3 For configure, using option --without-xml2 also disables Libxslt/Libexslt
6 Fixed bug #2352: yaz-marcdump crashes for certain record.
8 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
10 Added support for Danmarc2 to UTF-8 conversion.
12 Added support for ISO5426 to UTF-8 conversion.
14 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
15 implementation version.
17 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
21 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
22 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
24 ZOOM C now interprets databaseName option for ZOOM connection as path
27 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
29 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
31 Dummy Libxml2 types no longer defined in headers of YAZ'.
33 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
38 Various ODR chapter fixes.
40 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
42 Added missing source for Windows compilation, mutex.c.
44 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
46 For SRU connections in ZOOM all records up to "count" are now fetched.
48 Fixed crash in generic frontend server (and yaz-ztest) which occurred
49 in Windows due to bad error handling for Libxml2.
51 Added facility for sending arbitrary records (ASN.1 any) using
52 ZOOM C's Extended service update. Patch by Sam Reynolds.
54 New options for ZOOM C's connection, logapdu which makes ZOOM log
59 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
63 Fixed memory violation that could occur when decoding UTF-8. This bug
64 was only present in 3.0.30 of YAZ.
68 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
69 GNU TLS is used by default (if found).
71 yaz-ztest returns OPAC records if a client asks for OPAC.
73 Improved speed of MARC-8 encoding.
75 Added support for lossy and loss-less MARC-8 encoding.
77 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
79 Added new Windows Service wrapper (sc).
81 yaz-client's itemorder command may now send a file.
83 Fixed yaz-marcdump to allow the use of NS prefix for record element.
85 Added new function yaz_log_xml_errors.
87 Allow (but warn) unknown XML attributes in MARCXML parsing.
89 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
91 The UTF-8 to MARC-8 conversion now uses a different set of characters
92 for Greek symbols. Bug #2120.
96 Added yaz_daemon (daemon.h).
98 Fixed bug #2068: pkg-config trouble
100 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
102 --- 3.0.24 2008/01/28
104 Document --with-xml2 option.
106 Added OPAC XML XSD (etc/opacxml.xsd).
108 Allow glob mask for name attribute in retrieval element for the
109 generic frontend server's retrieval facility.
111 Changed yaz_poll_poll to return yaz_poll_except for all returned events
112 except POLLIN/POLLOUT.
114 Fixed error handling in cs_listen. Bug #2037.
116 --- 3.0.22 2008/01/20
118 Fixed version in yaz/yaz-version.h.
120 Fixed bug #2027: Crash when closing connection.
122 Changed configure so that ICU support is only enabled if only ICU
123 and Libxml2 is available (because the ICU chain is XML based).
125 --- 3.0.20 2008/01/15
127 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
128 is built. Only this DLL depends on the ICU runtime.
130 yaz-ziffy is no longer part of YAZ. It is distributed separately by
131 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
133 Changed license of CCL module to 'Revised BSD'. After consultation with
134 remaining members of the original EUROPAGATE consortium, we are re-issuing
135 the CCL module without a separate license. The software was developed by
136 Index Data as part of a research project. The special license was included
137 to help feed usage information back to the project consortium to support
138 project evaluation. At this time, the project consortium has long-since
139 disbanded, and the majority of the original principals have retired. At the
140 same time, we have significantly modified the software during the following
141 years, to the point where very practically no original code remains. To
142 simplify re-use of the software, we have contacted those members of the
143 consortium who could be reached, and agreed to re-issue the module as a
144 proper part of the YAZ package.
146 Tcl scripts uses /usr/bin/tclsh as preferred shell.
148 CQL closer to being version 1.2 compliant. CQL also allows free-form
149 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
152 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
153 bug could make Extended services handling crash in the ZOOM layer. This
154 bug was only present in YAZ 3.0.18.
156 --- 3.0.18 2007/12/19
158 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
161 yaz-marcdump reads and writes collection wrapped records.
163 Handle OPAC for record conversion module.
165 Fixes for ICU wrapper.
167 Allow ICU libs to be controlled with --with-icu .
169 --- 3.0.16 2007/11/12
171 Added yaz_poll which is a wrapper for select/poll. When poll is available
172 and non-buggy, it is used, by yaz_poll . This allows more than 1024
173 sockets to be in use.
175 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
176 functionality through an XML based configuration (ICU chain). This system
177 is useful for search facilities such as Pazpar2 and Zebra that needs to
178 perform tokenization of indexed material. The ICU code in a separate
179 library libyaz3_icu.a.
181 Added HTTP tunnel facility for COMSTACK, bug #1752.
182 This is a facility that allows a Web proxy, such as squid, to tunnel
183 Z39.50 traffic. This facility is "transparent" to must applications
184 using YAZ. It's enabled by using pseudo transport connect: followed by
185 the proxy address, followed by command, then follwed by he regular
186 "virtual" addresss. For example,
187 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
189 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
191 --- 3.0.14 2007/09/21
193 Fixed bad memory reference in ZOOM_record - cuased by member not being
194 initialized. This was a problem only in YAZ 3.0.12.
196 Fixed bug in conversion from MARC to XML: Non-XML characters in control
197 fields were not removed.
199 Changed the way C code is generated from codetables.xml. Made a MARC-8
200 conversion trie for each characterSet section rather than codeTable.
201 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
202 of codetables.xml from Larry Dixson, LOC. Bug #1464.
204 --- 3.0.12 2007/09/12
206 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
207 from ZOOM_record_error).
209 ZOOM C function ZOOM_record_get returns record schema for type="schema".
211 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
213 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
215 Better SRW-to-Bib-1 diagnostic mapping.
217 ZOOM C and yaz-client announces SRU version 1.2 by default.
219 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
222 Fixed in yaz_sru_decode to allow other version than 1.1.
224 --- 3.0.10 2007/08/22
226 Added support for SRU scan for ZOOM.
228 Added support for the use of the older versions or Extended Service
229 Update in ZOOM. To faciliate this, an option "updateVersion" may be
230 set to the version , 1=first, 2=second, 3=third. The third version is
231 what ZOOM C has used so far. And that, obviously, is the default.
233 Added support for CCL queries in Z39.50 queries sent to the GFS (and
234 therefore in Zebra and in SimpleServer-based applications). The new
235 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
236 qualifier file used to transform incoming CCL queries into Type-1 RPN,
237 which is passed into the back-end search callback function.
239 Added support for HTTP Basic authentication in clients: the SRU/W
240 codec encodes the username/password elements of the PDU structure
241 appropriately, and these may be set using the "user" and "password"
242 options in ZOOM-C applications (the same options that are used for
243 Z39.50 authentication).
247 Fixed bug #1208: SSL appears to be broken in ZOOM.
249 Fixed bug #1206: Libxml2 include path weirdness.
251 Added oid_name_to_dotstring.
253 Allow elementSetName to be specified for ZOOM C record update.
255 Allow waitAction to be specified for ZOOM C based for Extended Services.
257 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
258 syntax OID. Bug introduced in YAZ 3 series.
260 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
264 Fixed bug #1157: yaz-client does not read .yazclientrc from current
265 directory. yaz-client now reads commands from file given by option -f
266 if specified; then tries to read .yazclientrc in current directory.
267 Failing that, it reads .yazclientrc from user's home directory.
269 Added support for correlationInfo Note and ID for Record Update via
272 Added yaz-client command querycharset which specifies character set for
273 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
274 (termListAndStartPoint).
276 Charset ISO5428:1984 is an alias for ISO5428-1984.
278 Implemented a way to perform scan in a result set using Z39.50. This
279 is achieved by attaching the result set name in the characterInfo
280 (type InternationalString) of OtherInformation in the Scan Request PDU.
281 The result set is identified in the otherinformation by the new OID:
282 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
283 This allows for scan in result set and faceted search . Zebra did some
284 of this in the APT term using attribute type 8 and value being result
285 set. Using the OtherInformation approach for this is cleaner and easier
286 to work with in proxies and the like. This facility can be used in
287 yaz-client using new command setscan which takes a result set as first
288 argument, start position (APT) as second.
290 Changed decoding of SRU XML packed records to deal with servers that
291 have recordData with XML data with multiple root nodes. Also make
292 comparison for recordPacking case insensitive. Again, one server
293 returns "XML" where others return "xml".
295 For SRU responses allow Content-Type application/xml as well as text/xml.
299 Fixed bug in character set conversion of BER strings. Bug introduced
304 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
306 For OID class, use oid_class consistently.
308 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
311 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
312 character set for bibliographic information interchange". By Giannis Kosmas.
314 Added documentation on new OID API.
318 Changes to generic frontend server interface: added new member
319 'query_charset' for bend_initrequest structure. A backend init handler
320 should set this member to its native character set for query terms.
