3 Extended comstack with outgoing IP YAZ-795.
4 For cs_create_host + cs_create_host_proxy the vhost may be followed
5 by a outgoing host/IP. Separator is blank.
9 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
10 linker error with yazpp on Windows.
14 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
16 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
18 0 ptr reference in handling Solr response with error YAZ-791
20 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
22 Fix documentation about --installa option YAZ-788
26 daemon: properly report when receiving SIGUSR2 from child YAZ-785
30 xmalloc: throw assert for clearly invalid calls to malloc and
31 improve diagnostics YAZ-783 YAZ-784
35 Stop building debs for Ubuntu raring, quantal, oneiric.
37 CCL YAZ-781: for multiple use attributes in a specification the
38 generated RPN will perform @or on each term.
39 For spec: term u=31 u=1016
40 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
42 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
44 CCL YAZ-779: combo qualifier should allow for forward references
46 Fix buildconf.sh, automake too old on centos5 YAZ-778
47 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
48 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
49 accepts it without a warning.
53 GFS: client_query_charset conversion YAZ-777
54 This is a feature for Z39.50 clients that sends queries that are not
55 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
56 encoding given to UTF-8.
58 Echoed SRU arguments support YAZ-776
59 This is achieved with new function yaz_srw_get_pdu_e.
61 ZOOM: expire times set for redis/memcached YAZ-772
62 For both redis and memcached option --expire=seconds sets expire
63 time for a result-set/search. Default time is 600 seconds (10 minutes).
67 No [rest of output is omitted] limit for yaz_log YAZ-774
69 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
71 For ICU testing, pass -o to yaz-icu. This will test the
72 icu_iter_get_org_info function.
74 Fix null ptr reference for freeReplyObject YAZ-773
78 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
80 RPM: do not build with libmemcached support. The libmemcached library
81 on CentOS 5/6 does not work reliably for us (redis to the rescue).
83 configure: only allow libmemcached version 0.40 or later. That's the version
84 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
85 that's not an option, consider redis.
89 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
91 Fix zoom+memcached: present request out of range YAZ-767
95 CCL: add new qualifier r=omiteq which will omit relation=equals
96 for ordered relations. This should be used in combination with either
99 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
101 Solr: simplify yaz_solr_decode_response
103 Solr: use different local var for string manipulation
105 Solr: Get rid of hardcoded limit of extra_args
107 Solr: encode lucene query type YAZ-736
108 Make sure the queries are treated as traditional "lucene", because that's
111 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
115 Build packages for Ubuntu Trusty Tahr 14.04 LTS
117 wrbuf_cstr: fix off by one error.
119 wrbuf_buf: make it always return non-NULL
120 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
124 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
126 zoomsh: offer option -a apdulog
127 As we're used to from yaz-client and GFS based servers.
129 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
130 existing setting apdulog takes effect.
132 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
137 Add re-entrant CQL/Solr/RPN query conversion functions.
138 The re-entrant functions are: cql_transform_r,
139 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
140 These have same functionality as cql_transform,
141 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
142 return the additional infomration as WRBUF to make them re-entrant.
144 Remove CQL to Solr conversion and base solr_transform_t on
145 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
146 data structure as cql_transform_t.
148 cql2pqf utility allows RPN to Solr conversion
150 Fix assert in ZOOM when http connect fails YAZ-757
152 --- 5.0.22 2014/04/09
154 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
156 wrbuf_cstr: make it thread safe YAZ-753
158 yaz_log_init_file may take fd=<no> to open log file at the FD given.
160 --- 5.0.21 2014/03/21
162 Offer new utility function zget_AttributeList_use_string.
164 New conversion step, solrmarc, for record conversion module.
166 --- 5.0.20 2014/03/13
168 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
169 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
172 --- 5.0.19 2014/03/10
174 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
175 The standalone ZOOM sort was completely broken since 5.0.13.
177 ZOOM: generate event Connect rather than None for partial connect
178 (in fact getaddrinfo resolving).
180 ZOOM: only supply clientIP for InitRequest. Rather than for all
183 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
185 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
186 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
187 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
189 New "Facets" section in the documentation.
191 --- 5.0.18 2014/02/27
193 Call exsltRegisterAll in yaz_init_globals, so that all applications
194 using YAZ will have EXSLT things enabled.
196 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
198 Update various URLs to the re-organized SRU pages at LoC.
200 --- 5.0.17 2014/02/26
202 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
203 introduced in 5.0.12.
205 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
206 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
207 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
210 --- 5.0.16 2014/02/25
212 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
214 --- 5.0.15 2014/02/24
216 Fix gcrypt not properly initialized YAZ-740.
218 --- 5.0.14 2014/02/19
220 Describe memcached option for ZOOM.
222 ZOOM: throw present request out of range again YAZ-739
223 Was removed in YAZ 5.0.13.
225 --- 5.0.13 2014/02/18
227 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
228 with localtime_r when threads + fork is used (such as Metaproxy).
230 yaz-config: quote some RHS values (that might include blanks)
232 zoomsh: shows SearchResult-1
234 zoomsh: sortby command
236 zoomsh: use proper list of connections and result sets YAZ-725
238 Avoid yaz_log in sigterm handler for GFS YAZ-737
239 Logging is still performed, but outside sig handler.
241 New ZOOM C feature: result-set caching with memcached. Example:
242 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
244 Remove SSL via OpenSSL support YAZ-732
245 Also deprecate two functions from comstack that aren't working with
246 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
248 Revert "Bison: use %name-prefix directive rather than -p option"
250 --- 5.0.12 2014/01/22
252 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
254 SRU GET/Solr base URLs may hold additional ?args YAZ-729
255 ZOOM option extraArgs already does this, though. It seems useful
256 when dealing with Solr targets to limit by filter, eg.
257 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
259 Remove #fragment for HTTP request encoding YAZ-730
261 Doc: Update list of DLLs/LIBs
263 Doc: update href link to Unix utils and Git.
265 --- 5.0.11 2014/01/15
267 ZOOM: fix "lost connection" problem with servers that uses both squid
268 and another proxy behind it that returns Location headers with relative
271 zoomsh: do not use readline for stdin (no tty) YAZ-724
272 Just use fgets in that case. If the user hits Ctrl-D a new-line
275 zoomsh: empty command ignored YAZ-723
276 rather than performing exit of zoomsh.
278 yaz-url utility offers option -v to enable verbose mode.
280 yaz_url uses yaz_check_location and offers verbose mode.
282 Add new function yaz_check_location.
283 This function gets an absolute URI from Location (HTTP redirect).
285 cookie API: introduce yaz_cookies_reset
287 Update cql.y for newer bison YAZ-720
288 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
289 longer supported. Instead one must use %lex-param and %parse-param .
291 --- 5.0.10 2014/01/09
293 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
296 rpn2solr: support truncation left(2), left&right(3) YAZ-718
298 Mention SRU version 2.0 in yaz-client man page.
302 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
307 Make cs_parse_host public.A
309 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
310 introduced in YAZ 5.0.6.
314 Fix buffer corruption for yaz-ztest record fetch.
318 Allow yaz-ztest to return user-defined records (one record per file).
319 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
321 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
322 Use the stream write instead of odr_printf which has a 4K tmp buffer.
324 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
328 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
329 can read and write this format. For record format JSON, yaz-ztest returns
330 MARC-in-JSON records.
332 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
333 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
337 Improve error reporting for ICU chains YAZ-707
338 Report config element+rule when ICU status is "failure".
340 ZOOM: stop fetching if present response has no records YAZ-710
341 Some targets return less records than their hit count would suggest.
342 This prevents ZOOM from continuing to fetch records if any present
343 response has 0 records in the response.
345 Ensure that GFS calls exit if any listener fails YAZ-710
346 Before, if XML config was in use, it would start the default
351 yaz-ztest: -V shows version (like yaz-client -V)
353 New iconv encoding: danmarc YAZ-692
355 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
357 daemon: only wait for immediate child rather than all children. YAZ-704
359 yaz-client: fix setting of SRU record schema. If scheme was unset, it
360 could lead to invalid memory reference.
364 yaz-ztest returns schema for MARCXML test records. SRU require that
365 recordSchema for records.
367 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
368 instead of non-surrogate diagnostic. This is a per-record failure.
370 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
371 may refer to multiple listeners now. Attribute listenref is a comma separated
374 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
375 option is given for GFS, the dirname of filename (for -f) is used
376 as prefix for options such as cql2rpn, ccl2rpn, etc.
378 Content-Type charset fixes YAZ-701 . Do not inspect charset in
379 Content-Type header for SOAP when decoding SRU. The payload (XML)
380 itself tells what encoding it is. In response, never supply encoding
381 in Content-Type. The response payload (XML) tells what it is (with no
382 encoding in XML it's UTF-8).
384 HTTP decoding: allow blanks in URL paths YAZ-700
388 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
389 and facets. Ensure recordData and recordSchema are always present in
390 record element, because they are required.
392 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
395 Simplify in a lot of places using odr_strdupn.
397 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
401 Increase various buffers in GFS's statserv_options_block
402 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
403 This change makes many type-casts redundant, and, thus simplifies code.
405 Remove last bits of WAIS support.
407 Remove member 'size' from Odr_oct.
409 Slim down the public part of 'struct odr'. Most elements are not part
410 of struct Odr_private.
412 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
413 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
414 In particular facets are supported in both client - and server side.
415 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
416 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
417 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
418 both request/response). This is what a search handler in the GFS
419 will see (regardless of whether operating in SRU mode or Z39.50).
421 Changes to the srw.h (SRU/Solr) definitions include:
422 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
423 (char*), which replace union query and query_type (int). This is because
424 SRU 2.0 supports a queryType parameter. This also means that, to carry
425 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
426 x-pquery=PQFstring (extention parameter). The extension parameter
428 - New element, packing, that has information about SRU
429 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
431 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
433 New element, packing, in Z_SRW_explainRequest.
435 New elements in Z_SRW_scanRequest, queryType and scanClause.
436 These replace query_type and scanClase untion. This is similar to what
439 --- 4.2.69 2013/10/01
441 GFS: log when closing down - at least SIGTERM YAZ-684
442 Also change formatting WRT PID logging a bit.
444 Improve display of MARC records with multi-byte subfield IDs YAZ-695
445 In some rare cases subfield identifiers are multi-byte characters.
446 This will try to deterime length of those and split accordingly.
447 This affects display in line mode as MARCXML/MarcXchange. The encoding
448 of ISO2709 is the same.
450 Change inp argument to const for yaz_read_UTF8_char.
452 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
454 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
456 Better check of marc leader info YAZ-691
457 Problem is that some systems generate MARCXML/MarcXchange with
458 funny headers. These will not work if encoded as ISO2709.
459 Some tests produce new output, due to updated warning messages
461 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
463 yaz-client: display MAB records YAZ-689.
464 Thanks for Heiko Jansen for this patch.
466 New utility z_get_HTTP_Response_server which allows both HTTP server name
467 and HTTP server URL to be given in response.
469 Debian: do not depend on obs tcl8.3.
471 Debian: do not depend on obs libicu36-dev.
473 --- 4.2.68 2013/09/23
475 GFS: pass additionalSearchInfo to search memeber search_input if
476 given. Otherwise pass otherInfo. Request for facets and other search
477 related things will be passed there in future versions of YAZ.
479 New ZOOM setting, authenticationMode, which allows authentication
480 paramters to be encoded in the URL rather than via HTTP Basic auth.
483 rpn2solr: fix nested AND/OR handling. YAZ-685
485 Add comparison routines for some Z-types, such as NamePlusRecord,
486 RPNQuery, Query, RecordComposition and OtherInformation.
488 --- 4.2.67 2013/09/19
490 Don't decode MAB as MARC. Just like we don't attempt to decode
491 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
493 CCL: allow quoted terms for date ranges. YAZ-681
495 Introduce ccl_parser_qual_search. This function makes old function
496 ccl_qual_search, from YAZ 2, available again.
498 Add yaz_facet_list_to_wrbuf. YAZ-683
500 --- 4.2.66 2013/09/11
502 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
503 schema was given for search. YAZ-675
505 Add Solr date range searches. YAZ-621
507 --- 4.2.65 2013/08/22
509 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
511 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
513 ISO2709/MARC parse most octet aligned records; not just those that
514 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
515 MARC parse more records instead of just dumping as is. YAZ-670
517 ZOOM: proper caching for variations of record schema. YAZ-671
519 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
521 --- 4.2.63 2013/07/17
525 --- 4.2.62 2013/07/11
527 New utility z_get_HTTP_Response_details - an extended version of
530 New utility yaz_url_get_error which returns error message of last
531 failed yaz_url_exec call.
533 yaz-url and url functions: allow max HTTP redirects to be controlled.
535 New functions yaz_file_glob2, yaz_xml_include_glob.
536 These functions takes a flags parameter, which, for now only controls
537 whether to fail inclusion of a non-existing file (without glob
538 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
540 --- 4.2.61 2013/06/20
542 For MARC XML parsing, allow record without leader. A fake/default leader
543 is inserted and a warning is tagged with the record.
545 ICU: fix leak in in icu_iter_get_org_info.
547 --- 4.2.60 2013/06/14
549 ICU: fix bug in icu_iter_get_org_info (un-init variable).
551 --- 4.2.59 2013/06/11
553 Implement z_HTTP_header_remove.
555 --- 4.2.58 2013/06/11
557 ICU: Disallow 0 ptrs for some ICU string utilities.
559 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
560 returns original tokens (before normalization).
562 CCL: avoid z39.58/regex truncation when not needed. Apply only the
563 conversion of those masks, when absolutely necessary.
565 CCL: configurable masking character - @mask. Default masking character
568 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
569 full response anyway, so a Transfer-Encoding header will obstruct the
572 --- 4.2.57 2013/05/15
574 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
575 picking a socket. Problem is that some systems has IPV6 support, but
576 we can't create sockets for them, so we pick AF_UNSPEC first.
578 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
579 use content_len to determine resulting Content-Length in HTTP response
580 and NOT Content-Length supplied in headers by user.
