1 Added yaz-client command querycharset which specifies character set for
2 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
3 (termListAndStartPoint).
5 Charset ISO5428:1984 is an alias for ISO5428-1984.
7 Implemented a way to perform scan in a result set using Z39.50. This
8 is achieved by attaching the result set name in the characterInfo
9 (type InternationalString) of OtherInformation in the Scan Request PDU.
10 The result set is identified in the otherinformation by the new OID:
11 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
12 This allows for scan in result set and faceted search . Zebra did some
13 of this in the APT term using attribute type 8 and value being result
14 set. Using the OtherInformation approach for this is cleaner and easier
15 to work with in proxies and the like. This facility can be used in
16 yaz-client using new command setscan which takes a result set as first
17 argument, start position (APT) as second.
19 Changed decoding of SRU XML packed records to deal with servers that
20 have recordData with XML data with multiple root nodes. Also make
21 comparison for recordPacking case insensitive. Again, one server
22 returns "XML" where others return "xml".
24 For SRU responses allow Content-Type application/xml as well as text/xml.
28 Fixed bug in character set conversion of BER strings. Bug introduced
33 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
35 For OID class, use oid_class consistently.
37 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
40 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
41 character set for bibliographic information interchange". By Giannis Kosmas.
43 Added documentation on new OID API.
47 Changes to generic frontend server interface: added new member
48 'query_charset' for bend_initrequest structure. A backend init handler
49 should set this member to its native character set for query terms.
50 When defined, the frontend server logic will announce this character set
51 to a client if the negotiationModel bit is set by the client. All server
52 implementors are encouraged to specify this. If a backend server does not
53 specify this a warning is issued using yaz_log(YLOG_WARN,..).
55 Added CCL utility to remove terms (stop words) from resulting RPN
56 tree. This is handled by functions with prefix ccl_stop_words_ .
58 New ZOOM C option, "rpnCharset", which allows client-side conversion of
61 Clean-up the CCL API. Moved some internal structures from ccl.h to
62 private header cclp.h. Changed ccl_parser_create so that a Bibset must
63 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
64 This is replaced by ccl_parser_find_str which takes a string instead.
66 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
67 libyaz.la is the core of YAZ except the generic frontend server and
68 does not depend on POSIX threads anymore. libyaz_server.la is the
69 generic frontend server facilities and uses POSIX thread functionality
70 if available. The libyaz.la no longer depends on POSIX threads because
71 the number of global structures is limited. NMEM no longer re-uses blocks
72 between threads ; it simply free's memory immediately but allocates in
73 "large" chunks as usual. We don't expect any performance penalties
74 because of this. The yaz_log system is still using a global log_level so
75 caution must be taken when modifying it with yaz_log_init_.. +
76 yaz_log_mask_str. This, however, should not cause any trouble because
77 these functions are called during initialization of application code
78 anyway. `yaz-config --libs server` returns libs for server applications;
79 `yaz-config --libs` returns libs for non-server applications.
81 New OID database - with public definitions in oid_db.h. Removed old OID
82 database including the head oid.h and definitions such as enum oid_value
83 and struct oident. The new OID database uses the same string names as
84 before but the 'protocol' is gone. There are now only two representations
85 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
86 converts from string to OID; functions with prefix yaz_oid_to_string
87 converts the other way.
89 Change to emit_term() in CQL-to-PQF query translation: when a term has
90 the /regexp relation modifier, do not process it for leading and
91 trailing "^" and "*", which have quite different meanings in regular
94 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
95 write handlers no longer carries a 'last' parameter. This will make
96 yaz_iconv flush "less" characters. A flush is performed by call to
97 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
99 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
100 removed, because function yaz_query_to_wrbuf does the same.
102 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
103 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
105 Deprecated MARC utility functions removed.
107 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
110 Branch split: YAZ_2_1_55_branch
112 --- 2.1.54 2007/03/16
114 Fix to ZOOM-C so that transparent reconnection is properly handled on
115 connections that are in asynchronous mode.
117 Fixed compilation on OpenBSD 4.0.
119 Large strings in GRS-1 records are now properly displayed in yaz-client.
121 Added character conversion support for "advancegreek"; based on patch from
124 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
125 sequence is met. Before the error was not set so it would be unknown.
127 Adjust yaz-marcdump MARC reader so that it skips until record separator
130 --- 2.1.52 2007/03/07
132 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
133 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
134 fd_set structure used as a bitmask for the FDs to be selected on.
136 Using ACX_PTHREAD macro to check for POSIX threads.
138 Fixed have-vsnprintf check.
140 --- 2.1.50 2007/02/23
142 Fixes for configure on BSD. Bug #900.
144 Added snprintf/vsnprintf wrappers for systems that don't have
145 limits (heavens forbid).
147 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
148 created before all previous tasks were completed and removed from the
149 task queue, the new task could be removed by a mistake.
151 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
153 Implemented pass-through CQL-to-PQF conversions. Bug #861.
155 Fixed bug #832: Problem with MARC/charset in yaz-client.
157 Fixed bug #668: save command line history for yaz-client.
159 Fixed bug #830: pkg-config support.
161 --- 2.1.48 2007/01/23
163 Extended ZOOM result set options with two options that may be read by
164 a client: resultSetStatus and presentStatus with values as specified for
166 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
168 Fixed bug #827: Using SSL fails on Debian etch.
170 Fixed bug #826: Weird looking chars for set of MARC records.
172 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
173 that is treated as an ItemOrder with itemRequest being an XML document
174 external. The value of "doc" is the content.
176 Extended the GFS search facility. New member of bend_search_rr
177 'estimated_hit_count' signals that hits is known to be an estmate
178 (higher or lower than real hit count). New member 'partial_resultset'
179 signals that the search was partial (hit count is lower or equal than
180 real hit count). For Z39.50, the information is stored in resultSetStatus
181 member of SearchResponse APDU. For SRU, the information is signalled
182 via SRU diagnostic 59: "Result set created with valid partial results
185 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
187 --- 2.1.46 2007/01/13
189 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
191 Added ZOOM_connection_peek_event.
193 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
194 the following new functions:
195 ZOOM_event_nonblock, ZOOM_connection_process,
196 ZOOM_connection_get_{socket,mask,timeout},
197 ZOOM_connection_fire_event_{timeout,socket}.
198 The existing blocking event handler, ZOOM_event, is a wrapper for the
199 + blocking ZOOM_event_sys_{poll,select}.
201 Implemented function ccl_xml_config which parses XML version of CCL
202 configuration (bug #798).
204 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
206 Added timings utility (yaz/timing.h)
208 --- 2.1.44 2007/01/03
210 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
213 Fixed bug #779: Rotation of apdu.log fails.
215 Fixed for character set conversions:
216 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
217 Honor G1 set in MARC-8 decoding.
219 --- 2.1.42 2006/12/17
221 Fixed bug #775: char conversion does not handle Alternative UTF-8
224 Implemented function yaz_marc_read_line which parses MARC line format
225 records. There is a wealth of formats out there. So far, this function
226 reads line records produced by yaz_marc_write_line.
228 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
229 more generic and easier to remember(!) options: -i format and -o format
230 which specifies input format and output format respectively - where
231 format is one of "marc", "marcxml", "line", "marcxchange".
233 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
234 does not print anything except warnings for records.
236 For yaz-marcdump, added support for MARC split into files (-s) with a given
239 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
240 spec, at http://www.loc.gov/standards/sru/record-update/
241 This has changed the binary layout of the following structs:
242 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
243 bend_update_rr . Patch by Ko van der Sloot.
245 Added GFS utility function bend_assoc_is_alive which returns 1 if
246 association is still alive (client is connected); 0 otherwise (client
247 closed connection). This allows busy servers to stop working for
250 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
251 been a separate piece of software. This version of ziffy has been modified
252 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
254 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
256 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
257 Client code may now interrogate options such as "init_opt_sort" to
258 find out whether the server claims to support various options.
