3 Translation of proximity nodes from CQL into PQF now works.
5 Moved to automake 1.8, 1.9.
7 Added function yaz_log_set_handler which allows a log handler
8 to be installed. This handler will be called for all log messages.
9 Output to file is also produced; but that can be disabled by passing
10 NULL fname to yaz_log_init_file.
12 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
14 For SRW (including GFS), accept application/soap+xml as content-type
17 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
18 produces NO stylesheet reference even if a default stylesheet is specified
23 Updated Windows package to include yazd.dll + yazd.lib for the
24 Development component.
26 If the environment variable YAZ_LOG is set, then it is used as a
27 string indicating the default level of logging to use if not
28 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
29 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
30 used as before. So, for example, to omit warnings from YAZ logging,
33 cql_transform() now map structure and other attributes before indexes,
34 so that index-specific structures and other attributes can override
35 defaults. So now a combination of mapping specifications such as:
37 index.dc.date = 1=date-modified 4=5
40 cql_transform() now also respects the "always" mapping specification,
41 which establishes an initial set of attributes to be used for all
42 terms except where overridden by more specific attributes associated
43 with the index, relation or modifier.
45 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
46 which mode to use; one of "post", "get" or "soap" (SRW, default).
48 Fixes for yaz_iconv routines: changed trie-based character set conversions
49 to use only non-negative values for bit fields due to Sun's C compiler not
50 supporting negative values.
52 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
53 sequences where not read correctly. Fix by Rustam Usmanov.
55 Updated win/makefile to use options, settings which makes things
56 compile with VS C 2005.
60 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
62 In ZOOM socket code, use select instead of poll on MacOSX.
64 ZOOM-C now support client-side compilation of CQL into RPN that is
65 sent to the server, enabling CQL to be used against all Z39.50
66 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
67 ZOOM_query object, and submit it using ZOOM_connection_search().
68 The CQL-to-RPN translation uses a configuration file, the name of
69 which must be specified in the Connection's "cqlfile" option.
71 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
72 function, which takes as its start-term parameter a ZOOM_query object
73 (which may have had either CQL or RPN set into it).
78 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
79 GFS to support this as well. Backend handler, bend_srw_update, does the
80 update work. Code contributed by Ko van der Sloot.
82 Allow retrieval of Search Result-1 information in ZOOM by the use of
83 options that are attached to a result set. ZOOM documentation updated
86 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
87 UTF-8 conversion. Patch by Raj Patel.
89 Added option -m to GFS to control formatting of timestamps in log file.
91 Added 'exit' as synonym for 'quit' in yaz-client
93 Added support for specifying SRW resultSetId + resultSetIdleTime in a
94 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
95 for the new members. Patch by Ko van der Sloot.
97 Added support for SRU POST. It is supported for content-type
98 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
100 Do not build the separate Multi-threaded (MT) library libyazthread.la.
101 Instead make the library libyaz.la multi-threaded. Threading as a whole
102 can still be disabled by configure option --disable-threads. Previosly,
103 with older GLIBCs there were problems with MT libs under Apache. This
104 has now been fixed a long time ago.
106 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
109 CQL module modified to be case insensitive for relations/indexes/operations.
111 Fixed bug in CQL transform code: incorrect value relationModifieder
114 Added 'show all' command for yaz-client which retrieves all results
117 Added new yaz-client, xmles, which takes a (private) OID and
118 a document to be sent as an extended service request.
120 Describe new yaz-client commands wait_response and set_auto_wait.
122 Increase TCP/IP listener backlog from 3 (which I am guessing was
123 copied from the SunOS manual entry way back when) so SOMAXCONN, so
124 that the socket will queue as many incoming connections as it's able
125 to handle ongoing connections. In other words, it will never now
126 refuse a connection that it would be able to handle merely because
127 it's not got around to accepting() enough of the pending connections
128 yet. This is the behaviour anyway under Linux, where the listen()
129 argument is ignored; but not under BSD and on systems such as
130 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
131 YAZ-based servers should now be uniform across operating systems in
134 yaz-marcdump uses 64-bit file access on some systems. This is enabled
135 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
136 This allows yaz-marcdump to read large MARC batches (>2 GB).
138 Modified all YAZ source files - except the source which is auto-generated
139 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
142 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
143 corresponding to the existing *_setl() function. These allow option
144 values containing arbitrary valuues.
146 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
147 ZOOM_resultset_sort() in new applications. Its behaviour is identical
148 except that it returns an indicator of whether or not the sort
149 criterion was accepted (0 for OK, -1 for invalid).
153 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
154 MARC output rather than returning "new" buffer.
156 yaz-client warns about unknown init options.
158 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
162 Added support for SRW sort in Generic Frontend Server. Patch
163 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
164 sortKeys - or NULL if none is provided.
166 Fixed bug #307: It was impossible to specify indefinite/no timeout
167 for ZOOM_event. Special timeout value -1 now means indefinite timeout
170 Added support for multiple languages and charsets to be specified in
171 ZOOM. Each charset/language is separated by a blank. If negotiation is
172 in effect in init-response, Option
173 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
174 Code based on patch by Vasiliy Osadchuk.
176 Fixed bug #306: infinite recursion that occurred when calling
177 yaz_log_level_init as the first call (before other log level or
180 Fixed bug in scan handling in front end server: if preferred-Position-In-
181 Response was non-present, a NULL pointer referece was performed.
185 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
186 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
187 now defined for all those error codes. So instead of putting 109 in
188 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
189 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
191 Modified the yaz-marcdump utility to skip garbage bytes between MARC
194 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
196 Program yaz-client now exits and produces an error message if multiple
197 Z39.50 servers are specified on the command line (none or one allowed
200 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
205 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
207 Fixed bug #272: Preserve spacing for CCL terms.
211 Added support for virtual hosts and multiple backend servers for
212 the YAZ frontend server. The configution is XML based and
213 support specificition of CQL to RPN mappings and explain information.
214 See section "Virtual Hosts" in the YAZ manual.
216 Extended OPAC display utility. OPAC display utility renders
217 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
218 to supplement yaz_marc_decode_wrbuf.
