8 Stop building debs for Ubuntu raring, quantal, oneiric.
10 CCL YAZ-781: for multiple use attributes in a specification the
11 generated RPN will perform @or on each term.
12 For spec: term u=31 u=1016
13 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
15 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
17 CCL YAZ-779: combo qualifier should allow for forward references
19 Fix buildconf.sh, automake too old on centos5 YAZ-778
20 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
21 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
22 accepts it without a warning.
26 GFS: client_query_charset conversion YAZ-777
27 This is a feature for Z39.50 clients that sends queries that are not
28 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
29 encoding given to UTF-8.
31 Echoed SRU arguments support YAZ-776
32 This is achieved with new function yaz_srw_get_pdu_e.
34 ZOOM: expire times set for redis/memcached YAZ-772
35 For both redis and memcached option --expire=seconds sets expire
36 time for a result-set/search. Default time is 600 seconds (10 minutes).
40 No [rest of output is omitted] limit for yaz_log YAZ-774
42 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
44 For ICU testing, pass -o to yaz-icu. This will test the
45 icu_iter_get_org_info function.
47 Fix null ptr reference for freeReplyObject YAZ-773
51 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
53 RPM: do not build with libmemcached support. The libmemcached library
54 on CentOS 5/6 does not work reliably for us (redis to the rescue).
56 configure: only allow libmemcached version 0.40 or later. That's the version
57 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
58 that's not an option, consider redis.
62 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
64 Fix zoom+memcached: present request out of range YAZ-767
68 CCL: add new qualifier r=omiteq which will omit relation=equals
69 for ordered relations. This should be used in combination with either

90 wrbuf_cstr: fix off by one error.
92 wrbuf_buf: make it always return non-NULL
93 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
97 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
99 zoomsh: offer option -a apdulog
100 As we're used to from yaz-client and GFS based servers.
102 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
103 existing setting apdulog takes effect.
105 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
110 Add re-entrant CQL/Solr/RPN query conversion functions.
111 The re-entrant functions are: cql_transform_r,
112 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
113 These have same functionality as cql_transform,
114 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
115 return the additional infomration as WRBUF to make them re-entrant.
117 Remove CQL to Solr conversion and base solr_transform_t on
118 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
119 data structure as cql_transform_t.
121 cql2pqf utility allows RPN to Solr conversion

135 Offer new utility function zget_AttributeList_use_string.
137 New conversion step, solrmarc, for record conversion module.
139 --- 5.0.20 2014/03/13
141 Fix gcrypt initialization for threaded mode. On systems were GnuTLS

145 --- 5.0.19 2014/03/10
147 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
148 The standalone ZOOM sort was completely broken since 5.0.13.
150 ZOOM: generate event Connect rather than None for partial connect
151 (in fact getaddrinfo resolving).
153 ZOOM: only supply clientIP for InitRequest. Rather than for all
156 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
158 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
159 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
160 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
162 New "Facets" section in the documentation.
164 --- 5.0.18 2014/02/27
166 Call exsltRegisterAll in yaz_init_globals, so that all applications
167 using YAZ will have EXSLT things enabled.
169 Use extraArgs in key for memcached ZOOM C caching YAZ-747.

175 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
176 introduced in 5.0.12.
178 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
179 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .

193 Describe memcached option for ZOOM.
195 ZOOM: throw present request out of range again YAZ-739
196 Was removed in YAZ 5.0.13.
198 --- 5.0.13 2014/02/18
200 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
201 with localtime_r when threads + fork is used (such as Metaproxy).
203 yaz-config: quote some RHS values (that might include blanks)
205 zoomsh: shows SearchResult-1
207 zoomsh: sortby command
209 zoomsh: use proper list of connections and result sets YAZ-725
211 Avoid yaz_log in sigterm handler for GFS YAZ-737
212 Logging is still performed, but outside sig handler.
214 New ZOOM C feature: result-set caching with memcached. Example:
215 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
217 Remove SSL via OpenSSL support YAZ-732
218 Also deprecate two functions from comstack that aren't working with
219 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
221 Revert "Bison: use %name-prefix directive rather than -p option"
223 --- 5.0.12 2014/01/22
225 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
227 SRU GET/Solr base URLs may hold additional ?args YAZ-729
228 ZOOM option extraArgs already does this, though. It seems useful
229 when dealing with Solr targets to limit by filter, eg.
230 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
232 Remove #fragment for HTTP request encoding YAZ-730
234 Doc: Update list of DLLs/LIBs

240 ZOOM: fix "lost connection" problem with servers that uses both squid
241 and another proxy behind it that returns Location headers with relative
244 zoomsh: do not use readline for stdin (no tty) YAZ-724
245 Just use fgets in that case. If the user hits Ctrl-D a new-line
248 zoomsh: empty command ignored YAZ-723
249 rather than performing exit of zoomsh.
251 yaz-url utility offers option -v to enable verbose mode.
253 yaz_url uses yaz_check_location and offers verbose mode.
255 Add new function yaz_check_location.
256 This function gets an absolute URI from Location (HTTP redirect).
258 cookie API: introduce yaz_cookies_reset
260 Update cql.y for newer bison YAZ-720
261 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
262 longer supported. Instead one must use %lex-param and %parse-param .
264 --- 5.0.10 2014/01/09
266 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
269 rpn2solr: support truncation left(2), left&right(3) YAZ-718
271 Mention SRU version 2.0 in yaz-client man page.
275 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
280 Make cs_parse_host public.A
282 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
283 introduced in YAZ 5.0.6.
287 Fix buffer corruption for yaz-ztest record fetch.
291 Allow yaz-ztest to return user-defined records (one record per file).
292 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
294 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
295 Use the stream write instead of odr_printf which has a 4K tmp buffer.
297 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
301 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
302 can read and write this format. For record format JSON, yaz-ztest returns
303 MARC-in-JSON records.
305 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
306 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
310 Improve error reporting for ICU chains YAZ-707
311 Report config element+rule when ICU status is "failure".
313 ZOOM: stop fetching if present response has no records YAZ-710
314 Some targets return less records than their hit count would suggest.
315 This prevents ZOOM from continuing to fetch records if any present
316 response has 0 records in the response.
318 Ensure that GFS calls exit if any listener fails YAZ-710
319 Before, if XML config was in use, it would start the default
324 yaz-ztest: -V shows version (like yaz-client -V)
326 New iconv encoding: danmarc YAZ-692
328 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
330 daemon: only wait for immediate child rather than all children. YAZ-704
332 yaz-client: fix setting of SRU record schema. If scheme was unset, it
333 could lead to invalid memory reference.
337 yaz-ztest returns schema for MARCXML test records. SRU require that
338 recordSchema for records.
340 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
341 instead of non-surrogate diagnostic. This is a per-record failure.
343 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
344 may refer to multiple listeners now. Attribute listenref is a comma separated
347 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
348 option is given for GFS, the dirname of filename (for -f) is used
349 as prefix for options such as cql2rpn, ccl2rpn, etc.
351 Content-Type charset fixes YAZ-701 . Do not inspect charset in
352 Content-Type header for SOAP when decoding SRU. The payload (XML)
353 itself tells what encoding it is. In response, never supply encoding
354 in Content-Type. The response payload (XML) tells what it is (with no
355 encoding in XML it's UTF-8).
357 HTTP decoding: allow blanks in URL paths YAZ-700
361 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
362 and facets. Ensure recordData and recordSchema are always present in
363 record element, because they are required.
365 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
368 Simplify in a lot of places using odr_strdupn.
370 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
374 Increase various buffers in GFS's statserv_options_block
375 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
376 This change makes many type-casts redundant, and, thus simplifies code.
378 Remove last bits of WAIS support.
380 Remove member 'size' from Odr_oct.
382 Slim down the public part of 'struct odr'. Most elements are not part
383 of struct Odr_private.
385 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
386 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
387 In particular facets are supported in both client - and server side.
388 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
389 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
390 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
391 both request/response). This is what a search handler in the GFS
392 will see (regardless of whether operating in SRU mode or Z39.50).
394 Changes to the srw.h (SRU/Solr) definitions include:
395 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
396 (char*), which replace union query and query_type (int). This is because
397 SRU 2.0 supports a queryType parameter. This also means that, to carry
398 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
399 x-pquery=PQFstring (extention parameter). The extension parameter
401 - New element, packing, that has information about SRU
402 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
404 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
406 New element, packing, in Z_SRW_explainRequest.
408 New elements in Z_SRW_scanRequest, queryType and scanClause.
409 These replace query_type and scanClase untion. This is similar to what
412 --- 4.2.69 2013/10/01
414 GFS: log when closing down - at least SIGTERM YAZ-684
415 Also change formatting WRT PID logging a bit.
417 Improve display of MARC records with multi-byte subfield IDs YAZ-695
418 In some rare cases subfield identifiers are multi-byte characters.
419 This will try to deterime length of those and split accordingly.
420 This affects display in line mode as MARCXML/MarcXchange. The encoding
421 of ISO2709 is the same.
423 Change inp argument to const for yaz_read_UTF8_char.
425 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
427 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
429 Better check of marc leader info YAZ-691
430 Problem is that some systems generate MARCXML/MarcXchange with
431 funny headers. These will not work if encoded as ISO2709.
432 Some tests produce new output, due to updated warning messages
434 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
436 yaz-client: display MAB records YAZ-689.
437 Thanks for Heiko Jansen for this patch.
439 New utility z_get_HTTP_Response_server which allows both HTTP server name
440 and HTTP server URL to be given in response.
442 Debian: do not depend on obs tcl8.3.
444 Debian: do not depend on obs libicu36-dev.
446 --- 4.2.68 2013/09/23
448 GFS: pass additionalSearchInfo to search memeber search_input if
449 given. Otherwise pass otherInfo. Request for facets and other search
450 related things will be passed there in future versions of YAZ.
452 New ZOOM setting, authenticationMode, which allows authentication
453 paramters to be encoded in the URL rather than via HTTP Basic auth.
456 rpn2solr: fix nested AND/OR handling. YAZ-685
458 Add comparison routines for some Z-types, such as NamePlusRecord,
459 RPNQuery, Query, RecordComposition and OtherInformation.
461 --- 4.2.67 2013/09/19
463 Don't decode MAB as MARC. Just like we don't attempt to decode
464 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
466 CCL: allow quoted terms for date ranges. YAZ-681
468 Introduce ccl_parser_qual_search. This function makes old function
469 ccl_qual_search, from YAZ 2, available again.
471 Add yaz_facet_list_to_wrbuf. YAZ-683
473 --- 4.2.66 2013/09/11
475 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
476 schema was given for search. YAZ-675
478 Add Solr date range searches. YAZ-621
480 --- 4.2.65 2013/08/22
482 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
484 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
486 ISO2709/MARC parse most octet aligned records; not just those that
487 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
488 MARC parse more records instead of just dumping as is. YAZ-670
490 ZOOM: proper caching for variations of record schema. YAZ-671
492 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
494 --- 4.2.63 2013/07/17
498 --- 4.2.62 2013/07/11
500 New utility z_get_HTTP_Response_details - an extended version of
503 New utility yaz_url_get_error which returns error message of last
504 failed yaz_url_exec call.
506 yaz-url and url functions: allow max HTTP redirects to be controlled.
508 New functions yaz_file_glob2, yaz_xml_include_glob.
509 These functions takes a flags parameter, which, for now only controls
510 whether to fail inclusion of a non-existing file (without glob
511 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
513 --- 4.2.61 2013/06/20
515 For MARC XML parsing, allow record without leader. A fake/default leader
516 is inserted and a warning is tagged with the record.
518 ICU: fix leak in in icu_iter_get_org_info.
520 --- 4.2.60 2013/06/14
522 ICU: fix bug in icu_iter_get_org_info (un-init variable).
524 --- 4.2.59 2013/06/11
526 Implement z_HTTP_header_remove.
528 --- 4.2.58 2013/06/11
530 ICU: Disallow 0 ptrs for some ICU string utilities.
532 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
533 returns original tokens (before normalization).
535 CCL: avoid z39.58/regex truncation when not needed. Apply only the
536 conversion of those masks, when absolutely necessary.
538 CCL: configurable masking character - @mask. Default masking character
541 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
542 full response anyway, so a Transfer-Encoding header will obstruct the
545 --- 4.2.57 2013/05/15
547 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
548 picking a socket. Problem is that some systems has IPV6 support, but
549 we can't create sockets for them, so we pick AF_UNSPEC first.
551 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
552 use content_len to determine resulting Content-Length in HTTP response
553 and NOT Content-Length supplied in headers by user.
555 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
556 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
558 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
561 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
562 with big endian and unsigned char (by default).
564 --- 4.2.56 2013/04/26
566 Fix yaz-client connect (crash in 4.2.55).
568 --- 4.2.55 2013/04/26
570 Fix proxy/host problem for ZOOM that could occur if unix sockets
573 New Debian package libyaz4-dbg.
575 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
576 differently in tcpip_close.
578 --- 4.2.54 2013/04/17
580 Windows installer of YAZ includes YAZ4J as a component.
582 CQL: allow "extra terms" again, by default. Thus, the CQL parser
583 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
584 and earlier. CQL parser may operate in strict mode where queries
585 not conforming to the standard BNF are rejected (syntax error).
586 Whether the CQL parser operates in strict mode is controlled with
587 cql_parser_strict . Strict mode enabled with option -S for utilities
588 cql2pqf and cql2xcql .
590 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
592 --- 4.2.53 2013/04/10
594 New charset, MARC-8c, which is like MARC-8 but allows control characters
595 0x01 through 0x1F, except ESC to be passed through verbatim.
597 Fix a problem with duplicate sub field character in MARC output. Problem
598 happened only when output was MARC-8 encoded.
600 --- 4.2.52 2013/04/03
602 yaz-ztest: Use hash for fake hit count. Before, random number was used.
