1 Added support for ISO5426 to UTF-8 conversion.
5 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
6 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
8 ZOOM C now interprets databaseName option for ZOOM connection as path
11 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
13 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
15 Dummy Libxml2 types no longer defined in headers of YAZ'.
17 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
22 Various ODR chapter fixes.
24 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
26 Added missing source for Windows compilation, mutex.c.
28 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
30 For SRU connections in ZOOM all records up to "count" are now fetched.
32 Fixed crash in generic frontend server (and yaz-ztest) which occurred
33 in Windows due to bad error handling for Libxml2.
35 Added facility for sending arbitrary records (ASN.1 any) using
36 ZOOM C's Extended service update. Patch by Sam Reynolds.
38 New options for ZOOM C's connection, logapdu which makes ZOOM log
43 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
47 Fixed memory violation that could occur when decoding UTF-8. This bug
48 was only present in 3.0.30 of YAZ.
52 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
53 GNU TLS is used by default (if found).
55 yaz-ztest returns OPAC records if a client asks for OPAC.
57 Improved speed of MARC-8 encoding.
59 Added support for lossy and loss-less MARC-8 encoding.
61 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
63 Added new Windows Service wrapper (sc).
65 yaz-client's itemorder command may now send a file.
67 Fixed yaz-marcdump to allow the use of NS prefix for record element.
69 Added new function yaz_log_xml_errors.
71 Allow (but warn) unknown XML attributes in MARCXML parsing.
73 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
75 The UTF-8 to MARC-8 conversion now uses a different set of characters
76 for Greek symbols. Bug #2120.
80 Added yaz_daemon (daemon.h).
82 Fixed bug #2068: pkg-config trouble
84 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
88 Document --with-xml2 option.
90 Added OPAC XML XSD (etc/opacxml.xsd).
92 Allow glob mask for name attribute in retrieval element for the
93 generic frontend server's retrieval facility.
95 Changed yaz_poll_poll to return yaz_poll_except for all returned events
96 except POLLIN/POLLOUT.
98 Fixed error handling in cs_listen. Bug #2037.
100 --- 3.0.22 2008/01/20
102 Fixed version in yaz/yaz-version.h.
104 Fixed bug #2027: Crash when closing connection.
106 Changed configure so that ICU support is only enabled if only ICU
107 and Libxml2 is available (because the ICU chain is XML based).
109 --- 3.0.20 2008/01/15
111 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
112 is built. Only this DLL depends on the ICU runtime.
114 yaz-ziffy is no longer part of YAZ. It is distributed separately by
115 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
117 Changed license of CCL module to 'Revised BSD'. After consultation with
118 remaining members of the original EUROPAGATE consortium, we are re-issuing
119 the CCL module without a separate license. The software was developed by
120 Index Data as part of a research project. The special license was included
121 to help feed usage information back to the project consortium to support
122 project evaluation. At this time, the project consortium has long-since
123 disbanded, and the majority of the original principals have retired. At the
124 same time, we have significantly modified the software during the following
125 years, to the point where very practically no original code remains. To
126 simplify re-use of the software, we have contacted those members of the
127 consortium who could be reached, and agreed to re-issue the module as a
128 proper part of the YAZ package.
130 Tcl scripts uses /usr/bin/tclsh as preferred shell.
132 CQL closer to being version 1.2 compliant. CQL also allows free-form
133 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
136 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
137 bug could make Extended services handling crash in the ZOOM layer. This
138 bug was only present in YAZ 3.0.18.
140 --- 3.0.18 2007/12/19
142 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
145 yaz-marcdump reads and writes collection wrapped records.
147 Handle OPAC for record conversion module.
149 Fixes for ICU wrapper.
151 Allow ICU libs to be controlled with --with-icu .
153 --- 3.0.16 2007/11/12
155 Added yaz_poll which is a wrapper for select/poll. When poll is available
156 and non-buggy, it is used, by yaz_poll . This allows more than 1024
157 sockets to be in use.
159 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
160 functionality through an XML based configuration (ICU chain). This system
161 is useful for search facilities such as Pazpar2 and Zebra that needs to
162 perform tokenization of indexed material. The ICU code in a separate
163 library libyaz3_icu.a.
165 Added HTTP tunnel facility for COMSTACK, bug #1752.
166 This is a facility that allows a Web proxy, such as squid, to tunnel
167 Z39.50 traffic. This facility is "transparent" to must applications
168 using YAZ. It's enabled by using pseudo transport connect: followed by
169 the proxy address, followed by command, then follwed by he regular
170 "virtual" addresss. For example,
171 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
173 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
175 --- 3.0.14 2007/09/21
177 Fixed bad memory reference in ZOOM_record - cuased by member not being
178 initialized. This was a problem only in YAZ 3.0.12.
180 Fixed bug in conversion from MARC to XML: Non-XML characters in control
181 fields were not removed.
183 Changed the way C code is generated from codetables.xml. Made a MARC-8
184 conversion trie for each characterSet section rather than codeTable.
185 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
186 of codetables.xml from Larry Dixson, LOC. Bug #1464.
188 --- 3.0.12 2007/09/12
190 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
191 from ZOOM_record_error).
193 ZOOM C function ZOOM_record_get returns record schema for type="schema".
195 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
197 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
199 Better SRW-to-Bib-1 diagnostic mapping.
201 ZOOM C and yaz-client announces SRU version 1.2 by default.
203 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
206 Fixed in yaz_sru_decode to allow other version than 1.1.
208 --- 3.0.10 2007/08/22
210 Added support for SRU scan for ZOOM.
212 Added support for the use of the older versions or Extended Service
213 Update in ZOOM. To faciliate this, an option "updateVersion" may be
214 set to the version , 1=first, 2=second, 3=third. The third version is
215 what ZOOM C has used so far. And that, obviously, is the default.
217 Added support for CCL queries in Z39.50 queries sent to the GFS (and
218 therefore in Zebra and in SimpleServer-based applications). The new
219 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
220 qualifier file used to transform incoming CCL queries into Type-1 RPN,
221 which is passed into the back-end search callback function.
223 Added support for HTTP Basic authentication in clients: the SRU/W
224 codec encodes the username/password elements of the PDU structure
225 appropriately, and these may be set using the "user" and "password"
226 options in ZOOM-C applications (the same options that are used for
227 Z39.50 authentication).
231 Fixed bug #1208: SSL appears to be broken in ZOOM.
233 Fixed bug #1206: Libxml2 include path weirdness.
235 Added oid_name_to_dotstring.
237 Allow elementSetName to be specified for ZOOM C record update.
239 Allow waitAction to be specified for ZOOM C based for Extended Services.
241 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
242 syntax OID. Bug introduced in YAZ 3 series.
244 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
248 Fixed bug #1157: yaz-client does not read .yazclientrc from current
249 directory. yaz-client now reads commands from file given by option -f
250 if specified; then tries to read .yazclientrc in current directory.
251 Failing that, it reads .yazclientrc from user's home directory.
253 Added support for correlationInfo Note and ID for Record Update via
256 Added yaz-client command querycharset which specifies character set for
257 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
258 (termListAndStartPoint).
260 Charset ISO5428:1984 is an alias for ISO5428-1984.
262 Implemented a way to perform scan in a result set using Z39.50. This
263 is achieved by attaching the result set name in the characterInfo
264 (type InternationalString) of OtherInformation in the Scan Request PDU.
265 The result set is identified in the otherinformation by the new OID:
266 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
267 This allows for scan in result set and faceted search . Zebra did some
268 of this in the APT term using attribute type 8 and value being result
269 set. Using the OtherInformation approach for this is cleaner and easier
270 to work with in proxies and the like. This facility can be used in
271 yaz-client using new command setscan which takes a result set as first
272 argument, start position (APT) as second.
274 Changed decoding of SRU XML packed records to deal with servers that
275 have recordData with XML data with multiple root nodes. Also make
276 comparison for recordPacking case insensitive. Again, one server
277 returns "XML" where others return "xml".
279 For SRU responses allow Content-Type application/xml as well as text/xml.
283 Fixed bug in character set conversion of BER strings. Bug introduced
288 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
290 For OID class, use oid_class consistently.
292 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
295 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
296 character set for bibliographic information interchange". By Giannis Kosmas.
298 Added documentation on new OID API.
302 Changes to generic frontend server interface: added new member
303 'query_charset' for bend_initrequest structure. A backend init handler
304 should set this member to its native character set for query terms.
305 When defined, the frontend server logic will announce this character set
306 to a client if the negotiationModel bit is set by the client. All server
307 implementors are encouraged to specify this. If a backend server does not
308 specify this a warning is issued using yaz_log(YLOG_WARN,..).
