1 Added support for the use of the older versions or Extended Service
2 Update in ZOOM. To faciliate this, an option "updateVersion" may be
3 set to the version , 1=first, 2=second, 3=third. The third version is
4 what ZOOM C has used so far. And that, obviously, is the default.
6 Added support for CCL queries in Z39.50 queries sent to the GFS (and
7 therefore in Zebra and in SimpleServer-based applications). The new
8 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
9 qualifier file used to transform incoming CCL queries into Type-1 RPN,
10 which is passed into the back-end search callback function.
14 Fixed bug #1208: SSL appears to be broken in ZOOM.
16 Fixed bug #1206: Libxml2 include path weirdness.
18 Added oid_name_to_dotstring.
20 Allow elementSetName to be specified for ZOOM C record update.
22 Allow waitAction to be specified for ZOOM C based for Extended Services.
24 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
25 syntax OID. Bug introduced in YAZ 3 series.
27 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
31 Fixed bug #1157: yaz-client does not read .yazclientrc from current
32 directory. yaz-client now reads commands from file given by option -f
33 if specified; then tries to read .yazclientrc in current directory.
34 Failing that, it reads .yazclientrc from user's home directory.
36 Added support for correlationInfo Note and ID for Record Update via
39 Added yaz-client command querycharset which specifies character set for
40 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
41 (termListAndStartPoint).
43 Charset ISO5428:1984 is an alias for ISO5428-1984.
45 Implemented a way to perform scan in a result set using Z39.50. This
46 is achieved by attaching the result set name in the characterInfo
47 (type InternationalString) of OtherInformation in the Scan Request PDU.
48 The result set is identified in the otherinformation by the new OID:
49 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
50 This allows for scan in result set and faceted search . Zebra did some
51 of this in the APT term using attribute type 8 and value being result
52 set. Using the OtherInformation approach for this is cleaner and easier
53 to work with in proxies and the like. This facility can be used in
54 yaz-client using new command setscan which takes a result set as first
55 argument, start position (APT) as second.
57 Changed decoding of SRU XML packed records to deal with servers that
58 have recordData with XML data with multiple root nodes. Also make
59 comparison for recordPacking case insensitive. Again, one server
60 returns "XML" where others return "xml".
62 For SRU responses allow Content-Type application/xml as well as text/xml.
66 Fixed bug in character set conversion of BER strings. Bug introduced
71 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
73 For OID class, use oid_class consistently.
75 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
78 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
79 character set for bibliographic information interchange". By Giannis Kosmas.
81 Added documentation on new OID API.
85 Changes to generic frontend server interface: added new member
86 'query_charset' for bend_initrequest structure. A backend init handler
87 should set this member to its native character set for query terms.
88 When defined, the frontend server logic will announce this character set
89 to a client if the negotiationModel bit is set by the client. All server
90 implementors are encouraged to specify this. If a backend server does not
91 specify this a warning is issued using yaz_log(YLOG_WARN,..).
93 Added CCL utility to remove terms (stop words) from resulting RPN
94 tree. This is handled by functions with prefix ccl_stop_words_ .
96 New ZOOM C option, "rpnCharset", which allows client-side conversion of
99 Clean-up the CCL API. Moved some internal structures from ccl.h to
100 private header cclp.h. Changed ccl_parser_create so that a Bibset must
101 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
102 This is replaced by ccl_parser_find_str which takes a string instead.
104 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
105 libyaz.la is the core of YAZ except the generic frontend server and
106 does not depend on POSIX threads anymore. libyaz_server.la is the
107 generic frontend server facilities and uses POSIX thread functionality
108 if available. The libyaz.la no longer depends on POSIX threads because
109 the number of global structures is limited. NMEM no longer re-uses blocks
110 between threads ; it simply free's memory immediately but allocates in
111 "large" chunks as usual. We don't expect any performance penalties
112 because of this. The yaz_log system is still using a global log_level so
113 caution must be taken when modifying it with yaz_log_init_.. +
114 yaz_log_mask_str. This, however, should not cause any trouble because
115 these functions are called during initialization of application code
116 anyway. `yaz-config --libs server` returns libs for server applications;
117 `yaz-config --libs` returns libs for non-server applications.
119 New OID database - with public definitions in oid_db.h. Removed old OID
120 database including the head oid.h and definitions such as enum oid_value
121 and struct oident. The new OID database uses the same string names as
122 before but the 'protocol' is gone. There are now only two representations
123 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
124 converts from string to OID; functions with prefix yaz_oid_to_string
125 converts the other way.
127 Change to emit_term() in CQL-to-PQF query translation: when a term has
128 the /regexp relation modifier, do not process it for leading and
129 trailing "^" and "*", which have quite different meanings in regular
132 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
133 write handlers no longer carries a 'last' parameter. This will make
134 yaz_iconv flush "less" characters. A flush is performed by call to
135 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
137 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
138 removed, because function yaz_query_to_wrbuf does the same.
140 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
141 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
143 Deprecated MARC utility functions removed.
145 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
148 Branch split: YAZ_2_1_55_branch
150 --- 2.1.54 2007/03/16
152 Fix to ZOOM-C so that transparent reconnection is properly handled on
153 connections that are in asynchronous mode.
155 Fixed compilation on OpenBSD 4.0.
157 Large strings in GRS-1 records are now properly displayed in yaz-client.
159 Added character conversion support for "advancegreek"; based on patch from
162 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
163 sequence is met. Before the error was not set so it would be unknown.
165 Adjust yaz-marcdump MARC reader so that it skips until record separator
168 --- 2.1.52 2007/03/07
170 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
171 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
172 fd_set structure used as a bitmask for the FDs to be selected on.
174 Using ACX_PTHREAD macro to check for POSIX threads.
176 Fixed have-vsnprintf check.
178 --- 2.1.50 2007/02/23
180 Fixes for configure on BSD. Bug #900.
182 Added snprintf/vsnprintf wrappers for systems that don't have
183 limits (heavens forbid).
185 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
186 created before all previous tasks were completed and removed from the
187 task queue, the new task could be removed by a mistake.
189 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
191 Implemented pass-through CQL-to-PQF conversions. Bug #861.
193 Fixed bug #832: Problem with MARC/charset in yaz-client.
195 Fixed bug #668: save command line history for yaz-client.
197 Fixed bug #830: pkg-config support.
199 --- 2.1.48 2007/01/23
201 Extended ZOOM result set options with two options that may be read by
202 a client: resultSetStatus and presentStatus with values as specified for
204 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
206 Fixed bug #827: Using SSL fails on Debian etch.
208 Fixed bug #826: Weird looking chars for set of MARC records.
210 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
211 that is treated as an ItemOrder with itemRequest being an XML document
212 external. The value of "doc" is the content.
214 Extended the GFS search facility. New member of bend_search_rr
215 'estimated_hit_count' signals that hits is known to be an estmate
216 (higher or lower than real hit count). New member 'partial_resultset'
217 signals that the search was partial (hit count is lower or equal than
218 real hit count). For Z39.50, the information is stored in resultSetStatus
219 member of SearchResponse APDU. For SRU, the information is signalled
220 via SRU diagnostic 59: "Result set created with valid partial results
223 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
225 --- 2.1.46 2007/01/13
227 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
229 Added ZOOM_connection_peek_event.
231 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
232 the following new functions:
233 ZOOM_event_nonblock, ZOOM_connection_process,
234 ZOOM_connection_get_{socket,mask,timeout},
235 ZOOM_connection_fire_event_{timeout,socket}.
236 The existing blocking event handler, ZOOM_event, is a wrapper for the
237 + blocking ZOOM_event_sys_{poll,select}.
239 Implemented function ccl_xml_config which parses XML version of CCL
240 configuration (bug #798).
