1 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
3 For OID class, use oid_class consistently.
5 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
8 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
9 character set for bibliographic information interchange". By Giannis Kosmas.
11 Added documentation on new OID API.
15 Changes to generic frontend server interface: added new member
16 'query_charset' for bend_initrequest structure. A backend init handler
17 should set this member to its native character set for query terms.
18 When defined, the frontend server logic will announce this character set
19 to a client if the negotiationModel bit is set by the client. All server
20 implementors are encouraged to specify this. If a backend server does not
21 specify this a warning is issued using yaz_log(YLOG_WARN,..).
23 Added CCL utility to remove terms (stop words) from resulting RPN
24 tree. This is handled by functions with prefix ccl_stop_words_ .
26 New ZOOM C option, "rpnCharset", which allows client-side conversion of
29 Clean-up the CCL API. Moved some internal structures from ccl.h to
30 private header cclp.h. Changed ccl_parser_create so that a Bibset must
31 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
32 This is replaced by ccl_parser_find_str which takes a string instead.
34 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
35 libyaz.la is the core of YAZ except the generic frontend server and
36 does not depend on POSIX threads anymore. libyaz_server.la is the
37 generic frontend server facilities and uses POSIX thread functionality
38 if available. The libyaz.la no longer depends on POSIX threads because
39 the number of global structures is limited. NMEM no longer re-uses blocks
40 between threads ; it simply free's memory immediately but allocates in
41 "large" chunks as usual. We don't expect any performance penalties
42 because of this. The yaz_log system is still using a global log_level so
43 caution must be taken when modifying it with yaz_log_init_.. +
44 yaz_log_mask_str. This, however, should not cause any trouble because
45 these functions are called during initialization of application code
46 anyway. `yaz-config --libs server` returns libs for server applications;
47 `yaz-config --libs` returns libs for non-server applications.
49 New OID database - with public definitions in oid_db.h. Removed old OID
50 database including the head oid.h and definitions such as enum oid_value
51 and struct oident. The new OID database uses the same string names as
52 before but the 'protocol' is gone. There are now only two representations
53 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
54 converts from string to OID; functions with prefix yaz_oid_to_string
55 converts the other way.
57 Change to emit_term() in CQL-to-PQF query translation: when a term has
58 the /regexp relation modifier, do not process it for leading and
59 trailing "^" and "*", which have quite different meanings in regular
62 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
63 write handlers no longer carries a 'last' parameter. This will make
64 yaz_iconv flush "less" characters. A flush is performed by call to
65 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
67 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
68 removed, because function yaz_query_to_wrbuf does the same.
70 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
71 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
73 Deprecated MARC utility functions removed.
75 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
78 Branch split: YAZ_2_1_55_branch
82 Fix to ZOOM-C so that transparent reconnection is properly handled on
83 connections that are in asynchronous mode.
85 Fixed compilation on OpenBSD 4.0.
87 Large strings in GRS-1 records are now properly displayed in yaz-client.
89 Added character conversion support for "advancegreek"; based on patch from
92 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
93 sequence is met. Before the error was not set so it would be unknown.
95 Adjust yaz-marcdump MARC reader so that it skips until record separator
100 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
101 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
102 fd_set structure used as a bitmask for the FDs to be selected on.
104 Using ACX_PTHREAD macro to check for POSIX threads.
106 Fixed have-vsnprintf check.
108 --- 2.1.50 2007/02/23
110 Fixes for configure on BSD. Bug #900.
112 Added snprintf/vsnprintf wrappers for systems that don't have
113 limits (heavens forbid).
115 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
116 created before all previous tasks were completed and removed from the
117 task queue, the new task could be removed by a mistake.
119 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
121 Implemented pass-through CQL-to-PQF conversions. Bug #861.
123 Fixed bug #832: Problem with MARC/charset in yaz-client.
125 Fixed bug #668: save command line history for yaz-client.
127 Fixed bug #830: pkg-config support.
129 --- 2.1.48 2007/01/23
131 Extended ZOOM result set options with two options that may be read by
132 a client: resultSetStatus and presentStatus with values as specified for
134 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
136 Fixed bug #827: Using SSL fails on Debian etch.
138 Fixed bug #826: Weird looking chars for set of MARC records.
140 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
141 that is treated as an ItemOrder with itemRequest being an XML document
142 external. The value of "doc" is the content.
144 Extended the GFS search facility. New member of bend_search_rr
145 'estimated_hit_count' signals that hits is known to be an estmate
146 (higher or lower than real hit count). New member 'partial_resultset'
147 signals that the search was partial (hit count is lower or equal than
148 real hit count). For Z39.50, the information is stored in resultSetStatus
149 member of SearchResponse APDU. For SRU, the information is signalled
150 via SRU diagnostic 59: "Result set created with valid partial results
153 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
155 --- 2.1.46 2007/01/13
157 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
159 Added ZOOM_connection_peek_event.
161 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
162 the following new functions:
163 ZOOM_event_nonblock, ZOOM_connection_process,
164 ZOOM_connection_get_{socket,mask,timeout},
165 ZOOM_connection_fire_event_{timeout,socket}.
166 The existing blocking event handler, ZOOM_event, is a wrapper for the
167 + blocking ZOOM_event_sys_{poll,select}.
169 Implemented function ccl_xml_config which parses XML version of CCL
170 configuration (bug #798).
172 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
174 Added timings utility (yaz/timing.h)
176 --- 2.1.44 2007/01/03
178 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
181 Fixed bug #779: Rotation of apdu.log fails.
183 Fixed for character set conversions:
184 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
185 Honor G1 set in MARC-8 decoding.
187 --- 2.1.42 2006/12/17
189 Fixed bug #775: char conversion does not handle Alternative UTF-8
192 Implemented function yaz_marc_read_line which parses MARC line format
193 records. There is a wealth of formats out there. So far, this function
194 reads line records produced by yaz_marc_write_line.
196 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
197 more generic and easier to remember(!) options: -i format and -o format
198 which specifies input format and output format respectively - where
199 format is one of "marc", "marcxml", "line", "marcxchange".
201 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
202 does not print anything except warnings for records.
204 For yaz-marcdump, added support for MARC split into files (-s) with a given
207 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
208 spec, at http://www.loc.gov/standards/sru/record-update/
209 This has changed the binary layout of the following structs:
210 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
211 bend_update_rr . Patch by Ko van der Sloot.
213 Added GFS utility function bend_assoc_is_alive which returns 1 if
214 association is still alive (client is connected); 0 otherwise (client
215 closed connection). This allows busy servers to stop working for
218 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
219 been a separate piece of software. This version of ziffy has been modified
220 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
222 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
224 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
225 Client code may now interrogate options such as "init_opt_sort" to
226 find out whether the server claims to support various options.
228 --- 2.1.40 2006/11/27
230 Added utilities yaz_{set,get}_esn to set/get element set name from
233 Removed the build of libyazthread.la. The libyaz.so is the threaded version
234 of YAZ and has been so since YAZ 2.1.10.
236 Implemented ZOOM_record_error which returns error information for
237 record (surrogate diagnostic).
239 --- 2.1.38 2006/10/31
241 Updates for SRU Update by Ko van der Sloot:
242 1. Changed name from "operation" to "action"
243 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
244 versions in the code, marked as 'backward compatible'.
245 3. Added diagnostics for SRU Update.
247 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
249 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
251 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
253 For GFS, fixed problem with SRU diagnostic 'First record position out of
254 range' being issued for 0 hits.
256 zoomtst10 part of Windows Build.
258 --- 2.1.36 2006/10/13
260 Implemented yaz_filepath_comp which splits a path into file path
261 components (required by Zebra 2.0.3+).