260 --- 2.1.40 2006/11/27
262 Added utilities yaz_{set,get}_esn to set/get element set name from
265 Removed the build of libyazthread.la. The libyaz.so is the threaded version
266 of YAZ and has been so since YAZ 2.1.10.
268 Implemented ZOOM_record_error which returns error information for
269 record (surrogate diagnostic).
271 --- 2.1.38 2006/10/31
273 Updates for SRU Update by Ko van der Sloot:
274 1. Changed name from "operation" to "action"
275 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
276 versions in the code, marked as 'backward compatible'.
277 3. Added diagnostics for SRU Update.
279 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
281 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
283 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
285 For GFS, fixed problem with SRU diagnostic 'First record position out of
286 range' being issued for 0 hits.
288 zoomtst10 part of Windows Build.
290 --- 2.1.36 2006/10/13
292 Implemented yaz_filepath_comp which splits a path into file path
293 components (required by Zebra 2.0.3+).
295 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
296 BSD inspired license until now so this should not have any real impact on
297 anybody. See http://www.opensource.org/licenses/bsd-license.php
299 Fixed bug #687: Missing log lines.
301 Fixed bug #678: CQL to PQF translation does not preserve double-quote
304 Fixed bug #689: SRU diagnostics to be added.
306 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
307 whether a connection is idle (no more work do do).
309 --- 2.1.34 2006/10/04
311 Change type of optval from long to int for invocation of setsockopt with
312 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
314 Added support for specifying the max log file size for the Generic
315 Frontend Server. The size is given with option -r.
317 --- 2.1.32 2006/09/21
319 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
321 --- 2.1.30 2006/09/17
323 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
326 Fixed bug in Generic Frontend Server that could cause a server to stop
327 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
329 For the generic frontend server, the maximum record size is used as maximum
330 size of incoming packages (SRU + Z39.50). The value until was previously
331 only used in Z39.50 Init negotiation and, later, in a session controlled
332 sizes of records returned. This is controlled using -k option. It can be
333 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
335 --- 2.1.28 2006/09/04
337 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
340 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
342 New option for yaz-marcdump -lpos=value which allows setting a portion
343 of MARC header to a certain value.
345 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
347 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
348 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
350 --- 2.1.26 2006/08/15
352 Fixed problem with SRU mode type (soap, get, post) for yaz-client
355 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
357 --- 2.1.24 2006/08/08
359 Fixed MARC ISO2709 encoding routines to deal with character set
362 Minor changes to GFS logging. Database included in search request log
365 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
366 cached/multiple records.
368 Shared libraries are built by default on Unix+configure.
370 Changed cql2pqf transformation to use a different evaluation order. The
371 new order is: always, relation, structure, position, truncation, index
372 and relationModifier. Old order was: always, relation, relationModifier,
373 structure, index, position, truncation. Note that the the latter ones
374 override former ones for identical attributes.. The new scheme means that
375 it is possible to override any existing attribute with a relationModifier.
376 And also that it is possible to override everything for the index rule
377 (except the ones listed in relationModifier). No order is perfect but this
378 one, we believe, covers more real cases.. The "always" should have been
379 called "default", since the attributes there can be overridden with all
382 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
383 compilation phase, but also for yaz-config --cflags output. This allows
384 us to have public headers with Libxml2 stuff in them . It should also,
385 eventually, make Libxml2 checks redundant in packages using YAZ, such
388 --- 2.1.22 2006/06/15
390 Changed SRU update structure bend_update_rr so that SRU diagnostics are
391 stored in uri, message and details.. Previously diagnostics were stored
392 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
393 compatibility.. but he's probably the only one affected, so.
395 Added support for CCL, compiled on the client side, in ZOOM-C. This
396 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
397 input; the resulting query objects can be used for for searching with
398 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
400 YAZ' configure searches for OpenSSL by default.
402 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
403 SL_CTX_use_certificate_file. See
404 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
405 for more info. Thanks to Ko van der Sloot.
407 --- 2.1.20 2006/06/02
409 Bug #600: SRU GET, POST support for yaz-client. Introduced
410 command 'sru' which selects method SOAP/GET/POST.
412 Allow missingValueAction to be specified for the sortspec string -
413 function yaz_sort_spec. By default, the missing value action is null.
414 Use ! to specify "abort". Use = followed by stringvalue to specify default
417 Ensured that Present-handler (if defined) is called in GFS before any call to
418 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
419 searchRetrieve requests.
421 Documentation for YAZ is now based on the Docbook XML/XSLT using
422 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
423 is no longer depending on jade/openjade or docbook-to-man scripts.
424 PDF is no longer part of the distribution - but can optionally be
425 made using DSSSL/jadetex or FOP.
427 Added retrieval handling support in Generic Frontend Server to support
428 conversion between MARC/XML as well as XSLTtransforms. See
429 etc/yazgfs.xml for an example.
431 Added Authentication support to Generic Frontend Server in SRU
432 mode. Authentication using HTTP Basic is supported, as is the use
433 of 'x-username' and 'x-password' parameters in the request itself.
435 Added support for a new character set MARC8s identical to MARC8 except
436 that it converts combined characters to single Unicode characters in the
437 Latin-1 range (when possible).
439 --- 2.1.18 2006/04/24
441 ASN.1 compiler 0.4: generates brief Doxygen file header for
442 generated .h/.c files.
444 Utility yaz_iconv now supports conversion to MARC-8.
446 New facilities for the MARC module. The reading - and writing of
447 content are separate methods for the yaz_marc_t handle. The following
448 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
449 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
450 format). Write functions have prefix yaz_marc_write_.. The existing
451 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
452 available. Removed support for OAI-MARC and simplexml (not the
453 simplexml from PHP5).
455 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
456 to be returned for this connection.
458 --- 2.1.16 2006/03/31
460 Allow multiple languages and charsets to be specified with
461 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
462 negcharset iso-8859-1,utf-8
464 Translation of proximity nodes from CQL into PQF now works.
466 Moved to automake 1.8, 1.9.
468 Added function yaz_log_set_handler which allows a log handler to be
469 installed. This handler will be called for all log messages. Output
470 to file is also produced; but that can be disabled by passing NULL
471 fname to yaz_log_init_file.
473 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
475 For SRW (including GFS), accept application/soap+xml as content-type
478 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
479 produces NO stylesheet reference even if a default stylesheet is specified
482 --- 2.1.14 2006/03/14
484 Updated Windows package to include yazd.dll + yazd.lib for the
485 Development component.
487 If the environment variable YAZ_LOG is set, then it is used as a
488 string indicating the default level of logging to use if not
489 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
490 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
491 used as before. So, for example, to omit warnings from YAZ logging,
494 cql_transform() now map structure and other attributes before indexes,
495 so that index-specific structures and other attributes can override
496 defaults. So now a combination of mapping specifications such as:
498 index.dc.date = 1=date-modified 4=5
499 does the right thing.
501 cql_transform() now also respects the "always" mapping specification,
502 which establishes an initial set of attributes to be used for all
503 terms except where overridden by more specific attributes associated
504 with the index, relation or modifier.
506 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
507 which mode to use; one of "post", "get" or "soap" (SRW, default).
509 Fixes for yaz_iconv routines: changed trie-based character set conversions
510 to use only non-negative values for bit fields due to Sun's C compiler not
511 supporting negative values.
513 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
514 sequences where not read correctly. Fix by Rustam Usmanov.
516 Updated win/makefile to use options, settings which makes things
517 compile with VS C 2005.
