- 4.2.44 2012/10/25
931 New utility yaz_decode_init_diag. Defined in proto.h.
933 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
934 given for unix local socket.
935 The COMSTACK string for doing so is:
938 unix:/myfile:tcp:localhost:9999/mybase
939 unix:/myfile:localhost:9999/mybase
940 unix:/myfile:http://fakehost/mybase
942 debian: Use dpkg-buildflags in build process.
944 --- 4.2.43 2012/10/19
946 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
947 global's SRU service uses a recordPosition scheme starting from zero.
948 First record's position should be one
949 according to the standard.
951 --- 4.2.42 2012/10/18
953 Allow more namespaces for SRU. This is to allow, for example, an
954 incorrect namespace returned from server
955 http://services.igi-global.com/sru .
957 Minor fixes for compilation on Windows.
959 --- 4.2.41 2012/10/11
961 daemon: log total number of bad signals from child on stop so that it
962 is more easy to spot problems with child worker processes.
964 retrieval: empty backend name attribute omits element set
965 from being used in retrieval.
967 --- 4.2.40 2012/10/04
969 Implement Solr sort strategy "solr", similar to sru11 sorting.
970 This will implement the correct parameters on Solr requst to do
973 --- 4.2.39 2012/09/28
975 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
978 MARC: Extra/missing indicator handled for MARCXML.
979 The indicator length is given in header and is the same for the
980 whole record. If attributes ind1, ind2 are missing, then content
981 character defaults to blank. Extra indicator attributes (beyond)
982 indicator length are treated as an error.
984 Reformat: delete trailing whitespace
986 --- 4.2.38 2012/09/17
988 MARC: fix non-ASCII characters for leader. This is to ensure we can
989 generate XML in UTF-8.
991 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
992 in one node with structure word.
994 --- 4.2.37 2012/09/04
996 yaz-json-parse: JSON output may be pretty printed by using option
999 Increase default value of max message for Z39.50 Init for GFS, ZOOM
1000 and yaz-client. Old value was 1 MB. New value is 64 MB.
1002 --- 4.2.36 2012/08/22
1004 yaz-client: don't display bogus records from SRU servers. Some SRU servers
1005 return more records than given by *maximumRecords*. Skipping those in
1008 record_render: simplify buffer return handling and fix at least one bad
1009 memory reference, that broke the test_embed_record sometimes.
1011 Allow http://user:pass@host notation for yaz_url_exec.
1013 zoomsh: allow shell command to be executed. Via the system(3) call.
1015 yaz_poll: Allow num_fds == 0
1017 yaz-client: fix bad encoding of "itemorder item". The itemorder
1018 item <no> - command forgot to use length of encoded Item Request
1019 package. Error present since YAZ 3.
1021 yaz-ztest: fix bad usage of session handle. Bug was introduced when
1022 result sets were saved (271a9c83).
1024 SRU recordPacking: guess record packing in response rather than looking
1025 at the recordPacking element which, OF COURSE, changed semantics in SRU
1028 Decode SRU 2.0 responses. The official namespace for responses, according
1029 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
1030 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
1031 nature.com's server, however, usee namespace
1032 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
1033 we are now using a glob-expr to match up the namespace. ZOOM C and
1034 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
1035 I can not find a single real example showing the "real" namespace in
1036 the documentation from OASIS. The namespace for requests is different
1037 from responses, but this is not added to YAZ yet, when we don't encode
1040 --- 4.2.35 2012/06/26
1042 zoom/record_render: add support for Base64 decoding fo MARC records
1043 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1044 which will decode base64 + ISO2709 marc-8 encoded material from text node
1047 --- 4.2.34 2012/06/07
1049 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1050 and ZOOM_resultset_facets_names.
1052 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1055 Change APDU dump printing to avoid long leading blanks. For levels 16
1056 or larger the level is shown and the indentation is truncated but
1057 recursed with modula 8. This makes it still reasonable easy to read
1058 - even for nested BER dumps.
1060 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1061 return 0 (incomplete package) in case where the BER package was
1062 considered too nested (return value of -2).
1064 dumpber: lines of level 15 are not indented further. Two spaces per
1065 indentation; indentation 15 or more is indented to a fixed indentation
1066 and augmented with a level=<no> indication.
1068 zoomsh: increase max size of command+args
1070 GFS: No limit in RPN buf size in CQL to RPN conversion.
1072 --- 4.2.33 2012/05/09
1074 New function for daemon utility, yaz_daemon_stop .
1076 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1078 --- 4.2.32 2012/04/25
1080 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1081 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1083 --- 4.2.31 2012/04/23
1085 YAZ daemon utility relays SIGUSR1 to child process.
1087 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1088 would result in en empty database list - which in turn would result in
1089 encoding failure for search.
1091 Fix reading beyond string in yaz_sort_spec.
1093 --- 4.2.30 2012/04/11
1095 Add two new SRU diagnostics:
1096 236: Access to specified database denied
1097 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1099 Document the very useful ZOOM-C option "apdulog".
1101 CQL to RPN: term may be passed through verbatim. This is enabled with
1102 truncation.cql . The assumption being that the term is already CQL.
1104 --- 4.2.29 2012/03/20
1106 record_conv: leader spec may be given for marc element.
1107 The leader spec is given as attribute leaderspec for element marc.
1108 For example to convert a MARC21 record from MARC-8 to UTF-8:
1109 <marc inputformat="marc" outputformat="marc"
1110 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1112 record_conv: allow user-XSLT params. For example:
1113 <xslt stylesheet="MARC21slim2DC.xsl">
1114 <param name="myparameter" value="myvalue"/>
1115 <param name="otherparameter" value="othervalue"/>
1118 record_conv: fix error handling for missing marc charsets.
1120 CQL: fix extra terms in wrong order.
1122 --- 4.2.28 2012/03/06
1124 record_conv: modify new API for conversion types. The conversion types
1125 may be passed in new functions yaz_record_conv_configure_t and
1126 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1128 Avoid mixed statement/variable declare; fixes compilation with Visual
1131 --- 4.2.27 2012/02/28
1133 Add non-standard SRU diagnostic: 235: "Database does not exist".
1134 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1135 Update SRU to Bib-1 diagnostic maps accordingly.
1137 CCL: add two new diagnostics for unsupported masking. The new
1138 diagnostics are: "Embedded truncation not supported" and
1139 "Single charcacter mask not supported".
1141 --- 4.2.26 2012/02/23
1143 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1145 --- 4.2.25 2012/01/11
1147 Build YAZ for Ubuntu Oneiric.
1149 CCL: allow parantheses for proximity operands. For example CCL query
1150 (a) % (b) is now allowed.
1152 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1153 marked dead, rather then being destroyed. If not, the session memory is
1154 being free'd before the search/scan handler is finished. Also destroy
1155 'request' memory in request_release rather than in various places,
1156 which resulted in leaks from time to time.
1158 --- 4.2.24 2011/12/21
1160 cql_sortby_to_sortkeys: honor sort prefix.
1162 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1163 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1164 The rpn2cql family of functions now always returns quoted CQL terms.
1166 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1168 --- 4.2.23 2011/12/15
1170 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1171 sequence is treated as one. For example, &&a=b&&&c& is identical to
1174 --- 4.2.22 2011/12/05
1176 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1177 APDUs for a connection to a WRBUF.
1179 --- 4.2.21 2011/11/23
1181 Fix cql_sortby_to_sortkeys. Completely broken before.
1183 Make CCL's @truncation work again.
1185 --- 4.2.20 2011/11/09
1187 New ZOOM connection setting: tproxy. It's like proxy, but does not
1188 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1189 to set resolved address + port for a connection outside ZOOM itself.
1191 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1193 --- 4.2.19 2011/11/07
1195 Fix uninitialized variable in Solr spell support (could cause SEGV
1196 for SRU response decoding).
1198 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1199 back-end's addinfo through into the ZOOM response addinfo.
1201 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1202 they are separated by a colon and a space rather than simply
1205 --- 4.2.18 2011/10/28
1207 Add support for Solr spell-checking/suggestions through ZOOM.
1208 If a Solr target has been configured correctly for spelling-checking
1209 and suggestions, these will now be returned on the ResultSet option
1210 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1212 --- 4.2.17 2011/09/28
1214 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1215 with a flag whether to substitute escape sequences or not.
1217 --- 4.2.16 2011/09/22
1219 Fix nmem_strsplit_escape to substitute escape char properly.
1221 New option for zoomsh -e , which makes it abort on first error and
1222 return process exit code to indicate success/failure.
1224 YAZ options utility supports special option -- which makes all it treat
1225 all following arguments as non-options.
1227 --- 4.2.15 2011/09/16
1229 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1230 searched if absolute filename is given.
1232 Fix conv_xslt() error-reporting when stylesheet is not found.
1233 (The value of fullpath is meaningless in this situation.)
1235 --- 4.2.14 2011/09/07
1237 Fix problem in CQL sort node creation: un-initialized memory.
1239 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1240 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1241 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1244 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1245 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1247 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1248 will make it possible to use both single-character mask (#) and wildcard (?)
1249 in CCL . Throw diagnostic for left truncation because that is not supported
1252 --- 4.2.13 2011/09/01
1254 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1255 cases using escapes (\-sequences) and masking.
1257 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1258 would result in a read one byte beyond string.
1260 rpn2ccl may use Z39.50 masking for terms (t=z).
1262 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1264 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1265 not --cppflags (which seeems like an error in icu-config).
1267 --- 4.2.12 2011/08/27 RPM package only
1269 cql2ccl: fix conversion of terms: operator characters were not
1272 --- 4.2.11 2011/08/25 RPM package only
1274 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1275 CCL parser will map both # and ? to their regular expression
1276 quivalents (. and .*).
1278 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1279 of reserved CQL characters.
1281 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1282 is, so that they are passed through.
1284 --- 4.2.10 2011/08/24
1286 ZOOM SRU mode: more aggressive re-connect.
1288 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1289 made available as a utility function, declared in <yaz/logrpn.h>
1291 rpn2cql_structure() supports proximity nodes (except that the Type-1
1292 proximity node's "exclusion" binary is ignored, as there is no way to
1293 express that in CQL). Fixes bug #4564.
1295 --- 4.2.9 2011/08/18
1297 Fix SEGV that could occur if set command of zoomsh was given without
1298 value (2nd argument).
1300 Fix SEGV that could occur if unsupported transport was given for
1301 COMSTACK - say https (when SSL was unavailable).
1303 Build yaz-url on Windows too.
1305 --- 4.2.8 2011/08/11
1307 New utility to get web content. Header is url.h. A command line tool
1308 yaz-url is part of the distribution and packages.
1310 Fixes for SSL COMSTACK (when gnutls is in use).
1312 New functions yaz_base64{encode,decode}. Header is base64.h.
1314 --- 4.2.7 2011/08/03
1316 ZOOM C includes HTTP response buffer as additional info if it fails
1317 to decode the SRU response.
1319 Make wrbuf_json_puts available.
1321 --- 4.2.6 2011/07/28
1323 zoom: throw diagnostic for invalid value for option "sru". Before a
1324 bad SRU request was sent.
1326 Adding new utility wrbuf_vp_puts.
1328 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1330 --- 4.2.5 2011/07/21
1332 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1333 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1334 redirect was used at the same time.
1336 MARC line mode decoding: be less picky about length given - first
1337 5 digits of header that is.
1339 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1341 Changes to decoding of SRU records: a record with recordPacking=xml is
1342 modified with a new root element <yaz_record> if the recordData contains
1343 multiple children elements. This is to make the record XML parseable
1346 RPN to Solr conversion: encode special characters.
1348 Generic Frontend Server: fix uinitialized member, stepSize.
1350 --- 4.2.4 2011/06/21
1352 Fix a bug in SRU decoding of records.. The database records stored
1353 had un-initialized memory, but it would only be seen with yaz_record_render
1354 and type_spec="ext" .
