25 Fix yaz-client: semicolon terminates arguments YAZ-851
29 Windows: Bundle VC runtime exe YAZ-848
31 Omit Content-Type for HTTP requests to Solr YAZ-850
35 Fix rpn2cql: structure, relation problem for serverChoice YAZ-849
36 Problem was that for things mapped to cql.serverChoice the relation
37 would sometimes be omitted when it should not. Eg for relation "all".
41 Document zoom extraArgs YAZ-817
43 Fix ZOOM: crash extended services diagnostics YAZ-846
44 The immediate fix is to prevent ZOOM_set_dset_error from removing
45 current task from connection. This, however, has been assumed in a
46 number of places so this fix is rather large unfortunately.
50 Make yaz_log_reopen async-signal YAZ-845
51 Fixes potential dead-lock issue with YAZ_DAEMON_LOG_REOPEN flags for
56 CCL: new feature s=spl (split-list) that splits terms in a search into
57 sub-phrases of all sizes (from 1 up to the number of terms) with order
58 preserved. For 3 terms the CCL search
61 @or @or @or @and @and a b c @and "a b" c @and a "b c" "a b c"
63 Solr: don't set defType=lucene in URLs if extraArgs already defines it.
67 Add lock/unlock for YAZ log writes YAZ-843
71 Fix incorrect parsing of URLs @:9999/somebase&url=http://some.host YAZ-842

85 Allow Content-Type application/sru+xml YAZ-840
87 New yaz_xml_get_prop utility YAZ-839
89 Fix zebrasrv [warn] ir_session (exception) YAZ-838
91 Document itemorder-setname and list all ILL options
95 Extend get_org_info (snippets) to return original string YAZ-836
96 Two new functions have appeared: icu_chain_get_org_info2 and
97 icu_iter_get_org_info2 with a 4th parameter being a pointer
98 to the original string.
100 Fix tcpip.c compilation failure on VC9 YAZ-835
102 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
103 The icu_iter_get_org_info returns information based on string
104 as it appears on tokenize step.
106 --- 5.10.2 2015/03/13
108 Deal with excess bytes in HTTP response for keepalive YAZ-830
110 Refactor ssl_put and tcpip_put to one function YAZ-832
112 Refactor ssl_get and tcpip_get to one function YAZ-831
114 Fix SEGV yaz-client for HTTP decoding error YAZ-829
116 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
118 --- 5.10.1 2015/03/03
120 Fix test_sru.sh fails in pazpar2 YAZ-826
121 Unfortunately a regression occurred with YAZ 5.10.0 that would make
122 Pazpar2 fail for HTTP connections.
124 --- 5.10.0 2015/03/03
126 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
127 Introduce cs_create_host2 which returns if connection should be
128 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
129 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
131 Fix http proxy fails with yaz-client YAZ-824
135 Fix 0 ptr reference for OPAC records from XML YAZ-822
139 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
143 record conv: 'select' return org record if no x-path match YAZ-814
145 retrieval: pick matched element-set rule YAZ-813
147 Fix crash in record conv rule 'select' YAZ-812
151 record_conv: selection by X-Path YAZ-811
152 That's a new step in record conversion system (<select path=".."/>)
154 Document record render parameters for ZOOM - including base64
158 Fix application/x-www-form-urlencoded + empty YAZ-810
159 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
160 and empty content was supplied.
162 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
164 Fail hard if Bison is not found and is needed YAZ-808
168 Enable YAZ backtrace for programs YAZ-802
170 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
171 Libxml2 2.9.2, Libxslt 1.1.28.
173 Fix daemon: parent process stops before child YAZ-806
174 Try to fix the situation where parent process stops before
175 child has acknowledged it .. SIGUSR2 back!
177 daemon: log message when keepalive stops.
181 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
182 would make yaz-marcdump crash when from-character set was issued.
186 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
187 New function yaz_enable_panic_backtrace which enables backtrace
188 handler for current process. The handler will call backtrace always,
189 then gdb to provide as much detail as possible.
193 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
194 and ZOOM record render will inspect leader 9 and switch to UTF-8
195 (Unicode) if that holds 'a'. This changes behavior, but is considered
196 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
198 Fix cs_put may reconnect if send fails. YAZ-798
202 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
206 Extended comstack with outgoing IP YAZ-795.
207 For cs_create_host + cs_create_host_proxy the vhost may be followed
208 by a outgoing host/IP. Separator is blank.
212 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
213 linker error with yazpp on Windows.
217 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
219 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
221 0 ptr reference in handling Solr response with error YAZ-791
223 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
225 Fix documentation about --installa option YAZ-788
229 daemon: properly report when receiving SIGUSR2 from child YAZ-785
233 xmalloc: throw assert for clearly invalid calls to malloc and
234 improve diagnostics YAZ-783 YAZ-784
238 Stop building debs for Ubuntu raring, quantal, oneiric.
240 CCL YAZ-781: for multiple use attributes in a specification the
241 generated RPN will perform @or on each term.
242 For spec: term u=31 u=1016
243 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
245 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
247 CCL YAZ-779: combo qualifier should allow for forward references
249 Fix buildconf.sh, automake too old on centos5 YAZ-778
250 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
251 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
252 accepts it without a warning.
256 GFS: client_query_charset conversion YAZ-777
257 This is a feature for Z39.50 clients that sends queries that are not
258 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
259 encoding given to UTF-8.
261 Echoed SRU arguments support YAZ-776
262 This is achieved with new function yaz_srw_get_pdu_e.
264 ZOOM: expire times set for redis/memcached YAZ-772
265 For both redis and memcached option --expire=seconds sets expire
266 time for a result-set/search. Default time is 600 seconds (10 minutes).
270 No [rest of output is omitted] limit for yaz_log YAZ-774
272 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
274 For ICU testing, pass -o to yaz-icu. This will test the
275 icu_iter_get_org_info function.
277 Fix null ptr reference for freeReplyObject YAZ-773
281 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
283 RPM: do not build with libmemcached support. The libmemcached library
284 on CentOS 5/6 does not work reliably for us (redis to the rescue).
286 configure: only allow libmemcached version 0.40 or later. That's the version
287 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
288 that's not an option, consider redis.
292 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
294 Fix zoom+memcached: present request out of range YAZ-767
298 CCL: add new qualifier r=omiteq which will omit relation=equals
299 for ordered relations. This should be used in combination with either
302 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
304 Solr: simplify yaz_solr_decode_response
306 Solr: use different local var for string manipulation
308 Solr: Get rid of hardcoded limit of extra_args
310 Solr: encode lucene query type YAZ-736
311 Make sure the queries are treated as traditional "lucene", because that's
314 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
318 Build packages for Ubuntu Trusty Tahr 14.04 LTS
320 wrbuf_cstr: fix off by one error.
322 wrbuf_buf: make it always return non-NULL
323 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
327 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
329 zoomsh: offer option -a apdulog
330 As we're used to from yaz-client and GFS based servers.
332 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
333 existing setting apdulog takes effect.
335 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
340 Add re-entrant CQL/Solr/RPN query conversion functions.
341 The re-entrant functions are: cql_transform_r,
342 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
343 These have same functionality as cql_transform,
344 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
345 return the additional infomration as WRBUF to make them re-entrant.
347 Remove CQL to Solr conversion and base solr_transform_t on
348 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
349 data structure as cql_transform_t.
351 cql2pqf utility allows RPN to Solr conversion
353 Fix assert in ZOOM when http connect fails YAZ-757
355 --- 5.0.22 2014/04/09
357 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
359 wrbuf_cstr: make it thread safe YAZ-753
361 yaz_log_init_file may take fd=<no> to open log file at the FD given.
363 --- 5.0.21 2014/03/21
365 Offer new utility function zget_AttributeList_use_string.
367 New conversion step, solrmarc, for record conversion module.
369 --- 5.0.20 2014/03/13
371 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
372 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
375 --- 5.0.19 2014/03/10
377 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
378 The standalone ZOOM sort was completely broken since 5.0.13.
380 ZOOM: generate event Connect rather than None for partial connect
381 (in fact getaddrinfo resolving).
383 ZOOM: only supply clientIP for InitRequest. Rather than for all
386 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
388 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
389 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
390 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
392 New "Facets" section in the documentation.
394 --- 5.0.18 2014/02/27
396 Call exsltRegisterAll in yaz_init_globals, so that all applications
397 using YAZ will have EXSLT things enabled.
399 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
401 Update various URLs to the re-organized SRU pages at LoC.
403 --- 5.0.17 2014/02/26
405 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
406 introduced in 5.0.12.
408 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
409 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
410 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
413 --- 5.0.16 2014/02/25
415 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
417 --- 5.0.15 2014/02/24
419 Fix gcrypt not properly initialized YAZ-740.
421 --- 5.0.14 2014/02/19
423 Describe memcached option for ZOOM.
425 ZOOM: throw present request out of range again YAZ-739
426 Was removed in YAZ 5.0.13.
428 --- 5.0.13 2014/02/18
430 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
431 with localtime_r when threads + fork is used (such as Metaproxy).
433 yaz-config: quote some RHS values (that might include blanks)
435 zoomsh: shows SearchResult-1
437 zoomsh: sortby command
439 zoomsh: use proper list of connections and result sets YAZ-725
441 Avoid yaz_log in sigterm handler for GFS YAZ-737
442 Logging is still performed, but outside sig handler.
444 New ZOOM C feature: result-set caching with memcached. Example:
445 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
447 Remove SSL via OpenSSL support YAZ-732
448 Also deprecate two functions from comstack that aren't working with
449 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
451 Revert "Bison: use %name-prefix directive rather than -p option"
453 --- 5.0.12 2014/01/22
455 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
457 SRU GET/Solr base URLs may hold additional ?args YAZ-729
458 ZOOM option extraArgs already does this, though. It seems useful
459 when dealing with Solr targets to limit by filter, eg.
460 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
462 Remove #fragment for HTTP request encoding YAZ-730
464 Doc: Update list of DLLs/LIBs
466 Doc: update href link to Unix utils and Git.
468 --- 5.0.11 2014/01/15
470 ZOOM: fix "lost connection" problem with servers that uses both squid
471 and another proxy behind it that returns Location headers with relative
474 zoomsh: do not use readline for stdin (no tty) YAZ-724
475 Just use fgets in that case. If the user hits Ctrl-D a new-line
478 zoomsh: empty command ignored YAZ-723
479 rather than performing exit of zoomsh.
481 yaz-url utility offers option -v to enable verbose mode.
483 yaz_url uses yaz_check_location and offers verbose mode.
485 Add new function yaz_check_location.
486 This function gets an absolute URI from Location (HTTP redirect).
488 cookie API: introduce yaz_cookies_reset
490 Update cql.y for newer bison YAZ-720
491 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
492 longer supported. Instead one must use %lex-param and %parse-param .
494 --- 5.0.10 2014/01/09
496 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
499 rpn2solr: support truncation left(2), left&right(3) YAZ-718
501 Mention SRU version 2.0 in yaz-client man page.
505 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
510 Make cs_parse_host public.A
512 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
513 introduced in YAZ 5.0.6.
517 Fix buffer corruption for yaz-ztest record fetch.
521 Allow yaz-ztest to return user-defined records (one record per file).
522 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
524 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
525 Use the stream write instead of odr_printf which has a 4K tmp buffer.
527 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
531 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
532 can read and write this format. For record format JSON, yaz-ztest returns
533 MARC-in-JSON records.
535 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
536 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
540 Improve error reporting for ICU chains YAZ-707
541 Report config element+rule when ICU status is "failure".
543 ZOOM: stop fetching if present response has no records YAZ-710
544 Some targets return less records than their hit count would suggest.
545 This prevents ZOOM from continuing to fetch records if any present
546 response has 0 records in the response.
548 Ensure that GFS calls exit if any listener fails YAZ-710
549 Before, if XML config was in use, it would start the default
554 yaz-ztest: -V shows version (like yaz-client -V)
556 New iconv encoding: danmarc YAZ-692
558 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
560 daemon: only wait for immediate child rather than all children. YAZ-704
562 yaz-client: fix setting of SRU record schema. If scheme was unset, it
563 could lead to invalid memory reference.
567 yaz-ztest returns schema for MARCXML test records. SRU require that
568 recordSchema for records.
570 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
571 instead of non-surrogate diagnostic. This is a per-record failure.
573 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
574 may refer to multiple listeners now. Attribute listenref is a comma separated
577 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
578 option is given for GFS, the dirname of filename (for -f) is used
579 as prefix for options such as cql2rpn, ccl2rpn, etc.
581 Content-Type charset fixes YAZ-701 . Do not inspect charset in
582 Content-Type header for SOAP when decoding SRU. The payload (XML)
583 itself tells what encoding it is. In response, never supply encoding
584 in Content-Type. The response payload (XML) tells what it is (with no
585 encoding in XML it's UTF-8).
587 HTTP decoding: allow blanks in URL paths YAZ-700
591 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
592 and facets. Ensure recordData and recordSchema are always present in
593 record element, because they are required.
595 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
598 Simplify in a lot of places using odr_strdupn.
600 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
604 Increase various buffers in GFS's statserv_options_block
605 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
606 This change makes many type-casts redundant, and, thus simplifies code.
608 Remove last bits of WAIS support.
610 Remove member 'size' from Odr_oct.
612 Slim down the public part of 'struct odr'. Most elements are not part
613 of struct Odr_private.
615 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
616 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
617 In particular facets are supported in both client - and server side.
618 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
619 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
620 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
621 both request/response). This is what a search handler in the GFS
622 will see (regardless of whether operating in SRU mode or Z39.50).
624 Changes to the srw.h (SRU/Solr) definitions include:
625 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
626 (char*), which replace union query and query_type (int). This is because
627 SRU 2.0 supports a queryType parameter. This also means that, to carry
628 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
629 x-pquery=PQFstring (extention parameter). The extension parameter
631 - New element, packing, that has information about SRU
632 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
634 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
636 New element, packing, in Z_SRW_explainRequest.
638 New elements in Z_SRW_scanRequest, queryType and scanClause.
639 These replace query_type and scanClase untion. This is similar to what
642 --- 4.2.69 2013/10/01
644 GFS: log when closing down - at least SIGTERM YAZ-684
645 Also change formatting WRT PID logging a bit.
647 Improve display of MARC records with multi-byte subfield IDs YAZ-695
648 In some rare cases subfield identifiers are multi-byte characters.
649 This will try to deterime length of those and split accordingly.
650 This affects display in line mode as MARCXML/MarcXchange. The encoding
651 of ISO2709 is the same.
