3 Fixed bug in character set conversion of BER strings. Bug introduced
8 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
10 For OID class, use oid_class consistently.
12 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
15 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
16 character set for bibliographic information interchange". By Giannis Kosmas.
18 Added documentation on new OID API.
22 Changes to generic frontend server interface: added new member
23 'query_charset' for bend_initrequest structure. A backend init handler
24 should set this member to its native character set for query terms.
25 When defined, the frontend server logic will announce this character set
26 to a client if the negotiationModel bit is set by the client. All server
27 implementors are encouraged to specify this. If a backend server does not
28 specify this a warning is issued using yaz_log(YLOG_WARN,..).
30 Added CCL utility to remove terms (stop words) from resulting RPN
31 tree. This is handled by functions with prefix ccl_stop_words_ .
33 New ZOOM C option, "rpnCharset", which allows client-side conversion of
36 Clean-up the CCL API. Moved some internal structures from ccl.h to
37 private header cclp.h. Changed ccl_parser_create so that a Bibset must
38 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
39 This is replaced by ccl_parser_find_str which takes a string instead.
41 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
42 libyaz.la is the core of YAZ except the generic frontend server and
43 does not depend on POSIX threads anymore. libyaz_server.la is the
44 generic frontend server facilities and uses POSIX thread functionality
45 if available. The libyaz.la no longer depends on POSIX threads because
46 the number of global structures is limited. NMEM no longer re-uses blocks
47 between threads ; it simply free's memory immediately but allocates in
48 "large" chunks as usual. We don't expect any performance penalties
49 because of this. The yaz_log system is still using a global log_level so
50 caution must be taken when modifying it with yaz_log_init_.. +
51 yaz_log_mask_str. This, however, should not cause any trouble because
52 these functions are called during initialization of application code
53 anyway. `yaz-config --libs server` returns libs for server applications;
54 `yaz-config --libs` returns libs for non-server applications.
56 New OID database - with public definitions in oid_db.h. Removed old OID
57 database including the head oid.h and definitions such as enum oid_value
58 and struct oident. The new OID database uses the same string names as
59 before but the 'protocol' is gone. There are now only two representations
60 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
61 converts from string to OID; functions with prefix yaz_oid_to_string
62 converts the other way.
64 Change to emit_term() in CQL-to-PQF query translation: when a term has
65 the /regexp relation modifier, do not process it for leading and
66 trailing "^" and "*", which have quite different meanings in regular
69 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
70 write handlers no longer carries a 'last' parameter. This will make
71 yaz_iconv flush "less" characters. A flush is performed by call to
72 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
74 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
75 removed, because function yaz_query_to_wrbuf does the same.
77 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
78 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
80 Deprecated MARC utility functions removed.
82 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
85 Branch split: YAZ_2_1_55_branch
89 Fix to ZOOM-C so that transparent reconnection is properly handled on
90 connections that are in asynchronous mode.
92 Fixed compilation on OpenBSD 4.0.
94 Large strings in GRS-1 records are now properly displayed in yaz-client.
96 Added character conversion support for "advancegreek"; based on patch from
99 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
100 sequence is met. Before the error was not set so it would be unknown.
102 Adjust yaz-marcdump MARC reader so that it skips until record separator
105 --- 2.1.52 2007/03/07
107 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
108 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
109 fd_set structure used as a bitmask for the FDs to be selected on.
111 Using ACX_PTHREAD macro to check for POSIX threads.
113 Fixed have-vsnprintf check.
115 --- 2.1.50 2007/02/23
117 Fixes for configure on BSD. Bug #900.
119 Added snprintf/vsnprintf wrappers for systems that don't have
120 limits (heavens forbid).
122 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
123 created before all previous tasks were completed and removed from the
124 task queue, the new task could be removed by a mistake.
126 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
128 Implemented pass-through CQL-to-PQF conversions. Bug #861.
130 Fixed bug #832: Problem with MARC/charset in yaz-client.
132 Fixed bug #668: save command line history for yaz-client.
134 Fixed bug #830: pkg-config support.
136 --- 2.1.48 2007/01/23
138 Extended ZOOM result set options with two options that may be read by
139 a client: resultSetStatus and presentStatus with values as specified for
141 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
143 Fixed bug #827: Using SSL fails on Debian etch.
145 Fixed bug #826: Weird looking chars for set of MARC records.
147 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
148 that is treated as an ItemOrder with itemRequest being an XML document
149 external. The value of "doc" is the content.
151 Extended the GFS search facility. New member of bend_search_rr
152 'estimated_hit_count' signals that hits is known to be an estmate
153 (higher or lower than real hit count). New member 'partial_resultset'
154 signals that the search was partial (hit count is lower or equal than
155 real hit count). For Z39.50, the information is stored in resultSetStatus
156 member of SearchResponse APDU. For SRU, the information is signalled
157 via SRU diagnostic 59: "Result set created with valid partial results
160 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
162 --- 2.1.46 2007/01/13
164 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
166 Added ZOOM_connection_peek_event.
168 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
169 the following new functions:
170 ZOOM_event_nonblock, ZOOM_connection_process,
171 ZOOM_connection_get_{socket,mask,timeout},
172 ZOOM_connection_fire_event_{timeout,socket}.
173 The existing blocking event handler, ZOOM_event, is a wrapper for the
174 + blocking ZOOM_event_sys_{poll,select}.
176 Implemented function ccl_xml_config which parses XML version of CCL
177 configuration (bug #798).
179 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
181 Added timings utility (yaz/timing.h)
183 --- 2.1.44 2007/01/03
185 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
188 Fixed bug #779: Rotation of apdu.log fails.
190 Fixed for character set conversions:
191 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
192 Honor G1 set in MARC-8 decoding.
194 --- 2.1.42 2006/12/17
196 Fixed bug #775: char conversion does not handle Alternative UTF-8
199 Implemented function yaz_marc_read_line which parses MARC line format
200 records. There is a wealth of formats out there. So far, this function
201 reads line records produced by yaz_marc_write_line.
203 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
204 more generic and easier to remember(!) options: -i format and -o format
205 which specifies input format and output format respectively - where
206 format is one of "marc", "marcxml", "line", "marcxchange".
208 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
209 does not print anything except warnings for records.
211 For yaz-marcdump, added support for MARC split into files (-s) with a given
214 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
215 spec, at http://www.loc.gov/standards/sru/record-update/
216 This has changed the binary layout of the following structs:
217 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
218 bend_update_rr . Patch by Ko van der Sloot.
220 Added GFS utility function bend_assoc_is_alive which returns 1 if
221 association is still alive (client is connected); 0 otherwise (client
222 closed connection). This allows busy servers to stop working for
225 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
226 been a separate piece of software. This version of ziffy has been modified
227 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
229 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
231 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
232 Client code may now interrogate options such as "init_opt_sort" to
233 find out whether the server claims to support various options.
235 --- 2.1.40 2006/11/27
237 Added utilities yaz_{set,get}_esn to set/get element set name from
240 Removed the build of libyazthread.la. The libyaz.so is the threaded version
241 of YAZ and has been so since YAZ 2.1.10.
243 Implemented ZOOM_record_error which returns error information for
244 record (surrogate diagnostic).
246 --- 2.1.38 2006/10/31
248 Updates for SRU Update by Ko van der Sloot:
249 1. Changed name from "operation" to "action"
250 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
251 versions in the code, marked as 'backward compatible'.
252 3. Added diagnostics for SRU Update.
254 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
256 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
258 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
260 For GFS, fixed problem with SRU diagnostic 'First record position out of
261 range' being issued for 0 hits.
263 zoomtst10 part of Windows Build.
