3 Added yaz_daemon (daemon.h).
5 Fixed bug #2068: pkg-config trouble
7 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
11 Document --with-xml2 option.
13 Added OPAC XML XSD (etc/opacxml.xsd).
15 Allow glob mask for name attribute in retrieval element for the
16 generic frontend server's retrieval facility.
18 Changed yaz_poll_poll to return yaz_poll_except for all returned events
19 except POLLIN/POLLOUT.
21 Fixed error handling in cs_listen. Bug #2037.
25 Fixed version in yaz/yaz-version.h.
27 Fixed bug #2027: Crash when closing connection.
29 Changed configure so that ICU support is only enabled if only ICU
30 and Libxml2 is available (because the ICU chain is XML based).
34 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
35 is built. Only this DLL depends on the ICU runtime.
37 yaz-ziffy is no longer part of YAZ. It is distributed separately by
38 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
40 Changed license of CCL module to 'Revised BSD'. After consultation with
41 remaining members of the original EUROPAGATE consortium, we are re-issuing
42 the CCL module without a separate license. The software was developed by
43 Index Data as part of a research project. The special license was included
44 to help feed usage information back to the project consortium to support
45 project evaluation. At this time, the project consortium has long-since
46 disbanded, and the majority of the original principals have retired. At the
47 same time, we have significantly modified the software during the following
48 years, to the point where very practically no original code remains. To
49 simplify re-use of the software, we have contacted those members of the
50 consortium who could be reached, and agreed to re-issue the module as a
51 proper part of the YAZ package.
53 Tcl scripts uses /usr/bin/tclsh as preferred shell.
55 CQL closer to being version 1.2 compliant. CQL also allows free-form
56 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
59 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
60 bug could make Extended services handling crash in the ZOOM layer. This
61 bug was only present in YAZ 3.0.18.
65 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
68 yaz-marcdump reads and writes collection wrapped records.
70 Handle OPAC for record conversion module.
72 Fixes for ICU wrapper.
74 Allow ICU libs to be controlled with --with-icu .
78 Added yaz_poll which is a wrapper for select/poll. When poll is available
79 and non-buggy, it is used, by yaz_poll . This allows more than 1024
82 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
83 functionality through an XML based configuration (ICU chain). This system
84 is useful for search facilities such as Pazpar2 and Zebra that needs to
85 perform tokenization of indexed material. The ICU code in a separate
86 library libyaz3_icu.a.
88 Added HTTP tunnel facility for COMSTACK, bug #1752.
89 This is a facility that allows a Web proxy, such as squid, to tunnel
90 Z39.50 traffic. This facility is "transparent" to must applications
91 using YAZ. It's enabled by using pseudo transport connect: followed by
92 the proxy address, followed by command, then follwed by he regular
93 "virtual" addresss. For example,
94 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
96 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
100 Fixed bad memory reference in ZOOM_record - cuased by member not being
101 initialized. This was a problem only in YAZ 3.0.12.
103 Fixed bug in conversion from MARC to XML: Non-XML characters in control
104 fields were not removed.
106 Changed the way C code is generated from codetables.xml. Made a MARC-8
107 conversion trie for each characterSet section rather than codeTable.
108 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
109 of codetables.xml from Larry Dixson, LOC. Bug #1464.
111 --- 3.0.12 2007/09/12
113 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
114 from ZOOM_record_error).
116 ZOOM C function ZOOM_record_get returns record schema for type="schema".
118 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
120 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
122 Better SRW-to-Bib-1 diagnostic mapping.
124 ZOOM C and yaz-client announces SRU version 1.2 by default.
126 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
129 Fixed in yaz_sru_decode to allow other version than 1.1.
131 --- 3.0.10 2007/08/22
133 Added support for SRU scan for ZOOM.
135 Added support for the use of the older versions or Extended Service
136 Update in ZOOM. To faciliate this, an option "updateVersion" may be
137 set to the version , 1=first, 2=second, 3=third. The third version is
138 what ZOOM C has used so far. And that, obviously, is the default.
140 Added support for CCL queries in Z39.50 queries sent to the GFS (and
141 therefore in Zebra and in SimpleServer-based applications). The new
142 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
143 qualifier file used to transform incoming CCL queries into Type-1 RPN,
144 which is passed into the back-end search callback function.
146 Added support for HTTP Basic authentication in clients: the SRU/W
147 codec encodes the username/password elements of the PDU structure
148 appropriately, and these may be set using the "user" and "password"
149 options in ZOOM-C applications (the same options that are used for
150 Z39.50 authentication).
154 Fixed bug #1208: SSL appears to be broken in ZOOM.
156 Fixed bug #1206: Libxml2 include path weirdness.
158 Added oid_name_to_dotstring.
160 Allow elementSetName to be specified for ZOOM C record update.
162 Allow waitAction to be specified for ZOOM C based for Extended Services.
164 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
165 syntax OID. Bug introduced in YAZ 3 series.
167 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
171 Fixed bug #1157: yaz-client does not read .yazclientrc from current
172 directory. yaz-client now reads commands from file given by option -f
173 if specified; then tries to read .yazclientrc in current directory.
174 Failing that, it reads .yazclientrc from user's home directory.
176 Added support for correlationInfo Note and ID for Record Update via
179 Added yaz-client command querycharset which specifies character set for
180 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
181 (termListAndStartPoint).
183 Charset ISO5428:1984 is an alias for ISO5428-1984.
185 Implemented a way to perform scan in a result set using Z39.50. This
186 is achieved by attaching the result set name in the characterInfo
187 (type InternationalString) of OtherInformation in the Scan Request PDU.
188 The result set is identified in the otherinformation by the new OID:
189 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
190 This allows for scan in result set and faceted search . Zebra did some
191 of this in the APT term using attribute type 8 and value being result
192 set. Using the OtherInformation approach for this is cleaner and easier
193 to work with in proxies and the like. This facility can be used in
194 yaz-client using new command setscan which takes a result set as first
195 argument, start position (APT) as second.
197 Changed decoding of SRU XML packed records to deal with servers that
198 have recordData with XML data with multiple root nodes. Also make
199 comparison for recordPacking case insensitive. Again, one server
200 returns "XML" where others return "xml".
202 For SRU responses allow Content-Type application/xml as well as text/xml.
206 Fixed bug in character set conversion of BER strings. Bug introduced
211 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
213 For OID class, use oid_class consistently.
215 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
218 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
219 character set for bibliographic information interchange". By Giannis Kosmas.
221 Added documentation on new OID API.
225 Changes to generic frontend server interface: added new member
226 'query_charset' for bend_initrequest structure. A backend init handler
227 should set this member to its native character set for query terms.
228 When defined, the frontend server logic will announce this character set
229 to a client if the negotiationModel bit is set by the client. All server
230 implementors are encouraged to specify this. If a backend server does not
231 specify this a warning is issued using yaz_log(YLOG_WARN,..).
233 Added CCL utility to remove terms (stop words) from resulting RPN
234 tree. This is handled by functions with prefix ccl_stop_words_ .
236 New ZOOM C option, "rpnCharset", which allows client-side conversion of
237 terms in RPN queries.
239 Clean-up the CCL API. Moved some internal structures from ccl.h to
240 private header cclp.h. Changed ccl_parser_create so that a Bibset must
241 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
242 This is replaced by ccl_parser_find_str which takes a string instead.
244 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
245 libyaz.la is the core of YAZ except the generic frontend server and
246 does not depend on POSIX threads anymore. libyaz_server.la is the
247 generic frontend server facilities and uses POSIX thread functionality
248 if available. The libyaz.la no longer depends on POSIX threads because
249 the number of global structures is limited. NMEM no longer re-uses blocks
250 between threads ; it simply free's memory immediately but allocates in
251 "large" chunks as usual. We don't expect any performance penalties
252 because of this. The yaz_log system is still using a global log_level so
253 caution must be taken when modifying it with yaz_log_init_.. +
254 yaz_log_mask_str. This, however, should not cause any trouble because
255 these functions are called during initialization of application code
256 anyway. `yaz-config --libs server` returns libs for server applications;
257 `yaz-config --libs` returns libs for non-server applications.
259 New OID database - with public definitions in oid_db.h. Removed old OID
260 database including the head oid.h and definitions such as enum oid_value
261 and struct oident. The new OID database uses the same string names as
262 before but the 'protocol' is gone. There are now only two representations
263 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
264 converts from string to OID; functions with prefix yaz_oid_to_string
265 converts the other way.
