3 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
5 RPM: do not build with libmemcached support. The libmemcached library
6 on CentOS 5/6 does not work reliably for us (redis to the rescue).
8 configure: only allow libmemcached version 0.40 or later. That's the version
9 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
10 that's not an option, consider redis.
14 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
16 Fix zoom+memcached: present request out of range YAZ-767
20 CCL: add new qualifier r=omiteq which will omit relation=equals
21 for ordered relations. This should be used in combination with either
24 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
26 Solr: simplify yaz_solr_decode_response
28 Solr: use different local var for string manipulation
30 Solr: Get rid of hardcoded limit of extra_args
32 Solr: encode lucene query type YAZ-736
33 Make sure the queries are treated as traditional "lucene", because that's
36 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
40 Build packages for Ubuntu Trusty Tahr 14.04 LTS
42 wrbuf_cstr: fix off by one error.
44 wrbuf_buf: make it always return non-NULL
45 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
49 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
51 zoomsh: offer option -a apdulog
52 As we're used to from yaz-client and GFS based servers.
54 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
55 existing setting apdulog takes effect.
57 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
62 Add re-entrant CQL/Solr/RPN query conversion functions.
63 The re-entrant functions are: cql_transform_r,
64 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
65 These have same functionality as cql_transform,
66 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
67 return the additional infomration as WRBUF to make them re-entrant.
69 Remove CQL to Solr conversion and base solr_transform_t on
70 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
71 data structure as cql_transform_t.
73 cql2pqf utility allows RPN to Solr conversion
75 Fix assert in ZOOM when http connect fails YAZ-757
79 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
81 wrbuf_cstr: make it thread safe YAZ-753
83 yaz_log_init_file may take fd=<no> to open log file at the FD given.
87 Offer new utility function zget_AttributeList_use_string.
89 New conversion step, solrmarc, for record conversion module.
93 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
94 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
99 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
100 The standalone ZOOM sort was completely broken since 5.0.13.
102 ZOOM: generate event Connect rather than None for partial connect
103 (in fact getaddrinfo resolving).
105 ZOOM: only supply clientIP for InitRequest. Rather than for all
108 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
110 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
111 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
112 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
114 New "Facets" section in the documentation.
116 --- 5.0.18 2014/02/27
118 Call exsltRegisterAll in yaz_init_globals, so that all applications
119 using YAZ will have EXSLT things enabled.
121 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
123 Update various URLs to the re-organized SRU pages at LoC.
125 --- 5.0.17 2014/02/26
127 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
128 introduced in 5.0.12.
130 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
131 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
132 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
135 --- 5.0.16 2014/02/25
137 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
139 --- 5.0.15 2014/02/24
141 Fix gcrypt not properly initialized YAZ-740.
143 --- 5.0.14 2014/02/19
145 Describe memcached option for ZOOM.
147 ZOOM: throw present request out of range again YAZ-739
148 Was removed in YAZ 5.0.13.
150 --- 5.0.13 2014/02/18
152 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
153 with localtime_r when threads + fork is used (such as Metaproxy).
155 yaz-config: quote some RHS values (that might include blanks)
157 zoomsh: shows SearchResult-1
159 zoomsh: sortby command
161 zoomsh: use proper list of connections and result sets YAZ-725
163 Avoid yaz_log in sigterm handler for GFS YAZ-737
164 Logging is still performed, but outside sig handler.
166 New ZOOM C feature: result-set caching with memcached. Example:
167 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
169 Remove SSL via OpenSSL support YAZ-732
170 Also deprecate two functions from comstack that aren't working with
171 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
173 Revert "Bison: use %name-prefix directive rather than -p option"
175 --- 5.0.12 2014/01/22
177 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
179 SRU GET/Solr base URLs may hold additional ?args YAZ-729
180 ZOOM option extraArgs already does this, though. It seems useful
181 when dealing with Solr targets to limit by filter, eg.
182 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
184 Remove #fragment for HTTP request encoding YAZ-730
186 Doc: Update list of DLLs/LIBs
188 Doc: update href link to Unix utils and Git.
190 --- 5.0.11 2014/01/15
192 ZOOM: fix "lost connection" problem with servers that uses both squid
193 and another proxy behind it that returns Location headers with relative
196 zoomsh: do not use readline for stdin (no tty) YAZ-724
197 Just use fgets in that case. If the user hits Ctrl-D a new-line
200 zoomsh: empty command ignored YAZ-723
201 rather than performing exit of zoomsh.
203 yaz-url utility offers option -v to enable verbose mode.
205 yaz_url uses yaz_check_location and offers verbose mode.
207 Add new function yaz_check_location.
208 This function gets an absolute URI from Location (HTTP redirect).
210 cookie API: introduce yaz_cookies_reset
212 Update cql.y for newer bison YAZ-720
213 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
214 longer supported. Instead one must use %lex-param and %parse-param .
216 --- 5.0.10 2014/01/09
218 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
221 rpn2solr: support truncation left(2), left&right(3) YAZ-718
223 Mention SRU version 2.0 in yaz-client man page.
227 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
232 Make cs_parse_host public.A
234 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
235 introduced in YAZ 5.0.6.
239 Fix buffer corruption for yaz-ztest record fetch.
243 Allow yaz-ztest to return user-defined records (one record per file).
244 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
246 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
247 Use the stream write instead of odr_printf which has a 4K tmp buffer.
249 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
253 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
254 can read and write this format. For record format JSON, yaz-ztest returns
255 MARC-in-JSON records.
257 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
258 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
262 Improve error reporting for ICU chains YAZ-707
263 Report config element+rule when ICU status is "failure".
265 ZOOM: stop fetching if present response has no records YAZ-710
266 Some targets return less records than their hit count would suggest.
267 This prevents ZOOM from continuing to fetch records if any present
268 response has 0 records in the response.
270 Ensure that GFS calls exit if any listener fails YAZ-710
271 Before, if XML config was in use, it would start the default
276 yaz-ztest: -V shows version (like yaz-client -V)
278 New iconv encoding: danmarc YAZ-692
280 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
282 daemon: only wait for immediate child rather than all children. YAZ-704
284 yaz-client: fix setting of SRU record schema. If scheme was unset, it
285 could lead to invalid memory reference.
289 yaz-ztest returns schema for MARCXML test records. SRU require that
290 recordSchema for records.
292 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
293 instead of non-surrogate diagnostic. This is a per-record failure.
295 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
296 may refer to multiple listeners now. Attribute listenref is a comma separated
299 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
300 option is given for GFS, the dirname of filename (for -f) is used
301 as prefix for options such as cql2rpn, ccl2rpn, etc.
303 Content-Type charset fixes YAZ-701 . Do not inspect charset in
304 Content-Type header for SOAP when decoding SRU. The payload (XML)
305 itself tells what encoding it is. In response, never supply encoding
306 in Content-Type. The response payload (XML) tells what it is (with no
307 encoding in XML it's UTF-8).
309 HTTP decoding: allow blanks in URL paths YAZ-700
313 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
314 and facets. Ensure recordData and recordSchema are always present in
315 record element, because they are required.
317 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
320 Simplify in a lot of places using odr_strdupn.
322 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
326 Increase various buffers in GFS's statserv_options_block
327 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
328 This change makes many type-casts redundant, and, thus simplifies code.
330 Remove last bits of WAIS support.
332 Remove member 'size' from Odr_oct.
334 Slim down the public part of 'struct odr'. Most elements are not part
335 of struct Odr_private.
337 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
338 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
339 In particular facets are supported in both client - and server side.
340 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
341 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
342 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
343 both request/response). This is what a search handler in the GFS
344 will see (regardless of whether operating in SRU mode or Z39.50).
346 Changes to the srw.h (SRU/Solr) definitions include:
347 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
348 (char*), which replace union query and query_type (int). This is because
349 SRU 2.0 supports a queryType parameter. This also means that, to carry
350 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
351 x-pquery=PQFstring (extention parameter). The extension parameter
353 - New element, packing, that has information about SRU
354 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
356 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
358 New element, packing, in Z_SRW_explainRequest.
360 New elements in Z_SRW_scanRequest, queryType and scanClause.
361 These replace query_type and scanClase untion. This is similar to what
364 --- 4.2.69 2013/10/01
366 GFS: log when closing down - at least SIGTERM YAZ-684
367 Also change formatting WRT PID logging a bit.
369 Improve display of MARC records with multi-byte subfield IDs YAZ-695
370 In some rare cases subfield identifiers are multi-byte characters.
371 This will try to deterime length of those and split accordingly.
372 This affects display in line mode as MARCXML/MarcXchange. The encoding
373 of ISO2709 is the same.
375 Change inp argument to const for yaz_read_UTF8_char.
377 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
379 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
381 Better check of marc leader info YAZ-691
382 Problem is that some systems generate MARCXML/MarcXchange with
383 funny headers. These will not work if encoded as ISO2709.
384 Some tests produce new output, due to updated warning messages
386 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
388 yaz-client: display MAB records YAZ-689.
389 Thanks for Heiko Jansen for this patch.
391 New utility z_get_HTTP_Response_server which allows both HTTP server name
392 and HTTP server URL to be given in response.
394 Debian: do not depend on obs tcl8.3.
396 Debian: do not depend on obs libicu36-dev.
398 --- 4.2.68 2013/09/23
400 GFS: pass additionalSearchInfo to search memeber search_input if
401 given. Otherwise pass otherInfo. Request for facets and other search
402 related things will be passed there in future versions of YAZ.
404 New ZOOM setting, authenticationMode, which allows authentication
405 paramters to be encoded in the URL rather than via HTTP Basic auth.
408 rpn2solr: fix nested AND/OR handling. YAZ-685
410 Add comparison routines for some Z-types, such as NamePlusRecord,
411 RPNQuery, Query, RecordComposition and OtherInformation.
413 --- 4.2.67 2013/09/19
415 Don't decode MAB as MARC. Just like we don't attempt to decode
416 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
418 CCL: allow quoted terms for date ranges. YAZ-681
420 Introduce ccl_parser_qual_search. This function makes old function
421 ccl_qual_search, from YAZ 2, available again.
423 Add yaz_facet_list_to_wrbuf. YAZ-683
425 --- 4.2.66 2013/09/11
427 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
428 schema was given for search. YAZ-675
430 Add Solr date range searches. YAZ-621
432 --- 4.2.65 2013/08/22
434 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
436 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
438 ISO2709/MARC parse most octet aligned records; not just those that
439 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
440 MARC parse more records instead of just dumping as is. YAZ-670
442 ZOOM: proper caching for variations of record schema. YAZ-671
444 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
446 --- 4.2.63 2013/07/17
450 --- 4.2.62 2013/07/11
452 New utility z_get_HTTP_Response_details - an extended version of
455 New utility yaz_url_get_error which returns error message of last
456 failed yaz_url_exec call.
458 yaz-url and url functions: allow max HTTP redirects to be controlled.
460 New functions yaz_file_glob2, yaz_xml_include_glob.
461 These functions takes a flags parameter, which, for now only controls
462 whether to fail inclusion of a non-existing file (without glob
463 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
465 --- 4.2.61 2013/06/20
467 For MARC XML parsing, allow record without leader. A fake/default leader
468 is inserted and a warning is tagged with the record.
470 ICU: fix leak in in icu_iter_get_org_info.
472 --- 4.2.60 2013/06/14
474 ICU: fix bug in icu_iter_get_org_info (un-init variable).
476 --- 4.2.59 2013/06/11
478 Implement z_HTTP_header_remove.
480 --- 4.2.58 2013/06/11
482 ICU: Disallow 0 ptrs for some ICU string utilities.
484 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
485 returns original tokens (before normalization).
487 CCL: avoid z39.58/regex truncation when not needed. Apply only the
488 conversion of those masks, when absolutely necessary.
490 CCL: configurable masking character - @mask. Default masking character
493 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
494 full response anyway, so a Transfer-Encoding header will obstruct the
497 --- 4.2.57 2013/05/15
499 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
500 picking a socket. Problem is that some systems has IPV6 support, but
501 we can't create sockets for them, so we pick AF_UNSPEC first.
503 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
504 use content_len to determine resulting Content-Length in HTTP response
505 and NOT Content-Length supplied in headers by user.
507 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
508 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
510 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
513 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
514 with big endian and unsigned char (by default).
516 --- 4.2.56 2013/04/26
518 Fix yaz-client connect (crash in 4.2.55).
520 --- 4.2.55 2013/04/26
522 Fix proxy/host problem for ZOOM that could occur if unix sockets
525 New Debian package libyaz4-dbg.
527 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
528 differently in tcpip_close.
530 --- 4.2.54 2013/04/17
532 Windows installer of YAZ includes YAZ4J as a component.
534 CQL: allow "extra terms" again, by default. Thus, the CQL parser
535 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
536 and earlier. CQL parser may operate in strict mode where queries
537 not conforming to the standard BNF are rejected (syntax error).
538 Whether the CQL parser operates in strict mode is controlled with
539 cql_parser_strict . Strict mode enabled with option -S for utilities
540 cql2pqf and cql2xcql .
542 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
544 --- 4.2.53 2013/04/10
546 New charset, MARC-8c, which is like MARC-8 but allows control characters
547 0x01 through 0x1F, except ESC to be passed through verbatim.
549 Fix a problem with duplicate sub field character in MARC output. Problem
550 happened only when output was MARC-8 encoded.
552 --- 4.2.52 2013/04/03
554 yaz-ztest: Use hash for fake hit count. Before, random number was used.
555 This is problematic for unit tests using yaz-ztest. This patch also makes
556 a hash for CQL queries. For RPN, any term with a leading digit will be
557 treated as pseudu hit count (to force any particular hit count by a client).
559 yaz-ztest: return unique MARC dummy records. Beyond record offset
560 24, the author surname is patched with offset to make all records
563 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
564 on system wide default (/proc/sys/net/ipv6/bindv6only).
