1 Changed decoding of SRU XML packed records to deal with servers that
2 have recordData with XML data with multiple root nodes. Also make
3 comparison for recordPacking case insensitive. Again, one server
4 returns "XML" where others return "xml".
6 For SRU responses allow Content-Type application/xml as well as text/xml.
10 Fixed bug in character set conversion of BER strings. Bug introduced
15 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
17 For OID class, use oid_class consistently.
19 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
22 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
23 character set for bibliographic information interchange". By Giannis Kosmas.
25 Added documentation on new OID API.
29 Changes to generic frontend server interface: added new member
30 'query_charset' for bend_initrequest structure. A backend init handler
31 should set this member to its native character set for query terms.
32 When defined, the frontend server logic will announce this character set
33 to a client if the negotiationModel bit is set by the client. All server
34 implementors are encouraged to specify this. If a backend server does not
35 specify this a warning is issued using yaz_log(YLOG_WARN,..).
37 Added CCL utility to remove terms (stop words) from resulting RPN
38 tree. This is handled by functions with prefix ccl_stop_words_ .
40 New ZOOM C option, "rpnCharset", which allows client-side conversion of
43 Clean-up the CCL API. Moved some internal structures from ccl.h to
44 private header cclp.h. Changed ccl_parser_create so that a Bibset must
45 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
46 This is replaced by ccl_parser_find_str which takes a string instead.
48 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
49 libyaz.la is the core of YAZ except the generic frontend server and
50 does not depend on POSIX threads anymore. libyaz_server.la is the
51 generic frontend server facilities and uses POSIX thread functionality
52 if available. The libyaz.la no longer depends on POSIX threads because
53 the number of global structures is limited. NMEM no longer re-uses blocks
54 between threads ; it simply free's memory immediately but allocates in
55 "large" chunks as usual. We don't expect any performance penalties
56 because of this. The yaz_log system is still using a global log_level so
57 caution must be taken when modifying it with yaz_log_init_.. +
58 yaz_log_mask_str. This, however, should not cause any trouble because
59 these functions are called during initialization of application code
60 anyway. `yaz-config --libs server` returns libs for server applications;
61 `yaz-config --libs` returns libs for non-server applications.
63 New OID database - with public definitions in oid_db.h. Removed old OID
64 database including the head oid.h and definitions such as enum oid_value
65 and struct oident. The new OID database uses the same string names as
66 before but the 'protocol' is gone. There are now only two representations
67 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
68 converts from string to OID; functions with prefix yaz_oid_to_string
69 converts the other way.
71 Change to emit_term() in CQL-to-PQF query translation: when a term has
72 the /regexp relation modifier, do not process it for leading and
73 trailing "^" and "*", which have quite different meanings in regular
76 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
77 write handlers no longer carries a 'last' parameter. This will make
78 yaz_iconv flush "less" characters. A flush is performed by call to
79 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
81 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
82 removed, because function yaz_query_to_wrbuf does the same.
84 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
85 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
87 Deprecated MARC utility functions removed.
89 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
92 Branch split: YAZ_2_1_55_branch
96 Fix to ZOOM-C so that transparent reconnection is properly handled on
97 connections that are in asynchronous mode.
99 Fixed compilation on OpenBSD 4.0.
101 Large strings in GRS-1 records are now properly displayed in yaz-client.
103 Added character conversion support for "advancegreek"; based on patch from
106 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
107 sequence is met. Before the error was not set so it would be unknown.
109 Adjust yaz-marcdump MARC reader so that it skips until record separator
112 --- 2.1.52 2007/03/07
114 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
115 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
116 fd_set structure used as a bitmask for the FDs to be selected on.
118 Using ACX_PTHREAD macro to check for POSIX threads.
120 Fixed have-vsnprintf check.
122 --- 2.1.50 2007/02/23
124 Fixes for configure on BSD. Bug #900.
126 Added snprintf/vsnprintf wrappers for systems that don't have
127 limits (heavens forbid).
129 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
130 created before all previous tasks were completed and removed from the
131 task queue, the new task could be removed by a mistake.
133 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
135 Implemented pass-through CQL-to-PQF conversions. Bug #861.
137 Fixed bug #832: Problem with MARC/charset in yaz-client.
139 Fixed bug #668: save command line history for yaz-client.
141 Fixed bug #830: pkg-config support.
143 --- 2.1.48 2007/01/23
145 Extended ZOOM result set options with two options that may be read by
146 a client: resultSetStatus and presentStatus with values as specified for
148 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
150 Fixed bug #827: Using SSL fails on Debian etch.
152 Fixed bug #826: Weird looking chars for set of MARC records.
154 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
155 that is treated as an ItemOrder with itemRequest being an XML document
156 external. The value of "doc" is the content.
158 Extended the GFS search facility. New member of bend_search_rr
159 'estimated_hit_count' signals that hits is known to be an estmate
160 (higher or lower than real hit count). New member 'partial_resultset'
161 signals that the search was partial (hit count is lower or equal than
162 real hit count). For Z39.50, the information is stored in resultSetStatus
163 member of SearchResponse APDU. For SRU, the information is signalled
164 via SRU diagnostic 59: "Result set created with valid partial results
167 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
169 --- 2.1.46 2007/01/13
171 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
173 Added ZOOM_connection_peek_event.
175 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
176 the following new functions:
177 ZOOM_event_nonblock, ZOOM_connection_process,
178 ZOOM_connection_get_{socket,mask,timeout},
179 ZOOM_connection_fire_event_{timeout,socket}.
180 The existing blocking event handler, ZOOM_event, is a wrapper for the
181 + blocking ZOOM_event_sys_{poll,select}.
183 Implemented function ccl_xml_config which parses XML version of CCL
184 configuration (bug #798).
186 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
188 Added timings utility (yaz/timing.h)
190 --- 2.1.44 2007/01/03
192 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
195 Fixed bug #779: Rotation of apdu.log fails.
197 Fixed for character set conversions:
198 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
199 Honor G1 set in MARC-8 decoding.
201 --- 2.1.42 2006/12/17
203 Fixed bug #775: char conversion does not handle Alternative UTF-8
206 Implemented function yaz_marc_read_line which parses MARC line format
207 records. There is a wealth of formats out there. So far, this function
208 reads line records produced by yaz_marc_write_line.
210 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
211 more generic and easier to remember(!) options: -i format and -o format
212 which specifies input format and output format respectively - where
213 format is one of "marc", "marcxml", "line", "marcxchange".
215 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
216 does not print anything except warnings for records.
218 For yaz-marcdump, added support for MARC split into files (-s) with a given
221 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
222 spec, at http://www.loc.gov/standards/sru/record-update/
223 This has changed the binary layout of the following structs:
224 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
225 bend_update_rr . Patch by Ko van der Sloot.
227 Added GFS utility function bend_assoc_is_alive which returns 1 if
228 association is still alive (client is connected); 0 otherwise (client
229 closed connection). This allows busy servers to stop working for
232 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
233 been a separate piece of software. This version of ziffy has been modified
234 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
236 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
238 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
239 Client code may now interrogate options such as "init_opt_sort" to
240 find out whether the server claims to support various options.
242 --- 2.1.40 2006/11/27
244 Added utilities yaz_{set,get}_esn to set/get element set name from
247 Removed the build of libyazthread.la. The libyaz.so is the threaded version
248 of YAZ and has been so since YAZ 2.1.10.
250 Implemented ZOOM_record_error which returns error information for
251 record (surrogate diagnostic).
253 --- 2.1.38 2006/10/31
255 Updates for SRU Update by Ko van der Sloot:
256 1. Changed name from "operation" to "action"
257 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
258 versions in the code, marked as 'backward compatible'.
