3 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
5 For OID class, use oid_class consistently.
7 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
10 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
11 character set for bibliographic information interchange". By Giannis Kosmas.
13 Added documentation on new OID API.
17 Changes to generic frontend server interface: added new member
18 'query_charset' for bend_initrequest structure. A backend init handler
19 should set this member to its native character set for query terms.
20 When defined, the frontend server logic will announce this character set
21 to a client if the negotiationModel bit is set by the client. All server
22 implementors are encouraged to specify this. If a backend server does not
23 specify this a warning is issued using yaz_log(YLOG_WARN,..).
25 Added CCL utility to remove terms (stop words) from resulting RPN
26 tree. This is handled by functions with prefix ccl_stop_words_ .
28 New ZOOM C option, "rpnCharset", which allows client-side conversion of
31 Clean-up the CCL API. Moved some internal structures from ccl.h to
32 private header cclp.h. Changed ccl_parser_create so that a Bibset must
33 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
34 This is replaced by ccl_parser_find_str which takes a string instead.
36 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
37 libyaz.la is the core of YAZ except the generic frontend server and
38 does not depend on POSIX threads anymore. libyaz_server.la is the
39 generic frontend server facilities and uses POSIX thread functionality
40 if available. The libyaz.la no longer depends on POSIX threads because
41 the number of global structures is limited. NMEM no longer re-uses blocks
42 between threads ; it simply free's memory immediately but allocates in
43 "large" chunks as usual. We don't expect any performance penalties
44 because of this. The yaz_log system is still using a global log_level so
45 caution must be taken when modifying it with yaz_log_init_.. +
46 yaz_log_mask_str. This, however, should not cause any trouble because
47 these functions are called during initialization of application code
48 anyway. `yaz-config --libs server` returns libs for server applications;
49 `yaz-config --libs` returns libs for non-server applications.
51 New OID database - with public definitions in oid_db.h. Removed old OID
52 database including the head oid.h and definitions such as enum oid_value
53 and struct oident. The new OID database uses the same string names as
54 before but the 'protocol' is gone. There are now only two representations
55 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
56 converts from string to OID; functions with prefix yaz_oid_to_string
57 converts the other way.
59 Change to emit_term() in CQL-to-PQF query translation: when a term has
60 the /regexp relation modifier, do not process it for leading and
61 trailing "^" and "*", which have quite different meanings in regular
64 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
65 write handlers no longer carries a 'last' parameter. This will make
66 yaz_iconv flush "less" characters. A flush is performed by call to
67 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
69 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
70 removed, because function yaz_query_to_wrbuf does the same.
72 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
73 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
75 Deprecated MARC utility functions removed.
77 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
80 Branch split: YAZ_2_1_55_branch
84 Fix to ZOOM-C so that transparent reconnection is properly handled on
85 connections that are in asynchronous mode.
87 Fixed compilation on OpenBSD 4.0.
89 Large strings in GRS-1 records are now properly displayed in yaz-client.
91 Added character conversion support for "advancegreek"; based on patch from
94 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
95 sequence is met. Before the error was not set so it would be unknown.
97 Adjust yaz-marcdump MARC reader so that it skips until record separator
100 --- 2.1.52 2007/03/07
102 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
103 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
104 fd_set structure used as a bitmask for the FDs to be selected on.
106 Using ACX_PTHREAD macro to check for POSIX threads.
108 Fixed have-vsnprintf check.
110 --- 2.1.50 2007/02/23
112 Fixes for configure on BSD. Bug #900.
114 Added snprintf/vsnprintf wrappers for systems that don't have
115 limits (heavens forbid).
117 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
118 created before all previous tasks were completed and removed from the
119 task queue, the new task could be removed by a mistake.
121 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
123 Implemented pass-through CQL-to-PQF conversions. Bug #861.
125 Fixed bug #832: Problem with MARC/charset in yaz-client.
127 Fixed bug #668: save command line history for yaz-client.
129 Fixed bug #830: pkg-config support.
131 --- 2.1.48 2007/01/23
133 Extended ZOOM result set options with two options that may be read by
134 a client: resultSetStatus and presentStatus with values as specified for
136 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
138 Fixed bug #827: Using SSL fails on Debian etch.
140 Fixed bug #826: Weird looking chars for set of MARC records.
142 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
143 that is treated as an ItemOrder with itemRequest being an XML document
144 external. The value of "doc" is the content.
146 Extended the GFS search facility. New member of bend_search_rr
147 'estimated_hit_count' signals that hits is known to be an estmate
148 (higher or lower than real hit count). New member 'partial_resultset'
149 signals that the search was partial (hit count is lower or equal than
150 real hit count). For Z39.50, the information is stored in resultSetStatus
151 member of SearchResponse APDU. For SRU, the information is signalled
152 via SRU diagnostic 59: "Result set created with valid partial results
155 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
157 --- 2.1.46 2007/01/13
159 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
161 Added ZOOM_connection_peek_event.
163 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
164 the following new functions:
165 ZOOM_event_nonblock, ZOOM_connection_process,
166 ZOOM_connection_get_{socket,mask,timeout},
167 ZOOM_connection_fire_event_{timeout,socket}.
168 The existing blocking event handler, ZOOM_event, is a wrapper for the
169 + blocking ZOOM_event_sys_{poll,select}.
171 Implemented function ccl_xml_config which parses XML version of CCL
172 configuration (bug #798).
174 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
176 Added timings utility (yaz/timing.h)
178 --- 2.1.44 2007/01/03
180 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
183 Fixed bug #779: Rotation of apdu.log fails.
185 Fixed for character set conversions:
186 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
187 Honor G1 set in MARC-8 decoding.
189 --- 2.1.42 2006/12/17
191 Fixed bug #775: char conversion does not handle Alternative UTF-8
194 Implemented function yaz_marc_read_line which parses MARC line format
195 records. There is a wealth of formats out there. So far, this function
196 reads line records produced by yaz_marc_write_line.
198 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
199 more generic and easier to remember(!) options: -i format and -o format
200 which specifies input format and output format respectively - where
201 format is one of "marc", "marcxml", "line", "marcxchange".
203 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
204 does not print anything except warnings for records.
206 For yaz-marcdump, added support for MARC split into files (-s) with a given
209 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
210 spec, at http://www.loc.gov/standards/sru/record-update/
211 This has changed the binary layout of the following structs:
212 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
213 bend_update_rr . Patch by Ko van der Sloot.
215 Added GFS utility function bend_assoc_is_alive which returns 1 if
216 association is still alive (client is connected); 0 otherwise (client
217 closed connection). This allows busy servers to stop working for
220 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
221 been a separate piece of software. This version of ziffy has been modified
222 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
224 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
226 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
227 Client code may now interrogate options such as "init_opt_sort" to
228 find out whether the server claims to support various options.
230 --- 2.1.40 2006/11/27
232 Added utilities yaz_{set,get}_esn to set/get element set name from
235 Removed the build of libyazthread.la. The libyaz.so is the threaded version
236 of YAZ and has been so since YAZ 2.1.10.
238 Implemented ZOOM_record_error which returns error information for
239 record (surrogate diagnostic).
241 --- 2.1.38 2006/10/31
243 Updates for SRU Update by Ko van der Sloot:
244 1. Changed name from "operation" to "action"
245 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
246 versions in the code, marked as 'backward compatible'.
247 3. Added diagnostics for SRU Update.
249 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
251 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
253 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
255 For GFS, fixed problem with SRU diagnostic 'First record position out of
256 range' being issued for 0 hits.
258 zoomtst10 part of Windows Build.
260 --- 2.1.36 2006/10/13
262 Implemented yaz_filepath_comp which splits a path into file path
263 components (required by Zebra 2.0.3+).
