1 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
2 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
4 ZOOM C now interprets databaseName option for ZOOM connection as path
7 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
9 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
11 Dummy Libxml2 types no longer defined in headers of YAZ'.
13 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
18 Various ODR chapter fixes.
20 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
22 Added missing source for Windows compilation, mutex.c.
24 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
26 For SRU connections in ZOOM all records up to "count" are now fetched.
28 Fixed crash in generic frontend server (and yaz-ztest) which occurred
29 in Windows due to bad error handling for Libxml2.
31 Added facility for sending arbitrary records (ASN.1 any) using
32 ZOOM C's Extended service update. Patch by Sam Reynolds.
34 New options for ZOOM C's connection, logapdu which makes ZOOM log
39 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
43 Fixed memory violation that could occur when decoding UTF-8. This bug
44 was only present in 3.0.30 of YAZ.
48 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
49 GNU TLS is used by default (if found).
51 yaz-ztest returns OPAC records if a client asks for OPAC.
53 Improved speed of MARC-8 encoding.
55 Added support for lossy and loss-less MARC-8 encoding.
57 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
59 Added new Windows Service wrapper (sc).
61 yaz-client's itemorder command may now send a file.
63 Fixed yaz-marcdump to allow the use of NS prefix for record element.
65 Added new function yaz_log_xml_errors.
67 Allow (but warn) unknown XML attributes in MARCXML parsing.
69 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
71 The UTF-8 to MARC-8 conversion now uses a different set of characters
72 for Greek symbols. Bug #2120.
76 Added yaz_daemon (daemon.h).
78 Fixed bug #2068: pkg-config trouble
80 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
84 Document --with-xml2 option.
86 Added OPAC XML XSD (etc/opacxml.xsd).
88 Allow glob mask for name attribute in retrieval element for the
89 generic frontend server's retrieval facility.
91 Changed yaz_poll_poll to return yaz_poll_except for all returned events
92 except POLLIN/POLLOUT.
94 Fixed error handling in cs_listen. Bug #2037.
98 Fixed version in yaz/yaz-version.h.
100 Fixed bug #2027: Crash when closing connection.
102 Changed configure so that ICU support is only enabled if only ICU
103 and Libxml2 is available (because the ICU chain is XML based).
105 --- 3.0.20 2008/01/15
107 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
108 is built. Only this DLL depends on the ICU runtime.
110 yaz-ziffy is no longer part of YAZ. It is distributed separately by
111 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
113 Changed license of CCL module to 'Revised BSD'. After consultation with
114 remaining members of the original EUROPAGATE consortium, we are re-issuing
115 the CCL module without a separate license. The software was developed by
116 Index Data as part of a research project. The special license was included
117 to help feed usage information back to the project consortium to support
118 project evaluation. At this time, the project consortium has long-since
119 disbanded, and the majority of the original principals have retired. At the
120 same time, we have significantly modified the software during the following
121 years, to the point where very practically no original code remains. To
122 simplify re-use of the software, we have contacted those members of the
123 consortium who could be reached, and agreed to re-issue the module as a
124 proper part of the YAZ package.
126 Tcl scripts uses /usr/bin/tclsh as preferred shell.
128 CQL closer to being version 1.2 compliant. CQL also allows free-form
129 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
132 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
133 bug could make Extended services handling crash in the ZOOM layer. This
134 bug was only present in YAZ 3.0.18.
136 --- 3.0.18 2007/12/19
138 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
141 yaz-marcdump reads and writes collection wrapped records.
143 Handle OPAC for record conversion module.
145 Fixes for ICU wrapper.
147 Allow ICU libs to be controlled with --with-icu .
149 --- 3.0.16 2007/11/12
151 Added yaz_poll which is a wrapper for select/poll. When poll is available
152 and non-buggy, it is used, by yaz_poll . This allows more than 1024
153 sockets to be in use.
155 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
156 functionality through an XML based configuration (ICU chain). This system
157 is useful for search facilities such as Pazpar2 and Zebra that needs to
158 perform tokenization of indexed material. The ICU code in a separate
159 library libyaz3_icu.a.
161 Added HTTP tunnel facility for COMSTACK, bug #1752.
162 This is a facility that allows a Web proxy, such as squid, to tunnel
163 Z39.50 traffic. This facility is "transparent" to must applications
164 using YAZ. It's enabled by using pseudo transport connect: followed by
165 the proxy address, followed by command, then follwed by he regular
166 "virtual" addresss. For example,
167 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
169 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
171 --- 3.0.14 2007/09/21
173 Fixed bad memory reference in ZOOM_record - cuased by member not being
174 initialized. This was a problem only in YAZ 3.0.12.
176 Fixed bug in conversion from MARC to XML: Non-XML characters in control
177 fields were not removed.
179 Changed the way C code is generated from codetables.xml. Made a MARC-8
180 conversion trie for each characterSet section rather than codeTable.
181 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
182 of codetables.xml from Larry Dixson, LOC. Bug #1464.
184 --- 3.0.12 2007/09/12
186 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
187 from ZOOM_record_error).
189 ZOOM C function ZOOM_record_get returns record schema for type="schema".
191 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
193 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
195 Better SRW-to-Bib-1 diagnostic mapping.
197 ZOOM C and yaz-client announces SRU version 1.2 by default.
199 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
202 Fixed in yaz_sru_decode to allow other version than 1.1.
204 --- 3.0.10 2007/08/22
206 Added support for SRU scan for ZOOM.
208 Added support for the use of the older versions or Extended Service
209 Update in ZOOM. To faciliate this, an option "updateVersion" may be
210 set to the version , 1=first, 2=second, 3=third. The third version is
211 what ZOOM C has used so far. And that, obviously, is the default.
213 Added support for CCL queries in Z39.50 queries sent to the GFS (and
214 therefore in Zebra and in SimpleServer-based applications). The new
215 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
216 qualifier file used to transform incoming CCL queries into Type-1 RPN,
217 which is passed into the back-end search callback function.
219 Added support for HTTP Basic authentication in clients: the SRU/W
220 codec encodes the username/password elements of the PDU structure
221 appropriately, and these may be set using the "user" and "password"
222 options in ZOOM-C applications (the same options that are used for
223 Z39.50 authentication).
227 Fixed bug #1208: SSL appears to be broken in ZOOM.
229 Fixed bug #1206: Libxml2 include path weirdness.
231 Added oid_name_to_dotstring.
233 Allow elementSetName to be specified for ZOOM C record update.
235 Allow waitAction to be specified for ZOOM C based for Extended Services.
237 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
238 syntax OID. Bug introduced in YAZ 3 series.
240 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
244 Fixed bug #1157: yaz-client does not read .yazclientrc from current
245 directory. yaz-client now reads commands from file given by option -f
246 if specified; then tries to read .yazclientrc in current directory.
247 Failing that, it reads .yazclientrc from user's home directory.
249 Added support for correlationInfo Note and ID for Record Update via
252 Added yaz-client command querycharset which specifies character set for
253 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
254 (termListAndStartPoint).
256 Charset ISO5428:1984 is an alias for ISO5428-1984.
258 Implemented a way to perform scan in a result set using Z39.50. This
259 is achieved by attaching the result set name in the characterInfo
260 (type InternationalString) of OtherInformation in the Scan Request PDU.
261 The result set is identified in the otherinformation by the new OID:
262 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
263 This allows for scan in result set and faceted search . Zebra did some
264 of this in the APT term using attribute type 8 and value being result
265 set. Using the OtherInformation approach for this is cleaner and easier
266 to work with in proxies and the like. This facility can be used in
267 yaz-client using new command setscan which takes a result set as first
268 argument, start position (APT) as second.
270 Changed decoding of SRU XML packed records to deal with servers that
271 have recordData with XML data with multiple root nodes. Also make
272 comparison for recordPacking case insensitive. Again, one server
273 returns "XML" where others return "xml".
275 For SRU responses allow Content-Type application/xml as well as text/xml.
279 Fixed bug in character set conversion of BER strings. Bug introduced
284 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
286 For OID class, use oid_class consistently.
288 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
291 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
292 character set for bibliographic information interchange". By Giannis Kosmas.
294 Added documentation on new OID API.
298 Changes to generic frontend server interface: added new member
299 'query_charset' for bend_initrequest structure. A backend init handler
300 should set this member to its native character set for query terms.
301 When defined, the frontend server logic will announce this character set
302 to a client if the negotiationModel bit is set by the client. All server
303 implementors are encouraged to specify this. If a backend server does not
304 specify this a warning is issued using yaz_log(YLOG_WARN,..).
