3 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
4 GFS to support this as well. Backend handler, bend_srw_update, does the
5 update work. Code contributed by Ko van der Sloot.
7 Allow retrieval of Search Result-1 information in ZOOM by the use of
8 options that are attached to a result set. ZOOM documentation updated
11 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
12 UTF-8 conversion. Patch by Raj Patel.
14 Added option -m to GFS to control formatting of timestamps in log file.
16 Added 'exit' as synonym for 'quit' in yaz-client
18 Added support for specifying SRW resultSetId + resultSetIdleTime in a
19 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
20 for the new members. Patch by Ko van der Sloot.
22 Added support for SRU POST. It is supported for content-type
23 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
25 Do not build the separate Multi-threaded (MT) library libyazthread.la.
26 Instead make the library libyaz.la multi-threaded. Threading as a whole
27 can still be disabled by configure option --disable-threads. Previosly,
28 with older GLIBCs there were problems with MT libs under Apache. This
29 has now been fixed a long time ago.
31 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
34 CQL module modified to be case insensitive for relations/indexes/operations.
36 Fixed bug in CQL transform code: incorrect value relationModifieder
39 Added 'show all' command for yaz-client which retrieves all results
42 Added new yaz-client, xmles, which takes a (private) OID and
43 a document to be sent as an extended service request.
45 Describe new yaz-client commands wait_response and set_auto_wait.
47 Increase TCP/IP listener backlog from 3 (which I am guessing was
48 copied from the SunOS manual entry way back when) so SOMAXCONN, so
49 that the socket will queue as many incoming connections as it's able
50 to handle ongoing connections. In other words, it will never now
51 refuse a connection that it would be able to handle merely because
52 it's not got around to accepting() enough of the pending connections
53 yet. This is the behaviour anyway under Linux, where the listen()
54 argument is ignored; but not under BSD and on systems such as
55 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
56 YAZ-based servers should now be uniform across operating systems in
59 yaz-marcdump uses 64-bit file access on some systems. This is enabled
60 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
61 This allows yaz-marcdump to read large MARC batches (>2 GB).
63 Modified all YAZ source files - except the source which is auto-generated
64 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
67 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
68 corresponding to the existing *_setl() function. These allow option
69 values containing arbitrary valuues.
71 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
72 ZOOM_resultset_sort() in new applications. Its behaviour is identical
73 except that it returns an indicator of whether or not the sort
74 criterion was accepted (0 for OK, -1 for invalid).
78 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
79 MARC output rather than returning "new" buffer.
81 yaz-client warns about unknown init options.
83 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
87 Added support for SRW sort in Generic Frontend Server. Patch
88 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
89 sortKeys - or NULL if none is provided.
91 Fixed bug #307: It was impossible to specify indefinite/no timeout
92 for ZOOM_event. Special timeout value -1 now means indefinite timeout
95 Added support for multiple languages and charsets to be specified in
96 ZOOM. Each charset/language is separated by a blank. If negotiation is
97 in effect in init-response, Option
98 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
99 Code based on patch by Vasiliy Osadchuk.
101 Fixed bug #306: infinite recursion that occurred when calling
102 yaz_log_level_init as the first call (before other log level or
105 Fixed bug in scan handling in front end server: if preferred-Position-In-
106 Response was non-present, a NULL pointer referece was performed.
110 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
111 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
112 now defined for all those error codes. So instead of putting 109 in
113 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
114 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
116 Modified the yaz-marcdump utility to skip garbage bytes between MARC
119 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
121 Program yaz-client now exits and produces an error message if multiple
122 Z39.50 servers are specified on the command line (none or one allowed
125 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
130 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
132 Fixed bug #272: Preserve spacing for CCL terms.
136 Added support for virtual hosts and multiple backend servers for
137 the YAZ frontend server. The configution is XML based and
138 support specificition of CQL to RPN mappings and explain information.
139 See section "Virtual Hosts" in the YAZ manual.
141 Extended OPAC display utility. OPAC display utility renders
142 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
143 to supplement yaz_marc_decode_wrbuf.
145 Fixed a bug in MARC decoder that could caused it to crash for some
146 invalid MARC records. More diagnostics and warnings where added in
147 XML output (warnings, etc are stored in comments).
149 --- 2.0.34 2005/02/08
151 Fixes for UNIX domain sockets. Bug #261.
153 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
155 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
156 Added yaz_marc_subfield_str which defines subfield lead string which is
157 used in YAZ_MARC_LINE format. Default string is blank+$. Added
158 yaz_marc_endline_str which defines end of fields string used in
159 YAZ_MARC_LINE format. Default string is newline.
161 Experimental support for MarcXChange. This format can be produced
162 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
163 http://www.bs.dk/standards/MarcXchange.xsd
165 Added yaz-client commands scansize that sets maximum number of
166 entries to be returned by scan.
168 --- 2.0.32 2005/01/11
170 Added support for SRW scan in yaz-client and Generic Frontend Server.
172 * Added whereInList member to SRW Scan Term.
174 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
176 Fixed NMEM system to return aligned blocks on the smallest boundaries
177 that are suitably aligned for all possible types on the particular
178 architecture YAZ is being built for.
180 --- 2.0.30 2005/01/04
182 Fixed numerious warnings that was issued with newer versions of GCC.
184 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
185 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
188 Make YAZ Generic Frontend Server slightly faster.
190 Enhance (and reduce) logging for Generic Frontend Server.
192 Revert YAZ log system so that it flushes every write operation
193 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
195 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
196 instead of LOG_, due to name clash with syslog(3). LOG_ are still
197 present. New applications should define YAZ_USE_NEW_LOG=1 - this
198 will effectively disable old definitions.
200 --- 2.0.28 2004/11/09
202 Added yaz_log_time_format which specifies log format using
205 Added yaz_log_module_level which returns mask for a module. Value
206 is non-zero mask a if module is enabled; zero if disabled.