242 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
244 Added timings utility (yaz/timing.h)
246 --- 2.1.44 2007/01/03
248 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
251 Fixed bug #779: Rotation of apdu.log fails.
253 Fixed for character set conversions:
254 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
255 Honor G1 set in MARC-8 decoding.
257 --- 2.1.42 2006/12/17
259 Fixed bug #775: char conversion does not handle Alternative UTF-8
262 Implemented function yaz_marc_read_line which parses MARC line format
263 records. There is a wealth of formats out there. So far, this function
264 reads line records produced by yaz_marc_write_line.
266 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
267 more generic and easier to remember(!) options: -i format and -o format
268 which specifies input format and output format respectively - where
269 format is one of "marc", "marcxml", "line", "marcxchange".
271 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
272 does not print anything except warnings for records.
274 For yaz-marcdump, added support for MARC split into files (-s) with a given
277 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
278 spec, at http://www.loc.gov/standards/sru/record-update/
279 This has changed the binary layout of the following structs:
280 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
281 bend_update_rr . Patch by Ko van der Sloot.
283 Added GFS utility function bend_assoc_is_alive which returns 1 if
284 association is still alive (client is connected); 0 otherwise (client
285 closed connection). This allows busy servers to stop working for
288 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
289 been a separate piece of software. This version of ziffy has been modified
290 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
292 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
294 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
295 Client code may now interrogate options such as "init_opt_sort" to
296 find out whether the server claims to support various options.
298 --- 2.1.40 2006/11/27
300 Added utilities yaz_{set,get}_esn to set/get element set name from
303 Removed the build of libyazthread.la. The libyaz.so is the threaded version
304 of YAZ and has been so since YAZ 2.1.10.
306 Implemented ZOOM_record_error which returns error information for
307 record (surrogate diagnostic).
309 --- 2.1.38 2006/10/31
311 Updates for SRU Update by Ko van der Sloot:
312 1. Changed name from "operation" to "action"
313 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
314 versions in the code, marked as 'backward compatible'.
315 3. Added diagnostics for SRU Update.
317 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
319 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
321 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
323 For GFS, fixed problem with SRU diagnostic 'First record position out of
324 range' being issued for 0 hits.
326 zoomtst10 part of Windows Build.
328 --- 2.1.36 2006/10/13
330 Implemented yaz_filepath_comp which splits a path into file path
331 components (required by Zebra 2.0.3+).
333 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
334 BSD inspired license until now so this should not have any real impact on
335 anybody. See http://www.opensource.org/licenses/bsd-license.php
337 Fixed bug #687: Missing log lines.
339 Fixed bug #678: CQL to PQF translation does not preserve double-quote
342 Fixed bug #689: SRU diagnostics to be added.
344 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
345 whether a connection is idle (no more work do do).
347 --- 2.1.34 2006/10/04
349 Change type of optval from long to int for invocation of setsockopt with
350 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
352 Added support for specifying the max log file size for the Generic
353 Frontend Server. The size is given with option -r.
355 --- 2.1.32 2006/09/21
357 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
359 --- 2.1.30 2006/09/17
361 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
364 Fixed bug in Generic Frontend Server that could cause a server to stop
365 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
367 For the generic frontend server, the maximum record size is used as maximum
368 size of incoming packages (SRU + Z39.50). The value until was previously
369 only used in Z39.50 Init negotiation and, later, in a session controlled
370 sizes of records returned. This is controlled using -k option. It can be
371 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
373 --- 2.1.28 2006/09/04
375 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
378 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
380 New option for yaz-marcdump -lpos=value which allows setting a portion
381 of MARC header to a certain value.
383 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
385 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
386 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
388 --- 2.1.26 2006/08/15
390 Fixed problem with SRU mode type (soap, get, post) for yaz-client
393 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
395 --- 2.1.24 2006/08/08
397 Fixed MARC ISO2709 encoding routines to deal with character set
400 Minor changes to GFS logging. Database included in search request log
403 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
404 cached/multiple records.
406 Shared libraries are built by default on Unix+configure.
408 Changed cql2pqf transformation to use a different evaluation order. The
409 new order is: always, relation, structure, position, truncation, index
410 and relationModifier. Old order was: always, relation, relationModifier,
411 structure, index, position, truncation. Note that the the latter ones
412 override former ones for identical attributes.. The new scheme means that
413 it is possible to override any existing attribute with a relationModifier.
414 And also that it is possible to override everything for the index rule
415 (except the ones listed in relationModifier). No order is perfect but this
416 one, we believe, covers more real cases.. The "always" should have been
417 called "default", since the attributes there can be overridden with all
420 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
421 compilation phase, but also for yaz-config --cflags output. This allows
422 us to have public headers with Libxml2 stuff in them . It should also,
423 eventually, make Libxml2 checks redundant in packages using YAZ, such
426 --- 2.1.22 2006/06/15
428 Changed SRU update structure bend_update_rr so that SRU diagnostics are
429 stored in uri, message and details.. Previously diagnostics were stored
430 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
431 compatibility.. but he's probably the only one affected, so.
433 Added support for CCL, compiled on the client side, in ZOOM-C. This
434 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
435 input; the resulting query objects can be used for for searching with
436 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
438 YAZ' configure searches for OpenSSL by default.
440 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
441 SL_CTX_use_certificate_file. See
442 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
443 for more info. Thanks to Ko van der Sloot.
445 --- 2.1.20 2006/06/02
447 Bug #600: SRU GET, POST support for yaz-client. Introduced
448 command 'sru' which selects method SOAP/GET/POST.
450 Allow missingValueAction to be specified for the sortspec string -
451 function yaz_sort_spec. By default, the missing value action is null.
452 Use ! to specify "abort". Use = followed by stringvalue to specify default
455 Ensured that Present-handler (if defined) is called in GFS before any call to
456 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
457 searchRetrieve requests.
459 Documentation for YAZ is now based on the Docbook XML/XSLT using
460 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
461 is no longer depending on jade/openjade or docbook-to-man scripts.
462 PDF is no longer part of the distribution - but can optionally be
463 made using DSSSL/jadetex or FOP.
465 Added retrieval handling support in Generic Frontend Server to support
466 conversion between MARC/XML as well as XSLTtransforms. See
467 etc/yazgfs.xml for an example.
469 Added Authentication support to Generic Frontend Server in SRU
470 mode. Authentication using HTTP Basic is supported, as is the use
471 of 'x-username' and 'x-password' parameters in the request itself.
473 Added support for a new character set MARC8s identical to MARC8 except
474 that it converts combined characters to single Unicode characters in the
475 Latin-1 range (when possible).
477 --- 2.1.18 2006/04/24
479 ASN.1 compiler 0.4: generates brief Doxygen file header for
480 generated .h/.c files.
482 Utility yaz_iconv now supports conversion to MARC-8.
484 New facilities for the MARC module. The reading - and writing of
485 content are separate methods for the yaz_marc_t handle. The following
486 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
487 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
488 format). Write functions have prefix yaz_marc_write_.. The existing
489 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
490 available. Removed support for OAI-MARC and simplexml (not the
491 simplexml from PHP5).
493 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
494 to be returned for this connection.
496 --- 2.1.16 2006/03/31
498 Allow multiple languages and charsets to be specified with
499 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
500 negcharset iso-8859-1,utf-8
502 Translation of proximity nodes from CQL into PQF now works.
504 Moved to automake 1.8, 1.9.
506 Added function yaz_log_set_handler which allows a log handler to be
507 installed. This handler will be called for all log messages. Output
508 to file is also produced; but that can be disabled by passing NULL
509 fname to yaz_log_init_file.
511 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
513 For SRW (including GFS), accept application/soap+xml as content-type
516 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
517 produces NO stylesheet reference even if a default stylesheet is specified
520 --- 2.1.14 2006/03/14
522 Updated Windows package to include yazd.dll + yazd.lib for the
523 Development component.
525 If the environment variable YAZ_LOG is set, then it is used as a
526 string indicating the default level of logging to use if not
527 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
528 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
529 used as before. So, for example, to omit warnings from YAZ logging,
532 cql_transform() now map structure and other attributes before indexes,
533 so that index-specific structures and other attributes can override
534 defaults. So now a combination of mapping specifications such as:
536 index.dc.date = 1=date-modified 4=5
537 does the right thing.
