1 yaz-ztest returns OPAC records if a client asks for OPAC.
3 Improved speed of MARC-8 encoding.
5 Added support for lossy and loss-less MARC-8 encoding.
7 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
9 Added new Windows Service wrapper (sc).
11 yaz-client's itemorder command may now send a file.
13 Fixed yaz-marcdump to allow the use of NS prefix for record element.
15 Added new function yaz_log_xml_errors.
17 Allow (but warn) unknown XML attributes in MARCXML parsing.
19 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
21 The UTF-8 to MARC-8 conversion now uses a different set of characters
22 for Greek symbols. Bug #2120.
26 Added yaz_daemon (daemon.h).
28 Fixed bug #2068: pkg-config trouble
30 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
34 Document --with-xml2 option.
36 Added OPAC XML XSD (etc/opacxml.xsd).
38 Allow glob mask for name attribute in retrieval element for the
39 generic frontend server's retrieval facility.
41 Changed yaz_poll_poll to return yaz_poll_except for all returned events
42 except POLLIN/POLLOUT.
44 Fixed error handling in cs_listen. Bug #2037.
48 Fixed version in yaz/yaz-version.h.
50 Fixed bug #2027: Crash when closing connection.
52 Changed configure so that ICU support is only enabled if only ICU
53 and Libxml2 is available (because the ICU chain is XML based).
57 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
58 is built. Only this DLL depends on the ICU runtime.
60 yaz-ziffy is no longer part of YAZ. It is distributed separately by
61 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
63 Changed license of CCL module to 'Revised BSD'. After consultation with
64 remaining members of the original EUROPAGATE consortium, we are re-issuing
65 the CCL module without a separate license. The software was developed by
66 Index Data as part of a research project. The special license was included
67 to help feed usage information back to the project consortium to support
68 project evaluation. At this time, the project consortium has long-since
69 disbanded, and the majority of the original principals have retired. At the
70 same time, we have significantly modified the software during the following
71 years, to the point where very practically no original code remains. To
72 simplify re-use of the software, we have contacted those members of the
73 consortium who could be reached, and agreed to re-issue the module as a
74 proper part of the YAZ package.
76 Tcl scripts uses /usr/bin/tclsh as preferred shell.
78 CQL closer to being version 1.2 compliant. CQL also allows free-form
79 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
82 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
83 bug could make Extended services handling crash in the ZOOM layer. This
84 bug was only present in YAZ 3.0.18.
88 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
91 yaz-marcdump reads and writes collection wrapped records.
93 Handle OPAC for record conversion module.
95 Fixes for ICU wrapper.
97 Allow ICU libs to be controlled with --with-icu .
101 Added yaz_poll which is a wrapper for select/poll. When poll is available
102 and non-buggy, it is used, by yaz_poll . This allows more than 1024
103 sockets to be in use.
105 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
106 functionality through an XML based configuration (ICU chain). This system
107 is useful for search facilities such as Pazpar2 and Zebra that needs to
108 perform tokenization of indexed material. The ICU code in a separate
109 library libyaz3_icu.a.
111 Added HTTP tunnel facility for COMSTACK, bug #1752.
112 This is a facility that allows a Web proxy, such as squid, to tunnel
113 Z39.50 traffic. This facility is "transparent" to must applications
114 using YAZ. It's enabled by using pseudo transport connect: followed by
115 the proxy address, followed by command, then follwed by he regular
116 "virtual" addresss. For example,
117 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
119 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
121 --- 3.0.14 2007/09/21
123 Fixed bad memory reference in ZOOM_record - cuased by member not being
124 initialized. This was a problem only in YAZ 3.0.12.
126 Fixed bug in conversion from MARC to XML: Non-XML characters in control
127 fields were not removed.
129 Changed the way C code is generated from codetables.xml. Made a MARC-8
130 conversion trie for each characterSet section rather than codeTable.
131 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
132 of codetables.xml from Larry Dixson, LOC. Bug #1464.
134 --- 3.0.12 2007/09/12
136 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
137 from ZOOM_record_error).
139 ZOOM C function ZOOM_record_get returns record schema for type="schema".
141 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
143 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
145 Better SRW-to-Bib-1 diagnostic mapping.
147 ZOOM C and yaz-client announces SRU version 1.2 by default.
149 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
152 Fixed in yaz_sru_decode to allow other version than 1.1.
154 --- 3.0.10 2007/08/22
156 Added support for SRU scan for ZOOM.
158 Added support for the use of the older versions or Extended Service
159 Update in ZOOM. To faciliate this, an option "updateVersion" may be
160 set to the version , 1=first, 2=second, 3=third. The third version is
161 what ZOOM C has used so far. And that, obviously, is the default.
163 Added support for CCL queries in Z39.50 queries sent to the GFS (and
164 therefore in Zebra and in SimpleServer-based applications). The new
165 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
166 qualifier file used to transform incoming CCL queries into Type-1 RPN,
167 which is passed into the back-end search callback function.
169 Added support for HTTP Basic authentication in clients: the SRU/W
170 codec encodes the username/password elements of the PDU structure
171 appropriately, and these may be set using the "user" and "password"
172 options in ZOOM-C applications (the same options that are used for
173 Z39.50 authentication).
177 Fixed bug #1208: SSL appears to be broken in ZOOM.
179 Fixed bug #1206: Libxml2 include path weirdness.
181 Added oid_name_to_dotstring.
183 Allow elementSetName to be specified for ZOOM C record update.
185 Allow waitAction to be specified for ZOOM C based for Extended Services.
187 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
188 syntax OID. Bug introduced in YAZ 3 series.
190 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
194 Fixed bug #1157: yaz-client does not read .yazclientrc from current
195 directory. yaz-client now reads commands from file given by option -f
196 if specified; then tries to read .yazclientrc in current directory.
197 Failing that, it reads .yazclientrc from user's home directory.
199 Added support for correlationInfo Note and ID for Record Update via
202 Added yaz-client command querycharset which specifies character set for
203 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
204 (termListAndStartPoint).
206 Charset ISO5428:1984 is an alias for ISO5428-1984.
208 Implemented a way to perform scan in a result set using Z39.50. This
209 is achieved by attaching the result set name in the characterInfo
210 (type InternationalString) of OtherInformation in the Scan Request PDU.
211 The result set is identified in the otherinformation by the new OID:
212 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
213 This allows for scan in result set and faceted search . Zebra did some
214 of this in the APT term using attribute type 8 and value being result
215 set. Using the OtherInformation approach for this is cleaner and easier
216 to work with in proxies and the like. This facility can be used in
217 yaz-client using new command setscan which takes a result set as first
218 argument, start position (APT) as second.
220 Changed decoding of SRU XML packed records to deal with servers that
221 have recordData with XML data with multiple root nodes. Also make
222 comparison for recordPacking case insensitive. Again, one server
223 returns "XML" where others return "xml".
225 For SRU responses allow Content-Type application/xml as well as text/xml.
229 Fixed bug in character set conversion of BER strings. Bug introduced
234 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
236 For OID class, use oid_class consistently.
238 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
241 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
242 character set for bibliographic information interchange". By Giannis Kosmas.
244 Added documentation on new OID API.
248 Changes to generic frontend server interface: added new member
249 'query_charset' for bend_initrequest structure. A backend init handler
250 should set this member to its native character set for query terms.
251 When defined, the frontend server logic will announce this character set
252 to a client if the negotiationModel bit is set by the client. All server
253 implementors are encouraged to specify this. If a backend server does not
254 specify this a warning is issued using yaz_log(YLOG_WARN,..).
256 Added CCL utility to remove terms (stop words) from resulting RPN
257 tree. This is handled by functions with prefix ccl_stop_words_ .
259 New ZOOM C option, "rpnCharset", which allows client-side conversion of
260 terms in RPN queries.
262 Clean-up the CCL API. Moved some internal structures from ccl.h to
263 private header cclp.h. Changed ccl_parser_create so that a Bibset must
264 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
265 This is replaced by ccl_parser_find_str which takes a string instead.
267 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
268 libyaz.la is the core of YAZ except the generic frontend server and
269 does not depend on POSIX threads anymore. libyaz_server.la is the
270 generic frontend server facilities and uses POSIX thread functionality
271 if available. The libyaz.la no longer depends on POSIX threads because
272 the number of global structures is limited. NMEM no longer re-uses blocks
273 between threads ; it simply free's memory immediately but allocates in
274 "large" chunks as usual. We don't expect any performance penalties
275 because of this. The yaz_log system is still using a global log_level so
276 caution must be taken when modifying it with yaz_log_init_.. +
277 yaz_log_mask_str. This, however, should not cause any trouble because
278 these functions are called during initialization of application code
279 anyway. `yaz-config --libs server` returns libs for server applications;
280 `yaz-config --libs` returns libs for non-server applications.
