2 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
3 sequences where not read correctly. Fix by Rustam Usmanov.
5 Updates to win/makefile which makes things compile happily with VS C 2005.
9 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
11 In ZOOM socket code, use select instead of poll on MacOSX.
13 ZOOM-C now support client-side compilation of CQL into RPN that is
14 sent to the server, enabling CQL to be used against all Z39.50
15 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
16 ZOOM_query object, and submit it using ZOOM_connection_search().
17 The CQL-to-RPN translation uses a configuration file, the name of
18 which must be specified in the Connection's "cqlfile" option.
20 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
21 function, which takes as its start-term parameter a ZOOM_query object
22 (which may have had either CQL or RPN set into it).
27 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
28 GFS to support this as well. Backend handler, bend_srw_update, does the
29 update work. Code contributed by Ko van der Sloot.
31 Allow retrieval of Search Result-1 information in ZOOM by the use of
32 options that are attached to a result set. ZOOM documentation updated
35 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
36 UTF-8 conversion. Patch by Raj Patel.
38 Added option -m to GFS to control formatting of timestamps in log file.
40 Added 'exit' as synonym for 'quit' in yaz-client
42 Added support for specifying SRW resultSetId + resultSetIdleTime in a
43 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
44 for the new members. Patch by Ko van der Sloot.
46 Added support for SRU POST. It is supported for content-type
47 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
49 Do not build the separate Multi-threaded (MT) library libyazthread.la.
50 Instead make the library libyaz.la multi-threaded. Threading as a whole
51 can still be disabled by configure option --disable-threads. Previosly,
52 with older GLIBCs there were problems with MT libs under Apache. This
53 has now been fixed a long time ago.
55 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
58 CQL module modified to be case insensitive for relations/indexes/operations.
60 Fixed bug in CQL transform code: incorrect value relationModifieder
63 Added 'show all' command for yaz-client which retrieves all results
66 Added new yaz-client, xmles, which takes a (private) OID and
67 a document to be sent as an extended service request.
69 Describe new yaz-client commands wait_response and set_auto_wait.
71 Increase TCP/IP listener backlog from 3 (which I am guessing was
72 copied from the SunOS manual entry way back when) so SOMAXCONN, so
73 that the socket will queue as many incoming connections as it's able
74 to handle ongoing connections. In other words, it will never now
75 refuse a connection that it would be able to handle merely because
76 it's not got around to accepting() enough of the pending connections
77 yet. This is the behaviour anyway under Linux, where the listen()
78 argument is ignored; but not under BSD and on systems such as
79 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
80 YAZ-based servers should now be uniform across operating systems in
83 yaz-marcdump uses 64-bit file access on some systems. This is enabled
84 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
85 This allows yaz-marcdump to read large MARC batches (>2 GB).
87 Modified all YAZ source files - except the source which is auto-generated
88 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
91 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
92 corresponding to the existing *_setl() function. These allow option
93 values containing arbitrary valuues.
95 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
96 ZOOM_resultset_sort() in new applications. Its behaviour is identical
97 except that it returns an indicator of whether or not the sort
98 criterion was accepted (0 for OK, -1 for invalid).
102 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
103 MARC output rather than returning "new" buffer.
105 yaz-client warns about unknown init options.
107 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
111 Added support for SRW sort in Generic Frontend Server. Patch
112 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
113 sortKeys - or NULL if none is provided.
115 Fixed bug #307: It was impossible to specify indefinite/no timeout
116 for ZOOM_event. Special timeout value -1 now means indefinite timeout
119 Added support for multiple languages and charsets to be specified in
120 ZOOM. Each charset/language is separated by a blank. If negotiation is
121 in effect in init-response, Option
122 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
123 Code based on patch by Vasiliy Osadchuk.
125 Fixed bug #306: infinite recursion that occurred when calling
126 yaz_log_level_init as the first call (before other log level or
129 Fixed bug in scan handling in front end server: if preferred-Position-In-
130 Response was non-present, a NULL pointer referece was performed.
134 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
135 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
136 now defined for all those error codes. So instead of putting 109 in
137 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
138 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
140 Modified the yaz-marcdump utility to skip garbage bytes between MARC
143 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
145 Program yaz-client now exits and produces an error message if multiple
146 Z39.50 servers are specified on the command line (none or one allowed
149 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
154 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
156 Fixed bug #272: Preserve spacing for CCL terms.
160 Added support for virtual hosts and multiple backend servers for
161 the YAZ frontend server. The configution is XML based and
162 support specificition of CQL to RPN mappings and explain information.
163 See section "Virtual Hosts" in the YAZ manual.
165 Extended OPAC display utility. OPAC display utility renders
166 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
167 to supplement yaz_marc_decode_wrbuf.
169 Fixed a bug in MARC decoder that could caused it to crash for some
170 invalid MARC records. More diagnostics and warnings where added in
171 XML output (warnings, etc are stored in comments).
173 --- 2.0.34 2005/02/08
175 Fixes for UNIX domain sockets. Bug #261.
177 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
179 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
180 Added yaz_marc_subfield_str which defines subfield lead string which is
181 used in YAZ_MARC_LINE format. Default string is blank+$. Added
182 yaz_marc_endline_str which defines end of fields string used in
183 YAZ_MARC_LINE format. Default string is newline.
185 Experimental support for MarcXChange. This format can be produced
186 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
187 http://www.bs.dk/standards/MarcXchange.xsd
189 Added yaz-client commands scansize that sets maximum number of
190 entries to be returned by scan.
192 --- 2.0.32 2005/01/11
194 Added support for SRW scan in yaz-client and Generic Frontend Server.
196 * Added whereInList member to SRW Scan Term.
