1 ZOOM_record_get now renders OPAC records when type=xml. Previously
2 only the bibliographic record was rendered. For type=opac, an OPAC
3 record is only returned if it is present.
7 Fixed bug #2709: TCP connect returns Invalid argument.
9 Fixed compilation for mingw.
11 Honor charset for raw records (ZOOM_record_get).
13 Fixed use of errno for threaded mode that was seen on Solaris 10.
15 Fixed argument passing with blanks in value for Windows Service.
17 Disable YAZ' own log rotate by default (no 1 GB limit).
18 The variable l_max_size which specifies the log file limit is set to 0
19 (DISABLED): This is due to the fact that YAZ is most often deployed using
20 logrotate. Also YAZ can not perform log rotate because of unsufficient
25 List supported encodings in man page for yaz-iconv.
27 Fixed missing SSL libs for --libs output
29 Re-established OID record syntax application-xml. Nobody should use it
30 but we don't want to change soname because of this symbol being absent.
34 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
36 Added member named_result_sets for init handler struct for the GFS. This
37 allows a server to disable named result sets.
39 Removed OID record syntax application-xml.
41 Added support for rule-based transliterator for ICU wrapper of YAZ.
43 Fixed bug #1902: yaz-icu XML output.
45 Make YAZ checks Emacs friendly.
47 BITSTRING value shows value. Bug #2346.
49 ISO2709 decoding: skip control characters from indicator data.
51 Omit sort key by default in yaz-icu's output.
53 Allow combined single char options (again) for YAZ' options function.
55 Utility yaz-marcdump got option to display YAZ version (-V).
57 Allow YAZ to use ICU 3.4.
59 Added new ICU test case which illustrates removal of diacritics.
63 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
67 For configure, using option --without-xml2 also disables Libxslt/Libexslt
70 Fixed bug #2352: yaz-marcdump crashes for certain record.
72 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
74 Added support for Danmarc2 to UTF-8 conversion.
76 Added support for ISO5426 to UTF-8 conversion.
78 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
79 implementation version.
81 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
85 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
86 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
88 ZOOM C now interprets databaseName option for ZOOM connection as path
91 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
93 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
95 Dummy Libxml2 types no longer defined in headers of YAZ'.
97 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
100 --- 3.0.36 2008/09/26
102 Various ODR chapter fixes.
104 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
106 Added missing source for Windows compilation, mutex.c.
108 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
110 For SRU connections in ZOOM all records up to "count" are now fetched.
112 Fixed crash in generic frontend server (and yaz-ztest) which occurred
113 in Windows due to bad error handling for Libxml2.
115 Added facility for sending arbitrary records (ASN.1 any) using
116 ZOOM C's Extended service update. Patch by Sam Reynolds.
118 New options for ZOOM C's connection, logapdu which makes ZOOM log
121 --- 3.0.34 2008/06/18
123 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
125 --- 3.0.32 2008/06/12
127 Fixed memory violation that could occur when decoding UTF-8. This bug
128 was only present in 3.0.30 of YAZ.
130 --- 3.0.30 2008/06/06
132 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
133 GNU TLS is used by default (if found).
135 yaz-ztest returns OPAC records if a client asks for OPAC.
137 Improved speed of MARC-8 encoding.
139 Added support for lossy and loss-less MARC-8 encoding.
141 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
143 Added new Windows Service wrapper (sc).
145 yaz-client's itemorder command may now send a file.
147 Fixed yaz-marcdump to allow the use of NS prefix for record element.
149 Added new function yaz_log_xml_errors.
151 Allow (but warn) unknown XML attributes in MARCXML parsing.
153 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
155 The UTF-8 to MARC-8 conversion now uses a different set of characters
156 for Greek symbols. Bug #2120.
158 --- 3.0.26 2008/02/21
160 Added yaz_daemon (daemon.h).
162 Fixed bug #2068: pkg-config trouble
164 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
166 --- 3.0.24 2008/01/28
168 Document --with-xml2 option.
170 Added OPAC XML XSD (etc/opacxml.xsd).
172 Allow glob mask for name attribute in retrieval element for the
173 generic frontend server's retrieval facility.
175 Changed yaz_poll_poll to return yaz_poll_except for all returned events
176 except POLLIN/POLLOUT.
178 Fixed error handling in cs_listen. Bug #2037.
180 --- 3.0.22 2008/01/20
182 Fixed version in yaz/yaz-version.h.
184 Fixed bug #2027: Crash when closing connection.
186 Changed configure so that ICU support is only enabled if only ICU
187 and Libxml2 is available (because the ICU chain is XML based).
189 --- 3.0.20 2008/01/15
191 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
192 is built. Only this DLL depends on the ICU runtime.
194 yaz-ziffy is no longer part of YAZ. It is distributed separately by
195 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
197 Changed license of CCL module to 'Revised BSD'. After consultation with
198 remaining members of the original EUROPAGATE consortium, we are re-issuing
199 the CCL module without a separate license. The software was developed by
200 Index Data as part of a research project. The special license was included
201 to help feed usage information back to the project consortium to support
202 project evaluation. At this time, the project consortium has long-since
203 disbanded, and the majority of the original principals have retired. At the
204 same time, we have significantly modified the software during the following
205 years, to the point where very practically no original code remains. To
206 simplify re-use of the software, we have contacted those members of the
207 consortium who could be reached, and agreed to re-issue the module as a
208 proper part of the YAZ package.
210 Tcl scripts uses /usr/bin/tclsh as preferred shell.
212 CQL closer to being version 1.2 compliant. CQL also allows free-form
213 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
216 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
217 bug could make Extended services handling crash in the ZOOM layer. This
218 bug was only present in YAZ 3.0.18.
220 --- 3.0.18 2007/12/19
222 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
225 yaz-marcdump reads and writes collection wrapped records.
227 Handle OPAC for record conversion module.
229 Fixes for ICU wrapper.
231 Allow ICU libs to be controlled with --with-icu .
233 --- 3.0.16 2007/11/12
235 Added yaz_poll which is a wrapper for select/poll. When poll is available
236 and non-buggy, it is used, by yaz_poll . This allows more than 1024
237 sockets to be in use.
239 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
240 functionality through an XML based configuration (ICU chain). This system
241 is useful for search facilities such as Pazpar2 and Zebra that needs to
242 perform tokenization of indexed material. The ICU code in a separate
243 library libyaz3_icu.a.
245 Added HTTP tunnel facility for COMSTACK, bug #1752.
246 This is a facility that allows a Web proxy, such as squid, to tunnel
247 Z39.50 traffic. This facility is "transparent" to must applications
248 using YAZ. It's enabled by using pseudo transport connect: followed by
249 the proxy address, followed by command, then follwed by he regular
250 "virtual" addresss. For example,
251 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
253 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
255 --- 3.0.14 2007/09/21
257 Fixed bad memory reference in ZOOM_record - cuased by member not being
258 initialized. This was a problem only in YAZ 3.0.12.
260 Fixed bug in conversion from MARC to XML: Non-XML characters in control
261 fields were not removed.
263 Changed the way C code is generated from codetables.xml. Made a MARC-8
264 conversion trie for each characterSet section rather than codeTable.
265 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
266 of codetables.xml from Larry Dixson, LOC. Bug #1464.
268 --- 3.0.12 2007/09/12
270 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
271 from ZOOM_record_error).
273 ZOOM C function ZOOM_record_get returns record schema for type="schema".
275 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
277 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
279 Better SRW-to-Bib-1 diagnostic mapping.
281 ZOOM C and yaz-client announces SRU version 1.2 by default.
283 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
286 Fixed in yaz_sru_decode to allow other version than 1.1.
288 --- 3.0.10 2007/08/22
290 Added support for SRU scan for ZOOM.
292 Added support for the use of the older versions or Extended Service
293 Update in ZOOM. To faciliate this, an option "updateVersion" may be
294 set to the version , 1=first, 2=second, 3=third. The third version is
295 what ZOOM C has used so far. And that, obviously, is the default.
297 Added support for CCL queries in Z39.50 queries sent to the GFS (and
298 therefore in Zebra and in SimpleServer-based applications). The new
299 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
300 qualifier file used to transform incoming CCL queries into Type-1 RPN,
301 which is passed into the back-end search callback function.
303 Added support for HTTP Basic authentication in clients: the SRU/W
304 codec encodes the username/password elements of the PDU structure
305 appropriately, and these may be set using the "user" and "password"
306 options in ZOOM-C applications (the same options that are used for
307 Z39.50 authentication).
311 Fixed bug #1208: SSL appears to be broken in ZOOM.
313 Fixed bug #1206: Libxml2 include path weirdness.
315 Added oid_name_to_dotstring.
317 Allow elementSetName to be specified for ZOOM C record update.
319 Allow waitAction to be specified for ZOOM C based for Extended Services.
321 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
322 syntax OID. Bug introduced in YAZ 3 series.
