3 Fixed version in yaz/yaz-version.h.
7 Fixed bug #2027: Crash when closing connection.
9 Changed configure so that ICU support is only enabled if only ICU
10 and Libxml2 is available (because the ICU chain is XML based).
14 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
15 is built. Only this DLL depends on the ICU runtime.
17 yaz-ziffy is no longer part of YAZ. It is distributed separately by
18 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
20 Changed license of CCL module to 'Revised BSD'. After consultation with
21 remaining members of the original EUROPAGATE consortium, we are re-issuing
22 the CCL module without a separate license. The software was developed by
23 Index Data as part of a research project. The special license was included
24 to help feed usage information back to the project consortium to support
25 project evaluation. At this time, the project consortium has long-since
26 disbanded, and the majority of the original principals have retired. At the
27 same time, we have significantly modified the software during the following
28 years, to the point where very practically no original code remains. To
29 simplify re-use of the software, we have contacted those members of the
30 consortium who could be reached, and agreed to re-issue the module as a
31 proper part of the YAZ package.
33 Tcl scripts uses /usr/bin/tclsh as preferred shell.
35 CQL closer to being version 1.2 compliant. CQL also allows free-form
36 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
39 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
40 bug could make Extended services handling crash in the ZOOM layer. This
41 bug was only present in YAZ 3.0.18.
45 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
48 yaz-marcdump reads and writes collection wrapped records.
50 Handle OPAC for record conversion module.
52 Fixes for ICU wrapper.
54 Allow ICU libs to be controlled with --with-icu .
58 Added yaz_poll which is a wrapper for select/poll. When poll is available
59 and non-buggy, it is used, by yaz_poll . This allows more than 1024
62 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
63 functionality through an XML based configuration (ICU chain). This system
64 is useful for search facilities such as Pazpar2 and Zebra that needs to
65 perform tokenization of indexed material. The ICU code in a separate
66 library libyaz3_icu.a.
68 Added HTTP tunnel facility for COMSTACK, bug #1752.
69 This is a facility that allows a Web proxy, such as squid, to tunnel
70 Z39.50 traffic. This facility is "transparent" to must applications
71 using YAZ. It's enabled by using pseudo transport connect: followed by
72 the proxy address, followed by command, then follwed by he regular
73 "virtual" addresss. For example,
74 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
76 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
80 Fixed bad memory reference in ZOOM_record - cuased by member not being
81 initialized. This was a problem only in YAZ 3.0.12.
83 Fixed bug in conversion from MARC to XML: Non-XML characters in control
84 fields were not removed.
86 Changed the way C code is generated from codetables.xml. Made a MARC-8
87 conversion trie for each characterSet section rather than codeTable.
88 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
89 of codetables.xml from Larry Dixson, LOC. Bug #1464.
93 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
94 from ZOOM_record_error).
96 ZOOM C function ZOOM_record_get returns record schema for type="schema".
98 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
100 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
102 Better SRW-to-Bib-1 diagnostic mapping.
104 ZOOM C and yaz-client announces SRU version 1.2 by default.
106 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
109 Fixed in yaz_sru_decode to allow other version than 1.1.
111 --- 3.0.10 2007/08/22
113 Added support for SRU scan for ZOOM.
115 Added support for the use of the older versions or Extended Service
116 Update in ZOOM. To faciliate this, an option "updateVersion" may be
117 set to the version , 1=first, 2=second, 3=third. The third version is
118 what ZOOM C has used so far. And that, obviously, is the default.
120 Added support for CCL queries in Z39.50 queries sent to the GFS (and
121 therefore in Zebra and in SimpleServer-based applications). The new
122 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
123 qualifier file used to transform incoming CCL queries into Type-1 RPN,
124 which is passed into the back-end search callback function.
126 Added support for HTTP Basic authentication in clients: the SRU/W
127 codec encodes the username/password elements of the PDU structure
128 appropriately, and these may be set using the "user" and "password"
129 options in ZOOM-C applications (the same options that are used for
130 Z39.50 authentication).
134 Fixed bug #1208: SSL appears to be broken in ZOOM.
136 Fixed bug #1206: Libxml2 include path weirdness.
138 Added oid_name_to_dotstring.
140 Allow elementSetName to be specified for ZOOM C record update.
142 Allow waitAction to be specified for ZOOM C based for Extended Services.
144 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
145 syntax OID. Bug introduced in YAZ 3 series.
147 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
151 Fixed bug #1157: yaz-client does not read .yazclientrc from current
152 directory. yaz-client now reads commands from file given by option -f
153 if specified; then tries to read .yazclientrc in current directory.
154 Failing that, it reads .yazclientrc from user's home directory.
156 Added support for correlationInfo Note and ID for Record Update via
159 Added yaz-client command querycharset which specifies character set for
160 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
161 (termListAndStartPoint).
163 Charset ISO5428:1984 is an alias for ISO5428-1984.
165 Implemented a way to perform scan in a result set using Z39.50. This
166 is achieved by attaching the result set name in the characterInfo
167 (type InternationalString) of OtherInformation in the Scan Request PDU.
168 The result set is identified in the otherinformation by the new OID:
169 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
170 This allows for scan in result set and faceted search . Zebra did some
171 of this in the APT term using attribute type 8 and value being result
172 set. Using the OtherInformation approach for this is cleaner and easier
173 to work with in proxies and the like. This facility can be used in
174 yaz-client using new command setscan which takes a result set as first
175 argument, start position (APT) as second.
177 Changed decoding of SRU XML packed records to deal with servers that
178 have recordData with XML data with multiple root nodes. Also make
179 comparison for recordPacking case insensitive. Again, one server
180 returns "XML" where others return "xml".
182 For SRU responses allow Content-Type application/xml as well as text/xml.
186 Fixed bug in character set conversion of BER strings. Bug introduced
191 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
193 For OID class, use oid_class consistently.
195 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
198 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
199 character set for bibliographic information interchange". By Giannis Kosmas.
201 Added documentation on new OID API.
205 Changes to generic frontend server interface: added new member
206 'query_charset' for bend_initrequest structure. A backend init handler
207 should set this member to its native character set for query terms.
208 When defined, the frontend server logic will announce this character set
209 to a client if the negotiationModel bit is set by the client. All server
210 implementors are encouraged to specify this. If a backend server does not
211 specify this a warning is issued using yaz_log(YLOG_WARN,..).
213 Added CCL utility to remove terms (stop words) from resulting RPN
214 tree. This is handled by functions with prefix ccl_stop_words_ .
216 New ZOOM C option, "rpnCharset", which allows client-side conversion of
217 terms in RPN queries.
219 Clean-up the CCL API. Moved some internal structures from ccl.h to
220 private header cclp.h. Changed ccl_parser_create so that a Bibset must
221 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
222 This is replaced by ccl_parser_find_str which takes a string instead.
224 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
225 libyaz.la is the core of YAZ except the generic frontend server and
226 does not depend on POSIX threads anymore. libyaz_server.la is the
227 generic frontend server facilities and uses POSIX thread functionality
228 if available. The libyaz.la no longer depends on POSIX threads because
229 the number of global structures is limited. NMEM no longer re-uses blocks
230 between threads ; it simply free's memory immediately but allocates in
231 "large" chunks as usual. We don't expect any performance penalties
232 because of this. The yaz_log system is still using a global log_level so
233 caution must be taken when modifying it with yaz_log_init_.. +
234 yaz_log_mask_str. This, however, should not cause any trouble because
235 these functions are called during initialization of application code
236 anyway. `yaz-config --libs server` returns libs for server applications;
237 `yaz-config --libs` returns libs for non-server applications.
239 New OID database - with public definitions in oid_db.h. Removed old OID
240 database including the head oid.h and definitions such as enum oid_value
241 and struct oident. The new OID database uses the same string names as
242 before but the 'protocol' is gone. There are now only two representations
243 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
244 converts from string to OID; functions with prefix yaz_oid_to_string
245 converts the other way.
247 Change to emit_term() in CQL-to-PQF query translation: when a term has
248 the /regexp relation modifier, do not process it for leading and
249 trailing "^" and "*", which have quite different meanings in regular
252 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
253 write handlers no longer carries a 'last' parameter. This will make
254 yaz_iconv flush "less" characters. A flush is performed by call to
255 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
257 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
258 removed, because function yaz_query_to_wrbuf does the same.
