1 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2 GFS to support this as well. Backend handler, bend_srw_update, does the
3 update work. Code contributed by Ko van der Sloot.
5 Allow retrieval of Search Result-1 information in ZOOM by the
6 use of options that are attached to a result set. ZOOM documentation
9 Fixed bug #416: First/second comb characters not handled in the
10 MARC-8 to UTF-8 conversion. Patch by Raj Patel.
12 Added option -m to GFS to control formatting of timestamps in log file.
14 Added 'exit' as synonym for 'quit' in yaz-client
16 Added support for specifying SRW resultSetId + resultSetIdleTime in a
17 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
18 for the new members. Patch by Ko van der Sloot.
20 Added support for SRU POST. It is supported for content-type
21 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
23 Do not build the separate Multi-threaded (MT) library libyazthread.la.
24 Instead make the library libyaz.la multi-threaded. Threading as a whole
25 can still be disabled by configure option --disable-threads. Previosly,
26 with older GLIBCs there were problems with MT libs under Apache. This
27 has now been fixed a long time ago.
29 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
32 CQL module modified to be case insensitive for relations/indexes/operations.
34 Fixed bug in CQL transform code: incorrect value relationModifieder
37 Added 'show all' command for yaz-client which retrieves all results
40 Added new yaz-client, xmles, which takes a (private) OID and
41 a document to be sent as an extended service request.
43 Describe new yaz-client commands wait_response and set_auto_wait.
45 Increase TCP/IP listener backlog from 3 (which I am guessing was
46 copied from the SunOS manual entry way back when) so SOMAXCONN, so
47 that the socket will queue as many incoming connections as it's able
48 to handle ongoing connections. In other words, it will never now
49 refuse a connection that it would be able to handle merely because
50 it's not got around to accepting() enough of the pending connections
51 yet. This is the behaviour anyway under Linux, where the listen()
52 argument is ignored; but not under BSD and on systems such as
53 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
54 YAZ-based servers should now be uniform across operating systems in
57 yaz-marcdump uses 64-bit file access on some systems. This is enabled
58 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
59 This allows yaz-marcdump to read large MARC batches (>2 GB).
61 Modified all YAZ source files - except the source which is auto-generated
62 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
65 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
66 corresponding to the existing *_setl() function. These allow option
67 values containing arbitrary valuues.
69 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
70 ZOOM_resultset_sort() in new applications. Its behaviour is identical
71 except that it returns an indicator of whether or not the sort
72 criterion was accepted (0 for OK, -1 for invalid).
76 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
77 MARC output rather than returning "new" buffer.
79 yaz-client warns about unknown init options.
81 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
85 Added support for SRW sort in Generic Frontend Server. Patch
86 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
87 sortKeys - or NULL if none is provided.
89 Fixed bug #307: It was impossible to specify indefinite/no timeout
90 for ZOOM_event. Special timeout value -1 now means indefinite timeout
93 Added support for multiple languages and charsets to be specified in
94 ZOOM. Each charset/language is separated by a blank. If negotiation is
95 in effect in init-response, Option
96 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
97 Code based on patch by Vasiliy Osadchuk.
99 Fixed bug #306: infinite recursion that occurred when calling
100 yaz_log_level_init as the first call (before other log level or
103 Fixed bug in scan handling in front end server: if preferred-Position-In-
104 Response was non-present, a NULL pointer referece was performed.
108 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
109 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
110 now defined for all those error codes. So instead of putting 109 in
111 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
112 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
114 Modified the yaz-marcdump utility to skip garbage bytes between MARC
117 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
119 Program yaz-client now exits and produces an error message if multiple
120 Z39.50 servers are specified on the command line (none or one allowed
123 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
128 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
130 Fixed bug #272: Preserve spacing for CCL terms.
134 Added support for virtual hosts and multiple backend servers for
135 the YAZ frontend server. The configution is XML based and
136 support specificition of CQL to RPN mappings and explain information.
137 See section "Virtual Hosts" in the YAZ manual.
139 Extended OPAC display utility. OPAC display utility renders
140 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
141 to supplement yaz_marc_decode_wrbuf.
143 Fixed a bug in MARC decoder that could caused it to crash for some
144 invalid MARC records. More diagnostics and warnings where added in
145 XML output (warnings, etc are stored in comments).
147 --- 2.0.34 2005/02/08
149 Fixes for UNIX domain sockets. Bug #261.
151 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
153 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
154 Added yaz_marc_subfield_str which defines subfield lead string which is
155 used in YAZ_MARC_LINE format. Default string is blank+$. Added
156 yaz_marc_endline_str which defines end of fields string used in
157 YAZ_MARC_LINE format. Default string is newline.
159 Experimental support for MarcXChange. This format can be produced
160 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
161 http://www.bs.dk/standards/MarcXchange.xsd
163 Added yaz-client commands scansize that sets maximum number of
164 entries to be returned by scan.
166 --- 2.0.32 2005/01/11
168 Added support for SRW scan in yaz-client and Generic Frontend Server.
170 * Added whereInList member to SRW Scan Term.
172 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
174 Fixed NMEM system to return aligned blocks on the smallest boundaries
175 that are suitably aligned for all possible types on the particular
176 architecture YAZ is being built for.
178 --- 2.0.30 2005/01/04
180 Fixed numerious warnings that was issued with newer versions of GCC.
182 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
183 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
186 Make YAZ Generic Frontend Server slightly faster.
188 Enhance (and reduce) logging for Generic Frontend Server.
190 Revert YAZ log system so that it flushes every write operation
191 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
193 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
194 instead of LOG_, due to name clash with syslog(3). LOG_ are still
195 present. New applications should define YAZ_USE_NEW_LOG=1 - this
196 will effectively disable old definitions.
