16 --- 5.14.11 2015/10/09
18 Fix RPN to CQL rejects local Bib-1 attribute set YAZ-861
20 ZOOM C: tweak when connection failed is returned
21 For cases with multiple socket addresses for some hostname, eg
22 localhost IPV4+IPV6, the code now properly returns "connection
23 failed" rather than "connection lost".
25 Various minor documenation tweaks from David Crossley. Thanks.
27 Fix windows uninstall does not remove start menu shortcuts YAZ-860

31 Prevent huge expansions in CCL s=sl YAZ-859
35 Fix segv in ZOOM_connection_fire_event_socket YAZ-858
36 The odr_in memory taken by handle_srw_response, and, thus if result
37 set is destructed before we expect the HTTP response (hres) it may
38 be come invalid. Therefore we inspect hres before the call to
41 Fix possible deadlock in backtrace (2nd attempt) YAZ-856
42 An alarm is set up so that backtrace is terminated if it hangs.
43 Even if backtrace the handler also attempts to spawn gdb.
47 Fix SEGV for s=sl for 3 terms and syntax error YAZ-857
51 Fix possible deadlock in backtrace YAZ-856

79 Fix rpn2cql: structure, relation problem for serverChoice YAZ-849
80 Problem was that for things mapped to cql.serverChoice the relation
81 would sometimes be omitted when it should not. Eg for relation "all".
85 Document zoom extraArgs YAZ-817
87 Fix ZOOM: crash extended services diagnostics YAZ-846
88 The immediate fix is to prevent ZOOM_set_dset_error from removing
89 current task from connection. This, however, has been assumed in a
90 number of places so this fix is rather large unfortunately.
94 Make yaz_log_reopen async-signal YAZ-845
95 Fixes potential dead-lock issue with YAZ_DAEMON_LOG_REOPEN flags for
100 CCL: new feature s=spl (split-list) that splits terms in a search into
101 sub-phrases of all sizes (from 1 up to the number of terms) with order
102 preserved. For 3 terms the CCL search
105 @or @or @or @and @and a b c @and "a b" c @and a "b c" "a b c"

137 --- 5.11.0 2015/03/31
139 Extend get_org_info (snippets) to return original string YAZ-836
140 Two new functions have appeared: icu_chain_get_org_info2 and
141 icu_iter_get_org_info2 with a 4th parameter being a pointer
142 to the original string.
144 Fix tcpip.c compilation failure on VC9 YAZ-835
146 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
147 The icu_iter_get_org_info returns information based on string
148 as it appears on tokenize step.

162 --- 5.10.1 2015/03/03
164 Fix test_sru.sh fails in pazpar2 YAZ-826
165 Unfortunately a regression occurred with YAZ 5.10.0 that would make
166 Pazpar2 fail for HTTP connections.
168 --- 5.10.0 2015/03/03
170 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
171 Introduce cs_create_host2 which returns if connection should be
172 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
173 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
175 Fix http proxy fails with yaz-client YAZ-824
179 Fix 0 ptr reference for OPAC records from XML YAZ-822
183 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819

189 retrieval: pick matched element-set rule YAZ-813
191 Fix crash in record conv rule 'select' YAZ-812
195 record_conv: selection by X-Path YAZ-811
196 That's a new step in record conversion system (<select path=".."/>)
198 Document record render parameters for ZOOM - including base64
202 Fix application/x-www-form-urlencoded + empty YAZ-810
203 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
204 and empty content was supplied.
206 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
208 Fail hard if Bison is not found and is needed YAZ-808
212 Enable YAZ backtrace for programs YAZ-802
214 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
215 Libxml2 2.9.2, Libxslt 1.1.28.
217 Fix daemon: parent process stops before child YAZ-806
218 Try to fix the situation where parent process stops before
219 child has acknowledged it .. SIGUSR2 back!
221 daemon: log message when keepalive stops.
225 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
226 would make yaz-marcdump crash when from-character set was issued.
230 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
231 New function yaz_enable_panic_backtrace which enables backtrace
232 handler for current process. The handler will call backtrace always,
233 then gdb to provide as much detail as possible.
237 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
238 and ZOOM record render will inspect leader 9 and switch to UTF-8
239 (Unicode) if that holds 'a'. This changes behavior, but is considered
240 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
242 Fix cs_put may reconnect if send fails. YAZ-798
246 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
250 Extended comstack with outgoing IP YAZ-795.
251 For cs_create_host + cs_create_host_proxy the vhost may be followed
252 by a outgoing host/IP. Separator is blank.
256 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
257 linker error with yazpp on Windows.
261 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
263 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792

273 daemon: properly report when receiving SIGUSR2 from child YAZ-785
277 xmalloc: throw assert for clearly invalid calls to malloc and
278 improve diagnostics YAZ-783 YAZ-784
282 Stop building debs for Ubuntu raring, quantal, oneiric.
284 CCL YAZ-781: for multiple use attributes in a specification the
285 generated RPN will perform @or on each term.
286 For spec: term u=31 u=1016
287 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
289 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
291 CCL YAZ-779: combo qualifier should allow for forward references
293 Fix buildconf.sh, automake too old on centos5 YAZ-778
294 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
295 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
296 accepts it without a warning.
300 GFS: client_query_charset conversion YAZ-777
301 This is a feature for Z39.50 clients that sends queries that are not
302 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
303 encoding given to UTF-8.
305 Echoed SRU arguments support YAZ-776
306 This is achieved with new function yaz_srw_get_pdu_e.
308 ZOOM: expire times set for redis/memcached YAZ-772
309 For both redis and memcached option --expire=seconds sets expire
310 time for a result-set/search. Default time is 600 seconds (10 minutes).
314 No [rest of output is omitted] limit for yaz_log YAZ-774
316 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
318 For ICU testing, pass -o to yaz-icu. This will test the
319 icu_iter_get_org_info function.
321 Fix null ptr reference for freeReplyObject YAZ-773
325 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
327 RPM: do not build with libmemcached support. The libmemcached library
328 on CentOS 5/6 does not work reliably for us (redis to the rescue).
330 configure: only allow libmemcached version 0.40 or later. That's the version
331 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
332 that's not an option, consider redis.
336 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
338 Fix zoom+memcached: present request out of range YAZ-767
342 CCL: add new qualifier r=omiteq which will omit relation=equals
343 for ordered relations. This should be used in combination with either
346 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
348 Solr: simplify yaz_solr_decode_response
350 Solr: use different local var for string manipulation
352 Solr: Get rid of hardcoded limit of extra_args
354 Solr: encode lucene query type YAZ-736
355 Make sure the queries are treated as traditional "lucene", because that's
358 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
362 Build packages for Ubuntu Trusty Tahr 14.04 LTS
364 wrbuf_cstr: fix off by one error.
366 wrbuf_buf: make it always return non-NULL
367 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
371 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
373 zoomsh: offer option -a apdulog
374 As we're used to from yaz-client and GFS based servers.
376 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
377 existing setting apdulog takes effect.
379 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
384 Add re-entrant CQL/Solr/RPN query conversion functions.
385 The re-entrant functions are: cql_transform_r,
386 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
387 These have same functionality as cql_transform,
388 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
389 return the additional infomration as WRBUF to make them re-entrant.
391 Remove CQL to Solr conversion and base solr_transform_t on
392 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
393 data structure as cql_transform_t.
395 cql2pqf utility allows RPN to Solr conversion
397 Fix assert in ZOOM when http connect fails YAZ-757
399 --- 5.0.22 2014/04/09
401 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
403 wrbuf_cstr: make it thread safe YAZ-753
405 yaz_log_init_file may take fd=<no> to open log file at the FD given.
407 --- 5.0.21 2014/03/21
409 Offer new utility function zget_AttributeList_use_string.
411 New conversion step, solrmarc, for record conversion module.
413 --- 5.0.20 2014/03/13
415 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
416 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
419 --- 5.0.19 2014/03/10
421 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
422 The standalone ZOOM sort was completely broken since 5.0.13.
424 ZOOM: generate event Connect rather than None for partial connect
425 (in fact getaddrinfo resolving).
427 ZOOM: only supply clientIP for InitRequest. Rather than for all
430 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
432 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
433 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
434 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
436 New "Facets" section in the documentation.
438 --- 5.0.18 2014/02/27
440 Call exsltRegisterAll in yaz_init_globals, so that all applications
441 using YAZ will have EXSLT things enabled.
443 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
445 Update various URLs to the re-organized SRU pages at LoC.
447 --- 5.0.17 2014/02/26
449 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
450 introduced in 5.0.12.
452 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
453 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
454 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
457 --- 5.0.16 2014/02/25
459 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
461 --- 5.0.15 2014/02/24
463 Fix gcrypt not properly initialized YAZ-740.
465 --- 5.0.14 2014/02/19
467 Describe memcached option for ZOOM.
469 ZOOM: throw present request out of range again YAZ-739
470 Was removed in YAZ 5.0.13.
472 --- 5.0.13 2014/02/18
474 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
475 with localtime_r when threads + fork is used (such as Metaproxy).
477 yaz-config: quote some RHS values (that might include blanks)
479 zoomsh: shows SearchResult-1
481 zoomsh: sortby command
483 zoomsh: use proper list of connections and result sets YAZ-725
485 Avoid yaz_log in sigterm handler for GFS YAZ-737
486 Logging is still performed, but outside sig handler.
488 New ZOOM C feature: result-set caching with memcached. Example:
489 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
491 Remove SSL via OpenSSL support YAZ-732
492 Also deprecate two functions from comstack that aren't working with
493 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
495 Revert "Bison: use %name-prefix directive rather than -p option"
497 --- 5.0.12 2014/01/22
499 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
501 SRU GET/Solr base URLs may hold additional ?args YAZ-729
502 ZOOM option extraArgs already does this, though. It seems useful
503 when dealing with Solr targets to limit by filter, eg.
504 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
506 Remove #fragment for HTTP request encoding YAZ-730
508 Doc: Update list of DLLs/LIBs
510 Doc: update href link to Unix utils and Git.
512 --- 5.0.11 2014/01/15
514 ZOOM: fix "lost connection" problem with servers that uses both squid
515 and another proxy behind it that returns Location headers with relative
518 zoomsh: do not use readline for stdin (no tty) YAZ-724
519 Just use fgets in that case. If the user hits Ctrl-D a new-line
522 zoomsh: empty command ignored YAZ-723
523 rather than performing exit of zoomsh.
525 yaz-url utility offers option -v to enable verbose mode.
527 yaz_url uses yaz_check_location and offers verbose mode.
529 Add new function yaz_check_location.
530 This function gets an absolute URI from Location (HTTP redirect).
532 cookie API: introduce yaz_cookies_reset
534 Update cql.y for newer bison YAZ-720
535 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
536 longer supported. Instead one must use %lex-param and %parse-param .
538 --- 5.0.10 2014/01/09
540 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
543 rpn2solr: support truncation left(2), left&right(3) YAZ-718
545 Mention SRU version 2.0 in yaz-client man page.
549 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
554 Make cs_parse_host public.A
556 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
557 introduced in YAZ 5.0.6.
561 Fix buffer corruption for yaz-ztest record fetch.
565 Allow yaz-ztest to return user-defined records (one record per file).
566 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
568 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
569 Use the stream write instead of odr_printf which has a 4K tmp buffer.
571 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
575 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
576 can read and write this format. For record format JSON, yaz-ztest returns
577 MARC-in-JSON records.
579 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
580 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
584 Improve error reporting for ICU chains YAZ-707
585 Report config element+rule when ICU status is "failure".
587 ZOOM: stop fetching if present response has no records YAZ-710
588 Some targets return less records than their hit count would suggest.
589 This prevents ZOOM from continuing to fetch records if any present
590 response has 0 records in the response.
592 Ensure that GFS calls exit if any listener fails YAZ-710
593 Before, if XML config was in use, it would start the default
598 yaz-ztest: -V shows version (like yaz-client -V)
600 New iconv encoding: danmarc YAZ-692
602 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
604 daemon: only wait for immediate child rather than all children. YAZ-704
606 yaz-client: fix setting of SRU record schema. If scheme was unset, it
607 could lead to invalid memory reference.
611 yaz-ztest returns schema for MARCXML test records. SRU require that
612 recordSchema for records.
614 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
615 instead of non-surrogate diagnostic. This is a per-record failure.
617 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
618 may refer to multiple listeners now. Attribute listenref is a comma separated
621 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
622 option is given for GFS, the dirname of filename (for -f) is used
623 as prefix for options such as cql2rpn, ccl2rpn, etc.
625 Content-Type charset fixes YAZ-701 . Do not inspect charset in
626 Content-Type header for SOAP when decoding SRU. The payload (XML)
627 itself tells what encoding it is. In response, never supply encoding
628 in Content-Type. The response payload (XML) tells what it is (with no
629 encoding in XML it's UTF-8).
631 HTTP decoding: allow blanks in URL paths YAZ-700
635 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
636 and facets. Ensure recordData and recordSchema are always present in
637 record element, because they are required.
639 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
642 Simplify in a lot of places using odr_strdupn.
644 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
648 Increase various buffers in GFS's statserv_options_block
649 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
650 This change makes many type-casts redundant, and, thus simplifies code.
652 Remove last bits of WAIS support.
654 Remove member 'size' from Odr_oct.
656 Slim down the public part of 'struct odr'. Most elements are not part
657 of struct Odr_private.
659 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
660 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
661 In particular facets are supported in both client - and server side.
662 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
663 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
664 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
665 both request/response). This is what a search handler in the GFS
666 will see (regardless of whether operating in SRU mode or Z39.50).
668 Changes to the srw.h (SRU/Solr) definitions include:
669 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
670 (char*), which replace union query and query_type (int). This is because
671 SRU 2.0 supports a queryType parameter. This also means that, to carry
672 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
673 x-pquery=PQFstring (extention parameter). The extension parameter
675 - New element, packing, that has information about SRU
676 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
678 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
680 New element, packing, in Z_SRW_explainRequest.
682 New elements in Z_SRW_scanRequest, queryType and scanClause.
683 These replace query_type and scanClase untion. This is similar to what
686 --- 4.2.69 2013/10/01
688 GFS: log when closing down - at least SIGTERM YAZ-684
689 Also change formatting WRT PID logging a bit.
691 Improve display of MARC records with multi-byte subfield IDs YAZ-695
692 In some rare cases subfield identifiers are multi-byte characters.
693 This will try to deterime length of those and split accordingly.
694 This affects display in line mode as MARCXML/MarcXchange. The encoding
695 of ISO2709 is the same.
