3 Added CCL utility to remove terms (stop words) from resulting RPN
4 tree. This is handled by functions with prefix ccl_stop_words_ .
6 New ZOOM C option, "rpnCharset", which allows client-side conversion of
9 Clean-up the CCL API. Moved some internal structures from ccl.h to
10 private header cclp.h. Changed ccl_parser_create so that a Bibset must
11 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
12 This is replaced by ccl_parser_find_str which takes a string instead.
14 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
15 libyaz.la is the core of YAZ except the generic frontend server and
16 does not depend on POSIX threads anymore. libyaz_server.la is the
17 generic frontend server facilities and uses POSIX thread functionality
18 if available. The libyaz.la no longer depends on POSIX threads because
19 the number of global structures is limited. NMEM no longer re-uses blocks
20 between threads ; it simply free's memory immediately but allocates in
21 "large" chunks as usual. We don't expect any performance penalties
22 because of this. The yaz_log system is still using a global log_level so
23 caution must be taken when modifying it with yaz_log_init_.. +
24 yaz_log_mask_str. This, however, should not cause any trouble because
25 these functions are called during initialization of application code
26 anyway. `yaz-config --libs server` returns libs for server applications;
27 `yaz-config --libs` returns libs for non-server applications.
29 New OID database - with public definitions in oid_db.h. Removed old OID
30 database including the head oid.h and definitions such as enum oid_value
31 and struct oident. The new OID database uses the same string names as
32 before but the 'protocol' is gone. There are now only two representations
33 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
34 converts from string to OID; functions with prefix yaz_oid_to_string
35 converts the other way.
37 Change to emit_term() in CQL-to-PQF query translation: when a term has
38 the /regexp relation modifier, do not process it for leading and
39 trailing "^" and "*", which have quite different meanings in regular
42 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
43 write handlers no longer carries a 'last' parameter. This will make
44 yaz_iconv flush "less" characters. A flush is performed by call to
45 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
47 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
48 removed, because function yaz_query_to_wrbuf does the same.
50 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
51 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
53 Deprecated MARC utility functions removed.
55 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
58 Branch split: YAZ_2_1_55_branch
62 Fix to ZOOM-C so that transparent reconnection is properly handled on
63 connections that are in asynchronous mode.
65 Fixed compilation on OpenBSD 4.0.
67 Large strings in GRS-1 records are now properly displayed in yaz-client.
69 Added character conversion support for "advancegreek"; based on patch from
72 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
73 sequence is met. Before the error was not set so it would be unknown.
75 Adjust yaz-marcdump MARC reader so that it skips until record separator
80 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
81 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
82 fd_set structure used as a bitmask for the FDs to be selected on.
84 Using ACX_PTHREAD macro to check for POSIX threads.
86 Fixed have-vsnprintf check.
90 Fixes for configure on BSD. Bug #900.
92 Added snprintf/vsnprintf wrappers for systems that don't have
93 limits (heavens forbid).
95 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
96 created before all previous tasks were completed and removed from the
97 task queue, the new task could be removed by a mistake.
99 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
101 Implemented pass-through CQL-to-PQF conversions. Bug #861.
103 Fixed bug #832: Problem with MARC/charset in yaz-client.
105 Fixed bug #668: save command line history for yaz-client.
107 Fixed bug #830: pkg-config support.
109 --- 2.1.48 2007/01/23
111 Extended ZOOM result set options with two options that may be read by
112 a client: resultSetStatus and presentStatus with values as specified for
114 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
116 Fixed bug #827: Using SSL fails on Debian etch.
118 Fixed bug #826: Weird looking chars for set of MARC records.
120 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
121 that is treated as an ItemOrder with itemRequest being an XML document
122 external. The value of "doc" is the content.
124 Extended the GFS search facility. New member of bend_search_rr
125 'estimated_hit_count' signals that hits is known to be an estmate
126 (higher or lower than real hit count). New member 'partial_resultset'
127 signals that the search was partial (hit count is lower or equal than
128 real hit count). For Z39.50, the information is stored in resultSetStatus
129 member of SearchResponse APDU. For SRU, the information is signalled
130 via SRU diagnostic 59: "Result set created with valid partial results
133 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
135 --- 2.1.46 2007/01/13
137 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
139 Added ZOOM_connection_peek_event.
141 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
142 the following new functions:
143 ZOOM_event_nonblock, ZOOM_connection_process,
144 ZOOM_connection_get_{socket,mask,timeout},
145 ZOOM_connection_fire_event_{timeout,socket}.
146 The existing blocking event handler, ZOOM_event, is a wrapper for the
147 + blocking ZOOM_event_sys_{poll,select}.
149 Implemented function ccl_xml_config which parses XML version of CCL
150 configuration (bug #798).
152 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
154 Added timings utility (yaz/timing.h)
156 --- 2.1.44 2007/01/03
158 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
161 Fixed bug #779: Rotation of apdu.log fails.
163 Fixed for character set conversions:
164 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
165 Honor G1 set in MARC-8 decoding.
167 --- 2.1.42 2006/12/17
169 Fixed bug #775: char conversion does not handle Alternative UTF-8
172 Implemented function yaz_marc_read_line which parses MARC line format
173 records. There is a wealth of formats out there. So far, this function
174 reads line records produced by yaz_marc_write_line.
176 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
177 more generic and easier to remember(!) options: -i format and -o format
178 which specifies input format and output format respectively - where
179 format is one of "marc", "marcxml", "line", "marcxchange".
181 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
182 does not print anything except warnings for records.
184 For yaz-marcdump, added support for MARC split into files (-s) with a given
187 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
188 spec, at http://www.loc.gov/standards/sru/record-update/
189 This has changed the binary layout of the following structs:
190 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
191 bend_update_rr . Patch by Ko van der Sloot.
193 Added GFS utility function bend_assoc_is_alive which returns 1 if
194 association is still alive (client is connected); 0 otherwise (client
195 closed connection). This allows busy servers to stop working for
198 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
199 been a separate piece of software. This version of ziffy has been modified
200 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
202 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
204 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
205 Client code may now interrogate options such as "init_opt_sort" to
206 find out whether the server claims to support various options.
208 --- 2.1.40 2006/11/27
210 Added utilities yaz_{set,get}_esn to set/get element set name from
213 Removed the build of libyazthread.la. The libyaz.so is the threaded version
214 of YAZ and has been so since YAZ 2.1.10.
216 Implemented ZOOM_record_error which returns error information for
217 record (surrogate diagnostic).
219 --- 2.1.38 2006/10/31
221 Updates for SRU Update by Ko van der Sloot:
222 1. Changed name from "operation" to "action"
223 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
224 versions in the code, marked as 'backward compatible'.
225 3. Added diagnostics for SRU Update.
227 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
229 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
231 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
233 For GFS, fixed problem with SRU diagnostic 'First record position out of
234 range' being issued for 0 hits.
236 zoomtst10 part of Windows Build.
238 --- 2.1.36 2006/10/13
240 Implemented yaz_filepath_comp which splits a path into file path
241 components (required by Zebra 2.0.3+).
243 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
244 BSD inspired license until now so this should not have any real impact on
245 anybody. See http://www.opensource.org/licenses/bsd-license.php
247 Fixed bug #687: Missing log lines.
249 Fixed bug #678: CQL to PQF translation does not preserve double-quote
252 Fixed bug #689: SRU diagnostics to be added.
254 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
255 whether a connection is idle (no more work do do).
