3 yaz-client emits a better message when receiving an unrecognised
8 The show command offered by the zoomsh command now takes a 3d optional
9 parameter type which is what is passed to ZOOM_record. If the type
10 argument is omitted, "render" is used.
12 RPN to CQL conv may use USE string attributes (bug #2978).
14 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
18 Function yaz_xml2query allows a diagnostic element in the PQF XML
19 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
20 code and additional info respectively.
22 The BER BOOLEAN is now the integral type Odr_bool which still happens
23 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
24 typedef'd to Odr_int. This is still an integral 'int', but it may be
25 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
26 ASN-1 compiler as well as programs has been updated to use the new types.
30 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
31 only the bibliographic record was rendered. For type=opac, an OPAC
32 record is only returned if it is present.
34 iconv: small fix for encoding of advancegreek.
36 yaz-client: avoid double display of SRU/SRW records (bug #2798).
38 yaz-client: option auto_reconnect=on really reconnects.
40 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
42 server: avoid null ptr ref for for yaz_poll errors.
44 build: fix RPM build for RHEL 5.3.
46 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
50 Fixed bug #2709: TCP connect returns Invalid argument.
52 Fixed compilation for mingw.
54 Honor charset for raw records (ZOOM_record_get).
56 Fixed use of errno for threaded mode that was seen on Solaris 10.
58 Fixed argument passing with blanks in value for Windows Service.
60 Disable YAZ' own log rotate by default (no 1 GB limit).
61 The variable l_max_size which specifies the log file limit is set to 0
62 (DISABLED): This is due to the fact that YAZ is most often deployed using
63 logrotate. Also YAZ can not perform log rotate because of unsufficient
68 List supported encodings in man page for yaz-iconv.
70 Fixed missing SSL libs for --libs output
72 Re-established OID record syntax application-xml. Nobody should use it
73 but we don't want to change soname because of this symbol being absent.
77 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
79 Added member named_result_sets for init handler struct for the GFS. This
80 allows a server to disable named result sets.
82 Removed OID record syntax application-xml.
84 Added support for rule-based transliterator for ICU wrapper of YAZ.
86 Fixed bug #1902: yaz-icu XML output.
88 Make YAZ checks Emacs friendly.
90 BITSTRING value shows value. Bug #2346.
92 ISO2709 decoding: skip control characters from indicator data.
94 Omit sort key by default in yaz-icu's output.
96 Allow combined single char options (again) for YAZ' options function.
98 Utility yaz-marcdump got option to display YAZ version (-V).
100 Allow YAZ to use ICU 3.4.
102 Added new ICU test case which illustrates removal of diacritics.
104 --- 3.0.41 2008/12/29
106 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
108 --- 3.0.40 2008/12/29
110 For configure, using option --without-xml2 also disables Libxslt/Libexslt
113 Fixed bug #2352: yaz-marcdump crashes for certain record.
115 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
117 Added support for Danmarc2 to UTF-8 conversion.
119 Added support for ISO5426 to UTF-8 conversion.
121 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
122 implementation version.
124 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
126 --- 3.0.38 2008/11/10
128 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
129 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
131 ZOOM C now interprets databaseName option for ZOOM connection as path
134 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
136 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
138 Dummy Libxml2 types no longer defined in headers of YAZ'.
140 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
143 --- 3.0.36 2008/09/26
145 Various ODR chapter fixes.
147 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
149 Added missing source for Windows compilation, mutex.c.
151 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
153 For SRU connections in ZOOM all records up to "count" are now fetched.
155 Fixed crash in generic frontend server (and yaz-ztest) which occurred
156 in Windows due to bad error handling for Libxml2.
158 Added facility for sending arbitrary records (ASN.1 any) using
159 ZOOM C's Extended service update. Patch by Sam Reynolds.
161 New options for ZOOM C's connection, logapdu which makes ZOOM log
164 --- 3.0.34 2008/06/18
166 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
168 --- 3.0.32 2008/06/12
170 Fixed memory violation that could occur when decoding UTF-8. This bug
171 was only present in 3.0.30 of YAZ.
173 --- 3.0.30 2008/06/06
175 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
176 GNU TLS is used by default (if found).
178 yaz-ztest returns OPAC records if a client asks for OPAC.
180 Improved speed of MARC-8 encoding.
182 Added support for lossy and loss-less MARC-8 encoding.
184 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
186 Added new Windows Service wrapper (sc).
188 yaz-client's itemorder command may now send a file.
190 Fixed yaz-marcdump to allow the use of NS prefix for record element.
192 Added new function yaz_log_xml_errors.
194 Allow (but warn) unknown XML attributes in MARCXML parsing.
196 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
198 The UTF-8 to MARC-8 conversion now uses a different set of characters
199 for Greek symbols. Bug #2120.
201 --- 3.0.26 2008/02/21
203 Added yaz_daemon (daemon.h).
205 Fixed bug #2068: pkg-config trouble
207 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
209 --- 3.0.24 2008/01/28
211 Document --with-xml2 option.
213 Added OPAC XML XSD (etc/opacxml.xsd).
215 Allow glob mask for name attribute in retrieval element for the
216 generic frontend server's retrieval facility.
218 Changed yaz_poll_poll to return yaz_poll_except for all returned events
219 except POLLIN/POLLOUT.
221 Fixed error handling in cs_listen. Bug #2037.
223 --- 3.0.22 2008/01/20
225 Fixed version in yaz/yaz-version.h.
227 Fixed bug #2027: Crash when closing connection.
229 Changed configure so that ICU support is only enabled if only ICU
230 and Libxml2 is available (because the ICU chain is XML based).
232 --- 3.0.20 2008/01/15
234 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
235 is built. Only this DLL depends on the ICU runtime.
237 yaz-ziffy is no longer part of YAZ. It is distributed separately by
238 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
240 Changed license of CCL module to 'Revised BSD'. After consultation with
241 remaining members of the original EUROPAGATE consortium, we are re-issuing
242 the CCL module without a separate license. The software was developed by
243 Index Data as part of a research project. The special license was included
244 to help feed usage information back to the project consortium to support
245 project evaluation. At this time, the project consortium has long-since
246 disbanded, and the majority of the original principals have retired. At the
247 same time, we have significantly modified the software during the following
248 years, to the point where very practically no original code remains. To
249 simplify re-use of the software, we have contacted those members of the
250 consortium who could be reached, and agreed to re-issue the module as a
251 proper part of the YAZ package.
253 Tcl scripts uses /usr/bin/tclsh as preferred shell.
255 CQL closer to being version 1.2 compliant. CQL also allows free-form
256 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
259 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
260 bug could make Extended services handling crash in the ZOOM layer. This
261 bug was only present in YAZ 3.0.18.
263 --- 3.0.18 2007/12/19
265 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
268 yaz-marcdump reads and writes collection wrapped records.
270 Handle OPAC for record conversion module.
272 Fixes for ICU wrapper.
274 Allow ICU libs to be controlled with --with-icu .
276 --- 3.0.16 2007/11/12
278 Added yaz_poll which is a wrapper for select/poll. When poll is available
279 and non-buggy, it is used, by yaz_poll . This allows more than 1024
280 sockets to be in use.
282 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
283 functionality through an XML based configuration (ICU chain). This system
284 is useful for search facilities such as Pazpar2 and Zebra that needs to
285 perform tokenization of indexed material. The ICU code in a separate
286 library libyaz3_icu.a.
288 Added HTTP tunnel facility for COMSTACK, bug #1752.
289 This is a facility that allows a Web proxy, such as squid, to tunnel
290 Z39.50 traffic. This facility is "transparent" to must applications
291 using YAZ. It's enabled by using pseudo transport connect: followed by
292 the proxy address, followed by command, then follwed by he regular
293 "virtual" addresss. For example,
294 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
296 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
298 --- 3.0.14 2007/09/21
300 Fixed bad memory reference in ZOOM_record - cuased by member not being
301 initialized. This was a problem only in YAZ 3.0.12.
303 Fixed bug in conversion from MARC to XML: Non-XML characters in control
304 fields were not removed.
306 Changed the way C code is generated from codetables.xml. Made a MARC-8
307 conversion trie for each characterSet section rather than codeTable.
308 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
309 of codetables.xml from Larry Dixson, LOC. Bug #1464.
311 --- 3.0.12 2007/09/12
313 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
314 from ZOOM_record_error).
316 ZOOM C function ZOOM_record_get returns record schema for type="schema".
318 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
320 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
322 Better SRW-to-Bib-1 diagnostic mapping.
324 ZOOM C and yaz-client announces SRU version 1.2 by default.
326 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
329 Fixed in yaz_sru_decode to allow other version than 1.1.
331 --- 3.0.10 2007/08/22
333 Added support for SRU scan for ZOOM.
335 Added support for the use of the older versions or Extended Service
336 Update in ZOOM. To faciliate this, an option "updateVersion" may be
337 set to the version , 1=first, 2=second, 3=third. The third version is
338 what ZOOM C has used so far. And that, obviously, is the default.