265 --- 2.1.36 2006/10/13
267 Implemented yaz_filepath_comp which splits a path into file path
268 components (required by Zebra 2.0.3+).
270 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
271 BSD inspired license until now so this should not have any real impact on
272 anybody. See http://www.opensource.org/licenses/bsd-license.php
274 Fixed bug #687: Missing log lines.
276 Fixed bug #678: CQL to PQF translation does not preserve double-quote
279 Fixed bug #689: SRU diagnostics to be added.
281 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
282 whether a connection is idle (no more work do do).
284 --- 2.1.34 2006/10/04
286 Change type of optval from long to int for invocation of setsockopt with
287 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
289 Added support for specifying the max log file size for the Generic
290 Frontend Server. The size is given with option -r.
292 --- 2.1.32 2006/09/21
294 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
296 --- 2.1.30 2006/09/17
298 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
301 Fixed bug in Generic Frontend Server that could cause a server to stop
302 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
304 For the generic frontend server, the maximum record size is used as maximum
305 size of incoming packages (SRU + Z39.50). The value until was previously
306 only used in Z39.50 Init negotiation and, later, in a session controlled
307 sizes of records returned. This is controlled using -k option. It can be
308 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
310 --- 2.1.28 2006/09/04
312 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
315 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
317 New option for yaz-marcdump -lpos=value which allows setting a portion
318 of MARC header to a certain value.
320 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
322 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
323 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
325 --- 2.1.26 2006/08/15
327 Fixed problem with SRU mode type (soap, get, post) for yaz-client
330 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
332 --- 2.1.24 2006/08/08
334 Fixed MARC ISO2709 encoding routines to deal with character set
337 Minor changes to GFS logging. Database included in search request log
340 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
341 cached/multiple records.
343 Shared libraries are built by default on Unix+configure.
345 Changed cql2pqf transformation to use a different evaluation order. The
346 new order is: always, relation, structure, position, truncation, index
347 and relationModifier. Old order was: always, relation, relationModifier,
348 structure, index, position, truncation. Note that the the latter ones
349 override former ones for identical attributes.. The new scheme means that
350 it is possible to override any existing attribute with a relationModifier.
351 And also that it is possible to override everything for the index rule
352 (except the ones listed in relationModifier). No order is perfect but this
353 one, we believe, covers more real cases.. The "always" should have been
354 called "default", since the attributes there can be overridden with all
357 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
358 compilation phase, but also for yaz-config --cflags output. This allows
359 us to have public headers with Libxml2 stuff in them . It should also,
360 eventually, make Libxml2 checks redundant in packages using YAZ, such
363 --- 2.1.22 2006/06/15
365 Changed SRU update structure bend_update_rr so that SRU diagnostics are
366 stored in uri, message and details.. Previously diagnostics were stored
367 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
368 compatibility.. but he's probably the only one affected, so.
370 Added support for CCL, compiled on the client side, in ZOOM-C. This
371 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
372 input; the resulting query objects can be used for for searching with
373 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
375 YAZ' configure searches for OpenSSL by default.
377 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
378 SL_CTX_use_certificate_file. See
379 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
380 for more info. Thanks to Ko van der Sloot.
382 --- 2.1.20 2006/06/02
384 Bug #600: SRU GET, POST support for yaz-client. Introduced
385 command 'sru' which selects method SOAP/GET/POST.
387 Allow missingValueAction to be specified for the sortspec string -
388 function yaz_sort_spec. By default, the missing value action is null.
389 Use ! to specify "abort". Use = followed by stringvalue to specify default
392 Ensured that Present-handler (if defined) is called in GFS before any call to
393 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
394 searchRetrieve requests.
396 Documentation for YAZ is now based on the Docbook XML/XSLT using
397 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
398 is no longer depending on jade/openjade or docbook-to-man scripts.
399 PDF is no longer part of the distribution - but can optionally be
400 made using DSSSL/jadetex or FOP.
402 Added retrieval handling support in Generic Frontend Server to support
403 conversion between MARC/XML as well as XSLTtransforms. See
404 etc/yazgfs.xml for an example.
406 Added Authentication support to Generic Frontend Server in SRU
407 mode. Authentication using HTTP Basic is supported, as is the use
408 of 'x-username' and 'x-password' parameters in the request itself.
410 Added support for a new character set MARC8s identical to MARC8 except
411 that it converts combined characters to single Unicode characters in the
412 Latin-1 range (when possible).
414 --- 2.1.18 2006/04/24
416 ASN.1 compiler 0.4: generates brief Doxygen file header for
417 generated .h/.c files.
419 Utility yaz_iconv now supports conversion to MARC-8.
421 New facilities for the MARC module. The reading - and writing of
422 content are separate methods for the yaz_marc_t handle. The following
423 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
424 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
425 format). Write functions have prefix yaz_marc_write_.. The existing
426 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
427 available. Removed support for OAI-MARC and simplexml (not the
428 simplexml from PHP5).
430 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
431 to be returned for this connection.
433 --- 2.1.16 2006/03/31
435 Allow multiple languages and charsets to be specified with
436 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
437 negcharset iso-8859-1,utf-8
439 Translation of proximity nodes from CQL into PQF now works.
441 Moved to automake 1.8, 1.9.
443 Added function yaz_log_set_handler which allows a log handler to be
444 installed. This handler will be called for all log messages. Output
445 to file is also produced; but that can be disabled by passing NULL
446 fname to yaz_log_init_file.
448 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
450 For SRW (including GFS), accept application/soap+xml as content-type
453 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
454 produces NO stylesheet reference even if a default stylesheet is specified
457 --- 2.1.14 2006/03/14
459 Updated Windows package to include yazd.dll + yazd.lib for the
460 Development component.
462 If the environment variable YAZ_LOG is set, then it is used as a
463 string indicating the default level of logging to use if not
464 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
465 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
466 used as before. So, for example, to omit warnings from YAZ logging,
469 cql_transform() now map structure and other attributes before indexes,
470 so that index-specific structures and other attributes can override
471 defaults. So now a combination of mapping specifications such as:
473 index.dc.date = 1=date-modified 4=5
474 does the right thing.
476 cql_transform() now also respects the "always" mapping specification,
477 which establishes an initial set of attributes to be used for all
478 terms except where overridden by more specific attributes associated
479 with the index, relation or modifier.
481 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
482 which mode to use; one of "post", "get" or "soap" (SRW, default).
484 Fixes for yaz_iconv routines: changed trie-based character set conversions
485 to use only non-negative values for bit fields due to Sun's C compiler not
486 supporting negative values.
488 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
489 sequences where not read correctly. Fix by Rustam Usmanov.
491 Updated win/makefile to use options, settings which makes things
492 compile with VS C 2005.
494 --- 2.1.12 2006/02/01
496 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
498 In ZOOM socket code, use select instead of poll on MacOSX.
500 ZOOM-C now support client-side compilation of CQL into RPN that is
501 sent to the server, enabling CQL to be used against all Z39.50
502 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
503 ZOOM_query object, and submit it using ZOOM_connection_search().
504 The CQL-to-RPN translation uses a configuration file, the name of
505 which must be specified in the Connection's "cqlfile" option.
507 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
508 function, which takes as its start-term parameter a ZOOM_query object
509 (which may have had either CQL or RPN set into it).
512 --- 2.1.10 2005/11/29
514 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
515 GFS to support this as well. Backend handler, bend_srw_update, does the
516 update work. Code contributed by Ko van der Sloot.
518 Allow retrieval of Search Result-1 information in ZOOM by the use of
519 options that are attached to a result set. ZOOM documentation updated
522 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
523 UTF-8 conversion. Patch by Raj Patel.
525 Added option -m to GFS to control formatting of timestamps in log file.
527 Added 'exit' as synonym for 'quit' in yaz-client
529 Added support for specifying SRW resultSetId + resultSetIdleTime in a
530 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
531 for the new members. Patch by Ko van der Sloot.