267 Change to emit_term() in CQL-to-PQF query translation: when a term has
268 the /regexp relation modifier, do not process it for leading and
269 trailing "^" and "*", which have quite different meanings in regular
272 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
273 write handlers no longer carries a 'last' parameter. This will make
274 yaz_iconv flush "less" characters. A flush is performed by call to
275 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
277 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
278 removed, because function yaz_query_to_wrbuf does the same.
280 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
281 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
283 Deprecated MARC utility functions removed.
285 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
288 Branch split: YAZ_2_1_55_branch
290 --- 2.1.54 2007/03/16
292 Fix to ZOOM-C so that transparent reconnection is properly handled on
293 connections that are in asynchronous mode.
295 Fixed compilation on OpenBSD 4.0.
297 Large strings in GRS-1 records are now properly displayed in yaz-client.
299 Added character conversion support for "advancegreek"; based on patch from
302 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
303 sequence is met. Before the error was not set so it would be unknown.
305 Adjust yaz-marcdump MARC reader so that it skips until record separator
308 --- 2.1.52 2007/03/07
310 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
311 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
312 fd_set structure used as a bitmask for the FDs to be selected on.
314 Using ACX_PTHREAD macro to check for POSIX threads.
316 Fixed have-vsnprintf check.
318 --- 2.1.50 2007/02/23
320 Fixes for configure on BSD. Bug #900.
322 Added snprintf/vsnprintf wrappers for systems that don't have
323 limits (heavens forbid).
325 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
326 created before all previous tasks were completed and removed from the
327 task queue, the new task could be removed by a mistake.
329 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
331 Implemented pass-through CQL-to-PQF conversions. Bug #861.
333 Fixed bug #832: Problem with MARC/charset in yaz-client.
335 Fixed bug #668: save command line history for yaz-client.
337 Fixed bug #830: pkg-config support.
339 --- 2.1.48 2007/01/23
341 Extended ZOOM result set options with two options that may be read by
342 a client: resultSetStatus and presentStatus with values as specified for
344 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
346 Fixed bug #827: Using SSL fails on Debian etch.
348 Fixed bug #826: Weird looking chars for set of MARC records.
350 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
351 that is treated as an ItemOrder with itemRequest being an XML document
352 external. The value of "doc" is the content.
354 Extended the GFS search facility. New member of bend_search_rr
355 'estimated_hit_count' signals that hits is known to be an estmate
356 (higher or lower than real hit count). New member 'partial_resultset'
357 signals that the search was partial (hit count is lower or equal than
358 real hit count). For Z39.50, the information is stored in resultSetStatus
359 member of SearchResponse APDU. For SRU, the information is signalled
360 via SRU diagnostic 59: "Result set created with valid partial results
363 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
365 --- 2.1.46 2007/01/13
367 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
369 Added ZOOM_connection_peek_event.
371 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
372 the following new functions:
373 ZOOM_event_nonblock, ZOOM_connection_process,
374 ZOOM_connection_get_{socket,mask,timeout},
375 ZOOM_connection_fire_event_{timeout,socket}.
376 The existing blocking event handler, ZOOM_event, is a wrapper for the
377 + blocking ZOOM_event_sys_{poll,select}.
379 Implemented function ccl_xml_config which parses XML version of CCL
380 configuration (bug #798).
382 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
384 Added timings utility (yaz/timing.h)
386 --- 2.1.44 2007/01/03
388 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
391 Fixed bug #779: Rotation of apdu.log fails.
393 Fixed for character set conversions:
394 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
395 Honor G1 set in MARC-8 decoding.
397 --- 2.1.42 2006/12/17
399 Fixed bug #775: char conversion does not handle Alternative UTF-8
402 Implemented function yaz_marc_read_line which parses MARC line format
403 records. There is a wealth of formats out there. So far, this function
404 reads line records produced by yaz_marc_write_line.
406 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
407 more generic and easier to remember(!) options: -i format and -o format
408 which specifies input format and output format respectively - where
409 format is one of "marc", "marcxml", "line", "marcxchange".
411 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
412 does not print anything except warnings for records.
414 For yaz-marcdump, added support for MARC split into files (-s) with a given
417 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
418 spec, at http://www.loc.gov/standards/sru/record-update/
419 This has changed the binary layout of the following structs:
420 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
421 bend_update_rr . Patch by Ko van der Sloot.
423 Added GFS utility function bend_assoc_is_alive which returns 1 if
424 association is still alive (client is connected); 0 otherwise (client
425 closed connection). This allows busy servers to stop working for
428 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
429 been a separate piece of software. This version of ziffy has been modified
430 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
432 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
434 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
435 Client code may now interrogate options such as "init_opt_sort" to
436 find out whether the server claims to support various options.
438 --- 2.1.40 2006/11/27
440 Added utilities yaz_{set,get}_esn to set/get element set name from
443 Removed the build of libyazthread.la. The libyaz.so is the threaded version
444 of YAZ and has been so since YAZ 2.1.10.
446 Implemented ZOOM_record_error which returns error information for
447 record (surrogate diagnostic).
449 --- 2.1.38 2006/10/31
451 Updates for SRU Update by Ko van der Sloot:
452 1. Changed name from "operation" to "action"
453 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
454 versions in the code, marked as 'backward compatible'.
455 3. Added diagnostics for SRU Update.
457 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
459 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
461 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
463 For GFS, fixed problem with SRU diagnostic 'First record position out of
464 range' being issued for 0 hits.
466 zoomtst10 part of Windows Build.
468 --- 2.1.36 2006/10/13
470 Implemented yaz_filepath_comp which splits a path into file path
471 components (required by Zebra 2.0.3+).
473 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
474 BSD inspired license until now so this should not have any real impact on
475 anybody. See http://www.opensource.org/licenses/bsd-license.php
477 Fixed bug #687: Missing log lines.
479 Fixed bug #678: CQL to PQF translation does not preserve double-quote
482 Fixed bug #689: SRU diagnostics to be added.
484 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
485 whether a connection is idle (no more work do do).
487 --- 2.1.34 2006/10/04
489 Change type of optval from long to int for invocation of setsockopt with
490 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
492 Added support for specifying the max log file size for the Generic
493 Frontend Server. The size is given with option -r.
495 --- 2.1.32 2006/09/21
497 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
499 --- 2.1.30 2006/09/17
501 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
504 Fixed bug in Generic Frontend Server that could cause a server to stop
505 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
507 For the generic frontend server, the maximum record size is used as maximum
508 size of incoming packages (SRU + Z39.50). The value until was previously
509 only used in Z39.50 Init negotiation and, later, in a session controlled
510 sizes of records returned. This is controlled using -k option. It can be
511 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
513 --- 2.1.28 2006/09/04
515 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
518 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
520 New option for yaz-marcdump -lpos=value which allows setting a portion
521 of MARC header to a certain value.
523 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
525 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
526 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
528 --- 2.1.26 2006/08/15
530 Fixed problem with SRU mode type (soap, get, post) for yaz-client
533 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
535 --- 2.1.24 2006/08/08
537 Fixed MARC ISO2709 encoding routines to deal with character set
540 Minor changes to GFS logging. Database included in search request log
543 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
544 cached/multiple records.
546 Shared libraries are built by default on Unix+configure.
548 Changed cql2pqf transformation to use a different evaluation order. The
549 new order is: always, relation, structure, position, truncation, index
550 and relationModifier. Old order was: always, relation, relationModifier,
551 structure, index, position, truncation. Note that the the latter ones
552 override former ones for identical attributes.. The new scheme means that
553 it is possible to override any existing attribute with a relationModifier.
554 And also that it is possible to override everything for the index rule
555 (except the ones listed in relationModifier). No order is perfect but this
556 one, we believe, covers more real cases.. The "always" should have been
557 called "default", since the attributes there can be overridden with all
560 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
561 compilation phase, but also for yaz-config --cflags output. This allows
562 us to have public headers with Libxml2 stuff in them . It should also,
563 eventually, make Libxml2 checks redundant in packages using YAZ, such
566 --- 2.1.22 2006/06/15
568 Changed SRU update structure bend_update_rr so that SRU diagnostics are
569 stored in uri, message and details.. Previously diagnostics were stored
570 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
571 compatibility.. but he's probably the only one affected, so.