340 Added support for CCL queries in Z39.50 queries sent to the GFS (and
341 therefore in Zebra and in SimpleServer-based applications). The new
342 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
343 qualifier file used to transform incoming CCL queries into Type-1 RPN,
344 which is passed into the back-end search callback function.
346 Added support for HTTP Basic authentication in clients: the SRU/W
347 codec encodes the username/password elements of the PDU structure
348 appropriately, and these may be set using the "user" and "password"
349 options in ZOOM-C applications (the same options that are used for
350 Z39.50 authentication).
354 Fixed bug #1208: SSL appears to be broken in ZOOM.
356 Fixed bug #1206: Libxml2 include path weirdness.
358 Added oid_name_to_dotstring.
360 Allow elementSetName to be specified for ZOOM C record update.
362 Allow waitAction to be specified for ZOOM C based for Extended Services.
364 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
365 syntax OID. Bug introduced in YAZ 3 series.
367 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
371 Fixed bug #1157: yaz-client does not read .yazclientrc from current
372 directory. yaz-client now reads commands from file given by option -f
373 if specified; then tries to read .yazclientrc in current directory.
374 Failing that, it reads .yazclientrc from user's home directory.
376 Added support for correlationInfo Note and ID for Record Update via
379 Added yaz-client command querycharset which specifies character set for
380 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
381 (termListAndStartPoint).
383 Charset ISO5428:1984 is an alias for ISO5428-1984.
385 Implemented a way to perform scan in a result set using Z39.50. This
386 is achieved by attaching the result set name in the characterInfo
387 (type InternationalString) of OtherInformation in the Scan Request PDU.
388 The result set is identified in the otherinformation by the new OID:
389 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
390 This allows for scan in result set and faceted search . Zebra did some
391 of this in the APT term using attribute type 8 and value being result
392 set. Using the OtherInformation approach for this is cleaner and easier
393 to work with in proxies and the like. This facility can be used in
394 yaz-client using new command setscan which takes a result set as first
395 argument, start position (APT) as second.
397 Changed decoding of SRU XML packed records to deal with servers that
398 have recordData with XML data with multiple root nodes. Also make
399 comparison for recordPacking case insensitive. Again, one server
400 returns "XML" where others return "xml".
402 For SRU responses allow Content-Type application/xml as well as text/xml.
406 Fixed bug in character set conversion of BER strings. Bug introduced
411 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
413 For OID class, use oid_class consistently.
415 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
418 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
419 character set for bibliographic information interchange". By Giannis Kosmas.
421 Added documentation on new OID API.
425 Changes to generic frontend server interface: added new member
426 'query_charset' for bend_initrequest structure. A backend init handler
427 should set this member to its native character set for query terms.
428 When defined, the frontend server logic will announce this character set
429 to a client if the negotiationModel bit is set by the client. All server
430 implementors are encouraged to specify this. If a backend server does not
431 specify this a warning is issued using yaz_log(YLOG_WARN,..).
433 Added CCL utility to remove terms (stop words) from resulting RPN
434 tree. This is handled by functions with prefix ccl_stop_words_ .
436 New ZOOM C option, "rpnCharset", which allows client-side conversion of
437 terms in RPN queries.
439 Clean-up the CCL API. Moved some internal structures from ccl.h to
440 private header cclp.h. Changed ccl_parser_create so that a Bibset must
441 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
442 This is replaced by ccl_parser_find_str which takes a string instead.
444 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
445 libyaz.la is the core of YAZ except the generic frontend server and
446 does not depend on POSIX threads anymore. libyaz_server.la is the
447 generic frontend server facilities and uses POSIX thread functionality
448 if available. The libyaz.la no longer depends on POSIX threads because
449 the number of global structures is limited. NMEM no longer re-uses blocks
450 between threads ; it simply free's memory immediately but allocates in
451 "large" chunks as usual. We don't expect any performance penalties
452 because of this. The yaz_log system is still using a global log_level so
453 caution must be taken when modifying it with yaz_log_init_.. +
454 yaz_log_mask_str. This, however, should not cause any trouble because
455 these functions are called during initialization of application code
456 anyway. `yaz-config --libs server` returns libs for server applications;
457 `yaz-config --libs` returns libs for non-server applications.
459 New OID database - with public definitions in oid_db.h. Removed old OID
460 database including the head oid.h and definitions such as enum oid_value
461 and struct oident. The new OID database uses the same string names as
462 before but the 'protocol' is gone. There are now only two representations
463 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
464 converts from string to OID; functions with prefix yaz_oid_to_string
465 converts the other way.
467 Change to emit_term() in CQL-to-PQF query translation: when a term has
468 the /regexp relation modifier, do not process it for leading and
469 trailing "^" and "*", which have quite different meanings in regular
472 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
473 write handlers no longer carries a 'last' parameter. This will make
474 yaz_iconv flush "less" characters. A flush is performed by call to
475 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
477 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
478 removed, because function yaz_query_to_wrbuf does the same.
480 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
481 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
483 Deprecated MARC utility functions removed.
485 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
488 Branch split: YAZ_2_1_55_branch
490 --- 2.1.54 2007/03/16
492 Fix to ZOOM-C so that transparent reconnection is properly handled on
493 connections that are in asynchronous mode.
495 Fixed compilation on OpenBSD 4.0.
497 Large strings in GRS-1 records are now properly displayed in yaz-client.
499 Added character conversion support for "advancegreek"; based on patch from
502 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
503 sequence is met. Before the error was not set so it would be unknown.
505 Adjust yaz-marcdump MARC reader so that it skips until record separator
508 --- 2.1.52 2007/03/07
510 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
511 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
512 fd_set structure used as a bitmask for the FDs to be selected on.
514 Using ACX_PTHREAD macro to check for POSIX threads.
516 Fixed have-vsnprintf check.
518 --- 2.1.50 2007/02/23
520 Fixes for configure on BSD. Bug #900.
522 Added snprintf/vsnprintf wrappers for systems that don't have
523 limits (heavens forbid).
525 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
526 created before all previous tasks were completed and removed from the
527 task queue, the new task could be removed by a mistake.
529 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
531 Implemented pass-through CQL-to-PQF conversions. Bug #861.
533 Fixed bug #832: Problem with MARC/charset in yaz-client.
535 Fixed bug #668: save command line history for yaz-client.
537 Fixed bug #830: pkg-config support.
539 --- 2.1.48 2007/01/23
541 Extended ZOOM result set options with two options that may be read by
542 a client: resultSetStatus and presentStatus with values as specified for
544 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
546 Fixed bug #827: Using SSL fails on Debian etch.
548 Fixed bug #826: Weird looking chars for set of MARC records.
550 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
551 that is treated as an ItemOrder with itemRequest being an XML document
552 external. The value of "doc" is the content.
554 Extended the GFS search facility. New member of bend_search_rr
555 'estimated_hit_count' signals that hits is known to be an estmate
556 (higher or lower than real hit count). New member 'partial_resultset'
557 signals that the search was partial (hit count is lower or equal than
558 real hit count). For Z39.50, the information is stored in resultSetStatus
559 member of SearchResponse APDU. For SRU, the information is signalled
560 via SRU diagnostic 59: "Result set created with valid partial results
563 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
565 --- 2.1.46 2007/01/13
567 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
569 Added ZOOM_connection_peek_event.
571 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
572 the following new functions:
573 ZOOM_event_nonblock, ZOOM_connection_process,
574 ZOOM_connection_get_{socket,mask,timeout},
575 ZOOM_connection_fire_event_{timeout,socket}.
576 The existing blocking event handler, ZOOM_event, is a wrapper for the
577 + blocking ZOOM_event_sys_{poll,select}.
579 Implemented function ccl_xml_config which parses XML version of CCL
580 configuration (bug #798).
582 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
584 Added timings utility (yaz/timing.h)
586 --- 2.1.44 2007/01/03
588 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
591 Fixed bug #779: Rotation of apdu.log fails.
593 Fixed for character set conversions:
594 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
595 Honor G1 set in MARC-8 decoding.
597 --- 2.1.42 2006/12/17
599 Fixed bug #775: char conversion does not handle Alternative UTF-8
602 Implemented function yaz_marc_read_line which parses MARC line format
603 records. There is a wealth of formats out there. So far, this function
604 reads line records produced by yaz_marc_write_line.
606 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
607 more generic and easier to remember(!) options: -i format and -o format
608 which specifies input format and output format respectively - where
609 format is one of "marc", "marcxml", "line", "marcxchange".
611 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
612 does not print anything except warnings for records.
614 For yaz-marcdump, added support for MARC split into files (-s) with a given
617 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
618 spec, at http://www.loc.gov/standards/sru/record-update/
619 This has changed the binary layout of the following structs:
620 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
621 bend_update_rr . Patch by Ko van der Sloot.
623 Added GFS utility function bend_assoc_is_alive which returns 1 if
624 association is still alive (client is connected); 0 otherwise (client
625 closed connection). This allows busy servers to stop working for
628 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
629 been a separate piece of software. This version of ziffy has been modified
630 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
632 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
634 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
635 Client code may now interrogate options such as "init_opt_sort" to
636 find out whether the server claims to support various options.
