3 daemon: properly report when receiving SIGUSR2 from child YAZ-785
7 xmalloc: throw assert for clearly invalid calls to malloc and
8 improve diagnostics YAZ-783 YAZ-784
12 Stop building debs for Ubuntu raring, quantal, oneiric.
14 CCL YAZ-781: for multiple use attributes in a specification the
15 generated RPN will perform @or on each term.
16 For spec: term u=31 u=1016
17 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
19 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
21 CCL YAZ-779: combo qualifier should allow for forward references
23 Fix buildconf.sh, automake too old on centos5 YAZ-778
24 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
25 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
26 accepts it without a warning.
30 GFS: client_query_charset conversion YAZ-777
31 This is a feature for Z39.50 clients that sends queries that are not
32 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
33 encoding given to UTF-8.
35 Echoed SRU arguments support YAZ-776
36 This is achieved with new function yaz_srw_get_pdu_e.
38 ZOOM: expire times set for redis/memcached YAZ-772
39 For both redis and memcached option --expire=seconds sets expire
40 time for a result-set/search. Default time is 600 seconds (10 minutes).
44 No [rest of output is omitted] limit for yaz_log YAZ-774
46 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
48 For ICU testing, pass -o to yaz-icu. This will test the
49 icu_iter_get_org_info function.
51 Fix null ptr reference for freeReplyObject YAZ-773
55 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
57 RPM: do not build with libmemcached support. The libmemcached library
58 on CentOS 5/6 does not work reliably for us (redis to the rescue).
60 configure: only allow libmemcached version 0.40 or later. That's the version
61 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
62 that's not an option, consider redis.
66 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
68 Fix zoom+memcached: present request out of range YAZ-767
72 CCL: add new qualifier r=omiteq which will omit relation=equals
73 for ordered relations. This should be used in combination with either
76 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
78 Solr: simplify yaz_solr_decode_response
80 Solr: use different local var for string manipulation
82 Solr: Get rid of hardcoded limit of extra_args
84 Solr: encode lucene query type YAZ-736
85 Make sure the queries are treated as traditional "lucene", because that's

92 Build packages for Ubuntu Trusty Tahr 14.04 LTS
94 wrbuf_cstr: fix off by one error.
96 wrbuf_buf: make it always return non-NULL
97 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
101 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
103 zoomsh: offer option -a apdulog
104 As we're used to from yaz-client and GFS based servers.
106 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
107 existing setting apdulog takes effect.
109 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
114 Add re-entrant CQL/Solr/RPN query conversion functions.
115 The re-entrant functions are: cql_transform_r,
116 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
117 These have same functionality as cql_transform,
118 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
119 return the additional infomration as WRBUF to make them re-entrant.
121 Remove CQL to Solr conversion and base solr_transform_t on
122 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
123 data structure as cql_transform_t.
125 cql2pqf utility allows RPN to Solr conversion
127 Fix assert in ZOOM when http connect fails YAZ-757
129 --- 5.0.22 2014/04/09
131 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
133 wrbuf_cstr: make it thread safe YAZ-753
135 yaz_log_init_file may take fd=<no> to open log file at the FD given.
137 --- 5.0.21 2014/03/21
139 Offer new utility function zget_AttributeList_use_string.
141 New conversion step, solrmarc, for record conversion module.
143 --- 5.0.20 2014/03/13
145 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
146 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
149 --- 5.0.19 2014/03/10
151 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
152 The standalone ZOOM sort was completely broken since 5.0.13.
154 ZOOM: generate event Connect rather than None for partial connect
155 (in fact getaddrinfo resolving).
157 ZOOM: only supply clientIP for InitRequest. Rather than for all
160 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
162 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
163 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
164 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
166 New "Facets" section in the documentation.
168 --- 5.0.18 2014/02/27
170 Call exsltRegisterAll in yaz_init_globals, so that all applications
171 using YAZ will have EXSLT things enabled.
173 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
175 Update various URLs to the re-organized SRU pages at LoC.
177 --- 5.0.17 2014/02/26
179 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
180 introduced in 5.0.12.
182 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
183 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
184 Do not call yaz_init_globals from log_mask_str_x. Problem introduce

193 Fix gcrypt not properly initialized YAZ-740.
195 --- 5.0.14 2014/02/19
197 Describe memcached option for ZOOM.
199 ZOOM: throw present request out of range again YAZ-739
200 Was removed in YAZ 5.0.13.
202 --- 5.0.13 2014/02/18
204 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
205 with localtime_r when threads + fork is used (such as Metaproxy).
207 yaz-config: quote some RHS values (that might include blanks)
209 zoomsh: shows SearchResult-1
211 zoomsh: sortby command
213 zoomsh: use proper list of connections and result sets YAZ-725
215 Avoid yaz_log in sigterm handler for GFS YAZ-737
216 Logging is still performed, but outside sig handler.
218 New ZOOM C feature: result-set caching with memcached. Example:
219 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
221 Remove SSL via OpenSSL support YAZ-732
222 Also deprecate two functions from comstack that aren't working with
223 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
225 Revert "Bison: use %name-prefix directive rather than -p option"
227 --- 5.0.12 2014/01/22
229 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
231 SRU GET/Solr base URLs may hold additional ?args YAZ-729
232 ZOOM option extraArgs already does this, though. It seems useful
233 when dealing with Solr targets to limit by filter, eg.
234 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
236 Remove #fragment for HTTP request encoding YAZ-730
238 Doc: Update list of DLLs/LIBs
240 Doc: update href link to Unix utils and Git.
242 --- 5.0.11 2014/01/15
244 ZOOM: fix "lost connection" problem with servers that uses both squid
245 and another proxy behind it that returns Location headers with relative
248 zoomsh: do not use readline for stdin (no tty) YAZ-724
249 Just use fgets in that case. If the user hits Ctrl-D a new-line
252 zoomsh: empty command ignored YAZ-723
253 rather than performing exit of zoomsh.
255 yaz-url utility offers option -v to enable verbose mode.
257 yaz_url uses yaz_check_location and offers verbose mode.
259 Add new function yaz_check_location.
260 This function gets an absolute URI from Location (HTTP redirect).
262 cookie API: introduce yaz_cookies_reset
264 Update cql.y for newer bison YAZ-720
265 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
266 longer supported. Instead one must use %lex-param and %parse-param .
268 --- 5.0.10 2014/01/09
270 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
273 rpn2solr: support truncation left(2), left&right(3) YAZ-718
275 Mention SRU version 2.0 in yaz-client man page.
279 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
284 Make cs_parse_host public.A
286 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
287 introduced in YAZ 5.0.6.
291 Fix buffer corruption for yaz-ztest record fetch.
295 Allow yaz-ztest to return user-defined records (one record per file).
296 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
298 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
299 Use the stream write instead of odr_printf which has a 4K tmp buffer.
301 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
305 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
306 can read and write this format. For record format JSON, yaz-ztest returns
307 MARC-in-JSON records.
309 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
310 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
314 Improve error reporting for ICU chains YAZ-707
315 Report config element+rule when ICU status is "failure".
317 ZOOM: stop fetching if present response has no records YAZ-710
318 Some targets return less records than their hit count would suggest.
319 This prevents ZOOM from continuing to fetch records if any present
320 response has 0 records in the response.
322 Ensure that GFS calls exit if any listener fails YAZ-710
323 Before, if XML config was in use, it would start the default
328 yaz-ztest: -V shows version (like yaz-client -V)
330 New iconv encoding: danmarc YAZ-692
332 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
334 daemon: only wait for immediate child rather than all children. YAZ-704
336 yaz-client: fix setting of SRU record schema. If scheme was unset, it
337 could lead to invalid memory reference.
341 yaz-ztest returns schema for MARCXML test records. SRU require that
342 recordSchema for records.
344 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
345 instead of non-surrogate diagnostic. This is a per-record failure.
347 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
348 may refer to multiple listeners now. Attribute listenref is a comma separated
351 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
352 option is given for GFS, the dirname of filename (for -f) is used
353 as prefix for options such as cql2rpn, ccl2rpn, etc.
355 Content-Type charset fixes YAZ-701 . Do not inspect charset in
356 Content-Type header for SOAP when decoding SRU. The payload (XML)
357 itself tells what encoding it is. In response, never supply encoding
358 in Content-Type. The response payload (XML) tells what it is (with no
359 encoding in XML it's UTF-8).
361 HTTP decoding: allow blanks in URL paths YAZ-700
365 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
366 and facets. Ensure recordData and recordSchema are always present in
367 record element, because they are required.
369 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
372 Simplify in a lot of places using odr_strdupn.
374 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
378 Increase various buffers in GFS's statserv_options_block
379 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
380 This change makes many type-casts redundant, and, thus simplifies code.
382 Remove last bits of WAIS support.
384 Remove member 'size' from Odr_oct.
386 Slim down the public part of 'struct odr'. Most elements are not part
387 of struct Odr_private.
389 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
390 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
391 In particular facets are supported in both client - and server side.
392 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
393 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
394 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
395 both request/response). This is what a search handler in the GFS
396 will see (regardless of whether operating in SRU mode or Z39.50).
398 Changes to the srw.h (SRU/Solr) definitions include:
399 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
400 (char*), which replace union query and query_type (int). This is because
401 SRU 2.0 supports a queryType parameter. This also means that, to carry
402 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
403 x-pquery=PQFstring (extention parameter). The extension parameter
405 - New element, packing, that has information about SRU
406 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
408 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
410 New element, packing, in Z_SRW_explainRequest.
412 New elements in Z_SRW_scanRequest, queryType and scanClause.
413 These replace query_type and scanClase untion. This is similar to what
416 --- 4.2.69 2013/10/01
418 GFS: log when closing down - at least SIGTERM YAZ-684
419 Also change formatting WRT PID logging a bit.
421 Improve display of MARC records with multi-byte subfield IDs YAZ-695
422 In some rare cases subfield identifiers are multi-byte characters.
423 This will try to deterime length of those and split accordingly.
424 This affects display in line mode as MARCXML/MarcXchange. The encoding
425 of ISO2709 is the same.
427 Change inp argument to const for yaz_read_UTF8_char.
429 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
431 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
433 Better check of marc leader info YAZ-691
434 Problem is that some systems generate MARCXML/MarcXchange with
435 funny headers. These will not work if encoded as ISO2709.
436 Some tests produce new output, due to updated warning messages
438 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
440 yaz-client: display MAB records YAZ-689.
441 Thanks for Heiko Jansen for this patch.
443 New utility z_get_HTTP_Response_server which allows both HTTP server name
444 and HTTP server URL to be given in response.
446 Debian: do not depend on obs tcl8.3.
448 Debian: do not depend on obs libicu36-dev.
450 --- 4.2.68 2013/09/23
452 GFS: pass additionalSearchInfo to search memeber search_input if
453 given. Otherwise pass otherInfo. Request for facets and other search
454 related things will be passed there in future versions of YAZ.
456 New ZOOM setting, authenticationMode, which allows authentication
457 paramters to be encoded in the URL rather than via HTTP Basic auth.
460 rpn2solr: fix nested AND/OR handling. YAZ-685
462 Add comparison routines for some Z-types, such as NamePlusRecord,
463 RPNQuery, Query, RecordComposition and OtherInformation.
465 --- 4.2.67 2013/09/19
467 Don't decode MAB as MARC. Just like we don't attempt to decode
468 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
470 CCL: allow quoted terms for date ranges. YAZ-681
472 Introduce ccl_parser_qual_search. This function makes old function
473 ccl_qual_search, from YAZ 2, available again.
475 Add yaz_facet_list_to_wrbuf. YAZ-683
477 --- 4.2.66 2013/09/11
479 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
480 schema was given for search. YAZ-675
482 Add Solr date range searches. YAZ-621
484 --- 4.2.65 2013/08/22
486 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
488 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
490 ISO2709/MARC parse most octet aligned records; not just those that
491 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
492 MARC parse more records instead of just dumping as is. YAZ-670
494 ZOOM: proper caching for variations of record schema. YAZ-671
496 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
498 --- 4.2.63 2013/07/17
502 --- 4.2.62 2013/07/11
504 New utility z_get_HTTP_Response_details - an extended version of
507 New utility yaz_url_get_error which returns error message of last
508 failed yaz_url_exec call.
510 yaz-url and url functions: allow max HTTP redirects to be controlled.
512 New functions yaz_file_glob2, yaz_xml_include_glob.
513 These functions takes a flags parameter, which, for now only controls
514 whether to fail inclusion of a non-existing file (without glob
515 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
517 --- 4.2.61 2013/06/20
519 For MARC XML parsing, allow record without leader. A fake/default leader
520 is inserted and a warning is tagged with the record.
522 ICU: fix leak in in icu_iter_get_org_info.
524 --- 4.2.60 2013/06/14
526 ICU: fix bug in icu_iter_get_org_info (un-init variable).
528 --- 4.2.59 2013/06/11
530 Implement z_HTTP_header_remove.
532 --- 4.2.58 2013/06/11
534 ICU: Disallow 0 ptrs for some ICU string utilities.
536 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
537 returns original tokens (before normalization).
539 CCL: avoid z39.58/regex truncation when not needed. Apply only the
540 conversion of those masks, when absolutely necessary.
542 CCL: configurable masking character - @mask. Default masking character
545 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
546 full response anyway, so a Transfer-Encoding header will obstruct the
549 --- 4.2.57 2013/05/15
551 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
552 picking a socket. Problem is that some systems has IPV6 support, but
553 we can't create sockets for them, so we pick AF_UNSPEC first.
555 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
556 use content_len to determine resulting Content-Length in HTTP response
557 and NOT Content-Length supplied in headers by user.
559 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
560 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
562 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
565 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
566 with big endian and unsigned char (by default).
568 --- 4.2.56 2013/04/26
570 Fix yaz-client connect (crash in 4.2.55).
572 --- 4.2.55 2013/04/26
574 Fix proxy/host problem for ZOOM that could occur if unix sockets
577 New Debian package libyaz4-dbg.
579 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
580 differently in tcpip_close.
