3 Make a number of functions defined in xmlquery.c static. These have
4 never been declared in a public header file (yaz/xmlquery.h) and was
5 made public by mistake.
7 Improve speed of character conversions (iconv utilities). This makes
8 conversions from MARC-8 faster.
10 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
11 unless type desired is "raw". This will prevent type "xml" from
12 returning ISO2709 .. Which obviously can not be XML parsed.
14 Fix memory leak in ZOOM that would occur if option apdulog was used
15 on a re-used connection.
17 Frontend server logs HTTP requests.
19 Frontend server now sends Z39.50 close when it times out (sesssion has
20 been idle for too long). Versions 2.0.30 and earlier also sent close.
21 But due to a mistake this was disabled in all versions after that, i.e.
22 the server would just close the socket immediately.
24 yaz-client emits a better message when receiving an unrecognised
27 Skip zero-length subfields when decoding ISO2709. This rare case happens
28 if a record has two FS characters in a sequence. Without this patch
29 there would be a reference beyond char array in using_code_len fragments
32 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
36 The show command offered by the zoomsh command now takes a 3d optional
37 parameter type which is what is passed to ZOOM_record. If the type
38 argument is omitted, "render" is used.
40 RPN to CQL conv may use USE string attributes (bug #2978).
42 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
46 Function yaz_xml2query allows a diagnostic element in the PQF XML
47 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
48 code and additional info respectively.
50 The BER BOOLEAN is now the integral type Odr_bool which still happens
51 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
52 typedef'd to Odr_int. This is still an integral 'int', but it may be
53 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
54 ASN-1 compiler as well as programs has been updated to use the new types.
58 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
59 only the bibliographic record was rendered. For type=opac, an OPAC
60 record is only returned if it is present.
62 iconv: small fix for encoding of advancegreek.
64 yaz-client: avoid double display of SRU/SRW records (bug #2798).
66 yaz-client: option auto_reconnect=on really reconnects.
68 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
70 server: avoid null ptr ref for for yaz_poll errors.
72 build: fix RPM build for RHEL 5.3.
74 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
78 Fixed bug #2709: TCP connect returns Invalid argument.
80 Fixed compilation for mingw.
82 Honor charset for raw records (ZOOM_record_get).
84 Fixed use of errno for threaded mode that was seen on Solaris 10.
86 Fixed argument passing with blanks in value for Windows Service.
88 Disable YAZ' own log rotate by default (no 1 GB limit).
89 The variable l_max_size which specifies the log file limit is set to 0
90 (DISABLED): This is due to the fact that YAZ is most often deployed using
91 logrotate. Also YAZ can not perform log rotate because of unsufficient
96 List supported encodings in man page for yaz-iconv.
98 Fixed missing SSL libs for --libs output
100 Re-established OID record syntax application-xml. Nobody should use it
101 but we don't want to change soname because of this symbol being absent.
103 --- 3.0.42 2009/02/02
105 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
107 Added member named_result_sets for init handler struct for the GFS. This
108 allows a server to disable named result sets.
110 Removed OID record syntax application-xml.
112 Added support for rule-based transliterator for ICU wrapper of YAZ.
114 Fixed bug #1902: yaz-icu XML output.
116 Make YAZ checks Emacs friendly.
118 BITSTRING value shows value. Bug #2346.
120 ISO2709 decoding: skip control characters from indicator data.
122 Omit sort key by default in yaz-icu's output.
124 Allow combined single char options (again) for YAZ' options function.
126 Utility yaz-marcdump got option to display YAZ version (-V).
128 Allow YAZ to use ICU 3.4.
130 Added new ICU test case which illustrates removal of diacritics.
132 --- 3.0.41 2008/12/29
134 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
136 --- 3.0.40 2008/12/29
138 For configure, using option --without-xml2 also disables Libxslt/Libexslt
141 Fixed bug #2352: yaz-marcdump crashes for certain record.
143 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
145 Added support for Danmarc2 to UTF-8 conversion.
147 Added support for ISO5426 to UTF-8 conversion.
149 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
150 implementation version.
152 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
154 --- 3.0.38 2008/11/10
156 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
157 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
159 ZOOM C now interprets databaseName option for ZOOM connection as path
162 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
164 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
166 Dummy Libxml2 types no longer defined in headers of YAZ'.
168 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
171 --- 3.0.36 2008/09/26
173 Various ODR chapter fixes.
175 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
177 Added missing source for Windows compilation, mutex.c.
179 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
181 For SRU connections in ZOOM all records up to "count" are now fetched.
183 Fixed crash in generic frontend server (and yaz-ztest) which occurred
184 in Windows due to bad error handling for Libxml2.
186 Added facility for sending arbitrary records (ASN.1 any) using
187 ZOOM C's Extended service update. Patch by Sam Reynolds.
189 New options for ZOOM C's connection, logapdu which makes ZOOM log
192 --- 3.0.34 2008/06/18
194 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
196 --- 3.0.32 2008/06/12
198 Fixed memory violation that could occur when decoding UTF-8. This bug
199 was only present in 3.0.30 of YAZ.
201 --- 3.0.30 2008/06/06
203 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
204 GNU TLS is used by default (if found).
206 yaz-ztest returns OPAC records if a client asks for OPAC.
208 Improved speed of MARC-8 encoding.
210 Added support for lossy and loss-less MARC-8 encoding.
212 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
214 Added new Windows Service wrapper (sc).
216 yaz-client's itemorder command may now send a file.
218 Fixed yaz-marcdump to allow the use of NS prefix for record element.
220 Added new function yaz_log_xml_errors.
222 Allow (but warn) unknown XML attributes in MARCXML parsing.
224 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
226 The UTF-8 to MARC-8 conversion now uses a different set of characters
227 for Greek symbols. Bug #2120.
229 --- 3.0.26 2008/02/21
231 Added yaz_daemon (daemon.h).
233 Fixed bug #2068: pkg-config trouble
235 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
237 --- 3.0.24 2008/01/28
239 Document --with-xml2 option.
241 Added OPAC XML XSD (etc/opacxml.xsd).
243 Allow glob mask for name attribute in retrieval element for the
244 generic frontend server's retrieval facility.
246 Changed yaz_poll_poll to return yaz_poll_except for all returned events
247 except POLLIN/POLLOUT.
249 Fixed error handling in cs_listen. Bug #2037.
251 --- 3.0.22 2008/01/20
253 Fixed version in yaz/yaz-version.h.
255 Fixed bug #2027: Crash when closing connection.
257 Changed configure so that ICU support is only enabled if only ICU
258 and Libxml2 is available (because the ICU chain is XML based).
260 --- 3.0.20 2008/01/15
262 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
263 is built. Only this DLL depends on the ICU runtime.
265 yaz-ziffy is no longer part of YAZ. It is distributed separately by
266 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
268 Changed license of CCL module to 'Revised BSD'. After consultation with
269 remaining members of the original EUROPAGATE consortium, we are re-issuing
270 the CCL module without a separate license. The software was developed by
271 Index Data as part of a research project. The special license was included
272 to help feed usage information back to the project consortium to support
273 project evaluation. At this time, the project consortium has long-since
274 disbanded, and the majority of the original principals have retired. At the
275 same time, we have significantly modified the software during the following
276 years, to the point where very practically no original code remains. To
277 simplify re-use of the software, we have contacted those members of the
278 consortium who could be reached, and agreed to re-issue the module as a
279 proper part of the YAZ package.
281 Tcl scripts uses /usr/bin/tclsh as preferred shell.
283 CQL closer to being version 1.2 compliant. CQL also allows free-form
284 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
287 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
288 bug could make Extended services handling crash in the ZOOM layer. This
289 bug was only present in YAZ 3.0.18.
291 --- 3.0.18 2007/12/19
293 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
296 yaz-marcdump reads and writes collection wrapped records.
298 Handle OPAC for record conversion module.
300 Fixes for ICU wrapper.
302 Allow ICU libs to be controlled with --with-icu .
304 --- 3.0.16 2007/11/12
306 Added yaz_poll which is a wrapper for select/poll. When poll is available
307 and non-buggy, it is used, by yaz_poll . This allows more than 1024
308 sockets to be in use.
310 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
311 functionality through an XML based configuration (ICU chain). This system
312 is useful for search facilities such as Pazpar2 and Zebra that needs to
313 perform tokenization of indexed material. The ICU code in a separate
314 library libyaz3_icu.a.
316 Added HTTP tunnel facility for COMSTACK, bug #1752.
317 This is a facility that allows a Web proxy, such as squid, to tunnel
318 Z39.50 traffic. This facility is "transparent" to must applications
319 using YAZ. It's enabled by using pseudo transport connect: followed by
320 the proxy address, followed by command, then follwed by he regular
321 "virtual" addresss. For example,
322 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
324 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
326 --- 3.0.14 2007/09/21
328 Fixed bad memory reference in ZOOM_record - cuased by member not being
329 initialized. This was a problem only in YAZ 3.0.12.
331 Fixed bug in conversion from MARC to XML: Non-XML characters in control
332 fields were not removed.
334 Changed the way C code is generated from codetables.xml. Made a MARC-8
335 conversion trie for each characterSet section rather than codeTable.