321 When defined, the frontend server logic will announce this character set
322 to a client if the negotiationModel bit is set by the client. All server
323 implementors are encouraged to specify this. If a backend server does not
324 specify this a warning is issued using yaz_log(YLOG_WARN,..).
326 Added CCL utility to remove terms (stop words) from resulting RPN
327 tree. This is handled by functions with prefix ccl_stop_words_ .
329 New ZOOM C option, "rpnCharset", which allows client-side conversion of
330 terms in RPN queries.
332 Clean-up the CCL API. Moved some internal structures from ccl.h to
333 private header cclp.h. Changed ccl_parser_create so that a Bibset must
334 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
335 This is replaced by ccl_parser_find_str which takes a string instead.
337 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
338 libyaz.la is the core of YAZ except the generic frontend server and
339 does not depend on POSIX threads anymore. libyaz_server.la is the
340 generic frontend server facilities and uses POSIX thread functionality
341 if available. The libyaz.la no longer depends on POSIX threads because
342 the number of global structures is limited. NMEM no longer re-uses blocks
343 between threads ; it simply free's memory immediately but allocates in
344 "large" chunks as usual. We don't expect any performance penalties
345 because of this. The yaz_log system is still using a global log_level so
346 caution must be taken when modifying it with yaz_log_init_.. +
347 yaz_log_mask_str. This, however, should not cause any trouble because
348 these functions are called during initialization of application code
349 anyway. `yaz-config --libs server` returns libs for server applications;
350 `yaz-config --libs` returns libs for non-server applications.
352 New OID database - with public definitions in oid_db.h. Removed old OID
353 database including the head oid.h and definitions such as enum oid_value
354 and struct oident. The new OID database uses the same string names as
355 before but the 'protocol' is gone. There are now only two representations
356 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
357 converts from string to OID; functions with prefix yaz_oid_to_string
358 converts the other way.
360 Change to emit_term() in CQL-to-PQF query translation: when a term has
361 the /regexp relation modifier, do not process it for leading and
362 trailing "^" and "*", which have quite different meanings in regular
365 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
366 write handlers no longer carries a 'last' parameter. This will make
367 yaz_iconv flush "less" characters. A flush is performed by call to
368 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
370 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
371 removed, because function yaz_query_to_wrbuf does the same.
373 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
374 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
376 Deprecated MARC utility functions removed.
378 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
381 Branch split: YAZ_2_1_55_branch
383 --- 2.1.54 2007/03/16
385 Fix to ZOOM-C so that transparent reconnection is properly handled on
386 connections that are in asynchronous mode.
388 Fixed compilation on OpenBSD 4.0.
390 Large strings in GRS-1 records are now properly displayed in yaz-client.
392 Added character conversion support for "advancegreek"; based on patch from
395 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
396 sequence is met. Before the error was not set so it would be unknown.
398 Adjust yaz-marcdump MARC reader so that it skips until record separator
401 --- 2.1.52 2007/03/07
403 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
404 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
405 fd_set structure used as a bitmask for the FDs to be selected on.
407 Using ACX_PTHREAD macro to check for POSIX threads.
409 Fixed have-vsnprintf check.
411 --- 2.1.50 2007/02/23
413 Fixes for configure on BSD. Bug #900.
415 Added snprintf/vsnprintf wrappers for systems that don't have
416 limits (heavens forbid).
418 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
419 created before all previous tasks were completed and removed from the
420 task queue, the new task could be removed by a mistake.
422 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
424 Implemented pass-through CQL-to-PQF conversions. Bug #861.
426 Fixed bug #832: Problem with MARC/charset in yaz-client.
428 Fixed bug #668: save command line history for yaz-client.
430 Fixed bug #830: pkg-config support.
432 --- 2.1.48 2007/01/23
434 Extended ZOOM result set options with two options that may be read by
435 a client: resultSetStatus and presentStatus with values as specified for
437 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
439 Fixed bug #827: Using SSL fails on Debian etch.
441 Fixed bug #826: Weird looking chars for set of MARC records.
443 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
444 that is treated as an ItemOrder with itemRequest being an XML document
445 external. The value of "doc" is the content.
447 Extended the GFS search facility. New member of bend_search_rr
448 'estimated_hit_count' signals that hits is known to be an estmate
449 (higher or lower than real hit count). New member 'partial_resultset'
450 signals that the search was partial (hit count is lower or equal than
451 real hit count). For Z39.50, the information is stored in resultSetStatus
452 member of SearchResponse APDU. For SRU, the information is signalled
453 via SRU diagnostic 59: "Result set created with valid partial results
456 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
458 --- 2.1.46 2007/01/13
460 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
462 Added ZOOM_connection_peek_event.
464 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
465 the following new functions:
466 ZOOM_event_nonblock, ZOOM_connection_process,
467 ZOOM_connection_get_{socket,mask,timeout},
468 ZOOM_connection_fire_event_{timeout,socket}.
469 The existing blocking event handler, ZOOM_event, is a wrapper for the
470 + blocking ZOOM_event_sys_{poll,select}.
472 Implemented function ccl_xml_config which parses XML version of CCL
473 configuration (bug #798).
475 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
477 Added timings utility (yaz/timing.h)
479 --- 2.1.44 2007/01/03
481 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
484 Fixed bug #779: Rotation of apdu.log fails.
486 Fixed for character set conversions:
487 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
488 Honor G1 set in MARC-8 decoding.
490 --- 2.1.42 2006/12/17
492 Fixed bug #775: char conversion does not handle Alternative UTF-8
495 Implemented function yaz_marc_read_line which parses MARC line format
496 records. There is a wealth of formats out there. So far, this function
497 reads line records produced by yaz_marc_write_line.
499 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
500 more generic and easier to remember(!) options: -i format and -o format
501 which specifies input format and output format respectively - where
502 format is one of "marc", "marcxml", "line", "marcxchange".
504 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
505 does not print anything except warnings for records.
507 For yaz-marcdump, added support for MARC split into files (-s) with a given
510 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
511 spec, at http://www.loc.gov/standards/sru/record-update/
512 This has changed the binary layout of the following structs:
513 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
514 bend_update_rr . Patch by Ko van der Sloot.
516 Added GFS utility function bend_assoc_is_alive which returns 1 if
517 association is still alive (client is connected); 0 otherwise (client
518 closed connection). This allows busy servers to stop working for
521 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
522 been a separate piece of software. This version of ziffy has been modified
523 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
525 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
527 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
528 Client code may now interrogate options such as "init_opt_sort" to
529 find out whether the server claims to support various options.
531 --- 2.1.40 2006/11/27
533 Added utilities yaz_{set,get}_esn to set/get element set name from
536 Removed the build of libyazthread.la. The libyaz.so is the threaded version
537 of YAZ and has been so since YAZ 2.1.10.
539 Implemented ZOOM_record_error which returns error information for
540 record (surrogate diagnostic).
542 --- 2.1.38 2006/10/31
544 Updates for SRU Update by Ko van der Sloot:
545 1. Changed name from "operation" to "action"
546 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
547 versions in the code, marked as 'backward compatible'.
548 3. Added diagnostics for SRU Update.
550 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
552 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
554 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
556 For GFS, fixed problem with SRU diagnostic 'First record position out of
557 range' being issued for 0 hits.
559 zoomtst10 part of Windows Build.
561 --- 2.1.36 2006/10/13
563 Implemented yaz_filepath_comp which splits a path into file path
564 components (required by Zebra 2.0.3+).
566 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
567 BSD inspired license until now so this should not have any real impact on
568 anybody. See http://www.opensource.org/licenses/bsd-license.php
570 Fixed bug #687: Missing log lines.
572 Fixed bug #678: CQL to PQF translation does not preserve double-quote
575 Fixed bug #689: SRU diagnostics to be added.
577 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
578 whether a connection is idle (no more work do do).
580 --- 2.1.34 2006/10/04
582 Change type of optval from long to int for invocation of setsockopt with
583 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
585 Added support for specifying the max log file size for the Generic
586 Frontend Server. The size is given with option -r.
588 --- 2.1.32 2006/09/21
590 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
592 --- 2.1.30 2006/09/17
594 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
597 Fixed bug in Generic Frontend Server that could cause a server to stop
598 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
600 For the generic frontend server, the maximum record size is used as maximum
601 size of incoming packages (SRU + Z39.50). The value until was previously
602 only used in Z39.50 Init negotiation and, later, in a session controlled
603 sizes of records returned. This is controlled using -k option. It can be
604 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
606 --- 2.1.28 2006/09/04
608 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
611 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
613 New option for yaz-marcdump -lpos=value which allows setting a portion
614 of MARC header to a certain value.