265 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
266 BSD inspired license until now so this should not have any real impact on
267 anybody. See http://www.opensource.org/licenses/bsd-license.php
269 Fixed bug #687: Missing log lines.
271 Fixed bug #678: CQL to PQF translation does not preserve double-quote
274 Fixed bug #689: SRU diagnostics to be added.
276 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
277 whether a connection is idle (no more work do do).
279 --- 2.1.34 2006/10/04
281 Change type of optval from long to int for invocation of setsockopt with
282 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
284 Added support for specifying the max log file size for the Generic
285 Frontend Server. The size is given with option -r.
287 --- 2.1.32 2006/09/21
289 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
291 --- 2.1.30 2006/09/17
293 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
296 Fixed bug in Generic Frontend Server that could cause a server to stop
297 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
299 For the generic frontend server, the maximum record size is used as maximum
300 size of incoming packages (SRU + Z39.50). The value until was previously
301 only used in Z39.50 Init negotiation and, later, in a session controlled
302 sizes of records returned. This is controlled using -k option. It can be
303 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
305 --- 2.1.28 2006/09/04
307 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
310 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
312 New option for yaz-marcdump -lpos=value which allows setting a portion
313 of MARC header to a certain value.
315 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
317 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
318 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
320 --- 2.1.26 2006/08/15
322 Fixed problem with SRU mode type (soap, get, post) for yaz-client
325 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
327 --- 2.1.24 2006/08/08
329 Fixed MARC ISO2709 encoding routines to deal with character set
332 Minor changes to GFS logging. Database included in search request log
335 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
336 cached/multiple records.
338 Shared libraries are built by default on Unix+configure.
340 Changed cql2pqf transformation to use a different evaluation order. The
341 new order is: always, relation, structure, position, truncation, index
342 and relationModifier. Old order was: always, relation, relationModifier,
343 structure, index, position, truncation. Note that the the latter ones
344 override former ones for identical attributes.. The new scheme means that
345 it is possible to override any existing attribute with a relationModifier.
346 And also that it is possible to override everything for the index rule
347 (except the ones listed in relationModifier). No order is perfect but this
348 one, we believe, covers more real cases.. The "always" should have been
349 called "default", since the attributes there can be overridden with all
352 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
353 compilation phase, but also for yaz-config --cflags output. This allows
354 us to have public headers with Libxml2 stuff in them . It should also,
355 eventually, make Libxml2 checks redundant in packages using YAZ, such
358 --- 2.1.22 2006/06/15
360 Changed SRU update structure bend_update_rr so that SRU diagnostics are
361 stored in uri, message and details.. Previously diagnostics were stored
362 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
363 compatibility.. but he's probably the only one affected, so.
365 Added support for CCL, compiled on the client side, in ZOOM-C. This
366 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
367 input; the resulting query objects can be used for for searching with
368 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
370 YAZ' configure searches for OpenSSL by default.
372 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
373 SL_CTX_use_certificate_file. See
374 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
375 for more info. Thanks to Ko van der Sloot.
377 --- 2.1.20 2006/06/02
379 Bug #600: SRU GET, POST support for yaz-client. Introduced
380 command 'sru' which selects method SOAP/GET/POST.
382 Allow missingValueAction to be specified for the sortspec string -
383 function yaz_sort_spec. By default, the missing value action is null.
384 Use ! to specify "abort". Use = followed by stringvalue to specify default
387 Ensured that Present-handler (if defined) is called in GFS before any call to
388 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
389 searchRetrieve requests.
391 Documentation for YAZ is now based on the Docbook XML/XSLT using
392 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
393 is no longer depending on jade/openjade or docbook-to-man scripts.
394 PDF is no longer part of the distribution - but can optionally be
395 made using DSSSL/jadetex or FOP.
397 Added retrieval handling support in Generic Frontend Server to support
398 conversion between MARC/XML as well as XSLTtransforms. See
399 etc/yazgfs.xml for an example.
401 Added Authentication support to Generic Frontend Server in SRU
402 mode. Authentication using HTTP Basic is supported, as is the use
403 of 'x-username' and 'x-password' parameters in the request itself.
405 Added support for a new character set MARC8s identical to MARC8 except
406 that it converts combined characters to single Unicode characters in the
407 Latin-1 range (when possible).
409 --- 2.1.18 2006/04/24
411 ASN.1 compiler 0.4: generates brief Doxygen file header for
412 generated .h/.c files.
414 Utility yaz_iconv now supports conversion to MARC-8.
416 New facilities for the MARC module. The reading - and writing of
417 content are separate methods for the yaz_marc_t handle. The following
418 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
419 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
420 format). Write functions have prefix yaz_marc_write_.. The existing
421 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
422 available. Removed support for OAI-MARC and simplexml (not the
423 simplexml from PHP5).
425 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
426 to be returned for this connection.
428 --- 2.1.16 2006/03/31
430 Allow multiple languages and charsets to be specified with
431 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
432 negcharset iso-8859-1,utf-8
434 Translation of proximity nodes from CQL into PQF now works.
436 Moved to automake 1.8, 1.9.
438 Added function yaz_log_set_handler which allows a log handler to be
439 installed. This handler will be called for all log messages. Output
440 to file is also produced; but that can be disabled by passing NULL
441 fname to yaz_log_init_file.
443 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
445 For SRW (including GFS), accept application/soap+xml as content-type
448 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
449 produces NO stylesheet reference even if a default stylesheet is specified
452 --- 2.1.14 2006/03/14
454 Updated Windows package to include yazd.dll + yazd.lib for the
455 Development component.
457 If the environment variable YAZ_LOG is set, then it is used as a
458 string indicating the default level of logging to use if not
459 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
460 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
461 used as before. So, for example, to omit warnings from YAZ logging,
464 cql_transform() now map structure and other attributes before indexes,
465 so that index-specific structures and other attributes can override
466 defaults. So now a combination of mapping specifications such as:
468 index.dc.date = 1=date-modified 4=5
469 does the right thing.
471 cql_transform() now also respects the "always" mapping specification,
472 which establishes an initial set of attributes to be used for all
473 terms except where overridden by more specific attributes associated
474 with the index, relation or modifier.
476 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
477 which mode to use; one of "post", "get" or "soap" (SRW, default).
479 Fixes for yaz_iconv routines: changed trie-based character set conversions
480 to use only non-negative values for bit fields due to Sun's C compiler not
481 supporting negative values.
483 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
484 sequences where not read correctly. Fix by Rustam Usmanov.
486 Updated win/makefile to use options, settings which makes things
487 compile with VS C 2005.
489 --- 2.1.12 2006/02/01
491 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
493 In ZOOM socket code, use select instead of poll on MacOSX.
495 ZOOM-C now support client-side compilation of CQL into RPN that is
496 sent to the server, enabling CQL to be used against all Z39.50
497 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
498 ZOOM_query object, and submit it using ZOOM_connection_search().
499 The CQL-to-RPN translation uses a configuration file, the name of
500 which must be specified in the Connection's "cqlfile" option.
502 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
503 function, which takes as its start-term parameter a ZOOM_query object
504 (which may have had either CQL or RPN set into it).
507 --- 2.1.10 2005/11/29
509 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
510 GFS to support this as well. Backend handler, bend_srw_update, does the
511 update work. Code contributed by Ko van der Sloot.
513 Allow retrieval of Search Result-1 information in ZOOM by the use of
514 options that are attached to a result set. ZOOM documentation updated
517 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
518 UTF-8 conversion. Patch by Raj Patel.
520 Added option -m to GFS to control formatting of timestamps in log file.
522 Added 'exit' as synonym for 'quit' in yaz-client
524 Added support for specifying SRW resultSetId + resultSetIdleTime in a
525 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
526 for the new members. Patch by Ko van der Sloot.
