3 clone_z_type: fix leak; occurred for enc failures.
5 Add libyaz.la to yaz-icu's LDADD list. yaz-icu uses libyaz.la symbols - not
6 only libyaz_icu.la. This should fix Debian bug:
7 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=556768
8 A similar problem was present for yaz-ztest, IDs bugzilla #3036.
12 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
13 bug was introduced in 3.0.51.
17 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
19 tcpip comstack: fix leak for getaddrinfo.
21 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
22 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
23 Decoding of SRU "path" database is performed by private function
24 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
25 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
27 yaz-client: honor base command for SRU. Change when database setting
28 is applied for SRU and ensure it is kept when a connection is reset.
29 Change also the way errors are displayed or SRU (decoding of packages).
33 Add support for extra request / response data for SRU codecs and GFS.
34 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
35 for extra data response buffer and length. For the GFS, both request
36 and response data (XML) is carried in extra_args and extra_response_data
37 for the search handler. Patch by Ko van der Sloot.
39 ZOOM: For queries that cannot be converted to the specified rpnCharset,
40 ZOOM now returns a diagnostic on the client-side ('invalid query' /
41 10010). This fixes bug #2113.
43 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
44 cmdfile included a 'quit' command that would result in a memory violation.
48 Make a number of functions defined in xmlquery.c static. These have
49 never been declared in a public header file (yaz/xmlquery.h) and was
50 made public by mistake.
52 Improve speed of character conversions (iconv utilities). This makes
53 conversions from MARC-8 faster.
55 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
56 unless type desired is "raw". This will prevent type "xml" from
57 returning ISO2709 .. Which obviously can not be XML parsed.
59 Fix memory leak in ZOOM that would occur if option apdulog was used
60 on a re-used connection.
62 Frontend server logs HTTP requests.
64 Frontend server now sends Z39.50 close when it times out (sesssion has
65 been idle for too long). Versions 2.0.30 and earlier also sent close.
66 But due to a mistake this was disabled in all versions after that, i.e.
67 the server would just close the socket immediately.
69 yaz-client emits a better message when receiving an unrecognised
72 Skip zero-length subfields when decoding ISO2709. This rare case happens
73 if a record has two FS characters in a sequence. Without this patch
74 there would be a reference beyond char array in using_code_len fragments
77 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
81 The show command offered by the zoomsh command now takes a 3d optional
82 parameter type which is what is passed to ZOOM_record. If the type
83 argument is omitted, "render" is used.
85 RPN to CQL conv may use USE string attributes (bug #2978).
87 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
91 Function yaz_xml2query allows a diagnostic element in the PQF XML
92 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
93 code and additional info respectively.
95 The BER BOOLEAN is now the integral type Odr_bool which still happens
96 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
97 typedef'd to Odr_int. This is still an integral 'int', but it may be
98 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
99 ASN-1 compiler as well as programs has been updated to use the new types.
101 --- 3.0.46 2009/06/08
103 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
104 only the bibliographic record was rendered. For type=opac, an OPAC
105 record is only returned if it is present.
107 iconv: small fix for encoding of advancegreek.
109 yaz-client: avoid double display of SRU/SRW records (bug #2798).
111 yaz-client: option auto_reconnect=on really reconnects.
113 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
115 server: avoid null ptr ref for for yaz_poll errors.
117 build: fix RPM build for RHEL 5.3.
119 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
121 --- 3.0.45 2009/03/31
123 Fixed bug #2709: TCP connect returns Invalid argument.
125 Fixed compilation for mingw.
127 Honor charset for raw records (ZOOM_record_get).
129 Fixed use of errno for threaded mode that was seen on Solaris 10.
131 Fixed argument passing with blanks in value for Windows Service.
133 Disable YAZ' own log rotate by default (no 1 GB limit).
134 The variable l_max_size which specifies the log file limit is set to 0
135 (DISABLED): This is due to the fact that YAZ is most often deployed using
136 logrotate. Also YAZ can not perform log rotate because of unsufficient
137 permissions (setuid).
139 --- 3.0.44 2009/02/17
141 List supported encodings in man page for yaz-iconv.
143 Fixed missing SSL libs for --libs output
145 Re-established OID record syntax application-xml. Nobody should use it
146 but we don't want to change soname because of this symbol being absent.
148 --- 3.0.42 2009/02/02
150 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
152 Added member named_result_sets for init handler struct for the GFS. This
153 allows a server to disable named result sets.
155 Removed OID record syntax application-xml.
157 Added support for rule-based transliterator for ICU wrapper of YAZ.
159 Fixed bug #1902: yaz-icu XML output.
161 Make YAZ checks Emacs friendly.
163 BITSTRING value shows value. Bug #2346.
165 ISO2709 decoding: skip control characters from indicator data.
167 Omit sort key by default in yaz-icu's output.
169 Allow combined single char options (again) for YAZ' options function.
171 Utility yaz-marcdump got option to display YAZ version (-V).
173 Allow YAZ to use ICU 3.4.
175 Added new ICU test case which illustrates removal of diacritics.
177 --- 3.0.41 2008/12/29
179 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
181 --- 3.0.40 2008/12/29
183 For configure, using option --without-xml2 also disables Libxslt/Libexslt
186 Fixed bug #2352: yaz-marcdump crashes for certain record.
188 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
190 Added support for Danmarc2 to UTF-8 conversion.
192 Added support for ISO5426 to UTF-8 conversion.
194 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
195 implementation version.
197 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
199 --- 3.0.38 2008/11/10
201 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
202 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
204 ZOOM C now interprets databaseName option for ZOOM connection as path
207 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
209 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
211 Dummy Libxml2 types no longer defined in headers of YAZ'.
213 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
216 --- 3.0.36 2008/09/26
218 Various ODR chapter fixes.
220 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
222 Added missing source for Windows compilation, mutex.c.
224 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
226 For SRU connections in ZOOM all records up to "count" are now fetched.
228 Fixed crash in generic frontend server (and yaz-ztest) which occurred
229 in Windows due to bad error handling for Libxml2.
231 Added facility for sending arbitrary records (ASN.1 any) using
232 ZOOM C's Extended service update. Patch by Sam Reynolds.
234 New options for ZOOM C's connection, logapdu which makes ZOOM log
237 --- 3.0.34 2008/06/18
239 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
241 --- 3.0.32 2008/06/12
243 Fixed memory violation that could occur when decoding UTF-8. This bug
244 was only present in 3.0.30 of YAZ.
246 --- 3.0.30 2008/06/06
248 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
249 GNU TLS is used by default (if found).
251 yaz-ztest returns OPAC records if a client asks for OPAC.
253 Improved speed of MARC-8 encoding.
255 Added support for lossy and loss-less MARC-8 encoding.
257 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
259 Added new Windows Service wrapper (sc).
261 yaz-client's itemorder command may now send a file.
263 Fixed yaz-marcdump to allow the use of NS prefix for record element.
265 Added new function yaz_log_xml_errors.
267 Allow (but warn) unknown XML attributes in MARCXML parsing.
269 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
271 The UTF-8 to MARC-8 conversion now uses a different set of characters
272 for Greek symbols. Bug #2120.
274 --- 3.0.26 2008/02/21
276 Added yaz_daemon (daemon.h).
278 Fixed bug #2068: pkg-config trouble
280 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
282 --- 3.0.24 2008/01/28
284 Document --with-xml2 option.
286 Added OPAC XML XSD (etc/opacxml.xsd).
288 Allow glob mask for name attribute in retrieval element for the
289 generic frontend server's retrieval facility.
291 Changed yaz_poll_poll to return yaz_poll_except for all returned events
292 except POLLIN/POLLOUT.
294 Fixed error handling in cs_listen. Bug #2037.
296 --- 3.0.22 2008/01/20
298 Fixed version in yaz/yaz-version.h.
300 Fixed bug #2027: Crash when closing connection.
302 Changed configure so that ICU support is only enabled if only ICU
303 and Libxml2 is available (because the ICU chain is XML based).
305 --- 3.0.20 2008/01/15
307 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
308 is built. Only this DLL depends on the ICU runtime.
310 yaz-ziffy is no longer part of YAZ. It is distributed separately by
311 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
313 Changed license of CCL module to 'Revised BSD'. After consultation with
314 remaining members of the original EUROPAGATE consortium, we are re-issuing
315 the CCL module without a separate license. The software was developed by
316 Index Data as part of a research project. The special license was included
317 to help feed usage information back to the project consortium to support
318 project evaluation. At this time, the project consortium has long-since
319 disbanded, and the majority of the original principals have retired. At the
320 same time, we have significantly modified the software during the following
321 years, to the point where very practically no original code remains. To
322 simplify re-use of the software, we have contacted those members of the
323 consortium who could be reached, and agreed to re-issue the module as a
324 proper part of the YAZ package.
326 Tcl scripts uses /usr/bin/tclsh as preferred shell.
328 CQL closer to being version 1.2 compliant. CQL also allows free-form
329 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
332 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
333 bug could make Extended services handling crash in the ZOOM layer. This
334 bug was only present in YAZ 3.0.18.
336 --- 3.0.18 2007/12/19
338 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
341 yaz-marcdump reads and writes collection wrapped records.