653 Change inp argument to const for yaz_read_UTF8_char.
655 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
657 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
659 Better check of marc leader info YAZ-691
660 Problem is that some systems generate MARCXML/MarcXchange with
661 funny headers. These will not work if encoded as ISO2709.
662 Some tests produce new output, due to updated warning messages
664 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
666 yaz-client: display MAB records YAZ-689.
667 Thanks for Heiko Jansen for this patch.
669 New utility z_get_HTTP_Response_server which allows both HTTP server name
670 and HTTP server URL to be given in response.
672 Debian: do not depend on obs tcl8.3.
674 Debian: do not depend on obs libicu36-dev.
676 --- 4.2.68 2013/09/23
678 GFS: pass additionalSearchInfo to search memeber search_input if
679 given. Otherwise pass otherInfo. Request for facets and other search
680 related things will be passed there in future versions of YAZ.
682 New ZOOM setting, authenticationMode, which allows authentication
683 paramters to be encoded in the URL rather than via HTTP Basic auth.
686 rpn2solr: fix nested AND/OR handling. YAZ-685
688 Add comparison routines for some Z-types, such as NamePlusRecord,
689 RPNQuery, Query, RecordComposition and OtherInformation.
691 --- 4.2.67 2013/09/19
693 Don't decode MAB as MARC. Just like we don't attempt to decode
694 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
696 CCL: allow quoted terms for date ranges. YAZ-681
698 Introduce ccl_parser_qual_search. This function makes old function
699 ccl_qual_search, from YAZ 2, available again.
701 Add yaz_facet_list_to_wrbuf. YAZ-683
703 --- 4.2.66 2013/09/11
705 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
706 schema was given for search. YAZ-675
708 Add Solr date range searches. YAZ-621
710 --- 4.2.65 2013/08/22
712 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
714 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
716 ISO2709/MARC parse most octet aligned records; not just those that
717 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
718 MARC parse more records instead of just dumping as is. YAZ-670
720 ZOOM: proper caching for variations of record schema. YAZ-671
722 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
724 --- 4.2.63 2013/07/17
728 --- 4.2.62 2013/07/11
730 New utility z_get_HTTP_Response_details - an extended version of
733 New utility yaz_url_get_error which returns error message of last
734 failed yaz_url_exec call.
736 yaz-url and url functions: allow max HTTP redirects to be controlled.
738 New functions yaz_file_glob2, yaz_xml_include_glob.
739 These functions takes a flags parameter, which, for now only controls
740 whether to fail inclusion of a non-existing file (without glob
741 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
743 --- 4.2.61 2013/06/20
745 For MARC XML parsing, allow record without leader. A fake/default leader
746 is inserted and a warning is tagged with the record.
748 ICU: fix leak in in icu_iter_get_org_info.
750 --- 4.2.60 2013/06/14
752 ICU: fix bug in icu_iter_get_org_info (un-init variable).
754 --- 4.2.59 2013/06/11
756 Implement z_HTTP_header_remove.
758 --- 4.2.58 2013/06/11
760 ICU: Disallow 0 ptrs for some ICU string utilities.
762 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
763 returns original tokens (before normalization).
765 CCL: avoid z39.58/regex truncation when not needed. Apply only the
766 conversion of those masks, when absolutely necessary.
768 CCL: configurable masking character - @mask. Default masking character
771 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
772 full response anyway, so a Transfer-Encoding header will obstruct the
775 --- 4.2.57 2013/05/15
777 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
778 picking a socket. Problem is that some systems has IPV6 support, but
779 we can't create sockets for them, so we pick AF_UNSPEC first.
781 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
782 use content_len to determine resulting Content-Length in HTTP response
783 and NOT Content-Length supplied in headers by user.
785 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
786 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
788 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
791 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
792 with big endian and unsigned char (by default).
794 --- 4.2.56 2013/04/26
796 Fix yaz-client connect (crash in 4.2.55).
798 --- 4.2.55 2013/04/26
800 Fix proxy/host problem for ZOOM that could occur if unix sockets
803 New Debian package libyaz4-dbg.
805 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
806 differently in tcpip_close.
808 --- 4.2.54 2013/04/17
810 Windows installer of YAZ includes YAZ4J as a component.
812 CQL: allow "extra terms" again, by default. Thus, the CQL parser
813 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
814 and earlier. CQL parser may operate in strict mode where queries
815 not conforming to the standard BNF are rejected (syntax error).
816 Whether the CQL parser operates in strict mode is controlled with
817 cql_parser_strict . Strict mode enabled with option -S for utilities
818 cql2pqf and cql2xcql .
820 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
822 --- 4.2.53 2013/04/10
824 New charset, MARC-8c, which is like MARC-8 but allows control characters
825 0x01 through 0x1F, except ESC to be passed through verbatim.
827 Fix a problem with duplicate sub field character in MARC output. Problem
828 happened only when output was MARC-8 encoded.
830 --- 4.2.52 2013/04/03
832 yaz-ztest: Use hash for fake hit count. Before, random number was used.
833 This is problematic for unit tests using yaz-ztest. This patch also makes
834 a hash for CQL queries. For RPN, any term with a leading digit will be
835 treated as pseudu hit count (to force any particular hit count by a client).
837 yaz-ztest: return unique MARC dummy records. Beyond record offset
838 24, the author surname is patched with offset to make all records
841 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
842 on system wide default (/proc/sys/net/ipv6/bindv6only).
843 @4 binds to IPV4 only. @6 binds to IPV6 only.
845 Update CQL API documentation a bit
847 CQL: don't accept extra terms for queries. Makes the CQL parser
848 stricly conformant to the standard.
850 --- 4.2.51 2013/02/12
852 GFS: scan handler gets extra_args from request and may return extra
853 response data . That's for SRU only.
855 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
857 --- 4.2.50 2013/01/30
859 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
861 OPACXML: sync spelling of availabilityDate in XML to that of Schema
862 opaxxml.xsd. The schema had the correct spelling of this member always.
863 The ASN.1 was mis-spelled and still is (API change) - we are
864 not changing this. However, the OPAC to XML conversion had yet
867 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
870 New function, z_ext_record_oid_nmem, which is similar to
871 z_ext_record_oid but takes NMEM rather than ODR
873 --- 4.2.49 2013/01/18
875 ICU: New conversion element 'join' which joins tokens into one
876 with a custom character given by rule attribute.
878 --- 4.2.48 2013/01/10
880 New GFS search member: present_number. This is a hint to the
881 search handler how many records are going to be fetched immediately
882 following search. There's no guarantee that it's going to be the case,
883 since it depends on hit count (for Z39.50 piggyback) and whether errors
886 Make a few functions static (private). The functions getbyte_stream,
887 ungetbyte_stream and yaz_gets are now private. They were never declared
890 yaz-marcdump: exit(5) for serious decoding errors
892 ISO2709 decoding: be more picky WRT header
894 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
895 was only used as to indicate that next-result-set-position should be
897 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
898 Based on patch from Ashley Sanders.
900 Make some functions static/private in PQF parsing. Those functions were
901 never declared in a public header and so should not be in use by
902 applications based on YAZ.
904 --- 4.2.47 2012/11/23
906 ZOOM: special options to control APDU logging.
907 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
908 logging of APDUs until "saveAPDU" option is set again. If logging is
909 already enabled the effect is that current APDU buffer is cleared.
910 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
911 logging (default behavior on new connection).
912 The APDUs sent/received can be obtained by using
913 Using ZOOM_connection_option_get(c, "APDU") or
914 ZOOM_connection_option_getl(c, "APDU", &l).
916 GFS: relay implementation_version from backend
917 From 3.0.40 and later, implementation_version from backend was
918 not used in init response at all.
920 --- 4.2.46 2012/11/15
922 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
923 mode at all. Probably never did.
925 Make a new version of ztest.pem that, at least, is not expired.
927 --- 4.2.45 2012/11/13
929 Fix description of CCL directive 'case'.
931 More tight checking of form arguments (yaz_uri_to_array). Makes
932 YAZ better at rejecting big and/or bad POSTs.
934 SRU decoding does not report more than up to 10 invalid arguments.
936 rpn2cql: less quotes in generated terms. Semantics unchanged, but
937 it's prettier this way.
939 --- 4.2.44 2012/10/25
941 New utility yaz_decode_init_diag. Defined in proto.h.
943 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
944 given for unix local socket.
945 The COMSTACK string for doing so is:
948 unix:/myfile:tcp:localhost:9999/mybase
949 unix:/myfile:localhost:9999/mybase
950 unix:/myfile:http://fakehost/mybase
952 debian: Use dpkg-buildflags in build process.
954 --- 4.2.43 2012/10/19
956 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
957 global's SRU service uses a recordPosition scheme starting from zero.
958 First record's position should be one
959 according to the standard.
961 --- 4.2.42 2012/10/18
963 Allow more namespaces for SRU. This is to allow, for example, an
964 incorrect namespace returned from server
965 http://services.igi-global.com/sru .
967 Minor fixes for compilation on Windows.
969 --- 4.2.41 2012/10/11
971 daemon: log total number of bad signals from child on stop so that it
972 is more easy to spot problems with child worker processes.
974 retrieval: empty backend name attribute omits element set
975 from being used in retrieval.
977 --- 4.2.40 2012/10/04
979 Implement Solr sort strategy "solr", similar to sru11 sorting.
980 This will implement the correct parameters on Solr requst to do
983 --- 4.2.39 2012/09/28
985 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
988 MARC: Extra/missing indicator handled for MARCXML.
989 The indicator length is given in header and is the same for the
990 whole record. If attributes ind1, ind2 are missing, then content
991 character defaults to blank. Extra indicator attributes (beyond)
992 indicator length are treated as an error.
994 Reformat: delete trailing whitespace
996 --- 4.2.38 2012/09/17
998 MARC: fix non-ASCII characters for leader. This is to ensure we can
999 generate XML in UTF-8.
1001 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
1002 in one node with structure word.
1004 --- 4.2.37 2012/09/04
1006 yaz-json-parse: JSON output may be pretty printed by using option
1009 Increase default value of max message for Z39.50 Init for GFS, ZOOM
1010 and yaz-client. Old value was 1 MB. New value is 64 MB.
1012 --- 4.2.36 2012/08/22
1014 yaz-client: don't display bogus records from SRU servers. Some SRU servers
1015 return more records than given by *maximumRecords*. Skipping those in
1018 record_render: simplify buffer return handling and fix at least one bad
1019 memory reference, that broke the test_embed_record sometimes.
1021 Allow http://user:pass@host notation for yaz_url_exec.
1023 zoomsh: allow shell command to be executed. Via the system(3) call.
1025 yaz_poll: Allow num_fds == 0
1027 yaz-client: fix bad encoding of "itemorder item". The itemorder
1028 item <no> - command forgot to use length of encoded Item Request
1029 package. Error present since YAZ 3.
1031 yaz-ztest: fix bad usage of session handle. Bug was introduced when
1032 result sets were saved (271a9c83).
1034 SRU recordPacking: guess record packing in response rather than looking
1035 at the recordPacking element which, OF COURSE, changed semantics in SRU
1038 Decode SRU 2.0 responses. The official namespace for responses, according
1039 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
1040 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
1041 nature.com's server, however, usee namespace
1042 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
1043 we are now using a glob-expr to match up the namespace. ZOOM C and
1044 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
1045 I can not find a single real example showing the "real" namespace in
1046 the documentation from OASIS. The namespace for requests is different
1047 from responses, but this is not added to YAZ yet, when we don't encode
1050 --- 4.2.35 2012/06/26
1052 zoom/record_render: add support for Base64 decoding fo MARC records
1053 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1054 which will decode base64 + ISO2709 marc-8 encoded material from text node
1057 --- 4.2.34 2012/06/07
1059 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1060 and ZOOM_resultset_facets_names.
1062 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1065 Change APDU dump printing to avoid long leading blanks. For levels 16
1066 or larger the level is shown and the indentation is truncated but
1067 recursed with modula 8. This makes it still reasonable easy to read
1068 - even for nested BER dumps.
1070 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1071 return 0 (incomplete package) in case where the BER package was
1072 considered too nested (return value of -2).
1074 dumpber: lines of level 15 are not indented further. Two spaces per
1075 indentation; indentation 15 or more is indented to a fixed indentation
1076 and augmented with a level=<no> indication.
1078 zoomsh: increase max size of command+args
1080 GFS: No limit in RPN buf size in CQL to RPN conversion.
1082 --- 4.2.33 2012/05/09
1084 New function for daemon utility, yaz_daemon_stop .
1086 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1088 --- 4.2.32 2012/04/25
1090 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1091 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1093 --- 4.2.31 2012/04/23
1095 YAZ daemon utility relays SIGUSR1 to child process.
1097 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1098 would result in en empty database list - which in turn would result in
1099 encoding failure for search.
1101 Fix reading beyond string in yaz_sort_spec.
1103 --- 4.2.30 2012/04/11
1105 Add two new SRU diagnostics:
1106 236: Access to specified database denied
1107 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1109 Document the very useful ZOOM-C option "apdulog".
1111 CQL to RPN: term may be passed through verbatim. This is enabled with
1112 truncation.cql . The assumption being that the term is already CQL.
1114 --- 4.2.29 2012/03/20
1116 record_conv: leader spec may be given for marc element.
1117 The leader spec is given as attribute leaderspec for element marc.
1118 For example to convert a MARC21 record from MARC-8 to UTF-8:
1119 <marc inputformat="marc" outputformat="marc"
1120 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1122 record_conv: allow user-XSLT params. For example:
1123 <xslt stylesheet="MARC21slim2DC.xsl">
1124 <param name="myparameter" value="myvalue"/>
1125 <param name="otherparameter" value="othervalue"/>
1128 record_conv: fix error handling for missing marc charsets.
1130 CQL: fix extra terms in wrong order.
1132 --- 4.2.28 2012/03/06
1134 record_conv: modify new API for conversion types. The conversion types
1135 may be passed in new functions yaz_record_conv_configure_t and
1136 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1138 Avoid mixed statement/variable declare; fixes compilation with Visual
1141 --- 4.2.27 2012/02/28
1143 Add non-standard SRU diagnostic: 235: "Database does not exist".
1144 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1145 Update SRU to Bib-1 diagnostic maps accordingly.
1147 CCL: add two new diagnostics for unsupported masking. The new
1148 diagnostics are: "Embedded truncation not supported" and
1149 "Single charcacter mask not supported".
1151 --- 4.2.26 2012/02/23
1153 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1155 --- 4.2.25 2012/01/11
1157 Build YAZ for Ubuntu Oneiric.
1159 CCL: allow parantheses for proximity operands. For example CCL query
1160 (a) % (b) is now allowed.
