3 Fixed bug in yaz_oi_update which uesd incorrect value for categoryValue.
5 In ZOOM socket code, use select instead of poll on MacOSX.
7 ZOOM-C now support client-side compilation of CQL into RPN that is
8 sent to the server, enabling CQL to be used against all Z39.50
9 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
10 ZOOM_query object, and submit it using ZOOM_connection_search().
11 The CQL-to-RPN translation uses a configuration file, the name of
12 which must be specified in the Connection's "cqlfile" option.
14 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
15 function, which takes as its start-term parameter a ZOOM_query object
16 (which may have had either CQL or RPN set into it).
21 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
22 GFS to support this as well. Backend handler, bend_srw_update, does the
23 update work. Code contributed by Ko van der Sloot.
25 Allow retrieval of Search Result-1 information in ZOOM by the use of
26 options that are attached to a result set. ZOOM documentation updated
29 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
30 UTF-8 conversion. Patch by Raj Patel.
32 Added option -m to GFS to control formatting of timestamps in log file.
34 Added 'exit' as synonym for 'quit' in yaz-client
36 Added support for specifying SRW resultSetId + resultSetIdleTime in a
37 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
38 for the new members. Patch by Ko van der Sloot.
40 Added support for SRU POST. It is supported for content-type
41 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
43 Do not build the separate Multi-threaded (MT) library libyazthread.la.
44 Instead make the library libyaz.la multi-threaded. Threading as a whole
45 can still be disabled by configure option --disable-threads. Previosly,
46 with older GLIBCs there were problems with MT libs under Apache. This
47 has now been fixed a long time ago.
49 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
52 CQL module modified to be case insensitive for relations/indexes/operations.
54 Fixed bug in CQL transform code: incorrect value relationModifieder
57 Added 'show all' command for yaz-client which retrieves all results
60 Added new yaz-client, xmles, which takes a (private) OID and
61 a document to be sent as an extended service request.
63 Describe new yaz-client commands wait_response and set_auto_wait.
65 Increase TCP/IP listener backlog from 3 (which I am guessing was
66 copied from the SunOS manual entry way back when) so SOMAXCONN, so
67 that the socket will queue as many incoming connections as it's able
68 to handle ongoing connections. In other words, it will never now
69 refuse a connection that it would be able to handle merely because
70 it's not got around to accepting() enough of the pending connections
71 yet. This is the behaviour anyway under Linux, where the listen()
72 argument is ignored; but not under BSD and on systems such as
73 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
74 YAZ-based servers should now be uniform across operating systems in
77 yaz-marcdump uses 64-bit file access on some systems. This is enabled
78 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
79 This allows yaz-marcdump to read large MARC batches (>2 GB).
81 Modified all YAZ source files - except the source which is auto-generated
82 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
85 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
86 corresponding to the existing *_setl() function. These allow option
87 values containing arbitrary valuues.
89 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
90 ZOOM_resultset_sort() in new applications. Its behaviour is identical
91 except that it returns an indicator of whether or not the sort
92 criterion was accepted (0 for OK, -1 for invalid).
96 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
97 MARC output rather than returning "new" buffer.
99 yaz-client warns about unknown init options.
101 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
105 Added support for SRW sort in Generic Frontend Server. Patch
106 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
107 sortKeys - or NULL if none is provided.
109 Fixed bug #307: It was impossible to specify indefinite/no timeout
110 for ZOOM_event. Special timeout value -1 now means indefinite timeout
113 Added support for multiple languages and charsets to be specified in
114 ZOOM. Each charset/language is separated by a blank. If negotiation is
115 in effect in init-response, Option
116 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
117 Code based on patch by Vasiliy Osadchuk.
119 Fixed bug #306: infinite recursion that occurred when calling
120 yaz_log_level_init as the first call (before other log level or
123 Fixed bug in scan handling in front end server: if preferred-Position-In-
124 Response was non-present, a NULL pointer referece was performed.
128 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
129 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
130 now defined for all those error codes. So instead of putting 109 in
131 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
132 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
134 Modified the yaz-marcdump utility to skip garbage bytes between MARC
137 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
139 Program yaz-client now exits and produces an error message if multiple
140 Z39.50 servers are specified on the command line (none or one allowed
143 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
148 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
150 Fixed bug #272: Preserve spacing for CCL terms.
154 Added support for virtual hosts and multiple backend servers for
155 the YAZ frontend server. The configution is XML based and
156 support specificition of CQL to RPN mappings and explain information.
157 See section "Virtual Hosts" in the YAZ manual.
159 Extended OPAC display utility. OPAC display utility renders
160 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
161 to supplement yaz_marc_decode_wrbuf.
163 Fixed a bug in MARC decoder that could caused it to crash for some
164 invalid MARC records. More diagnostics and warnings where added in
165 XML output (warnings, etc are stored in comments).
167 --- 2.0.34 2005/02/08
169 Fixes for UNIX domain sockets. Bug #261.
171 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
173 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
174 Added yaz_marc_subfield_str which defines subfield lead string which is
175 used in YAZ_MARC_LINE format. Default string is blank+$. Added
176 yaz_marc_endline_str which defines end of fields string used in
177 YAZ_MARC_LINE format. Default string is newline.
179 Experimental support for MarcXChange. This format can be produced
180 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
181 http://www.bs.dk/standards/MarcXchange.xsd
183 Added yaz-client commands scansize that sets maximum number of
184 entries to be returned by scan.
186 --- 2.0.32 2005/01/11
188 Added support for SRW scan in yaz-client and Generic Frontend Server.
190 * Added whereInList member to SRW Scan Term.
192 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
194 Fixed NMEM system to return aligned blocks on the smallest boundaries
195 that are suitably aligned for all possible types on the particular
196 architecture YAZ is being built for.
