3 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
4 is built. Only this DLL depends on the ICU runtime.
6 yaz-ziffy is no longer part of YAZ. It is distributed separately by
7 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
9 Changed license of CCL module to 'Revised BSD'. After consultation with
10 remaining members of the original EUROPAGATE consortium, we are re-issuing
11 the CCL module without a separate license. The software was developed by
12 Index Data as part of a research project. The special license was included
13 to help feed usage information back to the project consortium to support
14 project evaluation. At this time, the project consortium has long-since
15 disbanded, and the majority of the original principals have retired. At the
16 same time, we have significantly modified the software during the following
17 years, to the point where very practically no original code remains. To
18 simplify re-use of the software, we have contacted those members of the
19 consortium who could be reached, and agreed to re-issue the module as a
20 proper part of the YAZ package.
22 Tcl scripts uses /usr/bin/tclsh as preferred shell.
24 CQL closer to being version 1.2 compliant. CQL also allows free-form
25 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
28 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
29 bug could make Extended services handling crash in the ZOOM layer. This
30 bug was only present in YAZ 3.0.18.
34 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
37 yaz-marcdump reads and writes collection wrapped records.
39 Handle OPAC for record conversion module.
41 Fixes for ICU wrapper.
43 Allow ICU libs to be controlled with --with-icu .
47 Added yaz_poll which is a wrapper for select/poll. When poll is available
48 and non-buggy, it is used, by yaz_poll . This allows more than 1024
51 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
52 functionality through an XML based configuration (ICU chain). This system
53 is useful for search facilities such as Pazpar2 and Zebra that needs to
54 perform tokenization of indexed material. The ICU code in a separate
55 library libyaz3_icu.a.
57 Added HTTP tunnel facility for COMSTACK, bug #1752.
58 This is a facility that allows a Web proxy, such as squid, to tunnel
59 Z39.50 traffic. This facility is "transparent" to must applications
60 using YAZ. It's enabled by using pseudo transport connect: followed by
61 the proxy address, followed by command, then follwed by he regular
62 "virtual" addresss. For example,
63 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
65 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
69 Fixed bad memory reference in ZOOM_record - cuased by member not being
70 initialized. This was a problem only in YAZ 3.0.12.
72 Fixed bug in conversion from MARC to XML: Non-XML characters in control
73 fields were not removed.
75 Changed the way C code is generated from codetables.xml. Made a MARC-8
76 conversion trie for each characterSet section rather than codeTable.
77 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
78 of codetables.xml from Larry Dixson, LOC. Bug #1464.
82 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
83 from ZOOM_record_error).
85 ZOOM C function ZOOM_record_get returns record schema for type="schema".
87 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
89 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
91 Better SRW-to-Bib-1 diagnostic mapping.
93 ZOOM C and yaz-client announces SRU version 1.2 by default.
95 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
98 Fixed in yaz_sru_decode to allow other version than 1.1.
100 --- 3.0.10 2007/08/22
102 Added support for SRU scan for ZOOM.
104 Added support for the use of the older versions or Extended Service
105 Update in ZOOM. To faciliate this, an option "updateVersion" may be
106 set to the version , 1=first, 2=second, 3=third. The third version is
107 what ZOOM C has used so far. And that, obviously, is the default.
109 Added support for CCL queries in Z39.50 queries sent to the GFS (and
110 therefore in Zebra and in SimpleServer-based applications). The new
111 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
112 qualifier file used to transform incoming CCL queries into Type-1 RPN,
113 which is passed into the back-end search callback function.
115 Added support for HTTP Basic authentication in clients: the SRU/W
116 codec encodes the username/password elements of the PDU structure
117 appropriately, and these may be set using the "user" and "password"
118 options in ZOOM-C applications (the same options that are used for
119 Z39.50 authentication).
123 Fixed bug #1208: SSL appears to be broken in ZOOM.
125 Fixed bug #1206: Libxml2 include path weirdness.
127 Added oid_name_to_dotstring.
129 Allow elementSetName to be specified for ZOOM C record update.
131 Allow waitAction to be specified for ZOOM C based for Extended Services.
133 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
134 syntax OID. Bug introduced in YAZ 3 series.
136 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
140 Fixed bug #1157: yaz-client does not read .yazclientrc from current
141 directory. yaz-client now reads commands from file given by option -f
142 if specified; then tries to read .yazclientrc in current directory.
143 Failing that, it reads .yazclientrc from user's home directory.
145 Added support for correlationInfo Note and ID for Record Update via
148 Added yaz-client command querycharset which specifies character set for
149 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
150 (termListAndStartPoint).
152 Charset ISO5428:1984 is an alias for ISO5428-1984.
154 Implemented a way to perform scan in a result set using Z39.50. This
155 is achieved by attaching the result set name in the characterInfo
156 (type InternationalString) of OtherInformation in the Scan Request PDU.
157 The result set is identified in the otherinformation by the new OID:
158 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
159 This allows for scan in result set and faceted search . Zebra did some
160 of this in the APT term using attribute type 8 and value being result
161 set. Using the OtherInformation approach for this is cleaner and easier
162 to work with in proxies and the like. This facility can be used in
163 yaz-client using new command setscan which takes a result set as first
164 argument, start position (APT) as second.
166 Changed decoding of SRU XML packed records to deal with servers that
167 have recordData with XML data with multiple root nodes. Also make
168 comparison for recordPacking case insensitive. Again, one server
169 returns "XML" where others return "xml".
171 For SRU responses allow Content-Type application/xml as well as text/xml.
175 Fixed bug in character set conversion of BER strings. Bug introduced
180 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
182 For OID class, use oid_class consistently.
184 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
187 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
188 character set for bibliographic information interchange". By Giannis Kosmas.
190 Added documentation on new OID API.
194 Changes to generic frontend server interface: added new member
195 'query_charset' for bend_initrequest structure. A backend init handler
196 should set this member to its native character set for query terms.
197 When defined, the frontend server logic will announce this character set
198 to a client if the negotiationModel bit is set by the client. All server
199 implementors are encouraged to specify this. If a backend server does not
200 specify this a warning is issued using yaz_log(YLOG_WARN,..).
202 Added CCL utility to remove terms (stop words) from resulting RPN
203 tree. This is handled by functions with prefix ccl_stop_words_ .
205 New ZOOM C option, "rpnCharset", which allows client-side conversion of
206 terms in RPN queries.
208 Clean-up the CCL API. Moved some internal structures from ccl.h to
209 private header cclp.h. Changed ccl_parser_create so that a Bibset must
210 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
211 This is replaced by ccl_parser_find_str which takes a string instead.
213 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
214 libyaz.la is the core of YAZ except the generic frontend server and
215 does not depend on POSIX threads anymore. libyaz_server.la is the
216 generic frontend server facilities and uses POSIX thread functionality
217 if available. The libyaz.la no longer depends on POSIX threads because
218 the number of global structures is limited. NMEM no longer re-uses blocks
219 between threads ; it simply free's memory immediately but allocates in
220 "large" chunks as usual. We don't expect any performance penalties
221 because of this. The yaz_log system is still using a global log_level so
222 caution must be taken when modifying it with yaz_log_init_.. +
223 yaz_log_mask_str. This, however, should not cause any trouble because
224 these functions are called during initialization of application code
225 anyway. `yaz-config --libs server` returns libs for server applications;
226 `yaz-config --libs` returns libs for non-server applications.
228 New OID database - with public definitions in oid_db.h. Removed old OID
229 database including the head oid.h and definitions such as enum oid_value
230 and struct oident. The new OID database uses the same string names as
231 before but the 'protocol' is gone. There are now only two representations
232 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
233 converts from string to OID; functions with prefix yaz_oid_to_string
234 converts the other way.
236 Change to emit_term() in CQL-to-PQF query translation: when a term has
237 the /regexp relation modifier, do not process it for leading and
238 trailing "^" and "*", which have quite different meanings in regular
241 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
242 write handlers no longer carries a 'last' parameter. This will make
243 yaz_iconv flush "less" characters. A flush is performed by call to
244 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
246 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
247 removed, because function yaz_query_to_wrbuf does the same.
249 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
250 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
252 Deprecated MARC utility functions removed.
254 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
257 Branch split: YAZ_2_1_55_branch
259 --- 2.1.54 2007/03/16
261 Fix to ZOOM-C so that transparent reconnection is properly handled on
262 connections that are in asynchronous mode.