1162 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1163 marked dead, rather then being destroyed. If not, the session memory is
1164 being free'd before the search/scan handler is finished. Also destroy
1165 'request' memory in request_release rather than in various places,
1166 which resulted in leaks from time to time.
1168 --- 4.2.24 2011/12/21
1170 cql_sortby_to_sortkeys: honor sort prefix.
1172 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1173 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1174 The rpn2cql family of functions now always returns quoted CQL terms.
1176 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1178 --- 4.2.23 2011/12/15
1180 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1181 sequence is treated as one. For example, &&a=b&&&c& is identical to
1184 --- 4.2.22 2011/12/05
1186 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1187 APDUs for a connection to a WRBUF.
1189 --- 4.2.21 2011/11/23
1191 Fix cql_sortby_to_sortkeys. Completely broken before.
1193 Make CCL's @truncation work again.
1195 --- 4.2.20 2011/11/09
1197 New ZOOM connection setting: tproxy. It's like proxy, but does not
1198 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1199 to set resolved address + port for a connection outside ZOOM itself.
1201 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1203 --- 4.2.19 2011/11/07
1205 Fix uninitialized variable in Solr spell support (could cause SEGV
1206 for SRU response decoding).
1208 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1209 back-end's addinfo through into the ZOOM response addinfo.
1211 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1212 they are separated by a colon and a space rather than simply
1215 --- 4.2.18 2011/10/28
1217 Add support for Solr spell-checking/suggestions through ZOOM.
1218 If a Solr target has been configured correctly for spelling-checking
1219 and suggestions, these will now be returned on the ResultSet option
1220 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1222 --- 4.2.17 2011/09/28
1224 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1225 with a flag whether to substitute escape sequences or not.
1227 --- 4.2.16 2011/09/22
1229 Fix nmem_strsplit_escape to substitute escape char properly.
1231 New option for zoomsh -e , which makes it abort on first error and
1232 return process exit code to indicate success/failure.
1234 YAZ options utility supports special option -- which makes all it treat
1235 all following arguments as non-options.
1237 --- 4.2.15 2011/09/16
1239 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1240 searched if absolute filename is given.
1242 Fix conv_xslt() error-reporting when stylesheet is not found.
1243 (The value of fullpath is meaningless in this situation.)
1245 --- 4.2.14 2011/09/07
1247 Fix problem in CQL sort node creation: un-initialized memory.
1249 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1250 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1251 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1254 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1255 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1257 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1258 will make it possible to use both single-character mask (#) and wildcard (?)
1259 in CCL . Throw diagnostic for left truncation because that is not supported
1262 --- 4.2.13 2011/09/01
1264 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1265 cases using escapes (\-sequences) and masking.
1267 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1268 would result in a read one byte beyond string.
1270 rpn2ccl may use Z39.50 masking for terms (t=z).
1272 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1274 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1275 not --cppflags (which seeems like an error in icu-config).
1277 --- 4.2.12 2011/08/27 RPM package only
1279 cql2ccl: fix conversion of terms: operator characters were not
1282 --- 4.2.11 2011/08/25 RPM package only
1284 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1285 CCL parser will map both # and ? to their regular expression
1286 quivalents (. and .*).
1288 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1289 of reserved CQL characters.
1291 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1292 is, so that they are passed through.
1294 --- 4.2.10 2011/08/24
1296 ZOOM SRU mode: more aggressive re-connect.
1298 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1299 made available as a utility function, declared in <yaz/logrpn.h>
1301 rpn2cql_structure() supports proximity nodes (except that the Type-1
1302 proximity node's "exclusion" binary is ignored, as there is no way to
1303 express that in CQL). Fixes bug #4564.
1305 --- 4.2.9 2011/08/18
1307 Fix SEGV that could occur if set command of zoomsh was given without
1308 value (2nd argument).
1310 Fix SEGV that could occur if unsupported transport was given for
1311 COMSTACK - say https (when SSL was unavailable).
1313 Build yaz-url on Windows too.
1315 --- 4.2.8 2011/08/11
1317 New utility to get web content. Header is url.h. A command line tool
1318 yaz-url is part of the distribution and packages.
1320 Fixes for SSL COMSTACK (when gnutls is in use).
1322 New functions yaz_base64{encode,decode}. Header is base64.h.
1324 --- 4.2.7 2011/08/03
1326 ZOOM C includes HTTP response buffer as additional info if it fails
1327 to decode the SRU response.
1329 Make wrbuf_json_puts available.
1331 --- 4.2.6 2011/07/28
1333 zoom: throw diagnostic for invalid value for option "sru". Before a
1334 bad SRU request was sent.
1336 Adding new utility wrbuf_vp_puts.
1338 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1340 --- 4.2.5 2011/07/21
1342 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1343 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1344 redirect was used at the same time.
1346 MARC line mode decoding: be less picky about length given - first
1347 5 digits of header that is.
1349 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1351 Changes to decoding of SRU records: a record with recordPacking=xml is
1352 modified with a new root element <yaz_record> if the recordData contains
1353 multiple children elements. This is to make the record XML parseable
1356 RPN to Solr conversion: encode special characters.
1358 Generic Frontend Server: fix uinitialized member, stepSize.
1360 --- 4.2.4 2011/06/21
1362 Fix a bug in SRU decoding of records.. The database records stored
1363 had un-initialized memory, but it would only be seen with yaz_record_render
1364 and type_spec="ext" .
1366 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1368 --- 4.2.3 2011/06/17
1370 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1372 --- 4.2.2 2011/06/10
1374 Add new utilities to convert from CQL to CCL . These utilities have
1375 prefix cql_to_ccl defined in cql.h.
1377 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1378 lead to memory heap corruptions when ICU utilities were in use.
1380 --- 4.2.1 2011/06/07
1382 Make compilation work without Libxml2.
1384 yaz-client: remove redundant blanks in display of searchResult-1 term
1387 --- 4.2.0 2011/05/18
1389 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1390 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1392 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1393 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1394 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1395 Note that the CQL sortby spec is only converted when the GFS is already
1396 converting from CQL to RPN (cql2rpn element).
1398 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1399 specify whether to collapse delimitors or not. The existing nmem_strsplit
1400 do collapse (collapse parameter = 1).
1402 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1404 Rename internal func yaz_use_attribute_create. While non-static, this
1405 function is not declared in a public header.
1407 --- 4.1.7 2011/03/15
1409 Add -lCrun when linking with ICU on Solaris.
1411 More quicks character set conversions for OPAC records.
1413 --- 4.1.6 2011/03/10
1415 fix problem with record_render: records were converted (character set
1416 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1418 --- 4.1.5 2011/03/08
1420 SRU: add methods for handling DADS SRU-proxy facets.
1422 Separate OPAC record character set for ZOOM_record. yaz_record_render
1423 allows a character set given as charset=from/opacfrom,to where 'from' is
1424 the character set of a bibliographic record, 'opacfrom' is character set
1425 of OPAC record and 'to' is the target character set.
1427 --- 4.1.4 2011/02/21
1429 yaz-client: show may XML format records. Command show followed by 'format'
1430 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1433 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1436 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1438 --- 4.1.3 2011/01/27
1439 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1441 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1442 this package can be distinguished from other vendors.
1444 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1445 as determined by configure
1447 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1449 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1450 returns no error and no record, the present request is considered
1451 partial (only a subset of the records could be returned by backend), and
1452 so it is appropriate to set Present Status to partial-4.
1454 --- 4.1.2 2010/11/02
1456 Move yaz-config man pages to section 1.
1458 More documentation about Solr.
1460 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1461 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1462 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1463 peers on some Linux systems. However, in general that does not work
1464 so YAZ can not rely on that to work. Debian changed behavior in this
1465 respect from Debian lenny to Debian squeeze (still testing as of Oct
1467 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1469 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1471 --- 4.1.1 2010/10/05
1473 Fix yaz-config output: echo_source not set correctly by configure.
1475 --- 4.1.0 2010/10/05
1477 Solr Web Service support for yaz-client and ZOOM.
1479 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1481 --- 4.0.12 2010/08/17
1483 Z39.50 facet support. Facet specifications are passed for search in
1484 other-information with ASN.1 as defined in facet.asn and OID
1485 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1486 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1487 3 is limit (number of entries to get in response). yaz-ztest returns
1488 dummy facets if a client asks for them.
1490 --- 4.0.11 2010/07/09
1492 CCL fixes: bug 2895 and bug 3539.
1494 GR1-display: add comma in display - was removed by mistake in
1497 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1499 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1501 --- 4.0.10 2010/06/18
1503 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1504 result set from a connection. The result set will be on its own
1505 thereafter; no operations on it will perform retrievals from a target.
1506 Only cached copies are returned.
1508 ZOOM C:fix case for HTTP servers responding with Connection:close.
1509 Ensure that if there is a current task it is resumed (like fetching
1510 more records in a result set) . Bug #3484.
1512 PQF parser: use odr_atoi for Odr_int (not atoi)
1514 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1515 values that contain any non-digits are treated as string attributes
1516 (previously decoding only checked for leading character ([0-9]). PQF
1517 encoding: attribute string values are not surrounded by double-quotes.
1519 --- 4.0.9 2010/05/21
1521 New utility for managing threads - thread_create.h.
1523 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1524 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1525 but YAZ' implementation do.
1527 Fixes for yaz_cond-functions on Windows 7.
1529 DLL export more symbols.
1531 zoomsh: show record do NOT render opac.
1533 Remove *.la files from Debian and RPM packages.
1535 --- 4.0.8 2010/05/11
1537 Debian package libyaz-dev depends on libgnutls-dev again (was
1538 removed in YAZ 4.0.6, but due to Libtool it is still needed
1539 even though yaz-config do not list libgnutls libs).
1541 ZOOM: Use only one WRBUF for returning string results for
1542 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1544 ZOOM: ZOOM_connection do not use a shared pointer to
1545 ZOOM_resultset after ZOOM_resultset is destructed by
1546 user. Reverts to YAZ 4.0.4 behavior.
1548 --- 4.0.7 2010/05/04
1550 record-conv: fix problem with at least one XSL conversion -
1551 due to probably incorrect usage of XML XSL documents.
1553 --- 4.0.6 2010/04/29
1555 Fix yaz-config for static mode and the use of SSL (gnutls).
1557 --- 4.0.5 2010/04/29
1559 Forward decl timeval struct in mutex.h and gettimeofday.h.
1561 yaz-config: fix 'static' mode linking.
1563 --- 4.0.4 2010/04/28
1565 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1566 are wrappers for pthreads or Windows. For Windows these are put in
1567 a separate DLL: yaz_cond4.
1569 libyaz.la (whole source) is compiled with thread. If thread support
1570 is enabled enabled, all source of YAZ is compiled with treading support.
1571 This allows core utilities such as yaz_log to use thread facilities.
1572 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1573 thread utilities. This commit moves mutex utilities (mutex.c) from
1574 libyaz_server.la to libyaz.la.
1576 yaz-json-parse displays leading text until error.
1578 --- 4.0.3 2010/04/09
1580 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1581 patch from Giannis Kosmas.
1583 SRU: no longer URL encode SRU database. The URL for an SRU server is
1584 a URL and such is alreeady encoded - at least when given with leading
1585 http:// or https://. This reverts behavior to YAZ 3.0.50.
1587 Support for new MARC XML notation TurboMARC which like MARCXML is a
1588 complete representation of MARC/ISO2709.. This one, however, is more
1589 compact and allows for faster processing with XSLT. TurboMARC can be
1590 used in the marcdisp.h API, from the yaz-marcdump utility and from
1593 yaz-ztest can be configured - via the database - to perform certain
1594 delays when it performs operations search, present and single record
1595 fetch. This allows testers to make yaz-ztest act as a real or even slow
1596 Z39.50 server. Refer to the yaz-ztest man pages for details.
1598 --- 4.0.2 2010/03/09
1600 wrbuf_destroy allows NULL WRBUF passed to it.
1602 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1604 Add ZOOM_connection_close.
1606 No fixed size buffers for ZOOM shell - bug #3257.
1608 tstodr: make it work on s390 platform.
1610 New icu iterator-functions. The new icu_iter-functions makes it possible
1611 to use ICU chains from many threads.
1613 yaz-client: better syntax check for show command.
1615 --- 4.0.1 2010/01/26
1617 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1620 New simple local-file XML include facility which allows file glob-patterns.
1621 Refer to yaz/xml_include.h.
1623 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1626 ZOOM_record_get supports new parameter "format" which makes it format XML
1629 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1630 JSONText in ECMA-262) is JSONValue, not JSONObject.
1632 --- 4.0.0 2010/01/20
1634 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1635 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1637 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1638 POSIX/Unix builds .so with major version 4.
1640 Remove old LOG_-defines from log.h. They have been obsolete and
1641 undefined by default for the last 5 years.
1643 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1645 GFS: Remove socket (int *fd) from search_rr handler. The socket
1646 descriptor ptr is a facility that allowed a search handler to supply
1647 a socket which would serve as a callback - when search was complete.
1648 This facility has now been in use for years.
1650 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1651 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1652 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1653 returns 'const char *' rather than 'char *. The returned string is
1654 read-only and should not be modified by applications. COMSTACK cs_close is
1655 now a void function - it no longer returns int. No applications check for
1656 the value and the implementations has always returned 0.
1658 ZOOM: use size_t for scan hit counts and str size. Functions
1659 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1660 occ (hit count) and len (string length) are now of type size_t pointer
1661 rather than int pointer. This is to be able to represent large hit counts
1662 and to also just to use the proper type for string length (strlen result).
1664 New JSON parser. Refer to include/yaz/json.h .
1666 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1667 Used to be int in some cases. Many wrbuf_-functions used to return an int
1668 indicating some length.. These return values were never used. And so they
1671 ODR: odr_malloc, odr_total now takes size_t for size.
1673 clone_z_type: fix leak; occurred for encoding failures.
1675 --- 3.0.52 2009/12/03
1677 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1678 bug was introduced in 3.0.51.
1680 --- 3.0.51 2009/12/02
1682 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1684 tcpip comstack: fix leak for getaddrinfo.
1686 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1687 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1688 Decoding of SRU "path" database is performed by private function
1689 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1690 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1692 yaz-client: honor base command for SRU. Change when database setting
1693 is applied for SRU and ensure it is kept when a connection is reset.
1694 Change also the way errors are displayed or SRU (decoding of packages).
1696 --- 3.0.50 2009/11/02
1698 Add support for extra request / response data for SRU codecs and GFS.
1699 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1700 for extra data response buffer and length. For the GFS, both request
1701 and response data (XML) is carried in extra_args and extra_response_data
1702 for the search handler. Patch by Ko van der Sloot.