565 @4 binds to IPV4 only. @6 binds to IPV6 only.
567 Update CQL API documentation a bit
569 CQL: don't accept extra terms for queries. Makes the CQL parser
570 stricly conformant to the standard.
572 --- 4.2.51 2013/02/12
574 GFS: scan handler gets extra_args from request and may return extra
575 response data . That's for SRU only.
577 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
579 --- 4.2.50 2013/01/30
581 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
583 OPACXML: sync spelling of availabilityDate in XML to that of Schema
584 opaxxml.xsd. The schema had the correct spelling of this member always.
585 The ASN.1 was mis-spelled and still is (API change) - we are
586 not changing this. However, the OPAC to XML conversion had yet
589 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
592 New function, z_ext_record_oid_nmem, which is similar to
593 z_ext_record_oid but takes NMEM rather than ODR
595 --- 4.2.49 2013/01/18
597 ICU: New conversion element 'join' which joins tokens into one
598 with a custom character given by rule attribute.
600 --- 4.2.48 2013/01/10
602 New GFS search member: present_number. This is a hint to the
603 search handler how many records are going to be fetched immediately
604 following search. There's no guarantee that it's going to be the case,
605 since it depends on hit count (for Z39.50 piggyback) and whether errors
608 Make a few functions static (private). The functions getbyte_stream,
609 ungetbyte_stream and yaz_gets are now private. They were never declared
612 yaz-marcdump: exit(5) for serious decoding errors
614 ISO2709 decoding: be more picky WRT header
616 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
617 was only used as to indicate that next-result-set-position should be
619 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
620 Based on patch from Ashley Sanders.
622 Make some functions static/private in PQF parsing. Those functions were
623 never declared in a public header and so should not be in use by
624 applications based on YAZ.
626 --- 4.2.47 2012/11/23
628 ZOOM: special options to control APDU logging.
629 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
630 logging of APDUs until "saveAPDU" option is set again. If logging is
631 already enabled the effect is that current APDU buffer is cleared.
632 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
633 logging (default behavior on new connection).
634 The APDUs sent/received can be obtained by using
635 Using ZOOM_connection_option_get(c, "APDU") or
636 ZOOM_connection_option_getl(c, "APDU", &l).
638 GFS: relay implementation_version from backend
639 From 3.0.40 and later, implementation_version from backend was
640 not used in init response at all.
642 --- 4.2.46 2012/11/15
644 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
645 mode at all. Probably never did.
647 Make a new version of ztest.pem that, at least, is not expired.
649 --- 4.2.45 2012/11/13
651 Fix description of CCL directive 'case'.
653 More tight checking of form arguments (yaz_uri_to_array). Makes
654 YAZ better at rejecting big and/or bad POSTs.
656 SRU decoding does not report more than up to 10 invalid arguments.
658 rpn2cql: less quotes in generated terms. Semantics unchanged, but
659 it's prettier this way.
661 --- 4.2.44 2012/10/25
663 New utility yaz_decode_init_diag. Defined in proto.h.
665 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
666 given for unix local socket.
667 The COMSTACK string for doing so is:
670 unix:/myfile:tcp:localhost:9999/mybase
671 unix:/myfile:localhost:9999/mybase
672 unix:/myfile:http://fakehost/mybase
674 debian: Use dpkg-buildflags in build process.
676 --- 4.2.43 2012/10/19
678 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
679 global's SRU service uses a recordPosition scheme starting from zero.
680 First record's position should be one
681 according to the standard.
683 --- 4.2.42 2012/10/18
685 Allow more namespaces for SRU. This is to allow, for example, an
686 incorrect namespace returned from server
687 http://services.igi-global.com/sru .
689 Minor fixes for compilation on Windows.
691 --- 4.2.41 2012/10/11
693 daemon: log total number of bad signals from child on stop so that it
694 is more easy to spot problems with child worker processes.
696 retrieval: empty backend name attribute omits element set
697 from being used in retrieval.
699 --- 4.2.40 2012/10/04
701 Implement Solr sort strategy "solr", similar to sru11 sorting.
702 This will implement the correct parameters on Solr requst to do
705 --- 4.2.39 2012/09/28
707 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
710 MARC: Extra/missing indicator handled for MARCXML.
711 The indicator length is given in header and is the same for the
712 whole record. If attributes ind1, ind2 are missing, then content
713 character defaults to blank. Extra indicator attributes (beyond)
714 indicator length are treated as an error.
716 Reformat: delete trailing whitespace
718 --- 4.2.38 2012/09/17
720 MARC: fix non-ASCII characters for leader. This is to ensure we can
721 generate XML in UTF-8.
723 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
724 in one node with structure word.
726 --- 4.2.37 2012/09/04
728 yaz-json-parse: JSON output may be pretty printed by using option
731 Increase default value of max message for Z39.50 Init for GFS, ZOOM
732 and yaz-client. Old value was 1 MB. New value is 64 MB.
734 --- 4.2.36 2012/08/22
736 yaz-client: don't display bogus records from SRU servers. Some SRU servers
737 return more records than given by *maximumRecords*. Skipping those in
740 record_render: simplify buffer return handling and fix at least one bad
741 memory reference, that broke the test_embed_record sometimes.
743 Allow http://user:pass@host notation for yaz_url_exec.
745 zoomsh: allow shell command to be executed. Via the system(3) call.
747 yaz_poll: Allow num_fds == 0
749 yaz-client: fix bad encoding of "itemorder item". The itemorder
750 item <no> - command forgot to use length of encoded Item Request
751 package. Error present since YAZ 3.
753 yaz-ztest: fix bad usage of session handle. Bug was introduced when
754 result sets were saved (271a9c83).
756 SRU recordPacking: guess record packing in response rather than looking
757 at the recordPacking element which, OF COURSE, changed semantics in SRU
760 Decode SRU 2.0 responses. The official namespace for responses, according
761 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
762 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
763 nature.com's server, however, usee namespace
764 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
765 we are now using a glob-expr to match up the namespace. ZOOM C and
766 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
767 I can not find a single real example showing the "real" namespace in
768 the documentation from OASIS. The namespace for requests is different
769 from responses, but this is not added to YAZ yet, when we don't encode
772 --- 4.2.35 2012/06/26
774 zoom/record_render: add support for Base64 decoding fo MARC records
775 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
776 which will decode base64 + ISO2709 marc-8 encoded material from text node
779 --- 4.2.34 2012/06/07
781 Add missing definitions ZOOM_resultset_get_facet_field_by_index
782 and ZOOM_resultset_facets_names.
784 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
787 Change APDU dump printing to avoid long leading blanks. For levels 16
788 or larger the level is shown and the indentation is truncated but
789 recursed with modula 8. This makes it still reasonable easy to read
790 - even for nested BER dumps.
792 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
793 return 0 (incomplete package) in case where the BER package was
794 considered too nested (return value of -2).
796 dumpber: lines of level 15 are not indented further. Two spaces per
797 indentation; indentation 15 or more is indented to a fixed indentation
798 and augmented with a level=<no> indication.
800 zoomsh: increase max size of command+args
802 GFS: No limit in RPN buf size in CQL to RPN conversion.
804 --- 4.2.33 2012/05/09
806 New function for daemon utility, yaz_daemon_stop .
808 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
810 --- 4.2.32 2012/04/25
812 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
813 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
815 --- 4.2.31 2012/04/23
817 YAZ daemon utility relays SIGUSR1 to child process.
819 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
820 would result in en empty database list - which in turn would result in
821 encoding failure for search.
823 Fix reading beyond string in yaz_sort_spec.
825 --- 4.2.30 2012/04/11
827 Add two new SRU diagnostics:
828 236: Access to specified database denied
829 1015: Init/AC: Maximum number of simultaneous sessions for Userid
831 Document the very useful ZOOM-C option "apdulog".
833 CQL to RPN: term may be passed through verbatim. This is enabled with
834 truncation.cql . The assumption being that the term is already CQL.
836 --- 4.2.29 2012/03/20
838 record_conv: leader spec may be given for marc element.
839 The leader spec is given as attribute leaderspec for element marc.
840 For example to convert a MARC21 record from MARC-8 to UTF-8:
841 <marc inputformat="marc" outputformat="marc"
842 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
844 record_conv: allow user-XSLT params. For example:
845 <xslt stylesheet="MARC21slim2DC.xsl">
846 <param name="myparameter" value="myvalue"/>
847 <param name="otherparameter" value="othervalue"/>
850 record_conv: fix error handling for missing marc charsets.
852 CQL: fix extra terms in wrong order.
854 --- 4.2.28 2012/03/06
856 record_conv: modify new API for conversion types. The conversion types
857 may be passed in new functions yaz_record_conv_configure_t and
858 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
860 Avoid mixed statement/variable declare; fixes compilation with Visual
863 --- 4.2.27 2012/02/28
865 Add non-standard SRU diagnostic: 235: "Database does not exist".
866 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
867 Update SRU to Bib-1 diagnostic maps accordingly.
869 CCL: add two new diagnostics for unsupported masking. The new
870 diagnostics are: "Embedded truncation not supported" and
871 "Single charcacter mask not supported".
873 --- 4.2.26 2012/02/23
875 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
877 --- 4.2.25 2012/01/11
879 Build YAZ for Ubuntu Oneiric.
881 CCL: allow parantheses for proximity operands. For example CCL query
882 (a) % (b) is now allowed.
884 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
885 marked dead, rather then being destroyed. If not, the session memory is
886 being free'd before the search/scan handler is finished. Also destroy
887 'request' memory in request_release rather than in various places,
888 which resulted in leaks from time to time.
890 --- 4.2.24 2011/12/21
892 cql_sortby_to_sortkeys: honor sort prefix.
894 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
895 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
896 The rpn2cql family of functions now always returns quoted CQL terms.
898 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
900 --- 4.2.23 2011/12/15
902 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
903 sequence is treated as one. For example, &&a=b&&&c& is identical to
906 --- 4.2.22 2011/12/05
908 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
909 APDUs for a connection to a WRBUF.
911 --- 4.2.21 2011/11/23
913 Fix cql_sortby_to_sortkeys. Completely broken before.
915 Make CCL's @truncation work again.
917 --- 4.2.20 2011/11/09
919 New ZOOM connection setting: tproxy. It's like proxy, but does not
920 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
921 to set resolved address + port for a connection outside ZOOM itself.
923 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
925 --- 4.2.19 2011/11/07
927 Fix uninitialized variable in Solr spell support (could cause SEGV
928 for SRU response decoding).
930 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
931 back-end's addinfo through into the ZOOM response addinfo.
933 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
934 they are separated by a colon and a space rather than simply
937 --- 4.2.18 2011/10/28
939 Add support for Solr spell-checking/suggestions through ZOOM.
940 If a Solr target has been configured correctly for spelling-checking
941 and suggestions, these will now be returned on the ResultSet option
942 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
944 --- 4.2.17 2011/09/28
946 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
947 with a flag whether to substitute escape sequences or not.
949 --- 4.2.16 2011/09/22
951 Fix nmem_strsplit_escape to substitute escape char properly.
953 New option for zoomsh -e , which makes it abort on first error and
954 return process exit code to indicate success/failure.
956 YAZ options utility supports special option -- which makes all it treat
957 all following arguments as non-options.
959 --- 4.2.15 2011/09/16
961 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
962 searched if absolute filename is given.
964 Fix conv_xslt() error-reporting when stylesheet is not found.
965 (The value of fullpath is meaningless in this situation.)
967 --- 4.2.14 2011/09/07
969 Fix problem in CQL sort node creation: un-initialized memory.
971 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
972 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
973 CQL sortby depending on whether Type-1 or CQL is actually sent to the
976 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
977 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
979 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
980 will make it possible to use both single-character mask (#) and wildcard (?)
981 in CCL . Throw diagnostic for left truncation because that is not supported
984 --- 4.2.13 2011/09/01
986 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
987 cases using escapes (\-sequences) and masking.
989 PQF parse fix: A trailing backslash followed by end-of-string (\0)
990 would result in a read one byte beyond string.
992 rpn2ccl may use Z39.50 masking for terms (t=z).
994 ICU check fix. Don't include library -lCrun on Solaris, unless present.
996 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
997 not --cppflags (which seeems like an error in icu-config).
999 --- 4.2.12 2011/08/27 RPM package only
1001 cql2ccl: fix conversion of terms: operator characters were not
1004 --- 4.2.11 2011/08/25 RPM package only
1006 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1007 CCL parser will map both # and ? to their regular expression
1008 quivalents (. and .*).
1010 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1011 of reserved CQL characters.
1013 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1014 is, so that they are passed through.
1016 --- 4.2.10 2011/08/24
1018 ZOOM SRU mode: more aggressive re-connect.
1020 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1021 made available as a utility function, declared in <yaz/logrpn.h>
1023 rpn2cql_structure() supports proximity nodes (except that the Type-1
1024 proximity node's "exclusion" binary is ignored, as there is no way to
1025 express that in CQL). Fixes bug #4564.
1027 --- 4.2.9 2011/08/18
1029 Fix SEGV that could occur if set command of zoomsh was given without
1030 value (2nd argument).
1032 Fix SEGV that could occur if unsupported transport was given for
1033 COMSTACK - say https (when SSL was unavailable).
1035 Build yaz-url on Windows too.
1037 --- 4.2.8 2011/08/11
1039 New utility to get web content. Header is url.h. A command line tool
1040 yaz-url is part of the distribution and packages.
1042 Fixes for SSL COMSTACK (when gnutls is in use).
1044 New functions yaz_base64{encode,decode}. Header is base64.h.
1046 --- 4.2.7 2011/08/03
1048 ZOOM C includes HTTP response buffer as additional info if it fails
1049 to decode the SRU response.