310 Added CCL utility to remove terms (stop words) from resulting RPN
311 tree. This is handled by functions with prefix ccl_stop_words_ .
313 New ZOOM C option, "rpnCharset", which allows client-side conversion of
314 terms in RPN queries.
316 Clean-up the CCL API. Moved some internal structures from ccl.h to
317 private header cclp.h. Changed ccl_parser_create so that a Bibset must
318 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
319 This is replaced by ccl_parser_find_str which takes a string instead.
321 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
322 libyaz.la is the core of YAZ except the generic frontend server and
323 does not depend on POSIX threads anymore. libyaz_server.la is the
324 generic frontend server facilities and uses POSIX thread functionality
325 if available. The libyaz.la no longer depends on POSIX threads because
326 the number of global structures is limited. NMEM no longer re-uses blocks
327 between threads ; it simply free's memory immediately but allocates in
328 "large" chunks as usual. We don't expect any performance penalties
329 because of this. The yaz_log system is still using a global log_level so
330 caution must be taken when modifying it with yaz_log_init_.. +
331 yaz_log_mask_str. This, however, should not cause any trouble because
332 these functions are called during initialization of application code
333 anyway. `yaz-config --libs server` returns libs for server applications;
334 `yaz-config --libs` returns libs for non-server applications.
336 New OID database - with public definitions in oid_db.h. Removed old OID
337 database including the head oid.h and definitions such as enum oid_value
338 and struct oident. The new OID database uses the same string names as
339 before but the 'protocol' is gone. There are now only two representations
340 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
341 converts from string to OID; functions with prefix yaz_oid_to_string
342 converts the other way.
344 Change to emit_term() in CQL-to-PQF query translation: when a term has
345 the /regexp relation modifier, do not process it for leading and
346 trailing "^" and "*", which have quite different meanings in regular
349 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
350 write handlers no longer carries a 'last' parameter. This will make
351 yaz_iconv flush "less" characters. A flush is performed by call to
352 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
354 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
355 removed, because function yaz_query_to_wrbuf does the same.
357 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
358 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
360 Deprecated MARC utility functions removed.
362 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
365 Branch split: YAZ_2_1_55_branch
367 --- 2.1.54 2007/03/16
369 Fix to ZOOM-C so that transparent reconnection is properly handled on
370 connections that are in asynchronous mode.
372 Fixed compilation on OpenBSD 4.0.
374 Large strings in GRS-1 records are now properly displayed in yaz-client.
376 Added character conversion support for "advancegreek"; based on patch from
379 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
380 sequence is met. Before the error was not set so it would be unknown.
382 Adjust yaz-marcdump MARC reader so that it skips until record separator
385 --- 2.1.52 2007/03/07
387 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
388 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
389 fd_set structure used as a bitmask for the FDs to be selected on.
391 Using ACX_PTHREAD macro to check for POSIX threads.
393 Fixed have-vsnprintf check.
395 --- 2.1.50 2007/02/23
397 Fixes for configure on BSD. Bug #900.
399 Added snprintf/vsnprintf wrappers for systems that don't have
400 limits (heavens forbid).
402 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
403 created before all previous tasks were completed and removed from the
404 task queue, the new task could be removed by a mistake.
406 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
408 Implemented pass-through CQL-to-PQF conversions. Bug #861.
410 Fixed bug #832: Problem with MARC/charset in yaz-client.
412 Fixed bug #668: save command line history for yaz-client.
414 Fixed bug #830: pkg-config support.
416 --- 2.1.48 2007/01/23
418 Extended ZOOM result set options with two options that may be read by
419 a client: resultSetStatus and presentStatus with values as specified for
421 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
423 Fixed bug #827: Using SSL fails on Debian etch.
425 Fixed bug #826: Weird looking chars for set of MARC records.
427 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
428 that is treated as an ItemOrder with itemRequest being an XML document
429 external. The value of "doc" is the content.
431 Extended the GFS search facility. New member of bend_search_rr
432 'estimated_hit_count' signals that hits is known to be an estmate
433 (higher or lower than real hit count). New member 'partial_resultset'
434 signals that the search was partial (hit count is lower or equal than
435 real hit count). For Z39.50, the information is stored in resultSetStatus
436 member of SearchResponse APDU. For SRU, the information is signalled
437 via SRU diagnostic 59: "Result set created with valid partial results
440 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
442 --- 2.1.46 2007/01/13
444 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
446 Added ZOOM_connection_peek_event.
448 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
449 the following new functions:
450 ZOOM_event_nonblock, ZOOM_connection_process,
451 ZOOM_connection_get_{socket,mask,timeout},
452 ZOOM_connection_fire_event_{timeout,socket}.
453 The existing blocking event handler, ZOOM_event, is a wrapper for the
454 + blocking ZOOM_event_sys_{poll,select}.
456 Implemented function ccl_xml_config which parses XML version of CCL
457 configuration (bug #798).
459 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
461 Added timings utility (yaz/timing.h)
463 --- 2.1.44 2007/01/03
465 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
468 Fixed bug #779: Rotation of apdu.log fails.
470 Fixed for character set conversions:
471 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
472 Honor G1 set in MARC-8 decoding.
474 --- 2.1.42 2006/12/17
476 Fixed bug #775: char conversion does not handle Alternative UTF-8
479 Implemented function yaz_marc_read_line which parses MARC line format
480 records. There is a wealth of formats out there. So far, this function
481 reads line records produced by yaz_marc_write_line.
483 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
484 more generic and easier to remember(!) options: -i format and -o format
485 which specifies input format and output format respectively - where
486 format is one of "marc", "marcxml", "line", "marcxchange".
488 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
489 does not print anything except warnings for records.
491 For yaz-marcdump, added support for MARC split into files (-s) with a given
494 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
495 spec, at http://www.loc.gov/standards/sru/record-update/
496 This has changed the binary layout of the following structs:
497 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
498 bend_update_rr . Patch by Ko van der Sloot.
500 Added GFS utility function bend_assoc_is_alive which returns 1 if
501 association is still alive (client is connected); 0 otherwise (client
502 closed connection). This allows busy servers to stop working for
505 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
506 been a separate piece of software. This version of ziffy has been modified
507 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
509 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
511 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
512 Client code may now interrogate options such as "init_opt_sort" to
513 find out whether the server claims to support various options.
515 --- 2.1.40 2006/11/27
517 Added utilities yaz_{set,get}_esn to set/get element set name from
520 Removed the build of libyazthread.la. The libyaz.so is the threaded version
521 of YAZ and has been so since YAZ 2.1.10.
523 Implemented ZOOM_record_error which returns error information for
524 record (surrogate diagnostic).
526 --- 2.1.38 2006/10/31
528 Updates for SRU Update by Ko van der Sloot:
529 1. Changed name from "operation" to "action"
530 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
531 versions in the code, marked as 'backward compatible'.
532 3. Added diagnostics for SRU Update.
534 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
536 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
538 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
540 For GFS, fixed problem with SRU diagnostic 'First record position out of
541 range' being issued for 0 hits.
543 zoomtst10 part of Windows Build.
545 --- 2.1.36 2006/10/13
547 Implemented yaz_filepath_comp which splits a path into file path
548 components (required by Zebra 2.0.3+).
550 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
551 BSD inspired license until now so this should not have any real impact on
552 anybody. See http://www.opensource.org/licenses/bsd-license.php
554 Fixed bug #687: Missing log lines.
556 Fixed bug #678: CQL to PQF translation does not preserve double-quote
559 Fixed bug #689: SRU diagnostics to be added.
561 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
562 whether a connection is idle (no more work do do).
564 --- 2.1.34 2006/10/04
566 Change type of optval from long to int for invocation of setsockopt with
567 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
569 Added support for specifying the max log file size for the Generic
570 Frontend Server. The size is given with option -r.
572 --- 2.1.32 2006/09/21
574 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
576 --- 2.1.30 2006/09/17
578 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
581 Fixed bug in Generic Frontend Server that could cause a server to stop
582 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
584 For the generic frontend server, the maximum record size is used as maximum
585 size of incoming packages (SRU + Z39.50). The value until was previously
586 only used in Z39.50 Init negotiation and, later, in a session controlled
587 sizes of records returned. This is controlled using -k option. It can be
588 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
590 --- 2.1.28 2006/09/04
592 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
595 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
597 New option for yaz-marcdump -lpos=value which allows setting a portion
598 of MARC header to a certain value.