198 --- 2.0.30 2005/01/04
200 Fixed numerious warnings that was issued with newer versions of GCC.
202 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
203 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
206 Make YAZ Generic Frontend Server slightly faster.
208 Enhance (and reduce) logging for Generic Frontend Server.
210 Revert YAZ log system so that it flushes every write operation
211 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
213 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
214 instead of LOG_, due to name clash with syslog(3). LOG_ are still
215 present. New applications should define YAZ_USE_NEW_LOG=1 - this
216 will effectively disable old definitions.
218 --- 2.0.28 2004/11/09
220 Added yaz_log_time_format which specifies log format using
223 Added yaz_log_module_level which returns mask for a module. Value
224 is non-zero mask a if module is enabled; zero if disabled.
226 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
227 in include/yaz/cql.h.
229 Fixed bug #176: Dont throw diagnostics on empty SRU args.
231 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
233 Fixed bug #172: RPM builds does not enable SSL.
235 Doxyfile.in part of dist. Doxyfile generated by configure.
237 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
238 are given and the corresponding component does not exist.
240 Extend CCL documentation in YAZ reference. Describe r=r.
242 --- 2.0.26 2004/10/01
244 Fixed MARC->MARCXML conversion to properly deal with
245 fields, subfields, indicators having non-ASCII characters.
247 Fixed MARC->MARCXML conversion so that ASCII control characters
248 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
251 Added YAZ GFS support for conversion from Z39.50 surrogate
252 diagnostics to SRW surrogate diagnostics.
254 Bug fix: YAZ GFS did not return schema in explainResponse.
256 --- 2.0.25 2004/09/30
258 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
259 now converts recordSchema to elementSetName as well as schema URI.
261 Fixed bug in COMSTACK that prevented HTTP request packages from being
264 --- 2.0.24 2004/09/29
266 Added CCL facility r=r "range" which is similar to r=o "ordered" but
267 does not require white-space before and after the dash in a range, e.g.
268 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
271 Fixed a few AC_TRY_LINK configure tests that did not operate properly
272 due to new GCC removing "redundant" code.
274 Added yaz-client commands scanpos and scanstep that sets preferred
275 position and step-size for scan.
277 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
279 Added CCL utility ccl_qual_buf which parses one or more CCL
280 spec lines in a buffer.
282 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
283 of name and value - ignoring empty lines and comments.
285 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
287 Added odr_get_element_path which returns current element path for an
288 ODR handle. This utility is useful in error handling or user-defined
291 Added ODR_PRINT utility odr_set_stream which is is a more generic
292 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
293 to a write function and pointer to close function. The close function - if
294 non-NULL - will be called during odr_destroy.
296 Fixed bug in CCL parser where truncation char was not removed from
297 right side when truncation=both was in effect.
299 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
302 --- 2.0.23 2004/08/11
304 Fix buffer overrun in CQL parser when dealing with proximity (%).
306 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
307 to UTF-8/UCS conversion is now only based on codetables.xml.
309 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
311 --- 2.0.22 2004/08/06
313 Add support for more "commit changes" in ZOOM (uses Extended Services).
315 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
318 Yet another small fix for configure of SSL.
320 --- 2.0.21 2004/05/14
322 Fix SSL libs for configure when --with-openssl=DIR is given.
324 --- 2.0.20 2004/05/10
326 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
328 SSL comstack now uses yaz.pem certificate file on server side
329 by default. Certificate filename can be configured by calling
330 comstack function cs_set_ssl_certificate_file before cs_bind is used.
332 Fix bug regarding multiple calls to ZOOM_connection_connect.
334 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
336 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
337 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
339 ZOOM now allows inspection of X509 peer certificate for verification.
340 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
342 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
343 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
344 as "modular" but it simplifies things.
346 Added cs_get_peer_certificate to that returns peer X509 PEM.
348 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
349 NULL if SSL is unavailable.
351 Documentation about MARC decoding tools.
353 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
355 --- 2.0.19 2004/03/30
357 Rename CHANGELOG to NEWS to follow GNU style packing.
359 Fix bug with missing initialization of member in init_diagnostics.
360 This bug affects threaded version of GFS server.
362 --- 2.0.18 2004/03/20
364 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
367 Ensure zlib.dll is packed with Windows install.
369 --- 2.0.17 2004/03/17
371 Fix encoding of xsd:string to use text instead of CDATA.
373 Fix endless loop in CQL parser with unbalanced ".
375 Use a more compact way to store MARC-8 conversion tables.
377 --- 2.0.16 2004/03/16 Debian only
379 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
382 Update CQL parser to use new CQL 1.1 modifiers for booleans and
387 --- 2.0.15 2004/03/01
389 Another fix for decoding of XML packed records.
391 --- 2.0.14 2004/02/25
393 Fixes for Chunked encoding. White space not ignored after length spec.
395 Update NS and use default NS for SRW diagnostic elements.
397 --- 2.0.13 2004/02/23
399 Implement ZOOM_resultset_cache_reset which resets record cache.
401 Implement ZOOM_resultset_sort which sorts a result set.
403 Implement chunked HTTP transfer.
405 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
407 --- 2.0.12 2004/02/16
409 Added member 'schema' to bend_explain_rr structure so that backend
410 can specify explain record identifier. Defaults to Zeerex 2.0.
412 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
414 --- 2.0.11 2004/02/16
416 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
419 Added init command for yaz-client which sends "extra" init request.
421 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
422 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
424 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
426 Make ZOOM error code for "invalid query".
428 Fixed compilation for SSL which wasn't properly enabled for all platforms.
430 --- 2.0.10 2004/02/05
432 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
435 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
437 Added option -p <file> to make Generic Frontend Server to write PID file.
439 Added option -D to put Generic Frontend Server in background on its own.
441 Make ZOOM C recognize option "password". If unset, "pass" is used
442 (for backwards compatibility).