1051 Make wrbuf_json_puts available.
1053 --- 4.2.6 2011/07/28
1055 zoom: throw diagnostic for invalid value for option "sru". Before a
1056 bad SRU request was sent.
1058 Adding new utility wrbuf_vp_puts.
1060 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1062 --- 4.2.5 2011/07/21
1064 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1065 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1066 redirect was used at the same time.
1068 MARC line mode decoding: be less picky about length given - first
1069 5 digits of header that is.
1071 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1073 Changes to decoding of SRU records: a record with recordPacking=xml is
1074 modified with a new root element <yaz_record> if the recordData contains
1075 multiple children elements. This is to make the record XML parseable
1078 RPN to Solr conversion: encode special characters.
1080 Generic Frontend Server: fix uinitialized member, stepSize.
1082 --- 4.2.4 2011/06/21
1084 Fix a bug in SRU decoding of records.. The database records stored
1085 had un-initialized memory, but it would only be seen with yaz_record_render
1086 and type_spec="ext" .
1088 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1090 --- 4.2.3 2011/06/17
1092 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1094 --- 4.2.2 2011/06/10
1096 Add new utilities to convert from CQL to CCL . These utilities have
1097 prefix cql_to_ccl defined in cql.h.
1099 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1100 lead to memory heap corruptions when ICU utilities were in use.
1102 --- 4.2.1 2011/06/07
1104 Make compilation work without Libxml2.
1106 yaz-client: remove redundant blanks in display of searchResult-1 term
1109 --- 4.2.0 2011/05/18
1111 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1112 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1114 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1115 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1116 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1117 Note that the CQL sortby spec is only converted when the GFS is already
1118 converting from CQL to RPN (cql2rpn element).
1120 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1121 specify whether to collapse delimitors or not. The existing nmem_strsplit
1122 do collapse (collapse parameter = 1).
1124 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1126 Rename internal func yaz_use_attribute_create. While non-static, this
1127 function is not declared in a public header.
1129 --- 4.1.7 2011/03/15
1131 Add -lCrun when linking with ICU on Solaris.
1133 More quicks character set conversions for OPAC records.
1135 --- 4.1.6 2011/03/10
1137 fix problem with record_render: records were converted (character set
1138 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1140 --- 4.1.5 2011/03/08
1142 SRU: add methods for handling DADS SRU-proxy facets.
1144 Separate OPAC record character set for ZOOM_record. yaz_record_render
1145 allows a character set given as charset=from/opacfrom,to where 'from' is
1146 the character set of a bibliographic record, 'opacfrom' is character set
1147 of OPAC record and 'to' is the target character set.
1149 --- 4.1.4 2011/02/21
1151 yaz-client: show may XML format records. Command show followed by 'format'
1152 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1155 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1158 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1160 --- 4.1.3 2011/01/27
1161 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1163 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1164 this package can be distinguished from other vendors.
1166 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1167 as determined by configure
1169 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1171 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1172 returns no error and no record, the present request is considered
1173 partial (only a subset of the records could be returned by backend), and
1174 so it is appropriate to set Present Status to partial-4.
1176 --- 4.1.2 2010/11/02
1178 Move yaz-config man pages to section 1.
1180 More documentation about Solr.
1182 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1183 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1184 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1185 peers on some Linux systems. However, in general that does not work
1186 so YAZ can not rely on that to work. Debian changed behavior in this
1187 respect from Debian lenny to Debian squeeze (still testing as of Oct
1189 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1191 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1193 --- 4.1.1 2010/10/05
1195 Fix yaz-config output: echo_source not set correctly by configure.
1197 --- 4.1.0 2010/10/05
1199 Solr Web Service support for yaz-client and ZOOM.
1201 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1203 --- 4.0.12 2010/08/17
1205 Z39.50 facet support. Facet specifications are passed for search in
1206 other-information with ASN.1 as defined in facet.asn and OID
1207 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1208 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1209 3 is limit (number of entries to get in response). yaz-ztest returns
1210 dummy facets if a client asks for them.
1212 --- 4.0.11 2010/07/09
1214 CCL fixes: bug 2895 and bug 3539.
1216 GR1-display: add comma in display - was removed by mistake in
1219 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1221 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1223 --- 4.0.10 2010/06/18
1225 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1226 result set from a connection. The result set will be on its own
1227 thereafter; no operations on it will perform retrievals from a target.
1228 Only cached copies are returned.
1230 ZOOM C:fix case for HTTP servers responding with Connection:close.
1231 Ensure that if there is a current task it is resumed (like fetching
1232 more records in a result set) . Bug #3484.
1234 PQF parser: use odr_atoi for Odr_int (not atoi)
1236 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1237 values that contain any non-digits are treated as string attributes
1238 (previously decoding only checked for leading character ([0-9]). PQF
1239 encoding: attribute string values are not surrounded by double-quotes.
1241 --- 4.0.9 2010/05/21
1243 New utility for managing threads - thread_create.h.
1245 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1246 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1247 but YAZ' implementation do.
1249 Fixes for yaz_cond-functions on Windows 7.
1251 DLL export more symbols.
1253 zoomsh: show record do NOT render opac.
1255 Remove *.la files from Debian and RPM packages.
1257 --- 4.0.8 2010/05/11
1259 Debian package libyaz-dev depends on libgnutls-dev again (was
1260 removed in YAZ 4.0.6, but due to Libtool it is still needed
1261 even though yaz-config do not list libgnutls libs).
1263 ZOOM: Use only one WRBUF for returning string results for
1264 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1266 ZOOM: ZOOM_connection do not use a shared pointer to
1267 ZOOM_resultset after ZOOM_resultset is destructed by
1268 user. Reverts to YAZ 4.0.4 behavior.
1270 --- 4.0.7 2010/05/04
1272 record-conv: fix problem with at least one XSL conversion -
1273 due to probably incorrect usage of XML XSL documents.
1275 --- 4.0.6 2010/04/29
1277 Fix yaz-config for static mode and the use of SSL (gnutls).
1279 --- 4.0.5 2010/04/29
1281 Forward decl timeval struct in mutex.h and gettimeofday.h.
1283 yaz-config: fix 'static' mode linking.
1285 --- 4.0.4 2010/04/28
1287 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1288 are wrappers for pthreads or Windows. For Windows these are put in
1289 a separate DLL: yaz_cond4.
1291 libyaz.la (whole source) is compiled with thread. If thread support
1292 is enabled enabled, all source of YAZ is compiled with treading support.
1293 This allows core utilities such as yaz_log to use thread facilities.
1294 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1295 thread utilities. This commit moves mutex utilities (mutex.c) from
1296 libyaz_server.la to libyaz.la.
1298 yaz-json-parse displays leading text until error.
1300 --- 4.0.3 2010/04/09
1302 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1303 patch from Giannis Kosmas.
1305 SRU: no longer URL encode SRU database. The URL for an SRU server is
1306 a URL and such is alreeady encoded - at least when given with leading
1307 http:// or https://. This reverts behavior to YAZ 3.0.50.
1309 Support for new MARC XML notation TurboMARC which like MARCXML is a
1310 complete representation of MARC/ISO2709.. This one, however, is more
1311 compact and allows for faster processing with XSLT. TurboMARC can be
1312 used in the marcdisp.h API, from the yaz-marcdump utility and from
1315 yaz-ztest can be configured - via the database - to perform certain
1316 delays when it performs operations search, present and single record
1317 fetch. This allows testers to make yaz-ztest act as a real or even slow
1318 Z39.50 server. Refer to the yaz-ztest man pages for details.
1320 --- 4.0.2 2010/03/09
1322 wrbuf_destroy allows NULL WRBUF passed to it.
1324 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1326 Add ZOOM_connection_close.
1328 No fixed size buffers for ZOOM shell - bug #3257.
1330 tstodr: make it work on s390 platform.
1332 New icu iterator-functions. The new icu_iter-functions makes it possible
1333 to use ICU chains from many threads.
1335 yaz-client: better syntax check for show command.
1337 --- 4.0.1 2010/01/26
1339 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1342 New simple local-file XML include facility which allows file glob-patterns.
1343 Refer to yaz/xml_include.h.
1345 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1348 ZOOM_record_get supports new parameter "format" which makes it format XML
1351 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1352 JSONText in ECMA-262) is JSONValue, not JSONObject.
1354 --- 4.0.0 2010/01/20
1356 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1357 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1359 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1360 POSIX/Unix builds .so with major version 4.
1362 Remove old LOG_-defines from log.h. They have been obsolete and
1363 undefined by default for the last 5 years.
1365 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1367 GFS: Remove socket (int *fd) from search_rr handler. The socket
1368 descriptor ptr is a facility that allowed a search handler to supply
1369 a socket which would serve as a callback - when search was complete.
1370 This facility has now been in use for years.
1372 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1373 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1374 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1375 returns 'const char *' rather than 'char *. The returned string is
1376 read-only and should not be modified by applications. COMSTACK cs_close is
1377 now a void function - it no longer returns int. No applications check for
1378 the value and the implementations has always returned 0.
1380 ZOOM: use size_t for scan hit counts and str size. Functions
1381 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1382 occ (hit count) and len (string length) are now of type size_t pointer
1383 rather than int pointer. This is to be able to represent large hit counts
1384 and to also just to use the proper type for string length (strlen result).
1386 New JSON parser. Refer to include/yaz/json.h .
1388 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1389 Used to be int in some cases. Many wrbuf_-functions used to return an int
1390 indicating some length.. These return values were never used. And so they
1393 ODR: odr_malloc, odr_total now takes size_t for size.
1395 clone_z_type: fix leak; occurred for encoding failures.
1397 --- 3.0.52 2009/12/03
1399 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1400 bug was introduced in 3.0.51.
1402 --- 3.0.51 2009/12/02
1404 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1406 tcpip comstack: fix leak for getaddrinfo.
1408 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1409 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1410 Decoding of SRU "path" database is performed by private function
1411 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1412 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1414 yaz-client: honor base command for SRU. Change when database setting
1415 is applied for SRU and ensure it is kept when a connection is reset.
1416 Change also the way errors are displayed or SRU (decoding of packages).
1418 --- 3.0.50 2009/11/02
1420 Add support for extra request / response data for SRU codecs and GFS.
1421 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1422 for extra data response buffer and length. For the GFS, both request
1423 and response data (XML) is carried in extra_args and extra_response_data
1424 for the search handler. Patch by Ko van der Sloot.
1426 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1427 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1428 10010). This fixes bug #2113.
1430 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1431 cmdfile included a 'quit' command that would result in a memory violation.
1433 --- 3.0.49 2009/10/01
1435 Make a number of functions defined in xmlquery.c static. These have
1436 never been declared in a public header file (yaz/xmlquery.h) and was
1437 made public by mistake.
1439 Improve speed of character conversions (iconv utilities). This makes
1440 conversions from MARC-8 faster.
1442 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1443 unless type desired is "raw". This will prevent type "xml" from
1444 returning ISO2709 .. Which obviously can not be XML parsed.
1446 Fix memory leak in ZOOM that would occur if option apdulog was used
1447 on a re-used connection.
1449 Frontend server logs HTTP requests.
1451 Frontend server now sends Z39.50 close when it times out (sesssion has
1452 been idle for too long). Versions 2.0.30 and earlier also sent close.
1453 But due to a mistake this was disabled in all versions after that, i.e.
1454 the server would just close the socket immediately.
1456 yaz-client emits a better message when receiving an unrecognised
1457 userInformationField.
1459 Skip zero-length subfields when decoding ISO2709. This rare case happens
1460 if a record has two FS characters in a sequence. Without this patch
1461 there would be a reference beyond char array in using_code_len fragments
1464 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1466 --- 3.0.48 2009/08/28
1468 The show command offered by the zoomsh command now takes a 3d optional
1469 parameter type which is what is passed to ZOOM_record. If the type
1470 argument is omitted, "render" is used.
1472 RPN to CQL conv may use USE string attributes (bug #2978).
1474 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1476 --- 3.0.47 2009/07/08
1478 Function yaz_xml2query allows a diagnostic element in the PQF XML
1479 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1480 code and additional info respectively.
1482 The BER BOOLEAN is now the integral type Odr_bool which still happens
1483 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1484 typedef'd to Odr_int. This is still an integral 'int', but it may be
1485 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1486 ASN-1 compiler as well as programs has been updated to use the new types.
1488 --- 3.0.46 2009/06/08
1490 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1491 only the bibliographic record was rendered. For type=opac, an OPAC
1492 record is only returned if it is present.
1494 iconv: small fix for encoding of advancegreek.
1496 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1498 yaz-client: option auto_reconnect=on really reconnects.
1500 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1502 server: avoid null ptr ref for for yaz_poll errors.
1504 build: fix RPM build for RHEL 5.3.
1506 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1508 --- 3.0.45 2009/03/31
1510 Fixed bug #2709: TCP connect returns Invalid argument.
1512 Fixed compilation for mingw.
1514 Honor charset for raw records (ZOOM_record_get).
1516 Fixed use of errno for threaded mode that was seen on Solaris 10.
1518 Fixed argument passing with blanks in value for Windows Service.
1520 Disable YAZ' own log rotate by default (no 1 GB limit).
1521 The variable l_max_size which specifies the log file limit is set to 0
1522 (DISABLED): This is due to the fact that YAZ is most often deployed using
1523 logrotate. Also YAZ can not perform log rotate because of unsufficient
1524 permissions (setuid).
1526 --- 3.0.44 2009/02/17
1528 List supported encodings in man page for yaz-iconv.
1530 Fixed missing SSL libs for --libs output
1532 Re-established OID record syntax application-xml. Nobody should use it
1533 but we don't want to change soname because of this symbol being absent.
1535 --- 3.0.42 2009/02/02
1537 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1539 Added member named_result_sets for init handler struct for the GFS. This
1540 allows a server to disable named result sets.