616 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
618 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
619 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
621 --- 2.1.26 2006/08/15
623 Fixed problem with SRU mode type (soap, get, post) for yaz-client
626 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
628 --- 2.1.24 2006/08/08
630 Fixed MARC ISO2709 encoding routines to deal with character set
633 Minor changes to GFS logging. Database included in search request log
636 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
637 cached/multiple records.
639 Shared libraries are built by default on Unix+configure.
641 Changed cql2pqf transformation to use a different evaluation order. The
642 new order is: always, relation, structure, position, truncation, index
643 and relationModifier. Old order was: always, relation, relationModifier,
644 structure, index, position, truncation. Note that the the latter ones
645 override former ones for identical attributes.. The new scheme means that
646 it is possible to override any existing attribute with a relationModifier.
647 And also that it is possible to override everything for the index rule
648 (except the ones listed in relationModifier). No order is perfect but this
649 one, we believe, covers more real cases.. The "always" should have been
650 called "default", since the attributes there can be overridden with all
653 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
654 compilation phase, but also for yaz-config --cflags output. This allows
655 us to have public headers with Libxml2 stuff in them . It should also,
656 eventually, make Libxml2 checks redundant in packages using YAZ, such
659 --- 2.1.22 2006/06/15
661 Changed SRU update structure bend_update_rr so that SRU diagnostics are
662 stored in uri, message and details.. Previously diagnostics were stored
663 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
664 compatibility.. but he's probably the only one affected, so.
666 Added support for CCL, compiled on the client side, in ZOOM-C. This
667 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
668 input; the resulting query objects can be used for for searching with
669 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
671 YAZ' configure searches for OpenSSL by default.
673 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
674 SL_CTX_use_certificate_file. See
675 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
676 for more info. Thanks to Ko van der Sloot.
678 --- 2.1.20 2006/06/02
680 Bug #600: SRU GET, POST support for yaz-client. Introduced
681 command 'sru' which selects method SOAP/GET/POST.
683 Allow missingValueAction to be specified for the sortspec string -
684 function yaz_sort_spec. By default, the missing value action is null.
685 Use ! to specify "abort". Use = followed by stringvalue to specify default
688 Ensured that Present-handler (if defined) is called in GFS before any call to
689 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
690 searchRetrieve requests.
692 Documentation for YAZ is now based on the Docbook XML/XSLT using
693 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
694 is no longer depending on jade/openjade or docbook-to-man scripts.
695 PDF is no longer part of the distribution - but can optionally be
696 made using DSSSL/jadetex or FOP.
698 Added retrieval handling support in Generic Frontend Server to support
699 conversion between MARC/XML as well as XSLTtransforms. See
700 etc/yazgfs.xml for an example.
702 Added Authentication support to Generic Frontend Server in SRU
703 mode. Authentication using HTTP Basic is supported, as is the use
704 of 'x-username' and 'x-password' parameters in the request itself.
706 Added support for a new character set MARC8s identical to MARC8 except
707 that it converts combined characters to single Unicode characters in the
708 Latin-1 range (when possible).
710 --- 2.1.18 2006/04/24
712 ASN.1 compiler 0.4: generates brief Doxygen file header for
713 generated .h/.c files.
715 Utility yaz_iconv now supports conversion to MARC-8.
717 New facilities for the MARC module. The reading - and writing of
718 content are separate methods for the yaz_marc_t handle. The following
719 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
720 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
721 format). Write functions have prefix yaz_marc_write_.. The existing
722 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
723 available. Removed support for OAI-MARC and simplexml (not the
724 simplexml from PHP5).
726 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
727 to be returned for this connection.
729 --- 2.1.16 2006/03/31
731 Allow multiple languages and charsets to be specified with
732 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
733 negcharset iso-8859-1,utf-8
735 Translation of proximity nodes from CQL into PQF now works.
737 Moved to automake 1.8, 1.9.
739 Added function yaz_log_set_handler which allows a log handler to be
740 installed. This handler will be called for all log messages. Output
741 to file is also produced; but that can be disabled by passing NULL
742 fname to yaz_log_init_file.
744 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
746 For SRW (including GFS), accept application/soap+xml as content-type
749 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
750 produces NO stylesheet reference even if a default stylesheet is specified
753 --- 2.1.14 2006/03/14
755 Updated Windows package to include yazd.dll + yazd.lib for the
756 Development component.
758 If the environment variable YAZ_LOG is set, then it is used as a
759 string indicating the default level of logging to use if not
760 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
761 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
762 used as before. So, for example, to omit warnings from YAZ logging,
765 cql_transform() now map structure and other attributes before indexes,
766 so that index-specific structures and other attributes can override
767 defaults. So now a combination of mapping specifications such as:
769 index.dc.date = 1=date-modified 4=5
770 does the right thing.
772 cql_transform() now also respects the "always" mapping specification,
773 which establishes an initial set of attributes to be used for all
774 terms except where overridden by more specific attributes associated
775 with the index, relation or modifier.
777 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
778 which mode to use; one of "post", "get" or "soap" (SRW, default).
780 Fixes for yaz_iconv routines: changed trie-based character set conversions
781 to use only non-negative values for bit fields due to Sun's C compiler not
782 supporting negative values.
784 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
785 sequences where not read correctly. Fix by Rustam Usmanov.
787 Updated win/makefile to use options, settings which makes things
788 compile with VS C 2005.
790 --- 2.1.12 2006/02/01
792 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
794 In ZOOM socket code, use select instead of poll on MacOSX.
796 ZOOM-C now support client-side compilation of CQL into RPN that is
797 sent to the server, enabling CQL to be used against all Z39.50
798 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
799 ZOOM_query object, and submit it using ZOOM_connection_search().
800 The CQL-to-RPN translation uses a configuration file, the name of
801 which must be specified in the Connection's "cqlfile" option.
803 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
804 function, which takes as its start-term parameter a ZOOM_query object
805 (which may have had either CQL or RPN set into it).
808 --- 2.1.10 2005/11/29
810 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
811 GFS to support this as well. Backend handler, bend_srw_update, does the
812 update work. Code contributed by Ko van der Sloot.
814 Allow retrieval of Search Result-1 information in ZOOM by the use of
815 options that are attached to a result set. ZOOM documentation updated
818 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
819 UTF-8 conversion. Patch by Raj Patel.
821 Added option -m to GFS to control formatting of timestamps in log file.
823 Added 'exit' as synonym for 'quit' in yaz-client
825 Added support for specifying SRW resultSetId + resultSetIdleTime in a
826 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
827 for the new members. Patch by Ko van der Sloot.
829 Added support for SRU POST. It is supported for content-type
830 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
832 Do not build the separate Multi-threaded (MT) library libyazthread.la.
833 Instead make the library libyaz.la multi-threaded. Threading as a whole
834 can still be disabled by configure option --disable-threads. Previosly,
835 with older GLIBCs there were problems with MT libs under Apache. This
836 has now been fixed a long time ago.
838 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
841 CQL module modified to be case insensitive for relations/indexes/operations.
843 Fixed bug in CQL transform code: incorrect value relationModifieder
846 Added 'show all' command for yaz-client which retrieves all results
849 Added new yaz-client, xmles, which takes a (private) OID and
850 a document to be sent as an extended service request.
852 Describe new yaz-client commands wait_response and set_auto_wait.
854 Increase TCP/IP listener backlog from 3 (which I am guessing was
855 copied from the SunOS manual entry way back when) so SOMAXCONN, so
856 that the socket will queue as many incoming connections as it's able
857 to handle ongoing connections. In other words, it will never now
858 refuse a connection that it would be able to handle merely because
859 it's not got around to accepting() enough of the pending connections
860 yet. This is the behaviour anyway under Linux, where the listen()
861 argument is ignored; but not under BSD and on systems such as
862 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
863 YAZ-based servers should now be uniform across operating systems in
866 yaz-marcdump uses 64-bit file access on some systems. This is enabled
867 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
868 This allows yaz-marcdump to read large MARC batches (>2 GB).
870 Modified all YAZ source files - except the source which is auto-generated
871 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
874 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
875 corresponding to the existing *_setl() function. These allow option
876 values containing arbitrary valuues.
878 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
879 ZOOM_resultset_sort() in new applications. Its behaviour is identical
880 except that it returns an indicator of whether or not the sort
881 criterion was accepted (0 for OK, -1 for invalid).
885 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
886 MARC output rather than returning "new" buffer.
888 yaz-client warns about unknown init options.
890 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
894 Added support for SRW sort in Generic Frontend Server. Patch
895 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
896 sortKeys - or NULL if none is provided.