697 Change inp argument to const for yaz_read_UTF8_char.
699 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
701 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
703 Better check of marc leader info YAZ-691
704 Problem is that some systems generate MARCXML/MarcXchange with
705 funny headers. These will not work if encoded as ISO2709.
706 Some tests produce new output, due to updated warning messages
708 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
710 yaz-client: display MAB records YAZ-689.
711 Thanks for Heiko Jansen for this patch.
713 New utility z_get_HTTP_Response_server which allows both HTTP server name
714 and HTTP server URL to be given in response.
716 Debian: do not depend on obs tcl8.3.
718 Debian: do not depend on obs libicu36-dev.
720 --- 4.2.68 2013/09/23
722 GFS: pass additionalSearchInfo to search memeber search_input if
723 given. Otherwise pass otherInfo. Request for facets and other search
724 related things will be passed there in future versions of YAZ.
726 New ZOOM setting, authenticationMode, which allows authentication
727 paramters to be encoded in the URL rather than via HTTP Basic auth.
730 rpn2solr: fix nested AND/OR handling. YAZ-685
732 Add comparison routines for some Z-types, such as NamePlusRecord,
733 RPNQuery, Query, RecordComposition and OtherInformation.
735 --- 4.2.67 2013/09/19
737 Don't decode MAB as MARC. Just like we don't attempt to decode
738 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
740 CCL: allow quoted terms for date ranges. YAZ-681
742 Introduce ccl_parser_qual_search. This function makes old function
743 ccl_qual_search, from YAZ 2, available again.
745 Add yaz_facet_list_to_wrbuf. YAZ-683
747 --- 4.2.66 2013/09/11
749 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
750 schema was given for search. YAZ-675
752 Add Solr date range searches. YAZ-621
754 --- 4.2.65 2013/08/22
756 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
758 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
760 ISO2709/MARC parse most octet aligned records; not just those that
761 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
762 MARC parse more records instead of just dumping as is. YAZ-670
764 ZOOM: proper caching for variations of record schema. YAZ-671
766 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
768 --- 4.2.63 2013/07/17
772 --- 4.2.62 2013/07/11
774 New utility z_get_HTTP_Response_details - an extended version of
777 New utility yaz_url_get_error which returns error message of last
778 failed yaz_url_exec call.
780 yaz-url and url functions: allow max HTTP redirects to be controlled.
782 New functions yaz_file_glob2, yaz_xml_include_glob.
783 These functions takes a flags parameter, which, for now only controls
784 whether to fail inclusion of a non-existing file (without glob
785 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
787 --- 4.2.61 2013/06/20
789 For MARC XML parsing, allow record without leader. A fake/default leader
790 is inserted and a warning is tagged with the record.
792 ICU: fix leak in in icu_iter_get_org_info.
794 --- 4.2.60 2013/06/14
796 ICU: fix bug in icu_iter_get_org_info (un-init variable).
798 --- 4.2.59 2013/06/11
800 Implement z_HTTP_header_remove.
802 --- 4.2.58 2013/06/11
804 ICU: Disallow 0 ptrs for some ICU string utilities.
806 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
807 returns original tokens (before normalization).
809 CCL: avoid z39.58/regex truncation when not needed. Apply only the
810 conversion of those masks, when absolutely necessary.
812 CCL: configurable masking character - @mask. Default masking character
815 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
816 full response anyway, so a Transfer-Encoding header will obstruct the
819 --- 4.2.57 2013/05/15
821 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
822 picking a socket. Problem is that some systems has IPV6 support, but
823 we can't create sockets for them, so we pick AF_UNSPEC first.
825 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
826 use content_len to determine resulting Content-Length in HTTP response
827 and NOT Content-Length supplied in headers by user.
829 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
830 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
832 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
835 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
836 with big endian and unsigned char (by default).
838 --- 4.2.56 2013/04/26
840 Fix yaz-client connect (crash in 4.2.55).
842 --- 4.2.55 2013/04/26
844 Fix proxy/host problem for ZOOM that could occur if unix sockets
847 New Debian package libyaz4-dbg.
849 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
850 differently in tcpip_close.
852 --- 4.2.54 2013/04/17
854 Windows installer of YAZ includes YAZ4J as a component.
856 CQL: allow "extra terms" again, by default. Thus, the CQL parser
857 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
858 and earlier. CQL parser may operate in strict mode where queries
859 not conforming to the standard BNF are rejected (syntax error).
860 Whether the CQL parser operates in strict mode is controlled with
861 cql_parser_strict . Strict mode enabled with option -S for utilities
862 cql2pqf and cql2xcql .
864 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
866 --- 4.2.53 2013/04/10
868 New charset, MARC-8c, which is like MARC-8 but allows control characters
869 0x01 through 0x1F, except ESC to be passed through verbatim.
871 Fix a problem with duplicate sub field character in MARC output. Problem
872 happened only when output was MARC-8 encoded.
874 --- 4.2.52 2013/04/03
876 yaz-ztest: Use hash for fake hit count. Before, random number was used.
877 This is problematic for unit tests using yaz-ztest. This patch also makes
878 a hash for CQL queries. For RPN, any term with a leading digit will be
879 treated as pseudu hit count (to force any particular hit count by a client).
881 yaz-ztest: return unique MARC dummy records. Beyond record offset
882 24, the author surname is patched with offset to make all records
885 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
886 on system wide default (/proc/sys/net/ipv6/bindv6only).
887 @4 binds to IPV4 only. @6 binds to IPV6 only.
889 Update CQL API documentation a bit
891 CQL: don't accept extra terms for queries. Makes the CQL parser
892 stricly conformant to the standard.
894 --- 4.2.51 2013/02/12
896 GFS: scan handler gets extra_args from request and may return extra
897 response data . That's for SRU only.
899 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
901 --- 4.2.50 2013/01/30
903 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
905 OPACXML: sync spelling of availabilityDate in XML to that of Schema
906 opaxxml.xsd. The schema had the correct spelling of this member always.
907 The ASN.1 was mis-spelled and still is (API change) - we are
908 not changing this. However, the OPAC to XML conversion had yet
911 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
914 New function, z_ext_record_oid_nmem, which is similar to
915 z_ext_record_oid but takes NMEM rather than ODR
917 --- 4.2.49 2013/01/18
919 ICU: New conversion element 'join' which joins tokens into one
920 with a custom character given by rule attribute.
922 --- 4.2.48 2013/01/10
924 New GFS search member: present_number. This is a hint to the
925 search handler how many records are going to be fetched immediately
926 following search. There's no guarantee that it's going to be the case,
927 since it depends on hit count (for Z39.50 piggyback) and whether errors
930 Make a few functions static (private). The functions getbyte_stream,
931 ungetbyte_stream and yaz_gets are now private. They were never declared
934 yaz-marcdump: exit(5) for serious decoding errors
936 ISO2709 decoding: be more picky WRT header
938 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
939 was only used as to indicate that next-result-set-position should be
941 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
942 Based on patch from Ashley Sanders.
944 Make some functions static/private in PQF parsing. Those functions were
945 never declared in a public header and so should not be in use by
946 applications based on YAZ.
948 --- 4.2.47 2012/11/23
950 ZOOM: special options to control APDU logging.
951 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
952 logging of APDUs until "saveAPDU" option is set again. If logging is
953 already enabled the effect is that current APDU buffer is cleared.
954 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
955 logging (default behavior on new connection).
956 The APDUs sent/received can be obtained by using
957 Using ZOOM_connection_option_get(c, "APDU") or
958 ZOOM_connection_option_getl(c, "APDU", &l).
960 GFS: relay implementation_version from backend
961 From 3.0.40 and later, implementation_version from backend was
962 not used in init response at all.
964 --- 4.2.46 2012/11/15
966 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
967 mode at all. Probably never did.
969 Make a new version of ztest.pem that, at least, is not expired.
971 --- 4.2.45 2012/11/13
973 Fix description of CCL directive 'case'.
975 More tight checking of form arguments (yaz_uri_to_array). Makes
976 YAZ better at rejecting big and/or bad POSTs.
978 SRU decoding does not report more than up to 10 invalid arguments.
980 rpn2cql: less quotes in generated terms. Semantics unchanged, but
981 it's prettier this way.
983 --- 4.2.44 2012/10/25
985 New utility yaz_decode_init_diag. Defined in proto.h.
987 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
988 given for unix local socket.
989 The COMSTACK string for doing so is:
992 unix:/myfile:tcp:localhost:9999/mybase
993 unix:/myfile:localhost:9999/mybase
994 unix:/myfile:http://fakehost/mybase
996 debian: Use dpkg-buildflags in build process.
998 --- 4.2.43 2012/10/19
1000 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
1001 global's SRU service uses a recordPosition scheme starting from zero.
1002 First record's position should be one
1003 according to the standard.
1005 --- 4.2.42 2012/10/18
1007 Allow more namespaces for SRU. This is to allow, for example, an
1008 incorrect namespace returned from server
1009 http://services.igi-global.com/sru .
1011 Minor fixes for compilation on Windows.
1013 --- 4.2.41 2012/10/11
1015 daemon: log total number of bad signals from child on stop so that it
1016 is more easy to spot problems with child worker processes.
1018 retrieval: empty backend name attribute omits element set
1019 from being used in retrieval.
1021 --- 4.2.40 2012/10/04
1023 Implement Solr sort strategy "solr", similar to sru11 sorting.
1024 This will implement the correct parameters on Solr requst to do
1027 --- 4.2.39 2012/09/28
1029 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
1032 MARC: Extra/missing indicator handled for MARCXML.
1033 The indicator length is given in header and is the same for the
1034 whole record. If attributes ind1, ind2 are missing, then content
1035 character defaults to blank. Extra indicator attributes (beyond)
1036 indicator length are treated as an error.
1038 Reformat: delete trailing whitespace
1040 --- 4.2.38 2012/09/17
1042 MARC: fix non-ASCII characters for leader. This is to ensure we can
1043 generate XML in UTF-8.
1045 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
1046 in one node with structure word.
1048 --- 4.2.37 2012/09/04
1050 yaz-json-parse: JSON output may be pretty printed by using option
1053 Increase default value of max message for Z39.50 Init for GFS, ZOOM
1054 and yaz-client. Old value was 1 MB. New value is 64 MB.
1056 --- 4.2.36 2012/08/22
1058 yaz-client: don't display bogus records from SRU servers. Some SRU servers
1059 return more records than given by *maximumRecords*. Skipping those in
1062 record_render: simplify buffer return handling and fix at least one bad
1063 memory reference, that broke the test_embed_record sometimes.
1065 Allow http://user:pass@host notation for yaz_url_exec.
1067 zoomsh: allow shell command to be executed. Via the system(3) call.
1069 yaz_poll: Allow num_fds == 0
1071 yaz-client: fix bad encoding of "itemorder item". The itemorder
1072 item <no> - command forgot to use length of encoded Item Request
1073 package. Error present since YAZ 3.
1075 yaz-ztest: fix bad usage of session handle. Bug was introduced when
1076 result sets were saved (271a9c83).
1078 SRU recordPacking: guess record packing in response rather than looking
1079 at the recordPacking element which, OF COURSE, changed semantics in SRU
1082 Decode SRU 2.0 responses. The official namespace for responses, according
1083 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
1084 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
1085 nature.com's server, however, usee namespace
1086 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
1087 we are now using a glob-expr to match up the namespace. ZOOM C and
1088 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
1089 I can not find a single real example showing the "real" namespace in
1090 the documentation from OASIS. The namespace for requests is different
1091 from responses, but this is not added to YAZ yet, when we don't encode
1094 --- 4.2.35 2012/06/26
1096 zoom/record_render: add support for Base64 decoding fo MARC records
1097 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1098 which will decode base64 + ISO2709 marc-8 encoded material from text node
1101 --- 4.2.34 2012/06/07
1103 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1104 and ZOOM_resultset_facets_names.
1106 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1109 Change APDU dump printing to avoid long leading blanks. For levels 16
1110 or larger the level is shown and the indentation is truncated but
1111 recursed with modula 8. This makes it still reasonable easy to read
1112 - even for nested BER dumps.
1114 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1115 return 0 (incomplete package) in case where the BER package was
1116 considered too nested (return value of -2).
1118 dumpber: lines of level 15 are not indented further. Two spaces per
1119 indentation; indentation 15 or more is indented to a fixed indentation
1120 and augmented with a level=<no> indication.
1122 zoomsh: increase max size of command+args
1124 GFS: No limit in RPN buf size in CQL to RPN conversion.
1126 --- 4.2.33 2012/05/09
1128 New function for daemon utility, yaz_daemon_stop .
1130 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1132 --- 4.2.32 2012/04/25
1134 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1135 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1137 --- 4.2.31 2012/04/23
1139 YAZ daemon utility relays SIGUSR1 to child process.
1141 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1142 would result in en empty database list - which in turn would result in
1143 encoding failure for search.
1145 Fix reading beyond string in yaz_sort_spec.
1147 --- 4.2.30 2012/04/11
1149 Add two new SRU diagnostics:
1150 236: Access to specified database denied
1151 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1153 Document the very useful ZOOM-C option "apdulog".
1155 CQL to RPN: term may be passed through verbatim. This is enabled with
1156 truncation.cql . The assumption being that the term is already CQL.
1158 --- 4.2.29 2012/03/20
1160 record_conv: leader spec may be given for marc element.
1161 The leader spec is given as attribute leaderspec for element marc.
1162 For example to convert a MARC21 record from MARC-8 to UTF-8:
1163 <marc inputformat="marc" outputformat="marc"
1164 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1166 record_conv: allow user-XSLT params. For example:
1167 <xslt stylesheet="MARC21slim2DC.xsl">
1168 <param name="myparameter" value="myvalue"/>
1169 <param name="otherparameter" value="othervalue"/>
1172 record_conv: fix error handling for missing marc charsets.
1174 CQL: fix extra terms in wrong order.
1176 --- 4.2.28 2012/03/06
1178 record_conv: modify new API for conversion types. The conversion types
1179 may be passed in new functions yaz_record_conv_configure_t and
1180 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1182 Avoid mixed statement/variable declare; fixes compilation with Visual
1185 --- 4.2.27 2012/02/28
1187 Add non-standard SRU diagnostic: 235: "Database does not exist".
1188 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1189 Update SRU to Bib-1 diagnostic maps accordingly.
1191 CCL: add two new diagnostics for unsupported masking. The new
1192 diagnostics are: "Embedded truncation not supported" and
1193 "Single charcacter mask not supported".
1195 --- 4.2.26 2012/02/23
1197 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1199 --- 4.2.25 2012/01/11
1201 Build YAZ for Ubuntu Oneiric.
1203 CCL: allow parantheses for proximity operands. For example CCL query
1204 (a) % (b) is now allowed.
