3 yaz-client's itemorder command may now send a file.
5 Fixed yaz-marcdump to allow the use of NS prefix for record element.
7 Added new function yaz_log_xml_errors.
9 Allow (but warn) unknown XML attributes in MARCXML parsing.
11 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
13 The UTF-8 to MARC-8 conversion now uses a different set of characters
14 for Greek symbols. Bug #2120.
18 Added yaz_daemon (daemon.h).
20 Fixed bug #2068: pkg-config trouble
22 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
26 Document --with-xml2 option.
28 Added OPAC XML XSD (etc/opacxml.xsd).
30 Allow glob mask for name attribute in retrieval element for the
31 generic frontend server's retrieval facility.
33 Changed yaz_poll_poll to return yaz_poll_except for all returned events
34 except POLLIN/POLLOUT.
36 Fixed error handling in cs_listen. Bug #2037.
40 Fixed version in yaz/yaz-version.h.
42 Fixed bug #2027: Crash when closing connection.
44 Changed configure so that ICU support is only enabled if only ICU
45 and Libxml2 is available (because the ICU chain is XML based).
49 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
50 is built. Only this DLL depends on the ICU runtime.
52 yaz-ziffy is no longer part of YAZ. It is distributed separately by
53 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
55 Changed license of CCL module to 'Revised BSD'. After consultation with
56 remaining members of the original EUROPAGATE consortium, we are re-issuing
57 the CCL module without a separate license. The software was developed by
58 Index Data as part of a research project. The special license was included
59 to help feed usage information back to the project consortium to support
60 project evaluation. At this time, the project consortium has long-since
61 disbanded, and the majority of the original principals have retired. At the
62 same time, we have significantly modified the software during the following
63 years, to the point where very practically no original code remains. To
64 simplify re-use of the software, we have contacted those members of the
65 consortium who could be reached, and agreed to re-issue the module as a
66 proper part of the YAZ package.
68 Tcl scripts uses /usr/bin/tclsh as preferred shell.
70 CQL closer to being version 1.2 compliant. CQL also allows free-form
71 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
74 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
75 bug could make Extended services handling crash in the ZOOM layer. This
76 bug was only present in YAZ 3.0.18.
80 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
83 yaz-marcdump reads and writes collection wrapped records.
85 Handle OPAC for record conversion module.
87 Fixes for ICU wrapper.
89 Allow ICU libs to be controlled with --with-icu .
93 Added yaz_poll which is a wrapper for select/poll. When poll is available
94 and non-buggy, it is used, by yaz_poll . This allows more than 1024
97 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
98 functionality through an XML based configuration (ICU chain). This system
99 is useful for search facilities such as Pazpar2 and Zebra that needs to
100 perform tokenization of indexed material. The ICU code in a separate
101 library libyaz3_icu.a.
103 Added HTTP tunnel facility for COMSTACK, bug #1752.
104 This is a facility that allows a Web proxy, such as squid, to tunnel
105 Z39.50 traffic. This facility is "transparent" to must applications
106 using YAZ. It's enabled by using pseudo transport connect: followed by
107 the proxy address, followed by command, then follwed by he regular
108 "virtual" addresss. For example,
109 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
111 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
113 --- 3.0.14 2007/09/21
115 Fixed bad memory reference in ZOOM_record - cuased by member not being
116 initialized. This was a problem only in YAZ 3.0.12.
118 Fixed bug in conversion from MARC to XML: Non-XML characters in control
119 fields were not removed.
121 Changed the way C code is generated from codetables.xml. Made a MARC-8
122 conversion trie for each characterSet section rather than codeTable.
123 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
124 of codetables.xml from Larry Dixson, LOC. Bug #1464.
126 --- 3.0.12 2007/09/12
128 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
129 from ZOOM_record_error).
131 ZOOM C function ZOOM_record_get returns record schema for type="schema".
133 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
135 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
137 Better SRW-to-Bib-1 diagnostic mapping.
139 ZOOM C and yaz-client announces SRU version 1.2 by default.
141 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
144 Fixed in yaz_sru_decode to allow other version than 1.1.
146 --- 3.0.10 2007/08/22
148 Added support for SRU scan for ZOOM.
150 Added support for the use of the older versions or Extended Service
151 Update in ZOOM. To faciliate this, an option "updateVersion" may be
152 set to the version , 1=first, 2=second, 3=third. The third version is
153 what ZOOM C has used so far. And that, obviously, is the default.
155 Added support for CCL queries in Z39.50 queries sent to the GFS (and
156 therefore in Zebra and in SimpleServer-based applications). The new
157 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
158 qualifier file used to transform incoming CCL queries into Type-1 RPN,
159 which is passed into the back-end search callback function.
161 Added support for HTTP Basic authentication in clients: the SRU/W
162 codec encodes the username/password elements of the PDU structure
163 appropriately, and these may be set using the "user" and "password"
164 options in ZOOM-C applications (the same options that are used for
165 Z39.50 authentication).
169 Fixed bug #1208: SSL appears to be broken in ZOOM.
171 Fixed bug #1206: Libxml2 include path weirdness.
173 Added oid_name_to_dotstring.
175 Allow elementSetName to be specified for ZOOM C record update.
177 Allow waitAction to be specified for ZOOM C based for Extended Services.
179 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
180 syntax OID. Bug introduced in YAZ 3 series.
182 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
186 Fixed bug #1157: yaz-client does not read .yazclientrc from current
187 directory. yaz-client now reads commands from file given by option -f
188 if specified; then tries to read .yazclientrc in current directory.
189 Failing that, it reads .yazclientrc from user's home directory.
191 Added support for correlationInfo Note and ID for Record Update via
194 Added yaz-client command querycharset which specifies character set for
195 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
196 (termListAndStartPoint).
198 Charset ISO5428:1984 is an alias for ISO5428-1984.
200 Implemented a way to perform scan in a result set using Z39.50. This
201 is achieved by attaching the result set name in the characterInfo
202 (type InternationalString) of OtherInformation in the Scan Request PDU.
203 The result set is identified in the otherinformation by the new OID:
204 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
205 This allows for scan in result set and faceted search . Zebra did some
206 of this in the APT term using attribute type 8 and value being result
207 set. Using the OtherInformation approach for this is cleaner and easier
208 to work with in proxies and the like. This facility can be used in
209 yaz-client using new command setscan which takes a result set as first
210 argument, start position (APT) as second.
212 Changed decoding of SRU XML packed records to deal with servers that
213 have recordData with XML data with multiple root nodes. Also make
214 comparison for recordPacking case insensitive. Again, one server
215 returns "XML" where others return "xml".
217 For SRU responses allow Content-Type application/xml as well as text/xml.
221 Fixed bug in character set conversion of BER strings. Bug introduced
226 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
228 For OID class, use oid_class consistently.
230 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
233 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
234 character set for bibliographic information interchange". By Giannis Kosmas.
236 Added documentation on new OID API.
240 Changes to generic frontend server interface: added new member
241 'query_charset' for bend_initrequest structure. A backend init handler
242 should set this member to its native character set for query terms.
243 When defined, the frontend server logic will announce this character set
244 to a client if the negotiationModel bit is set by the client. All server
245 implementors are encouraged to specify this. If a backend server does not
246 specify this a warning is issued using yaz_log(YLOG_WARN,..).
248 Added CCL utility to remove terms (stop words) from resulting RPN
249 tree. This is handled by functions with prefix ccl_stop_words_ .
251 New ZOOM C option, "rpnCharset", which allows client-side conversion of
252 terms in RPN queries.
254 Clean-up the CCL API. Moved some internal structures from ccl.h to
255 private header cclp.h. Changed ccl_parser_create so that a Bibset must
256 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
257 This is replaced by ccl_parser_find_str which takes a string instead.
259 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
260 libyaz.la is the core of YAZ except the generic frontend server and
261 does not depend on POSIX threads anymore. libyaz_server.la is the
262 generic frontend server facilities and uses POSIX thread functionality
263 if available. The libyaz.la no longer depends on POSIX threads because
264 the number of global structures is limited. NMEM no longer re-uses blocks
265 between threads ; it simply free's memory immediately but allocates in
266 "large" chunks as usual. We don't expect any performance penalties
267 because of this. The yaz_log system is still using a global log_level so
268 caution must be taken when modifying it with yaz_log_init_.. +
269 yaz_log_mask_str. This, however, should not cause any trouble because
270 these functions are called during initialization of application code
271 anyway. `yaz-config --libs server` returns libs for server applications;
272 `yaz-config --libs` returns libs for non-server applications.