306 Added CCL utility to remove terms (stop words) from resulting RPN
307 tree. This is handled by functions with prefix ccl_stop_words_ .
309 New ZOOM C option, "rpnCharset", which allows client-side conversion of
310 terms in RPN queries.
312 Clean-up the CCL API. Moved some internal structures from ccl.h to
313 private header cclp.h. Changed ccl_parser_create so that a Bibset must
314 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
315 This is replaced by ccl_parser_find_str which takes a string instead.
317 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
318 libyaz.la is the core of YAZ except the generic frontend server and
319 does not depend on POSIX threads anymore. libyaz_server.la is the
320 generic frontend server facilities and uses POSIX thread functionality
321 if available. The libyaz.la no longer depends on POSIX threads because
322 the number of global structures is limited. NMEM no longer re-uses blocks
323 between threads ; it simply free's memory immediately but allocates in
324 "large" chunks as usual. We don't expect any performance penalties
325 because of this. The yaz_log system is still using a global log_level so
326 caution must be taken when modifying it with yaz_log_init_.. +
327 yaz_log_mask_str. This, however, should not cause any trouble because
328 these functions are called during initialization of application code
329 anyway. `yaz-config --libs server` returns libs for server applications;
330 `yaz-config --libs` returns libs for non-server applications.
332 New OID database - with public definitions in oid_db.h. Removed old OID
333 database including the head oid.h and definitions such as enum oid_value
334 and struct oident. The new OID database uses the same string names as
335 before but the 'protocol' is gone. There are now only two representations
336 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
337 converts from string to OID; functions with prefix yaz_oid_to_string
338 converts the other way.
340 Change to emit_term() in CQL-to-PQF query translation: when a term has
341 the /regexp relation modifier, do not process it for leading and
342 trailing "^" and "*", which have quite different meanings in regular
345 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
346 write handlers no longer carries a 'last' parameter. This will make
347 yaz_iconv flush "less" characters. A flush is performed by call to
348 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
350 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
351 removed, because function yaz_query_to_wrbuf does the same.
353 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
354 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
356 Deprecated MARC utility functions removed.
358 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
361 Branch split: YAZ_2_1_55_branch
363 --- 2.1.54 2007/03/16
365 Fix to ZOOM-C so that transparent reconnection is properly handled on
366 connections that are in asynchronous mode.
368 Fixed compilation on OpenBSD 4.0.
370 Large strings in GRS-1 records are now properly displayed in yaz-client.
372 Added character conversion support for "advancegreek"; based on patch from
375 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
376 sequence is met. Before the error was not set so it would be unknown.
378 Adjust yaz-marcdump MARC reader so that it skips until record separator
381 --- 2.1.52 2007/03/07
383 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
384 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
385 fd_set structure used as a bitmask for the FDs to be selected on.
387 Using ACX_PTHREAD macro to check for POSIX threads.
389 Fixed have-vsnprintf check.
391 --- 2.1.50 2007/02/23
393 Fixes for configure on BSD. Bug #900.
395 Added snprintf/vsnprintf wrappers for systems that don't have
396 limits (heavens forbid).
398 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
399 created before all previous tasks were completed and removed from the
400 task queue, the new task could be removed by a mistake.
402 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
404 Implemented pass-through CQL-to-PQF conversions. Bug #861.
406 Fixed bug #832: Problem with MARC/charset in yaz-client.
408 Fixed bug #668: save command line history for yaz-client.
410 Fixed bug #830: pkg-config support.
412 --- 2.1.48 2007/01/23
414 Extended ZOOM result set options with two options that may be read by
415 a client: resultSetStatus and presentStatus with values as specified for
417 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
419 Fixed bug #827: Using SSL fails on Debian etch.
421 Fixed bug #826: Weird looking chars for set of MARC records.
423 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
424 that is treated as an ItemOrder with itemRequest being an XML document
425 external. The value of "doc" is the content.
427 Extended the GFS search facility. New member of bend_search_rr
428 'estimated_hit_count' signals that hits is known to be an estmate
429 (higher or lower than real hit count). New member 'partial_resultset'
430 signals that the search was partial (hit count is lower or equal than
431 real hit count). For Z39.50, the information is stored in resultSetStatus
432 member of SearchResponse APDU. For SRU, the information is signalled
433 via SRU diagnostic 59: "Result set created with valid partial results
436 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
438 --- 2.1.46 2007/01/13
440 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
442 Added ZOOM_connection_peek_event.
444 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
445 the following new functions:
446 ZOOM_event_nonblock, ZOOM_connection_process,
447 ZOOM_connection_get_{socket,mask,timeout},
448 ZOOM_connection_fire_event_{timeout,socket}.
449 The existing blocking event handler, ZOOM_event, is a wrapper for the
450 + blocking ZOOM_event_sys_{poll,select}.
452 Implemented function ccl_xml_config which parses XML version of CCL
453 configuration (bug #798).
455 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
457 Added timings utility (yaz/timing.h)
459 --- 2.1.44 2007/01/03
461 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
464 Fixed bug #779: Rotation of apdu.log fails.
466 Fixed for character set conversions:
467 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
468 Honor G1 set in MARC-8 decoding.
470 --- 2.1.42 2006/12/17
472 Fixed bug #775: char conversion does not handle Alternative UTF-8
475 Implemented function yaz_marc_read_line which parses MARC line format
476 records. There is a wealth of formats out there. So far, this function
477 reads line records produced by yaz_marc_write_line.
479 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
480 more generic and easier to remember(!) options: -i format and -o format
481 which specifies input format and output format respectively - where
482 format is one of "marc", "marcxml", "line", "marcxchange".
484 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
485 does not print anything except warnings for records.
487 For yaz-marcdump, added support for MARC split into files (-s) with a given
490 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
491 spec, at http://www.loc.gov/standards/sru/record-update/
492 This has changed the binary layout of the following structs:
493 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
494 bend_update_rr . Patch by Ko van der Sloot.
496 Added GFS utility function bend_assoc_is_alive which returns 1 if
497 association is still alive (client is connected); 0 otherwise (client
498 closed connection). This allows busy servers to stop working for
501 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
502 been a separate piece of software. This version of ziffy has been modified
503 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
505 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
507 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
508 Client code may now interrogate options such as "init_opt_sort" to
509 find out whether the server claims to support various options.
511 --- 2.1.40 2006/11/27
513 Added utilities yaz_{set,get}_esn to set/get element set name from
516 Removed the build of libyazthread.la. The libyaz.so is the threaded version
517 of YAZ and has been so since YAZ 2.1.10.
519 Implemented ZOOM_record_error which returns error information for
520 record (surrogate diagnostic).
522 --- 2.1.38 2006/10/31
524 Updates for SRU Update by Ko van der Sloot:
525 1. Changed name from "operation" to "action"
526 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
527 versions in the code, marked as 'backward compatible'.
528 3. Added diagnostics for SRU Update.
530 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
532 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
534 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
536 For GFS, fixed problem with SRU diagnostic 'First record position out of
537 range' being issued for 0 hits.
539 zoomtst10 part of Windows Build.
541 --- 2.1.36 2006/10/13
543 Implemented yaz_filepath_comp which splits a path into file path
544 components (required by Zebra 2.0.3+).
546 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
547 BSD inspired license until now so this should not have any real impact on
548 anybody. See http://www.opensource.org/licenses/bsd-license.php
550 Fixed bug #687: Missing log lines.
552 Fixed bug #678: CQL to PQF translation does not preserve double-quote
555 Fixed bug #689: SRU diagnostics to be added.
557 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
558 whether a connection is idle (no more work do do).
560 --- 2.1.34 2006/10/04
562 Change type of optval from long to int for invocation of setsockopt with
563 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
565 Added support for specifying the max log file size for the Generic
566 Frontend Server. The size is given with option -r.
568 --- 2.1.32 2006/09/21
570 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
572 --- 2.1.30 2006/09/17
574 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
577 Fixed bug in Generic Frontend Server that could cause a server to stop
578 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
580 For the generic frontend server, the maximum record size is used as maximum
581 size of incoming packages (SRU + Z39.50). The value until was previously
582 only used in Z39.50 Init negotiation and, later, in a session controlled
583 sizes of records returned. This is controlled using -k option. It can be
584 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
586 --- 2.1.28 2006/09/04
588 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
591 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
593 New option for yaz-marcdump -lpos=value which allows setting a portion
594 of MARC header to a certain value.
596 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
598 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
599 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
601 --- 2.1.26 2006/08/15
603 Fixed problem with SRU mode type (soap, get, post) for yaz-client
606 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
608 --- 2.1.24 2006/08/08
610 Fixed MARC ISO2709 encoding routines to deal with character set
613 Minor changes to GFS logging. Database included in search request log
616 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
617 cached/multiple records.