528 Added support for SRU POST. It is supported for content-type
529 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
531 Do not build the separate Multi-threaded (MT) library libyazthread.la.
532 Instead make the library libyaz.la multi-threaded. Threading as a whole
533 can still be disabled by configure option --disable-threads. Previosly,
534 with older GLIBCs there were problems with MT libs under Apache. This
535 has now been fixed a long time ago.
537 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
540 CQL module modified to be case insensitive for relations/indexes/operations.
542 Fixed bug in CQL transform code: incorrect value relationModifieder
545 Added 'show all' command for yaz-client which retrieves all results
548 Added new yaz-client, xmles, which takes a (private) OID and
549 a document to be sent as an extended service request.
551 Describe new yaz-client commands wait_response and set_auto_wait.
553 Increase TCP/IP listener backlog from 3 (which I am guessing was
554 copied from the SunOS manual entry way back when) so SOMAXCONN, so
555 that the socket will queue as many incoming connections as it's able
556 to handle ongoing connections. In other words, it will never now
557 refuse a connection that it would be able to handle merely because
558 it's not got around to accepting() enough of the pending connections
559 yet. This is the behaviour anyway under Linux, where the listen()
560 argument is ignored; but not under BSD and on systems such as
561 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
562 YAZ-based servers should now be uniform across operating systems in
565 yaz-marcdump uses 64-bit file access on some systems. This is enabled
566 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
567 This allows yaz-marcdump to read large MARC batches (>2 GB).
569 Modified all YAZ source files - except the source which is auto-generated
570 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
573 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
574 corresponding to the existing *_setl() function. These allow option
575 values containing arbitrary valuues.
577 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
578 ZOOM_resultset_sort() in new applications. Its behaviour is identical
579 except that it returns an indicator of whether or not the sort
580 criterion was accepted (0 for OK, -1 for invalid).
584 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
585 MARC output rather than returning "new" buffer.
587 yaz-client warns about unknown init options.
589 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
593 Added support for SRW sort in Generic Frontend Server. Patch
594 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
595 sortKeys - or NULL if none is provided.
597 Fixed bug #307: It was impossible to specify indefinite/no timeout
598 for ZOOM_event. Special timeout value -1 now means indefinite timeout
601 Added support for multiple languages and charsets to be specified in
602 ZOOM. Each charset/language is separated by a blank. If negotiation is
603 in effect in init-response, Option
604 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
605 Code based on patch by Vasiliy Osadchuk.
607 Fixed bug #306: infinite recursion that occurred when calling
608 yaz_log_level_init as the first call (before other log level or
611 Fixed bug in scan handling in front end server: if preferred-Position-In-
612 Response was non-present, a NULL pointer referece was performed.
616 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
617 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
618 now defined for all those error codes. So instead of putting 109 in
619 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
620 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
622 Modified the yaz-marcdump utility to skip garbage bytes between MARC
625 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
627 Program yaz-client now exits and produces an error message if multiple
628 Z39.50 servers are specified on the command line (none or one allowed
631 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
636 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
638 Fixed bug #272: Preserve spacing for CCL terms.
642 Added support for virtual hosts and multiple backend servers for
643 the YAZ frontend server. The configution is XML based and
644 support specificition of CQL to RPN mappings and explain information.
645 See section "Virtual Hosts" in the YAZ manual.
647 Extended OPAC display utility. OPAC display utility renders
648 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
649 to supplement yaz_marc_decode_wrbuf.
651 Fixed a bug in MARC decoder that could caused it to crash for some
652 invalid MARC records. More diagnostics and warnings where added in
653 XML output (warnings, etc are stored in comments).
655 --- 2.0.34 2005/02/08
657 Fixes for UNIX domain sockets. Bug #261.
659 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
661 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
662 Added yaz_marc_subfield_str which defines subfield lead string which is
663 used in YAZ_MARC_LINE format. Default string is blank+$. Added
664 yaz_marc_endline_str which defines end of fields string used in
665 YAZ_MARC_LINE format. Default string is newline.
667 Experimental support for MarcXChange. This format can be produced
668 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
669 http://www.bs.dk/standards/MarcXchange.xsd
671 Added yaz-client commands scansize that sets maximum number of
672 entries to be returned by scan.
674 --- 2.0.32 2005/01/11
676 Added support for SRW scan in yaz-client and Generic Frontend Server.
678 * Added whereInList member to SRW Scan Term.
680 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
682 Fixed NMEM system to return aligned blocks on the smallest boundaries
683 that are suitably aligned for all possible types on the particular
684 architecture YAZ is being built for.
686 --- 2.0.30 2005/01/04
688 Fixed numerious warnings that was issued with newer versions of GCC.
690 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
691 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
694 Make YAZ Generic Frontend Server slightly faster.
696 Enhance (and reduce) logging for Generic Frontend Server.
698 Revert YAZ log system so that it flushes every write operation
699 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
701 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
702 instead of LOG_, due to name clash with syslog(3). LOG_ are still
703 present. New applications should define YAZ_USE_NEW_LOG=1 - this
704 will effectively disable old definitions.
706 --- 2.0.28 2004/11/09
708 Added yaz_log_time_format which specifies log format using
711 Added yaz_log_module_level which returns mask for a module. Value
712 is non-zero mask a if module is enabled; zero if disabled.
714 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
715 in include/yaz/cql.h.
717 Fixed bug #176: Dont throw diagnostics on empty SRU args.
719 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
721 Fixed bug #172: RPM builds does not enable SSL.
723 Doxyfile.in part of dist. Doxyfile generated by configure.
725 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
726 are given and the corresponding component does not exist.
728 Extend CCL documentation in YAZ reference. Describe r=r.
730 --- 2.0.26 2004/10/01
732 Fixed MARC->MARCXML conversion to properly deal with
733 fields, subfields, indicators having non-ASCII characters.
735 Fixed MARC->MARCXML conversion so that ASCII control characters
736 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
739 Added YAZ GFS support for conversion from Z39.50 surrogate
740 diagnostics to SRW surrogate diagnostics.
742 Bug fix: YAZ GFS did not return schema in explainResponse.
744 --- 2.0.25 2004/09/30
746 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
747 now converts recordSchema to elementSetName as well as schema URI.
749 Fixed bug in COMSTACK that prevented HTTP request packages from being
752 --- 2.0.24 2004/09/29
754 Added CCL facility r=r "range" which is similar to r=o "ordered" but
755 does not require white-space before and after the dash in a range, e.g.
756 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
759 Fixed a few AC_TRY_LINK configure tests that did not operate properly
760 due to new GCC removing "redundant" code.
762 Added yaz-client commands scanpos and scanstep that sets preferred
763 position and step-size for scan.
765 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
767 Added CCL utility ccl_qual_buf which parses one or more CCL
768 spec lines in a buffer.
770 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
771 of name and value - ignoring empty lines and comments.
773 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
775 Added odr_get_element_path which returns current element path for an
776 ODR handle. This utility is useful in error handling or user-defined
779 Added ODR_PRINT utility odr_set_stream which is is a more generic
780 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
781 to a write function and pointer to close function. The close function - if
782 non-NULL - will be called during odr_destroy.
784 Fixed bug in CCL parser where truncation char was not removed from
785 right side when truncation=both was in effect.
787 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
790 --- 2.0.23 2004/08/11
792 Fix buffer overrun in CQL parser when dealing with proximity (%).
794 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
795 to UTF-8/UCS conversion is now only based on codetables.xml.