257 --- 2.1.34 2006/10/04
259 Change type of optval from long to int for invocation of setsockopt with
260 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
262 Added support for specifying the max log file size for the Generic
263 Frontend Server. The size is given with option -r.
265 --- 2.1.32 2006/09/21
267 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
269 --- 2.1.30 2006/09/17
271 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
274 Fixed bug in Generic Frontend Server that could cause a server to stop
275 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
277 For the generic frontend server, the maximum record size is used as maximum
278 size of incoming packages (SRU + Z39.50). The value until was previously
279 only used in Z39.50 Init negotiation and, later, in a session controlled
280 sizes of records returned. This is controlled using -k option. It can be
281 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
283 --- 2.1.28 2006/09/04
285 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
288 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
290 New option for yaz-marcdump -lpos=value which allows setting a portion
291 of MARC header to a certain value.
293 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
295 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
296 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
298 --- 2.1.26 2006/08/15
300 Fixed problem with SRU mode type (soap, get, post) for yaz-client
303 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
305 --- 2.1.24 2006/08/08
307 Fixed MARC ISO2709 encoding routines to deal with character set
310 Minor changes to GFS logging. Database included in search request log
313 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
314 cached/multiple records.
316 Shared libraries are built by default on Unix+configure.
318 Changed cql2pqf transformation to use a different evaluation order. The
319 new order is: always, relation, structure, position, truncation, index
320 and relationModifier. Old order was: always, relation, relationModifier,
321 structure, index, position, truncation. Note that the the latter ones
322 override former ones for identical attributes.. The new scheme means that
323 it is possible to override any existing attribute with a relationModifier.
324 And also that it is possible to override everything for the index rule
325 (except the ones listed in relationModifier). No order is perfect but this
326 one, we believe, covers more real cases.. The "always" should have been
327 called "default", since the attributes there can be overridden with all
330 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
331 compilation phase, but also for yaz-config --cflags output. This allows
332 us to have public headers with Libxml2 stuff in them . It should also,
333 eventually, make Libxml2 checks redundant in packages using YAZ, such
336 --- 2.1.22 2006/06/15
338 Changed SRU update structure bend_update_rr so that SRU diagnostics are
339 stored in uri, message and details.. Previously diagnostics were stored
340 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
341 compatibility.. but he's probably the only one affected, so.
343 Added support for CCL, compiled on the client side, in ZOOM-C. This
344 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
345 input; the resulting query objects can be used for for searching with
346 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
348 YAZ' configure searches for OpenSSL by default.
350 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
351 SL_CTX_use_certificate_file. See
352 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
353 for more info. Thanks to Ko van der Sloot.
355 --- 2.1.20 2006/06/02
357 Bug #600: SRU GET, POST support for yaz-client. Introduced
358 command 'sru' which selects method SOAP/GET/POST.
360 Allow missingValueAction to be specified for the sortspec string -
361 function yaz_sort_spec. By default, the missing value action is null.
362 Use ! to specify "abort". Use = followed by stringvalue to specify default
365 Ensured that Present-handler (if defined) is called in GFS before any call to
366 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
367 searchRetrieve requests.
369 Documentation for YAZ is now based on the Docbook XML/XSLT using
370 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
371 is no longer depending on jade/openjade or docbook-to-man scripts.
372 PDF is no longer part of the distribution - but can optionally be
373 made using DSSSL/jadetex or FOP.
375 Added retrieval handling support in Generic Frontend Server to support
376 conversion between MARC/XML as well as XSLTtransforms. See
377 etc/yazgfs.xml for an example.
379 Added Authentication support to Generic Frontend Server in SRU
380 mode. Authentication using HTTP Basic is supported, as is the use
381 of 'x-username' and 'x-password' parameters in the request itself.
383 Added support for a new character set MARC8s identical to MARC8 except
384 that it converts combined characters to single Unicode characters in the
385 Latin-1 range (when possible).
387 --- 2.1.18 2006/04/24
389 ASN.1 compiler 0.4: generates brief Doxygen file header for
390 generated .h/.c files.
392 Utility yaz_iconv now supports conversion to MARC-8.
394 New facilities for the MARC module. The reading - and writing of
395 content are separate methods for the yaz_marc_t handle. The following
396 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
397 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
398 format). Write functions have prefix yaz_marc_write_.. The existing
399 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
400 available. Removed support for OAI-MARC and simplexml (not the
401 simplexml from PHP5).
403 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
404 to be returned for this connection.
406 --- 2.1.16 2006/03/31
408 Allow multiple languages and charsets to be specified with
409 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
410 negcharset iso-8859-1,utf-8
412 Translation of proximity nodes from CQL into PQF now works.
414 Moved to automake 1.8, 1.9.
416 Added function yaz_log_set_handler which allows a log handler to be
417 installed. This handler will be called for all log messages. Output
418 to file is also produced; but that can be disabled by passing NULL
419 fname to yaz_log_init_file.
421 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
423 For SRW (including GFS), accept application/soap+xml as content-type
426 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
427 produces NO stylesheet reference even if a default stylesheet is specified
430 --- 2.1.14 2006/03/14
432 Updated Windows package to include yazd.dll + yazd.lib for the
433 Development component.
435 If the environment variable YAZ_LOG is set, then it is used as a
436 string indicating the default level of logging to use if not
437 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
438 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
439 used as before. So, for example, to omit warnings from YAZ logging,
442 cql_transform() now map structure and other attributes before indexes,
443 so that index-specific structures and other attributes can override
444 defaults. So now a combination of mapping specifications such as:
446 index.dc.date = 1=date-modified 4=5
447 does the right thing.
449 cql_transform() now also respects the "always" mapping specification,
450 which establishes an initial set of attributes to be used for all
451 terms except where overridden by more specific attributes associated
452 with the index, relation or modifier.
454 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
455 which mode to use; one of "post", "get" or "soap" (SRW, default).
457 Fixes for yaz_iconv routines: changed trie-based character set conversions
458 to use only non-negative values for bit fields due to Sun's C compiler not
459 supporting negative values.
461 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
462 sequences where not read correctly. Fix by Rustam Usmanov.
464 Updated win/makefile to use options, settings which makes things
465 compile with VS C 2005.
467 --- 2.1.12 2006/02/01
469 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
471 In ZOOM socket code, use select instead of poll on MacOSX.
473 ZOOM-C now support client-side compilation of CQL into RPN that is
474 sent to the server, enabling CQL to be used against all Z39.50
475 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
476 ZOOM_query object, and submit it using ZOOM_connection_search().
477 The CQL-to-RPN translation uses a configuration file, the name of
478 which must be specified in the Connection's "cqlfile" option.
480 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
481 function, which takes as its start-term parameter a ZOOM_query object
482 (which may have had either CQL or RPN set into it).
485 --- 2.1.10 2005/11/29
487 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
488 GFS to support this as well. Backend handler, bend_srw_update, does the
489 update work. Code contributed by Ko van der Sloot.
491 Allow retrieval of Search Result-1 information in ZOOM by the use of
492 options that are attached to a result set. ZOOM documentation updated
495 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
496 UTF-8 conversion. Patch by Raj Patel.
498 Added option -m to GFS to control formatting of timestamps in log file.
500 Added 'exit' as synonym for 'quit' in yaz-client
502 Added support for specifying SRW resultSetId + resultSetIdleTime in a
503 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
504 for the new members. Patch by Ko van der Sloot.
506 Added support for SRU POST. It is supported for content-type
507 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
509 Do not build the separate Multi-threaded (MT) library libyazthread.la.
510 Instead make the library libyaz.la multi-threaded. Threading as a whole
511 can still be disabled by configure option --disable-threads. Previosly,
512 with older GLIBCs there were problems with MT libs under Apache. This
513 has now been fixed a long time ago.