343 Handle OPAC for record conversion module.
345 Fixes for ICU wrapper.
347 Allow ICU libs to be controlled with --with-icu .
349 --- 3.0.16 2007/11/12
351 Added yaz_poll which is a wrapper for select/poll. When poll is available
352 and non-buggy, it is used, by yaz_poll . This allows more than 1024
353 sockets to be in use.
355 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
356 functionality through an XML based configuration (ICU chain). This system
357 is useful for search facilities such as Pazpar2 and Zebra that needs to
358 perform tokenization of indexed material. The ICU code in a separate
359 library libyaz3_icu.a.
361 Added HTTP tunnel facility for COMSTACK, bug #1752.
362 This is a facility that allows a Web proxy, such as squid, to tunnel
363 Z39.50 traffic. This facility is "transparent" to must applications
364 using YAZ. It's enabled by using pseudo transport connect: followed by
365 the proxy address, followed by command, then follwed by he regular
366 "virtual" addresss. For example,
367 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
369 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
371 --- 3.0.14 2007/09/21
373 Fixed bad memory reference in ZOOM_record - cuased by member not being
374 initialized. This was a problem only in YAZ 3.0.12.
376 Fixed bug in conversion from MARC to XML: Non-XML characters in control
377 fields were not removed.
379 Changed the way C code is generated from codetables.xml. Made a MARC-8
380 conversion trie for each characterSet section rather than codeTable.
381 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
382 of codetables.xml from Larry Dixson, LOC. Bug #1464.
384 --- 3.0.12 2007/09/12
386 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
387 from ZOOM_record_error).
389 ZOOM C function ZOOM_record_get returns record schema for type="schema".
391 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
393 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
395 Better SRW-to-Bib-1 diagnostic mapping.
397 ZOOM C and yaz-client announces SRU version 1.2 by default.
399 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
402 Fixed in yaz_sru_decode to allow other version than 1.1.
404 --- 3.0.10 2007/08/22
406 Added support for SRU scan for ZOOM.
408 Added support for the use of the older versions or Extended Service
409 Update in ZOOM. To faciliate this, an option "updateVersion" may be
410 set to the version , 1=first, 2=second, 3=third. The third version is
411 what ZOOM C has used so far. And that, obviously, is the default.
413 Added support for CCL queries in Z39.50 queries sent to the GFS (and
414 therefore in Zebra and in SimpleServer-based applications). The new
415 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
416 qualifier file used to transform incoming CCL queries into Type-1 RPN,
417 which is passed into the back-end search callback function.
419 Added support for HTTP Basic authentication in clients: the SRU/W
420 codec encodes the username/password elements of the PDU structure
421 appropriately, and these may be set using the "user" and "password"
422 options in ZOOM-C applications (the same options that are used for
423 Z39.50 authentication).
427 Fixed bug #1208: SSL appears to be broken in ZOOM.
429 Fixed bug #1206: Libxml2 include path weirdness.
431 Added oid_name_to_dotstring.
433 Allow elementSetName to be specified for ZOOM C record update.
435 Allow waitAction to be specified for ZOOM C based for Extended Services.
437 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
438 syntax OID. Bug introduced in YAZ 3 series.
440 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
444 Fixed bug #1157: yaz-client does not read .yazclientrc from current
445 directory. yaz-client now reads commands from file given by option -f
446 if specified; then tries to read .yazclientrc in current directory.
447 Failing that, it reads .yazclientrc from user's home directory.
449 Added support for correlationInfo Note and ID for Record Update via
452 Added yaz-client command querycharset which specifies character set for
453 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
454 (termListAndStartPoint).
456 Charset ISO5428:1984 is an alias for ISO5428-1984.
458 Implemented a way to perform scan in a result set using Z39.50. This
459 is achieved by attaching the result set name in the characterInfo
460 (type InternationalString) of OtherInformation in the Scan Request PDU.
461 The result set is identified in the otherinformation by the new OID:
462 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
463 This allows for scan in result set and faceted search . Zebra did some
464 of this in the APT term using attribute type 8 and value being result
465 set. Using the OtherInformation approach for this is cleaner and easier
466 to work with in proxies and the like. This facility can be used in
467 yaz-client using new command setscan which takes a result set as first
468 argument, start position (APT) as second.
470 Changed decoding of SRU XML packed records to deal with servers that
471 have recordData with XML data with multiple root nodes. Also make
472 comparison for recordPacking case insensitive. Again, one server
473 returns "XML" where others return "xml".
475 For SRU responses allow Content-Type application/xml as well as text/xml.
479 Fixed bug in character set conversion of BER strings. Bug introduced
484 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
486 For OID class, use oid_class consistently.
488 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
491 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
492 character set for bibliographic information interchange". By Giannis Kosmas.
494 Added documentation on new OID API.
498 Changes to generic frontend server interface: added new member
499 'query_charset' for bend_initrequest structure. A backend init handler
500 should set this member to its native character set for query terms.
501 When defined, the frontend server logic will announce this character set
502 to a client if the negotiationModel bit is set by the client. All server
503 implementors are encouraged to specify this. If a backend server does not
504 specify this a warning is issued using yaz_log(YLOG_WARN,..).
506 Added CCL utility to remove terms (stop words) from resulting RPN
507 tree. This is handled by functions with prefix ccl_stop_words_ .
509 New ZOOM C option, "rpnCharset", which allows client-side conversion of
510 terms in RPN queries.
512 Clean-up the CCL API. Moved some internal structures from ccl.h to
513 private header cclp.h. Changed ccl_parser_create so that a Bibset must
514 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
515 This is replaced by ccl_parser_find_str which takes a string instead.
517 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
518 libyaz.la is the core of YAZ except the generic frontend server and
519 does not depend on POSIX threads anymore. libyaz_server.la is the
520 generic frontend server facilities and uses POSIX thread functionality
521 if available. The libyaz.la no longer depends on POSIX threads because
522 the number of global structures is limited. NMEM no longer re-uses blocks
523 between threads ; it simply free's memory immediately but allocates in
524 "large" chunks as usual. We don't expect any performance penalties
525 because of this. The yaz_log system is still using a global log_level so
526 caution must be taken when modifying it with yaz_log_init_.. +
527 yaz_log_mask_str. This, however, should not cause any trouble because
528 these functions are called during initialization of application code
529 anyway. `yaz-config --libs server` returns libs for server applications;
530 `yaz-config --libs` returns libs for non-server applications.
532 New OID database - with public definitions in oid_db.h. Removed old OID
533 database including the head oid.h and definitions such as enum oid_value
534 and struct oident. The new OID database uses the same string names as
535 before but the 'protocol' is gone. There are now only two representations
536 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
537 converts from string to OID; functions with prefix yaz_oid_to_string
538 converts the other way.
540 Change to emit_term() in CQL-to-PQF query translation: when a term has
541 the /regexp relation modifier, do not process it for leading and
542 trailing "^" and "*", which have quite different meanings in regular
545 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
546 write handlers no longer carries a 'last' parameter. This will make
547 yaz_iconv flush "less" characters. A flush is performed by call to
548 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
550 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
551 removed, because function yaz_query_to_wrbuf does the same.
553 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
554 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
556 Deprecated MARC utility functions removed.
558 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
561 Branch split: YAZ_2_1_55_branch
563 --- 2.1.54 2007/03/16
565 Fix to ZOOM-C so that transparent reconnection is properly handled on
566 connections that are in asynchronous mode.
568 Fixed compilation on OpenBSD 4.0.
570 Large strings in GRS-1 records are now properly displayed in yaz-client.
572 Added character conversion support for "advancegreek"; based on patch from
575 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
576 sequence is met. Before the error was not set so it would be unknown.
578 Adjust yaz-marcdump MARC reader so that it skips until record separator
581 --- 2.1.52 2007/03/07
583 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
584 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
585 fd_set structure used as a bitmask for the FDs to be selected on.
587 Using ACX_PTHREAD macro to check for POSIX threads.
589 Fixed have-vsnprintf check.
591 --- 2.1.50 2007/02/23
593 Fixes for configure on BSD. Bug #900.
595 Added snprintf/vsnprintf wrappers for systems that don't have
596 limits (heavens forbid).
598 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
599 created before all previous tasks were completed and removed from the
600 task queue, the new task could be removed by a mistake.
602 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
604 Implemented pass-through CQL-to-PQF conversions. Bug #861.
606 Fixed bug #832: Problem with MARC/charset in yaz-client.
608 Fixed bug #668: save command line history for yaz-client.
610 Fixed bug #830: pkg-config support.
612 --- 2.1.48 2007/01/23
614 Extended ZOOM result set options with two options that may be read by
615 a client: resultSetStatus and presentStatus with values as specified for
617 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
619 Fixed bug #827: Using SSL fails on Debian etch.
621 Fixed bug #826: Weird looking chars for set of MARC records.
623 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
624 that is treated as an ItemOrder with itemRequest being an XML document
625 external. The value of "doc" is the content.
