3 Added new member 'query_charset' for bend_initrequest structure. A
4 backend init handler should set this member to its native character set
5 for query terms. When defined, the frontend server logic will announce
6 this character set to a client if the negotiationModel bit is set by the
7 client. ALL server implementors are encouraged to specify this. If they
8 don't, a warning is issued.
10 Added CCL utility to remove terms (stop words) from resulting RPN
11 tree. This is handled by functions with prefix ccl_stop_words_ .
13 New ZOOM C option, "rpnCharset", which allows client-side conversion of
16 Clean-up the CCL API. Moved some internal structures from ccl.h to
17 private header cclp.h. Changed ccl_parser_create so that a Bibset must
18 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
19 This is replaced by ccl_parser_find_str which takes a string instead.
21 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
22 libyaz.la is the core of YAZ except the generic frontend server and
23 does not depend on POSIX threads anymore. libyaz_server.la is the
24 generic frontend server facilities and uses POSIX thread functionality
25 if available. The libyaz.la no longer depends on POSIX threads because
26 the number of global structures is limited. NMEM no longer re-uses blocks
27 between threads ; it simply free's memory immediately but allocates in
28 "large" chunks as usual. We don't expect any performance penalties
29 because of this. The yaz_log system is still using a global log_level so
30 caution must be taken when modifying it with yaz_log_init_.. +
31 yaz_log_mask_str. This, however, should not cause any trouble because
32 these functions are called during initialization of application code
33 anyway. `yaz-config --libs server` returns libs for server applications;
34 `yaz-config --libs` returns libs for non-server applications.
36 New OID database - with public definitions in oid_db.h. Removed old OID
37 database including the head oid.h and definitions such as enum oid_value
38 and struct oident. The new OID database uses the same string names as
39 before but the 'protocol' is gone. There are now only two representations
40 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
41 converts from string to OID; functions with prefix yaz_oid_to_string
42 converts the other way.
44 Change to emit_term() in CQL-to-PQF query translation: when a term has
45 the /regexp relation modifier, do not process it for leading and
46 trailing "^" and "*", which have quite different meanings in regular
49 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
50 write handlers no longer carries a 'last' parameter. This will make
51 yaz_iconv flush "less" characters. A flush is performed by call to
52 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
54 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
55 removed, because function yaz_query_to_wrbuf does the same.
57 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
58 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
60 Deprecated MARC utility functions removed.
62 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
65 Branch split: YAZ_2_1_55_branch
69 Fix to ZOOM-C so that transparent reconnection is properly handled on
70 connections that are in asynchronous mode.
72 Fixed compilation on OpenBSD 4.0.
74 Large strings in GRS-1 records are now properly displayed in yaz-client.
76 Added character conversion support for "advancegreek"; based on patch from
79 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
80 sequence is met. Before the error was not set so it would be unknown.
82 Adjust yaz-marcdump MARC reader so that it skips until record separator
87 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
88 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
89 fd_set structure used as a bitmask for the FDs to be selected on.
91 Using ACX_PTHREAD macro to check for POSIX threads.
93 Fixed have-vsnprintf check.
97 Fixes for configure on BSD. Bug #900.
99 Added snprintf/vsnprintf wrappers for systems that don't have
100 limits (heavens forbid).
102 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
103 created before all previous tasks were completed and removed from the
104 task queue, the new task could be removed by a mistake.
106 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
108 Implemented pass-through CQL-to-PQF conversions. Bug #861.
110 Fixed bug #832: Problem with MARC/charset in yaz-client.
112 Fixed bug #668: save command line history for yaz-client.
114 Fixed bug #830: pkg-config support.
116 --- 2.1.48 2007/01/23
118 Extended ZOOM result set options with two options that may be read by
119 a client: resultSetStatus and presentStatus with values as specified for
121 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
123 Fixed bug #827: Using SSL fails on Debian etch.
125 Fixed bug #826: Weird looking chars for set of MARC records.
127 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
128 that is treated as an ItemOrder with itemRequest being an XML document
129 external. The value of "doc" is the content.
131 Extended the GFS search facility. New member of bend_search_rr
132 'estimated_hit_count' signals that hits is known to be an estmate
133 (higher or lower than real hit count). New member 'partial_resultset'
134 signals that the search was partial (hit count is lower or equal than
135 real hit count). For Z39.50, the information is stored in resultSetStatus
136 member of SearchResponse APDU. For SRU, the information is signalled
137 via SRU diagnostic 59: "Result set created with valid partial results
140 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
142 --- 2.1.46 2007/01/13
144 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
146 Added ZOOM_connection_peek_event.
148 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
149 the following new functions:
150 ZOOM_event_nonblock, ZOOM_connection_process,
151 ZOOM_connection_get_{socket,mask,timeout},
152 ZOOM_connection_fire_event_{timeout,socket}.
153 The existing blocking event handler, ZOOM_event, is a wrapper for the
154 + blocking ZOOM_event_sys_{poll,select}.
156 Implemented function ccl_xml_config which parses XML version of CCL
157 configuration (bug #798).
159 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
161 Added timings utility (yaz/timing.h)
163 --- 2.1.44 2007/01/03
165 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
168 Fixed bug #779: Rotation of apdu.log fails.
170 Fixed for character set conversions:
171 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
172 Honor G1 set in MARC-8 decoding.
174 --- 2.1.42 2006/12/17
176 Fixed bug #775: char conversion does not handle Alternative UTF-8
179 Implemented function yaz_marc_read_line which parses MARC line format
180 records. There is a wealth of formats out there. So far, this function
181 reads line records produced by yaz_marc_write_line.
183 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
184 more generic and easier to remember(!) options: -i format and -o format
185 which specifies input format and output format respectively - where
186 format is one of "marc", "marcxml", "line", "marcxchange".
188 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
189 does not print anything except warnings for records.
191 For yaz-marcdump, added support for MARC split into files (-s) with a given
194 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
195 spec, at http://www.loc.gov/standards/sru/record-update/
196 This has changed the binary layout of the following structs:
197 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
198 bend_update_rr . Patch by Ko van der Sloot.
200 Added GFS utility function bend_assoc_is_alive which returns 1 if
201 association is still alive (client is connected); 0 otherwise (client
202 closed connection). This allows busy servers to stop working for
205 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
206 been a separate piece of software. This version of ziffy has been modified
207 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
209 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
211 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
212 Client code may now interrogate options such as "init_opt_sort" to
213 find out whether the server claims to support various options.
215 --- 2.1.40 2006/11/27
217 Added utilities yaz_{set,get}_esn to set/get element set name from
220 Removed the build of libyazthread.la. The libyaz.so is the threaded version
221 of YAZ and has been so since YAZ 2.1.10.
223 Implemented ZOOM_record_error which returns error information for
224 record (surrogate diagnostic).
226 --- 2.1.38 2006/10/31
228 Updates for SRU Update by Ko van der Sloot:
229 1. Changed name from "operation" to "action"
230 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
231 versions in the code, marked as 'backward compatible'.
232 3. Added diagnostics for SRU Update.
234 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
236 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
238 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
240 For GFS, fixed problem with SRU diagnostic 'First record position out of
241 range' being issued for 0 hits.
243 zoomtst10 part of Windows Build.
245 --- 2.1.36 2006/10/13
247 Implemented yaz_filepath_comp which splits a path into file path
248 components (required by Zebra 2.0.3+).
250 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
251 BSD inspired license until now so this should not have any real impact on
252 anybody. See http://www.opensource.org/licenses/bsd-license.php
254 Fixed bug #687: Missing log lines.
256 Fixed bug #678: CQL to PQF translation does not preserve double-quote
259 Fixed bug #689: SRU diagnostics to be added.
261 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
262 whether a connection is idle (no more work do do).