619 Shared libraries are built by default on Unix+configure.
621 Changed cql2pqf transformation to use a different evaluation order. The
622 new order is: always, relation, structure, position, truncation, index
623 and relationModifier. Old order was: always, relation, relationModifier,
624 structure, index, position, truncation. Note that the the latter ones
625 override former ones for identical attributes.. The new scheme means that
626 it is possible to override any existing attribute with a relationModifier.
627 And also that it is possible to override everything for the index rule
628 (except the ones listed in relationModifier). No order is perfect but this
629 one, we believe, covers more real cases.. The "always" should have been
630 called "default", since the attributes there can be overridden with all
633 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
634 compilation phase, but also for yaz-config --cflags output. This allows
635 us to have public headers with Libxml2 stuff in them . It should also,
636 eventually, make Libxml2 checks redundant in packages using YAZ, such
639 --- 2.1.22 2006/06/15
641 Changed SRU update structure bend_update_rr so that SRU diagnostics are
642 stored in uri, message and details.. Previously diagnostics were stored
643 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
644 compatibility.. but he's probably the only one affected, so.
646 Added support for CCL, compiled on the client side, in ZOOM-C. This
647 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
648 input; the resulting query objects can be used for for searching with
649 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
651 YAZ' configure searches for OpenSSL by default.
653 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
654 SL_CTX_use_certificate_file. See
655 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
656 for more info. Thanks to Ko van der Sloot.
658 --- 2.1.20 2006/06/02
660 Bug #600: SRU GET, POST support for yaz-client. Introduced
661 command 'sru' which selects method SOAP/GET/POST.
663 Allow missingValueAction to be specified for the sortspec string -
664 function yaz_sort_spec. By default, the missing value action is null.
665 Use ! to specify "abort". Use = followed by stringvalue to specify default
668 Ensured that Present-handler (if defined) is called in GFS before any call to
669 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
670 searchRetrieve requests.
672 Documentation for YAZ is now based on the Docbook XML/XSLT using
673 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
674 is no longer depending on jade/openjade or docbook-to-man scripts.
675 PDF is no longer part of the distribution - but can optionally be
676 made using DSSSL/jadetex or FOP.
678 Added retrieval handling support in Generic Frontend Server to support
679 conversion between MARC/XML as well as XSLTtransforms. See
680 etc/yazgfs.xml for an example.
682 Added Authentication support to Generic Frontend Server in SRU
683 mode. Authentication using HTTP Basic is supported, as is the use
684 of 'x-username' and 'x-password' parameters in the request itself.
686 Added support for a new character set MARC8s identical to MARC8 except
687 that it converts combined characters to single Unicode characters in the
688 Latin-1 range (when possible).
690 --- 2.1.18 2006/04/24
692 ASN.1 compiler 0.4: generates brief Doxygen file header for
693 generated .h/.c files.
695 Utility yaz_iconv now supports conversion to MARC-8.
697 New facilities for the MARC module. The reading - and writing of
698 content are separate methods for the yaz_marc_t handle. The following
699 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
700 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
701 format). Write functions have prefix yaz_marc_write_.. The existing
702 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
703 available. Removed support for OAI-MARC and simplexml (not the
704 simplexml from PHP5).
706 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
707 to be returned for this connection.
709 --- 2.1.16 2006/03/31
711 Allow multiple languages and charsets to be specified with
712 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
713 negcharset iso-8859-1,utf-8
715 Translation of proximity nodes from CQL into PQF now works.
717 Moved to automake 1.8, 1.9.
719 Added function yaz_log_set_handler which allows a log handler to be
720 installed. This handler will be called for all log messages. Output
721 to file is also produced; but that can be disabled by passing NULL
722 fname to yaz_log_init_file.
724 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
726 For SRW (including GFS), accept application/soap+xml as content-type
729 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
730 produces NO stylesheet reference even if a default stylesheet is specified
733 --- 2.1.14 2006/03/14
735 Updated Windows package to include yazd.dll + yazd.lib for the
736 Development component.
738 If the environment variable YAZ_LOG is set, then it is used as a
739 string indicating the default level of logging to use if not
740 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
741 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
742 used as before. So, for example, to omit warnings from YAZ logging,
745 cql_transform() now map structure and other attributes before indexes,
746 so that index-specific structures and other attributes can override
747 defaults. So now a combination of mapping specifications such as:
749 index.dc.date = 1=date-modified 4=5
750 does the right thing.
752 cql_transform() now also respects the "always" mapping specification,
753 which establishes an initial set of attributes to be used for all
754 terms except where overridden by more specific attributes associated
755 with the index, relation or modifier.
757 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
758 which mode to use; one of "post", "get" or "soap" (SRW, default).
760 Fixes for yaz_iconv routines: changed trie-based character set conversions
761 to use only non-negative values for bit fields due to Sun's C compiler not
762 supporting negative values.
764 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
765 sequences where not read correctly. Fix by Rustam Usmanov.
767 Updated win/makefile to use options, settings which makes things
768 compile with VS C 2005.
770 --- 2.1.12 2006/02/01
772 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
774 In ZOOM socket code, use select instead of poll on MacOSX.
776 ZOOM-C now support client-side compilation of CQL into RPN that is
777 sent to the server, enabling CQL to be used against all Z39.50
778 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
779 ZOOM_query object, and submit it using ZOOM_connection_search().
780 The CQL-to-RPN translation uses a configuration file, the name of
781 which must be specified in the Connection's "cqlfile" option.
783 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
784 function, which takes as its start-term parameter a ZOOM_query object
785 (which may have had either CQL or RPN set into it).
788 --- 2.1.10 2005/11/29
790 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
791 GFS to support this as well. Backend handler, bend_srw_update, does the
792 update work. Code contributed by Ko van der Sloot.
794 Allow retrieval of Search Result-1 information in ZOOM by the use of
795 options that are attached to a result set. ZOOM documentation updated
798 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
799 UTF-8 conversion. Patch by Raj Patel.
801 Added option -m to GFS to control formatting of timestamps in log file.
803 Added 'exit' as synonym for 'quit' in yaz-client
805 Added support for specifying SRW resultSetId + resultSetIdleTime in a
806 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
807 for the new members. Patch by Ko van der Sloot.
809 Added support for SRU POST. It is supported for content-type
810 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
812 Do not build the separate Multi-threaded (MT) library libyazthread.la.
813 Instead make the library libyaz.la multi-threaded. Threading as a whole
814 can still be disabled by configure option --disable-threads. Previosly,
815 with older GLIBCs there were problems with MT libs under Apache. This
816 has now been fixed a long time ago.
818 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
821 CQL module modified to be case insensitive for relations/indexes/operations.
823 Fixed bug in CQL transform code: incorrect value relationModifieder
826 Added 'show all' command for yaz-client which retrieves all results
829 Added new yaz-client, xmles, which takes a (private) OID and
830 a document to be sent as an extended service request.
832 Describe new yaz-client commands wait_response and set_auto_wait.
834 Increase TCP/IP listener backlog from 3 (which I am guessing was
835 copied from the SunOS manual entry way back when) so SOMAXCONN, so
836 that the socket will queue as many incoming connections as it's able
837 to handle ongoing connections. In other words, it will never now
838 refuse a connection that it would be able to handle merely because
839 it's not got around to accepting() enough of the pending connections
840 yet. This is the behaviour anyway under Linux, where the listen()
841 argument is ignored; but not under BSD and on systems such as
842 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
843 YAZ-based servers should now be uniform across operating systems in
846 yaz-marcdump uses 64-bit file access on some systems. This is enabled
847 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
848 This allows yaz-marcdump to read large MARC batches (>2 GB).
850 Modified all YAZ source files - except the source which is auto-generated
851 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
854 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
855 corresponding to the existing *_setl() function. These allow option
856 values containing arbitrary valuues.
858 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
859 ZOOM_resultset_sort() in new applications. Its behaviour is identical
860 except that it returns an indicator of whether or not the sort
861 criterion was accepted (0 for OK, -1 for invalid).
865 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
866 MARC output rather than returning "new" buffer.
868 yaz-client warns about unknown init options.
870 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
874 Added support for SRW sort in Generic Frontend Server. Patch
875 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
876 sortKeys - or NULL if none is provided.
