3 Allow multiple languages and charsets to be specified with
4 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
5 negcharset iso-8859-1,utf-8
7 Translation of proximity nodes from CQL into PQF now works.
9 Moved to automake 1.8, 1.9.
11 Added function yaz_log_set_handler which allows a log handler
12 to be installed. This handler will be called for all log messages.
13 Output to file is also produced; but that can be disabled by passing
14 NULL fname to yaz_log_init_file.
16 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
18 For SRW (including GFS), accept application/soap+xml as content-type
21 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
22 produces NO stylesheet reference even if a default stylesheet is specified
27 Updated Windows package to include yazd.dll + yazd.lib for the
28 Development component.
30 If the environment variable YAZ_LOG is set, then it is used as a
31 string indicating the default level of logging to use if not
32 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
33 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
34 used as before. So, for example, to omit warnings from YAZ logging,
37 cql_transform() now map structure and other attributes before indexes,
38 so that index-specific structures and other attributes can override
39 defaults. So now a combination of mapping specifications such as:
41 index.dc.date = 1=date-modified 4=5
44 cql_transform() now also respects the "always" mapping specification,
45 which establishes an initial set of attributes to be used for all
46 terms except where overridden by more specific attributes associated
47 with the index, relation or modifier.
49 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
50 which mode to use; one of "post", "get" or "soap" (SRW, default).
52 Fixes for yaz_iconv routines: changed trie-based character set conversions
53 to use only non-negative values for bit fields due to Sun's C compiler not
54 supporting negative values.
56 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
57 sequences where not read correctly. Fix by Rustam Usmanov.
59 Updated win/makefile to use options, settings which makes things
60 compile with VS C 2005.
64 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
66 In ZOOM socket code, use select instead of poll on MacOSX.
68 ZOOM-C now support client-side compilation of CQL into RPN that is
69 sent to the server, enabling CQL to be used against all Z39.50
70 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
71 ZOOM_query object, and submit it using ZOOM_connection_search().
72 The CQL-to-RPN translation uses a configuration file, the name of
73 which must be specified in the Connection's "cqlfile" option.
75 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
76 function, which takes as its start-term parameter a ZOOM_query object
77 (which may have had either CQL or RPN set into it).
82 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
83 GFS to support this as well. Backend handler, bend_srw_update, does the
84 update work. Code contributed by Ko van der Sloot.
86 Allow retrieval of Search Result-1 information in ZOOM by the use of
87 options that are attached to a result set. ZOOM documentation updated
90 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
91 UTF-8 conversion. Patch by Raj Patel.
93 Added option -m to GFS to control formatting of timestamps in log file.
95 Added 'exit' as synonym for 'quit' in yaz-client
97 Added support for specifying SRW resultSetId + resultSetIdleTime in a
98 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
99 for the new members. Patch by Ko van der Sloot.
101 Added support for SRU POST. It is supported for content-type
102 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
104 Do not build the separate Multi-threaded (MT) library libyazthread.la.
105 Instead make the library libyaz.la multi-threaded. Threading as a whole
106 can still be disabled by configure option --disable-threads. Previosly,
107 with older GLIBCs there were problems with MT libs under Apache. This
108 has now been fixed a long time ago.
110 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
113 CQL module modified to be case insensitive for relations/indexes/operations.
115 Fixed bug in CQL transform code: incorrect value relationModifieder
118 Added 'show all' command for yaz-client which retrieves all results
121 Added new yaz-client, xmles, which takes a (private) OID and
122 a document to be sent as an extended service request.
124 Describe new yaz-client commands wait_response and set_auto_wait.
126 Increase TCP/IP listener backlog from 3 (which I am guessing was
127 copied from the SunOS manual entry way back when) so SOMAXCONN, so
128 that the socket will queue as many incoming connections as it's able
129 to handle ongoing connections. In other words, it will never now
130 refuse a connection that it would be able to handle merely because
131 it's not got around to accepting() enough of the pending connections
132 yet. This is the behaviour anyway under Linux, where the listen()
133 argument is ignored; but not under BSD and on systems such as
134 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
135 YAZ-based servers should now be uniform across operating systems in
138 yaz-marcdump uses 64-bit file access on some systems. This is enabled
139 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
140 This allows yaz-marcdump to read large MARC batches (>2 GB).
142 Modified all YAZ source files - except the source which is auto-generated
143 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
146 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
147 corresponding to the existing *_setl() function. These allow option
148 values containing arbitrary valuues.
150 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
151 ZOOM_resultset_sort() in new applications. Its behaviour is identical
152 except that it returns an indicator of whether or not the sort
153 criterion was accepted (0 for OK, -1 for invalid).
157 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
158 MARC output rather than returning "new" buffer.
160 yaz-client warns about unknown init options.
162 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
166 Added support for SRW sort in Generic Frontend Server. Patch
167 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
168 sortKeys - or NULL if none is provided.
170 Fixed bug #307: It was impossible to specify indefinite/no timeout
171 for ZOOM_event. Special timeout value -1 now means indefinite timeout
174 Added support for multiple languages and charsets to be specified in
175 ZOOM. Each charset/language is separated by a blank. If negotiation is
176 in effect in init-response, Option
177 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
178 Code based on patch by Vasiliy Osadchuk.
180 Fixed bug #306: infinite recursion that occurred when calling
181 yaz_log_level_init as the first call (before other log level or
184 Fixed bug in scan handling in front end server: if preferred-Position-In-
185 Response was non-present, a NULL pointer referece was performed.
189 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
190 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
191 now defined for all those error codes. So instead of putting 109 in
192 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
193 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
195 Modified the yaz-marcdump utility to skip garbage bytes between MARC
198 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
200 Program yaz-client now exits and produces an error message if multiple
201 Z39.50 servers are specified on the command line (none or one allowed
204 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
209 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
211 Fixed bug #272: Preserve spacing for CCL terms.
215 Added support for virtual hosts and multiple backend servers for
216 the YAZ frontend server. The configution is XML based and
217 support specificition of CQL to RPN mappings and explain information.