336 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
337 of codetables.xml from Larry Dixson, LOC. Bug #1464.
339 --- 3.0.12 2007/09/12
341 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
342 from ZOOM_record_error).
344 ZOOM C function ZOOM_record_get returns record schema for type="schema".
346 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
348 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
350 Better SRW-to-Bib-1 diagnostic mapping.
352 ZOOM C and yaz-client announces SRU version 1.2 by default.
354 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
357 Fixed in yaz_sru_decode to allow other version than 1.1.
359 --- 3.0.10 2007/08/22
361 Added support for SRU scan for ZOOM.
363 Added support for the use of the older versions or Extended Service
364 Update in ZOOM. To faciliate this, an option "updateVersion" may be
365 set to the version , 1=first, 2=second, 3=third. The third version is
366 what ZOOM C has used so far. And that, obviously, is the default.
368 Added support for CCL queries in Z39.50 queries sent to the GFS (and
369 therefore in Zebra and in SimpleServer-based applications). The new
370 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
371 qualifier file used to transform incoming CCL queries into Type-1 RPN,
372 which is passed into the back-end search callback function.
374 Added support for HTTP Basic authentication in clients: the SRU/W
375 codec encodes the username/password elements of the PDU structure
376 appropriately, and these may be set using the "user" and "password"
377 options in ZOOM-C applications (the same options that are used for
378 Z39.50 authentication).
382 Fixed bug #1208: SSL appears to be broken in ZOOM.
384 Fixed bug #1206: Libxml2 include path weirdness.
386 Added oid_name_to_dotstring.
388 Allow elementSetName to be specified for ZOOM C record update.
390 Allow waitAction to be specified for ZOOM C based for Extended Services.
392 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
393 syntax OID. Bug introduced in YAZ 3 series.
395 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
399 Fixed bug #1157: yaz-client does not read .yazclientrc from current
400 directory. yaz-client now reads commands from file given by option -f
401 if specified; then tries to read .yazclientrc in current directory.
402 Failing that, it reads .yazclientrc from user's home directory.
404 Added support for correlationInfo Note and ID for Record Update via
407 Added yaz-client command querycharset which specifies character set for
408 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
409 (termListAndStartPoint).
411 Charset ISO5428:1984 is an alias for ISO5428-1984.
413 Implemented a way to perform scan in a result set using Z39.50. This
414 is achieved by attaching the result set name in the characterInfo
415 (type InternationalString) of OtherInformation in the Scan Request PDU.
416 The result set is identified in the otherinformation by the new OID:
417 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
418 This allows for scan in result set and faceted search . Zebra did some
419 of this in the APT term using attribute type 8 and value being result
420 set. Using the OtherInformation approach for this is cleaner and easier
421 to work with in proxies and the like. This facility can be used in
422 yaz-client using new command setscan which takes a result set as first
423 argument, start position (APT) as second.
425 Changed decoding of SRU XML packed records to deal with servers that
426 have recordData with XML data with multiple root nodes. Also make
427 comparison for recordPacking case insensitive. Again, one server
428 returns "XML" where others return "xml".
430 For SRU responses allow Content-Type application/xml as well as text/xml.
434 Fixed bug in character set conversion of BER strings. Bug introduced
439 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
441 For OID class, use oid_class consistently.
443 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
446 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
447 character set for bibliographic information interchange". By Giannis Kosmas.
449 Added documentation on new OID API.
453 Changes to generic frontend server interface: added new member
454 'query_charset' for bend_initrequest structure. A backend init handler
455 should set this member to its native character set for query terms.
456 When defined, the frontend server logic will announce this character set
457 to a client if the negotiationModel bit is set by the client. All server
458 implementors are encouraged to specify this. If a backend server does not
459 specify this a warning is issued using yaz_log(YLOG_WARN,..).
461 Added CCL utility to remove terms (stop words) from resulting RPN
462 tree. This is handled by functions with prefix ccl_stop_words_ .
464 New ZOOM C option, "rpnCharset", which allows client-side conversion of
465 terms in RPN queries.
467 Clean-up the CCL API. Moved some internal structures from ccl.h to
468 private header cclp.h. Changed ccl_parser_create so that a Bibset must
469 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
470 This is replaced by ccl_parser_find_str which takes a string instead.
472 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
473 libyaz.la is the core of YAZ except the generic frontend server and
474 does not depend on POSIX threads anymore. libyaz_server.la is the
475 generic frontend server facilities and uses POSIX thread functionality
476 if available. The libyaz.la no longer depends on POSIX threads because
477 the number of global structures is limited. NMEM no longer re-uses blocks
478 between threads ; it simply free's memory immediately but allocates in
479 "large" chunks as usual. We don't expect any performance penalties
480 because of this. The yaz_log system is still using a global log_level so
481 caution must be taken when modifying it with yaz_log_init_.. +
482 yaz_log_mask_str. This, however, should not cause any trouble because
483 these functions are called during initialization of application code
484 anyway. `yaz-config --libs server` returns libs for server applications;
485 `yaz-config --libs` returns libs for non-server applications.
487 New OID database - with public definitions in oid_db.h. Removed old OID
488 database including the head oid.h and definitions such as enum oid_value
489 and struct oident. The new OID database uses the same string names as
490 before but the 'protocol' is gone. There are now only two representations
491 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
492 converts from string to OID; functions with prefix yaz_oid_to_string
493 converts the other way.
495 Change to emit_term() in CQL-to-PQF query translation: when a term has
496 the /regexp relation modifier, do not process it for leading and
497 trailing "^" and "*", which have quite different meanings in regular
500 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
501 write handlers no longer carries a 'last' parameter. This will make
502 yaz_iconv flush "less" characters. A flush is performed by call to
503 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
505 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
506 removed, because function yaz_query_to_wrbuf does the same.
508 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
509 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
511 Deprecated MARC utility functions removed.
513 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
516 Branch split: YAZ_2_1_55_branch
518 --- 2.1.54 2007/03/16
520 Fix to ZOOM-C so that transparent reconnection is properly handled on
521 connections that are in asynchronous mode.
523 Fixed compilation on OpenBSD 4.0.
525 Large strings in GRS-1 records are now properly displayed in yaz-client.
527 Added character conversion support for "advancegreek"; based on patch from
530 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
531 sequence is met. Before the error was not set so it would be unknown.
533 Adjust yaz-marcdump MARC reader so that it skips until record separator
536 --- 2.1.52 2007/03/07
538 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
539 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
540 fd_set structure used as a bitmask for the FDs to be selected on.
542 Using ACX_PTHREAD macro to check for POSIX threads.
544 Fixed have-vsnprintf check.
546 --- 2.1.50 2007/02/23
548 Fixes for configure on BSD. Bug #900.
550 Added snprintf/vsnprintf wrappers for systems that don't have
551 limits (heavens forbid).
553 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
554 created before all previous tasks were completed and removed from the
555 task queue, the new task could be removed by a mistake.
557 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
559 Implemented pass-through CQL-to-PQF conversions. Bug #861.
561 Fixed bug #832: Problem with MARC/charset in yaz-client.
563 Fixed bug #668: save command line history for yaz-client.
565 Fixed bug #830: pkg-config support.
567 --- 2.1.48 2007/01/23
569 Extended ZOOM result set options with two options that may be read by
570 a client: resultSetStatus and presentStatus with values as specified for
572 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
574 Fixed bug #827: Using SSL fails on Debian etch.
576 Fixed bug #826: Weird looking chars for set of MARC records.
578 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
579 that is treated as an ItemOrder with itemRequest being an XML document
580 external. The value of "doc" is the content.
582 Extended the GFS search facility. New member of bend_search_rr
583 'estimated_hit_count' signals that hits is known to be an estmate
584 (higher or lower than real hit count). New member 'partial_resultset'
585 signals that the search was partial (hit count is lower or equal than
586 real hit count). For Z39.50, the information is stored in resultSetStatus
587 member of SearchResponse APDU. For SRU, the information is signalled
588 via SRU diagnostic 59: "Result set created with valid partial results
591 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
593 --- 2.1.46 2007/01/13
595 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
597 Added ZOOM_connection_peek_event.
599 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
600 the following new functions:
601 ZOOM_event_nonblock, ZOOM_connection_process,
602 ZOOM_connection_get_{socket,mask,timeout},
603 ZOOM_connection_fire_event_{timeout,socket}.
604 The existing blocking event handler, ZOOM_event, is a wrapper for the
605 + blocking ZOOM_event_sys_{poll,select}.
607 Implemented function ccl_xml_config which parses XML version of CCL
608 configuration (bug #798).
610 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
612 Added timings utility (yaz/timing.h)
614 --- 2.1.44 2007/01/03
616 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
619 Fixed bug #779: Rotation of apdu.log fails.
621 Fixed for character set conversions:
622 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
623 Honor G1 set in MARC-8 decoding.
625 --- 2.1.42 2006/12/17
627 Fixed bug #775: char conversion does not handle Alternative UTF-8
630 Implemented function yaz_marc_read_line which parses MARC line format
631 records. There is a wealth of formats out there. So far, this function
632 reads line records produced by yaz_marc_write_line.