282 New OID database - with public definitions in oid_db.h. Removed old OID
283 database including the head oid.h and definitions such as enum oid_value
284 and struct oident. The new OID database uses the same string names as
285 before but the 'protocol' is gone. There are now only two representations
286 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
287 converts from string to OID; functions with prefix yaz_oid_to_string
288 converts the other way.
290 Change to emit_term() in CQL-to-PQF query translation: when a term has
291 the /regexp relation modifier, do not process it for leading and
292 trailing "^" and "*", which have quite different meanings in regular
295 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
296 write handlers no longer carries a 'last' parameter. This will make
297 yaz_iconv flush "less" characters. A flush is performed by call to
298 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
300 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
301 removed, because function yaz_query_to_wrbuf does the same.
303 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
304 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
306 Deprecated MARC utility functions removed.
308 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
311 Branch split: YAZ_2_1_55_branch
313 --- 2.1.54 2007/03/16
315 Fix to ZOOM-C so that transparent reconnection is properly handled on
316 connections that are in asynchronous mode.
318 Fixed compilation on OpenBSD 4.0.
320 Large strings in GRS-1 records are now properly displayed in yaz-client.
322 Added character conversion support for "advancegreek"; based on patch from
325 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
326 sequence is met. Before the error was not set so it would be unknown.
328 Adjust yaz-marcdump MARC reader so that it skips until record separator
331 --- 2.1.52 2007/03/07
333 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
334 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
335 fd_set structure used as a bitmask for the FDs to be selected on.
337 Using ACX_PTHREAD macro to check for POSIX threads.
339 Fixed have-vsnprintf check.
341 --- 2.1.50 2007/02/23
343 Fixes for configure on BSD. Bug #900.
345 Added snprintf/vsnprintf wrappers for systems that don't have
346 limits (heavens forbid).
348 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
349 created before all previous tasks were completed and removed from the
350 task queue, the new task could be removed by a mistake.
352 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
354 Implemented pass-through CQL-to-PQF conversions. Bug #861.
356 Fixed bug #832: Problem with MARC/charset in yaz-client.
358 Fixed bug #668: save command line history for yaz-client.
360 Fixed bug #830: pkg-config support.
362 --- 2.1.48 2007/01/23
364 Extended ZOOM result set options with two options that may be read by
365 a client: resultSetStatus and presentStatus with values as specified for
367 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
369 Fixed bug #827: Using SSL fails on Debian etch.
371 Fixed bug #826: Weird looking chars for set of MARC records.
373 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
374 that is treated as an ItemOrder with itemRequest being an XML document
375 external. The value of "doc" is the content.
377 Extended the GFS search facility. New member of bend_search_rr
378 'estimated_hit_count' signals that hits is known to be an estmate
379 (higher or lower than real hit count). New member 'partial_resultset'
380 signals that the search was partial (hit count is lower or equal than
381 real hit count). For Z39.50, the information is stored in resultSetStatus
382 member of SearchResponse APDU. For SRU, the information is signalled
383 via SRU diagnostic 59: "Result set created with valid partial results
386 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
388 --- 2.1.46 2007/01/13
390 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
392 Added ZOOM_connection_peek_event.
394 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
395 the following new functions:
396 ZOOM_event_nonblock, ZOOM_connection_process,
397 ZOOM_connection_get_{socket,mask,timeout},
398 ZOOM_connection_fire_event_{timeout,socket}.
399 The existing blocking event handler, ZOOM_event, is a wrapper for the
400 + blocking ZOOM_event_sys_{poll,select}.
402 Implemented function ccl_xml_config which parses XML version of CCL
403 configuration (bug #798).
405 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
407 Added timings utility (yaz/timing.h)
409 --- 2.1.44 2007/01/03
411 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
414 Fixed bug #779: Rotation of apdu.log fails.
416 Fixed for character set conversions:
417 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
418 Honor G1 set in MARC-8 decoding.
420 --- 2.1.42 2006/12/17
422 Fixed bug #775: char conversion does not handle Alternative UTF-8
425 Implemented function yaz_marc_read_line which parses MARC line format
426 records. There is a wealth of formats out there. So far, this function
427 reads line records produced by yaz_marc_write_line.
429 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
430 more generic and easier to remember(!) options: -i format and -o format
431 which specifies input format and output format respectively - where
432 format is one of "marc", "marcxml", "line", "marcxchange".
434 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
435 does not print anything except warnings for records.
437 For yaz-marcdump, added support for MARC split into files (-s) with a given
440 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
441 spec, at http://www.loc.gov/standards/sru/record-update/
442 This has changed the binary layout of the following structs:
443 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
444 bend_update_rr . Patch by Ko van der Sloot.
446 Added GFS utility function bend_assoc_is_alive which returns 1 if
447 association is still alive (client is connected); 0 otherwise (client
448 closed connection). This allows busy servers to stop working for
451 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
452 been a separate piece of software. This version of ziffy has been modified
453 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
455 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
457 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
458 Client code may now interrogate options such as "init_opt_sort" to
459 find out whether the server claims to support various options.
461 --- 2.1.40 2006/11/27
463 Added utilities yaz_{set,get}_esn to set/get element set name from
466 Removed the build of libyazthread.la. The libyaz.so is the threaded version
467 of YAZ and has been so since YAZ 2.1.10.
469 Implemented ZOOM_record_error which returns error information for
470 record (surrogate diagnostic).
472 --- 2.1.38 2006/10/31
474 Updates for SRU Update by Ko van der Sloot:
475 1. Changed name from "operation" to "action"
476 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
477 versions in the code, marked as 'backward compatible'.
478 3. Added diagnostics for SRU Update.
480 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
482 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
484 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
486 For GFS, fixed problem with SRU diagnostic 'First record position out of
487 range' being issued for 0 hits.
489 zoomtst10 part of Windows Build.
491 --- 2.1.36 2006/10/13
493 Implemented yaz_filepath_comp which splits a path into file path
494 components (required by Zebra 2.0.3+).
496 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
497 BSD inspired license until now so this should not have any real impact on
498 anybody. See http://www.opensource.org/licenses/bsd-license.php
500 Fixed bug #687: Missing log lines.
502 Fixed bug #678: CQL to PQF translation does not preserve double-quote
505 Fixed bug #689: SRU diagnostics to be added.
507 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
508 whether a connection is idle (no more work do do).
510 --- 2.1.34 2006/10/04
512 Change type of optval from long to int for invocation of setsockopt with
513 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
515 Added support for specifying the max log file size for the Generic
516 Frontend Server. The size is given with option -r.
518 --- 2.1.32 2006/09/21
520 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
522 --- 2.1.30 2006/09/17
524 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
527 Fixed bug in Generic Frontend Server that could cause a server to stop
528 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
530 For the generic frontend server, the maximum record size is used as maximum
531 size of incoming packages (SRU + Z39.50). The value until was previously
532 only used in Z39.50 Init negotiation and, later, in a session controlled
533 sizes of records returned. This is controlled using -k option. It can be
534 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
536 --- 2.1.28 2006/09/04
538 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
541 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
543 New option for yaz-marcdump -lpos=value which allows setting a portion
544 of MARC header to a certain value.
546 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
548 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
549 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
551 --- 2.1.26 2006/08/15
553 Fixed problem with SRU mode type (soap, get, post) for yaz-client
556 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
558 --- 2.1.24 2006/08/08
560 Fixed MARC ISO2709 encoding routines to deal with character set
563 Minor changes to GFS logging. Database included in search request log
566 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
567 cached/multiple records.
569 Shared libraries are built by default on Unix+configure.
571 Changed cql2pqf transformation to use a different evaluation order. The
572 new order is: always, relation, structure, position, truncation, index
573 and relationModifier. Old order was: always, relation, relationModifier,
574 structure, index, position, truncation. Note that the the latter ones
575 override former ones for identical attributes.. The new scheme means that
576 it is possible to override any existing attribute with a relationModifier.