519 --- 2.1.12 2006/02/01
521 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
523 In ZOOM socket code, use select instead of poll on MacOSX.
525 ZOOM-C now support client-side compilation of CQL into RPN that is
526 sent to the server, enabling CQL to be used against all Z39.50
527 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
528 ZOOM_query object, and submit it using ZOOM_connection_search().
529 The CQL-to-RPN translation uses a configuration file, the name of
530 which must be specified in the Connection's "cqlfile" option.
532 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
533 function, which takes as its start-term parameter a ZOOM_query object
534 (which may have had either CQL or RPN set into it).
537 --- 2.1.10 2005/11/29
539 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
540 GFS to support this as well. Backend handler, bend_srw_update, does the
541 update work. Code contributed by Ko van der Sloot.
543 Allow retrieval of Search Result-1 information in ZOOM by the use of
544 options that are attached to a result set. ZOOM documentation updated
547 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
548 UTF-8 conversion. Patch by Raj Patel.
550 Added option -m to GFS to control formatting of timestamps in log file.
552 Added 'exit' as synonym for 'quit' in yaz-client
554 Added support for specifying SRW resultSetId + resultSetIdleTime in a
555 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
556 for the new members. Patch by Ko van der Sloot.
558 Added support for SRU POST. It is supported for content-type
559 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
561 Do not build the separate Multi-threaded (MT) library libyazthread.la.
562 Instead make the library libyaz.la multi-threaded. Threading as a whole
563 can still be disabled by configure option --disable-threads. Previosly,
564 with older GLIBCs there were problems with MT libs under Apache. This
565 has now been fixed a long time ago.
567 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
570 CQL module modified to be case insensitive for relations/indexes/operations.
572 Fixed bug in CQL transform code: incorrect value relationModifieder
575 Added 'show all' command for yaz-client which retrieves all results
578 Added new yaz-client, xmles, which takes a (private) OID and
579 a document to be sent as an extended service request.
581 Describe new yaz-client commands wait_response and set_auto_wait.
583 Increase TCP/IP listener backlog from 3 (which I am guessing was
584 copied from the SunOS manual entry way back when) so SOMAXCONN, so
585 that the socket will queue as many incoming connections as it's able
586 to handle ongoing connections. In other words, it will never now
587 refuse a connection that it would be able to handle merely because
588 it's not got around to accepting() enough of the pending connections
589 yet. This is the behaviour anyway under Linux, where the listen()
590 argument is ignored; but not under BSD and on systems such as
591 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
592 YAZ-based servers should now be uniform across operating systems in
595 yaz-marcdump uses 64-bit file access on some systems. This is enabled
596 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
597 This allows yaz-marcdump to read large MARC batches (>2 GB).
599 Modified all YAZ source files - except the source which is auto-generated
600 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
603 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
604 corresponding to the existing *_setl() function. These allow option
605 values containing arbitrary valuues.
607 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
608 ZOOM_resultset_sort() in new applications. Its behaviour is identical
609 except that it returns an indicator of whether or not the sort
610 criterion was accepted (0 for OK, -1 for invalid).
614 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
615 MARC output rather than returning "new" buffer.
617 yaz-client warns about unknown init options.
619 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
623 Added support for SRW sort in Generic Frontend Server. Patch
624 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
625 sortKeys - or NULL if none is provided.
627 Fixed bug #307: It was impossible to specify indefinite/no timeout
628 for ZOOM_event. Special timeout value -1 now means indefinite timeout
631 Added support for multiple languages and charsets to be specified in
632 ZOOM. Each charset/language is separated by a blank. If negotiation is
633 in effect in init-response, Option
634 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
635 Code based on patch by Vasiliy Osadchuk.
637 Fixed bug #306: infinite recursion that occurred when calling
638 yaz_log_level_init as the first call (before other log level or
641 Fixed bug in scan handling in front end server: if preferred-Position-In-
642 Response was non-present, a NULL pointer referece was performed.
646 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
647 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
648 now defined for all those error codes. So instead of putting 109 in
649 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
650 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
652 Modified the yaz-marcdump utility to skip garbage bytes between MARC
655 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
657 Program yaz-client now exits and produces an error message if multiple
658 Z39.50 servers are specified on the command line (none or one allowed
661 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
666 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
668 Fixed bug #272: Preserve spacing for CCL terms.
672 Added support for virtual hosts and multiple backend servers for
673 the YAZ frontend server. The configution is XML based and
674 support specificition of CQL to RPN mappings and explain information.
675 See section "Virtual Hosts" in the YAZ manual.
677 Extended OPAC display utility. OPAC display utility renders
678 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
679 to supplement yaz_marc_decode_wrbuf.
681 Fixed a bug in MARC decoder that could caused it to crash for some
682 invalid MARC records. More diagnostics and warnings where added in
683 XML output (warnings, etc are stored in comments).
685 --- 2.0.34 2005/02/08
687 Fixes for UNIX domain sockets. Bug #261.
689 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
691 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
692 Added yaz_marc_subfield_str which defines subfield lead string which is
693 used in YAZ_MARC_LINE format. Default string is blank+$. Added
694 yaz_marc_endline_str which defines end of fields string used in
695 YAZ_MARC_LINE format. Default string is newline.
697 Experimental support for MarcXChange. This format can be produced
698 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
699 http://www.bs.dk/standards/MarcXchange.xsd
701 Added yaz-client commands scansize that sets maximum number of
702 entries to be returned by scan.
704 --- 2.0.32 2005/01/11
706 Added support for SRW scan in yaz-client and Generic Frontend Server.
708 * Added whereInList member to SRW Scan Term.
710 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
712 Fixed NMEM system to return aligned blocks on the smallest boundaries
713 that are suitably aligned for all possible types on the particular
714 architecture YAZ is being built for.
716 --- 2.0.30 2005/01/04
718 Fixed numerious warnings that was issued with newer versions of GCC.
720 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
721 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
724 Make YAZ Generic Frontend Server slightly faster.
726 Enhance (and reduce) logging for Generic Frontend Server.
728 Revert YAZ log system so that it flushes every write operation
729 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
731 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
732 instead of LOG_, due to name clash with syslog(3). LOG_ are still
733 present. New applications should define YAZ_USE_NEW_LOG=1 - this
734 will effectively disable old definitions.
736 --- 2.0.28 2004/11/09
738 Added yaz_log_time_format which specifies log format using
741 Added yaz_log_module_level which returns mask for a module. Value
742 is non-zero mask a if module is enabled; zero if disabled.
744 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
745 in include/yaz/cql.h.
747 Fixed bug #176: Dont throw diagnostics on empty SRU args.
749 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
751 Fixed bug #172: RPM builds does not enable SSL.
753 Doxyfile.in part of dist. Doxyfile generated by configure.
755 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
756 are given and the corresponding component does not exist.
758 Extend CCL documentation in YAZ reference. Describe r=r.
760 --- 2.0.26 2004/10/01
762 Fixed MARC->MARCXML conversion to properly deal with
763 fields, subfields, indicators having non-ASCII characters.
765 Fixed MARC->MARCXML conversion so that ASCII control characters
766 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
769 Added YAZ GFS support for conversion from Z39.50 surrogate
770 diagnostics to SRW surrogate diagnostics.
772 Bug fix: YAZ GFS did not return schema in explainResponse.
774 --- 2.0.25 2004/09/30
776 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
777 now converts recordSchema to elementSetName as well as schema URI.
779 Fixed bug in COMSTACK that prevented HTTP request packages from being
782 --- 2.0.24 2004/09/29
784 Added CCL facility r=r "range" which is similar to r=o "ordered" but
785 does not require white-space before and after the dash in a range, e.g.
786 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
789 Fixed a few AC_TRY_LINK configure tests that did not operate properly
790 due to new GCC removing "redundant" code.
792 Added yaz-client commands scanpos and scanstep that sets preferred
793 position and step-size for scan.
795 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
797 Added CCL utility ccl_qual_buf which parses one or more CCL
798 spec lines in a buffer.