573 Added support for CCL, compiled on the client side, in ZOOM-C. This
574 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
575 input; the resulting query objects can be used for for searching with
576 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
578 YAZ' configure searches for OpenSSL by default.
580 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
581 SL_CTX_use_certificate_file. See
582 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
583 for more info. Thanks to Ko van der Sloot.
585 --- 2.1.20 2006/06/02
587 Bug #600: SRU GET, POST support for yaz-client. Introduced
588 command 'sru' which selects method SOAP/GET/POST.
590 Allow missingValueAction to be specified for the sortspec string -
591 function yaz_sort_spec. By default, the missing value action is null.
592 Use ! to specify "abort". Use = followed by stringvalue to specify default
595 Ensured that Present-handler (if defined) is called in GFS before any call to
596 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
597 searchRetrieve requests.
599 Documentation for YAZ is now based on the Docbook XML/XSLT using
600 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
601 is no longer depending on jade/openjade or docbook-to-man scripts.
602 PDF is no longer part of the distribution - but can optionally be
603 made using DSSSL/jadetex or FOP.
605 Added retrieval handling support in Generic Frontend Server to support
606 conversion between MARC/XML as well as XSLTtransforms. See
607 etc/yazgfs.xml for an example.
609 Added Authentication support to Generic Frontend Server in SRU
610 mode. Authentication using HTTP Basic is supported, as is the use
611 of 'x-username' and 'x-password' parameters in the request itself.
613 Added support for a new character set MARC8s identical to MARC8 except
614 that it converts combined characters to single Unicode characters in the
615 Latin-1 range (when possible).
617 --- 2.1.18 2006/04/24
619 ASN.1 compiler 0.4: generates brief Doxygen file header for
620 generated .h/.c files.
622 Utility yaz_iconv now supports conversion to MARC-8.
624 New facilities for the MARC module. The reading - and writing of
625 content are separate methods for the yaz_marc_t handle. The following
626 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
627 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
628 format). Write functions have prefix yaz_marc_write_.. The existing
629 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
630 available. Removed support for OAI-MARC and simplexml (not the
631 simplexml from PHP5).
633 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
634 to be returned for this connection.
636 --- 2.1.16 2006/03/31
638 Allow multiple languages and charsets to be specified with
639 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
640 negcharset iso-8859-1,utf-8
642 Translation of proximity nodes from CQL into PQF now works.
644 Moved to automake 1.8, 1.9.
646 Added function yaz_log_set_handler which allows a log handler to be
647 installed. This handler will be called for all log messages. Output
648 to file is also produced; but that can be disabled by passing NULL
649 fname to yaz_log_init_file.
651 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
653 For SRW (including GFS), accept application/soap+xml as content-type
656 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
657 produces NO stylesheet reference even if a default stylesheet is specified
660 --- 2.1.14 2006/03/14
662 Updated Windows package to include yazd.dll + yazd.lib for the
663 Development component.
665 If the environment variable YAZ_LOG is set, then it is used as a
666 string indicating the default level of logging to use if not
667 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
668 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
669 used as before. So, for example, to omit warnings from YAZ logging,
672 cql_transform() now map structure and other attributes before indexes,
673 so that index-specific structures and other attributes can override
674 defaults. So now a combination of mapping specifications such as:
676 index.dc.date = 1=date-modified 4=5
677 does the right thing.
679 cql_transform() now also respects the "always" mapping specification,
680 which establishes an initial set of attributes to be used for all
681 terms except where overridden by more specific attributes associated
682 with the index, relation or modifier.
684 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
685 which mode to use; one of "post", "get" or "soap" (SRW, default).
687 Fixes for yaz_iconv routines: changed trie-based character set conversions
688 to use only non-negative values for bit fields due to Sun's C compiler not
689 supporting negative values.
691 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
692 sequences where not read correctly. Fix by Rustam Usmanov.
694 Updated win/makefile to use options, settings which makes things
695 compile with VS C 2005.
697 --- 2.1.12 2006/02/01
699 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
701 In ZOOM socket code, use select instead of poll on MacOSX.
703 ZOOM-C now support client-side compilation of CQL into RPN that is
704 sent to the server, enabling CQL to be used against all Z39.50
705 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
706 ZOOM_query object, and submit it using ZOOM_connection_search().
707 The CQL-to-RPN translation uses a configuration file, the name of
708 which must be specified in the Connection's "cqlfile" option.
710 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
711 function, which takes as its start-term parameter a ZOOM_query object
712 (which may have had either CQL or RPN set into it).
715 --- 2.1.10 2005/11/29
717 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
718 GFS to support this as well. Backend handler, bend_srw_update, does the
719 update work. Code contributed by Ko van der Sloot.
721 Allow retrieval of Search Result-1 information in ZOOM by the use of
722 options that are attached to a result set. ZOOM documentation updated
725 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
726 UTF-8 conversion. Patch by Raj Patel.
728 Added option -m to GFS to control formatting of timestamps in log file.
730 Added 'exit' as synonym for 'quit' in yaz-client
732 Added support for specifying SRW resultSetId + resultSetIdleTime in a
733 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
734 for the new members. Patch by Ko van der Sloot.
736 Added support for SRU POST. It is supported for content-type
737 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
739 Do not build the separate Multi-threaded (MT) library libyazthread.la.
740 Instead make the library libyaz.la multi-threaded. Threading as a whole
741 can still be disabled by configure option --disable-threads. Previosly,
742 with older GLIBCs there were problems with MT libs under Apache. This
743 has now been fixed a long time ago.
745 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
748 CQL module modified to be case insensitive for relations/indexes/operations.
750 Fixed bug in CQL transform code: incorrect value relationModifieder
753 Added 'show all' command for yaz-client which retrieves all results
756 Added new yaz-client, xmles, which takes a (private) OID and
757 a document to be sent as an extended service request.
759 Describe new yaz-client commands wait_response and set_auto_wait.
761 Increase TCP/IP listener backlog from 3 (which I am guessing was
762 copied from the SunOS manual entry way back when) so SOMAXCONN, so
763 that the socket will queue as many incoming connections as it's able
764 to handle ongoing connections. In other words, it will never now
765 refuse a connection that it would be able to handle merely because
766 it's not got around to accepting() enough of the pending connections
767 yet. This is the behaviour anyway under Linux, where the listen()
768 argument is ignored; but not under BSD and on systems such as
769 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
770 YAZ-based servers should now be uniform across operating systems in
773 yaz-marcdump uses 64-bit file access on some systems. This is enabled
774 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
775 This allows yaz-marcdump to read large MARC batches (>2 GB).
777 Modified all YAZ source files - except the source which is auto-generated
778 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
781 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
782 corresponding to the existing *_setl() function. These allow option
783 values containing arbitrary valuues.
785 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
786 ZOOM_resultset_sort() in new applications. Its behaviour is identical
787 except that it returns an indicator of whether or not the sort
788 criterion was accepted (0 for OK, -1 for invalid).
792 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
793 MARC output rather than returning "new" buffer.
795 yaz-client warns about unknown init options.
797 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
801 Added support for SRW sort in Generic Frontend Server. Patch
802 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
803 sortKeys - or NULL if none is provided.
805 Fixed bug #307: It was impossible to specify indefinite/no timeout
806 for ZOOM_event. Special timeout value -1 now means indefinite timeout
809 Added support for multiple languages and charsets to be specified in
810 ZOOM. Each charset/language is separated by a blank. If negotiation is
811 in effect in init-response, Option
812 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
813 Code based on patch by Vasiliy Osadchuk.
815 Fixed bug #306: infinite recursion that occurred when calling
816 yaz_log_level_init as the first call (before other log level or
819 Fixed bug in scan handling in front end server: if preferred-Position-In-
820 Response was non-present, a NULL pointer referece was performed.
824 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
825 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
826 now defined for all those error codes. So instead of putting 109 in
827 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
828 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
830 Modified the yaz-marcdump utility to skip garbage bytes between MARC
833 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
835 Program yaz-client now exits and produces an error message if multiple
836 Z39.50 servers are specified on the command line (none or one allowed
839 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
844 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
846 Fixed bug #272: Preserve spacing for CCL terms.
850 Added support for virtual hosts and multiple backend servers for
851 the YAZ frontend server. The configution is XML based and
852 support specificition of CQL to RPN mappings and explain information.
853 See section "Virtual Hosts" in the YAZ manual.
855 Extended OPAC display utility. OPAC display utility renders
856 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
857 to supplement yaz_marc_decode_wrbuf.