878 Fixed bug #307: It was impossible to specify indefinite/no timeout
879 for ZOOM_event. Special timeout value -1 now means indefinite timeout
882 Added support for multiple languages and charsets to be specified in
883 ZOOM. Each charset/language is separated by a blank. If negotiation is
884 in effect in init-response, Option
885 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
886 Code based on patch by Vasiliy Osadchuk.
888 Fixed bug #306: infinite recursion that occurred when calling
889 yaz_log_level_init as the first call (before other log level or
892 Fixed bug in scan handling in front end server: if preferred-Position-In-
893 Response was non-present, a NULL pointer referece was performed.
897 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
898 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
899 now defined for all those error codes. So instead of putting 109 in
900 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
901 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
903 Modified the yaz-marcdump utility to skip garbage bytes between MARC
906 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
908 Program yaz-client now exits and produces an error message if multiple
909 Z39.50 servers are specified on the command line (none or one allowed
912 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
917 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
919 Fixed bug #272: Preserve spacing for CCL terms.
923 Added support for virtual hosts and multiple backend servers for
924 the YAZ frontend server. The configution is XML based and
925 support specificition of CQL to RPN mappings and explain information.
926 See section "Virtual Hosts" in the YAZ manual.
928 Extended OPAC display utility. OPAC display utility renders
929 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
930 to supplement yaz_marc_decode_wrbuf.
932 Fixed a bug in MARC decoder that could caused it to crash for some
933 invalid MARC records. More diagnostics and warnings where added in
934 XML output (warnings, etc are stored in comments).
936 --- 2.0.34 2005/02/08
938 Fixes for UNIX domain sockets. Bug #261.
940 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
942 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
943 Added yaz_marc_subfield_str which defines subfield lead string which is
944 used in YAZ_MARC_LINE format. Default string is blank+$. Added
945 yaz_marc_endline_str which defines end of fields string used in
946 YAZ_MARC_LINE format. Default string is newline.
948 Experimental support for MarcXChange. This format can be produced
949 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
950 http://www.bs.dk/standards/MarcXchange.xsd
952 Added yaz-client commands scansize that sets maximum number of
953 entries to be returned by scan.
955 --- 2.0.32 2005/01/11
957 Added support for SRW scan in yaz-client and Generic Frontend Server.
959 * Added whereInList member to SRW Scan Term.
961 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
963 Fixed NMEM system to return aligned blocks on the smallest boundaries
964 that are suitably aligned for all possible types on the particular
965 architecture YAZ is being built for.
967 --- 2.0.30 2005/01/04
969 Fixed numerious warnings that was issued with newer versions of GCC.
971 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
972 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
975 Make YAZ Generic Frontend Server slightly faster.
977 Enhance (and reduce) logging for Generic Frontend Server.
979 Revert YAZ log system so that it flushes every write operation
980 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
982 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
983 instead of LOG_, due to name clash with syslog(3). LOG_ are still
984 present. New applications should define YAZ_USE_NEW_LOG=1 - this
985 will effectively disable old definitions.
987 --- 2.0.28 2004/11/09
989 Added yaz_log_time_format which specifies log format using
992 Added yaz_log_module_level which returns mask for a module. Value
993 is non-zero mask a if module is enabled; zero if disabled.
995 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
996 in include/yaz/cql.h.
998 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1000 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1002 Fixed bug #172: RPM builds does not enable SSL.
1004 Doxyfile.in part of dist. Doxyfile generated by configure.
1006 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1007 are given and the corresponding component does not exist.
1009 Extend CCL documentation in YAZ reference. Describe r=r.
1011 --- 2.0.26 2004/10/01
1013 Fixed MARC->MARCXML conversion to properly deal with
1014 fields, subfields, indicators having non-ASCII characters.
1016 Fixed MARC->MARCXML conversion so that ASCII control characters
1017 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1020 Added YAZ GFS support for conversion from Z39.50 surrogate
1021 diagnostics to SRW surrogate diagnostics.
1023 Bug fix: YAZ GFS did not return schema in explainResponse.
1025 --- 2.0.25 2004/09/30
1027 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1028 now converts recordSchema to elementSetName as well as schema URI.
1030 Fixed bug in COMSTACK that prevented HTTP request packages from being
1033 --- 2.0.24 2004/09/29
1035 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1036 does not require white-space before and after the dash in a range, e.g.
1037 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1040 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1041 due to new GCC removing "redundant" code.
1043 Added yaz-client commands scanpos and scanstep that sets preferred
1044 position and step-size for scan.
1046 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1048 Added CCL utility ccl_qual_buf which parses one or more CCL
1049 spec lines in a buffer.
1051 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1052 of name and value - ignoring empty lines and comments.
1054 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1056 Added odr_get_element_path which returns current element path for an
1057 ODR handle. This utility is useful in error handling or user-defined
1060 Added ODR_PRINT utility odr_set_stream which is is a more generic
1061 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1062 to a write function and pointer to close function. The close function - if
1063 non-NULL - will be called during odr_destroy.
1065 Fixed bug in CCL parser where truncation char was not removed from
1066 right side when truncation=both was in effect.
1068 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1071 --- 2.0.23 2004/08/11
1073 Fix buffer overrun in CQL parser when dealing with proximity (%).
1075 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1076 to UTF-8/UCS conversion is now only based on codetables.xml.
1078 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1080 --- 2.0.22 2004/08/06
1082 Add support for more "commit changes" in ZOOM (uses Extended Services).
1084 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1087 Yet another small fix for configure of SSL.
1089 --- 2.0.21 2004/05/14
1091 Fix SSL libs for configure when --with-openssl=DIR is given.
1093 --- 2.0.20 2004/05/10
1095 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1097 SSL comstack now uses yaz.pem certificate file on server side
1098 by default. Certificate filename can be configured by calling
1099 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1101 Fix bug regarding multiple calls to ZOOM_connection_connect.
1103 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1105 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1106 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1108 ZOOM now allows inspection of X509 peer certificate for verification.
1109 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1111 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1112 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1113 as "modular" but it simplifies things.
1115 Added cs_get_peer_certificate to that returns peer X509 PEM.
1117 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1118 NULL if SSL is unavailable.
1120 Documentation about MARC decoding tools.
1122 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1124 --- 2.0.19 2004/03/30
1126 Rename CHANGELOG to NEWS to follow GNU style packing.
1128 Fix bug with missing initialization of member in init_diagnostics.
1129 This bug affects threaded version of GFS server.
1131 --- 2.0.18 2004/03/20
1133 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1136 Ensure zlib.dll is packed with Windows install.
1138 --- 2.0.17 2004/03/17
1140 Fix encoding of xsd:string to use text instead of CDATA.
1142 Fix endless loop in CQL parser with unbalanced ".
1144 Use a more compact way to store MARC-8 conversion tables.
1146 --- 2.0.16 2004/03/16 Debian only
1148 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1151 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1156 --- 2.0.15 2004/03/01
1158 Another fix for decoding of XML packed records.
1160 --- 2.0.14 2004/02/25
1162 Fixes for Chunked encoding. White space not ignored after length spec.
1164 Update NS and use default NS for SRW diagnostic elements.
1166 --- 2.0.13 2004/02/23
1168 Implement ZOOM_resultset_cache_reset which resets record cache.
1170 Implement ZOOM_resultset_sort which sorts a result set.
1172 Implement chunked HTTP transfer.
1174 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1176 --- 2.0.12 2004/02/16
1178 Added member 'schema' to bend_explain_rr structure so that backend
1179 can specify explain record identifier. Defaults to Zeerex 2.0.
1181 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1183 --- 2.0.11 2004/02/16
1185 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1188 Added init command for yaz-client which sends "extra" init request.
1190 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1191 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1193 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1195 Make ZOOM error code for "invalid query".
1197 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1199 --- 2.0.10 2004/02/05
1201 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1204 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1206 Added option -p <file> to make Generic Frontend Server to write PID file.
1208 Added option -D to put Generic Frontend Server in background on its own.
1210 Make ZOOM C recognize option "password". If unset, "pass" is used
1211 (for backwards compatibility).
1213 Fixed a bug in Generic Frontend Server that could make it crash if a
1214 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1217 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1218 Must be issued before open, in order to be in effect.
1220 --- 2.0.9-6 2004/01/12 Debian/Windows
1222 Make the SRU server more picky WRT unknown params, etc.
1224 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1226 New YAZ client command, options, that sets Z39.50 options.
1228 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1229 options from a string of tokens (one token for each option bit).
1231 Update SRW diagnostic code messages.
1233 --- 2.0.9-5 2004/01/07 Debian/Windows
1235 Handle user defined stylesheet for SRW/SRU.
1237 --- 2.0.9-4 2004/01/06 Debian/Windows
1239 Fix bug in decoding of Content-Length.
1241 --- 2.0.9-3 2004/01/06 Debian/Windows
1243 Fix a bug with decoding of XML packed records.
1245 --- 2.0.9-2 2004/01/05 Debian only
1247 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1249 Fix bug in SRW/SRU diagnostics decoding.