198 --- 2.0.28 2004/11/09
200 Added yaz_log_time_format which specifies log format using
203 Added yaz_log_module_level which returns mask for a module. Value
204 is non-zero mask a if module is enabled; zero if disabled.
206 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
207 in include/yaz/cql.h.
209 Fixed bug #176: Dont throw diagnostics on empty SRU args.
211 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
213 Fixed bug #172: RPM builds does not enable SSL.
215 Doxyfile.in part of dist. Doxyfile generated by configure.
217 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
218 are given and the corresponding component does not exist.
220 Extend CCL documentation in YAZ reference. Describe r=r.
222 --- 2.0.26 2004/10/01
224 Fixed MARC->MARCXML conversion to properly deal with
225 fields, subfields, indicators having non-ASCII characters.
227 Fixed MARC->MARCXML conversion so that ASCII control characters
228 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
231 Added YAZ GFS support for conversion from Z39.50 surrogate
232 diagnostics to SRW surrogate diagnostics.
234 Bug fix: YAZ GFS did not return schema in explainResponse.
236 --- 2.0.25 2004/09/30
238 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
239 now converts recordSchema to elementSetName as well as schema URI.
241 Fixed bug in COMSTACK that prevented HTTP request packages from being
244 --- 2.0.24 2004/09/29
246 Added CCL facility r=r "range" which is similar to r=o "ordered" but
247 does not require white-space before and after the dash in a range, e.g.
248 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
251 Fixed a few AC_TRY_LINK configure tests that did not operate properly
252 due to new GCC removing "redundant" code.
254 Added yaz-client commands scanpos and scanstep that sets preferred
255 position and step-size for scan.
257 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
259 Added CCL utility ccl_qual_buf which parses one or more CCL
260 spec lines in a buffer.
262 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
263 of name and value - ignoring empty lines and comments.
265 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
267 Added odr_get_element_path which returns current element path for an
268 ODR handle. This utility is useful in error handling or user-defined
271 Added ODR_PRINT utility odr_set_stream which is is a more generic
272 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
273 to a write function and pointer to close function. The close function - if
274 non-NULL - will be called during odr_destroy.
276 Fixed bug in CCL parser where truncation char was not removed from
277 right side when truncation=both was in effect.
279 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
282 --- 2.0.23 2004/08/11
284 Fix buffer overrun in CQL parser when dealing with proximity (%).
286 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
287 to UTF-8/UCS conversion is now only based on codetables.xml.
289 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
291 --- 2.0.22 2004/08/06
293 Add support for more "commit changes" in ZOOM (uses Extended Services).
295 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
298 Yet another small fix for configure of SSL.
300 --- 2.0.21 2004/05/14
302 Fix SSL libs for configure when --with-openssl=DIR is given.
304 --- 2.0.20 2004/05/10
306 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
308 SSL comstack now uses yaz.pem certificate file on server side
309 by default. Certificate filename can be configured by calling
310 comstack function cs_set_ssl_certificate_file before cs_bind is used.
312 Fix bug regarding multiple calls to ZOOM_connection_connect.
314 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
316 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
317 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
319 ZOOM now allows inspection of X509 peer certificate for verification.
320 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
322 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
323 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
324 as "modular" but it simplifies things.
326 Added cs_get_peer_certificate to that returns peer X509 PEM.
328 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
329 NULL if SSL is unavailable.
331 Documentation about MARC decoding tools.
333 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
335 --- 2.0.19 2004/03/30
337 Rename CHANGELOG to NEWS to follow GNU style packing.
339 Fix bug with missing initialization of member in init_diagnostics.
340 This bug affects threaded version of GFS server.
342 --- 2.0.18 2004/03/20
344 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
347 Ensure zlib.dll is packed with Windows install.
349 --- 2.0.17 2004/03/17
351 Fix encoding of xsd:string to use text instead of CDATA.
353 Fix endless loop in CQL parser with unbalanced ".
355 Use a more compact way to store MARC-8 conversion tables.
357 --- 2.0.16 2004/03/16 Debian only
359 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
362 Update CQL parser to use new CQL 1.1 modifiers for booleans and
367 --- 2.0.15 2004/03/01
369 Another fix for decoding of XML packed records.
371 --- 2.0.14 2004/02/25
373 Fixes for Chunked encoding. White space not ignored after length spec.
375 Update NS and use default NS for SRW diagnostic elements.
377 --- 2.0.13 2004/02/23
379 Implement ZOOM_resultset_cache_reset which resets record cache.
381 Implement ZOOM_resultset_sort which sorts a result set.
383 Implement chunked HTTP transfer.
385 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
387 --- 2.0.12 2004/02/16
389 Added member 'schema' to bend_explain_rr structure so that backend
390 can specify explain record identifier. Defaults to Zeerex 2.0.
392 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
394 --- 2.0.11 2004/02/16
396 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
399 Added init command for yaz-client which sends "extra" init request.
401 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
402 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
404 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
406 Make ZOOM error code for "invalid query".
408 Fixed compilation for SSL which wasn't properly enabled for all platforms.
410 --- 2.0.10 2004/02/05
412 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
415 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
417 Added option -p <file> to make Generic Frontend Server to write PID file.
419 Added option -D to put Generic Frontend Server in background on its own.
421 Make ZOOM C recognize option "password". If unset, "pass" is used
422 (for backwards compatibility).
424 Fixed a bug in Generic Frontend Server that could make it crash if a
425 client sets characterSetNegotation bit, but didn't pass negotiation stuff
428 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
429 Must be issued before open, in order to be in effect.
431 --- 2.0.9-6 2004/01/12 Debian/Windows
433 Make the SRU server more picky WRT unknown params, etc.
435 Bug fix: ZOOM scan response didn't return displayTerm - when present.
437 New YAZ client command, options, that sets Z39.50 options.
439 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
440 options from a string of tokens (one token for each option bit).