859 Fixed a bug in MARC decoder that could caused it to crash for some
860 invalid MARC records. More diagnostics and warnings where added in
861 XML output (warnings, etc are stored in comments).
863 --- 2.0.34 2005/02/08
865 Fixes for UNIX domain sockets. Bug #261.
867 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
869 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
870 Added yaz_marc_subfield_str which defines subfield lead string which is
871 used in YAZ_MARC_LINE format. Default string is blank+$. Added
872 yaz_marc_endline_str which defines end of fields string used in
873 YAZ_MARC_LINE format. Default string is newline.
875 Experimental support for MarcXChange. This format can be produced
876 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
877 http://www.bs.dk/standards/MarcXchange.xsd
879 Added yaz-client commands scansize that sets maximum number of
880 entries to be returned by scan.
882 --- 2.0.32 2005/01/11
884 Added support for SRW scan in yaz-client and Generic Frontend Server.
886 * Added whereInList member to SRW Scan Term.
888 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
890 Fixed NMEM system to return aligned blocks on the smallest boundaries
891 that are suitably aligned for all possible types on the particular
892 architecture YAZ is being built for.
894 --- 2.0.30 2005/01/04
896 Fixed numerious warnings that was issued with newer versions of GCC.
898 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
899 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
902 Make YAZ Generic Frontend Server slightly faster.
904 Enhance (and reduce) logging for Generic Frontend Server.
906 Revert YAZ log system so that it flushes every write operation
907 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
909 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
910 instead of LOG_, due to name clash with syslog(3). LOG_ are still
911 present. New applications should define YAZ_USE_NEW_LOG=1 - this
912 will effectively disable old definitions.
914 --- 2.0.28 2004/11/09
916 Added yaz_log_time_format which specifies log format using
919 Added yaz_log_module_level which returns mask for a module. Value
920 is non-zero mask a if module is enabled; zero if disabled.
922 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
923 in include/yaz/cql.h.
925 Fixed bug #176: Dont throw diagnostics on empty SRU args.
927 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
929 Fixed bug #172: RPM builds does not enable SSL.
931 Doxyfile.in part of dist. Doxyfile generated by configure.
933 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
934 are given and the corresponding component does not exist.
936 Extend CCL documentation in YAZ reference. Describe r=r.
938 --- 2.0.26 2004/10/01
940 Fixed MARC->MARCXML conversion to properly deal with
941 fields, subfields, indicators having non-ASCII characters.
943 Fixed MARC->MARCXML conversion so that ASCII control characters
944 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
947 Added YAZ GFS support for conversion from Z39.50 surrogate
948 diagnostics to SRW surrogate diagnostics.
950 Bug fix: YAZ GFS did not return schema in explainResponse.
952 --- 2.0.25 2004/09/30
954 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
955 now converts recordSchema to elementSetName as well as schema URI.
957 Fixed bug in COMSTACK that prevented HTTP request packages from being
960 --- 2.0.24 2004/09/29
962 Added CCL facility r=r "range" which is similar to r=o "ordered" but
963 does not require white-space before and after the dash in a range, e.g.
964 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
967 Fixed a few AC_TRY_LINK configure tests that did not operate properly
968 due to new GCC removing "redundant" code.
970 Added yaz-client commands scanpos and scanstep that sets preferred
971 position and step-size for scan.
973 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
975 Added CCL utility ccl_qual_buf which parses one or more CCL
976 spec lines in a buffer.
978 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
979 of name and value - ignoring empty lines and comments.
981 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
983 Added odr_get_element_path which returns current element path for an
984 ODR handle. This utility is useful in error handling or user-defined
987 Added ODR_PRINT utility odr_set_stream which is is a more generic
988 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
989 to a write function and pointer to close function. The close function - if
990 non-NULL - will be called during odr_destroy.
992 Fixed bug in CCL parser where truncation char was not removed from
993 right side when truncation=both was in effect.
995 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
998 --- 2.0.23 2004/08/11
1000 Fix buffer overrun in CQL parser when dealing with proximity (%).
1002 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1003 to UTF-8/UCS conversion is now only based on codetables.xml.
1005 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1007 --- 2.0.22 2004/08/06
1009 Add support for more "commit changes" in ZOOM (uses Extended Services).
1011 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1014 Yet another small fix for configure of SSL.
1016 --- 2.0.21 2004/05/14
1018 Fix SSL libs for configure when --with-openssl=DIR is given.
1020 --- 2.0.20 2004/05/10
1022 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1024 SSL comstack now uses yaz.pem certificate file on server side
1025 by default. Certificate filename can be configured by calling
1026 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1028 Fix bug regarding multiple calls to ZOOM_connection_connect.
1030 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1032 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1033 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1035 ZOOM now allows inspection of X509 peer certificate for verification.
1036 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1038 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1039 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1040 as "modular" but it simplifies things.
1042 Added cs_get_peer_certificate to that returns peer X509 PEM.
1044 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1045 NULL if SSL is unavailable.
1047 Documentation about MARC decoding tools.
1049 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1051 --- 2.0.19 2004/03/30
1053 Rename CHANGELOG to NEWS to follow GNU style packing.
1055 Fix bug with missing initialization of member in init_diagnostics.
1056 This bug affects threaded version of GFS server.
1058 --- 2.0.18 2004/03/20
1060 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1063 Ensure zlib.dll is packed with Windows install.
1065 --- 2.0.17 2004/03/17
1067 Fix encoding of xsd:string to use text instead of CDATA.
1069 Fix endless loop in CQL parser with unbalanced ".
1071 Use a more compact way to store MARC-8 conversion tables.
1073 --- 2.0.16 2004/03/16 Debian only
1075 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1078 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1083 --- 2.0.15 2004/03/01
1085 Another fix for decoding of XML packed records.
1087 --- 2.0.14 2004/02/25
1089 Fixes for Chunked encoding. White space not ignored after length spec.
1091 Update NS and use default NS for SRW diagnostic elements.
1093 --- 2.0.13 2004/02/23
1095 Implement ZOOM_resultset_cache_reset which resets record cache.
1097 Implement ZOOM_resultset_sort which sorts a result set.
1099 Implement chunked HTTP transfer.
1101 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1103 --- 2.0.12 2004/02/16
1105 Added member 'schema' to bend_explain_rr structure so that backend
1106 can specify explain record identifier. Defaults to Zeerex 2.0.
1108 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1110 --- 2.0.11 2004/02/16
1112 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1115 Added init command for yaz-client which sends "extra" init request.
1117 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1118 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1120 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1122 Make ZOOM error code for "invalid query".
1124 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1126 --- 2.0.10 2004/02/05
1128 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1131 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1133 Added option -p <file> to make Generic Frontend Server to write PID file.
1135 Added option -D to put Generic Frontend Server in background on its own.
1137 Make ZOOM C recognize option "password". If unset, "pass" is used
1138 (for backwards compatibility).
1140 Fixed a bug in Generic Frontend Server that could make it crash if a
1141 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1144 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1145 Must be issued before open, in order to be in effect.
1147 --- 2.0.9-6 2004/01/12 Debian/Windows
1149 Make the SRU server more picky WRT unknown params, etc.
1151 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1153 New YAZ client command, options, that sets Z39.50 options.
1155 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1156 options from a string of tokens (one token for each option bit).
1158 Update SRW diagnostic code messages.
1160 --- 2.0.9-5 2004/01/07 Debian/Windows
1162 Handle user defined stylesheet for SRW/SRU.
1164 --- 2.0.9-4 2004/01/06 Debian/Windows
1166 Fix bug in decoding of Content-Length.
1168 --- 2.0.9-3 2004/01/06 Debian/Windows
1170 Fix a bug with decoding of XML packed records.
1172 --- 2.0.9-2 2004/01/05 Debian only
1174 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1176 Fix bug in SRW/SRU diagnostics decoding.
1178 --- 2.0.9 2004/01/05
1180 Fixed bug in Generic Frontend Server which could drop records exceeding
1181 preferred message size. Reported and fixed by Irina Dijour.
1183 Fixed calculation of package size for structured records in Generic
1184 Frontend Server. Reported and fixed by Irina Dijour.
1186 Fixed namespace for SRW/SRU diagnostics.
1188 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1190 --- 2.0.8 2003/12/22
1192 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1193 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1196 CQL changes to reflect recent changes to the specification:
1197 * Documentation talks about context sets instead of index sets.
1198 * Documentation talks about indexes instead of qualifiers.