274 New OID database - with public definitions in oid_db.h. Removed old OID
275 database including the head oid.h and definitions such as enum oid_value
276 and struct oident. The new OID database uses the same string names as
277 before but the 'protocol' is gone. There are now only two representations
278 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
279 converts from string to OID; functions with prefix yaz_oid_to_string
280 converts the other way.
282 Change to emit_term() in CQL-to-PQF query translation: when a term has
283 the /regexp relation modifier, do not process it for leading and
284 trailing "^" and "*", which have quite different meanings in regular
287 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
288 write handlers no longer carries a 'last' parameter. This will make
289 yaz_iconv flush "less" characters. A flush is performed by call to
290 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
292 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
293 removed, because function yaz_query_to_wrbuf does the same.
295 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
296 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
298 Deprecated MARC utility functions removed.
300 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
303 Branch split: YAZ_2_1_55_branch
305 --- 2.1.54 2007/03/16
307 Fix to ZOOM-C so that transparent reconnection is properly handled on
308 connections that are in asynchronous mode.
310 Fixed compilation on OpenBSD 4.0.
312 Large strings in GRS-1 records are now properly displayed in yaz-client.
314 Added character conversion support for "advancegreek"; based on patch from
317 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
318 sequence is met. Before the error was not set so it would be unknown.
320 Adjust yaz-marcdump MARC reader so that it skips until record separator
323 --- 2.1.52 2007/03/07
325 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
326 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
327 fd_set structure used as a bitmask for the FDs to be selected on.
329 Using ACX_PTHREAD macro to check for POSIX threads.
331 Fixed have-vsnprintf check.
333 --- 2.1.50 2007/02/23
335 Fixes for configure on BSD. Bug #900.
337 Added snprintf/vsnprintf wrappers for systems that don't have
338 limits (heavens forbid).
340 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
341 created before all previous tasks were completed and removed from the
342 task queue, the new task could be removed by a mistake.
344 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
346 Implemented pass-through CQL-to-PQF conversions. Bug #861.
348 Fixed bug #832: Problem with MARC/charset in yaz-client.
350 Fixed bug #668: save command line history for yaz-client.
352 Fixed bug #830: pkg-config support.
354 --- 2.1.48 2007/01/23
356 Extended ZOOM result set options with two options that may be read by
357 a client: resultSetStatus and presentStatus with values as specified for
359 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
361 Fixed bug #827: Using SSL fails on Debian etch.
363 Fixed bug #826: Weird looking chars for set of MARC records.
365 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
366 that is treated as an ItemOrder with itemRequest being an XML document
367 external. The value of "doc" is the content.
369 Extended the GFS search facility. New member of bend_search_rr
370 'estimated_hit_count' signals that hits is known to be an estmate
371 (higher or lower than real hit count). New member 'partial_resultset'
372 signals that the search was partial (hit count is lower or equal than
373 real hit count). For Z39.50, the information is stored in resultSetStatus
374 member of SearchResponse APDU. For SRU, the information is signalled
375 via SRU diagnostic 59: "Result set created with valid partial results
378 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
380 --- 2.1.46 2007/01/13
382 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
384 Added ZOOM_connection_peek_event.
386 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
387 the following new functions:
388 ZOOM_event_nonblock, ZOOM_connection_process,
389 ZOOM_connection_get_{socket,mask,timeout},
390 ZOOM_connection_fire_event_{timeout,socket}.
391 The existing blocking event handler, ZOOM_event, is a wrapper for the
392 + blocking ZOOM_event_sys_{poll,select}.
394 Implemented function ccl_xml_config which parses XML version of CCL
395 configuration (bug #798).
397 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
399 Added timings utility (yaz/timing.h)
401 --- 2.1.44 2007/01/03
403 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
406 Fixed bug #779: Rotation of apdu.log fails.
408 Fixed for character set conversions:
409 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
410 Honor G1 set in MARC-8 decoding.
412 --- 2.1.42 2006/12/17
414 Fixed bug #775: char conversion does not handle Alternative UTF-8
417 Implemented function yaz_marc_read_line which parses MARC line format
418 records. There is a wealth of formats out there. So far, this function
419 reads line records produced by yaz_marc_write_line.
421 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
422 more generic and easier to remember(!) options: -i format and -o format
423 which specifies input format and output format respectively - where
424 format is one of "marc", "marcxml", "line", "marcxchange".
426 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
427 does not print anything except warnings for records.
429 For yaz-marcdump, added support for MARC split into files (-s) with a given
432 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
433 spec, at http://www.loc.gov/standards/sru/record-update/
434 This has changed the binary layout of the following structs:
435 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
436 bend_update_rr . Patch by Ko van der Sloot.
438 Added GFS utility function bend_assoc_is_alive which returns 1 if
439 association is still alive (client is connected); 0 otherwise (client
440 closed connection). This allows busy servers to stop working for
443 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
444 been a separate piece of software. This version of ziffy has been modified
445 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
447 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
449 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
450 Client code may now interrogate options such as "init_opt_sort" to
451 find out whether the server claims to support various options.
453 --- 2.1.40 2006/11/27
455 Added utilities yaz_{set,get}_esn to set/get element set name from
458 Removed the build of libyazthread.la. The libyaz.so is the threaded version
459 of YAZ and has been so since YAZ 2.1.10.
461 Implemented ZOOM_record_error which returns error information for
462 record (surrogate diagnostic).
464 --- 2.1.38 2006/10/31
466 Updates for SRU Update by Ko van der Sloot:
467 1. Changed name from "operation" to "action"
468 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
469 versions in the code, marked as 'backward compatible'.
470 3. Added diagnostics for SRU Update.
472 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
474 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
476 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
478 For GFS, fixed problem with SRU diagnostic 'First record position out of
479 range' being issued for 0 hits.
481 zoomtst10 part of Windows Build.
483 --- 2.1.36 2006/10/13
485 Implemented yaz_filepath_comp which splits a path into file path
486 components (required by Zebra 2.0.3+).
488 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
489 BSD inspired license until now so this should not have any real impact on
490 anybody. See http://www.opensource.org/licenses/bsd-license.php
492 Fixed bug #687: Missing log lines.
494 Fixed bug #678: CQL to PQF translation does not preserve double-quote
497 Fixed bug #689: SRU diagnostics to be added.
499 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
500 whether a connection is idle (no more work do do).
502 --- 2.1.34 2006/10/04
504 Change type of optval from long to int for invocation of setsockopt with
505 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
507 Added support for specifying the max log file size for the Generic
508 Frontend Server. The size is given with option -r.
510 --- 2.1.32 2006/09/21
512 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
514 --- 2.1.30 2006/09/17
516 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
519 Fixed bug in Generic Frontend Server that could cause a server to stop
520 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
522 For the generic frontend server, the maximum record size is used as maximum
523 size of incoming packages (SRU + Z39.50). The value until was previously
524 only used in Z39.50 Init negotiation and, later, in a session controlled
525 sizes of records returned. This is controlled using -k option. It can be
526 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
528 --- 2.1.28 2006/09/04
530 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
533 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
535 New option for yaz-marcdump -lpos=value which allows setting a portion
536 of MARC header to a certain value.
538 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
540 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
541 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
543 --- 2.1.26 2006/08/15
545 Fixed problem with SRU mode type (soap, get, post) for yaz-client
548 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
550 --- 2.1.24 2006/08/08
552 Fixed MARC ISO2709 encoding routines to deal with character set
555 Minor changes to GFS logging. Database included in search request log
558 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
559 cached/multiple records.
561 Shared libraries are built by default on Unix+configure.
563 Changed cql2pqf transformation to use a different evaluation order. The
564 new order is: always, relation, structure, position, truncation, index
565 and relationModifier. Old order was: always, relation, relationModifier,
566 structure, index, position, truncation. Note that the the latter ones
567 override former ones for identical attributes.. The new scheme means that
568 it is possible to override any existing attribute with a relationModifier.
569 And also that it is possible to override everything for the index rule
570 (except the ones listed in relationModifier). No order is perfect but this
571 one, we believe, covers more real cases.. The "always" should have been
572 called "default", since the attributes there can be overridden with all
575 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
576 compilation phase, but also for yaz-config --cflags output. This allows
577 us to have public headers with Libxml2 stuff in them . It should also,
578 eventually, make Libxml2 checks redundant in packages using YAZ, such
581 --- 2.1.22 2006/06/15
583 Changed SRU update structure bend_update_rr so that SRU diagnostics are
584 stored in uri, message and details.. Previously diagnostics were stored
585 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
586 compatibility.. but he's probably the only one affected, so.