208 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
209 in include/yaz/cql.h.
211 Fixed bug #176: Dont throw diagnostics on empty SRU args.
213 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
215 Fixed bug #172: RPM builds does not enable SSL.
217 Doxyfile.in part of dist. Doxyfile generated by configure.
219 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
220 are given and the corresponding component does not exist.
222 Extend CCL documentation in YAZ reference. Describe r=r.
224 --- 2.0.26 2004/10/01
226 Fixed MARC->MARCXML conversion to properly deal with
227 fields, subfields, indicators having non-ASCII characters.
229 Fixed MARC->MARCXML conversion so that ASCII control characters
230 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
233 Added YAZ GFS support for conversion from Z39.50 surrogate
234 diagnostics to SRW surrogate diagnostics.
236 Bug fix: YAZ GFS did not return schema in explainResponse.
238 --- 2.0.25 2004/09/30
240 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
241 now converts recordSchema to elementSetName as well as schema URI.
243 Fixed bug in COMSTACK that prevented HTTP request packages from being
246 --- 2.0.24 2004/09/29
248 Added CCL facility r=r "range" which is similar to r=o "ordered" but
249 does not require white-space before and after the dash in a range, e.g.
250 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
253 Fixed a few AC_TRY_LINK configure tests that did not operate properly
254 due to new GCC removing "redundant" code.
256 Added yaz-client commands scanpos and scanstep that sets preferred
257 position and step-size for scan.
259 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
261 Added CCL utility ccl_qual_buf which parses one or more CCL
262 spec lines in a buffer.
264 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
265 of name and value - ignoring empty lines and comments.
267 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
269 Added odr_get_element_path which returns current element path for an
270 ODR handle. This utility is useful in error handling or user-defined
273 Added ODR_PRINT utility odr_set_stream which is is a more generic
274 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
275 to a write function and pointer to close function. The close function - if
276 non-NULL - will be called during odr_destroy.
278 Fixed bug in CCL parser where truncation char was not removed from
279 right side when truncation=both was in effect.
281 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
284 --- 2.0.23 2004/08/11
286 Fix buffer overrun in CQL parser when dealing with proximity (%).
288 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
289 to UTF-8/UCS conversion is now only based on codetables.xml.
291 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
293 --- 2.0.22 2004/08/06
295 Add support for more "commit changes" in ZOOM (uses Extended Services).
297 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
300 Yet another small fix for configure of SSL.
302 --- 2.0.21 2004/05/14
304 Fix SSL libs for configure when --with-openssl=DIR is given.
306 --- 2.0.20 2004/05/10
308 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
310 SSL comstack now uses yaz.pem certificate file on server side
311 by default. Certificate filename can be configured by calling
312 comstack function cs_set_ssl_certificate_file before cs_bind is used.
314 Fix bug regarding multiple calls to ZOOM_connection_connect.
316 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
318 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
319 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
321 ZOOM now allows inspection of X509 peer certificate for verification.
322 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
324 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
325 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
326 as "modular" but it simplifies things.
328 Added cs_get_peer_certificate to that returns peer X509 PEM.
330 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
331 NULL if SSL is unavailable.
333 Documentation about MARC decoding tools.
335 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
337 --- 2.0.19 2004/03/30
339 Rename CHANGELOG to NEWS to follow GNU style packing.
341 Fix bug with missing initialization of member in init_diagnostics.
342 This bug affects threaded version of GFS server.
344 --- 2.0.18 2004/03/20
346 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
349 Ensure zlib.dll is packed with Windows install.
351 --- 2.0.17 2004/03/17
353 Fix encoding of xsd:string to use text instead of CDATA.
355 Fix endless loop in CQL parser with unbalanced ".
357 Use a more compact way to store MARC-8 conversion tables.
359 --- 2.0.16 2004/03/16 Debian only
361 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
364 Update CQL parser to use new CQL 1.1 modifiers for booleans and
369 --- 2.0.15 2004/03/01
371 Another fix for decoding of XML packed records.
373 --- 2.0.14 2004/02/25
375 Fixes for Chunked encoding. White space not ignored after length spec.
377 Update NS and use default NS for SRW diagnostic elements.
379 --- 2.0.13 2004/02/23
381 Implement ZOOM_resultset_cache_reset which resets record cache.
383 Implement ZOOM_resultset_sort which sorts a result set.
385 Implement chunked HTTP transfer.
387 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
389 --- 2.0.12 2004/02/16
391 Added member 'schema' to bend_explain_rr structure so that backend
392 can specify explain record identifier. Defaults to Zeerex 2.0.
394 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
396 --- 2.0.11 2004/02/16
398 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
401 Added init command for yaz-client which sends "extra" init request.
403 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
404 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
406 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
408 Make ZOOM error code for "invalid query".
410 Fixed compilation for SSL which wasn't properly enabled for all platforms.
412 --- 2.0.10 2004/02/05
414 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
417 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
419 Added option -p <file> to make Generic Frontend Server to write PID file.
421 Added option -D to put Generic Frontend Server in background on its own.
423 Make ZOOM C recognize option "password". If unset, "pass" is used
424 (for backwards compatibility).
426 Fixed a bug in Generic Frontend Server that could make it crash if a
427 client sets characterSetNegotation bit, but didn't pass negotiation stuff
430 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
431 Must be issued before open, in order to be in effect.
433 --- 2.0.9-6 2004/01/12 Debian/Windows
435 Make the SRU server more picky WRT unknown params, etc.
437 Bug fix: ZOOM scan response didn't return displayTerm - when present.
439 New YAZ client command, options, that sets Z39.50 options.
441 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
442 options from a string of tokens (one token for each option bit).
