3 Add support for extra request / response data for SRU codecs and GFS.
4 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
5 for extra data response buffer and length. For the GFS, both request
6 and response data (XML) is carried in extra_args and extra_response_data
7 for the search handler. Patch by Ko van der Sloot.
9 ZOOM: For queries that cannot be converted to the specified rpnCharset,
10 ZOOM now returns a diagnostic on the client-side ('invalid query' /
11 10010). This fixes bug #2113.
13 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
14 cmdfile included a 'quit' command that would result in a memory violation.
18 Make a number of functions defined in xmlquery.c static. These have
19 never been declared in a public header file (yaz/xmlquery.h) and was
20 made public by mistake.
22 Improve speed of character conversions (iconv utilities). This makes
23 conversions from MARC-8 faster.
25 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
26 unless type desired is "raw". This will prevent type "xml" from
27 returning ISO2709 .. Which obviously can not be XML parsed.
29 Fix memory leak in ZOOM that would occur if option apdulog was used
30 on a re-used connection.
32 Frontend server logs HTTP requests.
34 Frontend server now sends Z39.50 close when it times out (sesssion has
35 been idle for too long). Versions 2.0.30 and earlier also sent close.
36 But due to a mistake this was disabled in all versions after that, i.e.
37 the server would just close the socket immediately.
39 yaz-client emits a better message when receiving an unrecognised
42 Skip zero-length subfields when decoding ISO2709. This rare case happens
43 if a record has two FS characters in a sequence. Without this patch
44 there would be a reference beyond char array in using_code_len fragments
47 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
51 The show command offered by the zoomsh command now takes a 3d optional
52 parameter type which is what is passed to ZOOM_record. If the type
53 argument is omitted, "render" is used.
55 RPN to CQL conv may use USE string attributes (bug #2978).
57 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
61 Function yaz_xml2query allows a diagnostic element in the PQF XML
62 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
63 code and additional info respectively.
65 The BER BOOLEAN is now the integral type Odr_bool which still happens
66 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
67 typedef'd to Odr_int. This is still an integral 'int', but it may be
68 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
69 ASN-1 compiler as well as programs has been updated to use the new types.
73 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
74 only the bibliographic record was rendered. For type=opac, an OPAC
75 record is only returned if it is present.
77 iconv: small fix for encoding of advancegreek.
79 yaz-client: avoid double display of SRU/SRW records (bug #2798).
81 yaz-client: option auto_reconnect=on really reconnects.
83 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
85 server: avoid null ptr ref for for yaz_poll errors.
87 build: fix RPM build for RHEL 5.3.
89 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
93 Fixed bug #2709: TCP connect returns Invalid argument.
95 Fixed compilation for mingw.
97 Honor charset for raw records (ZOOM_record_get).
99 Fixed use of errno for threaded mode that was seen on Solaris 10.
101 Fixed argument passing with blanks in value for Windows Service.
103 Disable YAZ' own log rotate by default (no 1 GB limit).
104 The variable l_max_size which specifies the log file limit is set to 0
105 (DISABLED): This is due to the fact that YAZ is most often deployed using
106 logrotate. Also YAZ can not perform log rotate because of unsufficient
107 permissions (setuid).
109 --- 3.0.44 2009/02/17
111 List supported encodings in man page for yaz-iconv.
113 Fixed missing SSL libs for --libs output
115 Re-established OID record syntax application-xml. Nobody should use it
116 but we don't want to change soname because of this symbol being absent.
118 --- 3.0.42 2009/02/02
120 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
122 Added member named_result_sets for init handler struct for the GFS. This
123 allows a server to disable named result sets.
125 Removed OID record syntax application-xml.
127 Added support for rule-based transliterator for ICU wrapper of YAZ.
129 Fixed bug #1902: yaz-icu XML output.
131 Make YAZ checks Emacs friendly.
133 BITSTRING value shows value. Bug #2346.
135 ISO2709 decoding: skip control characters from indicator data.
137 Omit sort key by default in yaz-icu's output.
139 Allow combined single char options (again) for YAZ' options function.
141 Utility yaz-marcdump got option to display YAZ version (-V).
143 Allow YAZ to use ICU 3.4.
145 Added new ICU test case which illustrates removal of diacritics.
147 --- 3.0.41 2008/12/29
149 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
151 --- 3.0.40 2008/12/29
153 For configure, using option --without-xml2 also disables Libxslt/Libexslt
156 Fixed bug #2352: yaz-marcdump crashes for certain record.
158 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
160 Added support for Danmarc2 to UTF-8 conversion.
162 Added support for ISO5426 to UTF-8 conversion.
164 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
165 implementation version.
167 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
169 --- 3.0.38 2008/11/10
171 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
172 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
174 ZOOM C now interprets databaseName option for ZOOM connection as path
177 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
179 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
181 Dummy Libxml2 types no longer defined in headers of YAZ'.
183 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
186 --- 3.0.36 2008/09/26
188 Various ODR chapter fixes.
190 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
192 Added missing source for Windows compilation, mutex.c.
194 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
196 For SRU connections in ZOOM all records up to "count" are now fetched.
198 Fixed crash in generic frontend server (and yaz-ztest) which occurred
199 in Windows due to bad error handling for Libxml2.
201 Added facility for sending arbitrary records (ASN.1 any) using
202 ZOOM C's Extended service update. Patch by Sam Reynolds.
204 New options for ZOOM C's connection, logapdu which makes ZOOM log
207 --- 3.0.34 2008/06/18
209 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
211 --- 3.0.32 2008/06/12
213 Fixed memory violation that could occur when decoding UTF-8. This bug
214 was only present in 3.0.30 of YAZ.
216 --- 3.0.30 2008/06/06
218 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
219 GNU TLS is used by default (if found).
221 yaz-ztest returns OPAC records if a client asks for OPAC.
223 Improved speed of MARC-8 encoding.
225 Added support for lossy and loss-less MARC-8 encoding.
227 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
229 Added new Windows Service wrapper (sc).
231 yaz-client's itemorder command may now send a file.
233 Fixed yaz-marcdump to allow the use of NS prefix for record element.
235 Added new function yaz_log_xml_errors.
237 Allow (but warn) unknown XML attributes in MARCXML parsing.
239 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
241 The UTF-8 to MARC-8 conversion now uses a different set of characters
242 for Greek symbols. Bug #2120.
244 --- 3.0.26 2008/02/21
246 Added yaz_daemon (daemon.h).
248 Fixed bug #2068: pkg-config trouble
250 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
252 --- 3.0.24 2008/01/28
254 Document --with-xml2 option.
256 Added OPAC XML XSD (etc/opacxml.xsd).
258 Allow glob mask for name attribute in retrieval element for the
259 generic frontend server's retrieval facility.
261 Changed yaz_poll_poll to return yaz_poll_except for all returned events
262 except POLLIN/POLLOUT.
264 Fixed error handling in cs_listen. Bug #2037.
266 --- 3.0.22 2008/01/20
268 Fixed version in yaz/yaz-version.h.
270 Fixed bug #2027: Crash when closing connection.
272 Changed configure so that ICU support is only enabled if only ICU
273 and Libxml2 is available (because the ICU chain is XML based).
275 --- 3.0.20 2008/01/15
277 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
278 is built. Only this DLL depends on the ICU runtime.
280 yaz-ziffy is no longer part of YAZ. It is distributed separately by
281 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
283 Changed license of CCL module to 'Revised BSD'. After consultation with
284 remaining members of the original EUROPAGATE consortium, we are re-issuing
285 the CCL module without a separate license. The software was developed by
286 Index Data as part of a research project. The special license was included
287 to help feed usage information back to the project consortium to support
288 project evaluation. At this time, the project consortium has long-since
289 disbanded, and the majority of the original principals have retired. At the
290 same time, we have significantly modified the software during the following
291 years, to the point where very practically no original code remains. To
292 simplify re-use of the software, we have contacted those members of the
293 consortium who could be reached, and agreed to re-issue the module as a
294 proper part of the YAZ package.
296 Tcl scripts uses /usr/bin/tclsh as preferred shell.
298 CQL closer to being version 1.2 compliant. CQL also allows free-form
299 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
302 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
303 bug could make Extended services handling crash in the ZOOM layer. This
304 bug was only present in YAZ 3.0.18.
306 --- 3.0.18 2007/12/19
308 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
311 yaz-marcdump reads and writes collection wrapped records.
313 Handle OPAC for record conversion module.
315 Fixes for ICU wrapper.
317 Allow ICU libs to be controlled with --with-icu .
319 --- 3.0.16 2007/11/12
321 Added yaz_poll which is a wrapper for select/poll. When poll is available
322 and non-buggy, it is used, by yaz_poll . This allows more than 1024
323 sockets to be in use.
325 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
326 functionality through an XML based configuration (ICU chain). This system
327 is useful for search facilities such as Pazpar2 and Zebra that needs to
328 perform tokenization of indexed material. The ICU code in a separate
329 library libyaz3_icu.a.