1542 Removed OID record syntax application-xml.
1544 Added support for rule-based transliterator for ICU wrapper of YAZ.
1546 Fixed bug #1902: yaz-icu XML output.
1548 Make YAZ checks Emacs friendly.
1550 BITSTRING value shows value. Bug #2346.
1552 ISO2709 decoding: skip control characters from indicator data.
1554 Omit sort key by default in yaz-icu's output.
1556 Allow combined single char options (again) for YAZ' options function.
1558 Utility yaz-marcdump got option to display YAZ version (-V).
1560 Allow YAZ to use ICU 3.4.
1562 Added new ICU test case which illustrates removal of diacritics.
1564 --- 3.0.41 2008/12/29
1566 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1568 --- 3.0.40 2008/12/29
1570 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1573 Fixed bug #2352: yaz-marcdump crashes for certain record.
1575 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1577 Added support for Danmarc2 to UTF-8 conversion.
1579 Added support for ISO5426 to UTF-8 conversion.
1581 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1582 implementation version.
1584 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1586 --- 3.0.38 2008/11/10
1588 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1589 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1591 ZOOM C now interprets databaseName option for ZOOM connection as path
1594 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1596 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1598 Dummy Libxml2 types no longer defined in headers of YAZ'.
1600 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1603 --- 3.0.36 2008/09/26
1605 Various ODR chapter fixes.
1607 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1609 Added missing source for Windows compilation, mutex.c.
1611 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1613 For SRU connections in ZOOM all records up to "count" are now fetched.
1615 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1616 in Windows due to bad error handling for Libxml2.
1618 Added facility for sending arbitrary records (ASN.1 any) using
1619 ZOOM C's Extended service update. Patch by Sam Reynolds.
1621 New options for ZOOM C's connection, logapdu which makes ZOOM log
1624 --- 3.0.34 2008/06/18
1626 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1628 --- 3.0.32 2008/06/12
1630 Fixed memory violation that could occur when decoding UTF-8. This bug
1631 was only present in 3.0.30 of YAZ.
1633 --- 3.0.30 2008/06/06
1635 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1636 GNU TLS is used by default (if found).
1638 yaz-ztest returns OPAC records if a client asks for OPAC.
1640 Improved speed of MARC-8 encoding.
1642 Added support for lossy and loss-less MARC-8 encoding.
1644 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1646 Added new Windows Service wrapper (sc).
1648 yaz-client's itemorder command may now send a file.
1650 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1652 Added new function yaz_log_xml_errors.
1654 Allow (but warn) unknown XML attributes in MARCXML parsing.
1656 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1658 The UTF-8 to MARC-8 conversion now uses a different set of characters
1659 for Greek symbols. Bug #2120.
1661 --- 3.0.26 2008/02/21
1663 Added yaz_daemon (daemon.h).
1665 Fixed bug #2068: pkg-config trouble
1667 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1669 --- 3.0.24 2008/01/28
1671 Document --with-xml2 option.
1673 Added OPAC XML XSD (etc/opacxml.xsd).
1675 Allow glob mask for name attribute in retrieval element for the
1676 generic frontend server's retrieval facility.
1678 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1679 except POLLIN/POLLOUT.
1681 Fixed error handling in cs_listen. Bug #2037.
1683 --- 3.0.22 2008/01/20
1685 Fixed version in yaz/yaz-version.h.
1687 Fixed bug #2027: Crash when closing connection.
1689 Changed configure so that ICU support is only enabled if only ICU
1690 and Libxml2 is available (because the ICU chain is XML based).
1692 --- 3.0.20 2008/01/15
1694 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1695 is built. Only this DLL depends on the ICU runtime.
1697 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1698 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1700 Changed license of CCL module to 'Revised BSD'. After consultation with
1701 remaining members of the original EUROPAGATE consortium, we are re-issuing
1702 the CCL module without a separate license. The software was developed by
1703 Index Data as part of a research project. The special license was included
1704 to help feed usage information back to the project consortium to support
1705 project evaluation. At this time, the project consortium has long-since
1706 disbanded, and the majority of the original principals have retired. At the
1707 same time, we have significantly modified the software during the following
1708 years, to the point where very practically no original code remains. To
1709 simplify re-use of the software, we have contacted those members of the
1710 consortium who could be reached, and agreed to re-issue the module as a
1711 proper part of the YAZ package.
1713 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1715 CQL closer to being version 1.2 compliant. CQL also allows free-form
1716 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1719 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1720 bug could make Extended services handling crash in the ZOOM layer. This
1721 bug was only present in YAZ 3.0.18.
1723 --- 3.0.18 2007/12/19
1725 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1728 yaz-marcdump reads and writes collection wrapped records.
1730 Handle OPAC for record conversion module.
1732 Fixes for ICU wrapper.
1734 Allow ICU libs to be controlled with --with-icu .
1736 --- 3.0.16 2007/11/12
1738 Added yaz_poll which is a wrapper for select/poll. When poll is available
1739 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1740 sockets to be in use.
1742 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1743 functionality through an XML based configuration (ICU chain). This system
1744 is useful for search facilities such as Pazpar2 and Zebra that needs to
1745 perform tokenization of indexed material. The ICU code in a separate
1746 library libyaz3_icu.a.
1748 Added HTTP tunnel facility for COMSTACK, bug #1752.
1749 This is a facility that allows a Web proxy, such as squid, to tunnel
1750 Z39.50 traffic. This facility is "transparent" to must applications
1751 using YAZ. It's enabled by using pseudo transport connect: followed by
1752 the proxy address, followed by command, then follwed by he regular
1753 "virtual" addresss. For example,
1754 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1756 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1758 --- 3.0.14 2007/09/21
1760 Fixed bad memory reference in ZOOM_record - cuased by member not being
1761 initialized. This was a problem only in YAZ 3.0.12.
1763 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1764 fields were not removed.
1766 Changed the way C code is generated from codetables.xml. Made a MARC-8
1767 conversion trie for each characterSet section rather than codeTable.
1768 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1769 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1771 --- 3.0.12 2007/09/12
1773 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1774 from ZOOM_record_error).
1776 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1778 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1780 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1782 Better SRW-to-Bib-1 diagnostic mapping.
1784 ZOOM C and yaz-client announces SRU version 1.2 by default.
1786 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1789 Fixed in yaz_sru_decode to allow other version than 1.1.
1791 --- 3.0.10 2007/08/22
1793 Added support for SRU scan for ZOOM.
1795 Added support for the use of the older versions or Extended Service
1796 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1797 set to the version , 1=first, 2=second, 3=third. The third version is
1798 what ZOOM C has used so far. And that, obviously, is the default.
1800 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1801 therefore in Zebra and in SimpleServer-based applications). The new
1802 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1803 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1804 which is passed into the back-end search callback function.
1806 Added support for HTTP Basic authentication in clients: the SRU/W
1807 codec encodes the username/password elements of the PDU structure
1808 appropriately, and these may be set using the "user" and "password"
1809 options in ZOOM-C applications (the same options that are used for
1810 Z39.50 authentication).
1812 --- 3.0.8 2007/06/25
1814 Fixed bug #1208: SSL appears to be broken in ZOOM.
1816 Fixed bug #1206: Libxml2 include path weirdness.
1818 Added oid_name_to_dotstring.
1820 Allow elementSetName to be specified for ZOOM C record update.
1822 Allow waitAction to be specified for ZOOM C based for Extended Services.
1824 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1825 syntax OID. Bug introduced in YAZ 3 series.
1827 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1829 --- 3.0.6 2007/06/06
1831 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1832 directory. yaz-client now reads commands from file given by option -f
1833 if specified; then tries to read .yazclientrc in current directory.
1834 Failing that, it reads .yazclientrc from user's home directory.
1836 Added support for correlationInfo Note and ID for Record Update via
1839 Added yaz-client command querycharset which specifies character set for
1840 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1841 (termListAndStartPoint).
1843 Charset ISO5428:1984 is an alias for ISO5428-1984.
1845 Implemented a way to perform scan in a result set using Z39.50. This
1846 is achieved by attaching the result set name in the characterInfo
1847 (type InternationalString) of OtherInformation in the Scan Request PDU.
1848 The result set is identified in the otherinformation by the new OID:
1849 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1850 This allows for scan in result set and faceted search . Zebra did some
1851 of this in the APT term using attribute type 8 and value being result
1852 set. Using the OtherInformation approach for this is cleaner and easier
1853 to work with in proxies and the like. This facility can be used in
1854 yaz-client using new command setscan which takes a result set as first
1855 argument, start position (APT) as second.
1857 Changed decoding of SRU XML packed records to deal with servers that
1858 have recordData with XML data with multiple root nodes. Also make
1859 comparison for recordPacking case insensitive. Again, one server
1860 returns "XML" where others return "xml".
1862 For SRU responses allow Content-Type application/xml as well as text/xml.
1864 --- 3.0.4 2007/05/21
1866 Fixed bug in character set conversion of BER strings. Bug introduced
1869 --- 3.0.2 2007/05/08
1871 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1873 For OID class, use oid_class consistently.
1875 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1878 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1879 character set for bibliographic information interchange". By Giannis Kosmas.
1881 Added documentation on new OID API.
1883 --- 3.0.0 2007/05/02
1885 Changes to generic frontend server interface: added new member
1886 'query_charset' for bend_initrequest structure. A backend init handler
1887 should set this member to its native character set for query terms.
1888 When defined, the frontend server logic will announce this character set
1889 to a client if the negotiationModel bit is set by the client. All server
1890 implementors are encouraged to specify this. If a backend server does not
1891 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1893 Added CCL utility to remove terms (stop words) from resulting RPN
1894 tree. This is handled by functions with prefix ccl_stop_words_ .
1896 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1897 terms in RPN queries.
1899 Clean-up the CCL API. Moved some internal structures from ccl.h to
1900 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1901 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1902 This is replaced by ccl_parser_find_str which takes a string instead.
1904 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1905 libyaz.la is the core of YAZ except the generic frontend server and
1906 does not depend on POSIX threads anymore. libyaz_server.la is the
1907 generic frontend server facilities and uses POSIX thread functionality
1908 if available. The libyaz.la no longer depends on POSIX threads because
1909 the number of global structures is limited. NMEM no longer re-uses blocks
1910 between threads ; it simply free's memory immediately but allocates in
1911 "large" chunks as usual. We don't expect any performance penalties
1912 because of this. The yaz_log system is still using a global log_level so
1913 caution must be taken when modifying it with yaz_log_init_.. +
1914 yaz_log_mask_str. This, however, should not cause any trouble because
1915 these functions are called during initialization of application code
1916 anyway. `yaz-config --libs server` returns libs for server applications;
1917 `yaz-config --libs` returns libs for non-server applications.
1919 New OID database - with public definitions in oid_db.h. Removed old OID
1920 database including the head oid.h and definitions such as enum oid_value
1921 and struct oident. The new OID database uses the same string names as
1922 before but the 'protocol' is gone. There are now only two representations
1923 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1924 converts from string to OID; functions with prefix yaz_oid_to_string
1925 converts the other way.
1927 Change to emit_term() in CQL-to-PQF query translation: when a term has
1928 the /regexp relation modifier, do not process it for leading and
1929 trailing "^" and "*", which have quite different meanings in regular
1932 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1933 write handlers no longer carries a 'last' parameter. This will make
1934 yaz_iconv flush "less" characters. A flush is performed by call to
1935 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1937 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1938 removed, because function yaz_query_to_wrbuf does the same.
1940 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1941 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1943 Deprecated MARC utility functions removed.
1945 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1948 Branch split: YAZ_2_1_55_branch
1950 --- 2.1.54 2007/03/16
1952 Fix to ZOOM-C so that transparent reconnection is properly handled on
1953 connections that are in asynchronous mode.
1955 Fixed compilation on OpenBSD 4.0.
1957 Large strings in GRS-1 records are now properly displayed in yaz-client.
1959 Added character conversion support for "advancegreek"; based on patch from
1962 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1963 sequence is met. Before the error was not set so it would be unknown.
1965 Adjust yaz-marcdump MARC reader so that it skips until record separator
1968 --- 2.1.52 2007/03/07
1970 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1971 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1972 fd_set structure used as a bitmask for the FDs to be selected on.
1974 Using ACX_PTHREAD macro to check for POSIX threads.
1976 Fixed have-vsnprintf check.
1978 --- 2.1.50 2007/02/23
1980 Fixes for configure on BSD. Bug #900.
1982 Added snprintf/vsnprintf wrappers for systems that don't have
1983 limits (heavens forbid).
1985 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1986 created before all previous tasks were completed and removed from the
1987 task queue, the new task could be removed by a mistake.
1989 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1991 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1993 Fixed bug #832: Problem with MARC/charset in yaz-client.
1995 Fixed bug #668: save command line history for yaz-client.
1997 Fixed bug #830: pkg-config support.
1999 --- 2.1.48 2007/01/23
2001 Extended ZOOM result set options with two options that may be read by
2002 a client: resultSetStatus and presentStatus with values as specified for
2004 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2006 Fixed bug #827: Using SSL fails on Debian etch.
2008 Fixed bug #826: Weird looking chars for set of MARC records.
2010 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2011 that is treated as an ItemOrder with itemRequest being an XML document
2012 external. The value of "doc" is the content.
2014 Extended the GFS search facility. New member of bend_search_rr
2015 'estimated_hit_count' signals that hits is known to be an estmate
2016 (higher or lower than real hit count). New member 'partial_resultset'
2017 signals that the search was partial (hit count is lower or equal than
2018 real hit count). For Z39.50, the information is stored in resultSetStatus
2019 member of SearchResponse APDU. For SRU, the information is signalled
2020 via SRU diagnostic 59: "Result set created with valid partial results
2023 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2025 --- 2.1.46 2007/01/13
2027 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2029 Added ZOOM_connection_peek_event.