1251 --- 2.0.9 2004/01/05
1253 Fixed bug in Generic Frontend Server which could drop records exceeding
1254 preferred message size. Reported and fixed by Irina Dijour.
1256 Fixed calculation of package size for structured records in Generic
1257 Frontend Server. Reported and fixed by Irina Dijour.
1259 Fixed namespace for SRW/SRU diagnostics.
1261 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1263 --- 2.0.8 2003/12/22
1265 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1266 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1269 CQL changes to reflect recent changes to the specification:
1270 * Documentation talks about context sets instead of index sets.
1271 * Documentation talks about indexes instead of qualifiers.
1272 * The CQL-to-PQF transformer's configuration file now uses
1273 "index.set.name = <attributes>" instead of the old form
1274 "qualifier.set.name = <attributes>". (Both forms are still
1275 understood but the latter is deprecated.)
1276 * CQL terms with no explicit index specified are now interpreted as
1277 cql.serverChoice instead of srw.serverChoice (which of course
1278 behaves exactly the same.)
1280 --- 2.0.7 2003/12/16
1282 MARC conversion can now generate ISO2709 output in another
1283 character set. yaz-marcdump uses this facility if you invoke it
1286 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1287 functions from there can be used from C++.
1289 --- 2.0.6 2003/12/04
1291 Frontend server now transfers memory from decoded packages to stream
1294 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1295 references to show up.
1297 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1298 the ZOOM Abstract API. The older names for the same options are still
1299 also supported for the benefit of old applications.
1301 ZOOM-C supports "implementationId" and "implementationVersion" options
1302 to go along with "implementationName". These allow the user code to
1303 specify identification strings to be sent to servers.
1304 Add OID for the new ExtLite attribute set.
1306 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1307 as requested/supplid by Ere Maijala <ere@atp.fi>
1309 For generic frontend server, reverse the order of
1310 "toolkit-supplied / application-supplied" strings sent as implementationId,
1311 Name and Version. Also, remove the spaces around the slash. This brings
1312 the GFS in line with the behaviour of ZOOM-C on the client side.
1314 Add function ZOOM_scanset_display_term.
1316 yaz-client shows scan displayTerm if present.
1318 Utility yaz-iconv is now installed by default along with the man page
1321 Extend configure check for OpenSSL to use pkg-config where available (such
1324 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1325 server to specify uid/gid/mask for socket using the format
1326 unix:[user=uid,][group=gid,][umask=mask,]file=path
1327 If file= is omitted the existing format is assumed, e.g.
1329 in which case the mask is 0666 (rw for everybody).
1331 Major restructure of YAZ source. All source in libyaz is in src directory.
1332 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1333 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1335 Added man page for utility yaz-marcdump (used to be called marcdump).
1336 yaz-marcdump is installed by 'make install'.
1338 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1339 of incoming package failed.
1341 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1343 Change prototype of odr_perror: add const to message string.
1345 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1347 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1348 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1349 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1350 DNS lookup. There should not be any compatibility problems with this
1351 assuming that blocking=1 or 0 is used.
1353 Fix bad reference in UNIX comstack in function cs_addrstr.
1355 Fix for compilation on AIX.
1357 The generic front-end server (server/seshigh.c) now supports returning
1358 Init diagnostics to the client in User-information-field, in
1359 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1362 --- 2.0.4 2003/09/04
1364 Allow any CQL relation (not just all,any,exact,scr).
1366 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1367 that features the same UI.
1369 Implemented command update0 in YAZ client which is equivalent to
1370 update but uses old of Ext Update ASN.1.
1372 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1373 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1374 Previously no OID was used for this info.
1376 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1377 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1378 returns 'malformed search term' otherwise.
1380 SortResponse member resultCount now set to NULL in sort handler of
1383 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1386 Add three new utility functions for translating OIDs between various
1387 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1388 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1389 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1390 char *oid_to_dotstring(const int *oid, char *oidbuf);
1391 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1393 Reverted modifications for ES Update definition for z_IU0Update
1394 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1395 is back to YAZ 2.0.2.
1397 String value attributes for CCL parser.
1399 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1400 which their FirstSearch server returns in Init responses, sometimes
1401 carrying useful diagnostic information when Init fails. This has the
1402 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1403 "z39.50/oclcui.asn", where its definition is somewhat different from
1404 what OCLC document on their web-site, as required to interoperate with
1407 Support for anonymous authentication in yaz-client. Use the command
1410 * Fix the OID of the Index Data-local "admin" Extended Service from
1411 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1412 the 1000, which indicates a locally-defined OID, was a mistake.
1414 --- 2.0.3 2003/06/20
1416 Fix CCL directive @case handling so that it affects string match for
1417 both CCL keywords and qualifiers.
1419 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1420 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1421 Decoder has been updated with ASN.1 changes as listed in
1422 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1423 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1424 z_IUUpdate, remains unchanged.
1426 ZOOM_record_get may now return a record in a specific character set.
1427 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1428 "from" is the character set of record as returned by target. "to" is
1429 the character set to be returned. If omitted, "to" is UTF-8.
1431 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1433 New ODR utility, odr_getelement, which returns name of element for
1434 which encoding/decoding failed.
1436 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1437 in cases where a required element was omitted.
1439 Bug fix: some MARC8 sequences were not converted.
1441 New ZOOM option "step" which specifies number of records to be
1442 retrieved in one chunk. Used in conjunction with "start" and "count".
1444 SRW support for yaz-client. Use scheme http: to use it, e.g.
1447 yaz-client no longer does (un)intelligent character set conversions
1448 by default. Can be enabled with charset and marc_charset commands.
1450 xmalloc trace fix for 64-bit systems such as DEC alpha.
1452 Solaris 2.6 compile fix.
1454 New function, cql_strerror() translates SRW error codes, as returned
1455 by cql_transform_error(), into human-readable English strings. Used
1456 in yaz-client diagnostics when appropriate.
1458 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1459 converts it into a type-1 query which is sent to the server. This
1460 makes CQL available for use with all Z-servers, as opposed to the tiny
1461 minority that can handle CQL queries themselves.
1463 --- 2.0.2 2003/04/28
1465 New Debian package layout similar to the Redhat Package layout.
1467 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1468 and search result respectively.
1470 --- 2.0.1 2003/04/25
1472 Redhat package is now several packages: libyaz (runtime libraries),
1473 libyaz-devel (development and documentation, and yaz (utility programs).
1474 Package spec file by Morten Bogeskov.
1476 New member 'schema' in struct bend_fetch_rr which the name of requested
1477 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1478 handler MAY set this to reflect the schema of the returned record.
1480 New member 'display_term' in struct scan_entry. GFS now sets member entries
1481 and allocates scan entries to be filled by user scan handler. In previous
1482 version, entries member was allocated by the scan handler. That still works,
1483 but the GFS will ignore member display_term - assuming it was NOT set by
1484 the handler. The fact that the GFS now allocates the entries both allows
1485 for new members and makes a scan handler easier to write.
1487 Fix CQL lex buffer overflow.
1489 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1490 SRU default recordPacking is string.
1492 SRU protocol support for frontend server.
1494 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1496 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1498 Added scan for the ZOOM shell (zoomsh).
1502 * String Identifers for Schemas (Amendment 5).
1503 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1504 Old definition for schema
1505 Odr_oid *schema; /* OPT */
1510 Z_InternationalString *uri;
1511 #define Z_Schema_oid 1
1512 #define Z_Schema_uri 2
1515 * resultCount parameter to Sort Response (Amendment 1).
1516 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1518 Support for SRW 1.0 over HTTP. This is an optional feature and
1519 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1522 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1523 on the same port. SRW SearchRetrieveRequests are mapped
1524 to bend_init,bend_search,bend_fetch,bend_close.
1526 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1528 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1529 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1531 ZOOM connections are SRW based if schem http is used for hostname
1532 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1533 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1535 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1536 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1537 distance=n, order=true/false, relation=le, prox unit=word. If
1538 n is omitted, distance 1 is used.
1540 Fixed problem with C compiler include path in wrong order.
1542 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1543 on Solaris. Patch from Ko van der Sloot.
1545 New MARC decode API. All new functions operate on a yaz_marc_t
1546 handle. The most important new functions are: yaz_marc_create,
1547 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1548 decode and destroy respectively. Decoder can produce formats
1549 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1550 include/yaz/marcdisp.h.
1552 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1553 to UTF-8, UCS-32, wchar_t or Latin-1.