264 --- 2.1.34 2006/10/04
266 Change type of optval from long to int for invocation of setsockopt with
267 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
269 Added support for specifying the max log file size for the Generic
270 Frontend Server. The size is given with option -r.
272 --- 2.1.32 2006/09/21
274 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
276 --- 2.1.30 2006/09/17
278 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
281 Fixed bug in Generic Frontend Server that could cause a server to stop
282 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
284 For the generic frontend server, the maximum record size is used as maximum
285 size of incoming packages (SRU + Z39.50). The value until was previously
286 only used in Z39.50 Init negotiation and, later, in a session controlled
287 sizes of records returned. This is controlled using -k option. It can be
288 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
290 --- 2.1.28 2006/09/04
292 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
295 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
297 New option for yaz-marcdump -lpos=value which allows setting a portion
298 of MARC header to a certain value.
300 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
302 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
303 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
305 --- 2.1.26 2006/08/15
307 Fixed problem with SRU mode type (soap, get, post) for yaz-client
310 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
312 --- 2.1.24 2006/08/08
314 Fixed MARC ISO2709 encoding routines to deal with character set
317 Minor changes to GFS logging. Database included in search request log
320 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
321 cached/multiple records.
323 Shared libraries are built by default on Unix+configure.
325 Changed cql2pqf transformation to use a different evaluation order. The
326 new order is: always, relation, structure, position, truncation, index
327 and relationModifier. Old order was: always, relation, relationModifier,
328 structure, index, position, truncation. Note that the the latter ones
329 override former ones for identical attributes.. The new scheme means that
330 it is possible to override any existing attribute with a relationModifier.
331 And also that it is possible to override everything for the index rule
332 (except the ones listed in relationModifier). No order is perfect but this
333 one, we believe, covers more real cases.. The "always" should have been
334 called "default", since the attributes there can be overridden with all
337 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
338 compilation phase, but also for yaz-config --cflags output. This allows
339 us to have public headers with Libxml2 stuff in them . It should also,
340 eventually, make Libxml2 checks redundant in packages using YAZ, such
343 --- 2.1.22 2006/06/15
345 Changed SRU update structure bend_update_rr so that SRU diagnostics are
346 stored in uri, message and details.. Previously diagnostics were stored
347 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
348 compatibility.. but he's probably the only one affected, so.
350 Added support for CCL, compiled on the client side, in ZOOM-C. This
351 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
352 input; the resulting query objects can be used for for searching with
353 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
355 YAZ' configure searches for OpenSSL by default.
357 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
358 SL_CTX_use_certificate_file. See
359 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
360 for more info. Thanks to Ko van der Sloot.
362 --- 2.1.20 2006/06/02
364 Bug #600: SRU GET, POST support for yaz-client. Introduced
365 command 'sru' which selects method SOAP/GET/POST.
367 Allow missingValueAction to be specified for the sortspec string -
368 function yaz_sort_spec. By default, the missing value action is null.
369 Use ! to specify "abort". Use = followed by stringvalue to specify default
372 Ensured that Present-handler (if defined) is called in GFS before any call to
373 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
374 searchRetrieve requests.
376 Documentation for YAZ is now based on the Docbook XML/XSLT using
377 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
378 is no longer depending on jade/openjade or docbook-to-man scripts.
379 PDF is no longer part of the distribution - but can optionally be
380 made using DSSSL/jadetex or FOP.
382 Added retrieval handling support in Generic Frontend Server to support
383 conversion between MARC/XML as well as XSLTtransforms. See
384 etc/yazgfs.xml for an example.
386 Added Authentication support to Generic Frontend Server in SRU
387 mode. Authentication using HTTP Basic is supported, as is the use
388 of 'x-username' and 'x-password' parameters in the request itself.
390 Added support for a new character set MARC8s identical to MARC8 except
391 that it converts combined characters to single Unicode characters in the
392 Latin-1 range (when possible).
394 --- 2.1.18 2006/04/24
396 ASN.1 compiler 0.4: generates brief Doxygen file header for
397 generated .h/.c files.
399 Utility yaz_iconv now supports conversion to MARC-8.
401 New facilities for the MARC module. The reading - and writing of
402 content are separate methods for the yaz_marc_t handle. The following
403 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
404 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
405 format). Write functions have prefix yaz_marc_write_.. The existing
406 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
407 available. Removed support for OAI-MARC and simplexml (not the
408 simplexml from PHP5).
410 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
411 to be returned for this connection.
413 --- 2.1.16 2006/03/31
415 Allow multiple languages and charsets to be specified with
416 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
417 negcharset iso-8859-1,utf-8
419 Translation of proximity nodes from CQL into PQF now works.
421 Moved to automake 1.8, 1.9.
423 Added function yaz_log_set_handler which allows a log handler to be
424 installed. This handler will be called for all log messages. Output
425 to file is also produced; but that can be disabled by passing NULL
426 fname to yaz_log_init_file.
428 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
430 For SRW (including GFS), accept application/soap+xml as content-type
433 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
434 produces NO stylesheet reference even if a default stylesheet is specified
437 --- 2.1.14 2006/03/14
439 Updated Windows package to include yazd.dll + yazd.lib for the
440 Development component.
442 If the environment variable YAZ_LOG is set, then it is used as a
443 string indicating the default level of logging to use if not
444 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
445 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
446 used as before. So, for example, to omit warnings from YAZ logging,
449 cql_transform() now map structure and other attributes before indexes,
450 so that index-specific structures and other attributes can override
451 defaults. So now a combination of mapping specifications such as:
453 index.dc.date = 1=date-modified 4=5
454 does the right thing.
456 cql_transform() now also respects the "always" mapping specification,
457 which establishes an initial set of attributes to be used for all
458 terms except where overridden by more specific attributes associated
459 with the index, relation or modifier.
461 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
462 which mode to use; one of "post", "get" or "soap" (SRW, default).
464 Fixes for yaz_iconv routines: changed trie-based character set conversions
465 to use only non-negative values for bit fields due to Sun's C compiler not
466 supporting negative values.
468 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
469 sequences where not read correctly. Fix by Rustam Usmanov.
471 Updated win/makefile to use options, settings which makes things
472 compile with VS C 2005.
474 --- 2.1.12 2006/02/01
476 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
478 In ZOOM socket code, use select instead of poll on MacOSX.
480 ZOOM-C now support client-side compilation of CQL into RPN that is
481 sent to the server, enabling CQL to be used against all Z39.50
482 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
483 ZOOM_query object, and submit it using ZOOM_connection_search().
484 The CQL-to-RPN translation uses a configuration file, the name of
485 which must be specified in the Connection's "cqlfile" option.
487 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
488 function, which takes as its start-term parameter a ZOOM_query object
489 (which may have had either CQL or RPN set into it).
492 --- 2.1.10 2005/11/29
494 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
495 GFS to support this as well. Backend handler, bend_srw_update, does the
496 update work. Code contributed by Ko van der Sloot.
498 Allow retrieval of Search Result-1 information in ZOOM by the use of
499 options that are attached to a result set. ZOOM documentation updated
502 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
503 UTF-8 conversion. Patch by Raj Patel.
505 Added option -m to GFS to control formatting of timestamps in log file.
507 Added 'exit' as synonym for 'quit' in yaz-client
509 Added support for specifying SRW resultSetId + resultSetIdleTime in a
510 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
511 for the new members. Patch by Ko van der Sloot.