533 Added support for SRU POST. It is supported for content-type
534 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
536 Do not build the separate Multi-threaded (MT) library libyazthread.la.
537 Instead make the library libyaz.la multi-threaded. Threading as a whole
538 can still be disabled by configure option --disable-threads. Previosly,
539 with older GLIBCs there were problems with MT libs under Apache. This
540 has now been fixed a long time ago.
542 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
545 CQL module modified to be case insensitive for relations/indexes/operations.
547 Fixed bug in CQL transform code: incorrect value relationModifieder
550 Added 'show all' command for yaz-client which retrieves all results
553 Added new yaz-client, xmles, which takes a (private) OID and
554 a document to be sent as an extended service request.
556 Describe new yaz-client commands wait_response and set_auto_wait.
558 Increase TCP/IP listener backlog from 3 (which I am guessing was
559 copied from the SunOS manual entry way back when) so SOMAXCONN, so
560 that the socket will queue as many incoming connections as it's able
561 to handle ongoing connections. In other words, it will never now
562 refuse a connection that it would be able to handle merely because
563 it's not got around to accepting() enough of the pending connections
564 yet. This is the behaviour anyway under Linux, where the listen()
565 argument is ignored; but not under BSD and on systems such as
566 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
567 YAZ-based servers should now be uniform across operating systems in
570 yaz-marcdump uses 64-bit file access on some systems. This is enabled
571 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
572 This allows yaz-marcdump to read large MARC batches (>2 GB).
574 Modified all YAZ source files - except the source which is auto-generated
575 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
578 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
579 corresponding to the existing *_setl() function. These allow option
580 values containing arbitrary valuues.
582 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
583 ZOOM_resultset_sort() in new applications. Its behaviour is identical
584 except that it returns an indicator of whether or not the sort
585 criterion was accepted (0 for OK, -1 for invalid).
589 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
590 MARC output rather than returning "new" buffer.
592 yaz-client warns about unknown init options.
594 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
598 Added support for SRW sort in Generic Frontend Server. Patch
599 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
600 sortKeys - or NULL if none is provided.
602 Fixed bug #307: It was impossible to specify indefinite/no timeout
603 for ZOOM_event. Special timeout value -1 now means indefinite timeout
606 Added support for multiple languages and charsets to be specified in
607 ZOOM. Each charset/language is separated by a blank. If negotiation is
608 in effect in init-response, Option
609 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
610 Code based on patch by Vasiliy Osadchuk.
612 Fixed bug #306: infinite recursion that occurred when calling
613 yaz_log_level_init as the first call (before other log level or
616 Fixed bug in scan handling in front end server: if preferred-Position-In-
617 Response was non-present, a NULL pointer referece was performed.
621 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
622 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
623 now defined for all those error codes. So instead of putting 109 in
624 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
625 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
627 Modified the yaz-marcdump utility to skip garbage bytes between MARC
630 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
632 Program yaz-client now exits and produces an error message if multiple
633 Z39.50 servers are specified on the command line (none or one allowed
636 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
641 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
643 Fixed bug #272: Preserve spacing for CCL terms.
647 Added support for virtual hosts and multiple backend servers for
648 the YAZ frontend server. The configution is XML based and
649 support specificition of CQL to RPN mappings and explain information.
650 See section "Virtual Hosts" in the YAZ manual.
652 Extended OPAC display utility. OPAC display utility renders
653 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
654 to supplement yaz_marc_decode_wrbuf.
656 Fixed a bug in MARC decoder that could caused it to crash for some
657 invalid MARC records. More diagnostics and warnings where added in
658 XML output (warnings, etc are stored in comments).
660 --- 2.0.34 2005/02/08
662 Fixes for UNIX domain sockets. Bug #261.
664 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
666 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
667 Added yaz_marc_subfield_str which defines subfield lead string which is
668 used in YAZ_MARC_LINE format. Default string is blank+$. Added
669 yaz_marc_endline_str which defines end of fields string used in
670 YAZ_MARC_LINE format. Default string is newline.
672 Experimental support for MarcXChange. This format can be produced
673 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
674 http://www.bs.dk/standards/MarcXchange.xsd
676 Added yaz-client commands scansize that sets maximum number of
677 entries to be returned by scan.
679 --- 2.0.32 2005/01/11
681 Added support for SRW scan in yaz-client and Generic Frontend Server.
683 * Added whereInList member to SRW Scan Term.
685 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
687 Fixed NMEM system to return aligned blocks on the smallest boundaries
688 that are suitably aligned for all possible types on the particular
689 architecture YAZ is being built for.
691 --- 2.0.30 2005/01/04
693 Fixed numerious warnings that was issued with newer versions of GCC.
695 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
696 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
699 Make YAZ Generic Frontend Server slightly faster.
701 Enhance (and reduce) logging for Generic Frontend Server.
703 Revert YAZ log system so that it flushes every write operation
704 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
706 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
707 instead of LOG_, due to name clash with syslog(3). LOG_ are still
708 present. New applications should define YAZ_USE_NEW_LOG=1 - this
709 will effectively disable old definitions.
711 --- 2.0.28 2004/11/09
713 Added yaz_log_time_format which specifies log format using
716 Added yaz_log_module_level which returns mask for a module. Value
717 is non-zero mask a if module is enabled; zero if disabled.
719 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
720 in include/yaz/cql.h.
722 Fixed bug #176: Dont throw diagnostics on empty SRU args.
724 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
726 Fixed bug #172: RPM builds does not enable SSL.
728 Doxyfile.in part of dist. Doxyfile generated by configure.
730 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
731 are given and the corresponding component does not exist.
733 Extend CCL documentation in YAZ reference. Describe r=r.
735 --- 2.0.26 2004/10/01
737 Fixed MARC->MARCXML conversion to properly deal with
738 fields, subfields, indicators having non-ASCII characters.
740 Fixed MARC->MARCXML conversion so that ASCII control characters
741 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
744 Added YAZ GFS support for conversion from Z39.50 surrogate
745 diagnostics to SRW surrogate diagnostics.
747 Bug fix: YAZ GFS did not return schema in explainResponse.
749 --- 2.0.25 2004/09/30
751 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
752 now converts recordSchema to elementSetName as well as schema URI.
754 Fixed bug in COMSTACK that prevented HTTP request packages from being
757 --- 2.0.24 2004/09/29
759 Added CCL facility r=r "range" which is similar to r=o "ordered" but
760 does not require white-space before and after the dash in a range, e.g.
761 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
764 Fixed a few AC_TRY_LINK configure tests that did not operate properly
765 due to new GCC removing "redundant" code.
767 Added yaz-client commands scanpos and scanstep that sets preferred
768 position and step-size for scan.
770 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
772 Added CCL utility ccl_qual_buf which parses one or more CCL
773 spec lines in a buffer.
775 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
776 of name and value - ignoring empty lines and comments.
778 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
780 Added odr_get_element_path which returns current element path for an
781 ODR handle. This utility is useful in error handling or user-defined
784 Added ODR_PRINT utility odr_set_stream which is is a more generic
785 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
786 to a write function and pointer to close function. The close function - if
787 non-NULL - will be called during odr_destroy.
789 Fixed bug in CCL parser where truncation char was not removed from
790 right side when truncation=both was in effect.
792 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
795 --- 2.0.23 2004/08/11
797 Fix buffer overrun in CQL parser when dealing with proximity (%).
799 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
800 to UTF-8/UCS conversion is now only based on codetables.xml.