898 Fixed bug #307: It was impossible to specify indefinite/no timeout
899 for ZOOM_event. Special timeout value -1 now means indefinite timeout
902 Added support for multiple languages and charsets to be specified in
903 ZOOM. Each charset/language is separated by a blank. If negotiation is
904 in effect in init-response, Option
905 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
906 Code based on patch by Vasiliy Osadchuk.
908 Fixed bug #306: infinite recursion that occurred when calling
909 yaz_log_level_init as the first call (before other log level or
912 Fixed bug in scan handling in front end server: if preferred-Position-In-
913 Response was non-present, a NULL pointer referece was performed.
917 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
918 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
919 now defined for all those error codes. So instead of putting 109 in
920 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
921 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
923 Modified the yaz-marcdump utility to skip garbage bytes between MARC
926 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
928 Program yaz-client now exits and produces an error message if multiple
929 Z39.50 servers are specified on the command line (none or one allowed
932 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
937 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
939 Fixed bug #272: Preserve spacing for CCL terms.
943 Added support for virtual hosts and multiple backend servers for
944 the YAZ frontend server. The configution is XML based and
945 support specificition of CQL to RPN mappings and explain information.
946 See section "Virtual Hosts" in the YAZ manual.
948 Extended OPAC display utility. OPAC display utility renders
949 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
950 to supplement yaz_marc_decode_wrbuf.
952 Fixed a bug in MARC decoder that could caused it to crash for some
953 invalid MARC records. More diagnostics and warnings where added in
954 XML output (warnings, etc are stored in comments).
956 --- 2.0.34 2005/02/08
958 Fixes for UNIX domain sockets. Bug #261.
960 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
962 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
963 Added yaz_marc_subfield_str which defines subfield lead string which is
964 used in YAZ_MARC_LINE format. Default string is blank+$. Added
965 yaz_marc_endline_str which defines end of fields string used in
966 YAZ_MARC_LINE format. Default string is newline.
968 Experimental support for MarcXChange. This format can be produced
969 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
970 http://www.bs.dk/standards/MarcXchange.xsd
972 Added yaz-client commands scansize that sets maximum number of
973 entries to be returned by scan.
975 --- 2.0.32 2005/01/11
977 Added support for SRW scan in yaz-client and Generic Frontend Server.
979 * Added whereInList member to SRW Scan Term.
981 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
983 Fixed NMEM system to return aligned blocks on the smallest boundaries
984 that are suitably aligned for all possible types on the particular
985 architecture YAZ is being built for.
987 --- 2.0.30 2005/01/04
989 Fixed numerious warnings that was issued with newer versions of GCC.
991 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
992 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
995 Make YAZ Generic Frontend Server slightly faster.
997 Enhance (and reduce) logging for Generic Frontend Server.
999 Revert YAZ log system so that it flushes every write operation
1000 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1002 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1003 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1004 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1005 will effectively disable old definitions.
1007 --- 2.0.28 2004/11/09
1009 Added yaz_log_time_format which specifies log format using
1012 Added yaz_log_module_level which returns mask for a module. Value
1013 is non-zero mask a if module is enabled; zero if disabled.
1015 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1016 in include/yaz/cql.h.
1018 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1020 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1022 Fixed bug #172: RPM builds does not enable SSL.
1024 Doxyfile.in part of dist. Doxyfile generated by configure.
1026 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1027 are given and the corresponding component does not exist.
1029 Extend CCL documentation in YAZ reference. Describe r=r.
1031 --- 2.0.26 2004/10/01
1033 Fixed MARC->MARCXML conversion to properly deal with
1034 fields, subfields, indicators having non-ASCII characters.
1036 Fixed MARC->MARCXML conversion so that ASCII control characters
1037 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1040 Added YAZ GFS support for conversion from Z39.50 surrogate
1041 diagnostics to SRW surrogate diagnostics.
1043 Bug fix: YAZ GFS did not return schema in explainResponse.
1045 --- 2.0.25 2004/09/30
1047 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1048 now converts recordSchema to elementSetName as well as schema URI.
1050 Fixed bug in COMSTACK that prevented HTTP request packages from being
1053 --- 2.0.24 2004/09/29
1055 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1056 does not require white-space before and after the dash in a range, e.g.
1057 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1060 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1061 due to new GCC removing "redundant" code.
1063 Added yaz-client commands scanpos and scanstep that sets preferred
1064 position and step-size for scan.
1066 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1068 Added CCL utility ccl_qual_buf which parses one or more CCL
1069 spec lines in a buffer.
1071 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1072 of name and value - ignoring empty lines and comments.
1074 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1076 Added odr_get_element_path which returns current element path for an
1077 ODR handle. This utility is useful in error handling or user-defined
1080 Added ODR_PRINT utility odr_set_stream which is is a more generic
1081 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1082 to a write function and pointer to close function. The close function - if
1083 non-NULL - will be called during odr_destroy.
1085 Fixed bug in CCL parser where truncation char was not removed from
1086 right side when truncation=both was in effect.
1088 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1091 --- 2.0.23 2004/08/11
1093 Fix buffer overrun in CQL parser when dealing with proximity (%).
1095 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1096 to UTF-8/UCS conversion is now only based on codetables.xml.
1098 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1100 --- 2.0.22 2004/08/06
1102 Add support for more "commit changes" in ZOOM (uses Extended Services).
1104 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1107 Yet another small fix for configure of SSL.
1109 --- 2.0.21 2004/05/14
1111 Fix SSL libs for configure when --with-openssl=DIR is given.
1113 --- 2.0.20 2004/05/10
1115 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1117 SSL comstack now uses yaz.pem certificate file on server side
1118 by default. Certificate filename can be configured by calling
1119 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1121 Fix bug regarding multiple calls to ZOOM_connection_connect.
1123 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1125 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1126 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1128 ZOOM now allows inspection of X509 peer certificate for verification.
1129 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1131 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1132 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1133 as "modular" but it simplifies things.
1135 Added cs_get_peer_certificate to that returns peer X509 PEM.
1137 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1138 NULL if SSL is unavailable.
1140 Documentation about MARC decoding tools.
1142 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1144 --- 2.0.19 2004/03/30
1146 Rename CHANGELOG to NEWS to follow GNU style packing.
1148 Fix bug with missing initialization of member in init_diagnostics.
1149 This bug affects threaded version of GFS server.
1151 --- 2.0.18 2004/03/20
1153 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1156 Ensure zlib.dll is packed with Windows install.
1158 --- 2.0.17 2004/03/17
1160 Fix encoding of xsd:string to use text instead of CDATA.
1162 Fix endless loop in CQL parser with unbalanced ".
1164 Use a more compact way to store MARC-8 conversion tables.
1166 --- 2.0.16 2004/03/16 Debian only
1168 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1171 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1176 --- 2.0.15 2004/03/01
1178 Another fix for decoding of XML packed records.
1180 --- 2.0.14 2004/02/25
1182 Fixes for Chunked encoding. White space not ignored after length spec.
1184 Update NS and use default NS for SRW diagnostic elements.
1186 --- 2.0.13 2004/02/23
1188 Implement ZOOM_resultset_cache_reset which resets record cache.
1190 Implement ZOOM_resultset_sort which sorts a result set.
1192 Implement chunked HTTP transfer.
1194 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1196 --- 2.0.12 2004/02/16
1198 Added member 'schema' to bend_explain_rr structure so that backend
1199 can specify explain record identifier. Defaults to Zeerex 2.0.
1201 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1203 --- 2.0.11 2004/02/16
1205 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1208 Added init command for yaz-client which sends "extra" init request.
1210 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1211 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1213 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1215 Make ZOOM error code for "invalid query".
1217 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1219 --- 2.0.10 2004/02/05
1221 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1224 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1226 Added option -p <file> to make Generic Frontend Server to write PID file.
1228 Added option -D to put Generic Frontend Server in background on its own.
1230 Make ZOOM C recognize option "password". If unset, "pass" is used
1231 (for backwards compatibility).
1233 Fixed a bug in Generic Frontend Server that could make it crash if a
1234 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1237 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1238 Must be issued before open, in order to be in effect.
1240 --- 2.0.9-6 2004/01/12 Debian/Windows
1242 Make the SRU server more picky WRT unknown params, etc.
1244 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1246 New YAZ client command, options, that sets Z39.50 options.
1248 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1249 options from a string of tokens (one token for each option bit).