513 Added support for SRU POST. It is supported for content-type
514 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
516 Do not build the separate Multi-threaded (MT) library libyazthread.la.
517 Instead make the library libyaz.la multi-threaded. Threading as a whole
518 can still be disabled by configure option --disable-threads. Previosly,
519 with older GLIBCs there were problems with MT libs under Apache. This
520 has now been fixed a long time ago.
522 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
525 CQL module modified to be case insensitive for relations/indexes/operations.
527 Fixed bug in CQL transform code: incorrect value relationModifieder
530 Added 'show all' command for yaz-client which retrieves all results
533 Added new yaz-client, xmles, which takes a (private) OID and
534 a document to be sent as an extended service request.
536 Describe new yaz-client commands wait_response and set_auto_wait.
538 Increase TCP/IP listener backlog from 3 (which I am guessing was
539 copied from the SunOS manual entry way back when) so SOMAXCONN, so
540 that the socket will queue as many incoming connections as it's able
541 to handle ongoing connections. In other words, it will never now
542 refuse a connection that it would be able to handle merely because
543 it's not got around to accepting() enough of the pending connections
544 yet. This is the behaviour anyway under Linux, where the listen()
545 argument is ignored; but not under BSD and on systems such as
546 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
547 YAZ-based servers should now be uniform across operating systems in
550 yaz-marcdump uses 64-bit file access on some systems. This is enabled
551 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
552 This allows yaz-marcdump to read large MARC batches (>2 GB).
554 Modified all YAZ source files - except the source which is auto-generated
555 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
558 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
559 corresponding to the existing *_setl() function. These allow option
560 values containing arbitrary valuues.
562 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
563 ZOOM_resultset_sort() in new applications. Its behaviour is identical
564 except that it returns an indicator of whether or not the sort
565 criterion was accepted (0 for OK, -1 for invalid).
569 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
570 MARC output rather than returning "new" buffer.
572 yaz-client warns about unknown init options.
574 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
578 Added support for SRW sort in Generic Frontend Server. Patch
579 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
580 sortKeys - or NULL if none is provided.
582 Fixed bug #307: It was impossible to specify indefinite/no timeout
583 for ZOOM_event. Special timeout value -1 now means indefinite timeout
586 Added support for multiple languages and charsets to be specified in
587 ZOOM. Each charset/language is separated by a blank. If negotiation is
588 in effect in init-response, Option
589 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
590 Code based on patch by Vasiliy Osadchuk.
592 Fixed bug #306: infinite recursion that occurred when calling
593 yaz_log_level_init as the first call (before other log level or
596 Fixed bug in scan handling in front end server: if preferred-Position-In-
597 Response was non-present, a NULL pointer referece was performed.
601 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
602 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
603 now defined for all those error codes. So instead of putting 109 in
604 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
605 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
607 Modified the yaz-marcdump utility to skip garbage bytes between MARC
610 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
612 Program yaz-client now exits and produces an error message if multiple
613 Z39.50 servers are specified on the command line (none or one allowed
616 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
621 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
623 Fixed bug #272: Preserve spacing for CCL terms.
627 Added support for virtual hosts and multiple backend servers for
628 the YAZ frontend server. The configution is XML based and
629 support specificition of CQL to RPN mappings and explain information.
630 See section "Virtual Hosts" in the YAZ manual.
632 Extended OPAC display utility. OPAC display utility renders
633 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
634 to supplement yaz_marc_decode_wrbuf.
636 Fixed a bug in MARC decoder that could caused it to crash for some
637 invalid MARC records. More diagnostics and warnings where added in
638 XML output (warnings, etc are stored in comments).
640 --- 2.0.34 2005/02/08
642 Fixes for UNIX domain sockets. Bug #261.
644 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
646 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
647 Added yaz_marc_subfield_str which defines subfield lead string which is
648 used in YAZ_MARC_LINE format. Default string is blank+$. Added
649 yaz_marc_endline_str which defines end of fields string used in
650 YAZ_MARC_LINE format. Default string is newline.
652 Experimental support for MarcXChange. This format can be produced
653 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
654 http://www.bs.dk/standards/MarcXchange.xsd
656 Added yaz-client commands scansize that sets maximum number of
657 entries to be returned by scan.
659 --- 2.0.32 2005/01/11
661 Added support for SRW scan in yaz-client and Generic Frontend Server.
663 * Added whereInList member to SRW Scan Term.
665 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
667 Fixed NMEM system to return aligned blocks on the smallest boundaries
668 that are suitably aligned for all possible types on the particular
669 architecture YAZ is being built for.
671 --- 2.0.30 2005/01/04
673 Fixed numerious warnings that was issued with newer versions of GCC.
675 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
676 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
679 Make YAZ Generic Frontend Server slightly faster.
681 Enhance (and reduce) logging for Generic Frontend Server.
683 Revert YAZ log system so that it flushes every write operation
684 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
686 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
687 instead of LOG_, due to name clash with syslog(3). LOG_ are still
688 present. New applications should define YAZ_USE_NEW_LOG=1 - this
689 will effectively disable old definitions.
691 --- 2.0.28 2004/11/09
693 Added yaz_log_time_format which specifies log format using
696 Added yaz_log_module_level which returns mask for a module. Value
697 is non-zero mask a if module is enabled; zero if disabled.
699 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
700 in include/yaz/cql.h.
702 Fixed bug #176: Dont throw diagnostics on empty SRU args.
704 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
706 Fixed bug #172: RPM builds does not enable SSL.
708 Doxyfile.in part of dist. Doxyfile generated by configure.
710 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
711 are given and the corresponding component does not exist.
713 Extend CCL documentation in YAZ reference. Describe r=r.
715 --- 2.0.26 2004/10/01
717 Fixed MARC->MARCXML conversion to properly deal with
718 fields, subfields, indicators having non-ASCII characters.
720 Fixed MARC->MARCXML conversion so that ASCII control characters
721 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
724 Added YAZ GFS support for conversion from Z39.50 surrogate
725 diagnostics to SRW surrogate diagnostics.
727 Bug fix: YAZ GFS did not return schema in explainResponse.
729 --- 2.0.25 2004/09/30
731 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
732 now converts recordSchema to elementSetName as well as schema URI.
734 Fixed bug in COMSTACK that prevented HTTP request packages from being
737 --- 2.0.24 2004/09/29
739 Added CCL facility r=r "range" which is similar to r=o "ordered" but
740 does not require white-space before and after the dash in a range, e.g.
741 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
744 Fixed a few AC_TRY_LINK configure tests that did not operate properly
745 due to new GCC removing "redundant" code.
747 Added yaz-client commands scanpos and scanstep that sets preferred
748 position and step-size for scan.
750 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
752 Added CCL utility ccl_qual_buf which parses one or more CCL
753 spec lines in a buffer.
755 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
756 of name and value - ignoring empty lines and comments.
758 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
760 Added odr_get_element_path which returns current element path for an
761 ODR handle. This utility is useful in error handling or user-defined
764 Added ODR_PRINT utility odr_set_stream which is is a more generic
765 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
766 to a write function and pointer to close function. The close function - if
767 non-NULL - will be called during odr_destroy.
769 Fixed bug in CCL parser where truncation char was not removed from
770 right side when truncation=both was in effect.
772 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
775 --- 2.0.23 2004/08/11
777 Fix buffer overrun in CQL parser when dealing with proximity (%).
779 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
780 to UTF-8/UCS conversion is now only based on codetables.xml.