444 Update SRW diagnostic code messages.
446 --- 2.0.9-5 2004/01/07 Debian/Windows
448 Handle user defined stylesheet for SRW/SRU.
450 --- 2.0.9-4 2004/01/06 Debian/Windows
452 Fix bug in decoding of Content-Length.
454 --- 2.0.9-3 2004/01/06 Debian/Windows
456 Fix a bug with decoding of XML packed records.
458 --- 2.0.9-2 2004/01/05 Debian only
460 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
462 Fix bug in SRW/SRU diagnostics decoding.
466 Fixed bug in Generic Frontend Server which could drop records exceeding
467 preferred message size. Reported and fixed by Irina Dijour.
469 Fixed calculation of package size for structured records in Generic
470 Frontend Server. Reported and fixed by Irina Dijour.
472 Fixed namespace for SRW/SRU diagnostics.
474 Fixed SEGV in yaz-client that occured for HTTP connection errors.
478 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
479 this version is incompatible with version 1.0 and older YAZ SRW/SRU
482 CQL changes to reflect recent changes to the specification:
483 * Documentation talks about context sets instead of index sets.
484 * Documentation talks about indexes instead of qualifiers.
485 * The CQL-to-PQF transformer's configuration file now uses
486 "index.set.name = <attributes>" instead of the old form
487 "qualifier.set.name = <attributes>". (Both forms are still
488 understood but the latter is deprecated.)
489 * CQL terms with no explicit index specified are now interpreted as
490 cql.serverChoice instead of srw.serverChoice (which of course
491 behaves exactly the same.)
495 MARC conversion can now generate ISO2709 output in another
496 character set. yaz-marcdump uses this facility if you invoke it
499 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
500 functions from there can be used from C++.
504 Frontend server now transfers memory from decoded packages to stream
507 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
508 references to show up.
510 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
511 the ZOOM Abstract API. The older names for the same options are still
512 also supported for the benefit of old applications.
514 ZOOM-C supports "implementationId" and "implementationVersion" options
515 to go along with "implementationName". These allow the user code to
516 specify identification strings to be sent to servers.
517 Add OID for the new ExtLite attribute set.
519 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
520 as requested/supplid by Ere Maijala <ere@atp.fi>
522 For generic frontend server, reverse the order of
523 "toolkit-supplied / application-supplied" strings sent as implementationId,
524 Name and Version. Also, remove the spaces around the slash. This brings
525 the GFS in line with the behaviour of ZOOM-C on the client side.
527 Add function ZOOM_scanset_display_term.
529 yaz-client shows scan displayTerm if present.
531 Utility yaz-iconv is now installed by default along with the man page
534 Extend configure check for OpenSSL to use pkg-config where available (such
537 Incorporate patch by Morten Bogeskov which allows a Unix file socket
538 server to specify uid/gid/mask for socket using the format
539 unix:[user=uid,][group=gid,][umask=mask,]file=path
540 If file= is omitted the existing format is assumed, e.g.
542 in which case the mask is 0666 (rw for everybody).
544 Major restructure of YAZ source. All source in libyaz is in src directory.
545 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
546 util (utility programs such as ASN.1 compiler, yaz-marcdump).
548 Added man page for utility yaz-marcdump (used to be called marcdump).
549 yaz-marcdump is installed by 'make install'.
551 Fixed a memory leak in Generic Frontend Server that occurred when decoding
552 of incoming package failed.
554 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
556 Change prototype of odr_perror: add const to message string.
558 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
560 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
561 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
562 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
563 DNS lookup. There should not be any compatibility problems with this
564 assuming that blocking=1 or 0 is used.
566 Fix bad reference in UNIX comstack in function cs_addrstr.
568 Fix for compilation on AIX.
570 The generic front-end server (server/seshigh.c) now supports returning
571 Init diagnostics to the client in User-information-field, in
572 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
577 Allow any CQL relation (not just all,any,exact,scr).
579 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
580 that features the same UI.
582 Implemented command update0 in YAZ client which is equivalent to
583 update but uses old of Ext Update ASN.1.
585 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
586 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
587 Previously no OID was used for this info.
589 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
590 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
591 returns 'malformed search term' otherwise.
593 SortResponse member resultCount now set to NULL in sort handler of
596 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
599 Add three new utility functions for translating OIDs between various
600 formats -- symbolic name such as "Usmarc", minus-1-terminated int
601 arrays and dotted strings such as "1.2.840.10003.9.5.1":
602 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
603 char *oid_to_dotstring(const int *oid, char *oidbuf);
604 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
606 Reverted modifications for ES Update definition for z_IU0Update
607 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
608 is back to YAZ 2.0.2.
610 String value attributes for CCL parser.
612 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
613 which their FirstSearch server returns in Init responses, sometimes
614 carrying useful diagnostic information when Init fails. This has the
615 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
616 "z39.50/oclcui.asn", where its definition is somewhat different from
617 what OCLC document on their web-site, as required to interoperate with
620 Support for anonymous authentication in yaz-client. Use the command
623 * Fix the OID of the Index Data-local "admin" Extended Service from
624 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
625 the 1000, which indicates a locally-defined OID, was a mistake.
629 Fix CCL directive @case handling so that it affects string match for
630 both CCL keywords and qualifiers.
632 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
633 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
634 Decoder has been updated with ASN.1 changes as listed in
635 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
636 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
637 z_IUUpdate, remains unchanged.
639 ZOOM_record_get may now return a record in a specific character set.
640 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
641 "from" is the character set of record as returned by target. "to" is
642 the character set to be returned. If omitted, "to" is UTF-8.
644 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
646 New ODR utility, odr_getelement, which returns name of element for
647 which encoding/decoding failed.
649 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
650 in cases where a required element was omitted.
652 Bug fix: some MARC8 sequences were not converted.
654 New ZOOM option "step" which specifies number of records to be
655 retrieved in one chunk. Used in conjunction with "start" and "count".