198 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
200 Fixed NMEM system to return aligned blocks on the smallest boundaries
201 that are suitably aligned for all possible types on the particular
202 architecture YAZ is being built for.
204 --- 2.0.30 2005/01/04
206 Fixed numerious warnings that was issued with newer versions of GCC.
208 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
209 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
212 Make YAZ Generic Frontend Server slightly faster.
214 Enhance (and reduce) logging for Generic Frontend Server.
216 Revert YAZ log system so that it flushes every write operation
217 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
219 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
220 instead of LOG_, due to name clash with syslog(3). LOG_ are still
221 present. New applications should define YAZ_USE_NEW_LOG=1 - this
222 will effectively disable old definitions.
224 --- 2.0.28 2004/11/09
226 Added yaz_log_time_format which specifies log format using
229 Added yaz_log_module_level which returns mask for a module. Value
230 is non-zero mask a if module is enabled; zero if disabled.
232 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
233 in include/yaz/cql.h.
235 Fixed bug #176: Dont throw diagnostics on empty SRU args.
237 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
239 Fixed bug #172: RPM builds does not enable SSL.
241 Doxyfile.in part of dist. Doxyfile generated by configure.
243 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
244 are given and the corresponding component does not exist.
246 Extend CCL documentation in YAZ reference. Describe r=r.
248 --- 2.0.26 2004/10/01
250 Fixed MARC->MARCXML conversion to properly deal with
251 fields, subfields, indicators having non-ASCII characters.
253 Fixed MARC->MARCXML conversion so that ASCII control characters
254 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
257 Added YAZ GFS support for conversion from Z39.50 surrogate
258 diagnostics to SRW surrogate diagnostics.
260 Bug fix: YAZ GFS did not return schema in explainResponse.
262 --- 2.0.25 2004/09/30
264 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
265 now converts recordSchema to elementSetName as well as schema URI.
267 Fixed bug in COMSTACK that prevented HTTP request packages from being
270 --- 2.0.24 2004/09/29
272 Added CCL facility r=r "range" which is similar to r=o "ordered" but
273 does not require white-space before and after the dash in a range, e.g.
274 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
277 Fixed a few AC_TRY_LINK configure tests that did not operate properly
278 due to new GCC removing "redundant" code.
280 Added yaz-client commands scanpos and scanstep that sets preferred
281 position and step-size for scan.
283 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
285 Added CCL utility ccl_qual_buf which parses one or more CCL
286 spec lines in a buffer.
288 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
289 of name and value - ignoring empty lines and comments.
291 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
293 Added odr_get_element_path which returns current element path for an
294 ODR handle. This utility is useful in error handling or user-defined
297 Added ODR_PRINT utility odr_set_stream which is is a more generic
298 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
299 to a write function and pointer to close function. The close function - if
300 non-NULL - will be called during odr_destroy.
302 Fixed bug in CCL parser where truncation char was not removed from
303 right side when truncation=both was in effect.
305 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
308 --- 2.0.23 2004/08/11
310 Fix buffer overrun in CQL parser when dealing with proximity (%).
312 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
313 to UTF-8/UCS conversion is now only based on codetables.xml.
315 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
317 --- 2.0.22 2004/08/06
319 Add support for more "commit changes" in ZOOM (uses Extended Services).
321 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
324 Yet another small fix for configure of SSL.
326 --- 2.0.21 2004/05/14
328 Fix SSL libs for configure when --with-openssl=DIR is given.
330 --- 2.0.20 2004/05/10
332 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
334 SSL comstack now uses yaz.pem certificate file on server side
335 by default. Certificate filename can be configured by calling
336 comstack function cs_set_ssl_certificate_file before cs_bind is used.
338 Fix bug regarding multiple calls to ZOOM_connection_connect.
340 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
342 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
343 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
345 ZOOM now allows inspection of X509 peer certificate for verification.
346 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
348 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
349 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
350 as "modular" but it simplifies things.
352 Added cs_get_peer_certificate to that returns peer X509 PEM.
354 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
355 NULL if SSL is unavailable.
357 Documentation about MARC decoding tools.
359 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
361 --- 2.0.19 2004/03/30
363 Rename CHANGELOG to NEWS to follow GNU style packing.
365 Fix bug with missing initialization of member in init_diagnostics.
366 This bug affects threaded version of GFS server.
368 --- 2.0.18 2004/03/20
370 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
373 Ensure zlib.dll is packed with Windows install.
375 --- 2.0.17 2004/03/17
377 Fix encoding of xsd:string to use text instead of CDATA.
379 Fix endless loop in CQL parser with unbalanced ".
381 Use a more compact way to store MARC-8 conversion tables.
383 --- 2.0.16 2004/03/16 Debian only
385 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
388 Update CQL parser to use new CQL 1.1 modifiers for booleans and
393 --- 2.0.15 2004/03/01
395 Another fix for decoding of XML packed records.
397 --- 2.0.14 2004/02/25
399 Fixes for Chunked encoding. White space not ignored after length spec.
401 Update NS and use default NS for SRW diagnostic elements.
403 --- 2.0.13 2004/02/23
405 Implement ZOOM_resultset_cache_reset which resets record cache.
407 Implement ZOOM_resultset_sort which sorts a result set.
409 Implement chunked HTTP transfer.
411 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
413 --- 2.0.12 2004/02/16
415 Added member 'schema' to bend_explain_rr structure so that backend
416 can specify explain record identifier. Defaults to Zeerex 2.0.
418 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
420 --- 2.0.11 2004/02/16
422 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
425 Added init command for yaz-client which sends "extra" init request.
427 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
428 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
430 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
432 Make ZOOM error code for "invalid query".
434 Fixed compilation for SSL which wasn't properly enabled for all platforms.
436 --- 2.0.10 2004/02/05
438 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
441 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
443 Added option -p <file> to make Generic Frontend Server to write PID file.
445 Added option -D to put Generic Frontend Server in background on its own.
447 Make ZOOM C recognize option "password". If unset, "pass" is used
448 (for backwards compatibility).