260 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
261 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
263 Deprecated MARC utility functions removed.
265 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
268 Branch split: YAZ_2_1_55_branch
270 --- 2.1.54 2007/03/16
272 Fix to ZOOM-C so that transparent reconnection is properly handled on
273 connections that are in asynchronous mode.
275 Fixed compilation on OpenBSD 4.0.
277 Large strings in GRS-1 records are now properly displayed in yaz-client.
279 Added character conversion support for "advancegreek"; based on patch from
282 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
283 sequence is met. Before the error was not set so it would be unknown.
285 Adjust yaz-marcdump MARC reader so that it skips until record separator
288 --- 2.1.52 2007/03/07
290 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
291 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
292 fd_set structure used as a bitmask for the FDs to be selected on.
294 Using ACX_PTHREAD macro to check for POSIX threads.
296 Fixed have-vsnprintf check.
298 --- 2.1.50 2007/02/23
300 Fixes for configure on BSD. Bug #900.
302 Added snprintf/vsnprintf wrappers for systems that don't have
303 limits (heavens forbid).
305 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
306 created before all previous tasks were completed and removed from the
307 task queue, the new task could be removed by a mistake.
309 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
311 Implemented pass-through CQL-to-PQF conversions. Bug #861.
313 Fixed bug #832: Problem with MARC/charset in yaz-client.
315 Fixed bug #668: save command line history for yaz-client.
317 Fixed bug #830: pkg-config support.
319 --- 2.1.48 2007/01/23
321 Extended ZOOM result set options with two options that may be read by
322 a client: resultSetStatus and presentStatus with values as specified for
324 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
326 Fixed bug #827: Using SSL fails on Debian etch.
328 Fixed bug #826: Weird looking chars for set of MARC records.
330 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
331 that is treated as an ItemOrder with itemRequest being an XML document
332 external. The value of "doc" is the content.
334 Extended the GFS search facility. New member of bend_search_rr
335 'estimated_hit_count' signals that hits is known to be an estmate
336 (higher or lower than real hit count). New member 'partial_resultset'
337 signals that the search was partial (hit count is lower or equal than
338 real hit count). For Z39.50, the information is stored in resultSetStatus
339 member of SearchResponse APDU. For SRU, the information is signalled
340 via SRU diagnostic 59: "Result set created with valid partial results
343 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
345 --- 2.1.46 2007/01/13
347 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
349 Added ZOOM_connection_peek_event.
351 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
352 the following new functions:
353 ZOOM_event_nonblock, ZOOM_connection_process,
354 ZOOM_connection_get_{socket,mask,timeout},
355 ZOOM_connection_fire_event_{timeout,socket}.
356 The existing blocking event handler, ZOOM_event, is a wrapper for the
357 + blocking ZOOM_event_sys_{poll,select}.
359 Implemented function ccl_xml_config which parses XML version of CCL
360 configuration (bug #798).
362 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
364 Added timings utility (yaz/timing.h)
366 --- 2.1.44 2007/01/03
368 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
371 Fixed bug #779: Rotation of apdu.log fails.
373 Fixed for character set conversions:
374 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
375 Honor G1 set in MARC-8 decoding.
377 --- 2.1.42 2006/12/17
379 Fixed bug #775: char conversion does not handle Alternative UTF-8
382 Implemented function yaz_marc_read_line which parses MARC line format
383 records. There is a wealth of formats out there. So far, this function
384 reads line records produced by yaz_marc_write_line.
386 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
387 more generic and easier to remember(!) options: -i format and -o format
388 which specifies input format and output format respectively - where
389 format is one of "marc", "marcxml", "line", "marcxchange".
391 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
392 does not print anything except warnings for records.
394 For yaz-marcdump, added support for MARC split into files (-s) with a given
397 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
398 spec, at http://www.loc.gov/standards/sru/record-update/
399 This has changed the binary layout of the following structs:
400 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
401 bend_update_rr . Patch by Ko van der Sloot.
403 Added GFS utility function bend_assoc_is_alive which returns 1 if
404 association is still alive (client is connected); 0 otherwise (client
405 closed connection). This allows busy servers to stop working for
408 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
409 been a separate piece of software. This version of ziffy has been modified
410 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
412 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
414 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
415 Client code may now interrogate options such as "init_opt_sort" to
416 find out whether the server claims to support various options.
418 --- 2.1.40 2006/11/27
420 Added utilities yaz_{set,get}_esn to set/get element set name from
423 Removed the build of libyazthread.la. The libyaz.so is the threaded version
424 of YAZ and has been so since YAZ 2.1.10.
426 Implemented ZOOM_record_error which returns error information for
427 record (surrogate diagnostic).
429 --- 2.1.38 2006/10/31
431 Updates for SRU Update by Ko van der Sloot:
432 1. Changed name from "operation" to "action"
433 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
434 versions in the code, marked as 'backward compatible'.
435 3. Added diagnostics for SRU Update.
437 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
439 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
441 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
443 For GFS, fixed problem with SRU diagnostic 'First record position out of
444 range' being issued for 0 hits.
446 zoomtst10 part of Windows Build.
448 --- 2.1.36 2006/10/13
450 Implemented yaz_filepath_comp which splits a path into file path
451 components (required by Zebra 2.0.3+).
453 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
454 BSD inspired license until now so this should not have any real impact on
455 anybody. See http://www.opensource.org/licenses/bsd-license.php
457 Fixed bug #687: Missing log lines.
459 Fixed bug #678: CQL to PQF translation does not preserve double-quote
462 Fixed bug #689: SRU diagnostics to be added.
464 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
465 whether a connection is idle (no more work do do).
467 --- 2.1.34 2006/10/04
469 Change type of optval from long to int for invocation of setsockopt with
470 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
472 Added support for specifying the max log file size for the Generic
473 Frontend Server. The size is given with option -r.
475 --- 2.1.32 2006/09/21
477 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
479 --- 2.1.30 2006/09/17
481 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
484 Fixed bug in Generic Frontend Server that could cause a server to stop
485 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
487 For the generic frontend server, the maximum record size is used as maximum
488 size of incoming packages (SRU + Z39.50). The value until was previously
489 only used in Z39.50 Init negotiation and, later, in a session controlled
490 sizes of records returned. This is controlled using -k option. It can be
491 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
493 --- 2.1.28 2006/09/04
495 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
498 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
500 New option for yaz-marcdump -lpos=value which allows setting a portion
501 of MARC header to a certain value.
503 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
505 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
506 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
508 --- 2.1.26 2006/08/15
510 Fixed problem with SRU mode type (soap, get, post) for yaz-client
513 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
515 --- 2.1.24 2006/08/08
517 Fixed MARC ISO2709 encoding routines to deal with character set
520 Minor changes to GFS logging. Database included in search request log
523 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
524 cached/multiple records.
526 Shared libraries are built by default on Unix+configure.
528 Changed cql2pqf transformation to use a different evaluation order. The
529 new order is: always, relation, structure, position, truncation, index
530 and relationModifier. Old order was: always, relation, relationModifier,
531 structure, index, position, truncation. Note that the the latter ones
532 override former ones for identical attributes.. The new scheme means that
533 it is possible to override any existing attribute with a relationModifier.
534 And also that it is possible to override everything for the index rule
535 (except the ones listed in relationModifier). No order is perfect but this
536 one, we believe, covers more real cases.. The "always" should have been
537 called "default", since the attributes there can be overridden with all
540 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
541 compilation phase, but also for yaz-config --cflags output. This allows
542 us to have public headers with Libxml2 stuff in them . It should also,
543 eventually, make Libxml2 checks redundant in packages using YAZ, such
546 --- 2.1.22 2006/06/15
548 Changed SRU update structure bend_update_rr so that SRU diagnostics are
549 stored in uri, message and details.. Previously diagnostics were stored
550 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
551 compatibility.. but he's probably the only one affected, so.
553 Added support for CCL, compiled on the client side, in ZOOM-C. This
554 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
555 input; the resulting query objects can be used for for searching with
556 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
558 YAZ' configure searches for OpenSSL by default.
560 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
561 SL_CTX_use_certificate_file. See
562 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
563 for more info. Thanks to Ko van der Sloot.
565 --- 2.1.20 2006/06/02
567 Bug #600: SRU GET, POST support for yaz-client. Introduced
568 command 'sru' which selects method SOAP/GET/POST.
