1 For configure, using option --without-xml2 also disables Libxslt/Libexslt
4 Added support for ISO5426 to UTF-8 conversion.
6 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
7 implementation version.
9 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
13 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
14 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
16 ZOOM C now interprets databaseName option for ZOOM connection as path
19 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
21 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
23 Dummy Libxml2 types no longer defined in headers of YAZ'.
25 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
30 Various ODR chapter fixes.
32 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
34 Added missing source for Windows compilation, mutex.c.
36 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
38 For SRU connections in ZOOM all records up to "count" are now fetched.
40 Fixed crash in generic frontend server (and yaz-ztest) which occurred
41 in Windows due to bad error handling for Libxml2.
43 Added facility for sending arbitrary records (ASN.1 any) using
44 ZOOM C's Extended service update. Patch by Sam Reynolds.
46 New options for ZOOM C's connection, logapdu which makes ZOOM log
51 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
55 Fixed memory violation that could occur when decoding UTF-8. This bug
56 was only present in 3.0.30 of YAZ.
60 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
61 GNU TLS is used by default (if found).
63 yaz-ztest returns OPAC records if a client asks for OPAC.
65 Improved speed of MARC-8 encoding.
67 Added support for lossy and loss-less MARC-8 encoding.
69 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
71 Added new Windows Service wrapper (sc).
73 yaz-client's itemorder command may now send a file.
75 Fixed yaz-marcdump to allow the use of NS prefix for record element.
77 Added new function yaz_log_xml_errors.
79 Allow (but warn) unknown XML attributes in MARCXML parsing.
81 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
83 The UTF-8 to MARC-8 conversion now uses a different set of characters
84 for Greek symbols. Bug #2120.
88 Added yaz_daemon (daemon.h).
90 Fixed bug #2068: pkg-config trouble
92 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
96 Document --with-xml2 option.
98 Added OPAC XML XSD (etc/opacxml.xsd).
100 Allow glob mask for name attribute in retrieval element for the
101 generic frontend server's retrieval facility.
103 Changed yaz_poll_poll to return yaz_poll_except for all returned events
104 except POLLIN/POLLOUT.
106 Fixed error handling in cs_listen. Bug #2037.
108 --- 3.0.22 2008/01/20
110 Fixed version in yaz/yaz-version.h.
112 Fixed bug #2027: Crash when closing connection.
114 Changed configure so that ICU support is only enabled if only ICU
115 and Libxml2 is available (because the ICU chain is XML based).
117 --- 3.0.20 2008/01/15
119 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
120 is built. Only this DLL depends on the ICU runtime.
122 yaz-ziffy is no longer part of YAZ. It is distributed separately by
123 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
125 Changed license of CCL module to 'Revised BSD'. After consultation with
126 remaining members of the original EUROPAGATE consortium, we are re-issuing
127 the CCL module without a separate license. The software was developed by
128 Index Data as part of a research project. The special license was included
129 to help feed usage information back to the project consortium to support
130 project evaluation. At this time, the project consortium has long-since
131 disbanded, and the majority of the original principals have retired. At the
132 same time, we have significantly modified the software during the following
133 years, to the point where very practically no original code remains. To
134 simplify re-use of the software, we have contacted those members of the
135 consortium who could be reached, and agreed to re-issue the module as a
136 proper part of the YAZ package.
138 Tcl scripts uses /usr/bin/tclsh as preferred shell.
140 CQL closer to being version 1.2 compliant. CQL also allows free-form
141 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
144 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
145 bug could make Extended services handling crash in the ZOOM layer. This
146 bug was only present in YAZ 3.0.18.
148 --- 3.0.18 2007/12/19
150 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
153 yaz-marcdump reads and writes collection wrapped records.
155 Handle OPAC for record conversion module.
157 Fixes for ICU wrapper.
159 Allow ICU libs to be controlled with --with-icu .
161 --- 3.0.16 2007/11/12
163 Added yaz_poll which is a wrapper for select/poll. When poll is available
164 and non-buggy, it is used, by yaz_poll . This allows more than 1024
165 sockets to be in use.
167 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
168 functionality through an XML based configuration (ICU chain). This system
169 is useful for search facilities such as Pazpar2 and Zebra that needs to
170 perform tokenization of indexed material. The ICU code in a separate
171 library libyaz3_icu.a.
173 Added HTTP tunnel facility for COMSTACK, bug #1752.
174 This is a facility that allows a Web proxy, such as squid, to tunnel
175 Z39.50 traffic. This facility is "transparent" to must applications
176 using YAZ. It's enabled by using pseudo transport connect: followed by
177 the proxy address, followed by command, then follwed by he regular
178 "virtual" addresss. For example,
179 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
181 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
183 --- 3.0.14 2007/09/21
185 Fixed bad memory reference in ZOOM_record - cuased by member not being
186 initialized. This was a problem only in YAZ 3.0.12.
188 Fixed bug in conversion from MARC to XML: Non-XML characters in control
189 fields were not removed.
191 Changed the way C code is generated from codetables.xml. Made a MARC-8
192 conversion trie for each characterSet section rather than codeTable.
193 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
194 of codetables.xml from Larry Dixson, LOC. Bug #1464.
196 --- 3.0.12 2007/09/12
198 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
199 from ZOOM_record_error).
201 ZOOM C function ZOOM_record_get returns record schema for type="schema".
203 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
205 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
207 Better SRW-to-Bib-1 diagnostic mapping.
209 ZOOM C and yaz-client announces SRU version 1.2 by default.
211 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
214 Fixed in yaz_sru_decode to allow other version than 1.1.
216 --- 3.0.10 2007/08/22
218 Added support for SRU scan for ZOOM.
220 Added support for the use of the older versions or Extended Service
221 Update in ZOOM. To faciliate this, an option "updateVersion" may be
222 set to the version , 1=first, 2=second, 3=third. The third version is
223 what ZOOM C has used so far. And that, obviously, is the default.
225 Added support for CCL queries in Z39.50 queries sent to the GFS (and
226 therefore in Zebra and in SimpleServer-based applications). The new
227 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
228 qualifier file used to transform incoming CCL queries into Type-1 RPN,
229 which is passed into the back-end search callback function.
231 Added support for HTTP Basic authentication in clients: the SRU/W
232 codec encodes the username/password elements of the PDU structure
233 appropriately, and these may be set using the "user" and "password"
234 options in ZOOM-C applications (the same options that are used for
235 Z39.50 authentication).
239 Fixed bug #1208: SSL appears to be broken in ZOOM.
241 Fixed bug #1206: Libxml2 include path weirdness.
243 Added oid_name_to_dotstring.
245 Allow elementSetName to be specified for ZOOM C record update.
247 Allow waitAction to be specified for ZOOM C based for Extended Services.
249 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
250 syntax OID. Bug introduced in YAZ 3 series.
252 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
256 Fixed bug #1157: yaz-client does not read .yazclientrc from current
257 directory. yaz-client now reads commands from file given by option -f
258 if specified; then tries to read .yazclientrc in current directory.
259 Failing that, it reads .yazclientrc from user's home directory.
261 Added support for correlationInfo Note and ID for Record Update via
264 Added yaz-client command querycharset which specifies character set for
265 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
266 (termListAndStartPoint).
268 Charset ISO5428:1984 is an alias for ISO5428-1984.
270 Implemented a way to perform scan in a result set using Z39.50. This
271 is achieved by attaching the result set name in the characterInfo
272 (type InternationalString) of OtherInformation in the Scan Request PDU.
273 The result set is identified in the otherinformation by the new OID:
274 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
275 This allows for scan in result set and faceted search . Zebra did some
276 of this in the APT term using attribute type 8 and value being result
277 set. Using the OtherInformation approach for this is cleaner and easier
278 to work with in proxies and the like. This facility can be used in
279 yaz-client using new command setscan which takes a result set as first
280 argument, start position (APT) as second.
282 Changed decoding of SRU XML packed records to deal with servers that
283 have recordData with XML data with multiple root nodes. Also make
284 comparison for recordPacking case insensitive. Again, one server
285 returns "XML" where others return "xml".
287 For SRU responses allow Content-Type application/xml as well as text/xml.
291 Fixed bug in character set conversion of BER strings. Bug introduced
296 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
298 For OID class, use oid_class consistently.
300 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
303 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
304 character set for bibliographic information interchange". By Giannis Kosmas.
306 Added documentation on new OID API.
310 Changes to generic frontend server interface: added new member
311 'query_charset' for bend_initrequest structure. A backend init handler
312 should set this member to its native character set for query terms.