800 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
801 of name and value - ignoring empty lines and comments.
803 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
805 Added odr_get_element_path which returns current element path for an
806 ODR handle. This utility is useful in error handling or user-defined
809 Added ODR_PRINT utility odr_set_stream which is is a more generic
810 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
811 to a write function and pointer to close function. The close function - if
812 non-NULL - will be called during odr_destroy.
814 Fixed bug in CCL parser where truncation char was not removed from
815 right side when truncation=both was in effect.
817 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
820 --- 2.0.23 2004/08/11
822 Fix buffer overrun in CQL parser when dealing with proximity (%).
824 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
825 to UTF-8/UCS conversion is now only based on codetables.xml.
827 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
829 --- 2.0.22 2004/08/06
831 Add support for more "commit changes" in ZOOM (uses Extended Services).
833 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
836 Yet another small fix for configure of SSL.
838 --- 2.0.21 2004/05/14
840 Fix SSL libs for configure when --with-openssl=DIR is given.
842 --- 2.0.20 2004/05/10
844 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
846 SSL comstack now uses yaz.pem certificate file on server side
847 by default. Certificate filename can be configured by calling
848 comstack function cs_set_ssl_certificate_file before cs_bind is used.
850 Fix bug regarding multiple calls to ZOOM_connection_connect.
852 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
854 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
855 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
857 ZOOM now allows inspection of X509 peer certificate for verification.
858 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
860 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
861 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
862 as "modular" but it simplifies things.
864 Added cs_get_peer_certificate to that returns peer X509 PEM.
866 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
867 NULL if SSL is unavailable.
869 Documentation about MARC decoding tools.
871 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
873 --- 2.0.19 2004/03/30
875 Rename CHANGELOG to NEWS to follow GNU style packing.
877 Fix bug with missing initialization of member in init_diagnostics.
878 This bug affects threaded version of GFS server.
880 --- 2.0.18 2004/03/20
882 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
885 Ensure zlib.dll is packed with Windows install.
887 --- 2.0.17 2004/03/17
889 Fix encoding of xsd:string to use text instead of CDATA.
891 Fix endless loop in CQL parser with unbalanced ".
893 Use a more compact way to store MARC-8 conversion tables.
895 --- 2.0.16 2004/03/16 Debian only
897 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
900 Update CQL parser to use new CQL 1.1 modifiers for booleans and
905 --- 2.0.15 2004/03/01
907 Another fix for decoding of XML packed records.
909 --- 2.0.14 2004/02/25
911 Fixes for Chunked encoding. White space not ignored after length spec.
913 Update NS and use default NS for SRW diagnostic elements.
915 --- 2.0.13 2004/02/23
917 Implement ZOOM_resultset_cache_reset which resets record cache.
919 Implement ZOOM_resultset_sort which sorts a result set.
921 Implement chunked HTTP transfer.
923 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
925 --- 2.0.12 2004/02/16
927 Added member 'schema' to bend_explain_rr structure so that backend
928 can specify explain record identifier. Defaults to Zeerex 2.0.
930 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
932 --- 2.0.11 2004/02/16
934 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
937 Added init command for yaz-client which sends "extra" init request.
939 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
940 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
942 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
944 Make ZOOM error code for "invalid query".
946 Fixed compilation for SSL which wasn't properly enabled for all platforms.
948 --- 2.0.10 2004/02/05
950 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
953 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
955 Added option -p <file> to make Generic Frontend Server to write PID file.
957 Added option -D to put Generic Frontend Server in background on its own.
959 Make ZOOM C recognize option "password". If unset, "pass" is used
960 (for backwards compatibility).
962 Fixed a bug in Generic Frontend Server that could make it crash if a
963 client sets characterSetNegotation bit, but didn't pass negotiation stuff
966 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
967 Must be issued before open, in order to be in effect.
969 --- 2.0.9-6 2004/01/12 Debian/Windows
971 Make the SRU server more picky WRT unknown params, etc.
973 Bug fix: ZOOM scan response didn't return displayTerm - when present.
975 New YAZ client command, options, that sets Z39.50 options.
977 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
978 options from a string of tokens (one token for each option bit).
980 Update SRW diagnostic code messages.
982 --- 2.0.9-5 2004/01/07 Debian/Windows
984 Handle user defined stylesheet for SRW/SRU.
986 --- 2.0.9-4 2004/01/06 Debian/Windows
988 Fix bug in decoding of Content-Length.
990 --- 2.0.9-3 2004/01/06 Debian/Windows
992 Fix a bug with decoding of XML packed records.
994 --- 2.0.9-2 2004/01/05 Debian only
996 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
998 Fix bug in SRW/SRU diagnostics decoding.
1000 --- 2.0.9 2004/01/05
1002 Fixed bug in Generic Frontend Server which could drop records exceeding
1003 preferred message size. Reported and fixed by Irina Dijour.
1005 Fixed calculation of package size for structured records in Generic
1006 Frontend Server. Reported and fixed by Irina Dijour.
1008 Fixed namespace for SRW/SRU diagnostics.
1010 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1012 --- 2.0.8 2003/12/22
1014 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1015 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1018 CQL changes to reflect recent changes to the specification:
1019 * Documentation talks about context sets instead of index sets.
1020 * Documentation talks about indexes instead of qualifiers.
1021 * The CQL-to-PQF transformer's configuration file now uses
1022 "index.set.name = <attributes>" instead of the old form
1023 "qualifier.set.name = <attributes>". (Both forms are still
1024 understood but the latter is deprecated.)
1025 * CQL terms with no explicit index specified are now interpreted as
1026 cql.serverChoice instead of srw.serverChoice (which of course
1027 behaves exactly the same.)
1029 --- 2.0.7 2003/12/16
1031 MARC conversion can now generate ISO2709 output in another
1032 character set. yaz-marcdump uses this facility if you invoke it
1035 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1036 functions from there can be used from C++.
1038 --- 2.0.6 2003/12/04
1040 Frontend server now transfers memory from decoded packages to stream
1043 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1044 references to show up.
1046 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1047 the ZOOM Abstract API. The older names for the same options are still
1048 also supported for the benefit of old applications.
1050 ZOOM-C supports "implementationId" and "implementationVersion" options
1051 to go along with "implementationName". These allow the user code to
1052 specify identification strings to be sent to servers.
1053 Add OID for the new ExtLite attribute set.
1055 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1056 as requested/supplid by Ere Maijala <ere@atp.fi>
1058 For generic frontend server, reverse the order of
1059 "toolkit-supplied / application-supplied" strings sent as implementationId,
1060 Name and Version. Also, remove the spaces around the slash. This brings
1061 the GFS in line with the behaviour of ZOOM-C on the client side.
1063 Add function ZOOM_scanset_display_term.
1065 yaz-client shows scan displayTerm if present.
1067 Utility yaz-iconv is now installed by default along with the man page
1070 Extend configure check for OpenSSL to use pkg-config where available (such
1073 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1074 server to specify uid/gid/mask for socket using the format
1075 unix:[user=uid,][group=gid,][umask=mask,]file=path
1076 If file= is omitted the existing format is assumed, e.g.
1078 in which case the mask is 0666 (rw for everybody).
1080 Major restructure of YAZ source. All source in libyaz is in src directory.
1081 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1082 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1084 Added man page for utility yaz-marcdump (used to be called marcdump).
1085 yaz-marcdump is installed by 'make install'.
1087 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1088 of incoming package failed.
1090 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1092 Change prototype of odr_perror: add const to message string.
1094 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1096 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1097 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1098 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1099 DNS lookup. There should not be any compatibility problems with this
1100 assuming that blocking=1 or 0 is used.