570 Allow missingValueAction to be specified for the sortspec string -
571 function yaz_sort_spec. By default, the missing value action is null.
572 Use ! to specify "abort". Use = followed by stringvalue to specify default
575 Ensured that Present-handler (if defined) is called in GFS before any call to
576 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
577 searchRetrieve requests.
579 Documentation for YAZ is now based on the Docbook XML/XSLT using
580 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
581 is no longer depending on jade/openjade or docbook-to-man scripts.
582 PDF is no longer part of the distribution - but can optionally be
583 made using DSSSL/jadetex or FOP.
585 Added retrieval handling support in Generic Frontend Server to support
586 conversion between MARC/XML as well as XSLTtransforms. See
587 etc/yazgfs.xml for an example.
589 Added Authentication support to Generic Frontend Server in SRU
590 mode. Authentication using HTTP Basic is supported, as is the use
591 of 'x-username' and 'x-password' parameters in the request itself.
593 Added support for a new character set MARC8s identical to MARC8 except
594 that it converts combined characters to single Unicode characters in the
595 Latin-1 range (when possible).
597 --- 2.1.18 2006/04/24
599 ASN.1 compiler 0.4: generates brief Doxygen file header for
600 generated .h/.c files.
602 Utility yaz_iconv now supports conversion to MARC-8.
604 New facilities for the MARC module. The reading - and writing of
605 content are separate methods for the yaz_marc_t handle. The following
606 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
607 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
608 format). Write functions have prefix yaz_marc_write_.. The existing
609 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
610 available. Removed support for OAI-MARC and simplexml (not the
611 simplexml from PHP5).
613 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
614 to be returned for this connection.
616 --- 2.1.16 2006/03/31
618 Allow multiple languages and charsets to be specified with
619 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
620 negcharset iso-8859-1,utf-8
622 Translation of proximity nodes from CQL into PQF now works.
624 Moved to automake 1.8, 1.9.
626 Added function yaz_log_set_handler which allows a log handler to be
627 installed. This handler will be called for all log messages. Output
628 to file is also produced; but that can be disabled by passing NULL
629 fname to yaz_log_init_file.
631 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
633 For SRW (including GFS), accept application/soap+xml as content-type
636 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
637 produces NO stylesheet reference even if a default stylesheet is specified
640 --- 2.1.14 2006/03/14
642 Updated Windows package to include yazd.dll + yazd.lib for the
643 Development component.
645 If the environment variable YAZ_LOG is set, then it is used as a
646 string indicating the default level of logging to use if not
647 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
648 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
649 used as before. So, for example, to omit warnings from YAZ logging,
652 cql_transform() now map structure and other attributes before indexes,
653 so that index-specific structures and other attributes can override
654 defaults. So now a combination of mapping specifications such as:
656 index.dc.date = 1=date-modified 4=5
657 does the right thing.
659 cql_transform() now also respects the "always" mapping specification,
660 which establishes an initial set of attributes to be used for all
661 terms except where overridden by more specific attributes associated
662 with the index, relation or modifier.
664 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
665 which mode to use; one of "post", "get" or "soap" (SRW, default).
667 Fixes for yaz_iconv routines: changed trie-based character set conversions
668 to use only non-negative values for bit fields due to Sun's C compiler not
669 supporting negative values.
671 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
672 sequences where not read correctly. Fix by Rustam Usmanov.
674 Updated win/makefile to use options, settings which makes things
675 compile with VS C 2005.
677 --- 2.1.12 2006/02/01
679 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
681 In ZOOM socket code, use select instead of poll on MacOSX.
683 ZOOM-C now support client-side compilation of CQL into RPN that is
684 sent to the server, enabling CQL to be used against all Z39.50
685 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
686 ZOOM_query object, and submit it using ZOOM_connection_search().
687 The CQL-to-RPN translation uses a configuration file, the name of
688 which must be specified in the Connection's "cqlfile" option.
690 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
691 function, which takes as its start-term parameter a ZOOM_query object
692 (which may have had either CQL or RPN set into it).
695 --- 2.1.10 2005/11/29
697 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
698 GFS to support this as well. Backend handler, bend_srw_update, does the
699 update work. Code contributed by Ko van der Sloot.
701 Allow retrieval of Search Result-1 information in ZOOM by the use of
702 options that are attached to a result set. ZOOM documentation updated
705 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
706 UTF-8 conversion. Patch by Raj Patel.
708 Added option -m to GFS to control formatting of timestamps in log file.
710 Added 'exit' as synonym for 'quit' in yaz-client
712 Added support for specifying SRW resultSetId + resultSetIdleTime in a
713 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
714 for the new members. Patch by Ko van der Sloot.
716 Added support for SRU POST. It is supported for content-type
717 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
719 Do not build the separate Multi-threaded (MT) library libyazthread.la.
720 Instead make the library libyaz.la multi-threaded. Threading as a whole
721 can still be disabled by configure option --disable-threads. Previosly,
722 with older GLIBCs there were problems with MT libs under Apache. This
723 has now been fixed a long time ago.
725 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
728 CQL module modified to be case insensitive for relations/indexes/operations.
730 Fixed bug in CQL transform code: incorrect value relationModifieder
733 Added 'show all' command for yaz-client which retrieves all results
736 Added new yaz-client, xmles, which takes a (private) OID and
737 a document to be sent as an extended service request.
739 Describe new yaz-client commands wait_response and set_auto_wait.
741 Increase TCP/IP listener backlog from 3 (which I am guessing was
742 copied from the SunOS manual entry way back when) so SOMAXCONN, so
743 that the socket will queue as many incoming connections as it's able
744 to handle ongoing connections. In other words, it will never now
745 refuse a connection that it would be able to handle merely because
746 it's not got around to accepting() enough of the pending connections
747 yet. This is the behaviour anyway under Linux, where the listen()
748 argument is ignored; but not under BSD and on systems such as
749 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
750 YAZ-based servers should now be uniform across operating systems in
753 yaz-marcdump uses 64-bit file access on some systems. This is enabled
754 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
755 This allows yaz-marcdump to read large MARC batches (>2 GB).
757 Modified all YAZ source files - except the source which is auto-generated
758 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
761 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
762 corresponding to the existing *_setl() function. These allow option
763 values containing arbitrary valuues.
765 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
766 ZOOM_resultset_sort() in new applications. Its behaviour is identical
767 except that it returns an indicator of whether or not the sort
768 criterion was accepted (0 for OK, -1 for invalid).
772 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
773 MARC output rather than returning "new" buffer.
775 yaz-client warns about unknown init options.
777 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
781 Added support for SRW sort in Generic Frontend Server. Patch
782 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
783 sortKeys - or NULL if none is provided.
785 Fixed bug #307: It was impossible to specify indefinite/no timeout
786 for ZOOM_event. Special timeout value -1 now means indefinite timeout
789 Added support for multiple languages and charsets to be specified in
790 ZOOM. Each charset/language is separated by a blank. If negotiation is
791 in effect in init-response, Option
792 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
793 Code based on patch by Vasiliy Osadchuk.
795 Fixed bug #306: infinite recursion that occurred when calling
796 yaz_log_level_init as the first call (before other log level or
799 Fixed bug in scan handling in front end server: if preferred-Position-In-
800 Response was non-present, a NULL pointer referece was performed.
804 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
805 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
806 now defined for all those error codes. So instead of putting 109 in
807 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
808 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
810 Modified the yaz-marcdump utility to skip garbage bytes between MARC
813 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
815 Program yaz-client now exits and produces an error message if multiple
816 Z39.50 servers are specified on the command line (none or one allowed
819 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
824 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
826 Fixed bug #272: Preserve spacing for CCL terms.
830 Added support for virtual hosts and multiple backend servers for
831 the YAZ frontend server. The configution is XML based and
832 support specificition of CQL to RPN mappings and explain information.
833 See section "Virtual Hosts" in the YAZ manual.
835 Extended OPAC display utility. OPAC display utility renders
836 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
837 to supplement yaz_marc_decode_wrbuf.