539 cql_transform() now also respects the "always" mapping specification,
540 which establishes an initial set of attributes to be used for all
541 terms except where overridden by more specific attributes associated
542 with the index, relation or modifier.
544 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
545 which mode to use; one of "post", "get" or "soap" (SRW, default).
547 Fixes for yaz_iconv routines: changed trie-based character set conversions
548 to use only non-negative values for bit fields due to Sun's C compiler not
549 supporting negative values.
551 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
552 sequences where not read correctly. Fix by Rustam Usmanov.
554 Updated win/makefile to use options, settings which makes things
555 compile with VS C 2005.
557 --- 2.1.12 2006/02/01
559 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
561 In ZOOM socket code, use select instead of poll on MacOSX.
563 ZOOM-C now support client-side compilation of CQL into RPN that is
564 sent to the server, enabling CQL to be used against all Z39.50
565 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
566 ZOOM_query object, and submit it using ZOOM_connection_search().
567 The CQL-to-RPN translation uses a configuration file, the name of
568 which must be specified in the Connection's "cqlfile" option.
570 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
571 function, which takes as its start-term parameter a ZOOM_query object
572 (which may have had either CQL or RPN set into it).
575 --- 2.1.10 2005/11/29
577 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
578 GFS to support this as well. Backend handler, bend_srw_update, does the
579 update work. Code contributed by Ko van der Sloot.
581 Allow retrieval of Search Result-1 information in ZOOM by the use of
582 options that are attached to a result set. ZOOM documentation updated
585 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
586 UTF-8 conversion. Patch by Raj Patel.
588 Added option -m to GFS to control formatting of timestamps in log file.
590 Added 'exit' as synonym for 'quit' in yaz-client
592 Added support for specifying SRW resultSetId + resultSetIdleTime in a
593 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
594 for the new members. Patch by Ko van der Sloot.
596 Added support for SRU POST. It is supported for content-type
597 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
599 Do not build the separate Multi-threaded (MT) library libyazthread.la.
600 Instead make the library libyaz.la multi-threaded. Threading as a whole
601 can still be disabled by configure option --disable-threads. Previosly,
602 with older GLIBCs there were problems with MT libs under Apache. This
603 has now been fixed a long time ago.
605 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
608 CQL module modified to be case insensitive for relations/indexes/operations.
610 Fixed bug in CQL transform code: incorrect value relationModifieder
613 Added 'show all' command for yaz-client which retrieves all results
616 Added new yaz-client, xmles, which takes a (private) OID and
617 a document to be sent as an extended service request.
619 Describe new yaz-client commands wait_response and set_auto_wait.
621 Increase TCP/IP listener backlog from 3 (which I am guessing was
622 copied from the SunOS manual entry way back when) so SOMAXCONN, so
623 that the socket will queue as many incoming connections as it's able
624 to handle ongoing connections. In other words, it will never now
625 refuse a connection that it would be able to handle merely because
626 it's not got around to accepting() enough of the pending connections
627 yet. This is the behaviour anyway under Linux, where the listen()
628 argument is ignored; but not under BSD and on systems such as
629 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
630 YAZ-based servers should now be uniform across operating systems in
633 yaz-marcdump uses 64-bit file access on some systems. This is enabled
634 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
635 This allows yaz-marcdump to read large MARC batches (>2 GB).
637 Modified all YAZ source files - except the source which is auto-generated
638 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
641 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
642 corresponding to the existing *_setl() function. These allow option
643 values containing arbitrary valuues.
645 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
646 ZOOM_resultset_sort() in new applications. Its behaviour is identical
647 except that it returns an indicator of whether or not the sort
648 criterion was accepted (0 for OK, -1 for invalid).
652 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
653 MARC output rather than returning "new" buffer.
655 yaz-client warns about unknown init options.
657 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
661 Added support for SRW sort in Generic Frontend Server. Patch
662 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
663 sortKeys - or NULL if none is provided.
665 Fixed bug #307: It was impossible to specify indefinite/no timeout
666 for ZOOM_event. Special timeout value -1 now means indefinite timeout
669 Added support for multiple languages and charsets to be specified in
670 ZOOM. Each charset/language is separated by a blank. If negotiation is
671 in effect in init-response, Option
672 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
673 Code based on patch by Vasiliy Osadchuk.
675 Fixed bug #306: infinite recursion that occurred when calling
676 yaz_log_level_init as the first call (before other log level or
679 Fixed bug in scan handling in front end server: if preferred-Position-In-
680 Response was non-present, a NULL pointer referece was performed.
684 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
685 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
686 now defined for all those error codes. So instead of putting 109 in
687 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
688 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
690 Modified the yaz-marcdump utility to skip garbage bytes between MARC
693 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
695 Program yaz-client now exits and produces an error message if multiple
696 Z39.50 servers are specified on the command line (none or one allowed
699 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
704 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
706 Fixed bug #272: Preserve spacing for CCL terms.
710 Added support for virtual hosts and multiple backend servers for
711 the YAZ frontend server. The configution is XML based and
712 support specificition of CQL to RPN mappings and explain information.
713 See section "Virtual Hosts" in the YAZ manual.
715 Extended OPAC display utility. OPAC display utility renders
716 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
717 to supplement yaz_marc_decode_wrbuf.
719 Fixed a bug in MARC decoder that could caused it to crash for some
720 invalid MARC records. More diagnostics and warnings where added in
721 XML output (warnings, etc are stored in comments).
723 --- 2.0.34 2005/02/08
725 Fixes for UNIX domain sockets. Bug #261.
727 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
729 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
730 Added yaz_marc_subfield_str which defines subfield lead string which is
731 used in YAZ_MARC_LINE format. Default string is blank+$. Added
732 yaz_marc_endline_str which defines end of fields string used in
733 YAZ_MARC_LINE format. Default string is newline.
735 Experimental support for MarcXChange. This format can be produced
736 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
737 http://www.bs.dk/standards/MarcXchange.xsd
739 Added yaz-client commands scansize that sets maximum number of
740 entries to be returned by scan.
742 --- 2.0.32 2005/01/11
744 Added support for SRW scan in yaz-client and Generic Frontend Server.
746 * Added whereInList member to SRW Scan Term.
748 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
750 Fixed NMEM system to return aligned blocks on the smallest boundaries
751 that are suitably aligned for all possible types on the particular
752 architecture YAZ is being built for.
754 --- 2.0.30 2005/01/04
756 Fixed numerious warnings that was issued with newer versions of GCC.
758 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
759 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
762 Make YAZ Generic Frontend Server slightly faster.
764 Enhance (and reduce) logging for Generic Frontend Server.
766 Revert YAZ log system so that it flushes every write operation
767 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
769 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
770 instead of LOG_, due to name clash with syslog(3). LOG_ are still
771 present. New applications should define YAZ_USE_NEW_LOG=1 - this
772 will effectively disable old definitions.
774 --- 2.0.28 2004/11/09
776 Added yaz_log_time_format which specifies log format using
779 Added yaz_log_module_level which returns mask for a module. Value
780 is non-zero mask a if module is enabled; zero if disabled.
782 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
783 in include/yaz/cql.h.
785 Fixed bug #176: Dont throw diagnostics on empty SRU args.
787 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
789 Fixed bug #172: RPM builds does not enable SSL.
791 Doxyfile.in part of dist. Doxyfile generated by configure.
793 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
794 are given and the corresponding component does not exist.
796 Extend CCL documentation in YAZ reference. Describe r=r.
798 --- 2.0.26 2004/10/01
800 Fixed MARC->MARCXML conversion to properly deal with
801 fields, subfields, indicators having non-ASCII characters.
803 Fixed MARC->MARCXML conversion so that ASCII control characters
804 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
807 Added YAZ GFS support for conversion from Z39.50 surrogate
808 diagnostics to SRW surrogate diagnostics.