264 Fixed compilation on OpenBSD 4.0.
266 Large strings in GRS-1 records are now properly displayed in yaz-client.
268 Added character conversion support for "advancegreek"; based on patch from
271 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
272 sequence is met. Before the error was not set so it would be unknown.
274 Adjust yaz-marcdump MARC reader so that it skips until record separator
277 --- 2.1.52 2007/03/07
279 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
280 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
281 fd_set structure used as a bitmask for the FDs to be selected on.
283 Using ACX_PTHREAD macro to check for POSIX threads.
285 Fixed have-vsnprintf check.
287 --- 2.1.50 2007/02/23
289 Fixes for configure on BSD. Bug #900.
291 Added snprintf/vsnprintf wrappers for systems that don't have
292 limits (heavens forbid).
294 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
295 created before all previous tasks were completed and removed from the
296 task queue, the new task could be removed by a mistake.
298 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
300 Implemented pass-through CQL-to-PQF conversions. Bug #861.
302 Fixed bug #832: Problem with MARC/charset in yaz-client.
304 Fixed bug #668: save command line history for yaz-client.
306 Fixed bug #830: pkg-config support.
308 --- 2.1.48 2007/01/23
310 Extended ZOOM result set options with two options that may be read by
311 a client: resultSetStatus and presentStatus with values as specified for
313 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
315 Fixed bug #827: Using SSL fails on Debian etch.
317 Fixed bug #826: Weird looking chars for set of MARC records.
319 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
320 that is treated as an ItemOrder with itemRequest being an XML document
321 external. The value of "doc" is the content.
323 Extended the GFS search facility. New member of bend_search_rr
324 'estimated_hit_count' signals that hits is known to be an estmate
325 (higher or lower than real hit count). New member 'partial_resultset'
326 signals that the search was partial (hit count is lower or equal than
327 real hit count). For Z39.50, the information is stored in resultSetStatus
328 member of SearchResponse APDU. For SRU, the information is signalled
329 via SRU diagnostic 59: "Result set created with valid partial results
332 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
334 --- 2.1.46 2007/01/13
336 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
338 Added ZOOM_connection_peek_event.
340 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
341 the following new functions:
342 ZOOM_event_nonblock, ZOOM_connection_process,
343 ZOOM_connection_get_{socket,mask,timeout},
344 ZOOM_connection_fire_event_{timeout,socket}.
345 The existing blocking event handler, ZOOM_event, is a wrapper for the
346 + blocking ZOOM_event_sys_{poll,select}.
348 Implemented function ccl_xml_config which parses XML version of CCL
349 configuration (bug #798).
351 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
353 Added timings utility (yaz/timing.h)
355 --- 2.1.44 2007/01/03
357 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
360 Fixed bug #779: Rotation of apdu.log fails.
362 Fixed for character set conversions:
363 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
364 Honor G1 set in MARC-8 decoding.
366 --- 2.1.42 2006/12/17
368 Fixed bug #775: char conversion does not handle Alternative UTF-8
371 Implemented function yaz_marc_read_line which parses MARC line format
372 records. There is a wealth of formats out there. So far, this function
373 reads line records produced by yaz_marc_write_line.
375 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
376 more generic and easier to remember(!) options: -i format and -o format
377 which specifies input format and output format respectively - where
378 format is one of "marc", "marcxml", "line", "marcxchange".
380 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
381 does not print anything except warnings for records.
383 For yaz-marcdump, added support for MARC split into files (-s) with a given
386 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
387 spec, at http://www.loc.gov/standards/sru/record-update/
388 This has changed the binary layout of the following structs:
389 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
390 bend_update_rr . Patch by Ko van der Sloot.
392 Added GFS utility function bend_assoc_is_alive which returns 1 if
393 association is still alive (client is connected); 0 otherwise (client
394 closed connection). This allows busy servers to stop working for
397 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
398 been a separate piece of software. This version of ziffy has been modified
399 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
401 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
403 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
404 Client code may now interrogate options such as "init_opt_sort" to
405 find out whether the server claims to support various options.
407 --- 2.1.40 2006/11/27
409 Added utilities yaz_{set,get}_esn to set/get element set name from
412 Removed the build of libyazthread.la. The libyaz.so is the threaded version
413 of YAZ and has been so since YAZ 2.1.10.
415 Implemented ZOOM_record_error which returns error information for
416 record (surrogate diagnostic).
418 --- 2.1.38 2006/10/31
420 Updates for SRU Update by Ko van der Sloot:
421 1. Changed name from "operation" to "action"
422 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
423 versions in the code, marked as 'backward compatible'.
424 3. Added diagnostics for SRU Update.
426 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
428 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
430 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
432 For GFS, fixed problem with SRU diagnostic 'First record position out of
433 range' being issued for 0 hits.
435 zoomtst10 part of Windows Build.
437 --- 2.1.36 2006/10/13
439 Implemented yaz_filepath_comp which splits a path into file path
440 components (required by Zebra 2.0.3+).
442 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
443 BSD inspired license until now so this should not have any real impact on
444 anybody. See http://www.opensource.org/licenses/bsd-license.php
446 Fixed bug #687: Missing log lines.
448 Fixed bug #678: CQL to PQF translation does not preserve double-quote
451 Fixed bug #689: SRU diagnostics to be added.
453 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
454 whether a connection is idle (no more work do do).
456 --- 2.1.34 2006/10/04
458 Change type of optval from long to int for invocation of setsockopt with
459 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
461 Added support for specifying the max log file size for the Generic
462 Frontend Server. The size is given with option -r.
464 --- 2.1.32 2006/09/21
466 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
468 --- 2.1.30 2006/09/17
470 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
473 Fixed bug in Generic Frontend Server that could cause a server to stop
474 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
476 For the generic frontend server, the maximum record size is used as maximum
477 size of incoming packages (SRU + Z39.50). The value until was previously
478 only used in Z39.50 Init negotiation and, later, in a session controlled
479 sizes of records returned. This is controlled using -k option. It can be
480 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
482 --- 2.1.28 2006/09/04
484 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
487 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
489 New option for yaz-marcdump -lpos=value which allows setting a portion
490 of MARC header to a certain value.
492 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
494 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
495 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
497 --- 2.1.26 2006/08/15
499 Fixed problem with SRU mode type (soap, get, post) for yaz-client
502 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
504 --- 2.1.24 2006/08/08
506 Fixed MARC ISO2709 encoding routines to deal with character set
509 Minor changes to GFS logging. Database included in search request log
512 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
513 cached/multiple records.
515 Shared libraries are built by default on Unix+configure.
517 Changed cql2pqf transformation to use a different evaluation order. The
518 new order is: always, relation, structure, position, truncation, index
519 and relationModifier. Old order was: always, relation, relationModifier,
520 structure, index, position, truncation. Note that the the latter ones
521 override former ones for identical attributes.. The new scheme means that
522 it is possible to override any existing attribute with a relationModifier.
523 And also that it is possible to override everything for the index rule
524 (except the ones listed in relationModifier). No order is perfect but this
525 one, we believe, covers more real cases.. The "always" should have been
526 called "default", since the attributes there can be overridden with all
529 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
530 compilation phase, but also for yaz-config --cflags output. This allows
531 us to have public headers with Libxml2 stuff in them . It should also,
532 eventually, make Libxml2 checks redundant in packages using YAZ, such
535 --- 2.1.22 2006/06/15
537 Changed SRU update structure bend_update_rr so that SRU diagnostics are
538 stored in uri, message and details.. Previously diagnostics were stored
539 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
540 compatibility.. but he's probably the only one affected, so.
542 Added support for CCL, compiled on the client side, in ZOOM-C. This
543 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
544 input; the resulting query objects can be used for for searching with
545 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
547 YAZ' configure searches for OpenSSL by default.
549 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
550 SL_CTX_use_certificate_file. See
551 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
552 for more info. Thanks to Ko van der Sloot.
554 --- 2.1.20 2006/06/02
556 Bug #600: SRU GET, POST support for yaz-client. Introduced
557 command 'sru' which selects method SOAP/GET/POST.
559 Allow missingValueAction to be specified for the sortspec string -
560 function yaz_sort_spec. By default, the missing value action is null.