582 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
583 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
585 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
588 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
589 with big endian and unsigned char (by default).
591 --- 4.2.56 2013/04/26
593 Fix yaz-client connect (crash in 4.2.55).
595 --- 4.2.55 2013/04/26
597 Fix proxy/host problem for ZOOM that could occur if unix sockets
600 New Debian package libyaz4-dbg.
602 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
603 differently in tcpip_close.
605 --- 4.2.54 2013/04/17
607 Windows installer of YAZ includes YAZ4J as a component.
609 CQL: allow "extra terms" again, by default. Thus, the CQL parser
610 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
611 and earlier. CQL parser may operate in strict mode where queries
612 not conforming to the standard BNF are rejected (syntax error).
613 Whether the CQL parser operates in strict mode is controlled with
614 cql_parser_strict . Strict mode enabled with option -S for utilities
615 cql2pqf and cql2xcql .
617 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
619 --- 4.2.53 2013/04/10
621 New charset, MARC-8c, which is like MARC-8 but allows control characters
622 0x01 through 0x1F, except ESC to be passed through verbatim.
624 Fix a problem with duplicate sub field character in MARC output. Problem
625 happened only when output was MARC-8 encoded.
627 --- 4.2.52 2013/04/03
629 yaz-ztest: Use hash for fake hit count. Before, random number was used.
630 This is problematic for unit tests using yaz-ztest. This patch also makes
631 a hash for CQL queries. For RPN, any term with a leading digit will be
632 treated as pseudu hit count (to force any particular hit count by a client).
634 yaz-ztest: return unique MARC dummy records. Beyond record offset
635 24, the author surname is patched with offset to make all records
638 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
639 on system wide default (/proc/sys/net/ipv6/bindv6only).
640 @4 binds to IPV4 only. @6 binds to IPV6 only.
642 Update CQL API documentation a bit
644 CQL: don't accept extra terms for queries. Makes the CQL parser
645 stricly conformant to the standard.
647 --- 4.2.51 2013/02/12
649 GFS: scan handler gets extra_args from request and may return extra
650 response data . That's for SRU only.
652 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
654 --- 4.2.50 2013/01/30
656 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
658 OPACXML: sync spelling of availabilityDate in XML to that of Schema
659 opaxxml.xsd. The schema had the correct spelling of this member always.
660 The ASN.1 was mis-spelled and still is (API change) - we are
661 not changing this. However, the OPAC to XML conversion had yet
664 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
667 New function, z_ext_record_oid_nmem, which is similar to
668 z_ext_record_oid but takes NMEM rather than ODR
670 --- 4.2.49 2013/01/18
672 ICU: New conversion element 'join' which joins tokens into one
673 with a custom character given by rule attribute.
675 --- 4.2.48 2013/01/10
677 New GFS search member: present_number. This is a hint to the
678 search handler how many records are going to be fetched immediately
679 following search. There's no guarantee that it's going to be the case,
680 since it depends on hit count (for Z39.50 piggyback) and whether errors
683 Make a few functions static (private). The functions getbyte_stream,
684 ungetbyte_stream and yaz_gets are now private. They were never declared
687 yaz-marcdump: exit(5) for serious decoding errors
689 ISO2709 decoding: be more picky WRT header
691 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
692 was only used as to indicate that next-result-set-position should be
694 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
695 Based on patch from Ashley Sanders.
697 Make some functions static/private in PQF parsing. Those functions were
698 never declared in a public header and so should not be in use by
699 applications based on YAZ.
701 --- 4.2.47 2012/11/23
703 ZOOM: special options to control APDU logging.
704 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
705 logging of APDUs until "saveAPDU" option is set again. If logging is
706 already enabled the effect is that current APDU buffer is cleared.
707 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
708 logging (default behavior on new connection).
709 The APDUs sent/received can be obtained by using
710 Using ZOOM_connection_option_get(c, "APDU") or
711 ZOOM_connection_option_getl(c, "APDU", &l).
713 GFS: relay implementation_version from backend
714 From 3.0.40 and later, implementation_version from backend was
715 not used in init response at all.
717 --- 4.2.46 2012/11/15
719 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
720 mode at all. Probably never did.
722 Make a new version of ztest.pem that, at least, is not expired.
724 --- 4.2.45 2012/11/13
726 Fix description of CCL directive 'case'.
728 More tight checking of form arguments (yaz_uri_to_array). Makes
729 YAZ better at rejecting big and/or bad POSTs.
731 SRU decoding does not report more than up to 10 invalid arguments.
733 rpn2cql: less quotes in generated terms. Semantics unchanged, but
734 it's prettier this way.
736 --- 4.2.44 2012/10/25
738 New utility yaz_decode_init_diag. Defined in proto.h.
740 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
741 given for unix local socket.
742 The COMSTACK string for doing so is:
745 unix:/myfile:tcp:localhost:9999/mybase
746 unix:/myfile:localhost:9999/mybase
747 unix:/myfile:http://fakehost/mybase
749 debian: Use dpkg-buildflags in build process.
751 --- 4.2.43 2012/10/19
753 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
754 global's SRU service uses a recordPosition scheme starting from zero.
755 First record's position should be one
756 according to the standard.
758 --- 4.2.42 2012/10/18
760 Allow more namespaces for SRU. This is to allow, for example, an
761 incorrect namespace returned from server
762 http://services.igi-global.com/sru .
764 Minor fixes for compilation on Windows.
766 --- 4.2.41 2012/10/11
768 daemon: log total number of bad signals from child on stop so that it
769 is more easy to spot problems with child worker processes.
771 retrieval: empty backend name attribute omits element set
772 from being used in retrieval.
774 --- 4.2.40 2012/10/04
776 Implement Solr sort strategy "solr", similar to sru11 sorting.
777 This will implement the correct parameters on Solr requst to do
780 --- 4.2.39 2012/09/28
782 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
785 MARC: Extra/missing indicator handled for MARCXML.
786 The indicator length is given in header and is the same for the
787 whole record. If attributes ind1, ind2 are missing, then content
788 character defaults to blank. Extra indicator attributes (beyond)
789 indicator length are treated as an error.
791 Reformat: delete trailing whitespace
793 --- 4.2.38 2012/09/17
795 MARC: fix non-ASCII characters for leader. This is to ensure we can
796 generate XML in UTF-8.
798 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
799 in one node with structure word.
801 --- 4.2.37 2012/09/04
803 yaz-json-parse: JSON output may be pretty printed by using option
806 Increase default value of max message for Z39.50 Init for GFS, ZOOM
807 and yaz-client. Old value was 1 MB. New value is 64 MB.
809 --- 4.2.36 2012/08/22
811 yaz-client: don't display bogus records from SRU servers. Some SRU servers
812 return more records than given by *maximumRecords*. Skipping those in
815 record_render: simplify buffer return handling and fix at least one bad
816 memory reference, that broke the test_embed_record sometimes.
818 Allow http://user:pass@host notation for yaz_url_exec.
820 zoomsh: allow shell command to be executed. Via the system(3) call.
822 yaz_poll: Allow num_fds == 0
824 yaz-client: fix bad encoding of "itemorder item". The itemorder
825 item <no> - command forgot to use length of encoded Item Request
826 package. Error present since YAZ 3.
828 yaz-ztest: fix bad usage of session handle. Bug was introduced when
829 result sets were saved (271a9c83).
831 SRU recordPacking: guess record packing in response rather than looking
832 at the recordPacking element which, OF COURSE, changed semantics in SRU
835 Decode SRU 2.0 responses. The official namespace for responses, according
836 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
837 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
838 nature.com's server, however, usee namespace
839 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
840 we are now using a glob-expr to match up the namespace. ZOOM C and
841 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
842 I can not find a single real example showing the "real" namespace in
843 the documentation from OASIS. The namespace for requests is different
844 from responses, but this is not added to YAZ yet, when we don't encode
847 --- 4.2.35 2012/06/26
849 zoom/record_render: add support for Base64 decoding fo MARC records
850 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
851 which will decode base64 + ISO2709 marc-8 encoded material from text node
854 --- 4.2.34 2012/06/07
856 Add missing definitions ZOOM_resultset_get_facet_field_by_index
857 and ZOOM_resultset_facets_names.
859 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
862 Change APDU dump printing to avoid long leading blanks. For levels 16
863 or larger the level is shown and the indentation is truncated but
864 recursed with modula 8. This makes it still reasonable easy to read
865 - even for nested BER dumps.
867 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
868 return 0 (incomplete package) in case where the BER package was
869 considered too nested (return value of -2).
871 dumpber: lines of level 15 are not indented further. Two spaces per
872 indentation; indentation 15 or more is indented to a fixed indentation
873 and augmented with a level=<no> indication.
875 zoomsh: increase max size of command+args
877 GFS: No limit in RPN buf size in CQL to RPN conversion.
879 --- 4.2.33 2012/05/09
881 New function for daemon utility, yaz_daemon_stop .
883 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
885 --- 4.2.32 2012/04/25
887 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
888 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
890 --- 4.2.31 2012/04/23
892 YAZ daemon utility relays SIGUSR1 to child process.
894 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
895 would result in en empty database list - which in turn would result in
896 encoding failure for search.
898 Fix reading beyond string in yaz_sort_spec.
900 --- 4.2.30 2012/04/11
902 Add two new SRU diagnostics:
903 236: Access to specified database denied
904 1015: Init/AC: Maximum number of simultaneous sessions for Userid
906 Document the very useful ZOOM-C option "apdulog".
908 CQL to RPN: term may be passed through verbatim. This is enabled with
909 truncation.cql . The assumption being that the term is already CQL.
911 --- 4.2.29 2012/03/20
913 record_conv: leader spec may be given for marc element.
914 The leader spec is given as attribute leaderspec for element marc.
915 For example to convert a MARC21 record from MARC-8 to UTF-8:
916 <marc inputformat="marc" outputformat="marc"
917 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
919 record_conv: allow user-XSLT params. For example:
920 <xslt stylesheet="MARC21slim2DC.xsl">
921 <param name="myparameter" value="myvalue"/>
922 <param name="otherparameter" value="othervalue"/>
925 record_conv: fix error handling for missing marc charsets.
927 CQL: fix extra terms in wrong order.
929 --- 4.2.28 2012/03/06
931 record_conv: modify new API for conversion types. The conversion types
932 may be passed in new functions yaz_record_conv_configure_t and
933 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
935 Avoid mixed statement/variable declare; fixes compilation with Visual
938 --- 4.2.27 2012/02/28
940 Add non-standard SRU diagnostic: 235: "Database does not exist".
941 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
942 Update SRU to Bib-1 diagnostic maps accordingly.
944 CCL: add two new diagnostics for unsupported masking. The new
945 diagnostics are: "Embedded truncation not supported" and
946 "Single charcacter mask not supported".
948 --- 4.2.26 2012/02/23
950 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
952 --- 4.2.25 2012/01/11
954 Build YAZ for Ubuntu Oneiric.
956 CCL: allow parantheses for proximity operands. For example CCL query
957 (a) % (b) is now allowed.
959 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
960 marked dead, rather then being destroyed. If not, the session memory is
961 being free'd before the search/scan handler is finished. Also destroy
962 'request' memory in request_release rather than in various places,
963 which resulted in leaks from time to time.
965 --- 4.2.24 2011/12/21
967 cql_sortby_to_sortkeys: honor sort prefix.
969 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
970 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
971 The rpn2cql family of functions now always returns quoted CQL terms.
973 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
975 --- 4.2.23 2011/12/15
977 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
978 sequence is treated as one. For example, &&a=b&&&c& is identical to
981 --- 4.2.22 2011/12/05
983 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
984 APDUs for a connection to a WRBUF.
986 --- 4.2.21 2011/11/23
988 Fix cql_sortby_to_sortkeys. Completely broken before.
990 Make CCL's @truncation work again.
992 --- 4.2.20 2011/11/09
994 New ZOOM connection setting: tproxy. It's like proxy, but does not
995 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
996 to set resolved address + port for a connection outside ZOOM itself.
998 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1000 --- 4.2.19 2011/11/07
1002 Fix uninitialized variable in Solr spell support (could cause SEGV
1003 for SRU response decoding).
1005 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1006 back-end's addinfo through into the ZOOM response addinfo.
1008 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1009 they are separated by a colon and a space rather than simply
1012 --- 4.2.18 2011/10/28
1014 Add support for Solr spell-checking/suggestions through ZOOM.
1015 If a Solr target has been configured correctly for spelling-checking
1016 and suggestions, these will now be returned on the ResultSet option
1017 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1019 --- 4.2.17 2011/09/28
1021 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1022 with a flag whether to substitute escape sequences or not.
1024 --- 4.2.16 2011/09/22
1026 Fix nmem_strsplit_escape to substitute escape char properly.
1028 New option for zoomsh -e , which makes it abort on first error and
1029 return process exit code to indicate success/failure.
1031 YAZ options utility supports special option -- which makes all it treat
1032 all following arguments as non-options.
1034 --- 4.2.15 2011/09/16
1036 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1037 searched if absolute filename is given.
1039 Fix conv_xslt() error-reporting when stylesheet is not found.
1040 (The value of fullpath is meaningless in this situation.)
1042 --- 4.2.14 2011/09/07
1044 Fix problem in CQL sort node creation: un-initialized memory.
1046 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1047 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1048 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1051 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1052 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1054 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1055 will make it possible to use both single-character mask (#) and wildcard (?)
1056 in CCL . Throw diagnostic for left truncation because that is not supported
1059 --- 4.2.13 2011/09/01
1061 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1062 cases using escapes (\-sequences) and masking.
1064 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1065 would result in a read one byte beyond string.
1067 rpn2ccl may use Z39.50 masking for terms (t=z).
1069 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1071 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1072 not --cppflags (which seeems like an error in icu-config).
1074 --- 4.2.12 2011/08/27 RPM package only
1076 cql2ccl: fix conversion of terms: operator characters were not
1079 --- 4.2.11 2011/08/25 RPM package only
1081 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1082 CCL parser will map both # and ? to their regular expression
1083 quivalents (. and .*).