450 Fixed a bug in Generic Frontend Server that could make it crash if a
451 client sets characterSetNegotation bit, but didn't pass negotiation stuff
454 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
455 Must be issued before open, in order to be in effect.
457 --- 2.0.9-6 2004/01/12 Debian/Windows
459 Make the SRU server more picky WRT unknown params, etc.
461 Bug fix: ZOOM scan response didn't return displayTerm - when present.
463 New YAZ client command, options, that sets Z39.50 options.
465 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
466 options from a string of tokens (one token for each option bit).
468 Update SRW diagnostic code messages.
470 --- 2.0.9-5 2004/01/07 Debian/Windows
472 Handle user defined stylesheet for SRW/SRU.
474 --- 2.0.9-4 2004/01/06 Debian/Windows
476 Fix bug in decoding of Content-Length.
478 --- 2.0.9-3 2004/01/06 Debian/Windows
480 Fix a bug with decoding of XML packed records.
482 --- 2.0.9-2 2004/01/05 Debian only
484 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
486 Fix bug in SRW/SRU diagnostics decoding.
490 Fixed bug in Generic Frontend Server which could drop records exceeding
491 preferred message size. Reported and fixed by Irina Dijour.
493 Fixed calculation of package size for structured records in Generic
494 Frontend Server. Reported and fixed by Irina Dijour.
496 Fixed namespace for SRW/SRU diagnostics.
498 Fixed SEGV in yaz-client that occured for HTTP connection errors.
502 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
503 this version is incompatible with version 1.0 and older YAZ SRW/SRU
506 CQL changes to reflect recent changes to the specification:
507 * Documentation talks about context sets instead of index sets.
508 * Documentation talks about indexes instead of qualifiers.
509 * The CQL-to-PQF transformer's configuration file now uses
510 "index.set.name = <attributes>" instead of the old form
511 "qualifier.set.name = <attributes>". (Both forms are still
512 understood but the latter is deprecated.)
513 * CQL terms with no explicit index specified are now interpreted as
514 cql.serverChoice instead of srw.serverChoice (which of course
515 behaves exactly the same.)
519 MARC conversion can now generate ISO2709 output in another
520 character set. yaz-marcdump uses this facility if you invoke it
523 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
524 functions from there can be used from C++.
528 Frontend server now transfers memory from decoded packages to stream
531 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
532 references to show up.
534 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
535 the ZOOM Abstract API. The older names for the same options are still
536 also supported for the benefit of old applications.
538 ZOOM-C supports "implementationId" and "implementationVersion" options
539 to go along with "implementationName". These allow the user code to
540 specify identification strings to be sent to servers.
541 Add OID for the new ExtLite attribute set.
543 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
544 as requested/supplid by Ere Maijala <ere@atp.fi>
546 For generic frontend server, reverse the order of
547 "toolkit-supplied / application-supplied" strings sent as implementationId,
548 Name and Version. Also, remove the spaces around the slash. This brings
549 the GFS in line with the behaviour of ZOOM-C on the client side.
551 Add function ZOOM_scanset_display_term.
553 yaz-client shows scan displayTerm if present.
555 Utility yaz-iconv is now installed by default along with the man page
558 Extend configure check for OpenSSL to use pkg-config where available (such
561 Incorporate patch by Morten Bogeskov which allows a Unix file socket
562 server to specify uid/gid/mask for socket using the format
563 unix:[user=uid,][group=gid,][umask=mask,]file=path
564 If file= is omitted the existing format is assumed, e.g.
566 in which case the mask is 0666 (rw for everybody).
568 Major restructure of YAZ source. All source in libyaz is in src directory.
569 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
570 util (utility programs such as ASN.1 compiler, yaz-marcdump).
572 Added man page for utility yaz-marcdump (used to be called marcdump).
573 yaz-marcdump is installed by 'make install'.
575 Fixed a memory leak in Generic Frontend Server that occurred when decoding
576 of incoming package failed.
578 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
580 Change prototype of odr_perror: add const to message string.
582 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
584 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
585 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
586 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
587 DNS lookup. There should not be any compatibility problems with this
588 assuming that blocking=1 or 0 is used.
590 Fix bad reference in UNIX comstack in function cs_addrstr.
592 Fix for compilation on AIX.
594 The generic front-end server (server/seshigh.c) now supports returning
595 Init diagnostics to the client in User-information-field, in
596 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
601 Allow any CQL relation (not just all,any,exact,scr).
603 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
604 that features the same UI.
606 Implemented command update0 in YAZ client which is equivalent to
607 update but uses old of Ext Update ASN.1.
609 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
610 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
611 Previously no OID was used for this info.
613 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
614 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
615 returns 'malformed search term' otherwise.
617 SortResponse member resultCount now set to NULL in sort handler of
620 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
623 Add three new utility functions for translating OIDs between various
624 formats -- symbolic name such as "Usmarc", minus-1-terminated int
625 arrays and dotted strings such as "1.2.840.10003.9.5.1":
626 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
627 char *oid_to_dotstring(const int *oid, char *oidbuf);
628 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
630 Reverted modifications for ES Update definition for z_IU0Update
631 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
632 is back to YAZ 2.0.2.
634 String value attributes for CCL parser.
636 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
637 which their FirstSearch server returns in Init responses, sometimes
638 carrying useful diagnostic information when Init fails. This has the
639 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
640 "z39.50/oclcui.asn", where its definition is somewhat different from
641 what OCLC document on their web-site, as required to interoperate with
644 Support for anonymous authentication in yaz-client. Use the command
647 * Fix the OID of the Index Data-local "admin" Extended Service from
648 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
649 the 1000, which indicates a locally-defined OID, was a mistake.