313 When defined, the frontend server logic will announce this character set
314 to a client if the negotiationModel bit is set by the client. All server
315 implementors are encouraged to specify this. If a backend server does not
316 specify this a warning is issued using yaz_log(YLOG_WARN,..).
318 Added CCL utility to remove terms (stop words) from resulting RPN
319 tree. This is handled by functions with prefix ccl_stop_words_ .
321 New ZOOM C option, "rpnCharset", which allows client-side conversion of
322 terms in RPN queries.
324 Clean-up the CCL API. Moved some internal structures from ccl.h to
325 private header cclp.h. Changed ccl_parser_create so that a Bibset must
326 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
327 This is replaced by ccl_parser_find_str which takes a string instead.
329 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
330 libyaz.la is the core of YAZ except the generic frontend server and
331 does not depend on POSIX threads anymore. libyaz_server.la is the
332 generic frontend server facilities and uses POSIX thread functionality
333 if available. The libyaz.la no longer depends on POSIX threads because
334 the number of global structures is limited. NMEM no longer re-uses blocks
335 between threads ; it simply free's memory immediately but allocates in
336 "large" chunks as usual. We don't expect any performance penalties
337 because of this. The yaz_log system is still using a global log_level so
338 caution must be taken when modifying it with yaz_log_init_.. +
339 yaz_log_mask_str. This, however, should not cause any trouble because
340 these functions are called during initialization of application code
341 anyway. `yaz-config --libs server` returns libs for server applications;
342 `yaz-config --libs` returns libs for non-server applications.
344 New OID database - with public definitions in oid_db.h. Removed old OID
345 database including the head oid.h and definitions such as enum oid_value
346 and struct oident. The new OID database uses the same string names as
347 before but the 'protocol' is gone. There are now only two representations
348 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
349 converts from string to OID; functions with prefix yaz_oid_to_string
350 converts the other way.
352 Change to emit_term() in CQL-to-PQF query translation: when a term has
353 the /regexp relation modifier, do not process it for leading and
354 trailing "^" and "*", which have quite different meanings in regular
357 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
358 write handlers no longer carries a 'last' parameter. This will make
359 yaz_iconv flush "less" characters. A flush is performed by call to
360 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
362 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
363 removed, because function yaz_query_to_wrbuf does the same.
365 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
366 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
368 Deprecated MARC utility functions removed.
370 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
373 Branch split: YAZ_2_1_55_branch
375 --- 2.1.54 2007/03/16
377 Fix to ZOOM-C so that transparent reconnection is properly handled on
378 connections that are in asynchronous mode.
380 Fixed compilation on OpenBSD 4.0.
382 Large strings in GRS-1 records are now properly displayed in yaz-client.
384 Added character conversion support for "advancegreek"; based on patch from
387 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
388 sequence is met. Before the error was not set so it would be unknown.
390 Adjust yaz-marcdump MARC reader so that it skips until record separator
393 --- 2.1.52 2007/03/07
395 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
396 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
397 fd_set structure used as a bitmask for the FDs to be selected on.
399 Using ACX_PTHREAD macro to check for POSIX threads.
401 Fixed have-vsnprintf check.
403 --- 2.1.50 2007/02/23
405 Fixes for configure on BSD. Bug #900.
407 Added snprintf/vsnprintf wrappers for systems that don't have
408 limits (heavens forbid).
410 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
411 created before all previous tasks were completed and removed from the
412 task queue, the new task could be removed by a mistake.
414 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
416 Implemented pass-through CQL-to-PQF conversions. Bug #861.
418 Fixed bug #832: Problem with MARC/charset in yaz-client.
420 Fixed bug #668: save command line history for yaz-client.
422 Fixed bug #830: pkg-config support.
424 --- 2.1.48 2007/01/23
426 Extended ZOOM result set options with two options that may be read by
427 a client: resultSetStatus and presentStatus with values as specified for
429 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
431 Fixed bug #827: Using SSL fails on Debian etch.
433 Fixed bug #826: Weird looking chars for set of MARC records.
435 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
436 that is treated as an ItemOrder with itemRequest being an XML document
437 external. The value of "doc" is the content.
439 Extended the GFS search facility. New member of bend_search_rr
440 'estimated_hit_count' signals that hits is known to be an estmate
441 (higher or lower than real hit count). New member 'partial_resultset'
442 signals that the search was partial (hit count is lower or equal than
443 real hit count). For Z39.50, the information is stored in resultSetStatus
444 member of SearchResponse APDU. For SRU, the information is signalled
445 via SRU diagnostic 59: "Result set created with valid partial results
448 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
450 --- 2.1.46 2007/01/13
452 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
454 Added ZOOM_connection_peek_event.
456 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
457 the following new functions:
458 ZOOM_event_nonblock, ZOOM_connection_process,
459 ZOOM_connection_get_{socket,mask,timeout},
460 ZOOM_connection_fire_event_{timeout,socket}.
461 The existing blocking event handler, ZOOM_event, is a wrapper for the
462 + blocking ZOOM_event_sys_{poll,select}.
464 Implemented function ccl_xml_config which parses XML version of CCL
465 configuration (bug #798).
467 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
469 Added timings utility (yaz/timing.h)
471 --- 2.1.44 2007/01/03
473 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
476 Fixed bug #779: Rotation of apdu.log fails.
478 Fixed for character set conversions:
479 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
480 Honor G1 set in MARC-8 decoding.
482 --- 2.1.42 2006/12/17
484 Fixed bug #775: char conversion does not handle Alternative UTF-8
487 Implemented function yaz_marc_read_line which parses MARC line format
488 records. There is a wealth of formats out there. So far, this function
489 reads line records produced by yaz_marc_write_line.
491 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
492 more generic and easier to remember(!) options: -i format and -o format
493 which specifies input format and output format respectively - where
494 format is one of "marc", "marcxml", "line", "marcxchange".
496 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
497 does not print anything except warnings for records.
499 For yaz-marcdump, added support for MARC split into files (-s) with a given
502 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
503 spec, at http://www.loc.gov/standards/sru/record-update/
504 This has changed the binary layout of the following structs:
505 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
506 bend_update_rr . Patch by Ko van der Sloot.
508 Added GFS utility function bend_assoc_is_alive which returns 1 if
509 association is still alive (client is connected); 0 otherwise (client
510 closed connection). This allows busy servers to stop working for
513 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
514 been a separate piece of software. This version of ziffy has been modified
515 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
517 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
519 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
520 Client code may now interrogate options such as "init_opt_sort" to
521 find out whether the server claims to support various options.
523 --- 2.1.40 2006/11/27
525 Added utilities yaz_{set,get}_esn to set/get element set name from
528 Removed the build of libyazthread.la. The libyaz.so is the threaded version
529 of YAZ and has been so since YAZ 2.1.10.
531 Implemented ZOOM_record_error which returns error information for
532 record (surrogate diagnostic).
534 --- 2.1.38 2006/10/31
536 Updates for SRU Update by Ko van der Sloot:
537 1. Changed name from "operation" to "action"
538 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
539 versions in the code, marked as 'backward compatible'.
540 3. Added diagnostics for SRU Update.
542 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
544 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
546 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
548 For GFS, fixed problem with SRU diagnostic 'First record position out of
549 range' being issued for 0 hits.
551 zoomtst10 part of Windows Build.
553 --- 2.1.36 2006/10/13
555 Implemented yaz_filepath_comp which splits a path into file path
556 components (required by Zebra 2.0.3+).
558 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
559 BSD inspired license until now so this should not have any real impact on
560 anybody. See http://www.opensource.org/licenses/bsd-license.php
562 Fixed bug #687: Missing log lines.
564 Fixed bug #678: CQL to PQF translation does not preserve double-quote
567 Fixed bug #689: SRU diagnostics to be added.
569 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
570 whether a connection is idle (no more work do do).
572 --- 2.1.34 2006/10/04
574 Change type of optval from long to int for invocation of setsockopt with
575 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
577 Added support for specifying the max log file size for the Generic
578 Frontend Server. The size is given with option -r.
580 --- 2.1.32 2006/09/21
582 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
584 --- 2.1.30 2006/09/17
586 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
589 Fixed bug in Generic Frontend Server that could cause a server to stop
590 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
592 For the generic frontend server, the maximum record size is used as maximum
593 size of incoming packages (SRU + Z39.50). The value until was previously
594 only used in Z39.50 Init negotiation and, later, in a session controlled
595 sizes of records returned. This is controlled using -k option. It can be
596 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
598 --- 2.1.28 2006/09/04
600 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
603 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
605 New option for yaz-marcdump -lpos=value which allows setting a portion
606 of MARC header to a certain value.