515 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
518 CQL module modified to be case insensitive for relations/indexes/operations.
520 Fixed bug in CQL transform code: incorrect value relationModifieder
523 Added 'show all' command for yaz-client which retrieves all results
526 Added new yaz-client, xmles, which takes a (private) OID and
527 a document to be sent as an extended service request.
529 Describe new yaz-client commands wait_response and set_auto_wait.
531 Increase TCP/IP listener backlog from 3 (which I am guessing was
532 copied from the SunOS manual entry way back when) so SOMAXCONN, so
533 that the socket will queue as many incoming connections as it's able
534 to handle ongoing connections. In other words, it will never now
535 refuse a connection that it would be able to handle merely because
536 it's not got around to accepting() enough of the pending connections
537 yet. This is the behaviour anyway under Linux, where the listen()
538 argument is ignored; but not under BSD and on systems such as
539 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
540 YAZ-based servers should now be uniform across operating systems in
543 yaz-marcdump uses 64-bit file access on some systems. This is enabled
544 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
545 This allows yaz-marcdump to read large MARC batches (>2 GB).
547 Modified all YAZ source files - except the source which is auto-generated
548 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
551 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
552 corresponding to the existing *_setl() function. These allow option
553 values containing arbitrary valuues.
555 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
556 ZOOM_resultset_sort() in new applications. Its behaviour is identical
557 except that it returns an indicator of whether or not the sort
558 criterion was accepted (0 for OK, -1 for invalid).
562 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
563 MARC output rather than returning "new" buffer.
565 yaz-client warns about unknown init options.
567 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
571 Added support for SRW sort in Generic Frontend Server. Patch
572 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
573 sortKeys - or NULL if none is provided.
575 Fixed bug #307: It was impossible to specify indefinite/no timeout
576 for ZOOM_event. Special timeout value -1 now means indefinite timeout
579 Added support for multiple languages and charsets to be specified in
580 ZOOM. Each charset/language is separated by a blank. If negotiation is
581 in effect in init-response, Option
582 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
583 Code based on patch by Vasiliy Osadchuk.
585 Fixed bug #306: infinite recursion that occurred when calling
586 yaz_log_level_init as the first call (before other log level or
589 Fixed bug in scan handling in front end server: if preferred-Position-In-
590 Response was non-present, a NULL pointer referece was performed.
594 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
595 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
596 now defined for all those error codes. So instead of putting 109 in
597 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
598 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
600 Modified the yaz-marcdump utility to skip garbage bytes between MARC
603 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
605 Program yaz-client now exits and produces an error message if multiple
606 Z39.50 servers are specified on the command line (none or one allowed
609 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
614 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
616 Fixed bug #272: Preserve spacing for CCL terms.
620 Added support for virtual hosts and multiple backend servers for
621 the YAZ frontend server. The configution is XML based and
622 support specificition of CQL to RPN mappings and explain information.
623 See section "Virtual Hosts" in the YAZ manual.
625 Extended OPAC display utility. OPAC display utility renders
626 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
627 to supplement yaz_marc_decode_wrbuf.
629 Fixed a bug in MARC decoder that could caused it to crash for some
630 invalid MARC records. More diagnostics and warnings where added in
631 XML output (warnings, etc are stored in comments).
633 --- 2.0.34 2005/02/08
635 Fixes for UNIX domain sockets. Bug #261.
637 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
639 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
640 Added yaz_marc_subfield_str which defines subfield lead string which is
641 used in YAZ_MARC_LINE format. Default string is blank+$. Added
642 yaz_marc_endline_str which defines end of fields string used in
643 YAZ_MARC_LINE format. Default string is newline.
645 Experimental support for MarcXChange. This format can be produced
646 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
647 http://www.bs.dk/standards/MarcXchange.xsd
649 Added yaz-client commands scansize that sets maximum number of
650 entries to be returned by scan.
652 --- 2.0.32 2005/01/11
654 Added support for SRW scan in yaz-client and Generic Frontend Server.
656 * Added whereInList member to SRW Scan Term.
658 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
660 Fixed NMEM system to return aligned blocks on the smallest boundaries
661 that are suitably aligned for all possible types on the particular
662 architecture YAZ is being built for.
664 --- 2.0.30 2005/01/04
666 Fixed numerious warnings that was issued with newer versions of GCC.
668 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
669 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
672 Make YAZ Generic Frontend Server slightly faster.
674 Enhance (and reduce) logging for Generic Frontend Server.
676 Revert YAZ log system so that it flushes every write operation
677 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
679 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
680 instead of LOG_, due to name clash with syslog(3). LOG_ are still
681 present. New applications should define YAZ_USE_NEW_LOG=1 - this
682 will effectively disable old definitions.
684 --- 2.0.28 2004/11/09
686 Added yaz_log_time_format which specifies log format using
689 Added yaz_log_module_level which returns mask for a module. Value
690 is non-zero mask a if module is enabled; zero if disabled.
692 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
693 in include/yaz/cql.h.
695 Fixed bug #176: Dont throw diagnostics on empty SRU args.
697 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
699 Fixed bug #172: RPM builds does not enable SSL.
701 Doxyfile.in part of dist. Doxyfile generated by configure.
703 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
704 are given and the corresponding component does not exist.
706 Extend CCL documentation in YAZ reference. Describe r=r.
708 --- 2.0.26 2004/10/01
710 Fixed MARC->MARCXML conversion to properly deal with
711 fields, subfields, indicators having non-ASCII characters.
713 Fixed MARC->MARCXML conversion so that ASCII control characters
714 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
717 Added YAZ GFS support for conversion from Z39.50 surrogate
718 diagnostics to SRW surrogate diagnostics.
720 Bug fix: YAZ GFS did not return schema in explainResponse.
722 --- 2.0.25 2004/09/30
724 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
725 now converts recordSchema to elementSetName as well as schema URI.
727 Fixed bug in COMSTACK that prevented HTTP request packages from being
730 --- 2.0.24 2004/09/29
732 Added CCL facility r=r "range" which is similar to r=o "ordered" but
733 does not require white-space before and after the dash in a range, e.g.
734 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
737 Fixed a few AC_TRY_LINK configure tests that did not operate properly
738 due to new GCC removing "redundant" code.
740 Added yaz-client commands scanpos and scanstep that sets preferred
741 position and step-size for scan.
743 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
745 Added CCL utility ccl_qual_buf which parses one or more CCL
746 spec lines in a buffer.
748 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
749 of name and value - ignoring empty lines and comments.
751 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
753 Added odr_get_element_path which returns current element path for an
754 ODR handle. This utility is useful in error handling or user-defined
757 Added ODR_PRINT utility odr_set_stream which is is a more generic
758 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
759 to a write function and pointer to close function. The close function - if
760 non-NULL - will be called during odr_destroy.
762 Fixed bug in CCL parser where truncation char was not removed from
763 right side when truncation=both was in effect.
765 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
768 --- 2.0.23 2004/08/11
770 Fix buffer overrun in CQL parser when dealing with proximity (%).
772 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
773 to UTF-8/UCS conversion is now only based on codetables.xml.
775 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
777 --- 2.0.22 2004/08/06
779 Add support for more "commit changes" in ZOOM (uses Extended Services).
781 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
784 Yet another small fix for configure of SSL.
786 --- 2.0.21 2004/05/14
788 Fix SSL libs for configure when --with-openssl=DIR is given.
790 --- 2.0.20 2004/05/10
792 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
794 SSL comstack now uses yaz.pem certificate file on server side
795 by default. Certificate filename can be configured by calling
796 comstack function cs_set_ssl_certificate_file before cs_bind is used.