810 Bug fix: YAZ GFS did not return schema in explainResponse.
812 --- 2.0.25 2004/09/30
814 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
815 now converts recordSchema to elementSetName as well as schema URI.
817 Fixed bug in COMSTACK that prevented HTTP request packages from being
820 --- 2.0.24 2004/09/29
822 Added CCL facility r=r "range" which is similar to r=o "ordered" but
823 does not require white-space before and after the dash in a range, e.g.
824 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
827 Fixed a few AC_TRY_LINK configure tests that did not operate properly
828 due to new GCC removing "redundant" code.
830 Added yaz-client commands scanpos and scanstep that sets preferred
831 position and step-size for scan.
833 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
835 Added CCL utility ccl_qual_buf which parses one or more CCL
836 spec lines in a buffer.
838 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
839 of name and value - ignoring empty lines and comments.
841 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
843 Added odr_get_element_path which returns current element path for an
844 ODR handle. This utility is useful in error handling or user-defined
847 Added ODR_PRINT utility odr_set_stream which is is a more generic
848 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
849 to a write function and pointer to close function. The close function - if
850 non-NULL - will be called during odr_destroy.
852 Fixed bug in CCL parser where truncation char was not removed from
853 right side when truncation=both was in effect.
855 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
858 --- 2.0.23 2004/08/11
860 Fix buffer overrun in CQL parser when dealing with proximity (%).
862 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
863 to UTF-8/UCS conversion is now only based on codetables.xml.
865 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
867 --- 2.0.22 2004/08/06
869 Add support for more "commit changes" in ZOOM (uses Extended Services).
871 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
874 Yet another small fix for configure of SSL.
876 --- 2.0.21 2004/05/14
878 Fix SSL libs for configure when --with-openssl=DIR is given.
880 --- 2.0.20 2004/05/10
882 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
884 SSL comstack now uses yaz.pem certificate file on server side
885 by default. Certificate filename can be configured by calling
886 comstack function cs_set_ssl_certificate_file before cs_bind is used.
888 Fix bug regarding multiple calls to ZOOM_connection_connect.
890 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
892 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
893 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
895 ZOOM now allows inspection of X509 peer certificate for verification.
896 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
898 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
899 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
900 as "modular" but it simplifies things.
902 Added cs_get_peer_certificate to that returns peer X509 PEM.
904 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
905 NULL if SSL is unavailable.
907 Documentation about MARC decoding tools.
909 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
911 --- 2.0.19 2004/03/30
913 Rename CHANGELOG to NEWS to follow GNU style packing.
915 Fix bug with missing initialization of member in init_diagnostics.
916 This bug affects threaded version of GFS server.
918 --- 2.0.18 2004/03/20
920 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
923 Ensure zlib.dll is packed with Windows install.
925 --- 2.0.17 2004/03/17
927 Fix encoding of xsd:string to use text instead of CDATA.
929 Fix endless loop in CQL parser with unbalanced ".
931 Use a more compact way to store MARC-8 conversion tables.
933 --- 2.0.16 2004/03/16 Debian only
935 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
938 Update CQL parser to use new CQL 1.1 modifiers for booleans and
943 --- 2.0.15 2004/03/01
945 Another fix for decoding of XML packed records.
947 --- 2.0.14 2004/02/25
949 Fixes for Chunked encoding. White space not ignored after length spec.
951 Update NS and use default NS for SRW diagnostic elements.
953 --- 2.0.13 2004/02/23
955 Implement ZOOM_resultset_cache_reset which resets record cache.
957 Implement ZOOM_resultset_sort which sorts a result set.
959 Implement chunked HTTP transfer.
961 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
963 --- 2.0.12 2004/02/16
965 Added member 'schema' to bend_explain_rr structure so that backend
966 can specify explain record identifier. Defaults to Zeerex 2.0.
968 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
970 --- 2.0.11 2004/02/16
972 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
975 Added init command for yaz-client which sends "extra" init request.
977 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
978 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
980 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
982 Make ZOOM error code for "invalid query".
984 Fixed compilation for SSL which wasn't properly enabled for all platforms.
986 --- 2.0.10 2004/02/05
988 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
991 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
993 Added option -p <file> to make Generic Frontend Server to write PID file.
995 Added option -D to put Generic Frontend Server in background on its own.
997 Make ZOOM C recognize option "password". If unset, "pass" is used
998 (for backwards compatibility).
1000 Fixed a bug in Generic Frontend Server that could make it crash if a
1001 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1004 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1005 Must be issued before open, in order to be in effect.
1007 --- 2.0.9-6 2004/01/12 Debian/Windows
1009 Make the SRU server more picky WRT unknown params, etc.
1011 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1013 New YAZ client command, options, that sets Z39.50 options.
1015 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1016 options from a string of tokens (one token for each option bit).
1018 Update SRW diagnostic code messages.
1020 --- 2.0.9-5 2004/01/07 Debian/Windows
1022 Handle user defined stylesheet for SRW/SRU.
1024 --- 2.0.9-4 2004/01/06 Debian/Windows
1026 Fix bug in decoding of Content-Length.
1028 --- 2.0.9-3 2004/01/06 Debian/Windows
1030 Fix a bug with decoding of XML packed records.
1032 --- 2.0.9-2 2004/01/05 Debian only
1034 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1036 Fix bug in SRW/SRU diagnostics decoding.
1038 --- 2.0.9 2004/01/05
1040 Fixed bug in Generic Frontend Server which could drop records exceeding
1041 preferred message size. Reported and fixed by Irina Dijour.
1043 Fixed calculation of package size for structured records in Generic
1044 Frontend Server. Reported and fixed by Irina Dijour.
1046 Fixed namespace for SRW/SRU diagnostics.
1048 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1050 --- 2.0.8 2003/12/22
1052 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1053 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1056 CQL changes to reflect recent changes to the specification:
1057 * Documentation talks about context sets instead of index sets.
1058 * Documentation talks about indexes instead of qualifiers.
1059 * The CQL-to-PQF transformer's configuration file now uses
1060 "index.set.name = <attributes>" instead of the old form
1061 "qualifier.set.name = <attributes>". (Both forms are still
1062 understood but the latter is deprecated.)
1063 * CQL terms with no explicit index specified are now interpreted as
1064 cql.serverChoice instead of srw.serverChoice (which of course
1065 behaves exactly the same.)
1067 --- 2.0.7 2003/12/16
1069 MARC conversion can now generate ISO2709 output in another
1070 character set. yaz-marcdump uses this facility if you invoke it
1073 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1074 functions from there can be used from C++.
1076 --- 2.0.6 2003/12/04
1078 Frontend server now transfers memory from decoded packages to stream
1081 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1082 references to show up.
1084 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1085 the ZOOM Abstract API. The older names for the same options are still
1086 also supported for the benefit of old applications.
1088 ZOOM-C supports "implementationId" and "implementationVersion" options
1089 to go along with "implementationName". These allow the user code to
1090 specify identification strings to be sent to servers.
1091 Add OID for the new ExtLite attribute set.
1093 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1094 as requested/supplid by Ere Maijala <ere@atp.fi>
1096 For generic frontend server, reverse the order of
1097 "toolkit-supplied / application-supplied" strings sent as implementationId,
1098 Name and Version. Also, remove the spaces around the slash. This brings
1099 the GFS in line with the behaviour of ZOOM-C on the client side.
1101 Add function ZOOM_scanset_display_term.
1103 yaz-client shows scan displayTerm if present.
1105 Utility yaz-iconv is now installed by default along with the man page
1108 Extend configure check for OpenSSL to use pkg-config where available (such
1111 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1112 server to specify uid/gid/mask for socket using the format
1113 unix:[user=uid,][group=gid,][umask=mask,]file=path
1114 If file= is omitted the existing format is assumed, e.g.
1116 in which case the mask is 0666 (rw for everybody).