218 See section "Virtual Hosts" in the YAZ manual.
220 Extended OPAC display utility. OPAC display utility renders
221 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
222 to supplement yaz_marc_decode_wrbuf.
224 Fixed a bug in MARC decoder that could caused it to crash for some
225 invalid MARC records. More diagnostics and warnings where added in
226 XML output (warnings, etc are stored in comments).
228 --- 2.0.34 2005/02/08
230 Fixes for UNIX domain sockets. Bug #261.
232 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
234 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
235 Added yaz_marc_subfield_str which defines subfield lead string which is
236 used in YAZ_MARC_LINE format. Default string is blank+$. Added
237 yaz_marc_endline_str which defines end of fields string used in
238 YAZ_MARC_LINE format. Default string is newline.
240 Experimental support for MarcXChange. This format can be produced
241 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
242 http://www.bs.dk/standards/MarcXchange.xsd
244 Added yaz-client commands scansize that sets maximum number of
245 entries to be returned by scan.
247 --- 2.0.32 2005/01/11
249 Added support for SRW scan in yaz-client and Generic Frontend Server.
251 * Added whereInList member to SRW Scan Term.
253 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
255 Fixed NMEM system to return aligned blocks on the smallest boundaries
256 that are suitably aligned for all possible types on the particular
257 architecture YAZ is being built for.
259 --- 2.0.30 2005/01/04
261 Fixed numerious warnings that was issued with newer versions of GCC.
263 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
264 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
267 Make YAZ Generic Frontend Server slightly faster.
269 Enhance (and reduce) logging for Generic Frontend Server.
271 Revert YAZ log system so that it flushes every write operation
272 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
274 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
275 instead of LOG_, due to name clash with syslog(3). LOG_ are still
276 present. New applications should define YAZ_USE_NEW_LOG=1 - this
277 will effectively disable old definitions.
279 --- 2.0.28 2004/11/09
281 Added yaz_log_time_format which specifies log format using
284 Added yaz_log_module_level which returns mask for a module. Value
285 is non-zero mask a if module is enabled; zero if disabled.
287 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
288 in include/yaz/cql.h.
290 Fixed bug #176: Dont throw diagnostics on empty SRU args.
292 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
294 Fixed bug #172: RPM builds does not enable SSL.
296 Doxyfile.in part of dist. Doxyfile generated by configure.
298 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
299 are given and the corresponding component does not exist.
301 Extend CCL documentation in YAZ reference. Describe r=r.
303 --- 2.0.26 2004/10/01
305 Fixed MARC->MARCXML conversion to properly deal with
306 fields, subfields, indicators having non-ASCII characters.
308 Fixed MARC->MARCXML conversion so that ASCII control characters
309 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
312 Added YAZ GFS support for conversion from Z39.50 surrogate
313 diagnostics to SRW surrogate diagnostics.
315 Bug fix: YAZ GFS did not return schema in explainResponse.
317 --- 2.0.25 2004/09/30
319 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
320 now converts recordSchema to elementSetName as well as schema URI.
322 Fixed bug in COMSTACK that prevented HTTP request packages from being
325 --- 2.0.24 2004/09/29
327 Added CCL facility r=r "range" which is similar to r=o "ordered" but
328 does not require white-space before and after the dash in a range, e.g.
329 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
332 Fixed a few AC_TRY_LINK configure tests that did not operate properly
333 due to new GCC removing "redundant" code.
335 Added yaz-client commands scanpos and scanstep that sets preferred
336 position and step-size for scan.
338 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
340 Added CCL utility ccl_qual_buf which parses one or more CCL
341 spec lines in a buffer.
343 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
344 of name and value - ignoring empty lines and comments.
346 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
348 Added odr_get_element_path which returns current element path for an
349 ODR handle. This utility is useful in error handling or user-defined
352 Added ODR_PRINT utility odr_set_stream which is is a more generic
353 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
354 to a write function and pointer to close function. The close function - if
355 non-NULL - will be called during odr_destroy.
357 Fixed bug in CCL parser where truncation char was not removed from
358 right side when truncation=both was in effect.
360 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
363 --- 2.0.23 2004/08/11
365 Fix buffer overrun in CQL parser when dealing with proximity (%).
367 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
368 to UTF-8/UCS conversion is now only based on codetables.xml.
370 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
372 --- 2.0.22 2004/08/06
374 Add support for more "commit changes" in ZOOM (uses Extended Services).
376 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
379 Yet another small fix for configure of SSL.
381 --- 2.0.21 2004/05/14
383 Fix SSL libs for configure when --with-openssl=DIR is given.
385 --- 2.0.20 2004/05/10
387 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
389 SSL comstack now uses yaz.pem certificate file on server side
390 by default. Certificate filename can be configured by calling
391 comstack function cs_set_ssl_certificate_file before cs_bind is used.
393 Fix bug regarding multiple calls to ZOOM_connection_connect.
395 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
397 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
398 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
400 ZOOM now allows inspection of X509 peer certificate for verification.
401 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
403 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
404 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
405 as "modular" but it simplifies things.
407 Added cs_get_peer_certificate to that returns peer X509 PEM.
409 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
410 NULL if SSL is unavailable.
412 Documentation about MARC decoding tools.
414 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
416 --- 2.0.19 2004/03/30
418 Rename CHANGELOG to NEWS to follow GNU style packing.
420 Fix bug with missing initialization of member in init_diagnostics.
421 This bug affects threaded version of GFS server.
423 --- 2.0.18 2004/03/20
425 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
428 Ensure zlib.dll is packed with Windows install.
430 --- 2.0.17 2004/03/17
432 Fix encoding of xsd:string to use text instead of CDATA.
434 Fix endless loop in CQL parser with unbalanced ".
436 Use a more compact way to store MARC-8 conversion tables.
438 --- 2.0.16 2004/03/16 Debian only
440 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
443 Update CQL parser to use new CQL 1.1 modifiers for booleans and
448 --- 2.0.15 2004/03/01
450 Another fix for decoding of XML packed records.
452 --- 2.0.14 2004/02/25
454 Fixes for Chunked encoding. White space not ignored after length spec.
456 Update NS and use default NS for SRW diagnostic elements.
458 --- 2.0.13 2004/02/23
460 Implement ZOOM_resultset_cache_reset which resets record cache.
462 Implement ZOOM_resultset_sort which sorts a result set.
464 Implement chunked HTTP transfer.
466 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
468 --- 2.0.12 2004/02/16
470 Added member 'schema' to bend_explain_rr structure so that backend
471 can specify explain record identifier. Defaults to Zeerex 2.0.