627 Extended the GFS search facility. New member of bend_search_rr
628 'estimated_hit_count' signals that hits is known to be an estmate
629 (higher or lower than real hit count). New member 'partial_resultset'
630 signals that the search was partial (hit count is lower or equal than
631 real hit count). For Z39.50, the information is stored in resultSetStatus
632 member of SearchResponse APDU. For SRU, the information is signalled
633 via SRU diagnostic 59: "Result set created with valid partial results
636 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
638 --- 2.1.46 2007/01/13
640 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
642 Added ZOOM_connection_peek_event.
644 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
645 the following new functions:
646 ZOOM_event_nonblock, ZOOM_connection_process,
647 ZOOM_connection_get_{socket,mask,timeout},
648 ZOOM_connection_fire_event_{timeout,socket}.
649 The existing blocking event handler, ZOOM_event, is a wrapper for the
650 + blocking ZOOM_event_sys_{poll,select}.
652 Implemented function ccl_xml_config which parses XML version of CCL
653 configuration (bug #798).
655 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
657 Added timings utility (yaz/timing.h)
659 --- 2.1.44 2007/01/03
661 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
664 Fixed bug #779: Rotation of apdu.log fails.
666 Fixed for character set conversions:
667 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
668 Honor G1 set in MARC-8 decoding.
670 --- 2.1.42 2006/12/17
672 Fixed bug #775: char conversion does not handle Alternative UTF-8
675 Implemented function yaz_marc_read_line which parses MARC line format
676 records. There is a wealth of formats out there. So far, this function
677 reads line records produced by yaz_marc_write_line.
679 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
680 more generic and easier to remember(!) options: -i format and -o format
681 which specifies input format and output format respectively - where
682 format is one of "marc", "marcxml", "line", "marcxchange".
684 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
685 does not print anything except warnings for records.
687 For yaz-marcdump, added support for MARC split into files (-s) with a given
690 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
691 spec, at http://www.loc.gov/standards/sru/record-update/
692 This has changed the binary layout of the following structs:
693 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
694 bend_update_rr . Patch by Ko van der Sloot.
696 Added GFS utility function bend_assoc_is_alive which returns 1 if
697 association is still alive (client is connected); 0 otherwise (client
698 closed connection). This allows busy servers to stop working for
701 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
702 been a separate piece of software. This version of ziffy has been modified
703 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
705 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
707 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
708 Client code may now interrogate options such as "init_opt_sort" to
709 find out whether the server claims to support various options.
711 --- 2.1.40 2006/11/27
713 Added utilities yaz_{set,get}_esn to set/get element set name from
716 Removed the build of libyazthread.la. The libyaz.so is the threaded version
717 of YAZ and has been so since YAZ 2.1.10.
719 Implemented ZOOM_record_error which returns error information for
720 record (surrogate diagnostic).
722 --- 2.1.38 2006/10/31
724 Updates for SRU Update by Ko van der Sloot:
725 1. Changed name from "operation" to "action"
726 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
727 versions in the code, marked as 'backward compatible'.
728 3. Added diagnostics for SRU Update.
730 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
732 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
734 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
736 For GFS, fixed problem with SRU diagnostic 'First record position out of
737 range' being issued for 0 hits.
739 zoomtst10 part of Windows Build.
741 --- 2.1.36 2006/10/13
743 Implemented yaz_filepath_comp which splits a path into file path
744 components (required by Zebra 2.0.3+).
746 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
747 BSD inspired license until now so this should not have any real impact on
748 anybody. See http://www.opensource.org/licenses/bsd-license.php
750 Fixed bug #687: Missing log lines.
752 Fixed bug #678: CQL to PQF translation does not preserve double-quote
755 Fixed bug #689: SRU diagnostics to be added.
757 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
758 whether a connection is idle (no more work do do).
760 --- 2.1.34 2006/10/04
762 Change type of optval from long to int for invocation of setsockopt with
763 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
765 Added support for specifying the max log file size for the Generic
766 Frontend Server. The size is given with option -r.
768 --- 2.1.32 2006/09/21
770 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
772 --- 2.1.30 2006/09/17
774 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
777 Fixed bug in Generic Frontend Server that could cause a server to stop
778 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
780 For the generic frontend server, the maximum record size is used as maximum
781 size of incoming packages (SRU + Z39.50). The value until was previously
782 only used in Z39.50 Init negotiation and, later, in a session controlled
783 sizes of records returned. This is controlled using -k option. It can be
784 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
786 --- 2.1.28 2006/09/04
788 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
791 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
793 New option for yaz-marcdump -lpos=value which allows setting a portion
794 of MARC header to a certain value.
796 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
798 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
799 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
801 --- 2.1.26 2006/08/15
803 Fixed problem with SRU mode type (soap, get, post) for yaz-client
806 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
808 --- 2.1.24 2006/08/08
810 Fixed MARC ISO2709 encoding routines to deal with character set
813 Minor changes to GFS logging. Database included in search request log
816 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
817 cached/multiple records.
819 Shared libraries are built by default on Unix+configure.
821 Changed cql2pqf transformation to use a different evaluation order. The
822 new order is: always, relation, structure, position, truncation, index
823 and relationModifier. Old order was: always, relation, relationModifier,
824 structure, index, position, truncation. Note that the the latter ones
825 override former ones for identical attributes.. The new scheme means that
826 it is possible to override any existing attribute with a relationModifier.
827 And also that it is possible to override everything for the index rule
828 (except the ones listed in relationModifier). No order is perfect but this
829 one, we believe, covers more real cases.. The "always" should have been
830 called "default", since the attributes there can be overridden with all
833 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
834 compilation phase, but also for yaz-config --cflags output. This allows
835 us to have public headers with Libxml2 stuff in them . It should also,
836 eventually, make Libxml2 checks redundant in packages using YAZ, such
839 --- 2.1.22 2006/06/15
841 Changed SRU update structure bend_update_rr so that SRU diagnostics are
842 stored in uri, message and details.. Previously diagnostics were stored
843 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
844 compatibility.. but he's probably the only one affected, so.
846 Added support for CCL, compiled on the client side, in ZOOM-C. This
847 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
848 input; the resulting query objects can be used for for searching with
849 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
851 YAZ' configure searches for OpenSSL by default.
853 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
854 SL_CTX_use_certificate_file. See
855 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
856 for more info. Thanks to Ko van der Sloot.
858 --- 2.1.20 2006/06/02
860 Bug #600: SRU GET, POST support for yaz-client. Introduced
861 command 'sru' which selects method SOAP/GET/POST.
863 Allow missingValueAction to be specified for the sortspec string -
864 function yaz_sort_spec. By default, the missing value action is null.
865 Use ! to specify "abort". Use = followed by stringvalue to specify default
868 Ensured that Present-handler (if defined) is called in GFS before any call to
869 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
870 searchRetrieve requests.
872 Documentation for YAZ is now based on the Docbook XML/XSLT using
873 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
874 is no longer depending on jade/openjade or docbook-to-man scripts.
875 PDF is no longer part of the distribution - but can optionally be
876 made using DSSSL/jadetex or FOP.
878 Added retrieval handling support in Generic Frontend Server to support
879 conversion between MARC/XML as well as XSLTtransforms. See
880 etc/yazgfs.xml for an example.
882 Added Authentication support to Generic Frontend Server in SRU
883 mode. Authentication using HTTP Basic is supported, as is the use
884 of 'x-username' and 'x-password' parameters in the request itself.
886 Added support for a new character set MARC8s identical to MARC8 except
887 that it converts combined characters to single Unicode characters in the
888 Latin-1 range (when possible).
890 --- 2.1.18 2006/04/24
892 ASN.1 compiler 0.4: generates brief Doxygen file header for
893 generated .h/.c files.
895 Utility yaz_iconv now supports conversion to MARC-8.
897 New facilities for the MARC module. The reading - and writing of
898 content are separate methods for the yaz_marc_t handle. The following
899 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
900 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
901 format). Write functions have prefix yaz_marc_write_.. The existing
902 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
903 available. Removed support for OAI-MARC and simplexml (not the
904 simplexml from PHP5).
906 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
907 to be returned for this connection.
909 --- 2.1.16 2006/03/31
911 Allow multiple languages and charsets to be specified with
912 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
913 negcharset iso-8859-1,utf-8
915 Translation of proximity nodes from CQL into PQF now works.
917 Moved to automake 1.8, 1.9.
919 Added function yaz_log_set_handler which allows a log handler to be
920 installed. This handler will be called for all log messages. Output
921 to file is also produced; but that can be disabled by passing NULL
922 fname to yaz_log_init_file.
924 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
926 For SRW (including GFS), accept application/soap+xml as content-type
929 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
930 produces NO stylesheet reference even if a default stylesheet is specified
933 --- 2.1.14 2006/03/14
935 Updated Windows package to include yazd.dll + yazd.lib for the
936 Development component.
938 If the environment variable YAZ_LOG is set, then it is used as a
939 string indicating the default level of logging to use if not
940 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
941 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
942 used as before. So, for example, to omit warnings from YAZ logging,
945 cql_transform() now map structure and other attributes before indexes,
946 so that index-specific structures and other attributes can override
947 defaults. So now a combination of mapping specifications such as:
949 index.dc.date = 1=date-modified 4=5
950 does the right thing.
952 cql_transform() now also respects the "always" mapping specification,
953 which establishes an initial set of attributes to be used for all
954 terms except where overridden by more specific attributes associated
955 with the index, relation or modifier.