1206 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1207 marked dead, rather then being destroyed. If not, the session memory is
1208 being free'd before the search/scan handler is finished. Also destroy
1209 'request' memory in request_release rather than in various places,
1210 which resulted in leaks from time to time.
1212 --- 4.2.24 2011/12/21
1214 cql_sortby_to_sortkeys: honor sort prefix.
1216 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1217 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1218 The rpn2cql family of functions now always returns quoted CQL terms.
1220 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1222 --- 4.2.23 2011/12/15
1224 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1225 sequence is treated as one. For example, &&a=b&&&c& is identical to
1228 --- 4.2.22 2011/12/05
1230 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1231 APDUs for a connection to a WRBUF.
1233 --- 4.2.21 2011/11/23
1235 Fix cql_sortby_to_sortkeys. Completely broken before.
1237 Make CCL's @truncation work again.
1239 --- 4.2.20 2011/11/09
1241 New ZOOM connection setting: tproxy. It's like proxy, but does not
1242 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1243 to set resolved address + port for a connection outside ZOOM itself.
1245 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1247 --- 4.2.19 2011/11/07
1249 Fix uninitialized variable in Solr spell support (could cause SEGV
1250 for SRU response decoding).
1252 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1253 back-end's addinfo through into the ZOOM response addinfo.
1255 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1256 they are separated by a colon and a space rather than simply
1259 --- 4.2.18 2011/10/28
1261 Add support for Solr spell-checking/suggestions through ZOOM.
1262 If a Solr target has been configured correctly for spelling-checking
1263 and suggestions, these will now be returned on the ResultSet option
1264 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1266 --- 4.2.17 2011/09/28
1268 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1269 with a flag whether to substitute escape sequences or not.
1271 --- 4.2.16 2011/09/22
1273 Fix nmem_strsplit_escape to substitute escape char properly.
1275 New option for zoomsh -e , which makes it abort on first error and
1276 return process exit code to indicate success/failure.
1278 YAZ options utility supports special option -- which makes all it treat
1279 all following arguments as non-options.
1281 --- 4.2.15 2011/09/16
1283 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1284 searched if absolute filename is given.
1286 Fix conv_xslt() error-reporting when stylesheet is not found.
1287 (The value of fullpath is meaningless in this situation.)
1289 --- 4.2.14 2011/09/07
1291 Fix problem in CQL sort node creation: un-initialized memory.
1293 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1294 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1295 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1298 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1299 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1301 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1302 will make it possible to use both single-character mask (#) and wildcard (?)
1303 in CCL . Throw diagnostic for left truncation because that is not supported
1306 --- 4.2.13 2011/09/01
1308 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1309 cases using escapes (\-sequences) and masking.
1311 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1312 would result in a read one byte beyond string.
1314 rpn2ccl may use Z39.50 masking for terms (t=z).
1316 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1318 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1319 not --cppflags (which seeems like an error in icu-config).
1321 --- 4.2.12 2011/08/27 RPM package only
1323 cql2ccl: fix conversion of terms: operator characters were not
1326 --- 4.2.11 2011/08/25 RPM package only
1328 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1329 CCL parser will map both # and ? to their regular expression
1330 quivalents (. and .*).
1332 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1333 of reserved CQL characters.
1335 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1336 is, so that they are passed through.
1338 --- 4.2.10 2011/08/24
1340 ZOOM SRU mode: more aggressive re-connect.
1342 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1343 made available as a utility function, declared in <yaz/logrpn.h>
1345 rpn2cql_structure() supports proximity nodes (except that the Type-1
1346 proximity node's "exclusion" binary is ignored, as there is no way to
1347 express that in CQL). Fixes bug #4564.
1349 --- 4.2.9 2011/08/18
1351 Fix SEGV that could occur if set command of zoomsh was given without
1352 value (2nd argument).
1354 Fix SEGV that could occur if unsupported transport was given for
1355 COMSTACK - say https (when SSL was unavailable).
1357 Build yaz-url on Windows too.
1359 --- 4.2.8 2011/08/11
1361 New utility to get web content. Header is url.h. A command line tool
1362 yaz-url is part of the distribution and packages.
1364 Fixes for SSL COMSTACK (when gnutls is in use).
1366 New functions yaz_base64{encode,decode}. Header is base64.h.
1368 --- 4.2.7 2011/08/03
1370 ZOOM C includes HTTP response buffer as additional info if it fails
1371 to decode the SRU response.
1373 Make wrbuf_json_puts available.
1375 --- 4.2.6 2011/07/28
1377 zoom: throw diagnostic for invalid value for option "sru". Before a
1378 bad SRU request was sent.
1380 Adding new utility wrbuf_vp_puts.
1382 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1384 --- 4.2.5 2011/07/21
1386 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1387 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1388 redirect was used at the same time.
1390 MARC line mode decoding: be less picky about length given - first
1391 5 digits of header that is.
1393 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1395 Changes to decoding of SRU records: a record with recordPacking=xml is
1396 modified with a new root element <yaz_record> if the recordData contains
1397 multiple children elements. This is to make the record XML parseable
1400 RPN to Solr conversion: encode special characters.
1402 Generic Frontend Server: fix uinitialized member, stepSize.
1404 --- 4.2.4 2011/06/21
1406 Fix a bug in SRU decoding of records.. The database records stored
1407 had un-initialized memory, but it would only be seen with yaz_record_render
1408 and type_spec="ext" .
1410 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1412 --- 4.2.3 2011/06/17
1414 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1416 --- 4.2.2 2011/06/10
1418 Add new utilities to convert from CQL to CCL . These utilities have
1419 prefix cql_to_ccl defined in cql.h.
1421 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1422 lead to memory heap corruptions when ICU utilities were in use.
1424 --- 4.2.1 2011/06/07
1426 Make compilation work without Libxml2.
1428 yaz-client: remove redundant blanks in display of searchResult-1 term
1431 --- 4.2.0 2011/05/18
1433 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1434 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1436 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1437 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1438 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1439 Note that the CQL sortby spec is only converted when the GFS is already
1440 converting from CQL to RPN (cql2rpn element).
1442 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1443 specify whether to collapse delimitors or not. The existing nmem_strsplit
1444 do collapse (collapse parameter = 1).
1446 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1448 Rename internal func yaz_use_attribute_create. While non-static, this
1449 function is not declared in a public header.
1451 --- 4.1.7 2011/03/15
1453 Add -lCrun when linking with ICU on Solaris.
1455 More quicks character set conversions for OPAC records.
1457 --- 4.1.6 2011/03/10
1459 fix problem with record_render: records were converted (character set
1460 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1462 --- 4.1.5 2011/03/08
1464 SRU: add methods for handling DADS SRU-proxy facets.
1466 Separate OPAC record character set for ZOOM_record. yaz_record_render
1467 allows a character set given as charset=from/opacfrom,to where 'from' is
1468 the character set of a bibliographic record, 'opacfrom' is character set
1469 of OPAC record and 'to' is the target character set.
1471 --- 4.1.4 2011/02/21
1473 yaz-client: show may XML format records. Command show followed by 'format'
1474 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1477 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1480 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1482 --- 4.1.3 2011/01/27
1483 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1485 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1486 this package can be distinguished from other vendors.
1488 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1489 as determined by configure
1491 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1493 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1494 returns no error and no record, the present request is considered
1495 partial (only a subset of the records could be returned by backend), and
1496 so it is appropriate to set Present Status to partial-4.
1498 --- 4.1.2 2010/11/02
1500 Move yaz-config man pages to section 1.
1502 More documentation about Solr.
1504 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1505 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1506 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1507 peers on some Linux systems. However, in general that does not work
1508 so YAZ can not rely on that to work. Debian changed behavior in this
1509 respect from Debian lenny to Debian squeeze (still testing as of Oct
1511 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1513 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1515 --- 4.1.1 2010/10/05
1517 Fix yaz-config output: echo_source not set correctly by configure.
1519 --- 4.1.0 2010/10/05
1521 Solr Web Service support for yaz-client and ZOOM.
1523 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1525 --- 4.0.12 2010/08/17
1527 Z39.50 facet support. Facet specifications are passed for search in
1528 other-information with ASN.1 as defined in facet.asn and OID
1529 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1530 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1531 3 is limit (number of entries to get in response). yaz-ztest returns
1532 dummy facets if a client asks for them.
1534 --- 4.0.11 2010/07/09
1536 CCL fixes: bug 2895 and bug 3539.
1538 GR1-display: add comma in display - was removed by mistake in
1541 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1543 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1545 --- 4.0.10 2010/06/18
1547 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1548 result set from a connection. The result set will be on its own
1549 thereafter; no operations on it will perform retrievals from a target.
1550 Only cached copies are returned.
1552 ZOOM C:fix case for HTTP servers responding with Connection:close.
1553 Ensure that if there is a current task it is resumed (like fetching
1554 more records in a result set) . Bug #3484.
1556 PQF parser: use odr_atoi for Odr_int (not atoi)
1558 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1559 values that contain any non-digits are treated as string attributes
1560 (previously decoding only checked for leading character ([0-9]). PQF
1561 encoding: attribute string values are not surrounded by double-quotes.
1563 --- 4.0.9 2010/05/21
1565 New utility for managing threads - thread_create.h.
1567 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1568 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1569 but YAZ' implementation do.
1571 Fixes for yaz_cond-functions on Windows 7.
1573 DLL export more symbols.
1575 zoomsh: show record do NOT render opac.
1577 Remove *.la files from Debian and RPM packages.
1579 --- 4.0.8 2010/05/11
1581 Debian package libyaz-dev depends on libgnutls-dev again (was
1582 removed in YAZ 4.0.6, but due to Libtool it is still needed
1583 even though yaz-config do not list libgnutls libs).
1585 ZOOM: Use only one WRBUF for returning string results for
1586 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1588 ZOOM: ZOOM_connection do not use a shared pointer to
1589 ZOOM_resultset after ZOOM_resultset is destructed by
1590 user. Reverts to YAZ 4.0.4 behavior.
1592 --- 4.0.7 2010/05/04
1594 record-conv: fix problem with at least one XSL conversion -
1595 due to probably incorrect usage of XML XSL documents.
1597 --- 4.0.6 2010/04/29
1599 Fix yaz-config for static mode and the use of SSL (gnutls).
1601 --- 4.0.5 2010/04/29
1603 Forward decl timeval struct in mutex.h and gettimeofday.h.
1605 yaz-config: fix 'static' mode linking.
1607 --- 4.0.4 2010/04/28
1609 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1610 are wrappers for pthreads or Windows. For Windows these are put in
1611 a separate DLL: yaz_cond4.
1613 libyaz.la (whole source) is compiled with thread. If thread support
1614 is enabled enabled, all source of YAZ is compiled with treading support.
1615 This allows core utilities such as yaz_log to use thread facilities.
1616 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1617 thread utilities. This commit moves mutex utilities (mutex.c) from
1618 libyaz_server.la to libyaz.la.
1620 yaz-json-parse displays leading text until error.
1622 --- 4.0.3 2010/04/09
1624 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1625 patch from Giannis Kosmas.
1627 SRU: no longer URL encode SRU database. The URL for an SRU server is
1628 a URL and such is alreeady encoded - at least when given with leading
1629 http:// or https://. This reverts behavior to YAZ 3.0.50.
1631 Support for new MARC XML notation TurboMARC which like MARCXML is a
1632 complete representation of MARC/ISO2709.. This one, however, is more
1633 compact and allows for faster processing with XSLT. TurboMARC can be
1634 used in the marcdisp.h API, from the yaz-marcdump utility and from
1637 yaz-ztest can be configured - via the database - to perform certain
1638 delays when it performs operations search, present and single record
1639 fetch. This allows testers to make yaz-ztest act as a real or even slow
1640 Z39.50 server. Refer to the yaz-ztest man pages for details.
1642 --- 4.0.2 2010/03/09
1644 wrbuf_destroy allows NULL WRBUF passed to it.
1646 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1648 Add ZOOM_connection_close.
1650 No fixed size buffers for ZOOM shell - bug #3257.
1652 tstodr: make it work on s390 platform.
1654 New icu iterator-functions. The new icu_iter-functions makes it possible
1655 to use ICU chains from many threads.
1657 yaz-client: better syntax check for show command.
1659 --- 4.0.1 2010/01/26
1661 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1664 New simple local-file XML include facility which allows file glob-patterns.
1665 Refer to yaz/xml_include.h.
1667 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1670 ZOOM_record_get supports new parameter "format" which makes it format XML
1673 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1674 JSONText in ECMA-262) is JSONValue, not JSONObject.
1676 --- 4.0.0 2010/01/20
1678 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1679 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1681 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1682 POSIX/Unix builds .so with major version 4.
1684 Remove old LOG_-defines from log.h. They have been obsolete and
1685 undefined by default for the last 5 years.
1687 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1689 GFS: Remove socket (int *fd) from search_rr handler. The socket
1690 descriptor ptr is a facility that allowed a search handler to supply
1691 a socket which would serve as a callback - when search was complete.
1692 This facility has now been in use for years.
1694 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1695 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1696 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1697 returns 'const char *' rather than 'char *. The returned string is
1698 read-only and should not be modified by applications. COMSTACK cs_close is
1699 now a void function - it no longer returns int. No applications check for
1700 the value and the implementations has always returned 0.
1702 ZOOM: use size_t for scan hit counts and str size. Functions
1703 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1704 occ (hit count) and len (string length) are now of type size_t pointer
1705 rather than int pointer. This is to be able to represent large hit counts
1706 and to also just to use the proper type for string length (strlen result).
1708 New JSON parser. Refer to include/yaz/json.h .
1710 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1711 Used to be int in some cases. Many wrbuf_-functions used to return an int
1712 indicating some length.. These return values were never used. And so they
1715 ODR: odr_malloc, odr_total now takes size_t for size.
1717 clone_z_type: fix leak; occurred for encoding failures.
1719 --- 3.0.52 2009/12/03
1721 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1722 bug was introduced in 3.0.51.
1724 --- 3.0.51 2009/12/02
1726 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1728 tcpip comstack: fix leak for getaddrinfo.
1730 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1731 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1732 Decoding of SRU "path" database is performed by private function
1733 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1734 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1736 yaz-client: honor base command for SRU. Change when database setting
1737 is applied for SRU and ensure it is kept when a connection is reset.
1738 Change also the way errors are displayed or SRU (decoding of packages).
1740 --- 3.0.50 2009/11/02
1742 Add support for extra request / response data for SRU codecs and GFS.
1743 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1744 for extra data response buffer and length. For the GFS, both request
1745 and response data (XML) is carried in extra_args and extra_response_data
1746 for the search handler. Patch by Ko van der Sloot.