638 --- 2.1.40 2006/11/27
640 Added utilities yaz_{set,get}_esn to set/get element set name from
643 Removed the build of libyazthread.la. The libyaz.so is the threaded version
644 of YAZ and has been so since YAZ 2.1.10.
646 Implemented ZOOM_record_error which returns error information for
647 record (surrogate diagnostic).
649 --- 2.1.38 2006/10/31
651 Updates for SRU Update by Ko van der Sloot:
652 1. Changed name from "operation" to "action"
653 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
654 versions in the code, marked as 'backward compatible'.
655 3. Added diagnostics for SRU Update.
657 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
659 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
661 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
663 For GFS, fixed problem with SRU diagnostic 'First record position out of
664 range' being issued for 0 hits.
666 zoomtst10 part of Windows Build.
668 --- 2.1.36 2006/10/13
670 Implemented yaz_filepath_comp which splits a path into file path
671 components (required by Zebra 2.0.3+).
673 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
674 BSD inspired license until now so this should not have any real impact on
675 anybody. See http://www.opensource.org/licenses/bsd-license.php
677 Fixed bug #687: Missing log lines.
679 Fixed bug #678: CQL to PQF translation does not preserve double-quote
682 Fixed bug #689: SRU diagnostics to be added.
684 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
685 whether a connection is idle (no more work do do).
687 --- 2.1.34 2006/10/04
689 Change type of optval from long to int for invocation of setsockopt with
690 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
692 Added support for specifying the max log file size for the Generic
693 Frontend Server. The size is given with option -r.
695 --- 2.1.32 2006/09/21
697 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
699 --- 2.1.30 2006/09/17
701 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
704 Fixed bug in Generic Frontend Server that could cause a server to stop
705 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
707 For the generic frontend server, the maximum record size is used as maximum
708 size of incoming packages (SRU + Z39.50). The value until was previously
709 only used in Z39.50 Init negotiation and, later, in a session controlled
710 sizes of records returned. This is controlled using -k option. It can be
711 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
713 --- 2.1.28 2006/09/04
715 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
718 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
720 New option for yaz-marcdump -lpos=value which allows setting a portion
721 of MARC header to a certain value.
723 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
725 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
726 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
728 --- 2.1.26 2006/08/15
730 Fixed problem with SRU mode type (soap, get, post) for yaz-client
733 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
735 --- 2.1.24 2006/08/08
737 Fixed MARC ISO2709 encoding routines to deal with character set
740 Minor changes to GFS logging. Database included in search request log
743 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
744 cached/multiple records.
746 Shared libraries are built by default on Unix+configure.
748 Changed cql2pqf transformation to use a different evaluation order. The
749 new order is: always, relation, structure, position, truncation, index
750 and relationModifier. Old order was: always, relation, relationModifier,
751 structure, index, position, truncation. Note that the the latter ones
752 override former ones for identical attributes.. The new scheme means that
753 it is possible to override any existing attribute with a relationModifier.
754 And also that it is possible to override everything for the index rule
755 (except the ones listed in relationModifier). No order is perfect but this
756 one, we believe, covers more real cases.. The "always" should have been
757 called "default", since the attributes there can be overridden with all
760 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
761 compilation phase, but also for yaz-config --cflags output. This allows
762 us to have public headers with Libxml2 stuff in them . It should also,
763 eventually, make Libxml2 checks redundant in packages using YAZ, such
766 --- 2.1.22 2006/06/15
768 Changed SRU update structure bend_update_rr so that SRU diagnostics are
769 stored in uri, message and details.. Previously diagnostics were stored
770 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
771 compatibility.. but he's probably the only one affected, so.
773 Added support for CCL, compiled on the client side, in ZOOM-C. This
774 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
775 input; the resulting query objects can be used for for searching with
776 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
778 YAZ' configure searches for OpenSSL by default.
780 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
781 SL_CTX_use_certificate_file. See
782 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
783 for more info. Thanks to Ko van der Sloot.
785 --- 2.1.20 2006/06/02
787 Bug #600: SRU GET, POST support for yaz-client. Introduced
788 command 'sru' which selects method SOAP/GET/POST.
790 Allow missingValueAction to be specified for the sortspec string -
791 function yaz_sort_spec. By default, the missing value action is null.
792 Use ! to specify "abort". Use = followed by stringvalue to specify default
795 Ensured that Present-handler (if defined) is called in GFS before any call to
796 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
797 searchRetrieve requests.
799 Documentation for YAZ is now based on the Docbook XML/XSLT using
800 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
801 is no longer depending on jade/openjade or docbook-to-man scripts.
802 PDF is no longer part of the distribution - but can optionally be
803 made using DSSSL/jadetex or FOP.
805 Added retrieval handling support in Generic Frontend Server to support
806 conversion between MARC/XML as well as XSLTtransforms. See
807 etc/yazgfs.xml for an example.
809 Added Authentication support to Generic Frontend Server in SRU
810 mode. Authentication using HTTP Basic is supported, as is the use
811 of 'x-username' and 'x-password' parameters in the request itself.
813 Added support for a new character set MARC8s identical to MARC8 except
814 that it converts combined characters to single Unicode characters in the
815 Latin-1 range (when possible).
817 --- 2.1.18 2006/04/24
819 ASN.1 compiler 0.4: generates brief Doxygen file header for
820 generated .h/.c files.
822 Utility yaz_iconv now supports conversion to MARC-8.
824 New facilities for the MARC module. The reading - and writing of
825 content are separate methods for the yaz_marc_t handle. The following
826 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
827 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
828 format). Write functions have prefix yaz_marc_write_.. The existing
829 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
830 available. Removed support for OAI-MARC and simplexml (not the
831 simplexml from PHP5).
833 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
834 to be returned for this connection.
836 --- 2.1.16 2006/03/31
838 Allow multiple languages and charsets to be specified with
839 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
840 negcharset iso-8859-1,utf-8
842 Translation of proximity nodes from CQL into PQF now works.
844 Moved to automake 1.8, 1.9.
846 Added function yaz_log_set_handler which allows a log handler to be
847 installed. This handler will be called for all log messages. Output
848 to file is also produced; but that can be disabled by passing NULL
849 fname to yaz_log_init_file.
851 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
853 For SRW (including GFS), accept application/soap+xml as content-type
856 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
857 produces NO stylesheet reference even if a default stylesheet is specified
860 --- 2.1.14 2006/03/14
862 Updated Windows package to include yazd.dll + yazd.lib for the
863 Development component.
865 If the environment variable YAZ_LOG is set, then it is used as a
866 string indicating the default level of logging to use if not
867 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
868 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
869 used as before. So, for example, to omit warnings from YAZ logging,
872 cql_transform() now map structure and other attributes before indexes,
873 so that index-specific structures and other attributes can override
874 defaults. So now a combination of mapping specifications such as:
876 index.dc.date = 1=date-modified 4=5
877 does the right thing.
879 cql_transform() now also respects the "always" mapping specification,
880 which establishes an initial set of attributes to be used for all
881 terms except where overridden by more specific attributes associated
882 with the index, relation or modifier.
884 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
885 which mode to use; one of "post", "get" or "soap" (SRW, default).
887 Fixes for yaz_iconv routines: changed trie-based character set conversions
888 to use only non-negative values for bit fields due to Sun's C compiler not
889 supporting negative values.
891 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
892 sequences where not read correctly. Fix by Rustam Usmanov.
894 Updated win/makefile to use options, settings which makes things
895 compile with VS C 2005.
897 --- 2.1.12 2006/02/01
899 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
901 In ZOOM socket code, use select instead of poll on MacOSX.
903 ZOOM-C now support client-side compilation of CQL into RPN that is
904 sent to the server, enabling CQL to be used against all Z39.50
905 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
906 ZOOM_query object, and submit it using ZOOM_connection_search().
907 The CQL-to-RPN translation uses a configuration file, the name of
908 which must be specified in the Connection's "cqlfile" option.
910 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
911 function, which takes as its start-term parameter a ZOOM_query object
912 (which may have had either CQL or RPN set into it).
915 --- 2.1.10 2005/11/29
917 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
918 GFS to support this as well. Backend handler, bend_srw_update, does the
919 update work. Code contributed by Ko van der Sloot.
921 Allow retrieval of Search Result-1 information in ZOOM by the use of
922 options that are attached to a result set. ZOOM documentation updated
925 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
926 UTF-8 conversion. Patch by Raj Patel.
928 Added option -m to GFS to control formatting of timestamps in log file.
930 Added 'exit' as synonym for 'quit' in yaz-client
932 Added support for specifying SRW resultSetId + resultSetIdleTime in a
933 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
934 for the new members. Patch by Ko van der Sloot.
936 Added support for SRU POST. It is supported for content-type
937 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
939 Do not build the separate Multi-threaded (MT) library libyazthread.la.
940 Instead make the library libyaz.la multi-threaded. Threading as a whole
941 can still be disabled by configure option --disable-threads. Previosly,
942 with older GLIBCs there were problems with MT libs under Apache. This
943 has now been fixed a long time ago.