839 Fixed a bug in MARC decoder that could caused it to crash for some
840 invalid MARC records. More diagnostics and warnings where added in
841 XML output (warnings, etc are stored in comments).
843 --- 2.0.34 2005/02/08
845 Fixes for UNIX domain sockets. Bug #261.
847 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
849 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
850 Added yaz_marc_subfield_str which defines subfield lead string which is
851 used in YAZ_MARC_LINE format. Default string is blank+$. Added
852 yaz_marc_endline_str which defines end of fields string used in
853 YAZ_MARC_LINE format. Default string is newline.
855 Experimental support for MarcXChange. This format can be produced
856 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
857 http://www.bs.dk/standards/MarcXchange.xsd
859 Added yaz-client commands scansize that sets maximum number of
860 entries to be returned by scan.
862 --- 2.0.32 2005/01/11
864 Added support for SRW scan in yaz-client and Generic Frontend Server.
866 * Added whereInList member to SRW Scan Term.
868 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
870 Fixed NMEM system to return aligned blocks on the smallest boundaries
871 that are suitably aligned for all possible types on the particular
872 architecture YAZ is being built for.
874 --- 2.0.30 2005/01/04
876 Fixed numerious warnings that was issued with newer versions of GCC.
878 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
879 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
882 Make YAZ Generic Frontend Server slightly faster.
884 Enhance (and reduce) logging for Generic Frontend Server.
886 Revert YAZ log system so that it flushes every write operation
887 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
889 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
890 instead of LOG_, due to name clash with syslog(3). LOG_ are still
891 present. New applications should define YAZ_USE_NEW_LOG=1 - this
892 will effectively disable old definitions.
894 --- 2.0.28 2004/11/09
896 Added yaz_log_time_format which specifies log format using
899 Added yaz_log_module_level which returns mask for a module. Value
900 is non-zero mask a if module is enabled; zero if disabled.
902 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
903 in include/yaz/cql.h.
905 Fixed bug #176: Dont throw diagnostics on empty SRU args.
907 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
909 Fixed bug #172: RPM builds does not enable SSL.
911 Doxyfile.in part of dist. Doxyfile generated by configure.
913 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
914 are given and the corresponding component does not exist.
916 Extend CCL documentation in YAZ reference. Describe r=r.
918 --- 2.0.26 2004/10/01
920 Fixed MARC->MARCXML conversion to properly deal with
921 fields, subfields, indicators having non-ASCII characters.
923 Fixed MARC->MARCXML conversion so that ASCII control characters
924 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
927 Added YAZ GFS support for conversion from Z39.50 surrogate
928 diagnostics to SRW surrogate diagnostics.
930 Bug fix: YAZ GFS did not return schema in explainResponse.
932 --- 2.0.25 2004/09/30
934 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
935 now converts recordSchema to elementSetName as well as schema URI.
937 Fixed bug in COMSTACK that prevented HTTP request packages from being
940 --- 2.0.24 2004/09/29
942 Added CCL facility r=r "range" which is similar to r=o "ordered" but
943 does not require white-space before and after the dash in a range, e.g.
944 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
947 Fixed a few AC_TRY_LINK configure tests that did not operate properly
948 due to new GCC removing "redundant" code.
950 Added yaz-client commands scanpos and scanstep that sets preferred
951 position and step-size for scan.
953 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
955 Added CCL utility ccl_qual_buf which parses one or more CCL
956 spec lines in a buffer.
958 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
959 of name and value - ignoring empty lines and comments.
961 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
963 Added odr_get_element_path which returns current element path for an
964 ODR handle. This utility is useful in error handling or user-defined
967 Added ODR_PRINT utility odr_set_stream which is is a more generic
968 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
969 to a write function and pointer to close function. The close function - if
970 non-NULL - will be called during odr_destroy.
972 Fixed bug in CCL parser where truncation char was not removed from
973 right side when truncation=both was in effect.
975 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
978 --- 2.0.23 2004/08/11
980 Fix buffer overrun in CQL parser when dealing with proximity (%).
982 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
983 to UTF-8/UCS conversion is now only based on codetables.xml.
985 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
987 --- 2.0.22 2004/08/06
989 Add support for more "commit changes" in ZOOM (uses Extended Services).
991 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
994 Yet another small fix for configure of SSL.
996 --- 2.0.21 2004/05/14
998 Fix SSL libs for configure when --with-openssl=DIR is given.
1000 --- 2.0.20 2004/05/10
1002 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1004 SSL comstack now uses yaz.pem certificate file on server side
1005 by default. Certificate filename can be configured by calling
1006 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1008 Fix bug regarding multiple calls to ZOOM_connection_connect.
1010 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1012 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1013 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1015 ZOOM now allows inspection of X509 peer certificate for verification.
1016 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1018 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1019 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1020 as "modular" but it simplifies things.
1022 Added cs_get_peer_certificate to that returns peer X509 PEM.
1024 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1025 NULL if SSL is unavailable.
1027 Documentation about MARC decoding tools.
1029 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1031 --- 2.0.19 2004/03/30
1033 Rename CHANGELOG to NEWS to follow GNU style packing.
1035 Fix bug with missing initialization of member in init_diagnostics.
1036 This bug affects threaded version of GFS server.
1038 --- 2.0.18 2004/03/20
1040 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1043 Ensure zlib.dll is packed with Windows install.
1045 --- 2.0.17 2004/03/17
1047 Fix encoding of xsd:string to use text instead of CDATA.
1049 Fix endless loop in CQL parser with unbalanced ".
1051 Use a more compact way to store MARC-8 conversion tables.
1053 --- 2.0.16 2004/03/16 Debian only
1055 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1058 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1063 --- 2.0.15 2004/03/01
1065 Another fix for decoding of XML packed records.
1067 --- 2.0.14 2004/02/25
1069 Fixes for Chunked encoding. White space not ignored after length spec.
1071 Update NS and use default NS for SRW diagnostic elements.
1073 --- 2.0.13 2004/02/23
1075 Implement ZOOM_resultset_cache_reset which resets record cache.
1077 Implement ZOOM_resultset_sort which sorts a result set.
1079 Implement chunked HTTP transfer.
1081 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1083 --- 2.0.12 2004/02/16
1085 Added member 'schema' to bend_explain_rr structure so that backend
1086 can specify explain record identifier. Defaults to Zeerex 2.0.
1088 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1090 --- 2.0.11 2004/02/16
1092 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1095 Added init command for yaz-client which sends "extra" init request.
1097 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1098 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1100 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1102 Make ZOOM error code for "invalid query".
1104 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1106 --- 2.0.10 2004/02/05
1108 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1111 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1113 Added option -p <file> to make Generic Frontend Server to write PID file.
1115 Added option -D to put Generic Frontend Server in background on its own.
1117 Make ZOOM C recognize option "password". If unset, "pass" is used
1118 (for backwards compatibility).
1120 Fixed a bug in Generic Frontend Server that could make it crash if a
1121 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1124 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1125 Must be issued before open, in order to be in effect.
1127 --- 2.0.9-6 2004/01/12 Debian/Windows
1129 Make the SRU server more picky WRT unknown params, etc.
1131 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1133 New YAZ client command, options, that sets Z39.50 options.
1135 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1136 options from a string of tokens (one token for each option bit).
1138 Update SRW diagnostic code messages.
1140 --- 2.0.9-5 2004/01/07 Debian/Windows
1142 Handle user defined stylesheet for SRW/SRU.
1144 --- 2.0.9-4 2004/01/06 Debian/Windows
1146 Fix bug in decoding of Content-Length.
1148 --- 2.0.9-3 2004/01/06 Debian/Windows
1150 Fix a bug with decoding of XML packed records.
1152 --- 2.0.9-2 2004/01/05 Debian only
1154 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1156 Fix bug in SRW/SRU diagnostics decoding.
1158 --- 2.0.9 2004/01/05
1160 Fixed bug in Generic Frontend Server which could drop records exceeding
1161 preferred message size. Reported and fixed by Irina Dijour.
1163 Fixed calculation of package size for structured records in Generic
1164 Frontend Server. Reported and fixed by Irina Dijour.
1166 Fixed namespace for SRW/SRU diagnostics.
1168 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1170 --- 2.0.8 2003/12/22
1172 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1173 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1176 CQL changes to reflect recent changes to the specification:
1177 * Documentation talks about context sets instead of index sets.
1178 * Documentation talks about indexes instead of qualifiers.
1179 * The CQL-to-PQF transformer's configuration file now uses
1180 "index.set.name = <attributes>" instead of the old form
1181 "qualifier.set.name = <attributes>". (Both forms are still
1182 understood but the latter is deprecated.)