957 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
958 which mode to use; one of "post", "get" or "soap" (SRW, default).
960 Fixes for yaz_iconv routines: changed trie-based character set conversions
961 to use only non-negative values for bit fields due to Sun's C compiler not
962 supporting negative values.
964 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
965 sequences where not read correctly. Fix by Rustam Usmanov.
967 Updated win/makefile to use options, settings which makes things
968 compile with VS C 2005.
970 --- 2.1.12 2006/02/01
972 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
974 In ZOOM socket code, use select instead of poll on MacOSX.
976 ZOOM-C now support client-side compilation of CQL into RPN that is
977 sent to the server, enabling CQL to be used against all Z39.50
978 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
979 ZOOM_query object, and submit it using ZOOM_connection_search().
980 The CQL-to-RPN translation uses a configuration file, the name of
981 which must be specified in the Connection's "cqlfile" option.
983 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
984 function, which takes as its start-term parameter a ZOOM_query object
985 (which may have had either CQL or RPN set into it).
988 --- 2.1.10 2005/11/29
990 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
991 GFS to support this as well. Backend handler, bend_srw_update, does the
992 update work. Code contributed by Ko van der Sloot.
994 Allow retrieval of Search Result-1 information in ZOOM by the use of
995 options that are attached to a result set. ZOOM documentation updated
998 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
999 UTF-8 conversion. Patch by Raj Patel.
1001 Added option -m to GFS to control formatting of timestamps in log file.
1003 Added 'exit' as synonym for 'quit' in yaz-client
1005 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1006 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1007 for the new members. Patch by Ko van der Sloot.
1009 Added support for SRU POST. It is supported for content-type
1010 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1012 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1013 Instead make the library libyaz.la multi-threaded. Threading as a whole
1014 can still be disabled by configure option --disable-threads. Previosly,
1015 with older GLIBCs there were problems with MT libs under Apache. This
1016 has now been fixed a long time ago.
1018 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1021 CQL module modified to be case insensitive for relations/indexes/operations.
1023 Fixed bug in CQL transform code: incorrect value relationModifieder
1026 Added 'show all' command for yaz-client which retrieves all results
1029 Added new yaz-client, xmles, which takes a (private) OID and
1030 a document to be sent as an extended service request.
1032 Describe new yaz-client commands wait_response and set_auto_wait.
1034 Increase TCP/IP listener backlog from 3 (which I am guessing was
1035 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1036 that the socket will queue as many incoming connections as it's able
1037 to handle ongoing connections. In other words, it will never now
1038 refuse a connection that it would be able to handle merely because
1039 it's not got around to accepting() enough of the pending connections
1040 yet. This is the behaviour anyway under Linux, where the listen()
1041 argument is ignored; but not under BSD and on systems such as
1042 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1043 YAZ-based servers should now be uniform across operating systems in
1046 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1047 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1048 This allows yaz-marcdump to read large MARC batches (>2 GB).
1050 Modified all YAZ source files - except the source which is auto-generated
1051 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1054 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1055 corresponding to the existing *_setl() function. These allow option
1056 values containing arbitrary valuues.
1058 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1059 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1060 except that it returns an indicator of whether or not the sort
1061 criterion was accepted (0 for OK, -1 for invalid).
1063 --- 2.1.8 2005/06/07
1065 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1066 MARC output rather than returning "new" buffer.
1068 yaz-client warns about unknown init options.
1070 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1072 --- 2.1.6 2005/05/24
1074 Added support for SRW sort in Generic Frontend Server. Patch
1075 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1076 sortKeys - or NULL if none is provided.
1078 Fixed bug #307: It was impossible to specify indefinite/no timeout
1079 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1082 Added support for multiple languages and charsets to be specified in
1083 ZOOM. Each charset/language is separated by a blank. If negotiation is
1084 in effect in init-response, Option
1085 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1086 Code based on patch by Vasiliy Osadchuk.
1088 Fixed bug #306: infinite recursion that occurred when calling
1089 yaz_log_level_init as the first call (before other log level or
1092 Fixed bug in scan handling in front end server: if preferred-Position-In-
1093 Response was non-present, a NULL pointer referece was performed.
1095 --- 2.1.4 2005/04/26
1097 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1098 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1099 now defined for all those error codes. So instead of putting 109 in
1100 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1101 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1103 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1106 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1108 Program yaz-client now exits and produces an error message if multiple
1109 Z39.50 servers are specified on the command line (none or one allowed
1112 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1115 --- 2.1.2 2005/03/16
1117 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1119 Fixed bug #272: Preserve spacing for CCL terms.
1121 --- 2.1.0 2005/03/14
1123 Added support for virtual hosts and multiple backend servers for
1124 the YAZ frontend server. The configution is XML based and
1125 support specificition of CQL to RPN mappings and explain information.
1126 See section "Virtual Hosts" in the YAZ manual.
1128 Extended OPAC display utility. OPAC display utility renders
1129 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1130 to supplement yaz_marc_decode_wrbuf.
1132 Fixed a bug in MARC decoder that could caused it to crash for some
1133 invalid MARC records. More diagnostics and warnings where added in
1134 XML output (warnings, etc are stored in comments).
1136 --- 2.0.34 2005/02/08
1138 Fixes for UNIX domain sockets. Bug #261.
1140 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1142 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1143 Added yaz_marc_subfield_str which defines subfield lead string which is
1144 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1145 yaz_marc_endline_str which defines end of fields string used in
1146 YAZ_MARC_LINE format. Default string is newline.
1148 Experimental support for MarcXChange. This format can be produced
1149 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1150 http://www.bs.dk/standards/MarcXchange.xsd
1152 Added yaz-client commands scansize that sets maximum number of
1153 entries to be returned by scan.
1155 --- 2.0.32 2005/01/11
1157 Added support for SRW scan in yaz-client and Generic Frontend Server.
1159 * Added whereInList member to SRW Scan Term.
1161 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1163 Fixed NMEM system to return aligned blocks on the smallest boundaries
1164 that are suitably aligned for all possible types on the particular
1165 architecture YAZ is being built for.
1167 --- 2.0.30 2005/01/04
1169 Fixed numerious warnings that was issued with newer versions of GCC.
1171 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1172 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1175 Make YAZ Generic Frontend Server slightly faster.
1177 Enhance (and reduce) logging for Generic Frontend Server.
1179 Revert YAZ log system so that it flushes every write operation
1180 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1182 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1183 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1184 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1185 will effectively disable old definitions.
1187 --- 2.0.28 2004/11/09
1189 Added yaz_log_time_format which specifies log format using
1192 Added yaz_log_module_level which returns mask for a module. Value
1193 is non-zero mask a if module is enabled; zero if disabled.
1195 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1196 in include/yaz/cql.h.
1198 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1200 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1202 Fixed bug #172: RPM builds does not enable SSL.
1204 Doxyfile.in part of dist. Doxyfile generated by configure.
1206 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1207 are given and the corresponding component does not exist.
1209 Extend CCL documentation in YAZ reference. Describe r=r.
1211 --- 2.0.26 2004/10/01
1213 Fixed MARC->MARCXML conversion to properly deal with
1214 fields, subfields, indicators having non-ASCII characters.
1216 Fixed MARC->MARCXML conversion so that ASCII control characters
1217 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1220 Added YAZ GFS support for conversion from Z39.50 surrogate
1221 diagnostics to SRW surrogate diagnostics.
1223 Bug fix: YAZ GFS did not return schema in explainResponse.
1225 --- 2.0.25 2004/09/30
1227 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1228 now converts recordSchema to elementSetName as well as schema URI.
1230 Fixed bug in COMSTACK that prevented HTTP request packages from being
1233 --- 2.0.24 2004/09/29
1235 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1236 does not require white-space before and after the dash in a range, e.g.
1237 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1240 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1241 due to new GCC removing "redundant" code.
1243 Added yaz-client commands scanpos and scanstep that sets preferred
1244 position and step-size for scan.
1246 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1248 Added CCL utility ccl_qual_buf which parses one or more CCL
1249 spec lines in a buffer.
1251 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1252 of name and value - ignoring empty lines and comments.
1254 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1256 Added odr_get_element_path which returns current element path for an
1257 ODR handle. This utility is useful in error handling or user-defined
1260 Added ODR_PRINT utility odr_set_stream which is is a more generic
1261 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1262 to a write function and pointer to close function. The close function - if
1263 non-NULL - will be called during odr_destroy.
1265 Fixed bug in CCL parser where truncation char was not removed from
1266 right side when truncation=both was in effect.
1268 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1271 --- 2.0.23 2004/08/11
1273 Fix buffer overrun in CQL parser when dealing with proximity (%).
1275 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1276 to UTF-8/UCS conversion is now only based on codetables.xml.
1278 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1280 --- 2.0.22 2004/08/06
1282 Add support for more "commit changes" in ZOOM (uses Extended Services).
1284 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1287 Yet another small fix for configure of SSL.
1289 --- 2.0.21 2004/05/14
1291 Fix SSL libs for configure when --with-openssl=DIR is given.
1293 --- 2.0.20 2004/05/10
1295 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1297 SSL comstack now uses yaz.pem certificate file on server side
1298 by default. Certificate filename can be configured by calling
1299 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1301 Fix bug regarding multiple calls to ZOOM_connection_connect.