1748 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1749 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1750 10010). This fixes bug #2113.
1752 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1753 cmdfile included a 'quit' command that would result in a memory violation.
1755 --- 3.0.49 2009/10/01
1757 Make a number of functions defined in xmlquery.c static. These have
1758 never been declared in a public header file (yaz/xmlquery.h) and was
1759 made public by mistake.
1761 Improve speed of character conversions (iconv utilities). This makes
1762 conversions from MARC-8 faster.
1764 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1765 unless type desired is "raw". This will prevent type "xml" from
1766 returning ISO2709 .. Which obviously can not be XML parsed.
1768 Fix memory leak in ZOOM that would occur if option apdulog was used
1769 on a re-used connection.
1771 Frontend server logs HTTP requests.
1773 Frontend server now sends Z39.50 close when it times out (sesssion has
1774 been idle for too long). Versions 2.0.30 and earlier also sent close.
1775 But due to a mistake this was disabled in all versions after that, i.e.
1776 the server would just close the socket immediately.
1778 yaz-client emits a better message when receiving an unrecognised
1779 userInformationField.
1781 Skip zero-length subfields when decoding ISO2709. This rare case happens
1782 if a record has two FS characters in a sequence. Without this patch
1783 there would be a reference beyond char array in using_code_len fragments
1786 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1788 --- 3.0.48 2009/08/28
1790 The show command offered by the zoomsh command now takes a 3d optional
1791 parameter type which is what is passed to ZOOM_record. If the type
1792 argument is omitted, "render" is used.
1794 RPN to CQL conv may use USE string attributes (bug #2978).
1796 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1798 --- 3.0.47 2009/07/08
1800 Function yaz_xml2query allows a diagnostic element in the PQF XML
1801 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1802 code and additional info respectively.
1804 The BER BOOLEAN is now the integral type Odr_bool which still happens
1805 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1806 typedef'd to Odr_int. This is still an integral 'int', but it may be
1807 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1808 ASN-1 compiler as well as programs has been updated to use the new types.
1810 --- 3.0.46 2009/06/08
1812 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1813 only the bibliographic record was rendered. For type=opac, an OPAC
1814 record is only returned if it is present.
1816 iconv: small fix for encoding of advancegreek.
1818 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1820 yaz-client: option auto_reconnect=on really reconnects.
1822 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1824 server: avoid null ptr ref for for yaz_poll errors.
1826 build: fix RPM build for RHEL 5.3.
1828 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1830 --- 3.0.45 2009/03/31
1832 Fixed bug #2709: TCP connect returns Invalid argument.
1834 Fixed compilation for mingw.
1836 Honor charset for raw records (ZOOM_record_get).
1838 Fixed use of errno for threaded mode that was seen on Solaris 10.
1840 Fixed argument passing with blanks in value for Windows Service.
1842 Disable YAZ' own log rotate by default (no 1 GB limit).
1843 The variable l_max_size which specifies the log file limit is set to 0
1844 (DISABLED): This is due to the fact that YAZ is most often deployed using
1845 logrotate. Also YAZ can not perform log rotate because of unsufficient
1846 permissions (setuid).
1848 --- 3.0.44 2009/02/17
1850 List supported encodings in man page for yaz-iconv.
1852 Fixed missing SSL libs for --libs output
1854 Re-established OID record syntax application-xml. Nobody should use it
1855 but we don't want to change soname because of this symbol being absent.
1857 --- 3.0.42 2009/02/02
1859 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1861 Added member named_result_sets for init handler struct for the GFS. This
1862 allows a server to disable named result sets.
1864 Removed OID record syntax application-xml.
1866 Added support for rule-based transliterator for ICU wrapper of YAZ.
1868 Fixed bug #1902: yaz-icu XML output.
1870 Make YAZ checks Emacs friendly.
1872 BITSTRING value shows value. Bug #2346.
1874 ISO2709 decoding: skip control characters from indicator data.
1876 Omit sort key by default in yaz-icu's output.
1878 Allow combined single char options (again) for YAZ' options function.
1880 Utility yaz-marcdump got option to display YAZ version (-V).
1882 Allow YAZ to use ICU 3.4.
1884 Added new ICU test case which illustrates removal of diacritics.
1886 --- 3.0.41 2008/12/29
1888 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1890 --- 3.0.40 2008/12/29
1892 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1895 Fixed bug #2352: yaz-marcdump crashes for certain record.
1897 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1899 Added support for Danmarc2 to UTF-8 conversion.
1901 Added support for ISO5426 to UTF-8 conversion.
1903 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1904 implementation version.
1906 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1908 --- 3.0.38 2008/11/10
1910 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1911 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1913 ZOOM C now interprets databaseName option for ZOOM connection as path
1916 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1918 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1920 Dummy Libxml2 types no longer defined in headers of YAZ'.
1922 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1925 --- 3.0.36 2008/09/26
1927 Various ODR chapter fixes.
1929 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1931 Added missing source for Windows compilation, mutex.c.
1933 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1935 For SRU connections in ZOOM all records up to "count" are now fetched.
1937 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1938 in Windows due to bad error handling for Libxml2.
1940 Added facility for sending arbitrary records (ASN.1 any) using
1941 ZOOM C's Extended service update. Patch by Sam Reynolds.
1943 New options for ZOOM C's connection, logapdu which makes ZOOM log
1946 --- 3.0.34 2008/06/18
1948 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1950 --- 3.0.32 2008/06/12
1952 Fixed memory violation that could occur when decoding UTF-8. This bug
1953 was only present in 3.0.30 of YAZ.
1955 --- 3.0.30 2008/06/06
1957 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1958 GNU TLS is used by default (if found).
1960 yaz-ztest returns OPAC records if a client asks for OPAC.
1962 Improved speed of MARC-8 encoding.
1964 Added support for lossy and loss-less MARC-8 encoding.
1966 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1968 Added new Windows Service wrapper (sc).
1970 yaz-client's itemorder command may now send a file.
1972 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1974 Added new function yaz_log_xml_errors.
1976 Allow (but warn) unknown XML attributes in MARCXML parsing.
1978 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1980 The UTF-8 to MARC-8 conversion now uses a different set of characters
1981 for Greek symbols. Bug #2120.
1983 --- 3.0.26 2008/02/21
1985 Added yaz_daemon (daemon.h).
1987 Fixed bug #2068: pkg-config trouble
1989 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1991 --- 3.0.24 2008/01/28
1993 Document --with-xml2 option.
1995 Added OPAC XML XSD (etc/opacxml.xsd).
1997 Allow glob mask for name attribute in retrieval element for the
1998 generic frontend server's retrieval facility.
2000 Changed yaz_poll_poll to return yaz_poll_except for all returned events
2001 except POLLIN/POLLOUT.
2003 Fixed error handling in cs_listen. Bug #2037.
2005 --- 3.0.22 2008/01/20
2007 Fixed version in yaz/yaz-version.h.
2009 Fixed bug #2027: Crash when closing connection.
2011 Changed configure so that ICU support is only enabled if only ICU
2012 and Libxml2 is available (because the ICU chain is XML based).
2014 --- 3.0.20 2008/01/15
2016 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
2017 is built. Only this DLL depends on the ICU runtime.
2019 yaz-ziffy is no longer part of YAZ. It is distributed separately by
2020 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
2022 Changed license of CCL module to 'Revised BSD'. After consultation with
2023 remaining members of the original EUROPAGATE consortium, we are re-issuing
2024 the CCL module without a separate license. The software was developed by
2025 Index Data as part of a research project. The special license was included
2026 to help feed usage information back to the project consortium to support
2027 project evaluation. At this time, the project consortium has long-since
2028 disbanded, and the majority of the original principals have retired. At the
2029 same time, we have significantly modified the software during the following
2030 years, to the point where very practically no original code remains. To
2031 simplify re-use of the software, we have contacted those members of the
2032 consortium who could be reached, and agreed to re-issue the module as a
2033 proper part of the YAZ package.
2035 Tcl scripts uses /usr/bin/tclsh as preferred shell.
2037 CQL closer to being version 1.2 compliant. CQL also allows free-form
2038 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
2041 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
2042 bug could make Extended services handling crash in the ZOOM layer. This
2043 bug was only present in YAZ 3.0.18.
2045 --- 3.0.18 2007/12/19
2047 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
2050 yaz-marcdump reads and writes collection wrapped records.
2052 Handle OPAC for record conversion module.
2054 Fixes for ICU wrapper.
2056 Allow ICU libs to be controlled with --with-icu .
2058 --- 3.0.16 2007/11/12
2060 Added yaz_poll which is a wrapper for select/poll. When poll is available
2061 and non-buggy, it is used, by yaz_poll . This allows more than 1024
2062 sockets to be in use.
2064 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
2065 functionality through an XML based configuration (ICU chain). This system
2066 is useful for search facilities such as Pazpar2 and Zebra that needs to
2067 perform tokenization of indexed material. The ICU code in a separate
2068 library libyaz3_icu.a.
2070 Added HTTP tunnel facility for COMSTACK, bug #1752.
2071 This is a facility that allows a Web proxy, such as squid, to tunnel
2072 Z39.50 traffic. This facility is "transparent" to must applications
2073 using YAZ. It's enabled by using pseudo transport connect: followed by
2074 the proxy address, followed by command, then follwed by he regular
2075 "virtual" addresss. For example,
2076 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
2078 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
2080 --- 3.0.14 2007/09/21
2082 Fixed bad memory reference in ZOOM_record - cuased by member not being
2083 initialized. This was a problem only in YAZ 3.0.12.
2085 Fixed bug in conversion from MARC to XML: Non-XML characters in control
2086 fields were not removed.
2088 Changed the way C code is generated from codetables.xml. Made a MARC-8
2089 conversion trie for each characterSet section rather than codeTable.
2090 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2091 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2093 --- 3.0.12 2007/09/12
2095 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2096 from ZOOM_record_error).
2098 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2100 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2102 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2104 Better SRW-to-Bib-1 diagnostic mapping.
2106 ZOOM C and yaz-client announces SRU version 1.2 by default.
2108 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2111 Fixed in yaz_sru_decode to allow other version than 1.1.
2113 --- 3.0.10 2007/08/22
2115 Added support for SRU scan for ZOOM.
2117 Added support for the use of the older versions or Extended Service
2118 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2119 set to the version , 1=first, 2=second, 3=third. The third version is
2120 what ZOOM C has used so far. And that, obviously, is the default.
2122 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2123 therefore in Zebra and in SimpleServer-based applications). The new
2124 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2125 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2126 which is passed into the back-end search callback function.
2128 Added support for HTTP Basic authentication in clients: the SRU/W
2129 codec encodes the username/password elements of the PDU structure
2130 appropriately, and these may be set using the "user" and "password"
2131 options in ZOOM-C applications (the same options that are used for
2132 Z39.50 authentication).
2134 --- 3.0.8 2007/06/25
2136 Fixed bug #1208: SSL appears to be broken in ZOOM.
2138 Fixed bug #1206: Libxml2 include path weirdness.
2140 Added oid_name_to_dotstring.
2142 Allow elementSetName to be specified for ZOOM C record update.
2144 Allow waitAction to be specified for ZOOM C based for Extended Services.
2146 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2147 syntax OID. Bug introduced in YAZ 3 series.
2149 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2151 --- 3.0.6 2007/06/06
2153 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2154 directory. yaz-client now reads commands from file given by option -f
2155 if specified; then tries to read .yazclientrc in current directory.
2156 Failing that, it reads .yazclientrc from user's home directory.
2158 Added support for correlationInfo Note and ID for Record Update via
2161 Added yaz-client command querycharset which specifies character set for
2162 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2163 (termListAndStartPoint).
2165 Charset ISO5428:1984 is an alias for ISO5428-1984.
2167 Implemented a way to perform scan in a result set using Z39.50. This
2168 is achieved by attaching the result set name in the characterInfo
2169 (type InternationalString) of OtherInformation in the Scan Request PDU.
2170 The result set is identified in the otherinformation by the new OID:
2171 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2172 This allows for scan in result set and faceted search . Zebra did some
2173 of this in the APT term using attribute type 8 and value being result
2174 set. Using the OtherInformation approach for this is cleaner and easier
2175 to work with in proxies and the like. This facility can be used in
2176 yaz-client using new command setscan which takes a result set as first
2177 argument, start position (APT) as second.
2179 Changed decoding of SRU XML packed records to deal with servers that
2180 have recordData with XML data with multiple root nodes. Also make
2181 comparison for recordPacking case insensitive. Again, one server
2182 returns "XML" where others return "xml".
2184 For SRU responses allow Content-Type application/xml as well as text/xml.
2186 --- 3.0.4 2007/05/21
2188 Fixed bug in character set conversion of BER strings. Bug introduced
2191 --- 3.0.2 2007/05/08
2193 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2195 For OID class, use oid_class consistently.
2197 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2200 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2201 character set for bibliographic information interchange". By Giannis Kosmas.
2203 Added documentation on new OID API.
2205 --- 3.0.0 2007/05/02
2207 Changes to generic frontend server interface: added new member
2208 'query_charset' for bend_initrequest structure. A backend init handler
2209 should set this member to its native character set for query terms.
2210 When defined, the frontend server logic will announce this character set
2211 to a client if the negotiationModel bit is set by the client. All server
2212 implementors are encouraged to specify this. If a backend server does not
2213 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2215 Added CCL utility to remove terms (stop words) from resulting RPN
2216 tree. This is handled by functions with prefix ccl_stop_words_ .
2218 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2219 terms in RPN queries.
2221 Clean-up the CCL API. Moved some internal structures from ccl.h to
2222 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2223 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2224 This is replaced by ccl_parser_find_str which takes a string instead.
2226 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2227 libyaz.la is the core of YAZ except the generic frontend server and
2228 does not depend on POSIX threads anymore. libyaz_server.la is the
2229 generic frontend server facilities and uses POSIX thread functionality
2230 if available. The libyaz.la no longer depends on POSIX threads because
2231 the number of global structures is limited. NMEM no longer re-uses blocks
2232 between threads ; it simply free's memory immediately but allocates in
2233 "large" chunks as usual. We don't expect any performance penalties
2234 because of this. The yaz_log system is still using a global log_level so
2235 caution must be taken when modifying it with yaz_log_init_.. +
2236 yaz_log_mask_str. This, however, should not cause any trouble because
2237 these functions are called during initialization of application code
2238 anyway. `yaz-config --libs server` returns libs for server applications;
2239 `yaz-config --libs` returns libs for non-server applications.