782 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
784 --- 2.0.22 2004/08/06
786 Add support for more "commit changes" in ZOOM (uses Extended Services).
788 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
791 Yet another small fix for configure of SSL.
793 --- 2.0.21 2004/05/14
795 Fix SSL libs for configure when --with-openssl=DIR is given.
797 --- 2.0.20 2004/05/10
799 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
801 SSL comstack now uses yaz.pem certificate file on server side
802 by default. Certificate filename can be configured by calling
803 comstack function cs_set_ssl_certificate_file before cs_bind is used.
805 Fix bug regarding multiple calls to ZOOM_connection_connect.
807 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
809 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
810 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
812 ZOOM now allows inspection of X509 peer certificate for verification.
813 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
815 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
816 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
817 as "modular" but it simplifies things.
819 Added cs_get_peer_certificate to that returns peer X509 PEM.
821 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
822 NULL if SSL is unavailable.
824 Documentation about MARC decoding tools.
826 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
828 --- 2.0.19 2004/03/30
830 Rename CHANGELOG to NEWS to follow GNU style packing.
832 Fix bug with missing initialization of member in init_diagnostics.
833 This bug affects threaded version of GFS server.
835 --- 2.0.18 2004/03/20
837 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
840 Ensure zlib.dll is packed with Windows install.
842 --- 2.0.17 2004/03/17
844 Fix encoding of xsd:string to use text instead of CDATA.
846 Fix endless loop in CQL parser with unbalanced ".
848 Use a more compact way to store MARC-8 conversion tables.
850 --- 2.0.16 2004/03/16 Debian only
852 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
855 Update CQL parser to use new CQL 1.1 modifiers for booleans and
860 --- 2.0.15 2004/03/01
862 Another fix for decoding of XML packed records.
864 --- 2.0.14 2004/02/25
866 Fixes for Chunked encoding. White space not ignored after length spec.
868 Update NS and use default NS for SRW diagnostic elements.
870 --- 2.0.13 2004/02/23
872 Implement ZOOM_resultset_cache_reset which resets record cache.
874 Implement ZOOM_resultset_sort which sorts a result set.
876 Implement chunked HTTP transfer.
878 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
880 --- 2.0.12 2004/02/16
882 Added member 'schema' to bend_explain_rr structure so that backend
883 can specify explain record identifier. Defaults to Zeerex 2.0.
885 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
887 --- 2.0.11 2004/02/16
889 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
892 Added init command for yaz-client which sends "extra" init request.
894 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
895 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
897 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
899 Make ZOOM error code for "invalid query".
901 Fixed compilation for SSL which wasn't properly enabled for all platforms.
903 --- 2.0.10 2004/02/05
905 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
908 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
910 Added option -p <file> to make Generic Frontend Server to write PID file.
912 Added option -D to put Generic Frontend Server in background on its own.
914 Make ZOOM C recognize option "password". If unset, "pass" is used
915 (for backwards compatibility).
917 Fixed a bug in Generic Frontend Server that could make it crash if a
918 client sets characterSetNegotation bit, but didn't pass negotiation stuff
921 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
922 Must be issued before open, in order to be in effect.
924 --- 2.0.9-6 2004/01/12 Debian/Windows
926 Make the SRU server more picky WRT unknown params, etc.
928 Bug fix: ZOOM scan response didn't return displayTerm - when present.
930 New YAZ client command, options, that sets Z39.50 options.
932 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
933 options from a string of tokens (one token for each option bit).
935 Update SRW diagnostic code messages.
937 --- 2.0.9-5 2004/01/07 Debian/Windows
939 Handle user defined stylesheet for SRW/SRU.
941 --- 2.0.9-4 2004/01/06 Debian/Windows
943 Fix bug in decoding of Content-Length.
945 --- 2.0.9-3 2004/01/06 Debian/Windows
947 Fix a bug with decoding of XML packed records.
949 --- 2.0.9-2 2004/01/05 Debian only
951 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
953 Fix bug in SRW/SRU diagnostics decoding.
957 Fixed bug in Generic Frontend Server which could drop records exceeding
958 preferred message size. Reported and fixed by Irina Dijour.
960 Fixed calculation of package size for structured records in Generic
961 Frontend Server. Reported and fixed by Irina Dijour.
963 Fixed namespace for SRW/SRU diagnostics.
965 Fixed SEGV in yaz-client that occured for HTTP connection errors.
969 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
970 this version is incompatible with version 1.0 and older YAZ SRW/SRU
973 CQL changes to reflect recent changes to the specification:
974 * Documentation talks about context sets instead of index sets.
975 * Documentation talks about indexes instead of qualifiers.
976 * The CQL-to-PQF transformer's configuration file now uses
977 "index.set.name = <attributes>" instead of the old form
978 "qualifier.set.name = <attributes>". (Both forms are still
979 understood but the latter is deprecated.)
980 * CQL terms with no explicit index specified are now interpreted as
981 cql.serverChoice instead of srw.serverChoice (which of course
982 behaves exactly the same.)
986 MARC conversion can now generate ISO2709 output in another
987 character set. yaz-marcdump uses this facility if you invoke it
990 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
991 functions from there can be used from C++.
995 Frontend server now transfers memory from decoded packages to stream
998 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
999 references to show up.
1001 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1002 the ZOOM Abstract API. The older names for the same options are still
1003 also supported for the benefit of old applications.
1005 ZOOM-C supports "implementationId" and "implementationVersion" options
1006 to go along with "implementationName". These allow the user code to
1007 specify identification strings to be sent to servers.
1008 Add OID for the new ExtLite attribute set.
1010 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1011 as requested/supplid by Ere Maijala <ere@atp.fi>
1013 For generic frontend server, reverse the order of
1014 "toolkit-supplied / application-supplied" strings sent as implementationId,
1015 Name and Version. Also, remove the spaces around the slash. This brings
1016 the GFS in line with the behaviour of ZOOM-C on the client side.
1018 Add function ZOOM_scanset_display_term.
1020 yaz-client shows scan displayTerm if present.
1022 Utility yaz-iconv is now installed by default along with the man page
1025 Extend configure check for OpenSSL to use pkg-config where available (such
1028 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1029 server to specify uid/gid/mask for socket using the format
1030 unix:[user=uid,][group=gid,][umask=mask,]file=path
1031 If file= is omitted the existing format is assumed, e.g.
1033 in which case the mask is 0666 (rw for everybody).
1035 Major restructure of YAZ source. All source in libyaz is in src directory.
1036 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1037 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1039 Added man page for utility yaz-marcdump (used to be called marcdump).
1040 yaz-marcdump is installed by 'make install'.
1042 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1043 of incoming package failed.
1045 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1047 Change prototype of odr_perror: add const to message string.
1049 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1051 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1052 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1053 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1054 DNS lookup. There should not be any compatibility problems with this
1055 assuming that blocking=1 or 0 is used.
1057 Fix bad reference in UNIX comstack in function cs_addrstr.
1059 Fix for compilation on AIX.
1061 The generic front-end server (server/seshigh.c) now supports returning
1062 Init diagnostics to the client in User-information-field, in
1063 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1066 --- 2.0.4 2003/09/04
1068 Allow any CQL relation (not just all,any,exact,scr).
1070 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1071 that features the same UI.
1073 Implemented command update0 in YAZ client which is equivalent to
1074 update but uses old of Ext Update ASN.1.
1076 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1077 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1078 Previously no OID was used for this info.
1080 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1081 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1082 returns 'malformed search term' otherwise.
1084 SortResponse member resultCount now set to NULL in sort handler of
1087 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1090 Add three new utility functions for translating OIDs between various
1091 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1092 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1093 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1094 char *oid_to_dotstring(const int *oid, char *oidbuf);
1095 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1097 Reverted modifications for ES Update definition for z_IU0Update
1098 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1099 is back to YAZ 2.0.2.