444 Fixed a bug in Generic Frontend Server that could make it crash if a
445 client sets characterSetNegotation bit, but didn't pass negotiation stuff
448 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
449 Must be issued before open, in order to be in effect.
451 --- 2.0.9-6 2004/01/12 Debian/Windows
453 Make the SRU server more picky WRT unknown params, etc.
455 Bug fix: ZOOM scan response didn't return displayTerm - when present.
457 New YAZ client command, options, that sets Z39.50 options.
459 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
460 options from a string of tokens (one token for each option bit).
462 Update SRW diagnostic code messages.
464 --- 2.0.9-5 2004/01/07 Debian/Windows
466 Handle user defined stylesheet for SRW/SRU.
468 --- 2.0.9-4 2004/01/06 Debian/Windows
470 Fix bug in decoding of Content-Length.
472 --- 2.0.9-3 2004/01/06 Debian/Windows
474 Fix a bug with decoding of XML packed records.
476 --- 2.0.9-2 2004/01/05 Debian only
478 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
480 Fix bug in SRW/SRU diagnostics decoding.
484 Fixed bug in Generic Frontend Server which could drop records exceeding
485 preferred message size. Reported and fixed by Irina Dijour.
487 Fixed calculation of package size for structured records in Generic
488 Frontend Server. Reported and fixed by Irina Dijour.
490 Fixed namespace for SRW/SRU diagnostics.
492 Fixed SEGV in yaz-client that occured for HTTP connection errors.
496 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
497 this version is incompatible with version 1.0 and older YAZ SRW/SRU
500 CQL changes to reflect recent changes to the specification:
501 * Documentation talks about context sets instead of index sets.
502 * Documentation talks about indexes instead of qualifiers.
503 * The CQL-to-PQF transformer's configuration file now uses
504 "index.set.name = <attributes>" instead of the old form
505 "qualifier.set.name = <attributes>". (Both forms are still
506 understood but the latter is deprecated.)
507 * CQL terms with no explicit index specified are now interpreted as
508 cql.serverChoice instead of srw.serverChoice (which of course
509 behaves exactly the same.)
513 MARC conversion can now generate ISO2709 output in another
514 character set. yaz-marcdump uses this facility if you invoke it
517 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
518 functions from there can be used from C++.
522 Frontend server now transfers memory from decoded packages to stream
525 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
526 references to show up.
528 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
529 the ZOOM Abstract API. The older names for the same options are still
530 also supported for the benefit of old applications.
532 ZOOM-C supports "implementationId" and "implementationVersion" options
533 to go along with "implementationName". These allow the user code to
534 specify identification strings to be sent to servers.
535 Add OID for the new ExtLite attribute set.
537 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
538 as requested/supplid by Ere Maijala <ere@atp.fi>
540 For generic frontend server, reverse the order of
541 "toolkit-supplied / application-supplied" strings sent as implementationId,
542 Name and Version. Also, remove the spaces around the slash. This brings
543 the GFS in line with the behaviour of ZOOM-C on the client side.
545 Add function ZOOM_scanset_display_term.
547 yaz-client shows scan displayTerm if present.
549 Utility yaz-iconv is now installed by default along with the man page
552 Extend configure check for OpenSSL to use pkg-config where available (such
555 Incorporate patch by Morten Bogeskov which allows a Unix file socket
556 server to specify uid/gid/mask for socket using the format
557 unix:[user=uid,][group=gid,][umask=mask,]file=path
558 If file= is omitted the existing format is assumed, e.g.
560 in which case the mask is 0666 (rw for everybody).
562 Major restructure of YAZ source. All source in libyaz is in src directory.
563 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
564 util (utility programs such as ASN.1 compiler, yaz-marcdump).
566 Added man page for utility yaz-marcdump (used to be called marcdump).
567 yaz-marcdump is installed by 'make install'.
569 Fixed a memory leak in Generic Frontend Server that occurred when decoding
570 of incoming package failed.
572 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
574 Change prototype of odr_perror: add const to message string.
576 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
578 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
579 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
580 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
581 DNS lookup. There should not be any compatibility problems with this
582 assuming that blocking=1 or 0 is used.
584 Fix bad reference in UNIX comstack in function cs_addrstr.
586 Fix for compilation on AIX.
588 The generic front-end server (server/seshigh.c) now supports returning
589 Init diagnostics to the client in User-information-field, in
590 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
595 Allow any CQL relation (not just all,any,exact,scr).
597 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
598 that features the same UI.
600 Implemented command update0 in YAZ client which is equivalent to
601 update but uses old of Ext Update ASN.1.
603 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
604 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
605 Previously no OID was used for this info.
607 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
608 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
609 returns 'malformed search term' otherwise.
611 SortResponse member resultCount now set to NULL in sort handler of
614 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
617 Add three new utility functions for translating OIDs between various
618 formats -- symbolic name such as "Usmarc", minus-1-terminated int
619 arrays and dotted strings such as "1.2.840.10003.9.5.1":
620 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
621 char *oid_to_dotstring(const int *oid, char *oidbuf);
622 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
624 Reverted modifications for ES Update definition for z_IU0Update
625 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
626 is back to YAZ 2.0.2.
628 String value attributes for CCL parser.
630 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
631 which their FirstSearch server returns in Init responses, sometimes
632 carrying useful diagnostic information when Init fails. This has the
633 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
634 "z39.50/oclcui.asn", where its definition is somewhat different from
635 what OCLC document on their web-site, as required to interoperate with
638 Support for anonymous authentication in yaz-client. Use the command
641 * Fix the OID of the Index Data-local "admin" Extended Service from
642 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
643 the 1000, which indicates a locally-defined OID, was a mistake.
647 Fix CCL directive @case handling so that it affects string match for
648 both CCL keywords and qualifiers.
650 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
651 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
652 Decoder has been updated with ASN.1 changes as listed in
653 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
654 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
655 z_IUUpdate, remains unchanged.