220 Fixed a bug in MARC decoder that could caused it to crash for some
221 invalid MARC records. More diagnostics and warnings where added in
222 XML output (warnings, etc are stored in comments).
224 --- 2.0.34 2005/02/08
226 Fixes for UNIX domain sockets. Bug #261.
228 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
230 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
231 Added yaz_marc_subfield_str which defines subfield lead string which is
232 used in YAZ_MARC_LINE format. Default string is blank+$. Added
233 yaz_marc_endline_str which defines end of fields string used in
234 YAZ_MARC_LINE format. Default string is newline.
236 Experimental support for MarcXChange. This format can be produced
237 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
238 http://www.bs.dk/standards/MarcXchange.xsd
240 Added yaz-client commands scansize that sets maximum number of
241 entries to be returned by scan.
243 --- 2.0.32 2005/01/11
245 Added support for SRW scan in yaz-client and Generic Frontend Server.
247 * Added whereInList member to SRW Scan Term.
249 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
251 Fixed NMEM system to return aligned blocks on the smallest boundaries
252 that are suitably aligned for all possible types on the particular
253 architecture YAZ is being built for.
255 --- 2.0.30 2005/01/04
257 Fixed numerious warnings that was issued with newer versions of GCC.
259 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
260 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
263 Make YAZ Generic Frontend Server slightly faster.
265 Enhance (and reduce) logging for Generic Frontend Server.
267 Revert YAZ log system so that it flushes every write operation
268 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
270 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
271 instead of LOG_, due to name clash with syslog(3). LOG_ are still
272 present. New applications should define YAZ_USE_NEW_LOG=1 - this
273 will effectively disable old definitions.
275 --- 2.0.28 2004/11/09
277 Added yaz_log_time_format which specifies log format using
280 Added yaz_log_module_level which returns mask for a module. Value
281 is non-zero mask a if module is enabled; zero if disabled.
283 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
284 in include/yaz/cql.h.
286 Fixed bug #176: Dont throw diagnostics on empty SRU args.
288 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
290 Fixed bug #172: RPM builds does not enable SSL.
292 Doxyfile.in part of dist. Doxyfile generated by configure.
294 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
295 are given and the corresponding component does not exist.
297 Extend CCL documentation in YAZ reference. Describe r=r.
299 --- 2.0.26 2004/10/01
301 Fixed MARC->MARCXML conversion to properly deal with
302 fields, subfields, indicators having non-ASCII characters.
304 Fixed MARC->MARCXML conversion so that ASCII control characters
305 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
308 Added YAZ GFS support for conversion from Z39.50 surrogate
309 diagnostics to SRW surrogate diagnostics.
311 Bug fix: YAZ GFS did not return schema in explainResponse.
313 --- 2.0.25 2004/09/30
315 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
316 now converts recordSchema to elementSetName as well as schema URI.
318 Fixed bug in COMSTACK that prevented HTTP request packages from being
321 --- 2.0.24 2004/09/29
323 Added CCL facility r=r "range" which is similar to r=o "ordered" but
324 does not require white-space before and after the dash in a range, e.g.
325 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
328 Fixed a few AC_TRY_LINK configure tests that did not operate properly
329 due to new GCC removing "redundant" code.
331 Added yaz-client commands scanpos and scanstep that sets preferred
332 position and step-size for scan.
334 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
336 Added CCL utility ccl_qual_buf which parses one or more CCL
337 spec lines in a buffer.
339 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
340 of name and value - ignoring empty lines and comments.
342 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
344 Added odr_get_element_path which returns current element path for an
345 ODR handle. This utility is useful in error handling or user-defined
348 Added ODR_PRINT utility odr_set_stream which is is a more generic
349 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
350 to a write function and pointer to close function. The close function - if
351 non-NULL - will be called during odr_destroy.
353 Fixed bug in CCL parser where truncation char was not removed from
354 right side when truncation=both was in effect.
356 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
359 --- 2.0.23 2004/08/11
361 Fix buffer overrun in CQL parser when dealing with proximity (%).
363 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
364 to UTF-8/UCS conversion is now only based on codetables.xml.
366 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
368 --- 2.0.22 2004/08/06
370 Add support for more "commit changes" in ZOOM (uses Extended Services).
372 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
375 Yet another small fix for configure of SSL.
377 --- 2.0.21 2004/05/14
379 Fix SSL libs for configure when --with-openssl=DIR is given.
381 --- 2.0.20 2004/05/10
383 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
385 SSL comstack now uses yaz.pem certificate file on server side
386 by default. Certificate filename can be configured by calling
387 comstack function cs_set_ssl_certificate_file before cs_bind is used.
389 Fix bug regarding multiple calls to ZOOM_connection_connect.
391 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
393 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
394 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
396 ZOOM now allows inspection of X509 peer certificate for verification.
397 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
399 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
400 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
401 as "modular" but it simplifies things.
403 Added cs_get_peer_certificate to that returns peer X509 PEM.
405 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
406 NULL if SSL is unavailable.
408 Documentation about MARC decoding tools.
410 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
412 --- 2.0.19 2004/03/30
414 Rename CHANGELOG to NEWS to follow GNU style packing.
416 Fix bug with missing initialization of member in init_diagnostics.
417 This bug affects threaded version of GFS server.
419 --- 2.0.18 2004/03/20
421 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
424 Ensure zlib.dll is packed with Windows install.
426 --- 2.0.17 2004/03/17
428 Fix encoding of xsd:string to use text instead of CDATA.
430 Fix endless loop in CQL parser with unbalanced ".
432 Use a more compact way to store MARC-8 conversion tables.
434 --- 2.0.16 2004/03/16 Debian only
436 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
439 Update CQL parser to use new CQL 1.1 modifiers for booleans and
444 --- 2.0.15 2004/03/01
446 Another fix for decoding of XML packed records.
448 --- 2.0.14 2004/02/25
450 Fixes for Chunked encoding. White space not ignored after length spec.
452 Update NS and use default NS for SRW diagnostic elements.
454 --- 2.0.13 2004/02/23
456 Implement ZOOM_resultset_cache_reset which resets record cache.
458 Implement ZOOM_resultset_sort which sorts a result set.
460 Implement chunked HTTP transfer.
462 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
464 --- 2.0.12 2004/02/16
466 Added member 'schema' to bend_explain_rr structure so that backend
467 can specify explain record identifier. Defaults to Zeerex 2.0.