577 And also that it is possible to override everything for the index rule
578 (except the ones listed in relationModifier). No order is perfect but this
579 one, we believe, covers more real cases.. The "always" should have been
580 called "default", since the attributes there can be overridden with all
583 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
584 compilation phase, but also for yaz-config --cflags output. This allows
585 us to have public headers with Libxml2 stuff in them . It should also,
586 eventually, make Libxml2 checks redundant in packages using YAZ, such
589 --- 2.1.22 2006/06/15
591 Changed SRU update structure bend_update_rr so that SRU diagnostics are
592 stored in uri, message and details.. Previously diagnostics were stored
593 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
594 compatibility.. but he's probably the only one affected, so.
596 Added support for CCL, compiled on the client side, in ZOOM-C. This
597 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
598 input; the resulting query objects can be used for for searching with
599 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
601 YAZ' configure searches for OpenSSL by default.
603 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
604 SL_CTX_use_certificate_file. See
605 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
606 for more info. Thanks to Ko van der Sloot.
608 --- 2.1.20 2006/06/02
610 Bug #600: SRU GET, POST support for yaz-client. Introduced
611 command 'sru' which selects method SOAP/GET/POST.
613 Allow missingValueAction to be specified for the sortspec string -
614 function yaz_sort_spec. By default, the missing value action is null.
615 Use ! to specify "abort". Use = followed by stringvalue to specify default
618 Ensured that Present-handler (if defined) is called in GFS before any call to
619 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
620 searchRetrieve requests.
622 Documentation for YAZ is now based on the Docbook XML/XSLT using
623 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
624 is no longer depending on jade/openjade or docbook-to-man scripts.
625 PDF is no longer part of the distribution - but can optionally be
626 made using DSSSL/jadetex or FOP.
628 Added retrieval handling support in Generic Frontend Server to support
629 conversion between MARC/XML as well as XSLTtransforms. See
630 etc/yazgfs.xml for an example.
632 Added Authentication support to Generic Frontend Server in SRU
633 mode. Authentication using HTTP Basic is supported, as is the use
634 of 'x-username' and 'x-password' parameters in the request itself.
636 Added support for a new character set MARC8s identical to MARC8 except
637 that it converts combined characters to single Unicode characters in the
638 Latin-1 range (when possible).
640 --- 2.1.18 2006/04/24
642 ASN.1 compiler 0.4: generates brief Doxygen file header for
643 generated .h/.c files.
645 Utility yaz_iconv now supports conversion to MARC-8.
647 New facilities for the MARC module. The reading - and writing of
648 content are separate methods for the yaz_marc_t handle. The following
649 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
650 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
651 format). Write functions have prefix yaz_marc_write_.. The existing
652 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
653 available. Removed support for OAI-MARC and simplexml (not the
654 simplexml from PHP5).
656 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
657 to be returned for this connection.
659 --- 2.1.16 2006/03/31
661 Allow multiple languages and charsets to be specified with
662 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
663 negcharset iso-8859-1,utf-8
665 Translation of proximity nodes from CQL into PQF now works.
667 Moved to automake 1.8, 1.9.
669 Added function yaz_log_set_handler which allows a log handler to be
670 installed. This handler will be called for all log messages. Output
671 to file is also produced; but that can be disabled by passing NULL
672 fname to yaz_log_init_file.
674 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
676 For SRW (including GFS), accept application/soap+xml as content-type
679 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
680 produces NO stylesheet reference even if a default stylesheet is specified
683 --- 2.1.14 2006/03/14
685 Updated Windows package to include yazd.dll + yazd.lib for the
686 Development component.
688 If the environment variable YAZ_LOG is set, then it is used as a
689 string indicating the default level of logging to use if not
690 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
691 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
692 used as before. So, for example, to omit warnings from YAZ logging,
695 cql_transform() now map structure and other attributes before indexes,
696 so that index-specific structures and other attributes can override
697 defaults. So now a combination of mapping specifications such as:
699 index.dc.date = 1=date-modified 4=5
700 does the right thing.
702 cql_transform() now also respects the "always" mapping specification,
703 which establishes an initial set of attributes to be used for all
704 terms except where overridden by more specific attributes associated
705 with the index, relation or modifier.
707 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
708 which mode to use; one of "post", "get" or "soap" (SRW, default).
710 Fixes for yaz_iconv routines: changed trie-based character set conversions
711 to use only non-negative values for bit fields due to Sun's C compiler not
712 supporting negative values.
714 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
715 sequences where not read correctly. Fix by Rustam Usmanov.
717 Updated win/makefile to use options, settings which makes things
718 compile with VS C 2005.
720 --- 2.1.12 2006/02/01
722 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
724 In ZOOM socket code, use select instead of poll on MacOSX.
726 ZOOM-C now support client-side compilation of CQL into RPN that is
727 sent to the server, enabling CQL to be used against all Z39.50
728 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
729 ZOOM_query object, and submit it using ZOOM_connection_search().
730 The CQL-to-RPN translation uses a configuration file, the name of
731 which must be specified in the Connection's "cqlfile" option.
733 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
734 function, which takes as its start-term parameter a ZOOM_query object
735 (which may have had either CQL or RPN set into it).
738 --- 2.1.10 2005/11/29
740 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
741 GFS to support this as well. Backend handler, bend_srw_update, does the
742 update work. Code contributed by Ko van der Sloot.
744 Allow retrieval of Search Result-1 information in ZOOM by the use of
745 options that are attached to a result set. ZOOM documentation updated
748 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
749 UTF-8 conversion. Patch by Raj Patel.
751 Added option -m to GFS to control formatting of timestamps in log file.
753 Added 'exit' as synonym for 'quit' in yaz-client
755 Added support for specifying SRW resultSetId + resultSetIdleTime in a
756 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
757 for the new members. Patch by Ko van der Sloot.
759 Added support for SRU POST. It is supported for content-type
760 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
762 Do not build the separate Multi-threaded (MT) library libyazthread.la.
763 Instead make the library libyaz.la multi-threaded. Threading as a whole
764 can still be disabled by configure option --disable-threads. Previosly,
765 with older GLIBCs there were problems with MT libs under Apache. This
766 has now been fixed a long time ago.
768 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
771 CQL module modified to be case insensitive for relations/indexes/operations.
773 Fixed bug in CQL transform code: incorrect value relationModifieder
776 Added 'show all' command for yaz-client which retrieves all results
779 Added new yaz-client, xmles, which takes a (private) OID and
780 a document to be sent as an extended service request.
782 Describe new yaz-client commands wait_response and set_auto_wait.
784 Increase TCP/IP listener backlog from 3 (which I am guessing was
785 copied from the SunOS manual entry way back when) so SOMAXCONN, so
786 that the socket will queue as many incoming connections as it's able
787 to handle ongoing connections. In other words, it will never now
788 refuse a connection that it would be able to handle merely because
789 it's not got around to accepting() enough of the pending connections
790 yet. This is the behaviour anyway under Linux, where the listen()
791 argument is ignored; but not under BSD and on systems such as
792 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
793 YAZ-based servers should now be uniform across operating systems in
796 yaz-marcdump uses 64-bit file access on some systems. This is enabled
797 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
798 This allows yaz-marcdump to read large MARC batches (>2 GB).
800 Modified all YAZ source files - except the source which is auto-generated
801 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
804 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
805 corresponding to the existing *_setl() function. These allow option
806 values containing arbitrary valuues.
808 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
809 ZOOM_resultset_sort() in new applications. Its behaviour is identical
810 except that it returns an indicator of whether or not the sort
811 criterion was accepted (0 for OK, -1 for invalid).
815 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
816 MARC output rather than returning "new" buffer.
818 yaz-client warns about unknown init options.
820 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
824 Added support for SRW sort in Generic Frontend Server. Patch
825 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
826 sortKeys - or NULL if none is provided.
828 Fixed bug #307: It was impossible to specify indefinite/no timeout
829 for ZOOM_event. Special timeout value -1 now means indefinite timeout
832 Added support for multiple languages and charsets to be specified in
833 ZOOM. Each charset/language is separated by a blank. If negotiation is
834 in effect in init-response, Option
835 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
836 Code based on patch by Vasiliy Osadchuk.
838 Fixed bug #306: infinite recursion that occurred when calling
839 yaz_log_level_init as the first call (before other log level or
842 Fixed bug in scan handling in front end server: if preferred-Position-In-
843 Response was non-present, a NULL pointer referece was performed.
847 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
848 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
849 now defined for all those error codes. So instead of putting 109 in
850 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
851 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
853 Modified the yaz-marcdump utility to skip garbage bytes between MARC
856 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
858 Program yaz-client now exits and produces an error message if multiple
859 Z39.50 servers are specified on the command line (none or one allowed
862 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
867 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
869 Fixed bug #272: Preserve spacing for CCL terms.
873 Added support for virtual hosts and multiple backend servers for
874 the YAZ frontend server. The configution is XML based and
875 support specificition of CQL to RPN mappings and explain information.