1356 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1358 --- 4.2.3 2011/06/17
1360 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1362 --- 4.2.2 2011/06/10
1364 Add new utilities to convert from CQL to CCL . These utilities have
1365 prefix cql_to_ccl defined in cql.h.
1367 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1368 lead to memory heap corruptions when ICU utilities were in use.
1370 --- 4.2.1 2011/06/07
1372 Make compilation work without Libxml2.
1374 yaz-client: remove redundant blanks in display of searchResult-1 term
1377 --- 4.2.0 2011/05/18
1379 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1380 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1382 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1383 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1384 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1385 Note that the CQL sortby spec is only converted when the GFS is already
1386 converting from CQL to RPN (cql2rpn element).
1388 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1389 specify whether to collapse delimitors or not. The existing nmem_strsplit
1390 do collapse (collapse parameter = 1).
1392 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1394 Rename internal func yaz_use_attribute_create. While non-static, this
1395 function is not declared in a public header.
1397 --- 4.1.7 2011/03/15
1399 Add -lCrun when linking with ICU on Solaris.
1401 More quicks character set conversions for OPAC records.
1403 --- 4.1.6 2011/03/10
1405 fix problem with record_render: records were converted (character set
1406 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1408 --- 4.1.5 2011/03/08
1410 SRU: add methods for handling DADS SRU-proxy facets.
1412 Separate OPAC record character set for ZOOM_record. yaz_record_render
1413 allows a character set given as charset=from/opacfrom,to where 'from' is
1414 the character set of a bibliographic record, 'opacfrom' is character set
1415 of OPAC record and 'to' is the target character set.
1417 --- 4.1.4 2011/02/21
1419 yaz-client: show may XML format records. Command show followed by 'format'
1420 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1423 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1426 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1428 --- 4.1.3 2011/01/27
1429 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1431 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1432 this package can be distinguished from other vendors.
1434 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1435 as determined by configure
1437 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1439 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1440 returns no error and no record, the present request is considered
1441 partial (only a subset of the records could be returned by backend), and
1442 so it is appropriate to set Present Status to partial-4.
1444 --- 4.1.2 2010/11/02
1446 Move yaz-config man pages to section 1.
1448 More documentation about Solr.
1450 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1451 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1452 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1453 peers on some Linux systems. However, in general that does not work
1454 so YAZ can not rely on that to work. Debian changed behavior in this
1455 respect from Debian lenny to Debian squeeze (still testing as of Oct
1457 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1459 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1461 --- 4.1.1 2010/10/05
1463 Fix yaz-config output: echo_source not set correctly by configure.
1465 --- 4.1.0 2010/10/05
1467 Solr Web Service support for yaz-client and ZOOM.
1469 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1471 --- 4.0.12 2010/08/17
1473 Z39.50 facet support. Facet specifications are passed for search in
1474 other-information with ASN.1 as defined in facet.asn and OID
1475 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1476 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1477 3 is limit (number of entries to get in response). yaz-ztest returns
1478 dummy facets if a client asks for them.
1480 --- 4.0.11 2010/07/09
1482 CCL fixes: bug 2895 and bug 3539.
1484 GR1-display: add comma in display - was removed by mistake in
1487 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1489 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1491 --- 4.0.10 2010/06/18
1493 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1494 result set from a connection. The result set will be on its own
1495 thereafter; no operations on it will perform retrievals from a target.
1496 Only cached copies are returned.
1498 ZOOM C:fix case for HTTP servers responding with Connection:close.
1499 Ensure that if there is a current task it is resumed (like fetching
1500 more records in a result set) . Bug #3484.
1502 PQF parser: use odr_atoi for Odr_int (not atoi)
1504 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1505 values that contain any non-digits are treated as string attributes
1506 (previously decoding only checked for leading character ([0-9]). PQF
1507 encoding: attribute string values are not surrounded by double-quotes.
1509 --- 4.0.9 2010/05/21
1511 New utility for managing threads - thread_create.h.
1513 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1514 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1515 but YAZ' implementation do.
1517 Fixes for yaz_cond-functions on Windows 7.
1519 DLL export more symbols.
1521 zoomsh: show record do NOT render opac.
1523 Remove *.la files from Debian and RPM packages.
1525 --- 4.0.8 2010/05/11
1527 Debian package libyaz-dev depends on libgnutls-dev again (was
1528 removed in YAZ 4.0.6, but due to Libtool it is still needed
1529 even though yaz-config do not list libgnutls libs).
1531 ZOOM: Use only one WRBUF for returning string results for
1532 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1534 ZOOM: ZOOM_connection do not use a shared pointer to
1535 ZOOM_resultset after ZOOM_resultset is destructed by
1536 user. Reverts to YAZ 4.0.4 behavior.
1538 --- 4.0.7 2010/05/04
1540 record-conv: fix problem with at least one XSL conversion -
1541 due to probably incorrect usage of XML XSL documents.
1543 --- 4.0.6 2010/04/29
1545 Fix yaz-config for static mode and the use of SSL (gnutls).
1547 --- 4.0.5 2010/04/29
1549 Forward decl timeval struct in mutex.h and gettimeofday.h.
1551 yaz-config: fix 'static' mode linking.
1553 --- 4.0.4 2010/04/28
1555 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1556 are wrappers for pthreads or Windows. For Windows these are put in
1557 a separate DLL: yaz_cond4.
1559 libyaz.la (whole source) is compiled with thread. If thread support
1560 is enabled enabled, all source of YAZ is compiled with treading support.
1561 This allows core utilities such as yaz_log to use thread facilities.
1562 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1563 thread utilities. This commit moves mutex utilities (mutex.c) from
1564 libyaz_server.la to libyaz.la.
1566 yaz-json-parse displays leading text until error.
1568 --- 4.0.3 2010/04/09
1570 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1571 patch from Giannis Kosmas.
1573 SRU: no longer URL encode SRU database. The URL for an SRU server is
1574 a URL and such is alreeady encoded - at least when given with leading
1575 http:// or https://. This reverts behavior to YAZ 3.0.50.
1577 Support for new MARC XML notation TurboMARC which like MARCXML is a
1578 complete representation of MARC/ISO2709.. This one, however, is more
1579 compact and allows for faster processing with XSLT. TurboMARC can be
1580 used in the marcdisp.h API, from the yaz-marcdump utility and from
1583 yaz-ztest can be configured - via the database - to perform certain
1584 delays when it performs operations search, present and single record
1585 fetch. This allows testers to make yaz-ztest act as a real or even slow
1586 Z39.50 server. Refer to the yaz-ztest man pages for details.
1588 --- 4.0.2 2010/03/09
1590 wrbuf_destroy allows NULL WRBUF passed to it.
1592 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1594 Add ZOOM_connection_close.
1596 No fixed size buffers for ZOOM shell - bug #3257.
1598 tstodr: make it work on s390 platform.
1600 New icu iterator-functions. The new icu_iter-functions makes it possible
1601 to use ICU chains from many threads.
1603 yaz-client: better syntax check for show command.
1605 --- 4.0.1 2010/01/26
1607 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1610 New simple local-file XML include facility which allows file glob-patterns.
1611 Refer to yaz/xml_include.h.
1613 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1616 ZOOM_record_get supports new parameter "format" which makes it format XML
1619 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1620 JSONText in ECMA-262) is JSONValue, not JSONObject.
1622 --- 4.0.0 2010/01/20
1624 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1625 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1627 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1628 POSIX/Unix builds .so with major version 4.
1630 Remove old LOG_-defines from log.h. They have been obsolete and
1631 undefined by default for the last 5 years.
1633 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1635 GFS: Remove socket (int *fd) from search_rr handler. The socket
1636 descriptor ptr is a facility that allowed a search handler to supply
1637 a socket which would serve as a callback - when search was complete.
1638 This facility has now been in use for years.
1640 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1641 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1642 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1643 returns 'const char *' rather than 'char *. The returned string is
1644 read-only and should not be modified by applications. COMSTACK cs_close is
1645 now a void function - it no longer returns int. No applications check for
1646 the value and the implementations has always returned 0.
1648 ZOOM: use size_t for scan hit counts and str size. Functions
1649 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1650 occ (hit count) and len (string length) are now of type size_t pointer
1651 rather than int pointer. This is to be able to represent large hit counts
1652 and to also just to use the proper type for string length (strlen result).
1654 New JSON parser. Refer to include/yaz/json.h .
1656 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1657 Used to be int in some cases. Many wrbuf_-functions used to return an int
1658 indicating some length.. These return values were never used. And so they
1661 ODR: odr_malloc, odr_total now takes size_t for size.
1663 clone_z_type: fix leak; occurred for encoding failures.
1665 --- 3.0.52 2009/12/03
1667 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1668 bug was introduced in 3.0.51.
1670 --- 3.0.51 2009/12/02
1672 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1674 tcpip comstack: fix leak for getaddrinfo.
1676 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1677 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1678 Decoding of SRU "path" database is performed by private function
1679 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1680 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1682 yaz-client: honor base command for SRU. Change when database setting
1683 is applied for SRU and ensure it is kept when a connection is reset.
1684 Change also the way errors are displayed or SRU (decoding of packages).
1686 --- 3.0.50 2009/11/02
1688 Add support for extra request / response data for SRU codecs and GFS.
1689 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1690 for extra data response buffer and length. For the GFS, both request
1691 and response data (XML) is carried in extra_args and extra_response_data
1692 for the search handler. Patch by Ko van der Sloot.
1694 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1695 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1696 10010). This fixes bug #2113.
1698 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1699 cmdfile included a 'quit' command that would result in a memory violation.
1701 --- 3.0.49 2009/10/01
1703 Make a number of functions defined in xmlquery.c static. These have
1704 never been declared in a public header file (yaz/xmlquery.h) and was
1705 made public by mistake.
1707 Improve speed of character conversions (iconv utilities). This makes
1708 conversions from MARC-8 faster.
1710 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1711 unless type desired is "raw". This will prevent type "xml" from
1712 returning ISO2709 .. Which obviously can not be XML parsed.
1714 Fix memory leak in ZOOM that would occur if option apdulog was used
1715 on a re-used connection.
1717 Frontend server logs HTTP requests.
1719 Frontend server now sends Z39.50 close when it times out (sesssion has
1720 been idle for too long). Versions 2.0.30 and earlier also sent close.
1721 But due to a mistake this was disabled in all versions after that, i.e.
1722 the server would just close the socket immediately.
1724 yaz-client emits a better message when receiving an unrecognised
1725 userInformationField.
1727 Skip zero-length subfields when decoding ISO2709. This rare case happens
1728 if a record has two FS characters in a sequence. Without this patch
1729 there would be a reference beyond char array in using_code_len fragments
1732 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1734 --- 3.0.48 2009/08/28
1736 The show command offered by the zoomsh command now takes a 3d optional
1737 parameter type which is what is passed to ZOOM_record. If the type
1738 argument is omitted, "render" is used.
1740 RPN to CQL conv may use USE string attributes (bug #2978).
1742 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1744 --- 3.0.47 2009/07/08
1746 Function yaz_xml2query allows a diagnostic element in the PQF XML
1747 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1748 code and additional info respectively.
1750 The BER BOOLEAN is now the integral type Odr_bool which still happens
1751 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1752 typedef'd to Odr_int. This is still an integral 'int', but it may be
1753 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1754 ASN-1 compiler as well as programs has been updated to use the new types.
1756 --- 3.0.46 2009/06/08
1758 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1759 only the bibliographic record was rendered. For type=opac, an OPAC
1760 record is only returned if it is present.
1762 iconv: small fix for encoding of advancegreek.
1764 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1766 yaz-client: option auto_reconnect=on really reconnects.
1768 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1770 server: avoid null ptr ref for for yaz_poll errors.