798 Fix bug regarding multiple calls to ZOOM_connection_connect.
800 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
802 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
803 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
805 ZOOM now allows inspection of X509 peer certificate for verification.
806 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
808 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
809 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
810 as "modular" but it simplifies things.
812 Added cs_get_peer_certificate to that returns peer X509 PEM.
814 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
815 NULL if SSL is unavailable.
817 Documentation about MARC decoding tools.
819 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
821 --- 2.0.19 2004/03/30
823 Rename CHANGELOG to NEWS to follow GNU style packing.
825 Fix bug with missing initialization of member in init_diagnostics.
826 This bug affects threaded version of GFS server.
828 --- 2.0.18 2004/03/20
830 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
833 Ensure zlib.dll is packed with Windows install.
835 --- 2.0.17 2004/03/17
837 Fix encoding of xsd:string to use text instead of CDATA.
839 Fix endless loop in CQL parser with unbalanced ".
841 Use a more compact way to store MARC-8 conversion tables.
843 --- 2.0.16 2004/03/16 Debian only
845 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
848 Update CQL parser to use new CQL 1.1 modifiers for booleans and
853 --- 2.0.15 2004/03/01
855 Another fix for decoding of XML packed records.
857 --- 2.0.14 2004/02/25
859 Fixes for Chunked encoding. White space not ignored after length spec.
861 Update NS and use default NS for SRW diagnostic elements.
863 --- 2.0.13 2004/02/23
865 Implement ZOOM_resultset_cache_reset which resets record cache.
867 Implement ZOOM_resultset_sort which sorts a result set.
869 Implement chunked HTTP transfer.
871 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
873 --- 2.0.12 2004/02/16
875 Added member 'schema' to bend_explain_rr structure so that backend
876 can specify explain record identifier. Defaults to Zeerex 2.0.
878 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
880 --- 2.0.11 2004/02/16
882 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
885 Added init command for yaz-client which sends "extra" init request.
887 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
888 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
890 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
892 Make ZOOM error code for "invalid query".
894 Fixed compilation for SSL which wasn't properly enabled for all platforms.
896 --- 2.0.10 2004/02/05
898 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
901 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
903 Added option -p <file> to make Generic Frontend Server to write PID file.
905 Added option -D to put Generic Frontend Server in background on its own.
907 Make ZOOM C recognize option "password". If unset, "pass" is used
908 (for backwards compatibility).
910 Fixed a bug in Generic Frontend Server that could make it crash if a
911 client sets characterSetNegotation bit, but didn't pass negotiation stuff
914 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
915 Must be issued before open, in order to be in effect.
917 --- 2.0.9-6 2004/01/12 Debian/Windows
919 Make the SRU server more picky WRT unknown params, etc.
921 Bug fix: ZOOM scan response didn't return displayTerm - when present.
923 New YAZ client command, options, that sets Z39.50 options.
925 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
926 options from a string of tokens (one token for each option bit).
928 Update SRW diagnostic code messages.
930 --- 2.0.9-5 2004/01/07 Debian/Windows
932 Handle user defined stylesheet for SRW/SRU.
934 --- 2.0.9-4 2004/01/06 Debian/Windows
936 Fix bug in decoding of Content-Length.
938 --- 2.0.9-3 2004/01/06 Debian/Windows
940 Fix a bug with decoding of XML packed records.
942 --- 2.0.9-2 2004/01/05 Debian only
944 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
946 Fix bug in SRW/SRU diagnostics decoding.
950 Fixed bug in Generic Frontend Server which could drop records exceeding
951 preferred message size. Reported and fixed by Irina Dijour.
953 Fixed calculation of package size for structured records in Generic
954 Frontend Server. Reported and fixed by Irina Dijour.
956 Fixed namespace for SRW/SRU diagnostics.
958 Fixed SEGV in yaz-client that occured for HTTP connection errors.
962 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
963 this version is incompatible with version 1.0 and older YAZ SRW/SRU
966 CQL changes to reflect recent changes to the specification:
967 * Documentation talks about context sets instead of index sets.
968 * Documentation talks about indexes instead of qualifiers.
969 * The CQL-to-PQF transformer's configuration file now uses
970 "index.set.name = <attributes>" instead of the old form
971 "qualifier.set.name = <attributes>". (Both forms are still
972 understood but the latter is deprecated.)
973 * CQL terms with no explicit index specified are now interpreted as
974 cql.serverChoice instead of srw.serverChoice (which of course
975 behaves exactly the same.)
979 MARC conversion can now generate ISO2709 output in another
980 character set. yaz-marcdump uses this facility if you invoke it
983 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
984 functions from there can be used from C++.
988 Frontend server now transfers memory from decoded packages to stream
991 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
992 references to show up.
994 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
995 the ZOOM Abstract API. The older names for the same options are still
996 also supported for the benefit of old applications.
998 ZOOM-C supports "implementationId" and "implementationVersion" options
999 to go along with "implementationName". These allow the user code to
1000 specify identification strings to be sent to servers.
1001 Add OID for the new ExtLite attribute set.
1003 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1004 as requested/supplid by Ere Maijala <ere@atp.fi>
1006 For generic frontend server, reverse the order of
1007 "toolkit-supplied / application-supplied" strings sent as implementationId,
1008 Name and Version. Also, remove the spaces around the slash. This brings
1009 the GFS in line with the behaviour of ZOOM-C on the client side.
1011 Add function ZOOM_scanset_display_term.
1013 yaz-client shows scan displayTerm if present.
1015 Utility yaz-iconv is now installed by default along with the man page
1018 Extend configure check for OpenSSL to use pkg-config where available (such
1021 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1022 server to specify uid/gid/mask for socket using the format
1023 unix:[user=uid,][group=gid,][umask=mask,]file=path
1024 If file= is omitted the existing format is assumed, e.g.
1026 in which case the mask is 0666 (rw for everybody).
1028 Major restructure of YAZ source. All source in libyaz is in src directory.
1029 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1030 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1032 Added man page for utility yaz-marcdump (used to be called marcdump).
1033 yaz-marcdump is installed by 'make install'.
1035 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1036 of incoming package failed.
1038 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1040 Change prototype of odr_perror: add const to message string.
1042 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1044 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1045 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1046 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1047 DNS lookup. There should not be any compatibility problems with this
1048 assuming that blocking=1 or 0 is used.
1050 Fix bad reference in UNIX comstack in function cs_addrstr.
1052 Fix for compilation on AIX.
1054 The generic front-end server (server/seshigh.c) now supports returning
1055 Init diagnostics to the client in User-information-field, in
1056 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1059 --- 2.0.4 2003/09/04
1061 Allow any CQL relation (not just all,any,exact,scr).
1063 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1064 that features the same UI.
1066 Implemented command update0 in YAZ client which is equivalent to
1067 update but uses old of Ext Update ASN.1.
1069 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1070 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1071 Previously no OID was used for this info.
1073 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1074 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1075 returns 'malformed search term' otherwise.
1077 SortResponse member resultCount now set to NULL in sort handler of
1080 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1083 Add three new utility functions for translating OIDs between various
1084 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1085 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1086 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1087 char *oid_to_dotstring(const int *oid, char *oidbuf);
1088 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1090 Reverted modifications for ES Update definition for z_IU0Update
1091 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1092 is back to YAZ 2.0.2.