657 SRW support for yaz-client. Use scheme http: to use it, e.g.
660 yaz-client no longer does (un)intelligent character set conversions
661 by default. Can be enabled with charset and marc_charset commands.
663 xmalloc trace fix for 64-bit systems such as DEC alpha.
665 Solaris 2.6 compile fix.
667 New function, cql_strerror() translates SRW error codes, as returned
668 by cql_transform_error(), into human-readable English strings. Used
669 in yaz-client diagnostics when appropriate.
671 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
672 converts it into a type-1 query which is sent to the server. This
673 makes CQL available for use with all Z-servers, as opposed to the tiny
674 minority that can handle CQL queries themselves.
678 New Debian package layout similar to the Redhat Package layout.
680 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
681 and search result respectively.
685 Redhat package is now several packages: libyaz (runtime libraries),
686 libyaz-devel (development and documentation, and yaz (utility programs).
687 Package spec file by Morten Bøgeskov.
689 New member 'schema' in struct bend_fetch_rr which the name of requested
690 schema (SRW/SRU) for record (or NULL if none was given). The fetch
691 handler MAY set this to reflect the schema of the returned record.
693 New member 'display_term' in struct scan_entry. GFS now sets member entries
694 and allocates scan entries to be filled by user scan handler. In previous
695 version, entries member was allocated by the scan handler. That still works,
696 but the GFS will ignore member display_term - assuming it was NOT set by
697 the handler. The fact that the GFS now allocates the entries both allows
698 for new members and makes a scan handler easier to write.
700 Fix CQL lex buffer overflow.
702 SRW/SRU recordPacking. For SRW default recordPacking is string. For
703 SRU default recordPacking is string.
705 SRU protocol support for frontend server.
707 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
709 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
711 Added scan for the ZOOM shell (zoomsh).
715 * String Identifers for Schemas (Amendment 5).
716 http://lcweb.loc.gov/z3950/agency/amend/am5.html
717 Old definition for schema
718 Odr_oid *schema; /* OPT */
723 Z_InternationalString *uri;
724 #define Z_Schema_oid 1
725 #define Z_Schema_uri 2
728 * resultCount parameter to Sort Response (Amendment 1).
729 http://lcweb.loc.gov/z3950/agency/amend/am1.html
731 Support for SRW 1.0 over HTTP. This is an optional feature and
732 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
735 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
736 on the same port. SRW SearchRetrieveRequests are mapped
737 to bend_init,bend_search,bend_fetch,bend_close.
739 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
741 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
742 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
744 ZOOM connections are SRW based if schem http is used for hostname
745 in connect, e.g. z = ZOOM_connection_new("http://myserver");
746 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
748 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
749 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
750 distance=n, order=true/false, relation=le, prox unit=word. If
751 n is omitted, distance 1 is used.
753 Fixed problem with C compiler include path in wrong order.
755 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
756 on Solaris. Patch from Ko van der Sloot.
758 New MARC decode API. All new functions operate on a yaz_marc_t
759 handle. The most important new functions are: yaz_marc_create,
760 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
761 decode and destroy respectively. Decoder can produce formats
762 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
763 include/yaz/marcdisp.h.
765 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
766 to UTF-8, UCS-32, wchar_t or Latin-1.
768 * Prototypes for yaz_iconv_-functions moved to separate header
769 include/yaz/yaz-iconv.h.
771 Make a few private functions 'static' in unix.c. This prevents
772 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
774 For ZOOM connection, the options targetImplementation{Id,Name,Version}
775 are set when Init Response is received.
777 New function ZOOM_connection_error_x similar to ZOOM_connection_error
778 but returns diagnostic set as well.
780 New function yaz_strerror which is a portable wrapper for
781 strerror/strerror_r/GetLastMessage.
783 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
784 is returned for MARC. If type is "oai", then OAI MARC is returned.
786 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
791 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
793 Fix bad race conditions on SIGTERM and terminate gracefully in
796 Move retrieval (data1) module to Zebra since nobody seems to be
799 Add GRS-1 render for ZOOM using same format as yaz-client.
803 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
805 Fix broken ESpec handling in data1 module.
807 SGML reader parses comments and makes them part of the data1 tree.
809 Added several type casts so that YAZ compiles as C++ code.
811 ZOOM didn't handle PDU encoding failures properly.
813 Added more Bib-1 diagnostics (approved extensions).
815 GNU configure: better check for iconv.
817 More portable use of accept, getpeername. Check for socklen_t. Use
818 int/size_t if socklen_t is not defined.
822 PQF parser rejects bad queries - including those with extra
823 characters in them. PQF parser used to silently ignore that.
824 Cleaner API for PQF added, which allows you to get detailed
825 error information for bad queries (see yaz/pquery.h).
827 Fixed bug in ZOOM_record_get for type "database".
829 Implemented mini iconv library supporting conversions between
830 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
832 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
836 Fixed ZOOM C record cache so that preferredRecordSyntax and
837 elementSetName is used to check for already fetched records.
841 Added three members in bend_initrequest structure to facilitate
842 character set negotiation.
844 Fixed a bug in frontend server that could cause indefinite
845 loops under rare conditions.
847 Revised character set utilities (charneg.h) so that encoding
848 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
850 For PQF, directive @term <type> sets term type for Scan/Search.
851 Here <type> is general, string, numeric, null. The term type
852 is inherited - just like @attr.
854 New call odr_set_charset that sets character set conversion for
855 international-strings on a ODR stream. Prototype is:
856 int odr_set_charset(ODR o, const char *to, const char *from);
857 The InternationalString is still represented as C string in YAZ
858 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
859 won't). On the protocol level, you can use any encoding.