1704 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1705 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1706 10010). This fixes bug #2113.
1708 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1709 cmdfile included a 'quit' command that would result in a memory violation.
1711 --- 3.0.49 2009/10/01
1713 Make a number of functions defined in xmlquery.c static. These have
1714 never been declared in a public header file (yaz/xmlquery.h) and was
1715 made public by mistake.
1717 Improve speed of character conversions (iconv utilities). This makes
1718 conversions from MARC-8 faster.
1720 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1721 unless type desired is "raw". This will prevent type "xml" from
1722 returning ISO2709 .. Which obviously can not be XML parsed.
1724 Fix memory leak in ZOOM that would occur if option apdulog was used
1725 on a re-used connection.
1727 Frontend server logs HTTP requests.
1729 Frontend server now sends Z39.50 close when it times out (sesssion has
1730 been idle for too long). Versions 2.0.30 and earlier also sent close.
1731 But due to a mistake this was disabled in all versions after that, i.e.
1732 the server would just close the socket immediately.
1734 yaz-client emits a better message when receiving an unrecognised
1735 userInformationField.
1737 Skip zero-length subfields when decoding ISO2709. This rare case happens
1738 if a record has two FS characters in a sequence. Without this patch
1739 there would be a reference beyond char array in using_code_len fragments
1742 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1744 --- 3.0.48 2009/08/28
1746 The show command offered by the zoomsh command now takes a 3d optional
1747 parameter type which is what is passed to ZOOM_record. If the type
1748 argument is omitted, "render" is used.
1750 RPN to CQL conv may use USE string attributes (bug #2978).
1752 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1754 --- 3.0.47 2009/07/08
1756 Function yaz_xml2query allows a diagnostic element in the PQF XML
1757 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1758 code and additional info respectively.
1760 The BER BOOLEAN is now the integral type Odr_bool which still happens
1761 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1762 typedef'd to Odr_int. This is still an integral 'int', but it may be
1763 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1764 ASN-1 compiler as well as programs has been updated to use the new types.
1766 --- 3.0.46 2009/06/08
1768 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1769 only the bibliographic record was rendered. For type=opac, an OPAC
1770 record is only returned if it is present.
1772 iconv: small fix for encoding of advancegreek.
1774 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1776 yaz-client: option auto_reconnect=on really reconnects.
1778 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1780 server: avoid null ptr ref for for yaz_poll errors.
1782 build: fix RPM build for RHEL 5.3.
1784 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1786 --- 3.0.45 2009/03/31
1788 Fixed bug #2709: TCP connect returns Invalid argument.
1790 Fixed compilation for mingw.
1792 Honor charset for raw records (ZOOM_record_get).
1794 Fixed use of errno for threaded mode that was seen on Solaris 10.
1796 Fixed argument passing with blanks in value for Windows Service.
1798 Disable YAZ' own log rotate by default (no 1 GB limit).
1799 The variable l_max_size which specifies the log file limit is set to 0
1800 (DISABLED): This is due to the fact that YAZ is most often deployed using
1801 logrotate. Also YAZ can not perform log rotate because of unsufficient
1802 permissions (setuid).
1804 --- 3.0.44 2009/02/17
1806 List supported encodings in man page for yaz-iconv.
1808 Fixed missing SSL libs for --libs output
1810 Re-established OID record syntax application-xml. Nobody should use it
1811 but we don't want to change soname because of this symbol being absent.
1813 --- 3.0.42 2009/02/02
1815 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1817 Added member named_result_sets for init handler struct for the GFS. This
1818 allows a server to disable named result sets.
1820 Removed OID record syntax application-xml.
1822 Added support for rule-based transliterator for ICU wrapper of YAZ.
1824 Fixed bug #1902: yaz-icu XML output.
1826 Make YAZ checks Emacs friendly.
1828 BITSTRING value shows value. Bug #2346.
1830 ISO2709 decoding: skip control characters from indicator data.
1832 Omit sort key by default in yaz-icu's output.
1834 Allow combined single char options (again) for YAZ' options function.
1836 Utility yaz-marcdump got option to display YAZ version (-V).
1838 Allow YAZ to use ICU 3.4.
1840 Added new ICU test case which illustrates removal of diacritics.
1842 --- 3.0.41 2008/12/29
1844 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1846 --- 3.0.40 2008/12/29
1848 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1851 Fixed bug #2352: yaz-marcdump crashes for certain record.
1853 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1855 Added support for Danmarc2 to UTF-8 conversion.
1857 Added support for ISO5426 to UTF-8 conversion.
1859 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1860 implementation version.
1862 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1864 --- 3.0.38 2008/11/10
1866 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1867 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1869 ZOOM C now interprets databaseName option for ZOOM connection as path
1872 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1874 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1876 Dummy Libxml2 types no longer defined in headers of YAZ'.
1878 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1881 --- 3.0.36 2008/09/26
1883 Various ODR chapter fixes.
1885 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1887 Added missing source for Windows compilation, mutex.c.
1889 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1891 For SRU connections in ZOOM all records up to "count" are now fetched.
1893 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1894 in Windows due to bad error handling for Libxml2.
1896 Added facility for sending arbitrary records (ASN.1 any) using
1897 ZOOM C's Extended service update. Patch by Sam Reynolds.
1899 New options for ZOOM C's connection, logapdu which makes ZOOM log
1902 --- 3.0.34 2008/06/18
1904 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1906 --- 3.0.32 2008/06/12
1908 Fixed memory violation that could occur when decoding UTF-8. This bug
1909 was only present in 3.0.30 of YAZ.
1911 --- 3.0.30 2008/06/06
1913 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1914 GNU TLS is used by default (if found).
1916 yaz-ztest returns OPAC records if a client asks for OPAC.
1918 Improved speed of MARC-8 encoding.
1920 Added support for lossy and loss-less MARC-8 encoding.
1922 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1924 Added new Windows Service wrapper (sc).
1926 yaz-client's itemorder command may now send a file.
1928 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1930 Added new function yaz_log_xml_errors.
1932 Allow (but warn) unknown XML attributes in MARCXML parsing.
1934 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1936 The UTF-8 to MARC-8 conversion now uses a different set of characters
1937 for Greek symbols. Bug #2120.
1939 --- 3.0.26 2008/02/21
1941 Added yaz_daemon (daemon.h).
1943 Fixed bug #2068: pkg-config trouble
1945 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1947 --- 3.0.24 2008/01/28
1949 Document --with-xml2 option.
1951 Added OPAC XML XSD (etc/opacxml.xsd).
1953 Allow glob mask for name attribute in retrieval element for the
1954 generic frontend server's retrieval facility.
1956 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1957 except POLLIN/POLLOUT.
1959 Fixed error handling in cs_listen. Bug #2037.
1961 --- 3.0.22 2008/01/20
1963 Fixed version in yaz/yaz-version.h.
1965 Fixed bug #2027: Crash when closing connection.
1967 Changed configure so that ICU support is only enabled if only ICU
1968 and Libxml2 is available (because the ICU chain is XML based).
1970 --- 3.0.20 2008/01/15
1972 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1973 is built. Only this DLL depends on the ICU runtime.
1975 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1976 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1978 Changed license of CCL module to 'Revised BSD'. After consultation with
1979 remaining members of the original EUROPAGATE consortium, we are re-issuing
1980 the CCL module without a separate license. The software was developed by
1981 Index Data as part of a research project. The special license was included
1982 to help feed usage information back to the project consortium to support
1983 project evaluation. At this time, the project consortium has long-since
1984 disbanded, and the majority of the original principals have retired. At the
1985 same time, we have significantly modified the software during the following
1986 years, to the point where very practically no original code remains. To
1987 simplify re-use of the software, we have contacted those members of the
1988 consortium who could be reached, and agreed to re-issue the module as a
1989 proper part of the YAZ package.
1991 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1993 CQL closer to being version 1.2 compliant. CQL also allows free-form
1994 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1997 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1998 bug could make Extended services handling crash in the ZOOM layer. This
1999 bug was only present in YAZ 3.0.18.
2001 --- 3.0.18 2007/12/19
2003 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
2006 yaz-marcdump reads and writes collection wrapped records.
2008 Handle OPAC for record conversion module.
2010 Fixes for ICU wrapper.
2012 Allow ICU libs to be controlled with --with-icu .
2014 --- 3.0.16 2007/11/12
2016 Added yaz_poll which is a wrapper for select/poll. When poll is available
2017 and non-buggy, it is used, by yaz_poll . This allows more than 1024
2018 sockets to be in use.
2020 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
2021 functionality through an XML based configuration (ICU chain). This system
2022 is useful for search facilities such as Pazpar2 and Zebra that needs to
2023 perform tokenization of indexed material. The ICU code in a separate
2024 library libyaz3_icu.a.
2026 Added HTTP tunnel facility for COMSTACK, bug #1752.
2027 This is a facility that allows a Web proxy, such as squid, to tunnel
2028 Z39.50 traffic. This facility is "transparent" to must applications
2029 using YAZ. It's enabled by using pseudo transport connect: followed by
2030 the proxy address, followed by command, then follwed by he regular
2031 "virtual" addresss. For example,
2032 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
2034 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
2036 --- 3.0.14 2007/09/21
2038 Fixed bad memory reference in ZOOM_record - cuased by member not being
2039 initialized. This was a problem only in YAZ 3.0.12.
2041 Fixed bug in conversion from MARC to XML: Non-XML characters in control
2042 fields were not removed.
2044 Changed the way C code is generated from codetables.xml. Made a MARC-8
2045 conversion trie for each characterSet section rather than codeTable.
2046 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2047 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2049 --- 3.0.12 2007/09/12
2051 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2052 from ZOOM_record_error).
2054 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2056 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2058 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2060 Better SRW-to-Bib-1 diagnostic mapping.
2062 ZOOM C and yaz-client announces SRU version 1.2 by default.
2064 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2067 Fixed in yaz_sru_decode to allow other version than 1.1.
2069 --- 3.0.10 2007/08/22
2071 Added support for SRU scan for ZOOM.
2073 Added support for the use of the older versions or Extended Service
2074 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2075 set to the version , 1=first, 2=second, 3=third. The third version is
2076 what ZOOM C has used so far. And that, obviously, is the default.
2078 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2079 therefore in Zebra and in SimpleServer-based applications). The new
2080 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2081 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2082 which is passed into the back-end search callback function.
2084 Added support for HTTP Basic authentication in clients: the SRU/W
2085 codec encodes the username/password elements of the PDU structure
2086 appropriately, and these may be set using the "user" and "password"
2087 options in ZOOM-C applications (the same options that are used for
2088 Z39.50 authentication).
2090 --- 3.0.8 2007/06/25
2092 Fixed bug #1208: SSL appears to be broken in ZOOM.
2094 Fixed bug #1206: Libxml2 include path weirdness.
2096 Added oid_name_to_dotstring.
2098 Allow elementSetName to be specified for ZOOM C record update.
2100 Allow waitAction to be specified for ZOOM C based for Extended Services.
2102 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2103 syntax OID. Bug introduced in YAZ 3 series.
2105 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2107 --- 3.0.6 2007/06/06
2109 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2110 directory. yaz-client now reads commands from file given by option -f
2111 if specified; then tries to read .yazclientrc in current directory.
2112 Failing that, it reads .yazclientrc from user's home directory.
2114 Added support for correlationInfo Note and ID for Record Update via
2117 Added yaz-client command querycharset which specifies character set for
2118 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2119 (termListAndStartPoint).
2121 Charset ISO5428:1984 is an alias for ISO5428-1984.
2123 Implemented a way to perform scan in a result set using Z39.50. This
2124 is achieved by attaching the result set name in the characterInfo
2125 (type InternationalString) of OtherInformation in the Scan Request PDU.
2126 The result set is identified in the otherinformation by the new OID:
2127 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2128 This allows for scan in result set and faceted search . Zebra did some
2129 of this in the APT term using attribute type 8 and value being result
2130 set. Using the OtherInformation approach for this is cleaner and easier
2131 to work with in proxies and the like. This facility can be used in
2132 yaz-client using new command setscan which takes a result set as first
2133 argument, start position (APT) as second.
2135 Changed decoding of SRU XML packed records to deal with servers that
2136 have recordData with XML data with multiple root nodes. Also make
2137 comparison for recordPacking case insensitive. Again, one server
2138 returns "XML" where others return "xml".
2140 For SRU responses allow Content-Type application/xml as well as text/xml.
2142 --- 3.0.4 2007/05/21
2144 Fixed bug in character set conversion of BER strings. Bug introduced
2147 --- 3.0.2 2007/05/08
2149 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2151 For OID class, use oid_class consistently.
2153 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2156 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2157 character set for bibliographic information interchange". By Giannis Kosmas.
2159 Added documentation on new OID API.
2161 --- 3.0.0 2007/05/02
2163 Changes to generic frontend server interface: added new member
2164 'query_charset' for bend_initrequest structure. A backend init handler
2165 should set this member to its native character set for query terms.
2166 When defined, the frontend server logic will announce this character set
2167 to a client if the negotiationModel bit is set by the client. All server
2168 implementors are encouraged to specify this. If a backend server does not
2169 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2171 Added CCL utility to remove terms (stop words) from resulting RPN
2172 tree. This is handled by functions with prefix ccl_stop_words_ .
2174 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2175 terms in RPN queries.
2177 Clean-up the CCL API. Moved some internal structures from ccl.h to
2178 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2179 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2180 This is replaced by ccl_parser_find_str which takes a string instead.
2182 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2183 libyaz.la is the core of YAZ except the generic frontend server and
2184 does not depend on POSIX threads anymore. libyaz_server.la is the
2185 generic frontend server facilities and uses POSIX thread functionality
2186 if available. The libyaz.la no longer depends on POSIX threads because
2187 the number of global structures is limited. NMEM no longer re-uses blocks
2188 between threads ; it simply free's memory immediately but allocates in
2189 "large" chunks as usual. We don't expect any performance penalties
2190 because of this. The yaz_log system is still using a global log_level so
2191 caution must be taken when modifying it with yaz_log_init_.. +
2192 yaz_log_mask_str. This, however, should not cause any trouble because
2193 these functions are called during initialization of application code
2194 anyway. `yaz-config --libs server` returns libs for server applications;
2195 `yaz-config --libs` returns libs for non-server applications.