603 This is problematic for unit tests using yaz-ztest. This patch also makes
604 a hash for CQL queries. For RPN, any term with a leading digit will be
605 treated as pseudu hit count (to force any particular hit count by a client).
607 yaz-ztest: return unique MARC dummy records. Beyond record offset
608 24, the author surname is patched with offset to make all records
611 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
612 on system wide default (/proc/sys/net/ipv6/bindv6only).
613 @4 binds to IPV4 only. @6 binds to IPV6 only.
615 Update CQL API documentation a bit
617 CQL: don't accept extra terms for queries. Makes the CQL parser
618 stricly conformant to the standard.
620 --- 4.2.51 2013/02/12
622 GFS: scan handler gets extra_args from request and may return extra
623 response data . That's for SRU only.
625 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
627 --- 4.2.50 2013/01/30
629 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
631 OPACXML: sync spelling of availabilityDate in XML to that of Schema
632 opaxxml.xsd. The schema had the correct spelling of this member always.
633 The ASN.1 was mis-spelled and still is (API change) - we are
634 not changing this. However, the OPAC to XML conversion had yet
637 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
640 New function, z_ext_record_oid_nmem, which is similar to
641 z_ext_record_oid but takes NMEM rather than ODR
643 --- 4.2.49 2013/01/18
645 ICU: New conversion element 'join' which joins tokens into one
646 with a custom character given by rule attribute.
648 --- 4.2.48 2013/01/10
650 New GFS search member: present_number. This is a hint to the
651 search handler how many records are going to be fetched immediately
652 following search. There's no guarantee that it's going to be the case,
653 since it depends on hit count (for Z39.50 piggyback) and whether errors
656 Make a few functions static (private). The functions getbyte_stream,
657 ungetbyte_stream and yaz_gets are now private. They were never declared
660 yaz-marcdump: exit(5) for serious decoding errors
662 ISO2709 decoding: be more picky WRT header
664 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
665 was only used as to indicate that next-result-set-position should be
667 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
668 Based on patch from Ashley Sanders.
670 Make some functions static/private in PQF parsing. Those functions were
671 never declared in a public header and so should not be in use by
672 applications based on YAZ.
674 --- 4.2.47 2012/11/23
676 ZOOM: special options to control APDU logging.
677 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
678 logging of APDUs until "saveAPDU" option is set again. If logging is
679 already enabled the effect is that current APDU buffer is cleared.
680 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
681 logging (default behavior on new connection).
682 The APDUs sent/received can be obtained by using
683 Using ZOOM_connection_option_get(c, "APDU") or
684 ZOOM_connection_option_getl(c, "APDU", &l).
686 GFS: relay implementation_version from backend
687 From 3.0.40 and later, implementation_version from backend was
688 not used in init response at all.
690 --- 4.2.46 2012/11/15
692 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
693 mode at all. Probably never did.
695 Make a new version of ztest.pem that, at least, is not expired.
697 --- 4.2.45 2012/11/13
699 Fix description of CCL directive 'case'.
701 More tight checking of form arguments (yaz_uri_to_array). Makes
702 YAZ better at rejecting big and/or bad POSTs.
704 SRU decoding does not report more than up to 10 invalid arguments.
706 rpn2cql: less quotes in generated terms. Semantics unchanged, but
707 it's prettier this way.
709 --- 4.2.44 2012/10/25
711 New utility yaz_decode_init_diag. Defined in proto.h.
713 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
714 given for unix local socket.
715 The COMSTACK string for doing so is:
718 unix:/myfile:tcp:localhost:9999/mybase
719 unix:/myfile:localhost:9999/mybase
720 unix:/myfile:http://fakehost/mybase
722 debian: Use dpkg-buildflags in build process.
724 --- 4.2.43 2012/10/19
726 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
727 global's SRU service uses a recordPosition scheme starting from zero.
728 First record's position should be one
729 according to the standard.
731 --- 4.2.42 2012/10/18
733 Allow more namespaces for SRU. This is to allow, for example, an
734 incorrect namespace returned from server
735 http://services.igi-global.com/sru .
737 Minor fixes for compilation on Windows.
739 --- 4.2.41 2012/10/11
741 daemon: log total number of bad signals from child on stop so that it
742 is more easy to spot problems with child worker processes.
744 retrieval: empty backend name attribute omits element set
745 from being used in retrieval.
747 --- 4.2.40 2012/10/04
749 Implement Solr sort strategy "solr", similar to sru11 sorting.
750 This will implement the correct parameters on Solr requst to do
753 --- 4.2.39 2012/09/28
755 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
758 MARC: Extra/missing indicator handled for MARCXML.
759 The indicator length is given in header and is the same for the
760 whole record. If attributes ind1, ind2 are missing, then content
761 character defaults to blank. Extra indicator attributes (beyond)
762 indicator length are treated as an error.
764 Reformat: delete trailing whitespace
766 --- 4.2.38 2012/09/17
768 MARC: fix non-ASCII characters for leader. This is to ensure we can
769 generate XML in UTF-8.
771 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
772 in one node with structure word.
774 --- 4.2.37 2012/09/04
776 yaz-json-parse: JSON output may be pretty printed by using option
779 Increase default value of max message for Z39.50 Init for GFS, ZOOM
780 and yaz-client. Old value was 1 MB. New value is 64 MB.
782 --- 4.2.36 2012/08/22
784 yaz-client: don't display bogus records from SRU servers. Some SRU servers
785 return more records than given by *maximumRecords*. Skipping those in
788 record_render: simplify buffer return handling and fix at least one bad
789 memory reference, that broke the test_embed_record sometimes.
791 Allow http://user:pass@host notation for yaz_url_exec.
793 zoomsh: allow shell command to be executed. Via the system(3) call.
795 yaz_poll: Allow num_fds == 0
797 yaz-client: fix bad encoding of "itemorder item". The itemorder
798 item <no> - command forgot to use length of encoded Item Request
799 package. Error present since YAZ 3.
801 yaz-ztest: fix bad usage of session handle. Bug was introduced when
802 result sets were saved (271a9c83).
804 SRU recordPacking: guess record packing in response rather than looking
805 at the recordPacking element which, OF COURSE, changed semantics in SRU
808 Decode SRU 2.0 responses. The official namespace for responses, according
809 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
810 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
811 nature.com's server, however, usee namespace
812 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
813 we are now using a glob-expr to match up the namespace. ZOOM C and
814 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
815 I can not find a single real example showing the "real" namespace in
816 the documentation from OASIS. The namespace for requests is different
817 from responses, but this is not added to YAZ yet, when we don't encode
820 --- 4.2.35 2012/06/26
822 zoom/record_render: add support for Base64 decoding fo MARC records
823 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
824 which will decode base64 + ISO2709 marc-8 encoded material from text node
827 --- 4.2.34 2012/06/07
829 Add missing definitions ZOOM_resultset_get_facet_field_by_index
830 and ZOOM_resultset_facets_names.
832 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
835 Change APDU dump printing to avoid long leading blanks. For levels 16
836 or larger the level is shown and the indentation is truncated but
837 recursed with modula 8. This makes it still reasonable easy to read
838 - even for nested BER dumps.
840 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
841 return 0 (incomplete package) in case where the BER package was
842 considered too nested (return value of -2).
844 dumpber: lines of level 15 are not indented further. Two spaces per
845 indentation; indentation 15 or more is indented to a fixed indentation
846 and augmented with a level=<no> indication.
848 zoomsh: increase max size of command+args
850 GFS: No limit in RPN buf size in CQL to RPN conversion.
852 --- 4.2.33 2012/05/09
854 New function for daemon utility, yaz_daemon_stop .
856 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
858 --- 4.2.32 2012/04/25
860 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
861 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
863 --- 4.2.31 2012/04/23
865 YAZ daemon utility relays SIGUSR1 to child process.
867 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
868 would result in en empty database list - which in turn would result in
869 encoding failure for search.
871 Fix reading beyond string in yaz_sort_spec.
873 --- 4.2.30 2012/04/11
875 Add two new SRU diagnostics:
876 236: Access to specified database denied
877 1015: Init/AC: Maximum number of simultaneous sessions for Userid
879 Document the very useful ZOOM-C option "apdulog".
881 CQL to RPN: term may be passed through verbatim. This is enabled with
882 truncation.cql . The assumption being that the term is already CQL.
884 --- 4.2.29 2012/03/20
886 record_conv: leader spec may be given for marc element.
887 The leader spec is given as attribute leaderspec for element marc.
888 For example to convert a MARC21 record from MARC-8 to UTF-8:
889 <marc inputformat="marc" outputformat="marc"
890 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
892 record_conv: allow user-XSLT params. For example:
893 <xslt stylesheet="MARC21slim2DC.xsl">
894 <param name="myparameter" value="myvalue"/>
895 <param name="otherparameter" value="othervalue"/>
898 record_conv: fix error handling for missing marc charsets.
900 CQL: fix extra terms in wrong order.
902 --- 4.2.28 2012/03/06
904 record_conv: modify new API for conversion types. The conversion types
905 may be passed in new functions yaz_record_conv_configure_t and
906 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
908 Avoid mixed statement/variable declare; fixes compilation with Visual
911 --- 4.2.27 2012/02/28
913 Add non-standard SRU diagnostic: 235: "Database does not exist".
914 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
915 Update SRU to Bib-1 diagnostic maps accordingly.
917 CCL: add two new diagnostics for unsupported masking. The new
918 diagnostics are: "Embedded truncation not supported" and
919 "Single charcacter mask not supported".
921 --- 4.2.26 2012/02/23
923 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
925 --- 4.2.25 2012/01/11
927 Build YAZ for Ubuntu Oneiric.
929 CCL: allow parantheses for proximity operands. For example CCL query
930 (a) % (b) is now allowed.
932 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
933 marked dead, rather then being destroyed. If not, the session memory is
934 being free'd before the search/scan handler is finished. Also destroy
935 'request' memory in request_release rather than in various places,
936 which resulted in leaks from time to time.
938 --- 4.2.24 2011/12/21
940 cql_sortby_to_sortkeys: honor sort prefix.
942 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
943 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
944 The rpn2cql family of functions now always returns quoted CQL terms.
946 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
948 --- 4.2.23 2011/12/15
950 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
951 sequence is treated as one. For example, &&a=b&&&c& is identical to
954 --- 4.2.22 2011/12/05
956 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
957 APDUs for a connection to a WRBUF.
959 --- 4.2.21 2011/11/23
961 Fix cql_sortby_to_sortkeys. Completely broken before.
963 Make CCL's @truncation work again.
965 --- 4.2.20 2011/11/09
967 New ZOOM connection setting: tproxy. It's like proxy, but does not
968 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
969 to set resolved address + port for a connection outside ZOOM itself.
971 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
973 --- 4.2.19 2011/11/07
975 Fix uninitialized variable in Solr spell support (could cause SEGV
976 for SRU response decoding).
978 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
979 back-end's addinfo through into the ZOOM response addinfo.
981 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
982 they are separated by a colon and a space rather than simply
985 --- 4.2.18 2011/10/28
987 Add support for Solr spell-checking/suggestions through ZOOM.
988 If a Solr target has been configured correctly for spelling-checking
989 and suggestions, these will now be returned on the ResultSet option
990 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
992 --- 4.2.17 2011/09/28
994 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
995 with a flag whether to substitute escape sequences or not.
997 --- 4.2.16 2011/09/22
999 Fix nmem_strsplit_escape to substitute escape char properly.
1001 New option for zoomsh -e , which makes it abort on first error and
1002 return process exit code to indicate success/failure.
1004 YAZ options utility supports special option -- which makes all it treat
1005 all following arguments as non-options.
1007 --- 4.2.15 2011/09/16
1009 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1010 searched if absolute filename is given.
1012 Fix conv_xslt() error-reporting when stylesheet is not found.
1013 (The value of fullpath is meaningless in this situation.)
1015 --- 4.2.14 2011/09/07
1017 Fix problem in CQL sort node creation: un-initialized memory.
1019 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1020 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1021 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1024 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1025 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1027 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1028 will make it possible to use both single-character mask (#) and wildcard (?)
1029 in CCL . Throw diagnostic for left truncation because that is not supported
1032 --- 4.2.13 2011/09/01
1034 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1035 cases using escapes (\-sequences) and masking.
1037 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1038 would result in a read one byte beyond string.
1040 rpn2ccl may use Z39.50 masking for terms (t=z).
1042 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1044 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1045 not --cppflags (which seeems like an error in icu-config).
1047 --- 4.2.12 2011/08/27 RPM package only
1049 cql2ccl: fix conversion of terms: operator characters were not
1052 --- 4.2.11 2011/08/25 RPM package only
1054 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1055 CCL parser will map both # and ? to their regular expression
1056 quivalents (. and .*).
1058 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1059 of reserved CQL characters.
1061 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1062 is, so that they are passed through.
1064 --- 4.2.10 2011/08/24
1066 ZOOM SRU mode: more aggressive re-connect.
1068 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1069 made available as a utility function, declared in <yaz/logrpn.h>
1071 rpn2cql_structure() supports proximity nodes (except that the Type-1
1072 proximity node's "exclusion" binary is ignored, as there is no way to
1073 express that in CQL). Fixes bug #4564.
1075 --- 4.2.9 2011/08/18
1077 Fix SEGV that could occur if set command of zoomsh was given without
1078 value (2nd argument).
1080 Fix SEGV that could occur if unsupported transport was given for
1081 COMSTACK - say https (when SSL was unavailable).
1083 Build yaz-url on Windows too.
1085 --- 4.2.8 2011/08/11
1087 New utility to get web content. Header is url.h. A command line tool
1088 yaz-url is part of the distribution and packages.
1090 Fixes for SSL COMSTACK (when gnutls is in use).
1092 New functions yaz_base64{encode,decode}. Header is base64.h.
1094 --- 4.2.7 2011/08/03
1096 ZOOM C includes HTTP response buffer as additional info if it fails
1097 to decode the SRU response.