561 Use ! to specify "abort". Use = followed by stringvalue to specify default
564 Ensured that Present-handler (if defined) is called in GFS before any call to
565 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
566 searchRetrieve requests.
568 Documentation for YAZ is now based on the Docbook XML/XSLT using
569 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
570 is no longer depending on jade/openjade or docbook-to-man scripts.
571 PDF is no longer part of the distribution - but can optionally be
572 made using DSSSL/jadetex or FOP.
574 Added retrieval handling support in Generic Frontend Server to support
575 conversion between MARC/XML as well as XSLTtransforms. See
576 etc/yazgfs.xml for an example.
578 Added Authentication support to Generic Frontend Server in SRU
579 mode. Authentication using HTTP Basic is supported, as is the use
580 of 'x-username' and 'x-password' parameters in the request itself.
582 Added support for a new character set MARC8s identical to MARC8 except
583 that it converts combined characters to single Unicode characters in the
584 Latin-1 range (when possible).
586 --- 2.1.18 2006/04/24
588 ASN.1 compiler 0.4: generates brief Doxygen file header for
589 generated .h/.c files.
591 Utility yaz_iconv now supports conversion to MARC-8.
593 New facilities for the MARC module. The reading - and writing of
594 content are separate methods for the yaz_marc_t handle. The following
595 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
596 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
597 format). Write functions have prefix yaz_marc_write_.. The existing
598 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
599 available. Removed support for OAI-MARC and simplexml (not the
600 simplexml from PHP5).
602 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
603 to be returned for this connection.
605 --- 2.1.16 2006/03/31
607 Allow multiple languages and charsets to be specified with
608 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
609 negcharset iso-8859-1,utf-8
611 Translation of proximity nodes from CQL into PQF now works.
613 Moved to automake 1.8, 1.9.
615 Added function yaz_log_set_handler which allows a log handler to be
616 installed. This handler will be called for all log messages. Output
617 to file is also produced; but that can be disabled by passing NULL
618 fname to yaz_log_init_file.
620 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
622 For SRW (including GFS), accept application/soap+xml as content-type
625 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
626 produces NO stylesheet reference even if a default stylesheet is specified
629 --- 2.1.14 2006/03/14
631 Updated Windows package to include yazd.dll + yazd.lib for the
632 Development component.
634 If the environment variable YAZ_LOG is set, then it is used as a
635 string indicating the default level of logging to use if not
636 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
637 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
638 used as before. So, for example, to omit warnings from YAZ logging,
641 cql_transform() now map structure and other attributes before indexes,
642 so that index-specific structures and other attributes can override
643 defaults. So now a combination of mapping specifications such as:
645 index.dc.date = 1=date-modified 4=5
646 does the right thing.
648 cql_transform() now also respects the "always" mapping specification,
649 which establishes an initial set of attributes to be used for all
650 terms except where overridden by more specific attributes associated
651 with the index, relation or modifier.
653 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
654 which mode to use; one of "post", "get" or "soap" (SRW, default).
656 Fixes for yaz_iconv routines: changed trie-based character set conversions
657 to use only non-negative values for bit fields due to Sun's C compiler not
658 supporting negative values.
660 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
661 sequences where not read correctly. Fix by Rustam Usmanov.
663 Updated win/makefile to use options, settings which makes things
664 compile with VS C 2005.
666 --- 2.1.12 2006/02/01
668 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
670 In ZOOM socket code, use select instead of poll on MacOSX.
672 ZOOM-C now support client-side compilation of CQL into RPN that is
673 sent to the server, enabling CQL to be used against all Z39.50
674 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
675 ZOOM_query object, and submit it using ZOOM_connection_search().
676 The CQL-to-RPN translation uses a configuration file, the name of
677 which must be specified in the Connection's "cqlfile" option.
679 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
680 function, which takes as its start-term parameter a ZOOM_query object
681 (which may have had either CQL or RPN set into it).
684 --- 2.1.10 2005/11/29
686 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
687 GFS to support this as well. Backend handler, bend_srw_update, does the
688 update work. Code contributed by Ko van der Sloot.
690 Allow retrieval of Search Result-1 information in ZOOM by the use of
691 options that are attached to a result set. ZOOM documentation updated
694 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
695 UTF-8 conversion. Patch by Raj Patel.
697 Added option -m to GFS to control formatting of timestamps in log file.
699 Added 'exit' as synonym for 'quit' in yaz-client
701 Added support for specifying SRW resultSetId + resultSetIdleTime in a
702 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
703 for the new members. Patch by Ko van der Sloot.
705 Added support for SRU POST. It is supported for content-type
706 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
708 Do not build the separate Multi-threaded (MT) library libyazthread.la.
709 Instead make the library libyaz.la multi-threaded. Threading as a whole
710 can still be disabled by configure option --disable-threads. Previosly,
711 with older GLIBCs there were problems with MT libs under Apache. This
712 has now been fixed a long time ago.
714 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
717 CQL module modified to be case insensitive for relations/indexes/operations.
719 Fixed bug in CQL transform code: incorrect value relationModifieder
722 Added 'show all' command for yaz-client which retrieves all results
725 Added new yaz-client, xmles, which takes a (private) OID and
726 a document to be sent as an extended service request.
728 Describe new yaz-client commands wait_response and set_auto_wait.
730 Increase TCP/IP listener backlog from 3 (which I am guessing was
731 copied from the SunOS manual entry way back when) so SOMAXCONN, so
732 that the socket will queue as many incoming connections as it's able
733 to handle ongoing connections. In other words, it will never now
734 refuse a connection that it would be able to handle merely because
735 it's not got around to accepting() enough of the pending connections
736 yet. This is the behaviour anyway under Linux, where the listen()
737 argument is ignored; but not under BSD and on systems such as
738 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
739 YAZ-based servers should now be uniform across operating systems in
742 yaz-marcdump uses 64-bit file access on some systems. This is enabled
743 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
744 This allows yaz-marcdump to read large MARC batches (>2 GB).
746 Modified all YAZ source files - except the source which is auto-generated
747 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
750 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
751 corresponding to the existing *_setl() function. These allow option
752 values containing arbitrary valuues.
754 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
755 ZOOM_resultset_sort() in new applications. Its behaviour is identical
756 except that it returns an indicator of whether or not the sort
757 criterion was accepted (0 for OK, -1 for invalid).
761 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
762 MARC output rather than returning "new" buffer.
764 yaz-client warns about unknown init options.
766 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
770 Added support for SRW sort in Generic Frontend Server. Patch
771 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
772 sortKeys - or NULL if none is provided.
774 Fixed bug #307: It was impossible to specify indefinite/no timeout
775 for ZOOM_event. Special timeout value -1 now means indefinite timeout
778 Added support for multiple languages and charsets to be specified in
779 ZOOM. Each charset/language is separated by a blank. If negotiation is
780 in effect in init-response, Option
781 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
782 Code based on patch by Vasiliy Osadchuk.
784 Fixed bug #306: infinite recursion that occurred when calling
785 yaz_log_level_init as the first call (before other log level or
788 Fixed bug in scan handling in front end server: if preferred-Position-In-
789 Response was non-present, a NULL pointer referece was performed.
793 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
794 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
795 now defined for all those error codes. So instead of putting 109 in
796 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
797 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
799 Modified the yaz-marcdump utility to skip garbage bytes between MARC
802 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
804 Program yaz-client now exits and produces an error message if multiple
805 Z39.50 servers are specified on the command line (none or one allowed
808 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
813 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
815 Fixed bug #272: Preserve spacing for CCL terms.
819 Added support for virtual hosts and multiple backend servers for
820 the YAZ frontend server. The configution is XML based and
821 support specificition of CQL to RPN mappings and explain information.
822 See section "Virtual Hosts" in the YAZ manual.
824 Extended OPAC display utility. OPAC display utility renders
825 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
826 to supplement yaz_marc_decode_wrbuf.
828 Fixed a bug in MARC decoder that could caused it to crash for some
829 invalid MARC records. More diagnostics and warnings where added in
830 XML output (warnings, etc are stored in comments).
832 --- 2.0.34 2005/02/08
834 Fixes for UNIX domain sockets. Bug #261.
836 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
838 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
839 Added yaz_marc_subfield_str which defines subfield lead string which is
840 used in YAZ_MARC_LINE format. Default string is blank+$. Added
841 yaz_marc_endline_str which defines end of fields string used in
842 YAZ_MARC_LINE format. Default string is newline.
844 Experimental support for MarcXChange. This format can be produced
845 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
846 http://www.bs.dk/standards/MarcXchange.xsd
848 Added yaz-client commands scansize that sets maximum number of
849 entries to be returned by scan.