473 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
475 --- 2.0.11 2004/02/16
477 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
480 Added init command for yaz-client which sends "extra" init request.
482 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
483 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
485 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
487 Make ZOOM error code for "invalid query".
489 Fixed compilation for SSL which wasn't properly enabled for all platforms.
491 --- 2.0.10 2004/02/05
493 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
496 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
498 Added option -p <file> to make Generic Frontend Server to write PID file.
500 Added option -D to put Generic Frontend Server in background on its own.
502 Make ZOOM C recognize option "password". If unset, "pass" is used
503 (for backwards compatibility).
505 Fixed a bug in Generic Frontend Server that could make it crash if a
506 client sets characterSetNegotation bit, but didn't pass negotiation stuff
509 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
510 Must be issued before open, in order to be in effect.
512 --- 2.0.9-6 2004/01/12 Debian/Windows
514 Make the SRU server more picky WRT unknown params, etc.
516 Bug fix: ZOOM scan response didn't return displayTerm - when present.
518 New YAZ client command, options, that sets Z39.50 options.
520 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
521 options from a string of tokens (one token for each option bit).
523 Update SRW diagnostic code messages.
525 --- 2.0.9-5 2004/01/07 Debian/Windows
527 Handle user defined stylesheet for SRW/SRU.
529 --- 2.0.9-4 2004/01/06 Debian/Windows
531 Fix bug in decoding of Content-Length.
533 --- 2.0.9-3 2004/01/06 Debian/Windows
535 Fix a bug with decoding of XML packed records.
537 --- 2.0.9-2 2004/01/05 Debian only
539 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
541 Fix bug in SRW/SRU diagnostics decoding.
545 Fixed bug in Generic Frontend Server which could drop records exceeding
546 preferred message size. Reported and fixed by Irina Dijour.
548 Fixed calculation of package size for structured records in Generic
549 Frontend Server. Reported and fixed by Irina Dijour.
551 Fixed namespace for SRW/SRU diagnostics.
553 Fixed SEGV in yaz-client that occured for HTTP connection errors.
557 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
558 this version is incompatible with version 1.0 and older YAZ SRW/SRU
561 CQL changes to reflect recent changes to the specification:
562 * Documentation talks about context sets instead of index sets.
563 * Documentation talks about indexes instead of qualifiers.
564 * The CQL-to-PQF transformer's configuration file now uses
565 "index.set.name = <attributes>" instead of the old form
566 "qualifier.set.name = <attributes>". (Both forms are still
567 understood but the latter is deprecated.)
568 * CQL terms with no explicit index specified are now interpreted as
569 cql.serverChoice instead of srw.serverChoice (which of course
570 behaves exactly the same.)
574 MARC conversion can now generate ISO2709 output in another
575 character set. yaz-marcdump uses this facility if you invoke it
578 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
579 functions from there can be used from C++.
583 Frontend server now transfers memory from decoded packages to stream
586 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
587 references to show up.
589 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
590 the ZOOM Abstract API. The older names for the same options are still
591 also supported for the benefit of old applications.
593 ZOOM-C supports "implementationId" and "implementationVersion" options
594 to go along with "implementationName". These allow the user code to
595 specify identification strings to be sent to servers.
596 Add OID for the new ExtLite attribute set.
598 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
599 as requested/supplid by Ere Maijala <ere@atp.fi>
601 For generic frontend server, reverse the order of
602 "toolkit-supplied / application-supplied" strings sent as implementationId,
603 Name and Version. Also, remove the spaces around the slash. This brings
604 the GFS in line with the behaviour of ZOOM-C on the client side.
606 Add function ZOOM_scanset_display_term.
608 yaz-client shows scan displayTerm if present.
610 Utility yaz-iconv is now installed by default along with the man page
613 Extend configure check for OpenSSL to use pkg-config where available (such
616 Incorporate patch by Morten Bogeskov which allows a Unix file socket
617 server to specify uid/gid/mask for socket using the format
618 unix:[user=uid,][group=gid,][umask=mask,]file=path
619 If file= is omitted the existing format is assumed, e.g.
621 in which case the mask is 0666 (rw for everybody).
623 Major restructure of YAZ source. All source in libyaz is in src directory.
624 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
625 util (utility programs such as ASN.1 compiler, yaz-marcdump).
627 Added man page for utility yaz-marcdump (used to be called marcdump).
628 yaz-marcdump is installed by 'make install'.
630 Fixed a memory leak in Generic Frontend Server that occurred when decoding
631 of incoming package failed.
633 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
635 Change prototype of odr_perror: add const to message string.
637 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
639 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
640 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
641 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
642 DNS lookup. There should not be any compatibility problems with this
643 assuming that blocking=1 or 0 is used.
645 Fix bad reference in UNIX comstack in function cs_addrstr.
647 Fix for compilation on AIX.
649 The generic front-end server (server/seshigh.c) now supports returning
650 Init diagnostics to the client in User-information-field, in
651 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
656 Allow any CQL relation (not just all,any,exact,scr).
658 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
659 that features the same UI.
661 Implemented command update0 in YAZ client which is equivalent to
662 update but uses old of Ext Update ASN.1.
664 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
665 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
666 Previously no OID was used for this info.
668 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
669 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
670 returns 'malformed search term' otherwise.
672 SortResponse member resultCount now set to NULL in sort handler of
675 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
678 Add three new utility functions for translating OIDs between various
679 formats -- symbolic name such as "Usmarc", minus-1-terminated int
680 arrays and dotted strings such as "1.2.840.10003.9.5.1":
681 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
682 char *oid_to_dotstring(const int *oid, char *oidbuf);
683 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
685 Reverted modifications for ES Update definition for z_IU0Update
686 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
687 is back to YAZ 2.0.2.