2241 New OID database - with public definitions in oid_db.h. Removed old OID
2242 database including the head oid.h and definitions such as enum oid_value
2243 and struct oident. The new OID database uses the same string names as
2244 before but the 'protocol' is gone. There are now only two representations
2245 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2246 converts from string to OID; functions with prefix yaz_oid_to_string
2247 converts the other way.
2249 Change to emit_term() in CQL-to-PQF query translation: when a term has
2250 the /regexp relation modifier, do not process it for leading and
2251 trailing "^" and "*", which have quite different meanings in regular
2254 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2255 write handlers no longer carries a 'last' parameter. This will make
2256 yaz_iconv flush "less" characters. A flush is performed by call to
2257 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2259 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2260 removed, because function yaz_query_to_wrbuf does the same.
2262 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2263 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2265 Deprecated MARC utility functions removed.
2267 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2270 Branch split: YAZ_2_1_55_branch
2272 --- 2.1.54 2007/03/16
2274 Fix to ZOOM-C so that transparent reconnection is properly handled on
2275 connections that are in asynchronous mode.
2277 Fixed compilation on OpenBSD 4.0.
2279 Large strings in GRS-1 records are now properly displayed in yaz-client.
2281 Added character conversion support for "advancegreek"; based on patch from
2284 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2285 sequence is met. Before the error was not set so it would be unknown.
2287 Adjust yaz-marcdump MARC reader so that it skips until record separator
2290 --- 2.1.52 2007/03/07
2292 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2293 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2294 fd_set structure used as a bitmask for the FDs to be selected on.
2296 Using ACX_PTHREAD macro to check for POSIX threads.
2298 Fixed have-vsnprintf check.
2300 --- 2.1.50 2007/02/23
2302 Fixes for configure on BSD. Bug #900.
2304 Added snprintf/vsnprintf wrappers for systems that don't have
2305 limits (heavens forbid).
2307 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2308 created before all previous tasks were completed and removed from the
2309 task queue, the new task could be removed by a mistake.
2311 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2313 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2315 Fixed bug #832: Problem with MARC/charset in yaz-client.
2317 Fixed bug #668: save command line history for yaz-client.
2319 Fixed bug #830: pkg-config support.
2321 --- 2.1.48 2007/01/23
2323 Extended ZOOM result set options with two options that may be read by
2324 a client: resultSetStatus and presentStatus with values as specified for
2326 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2328 Fixed bug #827: Using SSL fails on Debian etch.
2330 Fixed bug #826: Weird looking chars for set of MARC records.
2332 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2333 that is treated as an ItemOrder with itemRequest being an XML document
2334 external. The value of "doc" is the content.
2336 Extended the GFS search facility. New member of bend_search_rr
2337 'estimated_hit_count' signals that hits is known to be an estmate
2338 (higher or lower than real hit count). New member 'partial_resultset'
2339 signals that the search was partial (hit count is lower or equal than
2340 real hit count). For Z39.50, the information is stored in resultSetStatus
2341 member of SearchResponse APDU. For SRU, the information is signalled
2342 via SRU diagnostic 59: "Result set created with valid partial results
2345 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2347 --- 2.1.46 2007/01/13
2349 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2351 Added ZOOM_connection_peek_event.
2353 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2354 the following new functions:
2355 ZOOM_event_nonblock, ZOOM_connection_process,
2356 ZOOM_connection_get_{socket,mask,timeout},
2357 ZOOM_connection_fire_event_{timeout,socket}.
2358 The existing blocking event handler, ZOOM_event, is a wrapper for the
2359 + blocking ZOOM_event_sys_{poll,select}.
2361 Implemented function ccl_xml_config which parses XML version of CCL
2362 configuration (bug #798).
2364 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2366 Added timings utility (yaz/timing.h)
2368 --- 2.1.44 2007/01/03
2370 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2373 Fixed bug #779: Rotation of apdu.log fails.
2375 Fixed for character set conversions:
2376 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2377 Honor G1 set in MARC-8 decoding.
2379 --- 2.1.42 2006/12/17
2381 Fixed bug #775: char conversion does not handle Alternative UTF-8
2384 Implemented function yaz_marc_read_line which parses MARC line format
2385 records. There is a wealth of formats out there. So far, this function
2386 reads line records produced by yaz_marc_write_line.
2388 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2389 more generic and easier to remember(!) options: -i format and -o format
2390 which specifies input format and output format respectively - where
2391 format is one of "marc", "marcxml", "line", "marcxchange".
2393 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2394 does not print anything except warnings for records.
2396 For yaz-marcdump, added support for MARC split into files (-s) with a given
2399 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2400 spec, at http://www.loc.gov/standards/sru/record-update/
2401 This has changed the binary layout of the following structs:
2402 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2403 bend_update_rr . Patch by Ko van der Sloot.
2405 Added GFS utility function bend_assoc_is_alive which returns 1 if
2406 association is still alive (client is connected); 0 otherwise (client
2407 closed connection). This allows busy servers to stop working for
2410 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2411 been a separate piece of software. This version of ziffy has been modified
2412 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2414 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2416 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2417 Client code may now interrogate options such as "init_opt_sort" to
2418 find out whether the server claims to support various options.
2420 --- 2.1.40 2006/11/27
2422 Added utilities yaz_{set,get}_esn to set/get element set name from
2425 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2426 of YAZ and has been so since YAZ 2.1.10.
2428 Implemented ZOOM_record_error which returns error information for
2429 record (surrogate diagnostic).
2431 --- 2.1.38 2006/10/31
2433 Updates for SRU Update by Ko van der Sloot:
2434 1. Changed name from "operation" to "action"
2435 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2436 versions in the code, marked as 'backward compatible'.
2437 3. Added diagnostics for SRU Update.
2439 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2441 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2443 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2445 For GFS, fixed problem with SRU diagnostic 'First record position out of
2446 range' being issued for 0 hits.
2448 zoomtst10 part of Windows Build.
2450 --- 2.1.36 2006/10/13
2452 Implemented yaz_filepath_comp which splits a path into file path
2453 components (required by Zebra 2.0.3+).
2455 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2456 BSD inspired license until now so this should not have any real impact on
2457 anybody. See http://www.opensource.org/licenses/bsd-license.php
2459 Fixed bug #687: Missing log lines.
2461 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2464 Fixed bug #689: SRU diagnostics to be added.
2466 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2467 whether a connection is idle (no more work do do).
2469 --- 2.1.34 2006/10/04
2471 Change type of optval from long to int for invocation of setsockopt with
2472 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2474 Added support for specifying the max log file size for the Generic
2475 Frontend Server. The size is given with option -r.
2477 --- 2.1.32 2006/09/21
2479 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2481 --- 2.1.30 2006/09/17
2483 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2486 Fixed bug in Generic Frontend Server that could cause a server to stop
2487 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2489 For the generic frontend server, the maximum record size is used as maximum
2490 size of incoming packages (SRU + Z39.50). The value until was previously
2491 only used in Z39.50 Init negotiation and, later, in a session controlled
2492 sizes of records returned. This is controlled using -k option. It can be
2493 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2495 --- 2.1.28 2006/09/04
2497 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2500 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2502 New option for yaz-marcdump -lpos=value which allows setting a portion
2503 of MARC header to a certain value.
2505 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2507 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2508 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2510 --- 2.1.26 2006/08/15
2512 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2515 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2517 --- 2.1.24 2006/08/08
2519 Fixed MARC ISO2709 encoding routines to deal with character set
2522 Minor changes to GFS logging. Database included in search request log
2525 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2526 cached/multiple records.
2528 Shared libraries are built by default on Unix+configure.
2530 Changed cql2pqf transformation to use a different evaluation order. The
2531 new order is: always, relation, structure, position, truncation, index
2532 and relationModifier. Old order was: always, relation, relationModifier,
2533 structure, index, position, truncation. Note that the the latter ones
2534 override former ones for identical attributes.. The new scheme means that
2535 it is possible to override any existing attribute with a relationModifier.
2536 And also that it is possible to override everything for the index rule
2537 (except the ones listed in relationModifier). No order is perfect but this
2538 one, we believe, covers more real cases.. The "always" should have been
2539 called "default", since the attributes there can be overridden with all
2542 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2543 compilation phase, but also for yaz-config --cflags output. This allows
2544 us to have public headers with Libxml2 stuff in them . It should also,
2545 eventually, make Libxml2 checks redundant in packages using YAZ, such
2548 --- 2.1.22 2006/06/15
2550 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2551 stored in uri, message and details.. Previously diagnostics were stored
2552 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2553 compatibility.. but he's probably the only one affected, so.
2555 Added support for CCL, compiled on the client side, in ZOOM-C. This
2556 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2557 input; the resulting query objects can be used for for searching with
2558 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2560 YAZ' configure searches for OpenSSL by default.
2562 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2563 SL_CTX_use_certificate_file. See
2564 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2565 for more info. Thanks to Ko van der Sloot.
2567 --- 2.1.20 2006/06/02
2569 Bug #600: SRU GET, POST support for yaz-client. Introduced
2570 command 'sru' which selects method SOAP/GET/POST.
2572 Allow missingValueAction to be specified for the sortspec string -
2573 function yaz_sort_spec. By default, the missing value action is null.
2574 Use ! to specify "abort". Use = followed by stringvalue to specify default
2577 Ensured that Present-handler (if defined) is called in GFS before any call to
2578 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2579 searchRetrieve requests.
2581 Documentation for YAZ is now based on the Docbook XML/XSLT using
2582 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2583 is no longer depending on jade/openjade or docbook-to-man scripts.
2584 PDF is no longer part of the distribution - but can optionally be
2585 made using DSSSL/jadetex or FOP.
2587 Added retrieval handling support in Generic Frontend Server to support
2588 conversion between MARC/XML as well as XSLTtransforms. See
2589 etc/yazgfs.xml for an example.
2591 Added Authentication support to Generic Frontend Server in SRU
2592 mode. Authentication using HTTP Basic is supported, as is the use
2593 of 'x-username' and 'x-password' parameters in the request itself.
2595 Added support for a new character set MARC8s identical to MARC8 except
2596 that it converts combined characters to single Unicode characters in the
2597 Latin-1 range (when possible).
2599 --- 2.1.18 2006/04/24
2601 ASN.1 compiler 0.4: generates brief Doxygen file header for
2602 generated .h/.c files.
2604 Utility yaz_iconv now supports conversion to MARC-8.
2606 New facilities for the MARC module. The reading - and writing of
2607 content are separate methods for the yaz_marc_t handle. The following
2608 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2609 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2610 format). Write functions have prefix yaz_marc_write_.. The existing
2611 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2612 available. Removed support for OAI-MARC and simplexml (not the
2613 simplexml from PHP5).
2615 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2616 to be returned for this connection.
2618 --- 2.1.16 2006/03/31
2620 Allow multiple languages and charsets to be specified with
2621 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2622 negcharset iso-8859-1,utf-8
2624 Translation of proximity nodes from CQL into PQF now works.
2626 Moved to automake 1.8, 1.9.
2628 Added function yaz_log_set_handler which allows a log handler to be
2629 installed. This handler will be called for all log messages. Output
2630 to file is also produced; but that can be disabled by passing NULL
2631 fname to yaz_log_init_file.
2633 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2635 For SRW (including GFS), accept application/soap+xml as content-type
2638 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2639 produces NO stylesheet reference even if a default stylesheet is specified
2642 --- 2.1.14 2006/03/14
2644 Updated Windows package to include yazd.dll + yazd.lib for the
2645 Development component.
2647 If the environment variable YAZ_LOG is set, then it is used as a
2648 string indicating the default level of logging to use if not
2649 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2650 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2651 used as before. So, for example, to omit warnings from YAZ logging,
2652 export YAZ_LOG=-warn
2654 cql_transform() now map structure and other attributes before indexes,
2655 so that index-specific structures and other attributes can override
2656 defaults. So now a combination of mapping specifications such as:
2658 index.dc.date = 1=date-modified 4=5
2659 does the right thing.
2661 cql_transform() now also respects the "always" mapping specification,
2662 which establishes an initial set of attributes to be used for all
2663 terms except where overridden by more specific attributes associated
2664 with the index, relation or modifier.
2666 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2667 which mode to use; one of "post", "get" or "soap" (SRW, default).
2669 Fixes for yaz_iconv routines: changed trie-based character set conversions
2670 to use only non-negative values for bit fields due to Sun's C compiler not
2671 supporting negative values.
2673 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2674 sequences where not read correctly. Fix by Rustam Usmanov.
2676 Updated win/makefile to use options, settings which makes things
2677 compile with VS C 2005.
2679 --- 2.1.12 2006/02/01
2681 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2683 In ZOOM socket code, use select instead of poll on MacOSX.
2685 ZOOM-C now support client-side compilation of CQL into RPN that is
2686 sent to the server, enabling CQL to be used against all Z39.50
2687 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2688 ZOOM_query object, and submit it using ZOOM_connection_search().
2689 The CQL-to-RPN translation uses a configuration file, the name of
2690 which must be specified in the Connection's "cqlfile" option.
2692 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2693 function, which takes as its start-term parameter a ZOOM_query object
2694 (which may have had either CQL or RPN set into it).
2697 --- 2.1.10 2005/11/29
2699 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2700 GFS to support this as well. Backend handler, bend_srw_update, does the
2701 update work. Code contributed by Ko van der Sloot.
2703 Allow retrieval of Search Result-1 information in ZOOM by the use of
2704 options that are attached to a result set. ZOOM documentation updated
2707 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2708 UTF-8 conversion. Patch by Raj Patel.
2710 Added option -m to GFS to control formatting of timestamps in log file.
2712 Added 'exit' as synonym for 'quit' in yaz-client
2714 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2715 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2716 for the new members. Patch by Ko van der Sloot.
2718 Added support for SRU POST. It is supported for content-type
2719 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2721 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2722 Instead make the library libyaz.la multi-threaded. Threading as a whole
2723 can still be disabled by configure option --disable-threads. Previosly,
2724 with older GLIBCs there were problems with MT libs under Apache. This
2725 has now been fixed a long time ago.
2727 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2730 CQL module modified to be case insensitive for relations/indexes/operations.
2732 Fixed bug in CQL transform code: incorrect value relationModifieder
2735 Added 'show all' command for yaz-client which retrieves all results
2738 Added new yaz-client, xmles, which takes a (private) OID and
2739 a document to be sent as an extended service request.
2741 Describe new yaz-client commands wait_response and set_auto_wait.
2743 Increase TCP/IP listener backlog from 3 (which I am guessing was
2744 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2745 that the socket will queue as many incoming connections as it's able
2746 to handle ongoing connections. In other words, it will never now
2747 refuse a connection that it would be able to handle merely because
2748 it's not got around to accepting() enough of the pending connections
2749 yet. This is the behaviour anyway under Linux, where the listen()
2750 argument is ignored; but not under BSD and on systems such as
2751 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2752 YAZ-based servers should now be uniform across operating systems in
2755 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2756 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2757 This allows yaz-marcdump to read large MARC batches (>2 GB).