1101 String value attributes for CCL parser.
1103 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1104 which their FirstSearch server returns in Init responses, sometimes
1105 carrying useful diagnostic information when Init fails. This has the
1106 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1107 "z39.50/oclcui.asn", where its definition is somewhat different from
1108 what OCLC document on their web-site, as required to interoperate with
1111 Support for anonymous authentication in yaz-client. Use the command
1114 * Fix the OID of the Index Data-local "admin" Extended Service from
1115 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1116 the 1000, which indicates a locally-defined OID, was a mistake.
1118 --- 2.0.3 2003/06/20
1120 Fix CCL directive @case handling so that it affects string match for
1121 both CCL keywords and qualifiers.
1123 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1124 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1125 Decoder has been updated with ASN.1 changes as listed in
1126 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1127 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1128 z_IUUpdate, remains unchanged.
1130 ZOOM_record_get may now return a record in a specific character set.
1131 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1132 "from" is the character set of record as returned by target. "to" is
1133 the character set to be returned. If omitted, "to" is UTF-8.
1135 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1137 New ODR utility, odr_getelement, which returns name of element for
1138 which encoding/decoding failed.
1140 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1141 in cases where a required element was omitted.
1143 Bug fix: some MARC8 sequences were not converted.
1145 New ZOOM option "step" which specifies number of records to be
1146 retrieved in one chunk. Used in conjunction with "start" and "count".
1148 SRW support for yaz-client. Use scheme http: to use it, e.g.
1151 yaz-client no longer does (un)intelligent character set conversions
1152 by default. Can be enabled with charset and marc_charset commands.
1154 xmalloc trace fix for 64-bit systems such as DEC alpha.
1156 Solaris 2.6 compile fix.
1158 New function, cql_strerror() translates SRW error codes, as returned
1159 by cql_transform_error(), into human-readable English strings. Used
1160 in yaz-client diagnostics when appropriate.
1162 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1163 converts it into a type-1 query which is sent to the server. This
1164 makes CQL available for use with all Z-servers, as opposed to the tiny
1165 minority that can handle CQL queries themselves.
1167 --- 2.0.2 2003/04/28
1169 New Debian package layout similar to the Redhat Package layout.
1171 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1172 and search result respectively.
1174 --- 2.0.1 2003/04/25
1176 Redhat package is now several packages: libyaz (runtime libraries),
1177 libyaz-devel (development and documentation, and yaz (utility programs).
1178 Package spec file by Morten Bøgeskov.
1180 New member 'schema' in struct bend_fetch_rr which the name of requested
1181 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1182 handler MAY set this to reflect the schema of the returned record.
1184 New member 'display_term' in struct scan_entry. GFS now sets member entries
1185 and allocates scan entries to be filled by user scan handler. In previous
1186 version, entries member was allocated by the scan handler. That still works,
1187 but the GFS will ignore member display_term - assuming it was NOT set by
1188 the handler. The fact that the GFS now allocates the entries both allows
1189 for new members and makes a scan handler easier to write.
1191 Fix CQL lex buffer overflow.
1193 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1194 SRU default recordPacking is string.
1196 SRU protocol support for frontend server.
1198 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1200 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1202 Added scan for the ZOOM shell (zoomsh).
1206 * String Identifers for Schemas (Amendment 5).
1207 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1208 Old definition for schema
1209 Odr_oid *schema; /* OPT */
1214 Z_InternationalString *uri;
1215 #define Z_Schema_oid 1
1216 #define Z_Schema_uri 2
1219 * resultCount parameter to Sort Response (Amendment 1).
1220 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1222 Support for SRW 1.0 over HTTP. This is an optional feature and
1223 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1226 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1227 on the same port. SRW SearchRetrieveRequests are mapped
1228 to bend_init,bend_search,bend_fetch,bend_close.
1230 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1232 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1233 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1235 ZOOM connections are SRW based if schem http is used for hostname
1236 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1237 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1239 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1240 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1241 distance=n, order=true/false, relation=le, prox unit=word. If
1242 n is omitted, distance 1 is used.
1244 Fixed problem with C compiler include path in wrong order.
1246 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1247 on Solaris. Patch from Ko van der Sloot.
1249 New MARC decode API. All new functions operate on a yaz_marc_t
1250 handle. The most important new functions are: yaz_marc_create,
1251 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1252 decode and destroy respectively. Decoder can produce formats
1253 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1254 include/yaz/marcdisp.h.
1256 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1257 to UTF-8, UCS-32, wchar_t or Latin-1.
1259 * Prototypes for yaz_iconv_-functions moved to separate header
1260 include/yaz/yaz-iconv.h.
1262 Make a few private functions 'static' in unix.c. This prevents
1263 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1265 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1266 are set when Init Response is received.
1268 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1269 but returns diagnostic set as well.
1271 New function yaz_strerror which is a portable wrapper for
1272 strerror/strerror_r/GetLastMessage.
1274 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1275 is returned for MARC. If type is "oai", then OAI MARC is returned.
1277 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1280 --- 1.9.2 2002/11/26
1282 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1284 Fix bad race conditions on SIGTERM and terminate gracefully in
1287 Move retrieval (data1) module to Zebra since nobody seems to be
1290 Add GRS-1 render for ZOOM using same format as yaz-client.
1292 --- 1.9.1 2002/10/05
1294 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1296 Fix broken ESpec handling in data1 module.
1298 SGML reader parses comments and makes them part of the data1 tree.
1300 Added several type casts so that YAZ compiles as C++ code.
1302 ZOOM didn't handle PDU encoding failures properly.
1304 Added more Bib-1 diagnostics (approved extensions).
1306 GNU configure: better check for iconv.
1308 More portable use of accept, getpeername. Check for socklen_t. Use
1309 int/size_t if socklen_t is not defined.
1313 PQF parser rejects bad queries - including those with extra
1314 characters in them. PQF parser used to silently ignore that.
1315 Cleaner API for PQF added, which allows you to get detailed
1316 error information for bad queries (see yaz/pquery.h).
1318 Fixed bug in ZOOM_record_get for type "database".
1320 Implemented mini iconv library supporting conversions between
1321 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1323 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1325 --- 1.8.9 2002/08/20
1327 Fixed ZOOM C record cache so that preferredRecordSyntax and
1328 elementSetName is used to check for already fetched records.
1330 --- 1.8.8 2002/08/02
1332 Added three members in bend_initrequest structure to facilitate
1333 character set negotiation.
1335 Fixed a bug in frontend server that could cause indefinite
1336 loops under rare conditions.
1338 Revised character set utilities (charneg.h) so that encoding
1339 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1341 For PQF, directive @term <type> sets term type for Scan/Search.
1342 Here <type> is general, string, numeric, null. The term type
1343 is inherited - just like @attr.
1345 New call odr_set_charset that sets character set conversion for
1346 international-strings on a ODR stream. Prototype is:
1347 int odr_set_charset(ODR o, const char *to, const char *from);
1348 The InternationalString is still represented as C string in YAZ
1349 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1350 won't). On the protocol level, you can use any encoding.
1352 Support for UNIX sockets in ZOOM.
1354 Solaris recv sometimes returns errno == ENOENT. It is treated as
1355 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1357 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1358 both client and server. Code by Morten Bøgeskov.
1360 --- 1.8.7 2002/05/22
1362 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1363 that they can be used directly from Visual Basic. You must recompile
1364 your windows APP if you're using ZOOM.
1366 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1367 Commands "lang" and "charset" sets language and character set respectively.