1251 Update SRW diagnostic code messages.
1253 --- 2.0.9-5 2004/01/07 Debian/Windows
1255 Handle user defined stylesheet for SRW/SRU.
1257 --- 2.0.9-4 2004/01/06 Debian/Windows
1259 Fix bug in decoding of Content-Length.
1261 --- 2.0.9-3 2004/01/06 Debian/Windows
1263 Fix a bug with decoding of XML packed records.
1265 --- 2.0.9-2 2004/01/05 Debian only
1267 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1269 Fix bug in SRW/SRU diagnostics decoding.
1271 --- 2.0.9 2004/01/05
1273 Fixed bug in Generic Frontend Server which could drop records exceeding
1274 preferred message size. Reported and fixed by Irina Dijour.
1276 Fixed calculation of package size for structured records in Generic
1277 Frontend Server. Reported and fixed by Irina Dijour.
1279 Fixed namespace for SRW/SRU diagnostics.
1281 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1283 --- 2.0.8 2003/12/22
1285 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1286 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1289 CQL changes to reflect recent changes to the specification:
1290 * Documentation talks about context sets instead of index sets.
1291 * Documentation talks about indexes instead of qualifiers.
1292 * The CQL-to-PQF transformer's configuration file now uses
1293 "index.set.name = <attributes>" instead of the old form
1294 "qualifier.set.name = <attributes>". (Both forms are still
1295 understood but the latter is deprecated.)
1296 * CQL terms with no explicit index specified are now interpreted as
1297 cql.serverChoice instead of srw.serverChoice (which of course
1298 behaves exactly the same.)
1300 --- 2.0.7 2003/12/16
1302 MARC conversion can now generate ISO2709 output in another
1303 character set. yaz-marcdump uses this facility if you invoke it
1306 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1307 functions from there can be used from C++.
1309 --- 2.0.6 2003/12/04
1311 Frontend server now transfers memory from decoded packages to stream
1314 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1315 references to show up.
1317 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1318 the ZOOM Abstract API. The older names for the same options are still
1319 also supported for the benefit of old applications.
1321 ZOOM-C supports "implementationId" and "implementationVersion" options
1322 to go along with "implementationName". These allow the user code to
1323 specify identification strings to be sent to servers.
1324 Add OID for the new ExtLite attribute set.
1326 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1327 as requested/supplid by Ere Maijala <ere@atp.fi>
1329 For generic frontend server, reverse the order of
1330 "toolkit-supplied / application-supplied" strings sent as implementationId,
1331 Name and Version. Also, remove the spaces around the slash. This brings
1332 the GFS in line with the behaviour of ZOOM-C on the client side.
1334 Add function ZOOM_scanset_display_term.
1336 yaz-client shows scan displayTerm if present.
1338 Utility yaz-iconv is now installed by default along with the man page
1341 Extend configure check for OpenSSL to use pkg-config where available (such
1344 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1345 server to specify uid/gid/mask for socket using the format
1346 unix:[user=uid,][group=gid,][umask=mask,]file=path
1347 If file= is omitted the existing format is assumed, e.g.
1349 in which case the mask is 0666 (rw for everybody).
1351 Major restructure of YAZ source. All source in libyaz is in src directory.
1352 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1353 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1355 Added man page for utility yaz-marcdump (used to be called marcdump).
1356 yaz-marcdump is installed by 'make install'.
1358 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1359 of incoming package failed.
1361 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1363 Change prototype of odr_perror: add const to message string.
1365 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1367 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1368 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1369 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1370 DNS lookup. There should not be any compatibility problems with this
1371 assuming that blocking=1 or 0 is used.
1373 Fix bad reference in UNIX comstack in function cs_addrstr.
1375 Fix for compilation on AIX.
1377 The generic front-end server (server/seshigh.c) now supports returning
1378 Init diagnostics to the client in User-information-field, in
1379 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1382 --- 2.0.4 2003/09/04
1384 Allow any CQL relation (not just all,any,exact,scr).
1386 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1387 that features the same UI.
1389 Implemented command update0 in YAZ client which is equivalent to
1390 update but uses old of Ext Update ASN.1.
1392 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1393 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1394 Previously no OID was used for this info.
1396 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1397 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1398 returns 'malformed search term' otherwise.
1400 SortResponse member resultCount now set to NULL in sort handler of
1403 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1406 Add three new utility functions for translating OIDs between various
1407 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1408 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1409 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1410 char *oid_to_dotstring(const int *oid, char *oidbuf);
1411 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1413 Reverted modifications for ES Update definition for z_IU0Update
1414 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1415 is back to YAZ 2.0.2.
1417 String value attributes for CCL parser.
1419 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1420 which their FirstSearch server returns in Init responses, sometimes
1421 carrying useful diagnostic information when Init fails. This has the
1422 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1423 "z39.50/oclcui.asn", where its definition is somewhat different from
1424 what OCLC document on their web-site, as required to interoperate with
1427 Support for anonymous authentication in yaz-client. Use the command
1430 * Fix the OID of the Index Data-local "admin" Extended Service from
1431 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1432 the 1000, which indicates a locally-defined OID, was a mistake.
1434 --- 2.0.3 2003/06/20
1436 Fix CCL directive @case handling so that it affects string match for
1437 both CCL keywords and qualifiers.
1439 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1440 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1441 Decoder has been updated with ASN.1 changes as listed in
1442 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1443 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1444 z_IUUpdate, remains unchanged.
1446 ZOOM_record_get may now return a record in a specific character set.
1447 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1448 "from" is the character set of record as returned by target. "to" is
1449 the character set to be returned. If omitted, "to" is UTF-8.
1451 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1453 New ODR utility, odr_getelement, which returns name of element for
1454 which encoding/decoding failed.
1456 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1457 in cases where a required element was omitted.
1459 Bug fix: some MARC8 sequences were not converted.
1461 New ZOOM option "step" which specifies number of records to be
1462 retrieved in one chunk. Used in conjunction with "start" and "count".
1464 SRW support for yaz-client. Use scheme http: to use it, e.g.
1467 yaz-client no longer does (un)intelligent character set conversions
1468 by default. Can be enabled with charset and marc_charset commands.
1470 xmalloc trace fix for 64-bit systems such as DEC alpha.
1472 Solaris 2.6 compile fix.
1474 New function, cql_strerror() translates SRW error codes, as returned
1475 by cql_transform_error(), into human-readable English strings. Used
1476 in yaz-client diagnostics when appropriate.
1478 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1479 converts it into a type-1 query which is sent to the server. This
1480 makes CQL available for use with all Z-servers, as opposed to the tiny
1481 minority that can handle CQL queries themselves.
1483 --- 2.0.2 2003/04/28
1485 New Debian package layout similar to the Redhat Package layout.
1487 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1488 and search result respectively.
1490 --- 2.0.1 2003/04/25
1492 Redhat package is now several packages: libyaz (runtime libraries),
1493 libyaz-devel (development and documentation, and yaz (utility programs).
1494 Package spec file by Morten Bogeskov.
1496 New member 'schema' in struct bend_fetch_rr which the name of requested
1497 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1498 handler MAY set this to reflect the schema of the returned record.
1500 New member 'display_term' in struct scan_entry. GFS now sets member entries
1501 and allocates scan entries to be filled by user scan handler. In previous
1502 version, entries member was allocated by the scan handler. That still works,
1503 but the GFS will ignore member display_term - assuming it was NOT set by
1504 the handler. The fact that the GFS now allocates the entries both allows
1505 for new members and makes a scan handler easier to write.
1507 Fix CQL lex buffer overflow.
1509 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1510 SRU default recordPacking is string.
1512 SRU protocol support for frontend server.
1514 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1516 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1518 Added scan for the ZOOM shell (zoomsh).
1522 * String Identifers for Schemas (Amendment 5).
1523 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1524 Old definition for schema
1525 Odr_oid *schema; /* OPT */
1530 Z_InternationalString *uri;
1531 #define Z_Schema_oid 1
1532 #define Z_Schema_uri 2
1535 * resultCount parameter to Sort Response (Amendment 1).
1536 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1538 Support for SRW 1.0 over HTTP. This is an optional feature and
1539 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1542 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1543 on the same port. SRW SearchRetrieveRequests are mapped
1544 to bend_init,bend_search,bend_fetch,bend_close.
1546 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1548 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1549 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1551 ZOOM connections are SRW based if schem http is used for hostname
1552 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1553 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1555 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1556 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1557 distance=n, order=true/false, relation=le, prox unit=word. If
1558 n is omitted, distance 1 is used.
1560 Fixed problem with C compiler include path in wrong order.
1562 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1563 on Solaris. Patch from Ko van der Sloot.
1565 New MARC decode API. All new functions operate on a yaz_marc_t
1566 handle. The most important new functions are: yaz_marc_create,
1567 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1568 decode and destroy respectively. Decoder can produce formats
1569 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1570 include/yaz/marcdisp.h.