324 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
328 Fixed bug #1157: yaz-client does not read .yazclientrc from current
329 directory. yaz-client now reads commands from file given by option -f
330 if specified; then tries to read .yazclientrc in current directory.
331 Failing that, it reads .yazclientrc from user's home directory.
333 Added support for correlationInfo Note and ID for Record Update via
336 Added yaz-client command querycharset which specifies character set for
337 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
338 (termListAndStartPoint).
340 Charset ISO5428:1984 is an alias for ISO5428-1984.
342 Implemented a way to perform scan in a result set using Z39.50. This
343 is achieved by attaching the result set name in the characterInfo
344 (type InternationalString) of OtherInformation in the Scan Request PDU.
345 The result set is identified in the otherinformation by the new OID:
346 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
347 This allows for scan in result set and faceted search . Zebra did some
348 of this in the APT term using attribute type 8 and value being result
349 set. Using the OtherInformation approach for this is cleaner and easier
350 to work with in proxies and the like. This facility can be used in
351 yaz-client using new command setscan which takes a result set as first
352 argument, start position (APT) as second.
354 Changed decoding of SRU XML packed records to deal with servers that
355 have recordData with XML data with multiple root nodes. Also make
356 comparison for recordPacking case insensitive. Again, one server
357 returns "XML" where others return "xml".
359 For SRU responses allow Content-Type application/xml as well as text/xml.
363 Fixed bug in character set conversion of BER strings. Bug introduced
368 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
370 For OID class, use oid_class consistently.
372 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
375 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
376 character set for bibliographic information interchange". By Giannis Kosmas.
378 Added documentation on new OID API.
382 Changes to generic frontend server interface: added new member
383 'query_charset' for bend_initrequest structure. A backend init handler
384 should set this member to its native character set for query terms.
385 When defined, the frontend server logic will announce this character set
386 to a client if the negotiationModel bit is set by the client. All server
387 implementors are encouraged to specify this. If a backend server does not
388 specify this a warning is issued using yaz_log(YLOG_WARN,..).
390 Added CCL utility to remove terms (stop words) from resulting RPN
391 tree. This is handled by functions with prefix ccl_stop_words_ .
393 New ZOOM C option, "rpnCharset", which allows client-side conversion of
394 terms in RPN queries.
396 Clean-up the CCL API. Moved some internal structures from ccl.h to
397 private header cclp.h. Changed ccl_parser_create so that a Bibset must
398 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
399 This is replaced by ccl_parser_find_str which takes a string instead.
401 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
402 libyaz.la is the core of YAZ except the generic frontend server and
403 does not depend on POSIX threads anymore. libyaz_server.la is the
404 generic frontend server facilities and uses POSIX thread functionality
405 if available. The libyaz.la no longer depends on POSIX threads because
406 the number of global structures is limited. NMEM no longer re-uses blocks
407 between threads ; it simply free's memory immediately but allocates in
408 "large" chunks as usual. We don't expect any performance penalties
409 because of this. The yaz_log system is still using a global log_level so
410 caution must be taken when modifying it with yaz_log_init_.. +
411 yaz_log_mask_str. This, however, should not cause any trouble because
412 these functions are called during initialization of application code
413 anyway. `yaz-config --libs server` returns libs for server applications;
414 `yaz-config --libs` returns libs for non-server applications.
416 New OID database - with public definitions in oid_db.h. Removed old OID
417 database including the head oid.h and definitions such as enum oid_value
418 and struct oident. The new OID database uses the same string names as
419 before but the 'protocol' is gone. There are now only two representations
420 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
421 converts from string to OID; functions with prefix yaz_oid_to_string
422 converts the other way.
424 Change to emit_term() in CQL-to-PQF query translation: when a term has
425 the /regexp relation modifier, do not process it for leading and
426 trailing "^" and "*", which have quite different meanings in regular
429 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
430 write handlers no longer carries a 'last' parameter. This will make
431 yaz_iconv flush "less" characters. A flush is performed by call to
432 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
434 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
435 removed, because function yaz_query_to_wrbuf does the same.
437 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
438 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
440 Deprecated MARC utility functions removed.
442 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
445 Branch split: YAZ_2_1_55_branch
447 --- 2.1.54 2007/03/16
449 Fix to ZOOM-C so that transparent reconnection is properly handled on
450 connections that are in asynchronous mode.
452 Fixed compilation on OpenBSD 4.0.
454 Large strings in GRS-1 records are now properly displayed in yaz-client.
456 Added character conversion support for "advancegreek"; based on patch from
459 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
460 sequence is met. Before the error was not set so it would be unknown.
462 Adjust yaz-marcdump MARC reader so that it skips until record separator
465 --- 2.1.52 2007/03/07
467 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
468 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
469 fd_set structure used as a bitmask for the FDs to be selected on.
471 Using ACX_PTHREAD macro to check for POSIX threads.
473 Fixed have-vsnprintf check.
475 --- 2.1.50 2007/02/23
477 Fixes for configure on BSD. Bug #900.
479 Added snprintf/vsnprintf wrappers for systems that don't have
480 limits (heavens forbid).
482 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
483 created before all previous tasks were completed and removed from the
484 task queue, the new task could be removed by a mistake.
486 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
488 Implemented pass-through CQL-to-PQF conversions. Bug #861.
490 Fixed bug #832: Problem with MARC/charset in yaz-client.
492 Fixed bug #668: save command line history for yaz-client.
494 Fixed bug #830: pkg-config support.
496 --- 2.1.48 2007/01/23
498 Extended ZOOM result set options with two options that may be read by
499 a client: resultSetStatus and presentStatus with values as specified for
501 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
503 Fixed bug #827: Using SSL fails on Debian etch.
505 Fixed bug #826: Weird looking chars for set of MARC records.
507 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
508 that is treated as an ItemOrder with itemRequest being an XML document
509 external. The value of "doc" is the content.
511 Extended the GFS search facility. New member of bend_search_rr
512 'estimated_hit_count' signals that hits is known to be an estmate
513 (higher or lower than real hit count). New member 'partial_resultset'
514 signals that the search was partial (hit count is lower or equal than
515 real hit count). For Z39.50, the information is stored in resultSetStatus
516 member of SearchResponse APDU. For SRU, the information is signalled
517 via SRU diagnostic 59: "Result set created with valid partial results
520 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
522 --- 2.1.46 2007/01/13
524 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
526 Added ZOOM_connection_peek_event.
528 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
529 the following new functions:
530 ZOOM_event_nonblock, ZOOM_connection_process,
531 ZOOM_connection_get_{socket,mask,timeout},
532 ZOOM_connection_fire_event_{timeout,socket}.
533 The existing blocking event handler, ZOOM_event, is a wrapper for the
534 + blocking ZOOM_event_sys_{poll,select}.
536 Implemented function ccl_xml_config which parses XML version of CCL
537 configuration (bug #798).
539 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
541 Added timings utility (yaz/timing.h)
543 --- 2.1.44 2007/01/03
545 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
548 Fixed bug #779: Rotation of apdu.log fails.
550 Fixed for character set conversions:
551 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
552 Honor G1 set in MARC-8 decoding.
554 --- 2.1.42 2006/12/17
556 Fixed bug #775: char conversion does not handle Alternative UTF-8
559 Implemented function yaz_marc_read_line which parses MARC line format
560 records. There is a wealth of formats out there. So far, this function
561 reads line records produced by yaz_marc_write_line.
563 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
564 more generic and easier to remember(!) options: -i format and -o format
565 which specifies input format and output format respectively - where
566 format is one of "marc", "marcxml", "line", "marcxchange".
568 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
569 does not print anything except warnings for records.
571 For yaz-marcdump, added support for MARC split into files (-s) with a given
574 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
575 spec, at http://www.loc.gov/standards/sru/record-update/
576 This has changed the binary layout of the following structs:
577 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
578 bend_update_rr . Patch by Ko van der Sloot.
580 Added GFS utility function bend_assoc_is_alive which returns 1 if
581 association is still alive (client is connected); 0 otherwise (client
582 closed connection). This allows busy servers to stop working for
585 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
586 been a separate piece of software. This version of ziffy has been modified
587 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
589 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
591 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
592 Client code may now interrogate options such as "init_opt_sort" to
593 find out whether the server claims to support various options.
595 --- 2.1.40 2006/11/27
597 Added utilities yaz_{set,get}_esn to set/get element set name from
600 Removed the build of libyazthread.la. The libyaz.so is the threaded version
601 of YAZ and has been so since YAZ 2.1.10.
603 Implemented ZOOM_record_error which returns error information for
604 record (surrogate diagnostic).
606 --- 2.1.38 2006/10/31
608 Updates for SRU Update by Ko van der Sloot:
609 1. Changed name from "operation" to "action"
610 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
611 versions in the code, marked as 'backward compatible'.
612 3. Added diagnostics for SRU Update.