797 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
799 --- 2.0.22 2004/08/06
801 Add support for more "commit changes" in ZOOM (uses Extended Services).
803 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
806 Yet another small fix for configure of SSL.
808 --- 2.0.21 2004/05/14
810 Fix SSL libs for configure when --with-openssl=DIR is given.
812 --- 2.0.20 2004/05/10
814 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
816 SSL comstack now uses yaz.pem certificate file on server side
817 by default. Certificate filename can be configured by calling
818 comstack function cs_set_ssl_certificate_file before cs_bind is used.
820 Fix bug regarding multiple calls to ZOOM_connection_connect.
822 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
824 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
825 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
827 ZOOM now allows inspection of X509 peer certificate for verification.
828 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
830 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
831 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
832 as "modular" but it simplifies things.
834 Added cs_get_peer_certificate to that returns peer X509 PEM.
836 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
837 NULL if SSL is unavailable.
839 Documentation about MARC decoding tools.
841 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
843 --- 2.0.19 2004/03/30
845 Rename CHANGELOG to NEWS to follow GNU style packing.
847 Fix bug with missing initialization of member in init_diagnostics.
848 This bug affects threaded version of GFS server.
850 --- 2.0.18 2004/03/20
852 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
855 Ensure zlib.dll is packed with Windows install.
857 --- 2.0.17 2004/03/17
859 Fix encoding of xsd:string to use text instead of CDATA.
861 Fix endless loop in CQL parser with unbalanced ".
863 Use a more compact way to store MARC-8 conversion tables.
865 --- 2.0.16 2004/03/16 Debian only
867 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
870 Update CQL parser to use new CQL 1.1 modifiers for booleans and
875 --- 2.0.15 2004/03/01
877 Another fix for decoding of XML packed records.
879 --- 2.0.14 2004/02/25
881 Fixes for Chunked encoding. White space not ignored after length spec.
883 Update NS and use default NS for SRW diagnostic elements.
885 --- 2.0.13 2004/02/23
887 Implement ZOOM_resultset_cache_reset which resets record cache.
889 Implement ZOOM_resultset_sort which sorts a result set.
891 Implement chunked HTTP transfer.
893 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
895 --- 2.0.12 2004/02/16
897 Added member 'schema' to bend_explain_rr structure so that backend
898 can specify explain record identifier. Defaults to Zeerex 2.0.
900 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
902 --- 2.0.11 2004/02/16
904 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
907 Added init command for yaz-client which sends "extra" init request.
909 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
910 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
912 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
914 Make ZOOM error code for "invalid query".
916 Fixed compilation for SSL which wasn't properly enabled for all platforms.
918 --- 2.0.10 2004/02/05
920 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
923 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
925 Added option -p <file> to make Generic Frontend Server to write PID file.
927 Added option -D to put Generic Frontend Server in background on its own.
929 Make ZOOM C recognize option "password". If unset, "pass" is used
930 (for backwards compatibility).
932 Fixed a bug in Generic Frontend Server that could make it crash if a
933 client sets characterSetNegotation bit, but didn't pass negotiation stuff
936 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
937 Must be issued before open, in order to be in effect.
939 --- 2.0.9-6 2004/01/12 Debian/Windows
941 Make the SRU server more picky WRT unknown params, etc.
943 Bug fix: ZOOM scan response didn't return displayTerm - when present.
945 New YAZ client command, options, that sets Z39.50 options.
947 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
948 options from a string of tokens (one token for each option bit).
950 Update SRW diagnostic code messages.
952 --- 2.0.9-5 2004/01/07 Debian/Windows
954 Handle user defined stylesheet for SRW/SRU.
956 --- 2.0.9-4 2004/01/06 Debian/Windows
958 Fix bug in decoding of Content-Length.
960 --- 2.0.9-3 2004/01/06 Debian/Windows
962 Fix a bug with decoding of XML packed records.
964 --- 2.0.9-2 2004/01/05 Debian only
966 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
968 Fix bug in SRW/SRU diagnostics decoding.
972 Fixed bug in Generic Frontend Server which could drop records exceeding
973 preferred message size. Reported and fixed by Irina Dijour.
975 Fixed calculation of package size for structured records in Generic
976 Frontend Server. Reported and fixed by Irina Dijour.
978 Fixed namespace for SRW/SRU diagnostics.
980 Fixed SEGV in yaz-client that occured for HTTP connection errors.
984 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
985 this version is incompatible with version 1.0 and older YAZ SRW/SRU
988 CQL changes to reflect recent changes to the specification:
989 * Documentation talks about context sets instead of index sets.
990 * Documentation talks about indexes instead of qualifiers.
991 * The CQL-to-PQF transformer's configuration file now uses
992 "index.set.name = <attributes>" instead of the old form
993 "qualifier.set.name = <attributes>". (Both forms are still
994 understood but the latter is deprecated.)
995 * CQL terms with no explicit index specified are now interpreted as
996 cql.serverChoice instead of srw.serverChoice (which of course
997 behaves exactly the same.)
1001 MARC conversion can now generate ISO2709 output in another
1002 character set. yaz-marcdump uses this facility if you invoke it
1005 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1006 functions from there can be used from C++.
1008 --- 2.0.6 2003/12/04
1010 Frontend server now transfers memory from decoded packages to stream
1013 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1014 references to show up.
1016 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1017 the ZOOM Abstract API. The older names for the same options are still
1018 also supported for the benefit of old applications.
1020 ZOOM-C supports "implementationId" and "implementationVersion" options
1021 to go along with "implementationName". These allow the user code to
1022 specify identification strings to be sent to servers.
1023 Add OID for the new ExtLite attribute set.
1025 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1026 as requested/supplid by Ere Maijala <ere@atp.fi>
1028 For generic frontend server, reverse the order of
1029 "toolkit-supplied / application-supplied" strings sent as implementationId,
1030 Name and Version. Also, remove the spaces around the slash. This brings
1031 the GFS in line with the behaviour of ZOOM-C on the client side.
1033 Add function ZOOM_scanset_display_term.
1035 yaz-client shows scan displayTerm if present.
1037 Utility yaz-iconv is now installed by default along with the man page
1040 Extend configure check for OpenSSL to use pkg-config where available (such
1043 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1044 server to specify uid/gid/mask for socket using the format
1045 unix:[user=uid,][group=gid,][umask=mask,]file=path
1046 If file= is omitted the existing format is assumed, e.g.
1048 in which case the mask is 0666 (rw for everybody).
1050 Major restructure of YAZ source. All source in libyaz is in src directory.
1051 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1052 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1054 Added man page for utility yaz-marcdump (used to be called marcdump).
1055 yaz-marcdump is installed by 'make install'.
1057 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1058 of incoming package failed.
1060 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1062 Change prototype of odr_perror: add const to message string.
1064 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1066 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1067 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1068 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1069 DNS lookup. There should not be any compatibility problems with this
1070 assuming that blocking=1 or 0 is used.
1072 Fix bad reference in UNIX comstack in function cs_addrstr.
1074 Fix for compilation on AIX.
1076 The generic front-end server (server/seshigh.c) now supports returning
1077 Init diagnostics to the client in User-information-field, in
1078 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1081 --- 2.0.4 2003/09/04
1083 Allow any CQL relation (not just all,any,exact,scr).
1085 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1086 that features the same UI.
1088 Implemented command update0 in YAZ client which is equivalent to
1089 update but uses old of Ext Update ASN.1.
1091 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1092 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1093 Previously no OID was used for this info.
1095 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1096 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1097 returns 'malformed search term' otherwise.