1085 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1086 of reserved CQL characters.
1088 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1089 is, so that they are passed through.
1091 --- 4.2.10 2011/08/24
1093 ZOOM SRU mode: more aggressive re-connect.
1095 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1096 made available as a utility function, declared in <yaz/logrpn.h>
1098 rpn2cql_structure() supports proximity nodes (except that the Type-1
1099 proximity node's "exclusion" binary is ignored, as there is no way to
1100 express that in CQL). Fixes bug #4564.
1102 --- 4.2.9 2011/08/18
1104 Fix SEGV that could occur if set command of zoomsh was given without
1105 value (2nd argument).
1107 Fix SEGV that could occur if unsupported transport was given for
1108 COMSTACK - say https (when SSL was unavailable).
1110 Build yaz-url on Windows too.
1112 --- 4.2.8 2011/08/11
1114 New utility to get web content. Header is url.h. A command line tool
1115 yaz-url is part of the distribution and packages.
1117 Fixes for SSL COMSTACK (when gnutls is in use).
1119 New functions yaz_base64{encode,decode}. Header is base64.h.
1121 --- 4.2.7 2011/08/03
1123 ZOOM C includes HTTP response buffer as additional info if it fails
1124 to decode the SRU response.
1126 Make wrbuf_json_puts available.
1128 --- 4.2.6 2011/07/28
1130 zoom: throw diagnostic for invalid value for option "sru". Before a
1131 bad SRU request was sent.
1133 Adding new utility wrbuf_vp_puts.
1135 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1137 --- 4.2.5 2011/07/21
1139 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1140 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1141 redirect was used at the same time.
1143 MARC line mode decoding: be less picky about length given - first
1144 5 digits of header that is.
1146 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1148 Changes to decoding of SRU records: a record with recordPacking=xml is
1149 modified with a new root element <yaz_record> if the recordData contains
1150 multiple children elements. This is to make the record XML parseable
1153 RPN to Solr conversion: encode special characters.
1155 Generic Frontend Server: fix uinitialized member, stepSize.
1157 --- 4.2.4 2011/06/21
1159 Fix a bug in SRU decoding of records.. The database records stored
1160 had un-initialized memory, but it would only be seen with yaz_record_render
1161 and type_spec="ext" .
1163 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1165 --- 4.2.3 2011/06/17
1167 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1169 --- 4.2.2 2011/06/10
1171 Add new utilities to convert from CQL to CCL . These utilities have
1172 prefix cql_to_ccl defined in cql.h.
1174 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1175 lead to memory heap corruptions when ICU utilities were in use.
1177 --- 4.2.1 2011/06/07
1179 Make compilation work without Libxml2.
1181 yaz-client: remove redundant blanks in display of searchResult-1 term
1184 --- 4.2.0 2011/05/18
1186 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1187 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1189 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1190 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1191 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1192 Note that the CQL sortby spec is only converted when the GFS is already
1193 converting from CQL to RPN (cql2rpn element).
1195 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1196 specify whether to collapse delimitors or not. The existing nmem_strsplit
1197 do collapse (collapse parameter = 1).
1199 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1201 Rename internal func yaz_use_attribute_create. While non-static, this
1202 function is not declared in a public header.
1204 --- 4.1.7 2011/03/15
1206 Add -lCrun when linking with ICU on Solaris.
1208 More quicks character set conversions for OPAC records.
1210 --- 4.1.6 2011/03/10
1212 fix problem with record_render: records were converted (character set
1213 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1215 --- 4.1.5 2011/03/08
1217 SRU: add methods for handling DADS SRU-proxy facets.
1219 Separate OPAC record character set for ZOOM_record. yaz_record_render
1220 allows a character set given as charset=from/opacfrom,to where 'from' is
1221 the character set of a bibliographic record, 'opacfrom' is character set
1222 of OPAC record and 'to' is the target character set.
1224 --- 4.1.4 2011/02/21
1226 yaz-client: show may XML format records. Command show followed by 'format'
1227 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1230 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1233 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1235 --- 4.1.3 2011/01/27
1236 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1238 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1239 this package can be distinguished from other vendors.
1241 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1242 as determined by configure
1244 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1246 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1247 returns no error and no record, the present request is considered
1248 partial (only a subset of the records could be returned by backend), and
1249 so it is appropriate to set Present Status to partial-4.
1251 --- 4.1.2 2010/11/02
1253 Move yaz-config man pages to section 1.
1255 More documentation about Solr.
1257 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1258 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1259 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1260 peers on some Linux systems. However, in general that does not work
1261 so YAZ can not rely on that to work. Debian changed behavior in this
1262 respect from Debian lenny to Debian squeeze (still testing as of Oct
1264 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1266 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1268 --- 4.1.1 2010/10/05
1270 Fix yaz-config output: echo_source not set correctly by configure.
1272 --- 4.1.0 2010/10/05
1274 Solr Web Service support for yaz-client and ZOOM.
1276 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1278 --- 4.0.12 2010/08/17
1280 Z39.50 facet support. Facet specifications are passed for search in
1281 other-information with ASN.1 as defined in facet.asn and OID
1282 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1283 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1284 3 is limit (number of entries to get in response). yaz-ztest returns
1285 dummy facets if a client asks for them.
1287 --- 4.0.11 2010/07/09
1289 CCL fixes: bug 2895 and bug 3539.
1291 GR1-display: add comma in display - was removed by mistake in
1294 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1296 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1298 --- 4.0.10 2010/06/18
1300 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1301 result set from a connection. The result set will be on its own
1302 thereafter; no operations on it will perform retrievals from a target.
1303 Only cached copies are returned.
1305 ZOOM C:fix case for HTTP servers responding with Connection:close.
1306 Ensure that if there is a current task it is resumed (like fetching
1307 more records in a result set) . Bug #3484.
1309 PQF parser: use odr_atoi for Odr_int (not atoi)
1311 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1312 values that contain any non-digits are treated as string attributes
1313 (previously decoding only checked for leading character ([0-9]). PQF
1314 encoding: attribute string values are not surrounded by double-quotes.
1316 --- 4.0.9 2010/05/21
1318 New utility for managing threads - thread_create.h.
1320 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1321 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1322 but YAZ' implementation do.
1324 Fixes for yaz_cond-functions on Windows 7.
1326 DLL export more symbols.
1328 zoomsh: show record do NOT render opac.
1330 Remove *.la files from Debian and RPM packages.
1332 --- 4.0.8 2010/05/11
1334 Debian package libyaz-dev depends on libgnutls-dev again (was
1335 removed in YAZ 4.0.6, but due to Libtool it is still needed
1336 even though yaz-config do not list libgnutls libs).
1338 ZOOM: Use only one WRBUF for returning string results for
1339 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1341 ZOOM: ZOOM_connection do not use a shared pointer to
1342 ZOOM_resultset after ZOOM_resultset is destructed by
1343 user. Reverts to YAZ 4.0.4 behavior.
1345 --- 4.0.7 2010/05/04
1347 record-conv: fix problem with at least one XSL conversion -
1348 due to probably incorrect usage of XML XSL documents.
1350 --- 4.0.6 2010/04/29
1352 Fix yaz-config for static mode and the use of SSL (gnutls).
1354 --- 4.0.5 2010/04/29
1356 Forward decl timeval struct in mutex.h and gettimeofday.h.
1358 yaz-config: fix 'static' mode linking.
1360 --- 4.0.4 2010/04/28
1362 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1363 are wrappers for pthreads or Windows. For Windows these are put in
1364 a separate DLL: yaz_cond4.
1366 libyaz.la (whole source) is compiled with thread. If thread support
1367 is enabled enabled, all source of YAZ is compiled with treading support.
1368 This allows core utilities such as yaz_log to use thread facilities.
1369 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1370 thread utilities. This commit moves mutex utilities (mutex.c) from
1371 libyaz_server.la to libyaz.la.
1373 yaz-json-parse displays leading text until error.
1375 --- 4.0.3 2010/04/09
1377 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1378 patch from Giannis Kosmas.
1380 SRU: no longer URL encode SRU database. The URL for an SRU server is
1381 a URL and such is alreeady encoded - at least when given with leading
1382 http:// or https://. This reverts behavior to YAZ 3.0.50.
1384 Support for new MARC XML notation TurboMARC which like MARCXML is a
1385 complete representation of MARC/ISO2709.. This one, however, is more
1386 compact and allows for faster processing with XSLT. TurboMARC can be
1387 used in the marcdisp.h API, from the yaz-marcdump utility and from
1390 yaz-ztest can be configured - via the database - to perform certain
1391 delays when it performs operations search, present and single record
1392 fetch. This allows testers to make yaz-ztest act as a real or even slow
1393 Z39.50 server. Refer to the yaz-ztest man pages for details.
1395 --- 4.0.2 2010/03/09
1397 wrbuf_destroy allows NULL WRBUF passed to it.
1399 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1401 Add ZOOM_connection_close.
1403 No fixed size buffers for ZOOM shell - bug #3257.
1405 tstodr: make it work on s390 platform.
1407 New icu iterator-functions. The new icu_iter-functions makes it possible
1408 to use ICU chains from many threads.
1410 yaz-client: better syntax check for show command.
1412 --- 4.0.1 2010/01/26
1414 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1417 New simple local-file XML include facility which allows file glob-patterns.
1418 Refer to yaz/xml_include.h.
1420 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1423 ZOOM_record_get supports new parameter "format" which makes it format XML
1426 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1427 JSONText in ECMA-262) is JSONValue, not JSONObject.
1429 --- 4.0.0 2010/01/20
1431 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1432 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1434 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1435 POSIX/Unix builds .so with major version 4.
1437 Remove old LOG_-defines from log.h. They have been obsolete and
1438 undefined by default for the last 5 years.
1440 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1442 GFS: Remove socket (int *fd) from search_rr handler. The socket
1443 descriptor ptr is a facility that allowed a search handler to supply
1444 a socket which would serve as a callback - when search was complete.
1445 This facility has now been in use for years.
1447 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1448 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1449 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1450 returns 'const char *' rather than 'char *. The returned string is
1451 read-only and should not be modified by applications. COMSTACK cs_close is
1452 now a void function - it no longer returns int. No applications check for
1453 the value and the implementations has always returned 0.
1455 ZOOM: use size_t for scan hit counts and str size. Functions
1456 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1457 occ (hit count) and len (string length) are now of type size_t pointer
1458 rather than int pointer. This is to be able to represent large hit counts
1459 and to also just to use the proper type for string length (strlen result).
1461 New JSON parser. Refer to include/yaz/json.h .
1463 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1464 Used to be int in some cases. Many wrbuf_-functions used to return an int
1465 indicating some length.. These return values were never used. And so they
1468 ODR: odr_malloc, odr_total now takes size_t for size.
1470 clone_z_type: fix leak; occurred for encoding failures.
1472 --- 3.0.52 2009/12/03
1474 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1475 bug was introduced in 3.0.51.
1477 --- 3.0.51 2009/12/02
1479 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1481 tcpip comstack: fix leak for getaddrinfo.
1483 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1484 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1485 Decoding of SRU "path" database is performed by private function
1486 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1487 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1489 yaz-client: honor base command for SRU. Change when database setting
1490 is applied for SRU and ensure it is kept when a connection is reset.
1491 Change also the way errors are displayed or SRU (decoding of packages).
1493 --- 3.0.50 2009/11/02
1495 Add support for extra request / response data for SRU codecs and GFS.
1496 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1497 for extra data response buffer and length. For the GFS, both request
1498 and response data (XML) is carried in extra_args and extra_response_data
1499 for the search handler. Patch by Ko van der Sloot.
1501 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1502 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1503 10010). This fixes bug #2113.
1505 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1506 cmdfile included a 'quit' command that would result in a memory violation.
1508 --- 3.0.49 2009/10/01
1510 Make a number of functions defined in xmlquery.c static. These have
1511 never been declared in a public header file (yaz/xmlquery.h) and was
1512 made public by mistake.
1514 Improve speed of character conversions (iconv utilities). This makes
1515 conversions from MARC-8 faster.
1517 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1518 unless type desired is "raw". This will prevent type "xml" from
1519 returning ISO2709 .. Which obviously can not be XML parsed.
1521 Fix memory leak in ZOOM that would occur if option apdulog was used
1522 on a re-used connection.
1524 Frontend server logs HTTP requests.
1526 Frontend server now sends Z39.50 close when it times out (sesssion has
1527 been idle for too long). Versions 2.0.30 and earlier also sent close.
1528 But due to a mistake this was disabled in all versions after that, i.e.
1529 the server would just close the socket immediately.
1531 yaz-client emits a better message when receiving an unrecognised
1532 userInformationField.
1534 Skip zero-length subfields when decoding ISO2709. This rare case happens
1535 if a record has two FS characters in a sequence. Without this patch
1536 there would be a reference beyond char array in using_code_len fragments
1539 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1541 --- 3.0.48 2009/08/28
1543 The show command offered by the zoomsh command now takes a 3d optional
1544 parameter type which is what is passed to ZOOM_record. If the type
1545 argument is omitted, "render" is used.
1547 RPN to CQL conv may use USE string attributes (bug #2978).
1549 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1551 --- 3.0.47 2009/07/08
1553 Function yaz_xml2query allows a diagnostic element in the PQF XML
1554 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1555 code and additional info respectively.
1557 The BER BOOLEAN is now the integral type Odr_bool which still happens
1558 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1559 typedef'd to Odr_int. This is still an integral 'int', but it may be
1560 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1561 ASN-1 compiler as well as programs has been updated to use the new types.
1563 --- 3.0.46 2009/06/08
1565 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1566 only the bibliographic record was rendered. For type=opac, an OPAC
1567 record is only returned if it is present.
1569 iconv: small fix for encoding of advancegreek.
1571 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1573 yaz-client: option auto_reconnect=on really reconnects.
1575 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1577 server: avoid null ptr ref for for yaz_poll errors.
1579 build: fix RPM build for RHEL 5.3.