469 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
471 --- 2.0.11 2004/02/16
473 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
476 Added init command for yaz-client which sends "extra" init request.
478 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
479 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
481 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
483 Make ZOOM error code for "invalid query".
485 Fixed compilation for SSL which wasn't properly enabled for all platforms.
487 --- 2.0.10 2004/02/05
489 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
492 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
494 Added option -p <file> to make Generic Frontend Server to write PID file.
496 Added option -D to put Generic Frontend Server in background on its own.
498 Make ZOOM C recognize option "password". If unset, "pass" is used
499 (for backwards compatibility).
501 Fixed a bug in Generic Frontend Server that could make it crash if a
502 client sets characterSetNegotation bit, but didn't pass negotiation stuff
505 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
506 Must be issued before open, in order to be in effect.
508 --- 2.0.9-6 2004/01/12 Debian/Windows
510 Make the SRU server more picky WRT unknown params, etc.
512 Bug fix: ZOOM scan response didn't return displayTerm - when present.
514 New YAZ client command, options, that sets Z39.50 options.
516 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
517 options from a string of tokens (one token for each option bit).
519 Update SRW diagnostic code messages.
521 --- 2.0.9-5 2004/01/07 Debian/Windows
523 Handle user defined stylesheet for SRW/SRU.
525 --- 2.0.9-4 2004/01/06 Debian/Windows
527 Fix bug in decoding of Content-Length.
529 --- 2.0.9-3 2004/01/06 Debian/Windows
531 Fix a bug with decoding of XML packed records.
533 --- 2.0.9-2 2004/01/05 Debian only
535 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
537 Fix bug in SRW/SRU diagnostics decoding.
541 Fixed bug in Generic Frontend Server which could drop records exceeding
542 preferred message size. Reported and fixed by Irina Dijour.
544 Fixed calculation of package size for structured records in Generic
545 Frontend Server. Reported and fixed by Irina Dijour.
547 Fixed namespace for SRW/SRU diagnostics.
549 Fixed SEGV in yaz-client that occured for HTTP connection errors.
553 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
554 this version is incompatible with version 1.0 and older YAZ SRW/SRU
557 CQL changes to reflect recent changes to the specification:
558 * Documentation talks about context sets instead of index sets.
559 * Documentation talks about indexes instead of qualifiers.
560 * The CQL-to-PQF transformer's configuration file now uses
561 "index.set.name = <attributes>" instead of the old form
562 "qualifier.set.name = <attributes>". (Both forms are still
563 understood but the latter is deprecated.)
564 * CQL terms with no explicit index specified are now interpreted as
565 cql.serverChoice instead of srw.serverChoice (which of course
566 behaves exactly the same.)
570 MARC conversion can now generate ISO2709 output in another
571 character set. yaz-marcdump uses this facility if you invoke it
574 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
575 functions from there can be used from C++.
579 Frontend server now transfers memory from decoded packages to stream
582 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
583 references to show up.
585 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
586 the ZOOM Abstract API. The older names for the same options are still
587 also supported for the benefit of old applications.
589 ZOOM-C supports "implementationId" and "implementationVersion" options
590 to go along with "implementationName". These allow the user code to
591 specify identification strings to be sent to servers.
592 Add OID for the new ExtLite attribute set.
594 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
595 as requested/supplid by Ere Maijala <ere@atp.fi>
597 For generic frontend server, reverse the order of
598 "toolkit-supplied / application-supplied" strings sent as implementationId,
599 Name and Version. Also, remove the spaces around the slash. This brings
600 the GFS in line with the behaviour of ZOOM-C on the client side.
602 Add function ZOOM_scanset_display_term.
604 yaz-client shows scan displayTerm if present.
606 Utility yaz-iconv is now installed by default along with the man page
609 Extend configure check for OpenSSL to use pkg-config where available (such
612 Incorporate patch by Morten Bogeskov which allows a Unix file socket
613 server to specify uid/gid/mask for socket using the format
614 unix:[user=uid,][group=gid,][umask=mask,]file=path
615 If file= is omitted the existing format is assumed, e.g.
617 in which case the mask is 0666 (rw for everybody).
619 Major restructure of YAZ source. All source in libyaz is in src directory.
620 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
621 util (utility programs such as ASN.1 compiler, yaz-marcdump).
623 Added man page for utility yaz-marcdump (used to be called marcdump).
624 yaz-marcdump is installed by 'make install'.
626 Fixed a memory leak in Generic Frontend Server that occurred when decoding
627 of incoming package failed.
629 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
631 Change prototype of odr_perror: add const to message string.
633 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
635 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
636 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
637 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
638 DNS lookup. There should not be any compatibility problems with this
639 assuming that blocking=1 or 0 is used.
641 Fix bad reference in UNIX comstack in function cs_addrstr.
643 Fix for compilation on AIX.
645 The generic front-end server (server/seshigh.c) now supports returning
646 Init diagnostics to the client in User-information-field, in
647 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
652 Allow any CQL relation (not just all,any,exact,scr).
654 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
655 that features the same UI.
657 Implemented command update0 in YAZ client which is equivalent to
658 update but uses old of Ext Update ASN.1.
660 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
661 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
662 Previously no OID was used for this info.
664 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
665 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
666 returns 'malformed search term' otherwise.
668 SortResponse member resultCount now set to NULL in sort handler of
671 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
674 Add three new utility functions for translating OIDs between various
675 formats -- symbolic name such as "Usmarc", minus-1-terminated int
676 arrays and dotted strings such as "1.2.840.10003.9.5.1":
677 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
678 char *oid_to_dotstring(const int *oid, char *oidbuf);
679 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
681 Reverted modifications for ES Update definition for z_IU0Update
682 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
683 is back to YAZ 2.0.2.