1102 Fix bad reference in UNIX comstack in function cs_addrstr.
1104 Fix for compilation on AIX.
1106 The generic front-end server (server/seshigh.c) now supports returning
1107 Init diagnostics to the client in User-information-field, in
1108 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1111 --- 2.0.4 2003/09/04
1113 Allow any CQL relation (not just all,any,exact,scr).
1115 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1116 that features the same UI.
1118 Implemented command update0 in YAZ client which is equivalent to
1119 update but uses old of Ext Update ASN.1.
1121 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1122 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1123 Previously no OID was used for this info.
1125 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1126 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1127 returns 'malformed search term' otherwise.
1129 SortResponse member resultCount now set to NULL in sort handler of
1132 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1135 Add three new utility functions for translating OIDs between various
1136 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1137 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1138 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1139 char *oid_to_dotstring(const int *oid, char *oidbuf);
1140 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1142 Reverted modifications for ES Update definition for z_IU0Update
1143 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1144 is back to YAZ 2.0.2.
1146 String value attributes for CCL parser.
1148 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1149 which their FirstSearch server returns in Init responses, sometimes
1150 carrying useful diagnostic information when Init fails. This has the
1151 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1152 "z39.50/oclcui.asn", where its definition is somewhat different from
1153 what OCLC document on their web-site, as required to interoperate with
1156 Support for anonymous authentication in yaz-client. Use the command
1159 * Fix the OID of the Index Data-local "admin" Extended Service from
1160 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1161 the 1000, which indicates a locally-defined OID, was a mistake.
1163 --- 2.0.3 2003/06/20
1165 Fix CCL directive @case handling so that it affects string match for
1166 both CCL keywords and qualifiers.
1168 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1169 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1170 Decoder has been updated with ASN.1 changes as listed in
1171 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1172 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1173 z_IUUpdate, remains unchanged.
1175 ZOOM_record_get may now return a record in a specific character set.
1176 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1177 "from" is the character set of record as returned by target. "to" is
1178 the character set to be returned. If omitted, "to" is UTF-8.
1180 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1182 New ODR utility, odr_getelement, which returns name of element for
1183 which encoding/decoding failed.
1185 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1186 in cases where a required element was omitted.
1188 Bug fix: some MARC8 sequences were not converted.
1190 New ZOOM option "step" which specifies number of records to be
1191 retrieved in one chunk. Used in conjunction with "start" and "count".
1193 SRW support for yaz-client. Use scheme http: to use it, e.g.
1196 yaz-client no longer does (un)intelligent character set conversions
1197 by default. Can be enabled with charset and marc_charset commands.
1199 xmalloc trace fix for 64-bit systems such as DEC alpha.
1201 Solaris 2.6 compile fix.
1203 New function, cql_strerror() translates SRW error codes, as returned
1204 by cql_transform_error(), into human-readable English strings. Used
1205 in yaz-client diagnostics when appropriate.
1207 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1208 converts it into a type-1 query which is sent to the server. This
1209 makes CQL available for use with all Z-servers, as opposed to the tiny
1210 minority that can handle CQL queries themselves.
1212 --- 2.0.2 2003/04/28
1214 New Debian package layout similar to the Redhat Package layout.
1216 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1217 and search result respectively.
1219 --- 2.0.1 2003/04/25
1221 Redhat package is now several packages: libyaz (runtime libraries),
1222 libyaz-devel (development and documentation, and yaz (utility programs).
1223 Package spec file by Morten Bøgeskov.
1225 New member 'schema' in struct bend_fetch_rr which the name of requested
1226 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1227 handler MAY set this to reflect the schema of the returned record.
1229 New member 'display_term' in struct scan_entry. GFS now sets member entries
1230 and allocates scan entries to be filled by user scan handler. In previous
1231 version, entries member was allocated by the scan handler. That still works,
1232 but the GFS will ignore member display_term - assuming it was NOT set by
1233 the handler. The fact that the GFS now allocates the entries both allows
1234 for new members and makes a scan handler easier to write.
1236 Fix CQL lex buffer overflow.
1238 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1239 SRU default recordPacking is string.
1241 SRU protocol support for frontend server.
1243 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1245 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1247 Added scan for the ZOOM shell (zoomsh).
1251 * String Identifers for Schemas (Amendment 5).
1252 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1253 Old definition for schema
1254 Odr_oid *schema; /* OPT */
1259 Z_InternationalString *uri;
1260 #define Z_Schema_oid 1
1261 #define Z_Schema_uri 2
1264 * resultCount parameter to Sort Response (Amendment 1).
1265 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1267 Support for SRW 1.0 over HTTP. This is an optional feature and
1268 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1271 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1272 on the same port. SRW SearchRetrieveRequests are mapped
1273 to bend_init,bend_search,bend_fetch,bend_close.
1275 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1277 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1278 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1280 ZOOM connections are SRW based if schem http is used for hostname
1281 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1282 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1284 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1285 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1286 distance=n, order=true/false, relation=le, prox unit=word. If
1287 n is omitted, distance 1 is used.
1289 Fixed problem with C compiler include path in wrong order.
1291 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1292 on Solaris. Patch from Ko van der Sloot.
1294 New MARC decode API. All new functions operate on a yaz_marc_t
1295 handle. The most important new functions are: yaz_marc_create,
1296 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1297 decode and destroy respectively. Decoder can produce formats
1298 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1299 include/yaz/marcdisp.h.
1301 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1302 to UTF-8, UCS-32, wchar_t or Latin-1.
1304 * Prototypes for yaz_iconv_-functions moved to separate header
1305 include/yaz/yaz-iconv.h.
1307 Make a few private functions 'static' in unix.c. This prevents
1308 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1310 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1311 are set when Init Response is received.
1313 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1314 but returns diagnostic set as well.
1316 New function yaz_strerror which is a portable wrapper for
1317 strerror/strerror_r/GetLastMessage.
1319 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1320 is returned for MARC. If type is "oai", then OAI MARC is returned.
1322 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1325 --- 1.9.2 2002/11/26
1327 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1329 Fix bad race conditions on SIGTERM and terminate gracefully in
1332 Move retrieval (data1) module to Zebra since nobody seems to be
1335 Add GRS-1 render for ZOOM using same format as yaz-client.
1337 --- 1.9.1 2002/10/05
1339 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1341 Fix broken ESpec handling in data1 module.
1343 SGML reader parses comments and makes them part of the data1 tree.
1345 Added several type casts so that YAZ compiles as C++ code.
1347 ZOOM didn't handle PDU encoding failures properly.
1349 Added more Bib-1 diagnostics (approved extensions).
1351 GNU configure: better check for iconv.
1353 More portable use of accept, getpeername. Check for socklen_t. Use
1354 int/size_t if socklen_t is not defined.
1358 PQF parser rejects bad queries - including those with extra
1359 characters in them. PQF parser used to silently ignore that.
1360 Cleaner API for PQF added, which allows you to get detailed
1361 error information for bad queries (see yaz/pquery.h).
1363 Fixed bug in ZOOM_record_get for type "database".
1365 Implemented mini iconv library supporting conversions between
1366 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1368 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1370 --- 1.8.9 2002/08/20
1372 Fixed ZOOM C record cache so that preferredRecordSyntax and
1373 elementSetName is used to check for already fetched records.
1375 --- 1.8.8 2002/08/02
1377 Added three members in bend_initrequest structure to facilitate
1378 character set negotiation.
1380 Fixed a bug in frontend server that could cause indefinite
1381 loops under rare conditions.
1383 Revised character set utilities (charneg.h) so that encoding
1384 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1386 For PQF, directive @term <type> sets term type for Scan/Search.
1387 Here <type> is general, string, numeric, null. The term type
1388 is inherited - just like @attr.
1390 New call odr_set_charset that sets character set conversion for
1391 international-strings on a ODR stream. Prototype is:
1392 int odr_set_charset(ODR o, const char *to, const char *from);
1393 The InternationalString is still represented as C string in YAZ
1394 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1395 won't). On the protocol level, you can use any encoding.