1772 build: fix RPM build for RHEL 5.3.
1774 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1776 --- 3.0.45 2009/03/31
1778 Fixed bug #2709: TCP connect returns Invalid argument.
1780 Fixed compilation for mingw.
1782 Honor charset for raw records (ZOOM_record_get).
1784 Fixed use of errno for threaded mode that was seen on Solaris 10.
1786 Fixed argument passing with blanks in value for Windows Service.
1788 Disable YAZ' own log rotate by default (no 1 GB limit).
1789 The variable l_max_size which specifies the log file limit is set to 0
1790 (DISABLED): This is due to the fact that YAZ is most often deployed using
1791 logrotate. Also YAZ can not perform log rotate because of unsufficient
1792 permissions (setuid).
1794 --- 3.0.44 2009/02/17
1796 List supported encodings in man page for yaz-iconv.
1798 Fixed missing SSL libs for --libs output
1800 Re-established OID record syntax application-xml. Nobody should use it
1801 but we don't want to change soname because of this symbol being absent.
1803 --- 3.0.42 2009/02/02
1805 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1807 Added member named_result_sets for init handler struct for the GFS. This
1808 allows a server to disable named result sets.
1810 Removed OID record syntax application-xml.
1812 Added support for rule-based transliterator for ICU wrapper of YAZ.
1814 Fixed bug #1902: yaz-icu XML output.
1816 Make YAZ checks Emacs friendly.
1818 BITSTRING value shows value. Bug #2346.
1820 ISO2709 decoding: skip control characters from indicator data.
1822 Omit sort key by default in yaz-icu's output.
1824 Allow combined single char options (again) for YAZ' options function.
1826 Utility yaz-marcdump got option to display YAZ version (-V).
1828 Allow YAZ to use ICU 3.4.
1830 Added new ICU test case which illustrates removal of diacritics.
1832 --- 3.0.41 2008/12/29
1834 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1836 --- 3.0.40 2008/12/29
1838 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1841 Fixed bug #2352: yaz-marcdump crashes for certain record.
1843 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1845 Added support for Danmarc2 to UTF-8 conversion.
1847 Added support for ISO5426 to UTF-8 conversion.
1849 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1850 implementation version.
1852 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1854 --- 3.0.38 2008/11/10
1856 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1857 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1859 ZOOM C now interprets databaseName option for ZOOM connection as path
1862 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1864 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1866 Dummy Libxml2 types no longer defined in headers of YAZ'.
1868 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1871 --- 3.0.36 2008/09/26
1873 Various ODR chapter fixes.
1875 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1877 Added missing source for Windows compilation, mutex.c.
1879 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1881 For SRU connections in ZOOM all records up to "count" are now fetched.
1883 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1884 in Windows due to bad error handling for Libxml2.
1886 Added facility for sending arbitrary records (ASN.1 any) using
1887 ZOOM C's Extended service update. Patch by Sam Reynolds.
1889 New options for ZOOM C's connection, logapdu which makes ZOOM log
1892 --- 3.0.34 2008/06/18
1894 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1896 --- 3.0.32 2008/06/12
1898 Fixed memory violation that could occur when decoding UTF-8. This bug
1899 was only present in 3.0.30 of YAZ.
1901 --- 3.0.30 2008/06/06
1903 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1904 GNU TLS is used by default (if found).
1906 yaz-ztest returns OPAC records if a client asks for OPAC.
1908 Improved speed of MARC-8 encoding.
1910 Added support for lossy and loss-less MARC-8 encoding.
1912 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1914 Added new Windows Service wrapper (sc).
1916 yaz-client's itemorder command may now send a file.
1918 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1920 Added new function yaz_log_xml_errors.
1922 Allow (but warn) unknown XML attributes in MARCXML parsing.
1924 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1926 The UTF-8 to MARC-8 conversion now uses a different set of characters
1927 for Greek symbols. Bug #2120.
1929 --- 3.0.26 2008/02/21
1931 Added yaz_daemon (daemon.h).
1933 Fixed bug #2068: pkg-config trouble
1935 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1937 --- 3.0.24 2008/01/28
1939 Document --with-xml2 option.
1941 Added OPAC XML XSD (etc/opacxml.xsd).
1943 Allow glob mask for name attribute in retrieval element for the
1944 generic frontend server's retrieval facility.
1946 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1947 except POLLIN/POLLOUT.
1949 Fixed error handling in cs_listen. Bug #2037.
1951 --- 3.0.22 2008/01/20
1953 Fixed version in yaz/yaz-version.h.
1955 Fixed bug #2027: Crash when closing connection.
1957 Changed configure so that ICU support is only enabled if only ICU
1958 and Libxml2 is available (because the ICU chain is XML based).
1960 --- 3.0.20 2008/01/15
1962 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1963 is built. Only this DLL depends on the ICU runtime.
1965 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1966 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1968 Changed license of CCL module to 'Revised BSD'. After consultation with
1969 remaining members of the original EUROPAGATE consortium, we are re-issuing
1970 the CCL module without a separate license. The software was developed by
1971 Index Data as part of a research project. The special license was included
1972 to help feed usage information back to the project consortium to support
1973 project evaluation. At this time, the project consortium has long-since
1974 disbanded, and the majority of the original principals have retired. At the
1975 same time, we have significantly modified the software during the following
1976 years, to the point where very practically no original code remains. To
1977 simplify re-use of the software, we have contacted those members of the
1978 consortium who could be reached, and agreed to re-issue the module as a
1979 proper part of the YAZ package.
1981 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1983 CQL closer to being version 1.2 compliant. CQL also allows free-form
1984 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1987 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1988 bug could make Extended services handling crash in the ZOOM layer. This
1989 bug was only present in YAZ 3.0.18.
1991 --- 3.0.18 2007/12/19
1993 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1996 yaz-marcdump reads and writes collection wrapped records.
1998 Handle OPAC for record conversion module.
2000 Fixes for ICU wrapper.
2002 Allow ICU libs to be controlled with --with-icu .
2004 --- 3.0.16 2007/11/12
2006 Added yaz_poll which is a wrapper for select/poll. When poll is available
2007 and non-buggy, it is used, by yaz_poll . This allows more than 1024
2008 sockets to be in use.
2010 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
2011 functionality through an XML based configuration (ICU chain). This system
2012 is useful for search facilities such as Pazpar2 and Zebra that needs to
2013 perform tokenization of indexed material. The ICU code in a separate
2014 library libyaz3_icu.a.
2016 Added HTTP tunnel facility for COMSTACK, bug #1752.
2017 This is a facility that allows a Web proxy, such as squid, to tunnel
2018 Z39.50 traffic. This facility is "transparent" to must applications
2019 using YAZ. It's enabled by using pseudo transport connect: followed by
2020 the proxy address, followed by command, then follwed by he regular
2021 "virtual" addresss. For example,
2022 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
2024 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
2026 --- 3.0.14 2007/09/21
2028 Fixed bad memory reference in ZOOM_record - cuased by member not being
2029 initialized. This was a problem only in YAZ 3.0.12.
2031 Fixed bug in conversion from MARC to XML: Non-XML characters in control
2032 fields were not removed.
2034 Changed the way C code is generated from codetables.xml. Made a MARC-8
2035 conversion trie for each characterSet section rather than codeTable.
2036 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2037 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2039 --- 3.0.12 2007/09/12
2041 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2042 from ZOOM_record_error).
2044 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2046 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2048 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2050 Better SRW-to-Bib-1 diagnostic mapping.
2052 ZOOM C and yaz-client announces SRU version 1.2 by default.
2054 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2057 Fixed in yaz_sru_decode to allow other version than 1.1.
2059 --- 3.0.10 2007/08/22
2061 Added support for SRU scan for ZOOM.
2063 Added support for the use of the older versions or Extended Service
2064 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2065 set to the version , 1=first, 2=second, 3=third. The third version is
2066 what ZOOM C has used so far. And that, obviously, is the default.
2068 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2069 therefore in Zebra and in SimpleServer-based applications). The new
2070 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2071 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2072 which is passed into the back-end search callback function.
2074 Added support for HTTP Basic authentication in clients: the SRU/W
2075 codec encodes the username/password elements of the PDU structure
2076 appropriately, and these may be set using the "user" and "password"
2077 options in ZOOM-C applications (the same options that are used for
2078 Z39.50 authentication).
2080 --- 3.0.8 2007/06/25
2082 Fixed bug #1208: SSL appears to be broken in ZOOM.
2084 Fixed bug #1206: Libxml2 include path weirdness.
2086 Added oid_name_to_dotstring.
2088 Allow elementSetName to be specified for ZOOM C record update.
2090 Allow waitAction to be specified for ZOOM C based for Extended Services.
2092 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2093 syntax OID. Bug introduced in YAZ 3 series.
2095 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2097 --- 3.0.6 2007/06/06
2099 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2100 directory. yaz-client now reads commands from file given by option -f
2101 if specified; then tries to read .yazclientrc in current directory.
2102 Failing that, it reads .yazclientrc from user's home directory.
2104 Added support for correlationInfo Note and ID for Record Update via
2107 Added yaz-client command querycharset which specifies character set for
2108 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2109 (termListAndStartPoint).
2111 Charset ISO5428:1984 is an alias for ISO5428-1984.
2113 Implemented a way to perform scan in a result set using Z39.50. This
2114 is achieved by attaching the result set name in the characterInfo
2115 (type InternationalString) of OtherInformation in the Scan Request PDU.
2116 The result set is identified in the otherinformation by the new OID:
2117 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2118 This allows for scan in result set and faceted search . Zebra did some
2119 of this in the APT term using attribute type 8 and value being result
2120 set. Using the OtherInformation approach for this is cleaner and easier
2121 to work with in proxies and the like. This facility can be used in
2122 yaz-client using new command setscan which takes a result set as first
2123 argument, start position (APT) as second.
2125 Changed decoding of SRU XML packed records to deal with servers that
2126 have recordData with XML data with multiple root nodes. Also make
2127 comparison for recordPacking case insensitive. Again, one server
2128 returns "XML" where others return "xml".
2130 For SRU responses allow Content-Type application/xml as well as text/xml.
2132 --- 3.0.4 2007/05/21
2134 Fixed bug in character set conversion of BER strings. Bug introduced
2137 --- 3.0.2 2007/05/08
2139 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2141 For OID class, use oid_class consistently.
2143 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2146 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2147 character set for bibliographic information interchange". By Giannis Kosmas.
2149 Added documentation on new OID API.
2151 --- 3.0.0 2007/05/02
2153 Changes to generic frontend server interface: added new member
2154 'query_charset' for bend_initrequest structure. A backend init handler
2155 should set this member to its native character set for query terms.
2156 When defined, the frontend server logic will announce this character set
2157 to a client if the negotiationModel bit is set by the client. All server
2158 implementors are encouraged to specify this. If a backend server does not
2159 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2161 Added CCL utility to remove terms (stop words) from resulting RPN
2162 tree. This is handled by functions with prefix ccl_stop_words_ .
2164 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2165 terms in RPN queries.
2167 Clean-up the CCL API. Moved some internal structures from ccl.h to
2168 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2169 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2170 This is replaced by ccl_parser_find_str which takes a string instead.
2172 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2173 libyaz.la is the core of YAZ except the generic frontend server and
2174 does not depend on POSIX threads anymore. libyaz_server.la is the
2175 generic frontend server facilities and uses POSIX thread functionality
2176 if available. The libyaz.la no longer depends on POSIX threads because
2177 the number of global structures is limited. NMEM no longer re-uses blocks
2178 between threads ; it simply free's memory immediately but allocates in
2179 "large" chunks as usual. We don't expect any performance penalties
2180 because of this. The yaz_log system is still using a global log_level so
2181 caution must be taken when modifying it with yaz_log_init_.. +
2182 yaz_log_mask_str. This, however, should not cause any trouble because
2183 these functions are called during initialization of application code
2184 anyway. `yaz-config --libs server` returns libs for server applications;
2185 `yaz-config --libs` returns libs for non-server applications.