1099 Make wrbuf_json_puts available.
1101 --- 4.2.6 2011/07/28
1103 zoom: throw diagnostic for invalid value for option "sru". Before a
1104 bad SRU request was sent.
1106 Adding new utility wrbuf_vp_puts.
1108 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1110 --- 4.2.5 2011/07/21
1112 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1113 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1114 redirect was used at the same time.
1116 MARC line mode decoding: be less picky about length given - first
1117 5 digits of header that is.
1119 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1121 Changes to decoding of SRU records: a record with recordPacking=xml is
1122 modified with a new root element <yaz_record> if the recordData contains
1123 multiple children elements. This is to make the record XML parseable
1126 RPN to Solr conversion: encode special characters.
1128 Generic Frontend Server: fix uinitialized member, stepSize.
1130 --- 4.2.4 2011/06/21
1132 Fix a bug in SRU decoding of records.. The database records stored
1133 had un-initialized memory, but it would only be seen with yaz_record_render
1134 and type_spec="ext" .
1136 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1138 --- 4.2.3 2011/06/17
1140 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1142 --- 4.2.2 2011/06/10
1144 Add new utilities to convert from CQL to CCL . These utilities have
1145 prefix cql_to_ccl defined in cql.h.
1147 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1148 lead to memory heap corruptions when ICU utilities were in use.
1150 --- 4.2.1 2011/06/07
1152 Make compilation work without Libxml2.
1154 yaz-client: remove redundant blanks in display of searchResult-1 term
1157 --- 4.2.0 2011/05/18
1159 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1160 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1162 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1163 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1164 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1165 Note that the CQL sortby spec is only converted when the GFS is already
1166 converting from CQL to RPN (cql2rpn element).
1168 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1169 specify whether to collapse delimitors or not. The existing nmem_strsplit
1170 do collapse (collapse parameter = 1).
1172 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1174 Rename internal func yaz_use_attribute_create. While non-static, this
1175 function is not declared in a public header.
1177 --- 4.1.7 2011/03/15
1179 Add -lCrun when linking with ICU on Solaris.
1181 More quicks character set conversions for OPAC records.
1183 --- 4.1.6 2011/03/10
1185 fix problem with record_render: records were converted (character set
1186 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1188 --- 4.1.5 2011/03/08
1190 SRU: add methods for handling DADS SRU-proxy facets.
1192 Separate OPAC record character set for ZOOM_record. yaz_record_render
1193 allows a character set given as charset=from/opacfrom,to where 'from' is
1194 the character set of a bibliographic record, 'opacfrom' is character set
1195 of OPAC record and 'to' is the target character set.
1197 --- 4.1.4 2011/02/21
1199 yaz-client: show may XML format records. Command show followed by 'format'
1200 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1203 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1206 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1208 --- 4.1.3 2011/01/27
1209 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1211 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1212 this package can be distinguished from other vendors.
1214 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1215 as determined by configure
1217 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1219 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1220 returns no error and no record, the present request is considered
1221 partial (only a subset of the records could be returned by backend), and
1222 so it is appropriate to set Present Status to partial-4.
1224 --- 4.1.2 2010/11/02
1226 Move yaz-config man pages to section 1.
1228 More documentation about Solr.
1230 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1231 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1232 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1233 peers on some Linux systems. However, in general that does not work
1234 so YAZ can not rely on that to work. Debian changed behavior in this
1235 respect from Debian lenny to Debian squeeze (still testing as of Oct
1237 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1239 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1241 --- 4.1.1 2010/10/05
1243 Fix yaz-config output: echo_source not set correctly by configure.
1245 --- 4.1.0 2010/10/05
1247 Solr Web Service support for yaz-client and ZOOM.
1249 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1251 --- 4.0.12 2010/08/17
1253 Z39.50 facet support. Facet specifications are passed for search in
1254 other-information with ASN.1 as defined in facet.asn and OID
1255 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1256 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1257 3 is limit (number of entries to get in response). yaz-ztest returns
1258 dummy facets if a client asks for them.
1260 --- 4.0.11 2010/07/09
1262 CCL fixes: bug 2895 and bug 3539.
1264 GR1-display: add comma in display - was removed by mistake in
1267 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1269 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1271 --- 4.0.10 2010/06/18
1273 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1274 result set from a connection. The result set will be on its own
1275 thereafter; no operations on it will perform retrievals from a target.
1276 Only cached copies are returned.
1278 ZOOM C:fix case for HTTP servers responding with Connection:close.
1279 Ensure that if there is a current task it is resumed (like fetching
1280 more records in a result set) . Bug #3484.
1282 PQF parser: use odr_atoi for Odr_int (not atoi)
1284 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1285 values that contain any non-digits are treated as string attributes
1286 (previously decoding only checked for leading character ([0-9]). PQF
1287 encoding: attribute string values are not surrounded by double-quotes.
1289 --- 4.0.9 2010/05/21
1291 New utility for managing threads - thread_create.h.
1293 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1294 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1295 but YAZ' implementation do.
1297 Fixes for yaz_cond-functions on Windows 7.
1299 DLL export more symbols.
1301 zoomsh: show record do NOT render opac.
1303 Remove *.la files from Debian and RPM packages.
1305 --- 4.0.8 2010/05/11
1307 Debian package libyaz-dev depends on libgnutls-dev again (was
1308 removed in YAZ 4.0.6, but due to Libtool it is still needed
1309 even though yaz-config do not list libgnutls libs).
1311 ZOOM: Use only one WRBUF for returning string results for
1312 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1314 ZOOM: ZOOM_connection do not use a shared pointer to
1315 ZOOM_resultset after ZOOM_resultset is destructed by
1316 user. Reverts to YAZ 4.0.4 behavior.
1318 --- 4.0.7 2010/05/04
1320 record-conv: fix problem with at least one XSL conversion -
1321 due to probably incorrect usage of XML XSL documents.
1323 --- 4.0.6 2010/04/29
1325 Fix yaz-config for static mode and the use of SSL (gnutls).
1327 --- 4.0.5 2010/04/29
1329 Forward decl timeval struct in mutex.h and gettimeofday.h.
1331 yaz-config: fix 'static' mode linking.
1333 --- 4.0.4 2010/04/28
1335 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1336 are wrappers for pthreads or Windows. For Windows these are put in
1337 a separate DLL: yaz_cond4.
1339 libyaz.la (whole source) is compiled with thread. If thread support
1340 is enabled enabled, all source of YAZ is compiled with treading support.
1341 This allows core utilities such as yaz_log to use thread facilities.
1342 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1343 thread utilities. This commit moves mutex utilities (mutex.c) from
1344 libyaz_server.la to libyaz.la.
1346 yaz-json-parse displays leading text until error.
1348 --- 4.0.3 2010/04/09
1350 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1351 patch from Giannis Kosmas.
1353 SRU: no longer URL encode SRU database. The URL for an SRU server is
1354 a URL and such is alreeady encoded - at least when given with leading
1355 http:// or https://. This reverts behavior to YAZ 3.0.50.
1357 Support for new MARC XML notation TurboMARC which like MARCXML is a
1358 complete representation of MARC/ISO2709.. This one, however, is more
1359 compact and allows for faster processing with XSLT. TurboMARC can be
1360 used in the marcdisp.h API, from the yaz-marcdump utility and from
1363 yaz-ztest can be configured - via the database - to perform certain
1364 delays when it performs operations search, present and single record
1365 fetch. This allows testers to make yaz-ztest act as a real or even slow
1366 Z39.50 server. Refer to the yaz-ztest man pages for details.
1368 --- 4.0.2 2010/03/09
1370 wrbuf_destroy allows NULL WRBUF passed to it.
1372 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1374 Add ZOOM_connection_close.
1376 No fixed size buffers for ZOOM shell - bug #3257.
1378 tstodr: make it work on s390 platform.
1380 New icu iterator-functions. The new icu_iter-functions makes it possible
1381 to use ICU chains from many threads.
1383 yaz-client: better syntax check for show command.
1385 --- 4.0.1 2010/01/26
1387 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1390 New simple local-file XML include facility which allows file glob-patterns.
1391 Refer to yaz/xml_include.h.
1393 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1396 ZOOM_record_get supports new parameter "format" which makes it format XML
1399 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1400 JSONText in ECMA-262) is JSONValue, not JSONObject.
1402 --- 4.0.0 2010/01/20
1404 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1405 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1407 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1408 POSIX/Unix builds .so with major version 4.
1410 Remove old LOG_-defines from log.h. They have been obsolete and
1411 undefined by default for the last 5 years.
1413 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1415 GFS: Remove socket (int *fd) from search_rr handler. The socket
1416 descriptor ptr is a facility that allowed a search handler to supply
1417 a socket which would serve as a callback - when search was complete.
1418 This facility has now been in use for years.
1420 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1421 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1422 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1423 returns 'const char *' rather than 'char *. The returned string is
1424 read-only and should not be modified by applications. COMSTACK cs_close is
1425 now a void function - it no longer returns int. No applications check for
1426 the value and the implementations has always returned 0.
1428 ZOOM: use size_t for scan hit counts and str size. Functions
1429 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1430 occ (hit count) and len (string length) are now of type size_t pointer
1431 rather than int pointer. This is to be able to represent large hit counts
1432 and to also just to use the proper type for string length (strlen result).
1434 New JSON parser. Refer to include/yaz/json.h .
1436 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1437 Used to be int in some cases. Many wrbuf_-functions used to return an int
1438 indicating some length.. These return values were never used. And so they
1441 ODR: odr_malloc, odr_total now takes size_t for size.
1443 clone_z_type: fix leak; occurred for encoding failures.
1445 --- 3.0.52 2009/12/03
1447 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1448 bug was introduced in 3.0.51.
1450 --- 3.0.51 2009/12/02
1452 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1454 tcpip comstack: fix leak for getaddrinfo.
1456 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1457 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1458 Decoding of SRU "path" database is performed by private function
1459 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1460 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1462 yaz-client: honor base command for SRU. Change when database setting
1463 is applied for SRU and ensure it is kept when a connection is reset.
1464 Change also the way errors are displayed or SRU (decoding of packages).
1466 --- 3.0.50 2009/11/02
1468 Add support for extra request / response data for SRU codecs and GFS.
1469 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1470 for extra data response buffer and length. For the GFS, both request
1471 and response data (XML) is carried in extra_args and extra_response_data
1472 for the search handler. Patch by Ko van der Sloot.
1474 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1475 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1476 10010). This fixes bug #2113.
1478 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1479 cmdfile included a 'quit' command that would result in a memory violation.
1481 --- 3.0.49 2009/10/01
1483 Make a number of functions defined in xmlquery.c static. These have
1484 never been declared in a public header file (yaz/xmlquery.h) and was
1485 made public by mistake.
1487 Improve speed of character conversions (iconv utilities). This makes
1488 conversions from MARC-8 faster.
1490 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1491 unless type desired is "raw". This will prevent type "xml" from
1492 returning ISO2709 .. Which obviously can not be XML parsed.
1494 Fix memory leak in ZOOM that would occur if option apdulog was used
1495 on a re-used connection.
1497 Frontend server logs HTTP requests.
1499 Frontend server now sends Z39.50 close when it times out (sesssion has
1500 been idle for too long). Versions 2.0.30 and earlier also sent close.
1501 But due to a mistake this was disabled in all versions after that, i.e.
1502 the server would just close the socket immediately.
1504 yaz-client emits a better message when receiving an unrecognised
1505 userInformationField.
1507 Skip zero-length subfields when decoding ISO2709. This rare case happens
1508 if a record has two FS characters in a sequence. Without this patch
1509 there would be a reference beyond char array in using_code_len fragments
1512 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1514 --- 3.0.48 2009/08/28
1516 The show command offered by the zoomsh command now takes a 3d optional
1517 parameter type which is what is passed to ZOOM_record. If the type
1518 argument is omitted, "render" is used.
1520 RPN to CQL conv may use USE string attributes (bug #2978).
1522 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1524 --- 3.0.47 2009/07/08
1526 Function yaz_xml2query allows a diagnostic element in the PQF XML
1527 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1528 code and additional info respectively.
1530 The BER BOOLEAN is now the integral type Odr_bool which still happens
1531 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1532 typedef'd to Odr_int. This is still an integral 'int', but it may be
1533 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1534 ASN-1 compiler as well as programs has been updated to use the new types.
1536 --- 3.0.46 2009/06/08
1538 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1539 only the bibliographic record was rendered. For type=opac, an OPAC
1540 record is only returned if it is present.
1542 iconv: small fix for encoding of advancegreek.
1544 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1546 yaz-client: option auto_reconnect=on really reconnects.
1548 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1550 server: avoid null ptr ref for for yaz_poll errors.
1552 build: fix RPM build for RHEL 5.3.
1554 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1556 --- 3.0.45 2009/03/31
1558 Fixed bug #2709: TCP connect returns Invalid argument.
1560 Fixed compilation for mingw.
1562 Honor charset for raw records (ZOOM_record_get).
1564 Fixed use of errno for threaded mode that was seen on Solaris 10.
1566 Fixed argument passing with blanks in value for Windows Service.
1568 Disable YAZ' own log rotate by default (no 1 GB limit).
1569 The variable l_max_size which specifies the log file limit is set to 0
1570 (DISABLED): This is due to the fact that YAZ is most often deployed using
1571 logrotate. Also YAZ can not perform log rotate because of unsufficient
1572 permissions (setuid).
1574 --- 3.0.44 2009/02/17
1576 List supported encodings in man page for yaz-iconv.
1578 Fixed missing SSL libs for --libs output
1580 Re-established OID record syntax application-xml. Nobody should use it
1581 but we don't want to change soname because of this symbol being absent.
1583 --- 3.0.42 2009/02/02
1585 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1587 Added member named_result_sets for init handler struct for the GFS. This
1588 allows a server to disable named result sets.