876 See section "Virtual Hosts" in the YAZ manual.
878 Extended OPAC display utility. OPAC display utility renders
879 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
880 to supplement yaz_marc_decode_wrbuf.
882 Fixed a bug in MARC decoder that could caused it to crash for some
883 invalid MARC records. More diagnostics and warnings where added in
884 XML output (warnings, etc are stored in comments).
886 --- 2.0.34 2005/02/08
888 Fixes for UNIX domain sockets. Bug #261.
890 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
892 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
893 Added yaz_marc_subfield_str which defines subfield lead string which is
894 used in YAZ_MARC_LINE format. Default string is blank+$. Added
895 yaz_marc_endline_str which defines end of fields string used in
896 YAZ_MARC_LINE format. Default string is newline.
898 Experimental support for MarcXChange. This format can be produced
899 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
900 http://www.bs.dk/standards/MarcXchange.xsd
902 Added yaz-client commands scansize that sets maximum number of
903 entries to be returned by scan.
905 --- 2.0.32 2005/01/11
907 Added support for SRW scan in yaz-client and Generic Frontend Server.
909 * Added whereInList member to SRW Scan Term.
911 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
913 Fixed NMEM system to return aligned blocks on the smallest boundaries
914 that are suitably aligned for all possible types on the particular
915 architecture YAZ is being built for.
917 --- 2.0.30 2005/01/04
919 Fixed numerious warnings that was issued with newer versions of GCC.
921 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
922 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
925 Make YAZ Generic Frontend Server slightly faster.
927 Enhance (and reduce) logging for Generic Frontend Server.
929 Revert YAZ log system so that it flushes every write operation
930 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
932 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
933 instead of LOG_, due to name clash with syslog(3). LOG_ are still
934 present. New applications should define YAZ_USE_NEW_LOG=1 - this
935 will effectively disable old definitions.
937 --- 2.0.28 2004/11/09
939 Added yaz_log_time_format which specifies log format using
942 Added yaz_log_module_level which returns mask for a module. Value
943 is non-zero mask a if module is enabled; zero if disabled.
945 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
946 in include/yaz/cql.h.
948 Fixed bug #176: Dont throw diagnostics on empty SRU args.
950 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
952 Fixed bug #172: RPM builds does not enable SSL.
954 Doxyfile.in part of dist. Doxyfile generated by configure.
956 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
957 are given and the corresponding component does not exist.
959 Extend CCL documentation in YAZ reference. Describe r=r.
961 --- 2.0.26 2004/10/01
963 Fixed MARC->MARCXML conversion to properly deal with
964 fields, subfields, indicators having non-ASCII characters.
966 Fixed MARC->MARCXML conversion so that ASCII control characters
967 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
970 Added YAZ GFS support for conversion from Z39.50 surrogate
971 diagnostics to SRW surrogate diagnostics.
973 Bug fix: YAZ GFS did not return schema in explainResponse.
975 --- 2.0.25 2004/09/30
977 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
978 now converts recordSchema to elementSetName as well as schema URI.
980 Fixed bug in COMSTACK that prevented HTTP request packages from being
983 --- 2.0.24 2004/09/29
985 Added CCL facility r=r "range" which is similar to r=o "ordered" but
986 does not require white-space before and after the dash in a range, e.g.
987 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
990 Fixed a few AC_TRY_LINK configure tests that did not operate properly
991 due to new GCC removing "redundant" code.
993 Added yaz-client commands scanpos and scanstep that sets preferred
994 position and step-size for scan.
996 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
998 Added CCL utility ccl_qual_buf which parses one or more CCL
999 spec lines in a buffer.
1001 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1002 of name and value - ignoring empty lines and comments.
1004 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1006 Added odr_get_element_path which returns current element path for an
1007 ODR handle. This utility is useful in error handling or user-defined
1010 Added ODR_PRINT utility odr_set_stream which is is a more generic
1011 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1012 to a write function and pointer to close function. The close function - if
1013 non-NULL - will be called during odr_destroy.
1015 Fixed bug in CCL parser where truncation char was not removed from
1016 right side when truncation=both was in effect.
1018 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1021 --- 2.0.23 2004/08/11
1023 Fix buffer overrun in CQL parser when dealing with proximity (%).
1025 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1026 to UTF-8/UCS conversion is now only based on codetables.xml.
1028 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1030 --- 2.0.22 2004/08/06
1032 Add support for more "commit changes" in ZOOM (uses Extended Services).
1034 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1037 Yet another small fix for configure of SSL.
1039 --- 2.0.21 2004/05/14
1041 Fix SSL libs for configure when --with-openssl=DIR is given.
1043 --- 2.0.20 2004/05/10
1045 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1047 SSL comstack now uses yaz.pem certificate file on server side
1048 by default. Certificate filename can be configured by calling
1049 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1051 Fix bug regarding multiple calls to ZOOM_connection_connect.
1053 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1055 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1056 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1058 ZOOM now allows inspection of X509 peer certificate for verification.
1059 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1061 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1062 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1063 as "modular" but it simplifies things.
1065 Added cs_get_peer_certificate to that returns peer X509 PEM.
1067 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1068 NULL if SSL is unavailable.
1070 Documentation about MARC decoding tools.
1072 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1074 --- 2.0.19 2004/03/30
1076 Rename CHANGELOG to NEWS to follow GNU style packing.
1078 Fix bug with missing initialization of member in init_diagnostics.
1079 This bug affects threaded version of GFS server.
1081 --- 2.0.18 2004/03/20
1083 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1086 Ensure zlib.dll is packed with Windows install.
1088 --- 2.0.17 2004/03/17
1090 Fix encoding of xsd:string to use text instead of CDATA.
1092 Fix endless loop in CQL parser with unbalanced ".
1094 Use a more compact way to store MARC-8 conversion tables.
1096 --- 2.0.16 2004/03/16 Debian only
1098 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1101 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1106 --- 2.0.15 2004/03/01
1108 Another fix for decoding of XML packed records.
1110 --- 2.0.14 2004/02/25
1112 Fixes for Chunked encoding. White space not ignored after length spec.
1114 Update NS and use default NS for SRW diagnostic elements.
1116 --- 2.0.13 2004/02/23
1118 Implement ZOOM_resultset_cache_reset which resets record cache.
1120 Implement ZOOM_resultset_sort which sorts a result set.
1122 Implement chunked HTTP transfer.
1124 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1126 --- 2.0.12 2004/02/16
1128 Added member 'schema' to bend_explain_rr structure so that backend
1129 can specify explain record identifier. Defaults to Zeerex 2.0.
1131 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1133 --- 2.0.11 2004/02/16
1135 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1138 Added init command for yaz-client which sends "extra" init request.
1140 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1141 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1143 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1145 Make ZOOM error code for "invalid query".
1147 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1149 --- 2.0.10 2004/02/05
1151 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1154 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1156 Added option -p <file> to make Generic Frontend Server to write PID file.
1158 Added option -D to put Generic Frontend Server in background on its own.
1160 Make ZOOM C recognize option "password". If unset, "pass" is used
1161 (for backwards compatibility).
1163 Fixed a bug in Generic Frontend Server that could make it crash if a
1164 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1167 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1168 Must be issued before open, in order to be in effect.
1170 --- 2.0.9-6 2004/01/12 Debian/Windows
1172 Make the SRU server more picky WRT unknown params, etc.
1174 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1176 New YAZ client command, options, that sets Z39.50 options.
1178 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1179 options from a string of tokens (one token for each option bit).
1181 Update SRW diagnostic code messages.
1183 --- 2.0.9-5 2004/01/07 Debian/Windows
1185 Handle user defined stylesheet for SRW/SRU.
1187 --- 2.0.9-4 2004/01/06 Debian/Windows
1189 Fix bug in decoding of Content-Length.
1191 --- 2.0.9-3 2004/01/06 Debian/Windows
1193 Fix a bug with decoding of XML packed records.
1195 --- 2.0.9-2 2004/01/05 Debian only
1197 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1199 Fix bug in SRW/SRU diagnostics decoding.
1201 --- 2.0.9 2004/01/05
1203 Fixed bug in Generic Frontend Server which could drop records exceeding
1204 preferred message size. Reported and fixed by Irina Dijour.