582 --- 4.2.54 2013/04/17
584 Windows installer of YAZ includes YAZ4J as a component.
586 CQL: allow "extra terms" again, by default. Thus, the CQL parser
587 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
588 and earlier. CQL parser may operate in strict mode where queries
589 not conforming to the standard BNF are rejected (syntax error).
590 Whether the CQL parser operates in strict mode is controlled with
591 cql_parser_strict . Strict mode enabled with option -S for utilities
592 cql2pqf and cql2xcql .
594 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
596 --- 4.2.53 2013/04/10
598 New charset, MARC-8c, which is like MARC-8 but allows control characters
599 0x01 through 0x1F, except ESC to be passed through verbatim.
601 Fix a problem with duplicate sub field character in MARC output. Problem
602 happened only when output was MARC-8 encoded.
604 --- 4.2.52 2013/04/03
606 yaz-ztest: Use hash for fake hit count. Before, random number was used.
607 This is problematic for unit tests using yaz-ztest. This patch also makes
608 a hash for CQL queries. For RPN, any term with a leading digit will be
609 treated as pseudu hit count (to force any particular hit count by a client).
611 yaz-ztest: return unique MARC dummy records. Beyond record offset
612 24, the author surname is patched with offset to make all records
615 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
616 on system wide default (/proc/sys/net/ipv6/bindv6only).
617 @4 binds to IPV4 only. @6 binds to IPV6 only.
619 Update CQL API documentation a bit
621 CQL: don't accept extra terms for queries. Makes the CQL parser
622 stricly conformant to the standard.
624 --- 4.2.51 2013/02/12
626 GFS: scan handler gets extra_args from request and may return extra
627 response data . That's for SRU only.
629 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
631 --- 4.2.50 2013/01/30
633 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
635 OPACXML: sync spelling of availabilityDate in XML to that of Schema
636 opaxxml.xsd. The schema had the correct spelling of this member always.
637 The ASN.1 was mis-spelled and still is (API change) - we are
638 not changing this. However, the OPAC to XML conversion had yet
641 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
644 New function, z_ext_record_oid_nmem, which is similar to
645 z_ext_record_oid but takes NMEM rather than ODR
647 --- 4.2.49 2013/01/18
649 ICU: New conversion element 'join' which joins tokens into one
650 with a custom character given by rule attribute.
652 --- 4.2.48 2013/01/10
654 New GFS search member: present_number. This is a hint to the
655 search handler how many records are going to be fetched immediately
656 following search. There's no guarantee that it's going to be the case,
657 since it depends on hit count (for Z39.50 piggyback) and whether errors
660 Make a few functions static (private). The functions getbyte_stream,
661 ungetbyte_stream and yaz_gets are now private. They were never declared
664 yaz-marcdump: exit(5) for serious decoding errors
666 ISO2709 decoding: be more picky WRT header
668 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
669 was only used as to indicate that next-result-set-position should be
671 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
672 Based on patch from Ashley Sanders.
674 Make some functions static/private in PQF parsing. Those functions were
675 never declared in a public header and so should not be in use by
676 applications based on YAZ.
678 --- 4.2.47 2012/11/23
680 ZOOM: special options to control APDU logging.
681 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
682 logging of APDUs until "saveAPDU" option is set again. If logging is
683 already enabled the effect is that current APDU buffer is cleared.
684 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
685 logging (default behavior on new connection).
686 The APDUs sent/received can be obtained by using
687 Using ZOOM_connection_option_get(c, "APDU") or
688 ZOOM_connection_option_getl(c, "APDU", &l).
690 GFS: relay implementation_version from backend
691 From 3.0.40 and later, implementation_version from backend was
692 not used in init response at all.
694 --- 4.2.46 2012/11/15
696 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
697 mode at all. Probably never did.
699 Make a new version of ztest.pem that, at least, is not expired.
701 --- 4.2.45 2012/11/13
703 Fix description of CCL directive 'case'.
705 More tight checking of form arguments (yaz_uri_to_array). Makes
706 YAZ better at rejecting big and/or bad POSTs.
708 SRU decoding does not report more than up to 10 invalid arguments.
710 rpn2cql: less quotes in generated terms. Semantics unchanged, but
711 it's prettier this way.
713 --- 4.2.44 2012/10/25
715 New utility yaz_decode_init_diag. Defined in proto.h.
717 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
718 given for unix local socket.
719 The COMSTACK string for doing so is:
722 unix:/myfile:tcp:localhost:9999/mybase
723 unix:/myfile:localhost:9999/mybase
724 unix:/myfile:http://fakehost/mybase
726 debian: Use dpkg-buildflags in build process.
728 --- 4.2.43 2012/10/19
730 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
731 global's SRU service uses a recordPosition scheme starting from zero.
732 First record's position should be one
733 according to the standard.
735 --- 4.2.42 2012/10/18
737 Allow more namespaces for SRU. This is to allow, for example, an
738 incorrect namespace returned from server
739 http://services.igi-global.com/sru .
741 Minor fixes for compilation on Windows.
743 --- 4.2.41 2012/10/11
745 daemon: log total number of bad signals from child on stop so that it
746 is more easy to spot problems with child worker processes.
748 retrieval: empty backend name attribute omits element set
749 from being used in retrieval.
751 --- 4.2.40 2012/10/04
753 Implement Solr sort strategy "solr", similar to sru11 sorting.
754 This will implement the correct parameters on Solr requst to do
757 --- 4.2.39 2012/09/28
759 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
762 MARC: Extra/missing indicator handled for MARCXML.
763 The indicator length is given in header and is the same for the
764 whole record. If attributes ind1, ind2 are missing, then content
765 character defaults to blank. Extra indicator attributes (beyond)
766 indicator length are treated as an error.
768 Reformat: delete trailing whitespace
770 --- 4.2.38 2012/09/17
772 MARC: fix non-ASCII characters for leader. This is to ensure we can
773 generate XML in UTF-8.
775 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
776 in one node with structure word.
778 --- 4.2.37 2012/09/04
780 yaz-json-parse: JSON output may be pretty printed by using option
783 Increase default value of max message for Z39.50 Init for GFS, ZOOM
784 and yaz-client. Old value was 1 MB. New value is 64 MB.
786 --- 4.2.36 2012/08/22
788 yaz-client: don't display bogus records from SRU servers. Some SRU servers
789 return more records than given by *maximumRecords*. Skipping those in
792 record_render: simplify buffer return handling and fix at least one bad
793 memory reference, that broke the test_embed_record sometimes.
795 Allow http://user:pass@host notation for yaz_url_exec.
797 zoomsh: allow shell command to be executed. Via the system(3) call.
799 yaz_poll: Allow num_fds == 0
801 yaz-client: fix bad encoding of "itemorder item". The itemorder
802 item <no> - command forgot to use length of encoded Item Request
803 package. Error present since YAZ 3.
805 yaz-ztest: fix bad usage of session handle. Bug was introduced when
806 result sets were saved (271a9c83).
808 SRU recordPacking: guess record packing in response rather than looking
809 at the recordPacking element which, OF COURSE, changed semantics in SRU
812 Decode SRU 2.0 responses. The official namespace for responses, according
813 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
814 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
815 nature.com's server, however, usee namespace
816 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
817 we are now using a glob-expr to match up the namespace. ZOOM C and
818 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
819 I can not find a single real example showing the "real" namespace in
820 the documentation from OASIS. The namespace for requests is different
821 from responses, but this is not added to YAZ yet, when we don't encode
824 --- 4.2.35 2012/06/26
826 zoom/record_render: add support for Base64 decoding fo MARC records
827 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
828 which will decode base64 + ISO2709 marc-8 encoded material from text node
831 --- 4.2.34 2012/06/07
833 Add missing definitions ZOOM_resultset_get_facet_field_by_index
834 and ZOOM_resultset_facets_names.
836 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
839 Change APDU dump printing to avoid long leading blanks. For levels 16
840 or larger the level is shown and the indentation is truncated but
841 recursed with modula 8. This makes it still reasonable easy to read
842 - even for nested BER dumps.
844 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
845 return 0 (incomplete package) in case where the BER package was
846 considered too nested (return value of -2).
848 dumpber: lines of level 15 are not indented further. Two spaces per
849 indentation; indentation 15 or more is indented to a fixed indentation
850 and augmented with a level=<no> indication.
852 zoomsh: increase max size of command+args
854 GFS: No limit in RPN buf size in CQL to RPN conversion.
856 --- 4.2.33 2012/05/09
858 New function for daemon utility, yaz_daemon_stop .
860 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
862 --- 4.2.32 2012/04/25
864 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
865 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
867 --- 4.2.31 2012/04/23
869 YAZ daemon utility relays SIGUSR1 to child process.
871 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
872 would result in en empty database list - which in turn would result in
873 encoding failure for search.
875 Fix reading beyond string in yaz_sort_spec.
877 --- 4.2.30 2012/04/11
879 Add two new SRU diagnostics:
880 236: Access to specified database denied
881 1015: Init/AC: Maximum number of simultaneous sessions for Userid
883 Document the very useful ZOOM-C option "apdulog".
885 CQL to RPN: term may be passed through verbatim. This is enabled with
886 truncation.cql . The assumption being that the term is already CQL.
888 --- 4.2.29 2012/03/20
890 record_conv: leader spec may be given for marc element.
891 The leader spec is given as attribute leaderspec for element marc.
892 For example to convert a MARC21 record from MARC-8 to UTF-8:
893 <marc inputformat="marc" outputformat="marc"
894 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
896 record_conv: allow user-XSLT params. For example:
897 <xslt stylesheet="MARC21slim2DC.xsl">
898 <param name="myparameter" value="myvalue"/>
899 <param name="otherparameter" value="othervalue"/>
902 record_conv: fix error handling for missing marc charsets.
904 CQL: fix extra terms in wrong order.
906 --- 4.2.28 2012/03/06
908 record_conv: modify new API for conversion types. The conversion types
909 may be passed in new functions yaz_record_conv_configure_t and
910 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
912 Avoid mixed statement/variable declare; fixes compilation with Visual
915 --- 4.2.27 2012/02/28
917 Add non-standard SRU diagnostic: 235: "Database does not exist".
918 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
919 Update SRU to Bib-1 diagnostic maps accordingly.
921 CCL: add two new diagnostics for unsupported masking. The new
922 diagnostics are: "Embedded truncation not supported" and
923 "Single charcacter mask not supported".
925 --- 4.2.26 2012/02/23
927 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
929 --- 4.2.25 2012/01/11
931 Build YAZ for Ubuntu Oneiric.
933 CCL: allow parantheses for proximity operands. For example CCL query
934 (a) % (b) is now allowed.
936 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
937 marked dead, rather then being destroyed. If not, the session memory is
938 being free'd before the search/scan handler is finished. Also destroy
939 'request' memory in request_release rather than in various places,
940 which resulted in leaks from time to time.
942 --- 4.2.24 2011/12/21
944 cql_sortby_to_sortkeys: honor sort prefix.
946 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
947 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
948 The rpn2cql family of functions now always returns quoted CQL terms.
950 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
952 --- 4.2.23 2011/12/15
954 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
955 sequence is treated as one. For example, &&a=b&&&c& is identical to
958 --- 4.2.22 2011/12/05
960 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
961 APDUs for a connection to a WRBUF.
963 --- 4.2.21 2011/11/23
965 Fix cql_sortby_to_sortkeys. Completely broken before.
967 Make CCL's @truncation work again.
969 --- 4.2.20 2011/11/09
971 New ZOOM connection setting: tproxy. It's like proxy, but does not
972 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
973 to set resolved address + port for a connection outside ZOOM itself.
975 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
977 --- 4.2.19 2011/11/07
979 Fix uninitialized variable in Solr spell support (could cause SEGV
980 for SRU response decoding).
982 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
983 back-end's addinfo through into the ZOOM response addinfo.
985 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
986 they are separated by a colon and a space rather than simply
989 --- 4.2.18 2011/10/28
991 Add support for Solr spell-checking/suggestions through ZOOM.
992 If a Solr target has been configured correctly for spelling-checking
993 and suggestions, these will now be returned on the ResultSet option
994 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
996 --- 4.2.17 2011/09/28
998 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
999 with a flag whether to substitute escape sequences or not.
1001 --- 4.2.16 2011/09/22
1003 Fix nmem_strsplit_escape to substitute escape char properly.
1005 New option for zoomsh -e , which makes it abort on first error and
1006 return process exit code to indicate success/failure.
1008 YAZ options utility supports special option -- which makes all it treat
1009 all following arguments as non-options.
1011 --- 4.2.15 2011/09/16
1013 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1014 searched if absolute filename is given.
1016 Fix conv_xslt() error-reporting when stylesheet is not found.
1017 (The value of fullpath is meaningless in this situation.)
1019 --- 4.2.14 2011/09/07
1021 Fix problem in CQL sort node creation: un-initialized memory.
1023 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1024 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1025 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1028 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1029 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1031 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1032 will make it possible to use both single-character mask (#) and wildcard (?)
1033 in CCL . Throw diagnostic for left truncation because that is not supported
1036 --- 4.2.13 2011/09/01
1038 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1039 cases using escapes (\-sequences) and masking.
1041 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1042 would result in a read one byte beyond string.
1044 rpn2ccl may use Z39.50 masking for terms (t=z).
1046 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1048 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1049 not --cppflags (which seeems like an error in icu-config).
1051 --- 4.2.12 2011/08/27 RPM package only
1053 cql2ccl: fix conversion of terms: operator characters were not
1056 --- 4.2.11 2011/08/25 RPM package only
1058 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1059 CCL parser will map both # and ? to their regular expression
1060 quivalents (. and .*).
1062 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1063 of reserved CQL characters.
1065 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1066 is, so that they are passed through.
1068 --- 4.2.10 2011/08/24
1070 ZOOM SRU mode: more aggressive re-connect.
1072 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1073 made available as a utility function, declared in <yaz/logrpn.h>
1075 rpn2cql_structure() supports proximity nodes (except that the Type-1
1076 proximity node's "exclusion" binary is ignored, as there is no way to
1077 express that in CQL). Fixes bug #4564.