2197 New OID database - with public definitions in oid_db.h. Removed old OID
2198 database including the head oid.h and definitions such as enum oid_value
2199 and struct oident. The new OID database uses the same string names as
2200 before but the 'protocol' is gone. There are now only two representations
2201 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2202 converts from string to OID; functions with prefix yaz_oid_to_string
2203 converts the other way.
2205 Change to emit_term() in CQL-to-PQF query translation: when a term has
2206 the /regexp relation modifier, do not process it for leading and
2207 trailing "^" and "*", which have quite different meanings in regular
2210 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2211 write handlers no longer carries a 'last' parameter. This will make
2212 yaz_iconv flush "less" characters. A flush is performed by call to
2213 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2215 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2216 removed, because function yaz_query_to_wrbuf does the same.
2218 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2219 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2221 Deprecated MARC utility functions removed.
2223 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2226 Branch split: YAZ_2_1_55_branch
2228 --- 2.1.54 2007/03/16
2230 Fix to ZOOM-C so that transparent reconnection is properly handled on
2231 connections that are in asynchronous mode.
2233 Fixed compilation on OpenBSD 4.0.
2235 Large strings in GRS-1 records are now properly displayed in yaz-client.
2237 Added character conversion support for "advancegreek"; based on patch from
2240 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2241 sequence is met. Before the error was not set so it would be unknown.
2243 Adjust yaz-marcdump MARC reader so that it skips until record separator
2246 --- 2.1.52 2007/03/07
2248 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2249 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2250 fd_set structure used as a bitmask for the FDs to be selected on.
2252 Using ACX_PTHREAD macro to check for POSIX threads.
2254 Fixed have-vsnprintf check.
2256 --- 2.1.50 2007/02/23
2258 Fixes for configure on BSD. Bug #900.
2260 Added snprintf/vsnprintf wrappers for systems that don't have
2261 limits (heavens forbid).
2263 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2264 created before all previous tasks were completed and removed from the
2265 task queue, the new task could be removed by a mistake.
2267 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2269 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2271 Fixed bug #832: Problem with MARC/charset in yaz-client.
2273 Fixed bug #668: save command line history for yaz-client.
2275 Fixed bug #830: pkg-config support.
2277 --- 2.1.48 2007/01/23
2279 Extended ZOOM result set options with two options that may be read by
2280 a client: resultSetStatus and presentStatus with values as specified for
2282 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2284 Fixed bug #827: Using SSL fails on Debian etch.
2286 Fixed bug #826: Weird looking chars for set of MARC records.
2288 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2289 that is treated as an ItemOrder with itemRequest being an XML document
2290 external. The value of "doc" is the content.
2292 Extended the GFS search facility. New member of bend_search_rr
2293 'estimated_hit_count' signals that hits is known to be an estmate
2294 (higher or lower than real hit count). New member 'partial_resultset'
2295 signals that the search was partial (hit count is lower or equal than
2296 real hit count). For Z39.50, the information is stored in resultSetStatus
2297 member of SearchResponse APDU. For SRU, the information is signalled
2298 via SRU diagnostic 59: "Result set created with valid partial results
2301 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2303 --- 2.1.46 2007/01/13
2305 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2307 Added ZOOM_connection_peek_event.
2309 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2310 the following new functions:
2311 ZOOM_event_nonblock, ZOOM_connection_process,
2312 ZOOM_connection_get_{socket,mask,timeout},
2313 ZOOM_connection_fire_event_{timeout,socket}.
2314 The existing blocking event handler, ZOOM_event, is a wrapper for the
2315 + blocking ZOOM_event_sys_{poll,select}.
2317 Implemented function ccl_xml_config which parses XML version of CCL
2318 configuration (bug #798).
2320 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2322 Added timings utility (yaz/timing.h)
2324 --- 2.1.44 2007/01/03
2326 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2329 Fixed bug #779: Rotation of apdu.log fails.
2331 Fixed for character set conversions:
2332 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2333 Honor G1 set in MARC-8 decoding.
2335 --- 2.1.42 2006/12/17
2337 Fixed bug #775: char conversion does not handle Alternative UTF-8
2340 Implemented function yaz_marc_read_line which parses MARC line format
2341 records. There is a wealth of formats out there. So far, this function
2342 reads line records produced by yaz_marc_write_line.
2344 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2345 more generic and easier to remember(!) options: -i format and -o format
2346 which specifies input format and output format respectively - where
2347 format is one of "marc", "marcxml", "line", "marcxchange".
2349 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2350 does not print anything except warnings for records.
2352 For yaz-marcdump, added support for MARC split into files (-s) with a given
2355 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2356 spec, at http://www.loc.gov/standards/sru/record-update/
2357 This has changed the binary layout of the following structs:
2358 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2359 bend_update_rr . Patch by Ko van der Sloot.
2361 Added GFS utility function bend_assoc_is_alive which returns 1 if
2362 association is still alive (client is connected); 0 otherwise (client
2363 closed connection). This allows busy servers to stop working for
2366 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2367 been a separate piece of software. This version of ziffy has been modified
2368 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2370 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2372 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2373 Client code may now interrogate options such as "init_opt_sort" to
2374 find out whether the server claims to support various options.
2376 --- 2.1.40 2006/11/27
2378 Added utilities yaz_{set,get}_esn to set/get element set name from
2381 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2382 of YAZ and has been so since YAZ 2.1.10.
2384 Implemented ZOOM_record_error which returns error information for
2385 record (surrogate diagnostic).
2387 --- 2.1.38 2006/10/31
2389 Updates for SRU Update by Ko van der Sloot:
2390 1. Changed name from "operation" to "action"
2391 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2392 versions in the code, marked as 'backward compatible'.
2393 3. Added diagnostics for SRU Update.
2395 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2397 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2399 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2401 For GFS, fixed problem with SRU diagnostic 'First record position out of
2402 range' being issued for 0 hits.
2404 zoomtst10 part of Windows Build.
2406 --- 2.1.36 2006/10/13
2408 Implemented yaz_filepath_comp which splits a path into file path
2409 components (required by Zebra 2.0.3+).
2411 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2412 BSD inspired license until now so this should not have any real impact on
2413 anybody. See http://www.opensource.org/licenses/bsd-license.php
2415 Fixed bug #687: Missing log lines.
2417 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2420 Fixed bug #689: SRU diagnostics to be added.
2422 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2423 whether a connection is idle (no more work do do).
2425 --- 2.1.34 2006/10/04
2427 Change type of optval from long to int for invocation of setsockopt with
2428 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2430 Added support for specifying the max log file size for the Generic
2431 Frontend Server. The size is given with option -r.
2433 --- 2.1.32 2006/09/21
2435 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2437 --- 2.1.30 2006/09/17
2439 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2442 Fixed bug in Generic Frontend Server that could cause a server to stop
2443 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2445 For the generic frontend server, the maximum record size is used as maximum
2446 size of incoming packages (SRU + Z39.50). The value until was previously
2447 only used in Z39.50 Init negotiation and, later, in a session controlled
2448 sizes of records returned. This is controlled using -k option. It can be
2449 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2451 --- 2.1.28 2006/09/04
2453 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2456 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2458 New option for yaz-marcdump -lpos=value which allows setting a portion
2459 of MARC header to a certain value.
2461 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2463 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2464 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2466 --- 2.1.26 2006/08/15
2468 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2471 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2473 --- 2.1.24 2006/08/08
2475 Fixed MARC ISO2709 encoding routines to deal with character set
2478 Minor changes to GFS logging. Database included in search request log
2481 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2482 cached/multiple records.
2484 Shared libraries are built by default on Unix+configure.
2486 Changed cql2pqf transformation to use a different evaluation order. The
2487 new order is: always, relation, structure, position, truncation, index
2488 and relationModifier. Old order was: always, relation, relationModifier,
2489 structure, index, position, truncation. Note that the the latter ones
2490 override former ones for identical attributes.. The new scheme means that
2491 it is possible to override any existing attribute with a relationModifier.
2492 And also that it is possible to override everything for the index rule
2493 (except the ones listed in relationModifier). No order is perfect but this
2494 one, we believe, covers more real cases.. The "always" should have been
2495 called "default", since the attributes there can be overridden with all
2498 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2499 compilation phase, but also for yaz-config --cflags output. This allows
2500 us to have public headers with Libxml2 stuff in them . It should also,
2501 eventually, make Libxml2 checks redundant in packages using YAZ, such
2504 --- 2.1.22 2006/06/15
2506 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2507 stored in uri, message and details.. Previously diagnostics were stored
2508 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2509 compatibility.. but he's probably the only one affected, so.
2511 Added support for CCL, compiled on the client side, in ZOOM-C. This
2512 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2513 input; the resulting query objects can be used for for searching with
2514 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2516 YAZ' configure searches for OpenSSL by default.
2518 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2519 SL_CTX_use_certificate_file. See
2520 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2521 for more info. Thanks to Ko van der Sloot.
2523 --- 2.1.20 2006/06/02
2525 Bug #600: SRU GET, POST support for yaz-client. Introduced
2526 command 'sru' which selects method SOAP/GET/POST.
2528 Allow missingValueAction to be specified for the sortspec string -
2529 function yaz_sort_spec. By default, the missing value action is null.
2530 Use ! to specify "abort". Use = followed by stringvalue to specify default
2533 Ensured that Present-handler (if defined) is called in GFS before any call to
2534 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2535 searchRetrieve requests.
2537 Documentation for YAZ is now based on the Docbook XML/XSLT using
2538 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2539 is no longer depending on jade/openjade or docbook-to-man scripts.
2540 PDF is no longer part of the distribution - but can optionally be
2541 made using DSSSL/jadetex or FOP.
2543 Added retrieval handling support in Generic Frontend Server to support
2544 conversion between MARC/XML as well as XSLTtransforms. See
2545 etc/yazgfs.xml for an example.
2547 Added Authentication support to Generic Frontend Server in SRU
2548 mode. Authentication using HTTP Basic is supported, as is the use
2549 of 'x-username' and 'x-password' parameters in the request itself.
2551 Added support for a new character set MARC8s identical to MARC8 except
2552 that it converts combined characters to single Unicode characters in the
2553 Latin-1 range (when possible).
2555 --- 2.1.18 2006/04/24
2557 ASN.1 compiler 0.4: generates brief Doxygen file header for
2558 generated .h/.c files.
2560 Utility yaz_iconv now supports conversion to MARC-8.
2562 New facilities for the MARC module. The reading - and writing of
2563 content are separate methods for the yaz_marc_t handle. The following
2564 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2565 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2566 format). Write functions have prefix yaz_marc_write_.. The existing
2567 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2568 available. Removed support for OAI-MARC and simplexml (not the
2569 simplexml from PHP5).
2571 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2572 to be returned for this connection.
2574 --- 2.1.16 2006/03/31
2576 Allow multiple languages and charsets to be specified with
2577 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2578 negcharset iso-8859-1,utf-8
2580 Translation of proximity nodes from CQL into PQF now works.
2582 Moved to automake 1.8, 1.9.
2584 Added function yaz_log_set_handler which allows a log handler to be
2585 installed. This handler will be called for all log messages. Output
2586 to file is also produced; but that can be disabled by passing NULL
2587 fname to yaz_log_init_file.
2589 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2591 For SRW (including GFS), accept application/soap+xml as content-type
2594 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2595 produces NO stylesheet reference even if a default stylesheet is specified
2598 --- 2.1.14 2006/03/14
2600 Updated Windows package to include yazd.dll + yazd.lib for the
2601 Development component.
2603 If the environment variable YAZ_LOG is set, then it is used as a
2604 string indicating the default level of logging to use if not
2605 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2606 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2607 used as before. So, for example, to omit warnings from YAZ logging,
2608 export YAZ_LOG=-warn
2610 cql_transform() now map structure and other attributes before indexes,
2611 so that index-specific structures and other attributes can override
2612 defaults. So now a combination of mapping specifications such as:
2614 index.dc.date = 1=date-modified 4=5
2615 does the right thing.
2617 cql_transform() now also respects the "always" mapping specification,
2618 which establishes an initial set of attributes to be used for all
2619 terms except where overridden by more specific attributes associated
2620 with the index, relation or modifier.
2622 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2623 which mode to use; one of "post", "get" or "soap" (SRW, default).
2625 Fixes for yaz_iconv routines: changed trie-based character set conversions
2626 to use only non-negative values for bit fields due to Sun's C compiler not
2627 supporting negative values.
2629 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2630 sequences where not read correctly. Fix by Rustam Usmanov.
2632 Updated win/makefile to use options, settings which makes things
2633 compile with VS C 2005.
2635 --- 2.1.12 2006/02/01
2637 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2639 In ZOOM socket code, use select instead of poll on MacOSX.
2641 ZOOM-C now support client-side compilation of CQL into RPN that is
2642 sent to the server, enabling CQL to be used against all Z39.50
2643 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2644 ZOOM_query object, and submit it using ZOOM_connection_search().
2645 The CQL-to-RPN translation uses a configuration file, the name of
2646 which must be specified in the Connection's "cqlfile" option.
2648 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2649 function, which takes as its start-term parameter a ZOOM_query object
2650 (which may have had either CQL or RPN set into it).
2653 --- 2.1.10 2005/11/29
2655 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2656 GFS to support this as well. Backend handler, bend_srw_update, does the
2657 update work. Code contributed by Ko van der Sloot.
2659 Allow retrieval of Search Result-1 information in ZOOM by the use of
2660 options that are attached to a result set. ZOOM documentation updated
2663 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2664 UTF-8 conversion. Patch by Raj Patel.
2666 Added option -m to GFS to control formatting of timestamps in log file.
2668 Added 'exit' as synonym for 'quit' in yaz-client
2670 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2671 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2672 for the new members. Patch by Ko van der Sloot.
2674 Added support for SRU POST. It is supported for content-type
2675 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2677 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2678 Instead make the library libyaz.la multi-threaded. Threading as a whole
2679 can still be disabled by configure option --disable-threads. Previosly,
2680 with older GLIBCs there were problems with MT libs under Apache. This
2681 has now been fixed a long time ago.
2683 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2686 CQL module modified to be case insensitive for relations/indexes/operations.
2688 Fixed bug in CQL transform code: incorrect value relationModifieder
2691 Added 'show all' command for yaz-client which retrieves all results
2694 Added new yaz-client, xmles, which takes a (private) OID and
2695 a document to be sent as an extended service request.