2759 Modified all YAZ source files - except the source which is auto-generated
2760 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2763 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2764 corresponding to the existing *_setl() function. These allow option
2765 values containing arbitrary valuues.
2767 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2768 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2769 except that it returns an indicator of whether or not the sort
2770 criterion was accepted (0 for OK, -1 for invalid).
2772 --- 2.1.8 2005/06/07
2774 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2775 MARC output rather than returning "new" buffer.
2777 yaz-client warns about unknown init options.
2779 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2781 --- 2.1.6 2005/05/24
2783 Added support for SRW sort in Generic Frontend Server. Patch
2784 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2785 sortKeys - or NULL if none is provided.
2787 Fixed bug #307: It was impossible to specify indefinite/no timeout
2788 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2791 Added support for multiple languages and charsets to be specified in
2792 ZOOM. Each charset/language is separated by a blank. If negotiation is
2793 in effect in init-response, Option
2794 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2795 Code based on patch by Vasiliy Osadchuk.
2797 Fixed bug #306: infinite recursion that occurred when calling
2798 yaz_log_level_init as the first call (before other log level or
2801 Fixed bug in scan handling in front end server: if preferred-Position-In-
2802 Response was non-present, a NULL pointer referece was performed.
2804 --- 2.1.4 2005/04/26
2806 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2807 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2808 now defined for all those error codes. So instead of putting 109 in
2809 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2810 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2812 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2815 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2817 Program yaz-client now exits and produces an error message if multiple
2818 Z39.50 servers are specified on the command line (none or one allowed
2821 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2824 --- 2.1.2 2005/03/16
2826 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2828 Fixed bug #272: Preserve spacing for CCL terms.
2830 --- 2.1.0 2005/03/14
2832 Added support for virtual hosts and multiple backend servers for
2833 the YAZ frontend server. The configution is XML based and
2834 support specificition of CQL to RPN mappings and explain information.
2835 See section "Virtual Hosts" in the YAZ manual.
2837 Extended OPAC display utility. OPAC display utility renders
2838 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2839 to supplement yaz_marc_decode_wrbuf.
2841 Fixed a bug in MARC decoder that could caused it to crash for some
2842 invalid MARC records. More diagnostics and warnings where added in
2843 XML output (warnings, etc are stored in comments).
2845 --- 2.0.34 2005/02/08
2847 Fixes for UNIX domain sockets. Bug #261.
2849 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2851 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2852 Added yaz_marc_subfield_str which defines subfield lead string which is
2853 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2854 yaz_marc_endline_str which defines end of fields string used in
2855 YAZ_MARC_LINE format. Default string is newline.
2857 Experimental support for MarcXChange. This format can be produced
2858 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2859 http://www.bs.dk/standards/MarcXchange.xsd
2861 Added yaz-client commands scansize that sets maximum number of
2862 entries to be returned by scan.
2864 --- 2.0.32 2005/01/11
2866 Added support for SRW scan in yaz-client and Generic Frontend Server.
2868 * Added whereInList member to SRW Scan Term.
2870 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2872 Fixed NMEM system to return aligned blocks on the smallest boundaries
2873 that are suitably aligned for all possible types on the particular
2874 architecture YAZ is being built for.
2876 --- 2.0.30 2005/01/04
2878 Fixed numerious warnings that was issued with newer versions of GCC.
2880 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2881 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2884 Make YAZ Generic Frontend Server slightly faster.
2886 Enhance (and reduce) logging for Generic Frontend Server.
2888 Revert YAZ log system so that it flushes every write operation
2889 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2891 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2892 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2893 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2894 will effectively disable old definitions.
2896 --- 2.0.28 2004/11/09
2898 Added yaz_log_time_format which specifies log format using
2901 Added yaz_log_module_level which returns mask for a module. Value
2902 is non-zero mask a if module is enabled; zero if disabled.
2904 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2905 in include/yaz/cql.h.
2907 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2909 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2911 Fixed bug #172: RPM builds does not enable SSL.
2913 Doxyfile.in part of dist. Doxyfile generated by configure.
2915 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2916 are given and the corresponding component does not exist.
2918 Extend CCL documentation in YAZ reference. Describe r=r.
2920 --- 2.0.26 2004/10/01
2922 Fixed MARC->MARCXML conversion to properly deal with
2923 fields, subfields, indicators having non-ASCII characters.
2925 Fixed MARC->MARCXML conversion so that ASCII control characters
2926 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2929 Added YAZ GFS support for conversion from Z39.50 surrogate
2930 diagnostics to SRW surrogate diagnostics.
2932 Bug fix: YAZ GFS did not return schema in explainResponse.
2934 --- 2.0.25 2004/09/30
2936 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2937 now converts recordSchema to elementSetName as well as schema URI.
2939 Fixed bug in COMSTACK that prevented HTTP request packages from being
2942 --- 2.0.24 2004/09/29
2944 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2945 does not require white-space before and after the dash in a range, e.g.
2946 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2949 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2950 due to new GCC removing "redundant" code.
2952 Added yaz-client commands scanpos and scanstep that sets preferred
2953 position and step-size for scan.
2955 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2957 Added CCL utility ccl_qual_buf which parses one or more CCL
2958 spec lines in a buffer.
2960 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2961 of name and value - ignoring empty lines and comments.
2963 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2965 Added odr_get_element_path which returns current element path for an
2966 ODR handle. This utility is useful in error handling or user-defined
2969 Added ODR_PRINT utility odr_set_stream which is is a more generic
2970 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2971 to a write function and pointer to close function. The close function - if
2972 non-NULL - will be called during odr_destroy.
2974 Fixed bug in CCL parser where truncation char was not removed from
2975 right side when truncation=both was in effect.
2977 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2980 --- 2.0.23 2004/08/11
2982 Fix buffer overrun in CQL parser when dealing with proximity (%).
2984 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2985 to UTF-8/UCS conversion is now only based on codetables.xml.
2987 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2989 --- 2.0.22 2004/08/06
2991 Add support for more "commit changes" in ZOOM (uses Extended Services).
2993 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2996 Yet another small fix for configure of SSL.
2998 --- 2.0.21 2004/05/14
3000 Fix SSL libs for configure when --with-openssl=DIR is given.
3002 --- 2.0.20 2004/05/10
3004 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
3006 SSL comstack now uses yaz.pem certificate file on server side
3007 by default. Certificate filename can be configured by calling
3008 comstack function cs_set_ssl_certificate_file before cs_bind is used.
3010 Fix bug regarding multiple calls to ZOOM_connection_connect.
3012 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
3014 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
3015 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
3017 ZOOM now allows inspection of X509 peer certificate for verification.
3018 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
3020 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
3021 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
3022 as "modular" but it simplifies things.
3024 Added cs_get_peer_certificate to that returns peer X509 PEM.
3026 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
3027 NULL if SSL is unavailable.
3029 Documentation about MARC decoding tools.
3031 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
3033 --- 2.0.19 2004/03/30
3035 Rename CHANGELOG to NEWS to follow GNU style packing.
3037 Fix bug with missing initialization of member in init_diagnostics.
3038 This bug affects threaded version of GFS server.
3040 --- 2.0.18 2004/03/20
3042 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
3045 Ensure zlib.dll is packed with Windows install.
3047 --- 2.0.17 2004/03/17
3049 Fix encoding of xsd:string to use text instead of CDATA.
3051 Fix endless loop in CQL parser with unbalanced ".
3053 Use a more compact way to store MARC-8 conversion tables.
3055 --- 2.0.16 2004/03/16 Debian only
3057 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
3060 Update CQL parser to use new CQL 1.1 modifiers for booleans and
3065 --- 2.0.15 2004/03/01
3067 Another fix for decoding of XML packed records.
3069 --- 2.0.14 2004/02/25
3071 Fixes for Chunked encoding. White space not ignored after length spec.
3073 Update NS and use default NS for SRW diagnostic elements.
3075 --- 2.0.13 2004/02/23
3077 Implement ZOOM_resultset_cache_reset which resets record cache.
3079 Implement ZOOM_resultset_sort which sorts a result set.
3081 Implement chunked HTTP transfer.
3083 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
3085 --- 2.0.12 2004/02/16
3087 Added member 'schema' to bend_explain_rr structure so that backend
3088 can specify explain record identifier. Defaults to Zeerex 2.0.
3090 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3092 --- 2.0.11 2004/02/16
3094 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3097 Added init command for yaz-client which sends "extra" init request.
3099 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3100 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3102 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3104 Make ZOOM error code for "invalid query".
3106 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3108 --- 2.0.10 2004/02/05
3110 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3113 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3115 Added option -p <file> to make Generic Frontend Server to write PID file.
3117 Added option -D to put Generic Frontend Server in background on its own.
3119 Make ZOOM C recognize option "password". If unset, "pass" is used
3120 (for backwards compatibility).
3122 Fixed a bug in Generic Frontend Server that could make it crash if a
3123 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3126 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3127 Must be issued before open, in order to be in effect.
3129 --- 2.0.9-6 2004/01/12 Debian/Windows
3131 Make the SRU server more picky WRT unknown params, etc.
3133 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3135 New YAZ client command, options, that sets Z39.50 options.
3137 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3138 options from a string of tokens (one token for each option bit).
3140 Update SRW diagnostic code messages.
3142 --- 2.0.9-5 2004/01/07 Debian/Windows
3144 Handle user defined stylesheet for SRW/SRU.
3146 --- 2.0.9-4 2004/01/06 Debian/Windows
3148 Fix bug in decoding of Content-Length.
3150 --- 2.0.9-3 2004/01/06 Debian/Windows
3152 Fix a bug with decoding of XML packed records.
3154 --- 2.0.9-2 2004/01/05 Debian only
3156 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3158 Fix bug in SRW/SRU diagnostics decoding.
3160 --- 2.0.9 2004/01/05
3162 Fixed bug in Generic Frontend Server which could drop records exceeding
3163 preferred message size. Reported and fixed by Irina Dijour.
3165 Fixed calculation of package size for structured records in Generic
3166 Frontend Server. Reported and fixed by Irina Dijour.
3168 Fixed namespace for SRW/SRU diagnostics.
3170 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3172 --- 2.0.8 2003/12/22
3174 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3175 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3178 CQL changes to reflect recent changes to the specification:
3179 * Documentation talks about context sets instead of index sets.
3180 * Documentation talks about indexes instead of qualifiers.
3181 * The CQL-to-PQF transformer's configuration file now uses
3182 "index.set.name = <attributes>" instead of the old form
3183 "qualifier.set.name = <attributes>". (Both forms are still
3184 understood but the latter is deprecated.)
3185 * CQL terms with no explicit index specified are now interpreted as
3186 cql.serverChoice instead of srw.serverChoice (which of course
3187 behaves exactly the same.)
3189 --- 2.0.7 2003/12/16
3191 MARC conversion can now generate ISO2709 output in another
3192 character set. yaz-marcdump uses this facility if you invoke it
3195 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3196 functions from there can be used from C++.
3198 --- 2.0.6 2003/12/04
3200 Frontend server now transfers memory from decoded packages to stream
3203 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3204 references to show up.
3206 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3207 the ZOOM Abstract API. The older names for the same options are still
3208 also supported for the benefit of old applications.
3210 ZOOM-C supports "implementationId" and "implementationVersion" options
3211 to go along with "implementationName". These allow the user code to
3212 specify identification strings to be sent to servers.
3213 Add OID for the new ExtLite attribute set.
3215 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3216 as requested/supplid by Ere Maijala <ere@atp.fi>
3218 For generic frontend server, reverse the order of
3219 "toolkit-supplied / application-supplied" strings sent as implementationId,
3220 Name and Version. Also, remove the spaces around the slash. This brings
3221 the GFS in line with the behaviour of ZOOM-C on the client side.
3223 Add function ZOOM_scanset_display_term.
3225 yaz-client shows scan displayTerm if present.
3227 Utility yaz-iconv is now installed by default along with the man page
3230 Extend configure check for OpenSSL to use pkg-config where available (such
3233 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3234 server to specify uid/gid/mask for socket using the format
3235 unix:[user=uid,][group=gid,][umask=mask,]file=path
3236 If file= is omitted the existing format is assumed, e.g.
3238 in which case the mask is 0666 (rw for everybody).
3240 Major restructure of YAZ source. All source in libyaz is in src directory.
3241 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3242 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3244 Added man page for utility yaz-marcdump (used to be called marcdump).
3245 yaz-marcdump is installed by 'make install'.
3247 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3248 of incoming package failed.
3250 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3252 Change prototype of odr_perror: add const to message string.
3254 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3256 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3257 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3258 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3259 DNS lookup. There should not be any compatibility problems with this
3260 assuming that blocking=1 or 0 is used.
3262 Fix bad reference in UNIX comstack in function cs_addrstr.
3264 Fix for compilation on AIX.
3266 The generic front-end server (server/seshigh.c) now supports returning
3267 Init diagnostics to the client in User-information-field, in
3268 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3271 --- 2.0.4 2003/09/04
3273 Allow any CQL relation (not just all,any,exact,scr).
3275 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3276 that features the same UI.
3278 Implemented command update0 in YAZ client which is equivalent to
3279 update but uses old of Ext Update ASN.1.
3281 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3282 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3283 Previously no OID was used for this info.
3285 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3286 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3287 returns 'malformed search term' otherwise.
3289 SortResponse member resultCount now set to NULL in sort handler of
3292 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3295 Add three new utility functions for translating OIDs between various
3296 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3297 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3298 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3299 char *oid_to_dotstring(const int *oid, char *oidbuf);
3300 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3302 Reverted modifications for ES Update definition for z_IU0Update
3303 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3304 is back to YAZ 2.0.2.
3306 String value attributes for CCL parser.
3308 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3309 which their FirstSearch server returns in Init responses, sometimes
3310 carrying useful diagnostic information when Init fails. This has the
3311 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3312 "z39.50/oclcui.asn", where its definition is somewhat different from
3313 what OCLC document on their web-site, as required to interoperate with
3316 Support for anonymous authentication in yaz-client. Use the command
3319 * Fix the OID of the Index Data-local "admin" Extended Service from
3320 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3321 the 1000, which indicates a locally-defined OID, was a mistake.
3323 --- 2.0.3 2003/06/20
3325 Fix CCL directive @case handling so that it affects string match for
3326 both CCL keywords and qualifiers.