1572 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1573 to UTF-8, UCS-32, wchar_t or Latin-1.
1575 * Prototypes for yaz_iconv_-functions moved to separate header
1576 include/yaz/yaz-iconv.h.
1578 Make a few private functions 'static' in unix.c. This prevents
1579 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1581 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1582 are set when Init Response is received.
1584 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1585 but returns diagnostic set as well.
1587 New function yaz_strerror which is a portable wrapper for
1588 strerror/strerror_r/GetLastMessage.
1590 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1591 is returned for MARC. If type is "oai", then OAI MARC is returned.
1593 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1596 --- 1.9.2 2002/11/26
1598 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1600 Fix bad race conditions on SIGTERM and terminate gracefully in
1603 Move retrieval (data1) module to Zebra since nobody seems to be
1606 Add GRS-1 render for ZOOM using same format as yaz-client.
1608 --- 1.9.1 2002/10/05
1610 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1612 Fix broken ESpec handling in data1 module.
1614 SGML reader parses comments and makes them part of the data1 tree.
1616 Added several type casts so that YAZ compiles as C++ code.
1618 ZOOM didn't handle PDU encoding failures properly.
1620 Added more Bib-1 diagnostics (approved extensions).
1622 GNU configure: better check for iconv.
1624 More portable use of accept, getpeername. Check for socklen_t. Use
1625 int/size_t if socklen_t is not defined.
1629 PQF parser rejects bad queries - including those with extra
1630 characters in them. PQF parser used to silently ignore that.
1631 Cleaner API for PQF added, which allows you to get detailed
1632 error information for bad queries (see yaz/pquery.h).
1634 Fixed bug in ZOOM_record_get for type "database".
1636 Implemented mini iconv library supporting conversions between
1637 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1639 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1641 --- 1.8.9 2002/08/20
1643 Fixed ZOOM C record cache so that preferredRecordSyntax and
1644 elementSetName is used to check for already fetched records.
1646 --- 1.8.8 2002/08/02
1648 Added three members in bend_initrequest structure to facilitate
1649 character set negotiation.
1651 Fixed a bug in frontend server that could cause indefinite
1652 loops under rare conditions.
1654 Revised character set utilities (charneg.h) so that encoding
1655 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1657 For PQF, directive @term <type> sets term type for Scan/Search.
1658 Here <type> is general, string, numeric, null. The term type
1659 is inherited - just like @attr.
1661 New call odr_set_charset that sets character set conversion for
1662 international-strings on a ODR stream. Prototype is:
1663 int odr_set_charset(ODR o, const char *to, const char *from);
1664 The InternationalString is still represented as C string in YAZ
1665 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1666 won't). On the protocol level, you can use any encoding.
1668 Support for UNIX sockets in ZOOM.
1670 Solaris recv sometimes returns errno == ENOENT. It is treated as
1671 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1673 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1674 both client and server. Code by Morten Bogeskov.
1676 --- 1.8.7 2002/05/22
1678 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1679 that they can be used directly from Visual Basic. You must recompile
1680 your windows APP if you're using ZOOM.
1682 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1683 Commands "lang" and "charset" sets language and character set respectively.
1684 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1685 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1687 Attributes from multiple CCL fields may be OR'ed rather than merged
1688 using directive "@field or". Fields are still merged by default -
1689 equivalent to "@field merge".
1691 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1694 Fixed bug in zget for parameter ExtendedServicesResponse.
1698 --- 1.8.6 2002/03/25
1700 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1702 Client displays USR.1:SearchResult-1 (hits per term).
1704 Additional Search Info for search in Generic Frontend Server.
1706 Fixed CCL parsing of "field=s".
1708 WIN32 installer - using the excellent NSIS software from nullsoft.
1710 Fixed CCL parsing of "field = - <number>".
1712 Added function yaz_marc_decode that decodes MARC for line mode
1713 display or XML (similar to that used by JZKit).
1715 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1716 Z39.50. But ISO/ILL was, however.
1718 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1719 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1721 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1722 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1724 --- 1.8.5 2002/02/03
1726 New YAZ client features: Command completion and new commands:
1727 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1728 Code provided by Jacob Poulsen.
1730 New call oid_trav, that visits all registered OIDs via callback.
1732 Function ZOOM_record_get now returns const char pointer rather than
1733 void pointer. It saves a lot of type casts.
1735 For YAZ client, command "auth" now allows you to set authentication
1736 in IdPass style. It is enabled when three tokens are given - order
1737 is user, group and password.
1739 Fix memory leaks in MARC record handling for ZOOM.
1741 New option for YAZ client, -k <kilobytes> that sets
1742 maximum record size. Similar to -k option for generic frontend
1743 server and yaz-ztest.
1745 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1747 Prefix query parser reports "fail" when bad attribute set is given.
1749 Fix in MARC decoder. Proximity logging. Fix for attribute set
1750 in scan handler for server. Patches by Shigeru Ishida.
1752 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1755 Configure option --with-openssl=<dir> now works when a directory is
1756 specified. Patch provided by Morten Bogeskov.
1758 New option for YAZ client, -u <auth>, that sets authentication.
1760 ZOOM fix: error information was sometimes "missing", since error
1761 was cleared/reset too when it shouldn't.
1763 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1765 --- 1.8.4 2002/01/04
1767 Scan for ZOOM API. New object ZOOM_scanset. New functions
1768 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1769 ZOOM_scanset_destroy.
1771 New ZOOM function, ZOOM_connection_last_event, that returns type
1772 of last event (such as "receive data", "send data", "apdu received",
1775 New ZOOM option, schema, that specifies schema for retrieval.
1777 New CCL feature. Qualifiers can be aliases for one or more
1778 other qualifiers (if more than one is given, OR is used).
1780 ZOOM uses named result sets if target supports it.
1782 Two new YAZ client commands: . (dot, which sources a script of YAZ
1783 client commands), and ! (to execute shell command.). Implemented
1786 Working on Debian packages.
1788 --- 1.8.3 2001/11/19
1790 YAZ client enables named result sets only if target supports it.
1792 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1794 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1795 with key="host" to get same result.
1797 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1798 Function Z3950_resultset_record(s) returns references to records
1799 "owned" by resultset. To become owner use Z3950_record_clone.
1801 Function z_ext_record handles Extended Services. Thanks to
1804 --- 1.8.2 2001/11/12
1806 CCL Parser fix: ignore token comma when dealing with and-lists.
1808 Documentation updates for COMSTACK.
1810 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1811 Changed prototype Z3950_records. For some functions, int parameters
1812 were changed to size_t.
1814 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1817 New MARC decode/display function, marc_display_exl, which properly rejects
1818 non-ISO2709 records. YAZ client uses it.
1820 --- 1.8.1 2001/10/29
1822 Fix bug: local attribute set wasn't set correctly in PQF strings.
1826 * Old Z39.50 codecs no longer supported.
1828 Added ZOOM C binding. See http://zoom.z3950.org/
1830 Renamed states for COMSTACKs to avoid confusion with events.
1832 Implemented cs_look and proper cs_rcvconnect.
1834 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1836 Configure detects POSIX threads on OpenBSD.
1838 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1839 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1841 When error is returned from present handler, non-surrogate diagnostic
1842 is returned in present response (and fetch handler is no longer called).
1844 * Minor adjustments to pquery parser (PQF). Token characters may be
1845 escaped by using backslash (C-style).
1847 PQF parser allows string attribute values to be specified. For @attr,
1848 non-numeric characters after the equal-sign are treated as strings
1849 (e.g. @attr 9=title).
1851 CCL trunction character may be defined (@truncation in file)
1853 * function zget_ExtendedServicesRequest sets waitAction to
1854 waitIfPossible (was wait).
1856 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1859 CCL operator names may be set in field definition files (CCL_bibset).
1860 See ccl/bib1 for an example.
1862 Fixes in ASN.1 compiler for C++ compatibility.
1864 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1865 and "op_or" to avoid conflict with C++.
1867 Fixed problem with GNU readline detection on Redhat 7.0.
1869 Added step-size for Scan backend handler.
1871 Fixed bug that made the frontend server crash when no attribute
1872 set was specified for scan.
1874 Front-end server automatically switches to original working directory
1875 when installed as an NT service. Previously -w had to be specified to
1878 Added extended attributes for retrieval module (data1), so that data1
1879 records carry d1_readXML/SGML attributes. d1_read also supports
1880 null-data rules ( <tag/>)
1882 On UNIX when POSIX threads are available, a separate library libyazthread
1883 is created. Programmers should link with that library and the yaz library
1884 when using threads. The reason for the split was that some applications
1885 on Linux, such as Apache, doesn't work well when using shared objects that
1888 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1889 (or any frontend server) in SSL mode by specifying ssl: followed by
1890 address. Only tested on UNIX.