1590 Removed OID record syntax application-xml.
1592 Added support for rule-based transliterator for ICU wrapper of YAZ.
1594 Fixed bug #1902: yaz-icu XML output.
1596 Make YAZ checks Emacs friendly.
1598 BITSTRING value shows value. Bug #2346.
1600 ISO2709 decoding: skip control characters from indicator data.
1602 Omit sort key by default in yaz-icu's output.
1604 Allow combined single char options (again) for YAZ' options function.
1606 Utility yaz-marcdump got option to display YAZ version (-V).
1608 Allow YAZ to use ICU 3.4.
1610 Added new ICU test case which illustrates removal of diacritics.
1612 --- 3.0.41 2008/12/29
1614 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1616 --- 3.0.40 2008/12/29
1618 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1621 Fixed bug #2352: yaz-marcdump crashes for certain record.
1623 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1625 Added support for Danmarc2 to UTF-8 conversion.
1627 Added support for ISO5426 to UTF-8 conversion.
1629 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1630 implementation version.
1632 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1634 --- 3.0.38 2008/11/10
1636 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1637 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1639 ZOOM C now interprets databaseName option for ZOOM connection as path
1642 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1644 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1646 Dummy Libxml2 types no longer defined in headers of YAZ'.
1648 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1651 --- 3.0.36 2008/09/26
1653 Various ODR chapter fixes.
1655 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1657 Added missing source for Windows compilation, mutex.c.
1659 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1661 For SRU connections in ZOOM all records up to "count" are now fetched.
1663 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1664 in Windows due to bad error handling for Libxml2.
1666 Added facility for sending arbitrary records (ASN.1 any) using
1667 ZOOM C's Extended service update. Patch by Sam Reynolds.
1669 New options for ZOOM C's connection, logapdu which makes ZOOM log
1672 --- 3.0.34 2008/06/18
1674 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1676 --- 3.0.32 2008/06/12
1678 Fixed memory violation that could occur when decoding UTF-8. This bug
1679 was only present in 3.0.30 of YAZ.
1681 --- 3.0.30 2008/06/06
1683 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1684 GNU TLS is used by default (if found).
1686 yaz-ztest returns OPAC records if a client asks for OPAC.
1688 Improved speed of MARC-8 encoding.
1690 Added support for lossy and loss-less MARC-8 encoding.
1692 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1694 Added new Windows Service wrapper (sc).
1696 yaz-client's itemorder command may now send a file.
1698 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1700 Added new function yaz_log_xml_errors.
1702 Allow (but warn) unknown XML attributes in MARCXML parsing.
1704 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1706 The UTF-8 to MARC-8 conversion now uses a different set of characters
1707 for Greek symbols. Bug #2120.
1709 --- 3.0.26 2008/02/21
1711 Added yaz_daemon (daemon.h).
1713 Fixed bug #2068: pkg-config trouble
1715 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1717 --- 3.0.24 2008/01/28
1719 Document --with-xml2 option.
1721 Added OPAC XML XSD (etc/opacxml.xsd).
1723 Allow glob mask for name attribute in retrieval element for the
1724 generic frontend server's retrieval facility.
1726 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1727 except POLLIN/POLLOUT.
1729 Fixed error handling in cs_listen. Bug #2037.
1731 --- 3.0.22 2008/01/20
1733 Fixed version in yaz/yaz-version.h.
1735 Fixed bug #2027: Crash when closing connection.
1737 Changed configure so that ICU support is only enabled if only ICU
1738 and Libxml2 is available (because the ICU chain is XML based).
1740 --- 3.0.20 2008/01/15
1742 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1743 is built. Only this DLL depends on the ICU runtime.
1745 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1746 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1748 Changed license of CCL module to 'Revised BSD'. After consultation with
1749 remaining members of the original EUROPAGATE consortium, we are re-issuing
1750 the CCL module without a separate license. The software was developed by
1751 Index Data as part of a research project. The special license was included
1752 to help feed usage information back to the project consortium to support
1753 project evaluation. At this time, the project consortium has long-since
1754 disbanded, and the majority of the original principals have retired. At the
1755 same time, we have significantly modified the software during the following
1756 years, to the point where very practically no original code remains. To
1757 simplify re-use of the software, we have contacted those members of the
1758 consortium who could be reached, and agreed to re-issue the module as a
1759 proper part of the YAZ package.
1761 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1763 CQL closer to being version 1.2 compliant. CQL also allows free-form
1764 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1767 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1768 bug could make Extended services handling crash in the ZOOM layer. This
1769 bug was only present in YAZ 3.0.18.
1771 --- 3.0.18 2007/12/19
1773 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1776 yaz-marcdump reads and writes collection wrapped records.
1778 Handle OPAC for record conversion module.
1780 Fixes for ICU wrapper.
1782 Allow ICU libs to be controlled with --with-icu .
1784 --- 3.0.16 2007/11/12
1786 Added yaz_poll which is a wrapper for select/poll. When poll is available
1787 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1788 sockets to be in use.
1790 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1791 functionality through an XML based configuration (ICU chain). This system
1792 is useful for search facilities such as Pazpar2 and Zebra that needs to
1793 perform tokenization of indexed material. The ICU code in a separate
1794 library libyaz3_icu.a.
1796 Added HTTP tunnel facility for COMSTACK, bug #1752.
1797 This is a facility that allows a Web proxy, such as squid, to tunnel
1798 Z39.50 traffic. This facility is "transparent" to must applications
1799 using YAZ. It's enabled by using pseudo transport connect: followed by
1800 the proxy address, followed by command, then follwed by he regular
1801 "virtual" addresss. For example,
1802 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1804 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1806 --- 3.0.14 2007/09/21
1808 Fixed bad memory reference in ZOOM_record - cuased by member not being
1809 initialized. This was a problem only in YAZ 3.0.12.
1811 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1812 fields were not removed.
1814 Changed the way C code is generated from codetables.xml. Made a MARC-8
1815 conversion trie for each characterSet section rather than codeTable.
1816 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1817 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1819 --- 3.0.12 2007/09/12
1821 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1822 from ZOOM_record_error).
1824 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1826 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1828 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1830 Better SRW-to-Bib-1 diagnostic mapping.
1832 ZOOM C and yaz-client announces SRU version 1.2 by default.
1834 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1837 Fixed in yaz_sru_decode to allow other version than 1.1.
1839 --- 3.0.10 2007/08/22
1841 Added support for SRU scan for ZOOM.
1843 Added support for the use of the older versions or Extended Service
1844 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1845 set to the version , 1=first, 2=second, 3=third. The third version is
1846 what ZOOM C has used so far. And that, obviously, is the default.
1848 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1849 therefore in Zebra and in SimpleServer-based applications). The new
1850 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1851 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1852 which is passed into the back-end search callback function.
1854 Added support for HTTP Basic authentication in clients: the SRU/W
1855 codec encodes the username/password elements of the PDU structure
1856 appropriately, and these may be set using the "user" and "password"
1857 options in ZOOM-C applications (the same options that are used for
1858 Z39.50 authentication).
1860 --- 3.0.8 2007/06/25
1862 Fixed bug #1208: SSL appears to be broken in ZOOM.
1864 Fixed bug #1206: Libxml2 include path weirdness.
1866 Added oid_name_to_dotstring.
1868 Allow elementSetName to be specified for ZOOM C record update.
1870 Allow waitAction to be specified for ZOOM C based for Extended Services.
1872 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1873 syntax OID. Bug introduced in YAZ 3 series.
1875 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1877 --- 3.0.6 2007/06/06
1879 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1880 directory. yaz-client now reads commands from file given by option -f
1881 if specified; then tries to read .yazclientrc in current directory.
1882 Failing that, it reads .yazclientrc from user's home directory.
1884 Added support for correlationInfo Note and ID for Record Update via
1887 Added yaz-client command querycharset which specifies character set for
1888 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1889 (termListAndStartPoint).
1891 Charset ISO5428:1984 is an alias for ISO5428-1984.
1893 Implemented a way to perform scan in a result set using Z39.50. This
1894 is achieved by attaching the result set name in the characterInfo
1895 (type InternationalString) of OtherInformation in the Scan Request PDU.
1896 The result set is identified in the otherinformation by the new OID:
1897 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1898 This allows for scan in result set and faceted search . Zebra did some
1899 of this in the APT term using attribute type 8 and value being result
1900 set. Using the OtherInformation approach for this is cleaner and easier
1901 to work with in proxies and the like. This facility can be used in
1902 yaz-client using new command setscan which takes a result set as first
1903 argument, start position (APT) as second.
1905 Changed decoding of SRU XML packed records to deal with servers that
1906 have recordData with XML data with multiple root nodes. Also make
1907 comparison for recordPacking case insensitive. Again, one server
1908 returns "XML" where others return "xml".
1910 For SRU responses allow Content-Type application/xml as well as text/xml.
1912 --- 3.0.4 2007/05/21
1914 Fixed bug in character set conversion of BER strings. Bug introduced
1917 --- 3.0.2 2007/05/08
1919 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1921 For OID class, use oid_class consistently.
1923 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1926 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1927 character set for bibliographic information interchange". By Giannis Kosmas.
1929 Added documentation on new OID API.
1931 --- 3.0.0 2007/05/02
1933 Changes to generic frontend server interface: added new member
1934 'query_charset' for bend_initrequest structure. A backend init handler
1935 should set this member to its native character set for query terms.
1936 When defined, the frontend server logic will announce this character set
1937 to a client if the negotiationModel bit is set by the client. All server
1938 implementors are encouraged to specify this. If a backend server does not
1939 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1941 Added CCL utility to remove terms (stop words) from resulting RPN
1942 tree. This is handled by functions with prefix ccl_stop_words_ .
1944 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1945 terms in RPN queries.
1947 Clean-up the CCL API. Moved some internal structures from ccl.h to
1948 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1949 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1950 This is replaced by ccl_parser_find_str which takes a string instead.
1952 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1953 libyaz.la is the core of YAZ except the generic frontend server and
1954 does not depend on POSIX threads anymore. libyaz_server.la is the
1955 generic frontend server facilities and uses POSIX thread functionality
1956 if available. The libyaz.la no longer depends on POSIX threads because
1957 the number of global structures is limited. NMEM no longer re-uses blocks
1958 between threads ; it simply free's memory immediately but allocates in
1959 "large" chunks as usual. We don't expect any performance penalties
1960 because of this. The yaz_log system is still using a global log_level so
1961 caution must be taken when modifying it with yaz_log_init_.. +
1962 yaz_log_mask_str. This, however, should not cause any trouble because
1963 these functions are called during initialization of application code
1964 anyway. `yaz-config --libs server` returns libs for server applications;
1965 `yaz-config --libs` returns libs for non-server applications.
1967 New OID database - with public definitions in oid_db.h. Removed old OID
1968 database including the head oid.h and definitions such as enum oid_value
1969 and struct oident. The new OID database uses the same string names as
1970 before but the 'protocol' is gone. There are now only two representations
1971 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1972 converts from string to OID; functions with prefix yaz_oid_to_string
1973 converts the other way.
1975 Change to emit_term() in CQL-to-PQF query translation: when a term has
1976 the /regexp relation modifier, do not process it for leading and
1977 trailing "^" and "*", which have quite different meanings in regular
1980 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1981 write handlers no longer carries a 'last' parameter. This will make
1982 yaz_iconv flush "less" characters. A flush is performed by call to
1983 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1985 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1986 removed, because function yaz_query_to_wrbuf does the same.
1988 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1989 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1991 Deprecated MARC utility functions removed.
1993 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1996 Branch split: YAZ_2_1_55_branch
1998 --- 2.1.54 2007/03/16
2000 Fix to ZOOM-C so that transparent reconnection is properly handled on
2001 connections that are in asynchronous mode.
2003 Fixed compilation on OpenBSD 4.0.
2005 Large strings in GRS-1 records are now properly displayed in yaz-client.
2007 Added character conversion support for "advancegreek"; based on patch from
2010 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2011 sequence is met. Before the error was not set so it would be unknown.
2013 Adjust yaz-marcdump MARC reader so that it skips until record separator
2016 --- 2.1.52 2007/03/07
2018 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2019 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2020 fd_set structure used as a bitmask for the FDs to be selected on.
2022 Using ACX_PTHREAD macro to check for POSIX threads.
2024 Fixed have-vsnprintf check.
2026 --- 2.1.50 2007/02/23
2028 Fixes for configure on BSD. Bug #900.
2030 Added snprintf/vsnprintf wrappers for systems that don't have
2031 limits (heavens forbid).
2033 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2034 created before all previous tasks were completed and removed from the
2035 task queue, the new task could be removed by a mistake.
2037 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2039 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2041 Fixed bug #832: Problem with MARC/charset in yaz-client.
2043 Fixed bug #668: save command line history for yaz-client.
2045 Fixed bug #830: pkg-config support.
2047 --- 2.1.48 2007/01/23
2049 Extended ZOOM result set options with two options that may be read by
2050 a client: resultSetStatus and presentStatus with values as specified for
2052 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2054 Fixed bug #827: Using SSL fails on Debian etch.
2056 Fixed bug #826: Weird looking chars for set of MARC records.
2058 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2059 that is treated as an ItemOrder with itemRequest being an XML document
2060 external. The value of "doc" is the content.
2062 Extended the GFS search facility. New member of bend_search_rr
2063 'estimated_hit_count' signals that hits is known to be an estmate
2064 (higher or lower than real hit count). New member 'partial_resultset'
2065 signals that the search was partial (hit count is lower or equal than
2066 real hit count). For Z39.50, the information is stored in resultSetStatus
2067 member of SearchResponse APDU. For SRU, the information is signalled
2068 via SRU diagnostic 59: "Result set created with valid partial results
2071 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2073 --- 2.1.46 2007/01/13
2075 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2077 Added ZOOM_connection_peek_event.