1094 String value attributes for CCL parser.
1096 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1097 which their FirstSearch server returns in Init responses, sometimes
1098 carrying useful diagnostic information when Init fails. This has the
1099 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1100 "z39.50/oclcui.asn", where its definition is somewhat different from
1101 what OCLC document on their web-site, as required to interoperate with
1104 Support for anonymous authentication in yaz-client. Use the command
1107 * Fix the OID of the Index Data-local "admin" Extended Service from
1108 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1109 the 1000, which indicates a locally-defined OID, was a mistake.
1111 --- 2.0.3 2003/06/20
1113 Fix CCL directive @case handling so that it affects string match for
1114 both CCL keywords and qualifiers.
1116 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1117 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1118 Decoder has been updated with ASN.1 changes as listed in
1119 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1120 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1121 z_IUUpdate, remains unchanged.
1123 ZOOM_record_get may now return a record in a specific character set.
1124 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1125 "from" is the character set of record as returned by target. "to" is
1126 the character set to be returned. If omitted, "to" is UTF-8.
1128 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1130 New ODR utility, odr_getelement, which returns name of element for
1131 which encoding/decoding failed.
1133 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1134 in cases where a required element was omitted.
1136 Bug fix: some MARC8 sequences were not converted.
1138 New ZOOM option "step" which specifies number of records to be
1139 retrieved in one chunk. Used in conjunction with "start" and "count".
1141 SRW support for yaz-client. Use scheme http: to use it, e.g.
1144 yaz-client no longer does (un)intelligent character set conversions
1145 by default. Can be enabled with charset and marc_charset commands.
1147 xmalloc trace fix for 64-bit systems such as DEC alpha.
1149 Solaris 2.6 compile fix.
1151 New function, cql_strerror() translates SRW error codes, as returned
1152 by cql_transform_error(), into human-readable English strings. Used
1153 in yaz-client diagnostics when appropriate.
1155 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1156 converts it into a type-1 query which is sent to the server. This
1157 makes CQL available for use with all Z-servers, as opposed to the tiny
1158 minority that can handle CQL queries themselves.
1160 --- 2.0.2 2003/04/28
1162 New Debian package layout similar to the Redhat Package layout.
1164 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1165 and search result respectively.
1167 --- 2.0.1 2003/04/25
1169 Redhat package is now several packages: libyaz (runtime libraries),
1170 libyaz-devel (development and documentation, and yaz (utility programs).
1171 Package spec file by Morten Bøgeskov.
1173 New member 'schema' in struct bend_fetch_rr which the name of requested
1174 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1175 handler MAY set this to reflect the schema of the returned record.
1177 New member 'display_term' in struct scan_entry. GFS now sets member entries
1178 and allocates scan entries to be filled by user scan handler. In previous
1179 version, entries member was allocated by the scan handler. That still works,
1180 but the GFS will ignore member display_term - assuming it was NOT set by
1181 the handler. The fact that the GFS now allocates the entries both allows
1182 for new members and makes a scan handler easier to write.
1184 Fix CQL lex buffer overflow.
1186 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1187 SRU default recordPacking is string.
1189 SRU protocol support for frontend server.
1191 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1193 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1195 Added scan for the ZOOM shell (zoomsh).
1199 * String Identifers for Schemas (Amendment 5).
1200 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1201 Old definition for schema
1202 Odr_oid *schema; /* OPT */
1207 Z_InternationalString *uri;
1208 #define Z_Schema_oid 1
1209 #define Z_Schema_uri 2
1212 * resultCount parameter to Sort Response (Amendment 1).
1213 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1215 Support for SRW 1.0 over HTTP. This is an optional feature and
1216 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1219 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1220 on the same port. SRW SearchRetrieveRequests are mapped
1221 to bend_init,bend_search,bend_fetch,bend_close.
1223 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1225 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1226 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1228 ZOOM connections are SRW based if schem http is used for hostname
1229 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1230 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1232 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1233 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1234 distance=n, order=true/false, relation=le, prox unit=word. If
1235 n is omitted, distance 1 is used.
1237 Fixed problem with C compiler include path in wrong order.
1239 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1240 on Solaris. Patch from Ko van der Sloot.
1242 New MARC decode API. All new functions operate on a yaz_marc_t
1243 handle. The most important new functions are: yaz_marc_create,
1244 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1245 decode and destroy respectively. Decoder can produce formats
1246 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1247 include/yaz/marcdisp.h.
1249 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1250 to UTF-8, UCS-32, wchar_t or Latin-1.
1252 * Prototypes for yaz_iconv_-functions moved to separate header
1253 include/yaz/yaz-iconv.h.
1255 Make a few private functions 'static' in unix.c. This prevents
1256 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1258 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1259 are set when Init Response is received.
1261 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1262 but returns diagnostic set as well.
1264 New function yaz_strerror which is a portable wrapper for
1265 strerror/strerror_r/GetLastMessage.
1267 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1268 is returned for MARC. If type is "oai", then OAI MARC is returned.
1270 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1273 --- 1.9.2 2002/11/26
1275 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1277 Fix bad race conditions on SIGTERM and terminate gracefully in
1280 Move retrieval (data1) module to Zebra since nobody seems to be
1283 Add GRS-1 render for ZOOM using same format as yaz-client.
1285 --- 1.9.1 2002/10/05
1287 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1289 Fix broken ESpec handling in data1 module.
1291 SGML reader parses comments and makes them part of the data1 tree.
1293 Added several type casts so that YAZ compiles as C++ code.
1295 ZOOM didn't handle PDU encoding failures properly.
1297 Added more Bib-1 diagnostics (approved extensions).
1299 GNU configure: better check for iconv.
1301 More portable use of accept, getpeername. Check for socklen_t. Use
1302 int/size_t if socklen_t is not defined.
1306 PQF parser rejects bad queries - including those with extra
1307 characters in them. PQF parser used to silently ignore that.
1308 Cleaner API for PQF added, which allows you to get detailed
1309 error information for bad queries (see yaz/pquery.h).
1311 Fixed bug in ZOOM_record_get for type "database".
1313 Implemented mini iconv library supporting conversions between
1314 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1316 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1318 --- 1.8.9 2002/08/20
1320 Fixed ZOOM C record cache so that preferredRecordSyntax and
1321 elementSetName is used to check for already fetched records.
1323 --- 1.8.8 2002/08/02
1325 Added three members in bend_initrequest structure to facilitate
1326 character set negotiation.
1328 Fixed a bug in frontend server that could cause indefinite
1329 loops under rare conditions.
1331 Revised character set utilities (charneg.h) so that encoding
1332 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1334 For PQF, directive @term <type> sets term type for Scan/Search.
1335 Here <type> is general, string, numeric, null. The term type
1336 is inherited - just like @attr.
1338 New call odr_set_charset that sets character set conversion for
1339 international-strings on a ODR stream. Prototype is:
1340 int odr_set_charset(ODR o, const char *to, const char *from);
1341 The InternationalString is still represented as C string in YAZ
1342 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1343 won't). On the protocol level, you can use any encoding.
1345 Support for UNIX sockets in ZOOM.
1347 Solaris recv sometimes returns errno == ENOENT. It is treated as
1348 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1350 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1351 both client and server. Code by Morten Bøgeskov.
1353 --- 1.8.7 2002/05/22
1355 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1356 that they can be used directly from Visual Basic. You must recompile
1357 your windows APP if you're using ZOOM.
1359 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1360 Commands "lang" and "charset" sets language and character set respectively.
1361 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1362 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1364 Attributes from multiple CCL fields may be OR'ed rather than merged
1365 using directive "@field or". Fields are still merged by default -
1366 equivalent to "@field merge".