685 String value attributes for CCL parser.
687 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
688 which their FirstSearch server returns in Init responses, sometimes
689 carrying useful diagnostic information when Init fails. This has the
690 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
691 "z39.50/oclcui.asn", where its definition is somewhat different from
692 what OCLC document on their web-site, as required to interoperate with
695 Support for anonymous authentication in yaz-client. Use the command
698 * Fix the OID of the Index Data-local "admin" Extended Service from
699 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
700 the 1000, which indicates a locally-defined OID, was a mistake.
704 Fix CCL directive @case handling so that it affects string match for
705 both CCL keywords and qualifiers.
707 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
708 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
709 Decoder has been updated with ASN.1 changes as listed in
710 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
711 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
712 z_IUUpdate, remains unchanged.
714 ZOOM_record_get may now return a record in a specific character set.
715 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
716 "from" is the character set of record as returned by target. "to" is
717 the character set to be returned. If omitted, "to" is UTF-8.
719 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
721 New ODR utility, odr_getelement, which returns name of element for
722 which encoding/decoding failed.
724 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
725 in cases where a required element was omitted.
727 Bug fix: some MARC8 sequences were not converted.
729 New ZOOM option "step" which specifies number of records to be
730 retrieved in one chunk. Used in conjunction with "start" and "count".
732 SRW support for yaz-client. Use scheme http: to use it, e.g.
735 yaz-client no longer does (un)intelligent character set conversions
736 by default. Can be enabled with charset and marc_charset commands.
738 xmalloc trace fix for 64-bit systems such as DEC alpha.
740 Solaris 2.6 compile fix.
742 New function, cql_strerror() translates SRW error codes, as returned
743 by cql_transform_error(), into human-readable English strings. Used
744 in yaz-client diagnostics when appropriate.
746 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
747 converts it into a type-1 query which is sent to the server. This
748 makes CQL available for use with all Z-servers, as opposed to the tiny
749 minority that can handle CQL queries themselves.
753 New Debian package layout similar to the Redhat Package layout.
755 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
756 and search result respectively.
760 Redhat package is now several packages: libyaz (runtime libraries),
761 libyaz-devel (development and documentation, and yaz (utility programs).
762 Package spec file by Morten Bøgeskov.
764 New member 'schema' in struct bend_fetch_rr which the name of requested
765 schema (SRW/SRU) for record (or NULL if none was given). The fetch
766 handler MAY set this to reflect the schema of the returned record.
768 New member 'display_term' in struct scan_entry. GFS now sets member entries
769 and allocates scan entries to be filled by user scan handler. In previous
770 version, entries member was allocated by the scan handler. That still works,
771 but the GFS will ignore member display_term - assuming it was NOT set by
772 the handler. The fact that the GFS now allocates the entries both allows
773 for new members and makes a scan handler easier to write.
775 Fix CQL lex buffer overflow.
777 SRW/SRU recordPacking. For SRW default recordPacking is string. For
778 SRU default recordPacking is string.
780 SRU protocol support for frontend server.
782 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
784 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
786 Added scan for the ZOOM shell (zoomsh).
790 * String Identifers for Schemas (Amendment 5).
791 http://lcweb.loc.gov/z3950/agency/amend/am5.html
792 Old definition for schema
793 Odr_oid *schema; /* OPT */
798 Z_InternationalString *uri;
799 #define Z_Schema_oid 1
800 #define Z_Schema_uri 2
803 * resultCount parameter to Sort Response (Amendment 1).
804 http://lcweb.loc.gov/z3950/agency/amend/am1.html
806 Support for SRW 1.0 over HTTP. This is an optional feature and
807 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
810 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
811 on the same port. SRW SearchRetrieveRequests are mapped
812 to bend_init,bend_search,bend_fetch,bend_close.
814 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
816 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
817 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
819 ZOOM connections are SRW based if schem http is used for hostname
820 in connect, e.g. z = ZOOM_connection_new("http://myserver");
821 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
823 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
824 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
825 distance=n, order=true/false, relation=le, prox unit=word. If
826 n is omitted, distance 1 is used.
828 Fixed problem with C compiler include path in wrong order.
830 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
831 on Solaris. Patch from Ko van der Sloot.
833 New MARC decode API. All new functions operate on a yaz_marc_t
834 handle. The most important new functions are: yaz_marc_create,
835 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
836 decode and destroy respectively. Decoder can produce formats
837 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
838 include/yaz/marcdisp.h.
840 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
841 to UTF-8, UCS-32, wchar_t or Latin-1.
843 * Prototypes for yaz_iconv_-functions moved to separate header
844 include/yaz/yaz-iconv.h.
846 Make a few private functions 'static' in unix.c. This prevents
847 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
849 For ZOOM connection, the options targetImplementation{Id,Name,Version}
850 are set when Init Response is received.
852 New function ZOOM_connection_error_x similar to ZOOM_connection_error
853 but returns diagnostic set as well.
855 New function yaz_strerror which is a portable wrapper for
856 strerror/strerror_r/GetLastMessage.
858 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
859 is returned for MARC. If type is "oai", then OAI MARC is returned.
861 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
866 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
868 Fix bad race conditions on SIGTERM and terminate gracefully in
871 Move retrieval (data1) module to Zebra since nobody seems to be
874 Add GRS-1 render for ZOOM using same format as yaz-client.
878 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
880 Fix broken ESpec handling in data1 module.
882 SGML reader parses comments and makes them part of the data1 tree.
884 Added several type casts so that YAZ compiles as C++ code.
886 ZOOM didn't handle PDU encoding failures properly.
888 Added more Bib-1 diagnostics (approved extensions).
890 GNU configure: better check for iconv.
892 More portable use of accept, getpeername. Check for socklen_t. Use
893 int/size_t if socklen_t is not defined.
897 PQF parser rejects bad queries - including those with extra
898 characters in them. PQF parser used to silently ignore that.
899 Cleaner API for PQF added, which allows you to get detailed
900 error information for bad queries (see yaz/pquery.h).