1581 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1583 --- 3.0.45 2009/03/31
1585 Fixed bug #2709: TCP connect returns Invalid argument.
1587 Fixed compilation for mingw.
1589 Honor charset for raw records (ZOOM_record_get).
1591 Fixed use of errno for threaded mode that was seen on Solaris 10.
1593 Fixed argument passing with blanks in value for Windows Service.
1595 Disable YAZ' own log rotate by default (no 1 GB limit).
1596 The variable l_max_size which specifies the log file limit is set to 0
1597 (DISABLED): This is due to the fact that YAZ is most often deployed using
1598 logrotate. Also YAZ can not perform log rotate because of unsufficient
1599 permissions (setuid).
1601 --- 3.0.44 2009/02/17
1603 List supported encodings in man page for yaz-iconv.
1605 Fixed missing SSL libs for --libs output
1607 Re-established OID record syntax application-xml. Nobody should use it
1608 but we don't want to change soname because of this symbol being absent.
1610 --- 3.0.42 2009/02/02
1612 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1614 Added member named_result_sets for init handler struct for the GFS. This
1615 allows a server to disable named result sets.
1617 Removed OID record syntax application-xml.
1619 Added support for rule-based transliterator for ICU wrapper of YAZ.
1621 Fixed bug #1902: yaz-icu XML output.
1623 Make YAZ checks Emacs friendly.
1625 BITSTRING value shows value. Bug #2346.
1627 ISO2709 decoding: skip control characters from indicator data.
1629 Omit sort key by default in yaz-icu's output.
1631 Allow combined single char options (again) for YAZ' options function.
1633 Utility yaz-marcdump got option to display YAZ version (-V).
1635 Allow YAZ to use ICU 3.4.
1637 Added new ICU test case which illustrates removal of diacritics.
1639 --- 3.0.41 2008/12/29
1641 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1643 --- 3.0.40 2008/12/29
1645 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1648 Fixed bug #2352: yaz-marcdump crashes for certain record.
1650 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1652 Added support for Danmarc2 to UTF-8 conversion.
1654 Added support for ISO5426 to UTF-8 conversion.
1656 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1657 implementation version.
1659 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1661 --- 3.0.38 2008/11/10
1663 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1664 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1666 ZOOM C now interprets databaseName option for ZOOM connection as path
1669 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1671 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1673 Dummy Libxml2 types no longer defined in headers of YAZ'.
1675 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1678 --- 3.0.36 2008/09/26
1680 Various ODR chapter fixes.
1682 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1684 Added missing source for Windows compilation, mutex.c.
1686 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1688 For SRU connections in ZOOM all records up to "count" are now fetched.
1690 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1691 in Windows due to bad error handling for Libxml2.
1693 Added facility for sending arbitrary records (ASN.1 any) using
1694 ZOOM C's Extended service update. Patch by Sam Reynolds.
1696 New options for ZOOM C's connection, logapdu which makes ZOOM log
1699 --- 3.0.34 2008/06/18
1701 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1703 --- 3.0.32 2008/06/12
1705 Fixed memory violation that could occur when decoding UTF-8. This bug
1706 was only present in 3.0.30 of YAZ.
1708 --- 3.0.30 2008/06/06
1710 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1711 GNU TLS is used by default (if found).
1713 yaz-ztest returns OPAC records if a client asks for OPAC.
1715 Improved speed of MARC-8 encoding.
1717 Added support for lossy and loss-less MARC-8 encoding.
1719 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1721 Added new Windows Service wrapper (sc).
1723 yaz-client's itemorder command may now send a file.
1725 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1727 Added new function yaz_log_xml_errors.
1729 Allow (but warn) unknown XML attributes in MARCXML parsing.
1731 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1733 The UTF-8 to MARC-8 conversion now uses a different set of characters
1734 for Greek symbols. Bug #2120.
1736 --- 3.0.26 2008/02/21
1738 Added yaz_daemon (daemon.h).
1740 Fixed bug #2068: pkg-config trouble
1742 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1744 --- 3.0.24 2008/01/28
1746 Document --with-xml2 option.
1748 Added OPAC XML XSD (etc/opacxml.xsd).
1750 Allow glob mask for name attribute in retrieval element for the
1751 generic frontend server's retrieval facility.
1753 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1754 except POLLIN/POLLOUT.
1756 Fixed error handling in cs_listen. Bug #2037.
1758 --- 3.0.22 2008/01/20
1760 Fixed version in yaz/yaz-version.h.
1762 Fixed bug #2027: Crash when closing connection.
1764 Changed configure so that ICU support is only enabled if only ICU
1765 and Libxml2 is available (because the ICU chain is XML based).
1767 --- 3.0.20 2008/01/15
1769 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1770 is built. Only this DLL depends on the ICU runtime.
1772 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1773 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1775 Changed license of CCL module to 'Revised BSD'. After consultation with
1776 remaining members of the original EUROPAGATE consortium, we are re-issuing
1777 the CCL module without a separate license. The software was developed by
1778 Index Data as part of a research project. The special license was included
1779 to help feed usage information back to the project consortium to support
1780 project evaluation. At this time, the project consortium has long-since
1781 disbanded, and the majority of the original principals have retired. At the
1782 same time, we have significantly modified the software during the following
1783 years, to the point where very practically no original code remains. To
1784 simplify re-use of the software, we have contacted those members of the
1785 consortium who could be reached, and agreed to re-issue the module as a
1786 proper part of the YAZ package.
1788 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1790 CQL closer to being version 1.2 compliant. CQL also allows free-form
1791 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1794 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1795 bug could make Extended services handling crash in the ZOOM layer. This
1796 bug was only present in YAZ 3.0.18.
1798 --- 3.0.18 2007/12/19
1800 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1803 yaz-marcdump reads and writes collection wrapped records.
1805 Handle OPAC for record conversion module.
1807 Fixes for ICU wrapper.
1809 Allow ICU libs to be controlled with --with-icu .
1811 --- 3.0.16 2007/11/12
1813 Added yaz_poll which is a wrapper for select/poll. When poll is available
1814 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1815 sockets to be in use.
1817 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1818 functionality through an XML based configuration (ICU chain). This system
1819 is useful for search facilities such as Pazpar2 and Zebra that needs to
1820 perform tokenization of indexed material. The ICU code in a separate
1821 library libyaz3_icu.a.
1823 Added HTTP tunnel facility for COMSTACK, bug #1752.
1824 This is a facility that allows a Web proxy, such as squid, to tunnel
1825 Z39.50 traffic. This facility is "transparent" to must applications
1826 using YAZ. It's enabled by using pseudo transport connect: followed by
1827 the proxy address, followed by command, then follwed by he regular
1828 "virtual" addresss. For example,
1829 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1831 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1833 --- 3.0.14 2007/09/21
1835 Fixed bad memory reference in ZOOM_record - cuased by member not being
1836 initialized. This was a problem only in YAZ 3.0.12.
1838 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1839 fields were not removed.
1841 Changed the way C code is generated from codetables.xml. Made a MARC-8
1842 conversion trie for each characterSet section rather than codeTable.
1843 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1844 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1846 --- 3.0.12 2007/09/12
1848 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1849 from ZOOM_record_error).
1851 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1853 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1855 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1857 Better SRW-to-Bib-1 diagnostic mapping.
1859 ZOOM C and yaz-client announces SRU version 1.2 by default.
1861 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1864 Fixed in yaz_sru_decode to allow other version than 1.1.
1866 --- 3.0.10 2007/08/22
1868 Added support for SRU scan for ZOOM.
1870 Added support for the use of the older versions or Extended Service
1871 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1872 set to the version , 1=first, 2=second, 3=third. The third version is
1873 what ZOOM C has used so far. And that, obviously, is the default.
1875 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1876 therefore in Zebra and in SimpleServer-based applications). The new
1877 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1878 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1879 which is passed into the back-end search callback function.
1881 Added support for HTTP Basic authentication in clients: the SRU/W
1882 codec encodes the username/password elements of the PDU structure
1883 appropriately, and these may be set using the "user" and "password"
1884 options in ZOOM-C applications (the same options that are used for
1885 Z39.50 authentication).
1887 --- 3.0.8 2007/06/25
1889 Fixed bug #1208: SSL appears to be broken in ZOOM.
1891 Fixed bug #1206: Libxml2 include path weirdness.
1893 Added oid_name_to_dotstring.
1895 Allow elementSetName to be specified for ZOOM C record update.
1897 Allow waitAction to be specified for ZOOM C based for Extended Services.
1899 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1900 syntax OID. Bug introduced in YAZ 3 series.
1902 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1904 --- 3.0.6 2007/06/06
1906 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1907 directory. yaz-client now reads commands from file given by option -f
1908 if specified; then tries to read .yazclientrc in current directory.
1909 Failing that, it reads .yazclientrc from user's home directory.
1911 Added support for correlationInfo Note and ID for Record Update via
1914 Added yaz-client command querycharset which specifies character set for
1915 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1916 (termListAndStartPoint).
1918 Charset ISO5428:1984 is an alias for ISO5428-1984.
1920 Implemented a way to perform scan in a result set using Z39.50. This
1921 is achieved by attaching the result set name in the characterInfo
1922 (type InternationalString) of OtherInformation in the Scan Request PDU.
1923 The result set is identified in the otherinformation by the new OID:
1924 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1925 This allows for scan in result set and faceted search . Zebra did some
1926 of this in the APT term using attribute type 8 and value being result
1927 set. Using the OtherInformation approach for this is cleaner and easier
1928 to work with in proxies and the like. This facility can be used in
1929 yaz-client using new command setscan which takes a result set as first
1930 argument, start position (APT) as second.
1932 Changed decoding of SRU XML packed records to deal with servers that
1933 have recordData with XML data with multiple root nodes. Also make
1934 comparison for recordPacking case insensitive. Again, one server
1935 returns "XML" where others return "xml".
1937 For SRU responses allow Content-Type application/xml as well as text/xml.
1939 --- 3.0.4 2007/05/21
1941 Fixed bug in character set conversion of BER strings. Bug introduced
1944 --- 3.0.2 2007/05/08
1946 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1948 For OID class, use oid_class consistently.
1950 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1953 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1954 character set for bibliographic information interchange". By Giannis Kosmas.
1956 Added documentation on new OID API.
1958 --- 3.0.0 2007/05/02
1960 Changes to generic frontend server interface: added new member
1961 'query_charset' for bend_initrequest structure. A backend init handler
1962 should set this member to its native character set for query terms.
1963 When defined, the frontend server logic will announce this character set
1964 to a client if the negotiationModel bit is set by the client. All server
1965 implementors are encouraged to specify this. If a backend server does not
1966 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1968 Added CCL utility to remove terms (stop words) from resulting RPN
1969 tree. This is handled by functions with prefix ccl_stop_words_ .
1971 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1972 terms in RPN queries.
1974 Clean-up the CCL API. Moved some internal structures from ccl.h to
1975 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1976 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1977 This is replaced by ccl_parser_find_str which takes a string instead.
1979 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1980 libyaz.la is the core of YAZ except the generic frontend server and
1981 does not depend on POSIX threads anymore. libyaz_server.la is the
1982 generic frontend server facilities and uses POSIX thread functionality
1983 if available. The libyaz.la no longer depends on POSIX threads because
1984 the number of global structures is limited. NMEM no longer re-uses blocks
1985 between threads ; it simply free's memory immediately but allocates in
1986 "large" chunks as usual. We don't expect any performance penalties
1987 because of this. The yaz_log system is still using a global log_level so
1988 caution must be taken when modifying it with yaz_log_init_.. +
1989 yaz_log_mask_str. This, however, should not cause any trouble because
1990 these functions are called during initialization of application code
1991 anyway. `yaz-config --libs server` returns libs for server applications;
1992 `yaz-config --libs` returns libs for non-server applications.
1994 New OID database - with public definitions in oid_db.h. Removed old OID
1995 database including the head oid.h and definitions such as enum oid_value
1996 and struct oident. The new OID database uses the same string names as
1997 before but the 'protocol' is gone. There are now only two representations
1998 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1999 converts from string to OID; functions with prefix yaz_oid_to_string
2000 converts the other way.
2002 Change to emit_term() in CQL-to-PQF query translation: when a term has
2003 the /regexp relation modifier, do not process it for leading and
2004 trailing "^" and "*", which have quite different meanings in regular
2007 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2008 write handlers no longer carries a 'last' parameter. This will make
2009 yaz_iconv flush "less" characters. A flush is performed by call to
2010 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2012 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2013 removed, because function yaz_query_to_wrbuf does the same.
2015 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2016 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2018 Deprecated MARC utility functions removed.
2020 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2023 Branch split: YAZ_2_1_55_branch
2025 --- 2.1.54 2007/03/16
2027 Fix to ZOOM-C so that transparent reconnection is properly handled on
2028 connections that are in asynchronous mode.
2030 Fixed compilation on OpenBSD 4.0.
2032 Large strings in GRS-1 records are now properly displayed in yaz-client.
2034 Added character conversion support for "advancegreek"; based on patch from
2037 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2038 sequence is met. Before the error was not set so it would be unknown.
2040 Adjust yaz-marcdump MARC reader so that it skips until record separator
2043 --- 2.1.52 2007/03/07
2045 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2046 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2047 fd_set structure used as a bitmask for the FDs to be selected on.
2049 Using ACX_PTHREAD macro to check for POSIX threads.
2051 Fixed have-vsnprintf check.
2053 --- 2.1.50 2007/02/23
2055 Fixes for configure on BSD. Bug #900.
2057 Added snprintf/vsnprintf wrappers for systems that don't have
2058 limits (heavens forbid).
2060 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2061 created before all previous tasks were completed and removed from the
2062 task queue, the new task could be removed by a mistake.
2064 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2066 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2068 Fixed bug #832: Problem with MARC/charset in yaz-client.
2070 Fixed bug #668: save command line history for yaz-client.
2072 Fixed bug #830: pkg-config support.
2074 --- 2.1.48 2007/01/23
2076 Extended ZOOM result set options with two options that may be read by
2077 a client: resultSetStatus and presentStatus with values as specified for
2079 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2081 Fixed bug #827: Using SSL fails on Debian etch.