1368 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1371 Fixed bug in zget for parameter ExtendedServicesResponse.
1375 --- 1.8.6 2002/03/25
1377 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1379 Client displays USR.1:SearchResult-1 (hits per term).
1381 Additional Search Info for search in Generic Frontend Server.
1383 Fixed CCL parsing of "field=s".
1385 WIN32 installer - using the excellent NSIS software from nullsoft.
1387 Fixed CCL parsing of "field = - <number>".
1389 Added function yaz_marc_decode that decodes MARC for line mode
1390 display or XML (similar to that used by JZKit).
1392 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1393 Z39.50. But ISO/ILL was, however.
1395 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1396 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1398 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1399 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1401 --- 1.8.5 2002/02/03
1403 New YAZ client features: Command completion and new commands:
1404 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1405 Code provided by Jacob Poulsen.
1407 New call oid_trav, that visits all registered OIDs via callback.
1409 Function ZOOM_record_get now returns const char pointer rather than
1410 void pointer. It saves a lot of type casts.
1412 For YAZ client, command "auth" now allows you to set authentication
1413 in IdPass style. It is enabled when three tokens are given - order
1414 is user, group and password.
1416 Fix memory leaks in MARC record handling for ZOOM.
1418 New option for YAZ client, -k <kilobytes> that sets
1419 maximum record size. Similar to -k option for generic frontend
1420 server and yaz-ztest.
1422 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1424 Prefix query parser reports "fail" when bad attribute set is given.
1426 Fix in MARC decoder. Proximity logging. Fix for attribute set
1427 in scan handler for server. Patches by Shigeru Ishida.
1429 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1432 Configure option --with-openssl=<dir> now works when a directory is
1433 specified. Patch provided by Morten Bøgeskov.
1435 New option for YAZ client, -u <auth>, that sets authentication.
1437 ZOOM fix: error information was sometimes "missing", since error
1438 was cleared/reset too when it shouldn't.
1440 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1442 --- 1.8.4 2002/01/04
1444 Scan for ZOOM API. New object ZOOM_scanset. New functions
1445 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1446 ZOOM_scanset_destroy.
1448 New ZOOM function, ZOOM_connection_last_event, that returns type
1449 of last event (such as "receive data", "send data", "apdu received",
1452 New ZOOM option, schema, that specifies schema for retrieval.
1454 New CCL feature. Qualifiers can be aliases for one or more
1455 other qualifiers (if more than one is given, OR is used).
1457 ZOOM uses named result sets if target supports it.
1459 Two new YAZ client commands: . (dot, which sources a script of YAZ
1460 client commands), and ! (to execute shell command.). Implemented
1463 Working on Debian packages.
1465 --- 1.8.3 2001/11/19
1467 YAZ client enables named result sets only if target supports it.
1469 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1471 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1472 with key="host" to get same result.
1474 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1475 Function Z3950_resultset_record(s) returns references to records
1476 "owned" by resultset. To become owner use Z3950_record_clone.
1478 Function z_ext_record handles Extended Services. Thanks to
1481 --- 1.8.2 2001/11/12
1483 CCL Parser fix: ignore token comma when dealing with and-lists.
1485 Documentation updates for COMSTACK.
1487 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1488 Changed prototype Z3950_records. For some functions, int parameters
1489 were changed to size_t.
1491 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1494 New MARC decode/display function, marc_display_exl, which properly rejects
1495 non-ISO2709 records. YAZ client uses it.
1497 --- 1.8.1 2001/10/29
1499 Fix bug: local attribute set wasn't set correctly in PQF strings.
1503 * Old Z39.50 codecs no longer supported.
1505 Added ZOOM C binding. See http://zoom.z3950.org/
1507 Renamed states for COMSTACKs to avoid confusion with events.
1509 Implemented cs_look and proper cs_rcvconnect.
1511 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1513 Configure detects POSIX threads on OpenBSD.
1515 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1516 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1518 When error is returned from present handler, non-surrogate diagnostic
1519 is returned in present response (and fetch handler is no longer called).
1521 * Minor adjustments to pquery parser (PQF). Token characters may be
1522 escaped by using backslash (C-style).
1524 PQF parser allows string attribute values to be specified. For @attr,
1525 non-numeric characters after the equal-sign are treated as strings
1526 (e.g. @attr 9=title).
1528 CCL trunction character may be defined (@truncation in file)
1530 * function zget_ExtendedServicesRequest sets waitAction to
1531 waitIfPossible (was wait).
1533 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1536 CCL operator names may be set in field definition files (CCL_bibset).
1537 See ccl/bib1 for an example.
1539 Fixes in ASN.1 compiler for C++ compatibility.
1541 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1542 and "op_or" to avoid conflict with C++.
1544 Fixed problem with GNU readline detection on Redhat 7.0.
1546 Added step-size for Scan backend handler.
1548 Fixed bug that made the frontend server crash when no attribute
1549 set was specified for scan.
1551 Front-end server automatically switches to original working directory
1552 when installed as an NT service. Previously -w had to be specified to
1555 Added extended attributes for retrieval module (data1), so that data1
1556 records carry d1_readXML/SGML attributes. d1_read also supports
1557 null-data rules ( <tag/>)
1559 On UNIX when POSIX threads are available, a separate library libyazthread
1560 is created. Programmers should link with that library and the yaz library
1561 when using threads. The reason for the split was that some applications
1562 on Linux, such as Apache, doesn't work well when using shared objects that
1565 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1566 (or any frontend server) in SSL mode by specifying ssl: followed by
1567 address. Only tested on UNIX.
1569 Added feature for CCL module. Virtual structure s=al or s=ol generates
1570 and-list and or-list respectively instead of phrase search.
1574 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1575 log_mask_str. This was done to avoid name conflicts with other libraries
1576 (such as other PHP extensions).
1578 Added raw OID member for preferred record syntax (request_format_raw)
1579 and returned record syntax (output_format_raw) for backend fetch method.
1581 Config file yaz-config now accepts options so that it returns specific
1582 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1584 Shared library support for UNIX using GNU libtool.
1586 * Modified backend interface. Request/Response struct's replaced by
1587 one read/write C struct. For example bend_fetchrequest and
1588 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1589 Every handler - even search has to be registered in bend_init
1590 handler. This means that the YAZ library no longer refers to
1591 external functions and it makes it possible to make the whole
1592 thing a single DLL/SO.
1594 Added Segment handler for backend server.
1596 Added Zmbol/Zebra administrative functions to YAZ client.
1598 Threaded frontend server on UNIX (when POSIX Threads are available).
1599 Starting the server with option -T enables multi-threading.
1603 Added configure option --enable-comp/disable-comp to control use
1604 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1605 located in sub directory asn.
1607 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1608 in ${exec_prefix}/bin along with the other programs yaz-client and
1611 GNU automake used to maintain makefiles.
1613 Added several OID's.
1615 Changed retrieval module so that we can load records with no abstract
1616 syntax defined. Tagpaths in these records are fully composed of string
1619 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1623 On UNIX, the generated makefile now supports a proper 'make install'.
1624 The prefix can be set via GNU configure to set the install location
1625 (default is /usr/local).
1627 * YAZ programs client and ztest were renamed to yaz-client and
1628 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1629 locations, such as /usr/bin,/usr/local/bin,etc.
1631 * YAZ Header files were moved from include to include/yaz. YAZ Header
1632 files are referred to as include <yaz/log.h> rather than <log.h>.