442 Update SRW diagnostic code messages.
444 --- 2.0.9-5 2004/01/07 Debian/Windows
446 Handle user defined stylesheet for SRW/SRU.
448 --- 2.0.9-4 2004/01/06 Debian/Windows
450 Fix bug in decoding of Content-Length.
452 --- 2.0.9-3 2004/01/06 Debian/Windows
454 Fix a bug with decoding of XML packed records.
456 --- 2.0.9-2 2004/01/05 Debian only
458 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
460 Fix bug in SRW/SRU diagnostics decoding.
464 Fixed bug in Generic Frontend Server which could drop records exceeding
465 preferred message size. Reported and fixed by Irina Dijour.
467 Fixed calculation of package size for structured records in Generic
468 Frontend Server. Reported and fixed by Irina Dijour.
470 Fixed namespace for SRW/SRU diagnostics.
472 Fixed SEGV in yaz-client that occured for HTTP connection errors.
476 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
477 this version is incompatible with version 1.0 and older YAZ SRW/SRU
480 CQL changes to reflect recent changes to the specification:
481 * Documentation talks about context sets instead of index sets.
482 * Documentation talks about indexes instead of qualifiers.
483 * The CQL-to-PQF transformer's configuration file now uses
484 "index.set.name = <attributes>" instead of the old form
485 "qualifier.set.name = <attributes>". (Both forms are still
486 understood but the latter is deprecated.)
487 * CQL terms with no explicit index specified are now interpreted as
488 cql.serverChoice instead of srw.serverChoice (which of course
489 behaves exactly the same.)
493 MARC conversion can now generate ISO2709 output in another
494 character set. yaz-marcdump uses this facility if you invoke it
497 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
498 functions from there can be used from C++.
502 Frontend server now transfers memory from decoded packages to stream
505 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
506 references to show up.
508 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
509 the ZOOM Abstract API. The older names for the same options are still
510 also supported for the benefit of old applications.
512 ZOOM-C supports "implementationId" and "implementationVersion" options
513 to go along with "implementationName". These allow the user code to
514 specify identification strings to be sent to servers.
515 Add OID for the new ExtLite attribute set.
517 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
518 as requested/supplid by Ere Maijala <ere@atp.fi>
520 For generic frontend server, reverse the order of
521 "toolkit-supplied / application-supplied" strings sent as implementationId,
522 Name and Version. Also, remove the spaces around the slash. This brings
523 the GFS in line with the behaviour of ZOOM-C on the client side.
525 Add function ZOOM_scanset_display_term.
527 yaz-client shows scan displayTerm if present.
529 Utility yaz-iconv is now installed by default along with the man page
532 Extend configure check for OpenSSL to use pkg-config where available (such
535 Incorporate patch by Morten Bogeskov which allows a Unix file socket
536 server to specify uid/gid/mask for socket using the format
537 unix:[user=uid,][group=gid,][umask=mask,]file=path
538 If file= is omitted the existing format is assumed, e.g.
540 in which case the mask is 0666 (rw for everybody).
542 Major restructure of YAZ source. All source in libyaz is in src directory.
543 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
544 util (utility programs such as ASN.1 compiler, yaz-marcdump).
546 Added man page for utility yaz-marcdump (used to be called marcdump).
547 yaz-marcdump is installed by 'make install'.
549 Fixed a memory leak in Generic Frontend Server that occurred when decoding
550 of incoming package failed.
552 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
554 Change prototype of odr_perror: add const to message string.
556 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
558 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
559 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
560 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
561 DNS lookup. There should not be any compatibility problems with this
562 assuming that blocking=1 or 0 is used.
564 Fix bad reference in UNIX comstack in function cs_addrstr.
566 Fix for compilation on AIX.
568 The generic front-end server (server/seshigh.c) now supports returning
569 Init diagnostics to the client in User-information-field, in
570 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
575 Allow any CQL relation (not just all,any,exact,scr).
577 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
578 that features the same UI.
580 Implemented command update0 in YAZ client which is equivalent to
581 update but uses old of Ext Update ASN.1.
583 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
584 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
585 Previously no OID was used for this info.
587 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
588 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
589 returns 'malformed search term' otherwise.
591 SortResponse member resultCount now set to NULL in sort handler of
594 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
597 Add three new utility functions for translating OIDs between various
598 formats -- symbolic name such as "Usmarc", minus-1-terminated int
599 arrays and dotted strings such as "1.2.840.10003.9.5.1":
600 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
601 char *oid_to_dotstring(const int *oid, char *oidbuf);
602 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
604 Reverted modifications for ES Update definition for z_IU0Update
605 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
606 is back to YAZ 2.0.2.
608 String value attributes for CCL parser.
610 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
611 which their FirstSearch server returns in Init responses, sometimes
612 carrying useful diagnostic information when Init fails. This has the
613 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
614 "z39.50/oclcui.asn", where its definition is somewhat different from
615 what OCLC document on their web-site, as required to interoperate with
618 Support for anonymous authentication in yaz-client. Use the command
621 * Fix the OID of the Index Data-local "admin" Extended Service from
622 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
623 the 1000, which indicates a locally-defined OID, was a mistake.
627 Fix CCL directive @case handling so that it affects string match for
628 both CCL keywords and qualifiers.
630 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
631 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
632 Decoder has been updated with ASN.1 changes as listed in
633 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
634 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
635 z_IUUpdate, remains unchanged.
637 ZOOM_record_get may now return a record in a specific character set.
638 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
639 "from" is the character set of record as returned by target. "to" is
640 the character set to be returned. If omitted, "to" is UTF-8.
642 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
644 New ODR utility, odr_getelement, which returns name of element for
645 which encoding/decoding failed.
647 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
648 in cases where a required element was omitted.