600 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
602 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
603 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
605 --- 2.1.26 2006/08/15
607 Fixed problem with SRU mode type (soap, get, post) for yaz-client
610 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
612 --- 2.1.24 2006/08/08
614 Fixed MARC ISO2709 encoding routines to deal with character set
617 Minor changes to GFS logging. Database included in search request log
620 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
621 cached/multiple records.
623 Shared libraries are built by default on Unix+configure.
625 Changed cql2pqf transformation to use a different evaluation order. The
626 new order is: always, relation, structure, position, truncation, index
627 and relationModifier. Old order was: always, relation, relationModifier,
628 structure, index, position, truncation. Note that the the latter ones
629 override former ones for identical attributes.. The new scheme means that
630 it is possible to override any existing attribute with a relationModifier.
631 And also that it is possible to override everything for the index rule
632 (except the ones listed in relationModifier). No order is perfect but this
633 one, we believe, covers more real cases.. The "always" should have been
634 called "default", since the attributes there can be overridden with all
637 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
638 compilation phase, but also for yaz-config --cflags output. This allows
639 us to have public headers with Libxml2 stuff in them . It should also,
640 eventually, make Libxml2 checks redundant in packages using YAZ, such
643 --- 2.1.22 2006/06/15
645 Changed SRU update structure bend_update_rr so that SRU diagnostics are
646 stored in uri, message and details.. Previously diagnostics were stored
647 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
648 compatibility.. but he's probably the only one affected, so.
650 Added support for CCL, compiled on the client side, in ZOOM-C. This
651 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
652 input; the resulting query objects can be used for for searching with
653 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
655 YAZ' configure searches for OpenSSL by default.
657 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
658 SL_CTX_use_certificate_file. See
659 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
660 for more info. Thanks to Ko van der Sloot.
662 --- 2.1.20 2006/06/02
664 Bug #600: SRU GET, POST support for yaz-client. Introduced
665 command 'sru' which selects method SOAP/GET/POST.
667 Allow missingValueAction to be specified for the sortspec string -
668 function yaz_sort_spec. By default, the missing value action is null.
669 Use ! to specify "abort". Use = followed by stringvalue to specify default
672 Ensured that Present-handler (if defined) is called in GFS before any call to
673 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
674 searchRetrieve requests.
676 Documentation for YAZ is now based on the Docbook XML/XSLT using
677 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
678 is no longer depending on jade/openjade or docbook-to-man scripts.
679 PDF is no longer part of the distribution - but can optionally be
680 made using DSSSL/jadetex or FOP.
682 Added retrieval handling support in Generic Frontend Server to support
683 conversion between MARC/XML as well as XSLTtransforms. See
684 etc/yazgfs.xml for an example.
686 Added Authentication support to Generic Frontend Server in SRU
687 mode. Authentication using HTTP Basic is supported, as is the use
688 of 'x-username' and 'x-password' parameters in the request itself.
690 Added support for a new character set MARC8s identical to MARC8 except
691 that it converts combined characters to single Unicode characters in the
692 Latin-1 range (when possible).
694 --- 2.1.18 2006/04/24
696 ASN.1 compiler 0.4: generates brief Doxygen file header for
697 generated .h/.c files.
699 Utility yaz_iconv now supports conversion to MARC-8.
701 New facilities for the MARC module. The reading - and writing of
702 content are separate methods for the yaz_marc_t handle. The following
703 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
704 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
705 format). Write functions have prefix yaz_marc_write_.. The existing
706 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
707 available. Removed support for OAI-MARC and simplexml (not the
708 simplexml from PHP5).
710 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
711 to be returned for this connection.
713 --- 2.1.16 2006/03/31
715 Allow multiple languages and charsets to be specified with
716 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
717 negcharset iso-8859-1,utf-8
719 Translation of proximity nodes from CQL into PQF now works.
721 Moved to automake 1.8, 1.9.
723 Added function yaz_log_set_handler which allows a log handler to be
724 installed. This handler will be called for all log messages. Output
725 to file is also produced; but that can be disabled by passing NULL
726 fname to yaz_log_init_file.
728 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
730 For SRW (including GFS), accept application/soap+xml as content-type
733 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
734 produces NO stylesheet reference even if a default stylesheet is specified
737 --- 2.1.14 2006/03/14
739 Updated Windows package to include yazd.dll + yazd.lib for the
740 Development component.
742 If the environment variable YAZ_LOG is set, then it is used as a
743 string indicating the default level of logging to use if not
744 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
745 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
746 used as before. So, for example, to omit warnings from YAZ logging,
749 cql_transform() now map structure and other attributes before indexes,
750 so that index-specific structures and other attributes can override
751 defaults. So now a combination of mapping specifications such as:
753 index.dc.date = 1=date-modified 4=5
754 does the right thing.
756 cql_transform() now also respects the "always" mapping specification,
757 which establishes an initial set of attributes to be used for all
758 terms except where overridden by more specific attributes associated
759 with the index, relation or modifier.
761 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
762 which mode to use; one of "post", "get" or "soap" (SRW, default).
764 Fixes for yaz_iconv routines: changed trie-based character set conversions
765 to use only non-negative values for bit fields due to Sun's C compiler not
766 supporting negative values.
768 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
769 sequences where not read correctly. Fix by Rustam Usmanov.
771 Updated win/makefile to use options, settings which makes things
772 compile with VS C 2005.
774 --- 2.1.12 2006/02/01
776 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
778 In ZOOM socket code, use select instead of poll on MacOSX.
780 ZOOM-C now support client-side compilation of CQL into RPN that is
781 sent to the server, enabling CQL to be used against all Z39.50
782 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
783 ZOOM_query object, and submit it using ZOOM_connection_search().
784 The CQL-to-RPN translation uses a configuration file, the name of
785 which must be specified in the Connection's "cqlfile" option.
787 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
788 function, which takes as its start-term parameter a ZOOM_query object
789 (which may have had either CQL or RPN set into it).
792 --- 2.1.10 2005/11/29
794 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
795 GFS to support this as well. Backend handler, bend_srw_update, does the
796 update work. Code contributed by Ko van der Sloot.
798 Allow retrieval of Search Result-1 information in ZOOM by the use of
799 options that are attached to a result set. ZOOM documentation updated
802 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
803 UTF-8 conversion. Patch by Raj Patel.
805 Added option -m to GFS to control formatting of timestamps in log file.
807 Added 'exit' as synonym for 'quit' in yaz-client
809 Added support for specifying SRW resultSetId + resultSetIdleTime in a
810 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
811 for the new members. Patch by Ko van der Sloot.
813 Added support for SRU POST. It is supported for content-type
814 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
816 Do not build the separate Multi-threaded (MT) library libyazthread.la.
817 Instead make the library libyaz.la multi-threaded. Threading as a whole
818 can still be disabled by configure option --disable-threads. Previosly,
819 with older GLIBCs there were problems with MT libs under Apache. This
820 has now been fixed a long time ago.
822 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
825 CQL module modified to be case insensitive for relations/indexes/operations.
827 Fixed bug in CQL transform code: incorrect value relationModifieder
830 Added 'show all' command for yaz-client which retrieves all results
833 Added new yaz-client, xmles, which takes a (private) OID and
834 a document to be sent as an extended service request.
836 Describe new yaz-client commands wait_response and set_auto_wait.
838 Increase TCP/IP listener backlog from 3 (which I am guessing was
839 copied from the SunOS manual entry way back when) so SOMAXCONN, so
840 that the socket will queue as many incoming connections as it's able
841 to handle ongoing connections. In other words, it will never now
842 refuse a connection that it would be able to handle merely because
843 it's not got around to accepting() enough of the pending connections
844 yet. This is the behaviour anyway under Linux, where the listen()
845 argument is ignored; but not under BSD and on systems such as
846 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
847 YAZ-based servers should now be uniform across operating systems in
850 yaz-marcdump uses 64-bit file access on some systems. This is enabled
851 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
852 This allows yaz-marcdump to read large MARC batches (>2 GB).
854 Modified all YAZ source files - except the source which is auto-generated
855 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
858 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
859 corresponding to the existing *_setl() function. These allow option
860 values containing arbitrary valuues.
862 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
863 ZOOM_resultset_sort() in new applications. Its behaviour is identical
864 except that it returns an indicator of whether or not the sort
865 criterion was accepted (0 for OK, -1 for invalid).
869 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
870 MARC output rather than returning "new" buffer.
872 yaz-client warns about unknown init options.
874 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
878 Added support for SRW sort in Generic Frontend Server. Patch
879 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
880 sortKeys - or NULL if none is provided.