614 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
616 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
618 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
620 For GFS, fixed problem with SRU diagnostic 'First record position out of
621 range' being issued for 0 hits.
623 zoomtst10 part of Windows Build.
625 --- 2.1.36 2006/10/13
627 Implemented yaz_filepath_comp which splits a path into file path
628 components (required by Zebra 2.0.3+).
630 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
631 BSD inspired license until now so this should not have any real impact on
632 anybody. See http://www.opensource.org/licenses/bsd-license.php
634 Fixed bug #687: Missing log lines.
636 Fixed bug #678: CQL to PQF translation does not preserve double-quote
639 Fixed bug #689: SRU diagnostics to be added.
641 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
642 whether a connection is idle (no more work do do).
644 --- 2.1.34 2006/10/04
646 Change type of optval from long to int for invocation of setsockopt with
647 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
649 Added support for specifying the max log file size for the Generic
650 Frontend Server. The size is given with option -r.
652 --- 2.1.32 2006/09/21
654 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
656 --- 2.1.30 2006/09/17
658 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
661 Fixed bug in Generic Frontend Server that could cause a server to stop
662 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
664 For the generic frontend server, the maximum record size is used as maximum
665 size of incoming packages (SRU + Z39.50). The value until was previously
666 only used in Z39.50 Init negotiation and, later, in a session controlled
667 sizes of records returned. This is controlled using -k option. It can be
668 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
670 --- 2.1.28 2006/09/04
672 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
675 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
677 New option for yaz-marcdump -lpos=value which allows setting a portion
678 of MARC header to a certain value.
680 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
682 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
683 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
685 --- 2.1.26 2006/08/15
687 Fixed problem with SRU mode type (soap, get, post) for yaz-client
690 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
692 --- 2.1.24 2006/08/08
694 Fixed MARC ISO2709 encoding routines to deal with character set
697 Minor changes to GFS logging. Database included in search request log
700 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
701 cached/multiple records.
703 Shared libraries are built by default on Unix+configure.
705 Changed cql2pqf transformation to use a different evaluation order. The
706 new order is: always, relation, structure, position, truncation, index
707 and relationModifier. Old order was: always, relation, relationModifier,
708 structure, index, position, truncation. Note that the the latter ones
709 override former ones for identical attributes.. The new scheme means that
710 it is possible to override any existing attribute with a relationModifier.
711 And also that it is possible to override everything for the index rule
712 (except the ones listed in relationModifier). No order is perfect but this
713 one, we believe, covers more real cases.. The "always" should have been
714 called "default", since the attributes there can be overridden with all
717 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
718 compilation phase, but also for yaz-config --cflags output. This allows
719 us to have public headers with Libxml2 stuff in them . It should also,
720 eventually, make Libxml2 checks redundant in packages using YAZ, such
723 --- 2.1.22 2006/06/15
725 Changed SRU update structure bend_update_rr so that SRU diagnostics are
726 stored in uri, message and details.. Previously diagnostics were stored
727 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
728 compatibility.. but he's probably the only one affected, so.
730 Added support for CCL, compiled on the client side, in ZOOM-C. This
731 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
732 input; the resulting query objects can be used for for searching with
733 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
735 YAZ' configure searches for OpenSSL by default.
737 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
738 SL_CTX_use_certificate_file. See
739 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
740 for more info. Thanks to Ko van der Sloot.
742 --- 2.1.20 2006/06/02
744 Bug #600: SRU GET, POST support for yaz-client. Introduced
745 command 'sru' which selects method SOAP/GET/POST.
747 Allow missingValueAction to be specified for the sortspec string -
748 function yaz_sort_spec. By default, the missing value action is null.
749 Use ! to specify "abort". Use = followed by stringvalue to specify default
752 Ensured that Present-handler (if defined) is called in GFS before any call to
753 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
754 searchRetrieve requests.
756 Documentation for YAZ is now based on the Docbook XML/XSLT using
757 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
758 is no longer depending on jade/openjade or docbook-to-man scripts.
759 PDF is no longer part of the distribution - but can optionally be
760 made using DSSSL/jadetex or FOP.
762 Added retrieval handling support in Generic Frontend Server to support
763 conversion between MARC/XML as well as XSLTtransforms. See
764 etc/yazgfs.xml for an example.
766 Added Authentication support to Generic Frontend Server in SRU
767 mode. Authentication using HTTP Basic is supported, as is the use
768 of 'x-username' and 'x-password' parameters in the request itself.
770 Added support for a new character set MARC8s identical to MARC8 except
771 that it converts combined characters to single Unicode characters in the
772 Latin-1 range (when possible).
774 --- 2.1.18 2006/04/24
776 ASN.1 compiler 0.4: generates brief Doxygen file header for
777 generated .h/.c files.
779 Utility yaz_iconv now supports conversion to MARC-8.
781 New facilities for the MARC module. The reading - and writing of
782 content are separate methods for the yaz_marc_t handle. The following
783 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
784 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
785 format). Write functions have prefix yaz_marc_write_.. The existing
786 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
787 available. Removed support for OAI-MARC and simplexml (not the
788 simplexml from PHP5).
790 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
791 to be returned for this connection.
793 --- 2.1.16 2006/03/31
795 Allow multiple languages and charsets to be specified with
796 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
797 negcharset iso-8859-1,utf-8
799 Translation of proximity nodes from CQL into PQF now works.
801 Moved to automake 1.8, 1.9.
803 Added function yaz_log_set_handler which allows a log handler to be
804 installed. This handler will be called for all log messages. Output
805 to file is also produced; but that can be disabled by passing NULL
806 fname to yaz_log_init_file.
808 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
810 For SRW (including GFS), accept application/soap+xml as content-type
813 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
814 produces NO stylesheet reference even if a default stylesheet is specified
817 --- 2.1.14 2006/03/14
819 Updated Windows package to include yazd.dll + yazd.lib for the
820 Development component.
822 If the environment variable YAZ_LOG is set, then it is used as a
823 string indicating the default level of logging to use if not
824 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
825 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
826 used as before. So, for example, to omit warnings from YAZ logging,
829 cql_transform() now map structure and other attributes before indexes,
830 so that index-specific structures and other attributes can override
831 defaults. So now a combination of mapping specifications such as:
833 index.dc.date = 1=date-modified 4=5
834 does the right thing.
836 cql_transform() now also respects the "always" mapping specification,
837 which establishes an initial set of attributes to be used for all
838 terms except where overridden by more specific attributes associated
839 with the index, relation or modifier.
841 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
842 which mode to use; one of "post", "get" or "soap" (SRW, default).
844 Fixes for yaz_iconv routines: changed trie-based character set conversions
845 to use only non-negative values for bit fields due to Sun's C compiler not
846 supporting negative values.
848 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
849 sequences where not read correctly. Fix by Rustam Usmanov.
851 Updated win/makefile to use options, settings which makes things
852 compile with VS C 2005.
854 --- 2.1.12 2006/02/01
856 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
858 In ZOOM socket code, use select instead of poll on MacOSX.
860 ZOOM-C now support client-side compilation of CQL into RPN that is
861 sent to the server, enabling CQL to be used against all Z39.50
862 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
863 ZOOM_query object, and submit it using ZOOM_connection_search().
864 The CQL-to-RPN translation uses a configuration file, the name of
865 which must be specified in the Connection's "cqlfile" option.
867 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
868 function, which takes as its start-term parameter a ZOOM_query object
869 (which may have had either CQL or RPN set into it).
872 --- 2.1.10 2005/11/29
874 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
875 GFS to support this as well. Backend handler, bend_srw_update, does the
876 update work. Code contributed by Ko van der Sloot.
878 Allow retrieval of Search Result-1 information in ZOOM by the use of
879 options that are attached to a result set. ZOOM documentation updated
882 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
883 UTF-8 conversion. Patch by Raj Patel.
885 Added option -m to GFS to control formatting of timestamps in log file.
887 Added 'exit' as synonym for 'quit' in yaz-client
889 Added support for specifying SRW resultSetId + resultSetIdleTime in a
890 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
891 for the new members. Patch by Ko van der Sloot.
893 Added support for SRU POST. It is supported for content-type
894 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
896 Do not build the separate Multi-threaded (MT) library libyazthread.la.
897 Instead make the library libyaz.la multi-threaded. Threading as a whole
898 can still be disabled by configure option --disable-threads. Previosly,
899 with older GLIBCs there were problems with MT libs under Apache. This
900 has now been fixed a long time ago.
902 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
905 CQL module modified to be case insensitive for relations/indexes/operations.
907 Fixed bug in CQL transform code: incorrect value relationModifieder
910 Added 'show all' command for yaz-client which retrieves all results
913 Added new yaz-client, xmles, which takes a (private) OID and
914 a document to be sent as an extended service request.