608 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
610 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
611 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
613 --- 2.1.26 2006/08/15
615 Fixed problem with SRU mode type (soap, get, post) for yaz-client
618 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
620 --- 2.1.24 2006/08/08
622 Fixed MARC ISO2709 encoding routines to deal with character set
625 Minor changes to GFS logging. Database included in search request log
628 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
629 cached/multiple records.
631 Shared libraries are built by default on Unix+configure.
633 Changed cql2pqf transformation to use a different evaluation order. The
634 new order is: always, relation, structure, position, truncation, index
635 and relationModifier. Old order was: always, relation, relationModifier,
636 structure, index, position, truncation. Note that the the latter ones
637 override former ones for identical attributes.. The new scheme means that
638 it is possible to override any existing attribute with a relationModifier.
639 And also that it is possible to override everything for the index rule
640 (except the ones listed in relationModifier). No order is perfect but this
641 one, we believe, covers more real cases.. The "always" should have been
642 called "default", since the attributes there can be overridden with all
645 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
646 compilation phase, but also for yaz-config --cflags output. This allows
647 us to have public headers with Libxml2 stuff in them . It should also,
648 eventually, make Libxml2 checks redundant in packages using YAZ, such
651 --- 2.1.22 2006/06/15
653 Changed SRU update structure bend_update_rr so that SRU diagnostics are
654 stored in uri, message and details.. Previously diagnostics were stored
655 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
656 compatibility.. but he's probably the only one affected, so.
658 Added support for CCL, compiled on the client side, in ZOOM-C. This
659 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
660 input; the resulting query objects can be used for for searching with
661 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
663 YAZ' configure searches for OpenSSL by default.
665 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
666 SL_CTX_use_certificate_file. See
667 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
668 for more info. Thanks to Ko van der Sloot.
670 --- 2.1.20 2006/06/02
672 Bug #600: SRU GET, POST support for yaz-client. Introduced
673 command 'sru' which selects method SOAP/GET/POST.
675 Allow missingValueAction to be specified for the sortspec string -
676 function yaz_sort_spec. By default, the missing value action is null.
677 Use ! to specify "abort". Use = followed by stringvalue to specify default
680 Ensured that Present-handler (if defined) is called in GFS before any call to
681 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
682 searchRetrieve requests.
684 Documentation for YAZ is now based on the Docbook XML/XSLT using
685 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
686 is no longer depending on jade/openjade or docbook-to-man scripts.
687 PDF is no longer part of the distribution - but can optionally be
688 made using DSSSL/jadetex or FOP.
690 Added retrieval handling support in Generic Frontend Server to support
691 conversion between MARC/XML as well as XSLTtransforms. See
692 etc/yazgfs.xml for an example.
694 Added Authentication support to Generic Frontend Server in SRU
695 mode. Authentication using HTTP Basic is supported, as is the use
696 of 'x-username' and 'x-password' parameters in the request itself.
698 Added support for a new character set MARC8s identical to MARC8 except
699 that it converts combined characters to single Unicode characters in the
700 Latin-1 range (when possible).
702 --- 2.1.18 2006/04/24
704 ASN.1 compiler 0.4: generates brief Doxygen file header for
705 generated .h/.c files.
707 Utility yaz_iconv now supports conversion to MARC-8.
709 New facilities for the MARC module. The reading - and writing of
710 content are separate methods for the yaz_marc_t handle. The following
711 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
712 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
713 format). Write functions have prefix yaz_marc_write_.. The existing
714 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
715 available. Removed support for OAI-MARC and simplexml (not the
716 simplexml from PHP5).
718 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
719 to be returned for this connection.
721 --- 2.1.16 2006/03/31
723 Allow multiple languages and charsets to be specified with
724 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
725 negcharset iso-8859-1,utf-8
727 Translation of proximity nodes from CQL into PQF now works.
729 Moved to automake 1.8, 1.9.
731 Added function yaz_log_set_handler which allows a log handler to be
732 installed. This handler will be called for all log messages. Output
733 to file is also produced; but that can be disabled by passing NULL
734 fname to yaz_log_init_file.
736 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
738 For SRW (including GFS), accept application/soap+xml as content-type
741 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
742 produces NO stylesheet reference even if a default stylesheet is specified
745 --- 2.1.14 2006/03/14
747 Updated Windows package to include yazd.dll + yazd.lib for the
748 Development component.
750 If the environment variable YAZ_LOG is set, then it is used as a
751 string indicating the default level of logging to use if not
752 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
753 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
754 used as before. So, for example, to omit warnings from YAZ logging,
757 cql_transform() now map structure and other attributes before indexes,
758 so that index-specific structures and other attributes can override
759 defaults. So now a combination of mapping specifications such as:
761 index.dc.date = 1=date-modified 4=5
762 does the right thing.
764 cql_transform() now also respects the "always" mapping specification,
765 which establishes an initial set of attributes to be used for all
766 terms except where overridden by more specific attributes associated
767 with the index, relation or modifier.
769 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
770 which mode to use; one of "post", "get" or "soap" (SRW, default).
772 Fixes for yaz_iconv routines: changed trie-based character set conversions
773 to use only non-negative values for bit fields due to Sun's C compiler not
774 supporting negative values.
776 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
777 sequences where not read correctly. Fix by Rustam Usmanov.
779 Updated win/makefile to use options, settings which makes things
780 compile with VS C 2005.
782 --- 2.1.12 2006/02/01
784 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
786 In ZOOM socket code, use select instead of poll on MacOSX.
788 ZOOM-C now support client-side compilation of CQL into RPN that is
789 sent to the server, enabling CQL to be used against all Z39.50
790 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
791 ZOOM_query object, and submit it using ZOOM_connection_search().
792 The CQL-to-RPN translation uses a configuration file, the name of
793 which must be specified in the Connection's "cqlfile" option.
795 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
796 function, which takes as its start-term parameter a ZOOM_query object
797 (which may have had either CQL or RPN set into it).
800 --- 2.1.10 2005/11/29
802 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
803 GFS to support this as well. Backend handler, bend_srw_update, does the
804 update work. Code contributed by Ko van der Sloot.
806 Allow retrieval of Search Result-1 information in ZOOM by the use of
807 options that are attached to a result set. ZOOM documentation updated
810 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
811 UTF-8 conversion. Patch by Raj Patel.
813 Added option -m to GFS to control formatting of timestamps in log file.
815 Added 'exit' as synonym for 'quit' in yaz-client
817 Added support for specifying SRW resultSetId + resultSetIdleTime in a
818 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
819 for the new members. Patch by Ko van der Sloot.
821 Added support for SRU POST. It is supported for content-type
822 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
824 Do not build the separate Multi-threaded (MT) library libyazthread.la.
825 Instead make the library libyaz.la multi-threaded. Threading as a whole
826 can still be disabled by configure option --disable-threads. Previosly,
827 with older GLIBCs there were problems with MT libs under Apache. This
828 has now been fixed a long time ago.
830 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
833 CQL module modified to be case insensitive for relations/indexes/operations.
835 Fixed bug in CQL transform code: incorrect value relationModifieder
838 Added 'show all' command for yaz-client which retrieves all results
841 Added new yaz-client, xmles, which takes a (private) OID and
842 a document to be sent as an extended service request.
844 Describe new yaz-client commands wait_response and set_auto_wait.
846 Increase TCP/IP listener backlog from 3 (which I am guessing was
847 copied from the SunOS manual entry way back when) so SOMAXCONN, so
848 that the socket will queue as many incoming connections as it's able
849 to handle ongoing connections. In other words, it will never now
850 refuse a connection that it would be able to handle merely because
851 it's not got around to accepting() enough of the pending connections
852 yet. This is the behaviour anyway under Linux, where the listen()
853 argument is ignored; but not under BSD and on systems such as
854 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
855 YAZ-based servers should now be uniform across operating systems in
858 yaz-marcdump uses 64-bit file access on some systems. This is enabled
859 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
860 This allows yaz-marcdump to read large MARC batches (>2 GB).
862 Modified all YAZ source files - except the source which is auto-generated
863 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
866 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
867 corresponding to the existing *_setl() function. These allow option
868 values containing arbitrary valuues.
870 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
871 ZOOM_resultset_sort() in new applications. Its behaviour is identical
872 except that it returns an indicator of whether or not the sort
873 criterion was accepted (0 for OK, -1 for invalid).
877 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
878 MARC output rather than returning "new" buffer.
880 yaz-client warns about unknown init options.
882 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
886 Added support for SRW sort in Generic Frontend Server. Patch
887 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
888 sortKeys - or NULL if none is provided.