588 Added support for CCL, compiled on the client side, in ZOOM-C. This
589 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
590 input; the resulting query objects can be used for for searching with
591 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
593 YAZ' configure searches for OpenSSL by default.
595 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
596 SL_CTX_use_certificate_file. See
597 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
598 for more info. Thanks to Ko van der Sloot.
600 --- 2.1.20 2006/06/02
602 Bug #600: SRU GET, POST support for yaz-client. Introduced
603 command 'sru' which selects method SOAP/GET/POST.
605 Allow missingValueAction to be specified for the sortspec string -
606 function yaz_sort_spec. By default, the missing value action is null.
607 Use ! to specify "abort". Use = followed by stringvalue to specify default
610 Ensured that Present-handler (if defined) is called in GFS before any call to
611 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
612 searchRetrieve requests.
614 Documentation for YAZ is now based on the Docbook XML/XSLT using
615 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
616 is no longer depending on jade/openjade or docbook-to-man scripts.
617 PDF is no longer part of the distribution - but can optionally be
618 made using DSSSL/jadetex or FOP.
620 Added retrieval handling support in Generic Frontend Server to support
621 conversion between MARC/XML as well as XSLTtransforms. See
622 etc/yazgfs.xml for an example.
624 Added Authentication support to Generic Frontend Server in SRU
625 mode. Authentication using HTTP Basic is supported, as is the use
626 of 'x-username' and 'x-password' parameters in the request itself.
628 Added support for a new character set MARC8s identical to MARC8 except
629 that it converts combined characters to single Unicode characters in the
630 Latin-1 range (when possible).
632 --- 2.1.18 2006/04/24
634 ASN.1 compiler 0.4: generates brief Doxygen file header for
635 generated .h/.c files.
637 Utility yaz_iconv now supports conversion to MARC-8.
639 New facilities for the MARC module. The reading - and writing of
640 content are separate methods for the yaz_marc_t handle. The following
641 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
642 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
643 format). Write functions have prefix yaz_marc_write_.. The existing
644 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
645 available. Removed support for OAI-MARC and simplexml (not the
646 simplexml from PHP5).
648 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
649 to be returned for this connection.
651 --- 2.1.16 2006/03/31
653 Allow multiple languages and charsets to be specified with
654 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
655 negcharset iso-8859-1,utf-8
657 Translation of proximity nodes from CQL into PQF now works.
659 Moved to automake 1.8, 1.9.
661 Added function yaz_log_set_handler which allows a log handler to be
662 installed. This handler will be called for all log messages. Output
663 to file is also produced; but that can be disabled by passing NULL
664 fname to yaz_log_init_file.
666 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
668 For SRW (including GFS), accept application/soap+xml as content-type
671 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
672 produces NO stylesheet reference even if a default stylesheet is specified
675 --- 2.1.14 2006/03/14
677 Updated Windows package to include yazd.dll + yazd.lib for the
678 Development component.
680 If the environment variable YAZ_LOG is set, then it is used as a
681 string indicating the default level of logging to use if not
682 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
683 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
684 used as before. So, for example, to omit warnings from YAZ logging,
687 cql_transform() now map structure and other attributes before indexes,
688 so that index-specific structures and other attributes can override
689 defaults. So now a combination of mapping specifications such as:
691 index.dc.date = 1=date-modified 4=5
692 does the right thing.
694 cql_transform() now also respects the "always" mapping specification,
695 which establishes an initial set of attributes to be used for all
696 terms except where overridden by more specific attributes associated
697 with the index, relation or modifier.
699 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
700 which mode to use; one of "post", "get" or "soap" (SRW, default).
702 Fixes for yaz_iconv routines: changed trie-based character set conversions
703 to use only non-negative values for bit fields due to Sun's C compiler not
704 supporting negative values.
706 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
707 sequences where not read correctly. Fix by Rustam Usmanov.
709 Updated win/makefile to use options, settings which makes things
710 compile with VS C 2005.
712 --- 2.1.12 2006/02/01
714 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
716 In ZOOM socket code, use select instead of poll on MacOSX.
718 ZOOM-C now support client-side compilation of CQL into RPN that is
719 sent to the server, enabling CQL to be used against all Z39.50
720 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
721 ZOOM_query object, and submit it using ZOOM_connection_search().
722 The CQL-to-RPN translation uses a configuration file, the name of
723 which must be specified in the Connection's "cqlfile" option.
725 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
726 function, which takes as its start-term parameter a ZOOM_query object
727 (which may have had either CQL or RPN set into it).
730 --- 2.1.10 2005/11/29
732 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
733 GFS to support this as well. Backend handler, bend_srw_update, does the
734 update work. Code contributed by Ko van der Sloot.
736 Allow retrieval of Search Result-1 information in ZOOM by the use of
737 options that are attached to a result set. ZOOM documentation updated
740 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
741 UTF-8 conversion. Patch by Raj Patel.
743 Added option -m to GFS to control formatting of timestamps in log file.
745 Added 'exit' as synonym for 'quit' in yaz-client
747 Added support for specifying SRW resultSetId + resultSetIdleTime in a
748 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
749 for the new members. Patch by Ko van der Sloot.
751 Added support for SRU POST. It is supported for content-type
752 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
754 Do not build the separate Multi-threaded (MT) library libyazthread.la.
755 Instead make the library libyaz.la multi-threaded. Threading as a whole
756 can still be disabled by configure option --disable-threads. Previosly,
757 with older GLIBCs there were problems with MT libs under Apache. This
758 has now been fixed a long time ago.
760 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
763 CQL module modified to be case insensitive for relations/indexes/operations.
765 Fixed bug in CQL transform code: incorrect value relationModifieder
768 Added 'show all' command for yaz-client which retrieves all results
771 Added new yaz-client, xmles, which takes a (private) OID and
772 a document to be sent as an extended service request.
774 Describe new yaz-client commands wait_response and set_auto_wait.
776 Increase TCP/IP listener backlog from 3 (which I am guessing was
777 copied from the SunOS manual entry way back when) so SOMAXCONN, so
778 that the socket will queue as many incoming connections as it's able
779 to handle ongoing connections. In other words, it will never now
780 refuse a connection that it would be able to handle merely because
781 it's not got around to accepting() enough of the pending connections
782 yet. This is the behaviour anyway under Linux, where the listen()
783 argument is ignored; but not under BSD and on systems such as
784 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
785 YAZ-based servers should now be uniform across operating systems in
788 yaz-marcdump uses 64-bit file access on some systems. This is enabled
789 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
790 This allows yaz-marcdump to read large MARC batches (>2 GB).
792 Modified all YAZ source files - except the source which is auto-generated
793 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
796 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
797 corresponding to the existing *_setl() function. These allow option
798 values containing arbitrary valuues.
800 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
801 ZOOM_resultset_sort() in new applications. Its behaviour is identical
802 except that it returns an indicator of whether or not the sort
803 criterion was accepted (0 for OK, -1 for invalid).
807 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
808 MARC output rather than returning "new" buffer.
810 yaz-client warns about unknown init options.
812 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
816 Added support for SRW sort in Generic Frontend Server. Patch
817 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
818 sortKeys - or NULL if none is provided.
820 Fixed bug #307: It was impossible to specify indefinite/no timeout
821 for ZOOM_event. Special timeout value -1 now means indefinite timeout
824 Added support for multiple languages and charsets to be specified in
825 ZOOM. Each charset/language is separated by a blank. If negotiation is
826 in effect in init-response, Option
827 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
828 Code based on patch by Vasiliy Osadchuk.
830 Fixed bug #306: infinite recursion that occurred when calling
831 yaz_log_level_init as the first call (before other log level or
834 Fixed bug in scan handling in front end server: if preferred-Position-In-
835 Response was non-present, a NULL pointer referece was performed.
839 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
840 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
841 now defined for all those error codes. So instead of putting 109 in
842 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
843 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
845 Modified the yaz-marcdump utility to skip garbage bytes between MARC
848 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
850 Program yaz-client now exits and produces an error message if multiple
851 Z39.50 servers are specified on the command line (none or one allowed
854 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
859 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
861 Fixed bug #272: Preserve spacing for CCL terms.
865 Added support for virtual hosts and multiple backend servers for
866 the YAZ frontend server. The configution is XML based and
867 support specificition of CQL to RPN mappings and explain information.