1199 * The CQL-to-PQF transformer's configuration file now uses
1200 "index.set.name = <attributes>" instead of the old form
1201 "qualifier.set.name = <attributes>". (Both forms are still
1202 understood but the latter is deprecated.)
1203 * CQL terms with no explicit index specified are now interpreted as
1204 cql.serverChoice instead of srw.serverChoice (which of course
1205 behaves exactly the same.)
1207 --- 2.0.7 2003/12/16
1209 MARC conversion can now generate ISO2709 output in another
1210 character set. yaz-marcdump uses this facility if you invoke it
1213 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1214 functions from there can be used from C++.
1216 --- 2.0.6 2003/12/04
1218 Frontend server now transfers memory from decoded packages to stream
1221 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1222 references to show up.
1224 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1225 the ZOOM Abstract API. The older names for the same options are still
1226 also supported for the benefit of old applications.
1228 ZOOM-C supports "implementationId" and "implementationVersion" options
1229 to go along with "implementationName". These allow the user code to
1230 specify identification strings to be sent to servers.
1231 Add OID for the new ExtLite attribute set.
1233 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1234 as requested/supplid by Ere Maijala <ere@atp.fi>
1236 For generic frontend server, reverse the order of
1237 "toolkit-supplied / application-supplied" strings sent as implementationId,
1238 Name and Version. Also, remove the spaces around the slash. This brings
1239 the GFS in line with the behaviour of ZOOM-C on the client side.
1241 Add function ZOOM_scanset_display_term.
1243 yaz-client shows scan displayTerm if present.
1245 Utility yaz-iconv is now installed by default along with the man page
1248 Extend configure check for OpenSSL to use pkg-config where available (such
1251 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1252 server to specify uid/gid/mask for socket using the format
1253 unix:[user=uid,][group=gid,][umask=mask,]file=path
1254 If file= is omitted the existing format is assumed, e.g.
1256 in which case the mask is 0666 (rw for everybody).
1258 Major restructure of YAZ source. All source in libyaz is in src directory.
1259 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1260 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1262 Added man page for utility yaz-marcdump (used to be called marcdump).
1263 yaz-marcdump is installed by 'make install'.
1265 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1266 of incoming package failed.
1268 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1270 Change prototype of odr_perror: add const to message string.
1272 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1274 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1275 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1276 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1277 DNS lookup. There should not be any compatibility problems with this
1278 assuming that blocking=1 or 0 is used.
1280 Fix bad reference in UNIX comstack in function cs_addrstr.
1282 Fix for compilation on AIX.
1284 The generic front-end server (server/seshigh.c) now supports returning
1285 Init diagnostics to the client in User-information-field, in
1286 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1289 --- 2.0.4 2003/09/04
1291 Allow any CQL relation (not just all,any,exact,scr).
1293 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1294 that features the same UI.
1296 Implemented command update0 in YAZ client which is equivalent to
1297 update but uses old of Ext Update ASN.1.
1299 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1300 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1301 Previously no OID was used for this info.
1303 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1304 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1305 returns 'malformed search term' otherwise.
1307 SortResponse member resultCount now set to NULL in sort handler of
1310 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1313 Add three new utility functions for translating OIDs between various
1314 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1315 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1316 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1317 char *oid_to_dotstring(const int *oid, char *oidbuf);
1318 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1320 Reverted modifications for ES Update definition for z_IU0Update
1321 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1322 is back to YAZ 2.0.2.
1324 String value attributes for CCL parser.
1326 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1327 which their FirstSearch server returns in Init responses, sometimes
1328 carrying useful diagnostic information when Init fails. This has the
1329 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1330 "z39.50/oclcui.asn", where its definition is somewhat different from
1331 what OCLC document on their web-site, as required to interoperate with
1334 Support for anonymous authentication in yaz-client. Use the command
1337 * Fix the OID of the Index Data-local "admin" Extended Service from
1338 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1339 the 1000, which indicates a locally-defined OID, was a mistake.
1341 --- 2.0.3 2003/06/20
1343 Fix CCL directive @case handling so that it affects string match for
1344 both CCL keywords and qualifiers.
1346 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1347 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1348 Decoder has been updated with ASN.1 changes as listed in
1349 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1350 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1351 z_IUUpdate, remains unchanged.
1353 ZOOM_record_get may now return a record in a specific character set.
1354 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1355 "from" is the character set of record as returned by target. "to" is
1356 the character set to be returned. If omitted, "to" is UTF-8.
1358 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1360 New ODR utility, odr_getelement, which returns name of element for
1361 which encoding/decoding failed.
1363 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1364 in cases where a required element was omitted.
1366 Bug fix: some MARC8 sequences were not converted.
1368 New ZOOM option "step" which specifies number of records to be
1369 retrieved in one chunk. Used in conjunction with "start" and "count".
1371 SRW support for yaz-client. Use scheme http: to use it, e.g.
1374 yaz-client no longer does (un)intelligent character set conversions
1375 by default. Can be enabled with charset and marc_charset commands.
1377 xmalloc trace fix for 64-bit systems such as DEC alpha.
1379 Solaris 2.6 compile fix.
1381 New function, cql_strerror() translates SRW error codes, as returned
1382 by cql_transform_error(), into human-readable English strings. Used
1383 in yaz-client diagnostics when appropriate.
1385 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1386 converts it into a type-1 query which is sent to the server. This
1387 makes CQL available for use with all Z-servers, as opposed to the tiny
1388 minority that can handle CQL queries themselves.
1390 --- 2.0.2 2003/04/28
1392 New Debian package layout similar to the Redhat Package layout.
1394 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1395 and search result respectively.
1397 --- 2.0.1 2003/04/25
1399 Redhat package is now several packages: libyaz (runtime libraries),
1400 libyaz-devel (development and documentation, and yaz (utility programs).
1401 Package spec file by Morten Bøgeskov.
1403 New member 'schema' in struct bend_fetch_rr which the name of requested
1404 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1405 handler MAY set this to reflect the schema of the returned record.
1407 New member 'display_term' in struct scan_entry. GFS now sets member entries
1408 and allocates scan entries to be filled by user scan handler. In previous
1409 version, entries member was allocated by the scan handler. That still works,
1410 but the GFS will ignore member display_term - assuming it was NOT set by
1411 the handler. The fact that the GFS now allocates the entries both allows
1412 for new members and makes a scan handler easier to write.
1414 Fix CQL lex buffer overflow.
1416 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1417 SRU default recordPacking is string.
1419 SRU protocol support for frontend server.
1421 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1423 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1425 Added scan for the ZOOM shell (zoomsh).
1429 * String Identifers for Schemas (Amendment 5).
1430 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1431 Old definition for schema
1432 Odr_oid *schema; /* OPT */
1437 Z_InternationalString *uri;
1438 #define Z_Schema_oid 1
1439 #define Z_Schema_uri 2
1442 * resultCount parameter to Sort Response (Amendment 1).
1443 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1445 Support for SRW 1.0 over HTTP. This is an optional feature and
1446 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1449 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1450 on the same port. SRW SearchRetrieveRequests are mapped
1451 to bend_init,bend_search,bend_fetch,bend_close.
1453 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1455 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1456 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1458 ZOOM connections are SRW based if schem http is used for hostname
1459 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1460 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1462 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1463 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1464 distance=n, order=true/false, relation=le, prox unit=word. If
1465 n is omitted, distance 1 is used.
1467 Fixed problem with C compiler include path in wrong order.
1469 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1470 on Solaris. Patch from Ko van der Sloot.
1472 New MARC decode API. All new functions operate on a yaz_marc_t
1473 handle. The most important new functions are: yaz_marc_create,
1474 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1475 decode and destroy respectively. Decoder can produce formats
1476 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1477 include/yaz/marcdisp.h.
1479 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1480 to UTF-8, UCS-32, wchar_t or Latin-1.
1482 * Prototypes for yaz_iconv_-functions moved to separate header
1483 include/yaz/yaz-iconv.h.
1485 Make a few private functions 'static' in unix.c. This prevents
1486 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1488 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1489 are set when Init Response is received.
1491 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1492 but returns diagnostic set as well.
1494 New function yaz_strerror which is a portable wrapper for
1495 strerror/strerror_r/GetLastMessage.
1497 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1498 is returned for MARC. If type is "oai", then OAI MARC is returned.