882 Fixed bug #307: It was impossible to specify indefinite/no timeout
883 for ZOOM_event. Special timeout value -1 now means indefinite timeout
886 Added support for multiple languages and charsets to be specified in
887 ZOOM. Each charset/language is separated by a blank. If negotiation is
888 in effect in init-response, Option
889 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
890 Code based on patch by Vasiliy Osadchuk.
892 Fixed bug #306: infinite recursion that occurred when calling
893 yaz_log_level_init as the first call (before other log level or
896 Fixed bug in scan handling in front end server: if preferred-Position-In-
897 Response was non-present, a NULL pointer referece was performed.
901 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
902 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
903 now defined for all those error codes. So instead of putting 109 in
904 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
905 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
907 Modified the yaz-marcdump utility to skip garbage bytes between MARC
910 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
912 Program yaz-client now exits and produces an error message if multiple
913 Z39.50 servers are specified on the command line (none or one allowed
916 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
921 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
923 Fixed bug #272: Preserve spacing for CCL terms.
927 Added support for virtual hosts and multiple backend servers for
928 the YAZ frontend server. The configution is XML based and
929 support specificition of CQL to RPN mappings and explain information.
930 See section "Virtual Hosts" in the YAZ manual.
932 Extended OPAC display utility. OPAC display utility renders
933 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
934 to supplement yaz_marc_decode_wrbuf.
936 Fixed a bug in MARC decoder that could caused it to crash for some
937 invalid MARC records. More diagnostics and warnings where added in
938 XML output (warnings, etc are stored in comments).
940 --- 2.0.34 2005/02/08
942 Fixes for UNIX domain sockets. Bug #261.
944 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
946 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
947 Added yaz_marc_subfield_str which defines subfield lead string which is
948 used in YAZ_MARC_LINE format. Default string is blank+$. Added
949 yaz_marc_endline_str which defines end of fields string used in
950 YAZ_MARC_LINE format. Default string is newline.
952 Experimental support for MarcXChange. This format can be produced
953 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
954 http://www.bs.dk/standards/MarcXchange.xsd
956 Added yaz-client commands scansize that sets maximum number of
957 entries to be returned by scan.
959 --- 2.0.32 2005/01/11
961 Added support for SRW scan in yaz-client and Generic Frontend Server.
963 * Added whereInList member to SRW Scan Term.
965 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
967 Fixed NMEM system to return aligned blocks on the smallest boundaries
968 that are suitably aligned for all possible types on the particular
969 architecture YAZ is being built for.
971 --- 2.0.30 2005/01/04
973 Fixed numerious warnings that was issued with newer versions of GCC.
975 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
976 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
979 Make YAZ Generic Frontend Server slightly faster.
981 Enhance (and reduce) logging for Generic Frontend Server.
983 Revert YAZ log system so that it flushes every write operation
984 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
986 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
987 instead of LOG_, due to name clash with syslog(3). LOG_ are still
988 present. New applications should define YAZ_USE_NEW_LOG=1 - this
989 will effectively disable old definitions.
991 --- 2.0.28 2004/11/09
993 Added yaz_log_time_format which specifies log format using
996 Added yaz_log_module_level which returns mask for a module. Value
997 is non-zero mask a if module is enabled; zero if disabled.
999 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1000 in include/yaz/cql.h.
1002 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1004 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1006 Fixed bug #172: RPM builds does not enable SSL.
1008 Doxyfile.in part of dist. Doxyfile generated by configure.
1010 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1011 are given and the corresponding component does not exist.
1013 Extend CCL documentation in YAZ reference. Describe r=r.
1015 --- 2.0.26 2004/10/01
1017 Fixed MARC->MARCXML conversion to properly deal with
1018 fields, subfields, indicators having non-ASCII characters.
1020 Fixed MARC->MARCXML conversion so that ASCII control characters
1021 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1024 Added YAZ GFS support for conversion from Z39.50 surrogate
1025 diagnostics to SRW surrogate diagnostics.
1027 Bug fix: YAZ GFS did not return schema in explainResponse.
1029 --- 2.0.25 2004/09/30
1031 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1032 now converts recordSchema to elementSetName as well as schema URI.
1034 Fixed bug in COMSTACK that prevented HTTP request packages from being
1037 --- 2.0.24 2004/09/29
1039 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1040 does not require white-space before and after the dash in a range, e.g.
1041 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1044 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1045 due to new GCC removing "redundant" code.
1047 Added yaz-client commands scanpos and scanstep that sets preferred
1048 position and step-size for scan.
1050 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1052 Added CCL utility ccl_qual_buf which parses one or more CCL
1053 spec lines in a buffer.
1055 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1056 of name and value - ignoring empty lines and comments.
1058 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1060 Added odr_get_element_path which returns current element path for an
1061 ODR handle. This utility is useful in error handling or user-defined
1064 Added ODR_PRINT utility odr_set_stream which is is a more generic
1065 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1066 to a write function and pointer to close function. The close function - if
1067 non-NULL - will be called during odr_destroy.
1069 Fixed bug in CCL parser where truncation char was not removed from
1070 right side when truncation=both was in effect.
1072 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1075 --- 2.0.23 2004/08/11
1077 Fix buffer overrun in CQL parser when dealing with proximity (%).
1079 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1080 to UTF-8/UCS conversion is now only based on codetables.xml.
1082 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1084 --- 2.0.22 2004/08/06
1086 Add support for more "commit changes" in ZOOM (uses Extended Services).
1088 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1091 Yet another small fix for configure of SSL.
1093 --- 2.0.21 2004/05/14
1095 Fix SSL libs for configure when --with-openssl=DIR is given.
1097 --- 2.0.20 2004/05/10
1099 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1101 SSL comstack now uses yaz.pem certificate file on server side
1102 by default. Certificate filename can be configured by calling
1103 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1105 Fix bug regarding multiple calls to ZOOM_connection_connect.
1107 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1109 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1110 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1112 ZOOM now allows inspection of X509 peer certificate for verification.
1113 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1115 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1116 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1117 as "modular" but it simplifies things.
1119 Added cs_get_peer_certificate to that returns peer X509 PEM.
1121 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1122 NULL if SSL is unavailable.
1124 Documentation about MARC decoding tools.
1126 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1128 --- 2.0.19 2004/03/30
1130 Rename CHANGELOG to NEWS to follow GNU style packing.
1132 Fix bug with missing initialization of member in init_diagnostics.
1133 This bug affects threaded version of GFS server.
1135 --- 2.0.18 2004/03/20
1137 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1140 Ensure zlib.dll is packed with Windows install.
1142 --- 2.0.17 2004/03/17
1144 Fix encoding of xsd:string to use text instead of CDATA.
1146 Fix endless loop in CQL parser with unbalanced ".
1148 Use a more compact way to store MARC-8 conversion tables.
1150 --- 2.0.16 2004/03/16 Debian only
1152 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1155 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1160 --- 2.0.15 2004/03/01
1162 Another fix for decoding of XML packed records.
1164 --- 2.0.14 2004/02/25
1166 Fixes for Chunked encoding. White space not ignored after length spec.
1168 Update NS and use default NS for SRW diagnostic elements.
1170 --- 2.0.13 2004/02/23
1172 Implement ZOOM_resultset_cache_reset which resets record cache.
1174 Implement ZOOM_resultset_sort which sorts a result set.
1176 Implement chunked HTTP transfer.
1178 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1180 --- 2.0.12 2004/02/16
1182 Added member 'schema' to bend_explain_rr structure so that backend
1183 can specify explain record identifier. Defaults to Zeerex 2.0.
1185 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1187 --- 2.0.11 2004/02/16
1189 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1192 Added init command for yaz-client which sends "extra" init request.
1194 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1195 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1197 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1199 Make ZOOM error code for "invalid query".
1201 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1203 --- 2.0.10 2004/02/05
1205 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1208 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1210 Added option -p <file> to make Generic Frontend Server to write PID file.
1212 Added option -D to put Generic Frontend Server in background on its own.
1214 Make ZOOM C recognize option "password". If unset, "pass" is used
1215 (for backwards compatibility).
1217 Fixed a bug in Generic Frontend Server that could make it crash if a
1218 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1221 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1222 Must be issued before open, in order to be in effect.
1224 --- 2.0.9-6 2004/01/12 Debian/Windows
1226 Make the SRU server more picky WRT unknown params, etc.
1228 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1230 New YAZ client command, options, that sets Z39.50 options.
1232 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1233 options from a string of tokens (one token for each option bit).
1235 Update SRW diagnostic code messages.
1237 --- 2.0.9-5 2004/01/07 Debian/Windows
1239 Handle user defined stylesheet for SRW/SRU.
1241 --- 2.0.9-4 2004/01/06 Debian/Windows
1243 Fix bug in decoding of Content-Length.
1245 --- 2.0.9-3 2004/01/06 Debian/Windows
1247 Fix a bug with decoding of XML packed records.
1249 --- 2.0.9-2 2004/01/05 Debian only
1251 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1253 Fix bug in SRW/SRU diagnostics decoding.