916 Describe new yaz-client commands wait_response and set_auto_wait.
918 Increase TCP/IP listener backlog from 3 (which I am guessing was
919 copied from the SunOS manual entry way back when) so SOMAXCONN, so
920 that the socket will queue as many incoming connections as it's able
921 to handle ongoing connections. In other words, it will never now
922 refuse a connection that it would be able to handle merely because
923 it's not got around to accepting() enough of the pending connections
924 yet. This is the behaviour anyway under Linux, where the listen()
925 argument is ignored; but not under BSD and on systems such as
926 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
927 YAZ-based servers should now be uniform across operating systems in
930 yaz-marcdump uses 64-bit file access on some systems. This is enabled
931 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
932 This allows yaz-marcdump to read large MARC batches (>2 GB).
934 Modified all YAZ source files - except the source which is auto-generated
935 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
938 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
939 corresponding to the existing *_setl() function. These allow option
940 values containing arbitrary valuues.
942 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
943 ZOOM_resultset_sort() in new applications. Its behaviour is identical
944 except that it returns an indicator of whether or not the sort
945 criterion was accepted (0 for OK, -1 for invalid).
949 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
950 MARC output rather than returning "new" buffer.
952 yaz-client warns about unknown init options.
954 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
958 Added support for SRW sort in Generic Frontend Server. Patch
959 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
960 sortKeys - or NULL if none is provided.
962 Fixed bug #307: It was impossible to specify indefinite/no timeout
963 for ZOOM_event. Special timeout value -1 now means indefinite timeout
966 Added support for multiple languages and charsets to be specified in
967 ZOOM. Each charset/language is separated by a blank. If negotiation is
968 in effect in init-response, Option
969 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
970 Code based on patch by Vasiliy Osadchuk.
972 Fixed bug #306: infinite recursion that occurred when calling
973 yaz_log_level_init as the first call (before other log level or
976 Fixed bug in scan handling in front end server: if preferred-Position-In-
977 Response was non-present, a NULL pointer referece was performed.
981 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
982 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
983 now defined for all those error codes. So instead of putting 109 in
984 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
985 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
987 Modified the yaz-marcdump utility to skip garbage bytes between MARC
990 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
992 Program yaz-client now exits and produces an error message if multiple
993 Z39.50 servers are specified on the command line (none or one allowed
996 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1001 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1003 Fixed bug #272: Preserve spacing for CCL terms.
1005 --- 2.1.0 2005/03/14
1007 Added support for virtual hosts and multiple backend servers for
1008 the YAZ frontend server. The configution is XML based and
1009 support specificition of CQL to RPN mappings and explain information.
1010 See section "Virtual Hosts" in the YAZ manual.
1012 Extended OPAC display utility. OPAC display utility renders
1013 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1014 to supplement yaz_marc_decode_wrbuf.
1016 Fixed a bug in MARC decoder that could caused it to crash for some
1017 invalid MARC records. More diagnostics and warnings where added in
1018 XML output (warnings, etc are stored in comments).
1020 --- 2.0.34 2005/02/08
1022 Fixes for UNIX domain sockets. Bug #261.
1024 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1026 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1027 Added yaz_marc_subfield_str which defines subfield lead string which is
1028 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1029 yaz_marc_endline_str which defines end of fields string used in
1030 YAZ_MARC_LINE format. Default string is newline.
1032 Experimental support for MarcXChange. This format can be produced
1033 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1034 http://www.bs.dk/standards/MarcXchange.xsd
1036 Added yaz-client commands scansize that sets maximum number of
1037 entries to be returned by scan.
1039 --- 2.0.32 2005/01/11
1041 Added support for SRW scan in yaz-client and Generic Frontend Server.
1043 * Added whereInList member to SRW Scan Term.
1045 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1047 Fixed NMEM system to return aligned blocks on the smallest boundaries
1048 that are suitably aligned for all possible types on the particular
1049 architecture YAZ is being built for.
1051 --- 2.0.30 2005/01/04
1053 Fixed numerious warnings that was issued with newer versions of GCC.
1055 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1056 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1059 Make YAZ Generic Frontend Server slightly faster.
1061 Enhance (and reduce) logging for Generic Frontend Server.
1063 Revert YAZ log system so that it flushes every write operation
1064 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1066 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1067 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1068 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1069 will effectively disable old definitions.
1071 --- 2.0.28 2004/11/09
1073 Added yaz_log_time_format which specifies log format using
1076 Added yaz_log_module_level which returns mask for a module. Value
1077 is non-zero mask a if module is enabled; zero if disabled.
1079 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1080 in include/yaz/cql.h.
1082 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1084 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1086 Fixed bug #172: RPM builds does not enable SSL.
1088 Doxyfile.in part of dist. Doxyfile generated by configure.
1090 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1091 are given and the corresponding component does not exist.
1093 Extend CCL documentation in YAZ reference. Describe r=r.
1095 --- 2.0.26 2004/10/01
1097 Fixed MARC->MARCXML conversion to properly deal with
1098 fields, subfields, indicators having non-ASCII characters.
1100 Fixed MARC->MARCXML conversion so that ASCII control characters
1101 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1104 Added YAZ GFS support for conversion from Z39.50 surrogate
1105 diagnostics to SRW surrogate diagnostics.
1107 Bug fix: YAZ GFS did not return schema in explainResponse.
1109 --- 2.0.25 2004/09/30
1111 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1112 now converts recordSchema to elementSetName as well as schema URI.
1114 Fixed bug in COMSTACK that prevented HTTP request packages from being
1117 --- 2.0.24 2004/09/29
1119 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1120 does not require white-space before and after the dash in a range, e.g.
1121 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1124 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1125 due to new GCC removing "redundant" code.
1127 Added yaz-client commands scanpos and scanstep that sets preferred
1128 position and step-size for scan.
1130 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1132 Added CCL utility ccl_qual_buf which parses one or more CCL
1133 spec lines in a buffer.
1135 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1136 of name and value - ignoring empty lines and comments.
1138 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1140 Added odr_get_element_path which returns current element path for an
1141 ODR handle. This utility is useful in error handling or user-defined
1144 Added ODR_PRINT utility odr_set_stream which is is a more generic
1145 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1146 to a write function and pointer to close function. The close function - if
1147 non-NULL - will be called during odr_destroy.
1149 Fixed bug in CCL parser where truncation char was not removed from
1150 right side when truncation=both was in effect.
1152 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1155 --- 2.0.23 2004/08/11
1157 Fix buffer overrun in CQL parser when dealing with proximity (%).
1159 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1160 to UTF-8/UCS conversion is now only based on codetables.xml.
1162 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1164 --- 2.0.22 2004/08/06
1166 Add support for more "commit changes" in ZOOM (uses Extended Services).
1168 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1171 Yet another small fix for configure of SSL.
1173 --- 2.0.21 2004/05/14
1175 Fix SSL libs for configure when --with-openssl=DIR is given.
1177 --- 2.0.20 2004/05/10
1179 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1181 SSL comstack now uses yaz.pem certificate file on server side
1182 by default. Certificate filename can be configured by calling
1183 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1185 Fix bug regarding multiple calls to ZOOM_connection_connect.
1187 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1189 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1190 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1192 ZOOM now allows inspection of X509 peer certificate for verification.
1193 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1195 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1196 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1197 as "modular" but it simplifies things.
1199 Added cs_get_peer_certificate to that returns peer X509 PEM.
1201 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1202 NULL if SSL is unavailable.
1204 Documentation about MARC decoding tools.
1206 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1208 --- 2.0.19 2004/03/30
1210 Rename CHANGELOG to NEWS to follow GNU style packing.
1212 Fix bug with missing initialization of member in init_diagnostics.
1213 This bug affects threaded version of GFS server.
1215 --- 2.0.18 2004/03/20
1217 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1220 Ensure zlib.dll is packed with Windows install.
1222 --- 2.0.17 2004/03/17
1224 Fix encoding of xsd:string to use text instead of CDATA.
1226 Fix endless loop in CQL parser with unbalanced ".
1228 Use a more compact way to store MARC-8 conversion tables.
1230 --- 2.0.16 2004/03/16 Debian only
1232 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1235 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1240 --- 2.0.15 2004/03/01
1242 Another fix for decoding of XML packed records.
1244 --- 2.0.14 2004/02/25
1246 Fixes for Chunked encoding. White space not ignored after length spec.
1248 Update NS and use default NS for SRW diagnostic elements.
1250 --- 2.0.13 2004/02/23
1252 Implement ZOOM_resultset_cache_reset which resets record cache.
1254 Implement ZOOM_resultset_sort which sorts a result set.
1256 Implement chunked HTTP transfer.
1258 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1260 --- 2.0.12 2004/02/16
1262 Added member 'schema' to bend_explain_rr structure so that backend
1263 can specify explain record identifier. Defaults to Zeerex 2.0.
1265 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1267 --- 2.0.11 2004/02/16
1269 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1272 Added init command for yaz-client which sends "extra" init request.
1274 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1275 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1277 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1279 Make ZOOM error code for "invalid query".