851 --- 2.0.32 2005/01/11
853 Added support for SRW scan in yaz-client and Generic Frontend Server.
855 * Added whereInList member to SRW Scan Term.
857 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
859 Fixed NMEM system to return aligned blocks on the smallest boundaries
860 that are suitably aligned for all possible types on the particular
861 architecture YAZ is being built for.
863 --- 2.0.30 2005/01/04
865 Fixed numerious warnings that was issued with newer versions of GCC.
867 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
868 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
871 Make YAZ Generic Frontend Server slightly faster.
873 Enhance (and reduce) logging for Generic Frontend Server.
875 Revert YAZ log system so that it flushes every write operation
876 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
878 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
879 instead of LOG_, due to name clash with syslog(3). LOG_ are still
880 present. New applications should define YAZ_USE_NEW_LOG=1 - this
881 will effectively disable old definitions.
883 --- 2.0.28 2004/11/09
885 Added yaz_log_time_format which specifies log format using
888 Added yaz_log_module_level which returns mask for a module. Value
889 is non-zero mask a if module is enabled; zero if disabled.
891 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
892 in include/yaz/cql.h.
894 Fixed bug #176: Dont throw diagnostics on empty SRU args.
896 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
898 Fixed bug #172: RPM builds does not enable SSL.
900 Doxyfile.in part of dist. Doxyfile generated by configure.
902 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
903 are given and the corresponding component does not exist.
905 Extend CCL documentation in YAZ reference. Describe r=r.
907 --- 2.0.26 2004/10/01
909 Fixed MARC->MARCXML conversion to properly deal with
910 fields, subfields, indicators having non-ASCII characters.
912 Fixed MARC->MARCXML conversion so that ASCII control characters
913 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
916 Added YAZ GFS support for conversion from Z39.50 surrogate
917 diagnostics to SRW surrogate diagnostics.
919 Bug fix: YAZ GFS did not return schema in explainResponse.
921 --- 2.0.25 2004/09/30
923 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
924 now converts recordSchema to elementSetName as well as schema URI.
926 Fixed bug in COMSTACK that prevented HTTP request packages from being
929 --- 2.0.24 2004/09/29
931 Added CCL facility r=r "range" which is similar to r=o "ordered" but
932 does not require white-space before and after the dash in a range, e.g.
933 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
936 Fixed a few AC_TRY_LINK configure tests that did not operate properly
937 due to new GCC removing "redundant" code.
939 Added yaz-client commands scanpos and scanstep that sets preferred
940 position and step-size for scan.
942 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
944 Added CCL utility ccl_qual_buf which parses one or more CCL
945 spec lines in a buffer.
947 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
948 of name and value - ignoring empty lines and comments.
950 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
952 Added odr_get_element_path which returns current element path for an
953 ODR handle. This utility is useful in error handling or user-defined
956 Added ODR_PRINT utility odr_set_stream which is is a more generic
957 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
958 to a write function and pointer to close function. The close function - if
959 non-NULL - will be called during odr_destroy.
961 Fixed bug in CCL parser where truncation char was not removed from
962 right side when truncation=both was in effect.
964 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
967 --- 2.0.23 2004/08/11
969 Fix buffer overrun in CQL parser when dealing with proximity (%).
971 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
972 to UTF-8/UCS conversion is now only based on codetables.xml.
974 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
976 --- 2.0.22 2004/08/06
978 Add support for more "commit changes" in ZOOM (uses Extended Services).
980 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
983 Yet another small fix for configure of SSL.
985 --- 2.0.21 2004/05/14
987 Fix SSL libs for configure when --with-openssl=DIR is given.
989 --- 2.0.20 2004/05/10
991 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
993 SSL comstack now uses yaz.pem certificate file on server side
994 by default. Certificate filename can be configured by calling
995 comstack function cs_set_ssl_certificate_file before cs_bind is used.
997 Fix bug regarding multiple calls to ZOOM_connection_connect.
999 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1001 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1002 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1004 ZOOM now allows inspection of X509 peer certificate for verification.
1005 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1007 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1008 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1009 as "modular" but it simplifies things.
1011 Added cs_get_peer_certificate to that returns peer X509 PEM.
1013 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1014 NULL if SSL is unavailable.
1016 Documentation about MARC decoding tools.
1018 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1020 --- 2.0.19 2004/03/30
1022 Rename CHANGELOG to NEWS to follow GNU style packing.
1024 Fix bug with missing initialization of member in init_diagnostics.
1025 This bug affects threaded version of GFS server.
1027 --- 2.0.18 2004/03/20
1029 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1032 Ensure zlib.dll is packed with Windows install.
1034 --- 2.0.17 2004/03/17
1036 Fix encoding of xsd:string to use text instead of CDATA.
1038 Fix endless loop in CQL parser with unbalanced ".
1040 Use a more compact way to store MARC-8 conversion tables.
1042 --- 2.0.16 2004/03/16 Debian only
1044 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1047 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1052 --- 2.0.15 2004/03/01
1054 Another fix for decoding of XML packed records.
1056 --- 2.0.14 2004/02/25
1058 Fixes for Chunked encoding. White space not ignored after length spec.
1060 Update NS and use default NS for SRW diagnostic elements.
1062 --- 2.0.13 2004/02/23
1064 Implement ZOOM_resultset_cache_reset which resets record cache.
1066 Implement ZOOM_resultset_sort which sorts a result set.
1068 Implement chunked HTTP transfer.
1070 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1072 --- 2.0.12 2004/02/16
1074 Added member 'schema' to bend_explain_rr structure so that backend
1075 can specify explain record identifier. Defaults to Zeerex 2.0.
1077 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1079 --- 2.0.11 2004/02/16
1081 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1084 Added init command for yaz-client which sends "extra" init request.
1086 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1087 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1089 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1091 Make ZOOM error code for "invalid query".
1093 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1095 --- 2.0.10 2004/02/05
1097 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1100 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1102 Added option -p <file> to make Generic Frontend Server to write PID file.
1104 Added option -D to put Generic Frontend Server in background on its own.
1106 Make ZOOM C recognize option "password". If unset, "pass" is used
1107 (for backwards compatibility).
1109 Fixed a bug in Generic Frontend Server that could make it crash if a
1110 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1113 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1114 Must be issued before open, in order to be in effect.
1116 --- 2.0.9-6 2004/01/12 Debian/Windows
1118 Make the SRU server more picky WRT unknown params, etc.
1120 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1122 New YAZ client command, options, that sets Z39.50 options.
1124 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1125 options from a string of tokens (one token for each option bit).
1127 Update SRW diagnostic code messages.
1129 --- 2.0.9-5 2004/01/07 Debian/Windows
1131 Handle user defined stylesheet for SRW/SRU.
1133 --- 2.0.9-4 2004/01/06 Debian/Windows
1135 Fix bug in decoding of Content-Length.
1137 --- 2.0.9-3 2004/01/06 Debian/Windows
1139 Fix a bug with decoding of XML packed records.
1141 --- 2.0.9-2 2004/01/05 Debian only
1143 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1145 Fix bug in SRW/SRU diagnostics decoding.
1147 --- 2.0.9 2004/01/05
1149 Fixed bug in Generic Frontend Server which could drop records exceeding
1150 preferred message size. Reported and fixed by Irina Dijour.
1152 Fixed calculation of package size for structured records in Generic
1153 Frontend Server. Reported and fixed by Irina Dijour.
1155 Fixed namespace for SRW/SRU diagnostics.
1157 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1159 --- 2.0.8 2003/12/22
1161 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1162 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1165 CQL changes to reflect recent changes to the specification:
1166 * Documentation talks about context sets instead of index sets.
1167 * Documentation talks about indexes instead of qualifiers.
1168 * The CQL-to-PQF transformer's configuration file now uses
1169 "index.set.name = <attributes>" instead of the old form
1170 "qualifier.set.name = <attributes>". (Both forms are still
1171 understood but the latter is deprecated.)
1172 * CQL terms with no explicit index specified are now interpreted as
1173 cql.serverChoice instead of srw.serverChoice (which of course
1174 behaves exactly the same.)