2187 New OID database - with public definitions in oid_db.h. Removed old OID
2188 database including the head oid.h and definitions such as enum oid_value
2189 and struct oident. The new OID database uses the same string names as
2190 before but the 'protocol' is gone. There are now only two representations
2191 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2192 converts from string to OID; functions with prefix yaz_oid_to_string
2193 converts the other way.
2195 Change to emit_term() in CQL-to-PQF query translation: when a term has
2196 the /regexp relation modifier, do not process it for leading and
2197 trailing "^" and "*", which have quite different meanings in regular
2200 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2201 write handlers no longer carries a 'last' parameter. This will make
2202 yaz_iconv flush "less" characters. A flush is performed by call to
2203 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2205 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2206 removed, because function yaz_query_to_wrbuf does the same.
2208 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2209 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2211 Deprecated MARC utility functions removed.
2213 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2216 Branch split: YAZ_2_1_55_branch
2218 --- 2.1.54 2007/03/16
2220 Fix to ZOOM-C so that transparent reconnection is properly handled on
2221 connections that are in asynchronous mode.
2223 Fixed compilation on OpenBSD 4.0.
2225 Large strings in GRS-1 records are now properly displayed in yaz-client.
2227 Added character conversion support for "advancegreek"; based on patch from
2230 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2231 sequence is met. Before the error was not set so it would be unknown.
2233 Adjust yaz-marcdump MARC reader so that it skips until record separator
2236 --- 2.1.52 2007/03/07
2238 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2239 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2240 fd_set structure used as a bitmask for the FDs to be selected on.
2242 Using ACX_PTHREAD macro to check for POSIX threads.
2244 Fixed have-vsnprintf check.
2246 --- 2.1.50 2007/02/23
2248 Fixes for configure on BSD. Bug #900.
2250 Added snprintf/vsnprintf wrappers for systems that don't have
2251 limits (heavens forbid).
2253 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2254 created before all previous tasks were completed and removed from the
2255 task queue, the new task could be removed by a mistake.
2257 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2259 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2261 Fixed bug #832: Problem with MARC/charset in yaz-client.
2263 Fixed bug #668: save command line history for yaz-client.
2265 Fixed bug #830: pkg-config support.
2267 --- 2.1.48 2007/01/23
2269 Extended ZOOM result set options with two options that may be read by
2270 a client: resultSetStatus and presentStatus with values as specified for
2272 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2274 Fixed bug #827: Using SSL fails on Debian etch.
2276 Fixed bug #826: Weird looking chars for set of MARC records.
2278 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2279 that is treated as an ItemOrder with itemRequest being an XML document
2280 external. The value of "doc" is the content.
2282 Extended the GFS search facility. New member of bend_search_rr
2283 'estimated_hit_count' signals that hits is known to be an estmate
2284 (higher or lower than real hit count). New member 'partial_resultset'
2285 signals that the search was partial (hit count is lower or equal than
2286 real hit count). For Z39.50, the information is stored in resultSetStatus
2287 member of SearchResponse APDU. For SRU, the information is signalled
2288 via SRU diagnostic 59: "Result set created with valid partial results
2291 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2293 --- 2.1.46 2007/01/13
2295 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2297 Added ZOOM_connection_peek_event.
2299 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2300 the following new functions:
2301 ZOOM_event_nonblock, ZOOM_connection_process,
2302 ZOOM_connection_get_{socket,mask,timeout},
2303 ZOOM_connection_fire_event_{timeout,socket}.
2304 The existing blocking event handler, ZOOM_event, is a wrapper for the
2305 + blocking ZOOM_event_sys_{poll,select}.
2307 Implemented function ccl_xml_config which parses XML version of CCL
2308 configuration (bug #798).
2310 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2312 Added timings utility (yaz/timing.h)
2314 --- 2.1.44 2007/01/03
2316 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2319 Fixed bug #779: Rotation of apdu.log fails.
2321 Fixed for character set conversions:
2322 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2323 Honor G1 set in MARC-8 decoding.
2325 --- 2.1.42 2006/12/17
2327 Fixed bug #775: char conversion does not handle Alternative UTF-8
2330 Implemented function yaz_marc_read_line which parses MARC line format
2331 records. There is a wealth of formats out there. So far, this function
2332 reads line records produced by yaz_marc_write_line.
2334 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2335 more generic and easier to remember(!) options: -i format and -o format
2336 which specifies input format and output format respectively - where
2337 format is one of "marc", "marcxml", "line", "marcxchange".
2339 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2340 does not print anything except warnings for records.
2342 For yaz-marcdump, added support for MARC split into files (-s) with a given
2345 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2346 spec, at http://www.loc.gov/standards/sru/record-update/
2347 This has changed the binary layout of the following structs:
2348 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2349 bend_update_rr . Patch by Ko van der Sloot.
2351 Added GFS utility function bend_assoc_is_alive which returns 1 if
2352 association is still alive (client is connected); 0 otherwise (client
2353 closed connection). This allows busy servers to stop working for
2356 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2357 been a separate piece of software. This version of ziffy has been modified
2358 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2360 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2362 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2363 Client code may now interrogate options such as "init_opt_sort" to
2364 find out whether the server claims to support various options.
2366 --- 2.1.40 2006/11/27
2368 Added utilities yaz_{set,get}_esn to set/get element set name from
2371 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2372 of YAZ and has been so since YAZ 2.1.10.
2374 Implemented ZOOM_record_error which returns error information for
2375 record (surrogate diagnostic).
2377 --- 2.1.38 2006/10/31
2379 Updates for SRU Update by Ko van der Sloot:
2380 1. Changed name from "operation" to "action"
2381 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2382 versions in the code, marked as 'backward compatible'.
2383 3. Added diagnostics for SRU Update.
2385 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2387 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2389 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2391 For GFS, fixed problem with SRU diagnostic 'First record position out of
2392 range' being issued for 0 hits.
2394 zoomtst10 part of Windows Build.
2396 --- 2.1.36 2006/10/13
2398 Implemented yaz_filepath_comp which splits a path into file path
2399 components (required by Zebra 2.0.3+).
2401 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2402 BSD inspired license until now so this should not have any real impact on
2403 anybody. See http://www.opensource.org/licenses/bsd-license.php
2405 Fixed bug #687: Missing log lines.
2407 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2410 Fixed bug #689: SRU diagnostics to be added.
2412 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2413 whether a connection is idle (no more work do do).
2415 --- 2.1.34 2006/10/04
2417 Change type of optval from long to int for invocation of setsockopt with
2418 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2420 Added support for specifying the max log file size for the Generic
2421 Frontend Server. The size is given with option -r.
2423 --- 2.1.32 2006/09/21
2425 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2427 --- 2.1.30 2006/09/17
2429 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2432 Fixed bug in Generic Frontend Server that could cause a server to stop
2433 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2435 For the generic frontend server, the maximum record size is used as maximum
2436 size of incoming packages (SRU + Z39.50). The value until was previously
2437 only used in Z39.50 Init negotiation and, later, in a session controlled
2438 sizes of records returned. This is controlled using -k option. It can be
2439 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2441 --- 2.1.28 2006/09/04
2443 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2446 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2448 New option for yaz-marcdump -lpos=value which allows setting a portion
2449 of MARC header to a certain value.
2451 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2453 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2454 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2456 --- 2.1.26 2006/08/15
2458 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2461 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2463 --- 2.1.24 2006/08/08
2465 Fixed MARC ISO2709 encoding routines to deal with character set
2468 Minor changes to GFS logging. Database included in search request log
2471 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2472 cached/multiple records.
2474 Shared libraries are built by default on Unix+configure.
2476 Changed cql2pqf transformation to use a different evaluation order. The
2477 new order is: always, relation, structure, position, truncation, index
2478 and relationModifier. Old order was: always, relation, relationModifier,
2479 structure, index, position, truncation. Note that the the latter ones
2480 override former ones for identical attributes.. The new scheme means that
2481 it is possible to override any existing attribute with a relationModifier.
2482 And also that it is possible to override everything for the index rule
2483 (except the ones listed in relationModifier). No order is perfect but this
2484 one, we believe, covers more real cases.. The "always" should have been
2485 called "default", since the attributes there can be overridden with all
2488 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2489 compilation phase, but also for yaz-config --cflags output. This allows
2490 us to have public headers with Libxml2 stuff in them . It should also,
2491 eventually, make Libxml2 checks redundant in packages using YAZ, such
2494 --- 2.1.22 2006/06/15
2496 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2497 stored in uri, message and details.. Previously diagnostics were stored
2498 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2499 compatibility.. but he's probably the only one affected, so.
2501 Added support for CCL, compiled on the client side, in ZOOM-C. This
2502 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2503 input; the resulting query objects can be used for for searching with
2504 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2506 YAZ' configure searches for OpenSSL by default.
2508 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2509 SL_CTX_use_certificate_file. See
2510 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2511 for more info. Thanks to Ko van der Sloot.
2513 --- 2.1.20 2006/06/02
2515 Bug #600: SRU GET, POST support for yaz-client. Introduced
2516 command 'sru' which selects method SOAP/GET/POST.
2518 Allow missingValueAction to be specified for the sortspec string -
2519 function yaz_sort_spec. By default, the missing value action is null.
2520 Use ! to specify "abort". Use = followed by stringvalue to specify default
2523 Ensured that Present-handler (if defined) is called in GFS before any call to
2524 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2525 searchRetrieve requests.
2527 Documentation for YAZ is now based on the Docbook XML/XSLT using
2528 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2529 is no longer depending on jade/openjade or docbook-to-man scripts.
2530 PDF is no longer part of the distribution - but can optionally be
2531 made using DSSSL/jadetex or FOP.
2533 Added retrieval handling support in Generic Frontend Server to support
2534 conversion between MARC/XML as well as XSLTtransforms. See
2535 etc/yazgfs.xml for an example.
2537 Added Authentication support to Generic Frontend Server in SRU
2538 mode. Authentication using HTTP Basic is supported, as is the use
2539 of 'x-username' and 'x-password' parameters in the request itself.
2541 Added support for a new character set MARC8s identical to MARC8 except
2542 that it converts combined characters to single Unicode characters in the
2543 Latin-1 range (when possible).
2545 --- 2.1.18 2006/04/24
2547 ASN.1 compiler 0.4: generates brief Doxygen file header for
2548 generated .h/.c files.
2550 Utility yaz_iconv now supports conversion to MARC-8.
2552 New facilities for the MARC module. The reading - and writing of
2553 content are separate methods for the yaz_marc_t handle. The following
2554 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2555 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2556 format). Write functions have prefix yaz_marc_write_.. The existing
2557 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2558 available. Removed support for OAI-MARC and simplexml (not the
2559 simplexml from PHP5).
2561 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2562 to be returned for this connection.
2564 --- 2.1.16 2006/03/31
2566 Allow multiple languages and charsets to be specified with
2567 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2568 negcharset iso-8859-1,utf-8
2570 Translation of proximity nodes from CQL into PQF now works.
2572 Moved to automake 1.8, 1.9.
2574 Added function yaz_log_set_handler which allows a log handler to be
2575 installed. This handler will be called for all log messages. Output
2576 to file is also produced; but that can be disabled by passing NULL
2577 fname to yaz_log_init_file.