945 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
948 CQL module modified to be case insensitive for relations/indexes/operations.
950 Fixed bug in CQL transform code: incorrect value relationModifieder
953 Added 'show all' command for yaz-client which retrieves all results
956 Added new yaz-client, xmles, which takes a (private) OID and
957 a document to be sent as an extended service request.
959 Describe new yaz-client commands wait_response and set_auto_wait.
961 Increase TCP/IP listener backlog from 3 (which I am guessing was
962 copied from the SunOS manual entry way back when) so SOMAXCONN, so
963 that the socket will queue as many incoming connections as it's able
964 to handle ongoing connections. In other words, it will never now
965 refuse a connection that it would be able to handle merely because
966 it's not got around to accepting() enough of the pending connections
967 yet. This is the behaviour anyway under Linux, where the listen()
968 argument is ignored; but not under BSD and on systems such as
969 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
970 YAZ-based servers should now be uniform across operating systems in
973 yaz-marcdump uses 64-bit file access on some systems. This is enabled
974 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
975 This allows yaz-marcdump to read large MARC batches (>2 GB).
977 Modified all YAZ source files - except the source which is auto-generated
978 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
981 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
982 corresponding to the existing *_setl() function. These allow option
983 values containing arbitrary valuues.
985 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
986 ZOOM_resultset_sort() in new applications. Its behaviour is identical
987 except that it returns an indicator of whether or not the sort
988 criterion was accepted (0 for OK, -1 for invalid).
992 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
993 MARC output rather than returning "new" buffer.
995 yaz-client warns about unknown init options.
997 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1001 Added support for SRW sort in Generic Frontend Server. Patch
1002 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1003 sortKeys - or NULL if none is provided.
1005 Fixed bug #307: It was impossible to specify indefinite/no timeout
1006 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1009 Added support for multiple languages and charsets to be specified in
1010 ZOOM. Each charset/language is separated by a blank. If negotiation is
1011 in effect in init-response, Option
1012 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1013 Code based on patch by Vasiliy Osadchuk.
1015 Fixed bug #306: infinite recursion that occurred when calling
1016 yaz_log_level_init as the first call (before other log level or
1019 Fixed bug in scan handling in front end server: if preferred-Position-In-
1020 Response was non-present, a NULL pointer referece was performed.
1022 --- 2.1.4 2005/04/26
1024 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1025 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1026 now defined for all those error codes. So instead of putting 109 in
1027 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1028 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1030 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1033 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1035 Program yaz-client now exits and produces an error message if multiple
1036 Z39.50 servers are specified on the command line (none or one allowed
1039 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1042 --- 2.1.2 2005/03/16
1044 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1046 Fixed bug #272: Preserve spacing for CCL terms.
1048 --- 2.1.0 2005/03/14
1050 Added support for virtual hosts and multiple backend servers for
1051 the YAZ frontend server. The configution is XML based and
1052 support specificition of CQL to RPN mappings and explain information.
1053 See section "Virtual Hosts" in the YAZ manual.
1055 Extended OPAC display utility. OPAC display utility renders
1056 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1057 to supplement yaz_marc_decode_wrbuf.
1059 Fixed a bug in MARC decoder that could caused it to crash for some
1060 invalid MARC records. More diagnostics and warnings where added in
1061 XML output (warnings, etc are stored in comments).
1063 --- 2.0.34 2005/02/08
1065 Fixes for UNIX domain sockets. Bug #261.
1067 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1069 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1070 Added yaz_marc_subfield_str which defines subfield lead string which is
1071 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1072 yaz_marc_endline_str which defines end of fields string used in
1073 YAZ_MARC_LINE format. Default string is newline.
1075 Experimental support for MarcXChange. This format can be produced
1076 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1077 http://www.bs.dk/standards/MarcXchange.xsd
1079 Added yaz-client commands scansize that sets maximum number of
1080 entries to be returned by scan.
1082 --- 2.0.32 2005/01/11
1084 Added support for SRW scan in yaz-client and Generic Frontend Server.
1086 * Added whereInList member to SRW Scan Term.
1088 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1090 Fixed NMEM system to return aligned blocks on the smallest boundaries
1091 that are suitably aligned for all possible types on the particular
1092 architecture YAZ is being built for.
1094 --- 2.0.30 2005/01/04
1096 Fixed numerious warnings that was issued with newer versions of GCC.
1098 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1099 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1102 Make YAZ Generic Frontend Server slightly faster.
1104 Enhance (and reduce) logging for Generic Frontend Server.
1106 Revert YAZ log system so that it flushes every write operation
1107 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1109 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1110 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1111 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1112 will effectively disable old definitions.
1114 --- 2.0.28 2004/11/09
1116 Added yaz_log_time_format which specifies log format using
1119 Added yaz_log_module_level which returns mask for a module. Value
1120 is non-zero mask a if module is enabled; zero if disabled.
1122 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1123 in include/yaz/cql.h.
1125 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1127 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1129 Fixed bug #172: RPM builds does not enable SSL.
1131 Doxyfile.in part of dist. Doxyfile generated by configure.
1133 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1134 are given and the corresponding component does not exist.
1136 Extend CCL documentation in YAZ reference. Describe r=r.
1138 --- 2.0.26 2004/10/01
1140 Fixed MARC->MARCXML conversion to properly deal with
1141 fields, subfields, indicators having non-ASCII characters.
1143 Fixed MARC->MARCXML conversion so that ASCII control characters
1144 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1147 Added YAZ GFS support for conversion from Z39.50 surrogate
1148 diagnostics to SRW surrogate diagnostics.
1150 Bug fix: YAZ GFS did not return schema in explainResponse.
1152 --- 2.0.25 2004/09/30
1154 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1155 now converts recordSchema to elementSetName as well as schema URI.
1157 Fixed bug in COMSTACK that prevented HTTP request packages from being
1160 --- 2.0.24 2004/09/29
1162 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1163 does not require white-space before and after the dash in a range, e.g.
1164 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1167 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1168 due to new GCC removing "redundant" code.
1170 Added yaz-client commands scanpos and scanstep that sets preferred
1171 position and step-size for scan.
1173 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1175 Added CCL utility ccl_qual_buf which parses one or more CCL
1176 spec lines in a buffer.
1178 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1179 of name and value - ignoring empty lines and comments.
1181 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1183 Added odr_get_element_path which returns current element path for an
1184 ODR handle. This utility is useful in error handling or user-defined
1187 Added ODR_PRINT utility odr_set_stream which is is a more generic
1188 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1189 to a write function and pointer to close function. The close function - if
1190 non-NULL - will be called during odr_destroy.
1192 Fixed bug in CCL parser where truncation char was not removed from
1193 right side when truncation=both was in effect.
1195 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1198 --- 2.0.23 2004/08/11
1200 Fix buffer overrun in CQL parser when dealing with proximity (%).
1202 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1203 to UTF-8/UCS conversion is now only based on codetables.xml.
1205 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1207 --- 2.0.22 2004/08/06
1209 Add support for more "commit changes" in ZOOM (uses Extended Services).
1211 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1214 Yet another small fix for configure of SSL.
1216 --- 2.0.21 2004/05/14
1218 Fix SSL libs for configure when --with-openssl=DIR is given.
1220 --- 2.0.20 2004/05/10
1222 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1224 SSL comstack now uses yaz.pem certificate file on server side
1225 by default. Certificate filename can be configured by calling
1226 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1228 Fix bug regarding multiple calls to ZOOM_connection_connect.
1230 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1232 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1233 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1235 ZOOM now allows inspection of X509 peer certificate for verification.
1236 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1238 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1239 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1240 as "modular" but it simplifies things.
1242 Added cs_get_peer_certificate to that returns peer X509 PEM.
1244 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1245 NULL if SSL is unavailable.
1247 Documentation about MARC decoding tools.

1251 --- 2.0.19 2004/03/30
1253 Rename CHANGELOG to NEWS to follow GNU style packing.
1255 Fix bug with missing initialization of member in init_diagnostics.
1256 This bug affects threaded version of GFS server.
1258 --- 2.0.18 2004/03/20
1260 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1263 Ensure zlib.dll is packed with Windows install.
1265 --- 2.0.17 2004/03/17
1267 Fix encoding of xsd:string to use text instead of CDATA.
1269 Fix endless loop in CQL parser with unbalanced ".
1271 Use a more compact way to store MARC-8 conversion tables.
1273 --- 2.0.16 2004/03/16 Debian only
1275 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1278 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1283 --- 2.0.15 2004/03/01
1285 Another fix for decoding of XML packed records.
1287 --- 2.0.14 2004/02/25
1289 Fixes for Chunked encoding. White space not ignored after length spec.
1291 Update NS and use default NS for SRW diagnostic elements.
1293 --- 2.0.13 2004/02/23
1295 Implement ZOOM_resultset_cache_reset which resets record cache.
1297 Implement ZOOM_resultset_sort which sorts a result set.
1299 Implement chunked HTTP transfer.
1301 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1303 --- 2.0.12 2004/02/16
1305 Added member 'schema' to bend_explain_rr structure so that backend
1306 can specify explain record identifier. Defaults to Zeerex 2.0.