1176 --- 2.0.7 2003/12/16
1178 MARC conversion can now generate ISO2709 output in another
1179 character set. yaz-marcdump uses this facility if you invoke it
1182 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1183 functions from there can be used from C++.
1185 --- 2.0.6 2003/12/04
1187 Frontend server now transfers memory from decoded packages to stream
1190 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1191 references to show up.
1193 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1194 the ZOOM Abstract API. The older names for the same options are still
1195 also supported for the benefit of old applications.
1197 ZOOM-C supports "implementationId" and "implementationVersion" options
1198 to go along with "implementationName". These allow the user code to
1199 specify identification strings to be sent to servers.
1200 Add OID for the new ExtLite attribute set.
1202 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1203 as requested/supplid by Ere Maijala <ere@atp.fi>
1205 For generic frontend server, reverse the order of
1206 "toolkit-supplied / application-supplied" strings sent as implementationId,
1207 Name and Version. Also, remove the spaces around the slash. This brings
1208 the GFS in line with the behaviour of ZOOM-C on the client side.
1210 Add function ZOOM_scanset_display_term.
1212 yaz-client shows scan displayTerm if present.
1214 Utility yaz-iconv is now installed by default along with the man page
1217 Extend configure check for OpenSSL to use pkg-config where available (such
1220 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1221 server to specify uid/gid/mask for socket using the format
1222 unix:[user=uid,][group=gid,][umask=mask,]file=path
1223 If file= is omitted the existing format is assumed, e.g.
1225 in which case the mask is 0666 (rw for everybody).
1227 Major restructure of YAZ source. All source in libyaz is in src directory.
1228 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1229 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1231 Added man page for utility yaz-marcdump (used to be called marcdump).
1232 yaz-marcdump is installed by 'make install'.
1234 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1235 of incoming package failed.
1237 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1239 Change prototype of odr_perror: add const to message string.
1241 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1243 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1244 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1245 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1246 DNS lookup. There should not be any compatibility problems with this
1247 assuming that blocking=1 or 0 is used.
1249 Fix bad reference in UNIX comstack in function cs_addrstr.
1251 Fix for compilation on AIX.
1253 The generic front-end server (server/seshigh.c) now supports returning
1254 Init diagnostics to the client in User-information-field, in
1255 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1258 --- 2.0.4 2003/09/04
1260 Allow any CQL relation (not just all,any,exact,scr).
1262 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1263 that features the same UI.
1265 Implemented command update0 in YAZ client which is equivalent to
1266 update but uses old of Ext Update ASN.1.
1268 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1269 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1270 Previously no OID was used for this info.
1272 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1273 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1274 returns 'malformed search term' otherwise.
1276 SortResponse member resultCount now set to NULL in sort handler of
1279 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1282 Add three new utility functions for translating OIDs between various
1283 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1284 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1285 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1286 char *oid_to_dotstring(const int *oid, char *oidbuf);
1287 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1289 Reverted modifications for ES Update definition for z_IU0Update
1290 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1291 is back to YAZ 2.0.2.
1293 String value attributes for CCL parser.
1295 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1296 which their FirstSearch server returns in Init responses, sometimes
1297 carrying useful diagnostic information when Init fails. This has the
1298 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1299 "z39.50/oclcui.asn", where its definition is somewhat different from
1300 what OCLC document on their web-site, as required to interoperate with
1303 Support for anonymous authentication in yaz-client. Use the command
1306 * Fix the OID of the Index Data-local "admin" Extended Service from
1307 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1308 the 1000, which indicates a locally-defined OID, was a mistake.
1310 --- 2.0.3 2003/06/20
1312 Fix CCL directive @case handling so that it affects string match for
1313 both CCL keywords and qualifiers.
1315 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1316 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1317 Decoder has been updated with ASN.1 changes as listed in
1318 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1319 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1320 z_IUUpdate, remains unchanged.
1322 ZOOM_record_get may now return a record in a specific character set.
1323 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1324 "from" is the character set of record as returned by target. "to" is
1325 the character set to be returned. If omitted, "to" is UTF-8.
1327 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1329 New ODR utility, odr_getelement, which returns name of element for
1330 which encoding/decoding failed.
1332 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1333 in cases where a required element was omitted.
1335 Bug fix: some MARC8 sequences were not converted.
1337 New ZOOM option "step" which specifies number of records to be
1338 retrieved in one chunk. Used in conjunction with "start" and "count".
1340 SRW support for yaz-client. Use scheme http: to use it, e.g.
1343 yaz-client no longer does (un)intelligent character set conversions
1344 by default. Can be enabled with charset and marc_charset commands.
1346 xmalloc trace fix for 64-bit systems such as DEC alpha.
1348 Solaris 2.6 compile fix.
1350 New function, cql_strerror() translates SRW error codes, as returned
1351 by cql_transform_error(), into human-readable English strings. Used
1352 in yaz-client diagnostics when appropriate.
1354 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1355 converts it into a type-1 query which is sent to the server. This
1356 makes CQL available for use with all Z-servers, as opposed to the tiny
1357 minority that can handle CQL queries themselves.
1359 --- 2.0.2 2003/04/28
1361 New Debian package layout similar to the Redhat Package layout.
1363 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1364 and search result respectively.
1366 --- 2.0.1 2003/04/25
1368 Redhat package is now several packages: libyaz (runtime libraries),
1369 libyaz-devel (development and documentation, and yaz (utility programs).
1370 Package spec file by Morten Bøgeskov.
1372 New member 'schema' in struct bend_fetch_rr which the name of requested
1373 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1374 handler MAY set this to reflect the schema of the returned record.
1376 New member 'display_term' in struct scan_entry. GFS now sets member entries
1377 and allocates scan entries to be filled by user scan handler. In previous
1378 version, entries member was allocated by the scan handler. That still works,
1379 but the GFS will ignore member display_term - assuming it was NOT set by
1380 the handler. The fact that the GFS now allocates the entries both allows
1381 for new members and makes a scan handler easier to write.
1383 Fix CQL lex buffer overflow.
1385 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1386 SRU default recordPacking is string.
1388 SRU protocol support for frontend server.
1390 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1392 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1394 Added scan for the ZOOM shell (zoomsh).
1398 * String Identifers for Schemas (Amendment 5).
1399 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1400 Old definition for schema
1401 Odr_oid *schema; /* OPT */
1406 Z_InternationalString *uri;
1407 #define Z_Schema_oid 1
1408 #define Z_Schema_uri 2
1411 * resultCount parameter to Sort Response (Amendment 1).
1412 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1414 Support for SRW 1.0 over HTTP. This is an optional feature and
1415 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1418 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1419 on the same port. SRW SearchRetrieveRequests are mapped
1420 to bend_init,bend_search,bend_fetch,bend_close.
1422 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1424 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1425 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1427 ZOOM connections are SRW based if schem http is used for hostname
1428 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1429 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1431 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1432 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1433 distance=n, order=true/false, relation=le, prox unit=word. If
1434 n is omitted, distance 1 is used.
1436 Fixed problem with C compiler include path in wrong order.
1438 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1439 on Solaris. Patch from Ko van der Sloot.
1441 New MARC decode API. All new functions operate on a yaz_marc_t
1442 handle. The most important new functions are: yaz_marc_create,
1443 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1444 decode and destroy respectively. Decoder can produce formats
1445 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1446 include/yaz/marcdisp.h.
1448 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1449 to UTF-8, UCS-32, wchar_t or Latin-1.
1451 * Prototypes for yaz_iconv_-functions moved to separate header
1452 include/yaz/yaz-iconv.h.
1454 Make a few private functions 'static' in unix.c. This prevents
1455 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1457 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1458 are set when Init Response is received.
1460 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1461 but returns diagnostic set as well.
1463 New function yaz_strerror which is a portable wrapper for
1464 strerror/strerror_r/GetLastMessage.
1466 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1467 is returned for MARC. If type is "oai", then OAI MARC is returned.
1469 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1472 --- 1.9.2 2002/11/26
1474 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1476 Fix bad race conditions on SIGTERM and terminate gracefully in
1479 Move retrieval (data1) module to Zebra since nobody seems to be
1482 Add GRS-1 render for ZOOM using same format as yaz-client.
1484 --- 1.9.1 2002/10/05
1486 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1488 Fix broken ESpec handling in data1 module.