802 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
804 --- 2.0.22 2004/08/06
806 Add support for more "commit changes" in ZOOM (uses Extended Services).
808 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
811 Yet another small fix for configure of SSL.
813 --- 2.0.21 2004/05/14
815 Fix SSL libs for configure when --with-openssl=DIR is given.
817 --- 2.0.20 2004/05/10
819 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
821 SSL comstack now uses yaz.pem certificate file on server side
822 by default. Certificate filename can be configured by calling
823 comstack function cs_set_ssl_certificate_file before cs_bind is used.
825 Fix bug regarding multiple calls to ZOOM_connection_connect.
827 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
829 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
830 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
832 ZOOM now allows inspection of X509 peer certificate for verification.
833 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
835 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
836 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
837 as "modular" but it simplifies things.
839 Added cs_get_peer_certificate to that returns peer X509 PEM.
841 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
842 NULL if SSL is unavailable.
844 Documentation about MARC decoding tools.
846 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
848 --- 2.0.19 2004/03/30
850 Rename CHANGELOG to NEWS to follow GNU style packing.
852 Fix bug with missing initialization of member in init_diagnostics.
853 This bug affects threaded version of GFS server.
855 --- 2.0.18 2004/03/20
857 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
860 Ensure zlib.dll is packed with Windows install.
862 --- 2.0.17 2004/03/17
864 Fix encoding of xsd:string to use text instead of CDATA.
866 Fix endless loop in CQL parser with unbalanced ".
868 Use a more compact way to store MARC-8 conversion tables.
870 --- 2.0.16 2004/03/16 Debian only
872 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
875 Update CQL parser to use new CQL 1.1 modifiers for booleans and
880 --- 2.0.15 2004/03/01
882 Another fix for decoding of XML packed records.
884 --- 2.0.14 2004/02/25
886 Fixes for Chunked encoding. White space not ignored after length spec.
888 Update NS and use default NS for SRW diagnostic elements.
890 --- 2.0.13 2004/02/23
892 Implement ZOOM_resultset_cache_reset which resets record cache.
894 Implement ZOOM_resultset_sort which sorts a result set.
896 Implement chunked HTTP transfer.
898 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
900 --- 2.0.12 2004/02/16
902 Added member 'schema' to bend_explain_rr structure so that backend
903 can specify explain record identifier. Defaults to Zeerex 2.0.
905 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
907 --- 2.0.11 2004/02/16
909 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
912 Added init command for yaz-client which sends "extra" init request.
914 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
915 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
917 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
919 Make ZOOM error code for "invalid query".
921 Fixed compilation for SSL which wasn't properly enabled for all platforms.
923 --- 2.0.10 2004/02/05
925 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
928 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
930 Added option -p <file> to make Generic Frontend Server to write PID file.
932 Added option -D to put Generic Frontend Server in background on its own.
934 Make ZOOM C recognize option "password". If unset, "pass" is used
935 (for backwards compatibility).
937 Fixed a bug in Generic Frontend Server that could make it crash if a
938 client sets characterSetNegotation bit, but didn't pass negotiation stuff
941 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
942 Must be issued before open, in order to be in effect.
944 --- 2.0.9-6 2004/01/12 Debian/Windows
946 Make the SRU server more picky WRT unknown params, etc.
948 Bug fix: ZOOM scan response didn't return displayTerm - when present.
950 New YAZ client command, options, that sets Z39.50 options.
952 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
953 options from a string of tokens (one token for each option bit).
955 Update SRW diagnostic code messages.
957 --- 2.0.9-5 2004/01/07 Debian/Windows
959 Handle user defined stylesheet for SRW/SRU.
961 --- 2.0.9-4 2004/01/06 Debian/Windows
963 Fix bug in decoding of Content-Length.
965 --- 2.0.9-3 2004/01/06 Debian/Windows
967 Fix a bug with decoding of XML packed records.
969 --- 2.0.9-2 2004/01/05 Debian only
971 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
973 Fix bug in SRW/SRU diagnostics decoding.
977 Fixed bug in Generic Frontend Server which could drop records exceeding
978 preferred message size. Reported and fixed by Irina Dijour.
980 Fixed calculation of package size for structured records in Generic
981 Frontend Server. Reported and fixed by Irina Dijour.
983 Fixed namespace for SRW/SRU diagnostics.
985 Fixed SEGV in yaz-client that occured for HTTP connection errors.
989 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
990 this version is incompatible with version 1.0 and older YAZ SRW/SRU
993 CQL changes to reflect recent changes to the specification:
994 * Documentation talks about context sets instead of index sets.
995 * Documentation talks about indexes instead of qualifiers.
996 * The CQL-to-PQF transformer's configuration file now uses
997 "index.set.name = <attributes>" instead of the old form
998 "qualifier.set.name = <attributes>". (Both forms are still
999 understood but the latter is deprecated.)
1000 * CQL terms with no explicit index specified are now interpreted as
1001 cql.serverChoice instead of srw.serverChoice (which of course
1002 behaves exactly the same.)
1004 --- 2.0.7 2003/12/16
1006 MARC conversion can now generate ISO2709 output in another
1007 character set. yaz-marcdump uses this facility if you invoke it
1010 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1011 functions from there can be used from C++.
1013 --- 2.0.6 2003/12/04
1015 Frontend server now transfers memory from decoded packages to stream
1018 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1019 references to show up.
1021 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1022 the ZOOM Abstract API. The older names for the same options are still
1023 also supported for the benefit of old applications.
1025 ZOOM-C supports "implementationId" and "implementationVersion" options
1026 to go along with "implementationName". These allow the user code to
1027 specify identification strings to be sent to servers.
1028 Add OID for the new ExtLite attribute set.
1030 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1031 as requested/supplid by Ere Maijala <ere@atp.fi>
1033 For generic frontend server, reverse the order of
1034 "toolkit-supplied / application-supplied" strings sent as implementationId,
1035 Name and Version. Also, remove the spaces around the slash. This brings
1036 the GFS in line with the behaviour of ZOOM-C on the client side.
1038 Add function ZOOM_scanset_display_term.
1040 yaz-client shows scan displayTerm if present.
1042 Utility yaz-iconv is now installed by default along with the man page
1045 Extend configure check for OpenSSL to use pkg-config where available (such
1048 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1049 server to specify uid/gid/mask for socket using the format
1050 unix:[user=uid,][group=gid,][umask=mask,]file=path
1051 If file= is omitted the existing format is assumed, e.g.
1053 in which case the mask is 0666 (rw for everybody).
1055 Major restructure of YAZ source. All source in libyaz is in src directory.
1056 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1057 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1059 Added man page for utility yaz-marcdump (used to be called marcdump).
1060 yaz-marcdump is installed by 'make install'.
1062 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1063 of incoming package failed.
1065 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1067 Change prototype of odr_perror: add const to message string.
1069 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1071 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1072 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1073 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1074 DNS lookup. There should not be any compatibility problems with this
1075 assuming that blocking=1 or 0 is used.
1077 Fix bad reference in UNIX comstack in function cs_addrstr.
1079 Fix for compilation on AIX.
1081 The generic front-end server (server/seshigh.c) now supports returning
1082 Init diagnostics to the client in User-information-field, in
1083 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1086 --- 2.0.4 2003/09/04
1088 Allow any CQL relation (not just all,any,exact,scr).
1090 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1091 that features the same UI.
1093 Implemented command update0 in YAZ client which is equivalent to
1094 update but uses old of Ext Update ASN.1.
1096 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1097 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1098 Previously no OID was used for this info.
1100 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1101 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1102 returns 'malformed search term' otherwise.