259 3. Added diagnostics for SRU Update.
261 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
263 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
265 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
267 For GFS, fixed problem with SRU diagnostic 'First record position out of
268 range' being issued for 0 hits.
270 zoomtst10 part of Windows Build.
272 --- 2.1.36 2006/10/13
274 Implemented yaz_filepath_comp which splits a path into file path
275 components (required by Zebra 2.0.3+).
277 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
278 BSD inspired license until now so this should not have any real impact on
279 anybody. See http://www.opensource.org/licenses/bsd-license.php
281 Fixed bug #687: Missing log lines.
283 Fixed bug #678: CQL to PQF translation does not preserve double-quote
286 Fixed bug #689: SRU diagnostics to be added.
288 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
289 whether a connection is idle (no more work do do).
291 --- 2.1.34 2006/10/04
293 Change type of optval from long to int for invocation of setsockopt with
294 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
296 Added support for specifying the max log file size for the Generic
297 Frontend Server. The size is given with option -r.
299 --- 2.1.32 2006/09/21
301 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
303 --- 2.1.30 2006/09/17
305 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
308 Fixed bug in Generic Frontend Server that could cause a server to stop
309 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
311 For the generic frontend server, the maximum record size is used as maximum
312 size of incoming packages (SRU + Z39.50). The value until was previously
313 only used in Z39.50 Init negotiation and, later, in a session controlled
314 sizes of records returned. This is controlled using -k option. It can be
315 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
317 --- 2.1.28 2006/09/04
319 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
322 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
324 New option for yaz-marcdump -lpos=value which allows setting a portion
325 of MARC header to a certain value.
327 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
329 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
330 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
332 --- 2.1.26 2006/08/15
334 Fixed problem with SRU mode type (soap, get, post) for yaz-client
337 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
339 --- 2.1.24 2006/08/08
341 Fixed MARC ISO2709 encoding routines to deal with character set
344 Minor changes to GFS logging. Database included in search request log
347 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
348 cached/multiple records.
350 Shared libraries are built by default on Unix+configure.
352 Changed cql2pqf transformation to use a different evaluation order. The
353 new order is: always, relation, structure, position, truncation, index
354 and relationModifier. Old order was: always, relation, relationModifier,
355 structure, index, position, truncation. Note that the the latter ones
356 override former ones for identical attributes.. The new scheme means that
357 it is possible to override any existing attribute with a relationModifier.
358 And also that it is possible to override everything for the index rule
359 (except the ones listed in relationModifier). No order is perfect but this
360 one, we believe, covers more real cases.. The "always" should have been
361 called "default", since the attributes there can be overridden with all
364 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
365 compilation phase, but also for yaz-config --cflags output. This allows
366 us to have public headers with Libxml2 stuff in them . It should also,
367 eventually, make Libxml2 checks redundant in packages using YAZ, such
370 --- 2.1.22 2006/06/15
372 Changed SRU update structure bend_update_rr so that SRU diagnostics are
373 stored in uri, message and details.. Previously diagnostics were stored
374 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
375 compatibility.. but he's probably the only one affected, so.
377 Added support for CCL, compiled on the client side, in ZOOM-C. This
378 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
379 input; the resulting query objects can be used for for searching with
380 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
382 YAZ' configure searches for OpenSSL by default.
384 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
385 SL_CTX_use_certificate_file. See
386 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
387 for more info. Thanks to Ko van der Sloot.
389 --- 2.1.20 2006/06/02
391 Bug #600: SRU GET, POST support for yaz-client. Introduced
392 command 'sru' which selects method SOAP/GET/POST.
394 Allow missingValueAction to be specified for the sortspec string -
395 function yaz_sort_spec. By default, the missing value action is null.
396 Use ! to specify "abort". Use = followed by stringvalue to specify default
399 Ensured that Present-handler (if defined) is called in GFS before any call to
400 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
401 searchRetrieve requests.
403 Documentation for YAZ is now based on the Docbook XML/XSLT using
404 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
405 is no longer depending on jade/openjade or docbook-to-man scripts.
406 PDF is no longer part of the distribution - but can optionally be
407 made using DSSSL/jadetex or FOP.
409 Added retrieval handling support in Generic Frontend Server to support
410 conversion between MARC/XML as well as XSLTtransforms. See
411 etc/yazgfs.xml for an example.
413 Added Authentication support to Generic Frontend Server in SRU
414 mode. Authentication using HTTP Basic is supported, as is the use
415 of 'x-username' and 'x-password' parameters in the request itself.
417 Added support for a new character set MARC8s identical to MARC8 except
418 that it converts combined characters to single Unicode characters in the
419 Latin-1 range (when possible).
421 --- 2.1.18 2006/04/24
423 ASN.1 compiler 0.4: generates brief Doxygen file header for
424 generated .h/.c files.
426 Utility yaz_iconv now supports conversion to MARC-8.
428 New facilities for the MARC module. The reading - and writing of
429 content are separate methods for the yaz_marc_t handle. The following
430 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
431 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
432 format). Write functions have prefix yaz_marc_write_.. The existing
433 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
434 available. Removed support for OAI-MARC and simplexml (not the
435 simplexml from PHP5).
437 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
438 to be returned for this connection.
440 --- 2.1.16 2006/03/31
442 Allow multiple languages and charsets to be specified with
443 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
444 negcharset iso-8859-1,utf-8
446 Translation of proximity nodes from CQL into PQF now works.
448 Moved to automake 1.8, 1.9.
450 Added function yaz_log_set_handler which allows a log handler to be
451 installed. This handler will be called for all log messages. Output
452 to file is also produced; but that can be disabled by passing NULL
453 fname to yaz_log_init_file.
455 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
457 For SRW (including GFS), accept application/soap+xml as content-type
460 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
461 produces NO stylesheet reference even if a default stylesheet is specified
464 --- 2.1.14 2006/03/14
466 Updated Windows package to include yazd.dll + yazd.lib for the
467 Development component.
469 If the environment variable YAZ_LOG is set, then it is used as a
470 string indicating the default level of logging to use if not
471 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
472 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
473 used as before. So, for example, to omit warnings from YAZ logging,
476 cql_transform() now map structure and other attributes before indexes,
477 so that index-specific structures and other attributes can override
478 defaults. So now a combination of mapping specifications such as:
480 index.dc.date = 1=date-modified 4=5
481 does the right thing.
483 cql_transform() now also respects the "always" mapping specification,
484 which establishes an initial set of attributes to be used for all
485 terms except where overridden by more specific attributes associated
486 with the index, relation or modifier.
488 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
489 which mode to use; one of "post", "get" or "soap" (SRW, default).
491 Fixes for yaz_iconv routines: changed trie-based character set conversions
492 to use only non-negative values for bit fields due to Sun's C compiler not
493 supporting negative values.
495 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
496 sequences where not read correctly. Fix by Rustam Usmanov.
498 Updated win/makefile to use options, settings which makes things
499 compile with VS C 2005.
501 --- 2.1.12 2006/02/01
503 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
505 In ZOOM socket code, use select instead of poll on MacOSX.
507 ZOOM-C now support client-side compilation of CQL into RPN that is
508 sent to the server, enabling CQL to be used against all Z39.50
509 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
510 ZOOM_query object, and submit it using ZOOM_connection_search().
511 The CQL-to-RPN translation uses a configuration file, the name of
512 which must be specified in the Connection's "cqlfile" option.
514 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
515 function, which takes as its start-term parameter a ZOOM_query object
516 (which may have had either CQL or RPN set into it).
519 --- 2.1.10 2005/11/29
521 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
522 GFS to support this as well. Backend handler, bend_srw_update, does the
523 update work. Code contributed by Ko van der Sloot.