1892 Added feature for CCL module. Virtual structure s=al or s=ol generates
1893 and-list and or-list respectively instead of phrase search.
1897 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1898 log_mask_str. This was done to avoid name conflicts with other libraries
1899 (such as other PHP extensions).
1901 Added raw OID member for preferred record syntax (request_format_raw)
1902 and returned record syntax (output_format_raw) for backend fetch method.
1904 Config file yaz-config now accepts options so that it returns specific
1905 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1907 Shared library support for UNIX using GNU libtool.
1909 * Modified backend interface. Request/Response struct's replaced by
1910 one read/write C struct. For example bend_fetchrequest and
1911 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1912 Every handler - even search has to be registered in bend_init
1913 handler. This means that the YAZ library no longer refers to
1914 external functions and it makes it possible to make the whole
1915 thing a single DLL/SO.
1917 Added Segment handler for backend server.
1919 Added Zmbol/Zebra administrative functions to YAZ client.
1921 Threaded frontend server on UNIX (when POSIX Threads are available).
1922 Starting the server with option -T enables multi-threading.
1926 Added configure option --enable-comp/disable-comp to control use
1927 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1928 located in sub directory asn.
1930 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1931 in ${exec_prefix}/bin along with the other programs yaz-client and
1934 GNU automake used to maintain makefiles.
1936 Added several OID's.
1938 Changed retrieval module so that we can load records with no abstract
1939 syntax defined. Tagpaths in these records are fully composed of string
1942 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1946 On UNIX, the generated makefile now supports a proper 'make install'.
1947 The prefix can be set via GNU configure to set the install location
1948 (default is /usr/local).
1950 * YAZ programs client and ztest were renamed to yaz-client and
1951 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1952 locations, such as /usr/bin,/usr/local/bin,etc.
1954 * YAZ Header files were moved from include to include/yaz. YAZ Header
1955 files are referred to as include <yaz/log.h> rather than <log.h>.
1956 The YAZ include path (-I ..) is therefore the same as before. Programmers
1957 should update their #include statements or use -Ipath/include/yaz
1958 instead. The main motivation for doing this change is that YAZ header files
1959 can be installed in "standard" locations /usr/include,/usr/local/include
1960 without introducing conflicts, since ALL YAZ header files are stored
1961 in subdirectory yaz (under /usr/include for example).
1963 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1964 rather than project/workspace files. We switched because project files
1965 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1968 Changed name of logging function, logf, to yaz_log, to prevent name
1969 clash with some math-log functions. The YAZ header log.h defines logf
1970 to yaz_log (#define) so there should be no incompatibilities by this
1973 Added bend_start/bend_stop handlers for server. These handler are
1974 called on start/stop of server. For windows they are called whenever
1975 a service is started/stopped.
1977 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1978 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1979 in util/yc.tcl. The auto-generated C code structures are, in a few
1980 cases, incompatible with the old decoders. There are differences in the
1981 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1982 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1983 The preprocessor variable ASN_COMPILED is defined when the compiled
1984 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1985 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1986 wish to use the old encoders/decoders you can specify --disable-yc
1989 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1990 version so that it supports both new - and old version of DB Update
1992 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1993 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1994 change. The name parameter can be set to 0 in which no name is specified
1995 for the construction. The macros odr_implicit and odr_explicit sets name
1996 parameter to zero for the construction involved. New macros
1997 odr_implicit_tag and odr_explicit_tag are similar to the others,
1998 except that a name parameter is added. For programmers' that don't use
1999 ODR they probably only need to change the call to z_APDU and z_External.
2001 Added access control facility by interfacing the TCP wrapper library.
2002 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2003 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2004 name of the daemon and enables the access control as specified in
2005 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2007 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2008 den Dool <H.M.vdnDool@kub.nl>.
2010 Added reference ID parameter to most functions in server API - refer
2011 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2013 Changed name of ccl library to libccl.a (was ccl.a).
2015 Fixed bug in decoder for Explain (Category TargetInfo).
2017 Added support for GNU readline in client. Thanks to Jacob Poulsen
2018 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2020 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2021 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2022 IMPLEMENTATION! This change was made to the development version before
2023 the ZIG decided to retract the amendment. If any users MUST be
2024 compatible with the original Update definition, PLEASE CONTACT US, and
2025 we will include a separate definition corresponding to the old Update
2026 ES. Note that because of the change to the ASN.1 of the
2027 TaskPackageRecordStructure we cannot define a single structure that
2028 will support both versions.
2030 * Added const modifier to buffer parameter for some ODR/BER encoding
2031 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2032 completeWAIS, odr_dumpBER.
2034 Fixed bug in client.c which caused a crash when a scanResponse didn't
2035 contain positionOfTerm.
2037 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2038 * will cause an error in a client if a non-YAZ target sends both a
2039 * list of Scan entries and non-surrogate diagnostics.
2041 Retrieval module enhancements. Tag sets may be typed in the reference
2042 to it. From the .abs-file the "tagset" directive takes a third optional
2043 integer type for the tag set referenced. From a .tag-file the "include"
2044 directive takes a third optional type as well. The old "type" directive
2045 in the tag set itself is still recognized but acts as the default type
2048 Backend interface change. Individual Scan terms returned from bend_scan
2049 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2050 in include/backend.h.
2052 Retrieval module enhancements. Multiple tag sets and attribute sets may
2053 be specified in abstract syntax specs. Revised the error/warning for
2054 logging messages reported by the retrieval module when reading the
2057 Object Identifier system (oid_..) changed. The API is backwards
2058 compatible but the oid-routines now allocates new OID's when needed.
2059 Raw OID's may be specified in oid_getvalbyname.
2061 YAZ now uses GNU configure to generate Makefile(s).
2063 * Minor changes in some of the member names of DeleteResultSetRequest and
2064 DeleteResultSetResponse. See include/proto.h.
2066 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2067 and added member 'languages' in TargetInfo (which was missing).
2069 Changed the way attribute sets are handled in the retrieval
2070 module. These are now cached, just like the abstract syntaxes
2073 Changed YAZ so that it links with compiled ASN.1.
2075 Added Explain-schema definitions and mapping routines. The following
2076 Explain categories have been implemented: AttributeDetails,
2077 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2079 Fixed minor bug in Windows version of Server Library.
2081 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2083 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2085 Added EXTERNAL: UNIverse Resource Report (non-standard).
2087 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2088 ENUMERATED and SET OF.
2090 * Added 'const' to some of the char pointer arguments for the
2091 functions, data1_read_node, data1_getelementbytagname,
2092 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2095 Fixed bug in data1_insert_taggeddata - the last_child member of
2096 parent wasn't initialised.
2098 * Changed data1_read_record and data1_read_node so that the supplied
2099 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2100 doesn't refer to any parts of the "SGML"-buffer.
2102 Fixed bug in server library (Windows version of statserv_remove).
2104 * Changed code so that it compiles as C++. The type definition
2105 of Odr_fun which is a member of Odr_arm was changed. The result is,
2106 that an explicit typecast is needed for the fun pointer when
2107 using Odr_arm - as in:
2108 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2110 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2112 Implemented the new structured date and time definition as approved
2113 by the ZIG. Added schemaId element to the specificTag in Espec-1
2114 (also approved at the last ZIG). Thanks to RVDM.
2116 Added some Object identifiers (RVDM).
2118 Changed the Update Extended Service (RVDM).
2120 Added command "refid" to client which specifies referenceId for
2121 the following requests.
2123 Implemented extended service handling for server. See ztest.c
2124 for an example as well as backend.h. New handlers are registerd
2125 in the Init handler.
2127 * Changed interface for sort in server.
2129 Added new members to statserv_options_block. It allows a server
2130 to read options from another source than just the command line. Thanks
2131 to Charles Woodfield.
2133 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2134 renamed to zboolean. Some C++ compilers complained about the name.
2136 Minor changes to gils.abs. Added index 's' (sort) on title
2137 and date/time-last-modified.
2139 --- 1.4pl2 1998/1/30
2141 Fixed bug in server library regarding inetd mode (-i). This bug
2142 was introduced by release 1.4.
2144 --- 1.4pl1 1998/1/29
2146 Added sort facility in client and backend server interface.
2148 Fixed problem with dependencies in Makefile(s).
2150 Fixed bugs for encoders/decoders of extended services and
2153 Implemented sub-tree feature for schemas. Sub-trees are
2154 referenced in *.abs-files. See explain.abs for an example
2155 of the use of this feature.