1303 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1305 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1306 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1308 ZOOM now allows inspection of X509 peer certificate for verification.
1309 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1311 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1312 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1313 as "modular" but it simplifies things.
1315 Added cs_get_peer_certificate to that returns peer X509 PEM.
1317 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1318 NULL if SSL is unavailable.
1320 Documentation about MARC decoding tools.
1322 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1324 --- 2.0.19 2004/03/30
1326 Rename CHANGELOG to NEWS to follow GNU style packing.
1328 Fix bug with missing initialization of member in init_diagnostics.
1329 This bug affects threaded version of GFS server.
1331 --- 2.0.18 2004/03/20
1333 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1336 Ensure zlib.dll is packed with Windows install.
1338 --- 2.0.17 2004/03/17
1340 Fix encoding of xsd:string to use text instead of CDATA.
1342 Fix endless loop in CQL parser with unbalanced ".
1344 Use a more compact way to store MARC-8 conversion tables.
1346 --- 2.0.16 2004/03/16 Debian only
1348 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1351 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1356 --- 2.0.15 2004/03/01
1358 Another fix for decoding of XML packed records.
1360 --- 2.0.14 2004/02/25
1362 Fixes for Chunked encoding. White space not ignored after length spec.
1364 Update NS and use default NS for SRW diagnostic elements.
1366 --- 2.0.13 2004/02/23
1368 Implement ZOOM_resultset_cache_reset which resets record cache.
1370 Implement ZOOM_resultset_sort which sorts a result set.
1372 Implement chunked HTTP transfer.
1374 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1376 --- 2.0.12 2004/02/16
1378 Added member 'schema' to bend_explain_rr structure so that backend
1379 can specify explain record identifier. Defaults to Zeerex 2.0.
1381 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1383 --- 2.0.11 2004/02/16
1385 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1388 Added init command for yaz-client which sends "extra" init request.
1390 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1391 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1393 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1395 Make ZOOM error code for "invalid query".
1397 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1399 --- 2.0.10 2004/02/05
1401 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1404 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1406 Added option -p <file> to make Generic Frontend Server to write PID file.
1408 Added option -D to put Generic Frontend Server in background on its own.
1410 Make ZOOM C recognize option "password". If unset, "pass" is used
1411 (for backwards compatibility).
1413 Fixed a bug in Generic Frontend Server that could make it crash if a
1414 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1417 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1418 Must be issued before open, in order to be in effect.
1420 --- 2.0.9-6 2004/01/12 Debian/Windows
1422 Make the SRU server more picky WRT unknown params, etc.
1424 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1426 New YAZ client command, options, that sets Z39.50 options.
1428 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1429 options from a string of tokens (one token for each option bit).
1431 Update SRW diagnostic code messages.
1433 --- 2.0.9-5 2004/01/07 Debian/Windows
1435 Handle user defined stylesheet for SRW/SRU.
1437 --- 2.0.9-4 2004/01/06 Debian/Windows
1439 Fix bug in decoding of Content-Length.
1441 --- 2.0.9-3 2004/01/06 Debian/Windows
1443 Fix a bug with decoding of XML packed records.
1445 --- 2.0.9-2 2004/01/05 Debian only
1447 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1449 Fix bug in SRW/SRU diagnostics decoding.
1451 --- 2.0.9 2004/01/05
1453 Fixed bug in Generic Frontend Server which could drop records exceeding
1454 preferred message size. Reported and fixed by Irina Dijour.
1456 Fixed calculation of package size for structured records in Generic
1457 Frontend Server. Reported and fixed by Irina Dijour.
1459 Fixed namespace for SRW/SRU diagnostics.
1461 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1463 --- 2.0.8 2003/12/22
1465 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1466 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1469 CQL changes to reflect recent changes to the specification:
1470 * Documentation talks about context sets instead of index sets.
1471 * Documentation talks about indexes instead of qualifiers.
1472 * The CQL-to-PQF transformer's configuration file now uses
1473 "index.set.name = <attributes>" instead of the old form
1474 "qualifier.set.name = <attributes>". (Both forms are still
1475 understood but the latter is deprecated.)
1476 * CQL terms with no explicit index specified are now interpreted as
1477 cql.serverChoice instead of srw.serverChoice (which of course
1478 behaves exactly the same.)
1480 --- 2.0.7 2003/12/16
1482 MARC conversion can now generate ISO2709 output in another
1483 character set. yaz-marcdump uses this facility if you invoke it
1486 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1487 functions from there can be used from C++.
1489 --- 2.0.6 2003/12/04
1491 Frontend server now transfers memory from decoded packages to stream
1494 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1495 references to show up.
1497 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1498 the ZOOM Abstract API. The older names for the same options are still
1499 also supported for the benefit of old applications.
1501 ZOOM-C supports "implementationId" and "implementationVersion" options
1502 to go along with "implementationName". These allow the user code to
1503 specify identification strings to be sent to servers.
1504 Add OID for the new ExtLite attribute set.
1506 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1507 as requested/supplid by Ere Maijala <ere@atp.fi>
1509 For generic frontend server, reverse the order of
1510 "toolkit-supplied / application-supplied" strings sent as implementationId,
1511 Name and Version. Also, remove the spaces around the slash. This brings
1512 the GFS in line with the behaviour of ZOOM-C on the client side.
1514 Add function ZOOM_scanset_display_term.
1516 yaz-client shows scan displayTerm if present.
1518 Utility yaz-iconv is now installed by default along with the man page
1521 Extend configure check for OpenSSL to use pkg-config where available (such
1524 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1525 server to specify uid/gid/mask for socket using the format
1526 unix:[user=uid,][group=gid,][umask=mask,]file=path
1527 If file= is omitted the existing format is assumed, e.g.
1529 in which case the mask is 0666 (rw for everybody).
1531 Major restructure of YAZ source. All source in libyaz is in src directory.
1532 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1533 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1535 Added man page for utility yaz-marcdump (used to be called marcdump).
1536 yaz-marcdump is installed by 'make install'.
1538 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1539 of incoming package failed.
1541 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1543 Change prototype of odr_perror: add const to message string.
1545 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1547 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1548 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1549 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1550 DNS lookup. There should not be any compatibility problems with this
1551 assuming that blocking=1 or 0 is used.
1553 Fix bad reference in UNIX comstack in function cs_addrstr.
1555 Fix for compilation on AIX.
1557 The generic front-end server (server/seshigh.c) now supports returning
1558 Init diagnostics to the client in User-information-field, in
1559 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1562 --- 2.0.4 2003/09/04
1564 Allow any CQL relation (not just all,any,exact,scr).
1566 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1567 that features the same UI.
1569 Implemented command update0 in YAZ client which is equivalent to
1570 update but uses old of Ext Update ASN.1.
1572 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1573 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1574 Previously no OID was used for this info.
1576 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1577 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1578 returns 'malformed search term' otherwise.
1580 SortResponse member resultCount now set to NULL in sort handler of
1583 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1586 Add three new utility functions for translating OIDs between various
1587 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1588 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1589 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1590 char *oid_to_dotstring(const int *oid, char *oidbuf);
1591 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1593 Reverted modifications for ES Update definition for z_IU0Update
1594 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1595 is back to YAZ 2.0.2.
1597 String value attributes for CCL parser.
1599 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1600 which their FirstSearch server returns in Init responses, sometimes
1601 carrying useful diagnostic information when Init fails. This has the
1602 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1603 "z39.50/oclcui.asn", where its definition is somewhat different from
1604 what OCLC document on their web-site, as required to interoperate with
1607 Support for anonymous authentication in yaz-client. Use the command
1610 * Fix the OID of the Index Data-local "admin" Extended Service from
1611 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1612 the 1000, which indicates a locally-defined OID, was a mistake.
1614 --- 2.0.3 2003/06/20
1616 Fix CCL directive @case handling so that it affects string match for
1617 both CCL keywords and qualifiers.
1619 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1620 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1621 Decoder has been updated with ASN.1 changes as listed in
1622 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1623 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1624 z_IUUpdate, remains unchanged.
1626 ZOOM_record_get may now return a record in a specific character set.
1627 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1628 "from" is the character set of record as returned by target. "to" is
1629 the character set to be returned. If omitted, "to" is UTF-8.
1631 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1633 New ODR utility, odr_getelement, which returns name of element for
1634 which encoding/decoding failed.
1636 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1637 in cases where a required element was omitted.
1639 Bug fix: some MARC8 sequences were not converted.
1641 New ZOOM option "step" which specifies number of records to be
1642 retrieved in one chunk. Used in conjunction with "start" and "count".
1644 SRW support for yaz-client. Use scheme http: to use it, e.g.
1647 yaz-client no longer does (un)intelligent character set conversions
1648 by default. Can be enabled with charset and marc_charset commands.
1650 xmalloc trace fix for 64-bit systems such as DEC alpha.
1652 Solaris 2.6 compile fix.
1654 New function, cql_strerror() translates SRW error codes, as returned
1655 by cql_transform_error(), into human-readable English strings. Used
1656 in yaz-client diagnostics when appropriate.