902 Fixed bug in ZOOM_record_get for type "database".
904 Implemented mini iconv library supporting conversions between
905 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
907 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
911 Fixed ZOOM C record cache so that preferredRecordSyntax and
912 elementSetName is used to check for already fetched records.
916 Added three members in bend_initrequest structure to facilitate
917 character set negotiation.
919 Fixed a bug in frontend server that could cause indefinite
920 loops under rare conditions.
922 Revised character set utilities (charneg.h) so that encoding
923 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
925 For PQF, directive @term <type> sets term type for Scan/Search.
926 Here <type> is general, string, numeric, null. The term type
927 is inherited - just like @attr.
929 New call odr_set_charset that sets character set conversion for
930 international-strings on a ODR stream. Prototype is:
931 int odr_set_charset(ODR o, const char *to, const char *from);
932 The InternationalString is still represented as C string in YAZ
933 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
934 won't). On the protocol level, you can use any encoding.
936 Support for UNIX sockets in ZOOM.
938 Solaris recv sometimes returns errno == ENOENT. It is treated as
939 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
941 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
942 both client and server. Code by Morten Bøgeskov.
946 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
947 that they can be used directly from Visual Basic. You must recompile
948 your windows APP if you're using ZOOM.
950 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
951 Commands "lang" and "charset" sets language and character set respectively.
952 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
953 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
955 Attributes from multiple CCL fields may be OR'ed rather than merged
956 using directive "@field or". Fields are still merged by default -
957 equivalent to "@field merge".
959 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
962 Fixed bug in zget for parameter ExtendedServicesResponse.
968 Added PQF feature: '@attr type=value' may be written as '@type=value'.
970 Client displays USR.1:SearchResult-1 (hits per term).
972 Additional Search Info for search in Generic Frontend Server.
974 Fixed CCL parsing of "field=s".
976 WIN32 installer - using the excellent NSIS software from nullsoft.
978 Fixed CCL parsing of "field = - <number>".
980 Added function yaz_marc_decode that decodes MARC for line mode
981 display or XML (similar to that used by JZKit).
983 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
984 Z39.50. But ISO/ILL was, however.
986 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
987 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
989 http://lcweb.loc.gov/z3950/agency/amend/am2.html
990 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
994 New YAZ client features: Command completion and new commands:
995 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
996 Code provided by Jacob Poulsen.
998 New call oid_trav, that visits all registered OIDs via callback.
1000 Function ZOOM_record_get now returns const char pointer rather than
1001 void pointer. It saves a lot of type casts.
1003 For YAZ client, command "auth" now allows you to set authentication
1004 in IdPass style. It is enabled when three tokens are given - order
1005 is user, group and password.
1007 Fix memory leaks in MARC record handling for ZOOM.
1009 New option for YAZ client, -k <kilobytes> that sets
1010 maximum record size. Similar to -k option for generic frontend
1011 server and yaz-ztest.
1013 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1015 Prefix query parser reports "fail" when bad attribute set is given.
1017 Fix in MARC decoder. Proximity logging. Fix for attribute set
1018 in scan handler for server. Patches by Shigeru Ishida.
1020 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1023 Configure option --with-openssl=<dir> now works when a directory is
1024 specified. Patch provided by Morten Bøgeskov.
1026 New option for YAZ client, -u <auth>, that sets authentication.
1028 ZOOM fix: error information was sometimes "missing", since error
1029 was cleared/reset too when it shouldn't.
1031 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1033 --- 1.8.4 2002/01/04
1035 Scan for ZOOM API. New object ZOOM_scanset. New functions
1036 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1037 ZOOM_scanset_destroy.
1039 New ZOOM function, ZOOM_connection_last_event, that returns type
1040 of last event (such as "receive data", "send data", "apdu received",
1043 New ZOOM option, schema, that specifies schema for retrieval.
1045 New CCL feature. Qualifiers can be aliases for one or more
1046 other qualifiers (if more than one is given, OR is used).
1048 ZOOM uses named result sets if target supports it.
1050 Two new YAZ client commands: . (dot, which sources a script of YAZ
1051 client commands), and ! (to execute shell command.). Implemented
1054 Working on Debian packages.
1056 --- 1.8.3 2001/11/19
1058 YAZ client enables named result sets only if target supports it.
1060 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1062 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1063 with key="host" to get same result.
1065 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1066 Function Z3950_resultset_record(s) returns references to records
1067 "owned" by resultset. To become owner use Z3950_record_clone.
1069 Function z_ext_record handles Extended Services. Thanks to
1072 --- 1.8.2 2001/11/12
1074 CCL Parser fix: ignore token comma when dealing with and-lists.
1076 Documentation updates for COMSTACK.
1078 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1079 Changed prototype Z3950_records. For some functions, int parameters
1080 were changed to size_t.
1082 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1085 New MARC decode/display function, marc_display_exl, which properly rejects
1086 non-ISO2709 records. YAZ client uses it.
1088 --- 1.8.1 2001/10/29
1090 Fix bug: local attribute set wasn't set correctly in PQF strings.
1094 * Old Z39.50 codecs no longer supported.
1096 Added ZOOM C binding. See http://zoom.z3950.org/
1098 Renamed states for COMSTACKs to avoid confusion with events.
1100 Implemented cs_look and proper cs_rcvconnect.
1102 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1104 Configure detects POSIX threads on OpenBSD.
1106 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1107 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1109 When error is returned from present handler, non-surrogate diagnostic
1110 is returned in present response (and fetch handler is no longer called).
1112 * Minor adjustments to pquery parser (PQF). Token characters may be
1113 escaped by using backslash (C-style).
1115 PQF parser allows string attribute values to be specified. For @attr,
1116 non-numeric characters after the equal-sign are treated as strings
1117 (e.g. @attr 9=title).
1119 CCL trunction character may be defined (@truncation in file)
1121 * function zget_ExtendedServicesRequest sets waitAction to
1122 waitIfPossible (was wait).
1124 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1127 CCL operator names may be set in field definition files (CCL_bibset).