1183 * CQL terms with no explicit index specified are now interpreted as
1184 cql.serverChoice instead of srw.serverChoice (which of course
1185 behaves exactly the same.)
1187 --- 2.0.7 2003/12/16
1189 MARC conversion can now generate ISO2709 output in another
1190 character set. yaz-marcdump uses this facility if you invoke it
1193 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1194 functions from there can be used from C++.
1196 --- 2.0.6 2003/12/04
1198 Frontend server now transfers memory from decoded packages to stream
1201 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1202 references to show up.
1204 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1205 the ZOOM Abstract API. The older names for the same options are still
1206 also supported for the benefit of old applications.
1208 ZOOM-C supports "implementationId" and "implementationVersion" options
1209 to go along with "implementationName". These allow the user code to
1210 specify identification strings to be sent to servers.
1211 Add OID for the new ExtLite attribute set.
1213 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1214 as requested/supplid by Ere Maijala <ere@atp.fi>
1216 For generic frontend server, reverse the order of
1217 "toolkit-supplied / application-supplied" strings sent as implementationId,
1218 Name and Version. Also, remove the spaces around the slash. This brings
1219 the GFS in line with the behaviour of ZOOM-C on the client side.
1221 Add function ZOOM_scanset_display_term.
1223 yaz-client shows scan displayTerm if present.
1225 Utility yaz-iconv is now installed by default along with the man page
1228 Extend configure check for OpenSSL to use pkg-config where available (such
1231 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1232 server to specify uid/gid/mask for socket using the format
1233 unix:[user=uid,][group=gid,][umask=mask,]file=path
1234 If file= is omitted the existing format is assumed, e.g.
1236 in which case the mask is 0666 (rw for everybody).
1238 Major restructure of YAZ source. All source in libyaz is in src directory.
1239 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1240 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1242 Added man page for utility yaz-marcdump (used to be called marcdump).
1243 yaz-marcdump is installed by 'make install'.
1245 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1246 of incoming package failed.
1248 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1250 Change prototype of odr_perror: add const to message string.
1252 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1254 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1255 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1256 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1257 DNS lookup. There should not be any compatibility problems with this
1258 assuming that blocking=1 or 0 is used.
1260 Fix bad reference in UNIX comstack in function cs_addrstr.
1262 Fix for compilation on AIX.
1264 The generic front-end server (server/seshigh.c) now supports returning
1265 Init diagnostics to the client in User-information-field, in
1266 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1269 --- 2.0.4 2003/09/04
1271 Allow any CQL relation (not just all,any,exact,scr).
1273 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1274 that features the same UI.
1276 Implemented command update0 in YAZ client which is equivalent to
1277 update but uses old of Ext Update ASN.1.
1279 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1280 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1281 Previously no OID was used for this info.
1283 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1284 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1285 returns 'malformed search term' otherwise.
1287 SortResponse member resultCount now set to NULL in sort handler of
1290 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1293 Add three new utility functions for translating OIDs between various
1294 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1295 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1296 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1297 char *oid_to_dotstring(const int *oid, char *oidbuf);
1298 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1300 Reverted modifications for ES Update definition for z_IU0Update
1301 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1302 is back to YAZ 2.0.2.
1304 String value attributes for CCL parser.
1306 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1307 which their FirstSearch server returns in Init responses, sometimes
1308 carrying useful diagnostic information when Init fails. This has the
1309 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1310 "z39.50/oclcui.asn", where its definition is somewhat different from
1311 what OCLC document on their web-site, as required to interoperate with
1314 Support for anonymous authentication in yaz-client. Use the command
1317 * Fix the OID of the Index Data-local "admin" Extended Service from
1318 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1319 the 1000, which indicates a locally-defined OID, was a mistake.
1321 --- 2.0.3 2003/06/20
1323 Fix CCL directive @case handling so that it affects string match for
1324 both CCL keywords and qualifiers.
1326 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1327 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1328 Decoder has been updated with ASN.1 changes as listed in
1329 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1330 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1331 z_IUUpdate, remains unchanged.
1333 ZOOM_record_get may now return a record in a specific character set.
1334 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1335 "from" is the character set of record as returned by target. "to" is
1336 the character set to be returned. If omitted, "to" is UTF-8.
1338 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1340 New ODR utility, odr_getelement, which returns name of element for
1341 which encoding/decoding failed.
1343 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1344 in cases where a required element was omitted.
1346 Bug fix: some MARC8 sequences were not converted.
1348 New ZOOM option "step" which specifies number of records to be
1349 retrieved in one chunk. Used in conjunction with "start" and "count".
1351 SRW support for yaz-client. Use scheme http: to use it, e.g.
1354 yaz-client no longer does (un)intelligent character set conversions
1355 by default. Can be enabled with charset and marc_charset commands.
1357 xmalloc trace fix for 64-bit systems such as DEC alpha.
1359 Solaris 2.6 compile fix.
1361 New function, cql_strerror() translates SRW error codes, as returned
1362 by cql_transform_error(), into human-readable English strings. Used
1363 in yaz-client diagnostics when appropriate.
1365 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1366 converts it into a type-1 query which is sent to the server. This
1367 makes CQL available for use with all Z-servers, as opposed to the tiny
1368 minority that can handle CQL queries themselves.
1370 --- 2.0.2 2003/04/28
1372 New Debian package layout similar to the Redhat Package layout.
1374 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1375 and search result respectively.
1377 --- 2.0.1 2003/04/25
1379 Redhat package is now several packages: libyaz (runtime libraries),
1380 libyaz-devel (development and documentation, and yaz (utility programs).
1381 Package spec file by Morten Bøgeskov.
1383 New member 'schema' in struct bend_fetch_rr which the name of requested
1384 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1385 handler MAY set this to reflect the schema of the returned record.
1387 New member 'display_term' in struct scan_entry. GFS now sets member entries
1388 and allocates scan entries to be filled by user scan handler. In previous
1389 version, entries member was allocated by the scan handler. That still works,
1390 but the GFS will ignore member display_term - assuming it was NOT set by
1391 the handler. The fact that the GFS now allocates the entries both allows
1392 for new members and makes a scan handler easier to write.
1394 Fix CQL lex buffer overflow.
1396 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1397 SRU default recordPacking is string.
1399 SRU protocol support for frontend server.
1401 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1403 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1405 Added scan for the ZOOM shell (zoomsh).
1409 * String Identifers for Schemas (Amendment 5).
1410 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1411 Old definition for schema
1412 Odr_oid *schema; /* OPT */
1417 Z_InternationalString *uri;
1418 #define Z_Schema_oid 1
1419 #define Z_Schema_uri 2
1422 * resultCount parameter to Sort Response (Amendment 1).
1423 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1425 Support for SRW 1.0 over HTTP. This is an optional feature and
1426 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1429 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1430 on the same port. SRW SearchRetrieveRequests are mapped
1431 to bend_init,bend_search,bend_fetch,bend_close.
1433 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1435 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1436 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1438 ZOOM connections are SRW based if schem http is used for hostname
1439 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1440 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1442 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1443 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1444 distance=n, order=true/false, relation=le, prox unit=word. If
1445 n is omitted, distance 1 is used.
1447 Fixed problem with C compiler include path in wrong order.
1449 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1450 on Solaris. Patch from Ko van der Sloot.
1452 New MARC decode API. All new functions operate on a yaz_marc_t
1453 handle. The most important new functions are: yaz_marc_create,
1454 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1455 decode and destroy respectively. Decoder can produce formats
1456 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1457 include/yaz/marcdisp.h.
1459 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1460 to UTF-8, UCS-32, wchar_t or Latin-1.
1462 * Prototypes for yaz_iconv_-functions moved to separate header
1463 include/yaz/yaz-iconv.h.
1465 Make a few private functions 'static' in unix.c. This prevents
1466 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1468 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1469 are set when Init Response is received.
1471 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1472 but returns diagnostic set as well.
1474 New function yaz_strerror which is a portable wrapper for
1475 strerror/strerror_r/GetLastMessage.
1477 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1478 is returned for MARC. If type is "oai", then OAI MARC is returned.
1480 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1483 --- 1.9.2 2002/11/26
1485 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1487 Fix bad race conditions on SIGTERM and terminate gracefully in
1490 Move retrieval (data1) module to Zebra since nobody seems to be
1493 Add GRS-1 render for ZOOM using same format as yaz-client.
1495 --- 1.9.1 2002/10/05
1497 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1499 Fix broken ESpec handling in data1 module.