657 ZOOM_record_get may now return a record in a specific character set.
658 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
659 "from" is the character set of record as returned by target. "to" is
660 the character set to be returned. If omitted, "to" is UTF-8.
662 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
664 New ODR utility, odr_getelement, which returns name of element for
665 which encoding/decoding failed.
667 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
668 in cases where a required element was omitted.
670 Bug fix: some MARC8 sequences were not converted.
672 New ZOOM option "step" which specifies number of records to be
673 retrieved in one chunk. Used in conjunction with "start" and "count".
675 SRW support for yaz-client. Use scheme http: to use it, e.g.
678 yaz-client no longer does (un)intelligent character set conversions
679 by default. Can be enabled with charset and marc_charset commands.
681 xmalloc trace fix for 64-bit systems such as DEC alpha.
683 Solaris 2.6 compile fix.
685 New function, cql_strerror() translates SRW error codes, as returned
686 by cql_transform_error(), into human-readable English strings. Used
687 in yaz-client diagnostics when appropriate.
689 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
690 converts it into a type-1 query which is sent to the server. This
691 makes CQL available for use with all Z-servers, as opposed to the tiny
692 minority that can handle CQL queries themselves.
696 New Debian package layout similar to the Redhat Package layout.
698 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
699 and search result respectively.
703 Redhat package is now several packages: libyaz (runtime libraries),
704 libyaz-devel (development and documentation, and yaz (utility programs).
705 Package spec file by Morten Bøgeskov.
707 New member 'schema' in struct bend_fetch_rr which the name of requested
708 schema (SRW/SRU) for record (or NULL if none was given). The fetch
709 handler MAY set this to reflect the schema of the returned record.
711 New member 'display_term' in struct scan_entry. GFS now sets member entries
712 and allocates scan entries to be filled by user scan handler. In previous
713 version, entries member was allocated by the scan handler. That still works,
714 but the GFS will ignore member display_term - assuming it was NOT set by
715 the handler. The fact that the GFS now allocates the entries both allows
716 for new members and makes a scan handler easier to write.
718 Fix CQL lex buffer overflow.
720 SRW/SRU recordPacking. For SRW default recordPacking is string. For
721 SRU default recordPacking is string.
723 SRU protocol support for frontend server.
725 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
727 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
729 Added scan for the ZOOM shell (zoomsh).
733 * String Identifers for Schemas (Amendment 5).
734 http://lcweb.loc.gov/z3950/agency/amend/am5.html
735 Old definition for schema
736 Odr_oid *schema; /* OPT */
741 Z_InternationalString *uri;
742 #define Z_Schema_oid 1
743 #define Z_Schema_uri 2
746 * resultCount parameter to Sort Response (Amendment 1).
747 http://lcweb.loc.gov/z3950/agency/amend/am1.html
749 Support for SRW 1.0 over HTTP. This is an optional feature and
750 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
753 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
754 on the same port. SRW SearchRetrieveRequests are mapped
755 to bend_init,bend_search,bend_fetch,bend_close.
757 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
759 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
760 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
762 ZOOM connections are SRW based if schem http is used for hostname
763 in connect, e.g. z = ZOOM_connection_new("http://myserver");
764 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
766 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
767 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
768 distance=n, order=true/false, relation=le, prox unit=word. If
769 n is omitted, distance 1 is used.
771 Fixed problem with C compiler include path in wrong order.
773 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
774 on Solaris. Patch from Ko van der Sloot.
776 New MARC decode API. All new functions operate on a yaz_marc_t
777 handle. The most important new functions are: yaz_marc_create,
778 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
779 decode and destroy respectively. Decoder can produce formats
780 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
781 include/yaz/marcdisp.h.
783 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
784 to UTF-8, UCS-32, wchar_t or Latin-1.
786 * Prototypes for yaz_iconv_-functions moved to separate header
787 include/yaz/yaz-iconv.h.
789 Make a few private functions 'static' in unix.c. This prevents
790 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
792 For ZOOM connection, the options targetImplementation{Id,Name,Version}
793 are set when Init Response is received.
795 New function ZOOM_connection_error_x similar to ZOOM_connection_error
796 but returns diagnostic set as well.
798 New function yaz_strerror which is a portable wrapper for
799 strerror/strerror_r/GetLastMessage.
801 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
802 is returned for MARC. If type is "oai", then OAI MARC is returned.
804 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
809 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
811 Fix bad race conditions on SIGTERM and terminate gracefully in
814 Move retrieval (data1) module to Zebra since nobody seems to be
817 Add GRS-1 render for ZOOM using same format as yaz-client.
821 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
823 Fix broken ESpec handling in data1 module.
825 SGML reader parses comments and makes them part of the data1 tree.
827 Added several type casts so that YAZ compiles as C++ code.
829 ZOOM didn't handle PDU encoding failures properly.
831 Added more Bib-1 diagnostics (approved extensions).
833 GNU configure: better check for iconv.
835 More portable use of accept, getpeername. Check for socklen_t. Use
836 int/size_t if socklen_t is not defined.
840 PQF parser rejects bad queries - including those with extra
841 characters in them. PQF parser used to silently ignore that.
842 Cleaner API for PQF added, which allows you to get detailed
843 error information for bad queries (see yaz/pquery.h).
845 Fixed bug in ZOOM_record_get for type "database".
847 Implemented mini iconv library supporting conversions between
848 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
850 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
854 Fixed ZOOM C record cache so that preferredRecordSyntax and
855 elementSetName is used to check for already fetched records.
859 Added three members in bend_initrequest structure to facilitate
860 character set negotiation.
862 Fixed a bug in frontend server that could cause indefinite
863 loops under rare conditions.
865 Revised character set utilities (charneg.h) so that encoding
866 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
868 For PQF, directive @term <type> sets term type for Scan/Search.
869 Here <type> is general, string, numeric, null. The term type
870 is inherited - just like @attr.