650 Bug fix: some MARC8 sequences were not converted.
652 New ZOOM option "step" which specifies number of records to be
653 retrieved in one chunk. Used in conjunction with "start" and "count".
655 SRW support for yaz-client. Use scheme http: to use it, e.g.
658 yaz-client no longer does (un)intelligent character set conversions
659 by default. Can be enabled with charset and marc_charset commands.
661 xmalloc trace fix for 64-bit systems such as DEC alpha.
663 Solaris 2.6 compile fix.
665 New function, cql_strerror() translates SRW error codes, as returned
666 by cql_transform_error(), into human-readable English strings. Used
667 in yaz-client diagnostics when appropriate.
669 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
670 converts it into a type-1 query which is sent to the server. This
671 makes CQL available for use with all Z-servers, as opposed to the tiny
672 minority that can handle CQL queries themselves.
676 New Debian package layout similar to the Redhat Package layout.
678 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
679 and search result respectively.
683 Redhat package is now several packages: libyaz (runtime libraries),
684 libyaz-devel (development and documentation, and yaz (utility programs).
685 Package spec file by Morten Bøgeskov.
687 New member 'schema' in struct bend_fetch_rr which the name of requested
688 schema (SRW/SRU) for record (or NULL if none was given). The fetch
689 handler MAY set this to reflect the schema of the returned record.
691 New member 'display_term' in struct scan_entry. GFS now sets member entries
692 and allocates scan entries to be filled by user scan handler. In previous
693 version, entries member was allocated by the scan handler. That still works,
694 but the GFS will ignore member display_term - assuming it was NOT set by
695 the handler. The fact that the GFS now allocates the entries both allows
696 for new members and makes a scan handler easier to write.
698 Fix CQL lex buffer overflow.
700 SRW/SRU recordPacking. For SRW default recordPacking is string. For
701 SRU default recordPacking is string.
703 SRU protocol support for frontend server.
705 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
707 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
709 Added scan for the ZOOM shell (zoomsh).
713 * String Identifers for Schemas (Amendment 5).
714 http://lcweb.loc.gov/z3950/agency/amend/am5.html
715 Old definition for schema
716 Odr_oid *schema; /* OPT */
721 Z_InternationalString *uri;
722 #define Z_Schema_oid 1
723 #define Z_Schema_uri 2
726 * resultCount parameter to Sort Response (Amendment 1).
727 http://lcweb.loc.gov/z3950/agency/amend/am1.html
729 Support for SRW 1.0 over HTTP. This is an optional feature and
730 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
733 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
734 on the same port. SRW SearchRetrieveRequests are mapped
735 to bend_init,bend_search,bend_fetch,bend_close.
737 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
739 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
740 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
742 ZOOM connections are SRW based if schem http is used for hostname
743 in connect, e.g. z = ZOOM_connection_new("http://myserver");
744 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
746 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
747 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
748 distance=n, order=true/false, relation=le, prox unit=word. If
749 n is omitted, distance 1 is used.
751 Fixed problem with C compiler include path in wrong order.
753 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
754 on Solaris. Patch from Ko van der Sloot.
756 New MARC decode API. All new functions operate on a yaz_marc_t
757 handle. The most important new functions are: yaz_marc_create,
758 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
759 decode and destroy respectively. Decoder can produce formats
760 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
761 include/yaz/marcdisp.h.
763 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
764 to UTF-8, UCS-32, wchar_t or Latin-1.
766 * Prototypes for yaz_iconv_-functions moved to separate header
767 include/yaz/yaz-iconv.h.
769 Make a few private functions 'static' in unix.c. This prevents
770 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
772 For ZOOM connection, the options targetImplementation{Id,Name,Version}
773 are set when Init Response is received.
775 New function ZOOM_connection_error_x similar to ZOOM_connection_error
776 but returns diagnostic set as well.
778 New function yaz_strerror which is a portable wrapper for
779 strerror/strerror_r/GetLastMessage.
781 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
782 is returned for MARC. If type is "oai", then OAI MARC is returned.
784 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
789 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
791 Fix bad race conditions on SIGTERM and terminate gracefully in
794 Move retrieval (data1) module to Zebra since nobody seems to be
797 Add GRS-1 render for ZOOM using same format as yaz-client.
801 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
803 Fix broken ESpec handling in data1 module.
805 SGML reader parses comments and makes them part of the data1 tree.
807 Added several type casts so that YAZ compiles as C++ code.
809 ZOOM didn't handle PDU encoding failures properly.
811 Added more Bib-1 diagnostics (approved extensions).
813 GNU configure: better check for iconv.
815 More portable use of accept, getpeername. Check for socklen_t. Use
816 int/size_t if socklen_t is not defined.
820 PQF parser rejects bad queries - including those with extra
821 characters in them. PQF parser used to silently ignore that.
822 Cleaner API for PQF added, which allows you to get detailed
823 error information for bad queries (see yaz/pquery.h).
825 Fixed bug in ZOOM_record_get for type "database".
827 Implemented mini iconv library supporting conversions between
828 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
830 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
834 Fixed ZOOM C record cache so that preferredRecordSyntax and
835 elementSetName is used to check for already fetched records.
839 Added three members in bend_initrequest structure to facilitate
840 character set negotiation.
842 Fixed a bug in frontend server that could cause indefinite
843 loops under rare conditions.
845 Revised character set utilities (charneg.h) so that encoding
846 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
848 For PQF, directive @term <type> sets term type for Scan/Search.
849 Here <type> is general, string, numeric, null. The term type
850 is inherited - just like @attr.
852 New call odr_set_charset that sets character set conversion for
853 international-strings on a ODR stream. Prototype is:
854 int odr_set_charset(ODR o, const char *to, const char *from);
855 The InternationalString is still represented as C string in YAZ
856 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
857 won't). On the protocol level, you can use any encoding.