1118 Major restructure of YAZ source. All source in libyaz is in src directory.
1119 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1120 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1122 Added man page for utility yaz-marcdump (used to be called marcdump).
1123 yaz-marcdump is installed by 'make install'.
1125 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1126 of incoming package failed.
1128 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1130 Change prototype of odr_perror: add const to message string.
1132 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1134 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1135 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1136 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1137 DNS lookup. There should not be any compatibility problems with this
1138 assuming that blocking=1 or 0 is used.
1140 Fix bad reference in UNIX comstack in function cs_addrstr.
1142 Fix for compilation on AIX.
1144 The generic front-end server (server/seshigh.c) now supports returning
1145 Init diagnostics to the client in User-information-field, in
1146 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1149 --- 2.0.4 2003/09/04
1151 Allow any CQL relation (not just all,any,exact,scr).
1153 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1154 that features the same UI.
1156 Implemented command update0 in YAZ client which is equivalent to
1157 update but uses old of Ext Update ASN.1.
1159 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1160 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1161 Previously no OID was used for this info.
1163 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1164 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1165 returns 'malformed search term' otherwise.
1167 SortResponse member resultCount now set to NULL in sort handler of
1170 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1173 Add three new utility functions for translating OIDs between various
1174 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1175 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1176 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1177 char *oid_to_dotstring(const int *oid, char *oidbuf);
1178 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1180 Reverted modifications for ES Update definition for z_IU0Update
1181 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1182 is back to YAZ 2.0.2.
1184 String value attributes for CCL parser.
1186 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1187 which their FirstSearch server returns in Init responses, sometimes
1188 carrying useful diagnostic information when Init fails. This has the
1189 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1190 "z39.50/oclcui.asn", where its definition is somewhat different from
1191 what OCLC document on their web-site, as required to interoperate with
1194 Support for anonymous authentication in yaz-client. Use the command
1197 * Fix the OID of the Index Data-local "admin" Extended Service from
1198 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1199 the 1000, which indicates a locally-defined OID, was a mistake.
1201 --- 2.0.3 2003/06/20
1203 Fix CCL directive @case handling so that it affects string match for
1204 both CCL keywords and qualifiers.
1206 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1207 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1208 Decoder has been updated with ASN.1 changes as listed in
1209 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1210 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1211 z_IUUpdate, remains unchanged.
1213 ZOOM_record_get may now return a record in a specific character set.
1214 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1215 "from" is the character set of record as returned by target. "to" is
1216 the character set to be returned. If omitted, "to" is UTF-8.
1218 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1220 New ODR utility, odr_getelement, which returns name of element for
1221 which encoding/decoding failed.
1223 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1224 in cases where a required element was omitted.
1226 Bug fix: some MARC8 sequences were not converted.
1228 New ZOOM option "step" which specifies number of records to be
1229 retrieved in one chunk. Used in conjunction with "start" and "count".
1231 SRW support for yaz-client. Use scheme http: to use it, e.g.
1234 yaz-client no longer does (un)intelligent character set conversions
1235 by default. Can be enabled with charset and marc_charset commands.
1237 xmalloc trace fix for 64-bit systems such as DEC alpha.
1239 Solaris 2.6 compile fix.
1241 New function, cql_strerror() translates SRW error codes, as returned
1242 by cql_transform_error(), into human-readable English strings. Used
1243 in yaz-client diagnostics when appropriate.
1245 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1246 converts it into a type-1 query which is sent to the server. This
1247 makes CQL available for use with all Z-servers, as opposed to the tiny
1248 minority that can handle CQL queries themselves.
1250 --- 2.0.2 2003/04/28
1252 New Debian package layout similar to the Redhat Package layout.
1254 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1255 and search result respectively.
1257 --- 2.0.1 2003/04/25
1259 Redhat package is now several packages: libyaz (runtime libraries),
1260 libyaz-devel (development and documentation, and yaz (utility programs).
1261 Package spec file by Morten Bøgeskov.
1263 New member 'schema' in struct bend_fetch_rr which the name of requested
1264 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1265 handler MAY set this to reflect the schema of the returned record.
1267 New member 'display_term' in struct scan_entry. GFS now sets member entries
1268 and allocates scan entries to be filled by user scan handler. In previous
1269 version, entries member was allocated by the scan handler. That still works,
1270 but the GFS will ignore member display_term - assuming it was NOT set by
1271 the handler. The fact that the GFS now allocates the entries both allows
1272 for new members and makes a scan handler easier to write.
1274 Fix CQL lex buffer overflow.
1276 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1277 SRU default recordPacking is string.
1279 SRU protocol support for frontend server.
1281 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1283 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1285 Added scan for the ZOOM shell (zoomsh).
1289 * String Identifers for Schemas (Amendment 5).
1290 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1291 Old definition for schema
1292 Odr_oid *schema; /* OPT */
1297 Z_InternationalString *uri;
1298 #define Z_Schema_oid 1
1299 #define Z_Schema_uri 2
1302 * resultCount parameter to Sort Response (Amendment 1).
1303 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1305 Support for SRW 1.0 over HTTP. This is an optional feature and
1306 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1309 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1310 on the same port. SRW SearchRetrieveRequests are mapped
1311 to bend_init,bend_search,bend_fetch,bend_close.
1313 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1315 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1316 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1318 ZOOM connections are SRW based if schem http is used for hostname
1319 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1320 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1322 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1323 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1324 distance=n, order=true/false, relation=le, prox unit=word. If
1325 n is omitted, distance 1 is used.
1327 Fixed problem with C compiler include path in wrong order.
1329 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1330 on Solaris. Patch from Ko van der Sloot.
1332 New MARC decode API. All new functions operate on a yaz_marc_t
1333 handle. The most important new functions are: yaz_marc_create,
1334 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1335 decode and destroy respectively. Decoder can produce formats
1336 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1337 include/yaz/marcdisp.h.
1339 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1340 to UTF-8, UCS-32, wchar_t or Latin-1.
1342 * Prototypes for yaz_iconv_-functions moved to separate header
1343 include/yaz/yaz-iconv.h.
1345 Make a few private functions 'static' in unix.c. This prevents
1346 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1348 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1349 are set when Init Response is received.
1351 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1352 but returns diagnostic set as well.
1354 New function yaz_strerror which is a portable wrapper for
1355 strerror/strerror_r/GetLastMessage.
1357 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1358 is returned for MARC. If type is "oai", then OAI MARC is returned.
1360 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1363 --- 1.9.2 2002/11/26
1365 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1367 Fix bad race conditions on SIGTERM and terminate gracefully in
1370 Move retrieval (data1) module to Zebra since nobody seems to be
1373 Add GRS-1 render for ZOOM using same format as yaz-client.
1375 --- 1.9.1 2002/10/05
1377 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1379 Fix broken ESpec handling in data1 module.
1381 SGML reader parses comments and makes them part of the data1 tree.
1383 Added several type casts so that YAZ compiles as C++ code.
1385 ZOOM didn't handle PDU encoding failures properly.
1387 Added more Bib-1 diagnostics (approved extensions).
1389 GNU configure: better check for iconv.
1391 More portable use of accept, getpeername. Check for socklen_t. Use
1392 int/size_t if socklen_t is not defined.
1396 PQF parser rejects bad queries - including those with extra
1397 characters in them. PQF parser used to silently ignore that.
1398 Cleaner API for PQF added, which allows you to get detailed
1399 error information for bad queries (see yaz/pquery.h).
1401 Fixed bug in ZOOM_record_get for type "database".
1403 Implemented mini iconv library supporting conversions between
1404 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1406 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1408 --- 1.8.9 2002/08/20
1410 Fixed ZOOM C record cache so that preferredRecordSyntax and
1411 elementSetName is used to check for already fetched records.
1413 --- 1.8.8 2002/08/02
1415 Added three members in bend_initrequest structure to facilitate
1416 character set negotiation.
1418 Fixed a bug in frontend server that could cause indefinite
1419 loops under rare conditions.