263 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
264 BSD inspired license until now so this should not have any real impact on
265 anybody. See http://www.opensource.org/licenses/bsd-license.php
267 Fixed bug #687: Missing log lines.
269 Fixed bug #678: CQL to PQF translation does not preserve double-quote
272 Fixed bug #689: SRU diagnostics to be added.
274 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
275 whether a connection is idle (no more work do do).
277 --- 2.1.34 2006/10/04
279 Change type of optval from long to int for invocation of setsockopt with
280 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
282 Added support for specifying the max log file size for the Generic
283 Frontend Server. The size is given with option -r.
285 --- 2.1.32 2006/09/21
287 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
289 --- 2.1.30 2006/09/17
291 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
294 Fixed bug in Generic Frontend Server that could cause a server to stop
295 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
297 For the generic frontend server, the maximum record size is used as maximum
298 size of incoming packages (SRU + Z39.50). The value until was previously
299 only used in Z39.50 Init negotiation and, later, in a session controlled
300 sizes of records returned. This is controlled using -k option. It can be
301 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
303 --- 2.1.28 2006/09/04
305 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
308 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
310 New option for yaz-marcdump -lpos=value which allows setting a portion
311 of MARC header to a certain value.
313 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
315 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
316 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
318 --- 2.1.26 2006/08/15
320 Fixed problem with SRU mode type (soap, get, post) for yaz-client
323 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
325 --- 2.1.24 2006/08/08
327 Fixed MARC ISO2709 encoding routines to deal with character set
330 Minor changes to GFS logging. Database included in search request log
333 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
334 cached/multiple records.
336 Shared libraries are built by default on Unix+configure.
338 Changed cql2pqf transformation to use a different evaluation order. The
339 new order is: always, relation, structure, position, truncation, index
340 and relationModifier. Old order was: always, relation, relationModifier,
341 structure, index, position, truncation. Note that the the latter ones
342 override former ones for identical attributes.. The new scheme means that
343 it is possible to override any existing attribute with a relationModifier.
344 And also that it is possible to override everything for the index rule
345 (except the ones listed in relationModifier). No order is perfect but this
346 one, we believe, covers more real cases.. The "always" should have been
347 called "default", since the attributes there can be overridden with all
350 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
351 compilation phase, but also for yaz-config --cflags output. This allows
352 us to have public headers with Libxml2 stuff in them . It should also,
353 eventually, make Libxml2 checks redundant in packages using YAZ, such
356 --- 2.1.22 2006/06/15
358 Changed SRU update structure bend_update_rr so that SRU diagnostics are
359 stored in uri, message and details.. Previously diagnostics were stored
360 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
361 compatibility.. but he's probably the only one affected, so.
363 Added support for CCL, compiled on the client side, in ZOOM-C. This
364 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
365 input; the resulting query objects can be used for for searching with
366 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
368 YAZ' configure searches for OpenSSL by default.
370 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
371 SL_CTX_use_certificate_file. See
372 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
373 for more info. Thanks to Ko van der Sloot.
375 --- 2.1.20 2006/06/02
377 Bug #600: SRU GET, POST support for yaz-client. Introduced
378 command 'sru' which selects method SOAP/GET/POST.
380 Allow missingValueAction to be specified for the sortspec string -
381 function yaz_sort_spec. By default, the missing value action is null.
382 Use ! to specify "abort". Use = followed by stringvalue to specify default
385 Ensured that Present-handler (if defined) is called in GFS before any call to
386 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
387 searchRetrieve requests.
389 Documentation for YAZ is now based on the Docbook XML/XSLT using
390 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
391 is no longer depending on jade/openjade or docbook-to-man scripts.
392 PDF is no longer part of the distribution - but can optionally be
393 made using DSSSL/jadetex or FOP.
395 Added retrieval handling support in Generic Frontend Server to support
396 conversion between MARC/XML as well as XSLTtransforms. See
397 etc/yazgfs.xml for an example.
399 Added Authentication support to Generic Frontend Server in SRU
400 mode. Authentication using HTTP Basic is supported, as is the use
401 of 'x-username' and 'x-password' parameters in the request itself.
403 Added support for a new character set MARC8s identical to MARC8 except
404 that it converts combined characters to single Unicode characters in the
405 Latin-1 range (when possible).
407 --- 2.1.18 2006/04/24
409 ASN.1 compiler 0.4: generates brief Doxygen file header for
410 generated .h/.c files.
412 Utility yaz_iconv now supports conversion to MARC-8.
414 New facilities for the MARC module. The reading - and writing of
415 content are separate methods for the yaz_marc_t handle. The following
416 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
417 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
418 format). Write functions have prefix yaz_marc_write_.. The existing
419 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
420 available. Removed support for OAI-MARC and simplexml (not the
421 simplexml from PHP5).
423 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
424 to be returned for this connection.
426 --- 2.1.16 2006/03/31
428 Allow multiple languages and charsets to be specified with
429 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
430 negcharset iso-8859-1,utf-8
432 Translation of proximity nodes from CQL into PQF now works.
434 Moved to automake 1.8, 1.9.
436 Added function yaz_log_set_handler which allows a log handler to be
437 installed. This handler will be called for all log messages. Output
438 to file is also produced; but that can be disabled by passing NULL
439 fname to yaz_log_init_file.
441 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
443 For SRW (including GFS), accept application/soap+xml as content-type
446 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
447 produces NO stylesheet reference even if a default stylesheet is specified
450 --- 2.1.14 2006/03/14
452 Updated Windows package to include yazd.dll + yazd.lib for the
453 Development component.
455 If the environment variable YAZ_LOG is set, then it is used as a
456 string indicating the default level of logging to use if not
457 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
458 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
459 used as before. So, for example, to omit warnings from YAZ logging,
462 cql_transform() now map structure and other attributes before indexes,
463 so that index-specific structures and other attributes can override
464 defaults. So now a combination of mapping specifications such as:
466 index.dc.date = 1=date-modified 4=5
467 does the right thing.
469 cql_transform() now also respects the "always" mapping specification,
470 which establishes an initial set of attributes to be used for all
471 terms except where overridden by more specific attributes associated
472 with the index, relation or modifier.
474 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
475 which mode to use; one of "post", "get" or "soap" (SRW, default).
477 Fixes for yaz_iconv routines: changed trie-based character set conversions
478 to use only non-negative values for bit fields due to Sun's C compiler not
479 supporting negative values.
481 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
482 sequences where not read correctly. Fix by Rustam Usmanov.
484 Updated win/makefile to use options, settings which makes things
485 compile with VS C 2005.
487 --- 2.1.12 2006/02/01
489 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
491 In ZOOM socket code, use select instead of poll on MacOSX.
493 ZOOM-C now support client-side compilation of CQL into RPN that is
494 sent to the server, enabling CQL to be used against all Z39.50
495 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
496 ZOOM_query object, and submit it using ZOOM_connection_search().
497 The CQL-to-RPN translation uses a configuration file, the name of
498 which must be specified in the Connection's "cqlfile" option.
500 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
501 function, which takes as its start-term parameter a ZOOM_query object
502 (which may have had either CQL or RPN set into it).
505 --- 2.1.10 2005/11/29
507 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
508 GFS to support this as well. Backend handler, bend_srw_update, does the
509 update work. Code contributed by Ko van der Sloot.
511 Allow retrieval of Search Result-1 information in ZOOM by the use of
512 options that are attached to a result set. ZOOM documentation updated
515 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
516 UTF-8 conversion. Patch by Raj Patel.
518 Added option -m to GFS to control formatting of timestamps in log file.
520 Added 'exit' as synonym for 'quit' in yaz-client
522 Added support for specifying SRW resultSetId + resultSetIdleTime in a
523 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
524 for the new members. Patch by Ko van der Sloot.