859 Support for UNIX sockets in ZOOM.
861 Solaris recv sometimes returns errno == ENOENT. It is treated as
862 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
864 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
865 both client and server. Code by Morten Bøgeskov.
869 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
870 that they can be used directly from Visual Basic. You must recompile
871 your windows APP if you're using ZOOM.
873 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
874 Commands "lang" and "charset" sets language and character set respectively.
875 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
876 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
878 Attributes from multiple CCL fields may be OR'ed rather than merged
879 using directive "@field or". Fields are still merged by default -
880 equivalent to "@field merge".
882 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
885 Fixed bug in zget for parameter ExtendedServicesResponse.
891 Added PQF feature: '@attr type=value' may be written as '@type=value'.
893 Client displays USR.1:SearchResult-1 (hits per term).
895 Additional Search Info for search in Generic Frontend Server.
897 Fixed CCL parsing of "field=s".
899 WIN32 installer - using the excellent NSIS software from nullsoft.
901 Fixed CCL parsing of "field = - <number>".
903 Added function yaz_marc_decode that decodes MARC for line mode
904 display or XML (similar to that used by JZKit).
906 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
907 Z39.50. But ISO/ILL was, however.
909 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
910 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
912 http://lcweb.loc.gov/z3950/agency/amend/am2.html
913 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
917 New YAZ client features: Command completion and new commands:
918 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
919 Code provided by Jacob Poulsen.
921 New call oid_trav, that visits all registered OIDs via callback.
923 Function ZOOM_record_get now returns const char pointer rather than
924 void pointer. It saves a lot of type casts.
926 For YAZ client, command "auth" now allows you to set authentication
927 in IdPass style. It is enabled when three tokens are given - order
928 is user, group and password.
930 Fix memory leaks in MARC record handling for ZOOM.
932 New option for YAZ client, -k <kilobytes> that sets
933 maximum record size. Similar to -k option for generic frontend
934 server and yaz-ztest.
936 More fixes for scan. Non-zero stepSize handled. OID's fixes.
938 Prefix query parser reports "fail" when bad attribute set is given.
940 Fix in MARC decoder. Proximity logging. Fix for attribute set
941 in scan handler for server. Patches by Shigeru Ishida.
943 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
946 Configure option --with-openssl=<dir> now works when a directory is
947 specified. Patch provided by Morten Bøgeskov.
949 New option for YAZ client, -u <auth>, that sets authentication.
951 ZOOM fix: error information was sometimes "missing", since error
952 was cleared/reset too when it shouldn't.
954 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
958 Scan for ZOOM API. New object ZOOM_scanset. New functions
959 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
960 ZOOM_scanset_destroy.
962 New ZOOM function, ZOOM_connection_last_event, that returns type
963 of last event (such as "receive data", "send data", "apdu received",
966 New ZOOM option, schema, that specifies schema for retrieval.
968 New CCL feature. Qualifiers can be aliases for one or more
969 other qualifiers (if more than one is given, OR is used).
971 ZOOM uses named result sets if target supports it.
973 Two new YAZ client commands: . (dot, which sources a script of YAZ
974 client commands), and ! (to execute shell command.). Implemented
977 Working on Debian packages.
981 YAZ client enables named result sets only if target supports it.
983 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
985 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
986 with key="host" to get same result.
988 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
989 Function Z3950_resultset_record(s) returns references to records
990 "owned" by resultset. To become owner use Z3950_record_clone.
992 Function z_ext_record handles Extended Services. Thanks to
997 CCL Parser fix: ignore token comma when dealing with and-lists.
999 Documentation updates for COMSTACK.
1001 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1002 Changed prototype Z3950_records. For some functions, int parameters
1003 were changed to size_t.
1005 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1008 New MARC decode/display function, marc_display_exl, which properly rejects
1009 non-ISO2709 records. YAZ client uses it.
1011 --- 1.8.1 2001/10/29
1013 Fix bug: local attribute set wasn't set correctly in PQF strings.
1017 * Old Z39.50 codecs no longer supported.
1019 Added ZOOM C binding. See http://zoom.z3950.org/
1021 Renamed states for COMSTACKs to avoid confusion with events.
1023 Implemented cs_look and proper cs_rcvconnect.
1025 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1027 Configure detects POSIX threads on OpenBSD.
1029 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1030 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1032 When error is returned from present handler, non-surrogate diagnostic
1033 is returned in present response (and fetch handler is no longer called).
1035 * Minor adjustments to pquery parser (PQF). Token characters may be
1036 escaped by using backslash (C-style).
1038 PQF parser allows string attribute values to be specified. For @attr,
1039 non-numeric characters after the equal-sign are treated as strings
1040 (e.g. @attr 9=title).
1042 CCL trunction character may be defined (@truncation in file)
1044 * function zget_ExtendedServicesRequest sets waitAction to
1045 waitIfPossible (was wait).
1047 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1050 CCL operator names may be set in field definition files (CCL_bibset).
1051 See ccl/bib1 for an example.
1053 Fixes in ASN.1 compiler for C++ compatibility.
1055 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1056 and "op_or" to avoid conflict with C++.
1058 Fixed problem with GNU readline detection on Redhat 7.0.
1060 Added step-size for Scan backend handler.
1062 Fixed bug that made the frontend server crash when no attribute
1063 set was specified for scan.
1065 Front-end server automatically switches to original working directory
1066 when installed as an NT service. Previously -w had to be specified to
1069 Added extended attributes for retrieval module (data1), so that data1
1070 records carry d1_readXML/SGML attributes. d1_read also supports
1071 null-data rules ( <tag/>)
1073 On UNIX when POSIX threads are available, a separate library libyazthread
1074 is created. Programmers should link with that library and the yaz library
1075 when using threads. The reason for the split was that some applications
1076 on Linux, such as Apache, doesn't work well when using shared objects that
1079 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1080 (or any frontend server) in SSL mode by specifying ssl: followed by
1081 address. Only tested on UNIX.