1099 SortResponse member resultCount now set to NULL in sort handler of
1102 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1105 Add three new utility functions for translating OIDs between various
1106 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1107 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1108 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1109 char *oid_to_dotstring(const int *oid, char *oidbuf);
1110 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1112 Reverted modifications for ES Update definition for z_IU0Update
1113 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1114 is back to YAZ 2.0.2.
1116 String value attributes for CCL parser.
1118 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1119 which their FirstSearch server returns in Init responses, sometimes
1120 carrying useful diagnostic information when Init fails. This has the
1121 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1122 "z39.50/oclcui.asn", where its definition is somewhat different from
1123 what OCLC document on their web-site, as required to interoperate with
1126 Support for anonymous authentication in yaz-client. Use the command
1129 * Fix the OID of the Index Data-local "admin" Extended Service from
1130 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1131 the 1000, which indicates a locally-defined OID, was a mistake.
1133 --- 2.0.3 2003/06/20
1135 Fix CCL directive @case handling so that it affects string match for
1136 both CCL keywords and qualifiers.
1138 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1139 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1140 Decoder has been updated with ASN.1 changes as listed in
1141 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1142 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1143 z_IUUpdate, remains unchanged.
1145 ZOOM_record_get may now return a record in a specific character set.
1146 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1147 "from" is the character set of record as returned by target. "to" is
1148 the character set to be returned. If omitted, "to" is UTF-8.
1150 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1152 New ODR utility, odr_getelement, which returns name of element for
1153 which encoding/decoding failed.
1155 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1156 in cases where a required element was omitted.
1158 Bug fix: some MARC8 sequences were not converted.
1160 New ZOOM option "step" which specifies number of records to be
1161 retrieved in one chunk. Used in conjunction with "start" and "count".
1163 SRW support for yaz-client. Use scheme http: to use it, e.g.
1166 yaz-client no longer does (un)intelligent character set conversions
1167 by default. Can be enabled with charset and marc_charset commands.
1169 xmalloc trace fix for 64-bit systems such as DEC alpha.
1171 Solaris 2.6 compile fix.
1173 New function, cql_strerror() translates SRW error codes, as returned
1174 by cql_transform_error(), into human-readable English strings. Used
1175 in yaz-client diagnostics when appropriate.
1177 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1178 converts it into a type-1 query which is sent to the server. This
1179 makes CQL available for use with all Z-servers, as opposed to the tiny
1180 minority that can handle CQL queries themselves.
1182 --- 2.0.2 2003/04/28
1184 New Debian package layout similar to the Redhat Package layout.
1186 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1187 and search result respectively.
1189 --- 2.0.1 2003/04/25
1191 Redhat package is now several packages: libyaz (runtime libraries),
1192 libyaz-devel (development and documentation, and yaz (utility programs).
1193 Package spec file by Morten Bøgeskov.
1195 New member 'schema' in struct bend_fetch_rr which the name of requested
1196 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1197 handler MAY set this to reflect the schema of the returned record.
1199 New member 'display_term' in struct scan_entry. GFS now sets member entries
1200 and allocates scan entries to be filled by user scan handler. In previous
1201 version, entries member was allocated by the scan handler. That still works,
1202 but the GFS will ignore member display_term - assuming it was NOT set by
1203 the handler. The fact that the GFS now allocates the entries both allows
1204 for new members and makes a scan handler easier to write.
1206 Fix CQL lex buffer overflow.
1208 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1209 SRU default recordPacking is string.
1211 SRU protocol support for frontend server.
1213 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1215 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1217 Added scan for the ZOOM shell (zoomsh).
1221 * String Identifers for Schemas (Amendment 5).
1222 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1223 Old definition for schema
1224 Odr_oid *schema; /* OPT */
1229 Z_InternationalString *uri;
1230 #define Z_Schema_oid 1
1231 #define Z_Schema_uri 2
1234 * resultCount parameter to Sort Response (Amendment 1).
1235 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1237 Support for SRW 1.0 over HTTP. This is an optional feature and
1238 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1241 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1242 on the same port. SRW SearchRetrieveRequests are mapped
1243 to bend_init,bend_search,bend_fetch,bend_close.
1245 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1247 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1248 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1250 ZOOM connections are SRW based if schem http is used for hostname
1251 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1252 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1254 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1255 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1256 distance=n, order=true/false, relation=le, prox unit=word. If
1257 n is omitted, distance 1 is used.
1259 Fixed problem with C compiler include path in wrong order.
1261 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1262 on Solaris. Patch from Ko van der Sloot.
1264 New MARC decode API. All new functions operate on a yaz_marc_t
1265 handle. The most important new functions are: yaz_marc_create,
1266 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1267 decode and destroy respectively. Decoder can produce formats
1268 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1269 include/yaz/marcdisp.h.
1271 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1272 to UTF-8, UCS-32, wchar_t or Latin-1.
1274 * Prototypes for yaz_iconv_-functions moved to separate header
1275 include/yaz/yaz-iconv.h.
1277 Make a few private functions 'static' in unix.c. This prevents
1278 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1280 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1281 are set when Init Response is received.
1283 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1284 but returns diagnostic set as well.
1286 New function yaz_strerror which is a portable wrapper for
1287 strerror/strerror_r/GetLastMessage.
1289 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1290 is returned for MARC. If type is "oai", then OAI MARC is returned.
1292 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1295 --- 1.9.2 2002/11/26
1297 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1299 Fix bad race conditions on SIGTERM and terminate gracefully in
1302 Move retrieval (data1) module to Zebra since nobody seems to be
1305 Add GRS-1 render for ZOOM using same format as yaz-client.
1307 --- 1.9.1 2002/10/05
1309 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1311 Fix broken ESpec handling in data1 module.
1313 SGML reader parses comments and makes them part of the data1 tree.
1315 Added several type casts so that YAZ compiles as C++ code.
1317 ZOOM didn't handle PDU encoding failures properly.
1319 Added more Bib-1 diagnostics (approved extensions).
1321 GNU configure: better check for iconv.
1323 More portable use of accept, getpeername. Check for socklen_t. Use
1324 int/size_t if socklen_t is not defined.
1328 PQF parser rejects bad queries - including those with extra
1329 characters in them. PQF parser used to silently ignore that.
1330 Cleaner API for PQF added, which allows you to get detailed
1331 error information for bad queries (see yaz/pquery.h).
1333 Fixed bug in ZOOM_record_get for type "database".
1335 Implemented mini iconv library supporting conversions between
1336 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1338 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1340 --- 1.8.9 2002/08/20
1342 Fixed ZOOM C record cache so that preferredRecordSyntax and
1343 elementSetName is used to check for already fetched records.
1345 --- 1.8.8 2002/08/02
1347 Added three members in bend_initrequest structure to facilitate
1348 character set negotiation.
1350 Fixed a bug in frontend server that could cause indefinite
1351 loops under rare conditions.
1353 Revised character set utilities (charneg.h) so that encoding
1354 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1356 For PQF, directive @term <type> sets term type for Scan/Search.
1357 Here <type> is general, string, numeric, null. The term type
1358 is inherited - just like @attr.
1360 New call odr_set_charset that sets character set conversion for
1361 international-strings on a ODR stream. Prototype is:
1362 int odr_set_charset(ODR o, const char *to, const char *from);
1363 The InternationalString is still represented as C string in YAZ
1364 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1365 won't). On the protocol level, you can use any encoding.
1367 Support for UNIX sockets in ZOOM.
1369 Solaris recv sometimes returns errno == ENOENT. It is treated as
1370 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1372 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1373 both client and server. Code by Morten Bøgeskov.
1375 --- 1.8.7 2002/05/22
1377 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1378 that they can be used directly from Visual Basic. You must recompile
1379 your windows APP if you're using ZOOM.