1501 SGML reader parses comments and makes them part of the data1 tree.
1503 Added several type casts so that YAZ compiles as C++ code.
1505 ZOOM didn't handle PDU encoding failures properly.
1507 Added more Bib-1 diagnostics (approved extensions).
1509 GNU configure: better check for iconv.
1511 More portable use of accept, getpeername. Check for socklen_t. Use
1512 int/size_t if socklen_t is not defined.
1516 PQF parser rejects bad queries - including those with extra
1517 characters in them. PQF parser used to silently ignore that.
1518 Cleaner API for PQF added, which allows you to get detailed
1519 error information for bad queries (see yaz/pquery.h).
1521 Fixed bug in ZOOM_record_get for type "database".
1523 Implemented mini iconv library supporting conversions between
1524 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1526 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1528 --- 1.8.9 2002/08/20
1530 Fixed ZOOM C record cache so that preferredRecordSyntax and
1531 elementSetName is used to check for already fetched records.
1533 --- 1.8.8 2002/08/02
1535 Added three members in bend_initrequest structure to facilitate
1536 character set negotiation.
1538 Fixed a bug in frontend server that could cause indefinite
1539 loops under rare conditions.
1541 Revised character set utilities (charneg.h) so that encoding
1542 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1544 For PQF, directive @term <type> sets term type for Scan/Search.
1545 Here <type> is general, string, numeric, null. The term type
1546 is inherited - just like @attr.
1548 New call odr_set_charset that sets character set conversion for
1549 international-strings on a ODR stream. Prototype is:
1550 int odr_set_charset(ODR o, const char *to, const char *from);
1551 The InternationalString is still represented as C string in YAZ
1552 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1553 won't). On the protocol level, you can use any encoding.
1555 Support for UNIX sockets in ZOOM.
1557 Solaris recv sometimes returns errno == ENOENT. It is treated as
1558 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1560 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1561 both client and server. Code by Morten Bøgeskov.
1563 --- 1.8.7 2002/05/22
1565 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1566 that they can be used directly from Visual Basic. You must recompile
1567 your windows APP if you're using ZOOM.
1569 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1570 Commands "lang" and "charset" sets language and character set respectively.
1571 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1572 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1574 Attributes from multiple CCL fields may be OR'ed rather than merged
1575 using directive "@field or". Fields are still merged by default -
1576 equivalent to "@field merge".
1578 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1581 Fixed bug in zget for parameter ExtendedServicesResponse.
1585 --- 1.8.6 2002/03/25
1587 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1589 Client displays USR.1:SearchResult-1 (hits per term).
1591 Additional Search Info for search in Generic Frontend Server.
1593 Fixed CCL parsing of "field=s".
1595 WIN32 installer - using the excellent NSIS software from nullsoft.
1597 Fixed CCL parsing of "field = - <number>".
1599 Added function yaz_marc_decode that decodes MARC for line mode
1600 display or XML (similar to that used by JZKit).
1602 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1603 Z39.50. But ISO/ILL was, however.
1605 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1606 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1608 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1609 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1611 --- 1.8.5 2002/02/03
1613 New YAZ client features: Command completion and new commands:
1614 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1615 Code provided by Jacob Poulsen.
1617 New call oid_trav, that visits all registered OIDs via callback.
1619 Function ZOOM_record_get now returns const char pointer rather than
1620 void pointer. It saves a lot of type casts.
1622 For YAZ client, command "auth" now allows you to set authentication
1623 in IdPass style. It is enabled when three tokens are given - order
1624 is user, group and password.
1626 Fix memory leaks in MARC record handling for ZOOM.
1628 New option for YAZ client, -k <kilobytes> that sets
1629 maximum record size. Similar to -k option for generic frontend
1630 server and yaz-ztest.
1632 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1634 Prefix query parser reports "fail" when bad attribute set is given.
1636 Fix in MARC decoder. Proximity logging. Fix for attribute set
1637 in scan handler for server. Patches by Shigeru Ishida.
1639 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1642 Configure option --with-openssl=<dir> now works when a directory is
1643 specified. Patch provided by Morten Bøgeskov.
1645 New option for YAZ client, -u <auth>, that sets authentication.
1647 ZOOM fix: error information was sometimes "missing", since error
1648 was cleared/reset too when it shouldn't.
1650 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1652 --- 1.8.4 2002/01/04
1654 Scan for ZOOM API. New object ZOOM_scanset. New functions
1655 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1656 ZOOM_scanset_destroy.
1658 New ZOOM function, ZOOM_connection_last_event, that returns type
1659 of last event (such as "receive data", "send data", "apdu received",
1662 New ZOOM option, schema, that specifies schema for retrieval.
1664 New CCL feature. Qualifiers can be aliases for one or more
1665 other qualifiers (if more than one is given, OR is used).
1667 ZOOM uses named result sets if target supports it.
1669 Two new YAZ client commands: . (dot, which sources a script of YAZ
1670 client commands), and ! (to execute shell command.). Implemented
1673 Working on Debian packages.
1675 --- 1.8.3 2001/11/19
1677 YAZ client enables named result sets only if target supports it.
1679 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1681 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1682 with key="host" to get same result.
1684 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1685 Function Z3950_resultset_record(s) returns references to records
1686 "owned" by resultset. To become owner use Z3950_record_clone.
1688 Function z_ext_record handles Extended Services. Thanks to
1691 --- 1.8.2 2001/11/12
1693 CCL Parser fix: ignore token comma when dealing with and-lists.
1695 Documentation updates for COMSTACK.
1697 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1698 Changed prototype Z3950_records. For some functions, int parameters
1699 were changed to size_t.
1701 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1704 New MARC decode/display function, marc_display_exl, which properly rejects
1705 non-ISO2709 records. YAZ client uses it.
1707 --- 1.8.1 2001/10/29
1709 Fix bug: local attribute set wasn't set correctly in PQF strings.
1713 * Old Z39.50 codecs no longer supported.
1715 Added ZOOM C binding. See http://zoom.z3950.org/
1717 Renamed states for COMSTACKs to avoid confusion with events.
1719 Implemented cs_look and proper cs_rcvconnect.
1721 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1723 Configure detects POSIX threads on OpenBSD.
1725 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1726 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1728 When error is returned from present handler, non-surrogate diagnostic
1729 is returned in present response (and fetch handler is no longer called).
1731 * Minor adjustments to pquery parser (PQF). Token characters may be
1732 escaped by using backslash (C-style).
1734 PQF parser allows string attribute values to be specified. For @attr,
1735 non-numeric characters after the equal-sign are treated as strings
1736 (e.g. @attr 9=title).
1738 CCL trunction character may be defined (@truncation in file)
1740 * function zget_ExtendedServicesRequest sets waitAction to
1741 waitIfPossible (was wait).
1743 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1746 CCL operator names may be set in field definition files (CCL_bibset).
1747 See ccl/bib1 for an example.
1749 Fixes in ASN.1 compiler for C++ compatibility.
1751 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1752 and "op_or" to avoid conflict with C++.
1754 Fixed problem with GNU readline detection on Redhat 7.0.
1756 Added step-size for Scan backend handler.
1758 Fixed bug that made the frontend server crash when no attribute
1759 set was specified for scan.
1761 Front-end server automatically switches to original working directory
1762 when installed as an NT service. Previously -w had to be specified to
1765 Added extended attributes for retrieval module (data1), so that data1
1766 records carry d1_readXML/SGML attributes. d1_read also supports
1767 null-data rules ( <tag/>)
1769 On UNIX when POSIX threads are available, a separate library libyazthread
1770 is created. Programmers should link with that library and the yaz library
1771 when using threads. The reason for the split was that some applications
1772 on Linux, such as Apache, doesn't work well when using shared objects that
1775 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1776 (or any frontend server) in SSL mode by specifying ssl: followed by
1777 address. Only tested on UNIX.
1779 Added feature for CCL module. Virtual structure s=al or s=ol generates
1780 and-list and or-list respectively instead of phrase search.
1784 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1785 log_mask_str. This was done to avoid name conflicts with other libraries
1786 (such as other PHP extensions).
1788 Added raw OID member for preferred record syntax (request_format_raw)
1789 and returned record syntax (output_format_raw) for backend fetch method.