653 Fix CCL directive @case handling so that it affects string match for
654 both CCL keywords and qualifiers.
656 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
657 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
658 Decoder has been updated with ASN.1 changes as listed in
659 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
660 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
661 z_IUUpdate, remains unchanged.
663 ZOOM_record_get may now return a record in a specific character set.
664 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
665 "from" is the character set of record as returned by target. "to" is
666 the character set to be returned. If omitted, "to" is UTF-8.
668 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
670 New ODR utility, odr_getelement, which returns name of element for
671 which encoding/decoding failed.
673 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
674 in cases where a required element was omitted.
676 Bug fix: some MARC8 sequences were not converted.
678 New ZOOM option "step" which specifies number of records to be
679 retrieved in one chunk. Used in conjunction with "start" and "count".
681 SRW support for yaz-client. Use scheme http: to use it, e.g.
684 yaz-client no longer does (un)intelligent character set conversions
685 by default. Can be enabled with charset and marc_charset commands.
687 xmalloc trace fix for 64-bit systems such as DEC alpha.
689 Solaris 2.6 compile fix.
691 New function, cql_strerror() translates SRW error codes, as returned
692 by cql_transform_error(), into human-readable English strings. Used
693 in yaz-client diagnostics when appropriate.
695 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
696 converts it into a type-1 query which is sent to the server. This
697 makes CQL available for use with all Z-servers, as opposed to the tiny
698 minority that can handle CQL queries themselves.
702 New Debian package layout similar to the Redhat Package layout.
704 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
705 and search result respectively.
709 Redhat package is now several packages: libyaz (runtime libraries),
710 libyaz-devel (development and documentation, and yaz (utility programs).
711 Package spec file by Morten Bøgeskov.
713 New member 'schema' in struct bend_fetch_rr which the name of requested
714 schema (SRW/SRU) for record (or NULL if none was given). The fetch
715 handler MAY set this to reflect the schema of the returned record.
717 New member 'display_term' in struct scan_entry. GFS now sets member entries
718 and allocates scan entries to be filled by user scan handler. In previous
719 version, entries member was allocated by the scan handler. That still works,
720 but the GFS will ignore member display_term - assuming it was NOT set by
721 the handler. The fact that the GFS now allocates the entries both allows
722 for new members and makes a scan handler easier to write.
724 Fix CQL lex buffer overflow.
726 SRW/SRU recordPacking. For SRW default recordPacking is string. For
727 SRU default recordPacking is string.
729 SRU protocol support for frontend server.
731 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
733 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
735 Added scan for the ZOOM shell (zoomsh).
739 * String Identifers for Schemas (Amendment 5).
740 http://lcweb.loc.gov/z3950/agency/amend/am5.html
741 Old definition for schema
742 Odr_oid *schema; /* OPT */
747 Z_InternationalString *uri;
748 #define Z_Schema_oid 1
749 #define Z_Schema_uri 2
752 * resultCount parameter to Sort Response (Amendment 1).
753 http://lcweb.loc.gov/z3950/agency/amend/am1.html
755 Support for SRW 1.0 over HTTP. This is an optional feature and
756 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
759 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
760 on the same port. SRW SearchRetrieveRequests are mapped
761 to bend_init,bend_search,bend_fetch,bend_close.
763 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
765 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
766 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
768 ZOOM connections are SRW based if schem http is used for hostname
769 in connect, e.g. z = ZOOM_connection_new("http://myserver");
770 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
772 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
773 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
774 distance=n, order=true/false, relation=le, prox unit=word. If
775 n is omitted, distance 1 is used.
777 Fixed problem with C compiler include path in wrong order.
779 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
780 on Solaris. Patch from Ko van der Sloot.
782 New MARC decode API. All new functions operate on a yaz_marc_t
783 handle. The most important new functions are: yaz_marc_create,
784 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
785 decode and destroy respectively. Decoder can produce formats
786 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
787 include/yaz/marcdisp.h.
789 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
790 to UTF-8, UCS-32, wchar_t or Latin-1.
792 * Prototypes for yaz_iconv_-functions moved to separate header
793 include/yaz/yaz-iconv.h.
795 Make a few private functions 'static' in unix.c. This prevents
796 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
798 For ZOOM connection, the options targetImplementation{Id,Name,Version}
799 are set when Init Response is received.
801 New function ZOOM_connection_error_x similar to ZOOM_connection_error
802 but returns diagnostic set as well.
804 New function yaz_strerror which is a portable wrapper for
805 strerror/strerror_r/GetLastMessage.
807 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
808 is returned for MARC. If type is "oai", then OAI MARC is returned.
810 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
815 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
817 Fix bad race conditions on SIGTERM and terminate gracefully in
820 Move retrieval (data1) module to Zebra since nobody seems to be
823 Add GRS-1 render for ZOOM using same format as yaz-client.
827 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
829 Fix broken ESpec handling in data1 module.
831 SGML reader parses comments and makes them part of the data1 tree.
833 Added several type casts so that YAZ compiles as C++ code.
835 ZOOM didn't handle PDU encoding failures properly.
837 Added more Bib-1 diagnostics (approved extensions).
839 GNU configure: better check for iconv.
841 More portable use of accept, getpeername. Check for socklen_t. Use
842 int/size_t if socklen_t is not defined.
846 PQF parser rejects bad queries - including those with extra
847 characters in them. PQF parser used to silently ignore that.
848 Cleaner API for PQF added, which allows you to get detailed
849 error information for bad queries (see yaz/pquery.h).