890 Fixed bug #307: It was impossible to specify indefinite/no timeout
891 for ZOOM_event. Special timeout value -1 now means indefinite timeout
894 Added support for multiple languages and charsets to be specified in
895 ZOOM. Each charset/language is separated by a blank. If negotiation is
896 in effect in init-response, Option
897 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
898 Code based on patch by Vasiliy Osadchuk.
900 Fixed bug #306: infinite recursion that occurred when calling
901 yaz_log_level_init as the first call (before other log level or
904 Fixed bug in scan handling in front end server: if preferred-Position-In-
905 Response was non-present, a NULL pointer referece was performed.
909 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
910 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
911 now defined for all those error codes. So instead of putting 109 in
912 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
913 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
915 Modified the yaz-marcdump utility to skip garbage bytes between MARC
918 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
920 Program yaz-client now exits and produces an error message if multiple
921 Z39.50 servers are specified on the command line (none or one allowed
924 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
929 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
931 Fixed bug #272: Preserve spacing for CCL terms.
935 Added support for virtual hosts and multiple backend servers for
936 the YAZ frontend server. The configution is XML based and
937 support specificition of CQL to RPN mappings and explain information.
938 See section "Virtual Hosts" in the YAZ manual.
940 Extended OPAC display utility. OPAC display utility renders
941 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
942 to supplement yaz_marc_decode_wrbuf.
944 Fixed a bug in MARC decoder that could caused it to crash for some
945 invalid MARC records. More diagnostics and warnings where added in
946 XML output (warnings, etc are stored in comments).
948 --- 2.0.34 2005/02/08
950 Fixes for UNIX domain sockets. Bug #261.
952 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
954 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
955 Added yaz_marc_subfield_str which defines subfield lead string which is
956 used in YAZ_MARC_LINE format. Default string is blank+$. Added
957 yaz_marc_endline_str which defines end of fields string used in
958 YAZ_MARC_LINE format. Default string is newline.
960 Experimental support for MarcXChange. This format can be produced
961 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
962 http://www.bs.dk/standards/MarcXchange.xsd
964 Added yaz-client commands scansize that sets maximum number of
965 entries to be returned by scan.
967 --- 2.0.32 2005/01/11
969 Added support for SRW scan in yaz-client and Generic Frontend Server.
971 * Added whereInList member to SRW Scan Term.
973 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
975 Fixed NMEM system to return aligned blocks on the smallest boundaries
976 that are suitably aligned for all possible types on the particular
977 architecture YAZ is being built for.
979 --- 2.0.30 2005/01/04
981 Fixed numerious warnings that was issued with newer versions of GCC.
983 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
984 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
987 Make YAZ Generic Frontend Server slightly faster.
989 Enhance (and reduce) logging for Generic Frontend Server.
991 Revert YAZ log system so that it flushes every write operation
992 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
994 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
995 instead of LOG_, due to name clash with syslog(3). LOG_ are still
996 present. New applications should define YAZ_USE_NEW_LOG=1 - this
997 will effectively disable old definitions.
999 --- 2.0.28 2004/11/09
1001 Added yaz_log_time_format which specifies log format using
1004 Added yaz_log_module_level which returns mask for a module. Value
1005 is non-zero mask a if module is enabled; zero if disabled.
1007 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1008 in include/yaz/cql.h.
1010 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1012 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1014 Fixed bug #172: RPM builds does not enable SSL.
1016 Doxyfile.in part of dist. Doxyfile generated by configure.
1018 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1019 are given and the corresponding component does not exist.
1021 Extend CCL documentation in YAZ reference. Describe r=r.
1023 --- 2.0.26 2004/10/01
1025 Fixed MARC->MARCXML conversion to properly deal with
1026 fields, subfields, indicators having non-ASCII characters.
1028 Fixed MARC->MARCXML conversion so that ASCII control characters
1029 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1032 Added YAZ GFS support for conversion from Z39.50 surrogate
1033 diagnostics to SRW surrogate diagnostics.
1035 Bug fix: YAZ GFS did not return schema in explainResponse.
1037 --- 2.0.25 2004/09/30
1039 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1040 now converts recordSchema to elementSetName as well as schema URI.
1042 Fixed bug in COMSTACK that prevented HTTP request packages from being
1045 --- 2.0.24 2004/09/29
1047 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1048 does not require white-space before and after the dash in a range, e.g.
1049 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1052 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1053 due to new GCC removing "redundant" code.
1055 Added yaz-client commands scanpos and scanstep that sets preferred
1056 position and step-size for scan.
1058 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1060 Added CCL utility ccl_qual_buf which parses one or more CCL
1061 spec lines in a buffer.
1063 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1064 of name and value - ignoring empty lines and comments.
1066 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1068 Added odr_get_element_path which returns current element path for an
1069 ODR handle. This utility is useful in error handling or user-defined
1072 Added ODR_PRINT utility odr_set_stream which is is a more generic
1073 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1074 to a write function and pointer to close function. The close function - if
1075 non-NULL - will be called during odr_destroy.
1077 Fixed bug in CCL parser where truncation char was not removed from
1078 right side when truncation=both was in effect.
1080 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1083 --- 2.0.23 2004/08/11
1085 Fix buffer overrun in CQL parser when dealing with proximity (%).
1087 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1088 to UTF-8/UCS conversion is now only based on codetables.xml.
1090 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1092 --- 2.0.22 2004/08/06
1094 Add support for more "commit changes" in ZOOM (uses Extended Services).
1096 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1099 Yet another small fix for configure of SSL.
1101 --- 2.0.21 2004/05/14
1103 Fix SSL libs for configure when --with-openssl=DIR is given.
1105 --- 2.0.20 2004/05/10
1107 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1109 SSL comstack now uses yaz.pem certificate file on server side
1110 by default. Certificate filename can be configured by calling
1111 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1113 Fix bug regarding multiple calls to ZOOM_connection_connect.
1115 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1117 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1118 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1120 ZOOM now allows inspection of X509 peer certificate for verification.
1121 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1123 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1124 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1125 as "modular" but it simplifies things.
1127 Added cs_get_peer_certificate to that returns peer X509 PEM.
1129 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1130 NULL if SSL is unavailable.
1132 Documentation about MARC decoding tools.
1134 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1136 --- 2.0.19 2004/03/30
1138 Rename CHANGELOG to NEWS to follow GNU style packing.
1140 Fix bug with missing initialization of member in init_diagnostics.
1141 This bug affects threaded version of GFS server.
1143 --- 2.0.18 2004/03/20
1145 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1148 Ensure zlib.dll is packed with Windows install.
1150 --- 2.0.17 2004/03/17
1152 Fix encoding of xsd:string to use text instead of CDATA.
1154 Fix endless loop in CQL parser with unbalanced ".
1156 Use a more compact way to store MARC-8 conversion tables.
1158 --- 2.0.16 2004/03/16 Debian only
1160 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1163 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1168 --- 2.0.15 2004/03/01
1170 Another fix for decoding of XML packed records.
1172 --- 2.0.14 2004/02/25
1174 Fixes for Chunked encoding. White space not ignored after length spec.
1176 Update NS and use default NS for SRW diagnostic elements.
1178 --- 2.0.13 2004/02/23
1180 Implement ZOOM_resultset_cache_reset which resets record cache.
1182 Implement ZOOM_resultset_sort which sorts a result set.
1184 Implement chunked HTTP transfer.
1186 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1188 --- 2.0.12 2004/02/16
1190 Added member 'schema' to bend_explain_rr structure so that backend
1191 can specify explain record identifier. Defaults to Zeerex 2.0.
1193 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1195 --- 2.0.11 2004/02/16
1197 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1200 Added init command for yaz-client which sends "extra" init request.
1202 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1203 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1205 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1207 Make ZOOM error code for "invalid query".
1209 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1211 --- 2.0.10 2004/02/05
1213 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1216 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1218 Added option -p <file> to make Generic Frontend Server to write PID file.
1220 Added option -D to put Generic Frontend Server in background on its own.
1222 Make ZOOM C recognize option "password". If unset, "pass" is used
1223 (for backwards compatibility).
1225 Fixed a bug in Generic Frontend Server that could make it crash if a
1226 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1229 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1230 Must be issued before open, in order to be in effect.
1232 --- 2.0.9-6 2004/01/12 Debian/Windows
1234 Make the SRU server more picky WRT unknown params, etc.
1236 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1238 New YAZ client command, options, that sets Z39.50 options.
1240 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1241 options from a string of tokens (one token for each option bit).