1490 SGML reader parses comments and makes them part of the data1 tree.
1492 Added several type casts so that YAZ compiles as C++ code.
1494 ZOOM didn't handle PDU encoding failures properly.
1496 Added more Bib-1 diagnostics (approved extensions).
1498 GNU configure: better check for iconv.
1500 More portable use of accept, getpeername. Check for socklen_t. Use
1501 int/size_t if socklen_t is not defined.
1505 PQF parser rejects bad queries - including those with extra
1506 characters in them. PQF parser used to silently ignore that.
1507 Cleaner API for PQF added, which allows you to get detailed
1508 error information for bad queries (see yaz/pquery.h).
1510 Fixed bug in ZOOM_record_get for type "database".
1512 Implemented mini iconv library supporting conversions between
1513 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1515 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1517 --- 1.8.9 2002/08/20
1519 Fixed ZOOM C record cache so that preferredRecordSyntax and
1520 elementSetName is used to check for already fetched records.
1522 --- 1.8.8 2002/08/02
1524 Added three members in bend_initrequest structure to facilitate
1525 character set negotiation.
1527 Fixed a bug in frontend server that could cause indefinite
1528 loops under rare conditions.
1530 Revised character set utilities (charneg.h) so that encoding
1531 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1533 For PQF, directive @term <type> sets term type for Scan/Search.
1534 Here <type> is general, string, numeric, null. The term type
1535 is inherited - just like @attr.
1537 New call odr_set_charset that sets character set conversion for
1538 international-strings on a ODR stream. Prototype is:
1539 int odr_set_charset(ODR o, const char *to, const char *from);
1540 The InternationalString is still represented as C string in YAZ
1541 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1542 won't). On the protocol level, you can use any encoding.
1544 Support for UNIX sockets in ZOOM.
1546 Solaris recv sometimes returns errno == ENOENT. It is treated as
1547 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1549 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1550 both client and server. Code by Morten Bøgeskov.
1552 --- 1.8.7 2002/05/22
1554 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1555 that they can be used directly from Visual Basic. You must recompile
1556 your windows APP if you're using ZOOM.
1558 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1559 Commands "lang" and "charset" sets language and character set respectively.
1560 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1561 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1563 Attributes from multiple CCL fields may be OR'ed rather than merged
1564 using directive "@field or". Fields are still merged by default -
1565 equivalent to "@field merge".
1567 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1570 Fixed bug in zget for parameter ExtendedServicesResponse.
1574 --- 1.8.6 2002/03/25
1576 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1578 Client displays USR.1:SearchResult-1 (hits per term).
1580 Additional Search Info for search in Generic Frontend Server.
1582 Fixed CCL parsing of "field=s".
1584 WIN32 installer - using the excellent NSIS software from nullsoft.
1586 Fixed CCL parsing of "field = - <number>".
1588 Added function yaz_marc_decode that decodes MARC for line mode
1589 display or XML (similar to that used by JZKit).
1591 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1592 Z39.50. But ISO/ILL was, however.
1594 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1595 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1597 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1598 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1600 --- 1.8.5 2002/02/03
1602 New YAZ client features: Command completion and new commands:
1603 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1604 Code provided by Jacob Poulsen.
1606 New call oid_trav, that visits all registered OIDs via callback.
1608 Function ZOOM_record_get now returns const char pointer rather than
1609 void pointer. It saves a lot of type casts.
1611 For YAZ client, command "auth" now allows you to set authentication
1612 in IdPass style. It is enabled when three tokens are given - order
1613 is user, group and password.
1615 Fix memory leaks in MARC record handling for ZOOM.
1617 New option for YAZ client, -k <kilobytes> that sets
1618 maximum record size. Similar to -k option for generic frontend
1619 server and yaz-ztest.
1621 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1623 Prefix query parser reports "fail" when bad attribute set is given.
1625 Fix in MARC decoder. Proximity logging. Fix for attribute set
1626 in scan handler for server. Patches by Shigeru Ishida.
1628 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1631 Configure option --with-openssl=<dir> now works when a directory is
1632 specified. Patch provided by Morten Bøgeskov.
1634 New option for YAZ client, -u <auth>, that sets authentication.
1636 ZOOM fix: error information was sometimes "missing", since error
1637 was cleared/reset too when it shouldn't.
1639 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1641 --- 1.8.4 2002/01/04
1643 Scan for ZOOM API. New object ZOOM_scanset. New functions
1644 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1645 ZOOM_scanset_destroy.
1647 New ZOOM function, ZOOM_connection_last_event, that returns type
1648 of last event (such as "receive data", "send data", "apdu received",
1651 New ZOOM option, schema, that specifies schema for retrieval.
1653 New CCL feature. Qualifiers can be aliases for one or more
1654 other qualifiers (if more than one is given, OR is used).
1656 ZOOM uses named result sets if target supports it.
1658 Two new YAZ client commands: . (dot, which sources a script of YAZ
1659 client commands), and ! (to execute shell command.). Implemented
1662 Working on Debian packages.
1664 --- 1.8.3 2001/11/19
1666 YAZ client enables named result sets only if target supports it.
1668 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1670 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1671 with key="host" to get same result.
1673 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1674 Function Z3950_resultset_record(s) returns references to records
1675 "owned" by resultset. To become owner use Z3950_record_clone.
1677 Function z_ext_record handles Extended Services. Thanks to
1680 --- 1.8.2 2001/11/12
1682 CCL Parser fix: ignore token comma when dealing with and-lists.
1684 Documentation updates for COMSTACK.
1686 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1687 Changed prototype Z3950_records. For some functions, int parameters
1688 were changed to size_t.
1690 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1693 New MARC decode/display function, marc_display_exl, which properly rejects
1694 non-ISO2709 records. YAZ client uses it.
1696 --- 1.8.1 2001/10/29
1698 Fix bug: local attribute set wasn't set correctly in PQF strings.
1702 * Old Z39.50 codecs no longer supported.
1704 Added ZOOM C binding. See http://zoom.z3950.org/
1706 Renamed states for COMSTACKs to avoid confusion with events.
1708 Implemented cs_look and proper cs_rcvconnect.
1710 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1712 Configure detects POSIX threads on OpenBSD.
1714 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1715 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1717 When error is returned from present handler, non-surrogate diagnostic
1718 is returned in present response (and fetch handler is no longer called).
1720 * Minor adjustments to pquery parser (PQF). Token characters may be
1721 escaped by using backslash (C-style).
1723 PQF parser allows string attribute values to be specified. For @attr,
1724 non-numeric characters after the equal-sign are treated as strings
1725 (e.g. @attr 9=title).
1727 CCL trunction character may be defined (@truncation in file)
1729 * function zget_ExtendedServicesRequest sets waitAction to
1730 waitIfPossible (was wait).
1732 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1735 CCL operator names may be set in field definition files (CCL_bibset).
1736 See ccl/bib1 for an example.
1738 Fixes in ASN.1 compiler for C++ compatibility.
1740 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1741 and "op_or" to avoid conflict with C++.
1743 Fixed problem with GNU readline detection on Redhat 7.0.
1745 Added step-size for Scan backend handler.
1747 Fixed bug that made the frontend server crash when no attribute
1748 set was specified for scan.
1750 Front-end server automatically switches to original working directory
1751 when installed as an NT service. Previously -w had to be specified to
1754 Added extended attributes for retrieval module (data1), so that data1
1755 records carry d1_readXML/SGML attributes. d1_read also supports
1756 null-data rules ( <tag/>)
1758 On UNIX when POSIX threads are available, a separate library libyazthread
1759 is created. Programmers should link with that library and the yaz library
1760 when using threads. The reason for the split was that some applications
1761 on Linux, such as Apache, doesn't work well when using shared objects that
1764 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1765 (or any frontend server) in SSL mode by specifying ssl: followed by
1766 address. Only tested on UNIX.
1768 Added feature for CCL module. Virtual structure s=al or s=ol generates
1769 and-list and or-list respectively instead of phrase search.
1773 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1774 log_mask_str. This was done to avoid name conflicts with other libraries
1775 (such as other PHP extensions).
1777 Added raw OID member for preferred record syntax (request_format_raw)
1778 and returned record syntax (output_format_raw) for backend fetch method.
1780 Config file yaz-config now accepts options so that it returns specific
1781 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1783 Shared library support for UNIX using GNU libtool.