851 Fixed bug in ZOOM_record_get for type "database".
853 Implemented mini iconv library supporting conversions between
854 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
856 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
860 Fixed ZOOM C record cache so that preferredRecordSyntax and
861 elementSetName is used to check for already fetched records.
865 Added three members in bend_initrequest structure to facilitate
866 character set negotiation.
868 Fixed a bug in frontend server that could cause indefinite
869 loops under rare conditions.
871 Revised character set utilities (charneg.h) so that encoding
872 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
874 For PQF, directive @term <type> sets term type for Scan/Search.
875 Here <type> is general, string, numeric, null. The term type
876 is inherited - just like @attr.
878 New call odr_set_charset that sets character set conversion for
879 international-strings on a ODR stream. Prototype is:
880 int odr_set_charset(ODR o, const char *to, const char *from);
881 The InternationalString is still represented as C string in YAZ
882 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
883 won't). On the protocol level, you can use any encoding.
885 Support for UNIX sockets in ZOOM.
887 Solaris recv sometimes returns errno == ENOENT. It is treated as
888 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
890 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
891 both client and server. Code by Morten Bøgeskov.
895 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
896 that they can be used directly from Visual Basic. You must recompile
897 your windows APP if you're using ZOOM.
899 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
900 Commands "lang" and "charset" sets language and character set respectively.
901 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
902 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
904 Attributes from multiple CCL fields may be OR'ed rather than merged
905 using directive "@field or". Fields are still merged by default -
906 equivalent to "@field merge".
908 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
911 Fixed bug in zget for parameter ExtendedServicesResponse.
917 Added PQF feature: '@attr type=value' may be written as '@type=value'.
919 Client displays USR.1:SearchResult-1 (hits per term).
921 Additional Search Info for search in Generic Frontend Server.
923 Fixed CCL parsing of "field=s".
925 WIN32 installer - using the excellent NSIS software from nullsoft.
927 Fixed CCL parsing of "field = - <number>".
929 Added function yaz_marc_decode that decodes MARC for line mode
930 display or XML (similar to that used by JZKit).
932 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
933 Z39.50. But ISO/ILL was, however.
935 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
936 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
938 http://lcweb.loc.gov/z3950/agency/amend/am2.html
939 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
943 New YAZ client features: Command completion and new commands:
944 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
945 Code provided by Jacob Poulsen.
947 New call oid_trav, that visits all registered OIDs via callback.
949 Function ZOOM_record_get now returns const char pointer rather than
950 void pointer. It saves a lot of type casts.
952 For YAZ client, command "auth" now allows you to set authentication
953 in IdPass style. It is enabled when three tokens are given - order
954 is user, group and password.
956 Fix memory leaks in MARC record handling for ZOOM.
958 New option for YAZ client, -k <kilobytes> that sets
959 maximum record size. Similar to -k option for generic frontend
960 server and yaz-ztest.
962 More fixes for scan. Non-zero stepSize handled. OID's fixes.
964 Prefix query parser reports "fail" when bad attribute set is given.
966 Fix in MARC decoder. Proximity logging. Fix for attribute set
967 in scan handler for server. Patches by Shigeru Ishida.
969 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
972 Configure option --with-openssl=<dir> now works when a directory is
973 specified. Patch provided by Morten Bøgeskov.
975 New option for YAZ client, -u <auth>, that sets authentication.
977 ZOOM fix: error information was sometimes "missing", since error
978 was cleared/reset too when it shouldn't.
980 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
984 Scan for ZOOM API. New object ZOOM_scanset. New functions
985 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
986 ZOOM_scanset_destroy.
988 New ZOOM function, ZOOM_connection_last_event, that returns type
989 of last event (such as "receive data", "send data", "apdu received",
992 New ZOOM option, schema, that specifies schema for retrieval.
994 New CCL feature. Qualifiers can be aliases for one or more
995 other qualifiers (if more than one is given, OR is used).
997 ZOOM uses named result sets if target supports it.
999 Two new YAZ client commands: . (dot, which sources a script of YAZ
1000 client commands), and ! (to execute shell command.). Implemented
1003 Working on Debian packages.
1005 --- 1.8.3 2001/11/19
1007 YAZ client enables named result sets only if target supports it.
1009 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1011 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1012 with key="host" to get same result.
1014 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1015 Function Z3950_resultset_record(s) returns references to records
1016 "owned" by resultset. To become owner use Z3950_record_clone.
1018 Function z_ext_record handles Extended Services. Thanks to
1021 --- 1.8.2 2001/11/12
1023 CCL Parser fix: ignore token comma when dealing with and-lists.
1025 Documentation updates for COMSTACK.
1027 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1028 Changed prototype Z3950_records. For some functions, int parameters
1029 were changed to size_t.
1031 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1034 New MARC decode/display function, marc_display_exl, which properly rejects
1035 non-ISO2709 records. YAZ client uses it.
1037 --- 1.8.1 2001/10/29
1039 Fix bug: local attribute set wasn't set correctly in PQF strings.
1043 * Old Z39.50 codecs no longer supported.
1045 Added ZOOM C binding. See http://zoom.z3950.org/
1047 Renamed states for COMSTACKs to avoid confusion with events.
1049 Implemented cs_look and proper cs_rcvconnect.
1051 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1053 Configure detects POSIX threads on OpenBSD.
1055 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1056 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1058 When error is returned from present handler, non-surrogate diagnostic
1059 is returned in present response (and fetch handler is no longer called).
1061 * Minor adjustments to pquery parser (PQF). Token characters may be
1062 escaped by using backslash (C-style).
1064 PQF parser allows string attribute values to be specified. For @attr,
1065 non-numeric characters after the equal-sign are treated as strings
1066 (e.g. @attr 9=title).
1068 CCL trunction character may be defined (@truncation in file)
1070 * function zget_ExtendedServicesRequest sets waitAction to
1071 waitIfPossible (was wait).