634 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
635 more generic and easier to remember(!) options: -i format and -o format
636 which specifies input format and output format respectively - where
637 format is one of "marc", "marcxml", "line", "marcxchange".
639 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
640 does not print anything except warnings for records.
642 For yaz-marcdump, added support for MARC split into files (-s) with a given
645 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
646 spec, at http://www.loc.gov/standards/sru/record-update/
647 This has changed the binary layout of the following structs:
648 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
649 bend_update_rr . Patch by Ko van der Sloot.
651 Added GFS utility function bend_assoc_is_alive which returns 1 if
652 association is still alive (client is connected); 0 otherwise (client
653 closed connection). This allows busy servers to stop working for
656 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
657 been a separate piece of software. This version of ziffy has been modified
658 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
660 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
662 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
663 Client code may now interrogate options such as "init_opt_sort" to
664 find out whether the server claims to support various options.
666 --- 2.1.40 2006/11/27
668 Added utilities yaz_{set,get}_esn to set/get element set name from
671 Removed the build of libyazthread.la. The libyaz.so is the threaded version
672 of YAZ and has been so since YAZ 2.1.10.
674 Implemented ZOOM_record_error which returns error information for
675 record (surrogate diagnostic).
677 --- 2.1.38 2006/10/31
679 Updates for SRU Update by Ko van der Sloot:
680 1. Changed name from "operation" to "action"
681 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
682 versions in the code, marked as 'backward compatible'.
683 3. Added diagnostics for SRU Update.
685 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
687 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
689 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
691 For GFS, fixed problem with SRU diagnostic 'First record position out of
692 range' being issued for 0 hits.
694 zoomtst10 part of Windows Build.
696 --- 2.1.36 2006/10/13
698 Implemented yaz_filepath_comp which splits a path into file path
699 components (required by Zebra 2.0.3+).
701 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
702 BSD inspired license until now so this should not have any real impact on
703 anybody. See http://www.opensource.org/licenses/bsd-license.php
705 Fixed bug #687: Missing log lines.
707 Fixed bug #678: CQL to PQF translation does not preserve double-quote
710 Fixed bug #689: SRU diagnostics to be added.
712 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
713 whether a connection is idle (no more work do do).
715 --- 2.1.34 2006/10/04
717 Change type of optval from long to int for invocation of setsockopt with
718 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
720 Added support for specifying the max log file size for the Generic
721 Frontend Server. The size is given with option -r.
723 --- 2.1.32 2006/09/21
725 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
727 --- 2.1.30 2006/09/17
729 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
732 Fixed bug in Generic Frontend Server that could cause a server to stop
733 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
735 For the generic frontend server, the maximum record size is used as maximum
736 size of incoming packages (SRU + Z39.50). The value until was previously
737 only used in Z39.50 Init negotiation and, later, in a session controlled
738 sizes of records returned. This is controlled using -k option. It can be
739 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
741 --- 2.1.28 2006/09/04
743 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
746 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
748 New option for yaz-marcdump -lpos=value which allows setting a portion
749 of MARC header to a certain value.
751 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
753 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
754 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
756 --- 2.1.26 2006/08/15
758 Fixed problem with SRU mode type (soap, get, post) for yaz-client
761 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
763 --- 2.1.24 2006/08/08
765 Fixed MARC ISO2709 encoding routines to deal with character set
768 Minor changes to GFS logging. Database included in search request log
771 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
772 cached/multiple records.
774 Shared libraries are built by default on Unix+configure.
776 Changed cql2pqf transformation to use a different evaluation order. The
777 new order is: always, relation, structure, position, truncation, index
778 and relationModifier. Old order was: always, relation, relationModifier,
779 structure, index, position, truncation. Note that the the latter ones
780 override former ones for identical attributes.. The new scheme means that
781 it is possible to override any existing attribute with a relationModifier.
782 And also that it is possible to override everything for the index rule
783 (except the ones listed in relationModifier). No order is perfect but this
784 one, we believe, covers more real cases.. The "always" should have been
785 called "default", since the attributes there can be overridden with all
788 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
789 compilation phase, but also for yaz-config --cflags output. This allows
790 us to have public headers with Libxml2 stuff in them . It should also,
791 eventually, make Libxml2 checks redundant in packages using YAZ, such
794 --- 2.1.22 2006/06/15
796 Changed SRU update structure bend_update_rr so that SRU diagnostics are
797 stored in uri, message and details.. Previously diagnostics were stored
798 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
799 compatibility.. but he's probably the only one affected, so.
801 Added support for CCL, compiled on the client side, in ZOOM-C. This
802 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
803 input; the resulting query objects can be used for for searching with
804 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
806 YAZ' configure searches for OpenSSL by default.
808 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
809 SL_CTX_use_certificate_file. See
810 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
811 for more info. Thanks to Ko van der Sloot.
813 --- 2.1.20 2006/06/02
815 Bug #600: SRU GET, POST support for yaz-client. Introduced
816 command 'sru' which selects method SOAP/GET/POST.
818 Allow missingValueAction to be specified for the sortspec string -
819 function yaz_sort_spec. By default, the missing value action is null.
820 Use ! to specify "abort". Use = followed by stringvalue to specify default
823 Ensured that Present-handler (if defined) is called in GFS before any call to
824 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
825 searchRetrieve requests.
827 Documentation for YAZ is now based on the Docbook XML/XSLT using
828 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
829 is no longer depending on jade/openjade or docbook-to-man scripts.
830 PDF is no longer part of the distribution - but can optionally be
831 made using DSSSL/jadetex or FOP.
833 Added retrieval handling support in Generic Frontend Server to support
834 conversion between MARC/XML as well as XSLTtransforms. See
835 etc/yazgfs.xml for an example.
837 Added Authentication support to Generic Frontend Server in SRU
838 mode. Authentication using HTTP Basic is supported, as is the use
839 of 'x-username' and 'x-password' parameters in the request itself.
841 Added support for a new character set MARC8s identical to MARC8 except
842 that it converts combined characters to single Unicode characters in the
843 Latin-1 range (when possible).
845 --- 2.1.18 2006/04/24
847 ASN.1 compiler 0.4: generates brief Doxygen file header for
848 generated .h/.c files.
850 Utility yaz_iconv now supports conversion to MARC-8.
852 New facilities for the MARC module. The reading - and writing of
853 content are separate methods for the yaz_marc_t handle. The following
854 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
855 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
856 format). Write functions have prefix yaz_marc_write_.. The existing
857 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
858 available. Removed support for OAI-MARC and simplexml (not the
859 simplexml from PHP5).
861 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
862 to be returned for this connection.
864 --- 2.1.16 2006/03/31
866 Allow multiple languages and charsets to be specified with
867 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
868 negcharset iso-8859-1,utf-8
870 Translation of proximity nodes from CQL into PQF now works.
872 Moved to automake 1.8, 1.9.
874 Added function yaz_log_set_handler which allows a log handler to be
875 installed. This handler will be called for all log messages. Output
876 to file is also produced; but that can be disabled by passing NULL
877 fname to yaz_log_init_file.
879 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
881 For SRW (including GFS), accept application/soap+xml as content-type
884 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
885 produces NO stylesheet reference even if a default stylesheet is specified
888 --- 2.1.14 2006/03/14
890 Updated Windows package to include yazd.dll + yazd.lib for the
891 Development component.
893 If the environment variable YAZ_LOG is set, then it is used as a
894 string indicating the default level of logging to use if not
895 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
896 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
897 used as before. So, for example, to omit warnings from YAZ logging,
900 cql_transform() now map structure and other attributes before indexes,
901 so that index-specific structures and other attributes can override
902 defaults. So now a combination of mapping specifications such as:
904 index.dc.date = 1=date-modified 4=5
905 does the right thing.
907 cql_transform() now also respects the "always" mapping specification,
908 which establishes an initial set of attributes to be used for all
909 terms except where overridden by more specific attributes associated
910 with the index, relation or modifier.
912 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
913 which mode to use; one of "post", "get" or "soap" (SRW, default).
915 Fixes for yaz_iconv routines: changed trie-based character set conversions
916 to use only non-negative values for bit fields due to Sun's C compiler not
917 supporting negative values.
919 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
920 sequences where not read correctly. Fix by Rustam Usmanov.
922 Updated win/makefile to use options, settings which makes things
923 compile with VS C 2005.
925 --- 2.1.12 2006/02/01
927 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
929 In ZOOM socket code, use select instead of poll on MacOSX.
931 ZOOM-C now support client-side compilation of CQL into RPN that is
932 sent to the server, enabling CQL to be used against all Z39.50
933 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
934 ZOOM_query object, and submit it using ZOOM_connection_search().
935 The CQL-to-RPN translation uses a configuration file, the name of
936 which must be specified in the Connection's "cqlfile" option.
938 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
939 function, which takes as its start-term parameter a ZOOM_query object
940 (which may have had either CQL or RPN set into it).
943 --- 2.1.10 2005/11/29
945 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
946 GFS to support this as well. Backend handler, bend_srw_update, does the
947 update work. Code contributed by Ko van der Sloot.