1381 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1382 Commands "lang" and "charset" sets language and character set respectively.
1383 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1384 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1386 Attributes from multiple CCL fields may be OR'ed rather than merged
1387 using directive "@field or". Fields are still merged by default -
1388 equivalent to "@field merge".
1390 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1393 Fixed bug in zget for parameter ExtendedServicesResponse.
1397 --- 1.8.6 2002/03/25
1399 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1401 Client displays USR.1:SearchResult-1 (hits per term).
1403 Additional Search Info for search in Generic Frontend Server.
1405 Fixed CCL parsing of "field=s".
1407 WIN32 installer - using the excellent NSIS software from nullsoft.
1409 Fixed CCL parsing of "field = - <number>".
1411 Added function yaz_marc_decode that decodes MARC for line mode
1412 display or XML (similar to that used by JZKit).
1414 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1415 Z39.50. But ISO/ILL was, however.
1417 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1418 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1421 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1423 --- 1.8.5 2002/02/03
1425 New YAZ client features: Command completion and new commands:
1426 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1427 Code provided by Jacob Poulsen.
1429 New call oid_trav, that visits all registered OIDs via callback.
1431 Function ZOOM_record_get now returns const char pointer rather than
1432 void pointer. It saves a lot of type casts.
1434 For YAZ client, command "auth" now allows you to set authentication
1435 in IdPass style. It is enabled when three tokens are given - order
1436 is user, group and password.
1438 Fix memory leaks in MARC record handling for ZOOM.
1440 New option for YAZ client, -k <kilobytes> that sets
1441 maximum record size. Similar to -k option for generic frontend
1442 server and yaz-ztest.
1444 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1446 Prefix query parser reports "fail" when bad attribute set is given.
1448 Fix in MARC decoder. Proximity logging. Fix for attribute set
1449 in scan handler for server. Patches by Shigeru Ishida.
1451 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1454 Configure option --with-openssl=<dir> now works when a directory is
1455 specified. Patch provided by Morten Bøgeskov.
1457 New option for YAZ client, -u <auth>, that sets authentication.
1459 ZOOM fix: error information was sometimes "missing", since error
1460 was cleared/reset too when it shouldn't.
1462 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1464 --- 1.8.4 2002/01/04
1466 Scan for ZOOM API. New object ZOOM_scanset. New functions
1467 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1468 ZOOM_scanset_destroy.
1470 New ZOOM function, ZOOM_connection_last_event, that returns type
1471 of last event (such as "receive data", "send data", "apdu received",
1474 New ZOOM option, schema, that specifies schema for retrieval.
1476 New CCL feature. Qualifiers can be aliases for one or more
1477 other qualifiers (if more than one is given, OR is used).
1479 ZOOM uses named result sets if target supports it.
1481 Two new YAZ client commands: . (dot, which sources a script of YAZ
1482 client commands), and ! (to execute shell command.). Implemented
1485 Working on Debian packages.
1487 --- 1.8.3 2001/11/19
1489 YAZ client enables named result sets only if target supports it.
1491 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1493 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1494 with key="host" to get same result.
1496 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1497 Function Z3950_resultset_record(s) returns references to records
1498 "owned" by resultset. To become owner use Z3950_record_clone.
1500 Function z_ext_record handles Extended Services. Thanks to
1503 --- 1.8.2 2001/11/12
1505 CCL Parser fix: ignore token comma when dealing with and-lists.
1507 Documentation updates for COMSTACK.
1509 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1510 Changed prototype Z3950_records. For some functions, int parameters
1511 were changed to size_t.
1513 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1516 New MARC decode/display function, marc_display_exl, which properly rejects
1517 non-ISO2709 records. YAZ client uses it.
1519 --- 1.8.1 2001/10/29
1521 Fix bug: local attribute set wasn't set correctly in PQF strings.
1525 * Old Z39.50 codecs no longer supported.
1527 Added ZOOM C binding. See http://zoom.z3950.org/
1529 Renamed states for COMSTACKs to avoid confusion with events.
1531 Implemented cs_look and proper cs_rcvconnect.
1533 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1535 Configure detects POSIX threads on OpenBSD.
1537 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1538 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1540 When error is returned from present handler, non-surrogate diagnostic
1541 is returned in present response (and fetch handler is no longer called).
1543 * Minor adjustments to pquery parser (PQF). Token characters may be
1544 escaped by using backslash (C-style).
1546 PQF parser allows string attribute values to be specified. For @attr,
1547 non-numeric characters after the equal-sign are treated as strings
1548 (e.g. @attr 9=title).
1550 CCL trunction character may be defined (@truncation in file)
1552 * function zget_ExtendedServicesRequest sets waitAction to
1553 waitIfPossible (was wait).
1555 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1558 CCL operator names may be set in field definition files (CCL_bibset).
1559 See ccl/bib1 for an example.
1561 Fixes in ASN.1 compiler for C++ compatibility.
1563 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1564 and "op_or" to avoid conflict with C++.
1566 Fixed problem with GNU readline detection on Redhat 7.0.
1568 Added step-size for Scan backend handler.
1570 Fixed bug that made the frontend server crash when no attribute
1571 set was specified for scan.
1573 Front-end server automatically switches to original working directory
1574 when installed as an NT service. Previously -w had to be specified to
1577 Added extended attributes for retrieval module (data1), so that data1
1578 records carry d1_readXML/SGML attributes. d1_read also supports
1579 null-data rules ( <tag/>)
1581 On UNIX when POSIX threads are available, a separate library libyazthread
1582 is created. Programmers should link with that library and the yaz library
1583 when using threads. The reason for the split was that some applications
1584 on Linux, such as Apache, doesn't work well when using shared objects that
1587 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1588 (or any frontend server) in SSL mode by specifying ssl: followed by
1589 address. Only tested on UNIX.
1591 Added feature for CCL module. Virtual structure s=al or s=ol generates
1592 and-list and or-list respectively instead of phrase search.
1596 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1597 log_mask_str. This was done to avoid name conflicts with other libraries
1598 (such as other PHP extensions).
1600 Added raw OID member for preferred record syntax (request_format_raw)
1601 and returned record syntax (output_format_raw) for backend fetch method.
1603 Config file yaz-config now accepts options so that it returns specific
1604 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1606 Shared library support for UNIX using GNU libtool.
1608 * Modified backend interface. Request/Response struct's replaced by
1609 one read/write C struct. For example bend_fetchrequest and
1610 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1611 Every handler - even search has to be registered in bend_init
1612 handler. This means that the YAZ library no longer refers to
1613 external functions and it makes it possible to make the whole
1614 thing a single DLL/SO.
1616 Added Segment handler for backend server.
1618 Added Zmbol/Zebra administrative functions to YAZ client.
1620 Threaded frontend server on UNIX (when POSIX Threads are available).
1621 Starting the server with option -T enables multi-threading.
1625 Added configure option --enable-comp/disable-comp to control use
1626 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1627 located in sub directory asn.
1629 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1630 in ${exec_prefix}/bin along with the other programs yaz-client and
1633 GNU automake used to maintain makefiles.
1635 Added several OID's.
1637 Changed retrieval module so that we can load records with no abstract
1638 syntax defined. Tagpaths in these records are fully composed of string
1641 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1645 On UNIX, the generated makefile now supports a proper 'make install'.
1646 The prefix can be set via GNU configure to set the install location
1647 (default is /usr/local).
1649 * YAZ programs client and ztest were renamed to yaz-client and
1650 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1651 locations, such as /usr/bin,/usr/local/bin,etc.
1653 * YAZ Header files were moved from include to include/yaz. YAZ Header
1654 files are referred to as include <yaz/log.h> rather than <log.h>.