526 Added support for SRU POST. It is supported for content-type
527 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
529 Do not build the separate Multi-threaded (MT) library libyazthread.la.
530 Instead make the library libyaz.la multi-threaded. Threading as a whole
531 can still be disabled by configure option --disable-threads. Previosly,
532 with older GLIBCs there were problems with MT libs under Apache. This
533 has now been fixed a long time ago.
535 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
538 CQL module modified to be case insensitive for relations/indexes/operations.
540 Fixed bug in CQL transform code: incorrect value relationModifieder
543 Added 'show all' command for yaz-client which retrieves all results
546 Added new yaz-client, xmles, which takes a (private) OID and
547 a document to be sent as an extended service request.
549 Describe new yaz-client commands wait_response and set_auto_wait.
551 Increase TCP/IP listener backlog from 3 (which I am guessing was
552 copied from the SunOS manual entry way back when) so SOMAXCONN, so
553 that the socket will queue as many incoming connections as it's able
554 to handle ongoing connections. In other words, it will never now
555 refuse a connection that it would be able to handle merely because
556 it's not got around to accepting() enough of the pending connections
557 yet. This is the behaviour anyway under Linux, where the listen()
558 argument is ignored; but not under BSD and on systems such as
559 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
560 YAZ-based servers should now be uniform across operating systems in
563 yaz-marcdump uses 64-bit file access on some systems. This is enabled
564 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
565 This allows yaz-marcdump to read large MARC batches (>2 GB).
567 Modified all YAZ source files - except the source which is auto-generated
568 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
571 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
572 corresponding to the existing *_setl() function. These allow option
573 values containing arbitrary valuues.
575 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
576 ZOOM_resultset_sort() in new applications. Its behaviour is identical
577 except that it returns an indicator of whether or not the sort
578 criterion was accepted (0 for OK, -1 for invalid).
582 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
583 MARC output rather than returning "new" buffer.
585 yaz-client warns about unknown init options.
587 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
591 Added support for SRW sort in Generic Frontend Server. Patch
592 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
593 sortKeys - or NULL if none is provided.
595 Fixed bug #307: It was impossible to specify indefinite/no timeout
596 for ZOOM_event. Special timeout value -1 now means indefinite timeout
599 Added support for multiple languages and charsets to be specified in
600 ZOOM. Each charset/language is separated by a blank. If negotiation is
601 in effect in init-response, Option
602 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
603 Code based on patch by Vasiliy Osadchuk.
605 Fixed bug #306: infinite recursion that occurred when calling
606 yaz_log_level_init as the first call (before other log level or
609 Fixed bug in scan handling in front end server: if preferred-Position-In-
610 Response was non-present, a NULL pointer referece was performed.
614 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
615 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
616 now defined for all those error codes. So instead of putting 109 in
617 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
618 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
620 Modified the yaz-marcdump utility to skip garbage bytes between MARC
623 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
625 Program yaz-client now exits and produces an error message if multiple
626 Z39.50 servers are specified on the command line (none or one allowed
629 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
634 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
636 Fixed bug #272: Preserve spacing for CCL terms.
640 Added support for virtual hosts and multiple backend servers for
641 the YAZ frontend server. The configution is XML based and
642 support specificition of CQL to RPN mappings and explain information.
643 See section "Virtual Hosts" in the YAZ manual.
645 Extended OPAC display utility. OPAC display utility renders
646 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
647 to supplement yaz_marc_decode_wrbuf.
649 Fixed a bug in MARC decoder that could caused it to crash for some
650 invalid MARC records. More diagnostics and warnings where added in
651 XML output (warnings, etc are stored in comments).
653 --- 2.0.34 2005/02/08
655 Fixes for UNIX domain sockets. Bug #261.
657 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
659 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
660 Added yaz_marc_subfield_str which defines subfield lead string which is
661 used in YAZ_MARC_LINE format. Default string is blank+$. Added
662 yaz_marc_endline_str which defines end of fields string used in
663 YAZ_MARC_LINE format. Default string is newline.
665 Experimental support for MarcXChange. This format can be produced
666 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
667 http://www.bs.dk/standards/MarcXchange.xsd
669 Added yaz-client commands scansize that sets maximum number of
670 entries to be returned by scan.
672 --- 2.0.32 2005/01/11
674 Added support for SRW scan in yaz-client and Generic Frontend Server.
676 * Added whereInList member to SRW Scan Term.
678 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
680 Fixed NMEM system to return aligned blocks on the smallest boundaries
681 that are suitably aligned for all possible types on the particular
682 architecture YAZ is being built for.
684 --- 2.0.30 2005/01/04
686 Fixed numerious warnings that was issued with newer versions of GCC.
688 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
689 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
692 Make YAZ Generic Frontend Server slightly faster.
694 Enhance (and reduce) logging for Generic Frontend Server.
696 Revert YAZ log system so that it flushes every write operation
697 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
699 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
700 instead of LOG_, due to name clash with syslog(3). LOG_ are still
701 present. New applications should define YAZ_USE_NEW_LOG=1 - this
702 will effectively disable old definitions.
704 --- 2.0.28 2004/11/09
706 Added yaz_log_time_format which specifies log format using
709 Added yaz_log_module_level which returns mask for a module. Value
710 is non-zero mask a if module is enabled; zero if disabled.
712 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
713 in include/yaz/cql.h.
715 Fixed bug #176: Dont throw diagnostics on empty SRU args.
717 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
719 Fixed bug #172: RPM builds does not enable SSL.
721 Doxyfile.in part of dist. Doxyfile generated by configure.
723 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
724 are given and the corresponding component does not exist.
726 Extend CCL documentation in YAZ reference. Describe r=r.
728 --- 2.0.26 2004/10/01
730 Fixed MARC->MARCXML conversion to properly deal with
731 fields, subfields, indicators having non-ASCII characters.
733 Fixed MARC->MARCXML conversion so that ASCII control characters
734 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
737 Added YAZ GFS support for conversion from Z39.50 surrogate
738 diagnostics to SRW surrogate diagnostics.
740 Bug fix: YAZ GFS did not return schema in explainResponse.
742 --- 2.0.25 2004/09/30
744 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
745 now converts recordSchema to elementSetName as well as schema URI.
747 Fixed bug in COMSTACK that prevented HTTP request packages from being
750 --- 2.0.24 2004/09/29
752 Added CCL facility r=r "range" which is similar to r=o "ordered" but
753 does not require white-space before and after the dash in a range, e.g.
754 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
757 Fixed a few AC_TRY_LINK configure tests that did not operate properly
758 due to new GCC removing "redundant" code.
760 Added yaz-client commands scanpos and scanstep that sets preferred
761 position and step-size for scan.
763 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
765 Added CCL utility ccl_qual_buf which parses one or more CCL
766 spec lines in a buffer.
768 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
769 of name and value - ignoring empty lines and comments.
771 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
773 Added odr_get_element_path which returns current element path for an
774 ODR handle. This utility is useful in error handling or user-defined
777 Added ODR_PRINT utility odr_set_stream which is is a more generic
778 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
779 to a write function and pointer to close function. The close function - if
780 non-NULL - will be called during odr_destroy.
782 Fixed bug in CCL parser where truncation char was not removed from
783 right side when truncation=both was in effect.
785 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
788 --- 2.0.23 2004/08/11
790 Fix buffer overrun in CQL parser when dealing with proximity (%).
792 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
793 to UTF-8/UCS conversion is now only based on codetables.xml.