872 New call odr_set_charset that sets character set conversion for
873 international-strings on a ODR stream. Prototype is:
874 int odr_set_charset(ODR o, const char *to, const char *from);
875 The InternationalString is still represented as C string in YAZ
876 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
877 won't). On the protocol level, you can use any encoding.
879 Support for UNIX sockets in ZOOM.
881 Solaris recv sometimes returns errno == ENOENT. It is treated as
882 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
884 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
885 both client and server. Code by Morten Bøgeskov.
889 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
890 that they can be used directly from Visual Basic. You must recompile
891 your windows APP if you're using ZOOM.
893 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
894 Commands "lang" and "charset" sets language and character set respectively.
895 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
896 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
898 Attributes from multiple CCL fields may be OR'ed rather than merged
899 using directive "@field or". Fields are still merged by default -
900 equivalent to "@field merge".
902 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
905 Fixed bug in zget for parameter ExtendedServicesResponse.
911 Added PQF feature: '@attr type=value' may be written as '@type=value'.
913 Client displays USR.1:SearchResult-1 (hits per term).
915 Additional Search Info for search in Generic Frontend Server.
917 Fixed CCL parsing of "field=s".
919 WIN32 installer - using the excellent NSIS software from nullsoft.
921 Fixed CCL parsing of "field = - <number>".
923 Added function yaz_marc_decode that decodes MARC for line mode
924 display or XML (similar to that used by JZKit).
926 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
927 Z39.50. But ISO/ILL was, however.
929 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
930 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
932 http://lcweb.loc.gov/z3950/agency/amend/am2.html
933 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
937 New YAZ client features: Command completion and new commands:
938 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
939 Code provided by Jacob Poulsen.
941 New call oid_trav, that visits all registered OIDs via callback.
943 Function ZOOM_record_get now returns const char pointer rather than
944 void pointer. It saves a lot of type casts.
946 For YAZ client, command "auth" now allows you to set authentication
947 in IdPass style. It is enabled when three tokens are given - order
948 is user, group and password.
950 Fix memory leaks in MARC record handling for ZOOM.
952 New option for YAZ client, -k <kilobytes> that sets
953 maximum record size. Similar to -k option for generic frontend
954 server and yaz-ztest.
956 More fixes for scan. Non-zero stepSize handled. OID's fixes.
958 Prefix query parser reports "fail" when bad attribute set is given.
960 Fix in MARC decoder. Proximity logging. Fix for attribute set
961 in scan handler for server. Patches by Shigeru Ishida.
963 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
966 Configure option --with-openssl=<dir> now works when a directory is
967 specified. Patch provided by Morten Bøgeskov.
969 New option for YAZ client, -u <auth>, that sets authentication.
971 ZOOM fix: error information was sometimes "missing", since error
972 was cleared/reset too when it shouldn't.
974 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
978 Scan for ZOOM API. New object ZOOM_scanset. New functions
979 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
980 ZOOM_scanset_destroy.
982 New ZOOM function, ZOOM_connection_last_event, that returns type
983 of last event (such as "receive data", "send data", "apdu received",
986 New ZOOM option, schema, that specifies schema for retrieval.
988 New CCL feature. Qualifiers can be aliases for one or more
989 other qualifiers (if more than one is given, OR is used).
991 ZOOM uses named result sets if target supports it.
993 Two new YAZ client commands: . (dot, which sources a script of YAZ
994 client commands), and ! (to execute shell command.). Implemented
997 Working on Debian packages.
1001 YAZ client enables named result sets only if target supports it.
1003 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1005 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1006 with key="host" to get same result.
1008 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1009 Function Z3950_resultset_record(s) returns references to records
1010 "owned" by resultset. To become owner use Z3950_record_clone.
1012 Function z_ext_record handles Extended Services. Thanks to
1015 --- 1.8.2 2001/11/12
1017 CCL Parser fix: ignore token comma when dealing with and-lists.
1019 Documentation updates for COMSTACK.
1021 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1022 Changed prototype Z3950_records. For some functions, int parameters
1023 were changed to size_t.
1025 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1028 New MARC decode/display function, marc_display_exl, which properly rejects
1029 non-ISO2709 records. YAZ client uses it.
1031 --- 1.8.1 2001/10/29
1033 Fix bug: local attribute set wasn't set correctly in PQF strings.
1037 * Old Z39.50 codecs no longer supported.
1039 Added ZOOM C binding. See http://zoom.z3950.org/
1041 Renamed states for COMSTACKs to avoid confusion with events.
1043 Implemented cs_look and proper cs_rcvconnect.
1045 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1047 Configure detects POSIX threads on OpenBSD.
1049 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1050 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1052 When error is returned from present handler, non-surrogate diagnostic
1053 is returned in present response (and fetch handler is no longer called).
1055 * Minor adjustments to pquery parser (PQF). Token characters may be
1056 escaped by using backslash (C-style).
1058 PQF parser allows string attribute values to be specified. For @attr,
1059 non-numeric characters after the equal-sign are treated as strings
1060 (e.g. @attr 9=title).
1062 CCL trunction character may be defined (@truncation in file)
1064 * function zget_ExtendedServicesRequest sets waitAction to
1065 waitIfPossible (was wait).
1067 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1070 CCL operator names may be set in field definition files (CCL_bibset).
1071 See ccl/bib1 for an example.
1073 Fixes in ASN.1 compiler for C++ compatibility.
1075 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1076 and "op_or" to avoid conflict with C++.
1078 Fixed problem with GNU readline detection on Redhat 7.0.
1080 Added step-size for Scan backend handler.
1082 Fixed bug that made the frontend server crash when no attribute
1083 set was specified for scan.