2079 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2080 the following new functions:
2081 ZOOM_event_nonblock, ZOOM_connection_process,
2082 ZOOM_connection_get_{socket,mask,timeout},
2083 ZOOM_connection_fire_event_{timeout,socket}.
2084 The existing blocking event handler, ZOOM_event, is a wrapper for the
2085 + blocking ZOOM_event_sys_{poll,select}.
2087 Implemented function ccl_xml_config which parses XML version of CCL
2088 configuration (bug #798).
2090 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2092 Added timings utility (yaz/timing.h)
2094 --- 2.1.44 2007/01/03
2096 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2099 Fixed bug #779: Rotation of apdu.log fails.
2101 Fixed for character set conversions:
2102 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2103 Honor G1 set in MARC-8 decoding.
2105 --- 2.1.42 2006/12/17
2107 Fixed bug #775: char conversion does not handle Alternative UTF-8
2110 Implemented function yaz_marc_read_line which parses MARC line format
2111 records. There is a wealth of formats out there. So far, this function
2112 reads line records produced by yaz_marc_write_line.
2114 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2115 more generic and easier to remember(!) options: -i format and -o format
2116 which specifies input format and output format respectively - where
2117 format is one of "marc", "marcxml", "line", "marcxchange".
2119 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2120 does not print anything except warnings for records.
2122 For yaz-marcdump, added support for MARC split into files (-s) with a given
2125 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2126 spec, at http://www.loc.gov/standards/sru/record-update/
2127 This has changed the binary layout of the following structs:
2128 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2129 bend_update_rr . Patch by Ko van der Sloot.
2131 Added GFS utility function bend_assoc_is_alive which returns 1 if
2132 association is still alive (client is connected); 0 otherwise (client
2133 closed connection). This allows busy servers to stop working for
2136 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2137 been a separate piece of software. This version of ziffy has been modified
2138 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2140 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2142 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2143 Client code may now interrogate options such as "init_opt_sort" to
2144 find out whether the server claims to support various options.
2146 --- 2.1.40 2006/11/27
2148 Added utilities yaz_{set,get}_esn to set/get element set name from
2151 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2152 of YAZ and has been so since YAZ 2.1.10.
2154 Implemented ZOOM_record_error which returns error information for
2155 record (surrogate diagnostic).
2157 --- 2.1.38 2006/10/31
2159 Updates for SRU Update by Ko van der Sloot:
2160 1. Changed name from "operation" to "action"
2161 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2162 versions in the code, marked as 'backward compatible'.
2163 3. Added diagnostics for SRU Update.
2165 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2167 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2169 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2171 For GFS, fixed problem with SRU diagnostic 'First record position out of
2172 range' being issued for 0 hits.
2174 zoomtst10 part of Windows Build.
2176 --- 2.1.36 2006/10/13
2178 Implemented yaz_filepath_comp which splits a path into file path
2179 components (required by Zebra 2.0.3+).
2181 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2182 BSD inspired license until now so this should not have any real impact on
2183 anybody. See http://www.opensource.org/licenses/bsd-license.php
2185 Fixed bug #687: Missing log lines.
2187 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2190 Fixed bug #689: SRU diagnostics to be added.
2192 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2193 whether a connection is idle (no more work do do).
2195 --- 2.1.34 2006/10/04
2197 Change type of optval from long to int for invocation of setsockopt with
2198 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2200 Added support for specifying the max log file size for the Generic
2201 Frontend Server. The size is given with option -r.
2203 --- 2.1.32 2006/09/21
2205 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2207 --- 2.1.30 2006/09/17
2209 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2212 Fixed bug in Generic Frontend Server that could cause a server to stop
2213 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2215 For the generic frontend server, the maximum record size is used as maximum
2216 size of incoming packages (SRU + Z39.50). The value until was previously
2217 only used in Z39.50 Init negotiation and, later, in a session controlled
2218 sizes of records returned. This is controlled using -k option. It can be
2219 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2221 --- 2.1.28 2006/09/04
2223 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2226 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2228 New option for yaz-marcdump -lpos=value which allows setting a portion
2229 of MARC header to a certain value.
2231 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2233 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2234 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2236 --- 2.1.26 2006/08/15
2238 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2241 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2243 --- 2.1.24 2006/08/08
2245 Fixed MARC ISO2709 encoding routines to deal with character set
2248 Minor changes to GFS logging. Database included in search request log
2251 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2252 cached/multiple records.
2254 Shared libraries are built by default on Unix+configure.
2256 Changed cql2pqf transformation to use a different evaluation order. The
2257 new order is: always, relation, structure, position, truncation, index
2258 and relationModifier. Old order was: always, relation, relationModifier,
2259 structure, index, position, truncation. Note that the the latter ones
2260 override former ones for identical attributes.. The new scheme means that
2261 it is possible to override any existing attribute with a relationModifier.
2262 And also that it is possible to override everything for the index rule
2263 (except the ones listed in relationModifier). No order is perfect but this
2264 one, we believe, covers more real cases.. The "always" should have been
2265 called "default", since the attributes there can be overridden with all
2268 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2269 compilation phase, but also for yaz-config --cflags output. This allows
2270 us to have public headers with Libxml2 stuff in them . It should also,
2271 eventually, make Libxml2 checks redundant in packages using YAZ, such
2274 --- 2.1.22 2006/06/15
2276 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2277 stored in uri, message and details.. Previously diagnostics were stored
2278 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2279 compatibility.. but he's probably the only one affected, so.
2281 Added support for CCL, compiled on the client side, in ZOOM-C. This
2282 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2283 input; the resulting query objects can be used for for searching with
2284 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2286 YAZ' configure searches for OpenSSL by default.
2288 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2289 SL_CTX_use_certificate_file. See
2290 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2291 for more info. Thanks to Ko van der Sloot.
2293 --- 2.1.20 2006/06/02
2295 Bug #600: SRU GET, POST support for yaz-client. Introduced
2296 command 'sru' which selects method SOAP/GET/POST.
2298 Allow missingValueAction to be specified for the sortspec string -
2299 function yaz_sort_spec. By default, the missing value action is null.
2300 Use ! to specify "abort". Use = followed by stringvalue to specify default
2303 Ensured that Present-handler (if defined) is called in GFS before any call to
2304 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2305 searchRetrieve requests.
2307 Documentation for YAZ is now based on the Docbook XML/XSLT using
2308 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2309 is no longer depending on jade/openjade or docbook-to-man scripts.
2310 PDF is no longer part of the distribution - but can optionally be
2311 made using DSSSL/jadetex or FOP.
2313 Added retrieval handling support in Generic Frontend Server to support
2314 conversion between MARC/XML as well as XSLTtransforms. See
2315 etc/yazgfs.xml for an example.
2317 Added Authentication support to Generic Frontend Server in SRU
2318 mode. Authentication using HTTP Basic is supported, as is the use
2319 of 'x-username' and 'x-password' parameters in the request itself.
2321 Added support for a new character set MARC8s identical to MARC8 except
2322 that it converts combined characters to single Unicode characters in the
2323 Latin-1 range (when possible).
2325 --- 2.1.18 2006/04/24
2327 ASN.1 compiler 0.4: generates brief Doxygen file header for
2328 generated .h/.c files.
2330 Utility yaz_iconv now supports conversion to MARC-8.
2332 New facilities for the MARC module. The reading - and writing of
2333 content are separate methods for the yaz_marc_t handle. The following
2334 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2335 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2336 format). Write functions have prefix yaz_marc_write_.. The existing
2337 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2338 available. Removed support for OAI-MARC and simplexml (not the
2339 simplexml from PHP5).
2341 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2342 to be returned for this connection.
2344 --- 2.1.16 2006/03/31
2346 Allow multiple languages and charsets to be specified with
2347 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2348 negcharset iso-8859-1,utf-8
2350 Translation of proximity nodes from CQL into PQF now works.
2352 Moved to automake 1.8, 1.9.
2354 Added function yaz_log_set_handler which allows a log handler to be
2355 installed. This handler will be called for all log messages. Output
2356 to file is also produced; but that can be disabled by passing NULL
2357 fname to yaz_log_init_file.
2359 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2361 For SRW (including GFS), accept application/soap+xml as content-type
2364 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2365 produces NO stylesheet reference even if a default stylesheet is specified
2368 --- 2.1.14 2006/03/14
2370 Updated Windows package to include yazd.dll + yazd.lib for the
2371 Development component.
2373 If the environment variable YAZ_LOG is set, then it is used as a
2374 string indicating the default level of logging to use if not
2375 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2376 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2377 used as before. So, for example, to omit warnings from YAZ logging,
2378 export YAZ_LOG=-warn
2380 cql_transform() now map structure and other attributes before indexes,
2381 so that index-specific structures and other attributes can override
2382 defaults. So now a combination of mapping specifications such as:
2384 index.dc.date = 1=date-modified 4=5
2385 does the right thing.
2387 cql_transform() now also respects the "always" mapping specification,
2388 which establishes an initial set of attributes to be used for all
2389 terms except where overridden by more specific attributes associated
2390 with the index, relation or modifier.
2392 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2393 which mode to use; one of "post", "get" or "soap" (SRW, default).
2395 Fixes for yaz_iconv routines: changed trie-based character set conversions
2396 to use only non-negative values for bit fields due to Sun's C compiler not
2397 supporting negative values.
2399 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2400 sequences where not read correctly. Fix by Rustam Usmanov.
2402 Updated win/makefile to use options, settings which makes things
2403 compile with VS C 2005.
2405 --- 2.1.12 2006/02/01
2407 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2409 In ZOOM socket code, use select instead of poll on MacOSX.
2411 ZOOM-C now support client-side compilation of CQL into RPN that is
2412 sent to the server, enabling CQL to be used against all Z39.50
2413 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2414 ZOOM_query object, and submit it using ZOOM_connection_search().
2415 The CQL-to-RPN translation uses a configuration file, the name of
2416 which must be specified in the Connection's "cqlfile" option.
2418 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2419 function, which takes as its start-term parameter a ZOOM_query object
2420 (which may have had either CQL or RPN set into it).
2423 --- 2.1.10 2005/11/29
2425 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2426 GFS to support this as well. Backend handler, bend_srw_update, does the
2427 update work. Code contributed by Ko van der Sloot.
2429 Allow retrieval of Search Result-1 information in ZOOM by the use of
2430 options that are attached to a result set. ZOOM documentation updated
2433 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2434 UTF-8 conversion. Patch by Raj Patel.
2436 Added option -m to GFS to control formatting of timestamps in log file.
2438 Added 'exit' as synonym for 'quit' in yaz-client
2440 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2441 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2442 for the new members. Patch by Ko van der Sloot.
2444 Added support for SRU POST. It is supported for content-type
2445 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2447 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2448 Instead make the library libyaz.la multi-threaded. Threading as a whole
2449 can still be disabled by configure option --disable-threads. Previosly,
2450 with older GLIBCs there were problems with MT libs under Apache. This
2451 has now been fixed a long time ago.
2453 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2456 CQL module modified to be case insensitive for relations/indexes/operations.
2458 Fixed bug in CQL transform code: incorrect value relationModifieder
2461 Added 'show all' command for yaz-client which retrieves all results
2464 Added new yaz-client, xmles, which takes a (private) OID and
2465 a document to be sent as an extended service request.
2467 Describe new yaz-client commands wait_response and set_auto_wait.
2469 Increase TCP/IP listener backlog from 3 (which I am guessing was
2470 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2471 that the socket will queue as many incoming connections as it's able
2472 to handle ongoing connections. In other words, it will never now
2473 refuse a connection that it would be able to handle merely because
2474 it's not got around to accepting() enough of the pending connections
2475 yet. This is the behaviour anyway under Linux, where the listen()
2476 argument is ignored; but not under BSD and on systems such as
2477 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2478 YAZ-based servers should now be uniform across operating systems in
2481 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2482 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2483 This allows yaz-marcdump to read large MARC batches (>2 GB).
2485 Modified all YAZ source files - except the source which is auto-generated
2486 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2489 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2490 corresponding to the existing *_setl() function. These allow option
2491 values containing arbitrary valuues.
2493 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2494 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2495 except that it returns an indicator of whether or not the sort
2496 criterion was accepted (0 for OK, -1 for invalid).
2498 --- 2.1.8 2005/06/07
2500 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2501 MARC output rather than returning "new" buffer.
2503 yaz-client warns about unknown init options.
2505 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2507 --- 2.1.6 2005/05/24
2509 Added support for SRW sort in Generic Frontend Server. Patch
2510 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2511 sortKeys - or NULL if none is provided.
2513 Fixed bug #307: It was impossible to specify indefinite/no timeout
2514 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2517 Added support for multiple languages and charsets to be specified in
2518 ZOOM. Each charset/language is separated by a blank. If negotiation is
2519 in effect in init-response, Option
2520 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2521 Code based on patch by Vasiliy Osadchuk.
2523 Fixed bug #306: infinite recursion that occurred when calling
2524 yaz_log_level_init as the first call (before other log level or
2527 Fixed bug in scan handling in front end server: if preferred-Position-In-
2528 Response was non-present, a NULL pointer referece was performed.
2530 --- 2.1.4 2005/04/26
2532 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2533 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2534 now defined for all those error codes. So instead of putting 109 in
2535 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2536 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2538 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2541 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2543 Program yaz-client now exits and produces an error message if multiple
2544 Z39.50 servers are specified on the command line (none or one allowed
2547 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2550 --- 2.1.2 2005/03/16
2552 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2554 Fixed bug #272: Preserve spacing for CCL terms.
2556 --- 2.1.0 2005/03/14
2558 Added support for virtual hosts and multiple backend servers for
2559 the YAZ frontend server. The configution is XML based and
2560 support specificition of CQL to RPN mappings and explain information.