1281 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1283 --- 2.0.10 2004/02/05
1285 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1288 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1290 Added option -p <file> to make Generic Frontend Server to write PID file.
1292 Added option -D to put Generic Frontend Server in background on its own.
1294 Make ZOOM C recognize option "password". If unset, "pass" is used
1295 (for backwards compatibility).
1297 Fixed a bug in Generic Frontend Server that could make it crash if a
1298 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1301 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1302 Must be issued before open, in order to be in effect.
1304 --- 2.0.9-6 2004/01/12 Debian/Windows
1306 Make the SRU server more picky WRT unknown params, etc.
1308 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1310 New YAZ client command, options, that sets Z39.50 options.
1312 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1313 options from a string of tokens (one token for each option bit).
1315 Update SRW diagnostic code messages.
1317 --- 2.0.9-5 2004/01/07 Debian/Windows
1319 Handle user defined stylesheet for SRW/SRU.
1321 --- 2.0.9-4 2004/01/06 Debian/Windows
1323 Fix bug in decoding of Content-Length.
1325 --- 2.0.9-3 2004/01/06 Debian/Windows
1327 Fix a bug with decoding of XML packed records.
1329 --- 2.0.9-2 2004/01/05 Debian only
1331 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1333 Fix bug in SRW/SRU diagnostics decoding.
1335 --- 2.0.9 2004/01/05
1337 Fixed bug in Generic Frontend Server which could drop records exceeding
1338 preferred message size. Reported and fixed by Irina Dijour.
1340 Fixed calculation of package size for structured records in Generic
1341 Frontend Server. Reported and fixed by Irina Dijour.
1343 Fixed namespace for SRW/SRU diagnostics.
1345 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1347 --- 2.0.8 2003/12/22
1349 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1350 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1353 CQL changes to reflect recent changes to the specification:
1354 * Documentation talks about context sets instead of index sets.
1355 * Documentation talks about indexes instead of qualifiers.
1356 * The CQL-to-PQF transformer's configuration file now uses
1357 "index.set.name = <attributes>" instead of the old form
1358 "qualifier.set.name = <attributes>". (Both forms are still
1359 understood but the latter is deprecated.)
1360 * CQL terms with no explicit index specified are now interpreted as
1361 cql.serverChoice instead of srw.serverChoice (which of course
1362 behaves exactly the same.)
1364 --- 2.0.7 2003/12/16
1366 MARC conversion can now generate ISO2709 output in another
1367 character set. yaz-marcdump uses this facility if you invoke it
1370 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1371 functions from there can be used from C++.
1373 --- 2.0.6 2003/12/04
1375 Frontend server now transfers memory from decoded packages to stream
1378 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1379 references to show up.
1381 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1382 the ZOOM Abstract API. The older names for the same options are still
1383 also supported for the benefit of old applications.
1385 ZOOM-C supports "implementationId" and "implementationVersion" options
1386 to go along with "implementationName". These allow the user code to
1387 specify identification strings to be sent to servers.
1388 Add OID for the new ExtLite attribute set.
1390 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1391 as requested/supplid by Ere Maijala <ere@atp.fi>
1393 For generic frontend server, reverse the order of
1394 "toolkit-supplied / application-supplied" strings sent as implementationId,
1395 Name and Version. Also, remove the spaces around the slash. This brings
1396 the GFS in line with the behaviour of ZOOM-C on the client side.
1398 Add function ZOOM_scanset_display_term.
1400 yaz-client shows scan displayTerm if present.
1402 Utility yaz-iconv is now installed by default along with the man page
1405 Extend configure check for OpenSSL to use pkg-config where available (such
1408 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1409 server to specify uid/gid/mask for socket using the format
1410 unix:[user=uid,][group=gid,][umask=mask,]file=path
1411 If file= is omitted the existing format is assumed, e.g.
1413 in which case the mask is 0666 (rw for everybody).
1415 Major restructure of YAZ source. All source in libyaz is in src directory.
1416 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1417 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1419 Added man page for utility yaz-marcdump (used to be called marcdump).
1420 yaz-marcdump is installed by 'make install'.
1422 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1423 of incoming package failed.
1425 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1427 Change prototype of odr_perror: add const to message string.
1429 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1431 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1432 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1433 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1434 DNS lookup. There should not be any compatibility problems with this
1435 assuming that blocking=1 or 0 is used.
1437 Fix bad reference in UNIX comstack in function cs_addrstr.
1439 Fix for compilation on AIX.
1441 The generic front-end server (server/seshigh.c) now supports returning
1442 Init diagnostics to the client in User-information-field, in
1443 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1446 --- 2.0.4 2003/09/04
1448 Allow any CQL relation (not just all,any,exact,scr).
1450 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1451 that features the same UI.
1453 Implemented command update0 in YAZ client which is equivalent to
1454 update but uses old of Ext Update ASN.1.
1456 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1457 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1458 Previously no OID was used for this info.
1460 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1461 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1462 returns 'malformed search term' otherwise.
1464 SortResponse member resultCount now set to NULL in sort handler of
1467 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1470 Add three new utility functions for translating OIDs between various
1471 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1472 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1473 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1474 char *oid_to_dotstring(const int *oid, char *oidbuf);
1475 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1477 Reverted modifications for ES Update definition for z_IU0Update
1478 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1479 is back to YAZ 2.0.2.
1481 String value attributes for CCL parser.
1483 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1484 which their FirstSearch server returns in Init responses, sometimes
1485 carrying useful diagnostic information when Init fails. This has the
1486 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1487 "z39.50/oclcui.asn", where its definition is somewhat different from
1488 what OCLC document on their web-site, as required to interoperate with
1491 Support for anonymous authentication in yaz-client. Use the command
1494 * Fix the OID of the Index Data-local "admin" Extended Service from
1495 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1496 the 1000, which indicates a locally-defined OID, was a mistake.
1498 --- 2.0.3 2003/06/20
1500 Fix CCL directive @case handling so that it affects string match for
1501 both CCL keywords and qualifiers.
1503 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1504 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1505 Decoder has been updated with ASN.1 changes as listed in
1506 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1507 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1508 z_IUUpdate, remains unchanged.
1510 ZOOM_record_get may now return a record in a specific character set.
1511 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1512 "from" is the character set of record as returned by target. "to" is
1513 the character set to be returned. If omitted, "to" is UTF-8.
1515 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1517 New ODR utility, odr_getelement, which returns name of element for
1518 which encoding/decoding failed.
1520 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1521 in cases where a required element was omitted.
1523 Bug fix: some MARC8 sequences were not converted.
1525 New ZOOM option "step" which specifies number of records to be
1526 retrieved in one chunk. Used in conjunction with "start" and "count".
1528 SRW support for yaz-client. Use scheme http: to use it, e.g.
1531 yaz-client no longer does (un)intelligent character set conversions
1532 by default. Can be enabled with charset and marc_charset commands.
1534 xmalloc trace fix for 64-bit systems such as DEC alpha.
1536 Solaris 2.6 compile fix.
1538 New function, cql_strerror() translates SRW error codes, as returned
1539 by cql_transform_error(), into human-readable English strings. Used
1540 in yaz-client diagnostics when appropriate.
1542 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1543 converts it into a type-1 query which is sent to the server. This
1544 makes CQL available for use with all Z-servers, as opposed to the tiny
1545 minority that can handle CQL queries themselves.
1547 --- 2.0.2 2003/04/28
1549 New Debian package layout similar to the Redhat Package layout.
1551 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1552 and search result respectively.
1554 --- 2.0.1 2003/04/25
1556 Redhat package is now several packages: libyaz (runtime libraries),
1557 libyaz-devel (development and documentation, and yaz (utility programs).
1558 Package spec file by Morten Bogeskov.
1560 New member 'schema' in struct bend_fetch_rr which the name of requested
1561 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1562 handler MAY set this to reflect the schema of the returned record.
1564 New member 'display_term' in struct scan_entry. GFS now sets member entries
1565 and allocates scan entries to be filled by user scan handler. In previous
1566 version, entries member was allocated by the scan handler. That still works,
1567 but the GFS will ignore member display_term - assuming it was NOT set by
1568 the handler. The fact that the GFS now allocates the entries both allows
1569 for new members and makes a scan handler easier to write.
1571 Fix CQL lex buffer overflow.
1573 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1574 SRU default recordPacking is string.
1576 SRU protocol support for frontend server.
1578 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1580 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1582 Added scan for the ZOOM shell (zoomsh).
1586 * String Identifers for Schemas (Amendment 5).
1587 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1588 Old definition for schema
1589 Odr_oid *schema; /* OPT */
1594 Z_InternationalString *uri;
1595 #define Z_Schema_oid 1
1596 #define Z_Schema_uri 2
1599 * resultCount parameter to Sort Response (Amendment 1).