1085 Front-end server automatically switches to original working directory
1086 when installed as an NT service. Previously -w had to be specified to
1089 Added extended attributes for retrieval module (data1), so that data1
1090 records carry d1_readXML/SGML attributes. d1_read also supports
1091 null-data rules ( <tag/>)
1093 On UNIX when POSIX threads are available, a separate library libyazthread
1094 is created. Programmers should link with that library and the yaz library
1095 when using threads. The reason for the split was that some applications
1096 on Linux, such as Apache, doesn't work well when using shared objects that
1099 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1100 (or any frontend server) in SSL mode by specifying ssl: followed by
1101 address. Only tested on UNIX.
1103 Added feature for CCL module. Virtual structure s=al or s=ol generates
1104 and-list and or-list respectively instead of phrase search.
1108 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1109 log_mask_str. This was done to avoid name conflicts with other libraries
1110 (such as other PHP extensions).
1112 Added raw OID member for preferred record syntax (request_format_raw)
1113 and returned record syntax (output_format_raw) for backend fetch method.
1115 Config file yaz-config now accepts options so that it returns specific
1116 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1118 Shared library support for UNIX using GNU libtool.
1120 * Modified backend interface. Request/Response struct's replaced by
1121 one read/write C struct. For example bend_fetchrequest and
1122 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1123 Every handler - even search has to be registered in bend_init
1124 handler. This means that the YAZ library no longer refers to
1125 external functions and it makes it possible to make the whole
1126 thing a single DLL/SO.
1128 Added Segment handler for backend server.
1130 Added Zmbol/Zebra administrative functions to YAZ client.
1132 Threaded frontend server on UNIX (when POSIX Threads are available).
1133 Starting the server with option -T enables multi-threading.
1137 Added configure option --enable-comp/disable-comp to control use
1138 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1139 located in sub directory asn.
1141 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1142 in ${exec_prefix}/bin along with the other programs yaz-client and
1145 GNU automake used to maintain makefiles.
1147 Added several OID's.
1149 Changed retrieval module so that we can load records with no abstract
1150 syntax defined. Tagpaths in these records are fully composed of string
1153 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1157 On UNIX, the generated makefile now supports a proper 'make install'.
1158 The prefix can be set via GNU configure to set the install location
1159 (default is /usr/local).
1161 * YAZ programs client and ztest were renamed to yaz-client and
1162 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1163 locations, such as /usr/bin,/usr/local/bin,etc.
1165 * YAZ Header files were moved from include to include/yaz. YAZ Header
1166 files are referred to as include <yaz/log.h> rather than <log.h>.
1167 The YAZ include path (-I ..) is therefore the same as before. Programmers
1168 should update their #include statements or use -Ipath/include/yaz
1169 instead. The main motivation for doing this change is that YAZ header files
1170 can be installed in "standard" locations /usr/include,/usr/local/include
1171 without introducing conflicts, since ALL YAZ header files are stored
1172 in subdirectory yaz (under /usr/include for example).
1174 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1175 rather than project/workspace files. We switched because project files
1176 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1179 Changed name of logging function, logf, to yaz_log, to prevent name
1180 clash with some math-log functions. The YAZ header log.h defines logf
1181 to yaz_log (#define) so there should be no incompatibilities by this
1184 Added bend_start/bend_stop handlers for server. These handler are
1185 called on start/stop of server. For windows they are called whenever
1186 a service is started/stopped.
1188 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1189 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1190 in util/yc.tcl. The auto-generated C code structures are, in a few
1191 cases, incompatible with the old decoders. There are differences in the
1192 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1193 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1194 The preprocessor variable ASN_COMPILED is defined when the compiled
1195 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1196 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1197 wish to use the old encoders/decoders you can specify --disable-yc
1200 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1201 version so that it supports both new - and old version of DB Update
1203 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1204 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1205 change. The name parameter can be set to 0 in which no name is specified
1206 for the construction. The macros odr_implicit and odr_explicit sets name
1207 parameter to zero for the construction involved. New macros
1208 odr_implicit_tag and odr_explicit_tag are similar to the others,
1209 except that a name parameter is added. For programmers' that don't use
1210 ODR they probably only need to change the call to z_APDU and z_External.
1212 Added access control facility by interfacing the TCP wrapper library.
1213 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1214 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1215 name of the daemon and enables the access control as specified in
1216 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1218 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1219 den Dool <H.M.vdnDool@kub.nl>.
1221 Added reference ID parameter to most functions in server API - refer
1222 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1224 Changed name of ccl library to libccl.a (was ccl.a).
1226 Fixed bug in decoder for Explain (Category TargetInfo).
1228 Added support for GNU readline in client. Thanks to Jacob Poulsen
1229 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1231 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1232 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1233 IMPLEMENTATION! This change was made to the development version before
1234 the ZIG decided to retract the amendment. If any users MUST be
1235 compatible with the original Update definition, PLEASE CONTACT US, and
1236 we will include a separate definition corresponding to the old Update
1237 ES. Note that because of the change to the ASN.1 of the
1238 TaskPackageRecordStructure we cannot define a single structure that
1239 will support both versions.
1241 * Added const modifier to buffer parameter for some ODR/BER encoding
1242 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1243 completeWAIS, odr_dumpBER.
1245 Fixed bug in client.c which caused a crash when a scanResponse didn't
1246 contain positionOfTerm.
1248 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1249 * will cause an error in a client if a non-YAZ target sends both a
1250 * list of Scan entries and non-surrogate diagnostics.
1252 Retrieval module enhancements. Tag sets may be typed in the reference
1253 to it. From the .abs-file the "tagset" directive takes a third optional
1254 integer type for the tag set referenced. From a .tag-file the "include"
1255 directive takes a third optional type as well. The old "type" directive
1256 in the tag set itself is still recognized but acts as the default type
1259 Backend interface change. Individual Scan terms returned from bend_scan
1260 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1261 in include/backend.h.
1263 Retrieval module enhancements. Multiple tag sets and attribute sets may
1264 be specified in abstract syntax specs. Revised the error/warning for
1265 logging messages reported by the retrieval module when reading the
1268 Object Identifier system (oid_..) changed. The API is backwards
1269 compatible but the oid-routines now allocates new OID's when needed.