861 Support for UNIX sockets in ZOOM.
863 Solaris recv sometimes returns errno == ENOENT. It is treated as
864 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
866 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
867 both client and server. Code by Morten Bøgeskov.
871 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
872 that they can be used directly from Visual Basic. You must recompile
873 your windows APP if you're using ZOOM.
875 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
876 Commands "lang" and "charset" sets language and character set respectively.
877 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
878 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
880 Attributes from multiple CCL fields may be OR'ed rather than merged
881 using directive "@field or". Fields are still merged by default -
882 equivalent to "@field merge".
884 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
887 Fixed bug in zget for parameter ExtendedServicesResponse.
893 Added PQF feature: '@attr type=value' may be written as '@type=value'.
895 Client displays USR.1:SearchResult-1 (hits per term).
897 Additional Search Info for search in Generic Frontend Server.
899 Fixed CCL parsing of "field=s".
901 WIN32 installer - using the excellent NSIS software from nullsoft.
903 Fixed CCL parsing of "field = - <number>".
905 Added function yaz_marc_decode that decodes MARC for line mode
906 display or XML (similar to that used by JZKit).
908 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
909 Z39.50. But ISO/ILL was, however.
911 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
912 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
914 http://lcweb.loc.gov/z3950/agency/amend/am2.html
915 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
919 New YAZ client features: Command completion and new commands:
920 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
921 Code provided by Jacob Poulsen.
923 New call oid_trav, that visits all registered OIDs via callback.
925 Function ZOOM_record_get now returns const char pointer rather than
926 void pointer. It saves a lot of type casts.
928 For YAZ client, command "auth" now allows you to set authentication
929 in IdPass style. It is enabled when three tokens are given - order
930 is user, group and password.
932 Fix memory leaks in MARC record handling for ZOOM.
934 New option for YAZ client, -k <kilobytes> that sets
935 maximum record size. Similar to -k option for generic frontend
936 server and yaz-ztest.
938 More fixes for scan. Non-zero stepSize handled. OID's fixes.
940 Prefix query parser reports "fail" when bad attribute set is given.
942 Fix in MARC decoder. Proximity logging. Fix for attribute set
943 in scan handler for server. Patches by Shigeru Ishida.
945 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
948 Configure option --with-openssl=<dir> now works when a directory is
949 specified. Patch provided by Morten Bøgeskov.
951 New option for YAZ client, -u <auth>, that sets authentication.
953 ZOOM fix: error information was sometimes "missing", since error
954 was cleared/reset too when it shouldn't.
956 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
960 Scan for ZOOM API. New object ZOOM_scanset. New functions
961 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
962 ZOOM_scanset_destroy.
964 New ZOOM function, ZOOM_connection_last_event, that returns type
965 of last event (such as "receive data", "send data", "apdu received",
968 New ZOOM option, schema, that specifies schema for retrieval.
970 New CCL feature. Qualifiers can be aliases for one or more
971 other qualifiers (if more than one is given, OR is used).
973 ZOOM uses named result sets if target supports it.
975 Two new YAZ client commands: . (dot, which sources a script of YAZ
976 client commands), and ! (to execute shell command.). Implemented
979 Working on Debian packages.
983 YAZ client enables named result sets only if target supports it.
985 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
987 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
988 with key="host" to get same result.
990 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
991 Function Z3950_resultset_record(s) returns references to records
992 "owned" by resultset. To become owner use Z3950_record_clone.
994 Function z_ext_record handles Extended Services. Thanks to
999 CCL Parser fix: ignore token comma when dealing with and-lists.
1001 Documentation updates for COMSTACK.
1003 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1004 Changed prototype Z3950_records. For some functions, int parameters
1005 were changed to size_t.
1007 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1010 New MARC decode/display function, marc_display_exl, which properly rejects
1011 non-ISO2709 records. YAZ client uses it.
1013 --- 1.8.1 2001/10/29
1015 Fix bug: local attribute set wasn't set correctly in PQF strings.
1019 * Old Z39.50 codecs no longer supported.
1021 Added ZOOM C binding. See http://zoom.z3950.org/
1023 Renamed states for COMSTACKs to avoid confusion with events.
1025 Implemented cs_look and proper cs_rcvconnect.
1027 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1029 Configure detects POSIX threads on OpenBSD.
1031 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1032 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1034 When error is returned from present handler, non-surrogate diagnostic
1035 is returned in present response (and fetch handler is no longer called).
1037 * Minor adjustments to pquery parser (PQF). Token characters may be
1038 escaped by using backslash (C-style).
1040 PQF parser allows string attribute values to be specified. For @attr,
1041 non-numeric characters after the equal-sign are treated as strings
1042 (e.g. @attr 9=title).
1044 CCL trunction character may be defined (@truncation in file)
1046 * function zget_ExtendedServicesRequest sets waitAction to
1047 waitIfPossible (was wait).
1049 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1052 CCL operator names may be set in field definition files (CCL_bibset).
1053 See ccl/bib1 for an example.
1055 Fixes in ASN.1 compiler for C++ compatibility.
1057 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1058 and "op_or" to avoid conflict with C++.
1060 Fixed problem with GNU readline detection on Redhat 7.0.
1062 Added step-size for Scan backend handler.
1064 Fixed bug that made the frontend server crash when no attribute
1065 set was specified for scan.
1067 Front-end server automatically switches to original working directory
1068 when installed as an NT service. Previously -w had to be specified to
1071 Added extended attributes for retrieval module (data1), so that data1
1072 records carry d1_readXML/SGML attributes. d1_read also supports
1073 null-data rules ( <tag/>)
1075 On UNIX when POSIX threads are available, a separate library libyazthread
1076 is created. Programmers should link with that library and the yaz library
1077 when using threads. The reason for the split was that some applications
1078 on Linux, such as Apache, doesn't work well when using shared objects that
1081 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1082 (or any frontend server) in SSL mode by specifying ssl: followed by
1083 address. Only tested on UNIX.