1308 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1310 --- 2.0.11 2004/02/16
1312 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1315 Added init command for yaz-client which sends "extra" init request.
1317 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1318 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1320 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1322 Make ZOOM error code for "invalid query".
1324 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1326 --- 2.0.10 2004/02/05
1328 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1331 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1333 Added option -p <file> to make Generic Frontend Server to write PID file.
1335 Added option -D to put Generic Frontend Server in background on its own.
1337 Make ZOOM C recognize option "password". If unset, "pass" is used
1338 (for backwards compatibility).
1340 Fixed a bug in Generic Frontend Server that could make it crash if a
1341 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1344 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1345 Must be issued before open, in order to be in effect.
1347 --- 2.0.9-6 2004/01/12 Debian/Windows
1349 Make the SRU server more picky WRT unknown params, etc.
1351 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1353 New YAZ client command, options, that sets Z39.50 options.
1355 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1356 options from a string of tokens (one token for each option bit).
1358 Update SRW diagnostic code messages.
1360 --- 2.0.9-5 2004/01/07 Debian/Windows
1362 Handle user defined stylesheet for SRW/SRU.
1364 --- 2.0.9-4 2004/01/06 Debian/Windows
1366 Fix bug in decoding of Content-Length.
1368 --- 2.0.9-3 2004/01/06 Debian/Windows
1370 Fix a bug with decoding of XML packed records.
1372 --- 2.0.9-2 2004/01/05 Debian only
1374 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1376 Fix bug in SRW/SRU diagnostics decoding.
1378 --- 2.0.9 2004/01/05
1380 Fixed bug in Generic Frontend Server which could drop records exceeding
1381 preferred message size. Reported and fixed by Irina Dijour.
1383 Fixed calculation of package size for structured records in Generic
1384 Frontend Server. Reported and fixed by Irina Dijour.
1386 Fixed namespace for SRW/SRU diagnostics.
1388 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1390 --- 2.0.8 2003/12/22
1392 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1393 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1396 CQL changes to reflect recent changes to the specification:
1397 * Documentation talks about context sets instead of index sets.
1398 * Documentation talks about indexes instead of qualifiers.
1399 * The CQL-to-PQF transformer's configuration file now uses
1400 "index.set.name = <attributes>" instead of the old form
1401 "qualifier.set.name = <attributes>". (Both forms are still
1402 understood but the latter is deprecated.)
1403 * CQL terms with no explicit index specified are now interpreted as
1404 cql.serverChoice instead of srw.serverChoice (which of course
1405 behaves exactly the same.)
1407 --- 2.0.7 2003/12/16
1409 MARC conversion can now generate ISO2709 output in another
1410 character set. yaz-marcdump uses this facility if you invoke it
1413 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1414 functions from there can be used from C++.
1416 --- 2.0.6 2003/12/04
1418 Frontend server now transfers memory from decoded packages to stream
1421 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1422 references to show up.
1424 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1425 the ZOOM Abstract API. The older names for the same options are still
1426 also supported for the benefit of old applications.
1428 ZOOM-C supports "implementationId" and "implementationVersion" options
1429 to go along with "implementationName". These allow the user code to
1430 specify identification strings to be sent to servers.
1431 Add OID for the new ExtLite attribute set.
1433 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1434 as requested/supplid by Ere Maijala <ere@atp.fi>
1436 For generic frontend server, reverse the order of
1437 "toolkit-supplied / application-supplied" strings sent as implementationId,
1438 Name and Version. Also, remove the spaces around the slash. This brings
1439 the GFS in line with the behaviour of ZOOM-C on the client side.
1441 Add function ZOOM_scanset_display_term.
1443 yaz-client shows scan displayTerm if present.
1445 Utility yaz-iconv is now installed by default along with the man page
1448 Extend configure check for OpenSSL to use pkg-config where available (such
1451 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1452 server to specify uid/gid/mask for socket using the format
1453 unix:[user=uid,][group=gid,][umask=mask,]file=path
1454 If file= is omitted the existing format is assumed, e.g.
1456 in which case the mask is 0666 (rw for everybody).
1458 Major restructure of YAZ source. All source in libyaz is in src directory.
1459 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1460 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1462 Added man page for utility yaz-marcdump (used to be called marcdump).
1463 yaz-marcdump is installed by 'make install'.
1465 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1466 of incoming package failed.
1468 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1470 Change prototype of odr_perror: add const to message string.
1472 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1474 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1475 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1476 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1477 DNS lookup. There should not be any compatibility problems with this
1478 assuming that blocking=1 or 0 is used.
1480 Fix bad reference in UNIX comstack in function cs_addrstr.
1482 Fix for compilation on AIX.
1484 The generic front-end server (server/seshigh.c) now supports returning
1485 Init diagnostics to the client in User-information-field, in
1486 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1489 --- 2.0.4 2003/09/04
1491 Allow any CQL relation (not just all,any,exact,scr).
1493 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1494 that features the same UI.
1496 Implemented command update0 in YAZ client which is equivalent to
1497 update but uses old of Ext Update ASN.1.
1499 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1500 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1501 Previously no OID was used for this info.
1503 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1504 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1505 returns 'malformed search term' otherwise.
1507 SortResponse member resultCount now set to NULL in sort handler of
1510 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1513 Add three new utility functions for translating OIDs between various
1514 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1515 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1516 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1517 char *oid_to_dotstring(const int *oid, char *oidbuf);
1518 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1520 Reverted modifications for ES Update definition for z_IU0Update
1521 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1522 is back to YAZ 2.0.2.
1524 String value attributes for CCL parser.
1526 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1527 which their FirstSearch server returns in Init responses, sometimes
1528 carrying useful diagnostic information when Init fails. This has the
1529 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1530 "z39.50/oclcui.asn", where its definition is somewhat different from
1531 what OCLC document on their web-site, as required to interoperate with
1534 Support for anonymous authentication in yaz-client. Use the command
1537 * Fix the OID of the Index Data-local "admin" Extended Service from
1538 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1539 the 1000, which indicates a locally-defined OID, was a mistake.
1541 --- 2.0.3 2003/06/20
1543 Fix CCL directive @case handling so that it affects string match for
1544 both CCL keywords and qualifiers.
1546 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1547 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1548 Decoder has been updated with ASN.1 changes as listed in
1549 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1550 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1551 z_IUUpdate, remains unchanged.
1553 ZOOM_record_get may now return a record in a specific character set.
1554 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1555 "from" is the character set of record as returned by target. "to" is
1556 the character set to be returned. If omitted, "to" is UTF-8.
1558 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1560 New ODR utility, odr_getelement, which returns name of element for
1561 which encoding/decoding failed.
1563 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1564 in cases where a required element was omitted.
1566 Bug fix: some MARC8 sequences were not converted.
1568 New ZOOM option "step" which specifies number of records to be
1569 retrieved in one chunk. Used in conjunction with "start" and "count".
1571 SRW support for yaz-client. Use scheme http: to use it, e.g.
1574 yaz-client no longer does (un)intelligent character set conversions
1575 by default. Can be enabled with charset and marc_charset commands.
1577 xmalloc trace fix for 64-bit systems such as DEC alpha.
1579 Solaris 2.6 compile fix.
1581 New function, cql_strerror() translates SRW error codes, as returned
1582 by cql_transform_error(), into human-readable English strings. Used
1583 in yaz-client diagnostics when appropriate.
1585 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1586 converts it into a type-1 query which is sent to the server. This
1587 makes CQL available for use with all Z-servers, as opposed to the tiny
1588 minority that can handle CQL queries themselves.
1590 --- 2.0.2 2003/04/28
1592 New Debian package layout similar to the Redhat Package layout.
1594 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1595 and search result respectively.
1597 --- 2.0.1 2003/04/25
1599 Redhat package is now several packages: libyaz (runtime libraries),
1600 libyaz-devel (development and documentation, and yaz (utility programs).
1601 Package spec file by Morten Bogeskov.
1603 New member 'schema' in struct bend_fetch_rr which the name of requested
1604 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1605 handler MAY set this to reflect the schema of the returned record.
1607 New member 'display_term' in struct scan_entry. GFS now sets member entries
1608 and allocates scan entries to be filled by user scan handler. In previous
1609 version, entries member was allocated by the scan handler. That still works,
1610 but the GFS will ignore member display_term - assuming it was NOT set by
1611 the handler. The fact that the GFS now allocates the entries both allows
1612 for new members and makes a scan handler easier to write.
1614 Fix CQL lex buffer overflow.
1616 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1617 SRU default recordPacking is string.
1619 SRU protocol support for frontend server.
1621 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1623 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1625 Added scan for the ZOOM shell (zoomsh).
1629 * String Identifers for Schemas (Amendment 5).