1270 Raw OID's may be specified in oid_getvalbyname.
1272 YAZ now uses GNU configure to generate Makefile(s).
1274 * Minor changes in some of the member names of DeleteResultSetRequest and
1275 DeleteResultSetResponse. See include/proto.h.
1277 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1278 and added member 'languages' in TargetInfo (which was missing).
1280 Changed the way attribute sets are handled in the retrieval
1281 module. These are now cached, just like the abstract syntaxes
1284 Changed YAZ so that it links with compiled ASN.1.
1286 Added Explain-schema definitions and mapping routines. The following
1287 Explain categories have been implemented: AttributeDetails,
1288 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1290 Fixed minor bug in Windows version of Server Library.
1292 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1294 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1296 Added EXTERNAL: UNIverse Resource Report (non-standard).
1298 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1299 ENUMERATED and SET OF.
1301 * Added 'const' to some of the char pointer arguments for the
1302 functions, data1_read_node, data1_getelementbytagname,
1303 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1306 Fixed bug in data1_insert_taggeddata - the last_child member of
1307 parent wasn't initialised.
1309 * Changed data1_read_record and data1_read_node so that the supplied
1310 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1311 doesn't refer to any parts of the "SGML"-buffer.
1313 Fixed bug in server library (Windows version of statserv_remove).
1315 * Changed code so that it compiles as C++. The type definition
1316 of Odr_fun which is a member of Odr_arm was changed. The result is,
1317 that an explicit typecast is needed for the fun pointer when
1318 using Odr_arm - as in:
1319 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1321 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1323 Implemented the new structured date and time definition as approved
1324 by the ZIG. Added schemaId element to the specificTag in Espec-1
1325 (also approved at the last ZIG). Thanks to RVDM.
1327 Added some Object identifiers (RVDM).
1329 Changed the Update Extended Service (RVDM).
1331 Added command "refid" to client which specifies referenceId for
1332 the following requests.
1334 Implemented extended service handling for server. See ztest.c
1335 for an example as well as backend.h. New handlers are registerd
1336 in the Init handler.
1338 * Changed interface for sort in server.
1340 Added new members to statserv_options_block. It allows a server
1341 to read options from another source than just the command line. Thanks
1342 to Charles Woodfield.
1344 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1345 renamed to zboolean. Some C++ compilers complained about the name.
1347 Minor changes to gils.abs. Added index 's' (sort) on title
1348 and date/time-last-modified.
1350 --- 1.4pl2 1998/1/30
1352 Fixed bug in server library regarding inetd mode (-i). This bug
1353 was introduced by release 1.4.
1355 --- 1.4pl1 1998/1/29
1357 Added sort facility in client and backend server interface.
1359 Fixed problem with dependencies in Makefile(s).
1361 Fixed bugs for encoders/decoders of extended services and
1364 Implemented sub-tree feature for schemas. Sub-trees are
1365 referenced in *.abs-files. See explain.abs for an example
1366 of the use of this feature.
1368 Modified bib1.att; local attributes for ANY didn't include
1369 ANY itself (only affects use of the retrieval module).
1371 Fixed bug in plain SGML reader in function data1_read_node:
1372 tags with prefix "var" was incorrectly interpreted as variants.
1374 Added feature "sub-schemas" to enable references to - and definitions
1375 of - group of elements.
1377 * Removed member parent from type data1_element (in data1.h).
1379 Implemented function odr_nullval() that returns the value of
1382 * Removed member num_children from data1_node (in data1.h).
1384 Made NT service interface part of the server library. The
1385 function statserv_main uses the NT service when required and
1386 calls the statserv_start / statserv_close routines.
1388 Routine zget_SearchRequest and zget_PresentRequest fills
1389 resultSetName/Id member with "default" instead of "Default".
1391 Fixed memory leak in server. Request queue member wasn't freed.
1393 Fixed nmem_exit so that memory is freed.
1397 Revised the CCL parser utility to be thread safe.
1399 Added function, oid_ent_to_oid, to replace the function
1400 oid_getoidbyent, which is not thread safe.
1402 * Added nmem_init and nmem_exit to initialize and release
1403 NMEM resources. Function nmem_init should be called once in the
1404 initial thread before NMEM/ODR is used. statserv.c and client.c
1405 have been changed accordingly. The change was necessary to make
1406 NMEM thread safe. The NMEM memory pool is shared amongst threads
1407 in a process. Unix-based applications will still work fine without
1410 Added NT Services interface for the the Z39.50 (statserv) Server.
1411 Refer to the ztest.c source on the usage.
1413 Windows 95/NT port using MSVC5.0. Project files are included in the
1416 * Defined new 'global' handle for the retrieval (data1) system. The
1417 new handled, data1_handle, describes the state of the data1 system.
1418 This handle is passed as first argument to virtually all
1419 data1 related routines. The functions data1_create and data1_destroy
1420 creates and destroys a data1 handle respectively.
1422 Added ODR encode stream member to all backend request structures
1423 init, search, scan etc. This stream should be used to allocate all
1424 memory used for the response when thread safe operation is needed.
1426 Changed the comstack utility, cs_addstr, to be thread safe. The
1427 returned hostname string returned by the function is now part the
1430 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1431 function. The cs_straddr takes a COMSTACK handle as argument, so this
1432 function must be used after cs_create and before bind/connect.
1433 This function is thread safe.
1435 Moved test server to 'ztest' directory - generic server code still
1436 in 'server' directory.
1438 Made prefix query (pquery.c) utility thread safe.
1440 Added new function modifier YAZ_EXPORT to 'export' public DLL
1441 functions when using windows (see include/yconfig.h).
1443 Added definitions to the OID database (util/oid.c) (RVDM).
1445 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1447 Added call to ccl_rpn_delete in client program.
1449 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1450 release of RPN structure.