1658 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1659 converts it into a type-1 query which is sent to the server. This
1660 makes CQL available for use with all Z-servers, as opposed to the tiny
1661 minority that can handle CQL queries themselves.
1663 --- 2.0.2 2003/04/28
1665 New Debian package layout similar to the Redhat Package layout.
1667 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1668 and search result respectively.
1670 --- 2.0.1 2003/04/25
1672 Redhat package is now several packages: libyaz (runtime libraries),
1673 libyaz-devel (development and documentation, and yaz (utility programs).
1674 Package spec file by Morten Bogeskov.
1676 New member 'schema' in struct bend_fetch_rr which the name of requested
1677 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1678 handler MAY set this to reflect the schema of the returned record.
1680 New member 'display_term' in struct scan_entry. GFS now sets member entries
1681 and allocates scan entries to be filled by user scan handler. In previous
1682 version, entries member was allocated by the scan handler. That still works,
1683 but the GFS will ignore member display_term - assuming it was NOT set by
1684 the handler. The fact that the GFS now allocates the entries both allows
1685 for new members and makes a scan handler easier to write.
1687 Fix CQL lex buffer overflow.
1689 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1690 SRU default recordPacking is string.
1692 SRU protocol support for frontend server.
1694 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1696 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1698 Added scan for the ZOOM shell (zoomsh).
1702 * String Identifers for Schemas (Amendment 5).
1703 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1704 Old definition for schema
1705 Odr_oid *schema; /* OPT */
1710 Z_InternationalString *uri;
1711 #define Z_Schema_oid 1
1712 #define Z_Schema_uri 2
1715 * resultCount parameter to Sort Response (Amendment 1).
1716 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1718 Support for SRW 1.0 over HTTP. This is an optional feature and
1719 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1722 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1723 on the same port. SRW SearchRetrieveRequests are mapped
1724 to bend_init,bend_search,bend_fetch,bend_close.
1726 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1728 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1729 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1731 ZOOM connections are SRW based if schem http is used for hostname
1732 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1733 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1735 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1736 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1737 distance=n, order=true/false, relation=le, prox unit=word. If
1738 n is omitted, distance 1 is used.
1740 Fixed problem with C compiler include path in wrong order.
1742 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1743 on Solaris. Patch from Ko van der Sloot.
1745 New MARC decode API. All new functions operate on a yaz_marc_t
1746 handle. The most important new functions are: yaz_marc_create,
1747 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1748 decode and destroy respectively. Decoder can produce formats
1749 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1750 include/yaz/marcdisp.h.
1752 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1753 to UTF-8, UCS-32, wchar_t or Latin-1.
1755 * Prototypes for yaz_iconv_-functions moved to separate header
1756 include/yaz/yaz-iconv.h.
1758 Make a few private functions 'static' in unix.c. This prevents
1759 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1761 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1762 are set when Init Response is received.
1764 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1765 but returns diagnostic set as well.
1767 New function yaz_strerror which is a portable wrapper for
1768 strerror/strerror_r/GetLastMessage.
1770 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1771 is returned for MARC. If type is "oai", then OAI MARC is returned.
1773 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1776 --- 1.9.2 2002/11/26
1778 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1780 Fix bad race conditions on SIGTERM and terminate gracefully in
1783 Move retrieval (data1) module to Zebra since nobody seems to be
1786 Add GRS-1 render for ZOOM using same format as yaz-client.
1788 --- 1.9.1 2002/10/05
1790 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1792 Fix broken ESpec handling in data1 module.
1794 SGML reader parses comments and makes them part of the data1 tree.
1796 Added several type casts so that YAZ compiles as C++ code.
1798 ZOOM didn't handle PDU encoding failures properly.
1800 Added more Bib-1 diagnostics (approved extensions).
1802 GNU configure: better check for iconv.
1804 More portable use of accept, getpeername. Check for socklen_t. Use
1805 int/size_t if socklen_t is not defined.
1809 PQF parser rejects bad queries - including those with extra
1810 characters in them. PQF parser used to silently ignore that.
1811 Cleaner API for PQF added, which allows you to get detailed
1812 error information for bad queries (see yaz/pquery.h).
1814 Fixed bug in ZOOM_record_get for type "database".
1816 Implemented mini iconv library supporting conversions between
1817 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1819 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1821 --- 1.8.9 2002/08/20
1823 Fixed ZOOM C record cache so that preferredRecordSyntax and
1824 elementSetName is used to check for already fetched records.
1826 --- 1.8.8 2002/08/02
1828 Added three members in bend_initrequest structure to facilitate
1829 character set negotiation.
1831 Fixed a bug in frontend server that could cause indefinite
1832 loops under rare conditions.
1834 Revised character set utilities (charneg.h) so that encoding
1835 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1837 For PQF, directive @term <type> sets term type for Scan/Search.
1838 Here <type> is general, string, numeric, null. The term type
1839 is inherited - just like @attr.
1841 New call odr_set_charset that sets character set conversion for
1842 international-strings on a ODR stream. Prototype is:
1843 int odr_set_charset(ODR o, const char *to, const char *from);
1844 The InternationalString is still represented as C string in YAZ
1845 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1846 won't). On the protocol level, you can use any encoding.
1848 Support for UNIX sockets in ZOOM.
1850 Solaris recv sometimes returns errno == ENOENT. It is treated as
1851 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1853 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1854 both client and server. Code by Morten Bogeskov.
1856 --- 1.8.7 2002/05/22
1858 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1859 that they can be used directly from Visual Basic. You must recompile
1860 your windows APP if you're using ZOOM.
1862 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1863 Commands "lang" and "charset" sets language and character set respectively.
1864 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1865 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1867 Attributes from multiple CCL fields may be OR'ed rather than merged
1868 using directive "@field or". Fields are still merged by default -
1869 equivalent to "@field merge".
1871 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1874 Fixed bug in zget for parameter ExtendedServicesResponse.
1878 --- 1.8.6 2002/03/25
1880 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1882 Client displays USR.1:SearchResult-1 (hits per term).
1884 Additional Search Info for search in Generic Frontend Server.
1886 Fixed CCL parsing of "field=s".
1888 WIN32 installer - using the excellent NSIS software from nullsoft.
1890 Fixed CCL parsing of "field = - <number>".
1892 Added function yaz_marc_decode that decodes MARC for line mode
1893 display or XML (similar to that used by JZKit).
1895 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1896 Z39.50. But ISO/ILL was, however.
1898 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1899 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1902 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1904 --- 1.8.5 2002/02/03
1906 New YAZ client features: Command completion and new commands:
1907 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1908 Code provided by Jacob Poulsen.
1910 New call oid_trav, that visits all registered OIDs via callback.
1912 Function ZOOM_record_get now returns const char pointer rather than
1913 void pointer. It saves a lot of type casts.
1915 For YAZ client, command "auth" now allows you to set authentication
1916 in IdPass style. It is enabled when three tokens are given - order
1917 is user, group and password.
1919 Fix memory leaks in MARC record handling for ZOOM.
1921 New option for YAZ client, -k <kilobytes> that sets
1922 maximum record size. Similar to -k option for generic frontend
1923 server and yaz-ztest.
1925 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1927 Prefix query parser reports "fail" when bad attribute set is given.
1929 Fix in MARC decoder. Proximity logging. Fix for attribute set
1930 in scan handler for server. Patches by Shigeru Ishida.
1932 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1935 Configure option --with-openssl=<dir> now works when a directory is
1936 specified. Patch provided by Morten Bogeskov.
1938 New option for YAZ client, -u <auth>, that sets authentication.
1940 ZOOM fix: error information was sometimes "missing", since error
1941 was cleared/reset too when it shouldn't.
1943 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1945 --- 1.8.4 2002/01/04
1947 Scan for ZOOM API. New object ZOOM_scanset. New functions
1948 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1949 ZOOM_scanset_destroy.
1951 New ZOOM function, ZOOM_connection_last_event, that returns type
1952 of last event (such as "receive data", "send data", "apdu received",
1955 New ZOOM option, schema, that specifies schema for retrieval.
1957 New CCL feature. Qualifiers can be aliases for one or more
1958 other qualifiers (if more than one is given, OR is used).
1960 ZOOM uses named result sets if target supports it.
1962 Two new YAZ client commands: . (dot, which sources a script of YAZ
1963 client commands), and ! (to execute shell command.). Implemented
1966 Working on Debian packages.
1968 --- 1.8.3 2001/11/19
1970 YAZ client enables named result sets only if target supports it.
1972 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1974 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1975 with key="host" to get same result.
1977 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1978 Function Z3950_resultset_record(s) returns references to records
1979 "owned" by resultset. To become owner use Z3950_record_clone.
1981 Function z_ext_record handles Extended Services. Thanks to
1984 --- 1.8.2 2001/11/12
1986 CCL Parser fix: ignore token comma when dealing with and-lists.
1988 Documentation updates for COMSTACK.
1990 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1991 Changed prototype Z3950_records. For some functions, int parameters
1992 were changed to size_t.
1994 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1997 New MARC decode/display function, marc_display_exl, which properly rejects
1998 non-ISO2709 records. YAZ client uses it.
2000 --- 1.8.1 2001/10/29
2002 Fix bug: local attribute set wasn't set correctly in PQF strings.
2006 * Old Z39.50 codecs no longer supported.