1785 * Modified backend interface. Request/Response struct's replaced by
1786 one read/write C struct. For example bend_fetchrequest and
1787 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1788 Every handler - even search has to be registered in bend_init
1789 handler. This means that the YAZ library no longer refers to
1790 external functions and it makes it possible to make the whole
1791 thing a single DLL/SO.
1793 Added Segment handler for backend server.
1795 Added Zmbol/Zebra administrative functions to YAZ client.
1797 Threaded frontend server on UNIX (when POSIX Threads are available).
1798 Starting the server with option -T enables multi-threading.
1802 Added configure option --enable-comp/disable-comp to control use
1803 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1804 located in sub directory asn.
1806 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1807 in ${exec_prefix}/bin along with the other programs yaz-client and
1810 GNU automake used to maintain makefiles.
1812 Added several OID's.
1814 Changed retrieval module so that we can load records with no abstract
1815 syntax defined. Tagpaths in these records are fully composed of string
1818 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1822 On UNIX, the generated makefile now supports a proper 'make install'.
1823 The prefix can be set via GNU configure to set the install location
1824 (default is /usr/local).
1826 * YAZ programs client and ztest were renamed to yaz-client and
1827 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1828 locations, such as /usr/bin,/usr/local/bin,etc.
1830 * YAZ Header files were moved from include to include/yaz. YAZ Header
1831 files are referred to as include <yaz/log.h> rather than <log.h>.
1832 The YAZ include path (-I ..) is therefore the same as before. Programmers
1833 should update their #include statements or use -Ipath/include/yaz
1834 instead. The main motivation for doing this change is that YAZ header files
1835 can be installed in "standard" locations /usr/include,/usr/local/include
1836 without introducing conflicts, since ALL YAZ header files are stored
1837 in subdirectory yaz (under /usr/include for example).
1839 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1840 rather than project/workspace files. We switched because project files
1841 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1844 Changed name of logging function, logf, to yaz_log, to prevent name
1845 clash with some math-log functions. The YAZ header log.h defines logf
1846 to yaz_log (#define) so there should be no incompatibilities by this
1849 Added bend_start/bend_stop handlers for server. These handler are
1850 called on start/stop of server. For windows they are called whenever
1851 a service is started/stopped.
1853 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1854 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1855 in util/yc.tcl. The auto-generated C code structures are, in a few
1856 cases, incompatible with the old decoders. There are differences in the
1857 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1858 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1859 The preprocessor variable ASN_COMPILED is defined when the compiled
1860 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1861 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1862 wish to use the old encoders/decoders you can specify --disable-yc
1865 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1866 version so that it supports both new - and old version of DB Update
1868 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1869 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1870 change. The name parameter can be set to 0 in which no name is specified
1871 for the construction. The macros odr_implicit and odr_explicit sets name
1872 parameter to zero for the construction involved. New macros
1873 odr_implicit_tag and odr_explicit_tag are similar to the others,
1874 except that a name parameter is added. For programmers' that don't use
1875 ODR they probably only need to change the call to z_APDU and z_External.
1877 Added access control facility by interfacing the TCP wrapper library.
1878 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1879 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1880 name of the daemon and enables the access control as specified in
1881 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1883 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1884 den Dool <H.M.vdnDool@kub.nl>.
1886 Added reference ID parameter to most functions in server API - refer
1887 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1889 Changed name of ccl library to libccl.a (was ccl.a).
1891 Fixed bug in decoder for Explain (Category TargetInfo).
1893 Added support for GNU readline in client. Thanks to Jacob Poulsen
1894 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1896 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1897 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1898 IMPLEMENTATION! This change was made to the development version before
1899 the ZIG decided to retract the amendment. If any users MUST be
1900 compatible with the original Update definition, PLEASE CONTACT US, and
1901 we will include a separate definition corresponding to the old Update
1902 ES. Note that because of the change to the ASN.1 of the
1903 TaskPackageRecordStructure we cannot define a single structure that
1904 will support both versions.
1906 * Added const modifier to buffer parameter for some ODR/BER encoding
1907 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1908 completeWAIS, odr_dumpBER.
1910 Fixed bug in client.c which caused a crash when a scanResponse didn't
1911 contain positionOfTerm.
1913 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1914 * will cause an error in a client if a non-YAZ target sends both a
1915 * list of Scan entries and non-surrogate diagnostics.
1917 Retrieval module enhancements. Tag sets may be typed in the reference
1918 to it. From the .abs-file the "tagset" directive takes a third optional
1919 integer type for the tag set referenced. From a .tag-file the "include"
1920 directive takes a third optional type as well. The old "type" directive
1921 in the tag set itself is still recognized but acts as the default type
1924 Backend interface change. Individual Scan terms returned from bend_scan
1925 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1926 in include/backend.h.
1928 Retrieval module enhancements. Multiple tag sets and attribute sets may
1929 be specified in abstract syntax specs. Revised the error/warning for
1930 logging messages reported by the retrieval module when reading the
1933 Object Identifier system (oid_..) changed. The API is backwards
1934 compatible but the oid-routines now allocates new OID's when needed.
1935 Raw OID's may be specified in oid_getvalbyname.
1937 YAZ now uses GNU configure to generate Makefile(s).
1939 * Minor changes in some of the member names of DeleteResultSetRequest and
1940 DeleteResultSetResponse. See include/proto.h.
1942 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1943 and added member 'languages' in TargetInfo (which was missing).
1945 Changed the way attribute sets are handled in the retrieval
1946 module. These are now cached, just like the abstract syntaxes
1949 Changed YAZ so that it links with compiled ASN.1.
1951 Added Explain-schema definitions and mapping routines. The following
1952 Explain categories have been implemented: AttributeDetails,
1953 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1955 Fixed minor bug in Windows version of Server Library.
1957 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1959 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1961 Added EXTERNAL: UNIverse Resource Report (non-standard).
1963 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1964 ENUMERATED and SET OF.
1966 * Added 'const' to some of the char pointer arguments for the
1967 functions, data1_read_node, data1_getelementbytagname,
1968 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1971 Fixed bug in data1_insert_taggeddata - the last_child member of
1972 parent wasn't initialised.
1974 * Changed data1_read_record and data1_read_node so that the supplied
1975 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1976 doesn't refer to any parts of the "SGML"-buffer.
1978 Fixed bug in server library (Windows version of statserv_remove).
1980 * Changed code so that it compiles as C++. The type definition
1981 of Odr_fun which is a member of Odr_arm was changed. The result is,
1982 that an explicit typecast is needed for the fun pointer when
1983 using Odr_arm - as in:
1984 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1986 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1988 Implemented the new structured date and time definition as approved
1989 by the ZIG. Added schemaId element to the specificTag in Espec-1
1990 (also approved at the last ZIG). Thanks to RVDM.
1992 Added some Object identifiers (RVDM).
1994 Changed the Update Extended Service (RVDM).
1996 Added command "refid" to client which specifies referenceId for
1997 the following requests.
1999 Implemented extended service handling for server. See ztest.c
2000 for an example as well as backend.h. New handlers are registerd
2001 in the Init handler.
2003 * Changed interface for sort in server.
2005 Added new members to statserv_options_block. It allows a server
2006 to read options from another source than just the command line. Thanks
2007 to Charles Woodfield.
2009 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2010 renamed to zboolean. Some C++ compilers complained about the name.
2012 Minor changes to gils.abs. Added index 's' (sort) on title
2013 and date/time-last-modified.
2015 --- 1.4pl2 1998/1/30
2017 Fixed bug in server library regarding inetd mode (-i). This bug
2018 was introduced by release 1.4.
2020 --- 1.4pl1 1998/1/29
2022 Added sort facility in client and backend server interface.
2024 Fixed problem with dependencies in Makefile(s).
2026 Fixed bugs for encoders/decoders of extended services and
2029 Implemented sub-tree feature for schemas. Sub-trees are
2030 referenced in *.abs-files. See explain.abs for an example
2031 of the use of this feature.
2033 Modified bib1.att; local attributes for ANY didn't include
2034 ANY itself (only affects use of the retrieval module).
2036 Fixed bug in plain SGML reader in function data1_read_node:
2037 tags with prefix "var" was incorrectly interpreted as variants.
2039 Added feature "sub-schemas" to enable references to - and definitions
2040 of - group of elements.