1791 Config file yaz-config now accepts options so that it returns specific
1792 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1794 Shared library support for UNIX using GNU libtool.
1796 * Modified backend interface. Request/Response struct's replaced by
1797 one read/write C struct. For example bend_fetchrequest and
1798 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1799 Every handler - even search has to be registered in bend_init
1800 handler. This means that the YAZ library no longer refers to
1801 external functions and it makes it possible to make the whole
1802 thing a single DLL/SO.
1804 Added Segment handler for backend server.
1806 Added Zmbol/Zebra administrative functions to YAZ client.
1808 Threaded frontend server on UNIX (when POSIX Threads are available).
1809 Starting the server with option -T enables multi-threading.
1813 Added configure option --enable-comp/disable-comp to control use
1814 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1815 located in sub directory asn.
1817 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1818 in ${exec_prefix}/bin along with the other programs yaz-client and
1821 GNU automake used to maintain makefiles.
1823 Added several OID's.
1825 Changed retrieval module so that we can load records with no abstract
1826 syntax defined. Tagpaths in these records are fully composed of string
1829 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1833 On UNIX, the generated makefile now supports a proper 'make install'.
1834 The prefix can be set via GNU configure to set the install location
1835 (default is /usr/local).
1837 * YAZ programs client and ztest were renamed to yaz-client and
1838 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1839 locations, such as /usr/bin,/usr/local/bin,etc.
1841 * YAZ Header files were moved from include to include/yaz. YAZ Header
1842 files are referred to as include <yaz/log.h> rather than <log.h>.
1843 The YAZ include path (-I ..) is therefore the same as before. Programmers
1844 should update their #include statements or use -Ipath/include/yaz
1845 instead. The main motivation for doing this change is that YAZ header files
1846 can be installed in "standard" locations /usr/include,/usr/local/include
1847 without introducing conflicts, since ALL YAZ header files are stored
1848 in subdirectory yaz (under /usr/include for example).
1850 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1851 rather than project/workspace files. We switched because project files
1852 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1855 Changed name of logging function, logf, to yaz_log, to prevent name
1856 clash with some math-log functions. The YAZ header log.h defines logf
1857 to yaz_log (#define) so there should be no incompatibilities by this
1860 Added bend_start/bend_stop handlers for server. These handler are
1861 called on start/stop of server. For windows they are called whenever
1862 a service is started/stopped.
1864 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1865 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1866 in util/yc.tcl. The auto-generated C code structures are, in a few
1867 cases, incompatible with the old decoders. There are differences in the
1868 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1869 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1870 The preprocessor variable ASN_COMPILED is defined when the compiled
1871 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1872 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1873 wish to use the old encoders/decoders you can specify --disable-yc
1876 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1877 version so that it supports both new - and old version of DB Update
1879 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1880 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1881 change. The name parameter can be set to 0 in which no name is specified
1882 for the construction. The macros odr_implicit and odr_explicit sets name
1883 parameter to zero for the construction involved. New macros
1884 odr_implicit_tag and odr_explicit_tag are similar to the others,
1885 except that a name parameter is added. For programmers' that don't use
1886 ODR they probably only need to change the call to z_APDU and z_External.
1888 Added access control facility by interfacing the TCP wrapper library.
1889 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1890 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1891 name of the daemon and enables the access control as specified in
1892 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1894 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1895 den Dool <H.M.vdnDool@kub.nl>.
1897 Added reference ID parameter to most functions in server API - refer
1898 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1900 Changed name of ccl library to libccl.a (was ccl.a).
1902 Fixed bug in decoder for Explain (Category TargetInfo).
1904 Added support for GNU readline in client. Thanks to Jacob Poulsen
1905 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1907 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1908 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1909 IMPLEMENTATION! This change was made to the development version before
1910 the ZIG decided to retract the amendment. If any users MUST be
1911 compatible with the original Update definition, PLEASE CONTACT US, and
1912 we will include a separate definition corresponding to the old Update
1913 ES. Note that because of the change to the ASN.1 of the
1914 TaskPackageRecordStructure we cannot define a single structure that
1915 will support both versions.
1917 * Added const modifier to buffer parameter for some ODR/BER encoding
1918 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1919 completeWAIS, odr_dumpBER.
1921 Fixed bug in client.c which caused a crash when a scanResponse didn't
1922 contain positionOfTerm.
1924 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1925 * will cause an error in a client if a non-YAZ target sends both a
1926 * list of Scan entries and non-surrogate diagnostics.
1928 Retrieval module enhancements. Tag sets may be typed in the reference
1929 to it. From the .abs-file the "tagset" directive takes a third optional
1930 integer type for the tag set referenced. From a .tag-file the "include"
1931 directive takes a third optional type as well. The old "type" directive
1932 in the tag set itself is still recognized but acts as the default type
1935 Backend interface change. Individual Scan terms returned from bend_scan
1936 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1937 in include/backend.h.
1939 Retrieval module enhancements. Multiple tag sets and attribute sets may
1940 be specified in abstract syntax specs. Revised the error/warning for
1941 logging messages reported by the retrieval module when reading the
1944 Object Identifier system (oid_..) changed. The API is backwards
1945 compatible but the oid-routines now allocates new OID's when needed.
1946 Raw OID's may be specified in oid_getvalbyname.
1948 YAZ now uses GNU configure to generate Makefile(s).
1950 * Minor changes in some of the member names of DeleteResultSetRequest and
1951 DeleteResultSetResponse. See include/proto.h.
1953 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1954 and added member 'languages' in TargetInfo (which was missing).
1956 Changed the way attribute sets are handled in the retrieval
1957 module. These are now cached, just like the abstract syntaxes
1960 Changed YAZ so that it links with compiled ASN.1.
1962 Added Explain-schema definitions and mapping routines. The following
1963 Explain categories have been implemented: AttributeDetails,
1964 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1966 Fixed minor bug in Windows version of Server Library.
1968 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1970 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1972 Added EXTERNAL: UNIverse Resource Report (non-standard).
1974 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1975 ENUMERATED and SET OF.
1977 * Added 'const' to some of the char pointer arguments for the
1978 functions, data1_read_node, data1_getelementbytagname,
1979 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1982 Fixed bug in data1_insert_taggeddata - the last_child member of
1983 parent wasn't initialised.
1985 * Changed data1_read_record and data1_read_node so that the supplied
1986 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1987 doesn't refer to any parts of the "SGML"-buffer.
1989 Fixed bug in server library (Windows version of statserv_remove).
1991 * Changed code so that it compiles as C++. The type definition
1992 of Odr_fun which is a member of Odr_arm was changed. The result is,
1993 that an explicit typecast is needed for the fun pointer when
1994 using Odr_arm - as in:
1995 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1997 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1999 Implemented the new structured date and time definition as approved
2000 by the ZIG. Added schemaId element to the specificTag in Espec-1
2001 (also approved at the last ZIG). Thanks to RVDM.
2003 Added some Object identifiers (RVDM).
2005 Changed the Update Extended Service (RVDM).
2007 Added command "refid" to client which specifies referenceId for
2008 the following requests.
2010 Implemented extended service handling for server. See ztest.c
2011 for an example as well as backend.h. New handlers are registerd
2012 in the Init handler.
2014 * Changed interface for sort in server.
2016 Added new members to statserv_options_block. It allows a server
2017 to read options from another source than just the command line. Thanks
2018 to Charles Woodfield.
2020 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2021 renamed to zboolean. Some C++ compilers complained about the name.
2023 Minor changes to gils.abs. Added index 's' (sort) on title
2024 and date/time-last-modified.
2026 --- 1.4pl2 1998/1/30
2028 Fixed bug in server library regarding inetd mode (-i). This bug
2029 was introduced by release 1.4.
2031 --- 1.4pl1 1998/1/29
2033 Added sort facility in client and backend server interface.
2035 Fixed problem with dependencies in Makefile(s).
2037 Fixed bugs for encoders/decoders of extended services and
2040 Implemented sub-tree feature for schemas. Sub-trees are
2041 referenced in *.abs-files. See explain.abs for an example
2042 of the use of this feature.
2044 Modified bib1.att; local attributes for ANY didn't include
2045 ANY itself (only affects use of the retrieval module).
2047 Fixed bug in plain SGML reader in function data1_read_node:
2048 tags with prefix "var" was incorrectly interpreted as variants.
2050 Added feature "sub-schemas" to enable references to - and definitions
2051 of - group of elements.