795 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
797 --- 2.0.22 2004/08/06
799 Add support for more "commit changes" in ZOOM (uses Extended Services).
801 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
804 Yet another small fix for configure of SSL.
806 --- 2.0.21 2004/05/14
808 Fix SSL libs for configure when --with-openssl=DIR is given.
810 --- 2.0.20 2004/05/10
812 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
814 SSL comstack now uses yaz.pem certificate file on server side
815 by default. Certificate filename can be configured by calling
816 comstack function cs_set_ssl_certificate_file before cs_bind is used.
818 Fix bug regarding multiple calls to ZOOM_connection_connect.
820 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
822 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
823 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
825 ZOOM now allows inspection of X509 peer certificate for verification.
826 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
828 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
829 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
830 as "modular" but it simplifies things.
832 Added cs_get_peer_certificate to that returns peer X509 PEM.
834 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
835 NULL if SSL is unavailable.
837 Documentation about MARC decoding tools.
839 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
841 --- 2.0.19 2004/03/30
843 Rename CHANGELOG to NEWS to follow GNU style packing.
845 Fix bug with missing initialization of member in init_diagnostics.
846 This bug affects threaded version of GFS server.
848 --- 2.0.18 2004/03/20
850 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
853 Ensure zlib.dll is packed with Windows install.
855 --- 2.0.17 2004/03/17
857 Fix encoding of xsd:string to use text instead of CDATA.
859 Fix endless loop in CQL parser with unbalanced ".
861 Use a more compact way to store MARC-8 conversion tables.
863 --- 2.0.16 2004/03/16 Debian only
865 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
868 Update CQL parser to use new CQL 1.1 modifiers for booleans and
873 --- 2.0.15 2004/03/01
875 Another fix for decoding of XML packed records.
877 --- 2.0.14 2004/02/25
879 Fixes for Chunked encoding. White space not ignored after length spec.
881 Update NS and use default NS for SRW diagnostic elements.
883 --- 2.0.13 2004/02/23
885 Implement ZOOM_resultset_cache_reset which resets record cache.
887 Implement ZOOM_resultset_sort which sorts a result set.
889 Implement chunked HTTP transfer.
891 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
893 --- 2.0.12 2004/02/16
895 Added member 'schema' to bend_explain_rr structure so that backend
896 can specify explain record identifier. Defaults to Zeerex 2.0.
898 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
900 --- 2.0.11 2004/02/16
902 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
905 Added init command for yaz-client which sends "extra" init request.
907 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
908 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
910 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
912 Make ZOOM error code for "invalid query".
914 Fixed compilation for SSL which wasn't properly enabled for all platforms.
916 --- 2.0.10 2004/02/05
918 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
921 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
923 Added option -p <file> to make Generic Frontend Server to write PID file.
925 Added option -D to put Generic Frontend Server in background on its own.
927 Make ZOOM C recognize option "password". If unset, "pass" is used
928 (for backwards compatibility).
930 Fixed a bug in Generic Frontend Server that could make it crash if a
931 client sets characterSetNegotation bit, but didn't pass negotiation stuff
934 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
935 Must be issued before open, in order to be in effect.
937 --- 2.0.9-6 2004/01/12 Debian/Windows
939 Make the SRU server more picky WRT unknown params, etc.
941 Bug fix: ZOOM scan response didn't return displayTerm - when present.
943 New YAZ client command, options, that sets Z39.50 options.
945 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
946 options from a string of tokens (one token for each option bit).
948 Update SRW diagnostic code messages.
950 --- 2.0.9-5 2004/01/07 Debian/Windows
952 Handle user defined stylesheet for SRW/SRU.
954 --- 2.0.9-4 2004/01/06 Debian/Windows
956 Fix bug in decoding of Content-Length.
958 --- 2.0.9-3 2004/01/06 Debian/Windows
960 Fix a bug with decoding of XML packed records.
962 --- 2.0.9-2 2004/01/05 Debian only
964 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
966 Fix bug in SRW/SRU diagnostics decoding.
970 Fixed bug in Generic Frontend Server which could drop records exceeding
971 preferred message size. Reported and fixed by Irina Dijour.
973 Fixed calculation of package size for structured records in Generic
974 Frontend Server. Reported and fixed by Irina Dijour.
976 Fixed namespace for SRW/SRU diagnostics.
978 Fixed SEGV in yaz-client that occured for HTTP connection errors.
982 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
983 this version is incompatible with version 1.0 and older YAZ SRW/SRU
986 CQL changes to reflect recent changes to the specification:
987 * Documentation talks about context sets instead of index sets.
988 * Documentation talks about indexes instead of qualifiers.
989 * The CQL-to-PQF transformer's configuration file now uses
990 "index.set.name = <attributes>" instead of the old form
991 "qualifier.set.name = <attributes>". (Both forms are still
992 understood but the latter is deprecated.)
993 * CQL terms with no explicit index specified are now interpreted as
994 cql.serverChoice instead of srw.serverChoice (which of course
995 behaves exactly the same.)
999 MARC conversion can now generate ISO2709 output in another
1000 character set. yaz-marcdump uses this facility if you invoke it
1003 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1004 functions from there can be used from C++.
1006 --- 2.0.6 2003/12/04
1008 Frontend server now transfers memory from decoded packages to stream
1011 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1012 references to show up.
1014 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1015 the ZOOM Abstract API. The older names for the same options are still
1016 also supported for the benefit of old applications.
1018 ZOOM-C supports "implementationId" and "implementationVersion" options
1019 to go along with "implementationName". These allow the user code to
1020 specify identification strings to be sent to servers.
1021 Add OID for the new ExtLite attribute set.
1023 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1024 as requested/supplid by Ere Maijala <ere@atp.fi>
1026 For generic frontend server, reverse the order of
1027 "toolkit-supplied / application-supplied" strings sent as implementationId,
1028 Name and Version. Also, remove the spaces around the slash. This brings
1029 the GFS in line with the behaviour of ZOOM-C on the client side.
1031 Add function ZOOM_scanset_display_term.
1033 yaz-client shows scan displayTerm if present.
1035 Utility yaz-iconv is now installed by default along with the man page
1038 Extend configure check for OpenSSL to use pkg-config where available (such
1041 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1042 server to specify uid/gid/mask for socket using the format
1043 unix:[user=uid,][group=gid,][umask=mask,]file=path
1044 If file= is omitted the existing format is assumed, e.g.
1046 in which case the mask is 0666 (rw for everybody).
1048 Major restructure of YAZ source. All source in libyaz is in src directory.
1049 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1050 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1052 Added man page for utility yaz-marcdump (used to be called marcdump).
1053 yaz-marcdump is installed by 'make install'.
1055 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1056 of incoming package failed.
1058 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1060 Change prototype of odr_perror: add const to message string.
1062 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1064 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1065 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1066 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1067 DNS lookup. There should not be any compatibility problems with this
1068 assuming that blocking=1 or 0 is used.
1070 Fix bad reference in UNIX comstack in function cs_addrstr.
1072 Fix for compilation on AIX.
1074 The generic front-end server (server/seshigh.c) now supports returning
1075 Init diagnostics to the client in User-information-field, in
1076 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1079 --- 2.0.4 2003/09/04
1081 Allow any CQL relation (not just all,any,exact,scr).
1083 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1084 that features the same UI.
1086 Implemented command update0 in YAZ client which is equivalent to
1087 update but uses old of Ext Update ASN.1.
1089 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1090 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1091 Previously no OID was used for this info.
1093 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1094 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1095 returns 'malformed search term' otherwise.