1555 * Prototypes for yaz_iconv_-functions moved to separate header
1556 include/yaz/yaz-iconv.h.
1558 Make a few private functions 'static' in unix.c. This prevents
1559 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1561 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1562 are set when Init Response is received.
1564 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1565 but returns diagnostic set as well.
1567 New function yaz_strerror which is a portable wrapper for
1568 strerror/strerror_r/GetLastMessage.
1570 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1571 is returned for MARC. If type is "oai", then OAI MARC is returned.
1573 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1576 --- 1.9.2 2002/11/26
1578 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1580 Fix bad race conditions on SIGTERM and terminate gracefully in
1583 Move retrieval (data1) module to Zebra since nobody seems to be
1586 Add GRS-1 render for ZOOM using same format as yaz-client.
1588 --- 1.9.1 2002/10/05
1590 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1592 Fix broken ESpec handling in data1 module.
1594 SGML reader parses comments and makes them part of the data1 tree.
1596 Added several type casts so that YAZ compiles as C++ code.
1598 ZOOM didn't handle PDU encoding failures properly.
1600 Added more Bib-1 diagnostics (approved extensions).
1602 GNU configure: better check for iconv.
1604 More portable use of accept, getpeername. Check for socklen_t. Use
1605 int/size_t if socklen_t is not defined.
1609 PQF parser rejects bad queries - including those with extra
1610 characters in them. PQF parser used to silently ignore that.
1611 Cleaner API for PQF added, which allows you to get detailed
1612 error information for bad queries (see yaz/pquery.h).
1614 Fixed bug in ZOOM_record_get for type "database".
1616 Implemented mini iconv library supporting conversions between
1617 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1619 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1621 --- 1.8.9 2002/08/20
1623 Fixed ZOOM C record cache so that preferredRecordSyntax and
1624 elementSetName is used to check for already fetched records.
1626 --- 1.8.8 2002/08/02
1628 Added three members in bend_initrequest structure to facilitate
1629 character set negotiation.
1631 Fixed a bug in frontend server that could cause indefinite
1632 loops under rare conditions.
1634 Revised character set utilities (charneg.h) so that encoding
1635 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1637 For PQF, directive @term <type> sets term type for Scan/Search.
1638 Here <type> is general, string, numeric, null. The term type
1639 is inherited - just like @attr.
1641 New call odr_set_charset that sets character set conversion for
1642 international-strings on a ODR stream. Prototype is:
1643 int odr_set_charset(ODR o, const char *to, const char *from);
1644 The InternationalString is still represented as C string in YAZ
1645 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1646 won't). On the protocol level, you can use any encoding.
1648 Support for UNIX sockets in ZOOM.
1650 Solaris recv sometimes returns errno == ENOENT. It is treated as
1651 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1653 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1654 both client and server. Code by Morten Bogeskov.
1656 --- 1.8.7 2002/05/22
1658 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1659 that they can be used directly from Visual Basic. You must recompile
1660 your windows APP if you're using ZOOM.
1662 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1663 Commands "lang" and "charset" sets language and character set respectively.
1664 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1665 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1667 Attributes from multiple CCL fields may be OR'ed rather than merged
1668 using directive "@field or". Fields are still merged by default -
1669 equivalent to "@field merge".
1671 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1674 Fixed bug in zget for parameter ExtendedServicesResponse.
1678 --- 1.8.6 2002/03/25
1680 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1682 Client displays USR.1:SearchResult-1 (hits per term).
1684 Additional Search Info for search in Generic Frontend Server.
1686 Fixed CCL parsing of "field=s".
1688 WIN32 installer - using the excellent NSIS software from nullsoft.
1690 Fixed CCL parsing of "field = - <number>".
1692 Added function yaz_marc_decode that decodes MARC for line mode
1693 display or XML (similar to that used by JZKit).
1695 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1696 Z39.50. But ISO/ILL was, however.
1698 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1699 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1701 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1702 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1704 --- 1.8.5 2002/02/03
1706 New YAZ client features: Command completion and new commands:
1707 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1708 Code provided by Jacob Poulsen.
1710 New call oid_trav, that visits all registered OIDs via callback.
1712 Function ZOOM_record_get now returns const char pointer rather than
1713 void pointer. It saves a lot of type casts.
1715 For YAZ client, command "auth" now allows you to set authentication
1716 in IdPass style. It is enabled when three tokens are given - order
1717 is user, group and password.
1719 Fix memory leaks in MARC record handling for ZOOM.
1721 New option for YAZ client, -k <kilobytes> that sets
1722 maximum record size. Similar to -k option for generic frontend
1723 server and yaz-ztest.
1725 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1727 Prefix query parser reports "fail" when bad attribute set is given.
1729 Fix in MARC decoder. Proximity logging. Fix for attribute set
1730 in scan handler for server. Patches by Shigeru Ishida.
1732 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1735 Configure option --with-openssl=<dir> now works when a directory is
1736 specified. Patch provided by Morten Bogeskov.
1738 New option for YAZ client, -u <auth>, that sets authentication.
1740 ZOOM fix: error information was sometimes "missing", since error
1741 was cleared/reset too when it shouldn't.
1743 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1745 --- 1.8.4 2002/01/04
1747 Scan for ZOOM API. New object ZOOM_scanset. New functions
1748 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1749 ZOOM_scanset_destroy.
1751 New ZOOM function, ZOOM_connection_last_event, that returns type
1752 of last event (such as "receive data", "send data", "apdu received",
1755 New ZOOM option, schema, that specifies schema for retrieval.
1757 New CCL feature. Qualifiers can be aliases for one or more
1758 other qualifiers (if more than one is given, OR is used).
1760 ZOOM uses named result sets if target supports it.
1762 Two new YAZ client commands: . (dot, which sources a script of YAZ
1763 client commands), and ! (to execute shell command.). Implemented
1766 Working on Debian packages.
1768 --- 1.8.3 2001/11/19
1770 YAZ client enables named result sets only if target supports it.
1772 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1774 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1775 with key="host" to get same result.
1777 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1778 Function Z3950_resultset_record(s) returns references to records
1779 "owned" by resultset. To become owner use Z3950_record_clone.
1781 Function z_ext_record handles Extended Services. Thanks to
1784 --- 1.8.2 2001/11/12
1786 CCL Parser fix: ignore token comma when dealing with and-lists.
1788 Documentation updates for COMSTACK.
1790 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1791 Changed prototype Z3950_records. For some functions, int parameters
1792 were changed to size_t.
1794 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1797 New MARC decode/display function, marc_display_exl, which properly rejects
1798 non-ISO2709 records. YAZ client uses it.
1800 --- 1.8.1 2001/10/29
1802 Fix bug: local attribute set wasn't set correctly in PQF strings.
1806 * Old Z39.50 codecs no longer supported.
1808 Added ZOOM C binding. See http://zoom.z3950.org/
1810 Renamed states for COMSTACKs to avoid confusion with events.
1812 Implemented cs_look and proper cs_rcvconnect.
1814 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1816 Configure detects POSIX threads on OpenBSD.
1818 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1819 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1821 When error is returned from present handler, non-surrogate diagnostic
1822 is returned in present response (and fetch handler is no longer called).
1824 * Minor adjustments to pquery parser (PQF). Token characters may be
1825 escaped by using backslash (C-style).
1827 PQF parser allows string attribute values to be specified. For @attr,
1828 non-numeric characters after the equal-sign are treated as strings
1829 (e.g. @attr 9=title).
1831 CCL trunction character may be defined (@truncation in file)
1833 * function zget_ExtendedServicesRequest sets waitAction to
1834 waitIfPossible (was wait).
1836 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1839 CCL operator names may be set in field definition files (CCL_bibset).
1840 See ccl/bib1 for an example.
1842 Fixes in ASN.1 compiler for C++ compatibility.
1844 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1845 and "op_or" to avoid conflict with C++.
1847 Fixed problem with GNU readline detection on Redhat 7.0.
1849 Added step-size for Scan backend handler.
1851 Fixed bug that made the frontend server crash when no attribute
1852 set was specified for scan.
1854 Front-end server automatically switches to original working directory
1855 when installed as an NT service. Previously -w had to be specified to
1858 Added extended attributes for retrieval module (data1), so that data1
1859 records carry d1_readXML/SGML attributes. d1_read also supports
1860 null-data rules ( <tag/>)
1862 On UNIX when POSIX threads are available, a separate library libyazthread
1863 is created. Programmers should link with that library and the yaz library
1864 when using threads. The reason for the split was that some applications
1865 on Linux, such as Apache, doesn't work well when using shared objects that
1868 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1869 (or any frontend server) in SSL mode by specifying ssl: followed by
1870 address. Only tested on UNIX.