1421 Revised character set utilities (charneg.h) so that encoding
1422 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1424 For PQF, directive @term <type> sets term type for Scan/Search.
1425 Here <type> is general, string, numeric, null. The term type
1426 is inherited - just like @attr.
1428 New call odr_set_charset that sets character set conversion for
1429 international-strings on a ODR stream. Prototype is:
1430 int odr_set_charset(ODR o, const char *to, const char *from);
1431 The InternationalString is still represented as C string in YAZ
1432 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1433 won't). On the protocol level, you can use any encoding.
1435 Support for UNIX sockets in ZOOM.
1437 Solaris recv sometimes returns errno == ENOENT. It is treated as
1438 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1440 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1441 both client and server. Code by Morten Bøgeskov.
1443 --- 1.8.7 2002/05/22
1445 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1446 that they can be used directly from Visual Basic. You must recompile
1447 your windows APP if you're using ZOOM.
1449 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1450 Commands "lang" and "charset" sets language and character set respectively.
1451 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1452 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1454 Attributes from multiple CCL fields may be OR'ed rather than merged
1455 using directive "@field or". Fields are still merged by default -
1456 equivalent to "@field merge".
1458 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1461 Fixed bug in zget for parameter ExtendedServicesResponse.
1465 --- 1.8.6 2002/03/25
1467 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1469 Client displays USR.1:SearchResult-1 (hits per term).
1471 Additional Search Info for search in Generic Frontend Server.
1473 Fixed CCL parsing of "field=s".
1475 WIN32 installer - using the excellent NSIS software from nullsoft.
1477 Fixed CCL parsing of "field = - <number>".
1479 Added function yaz_marc_decode that decodes MARC for line mode
1480 display or XML (similar to that used by JZKit).
1482 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1483 Z39.50. But ISO/ILL was, however.
1485 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1486 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1488 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1489 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1491 --- 1.8.5 2002/02/03
1493 New YAZ client features: Command completion and new commands:
1494 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1495 Code provided by Jacob Poulsen.
1497 New call oid_trav, that visits all registered OIDs via callback.
1499 Function ZOOM_record_get now returns const char pointer rather than
1500 void pointer. It saves a lot of type casts.
1502 For YAZ client, command "auth" now allows you to set authentication
1503 in IdPass style. It is enabled when three tokens are given - order
1504 is user, group and password.
1506 Fix memory leaks in MARC record handling for ZOOM.
1508 New option for YAZ client, -k <kilobytes> that sets
1509 maximum record size. Similar to -k option for generic frontend
1510 server and yaz-ztest.
1512 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1514 Prefix query parser reports "fail" when bad attribute set is given.
1516 Fix in MARC decoder. Proximity logging. Fix for attribute set
1517 in scan handler for server. Patches by Shigeru Ishida.
1519 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1522 Configure option --with-openssl=<dir> now works when a directory is
1523 specified. Patch provided by Morten Bøgeskov.
1525 New option for YAZ client, -u <auth>, that sets authentication.
1527 ZOOM fix: error information was sometimes "missing", since error
1528 was cleared/reset too when it shouldn't.
1530 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1532 --- 1.8.4 2002/01/04
1534 Scan for ZOOM API. New object ZOOM_scanset. New functions
1535 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1536 ZOOM_scanset_destroy.
1538 New ZOOM function, ZOOM_connection_last_event, that returns type
1539 of last event (such as "receive data", "send data", "apdu received",
1542 New ZOOM option, schema, that specifies schema for retrieval.
1544 New CCL feature. Qualifiers can be aliases for one or more
1545 other qualifiers (if more than one is given, OR is used).
1547 ZOOM uses named result sets if target supports it.
1549 Two new YAZ client commands: . (dot, which sources a script of YAZ
1550 client commands), and ! (to execute shell command.). Implemented
1553 Working on Debian packages.
1555 --- 1.8.3 2001/11/19
1557 YAZ client enables named result sets only if target supports it.
1559 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1561 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1562 with key="host" to get same result.
1564 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1565 Function Z3950_resultset_record(s) returns references to records
1566 "owned" by resultset. To become owner use Z3950_record_clone.
1568 Function z_ext_record handles Extended Services. Thanks to
1571 --- 1.8.2 2001/11/12
1573 CCL Parser fix: ignore token comma when dealing with and-lists.
1575 Documentation updates for COMSTACK.
1577 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1578 Changed prototype Z3950_records. For some functions, int parameters
1579 were changed to size_t.
1581 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1584 New MARC decode/display function, marc_display_exl, which properly rejects
1585 non-ISO2709 records. YAZ client uses it.
1587 --- 1.8.1 2001/10/29
1589 Fix bug: local attribute set wasn't set correctly in PQF strings.
1593 * Old Z39.50 codecs no longer supported.
1595 Added ZOOM C binding. See http://zoom.z3950.org/
1597 Renamed states for COMSTACKs to avoid confusion with events.
1599 Implemented cs_look and proper cs_rcvconnect.
1601 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1603 Configure detects POSIX threads on OpenBSD.
1605 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1606 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1608 When error is returned from present handler, non-surrogate diagnostic
1609 is returned in present response (and fetch handler is no longer called).
1611 * Minor adjustments to pquery parser (PQF). Token characters may be
1612 escaped by using backslash (C-style).
1614 PQF parser allows string attribute values to be specified. For @attr,
1615 non-numeric characters after the equal-sign are treated as strings
1616 (e.g. @attr 9=title).
1618 CCL trunction character may be defined (@truncation in file)
1620 * function zget_ExtendedServicesRequest sets waitAction to
1621 waitIfPossible (was wait).
1623 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1626 CCL operator names may be set in field definition files (CCL_bibset).
1627 See ccl/bib1 for an example.
1629 Fixes in ASN.1 compiler for C++ compatibility.
1631 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1632 and "op_or" to avoid conflict with C++.
1634 Fixed problem with GNU readline detection on Redhat 7.0.
1636 Added step-size for Scan backend handler.
1638 Fixed bug that made the frontend server crash when no attribute
1639 set was specified for scan.
1641 Front-end server automatically switches to original working directory
1642 when installed as an NT service. Previously -w had to be specified to
1645 Added extended attributes for retrieval module (data1), so that data1
1646 records carry d1_readXML/SGML attributes. d1_read also supports
1647 null-data rules ( <tag/>)
1649 On UNIX when POSIX threads are available, a separate library libyazthread
1650 is created. Programmers should link with that library and the yaz library
1651 when using threads. The reason for the split was that some applications
1652 on Linux, such as Apache, doesn't work well when using shared objects that
1655 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1656 (or any frontend server) in SSL mode by specifying ssl: followed by
1657 address. Only tested on UNIX.
1659 Added feature for CCL module. Virtual structure s=al or s=ol generates
1660 and-list and or-list respectively instead of phrase search.
1664 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1665 log_mask_str. This was done to avoid name conflicts with other libraries
1666 (such as other PHP extensions).
1668 Added raw OID member for preferred record syntax (request_format_raw)
1669 and returned record syntax (output_format_raw) for backend fetch method.
1671 Config file yaz-config now accepts options so that it returns specific
1672 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1674 Shared library support for UNIX using GNU libtool.
1676 * Modified backend interface. Request/Response struct's replaced by
1677 one read/write C struct. For example bend_fetchrequest and
1678 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1679 Every handler - even search has to be registered in bend_init
1680 handler. This means that the YAZ library no longer refers to
1681 external functions and it makes it possible to make the whole
1682 thing a single DLL/SO.
1684 Added Segment handler for backend server.
1686 Added Zmbol/Zebra administrative functions to YAZ client.
1688 Threaded frontend server on UNIX (when POSIX Threads are available).
1689 Starting the server with option -T enables multi-threading.
1693 Added configure option --enable-comp/disable-comp to control use
1694 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1695 located in sub directory asn.