689 String value attributes for CCL parser.
691 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
692 which their FirstSearch server returns in Init responses, sometimes
693 carrying useful diagnostic information when Init fails. This has the
694 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
695 "z39.50/oclcui.asn", where its definition is somewhat different from
696 what OCLC document on their web-site, as required to interoperate with
699 Support for anonymous authentication in yaz-client. Use the command
702 * Fix the OID of the Index Data-local "admin" Extended Service from
703 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
704 the 1000, which indicates a locally-defined OID, was a mistake.
708 Fix CCL directive @case handling so that it affects string match for
709 both CCL keywords and qualifiers.
711 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
712 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
713 Decoder has been updated with ASN.1 changes as listed in
714 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
715 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
716 z_IUUpdate, remains unchanged.
718 ZOOM_record_get may now return a record in a specific character set.
719 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
720 "from" is the character set of record as returned by target. "to" is
721 the character set to be returned. If omitted, "to" is UTF-8.
723 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
725 New ODR utility, odr_getelement, which returns name of element for
726 which encoding/decoding failed.
728 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
729 in cases where a required element was omitted.
731 Bug fix: some MARC8 sequences were not converted.
733 New ZOOM option "step" which specifies number of records to be
734 retrieved in one chunk. Used in conjunction with "start" and "count".
736 SRW support for yaz-client. Use scheme http: to use it, e.g.
739 yaz-client no longer does (un)intelligent character set conversions
740 by default. Can be enabled with charset and marc_charset commands.
742 xmalloc trace fix for 64-bit systems such as DEC alpha.
744 Solaris 2.6 compile fix.
746 New function, cql_strerror() translates SRW error codes, as returned
747 by cql_transform_error(), into human-readable English strings. Used
748 in yaz-client diagnostics when appropriate.
750 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
751 converts it into a type-1 query which is sent to the server. This
752 makes CQL available for use with all Z-servers, as opposed to the tiny
753 minority that can handle CQL queries themselves.
757 New Debian package layout similar to the Redhat Package layout.
759 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
760 and search result respectively.
764 Redhat package is now several packages: libyaz (runtime libraries),
765 libyaz-devel (development and documentation, and yaz (utility programs).
766 Package spec file by Morten Bøgeskov.
768 New member 'schema' in struct bend_fetch_rr which the name of requested
769 schema (SRW/SRU) for record (or NULL if none was given). The fetch
770 handler MAY set this to reflect the schema of the returned record.
772 New member 'display_term' in struct scan_entry. GFS now sets member entries
773 and allocates scan entries to be filled by user scan handler. In previous
774 version, entries member was allocated by the scan handler. That still works,
775 but the GFS will ignore member display_term - assuming it was NOT set by
776 the handler. The fact that the GFS now allocates the entries both allows
777 for new members and makes a scan handler easier to write.
779 Fix CQL lex buffer overflow.
781 SRW/SRU recordPacking. For SRW default recordPacking is string. For
782 SRU default recordPacking is string.
784 SRU protocol support for frontend server.
786 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
788 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
790 Added scan for the ZOOM shell (zoomsh).
794 * String Identifers for Schemas (Amendment 5).
795 http://lcweb.loc.gov/z3950/agency/amend/am5.html
796 Old definition for schema
797 Odr_oid *schema; /* OPT */
802 Z_InternationalString *uri;
803 #define Z_Schema_oid 1
804 #define Z_Schema_uri 2
807 * resultCount parameter to Sort Response (Amendment 1).
808 http://lcweb.loc.gov/z3950/agency/amend/am1.html
810 Support for SRW 1.0 over HTTP. This is an optional feature and
811 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
814 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
815 on the same port. SRW SearchRetrieveRequests are mapped
816 to bend_init,bend_search,bend_fetch,bend_close.
818 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
820 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
821 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
823 ZOOM connections are SRW based if schem http is used for hostname
824 in connect, e.g. z = ZOOM_connection_new("http://myserver");
825 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
827 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
828 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
829 distance=n, order=true/false, relation=le, prox unit=word. If
830 n is omitted, distance 1 is used.
832 Fixed problem with C compiler include path in wrong order.
834 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
835 on Solaris. Patch from Ko van der Sloot.
837 New MARC decode API. All new functions operate on a yaz_marc_t
838 handle. The most important new functions are: yaz_marc_create,
839 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
840 decode and destroy respectively. Decoder can produce formats
841 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
842 include/yaz/marcdisp.h.
844 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
845 to UTF-8, UCS-32, wchar_t or Latin-1.
847 * Prototypes for yaz_iconv_-functions moved to separate header
848 include/yaz/yaz-iconv.h.
850 Make a few private functions 'static' in unix.c. This prevents
851 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
853 For ZOOM connection, the options targetImplementation{Id,Name,Version}
854 are set when Init Response is received.
856 New function ZOOM_connection_error_x similar to ZOOM_connection_error
857 but returns diagnostic set as well.
859 New function yaz_strerror which is a portable wrapper for
860 strerror/strerror_r/GetLastMessage.
862 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
863 is returned for MARC. If type is "oai", then OAI MARC is returned.
865 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
870 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
872 Fix bad race conditions on SIGTERM and terminate gracefully in
875 Move retrieval (data1) module to Zebra since nobody seems to be
878 Add GRS-1 render for ZOOM using same format as yaz-client.
882 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
884 Fix broken ESpec handling in data1 module.
886 SGML reader parses comments and makes them part of the data1 tree.
888 Added several type casts so that YAZ compiles as C++ code.
890 ZOOM didn't handle PDU encoding failures properly.
892 Added more Bib-1 diagnostics (approved extensions).
894 GNU configure: better check for iconv.
896 More portable use of accept, getpeername. Check for socklen_t. Use
897 int/size_t if socklen_t is not defined.
901 PQF parser rejects bad queries - including those with extra
902 characters in them. PQF parser used to silently ignore that.
903 Cleaner API for PQF added, which allows you to get detailed
904 error information for bad queries (see yaz/pquery.h).