2031 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2032 the following new functions:
2033 ZOOM_event_nonblock, ZOOM_connection_process,
2034 ZOOM_connection_get_{socket,mask,timeout},
2035 ZOOM_connection_fire_event_{timeout,socket}.
2036 The existing blocking event handler, ZOOM_event, is a wrapper for the
2037 + blocking ZOOM_event_sys_{poll,select}.
2039 Implemented function ccl_xml_config which parses XML version of CCL
2040 configuration (bug #798).
2042 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2044 Added timings utility (yaz/timing.h)
2046 --- 2.1.44 2007/01/03
2048 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2051 Fixed bug #779: Rotation of apdu.log fails.
2053 Fixed for character set conversions:
2054 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2055 Honor G1 set in MARC-8 decoding.
2057 --- 2.1.42 2006/12/17
2059 Fixed bug #775: char conversion does not handle Alternative UTF-8
2062 Implemented function yaz_marc_read_line which parses MARC line format
2063 records. There is a wealth of formats out there. So far, this function
2064 reads line records produced by yaz_marc_write_line.
2066 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2067 more generic and easier to remember(!) options: -i format and -o format
2068 which specifies input format and output format respectively - where
2069 format is one of "marc", "marcxml", "line", "marcxchange".
2071 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2072 does not print anything except warnings for records.
2074 For yaz-marcdump, added support for MARC split into files (-s) with a given
2077 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2078 spec, at http://www.loc.gov/standards/sru/record-update/
2079 This has changed the binary layout of the following structs:
2080 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2081 bend_update_rr . Patch by Ko van der Sloot.
2083 Added GFS utility function bend_assoc_is_alive which returns 1 if
2084 association is still alive (client is connected); 0 otherwise (client
2085 closed connection). This allows busy servers to stop working for
2088 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2089 been a separate piece of software. This version of ziffy has been modified
2090 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2092 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2094 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2095 Client code may now interrogate options such as "init_opt_sort" to
2096 find out whether the server claims to support various options.
2098 --- 2.1.40 2006/11/27
2100 Added utilities yaz_{set,get}_esn to set/get element set name from
2103 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2104 of YAZ and has been so since YAZ 2.1.10.
2106 Implemented ZOOM_record_error which returns error information for
2107 record (surrogate diagnostic).
2109 --- 2.1.38 2006/10/31
2111 Updates for SRU Update by Ko van der Sloot:
2112 1. Changed name from "operation" to "action"
2113 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2114 versions in the code, marked as 'backward compatible'.
2115 3. Added diagnostics for SRU Update.
2117 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2119 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2121 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2123 For GFS, fixed problem with SRU diagnostic 'First record position out of
2124 range' being issued for 0 hits.
2126 zoomtst10 part of Windows Build.
2128 --- 2.1.36 2006/10/13
2130 Implemented yaz_filepath_comp which splits a path into file path
2131 components (required by Zebra 2.0.3+).
2133 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2134 BSD inspired license until now so this should not have any real impact on
2135 anybody. See http://www.opensource.org/licenses/bsd-license.php
2137 Fixed bug #687: Missing log lines.
2139 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2142 Fixed bug #689: SRU diagnostics to be added.
2144 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2145 whether a connection is idle (no more work do do).
2147 --- 2.1.34 2006/10/04
2149 Change type of optval from long to int for invocation of setsockopt with
2150 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2152 Added support for specifying the max log file size for the Generic
2153 Frontend Server. The size is given with option -r.
2155 --- 2.1.32 2006/09/21
2157 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2159 --- 2.1.30 2006/09/17
2161 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2164 Fixed bug in Generic Frontend Server that could cause a server to stop
2165 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2167 For the generic frontend server, the maximum record size is used as maximum
2168 size of incoming packages (SRU + Z39.50). The value until was previously
2169 only used in Z39.50 Init negotiation and, later, in a session controlled
2170 sizes of records returned. This is controlled using -k option. It can be
2171 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2173 --- 2.1.28 2006/09/04
2175 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2178 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2180 New option for yaz-marcdump -lpos=value which allows setting a portion
2181 of MARC header to a certain value.
2183 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2185 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2186 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2188 --- 2.1.26 2006/08/15
2190 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2193 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2195 --- 2.1.24 2006/08/08
2197 Fixed MARC ISO2709 encoding routines to deal with character set
2200 Minor changes to GFS logging. Database included in search request log
2203 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2204 cached/multiple records.
2206 Shared libraries are built by default on Unix+configure.
2208 Changed cql2pqf transformation to use a different evaluation order. The
2209 new order is: always, relation, structure, position, truncation, index
2210 and relationModifier. Old order was: always, relation, relationModifier,
2211 structure, index, position, truncation. Note that the the latter ones
2212 override former ones for identical attributes.. The new scheme means that
2213 it is possible to override any existing attribute with a relationModifier.
2214 And also that it is possible to override everything for the index rule
2215 (except the ones listed in relationModifier). No order is perfect but this
2216 one, we believe, covers more real cases.. The "always" should have been
2217 called "default", since the attributes there can be overridden with all
2220 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2221 compilation phase, but also for yaz-config --cflags output. This allows
2222 us to have public headers with Libxml2 stuff in them . It should also,
2223 eventually, make Libxml2 checks redundant in packages using YAZ, such
2226 --- 2.1.22 2006/06/15
2228 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2229 stored in uri, message and details.. Previously diagnostics were stored
2230 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2231 compatibility.. but he's probably the only one affected, so.
2233 Added support for CCL, compiled on the client side, in ZOOM-C. This
2234 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2235 input; the resulting query objects can be used for for searching with
2236 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2238 YAZ' configure searches for OpenSSL by default.
2240 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2241 SL_CTX_use_certificate_file. See
2242 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2243 for more info. Thanks to Ko van der Sloot.
2245 --- 2.1.20 2006/06/02
2247 Bug #600: SRU GET, POST support for yaz-client. Introduced
2248 command 'sru' which selects method SOAP/GET/POST.
2250 Allow missingValueAction to be specified for the sortspec string -
2251 function yaz_sort_spec. By default, the missing value action is null.
2252 Use ! to specify "abort". Use = followed by stringvalue to specify default
2255 Ensured that Present-handler (if defined) is called in GFS before any call to
2256 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2257 searchRetrieve requests.
2259 Documentation for YAZ is now based on the Docbook XML/XSLT using
2260 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2261 is no longer depending on jade/openjade or docbook-to-man scripts.
2262 PDF is no longer part of the distribution - but can optionally be
2263 made using DSSSL/jadetex or FOP.
2265 Added retrieval handling support in Generic Frontend Server to support
2266 conversion between MARC/XML as well as XSLTtransforms. See
2267 etc/yazgfs.xml for an example.
2269 Added Authentication support to Generic Frontend Server in SRU
2270 mode. Authentication using HTTP Basic is supported, as is the use
2271 of 'x-username' and 'x-password' parameters in the request itself.
2273 Added support for a new character set MARC8s identical to MARC8 except
2274 that it converts combined characters to single Unicode characters in the
2275 Latin-1 range (when possible).
2277 --- 2.1.18 2006/04/24
2279 ASN.1 compiler 0.4: generates brief Doxygen file header for
2280 generated .h/.c files.
2282 Utility yaz_iconv now supports conversion to MARC-8.
2284 New facilities for the MARC module. The reading - and writing of
2285 content are separate methods for the yaz_marc_t handle. The following
2286 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2287 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2288 format). Write functions have prefix yaz_marc_write_.. The existing
2289 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2290 available. Removed support for OAI-MARC and simplexml (not the
2291 simplexml from PHP5).
2293 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2294 to be returned for this connection.
2296 --- 2.1.16 2006/03/31
2298 Allow multiple languages and charsets to be specified with
2299 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2300 negcharset iso-8859-1,utf-8
2302 Translation of proximity nodes from CQL into PQF now works.
2304 Moved to automake 1.8, 1.9.
2306 Added function yaz_log_set_handler which allows a log handler to be
2307 installed. This handler will be called for all log messages. Output
2308 to file is also produced; but that can be disabled by passing NULL
2309 fname to yaz_log_init_file.
2311 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2313 For SRW (including GFS), accept application/soap+xml as content-type
2316 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2317 produces NO stylesheet reference even if a default stylesheet is specified
2320 --- 2.1.14 2006/03/14
2322 Updated Windows package to include yazd.dll + yazd.lib for the
2323 Development component.
2325 If the environment variable YAZ_LOG is set, then it is used as a
2326 string indicating the default level of logging to use if not
2327 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2328 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2329 used as before. So, for example, to omit warnings from YAZ logging,
2330 export YAZ_LOG=-warn
2332 cql_transform() now map structure and other attributes before indexes,
2333 so that index-specific structures and other attributes can override
2334 defaults. So now a combination of mapping specifications such as:
2336 index.dc.date = 1=date-modified 4=5
2337 does the right thing.
2339 cql_transform() now also respects the "always" mapping specification,
2340 which establishes an initial set of attributes to be used for all
2341 terms except where overridden by more specific attributes associated
2342 with the index, relation or modifier.
2344 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2345 which mode to use; one of "post", "get" or "soap" (SRW, default).
2347 Fixes for yaz_iconv routines: changed trie-based character set conversions
2348 to use only non-negative values for bit fields due to Sun's C compiler not
2349 supporting negative values.
2351 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2352 sequences where not read correctly. Fix by Rustam Usmanov.
2354 Updated win/makefile to use options, settings which makes things
2355 compile with VS C 2005.
2357 --- 2.1.12 2006/02/01
2359 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2361 In ZOOM socket code, use select instead of poll on MacOSX.
2363 ZOOM-C now support client-side compilation of CQL into RPN that is
2364 sent to the server, enabling CQL to be used against all Z39.50
2365 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2366 ZOOM_query object, and submit it using ZOOM_connection_search().
2367 The CQL-to-RPN translation uses a configuration file, the name of
2368 which must be specified in the Connection's "cqlfile" option.
2370 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2371 function, which takes as its start-term parameter a ZOOM_query object
2372 (which may have had either CQL or RPN set into it).
2375 --- 2.1.10 2005/11/29
2377 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2378 GFS to support this as well. Backend handler, bend_srw_update, does the
2379 update work. Code contributed by Ko van der Sloot.
2381 Allow retrieval of Search Result-1 information in ZOOM by the use of
2382 options that are attached to a result set. ZOOM documentation updated
2385 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2386 UTF-8 conversion. Patch by Raj Patel.
2388 Added option -m to GFS to control formatting of timestamps in log file.
2390 Added 'exit' as synonym for 'quit' in yaz-client
2392 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2393 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2394 for the new members. Patch by Ko van der Sloot.
2396 Added support for SRU POST. It is supported for content-type
2397 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2399 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2400 Instead make the library libyaz.la multi-threaded. Threading as a whole
2401 can still be disabled by configure option --disable-threads. Previosly,
2402 with older GLIBCs there were problems with MT libs under Apache. This
2403 has now been fixed a long time ago.
2405 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2408 CQL module modified to be case insensitive for relations/indexes/operations.
2410 Fixed bug in CQL transform code: incorrect value relationModifieder
2413 Added 'show all' command for yaz-client which retrieves all results
2416 Added new yaz-client, xmles, which takes a (private) OID and
2417 a document to be sent as an extended service request.
2419 Describe new yaz-client commands wait_response and set_auto_wait.
2421 Increase TCP/IP listener backlog from 3 (which I am guessing was
2422 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2423 that the socket will queue as many incoming connections as it's able
2424 to handle ongoing connections. In other words, it will never now
2425 refuse a connection that it would be able to handle merely because
2426 it's not got around to accepting() enough of the pending connections
2427 yet. This is the behaviour anyway under Linux, where the listen()
2428 argument is ignored; but not under BSD and on systems such as
2429 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2430 YAZ-based servers should now be uniform across operating systems in
2433 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2434 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2435 This allows yaz-marcdump to read large MARC batches (>2 GB).
2437 Modified all YAZ source files - except the source which is auto-generated
2438 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2441 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2442 corresponding to the existing *_setl() function. These allow option
2443 values containing arbitrary valuues.
2445 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2446 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2447 except that it returns an indicator of whether or not the sort
2448 criterion was accepted (0 for OK, -1 for invalid).
2450 --- 2.1.8 2005/06/07
2452 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2453 MARC output rather than returning "new" buffer.
2455 yaz-client warns about unknown init options.
2457 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2459 --- 2.1.6 2005/05/24
2461 Added support for SRW sort in Generic Frontend Server. Patch
2462 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2463 sortKeys - or NULL if none is provided.
2465 Fixed bug #307: It was impossible to specify indefinite/no timeout
2466 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2469 Added support for multiple languages and charsets to be specified in
2470 ZOOM. Each charset/language is separated by a blank. If negotiation is
2471 in effect in init-response, Option
2472 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2473 Code based on patch by Vasiliy Osadchuk.
2475 Fixed bug #306: infinite recursion that occurred when calling
2476 yaz_log_level_init as the first call (before other log level or
2479 Fixed bug in scan handling in front end server: if preferred-Position-In-
2480 Response was non-present, a NULL pointer referece was performed.
2482 --- 2.1.4 2005/04/26
2484 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2485 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2486 now defined for all those error codes. So instead of putting 109 in
2487 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2488 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2490 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2493 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2495 Program yaz-client now exits and produces an error message if multiple
2496 Z39.50 servers are specified on the command line (none or one allowed
2499 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2502 --- 2.1.2 2005/03/16
2504 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2506 Fixed bug #272: Preserve spacing for CCL terms.
2508 --- 2.1.0 2005/03/14
2510 Added support for virtual hosts and multiple backend servers for
2511 the YAZ frontend server. The configution is XML based and
2512 support specificition of CQL to RPN mappings and explain information.
2513 See section "Virtual Hosts" in the YAZ manual.
2515 Extended OPAC display utility. OPAC display utility renders
2516 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2517 to supplement yaz_marc_decode_wrbuf.