3328 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3329 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3330 Decoder has been updated with ASN.1 changes as listed in
3331 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3332 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3333 z_IUUpdate, remains unchanged.
3335 ZOOM_record_get may now return a record in a specific character set.
3336 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3337 "from" is the character set of record as returned by target. "to" is
3338 the character set to be returned. If omitted, "to" is UTF-8.
3340 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3342 New ODR utility, odr_getelement, which returns name of element for
3343 which encoding/decoding failed.
3345 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3346 in cases where a required element was omitted.
3348 Bug fix: some MARC8 sequences were not converted.
3350 New ZOOM option "step" which specifies number of records to be
3351 retrieved in one chunk. Used in conjunction with "start" and "count".
3353 SRW support for yaz-client. Use scheme http: to use it, e.g.
3356 yaz-client no longer does (un)intelligent character set conversions
3357 by default. Can be enabled with charset and marc_charset commands.
3359 xmalloc trace fix for 64-bit systems such as DEC alpha.
3361 Solaris 2.6 compile fix.
3363 New function, cql_strerror() translates SRW error codes, as returned
3364 by cql_transform_error(), into human-readable English strings. Used
3365 in yaz-client diagnostics when appropriate.
3367 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3368 converts it into a type-1 query which is sent to the server. This
3369 makes CQL available for use with all Z-servers, as opposed to the tiny
3370 minority that can handle CQL queries themselves.
3372 --- 2.0.2 2003/04/28
3374 New Debian package layout similar to the Redhat Package layout.
3376 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3377 and search result respectively.
3379 --- 2.0.1 2003/04/25
3381 Redhat package is now several packages: libyaz (runtime libraries),
3382 libyaz-devel (development and documentation, and yaz (utility programs).
3383 Package spec file by Morten Bogeskov.
3385 New member 'schema' in struct bend_fetch_rr which the name of requested
3386 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3387 handler MAY set this to reflect the schema of the returned record.
3389 New member 'display_term' in struct scan_entry. GFS now sets member entries
3390 and allocates scan entries to be filled by user scan handler. In previous
3391 version, entries member was allocated by the scan handler. That still works,
3392 but the GFS will ignore member display_term - assuming it was NOT set by
3393 the handler. The fact that the GFS now allocates the entries both allows
3394 for new members and makes a scan handler easier to write.
3396 Fix CQL lex buffer overflow.
3398 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3399 SRU default recordPacking is string.
3401 SRU protocol support for frontend server.
3403 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3405 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3407 Added scan for the ZOOM shell (zoomsh).
3411 * String Identifers for Schemas (Amendment 5).
3412 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3413 Old definition for schema
3414 Odr_oid *schema; /* OPT */
3419 Z_InternationalString *uri;
3420 #define Z_Schema_oid 1
3421 #define Z_Schema_uri 2
3424 * resultCount parameter to Sort Response (Amendment 1).
3425 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3427 Support for SRW 1.0 over HTTP. This is an optional feature and
3428 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3431 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3432 on the same port. SRW SearchRetrieveRequests are mapped
3433 to bend_init,bend_search,bend_fetch,bend_close.
3435 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3437 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3438 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3440 ZOOM connections are SRW based if schem http is used for hostname
3441 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3442 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3444 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3445 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3446 distance=n, order=true/false, relation=le, prox unit=word. If
3447 n is omitted, distance 1 is used.
3449 Fixed problem with C compiler include path in wrong order.
3451 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3452 on Solaris. Patch from Ko van der Sloot.
3454 New MARC decode API. All new functions operate on a yaz_marc_t
3455 handle. The most important new functions are: yaz_marc_create,
3456 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3457 decode and destroy respectively. Decoder can produce formats
3458 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3459 include/yaz/marcdisp.h.
3461 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3462 to UTF-8, UCS-32, wchar_t or Latin-1.
3464 * Prototypes for yaz_iconv_-functions moved to separate header
3465 include/yaz/yaz-iconv.h.
3467 Make a few private functions 'static' in unix.c. This prevents
3468 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3470 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3471 are set when Init Response is received.
3473 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3474 but returns diagnostic set as well.
3476 New function yaz_strerror which is a portable wrapper for
3477 strerror/strerror_r/GetLastMessage.
3479 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3480 is returned for MARC. If type is "oai", then OAI MARC is returned.
3482 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3485 --- 1.9.2 2002/11/26
3487 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3489 Fix bad race conditions on SIGTERM and terminate gracefully in
3492 Move retrieval (data1) module to Zebra since nobody seems to be
3495 Add GRS-1 render for ZOOM using same format as yaz-client.
3497 --- 1.9.1 2002/10/05
3499 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3501 Fix broken ESpec handling in data1 module.
3503 SGML reader parses comments and makes them part of the data1 tree.
3505 Added several type casts so that YAZ compiles as C++ code.
3507 ZOOM didn't handle PDU encoding failures properly.
3509 Added more Bib-1 diagnostics (approved extensions).
3511 GNU configure: better check for iconv.
3513 More portable use of accept, getpeername. Check for socklen_t. Use
3514 int/size_t if socklen_t is not defined.
3518 PQF parser rejects bad queries - including those with extra
3519 characters in them. PQF parser used to silently ignore that.
3520 Cleaner API for PQF added, which allows you to get detailed
3521 error information for bad queries (see yaz/pquery.h).
3523 Fixed bug in ZOOM_record_get for type "database".
3525 Implemented mini iconv library supporting conversions between
3526 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3528 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3530 --- 1.8.9 2002/08/20
3532 Fixed ZOOM C record cache so that preferredRecordSyntax and
3533 elementSetName is used to check for already fetched records.
3535 --- 1.8.8 2002/08/02
3537 Added three members in bend_initrequest structure to facilitate
3538 character set negotiation.
3540 Fixed a bug in frontend server that could cause indefinite
3541 loops under rare conditions.
3543 Revised character set utilities (charneg.h) so that encoding
3544 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3546 For PQF, directive @term <type> sets term type for Scan/Search.
3547 Here <type> is general, string, numeric, null. The term type
3548 is inherited - just like @attr.
3550 New call odr_set_charset that sets character set conversion for
3551 international-strings on a ODR stream. Prototype is:
3552 int odr_set_charset(ODR o, const char *to, const char *from);
3553 The InternationalString is still represented as C string in YAZ
3554 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3555 won't). On the protocol level, you can use any encoding.
3557 Support for UNIX sockets in ZOOM.
3559 Solaris recv sometimes returns errno == ENOENT. It is treated as
3560 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3562 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3563 both client and server. Code by Morten Bogeskov.
3565 --- 1.8.7 2002/05/22
3567 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3568 that they can be used directly from Visual Basic. You must recompile
3569 your windows APP if you're using ZOOM.
3571 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3572 Commands "lang" and "charset" sets language and character set respectively.
3573 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3574 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3576 Attributes from multiple CCL fields may be OR'ed rather than merged
3577 using directive "@field or". Fields are still merged by default -
3578 equivalent to "@field merge".
3580 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3583 Fixed bug in zget for parameter ExtendedServicesResponse.
3587 --- 1.8.6 2002/03/25
3589 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3591 Client displays USR.1:SearchResult-1 (hits per term).
3593 Additional Search Info for search in Generic Frontend Server.
3595 Fixed CCL parsing of "field=s".
3597 WIN32 installer - using the excellent NSIS software from nullsoft.
3599 Fixed CCL parsing of "field = - <number>".
3601 Added function yaz_marc_decode that decodes MARC for line mode
3602 display or XML (similar to that used by JZKit).
3604 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3605 Z39.50. But ISO/ILL was, however.
3607 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3608 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3610 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3611 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3613 --- 1.8.5 2002/02/03
3615 New YAZ client features: Command completion and new commands:
3616 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3617 Code provided by Jacob Poulsen.
3619 New call oid_trav, that visits all registered OIDs via callback.
3621 Function ZOOM_record_get now returns const char pointer rather than
3622 void pointer. It saves a lot of type casts.
3624 For YAZ client, command "auth" now allows you to set authentication
3625 in IdPass style. It is enabled when three tokens are given - order
3626 is user, group and password.
3628 Fix memory leaks in MARC record handling for ZOOM.
3630 New option for YAZ client, -k <kilobytes> that sets
3631 maximum record size. Similar to -k option for generic frontend
3632 server and yaz-ztest.
3634 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3636 Prefix query parser reports "fail" when bad attribute set is given.
3638 Fix in MARC decoder. Proximity logging. Fix for attribute set
3639 in scan handler for server. Patches by Shigeru Ishida.
3641 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3644 Configure option --with-openssl=<dir> now works when a directory is
3645 specified. Patch provided by Morten Bogeskov.
3647 New option for YAZ client, -u <auth>, that sets authentication.
3649 ZOOM fix: error information was sometimes "missing", since error
3650 was cleared/reset too when it shouldn't.
3652 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3654 --- 1.8.4 2002/01/04
3656 Scan for ZOOM API. New object ZOOM_scanset. New functions
3657 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3658 ZOOM_scanset_destroy.
3660 New ZOOM function, ZOOM_connection_last_event, that returns type
3661 of last event (such as "receive data", "send data", "apdu received",
3664 New ZOOM option, schema, that specifies schema for retrieval.
3666 New CCL feature. Qualifiers can be aliases for one or more
3667 other qualifiers (if more than one is given, OR is used).
3669 ZOOM uses named result sets if target supports it.
3671 Two new YAZ client commands: . (dot, which sources a script of YAZ
3672 client commands), and ! (to execute shell command.). Implemented
3675 Working on Debian packages.
3677 --- 1.8.3 2001/11/19
3679 YAZ client enables named result sets only if target supports it.
3681 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3683 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3684 with key="host" to get same result.
3686 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3687 Function Z3950_resultset_record(s) returns references to records
3688 "owned" by resultset. To become owner use Z3950_record_clone.
3690 Function z_ext_record handles Extended Services. Thanks to
3693 --- 1.8.2 2001/11/12
3695 CCL Parser fix: ignore token comma when dealing with and-lists.
3697 Documentation updates for COMSTACK.
3699 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3700 Changed prototype Z3950_records. For some functions, int parameters
3701 were changed to size_t.
3703 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3706 New MARC decode/display function, marc_display_exl, which properly rejects
3707 non-ISO2709 records. YAZ client uses it.
3709 --- 1.8.1 2001/10/29
3711 Fix bug: local attribute set wasn't set correctly in PQF strings.
3715 * Old Z39.50 codecs no longer supported.
3717 Added ZOOM C binding. See http://zoom.z3950.org/
3719 Renamed states for COMSTACKs to avoid confusion with events.
3721 Implemented cs_look and proper cs_rcvconnect.
3723 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3725 Configure detects POSIX threads on OpenBSD.
3727 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3728 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3730 When error is returned from present handler, non-surrogate diagnostic
3731 is returned in present response (and fetch handler is no longer called).
3733 * Minor adjustments to pquery parser (PQF). Token characters may be
3734 escaped by using backslash (C-style).
3736 PQF parser allows string attribute values to be specified. For @attr,
3737 non-numeric characters after the equal-sign are treated as strings
3738 (e.g. @attr 9=title).
3740 CCL trunction character may be defined (@truncation in file)
3742 * function zget_ExtendedServicesRequest sets waitAction to
3743 waitIfPossible (was wait).
3745 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3748 CCL operator names may be set in field definition files (CCL_bibset).
3749 See ccl/bib1 for an example.
3751 Fixes in ASN.1 compiler for C++ compatibility.
3753 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3754 and "op_or" to avoid conflict with C++.
3756 Fixed problem with GNU readline detection on Redhat 7.0.
3758 Added step-size for Scan backend handler.
3760 Fixed bug that made the frontend server crash when no attribute
3761 set was specified for scan.
3763 Front-end server automatically switches to original working directory
3764 when installed as an NT service. Previously -w had to be specified to
3767 Added extended attributes for retrieval module (data1), so that data1
3768 records carry d1_readXML/SGML attributes. d1_read also supports
3769 null-data rules ( <tag/>)
3771 On UNIX when POSIX threads are available, a separate library libyazthread
3772 is created. Programmers should link with that library and the yaz library
3773 when using threads. The reason for the split was that some applications
3774 on Linux, such as Apache, doesn't work well when using shared objects that
3777 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3778 (or any frontend server) in SSL mode by specifying ssl: followed by
3779 address. Only tested on UNIX.
3781 Added feature for CCL module. Virtual structure s=al or s=ol generates
3782 and-list and or-list respectively instead of phrase search.
3786 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3787 log_mask_str. This was done to avoid name conflicts with other libraries
3788 (such as other PHP extensions).
3790 Added raw OID member for preferred record syntax (request_format_raw)
3791 and returned record syntax (output_format_raw) for backend fetch method.
3793 Config file yaz-config now accepts options so that it returns specific
3794 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3796 Shared library support for UNIX using GNU libtool.
3798 * Modified backend interface. Request/Response struct's replaced by
3799 one read/write C struct. For example bend_fetchrequest and
3800 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3801 Every handler - even search has to be registered in bend_init
3802 handler. This means that the YAZ library no longer refers to
3803 external functions and it makes it possible to make the whole
3804 thing a single DLL/SO.
3806 Added Segment handler for backend server.
3808 Added Zmbol/Zebra administrative functions to YAZ client.
3810 Threaded frontend server on UNIX (when POSIX Threads are available).
3811 Starting the server with option -T enables multi-threading.
3815 Added configure option --enable-comp/disable-comp to control use
3816 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3817 located in sub directory asn.
3819 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3820 in ${exec_prefix}/bin along with the other programs yaz-client and
3823 GNU automake used to maintain makefiles.
3825 Added several OID's.
3827 Changed retrieval module so that we can load records with no abstract
3828 syntax defined. Tagpaths in these records are fully composed of string
3831 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3835 On UNIX, the generated makefile now supports a proper 'make install'.
3836 The prefix can be set via GNU configure to set the install location
3837 (default is /usr/local).
3839 * YAZ programs client and ztest were renamed to yaz-client and
3840 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3841 locations, such as /usr/bin,/usr/local/bin,etc.
3843 * YAZ Header files were moved from include to include/yaz. YAZ Header
3844 files are referred to as include <yaz/log.h> rather than <log.h>.
3845 The YAZ include path (-I ..) is therefore the same as before. Programmers
3846 should update their #include statements or use -Ipath/include/yaz
3847 instead. The main motivation for doing this change is that YAZ header files
3848 can be installed in "standard" locations /usr/include,/usr/local/include
3849 without introducing conflicts, since ALL YAZ header files are stored
3850 in subdirectory yaz (under /usr/include for example).