868 See section "Virtual Hosts" in the YAZ manual.
870 Extended OPAC display utility. OPAC display utility renders
871 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
872 to supplement yaz_marc_decode_wrbuf.
874 Fixed a bug in MARC decoder that could caused it to crash for some
875 invalid MARC records. More diagnostics and warnings where added in
876 XML output (warnings, etc are stored in comments).
878 --- 2.0.34 2005/02/08
880 Fixes for UNIX domain sockets. Bug #261.
882 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
884 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
885 Added yaz_marc_subfield_str which defines subfield lead string which is
886 used in YAZ_MARC_LINE format. Default string is blank+$. Added
887 yaz_marc_endline_str which defines end of fields string used in
888 YAZ_MARC_LINE format. Default string is newline.
890 Experimental support for MarcXChange. This format can be produced
891 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
892 http://www.bs.dk/standards/MarcXchange.xsd
894 Added yaz-client commands scansize that sets maximum number of
895 entries to be returned by scan.
897 --- 2.0.32 2005/01/11
899 Added support for SRW scan in yaz-client and Generic Frontend Server.
901 * Added whereInList member to SRW Scan Term.
903 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
905 Fixed NMEM system to return aligned blocks on the smallest boundaries
906 that are suitably aligned for all possible types on the particular
907 architecture YAZ is being built for.
909 --- 2.0.30 2005/01/04
911 Fixed numerious warnings that was issued with newer versions of GCC.
913 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
914 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
917 Make YAZ Generic Frontend Server slightly faster.
919 Enhance (and reduce) logging for Generic Frontend Server.
921 Revert YAZ log system so that it flushes every write operation
922 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
924 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
925 instead of LOG_, due to name clash with syslog(3). LOG_ are still
926 present. New applications should define YAZ_USE_NEW_LOG=1 - this
927 will effectively disable old definitions.
929 --- 2.0.28 2004/11/09
931 Added yaz_log_time_format which specifies log format using
934 Added yaz_log_module_level which returns mask for a module. Value
935 is non-zero mask a if module is enabled; zero if disabled.
937 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
938 in include/yaz/cql.h.
940 Fixed bug #176: Dont throw diagnostics on empty SRU args.
942 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
944 Fixed bug #172: RPM builds does not enable SSL.
946 Doxyfile.in part of dist. Doxyfile generated by configure.
948 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
949 are given and the corresponding component does not exist.
951 Extend CCL documentation in YAZ reference. Describe r=r.
953 --- 2.0.26 2004/10/01
955 Fixed MARC->MARCXML conversion to properly deal with
956 fields, subfields, indicators having non-ASCII characters.
958 Fixed MARC->MARCXML conversion so that ASCII control characters
959 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
962 Added YAZ GFS support for conversion from Z39.50 surrogate
963 diagnostics to SRW surrogate diagnostics.
965 Bug fix: YAZ GFS did not return schema in explainResponse.
967 --- 2.0.25 2004/09/30
969 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
970 now converts recordSchema to elementSetName as well as schema URI.
972 Fixed bug in COMSTACK that prevented HTTP request packages from being
975 --- 2.0.24 2004/09/29
977 Added CCL facility r=r "range" which is similar to r=o "ordered" but
978 does not require white-space before and after the dash in a range, e.g.
979 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
982 Fixed a few AC_TRY_LINK configure tests that did not operate properly
983 due to new GCC removing "redundant" code.
985 Added yaz-client commands scanpos and scanstep that sets preferred
986 position and step-size for scan.
988 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
990 Added CCL utility ccl_qual_buf which parses one or more CCL
991 spec lines in a buffer.
993 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
994 of name and value - ignoring empty lines and comments.
996 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
998 Added odr_get_element_path which returns current element path for an
999 ODR handle. This utility is useful in error handling or user-defined
1002 Added ODR_PRINT utility odr_set_stream which is is a more generic
1003 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1004 to a write function and pointer to close function. The close function - if
1005 non-NULL - will be called during odr_destroy.
1007 Fixed bug in CCL parser where truncation char was not removed from
1008 right side when truncation=both was in effect.
1010 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1013 --- 2.0.23 2004/08/11
1015 Fix buffer overrun in CQL parser when dealing with proximity (%).
1017 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1018 to UTF-8/UCS conversion is now only based on codetables.xml.
1020 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1022 --- 2.0.22 2004/08/06
1024 Add support for more "commit changes" in ZOOM (uses Extended Services).
1026 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1029 Yet another small fix for configure of SSL.
1031 --- 2.0.21 2004/05/14
1033 Fix SSL libs for configure when --with-openssl=DIR is given.
1035 --- 2.0.20 2004/05/10
1037 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1039 SSL comstack now uses yaz.pem certificate file on server side
1040 by default. Certificate filename can be configured by calling
1041 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1043 Fix bug regarding multiple calls to ZOOM_connection_connect.
1045 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1047 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1048 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1050 ZOOM now allows inspection of X509 peer certificate for verification.
1051 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1053 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1054 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1055 as "modular" but it simplifies things.
1057 Added cs_get_peer_certificate to that returns peer X509 PEM.
1059 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1060 NULL if SSL is unavailable.
1062 Documentation about MARC decoding tools.
1064 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1066 --- 2.0.19 2004/03/30
1068 Rename CHANGELOG to NEWS to follow GNU style packing.
1070 Fix bug with missing initialization of member in init_diagnostics.
1071 This bug affects threaded version of GFS server.
1073 --- 2.0.18 2004/03/20
1075 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1078 Ensure zlib.dll is packed with Windows install.
1080 --- 2.0.17 2004/03/17
1082 Fix encoding of xsd:string to use text instead of CDATA.
1084 Fix endless loop in CQL parser with unbalanced ".
1086 Use a more compact way to store MARC-8 conversion tables.
1088 --- 2.0.16 2004/03/16 Debian only
1090 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1093 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1098 --- 2.0.15 2004/03/01
1100 Another fix for decoding of XML packed records.
1102 --- 2.0.14 2004/02/25
1104 Fixes for Chunked encoding. White space not ignored after length spec.
1106 Update NS and use default NS for SRW diagnostic elements.
1108 --- 2.0.13 2004/02/23
1110 Implement ZOOM_resultset_cache_reset which resets record cache.
1112 Implement ZOOM_resultset_sort which sorts a result set.
1114 Implement chunked HTTP transfer.
1116 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1118 --- 2.0.12 2004/02/16
1120 Added member 'schema' to bend_explain_rr structure so that backend
1121 can specify explain record identifier. Defaults to Zeerex 2.0.
1123 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1125 --- 2.0.11 2004/02/16
1127 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1130 Added init command for yaz-client which sends "extra" init request.
1132 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1133 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1135 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1137 Make ZOOM error code for "invalid query".
1139 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1141 --- 2.0.10 2004/02/05
1143 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1146 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1148 Added option -p <file> to make Generic Frontend Server to write PID file.
1150 Added option -D to put Generic Frontend Server in background on its own.
1152 Make ZOOM C recognize option "password". If unset, "pass" is used
1153 (for backwards compatibility).
1155 Fixed a bug in Generic Frontend Server that could make it crash if a
1156 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1159 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1160 Must be issued before open, in order to be in effect.
1162 --- 2.0.9-6 2004/01/12 Debian/Windows
1164 Make the SRU server more picky WRT unknown params, etc.
1166 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1168 New YAZ client command, options, that sets Z39.50 options.
1170 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1171 options from a string of tokens (one token for each option bit).
1173 Update SRW diagnostic code messages.
1175 --- 2.0.9-5 2004/01/07 Debian/Windows
1177 Handle user defined stylesheet for SRW/SRU.
1179 --- 2.0.9-4 2004/01/06 Debian/Windows
1181 Fix bug in decoding of Content-Length.
1183 --- 2.0.9-3 2004/01/06 Debian/Windows
1185 Fix a bug with decoding of XML packed records.
1187 --- 2.0.9-2 2004/01/05 Debian only
1189 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1191 Fix bug in SRW/SRU diagnostics decoding.
1193 --- 2.0.9 2004/01/05
1195 Fixed bug in Generic Frontend Server which could drop records exceeding
1196 preferred message size. Reported and fixed by Irina Dijour.
1198 Fixed calculation of package size for structured records in Generic
1199 Frontend Server. Reported and fixed by Irina Dijour.
1201 Fixed namespace for SRW/SRU diagnostics.
1203 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1205 --- 2.0.8 2003/12/22
1207 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1208 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1211 CQL changes to reflect recent changes to the specification:
1212 * Documentation talks about context sets instead of index sets.