2083 Fixed bug #826: Weird looking chars for set of MARC records.
2085 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2086 that is treated as an ItemOrder with itemRequest being an XML document
2087 external. The value of "doc" is the content.
2089 Extended the GFS search facility. New member of bend_search_rr
2090 'estimated_hit_count' signals that hits is known to be an estmate
2091 (higher or lower than real hit count). New member 'partial_resultset'
2092 signals that the search was partial (hit count is lower or equal than
2093 real hit count). For Z39.50, the information is stored in resultSetStatus
2094 member of SearchResponse APDU. For SRU, the information is signalled
2095 via SRU diagnostic 59: "Result set created with valid partial results
2098 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2100 --- 2.1.46 2007/01/13
2102 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2104 Added ZOOM_connection_peek_event.
2106 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2107 the following new functions:
2108 ZOOM_event_nonblock, ZOOM_connection_process,
2109 ZOOM_connection_get_{socket,mask,timeout},
2110 ZOOM_connection_fire_event_{timeout,socket}.
2111 The existing blocking event handler, ZOOM_event, is a wrapper for the
2112 + blocking ZOOM_event_sys_{poll,select}.
2114 Implemented function ccl_xml_config which parses XML version of CCL
2115 configuration (bug #798).
2117 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2119 Added timings utility (yaz/timing.h)
2121 --- 2.1.44 2007/01/03
2123 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2126 Fixed bug #779: Rotation of apdu.log fails.
2128 Fixed for character set conversions:
2129 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2130 Honor G1 set in MARC-8 decoding.
2132 --- 2.1.42 2006/12/17
2134 Fixed bug #775: char conversion does not handle Alternative UTF-8
2137 Implemented function yaz_marc_read_line which parses MARC line format
2138 records. There is a wealth of formats out there. So far, this function
2139 reads line records produced by yaz_marc_write_line.
2141 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2142 more generic and easier to remember(!) options: -i format and -o format
2143 which specifies input format and output format respectively - where
2144 format is one of "marc", "marcxml", "line", "marcxchange".
2146 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2147 does not print anything except warnings for records.
2149 For yaz-marcdump, added support for MARC split into files (-s) with a given
2152 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2153 spec, at http://www.loc.gov/standards/sru/record-update/
2154 This has changed the binary layout of the following structs:
2155 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2156 bend_update_rr . Patch by Ko van der Sloot.
2158 Added GFS utility function bend_assoc_is_alive which returns 1 if
2159 association is still alive (client is connected); 0 otherwise (client
2160 closed connection). This allows busy servers to stop working for
2163 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2164 been a separate piece of software. This version of ziffy has been modified
2165 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2167 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2169 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2170 Client code may now interrogate options such as "init_opt_sort" to
2171 find out whether the server claims to support various options.
2173 --- 2.1.40 2006/11/27
2175 Added utilities yaz_{set,get}_esn to set/get element set name from
2178 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2179 of YAZ and has been so since YAZ 2.1.10.
2181 Implemented ZOOM_record_error which returns error information for
2182 record (surrogate diagnostic).
2184 --- 2.1.38 2006/10/31
2186 Updates for SRU Update by Ko van der Sloot:
2187 1. Changed name from "operation" to "action"
2188 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2189 versions in the code, marked as 'backward compatible'.
2190 3. Added diagnostics for SRU Update.
2192 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2194 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2196 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2198 For GFS, fixed problem with SRU diagnostic 'First record position out of
2199 range' being issued for 0 hits.
2201 zoomtst10 part of Windows Build.
2203 --- 2.1.36 2006/10/13
2205 Implemented yaz_filepath_comp which splits a path into file path
2206 components (required by Zebra 2.0.3+).
2208 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2209 BSD inspired license until now so this should not have any real impact on
2210 anybody. See http://www.opensource.org/licenses/bsd-license.php
2212 Fixed bug #687: Missing log lines.
2214 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2217 Fixed bug #689: SRU diagnostics to be added.
2219 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2220 whether a connection is idle (no more work do do).
2222 --- 2.1.34 2006/10/04
2224 Change type of optval from long to int for invocation of setsockopt with
2225 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2227 Added support for specifying the max log file size for the Generic
2228 Frontend Server. The size is given with option -r.
2230 --- 2.1.32 2006/09/21
2232 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2234 --- 2.1.30 2006/09/17
2236 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2239 Fixed bug in Generic Frontend Server that could cause a server to stop
2240 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2242 For the generic frontend server, the maximum record size is used as maximum
2243 size of incoming packages (SRU + Z39.50). The value until was previously
2244 only used in Z39.50 Init negotiation and, later, in a session controlled
2245 sizes of records returned. This is controlled using -k option. It can be
2246 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2248 --- 2.1.28 2006/09/04
2250 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2253 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2255 New option for yaz-marcdump -lpos=value which allows setting a portion
2256 of MARC header to a certain value.
2258 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2260 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2261 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2263 --- 2.1.26 2006/08/15
2265 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2268 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2270 --- 2.1.24 2006/08/08
2272 Fixed MARC ISO2709 encoding routines to deal with character set
2275 Minor changes to GFS logging. Database included in search request log
2278 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2279 cached/multiple records.
2281 Shared libraries are built by default on Unix+configure.
2283 Changed cql2pqf transformation to use a different evaluation order. The
2284 new order is: always, relation, structure, position, truncation, index
2285 and relationModifier. Old order was: always, relation, relationModifier,
2286 structure, index, position, truncation. Note that the the latter ones
2287 override former ones for identical attributes.. The new scheme means that
2288 it is possible to override any existing attribute with a relationModifier.
2289 And also that it is possible to override everything for the index rule
2290 (except the ones listed in relationModifier). No order is perfect but this
2291 one, we believe, covers more real cases.. The "always" should have been
2292 called "default", since the attributes there can be overridden with all
2295 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2296 compilation phase, but also for yaz-config --cflags output. This allows
2297 us to have public headers with Libxml2 stuff in them . It should also,
2298 eventually, make Libxml2 checks redundant in packages using YAZ, such
2301 --- 2.1.22 2006/06/15
2303 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2304 stored in uri, message and details.. Previously diagnostics were stored
2305 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2306 compatibility.. but he's probably the only one affected, so.
2308 Added support for CCL, compiled on the client side, in ZOOM-C. This
2309 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2310 input; the resulting query objects can be used for for searching with
2311 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2313 YAZ' configure searches for OpenSSL by default.
2315 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2316 SL_CTX_use_certificate_file. See
2317 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2318 for more info. Thanks to Ko van der Sloot.
2320 --- 2.1.20 2006/06/02
2322 Bug #600: SRU GET, POST support for yaz-client. Introduced
2323 command 'sru' which selects method SOAP/GET/POST.
2325 Allow missingValueAction to be specified for the sortspec string -
2326 function yaz_sort_spec. By default, the missing value action is null.
2327 Use ! to specify "abort". Use = followed by stringvalue to specify default
2330 Ensured that Present-handler (if defined) is called in GFS before any call to
2331 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2332 searchRetrieve requests.
2334 Documentation for YAZ is now based on the Docbook XML/XSLT using
2335 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2336 is no longer depending on jade/openjade or docbook-to-man scripts.
2337 PDF is no longer part of the distribution - but can optionally be
2338 made using DSSSL/jadetex or FOP.
2340 Added retrieval handling support in Generic Frontend Server to support
2341 conversion between MARC/XML as well as XSLTtransforms. See
2342 etc/yazgfs.xml for an example.
2344 Added Authentication support to Generic Frontend Server in SRU
2345 mode. Authentication using HTTP Basic is supported, as is the use
2346 of 'x-username' and 'x-password' parameters in the request itself.
2348 Added support for a new character set MARC8s identical to MARC8 except
2349 that it converts combined characters to single Unicode characters in the
2350 Latin-1 range (when possible).
2352 --- 2.1.18 2006/04/24
2354 ASN.1 compiler 0.4: generates brief Doxygen file header for
2355 generated .h/.c files.
2357 Utility yaz_iconv now supports conversion to MARC-8.
2359 New facilities for the MARC module. The reading - and writing of
2360 content are separate methods for the yaz_marc_t handle. The following
2361 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2362 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2363 format). Write functions have prefix yaz_marc_write_.. The existing
2364 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2365 available. Removed support for OAI-MARC and simplexml (not the
2366 simplexml from PHP5).
2368 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2369 to be returned for this connection.
2371 --- 2.1.16 2006/03/31
2373 Allow multiple languages and charsets to be specified with
2374 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2375 negcharset iso-8859-1,utf-8
2377 Translation of proximity nodes from CQL into PQF now works.
2379 Moved to automake 1.8, 1.9.
2381 Added function yaz_log_set_handler which allows a log handler to be
2382 installed. This handler will be called for all log messages. Output
2383 to file is also produced; but that can be disabled by passing NULL
2384 fname to yaz_log_init_file.
2386 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2388 For SRW (including GFS), accept application/soap+xml as content-type
2391 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2392 produces NO stylesheet reference even if a default stylesheet is specified
2395 --- 2.1.14 2006/03/14
2397 Updated Windows package to include yazd.dll + yazd.lib for the
2398 Development component.
2400 If the environment variable YAZ_LOG is set, then it is used as a
2401 string indicating the default level of logging to use if not
2402 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2403 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2404 used as before. So, for example, to omit warnings from YAZ logging,
2405 export YAZ_LOG=-warn
2407 cql_transform() now map structure and other attributes before indexes,
2408 so that index-specific structures and other attributes can override
2409 defaults. So now a combination of mapping specifications such as:
2411 index.dc.date = 1=date-modified 4=5
2412 does the right thing.
2414 cql_transform() now also respects the "always" mapping specification,
2415 which establishes an initial set of attributes to be used for all
2416 terms except where overridden by more specific attributes associated
2417 with the index, relation or modifier.
2419 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2420 which mode to use; one of "post", "get" or "soap" (SRW, default).
2422 Fixes for yaz_iconv routines: changed trie-based character set conversions
2423 to use only non-negative values for bit fields due to Sun's C compiler not
2424 supporting negative values.
2426 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2427 sequences where not read correctly. Fix by Rustam Usmanov.
2429 Updated win/makefile to use options, settings which makes things
2430 compile with VS C 2005.
2432 --- 2.1.12 2006/02/01
2434 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2436 In ZOOM socket code, use select instead of poll on MacOSX.
2438 ZOOM-C now support client-side compilation of CQL into RPN that is
2439 sent to the server, enabling CQL to be used against all Z39.50
2440 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2441 ZOOM_query object, and submit it using ZOOM_connection_search().
2442 The CQL-to-RPN translation uses a configuration file, the name of
2443 which must be specified in the Connection's "cqlfile" option.
2445 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2446 function, which takes as its start-term parameter a ZOOM_query object
2447 (which may have had either CQL or RPN set into it).
2450 --- 2.1.10 2005/11/29
2452 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2453 GFS to support this as well. Backend handler, bend_srw_update, does the
2454 update work. Code contributed by Ko van der Sloot.
2456 Allow retrieval of Search Result-1 information in ZOOM by the use of
2457 options that are attached to a result set. ZOOM documentation updated
2460 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2461 UTF-8 conversion. Patch by Raj Patel.
2463 Added option -m to GFS to control formatting of timestamps in log file.
2465 Added 'exit' as synonym for 'quit' in yaz-client
2467 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2468 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2469 for the new members. Patch by Ko van der Sloot.
2471 Added support for SRU POST. It is supported for content-type
2472 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2474 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2475 Instead make the library libyaz.la multi-threaded. Threading as a whole
2476 can still be disabled by configure option --disable-threads. Previosly,
2477 with older GLIBCs there were problems with MT libs under Apache. This
2478 has now been fixed a long time ago.
2480 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2483 CQL module modified to be case insensitive for relations/indexes/operations.
2485 Fixed bug in CQL transform code: incorrect value relationModifieder
2488 Added 'show all' command for yaz-client which retrieves all results
2491 Added new yaz-client, xmles, which takes a (private) OID and
2492 a document to be sent as an extended service request.
2494 Describe new yaz-client commands wait_response and set_auto_wait.
2496 Increase TCP/IP listener backlog from 3 (which I am guessing was
2497 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2498 that the socket will queue as many incoming connections as it's able
2499 to handle ongoing connections. In other words, it will never now
2500 refuse a connection that it would be able to handle merely because
2501 it's not got around to accepting() enough of the pending connections
2502 yet. This is the behaviour anyway under Linux, where the listen()
2503 argument is ignored; but not under BSD and on systems such as
2504 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2505 YAZ-based servers should now be uniform across operating systems in
2508 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2509 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2510 This allows yaz-marcdump to read large MARC batches (>2 GB).
2512 Modified all YAZ source files - except the source which is auto-generated
2513 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2516 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2517 corresponding to the existing *_setl() function. These allow option
2518 values containing arbitrary valuues.
2520 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2521 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2522 except that it returns an indicator of whether or not the sort
2523 criterion was accepted (0 for OK, -1 for invalid).
2525 --- 2.1.8 2005/06/07
2527 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2528 MARC output rather than returning "new" buffer.
2530 yaz-client warns about unknown init options.
2532 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2534 --- 2.1.6 2005/05/24
2536 Added support for SRW sort in Generic Frontend Server. Patch
2537 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2538 sortKeys - or NULL if none is provided.
2540 Fixed bug #307: It was impossible to specify indefinite/no timeout
2541 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2544 Added support for multiple languages and charsets to be specified in
2545 ZOOM. Each charset/language is separated by a blank. If negotiation is
2546 in effect in init-response, Option
2547 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2548 Code based on patch by Vasiliy Osadchuk.
2550 Fixed bug #306: infinite recursion that occurred when calling
2551 yaz_log_level_init as the first call (before other log level or
2554 Fixed bug in scan handling in front end server: if preferred-Position-In-
2555 Response was non-present, a NULL pointer referece was performed.
2557 --- 2.1.4 2005/04/26
2559 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2560 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2561 now defined for all those error codes. So instead of putting 109 in
2562 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2563 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2565 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2568 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2570 Program yaz-client now exits and produces an error message if multiple
2571 Z39.50 servers are specified on the command line (none or one allowed
2574 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2577 --- 2.1.2 2005/03/16
2579 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2581 Fixed bug #272: Preserve spacing for CCL terms.