2519 Fixed a bug in MARC decoder that could caused it to crash for some
2520 invalid MARC records. More diagnostics and warnings where added in
2521 XML output (warnings, etc are stored in comments).
2523 --- 2.0.34 2005/02/08
2525 Fixes for UNIX domain sockets. Bug #261.
2527 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2529 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2530 Added yaz_marc_subfield_str which defines subfield lead string which is
2531 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2532 yaz_marc_endline_str which defines end of fields string used in
2533 YAZ_MARC_LINE format. Default string is newline.
2535 Experimental support for MarcXChange. This format can be produced
2536 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2537 http://www.bs.dk/standards/MarcXchange.xsd
2539 Added yaz-client commands scansize that sets maximum number of
2540 entries to be returned by scan.
2542 --- 2.0.32 2005/01/11
2544 Added support for SRW scan in yaz-client and Generic Frontend Server.
2546 * Added whereInList member to SRW Scan Term.
2548 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2550 Fixed NMEM system to return aligned blocks on the smallest boundaries
2551 that are suitably aligned for all possible types on the particular
2552 architecture YAZ is being built for.
2554 --- 2.0.30 2005/01/04
2556 Fixed numerious warnings that was issued with newer versions of GCC.
2558 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2559 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2562 Make YAZ Generic Frontend Server slightly faster.
2564 Enhance (and reduce) logging for Generic Frontend Server.
2566 Revert YAZ log system so that it flushes every write operation
2567 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2569 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2570 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2571 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2572 will effectively disable old definitions.
2574 --- 2.0.28 2004/11/09
2576 Added yaz_log_time_format which specifies log format using
2579 Added yaz_log_module_level which returns mask for a module. Value
2580 is non-zero mask a if module is enabled; zero if disabled.
2582 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2583 in include/yaz/cql.h.
2585 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2587 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2589 Fixed bug #172: RPM builds does not enable SSL.
2591 Doxyfile.in part of dist. Doxyfile generated by configure.
2593 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2594 are given and the corresponding component does not exist.
2596 Extend CCL documentation in YAZ reference. Describe r=r.
2598 --- 2.0.26 2004/10/01
2600 Fixed MARC->MARCXML conversion to properly deal with
2601 fields, subfields, indicators having non-ASCII characters.
2603 Fixed MARC->MARCXML conversion so that ASCII control characters
2604 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2607 Added YAZ GFS support for conversion from Z39.50 surrogate
2608 diagnostics to SRW surrogate diagnostics.
2610 Bug fix: YAZ GFS did not return schema in explainResponse.
2612 --- 2.0.25 2004/09/30
2614 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2615 now converts recordSchema to elementSetName as well as schema URI.
2617 Fixed bug in COMSTACK that prevented HTTP request packages from being
2620 --- 2.0.24 2004/09/29
2622 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2623 does not require white-space before and after the dash in a range, e.g.
2624 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2627 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2628 due to new GCC removing "redundant" code.
2630 Added yaz-client commands scanpos and scanstep that sets preferred
2631 position and step-size for scan.
2633 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2635 Added CCL utility ccl_qual_buf which parses one or more CCL
2636 spec lines in a buffer.
2638 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2639 of name and value - ignoring empty lines and comments.
2641 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2643 Added odr_get_element_path which returns current element path for an
2644 ODR handle. This utility is useful in error handling or user-defined
2647 Added ODR_PRINT utility odr_set_stream which is is a more generic
2648 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2649 to a write function and pointer to close function. The close function - if
2650 non-NULL - will be called during odr_destroy.
2652 Fixed bug in CCL parser where truncation char was not removed from
2653 right side when truncation=both was in effect.
2655 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2658 --- 2.0.23 2004/08/11
2660 Fix buffer overrun in CQL parser when dealing with proximity (%).
2662 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2663 to UTF-8/UCS conversion is now only based on codetables.xml.
2665 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2667 --- 2.0.22 2004/08/06
2669 Add support for more "commit changes" in ZOOM (uses Extended Services).
2671 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2674 Yet another small fix for configure of SSL.
2676 --- 2.0.21 2004/05/14
2678 Fix SSL libs for configure when --with-openssl=DIR is given.
2680 --- 2.0.20 2004/05/10
2682 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2684 SSL comstack now uses yaz.pem certificate file on server side
2685 by default. Certificate filename can be configured by calling
2686 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2688 Fix bug regarding multiple calls to ZOOM_connection_connect.
2690 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2692 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2693 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2695 ZOOM now allows inspection of X509 peer certificate for verification.
2696 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2698 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2699 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2700 as "modular" but it simplifies things.
2702 Added cs_get_peer_certificate to that returns peer X509 PEM.
2704 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2705 NULL if SSL is unavailable.
2707 Documentation about MARC decoding tools.
2709 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2711 --- 2.0.19 2004/03/30
2713 Rename CHANGELOG to NEWS to follow GNU style packing.
2715 Fix bug with missing initialization of member in init_diagnostics.
2716 This bug affects threaded version of GFS server.
2718 --- 2.0.18 2004/03/20
2720 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2723 Ensure zlib.dll is packed with Windows install.
2725 --- 2.0.17 2004/03/17
2727 Fix encoding of xsd:string to use text instead of CDATA.
2729 Fix endless loop in CQL parser with unbalanced ".
2731 Use a more compact way to store MARC-8 conversion tables.
2733 --- 2.0.16 2004/03/16 Debian only
2735 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2738 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2743 --- 2.0.15 2004/03/01
2745 Another fix for decoding of XML packed records.
2747 --- 2.0.14 2004/02/25
2749 Fixes for Chunked encoding. White space not ignored after length spec.
2751 Update NS and use default NS for SRW diagnostic elements.
2753 --- 2.0.13 2004/02/23
2755 Implement ZOOM_resultset_cache_reset which resets record cache.
2757 Implement ZOOM_resultset_sort which sorts a result set.
2759 Implement chunked HTTP transfer.
2761 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2763 --- 2.0.12 2004/02/16
2765 Added member 'schema' to bend_explain_rr structure so that backend
2766 can specify explain record identifier. Defaults to Zeerex 2.0.
2768 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2770 --- 2.0.11 2004/02/16
2772 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2775 Added init command for yaz-client which sends "extra" init request.
2777 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2778 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2780 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2782 Make ZOOM error code for "invalid query".
2784 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2786 --- 2.0.10 2004/02/05
2788 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2791 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2793 Added option -p <file> to make Generic Frontend Server to write PID file.
2795 Added option -D to put Generic Frontend Server in background on its own.
2797 Make ZOOM C recognize option "password". If unset, "pass" is used
2798 (for backwards compatibility).
2800 Fixed a bug in Generic Frontend Server that could make it crash if a
2801 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2804 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2805 Must be issued before open, in order to be in effect.
2807 --- 2.0.9-6 2004/01/12 Debian/Windows
2809 Make the SRU server more picky WRT unknown params, etc.
2811 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2813 New YAZ client command, options, that sets Z39.50 options.
2815 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2816 options from a string of tokens (one token for each option bit).
2818 Update SRW diagnostic code messages.
2820 --- 2.0.9-5 2004/01/07 Debian/Windows
2822 Handle user defined stylesheet for SRW/SRU.
2824 --- 2.0.9-4 2004/01/06 Debian/Windows
2826 Fix bug in decoding of Content-Length.
2828 --- 2.0.9-3 2004/01/06 Debian/Windows
2830 Fix a bug with decoding of XML packed records.
2832 --- 2.0.9-2 2004/01/05 Debian only
2834 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2836 Fix bug in SRW/SRU diagnostics decoding.
2838 --- 2.0.9 2004/01/05
2840 Fixed bug in Generic Frontend Server which could drop records exceeding
2841 preferred message size. Reported and fixed by Irina Dijour.
2843 Fixed calculation of package size for structured records in Generic
2844 Frontend Server. Reported and fixed by Irina Dijour.
2846 Fixed namespace for SRW/SRU diagnostics.
2848 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2850 --- 2.0.8 2003/12/22
2852 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2853 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2856 CQL changes to reflect recent changes to the specification:
2857 * Documentation talks about context sets instead of index sets.
2858 * Documentation talks about indexes instead of qualifiers.
2859 * The CQL-to-PQF transformer's configuration file now uses
2860 "index.set.name = <attributes>" instead of the old form
2861 "qualifier.set.name = <attributes>". (Both forms are still
2862 understood but the latter is deprecated.)
2863 * CQL terms with no explicit index specified are now interpreted as
2864 cql.serverChoice instead of srw.serverChoice (which of course
2865 behaves exactly the same.)
2867 --- 2.0.7 2003/12/16
2869 MARC conversion can now generate ISO2709 output in another
2870 character set. yaz-marcdump uses this facility if you invoke it
2873 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2874 functions from there can be used from C++.
2876 --- 2.0.6 2003/12/04
2878 Frontend server now transfers memory from decoded packages to stream
2881 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2882 references to show up.
2884 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2885 the ZOOM Abstract API. The older names for the same options are still
2886 also supported for the benefit of old applications.
2888 ZOOM-C supports "implementationId" and "implementationVersion" options
2889 to go along with "implementationName". These allow the user code to
2890 specify identification strings to be sent to servers.
2891 Add OID for the new ExtLite attribute set.
2893 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2894 as requested/supplid by Ere Maijala <ere@atp.fi>
2896 For generic frontend server, reverse the order of
2897 "toolkit-supplied / application-supplied" strings sent as implementationId,
2898 Name and Version. Also, remove the spaces around the slash. This brings
2899 the GFS in line with the behaviour of ZOOM-C on the client side.
2901 Add function ZOOM_scanset_display_term.
2903 yaz-client shows scan displayTerm if present.
2905 Utility yaz-iconv is now installed by default along with the man page
2908 Extend configure check for OpenSSL to use pkg-config where available (such
2911 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2912 server to specify uid/gid/mask for socket using the format
2913 unix:[user=uid,][group=gid,][umask=mask,]file=path
2914 If file= is omitted the existing format is assumed, e.g.
2916 in which case the mask is 0666 (rw for everybody).
2918 Major restructure of YAZ source. All source in libyaz is in src directory.
2919 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2920 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2922 Added man page for utility yaz-marcdump (used to be called marcdump).
2923 yaz-marcdump is installed by 'make install'.
2925 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2926 of incoming package failed.
2928 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2930 Change prototype of odr_perror: add const to message string.
2932 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2934 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2935 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2936 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2937 DNS lookup. There should not be any compatibility problems with this
2938 assuming that blocking=1 or 0 is used.
2940 Fix bad reference in UNIX comstack in function cs_addrstr.
2942 Fix for compilation on AIX.
2944 The generic front-end server (server/seshigh.c) now supports returning
2945 Init diagnostics to the client in User-information-field, in
2946 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2949 --- 2.0.4 2003/09/04
2951 Allow any CQL relation (not just all,any,exact,scr).
2953 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2954 that features the same UI.
2956 Implemented command update0 in YAZ client which is equivalent to
2957 update but uses old of Ext Update ASN.1.
2959 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2960 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2961 Previously no OID was used for this info.
2963 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2964 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2965 returns 'malformed search term' otherwise.
2967 SortResponse member resultCount now set to NULL in sort handler of
2970 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2973 Add three new utility functions for translating OIDs between various
2974 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2975 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2976 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2977 char *oid_to_dotstring(const int *oid, char *oidbuf);
2978 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2980 Reverted modifications for ES Update definition for z_IU0Update
2981 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2982 is back to YAZ 2.0.2.
2984 String value attributes for CCL parser.
2986 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2987 which their FirstSearch server returns in Init responses, sometimes
2988 carrying useful diagnostic information when Init fails. This has the
2989 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2990 "z39.50/oclcui.asn", where its definition is somewhat different from
2991 what OCLC document on their web-site, as required to interoperate with
2994 Support for anonymous authentication in yaz-client. Use the command
2997 * Fix the OID of the Index Data-local "admin" Extended Service from
2998 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2999 the 1000, which indicates a locally-defined OID, was a mistake.
3001 --- 2.0.3 2003/06/20
3003 Fix CCL directive @case handling so that it affects string match for
3004 both CCL keywords and qualifiers.
3006 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3007 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3008 Decoder has been updated with ASN.1 changes as listed in
3009 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3010 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3011 z_IUUpdate, remains unchanged.
3013 ZOOM_record_get may now return a record in a specific character set.
3014 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3015 "from" is the character set of record as returned by target. "to" is
3016 the character set to be returned. If omitted, "to" is UTF-8.
3018 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3020 New ODR utility, odr_getelement, which returns name of element for
3021 which encoding/decoding failed.
3023 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3024 in cases where a required element was omitted.
3026 Bug fix: some MARC8 sequences were not converted.
3028 New ZOOM option "step" which specifies number of records to be
3029 retrieved in one chunk. Used in conjunction with "start" and "count".
3031 SRW support for yaz-client. Use scheme http: to use it, e.g.
3034 yaz-client no longer does (un)intelligent character set conversions
3035 by default. Can be enabled with charset and marc_charset commands.
3037 xmalloc trace fix for 64-bit systems such as DEC alpha.
3039 Solaris 2.6 compile fix.
3041 New function, cql_strerror() translates SRW error codes, as returned
3042 by cql_transform_error(), into human-readable English strings. Used
3043 in yaz-client diagnostics when appropriate.
3045 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3046 converts it into a type-1 query which is sent to the server. This
3047 makes CQL available for use with all Z-servers, as opposed to the tiny
3048 minority that can handle CQL queries themselves.
3050 --- 2.0.2 2003/04/28
3052 New Debian package layout similar to the Redhat Package layout.
3054 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3055 and search result respectively.
3057 --- 2.0.1 2003/04/25
3059 Redhat package is now several packages: libyaz (runtime libraries),
3060 libyaz-devel (development and documentation, and yaz (utility programs).