1697 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1698 in ${exec_prefix}/bin along with the other programs yaz-client and
1701 GNU automake used to maintain makefiles.
1703 Added several OID's.
1705 Changed retrieval module so that we can load records with no abstract
1706 syntax defined. Tagpaths in these records are fully composed of string
1709 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1713 On UNIX, the generated makefile now supports a proper 'make install'.
1714 The prefix can be set via GNU configure to set the install location
1715 (default is /usr/local).
1717 * YAZ programs client and ztest were renamed to yaz-client and
1718 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1719 locations, such as /usr/bin,/usr/local/bin,etc.
1721 * YAZ Header files were moved from include to include/yaz. YAZ Header
1722 files are referred to as include <yaz/log.h> rather than <log.h>.
1723 The YAZ include path (-I ..) is therefore the same as before. Programmers
1724 should update their #include statements or use -Ipath/include/yaz
1725 instead. The main motivation for doing this change is that YAZ header files
1726 can be installed in "standard" locations /usr/include,/usr/local/include
1727 without introducing conflicts, since ALL YAZ header files are stored
1728 in subdirectory yaz (under /usr/include for example).
1730 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1731 rather than project/workspace files. We switched because project files
1732 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1735 Changed name of logging function, logf, to yaz_log, to prevent name
1736 clash with some math-log functions. The YAZ header log.h defines logf
1737 to yaz_log (#define) so there should be no incompatibilities by this
1740 Added bend_start/bend_stop handlers for server. These handler are
1741 called on start/stop of server. For windows they are called whenever
1742 a service is started/stopped.
1744 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1745 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1746 in util/yc.tcl. The auto-generated C code structures are, in a few
1747 cases, incompatible with the old decoders. There are differences in the
1748 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1749 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1750 The preprocessor variable ASN_COMPILED is defined when the compiled
1751 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1752 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1753 wish to use the old encoders/decoders you can specify --disable-yc
1756 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1757 version so that it supports both new - and old version of DB Update
1759 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1760 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1761 change. The name parameter can be set to 0 in which no name is specified
1762 for the construction. The macros odr_implicit and odr_explicit sets name
1763 parameter to zero for the construction involved. New macros
1764 odr_implicit_tag and odr_explicit_tag are similar to the others,
1765 except that a name parameter is added. For programmers' that don't use
1766 ODR they probably only need to change the call to z_APDU and z_External.
1768 Added access control facility by interfacing the TCP wrapper library.
1769 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1770 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1771 name of the daemon and enables the access control as specified in
1772 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1774 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1775 den Dool <H.M.vdnDool@kub.nl>.
1777 Added reference ID parameter to most functions in server API - refer
1778 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1780 Changed name of ccl library to libccl.a (was ccl.a).
1782 Fixed bug in decoder for Explain (Category TargetInfo).
1784 Added support for GNU readline in client. Thanks to Jacob Poulsen
1785 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1787 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1788 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1789 IMPLEMENTATION! This change was made to the development version before
1790 the ZIG decided to retract the amendment. If any users MUST be
1791 compatible with the original Update definition, PLEASE CONTACT US, and
1792 we will include a separate definition corresponding to the old Update
1793 ES. Note that because of the change to the ASN.1 of the
1794 TaskPackageRecordStructure we cannot define a single structure that
1795 will support both versions.
1797 * Added const modifier to buffer parameter for some ODR/BER encoding
1798 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1799 completeWAIS, odr_dumpBER.
1801 Fixed bug in client.c which caused a crash when a scanResponse didn't
1802 contain positionOfTerm.
1804 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1805 * will cause an error in a client if a non-YAZ target sends both a
1806 * list of Scan entries and non-surrogate diagnostics.
1808 Retrieval module enhancements. Tag sets may be typed in the reference
1809 to it. From the .abs-file the "tagset" directive takes a third optional
1810 integer type for the tag set referenced. From a .tag-file the "include"
1811 directive takes a third optional type as well. The old "type" directive
1812 in the tag set itself is still recognized but acts as the default type
1815 Backend interface change. Individual Scan terms returned from bend_scan
1816 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1817 in include/backend.h.
1819 Retrieval module enhancements. Multiple tag sets and attribute sets may
1820 be specified in abstract syntax specs. Revised the error/warning for
1821 logging messages reported by the retrieval module when reading the
1824 Object Identifier system (oid_..) changed. The API is backwards
1825 compatible but the oid-routines now allocates new OID's when needed.
1826 Raw OID's may be specified in oid_getvalbyname.
1828 YAZ now uses GNU configure to generate Makefile(s).
1830 * Minor changes in some of the member names of DeleteResultSetRequest and
1831 DeleteResultSetResponse. See include/proto.h.
1833 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1834 and added member 'languages' in TargetInfo (which was missing).
1836 Changed the way attribute sets are handled in the retrieval
1837 module. These are now cached, just like the abstract syntaxes
1840 Changed YAZ so that it links with compiled ASN.1.
1842 Added Explain-schema definitions and mapping routines. The following
1843 Explain categories have been implemented: AttributeDetails,
1844 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1846 Fixed minor bug in Windows version of Server Library.
1848 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1850 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1852 Added EXTERNAL: UNIverse Resource Report (non-standard).
1854 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1855 ENUMERATED and SET OF.
1857 * Added 'const' to some of the char pointer arguments for the
1858 functions, data1_read_node, data1_getelementbytagname,
1859 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1862 Fixed bug in data1_insert_taggeddata - the last_child member of
1863 parent wasn't initialised.
1865 * Changed data1_read_record and data1_read_node so that the supplied
1866 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1867 doesn't refer to any parts of the "SGML"-buffer.
1869 Fixed bug in server library (Windows version of statserv_remove).
1871 * Changed code so that it compiles as C++. The type definition
1872 of Odr_fun which is a member of Odr_arm was changed. The result is,
1873 that an explicit typecast is needed for the fun pointer when
1874 using Odr_arm - as in:
1875 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1877 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1879 Implemented the new structured date and time definition as approved
1880 by the ZIG. Added schemaId element to the specificTag in Espec-1
1881 (also approved at the last ZIG). Thanks to RVDM.
1883 Added some Object identifiers (RVDM).
1885 Changed the Update Extended Service (RVDM).
1887 Added command "refid" to client which specifies referenceId for
1888 the following requests.
1890 Implemented extended service handling for server. See ztest.c
1891 for an example as well as backend.h. New handlers are registerd
1892 in the Init handler.
1894 * Changed interface for sort in server.
1896 Added new members to statserv_options_block. It allows a server
1897 to read options from another source than just the command line. Thanks
1898 to Charles Woodfield.
1900 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1901 renamed to zboolean. Some C++ compilers complained about the name.
1903 Minor changes to gils.abs. Added index 's' (sort) on title
1904 and date/time-last-modified.
1906 --- 1.4pl2 1998/1/30
1908 Fixed bug in server library regarding inetd mode (-i). This bug
1909 was introduced by release 1.4.
1911 --- 1.4pl1 1998/1/29
1913 Added sort facility in client and backend server interface.
1915 Fixed problem with dependencies in Makefile(s).
1917 Fixed bugs for encoders/decoders of extended services and
1920 Implemented sub-tree feature for schemas. Sub-trees are
1921 referenced in *.abs-files. See explain.abs for an example
1922 of the use of this feature.
1924 Modified bib1.att; local attributes for ANY didn't include
1925 ANY itself (only affects use of the retrieval module).
1927 Fixed bug in plain SGML reader in function data1_read_node:
1928 tags with prefix "var" was incorrectly interpreted as variants.
1930 Added feature "sub-schemas" to enable references to - and definitions
1931 of - group of elements.
1933 * Removed member parent from type data1_element (in data1.h).
1935 Implemented function odr_nullval() that returns the value of
1938 * Removed member num_children from data1_node (in data1.h).
1940 Made NT service interface part of the server library. The
1941 function statserv_main uses the NT service when required and
1942 calls the statserv_start / statserv_close routines.
1944 Routine zget_SearchRequest and zget_PresentRequest fills
1945 resultSetName/Id member with "default" instead of "Default".