1630 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1631 Old definition for schema
1632 Odr_oid *schema; /* OPT */
1637 Z_InternationalString *uri;
1638 #define Z_Schema_oid 1
1639 #define Z_Schema_uri 2
1642 * resultCount parameter to Sort Response (Amendment 1).
1643 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1645 Support for SRW 1.0 over HTTP. This is an optional feature and
1646 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1649 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1650 on the same port. SRW SearchRetrieveRequests are mapped
1651 to bend_init,bend_search,bend_fetch,bend_close.
1653 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1655 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1656 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1658 ZOOM connections are SRW based if schem http is used for hostname
1659 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1660 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1662 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1663 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1664 distance=n, order=true/false, relation=le, prox unit=word. If
1665 n is omitted, distance 1 is used.
1667 Fixed problem with C compiler include path in wrong order.
1669 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1670 on Solaris. Patch from Ko van der Sloot.
1672 New MARC decode API. All new functions operate on a yaz_marc_t
1673 handle. The most important new functions are: yaz_marc_create,
1674 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1675 decode and destroy respectively. Decoder can produce formats
1676 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1677 include/yaz/marcdisp.h.
1679 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1680 to UTF-8, UCS-32, wchar_t or Latin-1.
1682 * Prototypes for yaz_iconv_-functions moved to separate header
1683 include/yaz/yaz-iconv.h.
1685 Make a few private functions 'static' in unix.c. This prevents
1686 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1688 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1689 are set when Init Response is received.
1691 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1692 but returns diagnostic set as well.
1694 New function yaz_strerror which is a portable wrapper for
1695 strerror/strerror_r/GetLastMessage.
1697 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1698 is returned for MARC. If type is "oai", then OAI MARC is returned.
1700 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1703 --- 1.9.2 2002/11/26
1705 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1707 Fix bad race conditions on SIGTERM and terminate gracefully in
1710 Move retrieval (data1) module to Zebra since nobody seems to be
1713 Add GRS-1 render for ZOOM using same format as yaz-client.
1715 --- 1.9.1 2002/10/05
1717 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1719 Fix broken ESpec handling in data1 module.
1721 SGML reader parses comments and makes them part of the data1 tree.
1723 Added several type casts so that YAZ compiles as C++ code.
1725 ZOOM didn't handle PDU encoding failures properly.
1727 Added more Bib-1 diagnostics (approved extensions).
1729 GNU configure: better check for iconv.
1731 More portable use of accept, getpeername. Check for socklen_t. Use
1732 int/size_t if socklen_t is not defined.
1736 PQF parser rejects bad queries - including those with extra
1737 characters in them. PQF parser used to silently ignore that.
1738 Cleaner API for PQF added, which allows you to get detailed
1739 error information for bad queries (see yaz/pquery.h).
1741 Fixed bug in ZOOM_record_get for type "database".
1743 Implemented mini iconv library supporting conversions between
1744 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1746 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1748 --- 1.8.9 2002/08/20
1750 Fixed ZOOM C record cache so that preferredRecordSyntax and
1751 elementSetName is used to check for already fetched records.
1753 --- 1.8.8 2002/08/02
1755 Added three members in bend_initrequest structure to facilitate
1756 character set negotiation.
1758 Fixed a bug in frontend server that could cause indefinite
1759 loops under rare conditions.
1761 Revised character set utilities (charneg.h) so that encoding
1762 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1764 For PQF, directive @term <type> sets term type for Scan/Search.
1765 Here <type> is general, string, numeric, null. The term type
1766 is inherited - just like @attr.
1768 New call odr_set_charset that sets character set conversion for
1769 international-strings on a ODR stream. Prototype is:
1770 int odr_set_charset(ODR o, const char *to, const char *from);
1771 The InternationalString is still represented as C string in YAZ
1772 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1773 won't). On the protocol level, you can use any encoding.
1775 Support for UNIX sockets in ZOOM.
1777 Solaris recv sometimes returns errno == ENOENT. It is treated as
1778 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1780 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1781 both client and server. Code by Morten Bogeskov.
1783 --- 1.8.7 2002/05/22
1785 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1786 that they can be used directly from Visual Basic. You must recompile
1787 your windows APP if you're using ZOOM.
1789 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1790 Commands "lang" and "charset" sets language and character set respectively.
1791 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1792 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1794 Attributes from multiple CCL fields may be OR'ed rather than merged
1795 using directive "@field or". Fields are still merged by default -
1796 equivalent to "@field merge".
1798 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1801 Fixed bug in zget for parameter ExtendedServicesResponse.
1805 --- 1.8.6 2002/03/25
1807 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1809 Client displays USR.1:SearchResult-1 (hits per term).
1811 Additional Search Info for search in Generic Frontend Server.
1813 Fixed CCL parsing of "field=s".
1815 WIN32 installer - using the excellent NSIS software from nullsoft.
1817 Fixed CCL parsing of "field = - <number>".
1819 Added function yaz_marc_decode that decodes MARC for line mode
1820 display or XML (similar to that used by JZKit).
1822 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1823 Z39.50. But ISO/ILL was, however.
1825 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1826 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1828 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1829 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1831 --- 1.8.5 2002/02/03
1833 New YAZ client features: Command completion and new commands:
1834 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1835 Code provided by Jacob Poulsen.
1837 New call oid_trav, that visits all registered OIDs via callback.
1839 Function ZOOM_record_get now returns const char pointer rather than
1840 void pointer. It saves a lot of type casts.
1842 For YAZ client, command "auth" now allows you to set authentication
1843 in IdPass style. It is enabled when three tokens are given - order
1844 is user, group and password.
1846 Fix memory leaks in MARC record handling for ZOOM.
1848 New option for YAZ client, -k <kilobytes> that sets
1849 maximum record size. Similar to -k option for generic frontend
1850 server and yaz-ztest.
1852 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1854 Prefix query parser reports "fail" when bad attribute set is given.
1856 Fix in MARC decoder. Proximity logging. Fix for attribute set
1857 in scan handler for server. Patches by Shigeru Ishida.
1859 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1862 Configure option --with-openssl=<dir> now works when a directory is
1863 specified. Patch provided by Morten Bogeskov.
1865 New option for YAZ client, -u <auth>, that sets authentication.
1867 ZOOM fix: error information was sometimes "missing", since error
1868 was cleared/reset too when it shouldn't.
1870 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1872 --- 1.8.4 2002/01/04
1874 Scan for ZOOM API. New object ZOOM_scanset. New functions
1875 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1876 ZOOM_scanset_destroy.
1878 New ZOOM function, ZOOM_connection_last_event, that returns type
1879 of last event (such as "receive data", "send data", "apdu received",
1882 New ZOOM option, schema, that specifies schema for retrieval.
1884 New CCL feature. Qualifiers can be aliases for one or more
1885 other qualifiers (if more than one is given, OR is used).
1887 ZOOM uses named result sets if target supports it.
1889 Two new YAZ client commands: . (dot, which sources a script of YAZ
1890 client commands), and ! (to execute shell command.). Implemented
1893 Working on Debian packages.
1895 --- 1.8.3 2001/11/19
1897 YAZ client enables named result sets only if target supports it.
1899 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1901 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1902 with key="host" to get same result.
1904 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1905 Function Z3950_resultset_record(s) returns references to records
1906 "owned" by resultset. To become owner use Z3950_record_clone.
1908 Function z_ext_record handles Extended Services. Thanks to
1911 --- 1.8.2 2001/11/12
1913 CCL Parser fix: ignore token comma when dealing with and-lists.
1915 Documentation updates for COMSTACK.
1917 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1918 Changed prototype Z3950_records. For some functions, int parameters
1919 were changed to size_t.
1921 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1924 New MARC decode/display function, marc_display_exl, which properly rejects
1925 non-ISO2709 records. YAZ client uses it.
1927 --- 1.8.1 2001/10/29
1929 Fix bug: local attribute set wasn't set correctly in PQF strings.
1933 * Old Z39.50 codecs no longer supported.
1935 Added ZOOM C binding. See http://zoom.z3950.org/
1937 Renamed states for COMSTACKs to avoid confusion with events.
1939 Implemented cs_look and proper cs_rcvconnect.
1941 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1943 Configure detects POSIX threads on OpenBSD.
1945 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1946 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1948 When error is returned from present handler, non-surrogate diagnostic
1949 is returned in present response (and fetch handler is no longer called).
1951 * Minor adjustments to pquery parser (PQF). Token characters may be
1952 escaped by using backslash (C-style).
1954 PQF parser allows string attribute values to be specified. For @attr,
1955 non-numeric characters after the equal-sign are treated as strings
1956 (e.g. @attr 9=title).
1958 CCL trunction character may be defined (@truncation in file)
1960 * function zget_ExtendedServicesRequest sets waitAction to
1961 waitIfPossible (was wait).
1963 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1966 CCL operator names may be set in field definition files (CCL_bibset).
1967 See ccl/bib1 for an example.
1969 Fixes in ASN.1 compiler for C++ compatibility.
1971 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1972 and "op_or" to avoid conflict with C++.