1128 See ccl/bib1 for an example.
1130 Fixes in ASN.1 compiler for C++ compatibility.
1132 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1133 and "op_or" to avoid conflict with C++.
1135 Fixed problem with GNU readline detection on Redhat 7.0.
1137 Added step-size for Scan backend handler.
1139 Fixed bug that made the frontend server crash when no attribute
1140 set was specified for scan.
1142 Front-end server automatically switches to original working directory
1143 when installed as an NT service. Previously -w had to be specified to
1146 Added extended attributes for retrieval module (data1), so that data1
1147 records carry d1_readXML/SGML attributes. d1_read also supports
1148 null-data rules ( <tag/>)
1150 On UNIX when POSIX threads are available, a separate library libyazthread
1151 is created. Programmers should link with that library and the yaz library
1152 when using threads. The reason for the split was that some applications
1153 on Linux, such as Apache, doesn't work well when using shared objects that
1156 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1157 (or any frontend server) in SSL mode by specifying ssl: followed by
1158 address. Only tested on UNIX.
1160 Added feature for CCL module. Virtual structure s=al or s=ol generates
1161 and-list and or-list respectively instead of phrase search.
1165 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1166 log_mask_str. This was done to avoid name conflicts with other libraries
1167 (such as other PHP extensions).
1169 Added raw OID member for preferred record syntax (request_format_raw)
1170 and returned record syntax (output_format_raw) for backend fetch method.
1172 Config file yaz-config now accepts options so that it returns specific
1173 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1175 Shared library support for UNIX using GNU libtool.
1177 * Modified backend interface. Request/Response struct's replaced by
1178 one read/write C struct. For example bend_fetchrequest and
1179 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1180 Every handler - even search has to be registered in bend_init
1181 handler. This means that the YAZ library no longer refers to
1182 external functions and it makes it possible to make the whole
1183 thing a single DLL/SO.
1185 Added Segment handler for backend server.
1187 Added Zmbol/Zebra administrative functions to YAZ client.
1189 Threaded frontend server on UNIX (when POSIX Threads are available).
1190 Starting the server with option -T enables multi-threading.
1194 Added configure option --enable-comp/disable-comp to control use
1195 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1196 located in sub directory asn.
1198 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1199 in ${exec_prefix}/bin along with the other programs yaz-client and
1202 GNU automake used to maintain makefiles.
1204 Added several OID's.
1206 Changed retrieval module so that we can load records with no abstract
1207 syntax defined. Tagpaths in these records are fully composed of string
1210 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1214 On UNIX, the generated makefile now supports a proper 'make install'.
1215 The prefix can be set via GNU configure to set the install location
1216 (default is /usr/local).
1218 * YAZ programs client and ztest were renamed to yaz-client and
1219 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1220 locations, such as /usr/bin,/usr/local/bin,etc.
1222 * YAZ Header files were moved from include to include/yaz. YAZ Header
1223 files are referred to as include <yaz/log.h> rather than <log.h>.
1224 The YAZ include path (-I ..) is therefore the same as before. Programmers
1225 should update their #include statements or use -Ipath/include/yaz
1226 instead. The main motivation for doing this change is that YAZ header files
1227 can be installed in "standard" locations /usr/include,/usr/local/include
1228 without introducing conflicts, since ALL YAZ header files are stored
1229 in subdirectory yaz (under /usr/include for example).
1231 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1232 rather than project/workspace files. We switched because project files
1233 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1236 Changed name of logging function, logf, to yaz_log, to prevent name
1237 clash with some math-log functions. The YAZ header log.h defines logf
1238 to yaz_log (#define) so there should be no incompatibilities by this
1241 Added bend_start/bend_stop handlers for server. These handler are
1242 called on start/stop of server. For windows they are called whenever
1243 a service is started/stopped.
1245 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1246 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1247 in util/yc.tcl. The auto-generated C code structures are, in a few
1248 cases, incompatible with the old decoders. There are differences in the
1249 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1250 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1251 The preprocessor variable ASN_COMPILED is defined when the compiled
1252 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1253 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1254 wish to use the old encoders/decoders you can specify --disable-yc
1257 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1258 version so that it supports both new - and old version of DB Update
1260 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1261 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1262 change. The name parameter can be set to 0 in which no name is specified
1263 for the construction. The macros odr_implicit and odr_explicit sets name
1264 parameter to zero for the construction involved. New macros
1265 odr_implicit_tag and odr_explicit_tag are similar to the others,
1266 except that a name parameter is added. For programmers' that don't use
1267 ODR they probably only need to change the call to z_APDU and z_External.
1269 Added access control facility by interfacing the TCP wrapper library.
1270 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1271 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1272 name of the daemon and enables the access control as specified in
1273 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1275 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1276 den Dool <H.M.vdnDool@kub.nl>.
1278 Added reference ID parameter to most functions in server API - refer
1279 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1281 Changed name of ccl library to libccl.a (was ccl.a).
1283 Fixed bug in decoder for Explain (Category TargetInfo).
1285 Added support for GNU readline in client. Thanks to Jacob Poulsen
1286 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1288 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1289 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1290 IMPLEMENTATION! This change was made to the development version before
1291 the ZIG decided to retract the amendment. If any users MUST be
1292 compatible with the original Update definition, PLEASE CONTACT US, and
1293 we will include a separate definition corresponding to the old Update
1294 ES. Note that because of the change to the ASN.1 of the
1295 TaskPackageRecordStructure we cannot define a single structure that
1296 will support both versions.
1298 * Added const modifier to buffer parameter for some ODR/BER encoding
1299 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1300 completeWAIS, odr_dumpBER.
1302 Fixed bug in client.c which caused a crash when a scanResponse didn't
1303 contain positionOfTerm.
1305 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1306 * will cause an error in a client if a non-YAZ target sends both a
1307 * list of Scan entries and non-surrogate diagnostics.
1309 Retrieval module enhancements. Tag sets may be typed in the reference
1310 to it. From the .abs-file the "tagset" directive takes a third optional
1311 integer type for the tag set referenced. From a .tag-file the "include"
1312 directive takes a third optional type as well. The old "type" directive
1313 in the tag set itself is still recognized but acts as the default type
1316 Backend interface change. Individual Scan terms returned from bend_scan
1317 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1318 in include/backend.h.