1243 Update SRW diagnostic code messages.
1245 --- 2.0.9-5 2004/01/07 Debian/Windows
1247 Handle user defined stylesheet for SRW/SRU.
1249 --- 2.0.9-4 2004/01/06 Debian/Windows
1251 Fix bug in decoding of Content-Length.
1253 --- 2.0.9-3 2004/01/06 Debian/Windows
1255 Fix a bug with decoding of XML packed records.
1257 --- 2.0.9-2 2004/01/05 Debian only
1259 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1261 Fix bug in SRW/SRU diagnostics decoding.
1263 --- 2.0.9 2004/01/05
1265 Fixed bug in Generic Frontend Server which could drop records exceeding
1266 preferred message size. Reported and fixed by Irina Dijour.
1268 Fixed calculation of package size for structured records in Generic
1269 Frontend Server. Reported and fixed by Irina Dijour.
1271 Fixed namespace for SRW/SRU diagnostics.
1273 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1275 --- 2.0.8 2003/12/22
1277 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1278 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1281 CQL changes to reflect recent changes to the specification:
1282 * Documentation talks about context sets instead of index sets.
1283 * Documentation talks about indexes instead of qualifiers.
1284 * The CQL-to-PQF transformer's configuration file now uses
1285 "index.set.name = <attributes>" instead of the old form
1286 "qualifier.set.name = <attributes>". (Both forms are still
1287 understood but the latter is deprecated.)
1288 * CQL terms with no explicit index specified are now interpreted as
1289 cql.serverChoice instead of srw.serverChoice (which of course
1290 behaves exactly the same.)
1292 --- 2.0.7 2003/12/16
1294 MARC conversion can now generate ISO2709 output in another
1295 character set. yaz-marcdump uses this facility if you invoke it
1298 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1299 functions from there can be used from C++.
1301 --- 2.0.6 2003/12/04
1303 Frontend server now transfers memory from decoded packages to stream
1306 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1307 references to show up.
1309 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1310 the ZOOM Abstract API. The older names for the same options are still
1311 also supported for the benefit of old applications.
1313 ZOOM-C supports "implementationId" and "implementationVersion" options
1314 to go along with "implementationName". These allow the user code to
1315 specify identification strings to be sent to servers.
1316 Add OID for the new ExtLite attribute set.
1318 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1319 as requested/supplid by Ere Maijala <ere@atp.fi>
1321 For generic frontend server, reverse the order of
1322 "toolkit-supplied / application-supplied" strings sent as implementationId,
1323 Name and Version. Also, remove the spaces around the slash. This brings
1324 the GFS in line with the behaviour of ZOOM-C on the client side.
1326 Add function ZOOM_scanset_display_term.
1328 yaz-client shows scan displayTerm if present.
1330 Utility yaz-iconv is now installed by default along with the man page
1333 Extend configure check for OpenSSL to use pkg-config where available (such
1336 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1337 server to specify uid/gid/mask for socket using the format
1338 unix:[user=uid,][group=gid,][umask=mask,]file=path
1339 If file= is omitted the existing format is assumed, e.g.
1341 in which case the mask is 0666 (rw for everybody).
1343 Major restructure of YAZ source. All source in libyaz is in src directory.
1344 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1345 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1347 Added man page for utility yaz-marcdump (used to be called marcdump).
1348 yaz-marcdump is installed by 'make install'.
1350 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1351 of incoming package failed.
1353 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1355 Change prototype of odr_perror: add const to message string.
1357 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1359 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1360 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1361 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1362 DNS lookup. There should not be any compatibility problems with this
1363 assuming that blocking=1 or 0 is used.
1365 Fix bad reference in UNIX comstack in function cs_addrstr.
1367 Fix for compilation on AIX.
1369 The generic front-end server (server/seshigh.c) now supports returning
1370 Init diagnostics to the client in User-information-field, in
1371 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1374 --- 2.0.4 2003/09/04
1376 Allow any CQL relation (not just all,any,exact,scr).
1378 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1379 that features the same UI.
1381 Implemented command update0 in YAZ client which is equivalent to
1382 update but uses old of Ext Update ASN.1.
1384 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1385 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1386 Previously no OID was used for this info.
1388 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1389 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1390 returns 'malformed search term' otherwise.
1392 SortResponse member resultCount now set to NULL in sort handler of
1395 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1398 Add three new utility functions for translating OIDs between various
1399 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1400 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1401 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1402 char *oid_to_dotstring(const int *oid, char *oidbuf);
1403 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1405 Reverted modifications for ES Update definition for z_IU0Update
1406 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1407 is back to YAZ 2.0.2.
1409 String value attributes for CCL parser.
1411 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1412 which their FirstSearch server returns in Init responses, sometimes
1413 carrying useful diagnostic information when Init fails. This has the
1414 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1415 "z39.50/oclcui.asn", where its definition is somewhat different from
1416 what OCLC document on their web-site, as required to interoperate with
1419 Support for anonymous authentication in yaz-client. Use the command
1422 * Fix the OID of the Index Data-local "admin" Extended Service from
1423 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1424 the 1000, which indicates a locally-defined OID, was a mistake.
1426 --- 2.0.3 2003/06/20
1428 Fix CCL directive @case handling so that it affects string match for
1429 both CCL keywords and qualifiers.
1431 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1432 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1433 Decoder has been updated with ASN.1 changes as listed in
1434 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1435 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1436 z_IUUpdate, remains unchanged.
1438 ZOOM_record_get may now return a record in a specific character set.
1439 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1440 "from" is the character set of record as returned by target. "to" is
1441 the character set to be returned. If omitted, "to" is UTF-8.
1443 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1445 New ODR utility, odr_getelement, which returns name of element for
1446 which encoding/decoding failed.
1448 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1449 in cases where a required element was omitted.
1451 Bug fix: some MARC8 sequences were not converted.
1453 New ZOOM option "step" which specifies number of records to be
1454 retrieved in one chunk. Used in conjunction with "start" and "count".
1456 SRW support for yaz-client. Use scheme http: to use it, e.g.
1459 yaz-client no longer does (un)intelligent character set conversions
1460 by default. Can be enabled with charset and marc_charset commands.
1462 xmalloc trace fix for 64-bit systems such as DEC alpha.
1464 Solaris 2.6 compile fix.
1466 New function, cql_strerror() translates SRW error codes, as returned
1467 by cql_transform_error(), into human-readable English strings. Used
1468 in yaz-client diagnostics when appropriate.
1470 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1471 converts it into a type-1 query which is sent to the server. This
1472 makes CQL available for use with all Z-servers, as opposed to the tiny
1473 minority that can handle CQL queries themselves.
1475 --- 2.0.2 2003/04/28
1477 New Debian package layout similar to the Redhat Package layout.
1479 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1480 and search result respectively.
1482 --- 2.0.1 2003/04/25
1484 Redhat package is now several packages: libyaz (runtime libraries),
1485 libyaz-devel (development and documentation, and yaz (utility programs).
1486 Package spec file by Morten Bogeskov.
1488 New member 'schema' in struct bend_fetch_rr which the name of requested
1489 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1490 handler MAY set this to reflect the schema of the returned record.
1492 New member 'display_term' in struct scan_entry. GFS now sets member entries
1493 and allocates scan entries to be filled by user scan handler. In previous
1494 version, entries member was allocated by the scan handler. That still works,
1495 but the GFS will ignore member display_term - assuming it was NOT set by
1496 the handler. The fact that the GFS now allocates the entries both allows
1497 for new members and makes a scan handler easier to write.
1499 Fix CQL lex buffer overflow.
1501 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1502 SRU default recordPacking is string.
1504 SRU protocol support for frontend server.
1506 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1508 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1510 Added scan for the ZOOM shell (zoomsh).
1514 * String Identifers for Schemas (Amendment 5).
1515 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1516 Old definition for schema
1517 Odr_oid *schema; /* OPT */
1522 Z_InternationalString *uri;
1523 #define Z_Schema_oid 1
1524 #define Z_Schema_uri 2
1527 * resultCount parameter to Sort Response (Amendment 1).
1528 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1530 Support for SRW 1.0 over HTTP. This is an optional feature and
1531 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1534 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1535 on the same port. SRW SearchRetrieveRequests are mapped
1536 to bend_init,bend_search,bend_fetch,bend_close.
1538 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1540 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1541 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1543 ZOOM connections are SRW based if schem http is used for hostname
1544 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1545 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1547 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1548 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1549 distance=n, order=true/false, relation=le, prox unit=word. If
1550 n is omitted, distance 1 is used.
1552 Fixed problem with C compiler include path in wrong order.
1554 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1555 on Solaris. Patch from Ko van der Sloot.
1557 New MARC decode API. All new functions operate on a yaz_marc_t
1558 handle. The most important new functions are: yaz_marc_create,
1559 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1560 decode and destroy respectively. Decoder can produce formats
1561 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1562 include/yaz/marcdisp.h.