3061 Package spec file by Morten Bogeskov.
3063 New member 'schema' in struct bend_fetch_rr which the name of requested
3064 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3065 handler MAY set this to reflect the schema of the returned record.
3067 New member 'display_term' in struct scan_entry. GFS now sets member entries
3068 and allocates scan entries to be filled by user scan handler. In previous
3069 version, entries member was allocated by the scan handler. That still works,
3070 but the GFS will ignore member display_term - assuming it was NOT set by
3071 the handler. The fact that the GFS now allocates the entries both allows
3072 for new members and makes a scan handler easier to write.
3074 Fix CQL lex buffer overflow.
3076 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3077 SRU default recordPacking is string.
3079 SRU protocol support for frontend server.
3081 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3083 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3085 Added scan for the ZOOM shell (zoomsh).
3089 * String Identifers for Schemas (Amendment 5).
3090 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3091 Old definition for schema
3092 Odr_oid *schema; /* OPT */
3097 Z_InternationalString *uri;
3098 #define Z_Schema_oid 1
3099 #define Z_Schema_uri 2
3102 * resultCount parameter to Sort Response (Amendment 1).
3103 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3105 Support for SRW 1.0 over HTTP. This is an optional feature and
3106 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3109 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3110 on the same port. SRW SearchRetrieveRequests are mapped
3111 to bend_init,bend_search,bend_fetch,bend_close.
3113 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3115 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3116 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3118 ZOOM connections are SRW based if schem http is used for hostname
3119 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3120 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3122 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3123 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3124 distance=n, order=true/false, relation=le, prox unit=word. If
3125 n is omitted, distance 1 is used.
3127 Fixed problem with C compiler include path in wrong order.
3129 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3130 on Solaris. Patch from Ko van der Sloot.
3132 New MARC decode API. All new functions operate on a yaz_marc_t
3133 handle. The most important new functions are: yaz_marc_create,
3134 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3135 decode and destroy respectively. Decoder can produce formats
3136 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3137 include/yaz/marcdisp.h.
3139 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3140 to UTF-8, UCS-32, wchar_t or Latin-1.
3142 * Prototypes for yaz_iconv_-functions moved to separate header
3143 include/yaz/yaz-iconv.h.
3145 Make a few private functions 'static' in unix.c. This prevents
3146 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3148 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3149 are set when Init Response is received.
3151 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3152 but returns diagnostic set as well.
3154 New function yaz_strerror which is a portable wrapper for
3155 strerror/strerror_r/GetLastMessage.
3157 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3158 is returned for MARC. If type is "oai", then OAI MARC is returned.
3160 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3163 --- 1.9.2 2002/11/26
3165 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3167 Fix bad race conditions on SIGTERM and terminate gracefully in
3170 Move retrieval (data1) module to Zebra since nobody seems to be
3173 Add GRS-1 render for ZOOM using same format as yaz-client.
3175 --- 1.9.1 2002/10/05
3177 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3179 Fix broken ESpec handling in data1 module.
3181 SGML reader parses comments and makes them part of the data1 tree.
3183 Added several type casts so that YAZ compiles as C++ code.
3185 ZOOM didn't handle PDU encoding failures properly.
3187 Added more Bib-1 diagnostics (approved extensions).
3189 GNU configure: better check for iconv.
3191 More portable use of accept, getpeername. Check for socklen_t. Use
3192 int/size_t if socklen_t is not defined.
3196 PQF parser rejects bad queries - including those with extra
3197 characters in them. PQF parser used to silently ignore that.
3198 Cleaner API for PQF added, which allows you to get detailed
3199 error information for bad queries (see yaz/pquery.h).
3201 Fixed bug in ZOOM_record_get for type "database".
3203 Implemented mini iconv library supporting conversions between
3204 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3206 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3208 --- 1.8.9 2002/08/20
3210 Fixed ZOOM C record cache so that preferredRecordSyntax and
3211 elementSetName is used to check for already fetched records.
3213 --- 1.8.8 2002/08/02
3215 Added three members in bend_initrequest structure to facilitate
3216 character set negotiation.
3218 Fixed a bug in frontend server that could cause indefinite
3219 loops under rare conditions.
3221 Revised character set utilities (charneg.h) so that encoding
3222 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3224 For PQF, directive @term <type> sets term type for Scan/Search.
3225 Here <type> is general, string, numeric, null. The term type
3226 is inherited - just like @attr.
3228 New call odr_set_charset that sets character set conversion for
3229 international-strings on a ODR stream. Prototype is:
3230 int odr_set_charset(ODR o, const char *to, const char *from);
3231 The InternationalString is still represented as C string in YAZ
3232 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3233 won't). On the protocol level, you can use any encoding.
3235 Support for UNIX sockets in ZOOM.
3237 Solaris recv sometimes returns errno == ENOENT. It is treated as
3238 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3240 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3241 both client and server. Code by Morten Bogeskov.
3243 --- 1.8.7 2002/05/22
3245 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3246 that they can be used directly from Visual Basic. You must recompile
3247 your windows APP if you're using ZOOM.
3249 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3250 Commands "lang" and "charset" sets language and character set respectively.
3251 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3252 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3254 Attributes from multiple CCL fields may be OR'ed rather than merged
3255 using directive "@field or". Fields are still merged by default -
3256 equivalent to "@field merge".
3258 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3261 Fixed bug in zget for parameter ExtendedServicesResponse.
3265 --- 1.8.6 2002/03/25
3267 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3269 Client displays USR.1:SearchResult-1 (hits per term).
3271 Additional Search Info for search in Generic Frontend Server.
3273 Fixed CCL parsing of "field=s".
3275 WIN32 installer - using the excellent NSIS software from nullsoft.
3277 Fixed CCL parsing of "field = - <number>".
3279 Added function yaz_marc_decode that decodes MARC for line mode
3280 display or XML (similar to that used by JZKit).
3282 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3283 Z39.50. But ISO/ILL was, however.
3285 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3286 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3288 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3289 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3291 --- 1.8.5 2002/02/03
3293 New YAZ client features: Command completion and new commands:
3294 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3295 Code provided by Jacob Poulsen.
3297 New call oid_trav, that visits all registered OIDs via callback.
3299 Function ZOOM_record_get now returns const char pointer rather than
3300 void pointer. It saves a lot of type casts.
3302 For YAZ client, command "auth" now allows you to set authentication
3303 in IdPass style. It is enabled when three tokens are given - order
3304 is user, group and password.
3306 Fix memory leaks in MARC record handling for ZOOM.
3308 New option for YAZ client, -k <kilobytes> that sets
3309 maximum record size. Similar to -k option for generic frontend
3310 server and yaz-ztest.
3312 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3314 Prefix query parser reports "fail" when bad attribute set is given.
3316 Fix in MARC decoder. Proximity logging. Fix for attribute set
3317 in scan handler for server. Patches by Shigeru Ishida.
3319 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3322 Configure option --with-openssl=<dir> now works when a directory is
3323 specified. Patch provided by Morten Bogeskov.
3325 New option for YAZ client, -u <auth>, that sets authentication.
3327 ZOOM fix: error information was sometimes "missing", since error
3328 was cleared/reset too when it shouldn't.
3330 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3332 --- 1.8.4 2002/01/04
3334 Scan for ZOOM API. New object ZOOM_scanset. New functions
3335 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3336 ZOOM_scanset_destroy.
3338 New ZOOM function, ZOOM_connection_last_event, that returns type
3339 of last event (such as "receive data", "send data", "apdu received",
3342 New ZOOM option, schema, that specifies schema for retrieval.
3344 New CCL feature. Qualifiers can be aliases for one or more
3345 other qualifiers (if more than one is given, OR is used).
3347 ZOOM uses named result sets if target supports it.
3349 Two new YAZ client commands: . (dot, which sources a script of YAZ
3350 client commands), and ! (to execute shell command.). Implemented
3353 Working on Debian packages.
3355 --- 1.8.3 2001/11/19
3357 YAZ client enables named result sets only if target supports it.
3359 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3361 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3362 with key="host" to get same result.
3364 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3365 Function Z3950_resultset_record(s) returns references to records
3366 "owned" by resultset. To become owner use Z3950_record_clone.
3368 Function z_ext_record handles Extended Services. Thanks to
3371 --- 1.8.2 2001/11/12
3373 CCL Parser fix: ignore token comma when dealing with and-lists.
3375 Documentation updates for COMSTACK.
3377 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3378 Changed prototype Z3950_records. For some functions, int parameters
3379 were changed to size_t.
3381 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3384 New MARC decode/display function, marc_display_exl, which properly rejects
3385 non-ISO2709 records. YAZ client uses it.
3387 --- 1.8.1 2001/10/29
3389 Fix bug: local attribute set wasn't set correctly in PQF strings.
3393 * Old Z39.50 codecs no longer supported.
3395 Added ZOOM C binding. See http://zoom.z3950.org/
3397 Renamed states for COMSTACKs to avoid confusion with events.
3399 Implemented cs_look and proper cs_rcvconnect.
3401 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3403 Configure detects POSIX threads on OpenBSD.
3405 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3406 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3408 When error is returned from present handler, non-surrogate diagnostic
3409 is returned in present response (and fetch handler is no longer called).
3411 * Minor adjustments to pquery parser (PQF). Token characters may be
3412 escaped by using backslash (C-style).
3414 PQF parser allows string attribute values to be specified. For @attr,
3415 non-numeric characters after the equal-sign are treated as strings
3416 (e.g. @attr 9=title).
3418 CCL trunction character may be defined (@truncation in file)
3420 * function zget_ExtendedServicesRequest sets waitAction to
3421 waitIfPossible (was wait).
3423 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3426 CCL operator names may be set in field definition files (CCL_bibset).
3427 See ccl/bib1 for an example.
3429 Fixes in ASN.1 compiler for C++ compatibility.
3431 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3432 and "op_or" to avoid conflict with C++.
3434 Fixed problem with GNU readline detection on Redhat 7.0.
3436 Added step-size for Scan backend handler.
3438 Fixed bug that made the frontend server crash when no attribute
3439 set was specified for scan.
3441 Front-end server automatically switches to original working directory
3442 when installed as an NT service. Previously -w had to be specified to
3445 Added extended attributes for retrieval module (data1), so that data1
3446 records carry d1_readXML/SGML attributes. d1_read also supports
3447 null-data rules ( <tag/>)
3449 On UNIX when POSIX threads are available, a separate library libyazthread
3450 is created. Programmers should link with that library and the yaz library
3451 when using threads. The reason for the split was that some applications
3452 on Linux, such as Apache, doesn't work well when using shared objects that
3455 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3456 (or any frontend server) in SSL mode by specifying ssl: followed by
3457 address. Only tested on UNIX.
3459 Added feature for CCL module. Virtual structure s=al or s=ol generates
3460 and-list and or-list respectively instead of phrase search.
3464 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3465 log_mask_str. This was done to avoid name conflicts with other libraries
3466 (such as other PHP extensions).
3468 Added raw OID member for preferred record syntax (request_format_raw)
3469 and returned record syntax (output_format_raw) for backend fetch method.
3471 Config file yaz-config now accepts options so that it returns specific
3472 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3474 Shared library support for UNIX using GNU libtool.
3476 * Modified backend interface. Request/Response struct's replaced by
3477 one read/write C struct. For example bend_fetchrequest and
3478 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3479 Every handler - even search has to be registered in bend_init
3480 handler. This means that the YAZ library no longer refers to
3481 external functions and it makes it possible to make the whole
3482 thing a single DLL/SO.
3484 Added Segment handler for backend server.
3486 Added Zmbol/Zebra administrative functions to YAZ client.
3488 Threaded frontend server on UNIX (when POSIX Threads are available).
3489 Starting the server with option -T enables multi-threading.
3493 Added configure option --enable-comp/disable-comp to control use
3494 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3495 located in sub directory asn.
3497 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3498 in ${exec_prefix}/bin along with the other programs yaz-client and
3501 GNU automake used to maintain makefiles.
3503 Added several OID's.
3505 Changed retrieval module so that we can load records with no abstract
3506 syntax defined. Tagpaths in these records are fully composed of string
3509 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3513 On UNIX, the generated makefile now supports a proper 'make install'.
3514 The prefix can be set via GNU configure to set the install location
3515 (default is /usr/local).
3517 * YAZ programs client and ztest were renamed to yaz-client and
3518 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3519 locations, such as /usr/bin,/usr/local/bin,etc.
3521 * YAZ Header files were moved from include to include/yaz. YAZ Header
3522 files are referred to as include <yaz/log.h> rather than <log.h>.
3523 The YAZ include path (-I ..) is therefore the same as before. Programmers
3524 should update their #include statements or use -Ipath/include/yaz
3525 instead. The main motivation for doing this change is that YAZ header files
3526 can be installed in "standard" locations /usr/include,/usr/local/include
3527 without introducing conflicts, since ALL YAZ header files are stored
3528 in subdirectory yaz (under /usr/include for example).
3530 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3531 rather than project/workspace files. We switched because project files
3532 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3535 Changed name of logging function, logf, to yaz_log, to prevent name
3536 clash with some math-log functions. The YAZ header log.h defines logf
3537 to yaz_log (#define) so there should be no incompatibilities by this
3540 Added bend_start/bend_stop handlers for server. These handler are
3541 called on start/stop of server. For windows they are called whenever
3542 a service is started/stopped.