1255 --- 2.0.9 2004/01/05
1257 Fixed bug in Generic Frontend Server which could drop records exceeding
1258 preferred message size. Reported and fixed by Irina Dijour.
1260 Fixed calculation of package size for structured records in Generic
1261 Frontend Server. Reported and fixed by Irina Dijour.
1263 Fixed namespace for SRW/SRU diagnostics.
1265 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1267 --- 2.0.8 2003/12/22
1269 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1270 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1273 CQL changes to reflect recent changes to the specification:
1274 * Documentation talks about context sets instead of index sets.
1275 * Documentation talks about indexes instead of qualifiers.
1276 * The CQL-to-PQF transformer's configuration file now uses
1277 "index.set.name = <attributes>" instead of the old form
1278 "qualifier.set.name = <attributes>". (Both forms are still
1279 understood but the latter is deprecated.)
1280 * CQL terms with no explicit index specified are now interpreted as
1281 cql.serverChoice instead of srw.serverChoice (which of course
1282 behaves exactly the same.)
1284 --- 2.0.7 2003/12/16
1286 MARC conversion can now generate ISO2709 output in another
1287 character set. yaz-marcdump uses this facility if you invoke it
1290 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1291 functions from there can be used from C++.
1293 --- 2.0.6 2003/12/04
1295 Frontend server now transfers memory from decoded packages to stream
1298 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1299 references to show up.
1301 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1302 the ZOOM Abstract API. The older names for the same options are still
1303 also supported for the benefit of old applications.
1305 ZOOM-C supports "implementationId" and "implementationVersion" options
1306 to go along with "implementationName". These allow the user code to
1307 specify identification strings to be sent to servers.
1308 Add OID for the new ExtLite attribute set.
1310 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1311 as requested/supplid by Ere Maijala <ere@atp.fi>
1313 For generic frontend server, reverse the order of
1314 "toolkit-supplied / application-supplied" strings sent as implementationId,
1315 Name and Version. Also, remove the spaces around the slash. This brings
1316 the GFS in line with the behaviour of ZOOM-C on the client side.
1318 Add function ZOOM_scanset_display_term.
1320 yaz-client shows scan displayTerm if present.
1322 Utility yaz-iconv is now installed by default along with the man page
1325 Extend configure check for OpenSSL to use pkg-config where available (such
1328 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1329 server to specify uid/gid/mask for socket using the format
1330 unix:[user=uid,][group=gid,][umask=mask,]file=path
1331 If file= is omitted the existing format is assumed, e.g.
1333 in which case the mask is 0666 (rw for everybody).
1335 Major restructure of YAZ source. All source in libyaz is in src directory.
1336 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1337 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1339 Added man page for utility yaz-marcdump (used to be called marcdump).
1340 yaz-marcdump is installed by 'make install'.
1342 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1343 of incoming package failed.
1345 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1347 Change prototype of odr_perror: add const to message string.
1349 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1351 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1352 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1353 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1354 DNS lookup. There should not be any compatibility problems with this
1355 assuming that blocking=1 or 0 is used.
1357 Fix bad reference in UNIX comstack in function cs_addrstr.
1359 Fix for compilation on AIX.
1361 The generic front-end server (server/seshigh.c) now supports returning
1362 Init diagnostics to the client in User-information-field, in
1363 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1366 --- 2.0.4 2003/09/04
1368 Allow any CQL relation (not just all,any,exact,scr).
1370 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1371 that features the same UI.
1373 Implemented command update0 in YAZ client which is equivalent to
1374 update but uses old of Ext Update ASN.1.
1376 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1377 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1378 Previously no OID was used for this info.
1380 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1381 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1382 returns 'malformed search term' otherwise.
1384 SortResponse member resultCount now set to NULL in sort handler of
1387 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1390 Add three new utility functions for translating OIDs between various
1391 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1392 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1393 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1394 char *oid_to_dotstring(const int *oid, char *oidbuf);
1395 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1397 Reverted modifications for ES Update definition for z_IU0Update
1398 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1399 is back to YAZ 2.0.2.
1401 String value attributes for CCL parser.
1403 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1404 which their FirstSearch server returns in Init responses, sometimes
1405 carrying useful diagnostic information when Init fails. This has the
1406 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1407 "z39.50/oclcui.asn", where its definition is somewhat different from
1408 what OCLC document on their web-site, as required to interoperate with
1411 Support for anonymous authentication in yaz-client. Use the command
1414 * Fix the OID of the Index Data-local "admin" Extended Service from
1415 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1416 the 1000, which indicates a locally-defined OID, was a mistake.
1418 --- 2.0.3 2003/06/20
1420 Fix CCL directive @case handling so that it affects string match for
1421 both CCL keywords and qualifiers.
1423 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1424 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1425 Decoder has been updated with ASN.1 changes as listed in
1426 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1427 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1428 z_IUUpdate, remains unchanged.
1430 ZOOM_record_get may now return a record in a specific character set.
1431 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1432 "from" is the character set of record as returned by target. "to" is
1433 the character set to be returned. If omitted, "to" is UTF-8.
1435 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1437 New ODR utility, odr_getelement, which returns name of element for
1438 which encoding/decoding failed.
1440 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1441 in cases where a required element was omitted.
1443 Bug fix: some MARC8 sequences were not converted.
1445 New ZOOM option "step" which specifies number of records to be
1446 retrieved in one chunk. Used in conjunction with "start" and "count".
1448 SRW support for yaz-client. Use scheme http: to use it, e.g.
1451 yaz-client no longer does (un)intelligent character set conversions
1452 by default. Can be enabled with charset and marc_charset commands.
1454 xmalloc trace fix for 64-bit systems such as DEC alpha.
1456 Solaris 2.6 compile fix.
1458 New function, cql_strerror() translates SRW error codes, as returned
1459 by cql_transform_error(), into human-readable English strings. Used
1460 in yaz-client diagnostics when appropriate.
1462 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1463 converts it into a type-1 query which is sent to the server. This
1464 makes CQL available for use with all Z-servers, as opposed to the tiny
1465 minority that can handle CQL queries themselves.
1467 --- 2.0.2 2003/04/28
1469 New Debian package layout similar to the Redhat Package layout.
1471 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1472 and search result respectively.
1474 --- 2.0.1 2003/04/25
1476 Redhat package is now several packages: libyaz (runtime libraries),
1477 libyaz-devel (development and documentation, and yaz (utility programs).
1478 Package spec file by Morten Bogeskov.
1480 New member 'schema' in struct bend_fetch_rr which the name of requested
1481 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1482 handler MAY set this to reflect the schema of the returned record.
1484 New member 'display_term' in struct scan_entry. GFS now sets member entries
1485 and allocates scan entries to be filled by user scan handler. In previous
1486 version, entries member was allocated by the scan handler. That still works,
1487 but the GFS will ignore member display_term - assuming it was NOT set by
1488 the handler. The fact that the GFS now allocates the entries both allows
1489 for new members and makes a scan handler easier to write.
1491 Fix CQL lex buffer overflow.
1493 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1494 SRU default recordPacking is string.
1496 SRU protocol support for frontend server.
1498 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1500 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1502 Added scan for the ZOOM shell (zoomsh).
1506 * String Identifers for Schemas (Amendment 5).
1507 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1508 Old definition for schema
1509 Odr_oid *schema; /* OPT */
1514 Z_InternationalString *uri;
1515 #define Z_Schema_oid 1
1516 #define Z_Schema_uri 2
1519 * resultCount parameter to Sort Response (Amendment 1).
1520 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1522 Support for SRW 1.0 over HTTP. This is an optional feature and
1523 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1526 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1527 on the same port. SRW SearchRetrieveRequests are mapped
1528 to bend_init,bend_search,bend_fetch,bend_close.
1530 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1532 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1533 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1535 ZOOM connections are SRW based if schem http is used for hostname
1536 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1537 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1539 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1540 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1541 distance=n, order=true/false, relation=le, prox unit=word. If
1542 n is omitted, distance 1 is used.
1544 Fixed problem with C compiler include path in wrong order.
1546 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1547 on Solaris. Patch from Ko van der Sloot.
1549 New MARC decode API. All new functions operate on a yaz_marc_t
1550 handle. The most important new functions are: yaz_marc_create,
1551 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1552 decode and destroy respectively. Decoder can produce formats
1553 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1554 include/yaz/marcdisp.h.