1320 Retrieval module enhancements. Multiple tag sets and attribute sets may
1321 be specified in abstract syntax specs. Revised the error/warning for
1322 logging messages reported by the retrieval module when reading the
1325 Object Identifier system (oid_..) changed. The API is backwards
1326 compatible but the oid-routines now allocates new OID's when needed.
1327 Raw OID's may be specified in oid_getvalbyname.
1329 YAZ now uses GNU configure to generate Makefile(s).
1331 * Minor changes in some of the member names of DeleteResultSetRequest and
1332 DeleteResultSetResponse. See include/proto.h.
1334 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1335 and added member 'languages' in TargetInfo (which was missing).
1337 Changed the way attribute sets are handled in the retrieval
1338 module. These are now cached, just like the abstract syntaxes
1341 Changed YAZ so that it links with compiled ASN.1.
1343 Added Explain-schema definitions and mapping routines. The following
1344 Explain categories have been implemented: AttributeDetails,
1345 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1347 Fixed minor bug in Windows version of Server Library.
1349 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1351 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1353 Added EXTERNAL: UNIverse Resource Report (non-standard).
1355 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1356 ENUMERATED and SET OF.
1358 * Added 'const' to some of the char pointer arguments for the
1359 functions, data1_read_node, data1_getelementbytagname,
1360 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1363 Fixed bug in data1_insert_taggeddata - the last_child member of
1364 parent wasn't initialised.
1366 * Changed data1_read_record and data1_read_node so that the supplied
1367 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1368 doesn't refer to any parts of the "SGML"-buffer.
1370 Fixed bug in server library (Windows version of statserv_remove).
1372 * Changed code so that it compiles as C++. The type definition
1373 of Odr_fun which is a member of Odr_arm was changed. The result is,
1374 that an explicit typecast is needed for the fun pointer when
1375 using Odr_arm - as in:
1376 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1378 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1380 Implemented the new structured date and time definition as approved
1381 by the ZIG. Added schemaId element to the specificTag in Espec-1
1382 (also approved at the last ZIG). Thanks to RVDM.
1384 Added some Object identifiers (RVDM).
1386 Changed the Update Extended Service (RVDM).
1388 Added command "refid" to client which specifies referenceId for
1389 the following requests.
1391 Implemented extended service handling for server. See ztest.c
1392 for an example as well as backend.h. New handlers are registerd
1393 in the Init handler.
1395 * Changed interface for sort in server.
1397 Added new members to statserv_options_block. It allows a server
1398 to read options from another source than just the command line. Thanks
1399 to Charles Woodfield.
1401 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1402 renamed to zboolean. Some C++ compilers complained about the name.
1404 Minor changes to gils.abs. Added index 's' (sort) on title
1405 and date/time-last-modified.
1407 --- 1.4pl2 1998/1/30
1409 Fixed bug in server library regarding inetd mode (-i). This bug
1410 was introduced by release 1.4.
1412 --- 1.4pl1 1998/1/29
1414 Added sort facility in client and backend server interface.
1416 Fixed problem with dependencies in Makefile(s).
1418 Fixed bugs for encoders/decoders of extended services and
1421 Implemented sub-tree feature for schemas. Sub-trees are
1422 referenced in *.abs-files. See explain.abs for an example
1423 of the use of this feature.
1425 Modified bib1.att; local attributes for ANY didn't include
1426 ANY itself (only affects use of the retrieval module).
1428 Fixed bug in plain SGML reader in function data1_read_node:
1429 tags with prefix "var" was incorrectly interpreted as variants.
1431 Added feature "sub-schemas" to enable references to - and definitions
1432 of - group of elements.
1434 * Removed member parent from type data1_element (in data1.h).
1436 Implemented function odr_nullval() that returns the value of
1439 * Removed member num_children from data1_node (in data1.h).
1441 Made NT service interface part of the server library. The
1442 function statserv_main uses the NT service when required and
1443 calls the statserv_start / statserv_close routines.
1445 Routine zget_SearchRequest and zget_PresentRequest fills
1446 resultSetName/Id member with "default" instead of "Default".
1448 Fixed memory leak in server. Request queue member wasn't freed.
1450 Fixed nmem_exit so that memory is freed.
1454 Revised the CCL parser utility to be thread safe.
1456 Added function, oid_ent_to_oid, to replace the function
1457 oid_getoidbyent, which is not thread safe.
1459 * Added nmem_init and nmem_exit to initialize and release
1460 NMEM resources. Function nmem_init should be called once in the
1461 initial thread before NMEM/ODR is used. statserv.c and client.c
1462 have been changed accordingly. The change was necessary to make
1463 NMEM thread safe. The NMEM memory pool is shared amongst threads
1464 in a process. Unix-based applications will still work fine without
1467 Added NT Services interface for the the Z39.50 (statserv) Server.
1468 Refer to the ztest.c source on the usage.
1470 Windows 95/NT port using MSVC5.0. Project files are included in the
1473 * Defined new 'global' handle for the retrieval (data1) system. The
1474 new handled, data1_handle, describes the state of the data1 system.
1475 This handle is passed as first argument to virtually all
1476 data1 related routines. The functions data1_create and data1_destroy
1477 creates and destroys a data1 handle respectively.
1479 Added ODR encode stream member to all backend request structures
1480 init, search, scan etc. This stream should be used to allocate all
1481 memory used for the response when thread safe operation is needed.
1483 Changed the comstack utility, cs_addstr, to be thread safe. The
1484 returned hostname string returned by the function is now part the
1487 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1488 function. The cs_straddr takes a COMSTACK handle as argument, so this
1489 function must be used after cs_create and before bind/connect.
1490 This function is thread safe.
1492 Moved test server to 'ztest' directory - generic server code still
1493 in 'server' directory.
1495 Made prefix query (pquery.c) utility thread safe.
1497 Added new function modifier YAZ_EXPORT to 'export' public DLL
1498 functions when using windows (see include/yconfig.h).