1564 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1565 to UTF-8, UCS-32, wchar_t or Latin-1.
1567 * Prototypes for yaz_iconv_-functions moved to separate header
1568 include/yaz/yaz-iconv.h.
1570 Make a few private functions 'static' in unix.c. This prevents
1571 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1573 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1574 are set when Init Response is received.
1576 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1577 but returns diagnostic set as well.
1579 New function yaz_strerror which is a portable wrapper for
1580 strerror/strerror_r/GetLastMessage.
1582 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1583 is returned for MARC. If type is "oai", then OAI MARC is returned.
1585 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1588 --- 1.9.2 2002/11/26
1590 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1592 Fix bad race conditions on SIGTERM and terminate gracefully in
1595 Move retrieval (data1) module to Zebra since nobody seems to be
1598 Add GRS-1 render for ZOOM using same format as yaz-client.
1600 --- 1.9.1 2002/10/05
1602 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1604 Fix broken ESpec handling in data1 module.
1606 SGML reader parses comments and makes them part of the data1 tree.
1608 Added several type casts so that YAZ compiles as C++ code.
1610 ZOOM didn't handle PDU encoding failures properly.
1612 Added more Bib-1 diagnostics (approved extensions).
1614 GNU configure: better check for iconv.
1616 More portable use of accept, getpeername. Check for socklen_t. Use
1617 int/size_t if socklen_t is not defined.
1621 PQF parser rejects bad queries - including those with extra
1622 characters in them. PQF parser used to silently ignore that.
1623 Cleaner API for PQF added, which allows you to get detailed
1624 error information for bad queries (see yaz/pquery.h).
1626 Fixed bug in ZOOM_record_get for type "database".
1628 Implemented mini iconv library supporting conversions between
1629 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1631 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1633 --- 1.8.9 2002/08/20
1635 Fixed ZOOM C record cache so that preferredRecordSyntax and
1636 elementSetName is used to check for already fetched records.
1638 --- 1.8.8 2002/08/02
1640 Added three members in bend_initrequest structure to facilitate
1641 character set negotiation.
1643 Fixed a bug in frontend server that could cause indefinite
1644 loops under rare conditions.
1646 Revised character set utilities (charneg.h) so that encoding
1647 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1649 For PQF, directive @term <type> sets term type for Scan/Search.
1650 Here <type> is general, string, numeric, null. The term type
1651 is inherited - just like @attr.
1653 New call odr_set_charset that sets character set conversion for
1654 international-strings on a ODR stream. Prototype is:
1655 int odr_set_charset(ODR o, const char *to, const char *from);
1656 The InternationalString is still represented as C string in YAZ
1657 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1658 won't). On the protocol level, you can use any encoding.
1660 Support for UNIX sockets in ZOOM.
1662 Solaris recv sometimes returns errno == ENOENT. It is treated as
1663 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1665 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1666 both client and server. Code by Morten Bogeskov.
1668 --- 1.8.7 2002/05/22
1670 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1671 that they can be used directly from Visual Basic. You must recompile
1672 your windows APP if you're using ZOOM.
1674 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1675 Commands "lang" and "charset" sets language and character set respectively.
1676 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1677 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1679 Attributes from multiple CCL fields may be OR'ed rather than merged
1680 using directive "@field or". Fields are still merged by default -
1681 equivalent to "@field merge".
1683 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1686 Fixed bug in zget for parameter ExtendedServicesResponse.
1690 --- 1.8.6 2002/03/25
1692 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1694 Client displays USR.1:SearchResult-1 (hits per term).
1696 Additional Search Info for search in Generic Frontend Server.
1698 Fixed CCL parsing of "field=s".
1700 WIN32 installer - using the excellent NSIS software from nullsoft.
1702 Fixed CCL parsing of "field = - <number>".
1704 Added function yaz_marc_decode that decodes MARC for line mode
1705 display or XML (similar to that used by JZKit).
1707 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1708 Z39.50. But ISO/ILL was, however.
1710 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1711 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1713 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1714 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1716 --- 1.8.5 2002/02/03
1718 New YAZ client features: Command completion and new commands:
1719 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1720 Code provided by Jacob Poulsen.
1722 New call oid_trav, that visits all registered OIDs via callback.
1724 Function ZOOM_record_get now returns const char pointer rather than
1725 void pointer. It saves a lot of type casts.
1727 For YAZ client, command "auth" now allows you to set authentication
1728 in IdPass style. It is enabled when three tokens are given - order
1729 is user, group and password.
1731 Fix memory leaks in MARC record handling for ZOOM.
1733 New option for YAZ client, -k <kilobytes> that sets
1734 maximum record size. Similar to -k option for generic frontend
1735 server and yaz-ztest.
1737 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1739 Prefix query parser reports "fail" when bad attribute set is given.
1741 Fix in MARC decoder. Proximity logging. Fix for attribute set
1742 in scan handler for server. Patches by Shigeru Ishida.
1744 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1747 Configure option --with-openssl=<dir> now works when a directory is
1748 specified. Patch provided by Morten Bogeskov.
1750 New option for YAZ client, -u <auth>, that sets authentication.
1752 ZOOM fix: error information was sometimes "missing", since error
1753 was cleared/reset too when it shouldn't.
1755 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1757 --- 1.8.4 2002/01/04
1759 Scan for ZOOM API. New object ZOOM_scanset. New functions
1760 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1761 ZOOM_scanset_destroy.
1763 New ZOOM function, ZOOM_connection_last_event, that returns type
1764 of last event (such as "receive data", "send data", "apdu received",
1767 New ZOOM option, schema, that specifies schema for retrieval.
1769 New CCL feature. Qualifiers can be aliases for one or more
1770 other qualifiers (if more than one is given, OR is used).
1772 ZOOM uses named result sets if target supports it.
1774 Two new YAZ client commands: . (dot, which sources a script of YAZ
1775 client commands), and ! (to execute shell command.). Implemented
1778 Working on Debian packages.
1780 --- 1.8.3 2001/11/19
1782 YAZ client enables named result sets only if target supports it.
1784 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1786 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1787 with key="host" to get same result.
1789 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1790 Function Z3950_resultset_record(s) returns references to records
1791 "owned" by resultset. To become owner use Z3950_record_clone.
1793 Function z_ext_record handles Extended Services. Thanks to
1796 --- 1.8.2 2001/11/12
1798 CCL Parser fix: ignore token comma when dealing with and-lists.
1800 Documentation updates for COMSTACK.
1802 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1803 Changed prototype Z3950_records. For some functions, int parameters
1804 were changed to size_t.
1806 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1809 New MARC decode/display function, marc_display_exl, which properly rejects
1810 non-ISO2709 records. YAZ client uses it.
1812 --- 1.8.1 2001/10/29
1814 Fix bug: local attribute set wasn't set correctly in PQF strings.
1818 * Old Z39.50 codecs no longer supported.
1820 Added ZOOM C binding. See http://zoom.z3950.org/
1822 Renamed states for COMSTACKs to avoid confusion with events.
1824 Implemented cs_look and proper cs_rcvconnect.
1826 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1828 Configure detects POSIX threads on OpenBSD.
1830 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1831 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1833 When error is returned from present handler, non-surrogate diagnostic
1834 is returned in present response (and fetch handler is no longer called).
1836 * Minor adjustments to pquery parser (PQF). Token characters may be
1837 escaped by using backslash (C-style).
1839 PQF parser allows string attribute values to be specified. For @attr,
1840 non-numeric characters after the equal-sign are treated as strings
1841 (e.g. @attr 9=title).
1843 CCL trunction character may be defined (@truncation in file)
1845 * function zget_ExtendedServicesRequest sets waitAction to
1846 waitIfPossible (was wait).
1848 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1851 CCL operator names may be set in field definition files (CCL_bibset).
1852 See ccl/bib1 for an example.
1854 Fixes in ASN.1 compiler for C++ compatibility.
1856 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1857 and "op_or" to avoid conflict with C++.
1859 Fixed problem with GNU readline detection on Redhat 7.0.
1861 Added step-size for Scan backend handler.
1863 Fixed bug that made the frontend server crash when no attribute
1864 set was specified for scan.
1866 Front-end server automatically switches to original working directory
1867 when installed as an NT service. Previously -w had to be specified to
1870 Added extended attributes for retrieval module (data1), so that data1
1871 records carry d1_readXML/SGML attributes. d1_read also supports
1872 null-data rules ( <tag/>)
1874 On UNIX when POSIX threads are available, a separate library libyazthread
1875 is created. Programmers should link with that library and the yaz library
1876 when using threads. The reason for the split was that some applications
1877 on Linux, such as Apache, doesn't work well when using shared objects that
1880 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1881 (or any frontend server) in SSL mode by specifying ssl: followed by
1882 address. Only tested on UNIX.