1556 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1557 to UTF-8, UCS-32, wchar_t or Latin-1.
1559 * Prototypes for yaz_iconv_-functions moved to separate header
1560 include/yaz/yaz-iconv.h.
1562 Make a few private functions 'static' in unix.c. This prevents
1563 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1565 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1566 are set when Init Response is received.
1568 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1569 but returns diagnostic set as well.
1571 New function yaz_strerror which is a portable wrapper for
1572 strerror/strerror_r/GetLastMessage.
1574 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1575 is returned for MARC. If type is "oai", then OAI MARC is returned.
1577 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1580 --- 1.9.2 2002/11/26
1582 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1584 Fix bad race conditions on SIGTERM and terminate gracefully in
1587 Move retrieval (data1) module to Zebra since nobody seems to be
1590 Add GRS-1 render for ZOOM using same format as yaz-client.
1592 --- 1.9.1 2002/10/05
1594 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1596 Fix broken ESpec handling in data1 module.
1598 SGML reader parses comments and makes them part of the data1 tree.
1600 Added several type casts so that YAZ compiles as C++ code.
1602 ZOOM didn't handle PDU encoding failures properly.
1604 Added more Bib-1 diagnostics (approved extensions).
1606 GNU configure: better check for iconv.
1608 More portable use of accept, getpeername. Check for socklen_t. Use
1609 int/size_t if socklen_t is not defined.
1613 PQF parser rejects bad queries - including those with extra
1614 characters in them. PQF parser used to silently ignore that.
1615 Cleaner API for PQF added, which allows you to get detailed
1616 error information for bad queries (see yaz/pquery.h).
1618 Fixed bug in ZOOM_record_get for type "database".
1620 Implemented mini iconv library supporting conversions between
1621 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1623 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1625 --- 1.8.9 2002/08/20
1627 Fixed ZOOM C record cache so that preferredRecordSyntax and
1628 elementSetName is used to check for already fetched records.
1630 --- 1.8.8 2002/08/02
1632 Added three members in bend_initrequest structure to facilitate
1633 character set negotiation.
1635 Fixed a bug in frontend server that could cause indefinite
1636 loops under rare conditions.
1638 Revised character set utilities (charneg.h) so that encoding
1639 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1641 For PQF, directive @term <type> sets term type for Scan/Search.
1642 Here <type> is general, string, numeric, null. The term type
1643 is inherited - just like @attr.
1645 New call odr_set_charset that sets character set conversion for
1646 international-strings on a ODR stream. Prototype is:
1647 int odr_set_charset(ODR o, const char *to, const char *from);
1648 The InternationalString is still represented as C string in YAZ
1649 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1650 won't). On the protocol level, you can use any encoding.
1652 Support for UNIX sockets in ZOOM.
1654 Solaris recv sometimes returns errno == ENOENT. It is treated as
1655 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1657 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1658 both client and server. Code by Morten Bogeskov.
1660 --- 1.8.7 2002/05/22
1662 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1663 that they can be used directly from Visual Basic. You must recompile
1664 your windows APP if you're using ZOOM.
1666 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1667 Commands "lang" and "charset" sets language and character set respectively.
1668 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1669 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1671 Attributes from multiple CCL fields may be OR'ed rather than merged
1672 using directive "@field or". Fields are still merged by default -
1673 equivalent to "@field merge".
1675 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1678 Fixed bug in zget for parameter ExtendedServicesResponse.
1682 --- 1.8.6 2002/03/25
1684 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1686 Client displays USR.1:SearchResult-1 (hits per term).
1688 Additional Search Info for search in Generic Frontend Server.
1690 Fixed CCL parsing of "field=s".
1692 WIN32 installer - using the excellent NSIS software from nullsoft.
1694 Fixed CCL parsing of "field = - <number>".
1696 Added function yaz_marc_decode that decodes MARC for line mode
1697 display or XML (similar to that used by JZKit).
1699 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1700 Z39.50. But ISO/ILL was, however.
1702 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1703 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1705 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1706 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1708 --- 1.8.5 2002/02/03
1710 New YAZ client features: Command completion and new commands:
1711 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1712 Code provided by Jacob Poulsen.
1714 New call oid_trav, that visits all registered OIDs via callback.
1716 Function ZOOM_record_get now returns const char pointer rather than
1717 void pointer. It saves a lot of type casts.
1719 For YAZ client, command "auth" now allows you to set authentication
1720 in IdPass style. It is enabled when three tokens are given - order
1721 is user, group and password.
1723 Fix memory leaks in MARC record handling for ZOOM.
1725 New option for YAZ client, -k <kilobytes> that sets
1726 maximum record size. Similar to -k option for generic frontend
1727 server and yaz-ztest.
1729 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1731 Prefix query parser reports "fail" when bad attribute set is given.
1733 Fix in MARC decoder. Proximity logging. Fix for attribute set
1734 in scan handler for server. Patches by Shigeru Ishida.
1736 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1739 Configure option --with-openssl=<dir> now works when a directory is
1740 specified. Patch provided by Morten Bogeskov.
1742 New option for YAZ client, -u <auth>, that sets authentication.
1744 ZOOM fix: error information was sometimes "missing", since error
1745 was cleared/reset too when it shouldn't.
1747 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1749 --- 1.8.4 2002/01/04
1751 Scan for ZOOM API. New object ZOOM_scanset. New functions
1752 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1753 ZOOM_scanset_destroy.
1755 New ZOOM function, ZOOM_connection_last_event, that returns type
1756 of last event (such as "receive data", "send data", "apdu received",
1759 New ZOOM option, schema, that specifies schema for retrieval.
1761 New CCL feature. Qualifiers can be aliases for one or more
1762 other qualifiers (if more than one is given, OR is used).
1764 ZOOM uses named result sets if target supports it.
1766 Two new YAZ client commands: . (dot, which sources a script of YAZ
1767 client commands), and ! (to execute shell command.). Implemented
1770 Working on Debian packages.
1772 --- 1.8.3 2001/11/19
1774 YAZ client enables named result sets only if target supports it.
1776 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1778 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1779 with key="host" to get same result.
1781 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1782 Function Z3950_resultset_record(s) returns references to records
1783 "owned" by resultset. To become owner use Z3950_record_clone.
1785 Function z_ext_record handles Extended Services. Thanks to
1788 --- 1.8.2 2001/11/12
1790 CCL Parser fix: ignore token comma when dealing with and-lists.
1792 Documentation updates for COMSTACK.
1794 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1795 Changed prototype Z3950_records. For some functions, int parameters
1796 were changed to size_t.
1798 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1801 New MARC decode/display function, marc_display_exl, which properly rejects
1802 non-ISO2709 records. YAZ client uses it.
1804 --- 1.8.1 2001/10/29
1806 Fix bug: local attribute set wasn't set correctly in PQF strings.
1810 * Old Z39.50 codecs no longer supported.
1812 Added ZOOM C binding. See http://zoom.z3950.org/
1814 Renamed states for COMSTACKs to avoid confusion with events.
1816 Implemented cs_look and proper cs_rcvconnect.
1818 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1820 Configure detects POSIX threads on OpenBSD.
1822 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1823 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1825 When error is returned from present handler, non-surrogate diagnostic
1826 is returned in present response (and fetch handler is no longer called).
1828 * Minor adjustments to pquery parser (PQF). Token characters may be
1829 escaped by using backslash (C-style).
1831 PQF parser allows string attribute values to be specified. For @attr,
1832 non-numeric characters after the equal-sign are treated as strings
1833 (e.g. @attr 9=title).
1835 CCL trunction character may be defined (@truncation in file)
1837 * function zget_ExtendedServicesRequest sets waitAction to
1838 waitIfPossible (was wait).
1840 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1843 CCL operator names may be set in field definition files (CCL_bibset).
1844 See ccl/bib1 for an example.
1846 Fixes in ASN.1 compiler for C++ compatibility.
1848 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1849 and "op_or" to avoid conflict with C++.
1851 Fixed problem with GNU readline detection on Redhat 7.0.
1853 Added step-size for Scan backend handler.
1855 Fixed bug that made the frontend server crash when no attribute
1856 set was specified for scan.
1858 Front-end server automatically switches to original working directory
1859 when installed as an NT service. Previously -w had to be specified to
1862 Added extended attributes for retrieval module (data1), so that data1
1863 records carry d1_readXML/SGML attributes. d1_read also supports
1864 null-data rules ( <tag/>)
1866 On UNIX when POSIX threads are available, a separate library libyazthread
1867 is created. Programmers should link with that library and the yaz library
1868 when using threads. The reason for the split was that some applications
1869 on Linux, such as Apache, doesn't work well when using shared objects that
1872 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1873 (or any frontend server) in SSL mode by specifying ssl: followed by
1874 address. Only tested on UNIX.