1073 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1076 CCL operator names may be set in field definition files (CCL_bibset).
1077 See ccl/bib1 for an example.
1079 Fixes in ASN.1 compiler for C++ compatibility.
1081 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1082 and "op_or" to avoid conflict with C++.
1084 Fixed problem with GNU readline detection on Redhat 7.0.
1086 Added step-size for Scan backend handler.
1088 Fixed bug that made the frontend server crash when no attribute
1089 set was specified for scan.
1091 Front-end server automatically switches to original working directory
1092 when installed as an NT service. Previously -w had to be specified to
1095 Added extended attributes for retrieval module (data1), so that data1
1096 records carry d1_readXML/SGML attributes. d1_read also supports
1097 null-data rules ( <tag/>)
1099 On UNIX when POSIX threads are available, a separate library libyazthread
1100 is created. Programmers should link with that library and the yaz library
1101 when using threads. The reason for the split was that some applications
1102 on Linux, such as Apache, doesn't work well when using shared objects that
1105 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1106 (or any frontend server) in SSL mode by specifying ssl: followed by
1107 address. Only tested on UNIX.
1109 Added feature for CCL module. Virtual structure s=al or s=ol generates
1110 and-list and or-list respectively instead of phrase search.
1114 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1115 log_mask_str. This was done to avoid name conflicts with other libraries
1116 (such as other PHP extensions).
1118 Added raw OID member for preferred record syntax (request_format_raw)
1119 and returned record syntax (output_format_raw) for backend fetch method.
1121 Config file yaz-config now accepts options so that it returns specific
1122 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1124 Shared library support for UNIX using GNU libtool.
1126 * Modified backend interface. Request/Response struct's replaced by
1127 one read/write C struct. For example bend_fetchrequest and
1128 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1129 Every handler - even search has to be registered in bend_init
1130 handler. This means that the YAZ library no longer refers to
1131 external functions and it makes it possible to make the whole
1132 thing a single DLL/SO.
1134 Added Segment handler for backend server.
1136 Added Zmbol/Zebra administrative functions to YAZ client.
1138 Threaded frontend server on UNIX (when POSIX Threads are available).
1139 Starting the server with option -T enables multi-threading.
1143 Added configure option --enable-comp/disable-comp to control use
1144 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1145 located in sub directory asn.
1147 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1148 in ${exec_prefix}/bin along with the other programs yaz-client and
1151 GNU automake used to maintain makefiles.
1153 Added several OID's.
1155 Changed retrieval module so that we can load records with no abstract
1156 syntax defined. Tagpaths in these records are fully composed of string
1159 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1163 On UNIX, the generated makefile now supports a proper 'make install'.
1164 The prefix can be set via GNU configure to set the install location
1165 (default is /usr/local).
1167 * YAZ programs client and ztest were renamed to yaz-client and
1168 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1169 locations, such as /usr/bin,/usr/local/bin,etc.
1171 * YAZ Header files were moved from include to include/yaz. YAZ Header
1172 files are referred to as include <yaz/log.h> rather than <log.h>.
1173 The YAZ include path (-I ..) is therefore the same as before. Programmers
1174 should update their #include statements or use -Ipath/include/yaz
1175 instead. The main motivation for doing this change is that YAZ header files
1176 can be installed in "standard" locations /usr/include,/usr/local/include
1177 without introducing conflicts, since ALL YAZ header files are stored
1178 in subdirectory yaz (under /usr/include for example).
1180 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1181 rather than project/workspace files. We switched because project files
1182 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1185 Changed name of logging function, logf, to yaz_log, to prevent name
1186 clash with some math-log functions. The YAZ header log.h defines logf
1187 to yaz_log (#define) so there should be no incompatibilities by this
1190 Added bend_start/bend_stop handlers for server. These handler are
1191 called on start/stop of server. For windows they are called whenever
1192 a service is started/stopped.
1194 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1195 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1196 in util/yc.tcl. The auto-generated C code structures are, in a few
1197 cases, incompatible with the old decoders. There are differences in the
1198 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1199 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1200 The preprocessor variable ASN_COMPILED is defined when the compiled
1201 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1202 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1203 wish to use the old encoders/decoders you can specify --disable-yc
1206 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1207 version so that it supports both new - and old version of DB Update
1209 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1210 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1211 change. The name parameter can be set to 0 in which no name is specified
1212 for the construction. The macros odr_implicit and odr_explicit sets name
1213 parameter to zero for the construction involved. New macros
1214 odr_implicit_tag and odr_explicit_tag are similar to the others,
1215 except that a name parameter is added. For programmers' that don't use
1216 ODR they probably only need to change the call to z_APDU and z_External.
1218 Added access control facility by interfacing the TCP wrapper library.
1219 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1220 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1221 name of the daemon and enables the access control as specified in
1222 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1224 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1225 den Dool <H.M.vdnDool@kub.nl>.
1227 Added reference ID parameter to most functions in server API - refer
1228 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1230 Changed name of ccl library to libccl.a (was ccl.a).
1232 Fixed bug in decoder for Explain (Category TargetInfo).
1234 Added support for GNU readline in client. Thanks to Jacob Poulsen
1235 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1237 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1238 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1239 IMPLEMENTATION! This change was made to the development version before
1240 the ZIG decided to retract the amendment. If any users MUST be
1241 compatible with the original Update definition, PLEASE CONTACT US, and
1242 we will include a separate definition corresponding to the old Update
1243 ES. Note that because of the change to the ASN.1 of the
1244 TaskPackageRecordStructure we cannot define a single structure that
1245 will support both versions.
1247 * Added const modifier to buffer parameter for some ODR/BER encoding
1248 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1249 completeWAIS, odr_dumpBER.