1884 Added feature for CCL module. Virtual structure s=al or s=ol generates
1885 and-list and or-list respectively instead of phrase search.
1889 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1890 log_mask_str. This was done to avoid name conflicts with other libraries
1891 (such as other PHP extensions).
1893 Added raw OID member for preferred record syntax (request_format_raw)
1894 and returned record syntax (output_format_raw) for backend fetch method.
1896 Config file yaz-config now accepts options so that it returns specific
1897 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1899 Shared library support for UNIX using GNU libtool.
1901 * Modified backend interface. Request/Response struct's replaced by
1902 one read/write C struct. For example bend_fetchrequest and
1903 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1904 Every handler - even search has to be registered in bend_init
1905 handler. This means that the YAZ library no longer refers to
1906 external functions and it makes it possible to make the whole
1907 thing a single DLL/SO.
1909 Added Segment handler for backend server.
1911 Added Zmbol/Zebra administrative functions to YAZ client.
1913 Threaded frontend server on UNIX (when POSIX Threads are available).
1914 Starting the server with option -T enables multi-threading.
1918 Added configure option --enable-comp/disable-comp to control use
1919 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1920 located in sub directory asn.
1922 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1923 in ${exec_prefix}/bin along with the other programs yaz-client and
1926 GNU automake used to maintain makefiles.
1928 Added several OID's.
1930 Changed retrieval module so that we can load records with no abstract
1931 syntax defined. Tagpaths in these records are fully composed of string
1934 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1938 On UNIX, the generated makefile now supports a proper 'make install'.
1939 The prefix can be set via GNU configure to set the install location
1940 (default is /usr/local).
1942 * YAZ programs client and ztest were renamed to yaz-client and
1943 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1944 locations, such as /usr/bin,/usr/local/bin,etc.
1946 * YAZ Header files were moved from include to include/yaz. YAZ Header
1947 files are referred to as include <yaz/log.h> rather than <log.h>.
1948 The YAZ include path (-I ..) is therefore the same as before. Programmers
1949 should update their #include statements or use -Ipath/include/yaz
1950 instead. The main motivation for doing this change is that YAZ header files
1951 can be installed in "standard" locations /usr/include,/usr/local/include
1952 without introducing conflicts, since ALL YAZ header files are stored
1953 in subdirectory yaz (under /usr/include for example).
1955 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1956 rather than project/workspace files. We switched because project files
1957 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1960 Changed name of logging function, logf, to yaz_log, to prevent name
1961 clash with some math-log functions. The YAZ header log.h defines logf
1962 to yaz_log (#define) so there should be no incompatibilities by this
1965 Added bend_start/bend_stop handlers for server. These handler are
1966 called on start/stop of server. For windows they are called whenever
1967 a service is started/stopped.
1969 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1970 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1971 in util/yc.tcl. The auto-generated C code structures are, in a few
1972 cases, incompatible with the old decoders. There are differences in the
1973 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1974 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1975 The preprocessor variable ASN_COMPILED is defined when the compiled
1976 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1977 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1978 wish to use the old encoders/decoders you can specify --disable-yc
1981 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1982 version so that it supports both new - and old version of DB Update
1984 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1985 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1986 change. The name parameter can be set to 0 in which no name is specified
1987 for the construction. The macros odr_implicit and odr_explicit sets name
1988 parameter to zero for the construction involved. New macros
1989 odr_implicit_tag and odr_explicit_tag are similar to the others,
1990 except that a name parameter is added. For programmers' that don't use
1991 ODR they probably only need to change the call to z_APDU and z_External.
1993 Added access control facility by interfacing the TCP wrapper library.
1994 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1995 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1996 name of the daemon and enables the access control as specified in
1997 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1999 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2000 den Dool <H.M.vdnDool@kub.nl>.
2002 Added reference ID parameter to most functions in server API - refer
2003 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2005 Changed name of ccl library to libccl.a (was ccl.a).
2007 Fixed bug in decoder for Explain (Category TargetInfo).
2009 Added support for GNU readline in client. Thanks to Jacob Poulsen
2010 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2012 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2013 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2014 IMPLEMENTATION! This change was made to the development version before
2015 the ZIG decided to retract the amendment. If any users MUST be
2016 compatible with the original Update definition, PLEASE CONTACT US, and
2017 we will include a separate definition corresponding to the old Update
2018 ES. Note that because of the change to the ASN.1 of the
2019 TaskPackageRecordStructure we cannot define a single structure that
2020 will support both versions.
2022 * Added const modifier to buffer parameter for some ODR/BER encoding
2023 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2024 completeWAIS, odr_dumpBER.
2026 Fixed bug in client.c which caused a crash when a scanResponse didn't
2027 contain positionOfTerm.
2029 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2030 * will cause an error in a client if a non-YAZ target sends both a
2031 * list of Scan entries and non-surrogate diagnostics.
2033 Retrieval module enhancements. Tag sets may be typed in the reference
2034 to it. From the .abs-file the "tagset" directive takes a third optional
2035 integer type for the tag set referenced. From a .tag-file the "include"
2036 directive takes a third optional type as well. The old "type" directive
2037 in the tag set itself is still recognized but acts as the default type
2040 Backend interface change. Individual Scan terms returned from bend_scan
2041 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2042 in include/backend.h.
2044 Retrieval module enhancements. Multiple tag sets and attribute sets may
2045 be specified in abstract syntax specs. Revised the error/warning for
2046 logging messages reported by the retrieval module when reading the
2049 Object Identifier system (oid_..) changed. The API is backwards
2050 compatible but the oid-routines now allocates new OID's when needed.
2051 Raw OID's may be specified in oid_getvalbyname.
2053 YAZ now uses GNU configure to generate Makefile(s).
2055 * Minor changes in some of the member names of DeleteResultSetRequest and
2056 DeleteResultSetResponse. See include/proto.h.
2058 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2059 and added member 'languages' in TargetInfo (which was missing).
2061 Changed the way attribute sets are handled in the retrieval
2062 module. These are now cached, just like the abstract syntaxes
2065 Changed YAZ so that it links with compiled ASN.1.
2067 Added Explain-schema definitions and mapping routines. The following
2068 Explain categories have been implemented: AttributeDetails,
2069 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2071 Fixed minor bug in Windows version of Server Library.
2073 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2075 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2077 Added EXTERNAL: UNIverse Resource Report (non-standard).
2079 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2080 ENUMERATED and SET OF.
2082 * Added 'const' to some of the char pointer arguments for the
2083 functions, data1_read_node, data1_getelementbytagname,
2084 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2087 Fixed bug in data1_insert_taggeddata - the last_child member of
2088 parent wasn't initialised.
2090 * Changed data1_read_record and data1_read_node so that the supplied
2091 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2092 doesn't refer to any parts of the "SGML"-buffer.
2094 Fixed bug in server library (Windows version of statserv_remove).
2096 * Changed code so that it compiles as C++. The type definition
2097 of Odr_fun which is a member of Odr_arm was changed. The result is,
2098 that an explicit typecast is needed for the fun pointer when
2099 using Odr_arm - as in:
2100 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2102 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2104 Implemented the new structured date and time definition as approved
2105 by the ZIG. Added schemaId element to the specificTag in Espec-1
2106 (also approved at the last ZIG). Thanks to RVDM.
2108 Added some Object identifiers (RVDM).
2110 Changed the Update Extended Service (RVDM).
2112 Added command "refid" to client which specifies referenceId for
2113 the following requests.
2115 Implemented extended service handling for server. See ztest.c
2116 for an example as well as backend.h. New handlers are registerd
2117 in the Init handler.
2119 * Changed interface for sort in server.
2121 Added new members to statserv_options_block. It allows a server
2122 to read options from another source than just the command line. Thanks
2123 to Charles Woodfield.
2125 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2126 renamed to zboolean. Some C++ compilers complained about the name.
2128 Minor changes to gils.abs. Added index 's' (sort) on title
2129 and date/time-last-modified.
2131 --- 1.4pl2 1998/1/30
2133 Fixed bug in server library regarding inetd mode (-i). This bug
2134 was introduced by release 1.4.
2136 --- 1.4pl1 1998/1/29
2138 Added sort facility in client and backend server interface.
2140 Fixed problem with dependencies in Makefile(s).
2142 Fixed bugs for encoders/decoders of extended services and
2145 Implemented sub-tree feature for schemas. Sub-trees are
2146 referenced in *.abs-files. See explain.abs for an example
2147 of the use of this feature.