906 Fixed bug in ZOOM_record_get for type "database".
908 Implemented mini iconv library supporting conversions between
909 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
911 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
915 Fixed ZOOM C record cache so that preferredRecordSyntax and
916 elementSetName is used to check for already fetched records.
920 Added three members in bend_initrequest structure to facilitate
921 character set negotiation.
923 Fixed a bug in frontend server that could cause indefinite
924 loops under rare conditions.
926 Revised character set utilities (charneg.h) so that encoding
927 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
929 For PQF, directive @term <type> sets term type for Scan/Search.
930 Here <type> is general, string, numeric, null. The term type
931 is inherited - just like @attr.
933 New call odr_set_charset that sets character set conversion for
934 international-strings on a ODR stream. Prototype is:
935 int odr_set_charset(ODR o, const char *to, const char *from);
936 The InternationalString is still represented as C string in YAZ
937 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
938 won't). On the protocol level, you can use any encoding.
940 Support for UNIX sockets in ZOOM.
942 Solaris recv sometimes returns errno == ENOENT. It is treated as
943 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
945 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
946 both client and server. Code by Morten Bøgeskov.
950 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
951 that they can be used directly from Visual Basic. You must recompile
952 your windows APP if you're using ZOOM.
954 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
955 Commands "lang" and "charset" sets language and character set respectively.
956 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
957 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
959 Attributes from multiple CCL fields may be OR'ed rather than merged
960 using directive "@field or". Fields are still merged by default -
961 equivalent to "@field merge".
963 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
966 Fixed bug in zget for parameter ExtendedServicesResponse.
972 Added PQF feature: '@attr type=value' may be written as '@type=value'.
974 Client displays USR.1:SearchResult-1 (hits per term).
976 Additional Search Info for search in Generic Frontend Server.
978 Fixed CCL parsing of "field=s".
980 WIN32 installer - using the excellent NSIS software from nullsoft.
982 Fixed CCL parsing of "field = - <number>".
984 Added function yaz_marc_decode that decodes MARC for line mode
985 display or XML (similar to that used by JZKit).
987 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
988 Z39.50. But ISO/ILL was, however.
990 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
991 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
993 http://lcweb.loc.gov/z3950/agency/amend/am2.html
994 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
998 New YAZ client features: Command completion and new commands:
999 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1000 Code provided by Jacob Poulsen.
1002 New call oid_trav, that visits all registered OIDs via callback.
1004 Function ZOOM_record_get now returns const char pointer rather than
1005 void pointer. It saves a lot of type casts.
1007 For YAZ client, command "auth" now allows you to set authentication
1008 in IdPass style. It is enabled when three tokens are given - order
1009 is user, group and password.
1011 Fix memory leaks in MARC record handling for ZOOM.
1013 New option for YAZ client, -k <kilobytes> that sets
1014 maximum record size. Similar to -k option for generic frontend
1015 server and yaz-ztest.
1017 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1019 Prefix query parser reports "fail" when bad attribute set is given.
1021 Fix in MARC decoder. Proximity logging. Fix for attribute set
1022 in scan handler for server. Patches by Shigeru Ishida.
1024 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1027 Configure option --with-openssl=<dir> now works when a directory is
1028 specified. Patch provided by Morten Bøgeskov.
1030 New option for YAZ client, -u <auth>, that sets authentication.
1032 ZOOM fix: error information was sometimes "missing", since error
1033 was cleared/reset too when it shouldn't.
1035 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1037 --- 1.8.4 2002/01/04
1039 Scan for ZOOM API. New object ZOOM_scanset. New functions
1040 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1041 ZOOM_scanset_destroy.
1043 New ZOOM function, ZOOM_connection_last_event, that returns type
1044 of last event (such as "receive data", "send data", "apdu received",
1047 New ZOOM option, schema, that specifies schema for retrieval.
1049 New CCL feature. Qualifiers can be aliases for one or more
1050 other qualifiers (if more than one is given, OR is used).
1052 ZOOM uses named result sets if target supports it.
1054 Two new YAZ client commands: . (dot, which sources a script of YAZ
1055 client commands), and ! (to execute shell command.). Implemented
1058 Working on Debian packages.
1060 --- 1.8.3 2001/11/19
1062 YAZ client enables named result sets only if target supports it.
1064 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1066 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1067 with key="host" to get same result.
1069 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1070 Function Z3950_resultset_record(s) returns references to records
1071 "owned" by resultset. To become owner use Z3950_record_clone.
1073 Function z_ext_record handles Extended Services. Thanks to
1076 --- 1.8.2 2001/11/12
1078 CCL Parser fix: ignore token comma when dealing with and-lists.
1080 Documentation updates for COMSTACK.
1082 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1083 Changed prototype Z3950_records. For some functions, int parameters
1084 were changed to size_t.
1086 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1089 New MARC decode/display function, marc_display_exl, which properly rejects
1090 non-ISO2709 records. YAZ client uses it.
1092 --- 1.8.1 2001/10/29
1094 Fix bug: local attribute set wasn't set correctly in PQF strings.
1098 * Old Z39.50 codecs no longer supported.
1100 Added ZOOM C binding. See http://zoom.z3950.org/
1102 Renamed states for COMSTACKs to avoid confusion with events.
1104 Implemented cs_look and proper cs_rcvconnect.
1106 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1108 Configure detects POSIX threads on OpenBSD.
1110 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1111 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1113 When error is returned from present handler, non-surrogate diagnostic
1114 is returned in present response (and fetch handler is no longer called).
1116 * Minor adjustments to pquery parser (PQF). Token characters may be
1117 escaped by using backslash (C-style).
1119 PQF parser allows string attribute values to be specified. For @attr,
1120 non-numeric characters after the equal-sign are treated as strings
1121 (e.g. @attr 9=title).
1123 CCL trunction character may be defined (@truncation in file)
1125 * function zget_ExtendedServicesRequest sets waitAction to
1126 waitIfPossible (was wait).
1128 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1131 CCL operator names may be set in field definition files (CCL_bibset).