2008 Added ZOOM C binding. See http://zoom.z3950.org/
2010 Renamed states for COMSTACKs to avoid confusion with events.
2012 Implemented cs_look and proper cs_rcvconnect.
2014 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2016 Configure detects POSIX threads on OpenBSD.
2018 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2019 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2021 When error is returned from present handler, non-surrogate diagnostic
2022 is returned in present response (and fetch handler is no longer called).
2024 * Minor adjustments to pquery parser (PQF). Token characters may be
2025 escaped by using backslash (C-style).
2027 PQF parser allows string attribute values to be specified. For @attr,
2028 non-numeric characters after the equal-sign are treated as strings
2029 (e.g. @attr 9=title).
2031 CCL trunction character may be defined (@truncation in file)
2033 * function zget_ExtendedServicesRequest sets waitAction to
2034 waitIfPossible (was wait).
2036 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2039 CCL operator names may be set in field definition files (CCL_bibset).
2040 See ccl/bib1 for an example.
2042 Fixes in ASN.1 compiler for C++ compatibility.
2044 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2045 and "op_or" to avoid conflict with C++.
2047 Fixed problem with GNU readline detection on Redhat 7.0.
2049 Added step-size for Scan backend handler.
2051 Fixed bug that made the frontend server crash when no attribute
2052 set was specified for scan.
2054 Front-end server automatically switches to original working directory
2055 when installed as an NT service. Previously -w had to be specified to
2058 Added extended attributes for retrieval module (data1), so that data1
2059 records carry d1_readXML/SGML attributes. d1_read also supports
2060 null-data rules ( <tag/>)
2062 On UNIX when POSIX threads are available, a separate library libyazthread
2063 is created. Programmers should link with that library and the yaz library
2064 when using threads. The reason for the split was that some applications
2065 on Linux, such as Apache, doesn't work well when using shared objects that
2068 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2069 (or any frontend server) in SSL mode by specifying ssl: followed by
2070 address. Only tested on UNIX.
2072 Added feature for CCL module. Virtual structure s=al or s=ol generates
2073 and-list and or-list respectively instead of phrase search.
2077 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2078 log_mask_str. This was done to avoid name conflicts with other libraries
2079 (such as other PHP extensions).
2081 Added raw OID member for preferred record syntax (request_format_raw)
2082 and returned record syntax (output_format_raw) for backend fetch method.
2084 Config file yaz-config now accepts options so that it returns specific
2085 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2087 Shared library support for UNIX using GNU libtool.
2089 * Modified backend interface. Request/Response struct's replaced by
2090 one read/write C struct. For example bend_fetchrequest and
2091 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2092 Every handler - even search has to be registered in bend_init
2093 handler. This means that the YAZ library no longer refers to
2094 external functions and it makes it possible to make the whole
2095 thing a single DLL/SO.
2097 Added Segment handler for backend server.
2099 Added Zmbol/Zebra administrative functions to YAZ client.
2101 Threaded frontend server on UNIX (when POSIX Threads are available).
2102 Starting the server with option -T enables multi-threading.
2106 Added configure option --enable-comp/disable-comp to control use
2107 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2108 located in sub directory asn.
2110 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2111 in ${exec_prefix}/bin along with the other programs yaz-client and
2114 GNU automake used to maintain makefiles.
2116 Added several OID's.
2118 Changed retrieval module so that we can load records with no abstract
2119 syntax defined. Tagpaths in these records are fully composed of string
2122 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2126 On UNIX, the generated makefile now supports a proper 'make install'.
2127 The prefix can be set via GNU configure to set the install location
2128 (default is /usr/local).
2130 * YAZ programs client and ztest were renamed to yaz-client and
2131 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2132 locations, such as /usr/bin,/usr/local/bin,etc.
2134 * YAZ Header files were moved from include to include/yaz. YAZ Header
2135 files are referred to as include <yaz/log.h> rather than <log.h>.
2136 The YAZ include path (-I ..) is therefore the same as before. Programmers
2137 should update their #include statements or use -Ipath/include/yaz
2138 instead. The main motivation for doing this change is that YAZ header files
2139 can be installed in "standard" locations /usr/include,/usr/local/include
2140 without introducing conflicts, since ALL YAZ header files are stored
2141 in subdirectory yaz (under /usr/include for example).
2143 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2144 rather than project/workspace files. We switched because project files
2145 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2148 Changed name of logging function, logf, to yaz_log, to prevent name
2149 clash with some math-log functions. The YAZ header log.h defines logf
2150 to yaz_log (#define) so there should be no incompatibilities by this
2153 Added bend_start/bend_stop handlers for server. These handler are
2154 called on start/stop of server. For windows they are called whenever
2155 a service is started/stopped.
2157 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2158 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2159 in util/yc.tcl. The auto-generated C code structures are, in a few
2160 cases, incompatible with the old decoders. There are differences in the
2161 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2162 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2163 The preprocessor variable ASN_COMPILED is defined when the compiled
2164 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2165 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2166 wish to use the old encoders/decoders you can specify --disable-yc
2169 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2170 version so that it supports both new - and old version of DB Update
2172 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2173 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2174 change. The name parameter can be set to 0 in which no name is specified
2175 for the construction. The macros odr_implicit and odr_explicit sets name
2176 parameter to zero for the construction involved. New macros
2177 odr_implicit_tag and odr_explicit_tag are similar to the others,
2178 except that a name parameter is added. For programmers' that don't use
2179 ODR they probably only need to change the call to z_APDU and z_External.
2181 Added access control facility by interfacing the TCP wrapper library.
2182 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2183 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2184 name of the daemon and enables the access control as specified in
2185 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2187 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2188 den Dool <H.M.vdnDool@kub.nl>.
2190 Added reference ID parameter to most functions in server API - refer
2191 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2193 Changed name of ccl library to libccl.a (was ccl.a).
2195 Fixed bug in decoder for Explain (Category TargetInfo).
2197 Added support for GNU readline in client. Thanks to Jacob Poulsen
2198 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2200 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2201 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2202 IMPLEMENTATION! This change was made to the development version before
2203 the ZIG decided to retract the amendment. If any users MUST be
2204 compatible with the original Update definition, PLEASE CONTACT US, and
2205 we will include a separate definition corresponding to the old Update
2206 ES. Note that because of the change to the ASN.1 of the
2207 TaskPackageRecordStructure we cannot define a single structure that
2208 will support both versions.
2210 * Added const modifier to buffer parameter for some ODR/BER encoding
2211 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2212 completeWAIS, odr_dumpBER.
2214 Fixed bug in client.c which caused a crash when a scanResponse didn't
2215 contain positionOfTerm.
2217 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2218 * will cause an error in a client if a non-YAZ target sends both a
2219 * list of Scan entries and non-surrogate diagnostics.
2221 Retrieval module enhancements. Tag sets may be typed in the reference
2222 to it. From the .abs-file the "tagset" directive takes a third optional
2223 integer type for the tag set referenced. From a .tag-file the "include"
2224 directive takes a third optional type as well. The old "type" directive
2225 in the tag set itself is still recognized but acts as the default type
2228 Backend interface change. Individual Scan terms returned from bend_scan
2229 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2230 in include/backend.h.
2232 Retrieval module enhancements. Multiple tag sets and attribute sets may
2233 be specified in abstract syntax specs. Revised the error/warning for
2234 logging messages reported by the retrieval module when reading the
2237 Object Identifier system (oid_..) changed. The API is backwards
2238 compatible but the oid-routines now allocates new OID's when needed.
2239 Raw OID's may be specified in oid_getvalbyname.
2241 YAZ now uses GNU configure to generate Makefile(s).
2243 * Minor changes in some of the member names of DeleteResultSetRequest and
2244 DeleteResultSetResponse. See include/proto.h.
2246 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2247 and added member 'languages' in TargetInfo (which was missing).
2249 Changed the way attribute sets are handled in the retrieval
2250 module. These are now cached, just like the abstract syntaxes
2253 Changed YAZ so that it links with compiled ASN.1.
2255 Added Explain-schema definitions and mapping routines. The following
2256 Explain categories have been implemented: AttributeDetails,
2257 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2259 Fixed minor bug in Windows version of Server Library.
2261 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2263 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2265 Added EXTERNAL: UNIverse Resource Report (non-standard).
2267 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2268 ENUMERATED and SET OF.
2270 * Added 'const' to some of the char pointer arguments for the
2271 functions, data1_read_node, data1_getelementbytagname,
2272 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2275 Fixed bug in data1_insert_taggeddata - the last_child member of
2276 parent wasn't initialised.
2278 * Changed data1_read_record and data1_read_node so that the supplied
2279 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2280 doesn't refer to any parts of the "SGML"-buffer.
2282 Fixed bug in server library (Windows version of statserv_remove).
2284 * Changed code so that it compiles as C++. The type definition
2285 of Odr_fun which is a member of Odr_arm was changed. The result is,
2286 that an explicit typecast is needed for the fun pointer when
2287 using Odr_arm - as in:
2288 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2290 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2292 Implemented the new structured date and time definition as approved
2293 by the ZIG. Added schemaId element to the specificTag in Espec-1
2294 (also approved at the last ZIG). Thanks to RVDM.