1085 Added feature for CCL module. Virtual structure s=al or s=ol generates
1086 and-list and or-list respectively instead of phrase search.
1090 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1091 log_mask_str. This was done to avoid name conflicts with other libraries
1092 (such as other PHP extensions).
1094 Added raw OID member for preferred record syntax (request_format_raw)
1095 and returned record syntax (output_format_raw) for backend fetch method.
1097 Config file yaz-config now accepts options so that it returns specific
1098 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1100 Shared library support for UNIX using GNU libtool.
1102 * Modified backend interface. Request/Response struct's replaced by
1103 one read/write C struct. For example bend_fetchrequest and
1104 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1105 Every handler - even search has to be registered in bend_init
1106 handler. This means that the YAZ library no longer refers to
1107 external functions and it makes it possible to make the whole
1108 thing a single DLL/SO.
1110 Added Segment handler for backend server.
1112 Added Zmbol/Zebra administrative functions to YAZ client.
1114 Threaded frontend server on UNIX (when POSIX Threads are available).
1115 Starting the server with option -T enables multi-threading.
1119 Added configure option --enable-comp/disable-comp to control use
1120 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1121 located in sub directory asn.
1123 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1124 in ${exec_prefix}/bin along with the other programs yaz-client and
1127 GNU automake used to maintain makefiles.
1129 Added several OID's.
1131 Changed retrieval module so that we can load records with no abstract
1132 syntax defined. Tagpaths in these records are fully composed of string
1135 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1139 On UNIX, the generated makefile now supports a proper 'make install'.
1140 The prefix can be set via GNU configure to set the install location
1141 (default is /usr/local).
1143 * YAZ programs client and ztest were renamed to yaz-client and
1144 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1145 locations, such as /usr/bin,/usr/local/bin,etc.
1147 * YAZ Header files were moved from include to include/yaz. YAZ Header
1148 files are referred to as include <yaz/log.h> rather than <log.h>.
1149 The YAZ include path (-I ..) is therefore the same as before. Programmers
1150 should update their #include statements or use -Ipath/include/yaz
1151 instead. The main motivation for doing this change is that YAZ header files
1152 can be installed in "standard" locations /usr/include,/usr/local/include
1153 without introducing conflicts, since ALL YAZ header files are stored
1154 in subdirectory yaz (under /usr/include for example).
1156 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1157 rather than project/workspace files. We switched because project files
1158 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1161 Changed name of logging function, logf, to yaz_log, to prevent name
1162 clash with some math-log functions. The YAZ header log.h defines logf
1163 to yaz_log (#define) so there should be no incompatibilities by this
1166 Added bend_start/bend_stop handlers for server. These handler are
1167 called on start/stop of server. For windows they are called whenever
1168 a service is started/stopped.
1170 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1171 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1172 in util/yc.tcl. The auto-generated C code structures are, in a few
1173 cases, incompatible with the old decoders. There are differences in the
1174 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1175 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1176 The preprocessor variable ASN_COMPILED is defined when the compiled
1177 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1178 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1179 wish to use the old encoders/decoders you can specify --disable-yc
1182 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1183 version so that it supports both new - and old version of DB Update
1185 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1186 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1187 change. The name parameter can be set to 0 in which no name is specified
1188 for the construction. The macros odr_implicit and odr_explicit sets name
1189 parameter to zero for the construction involved. New macros
1190 odr_implicit_tag and odr_explicit_tag are similar to the others,
1191 except that a name parameter is added. For programmers' that don't use
1192 ODR they probably only need to change the call to z_APDU and z_External.
1194 Added access control facility by interfacing the TCP wrapper library.
1195 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1196 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1197 name of the daemon and enables the access control as specified in
1198 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1200 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1201 den Dool <H.M.vdnDool@kub.nl>.
1203 Added reference ID parameter to most functions in server API - refer
1204 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1206 Changed name of ccl library to libccl.a (was ccl.a).
1208 Fixed bug in decoder for Explain (Category TargetInfo).
1210 Added support for GNU readline in client. Thanks to Jacob Poulsen
1211 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1213 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1214 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1215 IMPLEMENTATION! This change was made to the development version before
1216 the ZIG decided to retract the amendment. If any users MUST be
1217 compatible with the original Update definition, PLEASE CONTACT US, and
1218 we will include a separate definition corresponding to the old Update
1219 ES. Note that because of the change to the ASN.1 of the
1220 TaskPackageRecordStructure we cannot define a single structure that
1221 will support both versions.
1223 * Added const modifier to buffer parameter for some ODR/BER encoding
1224 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1225 completeWAIS, odr_dumpBER.
1227 Fixed bug in client.c which caused a crash when a scanResponse didn't
1228 contain positionOfTerm.
1230 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1231 * will cause an error in a client if a non-YAZ target sends both a
1232 * list of Scan entries and non-surrogate diagnostics.
1234 Retrieval module enhancements. Tag sets may be typed in the reference
1235 to it. From the .abs-file the "tagset" directive takes a third optional
1236 integer type for the tag set referenced. From a .tag-file the "include"
1237 directive takes a third optional type as well. The old "type" directive
1238 in the tag set itself is still recognized but acts as the default type
1241 Backend interface change. Individual Scan terms returned from bend_scan
1242 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1243 in include/backend.h.
1245 Retrieval module enhancements. Multiple tag sets and attribute sets may
1246 be specified in abstract syntax specs. Revised the error/warning for
1247 logging messages reported by the retrieval module when reading the
1250 Object Identifier system (oid_..) changed. The API is backwards
1251 compatible but the oid-routines now allocates new OID's when needed.