1132 See ccl/bib1 for an example.
1134 Fixes in ASN.1 compiler for C++ compatibility.
1136 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1137 and "op_or" to avoid conflict with C++.
1139 Fixed problem with GNU readline detection on Redhat 7.0.
1141 Added step-size for Scan backend handler.
1143 Fixed bug that made the frontend server crash when no attribute
1144 set was specified for scan.
1146 Front-end server automatically switches to original working directory
1147 when installed as an NT service. Previously -w had to be specified to
1150 Added extended attributes for retrieval module (data1), so that data1
1151 records carry d1_readXML/SGML attributes. d1_read also supports
1152 null-data rules ( <tag/>)
1154 On UNIX when POSIX threads are available, a separate library libyazthread
1155 is created. Programmers should link with that library and the yaz library
1156 when using threads. The reason for the split was that some applications
1157 on Linux, such as Apache, doesn't work well when using shared objects that
1160 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1161 (or any frontend server) in SSL mode by specifying ssl: followed by
1162 address. Only tested on UNIX.
1164 Added feature for CCL module. Virtual structure s=al or s=ol generates
1165 and-list and or-list respectively instead of phrase search.
1169 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1170 log_mask_str. This was done to avoid name conflicts with other libraries
1171 (such as other PHP extensions).
1173 Added raw OID member for preferred record syntax (request_format_raw)
1174 and returned record syntax (output_format_raw) for backend fetch method.
1176 Config file yaz-config now accepts options so that it returns specific
1177 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1179 Shared library support for UNIX using GNU libtool.
1181 * Modified backend interface. Request/Response struct's replaced by
1182 one read/write C struct. For example bend_fetchrequest and
1183 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1184 Every handler - even search has to be registered in bend_init
1185 handler. This means that the YAZ library no longer refers to
1186 external functions and it makes it possible to make the whole
1187 thing a single DLL/SO.
1189 Added Segment handler for backend server.
1191 Added Zmbol/Zebra administrative functions to YAZ client.
1193 Threaded frontend server on UNIX (when POSIX Threads are available).
1194 Starting the server with option -T enables multi-threading.
1198 Added configure option --enable-comp/disable-comp to control use
1199 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1200 located in sub directory asn.
1202 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1203 in ${exec_prefix}/bin along with the other programs yaz-client and
1206 GNU automake used to maintain makefiles.
1208 Added several OID's.
1210 Changed retrieval module so that we can load records with no abstract
1211 syntax defined. Tagpaths in these records are fully composed of string
1214 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1218 On UNIX, the generated makefile now supports a proper 'make install'.
1219 The prefix can be set via GNU configure to set the install location
1220 (default is /usr/local).
1222 * YAZ programs client and ztest were renamed to yaz-client and
1223 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1224 locations, such as /usr/bin,/usr/local/bin,etc.
1226 * YAZ Header files were moved from include to include/yaz. YAZ Header
1227 files are referred to as include <yaz/log.h> rather than <log.h>.
1228 The YAZ include path (-I ..) is therefore the same as before. Programmers
1229 should update their #include statements or use -Ipath/include/yaz
1230 instead. The main motivation for doing this change is that YAZ header files
1231 can be installed in "standard" locations /usr/include,/usr/local/include
1232 without introducing conflicts, since ALL YAZ header files are stored
1233 in subdirectory yaz (under /usr/include for example).
1235 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1236 rather than project/workspace files. We switched because project files
1237 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1240 Changed name of logging function, logf, to yaz_log, to prevent name
1241 clash with some math-log functions. The YAZ header log.h defines logf
1242 to yaz_log (#define) so there should be no incompatibilities by this
1245 Added bend_start/bend_stop handlers for server. These handler are
1246 called on start/stop of server. For windows they are called whenever
1247 a service is started/stopped.
1249 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1250 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1251 in util/yc.tcl. The auto-generated C code structures are, in a few
1252 cases, incompatible with the old decoders. There are differences in the
1253 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1254 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1255 The preprocessor variable ASN_COMPILED is defined when the compiled
1256 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1257 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1258 wish to use the old encoders/decoders you can specify --disable-yc
1261 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1262 version so that it supports both new - and old version of DB Update
1264 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1265 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1266 change. The name parameter can be set to 0 in which no name is specified
1267 for the construction. The macros odr_implicit and odr_explicit sets name
1268 parameter to zero for the construction involved. New macros
1269 odr_implicit_tag and odr_explicit_tag are similar to the others,
1270 except that a name parameter is added. For programmers' that don't use
1271 ODR they probably only need to change the call to z_APDU and z_External.
1273 Added access control facility by interfacing the TCP wrapper library.
1274 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1275 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1276 name of the daemon and enables the access control as specified in
1277 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1279 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1280 den Dool <H.M.vdnDool@kub.nl>.
1282 Added reference ID parameter to most functions in server API - refer
1283 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1285 Changed name of ccl library to libccl.a (was ccl.a).
1287 Fixed bug in decoder for Explain (Category TargetInfo).
1289 Added support for GNU readline in client. Thanks to Jacob Poulsen
1290 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1292 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1293 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1294 IMPLEMENTATION! This change was made to the development version before
1295 the ZIG decided to retract the amendment. If any users MUST be
1296 compatible with the original Update definition, PLEASE CONTACT US, and
1297 we will include a separate definition corresponding to the old Update
1298 ES. Note that because of the change to the ASN.1 of the
1299 TaskPackageRecordStructure we cannot define a single structure that
1300 will support both versions.
1302 * Added const modifier to buffer parameter for some ODR/BER encoding
1303 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1304 completeWAIS, odr_dumpBER.
1306 Fixed bug in client.c which caused a crash when a scanResponse didn't
1307 contain positionOfTerm.
1309 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1310 * will cause an error in a client if a non-YAZ target sends both a
1311 * list of Scan entries and non-surrogate diagnostics.
1313 Retrieval module enhancements. Tag sets may be typed in the reference
1314 to it. From the .abs-file the "tagset" directive takes a third optional
1315 integer type for the tag set referenced. From a .tag-file the "include"
1316 directive takes a third optional type as well. The old "type" directive
1317 in the tag set itself is still recognized but acts as the default type
1320 Backend interface change. Individual Scan terms returned from bend_scan
1321 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1322 in include/backend.h.