1974 Fixed problem with GNU readline detection on Redhat 7.0.
1976 Added step-size for Scan backend handler.
1978 Fixed bug that made the frontend server crash when no attribute
1979 set was specified for scan.
1981 Front-end server automatically switches to original working directory
1982 when installed as an NT service. Previously -w had to be specified to
1985 Added extended attributes for retrieval module (data1), so that data1
1986 records carry d1_readXML/SGML attributes. d1_read also supports
1987 null-data rules ( <tag/>)
1989 On UNIX when POSIX threads are available, a separate library libyazthread
1990 is created. Programmers should link with that library and the yaz library
1991 when using threads. The reason for the split was that some applications
1992 on Linux, such as Apache, doesn't work well when using shared objects that
1995 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1996 (or any frontend server) in SSL mode by specifying ssl: followed by
1997 address. Only tested on UNIX.
1999 Added feature for CCL module. Virtual structure s=al or s=ol generates
2000 and-list and or-list respectively instead of phrase search.
2004 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2005 log_mask_str. This was done to avoid name conflicts with other libraries
2006 (such as other PHP extensions).
2008 Added raw OID member for preferred record syntax (request_format_raw)
2009 and returned record syntax (output_format_raw) for backend fetch method.
2011 Config file yaz-config now accepts options so that it returns specific
2012 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2014 Shared library support for UNIX using GNU libtool.
2016 * Modified backend interface. Request/Response struct's replaced by
2017 one read/write C struct. For example bend_fetchrequest and
2018 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2019 Every handler - even search has to be registered in bend_init
2020 handler. This means that the YAZ library no longer refers to
2021 external functions and it makes it possible to make the whole
2022 thing a single DLL/SO.
2024 Added Segment handler for backend server.
2026 Added Zmbol/Zebra administrative functions to YAZ client.
2028 Threaded frontend server on UNIX (when POSIX Threads are available).
2029 Starting the server with option -T enables multi-threading.
2033 Added configure option --enable-comp/disable-comp to control use
2034 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2035 located in sub directory asn.
2037 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2038 in ${exec_prefix}/bin along with the other programs yaz-client and
2041 GNU automake used to maintain makefiles.
2043 Added several OID's.
2045 Changed retrieval module so that we can load records with no abstract
2046 syntax defined. Tagpaths in these records are fully composed of string
2049 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2053 On UNIX, the generated makefile now supports a proper 'make install'.
2054 The prefix can be set via GNU configure to set the install location
2055 (default is /usr/local).
2057 * YAZ programs client and ztest were renamed to yaz-client and
2058 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2059 locations, such as /usr/bin,/usr/local/bin,etc.
2061 * YAZ Header files were moved from include to include/yaz. YAZ Header
2062 files are referred to as include <yaz/log.h> rather than <log.h>.
2063 The YAZ include path (-I ..) is therefore the same as before. Programmers
2064 should update their #include statements or use -Ipath/include/yaz
2065 instead. The main motivation for doing this change is that YAZ header files
2066 can be installed in "standard" locations /usr/include,/usr/local/include
2067 without introducing conflicts, since ALL YAZ header files are stored
2068 in subdirectory yaz (under /usr/include for example).
2070 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2071 rather than project/workspace files. We switched because project files
2072 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2075 Changed name of logging function, logf, to yaz_log, to prevent name
2076 clash with some math-log functions. The YAZ header log.h defines logf
2077 to yaz_log (#define) so there should be no incompatibilities by this
2080 Added bend_start/bend_stop handlers for server. These handler are
2081 called on start/stop of server. For windows they are called whenever
2082 a service is started/stopped.
2084 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2085 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2086 in util/yc.tcl. The auto-generated C code structures are, in a few
2087 cases, incompatible with the old decoders. There are differences in the
2088 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2089 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2090 The preprocessor variable ASN_COMPILED is defined when the compiled
2091 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2092 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2093 wish to use the old encoders/decoders you can specify --disable-yc
2096 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2097 version so that it supports both new - and old version of DB Update
2099 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2100 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2101 change. The name parameter can be set to 0 in which no name is specified
2102 for the construction. The macros odr_implicit and odr_explicit sets name
2103 parameter to zero for the construction involved. New macros
2104 odr_implicit_tag and odr_explicit_tag are similar to the others,
2105 except that a name parameter is added. For programmers' that don't use
2106 ODR they probably only need to change the call to z_APDU and z_External.
2108 Added access control facility by interfacing the TCP wrapper library.
2109 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2110 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2111 name of the daemon and enables the access control as specified in
2112 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2114 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2115 den Dool <H.M.vdnDool@kub.nl>.
2117 Added reference ID parameter to most functions in server API - refer
2118 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2120 Changed name of ccl library to libccl.a (was ccl.a).
2122 Fixed bug in decoder for Explain (Category TargetInfo).
2124 Added support for GNU readline in client. Thanks to Jacob Poulsen
2125 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2127 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2128 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2129 IMPLEMENTATION! This change was made to the development version before
2130 the ZIG decided to retract the amendment. If any users MUST be
2131 compatible with the original Update definition, PLEASE CONTACT US, and
2132 we will include a separate definition corresponding to the old Update
2133 ES. Note that because of the change to the ASN.1 of the
2134 TaskPackageRecordStructure we cannot define a single structure that
2135 will support both versions.
2137 * Added const modifier to buffer parameter for some ODR/BER encoding
2138 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2139 completeWAIS, odr_dumpBER.
2141 Fixed bug in client.c which caused a crash when a scanResponse didn't
2142 contain positionOfTerm.
2144 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2145 * will cause an error in a client if a non-YAZ target sends both a
2146 * list of Scan entries and non-surrogate diagnostics.
2148 Retrieval module enhancements. Tag sets may be typed in the reference
2149 to it. From the .abs-file the "tagset" directive takes a third optional
2150 integer type for the tag set referenced. From a .tag-file the "include"
2151 directive takes a third optional type as well. The old "type" directive
2152 in the tag set itself is still recognized but acts as the default type
2155 Backend interface change. Individual Scan terms returned from bend_scan
2156 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2157 in include/backend.h.
2159 Retrieval module enhancements. Multiple tag sets and attribute sets may
2160 be specified in abstract syntax specs. Revised the error/warning for
2161 logging messages reported by the retrieval module when reading the
2164 Object Identifier system (oid_..) changed. The API is backwards
2165 compatible but the oid-routines now allocates new OID's when needed.
2166 Raw OID's may be specified in oid_getvalbyname.
2168 YAZ now uses GNU configure to generate Makefile(s).
2170 * Minor changes in some of the member names of DeleteResultSetRequest and
2171 DeleteResultSetResponse. See include/proto.h.
2173 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2174 and added member 'languages' in TargetInfo (which was missing).
2176 Changed the way attribute sets are handled in the retrieval
2177 module. These are now cached, just like the abstract syntaxes
2180 Changed YAZ so that it links with compiled ASN.1.
2182 Added Explain-schema definitions and mapping routines. The following
2183 Explain categories have been implemented: AttributeDetails,
2184 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2186 Fixed minor bug in Windows version of Server Library.
2188 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2190 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2192 Added EXTERNAL: UNIverse Resource Report (non-standard).
2194 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2195 ENUMERATED and SET OF.
2197 * Added 'const' to some of the char pointer arguments for the
2198 functions, data1_read_node, data1_getelementbytagname,
2199 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2202 Fixed bug in data1_insert_taggeddata - the last_child member of
2203 parent wasn't initialised.
2205 * Changed data1_read_record and data1_read_node so that the supplied
2206 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2207 doesn't refer to any parts of the "SGML"-buffer.
2209 Fixed bug in server library (Windows version of statserv_remove).
2211 * Changed code so that it compiles as C++. The type definition
2212 of Odr_fun which is a member of Odr_arm was changed. The result is,
2213 that an explicit typecast is needed for the fun pointer when
2214 using Odr_arm - as in:
2215 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2217 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2219 Implemented the new structured date and time definition as approved
2220 by the ZIG. Added schemaId element to the specificTag in Espec-1
2221 (also approved at the last ZIG). Thanks to RVDM.
2223 Added some Object identifiers (RVDM).
2225 Changed the Update Extended Service (RVDM).
2227 Added command "refid" to client which specifies referenceId for
2228 the following requests.
2230 Implemented extended service handling for server. See ztest.c
2231 for an example as well as backend.h. New handlers are registerd
2232 in the Init handler.
2234 * Changed interface for sort in server.
2236 Added new members to statserv_options_block. It allows a server
2237 to read options from another source than just the command line. Thanks
2238 to Charles Woodfield.
2240 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2241 renamed to zboolean. Some C++ compilers complained about the name.
2243 Minor changes to gils.abs. Added index 's' (sort) on title
2244 and date/time-last-modified.
2246 --- 1.4pl2 1998/1/30
2248 Fixed bug in server library regarding inetd mode (-i). This bug
2249 was introduced by release 1.4.