525 Allow retrieval of Search Result-1 information in ZOOM by the use of
526 options that are attached to a result set. ZOOM documentation updated
529 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
530 UTF-8 conversion. Patch by Raj Patel.
532 Added option -m to GFS to control formatting of timestamps in log file.
534 Added 'exit' as synonym for 'quit' in yaz-client
536 Added support for specifying SRW resultSetId + resultSetIdleTime in a
537 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
538 for the new members. Patch by Ko van der Sloot.
540 Added support for SRU POST. It is supported for content-type
541 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
543 Do not build the separate Multi-threaded (MT) library libyazthread.la.
544 Instead make the library libyaz.la multi-threaded. Threading as a whole
545 can still be disabled by configure option --disable-threads. Previosly,
546 with older GLIBCs there were problems with MT libs under Apache. This
547 has now been fixed a long time ago.
549 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
552 CQL module modified to be case insensitive for relations/indexes/operations.
554 Fixed bug in CQL transform code: incorrect value relationModifieder
557 Added 'show all' command for yaz-client which retrieves all results
560 Added new yaz-client, xmles, which takes a (private) OID and
561 a document to be sent as an extended service request.
563 Describe new yaz-client commands wait_response and set_auto_wait.
565 Increase TCP/IP listener backlog from 3 (which I am guessing was
566 copied from the SunOS manual entry way back when) so SOMAXCONN, so
567 that the socket will queue as many incoming connections as it's able
568 to handle ongoing connections. In other words, it will never now
569 refuse a connection that it would be able to handle merely because
570 it's not got around to accepting() enough of the pending connections
571 yet. This is the behaviour anyway under Linux, where the listen()
572 argument is ignored; but not under BSD and on systems such as
573 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
574 YAZ-based servers should now be uniform across operating systems in
577 yaz-marcdump uses 64-bit file access on some systems. This is enabled
578 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
579 This allows yaz-marcdump to read large MARC batches (>2 GB).
581 Modified all YAZ source files - except the source which is auto-generated
582 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
585 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
586 corresponding to the existing *_setl() function. These allow option
587 values containing arbitrary valuues.
589 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
590 ZOOM_resultset_sort() in new applications. Its behaviour is identical
591 except that it returns an indicator of whether or not the sort
592 criterion was accepted (0 for OK, -1 for invalid).
596 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
597 MARC output rather than returning "new" buffer.
599 yaz-client warns about unknown init options.
601 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
605 Added support for SRW sort in Generic Frontend Server. Patch
606 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
607 sortKeys - or NULL if none is provided.
609 Fixed bug #307: It was impossible to specify indefinite/no timeout
610 for ZOOM_event. Special timeout value -1 now means indefinite timeout
613 Added support for multiple languages and charsets to be specified in
614 ZOOM. Each charset/language is separated by a blank. If negotiation is
615 in effect in init-response, Option
616 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
617 Code based on patch by Vasiliy Osadchuk.
619 Fixed bug #306: infinite recursion that occurred when calling
620 yaz_log_level_init as the first call (before other log level or
623 Fixed bug in scan handling in front end server: if preferred-Position-In-
624 Response was non-present, a NULL pointer referece was performed.
628 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
629 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
630 now defined for all those error codes. So instead of putting 109 in
631 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
632 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
634 Modified the yaz-marcdump utility to skip garbage bytes between MARC
637 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
639 Program yaz-client now exits and produces an error message if multiple
640 Z39.50 servers are specified on the command line (none or one allowed
643 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
648 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
650 Fixed bug #272: Preserve spacing for CCL terms.
654 Added support for virtual hosts and multiple backend servers for
655 the YAZ frontend server. The configution is XML based and
656 support specificition of CQL to RPN mappings and explain information.
657 See section "Virtual Hosts" in the YAZ manual.
659 Extended OPAC display utility. OPAC display utility renders
660 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
661 to supplement yaz_marc_decode_wrbuf.
663 Fixed a bug in MARC decoder that could caused it to crash for some
664 invalid MARC records. More diagnostics and warnings where added in
665 XML output (warnings, etc are stored in comments).
667 --- 2.0.34 2005/02/08
669 Fixes for UNIX domain sockets. Bug #261.
671 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
673 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
674 Added yaz_marc_subfield_str which defines subfield lead string which is
675 used in YAZ_MARC_LINE format. Default string is blank+$. Added
676 yaz_marc_endline_str which defines end of fields string used in
677 YAZ_MARC_LINE format. Default string is newline.
679 Experimental support for MarcXChange. This format can be produced
680 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
681 http://www.bs.dk/standards/MarcXchange.xsd
683 Added yaz-client commands scansize that sets maximum number of
684 entries to be returned by scan.
686 --- 2.0.32 2005/01/11
688 Added support for SRW scan in yaz-client and Generic Frontend Server.
690 * Added whereInList member to SRW Scan Term.
692 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
694 Fixed NMEM system to return aligned blocks on the smallest boundaries
695 that are suitably aligned for all possible types on the particular
696 architecture YAZ is being built for.
698 --- 2.0.30 2005/01/04
700 Fixed numerious warnings that was issued with newer versions of GCC.
702 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
703 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
706 Make YAZ Generic Frontend Server slightly faster.
708 Enhance (and reduce) logging for Generic Frontend Server.
710 Revert YAZ log system so that it flushes every write operation
711 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
713 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
714 instead of LOG_, due to name clash with syslog(3). LOG_ are still
715 present. New applications should define YAZ_USE_NEW_LOG=1 - this
716 will effectively disable old definitions.
718 --- 2.0.28 2004/11/09
720 Added yaz_log_time_format which specifies log format using
723 Added yaz_log_module_level which returns mask for a module. Value
724 is non-zero mask a if module is enabled; zero if disabled.
726 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
727 in include/yaz/cql.h.
729 Fixed bug #176: Dont throw diagnostics on empty SRU args.
731 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
733 Fixed bug #172: RPM builds does not enable SSL.
735 Doxyfile.in part of dist. Doxyfile generated by configure.
737 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
738 are given and the corresponding component does not exist.
740 Extend CCL documentation in YAZ reference. Describe r=r.
742 --- 2.0.26 2004/10/01
744 Fixed MARC->MARCXML conversion to properly deal with
745 fields, subfields, indicators having non-ASCII characters.
747 Fixed MARC->MARCXML conversion so that ASCII control characters
748 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
751 Added YAZ GFS support for conversion from Z39.50 surrogate
752 diagnostics to SRW surrogate diagnostics.
754 Bug fix: YAZ GFS did not return schema in explainResponse.
756 --- 2.0.25 2004/09/30
758 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
759 now converts recordSchema to elementSetName as well as schema URI.
761 Fixed bug in COMSTACK that prevented HTTP request packages from being
764 --- 2.0.24 2004/09/29
766 Added CCL facility r=r "range" which is similar to r=o "ordered" but
767 does not require white-space before and after the dash in a range, e.g.
768 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
771 Fixed a few AC_TRY_LINK configure tests that did not operate properly
772 due to new GCC removing "redundant" code.
774 Added yaz-client commands scanpos and scanstep that sets preferred
775 position and step-size for scan.
777 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
779 Added CCL utility ccl_qual_buf which parses one or more CCL
780 spec lines in a buffer.
782 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
783 of name and value - ignoring empty lines and comments.
785 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
787 Added odr_get_element_path which returns current element path for an
788 ODR handle. This utility is useful in error handling or user-defined
791 Added ODR_PRINT utility odr_set_stream which is is a more generic
792 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
793 to a write function and pointer to close function. The close function - if
794 non-NULL - will be called during odr_destroy.