1252 Raw OID's may be specified in oid_getvalbyname.
1254 YAZ now uses GNU configure to generate Makefile(s).
1256 * Minor changes in some of the member names of DeleteResultSetRequest and
1257 DeleteResultSetResponse. See include/proto.h.
1259 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1260 and added member 'languages' in TargetInfo (which was missing).
1262 Changed the way attribute sets are handled in the retrieval
1263 module. These are now cached, just like the abstract syntaxes
1266 Changed YAZ so that it links with compiled ASN.1.
1268 Added Explain-schema definitions and mapping routines. The following
1269 Explain categories have been implemented: AttributeDetails,
1270 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1272 Fixed minor bug in Windows version of Server Library.
1274 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1276 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1278 Added EXTERNAL: UNIverse Resource Report (non-standard).
1280 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1281 ENUMERATED and SET OF.
1283 * Added 'const' to some of the char pointer arguments for the
1284 functions, data1_read_node, data1_getelementbytagname,
1285 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1288 Fixed bug in data1_insert_taggeddata - the last_child member of
1289 parent wasn't initialised.
1291 * Changed data1_read_record and data1_read_node so that the supplied
1292 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1293 doesn't refer to any parts of the "SGML"-buffer.
1295 Fixed bug in server library (Windows version of statserv_remove).
1297 * Changed code so that it compiles as C++. The type definition
1298 of Odr_fun which is a member of Odr_arm was changed. The result is,
1299 that an explicit typecast is needed for the fun pointer when
1300 using Odr_arm - as in:
1301 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1303 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1305 Implemented the new structured date and time definition as approved
1306 by the ZIG. Added schemaId element to the specificTag in Espec-1
1307 (also approved at the last ZIG). Thanks to RVDM.
1309 Added some Object identifiers (RVDM).
1311 Changed the Update Extended Service (RVDM).
1313 Added command "refid" to client which specifies referenceId for
1314 the following requests.
1316 Implemented extended service handling for server. See ztest.c
1317 for an example as well as backend.h. New handlers are registerd
1318 in the Init handler.
1320 * Changed interface for sort in server.
1322 Added new members to statserv_options_block. It allows a server
1323 to read options from another source than just the command line. Thanks
1324 to Charles Woodfield.
1326 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1327 renamed to zboolean. Some C++ compilers complained about the name.
1329 Minor changes to gils.abs. Added index 's' (sort) on title
1330 and date/time-last-modified.
1332 --- 1.4pl2 1998/1/30
1334 Fixed bug in server library regarding inetd mode (-i). This bug
1335 was introduced by release 1.4.
1337 --- 1.4pl1 1998/1/29
1339 Added sort facility in client and backend server interface.
1341 Fixed problem with dependencies in Makefile(s).
1343 Fixed bugs for encoders/decoders of extended services and
1346 Implemented sub-tree feature for schemas. Sub-trees are
1347 referenced in *.abs-files. See explain.abs for an example
1348 of the use of this feature.
1350 Modified bib1.att; local attributes for ANY didn't include
1351 ANY itself (only affects use of the retrieval module).
1353 Fixed bug in plain SGML reader in function data1_read_node:
1354 tags with prefix "var" was incorrectly interpreted as variants.
1356 Added feature "sub-schemas" to enable references to - and definitions
1357 of - group of elements.
1359 * Removed member parent from type data1_element (in data1.h).
1361 Implemented function odr_nullval() that returns the value of
1364 * Removed member num_children from data1_node (in data1.h).
1366 Made NT service interface part of the server library. The
1367 function statserv_main uses the NT service when required and
1368 calls the statserv_start / statserv_close routines.
1370 Routine zget_SearchRequest and zget_PresentRequest fills
1371 resultSetName/Id member with "default" instead of "Default".
1373 Fixed memory leak in server. Request queue member wasn't freed.
1375 Fixed nmem_exit so that memory is freed.
1379 Revised the CCL parser utility to be thread safe.
1381 Added function, oid_ent_to_oid, to replace the function
1382 oid_getoidbyent, which is not thread safe.
1384 * Added nmem_init and nmem_exit to initialize and release
1385 NMEM resources. Function nmem_init should be called once in the
1386 initial thread before NMEM/ODR is used. statserv.c and client.c
1387 have been changed accordingly. The change was necessary to make
1388 NMEM thread safe. The NMEM memory pool is shared amongst threads
1389 in a process. Unix-based applications will still work fine without
1392 Added NT Services interface for the the Z39.50 (statserv) Server.
1393 Refer to the ztest.c source on the usage.
1395 Windows 95/NT port using MSVC5.0. Project files are included in the
1398 * Defined new 'global' handle for the retrieval (data1) system. The
1399 new handled, data1_handle, describes the state of the data1 system.
1400 This handle is passed as first argument to virtually all
1401 data1 related routines. The functions data1_create and data1_destroy
1402 creates and destroys a data1 handle respectively.
1404 Added ODR encode stream member to all backend request structures
1405 init, search, scan etc. This stream should be used to allocate all
1406 memory used for the response when thread safe operation is needed.
1408 Changed the comstack utility, cs_addstr, to be thread safe. The
1409 returned hostname string returned by the function is now part the
1412 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1413 function. The cs_straddr takes a COMSTACK handle as argument, so this
1414 function must be used after cs_create and before bind/connect.
1415 This function is thread safe.
1417 Moved test server to 'ztest' directory - generic server code still
1418 in 'server' directory.
1420 Made prefix query (pquery.c) utility thread safe.
1422 Added new function modifier YAZ_EXPORT to 'export' public DLL
1423 functions when using windows (see include/yconfig.h).
1425 Added definitions to the OID database (util/oid.c) (RVDM).
1427 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1429 Added call to ccl_rpn_delete in client program.
1431 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1432 release of RPN structure.
1434 Added support for C++, headers uses extern "C" for public definitions.
1435 With input from RVDM.
1437 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1438 Thanks to Ronald van der Meer (RVDM).