949 Allow retrieval of Search Result-1 information in ZOOM by the use of
950 options that are attached to a result set. ZOOM documentation updated
953 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
954 UTF-8 conversion. Patch by Raj Patel.
956 Added option -m to GFS to control formatting of timestamps in log file.
958 Added 'exit' as synonym for 'quit' in yaz-client
960 Added support for specifying SRW resultSetId + resultSetIdleTime in a
961 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
962 for the new members. Patch by Ko van der Sloot.
964 Added support for SRU POST. It is supported for content-type
965 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
967 Do not build the separate Multi-threaded (MT) library libyazthread.la.
968 Instead make the library libyaz.la multi-threaded. Threading as a whole
969 can still be disabled by configure option --disable-threads. Previosly,
970 with older GLIBCs there were problems with MT libs under Apache. This
971 has now been fixed a long time ago.
973 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
976 CQL module modified to be case insensitive for relations/indexes/operations.
978 Fixed bug in CQL transform code: incorrect value relationModifieder
981 Added 'show all' command for yaz-client which retrieves all results
984 Added new yaz-client, xmles, which takes a (private) OID and
985 a document to be sent as an extended service request.
987 Describe new yaz-client commands wait_response and set_auto_wait.
989 Increase TCP/IP listener backlog from 3 (which I am guessing was
990 copied from the SunOS manual entry way back when) so SOMAXCONN, so
991 that the socket will queue as many incoming connections as it's able
992 to handle ongoing connections. In other words, it will never now
993 refuse a connection that it would be able to handle merely because
994 it's not got around to accepting() enough of the pending connections
995 yet. This is the behaviour anyway under Linux, where the listen()
996 argument is ignored; but not under BSD and on systems such as
997 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
998 YAZ-based servers should now be uniform across operating systems in
1001 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1002 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1003 This allows yaz-marcdump to read large MARC batches (>2 GB).
1005 Modified all YAZ source files - except the source which is auto-generated
1006 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1009 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1010 corresponding to the existing *_setl() function. These allow option
1011 values containing arbitrary valuues.
1013 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1014 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1015 except that it returns an indicator of whether or not the sort
1016 criterion was accepted (0 for OK, -1 for invalid).
1018 --- 2.1.8 2005/06/07
1020 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1021 MARC output rather than returning "new" buffer.
1023 yaz-client warns about unknown init options.
1025 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1027 --- 2.1.6 2005/05/24
1029 Added support for SRW sort in Generic Frontend Server. Patch
1030 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1031 sortKeys - or NULL if none is provided.
1033 Fixed bug #307: It was impossible to specify indefinite/no timeout
1034 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1037 Added support for multiple languages and charsets to be specified in
1038 ZOOM. Each charset/language is separated by a blank. If negotiation is
1039 in effect in init-response, Option
1040 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1041 Code based on patch by Vasiliy Osadchuk.
1043 Fixed bug #306: infinite recursion that occurred when calling
1044 yaz_log_level_init as the first call (before other log level or
1047 Fixed bug in scan handling in front end server: if preferred-Position-In-
1048 Response was non-present, a NULL pointer referece was performed.
1050 --- 2.1.4 2005/04/26
1052 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1053 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1054 now defined for all those error codes. So instead of putting 109 in
1055 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1056 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1058 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1061 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1063 Program yaz-client now exits and produces an error message if multiple
1064 Z39.50 servers are specified on the command line (none or one allowed
1067 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1070 --- 2.1.2 2005/03/16
1072 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1074 Fixed bug #272: Preserve spacing for CCL terms.
1076 --- 2.1.0 2005/03/14
1078 Added support for virtual hosts and multiple backend servers for
1079 the YAZ frontend server. The configution is XML based and
1080 support specificition of CQL to RPN mappings and explain information.
1081 See section "Virtual Hosts" in the YAZ manual.
1083 Extended OPAC display utility. OPAC display utility renders
1084 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1085 to supplement yaz_marc_decode_wrbuf.
1087 Fixed a bug in MARC decoder that could caused it to crash for some
1088 invalid MARC records. More diagnostics and warnings where added in
1089 XML output (warnings, etc are stored in comments).
1091 --- 2.0.34 2005/02/08
1093 Fixes for UNIX domain sockets. Bug #261.
1095 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1097 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1098 Added yaz_marc_subfield_str which defines subfield lead string which is
1099 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1100 yaz_marc_endline_str which defines end of fields string used in
1101 YAZ_MARC_LINE format. Default string is newline.
1103 Experimental support for MarcXChange. This format can be produced
1104 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1105 http://www.bs.dk/standards/MarcXchange.xsd
1107 Added yaz-client commands scansize that sets maximum number of
1108 entries to be returned by scan.
1110 --- 2.0.32 2005/01/11
1112 Added support for SRW scan in yaz-client and Generic Frontend Server.
1114 * Added whereInList member to SRW Scan Term.
1116 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1118 Fixed NMEM system to return aligned blocks on the smallest boundaries
1119 that are suitably aligned for all possible types on the particular
1120 architecture YAZ is being built for.
1122 --- 2.0.30 2005/01/04
1124 Fixed numerious warnings that was issued with newer versions of GCC.
1126 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1127 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1130 Make YAZ Generic Frontend Server slightly faster.
1132 Enhance (and reduce) logging for Generic Frontend Server.
1134 Revert YAZ log system so that it flushes every write operation
1135 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1137 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1138 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1139 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1140 will effectively disable old definitions.
1142 --- 2.0.28 2004/11/09
1144 Added yaz_log_time_format which specifies log format using
1147 Added yaz_log_module_level which returns mask for a module. Value
1148 is non-zero mask a if module is enabled; zero if disabled.
1150 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1151 in include/yaz/cql.h.
1153 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1155 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1157 Fixed bug #172: RPM builds does not enable SSL.
1159 Doxyfile.in part of dist. Doxyfile generated by configure.
1161 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1162 are given and the corresponding component does not exist.
1164 Extend CCL documentation in YAZ reference. Describe r=r.
1166 --- 2.0.26 2004/10/01
1168 Fixed MARC->MARCXML conversion to properly deal with
1169 fields, subfields, indicators having non-ASCII characters.
1171 Fixed MARC->MARCXML conversion so that ASCII control characters
1172 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1175 Added YAZ GFS support for conversion from Z39.50 surrogate
1176 diagnostics to SRW surrogate diagnostics.
1178 Bug fix: YAZ GFS did not return schema in explainResponse.
1180 --- 2.0.25 2004/09/30
1182 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1183 now converts recordSchema to elementSetName as well as schema URI.
1185 Fixed bug in COMSTACK that prevented HTTP request packages from being
1188 --- 2.0.24 2004/09/29
1190 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1191 does not require white-space before and after the dash in a range, e.g.
1192 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1195 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1196 due to new GCC removing "redundant" code.
1198 Added yaz-client commands scanpos and scanstep that sets preferred
1199 position and step-size for scan.
1201 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1203 Added CCL utility ccl_qual_buf which parses one or more CCL
1204 spec lines in a buffer.
1206 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1207 of name and value - ignoring empty lines and comments.
1209 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1211 Added odr_get_element_path which returns current element path for an
1212 ODR handle. This utility is useful in error handling or user-defined
1215 Added ODR_PRINT utility odr_set_stream which is is a more generic
1216 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1217 to a write function and pointer to close function. The close function - if
1218 non-NULL - will be called during odr_destroy.
1220 Fixed bug in CCL parser where truncation char was not removed from
1221 right side when truncation=both was in effect.
1223 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1226 --- 2.0.23 2004/08/11
1228 Fix buffer overrun in CQL parser when dealing with proximity (%).
1230 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1231 to UTF-8/UCS conversion is now only based on codetables.xml.
1233 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1235 --- 2.0.22 2004/08/06
1237 Add support for more "commit changes" in ZOOM (uses Extended Services).
1239 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1242 Yet another small fix for configure of SSL.
1244 --- 2.0.21 2004/05/14
1246 Fix SSL libs for configure when --with-openssl=DIR is given.
1248 --- 2.0.20 2004/05/10
1250 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1252 SSL comstack now uses yaz.pem certificate file on server side
1253 by default. Certificate filename can be configured by calling
1254 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1256 Fix bug regarding multiple calls to ZOOM_connection_connect.
1258 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1260 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1261 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1263 ZOOM now allows inspection of X509 peer certificate for verification.
1264 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1266 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1267 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1268 as "modular" but it simplifies things.
1270 Added cs_get_peer_certificate to that returns peer X509 PEM.
1272 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1273 NULL if SSL is unavailable.
1275 Documentation about MARC decoding tools.
1277 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1279 --- 2.0.19 2004/03/30
1281 Rename CHANGELOG to NEWS to follow GNU style packing.
1283 Fix bug with missing initialization of member in init_diagnostics.
1284 This bug affects threaded version of GFS server.
1286 --- 2.0.18 2004/03/20
1288 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1291 Ensure zlib.dll is packed with Windows install.