1079 --- 4.2.9 2011/08/18
1081 Fix SEGV that could occur if set command of zoomsh was given without
1082 value (2nd argument).
1084 Fix SEGV that could occur if unsupported transport was given for
1085 COMSTACK - say https (when SSL was unavailable).
1087 Build yaz-url on Windows too.
1089 --- 4.2.8 2011/08/11
1091 New utility to get web content. Header is url.h. A command line tool
1092 yaz-url is part of the distribution and packages.
1094 Fixes for SSL COMSTACK (when gnutls is in use).
1096 New functions yaz_base64{encode,decode}. Header is base64.h.
1098 --- 4.2.7 2011/08/03
1100 ZOOM C includes HTTP response buffer as additional info if it fails
1101 to decode the SRU response.
1103 Make wrbuf_json_puts available.
1105 --- 4.2.6 2011/07/28
1107 zoom: throw diagnostic for invalid value for option "sru". Before a
1108 bad SRU request was sent.
1110 Adding new utility wrbuf_vp_puts.
1112 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1114 --- 4.2.5 2011/07/21
1116 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1117 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1118 redirect was used at the same time.
1120 MARC line mode decoding: be less picky about length given - first
1121 5 digits of header that is.
1123 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1125 Changes to decoding of SRU records: a record with recordPacking=xml is
1126 modified with a new root element <yaz_record> if the recordData contains
1127 multiple children elements. This is to make the record XML parseable
1130 RPN to Solr conversion: encode special characters.
1132 Generic Frontend Server: fix uinitialized member, stepSize.
1134 --- 4.2.4 2011/06/21
1136 Fix a bug in SRU decoding of records.. The database records stored
1137 had un-initialized memory, but it would only be seen with yaz_record_render
1138 and type_spec="ext" .
1140 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1142 --- 4.2.3 2011/06/17
1144 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1146 --- 4.2.2 2011/06/10
1148 Add new utilities to convert from CQL to CCL . These utilities have
1149 prefix cql_to_ccl defined in cql.h.
1151 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1152 lead to memory heap corruptions when ICU utilities were in use.
1154 --- 4.2.1 2011/06/07
1156 Make compilation work without Libxml2.
1158 yaz-client: remove redundant blanks in display of searchResult-1 term
1161 --- 4.2.0 2011/05/18
1163 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1164 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1166 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1167 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1168 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1169 Note that the CQL sortby spec is only converted when the GFS is already
1170 converting from CQL to RPN (cql2rpn element).
1172 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1173 specify whether to collapse delimitors or not. The existing nmem_strsplit
1174 do collapse (collapse parameter = 1).
1176 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1178 Rename internal func yaz_use_attribute_create. While non-static, this
1179 function is not declared in a public header.
1181 --- 4.1.7 2011/03/15
1183 Add -lCrun when linking with ICU on Solaris.
1185 More quicks character set conversions for OPAC records.
1187 --- 4.1.6 2011/03/10
1189 fix problem with record_render: records were converted (character set
1190 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1192 --- 4.1.5 2011/03/08
1194 SRU: add methods for handling DADS SRU-proxy facets.
1196 Separate OPAC record character set for ZOOM_record. yaz_record_render
1197 allows a character set given as charset=from/opacfrom,to where 'from' is
1198 the character set of a bibliographic record, 'opacfrom' is character set
1199 of OPAC record and 'to' is the target character set.
1201 --- 4.1.4 2011/02/21
1203 yaz-client: show may XML format records. Command show followed by 'format'
1204 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1207 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1210 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1212 --- 4.1.3 2011/01/27
1213 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1215 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1216 this package can be distinguished from other vendors.
1218 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1219 as determined by configure
1221 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1223 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1224 returns no error and no record, the present request is considered
1225 partial (only a subset of the records could be returned by backend), and
1226 so it is appropriate to set Present Status to partial-4.
1228 --- 4.1.2 2010/11/02
1230 Move yaz-config man pages to section 1.
1232 More documentation about Solr.
1234 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1235 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1236 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1237 peers on some Linux systems. However, in general that does not work
1238 so YAZ can not rely on that to work. Debian changed behavior in this
1239 respect from Debian lenny to Debian squeeze (still testing as of Oct
1241 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1243 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1245 --- 4.1.1 2010/10/05
1247 Fix yaz-config output: echo_source not set correctly by configure.
1249 --- 4.1.0 2010/10/05
1251 Solr Web Service support for yaz-client and ZOOM.
1253 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1255 --- 4.0.12 2010/08/17
1257 Z39.50 facet support. Facet specifications are passed for search in
1258 other-information with ASN.1 as defined in facet.asn and OID
1259 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1260 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1261 3 is limit (number of entries to get in response). yaz-ztest returns
1262 dummy facets if a client asks for them.
1264 --- 4.0.11 2010/07/09
1266 CCL fixes: bug 2895 and bug 3539.
1268 GR1-display: add comma in display - was removed by mistake in
1271 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1273 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1275 --- 4.0.10 2010/06/18
1277 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1278 result set from a connection. The result set will be on its own
1279 thereafter; no operations on it will perform retrievals from a target.
1280 Only cached copies are returned.
1282 ZOOM C:fix case for HTTP servers responding with Connection:close.
1283 Ensure that if there is a current task it is resumed (like fetching
1284 more records in a result set) . Bug #3484.
1286 PQF parser: use odr_atoi for Odr_int (not atoi)
1288 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1289 values that contain any non-digits are treated as string attributes
1290 (previously decoding only checked for leading character ([0-9]). PQF
1291 encoding: attribute string values are not surrounded by double-quotes.
1293 --- 4.0.9 2010/05/21
1295 New utility for managing threads - thread_create.h.
1297 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1298 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1299 but YAZ' implementation do.
1301 Fixes for yaz_cond-functions on Windows 7.
1303 DLL export more symbols.
1305 zoomsh: show record do NOT render opac.
1307 Remove *.la files from Debian and RPM packages.
1309 --- 4.0.8 2010/05/11
1311 Debian package libyaz-dev depends on libgnutls-dev again (was
1312 removed in YAZ 4.0.6, but due to Libtool it is still needed
1313 even though yaz-config do not list libgnutls libs).
1315 ZOOM: Use only one WRBUF for returning string results for
1316 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1318 ZOOM: ZOOM_connection do not use a shared pointer to
1319 ZOOM_resultset after ZOOM_resultset is destructed by
1320 user. Reverts to YAZ 4.0.4 behavior.
1322 --- 4.0.7 2010/05/04
1324 record-conv: fix problem with at least one XSL conversion -
1325 due to probably incorrect usage of XML XSL documents.
1327 --- 4.0.6 2010/04/29
1329 Fix yaz-config for static mode and the use of SSL (gnutls).
1331 --- 4.0.5 2010/04/29
1333 Forward decl timeval struct in mutex.h and gettimeofday.h.
1335 yaz-config: fix 'static' mode linking.
1337 --- 4.0.4 2010/04/28
1339 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1340 are wrappers for pthreads or Windows. For Windows these are put in
1341 a separate DLL: yaz_cond4.
1343 libyaz.la (whole source) is compiled with thread. If thread support
1344 is enabled enabled, all source of YAZ is compiled with treading support.
1345 This allows core utilities such as yaz_log to use thread facilities.
1346 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1347 thread utilities. This commit moves mutex utilities (mutex.c) from
1348 libyaz_server.la to libyaz.la.
1350 yaz-json-parse displays leading text until error.
1352 --- 4.0.3 2010/04/09
1354 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1355 patch from Giannis Kosmas.
1357 SRU: no longer URL encode SRU database. The URL for an SRU server is
1358 a URL and such is alreeady encoded - at least when given with leading
1359 http:// or https://. This reverts behavior to YAZ 3.0.50.
1361 Support for new MARC XML notation TurboMARC which like MARCXML is a
1362 complete representation of MARC/ISO2709.. This one, however, is more
1363 compact and allows for faster processing with XSLT. TurboMARC can be
1364 used in the marcdisp.h API, from the yaz-marcdump utility and from
1367 yaz-ztest can be configured - via the database - to perform certain
1368 delays when it performs operations search, present and single record
1369 fetch. This allows testers to make yaz-ztest act as a real or even slow
1370 Z39.50 server. Refer to the yaz-ztest man pages for details.
1372 --- 4.0.2 2010/03/09
1374 wrbuf_destroy allows NULL WRBUF passed to it.
1376 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1378 Add ZOOM_connection_close.
1380 No fixed size buffers for ZOOM shell - bug #3257.
1382 tstodr: make it work on s390 platform.
1384 New icu iterator-functions. The new icu_iter-functions makes it possible
1385 to use ICU chains from many threads.
1387 yaz-client: better syntax check for show command.
1389 --- 4.0.1 2010/01/26
1391 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1394 New simple local-file XML include facility which allows file glob-patterns.
1395 Refer to yaz/xml_include.h.
1397 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1400 ZOOM_record_get supports new parameter "format" which makes it format XML
1403 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1404 JSONText in ECMA-262) is JSONValue, not JSONObject.
1406 --- 4.0.0 2010/01/20
1408 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1409 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1411 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1412 POSIX/Unix builds .so with major version 4.
1414 Remove old LOG_-defines from log.h. They have been obsolete and
1415 undefined by default for the last 5 years.
1417 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1419 GFS: Remove socket (int *fd) from search_rr handler. The socket
1420 descriptor ptr is a facility that allowed a search handler to supply
1421 a socket which would serve as a callback - when search was complete.
1422 This facility has now been in use for years.
1424 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1425 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1426 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1427 returns 'const char *' rather than 'char *. The returned string is
1428 read-only and should not be modified by applications. COMSTACK cs_close is
1429 now a void function - it no longer returns int. No applications check for
1430 the value and the implementations has always returned 0.
1432 ZOOM: use size_t for scan hit counts and str size. Functions
1433 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1434 occ (hit count) and len (string length) are now of type size_t pointer
1435 rather than int pointer. This is to be able to represent large hit counts
1436 and to also just to use the proper type for string length (strlen result).
1438 New JSON parser. Refer to include/yaz/json.h .
1440 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1441 Used to be int in some cases. Many wrbuf_-functions used to return an int
1442 indicating some length.. These return values were never used. And so they
1445 ODR: odr_malloc, odr_total now takes size_t for size.
1447 clone_z_type: fix leak; occurred for encoding failures.
1449 --- 3.0.52 2009/12/03
1451 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1452 bug was introduced in 3.0.51.
1454 --- 3.0.51 2009/12/02
1456 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1458 tcpip comstack: fix leak for getaddrinfo.
1460 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1461 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1462 Decoding of SRU "path" database is performed by private function
1463 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1464 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1466 yaz-client: honor base command for SRU. Change when database setting
1467 is applied for SRU and ensure it is kept when a connection is reset.
1468 Change also the way errors are displayed or SRU (decoding of packages).
1470 --- 3.0.50 2009/11/02
1472 Add support for extra request / response data for SRU codecs and GFS.
1473 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1474 for extra data response buffer and length. For the GFS, both request
1475 and response data (XML) is carried in extra_args and extra_response_data
1476 for the search handler. Patch by Ko van der Sloot.
1478 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1479 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1480 10010). This fixes bug #2113.
1482 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1483 cmdfile included a 'quit' command that would result in a memory violation.
1485 --- 3.0.49 2009/10/01
1487 Make a number of functions defined in xmlquery.c static. These have
1488 never been declared in a public header file (yaz/xmlquery.h) and was
1489 made public by mistake.
1491 Improve speed of character conversions (iconv utilities). This makes
1492 conversions from MARC-8 faster.
1494 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1495 unless type desired is "raw". This will prevent type "xml" from
1496 returning ISO2709 .. Which obviously can not be XML parsed.
1498 Fix memory leak in ZOOM that would occur if option apdulog was used
1499 on a re-used connection.
1501 Frontend server logs HTTP requests.
1503 Frontend server now sends Z39.50 close when it times out (sesssion has
1504 been idle for too long). Versions 2.0.30 and earlier also sent close.
1505 But due to a mistake this was disabled in all versions after that, i.e.
1506 the server would just close the socket immediately.
1508 yaz-client emits a better message when receiving an unrecognised
1509 userInformationField.
1511 Skip zero-length subfields when decoding ISO2709. This rare case happens
1512 if a record has two FS characters in a sequence. Without this patch
1513 there would be a reference beyond char array in using_code_len fragments
1516 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1518 --- 3.0.48 2009/08/28
1520 The show command offered by the zoomsh command now takes a 3d optional
1521 parameter type which is what is passed to ZOOM_record. If the type
1522 argument is omitted, "render" is used.
1524 RPN to CQL conv may use USE string attributes (bug #2978).
1526 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1528 --- 3.0.47 2009/07/08
1530 Function yaz_xml2query allows a diagnostic element in the PQF XML
1531 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1532 code and additional info respectively.
1534 The BER BOOLEAN is now the integral type Odr_bool which still happens
1535 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1536 typedef'd to Odr_int. This is still an integral 'int', but it may be
1537 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1538 ASN-1 compiler as well as programs has been updated to use the new types.
1540 --- 3.0.46 2009/06/08
1542 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1543 only the bibliographic record was rendered. For type=opac, an OPAC
1544 record is only returned if it is present.
1546 iconv: small fix for encoding of advancegreek.
1548 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1550 yaz-client: option auto_reconnect=on really reconnects.
1552 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1554 server: avoid null ptr ref for for yaz_poll errors.
1556 build: fix RPM build for RHEL 5.3.
1558 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1560 --- 3.0.45 2009/03/31
1562 Fixed bug #2709: TCP connect returns Invalid argument.
1564 Fixed compilation for mingw.
1566 Honor charset for raw records (ZOOM_record_get).
1568 Fixed use of errno for threaded mode that was seen on Solaris 10.
1570 Fixed argument passing with blanks in value for Windows Service.
1572 Disable YAZ' own log rotate by default (no 1 GB limit).
1573 The variable l_max_size which specifies the log file limit is set to 0
1574 (DISABLED): This is due to the fact that YAZ is most often deployed using
1575 logrotate. Also YAZ can not perform log rotate because of unsufficient
1576 permissions (setuid).