2042 * Removed member parent from type data1_element (in data1.h).
2044 Implemented function odr_nullval() that returns the value of
2047 * Removed member num_children from data1_node (in data1.h).
2049 Made NT service interface part of the server library. The
2050 function statserv_main uses the NT service when required and
2051 calls the statserv_start / statserv_close routines.
2053 Routine zget_SearchRequest and zget_PresentRequest fills
2054 resultSetName/Id member with "default" instead of "Default".
2056 Fixed memory leak in server. Request queue member wasn't freed.
2058 Fixed nmem_exit so that memory is freed.
2062 Revised the CCL parser utility to be thread safe.
2064 Added function, oid_ent_to_oid, to replace the function
2065 oid_getoidbyent, which is not thread safe.
2067 * Added nmem_init and nmem_exit to initialize and release
2068 NMEM resources. Function nmem_init should be called once in the
2069 initial thread before NMEM/ODR is used. statserv.c and client.c
2070 have been changed accordingly. The change was necessary to make
2071 NMEM thread safe. The NMEM memory pool is shared amongst threads
2072 in a process. Unix-based applications will still work fine without
2075 Added NT Services interface for the the Z39.50 (statserv) Server.
2076 Refer to the ztest.c source on the usage.
2078 Windows 95/NT port using MSVC5.0. Project files are included in the
2081 * Defined new 'global' handle for the retrieval (data1) system. The
2082 new handled, data1_handle, describes the state of the data1 system.
2083 This handle is passed as first argument to virtually all
2084 data1 related routines. The functions data1_create and data1_destroy
2085 creates and destroys a data1 handle respectively.
2087 Added ODR encode stream member to all backend request structures
2088 init, search, scan etc. This stream should be used to allocate all
2089 memory used for the response when thread safe operation is needed.
2091 Changed the comstack utility, cs_addstr, to be thread safe. The
2092 returned hostname string returned by the function is now part the
2095 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2096 function. The cs_straddr takes a COMSTACK handle as argument, so this
2097 function must be used after cs_create and before bind/connect.
2098 This function is thread safe.
2100 Moved test server to 'ztest' directory - generic server code still
2101 in 'server' directory.
2103 Made prefix query (pquery.c) utility thread safe.
2105 Added new function modifier YAZ_EXPORT to 'export' public DLL
2106 functions when using windows (see include/yconfig.h).
2108 Added definitions to the OID database (util/oid.c) (RVDM).
2110 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2112 Added call to ccl_rpn_delete in client program.
2114 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2115 release of RPN structure.
2117 Added support for C++, headers uses extern "C" for public definitions.
2118 With input from RVDM.
2120 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2121 Thanks to Ronald van der Meer (RVDM).
2123 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2125 Added support for private extensions to the OID database
2126 (oid_setprivateoids()). Thanks to RVDM.
2128 Added optional, physical ANY (key replication)
2130 Fixed null-reference problem in GRS-1 output filter.
2132 Proximity operator added to Prefix Query Format (PQF).
2134 In test client command "base" accepts multiple databases.
2136 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2140 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2142 Smallish bug-fixes in the new encoders/decoders (explain).
2144 Bug fixed in DeleteRequest.
2146 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2148 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2150 Added SOIF syntax (using private OID for now) to retrieval module and client.
2152 Added Update extended service.
2154 Added SearchResult-1 additional info structure.
2156 Added optional CCL (ISO8777) interpreter as separate module. Available
2159 --- 1.2 1996/6/10 (1st anniversary release)
2161 Added Summary record syntax. Lightly tested.
2163 Added OPAC record syntax. Untested.
2165 Added ResourceReport service encoders/decoders. Untested.
2167 Fixed bug in z_Unit - wrong tagging on unitSystem.
2169 Fixed bug in the DiagRecs decoder.
2171 Added options for max PDU size and session timeout to frontend-server.
2173 Added documentation of query-language parsers and other supporting utilities.
2175 [frontend-server] Added Attribute set to the bend_scanrequest API.
2177 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2178 surrogate diagnostics were generated.
2180 [retrieval] Allow multiple local values for attribute.
2182 [retrieval] Allow multiple attributes per element in .abs files. index type.
2184 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2186 --- 1.1pl2 1996/4/10
2188 Minor changes, mostly specific to Zebra's requirements (retrieval)
2192 Repaired bug in frontend server when running multiple listening
2193 endpoints in dynamic mode.
2195 z_External() now won't break if a known, ASN.1 value comes encapsulated
2196 in an octet-string. The value will pass through unmodified in an Odr_oct.
2198 Added a bit of code to the demo client to decode & display
2199 ASN.1-structured records represented in the octet-aligned branch of
2200 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2202 Added z_ext_getentbyref() to the ASN module. Doc updated.
2204 * Completed the SCAN definition in the ASN module. This may break SCAN
2205 code based on older YAZ-versions at compile-time. The fix is easy -
2208 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2209 under the SCAN definition. Remember to initialize this, server-people.
2211 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2212 that this does not extend to ODR and ASN.
2214 Comstack allows insertion of established socket (primarily for
2215 inetd-operation of servers). Doc updated.
2217 Front-end server can now start from the inetd in TCP mode. Doc
2220 --- 1.0pl4 1996/1/24
2224 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2225 the rank and record number.
2227 Adjustments to the frontend server.
2229 Fixed diagnostic BER dumper. It ignored the file argument.
2233 Various changes to retrieval module.
2235 Changed the union discriminators of the protocol files from enums to
2236 ints paired with #defines.
2238 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2241 *Changed operator in the RPN structure to 'roperator', again to avoid a
2244 Fixed problems in Explain decoders/encoders.
2246 --- 1.0pl2 1995/12/6
2248 Memory bug in log module fixed.
2250 --- 1.0pl1 1995/12/5
2252 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2254 Bug in Explain DatabaseInfo module fixed.
2256 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2260 The shift to v1.0 signals that we now consider the *core* functionality
2261 of YAZ reasonably stable (the core being more or less equivalent to
2262 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2263 tested (Explain not at all - though that will happen soonish).
2265 Minor changes to code to support Windows port.
2267 Various minor changes after we're getting to use GRS-1 & co. more.
2269 Added Espec-1 format.
2271 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2272 of the protocol and it cannot be selected when encoding (maps into 'string'
2273 when decoding). Needed to talk to some servers.
2275 Demo client can request simple element set names.
2277 Added Diagnostic Format encoders/decoders.
2279 Added simple Close handling to frontend server (no hooks for resource
2280 reporting yet), and demonstration client.
2282 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2284 --- 1.0b3 1995/08/24
2286 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2287 handled incorrectly when records were requested in the searchResponse. This
2288 will only affect you if you use the frontend-server.
2290 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2291 Test-client will ask for and print GRS1. Ztest will return dummy records
2294 Added Explain encoders/decoders to the service-level API. Untested.
2296 Added Extended Services: Item Order encoders and decoders to the Service-
2297 level API. Untested. We could use a recent copy of the pertinent bits
2298 of the ILL protocol to add those bits.
2300 Added diagnostic format 1 encoders/decoders to the service-level API.
2303 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2304 odr_cons.c, which causes a more correct output.
2306 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2307 was always set to 0 when no records were requested in the searchRequest.
2309 * Added better external-handling. This shouldn't harm old code that
2310 *encodes* externals. It can break code that looks for a
2311 'single-ASN1-type' representation, since those types that are known
2312 are now decoded immediately. Look at the SUTRS sample code in
2313 seshigh.c and client.c. Documentation updated.
2315 Handling of structured records in bend_fetchresponse. Length -1 marks
2316 structured record, type is deduced from format field.
2318 --- 1.0b2 1995/06/27
2319 Fairly quick maintenance release to add SUTRS support.
2321 Fixed handling of SUTRS records in the demonstration client.
2323 * Added format field to the bend_fetchrequest and bend_fetchresponce
2324 structures of the backend API (frontend server). When the record is
2325 returned, the value of the format field is mapped to an OID. The
2326 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2327 of the record. The special value VAL_NONE in the bend_request means
2328 that no specific format was requested by the client. Documentation
2329 updated accordingly. Test server (ztest) will return a fixed dummy
2330 SUTRS record if your client requests SUTRS.
2332 Documentation updated accordingly.
2334 You can now set external libraries and RANLIB support in the top-level
2338 First public release.