1206 Fixed calculation of package size for structured records in Generic
1207 Frontend Server. Reported and fixed by Irina Dijour.
1209 Fixed namespace for SRW/SRU diagnostics.
1211 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1213 --- 2.0.8 2003/12/22
1215 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1216 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1219 CQL changes to reflect recent changes to the specification:
1220 * Documentation talks about context sets instead of index sets.
1221 * Documentation talks about indexes instead of qualifiers.
1222 * The CQL-to-PQF transformer's configuration file now uses
1223 "index.set.name = <attributes>" instead of the old form
1224 "qualifier.set.name = <attributes>". (Both forms are still
1225 understood but the latter is deprecated.)
1226 * CQL terms with no explicit index specified are now interpreted as
1227 cql.serverChoice instead of srw.serverChoice (which of course
1228 behaves exactly the same.)
1230 --- 2.0.7 2003/12/16
1232 MARC conversion can now generate ISO2709 output in another
1233 character set. yaz-marcdump uses this facility if you invoke it
1236 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1237 functions from there can be used from C++.
1239 --- 2.0.6 2003/12/04
1241 Frontend server now transfers memory from decoded packages to stream
1244 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1245 references to show up.
1247 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1248 the ZOOM Abstract API. The older names for the same options are still
1249 also supported for the benefit of old applications.
1251 ZOOM-C supports "implementationId" and "implementationVersion" options
1252 to go along with "implementationName". These allow the user code to
1253 specify identification strings to be sent to servers.
1254 Add OID for the new ExtLite attribute set.
1256 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1257 as requested/supplid by Ere Maijala <ere@atp.fi>
1259 For generic frontend server, reverse the order of
1260 "toolkit-supplied / application-supplied" strings sent as implementationId,
1261 Name and Version. Also, remove the spaces around the slash. This brings
1262 the GFS in line with the behaviour of ZOOM-C on the client side.
1264 Add function ZOOM_scanset_display_term.
1266 yaz-client shows scan displayTerm if present.
1268 Utility yaz-iconv is now installed by default along with the man page
1271 Extend configure check for OpenSSL to use pkg-config where available (such
1274 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1275 server to specify uid/gid/mask for socket using the format
1276 unix:[user=uid,][group=gid,][umask=mask,]file=path
1277 If file= is omitted the existing format is assumed, e.g.
1279 in which case the mask is 0666 (rw for everybody).
1281 Major restructure of YAZ source. All source in libyaz is in src directory.
1282 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1283 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1285 Added man page for utility yaz-marcdump (used to be called marcdump).
1286 yaz-marcdump is installed by 'make install'.
1288 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1289 of incoming package failed.
1291 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1293 Change prototype of odr_perror: add const to message string.
1295 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1297 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1298 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1299 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1300 DNS lookup. There should not be any compatibility problems with this
1301 assuming that blocking=1 or 0 is used.
1303 Fix bad reference in UNIX comstack in function cs_addrstr.
1305 Fix for compilation on AIX.
1307 The generic front-end server (server/seshigh.c) now supports returning
1308 Init diagnostics to the client in User-information-field, in
1309 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1312 --- 2.0.4 2003/09/04
1314 Allow any CQL relation (not just all,any,exact,scr).
1316 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1317 that features the same UI.
1319 Implemented command update0 in YAZ client which is equivalent to
1320 update but uses old of Ext Update ASN.1.
1322 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1323 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1324 Previously no OID was used for this info.
1326 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1327 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1328 returns 'malformed search term' otherwise.
1330 SortResponse member resultCount now set to NULL in sort handler of
1333 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1336 Add three new utility functions for translating OIDs between various
1337 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1338 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1339 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1340 char *oid_to_dotstring(const int *oid, char *oidbuf);
1341 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1343 Reverted modifications for ES Update definition for z_IU0Update
1344 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1345 is back to YAZ 2.0.2.
1347 String value attributes for CCL parser.
1349 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1350 which their FirstSearch server returns in Init responses, sometimes
1351 carrying useful diagnostic information when Init fails. This has the
1352 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1353 "z39.50/oclcui.asn", where its definition is somewhat different from
1354 what OCLC document on their web-site, as required to interoperate with
1357 Support for anonymous authentication in yaz-client. Use the command
1360 * Fix the OID of the Index Data-local "admin" Extended Service from
1361 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1362 the 1000, which indicates a locally-defined OID, was a mistake.
1364 --- 2.0.3 2003/06/20
1366 Fix CCL directive @case handling so that it affects string match for
1367 both CCL keywords and qualifiers.
1369 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1370 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1371 Decoder has been updated with ASN.1 changes as listed in
1372 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1373 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1374 z_IUUpdate, remains unchanged.
1376 ZOOM_record_get may now return a record in a specific character set.
1377 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1378 "from" is the character set of record as returned by target. "to" is
1379 the character set to be returned. If omitted, "to" is UTF-8.
1381 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1383 New ODR utility, odr_getelement, which returns name of element for
1384 which encoding/decoding failed.
1386 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1387 in cases where a required element was omitted.
1389 Bug fix: some MARC8 sequences were not converted.
1391 New ZOOM option "step" which specifies number of records to be
1392 retrieved in one chunk. Used in conjunction with "start" and "count".
1394 SRW support for yaz-client. Use scheme http: to use it, e.g.
1397 yaz-client no longer does (un)intelligent character set conversions
1398 by default. Can be enabled with charset and marc_charset commands.
1400 xmalloc trace fix for 64-bit systems such as DEC alpha.
1402 Solaris 2.6 compile fix.
1404 New function, cql_strerror() translates SRW error codes, as returned
1405 by cql_transform_error(), into human-readable English strings. Used
1406 in yaz-client diagnostics when appropriate.
1408 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1409 converts it into a type-1 query which is sent to the server. This
1410 makes CQL available for use with all Z-servers, as opposed to the tiny
1411 minority that can handle CQL queries themselves.
1413 --- 2.0.2 2003/04/28
1415 New Debian package layout similar to the Redhat Package layout.
1417 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1418 and search result respectively.
1420 --- 2.0.1 2003/04/25
1422 Redhat package is now several packages: libyaz (runtime libraries),
1423 libyaz-devel (development and documentation, and yaz (utility programs).
1424 Package spec file by Morten Bogeskov.
1426 New member 'schema' in struct bend_fetch_rr which the name of requested
1427 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1428 handler MAY set this to reflect the schema of the returned record.
1430 New member 'display_term' in struct scan_entry. GFS now sets member entries
1431 and allocates scan entries to be filled by user scan handler. In previous
1432 version, entries member was allocated by the scan handler. That still works,
1433 but the GFS will ignore member display_term - assuming it was NOT set by
1434 the handler. The fact that the GFS now allocates the entries both allows
1435 for new members and makes a scan handler easier to write.
1437 Fix CQL lex buffer overflow.
1439 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1440 SRU default recordPacking is string.
1442 SRU protocol support for frontend server.
1444 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1446 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1448 Added scan for the ZOOM shell (zoomsh).
1452 * String Identifers for Schemas (Amendment 5).
1453 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1454 Old definition for schema
1455 Odr_oid *schema; /* OPT */
1460 Z_InternationalString *uri;
1461 #define Z_Schema_oid 1
1462 #define Z_Schema_uri 2
1465 * resultCount parameter to Sort Response (Amendment 1).
1466 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1468 Support for SRW 1.0 over HTTP. This is an optional feature and
1469 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1472 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1473 on the same port. SRW SearchRetrieveRequests are mapped
1474 to bend_init,bend_search,bend_fetch,bend_close.
1476 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1478 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1479 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1481 ZOOM connections are SRW based if schem http is used for hostname
1482 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1483 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1485 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1486 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1487 distance=n, order=true/false, relation=le, prox unit=word. If
1488 n is omitted, distance 1 is used.
1490 Fixed problem with C compiler include path in wrong order.
1492 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1493 on Solaris. Patch from Ko van der Sloot.
1495 New MARC decode API. All new functions operate on a yaz_marc_t
1496 handle. The most important new functions are: yaz_marc_create,
1497 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1498 decode and destroy respectively. Decoder can produce formats
1499 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1500 include/yaz/marcdisp.h.
1502 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1503 to UTF-8, UCS-32, wchar_t or Latin-1.
1505 * Prototypes for yaz_iconv_-functions moved to separate header
1506 include/yaz/yaz-iconv.h.
1508 Make a few private functions 'static' in unix.c. This prevents
1509 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1511 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1512 are set when Init Response is received.
1514 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1515 but returns diagnostic set as well.