1083 Added feature for CCL module. Virtual structure s=al or s=ol generates
1084 and-list and or-list respectively instead of phrase search.
1088 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1089 log_mask_str. This was done to avoid name conflicts with other libraries
1090 (such as other PHP extensions).
1092 Added raw OID member for preferred record syntax (request_format_raw)
1093 and returned record syntax (output_format_raw) for backend fetch method.
1095 Config file yaz-config now accepts options so that it returns specific
1096 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1098 Shared library support for UNIX using GNU libtool.
1100 * Modified backend interface. Request/Response struct's replaced by
1101 one read/write C struct. For example bend_fetchrequest and
1102 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1103 Every handler - even search has to be registered in bend_init
1104 handler. This means that the YAZ library no longer refers to
1105 external functions and it makes it possible to make the whole
1106 thing a single DLL/SO.
1108 Added Segment handler for backend server.
1110 Added Zmbol/Zebra administrative functions to YAZ client.
1112 Threaded frontend server on UNIX (when POSIX Threads are available).
1113 Starting the server with option -T enables multi-threading.
1117 Added configure option --enable-comp/disable-comp to control use
1118 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1119 located in sub directory asn.
1121 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1122 in ${exec_prefix}/bin along with the other programs yaz-client and
1125 GNU automake used to maintain makefiles.
1127 Added several OID's.
1129 Changed retrieval module so that we can load records with no abstract
1130 syntax defined. Tagpaths in these records are fully composed of string
1133 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1137 On UNIX, the generated makefile now supports a proper 'make install'.
1138 The prefix can be set via GNU configure to set the install location
1139 (default is /usr/local).
1141 * YAZ programs client and ztest were renamed to yaz-client and
1142 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1143 locations, such as /usr/bin,/usr/local/bin,etc.
1145 * YAZ Header files were moved from include to include/yaz. YAZ Header
1146 files are referred to as include <yaz/log.h> rather than <log.h>.
1147 The YAZ include path (-I ..) is therefore the same as before. Programmers
1148 should update their #include statements or use -Ipath/include/yaz
1149 instead. The main motivation for doing this change is that YAZ header files
1150 can be installed in "standard" locations /usr/include,/usr/local/include
1151 without introducing conflicts, since ALL YAZ header files are stored
1152 in subdirectory yaz (under /usr/include for example).
1154 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1155 rather than project/workspace files. We switched because project files
1156 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1159 Changed name of logging function, logf, to yaz_log, to prevent name
1160 clash with some math-log functions. The YAZ header log.h defines logf
1161 to yaz_log (#define) so there should be no incompatibilities by this
1164 Added bend_start/bend_stop handlers for server. These handler are
1165 called on start/stop of server. For windows they are called whenever
1166 a service is started/stopped.
1168 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1169 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1170 in util/yc.tcl. The auto-generated C code structures are, in a few
1171 cases, incompatible with the old decoders. There are differences in the
1172 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1173 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1174 The preprocessor variable ASN_COMPILED is defined when the compiled
1175 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1176 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1177 wish to use the old encoders/decoders you can specify --disable-yc
1180 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1181 version so that it supports both new - and old version of DB Update
1183 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1184 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1185 change. The name parameter can be set to 0 in which no name is specified
1186 for the construction. The macros odr_implicit and odr_explicit sets name
1187 parameter to zero for the construction involved. New macros
1188 odr_implicit_tag and odr_explicit_tag are similar to the others,
1189 except that a name parameter is added. For programmers' that don't use
1190 ODR they probably only need to change the call to z_APDU and z_External.
1192 Added access control facility by interfacing the TCP wrapper library.
1193 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1194 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1195 name of the daemon and enables the access control as specified in
1196 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1198 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1199 den Dool <H.M.vdnDool@kub.nl>.
1201 Added reference ID parameter to most functions in server API - refer
1202 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1204 Changed name of ccl library to libccl.a (was ccl.a).
1206 Fixed bug in decoder for Explain (Category TargetInfo).
1208 Added support for GNU readline in client. Thanks to Jacob Poulsen
1209 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1211 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1212 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1213 IMPLEMENTATION! This change was made to the development version before
1214 the ZIG decided to retract the amendment. If any users MUST be
1215 compatible with the original Update definition, PLEASE CONTACT US, and
1216 we will include a separate definition corresponding to the old Update
1217 ES. Note that because of the change to the ASN.1 of the
1218 TaskPackageRecordStructure we cannot define a single structure that
1219 will support both versions.
1221 * Added const modifier to buffer parameter for some ODR/BER encoding
1222 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1223 completeWAIS, odr_dumpBER.
1225 Fixed bug in client.c which caused a crash when a scanResponse didn't
1226 contain positionOfTerm.
1228 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1229 * will cause an error in a client if a non-YAZ target sends both a
1230 * list of Scan entries and non-surrogate diagnostics.
1232 Retrieval module enhancements. Tag sets may be typed in the reference
1233 to it. From the .abs-file the "tagset" directive takes a third optional
1234 integer type for the tag set referenced. From a .tag-file the "include"
1235 directive takes a third optional type as well. The old "type" directive
1236 in the tag set itself is still recognized but acts as the default type
1239 Backend interface change. Individual Scan terms returned from bend_scan
1240 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1241 in include/backend.h.
1243 Retrieval module enhancements. Multiple tag sets and attribute sets may
1244 be specified in abstract syntax specs. Revised the error/warning for
1245 logging messages reported by the retrieval module when reading the
1248 Object Identifier system (oid_..) changed. The API is backwards
1249 compatible but the oid-routines now allocates new OID's when needed.