331 Added HTTP tunnel facility for COMSTACK, bug #1752.
332 This is a facility that allows a Web proxy, such as squid, to tunnel
333 Z39.50 traffic. This facility is "transparent" to must applications
334 using YAZ. It's enabled by using pseudo transport connect: followed by
335 the proxy address, followed by command, then follwed by he regular
336 "virtual" addresss. For example,
337 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
339 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
341 --- 3.0.14 2007/09/21
343 Fixed bad memory reference in ZOOM_record - cuased by member not being
344 initialized. This was a problem only in YAZ 3.0.12.
346 Fixed bug in conversion from MARC to XML: Non-XML characters in control
347 fields were not removed.
349 Changed the way C code is generated from codetables.xml. Made a MARC-8
350 conversion trie for each characterSet section rather than codeTable.
351 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
352 of codetables.xml from Larry Dixson, LOC. Bug #1464.
354 --- 3.0.12 2007/09/12
356 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
357 from ZOOM_record_error).
359 ZOOM C function ZOOM_record_get returns record schema for type="schema".
361 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
363 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
365 Better SRW-to-Bib-1 diagnostic mapping.
367 ZOOM C and yaz-client announces SRU version 1.2 by default.
369 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
372 Fixed in yaz_sru_decode to allow other version than 1.1.
374 --- 3.0.10 2007/08/22
376 Added support for SRU scan for ZOOM.
378 Added support for the use of the older versions or Extended Service
379 Update in ZOOM. To faciliate this, an option "updateVersion" may be
380 set to the version , 1=first, 2=second, 3=third. The third version is
381 what ZOOM C has used so far. And that, obviously, is the default.
383 Added support for CCL queries in Z39.50 queries sent to the GFS (and
384 therefore in Zebra and in SimpleServer-based applications). The new
385 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
386 qualifier file used to transform incoming CCL queries into Type-1 RPN,
387 which is passed into the back-end search callback function.
389 Added support for HTTP Basic authentication in clients: the SRU/W
390 codec encodes the username/password elements of the PDU structure
391 appropriately, and these may be set using the "user" and "password"
392 options in ZOOM-C applications (the same options that are used for
393 Z39.50 authentication).
397 Fixed bug #1208: SSL appears to be broken in ZOOM.
399 Fixed bug #1206: Libxml2 include path weirdness.
401 Added oid_name_to_dotstring.
403 Allow elementSetName to be specified for ZOOM C record update.
405 Allow waitAction to be specified for ZOOM C based for Extended Services.
407 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
408 syntax OID. Bug introduced in YAZ 3 series.
410 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
414 Fixed bug #1157: yaz-client does not read .yazclientrc from current
415 directory. yaz-client now reads commands from file given by option -f
416 if specified; then tries to read .yazclientrc in current directory.
417 Failing that, it reads .yazclientrc from user's home directory.
419 Added support for correlationInfo Note and ID for Record Update via
422 Added yaz-client command querycharset which specifies character set for
423 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
424 (termListAndStartPoint).
426 Charset ISO5428:1984 is an alias for ISO5428-1984.
428 Implemented a way to perform scan in a result set using Z39.50. This
429 is achieved by attaching the result set name in the characterInfo
430 (type InternationalString) of OtherInformation in the Scan Request PDU.
431 The result set is identified in the otherinformation by the new OID:
432 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
433 This allows for scan in result set and faceted search . Zebra did some
434 of this in the APT term using attribute type 8 and value being result
435 set. Using the OtherInformation approach for this is cleaner and easier
436 to work with in proxies and the like. This facility can be used in
437 yaz-client using new command setscan which takes a result set as first
438 argument, start position (APT) as second.
440 Changed decoding of SRU XML packed records to deal with servers that
441 have recordData with XML data with multiple root nodes. Also make
442 comparison for recordPacking case insensitive. Again, one server
443 returns "XML" where others return "xml".
445 For SRU responses allow Content-Type application/xml as well as text/xml.
449 Fixed bug in character set conversion of BER strings. Bug introduced
454 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
456 For OID class, use oid_class consistently.
458 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
461 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
462 character set for bibliographic information interchange". By Giannis Kosmas.
464 Added documentation on new OID API.
468 Changes to generic frontend server interface: added new member
469 'query_charset' for bend_initrequest structure. A backend init handler
470 should set this member to its native character set for query terms.
471 When defined, the frontend server logic will announce this character set
472 to a client if the negotiationModel bit is set by the client. All server
473 implementors are encouraged to specify this. If a backend server does not
474 specify this a warning is issued using yaz_log(YLOG_WARN,..).
476 Added CCL utility to remove terms (stop words) from resulting RPN
477 tree. This is handled by functions with prefix ccl_stop_words_ .
479 New ZOOM C option, "rpnCharset", which allows client-side conversion of
480 terms in RPN queries.
482 Clean-up the CCL API. Moved some internal structures from ccl.h to
483 private header cclp.h. Changed ccl_parser_create so that a Bibset must
484 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
485 This is replaced by ccl_parser_find_str which takes a string instead.
487 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
488 libyaz.la is the core of YAZ except the generic frontend server and
489 does not depend on POSIX threads anymore. libyaz_server.la is the
490 generic frontend server facilities and uses POSIX thread functionality
491 if available. The libyaz.la no longer depends on POSIX threads because
492 the number of global structures is limited. NMEM no longer re-uses blocks
493 between threads ; it simply free's memory immediately but allocates in
494 "large" chunks as usual. We don't expect any performance penalties
495 because of this. The yaz_log system is still using a global log_level so
496 caution must be taken when modifying it with yaz_log_init_.. +
497 yaz_log_mask_str. This, however, should not cause any trouble because
498 these functions are called during initialization of application code
499 anyway. `yaz-config --libs server` returns libs for server applications;
500 `yaz-config --libs` returns libs for non-server applications.
502 New OID database - with public definitions in oid_db.h. Removed old OID
503 database including the head oid.h and definitions such as enum oid_value
504 and struct oident. The new OID database uses the same string names as
505 before but the 'protocol' is gone. There are now only two representations
506 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
507 converts from string to OID; functions with prefix yaz_oid_to_string
508 converts the other way.
510 Change to emit_term() in CQL-to-PQF query translation: when a term has
511 the /regexp relation modifier, do not process it for leading and
512 trailing "^" and "*", which have quite different meanings in regular
515 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
516 write handlers no longer carries a 'last' parameter. This will make
517 yaz_iconv flush "less" characters. A flush is performed by call to
518 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
520 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
521 removed, because function yaz_query_to_wrbuf does the same.
523 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
524 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
526 Deprecated MARC utility functions removed.
528 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
531 Branch split: YAZ_2_1_55_branch
533 --- 2.1.54 2007/03/16
535 Fix to ZOOM-C so that transparent reconnection is properly handled on
536 connections that are in asynchronous mode.
538 Fixed compilation on OpenBSD 4.0.
540 Large strings in GRS-1 records are now properly displayed in yaz-client.
542 Added character conversion support for "advancegreek"; based on patch from
545 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
546 sequence is met. Before the error was not set so it would be unknown.
548 Adjust yaz-marcdump MARC reader so that it skips until record separator
551 --- 2.1.52 2007/03/07
553 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
554 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
555 fd_set structure used as a bitmask for the FDs to be selected on.
557 Using ACX_PTHREAD macro to check for POSIX threads.
559 Fixed have-vsnprintf check.
561 --- 2.1.50 2007/02/23
563 Fixes for configure on BSD. Bug #900.
565 Added snprintf/vsnprintf wrappers for systems that don't have
566 limits (heavens forbid).
568 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
569 created before all previous tasks were completed and removed from the
570 task queue, the new task could be removed by a mistake.
572 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
574 Implemented pass-through CQL-to-PQF conversions. Bug #861.
576 Fixed bug #832: Problem with MARC/charset in yaz-client.
578 Fixed bug #668: save command line history for yaz-client.
580 Fixed bug #830: pkg-config support.
582 --- 2.1.48 2007/01/23
584 Extended ZOOM result set options with two options that may be read by
585 a client: resultSetStatus and presentStatus with values as specified for
587 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
589 Fixed bug #827: Using SSL fails on Debian etch.
591 Fixed bug #826: Weird looking chars for set of MARC records.
593 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
594 that is treated as an ItemOrder with itemRequest being an XML document
595 external. The value of "doc" is the content.
597 Extended the GFS search facility. New member of bend_search_rr
598 'estimated_hit_count' signals that hits is known to be an estmate
599 (higher or lower than real hit count). New member 'partial_resultset'
600 signals that the search was partial (hit count is lower or equal than
601 real hit count). For Z39.50, the information is stored in resultSetStatus
602 member of SearchResponse APDU. For SRU, the information is signalled
603 via SRU diagnostic 59: "Result set created with valid partial results
606 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
608 --- 2.1.46 2007/01/13
610 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
612 Added ZOOM_connection_peek_event.
614 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
615 the following new functions:
616 ZOOM_event_nonblock, ZOOM_connection_process,
617 ZOOM_connection_get_{socket,mask,timeout},
618 ZOOM_connection_fire_event_{timeout,socket}.
619 The existing blocking event handler, ZOOM_event, is a wrapper for the
620 + blocking ZOOM_event_sys_{poll,select}.
622 Implemented function ccl_xml_config which parses XML version of CCL
623 configuration (bug #798).