796 Fixed bug in CCL parser where truncation char was not removed from
797 right side when truncation=both was in effect.
799 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
802 --- 2.0.23 2004/08/11
804 Fix buffer overrun in CQL parser when dealing with proximity (%).
806 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
807 to UTF-8/UCS conversion is now only based on codetables.xml.
809 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
811 --- 2.0.22 2004/08/06
813 Add support for more "commit changes" in ZOOM (uses Extended Services).
815 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
818 Yet another small fix for configure of SSL.
820 --- 2.0.21 2004/05/14
822 Fix SSL libs for configure when --with-openssl=DIR is given.
824 --- 2.0.20 2004/05/10
826 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
828 SSL comstack now uses yaz.pem certificate file on server side
829 by default. Certificate filename can be configured by calling
830 comstack function cs_set_ssl_certificate_file before cs_bind is used.
832 Fix bug regarding multiple calls to ZOOM_connection_connect.
834 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
836 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
837 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
839 ZOOM now allows inspection of X509 peer certificate for verification.
840 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
842 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
843 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
844 as "modular" but it simplifies things.
846 Added cs_get_peer_certificate to that returns peer X509 PEM.
848 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
849 NULL if SSL is unavailable.
851 Documentation about MARC decoding tools.
853 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
855 --- 2.0.19 2004/03/30
857 Rename CHANGELOG to NEWS to follow GNU style packing.
859 Fix bug with missing initialization of member in init_diagnostics.
860 This bug affects threaded version of GFS server.
862 --- 2.0.18 2004/03/20
864 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
867 Ensure zlib.dll is packed with Windows install.
869 --- 2.0.17 2004/03/17
871 Fix encoding of xsd:string to use text instead of CDATA.
873 Fix endless loop in CQL parser with unbalanced ".
875 Use a more compact way to store MARC-8 conversion tables.
877 --- 2.0.16 2004/03/16 Debian only
879 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
882 Update CQL parser to use new CQL 1.1 modifiers for booleans and
887 --- 2.0.15 2004/03/01
889 Another fix for decoding of XML packed records.
891 --- 2.0.14 2004/02/25
893 Fixes for Chunked encoding. White space not ignored after length spec.
895 Update NS and use default NS for SRW diagnostic elements.
897 --- 2.0.13 2004/02/23
899 Implement ZOOM_resultset_cache_reset which resets record cache.
901 Implement ZOOM_resultset_sort which sorts a result set.
903 Implement chunked HTTP transfer.
905 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
907 --- 2.0.12 2004/02/16
909 Added member 'schema' to bend_explain_rr structure so that backend
910 can specify explain record identifier. Defaults to Zeerex 2.0.
912 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
914 --- 2.0.11 2004/02/16
916 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
919 Added init command for yaz-client which sends "extra" init request.
921 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
922 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
924 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
926 Make ZOOM error code for "invalid query".
928 Fixed compilation for SSL which wasn't properly enabled for all platforms.
930 --- 2.0.10 2004/02/05
932 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
935 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
937 Added option -p <file> to make Generic Frontend Server to write PID file.
939 Added option -D to put Generic Frontend Server in background on its own.
941 Make ZOOM C recognize option "password". If unset, "pass" is used
942 (for backwards compatibility).
944 Fixed a bug in Generic Frontend Server that could make it crash if a
945 client sets characterSetNegotation bit, but didn't pass negotiation stuff
948 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
949 Must be issued before open, in order to be in effect.
951 --- 2.0.9-6 2004/01/12 Debian/Windows
953 Make the SRU server more picky WRT unknown params, etc.
955 Bug fix: ZOOM scan response didn't return displayTerm - when present.
957 New YAZ client command, options, that sets Z39.50 options.
959 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
960 options from a string of tokens (one token for each option bit).
962 Update SRW diagnostic code messages.
964 --- 2.0.9-5 2004/01/07 Debian/Windows
966 Handle user defined stylesheet for SRW/SRU.
968 --- 2.0.9-4 2004/01/06 Debian/Windows
970 Fix bug in decoding of Content-Length.
972 --- 2.0.9-3 2004/01/06 Debian/Windows
974 Fix a bug with decoding of XML packed records.
976 --- 2.0.9-2 2004/01/05 Debian only
978 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
980 Fix bug in SRW/SRU diagnostics decoding.
984 Fixed bug in Generic Frontend Server which could drop records exceeding
985 preferred message size. Reported and fixed by Irina Dijour.
987 Fixed calculation of package size for structured records in Generic
988 Frontend Server. Reported and fixed by Irina Dijour.
990 Fixed namespace for SRW/SRU diagnostics.
992 Fixed SEGV in yaz-client that occured for HTTP connection errors.
996 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
997 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1000 CQL changes to reflect recent changes to the specification:
1001 * Documentation talks about context sets instead of index sets.
1002 * Documentation talks about indexes instead of qualifiers.
1003 * The CQL-to-PQF transformer's configuration file now uses
1004 "index.set.name = <attributes>" instead of the old form
1005 "qualifier.set.name = <attributes>". (Both forms are still
1006 understood but the latter is deprecated.)
1007 * CQL terms with no explicit index specified are now interpreted as
1008 cql.serverChoice instead of srw.serverChoice (which of course
1009 behaves exactly the same.)
1011 --- 2.0.7 2003/12/16
1013 MARC conversion can now generate ISO2709 output in another
1014 character set. yaz-marcdump uses this facility if you invoke it
1017 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1018 functions from there can be used from C++.
1020 --- 2.0.6 2003/12/04
1022 Frontend server now transfers memory from decoded packages to stream
1025 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1026 references to show up.
1028 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1029 the ZOOM Abstract API. The older names for the same options are still
1030 also supported for the benefit of old applications.
1032 ZOOM-C supports "implementationId" and "implementationVersion" options
1033 to go along with "implementationName". These allow the user code to
1034 specify identification strings to be sent to servers.
1035 Add OID for the new ExtLite attribute set.
1037 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1038 as requested/supplid by Ere Maijala <ere@atp.fi>
1040 For generic frontend server, reverse the order of
1041 "toolkit-supplied / application-supplied" strings sent as implementationId,
1042 Name and Version. Also, remove the spaces around the slash. This brings
1043 the GFS in line with the behaviour of ZOOM-C on the client side.
1045 Add function ZOOM_scanset_display_term.
1047 yaz-client shows scan displayTerm if present.
1049 Utility yaz-iconv is now installed by default along with the man page
1052 Extend configure check for OpenSSL to use pkg-config where available (such
1055 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1056 server to specify uid/gid/mask for socket using the format
1057 unix:[user=uid,][group=gid,][umask=mask,]file=path
1058 If file= is omitted the existing format is assumed, e.g.
1060 in which case the mask is 0666 (rw for everybody).
1062 Major restructure of YAZ source. All source in libyaz is in src directory.
1063 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1064 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1066 Added man page for utility yaz-marcdump (used to be called marcdump).
1067 yaz-marcdump is installed by 'make install'.
1069 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1070 of incoming package failed.
1072 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1074 Change prototype of odr_perror: add const to message string.
1076 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1078 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1079 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1080 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1081 DNS lookup. There should not be any compatibility problems with this
1082 assuming that blocking=1 or 0 is used.
1084 Fix bad reference in UNIX comstack in function cs_addrstr.
1086 Fix for compilation on AIX.
1088 The generic front-end server (server/seshigh.c) now supports returning
1089 Init diagnostics to the client in User-information-field, in
1090 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1093 --- 2.0.4 2003/09/04
1095 Allow any CQL relation (not just all,any,exact,scr).
1097 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1098 that features the same UI.
1100 Implemented command update0 in YAZ client which is equivalent to
1101 update but uses old of Ext Update ASN.1.