1872 Added feature for CCL module. Virtual structure s=al or s=ol generates
1873 and-list and or-list respectively instead of phrase search.
1877 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1878 log_mask_str. This was done to avoid name conflicts with other libraries
1879 (such as other PHP extensions).
1881 Added raw OID member for preferred record syntax (request_format_raw)
1882 and returned record syntax (output_format_raw) for backend fetch method.
1884 Config file yaz-config now accepts options so that it returns specific
1885 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1887 Shared library support for UNIX using GNU libtool.
1889 * Modified backend interface. Request/Response struct's replaced by
1890 one read/write C struct. For example bend_fetchrequest and
1891 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1892 Every handler - even search has to be registered in bend_init
1893 handler. This means that the YAZ library no longer refers to
1894 external functions and it makes it possible to make the whole
1895 thing a single DLL/SO.
1897 Added Segment handler for backend server.
1899 Added Zmbol/Zebra administrative functions to YAZ client.
1901 Threaded frontend server on UNIX (when POSIX Threads are available).
1902 Starting the server with option -T enables multi-threading.
1906 Added configure option --enable-comp/disable-comp to control use
1907 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1908 located in sub directory asn.
1910 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1911 in ${exec_prefix}/bin along with the other programs yaz-client and
1914 GNU automake used to maintain makefiles.
1916 Added several OID's.
1918 Changed retrieval module so that we can load records with no abstract
1919 syntax defined. Tagpaths in these records are fully composed of string
1922 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1926 On UNIX, the generated makefile now supports a proper 'make install'.
1927 The prefix can be set via GNU configure to set the install location
1928 (default is /usr/local).
1930 * YAZ programs client and ztest were renamed to yaz-client and
1931 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1932 locations, such as /usr/bin,/usr/local/bin,etc.
1934 * YAZ Header files were moved from include to include/yaz. YAZ Header
1935 files are referred to as include <yaz/log.h> rather than <log.h>.
1936 The YAZ include path (-I ..) is therefore the same as before. Programmers
1937 should update their #include statements or use -Ipath/include/yaz
1938 instead. The main motivation for doing this change is that YAZ header files
1939 can be installed in "standard" locations /usr/include,/usr/local/include
1940 without introducing conflicts, since ALL YAZ header files are stored
1941 in subdirectory yaz (under /usr/include for example).
1943 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1944 rather than project/workspace files. We switched because project files
1945 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1948 Changed name of logging function, logf, to yaz_log, to prevent name
1949 clash with some math-log functions. The YAZ header log.h defines logf
1950 to yaz_log (#define) so there should be no incompatibilities by this
1953 Added bend_start/bend_stop handlers for server. These handler are
1954 called on start/stop of server. For windows they are called whenever
1955 a service is started/stopped.
1957 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1958 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1959 in util/yc.tcl. The auto-generated C code structures are, in a few
1960 cases, incompatible with the old decoders. There are differences in the
1961 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1962 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1963 The preprocessor variable ASN_COMPILED is defined when the compiled
1964 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1965 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1966 wish to use the old encoders/decoders you can specify --disable-yc
1969 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1970 version so that it supports both new - and old version of DB Update
1972 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1973 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1974 change. The name parameter can be set to 0 in which no name is specified
1975 for the construction. The macros odr_implicit and odr_explicit sets name
1976 parameter to zero for the construction involved. New macros
1977 odr_implicit_tag and odr_explicit_tag are similar to the others,
1978 except that a name parameter is added. For programmers' that don't use
1979 ODR they probably only need to change the call to z_APDU and z_External.
1981 Added access control facility by interfacing the TCP wrapper library.
1982 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1983 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1984 name of the daemon and enables the access control as specified in
1985 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1987 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1988 den Dool <H.M.vdnDool@kub.nl>.
1990 Added reference ID parameter to most functions in server API - refer
1991 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1993 Changed name of ccl library to libccl.a (was ccl.a).
1995 Fixed bug in decoder for Explain (Category TargetInfo).
1997 Added support for GNU readline in client. Thanks to Jacob Poulsen
1998 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2000 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2001 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2002 IMPLEMENTATION! This change was made to the development version before
2003 the ZIG decided to retract the amendment. If any users MUST be
2004 compatible with the original Update definition, PLEASE CONTACT US, and
2005 we will include a separate definition corresponding to the old Update
2006 ES. Note that because of the change to the ASN.1 of the
2007 TaskPackageRecordStructure we cannot define a single structure that
2008 will support both versions.
2010 * Added const modifier to buffer parameter for some ODR/BER encoding
2011 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2012 completeWAIS, odr_dumpBER.
2014 Fixed bug in client.c which caused a crash when a scanResponse didn't
2015 contain positionOfTerm.
2017 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2018 * will cause an error in a client if a non-YAZ target sends both a
2019 * list of Scan entries and non-surrogate diagnostics.
2021 Retrieval module enhancements. Tag sets may be typed in the reference
2022 to it. From the .abs-file the "tagset" directive takes a third optional
2023 integer type for the tag set referenced. From a .tag-file the "include"
2024 directive takes a third optional type as well. The old "type" directive
2025 in the tag set itself is still recognized but acts as the default type
2028 Backend interface change. Individual Scan terms returned from bend_scan
2029 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2030 in include/backend.h.
2032 Retrieval module enhancements. Multiple tag sets and attribute sets may
2033 be specified in abstract syntax specs. Revised the error/warning for
2034 logging messages reported by the retrieval module when reading the
2037 Object Identifier system (oid_..) changed. The API is backwards
2038 compatible but the oid-routines now allocates new OID's when needed.
2039 Raw OID's may be specified in oid_getvalbyname.
2041 YAZ now uses GNU configure to generate Makefile(s).
2043 * Minor changes in some of the member names of DeleteResultSetRequest and
2044 DeleteResultSetResponse. See include/proto.h.
2046 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2047 and added member 'languages' in TargetInfo (which was missing).
2049 Changed the way attribute sets are handled in the retrieval
2050 module. These are now cached, just like the abstract syntaxes
2053 Changed YAZ so that it links with compiled ASN.1.
2055 Added Explain-schema definitions and mapping routines. The following
2056 Explain categories have been implemented: AttributeDetails,
2057 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2059 Fixed minor bug in Windows version of Server Library.
2061 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2063 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2065 Added EXTERNAL: UNIverse Resource Report (non-standard).
2067 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2068 ENUMERATED and SET OF.
2070 * Added 'const' to some of the char pointer arguments for the
2071 functions, data1_read_node, data1_getelementbytagname,
2072 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2075 Fixed bug in data1_insert_taggeddata - the last_child member of
2076 parent wasn't initialised.
2078 * Changed data1_read_record and data1_read_node so that the supplied
2079 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2080 doesn't refer to any parts of the "SGML"-buffer.
2082 Fixed bug in server library (Windows version of statserv_remove).
2084 * Changed code so that it compiles as C++. The type definition
2085 of Odr_fun which is a member of Odr_arm was changed. The result is,
2086 that an explicit typecast is needed for the fun pointer when
2087 using Odr_arm - as in:
2088 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2090 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2092 Implemented the new structured date and time definition as approved
2093 by the ZIG. Added schemaId element to the specificTag in Espec-1
2094 (also approved at the last ZIG). Thanks to RVDM.
2096 Added some Object identifiers (RVDM).
2098 Changed the Update Extended Service (RVDM).
2100 Added command "refid" to client which specifies referenceId for
2101 the following requests.
2103 Implemented extended service handling for server. See ztest.c
2104 for an example as well as backend.h. New handlers are registerd
2105 in the Init handler.
2107 * Changed interface for sort in server.
2109 Added new members to statserv_options_block. It allows a server
2110 to read options from another source than just the command line. Thanks
2111 to Charles Woodfield.
2113 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2114 renamed to zboolean. Some C++ compilers complained about the name.
2116 Minor changes to gils.abs. Added index 's' (sort) on title
2117 and date/time-last-modified.
2119 --- 1.4pl2 1998/1/30
2121 Fixed bug in server library regarding inetd mode (-i). This bug
2122 was introduced by release 1.4.
2124 --- 1.4pl1 1998/1/29
2126 Added sort facility in client and backend server interface.
2128 Fixed problem with dependencies in Makefile(s).
2130 Fixed bugs for encoders/decoders of extended services and
2133 Implemented sub-tree feature for schemas. Sub-trees are
2134 referenced in *.abs-files. See explain.abs for an example
2135 of the use of this feature.