1655 The YAZ include path (-I ..) is therefore the same as before. Programmers
1656 should update their #include statements or use -Ipath/include/yaz
1657 instead. The main motivation for doing this change is that YAZ header files
1658 can be installed in "standard" locations /usr/include,/usr/local/include
1659 without introducing conflicts, since ALL YAZ header files are stored
1660 in subdirectory yaz (under /usr/include for example).
1662 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1663 rather than project/workspace files. We switched because project files
1664 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1667 Changed name of logging function, logf, to yaz_log, to prevent name
1668 clash with some math-log functions. The YAZ header log.h defines logf
1669 to yaz_log (#define) so there should be no incompatibilities by this
1672 Added bend_start/bend_stop handlers for server. These handler are
1673 called on start/stop of server. For windows they are called whenever
1674 a service is started/stopped.
1676 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1677 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1678 in util/yc.tcl. The auto-generated C code structures are, in a few
1679 cases, incompatible with the old decoders. There are differences in the
1680 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1681 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1682 The preprocessor variable ASN_COMPILED is defined when the compiled
1683 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1684 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1685 wish to use the old encoders/decoders you can specify --disable-yc
1688 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1689 version so that it supports both new - and old version of DB Update
1691 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1692 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1693 change. The name parameter can be set to 0 in which no name is specified
1694 for the construction. The macros odr_implicit and odr_explicit sets name
1695 parameter to zero for the construction involved. New macros
1696 odr_implicit_tag and odr_explicit_tag are similar to the others,
1697 except that a name parameter is added. For programmers' that don't use
1698 ODR they probably only need to change the call to z_APDU and z_External.
1700 Added access control facility by interfacing the TCP wrapper library.
1701 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1702 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1703 name of the daemon and enables the access control as specified in
1704 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1706 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1707 den Dool <H.M.vdnDool@kub.nl>.
1709 Added reference ID parameter to most functions in server API - refer
1710 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1712 Changed name of ccl library to libccl.a (was ccl.a).
1714 Fixed bug in decoder for Explain (Category TargetInfo).
1716 Added support for GNU readline in client. Thanks to Jacob Poulsen
1717 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1719 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1720 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1721 IMPLEMENTATION! This change was made to the development version before
1722 the ZIG decided to retract the amendment. If any users MUST be
1723 compatible with the original Update definition, PLEASE CONTACT US, and
1724 we will include a separate definition corresponding to the old Update
1725 ES. Note that because of the change to the ASN.1 of the
1726 TaskPackageRecordStructure we cannot define a single structure that
1727 will support both versions.
1729 * Added const modifier to buffer parameter for some ODR/BER encoding
1730 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1731 completeWAIS, odr_dumpBER.
1733 Fixed bug in client.c which caused a crash when a scanResponse didn't
1734 contain positionOfTerm.
1736 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1737 * will cause an error in a client if a non-YAZ target sends both a
1738 * list of Scan entries and non-surrogate diagnostics.
1740 Retrieval module enhancements. Tag sets may be typed in the reference
1741 to it. From the .abs-file the "tagset" directive takes a third optional
1742 integer type for the tag set referenced. From a .tag-file the "include"
1743 directive takes a third optional type as well. The old "type" directive
1744 in the tag set itself is still recognized but acts as the default type
1747 Backend interface change. Individual Scan terms returned from bend_scan
1748 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1749 in include/backend.h.
1751 Retrieval module enhancements. Multiple tag sets and attribute sets may
1752 be specified in abstract syntax specs. Revised the error/warning for
1753 logging messages reported by the retrieval module when reading the
1756 Object Identifier system (oid_..) changed. The API is backwards
1757 compatible but the oid-routines now allocates new OID's when needed.
1758 Raw OID's may be specified in oid_getvalbyname.
1760 YAZ now uses GNU configure to generate Makefile(s).
1762 * Minor changes in some of the member names of DeleteResultSetRequest and
1763 DeleteResultSetResponse. See include/proto.h.
1765 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1766 and added member 'languages' in TargetInfo (which was missing).
1768 Changed the way attribute sets are handled in the retrieval
1769 module. These are now cached, just like the abstract syntaxes
1772 Changed YAZ so that it links with compiled ASN.1.
1774 Added Explain-schema definitions and mapping routines. The following
1775 Explain categories have been implemented: AttributeDetails,
1776 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1778 Fixed minor bug in Windows version of Server Library.
1780 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1782 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1784 Added EXTERNAL: UNIverse Resource Report (non-standard).
1786 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1787 ENUMERATED and SET OF.
1789 * Added 'const' to some of the char pointer arguments for the
1790 functions, data1_read_node, data1_getelementbytagname,
1791 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1794 Fixed bug in data1_insert_taggeddata - the last_child member of
1795 parent wasn't initialised.
1797 * Changed data1_read_record and data1_read_node so that the supplied
1798 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1799 doesn't refer to any parts of the "SGML"-buffer.
1801 Fixed bug in server library (Windows version of statserv_remove).
1803 * Changed code so that it compiles as C++. The type definition
1804 of Odr_fun which is a member of Odr_arm was changed. The result is,
1805 that an explicit typecast is needed for the fun pointer when
1806 using Odr_arm - as in:
1807 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1809 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1811 Implemented the new structured date and time definition as approved
1812 by the ZIG. Added schemaId element to the specificTag in Espec-1
1813 (also approved at the last ZIG). Thanks to RVDM.
1815 Added some Object identifiers (RVDM).
1817 Changed the Update Extended Service (RVDM).
1819 Added command "refid" to client which specifies referenceId for
1820 the following requests.
1822 Implemented extended service handling for server. See ztest.c
1823 for an example as well as backend.h. New handlers are registerd
1824 in the Init handler.
1826 * Changed interface for sort in server.
1828 Added new members to statserv_options_block. It allows a server
1829 to read options from another source than just the command line. Thanks
1830 to Charles Woodfield.
1832 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1833 renamed to zboolean. Some C++ compilers complained about the name.
1835 Minor changes to gils.abs. Added index 's' (sort) on title
1836 and date/time-last-modified.
1838 --- 1.4pl2 1998/1/30
1840 Fixed bug in server library regarding inetd mode (-i). This bug
1841 was introduced by release 1.4.
1843 --- 1.4pl1 1998/1/29
1845 Added sort facility in client and backend server interface.
1847 Fixed problem with dependencies in Makefile(s).
1849 Fixed bugs for encoders/decoders of extended services and
1852 Implemented sub-tree feature for schemas. Sub-trees are
1853 referenced in *.abs-files. See explain.abs for an example
1854 of the use of this feature.
1856 Modified bib1.att; local attributes for ANY didn't include
1857 ANY itself (only affects use of the retrieval module).
1859 Fixed bug in plain SGML reader in function data1_read_node:
1860 tags with prefix "var" was incorrectly interpreted as variants.
1862 Added feature "sub-schemas" to enable references to - and definitions
1863 of - group of elements.
1865 * Removed member parent from type data1_element (in data1.h).
1867 Implemented function odr_nullval() that returns the value of
1870 * Removed member num_children from data1_node (in data1.h).
1872 Made NT service interface part of the server library. The
1873 function statserv_main uses the NT service when required and
1874 calls the statserv_start / statserv_close routines.
1876 Routine zget_SearchRequest and zget_PresentRequest fills
1877 resultSetName/Id member with "default" instead of "Default".
1879 Fixed memory leak in server. Request queue member wasn't freed.
1881 Fixed nmem_exit so that memory is freed.
1885 Revised the CCL parser utility to be thread safe.
1887 Added function, oid_ent_to_oid, to replace the function
1888 oid_getoidbyent, which is not thread safe.