1578 --- 3.0.44 2009/02/17
1580 List supported encodings in man page for yaz-iconv.
1582 Fixed missing SSL libs for --libs output
1584 Re-established OID record syntax application-xml. Nobody should use it
1585 but we don't want to change soname because of this symbol being absent.
1587 --- 3.0.42 2009/02/02
1589 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1591 Added member named_result_sets for init handler struct for the GFS. This
1592 allows a server to disable named result sets.
1594 Removed OID record syntax application-xml.
1596 Added support for rule-based transliterator for ICU wrapper of YAZ.
1598 Fixed bug #1902: yaz-icu XML output.
1600 Make YAZ checks Emacs friendly.
1602 BITSTRING value shows value. Bug #2346.
1604 ISO2709 decoding: skip control characters from indicator data.
1606 Omit sort key by default in yaz-icu's output.
1608 Allow combined single char options (again) for YAZ' options function.
1610 Utility yaz-marcdump got option to display YAZ version (-V).
1612 Allow YAZ to use ICU 3.4.
1614 Added new ICU test case which illustrates removal of diacritics.
1616 --- 3.0.41 2008/12/29
1618 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1620 --- 3.0.40 2008/12/29
1622 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1625 Fixed bug #2352: yaz-marcdump crashes for certain record.
1627 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1629 Added support for Danmarc2 to UTF-8 conversion.
1631 Added support for ISO5426 to UTF-8 conversion.
1633 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1634 implementation version.
1636 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1638 --- 3.0.38 2008/11/10
1640 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1641 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1643 ZOOM C now interprets databaseName option for ZOOM connection as path
1646 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1648 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1650 Dummy Libxml2 types no longer defined in headers of YAZ'.
1652 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1655 --- 3.0.36 2008/09/26
1657 Various ODR chapter fixes.
1659 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1661 Added missing source for Windows compilation, mutex.c.
1663 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1665 For SRU connections in ZOOM all records up to "count" are now fetched.
1667 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1668 in Windows due to bad error handling for Libxml2.
1670 Added facility for sending arbitrary records (ASN.1 any) using
1671 ZOOM C's Extended service update. Patch by Sam Reynolds.
1673 New options for ZOOM C's connection, logapdu which makes ZOOM log
1676 --- 3.0.34 2008/06/18
1678 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1680 --- 3.0.32 2008/06/12
1682 Fixed memory violation that could occur when decoding UTF-8. This bug
1683 was only present in 3.0.30 of YAZ.
1685 --- 3.0.30 2008/06/06
1687 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1688 GNU TLS is used by default (if found).
1690 yaz-ztest returns OPAC records if a client asks for OPAC.
1692 Improved speed of MARC-8 encoding.
1694 Added support for lossy and loss-less MARC-8 encoding.
1696 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1698 Added new Windows Service wrapper (sc).
1700 yaz-client's itemorder command may now send a file.
1702 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1704 Added new function yaz_log_xml_errors.
1706 Allow (but warn) unknown XML attributes in MARCXML parsing.
1708 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1710 The UTF-8 to MARC-8 conversion now uses a different set of characters
1711 for Greek symbols. Bug #2120.
1713 --- 3.0.26 2008/02/21
1715 Added yaz_daemon (daemon.h).
1717 Fixed bug #2068: pkg-config trouble
1719 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1721 --- 3.0.24 2008/01/28
1723 Document --with-xml2 option.
1725 Added OPAC XML XSD (etc/opacxml.xsd).
1727 Allow glob mask for name attribute in retrieval element for the
1728 generic frontend server's retrieval facility.
1730 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1731 except POLLIN/POLLOUT.
1733 Fixed error handling in cs_listen. Bug #2037.
1735 --- 3.0.22 2008/01/20
1737 Fixed version in yaz/yaz-version.h.
1739 Fixed bug #2027: Crash when closing connection.
1741 Changed configure so that ICU support is only enabled if only ICU
1742 and Libxml2 is available (because the ICU chain is XML based).
1744 --- 3.0.20 2008/01/15
1746 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1747 is built. Only this DLL depends on the ICU runtime.
1749 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1750 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1752 Changed license of CCL module to 'Revised BSD'. After consultation with
1753 remaining members of the original EUROPAGATE consortium, we are re-issuing
1754 the CCL module without a separate license. The software was developed by
1755 Index Data as part of a research project. The special license was included
1756 to help feed usage information back to the project consortium to support
1757 project evaluation. At this time, the project consortium has long-since
1758 disbanded, and the majority of the original principals have retired. At the
1759 same time, we have significantly modified the software during the following
1760 years, to the point where very practically no original code remains. To
1761 simplify re-use of the software, we have contacted those members of the
1762 consortium who could be reached, and agreed to re-issue the module as a
1763 proper part of the YAZ package.
1765 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1767 CQL closer to being version 1.2 compliant. CQL also allows free-form
1768 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1771 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1772 bug could make Extended services handling crash in the ZOOM layer. This
1773 bug was only present in YAZ 3.0.18.
1775 --- 3.0.18 2007/12/19
1777 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1780 yaz-marcdump reads and writes collection wrapped records.
1782 Handle OPAC for record conversion module.
1784 Fixes for ICU wrapper.
1786 Allow ICU libs to be controlled with --with-icu .
1788 --- 3.0.16 2007/11/12
1790 Added yaz_poll which is a wrapper for select/poll. When poll is available
1791 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1792 sockets to be in use.
1794 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1795 functionality through an XML based configuration (ICU chain). This system
1796 is useful for search facilities such as Pazpar2 and Zebra that needs to
1797 perform tokenization of indexed material. The ICU code in a separate
1798 library libyaz3_icu.a.
1800 Added HTTP tunnel facility for COMSTACK, bug #1752.
1801 This is a facility that allows a Web proxy, such as squid, to tunnel
1802 Z39.50 traffic. This facility is "transparent" to must applications
1803 using YAZ. It's enabled by using pseudo transport connect: followed by
1804 the proxy address, followed by command, then follwed by he regular
1805 "virtual" addresss. For example,
1806 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1808 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1810 --- 3.0.14 2007/09/21
1812 Fixed bad memory reference in ZOOM_record - cuased by member not being
1813 initialized. This was a problem only in YAZ 3.0.12.
1815 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1816 fields were not removed.
1818 Changed the way C code is generated from codetables.xml. Made a MARC-8
1819 conversion trie for each characterSet section rather than codeTable.
1820 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1821 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1823 --- 3.0.12 2007/09/12
1825 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1826 from ZOOM_record_error).
1828 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1830 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1832 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1834 Better SRW-to-Bib-1 diagnostic mapping.
1836 ZOOM C and yaz-client announces SRU version 1.2 by default.
1838 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1841 Fixed in yaz_sru_decode to allow other version than 1.1.
1843 --- 3.0.10 2007/08/22
1845 Added support for SRU scan for ZOOM.
1847 Added support for the use of the older versions or Extended Service
1848 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1849 set to the version , 1=first, 2=second, 3=third. The third version is
1850 what ZOOM C has used so far. And that, obviously, is the default.
1852 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1853 therefore in Zebra and in SimpleServer-based applications). The new
1854 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1855 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1856 which is passed into the back-end search callback function.
1858 Added support for HTTP Basic authentication in clients: the SRU/W
1859 codec encodes the username/password elements of the PDU structure
1860 appropriately, and these may be set using the "user" and "password"
1861 options in ZOOM-C applications (the same options that are used for
1862 Z39.50 authentication).
1864 --- 3.0.8 2007/06/25
1866 Fixed bug #1208: SSL appears to be broken in ZOOM.
1868 Fixed bug #1206: Libxml2 include path weirdness.
1870 Added oid_name_to_dotstring.
1872 Allow elementSetName to be specified for ZOOM C record update.
1874 Allow waitAction to be specified for ZOOM C based for Extended Services.
1876 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1877 syntax OID. Bug introduced in YAZ 3 series.
1879 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1881 --- 3.0.6 2007/06/06
1883 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1884 directory. yaz-client now reads commands from file given by option -f
1885 if specified; then tries to read .yazclientrc in current directory.
1886 Failing that, it reads .yazclientrc from user's home directory.
1888 Added support for correlationInfo Note and ID for Record Update via
1891 Added yaz-client command querycharset which specifies character set for
1892 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1893 (termListAndStartPoint).
1895 Charset ISO5428:1984 is an alias for ISO5428-1984.
1897 Implemented a way to perform scan in a result set using Z39.50. This
1898 is achieved by attaching the result set name in the characterInfo
1899 (type InternationalString) of OtherInformation in the Scan Request PDU.
1900 The result set is identified in the otherinformation by the new OID:
1901 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1902 This allows for scan in result set and faceted search . Zebra did some
1903 of this in the APT term using attribute type 8 and value being result
1904 set. Using the OtherInformation approach for this is cleaner and easier
1905 to work with in proxies and the like. This facility can be used in
1906 yaz-client using new command setscan which takes a result set as first
1907 argument, start position (APT) as second.
1909 Changed decoding of SRU XML packed records to deal with servers that
1910 have recordData with XML data with multiple root nodes. Also make
1911 comparison for recordPacking case insensitive. Again, one server
1912 returns "XML" where others return "xml".
1914 For SRU responses allow Content-Type application/xml as well as text/xml.
1916 --- 3.0.4 2007/05/21
1918 Fixed bug in character set conversion of BER strings. Bug introduced
1921 --- 3.0.2 2007/05/08
1923 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1925 For OID class, use oid_class consistently.
1927 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1930 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1931 character set for bibliographic information interchange". By Giannis Kosmas.
1933 Added documentation on new OID API.
1935 --- 3.0.0 2007/05/02
1937 Changes to generic frontend server interface: added new member
1938 'query_charset' for bend_initrequest structure. A backend init handler
1939 should set this member to its native character set for query terms.
1940 When defined, the frontend server logic will announce this character set
1941 to a client if the negotiationModel bit is set by the client. All server
1942 implementors are encouraged to specify this. If a backend server does not
1943 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1945 Added CCL utility to remove terms (stop words) from resulting RPN
1946 tree. This is handled by functions with prefix ccl_stop_words_ .
1948 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1949 terms in RPN queries.
1951 Clean-up the CCL API. Moved some internal structures from ccl.h to
1952 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1953 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1954 This is replaced by ccl_parser_find_str which takes a string instead.
1956 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1957 libyaz.la is the core of YAZ except the generic frontend server and
1958 does not depend on POSIX threads anymore. libyaz_server.la is the
1959 generic frontend server facilities and uses POSIX thread functionality
1960 if available. The libyaz.la no longer depends on POSIX threads because
1961 the number of global structures is limited. NMEM no longer re-uses blocks
1962 between threads ; it simply free's memory immediately but allocates in
1963 "large" chunks as usual. We don't expect any performance penalties
1964 because of this. The yaz_log system is still using a global log_level so
1965 caution must be taken when modifying it with yaz_log_init_.. +
1966 yaz_log_mask_str. This, however, should not cause any trouble because
1967 these functions are called during initialization of application code
1968 anyway. `yaz-config --libs server` returns libs for server applications;
1969 `yaz-config --libs` returns libs for non-server applications.
1971 New OID database - with public definitions in oid_db.h. Removed old OID
1972 database including the head oid.h and definitions such as enum oid_value
1973 and struct oident. The new OID database uses the same string names as
1974 before but the 'protocol' is gone. There are now only two representations
1975 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1976 converts from string to OID; functions with prefix yaz_oid_to_string
1977 converts the other way.
1979 Change to emit_term() in CQL-to-PQF query translation: when a term has
1980 the /regexp relation modifier, do not process it for leading and
1981 trailing "^" and "*", which have quite different meanings in regular
1984 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1985 write handlers no longer carries a 'last' parameter. This will make
1986 yaz_iconv flush "less" characters. A flush is performed by call to
1987 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1989 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1990 removed, because function yaz_query_to_wrbuf does the same.
1992 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1993 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1995 Deprecated MARC utility functions removed.
1997 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2000 Branch split: YAZ_2_1_55_branch
2002 --- 2.1.54 2007/03/16
2004 Fix to ZOOM-C so that transparent reconnection is properly handled on
2005 connections that are in asynchronous mode.
2007 Fixed compilation on OpenBSD 4.0.
2009 Large strings in GRS-1 records are now properly displayed in yaz-client.
2011 Added character conversion support for "advancegreek"; based on patch from
2014 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2015 sequence is met. Before the error was not set so it would be unknown.
2017 Adjust yaz-marcdump MARC reader so that it skips until record separator
2020 --- 2.1.52 2007/03/07
2022 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2023 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2024 fd_set structure used as a bitmask for the FDs to be selected on.
2026 Using ACX_PTHREAD macro to check for POSIX threads.
2028 Fixed have-vsnprintf check.
2030 --- 2.1.50 2007/02/23
2032 Fixes for configure on BSD. Bug #900.
2034 Added snprintf/vsnprintf wrappers for systems that don't have
2035 limits (heavens forbid).
2037 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2038 created before all previous tasks were completed and removed from the
2039 task queue, the new task could be removed by a mistake.
2041 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2043 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2045 Fixed bug #832: Problem with MARC/charset in yaz-client.
2047 Fixed bug #668: save command line history for yaz-client.
2049 Fixed bug #830: pkg-config support.
2051 --- 2.1.48 2007/01/23
2053 Extended ZOOM result set options with two options that may be read by
2054 a client: resultSetStatus and presentStatus with values as specified for
2056 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2058 Fixed bug #827: Using SSL fails on Debian etch.
2060 Fixed bug #826: Weird looking chars for set of MARC records.
2062 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2063 that is treated as an ItemOrder with itemRequest being an XML document
2064 external. The value of "doc" is the content.