1633 The YAZ include path (-I ..) is therefore the same as before. Programmers
1634 should update their #include statements or use -Ipath/include/yaz
1635 instead. The main motivation for doing this change is that YAZ header files
1636 can be installed in "standard" locations /usr/include,/usr/local/include
1637 without introducing conflicts, since ALL YAZ header files are stored
1638 in subdirectory yaz (under /usr/include for example).
1640 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1641 rather than project/workspace files. We switched because project files
1642 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1645 Changed name of logging function, logf, to yaz_log, to prevent name
1646 clash with some math-log functions. The YAZ header log.h defines logf
1647 to yaz_log (#define) so there should be no incompatibilities by this
1650 Added bend_start/bend_stop handlers for server. These handler are
1651 called on start/stop of server. For windows they are called whenever
1652 a service is started/stopped.
1654 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1655 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1656 in util/yc.tcl. The auto-generated C code structures are, in a few
1657 cases, incompatible with the old decoders. There are differences in the
1658 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1659 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1660 The preprocessor variable ASN_COMPILED is defined when the compiled
1661 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1662 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1663 wish to use the old encoders/decoders you can specify --disable-yc
1666 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1667 version so that it supports both new - and old version of DB Update
1669 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1670 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1671 change. The name parameter can be set to 0 in which no name is specified
1672 for the construction. The macros odr_implicit and odr_explicit sets name
1673 parameter to zero for the construction involved. New macros
1674 odr_implicit_tag and odr_explicit_tag are similar to the others,
1675 except that a name parameter is added. For programmers' that don't use
1676 ODR they probably only need to change the call to z_APDU and z_External.
1678 Added access control facility by interfacing the TCP wrapper library.
1679 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1680 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1681 name of the daemon and enables the access control as specified in
1682 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1684 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1685 den Dool <H.M.vdnDool@kub.nl>.
1687 Added reference ID parameter to most functions in server API - refer
1688 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1690 Changed name of ccl library to libccl.a (was ccl.a).
1692 Fixed bug in decoder for Explain (Category TargetInfo).
1694 Added support for GNU readline in client. Thanks to Jacob Poulsen
1695 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1697 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1698 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1699 IMPLEMENTATION! This change was made to the development version before
1700 the ZIG decided to retract the amendment. If any users MUST be
1701 compatible with the original Update definition, PLEASE CONTACT US, and
1702 we will include a separate definition corresponding to the old Update
1703 ES. Note that because of the change to the ASN.1 of the
1704 TaskPackageRecordStructure we cannot define a single structure that
1705 will support both versions.
1707 * Added const modifier to buffer parameter for some ODR/BER encoding
1708 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1709 completeWAIS, odr_dumpBER.
1711 Fixed bug in client.c which caused a crash when a scanResponse didn't
1712 contain positionOfTerm.
1714 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1715 * will cause an error in a client if a non-YAZ target sends both a
1716 * list of Scan entries and non-surrogate diagnostics.
1718 Retrieval module enhancements. Tag sets may be typed in the reference
1719 to it. From the .abs-file the "tagset" directive takes a third optional
1720 integer type for the tag set referenced. From a .tag-file the "include"
1721 directive takes a third optional type as well. The old "type" directive
1722 in the tag set itself is still recognized but acts as the default type
1725 Backend interface change. Individual Scan terms returned from bend_scan
1726 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1727 in include/backend.h.
1729 Retrieval module enhancements. Multiple tag sets and attribute sets may
1730 be specified in abstract syntax specs. Revised the error/warning for
1731 logging messages reported by the retrieval module when reading the
1734 Object Identifier system (oid_..) changed. The API is backwards
1735 compatible but the oid-routines now allocates new OID's when needed.
1736 Raw OID's may be specified in oid_getvalbyname.
1738 YAZ now uses GNU configure to generate Makefile(s).
1740 * Minor changes in some of the member names of DeleteResultSetRequest and
1741 DeleteResultSetResponse. See include/proto.h.
1743 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1744 and added member 'languages' in TargetInfo (which was missing).
1746 Changed the way attribute sets are handled in the retrieval
1747 module. These are now cached, just like the abstract syntaxes
1750 Changed YAZ so that it links with compiled ASN.1.
1752 Added Explain-schema definitions and mapping routines. The following
1753 Explain categories have been implemented: AttributeDetails,
1754 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1756 Fixed minor bug in Windows version of Server Library.
1758 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1760 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1762 Added EXTERNAL: UNIverse Resource Report (non-standard).
1764 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1765 ENUMERATED and SET OF.
1767 * Added 'const' to some of the char pointer arguments for the
1768 functions, data1_read_node, data1_getelementbytagname,
1769 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1772 Fixed bug in data1_insert_taggeddata - the last_child member of
1773 parent wasn't initialised.
1775 * Changed data1_read_record and data1_read_node so that the supplied
1776 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1777 doesn't refer to any parts of the "SGML"-buffer.
1779 Fixed bug in server library (Windows version of statserv_remove).
1781 * Changed code so that it compiles as C++. The type definition
1782 of Odr_fun which is a member of Odr_arm was changed. The result is,
1783 that an explicit typecast is needed for the fun pointer when
1784 using Odr_arm - as in:
1785 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1787 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1789 Implemented the new structured date and time definition as approved
1790 by the ZIG. Added schemaId element to the specificTag in Espec-1
1791 (also approved at the last ZIG). Thanks to RVDM.
1793 Added some Object identifiers (RVDM).
1795 Changed the Update Extended Service (RVDM).
1797 Added command "refid" to client which specifies referenceId for
1798 the following requests.
1800 Implemented extended service handling for server. See ztest.c
1801 for an example as well as backend.h. New handlers are registerd
1802 in the Init handler.
1804 * Changed interface for sort in server.
1806 Added new members to statserv_options_block. It allows a server
1807 to read options from another source than just the command line. Thanks
1808 to Charles Woodfield.
1810 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1811 renamed to zboolean. Some C++ compilers complained about the name.
1813 Minor changes to gils.abs. Added index 's' (sort) on title
1814 and date/time-last-modified.
1816 --- 1.4pl2 1998/1/30
1818 Fixed bug in server library regarding inetd mode (-i). This bug
1819 was introduced by release 1.4.
1821 --- 1.4pl1 1998/1/29
1823 Added sort facility in client and backend server interface.
1825 Fixed problem with dependencies in Makefile(s).
1827 Fixed bugs for encoders/decoders of extended services and
1830 Implemented sub-tree feature for schemas. Sub-trees are
1831 referenced in *.abs-files. See explain.abs for an example
1832 of the use of this feature.
1834 Modified bib1.att; local attributes for ANY didn't include
1835 ANY itself (only affects use of the retrieval module).
1837 Fixed bug in plain SGML reader in function data1_read_node:
1838 tags with prefix "var" was incorrectly interpreted as variants.
1840 Added feature "sub-schemas" to enable references to - and definitions
1841 of - group of elements.
1843 * Removed member parent from type data1_element (in data1.h).
1845 Implemented function odr_nullval() that returns the value of
1848 * Removed member num_children from data1_node (in data1.h).
1850 Made NT service interface part of the server library. The
1851 function statserv_main uses the NT service when required and
1852 calls the statserv_start / statserv_close routines.
1854 Routine zget_SearchRequest and zget_PresentRequest fills
1855 resultSetName/Id member with "default" instead of "Default".
1857 Fixed memory leak in server. Request queue member wasn't freed.
1859 Fixed nmem_exit so that memory is freed.
1863 Revised the CCL parser utility to be thread safe.
1865 Added function, oid_ent_to_oid, to replace the function
1866 oid_getoidbyent, which is not thread safe.