1452 Added support for C++, headers uses extern "C" for public definitions.
1453 With input from RVDM.
1455 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1456 Thanks to Ronald van der Meer (RVDM).
1458 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1460 Added support for private extensions to the OID database
1461 (oid_setprivateoids()). Thanks to RVDM.
1463 Added optional, physical ANY (key replication)
1465 Fixed null-reference problem in GRS-1 output filter.
1467 Proximity operator added to Prefix Query Format (PQF).
1469 In test client command "base" accepts multiple databases.
1471 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1475 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1477 Smallish bug-fixes in the new encoders/decoders (explain).
1479 Bug fixed in DeleteRequest.
1481 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1483 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1485 Added SOIF syntax (using private OID for now) to retrieval module and client.
1487 Added Update extended service.
1489 Added SearchResult-1 additional info structure.
1491 Added optional CCL (ISO8777) interpreter as separate module. Available
1494 --- 1.2 1996/6/10 (1st anniversary release)
1496 Added Summary record syntax. Lightly tested.
1498 Added OPAC record syntax. Untested.
1500 Added ResourceReport service encoders/decoders. Untested.
1502 Fixed bug in z_Unit - wrong tagging on unitSystem.
1504 Fixed bug in the DiagRecs decoder.
1506 Added options for max PDU size and session timeout to frontend-server.
1508 Added documentation of query-language parsers and other supporting utilities.
1510 [frontend-server] Added Attribute set to the bend_scanrequest API.
1512 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1513 surrogate diagnostics were generated.
1515 [retrieval] Allow multiple local values for attribute.
1517 [retrieval] Allow multiple attributes per element in .abs files. index type.
1519 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1521 --- 1.1pl2 1996/4/10
1523 Minor changes, mostly specific to Zebra's requirements (retrieval)
1527 Repaired bug in frontend server when running multiple listening
1528 endpoints in dynamic mode.
1530 z_External() now won't break if a known, ASN.1 value comes encapsulated
1531 in an octet-string. The value will pass through unmodified in an Odr_oct.
1533 Added a bit of code to the demo client to decode & display
1534 ASN.1-structured records represented in the octet-aligned branch of
1535 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1537 Added z_ext_getentbyref() to the ASN module. Doc updated.
1539 * Completed the SCAN definition in the ASN module. This may break SCAN
1540 code based on older YAZ-versions at compile-time. The fix is easy -
1543 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1544 under the SCAN definition. Remember to initialize this, server-people.
1546 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1547 that this does not extend to ODR and ASN.
1549 Comstack allows insertion of established socket (primarily for
1550 inetd-operation of servers). Doc updated.
1552 Front-end server can now start from the inetd in TCP mode. Doc
1555 --- 1.0pl4 1996/1/24
1559 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1560 the rank and record number.
1562 Adjustments to the frontend server.
1564 Fixed diagnostic BER dumper. It ignored the file argument.
1568 Various changes to retrieval module.
1570 Changed the union discriminators of the protocol files from enums to
1571 ints paired with #defines.
1573 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1576 *Changed operator in the RPN structure to 'roperator', again to avoid a
1579 Fixed problems in Explain decoders/encoders.
1581 --- 1.0pl2 1995/12/6
1583 Memory bug in log module fixed.
1585 --- 1.0pl1 1995/12/5
1587 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1589 Bug in Explain DatabaseInfo module fixed.
1591 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1595 The shift to v1.0 signals that we now consider the *core* functionality
1596 of YAZ reasonably stable (the core being more or less equivalent to
1597 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1598 tested (Explain not at all - though that will happen soonish).
1600 Minor changes to code to support Windows port.
1602 Various minor changes after we're getting to use GRS-1 & co. more.
1604 Added Espec-1 format.
1606 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1607 of the protocol and it cannot be selected when encoding (maps into 'string'
1608 when decoding). Needed to talk to some servers.
1610 Demo client can request simple element set names.
1612 Added Diagnostic Format encoders/decoders.
1614 Added simple Close handling to frontend server (no hooks for resource
1615 reporting yet), and demonstration client.
1617 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1619 --- 1.0b3 1995/08/24
1621 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1622 handled incorrectly when records were requested in the searchResponse. This
1623 will only affect you if you use the frontend-server.
1625 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1626 Test-client will ask for and print GRS1. Ztest will return dummy records
1629 Added Explain encoders/decoders to the service-level API. Untested.
1631 Added Extended Services: Item Order encoders and decoders to the Service-
1632 level API. Untested. We could use a recent copy of the pertinent bits
1633 of the ILL protocol to add those bits.
1635 Added diagnostic format 1 encoders/decoders to the service-level API.
1638 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1639 odr_cons.c, which causes a more correct output.
1641 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1642 was always set to 0 when no records were requested in the searchRequest.
1644 * Added better external-handling. This shouldn't harm old code that
1645 *encodes* externals. It can break code that looks for a
1646 'single-ASN1-type' representation, since those types that are known
1647 are now decoded immediately. Look at the SUTRS sample code in
1648 seshigh.c and client.c. Documentation updated.
1650 Handling of structured records in bend_fetchresponse. Length -1 marks
1651 structured record, type is deduced from format field.
1653 --- 1.0b2 1995/06/27
1654 Fairly quick maintenance release to add SUTRS support.
1656 Fixed handling of SUTRS records in the demonstration client.
1658 * Added format field to the bend_fetchrequest and bend_fetchresponce
1659 structures of the backend API (frontend server). When the record is
1660 returned, the value of the format field is mapped to an OID. The
1661 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1662 of the record. The special value VAL_NONE in the bend_request means
1663 that no specific format was requested by the client. Documentation
1664 updated accordingly. Test server (ztest) will return a fixed dummy
1665 SUTRS record if your client requests SUTRS.
1667 Documentation updated accordingly.
1669 You can now set external libraries and RANLIB support in the top-level
1673 First public release.