1213 * Documentation talks about indexes instead of qualifiers.
1214 * The CQL-to-PQF transformer's configuration file now uses
1215 "index.set.name = <attributes>" instead of the old form
1216 "qualifier.set.name = <attributes>". (Both forms are still
1217 understood but the latter is deprecated.)
1218 * CQL terms with no explicit index specified are now interpreted as
1219 cql.serverChoice instead of srw.serverChoice (which of course
1220 behaves exactly the same.)
1222 --- 2.0.7 2003/12/16
1224 MARC conversion can now generate ISO2709 output in another
1225 character set. yaz-marcdump uses this facility if you invoke it
1228 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1229 functions from there can be used from C++.
1231 --- 2.0.6 2003/12/04
1233 Frontend server now transfers memory from decoded packages to stream
1236 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1237 references to show up.
1239 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1240 the ZOOM Abstract API. The older names for the same options are still
1241 also supported for the benefit of old applications.
1243 ZOOM-C supports "implementationId" and "implementationVersion" options
1244 to go along with "implementationName". These allow the user code to
1245 specify identification strings to be sent to servers.
1246 Add OID for the new ExtLite attribute set.
1248 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1249 as requested/supplid by Ere Maijala <ere@atp.fi>
1251 For generic frontend server, reverse the order of
1252 "toolkit-supplied / application-supplied" strings sent as implementationId,
1253 Name and Version. Also, remove the spaces around the slash. This brings
1254 the GFS in line with the behaviour of ZOOM-C on the client side.
1256 Add function ZOOM_scanset_display_term.
1258 yaz-client shows scan displayTerm if present.
1260 Utility yaz-iconv is now installed by default along with the man page
1263 Extend configure check for OpenSSL to use pkg-config where available (such
1266 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1267 server to specify uid/gid/mask for socket using the format
1268 unix:[user=uid,][group=gid,][umask=mask,]file=path
1269 If file= is omitted the existing format is assumed, e.g.
1271 in which case the mask is 0666 (rw for everybody).
1273 Major restructure of YAZ source. All source in libyaz is in src directory.
1274 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1275 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1277 Added man page for utility yaz-marcdump (used to be called marcdump).
1278 yaz-marcdump is installed by 'make install'.
1280 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1281 of incoming package failed.
1283 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1285 Change prototype of odr_perror: add const to message string.
1287 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1289 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1290 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1291 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1292 DNS lookup. There should not be any compatibility problems with this
1293 assuming that blocking=1 or 0 is used.
1295 Fix bad reference in UNIX comstack in function cs_addrstr.
1297 Fix for compilation on AIX.
1299 The generic front-end server (server/seshigh.c) now supports returning
1300 Init diagnostics to the client in User-information-field, in
1301 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1304 --- 2.0.4 2003/09/04
1306 Allow any CQL relation (not just all,any,exact,scr).
1308 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1309 that features the same UI.
1311 Implemented command update0 in YAZ client which is equivalent to
1312 update but uses old of Ext Update ASN.1.
1314 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1315 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1316 Previously no OID was used for this info.
1318 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1319 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1320 returns 'malformed search term' otherwise.
1322 SortResponse member resultCount now set to NULL in sort handler of
1325 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1328 Add three new utility functions for translating OIDs between various
1329 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1330 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1331 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1332 char *oid_to_dotstring(const int *oid, char *oidbuf);
1333 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1335 Reverted modifications for ES Update definition for z_IU0Update
1336 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1337 is back to YAZ 2.0.2.
1339 String value attributes for CCL parser.
1341 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1342 which their FirstSearch server returns in Init responses, sometimes
1343 carrying useful diagnostic information when Init fails. This has the
1344 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1345 "z39.50/oclcui.asn", where its definition is somewhat different from
1346 what OCLC document on their web-site, as required to interoperate with
1349 Support for anonymous authentication in yaz-client. Use the command
1352 * Fix the OID of the Index Data-local "admin" Extended Service from
1353 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1354 the 1000, which indicates a locally-defined OID, was a mistake.
1356 --- 2.0.3 2003/06/20
1358 Fix CCL directive @case handling so that it affects string match for
1359 both CCL keywords and qualifiers.
1361 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1362 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1363 Decoder has been updated with ASN.1 changes as listed in
1364 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1365 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1366 z_IUUpdate, remains unchanged.
1368 ZOOM_record_get may now return a record in a specific character set.
1369 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1370 "from" is the character set of record as returned by target. "to" is
1371 the character set to be returned. If omitted, "to" is UTF-8.
1373 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1375 New ODR utility, odr_getelement, which returns name of element for
1376 which encoding/decoding failed.
1378 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1379 in cases where a required element was omitted.
1381 Bug fix: some MARC8 sequences were not converted.
1383 New ZOOM option "step" which specifies number of records to be
1384 retrieved in one chunk. Used in conjunction with "start" and "count".
1386 SRW support for yaz-client. Use scheme http: to use it, e.g.
1389 yaz-client no longer does (un)intelligent character set conversions
1390 by default. Can be enabled with charset and marc_charset commands.
1392 xmalloc trace fix for 64-bit systems such as DEC alpha.
1394 Solaris 2.6 compile fix.
1396 New function, cql_strerror() translates SRW error codes, as returned
1397 by cql_transform_error(), into human-readable English strings. Used
1398 in yaz-client diagnostics when appropriate.
1400 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1401 converts it into a type-1 query which is sent to the server. This
1402 makes CQL available for use with all Z-servers, as opposed to the tiny
1403 minority that can handle CQL queries themselves.
1405 --- 2.0.2 2003/04/28
1407 New Debian package layout similar to the Redhat Package layout.
1409 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1410 and search result respectively.
1412 --- 2.0.1 2003/04/25
1414 Redhat package is now several packages: libyaz (runtime libraries),
1415 libyaz-devel (development and documentation, and yaz (utility programs).
1416 Package spec file by Morten Bøgeskov.
1418 New member 'schema' in struct bend_fetch_rr which the name of requested
1419 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1420 handler MAY set this to reflect the schema of the returned record.
1422 New member 'display_term' in struct scan_entry. GFS now sets member entries
1423 and allocates scan entries to be filled by user scan handler. In previous
1424 version, entries member was allocated by the scan handler. That still works,
1425 but the GFS will ignore member display_term - assuming it was NOT set by
1426 the handler. The fact that the GFS now allocates the entries both allows
1427 for new members and makes a scan handler easier to write.
1429 Fix CQL lex buffer overflow.
1431 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1432 SRU default recordPacking is string.
1434 SRU protocol support for frontend server.
1436 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1438 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1440 Added scan for the ZOOM shell (zoomsh).
1444 * String Identifers for Schemas (Amendment 5).
1445 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1446 Old definition for schema
1447 Odr_oid *schema; /* OPT */
1452 Z_InternationalString *uri;
1453 #define Z_Schema_oid 1
1454 #define Z_Schema_uri 2
1457 * resultCount parameter to Sort Response (Amendment 1).
1458 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1460 Support for SRW 1.0 over HTTP. This is an optional feature and
1461 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1464 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1465 on the same port. SRW SearchRetrieveRequests are mapped
1466 to bend_init,bend_search,bend_fetch,bend_close.
1468 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1470 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1471 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1473 ZOOM connections are SRW based if schem http is used for hostname
1474 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1475 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1477 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1478 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1479 distance=n, order=true/false, relation=le, prox unit=word. If
1480 n is omitted, distance 1 is used.
1482 Fixed problem with C compiler include path in wrong order.
1484 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1485 on Solaris. Patch from Ko van der Sloot.
1487 New MARC decode API. All new functions operate on a yaz_marc_t
1488 handle. The most important new functions are: yaz_marc_create,
1489 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1490 decode and destroy respectively. Decoder can produce formats
1491 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1492 include/yaz/marcdisp.h.
1494 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1495 to UTF-8, UCS-32, wchar_t or Latin-1.
1497 * Prototypes for yaz_iconv_-functions moved to separate header
1498 include/yaz/yaz-iconv.h.
1500 Make a few private functions 'static' in unix.c. This prevents
1501 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1503 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1504 are set when Init Response is received.
1506 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1507 but returns diagnostic set as well.
1509 New function yaz_strerror which is a portable wrapper for
1510 strerror/strerror_r/GetLastMessage.