1103 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1104 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1105 Previously no OID was used for this info.
1107 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1108 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1109 returns 'malformed search term' otherwise.
1111 SortResponse member resultCount now set to NULL in sort handler of
1114 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1117 Add three new utility functions for translating OIDs between various
1118 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1119 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1120 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1121 char *oid_to_dotstring(const int *oid, char *oidbuf);
1122 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1124 Reverted modifications for ES Update definition for z_IU0Update
1125 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1126 is back to YAZ 2.0.2.
1128 String value attributes for CCL parser.
1130 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1131 which their FirstSearch server returns in Init responses, sometimes
1132 carrying useful diagnostic information when Init fails. This has the
1133 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1134 "z39.50/oclcui.asn", where its definition is somewhat different from
1135 what OCLC document on their web-site, as required to interoperate with
1138 Support for anonymous authentication in yaz-client. Use the command
1141 * Fix the OID of the Index Data-local "admin" Extended Service from
1142 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1143 the 1000, which indicates a locally-defined OID, was a mistake.
1145 --- 2.0.3 2003/06/20
1147 Fix CCL directive @case handling so that it affects string match for
1148 both CCL keywords and qualifiers.
1150 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1151 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1152 Decoder has been updated with ASN.1 changes as listed in
1153 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1154 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1155 z_IUUpdate, remains unchanged.
1157 ZOOM_record_get may now return a record in a specific character set.
1158 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1159 "from" is the character set of record as returned by target. "to" is
1160 the character set to be returned. If omitted, "to" is UTF-8.
1162 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1164 New ODR utility, odr_getelement, which returns name of element for
1165 which encoding/decoding failed.
1167 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1168 in cases where a required element was omitted.
1170 Bug fix: some MARC8 sequences were not converted.
1172 New ZOOM option "step" which specifies number of records to be
1173 retrieved in one chunk. Used in conjunction with "start" and "count".
1175 SRW support for yaz-client. Use scheme http: to use it, e.g.
1178 yaz-client no longer does (un)intelligent character set conversions
1179 by default. Can be enabled with charset and marc_charset commands.
1181 xmalloc trace fix for 64-bit systems such as DEC alpha.
1183 Solaris 2.6 compile fix.
1185 New function, cql_strerror() translates SRW error codes, as returned
1186 by cql_transform_error(), into human-readable English strings. Used
1187 in yaz-client diagnostics when appropriate.
1189 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1190 converts it into a type-1 query which is sent to the server. This
1191 makes CQL available for use with all Z-servers, as opposed to the tiny
1192 minority that can handle CQL queries themselves.
1194 --- 2.0.2 2003/04/28
1196 New Debian package layout similar to the Redhat Package layout.
1198 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1199 and search result respectively.
1201 --- 2.0.1 2003/04/25
1203 Redhat package is now several packages: libyaz (runtime libraries),
1204 libyaz-devel (development and documentation, and yaz (utility programs).
1205 Package spec file by Morten Bøgeskov.
1207 New member 'schema' in struct bend_fetch_rr which the name of requested
1208 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1209 handler MAY set this to reflect the schema of the returned record.
1211 New member 'display_term' in struct scan_entry. GFS now sets member entries
1212 and allocates scan entries to be filled by user scan handler. In previous
1213 version, entries member was allocated by the scan handler. That still works,
1214 but the GFS will ignore member display_term - assuming it was NOT set by
1215 the handler. The fact that the GFS now allocates the entries both allows
1216 for new members and makes a scan handler easier to write.
1218 Fix CQL lex buffer overflow.
1220 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1221 SRU default recordPacking is string.
1223 SRU protocol support for frontend server.
1225 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1227 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1229 Added scan for the ZOOM shell (zoomsh).
1233 * String Identifers for Schemas (Amendment 5).
1234 http://lcweb.loc.gov/z3950/agency/amend/am5.html

1249 Support for SRW 1.0 over HTTP. This is an optional feature and
1250 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1253 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1254 on the same port. SRW SearchRetrieveRequests are mapped
1255 to bend_init,bend_search,bend_fetch,bend_close.
1257 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1259 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1260 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1262 ZOOM connections are SRW based if schem http is used for hostname
1263 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1264 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1266 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1267 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1268 distance=n, order=true/false, relation=le, prox unit=word. If
1269 n is omitted, distance 1 is used.
1271 Fixed problem with C compiler include path in wrong order.
1273 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1274 on Solaris. Patch from Ko van der Sloot.
1276 New MARC decode API. All new functions operate on a yaz_marc_t
1277 handle. The most important new functions are: yaz_marc_create,
1278 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1279 decode and destroy respectively. Decoder can produce formats
1280 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1281 include/yaz/marcdisp.h.
1283 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1284 to UTF-8, UCS-32, wchar_t or Latin-1.
1286 * Prototypes for yaz_iconv_-functions moved to separate header
1287 include/yaz/yaz-iconv.h.
1289 Make a few private functions 'static' in unix.c. This prevents
1290 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1292 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1293 are set when Init Response is received.
1295 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1296 but returns diagnostic set as well.
1298 New function yaz_strerror which is a portable wrapper for
1299 strerror/strerror_r/GetLastMessage.
1301 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1302 is returned for MARC. If type is "oai", then OAI MARC is returned.
1304 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1307 --- 1.9.2 2002/11/26
1309 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1311 Fix bad race conditions on SIGTERM and terminate gracefully in
1314 Move retrieval (data1) module to Zebra since nobody seems to be
1317 Add GRS-1 render for ZOOM using same format as yaz-client.
1319 --- 1.9.1 2002/10/05
1321 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1323 Fix broken ESpec handling in data1 module.
1325 SGML reader parses comments and makes them part of the data1 tree.
1327 Added several type casts so that YAZ compiles as C++ code.
1329 ZOOM didn't handle PDU encoding failures properly.
1331 Added more Bib-1 diagnostics (approved extensions).
1333 GNU configure: better check for iconv.
1335 More portable use of accept, getpeername. Check for socklen_t. Use
1336 int/size_t if socklen_t is not defined.
1340 PQF parser rejects bad queries - including those with extra
1341 characters in them. PQF parser used to silently ignore that.
1342 Cleaner API for PQF added, which allows you to get detailed
1343 error information for bad queries (see yaz/pquery.h).
1345 Fixed bug in ZOOM_record_get for type "database".
1347 Implemented mini iconv library supporting conversions between
1348 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1350 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1352 --- 1.8.9 2002/08/20
1354 Fixed ZOOM C record cache so that preferredRecordSyntax and
1355 elementSetName is used to check for already fetched records.
1357 --- 1.8.8 2002/08/02
1359 Added three members in bend_initrequest structure to facilitate
1360 character set negotiation.
1362 Fixed a bug in frontend server that could cause indefinite
1363 loops under rare conditions.
1365 Revised character set utilities (charneg.h) so that encoding
1366 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1368 For PQF, directive @term <type> sets term type for Scan/Search.
1369 Here <type> is general, string, numeric, null. The term type
1370 is inherited - just like @attr.
1372 New call odr_set_charset that sets character set conversion for
1373 international-strings on a ODR stream. Prototype is:
1374 int odr_set_charset(ODR o, const char *to, const char *from);
1375 The InternationalString is still represented as C string in YAZ
1376 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1377 won't). On the protocol level, you can use any encoding.
1379 Support for UNIX sockets in ZOOM.
1381 Solaris recv sometimes returns errno == ENOENT. It is treated as
1382 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1384 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1385 both client and server. Code by Morten Bøgeskov.
1387 --- 1.8.7 2002/05/22
1389 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1390 that they can be used directly from Visual Basic. You must recompile
1391 your windows APP if you're using ZOOM.