1097 SortResponse member resultCount now set to NULL in sort handler of
1100 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1103 Add three new utility functions for translating OIDs between various
1104 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1105 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1106 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1107 char *oid_to_dotstring(const int *oid, char *oidbuf);
1108 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1110 Reverted modifications for ES Update definition for z_IU0Update
1111 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1112 is back to YAZ 2.0.2.
1114 String value attributes for CCL parser.
1116 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1117 which their FirstSearch server returns in Init responses, sometimes
1118 carrying useful diagnostic information when Init fails. This has the
1119 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1120 "z39.50/oclcui.asn", where its definition is somewhat different from
1121 what OCLC document on their web-site, as required to interoperate with
1124 Support for anonymous authentication in yaz-client. Use the command
1127 * Fix the OID of the Index Data-local "admin" Extended Service from
1128 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1129 the 1000, which indicates a locally-defined OID, was a mistake.
1131 --- 2.0.3 2003/06/20
1133 Fix CCL directive @case handling so that it affects string match for
1134 both CCL keywords and qualifiers.
1136 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1137 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1138 Decoder has been updated with ASN.1 changes as listed in
1139 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1140 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1141 z_IUUpdate, remains unchanged.
1143 ZOOM_record_get may now return a record in a specific character set.
1144 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1145 "from" is the character set of record as returned by target. "to" is
1146 the character set to be returned. If omitted, "to" is UTF-8.
1148 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1150 New ODR utility, odr_getelement, which returns name of element for
1151 which encoding/decoding failed.
1153 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1154 in cases where a required element was omitted.
1156 Bug fix: some MARC8 sequences were not converted.
1158 New ZOOM option "step" which specifies number of records to be
1159 retrieved in one chunk. Used in conjunction with "start" and "count".
1161 SRW support for yaz-client. Use scheme http: to use it, e.g.
1164 yaz-client no longer does (un)intelligent character set conversions
1165 by default. Can be enabled with charset and marc_charset commands.
1167 xmalloc trace fix for 64-bit systems such as DEC alpha.
1169 Solaris 2.6 compile fix.
1171 New function, cql_strerror() translates SRW error codes, as returned
1172 by cql_transform_error(), into human-readable English strings. Used
1173 in yaz-client diagnostics when appropriate.
1175 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1176 converts it into a type-1 query which is sent to the server. This
1177 makes CQL available for use with all Z-servers, as opposed to the tiny
1178 minority that can handle CQL queries themselves.
1180 --- 2.0.2 2003/04/28
1182 New Debian package layout similar to the Redhat Package layout.
1184 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1185 and search result respectively.
1187 --- 2.0.1 2003/04/25
1189 Redhat package is now several packages: libyaz (runtime libraries),
1190 libyaz-devel (development and documentation, and yaz (utility programs).
1191 Package spec file by Morten Bøgeskov.
1193 New member 'schema' in struct bend_fetch_rr which the name of requested
1194 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1195 handler MAY set this to reflect the schema of the returned record.
1197 New member 'display_term' in struct scan_entry. GFS now sets member entries
1198 and allocates scan entries to be filled by user scan handler. In previous
1199 version, entries member was allocated by the scan handler. That still works,
1200 but the GFS will ignore member display_term - assuming it was NOT set by
1201 the handler. The fact that the GFS now allocates the entries both allows
1202 for new members and makes a scan handler easier to write.
1204 Fix CQL lex buffer overflow.
1206 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1207 SRU default recordPacking is string.
1209 SRU protocol support for frontend server.
1211 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1213 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1215 Added scan for the ZOOM shell (zoomsh).
1219 * String Identifers for Schemas (Amendment 5).
1220 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1221 Old definition for schema
1222 Odr_oid *schema; /* OPT */
1227 Z_InternationalString *uri;
1228 #define Z_Schema_oid 1
1229 #define Z_Schema_uri 2
1232 * resultCount parameter to Sort Response (Amendment 1).
1233 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1235 Support for SRW 1.0 over HTTP. This is an optional feature and
1236 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1239 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1240 on the same port. SRW SearchRetrieveRequests are mapped
1241 to bend_init,bend_search,bend_fetch,bend_close.
1243 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1245 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1246 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1248 ZOOM connections are SRW based if schem http is used for hostname
1249 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1250 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1252 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1253 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1254 distance=n, order=true/false, relation=le, prox unit=word. If
1255 n is omitted, distance 1 is used.
1257 Fixed problem with C compiler include path in wrong order.
1259 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1260 on Solaris. Patch from Ko van der Sloot.
1262 New MARC decode API. All new functions operate on a yaz_marc_t
1263 handle. The most important new functions are: yaz_marc_create,
1264 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1265 decode and destroy respectively. Decoder can produce formats
1266 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1267 include/yaz/marcdisp.h.
1269 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1270 to UTF-8, UCS-32, wchar_t or Latin-1.
1272 * Prototypes for yaz_iconv_-functions moved to separate header
1273 include/yaz/yaz-iconv.h.
1275 Make a few private functions 'static' in unix.c. This prevents
1276 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1278 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1279 are set when Init Response is received.
1281 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1282 but returns diagnostic set as well.
1284 New function yaz_strerror which is a portable wrapper for
1285 strerror/strerror_r/GetLastMessage.
1287 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1288 is returned for MARC. If type is "oai", then OAI MARC is returned.
1290 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1293 --- 1.9.2 2002/11/26
1295 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1297 Fix bad race conditions on SIGTERM and terminate gracefully in
1300 Move retrieval (data1) module to Zebra since nobody seems to be
1303 Add GRS-1 render for ZOOM using same format as yaz-client.
1305 --- 1.9.1 2002/10/05
1307 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1309 Fix broken ESpec handling in data1 module.
1311 SGML reader parses comments and makes them part of the data1 tree.
1313 Added several type casts so that YAZ compiles as C++ code.
1315 ZOOM didn't handle PDU encoding failures properly.
1317 Added more Bib-1 diagnostics (approved extensions).
1319 GNU configure: better check for iconv.
1321 More portable use of accept, getpeername. Check for socklen_t. Use
1322 int/size_t if socklen_t is not defined.
1326 PQF parser rejects bad queries - including those with extra
1327 characters in them. PQF parser used to silently ignore that.
1328 Cleaner API for PQF added, which allows you to get detailed
1329 error information for bad queries (see yaz/pquery.h).
1331 Fixed bug in ZOOM_record_get for type "database".
1333 Implemented mini iconv library supporting conversions between
1334 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1336 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1338 --- 1.8.9 2002/08/20
1340 Fixed ZOOM C record cache so that preferredRecordSyntax and
1341 elementSetName is used to check for already fetched records.
1343 --- 1.8.8 2002/08/02
1345 Added three members in bend_initrequest structure to facilitate
1346 character set negotiation.
1348 Fixed a bug in frontend server that could cause indefinite
1349 loops under rare conditions.
1351 Revised character set utilities (charneg.h) so that encoding
1352 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1354 For PQF, directive @term <type> sets term type for Scan/Search.
1355 Here <type> is general, string, numeric, null. The term type
1356 is inherited - just like @attr.
1358 New call odr_set_charset that sets character set conversion for
1359 international-strings on a ODR stream. Prototype is:
1360 int odr_set_charset(ODR o, const char *to, const char *from);
1361 The InternationalString is still represented as C string in YAZ
1362 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1363 won't). On the protocol level, you can use any encoding.
1365 Support for UNIX sockets in ZOOM.
1367 Solaris recv sometimes returns errno == ENOENT. It is treated as
1368 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1370 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1371 both client and server. Code by Morten Bøgeskov.
1373 --- 1.8.7 2002/05/22
1375 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1376 that they can be used directly from Visual Basic. You must recompile
1377 your windows APP if you're using ZOOM.