2579 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2581 For SRW (including GFS), accept application/soap+xml as content-type
2584 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2585 produces NO stylesheet reference even if a default stylesheet is specified
2588 --- 2.1.14 2006/03/14
2590 Updated Windows package to include yazd.dll + yazd.lib for the
2591 Development component.
2593 If the environment variable YAZ_LOG is set, then it is used as a
2594 string indicating the default level of logging to use if not
2595 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2596 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2597 used as before. So, for example, to omit warnings from YAZ logging,
2598 export YAZ_LOG=-warn
2600 cql_transform() now map structure and other attributes before indexes,
2601 so that index-specific structures and other attributes can override
2602 defaults. So now a combination of mapping specifications such as:
2604 index.dc.date = 1=date-modified 4=5
2605 does the right thing.
2607 cql_transform() now also respects the "always" mapping specification,
2608 which establishes an initial set of attributes to be used for all
2609 terms except where overridden by more specific attributes associated
2610 with the index, relation or modifier.
2612 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2613 which mode to use; one of "post", "get" or "soap" (SRW, default).
2615 Fixes for yaz_iconv routines: changed trie-based character set conversions
2616 to use only non-negative values for bit fields due to Sun's C compiler not
2617 supporting negative values.
2619 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2620 sequences where not read correctly. Fix by Rustam Usmanov.
2622 Updated win/makefile to use options, settings which makes things
2623 compile with VS C 2005.
2625 --- 2.1.12 2006/02/01
2627 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2629 In ZOOM socket code, use select instead of poll on MacOSX.
2631 ZOOM-C now support client-side compilation of CQL into RPN that is
2632 sent to the server, enabling CQL to be used against all Z39.50
2633 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2634 ZOOM_query object, and submit it using ZOOM_connection_search().
2635 The CQL-to-RPN translation uses a configuration file, the name of
2636 which must be specified in the Connection's "cqlfile" option.
2638 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2639 function, which takes as its start-term parameter a ZOOM_query object
2640 (which may have had either CQL or RPN set into it).
2643 --- 2.1.10 2005/11/29
2645 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2646 GFS to support this as well. Backend handler, bend_srw_update, does the
2647 update work. Code contributed by Ko van der Sloot.
2649 Allow retrieval of Search Result-1 information in ZOOM by the use of
2650 options that are attached to a result set. ZOOM documentation updated
2653 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2654 UTF-8 conversion. Patch by Raj Patel.
2656 Added option -m to GFS to control formatting of timestamps in log file.
2658 Added 'exit' as synonym for 'quit' in yaz-client
2660 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2661 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2662 for the new members. Patch by Ko van der Sloot.
2664 Added support for SRU POST. It is supported for content-type
2665 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2667 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2668 Instead make the library libyaz.la multi-threaded. Threading as a whole
2669 can still be disabled by configure option --disable-threads. Previosly,
2670 with older GLIBCs there were problems with MT libs under Apache. This
2671 has now been fixed a long time ago.
2673 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2676 CQL module modified to be case insensitive for relations/indexes/operations.
2678 Fixed bug in CQL transform code: incorrect value relationModifieder
2681 Added 'show all' command for yaz-client which retrieves all results
2684 Added new yaz-client, xmles, which takes a (private) OID and
2685 a document to be sent as an extended service request.
2687 Describe new yaz-client commands wait_response and set_auto_wait.
2689 Increase TCP/IP listener backlog from 3 (which I am guessing was
2690 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2691 that the socket will queue as many incoming connections as it's able
2692 to handle ongoing connections. In other words, it will never now
2693 refuse a connection that it would be able to handle merely because
2694 it's not got around to accepting() enough of the pending connections
2695 yet. This is the behaviour anyway under Linux, where the listen()
2696 argument is ignored; but not under BSD and on systems such as
2697 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2698 YAZ-based servers should now be uniform across operating systems in
2701 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2702 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2703 This allows yaz-marcdump to read large MARC batches (>2 GB).
2705 Modified all YAZ source files - except the source which is auto-generated
2706 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2709 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2710 corresponding to the existing *_setl() function. These allow option
2711 values containing arbitrary valuues.
2713 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2714 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2715 except that it returns an indicator of whether or not the sort
2716 criterion was accepted (0 for OK, -1 for invalid).
2718 --- 2.1.8 2005/06/07
2720 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2721 MARC output rather than returning "new" buffer.
2723 yaz-client warns about unknown init options.
2725 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2727 --- 2.1.6 2005/05/24
2729 Added support for SRW sort in Generic Frontend Server. Patch
2730 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2731 sortKeys - or NULL if none is provided.
2733 Fixed bug #307: It was impossible to specify indefinite/no timeout
2734 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2737 Added support for multiple languages and charsets to be specified in
2738 ZOOM. Each charset/language is separated by a blank. If negotiation is
2739 in effect in init-response, Option
2740 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2741 Code based on patch by Vasiliy Osadchuk.
2743 Fixed bug #306: infinite recursion that occurred when calling
2744 yaz_log_level_init as the first call (before other log level or
2747 Fixed bug in scan handling in front end server: if preferred-Position-In-
2748 Response was non-present, a NULL pointer referece was performed.
2750 --- 2.1.4 2005/04/26
2752 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2753 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2754 now defined for all those error codes. So instead of putting 109 in
2755 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2756 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2758 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2761 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2763 Program yaz-client now exits and produces an error message if multiple
2764 Z39.50 servers are specified on the command line (none or one allowed
2767 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2770 --- 2.1.2 2005/03/16
2772 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2774 Fixed bug #272: Preserve spacing for CCL terms.
2776 --- 2.1.0 2005/03/14
2778 Added support for virtual hosts and multiple backend servers for
2779 the YAZ frontend server. The configution is XML based and
2780 support specificition of CQL to RPN mappings and explain information.
2781 See section "Virtual Hosts" in the YAZ manual.
2783 Extended OPAC display utility. OPAC display utility renders
2784 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2785 to supplement yaz_marc_decode_wrbuf.
2787 Fixed a bug in MARC decoder that could caused it to crash for some
2788 invalid MARC records. More diagnostics and warnings where added in
2789 XML output (warnings, etc are stored in comments).
2791 --- 2.0.34 2005/02/08
2793 Fixes for UNIX domain sockets. Bug #261.
2795 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2797 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2798 Added yaz_marc_subfield_str which defines subfield lead string which is
2799 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2800 yaz_marc_endline_str which defines end of fields string used in
2801 YAZ_MARC_LINE format. Default string is newline.
2803 Experimental support for MarcXChange. This format can be produced
2804 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2805 http://www.bs.dk/standards/MarcXchange.xsd
2807 Added yaz-client commands scansize that sets maximum number of
2808 entries to be returned by scan.
2810 --- 2.0.32 2005/01/11
2812 Added support for SRW scan in yaz-client and Generic Frontend Server.
2814 * Added whereInList member to SRW Scan Term.
2816 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2818 Fixed NMEM system to return aligned blocks on the smallest boundaries
2819 that are suitably aligned for all possible types on the particular
2820 architecture YAZ is being built for.
2822 --- 2.0.30 2005/01/04
2824 Fixed numerious warnings that was issued with newer versions of GCC.
2826 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2827 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2830 Make YAZ Generic Frontend Server slightly faster.
2832 Enhance (and reduce) logging for Generic Frontend Server.
2834 Revert YAZ log system so that it flushes every write operation
2835 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2837 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2838 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2839 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2840 will effectively disable old definitions.
2842 --- 2.0.28 2004/11/09
2844 Added yaz_log_time_format which specifies log format using
2847 Added yaz_log_module_level which returns mask for a module. Value
2848 is non-zero mask a if module is enabled; zero if disabled.
2850 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2851 in include/yaz/cql.h.
2853 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2855 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2857 Fixed bug #172: RPM builds does not enable SSL.
2859 Doxyfile.in part of dist. Doxyfile generated by configure.
2861 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2862 are given and the corresponding component does not exist.
2864 Extend CCL documentation in YAZ reference. Describe r=r.
2866 --- 2.0.26 2004/10/01
2868 Fixed MARC->MARCXML conversion to properly deal with
2869 fields, subfields, indicators having non-ASCII characters.
2871 Fixed MARC->MARCXML conversion so that ASCII control characters
2872 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2875 Added YAZ GFS support for conversion from Z39.50 surrogate
2876 diagnostics to SRW surrogate diagnostics.
2878 Bug fix: YAZ GFS did not return schema in explainResponse.
2880 --- 2.0.25 2004/09/30
2882 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2883 now converts recordSchema to elementSetName as well as schema URI.
2885 Fixed bug in COMSTACK that prevented HTTP request packages from being
2888 --- 2.0.24 2004/09/29
2890 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2891 does not require white-space before and after the dash in a range, e.g.
2892 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2895 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2896 due to new GCC removing "redundant" code.
2898 Added yaz-client commands scanpos and scanstep that sets preferred
2899 position and step-size for scan.
2901 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2903 Added CCL utility ccl_qual_buf which parses one or more CCL
2904 spec lines in a buffer.
2906 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2907 of name and value - ignoring empty lines and comments.
2909 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2911 Added odr_get_element_path which returns current element path for an
2912 ODR handle. This utility is useful in error handling or user-defined
2915 Added ODR_PRINT utility odr_set_stream which is is a more generic
2916 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2917 to a write function and pointer to close function. The close function - if
2918 non-NULL - will be called during odr_destroy.
2920 Fixed bug in CCL parser where truncation char was not removed from
2921 right side when truncation=both was in effect.
2923 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2926 --- 2.0.23 2004/08/11
2928 Fix buffer overrun in CQL parser when dealing with proximity (%).
2930 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2931 to UTF-8/UCS conversion is now only based on codetables.xml.
2933 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2935 --- 2.0.22 2004/08/06
2937 Add support for more "commit changes" in ZOOM (uses Extended Services).
2939 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2942 Yet another small fix for configure of SSL.
2944 --- 2.0.21 2004/05/14
2946 Fix SSL libs for configure when --with-openssl=DIR is given.
2948 --- 2.0.20 2004/05/10
2950 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2952 SSL comstack now uses yaz.pem certificate file on server side
2953 by default. Certificate filename can be configured by calling
2954 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2956 Fix bug regarding multiple calls to ZOOM_connection_connect.
2958 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2960 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2961 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2963 ZOOM now allows inspection of X509 peer certificate for verification.
2964 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2966 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2967 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2968 as "modular" but it simplifies things.
2970 Added cs_get_peer_certificate to that returns peer X509 PEM.
2972 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2973 NULL if SSL is unavailable.
2975 Documentation about MARC decoding tools.
2977 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2979 --- 2.0.19 2004/03/30
2981 Rename CHANGELOG to NEWS to follow GNU style packing.
2983 Fix bug with missing initialization of member in init_diagnostics.
2984 This bug affects threaded version of GFS server.
2986 --- 2.0.18 2004/03/20
2988 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2991 Ensure zlib.dll is packed with Windows install.
2993 --- 2.0.17 2004/03/17
2995 Fix encoding of xsd:string to use text instead of CDATA.
2997 Fix endless loop in CQL parser with unbalanced ".
2999 Use a more compact way to store MARC-8 conversion tables.
3001 --- 2.0.16 2004/03/16 Debian only
3003 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
3006 Update CQL parser to use new CQL 1.1 modifiers for booleans and
3011 --- 2.0.15 2004/03/01
3013 Another fix for decoding of XML packed records.
3015 --- 2.0.14 2004/02/25
3017 Fixes for Chunked encoding. White space not ignored after length spec.
3019 Update NS and use default NS for SRW diagnostic elements.
3021 --- 2.0.13 2004/02/23
3023 Implement ZOOM_resultset_cache_reset which resets record cache.
3025 Implement ZOOM_resultset_sort which sorts a result set.
3027 Implement chunked HTTP transfer.
3029 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
3031 --- 2.0.12 2004/02/16
3033 Added member 'schema' to bend_explain_rr structure so that backend
3034 can specify explain record identifier. Defaults to Zeerex 2.0.
3036 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3038 --- 2.0.11 2004/02/16
3040 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3043 Added init command for yaz-client which sends "extra" init request.