2296 Added some Object identifiers (RVDM).
2298 Changed the Update Extended Service (RVDM).
2300 Added command "refid" to client which specifies referenceId for
2301 the following requests.
2303 Implemented extended service handling for server. See ztest.c
2304 for an example as well as backend.h. New handlers are registerd
2305 in the Init handler.
2307 * Changed interface for sort in server.
2309 Added new members to statserv_options_block. It allows a server
2310 to read options from another source than just the command line. Thanks
2311 to Charles Woodfield.
2313 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2314 renamed to zboolean. Some C++ compilers complained about the name.
2316 Minor changes to gils.abs. Added index 's' (sort) on title
2317 and date/time-last-modified.
2319 --- 1.4pl2 1998/1/30
2321 Fixed bug in server library regarding inetd mode (-i). This bug
2322 was introduced by release 1.4.
2324 --- 1.4pl1 1998/1/29
2326 Added sort facility in client and backend server interface.
2328 Fixed problem with dependencies in Makefile(s).
2330 Fixed bugs for encoders/decoders of extended services and
2333 Implemented sub-tree feature for schemas. Sub-trees are
2334 referenced in *.abs-files. See explain.abs for an example
2335 of the use of this feature.
2337 Modified bib1.att; local attributes for ANY didn't include
2338 ANY itself (only affects use of the retrieval module).
2340 Fixed bug in plain SGML reader in function data1_read_node:
2341 tags with prefix "var" was incorrectly interpreted as variants.
2343 Added feature "sub-schemas" to enable references to - and definitions
2344 of - group of elements.
2346 * Removed member parent from type data1_element (in data1.h).
2348 Implemented function odr_nullval() that returns the value of
2351 * Removed member num_children from data1_node (in data1.h).
2353 Made NT service interface part of the server library. The
2354 function statserv_main uses the NT service when required and
2355 calls the statserv_start / statserv_close routines.
2357 Routine zget_SearchRequest and zget_PresentRequest fills
2358 resultSetName/Id member with "default" instead of "Default".
2360 Fixed memory leak in server. Request queue member wasn't freed.
2362 Fixed nmem_exit so that memory is freed.
2366 Revised the CCL parser utility to be thread safe.
2368 Added function, oid_ent_to_oid, to replace the function
2369 oid_getoidbyent, which is not thread safe.
2371 * Added nmem_init and nmem_exit to initialize and release
2372 NMEM resources. Function nmem_init should be called once in the
2373 initial thread before NMEM/ODR is used. statserv.c and client.c
2374 have been changed accordingly. The change was necessary to make
2375 NMEM thread safe. The NMEM memory pool is shared amongst threads
2376 in a process. Unix-based applications will still work fine without
2379 Added NT Services interface for the the Z39.50 (statserv) Server.
2380 Refer to the ztest.c source on the usage.
2382 Windows 95/NT port using MSVC5.0. Project files are included in the
2385 * Defined new 'global' handle for the retrieval (data1) system. The
2386 new handled, data1_handle, describes the state of the data1 system.
2387 This handle is passed as first argument to virtually all
2388 data1 related routines. The functions data1_create and data1_destroy
2389 creates and destroys a data1 handle respectively.
2391 Added ODR encode stream member to all backend request structures
2392 init, search, scan etc. This stream should be used to allocate all
2393 memory used for the response when thread safe operation is needed.
2395 Changed the comstack utility, cs_addstr, to be thread safe. The
2396 returned hostname string returned by the function is now part the
2399 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2400 function. The cs_straddr takes a COMSTACK handle as argument, so this
2401 function must be used after cs_create and before bind/connect.
2402 This function is thread safe.
2404 Moved test server to 'ztest' directory - generic server code still
2405 in 'server' directory.
2407 Made prefix query (pquery.c) utility thread safe.
2409 Added new function modifier YAZ_EXPORT to 'export' public DLL
2410 functions when using windows (see include/yconfig.h).
2412 Added definitions to the OID database (util/oid.c) (RVDM).
2414 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2416 Added call to ccl_rpn_delete in client program.
2418 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2419 release of RPN structure.
2421 Added support for C++, headers uses extern "C" for public definitions.
2422 With input from RVDM.
2424 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2425 Thanks to Ronald van der Meer (RVDM).
2427 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2429 Added support for private extensions to the OID database
2430 (oid_setprivateoids()). Thanks to RVDM.
2432 Added optional, physical ANY (key replication)
2434 Fixed null-reference problem in GRS-1 output filter.
2436 Proximity operator added to Prefix Query Format (PQF).
2438 In test client command "base" accepts multiple databases.
2440 Fixed bug in cs_close stack that caused trouble with WINSOCK.

2463 --- 1.2 1996/6/10 (1st anniversary release)
2465 Added Summary record syntax. Lightly tested.
2467 Added OPAC record syntax. Untested.

2481 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2482 surrogate diagnostics were generated.
2484 [retrieval] Allow multiple local values for attribute.
2486 [retrieval] Allow multiple attributes per element in .abs files. index type.
2488 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2490 --- 1.1pl2 1996/4/10
2492 Minor changes, mostly specific to Zebra's requirements (retrieval)
2496 Repaired bug in frontend server when running multiple listening
2497 endpoints in dynamic mode.
2499 z_External() now won't break if a known, ASN.1 value comes encapsulated
2500 in an octet-string. The value will pass through unmodified in an Odr_oct.
2502 Added a bit of code to the demo client to decode & display
2503 ASN.1-structured records represented in the octet-aligned branch of
2504 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2506 Added z_ext_getentbyref() to the ASN module. Doc updated.
2508 * Completed the SCAN definition in the ASN module. This may break SCAN
2509 code based on older YAZ-versions at compile-time. The fix is easy -
2512 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2513 under the SCAN definition. Remember to initialize this, server-people.
2515 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2516 that this does not extend to ODR and ASN.
2518 Comstack allows insertion of established socket (primarily for
2519 inetd-operation of servers). Doc updated.
2521 Front-end server can now start from the inetd in TCP mode. Doc
2524 --- 1.0pl4 1996/1/24
2528 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2529 the rank and record number.
2531 Adjustments to the frontend server.
2533 Fixed diagnostic BER dumper. It ignored the file argument.
2537 Various changes to retrieval module.
2539 Changed the union discriminators of the protocol files from enums to
2540 ints paired with #defines.
2542 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2545 *Changed operator in the RPN structure to 'roperator', again to avoid a
2548 Fixed problems in Explain decoders/encoders.
2550 --- 1.0pl2 1995/12/6
2552 Memory bug in log module fixed.
2554 --- 1.0pl1 1995/12/5
2556 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2558 Bug in Explain DatabaseInfo module fixed.
2560 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2564 The shift to v1.0 signals that we now consider the *core* functionality
2565 of YAZ reasonably stable (the core being more or less equivalent to
2566 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2567 tested (Explain not at all - though that will happen soonish).
2569 Minor changes to code to support Windows port.
2571 Various minor changes after we're getting to use GRS-1 & co. more.
2573 Added Espec-1 format.
2575 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2576 of the protocol and it cannot be selected when encoding (maps into 'string'
2577 when decoding). Needed to talk to some servers.
2579 Demo client can request simple element set names.
2581 Added Diagnostic Format encoders/decoders.
2583 Added simple Close handling to frontend server (no hooks for resource
2584 reporting yet), and demonstration client.
2586 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2588 --- 1.0b3 1995/08/24
2590 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2591 handled incorrectly when records were requested in the searchResponse. This
2592 will only affect you if you use the frontend-server.
2594 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2595 Test-client will ask for and print GRS1. Ztest will return dummy records
2598 Added Explain encoders/decoders to the service-level API. Untested.
2600 Added Extended Services: Item Order encoders and decoders to the Service-
2601 level API. Untested. We could use a recent copy of the pertinent bits
2602 of the ILL protocol to add those bits.
2604 Added diagnostic format 1 encoders/decoders to the service-level API.
2607 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2608 odr_cons.c, which causes a more correct output.
2610 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2611 was always set to 0 when no records were requested in the searchRequest.
2613 * Added better external-handling. This shouldn't harm old code that
2614 *encodes* externals. It can break code that looks for a
2615 'single-ASN1-type' representation, since those types that are known
2616 are now decoded immediately. Look at the SUTRS sample code in
2617 seshigh.c and client.c. Documentation updated.
2619 Handling of structured records in bend_fetchresponse. Length -1 marks
2620 structured record, type is deduced from format field.
2622 --- 1.0b2 1995/06/27
2623 Fairly quick maintenance release to add SUTRS support.
2625 Fixed handling of SUTRS records in the demonstration client.
2627 * Added format field to the bend_fetchrequest and bend_fetchresponce
2628 structures of the backend API (frontend server). When the record is
2629 returned, the value of the format field is mapped to an OID. The
2630 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2631 of the record. The special value VAL_NONE in the bend_request means
2632 that no specific format was requested by the client. Documentation
2633 updated accordingly. Test server (ztest) will return a fixed dummy
2634 SUTRS record if your client requests SUTRS.
2636 Documentation updated accordingly.
2638 You can now set external libraries and RANLIB support in the top-level
2642 First public release.