1890 * Added nmem_init and nmem_exit to initialize and release
1891 NMEM resources. Function nmem_init should be called once in the
1892 initial thread before NMEM/ODR is used. statserv.c and client.c
1893 have been changed accordingly. The change was necessary to make
1894 NMEM thread safe. The NMEM memory pool is shared amongst threads
1895 in a process. Unix-based applications will still work fine without
1898 Added NT Services interface for the the Z39.50 (statserv) Server.
1899 Refer to the ztest.c source on the usage.
1901 Windows 95/NT port using MSVC5.0. Project files are included in the
1904 * Defined new 'global' handle for the retrieval (data1) system. The
1905 new handled, data1_handle, describes the state of the data1 system.
1906 This handle is passed as first argument to virtually all
1907 data1 related routines. The functions data1_create and data1_destroy
1908 creates and destroys a data1 handle respectively.
1910 Added ODR encode stream member to all backend request structures
1911 init, search, scan etc. This stream should be used to allocate all
1912 memory used for the response when thread safe operation is needed.
1914 Changed the comstack utility, cs_addstr, to be thread safe. The
1915 returned hostname string returned by the function is now part the
1918 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1919 function. The cs_straddr takes a COMSTACK handle as argument, so this
1920 function must be used after cs_create and before bind/connect.
1921 This function is thread safe.
1923 Moved test server to 'ztest' directory - generic server code still
1924 in 'server' directory.
1926 Made prefix query (pquery.c) utility thread safe.
1928 Added new function modifier YAZ_EXPORT to 'export' public DLL
1929 functions when using windows (see include/yconfig.h).
1931 Added definitions to the OID database (util/oid.c) (RVDM).
1933 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1935 Added call to ccl_rpn_delete in client program.
1937 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1938 release of RPN structure.
1940 Added support for C++, headers uses extern "C" for public definitions.
1941 With input from RVDM.
1943 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1944 Thanks to Ronald van der Meer (RVDM).
1946 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1948 Added support for private extensions to the OID database
1949 (oid_setprivateoids()). Thanks to RVDM.
1951 Added optional, physical ANY (key replication)
1953 Fixed null-reference problem in GRS-1 output filter.
1955 Proximity operator added to Prefix Query Format (PQF).
1957 In test client command "base" accepts multiple databases.
1959 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1963 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1965 Smallish bug-fixes in the new encoders/decoders (explain).
1967 Bug fixed in DeleteRequest.
1969 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1971 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1973 Added SOIF syntax (using private OID for now) to retrieval module and client.
1975 Added Update extended service.
1977 Added SearchResult-1 additional info structure.
1979 Added optional CCL (ISO8777) interpreter as separate module. Available
1982 --- 1.2 1996/6/10 (1st anniversary release)
1984 Added Summary record syntax. Lightly tested.
1986 Added OPAC record syntax. Untested.
1988 Added ResourceReport service encoders/decoders. Untested.
1990 Fixed bug in z_Unit - wrong tagging on unitSystem.
1992 Fixed bug in the DiagRecs decoder.
1994 Added options for max PDU size and session timeout to frontend-server.
1996 Added documentation of query-language parsers and other supporting utilities.
1998 [frontend-server] Added Attribute set to the bend_scanrequest API.
2000 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2001 surrogate diagnostics were generated.
2003 [retrieval] Allow multiple local values for attribute.
2005 [retrieval] Allow multiple attributes per element in .abs files. index type.
2007 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2009 --- 1.1pl2 1996/4/10
2011 Minor changes, mostly specific to Zebra's requirements (retrieval)
2015 Repaired bug in frontend server when running multiple listening
2016 endpoints in dynamic mode.
2018 z_External() now won't break if a known, ASN.1 value comes encapsulated
2019 in an octet-string. The value will pass through unmodified in an Odr_oct.
2021 Added a bit of code to the demo client to decode & display
2022 ASN.1-structured records represented in the octet-aligned branch of
2023 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2025 Added z_ext_getentbyref() to the ASN module. Doc updated.
2027 * Completed the SCAN definition in the ASN module. This may break SCAN
2028 code based on older YAZ-versions at compile-time. The fix is easy -
2031 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2032 under the SCAN definition. Remember to initialize this, server-people.
2034 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2035 that this does not extend to ODR and ASN.
2037 Comstack allows insertion of established socket (primarily for
2038 inetd-operation of servers). Doc updated.
2040 Front-end server can now start from the inetd in TCP mode. Doc
2043 --- 1.0pl4 1996/1/24
2047 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2048 the rank and record number.
2050 Adjustments to the frontend server.
2052 Fixed diagnostic BER dumper. It ignored the file argument.
2056 Various changes to retrieval module.
2058 Changed the union discriminators of the protocol files from enums to
2059 ints paired with #defines.
2061 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2064 *Changed operator in the RPN structure to 'roperator', again to avoid a
2067 Fixed problems in Explain decoders/encoders.
2069 --- 1.0pl2 1995/12/6
2071 Memory bug in log module fixed.
2073 --- 1.0pl1 1995/12/5
2075 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2077 Bug in Explain DatabaseInfo module fixed.
2079 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2083 The shift to v1.0 signals that we now consider the *core* functionality
2084 of YAZ reasonably stable (the core being more or less equivalent to
2085 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2086 tested (Explain not at all - though that will happen soonish).
2088 Minor changes to code to support Windows port.
2090 Various minor changes after we're getting to use GRS-1 & co. more.
2092 Added Espec-1 format.
2094 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2095 of the protocol and it cannot be selected when encoding (maps into 'string'
2096 when decoding). Needed to talk to some servers.
2098 Demo client can request simple element set names.
2100 Added Diagnostic Format encoders/decoders.
2102 Added simple Close handling to frontend server (no hooks for resource
2103 reporting yet), and demonstration client.
2105 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2107 --- 1.0b3 1995/08/24
2109 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2110 handled incorrectly when records were requested in the searchResponse. This
2111 will only affect you if you use the frontend-server.
2113 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2114 Test-client will ask for and print GRS1. Ztest will return dummy records
2117 Added Explain encoders/decoders to the service-level API. Untested.
2119 Added Extended Services: Item Order encoders and decoders to the Service-
2120 level API. Untested. We could use a recent copy of the pertinent bits
2121 of the ILL protocol to add those bits.
2123 Added diagnostic format 1 encoders/decoders to the service-level API.
2126 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2127 odr_cons.c, which causes a more correct output.
2129 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2130 was always set to 0 when no records were requested in the searchRequest.
2132 * Added better external-handling. This shouldn't harm old code that
2133 *encodes* externals. It can break code that looks for a
2134 'single-ASN1-type' representation, since those types that are known
2135 are now decoded immediately. Look at the SUTRS sample code in
2136 seshigh.c and client.c. Documentation updated.
2138 Handling of structured records in bend_fetchresponse. Length -1 marks
2139 structured record, type is deduced from format field.
2141 --- 1.0b2 1995/06/27
2142 Fairly quick maintenance release to add SUTRS support.
2144 Fixed handling of SUTRS records in the demonstration client.
2146 * Added format field to the bend_fetchrequest and bend_fetchresponce
2147 structures of the backend API (frontend server). When the record is
2148 returned, the value of the format field is mapped to an OID. The
2149 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2150 of the record. The special value VAL_NONE in the bend_request means
2151 that no specific format was requested by the client. Documentation
2152 updated accordingly. Test server (ztest) will return a fixed dummy
2153 SUTRS record if your client requests SUTRS.
2155 Documentation updated accordingly.
2157 You can now set external libraries and RANLIB support in the top-level
2161 First public release.