1512 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1513 is returned for MARC. If type is "oai", then OAI MARC is returned.
1515 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1518 --- 1.9.2 2002/11/26
1520 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1522 Fix bad race conditions on SIGTERM and terminate gracefully in
1525 Move retrieval (data1) module to Zebra since nobody seems to be
1528 Add GRS-1 render for ZOOM using same format as yaz-client.
1530 --- 1.9.1 2002/10/05
1532 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1534 Fix broken ESpec handling in data1 module.
1536 SGML reader parses comments and makes them part of the data1 tree.
1538 Added several type casts so that YAZ compiles as C++ code.
1540 ZOOM didn't handle PDU encoding failures properly.
1542 Added more Bib-1 diagnostics (approved extensions).
1544 GNU configure: better check for iconv.
1546 More portable use of accept, getpeername. Check for socklen_t. Use
1547 int/size_t if socklen_t is not defined.
1551 PQF parser rejects bad queries - including those with extra
1552 characters in them. PQF parser used to silently ignore that.
1553 Cleaner API for PQF added, which allows you to get detailed
1554 error information for bad queries (see yaz/pquery.h).
1556 Fixed bug in ZOOM_record_get for type "database".
1558 Implemented mini iconv library supporting conversions between
1559 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1561 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1563 --- 1.8.9 2002/08/20
1565 Fixed ZOOM C record cache so that preferredRecordSyntax and
1566 elementSetName is used to check for already fetched records.
1568 --- 1.8.8 2002/08/02
1570 Added three members in bend_initrequest structure to facilitate
1571 character set negotiation.
1573 Fixed a bug in frontend server that could cause indefinite
1574 loops under rare conditions.
1576 Revised character set utilities (charneg.h) so that encoding
1577 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1579 For PQF, directive @term <type> sets term type for Scan/Search.
1580 Here <type> is general, string, numeric, null. The term type
1581 is inherited - just like @attr.
1583 New call odr_set_charset that sets character set conversion for
1584 international-strings on a ODR stream. Prototype is:
1585 int odr_set_charset(ODR o, const char *to, const char *from);
1586 The InternationalString is still represented as C string in YAZ
1587 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1588 won't). On the protocol level, you can use any encoding.
1590 Support for UNIX sockets in ZOOM.
1592 Solaris recv sometimes returns errno == ENOENT. It is treated as
1593 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1595 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1596 both client and server. Code by Morten Bøgeskov.
1598 --- 1.8.7 2002/05/22
1600 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1601 that they can be used directly from Visual Basic. You must recompile
1602 your windows APP if you're using ZOOM.
1604 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1605 Commands "lang" and "charset" sets language and character set respectively.
1606 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1607 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1609 Attributes from multiple CCL fields may be OR'ed rather than merged
1610 using directive "@field or". Fields are still merged by default -
1611 equivalent to "@field merge".
1613 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1616 Fixed bug in zget for parameter ExtendedServicesResponse.
1620 --- 1.8.6 2002/03/25
1622 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1624 Client displays USR.1:SearchResult-1 (hits per term).
1626 Additional Search Info for search in Generic Frontend Server.
1628 Fixed CCL parsing of "field=s".
1630 WIN32 installer - using the excellent NSIS software from nullsoft.
1632 Fixed CCL parsing of "field = - <number>".
1634 Added function yaz_marc_decode that decodes MARC for line mode
1635 display or XML (similar to that used by JZKit).
1637 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1638 Z39.50. But ISO/ILL was, however.
1640 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1641 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1643 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1644 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1646 --- 1.8.5 2002/02/03
1648 New YAZ client features: Command completion and new commands:
1649 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1650 Code provided by Jacob Poulsen.
1652 New call oid_trav, that visits all registered OIDs via callback.
1654 Function ZOOM_record_get now returns const char pointer rather than
1655 void pointer. It saves a lot of type casts.
1657 For YAZ client, command "auth" now allows you to set authentication
1658 in IdPass style. It is enabled when three tokens are given - order
1659 is user, group and password.
1661 Fix memory leaks in MARC record handling for ZOOM.
1663 New option for YAZ client, -k <kilobytes> that sets
1664 maximum record size. Similar to -k option for generic frontend
1665 server and yaz-ztest.
1667 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1669 Prefix query parser reports "fail" when bad attribute set is given.
1671 Fix in MARC decoder. Proximity logging. Fix for attribute set
1672 in scan handler for server. Patches by Shigeru Ishida.
1674 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1677 Configure option --with-openssl=<dir> now works when a directory is
1678 specified. Patch provided by Morten Bøgeskov.
1680 New option for YAZ client, -u <auth>, that sets authentication.
1682 ZOOM fix: error information was sometimes "missing", since error
1683 was cleared/reset too when it shouldn't.
1685 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1687 --- 1.8.4 2002/01/04
1689 Scan for ZOOM API. New object ZOOM_scanset. New functions
1690 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1691 ZOOM_scanset_destroy.
1693 New ZOOM function, ZOOM_connection_last_event, that returns type
1694 of last event (such as "receive data", "send data", "apdu received",
1697 New ZOOM option, schema, that specifies schema for retrieval.
1699 New CCL feature. Qualifiers can be aliases for one or more
1700 other qualifiers (if more than one is given, OR is used).
1702 ZOOM uses named result sets if target supports it.
1704 Two new YAZ client commands: . (dot, which sources a script of YAZ
1705 client commands), and ! (to execute shell command.). Implemented
1708 Working on Debian packages.
1710 --- 1.8.3 2001/11/19
1712 YAZ client enables named result sets only if target supports it.
1714 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1716 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1717 with key="host" to get same result.
1719 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1720 Function Z3950_resultset_record(s) returns references to records
1721 "owned" by resultset. To become owner use Z3950_record_clone.
1723 Function z_ext_record handles Extended Services. Thanks to
1726 --- 1.8.2 2001/11/12
1728 CCL Parser fix: ignore token comma when dealing with and-lists.
1730 Documentation updates for COMSTACK.
1732 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1733 Changed prototype Z3950_records. For some functions, int parameters
1734 were changed to size_t.
1736 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1739 New MARC decode/display function, marc_display_exl, which properly rejects
1740 non-ISO2709 records. YAZ client uses it.
1742 --- 1.8.1 2001/10/29
1744 Fix bug: local attribute set wasn't set correctly in PQF strings.
1748 * Old Z39.50 codecs no longer supported.
1750 Added ZOOM C binding. See http://zoom.z3950.org/
1752 Renamed states for COMSTACKs to avoid confusion with events.
1754 Implemented cs_look and proper cs_rcvconnect.
1756 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1758 Configure detects POSIX threads on OpenBSD.
1760 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1761 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1763 When error is returned from present handler, non-surrogate diagnostic
1764 is returned in present response (and fetch handler is no longer called).
1766 * Minor adjustments to pquery parser (PQF). Token characters may be
1767 escaped by using backslash (C-style).
1769 PQF parser allows string attribute values to be specified. For @attr,
1770 non-numeric characters after the equal-sign are treated as strings
1771 (e.g. @attr 9=title).
1773 CCL trunction character may be defined (@truncation in file)
1775 * function zget_ExtendedServicesRequest sets waitAction to
1776 waitIfPossible (was wait).
1778 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1781 CCL operator names may be set in field definition files (CCL_bibset).
1782 See ccl/bib1 for an example.
1784 Fixes in ASN.1 compiler for C++ compatibility.
1786 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1787 and "op_or" to avoid conflict with C++.
1789 Fixed problem with GNU readline detection on Redhat 7.0.
1791 Added step-size for Scan backend handler.
1793 Fixed bug that made the frontend server crash when no attribute
1794 set was specified for scan.
1796 Front-end server automatically switches to original working directory
1797 when installed as an NT service. Previously -w had to be specified to
1800 Added extended attributes for retrieval module (data1), so that data1
1801 records carry d1_readXML/SGML attributes. d1_read also supports
1802 null-data rules ( <tag/>)
1804 On UNIX when POSIX threads are available, a separate library libyazthread
1805 is created. Programmers should link with that library and the yaz library
1806 when using threads. The reason for the split was that some applications
1807 on Linux, such as Apache, doesn't work well when using shared objects that
1810 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1811 (or any frontend server) in SSL mode by specifying ssl: followed by
1812 address. Only tested on UNIX.
1814 Added feature for CCL module. Virtual structure s=al or s=ol generates
1815 and-list and or-list respectively instead of phrase search.
1819 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1820 log_mask_str. This was done to avoid name conflicts with other libraries
1821 (such as other PHP extensions).