2137 Modified bib1.att; local attributes for ANY didn't include
2138 ANY itself (only affects use of the retrieval module).
2140 Fixed bug in plain SGML reader in function data1_read_node:
2141 tags with prefix "var" was incorrectly interpreted as variants.
2143 Added feature "sub-schemas" to enable references to - and definitions
2144 of - group of elements.
2146 * Removed member parent from type data1_element (in data1.h).
2148 Implemented function odr_nullval() that returns the value of
2151 * Removed member num_children from data1_node (in data1.h).
2153 Made NT service interface part of the server library. The
2154 function statserv_main uses the NT service when required and
2155 calls the statserv_start / statserv_close routines.
2157 Routine zget_SearchRequest and zget_PresentRequest fills
2158 resultSetName/Id member with "default" instead of "Default".
2160 Fixed memory leak in server. Request queue member wasn't freed.
2162 Fixed nmem_exit so that memory is freed.
2166 Revised the CCL parser utility to be thread safe.
2168 Added function, oid_ent_to_oid, to replace the function
2169 oid_getoidbyent, which is not thread safe.
2171 * Added nmem_init and nmem_exit to initialize and release
2172 NMEM resources. Function nmem_init should be called once in the
2173 initial thread before NMEM/ODR is used. statserv.c and client.c
2174 have been changed accordingly. The change was necessary to make
2175 NMEM thread safe. The NMEM memory pool is shared amongst threads
2176 in a process. Unix-based applications will still work fine without
2179 Added NT Services interface for the the Z39.50 (statserv) Server.
2180 Refer to the ztest.c source on the usage.
2182 Windows 95/NT port using MSVC5.0. Project files are included in the
2185 * Defined new 'global' handle for the retrieval (data1) system. The
2186 new handled, data1_handle, describes the state of the data1 system.
2187 This handle is passed as first argument to virtually all
2188 data1 related routines. The functions data1_create and data1_destroy
2189 creates and destroys a data1 handle respectively.
2191 Added ODR encode stream member to all backend request structures
2192 init, search, scan etc. This stream should be used to allocate all
2193 memory used for the response when thread safe operation is needed.
2195 Changed the comstack utility, cs_addstr, to be thread safe. The
2196 returned hostname string returned by the function is now part the
2199 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2200 function. The cs_straddr takes a COMSTACK handle as argument, so this
2201 function must be used after cs_create and before bind/connect.
2202 This function is thread safe.
2204 Moved test server to 'ztest' directory - generic server code still
2205 in 'server' directory.
2207 Made prefix query (pquery.c) utility thread safe.
2209 Added new function modifier YAZ_EXPORT to 'export' public DLL
2210 functions when using windows (see include/yconfig.h).
2212 Added definitions to the OID database (util/oid.c) (RVDM).
2214 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2216 Added call to ccl_rpn_delete in client program.
2218 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2219 release of RPN structure.
2221 Added support for C++, headers uses extern "C" for public definitions.
2222 With input from RVDM.
2224 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2225 Thanks to Ronald van der Meer (RVDM).
2227 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2229 Added support for private extensions to the OID database
2230 (oid_setprivateoids()). Thanks to RVDM.
2232 Added optional, physical ANY (key replication)
2234 Fixed null-reference problem in GRS-1 output filter.
2236 Proximity operator added to Prefix Query Format (PQF).
2238 In test client command "base" accepts multiple databases.
2240 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2244 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2246 Smallish bug-fixes in the new encoders/decoders (explain).
2248 Bug fixed in DeleteRequest.
2250 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2252 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2254 Added SOIF syntax (using private OID for now) to retrieval module and client.
2256 Added Update extended service.
2258 Added SearchResult-1 additional info structure.
2260 Added optional CCL (ISO8777) interpreter as separate module. Available
2263 --- 1.2 1996/6/10 (1st anniversary release)
2265 Added Summary record syntax. Lightly tested.
2267 Added OPAC record syntax. Untested.
2269 Added ResourceReport service encoders/decoders. Untested.
2271 Fixed bug in z_Unit - wrong tagging on unitSystem.
2273 Fixed bug in the DiagRecs decoder.
2275 Added options for max PDU size and session timeout to frontend-server.
2277 Added documentation of query-language parsers and other supporting utilities.
2279 [frontend-server] Added Attribute set to the bend_scanrequest API.
2281 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2282 surrogate diagnostics were generated.
2284 [retrieval] Allow multiple local values for attribute.
2286 [retrieval] Allow multiple attributes per element in .abs files. index type.
2288 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2290 --- 1.1pl2 1996/4/10
2292 Minor changes, mostly specific to Zebra's requirements (retrieval)
2296 Repaired bug in frontend server when running multiple listening
2297 endpoints in dynamic mode.
2299 z_External() now won't break if a known, ASN.1 value comes encapsulated
2300 in an octet-string. The value will pass through unmodified in an Odr_oct.
2302 Added a bit of code to the demo client to decode & display
2303 ASN.1-structured records represented in the octet-aligned branch of
2304 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2306 Added z_ext_getentbyref() to the ASN module. Doc updated.
2308 * Completed the SCAN definition in the ASN module. This may break SCAN
2309 code based on older YAZ-versions at compile-time. The fix is easy -
2312 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2313 under the SCAN definition. Remember to initialize this, server-people.
2315 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2316 that this does not extend to ODR and ASN.
2318 Comstack allows insertion of established socket (primarily for
2319 inetd-operation of servers). Doc updated.
2321 Front-end server can now start from the inetd in TCP mode. Doc
2324 --- 1.0pl4 1996/1/24
2328 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2329 the rank and record number.
2331 Adjustments to the frontend server.
2333 Fixed diagnostic BER dumper. It ignored the file argument.
2337 Various changes to retrieval module.
2339 Changed the union discriminators of the protocol files from enums to
2340 ints paired with #defines.
2342 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2345 *Changed operator in the RPN structure to 'roperator', again to avoid a
2348 Fixed problems in Explain decoders/encoders.
2350 --- 1.0pl2 1995/12/6
2352 Memory bug in log module fixed.
2354 --- 1.0pl1 1995/12/5
2356 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2358 Bug in Explain DatabaseInfo module fixed.
2360 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2364 The shift to v1.0 signals that we now consider the *core* functionality
2365 of YAZ reasonably stable (the core being more or less equivalent to
2366 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2367 tested (Explain not at all - though that will happen soonish).
2369 Minor changes to code to support Windows port.
2371 Various minor changes after we're getting to use GRS-1 & co. more.
2373 Added Espec-1 format.
2375 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2376 of the protocol and it cannot be selected when encoding (maps into 'string'
2377 when decoding). Needed to talk to some servers.
2379 Demo client can request simple element set names.
2381 Added Diagnostic Format encoders/decoders.
2383 Added simple Close handling to frontend server (no hooks for resource
2384 reporting yet), and demonstration client.
2386 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2388 --- 1.0b3 1995/08/24
2390 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2391 handled incorrectly when records were requested in the searchResponse. This
2392 will only affect you if you use the frontend-server.
2394 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2395 Test-client will ask for and print GRS1. Ztest will return dummy records
2398 Added Explain encoders/decoders to the service-level API. Untested.
2400 Added Extended Services: Item Order encoders and decoders to the Service-
2401 level API. Untested. We could use a recent copy of the pertinent bits
2402 of the ILL protocol to add those bits.
2404 Added diagnostic format 1 encoders/decoders to the service-level API.
2407 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2408 odr_cons.c, which causes a more correct output.
2410 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2411 was always set to 0 when no records were requested in the searchRequest.
2413 * Added better external-handling. This shouldn't harm old code that
2414 *encodes* externals. It can break code that looks for a
2415 'single-ASN1-type' representation, since those types that are known
2416 are now decoded immediately. Look at the SUTRS sample code in
2417 seshigh.c and client.c. Documentation updated.
2419 Handling of structured records in bend_fetchresponse. Length -1 marks
2420 structured record, type is deduced from format field.
2422 --- 1.0b2 1995/06/27
2423 Fairly quick maintenance release to add SUTRS support.
2425 Fixed handling of SUTRS records in the demonstration client.
2427 * Added format field to the bend_fetchrequest and bend_fetchresponce
2428 structures of the backend API (frontend server). When the record is
2429 returned, the value of the format field is mapped to an OID. The
2430 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2431 of the record. The special value VAL_NONE in the bend_request means
2432 that no specific format was requested by the client. Documentation
2433 updated accordingly. Test server (ztest) will return a fixed dummy
2434 SUTRS record if your client requests SUTRS.
2436 Documentation updated accordingly.
2438 You can now set external libraries and RANLIB support in the top-level
2442 First public release.