2583 --- 2.1.0 2005/03/14
2585 Added support for virtual hosts and multiple backend servers for
2586 the YAZ frontend server. The configution is XML based and
2587 support specificition of CQL to RPN mappings and explain information.
2588 See section "Virtual Hosts" in the YAZ manual.
2590 Extended OPAC display utility. OPAC display utility renders
2591 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2592 to supplement yaz_marc_decode_wrbuf.
2594 Fixed a bug in MARC decoder that could caused it to crash for some
2595 invalid MARC records. More diagnostics and warnings where added in
2596 XML output (warnings, etc are stored in comments).
2598 --- 2.0.34 2005/02/08
2600 Fixes for UNIX domain sockets. Bug #261.
2602 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2604 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2605 Added yaz_marc_subfield_str which defines subfield lead string which is
2606 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2607 yaz_marc_endline_str which defines end of fields string used in
2608 YAZ_MARC_LINE format. Default string is newline.
2610 Experimental support for MarcXChange. This format can be produced
2611 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2612 http://www.bs.dk/standards/MarcXchange.xsd
2614 Added yaz-client commands scansize that sets maximum number of
2615 entries to be returned by scan.
2617 --- 2.0.32 2005/01/11
2619 Added support for SRW scan in yaz-client and Generic Frontend Server.
2621 * Added whereInList member to SRW Scan Term.
2623 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2625 Fixed NMEM system to return aligned blocks on the smallest boundaries
2626 that are suitably aligned for all possible types on the particular
2627 architecture YAZ is being built for.
2629 --- 2.0.30 2005/01/04
2631 Fixed numerious warnings that was issued with newer versions of GCC.
2633 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2634 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2637 Make YAZ Generic Frontend Server slightly faster.
2639 Enhance (and reduce) logging for Generic Frontend Server.
2641 Revert YAZ log system so that it flushes every write operation
2642 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2644 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2645 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2646 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2647 will effectively disable old definitions.
2649 --- 2.0.28 2004/11/09
2651 Added yaz_log_time_format which specifies log format using
2654 Added yaz_log_module_level which returns mask for a module. Value
2655 is non-zero mask a if module is enabled; zero if disabled.
2657 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2658 in include/yaz/cql.h.
2660 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2662 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2664 Fixed bug #172: RPM builds does not enable SSL.
2666 Doxyfile.in part of dist. Doxyfile generated by configure.
2668 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2669 are given and the corresponding component does not exist.
2671 Extend CCL documentation in YAZ reference. Describe r=r.
2673 --- 2.0.26 2004/10/01
2675 Fixed MARC->MARCXML conversion to properly deal with
2676 fields, subfields, indicators having non-ASCII characters.
2678 Fixed MARC->MARCXML conversion so that ASCII control characters
2679 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2682 Added YAZ GFS support for conversion from Z39.50 surrogate
2683 diagnostics to SRW surrogate diagnostics.
2685 Bug fix: YAZ GFS did not return schema in explainResponse.
2687 --- 2.0.25 2004/09/30
2689 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2690 now converts recordSchema to elementSetName as well as schema URI.
2692 Fixed bug in COMSTACK that prevented HTTP request packages from being
2695 --- 2.0.24 2004/09/29
2697 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2698 does not require white-space before and after the dash in a range, e.g.
2699 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2702 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2703 due to new GCC removing "redundant" code.
2705 Added yaz-client commands scanpos and scanstep that sets preferred
2706 position and step-size for scan.
2708 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2710 Added CCL utility ccl_qual_buf which parses one or more CCL
2711 spec lines in a buffer.
2713 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2714 of name and value - ignoring empty lines and comments.
2716 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2718 Added odr_get_element_path which returns current element path for an
2719 ODR handle. This utility is useful in error handling or user-defined
2722 Added ODR_PRINT utility odr_set_stream which is is a more generic
2723 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2724 to a write function and pointer to close function. The close function - if
2725 non-NULL - will be called during odr_destroy.
2727 Fixed bug in CCL parser where truncation char was not removed from
2728 right side when truncation=both was in effect.
2730 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2733 --- 2.0.23 2004/08/11
2735 Fix buffer overrun in CQL parser when dealing with proximity (%).
2737 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2738 to UTF-8/UCS conversion is now only based on codetables.xml.
2740 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2742 --- 2.0.22 2004/08/06
2744 Add support for more "commit changes" in ZOOM (uses Extended Services).
2746 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2749 Yet another small fix for configure of SSL.
2751 --- 2.0.21 2004/05/14
2753 Fix SSL libs for configure when --with-openssl=DIR is given.
2755 --- 2.0.20 2004/05/10
2757 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2759 SSL comstack now uses yaz.pem certificate file on server side
2760 by default. Certificate filename can be configured by calling
2761 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2763 Fix bug regarding multiple calls to ZOOM_connection_connect.
2765 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2767 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2768 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2770 ZOOM now allows inspection of X509 peer certificate for verification.
2771 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2773 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2774 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2775 as "modular" but it simplifies things.
2777 Added cs_get_peer_certificate to that returns peer X509 PEM.
2779 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2780 NULL if SSL is unavailable.
2782 Documentation about MARC decoding tools.
2784 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2786 --- 2.0.19 2004/03/30
2788 Rename CHANGELOG to NEWS to follow GNU style packing.
2790 Fix bug with missing initialization of member in init_diagnostics.
2791 This bug affects threaded version of GFS server.
2793 --- 2.0.18 2004/03/20
2795 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2798 Ensure zlib.dll is packed with Windows install.
2800 --- 2.0.17 2004/03/17
2802 Fix encoding of xsd:string to use text instead of CDATA.
2804 Fix endless loop in CQL parser with unbalanced ".
2806 Use a more compact way to store MARC-8 conversion tables.
2808 --- 2.0.16 2004/03/16 Debian only
2810 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2813 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2818 --- 2.0.15 2004/03/01
2820 Another fix for decoding of XML packed records.
2822 --- 2.0.14 2004/02/25
2824 Fixes for Chunked encoding. White space not ignored after length spec.
2826 Update NS and use default NS for SRW diagnostic elements.
2828 --- 2.0.13 2004/02/23
2830 Implement ZOOM_resultset_cache_reset which resets record cache.
2832 Implement ZOOM_resultset_sort which sorts a result set.
2834 Implement chunked HTTP transfer.
2836 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2838 --- 2.0.12 2004/02/16
2840 Added member 'schema' to bend_explain_rr structure so that backend
2841 can specify explain record identifier. Defaults to Zeerex 2.0.
2843 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2845 --- 2.0.11 2004/02/16
2847 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2850 Added init command for yaz-client which sends "extra" init request.
2852 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2853 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2855 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2857 Make ZOOM error code for "invalid query".
2859 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2861 --- 2.0.10 2004/02/05
2863 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2866 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2868 Added option -p <file> to make Generic Frontend Server to write PID file.
2870 Added option -D to put Generic Frontend Server in background on its own.
2872 Make ZOOM C recognize option "password". If unset, "pass" is used
2873 (for backwards compatibility).
2875 Fixed a bug in Generic Frontend Server that could make it crash if a
2876 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2879 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2880 Must be issued before open, in order to be in effect.
2882 --- 2.0.9-6 2004/01/12 Debian/Windows
2884 Make the SRU server more picky WRT unknown params, etc.
2886 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2888 New YAZ client command, options, that sets Z39.50 options.
2890 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2891 options from a string of tokens (one token for each option bit).
2893 Update SRW diagnostic code messages.
2895 --- 2.0.9-5 2004/01/07 Debian/Windows
2897 Handle user defined stylesheet for SRW/SRU.
2899 --- 2.0.9-4 2004/01/06 Debian/Windows
2901 Fix bug in decoding of Content-Length.
2903 --- 2.0.9-3 2004/01/06 Debian/Windows
2905 Fix a bug with decoding of XML packed records.
2907 --- 2.0.9-2 2004/01/05 Debian only
2909 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2911 Fix bug in SRW/SRU diagnostics decoding.
2913 --- 2.0.9 2004/01/05
2915 Fixed bug in Generic Frontend Server which could drop records exceeding
2916 preferred message size. Reported and fixed by Irina Dijour.
2918 Fixed calculation of package size for structured records in Generic
2919 Frontend Server. Reported and fixed by Irina Dijour.
2921 Fixed namespace for SRW/SRU diagnostics.
2923 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2925 --- 2.0.8 2003/12/22
2927 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2928 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2931 CQL changes to reflect recent changes to the specification:
2932 * Documentation talks about context sets instead of index sets.
2933 * Documentation talks about indexes instead of qualifiers.
2934 * The CQL-to-PQF transformer's configuration file now uses
2935 "index.set.name = <attributes>" instead of the old form
2936 "qualifier.set.name = <attributes>". (Both forms are still
2937 understood but the latter is deprecated.)
2938 * CQL terms with no explicit index specified are now interpreted as
2939 cql.serverChoice instead of srw.serverChoice (which of course
2940 behaves exactly the same.)
2942 --- 2.0.7 2003/12/16
2944 MARC conversion can now generate ISO2709 output in another
2945 character set. yaz-marcdump uses this facility if you invoke it
2948 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2949 functions from there can be used from C++.
2951 --- 2.0.6 2003/12/04
2953 Frontend server now transfers memory from decoded packages to stream
2956 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2957 references to show up.
2959 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2960 the ZOOM Abstract API. The older names for the same options are still
2961 also supported for the benefit of old applications.
2963 ZOOM-C supports "implementationId" and "implementationVersion" options
2964 to go along with "implementationName". These allow the user code to
2965 specify identification strings to be sent to servers.
2966 Add OID for the new ExtLite attribute set.
2968 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2969 as requested/supplid by Ere Maijala <ere@atp.fi>
2971 For generic frontend server, reverse the order of
2972 "toolkit-supplied / application-supplied" strings sent as implementationId,
2973 Name and Version. Also, remove the spaces around the slash. This brings
2974 the GFS in line with the behaviour of ZOOM-C on the client side.
2976 Add function ZOOM_scanset_display_term.
2978 yaz-client shows scan displayTerm if present.
2980 Utility yaz-iconv is now installed by default along with the man page
2983 Extend configure check for OpenSSL to use pkg-config where available (such
2986 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2987 server to specify uid/gid/mask for socket using the format
2988 unix:[user=uid,][group=gid,][umask=mask,]file=path
2989 If file= is omitted the existing format is assumed, e.g.
2991 in which case the mask is 0666 (rw for everybody).
2993 Major restructure of YAZ source. All source in libyaz is in src directory.
2994 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2995 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2997 Added man page for utility yaz-marcdump (used to be called marcdump).
2998 yaz-marcdump is installed by 'make install'.
3000 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3001 of incoming package failed.
3003 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3005 Change prototype of odr_perror: add const to message string.
3007 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3009 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3010 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3011 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3012 DNS lookup. There should not be any compatibility problems with this
3013 assuming that blocking=1 or 0 is used.
3015 Fix bad reference in UNIX comstack in function cs_addrstr.
3017 Fix for compilation on AIX.
3019 The generic front-end server (server/seshigh.c) now supports returning
3020 Init diagnostics to the client in User-information-field, in
3021 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3024 --- 2.0.4 2003/09/04
3026 Allow any CQL relation (not just all,any,exact,scr).
3028 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3029 that features the same UI.
3031 Implemented command update0 in YAZ client which is equivalent to
3032 update but uses old of Ext Update ASN.1.
3034 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3035 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3036 Previously no OID was used for this info.
3038 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3039 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3040 returns 'malformed search term' otherwise.
3042 SortResponse member resultCount now set to NULL in sort handler of
3045 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3048 Add three new utility functions for translating OIDs between various
3049 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3050 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3051 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3052 char *oid_to_dotstring(const int *oid, char *oidbuf);
3053 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3055 Reverted modifications for ES Update definition for z_IU0Update
3056 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3057 is back to YAZ 2.0.2.
3059 String value attributes for CCL parser.
3061 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3062 which their FirstSearch server returns in Init responses, sometimes
3063 carrying useful diagnostic information when Init fails. This has the
3064 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3065 "z39.50/oclcui.asn", where its definition is somewhat different from
3066 what OCLC document on their web-site, as required to interoperate with
3069 Support for anonymous authentication in yaz-client. Use the command
3072 * Fix the OID of the Index Data-local "admin" Extended Service from
3073 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3074 the 1000, which indicates a locally-defined OID, was a mistake.
3076 --- 2.0.3 2003/06/20
3078 Fix CCL directive @case handling so that it affects string match for
3079 both CCL keywords and qualifiers.
3081 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3082 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3083 Decoder has been updated with ASN.1 changes as listed in
3084 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3085 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3086 z_IUUpdate, remains unchanged.
3088 ZOOM_record_get may now return a record in a specific character set.
3089 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3090 "from" is the character set of record as returned by target. "to" is
3091 the character set to be returned. If omitted, "to" is UTF-8.
3093 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3095 New ODR utility, odr_getelement, which returns name of element for
3096 which encoding/decoding failed.
3098 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3099 in cases where a required element was omitted.
3101 Bug fix: some MARC8 sequences were not converted.
3103 New ZOOM option "step" which specifies number of records to be
3104 retrieved in one chunk. Used in conjunction with "start" and "count".
3106 SRW support for yaz-client. Use scheme http: to use it, e.g.
3109 yaz-client no longer does (un)intelligent character set conversions
3110 by default. Can be enabled with charset and marc_charset commands.
3112 xmalloc trace fix for 64-bit systems such as DEC alpha.
3114 Solaris 2.6 compile fix.
3116 New function, cql_strerror() translates SRW error codes, as returned
3117 by cql_transform_error(), into human-readable English strings. Used
3118 in yaz-client diagnostics when appropriate.