3852 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3853 rather than project/workspace files. We switched because project files
3854 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3857 Changed name of logging function, logf, to yaz_log, to prevent name
3858 clash with some math-log functions. The YAZ header log.h defines logf
3859 to yaz_log (#define) so there should be no incompatibilities by this
3862 Added bend_start/bend_stop handlers for server. These handler are
3863 called on start/stop of server. For windows they are called whenever
3864 a service is started/stopped.
3866 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3867 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3868 in util/yc.tcl. The auto-generated C code structures are, in a few
3869 cases, incompatible with the old decoders. There are differences in the
3870 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3871 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3872 The preprocessor variable ASN_COMPILED is defined when the compiled
3873 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3874 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3875 wish to use the old encoders/decoders you can specify --disable-yc
3878 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3879 version so that it supports both new - and old version of DB Update
3881 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3882 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3883 change. The name parameter can be set to 0 in which no name is specified
3884 for the construction. The macros odr_implicit and odr_explicit sets name
3885 parameter to zero for the construction involved. New macros
3886 odr_implicit_tag and odr_explicit_tag are similar to the others,
3887 except that a name parameter is added. For programmers' that don't use
3888 ODR they probably only need to change the call to z_APDU and z_External.
3890 Added access control facility by interfacing the TCP wrapper library.
3891 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3892 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3893 name of the daemon and enables the access control as specified in
3894 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3896 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3897 den Dool <H.M.vdnDool@kub.nl>.
3899 Added reference ID parameter to most functions in server API - refer
3900 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3902 Changed name of ccl library to libccl.a (was ccl.a).
3904 Fixed bug in decoder for Explain (Category TargetInfo).
3906 Added support for GNU readline in client. Thanks to Jacob Poulsen
3907 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3909 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3910 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3911 IMPLEMENTATION! This change was made to the development version before
3912 the ZIG decided to retract the amendment. If any users MUST be
3913 compatible with the original Update definition, PLEASE CONTACT US, and
3914 we will include a separate definition corresponding to the old Update
3915 ES. Note that because of the change to the ASN.1 of the
3916 TaskPackageRecordStructure we cannot define a single structure that
3917 will support both versions.
3919 * Added const modifier to buffer parameter for some ODR/BER encoding
3920 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3921 completeWAIS, odr_dumpBER.
3923 Fixed bug in client.c which caused a crash when a scanResponse didn't
3924 contain positionOfTerm.
3926 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3927 * will cause an error in a client if a non-YAZ target sends both a
3928 * list of Scan entries and non-surrogate diagnostics.
3930 Retrieval module enhancements. Tag sets may be typed in the reference
3931 to it. From the .abs-file the "tagset" directive takes a third optional
3932 integer type for the tag set referenced. From a .tag-file the "include"
3933 directive takes a third optional type as well. The old "type" directive
3934 in the tag set itself is still recognized but acts as the default type
3937 Backend interface change. Individual Scan terms returned from bend_scan
3938 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3939 in include/backend.h.
3941 Retrieval module enhancements. Multiple tag sets and attribute sets may
3942 be specified in abstract syntax specs. Revised the error/warning for
3943 logging messages reported by the retrieval module when reading the
3946 Object Identifier system (oid_..) changed. The API is backwards
3947 compatible but the oid-routines now allocates new OID's when needed.
3948 Raw OID's may be specified in oid_getvalbyname.
3950 YAZ now uses GNU configure to generate Makefile(s).
3952 * Minor changes in some of the member names of DeleteResultSetRequest and
3953 DeleteResultSetResponse. See include/proto.h.
3955 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3956 and added member 'languages' in TargetInfo (which was missing).
3958 Changed the way attribute sets are handled in the retrieval
3959 module. These are now cached, just like the abstract syntaxes
3962 Changed YAZ so that it links with compiled ASN.1.
3964 Added Explain-schema definitions and mapping routines. The following
3965 Explain categories have been implemented: AttributeDetails,
3966 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3968 Fixed minor bug in Windows version of Server Library.
3970 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3972 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3974 Added EXTERNAL: UNIverse Resource Report (non-standard).
3976 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3977 ENUMERATED and SET OF.
3979 * Added 'const' to some of the char pointer arguments for the
3980 functions, data1_read_node, data1_getelementbytagname,
3981 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3984 Fixed bug in data1_insert_taggeddata - the last_child member of
3985 parent wasn't initialised.
3987 * Changed data1_read_record and data1_read_node so that the supplied
3988 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3989 doesn't refer to any parts of the "SGML"-buffer.
3991 Fixed bug in server library (Windows version of statserv_remove).
3993 * Changed code so that it compiles as C++. The type definition
3994 of Odr_fun which is a member of Odr_arm was changed. The result is,
3995 that an explicit typecast is needed for the fun pointer when
3996 using Odr_arm - as in:
3997 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3999 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
4001 Implemented the new structured date and time definition as approved
4002 by the ZIG. Added schemaId element to the specificTag in Espec-1
4003 (also approved at the last ZIG). Thanks to RVDM.
4005 Added some Object identifiers (RVDM).
4007 Changed the Update Extended Service (RVDM).
4009 Added command "refid" to client which specifies referenceId for
4010 the following requests.
4012 Implemented extended service handling for server. See ztest.c
4013 for an example as well as backend.h. New handlers are registerd
4014 in the Init handler.
4016 * Changed interface for sort in server.
4018 Added new members to statserv_options_block. It allows a server
4019 to read options from another source than just the command line. Thanks
4020 to Charles Woodfield.
4022 * Changed definition of Z_Triple in file prt-grs.h - member boolean
4023 renamed to zboolean. Some C++ compilers complained about the name.
4025 Minor changes to gils.abs. Added index 's' (sort) on title
4026 and date/time-last-modified.
4028 --- 1.4pl2 1998/1/30
4030 Fixed bug in server library regarding inetd mode (-i). This bug
4031 was introduced by release 1.4.
4033 --- 1.4pl1 1998/1/29
4035 Added sort facility in client and backend server interface.
4037 Fixed problem with dependencies in Makefile(s).
4039 Fixed bugs for encoders/decoders of extended services and
4042 Implemented sub-tree feature for schemas. Sub-trees are
4043 referenced in *.abs-files. See explain.abs for an example
4044 of the use of this feature.
4046 Modified bib1.att; local attributes for ANY didn't include
4047 ANY itself (only affects use of the retrieval module).
4049 Fixed bug in plain SGML reader in function data1_read_node:
4050 tags with prefix "var" was incorrectly interpreted as variants.
4052 Added feature "sub-schemas" to enable references to - and definitions
4053 of - group of elements.
4055 * Removed member parent from type data1_element (in data1.h).
4057 Implemented function odr_nullval() that returns the value of
4060 * Removed member num_children from data1_node (in data1.h).
4062 Made NT service interface part of the server library. The
4063 function statserv_main uses the NT service when required and
4064 calls the statserv_start / statserv_close routines.
4066 Routine zget_SearchRequest and zget_PresentRequest fills
4067 resultSetName/Id member with "default" instead of "Default".
4069 Fixed memory leak in server. Request queue member wasn't freed.
4071 Fixed nmem_exit so that memory is freed.
4075 Revised the CCL parser utility to be thread safe.
4077 Added function, oid_ent_to_oid, to replace the function
4078 oid_getoidbyent, which is not thread safe.
4080 * Added nmem_init and nmem_exit to initialize and release
4081 NMEM resources. Function nmem_init should be called once in the
4082 initial thread before NMEM/ODR is used. statserv.c and client.c
4083 have been changed accordingly. The change was necessary to make
4084 NMEM thread safe. The NMEM memory pool is shared amongst threads
4085 in a process. Unix-based applications will still work fine without
4088 Added NT Services interface for the the Z39.50 (statserv) Server.
4089 Refer to the ztest.c source on the usage.
4091 Windows 95/NT port using MSVC5.0. Project files are included in the
4094 * Defined new 'global' handle for the retrieval (data1) system. The
4095 new handled, data1_handle, describes the state of the data1 system.
4096 This handle is passed as first argument to virtually all
4097 data1 related routines. The functions data1_create and data1_destroy
4098 creates and destroys a data1 handle respectively.
4100 Added ODR encode stream member to all backend request structures
4101 init, search, scan etc. This stream should be used to allocate all
4102 memory used for the response when thread safe operation is needed.
4104 Changed the comstack utility, cs_addstr, to be thread safe. The
4105 returned hostname string returned by the function is now part the
4108 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4109 function. The cs_straddr takes a COMSTACK handle as argument, so this
4110 function must be used after cs_create and before bind/connect.
4111 This function is thread safe.
4113 Moved test server to 'ztest' directory - generic server code still
4114 in 'server' directory.
4116 Made prefix query (pquery.c) utility thread safe.
4118 Added new function modifier YAZ_EXPORT to 'export' public DLL
4119 functions when using windows (see include/yconfig.h).
4121 Added definitions to the OID database (util/oid.c) (RVDM).
4123 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4125 Added call to ccl_rpn_delete in client program.
4127 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4128 release of RPN structure.
4130 Added support for C++, headers uses extern "C" for public definitions.
4131 With input from RVDM.
4133 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4134 Thanks to Ronald van der Meer (RVDM).
4136 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4138 Added support for private extensions to the OID database
4139 (oid_setprivateoids()). Thanks to RVDM.
4141 Added optional, physical ANY (key replication)
4143 Fixed null-reference problem in GRS-1 output filter.
4145 Proximity operator added to Prefix Query Format (PQF).
4147 In test client command "base" accepts multiple databases.
4149 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4153 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4155 Smallish bug-fixes in the new encoders/decoders (explain).
4157 Bug fixed in DeleteRequest.
4159 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4161 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4163 Added SOIF syntax (using private OID for now) to retrieval module and client.
4165 Added Update extended service.
4167 Added SearchResult-1 additional info structure.
4169 Added optional CCL (ISO8777) interpreter as separate module. Available
4172 --- 1.2 1996/6/10 (1st anniversary release)
4174 Added Summary record syntax. Lightly tested.
4176 Added OPAC record syntax. Untested.
4178 Added ResourceReport service encoders/decoders. Untested.
4180 Fixed bug in z_Unit - wrong tagging on unitSystem.
4182 Fixed bug in the DiagRecs decoder.
4184 Added options for max PDU size and session timeout to frontend-server.
4186 Added documentation of query-language parsers and other supporting utilities.
4188 [frontend-server] Added Attribute set to the bend_scanrequest API.
4190 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4191 surrogate diagnostics were generated.
4193 [retrieval] Allow multiple local values for attribute.
4195 [retrieval] Allow multiple attributes per element in .abs files. index type.
4197 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4199 --- 1.1pl2 1996/4/10
4201 Minor changes, mostly specific to Zebra's requirements (retrieval)
4205 Repaired bug in frontend server when running multiple listening
4206 endpoints in dynamic mode.
4208 z_External() now won't break if a known, ASN.1 value comes encapsulated
4209 in an octet-string. The value will pass through unmodified in an Odr_oct.
4211 Added a bit of code to the demo client to decode & display
4212 ASN.1-structured records represented in the octet-aligned branch of
4213 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4215 Added z_ext_getentbyref() to the ASN module. Doc updated.
4217 * Completed the SCAN definition in the ASN module. This may break SCAN
4218 code based on older YAZ-versions at compile-time. The fix is easy -
4221 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4222 under the SCAN definition. Remember to initialize this, server-people.
4224 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4225 that this does not extend to ODR and ASN.
4227 Comstack allows insertion of established socket (primarily for
4228 inetd-operation of servers). Doc updated.
4230 Front-end server can now start from the inetd in TCP mode. Doc
4233 --- 1.0pl4 1996/1/24
4237 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4238 the rank and record number.
4240 Adjustments to the frontend server.
4242 Fixed diagnostic BER dumper. It ignored the file argument.
4246 Various changes to retrieval module.
4248 Changed the union discriminators of the protocol files from enums to
4249 ints paired with #defines.
4251 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4254 *Changed operator in the RPN structure to 'roperator', again to avoid a
4257 Fixed problems in Explain decoders/encoders.
4259 --- 1.0pl2 1995/12/6
4261 Memory bug in log module fixed.
4263 --- 1.0pl1 1995/12/5
4265 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4267 Bug in Explain DatabaseInfo module fixed.
4269 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4273 The shift to v1.0 signals that we now consider the *core* functionality
4274 of YAZ reasonably stable (the core being more or less equivalent to
4275 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4276 tested (Explain not at all - though that will happen soonish).
4278 Minor changes to code to support Windows port.
4280 Various minor changes after we're getting to use GRS-1 & co. more.
4282 Added Espec-1 format.
4284 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4285 of the protocol and it cannot be selected when encoding (maps into 'string'
4286 when decoding). Needed to talk to some servers.
4288 Demo client can request simple element set names.
4290 Added Diagnostic Format encoders/decoders.
4292 Added simple Close handling to frontend server (no hooks for resource
4293 reporting yet), and demonstration client.
4295 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4297 --- 1.0b3 1995/08/24
4299 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4300 handled incorrectly when records were requested in the searchResponse. This
4301 will only affect you if you use the frontend-server.
4303 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4304 Test-client will ask for and print GRS1. Ztest will return dummy records
4307 Added Explain encoders/decoders to the service-level API. Untested.
4309 Added Extended Services: Item Order encoders and decoders to the Service-
4310 level API. Untested. We could use a recent copy of the pertinent bits
4311 of the ILL protocol to add those bits.
4313 Added diagnostic format 1 encoders/decoders to the service-level API.
4316 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4317 odr_cons.c, which causes a more correct output.
4319 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4320 was always set to 0 when no records were requested in the searchRequest.
4322 * Added better external-handling. This shouldn't harm old code that
4323 *encodes* externals. It can break code that looks for a
4324 'single-ASN1-type' representation, since those types that are known
4325 are now decoded immediately. Look at the SUTRS sample code in
4326 seshigh.c and client.c. Documentation updated.
4328 Handling of structured records in bend_fetchresponse. Length -1 marks
4329 structured record, type is deduced from format field.
4331 --- 1.0b2 1995/06/27
4332 Fairly quick maintenance release to add SUTRS support.
4334 Fixed handling of SUTRS records in the demonstration client.
4336 * Added format field to the bend_fetchrequest and bend_fetchresponce
4337 structures of the backend API (frontend server). When the record is
4338 returned, the value of the format field is mapped to an OID. The
4339 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4340 of the record. The special value VAL_NONE in the bend_request means
4341 that no specific format was requested by the client. Documentation
4342 updated accordingly. Test server (ztest) will return a fixed dummy
4343 SUTRS record if your client requests SUTRS.
4345 Documentation updated accordingly.
4347 You can now set external libraries and RANLIB support in the top-level
4351 First public release.