1379 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1380 Commands "lang" and "charset" sets language and character set respectively.
1381 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1382 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1384 Attributes from multiple CCL fields may be OR'ed rather than merged
1385 using directive "@field or". Fields are still merged by default -
1386 equivalent to "@field merge".
1388 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1391 Fixed bug in zget for parameter ExtendedServicesResponse.
1395 --- 1.8.6 2002/03/25
1397 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1399 Client displays USR.1:SearchResult-1 (hits per term).
1401 Additional Search Info for search in Generic Frontend Server.
1403 Fixed CCL parsing of "field=s".
1405 WIN32 installer - using the excellent NSIS software from nullsoft.
1407 Fixed CCL parsing of "field = - <number>".
1409 Added function yaz_marc_decode that decodes MARC for line mode
1410 display or XML (similar to that used by JZKit).
1412 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1413 Z39.50. But ISO/ILL was, however.
1415 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1416 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1418 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1419 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1421 --- 1.8.5 2002/02/03
1423 New YAZ client features: Command completion and new commands:
1424 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1425 Code provided by Jacob Poulsen.
1427 New call oid_trav, that visits all registered OIDs via callback.
1429 Function ZOOM_record_get now returns const char pointer rather than
1430 void pointer. It saves a lot of type casts.
1432 For YAZ client, command "auth" now allows you to set authentication
1433 in IdPass style. It is enabled when three tokens are given - order
1434 is user, group and password.
1436 Fix memory leaks in MARC record handling for ZOOM.
1438 New option for YAZ client, -k <kilobytes> that sets
1439 maximum record size. Similar to -k option for generic frontend
1440 server and yaz-ztest.
1442 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1444 Prefix query parser reports "fail" when bad attribute set is given.
1446 Fix in MARC decoder. Proximity logging. Fix for attribute set
1447 in scan handler for server. Patches by Shigeru Ishida.
1449 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1452 Configure option --with-openssl=<dir> now works when a directory is
1453 specified. Patch provided by Morten Bøgeskov.
1455 New option for YAZ client, -u <auth>, that sets authentication.
1457 ZOOM fix: error information was sometimes "missing", since error
1458 was cleared/reset too when it shouldn't.
1460 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1462 --- 1.8.4 2002/01/04
1464 Scan for ZOOM API. New object ZOOM_scanset. New functions
1465 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1466 ZOOM_scanset_destroy.
1468 New ZOOM function, ZOOM_connection_last_event, that returns type
1469 of last event (such as "receive data", "send data", "apdu received",
1472 New ZOOM option, schema, that specifies schema for retrieval.
1474 New CCL feature. Qualifiers can be aliases for one or more
1475 other qualifiers (if more than one is given, OR is used).
1477 ZOOM uses named result sets if target supports it.
1479 Two new YAZ client commands: . (dot, which sources a script of YAZ
1480 client commands), and ! (to execute shell command.). Implemented
1483 Working on Debian packages.
1485 --- 1.8.3 2001/11/19
1487 YAZ client enables named result sets only if target supports it.
1489 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1491 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1492 with key="host" to get same result.
1494 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1495 Function Z3950_resultset_record(s) returns references to records
1496 "owned" by resultset. To become owner use Z3950_record_clone.
1498 Function z_ext_record handles Extended Services. Thanks to
1501 --- 1.8.2 2001/11/12
1503 CCL Parser fix: ignore token comma when dealing with and-lists.
1505 Documentation updates for COMSTACK.
1507 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1508 Changed prototype Z3950_records. For some functions, int parameters
1509 were changed to size_t.
1511 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1514 New MARC decode/display function, marc_display_exl, which properly rejects
1515 non-ISO2709 records. YAZ client uses it.
1517 --- 1.8.1 2001/10/29
1519 Fix bug: local attribute set wasn't set correctly in PQF strings.
1523 * Old Z39.50 codecs no longer supported.
1525 Added ZOOM C binding. See http://zoom.z3950.org/
1527 Renamed states for COMSTACKs to avoid confusion with events.
1529 Implemented cs_look and proper cs_rcvconnect.
1531 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1533 Configure detects POSIX threads on OpenBSD.
1535 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1536 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1538 When error is returned from present handler, non-surrogate diagnostic
1539 is returned in present response (and fetch handler is no longer called).
1541 * Minor adjustments to pquery parser (PQF). Token characters may be
1542 escaped by using backslash (C-style).
1544 PQF parser allows string attribute values to be specified. For @attr,
1545 non-numeric characters after the equal-sign are treated as strings
1546 (e.g. @attr 9=title).
1548 CCL trunction character may be defined (@truncation in file)
1550 * function zget_ExtendedServicesRequest sets waitAction to
1551 waitIfPossible (was wait).
1553 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1556 CCL operator names may be set in field definition files (CCL_bibset).
1557 See ccl/bib1 for an example.
1559 Fixes in ASN.1 compiler for C++ compatibility.
1561 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1562 and "op_or" to avoid conflict with C++.
1564 Fixed problem with GNU readline detection on Redhat 7.0.
1566 Added step-size for Scan backend handler.
1568 Fixed bug that made the frontend server crash when no attribute
1569 set was specified for scan.
1571 Front-end server automatically switches to original working directory
1572 when installed as an NT service. Previously -w had to be specified to
1575 Added extended attributes for retrieval module (data1), so that data1
1576 records carry d1_readXML/SGML attributes. d1_read also supports
1577 null-data rules ( <tag/>)
1579 On UNIX when POSIX threads are available, a separate library libyazthread
1580 is created. Programmers should link with that library and the yaz library
1581 when using threads. The reason for the split was that some applications
1582 on Linux, such as Apache, doesn't work well when using shared objects that
1585 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1586 (or any frontend server) in SSL mode by specifying ssl: followed by
1587 address. Only tested on UNIX.
1589 Added feature for CCL module. Virtual structure s=al or s=ol generates
1590 and-list and or-list respectively instead of phrase search.
1594 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1595 log_mask_str. This was done to avoid name conflicts with other libraries
1596 (such as other PHP extensions).
1598 Added raw OID member for preferred record syntax (request_format_raw)
1599 and returned record syntax (output_format_raw) for backend fetch method.
1601 Config file yaz-config now accepts options so that it returns specific
1602 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1604 Shared library support for UNIX using GNU libtool.
1606 * Modified backend interface. Request/Response struct's replaced by
1607 one read/write C struct. For example bend_fetchrequest and
1608 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1609 Every handler - even search has to be registered in bend_init
1610 handler. This means that the YAZ library no longer refers to
1611 external functions and it makes it possible to make the whole
1612 thing a single DLL/SO.
1614 Added Segment handler for backend server.
1616 Added Zmbol/Zebra administrative functions to YAZ client.
1618 Threaded frontend server on UNIX (when POSIX Threads are available).
1619 Starting the server with option -T enables multi-threading.
1623 Added configure option --enable-comp/disable-comp to control use
1624 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1625 located in sub directory asn.
1627 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1628 in ${exec_prefix}/bin along with the other programs yaz-client and
1631 GNU automake used to maintain makefiles.
1633 Added several OID's.
1635 Changed retrieval module so that we can load records with no abstract
1636 syntax defined. Tagpaths in these records are fully composed of string
1639 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1643 On UNIX, the generated makefile now supports a proper 'make install'.
1644 The prefix can be set via GNU configure to set the install location
1645 (default is /usr/local).
1647 * YAZ programs client and ztest were renamed to yaz-client and
1648 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1649 locations, such as /usr/bin,/usr/local/bin,etc.
1651 * YAZ Header files were moved from include to include/yaz. YAZ Header
1652 files are referred to as include <yaz/log.h> rather than <log.h>.