1500 Added definitions to the OID database (util/oid.c) (RVDM).
1502 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1504 Added call to ccl_rpn_delete in client program.
1506 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1507 release of RPN structure.
1509 Added support for C++, headers uses extern "C" for public definitions.
1510 With input from RVDM.
1512 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1513 Thanks to Ronald van der Meer (RVDM).
1515 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1517 Added support for private extensions to the OID database
1518 (oid_setprivateoids()). Thanks to RVDM.
1520 Added optional, physical ANY (key replication)
1522 Fixed null-reference problem in GRS-1 output filter.
1524 Proximity operator added to Prefix Query Format (PQF).
1526 In test client command "base" accepts multiple databases.
1528 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1532 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1534 Smallish bug-fixes in the new encoders/decoders (explain).
1536 Bug fixed in DeleteRequest.
1538 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1540 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1542 Added SOIF syntax (using private OID for now) to retrieval module and client.
1544 Added Update extended service.
1546 Added SearchResult-1 additional info structure.
1548 Added optional CCL (ISO8777) interpreter as separate module. Available
1551 --- 1.2 1996/6/10 (1st anniversary release)
1553 Added Summary record syntax. Lightly tested.
1555 Added OPAC record syntax. Untested.
1557 Added ResourceReport service encoders/decoders. Untested.
1559 Fixed bug in z_Unit - wrong tagging on unitSystem.
1561 Fixed bug in the DiagRecs decoder.
1563 Added options for max PDU size and session timeout to frontend-server.
1565 Added documentation of query-language parsers and other supporting utilities.
1567 [frontend-server] Added Attribute set to the bend_scanrequest API.
1569 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1570 surrogate diagnostics were generated.
1572 [retrieval] Allow multiple local values for attribute.
1574 [retrieval] Allow multiple attributes per element in .abs files. index type.
1576 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1578 --- 1.1pl2 1996/4/10
1580 Minor changes, mostly specific to Zebra's requirements (retrieval)
1584 Repaired bug in frontend server when running multiple listening
1585 endpoints in dynamic mode.
1587 z_External() now won't break if a known, ASN.1 value comes encapsulated
1588 in an octet-string. The value will pass through unmodified in an Odr_oct.
1590 Added a bit of code to the demo client to decode & display
1591 ASN.1-structured records represented in the octet-aligned branch of
1592 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1594 Added z_ext_getentbyref() to the ASN module. Doc updated.
1596 * Completed the SCAN definition in the ASN module. This may break SCAN
1597 code based on older YAZ-versions at compile-time. The fix is easy -
1600 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1601 under the SCAN definition. Remember to initialize this, server-people.
1603 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1604 that this does not extend to ODR and ASN.
1606 Comstack allows insertion of established socket (primarily for
1607 inetd-operation of servers). Doc updated.
1609 Front-end server can now start from the inetd in TCP mode. Doc
1612 --- 1.0pl4 1996/1/24
1616 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1617 the rank and record number.
1619 Adjustments to the frontend server.
1621 Fixed diagnostic BER dumper. It ignored the file argument.
1625 Various changes to retrieval module.
1627 Changed the union discriminators of the protocol files from enums to
1628 ints paired with #defines.
1630 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1633 *Changed operator in the RPN structure to 'roperator', again to avoid a
1636 Fixed problems in Explain decoders/encoders.
1638 --- 1.0pl2 1995/12/6
1640 Memory bug in log module fixed.
1642 --- 1.0pl1 1995/12/5
1644 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1646 Bug in Explain DatabaseInfo module fixed.
1648 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1652 The shift to v1.0 signals that we now consider the *core* functionality
1653 of YAZ reasonably stable (the core being more or less equivalent to
1654 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1655 tested (Explain not at all - though that will happen soonish).
1657 Minor changes to code to support Windows port.
1659 Various minor changes after we're getting to use GRS-1 & co. more.
1661 Added Espec-1 format.
1663 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1664 of the protocol and it cannot be selected when encoding (maps into 'string'
1665 when decoding). Needed to talk to some servers.
1667 Demo client can request simple element set names.
1669 Added Diagnostic Format encoders/decoders.
1671 Added simple Close handling to frontend server (no hooks for resource
1672 reporting yet), and demonstration client.
1674 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1676 --- 1.0b3 1995/08/24
1678 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1679 handled incorrectly when records were requested in the searchResponse. This
1680 will only affect you if you use the frontend-server.
1682 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1683 Test-client will ask for and print GRS1. Ztest will return dummy records
1686 Added Explain encoders/decoders to the service-level API. Untested.
1688 Added Extended Services: Item Order encoders and decoders to the Service-
1689 level API. Untested. We could use a recent copy of the pertinent bits
1690 of the ILL protocol to add those bits.
1692 Added diagnostic format 1 encoders/decoders to the service-level API.
1695 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1696 odr_cons.c, which causes a more correct output.
1698 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1699 was always set to 0 when no records were requested in the searchRequest.
1701 * Added better external-handling. This shouldn't harm old code that
1702 *encodes* externals. It can break code that looks for a
1703 'single-ASN1-type' representation, since those types that are known
1704 are now decoded immediately. Look at the SUTRS sample code in
1705 seshigh.c and client.c. Documentation updated.
1707 Handling of structured records in bend_fetchresponse. Length -1 marks
1708 structured record, type is deduced from format field.
1710 --- 1.0b2 1995/06/27
1711 Fairly quick maintenance release to add SUTRS support.
1713 Fixed handling of SUTRS records in the demonstration client.
1715 * Added format field to the bend_fetchrequest and bend_fetchresponce
1716 structures of the backend API (frontend server). When the record is
1717 returned, the value of the format field is mapped to an OID. The
1718 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1719 of the record. The special value VAL_NONE in the bend_request means
1720 that no specific format was requested by the client. Documentation
1721 updated accordingly. Test server (ztest) will return a fixed dummy
1722 SUTRS record if your client requests SUTRS.
1724 Documentation updated accordingly.
1726 You can now set external libraries and RANLIB support in the top-level
1730 First public release.