1250 Raw OID's may be specified in oid_getvalbyname.
1252 YAZ now uses GNU configure to generate Makefile(s).
1254 * Minor changes in some of the member names of DeleteResultSetRequest and
1255 DeleteResultSetResponse. See include/proto.h.
1257 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1258 and added member 'languages' in TargetInfo (which was missing).
1260 Changed the way attribute sets are handled in the retrieval
1261 module. These are now cached, just like the abstract syntaxes
1264 Changed YAZ so that it links with compiled ASN.1.
1266 Added Explain-schema definitions and mapping routines. The following
1267 Explain categories have been implemented: AttributeDetails,
1268 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1270 Fixed minor bug in Windows version of Server Library.
1272 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1274 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1276 Added EXTERNAL: UNIverse Resource Report (non-standard).
1278 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1279 ENUMERATED and SET OF.
1281 * Added 'const' to some of the char pointer arguments for the
1282 functions, data1_read_node, data1_getelementbytagname,
1283 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1286 Fixed bug in data1_insert_taggeddata - the last_child member of
1287 parent wasn't initialised.
1289 * Changed data1_read_record and data1_read_node so that the supplied
1290 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1291 doesn't refer to any parts of the "SGML"-buffer.
1293 Fixed bug in server library (Windows version of statserv_remove).
1295 * Changed code so that it compiles as C++. The type definition
1296 of Odr_fun which is a member of Odr_arm was changed. The result is,
1297 that an explicit typecast is needed for the fun pointer when
1298 using Odr_arm - as in:
1299 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1301 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1303 Implemented the new structured date and time definition as approved
1304 by the ZIG. Added schemaId element to the specificTag in Espec-1
1305 (also approved at the last ZIG). Thanks to RVDM.
1307 Added some Object identifiers (RVDM).
1309 Changed the Update Extended Service (RVDM).
1311 Added command "refid" to client which specifies referenceId for
1312 the following requests.
1314 Implemented extended service handling for server. See ztest.c
1315 for an example as well as backend.h. New handlers are registerd
1316 in the Init handler.
1318 * Changed interface for sort in server.
1320 Added new members to statserv_options_block. It allows a server
1321 to read options from another source than just the command line. Thanks
1322 to Charles Woodfield.
1324 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1325 renamed to zboolean. Some C++ compilers complained about the name.
1327 Minor changes to gils.abs. Added index 's' (sort) on title
1328 and date/time-last-modified.
1330 --- 1.4pl2 1998/1/30
1332 Fixed bug in server library regarding inetd mode (-i). This bug
1333 was introduced by release 1.4.
1335 --- 1.4pl1 1998/1/29
1337 Added sort facility in client and backend server interface.
1339 Fixed problem with dependencies in Makefile(s).
1341 Fixed bugs for encoders/decoders of extended services and
1344 Implemented sub-tree feature for schemas. Sub-trees are
1345 referenced in *.abs-files. See explain.abs for an example
1346 of the use of this feature.
1348 Modified bib1.att; local attributes for ANY didn't include
1349 ANY itself (only affects use of the retrieval module).
1351 Fixed bug in plain SGML reader in function data1_read_node:
1352 tags with prefix "var" was incorrectly interpreted as variants.
1354 Added feature "sub-schemas" to enable references to - and definitions
1355 of - group of elements.
1357 * Removed member parent from type data1_element (in data1.h).
1359 Implemented function odr_nullval() that returns the value of
1362 * Removed member num_children from data1_node (in data1.h).
1364 Made NT service interface part of the server library. The
1365 function statserv_main uses the NT service when required and
1366 calls the statserv_start / statserv_close routines.
1368 Routine zget_SearchRequest and zget_PresentRequest fills
1369 resultSetName/Id member with "default" instead of "Default".
1371 Fixed memory leak in server. Request queue member wasn't freed.
1373 Fixed nmem_exit so that memory is freed.
1377 Revised the CCL parser utility to be thread safe.
1379 Added function, oid_ent_to_oid, to replace the function
1380 oid_getoidbyent, which is not thread safe.
1382 * Added nmem_init and nmem_exit to initialize and release
1383 NMEM resources. Function nmem_init should be called once in the
1384 initial thread before NMEM/ODR is used. statserv.c and client.c
1385 have been changed accordingly. The change was necessary to make
1386 NMEM thread safe. The NMEM memory pool is shared amongst threads
1387 in a process. Unix-based applications will still work fine without
1390 Added NT Services interface for the the Z39.50 (statserv) Server.
1391 Refer to the ztest.c source on the usage.
1393 Windows 95/NT port using MSVC5.0. Project files are included in the
1396 * Defined new 'global' handle for the retrieval (data1) system. The
1397 new handled, data1_handle, describes the state of the data1 system.
1398 This handle is passed as first argument to virtually all
1399 data1 related routines. The functions data1_create and data1_destroy
1400 creates and destroys a data1 handle respectively.
1402 Added ODR encode stream member to all backend request structures
1403 init, search, scan etc. This stream should be used to allocate all
1404 memory used for the response when thread safe operation is needed.
1406 Changed the comstack utility, cs_addstr, to be thread safe. The
1407 returned hostname string returned by the function is now part the
1410 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1411 function. The cs_straddr takes a COMSTACK handle as argument, so this
1412 function must be used after cs_create and before bind/connect.
1413 This function is thread safe.
1415 Moved test server to 'ztest' directory - generic server code still
1416 in 'server' directory.
1418 Made prefix query (pquery.c) utility thread safe.
1420 Added new function modifier YAZ_EXPORT to 'export' public DLL
1421 functions when using windows (see include/yconfig.h).
1423 Added definitions to the OID database (util/oid.c) (RVDM).
1425 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1427 Added call to ccl_rpn_delete in client program.
1429 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1430 release of RPN structure.