2697 Describe new yaz-client commands wait_response and set_auto_wait.
2699 Increase TCP/IP listener backlog from 3 (which I am guessing was
2700 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2701 that the socket will queue as many incoming connections as it's able
2702 to handle ongoing connections. In other words, it will never now
2703 refuse a connection that it would be able to handle merely because
2704 it's not got around to accepting() enough of the pending connections
2705 yet. This is the behaviour anyway under Linux, where the listen()
2706 argument is ignored; but not under BSD and on systems such as
2707 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2708 YAZ-based servers should now be uniform across operating systems in
2711 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2712 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2713 This allows yaz-marcdump to read large MARC batches (>2 GB).
2715 Modified all YAZ source files - except the source which is auto-generated
2716 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2719 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2720 corresponding to the existing *_setl() function. These allow option
2721 values containing arbitrary valuues.
2723 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2724 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2725 except that it returns an indicator of whether or not the sort
2726 criterion was accepted (0 for OK, -1 for invalid).
2728 --- 2.1.8 2005/06/07
2730 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2731 MARC output rather than returning "new" buffer.
2733 yaz-client warns about unknown init options.
2735 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2737 --- 2.1.6 2005/05/24
2739 Added support for SRW sort in Generic Frontend Server. Patch
2740 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2741 sortKeys - or NULL if none is provided.
2743 Fixed bug #307: It was impossible to specify indefinite/no timeout
2744 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2747 Added support for multiple languages and charsets to be specified in
2748 ZOOM. Each charset/language is separated by a blank. If negotiation is
2749 in effect in init-response, Option
2750 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2751 Code based on patch by Vasiliy Osadchuk.
2753 Fixed bug #306: infinite recursion that occurred when calling
2754 yaz_log_level_init as the first call (before other log level or
2757 Fixed bug in scan handling in front end server: if preferred-Position-In-
2758 Response was non-present, a NULL pointer referece was performed.
2760 --- 2.1.4 2005/04/26
2762 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2763 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2764 now defined for all those error codes. So instead of putting 109 in
2765 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2766 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2768 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2771 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2773 Program yaz-client now exits and produces an error message if multiple
2774 Z39.50 servers are specified on the command line (none or one allowed
2777 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2780 --- 2.1.2 2005/03/16
2782 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2784 Fixed bug #272: Preserve spacing for CCL terms.
2786 --- 2.1.0 2005/03/14
2788 Added support for virtual hosts and multiple backend servers for
2789 the YAZ frontend server. The configution is XML based and
2790 support specificition of CQL to RPN mappings and explain information.
2791 See section "Virtual Hosts" in the YAZ manual.
2793 Extended OPAC display utility. OPAC display utility renders
2794 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2795 to supplement yaz_marc_decode_wrbuf.
2797 Fixed a bug in MARC decoder that could caused it to crash for some
2798 invalid MARC records. More diagnostics and warnings where added in
2799 XML output (warnings, etc are stored in comments).
2801 --- 2.0.34 2005/02/08
2803 Fixes for UNIX domain sockets. Bug #261.
2805 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2807 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2808 Added yaz_marc_subfield_str which defines subfield lead string which is
2809 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2810 yaz_marc_endline_str which defines end of fields string used in
2811 YAZ_MARC_LINE format. Default string is newline.
2813 Experimental support for MarcXChange. This format can be produced
2814 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2815 http://www.bs.dk/standards/MarcXchange.xsd
2817 Added yaz-client commands scansize that sets maximum number of
2818 entries to be returned by scan.
2820 --- 2.0.32 2005/01/11
2822 Added support for SRW scan in yaz-client and Generic Frontend Server.
2824 * Added whereInList member to SRW Scan Term.
2826 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2828 Fixed NMEM system to return aligned blocks on the smallest boundaries
2829 that are suitably aligned for all possible types on the particular
2830 architecture YAZ is being built for.
2832 --- 2.0.30 2005/01/04
2834 Fixed numerious warnings that was issued with newer versions of GCC.
2836 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2837 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2840 Make YAZ Generic Frontend Server slightly faster.
2842 Enhance (and reduce) logging for Generic Frontend Server.
2844 Revert YAZ log system so that it flushes every write operation
2845 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2847 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2848 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2849 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2850 will effectively disable old definitions.
2852 --- 2.0.28 2004/11/09
2854 Added yaz_log_time_format which specifies log format using
2857 Added yaz_log_module_level which returns mask for a module. Value
2858 is non-zero mask a if module is enabled; zero if disabled.
2860 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2861 in include/yaz/cql.h.
2863 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2865 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2867 Fixed bug #172: RPM builds does not enable SSL.
2869 Doxyfile.in part of dist. Doxyfile generated by configure.
2871 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2872 are given and the corresponding component does not exist.
2874 Extend CCL documentation in YAZ reference. Describe r=r.
2876 --- 2.0.26 2004/10/01
2878 Fixed MARC->MARCXML conversion to properly deal with
2879 fields, subfields, indicators having non-ASCII characters.
2881 Fixed MARC->MARCXML conversion so that ASCII control characters
2882 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2885 Added YAZ GFS support for conversion from Z39.50 surrogate
2886 diagnostics to SRW surrogate diagnostics.
2888 Bug fix: YAZ GFS did not return schema in explainResponse.
2890 --- 2.0.25 2004/09/30
2892 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2893 now converts recordSchema to elementSetName as well as schema URI.
2895 Fixed bug in COMSTACK that prevented HTTP request packages from being
2898 --- 2.0.24 2004/09/29
2900 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2901 does not require white-space before and after the dash in a range, e.g.
2902 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2905 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2906 due to new GCC removing "redundant" code.
2908 Added yaz-client commands scanpos and scanstep that sets preferred
2909 position and step-size for scan.
2911 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2913 Added CCL utility ccl_qual_buf which parses one or more CCL
2914 spec lines in a buffer.
2916 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2917 of name and value - ignoring empty lines and comments.
2919 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2921 Added odr_get_element_path which returns current element path for an
2922 ODR handle. This utility is useful in error handling or user-defined
2925 Added ODR_PRINT utility odr_set_stream which is is a more generic
2926 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2927 to a write function and pointer to close function. The close function - if
2928 non-NULL - will be called during odr_destroy.
2930 Fixed bug in CCL parser where truncation char was not removed from
2931 right side when truncation=both was in effect.
2933 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2936 --- 2.0.23 2004/08/11
2938 Fix buffer overrun in CQL parser when dealing with proximity (%).
2940 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2941 to UTF-8/UCS conversion is now only based on codetables.xml.
2943 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2945 --- 2.0.22 2004/08/06
2947 Add support for more "commit changes" in ZOOM (uses Extended Services).
2949 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2952 Yet another small fix for configure of SSL.
2954 --- 2.0.21 2004/05/14
2956 Fix SSL libs for configure when --with-openssl=DIR is given.
2958 --- 2.0.20 2004/05/10
2960 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2962 SSL comstack now uses yaz.pem certificate file on server side
2963 by default. Certificate filename can be configured by calling
2964 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2966 Fix bug regarding multiple calls to ZOOM_connection_connect.
2968 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2970 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2971 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2973 ZOOM now allows inspection of X509 peer certificate for verification.
2974 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2976 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2977 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2978 as "modular" but it simplifies things.
2980 Added cs_get_peer_certificate to that returns peer X509 PEM.
2982 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2983 NULL if SSL is unavailable.
2985 Documentation about MARC decoding tools.
2987 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2989 --- 2.0.19 2004/03/30
2991 Rename CHANGELOG to NEWS to follow GNU style packing.
2993 Fix bug with missing initialization of member in init_diagnostics.
2994 This bug affects threaded version of GFS server.
2996 --- 2.0.18 2004/03/20
2998 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
3001 Ensure zlib.dll is packed with Windows install.
3003 --- 2.0.17 2004/03/17
3005 Fix encoding of xsd:string to use text instead of CDATA.
3007 Fix endless loop in CQL parser with unbalanced ".
3009 Use a more compact way to store MARC-8 conversion tables.
3011 --- 2.0.16 2004/03/16 Debian only
3013 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
3016 Update CQL parser to use new CQL 1.1 modifiers for booleans and
3021 --- 2.0.15 2004/03/01
3023 Another fix for decoding of XML packed records.
3025 --- 2.0.14 2004/02/25
3027 Fixes for Chunked encoding. White space not ignored after length spec.
3029 Update NS and use default NS for SRW diagnostic elements.
3031 --- 2.0.13 2004/02/23
3033 Implement ZOOM_resultset_cache_reset which resets record cache.
3035 Implement ZOOM_resultset_sort which sorts a result set.
3037 Implement chunked HTTP transfer.
3039 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
3041 --- 2.0.12 2004/02/16
3043 Added member 'schema' to bend_explain_rr structure so that backend
3044 can specify explain record identifier. Defaults to Zeerex 2.0.
3046 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3048 --- 2.0.11 2004/02/16
3050 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3053 Added init command for yaz-client which sends "extra" init request.
3055 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3056 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3058 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3060 Make ZOOM error code for "invalid query".
3062 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3064 --- 2.0.10 2004/02/05
3066 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3069 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3071 Added option -p <file> to make Generic Frontend Server to write PID file.
3073 Added option -D to put Generic Frontend Server in background on its own.
3075 Make ZOOM C recognize option "password". If unset, "pass" is used
3076 (for backwards compatibility).
3078 Fixed a bug in Generic Frontend Server that could make it crash if a
3079 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3082 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3083 Must be issued before open, in order to be in effect.
3085 --- 2.0.9-6 2004/01/12 Debian/Windows
3087 Make the SRU server more picky WRT unknown params, etc.
3089 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3091 New YAZ client command, options, that sets Z39.50 options.
3093 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3094 options from a string of tokens (one token for each option bit).
3096 Update SRW diagnostic code messages.
3098 --- 2.0.9-5 2004/01/07 Debian/Windows
3100 Handle user defined stylesheet for SRW/SRU.
3102 --- 2.0.9-4 2004/01/06 Debian/Windows
3104 Fix bug in decoding of Content-Length.
3106 --- 2.0.9-3 2004/01/06 Debian/Windows
3108 Fix a bug with decoding of XML packed records.
3110 --- 2.0.9-2 2004/01/05 Debian only
3112 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3114 Fix bug in SRW/SRU diagnostics decoding.
3116 --- 2.0.9 2004/01/05
3118 Fixed bug in Generic Frontend Server which could drop records exceeding
3119 preferred message size. Reported and fixed by Irina Dijour.
3121 Fixed calculation of package size for structured records in Generic
3122 Frontend Server. Reported and fixed by Irina Dijour.
3124 Fixed namespace for SRW/SRU diagnostics.
3126 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3128 --- 2.0.8 2003/12/22
3130 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3131 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3134 CQL changes to reflect recent changes to the specification:
3135 * Documentation talks about context sets instead of index sets.
3136 * Documentation talks about indexes instead of qualifiers.
3137 * The CQL-to-PQF transformer's configuration file now uses
3138 "index.set.name = <attributes>" instead of the old form
3139 "qualifier.set.name = <attributes>". (Both forms are still
3140 understood but the latter is deprecated.)
3141 * CQL terms with no explicit index specified are now interpreted as
3142 cql.serverChoice instead of srw.serverChoice (which of course
3143 behaves exactly the same.)
3145 --- 2.0.7 2003/12/16
3147 MARC conversion can now generate ISO2709 output in another
3148 character set. yaz-marcdump uses this facility if you invoke it
3151 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3152 functions from there can be used from C++.
3154 --- 2.0.6 2003/12/04
3156 Frontend server now transfers memory from decoded packages to stream
3159 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3160 references to show up.
3162 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3163 the ZOOM Abstract API. The older names for the same options are still
3164 also supported for the benefit of old applications.
3166 ZOOM-C supports "implementationId" and "implementationVersion" options
3167 to go along with "implementationName". These allow the user code to
3168 specify identification strings to be sent to servers.
3169 Add OID for the new ExtLite attribute set.
3171 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3172 as requested/supplid by Ere Maijala <ere@atp.fi>
3174 For generic frontend server, reverse the order of
3175 "toolkit-supplied / application-supplied" strings sent as implementationId,
3176 Name and Version. Also, remove the spaces around the slash. This brings
3177 the GFS in line with the behaviour of ZOOM-C on the client side.
3179 Add function ZOOM_scanset_display_term.
3181 yaz-client shows scan displayTerm if present.
3183 Utility yaz-iconv is now installed by default along with the man page
3186 Extend configure check for OpenSSL to use pkg-config where available (such
3189 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3190 server to specify uid/gid/mask for socket using the format
3191 unix:[user=uid,][group=gid,][umask=mask,]file=path
3192 If file= is omitted the existing format is assumed, e.g.
3194 in which case the mask is 0666 (rw for everybody).
3196 Major restructure of YAZ source. All source in libyaz is in src directory.
3197 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3198 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3200 Added man page for utility yaz-marcdump (used to be called marcdump).
3201 yaz-marcdump is installed by 'make install'.
3203 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3204 of incoming package failed.
3206 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3208 Change prototype of odr_perror: add const to message string.
3210 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3212 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3213 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3214 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3215 DNS lookup. There should not be any compatibility problems with this
3216 assuming that blocking=1 or 0 is used.
3218 Fix bad reference in UNIX comstack in function cs_addrstr.
3220 Fix for compilation on AIX.
3222 The generic front-end server (server/seshigh.c) now supports returning
3223 Init diagnostics to the client in User-information-field, in
3224 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3227 --- 2.0.4 2003/09/04
3229 Allow any CQL relation (not just all,any,exact,scr).
3231 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3232 that features the same UI.
3234 Implemented command update0 in YAZ client which is equivalent to
3235 update but uses old of Ext Update ASN.1.
3237 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3238 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3239 Previously no OID was used for this info.
3241 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3242 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3243 returns 'malformed search term' otherwise.
3245 SortResponse member resultCount now set to NULL in sort handler of
3248 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3251 Add three new utility functions for translating OIDs between various
3252 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3253 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3254 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3255 char *oid_to_dotstring(const int *oid, char *oidbuf);
3256 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3258 Reverted modifications for ES Update definition for z_IU0Update
3259 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3260 is back to YAZ 2.0.2.
3262 String value attributes for CCL parser.
3264 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3265 which their FirstSearch server returns in Init responses, sometimes
3266 carrying useful diagnostic information when Init fails. This has the
3267 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3268 "z39.50/oclcui.asn", where its definition is somewhat different from
3269 what OCLC document on their web-site, as required to interoperate with
3272 Support for anonymous authentication in yaz-client. Use the command
3275 * Fix the OID of the Index Data-local "admin" Extended Service from
3276 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3277 the 1000, which indicates a locally-defined OID, was a mistake.
3279 --- 2.0.3 2003/06/20
3281 Fix CCL directive @case handling so that it affects string match for
3282 both CCL keywords and qualifiers.