2066 Extended the GFS search facility. New member of bend_search_rr
2067 'estimated_hit_count' signals that hits is known to be an estmate
2068 (higher or lower than real hit count). New member 'partial_resultset'
2069 signals that the search was partial (hit count is lower or equal than
2070 real hit count). For Z39.50, the information is stored in resultSetStatus
2071 member of SearchResponse APDU. For SRU, the information is signalled
2072 via SRU diagnostic 59: "Result set created with valid partial results
2075 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2077 --- 2.1.46 2007/01/13
2079 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2081 Added ZOOM_connection_peek_event.
2083 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2084 the following new functions:
2085 ZOOM_event_nonblock, ZOOM_connection_process,
2086 ZOOM_connection_get_{socket,mask,timeout},
2087 ZOOM_connection_fire_event_{timeout,socket}.
2088 The existing blocking event handler, ZOOM_event, is a wrapper for the
2089 + blocking ZOOM_event_sys_{poll,select}.
2091 Implemented function ccl_xml_config which parses XML version of CCL
2092 configuration (bug #798).
2094 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2096 Added timings utility (yaz/timing.h)
2098 --- 2.1.44 2007/01/03
2100 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2103 Fixed bug #779: Rotation of apdu.log fails.
2105 Fixed for character set conversions:
2106 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2107 Honor G1 set in MARC-8 decoding.
2109 --- 2.1.42 2006/12/17
2111 Fixed bug #775: char conversion does not handle Alternative UTF-8
2114 Implemented function yaz_marc_read_line which parses MARC line format
2115 records. There is a wealth of formats out there. So far, this function
2116 reads line records produced by yaz_marc_write_line.
2118 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2119 more generic and easier to remember(!) options: -i format and -o format
2120 which specifies input format and output format respectively - where
2121 format is one of "marc", "marcxml", "line", "marcxchange".
2123 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2124 does not print anything except warnings for records.
2126 For yaz-marcdump, added support for MARC split into files (-s) with a given
2129 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2130 spec, at http://www.loc.gov/standards/sru/record-update/
2131 This has changed the binary layout of the following structs:
2132 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2133 bend_update_rr . Patch by Ko van der Sloot.
2135 Added GFS utility function bend_assoc_is_alive which returns 1 if
2136 association is still alive (client is connected); 0 otherwise (client
2137 closed connection). This allows busy servers to stop working for
2140 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2141 been a separate piece of software. This version of ziffy has been modified
2142 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2144 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2146 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2147 Client code may now interrogate options such as "init_opt_sort" to
2148 find out whether the server claims to support various options.
2150 --- 2.1.40 2006/11/27
2152 Added utilities yaz_{set,get}_esn to set/get element set name from
2155 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2156 of YAZ and has been so since YAZ 2.1.10.
2158 Implemented ZOOM_record_error which returns error information for
2159 record (surrogate diagnostic).
2161 --- 2.1.38 2006/10/31
2163 Updates for SRU Update by Ko van der Sloot:
2164 1. Changed name from "operation" to "action"
2165 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2166 versions in the code, marked as 'backward compatible'.
2167 3. Added diagnostics for SRU Update.
2169 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2171 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2173 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2175 For GFS, fixed problem with SRU diagnostic 'First record position out of
2176 range' being issued for 0 hits.
2178 zoomtst10 part of Windows Build.
2180 --- 2.1.36 2006/10/13
2182 Implemented yaz_filepath_comp which splits a path into file path
2183 components (required by Zebra 2.0.3+).
2185 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2186 BSD inspired license until now so this should not have any real impact on
2187 anybody. See http://www.opensource.org/licenses/bsd-license.php
2189 Fixed bug #687: Missing log lines.
2191 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2194 Fixed bug #689: SRU diagnostics to be added.
2196 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2197 whether a connection is idle (no more work do do).
2199 --- 2.1.34 2006/10/04
2201 Change type of optval from long to int for invocation of setsockopt with
2202 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2204 Added support for specifying the max log file size for the Generic
2205 Frontend Server. The size is given with option -r.
2207 --- 2.1.32 2006/09/21
2209 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2211 --- 2.1.30 2006/09/17
2213 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2216 Fixed bug in Generic Frontend Server that could cause a server to stop
2217 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2219 For the generic frontend server, the maximum record size is used as maximum
2220 size of incoming packages (SRU + Z39.50). The value until was previously
2221 only used in Z39.50 Init negotiation and, later, in a session controlled
2222 sizes of records returned. This is controlled using -k option. It can be
2223 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2225 --- 2.1.28 2006/09/04
2227 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2230 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2232 New option for yaz-marcdump -lpos=value which allows setting a portion
2233 of MARC header to a certain value.
2235 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2237 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2238 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2240 --- 2.1.26 2006/08/15
2242 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2245 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2247 --- 2.1.24 2006/08/08
2249 Fixed MARC ISO2709 encoding routines to deal with character set
2252 Minor changes to GFS logging. Database included in search request log
2255 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2256 cached/multiple records.
2258 Shared libraries are built by default on Unix+configure.
2260 Changed cql2pqf transformation to use a different evaluation order. The
2261 new order is: always, relation, structure, position, truncation, index
2262 and relationModifier. Old order was: always, relation, relationModifier,
2263 structure, index, position, truncation. Note that the the latter ones
2264 override former ones for identical attributes.. The new scheme means that
2265 it is possible to override any existing attribute with a relationModifier.
2266 And also that it is possible to override everything for the index rule
2267 (except the ones listed in relationModifier). No order is perfect but this
2268 one, we believe, covers more real cases.. The "always" should have been
2269 called "default", since the attributes there can be overridden with all
2272 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2273 compilation phase, but also for yaz-config --cflags output. This allows
2274 us to have public headers with Libxml2 stuff in them . It should also,
2275 eventually, make Libxml2 checks redundant in packages using YAZ, such
2278 --- 2.1.22 2006/06/15
2280 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2281 stored in uri, message and details.. Previously diagnostics were stored
2282 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2283 compatibility.. but he's probably the only one affected, so.
2285 Added support for CCL, compiled on the client side, in ZOOM-C. This
2286 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2287 input; the resulting query objects can be used for for searching with
2288 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2290 YAZ' configure searches for OpenSSL by default.
2292 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2293 SL_CTX_use_certificate_file. See
2294 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2295 for more info. Thanks to Ko van der Sloot.
2297 --- 2.1.20 2006/06/02
2299 Bug #600: SRU GET, POST support for yaz-client. Introduced
2300 command 'sru' which selects method SOAP/GET/POST.
2302 Allow missingValueAction to be specified for the sortspec string -
2303 function yaz_sort_spec. By default, the missing value action is null.
2304 Use ! to specify "abort". Use = followed by stringvalue to specify default
2307 Ensured that Present-handler (if defined) is called in GFS before any call to
2308 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2309 searchRetrieve requests.
2311 Documentation for YAZ is now based on the Docbook XML/XSLT using
2312 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2313 is no longer depending on jade/openjade or docbook-to-man scripts.
2314 PDF is no longer part of the distribution - but can optionally be
2315 made using DSSSL/jadetex or FOP.
2317 Added retrieval handling support in Generic Frontend Server to support
2318 conversion between MARC/XML as well as XSLTtransforms. See
2319 etc/yazgfs.xml for an example.
2321 Added Authentication support to Generic Frontend Server in SRU
2322 mode. Authentication using HTTP Basic is supported, as is the use
2323 of 'x-username' and 'x-password' parameters in the request itself.
2325 Added support for a new character set MARC8s identical to MARC8 except
2326 that it converts combined characters to single Unicode characters in the
2327 Latin-1 range (when possible).
2329 --- 2.1.18 2006/04/24
2331 ASN.1 compiler 0.4: generates brief Doxygen file header for
2332 generated .h/.c files.
2334 Utility yaz_iconv now supports conversion to MARC-8.
2336 New facilities for the MARC module. The reading - and writing of
2337 content are separate methods for the yaz_marc_t handle. The following
2338 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2339 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2340 format). Write functions have prefix yaz_marc_write_.. The existing
2341 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2342 available. Removed support for OAI-MARC and simplexml (not the
2343 simplexml from PHP5).
2345 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2346 to be returned for this connection.
2348 --- 2.1.16 2006/03/31
2350 Allow multiple languages and charsets to be specified with
2351 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2352 negcharset iso-8859-1,utf-8
2354 Translation of proximity nodes from CQL into PQF now works.
2356 Moved to automake 1.8, 1.9.
2358 Added function yaz_log_set_handler which allows a log handler to be
2359 installed. This handler will be called for all log messages. Output
2360 to file is also produced; but that can be disabled by passing NULL
2361 fname to yaz_log_init_file.
2363 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2365 For SRW (including GFS), accept application/soap+xml as content-type
2368 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2369 produces NO stylesheet reference even if a default stylesheet is specified
2372 --- 2.1.14 2006/03/14
2374 Updated Windows package to include yazd.dll + yazd.lib for the
2375 Development component.
2377 If the environment variable YAZ_LOG is set, then it is used as a
2378 string indicating the default level of logging to use if not
2379 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2380 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2381 used as before. So, for example, to omit warnings from YAZ logging,
2382 export YAZ_LOG=-warn
2384 cql_transform() now map structure and other attributes before indexes,
2385 so that index-specific structures and other attributes can override
2386 defaults. So now a combination of mapping specifications such as:
2388 index.dc.date = 1=date-modified 4=5
2389 does the right thing.
2391 cql_transform() now also respects the "always" mapping specification,
2392 which establishes an initial set of attributes to be used for all
2393 terms except where overridden by more specific attributes associated
2394 with the index, relation or modifier.
2396 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2397 which mode to use; one of "post", "get" or "soap" (SRW, default).
2399 Fixes for yaz_iconv routines: changed trie-based character set conversions
2400 to use only non-negative values for bit fields due to Sun's C compiler not
2401 supporting negative values.
2403 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2404 sequences where not read correctly. Fix by Rustam Usmanov.
2406 Updated win/makefile to use options, settings which makes things
2407 compile with VS C 2005.
2409 --- 2.1.12 2006/02/01
2411 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2413 In ZOOM socket code, use select instead of poll on MacOSX.
2415 ZOOM-C now support client-side compilation of CQL into RPN that is
2416 sent to the server, enabling CQL to be used against all Z39.50
2417 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2418 ZOOM_query object, and submit it using ZOOM_connection_search().
2419 The CQL-to-RPN translation uses a configuration file, the name of
2420 which must be specified in the Connection's "cqlfile" option.
2422 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2423 function, which takes as its start-term parameter a ZOOM_query object
2424 (which may have had either CQL or RPN set into it).
2427 --- 2.1.10 2005/11/29
2429 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2430 GFS to support this as well. Backend handler, bend_srw_update, does the
2431 update work. Code contributed by Ko van der Sloot.
2433 Allow retrieval of Search Result-1 information in ZOOM by the use of
2434 options that are attached to a result set. ZOOM documentation updated
2437 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2438 UTF-8 conversion. Patch by Raj Patel.
2440 Added option -m to GFS to control formatting of timestamps in log file.
2442 Added 'exit' as synonym for 'quit' in yaz-client
2444 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2445 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2446 for the new members. Patch by Ko van der Sloot.
2448 Added support for SRU POST. It is supported for content-type
2449 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2451 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2452 Instead make the library libyaz.la multi-threaded. Threading as a whole
2453 can still be disabled by configure option --disable-threads. Previosly,
2454 with older GLIBCs there were problems with MT libs under Apache. This
2455 has now been fixed a long time ago.
2457 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2460 CQL module modified to be case insensitive for relations/indexes/operations.
2462 Fixed bug in CQL transform code: incorrect value relationModifieder
2465 Added 'show all' command for yaz-client which retrieves all results
2468 Added new yaz-client, xmles, which takes a (private) OID and
2469 a document to be sent as an extended service request.
2471 Describe new yaz-client commands wait_response and set_auto_wait.
2473 Increase TCP/IP listener backlog from 3 (which I am guessing was
2474 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2475 that the socket will queue as many incoming connections as it's able
2476 to handle ongoing connections. In other words, it will never now
2477 refuse a connection that it would be able to handle merely because
2478 it's not got around to accepting() enough of the pending connections
2479 yet. This is the behaviour anyway under Linux, where the listen()
2480 argument is ignored; but not under BSD and on systems such as
2481 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2482 YAZ-based servers should now be uniform across operating systems in
2485 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2486 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2487 This allows yaz-marcdump to read large MARC batches (>2 GB).
2489 Modified all YAZ source files - except the source which is auto-generated
2490 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2493 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2494 corresponding to the existing *_setl() function. These allow option
2495 values containing arbitrary valuues.
2497 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2498 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2499 except that it returns an indicator of whether or not the sort
2500 criterion was accepted (0 for OK, -1 for invalid).
2502 --- 2.1.8 2005/06/07
2504 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2505 MARC output rather than returning "new" buffer.
2507 yaz-client warns about unknown init options.
2509 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2511 --- 2.1.6 2005/05/24
2513 Added support for SRW sort in Generic Frontend Server. Patch
2514 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2515 sortKeys - or NULL if none is provided.
2517 Fixed bug #307: It was impossible to specify indefinite/no timeout
2518 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2521 Added support for multiple languages and charsets to be specified in
2522 ZOOM. Each charset/language is separated by a blank. If negotiation is
2523 in effect in init-response, Option
2524 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2525 Code based on patch by Vasiliy Osadchuk.
2527 Fixed bug #306: infinite recursion that occurred when calling
2528 yaz_log_level_init as the first call (before other log level or
2531 Fixed bug in scan handling in front end server: if preferred-Position-In-
2532 Response was non-present, a NULL pointer referece was performed.
2534 --- 2.1.4 2005/04/26
2536 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2537 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2538 now defined for all those error codes. So instead of putting 109 in
2539 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2540 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2542 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2545 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2547 Program yaz-client now exits and produces an error message if multiple
2548 Z39.50 servers are specified on the command line (none or one allowed
2551 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2554 --- 2.1.2 2005/03/16
2556 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2558 Fixed bug #272: Preserve spacing for CCL terms.