1517 New function yaz_strerror which is a portable wrapper for
1518 strerror/strerror_r/GetLastMessage.
1520 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1521 is returned for MARC. If type is "oai", then OAI MARC is returned.
1523 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1526 --- 1.9.2 2002/11/26
1528 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1530 Fix bad race conditions on SIGTERM and terminate gracefully in
1533 Move retrieval (data1) module to Zebra since nobody seems to be
1536 Add GRS-1 render for ZOOM using same format as yaz-client.
1538 --- 1.9.1 2002/10/05
1540 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1542 Fix broken ESpec handling in data1 module.
1544 SGML reader parses comments and makes them part of the data1 tree.
1546 Added several type casts so that YAZ compiles as C++ code.
1548 ZOOM didn't handle PDU encoding failures properly.
1550 Added more Bib-1 diagnostics (approved extensions).
1552 GNU configure: better check for iconv.
1554 More portable use of accept, getpeername. Check for socklen_t. Use
1555 int/size_t if socklen_t is not defined.
1559 PQF parser rejects bad queries - including those with extra
1560 characters in them. PQF parser used to silently ignore that.
1561 Cleaner API for PQF added, which allows you to get detailed
1562 error information for bad queries (see yaz/pquery.h).
1564 Fixed bug in ZOOM_record_get for type "database".
1566 Implemented mini iconv library supporting conversions between
1567 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1569 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1571 --- 1.8.9 2002/08/20
1573 Fixed ZOOM C record cache so that preferredRecordSyntax and
1574 elementSetName is used to check for already fetched records.
1576 --- 1.8.8 2002/08/02
1578 Added three members in bend_initrequest structure to facilitate
1579 character set negotiation.
1581 Fixed a bug in frontend server that could cause indefinite
1582 loops under rare conditions.
1584 Revised character set utilities (charneg.h) so that encoding
1585 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1587 For PQF, directive @term <type> sets term type for Scan/Search.
1588 Here <type> is general, string, numeric, null. The term type
1589 is inherited - just like @attr.
1591 New call odr_set_charset that sets character set conversion for
1592 international-strings on a ODR stream. Prototype is:
1593 int odr_set_charset(ODR o, const char *to, const char *from);
1594 The InternationalString is still represented as C string in YAZ
1595 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1596 won't). On the protocol level, you can use any encoding.
1598 Support for UNIX sockets in ZOOM.
1600 Solaris recv sometimes returns errno == ENOENT. It is treated as
1601 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1603 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1604 both client and server. Code by Morten Bogeskov.
1606 --- 1.8.7 2002/05/22
1608 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1609 that they can be used directly from Visual Basic. You must recompile
1610 your windows APP if you're using ZOOM.
1612 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1613 Commands "lang" and "charset" sets language and character set respectively.
1614 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1615 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1617 Attributes from multiple CCL fields may be OR'ed rather than merged
1618 using directive "@field or". Fields are still merged by default -
1619 equivalent to "@field merge".
1621 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1624 Fixed bug in zget for parameter ExtendedServicesResponse.
1628 --- 1.8.6 2002/03/25
1630 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1632 Client displays USR.1:SearchResult-1 (hits per term).
1634 Additional Search Info for search in Generic Frontend Server.
1636 Fixed CCL parsing of "field=s".
1638 WIN32 installer - using the excellent NSIS software from nullsoft.
1640 Fixed CCL parsing of "field = - <number>".
1642 Added function yaz_marc_decode that decodes MARC for line mode
1643 display or XML (similar to that used by JZKit).
1645 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1646 Z39.50. But ISO/ILL was, however.
1648 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1649 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1651 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1652 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1654 --- 1.8.5 2002/02/03
1656 New YAZ client features: Command completion and new commands:
1657 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1658 Code provided by Jacob Poulsen.
1660 New call oid_trav, that visits all registered OIDs via callback.
1662 Function ZOOM_record_get now returns const char pointer rather than
1663 void pointer. It saves a lot of type casts.
1665 For YAZ client, command "auth" now allows you to set authentication
1666 in IdPass style. It is enabled when three tokens are given - order
1667 is user, group and password.
1669 Fix memory leaks in MARC record handling for ZOOM.
1671 New option for YAZ client, -k <kilobytes> that sets
1672 maximum record size. Similar to -k option for generic frontend
1673 server and yaz-ztest.
1675 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1677 Prefix query parser reports "fail" when bad attribute set is given.
1679 Fix in MARC decoder. Proximity logging. Fix for attribute set
1680 in scan handler for server. Patches by Shigeru Ishida.
1682 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1685 Configure option --with-openssl=<dir> now works when a directory is
1686 specified. Patch provided by Morten Bogeskov.
1688 New option for YAZ client, -u <auth>, that sets authentication.
1690 ZOOM fix: error information was sometimes "missing", since error
1691 was cleared/reset too when it shouldn't.
1693 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1695 --- 1.8.4 2002/01/04
1697 Scan for ZOOM API. New object ZOOM_scanset. New functions
1698 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1699 ZOOM_scanset_destroy.
1701 New ZOOM function, ZOOM_connection_last_event, that returns type
1702 of last event (such as "receive data", "send data", "apdu received",
1705 New ZOOM option, schema, that specifies schema for retrieval.
1707 New CCL feature. Qualifiers can be aliases for one or more
1708 other qualifiers (if more than one is given, OR is used).
1710 ZOOM uses named result sets if target supports it.
1712 Two new YAZ client commands: . (dot, which sources a script of YAZ
1713 client commands), and ! (to execute shell command.). Implemented
1716 Working on Debian packages.
1718 --- 1.8.3 2001/11/19
1720 YAZ client enables named result sets only if target supports it.
1722 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1724 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1725 with key="host" to get same result.
1727 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1728 Function Z3950_resultset_record(s) returns references to records
1729 "owned" by resultset. To become owner use Z3950_record_clone.
1731 Function z_ext_record handles Extended Services. Thanks to
1734 --- 1.8.2 2001/11/12
1736 CCL Parser fix: ignore token comma when dealing with and-lists.
1738 Documentation updates for COMSTACK.
1740 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1741 Changed prototype Z3950_records. For some functions, int parameters
1742 were changed to size_t.
1744 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1747 New MARC decode/display function, marc_display_exl, which properly rejects
1748 non-ISO2709 records. YAZ client uses it.
1750 --- 1.8.1 2001/10/29
1752 Fix bug: local attribute set wasn't set correctly in PQF strings.
1756 * Old Z39.50 codecs no longer supported.
1758 Added ZOOM C binding. See http://zoom.z3950.org/
1760 Renamed states for COMSTACKs to avoid confusion with events.
1762 Implemented cs_look and proper cs_rcvconnect.
1764 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1766 Configure detects POSIX threads on OpenBSD.
1768 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1769 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1771 When error is returned from present handler, non-surrogate diagnostic
1772 is returned in present response (and fetch handler is no longer called).
1774 * Minor adjustments to pquery parser (PQF). Token characters may be
1775 escaped by using backslash (C-style).
1777 PQF parser allows string attribute values to be specified. For @attr,
1778 non-numeric characters after the equal-sign are treated as strings
1779 (e.g. @attr 9=title).
1781 CCL trunction character may be defined (@truncation in file)
1783 * function zget_ExtendedServicesRequest sets waitAction to
1784 waitIfPossible (was wait).
1786 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1789 CCL operator names may be set in field definition files (CCL_bibset).
1790 See ccl/bib1 for an example.
1792 Fixes in ASN.1 compiler for C++ compatibility.
1794 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1795 and "op_or" to avoid conflict with C++.
1797 Fixed problem with GNU readline detection on Redhat 7.0.
1799 Added step-size for Scan backend handler.
1801 Fixed bug that made the frontend server crash when no attribute
1802 set was specified for scan.
1804 Front-end server automatically switches to original working directory
1805 when installed as an NT service. Previously -w had to be specified to
1808 Added extended attributes for retrieval module (data1), so that data1
1809 records carry d1_readXML/SGML attributes. d1_read also supports
1810 null-data rules ( <tag/>)
1812 On UNIX when POSIX threads are available, a separate library libyazthread
1813 is created. Programmers should link with that library and the yaz library
1814 when using threads. The reason for the split was that some applications
1815 on Linux, such as Apache, doesn't work well when using shared objects that
1818 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1819 (or any frontend server) in SSL mode by specifying ssl: followed by
1820 address. Only tested on UNIX.
1822 Added feature for CCL module. Virtual structure s=al or s=ol generates
1823 and-list and or-list respectively instead of phrase search.