1393 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1394 Commands "lang" and "charset" sets language and character set respectively.
1395 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1396 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1398 Attributes from multiple CCL fields may be OR'ed rather than merged
1399 using directive "@field or". Fields are still merged by default -
1400 equivalent to "@field merge".
1402 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1405 Fixed bug in zget for parameter ExtendedServicesResponse.
1409 --- 1.8.6 2002/03/25
1411 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1413 Client displays USR.1:SearchResult-1 (hits per term).
1415 Additional Search Info for search in Generic Frontend Server.
1417 Fixed CCL parsing of "field=s".
1419 WIN32 installer - using the excellent NSIS software from nullsoft.
1421 Fixed CCL parsing of "field = - <number>".
1423 Added function yaz_marc_decode that decodes MARC for line mode
1424 display or XML (similar to that used by JZKit).
1426 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1427 Z39.50. But ISO/ILL was, however.
1429 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1430 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1432 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1433 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1435 --- 1.8.5 2002/02/03
1437 New YAZ client features: Command completion and new commands:
1438 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1439 Code provided by Jacob Poulsen.
1441 New call oid_trav, that visits all registered OIDs via callback.
1443 Function ZOOM_record_get now returns const char pointer rather than
1444 void pointer. It saves a lot of type casts.
1446 For YAZ client, command "auth" now allows you to set authentication
1447 in IdPass style. It is enabled when three tokens are given - order
1448 is user, group and password.
1450 Fix memory leaks in MARC record handling for ZOOM.
1452 New option for YAZ client, -k <kilobytes> that sets
1453 maximum record size. Similar to -k option for generic frontend
1454 server and yaz-ztest.
1456 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1458 Prefix query parser reports "fail" when bad attribute set is given.
1460 Fix in MARC decoder. Proximity logging. Fix for attribute set
1461 in scan handler for server. Patches by Shigeru Ishida.
1463 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1466 Configure option --with-openssl=<dir> now works when a directory is
1467 specified. Patch provided by Morten Bøgeskov.
1469 New option for YAZ client, -u <auth>, that sets authentication.
1471 ZOOM fix: error information was sometimes "missing", since error
1472 was cleared/reset too when it shouldn't.
1474 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1476 --- 1.8.4 2002/01/04
1478 Scan for ZOOM API. New object ZOOM_scanset. New functions
1479 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1480 ZOOM_scanset_destroy.
1482 New ZOOM function, ZOOM_connection_last_event, that returns type
1483 of last event (such as "receive data", "send data", "apdu received",
1486 New ZOOM option, schema, that specifies schema for retrieval.
1488 New CCL feature. Qualifiers can be aliases for one or more
1489 other qualifiers (if more than one is given, OR is used).
1491 ZOOM uses named result sets if target supports it.
1493 Two new YAZ client commands: . (dot, which sources a script of YAZ
1494 client commands), and ! (to execute shell command.). Implemented
1497 Working on Debian packages.
1499 --- 1.8.3 2001/11/19
1501 YAZ client enables named result sets only if target supports it.
1503 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1505 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1506 with key="host" to get same result.
1508 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1509 Function Z3950_resultset_record(s) returns references to records
1510 "owned" by resultset. To become owner use Z3950_record_clone.
1512 Function z_ext_record handles Extended Services. Thanks to
1515 --- 1.8.2 2001/11/12
1517 CCL Parser fix: ignore token comma when dealing with and-lists.
1519 Documentation updates for COMSTACK.
1521 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1522 Changed prototype Z3950_records. For some functions, int parameters
1523 were changed to size_t.
1525 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1528 New MARC decode/display function, marc_display_exl, which properly rejects
1529 non-ISO2709 records. YAZ client uses it.
1531 --- 1.8.1 2001/10/29
1533 Fix bug: local attribute set wasn't set correctly in PQF strings.
1537 * Old Z39.50 codecs no longer supported.
1539 Added ZOOM C binding. See http://zoom.z3950.org/
1541 Renamed states for COMSTACKs to avoid confusion with events.
1543 Implemented cs_look and proper cs_rcvconnect.
1545 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1547 Configure detects POSIX threads on OpenBSD.
1549 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1550 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1552 When error is returned from present handler, non-surrogate diagnostic
1553 is returned in present response (and fetch handler is no longer called).
1555 * Minor adjustments to pquery parser (PQF). Token characters may be
1556 escaped by using backslash (C-style).
1558 PQF parser allows string attribute values to be specified. For @attr,
1559 non-numeric characters after the equal-sign are treated as strings
1560 (e.g. @attr 9=title).
1562 CCL trunction character may be defined (@truncation in file)
1564 * function zget_ExtendedServicesRequest sets waitAction to
1565 waitIfPossible (was wait).
1567 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1570 CCL operator names may be set in field definition files (CCL_bibset).
1571 See ccl/bib1 for an example.
1573 Fixes in ASN.1 compiler for C++ compatibility.
1575 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1576 and "op_or" to avoid conflict with C++.
1578 Fixed problem with GNU readline detection on Redhat 7.0.
1580 Added step-size for Scan backend handler.
1582 Fixed bug that made the frontend server crash when no attribute
1583 set was specified for scan.
1585 Front-end server automatically switches to original working directory
1586 when installed as an NT service. Previously -w had to be specified to
1589 Added extended attributes for retrieval module (data1), so that data1
1590 records carry d1_readXML/SGML attributes. d1_read also supports
1591 null-data rules ( <tag/>)
1593 On UNIX when POSIX threads are available, a separate library libyazthread
1594 is created. Programmers should link with that library and the yaz library
1595 when using threads. The reason for the split was that some applications
1596 on Linux, such as Apache, doesn't work well when using shared objects that
1599 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1600 (or any frontend server) in SSL mode by specifying ssl: followed by
1601 address. Only tested on UNIX.
1603 Added feature for CCL module. Virtual structure s=al or s=ol generates
1604 and-list and or-list respectively instead of phrase search.
1608 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1609 log_mask_str. This was done to avoid name conflicts with other libraries
1610 (such as other PHP extensions).
1612 Added raw OID member for preferred record syntax (request_format_raw)
1613 and returned record syntax (output_format_raw) for backend fetch method.
1615 Config file yaz-config now accepts options so that it returns specific
1616 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1618 Shared library support for UNIX using GNU libtool.
1620 * Modified backend interface. Request/Response struct's replaced by
1621 one read/write C struct. For example bend_fetchrequest and
1622 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1623 Every handler - even search has to be registered in bend_init
1624 handler. This means that the YAZ library no longer refers to
1625 external functions and it makes it possible to make the whole
1626 thing a single DLL/SO.
1628 Added Segment handler for backend server.
1630 Added Zmbol/Zebra administrative functions to YAZ client.
1632 Threaded frontend server on UNIX (when POSIX Threads are available).
1633 Starting the server with option -T enables multi-threading.
1637 Added configure option --enable-comp/disable-comp to control use
1638 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1639 located in sub directory asn.
1641 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1642 in ${exec_prefix}/bin along with the other programs yaz-client and
1645 GNU automake used to maintain makefiles.
1647 Added several OID's.
1649 Changed retrieval module so that we can load records with no abstract
1650 syntax defined. Tagpaths in these records are fully composed of string
1653 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1657 On UNIX, the generated makefile now supports a proper 'make install'.
1658 The prefix can be set via GNU configure to set the install location
1659 (default is /usr/local).
1661 * YAZ programs client and ztest were renamed to yaz-client and
1662 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1663 locations, such as /usr/bin,/usr/local/bin,etc.