2560 --- 2.1.0 2005/03/14
2562 Added support for virtual hosts and multiple backend servers for
2563 the YAZ frontend server. The configution is XML based and
2564 support specificition of CQL to RPN mappings and explain information.
2565 See section "Virtual Hosts" in the YAZ manual.
2567 Extended OPAC display utility. OPAC display utility renders
2568 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2569 to supplement yaz_marc_decode_wrbuf.
2571 Fixed a bug in MARC decoder that could caused it to crash for some
2572 invalid MARC records. More diagnostics and warnings where added in
2573 XML output (warnings, etc are stored in comments).
2575 --- 2.0.34 2005/02/08
2577 Fixes for UNIX domain sockets. Bug #261.
2579 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2581 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2582 Added yaz_marc_subfield_str which defines subfield lead string which is
2583 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2584 yaz_marc_endline_str which defines end of fields string used in
2585 YAZ_MARC_LINE format. Default string is newline.
2587 Experimental support for MarcXChange. This format can be produced
2588 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2589 http://www.bs.dk/standards/MarcXchange.xsd
2591 Added yaz-client commands scansize that sets maximum number of
2592 entries to be returned by scan.
2594 --- 2.0.32 2005/01/11
2596 Added support for SRW scan in yaz-client and Generic Frontend Server.
2598 * Added whereInList member to SRW Scan Term.
2600 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2602 Fixed NMEM system to return aligned blocks on the smallest boundaries
2603 that are suitably aligned for all possible types on the particular
2604 architecture YAZ is being built for.
2606 --- 2.0.30 2005/01/04
2608 Fixed numerious warnings that was issued with newer versions of GCC.
2610 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2611 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2614 Make YAZ Generic Frontend Server slightly faster.
2616 Enhance (and reduce) logging for Generic Frontend Server.
2618 Revert YAZ log system so that it flushes every write operation
2619 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2621 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2622 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2623 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2624 will effectively disable old definitions.
2626 --- 2.0.28 2004/11/09
2628 Added yaz_log_time_format which specifies log format using
2631 Added yaz_log_module_level which returns mask for a module. Value
2632 is non-zero mask a if module is enabled; zero if disabled.
2634 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2635 in include/yaz/cql.h.
2637 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2639 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2641 Fixed bug #172: RPM builds does not enable SSL.
2643 Doxyfile.in part of dist. Doxyfile generated by configure.
2645 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2646 are given and the corresponding component does not exist.
2648 Extend CCL documentation in YAZ reference. Describe r=r.
2650 --- 2.0.26 2004/10/01
2652 Fixed MARC->MARCXML conversion to properly deal with
2653 fields, subfields, indicators having non-ASCII characters.
2655 Fixed MARC->MARCXML conversion so that ASCII control characters
2656 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2659 Added YAZ GFS support for conversion from Z39.50 surrogate
2660 diagnostics to SRW surrogate diagnostics.
2662 Bug fix: YAZ GFS did not return schema in explainResponse.
2664 --- 2.0.25 2004/09/30
2666 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2667 now converts recordSchema to elementSetName as well as schema URI.
2669 Fixed bug in COMSTACK that prevented HTTP request packages from being
2672 --- 2.0.24 2004/09/29
2674 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2675 does not require white-space before and after the dash in a range, e.g.
2676 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2679 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2680 due to new GCC removing "redundant" code.
2682 Added yaz-client commands scanpos and scanstep that sets preferred
2683 position and step-size for scan.
2685 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2687 Added CCL utility ccl_qual_buf which parses one or more CCL
2688 spec lines in a buffer.
2690 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2691 of name and value - ignoring empty lines and comments.
2693 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2695 Added odr_get_element_path which returns current element path for an
2696 ODR handle. This utility is useful in error handling or user-defined
2699 Added ODR_PRINT utility odr_set_stream which is is a more generic
2700 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2701 to a write function and pointer to close function. The close function - if
2702 non-NULL - will be called during odr_destroy.
2704 Fixed bug in CCL parser where truncation char was not removed from
2705 right side when truncation=both was in effect.
2707 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2710 --- 2.0.23 2004/08/11
2712 Fix buffer overrun in CQL parser when dealing with proximity (%).
2714 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2715 to UTF-8/UCS conversion is now only based on codetables.xml.
2717 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2719 --- 2.0.22 2004/08/06
2721 Add support for more "commit changes" in ZOOM (uses Extended Services).
2723 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2726 Yet another small fix for configure of SSL.
2728 --- 2.0.21 2004/05/14
2730 Fix SSL libs for configure when --with-openssl=DIR is given.
2732 --- 2.0.20 2004/05/10
2734 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2736 SSL comstack now uses yaz.pem certificate file on server side
2737 by default. Certificate filename can be configured by calling
2738 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2740 Fix bug regarding multiple calls to ZOOM_connection_connect.
2742 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2744 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2745 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2747 ZOOM now allows inspection of X509 peer certificate for verification.
2748 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2750 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2751 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2752 as "modular" but it simplifies things.
2754 Added cs_get_peer_certificate to that returns peer X509 PEM.
2756 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2757 NULL if SSL is unavailable.
2759 Documentation about MARC decoding tools.
2761 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2763 --- 2.0.19 2004/03/30
2765 Rename CHANGELOG to NEWS to follow GNU style packing.
2767 Fix bug with missing initialization of member in init_diagnostics.
2768 This bug affects threaded version of GFS server.
2770 --- 2.0.18 2004/03/20
2772 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2775 Ensure zlib.dll is packed with Windows install.
2777 --- 2.0.17 2004/03/17
2779 Fix encoding of xsd:string to use text instead of CDATA.
2781 Fix endless loop in CQL parser with unbalanced ".
2783 Use a more compact way to store MARC-8 conversion tables.
2785 --- 2.0.16 2004/03/16 Debian only
2787 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2790 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2795 --- 2.0.15 2004/03/01
2797 Another fix for decoding of XML packed records.
2799 --- 2.0.14 2004/02/25
2801 Fixes for Chunked encoding. White space not ignored after length spec.
2803 Update NS and use default NS for SRW diagnostic elements.
2805 --- 2.0.13 2004/02/23
2807 Implement ZOOM_resultset_cache_reset which resets record cache.
2809 Implement ZOOM_resultset_sort which sorts a result set.
2811 Implement chunked HTTP transfer.
2813 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2815 --- 2.0.12 2004/02/16
2817 Added member 'schema' to bend_explain_rr structure so that backend
2818 can specify explain record identifier. Defaults to Zeerex 2.0.
2820 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2822 --- 2.0.11 2004/02/16
2824 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2827 Added init command for yaz-client which sends "extra" init request.
2829 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2830 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2832 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2834 Make ZOOM error code for "invalid query".
2836 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2838 --- 2.0.10 2004/02/05
2840 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2843 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2845 Added option -p <file> to make Generic Frontend Server to write PID file.
2847 Added option -D to put Generic Frontend Server in background on its own.
2849 Make ZOOM C recognize option "password". If unset, "pass" is used
2850 (for backwards compatibility).
2852 Fixed a bug in Generic Frontend Server that could make it crash if a
2853 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2856 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2857 Must be issued before open, in order to be in effect.
2859 --- 2.0.9-6 2004/01/12 Debian/Windows
2861 Make the SRU server more picky WRT unknown params, etc.
2863 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2865 New YAZ client command, options, that sets Z39.50 options.
2867 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2868 options from a string of tokens (one token for each option bit).
2870 Update SRW diagnostic code messages.
2872 --- 2.0.9-5 2004/01/07 Debian/Windows
2874 Handle user defined stylesheet for SRW/SRU.
2876 --- 2.0.9-4 2004/01/06 Debian/Windows
2878 Fix bug in decoding of Content-Length.
2880 --- 2.0.9-3 2004/01/06 Debian/Windows
2882 Fix a bug with decoding of XML packed records.
2884 --- 2.0.9-2 2004/01/05 Debian only
2886 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2888 Fix bug in SRW/SRU diagnostics decoding.
2890 --- 2.0.9 2004/01/05
2892 Fixed bug in Generic Frontend Server which could drop records exceeding
2893 preferred message size. Reported and fixed by Irina Dijour.
2895 Fixed calculation of package size for structured records in Generic
2896 Frontend Server. Reported and fixed by Irina Dijour.
2898 Fixed namespace for SRW/SRU diagnostics.
2900 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2902 --- 2.0.8 2003/12/22
2904 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2905 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2908 CQL changes to reflect recent changes to the specification:
2909 * Documentation talks about context sets instead of index sets.
2910 * Documentation talks about indexes instead of qualifiers.
2911 * The CQL-to-PQF transformer's configuration file now uses
2912 "index.set.name = <attributes>" instead of the old form
2913 "qualifier.set.name = <attributes>". (Both forms are still
2914 understood but the latter is deprecated.)
2915 * CQL terms with no explicit index specified are now interpreted as
2916 cql.serverChoice instead of srw.serverChoice (which of course
2917 behaves exactly the same.)
2919 --- 2.0.7 2003/12/16
2921 MARC conversion can now generate ISO2709 output in another
2922 character set. yaz-marcdump uses this facility if you invoke it
2925 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2926 functions from there can be used from C++.
2928 --- 2.0.6 2003/12/04
2930 Frontend server now transfers memory from decoded packages to stream
2933 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2934 references to show up.
2936 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2937 the ZOOM Abstract API. The older names for the same options are still
2938 also supported for the benefit of old applications.
2940 ZOOM-C supports "implementationId" and "implementationVersion" options
2941 to go along with "implementationName". These allow the user code to
2942 specify identification strings to be sent to servers.
2943 Add OID for the new ExtLite attribute set.
2945 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2946 as requested/supplid by Ere Maijala <ere@atp.fi>
2948 For generic frontend server, reverse the order of
2949 "toolkit-supplied / application-supplied" strings sent as implementationId,
2950 Name and Version. Also, remove the spaces around the slash. This brings
2951 the GFS in line with the behaviour of ZOOM-C on the client side.
2953 Add function ZOOM_scanset_display_term.
2955 yaz-client shows scan displayTerm if present.
2957 Utility yaz-iconv is now installed by default along with the man page
2960 Extend configure check for OpenSSL to use pkg-config where available (such
2963 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2964 server to specify uid/gid/mask for socket using the format
2965 unix:[user=uid,][group=gid,][umask=mask,]file=path
2966 If file= is omitted the existing format is assumed, e.g.
2968 in which case the mask is 0666 (rw for everybody).
2970 Major restructure of YAZ source. All source in libyaz is in src directory.
2971 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2972 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2974 Added man page for utility yaz-marcdump (used to be called marcdump).
2975 yaz-marcdump is installed by 'make install'.
2977 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2978 of incoming package failed.
2980 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2982 Change prototype of odr_perror: add const to message string.
2984 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2986 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2987 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2988 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2989 DNS lookup. There should not be any compatibility problems with this
2990 assuming that blocking=1 or 0 is used.
2992 Fix bad reference in UNIX comstack in function cs_addrstr.
2994 Fix for compilation on AIX.
2996 The generic front-end server (server/seshigh.c) now supports returning
2997 Init diagnostics to the client in User-information-field, in
2998 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3001 --- 2.0.4 2003/09/04
3003 Allow any CQL relation (not just all,any,exact,scr).
3005 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3006 that features the same UI.
3008 Implemented command update0 in YAZ client which is equivalent to
3009 update but uses old of Ext Update ASN.1.
3011 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3012 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3013 Previously no OID was used for this info.
3015 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3016 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3017 returns 'malformed search term' otherwise.
3019 SortResponse member resultCount now set to NULL in sort handler of
3022 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3025 Add three new utility functions for translating OIDs between various
3026 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3027 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3028 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3029 char *oid_to_dotstring(const int *oid, char *oidbuf);
3030 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3032 Reverted modifications for ES Update definition for z_IU0Update
3033 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3034 is back to YAZ 2.0.2.
3036 String value attributes for CCL parser.
3038 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3039 which their FirstSearch server returns in Init responses, sometimes
3040 carrying useful diagnostic information when Init fails. This has the
3041 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3042 "z39.50/oclcui.asn", where its definition is somewhat different from
3043 what OCLC document on their web-site, as required to interoperate with
3046 Support for anonymous authentication in yaz-client. Use the command
3049 * Fix the OID of the Index Data-local "admin" Extended Service from
3050 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3051 the 1000, which indicates a locally-defined OID, was a mistake.
3053 --- 2.0.3 2003/06/20
3055 Fix CCL directive @case handling so that it affects string match for
3056 both CCL keywords and qualifiers.
3058 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3059 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3060 Decoder has been updated with ASN.1 changes as listed in
3061 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3062 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3063 z_IUUpdate, remains unchanged.
3065 ZOOM_record_get may now return a record in a specific character set.
3066 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3067 "from" is the character set of record as returned by target. "to" is
3068 the character set to be returned. If omitted, "to" is UTF-8.
3070 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3072 New ODR utility, odr_getelement, which returns name of element for
3073 which encoding/decoding failed.
3075 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3076 in cases where a required element was omitted.
3078 Bug fix: some MARC8 sequences were not converted.
3080 New ZOOM option "step" which specifies number of records to be
3081 retrieved in one chunk. Used in conjunction with "start" and "count".
3083 SRW support for yaz-client. Use scheme http: to use it, e.g.
3086 yaz-client no longer does (un)intelligent character set conversions
3087 by default. Can be enabled with charset and marc_charset commands.
3089 xmalloc trace fix for 64-bit systems such as DEC alpha.
3091 Solaris 2.6 compile fix.
3093 New function, cql_strerror() translates SRW error codes, as returned
3094 by cql_transform_error(), into human-readable English strings. Used
3095 in yaz-client diagnostics when appropriate.
3097 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3098 converts it into a type-1 query which is sent to the server. This
3099 makes CQL available for use with all Z-servers, as opposed to the tiny
3100 minority that can handle CQL queries themselves.