2561 See section "Virtual Hosts" in the YAZ manual.
2563 Extended OPAC display utility. OPAC display utility renders
2564 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2565 to supplement yaz_marc_decode_wrbuf.
2567 Fixed a bug in MARC decoder that could caused it to crash for some
2568 invalid MARC records. More diagnostics and warnings where added in
2569 XML output (warnings, etc are stored in comments).
2571 --- 2.0.34 2005/02/08
2573 Fixes for UNIX domain sockets. Bug #261.
2575 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2577 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2578 Added yaz_marc_subfield_str which defines subfield lead string which is
2579 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2580 yaz_marc_endline_str which defines end of fields string used in
2581 YAZ_MARC_LINE format. Default string is newline.
2583 Experimental support for MarcXChange. This format can be produced
2584 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2585 http://www.bs.dk/standards/MarcXchange.xsd
2587 Added yaz-client commands scansize that sets maximum number of
2588 entries to be returned by scan.
2590 --- 2.0.32 2005/01/11
2592 Added support for SRW scan in yaz-client and Generic Frontend Server.
2594 * Added whereInList member to SRW Scan Term.
2596 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2598 Fixed NMEM system to return aligned blocks on the smallest boundaries
2599 that are suitably aligned for all possible types on the particular
2600 architecture YAZ is being built for.
2602 --- 2.0.30 2005/01/04
2604 Fixed numerious warnings that was issued with newer versions of GCC.
2606 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2607 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2610 Make YAZ Generic Frontend Server slightly faster.
2612 Enhance (and reduce) logging for Generic Frontend Server.
2614 Revert YAZ log system so that it flushes every write operation
2615 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2617 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2618 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2619 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2620 will effectively disable old definitions.
2622 --- 2.0.28 2004/11/09
2624 Added yaz_log_time_format which specifies log format using
2627 Added yaz_log_module_level which returns mask for a module. Value
2628 is non-zero mask a if module is enabled; zero if disabled.
2630 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2631 in include/yaz/cql.h.
2633 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2635 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2637 Fixed bug #172: RPM builds does not enable SSL.
2639 Doxyfile.in part of dist. Doxyfile generated by configure.
2641 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2642 are given and the corresponding component does not exist.
2644 Extend CCL documentation in YAZ reference. Describe r=r.
2646 --- 2.0.26 2004/10/01
2648 Fixed MARC->MARCXML conversion to properly deal with
2649 fields, subfields, indicators having non-ASCII characters.
2651 Fixed MARC->MARCXML conversion so that ASCII control characters
2652 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2655 Added YAZ GFS support for conversion from Z39.50 surrogate
2656 diagnostics to SRW surrogate diagnostics.
2658 Bug fix: YAZ GFS did not return schema in explainResponse.
2660 --- 2.0.25 2004/09/30
2662 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2663 now converts recordSchema to elementSetName as well as schema URI.
2665 Fixed bug in COMSTACK that prevented HTTP request packages from being
2668 --- 2.0.24 2004/09/29
2670 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2671 does not require white-space before and after the dash in a range, e.g.
2672 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2675 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2676 due to new GCC removing "redundant" code.
2678 Added yaz-client commands scanpos and scanstep that sets preferred
2679 position and step-size for scan.
2681 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2683 Added CCL utility ccl_qual_buf which parses one or more CCL
2684 spec lines in a buffer.
2686 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2687 of name and value - ignoring empty lines and comments.
2689 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2691 Added odr_get_element_path which returns current element path for an
2692 ODR handle. This utility is useful in error handling or user-defined
2695 Added ODR_PRINT utility odr_set_stream which is is a more generic
2696 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2697 to a write function and pointer to close function. The close function - if
2698 non-NULL - will be called during odr_destroy.
2700 Fixed bug in CCL parser where truncation char was not removed from
2701 right side when truncation=both was in effect.
2703 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2706 --- 2.0.23 2004/08/11
2708 Fix buffer overrun in CQL parser when dealing with proximity (%).
2710 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2711 to UTF-8/UCS conversion is now only based on codetables.xml.
2713 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2715 --- 2.0.22 2004/08/06
2717 Add support for more "commit changes" in ZOOM (uses Extended Services).
2719 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2722 Yet another small fix for configure of SSL.
2724 --- 2.0.21 2004/05/14
2726 Fix SSL libs for configure when --with-openssl=DIR is given.
2728 --- 2.0.20 2004/05/10
2730 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2732 SSL comstack now uses yaz.pem certificate file on server side
2733 by default. Certificate filename can be configured by calling
2734 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2736 Fix bug regarding multiple calls to ZOOM_connection_connect.
2738 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2740 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2741 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2743 ZOOM now allows inspection of X509 peer certificate for verification.
2744 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2746 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2747 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2748 as "modular" but it simplifies things.
2750 Added cs_get_peer_certificate to that returns peer X509 PEM.
2752 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2753 NULL if SSL is unavailable.
2755 Documentation about MARC decoding tools.
2757 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2759 --- 2.0.19 2004/03/30
2761 Rename CHANGELOG to NEWS to follow GNU style packing.
2763 Fix bug with missing initialization of member in init_diagnostics.
2764 This bug affects threaded version of GFS server.
2766 --- 2.0.18 2004/03/20
2768 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2771 Ensure zlib.dll is packed with Windows install.
2773 --- 2.0.17 2004/03/17
2775 Fix encoding of xsd:string to use text instead of CDATA.
2777 Fix endless loop in CQL parser with unbalanced ".
2779 Use a more compact way to store MARC-8 conversion tables.
2781 --- 2.0.16 2004/03/16 Debian only
2783 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2786 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2791 --- 2.0.15 2004/03/01
2793 Another fix for decoding of XML packed records.
2795 --- 2.0.14 2004/02/25
2797 Fixes for Chunked encoding. White space not ignored after length spec.
2799 Update NS and use default NS for SRW diagnostic elements.
2801 --- 2.0.13 2004/02/23
2803 Implement ZOOM_resultset_cache_reset which resets record cache.
2805 Implement ZOOM_resultset_sort which sorts a result set.
2807 Implement chunked HTTP transfer.
2809 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2811 --- 2.0.12 2004/02/16
2813 Added member 'schema' to bend_explain_rr structure so that backend
2814 can specify explain record identifier. Defaults to Zeerex 2.0.
2816 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2818 --- 2.0.11 2004/02/16
2820 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2823 Added init command for yaz-client which sends "extra" init request.
2825 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2826 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2828 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2830 Make ZOOM error code for "invalid query".
2832 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2834 --- 2.0.10 2004/02/05
2836 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2839 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2841 Added option -p <file> to make Generic Frontend Server to write PID file.
2843 Added option -D to put Generic Frontend Server in background on its own.
2845 Make ZOOM C recognize option "password". If unset, "pass" is used
2846 (for backwards compatibility).
2848 Fixed a bug in Generic Frontend Server that could make it crash if a
2849 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2852 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2853 Must be issued before open, in order to be in effect.
2855 --- 2.0.9-6 2004/01/12 Debian/Windows
2857 Make the SRU server more picky WRT unknown params, etc.
2859 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2861 New YAZ client command, options, that sets Z39.50 options.
2863 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2864 options from a string of tokens (one token for each option bit).
2866 Update SRW diagnostic code messages.
2868 --- 2.0.9-5 2004/01/07 Debian/Windows
2870 Handle user defined stylesheet for SRW/SRU.
2872 --- 2.0.9-4 2004/01/06 Debian/Windows
2874 Fix bug in decoding of Content-Length.
2876 --- 2.0.9-3 2004/01/06 Debian/Windows
2878 Fix a bug with decoding of XML packed records.
2880 --- 2.0.9-2 2004/01/05 Debian only
2882 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2884 Fix bug in SRW/SRU diagnostics decoding.
2886 --- 2.0.9 2004/01/05
2888 Fixed bug in Generic Frontend Server which could drop records exceeding
2889 preferred message size. Reported and fixed by Irina Dijour.
2891 Fixed calculation of package size for structured records in Generic
2892 Frontend Server. Reported and fixed by Irina Dijour.
2894 Fixed namespace for SRW/SRU diagnostics.
2896 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2898 --- 2.0.8 2003/12/22
2900 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2901 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2904 CQL changes to reflect recent changes to the specification:
2905 * Documentation talks about context sets instead of index sets.
2906 * Documentation talks about indexes instead of qualifiers.
2907 * The CQL-to-PQF transformer's configuration file now uses
2908 "index.set.name = <attributes>" instead of the old form
2909 "qualifier.set.name = <attributes>". (Both forms are still
2910 understood but the latter is deprecated.)
2911 * CQL terms with no explicit index specified are now interpreted as
2912 cql.serverChoice instead of srw.serverChoice (which of course
2913 behaves exactly the same.)
2915 --- 2.0.7 2003/12/16
2917 MARC conversion can now generate ISO2709 output in another
2918 character set. yaz-marcdump uses this facility if you invoke it
2921 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2922 functions from there can be used from C++.
2924 --- 2.0.6 2003/12/04
2926 Frontend server now transfers memory from decoded packages to stream
2929 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2930 references to show up.
2932 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2933 the ZOOM Abstract API. The older names for the same options are still
2934 also supported for the benefit of old applications.
2936 ZOOM-C supports "implementationId" and "implementationVersion" options
2937 to go along with "implementationName". These allow the user code to
2938 specify identification strings to be sent to servers.
2939 Add OID for the new ExtLite attribute set.
2941 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2942 as requested/supplid by Ere Maijala <ere@atp.fi>
2944 For generic frontend server, reverse the order of
2945 "toolkit-supplied / application-supplied" strings sent as implementationId,
2946 Name and Version. Also, remove the spaces around the slash. This brings
2947 the GFS in line with the behaviour of ZOOM-C on the client side.
2949 Add function ZOOM_scanset_display_term.
2951 yaz-client shows scan displayTerm if present.
2953 Utility yaz-iconv is now installed by default along with the man page
2956 Extend configure check for OpenSSL to use pkg-config where available (such
2959 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2960 server to specify uid/gid/mask for socket using the format
2961 unix:[user=uid,][group=gid,][umask=mask,]file=path
2962 If file= is omitted the existing format is assumed, e.g.
2964 in which case the mask is 0666 (rw for everybody).
2966 Major restructure of YAZ source. All source in libyaz is in src directory.
2967 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2968 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2970 Added man page for utility yaz-marcdump (used to be called marcdump).
2971 yaz-marcdump is installed by 'make install'.
2973 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2974 of incoming package failed.
2976 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2978 Change prototype of odr_perror: add const to message string.
2980 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2982 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2983 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2984 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2985 DNS lookup. There should not be any compatibility problems with this
2986 assuming that blocking=1 or 0 is used.
2988 Fix bad reference in UNIX comstack in function cs_addrstr.
2990 Fix for compilation on AIX.
2992 The generic front-end server (server/seshigh.c) now supports returning
2993 Init diagnostics to the client in User-information-field, in
2994 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2997 --- 2.0.4 2003/09/04
2999 Allow any CQL relation (not just all,any,exact,scr).
3001 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3002 that features the same UI.
3004 Implemented command update0 in YAZ client which is equivalent to
3005 update but uses old of Ext Update ASN.1.
3007 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3008 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3009 Previously no OID was used for this info.
3011 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3012 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3013 returns 'malformed search term' otherwise.
3015 SortResponse member resultCount now set to NULL in sort handler of
3018 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3021 Add three new utility functions for translating OIDs between various
3022 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3023 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3024 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3025 char *oid_to_dotstring(const int *oid, char *oidbuf);
3026 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3028 Reverted modifications for ES Update definition for z_IU0Update
3029 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3030 is back to YAZ 2.0.2.
3032 String value attributes for CCL parser.
3034 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3035 which their FirstSearch server returns in Init responses, sometimes
3036 carrying useful diagnostic information when Init fails. This has the
3037 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3038 "z39.50/oclcui.asn", where its definition is somewhat different from
3039 what OCLC document on their web-site, as required to interoperate with
3042 Support for anonymous authentication in yaz-client. Use the command
3045 * Fix the OID of the Index Data-local "admin" Extended Service from
3046 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3047 the 1000, which indicates a locally-defined OID, was a mistake.
3049 --- 2.0.3 2003/06/20
3051 Fix CCL directive @case handling so that it affects string match for
3052 both CCL keywords and qualifiers.
3054 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3055 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3056 Decoder has been updated with ASN.1 changes as listed in
3057 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3058 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3059 z_IUUpdate, remains unchanged.
3061 ZOOM_record_get may now return a record in a specific character set.
3062 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3063 "from" is the character set of record as returned by target. "to" is
3064 the character set to be returned. If omitted, "to" is UTF-8.
3066 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3068 New ODR utility, odr_getelement, which returns name of element for
3069 which encoding/decoding failed.
3071 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3072 in cases where a required element was omitted.
3074 Bug fix: some MARC8 sequences were not converted.
3076 New ZOOM option "step" which specifies number of records to be
3077 retrieved in one chunk. Used in conjunction with "start" and "count".
3079 SRW support for yaz-client. Use scheme http: to use it, e.g.
3082 yaz-client no longer does (un)intelligent character set conversions
3083 by default. Can be enabled with charset and marc_charset commands.
3085 xmalloc trace fix for 64-bit systems such as DEC alpha.
3087 Solaris 2.6 compile fix.
3089 New function, cql_strerror() translates SRW error codes, as returned
3090 by cql_transform_error(), into human-readable English strings. Used
3091 in yaz-client diagnostics when appropriate.
3093 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3094 converts it into a type-1 query which is sent to the server. This
3095 makes CQL available for use with all Z-servers, as opposed to the tiny
3096 minority that can handle CQL queries themselves.
3098 --- 2.0.2 2003/04/28
3100 New Debian package layout similar to the Redhat Package layout.
3102 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3103 and search result respectively.