2149 Modified bib1.att; local attributes for ANY didn't include
2150 ANY itself (only affects use of the retrieval module).
2152 Fixed bug in plain SGML reader in function data1_read_node:
2153 tags with prefix "var" was incorrectly interpreted as variants.
2155 Added feature "sub-schemas" to enable references to - and definitions
2156 of - group of elements.
2158 * Removed member parent from type data1_element (in data1.h).
2160 Implemented function odr_nullval() that returns the value of
2163 * Removed member num_children from data1_node (in data1.h).
2165 Made NT service interface part of the server library. The
2166 function statserv_main uses the NT service when required and
2167 calls the statserv_start / statserv_close routines.
2169 Routine zget_SearchRequest and zget_PresentRequest fills
2170 resultSetName/Id member with "default" instead of "Default".
2172 Fixed memory leak in server. Request queue member wasn't freed.
2174 Fixed nmem_exit so that memory is freed.
2178 Revised the CCL parser utility to be thread safe.
2180 Added function, oid_ent_to_oid, to replace the function
2181 oid_getoidbyent, which is not thread safe.
2183 * Added nmem_init and nmem_exit to initialize and release
2184 NMEM resources. Function nmem_init should be called once in the
2185 initial thread before NMEM/ODR is used. statserv.c and client.c
2186 have been changed accordingly. The change was necessary to make
2187 NMEM thread safe. The NMEM memory pool is shared amongst threads
2188 in a process. Unix-based applications will still work fine without
2191 Added NT Services interface for the the Z39.50 (statserv) Server.
2192 Refer to the ztest.c source on the usage.
2194 Windows 95/NT port using MSVC5.0. Project files are included in the
2197 * Defined new 'global' handle for the retrieval (data1) system. The
2198 new handled, data1_handle, describes the state of the data1 system.
2199 This handle is passed as first argument to virtually all
2200 data1 related routines. The functions data1_create and data1_destroy
2201 creates and destroys a data1 handle respectively.
2203 Added ODR encode stream member to all backend request structures
2204 init, search, scan etc. This stream should be used to allocate all
2205 memory used for the response when thread safe operation is needed.
2207 Changed the comstack utility, cs_addstr, to be thread safe. The
2208 returned hostname string returned by the function is now part the
2211 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2212 function. The cs_straddr takes a COMSTACK handle as argument, so this
2213 function must be used after cs_create and before bind/connect.
2214 This function is thread safe.
2216 Moved test server to 'ztest' directory - generic server code still
2217 in 'server' directory.
2219 Made prefix query (pquery.c) utility thread safe.
2221 Added new function modifier YAZ_EXPORT to 'export' public DLL
2222 functions when using windows (see include/yconfig.h).
2224 Added definitions to the OID database (util/oid.c) (RVDM).
2226 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2228 Added call to ccl_rpn_delete in client program.
2230 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2231 release of RPN structure.
2233 Added support for C++, headers uses extern "C" for public definitions.
2234 With input from RVDM.
2236 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2237 Thanks to Ronald van der Meer (RVDM).
2239 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2241 Added support for private extensions to the OID database
2242 (oid_setprivateoids()). Thanks to RVDM.
2244 Added optional, physical ANY (key replication)
2246 Fixed null-reference problem in GRS-1 output filter.
2248 Proximity operator added to Prefix Query Format (PQF).
2250 In test client command "base" accepts multiple databases.
2252 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2256 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2258 Smallish bug-fixes in the new encoders/decoders (explain).
2260 Bug fixed in DeleteRequest.
2262 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2264 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2266 Added SOIF syntax (using private OID for now) to retrieval module and client.
2268 Added Update extended service.
2270 Added SearchResult-1 additional info structure.
2272 Added optional CCL (ISO8777) interpreter as separate module. Available
2275 --- 1.2 1996/6/10 (1st anniversary release)
2277 Added Summary record syntax. Lightly tested.
2279 Added OPAC record syntax. Untested.
2281 Added ResourceReport service encoders/decoders. Untested.
2283 Fixed bug in z_Unit - wrong tagging on unitSystem.
2285 Fixed bug in the DiagRecs decoder.
2287 Added options for max PDU size and session timeout to frontend-server.
2289 Added documentation of query-language parsers and other supporting utilities.
2291 [frontend-server] Added Attribute set to the bend_scanrequest API.
2293 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2294 surrogate diagnostics were generated.
2296 [retrieval] Allow multiple local values for attribute.
2298 [retrieval] Allow multiple attributes per element in .abs files. index type.
2300 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2302 --- 1.1pl2 1996/4/10
2304 Minor changes, mostly specific to Zebra's requirements (retrieval)
2308 Repaired bug in frontend server when running multiple listening
2309 endpoints in dynamic mode.
2311 z_External() now won't break if a known, ASN.1 value comes encapsulated
2312 in an octet-string. The value will pass through unmodified in an Odr_oct.
2314 Added a bit of code to the demo client to decode & display
2315 ASN.1-structured records represented in the octet-aligned branch of
2316 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2318 Added z_ext_getentbyref() to the ASN module. Doc updated.
2320 * Completed the SCAN definition in the ASN module. This may break SCAN
2321 code based on older YAZ-versions at compile-time. The fix is easy -
2324 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2325 under the SCAN definition. Remember to initialize this, server-people.
2327 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2328 that this does not extend to ODR and ASN.
2330 Comstack allows insertion of established socket (primarily for
2331 inetd-operation of servers). Doc updated.
2333 Front-end server can now start from the inetd in TCP mode. Doc
2336 --- 1.0pl4 1996/1/24
2340 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2341 the rank and record number.
2343 Adjustments to the frontend server.
2345 Fixed diagnostic BER dumper. It ignored the file argument.
2349 Various changes to retrieval module.
2351 Changed the union discriminators of the protocol files from enums to
2352 ints paired with #defines.
2354 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2357 *Changed operator in the RPN structure to 'roperator', again to avoid a
2360 Fixed problems in Explain decoders/encoders.
2362 --- 1.0pl2 1995/12/6
2364 Memory bug in log module fixed.
2366 --- 1.0pl1 1995/12/5
2368 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2370 Bug in Explain DatabaseInfo module fixed.
2372 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2376 The shift to v1.0 signals that we now consider the *core* functionality
2377 of YAZ reasonably stable (the core being more or less equivalent to
2378 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2379 tested (Explain not at all - though that will happen soonish).
2381 Minor changes to code to support Windows port.
2383 Various minor changes after we're getting to use GRS-1 & co. more.
2385 Added Espec-1 format.
2387 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2388 of the protocol and it cannot be selected when encoding (maps into 'string'
2389 when decoding). Needed to talk to some servers.
2391 Demo client can request simple element set names.
2393 Added Diagnostic Format encoders/decoders.
2395 Added simple Close handling to frontend server (no hooks for resource
2396 reporting yet), and demonstration client.
2398 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2400 --- 1.0b3 1995/08/24
2402 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2403 handled incorrectly when records were requested in the searchResponse. This
2404 will only affect you if you use the frontend-server.
2406 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2407 Test-client will ask for and print GRS1. Ztest will return dummy records
2410 Added Explain encoders/decoders to the service-level API. Untested.
2412 Added Extended Services: Item Order encoders and decoders to the Service-
2413 level API. Untested. We could use a recent copy of the pertinent bits
2414 of the ILL protocol to add those bits.
2416 Added diagnostic format 1 encoders/decoders to the service-level API.
2419 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2420 odr_cons.c, which causes a more correct output.
2422 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2423 was always set to 0 when no records were requested in the searchRequest.
2425 * Added better external-handling. This shouldn't harm old code that
2426 *encodes* externals. It can break code that looks for a
2427 'single-ASN1-type' representation, since those types that are known
2428 are now decoded immediately. Look at the SUTRS sample code in
2429 seshigh.c and client.c. Documentation updated.
2431 Handling of structured records in bend_fetchresponse. Length -1 marks
2432 structured record, type is deduced from format field.
2434 --- 1.0b2 1995/06/27
2435 Fairly quick maintenance release to add SUTRS support.
2437 Fixed handling of SUTRS records in the demonstration client.
2439 * Added format field to the bend_fetchrequest and bend_fetchresponce
2440 structures of the backend API (frontend server). When the record is
2441 returned, the value of the format field is mapped to an OID. The
2442 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2443 of the record. The special value VAL_NONE in the bend_request means
2444 that no specific format was requested by the client. Documentation
2445 updated accordingly. Test server (ztest) will return a fixed dummy
2446 SUTRS record if your client requests SUTRS.
2448 Documentation updated accordingly.
2450 You can now set external libraries and RANLIB support in the top-level
2454 First public release.