1104 SortResponse member resultCount now set to NULL in sort handler of
1107 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1110 Add three new utility functions for translating OIDs between various
1111 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1112 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1113 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1114 char *oid_to_dotstring(const int *oid, char *oidbuf);
1115 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1117 Reverted modifications for ES Update definition for z_IU0Update
1118 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1119 is back to YAZ 2.0.2.
1121 String value attributes for CCL parser.
1123 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1124 which their FirstSearch server returns in Init responses, sometimes
1125 carrying useful diagnostic information when Init fails. This has the
1126 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1127 "z39.50/oclcui.asn", where its definition is somewhat different from
1128 what OCLC document on their web-site, as required to interoperate with
1131 Support for anonymous authentication in yaz-client. Use the command
1134 * Fix the OID of the Index Data-local "admin" Extended Service from
1135 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1136 the 1000, which indicates a locally-defined OID, was a mistake.
1138 --- 2.0.3 2003/06/20
1140 Fix CCL directive @case handling so that it affects string match for
1141 both CCL keywords and qualifiers.
1143 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1144 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1145 Decoder has been updated with ASN.1 changes as listed in
1146 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1147 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1148 z_IUUpdate, remains unchanged.
1150 ZOOM_record_get may now return a record in a specific character set.
1151 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1152 "from" is the character set of record as returned by target. "to" is
1153 the character set to be returned. If omitted, "to" is UTF-8.
1155 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1157 New ODR utility, odr_getelement, which returns name of element for
1158 which encoding/decoding failed.
1160 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1161 in cases where a required element was omitted.
1163 Bug fix: some MARC8 sequences were not converted.
1165 New ZOOM option "step" which specifies number of records to be
1166 retrieved in one chunk. Used in conjunction with "start" and "count".
1168 SRW support for yaz-client. Use scheme http: to use it, e.g.
1171 yaz-client no longer does (un)intelligent character set conversions
1172 by default. Can be enabled with charset and marc_charset commands.
1174 xmalloc trace fix for 64-bit systems such as DEC alpha.
1176 Solaris 2.6 compile fix.
1178 New function, cql_strerror() translates SRW error codes, as returned
1179 by cql_transform_error(), into human-readable English strings. Used
1180 in yaz-client diagnostics when appropriate.
1182 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1183 converts it into a type-1 query which is sent to the server. This
1184 makes CQL available for use with all Z-servers, as opposed to the tiny
1185 minority that can handle CQL queries themselves.
1187 --- 2.0.2 2003/04/28
1189 New Debian package layout similar to the Redhat Package layout.
1191 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1192 and search result respectively.
1194 --- 2.0.1 2003/04/25
1196 Redhat package is now several packages: libyaz (runtime libraries),
1197 libyaz-devel (development and documentation, and yaz (utility programs).
1198 Package spec file by Morten Bøgeskov.
1200 New member 'schema' in struct bend_fetch_rr which the name of requested
1201 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1202 handler MAY set this to reflect the schema of the returned record.
1204 New member 'display_term' in struct scan_entry. GFS now sets member entries
1205 and allocates scan entries to be filled by user scan handler. In previous
1206 version, entries member was allocated by the scan handler. That still works,
1207 but the GFS will ignore member display_term - assuming it was NOT set by
1208 the handler. The fact that the GFS now allocates the entries both allows
1209 for new members and makes a scan handler easier to write.
1211 Fix CQL lex buffer overflow.
1213 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1214 SRU default recordPacking is string.
1216 SRU protocol support for frontend server.
1218 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1220 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1222 Added scan for the ZOOM shell (zoomsh).
1226 * String Identifers for Schemas (Amendment 5).
1227 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1228 Old definition for schema
1229 Odr_oid *schema; /* OPT */
1234 Z_InternationalString *uri;
1235 #define Z_Schema_oid 1
1236 #define Z_Schema_uri 2
1239 * resultCount parameter to Sort Response (Amendment 1).
1240 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1242 Support for SRW 1.0 over HTTP. This is an optional feature and
1243 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1246 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1247 on the same port. SRW SearchRetrieveRequests are mapped
1248 to bend_init,bend_search,bend_fetch,bend_close.
1250 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1252 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1253 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1255 ZOOM connections are SRW based if schem http is used for hostname
1256 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1257 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1259 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1260 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1261 distance=n, order=true/false, relation=le, prox unit=word. If
1262 n is omitted, distance 1 is used.
1264 Fixed problem with C compiler include path in wrong order.
1266 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1267 on Solaris. Patch from Ko van der Sloot.
1269 New MARC decode API. All new functions operate on a yaz_marc_t
1270 handle. The most important new functions are: yaz_marc_create,
1271 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1272 decode and destroy respectively. Decoder can produce formats
1273 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1274 include/yaz/marcdisp.h.
1276 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1277 to UTF-8, UCS-32, wchar_t or Latin-1.
1279 * Prototypes for yaz_iconv_-functions moved to separate header
1280 include/yaz/yaz-iconv.h.
1282 Make a few private functions 'static' in unix.c. This prevents
1283 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1285 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1286 are set when Init Response is received.
1288 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1289 but returns diagnostic set as well.
1291 New function yaz_strerror which is a portable wrapper for
1292 strerror/strerror_r/GetLastMessage.
1294 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1295 is returned for MARC. If type is "oai", then OAI MARC is returned.
1297 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1300 --- 1.9.2 2002/11/26
1302 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1304 Fix bad race conditions on SIGTERM and terminate gracefully in
1307 Move retrieval (data1) module to Zebra since nobody seems to be
1310 Add GRS-1 render for ZOOM using same format as yaz-client.
1312 --- 1.9.1 2002/10/05
1314 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1316 Fix broken ESpec handling in data1 module.
1318 SGML reader parses comments and makes them part of the data1 tree.
1320 Added several type casts so that YAZ compiles as C++ code.
1322 ZOOM didn't handle PDU encoding failures properly.
1324 Added more Bib-1 diagnostics (approved extensions).
1326 GNU configure: better check for iconv.
1328 More portable use of accept, getpeername. Check for socklen_t. Use
1329 int/size_t if socklen_t is not defined.
1333 PQF parser rejects bad queries - including those with extra
1334 characters in them. PQF parser used to silently ignore that.
1335 Cleaner API for PQF added, which allows you to get detailed
1336 error information for bad queries (see yaz/pquery.h).
1338 Fixed bug in ZOOM_record_get for type "database".
1340 Implemented mini iconv library supporting conversions between
1341 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1343 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1345 --- 1.8.9 2002/08/20
1347 Fixed ZOOM C record cache so that preferredRecordSyntax and
1348 elementSetName is used to check for already fetched records.
1350 --- 1.8.8 2002/08/02
1352 Added three members in bend_initrequest structure to facilitate
1353 character set negotiation.
1355 Fixed a bug in frontend server that could cause indefinite
1356 loops under rare conditions.
1358 Revised character set utilities (charneg.h) so that encoding
1359 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1361 For PQF, directive @term <type> sets term type for Scan/Search.
1362 Here <type> is general, string, numeric, null. The term type
1363 is inherited - just like @attr.
1365 New call odr_set_charset that sets character set conversion for
1366 international-strings on a ODR stream. Prototype is:
1367 int odr_set_charset(ODR o, const char *to, const char *from);
1368 The InternationalString is still represented as C string in YAZ
1369 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1370 won't). On the protocol level, you can use any encoding.
1372 Support for UNIX sockets in ZOOM.
1374 Solaris recv sometimes returns errno == ENOENT. It is treated as
1375 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1377 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1378 both client and server. Code by Morten Bøgeskov.
1380 --- 1.8.7 2002/05/22
1382 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1383 that they can be used directly from Visual Basic. You must recompile
1384 your windows APP if you're using ZOOM.