2157 Modified bib1.att; local attributes for ANY didn't include
2158 ANY itself (only affects use of the retrieval module).
2160 Fixed bug in plain SGML reader in function data1_read_node:
2161 tags with prefix "var" was incorrectly interpreted as variants.
2163 Added feature "sub-schemas" to enable references to - and definitions
2164 of - group of elements.
2166 * Removed member parent from type data1_element (in data1.h).
2168 Implemented function odr_nullval() that returns the value of
2171 * Removed member num_children from data1_node (in data1.h).
2173 Made NT service interface part of the server library. The
2174 function statserv_main uses the NT service when required and
2175 calls the statserv_start / statserv_close routines.
2177 Routine zget_SearchRequest and zget_PresentRequest fills
2178 resultSetName/Id member with "default" instead of "Default".
2180 Fixed memory leak in server. Request queue member wasn't freed.
2182 Fixed nmem_exit so that memory is freed.
2186 Revised the CCL parser utility to be thread safe.
2188 Added function, oid_ent_to_oid, to replace the function
2189 oid_getoidbyent, which is not thread safe.
2191 * Added nmem_init and nmem_exit to initialize and release
2192 NMEM resources. Function nmem_init should be called once in the
2193 initial thread before NMEM/ODR is used. statserv.c and client.c
2194 have been changed accordingly. The change was necessary to make
2195 NMEM thread safe. The NMEM memory pool is shared amongst threads
2196 in a process. Unix-based applications will still work fine without
2199 Added NT Services interface for the the Z39.50 (statserv) Server.
2200 Refer to the ztest.c source on the usage.
2202 Windows 95/NT port using MSVC5.0. Project files are included in the
2205 * Defined new 'global' handle for the retrieval (data1) system. The
2206 new handled, data1_handle, describes the state of the data1 system.
2207 This handle is passed as first argument to virtually all
2208 data1 related routines. The functions data1_create and data1_destroy
2209 creates and destroys a data1 handle respectively.
2211 Added ODR encode stream member to all backend request structures
2212 init, search, scan etc. This stream should be used to allocate all
2213 memory used for the response when thread safe operation is needed.
2215 Changed the comstack utility, cs_addstr, to be thread safe. The
2216 returned hostname string returned by the function is now part the
2219 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2220 function. The cs_straddr takes a COMSTACK handle as argument, so this
2221 function must be used after cs_create and before bind/connect.
2222 This function is thread safe.
2224 Moved test server to 'ztest' directory - generic server code still
2225 in 'server' directory.
2227 Made prefix query (pquery.c) utility thread safe.
2229 Added new function modifier YAZ_EXPORT to 'export' public DLL
2230 functions when using windows (see include/yconfig.h).
2232 Added definitions to the OID database (util/oid.c) (RVDM).
2234 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2236 Added call to ccl_rpn_delete in client program.
2238 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2239 release of RPN structure.
2241 Added support for C++, headers uses extern "C" for public definitions.
2242 With input from RVDM.
2244 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2245 Thanks to Ronald van der Meer (RVDM).
2247 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2249 Added support for private extensions to the OID database
2250 (oid_setprivateoids()). Thanks to RVDM.
2252 Added optional, physical ANY (key replication)
2254 Fixed null-reference problem in GRS-1 output filter.
2256 Proximity operator added to Prefix Query Format (PQF).
2258 In test client command "base" accepts multiple databases.
2260 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2264 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2266 Smallish bug-fixes in the new encoders/decoders (explain).
2268 Bug fixed in DeleteRequest.
2270 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2272 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2274 Added SOIF syntax (using private OID for now) to retrieval module and client.
2276 Added Update extended service.
2278 Added SearchResult-1 additional info structure.
2280 Added optional CCL (ISO8777) interpreter as separate module. Available
2283 --- 1.2 1996/6/10 (1st anniversary release)
2285 Added Summary record syntax. Lightly tested.
2287 Added OPAC record syntax. Untested.
2289 Added ResourceReport service encoders/decoders. Untested.
2291 Fixed bug in z_Unit - wrong tagging on unitSystem.
2293 Fixed bug in the DiagRecs decoder.
2295 Added options for max PDU size and session timeout to frontend-server.
2297 Added documentation of query-language parsers and other supporting utilities.
2299 [frontend-server] Added Attribute set to the bend_scanrequest API.
2301 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2302 surrogate diagnostics were generated.
2304 [retrieval] Allow multiple local values for attribute.
2306 [retrieval] Allow multiple attributes per element in .abs files. index type.
2308 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2310 --- 1.1pl2 1996/4/10
2312 Minor changes, mostly specific to Zebra's requirements (retrieval)
2316 Repaired bug in frontend server when running multiple listening
2317 endpoints in dynamic mode.
2319 z_External() now won't break if a known, ASN.1 value comes encapsulated
2320 in an octet-string. The value will pass through unmodified in an Odr_oct.
2322 Added a bit of code to the demo client to decode & display
2323 ASN.1-structured records represented in the octet-aligned branch of
2324 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2326 Added z_ext_getentbyref() to the ASN module. Doc updated.
2328 * Completed the SCAN definition in the ASN module. This may break SCAN
2329 code based on older YAZ-versions at compile-time. The fix is easy -
2332 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2333 under the SCAN definition. Remember to initialize this, server-people.
2335 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2336 that this does not extend to ODR and ASN.
2338 Comstack allows insertion of established socket (primarily for
2339 inetd-operation of servers). Doc updated.
2341 Front-end server can now start from the inetd in TCP mode. Doc
2344 --- 1.0pl4 1996/1/24
2348 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2349 the rank and record number.
2351 Adjustments to the frontend server.
2353 Fixed diagnostic BER dumper. It ignored the file argument.
2357 Various changes to retrieval module.
2359 Changed the union discriminators of the protocol files from enums to
2360 ints paired with #defines.
2362 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2365 *Changed operator in the RPN structure to 'roperator', again to avoid a
2368 Fixed problems in Explain decoders/encoders.
2370 --- 1.0pl2 1995/12/6
2372 Memory bug in log module fixed.
2374 --- 1.0pl1 1995/12/5
2376 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2378 Bug in Explain DatabaseInfo module fixed.
2380 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2384 The shift to v1.0 signals that we now consider the *core* functionality
2385 of YAZ reasonably stable (the core being more or less equivalent to
2386 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2387 tested (Explain not at all - though that will happen soonish).
2389 Minor changes to code to support Windows port.
2391 Various minor changes after we're getting to use GRS-1 & co. more.
2393 Added Espec-1 format.
2395 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2396 of the protocol and it cannot be selected when encoding (maps into 'string'
2397 when decoding). Needed to talk to some servers.
2399 Demo client can request simple element set names.
2401 Added Diagnostic Format encoders/decoders.
2403 Added simple Close handling to frontend server (no hooks for resource
2404 reporting yet), and demonstration client.
2406 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2408 --- 1.0b3 1995/08/24
2410 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2411 handled incorrectly when records were requested in the searchResponse. This
2412 will only affect you if you use the frontend-server.
2414 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2415 Test-client will ask for and print GRS1. Ztest will return dummy records
2418 Added Explain encoders/decoders to the service-level API. Untested.
2420 Added Extended Services: Item Order encoders and decoders to the Service-
2421 level API. Untested. We could use a recent copy of the pertinent bits
2422 of the ILL protocol to add those bits.
2424 Added diagnostic format 1 encoders/decoders to the service-level API.
2427 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2428 odr_cons.c, which causes a more correct output.
2430 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2431 was always set to 0 when no records were requested in the searchRequest.
2433 * Added better external-handling. This shouldn't harm old code that
2434 *encodes* externals. It can break code that looks for a
2435 'single-ASN1-type' representation, since those types that are known
2436 are now decoded immediately. Look at the SUTRS sample code in
2437 seshigh.c and client.c. Documentation updated.
2439 Handling of structured records in bend_fetchresponse. Length -1 marks
2440 structured record, type is deduced from format field.
2442 --- 1.0b2 1995/06/27
2443 Fairly quick maintenance release to add SUTRS support.
2445 Fixed handling of SUTRS records in the demonstration client.
2447 * Added format field to the bend_fetchrequest and bend_fetchresponce
2448 structures of the backend API (frontend server). When the record is
2449 returned, the value of the format field is mapped to an OID. The
2450 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2451 of the record. The special value VAL_NONE in the bend_request means
2452 that no specific format was requested by the client. Documentation
2453 updated accordingly. Test server (ztest) will return a fixed dummy
2454 SUTRS record if your client requests SUTRS.
2456 Documentation updated accordingly.
2458 You can now set external libraries and RANLIB support in the top-level
2462 First public release.