3045 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3046 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3048 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3050 Make ZOOM error code for "invalid query".
3052 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3054 --- 2.0.10 2004/02/05
3056 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3059 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3061 Added option -p <file> to make Generic Frontend Server to write PID file.
3063 Added option -D to put Generic Frontend Server in background on its own.
3065 Make ZOOM C recognize option "password". If unset, "pass" is used
3066 (for backwards compatibility).
3068 Fixed a bug in Generic Frontend Server that could make it crash if a
3069 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3072 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3073 Must be issued before open, in order to be in effect.
3075 --- 2.0.9-6 2004/01/12 Debian/Windows
3077 Make the SRU server more picky WRT unknown params, etc.
3079 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3081 New YAZ client command, options, that sets Z39.50 options.
3083 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3084 options from a string of tokens (one token for each option bit).
3086 Update SRW diagnostic code messages.
3088 --- 2.0.9-5 2004/01/07 Debian/Windows
3090 Handle user defined stylesheet for SRW/SRU.
3092 --- 2.0.9-4 2004/01/06 Debian/Windows
3094 Fix bug in decoding of Content-Length.
3096 --- 2.0.9-3 2004/01/06 Debian/Windows
3098 Fix a bug with decoding of XML packed records.
3100 --- 2.0.9-2 2004/01/05 Debian only
3102 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3104 Fix bug in SRW/SRU diagnostics decoding.
3106 --- 2.0.9 2004/01/05
3108 Fixed bug in Generic Frontend Server which could drop records exceeding
3109 preferred message size. Reported and fixed by Irina Dijour.
3111 Fixed calculation of package size for structured records in Generic
3112 Frontend Server. Reported and fixed by Irina Dijour.
3114 Fixed namespace for SRW/SRU diagnostics.
3116 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3118 --- 2.0.8 2003/12/22
3120 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3121 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3124 CQL changes to reflect recent changes to the specification:
3125 * Documentation talks about context sets instead of index sets.
3126 * Documentation talks about indexes instead of qualifiers.
3127 * The CQL-to-PQF transformer's configuration file now uses
3128 "index.set.name = <attributes>" instead of the old form
3129 "qualifier.set.name = <attributes>". (Both forms are still
3130 understood but the latter is deprecated.)
3131 * CQL terms with no explicit index specified are now interpreted as
3132 cql.serverChoice instead of srw.serverChoice (which of course
3133 behaves exactly the same.)
3135 --- 2.0.7 2003/12/16
3137 MARC conversion can now generate ISO2709 output in another
3138 character set. yaz-marcdump uses this facility if you invoke it
3141 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3142 functions from there can be used from C++.
3144 --- 2.0.6 2003/12/04
3146 Frontend server now transfers memory from decoded packages to stream
3149 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3150 references to show up.
3152 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3153 the ZOOM Abstract API. The older names for the same options are still
3154 also supported for the benefit of old applications.
3156 ZOOM-C supports "implementationId" and "implementationVersion" options
3157 to go along with "implementationName". These allow the user code to
3158 specify identification strings to be sent to servers.
3159 Add OID for the new ExtLite attribute set.
3161 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3162 as requested/supplid by Ere Maijala <ere@atp.fi>
3164 For generic frontend server, reverse the order of
3165 "toolkit-supplied / application-supplied" strings sent as implementationId,
3166 Name and Version. Also, remove the spaces around the slash. This brings
3167 the GFS in line with the behaviour of ZOOM-C on the client side.
3169 Add function ZOOM_scanset_display_term.
3171 yaz-client shows scan displayTerm if present.
3173 Utility yaz-iconv is now installed by default along with the man page
3176 Extend configure check for OpenSSL to use pkg-config where available (such
3179 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3180 server to specify uid/gid/mask for socket using the format
3181 unix:[user=uid,][group=gid,][umask=mask,]file=path
3182 If file= is omitted the existing format is assumed, e.g.
3184 in which case the mask is 0666 (rw for everybody).
3186 Major restructure of YAZ source. All source in libyaz is in src directory.
3187 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3188 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3190 Added man page for utility yaz-marcdump (used to be called marcdump).
3191 yaz-marcdump is installed by 'make install'.
3193 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3194 of incoming package failed.
3196 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3198 Change prototype of odr_perror: add const to message string.
3200 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3202 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3203 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3204 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3205 DNS lookup. There should not be any compatibility problems with this
3206 assuming that blocking=1 or 0 is used.
3208 Fix bad reference in UNIX comstack in function cs_addrstr.
3210 Fix for compilation on AIX.
3212 The generic front-end server (server/seshigh.c) now supports returning
3213 Init diagnostics to the client in User-information-field, in
3214 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3217 --- 2.0.4 2003/09/04
3219 Allow any CQL relation (not just all,any,exact,scr).
3221 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3222 that features the same UI.
3224 Implemented command update0 in YAZ client which is equivalent to
3225 update but uses old of Ext Update ASN.1.
3227 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3228 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3229 Previously no OID was used for this info.
3231 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3232 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3233 returns 'malformed search term' otherwise.
3235 SortResponse member resultCount now set to NULL in sort handler of
3238 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3241 Add three new utility functions for translating OIDs between various
3242 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3243 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3244 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3245 char *oid_to_dotstring(const int *oid, char *oidbuf);
3246 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3248 Reverted modifications for ES Update definition for z_IU0Update
3249 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3250 is back to YAZ 2.0.2.
3252 String value attributes for CCL parser.
3254 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3255 which their FirstSearch server returns in Init responses, sometimes
3256 carrying useful diagnostic information when Init fails. This has the
3257 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3258 "z39.50/oclcui.asn", where its definition is somewhat different from
3259 what OCLC document on their web-site, as required to interoperate with
3262 Support for anonymous authentication in yaz-client. Use the command
3265 * Fix the OID of the Index Data-local "admin" Extended Service from
3266 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3267 the 1000, which indicates a locally-defined OID, was a mistake.
3269 --- 2.0.3 2003/06/20
3271 Fix CCL directive @case handling so that it affects string match for
3272 both CCL keywords and qualifiers.
3274 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3275 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3276 Decoder has been updated with ASN.1 changes as listed in
3277 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3278 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3279 z_IUUpdate, remains unchanged.
3281 ZOOM_record_get may now return a record in a specific character set.
3282 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3283 "from" is the character set of record as returned by target. "to" is
3284 the character set to be returned. If omitted, "to" is UTF-8.
3286 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3288 New ODR utility, odr_getelement, which returns name of element for
3289 which encoding/decoding failed.
3291 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3292 in cases where a required element was omitted.
3294 Bug fix: some MARC8 sequences were not converted.
3296 New ZOOM option "step" which specifies number of records to be
3297 retrieved in one chunk. Used in conjunction with "start" and "count".
3299 SRW support for yaz-client. Use scheme http: to use it, e.g.
3302 yaz-client no longer does (un)intelligent character set conversions
3303 by default. Can be enabled with charset and marc_charset commands.
3305 xmalloc trace fix for 64-bit systems such as DEC alpha.
3307 Solaris 2.6 compile fix.
3309 New function, cql_strerror() translates SRW error codes, as returned
3310 by cql_transform_error(), into human-readable English strings. Used
3311 in yaz-client diagnostics when appropriate.
3313 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3314 converts it into a type-1 query which is sent to the server. This
3315 makes CQL available for use with all Z-servers, as opposed to the tiny
3316 minority that can handle CQL queries themselves.
3318 --- 2.0.2 2003/04/28
3320 New Debian package layout similar to the Redhat Package layout.
3322 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3323 and search result respectively.
3325 --- 2.0.1 2003/04/25
3327 Redhat package is now several packages: libyaz (runtime libraries),
3328 libyaz-devel (development and documentation, and yaz (utility programs).
3329 Package spec file by Morten Bogeskov.
3331 New member 'schema' in struct bend_fetch_rr which the name of requested
3332 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3333 handler MAY set this to reflect the schema of the returned record.
3335 New member 'display_term' in struct scan_entry. GFS now sets member entries
3336 and allocates scan entries to be filled by user scan handler. In previous
3337 version, entries member was allocated by the scan handler. That still works,
3338 but the GFS will ignore member display_term - assuming it was NOT set by
3339 the handler. The fact that the GFS now allocates the entries both allows
3340 for new members and makes a scan handler easier to write.
3342 Fix CQL lex buffer overflow.
3344 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3345 SRU default recordPacking is string.
3347 SRU protocol support for frontend server.
3349 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3351 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3353 Added scan for the ZOOM shell (zoomsh).
3357 * String Identifers for Schemas (Amendment 5).
3358 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3359 Old definition for schema
3360 Odr_oid *schema; /* OPT */
3365 Z_InternationalString *uri;
3366 #define Z_Schema_oid 1
3367 #define Z_Schema_uri 2
3370 * resultCount parameter to Sort Response (Amendment 1).
3371 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3373 Support for SRW 1.0 over HTTP. This is an optional feature and
3374 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3377 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3378 on the same port. SRW SearchRetrieveRequests are mapped
3379 to bend_init,bend_search,bend_fetch,bend_close.
3381 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3383 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3384 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3386 ZOOM connections are SRW based if schem http is used for hostname
3387 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3388 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3390 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3391 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3392 distance=n, order=true/false, relation=le, prox unit=word. If
3393 n is omitted, distance 1 is used.
3395 Fixed problem with C compiler include path in wrong order.
3397 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3398 on Solaris. Patch from Ko van der Sloot.
3400 New MARC decode API. All new functions operate on a yaz_marc_t
3401 handle. The most important new functions are: yaz_marc_create,
3402 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3403 decode and destroy respectively. Decoder can produce formats
3404 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3405 include/yaz/marcdisp.h.
3407 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3408 to UTF-8, UCS-32, wchar_t or Latin-1.
3410 * Prototypes for yaz_iconv_-functions moved to separate header
3411 include/yaz/yaz-iconv.h.
3413 Make a few private functions 'static' in unix.c. This prevents
3414 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3416 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3417 are set when Init Response is received.
3419 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3420 but returns diagnostic set as well.
3422 New function yaz_strerror which is a portable wrapper for
3423 strerror/strerror_r/GetLastMessage.
3425 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3426 is returned for MARC. If type is "oai", then OAI MARC is returned.
3428 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3431 --- 1.9.2 2002/11/26
3433 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3435 Fix bad race conditions on SIGTERM and terminate gracefully in
3438 Move retrieval (data1) module to Zebra since nobody seems to be
3441 Add GRS-1 render for ZOOM using same format as yaz-client.
3443 --- 1.9.1 2002/10/05
3445 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3447 Fix broken ESpec handling in data1 module.
3449 SGML reader parses comments and makes them part of the data1 tree.
3451 Added several type casts so that YAZ compiles as C++ code.
3453 ZOOM didn't handle PDU encoding failures properly.
3455 Added more Bib-1 diagnostics (approved extensions).
3457 GNU configure: better check for iconv.
3459 More portable use of accept, getpeername. Check for socklen_t. Use
3460 int/size_t if socklen_t is not defined.
3464 PQF parser rejects bad queries - including those with extra
3465 characters in them. PQF parser used to silently ignore that.
3466 Cleaner API for PQF added, which allows you to get detailed
3467 error information for bad queries (see yaz/pquery.h).
3469 Fixed bug in ZOOM_record_get for type "database".
3471 Implemented mini iconv library supporting conversions between
3472 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3474 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3476 --- 1.8.9 2002/08/20
3478 Fixed ZOOM C record cache so that preferredRecordSyntax and
3479 elementSetName is used to check for already fetched records.
3481 --- 1.8.8 2002/08/02
3483 Added three members in bend_initrequest structure to facilitate
3484 character set negotiation.
3486 Fixed a bug in frontend server that could cause indefinite
3487 loops under rare conditions.