3120 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3121 converts it into a type-1 query which is sent to the server. This
3122 makes CQL available for use with all Z-servers, as opposed to the tiny
3123 minority that can handle CQL queries themselves.
3125 --- 2.0.2 2003/04/28
3127 New Debian package layout similar to the Redhat Package layout.
3129 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3130 and search result respectively.
3132 --- 2.0.1 2003/04/25
3134 Redhat package is now several packages: libyaz (runtime libraries),
3135 libyaz-devel (development and documentation, and yaz (utility programs).
3136 Package spec file by Morten Bogeskov.
3138 New member 'schema' in struct bend_fetch_rr which the name of requested
3139 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3140 handler MAY set this to reflect the schema of the returned record.
3142 New member 'display_term' in struct scan_entry. GFS now sets member entries
3143 and allocates scan entries to be filled by user scan handler. In previous
3144 version, entries member was allocated by the scan handler. That still works,
3145 but the GFS will ignore member display_term - assuming it was NOT set by
3146 the handler. The fact that the GFS now allocates the entries both allows
3147 for new members and makes a scan handler easier to write.
3149 Fix CQL lex buffer overflow.
3151 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3152 SRU default recordPacking is string.
3154 SRU protocol support for frontend server.
3156 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3158 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3160 Added scan for the ZOOM shell (zoomsh).
3164 * String Identifers for Schemas (Amendment 5).
3165 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3166 Old definition for schema
3167 Odr_oid *schema; /* OPT */
3172 Z_InternationalString *uri;
3173 #define Z_Schema_oid 1
3174 #define Z_Schema_uri 2
3177 * resultCount parameter to Sort Response (Amendment 1).
3178 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3180 Support for SRW 1.0 over HTTP. This is an optional feature and
3181 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3184 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3185 on the same port. SRW SearchRetrieveRequests are mapped
3186 to bend_init,bend_search,bend_fetch,bend_close.
3188 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3190 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3191 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3193 ZOOM connections are SRW based if schem http is used for hostname
3194 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3195 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3197 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3198 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3199 distance=n, order=true/false, relation=le, prox unit=word. If
3200 n is omitted, distance 1 is used.
3202 Fixed problem with C compiler include path in wrong order.
3204 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3205 on Solaris. Patch from Ko van der Sloot.
3207 New MARC decode API. All new functions operate on a yaz_marc_t
3208 handle. The most important new functions are: yaz_marc_create,
3209 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3210 decode and destroy respectively. Decoder can produce formats
3211 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3212 include/yaz/marcdisp.h.
3214 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3215 to UTF-8, UCS-32, wchar_t or Latin-1.
3217 * Prototypes for yaz_iconv_-functions moved to separate header
3218 include/yaz/yaz-iconv.h.
3220 Make a few private functions 'static' in unix.c. This prevents
3221 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3223 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3224 are set when Init Response is received.
3226 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3227 but returns diagnostic set as well.
3229 New function yaz_strerror which is a portable wrapper for
3230 strerror/strerror_r/GetLastMessage.
3232 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3233 is returned for MARC. If type is "oai", then OAI MARC is returned.
3235 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3238 --- 1.9.2 2002/11/26
3240 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3242 Fix bad race conditions on SIGTERM and terminate gracefully in
3245 Move retrieval (data1) module to Zebra since nobody seems to be
3248 Add GRS-1 render for ZOOM using same format as yaz-client.
3250 --- 1.9.1 2002/10/05
3252 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3254 Fix broken ESpec handling in data1 module.
3256 SGML reader parses comments and makes them part of the data1 tree.
3258 Added several type casts so that YAZ compiles as C++ code.
3260 ZOOM didn't handle PDU encoding failures properly.
3262 Added more Bib-1 diagnostics (approved extensions).
3264 GNU configure: better check for iconv.
3266 More portable use of accept, getpeername. Check for socklen_t. Use
3267 int/size_t if socklen_t is not defined.
3271 PQF parser rejects bad queries - including those with extra
3272 characters in them. PQF parser used to silently ignore that.
3273 Cleaner API for PQF added, which allows you to get detailed
3274 error information for bad queries (see yaz/pquery.h).
3276 Fixed bug in ZOOM_record_get for type "database".
3278 Implemented mini iconv library supporting conversions between
3279 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3281 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3283 --- 1.8.9 2002/08/20
3285 Fixed ZOOM C record cache so that preferredRecordSyntax and
3286 elementSetName is used to check for already fetched records.
3288 --- 1.8.8 2002/08/02
3290 Added three members in bend_initrequest structure to facilitate
3291 character set negotiation.
3293 Fixed a bug in frontend server that could cause indefinite
3294 loops under rare conditions.
3296 Revised character set utilities (charneg.h) so that encoding
3297 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3299 For PQF, directive @term <type> sets term type for Scan/Search.
3300 Here <type> is general, string, numeric, null. The term type
3301 is inherited - just like @attr.
3303 New call odr_set_charset that sets character set conversion for
3304 international-strings on a ODR stream. Prototype is:
3305 int odr_set_charset(ODR o, const char *to, const char *from);
3306 The InternationalString is still represented as C string in YAZ
3307 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3308 won't). On the protocol level, you can use any encoding.
3310 Support for UNIX sockets in ZOOM.
3312 Solaris recv sometimes returns errno == ENOENT. It is treated as
3313 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3315 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3316 both client and server. Code by Morten Bogeskov.
3318 --- 1.8.7 2002/05/22
3320 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3321 that they can be used directly from Visual Basic. You must recompile
3322 your windows APP if you're using ZOOM.
3324 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3325 Commands "lang" and "charset" sets language and character set respectively.
3326 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3327 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3329 Attributes from multiple CCL fields may be OR'ed rather than merged
3330 using directive "@field or". Fields are still merged by default -
3331 equivalent to "@field merge".
3333 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3336 Fixed bug in zget for parameter ExtendedServicesResponse.
3340 --- 1.8.6 2002/03/25
3342 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3344 Client displays USR.1:SearchResult-1 (hits per term).
3346 Additional Search Info for search in Generic Frontend Server.
3348 Fixed CCL parsing of "field=s".
3350 WIN32 installer - using the excellent NSIS software from nullsoft.
3352 Fixed CCL parsing of "field = - <number>".
3354 Added function yaz_marc_decode that decodes MARC for line mode
3355 display or XML (similar to that used by JZKit).
3357 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3358 Z39.50. But ISO/ILL was, however.
3360 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3361 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3363 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3364 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3366 --- 1.8.5 2002/02/03
3368 New YAZ client features: Command completion and new commands:
3369 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3370 Code provided by Jacob Poulsen.
3372 New call oid_trav, that visits all registered OIDs via callback.
3374 Function ZOOM_record_get now returns const char pointer rather than
3375 void pointer. It saves a lot of type casts.
3377 For YAZ client, command "auth" now allows you to set authentication
3378 in IdPass style. It is enabled when three tokens are given - order
3379 is user, group and password.
3381 Fix memory leaks in MARC record handling for ZOOM.
3383 New option for YAZ client, -k <kilobytes> that sets
3384 maximum record size. Similar to -k option for generic frontend
3385 server and yaz-ztest.
3387 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3389 Prefix query parser reports "fail" when bad attribute set is given.
3391 Fix in MARC decoder. Proximity logging. Fix for attribute set
3392 in scan handler for server. Patches by Shigeru Ishida.
3394 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3397 Configure option --with-openssl=<dir> now works when a directory is
3398 specified. Patch provided by Morten Bogeskov.
3400 New option for YAZ client, -u <auth>, that sets authentication.
3402 ZOOM fix: error information was sometimes "missing", since error
3403 was cleared/reset too when it shouldn't.
3405 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3407 --- 1.8.4 2002/01/04
3409 Scan for ZOOM API. New object ZOOM_scanset. New functions
3410 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3411 ZOOM_scanset_destroy.
3413 New ZOOM function, ZOOM_connection_last_event, that returns type
3414 of last event (such as "receive data", "send data", "apdu received",
3417 New ZOOM option, schema, that specifies schema for retrieval.
3419 New CCL feature. Qualifiers can be aliases for one or more
3420 other qualifiers (if more than one is given, OR is used).
3422 ZOOM uses named result sets if target supports it.
3424 Two new YAZ client commands: . (dot, which sources a script of YAZ
3425 client commands), and ! (to execute shell command.). Implemented
3428 Working on Debian packages.
3430 --- 1.8.3 2001/11/19
3432 YAZ client enables named result sets only if target supports it.
3434 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3436 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3437 with key="host" to get same result.
3439 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3440 Function Z3950_resultset_record(s) returns references to records
3441 "owned" by resultset. To become owner use Z3950_record_clone.
3443 Function z_ext_record handles Extended Services. Thanks to
3446 --- 1.8.2 2001/11/12
3448 CCL Parser fix: ignore token comma when dealing with and-lists.
3450 Documentation updates for COMSTACK.
3452 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3453 Changed prototype Z3950_records. For some functions, int parameters
3454 were changed to size_t.
3456 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3459 New MARC decode/display function, marc_display_exl, which properly rejects
3460 non-ISO2709 records. YAZ client uses it.
3462 --- 1.8.1 2001/10/29
3464 Fix bug: local attribute set wasn't set correctly in PQF strings.
3468 * Old Z39.50 codecs no longer supported.
3470 Added ZOOM C binding. See http://zoom.z3950.org/
3472 Renamed states for COMSTACKs to avoid confusion with events.
3474 Implemented cs_look and proper cs_rcvconnect.
3476 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3478 Configure detects POSIX threads on OpenBSD.
3480 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3481 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3483 When error is returned from present handler, non-surrogate diagnostic
3484 is returned in present response (and fetch handler is no longer called).
3486 * Minor adjustments to pquery parser (PQF). Token characters may be
3487 escaped by using backslash (C-style).
3489 PQF parser allows string attribute values to be specified. For @attr,
3490 non-numeric characters after the equal-sign are treated as strings
3491 (e.g. @attr 9=title).
3493 CCL trunction character may be defined (@truncation in file)
3495 * function zget_ExtendedServicesRequest sets waitAction to
3496 waitIfPossible (was wait).
3498 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3501 CCL operator names may be set in field definition files (CCL_bibset).
3502 See ccl/bib1 for an example.
3504 Fixes in ASN.1 compiler for C++ compatibility.
3506 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3507 and "op_or" to avoid conflict with C++.
3509 Fixed problem with GNU readline detection on Redhat 7.0.
3511 Added step-size for Scan backend handler.
3513 Fixed bug that made the frontend server crash when no attribute
3514 set was specified for scan.
3516 Front-end server automatically switches to original working directory
3517 when installed as an NT service. Previously -w had to be specified to
3520 Added extended attributes for retrieval module (data1), so that data1
3521 records carry d1_readXML/SGML attributes. d1_read also supports
3522 null-data rules ( <tag/>)
3524 On UNIX when POSIX threads are available, a separate library libyazthread
3525 is created. Programmers should link with that library and the yaz library
3526 when using threads. The reason for the split was that some applications
3527 on Linux, such as Apache, doesn't work well when using shared objects that
3530 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3531 (or any frontend server) in SSL mode by specifying ssl: followed by
3532 address. Only tested on UNIX.
3534 Added feature for CCL module. Virtual structure s=al or s=ol generates
3535 and-list and or-list respectively instead of phrase search.
3539 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3540 log_mask_str. This was done to avoid name conflicts with other libraries
3541 (such as other PHP extensions).
3543 Added raw OID member for preferred record syntax (request_format_raw)
3544 and returned record syntax (output_format_raw) for backend fetch method.
3546 Config file yaz-config now accepts options so that it returns specific
3547 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3549 Shared library support for UNIX using GNU libtool.
3551 * Modified backend interface. Request/Response struct's replaced by
3552 one read/write C struct. For example bend_fetchrequest and
3553 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3554 Every handler - even search has to be registered in bend_init
3555 handler. This means that the YAZ library no longer refers to
3556 external functions and it makes it possible to make the whole
3557 thing a single DLL/SO.
3559 Added Segment handler for backend server.
3561 Added Zmbol/Zebra administrative functions to YAZ client.
3563 Threaded frontend server on UNIX (when POSIX Threads are available).
3564 Starting the server with option -T enables multi-threading.
3568 Added configure option --enable-comp/disable-comp to control use
3569 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3570 located in sub directory asn.
3572 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3573 in ${exec_prefix}/bin along with the other programs yaz-client and
3576 GNU automake used to maintain makefiles.
3578 Added several OID's.
3580 Changed retrieval module so that we can load records with no abstract
3581 syntax defined. Tagpaths in these records are fully composed of string
3584 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3588 On UNIX, the generated makefile now supports a proper 'make install'.
3589 The prefix can be set via GNU configure to set the install location
3590 (default is /usr/local).
3592 * YAZ programs client and ztest were renamed to yaz-client and
3593 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3594 locations, such as /usr/bin,/usr/local/bin,etc.
3596 * YAZ Header files were moved from include to include/yaz. YAZ Header
3597 files are referred to as include <yaz/log.h> rather than <log.h>.
3598 The YAZ include path (-I ..) is therefore the same as before. Programmers
3599 should update their #include statements or use -Ipath/include/yaz
3600 instead. The main motivation for doing this change is that YAZ header files
3601 can be installed in "standard" locations /usr/include,/usr/local/include
3602 without introducing conflicts, since ALL YAZ header files are stored
3603 in subdirectory yaz (under /usr/include for example).
3605 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3606 rather than project/workspace files. We switched because project files
3607 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3610 Changed name of logging function, logf, to yaz_log, to prevent name
3611 clash with some math-log functions. The YAZ header log.h defines logf
3612 to yaz_log (#define) so there should be no incompatibilities by this
3615 Added bend_start/bend_stop handlers for server. These handler are
3616 called on start/stop of server. For windows they are called whenever
3617 a service is started/stopped.