1665 * YAZ Header files were moved from include to include/yaz. YAZ Header
1666 files are referred to as include <yaz/log.h> rather than <log.h>.
1667 The YAZ include path (-I ..) is therefore the same as before. Programmers
1668 should update their #include statements or use -Ipath/include/yaz
1669 instead. The main motivation for doing this change is that YAZ header files
1670 can be installed in "standard" locations /usr/include,/usr/local/include
1671 without introducing conflicts, since ALL YAZ header files are stored
1672 in subdirectory yaz (under /usr/include for example).
1674 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1675 rather than project/workspace files. We switched because project files
1676 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1679 Changed name of logging function, logf, to yaz_log, to prevent name
1680 clash with some math-log functions. The YAZ header log.h defines logf
1681 to yaz_log (#define) so there should be no incompatibilities by this
1684 Added bend_start/bend_stop handlers for server. These handler are
1685 called on start/stop of server. For windows they are called whenever
1686 a service is started/stopped.
1688 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1689 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1690 in util/yc.tcl. The auto-generated C code structures are, in a few
1691 cases, incompatible with the old decoders. There are differences in the
1692 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1693 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1694 The preprocessor variable ASN_COMPILED is defined when the compiled
1695 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1696 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1697 wish to use the old encoders/decoders you can specify --disable-yc
1700 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1701 version so that it supports both new - and old version of DB Update
1703 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1704 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1705 change. The name parameter can be set to 0 in which no name is specified
1706 for the construction. The macros odr_implicit and odr_explicit sets name
1707 parameter to zero for the construction involved. New macros
1708 odr_implicit_tag and odr_explicit_tag are similar to the others,
1709 except that a name parameter is added. For programmers' that don't use
1710 ODR they probably only need to change the call to z_APDU and z_External.
1712 Added access control facility by interfacing the TCP wrapper library.
1713 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1714 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1715 name of the daemon and enables the access control as specified in
1716 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1718 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1719 den Dool <H.M.vdnDool@kub.nl>.
1721 Added reference ID parameter to most functions in server API - refer
1722 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1724 Changed name of ccl library to libccl.a (was ccl.a).
1726 Fixed bug in decoder for Explain (Category TargetInfo).
1728 Added support for GNU readline in client. Thanks to Jacob Poulsen
1729 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1731 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1732 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1733 IMPLEMENTATION! This change was made to the development version before
1734 the ZIG decided to retract the amendment. If any users MUST be
1735 compatible with the original Update definition, PLEASE CONTACT US, and
1736 we will include a separate definition corresponding to the old Update
1737 ES. Note that because of the change to the ASN.1 of the
1738 TaskPackageRecordStructure we cannot define a single structure that
1739 will support both versions.
1741 * Added const modifier to buffer parameter for some ODR/BER encoding
1742 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1743 completeWAIS, odr_dumpBER.
1745 Fixed bug in client.c which caused a crash when a scanResponse didn't
1746 contain positionOfTerm.
1748 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1749 * will cause an error in a client if a non-YAZ target sends both a
1750 * list of Scan entries and non-surrogate diagnostics.
1752 Retrieval module enhancements. Tag sets may be typed in the reference
1753 to it. From the .abs-file the "tagset" directive takes a third optional
1754 integer type for the tag set referenced. From a .tag-file the "include"
1755 directive takes a third optional type as well. The old "type" directive
1756 in the tag set itself is still recognized but acts as the default type
1759 Backend interface change. Individual Scan terms returned from bend_scan
1760 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1761 in include/backend.h.
1763 Retrieval module enhancements. Multiple tag sets and attribute sets may
1764 be specified in abstract syntax specs. Revised the error/warning for
1765 logging messages reported by the retrieval module when reading the
1768 Object Identifier system (oid_..) changed. The API is backwards
1769 compatible but the oid-routines now allocates new OID's when needed.
1770 Raw OID's may be specified in oid_getvalbyname.
1772 YAZ now uses GNU configure to generate Makefile(s).
1774 * Minor changes in some of the member names of DeleteResultSetRequest and
1775 DeleteResultSetResponse. See include/proto.h.
1777 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1778 and added member 'languages' in TargetInfo (which was missing).
1780 Changed the way attribute sets are handled in the retrieval
1781 module. These are now cached, just like the abstract syntaxes
1784 Changed YAZ so that it links with compiled ASN.1.
1786 Added Explain-schema definitions and mapping routines. The following
1787 Explain categories have been implemented: AttributeDetails,
1788 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1790 Fixed minor bug in Windows version of Server Library.
1792 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1794 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1796 Added EXTERNAL: UNIverse Resource Report (non-standard).
1798 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1799 ENUMERATED and SET OF.
1801 * Added 'const' to some of the char pointer arguments for the
1802 functions, data1_read_node, data1_getelementbytagname,
1803 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1806 Fixed bug in data1_insert_taggeddata - the last_child member of
1807 parent wasn't initialised.
1809 * Changed data1_read_record and data1_read_node so that the supplied
1810 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1811 doesn't refer to any parts of the "SGML"-buffer.
1813 Fixed bug in server library (Windows version of statserv_remove).
1815 * Changed code so that it compiles as C++. The type definition
1816 of Odr_fun which is a member of Odr_arm was changed. The result is,
1817 that an explicit typecast is needed for the fun pointer when
1818 using Odr_arm - as in:
1819 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1821 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1823 Implemented the new structured date and time definition as approved
1824 by the ZIG. Added schemaId element to the specificTag in Espec-1
1825 (also approved at the last ZIG). Thanks to RVDM.
1827 Added some Object identifiers (RVDM).
1829 Changed the Update Extended Service (RVDM).
1831 Added command "refid" to client which specifies referenceId for
1832 the following requests.
1834 Implemented extended service handling for server. See ztest.c
1835 for an example as well as backend.h. New handlers are registerd
1836 in the Init handler.
1838 * Changed interface for sort in server.
1840 Added new members to statserv_options_block. It allows a server
1841 to read options from another source than just the command line. Thanks
1842 to Charles Woodfield.
1844 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1845 renamed to zboolean. Some C++ compilers complained about the name.
1847 Minor changes to gils.abs. Added index 's' (sort) on title
1848 and date/time-last-modified.
1850 --- 1.4pl2 1998/1/30
1852 Fixed bug in server library regarding inetd mode (-i). This bug
1853 was introduced by release 1.4.
1855 --- 1.4pl1 1998/1/29
1857 Added sort facility in client and backend server interface.
1859 Fixed problem with dependencies in Makefile(s).
1861 Fixed bugs for encoders/decoders of extended services and
1864 Implemented sub-tree feature for schemas. Sub-trees are
1865 referenced in *.abs-files. See explain.abs for an example
1866 of the use of this feature.
1868 Modified bib1.att; local attributes for ANY didn't include
1869 ANY itself (only affects use of the retrieval module).
1871 Fixed bug in plain SGML reader in function data1_read_node:
1872 tags with prefix "var" was incorrectly interpreted as variants.
1874 Added feature "sub-schemas" to enable references to - and definitions
1875 of - group of elements.
1877 * Removed member parent from type data1_element (in data1.h).
1879 Implemented function odr_nullval() that returns the value of
1882 * Removed member num_children from data1_node (in data1.h).
1884 Made NT service interface part of the server library. The
1885 function statserv_main uses the NT service when required and
1886 calls the statserv_start / statserv_close routines.
1888 Routine zget_SearchRequest and zget_PresentRequest fills
1889 resultSetName/Id member with "default" instead of "Default".
1891 Fixed memory leak in server. Request queue member wasn't freed.
1893 Fixed nmem_exit so that memory is freed.
1897 Revised the CCL parser utility to be thread safe.
1899 Added function, oid_ent_to_oid, to replace the function
1900 oid_getoidbyent, which is not thread safe.