1600 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1602 Support for SRW 1.0 over HTTP. This is an optional feature and
1603 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1606 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1607 on the same port. SRW SearchRetrieveRequests are mapped
1608 to bend_init,bend_search,bend_fetch,bend_close.
1610 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1612 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1613 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1615 ZOOM connections are SRW based if schem http is used for hostname
1616 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1617 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1619 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1620 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1621 distance=n, order=true/false, relation=le, prox unit=word. If
1622 n is omitted, distance 1 is used.
1624 Fixed problem with C compiler include path in wrong order.
1626 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1627 on Solaris. Patch from Ko van der Sloot.
1629 New MARC decode API. All new functions operate on a yaz_marc_t
1630 handle. The most important new functions are: yaz_marc_create,
1631 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1632 decode and destroy respectively. Decoder can produce formats
1633 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1634 include/yaz/marcdisp.h.
1636 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1637 to UTF-8, UCS-32, wchar_t or Latin-1.
1639 * Prototypes for yaz_iconv_-functions moved to separate header
1640 include/yaz/yaz-iconv.h.
1642 Make a few private functions 'static' in unix.c. This prevents
1643 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1645 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1646 are set when Init Response is received.
1648 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1649 but returns diagnostic set as well.
1651 New function yaz_strerror which is a portable wrapper for
1652 strerror/strerror_r/GetLastMessage.
1654 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1655 is returned for MARC. If type is "oai", then OAI MARC is returned.
1657 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1660 --- 1.9.2 2002/11/26
1662 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1664 Fix bad race conditions on SIGTERM and terminate gracefully in
1667 Move retrieval (data1) module to Zebra since nobody seems to be
1670 Add GRS-1 render for ZOOM using same format as yaz-client.
1672 --- 1.9.1 2002/10/05
1674 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1676 Fix broken ESpec handling in data1 module.
1678 SGML reader parses comments and makes them part of the data1 tree.
1680 Added several type casts so that YAZ compiles as C++ code.
1682 ZOOM didn't handle PDU encoding failures properly.
1684 Added more Bib-1 diagnostics (approved extensions).
1686 GNU configure: better check for iconv.
1688 More portable use of accept, getpeername. Check for socklen_t. Use
1689 int/size_t if socklen_t is not defined.
1693 PQF parser rejects bad queries - including those with extra
1694 characters in them. PQF parser used to silently ignore that.
1695 Cleaner API for PQF added, which allows you to get detailed
1696 error information for bad queries (see yaz/pquery.h).
1698 Fixed bug in ZOOM_record_get for type "database".
1700 Implemented mini iconv library supporting conversions between
1701 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1703 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1705 --- 1.8.9 2002/08/20
1707 Fixed ZOOM C record cache so that preferredRecordSyntax and
1708 elementSetName is used to check for already fetched records.
1710 --- 1.8.8 2002/08/02
1712 Added three members in bend_initrequest structure to facilitate
1713 character set negotiation.
1715 Fixed a bug in frontend server that could cause indefinite
1716 loops under rare conditions.
1718 Revised character set utilities (charneg.h) so that encoding
1719 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1721 For PQF, directive @term <type> sets term type for Scan/Search.
1722 Here <type> is general, string, numeric, null. The term type
1723 is inherited - just like @attr.
1725 New call odr_set_charset that sets character set conversion for
1726 international-strings on a ODR stream. Prototype is:
1727 int odr_set_charset(ODR o, const char *to, const char *from);
1728 The InternationalString is still represented as C string in YAZ
1729 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1730 won't). On the protocol level, you can use any encoding.
1732 Support for UNIX sockets in ZOOM.
1734 Solaris recv sometimes returns errno == ENOENT. It is treated as
1735 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1737 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1738 both client and server. Code by Morten Bogeskov.
1740 --- 1.8.7 2002/05/22
1742 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1743 that they can be used directly from Visual Basic. You must recompile
1744 your windows APP if you're using ZOOM.
1746 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1747 Commands "lang" and "charset" sets language and character set respectively.
1748 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1749 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1751 Attributes from multiple CCL fields may be OR'ed rather than merged
1752 using directive "@field or". Fields are still merged by default -
1753 equivalent to "@field merge".
1755 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1758 Fixed bug in zget for parameter ExtendedServicesResponse.
1762 --- 1.8.6 2002/03/25
1764 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1766 Client displays USR.1:SearchResult-1 (hits per term).
1768 Additional Search Info for search in Generic Frontend Server.
1770 Fixed CCL parsing of "field=s".
1772 WIN32 installer - using the excellent NSIS software from nullsoft.
1774 Fixed CCL parsing of "field = - <number>".
1776 Added function yaz_marc_decode that decodes MARC for line mode
1777 display or XML (similar to that used by JZKit).
1779 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1780 Z39.50. But ISO/ILL was, however.
1782 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1783 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1785 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1786 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1788 --- 1.8.5 2002/02/03
1790 New YAZ client features: Command completion and new commands:
1791 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1792 Code provided by Jacob Poulsen.
1794 New call oid_trav, that visits all registered OIDs via callback.
1796 Function ZOOM_record_get now returns const char pointer rather than
1797 void pointer. It saves a lot of type casts.
1799 For YAZ client, command "auth" now allows you to set authentication
1800 in IdPass style. It is enabled when three tokens are given - order
1801 is user, group and password.
1803 Fix memory leaks in MARC record handling for ZOOM.
1805 New option for YAZ client, -k <kilobytes> that sets
1806 maximum record size. Similar to -k option for generic frontend
1807 server and yaz-ztest.
1809 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1811 Prefix query parser reports "fail" when bad attribute set is given.
1813 Fix in MARC decoder. Proximity logging. Fix for attribute set
1814 in scan handler for server. Patches by Shigeru Ishida.
1816 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1819 Configure option --with-openssl=<dir> now works when a directory is
1820 specified. Patch provided by Morten Bogeskov.
1822 New option for YAZ client, -u <auth>, that sets authentication.
1824 ZOOM fix: error information was sometimes "missing", since error
1825 was cleared/reset too when it shouldn't.
1827 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1829 --- 1.8.4 2002/01/04
1831 Scan for ZOOM API. New object ZOOM_scanset. New functions
1832 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1833 ZOOM_scanset_destroy.
1835 New ZOOM function, ZOOM_connection_last_event, that returns type
1836 of last event (such as "receive data", "send data", "apdu received",
1839 New ZOOM option, schema, that specifies schema for retrieval.
1841 New CCL feature. Qualifiers can be aliases for one or more
1842 other qualifiers (if more than one is given, OR is used).
1844 ZOOM uses named result sets if target supports it.
1846 Two new YAZ client commands: . (dot, which sources a script of YAZ
1847 client commands), and ! (to execute shell command.). Implemented
1850 Working on Debian packages.
1852 --- 1.8.3 2001/11/19
1854 YAZ client enables named result sets only if target supports it.
1856 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1858 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1859 with key="host" to get same result.
1861 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1862 Function Z3950_resultset_record(s) returns references to records
1863 "owned" by resultset. To become owner use Z3950_record_clone.
1865 Function z_ext_record handles Extended Services. Thanks to
1868 --- 1.8.2 2001/11/12
1870 CCL Parser fix: ignore token comma when dealing with and-lists.
1872 Documentation updates for COMSTACK.
1874 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1875 Changed prototype Z3950_records. For some functions, int parameters
1876 were changed to size_t.
1878 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1881 New MARC decode/display function, marc_display_exl, which properly rejects
1882 non-ISO2709 records. YAZ client uses it.
1884 --- 1.8.1 2001/10/29
1886 Fix bug: local attribute set wasn't set correctly in PQF strings.
1890 * Old Z39.50 codecs no longer supported.
1892 Added ZOOM C binding. See http://zoom.z3950.org/
1894 Renamed states for COMSTACKs to avoid confusion with events.
1896 Implemented cs_look and proper cs_rcvconnect.
1898 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1900 Configure detects POSIX threads on OpenBSD.
1902 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1903 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1905 When error is returned from present handler, non-surrogate diagnostic
1906 is returned in present response (and fetch handler is no longer called).
1908 * Minor adjustments to pquery parser (PQF). Token characters may be
1909 escaped by using backslash (C-style).
1911 PQF parser allows string attribute values to be specified. For @attr,
1912 non-numeric characters after the equal-sign are treated as strings
1913 (e.g. @attr 9=title).
1915 CCL trunction character may be defined (@truncation in file)
1917 * function zget_ExtendedServicesRequest sets waitAction to
1918 waitIfPossible (was wait).
1920 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1923 CCL operator names may be set in field definition files (CCL_bibset).
1924 See ccl/bib1 for an example.
1926 Fixes in ASN.1 compiler for C++ compatibility.
1928 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1929 and "op_or" to avoid conflict with C++.
1931 Fixed problem with GNU readline detection on Redhat 7.0.
1933 Added step-size for Scan backend handler.
1935 Fixed bug that made the frontend server crash when no attribute
1936 set was specified for scan.