2053 * Removed member parent from type data1_element (in data1.h).
2055 Implemented function odr_nullval() that returns the value of
2058 * Removed member num_children from data1_node (in data1.h).
2060 Made NT service interface part of the server library. The
2061 function statserv_main uses the NT service when required and
2062 calls the statserv_start / statserv_close routines.
2064 Routine zget_SearchRequest and zget_PresentRequest fills
2065 resultSetName/Id member with "default" instead of "Default".
2067 Fixed memory leak in server. Request queue member wasn't freed.
2069 Fixed nmem_exit so that memory is freed.
2073 Revised the CCL parser utility to be thread safe.
2075 Added function, oid_ent_to_oid, to replace the function
2076 oid_getoidbyent, which is not thread safe.
2078 * Added nmem_init and nmem_exit to initialize and release
2079 NMEM resources. Function nmem_init should be called once in the
2080 initial thread before NMEM/ODR is used. statserv.c and client.c
2081 have been changed accordingly. The change was necessary to make
2082 NMEM thread safe. The NMEM memory pool is shared amongst threads
2083 in a process. Unix-based applications will still work fine without
2086 Added NT Services interface for the the Z39.50 (statserv) Server.
2087 Refer to the ztest.c source on the usage.
2089 Windows 95/NT port using MSVC5.0. Project files are included in the
2092 * Defined new 'global' handle for the retrieval (data1) system. The
2093 new handled, data1_handle, describes the state of the data1 system.
2094 This handle is passed as first argument to virtually all
2095 data1 related routines. The functions data1_create and data1_destroy
2096 creates and destroys a data1 handle respectively.
2098 Added ODR encode stream member to all backend request structures
2099 init, search, scan etc. This stream should be used to allocate all
2100 memory used for the response when thread safe operation is needed.
2102 Changed the comstack utility, cs_addstr, to be thread safe. The
2103 returned hostname string returned by the function is now part the
2106 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2107 function. The cs_straddr takes a COMSTACK handle as argument, so this
2108 function must be used after cs_create and before bind/connect.
2109 This function is thread safe.
2111 Moved test server to 'ztest' directory - generic server code still
2112 in 'server' directory.
2114 Made prefix query (pquery.c) utility thread safe.
2116 Added new function modifier YAZ_EXPORT to 'export' public DLL
2117 functions when using windows (see include/yconfig.h).
2119 Added definitions to the OID database (util/oid.c) (RVDM).
2121 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2123 Added call to ccl_rpn_delete in client program.
2125 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2126 release of RPN structure.
2128 Added support for C++, headers uses extern "C" for public definitions.
2129 With input from RVDM.
2131 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2132 Thanks to Ronald van der Meer (RVDM).
2134 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2136 Added support for private extensions to the OID database
2137 (oid_setprivateoids()). Thanks to RVDM.
2139 Added optional, physical ANY (key replication)
2141 Fixed null-reference problem in GRS-1 output filter.
2143 Proximity operator added to Prefix Query Format (PQF).
2145 In test client command "base" accepts multiple databases.
2147 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2151 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2153 Smallish bug-fixes in the new encoders/decoders (explain).
2155 Bug fixed in DeleteRequest.
2157 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2159 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2161 Added SOIF syntax (using private OID for now) to retrieval module and client.
2163 Added Update extended service.
2165 Added SearchResult-1 additional info structure.
2167 Added optional CCL (ISO8777) interpreter as separate module. Available
2170 --- 1.2 1996/6/10 (1st anniversary release)
2172 Added Summary record syntax. Lightly tested.
2174 Added OPAC record syntax. Untested.
2176 Added ResourceReport service encoders/decoders. Untested.
2178 Fixed bug in z_Unit - wrong tagging on unitSystem.
2180 Fixed bug in the DiagRecs decoder.
2182 Added options for max PDU size and session timeout to frontend-server.
2184 Added documentation of query-language parsers and other supporting utilities.
2186 [frontend-server] Added Attribute set to the bend_scanrequest API.
2188 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2189 surrogate diagnostics were generated.
2191 [retrieval] Allow multiple local values for attribute.
2193 [retrieval] Allow multiple attributes per element in .abs files. index type.
2195 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2197 --- 1.1pl2 1996/4/10
2199 Minor changes, mostly specific to Zebra's requirements (retrieval)
2203 Repaired bug in frontend server when running multiple listening
2204 endpoints in dynamic mode.
2206 z_External() now won't break if a known, ASN.1 value comes encapsulated
2207 in an octet-string. The value will pass through unmodified in an Odr_oct.
2209 Added a bit of code to the demo client to decode & display
2210 ASN.1-structured records represented in the octet-aligned branch of
2211 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2213 Added z_ext_getentbyref() to the ASN module. Doc updated.
2215 * Completed the SCAN definition in the ASN module. This may break SCAN
2216 code based on older YAZ-versions at compile-time. The fix is easy -
2219 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2220 under the SCAN definition. Remember to initialize this, server-people.
2222 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2223 that this does not extend to ODR and ASN.
2225 Comstack allows insertion of established socket (primarily for
2226 inetd-operation of servers). Doc updated.
2228 Front-end server can now start from the inetd in TCP mode. Doc
2231 --- 1.0pl4 1996/1/24
2235 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2236 the rank and record number.
2238 Adjustments to the frontend server.
2240 Fixed diagnostic BER dumper. It ignored the file argument.
2244 Various changes to retrieval module.
2246 Changed the union discriminators of the protocol files from enums to
2247 ints paired with #defines.
2249 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2252 *Changed operator in the RPN structure to 'roperator', again to avoid a
2255 Fixed problems in Explain decoders/encoders.
2257 --- 1.0pl2 1995/12/6
2259 Memory bug in log module fixed.
2261 --- 1.0pl1 1995/12/5
2263 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2265 Bug in Explain DatabaseInfo module fixed.
2267 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2271 The shift to v1.0 signals that we now consider the *core* functionality
2272 of YAZ reasonably stable (the core being more or less equivalent to
2273 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2274 tested (Explain not at all - though that will happen soonish).
2276 Minor changes to code to support Windows port.
2278 Various minor changes after we're getting to use GRS-1 & co. more.
2280 Added Espec-1 format.
2282 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2283 of the protocol and it cannot be selected when encoding (maps into 'string'
2284 when decoding). Needed to talk to some servers.
2286 Demo client can request simple element set names.
2288 Added Diagnostic Format encoders/decoders.
2290 Added simple Close handling to frontend server (no hooks for resource
2291 reporting yet), and demonstration client.
2293 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2295 --- 1.0b3 1995/08/24
2297 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2298 handled incorrectly when records were requested in the searchResponse. This
2299 will only affect you if you use the frontend-server.
2301 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2302 Test-client will ask for and print GRS1. Ztest will return dummy records
2305 Added Explain encoders/decoders to the service-level API. Untested.
2307 Added Extended Services: Item Order encoders and decoders to the Service-
2308 level API. Untested. We could use a recent copy of the pertinent bits
2309 of the ILL protocol to add those bits.
2311 Added diagnostic format 1 encoders/decoders to the service-level API.
2314 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2315 odr_cons.c, which causes a more correct output.
2317 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2318 was always set to 0 when no records were requested in the searchRequest.
2320 * Added better external-handling. This shouldn't harm old code that
2321 *encodes* externals. It can break code that looks for a
2322 'single-ASN1-type' representation, since those types that are known
2323 are now decoded immediately. Look at the SUTRS sample code in
2324 seshigh.c and client.c. Documentation updated.
2326 Handling of structured records in bend_fetchresponse. Length -1 marks
2327 structured record, type is deduced from format field.
2329 --- 1.0b2 1995/06/27
2330 Fairly quick maintenance release to add SUTRS support.
2332 Fixed handling of SUTRS records in the demonstration client.
2334 * Added format field to the bend_fetchrequest and bend_fetchresponce
2335 structures of the backend API (frontend server). When the record is
2336 returned, the value of the format field is mapped to an OID. The
2337 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2338 of the record. The special value VAL_NONE in the bend_request means
2339 that no specific format was requested by the client. Documentation
2340 updated accordingly. Test server (ztest) will return a fixed dummy
2341 SUTRS record if your client requests SUTRS.
2343 Documentation updated accordingly.
2345 You can now set external libraries and RANLIB support in the top-level
2349 First public release.