1947 Fixed memory leak in server. Request queue member wasn't freed.
1949 Fixed nmem_exit so that memory is freed.
1953 Revised the CCL parser utility to be thread safe.
1955 Added function, oid_ent_to_oid, to replace the function
1956 oid_getoidbyent, which is not thread safe.
1958 * Added nmem_init and nmem_exit to initialize and release
1959 NMEM resources. Function nmem_init should be called once in the
1960 initial thread before NMEM/ODR is used. statserv.c and client.c
1961 have been changed accordingly. The change was necessary to make
1962 NMEM thread safe. The NMEM memory pool is shared amongst threads
1963 in a process. Unix-based applications will still work fine without
1966 Added NT Services interface for the the Z39.50 (statserv) Server.
1967 Refer to the ztest.c source on the usage.
1969 Windows 95/NT port using MSVC5.0. Project files are included in the
1972 * Defined new 'global' handle for the retrieval (data1) system. The
1973 new handled, data1_handle, describes the state of the data1 system.
1974 This handle is passed as first argument to virtually all
1975 data1 related routines. The functions data1_create and data1_destroy
1976 creates and destroys a data1 handle respectively.
1978 Added ODR encode stream member to all backend request structures
1979 init, search, scan etc. This stream should be used to allocate all
1980 memory used for the response when thread safe operation is needed.
1982 Changed the comstack utility, cs_addstr, to be thread safe. The
1983 returned hostname string returned by the function is now part the
1986 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1987 function. The cs_straddr takes a COMSTACK handle as argument, so this
1988 function must be used after cs_create and before bind/connect.
1989 This function is thread safe.
1991 Moved test server to 'ztest' directory - generic server code still
1992 in 'server' directory.
1994 Made prefix query (pquery.c) utility thread safe.
1996 Added new function modifier YAZ_EXPORT to 'export' public DLL
1997 functions when using windows (see include/yconfig.h).
1999 Added definitions to the OID database (util/oid.c) (RVDM).
2001 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2003 Added call to ccl_rpn_delete in client program.
2005 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2006 release of RPN structure.
2008 Added support for C++, headers uses extern "C" for public definitions.
2009 With input from RVDM.
2011 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2012 Thanks to Ronald van der Meer (RVDM).
2014 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2016 Added support for private extensions to the OID database
2017 (oid_setprivateoids()). Thanks to RVDM.
2019 Added optional, physical ANY (key replication)
2021 Fixed null-reference problem in GRS-1 output filter.
2023 Proximity operator added to Prefix Query Format (PQF).
2025 In test client command "base" accepts multiple databases.
2027 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2031 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2033 Smallish bug-fixes in the new encoders/decoders (explain).
2035 Bug fixed in DeleteRequest.
2037 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2039 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2041 Added SOIF syntax (using private OID for now) to retrieval module and client.
2043 Added Update extended service.
2045 Added SearchResult-1 additional info structure.
2047 Added optional CCL (ISO8777) interpreter as separate module. Available
2050 --- 1.2 1996/6/10 (1st anniversary release)
2052 Added Summary record syntax. Lightly tested.
2054 Added OPAC record syntax. Untested.
2056 Added ResourceReport service encoders/decoders. Untested.
2058 Fixed bug in z_Unit - wrong tagging on unitSystem.
2060 Fixed bug in the DiagRecs decoder.
2062 Added options for max PDU size and session timeout to frontend-server.
2064 Added documentation of query-language parsers and other supporting utilities.
2066 [frontend-server] Added Attribute set to the bend_scanrequest API.
2068 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2069 surrogate diagnostics were generated.
2071 [retrieval] Allow multiple local values for attribute.
2073 [retrieval] Allow multiple attributes per element in .abs files. index type.
2075 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2077 --- 1.1pl2 1996/4/10
2079 Minor changes, mostly specific to Zebra's requirements (retrieval)
2083 Repaired bug in frontend server when running multiple listening
2084 endpoints in dynamic mode.
2086 z_External() now won't break if a known, ASN.1 value comes encapsulated
2087 in an octet-string. The value will pass through unmodified in an Odr_oct.
2089 Added a bit of code to the demo client to decode & display
2090 ASN.1-structured records represented in the octet-aligned branch of
2091 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2093 Added z_ext_getentbyref() to the ASN module. Doc updated.
2095 * Completed the SCAN definition in the ASN module. This may break SCAN
2096 code based on older YAZ-versions at compile-time. The fix is easy -
2099 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2100 under the SCAN definition. Remember to initialize this, server-people.
2102 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2103 that this does not extend to ODR and ASN.
2105 Comstack allows insertion of established socket (primarily for
2106 inetd-operation of servers). Doc updated.
2108 Front-end server can now start from the inetd in TCP mode. Doc
2111 --- 1.0pl4 1996/1/24
2115 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2116 the rank and record number.
2118 Adjustments to the frontend server.
2120 Fixed diagnostic BER dumper. It ignored the file argument.
2124 Various changes to retrieval module.
2126 Changed the union discriminators of the protocol files from enums to
2127 ints paired with #defines.
2129 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2132 *Changed operator in the RPN structure to 'roperator', again to avoid a
2135 Fixed problems in Explain decoders/encoders.
2137 --- 1.0pl2 1995/12/6
2139 Memory bug in log module fixed.
2141 --- 1.0pl1 1995/12/5
2143 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2145 Bug in Explain DatabaseInfo module fixed.
2147 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2151 The shift to v1.0 signals that we now consider the *core* functionality
2152 of YAZ reasonably stable (the core being more or less equivalent to
2153 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2154 tested (Explain not at all - though that will happen soonish).
2156 Minor changes to code to support Windows port.
2158 Various minor changes after we're getting to use GRS-1 & co. more.
2160 Added Espec-1 format.
2162 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2163 of the protocol and it cannot be selected when encoding (maps into 'string'
2164 when decoding). Needed to talk to some servers.
2166 Demo client can request simple element set names.
2168 Added Diagnostic Format encoders/decoders.
2170 Added simple Close handling to frontend server (no hooks for resource
2171 reporting yet), and demonstration client.
2173 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2175 --- 1.0b3 1995/08/24
2177 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2178 handled incorrectly when records were requested in the searchResponse. This
2179 will only affect you if you use the frontend-server.
2181 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2182 Test-client will ask for and print GRS1. Ztest will return dummy records
2185 Added Explain encoders/decoders to the service-level API. Untested.
2187 Added Extended Services: Item Order encoders and decoders to the Service-
2188 level API. Untested. We could use a recent copy of the pertinent bits
2189 of the ILL protocol to add those bits.
2191 Added diagnostic format 1 encoders/decoders to the service-level API.
2194 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2195 odr_cons.c, which causes a more correct output.
2197 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2198 was always set to 0 when no records were requested in the searchRequest.
2200 * Added better external-handling. This shouldn't harm old code that
2201 *encodes* externals. It can break code that looks for a
2202 'single-ASN1-type' representation, since those types that are known
2203 are now decoded immediately. Look at the SUTRS sample code in
2204 seshigh.c and client.c. Documentation updated.
2206 Handling of structured records in bend_fetchresponse. Length -1 marks
2207 structured record, type is deduced from format field.
2209 --- 1.0b2 1995/06/27
2210 Fairly quick maintenance release to add SUTRS support.
2212 Fixed handling of SUTRS records in the demonstration client.
2214 * Added format field to the bend_fetchrequest and bend_fetchresponce
2215 structures of the backend API (frontend server). When the record is
2216 returned, the value of the format field is mapped to an OID. The
2217 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2218 of the record. The special value VAL_NONE in the bend_request means
2219 that no specific format was requested by the client. Documentation
2220 updated accordingly. Test server (ztest) will return a fixed dummy
2221 SUTRS record if your client requests SUTRS.
2223 Documentation updated accordingly.
2225 You can now set external libraries and RANLIB support in the top-level
2229 First public release.