3489 Revised character set utilities (charneg.h) so that encoding
3490 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3492 For PQF, directive @term <type> sets term type for Scan/Search.
3493 Here <type> is general, string, numeric, null. The term type
3494 is inherited - just like @attr.
3496 New call odr_set_charset that sets character set conversion for
3497 international-strings on a ODR stream. Prototype is:
3498 int odr_set_charset(ODR o, const char *to, const char *from);
3499 The InternationalString is still represented as C string in YAZ
3500 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3501 won't). On the protocol level, you can use any encoding.
3503 Support for UNIX sockets in ZOOM.
3505 Solaris recv sometimes returns errno == ENOENT. It is treated as
3506 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3508 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3509 both client and server. Code by Morten Bogeskov.
3511 --- 1.8.7 2002/05/22
3513 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3514 that they can be used directly from Visual Basic. You must recompile
3515 your windows APP if you're using ZOOM.
3517 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3518 Commands "lang" and "charset" sets language and character set respectively.
3519 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3520 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3522 Attributes from multiple CCL fields may be OR'ed rather than merged
3523 using directive "@field or". Fields are still merged by default -
3524 equivalent to "@field merge".
3526 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3529 Fixed bug in zget for parameter ExtendedServicesResponse.
3533 --- 1.8.6 2002/03/25
3535 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3537 Client displays USR.1:SearchResult-1 (hits per term).
3539 Additional Search Info for search in Generic Frontend Server.
3541 Fixed CCL parsing of "field=s".
3543 WIN32 installer - using the excellent NSIS software from nullsoft.
3545 Fixed CCL parsing of "field = - <number>".
3547 Added function yaz_marc_decode that decodes MARC for line mode
3548 display or XML (similar to that used by JZKit).
3550 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3551 Z39.50. But ISO/ILL was, however.
3553 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3554 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3556 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3557 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3559 --- 1.8.5 2002/02/03
3561 New YAZ client features: Command completion and new commands:
3562 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3563 Code provided by Jacob Poulsen.
3565 New call oid_trav, that visits all registered OIDs via callback.
3567 Function ZOOM_record_get now returns const char pointer rather than
3568 void pointer. It saves a lot of type casts.
3570 For YAZ client, command "auth" now allows you to set authentication
3571 in IdPass style. It is enabled when three tokens are given - order
3572 is user, group and password.
3574 Fix memory leaks in MARC record handling for ZOOM.
3576 New option for YAZ client, -k <kilobytes> that sets
3577 maximum record size. Similar to -k option for generic frontend
3578 server and yaz-ztest.
3580 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3582 Prefix query parser reports "fail" when bad attribute set is given.
3584 Fix in MARC decoder. Proximity logging. Fix for attribute set
3585 in scan handler for server. Patches by Shigeru Ishida.
3587 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3590 Configure option --with-openssl=<dir> now works when a directory is
3591 specified. Patch provided by Morten Bogeskov.
3593 New option for YAZ client, -u <auth>, that sets authentication.
3595 ZOOM fix: error information was sometimes "missing", since error
3596 was cleared/reset too when it shouldn't.
3598 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3600 --- 1.8.4 2002/01/04
3602 Scan for ZOOM API. New object ZOOM_scanset. New functions
3603 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3604 ZOOM_scanset_destroy.
3606 New ZOOM function, ZOOM_connection_last_event, that returns type
3607 of last event (such as "receive data", "send data", "apdu received",
3610 New ZOOM option, schema, that specifies schema for retrieval.
3612 New CCL feature. Qualifiers can be aliases for one or more
3613 other qualifiers (if more than one is given, OR is used).
3615 ZOOM uses named result sets if target supports it.
3617 Two new YAZ client commands: . (dot, which sources a script of YAZ
3618 client commands), and ! (to execute shell command.). Implemented
3621 Working on Debian packages.
3623 --- 1.8.3 2001/11/19
3625 YAZ client enables named result sets only if target supports it.
3627 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3629 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3630 with key="host" to get same result.
3632 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3633 Function Z3950_resultset_record(s) returns references to records
3634 "owned" by resultset. To become owner use Z3950_record_clone.
3636 Function z_ext_record handles Extended Services. Thanks to
3639 --- 1.8.2 2001/11/12
3641 CCL Parser fix: ignore token comma when dealing with and-lists.
3643 Documentation updates for COMSTACK.
3645 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3646 Changed prototype Z3950_records. For some functions, int parameters
3647 were changed to size_t.
3649 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3652 New MARC decode/display function, marc_display_exl, which properly rejects
3653 non-ISO2709 records. YAZ client uses it.
3655 --- 1.8.1 2001/10/29
3657 Fix bug: local attribute set wasn't set correctly in PQF strings.
3661 * Old Z39.50 codecs no longer supported.
3663 Added ZOOM C binding. See http://zoom.z3950.org/
3665 Renamed states for COMSTACKs to avoid confusion with events.
3667 Implemented cs_look and proper cs_rcvconnect.
3669 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3671 Configure detects POSIX threads on OpenBSD.
3673 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3674 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3676 When error is returned from present handler, non-surrogate diagnostic
3677 is returned in present response (and fetch handler is no longer called).
3679 * Minor adjustments to pquery parser (PQF). Token characters may be
3680 escaped by using backslash (C-style).
3682 PQF parser allows string attribute values to be specified. For @attr,
3683 non-numeric characters after the equal-sign are treated as strings
3684 (e.g. @attr 9=title).
3686 CCL trunction character may be defined (@truncation in file)
3688 * function zget_ExtendedServicesRequest sets waitAction to
3689 waitIfPossible (was wait).
3691 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3694 CCL operator names may be set in field definition files (CCL_bibset).
3695 See ccl/bib1 for an example.
3697 Fixes in ASN.1 compiler for C++ compatibility.
3699 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3700 and "op_or" to avoid conflict with C++.
3702 Fixed problem with GNU readline detection on Redhat 7.0.
3704 Added step-size for Scan backend handler.
3706 Fixed bug that made the frontend server crash when no attribute
3707 set was specified for scan.
3709 Front-end server automatically switches to original working directory
3710 when installed as an NT service. Previously -w had to be specified to
3713 Added extended attributes for retrieval module (data1), so that data1
3714 records carry d1_readXML/SGML attributes. d1_read also supports
3715 null-data rules ( <tag/>)
3717 On UNIX when POSIX threads are available, a separate library libyazthread
3718 is created. Programmers should link with that library and the yaz library
3719 when using threads. The reason for the split was that some applications
3720 on Linux, such as Apache, doesn't work well when using shared objects that
3723 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3724 (or any frontend server) in SSL mode by specifying ssl: followed by
3725 address. Only tested on UNIX.
3727 Added feature for CCL module. Virtual structure s=al or s=ol generates
3728 and-list and or-list respectively instead of phrase search.
3732 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3733 log_mask_str. This was done to avoid name conflicts with other libraries
3734 (such as other PHP extensions).
3736 Added raw OID member for preferred record syntax (request_format_raw)
3737 and returned record syntax (output_format_raw) for backend fetch method.
3739 Config file yaz-config now accepts options so that it returns specific
3740 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3742 Shared library support for UNIX using GNU libtool.
3744 * Modified backend interface. Request/Response struct's replaced by
3745 one read/write C struct. For example bend_fetchrequest and
3746 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3747 Every handler - even search has to be registered in bend_init
3748 handler. This means that the YAZ library no longer refers to
3749 external functions and it makes it possible to make the whole
3750 thing a single DLL/SO.
3752 Added Segment handler for backend server.
3754 Added Zmbol/Zebra administrative functions to YAZ client.
3756 Threaded frontend server on UNIX (when POSIX Threads are available).
3757 Starting the server with option -T enables multi-threading.
3761 Added configure option --enable-comp/disable-comp to control use
3762 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3763 located in sub directory asn.
3765 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3766 in ${exec_prefix}/bin along with the other programs yaz-client and
3769 GNU automake used to maintain makefiles.
3771 Added several OID's.
3773 Changed retrieval module so that we can load records with no abstract
3774 syntax defined. Tagpaths in these records are fully composed of string
3777 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3781 On UNIX, the generated makefile now supports a proper 'make install'.
3782 The prefix can be set via GNU configure to set the install location
3783 (default is /usr/local).
3785 * YAZ programs client and ztest were renamed to yaz-client and
3786 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3787 locations, such as /usr/bin,/usr/local/bin,etc.
3789 * YAZ Header files were moved from include to include/yaz. YAZ Header
3790 files are referred to as include <yaz/log.h> rather than <log.h>.
3791 The YAZ include path (-I ..) is therefore the same as before. Programmers
3792 should update their #include statements or use -Ipath/include/yaz
3793 instead. The main motivation for doing this change is that YAZ header files
3794 can be installed in "standard" locations /usr/include,/usr/local/include
3795 without introducing conflicts, since ALL YAZ header files are stored
3796 in subdirectory yaz (under /usr/include for example).
3798 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3799 rather than project/workspace files. We switched because project files
3800 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3803 Changed name of logging function, logf, to yaz_log, to prevent name
3804 clash with some math-log functions. The YAZ header log.h defines logf
3805 to yaz_log (#define) so there should be no incompatibilities by this
3808 Added bend_start/bend_stop handlers for server. These handler are
3809 called on start/stop of server. For windows they are called whenever
3810 a service is started/stopped.
3812 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3813 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3814 in util/yc.tcl. The auto-generated C code structures are, in a few
3815 cases, incompatible with the old decoders. There are differences in the
3816 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3817 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3818 The preprocessor variable ASN_COMPILED is defined when the compiled
3819 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3820 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3821 wish to use the old encoders/decoders you can specify --disable-yc
3824 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3825 version so that it supports both new - and old version of DB Update
3827 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3828 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3829 change. The name parameter can be set to 0 in which no name is specified
3830 for the construction. The macros odr_implicit and odr_explicit sets name
3831 parameter to zero for the construction involved. New macros
3832 odr_implicit_tag and odr_explicit_tag are similar to the others,
3833 except that a name parameter is added. For programmers' that don't use
3834 ODR they probably only need to change the call to z_APDU and z_External.
3836 Added access control facility by interfacing the TCP wrapper library.
3837 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3838 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3839 name of the daemon and enables the access control as specified in
3840 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3842 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3843 den Dool <H.M.vdnDool@kub.nl>.
3845 Added reference ID parameter to most functions in server API - refer
3846 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3848 Changed name of ccl library to libccl.a (was ccl.a).
3850 Fixed bug in decoder for Explain (Category TargetInfo).
3852 Added support for GNU readline in client. Thanks to Jacob Poulsen
3853 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3855 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3856 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3857 IMPLEMENTATION! This change was made to the development version before
3858 the ZIG decided to retract the amendment. If any users MUST be
3859 compatible with the original Update definition, PLEASE CONTACT US, and
3860 we will include a separate definition corresponding to the old Update
3861 ES. Note that because of the change to the ASN.1 of the
3862 TaskPackageRecordStructure we cannot define a single structure that
3863 will support both versions.
3865 * Added const modifier to buffer parameter for some ODR/BER encoding
3866 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3867 completeWAIS, odr_dumpBER.
3869 Fixed bug in client.c which caused a crash when a scanResponse didn't
3870 contain positionOfTerm.
3872 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3873 * will cause an error in a client if a non-YAZ target sends both a
3874 * list of Scan entries and non-surrogate diagnostics.
3876 Retrieval module enhancements. Tag sets may be typed in the reference
3877 to it. From the .abs-file the "tagset" directive takes a third optional
3878 integer type for the tag set referenced. From a .tag-file the "include"
3879 directive takes a third optional type as well. The old "type" directive
3880 in the tag set itself is still recognized but acts as the default type
3883 Backend interface change. Individual Scan terms returned from bend_scan
3884 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3885 in include/backend.h.