1827 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1828 log_mask_str. This was done to avoid name conflicts with other libraries
1829 (such as other PHP extensions).
1831 Added raw OID member for preferred record syntax (request_format_raw)
1832 and returned record syntax (output_format_raw) for backend fetch method.
1834 Config file yaz-config now accepts options so that it returns specific
1835 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1837 Shared library support for UNIX using GNU libtool.
1839 * Modified backend interface. Request/Response struct's replaced by
1840 one read/write C struct. For example bend_fetchrequest and
1841 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1842 Every handler - even search has to be registered in bend_init
1843 handler. This means that the YAZ library no longer refers to
1844 external functions and it makes it possible to make the whole
1845 thing a single DLL/SO.
1847 Added Segment handler for backend server.
1849 Added Zmbol/Zebra administrative functions to YAZ client.
1851 Threaded frontend server on UNIX (when POSIX Threads are available).
1852 Starting the server with option -T enables multi-threading.
1856 Added configure option --enable-comp/disable-comp to control use
1857 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1858 located in sub directory asn.
1860 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1861 in ${exec_prefix}/bin along with the other programs yaz-client and
1864 GNU automake used to maintain makefiles.
1866 Added several OID's.
1868 Changed retrieval module so that we can load records with no abstract
1869 syntax defined. Tagpaths in these records are fully composed of string
1872 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1876 On UNIX, the generated makefile now supports a proper 'make install'.
1877 The prefix can be set via GNU configure to set the install location
1878 (default is /usr/local).
1880 * YAZ programs client and ztest were renamed to yaz-client and
1881 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1882 locations, such as /usr/bin,/usr/local/bin,etc.
1884 * YAZ Header files were moved from include to include/yaz. YAZ Header
1885 files are referred to as include <yaz/log.h> rather than <log.h>.
1886 The YAZ include path (-I ..) is therefore the same as before. Programmers
1887 should update their #include statements or use -Ipath/include/yaz
1888 instead. The main motivation for doing this change is that YAZ header files
1889 can be installed in "standard" locations /usr/include,/usr/local/include
1890 without introducing conflicts, since ALL YAZ header files are stored
1891 in subdirectory yaz (under /usr/include for example).
1893 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1894 rather than project/workspace files. We switched because project files
1895 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1898 Changed name of logging function, logf, to yaz_log, to prevent name
1899 clash with some math-log functions. The YAZ header log.h defines logf
1900 to yaz_log (#define) so there should be no incompatibilities by this
1903 Added bend_start/bend_stop handlers for server. These handler are
1904 called on start/stop of server. For windows they are called whenever
1905 a service is started/stopped.
1907 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1908 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1909 in util/yc.tcl. The auto-generated C code structures are, in a few
1910 cases, incompatible with the old decoders. There are differences in the
1911 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1912 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1913 The preprocessor variable ASN_COMPILED is defined when the compiled
1914 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1915 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1916 wish to use the old encoders/decoders you can specify --disable-yc
1919 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1920 version so that it supports both new - and old version of DB Update
1922 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1923 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1924 change. The name parameter can be set to 0 in which no name is specified
1925 for the construction. The macros odr_implicit and odr_explicit sets name
1926 parameter to zero for the construction involved. New macros
1927 odr_implicit_tag and odr_explicit_tag are similar to the others,
1928 except that a name parameter is added. For programmers' that don't use
1929 ODR they probably only need to change the call to z_APDU and z_External.
1931 Added access control facility by interfacing the TCP wrapper library.
1932 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1933 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1934 name of the daemon and enables the access control as specified in
1935 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1937 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1938 den Dool <H.M.vdnDool@kub.nl>.
1940 Added reference ID parameter to most functions in server API - refer
1941 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1943 Changed name of ccl library to libccl.a (was ccl.a).
1945 Fixed bug in decoder for Explain (Category TargetInfo).
1947 Added support for GNU readline in client. Thanks to Jacob Poulsen
1948 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1950 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1951 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1952 IMPLEMENTATION! This change was made to the development version before
1953 the ZIG decided to retract the amendment. If any users MUST be
1954 compatible with the original Update definition, PLEASE CONTACT US, and
1955 we will include a separate definition corresponding to the old Update
1956 ES. Note that because of the change to the ASN.1 of the
1957 TaskPackageRecordStructure we cannot define a single structure that
1958 will support both versions.
1960 * Added const modifier to buffer parameter for some ODR/BER encoding
1961 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1962 completeWAIS, odr_dumpBER.
1964 Fixed bug in client.c which caused a crash when a scanResponse didn't
1965 contain positionOfTerm.
1967 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1968 * will cause an error in a client if a non-YAZ target sends both a
1969 * list of Scan entries and non-surrogate diagnostics.
1971 Retrieval module enhancements. Tag sets may be typed in the reference
1972 to it. From the .abs-file the "tagset" directive takes a third optional
1973 integer type for the tag set referenced. From a .tag-file the "include"
1974 directive takes a third optional type as well. The old "type" directive
1975 in the tag set itself is still recognized but acts as the default type
1978 Backend interface change. Individual Scan terms returned from bend_scan
1979 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1980 in include/backend.h.
1982 Retrieval module enhancements. Multiple tag sets and attribute sets may
1983 be specified in abstract syntax specs. Revised the error/warning for
1984 logging messages reported by the retrieval module when reading the
1987 Object Identifier system (oid_..) changed. The API is backwards
1988 compatible but the oid-routines now allocates new OID's when needed.
1989 Raw OID's may be specified in oid_getvalbyname.
1991 YAZ now uses GNU configure to generate Makefile(s).
1993 * Minor changes in some of the member names of DeleteResultSetRequest and
1994 DeleteResultSetResponse. See include/proto.h.
1996 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1997 and added member 'languages' in TargetInfo (which was missing).
1999 Changed the way attribute sets are handled in the retrieval
2000 module. These are now cached, just like the abstract syntaxes
2003 Changed YAZ so that it links with compiled ASN.1.
2005 Added Explain-schema definitions and mapping routines. The following
2006 Explain categories have been implemented: AttributeDetails,
2007 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2009 Fixed minor bug in Windows version of Server Library.
2011 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2013 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2015 Added EXTERNAL: UNIverse Resource Report (non-standard).
2017 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2018 ENUMERATED and SET OF.
2020 * Added 'const' to some of the char pointer arguments for the
2021 functions, data1_read_node, data1_getelementbytagname,
2022 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2025 Fixed bug in data1_insert_taggeddata - the last_child member of
2026 parent wasn't initialised.
2028 * Changed data1_read_record and data1_read_node so that the supplied
2029 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2030 doesn't refer to any parts of the "SGML"-buffer.
2032 Fixed bug in server library (Windows version of statserv_remove).
2034 * Changed code so that it compiles as C++. The type definition
2035 of Odr_fun which is a member of Odr_arm was changed. The result is,
2036 that an explicit typecast is needed for the fun pointer when
2037 using Odr_arm - as in:
2038 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2040 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2042 Implemented the new structured date and time definition as approved
2043 by the ZIG. Added schemaId element to the specificTag in Espec-1
2044 (also approved at the last ZIG). Thanks to RVDM.
2046 Added some Object identifiers (RVDM).
2048 Changed the Update Extended Service (RVDM).
2050 Added command "refid" to client which specifies referenceId for
2051 the following requests.
2053 Implemented extended service handling for server. See ztest.c
2054 for an example as well as backend.h. New handlers are registerd
2055 in the Init handler.
2057 * Changed interface for sort in server.
2059 Added new members to statserv_options_block. It allows a server
2060 to read options from another source than just the command line. Thanks
2061 to Charles Woodfield.
2063 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2064 renamed to zboolean. Some C++ compilers complained about the name.
2066 Minor changes to gils.abs. Added index 's' (sort) on title
2067 and date/time-last-modified.
2069 --- 1.4pl2 1998/1/30
2071 Fixed bug in server library regarding inetd mode (-i). This bug
2072 was introduced by release 1.4.
2074 --- 1.4pl1 1998/1/29
2076 Added sort facility in client and backend server interface.
2078 Fixed problem with dependencies in Makefile(s).
2080 Fixed bugs for encoders/decoders of extended services and
2083 Implemented sub-tree feature for schemas. Sub-trees are
2084 referenced in *.abs-files. See explain.abs for an example
2085 of the use of this feature.
2087 Modified bib1.att; local attributes for ANY didn't include
2088 ANY itself (only affects use of the retrieval module).
2090 Fixed bug in plain SGML reader in function data1_read_node:
2091 tags with prefix "var" was incorrectly interpreted as variants.