1397 Support for UNIX sockets in ZOOM.
1399 Solaris recv sometimes returns errno == ENOENT. It is treated as
1400 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1402 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1403 both client and server. Code by Morten Bøgeskov.
1405 --- 1.8.7 2002/05/22
1407 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1408 that they can be used directly from Visual Basic. You must recompile
1409 your windows APP if you're using ZOOM.
1411 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1412 Commands "lang" and "charset" sets language and character set respectively.
1413 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1414 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1416 Attributes from multiple CCL fields may be OR'ed rather than merged
1417 using directive "@field or". Fields are still merged by default -
1418 equivalent to "@field merge".
1420 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1423 Fixed bug in zget for parameter ExtendedServicesResponse.
1427 --- 1.8.6 2002/03/25
1429 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1431 Client displays USR.1:SearchResult-1 (hits per term).
1433 Additional Search Info for search in Generic Frontend Server.
1435 Fixed CCL parsing of "field=s".
1437 WIN32 installer - using the excellent NSIS software from nullsoft.
1439 Fixed CCL parsing of "field = - <number>".
1441 Added function yaz_marc_decode that decodes MARC for line mode
1442 display or XML (similar to that used by JZKit).
1444 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1445 Z39.50. But ISO/ILL was, however.
1447 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1448 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1450 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1451 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1453 --- 1.8.5 2002/02/03
1455 New YAZ client features: Command completion and new commands:
1456 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1457 Code provided by Jacob Poulsen.
1459 New call oid_trav, that visits all registered OIDs via callback.
1461 Function ZOOM_record_get now returns const char pointer rather than
1462 void pointer. It saves a lot of type casts.
1464 For YAZ client, command "auth" now allows you to set authentication
1465 in IdPass style. It is enabled when three tokens are given - order
1466 is user, group and password.
1468 Fix memory leaks in MARC record handling for ZOOM.
1470 New option for YAZ client, -k <kilobytes> that sets
1471 maximum record size. Similar to -k option for generic frontend
1472 server and yaz-ztest.
1474 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1476 Prefix query parser reports "fail" when bad attribute set is given.
1478 Fix in MARC decoder. Proximity logging. Fix for attribute set
1479 in scan handler for server. Patches by Shigeru Ishida.
1481 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1484 Configure option --with-openssl=<dir> now works when a directory is
1485 specified. Patch provided by Morten Bøgeskov.
1487 New option for YAZ client, -u <auth>, that sets authentication.
1489 ZOOM fix: error information was sometimes "missing", since error
1490 was cleared/reset too when it shouldn't.
1492 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1494 --- 1.8.4 2002/01/04
1496 Scan for ZOOM API. New object ZOOM_scanset. New functions
1497 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1498 ZOOM_scanset_destroy.
1500 New ZOOM function, ZOOM_connection_last_event, that returns type
1501 of last event (such as "receive data", "send data", "apdu received",
1504 New ZOOM option, schema, that specifies schema for retrieval.
1506 New CCL feature. Qualifiers can be aliases for one or more
1507 other qualifiers (if more than one is given, OR is used).
1509 ZOOM uses named result sets if target supports it.
1511 Two new YAZ client commands: . (dot, which sources a script of YAZ
1512 client commands), and ! (to execute shell command.). Implemented
1515 Working on Debian packages.
1517 --- 1.8.3 2001/11/19
1519 YAZ client enables named result sets only if target supports it.
1521 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1523 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1524 with key="host" to get same result.
1526 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1527 Function Z3950_resultset_record(s) returns references to records
1528 "owned" by resultset. To become owner use Z3950_record_clone.
1530 Function z_ext_record handles Extended Services. Thanks to
1533 --- 1.8.2 2001/11/12
1535 CCL Parser fix: ignore token comma when dealing with and-lists.
1537 Documentation updates for COMSTACK.
1539 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1540 Changed prototype Z3950_records. For some functions, int parameters
1541 were changed to size_t.
1543 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1546 New MARC decode/display function, marc_display_exl, which properly rejects
1547 non-ISO2709 records. YAZ client uses it.
1549 --- 1.8.1 2001/10/29
1551 Fix bug: local attribute set wasn't set correctly in PQF strings.
1555 * Old Z39.50 codecs no longer supported.
1557 Added ZOOM C binding. See http://zoom.z3950.org/
1559 Renamed states for COMSTACKs to avoid confusion with events.
1561 Implemented cs_look and proper cs_rcvconnect.
1563 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1565 Configure detects POSIX threads on OpenBSD.
1567 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1568 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1570 When error is returned from present handler, non-surrogate diagnostic
1571 is returned in present response (and fetch handler is no longer called).
1573 * Minor adjustments to pquery parser (PQF). Token characters may be
1574 escaped by using backslash (C-style).
1576 PQF parser allows string attribute values to be specified. For @attr,
1577 non-numeric characters after the equal-sign are treated as strings
1578 (e.g. @attr 9=title).
1580 CCL trunction character may be defined (@truncation in file)
1582 * function zget_ExtendedServicesRequest sets waitAction to
1583 waitIfPossible (was wait).
1585 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1588 CCL operator names may be set in field definition files (CCL_bibset).
1589 See ccl/bib1 for an example.
1591 Fixes in ASN.1 compiler for C++ compatibility.
1593 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1594 and "op_or" to avoid conflict with C++.
1596 Fixed problem with GNU readline detection on Redhat 7.0.
1598 Added step-size for Scan backend handler.
1600 Fixed bug that made the frontend server crash when no attribute
1601 set was specified for scan.
1603 Front-end server automatically switches to original working directory
1604 when installed as an NT service. Previously -w had to be specified to
1607 Added extended attributes for retrieval module (data1), so that data1
1608 records carry d1_readXML/SGML attributes. d1_read also supports
1609 null-data rules ( <tag/>)
1611 On UNIX when POSIX threads are available, a separate library libyazthread
1612 is created. Programmers should link with that library and the yaz library
1613 when using threads. The reason for the split was that some applications
1614 on Linux, such as Apache, doesn't work well when using shared objects that
1617 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1618 (or any frontend server) in SSL mode by specifying ssl: followed by
1619 address. Only tested on UNIX.
1621 Added feature for CCL module. Virtual structure s=al or s=ol generates
1622 and-list and or-list respectively instead of phrase search.
1626 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1627 log_mask_str. This was done to avoid name conflicts with other libraries
1628 (such as other PHP extensions).
1630 Added raw OID member for preferred record syntax (request_format_raw)
1631 and returned record syntax (output_format_raw) for backend fetch method.
1633 Config file yaz-config now accepts options so that it returns specific
1634 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1636 Shared library support for UNIX using GNU libtool.
1638 * Modified backend interface. Request/Response struct's replaced by
1639 one read/write C struct. For example bend_fetchrequest and
1640 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1641 Every handler - even search has to be registered in bend_init
1642 handler. This means that the YAZ library no longer refers to
1643 external functions and it makes it possible to make the whole
1644 thing a single DLL/SO.
1646 Added Segment handler for backend server.
1648 Added Zmbol/Zebra administrative functions to YAZ client.
1650 Threaded frontend server on UNIX (when POSIX Threads are available).
1651 Starting the server with option -T enables multi-threading.
1655 Added configure option --enable-comp/disable-comp to control use
1656 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1657 located in sub directory asn.
1659 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1660 in ${exec_prefix}/bin along with the other programs yaz-client and
1663 GNU automake used to maintain makefiles.
1665 Added several OID's.
1667 Changed retrieval module so that we can load records with no abstract
1668 syntax defined. Tagpaths in these records are fully composed of string
1671 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1675 On UNIX, the generated makefile now supports a proper 'make install'.