625 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
627 Added timings utility (yaz/timing.h)
629 --- 2.1.44 2007/01/03
631 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
634 Fixed bug #779: Rotation of apdu.log fails.
636 Fixed for character set conversions:
637 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
638 Honor G1 set in MARC-8 decoding.
640 --- 2.1.42 2006/12/17
642 Fixed bug #775: char conversion does not handle Alternative UTF-8
645 Implemented function yaz_marc_read_line which parses MARC line format
646 records. There is a wealth of formats out there. So far, this function
647 reads line records produced by yaz_marc_write_line.
649 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
650 more generic and easier to remember(!) options: -i format and -o format
651 which specifies input format and output format respectively - where
652 format is one of "marc", "marcxml", "line", "marcxchange".
654 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
655 does not print anything except warnings for records.
657 For yaz-marcdump, added support for MARC split into files (-s) with a given
660 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
661 spec, at http://www.loc.gov/standards/sru/record-update/
662 This has changed the binary layout of the following structs:
663 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
664 bend_update_rr . Patch by Ko van der Sloot.
666 Added GFS utility function bend_assoc_is_alive which returns 1 if
667 association is still alive (client is connected); 0 otherwise (client
668 closed connection). This allows busy servers to stop working for
671 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
672 been a separate piece of software. This version of ziffy has been modified
673 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
675 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
677 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
678 Client code may now interrogate options such as "init_opt_sort" to
679 find out whether the server claims to support various options.
681 --- 2.1.40 2006/11/27
683 Added utilities yaz_{set,get}_esn to set/get element set name from
686 Removed the build of libyazthread.la. The libyaz.so is the threaded version
687 of YAZ and has been so since YAZ 2.1.10.
689 Implemented ZOOM_record_error which returns error information for
690 record (surrogate diagnostic).
692 --- 2.1.38 2006/10/31
694 Updates for SRU Update by Ko van der Sloot:
695 1. Changed name from "operation" to "action"
696 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
697 versions in the code, marked as 'backward compatible'.
698 3. Added diagnostics for SRU Update.
700 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
702 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
704 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
706 For GFS, fixed problem with SRU diagnostic 'First record position out of
707 range' being issued for 0 hits.
709 zoomtst10 part of Windows Build.
711 --- 2.1.36 2006/10/13
713 Implemented yaz_filepath_comp which splits a path into file path
714 components (required by Zebra 2.0.3+).
716 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
717 BSD inspired license until now so this should not have any real impact on
718 anybody. See http://www.opensource.org/licenses/bsd-license.php
720 Fixed bug #687: Missing log lines.
722 Fixed bug #678: CQL to PQF translation does not preserve double-quote
725 Fixed bug #689: SRU diagnostics to be added.
727 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
728 whether a connection is idle (no more work do do).
730 --- 2.1.34 2006/10/04
732 Change type of optval from long to int for invocation of setsockopt with
733 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
735 Added support for specifying the max log file size for the Generic
736 Frontend Server. The size is given with option -r.
738 --- 2.1.32 2006/09/21
740 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
742 --- 2.1.30 2006/09/17
744 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
747 Fixed bug in Generic Frontend Server that could cause a server to stop
748 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
750 For the generic frontend server, the maximum record size is used as maximum
751 size of incoming packages (SRU + Z39.50). The value until was previously
752 only used in Z39.50 Init negotiation and, later, in a session controlled
753 sizes of records returned. This is controlled using -k option. It can be
754 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
756 --- 2.1.28 2006/09/04
758 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
761 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
763 New option for yaz-marcdump -lpos=value which allows setting a portion
764 of MARC header to a certain value.
766 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
768 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
769 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
771 --- 2.1.26 2006/08/15
773 Fixed problem with SRU mode type (soap, get, post) for yaz-client
776 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
778 --- 2.1.24 2006/08/08
780 Fixed MARC ISO2709 encoding routines to deal with character set
783 Minor changes to GFS logging. Database included in search request log
786 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
787 cached/multiple records.
789 Shared libraries are built by default on Unix+configure.
791 Changed cql2pqf transformation to use a different evaluation order. The
792 new order is: always, relation, structure, position, truncation, index
793 and relationModifier. Old order was: always, relation, relationModifier,
794 structure, index, position, truncation. Note that the the latter ones
795 override former ones for identical attributes.. The new scheme means that
796 it is possible to override any existing attribute with a relationModifier.
797 And also that it is possible to override everything for the index rule
798 (except the ones listed in relationModifier). No order is perfect but this
799 one, we believe, covers more real cases.. The "always" should have been
800 called "default", since the attributes there can be overridden with all
803 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
804 compilation phase, but also for yaz-config --cflags output. This allows
805 us to have public headers with Libxml2 stuff in them . It should also,
806 eventually, make Libxml2 checks redundant in packages using YAZ, such
809 --- 2.1.22 2006/06/15
811 Changed SRU update structure bend_update_rr so that SRU diagnostics are
812 stored in uri, message and details.. Previously diagnostics were stored
813 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
814 compatibility.. but he's probably the only one affected, so.
816 Added support for CCL, compiled on the client side, in ZOOM-C. This
817 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
818 input; the resulting query objects can be used for for searching with
819 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
821 YAZ' configure searches for OpenSSL by default.
823 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
824 SL_CTX_use_certificate_file. See
825 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
826 for more info. Thanks to Ko van der Sloot.
828 --- 2.1.20 2006/06/02
830 Bug #600: SRU GET, POST support for yaz-client. Introduced
831 command 'sru' which selects method SOAP/GET/POST.
833 Allow missingValueAction to be specified for the sortspec string -
834 function yaz_sort_spec. By default, the missing value action is null.
835 Use ! to specify "abort". Use = followed by stringvalue to specify default
838 Ensured that Present-handler (if defined) is called in GFS before any call to
839 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
840 searchRetrieve requests.
842 Documentation for YAZ is now based on the Docbook XML/XSLT using
843 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
844 is no longer depending on jade/openjade or docbook-to-man scripts.
845 PDF is no longer part of the distribution - but can optionally be
846 made using DSSSL/jadetex or FOP.
848 Added retrieval handling support in Generic Frontend Server to support
849 conversion between MARC/XML as well as XSLTtransforms. See
850 etc/yazgfs.xml for an example.
852 Added Authentication support to Generic Frontend Server in SRU
853 mode. Authentication using HTTP Basic is supported, as is the use
854 of 'x-username' and 'x-password' parameters in the request itself.
856 Added support for a new character set MARC8s identical to MARC8 except
857 that it converts combined characters to single Unicode characters in the
858 Latin-1 range (when possible).
860 --- 2.1.18 2006/04/24
862 ASN.1 compiler 0.4: generates brief Doxygen file header for
863 generated .h/.c files.
865 Utility yaz_iconv now supports conversion to MARC-8.
867 New facilities for the MARC module. The reading - and writing of
868 content are separate methods for the yaz_marc_t handle. The following
869 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
870 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
871 format). Write functions have prefix yaz_marc_write_.. The existing
872 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
873 available. Removed support for OAI-MARC and simplexml (not the
874 simplexml from PHP5).
876 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
877 to be returned for this connection.
879 --- 2.1.16 2006/03/31
881 Allow multiple languages and charsets to be specified with
882 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
883 negcharset iso-8859-1,utf-8
885 Translation of proximity nodes from CQL into PQF now works.
887 Moved to automake 1.8, 1.9.
889 Added function yaz_log_set_handler which allows a log handler to be
890 installed. This handler will be called for all log messages. Output
891 to file is also produced; but that can be disabled by passing NULL
892 fname to yaz_log_init_file.
894 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
896 For SRW (including GFS), accept application/soap+xml as content-type
899 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
900 produces NO stylesheet reference even if a default stylesheet is specified
903 --- 2.1.14 2006/03/14
905 Updated Windows package to include yazd.dll + yazd.lib for the
906 Development component.
908 If the environment variable YAZ_LOG is set, then it is used as a
909 string indicating the default level of logging to use if not
910 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
911 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
912 used as before. So, for example, to omit warnings from YAZ logging,
915 cql_transform() now map structure and other attributes before indexes,
916 so that index-specific structures and other attributes can override
917 defaults. So now a combination of mapping specifications such as:
919 index.dc.date = 1=date-modified 4=5
920 does the right thing.
922 cql_transform() now also respects the "always" mapping specification,
923 which establishes an initial set of attributes to be used for all
924 terms except where overridden by more specific attributes associated
925 with the index, relation or modifier.
927 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
928 which mode to use; one of "post", "get" or "soap" (SRW, default).
930 Fixes for yaz_iconv routines: changed trie-based character set conversions
931 to use only non-negative values for bit fields due to Sun's C compiler not
932 supporting negative values.
934 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
935 sequences where not read correctly. Fix by Rustam Usmanov.
937 Updated win/makefile to use options, settings which makes things
938 compile with VS C 2005.
940 --- 2.1.12 2006/02/01
942 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
944 In ZOOM socket code, use select instead of poll on MacOSX.
946 ZOOM-C now support client-side compilation of CQL into RPN that is
947 sent to the server, enabling CQL to be used against all Z39.50
948 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
949 ZOOM_query object, and submit it using ZOOM_connection_search().
950 The CQL-to-RPN translation uses a configuration file, the name of
951 which must be specified in the Connection's "cqlfile" option.