3102 --- 2.0.2 2003/04/28
3104 New Debian package layout similar to the Redhat Package layout.
3106 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3107 and search result respectively.
3109 --- 2.0.1 2003/04/25
3111 Redhat package is now several packages: libyaz (runtime libraries),
3112 libyaz-devel (development and documentation, and yaz (utility programs).
3113 Package spec file by Morten Bogeskov.
3115 New member 'schema' in struct bend_fetch_rr which the name of requested
3116 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3117 handler MAY set this to reflect the schema of the returned record.
3119 New member 'display_term' in struct scan_entry. GFS now sets member entries
3120 and allocates scan entries to be filled by user scan handler. In previous
3121 version, entries member was allocated by the scan handler. That still works,
3122 but the GFS will ignore member display_term - assuming it was NOT set by
3123 the handler. The fact that the GFS now allocates the entries both allows
3124 for new members and makes a scan handler easier to write.
3126 Fix CQL lex buffer overflow.
3128 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3129 SRU default recordPacking is string.
3131 SRU protocol support for frontend server.
3133 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3135 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3137 Added scan for the ZOOM shell (zoomsh).
3141 * String Identifers for Schemas (Amendment 5).
3142 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3143 Old definition for schema
3144 Odr_oid *schema; /* OPT */
3149 Z_InternationalString *uri;
3150 #define Z_Schema_oid 1
3151 #define Z_Schema_uri 2
3154 * resultCount parameter to Sort Response (Amendment 1).
3155 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3157 Support for SRW 1.0 over HTTP. This is an optional feature and
3158 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3161 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3162 on the same port. SRW SearchRetrieveRequests are mapped
3163 to bend_init,bend_search,bend_fetch,bend_close.
3165 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3167 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3168 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3170 ZOOM connections are SRW based if schem http is used for hostname
3171 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3172 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3174 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3175 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3176 distance=n, order=true/false, relation=le, prox unit=word. If
3177 n is omitted, distance 1 is used.
3179 Fixed problem with C compiler include path in wrong order.
3181 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3182 on Solaris. Patch from Ko van der Sloot.
3184 New MARC decode API. All new functions operate on a yaz_marc_t
3185 handle. The most important new functions are: yaz_marc_create,
3186 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3187 decode and destroy respectively. Decoder can produce formats
3188 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3189 include/yaz/marcdisp.h.
3191 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3192 to UTF-8, UCS-32, wchar_t or Latin-1.
3194 * Prototypes for yaz_iconv_-functions moved to separate header
3195 include/yaz/yaz-iconv.h.
3197 Make a few private functions 'static' in unix.c. This prevents
3198 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3200 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3201 are set when Init Response is received.
3203 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3204 but returns diagnostic set as well.
3206 New function yaz_strerror which is a portable wrapper for
3207 strerror/strerror_r/GetLastMessage.
3209 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3210 is returned for MARC. If type is "oai", then OAI MARC is returned.
3212 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3215 --- 1.9.2 2002/11/26
3217 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3219 Fix bad race conditions on SIGTERM and terminate gracefully in
3222 Move retrieval (data1) module to Zebra since nobody seems to be
3225 Add GRS-1 render for ZOOM using same format as yaz-client.
3227 --- 1.9.1 2002/10/05
3229 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3231 Fix broken ESpec handling in data1 module.
3233 SGML reader parses comments and makes them part of the data1 tree.
3235 Added several type casts so that YAZ compiles as C++ code.
3237 ZOOM didn't handle PDU encoding failures properly.
3239 Added more Bib-1 diagnostics (approved extensions).
3241 GNU configure: better check for iconv.
3243 More portable use of accept, getpeername. Check for socklen_t. Use
3244 int/size_t if socklen_t is not defined.
3248 PQF parser rejects bad queries - including those with extra
3249 characters in them. PQF parser used to silently ignore that.
3250 Cleaner API for PQF added, which allows you to get detailed
3251 error information for bad queries (see yaz/pquery.h).
3253 Fixed bug in ZOOM_record_get for type "database".
3255 Implemented mini iconv library supporting conversions between
3256 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3258 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3260 --- 1.8.9 2002/08/20
3262 Fixed ZOOM C record cache so that preferredRecordSyntax and
3263 elementSetName is used to check for already fetched records.
3265 --- 1.8.8 2002/08/02
3267 Added three members in bend_initrequest structure to facilitate
3268 character set negotiation.
3270 Fixed a bug in frontend server that could cause indefinite
3271 loops under rare conditions.
3273 Revised character set utilities (charneg.h) so that encoding
3274 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3276 For PQF, directive @term <type> sets term type for Scan/Search.
3277 Here <type> is general, string, numeric, null. The term type
3278 is inherited - just like @attr.
3280 New call odr_set_charset that sets character set conversion for
3281 international-strings on a ODR stream. Prototype is:
3282 int odr_set_charset(ODR o, const char *to, const char *from);
3283 The InternationalString is still represented as C string in YAZ
3284 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3285 won't). On the protocol level, you can use any encoding.
3287 Support for UNIX sockets in ZOOM.
3289 Solaris recv sometimes returns errno == ENOENT. It is treated as
3290 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3292 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3293 both client and server. Code by Morten Bogeskov.
3295 --- 1.8.7 2002/05/22
3297 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3298 that they can be used directly from Visual Basic. You must recompile
3299 your windows APP if you're using ZOOM.
3301 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3302 Commands "lang" and "charset" sets language and character set respectively.
3303 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3304 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3306 Attributes from multiple CCL fields may be OR'ed rather than merged
3307 using directive "@field or". Fields are still merged by default -
3308 equivalent to "@field merge".
3310 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3313 Fixed bug in zget for parameter ExtendedServicesResponse.
3317 --- 1.8.6 2002/03/25
3319 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3321 Client displays USR.1:SearchResult-1 (hits per term).
3323 Additional Search Info for search in Generic Frontend Server.
3325 Fixed CCL parsing of "field=s".
3327 WIN32 installer - using the excellent NSIS software from nullsoft.
3329 Fixed CCL parsing of "field = - <number>".
3331 Added function yaz_marc_decode that decodes MARC for line mode
3332 display or XML (similar to that used by JZKit).
3334 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3335 Z39.50. But ISO/ILL was, however.
3337 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3338 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3340 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3341 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3343 --- 1.8.5 2002/02/03
3345 New YAZ client features: Command completion and new commands:
3346 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3347 Code provided by Jacob Poulsen.
3349 New call oid_trav, that visits all registered OIDs via callback.
3351 Function ZOOM_record_get now returns const char pointer rather than
3352 void pointer. It saves a lot of type casts.
3354 For YAZ client, command "auth" now allows you to set authentication
3355 in IdPass style. It is enabled when three tokens are given - order
3356 is user, group and password.
3358 Fix memory leaks in MARC record handling for ZOOM.
3360 New option for YAZ client, -k <kilobytes> that sets
3361 maximum record size. Similar to -k option for generic frontend
3362 server and yaz-ztest.
3364 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3366 Prefix query parser reports "fail" when bad attribute set is given.
3368 Fix in MARC decoder. Proximity logging. Fix for attribute set
3369 in scan handler for server. Patches by Shigeru Ishida.
3371 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3374 Configure option --with-openssl=<dir> now works when a directory is
3375 specified. Patch provided by Morten Bogeskov.
3377 New option for YAZ client, -u <auth>, that sets authentication.
3379 ZOOM fix: error information was sometimes "missing", since error
3380 was cleared/reset too when it shouldn't.
3382 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3384 --- 1.8.4 2002/01/04
3386 Scan for ZOOM API. New object ZOOM_scanset. New functions
3387 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3388 ZOOM_scanset_destroy.
3390 New ZOOM function, ZOOM_connection_last_event, that returns type
3391 of last event (such as "receive data", "send data", "apdu received",
3394 New ZOOM option, schema, that specifies schema for retrieval.
3396 New CCL feature. Qualifiers can be aliases for one or more
3397 other qualifiers (if more than one is given, OR is used).
3399 ZOOM uses named result sets if target supports it.
3401 Two new YAZ client commands: . (dot, which sources a script of YAZ
3402 client commands), and ! (to execute shell command.). Implemented
3405 Working on Debian packages.
3407 --- 1.8.3 2001/11/19
3409 YAZ client enables named result sets only if target supports it.
3411 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3413 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3414 with key="host" to get same result.
3416 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3417 Function Z3950_resultset_record(s) returns references to records
3418 "owned" by resultset. To become owner use Z3950_record_clone.
3420 Function z_ext_record handles Extended Services. Thanks to
3423 --- 1.8.2 2001/11/12
3425 CCL Parser fix: ignore token comma when dealing with and-lists.
3427 Documentation updates for COMSTACK.
3429 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3430 Changed prototype Z3950_records. For some functions, int parameters
3431 were changed to size_t.
3433 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3436 New MARC decode/display function, marc_display_exl, which properly rejects
3437 non-ISO2709 records. YAZ client uses it.
3439 --- 1.8.1 2001/10/29
3441 Fix bug: local attribute set wasn't set correctly in PQF strings.
3445 * Old Z39.50 codecs no longer supported.
3447 Added ZOOM C binding. See http://zoom.z3950.org/
3449 Renamed states for COMSTACKs to avoid confusion with events.
3451 Implemented cs_look and proper cs_rcvconnect.
3453 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3455 Configure detects POSIX threads on OpenBSD.
3457 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3458 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3460 When error is returned from present handler, non-surrogate diagnostic
3461 is returned in present response (and fetch handler is no longer called).
3463 * Minor adjustments to pquery parser (PQF). Token characters may be
3464 escaped by using backslash (C-style).
3466 PQF parser allows string attribute values to be specified. For @attr,
3467 non-numeric characters after the equal-sign are treated as strings
3468 (e.g. @attr 9=title).
3470 CCL trunction character may be defined (@truncation in file)
3472 * function zget_ExtendedServicesRequest sets waitAction to
3473 waitIfPossible (was wait).
3475 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3478 CCL operator names may be set in field definition files (CCL_bibset).
3479 See ccl/bib1 for an example.
3481 Fixes in ASN.1 compiler for C++ compatibility.
3483 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3484 and "op_or" to avoid conflict with C++.
3486 Fixed problem with GNU readline detection on Redhat 7.0.
3488 Added step-size for Scan backend handler.
3490 Fixed bug that made the frontend server crash when no attribute
3491 set was specified for scan.
3493 Front-end server automatically switches to original working directory
3494 when installed as an NT service. Previously -w had to be specified to
3497 Added extended attributes for retrieval module (data1), so that data1
3498 records carry d1_readXML/SGML attributes. d1_read also supports
3499 null-data rules ( <tag/>)
3501 On UNIX when POSIX threads are available, a separate library libyazthread
3502 is created. Programmers should link with that library and the yaz library
3503 when using threads. The reason for the split was that some applications
3504 on Linux, such as Apache, doesn't work well when using shared objects that
3507 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3508 (or any frontend server) in SSL mode by specifying ssl: followed by
3509 address. Only tested on UNIX.
3511 Added feature for CCL module. Virtual structure s=al or s=ol generates
3512 and-list and or-list respectively instead of phrase search.
3516 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3517 log_mask_str. This was done to avoid name conflicts with other libraries
3518 (such as other PHP extensions).
3520 Added raw OID member for preferred record syntax (request_format_raw)
3521 and returned record syntax (output_format_raw) for backend fetch method.
3523 Config file yaz-config now accepts options so that it returns specific
3524 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3526 Shared library support for UNIX using GNU libtool.
3528 * Modified backend interface. Request/Response struct's replaced by
3529 one read/write C struct. For example bend_fetchrequest and
3530 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3531 Every handler - even search has to be registered in bend_init
3532 handler. This means that the YAZ library no longer refers to
3533 external functions and it makes it possible to make the whole
3534 thing a single DLL/SO.
3536 Added Segment handler for backend server.
3538 Added Zmbol/Zebra administrative functions to YAZ client.
3540 Threaded frontend server on UNIX (when POSIX Threads are available).
3541 Starting the server with option -T enables multi-threading.
3545 Added configure option --enable-comp/disable-comp to control use
3546 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3547 located in sub directory asn.
3549 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3550 in ${exec_prefix}/bin along with the other programs yaz-client and
3553 GNU automake used to maintain makefiles.
3555 Added several OID's.
3557 Changed retrieval module so that we can load records with no abstract
3558 syntax defined. Tagpaths in these records are fully composed of string
3561 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3565 On UNIX, the generated makefile now supports a proper 'make install'.
3566 The prefix can be set via GNU configure to set the install location
3567 (default is /usr/local).
3569 * YAZ programs client and ztest were renamed to yaz-client and
3570 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3571 locations, such as /usr/bin,/usr/local/bin,etc.
3573 * YAZ Header files were moved from include to include/yaz. YAZ Header
3574 files are referred to as include <yaz/log.h> rather than <log.h>.
3575 The YAZ include path (-I ..) is therefore the same as before. Programmers
3576 should update their #include statements or use -Ipath/include/yaz
3577 instead. The main motivation for doing this change is that YAZ header files
3578 can be installed in "standard" locations /usr/include,/usr/local/include
3579 without introducing conflicts, since ALL YAZ header files are stored
3580 in subdirectory yaz (under /usr/include for example).
3582 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3583 rather than project/workspace files. We switched because project files
3584 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3587 Changed name of logging function, logf, to yaz_log, to prevent name
3588 clash with some math-log functions. The YAZ header log.h defines logf
3589 to yaz_log (#define) so there should be no incompatibilities by this
3592 Added bend_start/bend_stop handlers for server. These handler are
3593 called on start/stop of server. For windows they are called whenever
3594 a service is started/stopped.