1676 The prefix can be set via GNU configure to set the install location
1677 (default is /usr/local).
1679 * YAZ programs client and ztest were renamed to yaz-client and
1680 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1681 locations, such as /usr/bin,/usr/local/bin,etc.
1683 * YAZ Header files were moved from include to include/yaz. YAZ Header
1684 files are referred to as include <yaz/log.h> rather than <log.h>.
1685 The YAZ include path (-I ..) is therefore the same as before. Programmers
1686 should update their #include statements or use -Ipath/include/yaz
1687 instead. The main motivation for doing this change is that YAZ header files
1688 can be installed in "standard" locations /usr/include,/usr/local/include
1689 without introducing conflicts, since ALL YAZ header files are stored
1690 in subdirectory yaz (under /usr/include for example).
1692 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1693 rather than project/workspace files. We switched because project files
1694 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1697 Changed name of logging function, logf, to yaz_log, to prevent name
1698 clash with some math-log functions. The YAZ header log.h defines logf
1699 to yaz_log (#define) so there should be no incompatibilities by this
1702 Added bend_start/bend_stop handlers for server. These handler are
1703 called on start/stop of server. For windows they are called whenever
1704 a service is started/stopped.
1706 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1707 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1708 in util/yc.tcl. The auto-generated C code structures are, in a few
1709 cases, incompatible with the old decoders. There are differences in the
1710 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1711 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1712 The preprocessor variable ASN_COMPILED is defined when the compiled
1713 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1714 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1715 wish to use the old encoders/decoders you can specify --disable-yc
1718 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1719 version so that it supports both new - and old version of DB Update
1721 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1722 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1723 change. The name parameter can be set to 0 in which no name is specified
1724 for the construction. The macros odr_implicit and odr_explicit sets name
1725 parameter to zero for the construction involved. New macros
1726 odr_implicit_tag and odr_explicit_tag are similar to the others,
1727 except that a name parameter is added. For programmers' that don't use
1728 ODR they probably only need to change the call to z_APDU and z_External.
1730 Added access control facility by interfacing the TCP wrapper library.
1731 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1732 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1733 name of the daemon and enables the access control as specified in
1734 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1736 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1737 den Dool <H.M.vdnDool@kub.nl>.
1739 Added reference ID parameter to most functions in server API - refer
1740 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1742 Changed name of ccl library to libccl.a (was ccl.a).
1744 Fixed bug in decoder for Explain (Category TargetInfo).
1746 Added support for GNU readline in client. Thanks to Jacob Poulsen
1747 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1749 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1750 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1751 IMPLEMENTATION! This change was made to the development version before
1752 the ZIG decided to retract the amendment. If any users MUST be
1753 compatible with the original Update definition, PLEASE CONTACT US, and
1754 we will include a separate definition corresponding to the old Update
1755 ES. Note that because of the change to the ASN.1 of the
1756 TaskPackageRecordStructure we cannot define a single structure that
1757 will support both versions.
1759 * Added const modifier to buffer parameter for some ODR/BER encoding
1760 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1761 completeWAIS, odr_dumpBER.
1763 Fixed bug in client.c which caused a crash when a scanResponse didn't
1764 contain positionOfTerm.
1766 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1767 * will cause an error in a client if a non-YAZ target sends both a
1768 * list of Scan entries and non-surrogate diagnostics.
1770 Retrieval module enhancements. Tag sets may be typed in the reference
1771 to it. From the .abs-file the "tagset" directive takes a third optional
1772 integer type for the tag set referenced. From a .tag-file the "include"
1773 directive takes a third optional type as well. The old "type" directive
1774 in the tag set itself is still recognized but acts as the default type
1777 Backend interface change. Individual Scan terms returned from bend_scan
1778 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1779 in include/backend.h.
1781 Retrieval module enhancements. Multiple tag sets and attribute sets may
1782 be specified in abstract syntax specs. Revised the error/warning for
1783 logging messages reported by the retrieval module when reading the
1786 Object Identifier system (oid_..) changed. The API is backwards
1787 compatible but the oid-routines now allocates new OID's when needed.
1788 Raw OID's may be specified in oid_getvalbyname.
1790 YAZ now uses GNU configure to generate Makefile(s).
1792 * Minor changes in some of the member names of DeleteResultSetRequest and
1793 DeleteResultSetResponse. See include/proto.h.
1795 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1796 and added member 'languages' in TargetInfo (which was missing).
1798 Changed the way attribute sets are handled in the retrieval
1799 module. These are now cached, just like the abstract syntaxes
1802 Changed YAZ so that it links with compiled ASN.1.
1804 Added Explain-schema definitions and mapping routines. The following
1805 Explain categories have been implemented: AttributeDetails,
1806 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1808 Fixed minor bug in Windows version of Server Library.
1810 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1812 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1814 Added EXTERNAL: UNIverse Resource Report (non-standard).
1816 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1817 ENUMERATED and SET OF.
1819 * Added 'const' to some of the char pointer arguments for the
1820 functions, data1_read_node, data1_getelementbytagname,
1821 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1824 Fixed bug in data1_insert_taggeddata - the last_child member of
1825 parent wasn't initialised.
1827 * Changed data1_read_record and data1_read_node so that the supplied
1828 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1829 doesn't refer to any parts of the "SGML"-buffer.
1831 Fixed bug in server library (Windows version of statserv_remove).
1833 * Changed code so that it compiles as C++. The type definition
1834 of Odr_fun which is a member of Odr_arm was changed. The result is,
1835 that an explicit typecast is needed for the fun pointer when
1836 using Odr_arm - as in:
1837 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1839 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1841 Implemented the new structured date and time definition as approved
1842 by the ZIG. Added schemaId element to the specificTag in Espec-1
1843 (also approved at the last ZIG). Thanks to RVDM.
1845 Added some Object identifiers (RVDM).
1847 Changed the Update Extended Service (RVDM).
1849 Added command "refid" to client which specifies referenceId for
1850 the following requests.
1852 Implemented extended service handling for server. See ztest.c
1853 for an example as well as backend.h. New handlers are registerd
1854 in the Init handler.
1856 * Changed interface for sort in server.
1858 Added new members to statserv_options_block. It allows a server
1859 to read options from another source than just the command line. Thanks
1860 to Charles Woodfield.
1862 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1863 renamed to zboolean. Some C++ compilers complained about the name.
1865 Minor changes to gils.abs. Added index 's' (sort) on title
1866 and date/time-last-modified.
1868 --- 1.4pl2 1998/1/30
1870 Fixed bug in server library regarding inetd mode (-i). This bug
1871 was introduced by release 1.4.
1873 --- 1.4pl1 1998/1/29
1875 Added sort facility in client and backend server interface.
1877 Fixed problem with dependencies in Makefile(s).
1879 Fixed bugs for encoders/decoders of extended services and
1882 Implemented sub-tree feature for schemas. Sub-trees are
1883 referenced in *.abs-files. See explain.abs for an example
1884 of the use of this feature.
1886 Modified bib1.att; local attributes for ANY didn't include
1887 ANY itself (only affects use of the retrieval module).
1889 Fixed bug in plain SGML reader in function data1_read_node:
1890 tags with prefix "var" was incorrectly interpreted as variants.
1892 Added feature "sub-schemas" to enable references to - and definitions
1893 of - group of elements.
1895 * Removed member parent from type data1_element (in data1.h).
1897 Implemented function odr_nullval() that returns the value of
1900 * Removed member num_children from data1_node (in data1.h).
1902 Made NT service interface part of the server library. The
1903 function statserv_main uses the NT service when required and
1904 calls the statserv_start / statserv_close routines.
1906 Routine zget_SearchRequest and zget_PresentRequest fills
1907 resultSetName/Id member with "default" instead of "Default".