1251 Fixed bug in client.c which caused a crash when a scanResponse didn't
1252 contain positionOfTerm.
1254 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1255 * will cause an error in a client if a non-YAZ target sends both a
1256 * list of Scan entries and non-surrogate diagnostics.
1258 Retrieval module enhancements. Tag sets may be typed in the reference
1259 to it. From the .abs-file the "tagset" directive takes a third optional
1260 integer type for the tag set referenced. From a .tag-file the "include"
1261 directive takes a third optional type as well. The old "type" directive
1262 in the tag set itself is still recognized but acts as the default type
1265 Backend interface change. Individual Scan terms returned from bend_scan
1266 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1267 in include/backend.h.
1269 Retrieval module enhancements. Multiple tag sets and attribute sets may
1270 be specified in abstract syntax specs. Revised the error/warning for
1271 logging messages reported by the retrieval module when reading the
1274 Object Identifier system (oid_..) changed. The API is backwards
1275 compatible but the oid-routines now allocates new OID's when needed.
1276 Raw OID's may be specified in oid_getvalbyname.
1278 YAZ now uses GNU configure to generate Makefile(s).
1280 * Minor changes in some of the member names of DeleteResultSetRequest and
1281 DeleteResultSetResponse. See include/proto.h.
1283 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1284 and added member 'languages' in TargetInfo (which was missing).
1286 Changed the way attribute sets are handled in the retrieval
1287 module. These are now cached, just like the abstract syntaxes
1290 Changed YAZ so that it links with compiled ASN.1.
1292 Added Explain-schema definitions and mapping routines. The following
1293 Explain categories have been implemented: AttributeDetails,
1294 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1296 Fixed minor bug in Windows version of Server Library.
1298 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1300 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1302 Added EXTERNAL: UNIverse Resource Report (non-standard).
1304 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1305 ENUMERATED and SET OF.
1307 * Added 'const' to some of the char pointer arguments for the
1308 functions, data1_read_node, data1_getelementbytagname,
1309 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1312 Fixed bug in data1_insert_taggeddata - the last_child member of
1313 parent wasn't initialised.
1315 * Changed data1_read_record and data1_read_node so that the supplied
1316 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1317 doesn't refer to any parts of the "SGML"-buffer.
1319 Fixed bug in server library (Windows version of statserv_remove).
1321 * Changed code so that it compiles as C++. The type definition
1322 of Odr_fun which is a member of Odr_arm was changed. The result is,
1323 that an explicit typecast is needed for the fun pointer when
1324 using Odr_arm - as in:
1325 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1327 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1329 Implemented the new structured date and time definition as approved
1330 by the ZIG. Added schemaId element to the specificTag in Espec-1
1331 (also approved at the last ZIG). Thanks to RVDM.
1333 Added some Object identifiers (RVDM).
1335 Changed the Update Extended Service (RVDM).
1337 Added command "refid" to client which specifies referenceId for
1338 the following requests.
1340 Implemented extended service handling for server. See ztest.c
1341 for an example as well as backend.h. New handlers are registerd
1342 in the Init handler.
1344 * Changed interface for sort in server.
1346 Added new members to statserv_options_block. It allows a server
1347 to read options from another source than just the command line. Thanks
1348 to Charles Woodfield.
1350 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1351 renamed to zboolean. Some C++ compilers complained about the name.
1353 Minor changes to gils.abs. Added index 's' (sort) on title
1354 and date/time-last-modified.
1356 --- 1.4pl2 1998/1/30
1358 Fixed bug in server library regarding inetd mode (-i). This bug
1359 was introduced by release 1.4.
1361 --- 1.4pl1 1998/1/29
1363 Added sort facility in client and backend server interface.
1365 Fixed problem with dependencies in Makefile(s).
1367 Fixed bugs for encoders/decoders of extended services and
1370 Implemented sub-tree feature for schemas. Sub-trees are
1371 referenced in *.abs-files. See explain.abs for an example
1372 of the use of this feature.
1374 Modified bib1.att; local attributes for ANY didn't include
1375 ANY itself (only affects use of the retrieval module).
1377 Fixed bug in plain SGML reader in function data1_read_node:
1378 tags with prefix "var" was incorrectly interpreted as variants.
1380 Added feature "sub-schemas" to enable references to - and definitions
1381 of - group of elements.
1383 * Removed member parent from type data1_element (in data1.h).
1385 Implemented function odr_nullval() that returns the value of
1388 * Removed member num_children from data1_node (in data1.h).
1390 Made NT service interface part of the server library. The
1391 function statserv_main uses the NT service when required and
1392 calls the statserv_start / statserv_close routines.
1394 Routine zget_SearchRequest and zget_PresentRequest fills
1395 resultSetName/Id member with "default" instead of "Default".
1397 Fixed memory leak in server. Request queue member wasn't freed.
1399 Fixed nmem_exit so that memory is freed.
1403 Revised the CCL parser utility to be thread safe.
1405 Added function, oid_ent_to_oid, to replace the function
1406 oid_getoidbyent, which is not thread safe.
1408 * Added nmem_init and nmem_exit to initialize and release
1409 NMEM resources. Function nmem_init should be called once in the
1410 initial thread before NMEM/ODR is used. statserv.c and client.c
1411 have been changed accordingly. The change was necessary to make
1412 NMEM thread safe. The NMEM memory pool is shared amongst threads
1413 in a process. Unix-based applications will still work fine without
1416 Added NT Services interface for the the Z39.50 (statserv) Server.
1417 Refer to the ztest.c source on the usage.
1419 Windows 95/NT port using MSVC5.0. Project files are included in the
1422 * Defined new 'global' handle for the retrieval (data1) system. The
1423 new handled, data1_handle, describes the state of the data1 system.