1902 * Added nmem_init and nmem_exit to initialize and release
1903 NMEM resources. Function nmem_init should be called once in the
1904 initial thread before NMEM/ODR is used. statserv.c and client.c
1905 have been changed accordingly. The change was necessary to make
1906 NMEM thread safe. The NMEM memory pool is shared amongst threads
1907 in a process. Unix-based applications will still work fine without
1910 Added NT Services interface for the the Z39.50 (statserv) Server.
1911 Refer to the ztest.c source on the usage.
1913 Windows 95/NT port using MSVC5.0. Project files are included in the
1916 * Defined new 'global' handle for the retrieval (data1) system. The
1917 new handled, data1_handle, describes the state of the data1 system.
1918 This handle is passed as first argument to virtually all
1919 data1 related routines. The functions data1_create and data1_destroy
1920 creates and destroys a data1 handle respectively.
1922 Added ODR encode stream member to all backend request structures
1923 init, search, scan etc. This stream should be used to allocate all
1924 memory used for the response when thread safe operation is needed.
1926 Changed the comstack utility, cs_addstr, to be thread safe. The
1927 returned hostname string returned by the function is now part the
1930 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1931 function. The cs_straddr takes a COMSTACK handle as argument, so this
1932 function must be used after cs_create and before bind/connect.
1933 This function is thread safe.
1935 Moved test server to 'ztest' directory - generic server code still
1936 in 'server' directory.
1938 Made prefix query (pquery.c) utility thread safe.
1940 Added new function modifier YAZ_EXPORT to 'export' public DLL
1941 functions when using windows (see include/yconfig.h).
1943 Added definitions to the OID database (util/oid.c) (RVDM).
1945 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1947 Added call to ccl_rpn_delete in client program.
1949 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1950 release of RPN structure.
1952 Added support for C++, headers uses extern "C" for public definitions.
1953 With input from RVDM.
1955 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1956 Thanks to Ronald van der Meer (RVDM).
1958 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1960 Added support for private extensions to the OID database
1961 (oid_setprivateoids()). Thanks to RVDM.
1963 Added optional, physical ANY (key replication)
1965 Fixed null-reference problem in GRS-1 output filter.
1967 Proximity operator added to Prefix Query Format (PQF).
1969 In test client command "base" accepts multiple databases.
1971 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1975 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1977 Smallish bug-fixes in the new encoders/decoders (explain).
1979 Bug fixed in DeleteRequest.
1981 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1983 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1985 Added SOIF syntax (using private OID for now) to retrieval module and client.
1987 Added Update extended service.
1989 Added SearchResult-1 additional info structure.
1991 Added optional CCL (ISO8777) interpreter as separate module. Available
1994 --- 1.2 1996/6/10 (1st anniversary release)
1996 Added Summary record syntax. Lightly tested.
1998 Added OPAC record syntax. Untested.
2000 Added ResourceReport service encoders/decoders. Untested.
2002 Fixed bug in z_Unit - wrong tagging on unitSystem.
2004 Fixed bug in the DiagRecs decoder.
2006 Added options for max PDU size and session timeout to frontend-server.
2008 Added documentation of query-language parsers and other supporting utilities.
2010 [frontend-server] Added Attribute set to the bend_scanrequest API.
2012 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2013 surrogate diagnostics were generated.
2015 [retrieval] Allow multiple local values for attribute.
2017 [retrieval] Allow multiple attributes per element in .abs files. index type.
2019 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2021 --- 1.1pl2 1996/4/10
2023 Minor changes, mostly specific to Zebra's requirements (retrieval)
2027 Repaired bug in frontend server when running multiple listening
2028 endpoints in dynamic mode.
2030 z_External() now won't break if a known, ASN.1 value comes encapsulated
2031 in an octet-string. The value will pass through unmodified in an Odr_oct.
2033 Added a bit of code to the demo client to decode & display
2034 ASN.1-structured records represented in the octet-aligned branch of
2035 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2037 Added z_ext_getentbyref() to the ASN module. Doc updated.
2039 * Completed the SCAN definition in the ASN module. This may break SCAN
2040 code based on older YAZ-versions at compile-time. The fix is easy -
2043 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2044 under the SCAN definition. Remember to initialize this, server-people.
2046 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2047 that this does not extend to ODR and ASN.
2049 Comstack allows insertion of established socket (primarily for
2050 inetd-operation of servers). Doc updated.
2052 Front-end server can now start from the inetd in TCP mode. Doc
2055 --- 1.0pl4 1996/1/24
2059 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2060 the rank and record number.
2062 Adjustments to the frontend server.
2064 Fixed diagnostic BER dumper. It ignored the file argument.
2068 Various changes to retrieval module.
2070 Changed the union discriminators of the protocol files from enums to
2071 ints paired with #defines.
2073 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2076 *Changed operator in the RPN structure to 'roperator', again to avoid a
2079 Fixed problems in Explain decoders/encoders.
2081 --- 1.0pl2 1995/12/6
2083 Memory bug in log module fixed.
2085 --- 1.0pl1 1995/12/5
2087 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2089 Bug in Explain DatabaseInfo module fixed.
2091 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2095 The shift to v1.0 signals that we now consider the *core* functionality
2096 of YAZ reasonably stable (the core being more or less equivalent to
2097 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2098 tested (Explain not at all - though that will happen soonish).
2100 Minor changes to code to support Windows port.
2102 Various minor changes after we're getting to use GRS-1 & co. more.
2104 Added Espec-1 format.
2106 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2107 of the protocol and it cannot be selected when encoding (maps into 'string'
2108 when decoding). Needed to talk to some servers.
2110 Demo client can request simple element set names.
2112 Added Diagnostic Format encoders/decoders.
2114 Added simple Close handling to frontend server (no hooks for resource
2115 reporting yet), and demonstration client.
2117 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2119 --- 1.0b3 1995/08/24
2121 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2122 handled incorrectly when records were requested in the searchResponse. This
2123 will only affect you if you use the frontend-server.
2125 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2126 Test-client will ask for and print GRS1. Ztest will return dummy records
2129 Added Explain encoders/decoders to the service-level API. Untested.
2131 Added Extended Services: Item Order encoders and decoders to the Service-
2132 level API. Untested. We could use a recent copy of the pertinent bits
2133 of the ILL protocol to add those bits.
2135 Added diagnostic format 1 encoders/decoders to the service-level API.
2138 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2139 odr_cons.c, which causes a more correct output.
2141 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2142 was always set to 0 when no records were requested in the searchRequest.
2144 * Added better external-handling. This shouldn't harm old code that
2145 *encodes* externals. It can break code that looks for a
2146 'single-ASN1-type' representation, since those types that are known
2147 are now decoded immediately. Look at the SUTRS sample code in
2148 seshigh.c and client.c. Documentation updated.
2150 Handling of structured records in bend_fetchresponse. Length -1 marks
2151 structured record, type is deduced from format field.
2153 --- 1.0b2 1995/06/27
2154 Fairly quick maintenance release to add SUTRS support.
2156 Fixed handling of SUTRS records in the demonstration client.
2158 * Added format field to the bend_fetchrequest and bend_fetchresponce
2159 structures of the backend API (frontend server). When the record is
2160 returned, the value of the format field is mapped to an OID. The
2161 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2162 of the record. The special value VAL_NONE in the bend_request means
2163 that no specific format was requested by the client. Documentation
2164 updated accordingly. Test server (ztest) will return a fixed dummy
2165 SUTRS record if your client requests SUTRS.
2167 Documentation updated accordingly.
2169 You can now set external libraries and RANLIB support in the top-level
2173 First public release.