2093 Added feature "sub-schemas" to enable references to - and definitions
2094 of - group of elements.
2096 * Removed member parent from type data1_element (in data1.h).
2098 Implemented function odr_nullval() that returns the value of
2101 * Removed member num_children from data1_node (in data1.h).
2103 Made NT service interface part of the server library. The
2104 function statserv_main uses the NT service when required and
2105 calls the statserv_start / statserv_close routines.
2107 Routine zget_SearchRequest and zget_PresentRequest fills
2108 resultSetName/Id member with "default" instead of "Default".
2110 Fixed memory leak in server. Request queue member wasn't freed.
2112 Fixed nmem_exit so that memory is freed.
2116 Revised the CCL parser utility to be thread safe.
2118 Added function, oid_ent_to_oid, to replace the function
2119 oid_getoidbyent, which is not thread safe.
2121 * Added nmem_init and nmem_exit to initialize and release
2122 NMEM resources. Function nmem_init should be called once in the
2123 initial thread before NMEM/ODR is used. statserv.c and client.c
2124 have been changed accordingly. The change was necessary to make
2125 NMEM thread safe. The NMEM memory pool is shared amongst threads
2126 in a process. Unix-based applications will still work fine without
2129 Added NT Services interface for the the Z39.50 (statserv) Server.
2130 Refer to the ztest.c source on the usage.
2132 Windows 95/NT port using MSVC5.0. Project files are included in the
2135 * Defined new 'global' handle for the retrieval (data1) system. The
2136 new handled, data1_handle, describes the state of the data1 system.
2137 This handle is passed as first argument to virtually all
2138 data1 related routines. The functions data1_create and data1_destroy
2139 creates and destroys a data1 handle respectively.
2141 Added ODR encode stream member to all backend request structures
2142 init, search, scan etc. This stream should be used to allocate all
2143 memory used for the response when thread safe operation is needed.
2145 Changed the comstack utility, cs_addstr, to be thread safe. The
2146 returned hostname string returned by the function is now part the
2149 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2150 function. The cs_straddr takes a COMSTACK handle as argument, so this
2151 function must be used after cs_create and before bind/connect.
2152 This function is thread safe.
2154 Moved test server to 'ztest' directory - generic server code still
2155 in 'server' directory.
2157 Made prefix query (pquery.c) utility thread safe.
2159 Added new function modifier YAZ_EXPORT to 'export' public DLL
2160 functions when using windows (see include/yconfig.h).
2162 Added definitions to the OID database (util/oid.c) (RVDM).
2164 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2166 Added call to ccl_rpn_delete in client program.
2168 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2169 release of RPN structure.
2171 Added support for C++, headers uses extern "C" for public definitions.
2172 With input from RVDM.
2174 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2175 Thanks to Ronald van der Meer (RVDM).
2177 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2179 Added support for private extensions to the OID database
2180 (oid_setprivateoids()). Thanks to RVDM.
2182 Added optional, physical ANY (key replication)
2184 Fixed null-reference problem in GRS-1 output filter.
2186 Proximity operator added to Prefix Query Format (PQF).
2188 In test client command "base" accepts multiple databases.
2190 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2194 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2196 Smallish bug-fixes in the new encoders/decoders (explain).
2198 Bug fixed in DeleteRequest.
2200 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2202 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2204 Added SOIF syntax (using private OID for now) to retrieval module and client.
2206 Added Update extended service.
2208 Added SearchResult-1 additional info structure.
2210 Added optional CCL (ISO8777) interpreter as separate module. Available
2213 --- 1.2 1996/6/10 (1st anniversary release)
2215 Added Summary record syntax. Lightly tested.
2217 Added OPAC record syntax. Untested.
2219 Added ResourceReport service encoders/decoders. Untested.
2221 Fixed bug in z_Unit - wrong tagging on unitSystem.
2223 Fixed bug in the DiagRecs decoder.
2225 Added options for max PDU size and session timeout to frontend-server.
2227 Added documentation of query-language parsers and other supporting utilities.
2229 [frontend-server] Added Attribute set to the bend_scanrequest API.
2231 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2232 surrogate diagnostics were generated.
2234 [retrieval] Allow multiple local values for attribute.
2236 [retrieval] Allow multiple attributes per element in .abs files. index type.
2238 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2240 --- 1.1pl2 1996/4/10
2242 Minor changes, mostly specific to Zebra's requirements (retrieval)
2246 Repaired bug in frontend server when running multiple listening
2247 endpoints in dynamic mode.
2249 z_External() now won't break if a known, ASN.1 value comes encapsulated
2250 in an octet-string. The value will pass through unmodified in an Odr_oct.
2252 Added a bit of code to the demo client to decode & display
2253 ASN.1-structured records represented in the octet-aligned branch of
2254 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2256 Added z_ext_getentbyref() to the ASN module. Doc updated.
2258 * Completed the SCAN definition in the ASN module. This may break SCAN
2259 code based on older YAZ-versions at compile-time. The fix is easy -
2262 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2263 under the SCAN definition. Remember to initialize this, server-people.
2265 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2266 that this does not extend to ODR and ASN.
2268 Comstack allows insertion of established socket (primarily for
2269 inetd-operation of servers). Doc updated.
2271 Front-end server can now start from the inetd in TCP mode. Doc
2274 --- 1.0pl4 1996/1/24
2278 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2279 the rank and record number.
2281 Adjustments to the frontend server.
2283 Fixed diagnostic BER dumper. It ignored the file argument.
2287 Various changes to retrieval module.
2289 Changed the union discriminators of the protocol files from enums to
2290 ints paired with #defines.
2292 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2295 *Changed operator in the RPN structure to 'roperator', again to avoid a
2298 Fixed problems in Explain decoders/encoders.
2300 --- 1.0pl2 1995/12/6
2302 Memory bug in log module fixed.
2304 --- 1.0pl1 1995/12/5
2306 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2308 Bug in Explain DatabaseInfo module fixed.
2310 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2314 The shift to v1.0 signals that we now consider the *core* functionality
2315 of YAZ reasonably stable (the core being more or less equivalent to
2316 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2317 tested (Explain not at all - though that will happen soonish).
2319 Minor changes to code to support Windows port.
2321 Various minor changes after we're getting to use GRS-1 & co. more.
2323 Added Espec-1 format.
2325 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2326 of the protocol and it cannot be selected when encoding (maps into 'string'
2327 when decoding). Needed to talk to some servers.
2329 Demo client can request simple element set names.
2331 Added Diagnostic Format encoders/decoders.
2333 Added simple Close handling to frontend server (no hooks for resource
2334 reporting yet), and demonstration client.
2336 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2338 --- 1.0b3 1995/08/24
2340 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2341 handled incorrectly when records were requested in the searchResponse. This
2342 will only affect you if you use the frontend-server.
2344 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2345 Test-client will ask for and print GRS1. Ztest will return dummy records
2348 Added Explain encoders/decoders to the service-level API. Untested.
2350 Added Extended Services: Item Order encoders and decoders to the Service-
2351 level API. Untested. We could use a recent copy of the pertinent bits
2352 of the ILL protocol to add those bits.
2354 Added diagnostic format 1 encoders/decoders to the service-level API.
2357 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2358 odr_cons.c, which causes a more correct output.
2360 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2361 was always set to 0 when no records were requested in the searchRequest.
2363 * Added better external-handling. This shouldn't harm old code that
2364 *encodes* externals. It can break code that looks for a
2365 'single-ASN1-type' representation, since those types that are known
2366 are now decoded immediately. Look at the SUTRS sample code in
2367 seshigh.c and client.c. Documentation updated.
2369 Handling of structured records in bend_fetchresponse. Length -1 marks
2370 structured record, type is deduced from format field.
2372 --- 1.0b2 1995/06/27
2373 Fairly quick maintenance release to add SUTRS support.
2375 Fixed handling of SUTRS records in the demonstration client.
2377 * Added format field to the bend_fetchrequest and bend_fetchresponce
2378 structures of the backend API (frontend server). When the record is
2379 returned, the value of the format field is mapped to an OID. The
2380 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2381 of the record. The special value VAL_NONE in the bend_request means
2382 that no specific format was requested by the client. Documentation
2383 updated accordingly. Test server (ztest) will return a fixed dummy
2384 SUTRS record if your client requests SUTRS.
2386 Documentation updated accordingly.
2388 You can now set external libraries and RANLIB support in the top-level
2392 First public release.