953 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
954 function, which takes as its start-term parameter a ZOOM_query object
955 (which may have had either CQL or RPN set into it).
958 --- 2.1.10 2005/11/29
960 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
961 GFS to support this as well. Backend handler, bend_srw_update, does the
962 update work. Code contributed by Ko van der Sloot.
964 Allow retrieval of Search Result-1 information in ZOOM by the use of
965 options that are attached to a result set. ZOOM documentation updated
968 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
969 UTF-8 conversion. Patch by Raj Patel.
971 Added option -m to GFS to control formatting of timestamps in log file.
973 Added 'exit' as synonym for 'quit' in yaz-client
975 Added support for specifying SRW resultSetId + resultSetIdleTime in a
976 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
977 for the new members. Patch by Ko van der Sloot.
979 Added support for SRU POST. It is supported for content-type
980 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
982 Do not build the separate Multi-threaded (MT) library libyazthread.la.
983 Instead make the library libyaz.la multi-threaded. Threading as a whole
984 can still be disabled by configure option --disable-threads. Previosly,
985 with older GLIBCs there were problems with MT libs under Apache. This
986 has now been fixed a long time ago.
988 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
991 CQL module modified to be case insensitive for relations/indexes/operations.
993 Fixed bug in CQL transform code: incorrect value relationModifieder
996 Added 'show all' command for yaz-client which retrieves all results
999 Added new yaz-client, xmles, which takes a (private) OID and
1000 a document to be sent as an extended service request.
1002 Describe new yaz-client commands wait_response and set_auto_wait.
1004 Increase TCP/IP listener backlog from 3 (which I am guessing was
1005 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1006 that the socket will queue as many incoming connections as it's able
1007 to handle ongoing connections. In other words, it will never now
1008 refuse a connection that it would be able to handle merely because
1009 it's not got around to accepting() enough of the pending connections
1010 yet. This is the behaviour anyway under Linux, where the listen()
1011 argument is ignored; but not under BSD and on systems such as
1012 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1013 YAZ-based servers should now be uniform across operating systems in
1016 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1017 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1018 This allows yaz-marcdump to read large MARC batches (>2 GB).
1020 Modified all YAZ source files - except the source which is auto-generated
1021 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1024 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1025 corresponding to the existing *_setl() function. These allow option
1026 values containing arbitrary valuues.
1028 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1029 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1030 except that it returns an indicator of whether or not the sort
1031 criterion was accepted (0 for OK, -1 for invalid).
1033 --- 2.1.8 2005/06/07
1035 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1036 MARC output rather than returning "new" buffer.
1038 yaz-client warns about unknown init options.
1040 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1042 --- 2.1.6 2005/05/24
1044 Added support for SRW sort in Generic Frontend Server. Patch
1045 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1046 sortKeys - or NULL if none is provided.
1048 Fixed bug #307: It was impossible to specify indefinite/no timeout
1049 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1052 Added support for multiple languages and charsets to be specified in
1053 ZOOM. Each charset/language is separated by a blank. If negotiation is
1054 in effect in init-response, Option
1055 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1056 Code based on patch by Vasiliy Osadchuk.
1058 Fixed bug #306: infinite recursion that occurred when calling
1059 yaz_log_level_init as the first call (before other log level or
1062 Fixed bug in scan handling in front end server: if preferred-Position-In-
1063 Response was non-present, a NULL pointer referece was performed.
1065 --- 2.1.4 2005/04/26
1067 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1068 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1069 now defined for all those error codes. So instead of putting 109 in
1070 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1071 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1073 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1076 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1078 Program yaz-client now exits and produces an error message if multiple
1079 Z39.50 servers are specified on the command line (none or one allowed
1082 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1085 --- 2.1.2 2005/03/16
1087 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1089 Fixed bug #272: Preserve spacing for CCL terms.
1091 --- 2.1.0 2005/03/14
1093 Added support for virtual hosts and multiple backend servers for
1094 the YAZ frontend server. The configution is XML based and
1095 support specificition of CQL to RPN mappings and explain information.
1096 See section "Virtual Hosts" in the YAZ manual.
1098 Extended OPAC display utility. OPAC display utility renders
1099 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1100 to supplement yaz_marc_decode_wrbuf.
1102 Fixed a bug in MARC decoder that could caused it to crash for some
1103 invalid MARC records. More diagnostics and warnings where added in
1104 XML output (warnings, etc are stored in comments).
1106 --- 2.0.34 2005/02/08
1108 Fixes for UNIX domain sockets. Bug #261.
1110 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1112 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1113 Added yaz_marc_subfield_str which defines subfield lead string which is
1114 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1115 yaz_marc_endline_str which defines end of fields string used in
1116 YAZ_MARC_LINE format. Default string is newline.
1118 Experimental support for MarcXChange. This format can be produced
1119 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1120 http://www.bs.dk/standards/MarcXchange.xsd
1122 Added yaz-client commands scansize that sets maximum number of
1123 entries to be returned by scan.
1125 --- 2.0.32 2005/01/11
1127 Added support for SRW scan in yaz-client and Generic Frontend Server.
1129 * Added whereInList member to SRW Scan Term.
1131 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1133 Fixed NMEM system to return aligned blocks on the smallest boundaries
1134 that are suitably aligned for all possible types on the particular
1135 architecture YAZ is being built for.
1137 --- 2.0.30 2005/01/04
1139 Fixed numerious warnings that was issued with newer versions of GCC.
1141 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1142 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1145 Make YAZ Generic Frontend Server slightly faster.
1147 Enhance (and reduce) logging for Generic Frontend Server.
1149 Revert YAZ log system so that it flushes every write operation
1150 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1152 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1153 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1154 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1155 will effectively disable old definitions.
1157 --- 2.0.28 2004/11/09
1159 Added yaz_log_time_format which specifies log format using
1162 Added yaz_log_module_level which returns mask for a module. Value
1163 is non-zero mask a if module is enabled; zero if disabled.
1165 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1166 in include/yaz/cql.h.
1168 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1170 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1172 Fixed bug #172: RPM builds does not enable SSL.
1174 Doxyfile.in part of dist. Doxyfile generated by configure.
1176 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1177 are given and the corresponding component does not exist.
1179 Extend CCL documentation in YAZ reference. Describe r=r.
1181 --- 2.0.26 2004/10/01
1183 Fixed MARC->MARCXML conversion to properly deal with
1184 fields, subfields, indicators having non-ASCII characters.
1186 Fixed MARC->MARCXML conversion so that ASCII control characters
1187 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1190 Added YAZ GFS support for conversion from Z39.50 surrogate
1191 diagnostics to SRW surrogate diagnostics.
1193 Bug fix: YAZ GFS did not return schema in explainResponse.
1195 --- 2.0.25 2004/09/30
1197 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1198 now converts recordSchema to elementSetName as well as schema URI.
1200 Fixed bug in COMSTACK that prevented HTTP request packages from being
1203 --- 2.0.24 2004/09/29
1205 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1206 does not require white-space before and after the dash in a range, e.g.
1207 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1210 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1211 due to new GCC removing "redundant" code.
1213 Added yaz-client commands scanpos and scanstep that sets preferred
1214 position and step-size for scan.
1216 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1218 Added CCL utility ccl_qual_buf which parses one or more CCL
1219 spec lines in a buffer.
1221 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1222 of name and value - ignoring empty lines and comments.
1224 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1226 Added odr_get_element_path which returns current element path for an
1227 ODR handle. This utility is useful in error handling or user-defined
1230 Added ODR_PRINT utility odr_set_stream which is is a more generic
1231 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1232 to a write function and pointer to close function. The close function - if
1233 non-NULL - will be called during odr_destroy.
1235 Fixed bug in CCL parser where truncation char was not removed from
1236 right side when truncation=both was in effect.
1238 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1241 --- 2.0.23 2004/08/11
1243 Fix buffer overrun in CQL parser when dealing with proximity (%).
1245 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1246 to UTF-8/UCS conversion is now only based on codetables.xml.
1248 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1250 --- 2.0.22 2004/08/06
1252 Add support for more "commit changes" in ZOOM (uses Extended Services).
1254 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1257 Yet another small fix for configure of SSL.
1259 --- 2.0.21 2004/05/14
1261 Fix SSL libs for configure when --with-openssl=DIR is given.
1263 --- 2.0.20 2004/05/10
1265 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1267 SSL comstack now uses yaz.pem certificate file on server side
1268 by default. Certificate filename can be configured by calling
1269 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1271 Fix bug regarding multiple calls to ZOOM_connection_connect.
1273 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1275 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1276 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1278 ZOOM now allows inspection of X509 peer certificate for verification.
1279 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1281 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1282 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1283 as "modular" but it simplifies things.
1285 Added cs_get_peer_certificate to that returns peer X509 PEM.
1287 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1288 NULL if SSL is unavailable.
1290 Documentation about MARC decoding tools.
1292 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1294 --- 2.0.19 2004/03/30
1296 Rename CHANGELOG to NEWS to follow GNU style packing.
1298 Fix bug with missing initialization of member in init_diagnostics.
1299 This bug affects threaded version of GFS server.
1301 --- 2.0.18 2004/03/20
1303 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1306 Ensure zlib.dll is packed with Windows install.