3105 --- 2.0.1 2003/04/25
3107 Redhat package is now several packages: libyaz (runtime libraries),
3108 libyaz-devel (development and documentation, and yaz (utility programs).
3109 Package spec file by Morten Bogeskov.
3111 New member 'schema' in struct bend_fetch_rr which the name of requested
3112 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3113 handler MAY set this to reflect the schema of the returned record.
3115 New member 'display_term' in struct scan_entry. GFS now sets member entries
3116 and allocates scan entries to be filled by user scan handler. In previous
3117 version, entries member was allocated by the scan handler. That still works,
3118 but the GFS will ignore member display_term - assuming it was NOT set by
3119 the handler. The fact that the GFS now allocates the entries both allows
3120 for new members and makes a scan handler easier to write.
3122 Fix CQL lex buffer overflow.
3124 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3125 SRU default recordPacking is string.
3127 SRU protocol support for frontend server.
3129 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3131 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3133 Added scan for the ZOOM shell (zoomsh).
3137 * String Identifers for Schemas (Amendment 5).
3138 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3139 Old definition for schema
3140 Odr_oid *schema; /* OPT */
3145 Z_InternationalString *uri;
3146 #define Z_Schema_oid 1
3147 #define Z_Schema_uri 2
3150 * resultCount parameter to Sort Response (Amendment 1).
3151 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3153 Support for SRW 1.0 over HTTP. This is an optional feature and
3154 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3157 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3158 on the same port. SRW SearchRetrieveRequests are mapped
3159 to bend_init,bend_search,bend_fetch,bend_close.
3161 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3163 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3164 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3166 ZOOM connections are SRW based if schem http is used for hostname
3167 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3168 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3170 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3171 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3172 distance=n, order=true/false, relation=le, prox unit=word. If
3173 n is omitted, distance 1 is used.
3175 Fixed problem with C compiler include path in wrong order.
3177 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3178 on Solaris. Patch from Ko van der Sloot.
3180 New MARC decode API. All new functions operate on a yaz_marc_t
3181 handle. The most important new functions are: yaz_marc_create,
3182 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3183 decode and destroy respectively. Decoder can produce formats
3184 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3185 include/yaz/marcdisp.h.
3187 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3188 to UTF-8, UCS-32, wchar_t or Latin-1.
3190 * Prototypes for yaz_iconv_-functions moved to separate header
3191 include/yaz/yaz-iconv.h.
3193 Make a few private functions 'static' in unix.c. This prevents
3194 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3196 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3197 are set when Init Response is received.
3199 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3200 but returns diagnostic set as well.
3202 New function yaz_strerror which is a portable wrapper for
3203 strerror/strerror_r/GetLastMessage.
3205 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3206 is returned for MARC. If type is "oai", then OAI MARC is returned.
3208 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3211 --- 1.9.2 2002/11/26
3213 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3215 Fix bad race conditions on SIGTERM and terminate gracefully in
3218 Move retrieval (data1) module to Zebra since nobody seems to be
3221 Add GRS-1 render for ZOOM using same format as yaz-client.
3223 --- 1.9.1 2002/10/05
3225 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3227 Fix broken ESpec handling in data1 module.
3229 SGML reader parses comments and makes them part of the data1 tree.
3231 Added several type casts so that YAZ compiles as C++ code.
3233 ZOOM didn't handle PDU encoding failures properly.
3235 Added more Bib-1 diagnostics (approved extensions).
3237 GNU configure: better check for iconv.
3239 More portable use of accept, getpeername. Check for socklen_t. Use
3240 int/size_t if socklen_t is not defined.
3244 PQF parser rejects bad queries - including those with extra
3245 characters in them. PQF parser used to silently ignore that.
3246 Cleaner API for PQF added, which allows you to get detailed
3247 error information for bad queries (see yaz/pquery.h).
3249 Fixed bug in ZOOM_record_get for type "database".
3251 Implemented mini iconv library supporting conversions between
3252 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3254 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3256 --- 1.8.9 2002/08/20
3258 Fixed ZOOM C record cache so that preferredRecordSyntax and
3259 elementSetName is used to check for already fetched records.
3261 --- 1.8.8 2002/08/02
3263 Added three members in bend_initrequest structure to facilitate
3264 character set negotiation.
3266 Fixed a bug in frontend server that could cause indefinite
3267 loops under rare conditions.
3269 Revised character set utilities (charneg.h) so that encoding
3270 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3272 For PQF, directive @term <type> sets term type for Scan/Search.
3273 Here <type> is general, string, numeric, null. The term type
3274 is inherited - just like @attr.
3276 New call odr_set_charset that sets character set conversion for
3277 international-strings on a ODR stream. Prototype is:
3278 int odr_set_charset(ODR o, const char *to, const char *from);
3279 The InternationalString is still represented as C string in YAZ
3280 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3281 won't). On the protocol level, you can use any encoding.
3283 Support for UNIX sockets in ZOOM.
3285 Solaris recv sometimes returns errno == ENOENT. It is treated as
3286 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3288 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3289 both client and server. Code by Morten Bogeskov.
3291 --- 1.8.7 2002/05/22
3293 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3294 that they can be used directly from Visual Basic. You must recompile
3295 your windows APP if you're using ZOOM.
3297 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3298 Commands "lang" and "charset" sets language and character set respectively.
3299 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3300 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3302 Attributes from multiple CCL fields may be OR'ed rather than merged
3303 using directive "@field or". Fields are still merged by default -
3304 equivalent to "@field merge".
3306 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3309 Fixed bug in zget for parameter ExtendedServicesResponse.
3313 --- 1.8.6 2002/03/25
3315 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3317 Client displays USR.1:SearchResult-1 (hits per term).
3319 Additional Search Info for search in Generic Frontend Server.
3321 Fixed CCL parsing of "field=s".
3323 WIN32 installer - using the excellent NSIS software from nullsoft.
3325 Fixed CCL parsing of "field = - <number>".
3327 Added function yaz_marc_decode that decodes MARC for line mode
3328 display or XML (similar to that used by JZKit).
3330 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3331 Z39.50. But ISO/ILL was, however.
3333 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3334 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3336 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3337 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3339 --- 1.8.5 2002/02/03
3341 New YAZ client features: Command completion and new commands:
3342 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3343 Code provided by Jacob Poulsen.
3345 New call oid_trav, that visits all registered OIDs via callback.
3347 Function ZOOM_record_get now returns const char pointer rather than
3348 void pointer. It saves a lot of type casts.
3350 For YAZ client, command "auth" now allows you to set authentication
3351 in IdPass style. It is enabled when three tokens are given - order
3352 is user, group and password.
3354 Fix memory leaks in MARC record handling for ZOOM.
3356 New option for YAZ client, -k <kilobytes> that sets
3357 maximum record size. Similar to -k option for generic frontend
3358 server and yaz-ztest.
3360 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3362 Prefix query parser reports "fail" when bad attribute set is given.
3364 Fix in MARC decoder. Proximity logging. Fix for attribute set
3365 in scan handler for server. Patches by Shigeru Ishida.
3367 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3370 Configure option --with-openssl=<dir> now works when a directory is
3371 specified. Patch provided by Morten Bogeskov.
3373 New option for YAZ client, -u <auth>, that sets authentication.
3375 ZOOM fix: error information was sometimes "missing", since error
3376 was cleared/reset too when it shouldn't.
3378 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3380 --- 1.8.4 2002/01/04
3382 Scan for ZOOM API. New object ZOOM_scanset. New functions
3383 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3384 ZOOM_scanset_destroy.
3386 New ZOOM function, ZOOM_connection_last_event, that returns type
3387 of last event (such as "receive data", "send data", "apdu received",
3390 New ZOOM option, schema, that specifies schema for retrieval.
3392 New CCL feature. Qualifiers can be aliases for one or more
3393 other qualifiers (if more than one is given, OR is used).
3395 ZOOM uses named result sets if target supports it.
3397 Two new YAZ client commands: . (dot, which sources a script of YAZ
3398 client commands), and ! (to execute shell command.). Implemented
3401 Working on Debian packages.
3403 --- 1.8.3 2001/11/19
3405 YAZ client enables named result sets only if target supports it.
3407 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3409 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3410 with key="host" to get same result.
3412 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3413 Function Z3950_resultset_record(s) returns references to records
3414 "owned" by resultset. To become owner use Z3950_record_clone.
3416 Function z_ext_record handles Extended Services. Thanks to
3419 --- 1.8.2 2001/11/12
3421 CCL Parser fix: ignore token comma when dealing with and-lists.
3423 Documentation updates for COMSTACK.
3425 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3426 Changed prototype Z3950_records. For some functions, int parameters
3427 were changed to size_t.
3429 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3432 New MARC decode/display function, marc_display_exl, which properly rejects
3433 non-ISO2709 records. YAZ client uses it.
3435 --- 1.8.1 2001/10/29
3437 Fix bug: local attribute set wasn't set correctly in PQF strings.
3441 * Old Z39.50 codecs no longer supported.
3443 Added ZOOM C binding. See http://zoom.z3950.org/
3445 Renamed states for COMSTACKs to avoid confusion with events.
3447 Implemented cs_look and proper cs_rcvconnect.
3449 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3451 Configure detects POSIX threads on OpenBSD.
3453 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3454 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3456 When error is returned from present handler, non-surrogate diagnostic
3457 is returned in present response (and fetch handler is no longer called).
3459 * Minor adjustments to pquery parser (PQF). Token characters may be
3460 escaped by using backslash (C-style).
3462 PQF parser allows string attribute values to be specified. For @attr,
3463 non-numeric characters after the equal-sign are treated as strings
3464 (e.g. @attr 9=title).
3466 CCL trunction character may be defined (@truncation in file)
3468 * function zget_ExtendedServicesRequest sets waitAction to
3469 waitIfPossible (was wait).
3471 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3474 CCL operator names may be set in field definition files (CCL_bibset).
3475 See ccl/bib1 for an example.
3477 Fixes in ASN.1 compiler for C++ compatibility.
3479 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3480 and "op_or" to avoid conflict with C++.
3482 Fixed problem with GNU readline detection on Redhat 7.0.
3484 Added step-size for Scan backend handler.
3486 Fixed bug that made the frontend server crash when no attribute
3487 set was specified for scan.
3489 Front-end server automatically switches to original working directory
3490 when installed as an NT service. Previously -w had to be specified to
3493 Added extended attributes for retrieval module (data1), so that data1
3494 records carry d1_readXML/SGML attributes. d1_read also supports
3495 null-data rules ( <tag/>)
3497 On UNIX when POSIX threads are available, a separate library libyazthread
3498 is created. Programmers should link with that library and the yaz library
3499 when using threads. The reason for the split was that some applications
3500 on Linux, such as Apache, doesn't work well when using shared objects that
3503 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3504 (or any frontend server) in SSL mode by specifying ssl: followed by
3505 address. Only tested on UNIX.
3507 Added feature for CCL module. Virtual structure s=al or s=ol generates
3508 and-list and or-list respectively instead of phrase search.
3512 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3513 log_mask_str. This was done to avoid name conflicts with other libraries
3514 (such as other PHP extensions).
3516 Added raw OID member for preferred record syntax (request_format_raw)
3517 and returned record syntax (output_format_raw) for backend fetch method.
3519 Config file yaz-config now accepts options so that it returns specific
3520 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3522 Shared library support for UNIX using GNU libtool.
3524 * Modified backend interface. Request/Response struct's replaced by
3525 one read/write C struct. For example bend_fetchrequest and
3526 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3527 Every handler - even search has to be registered in bend_init
3528 handler. This means that the YAZ library no longer refers to
3529 external functions and it makes it possible to make the whole
3530 thing a single DLL/SO.
3532 Added Segment handler for backend server.
3534 Added Zmbol/Zebra administrative functions to YAZ client.
3536 Threaded frontend server on UNIX (when POSIX Threads are available).
3537 Starting the server with option -T enables multi-threading.
3541 Added configure option --enable-comp/disable-comp to control use
3542 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3543 located in sub directory asn.
3545 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3546 in ${exec_prefix}/bin along with the other programs yaz-client and
3549 GNU automake used to maintain makefiles.
3551 Added several OID's.
3553 Changed retrieval module so that we can load records with no abstract
3554 syntax defined. Tagpaths in these records are fully composed of string
3557 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3561 On UNIX, the generated makefile now supports a proper 'make install'.
3562 The prefix can be set via GNU configure to set the install location
3563 (default is /usr/local).
3565 * YAZ programs client and ztest were renamed to yaz-client and
3566 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3567 locations, such as /usr/bin,/usr/local/bin,etc.
3569 * YAZ Header files were moved from include to include/yaz. YAZ Header
3570 files are referred to as include <yaz/log.h> rather than <log.h>.
3571 The YAZ include path (-I ..) is therefore the same as before. Programmers
3572 should update their #include statements or use -Ipath/include/yaz
3573 instead. The main motivation for doing this change is that YAZ header files
3574 can be installed in "standard" locations /usr/include,/usr/local/include
3575 without introducing conflicts, since ALL YAZ header files are stored
3576 in subdirectory yaz (under /usr/include for example).
3578 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3579 rather than project/workspace files. We switched because project files
3580 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3583 Changed name of logging function, logf, to yaz_log, to prevent name
3584 clash with some math-log functions. The YAZ header log.h defines logf
3585 to yaz_log (#define) so there should be no incompatibilities by this
3588 Added bend_start/bend_stop handlers for server. These handler are
3589 called on start/stop of server. For windows they are called whenever
3590 a service is started/stopped.