1500 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1503 --- 1.9.2 2002/11/26
1505 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1507 Fix bad race conditions on SIGTERM and terminate gracefully in
1510 Move retrieval (data1) module to Zebra since nobody seems to be
1513 Add GRS-1 render for ZOOM using same format as yaz-client.
1515 --- 1.9.1 2002/10/05
1517 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1519 Fix broken ESpec handling in data1 module.
1521 SGML reader parses comments and makes them part of the data1 tree.
1523 Added several type casts so that YAZ compiles as C++ code.
1525 ZOOM didn't handle PDU encoding failures properly.
1527 Added more Bib-1 diagnostics (approved extensions).
1529 GNU configure: better check for iconv.
1531 More portable use of accept, getpeername. Check for socklen_t. Use
1532 int/size_t if socklen_t is not defined.
1536 PQF parser rejects bad queries - including those with extra
1537 characters in them. PQF parser used to silently ignore that.
1538 Cleaner API for PQF added, which allows you to get detailed
1539 error information for bad queries (see yaz/pquery.h).
1541 Fixed bug in ZOOM_record_get for type "database".
1543 Implemented mini iconv library supporting conversions between
1544 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1546 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1548 --- 1.8.9 2002/08/20
1550 Fixed ZOOM C record cache so that preferredRecordSyntax and
1551 elementSetName is used to check for already fetched records.
1553 --- 1.8.8 2002/08/02
1555 Added three members in bend_initrequest structure to facilitate
1556 character set negotiation.
1558 Fixed a bug in frontend server that could cause indefinite
1559 loops under rare conditions.
1561 Revised character set utilities (charneg.h) so that encoding
1562 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1564 For PQF, directive @term <type> sets term type for Scan/Search.
1565 Here <type> is general, string, numeric, null. The term type
1566 is inherited - just like @attr.
1568 New call odr_set_charset that sets character set conversion for
1569 international-strings on a ODR stream. Prototype is:
1570 int odr_set_charset(ODR o, const char *to, const char *from);
1571 The InternationalString is still represented as C string in YAZ
1572 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1573 won't). On the protocol level, you can use any encoding.
1575 Support for UNIX sockets in ZOOM.
1577 Solaris recv sometimes returns errno == ENOENT. It is treated as
1578 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1580 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1581 both client and server. Code by Morten Bøgeskov.
1583 --- 1.8.7 2002/05/22
1585 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1586 that they can be used directly from Visual Basic. You must recompile
1587 your windows APP if you're using ZOOM.
1589 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1590 Commands "lang" and "charset" sets language and character set respectively.
1591 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1592 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1594 Attributes from multiple CCL fields may be OR'ed rather than merged
1595 using directive "@field or". Fields are still merged by default -
1596 equivalent to "@field merge".
1598 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1601 Fixed bug in zget for parameter ExtendedServicesResponse.
1605 --- 1.8.6 2002/03/25
1607 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1609 Client displays USR.1:SearchResult-1 (hits per term).
1611 Additional Search Info for search in Generic Frontend Server.
1613 Fixed CCL parsing of "field=s".
1615 WIN32 installer - using the excellent NSIS software from nullsoft.
1617 Fixed CCL parsing of "field = - <number>".
1619 Added function yaz_marc_decode that decodes MARC for line mode
1620 display or XML (similar to that used by JZKit).
1622 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1623 Z39.50. But ISO/ILL was, however.
1625 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1626 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1628 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1629 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1631 --- 1.8.5 2002/02/03
1633 New YAZ client features: Command completion and new commands:
1634 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1635 Code provided by Jacob Poulsen.
1637 New call oid_trav, that visits all registered OIDs via callback.
1639 Function ZOOM_record_get now returns const char pointer rather than
1640 void pointer. It saves a lot of type casts.
1642 For YAZ client, command "auth" now allows you to set authentication
1643 in IdPass style. It is enabled when three tokens are given - order
1644 is user, group and password.
1646 Fix memory leaks in MARC record handling for ZOOM.
1648 New option for YAZ client, -k <kilobytes> that sets
1649 maximum record size. Similar to -k option for generic frontend
1650 server and yaz-ztest.
1652 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1654 Prefix query parser reports "fail" when bad attribute set is given.
1656 Fix in MARC decoder. Proximity logging. Fix for attribute set
1657 in scan handler for server. Patches by Shigeru Ishida.
1659 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1662 Configure option --with-openssl=<dir> now works when a directory is
1663 specified. Patch provided by Morten Bøgeskov.
1665 New option for YAZ client, -u <auth>, that sets authentication.
1667 ZOOM fix: error information was sometimes "missing", since error
1668 was cleared/reset too when it shouldn't.
1670 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1672 --- 1.8.4 2002/01/04
1674 Scan for ZOOM API. New object ZOOM_scanset. New functions
1675 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1676 ZOOM_scanset_destroy.
1678 New ZOOM function, ZOOM_connection_last_event, that returns type
1679 of last event (such as "receive data", "send data", "apdu received",
1682 New ZOOM option, schema, that specifies schema for retrieval.
1684 New CCL feature. Qualifiers can be aliases for one or more
1685 other qualifiers (if more than one is given, OR is used).
1687 ZOOM uses named result sets if target supports it.
1689 Two new YAZ client commands: . (dot, which sources a script of YAZ
1690 client commands), and ! (to execute shell command.). Implemented
1693 Working on Debian packages.
1695 --- 1.8.3 2001/11/19
1697 YAZ client enables named result sets only if target supports it.
1699 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1701 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1702 with key="host" to get same result.
1704 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1705 Function Z3950_resultset_record(s) returns references to records
1706 "owned" by resultset. To become owner use Z3950_record_clone.
1708 Function z_ext_record handles Extended Services. Thanks to
1711 --- 1.8.2 2001/11/12
1713 CCL Parser fix: ignore token comma when dealing with and-lists.
1715 Documentation updates for COMSTACK.
1717 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1718 Changed prototype Z3950_records. For some functions, int parameters
1719 were changed to size_t.
1721 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1724 New MARC decode/display function, marc_display_exl, which properly rejects
1725 non-ISO2709 records. YAZ client uses it.
1727 --- 1.8.1 2001/10/29
1729 Fix bug: local attribute set wasn't set correctly in PQF strings.
1733 * Old Z39.50 codecs no longer supported.
1735 Added ZOOM C binding. See http://zoom.z3950.org/
1737 Renamed states for COMSTACKs to avoid confusion with events.
1739 Implemented cs_look and proper cs_rcvconnect.
1741 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1743 Configure detects POSIX threads on OpenBSD.
1745 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1746 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1748 When error is returned from present handler, non-surrogate diagnostic
1749 is returned in present response (and fetch handler is no longer called).
1751 * Minor adjustments to pquery parser (PQF). Token characters may be
1752 escaped by using backslash (C-style).
1754 PQF parser allows string attribute values to be specified. For @attr,
1755 non-numeric characters after the equal-sign are treated as strings
1756 (e.g. @attr 9=title).
1758 CCL trunction character may be defined (@truncation in file)
1760 * function zget_ExtendedServicesRequest sets waitAction to
1761 waitIfPossible (was wait).
1763 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1766 CCL operator names may be set in field definition files (CCL_bibset).
1767 See ccl/bib1 for an example.
1769 Fixes in ASN.1 compiler for C++ compatibility.
1771 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1772 and "op_or" to avoid conflict with C++.
1774 Fixed problem with GNU readline detection on Redhat 7.0.
1776 Added step-size for Scan backend handler.
1778 Fixed bug that made the frontend server crash when no attribute
1779 set was specified for scan.
1781 Front-end server automatically switches to original working directory
1782 when installed as an NT service. Previously -w had to be specified to
1785 Added extended attributes for retrieval module (data1), so that data1
1786 records carry d1_readXML/SGML attributes. d1_read also supports
1787 null-data rules ( <tag/>)
1789 On UNIX when POSIX threads are available, a separate library libyazthread
1790 is created. Programmers should link with that library and the yaz library
1791 when using threads. The reason for the split was that some applications
1792 on Linux, such as Apache, doesn't work well when using shared objects that
1795 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1796 (or any frontend server) in SSL mode by specifying ssl: followed by
1797 address. Only tested on UNIX.
1799 Added feature for CCL module. Virtual structure s=al or s=ol generates
1800 and-list and or-list respectively instead of phrase search.
1804 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1805 log_mask_str. This was done to avoid name conflicts with other libraries
1806 (such as other PHP extensions).