1308 --- 2.0.17 2004/03/17
1310 Fix encoding of xsd:string to use text instead of CDATA.
1312 Fix endless loop in CQL parser with unbalanced ".
1314 Use a more compact way to store MARC-8 conversion tables.
1316 --- 2.0.16 2004/03/16 Debian only
1318 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1321 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1326 --- 2.0.15 2004/03/01
1328 Another fix for decoding of XML packed records.
1330 --- 2.0.14 2004/02/25
1332 Fixes for Chunked encoding. White space not ignored after length spec.
1334 Update NS and use default NS for SRW diagnostic elements.
1336 --- 2.0.13 2004/02/23
1338 Implement ZOOM_resultset_cache_reset which resets record cache.
1340 Implement ZOOM_resultset_sort which sorts a result set.
1342 Implement chunked HTTP transfer.
1344 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1346 --- 2.0.12 2004/02/16
1348 Added member 'schema' to bend_explain_rr structure so that backend
1349 can specify explain record identifier. Defaults to Zeerex 2.0.
1351 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1353 --- 2.0.11 2004/02/16
1355 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1358 Added init command for yaz-client which sends "extra" init request.
1360 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1361 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1363 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1365 Make ZOOM error code for "invalid query".
1367 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1369 --- 2.0.10 2004/02/05
1371 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1374 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1376 Added option -p <file> to make Generic Frontend Server to write PID file.
1378 Added option -D to put Generic Frontend Server in background on its own.
1380 Make ZOOM C recognize option "password". If unset, "pass" is used
1381 (for backwards compatibility).
1383 Fixed a bug in Generic Frontend Server that could make it crash if a
1384 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1387 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1388 Must be issued before open, in order to be in effect.
1390 --- 2.0.9-6 2004/01/12 Debian/Windows
1392 Make the SRU server more picky WRT unknown params, etc.
1394 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1396 New YAZ client command, options, that sets Z39.50 options.
1398 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1399 options from a string of tokens (one token for each option bit).
1401 Update SRW diagnostic code messages.
1403 --- 2.0.9-5 2004/01/07 Debian/Windows
1405 Handle user defined stylesheet for SRW/SRU.
1407 --- 2.0.9-4 2004/01/06 Debian/Windows
1409 Fix bug in decoding of Content-Length.
1411 --- 2.0.9-3 2004/01/06 Debian/Windows
1413 Fix a bug with decoding of XML packed records.
1415 --- 2.0.9-2 2004/01/05 Debian only
1417 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1419 Fix bug in SRW/SRU diagnostics decoding.
1421 --- 2.0.9 2004/01/05
1423 Fixed bug in Generic Frontend Server which could drop records exceeding
1424 preferred message size. Reported and fixed by Irina Dijour.
1426 Fixed calculation of package size for structured records in Generic
1427 Frontend Server. Reported and fixed by Irina Dijour.
1429 Fixed namespace for SRW/SRU diagnostics.
1431 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1433 --- 2.0.8 2003/12/22
1435 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1436 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1439 CQL changes to reflect recent changes to the specification:
1440 * Documentation talks about context sets instead of index sets.
1441 * Documentation talks about indexes instead of qualifiers.
1442 * The CQL-to-PQF transformer's configuration file now uses
1443 "index.set.name = <attributes>" instead of the old form
1444 "qualifier.set.name = <attributes>". (Both forms are still
1445 understood but the latter is deprecated.)
1446 * CQL terms with no explicit index specified are now interpreted as
1447 cql.serverChoice instead of srw.serverChoice (which of course
1448 behaves exactly the same.)
1450 --- 2.0.7 2003/12/16
1452 MARC conversion can now generate ISO2709 output in another
1453 character set. yaz-marcdump uses this facility if you invoke it
1456 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1457 functions from there can be used from C++.
1459 --- 2.0.6 2003/12/04
1461 Frontend server now transfers memory from decoded packages to stream
1464 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1465 references to show up.
1467 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1468 the ZOOM Abstract API. The older names for the same options are still
1469 also supported for the benefit of old applications.
1471 ZOOM-C supports "implementationId" and "implementationVersion" options
1472 to go along with "implementationName". These allow the user code to
1473 specify identification strings to be sent to servers.
1474 Add OID for the new ExtLite attribute set.
1476 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1477 as requested/supplid by Ere Maijala <ere@atp.fi>
1479 For generic frontend server, reverse the order of
1480 "toolkit-supplied / application-supplied" strings sent as implementationId,
1481 Name and Version. Also, remove the spaces around the slash. This brings
1482 the GFS in line with the behaviour of ZOOM-C on the client side.
1484 Add function ZOOM_scanset_display_term.
1486 yaz-client shows scan displayTerm if present.
1488 Utility yaz-iconv is now installed by default along with the man page
1491 Extend configure check for OpenSSL to use pkg-config where available (such
1494 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1495 server to specify uid/gid/mask for socket using the format
1496 unix:[user=uid,][group=gid,][umask=mask,]file=path
1497 If file= is omitted the existing format is assumed, e.g.
1499 in which case the mask is 0666 (rw for everybody).
1501 Major restructure of YAZ source. All source in libyaz is in src directory.
1502 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1503 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1505 Added man page for utility yaz-marcdump (used to be called marcdump).
1506 yaz-marcdump is installed by 'make install'.
1508 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1509 of incoming package failed.
1511 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1513 Change prototype of odr_perror: add const to message string.
1515 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1517 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1518 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1519 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1520 DNS lookup. There should not be any compatibility problems with this
1521 assuming that blocking=1 or 0 is used.
1523 Fix bad reference in UNIX comstack in function cs_addrstr.
1525 Fix for compilation on AIX.
1527 The generic front-end server (server/seshigh.c) now supports returning
1528 Init diagnostics to the client in User-information-field, in
1529 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1532 --- 2.0.4 2003/09/04
1534 Allow any CQL relation (not just all,any,exact,scr).
1536 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1537 that features the same UI.
1539 Implemented command update0 in YAZ client which is equivalent to
1540 update but uses old of Ext Update ASN.1.
1542 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1543 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1544 Previously no OID was used for this info.
1546 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1547 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1548 returns 'malformed search term' otherwise.
1550 SortResponse member resultCount now set to NULL in sort handler of
1553 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1556 Add three new utility functions for translating OIDs between various
1557 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1558 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1559 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1560 char *oid_to_dotstring(const int *oid, char *oidbuf);
1561 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1563 Reverted modifications for ES Update definition for z_IU0Update
1564 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1565 is back to YAZ 2.0.2.
1567 String value attributes for CCL parser.
1569 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1570 which their FirstSearch server returns in Init responses, sometimes
1571 carrying useful diagnostic information when Init fails. This has the
1572 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1573 "z39.50/oclcui.asn", where its definition is somewhat different from
1574 what OCLC document on their web-site, as required to interoperate with
1577 Support for anonymous authentication in yaz-client. Use the command
1580 * Fix the OID of the Index Data-local "admin" Extended Service from
1581 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1582 the 1000, which indicates a locally-defined OID, was a mistake.
1584 --- 2.0.3 2003/06/20
1586 Fix CCL directive @case handling so that it affects string match for
1587 both CCL keywords and qualifiers.
1589 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1590 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1591 Decoder has been updated with ASN.1 changes as listed in
1592 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1593 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1594 z_IUUpdate, remains unchanged.
1596 ZOOM_record_get may now return a record in a specific character set.
1597 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1598 "from" is the character set of record as returned by target. "to" is
1599 the character set to be returned. If omitted, "to" is UTF-8.
1601 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1603 New ODR utility, odr_getelement, which returns name of element for
1604 which encoding/decoding failed.
1606 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1607 in cases where a required element was omitted.
1609 Bug fix: some MARC8 sequences were not converted.
1611 New ZOOM option "step" which specifies number of records to be
1612 retrieved in one chunk. Used in conjunction with "start" and "count".
1614 SRW support for yaz-client. Use scheme http: to use it, e.g.
1617 yaz-client no longer does (un)intelligent character set conversions
1618 by default. Can be enabled with charset and marc_charset commands.
1620 xmalloc trace fix for 64-bit systems such as DEC alpha.
1622 Solaris 2.6 compile fix.
1624 New function, cql_strerror() translates SRW error codes, as returned
1625 by cql_transform_error(), into human-readable English strings. Used
1626 in yaz-client diagnostics when appropriate.
1628 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1629 converts it into a type-1 query which is sent to the server. This
1630 makes CQL available for use with all Z-servers, as opposed to the tiny
1631 minority that can handle CQL queries themselves.
1633 --- 2.0.2 2003/04/28
1635 New Debian package layout similar to the Redhat Package layout.
1637 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1638 and search result respectively.
1640 --- 2.0.1 2003/04/25
1642 Redhat package is now several packages: libyaz (runtime libraries),
1643 libyaz-devel (development and documentation, and yaz (utility programs).
1644 Package spec file by Morten Bogeskov.
1646 New member 'schema' in struct bend_fetch_rr which the name of requested
1647 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1648 handler MAY set this to reflect the schema of the returned record.