1368 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1369 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1371 Attributes from multiple CCL fields may be OR'ed rather than merged
1372 using directive "@field or". Fields are still merged by default -
1373 equivalent to "@field merge".
1375 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1378 Fixed bug in zget for parameter ExtendedServicesResponse.
1382 --- 1.8.6 2002/03/25
1384 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1386 Client displays USR.1:SearchResult-1 (hits per term).
1388 Additional Search Info for search in Generic Frontend Server.
1390 Fixed CCL parsing of "field=s".
1392 WIN32 installer - using the excellent NSIS software from nullsoft.
1394 Fixed CCL parsing of "field = - <number>".
1396 Added function yaz_marc_decode that decodes MARC for line mode
1397 display or XML (similar to that used by JZKit).
1399 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1400 Z39.50. But ISO/ILL was, however.
1402 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1403 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1405 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1406 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1408 --- 1.8.5 2002/02/03
1410 New YAZ client features: Command completion and new commands:
1411 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1412 Code provided by Jacob Poulsen.
1414 New call oid_trav, that visits all registered OIDs via callback.
1416 Function ZOOM_record_get now returns const char pointer rather than
1417 void pointer. It saves a lot of type casts.
1419 For YAZ client, command "auth" now allows you to set authentication
1420 in IdPass style. It is enabled when three tokens are given - order
1421 is user, group and password.
1423 Fix memory leaks in MARC record handling for ZOOM.
1425 New option for YAZ client, -k <kilobytes> that sets
1426 maximum record size. Similar to -k option for generic frontend
1427 server and yaz-ztest.
1429 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1431 Prefix query parser reports "fail" when bad attribute set is given.
1433 Fix in MARC decoder. Proximity logging. Fix for attribute set
1434 in scan handler for server. Patches by Shigeru Ishida.
1436 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1439 Configure option --with-openssl=<dir> now works when a directory is
1440 specified. Patch provided by Morten Bøgeskov.
1442 New option for YAZ client, -u <auth>, that sets authentication.
1444 ZOOM fix: error information was sometimes "missing", since error
1445 was cleared/reset too when it shouldn't.
1447 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1449 --- 1.8.4 2002/01/04
1451 Scan for ZOOM API. New object ZOOM_scanset. New functions
1452 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1453 ZOOM_scanset_destroy.
1455 New ZOOM function, ZOOM_connection_last_event, that returns type
1456 of last event (such as "receive data", "send data", "apdu received",
1459 New ZOOM option, schema, that specifies schema for retrieval.
1461 New CCL feature. Qualifiers can be aliases for one or more
1462 other qualifiers (if more than one is given, OR is used).
1464 ZOOM uses named result sets if target supports it.
1466 Two new YAZ client commands: . (dot, which sources a script of YAZ
1467 client commands), and ! (to execute shell command.). Implemented
1470 Working on Debian packages.
1472 --- 1.8.3 2001/11/19
1474 YAZ client enables named result sets only if target supports it.
1476 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1478 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1479 with key="host" to get same result.
1481 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1482 Function Z3950_resultset_record(s) returns references to records
1483 "owned" by resultset. To become owner use Z3950_record_clone.
1485 Function z_ext_record handles Extended Services. Thanks to
1488 --- 1.8.2 2001/11/12
1490 CCL Parser fix: ignore token comma when dealing with and-lists.
1492 Documentation updates for COMSTACK.
1494 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1495 Changed prototype Z3950_records. For some functions, int parameters
1496 were changed to size_t.
1498 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1501 New MARC decode/display function, marc_display_exl, which properly rejects
1502 non-ISO2709 records. YAZ client uses it.
1504 --- 1.8.1 2001/10/29
1506 Fix bug: local attribute set wasn't set correctly in PQF strings.
1510 * Old Z39.50 codecs no longer supported.
1512 Added ZOOM C binding. See http://zoom.z3950.org/
1514 Renamed states for COMSTACKs to avoid confusion with events.
1516 Implemented cs_look and proper cs_rcvconnect.
1518 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1520 Configure detects POSIX threads on OpenBSD.
1522 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1523 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1525 When error is returned from present handler, non-surrogate diagnostic
1526 is returned in present response (and fetch handler is no longer called).
1528 * Minor adjustments to pquery parser (PQF). Token characters may be
1529 escaped by using backslash (C-style).
1531 PQF parser allows string attribute values to be specified. For @attr,
1532 non-numeric characters after the equal-sign are treated as strings
1533 (e.g. @attr 9=title).
1535 CCL trunction character may be defined (@truncation in file)
1537 * function zget_ExtendedServicesRequest sets waitAction to
1538 waitIfPossible (was wait).
1540 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1543 CCL operator names may be set in field definition files (CCL_bibset).
1544 See ccl/bib1 for an example.
1546 Fixes in ASN.1 compiler for C++ compatibility.
1548 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1549 and "op_or" to avoid conflict with C++.
1551 Fixed problem with GNU readline detection on Redhat 7.0.
1553 Added step-size for Scan backend handler.
1555 Fixed bug that made the frontend server crash when no attribute
1556 set was specified for scan.
1558 Front-end server automatically switches to original working directory
1559 when installed as an NT service. Previously -w had to be specified to
1562 Added extended attributes for retrieval module (data1), so that data1
1563 records carry d1_readXML/SGML attributes. d1_read also supports
1564 null-data rules ( <tag/>)
1566 On UNIX when POSIX threads are available, a separate library libyazthread
1567 is created. Programmers should link with that library and the yaz library
1568 when using threads. The reason for the split was that some applications
1569 on Linux, such as Apache, doesn't work well when using shared objects that
1572 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1573 (or any frontend server) in SSL mode by specifying ssl: followed by
1574 address. Only tested on UNIX.
1576 Added feature for CCL module. Virtual structure s=al or s=ol generates
1577 and-list and or-list respectively instead of phrase search.
1581 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1582 log_mask_str. This was done to avoid name conflicts with other libraries
1583 (such as other PHP extensions).
1585 Added raw OID member for preferred record syntax (request_format_raw)
1586 and returned record syntax (output_format_raw) for backend fetch method.
1588 Config file yaz-config now accepts options so that it returns specific
1589 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1591 Shared library support for UNIX using GNU libtool.
1593 * Modified backend interface. Request/Response struct's replaced by
1594 one read/write C struct. For example bend_fetchrequest and
1595 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1596 Every handler - even search has to be registered in bend_init
1597 handler. This means that the YAZ library no longer refers to
1598 external functions and it makes it possible to make the whole
1599 thing a single DLL/SO.
1601 Added Segment handler for backend server.
1603 Added Zmbol/Zebra administrative functions to YAZ client.
1605 Threaded frontend server on UNIX (when POSIX Threads are available).
1606 Starting the server with option -T enables multi-threading.
1610 Added configure option --enable-comp/disable-comp to control use
1611 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1612 located in sub directory asn.
1614 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1615 in ${exec_prefix}/bin along with the other programs yaz-client and
1618 GNU automake used to maintain makefiles.
1620 Added several OID's.
1622 Changed retrieval module so that we can load records with no abstract
1623 syntax defined. Tagpaths in these records are fully composed of string
1626 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1630 On UNIX, the generated makefile now supports a proper 'make install'.
1631 The prefix can be set via GNU configure to set the install location
1632 (default is /usr/local).
1634 * YAZ programs client and ztest were renamed to yaz-client and
1635 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1636 locations, such as /usr/bin,/usr/local/bin,etc.
1638 * YAZ Header files were moved from include to include/yaz. YAZ Header
1639 files are referred to as include <yaz/log.h> rather than <log.h>.