2251 --- 1.4pl1 1998/1/29
2253 Added sort facility in client and backend server interface.
2255 Fixed problem with dependencies in Makefile(s).
2257 Fixed bugs for encoders/decoders of extended services and
2260 Implemented sub-tree feature for schemas. Sub-trees are
2261 referenced in *.abs-files. See explain.abs for an example
2262 of the use of this feature.
2264 Modified bib1.att; local attributes for ANY didn't include
2265 ANY itself (only affects use of the retrieval module).
2267 Fixed bug in plain SGML reader in function data1_read_node:
2268 tags with prefix "var" was incorrectly interpreted as variants.
2270 Added feature "sub-schemas" to enable references to - and definitions
2271 of - group of elements.
2273 * Removed member parent from type data1_element (in data1.h).
2275 Implemented function odr_nullval() that returns the value of
2278 * Removed member num_children from data1_node (in data1.h).
2280 Made NT service interface part of the server library. The
2281 function statserv_main uses the NT service when required and
2282 calls the statserv_start / statserv_close routines.
2284 Routine zget_SearchRequest and zget_PresentRequest fills
2285 resultSetName/Id member with "default" instead of "Default".
2287 Fixed memory leak in server. Request queue member wasn't freed.
2289 Fixed nmem_exit so that memory is freed.
2293 Revised the CCL parser utility to be thread safe.
2295 Added function, oid_ent_to_oid, to replace the function
2296 oid_getoidbyent, which is not thread safe.
2298 * Added nmem_init and nmem_exit to initialize and release
2299 NMEM resources. Function nmem_init should be called once in the
2300 initial thread before NMEM/ODR is used. statserv.c and client.c
2301 have been changed accordingly. The change was necessary to make
2302 NMEM thread safe. The NMEM memory pool is shared amongst threads
2303 in a process. Unix-based applications will still work fine without
2306 Added NT Services interface for the the Z39.50 (statserv) Server.
2307 Refer to the ztest.c source on the usage.
2309 Windows 95/NT port using MSVC5.0. Project files are included in the
2312 * Defined new 'global' handle for the retrieval (data1) system. The
2313 new handled, data1_handle, describes the state of the data1 system.
2314 This handle is passed as first argument to virtually all
2315 data1 related routines. The functions data1_create and data1_destroy
2316 creates and destroys a data1 handle respectively.
2318 Added ODR encode stream member to all backend request structures
2319 init, search, scan etc. This stream should be used to allocate all
2320 memory used for the response when thread safe operation is needed.
2322 Changed the comstack utility, cs_addstr, to be thread safe. The
2323 returned hostname string returned by the function is now part the
2326 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2327 function. The cs_straddr takes a COMSTACK handle as argument, so this
2328 function must be used after cs_create and before bind/connect.
2329 This function is thread safe.
2331 Moved test server to 'ztest' directory - generic server code still
2332 in 'server' directory.
2334 Made prefix query (pquery.c) utility thread safe.
2336 Added new function modifier YAZ_EXPORT to 'export' public DLL
2337 functions when using windows (see include/yconfig.h).
2339 Added definitions to the OID database (util/oid.c) (RVDM).
2341 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2343 Added call to ccl_rpn_delete in client program.
2345 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2346 release of RPN structure.
2348 Added support for C++, headers uses extern "C" for public definitions.
2349 With input from RVDM.
2351 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2352 Thanks to Ronald van der Meer (RVDM).
2354 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2356 Added support for private extensions to the OID database
2357 (oid_setprivateoids()). Thanks to RVDM.
2359 Added optional, physical ANY (key replication)
2361 Fixed null-reference problem in GRS-1 output filter.
2363 Proximity operator added to Prefix Query Format (PQF).
2365 In test client command "base" accepts multiple databases.
2367 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2371 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2373 Smallish bug-fixes in the new encoders/decoders (explain).
2375 Bug fixed in DeleteRequest.
2377 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2379 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2381 Added SOIF syntax (using private OID for now) to retrieval module and client.
2383 Added Update extended service.
2385 Added SearchResult-1 additional info structure.
2387 Added optional CCL (ISO8777) interpreter as separate module. Available
2390 --- 1.2 1996/6/10 (1st anniversary release)
2392 Added Summary record syntax. Lightly tested.
2394 Added OPAC record syntax. Untested.
2396 Added ResourceReport service encoders/decoders. Untested.
2398 Fixed bug in z_Unit - wrong tagging on unitSystem.
2400 Fixed bug in the DiagRecs decoder.
2402 Added options for max PDU size and session timeout to frontend-server.
2404 Added documentation of query-language parsers and other supporting utilities.
2406 [frontend-server] Added Attribute set to the bend_scanrequest API.
2408 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2409 surrogate diagnostics were generated.
2411 [retrieval] Allow multiple local values for attribute.
2413 [retrieval] Allow multiple attributes per element in .abs files. index type.
2415 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2417 --- 1.1pl2 1996/4/10
2419 Minor changes, mostly specific to Zebra's requirements (retrieval)
2423 Repaired bug in frontend server when running multiple listening
2424 endpoints in dynamic mode.
2426 z_External() now won't break if a known, ASN.1 value comes encapsulated
2427 in an octet-string. The value will pass through unmodified in an Odr_oct.
2429 Added a bit of code to the demo client to decode & display
2430 ASN.1-structured records represented in the octet-aligned branch of
2431 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2433 Added z_ext_getentbyref() to the ASN module. Doc updated.
2435 * Completed the SCAN definition in the ASN module. This may break SCAN
2436 code based on older YAZ-versions at compile-time. The fix is easy -
2439 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2440 under the SCAN definition. Remember to initialize this, server-people.
2442 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2443 that this does not extend to ODR and ASN.
2445 Comstack allows insertion of established socket (primarily for
2446 inetd-operation of servers). Doc updated.
2448 Front-end server can now start from the inetd in TCP mode. Doc
2451 --- 1.0pl4 1996/1/24
2455 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2456 the rank and record number.
2458 Adjustments to the frontend server.
2460 Fixed diagnostic BER dumper. It ignored the file argument.
2464 Various changes to retrieval module.
2466 Changed the union discriminators of the protocol files from enums to
2467 ints paired with #defines.
2469 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2472 *Changed operator in the RPN structure to 'roperator', again to avoid a
2475 Fixed problems in Explain decoders/encoders.
2477 --- 1.0pl2 1995/12/6
2479 Memory bug in log module fixed.
2481 --- 1.0pl1 1995/12/5
2483 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2485 Bug in Explain DatabaseInfo module fixed.
2487 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2491 The shift to v1.0 signals that we now consider the *core* functionality
2492 of YAZ reasonably stable (the core being more or less equivalent to
2493 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2494 tested (Explain not at all - though that will happen soonish).
2496 Minor changes to code to support Windows port.
2498 Various minor changes after we're getting to use GRS-1 & co. more.
2500 Added Espec-1 format.
2502 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2503 of the protocol and it cannot be selected when encoding (maps into 'string'
2504 when decoding). Needed to talk to some servers.
2506 Demo client can request simple element set names.
2508 Added Diagnostic Format encoders/decoders.
2510 Added simple Close handling to frontend server (no hooks for resource
2511 reporting yet), and demonstration client.
2513 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2515 --- 1.0b3 1995/08/24
2517 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2518 handled incorrectly when records were requested in the searchResponse. This
2519 will only affect you if you use the frontend-server.
2521 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2522 Test-client will ask for and print GRS1. Ztest will return dummy records
2525 Added Explain encoders/decoders to the service-level API. Untested.
2527 Added Extended Services: Item Order encoders and decoders to the Service-
2528 level API. Untested. We could use a recent copy of the pertinent bits
2529 of the ILL protocol to add those bits.
2531 Added diagnostic format 1 encoders/decoders to the service-level API.
2534 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2535 odr_cons.c, which causes a more correct output.
2537 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2538 was always set to 0 when no records were requested in the searchRequest.
2540 * Added better external-handling. This shouldn't harm old code that
2541 *encodes* externals. It can break code that looks for a
2542 'single-ASN1-type' representation, since those types that are known
2543 are now decoded immediately. Look at the SUTRS sample code in
2544 seshigh.c and client.c. Documentation updated.
2546 Handling of structured records in bend_fetchresponse. Length -1 marks
2547 structured record, type is deduced from format field.
2549 --- 1.0b2 1995/06/27
2550 Fairly quick maintenance release to add SUTRS support.
2552 Fixed handling of SUTRS records in the demonstration client.
2554 * Added format field to the bend_fetchrequest and bend_fetchresponce
2555 structures of the backend API (frontend server). When the record is
2556 returned, the value of the format field is mapped to an OID. The
2557 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2558 of the record. The special value VAL_NONE in the bend_request means
2559 that no specific format was requested by the client. Documentation
2560 updated accordingly. Test server (ztest) will return a fixed dummy
2561 SUTRS record if your client requests SUTRS.
2563 Documentation updated accordingly.
2565 You can now set external libraries and RANLIB support in the top-level
2569 First public release.