1650 New member 'display_term' in struct scan_entry. GFS now sets member entries
1651 and allocates scan entries to be filled by user scan handler. In previous
1652 version, entries member was allocated by the scan handler. That still works,
1653 but the GFS will ignore member display_term - assuming it was NOT set by
1654 the handler. The fact that the GFS now allocates the entries both allows
1655 for new members and makes a scan handler easier to write.
1657 Fix CQL lex buffer overflow.
1659 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1660 SRU default recordPacking is string.
1662 SRU protocol support for frontend server.
1664 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1666 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1668 Added scan for the ZOOM shell (zoomsh).
1672 * String Identifers for Schemas (Amendment 5).
1673 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1674 Old definition for schema
1675 Odr_oid *schema; /* OPT */
1680 Z_InternationalString *uri;
1681 #define Z_Schema_oid 1
1682 #define Z_Schema_uri 2
1685 * resultCount parameter to Sort Response (Amendment 1).
1686 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1688 Support for SRW 1.0 over HTTP. This is an optional feature and
1689 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1692 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1693 on the same port. SRW SearchRetrieveRequests are mapped
1694 to bend_init,bend_search,bend_fetch,bend_close.
1696 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1698 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1699 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1701 ZOOM connections are SRW based if schem http is used for hostname
1702 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1703 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1705 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1706 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1707 distance=n, order=true/false, relation=le, prox unit=word. If
1708 n is omitted, distance 1 is used.
1710 Fixed problem with C compiler include path in wrong order.
1712 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1713 on Solaris. Patch from Ko van der Sloot.
1715 New MARC decode API. All new functions operate on a yaz_marc_t
1716 handle. The most important new functions are: yaz_marc_create,
1717 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1718 decode and destroy respectively. Decoder can produce formats
1719 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1720 include/yaz/marcdisp.h.
1722 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1723 to UTF-8, UCS-32, wchar_t or Latin-1.
1725 * Prototypes for yaz_iconv_-functions moved to separate header
1726 include/yaz/yaz-iconv.h.
1728 Make a few private functions 'static' in unix.c. This prevents
1729 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1731 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1732 are set when Init Response is received.
1734 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1735 but returns diagnostic set as well.
1737 New function yaz_strerror which is a portable wrapper for
1738 strerror/strerror_r/GetLastMessage.
1740 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1741 is returned for MARC. If type is "oai", then OAI MARC is returned.
1743 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1746 --- 1.9.2 2002/11/26
1748 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1750 Fix bad race conditions on SIGTERM and terminate gracefully in
1753 Move retrieval (data1) module to Zebra since nobody seems to be
1756 Add GRS-1 render for ZOOM using same format as yaz-client.
1758 --- 1.9.1 2002/10/05
1760 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1762 Fix broken ESpec handling in data1 module.
1764 SGML reader parses comments and makes them part of the data1 tree.
1766 Added several type casts so that YAZ compiles as C++ code.
1768 ZOOM didn't handle PDU encoding failures properly.
1770 Added more Bib-1 diagnostics (approved extensions).
1772 GNU configure: better check for iconv.
1774 More portable use of accept, getpeername. Check for socklen_t. Use
1775 int/size_t if socklen_t is not defined.
1779 PQF parser rejects bad queries - including those with extra
1780 characters in them. PQF parser used to silently ignore that.
1781 Cleaner API for PQF added, which allows you to get detailed
1782 error information for bad queries (see yaz/pquery.h).
1784 Fixed bug in ZOOM_record_get for type "database".
1786 Implemented mini iconv library supporting conversions between
1787 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1789 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1791 --- 1.8.9 2002/08/20
1793 Fixed ZOOM C record cache so that preferredRecordSyntax and
1794 elementSetName is used to check for already fetched records.
1796 --- 1.8.8 2002/08/02
1798 Added three members in bend_initrequest structure to facilitate
1799 character set negotiation.
1801 Fixed a bug in frontend server that could cause indefinite
1802 loops under rare conditions.
1804 Revised character set utilities (charneg.h) so that encoding
1805 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1807 For PQF, directive @term <type> sets term type for Scan/Search.
1808 Here <type> is general, string, numeric, null. The term type
1809 is inherited - just like @attr.
1811 New call odr_set_charset that sets character set conversion for
1812 international-strings on a ODR stream. Prototype is:
1813 int odr_set_charset(ODR o, const char *to, const char *from);
1814 The InternationalString is still represented as C string in YAZ
1815 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1816 won't). On the protocol level, you can use any encoding.
1818 Support for UNIX sockets in ZOOM.
1820 Solaris recv sometimes returns errno == ENOENT. It is treated as
1821 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1823 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1824 both client and server. Code by Morten Bogeskov.
1826 --- 1.8.7 2002/05/22
1828 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1829 that they can be used directly from Visual Basic. You must recompile
1830 your windows APP if you're using ZOOM.
1832 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1833 Commands "lang" and "charset" sets language and character set respectively.
1834 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1835 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1837 Attributes from multiple CCL fields may be OR'ed rather than merged
1838 using directive "@field or". Fields are still merged by default -
1839 equivalent to "@field merge".
1841 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1844 Fixed bug in zget for parameter ExtendedServicesResponse.
1848 --- 1.8.6 2002/03/25
1850 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1852 Client displays USR.1:SearchResult-1 (hits per term).
1854 Additional Search Info for search in Generic Frontend Server.
1856 Fixed CCL parsing of "field=s".
1858 WIN32 installer - using the excellent NSIS software from nullsoft.
1860 Fixed CCL parsing of "field = - <number>".
1862 Added function yaz_marc_decode that decodes MARC for line mode
1863 display or XML (similar to that used by JZKit).
1865 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1866 Z39.50. But ISO/ILL was, however.
1868 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1869 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1874 --- 1.8.5 2002/02/03
1876 New YAZ client features: Command completion and new commands:
1877 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1878 Code provided by Jacob Poulsen.
1880 New call oid_trav, that visits all registered OIDs via callback.
1882 Function ZOOM_record_get now returns const char pointer rather than
1883 void pointer. It saves a lot of type casts.
1885 For YAZ client, command "auth" now allows you to set authentication
1886 in IdPass style. It is enabled when three tokens are given - order
1887 is user, group and password.
1889 Fix memory leaks in MARC record handling for ZOOM.
1891 New option for YAZ client, -k <kilobytes> that sets
1892 maximum record size. Similar to -k option for generic frontend
1893 server and yaz-ztest.
1895 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1897 Prefix query parser reports "fail" when bad attribute set is given.
1899 Fix in MARC decoder. Proximity logging. Fix for attribute set
1900 in scan handler for server. Patches by Shigeru Ishida.
1902 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1905 Configure option --with-openssl=<dir> now works when a directory is
1906 specified. Patch provided by Morten Bogeskov.
1908 New option for YAZ client, -u <auth>, that sets authentication.
1910 ZOOM fix: error information was sometimes "missing", since error
1911 was cleared/reset too when it shouldn't.
1913 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1915 --- 1.8.4 2002/01/04
1917 Scan for ZOOM API. New object ZOOM_scanset. New functions
1918 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1919 ZOOM_scanset_destroy.
1921 New ZOOM function, ZOOM_connection_last_event, that returns type
1922 of last event (such as "receive data", "send data", "apdu received",
1925 New ZOOM option, schema, that specifies schema for retrieval.
1927 New CCL feature. Qualifiers can be aliases for one or more
1928 other qualifiers (if more than one is given, OR is used).
1930 ZOOM uses named result sets if target supports it.
1932 Two new YAZ client commands: . (dot, which sources a script of YAZ
1933 client commands), and ! (to execute shell command.). Implemented
1936 Working on Debian packages.
1938 --- 1.8.3 2001/11/19
1940 YAZ client enables named result sets only if target supports it.
1942 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1944 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1945 with key="host" to get same result.
1947 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1948 Function Z3950_resultset_record(s) returns references to records
1949 "owned" by resultset. To become owner use Z3950_record_clone.
1951 Function z_ext_record handles Extended Services. Thanks to
1954 --- 1.8.2 2001/11/12
1956 CCL Parser fix: ignore token comma when dealing with and-lists.
1958 Documentation updates for COMSTACK.
1960 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1961 Changed prototype Z3950_records. For some functions, int parameters
1962 were changed to size_t.
1964 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1967 New MARC decode/display function, marc_display_exl, which properly rejects
1968 non-ISO2709 records. YAZ client uses it.
1970 --- 1.8.1 2001/10/29
1972 Fix bug: local attribute set wasn't set correctly in PQF strings.
1976 * Old Z39.50 codecs no longer supported.
1978 Added ZOOM C binding. See http://zoom.z3950.org/
1980 Renamed states for COMSTACKs to avoid confusion with events.
1982 Implemented cs_look and proper cs_rcvconnect.
1984 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1986 Configure detects POSIX threads on OpenBSD.
1988 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1989 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1991 When error is returned from present handler, non-surrogate diagnostic
1992 is returned in present response (and fetch handler is no longer called).
1994 * Minor adjustments to pquery parser (PQF). Token characters may be
1995 escaped by using backslash (C-style).
1997 PQF parser allows string attribute values to be specified. For @attr,
1998 non-numeric characters after the equal-sign are treated as strings
1999 (e.g. @attr 9=title).