3619 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3620 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3621 in util/yc.tcl. The auto-generated C code structures are, in a few
3622 cases, incompatible with the old decoders. There are differences in the
3623 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3624 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3625 The preprocessor variable ASN_COMPILED is defined when the compiled
3626 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3627 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3628 wish to use the old encoders/decoders you can specify --disable-yc
3631 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3632 version so that it supports both new - and old version of DB Update
3634 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3635 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3636 change. The name parameter can be set to 0 in which no name is specified
3637 for the construction. The macros odr_implicit and odr_explicit sets name
3638 parameter to zero for the construction involved. New macros
3639 odr_implicit_tag and odr_explicit_tag are similar to the others,
3640 except that a name parameter is added. For programmers' that don't use
3641 ODR they probably only need to change the call to z_APDU and z_External.
3643 Added access control facility by interfacing the TCP wrapper library.
3644 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3645 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3646 name of the daemon and enables the access control as specified in
3647 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3649 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3650 den Dool <H.M.vdnDool@kub.nl>.
3652 Added reference ID parameter to most functions in server API - refer
3653 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3655 Changed name of ccl library to libccl.a (was ccl.a).
3657 Fixed bug in decoder for Explain (Category TargetInfo).
3659 Added support for GNU readline in client. Thanks to Jacob Poulsen
3660 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3662 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3663 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3664 IMPLEMENTATION! This change was made to the development version before
3665 the ZIG decided to retract the amendment. If any users MUST be
3666 compatible with the original Update definition, PLEASE CONTACT US, and
3667 we will include a separate definition corresponding to the old Update
3668 ES. Note that because of the change to the ASN.1 of the
3669 TaskPackageRecordStructure we cannot define a single structure that
3670 will support both versions.
3672 * Added const modifier to buffer parameter for some ODR/BER encoding
3673 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3674 completeWAIS, odr_dumpBER.
3676 Fixed bug in client.c which caused a crash when a scanResponse didn't
3677 contain positionOfTerm.
3679 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3680 * will cause an error in a client if a non-YAZ target sends both a
3681 * list of Scan entries and non-surrogate diagnostics.
3683 Retrieval module enhancements. Tag sets may be typed in the reference
3684 to it. From the .abs-file the "tagset" directive takes a third optional
3685 integer type for the tag set referenced. From a .tag-file the "include"
3686 directive takes a third optional type as well. The old "type" directive
3687 in the tag set itself is still recognized but acts as the default type
3690 Backend interface change. Individual Scan terms returned from bend_scan
3691 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3692 in include/backend.h.
3694 Retrieval module enhancements. Multiple tag sets and attribute sets may
3695 be specified in abstract syntax specs. Revised the error/warning for
3696 logging messages reported by the retrieval module when reading the
3699 Object Identifier system (oid_..) changed. The API is backwards
3700 compatible but the oid-routines now allocates new OID's when needed.
3701 Raw OID's may be specified in oid_getvalbyname.
3703 YAZ now uses GNU configure to generate Makefile(s).
3705 * Minor changes in some of the member names of DeleteResultSetRequest and
3706 DeleteResultSetResponse. See include/proto.h.
3708 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3709 and added member 'languages' in TargetInfo (which was missing).
3711 Changed the way attribute sets are handled in the retrieval
3712 module. These are now cached, just like the abstract syntaxes
3715 Changed YAZ so that it links with compiled ASN.1.
3717 Added Explain-schema definitions and mapping routines. The following
3718 Explain categories have been implemented: AttributeDetails,
3719 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3721 Fixed minor bug in Windows version of Server Library.
3723 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3725 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3727 Added EXTERNAL: UNIverse Resource Report (non-standard).
3729 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3730 ENUMERATED and SET OF.
3732 * Added 'const' to some of the char pointer arguments for the
3733 functions, data1_read_node, data1_getelementbytagname,
3734 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3737 Fixed bug in data1_insert_taggeddata - the last_child member of
3738 parent wasn't initialised.
3740 * Changed data1_read_record and data1_read_node so that the supplied
3741 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3742 doesn't refer to any parts of the "SGML"-buffer.
3744 Fixed bug in server library (Windows version of statserv_remove).
3746 * Changed code so that it compiles as C++. The type definition
3747 of Odr_fun which is a member of Odr_arm was changed. The result is,
3748 that an explicit typecast is needed for the fun pointer when
3749 using Odr_arm - as in:
3750 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3752 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3754 Implemented the new structured date and time definition as approved
3755 by the ZIG. Added schemaId element to the specificTag in Espec-1
3756 (also approved at the last ZIG). Thanks to RVDM.
3758 Added some Object identifiers (RVDM).
3760 Changed the Update Extended Service (RVDM).
3762 Added command "refid" to client which specifies referenceId for
3763 the following requests.
3765 Implemented extended service handling for server. See ztest.c
3766 for an example as well as backend.h. New handlers are registerd
3767 in the Init handler.
3769 * Changed interface for sort in server.
3771 Added new members to statserv_options_block. It allows a server
3772 to read options from another source than just the command line. Thanks
3773 to Charles Woodfield.
3775 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3776 renamed to zboolean. Some C++ compilers complained about the name.
3778 Minor changes to gils.abs. Added index 's' (sort) on title
3779 and date/time-last-modified.
3781 --- 1.4pl2 1998/1/30
3783 Fixed bug in server library regarding inetd mode (-i). This bug
3784 was introduced by release 1.4.
3786 --- 1.4pl1 1998/1/29
3788 Added sort facility in client and backend server interface.
3790 Fixed problem with dependencies in Makefile(s).
3792 Fixed bugs for encoders/decoders of extended services and
3795 Implemented sub-tree feature for schemas. Sub-trees are
3796 referenced in *.abs-files. See explain.abs for an example
3797 of the use of this feature.
3799 Modified bib1.att; local attributes for ANY didn't include
3800 ANY itself (only affects use of the retrieval module).
3802 Fixed bug in plain SGML reader in function data1_read_node:
3803 tags with prefix "var" was incorrectly interpreted as variants.
3805 Added feature "sub-schemas" to enable references to - and definitions
3806 of - group of elements.
3808 * Removed member parent from type data1_element (in data1.h).
3810 Implemented function odr_nullval() that returns the value of
3813 * Removed member num_children from data1_node (in data1.h).
3815 Made NT service interface part of the server library. The
3816 function statserv_main uses the NT service when required and
3817 calls the statserv_start / statserv_close routines.
3819 Routine zget_SearchRequest and zget_PresentRequest fills
3820 resultSetName/Id member with "default" instead of "Default".
3822 Fixed memory leak in server. Request queue member wasn't freed.
3824 Fixed nmem_exit so that memory is freed.
3828 Revised the CCL parser utility to be thread safe.
3830 Added function, oid_ent_to_oid, to replace the function
3831 oid_getoidbyent, which is not thread safe.
3833 * Added nmem_init and nmem_exit to initialize and release
3834 NMEM resources. Function nmem_init should be called once in the
3835 initial thread before NMEM/ODR is used. statserv.c and client.c
3836 have been changed accordingly. The change was necessary to make
3837 NMEM thread safe. The NMEM memory pool is shared amongst threads
3838 in a process. Unix-based applications will still work fine without
3841 Added NT Services interface for the the Z39.50 (statserv) Server.
3842 Refer to the ztest.c source on the usage.
3844 Windows 95/NT port using MSVC5.0. Project files are included in the
3847 * Defined new 'global' handle for the retrieval (data1) system. The
3848 new handled, data1_handle, describes the state of the data1 system.
3849 This handle is passed as first argument to virtually all
3850 data1 related routines. The functions data1_create and data1_destroy
3851 creates and destroys a data1 handle respectively.
3853 Added ODR encode stream member to all backend request structures
3854 init, search, scan etc. This stream should be used to allocate all
3855 memory used for the response when thread safe operation is needed.
3857 Changed the comstack utility, cs_addstr, to be thread safe. The
3858 returned hostname string returned by the function is now part the
3861 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3862 function. The cs_straddr takes a COMSTACK handle as argument, so this
3863 function must be used after cs_create and before bind/connect.
3864 This function is thread safe.
3866 Moved test server to 'ztest' directory - generic server code still
3867 in 'server' directory.
3869 Made prefix query (pquery.c) utility thread safe.
3871 Added new function modifier YAZ_EXPORT to 'export' public DLL
3872 functions when using windows (see include/yconfig.h).
3874 Added definitions to the OID database (util/oid.c) (RVDM).
3876 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3878 Added call to ccl_rpn_delete in client program.
3880 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3881 release of RPN structure.
3883 Added support for C++, headers uses extern "C" for public definitions.
3884 With input from RVDM.
3886 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3887 Thanks to Ronald van der Meer (RVDM).
3889 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3891 Added support for private extensions to the OID database
3892 (oid_setprivateoids()). Thanks to RVDM.
3894 Added optional, physical ANY (key replication)
3896 Fixed null-reference problem in GRS-1 output filter.
3898 Proximity operator added to Prefix Query Format (PQF).
3900 In test client command "base" accepts multiple databases.
3902 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3906 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3908 Smallish bug-fixes in the new encoders/decoders (explain).
3910 Bug fixed in DeleteRequest.
3912 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3914 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3916 Added SOIF syntax (using private OID for now) to retrieval module and client.
3918 Added Update extended service.
3920 Added SearchResult-1 additional info structure.
3922 Added optional CCL (ISO8777) interpreter as separate module. Available
3925 --- 1.2 1996/6/10 (1st anniversary release)
3927 Added Summary record syntax. Lightly tested.
3929 Added OPAC record syntax. Untested.
3931 Added ResourceReport service encoders/decoders. Untested.
3933 Fixed bug in z_Unit - wrong tagging on unitSystem.
3935 Fixed bug in the DiagRecs decoder.
3937 Added options for max PDU size and session timeout to frontend-server.
3939 Added documentation of query-language parsers and other supporting utilities.
3941 [frontend-server] Added Attribute set to the bend_scanrequest API.
3943 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3944 surrogate diagnostics were generated.
3946 [retrieval] Allow multiple local values for attribute.
3948 [retrieval] Allow multiple attributes per element in .abs files. index type.
3950 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3952 --- 1.1pl2 1996/4/10
3954 Minor changes, mostly specific to Zebra's requirements (retrieval)
3958 Repaired bug in frontend server when running multiple listening
3959 endpoints in dynamic mode.
3961 z_External() now won't break if a known, ASN.1 value comes encapsulated
3962 in an octet-string. The value will pass through unmodified in an Odr_oct.
3964 Added a bit of code to the demo client to decode & display
3965 ASN.1-structured records represented in the octet-aligned branch of
3966 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3968 Added z_ext_getentbyref() to the ASN module. Doc updated.
3970 * Completed the SCAN definition in the ASN module. This may break SCAN
3971 code based on older YAZ-versions at compile-time. The fix is easy -
3974 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3975 under the SCAN definition. Remember to initialize this, server-people.
3977 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3978 that this does not extend to ODR and ASN.
3980 Comstack allows insertion of established socket (primarily for
3981 inetd-operation of servers). Doc updated.
3983 Front-end server can now start from the inetd in TCP mode. Doc
3986 --- 1.0pl4 1996/1/24
3990 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3991 the rank and record number.
3993 Adjustments to the frontend server.
3995 Fixed diagnostic BER dumper. It ignored the file argument.
3999 Various changes to retrieval module.
4001 Changed the union discriminators of the protocol files from enums to
4002 ints paired with #defines.
4004 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4007 *Changed operator in the RPN structure to 'roperator', again to avoid a
4010 Fixed problems in Explain decoders/encoders.
4012 --- 1.0pl2 1995/12/6
4014 Memory bug in log module fixed.
4016 --- 1.0pl1 1995/12/5
4018 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4020 Bug in Explain DatabaseInfo module fixed.
4022 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4026 The shift to v1.0 signals that we now consider the *core* functionality
4027 of YAZ reasonably stable (the core being more or less equivalent to
4028 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4029 tested (Explain not at all - though that will happen soonish).
4031 Minor changes to code to support Windows port.
4033 Various minor changes after we're getting to use GRS-1 & co. more.
4035 Added Espec-1 format.
4037 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4038 of the protocol and it cannot be selected when encoding (maps into 'string'
4039 when decoding). Needed to talk to some servers.
4041 Demo client can request simple element set names.
4043 Added Diagnostic Format encoders/decoders.
4045 Added simple Close handling to frontend server (no hooks for resource
4046 reporting yet), and demonstration client.
4048 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4050 --- 1.0b3 1995/08/24
4052 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4053 handled incorrectly when records were requested in the searchResponse. This
4054 will only affect you if you use the frontend-server.
4056 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4057 Test-client will ask for and print GRS1. Ztest will return dummy records
4060 Added Explain encoders/decoders to the service-level API. Untested.
4062 Added Extended Services: Item Order encoders and decoders to the Service-
4063 level API. Untested. We could use a recent copy of the pertinent bits
4064 of the ILL protocol to add those bits.
4066 Added diagnostic format 1 encoders/decoders to the service-level API.
4069 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4070 odr_cons.c, which causes a more correct output.
4072 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4073 was always set to 0 when no records were requested in the searchRequest.
4075 * Added better external-handling. This shouldn't harm old code that
4076 *encodes* externals. It can break code that looks for a
4077 'single-ASN1-type' representation, since those types that are known
4078 are now decoded immediately. Look at the SUTRS sample code in
4079 seshigh.c and client.c. Documentation updated.
4081 Handling of structured records in bend_fetchresponse. Length -1 marks
4082 structured record, type is deduced from format field.
4084 --- 1.0b2 1995/06/27
4085 Fairly quick maintenance release to add SUTRS support.
4087 Fixed handling of SUTRS records in the demonstration client.
4089 * Added format field to the bend_fetchrequest and bend_fetchresponce
4090 structures of the backend API (frontend server). When the record is
4091 returned, the value of the format field is mapped to an OID. The
4092 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4093 of the record. The special value VAL_NONE in the bend_request means
4094 that no specific format was requested by the client. Documentation
4095 updated accordingly. Test server (ztest) will return a fixed dummy
4096 SUTRS record if your client requests SUTRS.
4098 Documentation updated accordingly.
4100 You can now set external libraries and RANLIB support in the top-level
4104 First public release.