1876 Added feature for CCL module. Virtual structure s=al or s=ol generates
1877 and-list and or-list respectively instead of phrase search.
1881 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1882 log_mask_str. This was done to avoid name conflicts with other libraries
1883 (such as other PHP extensions).
1885 Added raw OID member for preferred record syntax (request_format_raw)
1886 and returned record syntax (output_format_raw) for backend fetch method.
1888 Config file yaz-config now accepts options so that it returns specific
1889 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1891 Shared library support for UNIX using GNU libtool.
1893 * Modified backend interface. Request/Response struct's replaced by
1894 one read/write C struct. For example bend_fetchrequest and
1895 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1896 Every handler - even search has to be registered in bend_init
1897 handler. This means that the YAZ library no longer refers to
1898 external functions and it makes it possible to make the whole
1899 thing a single DLL/SO.
1901 Added Segment handler for backend server.
1903 Added Zmbol/Zebra administrative functions to YAZ client.
1905 Threaded frontend server on UNIX (when POSIX Threads are available).
1906 Starting the server with option -T enables multi-threading.
1910 Added configure option --enable-comp/disable-comp to control use
1911 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1912 located in sub directory asn.
1914 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1915 in ${exec_prefix}/bin along with the other programs yaz-client and
1918 GNU automake used to maintain makefiles.
1920 Added several OID's.
1922 Changed retrieval module so that we can load records with no abstract
1923 syntax defined. Tagpaths in these records are fully composed of string
1926 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1930 On UNIX, the generated makefile now supports a proper 'make install'.
1931 The prefix can be set via GNU configure to set the install location
1932 (default is /usr/local).
1934 * YAZ programs client and ztest were renamed to yaz-client and
1935 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1936 locations, such as /usr/bin,/usr/local/bin,etc.
1938 * YAZ Header files were moved from include to include/yaz. YAZ Header
1939 files are referred to as include <yaz/log.h> rather than <log.h>.
1940 The YAZ include path (-I ..) is therefore the same as before. Programmers
1941 should update their #include statements or use -Ipath/include/yaz
1942 instead. The main motivation for doing this change is that YAZ header files
1943 can be installed in "standard" locations /usr/include,/usr/local/include
1944 without introducing conflicts, since ALL YAZ header files are stored
1945 in subdirectory yaz (under /usr/include for example).
1947 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1948 rather than project/workspace files. We switched because project files
1949 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1952 Changed name of logging function, logf, to yaz_log, to prevent name
1953 clash with some math-log functions. The YAZ header log.h defines logf
1954 to yaz_log (#define) so there should be no incompatibilities by this
1957 Added bend_start/bend_stop handlers for server. These handler are
1958 called on start/stop of server. For windows they are called whenever
1959 a service is started/stopped.
1961 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1962 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1963 in util/yc.tcl. The auto-generated C code structures are, in a few
1964 cases, incompatible with the old decoders. There are differences in the
1965 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1966 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1967 The preprocessor variable ASN_COMPILED is defined when the compiled
1968 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1969 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1970 wish to use the old encoders/decoders you can specify --disable-yc
1973 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1974 version so that it supports both new - and old version of DB Update
1976 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1977 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1978 change. The name parameter can be set to 0 in which no name is specified
1979 for the construction. The macros odr_implicit and odr_explicit sets name
1980 parameter to zero for the construction involved. New macros
1981 odr_implicit_tag and odr_explicit_tag are similar to the others,
1982 except that a name parameter is added. For programmers' that don't use
1983 ODR they probably only need to change the call to z_APDU and z_External.
1985 Added access control facility by interfacing the TCP wrapper library.
1986 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1987 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1988 name of the daemon and enables the access control as specified in
1989 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1991 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1992 den Dool <H.M.vdnDool@kub.nl>.
1994 Added reference ID parameter to most functions in server API - refer
1995 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1997 Changed name of ccl library to libccl.a (was ccl.a).
1999 Fixed bug in decoder for Explain (Category TargetInfo).
2001 Added support for GNU readline in client. Thanks to Jacob Poulsen
2002 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2004 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2005 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2006 IMPLEMENTATION! This change was made to the development version before
2007 the ZIG decided to retract the amendment. If any users MUST be
2008 compatible with the original Update definition, PLEASE CONTACT US, and
2009 we will include a separate definition corresponding to the old Update
2010 ES. Note that because of the change to the ASN.1 of the
2011 TaskPackageRecordStructure we cannot define a single structure that
2012 will support both versions.
2014 * Added const modifier to buffer parameter for some ODR/BER encoding
2015 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2016 completeWAIS, odr_dumpBER.
2018 Fixed bug in client.c which caused a crash when a scanResponse didn't
2019 contain positionOfTerm.
2021 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2022 * will cause an error in a client if a non-YAZ target sends both a
2023 * list of Scan entries and non-surrogate diagnostics.
2025 Retrieval module enhancements. Tag sets may be typed in the reference
2026 to it. From the .abs-file the "tagset" directive takes a third optional
2027 integer type for the tag set referenced. From a .tag-file the "include"
2028 directive takes a third optional type as well. The old "type" directive
2029 in the tag set itself is still recognized but acts as the default type
2032 Backend interface change. Individual Scan terms returned from bend_scan
2033 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2034 in include/backend.h.
2036 Retrieval module enhancements. Multiple tag sets and attribute sets may
2037 be specified in abstract syntax specs. Revised the error/warning for
2038 logging messages reported by the retrieval module when reading the
2041 Object Identifier system (oid_..) changed. The API is backwards
2042 compatible but the oid-routines now allocates new OID's when needed.
2043 Raw OID's may be specified in oid_getvalbyname.
2045 YAZ now uses GNU configure to generate Makefile(s).
2047 * Minor changes in some of the member names of DeleteResultSetRequest and
2048 DeleteResultSetResponse. See include/proto.h.
2050 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2051 and added member 'languages' in TargetInfo (which was missing).
2053 Changed the way attribute sets are handled in the retrieval
2054 module. These are now cached, just like the abstract syntaxes
2057 Changed YAZ so that it links with compiled ASN.1.
2059 Added Explain-schema definitions and mapping routines. The following
2060 Explain categories have been implemented: AttributeDetails,
2061 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2063 Fixed minor bug in Windows version of Server Library.
2065 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2067 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2069 Added EXTERNAL: UNIverse Resource Report (non-standard).
2071 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2072 ENUMERATED and SET OF.
2074 * Added 'const' to some of the char pointer arguments for the
2075 functions, data1_read_node, data1_getelementbytagname,
2076 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2079 Fixed bug in data1_insert_taggeddata - the last_child member of
2080 parent wasn't initialised.
2082 * Changed data1_read_record and data1_read_node so that the supplied
2083 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2084 doesn't refer to any parts of the "SGML"-buffer.
2086 Fixed bug in server library (Windows version of statserv_remove).
2088 * Changed code so that it compiles as C++. The type definition
2089 of Odr_fun which is a member of Odr_arm was changed. The result is,
2090 that an explicit typecast is needed for the fun pointer when
2091 using Odr_arm - as in:
2092 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2094 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2096 Implemented the new structured date and time definition as approved
2097 by the ZIG. Added schemaId element to the specificTag in Espec-1
2098 (also approved at the last ZIG). Thanks to RVDM.
2100 Added some Object identifiers (RVDM).
2102 Changed the Update Extended Service (RVDM).
2104 Added command "refid" to client which specifies referenceId for
2105 the following requests.
2107 Implemented extended service handling for server. See ztest.c
2108 for an example as well as backend.h. New handlers are registerd
2109 in the Init handler.
2111 * Changed interface for sort in server.
2113 Added new members to statserv_options_block. It allows a server
2114 to read options from another source than just the command line. Thanks
2115 to Charles Woodfield.
2117 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2118 renamed to zboolean. Some C++ compilers complained about the name.
2120 Minor changes to gils.abs. Added index 's' (sort) on title
2121 and date/time-last-modified.
2123 --- 1.4pl2 1998/1/30
2125 Fixed bug in server library regarding inetd mode (-i). This bug
2126 was introduced by release 1.4.
2128 --- 1.4pl1 1998/1/29
2130 Added sort facility in client and backend server interface.
2132 Fixed problem with dependencies in Makefile(s).
2134 Fixed bugs for encoders/decoders of extended services and
2137 Implemented sub-tree feature for schemas. Sub-trees are
2138 referenced in *.abs-files. See explain.abs for an example
2139 of the use of this feature.