2001 CCL trunction character may be defined (@truncation in file)
2003 * function zget_ExtendedServicesRequest sets waitAction to
2004 waitIfPossible (was wait).
2006 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2009 CCL operator names may be set in field definition files (CCL_bibset).
2010 See ccl/bib1 for an example.
2012 Fixes in ASN.1 compiler for C++ compatibility.
2014 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2015 and "op_or" to avoid conflict with C++.
2017 Fixed problem with GNU readline detection on Redhat 7.0.
2019 Added step-size for Scan backend handler.
2021 Fixed bug that made the frontend server crash when no attribute
2022 set was specified for scan.
2024 Front-end server automatically switches to original working directory
2025 when installed as an NT service. Previously -w had to be specified to
2028 Added extended attributes for retrieval module (data1), so that data1
2029 records carry d1_readXML/SGML attributes. d1_read also supports
2030 null-data rules ( <tag/>)
2032 On UNIX when POSIX threads are available, a separate library libyazthread
2033 is created. Programmers should link with that library and the yaz library
2034 when using threads. The reason for the split was that some applications
2035 on Linux, such as Apache, doesn't work well when using shared objects that
2038 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2039 (or any frontend server) in SSL mode by specifying ssl: followed by
2040 address. Only tested on UNIX.
2042 Added feature for CCL module. Virtual structure s=al or s=ol generates
2043 and-list and or-list respectively instead of phrase search.
2047 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2048 log_mask_str. This was done to avoid name conflicts with other libraries
2049 (such as other PHP extensions).
2051 Added raw OID member for preferred record syntax (request_format_raw)
2052 and returned record syntax (output_format_raw) for backend fetch method.
2054 Config file yaz-config now accepts options so that it returns specific
2055 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2057 Shared library support for UNIX using GNU libtool.
2059 * Modified backend interface. Request/Response struct's replaced by
2060 one read/write C struct. For example bend_fetchrequest and
2061 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2062 Every handler - even search has to be registered in bend_init
2063 handler. This means that the YAZ library no longer refers to
2064 external functions and it makes it possible to make the whole
2065 thing a single DLL/SO.
2067 Added Segment handler for backend server.
2069 Added Zmbol/Zebra administrative functions to YAZ client.
2071 Threaded frontend server on UNIX (when POSIX Threads are available).
2072 Starting the server with option -T enables multi-threading.
2076 Added configure option --enable-comp/disable-comp to control use
2077 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2078 located in sub directory asn.
2080 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2081 in ${exec_prefix}/bin along with the other programs yaz-client and
2084 GNU automake used to maintain makefiles.
2086 Added several OID's.
2088 Changed retrieval module so that we can load records with no abstract
2089 syntax defined. Tagpaths in these records are fully composed of string
2092 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2096 On UNIX, the generated makefile now supports a proper 'make install'.
2097 The prefix can be set via GNU configure to set the install location
2098 (default is /usr/local).
2100 * YAZ programs client and ztest were renamed to yaz-client and
2101 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2102 locations, such as /usr/bin,/usr/local/bin,etc.
2104 * YAZ Header files were moved from include to include/yaz. YAZ Header
2105 files are referred to as include <yaz/log.h> rather than <log.h>.
2106 The YAZ include path (-I ..) is therefore the same as before. Programmers
2107 should update their #include statements or use -Ipath/include/yaz
2108 instead. The main motivation for doing this change is that YAZ header files
2109 can be installed in "standard" locations /usr/include,/usr/local/include
2110 without introducing conflicts, since ALL YAZ header files are stored
2111 in subdirectory yaz (under /usr/include for example).
2113 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2114 rather than project/workspace files. We switched because project files
2115 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2118 Changed name of logging function, logf, to yaz_log, to prevent name
2119 clash with some math-log functions. The YAZ header log.h defines logf
2120 to yaz_log (#define) so there should be no incompatibilities by this
2123 Added bend_start/bend_stop handlers for server. These handler are
2124 called on start/stop of server. For windows they are called whenever
2125 a service is started/stopped.
2127 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2128 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2129 in util/yc.tcl. The auto-generated C code structures are, in a few
2130 cases, incompatible with the old decoders. There are differences in the
2131 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2132 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2133 The preprocessor variable ASN_COMPILED is defined when the compiled
2134 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2135 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2136 wish to use the old encoders/decoders you can specify --disable-yc
2139 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2140 version so that it supports both new - and old version of DB Update
2142 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2143 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2144 change. The name parameter can be set to 0 in which no name is specified
2145 for the construction. The macros odr_implicit and odr_explicit sets name
2146 parameter to zero for the construction involved. New macros
2147 odr_implicit_tag and odr_explicit_tag are similar to the others,
2148 except that a name parameter is added. For programmers' that don't use
2149 ODR they probably only need to change the call to z_APDU and z_External.
2151 Added access control facility by interfacing the TCP wrapper library.
2152 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2153 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2154 name of the daemon and enables the access control as specified in
2155 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2157 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2158 den Dool <H.M.vdnDool@kub.nl>.
2160 Added reference ID parameter to most functions in server API - refer
2161 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2163 Changed name of ccl library to libccl.a (was ccl.a).
2165 Fixed bug in decoder for Explain (Category TargetInfo).
2167 Added support for GNU readline in client. Thanks to Jacob Poulsen
2168 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2170 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2171 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2172 IMPLEMENTATION! This change was made to the development version before
2173 the ZIG decided to retract the amendment. If any users MUST be
2174 compatible with the original Update definition, PLEASE CONTACT US, and
2175 we will include a separate definition corresponding to the old Update
2176 ES. Note that because of the change to the ASN.1 of the
2177 TaskPackageRecordStructure we cannot define a single structure that
2178 will support both versions.
2180 * Added const modifier to buffer parameter for some ODR/BER encoding
2181 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2182 completeWAIS, odr_dumpBER.
2184 Fixed bug in client.c which caused a crash when a scanResponse didn't
2185 contain positionOfTerm.
2187 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2188 * will cause an error in a client if a non-YAZ target sends both a
2189 * list of Scan entries and non-surrogate diagnostics.
2191 Retrieval module enhancements. Tag sets may be typed in the reference
2192 to it. From the .abs-file the "tagset" directive takes a third optional
2193 integer type for the tag set referenced. From a .tag-file the "include"
2194 directive takes a third optional type as well. The old "type" directive
2195 in the tag set itself is still recognized but acts as the default type
2198 Backend interface change. Individual Scan terms returned from bend_scan
2199 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2200 in include/backend.h.
2202 Retrieval module enhancements. Multiple tag sets and attribute sets may
2203 be specified in abstract syntax specs. Revised the error/warning for
2204 logging messages reported by the retrieval module when reading the
2207 Object Identifier system (oid_..) changed. The API is backwards
2208 compatible but the oid-routines now allocates new OID's when needed.
2209 Raw OID's may be specified in oid_getvalbyname.
2211 YAZ now uses GNU configure to generate Makefile(s).
2213 * Minor changes in some of the member names of DeleteResultSetRequest and
2214 DeleteResultSetResponse. See include/proto.h.
2216 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2217 and added member 'languages' in TargetInfo (which was missing).
2219 Changed the way attribute sets are handled in the retrieval
2220 module. These are now cached, just like the abstract syntaxes
2223 Changed YAZ so that it links with compiled ASN.1.
2225 Added Explain-schema definitions and mapping routines. The following
2226 Explain categories have been implemented: AttributeDetails,
2227 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2229 Fixed minor bug in Windows version of Server Library.
2231 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2233 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2235 Added EXTERNAL: UNIverse Resource Report (non-standard).
2237 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2238 ENUMERATED and SET OF.
2240 * Added 'const' to some of the char pointer arguments for the
2241 functions, data1_read_node, data1_getelementbytagname,
2242 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2245 Fixed bug in data1_insert_taggeddata - the last_child member of
2246 parent wasn't initialised.
2248 * Changed data1_read_record and data1_read_node so that the supplied
2249 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2250 doesn't refer to any parts of the "SGML"-buffer.
2252 Fixed bug in server library (Windows version of statserv_remove).
2254 * Changed code so that it compiles as C++. The type definition
2255 of Odr_fun which is a member of Odr_arm was changed. The result is,
2256 that an explicit typecast is needed for the fun pointer when
2257 using Odr_arm - as in:
2258 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2260 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2262 Implemented the new structured date and time definition as approved
2263 by the ZIG. Added schemaId element to the specificTag in Espec-1
2264 (also approved at the last ZIG). Thanks to RVDM.
2266 Added some Object identifiers (RVDM).
2268 Changed the Update Extended Service (RVDM).
2270 Added command "refid" to client which specifies referenceId for
2271 the following requests.
2273 Implemented extended service handling for server. See ztest.c
2274 for an example as well as backend.h. New handlers are registerd
2275 in the Init handler.
2277 * Changed interface for sort in server.
2279 Added new members to statserv_options_block. It allows a server
2280 to read options from another source than just the command line. Thanks
2281 to Charles Woodfield.
2283 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2284 renamed to zboolean. Some C++ compilers complained about the name.
2286 Minor changes to gils.abs. Added index 's' (sort) on title
2287 and date/time-last-modified.