1653 The YAZ include path (-I ..) is therefore the same as before. Programmers
1654 should update their #include statements or use -Ipath/include/yaz
1655 instead. The main motivation for doing this change is that YAZ header files
1656 can be installed in "standard" locations /usr/include,/usr/local/include
1657 without introducing conflicts, since ALL YAZ header files are stored
1658 in subdirectory yaz (under /usr/include for example).
1660 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1661 rather than project/workspace files. We switched because project files
1662 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1665 Changed name of logging function, logf, to yaz_log, to prevent name
1666 clash with some math-log functions. The YAZ header log.h defines logf
1667 to yaz_log (#define) so there should be no incompatibilities by this
1670 Added bend_start/bend_stop handlers for server. These handler are
1671 called on start/stop of server. For windows they are called whenever
1672 a service is started/stopped.
1674 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1675 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1676 in util/yc.tcl. The auto-generated C code structures are, in a few
1677 cases, incompatible with the old decoders. There are differences in the
1678 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1679 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1680 The preprocessor variable ASN_COMPILED is defined when the compiled
1681 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1682 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1683 wish to use the old encoders/decoders you can specify --disable-yc
1686 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1687 version so that it supports both new - and old version of DB Update
1689 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1690 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1691 change. The name parameter can be set to 0 in which no name is specified
1692 for the construction. The macros odr_implicit and odr_explicit sets name
1693 parameter to zero for the construction involved. New macros
1694 odr_implicit_tag and odr_explicit_tag are similar to the others,
1695 except that a name parameter is added. For programmers' that don't use
1696 ODR they probably only need to change the call to z_APDU and z_External.
1698 Added access control facility by interfacing the TCP wrapper library.
1699 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1700 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1701 name of the daemon and enables the access control as specified in
1702 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1704 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1705 den Dool <H.M.vdnDool@kub.nl>.
1707 Added reference ID parameter to most functions in server API - refer
1708 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1710 Changed name of ccl library to libccl.a (was ccl.a).
1712 Fixed bug in decoder for Explain (Category TargetInfo).
1714 Added support for GNU readline in client. Thanks to Jacob Poulsen
1715 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1717 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1718 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1719 IMPLEMENTATION! This change was made to the development version before
1720 the ZIG decided to retract the amendment. If any users MUST be
1721 compatible with the original Update definition, PLEASE CONTACT US, and
1722 we will include a separate definition corresponding to the old Update
1723 ES. Note that because of the change to the ASN.1 of the
1724 TaskPackageRecordStructure we cannot define a single structure that
1725 will support both versions.
1727 * Added const modifier to buffer parameter for some ODR/BER encoding
1728 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1729 completeWAIS, odr_dumpBER.
1731 Fixed bug in client.c which caused a crash when a scanResponse didn't
1732 contain positionOfTerm.
1734 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1735 * will cause an error in a client if a non-YAZ target sends both a
1736 * list of Scan entries and non-surrogate diagnostics.
1738 Retrieval module enhancements. Tag sets may be typed in the reference
1739 to it. From the .abs-file the "tagset" directive takes a third optional
1740 integer type for the tag set referenced. From a .tag-file the "include"
1741 directive takes a third optional type as well. The old "type" directive
1742 in the tag set itself is still recognized but acts as the default type
1745 Backend interface change. Individual Scan terms returned from bend_scan
1746 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1747 in include/backend.h.
1749 Retrieval module enhancements. Multiple tag sets and attribute sets may
1750 be specified in abstract syntax specs. Revised the error/warning for
1751 logging messages reported by the retrieval module when reading the
1754 Object Identifier system (oid_..) changed. The API is backwards
1755 compatible but the oid-routines now allocates new OID's when needed.
1756 Raw OID's may be specified in oid_getvalbyname.
1758 YAZ now uses GNU configure to generate Makefile(s).
1760 * Minor changes in some of the member names of DeleteResultSetRequest and
1761 DeleteResultSetResponse. See include/proto.h.
1763 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1764 and added member 'languages' in TargetInfo (which was missing).
1766 Changed the way attribute sets are handled in the retrieval
1767 module. These are now cached, just like the abstract syntaxes
1770 Changed YAZ so that it links with compiled ASN.1.
1772 Added Explain-schema definitions and mapping routines. The following
1773 Explain categories have been implemented: AttributeDetails,
1774 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1776 Fixed minor bug in Windows version of Server Library.
1778 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1780 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1782 Added EXTERNAL: UNIverse Resource Report (non-standard).
1784 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1785 ENUMERATED and SET OF.
1787 * Added 'const' to some of the char pointer arguments for the
1788 functions, data1_read_node, data1_getelementbytagname,
1789 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1792 Fixed bug in data1_insert_taggeddata - the last_child member of
1793 parent wasn't initialised.
1795 * Changed data1_read_record and data1_read_node so that the supplied
1796 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1797 doesn't refer to any parts of the "SGML"-buffer.
1799 Fixed bug in server library (Windows version of statserv_remove).
1801 * Changed code so that it compiles as C++. The type definition
1802 of Odr_fun which is a member of Odr_arm was changed. The result is,
1803 that an explicit typecast is needed for the fun pointer when
1804 using Odr_arm - as in:
1805 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1807 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1809 Implemented the new structured date and time definition as approved
1810 by the ZIG. Added schemaId element to the specificTag in Espec-1
1811 (also approved at the last ZIG). Thanks to RVDM.
1813 Added some Object identifiers (RVDM).
1815 Changed the Update Extended Service (RVDM).
1817 Added command "refid" to client which specifies referenceId for
1818 the following requests.
1820 Implemented extended service handling for server. See ztest.c
1821 for an example as well as backend.h. New handlers are registerd
1822 in the Init handler.
1824 * Changed interface for sort in server.
1826 Added new members to statserv_options_block. It allows a server
1827 to read options from another source than just the command line. Thanks
1828 to Charles Woodfield.
1830 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1831 renamed to zboolean. Some C++ compilers complained about the name.
1833 Minor changes to gils.abs. Added index 's' (sort) on title
1834 and date/time-last-modified.
1836 --- 1.4pl2 1998/1/30
1838 Fixed bug in server library regarding inetd mode (-i). This bug
1839 was introduced by release 1.4.
1841 --- 1.4pl1 1998/1/29
1843 Added sort facility in client and backend server interface.
1845 Fixed problem with dependencies in Makefile(s).
1847 Fixed bugs for encoders/decoders of extended services and
1850 Implemented sub-tree feature for schemas. Sub-trees are
1851 referenced in *.abs-files. See explain.abs for an example
1852 of the use of this feature.
1854 Modified bib1.att; local attributes for ANY didn't include
1855 ANY itself (only affects use of the retrieval module).
1857 Fixed bug in plain SGML reader in function data1_read_node:
1858 tags with prefix "var" was incorrectly interpreted as variants.
1860 Added feature "sub-schemas" to enable references to - and definitions
1861 of - group of elements.
1863 * Removed member parent from type data1_element (in data1.h).
1865 Implemented function odr_nullval() that returns the value of
1868 * Removed member num_children from data1_node (in data1.h).
1870 Made NT service interface part of the server library. The
1871 function statserv_main uses the NT service when required and
1872 calls the statserv_start / statserv_close routines.
1874 Routine zget_SearchRequest and zget_PresentRequest fills
1875 resultSetName/Id member with "default" instead of "Default".
1877 Fixed memory leak in server. Request queue member wasn't freed.
1879 Fixed nmem_exit so that memory is freed.
1883 Revised the CCL parser utility to be thread safe.
1885 Added function, oid_ent_to_oid, to replace the function
1886 oid_getoidbyent, which is not thread safe.