1640 The YAZ include path (-I ..) is therefore the same as before. Programmers
1641 should update their #include statements or use -Ipath/include/yaz
1642 instead. The main motivation for doing this change is that YAZ header files
1643 can be installed in "standard" locations /usr/include,/usr/local/include
1644 without introducing conflicts, since ALL YAZ header files are stored
1645 in subdirectory yaz (under /usr/include for example).
1647 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1648 rather than project/workspace files. We switched because project files
1649 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1652 Changed name of logging function, logf, to yaz_log, to prevent name
1653 clash with some math-log functions. The YAZ header log.h defines logf
1654 to yaz_log (#define) so there should be no incompatibilities by this
1657 Added bend_start/bend_stop handlers for server. These handler are
1658 called on start/stop of server. For windows they are called whenever
1659 a service is started/stopped.
1661 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1662 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1663 in util/yc.tcl. The auto-generated C code structures are, in a few
1664 cases, incompatible with the old decoders. There are differences in the
1665 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1666 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1667 The preprocessor variable ASN_COMPILED is defined when the compiled
1668 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1669 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1670 wish to use the old encoders/decoders you can specify --disable-yc
1673 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1674 version so that it supports both new - and old version of DB Update
1676 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1677 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1678 change. The name parameter can be set to 0 in which no name is specified
1679 for the construction. The macros odr_implicit and odr_explicit sets name
1680 parameter to zero for the construction involved. New macros
1681 odr_implicit_tag and odr_explicit_tag are similar to the others,
1682 except that a name parameter is added. For programmers' that don't use
1683 ODR they probably only need to change the call to z_APDU and z_External.
1685 Added access control facility by interfacing the TCP wrapper library.
1686 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1687 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1688 name of the daemon and enables the access control as specified in
1689 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1691 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1692 den Dool <H.M.vdnDool@kub.nl>.
1694 Added reference ID parameter to most functions in server API - refer
1695 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1697 Changed name of ccl library to libccl.a (was ccl.a).
1699 Fixed bug in decoder for Explain (Category TargetInfo).
1701 Added support for GNU readline in client. Thanks to Jacob Poulsen
1702 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1704 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1705 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1706 IMPLEMENTATION! This change was made to the development version before
1707 the ZIG decided to retract the amendment. If any users MUST be
1708 compatible with the original Update definition, PLEASE CONTACT US, and
1709 we will include a separate definition corresponding to the old Update
1710 ES. Note that because of the change to the ASN.1 of the
1711 TaskPackageRecordStructure we cannot define a single structure that
1712 will support both versions.
1714 * Added const modifier to buffer parameter for some ODR/BER encoding
1715 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1716 completeWAIS, odr_dumpBER.
1718 Fixed bug in client.c which caused a crash when a scanResponse didn't
1719 contain positionOfTerm.
1721 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1722 * will cause an error in a client if a non-YAZ target sends both a
1723 * list of Scan entries and non-surrogate diagnostics.
1725 Retrieval module enhancements. Tag sets may be typed in the reference
1726 to it. From the .abs-file the "tagset" directive takes a third optional
1727 integer type for the tag set referenced. From a .tag-file the "include"
1728 directive takes a third optional type as well. The old "type" directive
1729 in the tag set itself is still recognized but acts as the default type
1732 Backend interface change. Individual Scan terms returned from bend_scan
1733 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1734 in include/backend.h.
1736 Retrieval module enhancements. Multiple tag sets and attribute sets may
1737 be specified in abstract syntax specs. Revised the error/warning for
1738 logging messages reported by the retrieval module when reading the
1741 Object Identifier system (oid_..) changed. The API is backwards
1742 compatible but the oid-routines now allocates new OID's when needed.
1743 Raw OID's may be specified in oid_getvalbyname.
1745 YAZ now uses GNU configure to generate Makefile(s).
1747 * Minor changes in some of the member names of DeleteResultSetRequest and
1748 DeleteResultSetResponse. See include/proto.h.
1750 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1751 and added member 'languages' in TargetInfo (which was missing).
1753 Changed the way attribute sets are handled in the retrieval
1754 module. These are now cached, just like the abstract syntaxes
1757 Changed YAZ so that it links with compiled ASN.1.
1759 Added Explain-schema definitions and mapping routines. The following
1760 Explain categories have been implemented: AttributeDetails,
1761 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1763 Fixed minor bug in Windows version of Server Library.
1765 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1767 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1769 Added EXTERNAL: UNIverse Resource Report (non-standard).
1771 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1772 ENUMERATED and SET OF.
1774 * Added 'const' to some of the char pointer arguments for the
1775 functions, data1_read_node, data1_getelementbytagname,
1776 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1779 Fixed bug in data1_insert_taggeddata - the last_child member of
1780 parent wasn't initialised.
1782 * Changed data1_read_record and data1_read_node so that the supplied
1783 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1784 doesn't refer to any parts of the "SGML"-buffer.
1786 Fixed bug in server library (Windows version of statserv_remove).
1788 * Changed code so that it compiles as C++. The type definition
1789 of Odr_fun which is a member of Odr_arm was changed. The result is,
1790 that an explicit typecast is needed for the fun pointer when
1791 using Odr_arm - as in:
1792 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1794 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1796 Implemented the new structured date and time definition as approved
1797 by the ZIG. Added schemaId element to the specificTag in Espec-1
1798 (also approved at the last ZIG). Thanks to RVDM.
1800 Added some Object identifiers (RVDM).
1802 Changed the Update Extended Service (RVDM).
1804 Added command "refid" to client which specifies referenceId for
1805 the following requests.
1807 Implemented extended service handling for server. See ztest.c
1808 for an example as well as backend.h. New handlers are registerd
1809 in the Init handler.
1811 * Changed interface for sort in server.
1813 Added new members to statserv_options_block. It allows a server
1814 to read options from another source than just the command line. Thanks
1815 to Charles Woodfield.
1817 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1818 renamed to zboolean. Some C++ compilers complained about the name.
1820 Minor changes to gils.abs. Added index 's' (sort) on title
1821 and date/time-last-modified.
1823 --- 1.4pl2 1998/1/30
1825 Fixed bug in server library regarding inetd mode (-i). This bug
1826 was introduced by release 1.4.
1828 --- 1.4pl1 1998/1/29
1830 Added sort facility in client and backend server interface.
1832 Fixed problem with dependencies in Makefile(s).
1834 Fixed bugs for encoders/decoders of extended services and
1837 Implemented sub-tree feature for schemas. Sub-trees are
1838 referenced in *.abs-files. See explain.abs for an example
1839 of the use of this feature.
1841 Modified bib1.att; local attributes for ANY didn't include
1842 ANY itself (only affects use of the retrieval module).
1844 Fixed bug in plain SGML reader in function data1_read_node:
1845 tags with prefix "var" was incorrectly interpreted as variants.
1847 Added feature "sub-schemas" to enable references to - and definitions
1848 of - group of elements.
1850 * Removed member parent from type data1_element (in data1.h).
1852 Implemented function odr_nullval() that returns the value of
1855 * Removed member num_children from data1_node (in data1.h).
1857 Made NT service interface part of the server library. The
1858 function statserv_main uses the NT service when required and
1859 calls the statserv_start / statserv_close routines.
1861 Routine zget_SearchRequest and zget_PresentRequest fills
1862 resultSetName/Id member with "default" instead of "Default".
1864 Fixed memory leak in server. Request queue member wasn't freed.
1866 Fixed nmem_exit so that memory is freed.
1870 Revised the CCL parser utility to be thread safe.
1872 Added function, oid_ent_to_oid, to replace the function
1873 oid_getoidbyent, which is not thread safe.