2289 --- 1.4pl2 1998/1/30
2291 Fixed bug in server library regarding inetd mode (-i). This bug
2292 was introduced by release 1.4.
2294 --- 1.4pl1 1998/1/29
2296 Added sort facility in client and backend server interface.
2298 Fixed problem with dependencies in Makefile(s).
2300 Fixed bugs for encoders/decoders of extended services and
2303 Implemented sub-tree feature for schemas. Sub-trees are
2304 referenced in *.abs-files. See explain.abs for an example
2305 of the use of this feature.
2307 Modified bib1.att; local attributes for ANY didn't include
2308 ANY itself (only affects use of the retrieval module).
2310 Fixed bug in plain SGML reader in function data1_read_node:
2311 tags with prefix "var" was incorrectly interpreted as variants.
2313 Added feature "sub-schemas" to enable references to - and definitions
2314 of - group of elements.
2316 * Removed member parent from type data1_element (in data1.h).
2318 Implemented function odr_nullval() that returns the value of
2321 * Removed member num_children from data1_node (in data1.h).
2323 Made NT service interface part of the server library. The
2324 function statserv_main uses the NT service when required and
2325 calls the statserv_start / statserv_close routines.
2327 Routine zget_SearchRequest and zget_PresentRequest fills
2328 resultSetName/Id member with "default" instead of "Default".
2330 Fixed memory leak in server. Request queue member wasn't freed.
2332 Fixed nmem_exit so that memory is freed.
2336 Revised the CCL parser utility to be thread safe.
2338 Added function, oid_ent_to_oid, to replace the function
2339 oid_getoidbyent, which is not thread safe.
2341 * Added nmem_init and nmem_exit to initialize and release
2342 NMEM resources. Function nmem_init should be called once in the
2343 initial thread before NMEM/ODR is used. statserv.c and client.c
2344 have been changed accordingly. The change was necessary to make
2345 NMEM thread safe. The NMEM memory pool is shared amongst threads
2346 in a process. Unix-based applications will still work fine without
2349 Added NT Services interface for the the Z39.50 (statserv) Server.
2350 Refer to the ztest.c source on the usage.
2352 Windows 95/NT port using MSVC5.0. Project files are included in the
2355 * Defined new 'global' handle for the retrieval (data1) system. The
2356 new handled, data1_handle, describes the state of the data1 system.
2357 This handle is passed as first argument to virtually all
2358 data1 related routines. The functions data1_create and data1_destroy
2359 creates and destroys a data1 handle respectively.
2361 Added ODR encode stream member to all backend request structures
2362 init, search, scan etc. This stream should be used to allocate all
2363 memory used for the response when thread safe operation is needed.
2365 Changed the comstack utility, cs_addstr, to be thread safe. The
2366 returned hostname string returned by the function is now part the
2369 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2370 function. The cs_straddr takes a COMSTACK handle as argument, so this
2371 function must be used after cs_create and before bind/connect.
2372 This function is thread safe.
2374 Moved test server to 'ztest' directory - generic server code still
2375 in 'server' directory.
2377 Made prefix query (pquery.c) utility thread safe.
2379 Added new function modifier YAZ_EXPORT to 'export' public DLL
2380 functions when using windows (see include/yconfig.h).
2382 Added definitions to the OID database (util/oid.c) (RVDM).
2384 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2386 Added call to ccl_rpn_delete in client program.
2388 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2389 release of RPN structure.
2391 Added support for C++, headers uses extern "C" for public definitions.
2392 With input from RVDM.
2394 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2395 Thanks to Ronald van der Meer (RVDM).
2397 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2399 Added support for private extensions to the OID database
2400 (oid_setprivateoids()). Thanks to RVDM.
2402 Added optional, physical ANY (key replication)
2404 Fixed null-reference problem in GRS-1 output filter.
2406 Proximity operator added to Prefix Query Format (PQF).
2408 In test client command "base" accepts multiple databases.
2410 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2414 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2416 Smallish bug-fixes in the new encoders/decoders (explain).
2418 Bug fixed in DeleteRequest.
2420 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2422 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2424 Added SOIF syntax (using private OID for now) to retrieval module and client.
2426 Added Update extended service.
2428 Added SearchResult-1 additional info structure.
2430 Added optional CCL (ISO8777) interpreter as separate module. Available
2433 --- 1.2 1996/6/10 (1st anniversary release)
2435 Added Summary record syntax. Lightly tested.
2437 Added OPAC record syntax. Untested.
2439 Added ResourceReport service encoders/decoders. Untested.
2441 Fixed bug in z_Unit - wrong tagging on unitSystem.
2443 Fixed bug in the DiagRecs decoder.
2445 Added options for max PDU size and session timeout to frontend-server.
2447 Added documentation of query-language parsers and other supporting utilities.
2449 [frontend-server] Added Attribute set to the bend_scanrequest API.
2451 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2452 surrogate diagnostics were generated.
2454 [retrieval] Allow multiple local values for attribute.
2456 [retrieval] Allow multiple attributes per element in .abs files. index type.
2458 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2460 --- 1.1pl2 1996/4/10
2462 Minor changes, mostly specific to Zebra's requirements (retrieval)
2466 Repaired bug in frontend server when running multiple listening
2467 endpoints in dynamic mode.
2469 z_External() now won't break if a known, ASN.1 value comes encapsulated
2470 in an octet-string. The value will pass through unmodified in an Odr_oct.
2472 Added a bit of code to the demo client to decode & display
2473 ASN.1-structured records represented in the octet-aligned branch of
2474 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2476 Added z_ext_getentbyref() to the ASN module. Doc updated.
2478 * Completed the SCAN definition in the ASN module. This may break SCAN
2479 code based on older YAZ-versions at compile-time. The fix is easy -
2482 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2483 under the SCAN definition. Remember to initialize this, server-people.
2485 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2486 that this does not extend to ODR and ASN.
2488 Comstack allows insertion of established socket (primarily for
2489 inetd-operation of servers). Doc updated.
2491 Front-end server can now start from the inetd in TCP mode. Doc
2494 --- 1.0pl4 1996/1/24
2498 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2499 the rank and record number.
2501 Adjustments to the frontend server.
2503 Fixed diagnostic BER dumper. It ignored the file argument.
2507 Various changes to retrieval module.
2509 Changed the union discriminators of the protocol files from enums to
2510 ints paired with #defines.
2512 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2515 *Changed operator in the RPN structure to 'roperator', again to avoid a
2518 Fixed problems in Explain decoders/encoders.
2520 --- 1.0pl2 1995/12/6
2522 Memory bug in log module fixed.
2524 --- 1.0pl1 1995/12/5
2526 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2528 Bug in Explain DatabaseInfo module fixed.
2530 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2534 The shift to v1.0 signals that we now consider the *core* functionality
2535 of YAZ reasonably stable (the core being more or less equivalent to
2536 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2537 tested (Explain not at all - though that will happen soonish).
2539 Minor changes to code to support Windows port.
2541 Various minor changes after we're getting to use GRS-1 & co. more.
2543 Added Espec-1 format.
2545 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2546 of the protocol and it cannot be selected when encoding (maps into 'string'
2547 when decoding). Needed to talk to some servers.
2549 Demo client can request simple element set names.
2551 Added Diagnostic Format encoders/decoders.
2553 Added simple Close handling to frontend server (no hooks for resource
2554 reporting yet), and demonstration client.
2556 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2558 --- 1.0b3 1995/08/24
2560 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2561 handled incorrectly when records were requested in the searchResponse. This
2562 will only affect you if you use the frontend-server.
2564 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2565 Test-client will ask for and print GRS1. Ztest will return dummy records
2568 Added Explain encoders/decoders to the service-level API. Untested.
2570 Added Extended Services: Item Order encoders and decoders to the Service-
2571 level API. Untested. We could use a recent copy of the pertinent bits
2572 of the ILL protocol to add those bits.
2574 Added diagnostic format 1 encoders/decoders to the service-level API.
2577 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2578 odr_cons.c, which causes a more correct output.
2580 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2581 was always set to 0 when no records were requested in the searchRequest.
2583 * Added better external-handling. This shouldn't harm old code that
2584 *encodes* externals. It can break code that looks for a
2585 'single-ASN1-type' representation, since those types that are known
2586 are now decoded immediately. Look at the SUTRS sample code in
2587 seshigh.c and client.c. Documentation updated.
2589 Handling of structured records in bend_fetchresponse. Length -1 marks
2590 structured record, type is deduced from format field.
2592 --- 1.0b2 1995/06/27
2593 Fairly quick maintenance release to add SUTRS support.
2595 Fixed handling of SUTRS records in the demonstration client.
2597 * Added format field to the bend_fetchrequest and bend_fetchresponce
2598 structures of the backend API (frontend server). When the record is
2599 returned, the value of the format field is mapped to an OID. The
2600 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2601 of the record. The special value VAL_NONE in the bend_request means
2602 that no specific format was requested by the client. Documentation
2603 updated accordingly. Test server (ztest) will return a fixed dummy
2604 SUTRS record if your client requests SUTRS.
2606 Documentation updated accordingly.
2608 You can now set external libraries and RANLIB support in the top-level
2612 First public release.