1440 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1442 Added support for private extensions to the OID database
1443 (oid_setprivateoids()). Thanks to RVDM.
1445 Added optional, physical ANY (key replication)
1447 Fixed null-reference problem in GRS-1 output filter.
1449 Proximity operator added to Prefix Query Format (PQF).
1451 In test client command "base" accepts multiple databases.
1453 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1457 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1459 Smallish bug-fixes in the new encoders/decoders (explain).
1461 Bug fixed in DeleteRequest.
1463 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1465 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1467 Added SOIF syntax (using private OID for now) to retrieval module and client.
1469 Added Update extended service.
1471 Added SearchResult-1 additional info structure.
1473 Added optional CCL (ISO8777) interpreter as separate module. Available
1476 --- 1.2 1996/6/10 (1st anniversary release)
1478 Added Summary record syntax. Lightly tested.
1480 Added OPAC record syntax. Untested.
1482 Added ResourceReport service encoders/decoders. Untested.
1484 Fixed bug in z_Unit - wrong tagging on unitSystem.
1486 Fixed bug in the DiagRecs decoder.
1488 Added options for max PDU size and session timeout to frontend-server.
1490 Added documentation of query-language parsers and other supporting utilities.
1492 [frontend-server] Added Attribute set to the bend_scanrequest API.
1494 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1495 surrogate diagnostics were generated.
1497 [retrieval] Allow multiple local values for attribute.
1499 [retrieval] Allow multiple attributes per element in .abs files. index type.
1501 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1503 --- 1.1pl2 1996/4/10
1505 Minor changes, mostly specific to Zebra's requirements (retrieval)
1509 Repaired bug in frontend server when running multiple listening
1510 endpoints in dynamic mode.
1512 z_External() now won't break if a known, ASN.1 value comes encapsulated
1513 in an octet-string. The value will pass through unmodified in an Odr_oct.
1515 Added a bit of code to the demo client to decode & display
1516 ASN.1-structured records represented in the octet-aligned branch of
1517 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1519 Added z_ext_getentbyref() to the ASN module. Doc updated.
1521 * Completed the SCAN definition in the ASN module. This may break SCAN
1522 code based on older YAZ-versions at compile-time. The fix is easy -
1525 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1526 under the SCAN definition. Remember to initialize this, server-people.
1528 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1529 that this does not extend to ODR and ASN.
1531 Comstack allows insertion of established socket (primarily for
1532 inetd-operation of servers). Doc updated.
1534 Front-end server can now start from the inetd in TCP mode. Doc
1537 --- 1.0pl4 1996/1/24
1541 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1542 the rank and record number.
1544 Adjustments to the frontend server.
1546 Fixed diagnostic BER dumper. It ignored the file argument.
1550 Various changes to retrieval module.
1552 Changed the union discriminators of the protocol files from enums to
1553 ints paired with #defines.
1555 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1558 *Changed operator in the RPN structure to 'roperator', again to avoid a
1561 Fixed problems in Explain decoders/encoders.
1563 --- 1.0pl2 1995/12/6
1565 Memory bug in log module fixed.
1567 --- 1.0pl1 1995/12/5
1569 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1571 Bug in Explain DatabaseInfo module fixed.
1573 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1577 The shift to v1.0 signals that we now consider the *core* functionality
1578 of YAZ reasonably stable (the core being more or less equivalent to
1579 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1580 tested (Explain not at all - though that will happen soonish).
1582 Minor changes to code to support Windows port.
1584 Various minor changes after we're getting to use GRS-1 & co. more.
1586 Added Espec-1 format.
1588 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1589 of the protocol and it cannot be selected when encoding (maps into 'string'
1590 when decoding). Needed to talk to some servers.
1592 Demo client can request simple element set names.
1594 Added Diagnostic Format encoders/decoders.
1596 Added simple Close handling to frontend server (no hooks for resource
1597 reporting yet), and demonstration client.
1599 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1601 --- 1.0b3 1995/08/24
1603 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1604 handled incorrectly when records were requested in the searchResponse. This
1605 will only affect you if you use the frontend-server.
1607 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1608 Test-client will ask for and print GRS1. Ztest will return dummy records
1611 Added Explain encoders/decoders to the service-level API. Untested.
1613 Added Extended Services: Item Order encoders and decoders to the Service-
1614 level API. Untested. We could use a recent copy of the pertinent bits
1615 of the ILL protocol to add those bits.
1617 Added diagnostic format 1 encoders/decoders to the service-level API.
1620 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1621 odr_cons.c, which causes a more correct output.
1623 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1624 was always set to 0 when no records were requested in the searchRequest.
1626 * Added better external-handling. This shouldn't harm old code that
1627 *encodes* externals. It can break code that looks for a
1628 'single-ASN1-type' representation, since those types that are known
1629 are now decoded immediately. Look at the SUTRS sample code in
1630 seshigh.c and client.c. Documentation updated.
1632 Handling of structured records in bend_fetchresponse. Length -1 marks
1633 structured record, type is deduced from format field.
1635 --- 1.0b2 1995/06/27
1636 Fairly quick maintenance release to add SUTRS support.
1638 Fixed handling of SUTRS records in the demonstration client.
1640 * Added format field to the bend_fetchrequest and bend_fetchresponce
1641 structures of the backend API (frontend server). When the record is
1642 returned, the value of the format field is mapped to an OID. The
1643 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1644 of the record. The special value VAL_NONE in the bend_request means
1645 that no specific format was requested by the client. Documentation
1646 updated accordingly. Test server (ztest) will return a fixed dummy
1647 SUTRS record if your client requests SUTRS.
1649 Documentation updated accordingly.
1651 You can now set external libraries and RANLIB support in the top-level
1655 First public release.