1875 * Added nmem_init and nmem_exit to initialize and release
1876 NMEM resources. Function nmem_init should be called once in the
1877 initial thread before NMEM/ODR is used. statserv.c and client.c
1878 have been changed accordingly. The change was necessary to make
1879 NMEM thread safe. The NMEM memory pool is shared amongst threads
1880 in a process. Unix-based applications will still work fine without
1883 Added NT Services interface for the the Z39.50 (statserv) Server.
1884 Refer to the ztest.c source on the usage.
1886 Windows 95/NT port using MSVC5.0. Project files are included in the
1889 * Defined new 'global' handle for the retrieval (data1) system. The
1890 new handled, data1_handle, describes the state of the data1 system.
1891 This handle is passed as first argument to virtually all
1892 data1 related routines. The functions data1_create and data1_destroy
1893 creates and destroys a data1 handle respectively.
1895 Added ODR encode stream member to all backend request structures
1896 init, search, scan etc. This stream should be used to allocate all
1897 memory used for the response when thread safe operation is needed.
1899 Changed the comstack utility, cs_addstr, to be thread safe. The
1900 returned hostname string returned by the function is now part the
1903 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1904 function. The cs_straddr takes a COMSTACK handle as argument, so this
1905 function must be used after cs_create and before bind/connect.
1906 This function is thread safe.
1908 Moved test server to 'ztest' directory - generic server code still
1909 in 'server' directory.
1911 Made prefix query (pquery.c) utility thread safe.
1913 Added new function modifier YAZ_EXPORT to 'export' public DLL
1914 functions when using windows (see include/yconfig.h).
1916 Added definitions to the OID database (util/oid.c) (RVDM).
1918 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1920 Added call to ccl_rpn_delete in client program.
1922 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1923 release of RPN structure.
1925 Added support for C++, headers uses extern "C" for public definitions.
1926 With input from RVDM.
1928 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1929 Thanks to Ronald van der Meer (RVDM).
1931 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1933 Added support for private extensions to the OID database
1934 (oid_setprivateoids()). Thanks to RVDM.
1936 Added optional, physical ANY (key replication)
1938 Fixed null-reference problem in GRS-1 output filter.
1940 Proximity operator added to Prefix Query Format (PQF).
1942 In test client command "base" accepts multiple databases.
1944 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1948 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1950 Smallish bug-fixes in the new encoders/decoders (explain).
1952 Bug fixed in DeleteRequest.
1954 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1956 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1958 Added SOIF syntax (using private OID for now) to retrieval module and client.
1960 Added Update extended service.
1962 Added SearchResult-1 additional info structure.
1964 Added optional CCL (ISO8777) interpreter as separate module. Available
1967 --- 1.2 1996/6/10 (1st anniversary release)
1969 Added Summary record syntax. Lightly tested.
1971 Added OPAC record syntax. Untested.
1973 Added ResourceReport service encoders/decoders. Untested.
1975 Fixed bug in z_Unit - wrong tagging on unitSystem.
1977 Fixed bug in the DiagRecs decoder.
1979 Added options for max PDU size and session timeout to frontend-server.
1981 Added documentation of query-language parsers and other supporting utilities.
1983 [frontend-server] Added Attribute set to the bend_scanrequest API.
1985 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1986 surrogate diagnostics were generated.
1988 [retrieval] Allow multiple local values for attribute.
1990 [retrieval] Allow multiple attributes per element in .abs files. index type.
1992 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1994 --- 1.1pl2 1996/4/10
1996 Minor changes, mostly specific to Zebra's requirements (retrieval)
2000 Repaired bug in frontend server when running multiple listening
2001 endpoints in dynamic mode.
2003 z_External() now won't break if a known, ASN.1 value comes encapsulated
2004 in an octet-string. The value will pass through unmodified in an Odr_oct.
2006 Added a bit of code to the demo client to decode & display
2007 ASN.1-structured records represented in the octet-aligned branch of
2008 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2010 Added z_ext_getentbyref() to the ASN module. Doc updated.
2012 * Completed the SCAN definition in the ASN module. This may break SCAN
2013 code based on older YAZ-versions at compile-time. The fix is easy -
2016 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2017 under the SCAN definition. Remember to initialize this, server-people.
2019 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2020 that this does not extend to ODR and ASN.
2022 Comstack allows insertion of established socket (primarily for
2023 inetd-operation of servers). Doc updated.
2025 Front-end server can now start from the inetd in TCP mode. Doc
2028 --- 1.0pl4 1996/1/24
2032 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2033 the rank and record number.
2035 Adjustments to the frontend server.
2037 Fixed diagnostic BER dumper. It ignored the file argument.
2041 Various changes to retrieval module.
2043 Changed the union discriminators of the protocol files from enums to
2044 ints paired with #defines.
2046 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2049 *Changed operator in the RPN structure to 'roperator', again to avoid a
2052 Fixed problems in Explain decoders/encoders.
2054 --- 1.0pl2 1995/12/6
2056 Memory bug in log module fixed.
2058 --- 1.0pl1 1995/12/5
2060 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2062 Bug in Explain DatabaseInfo module fixed.
2064 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2068 The shift to v1.0 signals that we now consider the *core* functionality
2069 of YAZ reasonably stable (the core being more or less equivalent to
2070 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2071 tested (Explain not at all - though that will happen soonish).
2073 Minor changes to code to support Windows port.
2075 Various minor changes after we're getting to use GRS-1 & co. more.
2077 Added Espec-1 format.
2079 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2080 of the protocol and it cannot be selected when encoding (maps into 'string'
2081 when decoding). Needed to talk to some servers.
2083 Demo client can request simple element set names.
2085 Added Diagnostic Format encoders/decoders.
2087 Added simple Close handling to frontend server (no hooks for resource
2088 reporting yet), and demonstration client.
2090 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2092 --- 1.0b3 1995/08/24
2094 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2095 handled incorrectly when records were requested in the searchResponse. This
2096 will only affect you if you use the frontend-server.
2098 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2099 Test-client will ask for and print GRS1. Ztest will return dummy records
2102 Added Explain encoders/decoders to the service-level API. Untested.
2104 Added Extended Services: Item Order encoders and decoders to the Service-
2105 level API. Untested. We could use a recent copy of the pertinent bits
2106 of the ILL protocol to add those bits.
2108 Added diagnostic format 1 encoders/decoders to the service-level API.
2111 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2112 odr_cons.c, which causes a more correct output.
2114 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2115 was always set to 0 when no records were requested in the searchRequest.
2117 * Added better external-handling. This shouldn't harm old code that
2118 *encodes* externals. It can break code that looks for a
2119 'single-ASN1-type' representation, since those types that are known
2120 are now decoded immediately. Look at the SUTRS sample code in
2121 seshigh.c and client.c. Documentation updated.
2123 Handling of structured records in bend_fetchresponse. Length -1 marks
2124 structured record, type is deduced from format field.
2126 --- 1.0b2 1995/06/27
2127 Fairly quick maintenance release to add SUTRS support.
2129 Fixed handling of SUTRS records in the demonstration client.
2131 * Added format field to the bend_fetchrequest and bend_fetchresponce
2132 structures of the backend API (frontend server). When the record is
2133 returned, the value of the format field is mapped to an OID. The
2134 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2135 of the record. The special value VAL_NONE in the bend_request means
2136 that no specific format was requested by the client. Documentation
2137 updated accordingly. Test server (ztest) will return a fixed dummy
2138 SUTRS record if your client requests SUTRS.
2140 Documentation updated accordingly.
2142 You can now set external libraries and RANLIB support in the top-level
2146 First public release.