1909 Fixed memory leak in server. Request queue member wasn't freed.
1911 Fixed nmem_exit so that memory is freed.
1915 Revised the CCL parser utility to be thread safe.
1917 Added function, oid_ent_to_oid, to replace the function
1918 oid_getoidbyent, which is not thread safe.
1920 * Added nmem_init and nmem_exit to initialize and release
1921 NMEM resources. Function nmem_init should be called once in the
1922 initial thread before NMEM/ODR is used. statserv.c and client.c
1923 have been changed accordingly. The change was necessary to make
1924 NMEM thread safe. The NMEM memory pool is shared amongst threads
1925 in a process. Unix-based applications will still work fine without
1928 Added NT Services interface for the the Z39.50 (statserv) Server.
1929 Refer to the ztest.c source on the usage.
1931 Windows 95/NT port using MSVC5.0. Project files are included in the
1934 * Defined new 'global' handle for the retrieval (data1) system. The
1935 new handled, data1_handle, describes the state of the data1 system.
1936 This handle is passed as first argument to virtually all
1937 data1 related routines. The functions data1_create and data1_destroy
1938 creates and destroys a data1 handle respectively.
1940 Added ODR encode stream member to all backend request structures
1941 init, search, scan etc. This stream should be used to allocate all
1942 memory used for the response when thread safe operation is needed.
1944 Changed the comstack utility, cs_addstr, to be thread safe. The
1945 returned hostname string returned by the function is now part the
1948 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1949 function. The cs_straddr takes a COMSTACK handle as argument, so this
1950 function must be used after cs_create and before bind/connect.
1951 This function is thread safe.
1953 Moved test server to 'ztest' directory - generic server code still
1954 in 'server' directory.
1956 Made prefix query (pquery.c) utility thread safe.
1958 Added new function modifier YAZ_EXPORT to 'export' public DLL
1959 functions when using windows (see include/yconfig.h).
1961 Added definitions to the OID database (util/oid.c) (RVDM).
1963 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1965 Added call to ccl_rpn_delete in client program.
1967 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1968 release of RPN structure.
1970 Added support for C++, headers uses extern "C" for public definitions.
1971 With input from RVDM.
1973 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1974 Thanks to Ronald van der Meer (RVDM).
1976 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1978 Added support for private extensions to the OID database
1979 (oid_setprivateoids()). Thanks to RVDM.
1981 Added optional, physical ANY (key replication)
1983 Fixed null-reference problem in GRS-1 output filter.
1985 Proximity operator added to Prefix Query Format (PQF).
1987 In test client command "base" accepts multiple databases.
1989 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1993 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1995 Smallish bug-fixes in the new encoders/decoders (explain).
1997 Bug fixed in DeleteRequest.
1999 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2001 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2003 Added SOIF syntax (using private OID for now) to retrieval module and client.
2005 Added Update extended service.
2007 Added SearchResult-1 additional info structure.
2009 Added optional CCL (ISO8777) interpreter as separate module. Available
2012 --- 1.2 1996/6/10 (1st anniversary release)
2014 Added Summary record syntax. Lightly tested.
2016 Added OPAC record syntax. Untested.
2018 Added ResourceReport service encoders/decoders. Untested.
2020 Fixed bug in z_Unit - wrong tagging on unitSystem.
2022 Fixed bug in the DiagRecs decoder.
2024 Added options for max PDU size and session timeout to frontend-server.
2026 Added documentation of query-language parsers and other supporting utilities.
2028 [frontend-server] Added Attribute set to the bend_scanrequest API.
2030 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2031 surrogate diagnostics were generated.
2033 [retrieval] Allow multiple local values for attribute.
2035 [retrieval] Allow multiple attributes per element in .abs files. index type.
2037 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2039 --- 1.1pl2 1996/4/10
2041 Minor changes, mostly specific to Zebra's requirements (retrieval)
2045 Repaired bug in frontend server when running multiple listening
2046 endpoints in dynamic mode.
2048 z_External() now won't break if a known, ASN.1 value comes encapsulated
2049 in an octet-string. The value will pass through unmodified in an Odr_oct.
2051 Added a bit of code to the demo client to decode & display
2052 ASN.1-structured records represented in the octet-aligned branch of
2053 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2055 Added z_ext_getentbyref() to the ASN module. Doc updated.
2057 * Completed the SCAN definition in the ASN module. This may break SCAN
2058 code based on older YAZ-versions at compile-time. The fix is easy -
2061 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2062 under the SCAN definition. Remember to initialize this, server-people.
2064 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2065 that this does not extend to ODR and ASN.
2067 Comstack allows insertion of established socket (primarily for
2068 inetd-operation of servers). Doc updated.
2070 Front-end server can now start from the inetd in TCP mode. Doc
2073 --- 1.0pl4 1996/1/24
2077 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2078 the rank and record number.
2080 Adjustments to the frontend server.
2082 Fixed diagnostic BER dumper. It ignored the file argument.
2086 Various changes to retrieval module.
2088 Changed the union discriminators of the protocol files from enums to
2089 ints paired with #defines.
2091 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2094 *Changed operator in the RPN structure to 'roperator', again to avoid a
2097 Fixed problems in Explain decoders/encoders.
2099 --- 1.0pl2 1995/12/6
2101 Memory bug in log module fixed.
2103 --- 1.0pl1 1995/12/5
2105 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2107 Bug in Explain DatabaseInfo module fixed.
2109 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2113 The shift to v1.0 signals that we now consider the *core* functionality
2114 of YAZ reasonably stable (the core being more or less equivalent to
2115 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2116 tested (Explain not at all - though that will happen soonish).
2118 Minor changes to code to support Windows port.
2120 Various minor changes after we're getting to use GRS-1 & co. more.
2122 Added Espec-1 format.
2124 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2125 of the protocol and it cannot be selected when encoding (maps into 'string'
2126 when decoding). Needed to talk to some servers.
2128 Demo client can request simple element set names.
2130 Added Diagnostic Format encoders/decoders.
2132 Added simple Close handling to frontend server (no hooks for resource
2133 reporting yet), and demonstration client.
2135 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2137 --- 1.0b3 1995/08/24
2139 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2140 handled incorrectly when records were requested in the searchResponse. This
2141 will only affect you if you use the frontend-server.
2143 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2144 Test-client will ask for and print GRS1. Ztest will return dummy records
2147 Added Explain encoders/decoders to the service-level API. Untested.
2149 Added Extended Services: Item Order encoders and decoders to the Service-
2150 level API. Untested. We could use a recent copy of the pertinent bits
2151 of the ILL protocol to add those bits.
2153 Added diagnostic format 1 encoders/decoders to the service-level API.
2156 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2157 odr_cons.c, which causes a more correct output.
2159 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2160 was always set to 0 when no records were requested in the searchRequest.
2162 * Added better external-handling. This shouldn't harm old code that
2163 *encodes* externals. It can break code that looks for a
2164 'single-ASN1-type' representation, since those types that are known
2165 are now decoded immediately. Look at the SUTRS sample code in
2166 seshigh.c and client.c. Documentation updated.
2168 Handling of structured records in bend_fetchresponse. Length -1 marks
2169 structured record, type is deduced from format field.
2171 --- 1.0b2 1995/06/27
2172 Fairly quick maintenance release to add SUTRS support.
2174 Fixed handling of SUTRS records in the demonstration client.
2176 * Added format field to the bend_fetchrequest and bend_fetchresponce
2177 structures of the backend API (frontend server). When the record is
2178 returned, the value of the format field is mapped to an OID. The
2179 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2180 of the record. The special value VAL_NONE in the bend_request means
2181 that no specific format was requested by the client. Documentation
2182 updated accordingly. Test server (ztest) will return a fixed dummy
2183 SUTRS record if your client requests SUTRS.
2185 Documentation updated accordingly.
2187 You can now set external libraries and RANLIB support in the top-level
2191 First public release.