1868 * Added nmem_init and nmem_exit to initialize and release
1869 NMEM resources. Function nmem_init should be called once in the
1870 initial thread before NMEM/ODR is used. statserv.c and client.c
1871 have been changed accordingly. The change was necessary to make
1872 NMEM thread safe. The NMEM memory pool is shared amongst threads
1873 in a process. Unix-based applications will still work fine without
1876 Added NT Services interface for the the Z39.50 (statserv) Server.
1877 Refer to the ztest.c source on the usage.
1879 Windows 95/NT port using MSVC5.0. Project files are included in the
1882 * Defined new 'global' handle for the retrieval (data1) system. The
1883 new handled, data1_handle, describes the state of the data1 system.
1884 This handle is passed as first argument to virtually all
1885 data1 related routines. The functions data1_create and data1_destroy
1886 creates and destroys a data1 handle respectively.
1888 Added ODR encode stream member to all backend request structures
1889 init, search, scan etc. This stream should be used to allocate all
1890 memory used for the response when thread safe operation is needed.
1892 Changed the comstack utility, cs_addstr, to be thread safe. The
1893 returned hostname string returned by the function is now part the
1896 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1897 function. The cs_straddr takes a COMSTACK handle as argument, so this
1898 function must be used after cs_create and before bind/connect.
1899 This function is thread safe.
1901 Moved test server to 'ztest' directory - generic server code still
1902 in 'server' directory.
1904 Made prefix query (pquery.c) utility thread safe.
1906 Added new function modifier YAZ_EXPORT to 'export' public DLL
1907 functions when using windows (see include/yconfig.h).
1909 Added definitions to the OID database (util/oid.c) (RVDM).
1911 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1913 Added call to ccl_rpn_delete in client program.
1915 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1916 release of RPN structure.
1918 Added support for C++, headers uses extern "C" for public definitions.
1919 With input from RVDM.
1921 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1922 Thanks to Ronald van der Meer (RVDM).
1924 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1926 Added support for private extensions to the OID database
1927 (oid_setprivateoids()). Thanks to RVDM.
1929 Added optional, physical ANY (key replication)
1931 Fixed null-reference problem in GRS-1 output filter.
1933 Proximity operator added to Prefix Query Format (PQF).
1935 In test client command "base" accepts multiple databases.
1937 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1941 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1943 Smallish bug-fixes in the new encoders/decoders (explain).
1945 Bug fixed in DeleteRequest.
1947 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1949 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1951 Added SOIF syntax (using private OID for now) to retrieval module and client.
1953 Added Update extended service.
1955 Added SearchResult-1 additional info structure.
1957 Added optional CCL (ISO8777) interpreter as separate module. Available
1960 --- 1.2 1996/6/10 (1st anniversary release)
1962 Added Summary record syntax. Lightly tested.
1964 Added OPAC record syntax. Untested.
1966 Added ResourceReport service encoders/decoders. Untested.
1968 Fixed bug in z_Unit - wrong tagging on unitSystem.
1970 Fixed bug in the DiagRecs decoder.
1972 Added options for max PDU size and session timeout to frontend-server.
1974 Added documentation of query-language parsers and other supporting utilities.
1976 [frontend-server] Added Attribute set to the bend_scanrequest API.
1978 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1979 surrogate diagnostics were generated.
1981 [retrieval] Allow multiple local values for attribute.
1983 [retrieval] Allow multiple attributes per element in .abs files. index type.
1985 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1987 --- 1.1pl2 1996/4/10
1989 Minor changes, mostly specific to Zebra's requirements (retrieval)
1993 Repaired bug in frontend server when running multiple listening
1994 endpoints in dynamic mode.
1996 z_External() now won't break if a known, ASN.1 value comes encapsulated
1997 in an octet-string. The value will pass through unmodified in an Odr_oct.
1999 Added a bit of code to the demo client to decode & display
2000 ASN.1-structured records represented in the octet-aligned branch of
2001 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2003 Added z_ext_getentbyref() to the ASN module. Doc updated.
2005 * Completed the SCAN definition in the ASN module. This may break SCAN
2006 code based on older YAZ-versions at compile-time. The fix is easy -
2009 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2010 under the SCAN definition. Remember to initialize this, server-people.
2012 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2013 that this does not extend to ODR and ASN.
2015 Comstack allows insertion of established socket (primarily for
2016 inetd-operation of servers). Doc updated.
2018 Front-end server can now start from the inetd in TCP mode. Doc
2021 --- 1.0pl4 1996/1/24
2025 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2026 the rank and record number.
2028 Adjustments to the frontend server.
2030 Fixed diagnostic BER dumper. It ignored the file argument.
2034 Various changes to retrieval module.
2036 Changed the union discriminators of the protocol files from enums to
2037 ints paired with #defines.
2039 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2042 *Changed operator in the RPN structure to 'roperator', again to avoid a
2045 Fixed problems in Explain decoders/encoders.
2047 --- 1.0pl2 1995/12/6
2049 Memory bug in log module fixed.
2051 --- 1.0pl1 1995/12/5
2053 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2055 Bug in Explain DatabaseInfo module fixed.
2057 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2061 The shift to v1.0 signals that we now consider the *core* functionality
2062 of YAZ reasonably stable (the core being more or less equivalent to
2063 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2064 tested (Explain not at all - though that will happen soonish).
2066 Minor changes to code to support Windows port.
2068 Various minor changes after we're getting to use GRS-1 & co. more.
2070 Added Espec-1 format.
2072 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2073 of the protocol and it cannot be selected when encoding (maps into 'string'
2074 when decoding). Needed to talk to some servers.
2076 Demo client can request simple element set names.
2078 Added Diagnostic Format encoders/decoders.
2080 Added simple Close handling to frontend server (no hooks for resource
2081 reporting yet), and demonstration client.
2083 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2085 --- 1.0b3 1995/08/24
2087 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2088 handled incorrectly when records were requested in the searchResponse. This
2089 will only affect you if you use the frontend-server.
2091 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2092 Test-client will ask for and print GRS1. Ztest will return dummy records
2095 Added Explain encoders/decoders to the service-level API. Untested.
2097 Added Extended Services: Item Order encoders and decoders to the Service-
2098 level API. Untested. We could use a recent copy of the pertinent bits
2099 of the ILL protocol to add those bits.
2101 Added diagnostic format 1 encoders/decoders to the service-level API.
2104 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2105 odr_cons.c, which causes a more correct output.
2107 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2108 was always set to 0 when no records were requested in the searchRequest.
2110 * Added better external-handling. This shouldn't harm old code that
2111 *encodes* externals. It can break code that looks for a
2112 'single-ASN1-type' representation, since those types that are known
2113 are now decoded immediately. Look at the SUTRS sample code in
2114 seshigh.c and client.c. Documentation updated.
2116 Handling of structured records in bend_fetchresponse. Length -1 marks
2117 structured record, type is deduced from format field.
2119 --- 1.0b2 1995/06/27
2120 Fairly quick maintenance release to add SUTRS support.
2122 Fixed handling of SUTRS records in the demonstration client.
2124 * Added format field to the bend_fetchrequest and bend_fetchresponce
2125 structures of the backend API (frontend server). When the record is
2126 returned, the value of the format field is mapped to an OID. The
2127 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2128 of the record. The special value VAL_NONE in the bend_request means
2129 that no specific format was requested by the client. Documentation
2130 updated accordingly. Test server (ztest) will return a fixed dummy
2131 SUTRS record if your client requests SUTRS.
2133 Documentation updated accordingly.
2135 You can now set external libraries and RANLIB support in the top-level
2139 First public release.