1823 Added raw OID member for preferred record syntax (request_format_raw)
1824 and returned record syntax (output_format_raw) for backend fetch method.
1826 Config file yaz-config now accepts options so that it returns specific
1827 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1829 Shared library support for UNIX using GNU libtool.
1831 * Modified backend interface. Request/Response struct's replaced by
1832 one read/write C struct. For example bend_fetchrequest and
1833 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1834 Every handler - even search has to be registered in bend_init
1835 handler. This means that the YAZ library no longer refers to
1836 external functions and it makes it possible to make the whole
1837 thing a single DLL/SO.
1839 Added Segment handler for backend server.
1841 Added Zmbol/Zebra administrative functions to YAZ client.
1843 Threaded frontend server on UNIX (when POSIX Threads are available).
1844 Starting the server with option -T enables multi-threading.
1848 Added configure option --enable-comp/disable-comp to control use
1849 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1850 located in sub directory asn.
1852 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1853 in ${exec_prefix}/bin along with the other programs yaz-client and
1856 GNU automake used to maintain makefiles.
1858 Added several OID's.
1860 Changed retrieval module so that we can load records with no abstract
1861 syntax defined. Tagpaths in these records are fully composed of string
1864 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1868 On UNIX, the generated makefile now supports a proper 'make install'.
1869 The prefix can be set via GNU configure to set the install location
1870 (default is /usr/local).
1872 * YAZ programs client and ztest were renamed to yaz-client and
1873 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1874 locations, such as /usr/bin,/usr/local/bin,etc.
1876 * YAZ Header files were moved from include to include/yaz. YAZ Header
1877 files are referred to as include <yaz/log.h> rather than <log.h>.
1878 The YAZ include path (-I ..) is therefore the same as before. Programmers
1879 should update their #include statements or use -Ipath/include/yaz
1880 instead. The main motivation for doing this change is that YAZ header files
1881 can be installed in "standard" locations /usr/include,/usr/local/include
1882 without introducing conflicts, since ALL YAZ header files are stored
1883 in subdirectory yaz (under /usr/include for example).
1885 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1886 rather than project/workspace files. We switched because project files
1887 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1890 Changed name of logging function, logf, to yaz_log, to prevent name
1891 clash with some math-log functions. The YAZ header log.h defines logf
1892 to yaz_log (#define) so there should be no incompatibilities by this
1895 Added bend_start/bend_stop handlers for server. These handler are
1896 called on start/stop of server. For windows they are called whenever
1897 a service is started/stopped.
1899 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1900 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1901 in util/yc.tcl. The auto-generated C code structures are, in a few
1902 cases, incompatible with the old decoders. There are differences in the
1903 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1904 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1905 The preprocessor variable ASN_COMPILED is defined when the compiled
1906 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1907 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1908 wish to use the old encoders/decoders you can specify --disable-yc
1911 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1912 version so that it supports both new - and old version of DB Update
1914 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1915 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1916 change. The name parameter can be set to 0 in which no name is specified
1917 for the construction. The macros odr_implicit and odr_explicit sets name
1918 parameter to zero for the construction involved. New macros
1919 odr_implicit_tag and odr_explicit_tag are similar to the others,
1920 except that a name parameter is added. For programmers' that don't use
1921 ODR they probably only need to change the call to z_APDU and z_External.
1923 Added access control facility by interfacing the TCP wrapper library.
1924 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1925 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1926 name of the daemon and enables the access control as specified in
1927 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1929 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1930 den Dool <H.M.vdnDool@kub.nl>.
1932 Added reference ID parameter to most functions in server API - refer
1933 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1935 Changed name of ccl library to libccl.a (was ccl.a).
1937 Fixed bug in decoder for Explain (Category TargetInfo).
1939 Added support for GNU readline in client. Thanks to Jacob Poulsen
1940 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1942 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1943 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1944 IMPLEMENTATION! This change was made to the development version before
1945 the ZIG decided to retract the amendment. If any users MUST be
1946 compatible with the original Update definition, PLEASE CONTACT US, and
1947 we will include a separate definition corresponding to the old Update
1948 ES. Note that because of the change to the ASN.1 of the
1949 TaskPackageRecordStructure we cannot define a single structure that
1950 will support both versions.
1952 * Added const modifier to buffer parameter for some ODR/BER encoding
1953 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1954 completeWAIS, odr_dumpBER.
1956 Fixed bug in client.c which caused a crash when a scanResponse didn't
1957 contain positionOfTerm.
1959 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1960 * will cause an error in a client if a non-YAZ target sends both a
1961 * list of Scan entries and non-surrogate diagnostics.
1963 Retrieval module enhancements. Tag sets may be typed in the reference
1964 to it. From the .abs-file the "tagset" directive takes a third optional
1965 integer type for the tag set referenced. From a .tag-file the "include"
1966 directive takes a third optional type as well. The old "type" directive
1967 in the tag set itself is still recognized but acts as the default type
1970 Backend interface change. Individual Scan terms returned from bend_scan
1971 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1972 in include/backend.h.
1974 Retrieval module enhancements. Multiple tag sets and attribute sets may
1975 be specified in abstract syntax specs. Revised the error/warning for
1976 logging messages reported by the retrieval module when reading the
1979 Object Identifier system (oid_..) changed. The API is backwards
1980 compatible but the oid-routines now allocates new OID's when needed.
1981 Raw OID's may be specified in oid_getvalbyname.
1983 YAZ now uses GNU configure to generate Makefile(s).
1985 * Minor changes in some of the member names of DeleteResultSetRequest and
1986 DeleteResultSetResponse. See include/proto.h.
1988 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1989 and added member 'languages' in TargetInfo (which was missing).
1991 Changed the way attribute sets are handled in the retrieval
1992 module. These are now cached, just like the abstract syntaxes
1995 Changed YAZ so that it links with compiled ASN.1.
1997 Added Explain-schema definitions and mapping routines. The following
1998 Explain categories have been implemented: AttributeDetails,
1999 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2001 Fixed minor bug in Windows version of Server Library.
2003 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2005 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2007 Added EXTERNAL: UNIverse Resource Report (non-standard).
2009 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2010 ENUMERATED and SET OF.
2012 * Added 'const' to some of the char pointer arguments for the
2013 functions, data1_read_node, data1_getelementbytagname,
2014 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2017 Fixed bug in data1_insert_taggeddata - the last_child member of
2018 parent wasn't initialised.
2020 * Changed data1_read_record and data1_read_node so that the supplied
2021 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2022 doesn't refer to any parts of the "SGML"-buffer.
2024 Fixed bug in server library (Windows version of statserv_remove).
2026 * Changed code so that it compiles as C++. The type definition
2027 of Odr_fun which is a member of Odr_arm was changed. The result is,
2028 that an explicit typecast is needed for the fun pointer when
2029 using Odr_arm - as in:
2030 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2032 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2034 Implemented the new structured date and time definition as approved
2035 by the ZIG. Added schemaId element to the specificTag in Espec-1
2036 (also approved at the last ZIG). Thanks to RVDM.
2038 Added some Object identifiers (RVDM).
2040 Changed the Update Extended Service (RVDM).
2042 Added command "refid" to client which specifies referenceId for
2043 the following requests.
2045 Implemented extended service handling for server. See ztest.c
2046 for an example as well as backend.h. New handlers are registerd
2047 in the Init handler.
2049 * Changed interface for sort in server.
2051 Added new members to statserv_options_block. It allows a server
2052 to read options from another source than just the command line. Thanks
2053 to Charles Woodfield.
2055 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2056 renamed to zboolean. Some C++ compilers complained about the name.
2058 Minor changes to gils.abs. Added index 's' (sort) on title
2059 and date/time-last-modified.
2061 --- 1.4pl2 1998/1/30
2063 Fixed bug in server library regarding inetd mode (-i). This bug
2064 was introduced by release 1.4.
2066 --- 1.4pl1 1998/1/29
2068 Added sort facility in client and backend server interface.
2070 Fixed problem with dependencies in Makefile(s).
2072 Fixed bugs for encoders/decoders of extended services and
2075 Implemented sub-tree feature for schemas. Sub-trees are
2076 referenced in *.abs-files. See explain.abs for an example
2077 of the use of this feature.
2079 Modified bib1.att; local attributes for ANY didn't include
2080 ANY itself (only affects use of the retrieval module).
2082 Fixed bug in plain SGML reader in function data1_read_node:
2083 tags with prefix "var" was incorrectly interpreted as variants.