1938 Front-end server automatically switches to original working directory
1939 when installed as an NT service. Previously -w had to be specified to
1942 Added extended attributes for retrieval module (data1), so that data1
1943 records carry d1_readXML/SGML attributes. d1_read also supports
1944 null-data rules ( <tag/>)
1946 On UNIX when POSIX threads are available, a separate library libyazthread
1947 is created. Programmers should link with that library and the yaz library
1948 when using threads. The reason for the split was that some applications
1949 on Linux, such as Apache, doesn't work well when using shared objects that
1952 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1953 (or any frontend server) in SSL mode by specifying ssl: followed by
1954 address. Only tested on UNIX.
1956 Added feature for CCL module. Virtual structure s=al or s=ol generates
1957 and-list and or-list respectively instead of phrase search.
1961 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1962 log_mask_str. This was done to avoid name conflicts with other libraries
1963 (such as other PHP extensions).
1965 Added raw OID member for preferred record syntax (request_format_raw)
1966 and returned record syntax (output_format_raw) for backend fetch method.
1968 Config file yaz-config now accepts options so that it returns specific
1969 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1971 Shared library support for UNIX using GNU libtool.
1973 * Modified backend interface. Request/Response struct's replaced by
1974 one read/write C struct. For example bend_fetchrequest and
1975 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1976 Every handler - even search has to be registered in bend_init
1977 handler. This means that the YAZ library no longer refers to
1978 external functions and it makes it possible to make the whole
1979 thing a single DLL/SO.
1981 Added Segment handler for backend server.
1983 Added Zmbol/Zebra administrative functions to YAZ client.
1985 Threaded frontend server on UNIX (when POSIX Threads are available).
1986 Starting the server with option -T enables multi-threading.
1990 Added configure option --enable-comp/disable-comp to control use
1991 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1992 located in sub directory asn.
1994 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1995 in ${exec_prefix}/bin along with the other programs yaz-client and
1998 GNU automake used to maintain makefiles.
2000 Added several OID's.
2002 Changed retrieval module so that we can load records with no abstract
2003 syntax defined. Tagpaths in these records are fully composed of string
2006 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2010 On UNIX, the generated makefile now supports a proper 'make install'.
2011 The prefix can be set via GNU configure to set the install location
2012 (default is /usr/local).
2014 * YAZ programs client and ztest were renamed to yaz-client and
2015 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2016 locations, such as /usr/bin,/usr/local/bin,etc.
2018 * YAZ Header files were moved from include to include/yaz. YAZ Header
2019 files are referred to as include <yaz/log.h> rather than <log.h>.
2020 The YAZ include path (-I ..) is therefore the same as before. Programmers
2021 should update their #include statements or use -Ipath/include/yaz
2022 instead. The main motivation for doing this change is that YAZ header files
2023 can be installed in "standard" locations /usr/include,/usr/local/include
2024 without introducing conflicts, since ALL YAZ header files are stored
2025 in subdirectory yaz (under /usr/include for example).
2027 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2028 rather than project/workspace files. We switched because project files
2029 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2032 Changed name of logging function, logf, to yaz_log, to prevent name
2033 clash with some math-log functions. The YAZ header log.h defines logf
2034 to yaz_log (#define) so there should be no incompatibilities by this
2037 Added bend_start/bend_stop handlers for server. These handler are
2038 called on start/stop of server. For windows they are called whenever
2039 a service is started/stopped.
2041 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2042 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2043 in util/yc.tcl. The auto-generated C code structures are, in a few
2044 cases, incompatible with the old decoders. There are differences in the
2045 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2046 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2047 The preprocessor variable ASN_COMPILED is defined when the compiled
2048 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2049 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2050 wish to use the old encoders/decoders you can specify --disable-yc
2053 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2054 version so that it supports both new - and old version of DB Update
2056 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2057 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2058 change. The name parameter can be set to 0 in which no name is specified
2059 for the construction. The macros odr_implicit and odr_explicit sets name
2060 parameter to zero for the construction involved. New macros
2061 odr_implicit_tag and odr_explicit_tag are similar to the others,
2062 except that a name parameter is added. For programmers' that don't use
2063 ODR they probably only need to change the call to z_APDU and z_External.
2065 Added access control facility by interfacing the TCP wrapper library.
2066 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2067 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2068 name of the daemon and enables the access control as specified in
2069 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2071 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2072 den Dool <H.M.vdnDool@kub.nl>.
2074 Added reference ID parameter to most functions in server API - refer
2075 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2077 Changed name of ccl library to libccl.a (was ccl.a).
2079 Fixed bug in decoder for Explain (Category TargetInfo).
2081 Added support for GNU readline in client. Thanks to Jacob Poulsen
2082 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2084 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2085 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2086 IMPLEMENTATION! This change was made to the development version before
2087 the ZIG decided to retract the amendment. If any users MUST be
2088 compatible with the original Update definition, PLEASE CONTACT US, and
2089 we will include a separate definition corresponding to the old Update
2090 ES. Note that because of the change to the ASN.1 of the
2091 TaskPackageRecordStructure we cannot define a single structure that
2092 will support both versions.
2094 * Added const modifier to buffer parameter for some ODR/BER encoding
2095 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2096 completeWAIS, odr_dumpBER.
2098 Fixed bug in client.c which caused a crash when a scanResponse didn't
2099 contain positionOfTerm.
2101 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2102 * will cause an error in a client if a non-YAZ target sends both a
2103 * list of Scan entries and non-surrogate diagnostics.
2105 Retrieval module enhancements. Tag sets may be typed in the reference
2106 to it. From the .abs-file the "tagset" directive takes a third optional
2107 integer type for the tag set referenced. From a .tag-file the "include"
2108 directive takes a third optional type as well. The old "type" directive
2109 in the tag set itself is still recognized but acts as the default type
2112 Backend interface change. Individual Scan terms returned from bend_scan
2113 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2114 in include/backend.h.
2116 Retrieval module enhancements. Multiple tag sets and attribute sets may
2117 be specified in abstract syntax specs. Revised the error/warning for
2118 logging messages reported by the retrieval module when reading the
2121 Object Identifier system (oid_..) changed. The API is backwards
2122 compatible but the oid-routines now allocates new OID's when needed.
2123 Raw OID's may be specified in oid_getvalbyname.
2125 YAZ now uses GNU configure to generate Makefile(s).
2127 * Minor changes in some of the member names of DeleteResultSetRequest and
2128 DeleteResultSetResponse. See include/proto.h.
2130 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2131 and added member 'languages' in TargetInfo (which was missing).
2133 Changed the way attribute sets are handled in the retrieval
2134 module. These are now cached, just like the abstract syntaxes
2137 Changed YAZ so that it links with compiled ASN.1.
2139 Added Explain-schema definitions and mapping routines. The following
2140 Explain categories have been implemented: AttributeDetails,
2141 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2143 Fixed minor bug in Windows version of Server Library.
2145 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2147 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2149 Added EXTERNAL: UNIverse Resource Report (non-standard).
2151 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2152 ENUMERATED and SET OF.
2154 * Added 'const' to some of the char pointer arguments for the
2155 functions, data1_read_node, data1_getelementbytagname,
2156 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2159 Fixed bug in data1_insert_taggeddata - the last_child member of
2160 parent wasn't initialised.
2162 * Changed data1_read_record and data1_read_node so that the supplied
2163 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2164 doesn't refer to any parts of the "SGML"-buffer.
2166 Fixed bug in server library (Windows version of statserv_remove).
2168 * Changed code so that it compiles as C++. The type definition
2169 of Odr_fun which is a member of Odr_arm was changed. The result is,
2170 that an explicit typecast is needed for the fun pointer when
2171 using Odr_arm - as in:
2172 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2174 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2176 Implemented the new structured date and time definition as approved
2177 by the ZIG. Added schemaId element to the specificTag in Espec-1
2178 (also approved at the last ZIG). Thanks to RVDM.
2180 Added some Object identifiers (RVDM).
2182 Changed the Update Extended Service (RVDM).
2184 Added command "refid" to client which specifies referenceId for
2185 the following requests.
2187 Implemented extended service handling for server. See ztest.c
2188 for an example as well as backend.h. New handlers are registerd
2189 in the Init handler.
2191 * Changed interface for sort in server.
2193 Added new members to statserv_options_block. It allows a server
2194 to read options from another source than just the command line. Thanks
2195 to Charles Woodfield.
2197 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2198 renamed to zboolean. Some C++ compilers complained about the name.
2200 Minor changes to gils.abs. Added index 's' (sort) on title
2201 and date/time-last-modified.
2203 --- 1.4pl2 1998/1/30
2205 Fixed bug in server library regarding inetd mode (-i). This bug
2206 was introduced by release 1.4.