1432 Added support for C++, headers uses extern "C" for public definitions.
1433 With input from RVDM.
1435 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1436 Thanks to Ronald van der Meer (RVDM).
1438 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1440 Added support for private extensions to the OID database
1441 (oid_setprivateoids()). Thanks to RVDM.
1443 Added optional, physical ANY (key replication)
1445 Fixed null-reference problem in GRS-1 output filter.
1447 Proximity operator added to Prefix Query Format (PQF).
1449 In test client command "base" accepts multiple databases.
1451 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1455 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1457 Smallish bug-fixes in the new encoders/decoders (explain).
1459 Bug fixed in DeleteRequest.
1461 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1463 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1465 Added SOIF syntax (using private OID for now) to retrieval module and client.
1467 Added Update extended service.
1469 Added SearchResult-1 additional info structure.
1471 Added optional CCL (ISO8777) interpreter as separate module. Available
1474 --- 1.2 1996/6/10 (1st anniversary release)
1476 Added Summary record syntax. Lightly tested.
1478 Added OPAC record syntax. Untested.
1480 Added ResourceReport service encoders/decoders. Untested.
1482 Fixed bug in z_Unit - wrong tagging on unitSystem.
1484 Fixed bug in the DiagRecs decoder.
1486 Added options for max PDU size and session timeout to frontend-server.
1488 Added documentation of query-language parsers and other supporting utilities.
1490 [frontend-server] Added Attribute set to the bend_scanrequest API.
1492 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1493 surrogate diagnostics were generated.
1495 [retrieval] Allow multiple local values for attribute.
1497 [retrieval] Allow multiple attributes per element in .abs files. index type.
1499 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1501 --- 1.1pl2 1996/4/10
1503 Minor changes, mostly specific to Zebra's requirements (retrieval)
1507 Repaired bug in frontend server when running multiple listening
1508 endpoints in dynamic mode.
1510 z_External() now won't break if a known, ASN.1 value comes encapsulated
1511 in an octet-string. The value will pass through unmodified in an Odr_oct.
1513 Added a bit of code to the demo client to decode & display
1514 ASN.1-structured records represented in the octet-aligned branch of
1515 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1517 Added z_ext_getentbyref() to the ASN module. Doc updated.
1519 * Completed the SCAN definition in the ASN module. This may break SCAN
1520 code based on older YAZ-versions at compile-time. The fix is easy -
1523 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1524 under the SCAN definition. Remember to initialize this, server-people.
1526 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1527 that this does not extend to ODR and ASN.
1529 Comstack allows insertion of established socket (primarily for
1530 inetd-operation of servers). Doc updated.
1532 Front-end server can now start from the inetd in TCP mode. Doc
1535 --- 1.0pl4 1996/1/24
1539 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1540 the rank and record number.
1542 Adjustments to the frontend server.
1544 Fixed diagnostic BER dumper. It ignored the file argument.
1548 Various changes to retrieval module.
1550 Changed the union discriminators of the protocol files from enums to
1551 ints paired with #defines.
1553 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1556 *Changed operator in the RPN structure to 'roperator', again to avoid a
1559 Fixed problems in Explain decoders/encoders.
1561 --- 1.0pl2 1995/12/6
1563 Memory bug in log module fixed.
1565 --- 1.0pl1 1995/12/5
1567 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1569 Bug in Explain DatabaseInfo module fixed.
1571 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1575 The shift to v1.0 signals that we now consider the *core* functionality
1576 of YAZ reasonably stable (the core being more or less equivalent to
1577 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1578 tested (Explain not at all - though that will happen soonish).
1580 Minor changes to code to support Windows port.
1582 Various minor changes after we're getting to use GRS-1 & co. more.
1584 Added Espec-1 format.
1586 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1587 of the protocol and it cannot be selected when encoding (maps into 'string'
1588 when decoding). Needed to talk to some servers.
1590 Demo client can request simple element set names.
1592 Added Diagnostic Format encoders/decoders.
1594 Added simple Close handling to frontend server (no hooks for resource
1595 reporting yet), and demonstration client.
1597 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1599 --- 1.0b3 1995/08/24
1601 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1602 handled incorrectly when records were requested in the searchResponse. This
1603 will only affect you if you use the frontend-server.
1605 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1606 Test-client will ask for and print GRS1. Ztest will return dummy records
1609 Added Explain encoders/decoders to the service-level API. Untested.
1611 Added Extended Services: Item Order encoders and decoders to the Service-
1612 level API. Untested. We could use a recent copy of the pertinent bits
1613 of the ILL protocol to add those bits.
1615 Added diagnostic format 1 encoders/decoders to the service-level API.
1618 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1619 odr_cons.c, which causes a more correct output.
1621 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1622 was always set to 0 when no records were requested in the searchRequest.
1624 * Added better external-handling. This shouldn't harm old code that
1625 *encodes* externals. It can break code that looks for a
1626 'single-ASN1-type' representation, since those types that are known
1627 are now decoded immediately. Look at the SUTRS sample code in
1628 seshigh.c and client.c. Documentation updated.
1630 Handling of structured records in bend_fetchresponse. Length -1 marks
1631 structured record, type is deduced from format field.
1633 --- 1.0b2 1995/06/27
1634 Fairly quick maintenance release to add SUTRS support.
1636 Fixed handling of SUTRS records in the demonstration client.
1638 * Added format field to the bend_fetchrequest and bend_fetchresponce
1639 structures of the backend API (frontend server). When the record is
1640 returned, the value of the format field is mapped to an OID. The
1641 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1642 of the record. The special value VAL_NONE in the bend_request means
1643 that no specific format was requested by the client. Documentation
1644 updated accordingly. Test server (ztest) will return a fixed dummy
1645 SUTRS record if your client requests SUTRS.
1647 Documentation updated accordingly.
1649 You can now set external libraries and RANLIB support in the top-level
1653 First public release.