3592 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3593 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3594 in util/yc.tcl. The auto-generated C code structures are, in a few
3595 cases, incompatible with the old decoders. There are differences in the
3596 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3597 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3598 The preprocessor variable ASN_COMPILED is defined when the compiled
3599 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3600 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3601 wish to use the old encoders/decoders you can specify --disable-yc
3604 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3605 version so that it supports both new - and old version of DB Update
3607 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3608 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3609 change. The name parameter can be set to 0 in which no name is specified
3610 for the construction. The macros odr_implicit and odr_explicit sets name
3611 parameter to zero for the construction involved. New macros
3612 odr_implicit_tag and odr_explicit_tag are similar to the others,
3613 except that a name parameter is added. For programmers' that don't use
3614 ODR they probably only need to change the call to z_APDU and z_External.
3616 Added access control facility by interfacing the TCP wrapper library.
3617 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3618 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3619 name of the daemon and enables the access control as specified in
3620 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3622 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3623 den Dool <H.M.vdnDool@kub.nl>.
3625 Added reference ID parameter to most functions in server API - refer
3626 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3628 Changed name of ccl library to libccl.a (was ccl.a).
3630 Fixed bug in decoder for Explain (Category TargetInfo).
3632 Added support for GNU readline in client. Thanks to Jacob Poulsen
3633 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3635 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3636 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3637 IMPLEMENTATION! This change was made to the development version before
3638 the ZIG decided to retract the amendment. If any users MUST be
3639 compatible with the original Update definition, PLEASE CONTACT US, and
3640 we will include a separate definition corresponding to the old Update
3641 ES. Note that because of the change to the ASN.1 of the
3642 TaskPackageRecordStructure we cannot define a single structure that
3643 will support both versions.
3645 * Added const modifier to buffer parameter for some ODR/BER encoding
3646 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3647 completeWAIS, odr_dumpBER.
3649 Fixed bug in client.c which caused a crash when a scanResponse didn't
3650 contain positionOfTerm.
3652 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3653 * will cause an error in a client if a non-YAZ target sends both a
3654 * list of Scan entries and non-surrogate diagnostics.
3656 Retrieval module enhancements. Tag sets may be typed in the reference
3657 to it. From the .abs-file the "tagset" directive takes a third optional
3658 integer type for the tag set referenced. From a .tag-file the "include"
3659 directive takes a third optional type as well. The old "type" directive
3660 in the tag set itself is still recognized but acts as the default type
3663 Backend interface change. Individual Scan terms returned from bend_scan
3664 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3665 in include/backend.h.
3667 Retrieval module enhancements. Multiple tag sets and attribute sets may
3668 be specified in abstract syntax specs. Revised the error/warning for
3669 logging messages reported by the retrieval module when reading the
3672 Object Identifier system (oid_..) changed. The API is backwards
3673 compatible but the oid-routines now allocates new OID's when needed.
3674 Raw OID's may be specified in oid_getvalbyname.
3676 YAZ now uses GNU configure to generate Makefile(s).
3678 * Minor changes in some of the member names of DeleteResultSetRequest and
3679 DeleteResultSetResponse. See include/proto.h.
3681 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3682 and added member 'languages' in TargetInfo (which was missing).
3684 Changed the way attribute sets are handled in the retrieval
3685 module. These are now cached, just like the abstract syntaxes
3688 Changed YAZ so that it links with compiled ASN.1.
3690 Added Explain-schema definitions and mapping routines. The following
3691 Explain categories have been implemented: AttributeDetails,
3692 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3694 Fixed minor bug in Windows version of Server Library.
3696 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3698 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3700 Added EXTERNAL: UNIverse Resource Report (non-standard).
3702 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3703 ENUMERATED and SET OF.
3705 * Added 'const' to some of the char pointer arguments for the
3706 functions, data1_read_node, data1_getelementbytagname,
3707 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3710 Fixed bug in data1_insert_taggeddata - the last_child member of
3711 parent wasn't initialised.
3713 * Changed data1_read_record and data1_read_node so that the supplied
3714 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3715 doesn't refer to any parts of the "SGML"-buffer.
3717 Fixed bug in server library (Windows version of statserv_remove).
3719 * Changed code so that it compiles as C++. The type definition
3720 of Odr_fun which is a member of Odr_arm was changed. The result is,
3721 that an explicit typecast is needed for the fun pointer when
3722 using Odr_arm - as in:
3723 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3725 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3727 Implemented the new structured date and time definition as approved
3728 by the ZIG. Added schemaId element to the specificTag in Espec-1
3729 (also approved at the last ZIG). Thanks to RVDM.
3731 Added some Object identifiers (RVDM).
3733 Changed the Update Extended Service (RVDM).
3735 Added command "refid" to client which specifies referenceId for
3736 the following requests.
3738 Implemented extended service handling for server. See ztest.c
3739 for an example as well as backend.h. New handlers are registerd
3740 in the Init handler.
3742 * Changed interface for sort in server.
3744 Added new members to statserv_options_block. It allows a server
3745 to read options from another source than just the command line. Thanks
3746 to Charles Woodfield.
3748 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3749 renamed to zboolean. Some C++ compilers complained about the name.
3751 Minor changes to gils.abs. Added index 's' (sort) on title
3752 and date/time-last-modified.
3754 --- 1.4pl2 1998/1/30
3756 Fixed bug in server library regarding inetd mode (-i). This bug
3757 was introduced by release 1.4.
3759 --- 1.4pl1 1998/1/29
3761 Added sort facility in client and backend server interface.
3763 Fixed problem with dependencies in Makefile(s).
3765 Fixed bugs for encoders/decoders of extended services and
3768 Implemented sub-tree feature for schemas. Sub-trees are
3769 referenced in *.abs-files. See explain.abs for an example
3770 of the use of this feature.
3772 Modified bib1.att; local attributes for ANY didn't include
3773 ANY itself (only affects use of the retrieval module).
3775 Fixed bug in plain SGML reader in function data1_read_node:
3776 tags with prefix "var" was incorrectly interpreted as variants.
3778 Added feature "sub-schemas" to enable references to - and definitions
3779 of - group of elements.
3781 * Removed member parent from type data1_element (in data1.h).
3783 Implemented function odr_nullval() that returns the value of
3786 * Removed member num_children from data1_node (in data1.h).
3788 Made NT service interface part of the server library. The
3789 function statserv_main uses the NT service when required and
3790 calls the statserv_start / statserv_close routines.
3792 Routine zget_SearchRequest and zget_PresentRequest fills
3793 resultSetName/Id member with "default" instead of "Default".
3795 Fixed memory leak in server. Request queue member wasn't freed.
3797 Fixed nmem_exit so that memory is freed.
3801 Revised the CCL parser utility to be thread safe.
3803 Added function, oid_ent_to_oid, to replace the function
3804 oid_getoidbyent, which is not thread safe.
3806 * Added nmem_init and nmem_exit to initialize and release
3807 NMEM resources. Function nmem_init should be called once in the
3808 initial thread before NMEM/ODR is used. statserv.c and client.c
3809 have been changed accordingly. The change was necessary to make
3810 NMEM thread safe. The NMEM memory pool is shared amongst threads
3811 in a process. Unix-based applications will still work fine without
3814 Added NT Services interface for the the Z39.50 (statserv) Server.
3815 Refer to the ztest.c source on the usage.
3817 Windows 95/NT port using MSVC5.0. Project files are included in the
3820 * Defined new 'global' handle for the retrieval (data1) system. The
3821 new handled, data1_handle, describes the state of the data1 system.
3822 This handle is passed as first argument to virtually all
3823 data1 related routines. The functions data1_create and data1_destroy
3824 creates and destroys a data1 handle respectively.
3826 Added ODR encode stream member to all backend request structures
3827 init, search, scan etc. This stream should be used to allocate all
3828 memory used for the response when thread safe operation is needed.
3830 Changed the comstack utility, cs_addstr, to be thread safe. The
3831 returned hostname string returned by the function is now part the
3834 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3835 function. The cs_straddr takes a COMSTACK handle as argument, so this
3836 function must be used after cs_create and before bind/connect.
3837 This function is thread safe.
3839 Moved test server to 'ztest' directory - generic server code still
3840 in 'server' directory.
3842 Made prefix query (pquery.c) utility thread safe.
3844 Added new function modifier YAZ_EXPORT to 'export' public DLL
3845 functions when using windows (see include/yconfig.h).
3847 Added definitions to the OID database (util/oid.c) (RVDM).
3849 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3851 Added call to ccl_rpn_delete in client program.
3853 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3854 release of RPN structure.
3856 Added support for C++, headers uses extern "C" for public definitions.
3857 With input from RVDM.
3859 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3860 Thanks to Ronald van der Meer (RVDM).
3862 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3864 Added support for private extensions to the OID database
3865 (oid_setprivateoids()). Thanks to RVDM.
3867 Added optional, physical ANY (key replication)
3869 Fixed null-reference problem in GRS-1 output filter.
3871 Proximity operator added to Prefix Query Format (PQF).
3873 In test client command "base" accepts multiple databases.
3875 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3879 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3881 Smallish bug-fixes in the new encoders/decoders (explain).
3883 Bug fixed in DeleteRequest.
3885 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3887 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3889 Added SOIF syntax (using private OID for now) to retrieval module and client.
3891 Added Update extended service.
3893 Added SearchResult-1 additional info structure.
3895 Added optional CCL (ISO8777) interpreter as separate module. Available
3898 --- 1.2 1996/6/10 (1st anniversary release)
3900 Added Summary record syntax. Lightly tested.
3902 Added OPAC record syntax. Untested.
3904 Added ResourceReport service encoders/decoders. Untested.
3906 Fixed bug in z_Unit - wrong tagging on unitSystem.
3908 Fixed bug in the DiagRecs decoder.
3910 Added options for max PDU size and session timeout to frontend-server.
3912 Added documentation of query-language parsers and other supporting utilities.
3914 [frontend-server] Added Attribute set to the bend_scanrequest API.
3916 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3917 surrogate diagnostics were generated.
3919 [retrieval] Allow multiple local values for attribute.
3921 [retrieval] Allow multiple attributes per element in .abs files. index type.
3923 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3925 --- 1.1pl2 1996/4/10
3927 Minor changes, mostly specific to Zebra's requirements (retrieval)
3931 Repaired bug in frontend server when running multiple listening
3932 endpoints in dynamic mode.
3934 z_External() now won't break if a known, ASN.1 value comes encapsulated
3935 in an octet-string. The value will pass through unmodified in an Odr_oct.
3937 Added a bit of code to the demo client to decode & display
3938 ASN.1-structured records represented in the octet-aligned branch of
3939 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3941 Added z_ext_getentbyref() to the ASN module. Doc updated.
3943 * Completed the SCAN definition in the ASN module. This may break SCAN
3944 code based on older YAZ-versions at compile-time. The fix is easy -
3947 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3948 under the SCAN definition. Remember to initialize this, server-people.
3950 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3951 that this does not extend to ODR and ASN.
3953 Comstack allows insertion of established socket (primarily for
3954 inetd-operation of servers). Doc updated.
3956 Front-end server can now start from the inetd in TCP mode. Doc
3959 --- 1.0pl4 1996/1/24
3963 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3964 the rank and record number.
3966 Adjustments to the frontend server.
3968 Fixed diagnostic BER dumper. It ignored the file argument.
3972 Various changes to retrieval module.
3974 Changed the union discriminators of the protocol files from enums to
3975 ints paired with #defines.
3977 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3980 *Changed operator in the RPN structure to 'roperator', again to avoid a
3983 Fixed problems in Explain decoders/encoders.
3985 --- 1.0pl2 1995/12/6
3987 Memory bug in log module fixed.
3989 --- 1.0pl1 1995/12/5
3991 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3993 Bug in Explain DatabaseInfo module fixed.
3995 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3999 The shift to v1.0 signals that we now consider the *core* functionality
4000 of YAZ reasonably stable (the core being more or less equivalent to
4001 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4002 tested (Explain not at all - though that will happen soonish).
4004 Minor changes to code to support Windows port.
4006 Various minor changes after we're getting to use GRS-1 & co. more.
4008 Added Espec-1 format.
4010 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4011 of the protocol and it cannot be selected when encoding (maps into 'string'
4012 when decoding). Needed to talk to some servers.
4014 Demo client can request simple element set names.
4016 Added Diagnostic Format encoders/decoders.
4018 Added simple Close handling to frontend server (no hooks for resource
4019 reporting yet), and demonstration client.
4021 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4023 --- 1.0b3 1995/08/24
4025 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4026 handled incorrectly when records were requested in the searchResponse. This
4027 will only affect you if you use the frontend-server.
4029 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4030 Test-client will ask for and print GRS1. Ztest will return dummy records
4033 Added Explain encoders/decoders to the service-level API. Untested.
4035 Added Extended Services: Item Order encoders and decoders to the Service-
4036 level API. Untested. We could use a recent copy of the pertinent bits
4037 of the ILL protocol to add those bits.
4039 Added diagnostic format 1 encoders/decoders to the service-level API.
4042 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4043 odr_cons.c, which causes a more correct output.
4045 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4046 was always set to 0 when no records were requested in the searchRequest.
4048 * Added better external-handling. This shouldn't harm old code that
4049 *encodes* externals. It can break code that looks for a
4050 'single-ASN1-type' representation, since those types that are known
4051 are now decoded immediately. Look at the SUTRS sample code in
4052 seshigh.c and client.c. Documentation updated.
4054 Handling of structured records in bend_fetchresponse. Length -1 marks
4055 structured record, type is deduced from format field.
4057 --- 1.0b2 1995/06/27
4058 Fairly quick maintenance release to add SUTRS support.
4060 Fixed handling of SUTRS records in the demonstration client.
4062 * Added format field to the bend_fetchrequest and bend_fetchresponce
4063 structures of the backend API (frontend server). When the record is
4064 returned, the value of the format field is mapped to an OID. The
4065 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4066 of the record. The special value VAL_NONE in the bend_request means
4067 that no specific format was requested by the client. Documentation
4068 updated accordingly. Test server (ztest) will return a fixed dummy
4069 SUTRS record if your client requests SUTRS.
4071 Documentation updated accordingly.
4073 You can now set external libraries and RANLIB support in the top-level
4077 First public release.