3596 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3597 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3598 in util/yc.tcl. The auto-generated C code structures are, in a few
3599 cases, incompatible with the old decoders. There are differences in the
3600 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3601 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3602 The preprocessor variable ASN_COMPILED is defined when the compiled
3603 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3604 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3605 wish to use the old encoders/decoders you can specify --disable-yc
3608 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3609 version so that it supports both new - and old version of DB Update
3611 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3612 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3613 change. The name parameter can be set to 0 in which no name is specified
3614 for the construction. The macros odr_implicit and odr_explicit sets name
3615 parameter to zero for the construction involved. New macros
3616 odr_implicit_tag and odr_explicit_tag are similar to the others,
3617 except that a name parameter is added. For programmers' that don't use
3618 ODR they probably only need to change the call to z_APDU and z_External.
3620 Added access control facility by interfacing the TCP wrapper library.
3621 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3622 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3623 name of the daemon and enables the access control as specified in
3624 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3626 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3627 den Dool <H.M.vdnDool@kub.nl>.
3629 Added reference ID parameter to most functions in server API - refer
3630 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3632 Changed name of ccl library to libccl.a (was ccl.a).
3634 Fixed bug in decoder for Explain (Category TargetInfo).
3636 Added support for GNU readline in client. Thanks to Jacob Poulsen
3637 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3639 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3640 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3641 IMPLEMENTATION! This change was made to the development version before
3642 the ZIG decided to retract the amendment. If any users MUST be
3643 compatible with the original Update definition, PLEASE CONTACT US, and
3644 we will include a separate definition corresponding to the old Update
3645 ES. Note that because of the change to the ASN.1 of the
3646 TaskPackageRecordStructure we cannot define a single structure that
3647 will support both versions.
3649 * Added const modifier to buffer parameter for some ODR/BER encoding
3650 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3651 completeWAIS, odr_dumpBER.
3653 Fixed bug in client.c which caused a crash when a scanResponse didn't
3654 contain positionOfTerm.
3656 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3657 * will cause an error in a client if a non-YAZ target sends both a
3658 * list of Scan entries and non-surrogate diagnostics.
3660 Retrieval module enhancements. Tag sets may be typed in the reference
3661 to it. From the .abs-file the "tagset" directive takes a third optional
3662 integer type for the tag set referenced. From a .tag-file the "include"
3663 directive takes a third optional type as well. The old "type" directive
3664 in the tag set itself is still recognized but acts as the default type
3667 Backend interface change. Individual Scan terms returned from bend_scan
3668 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3669 in include/backend.h.
3671 Retrieval module enhancements. Multiple tag sets and attribute sets may
3672 be specified in abstract syntax specs. Revised the error/warning for
3673 logging messages reported by the retrieval module when reading the
3676 Object Identifier system (oid_..) changed. The API is backwards
3677 compatible but the oid-routines now allocates new OID's when needed.
3678 Raw OID's may be specified in oid_getvalbyname.
3680 YAZ now uses GNU configure to generate Makefile(s).
3682 * Minor changes in some of the member names of DeleteResultSetRequest and
3683 DeleteResultSetResponse. See include/proto.h.
3685 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3686 and added member 'languages' in TargetInfo (which was missing).
3688 Changed the way attribute sets are handled in the retrieval
3689 module. These are now cached, just like the abstract syntaxes
3692 Changed YAZ so that it links with compiled ASN.1.
3694 Added Explain-schema definitions and mapping routines. The following
3695 Explain categories have been implemented: AttributeDetails,
3696 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3698 Fixed minor bug in Windows version of Server Library.
3700 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3702 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3704 Added EXTERNAL: UNIverse Resource Report (non-standard).
3706 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3707 ENUMERATED and SET OF.
3709 * Added 'const' to some of the char pointer arguments for the
3710 functions, data1_read_node, data1_getelementbytagname,
3711 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3714 Fixed bug in data1_insert_taggeddata - the last_child member of
3715 parent wasn't initialised.
3717 * Changed data1_read_record and data1_read_node so that the supplied
3718 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3719 doesn't refer to any parts of the "SGML"-buffer.
3721 Fixed bug in server library (Windows version of statserv_remove).
3723 * Changed code so that it compiles as C++. The type definition
3724 of Odr_fun which is a member of Odr_arm was changed. The result is,
3725 that an explicit typecast is needed for the fun pointer when
3726 using Odr_arm - as in:
3727 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3729 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3731 Implemented the new structured date and time definition as approved
3732 by the ZIG. Added schemaId element to the specificTag in Espec-1
3733 (also approved at the last ZIG). Thanks to RVDM.
3735 Added some Object identifiers (RVDM).
3737 Changed the Update Extended Service (RVDM).
3739 Added command "refid" to client which specifies referenceId for
3740 the following requests.
3742 Implemented extended service handling for server. See ztest.c
3743 for an example as well as backend.h. New handlers are registerd
3744 in the Init handler.
3746 * Changed interface for sort in server.
3748 Added new members to statserv_options_block. It allows a server
3749 to read options from another source than just the command line. Thanks
3750 to Charles Woodfield.
3752 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3753 renamed to zboolean. Some C++ compilers complained about the name.
3755 Minor changes to gils.abs. Added index 's' (sort) on title
3756 and date/time-last-modified.
3758 --- 1.4pl2 1998/1/30
3760 Fixed bug in server library regarding inetd mode (-i). This bug
3761 was introduced by release 1.4.
3763 --- 1.4pl1 1998/1/29
3765 Added sort facility in client and backend server interface.
3767 Fixed problem with dependencies in Makefile(s).
3769 Fixed bugs for encoders/decoders of extended services and
3772 Implemented sub-tree feature for schemas. Sub-trees are
3773 referenced in *.abs-files. See explain.abs for an example
3774 of the use of this feature.
3776 Modified bib1.att; local attributes for ANY didn't include
3777 ANY itself (only affects use of the retrieval module).
3779 Fixed bug in plain SGML reader in function data1_read_node:
3780 tags with prefix "var" was incorrectly interpreted as variants.
3782 Added feature "sub-schemas" to enable references to - and definitions
3783 of - group of elements.
3785 * Removed member parent from type data1_element (in data1.h).
3787 Implemented function odr_nullval() that returns the value of
3790 * Removed member num_children from data1_node (in data1.h).
3792 Made NT service interface part of the server library. The
3793 function statserv_main uses the NT service when required and
3794 calls the statserv_start / statserv_close routines.
3796 Routine zget_SearchRequest and zget_PresentRequest fills
3797 resultSetName/Id member with "default" instead of "Default".
3799 Fixed memory leak in server. Request queue member wasn't freed.
3801 Fixed nmem_exit so that memory is freed.
3805 Revised the CCL parser utility to be thread safe.
3807 Added function, oid_ent_to_oid, to replace the function
3808 oid_getoidbyent, which is not thread safe.
3810 * Added nmem_init and nmem_exit to initialize and release
3811 NMEM resources. Function nmem_init should be called once in the
3812 initial thread before NMEM/ODR is used. statserv.c and client.c
3813 have been changed accordingly. The change was necessary to make
3814 NMEM thread safe. The NMEM memory pool is shared amongst threads
3815 in a process. Unix-based applications will still work fine without
3818 Added NT Services interface for the the Z39.50 (statserv) Server.
3819 Refer to the ztest.c source on the usage.
3821 Windows 95/NT port using MSVC5.0. Project files are included in the
3824 * Defined new 'global' handle for the retrieval (data1) system. The
3825 new handled, data1_handle, describes the state of the data1 system.
3826 This handle is passed as first argument to virtually all
3827 data1 related routines. The functions data1_create and data1_destroy
3828 creates and destroys a data1 handle respectively.
3830 Added ODR encode stream member to all backend request structures
3831 init, search, scan etc. This stream should be used to allocate all
3832 memory used for the response when thread safe operation is needed.
3834 Changed the comstack utility, cs_addstr, to be thread safe. The
3835 returned hostname string returned by the function is now part the
3838 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3839 function. The cs_straddr takes a COMSTACK handle as argument, so this
3840 function must be used after cs_create and before bind/connect.
3841 This function is thread safe.
3843 Moved test server to 'ztest' directory - generic server code still
3844 in 'server' directory.
3846 Made prefix query (pquery.c) utility thread safe.
3848 Added new function modifier YAZ_EXPORT to 'export' public DLL
3849 functions when using windows (see include/yconfig.h).
3851 Added definitions to the OID database (util/oid.c) (RVDM).
3853 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3855 Added call to ccl_rpn_delete in client program.
3857 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3858 release of RPN structure.
3860 Added support for C++, headers uses extern "C" for public definitions.
3861 With input from RVDM.
3863 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3864 Thanks to Ronald van der Meer (RVDM).
3866 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3868 Added support for private extensions to the OID database
3869 (oid_setprivateoids()). Thanks to RVDM.
3871 Added optional, physical ANY (key replication)
3873 Fixed null-reference problem in GRS-1 output filter.
3875 Proximity operator added to Prefix Query Format (PQF).
3877 In test client command "base" accepts multiple databases.
3879 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3883 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3885 Smallish bug-fixes in the new encoders/decoders (explain).
3887 Bug fixed in DeleteRequest.
3889 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3891 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3893 Added SOIF syntax (using private OID for now) to retrieval module and client.
3895 Added Update extended service.
3897 Added SearchResult-1 additional info structure.
3899 Added optional CCL (ISO8777) interpreter as separate module. Available
3902 --- 1.2 1996/6/10 (1st anniversary release)
3904 Added Summary record syntax. Lightly tested.
3906 Added OPAC record syntax. Untested.
3908 Added ResourceReport service encoders/decoders. Untested.
3910 Fixed bug in z_Unit - wrong tagging on unitSystem.
3912 Fixed bug in the DiagRecs decoder.
3914 Added options for max PDU size and session timeout to frontend-server.
3916 Added documentation of query-language parsers and other supporting utilities.
3918 [frontend-server] Added Attribute set to the bend_scanrequest API.
3920 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3921 surrogate diagnostics were generated.
3923 [retrieval] Allow multiple local values for attribute.
3925 [retrieval] Allow multiple attributes per element in .abs files. index type.
3927 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3929 --- 1.1pl2 1996/4/10
3931 Minor changes, mostly specific to Zebra's requirements (retrieval)
3935 Repaired bug in frontend server when running multiple listening
3936 endpoints in dynamic mode.
3938 z_External() now won't break if a known, ASN.1 value comes encapsulated
3939 in an octet-string. The value will pass through unmodified in an Odr_oct.
3941 Added a bit of code to the demo client to decode & display
3942 ASN.1-structured records represented in the octet-aligned branch of
3943 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3945 Added z_ext_getentbyref() to the ASN module. Doc updated.
3947 * Completed the SCAN definition in the ASN module. This may break SCAN
3948 code based on older YAZ-versions at compile-time. The fix is easy -
3951 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3952 under the SCAN definition. Remember to initialize this, server-people.
3954 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3955 that this does not extend to ODR and ASN.
3957 Comstack allows insertion of established socket (primarily for
3958 inetd-operation of servers). Doc updated.
3960 Front-end server can now start from the inetd in TCP mode. Doc
3963 --- 1.0pl4 1996/1/24
3967 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3968 the rank and record number.
3970 Adjustments to the frontend server.
3972 Fixed diagnostic BER dumper. It ignored the file argument.
3976 Various changes to retrieval module.
3978 Changed the union discriminators of the protocol files from enums to
3979 ints paired with #defines.
3981 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3984 *Changed operator in the RPN structure to 'roperator', again to avoid a
3987 Fixed problems in Explain decoders/encoders.
3989 --- 1.0pl2 1995/12/6
3991 Memory bug in log module fixed.
3993 --- 1.0pl1 1995/12/5
3995 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3997 Bug in Explain DatabaseInfo module fixed.
3999 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4003 The shift to v1.0 signals that we now consider the *core* functionality
4004 of YAZ reasonably stable (the core being more or less equivalent to
4005 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4006 tested (Explain not at all - though that will happen soonish).
4008 Minor changes to code to support Windows port.
4010 Various minor changes after we're getting to use GRS-1 & co. more.
4012 Added Espec-1 format.
4014 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4015 of the protocol and it cannot be selected when encoding (maps into 'string'
4016 when decoding). Needed to talk to some servers.
4018 Demo client can request simple element set names.
4020 Added Diagnostic Format encoders/decoders.
4022 Added simple Close handling to frontend server (no hooks for resource
4023 reporting yet), and demonstration client.
4025 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4027 --- 1.0b3 1995/08/24
4029 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4030 handled incorrectly when records were requested in the searchResponse. This
4031 will only affect you if you use the frontend-server.
4033 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4034 Test-client will ask for and print GRS1. Ztest will return dummy records
4037 Added Explain encoders/decoders to the service-level API. Untested.
4039 Added Extended Services: Item Order encoders and decoders to the Service-
4040 level API. Untested. We could use a recent copy of the pertinent bits
4041 of the ILL protocol to add those bits.
4043 Added diagnostic format 1 encoders/decoders to the service-level API.
4046 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4047 odr_cons.c, which causes a more correct output.
4049 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4050 was always set to 0 when no records were requested in the searchRequest.
4052 * Added better external-handling. This shouldn't harm old code that
4053 *encodes* externals. It can break code that looks for a
4054 'single-ASN1-type' representation, since those types that are known
4055 are now decoded immediately. Look at the SUTRS sample code in
4056 seshigh.c and client.c. Documentation updated.
4058 Handling of structured records in bend_fetchresponse. Length -1 marks
4059 structured record, type is deduced from format field.
4061 --- 1.0b2 1995/06/27
4062 Fairly quick maintenance release to add SUTRS support.
4064 Fixed handling of SUTRS records in the demonstration client.
4066 * Added format field to the bend_fetchrequest and bend_fetchresponce
4067 structures of the backend API (frontend server). When the record is
4068 returned, the value of the format field is mapped to an OID. The
4069 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4070 of the record. The special value VAL_NONE in the bend_request means
4071 that no specific format was requested by the client. Documentation
4072 updated accordingly. Test server (ztest) will return a fixed dummy
4073 SUTRS record if your client requests SUTRS.
4075 Documentation updated accordingly.
4077 You can now set external libraries and RANLIB support in the top-level
4081 First public release.