1808 Added raw OID member for preferred record syntax (request_format_raw)
1809 and returned record syntax (output_format_raw) for backend fetch method.
1811 Config file yaz-config now accepts options so that it returns specific
1812 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1814 Shared library support for UNIX using GNU libtool.
1816 * Modified backend interface. Request/Response struct's replaced by
1817 one read/write C struct. For example bend_fetchrequest and
1818 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1819 Every handler - even search has to be registered in bend_init
1820 handler. This means that the YAZ library no longer refers to
1821 external functions and it makes it possible to make the whole
1822 thing a single DLL/SO.
1824 Added Segment handler for backend server.
1826 Added Zmbol/Zebra administrative functions to YAZ client.
1828 Threaded frontend server on UNIX (when POSIX Threads are available).
1829 Starting the server with option -T enables multi-threading.
1833 Added configure option --enable-comp/disable-comp to control use
1834 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1835 located in sub directory asn.
1837 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1838 in ${exec_prefix}/bin along with the other programs yaz-client and
1841 GNU automake used to maintain makefiles.
1843 Added several OID's.
1845 Changed retrieval module so that we can load records with no abstract
1846 syntax defined. Tagpaths in these records are fully composed of string
1849 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1853 On UNIX, the generated makefile now supports a proper 'make install'.
1854 The prefix can be set via GNU configure to set the install location
1855 (default is /usr/local).
1857 * YAZ programs client and ztest were renamed to yaz-client and
1858 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1859 locations, such as /usr/bin,/usr/local/bin,etc.
1861 * YAZ Header files were moved from include to include/yaz. YAZ Header
1862 files are referred to as include <yaz/log.h> rather than <log.h>.
1863 The YAZ include path (-I ..) is therefore the same as before. Programmers
1864 should update their #include statements or use -Ipath/include/yaz
1865 instead. The main motivation for doing this change is that YAZ header files
1866 can be installed in "standard" locations /usr/include,/usr/local/include
1867 without introducing conflicts, since ALL YAZ header files are stored
1868 in subdirectory yaz (under /usr/include for example).
1870 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1871 rather than project/workspace files. We switched because project files
1872 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1875 Changed name of logging function, logf, to yaz_log, to prevent name
1876 clash with some math-log functions. The YAZ header log.h defines logf
1877 to yaz_log (#define) so there should be no incompatibilities by this
1880 Added bend_start/bend_stop handlers for server. These handler are
1881 called on start/stop of server. For windows they are called whenever
1882 a service is started/stopped.
1884 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1885 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1886 in util/yc.tcl. The auto-generated C code structures are, in a few
1887 cases, incompatible with the old decoders. There are differences in the
1888 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1889 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1890 The preprocessor variable ASN_COMPILED is defined when the compiled
1891 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1892 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1893 wish to use the old encoders/decoders you can specify --disable-yc
1896 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1897 version so that it supports both new - and old version of DB Update
1899 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1900 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1901 change. The name parameter can be set to 0 in which no name is specified
1902 for the construction. The macros odr_implicit and odr_explicit sets name
1903 parameter to zero for the construction involved. New macros
1904 odr_implicit_tag and odr_explicit_tag are similar to the others,
1905 except that a name parameter is added. For programmers' that don't use
1906 ODR they probably only need to change the call to z_APDU and z_External.
1908 Added access control facility by interfacing the TCP wrapper library.
1909 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1910 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1911 name of the daemon and enables the access control as specified in
1912 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1914 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1915 den Dool <H.M.vdnDool@kub.nl>.
1917 Added reference ID parameter to most functions in server API - refer
1918 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1920 Changed name of ccl library to libccl.a (was ccl.a).
1922 Fixed bug in decoder for Explain (Category TargetInfo).
1924 Added support for GNU readline in client. Thanks to Jacob Poulsen
1925 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1927 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1928 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1929 IMPLEMENTATION! This change was made to the development version before
1930 the ZIG decided to retract the amendment. If any users MUST be
1931 compatible with the original Update definition, PLEASE CONTACT US, and
1932 we will include a separate definition corresponding to the old Update
1933 ES. Note that because of the change to the ASN.1 of the
1934 TaskPackageRecordStructure we cannot define a single structure that
1935 will support both versions.
1937 * Added const modifier to buffer parameter for some ODR/BER encoding
1938 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1939 completeWAIS, odr_dumpBER.
1941 Fixed bug in client.c which caused a crash when a scanResponse didn't
1942 contain positionOfTerm.
1944 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1945 * will cause an error in a client if a non-YAZ target sends both a
1946 * list of Scan entries and non-surrogate diagnostics.
1948 Retrieval module enhancements. Tag sets may be typed in the reference
1949 to it. From the .abs-file the "tagset" directive takes a third optional
1950 integer type for the tag set referenced. From a .tag-file the "include"
1951 directive takes a third optional type as well. The old "type" directive
1952 in the tag set itself is still recognized but acts as the default type
1955 Backend interface change. Individual Scan terms returned from bend_scan
1956 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1957 in include/backend.h.
1959 Retrieval module enhancements. Multiple tag sets and attribute sets may
1960 be specified in abstract syntax specs. Revised the error/warning for
1961 logging messages reported by the retrieval module when reading the
1964 Object Identifier system (oid_..) changed. The API is backwards
1965 compatible but the oid-routines now allocates new OID's when needed.
1966 Raw OID's may be specified in oid_getvalbyname.
1968 YAZ now uses GNU configure to generate Makefile(s).
1970 * Minor changes in some of the member names of DeleteResultSetRequest and
1971 DeleteResultSetResponse. See include/proto.h.
1973 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1974 and added member 'languages' in TargetInfo (which was missing).
1976 Changed the way attribute sets are handled in the retrieval
1977 module. These are now cached, just like the abstract syntaxes
1980 Changed YAZ so that it links with compiled ASN.1.
1982 Added Explain-schema definitions and mapping routines. The following
1983 Explain categories have been implemented: AttributeDetails,
1984 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1986 Fixed minor bug in Windows version of Server Library.
1988 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1990 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1992 Added EXTERNAL: UNIverse Resource Report (non-standard).
1994 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1995 ENUMERATED and SET OF.
1997 * Added 'const' to some of the char pointer arguments for the
1998 functions, data1_read_node, data1_getelementbytagname,
1999 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2002 Fixed bug in data1_insert_taggeddata - the last_child member of
2003 parent wasn't initialised.
2005 * Changed data1_read_record and data1_read_node so that the supplied
2006 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2007 doesn't refer to any parts of the "SGML"-buffer.
2009 Fixed bug in server library (Windows version of statserv_remove).
2011 * Changed code so that it compiles as C++. The type definition
2012 of Odr_fun which is a member of Odr_arm was changed. The result is,
2013 that an explicit typecast is needed for the fun pointer when
2014 using Odr_arm - as in:
2015 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2017 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2019 Implemented the new structured date and time definition as approved
2020 by the ZIG. Added schemaId element to the specificTag in Espec-1
2021 (also approved at the last ZIG). Thanks to RVDM.
2023 Added some Object identifiers (RVDM).
2025 Changed the Update Extended Service (RVDM).
2027 Added command "refid" to client which specifies referenceId for
2028 the following requests.
2030 Implemented extended service handling for server. See ztest.c
2031 for an example as well as backend.h. New handlers are registerd
2032 in the Init handler.
2034 * Changed interface for sort in server.
2036 Added new members to statserv_options_block. It allows a server
2037 to read options from another source than just the command line. Thanks
2038 to Charles Woodfield.
2040 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2041 renamed to zboolean. Some C++ compilers complained about the name.
2043 Minor changes to gils.abs. Added index 's' (sort) on title
2044 and date/time-last-modified.
2046 --- 1.4pl2 1998/1/30
2048 Fixed bug in server library regarding inetd mode (-i). This bug
2049 was introduced by release 1.4.
2051 --- 1.4pl1 1998/1/29
2053 Added sort facility in client and backend server interface.
2055 Fixed problem with dependencies in Makefile(s).
2057 Fixed bugs for encoders/decoders of extended services and
2060 Implemented sub-tree feature for schemas. Sub-trees are
2061 referenced in *.abs-files. See explain.abs for an example
2062 of the use of this feature.
2064 Modified bib1.att; local attributes for ANY didn't include
2065 ANY itself (only affects use of the retrieval module).
2067 Fixed bug in plain SGML reader in function data1_read_node:
2068 tags with prefix "var" was incorrectly interpreted as variants.