1888 * Added nmem_init and nmem_exit to initialize and release
1889 NMEM resources. Function nmem_init should be called once in the
1890 initial thread before NMEM/ODR is used. statserv.c and client.c
1891 have been changed accordingly. The change was necessary to make
1892 NMEM thread safe. The NMEM memory pool is shared amongst threads
1893 in a process. Unix-based applications will still work fine without
1896 Added NT Services interface for the the Z39.50 (statserv) Server.
1897 Refer to the ztest.c source on the usage.
1899 Windows 95/NT port using MSVC5.0. Project files are included in the
1902 * Defined new 'global' handle for the retrieval (data1) system. The
1903 new handled, data1_handle, describes the state of the data1 system.
1904 This handle is passed as first argument to virtually all
1905 data1 related routines. The functions data1_create and data1_destroy
1906 creates and destroys a data1 handle respectively.
1908 Added ODR encode stream member to all backend request structures
1909 init, search, scan etc. This stream should be used to allocate all
1910 memory used for the response when thread safe operation is needed.
1912 Changed the comstack utility, cs_addstr, to be thread safe. The
1913 returned hostname string returned by the function is now part the
1916 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1917 function. The cs_straddr takes a COMSTACK handle as argument, so this
1918 function must be used after cs_create and before bind/connect.
1919 This function is thread safe.
1921 Moved test server to 'ztest' directory - generic server code still
1922 in 'server' directory.
1924 Made prefix query (pquery.c) utility thread safe.
1926 Added new function modifier YAZ_EXPORT to 'export' public DLL
1927 functions when using windows (see include/yconfig.h).
1929 Added definitions to the OID database (util/oid.c) (RVDM).
1931 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1933 Added call to ccl_rpn_delete in client program.
1935 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1936 release of RPN structure.
1938 Added support for C++, headers uses extern "C" for public definitions.
1939 With input from RVDM.
1941 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1942 Thanks to Ronald van der Meer (RVDM).
1944 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1946 Added support for private extensions to the OID database
1947 (oid_setprivateoids()). Thanks to RVDM.
1949 Added optional, physical ANY (key replication)
1951 Fixed null-reference problem in GRS-1 output filter.
1953 Proximity operator added to Prefix Query Format (PQF).
1955 In test client command "base" accepts multiple databases.
1957 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1961 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1963 Smallish bug-fixes in the new encoders/decoders (explain).
1965 Bug fixed in DeleteRequest.
1967 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1969 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1971 Added SOIF syntax (using private OID for now) to retrieval module and client.
1973 Added Update extended service.
1975 Added SearchResult-1 additional info structure.
1977 Added optional CCL (ISO8777) interpreter as separate module. Available
1980 --- 1.2 1996/6/10 (1st anniversary release)
1982 Added Summary record syntax. Lightly tested.
1984 Added OPAC record syntax. Untested.
1986 Added ResourceReport service encoders/decoders. Untested.
1988 Fixed bug in z_Unit - wrong tagging on unitSystem.
1990 Fixed bug in the DiagRecs decoder.
1992 Added options for max PDU size and session timeout to frontend-server.
1994 Added documentation of query-language parsers and other supporting utilities.
1996 [frontend-server] Added Attribute set to the bend_scanrequest API.
1998 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1999 surrogate diagnostics were generated.
2001 [retrieval] Allow multiple local values for attribute.
2003 [retrieval] Allow multiple attributes per element in .abs files. index type.
2005 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2007 --- 1.1pl2 1996/4/10
2009 Minor changes, mostly specific to Zebra's requirements (retrieval)
2013 Repaired bug in frontend server when running multiple listening
2014 endpoints in dynamic mode.
2016 z_External() now won't break if a known, ASN.1 value comes encapsulated
2017 in an octet-string. The value will pass through unmodified in an Odr_oct.
2019 Added a bit of code to the demo client to decode & display
2020 ASN.1-structured records represented in the octet-aligned branch of
2021 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2023 Added z_ext_getentbyref() to the ASN module. Doc updated.
2025 * Completed the SCAN definition in the ASN module. This may break SCAN
2026 code based on older YAZ-versions at compile-time. The fix is easy -
2029 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2030 under the SCAN definition. Remember to initialize this, server-people.
2032 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2033 that this does not extend to ODR and ASN.
2035 Comstack allows insertion of established socket (primarily for
2036 inetd-operation of servers). Doc updated.
2038 Front-end server can now start from the inetd in TCP mode. Doc
2041 --- 1.0pl4 1996/1/24
2045 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2046 the rank and record number.
2048 Adjustments to the frontend server.
2050 Fixed diagnostic BER dumper. It ignored the file argument.
2054 Various changes to retrieval module.
2056 Changed the union discriminators of the protocol files from enums to
2057 ints paired with #defines.
2059 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2062 *Changed operator in the RPN structure to 'roperator', again to avoid a
2065 Fixed problems in Explain decoders/encoders.
2067 --- 1.0pl2 1995/12/6
2069 Memory bug in log module fixed.
2071 --- 1.0pl1 1995/12/5
2073 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2075 Bug in Explain DatabaseInfo module fixed.
2077 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2081 The shift to v1.0 signals that we now consider the *core* functionality
2082 of YAZ reasonably stable (the core being more or less equivalent to
2083 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2084 tested (Explain not at all - though that will happen soonish).
2086 Minor changes to code to support Windows port.
2088 Various minor changes after we're getting to use GRS-1 & co. more.
2090 Added Espec-1 format.
2092 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2093 of the protocol and it cannot be selected when encoding (maps into 'string'
2094 when decoding). Needed to talk to some servers.
2096 Demo client can request simple element set names.
2098 Added Diagnostic Format encoders/decoders.
2100 Added simple Close handling to frontend server (no hooks for resource
2101 reporting yet), and demonstration client.
2103 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2105 --- 1.0b3 1995/08/24
2107 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2108 handled incorrectly when records were requested in the searchResponse. This
2109 will only affect you if you use the frontend-server.
2111 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2112 Test-client will ask for and print GRS1. Ztest will return dummy records
2115 Added Explain encoders/decoders to the service-level API. Untested.
2117 Added Extended Services: Item Order encoders and decoders to the Service-
2118 level API. Untested. We could use a recent copy of the pertinent bits
2119 of the ILL protocol to add those bits.
2121 Added diagnostic format 1 encoders/decoders to the service-level API.
2124 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2125 odr_cons.c, which causes a more correct output.
2127 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2128 was always set to 0 when no records were requested in the searchRequest.
2130 * Added better external-handling. This shouldn't harm old code that
2131 *encodes* externals. It can break code that looks for a
2132 'single-ASN1-type' representation, since those types that are known
2133 are now decoded immediately. Look at the SUTRS sample code in
2134 seshigh.c and client.c. Documentation updated.
2136 Handling of structured records in bend_fetchresponse. Length -1 marks
2137 structured record, type is deduced from format field.
2139 --- 1.0b2 1995/06/27
2140 Fairly quick maintenance release to add SUTRS support.
2142 Fixed handling of SUTRS records in the demonstration client.
2144 * Added format field to the bend_fetchrequest and bend_fetchresponce
2145 structures of the backend API (frontend server). When the record is
2146 returned, the value of the format field is mapped to an OID. The
2147 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2148 of the record. The special value VAL_NONE in the bend_request means
2149 that no specific format was requested by the client. Documentation
2150 updated accordingly. Test server (ztest) will return a fixed dummy
2151 SUTRS record if your client requests SUTRS.
2153 Documentation updated accordingly.
2155 You can now set external libraries and RANLIB support in the top-level
2159 First public release.