1386 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1387 Commands "lang" and "charset" sets language and character set respectively.
1388 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1389 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1391 Attributes from multiple CCL fields may be OR'ed rather than merged
1392 using directive "@field or". Fields are still merged by default -
1393 equivalent to "@field merge".
1395 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1398 Fixed bug in zget for parameter ExtendedServicesResponse.
1402 --- 1.8.6 2002/03/25
1404 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1406 Client displays USR.1:SearchResult-1 (hits per term).
1408 Additional Search Info for search in Generic Frontend Server.
1410 Fixed CCL parsing of "field=s".
1412 WIN32 installer - using the excellent NSIS software from nullsoft.
1414 Fixed CCL parsing of "field = - <number>".
1416 Added function yaz_marc_decode that decodes MARC for line mode
1417 display or XML (similar to that used by JZKit).
1419 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1420 Z39.50. But ISO/ILL was, however.
1422 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1423 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1425 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1426 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1428 --- 1.8.5 2002/02/03
1430 New YAZ client features: Command completion and new commands:
1431 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1432 Code provided by Jacob Poulsen.
1434 New call oid_trav, that visits all registered OIDs via callback.
1436 Function ZOOM_record_get now returns const char pointer rather than
1437 void pointer. It saves a lot of type casts.
1439 For YAZ client, command "auth" now allows you to set authentication
1440 in IdPass style. It is enabled when three tokens are given - order
1441 is user, group and password.
1443 Fix memory leaks in MARC record handling for ZOOM.
1445 New option for YAZ client, -k <kilobytes> that sets
1446 maximum record size. Similar to -k option for generic frontend
1447 server and yaz-ztest.
1449 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1451 Prefix query parser reports "fail" when bad attribute set is given.
1453 Fix in MARC decoder. Proximity logging. Fix for attribute set
1454 in scan handler for server. Patches by Shigeru Ishida.
1456 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1459 Configure option --with-openssl=<dir> now works when a directory is
1460 specified. Patch provided by Morten Bøgeskov.
1462 New option for YAZ client, -u <auth>, that sets authentication.
1464 ZOOM fix: error information was sometimes "missing", since error
1465 was cleared/reset too when it shouldn't.
1467 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1469 --- 1.8.4 2002/01/04
1471 Scan for ZOOM API. New object ZOOM_scanset. New functions
1472 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1473 ZOOM_scanset_destroy.
1475 New ZOOM function, ZOOM_connection_last_event, that returns type
1476 of last event (such as "receive data", "send data", "apdu received",
1479 New ZOOM option, schema, that specifies schema for retrieval.
1481 New CCL feature. Qualifiers can be aliases for one or more
1482 other qualifiers (if more than one is given, OR is used).
1484 ZOOM uses named result sets if target supports it.
1486 Two new YAZ client commands: . (dot, which sources a script of YAZ
1487 client commands), and ! (to execute shell command.). Implemented
1490 Working on Debian packages.
1492 --- 1.8.3 2001/11/19
1494 YAZ client enables named result sets only if target supports it.
1496 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1498 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1499 with key="host" to get same result.
1501 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1502 Function Z3950_resultset_record(s) returns references to records
1503 "owned" by resultset. To become owner use Z3950_record_clone.
1505 Function z_ext_record handles Extended Services. Thanks to
1508 --- 1.8.2 2001/11/12
1510 CCL Parser fix: ignore token comma when dealing with and-lists.
1512 Documentation updates for COMSTACK.
1514 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1515 Changed prototype Z3950_records. For some functions, int parameters
1516 were changed to size_t.
1518 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1521 New MARC decode/display function, marc_display_exl, which properly rejects
1522 non-ISO2709 records. YAZ client uses it.
1524 --- 1.8.1 2001/10/29
1526 Fix bug: local attribute set wasn't set correctly in PQF strings.
1530 * Old Z39.50 codecs no longer supported.
1532 Added ZOOM C binding. See http://zoom.z3950.org/
1534 Renamed states for COMSTACKs to avoid confusion with events.
1536 Implemented cs_look and proper cs_rcvconnect.
1538 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1540 Configure detects POSIX threads on OpenBSD.
1542 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1543 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1545 When error is returned from present handler, non-surrogate diagnostic
1546 is returned in present response (and fetch handler is no longer called).
1548 * Minor adjustments to pquery parser (PQF). Token characters may be
1549 escaped by using backslash (C-style).
1551 PQF parser allows string attribute values to be specified. For @attr,
1552 non-numeric characters after the equal-sign are treated as strings
1553 (e.g. @attr 9=title).
1555 CCL trunction character may be defined (@truncation in file)
1557 * function zget_ExtendedServicesRequest sets waitAction to
1558 waitIfPossible (was wait).
1560 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1563 CCL operator names may be set in field definition files (CCL_bibset).
1564 See ccl/bib1 for an example.
1566 Fixes in ASN.1 compiler for C++ compatibility.
1568 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1569 and "op_or" to avoid conflict with C++.
1571 Fixed problem with GNU readline detection on Redhat 7.0.
1573 Added step-size for Scan backend handler.
1575 Fixed bug that made the frontend server crash when no attribute
1576 set was specified for scan.
1578 Front-end server automatically switches to original working directory
1579 when installed as an NT service. Previously -w had to be specified to
1582 Added extended attributes for retrieval module (data1), so that data1
1583 records carry d1_readXML/SGML attributes. d1_read also supports
1584 null-data rules ( <tag/>)
1586 On UNIX when POSIX threads are available, a separate library libyazthread
1587 is created. Programmers should link with that library and the yaz library
1588 when using threads. The reason for the split was that some applications
1589 on Linux, such as Apache, doesn't work well when using shared objects that
1592 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1593 (or any frontend server) in SSL mode by specifying ssl: followed by
1594 address. Only tested on UNIX.
1596 Added feature for CCL module. Virtual structure s=al or s=ol generates
1597 and-list and or-list respectively instead of phrase search.
1601 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1602 log_mask_str. This was done to avoid name conflicts with other libraries
1603 (such as other PHP extensions).
1605 Added raw OID member for preferred record syntax (request_format_raw)
1606 and returned record syntax (output_format_raw) for backend fetch method.
1608 Config file yaz-config now accepts options so that it returns specific
1609 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1611 Shared library support for UNIX using GNU libtool.
1613 * Modified backend interface. Request/Response struct's replaced by
1614 one read/write C struct. For example bend_fetchrequest and
1615 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1616 Every handler - even search has to be registered in bend_init
1617 handler. This means that the YAZ library no longer refers to
1618 external functions and it makes it possible to make the whole
1619 thing a single DLL/SO.
1621 Added Segment handler for backend server.
1623 Added Zmbol/Zebra administrative functions to YAZ client.
1625 Threaded frontend server on UNIX (when POSIX Threads are available).
1626 Starting the server with option -T enables multi-threading.
1630 Added configure option --enable-comp/disable-comp to control use
1631 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1632 located in sub directory asn.
1634 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1635 in ${exec_prefix}/bin along with the other programs yaz-client and
1638 GNU automake used to maintain makefiles.
1640 Added several OID's.
1642 Changed retrieval module so that we can load records with no abstract
1643 syntax defined. Tagpaths in these records are fully composed of string
1646 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1650 On UNIX, the generated makefile now supports a proper 'make install'.
1651 The prefix can be set via GNU configure to set the install location
1652 (default is /usr/local).
1654 * YAZ programs client and ztest were renamed to yaz-client and
1655 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1656 locations, such as /usr/bin,/usr/local/bin,etc.
1658 * YAZ Header files were moved from include to include/yaz. YAZ Header
1659 files are referred to as include <yaz/log.h> rather than <log.h>.