1293 --- 2.0.17 2004/03/17
1295 Fix encoding of xsd:string to use text instead of CDATA.
1297 Fix endless loop in CQL parser with unbalanced ".
1299 Use a more compact way to store MARC-8 conversion tables.
1301 --- 2.0.16 2004/03/16 Debian only
1303 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1306 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1311 --- 2.0.15 2004/03/01
1313 Another fix for decoding of XML packed records.
1315 --- 2.0.14 2004/02/25
1317 Fixes for Chunked encoding. White space not ignored after length spec.
1319 Update NS and use default NS for SRW diagnostic elements.
1321 --- 2.0.13 2004/02/23
1323 Implement ZOOM_resultset_cache_reset which resets record cache.
1325 Implement ZOOM_resultset_sort which sorts a result set.
1327 Implement chunked HTTP transfer.
1329 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1331 --- 2.0.12 2004/02/16
1333 Added member 'schema' to bend_explain_rr structure so that backend
1334 can specify explain record identifier. Defaults to Zeerex 2.0.
1336 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1338 --- 2.0.11 2004/02/16
1340 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1343 Added init command for yaz-client which sends "extra" init request.
1345 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1346 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1348 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1350 Make ZOOM error code for "invalid query".
1352 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1354 --- 2.0.10 2004/02/05
1356 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1359 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1361 Added option -p <file> to make Generic Frontend Server to write PID file.
1363 Added option -D to put Generic Frontend Server in background on its own.
1365 Make ZOOM C recognize option "password". If unset, "pass" is used
1366 (for backwards compatibility).
1368 Fixed a bug in Generic Frontend Server that could make it crash if a
1369 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1372 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1373 Must be issued before open, in order to be in effect.
1375 --- 2.0.9-6 2004/01/12 Debian/Windows
1377 Make the SRU server more picky WRT unknown params, etc.
1379 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1381 New YAZ client command, options, that sets Z39.50 options.
1383 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1384 options from a string of tokens (one token for each option bit).
1386 Update SRW diagnostic code messages.
1388 --- 2.0.9-5 2004/01/07 Debian/Windows
1390 Handle user defined stylesheet for SRW/SRU.
1392 --- 2.0.9-4 2004/01/06 Debian/Windows
1394 Fix bug in decoding of Content-Length.
1396 --- 2.0.9-3 2004/01/06 Debian/Windows
1398 Fix a bug with decoding of XML packed records.
1400 --- 2.0.9-2 2004/01/05 Debian only
1402 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1404 Fix bug in SRW/SRU diagnostics decoding.
1406 --- 2.0.9 2004/01/05
1408 Fixed bug in Generic Frontend Server which could drop records exceeding
1409 preferred message size. Reported and fixed by Irina Dijour.
1411 Fixed calculation of package size for structured records in Generic
1412 Frontend Server. Reported and fixed by Irina Dijour.
1414 Fixed namespace for SRW/SRU diagnostics.
1416 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1418 --- 2.0.8 2003/12/22
1420 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1421 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1424 CQL changes to reflect recent changes to the specification:
1425 * Documentation talks about context sets instead of index sets.
1426 * Documentation talks about indexes instead of qualifiers.
1427 * The CQL-to-PQF transformer's configuration file now uses
1428 "index.set.name = <attributes>" instead of the old form
1429 "qualifier.set.name = <attributes>". (Both forms are still
1430 understood but the latter is deprecated.)
1431 * CQL terms with no explicit index specified are now interpreted as
1432 cql.serverChoice instead of srw.serverChoice (which of course
1433 behaves exactly the same.)
1435 --- 2.0.7 2003/12/16
1437 MARC conversion can now generate ISO2709 output in another
1438 character set. yaz-marcdump uses this facility if you invoke it
1441 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1442 functions from there can be used from C++.
1444 --- 2.0.6 2003/12/04
1446 Frontend server now transfers memory from decoded packages to stream
1449 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1450 references to show up.
1452 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1453 the ZOOM Abstract API. The older names for the same options are still
1454 also supported for the benefit of old applications.
1456 ZOOM-C supports "implementationId" and "implementationVersion" options
1457 to go along with "implementationName". These allow the user code to
1458 specify identification strings to be sent to servers.
1459 Add OID for the new ExtLite attribute set.
1461 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1462 as requested/supplid by Ere Maijala <ere@atp.fi>
1464 For generic frontend server, reverse the order of
1465 "toolkit-supplied / application-supplied" strings sent as implementationId,
1466 Name and Version. Also, remove the spaces around the slash. This brings
1467 the GFS in line with the behaviour of ZOOM-C on the client side.
1469 Add function ZOOM_scanset_display_term.
1471 yaz-client shows scan displayTerm if present.
1473 Utility yaz-iconv is now installed by default along with the man page
1476 Extend configure check for OpenSSL to use pkg-config where available (such
1479 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1480 server to specify uid/gid/mask for socket using the format
1481 unix:[user=uid,][group=gid,][umask=mask,]file=path
1482 If file= is omitted the existing format is assumed, e.g.
1484 in which case the mask is 0666 (rw for everybody).
1486 Major restructure of YAZ source. All source in libyaz is in src directory.
1487 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1488 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1490 Added man page for utility yaz-marcdump (used to be called marcdump).
1491 yaz-marcdump is installed by 'make install'.
1493 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1494 of incoming package failed.
1496 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1498 Change prototype of odr_perror: add const to message string.
1500 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1502 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1503 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1504 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1505 DNS lookup. There should not be any compatibility problems with this
1506 assuming that blocking=1 or 0 is used.
1508 Fix bad reference in UNIX comstack in function cs_addrstr.
1510 Fix for compilation on AIX.
1512 The generic front-end server (server/seshigh.c) now supports returning
1513 Init diagnostics to the client in User-information-field, in
1514 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1517 --- 2.0.4 2003/09/04
1519 Allow any CQL relation (not just all,any,exact,scr).
1521 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1522 that features the same UI.
1524 Implemented command update0 in YAZ client which is equivalent to
1525 update but uses old of Ext Update ASN.1.
1527 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1528 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1529 Previously no OID was used for this info.
1531 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1532 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1533 returns 'malformed search term' otherwise.
1535 SortResponse member resultCount now set to NULL in sort handler of
1538 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1541 Add three new utility functions for translating OIDs between various
1542 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1543 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1544 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1545 char *oid_to_dotstring(const int *oid, char *oidbuf);
1546 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1548 Reverted modifications for ES Update definition for z_IU0Update
1549 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1550 is back to YAZ 2.0.2.
1552 String value attributes for CCL parser.
1554 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1555 which their FirstSearch server returns in Init responses, sometimes
1556 carrying useful diagnostic information when Init fails. This has the
1557 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1558 "z39.50/oclcui.asn", where its definition is somewhat different from
1559 what OCLC document on their web-site, as required to interoperate with
1562 Support for anonymous authentication in yaz-client. Use the command
1565 * Fix the OID of the Index Data-local "admin" Extended Service from
1566 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1567 the 1000, which indicates a locally-defined OID, was a mistake.
1569 --- 2.0.3 2003/06/20
1571 Fix CCL directive @case handling so that it affects string match for
1572 both CCL keywords and qualifiers.
1574 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1575 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1576 Decoder has been updated with ASN.1 changes as listed in
1577 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1578 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1579 z_IUUpdate, remains unchanged.
1581 ZOOM_record_get may now return a record in a specific character set.
1582 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1583 "from" is the character set of record as returned by target. "to" is
1584 the character set to be returned. If omitted, "to" is UTF-8.
1586 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1588 New ODR utility, odr_getelement, which returns name of element for
1589 which encoding/decoding failed.
1591 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1592 in cases where a required element was omitted.
1594 Bug fix: some MARC8 sequences were not converted.
1596 New ZOOM option "step" which specifies number of records to be
1597 retrieved in one chunk. Used in conjunction with "start" and "count".
1599 SRW support for yaz-client. Use scheme http: to use it, e.g.
1602 yaz-client no longer does (un)intelligent character set conversions
1603 by default. Can be enabled with charset and marc_charset commands.
1605 xmalloc trace fix for 64-bit systems such as DEC alpha.
1607 Solaris 2.6 compile fix.
1609 New function, cql_strerror() translates SRW error codes, as returned
1610 by cql_transform_error(), into human-readable English strings. Used
1611 in yaz-client diagnostics when appropriate.
1613 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1614 converts it into a type-1 query which is sent to the server. This
1615 makes CQL available for use with all Z-servers, as opposed to the tiny
1616 minority that can handle CQL queries themselves.
1618 --- 2.0.2 2003/04/28
1620 New Debian package layout similar to the Redhat Package layout.
1622 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1623 and search result respectively.
1625 --- 2.0.1 2003/04/25
1627 Redhat package is now several packages: libyaz (runtime libraries),
1628 libyaz-devel (development and documentation, and yaz (utility programs).
1629 Package spec file by Morten Bogeskov.
1631 New member 'schema' in struct bend_fetch_rr which the name of requested
1632 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1633 handler MAY set this to reflect the schema of the returned record.
1635 New member 'display_term' in struct scan_entry. GFS now sets member entries
1636 and allocates scan entries to be filled by user scan handler. In previous
1637 version, entries member was allocated by the scan handler. That still works,
1638 but the GFS will ignore member display_term - assuming it was NOT set by
1639 the handler. The fact that the GFS now allocates the entries both allows
1640 for new members and makes a scan handler easier to write.