2208 --- 1.4pl1 1998/1/29
2210 Added sort facility in client and backend server interface.
2212 Fixed problem with dependencies in Makefile(s).
2214 Fixed bugs for encoders/decoders of extended services and
2217 Implemented sub-tree feature for schemas. Sub-trees are
2218 referenced in *.abs-files. See explain.abs for an example
2219 of the use of this feature.
2221 Modified bib1.att; local attributes for ANY didn't include
2222 ANY itself (only affects use of the retrieval module).
2224 Fixed bug in plain SGML reader in function data1_read_node:
2225 tags with prefix "var" was incorrectly interpreted as variants.
2227 Added feature "sub-schemas" to enable references to - and definitions
2228 of - group of elements.
2230 * Removed member parent from type data1_element (in data1.h).
2232 Implemented function odr_nullval() that returns the value of
2235 * Removed member num_children from data1_node (in data1.h).
2237 Made NT service interface part of the server library. The
2238 function statserv_main uses the NT service when required and
2239 calls the statserv_start / statserv_close routines.
2241 Routine zget_SearchRequest and zget_PresentRequest fills
2242 resultSetName/Id member with "default" instead of "Default".
2244 Fixed memory leak in server. Request queue member wasn't freed.
2246 Fixed nmem_exit so that memory is freed.
2250 Revised the CCL parser utility to be thread safe.
2252 Added function, oid_ent_to_oid, to replace the function
2253 oid_getoidbyent, which is not thread safe.
2255 * Added nmem_init and nmem_exit to initialize and release
2256 NMEM resources. Function nmem_init should be called once in the
2257 initial thread before NMEM/ODR is used. statserv.c and client.c
2258 have been changed accordingly. The change was necessary to make
2259 NMEM thread safe. The NMEM memory pool is shared amongst threads
2260 in a process. Unix-based applications will still work fine without
2263 Added NT Services interface for the the Z39.50 (statserv) Server.
2264 Refer to the ztest.c source on the usage.
2266 Windows 95/NT port using MSVC5.0. Project files are included in the
2269 * Defined new 'global' handle for the retrieval (data1) system. The
2270 new handled, data1_handle, describes the state of the data1 system.
2271 This handle is passed as first argument to virtually all
2272 data1 related routines. The functions data1_create and data1_destroy
2273 creates and destroys a data1 handle respectively.
2275 Added ODR encode stream member to all backend request structures
2276 init, search, scan etc. This stream should be used to allocate all
2277 memory used for the response when thread safe operation is needed.
2279 Changed the comstack utility, cs_addstr, to be thread safe. The
2280 returned hostname string returned by the function is now part the
2283 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2284 function. The cs_straddr takes a COMSTACK handle as argument, so this
2285 function must be used after cs_create and before bind/connect.
2286 This function is thread safe.
2288 Moved test server to 'ztest' directory - generic server code still
2289 in 'server' directory.
2291 Made prefix query (pquery.c) utility thread safe.
2293 Added new function modifier YAZ_EXPORT to 'export' public DLL
2294 functions when using windows (see include/yconfig.h).
2296 Added definitions to the OID database (util/oid.c) (RVDM).
2298 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2300 Added call to ccl_rpn_delete in client program.
2302 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2303 release of RPN structure.
2305 Added support for C++, headers uses extern "C" for public definitions.
2306 With input from RVDM.
2308 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2309 Thanks to Ronald van der Meer (RVDM).
2311 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2313 Added support for private extensions to the OID database
2314 (oid_setprivateoids()). Thanks to RVDM.
2316 Added optional, physical ANY (key replication)
2318 Fixed null-reference problem in GRS-1 output filter.
2320 Proximity operator added to Prefix Query Format (PQF).
2322 In test client command "base" accepts multiple databases.
2324 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2328 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2330 Smallish bug-fixes in the new encoders/decoders (explain).
2332 Bug fixed in DeleteRequest.
2334 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2336 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2338 Added SOIF syntax (using private OID for now) to retrieval module and client.
2340 Added Update extended service.
2342 Added SearchResult-1 additional info structure.
2344 Added optional CCL (ISO8777) interpreter as separate module. Available
2347 --- 1.2 1996/6/10 (1st anniversary release)
2349 Added Summary record syntax. Lightly tested.
2351 Added OPAC record syntax. Untested.
2353 Added ResourceReport service encoders/decoders. Untested.
2355 Fixed bug in z_Unit - wrong tagging on unitSystem.
2357 Fixed bug in the DiagRecs decoder.
2359 Added options for max PDU size and session timeout to frontend-server.
2361 Added documentation of query-language parsers and other supporting utilities.
2363 [frontend-server] Added Attribute set to the bend_scanrequest API.
2365 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2366 surrogate diagnostics were generated.
2368 [retrieval] Allow multiple local values for attribute.
2370 [retrieval] Allow multiple attributes per element in .abs files. index type.
2372 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2374 --- 1.1pl2 1996/4/10
2376 Minor changes, mostly specific to Zebra's requirements (retrieval)
2380 Repaired bug in frontend server when running multiple listening
2381 endpoints in dynamic mode.
2383 z_External() now won't break if a known, ASN.1 value comes encapsulated
2384 in an octet-string. The value will pass through unmodified in an Odr_oct.
2386 Added a bit of code to the demo client to decode & display
2387 ASN.1-structured records represented in the octet-aligned branch of
2388 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2390 Added z_ext_getentbyref() to the ASN module. Doc updated.
2392 * Completed the SCAN definition in the ASN module. This may break SCAN
2393 code based on older YAZ-versions at compile-time. The fix is easy -
2396 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2397 under the SCAN definition. Remember to initialize this, server-people.
2399 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2400 that this does not extend to ODR and ASN.
2402 Comstack allows insertion of established socket (primarily for
2403 inetd-operation of servers). Doc updated.
2405 Front-end server can now start from the inetd in TCP mode. Doc
2408 --- 1.0pl4 1996/1/24
2412 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2413 the rank and record number.
2415 Adjustments to the frontend server.
2417 Fixed diagnostic BER dumper. It ignored the file argument.
2421 Various changes to retrieval module.
2423 Changed the union discriminators of the protocol files from enums to
2424 ints paired with #defines.
2426 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2429 *Changed operator in the RPN structure to 'roperator', again to avoid a
2432 Fixed problems in Explain decoders/encoders.
2434 --- 1.0pl2 1995/12/6
2436 Memory bug in log module fixed.
2438 --- 1.0pl1 1995/12/5
2440 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2442 Bug in Explain DatabaseInfo module fixed.
2444 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2448 The shift to v1.0 signals that we now consider the *core* functionality
2449 of YAZ reasonably stable (the core being more or less equivalent to
2450 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2451 tested (Explain not at all - though that will happen soonish).
2453 Minor changes to code to support Windows port.
2455 Various minor changes after we're getting to use GRS-1 & co. more.
2457 Added Espec-1 format.
2459 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2460 of the protocol and it cannot be selected when encoding (maps into 'string'
2461 when decoding). Needed to talk to some servers.
2463 Demo client can request simple element set names.
2465 Added Diagnostic Format encoders/decoders.
2467 Added simple Close handling to frontend server (no hooks for resource
2468 reporting yet), and demonstration client.
2470 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2472 --- 1.0b3 1995/08/24
2474 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2475 handled incorrectly when records were requested in the searchResponse. This
2476 will only affect you if you use the frontend-server.
2478 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2479 Test-client will ask for and print GRS1. Ztest will return dummy records
2482 Added Explain encoders/decoders to the service-level API. Untested.
2484 Added Extended Services: Item Order encoders and decoders to the Service-
2485 level API. Untested. We could use a recent copy of the pertinent bits
2486 of the ILL protocol to add those bits.
2488 Added diagnostic format 1 encoders/decoders to the service-level API.
2491 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2492 odr_cons.c, which causes a more correct output.
2494 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2495 was always set to 0 when no records were requested in the searchRequest.
2497 * Added better external-handling. This shouldn't harm old code that
2498 *encodes* externals. It can break code that looks for a
2499 'single-ASN1-type' representation, since those types that are known
2500 are now decoded immediately. Look at the SUTRS sample code in
2501 seshigh.c and client.c. Documentation updated.
2503 Handling of structured records in bend_fetchresponse. Length -1 marks
2504 structured record, type is deduced from format field.
2506 --- 1.0b2 1995/06/27
2507 Fairly quick maintenance release to add SUTRS support.
2509 Fixed handling of SUTRS records in the demonstration client.
2511 * Added format field to the bend_fetchrequest and bend_fetchresponce
2512 structures of the backend API (frontend server). When the record is
2513 returned, the value of the format field is mapped to an OID. The
2514 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2515 of the record. The special value VAL_NONE in the bend_request means
2516 that no specific format was requested by the client. Documentation
2517 updated accordingly. Test server (ztest) will return a fixed dummy
2518 SUTRS record if your client requests SUTRS.
2520 Documentation updated accordingly.
2522 You can now set external libraries and RANLIB support in the top-level
2526 First public release.