1660 The YAZ include path (-I ..) is therefore the same as before. Programmers
1661 should update their #include statements or use -Ipath/include/yaz
1662 instead. The main motivation for doing this change is that YAZ header files
1663 can be installed in "standard" locations /usr/include,/usr/local/include
1664 without introducing conflicts, since ALL YAZ header files are stored
1665 in subdirectory yaz (under /usr/include for example).
1667 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1668 rather than project/workspace files. We switched because project files
1669 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1672 Changed name of logging function, logf, to yaz_log, to prevent name
1673 clash with some math-log functions. The YAZ header log.h defines logf
1674 to yaz_log (#define) so there should be no incompatibilities by this
1677 Added bend_start/bend_stop handlers for server. These handler are
1678 called on start/stop of server. For windows they are called whenever
1679 a service is started/stopped.
1681 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1682 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1683 in util/yc.tcl. The auto-generated C code structures are, in a few
1684 cases, incompatible with the old decoders. There are differences in the
1685 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1686 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1687 The preprocessor variable ASN_COMPILED is defined when the compiled
1688 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1689 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1690 wish to use the old encoders/decoders you can specify --disable-yc
1693 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1694 version so that it supports both new - and old version of DB Update
1696 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1697 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1698 change. The name parameter can be set to 0 in which no name is specified
1699 for the construction. The macros odr_implicit and odr_explicit sets name
1700 parameter to zero for the construction involved. New macros
1701 odr_implicit_tag and odr_explicit_tag are similar to the others,
1702 except that a name parameter is added. For programmers' that don't use
1703 ODR they probably only need to change the call to z_APDU and z_External.
1705 Added access control facility by interfacing the TCP wrapper library.
1706 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1707 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1708 name of the daemon and enables the access control as specified in
1709 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1711 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1712 den Dool <H.M.vdnDool@kub.nl>.
1714 Added reference ID parameter to most functions in server API - refer
1715 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1717 Changed name of ccl library to libccl.a (was ccl.a).
1719 Fixed bug in decoder for Explain (Category TargetInfo).
1721 Added support for GNU readline in client. Thanks to Jacob Poulsen
1722 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1724 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1725 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1726 IMPLEMENTATION! This change was made to the development version before
1727 the ZIG decided to retract the amendment. If any users MUST be
1728 compatible with the original Update definition, PLEASE CONTACT US, and
1729 we will include a separate definition corresponding to the old Update
1730 ES. Note that because of the change to the ASN.1 of the
1731 TaskPackageRecordStructure we cannot define a single structure that
1732 will support both versions.
1734 * Added const modifier to buffer parameter for some ODR/BER encoding
1735 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1736 completeWAIS, odr_dumpBER.
1738 Fixed bug in client.c which caused a crash when a scanResponse didn't
1739 contain positionOfTerm.
1741 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1742 * will cause an error in a client if a non-YAZ target sends both a
1743 * list of Scan entries and non-surrogate diagnostics.
1745 Retrieval module enhancements. Tag sets may be typed in the reference
1746 to it. From the .abs-file the "tagset" directive takes a third optional
1747 integer type for the tag set referenced. From a .tag-file the "include"
1748 directive takes a third optional type as well. The old "type" directive
1749 in the tag set itself is still recognized but acts as the default type
1752 Backend interface change. Individual Scan terms returned from bend_scan
1753 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1754 in include/backend.h.
1756 Retrieval module enhancements. Multiple tag sets and attribute sets may
1757 be specified in abstract syntax specs. Revised the error/warning for
1758 logging messages reported by the retrieval module when reading the
1761 Object Identifier system (oid_..) changed. The API is backwards
1762 compatible but the oid-routines now allocates new OID's when needed.
1763 Raw OID's may be specified in oid_getvalbyname.
1765 YAZ now uses GNU configure to generate Makefile(s).
1767 * Minor changes in some of the member names of DeleteResultSetRequest and
1768 DeleteResultSetResponse. See include/proto.h.
1770 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1771 and added member 'languages' in TargetInfo (which was missing).
1773 Changed the way attribute sets are handled in the retrieval
1774 module. These are now cached, just like the abstract syntaxes
1777 Changed YAZ so that it links with compiled ASN.1.
1779 Added Explain-schema definitions and mapping routines. The following
1780 Explain categories have been implemented: AttributeDetails,
1781 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1783 Fixed minor bug in Windows version of Server Library.
1785 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1787 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1789 Added EXTERNAL: UNIverse Resource Report (non-standard).
1791 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1792 ENUMERATED and SET OF.
1794 * Added 'const' to some of the char pointer arguments for the
1795 functions, data1_read_node, data1_getelementbytagname,
1796 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1799 Fixed bug in data1_insert_taggeddata - the last_child member of
1800 parent wasn't initialised.
1802 * Changed data1_read_record and data1_read_node so that the supplied
1803 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1804 doesn't refer to any parts of the "SGML"-buffer.
1806 Fixed bug in server library (Windows version of statserv_remove).
1808 * Changed code so that it compiles as C++. The type definition
1809 of Odr_fun which is a member of Odr_arm was changed. The result is,
1810 that an explicit typecast is needed for the fun pointer when
1811 using Odr_arm - as in:
1812 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1814 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1816 Implemented the new structured date and time definition as approved
1817 by the ZIG. Added schemaId element to the specificTag in Espec-1
1818 (also approved at the last ZIG). Thanks to RVDM.
1820 Added some Object identifiers (RVDM).
1822 Changed the Update Extended Service (RVDM).
1824 Added command "refid" to client which specifies referenceId for
1825 the following requests.
1827 Implemented extended service handling for server. See ztest.c
1828 for an example as well as backend.h. New handlers are registerd
1829 in the Init handler.
1831 * Changed interface for sort in server.
1833 Added new members to statserv_options_block. It allows a server
1834 to read options from another source than just the command line. Thanks
1835 to Charles Woodfield.
1837 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1838 renamed to zboolean. Some C++ compilers complained about the name.
1840 Minor changes to gils.abs. Added index 's' (sort) on title
1841 and date/time-last-modified.
1843 --- 1.4pl2 1998/1/30
1845 Fixed bug in server library regarding inetd mode (-i). This bug
1846 was introduced by release 1.4.
1848 --- 1.4pl1 1998/1/29
1850 Added sort facility in client and backend server interface.
1852 Fixed problem with dependencies in Makefile(s).
1854 Fixed bugs for encoders/decoders of extended services and
1857 Implemented sub-tree feature for schemas. Sub-trees are
1858 referenced in *.abs-files. See explain.abs for an example
1859 of the use of this feature.
1861 Modified bib1.att; local attributes for ANY didn't include
1862 ANY itself (only affects use of the retrieval module).
1864 Fixed bug in plain SGML reader in function data1_read_node:
1865 tags with prefix "var" was incorrectly interpreted as variants.
1867 Added feature "sub-schemas" to enable references to - and definitions
1868 of - group of elements.
1870 * Removed member parent from type data1_element (in data1.h).
1872 Implemented function odr_nullval() that returns the value of
1875 * Removed member num_children from data1_node (in data1.h).
1877 Made NT service interface part of the server library. The
1878 function statserv_main uses the NT service when required and
1879 calls the statserv_start / statserv_close routines.
1881 Routine zget_SearchRequest and zget_PresentRequest fills
1882 resultSetName/Id member with "default" instead of "Default".
1884 Fixed memory leak in server. Request queue member wasn't freed.
1886 Fixed nmem_exit so that memory is freed.
1890 Revised the CCL parser utility to be thread safe.
1892 Added function, oid_ent_to_oid, to replace the function
1893 oid_getoidbyent, which is not thread safe.