1642 Fix CQL lex buffer overflow.
1644 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1645 SRU default recordPacking is string.
1647 SRU protocol support for frontend server.
1649 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1651 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1653 Added scan for the ZOOM shell (zoomsh).
1657 * String Identifers for Schemas (Amendment 5).
1658 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1659 Old definition for schema
1660 Odr_oid *schema; /* OPT */
1665 Z_InternationalString *uri;
1666 #define Z_Schema_oid 1
1667 #define Z_Schema_uri 2
1670 * resultCount parameter to Sort Response (Amendment 1).
1671 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1673 Support for SRW 1.0 over HTTP. This is an optional feature and
1674 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1677 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1678 on the same port. SRW SearchRetrieveRequests are mapped
1679 to bend_init,bend_search,bend_fetch,bend_close.
1681 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1683 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1684 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1686 ZOOM connections are SRW based if schem http is used for hostname
1687 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1688 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1690 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1691 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1692 distance=n, order=true/false, relation=le, prox unit=word. If
1693 n is omitted, distance 1 is used.
1695 Fixed problem with C compiler include path in wrong order.
1697 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1698 on Solaris. Patch from Ko van der Sloot.
1700 New MARC decode API. All new functions operate on a yaz_marc_t
1701 handle. The most important new functions are: yaz_marc_create,
1702 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1703 decode and destroy respectively. Decoder can produce formats
1704 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1705 include/yaz/marcdisp.h.
1707 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1708 to UTF-8, UCS-32, wchar_t or Latin-1.
1710 * Prototypes for yaz_iconv_-functions moved to separate header
1711 include/yaz/yaz-iconv.h.
1713 Make a few private functions 'static' in unix.c. This prevents
1714 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1716 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1717 are set when Init Response is received.
1719 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1720 but returns diagnostic set as well.
1722 New function yaz_strerror which is a portable wrapper for
1723 strerror/strerror_r/GetLastMessage.
1725 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1726 is returned for MARC. If type is "oai", then OAI MARC is returned.
1728 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1731 --- 1.9.2 2002/11/26
1733 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1735 Fix bad race conditions on SIGTERM and terminate gracefully in
1738 Move retrieval (data1) module to Zebra since nobody seems to be
1741 Add GRS-1 render for ZOOM using same format as yaz-client.
1743 --- 1.9.1 2002/10/05
1745 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1747 Fix broken ESpec handling in data1 module.
1749 SGML reader parses comments and makes them part of the data1 tree.
1751 Added several type casts so that YAZ compiles as C++ code.
1753 ZOOM didn't handle PDU encoding failures properly.
1755 Added more Bib-1 diagnostics (approved extensions).
1757 GNU configure: better check for iconv.
1759 More portable use of accept, getpeername. Check for socklen_t. Use
1760 int/size_t if socklen_t is not defined.
1764 PQF parser rejects bad queries - including those with extra
1765 characters in them. PQF parser used to silently ignore that.
1766 Cleaner API for PQF added, which allows you to get detailed
1767 error information for bad queries (see yaz/pquery.h).
1769 Fixed bug in ZOOM_record_get for type "database".
1771 Implemented mini iconv library supporting conversions between
1772 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1774 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1776 --- 1.8.9 2002/08/20
1778 Fixed ZOOM C record cache so that preferredRecordSyntax and
1779 elementSetName is used to check for already fetched records.
1781 --- 1.8.8 2002/08/02
1783 Added three members in bend_initrequest structure to facilitate
1784 character set negotiation.
1786 Fixed a bug in frontend server that could cause indefinite
1787 loops under rare conditions.
1789 Revised character set utilities (charneg.h) so that encoding
1790 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1792 For PQF, directive @term <type> sets term type for Scan/Search.
1793 Here <type> is general, string, numeric, null. The term type
1794 is inherited - just like @attr.
1796 New call odr_set_charset that sets character set conversion for
1797 international-strings on a ODR stream. Prototype is:
1798 int odr_set_charset(ODR o, const char *to, const char *from);
1799 The InternationalString is still represented as C string in YAZ
1800 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1801 won't). On the protocol level, you can use any encoding.
1803 Support for UNIX sockets in ZOOM.
1805 Solaris recv sometimes returns errno == ENOENT. It is treated as
1806 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1808 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1809 both client and server. Code by Morten Bogeskov.
1811 --- 1.8.7 2002/05/22
1813 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1814 that they can be used directly from Visual Basic. You must recompile
1815 your windows APP if you're using ZOOM.
1817 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1818 Commands "lang" and "charset" sets language and character set respectively.
1819 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1820 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1822 Attributes from multiple CCL fields may be OR'ed rather than merged
1823 using directive "@field or". Fields are still merged by default -
1824 equivalent to "@field merge".
1826 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1829 Fixed bug in zget for parameter ExtendedServicesResponse.
1833 --- 1.8.6 2002/03/25
1835 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1837 Client displays USR.1:SearchResult-1 (hits per term).
1839 Additional Search Info for search in Generic Frontend Server.
1841 Fixed CCL parsing of "field=s".
1843 WIN32 installer - using the excellent NSIS software from nullsoft.
1845 Fixed CCL parsing of "field = - <number>".
1847 Added function yaz_marc_decode that decodes MARC for line mode
1848 display or XML (similar to that used by JZKit).
1850 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1851 Z39.50. But ISO/ILL was, however.
1853 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1854 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1859 --- 1.8.5 2002/02/03
1861 New YAZ client features: Command completion and new commands:
1862 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1863 Code provided by Jacob Poulsen.
1865 New call oid_trav, that visits all registered OIDs via callback.
1867 Function ZOOM_record_get now returns const char pointer rather than
1868 void pointer. It saves a lot of type casts.
1870 For YAZ client, command "auth" now allows you to set authentication
1871 in IdPass style. It is enabled when three tokens are given - order
1872 is user, group and password.
1874 Fix memory leaks in MARC record handling for ZOOM.
1876 New option for YAZ client, -k <kilobytes> that sets
1877 maximum record size. Similar to -k option for generic frontend
1878 server and yaz-ztest.
1880 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1882 Prefix query parser reports "fail" when bad attribute set is given.
1884 Fix in MARC decoder. Proximity logging. Fix for attribute set
1885 in scan handler for server. Patches by Shigeru Ishida.
1887 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1890 Configure option --with-openssl=<dir> now works when a directory is
1891 specified. Patch provided by Morten Bogeskov.
1893 New option for YAZ client, -u <auth>, that sets authentication.
1895 ZOOM fix: error information was sometimes "missing", since error
1896 was cleared/reset too when it shouldn't.
1898 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1900 --- 1.8.4 2002/01/04
1902 Scan for ZOOM API. New object ZOOM_scanset. New functions
1903 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1904 ZOOM_scanset_destroy.
1906 New ZOOM function, ZOOM_connection_last_event, that returns type
1907 of last event (such as "receive data", "send data", "apdu received",
1910 New ZOOM option, schema, that specifies schema for retrieval.
1912 New CCL feature. Qualifiers can be aliases for one or more
1913 other qualifiers (if more than one is given, OR is used).
1915 ZOOM uses named result sets if target supports it.
1917 Two new YAZ client commands: . (dot, which sources a script of YAZ
1918 client commands), and ! (to execute shell command.). Implemented
1921 Working on Debian packages.
1923 --- 1.8.3 2001/11/19
1925 YAZ client enables named result sets only if target supports it.
1927 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1929 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1930 with key="host" to get same result.
1932 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1933 Function Z3950_resultset_record(s) returns references to records
1934 "owned" by resultset. To become owner use Z3950_record_clone.
1936 Function z_ext_record handles Extended Services. Thanks to
1939 --- 1.8.2 2001/11/12
1941 CCL Parser fix: ignore token comma when dealing with and-lists.
1943 Documentation updates for COMSTACK.
1945 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1946 Changed prototype Z3950_records. For some functions, int parameters
1947 were changed to size_t.
1949 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1952 New MARC decode/display function, marc_display_exl, which properly rejects
1953 non-ISO2709 records. YAZ client uses it.
1955 --- 1.8.1 2001/10/29
1957 Fix bug: local attribute set wasn't set correctly in PQF strings.
1961 * Old Z39.50 codecs no longer supported.
1963 Added ZOOM C binding. See http://zoom.z3950.org/
1965 Renamed states for COMSTACKs to avoid confusion with events.
1967 Implemented cs_look and proper cs_rcvconnect.
1969 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1971 Configure detects POSIX threads on OpenBSD.
1973 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1974 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1976 When error is returned from present handler, non-surrogate diagnostic
1977 is returned in present response (and fetch handler is no longer called).
1979 * Minor adjustments to pquery parser (PQF). Token characters may be
1980 escaped by using backslash (C-style).
1982 PQF parser allows string attribute values to be specified. For @attr,
1983 non-numeric characters after the equal-sign are treated as strings
1984 (e.g. @attr 9=title).
1986 CCL trunction character may be defined (@truncation in file)
1988 * function zget_ExtendedServicesRequest sets waitAction to
1989 waitIfPossible (was wait).