2085 Added feature "sub-schemas" to enable references to - and definitions
2086 of - group of elements.
2088 * Removed member parent from type data1_element (in data1.h).
2090 Implemented function odr_nullval() that returns the value of
2093 * Removed member num_children from data1_node (in data1.h).
2095 Made NT service interface part of the server library. The
2096 function statserv_main uses the NT service when required and
2097 calls the statserv_start / statserv_close routines.
2099 Routine zget_SearchRequest and zget_PresentRequest fills
2100 resultSetName/Id member with "default" instead of "Default".
2102 Fixed memory leak in server. Request queue member wasn't freed.
2104 Fixed nmem_exit so that memory is freed.
2108 Revised the CCL parser utility to be thread safe.
2110 Added function, oid_ent_to_oid, to replace the function
2111 oid_getoidbyent, which is not thread safe.
2113 * Added nmem_init and nmem_exit to initialize and release
2114 NMEM resources. Function nmem_init should be called once in the
2115 initial thread before NMEM/ODR is used. statserv.c and client.c
2116 have been changed accordingly. The change was necessary to make
2117 NMEM thread safe. The NMEM memory pool is shared amongst threads
2118 in a process. Unix-based applications will still work fine without
2121 Added NT Services interface for the the Z39.50 (statserv) Server.
2122 Refer to the ztest.c source on the usage.
2124 Windows 95/NT port using MSVC5.0. Project files are included in the
2127 * Defined new 'global' handle for the retrieval (data1) system. The
2128 new handled, data1_handle, describes the state of the data1 system.
2129 This handle is passed as first argument to virtually all
2130 data1 related routines. The functions data1_create and data1_destroy
2131 creates and destroys a data1 handle respectively.
2133 Added ODR encode stream member to all backend request structures
2134 init, search, scan etc. This stream should be used to allocate all
2135 memory used for the response when thread safe operation is needed.
2137 Changed the comstack utility, cs_addstr, to be thread safe. The
2138 returned hostname string returned by the function is now part the
2141 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2142 function. The cs_straddr takes a COMSTACK handle as argument, so this
2143 function must be used after cs_create and before bind/connect.
2144 This function is thread safe.
2146 Moved test server to 'ztest' directory - generic server code still
2147 in 'server' directory.
2149 Made prefix query (pquery.c) utility thread safe.
2151 Added new function modifier YAZ_EXPORT to 'export' public DLL
2152 functions when using windows (see include/yconfig.h).
2154 Added definitions to the OID database (util/oid.c) (RVDM).
2156 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2158 Added call to ccl_rpn_delete in client program.
2160 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2161 release of RPN structure.
2163 Added support for C++, headers uses extern "C" for public definitions.
2164 With input from RVDM.
2166 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2167 Thanks to Ronald van der Meer (RVDM).
2169 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2171 Added support for private extensions to the OID database
2172 (oid_setprivateoids()). Thanks to RVDM.
2174 Added optional, physical ANY (key replication)
2176 Fixed null-reference problem in GRS-1 output filter.
2178 Proximity operator added to Prefix Query Format (PQF).
2180 In test client command "base" accepts multiple databases.
2182 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2186 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2188 Smallish bug-fixes in the new encoders/decoders (explain).
2190 Bug fixed in DeleteRequest.
2192 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2194 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2196 Added SOIF syntax (using private OID for now) to retrieval module and client.
2198 Added Update extended service.
2200 Added SearchResult-1 additional info structure.
2202 Added optional CCL (ISO8777) interpreter as separate module. Available
2205 --- 1.2 1996/6/10 (1st anniversary release)
2207 Added Summary record syntax. Lightly tested.
2209 Added OPAC record syntax. Untested.
2211 Added ResourceReport service encoders/decoders. Untested.
2213 Fixed bug in z_Unit - wrong tagging on unitSystem.
2215 Fixed bug in the DiagRecs decoder.
2217 Added options for max PDU size and session timeout to frontend-server.
2219 Added documentation of query-language parsers and other supporting utilities.
2221 [frontend-server] Added Attribute set to the bend_scanrequest API.
2223 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2224 surrogate diagnostics were generated.
2226 [retrieval] Allow multiple local values for attribute.
2228 [retrieval] Allow multiple attributes per element in .abs files. index type.
2230 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2232 --- 1.1pl2 1996/4/10
2234 Minor changes, mostly specific to Zebra's requirements (retrieval)
2238 Repaired bug in frontend server when running multiple listening
2239 endpoints in dynamic mode.
2241 z_External() now won't break if a known, ASN.1 value comes encapsulated
2242 in an octet-string. The value will pass through unmodified in an Odr_oct.
2244 Added a bit of code to the demo client to decode & display
2245 ASN.1-structured records represented in the octet-aligned branch of
2246 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2248 Added z_ext_getentbyref() to the ASN module. Doc updated.
2250 * Completed the SCAN definition in the ASN module. This may break SCAN
2251 code based on older YAZ-versions at compile-time. The fix is easy -
2254 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2255 under the SCAN definition. Remember to initialize this, server-people.
2257 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2258 that this does not extend to ODR and ASN.
2260 Comstack allows insertion of established socket (primarily for
2261 inetd-operation of servers). Doc updated.
2263 Front-end server can now start from the inetd in TCP mode. Doc
2266 --- 1.0pl4 1996/1/24
2270 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2271 the rank and record number.
2273 Adjustments to the frontend server.
2275 Fixed diagnostic BER dumper. It ignored the file argument.
2279 Various changes to retrieval module.
2281 Changed the union discriminators of the protocol files from enums to
2282 ints paired with #defines.
2284 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2287 *Changed operator in the RPN structure to 'roperator', again to avoid a
2290 Fixed problems in Explain decoders/encoders.
2292 --- 1.0pl2 1995/12/6
2294 Memory bug in log module fixed.
2296 --- 1.0pl1 1995/12/5
2298 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2300 Bug in Explain DatabaseInfo module fixed.
2302 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2306 The shift to v1.0 signals that we now consider the *core* functionality
2307 of YAZ reasonably stable (the core being more or less equivalent to
2308 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2309 tested (Explain not at all - though that will happen soonish).
2311 Minor changes to code to support Windows port.
2313 Various minor changes after we're getting to use GRS-1 & co. more.
2315 Added Espec-1 format.
2317 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2318 of the protocol and it cannot be selected when encoding (maps into 'string'
2319 when decoding). Needed to talk to some servers.
2321 Demo client can request simple element set names.
2323 Added Diagnostic Format encoders/decoders.
2325 Added simple Close handling to frontend server (no hooks for resource
2326 reporting yet), and demonstration client.
2328 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2330 --- 1.0b3 1995/08/24
2332 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2333 handled incorrectly when records were requested in the searchResponse. This
2334 will only affect you if you use the frontend-server.
2336 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2337 Test-client will ask for and print GRS1. Ztest will return dummy records
2340 Added Explain encoders/decoders to the service-level API. Untested.
2342 Added Extended Services: Item Order encoders and decoders to the Service-
2343 level API. Untested. We could use a recent copy of the pertinent bits
2344 of the ILL protocol to add those bits.
2346 Added diagnostic format 1 encoders/decoders to the service-level API.
2349 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2350 odr_cons.c, which causes a more correct output.
2352 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2353 was always set to 0 when no records were requested in the searchRequest.
2355 * Added better external-handling. This shouldn't harm old code that
2356 *encodes* externals. It can break code that looks for a
2357 'single-ASN1-type' representation, since those types that are known
2358 are now decoded immediately. Look at the SUTRS sample code in
2359 seshigh.c and client.c. Documentation updated.
2361 Handling of structured records in bend_fetchresponse. Length -1 marks
2362 structured record, type is deduced from format field.
2364 --- 1.0b2 1995/06/27
2365 Fairly quick maintenance release to add SUTRS support.
2367 Fixed handling of SUTRS records in the demonstration client.
2369 * Added format field to the bend_fetchrequest and bend_fetchresponce
2370 structures of the backend API (frontend server). When the record is
2371 returned, the value of the format field is mapped to an OID. The
2372 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2373 of the record. The special value VAL_NONE in the bend_request means
2374 that no specific format was requested by the client. Documentation
2375 updated accordingly. Test server (ztest) will return a fixed dummy
2376 SUTRS record if your client requests SUTRS.
2378 Documentation updated accordingly.
2380 You can now set external libraries and RANLIB support in the top-level
2384 First public release.