3284 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3285 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3286 Decoder has been updated with ASN.1 changes as listed in
3287 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3288 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3289 z_IUUpdate, remains unchanged.
3291 ZOOM_record_get may now return a record in a specific character set.
3292 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3293 "from" is the character set of record as returned by target. "to" is
3294 the character set to be returned. If omitted, "to" is UTF-8.
3296 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3298 New ODR utility, odr_getelement, which returns name of element for
3299 which encoding/decoding failed.
3301 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3302 in cases where a required element was omitted.
3304 Bug fix: some MARC8 sequences were not converted.
3306 New ZOOM option "step" which specifies number of records to be
3307 retrieved in one chunk. Used in conjunction with "start" and "count".
3309 SRW support for yaz-client. Use scheme http: to use it, e.g.
3312 yaz-client no longer does (un)intelligent character set conversions
3313 by default. Can be enabled with charset and marc_charset commands.
3315 xmalloc trace fix for 64-bit systems such as DEC alpha.
3317 Solaris 2.6 compile fix.
3319 New function, cql_strerror() translates SRW error codes, as returned
3320 by cql_transform_error(), into human-readable English strings. Used
3321 in yaz-client diagnostics when appropriate.
3323 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3324 converts it into a type-1 query which is sent to the server. This
3325 makes CQL available for use with all Z-servers, as opposed to the tiny
3326 minority that can handle CQL queries themselves.
3328 --- 2.0.2 2003/04/28
3330 New Debian package layout similar to the Redhat Package layout.
3332 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3333 and search result respectively.
3335 --- 2.0.1 2003/04/25
3337 Redhat package is now several packages: libyaz (runtime libraries),
3338 libyaz-devel (development and documentation, and yaz (utility programs).
3339 Package spec file by Morten Bogeskov.
3341 New member 'schema' in struct bend_fetch_rr which the name of requested
3342 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3343 handler MAY set this to reflect the schema of the returned record.
3345 New member 'display_term' in struct scan_entry. GFS now sets member entries
3346 and allocates scan entries to be filled by user scan handler. In previous
3347 version, entries member was allocated by the scan handler. That still works,
3348 but the GFS will ignore member display_term - assuming it was NOT set by
3349 the handler. The fact that the GFS now allocates the entries both allows
3350 for new members and makes a scan handler easier to write.
3352 Fix CQL lex buffer overflow.
3354 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3355 SRU default recordPacking is string.
3357 SRU protocol support for frontend server.
3359 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3361 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3363 Added scan for the ZOOM shell (zoomsh).
3367 * String Identifers for Schemas (Amendment 5).
3368 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3369 Old definition for schema
3370 Odr_oid *schema; /* OPT */
3375 Z_InternationalString *uri;
3376 #define Z_Schema_oid 1
3377 #define Z_Schema_uri 2
3380 * resultCount parameter to Sort Response (Amendment 1).
3381 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3383 Support for SRW 1.0 over HTTP. This is an optional feature and
3384 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3387 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3388 on the same port. SRW SearchRetrieveRequests are mapped
3389 to bend_init,bend_search,bend_fetch,bend_close.
3391 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3393 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3394 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3396 ZOOM connections are SRW based if schem http is used for hostname
3397 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3398 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3400 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3401 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3402 distance=n, order=true/false, relation=le, prox unit=word. If
3403 n is omitted, distance 1 is used.
3405 Fixed problem with C compiler include path in wrong order.
3407 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3408 on Solaris. Patch from Ko van der Sloot.
3410 New MARC decode API. All new functions operate on a yaz_marc_t
3411 handle. The most important new functions are: yaz_marc_create,
3412 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3413 decode and destroy respectively. Decoder can produce formats
3414 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3415 include/yaz/marcdisp.h.
3417 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3418 to UTF-8, UCS-32, wchar_t or Latin-1.
3420 * Prototypes for yaz_iconv_-functions moved to separate header
3421 include/yaz/yaz-iconv.h.
3423 Make a few private functions 'static' in unix.c. This prevents
3424 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3426 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3427 are set when Init Response is received.
3429 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3430 but returns diagnostic set as well.
3432 New function yaz_strerror which is a portable wrapper for
3433 strerror/strerror_r/GetLastMessage.
3435 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3436 is returned for MARC. If type is "oai", then OAI MARC is returned.
3438 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3441 --- 1.9.2 2002/11/26
3443 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3445 Fix bad race conditions on SIGTERM and terminate gracefully in
3448 Move retrieval (data1) module to Zebra since nobody seems to be
3451 Add GRS-1 render for ZOOM using same format as yaz-client.
3453 --- 1.9.1 2002/10/05
3455 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3457 Fix broken ESpec handling in data1 module.
3459 SGML reader parses comments and makes them part of the data1 tree.
3461 Added several type casts so that YAZ compiles as C++ code.
3463 ZOOM didn't handle PDU encoding failures properly.
3465 Added more Bib-1 diagnostics (approved extensions).
3467 GNU configure: better check for iconv.
3469 More portable use of accept, getpeername. Check for socklen_t. Use
3470 int/size_t if socklen_t is not defined.
3474 PQF parser rejects bad queries - including those with extra
3475 characters in them. PQF parser used to silently ignore that.
3476 Cleaner API for PQF added, which allows you to get detailed
3477 error information for bad queries (see yaz/pquery.h).
3479 Fixed bug in ZOOM_record_get for type "database".
3481 Implemented mini iconv library supporting conversions between
3482 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3484 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3486 --- 1.8.9 2002/08/20
3488 Fixed ZOOM C record cache so that preferredRecordSyntax and
3489 elementSetName is used to check for already fetched records.
3491 --- 1.8.8 2002/08/02
3493 Added three members in bend_initrequest structure to facilitate
3494 character set negotiation.
3496 Fixed a bug in frontend server that could cause indefinite
3497 loops under rare conditions.
3499 Revised character set utilities (charneg.h) so that encoding
3500 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3502 For PQF, directive @term <type> sets term type for Scan/Search.
3503 Here <type> is general, string, numeric, null. The term type
3504 is inherited - just like @attr.
3506 New call odr_set_charset that sets character set conversion for
3507 international-strings on a ODR stream. Prototype is:
3508 int odr_set_charset(ODR o, const char *to, const char *from);
3509 The InternationalString is still represented as C string in YAZ
3510 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3511 won't). On the protocol level, you can use any encoding.
3513 Support for UNIX sockets in ZOOM.
3515 Solaris recv sometimes returns errno == ENOENT. It is treated as
3516 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3518 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3519 both client and server. Code by Morten Bogeskov.
3521 --- 1.8.7 2002/05/22
3523 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3524 that they can be used directly from Visual Basic. You must recompile
3525 your windows APP if you're using ZOOM.
3527 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3528 Commands "lang" and "charset" sets language and character set respectively.
3529 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3530 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3532 Attributes from multiple CCL fields may be OR'ed rather than merged
3533 using directive "@field or". Fields are still merged by default -
3534 equivalent to "@field merge".
3536 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3539 Fixed bug in zget for parameter ExtendedServicesResponse.
3543 --- 1.8.6 2002/03/25
3545 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3547 Client displays USR.1:SearchResult-1 (hits per term).
3549 Additional Search Info for search in Generic Frontend Server.
3551 Fixed CCL parsing of "field=s".
3553 WIN32 installer - using the excellent NSIS software from nullsoft.
3555 Fixed CCL parsing of "field = - <number>".
3557 Added function yaz_marc_decode that decodes MARC for line mode
3558 display or XML (similar to that used by JZKit).
3560 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3561 Z39.50. But ISO/ILL was, however.
3563 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3564 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3566 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3567 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3569 --- 1.8.5 2002/02/03
3571 New YAZ client features: Command completion and new commands:
3572 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3573 Code provided by Jacob Poulsen.
3575 New call oid_trav, that visits all registered OIDs via callback.
3577 Function ZOOM_record_get now returns const char pointer rather than
3578 void pointer. It saves a lot of type casts.
3580 For YAZ client, command "auth" now allows you to set authentication
3581 in IdPass style. It is enabled when three tokens are given - order
3582 is user, group and password.
3584 Fix memory leaks in MARC record handling for ZOOM.
3586 New option for YAZ client, -k <kilobytes> that sets
3587 maximum record size. Similar to -k option for generic frontend
3588 server and yaz-ztest.
3590 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3592 Prefix query parser reports "fail" when bad attribute set is given.
3594 Fix in MARC decoder. Proximity logging. Fix for attribute set
3595 in scan handler for server. Patches by Shigeru Ishida.
3597 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3600 Configure option --with-openssl=<dir> now works when a directory is
3601 specified. Patch provided by Morten Bogeskov.
3603 New option for YAZ client, -u <auth>, that sets authentication.
3605 ZOOM fix: error information was sometimes "missing", since error
3606 was cleared/reset too when it shouldn't.
3608 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3610 --- 1.8.4 2002/01/04
3612 Scan for ZOOM API. New object ZOOM_scanset. New functions
3613 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3614 ZOOM_scanset_destroy.
3616 New ZOOM function, ZOOM_connection_last_event, that returns type
3617 of last event (such as "receive data", "send data", "apdu received",
3620 New ZOOM option, schema, that specifies schema for retrieval.
3622 New CCL feature. Qualifiers can be aliases for one or more
3623 other qualifiers (if more than one is given, OR is used).
3625 ZOOM uses named result sets if target supports it.
3627 Two new YAZ client commands: . (dot, which sources a script of YAZ
3628 client commands), and ! (to execute shell command.). Implemented
3631 Working on Debian packages.
3633 --- 1.8.3 2001/11/19
3635 YAZ client enables named result sets only if target supports it.
3637 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3639 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3640 with key="host" to get same result.
3642 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3643 Function Z3950_resultset_record(s) returns references to records
3644 "owned" by resultset. To become owner use Z3950_record_clone.
3646 Function z_ext_record handles Extended Services. Thanks to
3649 --- 1.8.2 2001/11/12
3651 CCL Parser fix: ignore token comma when dealing with and-lists.
3653 Documentation updates for COMSTACK.
3655 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3656 Changed prototype Z3950_records. For some functions, int parameters
3657 were changed to size_t.
3659 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3662 New MARC decode/display function, marc_display_exl, which properly rejects
3663 non-ISO2709 records. YAZ client uses it.
3665 --- 1.8.1 2001/10/29
3667 Fix bug: local attribute set wasn't set correctly in PQF strings.
3671 * Old Z39.50 codecs no longer supported.
3673 Added ZOOM C binding. See http://zoom.z3950.org/
3675 Renamed states for COMSTACKs to avoid confusion with events.
3677 Implemented cs_look and proper cs_rcvconnect.
3679 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3681 Configure detects POSIX threads on OpenBSD.
3683 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3684 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3686 When error is returned from present handler, non-surrogate diagnostic
3687 is returned in present response (and fetch handler is no longer called).
3689 * Minor adjustments to pquery parser (PQF). Token characters may be
3690 escaped by using backslash (C-style).
3692 PQF parser allows string attribute values to be specified. For @attr,
3693 non-numeric characters after the equal-sign are treated as strings
3694 (e.g. @attr 9=title).
3696 CCL trunction character may be defined (@truncation in file)
3698 * function zget_ExtendedServicesRequest sets waitAction to
3699 waitIfPossible (was wait).
3701 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3704 CCL operator names may be set in field definition files (CCL_bibset).
3705 See ccl/bib1 for an example.
3707 Fixes in ASN.1 compiler for C++ compatibility.
3709 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3710 and "op_or" to avoid conflict with C++.
3712 Fixed problem with GNU readline detection on Redhat 7.0.
3714 Added step-size for Scan backend handler.
3716 Fixed bug that made the frontend server crash when no attribute
3717 set was specified for scan.
3719 Front-end server automatically switches to original working directory
3720 when installed as an NT service. Previously -w had to be specified to
3723 Added extended attributes for retrieval module (data1), so that data1
3724 records carry d1_readXML/SGML attributes. d1_read also supports
3725 null-data rules ( <tag/>)
3727 On UNIX when POSIX threads are available, a separate library libyazthread
3728 is created. Programmers should link with that library and the yaz library
3729 when using threads. The reason for the split was that some applications
3730 on Linux, such as Apache, doesn't work well when using shared objects that
3733 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3734 (or any frontend server) in SSL mode by specifying ssl: followed by
3735 address. Only tested on UNIX.
3737 Added feature for CCL module. Virtual structure s=al or s=ol generates
3738 and-list and or-list respectively instead of phrase search.
3742 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3743 log_mask_str. This was done to avoid name conflicts with other libraries
3744 (such as other PHP extensions).
3746 Added raw OID member for preferred record syntax (request_format_raw)
3747 and returned record syntax (output_format_raw) for backend fetch method.
3749 Config file yaz-config now accepts options so that it returns specific
3750 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3752 Shared library support for UNIX using GNU libtool.
3754 * Modified backend interface. Request/Response struct's replaced by
3755 one read/write C struct. For example bend_fetchrequest and
3756 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3757 Every handler - even search has to be registered in bend_init
3758 handler. This means that the YAZ library no longer refers to
3759 external functions and it makes it possible to make the whole
3760 thing a single DLL/SO.
3762 Added Segment handler for backend server.
3764 Added Zmbol/Zebra administrative functions to YAZ client.
3766 Threaded frontend server on UNIX (when POSIX Threads are available).
3767 Starting the server with option -T enables multi-threading.
3771 Added configure option --enable-comp/disable-comp to control use
3772 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3773 located in sub directory asn.
3775 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3776 in ${exec_prefix}/bin along with the other programs yaz-client and
3779 GNU automake used to maintain makefiles.
3781 Added several OID's.
3783 Changed retrieval module so that we can load records with no abstract
3784 syntax defined. Tagpaths in these records are fully composed of string
3787 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3791 On UNIX, the generated makefile now supports a proper 'make install'.
3792 The prefix can be set via GNU configure to set the install location
3793 (default is /usr/local).
3795 * YAZ programs client and ztest were renamed to yaz-client and
3796 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3797 locations, such as /usr/bin,/usr/local/bin,etc.
3799 * YAZ Header files were moved from include to include/yaz. YAZ Header
3800 files are referred to as include <yaz/log.h> rather than <log.h>.
3801 The YAZ include path (-I ..) is therefore the same as before. Programmers
3802 should update their #include statements or use -Ipath/include/yaz
3803 instead. The main motivation for doing this change is that YAZ header files
3804 can be installed in "standard" locations /usr/include,/usr/local/include
3805 without introducing conflicts, since ALL YAZ header files are stored
3806 in subdirectory yaz (under /usr/include for example).