3887 Retrieval module enhancements. Multiple tag sets and attribute sets may
3888 be specified in abstract syntax specs. Revised the error/warning for
3889 logging messages reported by the retrieval module when reading the
3892 Object Identifier system (oid_..) changed. The API is backwards
3893 compatible but the oid-routines now allocates new OID's when needed.
3894 Raw OID's may be specified in oid_getvalbyname.
3896 YAZ now uses GNU configure to generate Makefile(s).
3898 * Minor changes in some of the member names of DeleteResultSetRequest and
3899 DeleteResultSetResponse. See include/proto.h.
3901 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3902 and added member 'languages' in TargetInfo (which was missing).
3904 Changed the way attribute sets are handled in the retrieval
3905 module. These are now cached, just like the abstract syntaxes
3908 Changed YAZ so that it links with compiled ASN.1.
3910 Added Explain-schema definitions and mapping routines. The following
3911 Explain categories have been implemented: AttributeDetails,
3912 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3914 Fixed minor bug in Windows version of Server Library.
3916 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3918 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3920 Added EXTERNAL: UNIverse Resource Report (non-standard).
3922 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3923 ENUMERATED and SET OF.
3925 * Added 'const' to some of the char pointer arguments for the
3926 functions, data1_read_node, data1_getelementbytagname,
3927 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3930 Fixed bug in data1_insert_taggeddata - the last_child member of
3931 parent wasn't initialised.
3933 * Changed data1_read_record and data1_read_node so that the supplied
3934 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3935 doesn't refer to any parts of the "SGML"-buffer.
3937 Fixed bug in server library (Windows version of statserv_remove).
3939 * Changed code so that it compiles as C++. The type definition
3940 of Odr_fun which is a member of Odr_arm was changed. The result is,
3941 that an explicit typecast is needed for the fun pointer when
3942 using Odr_arm - as in:
3943 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3945 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3947 Implemented the new structured date and time definition as approved
3948 by the ZIG. Added schemaId element to the specificTag in Espec-1
3949 (also approved at the last ZIG). Thanks to RVDM.
3951 Added some Object identifiers (RVDM).
3953 Changed the Update Extended Service (RVDM).
3955 Added command "refid" to client which specifies referenceId for
3956 the following requests.
3958 Implemented extended service handling for server. See ztest.c
3959 for an example as well as backend.h. New handlers are registerd
3960 in the Init handler.
3962 * Changed interface for sort in server.
3964 Added new members to statserv_options_block. It allows a server
3965 to read options from another source than just the command line. Thanks
3966 to Charles Woodfield.
3968 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3969 renamed to zboolean. Some C++ compilers complained about the name.
3971 Minor changes to gils.abs. Added index 's' (sort) on title
3972 and date/time-last-modified.
3974 --- 1.4pl2 1998/1/30
3976 Fixed bug in server library regarding inetd mode (-i). This bug
3977 was introduced by release 1.4.
3979 --- 1.4pl1 1998/1/29
3981 Added sort facility in client and backend server interface.
3983 Fixed problem with dependencies in Makefile(s).
3985 Fixed bugs for encoders/decoders of extended services and
3988 Implemented sub-tree feature for schemas. Sub-trees are
3989 referenced in *.abs-files. See explain.abs for an example
3990 of the use of this feature.
3992 Modified bib1.att; local attributes for ANY didn't include
3993 ANY itself (only affects use of the retrieval module).
3995 Fixed bug in plain SGML reader in function data1_read_node:
3996 tags with prefix "var" was incorrectly interpreted as variants.
3998 Added feature "sub-schemas" to enable references to - and definitions
3999 of - group of elements.
4001 * Removed member parent from type data1_element (in data1.h).
4003 Implemented function odr_nullval() that returns the value of
4006 * Removed member num_children from data1_node (in data1.h).
4008 Made NT service interface part of the server library. The
4009 function statserv_main uses the NT service when required and
4010 calls the statserv_start / statserv_close routines.
4012 Routine zget_SearchRequest and zget_PresentRequest fills
4013 resultSetName/Id member with "default" instead of "Default".
4015 Fixed memory leak in server. Request queue member wasn't freed.
4017 Fixed nmem_exit so that memory is freed.
4021 Revised the CCL parser utility to be thread safe.
4023 Added function, oid_ent_to_oid, to replace the function
4024 oid_getoidbyent, which is not thread safe.
4026 * Added nmem_init and nmem_exit to initialize and release
4027 NMEM resources. Function nmem_init should be called once in the
4028 initial thread before NMEM/ODR is used. statserv.c and client.c
4029 have been changed accordingly. The change was necessary to make
4030 NMEM thread safe. The NMEM memory pool is shared amongst threads
4031 in a process. Unix-based applications will still work fine without
4034 Added NT Services interface for the the Z39.50 (statserv) Server.
4035 Refer to the ztest.c source on the usage.
4037 Windows 95/NT port using MSVC5.0. Project files are included in the
4040 * Defined new 'global' handle for the retrieval (data1) system. The
4041 new handled, data1_handle, describes the state of the data1 system.
4042 This handle is passed as first argument to virtually all
4043 data1 related routines. The functions data1_create and data1_destroy
4044 creates and destroys a data1 handle respectively.
4046 Added ODR encode stream member to all backend request structures
4047 init, search, scan etc. This stream should be used to allocate all
4048 memory used for the response when thread safe operation is needed.
4050 Changed the comstack utility, cs_addstr, to be thread safe. The
4051 returned hostname string returned by the function is now part the
4054 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4055 function. The cs_straddr takes a COMSTACK handle as argument, so this
4056 function must be used after cs_create and before bind/connect.
4057 This function is thread safe.
4059 Moved test server to 'ztest' directory - generic server code still
4060 in 'server' directory.
4062 Made prefix query (pquery.c) utility thread safe.
4064 Added new function modifier YAZ_EXPORT to 'export' public DLL
4065 functions when using windows (see include/yconfig.h).
4067 Added definitions to the OID database (util/oid.c) (RVDM).
4069 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4071 Added call to ccl_rpn_delete in client program.
4073 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4074 release of RPN structure.
4076 Added support for C++, headers uses extern "C" for public definitions.
4077 With input from RVDM.
4079 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4080 Thanks to Ronald van der Meer (RVDM).
4082 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4084 Added support for private extensions to the OID database
4085 (oid_setprivateoids()). Thanks to RVDM.
4087 Added optional, physical ANY (key replication)
4089 Fixed null-reference problem in GRS-1 output filter.
4091 Proximity operator added to Prefix Query Format (PQF).
4093 In test client command "base" accepts multiple databases.
4095 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4099 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4101 Smallish bug-fixes in the new encoders/decoders (explain).
4103 Bug fixed in DeleteRequest.
4105 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4107 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4109 Added SOIF syntax (using private OID for now) to retrieval module and client.
4111 Added Update extended service.
4113 Added SearchResult-1 additional info structure.
4115 Added optional CCL (ISO8777) interpreter as separate module. Available
4118 --- 1.2 1996/6/10 (1st anniversary release)
4120 Added Summary record syntax. Lightly tested.
4122 Added OPAC record syntax. Untested.
4124 Added ResourceReport service encoders/decoders. Untested.
4126 Fixed bug in z_Unit - wrong tagging on unitSystem.
4128 Fixed bug in the DiagRecs decoder.
4130 Added options for max PDU size and session timeout to frontend-server.
4132 Added documentation of query-language parsers and other supporting utilities.
4134 [frontend-server] Added Attribute set to the bend_scanrequest API.
4136 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4137 surrogate diagnostics were generated.
4139 [retrieval] Allow multiple local values for attribute.
4141 [retrieval] Allow multiple attributes per element in .abs files. index type.
4143 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4145 --- 1.1pl2 1996/4/10
4147 Minor changes, mostly specific to Zebra's requirements (retrieval)
4151 Repaired bug in frontend server when running multiple listening
4152 endpoints in dynamic mode.
4154 z_External() now won't break if a known, ASN.1 value comes encapsulated
4155 in an octet-string. The value will pass through unmodified in an Odr_oct.
4157 Added a bit of code to the demo client to decode & display
4158 ASN.1-structured records represented in the octet-aligned branch of
4159 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4161 Added z_ext_getentbyref() to the ASN module. Doc updated.
4163 * Completed the SCAN definition in the ASN module. This may break SCAN
4164 code based on older YAZ-versions at compile-time. The fix is easy -
4167 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4168 under the SCAN definition. Remember to initialize this, server-people.
4170 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4171 that this does not extend to ODR and ASN.
4173 Comstack allows insertion of established socket (primarily for
4174 inetd-operation of servers). Doc updated.
4176 Front-end server can now start from the inetd in TCP mode. Doc
4179 --- 1.0pl4 1996/1/24
4183 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4184 the rank and record number.
4186 Adjustments to the frontend server.
4188 Fixed diagnostic BER dumper. It ignored the file argument.
4192 Various changes to retrieval module.
4194 Changed the union discriminators of the protocol files from enums to
4195 ints paired with #defines.
4197 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4200 *Changed operator in the RPN structure to 'roperator', again to avoid a
4203 Fixed problems in Explain decoders/encoders.
4205 --- 1.0pl2 1995/12/6
4207 Memory bug in log module fixed.
4209 --- 1.0pl1 1995/12/5
4211 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4213 Bug in Explain DatabaseInfo module fixed.
4215 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4219 The shift to v1.0 signals that we now consider the *core* functionality
4220 of YAZ reasonably stable (the core being more or less equivalent to
4221 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4222 tested (Explain not at all - though that will happen soonish).
4224 Minor changes to code to support Windows port.
4226 Various minor changes after we're getting to use GRS-1 & co. more.
4228 Added Espec-1 format.
4230 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4231 of the protocol and it cannot be selected when encoding (maps into 'string'
4232 when decoding). Needed to talk to some servers.
4234 Demo client can request simple element set names.
4236 Added Diagnostic Format encoders/decoders.
4238 Added simple Close handling to frontend server (no hooks for resource
4239 reporting yet), and demonstration client.
4241 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4243 --- 1.0b3 1995/08/24
4245 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4246 handled incorrectly when records were requested in the searchResponse. This
4247 will only affect you if you use the frontend-server.
4249 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4250 Test-client will ask for and print GRS1. Ztest will return dummy records
4253 Added Explain encoders/decoders to the service-level API. Untested.
4255 Added Extended Services: Item Order encoders and decoders to the Service-
4256 level API. Untested. We could use a recent copy of the pertinent bits
4257 of the ILL protocol to add those bits.
4259 Added diagnostic format 1 encoders/decoders to the service-level API.
4262 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4263 odr_cons.c, which causes a more correct output.
4265 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4266 was always set to 0 when no records were requested in the searchRequest.
4268 * Added better external-handling. This shouldn't harm old code that
4269 *encodes* externals. It can break code that looks for a
4270 'single-ASN1-type' representation, since those types that are known
4271 are now decoded immediately. Look at the SUTRS sample code in
4272 seshigh.c and client.c. Documentation updated.
4274 Handling of structured records in bend_fetchresponse. Length -1 marks
4275 structured record, type is deduced from format field.
4277 --- 1.0b2 1995/06/27
4278 Fairly quick maintenance release to add SUTRS support.
4280 Fixed handling of SUTRS records in the demonstration client.
4282 * Added format field to the bend_fetchrequest and bend_fetchresponce
4283 structures of the backend API (frontend server). When the record is
4284 returned, the value of the format field is mapped to an OID. The
4285 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4286 of the record. The special value VAL_NONE in the bend_request means
4287 that no specific format was requested by the client. Documentation
4288 updated accordingly. Test server (ztest) will return a fixed dummy
4289 SUTRS record if your client requests SUTRS.
4291 Documentation updated accordingly.
4293 You can now set external libraries and RANLIB support in the top-level
4297 First public release.