1324 Retrieval module enhancements. Multiple tag sets and attribute sets may
1325 be specified in abstract syntax specs. Revised the error/warning for
1326 logging messages reported by the retrieval module when reading the
1329 Object Identifier system (oid_..) changed. The API is backwards
1330 compatible but the oid-routines now allocates new OID's when needed.
1331 Raw OID's may be specified in oid_getvalbyname.
1333 YAZ now uses GNU configure to generate Makefile(s).
1335 * Minor changes in some of the member names of DeleteResultSetRequest and
1336 DeleteResultSetResponse. See include/proto.h.
1338 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1339 and added member 'languages' in TargetInfo (which was missing).
1341 Changed the way attribute sets are handled in the retrieval
1342 module. These are now cached, just like the abstract syntaxes
1345 Changed YAZ so that it links with compiled ASN.1.
1347 Added Explain-schema definitions and mapping routines. The following
1348 Explain categories have been implemented: AttributeDetails,
1349 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1351 Fixed minor bug in Windows version of Server Library.
1353 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1355 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1357 Added EXTERNAL: UNIverse Resource Report (non-standard).
1359 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1360 ENUMERATED and SET OF.
1362 * Added 'const' to some of the char pointer arguments for the
1363 functions, data1_read_node, data1_getelementbytagname,
1364 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1367 Fixed bug in data1_insert_taggeddata - the last_child member of
1368 parent wasn't initialised.
1370 * Changed data1_read_record and data1_read_node so that the supplied
1371 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1372 doesn't refer to any parts of the "SGML"-buffer.
1374 Fixed bug in server library (Windows version of statserv_remove).
1376 * Changed code so that it compiles as C++. The type definition
1377 of Odr_fun which is a member of Odr_arm was changed. The result is,
1378 that an explicit typecast is needed for the fun pointer when
1379 using Odr_arm - as in:
1380 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1382 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1384 Implemented the new structured date and time definition as approved
1385 by the ZIG. Added schemaId element to the specificTag in Espec-1
1386 (also approved at the last ZIG). Thanks to RVDM.
1388 Added some Object identifiers (RVDM).
1390 Changed the Update Extended Service (RVDM).
1392 Added command "refid" to client which specifies referenceId for
1393 the following requests.
1395 Implemented extended service handling for server. See ztest.c
1396 for an example as well as backend.h. New handlers are registerd
1397 in the Init handler.
1399 * Changed interface for sort in server.
1401 Added new members to statserv_options_block. It allows a server
1402 to read options from another source than just the command line. Thanks
1403 to Charles Woodfield.
1405 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1406 renamed to zboolean. Some C++ compilers complained about the name.
1408 Minor changes to gils.abs. Added index 's' (sort) on title
1409 and date/time-last-modified.
1411 --- 1.4pl2 1998/1/30
1413 Fixed bug in server library regarding inetd mode (-i). This bug
1414 was introduced by release 1.4.
1416 --- 1.4pl1 1998/1/29
1418 Added sort facility in client and backend server interface.
1420 Fixed problem with dependencies in Makefile(s).
1422 Fixed bugs for encoders/decoders of extended services and
1425 Implemented sub-tree feature for schemas. Sub-trees are
1426 referenced in *.abs-files. See explain.abs for an example
1427 of the use of this feature.
1429 Modified bib1.att; local attributes for ANY didn't include
1430 ANY itself (only affects use of the retrieval module).
1432 Fixed bug in plain SGML reader in function data1_read_node:
1433 tags with prefix "var" was incorrectly interpreted as variants.
1435 Added feature "sub-schemas" to enable references to - and definitions
1436 of - group of elements.
1438 * Removed member parent from type data1_element (in data1.h).
1440 Implemented function odr_nullval() that returns the value of
1443 * Removed member num_children from data1_node (in data1.h).
1445 Made NT service interface part of the server library. The
1446 function statserv_main uses the NT service when required and
1447 calls the statserv_start / statserv_close routines.
1449 Routine zget_SearchRequest and zget_PresentRequest fills
1450 resultSetName/Id member with "default" instead of "Default".
1452 Fixed memory leak in server. Request queue member wasn't freed.
1454 Fixed nmem_exit so that memory is freed.
1458 Revised the CCL parser utility to be thread safe.
1460 Added function, oid_ent_to_oid, to replace the function
1461 oid_getoidbyent, which is not thread safe.
1463 * Added nmem_init and nmem_exit to initialize and release
1464 NMEM resources. Function nmem_init should be called once in the
1465 initial thread before NMEM/ODR is used. statserv.c and client.c
1466 have been changed accordingly. The change was necessary to make
1467 NMEM thread safe. The NMEM memory pool is shared amongst threads
1468 in a process. Unix-based applications will still work fine without
1471 Added NT Services interface for the the Z39.50 (statserv) Server.
1472 Refer to the ztest.c source on the usage.
1474 Windows 95/NT port using MSVC5.0. Project files are included in the
1477 * Defined new 'global' handle for the retrieval (data1) system. The
1478 new handled, data1_handle, describes the state of the data1 system.
1479 This handle is passed as first argument to virtually all
1480 data1 related routines. The functions data1_create and data1_destroy
1481 creates and destroys a data1 handle respectively.
1483 Added ODR encode stream member to all backend request structures
1484 init, search, scan etc. This stream should be used to allocate all
1485 memory used for the response when thread safe operation is needed.
1487 Changed the comstack utility, cs_addstr, to be thread safe. The
1488 returned hostname string returned by the function is now part the
1491 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1492 function. The cs_straddr takes a COMSTACK handle as argument, so this
1493 function must be used after cs_create and before bind/connect.
1494 This function is thread safe.
1496 Moved test server to 'ztest' directory - generic server code still
1497 in 'server' directory.
1499 Made prefix query (pquery.c) utility thread safe.
1501 Added new function modifier YAZ_EXPORT to 'export' public DLL
1502 functions when using windows (see include/yconfig.h).