1991 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1994 CCL operator names may be set in field definition files (CCL_bibset).
1995 See ccl/bib1 for an example.
1997 Fixes in ASN.1 compiler for C++ compatibility.
1999 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2000 and "op_or" to avoid conflict with C++.
2002 Fixed problem with GNU readline detection on Redhat 7.0.
2004 Added step-size for Scan backend handler.
2006 Fixed bug that made the frontend server crash when no attribute
2007 set was specified for scan.
2009 Front-end server automatically switches to original working directory
2010 when installed as an NT service. Previously -w had to be specified to
2013 Added extended attributes for retrieval module (data1), so that data1
2014 records carry d1_readXML/SGML attributes. d1_read also supports
2015 null-data rules ( <tag/>)
2017 On UNIX when POSIX threads are available, a separate library libyazthread
2018 is created. Programmers should link with that library and the yaz library
2019 when using threads. The reason for the split was that some applications
2020 on Linux, such as Apache, doesn't work well when using shared objects that
2023 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2024 (or any frontend server) in SSL mode by specifying ssl: followed by
2025 address. Only tested on UNIX.
2027 Added feature for CCL module. Virtual structure s=al or s=ol generates
2028 and-list and or-list respectively instead of phrase search.
2032 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2033 log_mask_str. This was done to avoid name conflicts with other libraries
2034 (such as other PHP extensions).
2036 Added raw OID member for preferred record syntax (request_format_raw)
2037 and returned record syntax (output_format_raw) for backend fetch method.
2039 Config file yaz-config now accepts options so that it returns specific
2040 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2042 Shared library support for UNIX using GNU libtool.
2044 * Modified backend interface. Request/Response struct's replaced by
2045 one read/write C struct. For example bend_fetchrequest and
2046 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2047 Every handler - even search has to be registered in bend_init
2048 handler. This means that the YAZ library no longer refers to
2049 external functions and it makes it possible to make the whole
2050 thing a single DLL/SO.
2052 Added Segment handler for backend server.
2054 Added Zmbol/Zebra administrative functions to YAZ client.
2056 Threaded frontend server on UNIX (when POSIX Threads are available).
2057 Starting the server with option -T enables multi-threading.
2061 Added configure option --enable-comp/disable-comp to control use
2062 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2063 located in sub directory asn.
2065 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2066 in ${exec_prefix}/bin along with the other programs yaz-client and
2069 GNU automake used to maintain makefiles.
2071 Added several OID's.
2073 Changed retrieval module so that we can load records with no abstract
2074 syntax defined. Tagpaths in these records are fully composed of string
2077 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2081 On UNIX, the generated makefile now supports a proper 'make install'.
2082 The prefix can be set via GNU configure to set the install location
2083 (default is /usr/local).
2085 * YAZ programs client and ztest were renamed to yaz-client and
2086 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2087 locations, such as /usr/bin,/usr/local/bin,etc.
2089 * YAZ Header files were moved from include to include/yaz. YAZ Header
2090 files are referred to as include <yaz/log.h> rather than <log.h>.
2091 The YAZ include path (-I ..) is therefore the same as before. Programmers
2092 should update their #include statements or use -Ipath/include/yaz
2093 instead. The main motivation for doing this change is that YAZ header files
2094 can be installed in "standard" locations /usr/include,/usr/local/include
2095 without introducing conflicts, since ALL YAZ header files are stored
2096 in subdirectory yaz (under /usr/include for example).
2098 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2099 rather than project/workspace files. We switched because project files
2100 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2103 Changed name of logging function, logf, to yaz_log, to prevent name
2104 clash with some math-log functions. The YAZ header log.h defines logf
2105 to yaz_log (#define) so there should be no incompatibilities by this
2108 Added bend_start/bend_stop handlers for server. These handler are
2109 called on start/stop of server. For windows they are called whenever
2110 a service is started/stopped.
2112 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2113 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2114 in util/yc.tcl. The auto-generated C code structures are, in a few
2115 cases, incompatible with the old decoders. There are differences in the
2116 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2117 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2118 The preprocessor variable ASN_COMPILED is defined when the compiled
2119 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2120 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2121 wish to use the old encoders/decoders you can specify --disable-yc
2124 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2125 version so that it supports both new - and old version of DB Update
2127 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2128 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2129 change. The name parameter can be set to 0 in which no name is specified
2130 for the construction. The macros odr_implicit and odr_explicit sets name
2131 parameter to zero for the construction involved. New macros
2132 odr_implicit_tag and odr_explicit_tag are similar to the others,
2133 except that a name parameter is added. For programmers' that don't use
2134 ODR they probably only need to change the call to z_APDU and z_External.
2136 Added access control facility by interfacing the TCP wrapper library.
2137 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2138 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2139 name of the daemon and enables the access control as specified in
2140 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2142 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2143 den Dool <H.M.vdnDool@kub.nl>.
2145 Added reference ID parameter to most functions in server API - refer
2146 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2148 Changed name of ccl library to libccl.a (was ccl.a).
2150 Fixed bug in decoder for Explain (Category TargetInfo).
2152 Added support for GNU readline in client. Thanks to Jacob Poulsen
2153 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2155 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2156 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2157 IMPLEMENTATION! This change was made to the development version before
2158 the ZIG decided to retract the amendment. If any users MUST be
2159 compatible with the original Update definition, PLEASE CONTACT US, and
2160 we will include a separate definition corresponding to the old Update
2161 ES. Note that because of the change to the ASN.1 of the
2162 TaskPackageRecordStructure we cannot define a single structure that
2163 will support both versions.
2165 * Added const modifier to buffer parameter for some ODR/BER encoding
2166 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2167 completeWAIS, odr_dumpBER.
2169 Fixed bug in client.c which caused a crash when a scanResponse didn't
2170 contain positionOfTerm.
2172 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2173 * will cause an error in a client if a non-YAZ target sends both a
2174 * list of Scan entries and non-surrogate diagnostics.
2176 Retrieval module enhancements. Tag sets may be typed in the reference
2177 to it. From the .abs-file the "tagset" directive takes a third optional
2178 integer type for the tag set referenced. From a .tag-file the "include"
2179 directive takes a third optional type as well. The old "type" directive
2180 in the tag set itself is still recognized but acts as the default type
2183 Backend interface change. Individual Scan terms returned from bend_scan
2184 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2185 in include/backend.h.
2187 Retrieval module enhancements. Multiple tag sets and attribute sets may
2188 be specified in abstract syntax specs. Revised the error/warning for
2189 logging messages reported by the retrieval module when reading the
2192 Object Identifier system (oid_..) changed. The API is backwards
2193 compatible but the oid-routines now allocates new OID's when needed.
2194 Raw OID's may be specified in oid_getvalbyname.
2196 YAZ now uses GNU configure to generate Makefile(s).
2198 * Minor changes in some of the member names of DeleteResultSetRequest and
2199 DeleteResultSetResponse. See include/proto.h.
2201 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2202 and added member 'languages' in TargetInfo (which was missing).
2204 Changed the way attribute sets are handled in the retrieval
2205 module. These are now cached, just like the abstract syntaxes
2208 Changed YAZ so that it links with compiled ASN.1.
2210 Added Explain-schema definitions and mapping routines. The following
2211 Explain categories have been implemented: AttributeDetails,
2212 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2214 Fixed minor bug in Windows version of Server Library.
2216 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2218 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2220 Added EXTERNAL: UNIverse Resource Report (non-standard).
2222 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2223 ENUMERATED and SET OF.
2225 * Added 'const' to some of the char pointer arguments for the
2226 functions, data1_read_node, data1_getelementbytagname,
2227 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2230 Fixed bug in data1_insert_taggeddata - the last_child member of
2231 parent wasn't initialised.
2233 * Changed data1_read_record and data1_read_node so that the supplied
2234 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2235 doesn't refer to any parts of the "SGML"-buffer.
2237 Fixed bug in server library (Windows version of statserv_remove).
2239 * Changed code so that it compiles as C++. The type definition
2240 of Odr_fun which is a member of Odr_arm was changed. The result is,
2241 that an explicit typecast is needed for the fun pointer when
2242 using Odr_arm - as in:
2243 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2245 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2247 Implemented the new structured date and time definition as approved
2248 by the ZIG. Added schemaId element to the specificTag in Espec-1
2249 (also approved at the last ZIG). Thanks to RVDM.
2251 Added some Object identifiers (RVDM).
2253 Changed the Update Extended Service (RVDM).
2255 Added command "refid" to client which specifies referenceId for
2256 the following requests.
2258 Implemented extended service handling for server. See ztest.c
2259 for an example as well as backend.h. New handlers are registerd
2260 in the Init handler.
2262 * Changed interface for sort in server.
2264 Added new members to statserv_options_block. It allows a server
2265 to read options from another source than just the command line. Thanks
2266 to Charles Woodfield.
2268 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2269 renamed to zboolean. Some C++ compilers complained about the name.
2271 Minor changes to gils.abs. Added index 's' (sort) on title
2272 and date/time-last-modified.