1895 * Added nmem_init and nmem_exit to initialize and release
1896 NMEM resources. Function nmem_init should be called once in the
1897 initial thread before NMEM/ODR is used. statserv.c and client.c
1898 have been changed accordingly. The change was necessary to make
1899 NMEM thread safe. The NMEM memory pool is shared amongst threads
1900 in a process. Unix-based applications will still work fine without
1903 Added NT Services interface for the the Z39.50 (statserv) Server.
1904 Refer to the ztest.c source on the usage.
1906 Windows 95/NT port using MSVC5.0. Project files are included in the
1909 * Defined new 'global' handle for the retrieval (data1) system. The
1910 new handled, data1_handle, describes the state of the data1 system.
1911 This handle is passed as first argument to virtually all
1912 data1 related routines. The functions data1_create and data1_destroy
1913 creates and destroys a data1 handle respectively.
1915 Added ODR encode stream member to all backend request structures
1916 init, search, scan etc. This stream should be used to allocate all
1917 memory used for the response when thread safe operation is needed.
1919 Changed the comstack utility, cs_addstr, to be thread safe. The
1920 returned hostname string returned by the function is now part the
1923 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1924 function. The cs_straddr takes a COMSTACK handle as argument, so this
1925 function must be used after cs_create and before bind/connect.
1926 This function is thread safe.
1928 Moved test server to 'ztest' directory - generic server code still
1929 in 'server' directory.
1931 Made prefix query (pquery.c) utility thread safe.
1933 Added new function modifier YAZ_EXPORT to 'export' public DLL
1934 functions when using windows (see include/yconfig.h).
1936 Added definitions to the OID database (util/oid.c) (RVDM).
1938 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1940 Added call to ccl_rpn_delete in client program.
1942 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1943 release of RPN structure.
1945 Added support for C++, headers uses extern "C" for public definitions.
1946 With input from RVDM.
1948 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1949 Thanks to Ronald van der Meer (RVDM).
1951 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1953 Added support for private extensions to the OID database
1954 (oid_setprivateoids()). Thanks to RVDM.
1956 Added optional, physical ANY (key replication)
1958 Fixed null-reference problem in GRS-1 output filter.
1960 Proximity operator added to Prefix Query Format (PQF).
1962 In test client command "base" accepts multiple databases.
1964 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1968 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1970 Smallish bug-fixes in the new encoders/decoders (explain).
1972 Bug fixed in DeleteRequest.
1974 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1976 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1978 Added SOIF syntax (using private OID for now) to retrieval module and client.
1980 Added Update extended service.
1982 Added SearchResult-1 additional info structure.
1984 Added optional CCL (ISO8777) interpreter as separate module. Available
1987 --- 1.2 1996/6/10 (1st anniversary release)
1989 Added Summary record syntax. Lightly tested.
1991 Added OPAC record syntax. Untested.
1993 Added ResourceReport service encoders/decoders. Untested.
1995 Fixed bug in z_Unit - wrong tagging on unitSystem.
1997 Fixed bug in the DiagRecs decoder.
1999 Added options for max PDU size and session timeout to frontend-server.
2001 Added documentation of query-language parsers and other supporting utilities.
2003 [frontend-server] Added Attribute set to the bend_scanrequest API.
2005 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2006 surrogate diagnostics were generated.
2008 [retrieval] Allow multiple local values for attribute.
2010 [retrieval] Allow multiple attributes per element in .abs files. index type.
2012 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2014 --- 1.1pl2 1996/4/10
2016 Minor changes, mostly specific to Zebra's requirements (retrieval)
2020 Repaired bug in frontend server when running multiple listening
2021 endpoints in dynamic mode.
2023 z_External() now won't break if a known, ASN.1 value comes encapsulated
2024 in an octet-string. The value will pass through unmodified in an Odr_oct.
2026 Added a bit of code to the demo client to decode & display
2027 ASN.1-structured records represented in the octet-aligned branch of
2028 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2030 Added z_ext_getentbyref() to the ASN module. Doc updated.
2032 * Completed the SCAN definition in the ASN module. This may break SCAN
2033 code based on older YAZ-versions at compile-time. The fix is easy -
2036 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2037 under the SCAN definition. Remember to initialize this, server-people.
2039 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2040 that this does not extend to ODR and ASN.
2042 Comstack allows insertion of established socket (primarily for
2043 inetd-operation of servers). Doc updated.
2045 Front-end server can now start from the inetd in TCP mode. Doc
2048 --- 1.0pl4 1996/1/24
2052 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2053 the rank and record number.
2055 Adjustments to the frontend server.
2057 Fixed diagnostic BER dumper. It ignored the file argument.
2061 Various changes to retrieval module.
2063 Changed the union discriminators of the protocol files from enums to
2064 ints paired with #defines.
2066 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2069 *Changed operator in the RPN structure to 'roperator', again to avoid a
2072 Fixed problems in Explain decoders/encoders.
2074 --- 1.0pl2 1995/12/6
2076 Memory bug in log module fixed.
2078 --- 1.0pl1 1995/12/5
2080 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2082 Bug in Explain DatabaseInfo module fixed.
2084 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2088 The shift to v1.0 signals that we now consider the *core* functionality
2089 of YAZ reasonably stable (the core being more or less equivalent to
2090 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2091 tested (Explain not at all - though that will happen soonish).
2093 Minor changes to code to support Windows port.
2095 Various minor changes after we're getting to use GRS-1 & co. more.
2097 Added Espec-1 format.
2099 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2100 of the protocol and it cannot be selected when encoding (maps into 'string'
2101 when decoding). Needed to talk to some servers.
2103 Demo client can request simple element set names.
2105 Added Diagnostic Format encoders/decoders.
2107 Added simple Close handling to frontend server (no hooks for resource
2108 reporting yet), and demonstration client.
2110 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2112 --- 1.0b3 1995/08/24
2114 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2115 handled incorrectly when records were requested in the searchResponse. This
2116 will only affect you if you use the frontend-server.
2118 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2119 Test-client will ask for and print GRS1. Ztest will return dummy records
2122 Added Explain encoders/decoders to the service-level API. Untested.
2124 Added Extended Services: Item Order encoders and decoders to the Service-
2125 level API. Untested. We could use a recent copy of the pertinent bits
2126 of the ILL protocol to add those bits.
2128 Added diagnostic format 1 encoders/decoders to the service-level API.
2131 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2132 odr_cons.c, which causes a more correct output.
2134 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2135 was always set to 0 when no records were requested in the searchRequest.
2137 * Added better external-handling. This shouldn't harm old code that
2138 *encodes* externals. It can break code that looks for a
2139 'single-ASN1-type' representation, since those types that are known
2140 are now decoded immediately. Look at the SUTRS sample code in
2141 seshigh.c and client.c. Documentation updated.
2143 Handling of structured records in bend_fetchresponse. Length -1 marks
2144 structured record, type is deduced from format field.
2146 --- 1.0b2 1995/06/27
2147 Fairly quick maintenance release to add SUTRS support.
2149 Fixed handling of SUTRS records in the demonstration client.
2151 * Added format field to the bend_fetchrequest and bend_fetchresponce
2152 structures of the backend API (frontend server). When the record is
2153 returned, the value of the format field is mapped to an OID. The
2154 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2155 of the record. The special value VAL_NONE in the bend_request means
2156 that no specific format was requested by the client. Documentation
2157 updated accordingly. Test server (ztest) will return a fixed dummy
2158 SUTRS record if your client requests SUTRS.
2160 Documentation updated accordingly.
2162 You can now set external libraries and RANLIB support in the top-level
2166 First public release.