2070 Added feature "sub-schemas" to enable references to - and definitions
2071 of - group of elements.
2073 * Removed member parent from type data1_element (in data1.h).
2075 Implemented function odr_nullval() that returns the value of
2078 * Removed member num_children from data1_node (in data1.h).
2080 Made NT service interface part of the server library. The
2081 function statserv_main uses the NT service when required and
2082 calls the statserv_start / statserv_close routines.
2084 Routine zget_SearchRequest and zget_PresentRequest fills
2085 resultSetName/Id member with "default" instead of "Default".
2087 Fixed memory leak in server. Request queue member wasn't freed.
2089 Fixed nmem_exit so that memory is freed.
2093 Revised the CCL parser utility to be thread safe.
2095 Added function, oid_ent_to_oid, to replace the function
2096 oid_getoidbyent, which is not thread safe.
2098 * Added nmem_init and nmem_exit to initialize and release
2099 NMEM resources. Function nmem_init should be called once in the
2100 initial thread before NMEM/ODR is used. statserv.c and client.c
2101 have been changed accordingly. The change was necessary to make
2102 NMEM thread safe. The NMEM memory pool is shared amongst threads
2103 in a process. Unix-based applications will still work fine without
2106 Added NT Services interface for the the Z39.50 (statserv) Server.
2107 Refer to the ztest.c source on the usage.
2109 Windows 95/NT port using MSVC5.0. Project files are included in the
2112 * Defined new 'global' handle for the retrieval (data1) system. The
2113 new handled, data1_handle, describes the state of the data1 system.
2114 This handle is passed as first argument to virtually all
2115 data1 related routines. The functions data1_create and data1_destroy
2116 creates and destroys a data1 handle respectively.
2118 Added ODR encode stream member to all backend request structures
2119 init, search, scan etc. This stream should be used to allocate all
2120 memory used for the response when thread safe operation is needed.
2122 Changed the comstack utility, cs_addstr, to be thread safe. The
2123 returned hostname string returned by the function is now part the
2126 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2127 function. The cs_straddr takes a COMSTACK handle as argument, so this
2128 function must be used after cs_create and before bind/connect.
2129 This function is thread safe.
2131 Moved test server to 'ztest' directory - generic server code still
2132 in 'server' directory.
2134 Made prefix query (pquery.c) utility thread safe.
2136 Added new function modifier YAZ_EXPORT to 'export' public DLL
2137 functions when using windows (see include/yconfig.h).
2139 Added definitions to the OID database (util/oid.c) (RVDM).
2141 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2143 Added call to ccl_rpn_delete in client program.
2145 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2146 release of RPN structure.
2148 Added support for C++, headers uses extern "C" for public definitions.
2149 With input from RVDM.
2151 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2152 Thanks to Ronald van der Meer (RVDM).
2154 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2156 Added support for private extensions to the OID database
2157 (oid_setprivateoids()). Thanks to RVDM.
2159 Added optional, physical ANY (key replication)
2161 Fixed null-reference problem in GRS-1 output filter.
2163 Proximity operator added to Prefix Query Format (PQF).
2165 In test client command "base" accepts multiple databases.
2167 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2171 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2173 Smallish bug-fixes in the new encoders/decoders (explain).
2175 Bug fixed in DeleteRequest.
2177 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2179 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2181 Added SOIF syntax (using private OID for now) to retrieval module and client.
2183 Added Update extended service.
2185 Added SearchResult-1 additional info structure.
2187 Added optional CCL (ISO8777) interpreter as separate module. Available
2190 --- 1.2 1996/6/10 (1st anniversary release)
2192 Added Summary record syntax. Lightly tested.
2194 Added OPAC record syntax. Untested.
2196 Added ResourceReport service encoders/decoders. Untested.
2198 Fixed bug in z_Unit - wrong tagging on unitSystem.
2200 Fixed bug in the DiagRecs decoder.
2202 Added options for max PDU size and session timeout to frontend-server.
2204 Added documentation of query-language parsers and other supporting utilities.
2206 [frontend-server] Added Attribute set to the bend_scanrequest API.
2208 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2209 surrogate diagnostics were generated.
2211 [retrieval] Allow multiple local values for attribute.
2213 [retrieval] Allow multiple attributes per element in .abs files. index type.
2215 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2217 --- 1.1pl2 1996/4/10
2219 Minor changes, mostly specific to Zebra's requirements (retrieval)
2223 Repaired bug in frontend server when running multiple listening
2224 endpoints in dynamic mode.
2226 z_External() now won't break if a known, ASN.1 value comes encapsulated
2227 in an octet-string. The value will pass through unmodified in an Odr_oct.
2229 Added a bit of code to the demo client to decode & display
2230 ASN.1-structured records represented in the octet-aligned branch of
2231 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2233 Added z_ext_getentbyref() to the ASN module. Doc updated.
2235 * Completed the SCAN definition in the ASN module. This may break SCAN
2236 code based on older YAZ-versions at compile-time. The fix is easy -
2239 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2240 under the SCAN definition. Remember to initialize this, server-people.
2242 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2243 that this does not extend to ODR and ASN.
2245 Comstack allows insertion of established socket (primarily for
2246 inetd-operation of servers). Doc updated.
2248 Front-end server can now start from the inetd in TCP mode. Doc
2251 --- 1.0pl4 1996/1/24
2255 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2256 the rank and record number.
2258 Adjustments to the frontend server.
2260 Fixed diagnostic BER dumper. It ignored the file argument.
2264 Various changes to retrieval module.
2266 Changed the union discriminators of the protocol files from enums to
2267 ints paired with #defines.
2269 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2272 *Changed operator in the RPN structure to 'roperator', again to avoid a
2275 Fixed problems in Explain decoders/encoders.
2277 --- 1.0pl2 1995/12/6
2279 Memory bug in log module fixed.
2281 --- 1.0pl1 1995/12/5
2283 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2285 Bug in Explain DatabaseInfo module fixed.
2287 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2291 The shift to v1.0 signals that we now consider the *core* functionality
2292 of YAZ reasonably stable (the core being more or less equivalent to
2293 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2294 tested (Explain not at all - though that will happen soonish).
2296 Minor changes to code to support Windows port.
2298 Various minor changes after we're getting to use GRS-1 & co. more.
2300 Added Espec-1 format.
2302 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2303 of the protocol and it cannot be selected when encoding (maps into 'string'
2304 when decoding). Needed to talk to some servers.
2306 Demo client can request simple element set names.
2308 Added Diagnostic Format encoders/decoders.
2310 Added simple Close handling to frontend server (no hooks for resource
2311 reporting yet), and demonstration client.
2313 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2315 --- 1.0b3 1995/08/24
2317 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2318 handled incorrectly when records were requested in the searchResponse. This
2319 will only affect you if you use the frontend-server.
2321 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2322 Test-client will ask for and print GRS1. Ztest will return dummy records
2325 Added Explain encoders/decoders to the service-level API. Untested.
2327 Added Extended Services: Item Order encoders and decoders to the Service-
2328 level API. Untested. We could use a recent copy of the pertinent bits
2329 of the ILL protocol to add those bits.
2331 Added diagnostic format 1 encoders/decoders to the service-level API.
2334 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2335 odr_cons.c, which causes a more correct output.
2337 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2338 was always set to 0 when no records were requested in the searchRequest.
2340 * Added better external-handling. This shouldn't harm old code that
2341 *encodes* externals. It can break code that looks for a
2342 'single-ASN1-type' representation, since those types that are known
2343 are now decoded immediately. Look at the SUTRS sample code in
2344 seshigh.c and client.c. Documentation updated.
2346 Handling of structured records in bend_fetchresponse. Length -1 marks
2347 structured record, type is deduced from format field.
2349 --- 1.0b2 1995/06/27
2350 Fairly quick maintenance release to add SUTRS support.
2352 Fixed handling of SUTRS records in the demonstration client.
2354 * Added format field to the bend_fetchrequest and bend_fetchresponce
2355 structures of the backend API (frontend server). When the record is
2356 returned, the value of the format field is mapped to an OID. The
2357 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2358 of the record. The special value VAL_NONE in the bend_request means
2359 that no specific format was requested by the client. Documentation
2360 updated accordingly. Test server (ztest) will return a fixed dummy
2361 SUTRS record if your client requests SUTRS.
2363 Documentation updated accordingly.
2365 You can now set external libraries and RANLIB support in the top-level
2369 First public release.