1504 Added definitions to the OID database (util/oid.c) (RVDM).
1506 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1508 Added call to ccl_rpn_delete in client program.
1510 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1511 release of RPN structure.
1513 Added support for C++, headers uses extern "C" for public definitions.
1514 With input from RVDM.
1516 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1517 Thanks to Ronald van der Meer (RVDM).
1519 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1521 Added support for private extensions to the OID database
1522 (oid_setprivateoids()). Thanks to RVDM.
1524 Added optional, physical ANY (key replication)
1526 Fixed null-reference problem in GRS-1 output filter.
1528 Proximity operator added to Prefix Query Format (PQF).
1530 In test client command "base" accepts multiple databases.
1532 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1536 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1538 Smallish bug-fixes in the new encoders/decoders (explain).
1540 Bug fixed in DeleteRequest.
1542 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1544 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1546 Added SOIF syntax (using private OID for now) to retrieval module and client.
1548 Added Update extended service.
1550 Added SearchResult-1 additional info structure.
1552 Added optional CCL (ISO8777) interpreter as separate module. Available
1555 --- 1.2 1996/6/10 (1st anniversary release)
1557 Added Summary record syntax. Lightly tested.
1559 Added OPAC record syntax. Untested.
1561 Added ResourceReport service encoders/decoders. Untested.
1563 Fixed bug in z_Unit - wrong tagging on unitSystem.
1565 Fixed bug in the DiagRecs decoder.
1567 Added options for max PDU size and session timeout to frontend-server.
1569 Added documentation of query-language parsers and other supporting utilities.
1571 [frontend-server] Added Attribute set to the bend_scanrequest API.
1573 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1574 surrogate diagnostics were generated.
1576 [retrieval] Allow multiple local values for attribute.
1578 [retrieval] Allow multiple attributes per element in .abs files. index type.
1580 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1582 --- 1.1pl2 1996/4/10
1584 Minor changes, mostly specific to Zebra's requirements (retrieval)
1588 Repaired bug in frontend server when running multiple listening
1589 endpoints in dynamic mode.
1591 z_External() now won't break if a known, ASN.1 value comes encapsulated
1592 in an octet-string. The value will pass through unmodified in an Odr_oct.
1594 Added a bit of code to the demo client to decode & display
1595 ASN.1-structured records represented in the octet-aligned branch of
1596 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1598 Added z_ext_getentbyref() to the ASN module. Doc updated.
1600 * Completed the SCAN definition in the ASN module. This may break SCAN
1601 code based on older YAZ-versions at compile-time. The fix is easy -
1604 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1605 under the SCAN definition. Remember to initialize this, server-people.
1607 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1608 that this does not extend to ODR and ASN.
1610 Comstack allows insertion of established socket (primarily for
1611 inetd-operation of servers). Doc updated.
1613 Front-end server can now start from the inetd in TCP mode. Doc
1616 --- 1.0pl4 1996/1/24
1620 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1621 the rank and record number.
1623 Adjustments to the frontend server.
1625 Fixed diagnostic BER dumper. It ignored the file argument.
1629 Various changes to retrieval module.
1631 Changed the union discriminators of the protocol files from enums to
1632 ints paired with #defines.
1634 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1637 *Changed operator in the RPN structure to 'roperator', again to avoid a
1640 Fixed problems in Explain decoders/encoders.
1642 --- 1.0pl2 1995/12/6
1644 Memory bug in log module fixed.
1646 --- 1.0pl1 1995/12/5
1648 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1650 Bug in Explain DatabaseInfo module fixed.
1652 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1656 The shift to v1.0 signals that we now consider the *core* functionality
1657 of YAZ reasonably stable (the core being more or less equivalent to
1658 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1659 tested (Explain not at all - though that will happen soonish).
1661 Minor changes to code to support Windows port.
1663 Various minor changes after we're getting to use GRS-1 & co. more.
1665 Added Espec-1 format.
1667 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1668 of the protocol and it cannot be selected when encoding (maps into 'string'
1669 when decoding). Needed to talk to some servers.
1671 Demo client can request simple element set names.
1673 Added Diagnostic Format encoders/decoders.
1675 Added simple Close handling to frontend server (no hooks for resource
1676 reporting yet), and demonstration client.
1678 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1680 --- 1.0b3 1995/08/24
1682 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1683 handled incorrectly when records were requested in the searchResponse. This
1684 will only affect you if you use the frontend-server.
1686 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1687 Test-client will ask for and print GRS1. Ztest will return dummy records
1690 Added Explain encoders/decoders to the service-level API. Untested.
1692 Added Extended Services: Item Order encoders and decoders to the Service-
1693 level API. Untested. We could use a recent copy of the pertinent bits
1694 of the ILL protocol to add those bits.
1696 Added diagnostic format 1 encoders/decoders to the service-level API.
1699 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1700 odr_cons.c, which causes a more correct output.
1702 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1703 was always set to 0 when no records were requested in the searchRequest.
1705 * Added better external-handling. This shouldn't harm old code that
1706 *encodes* externals. It can break code that looks for a
1707 'single-ASN1-type' representation, since those types that are known
1708 are now decoded immediately. Look at the SUTRS sample code in
1709 seshigh.c and client.c. Documentation updated.
1711 Handling of structured records in bend_fetchresponse. Length -1 marks
1712 structured record, type is deduced from format field.
1714 --- 1.0b2 1995/06/27
1715 Fairly quick maintenance release to add SUTRS support.
1717 Fixed handling of SUTRS records in the demonstration client.
1719 * Added format field to the bend_fetchrequest and bend_fetchresponce
1720 structures of the backend API (frontend server). When the record is
1721 returned, the value of the format field is mapped to an OID. The
1722 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1723 of the record. The special value VAL_NONE in the bend_request means
1724 that no specific format was requested by the client. Documentation
1725 updated accordingly. Test server (ztest) will return a fixed dummy
1726 SUTRS record if your client requests SUTRS.
1728 Documentation updated accordingly.
1730 You can now set external libraries and RANLIB support in the top-level
1734 First public release.