3544 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3545 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3546 in util/yc.tcl. The auto-generated C code structures are, in a few
3547 cases, incompatible with the old decoders. There are differences in the
3548 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3549 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3550 The preprocessor variable ASN_COMPILED is defined when the compiled
3551 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3552 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3553 wish to use the old encoders/decoders you can specify --disable-yc
3556 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3557 version so that it supports both new - and old version of DB Update
3559 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3560 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3561 change. The name parameter can be set to 0 in which no name is specified
3562 for the construction. The macros odr_implicit and odr_explicit sets name
3563 parameter to zero for the construction involved. New macros
3564 odr_implicit_tag and odr_explicit_tag are similar to the others,
3565 except that a name parameter is added. For programmers' that don't use
3566 ODR they probably only need to change the call to z_APDU and z_External.
3568 Added access control facility by interfacing the TCP wrapper library.
3569 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3570 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3571 name of the daemon and enables the access control as specified in
3572 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3574 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3575 den Dool <H.M.vdnDool@kub.nl>.
3577 Added reference ID parameter to most functions in server API - refer
3578 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3580 Changed name of ccl library to libccl.a (was ccl.a).
3582 Fixed bug in decoder for Explain (Category TargetInfo).
3584 Added support for GNU readline in client. Thanks to Jacob Poulsen
3585 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3587 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3588 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3589 IMPLEMENTATION! This change was made to the development version before
3590 the ZIG decided to retract the amendment. If any users MUST be
3591 compatible with the original Update definition, PLEASE CONTACT US, and
3592 we will include a separate definition corresponding to the old Update
3593 ES. Note that because of the change to the ASN.1 of the
3594 TaskPackageRecordStructure we cannot define a single structure that
3595 will support both versions.
3597 * Added const modifier to buffer parameter for some ODR/BER encoding
3598 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3599 completeWAIS, odr_dumpBER.
3601 Fixed bug in client.c which caused a crash when a scanResponse didn't
3602 contain positionOfTerm.
3604 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3605 * will cause an error in a client if a non-YAZ target sends both a
3606 * list of Scan entries and non-surrogate diagnostics.
3608 Retrieval module enhancements. Tag sets may be typed in the reference
3609 to it. From the .abs-file the "tagset" directive takes a third optional
3610 integer type for the tag set referenced. From a .tag-file the "include"
3611 directive takes a third optional type as well. The old "type" directive
3612 in the tag set itself is still recognized but acts as the default type
3615 Backend interface change. Individual Scan terms returned from bend_scan
3616 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3617 in include/backend.h.
3619 Retrieval module enhancements. Multiple tag sets and attribute sets may
3620 be specified in abstract syntax specs. Revised the error/warning for
3621 logging messages reported by the retrieval module when reading the
3624 Object Identifier system (oid_..) changed. The API is backwards
3625 compatible but the oid-routines now allocates new OID's when needed.
3626 Raw OID's may be specified in oid_getvalbyname.
3628 YAZ now uses GNU configure to generate Makefile(s).
3630 * Minor changes in some of the member names of DeleteResultSetRequest and
3631 DeleteResultSetResponse. See include/proto.h.
3633 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3634 and added member 'languages' in TargetInfo (which was missing).
3636 Changed the way attribute sets are handled in the retrieval
3637 module. These are now cached, just like the abstract syntaxes
3640 Changed YAZ so that it links with compiled ASN.1.
3642 Added Explain-schema definitions and mapping routines. The following
3643 Explain categories have been implemented: AttributeDetails,
3644 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3646 Fixed minor bug in Windows version of Server Library.
3648 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3650 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3652 Added EXTERNAL: UNIverse Resource Report (non-standard).
3654 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3655 ENUMERATED and SET OF.
3657 * Added 'const' to some of the char pointer arguments for the
3658 functions, data1_read_node, data1_getelementbytagname,
3659 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3662 Fixed bug in data1_insert_taggeddata - the last_child member of
3663 parent wasn't initialised.
3665 * Changed data1_read_record and data1_read_node so that the supplied
3666 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3667 doesn't refer to any parts of the "SGML"-buffer.
3669 Fixed bug in server library (Windows version of statserv_remove).
3671 * Changed code so that it compiles as C++. The type definition
3672 of Odr_fun which is a member of Odr_arm was changed. The result is,
3673 that an explicit typecast is needed for the fun pointer when
3674 using Odr_arm - as in:
3675 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3677 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3679 Implemented the new structured date and time definition as approved
3680 by the ZIG. Added schemaId element to the specificTag in Espec-1
3681 (also approved at the last ZIG). Thanks to RVDM.
3683 Added some Object identifiers (RVDM).
3685 Changed the Update Extended Service (RVDM).
3687 Added command "refid" to client which specifies referenceId for
3688 the following requests.
3690 Implemented extended service handling for server. See ztest.c
3691 for an example as well as backend.h. New handlers are registerd
3692 in the Init handler.
3694 * Changed interface for sort in server.
3696 Added new members to statserv_options_block. It allows a server
3697 to read options from another source than just the command line. Thanks
3698 to Charles Woodfield.
3700 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3701 renamed to zboolean. Some C++ compilers complained about the name.
3703 Minor changes to gils.abs. Added index 's' (sort) on title
3704 and date/time-last-modified.
3706 --- 1.4pl2 1998/1/30
3708 Fixed bug in server library regarding inetd mode (-i). This bug
3709 was introduced by release 1.4.
3711 --- 1.4pl1 1998/1/29
3713 Added sort facility in client and backend server interface.
3715 Fixed problem with dependencies in Makefile(s).
3717 Fixed bugs for encoders/decoders of extended services and
3720 Implemented sub-tree feature for schemas. Sub-trees are
3721 referenced in *.abs-files. See explain.abs for an example
3722 of the use of this feature.
3724 Modified bib1.att; local attributes for ANY didn't include
3725 ANY itself (only affects use of the retrieval module).
3727 Fixed bug in plain SGML reader in function data1_read_node:
3728 tags with prefix "var" was incorrectly interpreted as variants.
3730 Added feature "sub-schemas" to enable references to - and definitions
3731 of - group of elements.
3733 * Removed member parent from type data1_element (in data1.h).
3735 Implemented function odr_nullval() that returns the value of
3738 * Removed member num_children from data1_node (in data1.h).
3740 Made NT service interface part of the server library. The
3741 function statserv_main uses the NT service when required and
3742 calls the statserv_start / statserv_close routines.
3744 Routine zget_SearchRequest and zget_PresentRequest fills
3745 resultSetName/Id member with "default" instead of "Default".
3747 Fixed memory leak in server. Request queue member wasn't freed.
3749 Fixed nmem_exit so that memory is freed.
3753 Revised the CCL parser utility to be thread safe.
3755 Added function, oid_ent_to_oid, to replace the function
3756 oid_getoidbyent, which is not thread safe.
3758 * Added nmem_init and nmem_exit to initialize and release
3759 NMEM resources. Function nmem_init should be called once in the
3760 initial thread before NMEM/ODR is used. statserv.c and client.c
3761 have been changed accordingly. The change was necessary to make
3762 NMEM thread safe. The NMEM memory pool is shared amongst threads
3763 in a process. Unix-based applications will still work fine without
3766 Added NT Services interface for the the Z39.50 (statserv) Server.
3767 Refer to the ztest.c source on the usage.
3769 Windows 95/NT port using MSVC5.0. Project files are included in the
3772 * Defined new 'global' handle for the retrieval (data1) system. The
3773 new handled, data1_handle, describes the state of the data1 system.
3774 This handle is passed as first argument to virtually all
3775 data1 related routines. The functions data1_create and data1_destroy
3776 creates and destroys a data1 handle respectively.
3778 Added ODR encode stream member to all backend request structures
3779 init, search, scan etc. This stream should be used to allocate all
3780 memory used for the response when thread safe operation is needed.
3782 Changed the comstack utility, cs_addstr, to be thread safe. The
3783 returned hostname string returned by the function is now part the
3786 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3787 function. The cs_straddr takes a COMSTACK handle as argument, so this
3788 function must be used after cs_create and before bind/connect.
3789 This function is thread safe.
3791 Moved test server to 'ztest' directory - generic server code still
3792 in 'server' directory.
3794 Made prefix query (pquery.c) utility thread safe.
3796 Added new function modifier YAZ_EXPORT to 'export' public DLL
3797 functions when using windows (see include/yconfig.h).
3799 Added definitions to the OID database (util/oid.c) (RVDM).
3801 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3803 Added call to ccl_rpn_delete in client program.
3805 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3806 release of RPN structure.
3808 Added support for C++, headers uses extern "C" for public definitions.
3809 With input from RVDM.
3811 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3812 Thanks to Ronald van der Meer (RVDM).
3814 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3816 Added support for private extensions to the OID database
3817 (oid_setprivateoids()). Thanks to RVDM.
3819 Added optional, physical ANY (key replication)
3821 Fixed null-reference problem in GRS-1 output filter.
3823 Proximity operator added to Prefix Query Format (PQF).
3825 In test client command "base" accepts multiple databases.
3827 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3831 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3833 Smallish bug-fixes in the new encoders/decoders (explain).
3835 Bug fixed in DeleteRequest.
3837 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3839 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3841 Added SOIF syntax (using private OID for now) to retrieval module and client.
3843 Added Update extended service.
3845 Added SearchResult-1 additional info structure.
3847 Added optional CCL (ISO8777) interpreter as separate module. Available
3850 --- 1.2 1996/6/10 (1st anniversary release)
3852 Added Summary record syntax. Lightly tested.
3854 Added OPAC record syntax. Untested.
3856 Added ResourceReport service encoders/decoders. Untested.
3858 Fixed bug in z_Unit - wrong tagging on unitSystem.
3860 Fixed bug in the DiagRecs decoder.
3862 Added options for max PDU size and session timeout to frontend-server.
3864 Added documentation of query-language parsers and other supporting utilities.
3866 [frontend-server] Added Attribute set to the bend_scanrequest API.
3868 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3869 surrogate diagnostics were generated.
3871 [retrieval] Allow multiple local values for attribute.
3873 [retrieval] Allow multiple attributes per element in .abs files. index type.
3875 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3877 --- 1.1pl2 1996/4/10
3879 Minor changes, mostly specific to Zebra's requirements (retrieval)
3883 Repaired bug in frontend server when running multiple listening
3884 endpoints in dynamic mode.
3886 z_External() now won't break if a known, ASN.1 value comes encapsulated
3887 in an octet-string. The value will pass through unmodified in an Odr_oct.
3889 Added a bit of code to the demo client to decode & display
3890 ASN.1-structured records represented in the octet-aligned branch of
3891 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3893 Added z_ext_getentbyref() to the ASN module. Doc updated.
3895 * Completed the SCAN definition in the ASN module. This may break SCAN
3896 code based on older YAZ-versions at compile-time. The fix is easy -
3899 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3900 under the SCAN definition. Remember to initialize this, server-people.
3902 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3903 that this does not extend to ODR and ASN.
3905 Comstack allows insertion of established socket (primarily for
3906 inetd-operation of servers). Doc updated.
3908 Front-end server can now start from the inetd in TCP mode. Doc
3911 --- 1.0pl4 1996/1/24
3915 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3916 the rank and record number.
3918 Adjustments to the frontend server.
3920 Fixed diagnostic BER dumper. It ignored the file argument.
3924 Various changes to retrieval module.
3926 Changed the union discriminators of the protocol files from enums to
3927 ints paired with #defines.
3929 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3932 *Changed operator in the RPN structure to 'roperator', again to avoid a
3935 Fixed problems in Explain decoders/encoders.
3937 --- 1.0pl2 1995/12/6
3939 Memory bug in log module fixed.
3941 --- 1.0pl1 1995/12/5
3943 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3945 Bug in Explain DatabaseInfo module fixed.
3947 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3951 The shift to v1.0 signals that we now consider the *core* functionality
3952 of YAZ reasonably stable (the core being more or less equivalent to
3953 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3954 tested (Explain not at all - though that will happen soonish).
3956 Minor changes to code to support Windows port.
3958 Various minor changes after we're getting to use GRS-1 & co. more.
3960 Added Espec-1 format.
3962 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3963 of the protocol and it cannot be selected when encoding (maps into 'string'
3964 when decoding). Needed to talk to some servers.
3966 Demo client can request simple element set names.
3968 Added Diagnostic Format encoders/decoders.
3970 Added simple Close handling to frontend server (no hooks for resource
3971 reporting yet), and demonstration client.
3973 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3975 --- 1.0b3 1995/08/24
3977 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3978 handled incorrectly when records were requested in the searchResponse. This
3979 will only affect you if you use the frontend-server.
3981 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3982 Test-client will ask for and print GRS1. Ztest will return dummy records
3985 Added Explain encoders/decoders to the service-level API. Untested.
3987 Added Extended Services: Item Order encoders and decoders to the Service-
3988 level API. Untested. We could use a recent copy of the pertinent bits
3989 of the ILL protocol to add those bits.
3991 Added diagnostic format 1 encoders/decoders to the service-level API.
3994 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3995 odr_cons.c, which causes a more correct output.
3997 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3998 was always set to 0 when no records were requested in the searchRequest.
4000 * Added better external-handling. This shouldn't harm old code that
4001 *encodes* externals. It can break code that looks for a
4002 'single-ASN1-type' representation, since those types that are known
4003 are now decoded immediately. Look at the SUTRS sample code in
4004 seshigh.c and client.c. Documentation updated.
4006 Handling of structured records in bend_fetchresponse. Length -1 marks
4007 structured record, type is deduced from format field.
4009 --- 1.0b2 1995/06/27
4010 Fairly quick maintenance release to add SUTRS support.
4012 Fixed handling of SUTRS records in the demonstration client.
4014 * Added format field to the bend_fetchrequest and bend_fetchresponce
4015 structures of the backend API (frontend server). When the record is
4016 returned, the value of the format field is mapped to an OID. The
4017 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4018 of the record. The special value VAL_NONE in the bend_request means
4019 that no specific format was requested by the client. Documentation
4020 updated accordingly. Test server (ztest) will return a fixed dummy
4021 SUTRS record if your client requests SUTRS.
4023 Documentation updated accordingly.
4025 You can now set external libraries and RANLIB support in the top-level
4029 First public release.