2141 Modified bib1.att; local attributes for ANY didn't include
2142 ANY itself (only affects use of the retrieval module).
2144 Fixed bug in plain SGML reader in function data1_read_node:
2145 tags with prefix "var" was incorrectly interpreted as variants.
2147 Added feature "sub-schemas" to enable references to - and definitions
2148 of - group of elements.
2150 * Removed member parent from type data1_element (in data1.h).
2152 Implemented function odr_nullval() that returns the value of
2155 * Removed member num_children from data1_node (in data1.h).
2157 Made NT service interface part of the server library. The
2158 function statserv_main uses the NT service when required and
2159 calls the statserv_start / statserv_close routines.
2161 Routine zget_SearchRequest and zget_PresentRequest fills
2162 resultSetName/Id member with "default" instead of "Default".
2164 Fixed memory leak in server. Request queue member wasn't freed.
2166 Fixed nmem_exit so that memory is freed.
2170 Revised the CCL parser utility to be thread safe.
2172 Added function, oid_ent_to_oid, to replace the function
2173 oid_getoidbyent, which is not thread safe.
2175 * Added nmem_init and nmem_exit to initialize and release
2176 NMEM resources. Function nmem_init should be called once in the
2177 initial thread before NMEM/ODR is used. statserv.c and client.c
2178 have been changed accordingly. The change was necessary to make
2179 NMEM thread safe. The NMEM memory pool is shared amongst threads
2180 in a process. Unix-based applications will still work fine without
2183 Added NT Services interface for the the Z39.50 (statserv) Server.
2184 Refer to the ztest.c source on the usage.
2186 Windows 95/NT port using MSVC5.0. Project files are included in the
2189 * Defined new 'global' handle for the retrieval (data1) system. The
2190 new handled, data1_handle, describes the state of the data1 system.
2191 This handle is passed as first argument to virtually all
2192 data1 related routines. The functions data1_create and data1_destroy
2193 creates and destroys a data1 handle respectively.
2195 Added ODR encode stream member to all backend request structures
2196 init, search, scan etc. This stream should be used to allocate all
2197 memory used for the response when thread safe operation is needed.
2199 Changed the comstack utility, cs_addstr, to be thread safe. The
2200 returned hostname string returned by the function is now part the
2203 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2204 function. The cs_straddr takes a COMSTACK handle as argument, so this
2205 function must be used after cs_create and before bind/connect.
2206 This function is thread safe.
2208 Moved test server to 'ztest' directory - generic server code still
2209 in 'server' directory.
2211 Made prefix query (pquery.c) utility thread safe.
2213 Added new function modifier YAZ_EXPORT to 'export' public DLL
2214 functions when using windows (see include/yconfig.h).
2216 Added definitions to the OID database (util/oid.c) (RVDM).
2218 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2220 Added call to ccl_rpn_delete in client program.
2222 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2223 release of RPN structure.
2225 Added support for C++, headers uses extern "C" for public definitions.
2226 With input from RVDM.
2228 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2229 Thanks to Ronald van der Meer (RVDM).
2231 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2233 Added support for private extensions to the OID database
2234 (oid_setprivateoids()). Thanks to RVDM.
2236 Added optional, physical ANY (key replication)
2238 Fixed null-reference problem in GRS-1 output filter.
2240 Proximity operator added to Prefix Query Format (PQF).
2242 In test client command "base" accepts multiple databases.
2244 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2248 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2250 Smallish bug-fixes in the new encoders/decoders (explain).
2252 Bug fixed in DeleteRequest.
2254 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2256 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2258 Added SOIF syntax (using private OID for now) to retrieval module and client.
2260 Added Update extended service.
2262 Added SearchResult-1 additional info structure.
2264 Added optional CCL (ISO8777) interpreter as separate module. Available
2267 --- 1.2 1996/6/10 (1st anniversary release)
2269 Added Summary record syntax. Lightly tested.
2271 Added OPAC record syntax. Untested.
2273 Added ResourceReport service encoders/decoders. Untested.
2275 Fixed bug in z_Unit - wrong tagging on unitSystem.
2277 Fixed bug in the DiagRecs decoder.
2279 Added options for max PDU size and session timeout to frontend-server.
2281 Added documentation of query-language parsers and other supporting utilities.
2283 [frontend-server] Added Attribute set to the bend_scanrequest API.
2285 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2286 surrogate diagnostics were generated.
2288 [retrieval] Allow multiple local values for attribute.
2290 [retrieval] Allow multiple attributes per element in .abs files. index type.
2292 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2294 --- 1.1pl2 1996/4/10
2296 Minor changes, mostly specific to Zebra's requirements (retrieval)
2300 Repaired bug in frontend server when running multiple listening
2301 endpoints in dynamic mode.
2303 z_External() now won't break if a known, ASN.1 value comes encapsulated
2304 in an octet-string. The value will pass through unmodified in an Odr_oct.
2306 Added a bit of code to the demo client to decode & display
2307 ASN.1-structured records represented in the octet-aligned branch of
2308 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2310 Added z_ext_getentbyref() to the ASN module. Doc updated.
2312 * Completed the SCAN definition in the ASN module. This may break SCAN
2313 code based on older YAZ-versions at compile-time. The fix is easy -
2316 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2317 under the SCAN definition. Remember to initialize this, server-people.
2319 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2320 that this does not extend to ODR and ASN.
2322 Comstack allows insertion of established socket (primarily for
2323 inetd-operation of servers). Doc updated.
2325 Front-end server can now start from the inetd in TCP mode. Doc
2328 --- 1.0pl4 1996/1/24
2332 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2333 the rank and record number.
2335 Adjustments to the frontend server.
2337 Fixed diagnostic BER dumper. It ignored the file argument.
2341 Various changes to retrieval module.
2343 Changed the union discriminators of the protocol files from enums to
2344 ints paired with #defines.
2346 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2349 *Changed operator in the RPN structure to 'roperator', again to avoid a
2352 Fixed problems in Explain decoders/encoders.
2354 --- 1.0pl2 1995/12/6
2356 Memory bug in log module fixed.
2358 --- 1.0pl1 1995/12/5
2360 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2362 Bug in Explain DatabaseInfo module fixed.
2364 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2368 The shift to v1.0 signals that we now consider the *core* functionality
2369 of YAZ reasonably stable (the core being more or less equivalent to
2370 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2371 tested (Explain not at all - though that will happen soonish).
2373 Minor changes to code to support Windows port.
2375 Various minor changes after we're getting to use GRS-1 & co. more.
2377 Added Espec-1 format.
2379 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2380 of the protocol and it cannot be selected when encoding (maps into 'string'
2381 when decoding). Needed to talk to some servers.
2383 Demo client can request simple element set names.
2385 Added Diagnostic Format encoders/decoders.
2387 Added simple Close handling to frontend server (no hooks for resource
2388 reporting yet), and demonstration client.
2390 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2392 --- 1.0b3 1995/08/24
2394 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2395 handled incorrectly when records were requested in the searchResponse. This
2396 will only affect you if you use the frontend-server.
2398 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2399 Test-client will ask for and print GRS1. Ztest will return dummy records
2402 Added Explain encoders/decoders to the service-level API. Untested.
2404 Added Extended Services: Item Order encoders and decoders to the Service-
2405 level API. Untested. We could use a recent copy of the pertinent bits
2406 of the ILL protocol to add those bits.
2408 Added diagnostic format 1 encoders/decoders to the service-level API.
2411 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2412 odr_cons.c, which causes a more correct output.
2414 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2415 was always set to 0 when no records were requested in the searchRequest.
2417 * Added better external-handling. This shouldn't harm old code that
2418 *encodes* externals. It can break code that looks for a
2419 'single-ASN1-type' representation, since those types that are known
2420 are now decoded immediately. Look at the SUTRS sample code in
2421 seshigh.c and client.c. Documentation updated.
2423 Handling of structured records in bend_fetchresponse. Length -1 marks
2424 structured record, type is deduced from format field.
2426 --- 1.0b2 1995/06/27
2427 Fairly quick maintenance release to add SUTRS support.
2429 Fixed handling of SUTRS records in the demonstration client.
2431 * Added format field to the bend_fetchrequest and bend_fetchresponce
2432 structures of the backend API (frontend server). When the record is
2433 returned, the value of the format field is mapped to an OID. The
2434 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2435 of the record. The special value VAL_NONE in the bend_request means
2436 that no specific format was requested by the client. Documentation
2437 updated accordingly. Test server (ztest) will return a fixed dummy
2438 SUTRS record if your client requests SUTRS.
2440 Documentation updated accordingly.
2442 You can now set external libraries and RANLIB support in the top-level
2446 First public release.