2274 --- 1.4pl2 1998/1/30
2276 Fixed bug in server library regarding inetd mode (-i). This bug
2277 was introduced by release 1.4.
2279 --- 1.4pl1 1998/1/29
2281 Added sort facility in client and backend server interface.
2283 Fixed problem with dependencies in Makefile(s).
2285 Fixed bugs for encoders/decoders of extended services and
2288 Implemented sub-tree feature for schemas. Sub-trees are
2289 referenced in *.abs-files. See explain.abs for an example
2290 of the use of this feature.
2292 Modified bib1.att; local attributes for ANY didn't include
2293 ANY itself (only affects use of the retrieval module).
2295 Fixed bug in plain SGML reader in function data1_read_node:
2296 tags with prefix "var" was incorrectly interpreted as variants.
2298 Added feature "sub-schemas" to enable references to - and definitions
2299 of - group of elements.
2301 * Removed member parent from type data1_element (in data1.h).
2303 Implemented function odr_nullval() that returns the value of
2306 * Removed member num_children from data1_node (in data1.h).
2308 Made NT service interface part of the server library. The
2309 function statserv_main uses the NT service when required and
2310 calls the statserv_start / statserv_close routines.
2312 Routine zget_SearchRequest and zget_PresentRequest fills
2313 resultSetName/Id member with "default" instead of "Default".
2315 Fixed memory leak in server. Request queue member wasn't freed.
2317 Fixed nmem_exit so that memory is freed.
2321 Revised the CCL parser utility to be thread safe.
2323 Added function, oid_ent_to_oid, to replace the function
2324 oid_getoidbyent, which is not thread safe.
2326 * Added nmem_init and nmem_exit to initialize and release
2327 NMEM resources. Function nmem_init should be called once in the
2328 initial thread before NMEM/ODR is used. statserv.c and client.c
2329 have been changed accordingly. The change was necessary to make
2330 NMEM thread safe. The NMEM memory pool is shared amongst threads
2331 in a process. Unix-based applications will still work fine without
2334 Added NT Services interface for the the Z39.50 (statserv) Server.
2335 Refer to the ztest.c source on the usage.
2337 Windows 95/NT port using MSVC5.0. Project files are included in the
2340 * Defined new 'global' handle for the retrieval (data1) system. The
2341 new handled, data1_handle, describes the state of the data1 system.
2342 This handle is passed as first argument to virtually all
2343 data1 related routines. The functions data1_create and data1_destroy
2344 creates and destroys a data1 handle respectively.
2346 Added ODR encode stream member to all backend request structures
2347 init, search, scan etc. This stream should be used to allocate all
2348 memory used for the response when thread safe operation is needed.
2350 Changed the comstack utility, cs_addstr, to be thread safe. The
2351 returned hostname string returned by the function is now part the
2354 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2355 function. The cs_straddr takes a COMSTACK handle as argument, so this
2356 function must be used after cs_create and before bind/connect.
2357 This function is thread safe.
2359 Moved test server to 'ztest' directory - generic server code still
2360 in 'server' directory.
2362 Made prefix query (pquery.c) utility thread safe.
2364 Added new function modifier YAZ_EXPORT to 'export' public DLL
2365 functions when using windows (see include/yconfig.h).
2367 Added definitions to the OID database (util/oid.c) (RVDM).
2369 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2371 Added call to ccl_rpn_delete in client program.
2373 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2374 release of RPN structure.
2376 Added support for C++, headers uses extern "C" for public definitions.
2377 With input from RVDM.
2379 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2380 Thanks to Ronald van der Meer (RVDM).
2382 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2384 Added support for private extensions to the OID database
2385 (oid_setprivateoids()). Thanks to RVDM.
2387 Added optional, physical ANY (key replication)
2389 Fixed null-reference problem in GRS-1 output filter.
2391 Proximity operator added to Prefix Query Format (PQF).
2393 In test client command "base" accepts multiple databases.
2395 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2399 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2401 Smallish bug-fixes in the new encoders/decoders (explain).
2403 Bug fixed in DeleteRequest.
2405 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2407 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2409 Added SOIF syntax (using private OID for now) to retrieval module and client.
2411 Added Update extended service.
2413 Added SearchResult-1 additional info structure.
2415 Added optional CCL (ISO8777) interpreter as separate module. Available
2418 --- 1.2 1996/6/10 (1st anniversary release)
2420 Added Summary record syntax. Lightly tested.
2422 Added OPAC record syntax. Untested.
2424 Added ResourceReport service encoders/decoders. Untested.
2426 Fixed bug in z_Unit - wrong tagging on unitSystem.
2428 Fixed bug in the DiagRecs decoder.
2430 Added options for max PDU size and session timeout to frontend-server.
2432 Added documentation of query-language parsers and other supporting utilities.
2434 [frontend-server] Added Attribute set to the bend_scanrequest API.
2436 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2437 surrogate diagnostics were generated.
2439 [retrieval] Allow multiple local values for attribute.
2441 [retrieval] Allow multiple attributes per element in .abs files. index type.
2443 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2445 --- 1.1pl2 1996/4/10
2447 Minor changes, mostly specific to Zebra's requirements (retrieval)
2451 Repaired bug in frontend server when running multiple listening
2452 endpoints in dynamic mode.
2454 z_External() now won't break if a known, ASN.1 value comes encapsulated
2455 in an octet-string. The value will pass through unmodified in an Odr_oct.
2457 Added a bit of code to the demo client to decode & display
2458 ASN.1-structured records represented in the octet-aligned branch of
2459 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2461 Added z_ext_getentbyref() to the ASN module. Doc updated.
2463 * Completed the SCAN definition in the ASN module. This may break SCAN
2464 code based on older YAZ-versions at compile-time. The fix is easy -
2467 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2468 under the SCAN definition. Remember to initialize this, server-people.
2470 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2471 that this does not extend to ODR and ASN.
2473 Comstack allows insertion of established socket (primarily for
2474 inetd-operation of servers). Doc updated.
2476 Front-end server can now start from the inetd in TCP mode. Doc
2479 --- 1.0pl4 1996/1/24
2483 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2484 the rank and record number.
2486 Adjustments to the frontend server.
2488 Fixed diagnostic BER dumper. It ignored the file argument.
2492 Various changes to retrieval module.
2494 Changed the union discriminators of the protocol files from enums to
2495 ints paired with #defines.
2497 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2500 *Changed operator in the RPN structure to 'roperator', again to avoid a
2503 Fixed problems in Explain decoders/encoders.
2505 --- 1.0pl2 1995/12/6
2507 Memory bug in log module fixed.
2509 --- 1.0pl1 1995/12/5
2511 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2513 Bug in Explain DatabaseInfo module fixed.
2515 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2519 The shift to v1.0 signals that we now consider the *core* functionality
2520 of YAZ reasonably stable (the core being more or less equivalent to
2521 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2522 tested (Explain not at all - though that will happen soonish).
2524 Minor changes to code to support Windows port.
2526 Various minor changes after we're getting to use GRS-1 & co. more.
2528 Added Espec-1 format.
2530 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2531 of the protocol and it cannot be selected when encoding (maps into 'string'
2532 when decoding). Needed to talk to some servers.
2534 Demo client can request simple element set names.
2536 Added Diagnostic Format encoders/decoders.
2538 Added simple Close handling to frontend server (no hooks for resource
2539 reporting yet), and demonstration client.
2541 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2543 --- 1.0b3 1995/08/24
2545 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2546 handled incorrectly when records were requested in the searchResponse. This
2547 will only affect you if you use the frontend-server.
2549 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2550 Test-client will ask for and print GRS1. Ztest will return dummy records
2553 Added Explain encoders/decoders to the service-level API. Untested.
2555 Added Extended Services: Item Order encoders and decoders to the Service-
2556 level API. Untested. We could use a recent copy of the pertinent bits
2557 of the ILL protocol to add those bits.
2559 Added diagnostic format 1 encoders/decoders to the service-level API.
2562 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2563 odr_cons.c, which causes a more correct output.
2565 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2566 was always set to 0 when no records were requested in the searchRequest.
2568 * Added better external-handling. This shouldn't harm old code that
2569 *encodes* externals. It can break code that looks for a
2570 'single-ASN1-type' representation, since those types that are known
2571 are now decoded immediately. Look at the SUTRS sample code in
2572 seshigh.c and client.c. Documentation updated.
2574 Handling of structured records in bend_fetchresponse. Length -1 marks
2575 structured record, type is deduced from format field.
2577 --- 1.0b2 1995/06/27
2578 Fairly quick maintenance release to add SUTRS support.
2580 Fixed handling of SUTRS records in the demonstration client.
2582 * Added format field to the bend_fetchrequest and bend_fetchresponce
2583 structures of the backend API (frontend server). When the record is
2584 returned, the value of the format field is mapped to an OID. The
2585 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2586 of the record. The special value VAL_NONE in the bend_request means
2587 that no specific format was requested by the client. Documentation
2588 updated accordingly. Test server (ztest) will return a fixed dummy
2589 SUTRS record if your client requests SUTRS.
2591 Documentation updated accordingly.
2593 You can now set external libraries and RANLIB support in the top-level
2597 First public release.