3808 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3809 rather than project/workspace files. We switched because project files
3810 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3813 Changed name of logging function, logf, to yaz_log, to prevent name
3814 clash with some math-log functions. The YAZ header log.h defines logf
3815 to yaz_log (#define) so there should be no incompatibilities by this
3818 Added bend_start/bend_stop handlers for server. These handler are
3819 called on start/stop of server. For windows they are called whenever
3820 a service is started/stopped.
3822 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3823 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3824 in util/yc.tcl. The auto-generated C code structures are, in a few
3825 cases, incompatible with the old decoders. There are differences in the
3826 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3827 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3828 The preprocessor variable ASN_COMPILED is defined when the compiled
3829 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3830 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3831 wish to use the old encoders/decoders you can specify --disable-yc
3834 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3835 version so that it supports both new - and old version of DB Update
3837 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3838 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3839 change. The name parameter can be set to 0 in which no name is specified
3840 for the construction. The macros odr_implicit and odr_explicit sets name
3841 parameter to zero for the construction involved. New macros
3842 odr_implicit_tag and odr_explicit_tag are similar to the others,
3843 except that a name parameter is added. For programmers' that don't use
3844 ODR they probably only need to change the call to z_APDU and z_External.
3846 Added access control facility by interfacing the TCP wrapper library.
3847 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3848 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3849 name of the daemon and enables the access control as specified in
3850 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3852 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3853 den Dool <H.M.vdnDool@kub.nl>.
3855 Added reference ID parameter to most functions in server API - refer
3856 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3858 Changed name of ccl library to libccl.a (was ccl.a).
3860 Fixed bug in decoder for Explain (Category TargetInfo).
3862 Added support for GNU readline in client. Thanks to Jacob Poulsen
3863 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3865 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3866 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3867 IMPLEMENTATION! This change was made to the development version before
3868 the ZIG decided to retract the amendment. If any users MUST be
3869 compatible with the original Update definition, PLEASE CONTACT US, and
3870 we will include a separate definition corresponding to the old Update
3871 ES. Note that because of the change to the ASN.1 of the
3872 TaskPackageRecordStructure we cannot define a single structure that
3873 will support both versions.
3875 * Added const modifier to buffer parameter for some ODR/BER encoding
3876 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3877 completeWAIS, odr_dumpBER.
3879 Fixed bug in client.c which caused a crash when a scanResponse didn't
3880 contain positionOfTerm.
3882 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3883 * will cause an error in a client if a non-YAZ target sends both a
3884 * list of Scan entries and non-surrogate diagnostics.
3886 Retrieval module enhancements. Tag sets may be typed in the reference
3887 to it. From the .abs-file the "tagset" directive takes a third optional
3888 integer type for the tag set referenced. From a .tag-file the "include"
3889 directive takes a third optional type as well. The old "type" directive
3890 in the tag set itself is still recognized but acts as the default type
3893 Backend interface change. Individual Scan terms returned from bend_scan
3894 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3895 in include/backend.h.
3897 Retrieval module enhancements. Multiple tag sets and attribute sets may
3898 be specified in abstract syntax specs. Revised the error/warning for
3899 logging messages reported by the retrieval module when reading the
3902 Object Identifier system (oid_..) changed. The API is backwards
3903 compatible but the oid-routines now allocates new OID's when needed.
3904 Raw OID's may be specified in oid_getvalbyname.
3906 YAZ now uses GNU configure to generate Makefile(s).
3908 * Minor changes in some of the member names of DeleteResultSetRequest and
3909 DeleteResultSetResponse. See include/proto.h.
3911 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3912 and added member 'languages' in TargetInfo (which was missing).
3914 Changed the way attribute sets are handled in the retrieval
3915 module. These are now cached, just like the abstract syntaxes
3918 Changed YAZ so that it links with compiled ASN.1.
3920 Added Explain-schema definitions and mapping routines. The following
3921 Explain categories have been implemented: AttributeDetails,
3922 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3924 Fixed minor bug in Windows version of Server Library.
3926 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3928 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3930 Added EXTERNAL: UNIverse Resource Report (non-standard).
3932 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3933 ENUMERATED and SET OF.
3935 * Added 'const' to some of the char pointer arguments for the
3936 functions, data1_read_node, data1_getelementbytagname,
3937 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3940 Fixed bug in data1_insert_taggeddata - the last_child member of
3941 parent wasn't initialised.
3943 * Changed data1_read_record and data1_read_node so that the supplied
3944 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3945 doesn't refer to any parts of the "SGML"-buffer.
3947 Fixed bug in server library (Windows version of statserv_remove).
3949 * Changed code so that it compiles as C++. The type definition
3950 of Odr_fun which is a member of Odr_arm was changed. The result is,
3951 that an explicit typecast is needed for the fun pointer when
3952 using Odr_arm - as in:
3953 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3955 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3957 Implemented the new structured date and time definition as approved
3958 by the ZIG. Added schemaId element to the specificTag in Espec-1
3959 (also approved at the last ZIG). Thanks to RVDM.
3961 Added some Object identifiers (RVDM).
3963 Changed the Update Extended Service (RVDM).
3965 Added command "refid" to client which specifies referenceId for
3966 the following requests.
3968 Implemented extended service handling for server. See ztest.c
3969 for an example as well as backend.h. New handlers are registerd
3970 in the Init handler.
3972 * Changed interface for sort in server.
3974 Added new members to statserv_options_block. It allows a server
3975 to read options from another source than just the command line. Thanks
3976 to Charles Woodfield.
3978 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3979 renamed to zboolean. Some C++ compilers complained about the name.
3981 Minor changes to gils.abs. Added index 's' (sort) on title
3982 and date/time-last-modified.
3984 --- 1.4pl2 1998/1/30
3986 Fixed bug in server library regarding inetd mode (-i). This bug
3987 was introduced by release 1.4.
3989 --- 1.4pl1 1998/1/29
3991 Added sort facility in client and backend server interface.
3993 Fixed problem with dependencies in Makefile(s).
3995 Fixed bugs for encoders/decoders of extended services and
3998 Implemented sub-tree feature for schemas. Sub-trees are
3999 referenced in *.abs-files. See explain.abs for an example
4000 of the use of this feature.
4002 Modified bib1.att; local attributes for ANY didn't include
4003 ANY itself (only affects use of the retrieval module).
4005 Fixed bug in plain SGML reader in function data1_read_node:
4006 tags with prefix "var" was incorrectly interpreted as variants.
4008 Added feature "sub-schemas" to enable references to - and definitions
4009 of - group of elements.
4011 * Removed member parent from type data1_element (in data1.h).
4013 Implemented function odr_nullval() that returns the value of
4016 * Removed member num_children from data1_node (in data1.h).
4018 Made NT service interface part of the server library. The
4019 function statserv_main uses the NT service when required and
4020 calls the statserv_start / statserv_close routines.
4022 Routine zget_SearchRequest and zget_PresentRequest fills
4023 resultSetName/Id member with "default" instead of "Default".
4025 Fixed memory leak in server. Request queue member wasn't freed.
4027 Fixed nmem_exit so that memory is freed.
4031 Revised the CCL parser utility to be thread safe.
4033 Added function, oid_ent_to_oid, to replace the function
4034 oid_getoidbyent, which is not thread safe.
4036 * Added nmem_init and nmem_exit to initialize and release
4037 NMEM resources. Function nmem_init should be called once in the
4038 initial thread before NMEM/ODR is used. statserv.c and client.c
4039 have been changed accordingly. The change was necessary to make
4040 NMEM thread safe. The NMEM memory pool is shared amongst threads
4041 in a process. Unix-based applications will still work fine without
4044 Added NT Services interface for the the Z39.50 (statserv) Server.
4045 Refer to the ztest.c source on the usage.
4047 Windows 95/NT port using MSVC5.0. Project files are included in the
4050 * Defined new 'global' handle for the retrieval (data1) system. The
4051 new handled, data1_handle, describes the state of the data1 system.
4052 This handle is passed as first argument to virtually all
4053 data1 related routines. The functions data1_create and data1_destroy
4054 creates and destroys a data1 handle respectively.
4056 Added ODR encode stream member to all backend request structures
4057 init, search, scan etc. This stream should be used to allocate all
4058 memory used for the response when thread safe operation is needed.
4060 Changed the comstack utility, cs_addstr, to be thread safe. The
4061 returned hostname string returned by the function is now part the
4064 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4065 function. The cs_straddr takes a COMSTACK handle as argument, so this
4066 function must be used after cs_create and before bind/connect.
4067 This function is thread safe.
4069 Moved test server to 'ztest' directory - generic server code still
4070 in 'server' directory.
4072 Made prefix query (pquery.c) utility thread safe.
4074 Added new function modifier YAZ_EXPORT to 'export' public DLL
4075 functions when using windows (see include/yconfig.h).
4077 Added definitions to the OID database (util/oid.c) (RVDM).
4079 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4081 Added call to ccl_rpn_delete in client program.
4083 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4084 release of RPN structure.
4086 Added support for C++, headers uses extern "C" for public definitions.
4087 With input from RVDM.
4089 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4090 Thanks to Ronald van der Meer (RVDM).
4092 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4094 Added support for private extensions to the OID database
4095 (oid_setprivateoids()). Thanks to RVDM.
4097 Added optional, physical ANY (key replication)
4099 Fixed null-reference problem in GRS-1 output filter.
4101 Proximity operator added to Prefix Query Format (PQF).
4103 In test client command "base" accepts multiple databases.
4105 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4109 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4111 Smallish bug-fixes in the new encoders/decoders (explain).
4113 Bug fixed in DeleteRequest.
4115 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4117 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4119 Added SOIF syntax (using private OID for now) to retrieval module and client.
4121 Added Update extended service.
4123 Added SearchResult-1 additional info structure.
4125 Added optional CCL (ISO8777) interpreter as separate module. Available
4128 --- 1.2 1996/6/10 (1st anniversary release)
4130 Added Summary record syntax. Lightly tested.
4132 Added OPAC record syntax. Untested.
4134 Added ResourceReport service encoders/decoders. Untested.
4136 Fixed bug in z_Unit - wrong tagging on unitSystem.
4138 Fixed bug in the DiagRecs decoder.
4140 Added options for max PDU size and session timeout to frontend-server.
4142 Added documentation of query-language parsers and other supporting utilities.
4144 [frontend-server] Added Attribute set to the bend_scanrequest API.
4146 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4147 surrogate diagnostics were generated.
4149 [retrieval] Allow multiple local values for attribute.
4151 [retrieval] Allow multiple attributes per element in .abs files. index type.
4153 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4155 --- 1.1pl2 1996/4/10
4157 Minor changes, mostly specific to Zebra's requirements (retrieval)
4161 Repaired bug in frontend server when running multiple listening
4162 endpoints in dynamic mode.
4164 z_External() now won't break if a known, ASN.1 value comes encapsulated
4165 in an octet-string. The value will pass through unmodified in an Odr_oct.
4167 Added a bit of code to the demo client to decode & display
4168 ASN.1-structured records represented in the octet-aligned branch of
4169 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4171 Added z_ext_getentbyref() to the ASN module. Doc updated.
4173 * Completed the SCAN definition in the ASN module. This may break SCAN
4174 code based on older YAZ-versions at compile-time. The fix is easy -
4177 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4178 under the SCAN definition. Remember to initialize this, server-people.
4180 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4181 that this does not extend to ODR and ASN.
4183 Comstack allows insertion of established socket (primarily for
4184 inetd-operation of servers). Doc updated.
4186 Front-end server can now start from the inetd in TCP mode. Doc
4189 --- 1.0pl4 1996/1/24
4193 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4194 the rank and record number.
4196 Adjustments to the frontend server.
4198 Fixed diagnostic BER dumper. It ignored the file argument.
4202 Various changes to retrieval module.
4204 Changed the union discriminators of the protocol files from enums to
4205 ints paired with #defines.
4207 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4210 *Changed operator in the RPN structure to 'roperator', again to avoid a
4213 Fixed problems in Explain decoders/encoders.
4215 --- 1.0pl2 1995/12/6
4217 Memory bug in log module fixed.
4219 --- 1.0pl1 1995/12/5
4221 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4223 Bug in Explain DatabaseInfo module fixed.
4225 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4229 The shift to v1.0 signals that we now consider the *core* functionality
4230 of YAZ reasonably stable (the core being more or less equivalent to
4231 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4232 tested (Explain not at all - though that will happen soonish).
4234 Minor changes to code to support Windows port.
4236 Various minor changes after we're getting to use GRS-1 & co. more.
4238 Added Espec-1 format.
4240 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4241 of the protocol and it cannot be selected when encoding (maps into 'string'
4242 when decoding). Needed to talk to some servers.
4244 Demo client can request simple element set names.
4246 Added Diagnostic Format encoders/decoders.
4248 Added simple Close handling to frontend server (no hooks for resource
4249 reporting yet), and demonstration client.
4251 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4253 --- 1.0b3 1995/08/24
4255 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4256 handled incorrectly when records were requested in the searchResponse. This
4257 will only affect you if you use the frontend-server.
4259 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4260 Test-client will ask for and print GRS1. Ztest will return dummy records
4263 Added Explain encoders/decoders to the service-level API. Untested.
4265 Added Extended Services: Item Order encoders and decoders to the Service-
4266 level API. Untested. We could use a recent copy of the pertinent bits
4267 of the ILL protocol to add those bits.
4269 Added diagnostic format 1 encoders/decoders to the service-level API.
4272 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4273 odr_cons.c, which causes a more correct output.
4275 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4276 was always set to 0 when no records were requested in the searchRequest.
4278 * Added better external-handling. This shouldn't harm old code that
4279 *encodes* externals. It can break code that looks for a
4280 'single-ASN1-type' representation, since those types that are known
4281 are now decoded immediately. Look at the SUTRS sample code in
4282 seshigh.c and client.c. Documentation updated.
4284 Handling of structured records in bend_fetchresponse. Length -1 marks
4285 structured record, type is deduced from format field.
4287 --- 1.0b2 1995/06/27
4288 Fairly quick maintenance release to add SUTRS support.
4290 Fixed handling of SUTRS records in the demonstration client.
4292 * Added format field to the bend_fetchrequest and bend_fetchresponce
4293 structures of the backend API (frontend server). When the record is
4294 returned, the value of the format field is mapped to an OID. The
4295 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4296 of the record. The special value VAL_NONE in the bend_request means
4297 that no specific format was requested by the client. Documentation
4298 updated accordingly. Test server (ztest) will return a fixed dummy
4299 SUTRS record if your client requests SUTRS.