1424 This handle is passed as first argument to virtually all
1425 data1 related routines. The functions data1_create and data1_destroy
1426 creates and destroys a data1 handle respectively.
1428 Added ODR encode stream member to all backend request structures
1429 init, search, scan etc. This stream should be used to allocate all
1430 memory used for the response when thread safe operation is needed.
1432 Changed the comstack utility, cs_addstr, to be thread safe. The
1433 returned hostname string returned by the function is now part the
1436 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1437 function. The cs_straddr takes a COMSTACK handle as argument, so this
1438 function must be used after cs_create and before bind/connect.
1439 This function is thread safe.
1441 Moved test server to 'ztest' directory - generic server code still
1442 in 'server' directory.
1444 Made prefix query (pquery.c) utility thread safe.
1446 Added new function modifier YAZ_EXPORT to 'export' public DLL
1447 functions when using windows (see include/yconfig.h).
1449 Added definitions to the OID database (util/oid.c) (RVDM).
1451 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1453 Added call to ccl_rpn_delete in client program.
1455 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1456 release of RPN structure.
1458 Added support for C++, headers uses extern "C" for public definitions.
1459 With input from RVDM.
1461 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1462 Thanks to Ronald van der Meer (RVDM).
1464 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1466 Added support for private extensions to the OID database
1467 (oid_setprivateoids()). Thanks to RVDM.
1469 Added optional, physical ANY (key replication)
1471 Fixed null-reference problem in GRS-1 output filter.
1473 Proximity operator added to Prefix Query Format (PQF).
1475 In test client command "base" accepts multiple databases.
1477 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1481 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1483 Smallish bug-fixes in the new encoders/decoders (explain).
1485 Bug fixed in DeleteRequest.
1487 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1489 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1491 Added SOIF syntax (using private OID for now) to retrieval module and client.
1493 Added Update extended service.
1495 Added SearchResult-1 additional info structure.
1497 Added optional CCL (ISO8777) interpreter as separate module. Available
1500 --- 1.2 1996/6/10 (1st anniversary release)
1502 Added Summary record syntax. Lightly tested.
1504 Added OPAC record syntax. Untested.
1506 Added ResourceReport service encoders/decoders. Untested.
1508 Fixed bug in z_Unit - wrong tagging on unitSystem.
1510 Fixed bug in the DiagRecs decoder.
1512 Added options for max PDU size and session timeout to frontend-server.
1514 Added documentation of query-language parsers and other supporting utilities.
1516 [frontend-server] Added Attribute set to the bend_scanrequest API.
1518 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1519 surrogate diagnostics were generated.
1521 [retrieval] Allow multiple local values for attribute.
1523 [retrieval] Allow multiple attributes per element in .abs files. index type.
1525 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1527 --- 1.1pl2 1996/4/10
1529 Minor changes, mostly specific to Zebra's requirements (retrieval)
1533 Repaired bug in frontend server when running multiple listening
1534 endpoints in dynamic mode.
1536 z_External() now won't break if a known, ASN.1 value comes encapsulated
1537 in an octet-string. The value will pass through unmodified in an Odr_oct.
1539 Added a bit of code to the demo client to decode & display
1540 ASN.1-structured records represented in the octet-aligned branch of
1541 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1543 Added z_ext_getentbyref() to the ASN module. Doc updated.
1545 * Completed the SCAN definition in the ASN module. This may break SCAN
1546 code based on older YAZ-versions at compile-time. The fix is easy -
1549 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1550 under the SCAN definition. Remember to initialize this, server-people.
1552 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1553 that this does not extend to ODR and ASN.
1555 Comstack allows insertion of established socket (primarily for
1556 inetd-operation of servers). Doc updated.
1558 Front-end server can now start from the inetd in TCP mode. Doc
1561 --- 1.0pl4 1996/1/24
1565 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1566 the rank and record number.
1568 Adjustments to the frontend server.
1570 Fixed diagnostic BER dumper. It ignored the file argument.
1574 Various changes to retrieval module.
1576 Changed the union discriminators of the protocol files from enums to
1577 ints paired with #defines.
1579 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1582 *Changed operator in the RPN structure to 'roperator', again to avoid a
1585 Fixed problems in Explain decoders/encoders.
1587 --- 1.0pl2 1995/12/6
1589 Memory bug in log module fixed.
1591 --- 1.0pl1 1995/12/5
1593 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1595 Bug in Explain DatabaseInfo module fixed.
1597 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1601 The shift to v1.0 signals that we now consider the *core* functionality
1602 of YAZ reasonably stable (the core being more or less equivalent to
1603 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1604 tested (Explain not at all - though that will happen soonish).
1606 Minor changes to code to support Windows port.
1608 Various minor changes after we're getting to use GRS-1 & co. more.
1610 Added Espec-1 format.
1612 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1613 of the protocol and it cannot be selected when encoding (maps into 'string'
1614 when decoding). Needed to talk to some servers.
1616 Demo client can request simple element set names.
1618 Added Diagnostic Format encoders/decoders.
1620 Added simple Close handling to frontend server (no hooks for resource
1621 reporting yet), and demonstration client.
1623 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1625 --- 1.0b3 1995/08/24
1627 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1628 handled incorrectly when records were requested in the searchResponse. This
1629 will only affect you if you use the frontend-server.
1631 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1632 Test-client will ask for and print GRS1. Ztest will return dummy records
1635 Added Explain encoders/decoders to the service-level API. Untested.
1637 Added Extended Services: Item Order encoders and decoders to the Service-
1638 level API. Untested. We could use a recent copy of the pertinent bits
1639 of the ILL protocol to add those bits.
1641 Added diagnostic format 1 encoders/decoders to the service-level API.
1644 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1645 odr_cons.c, which causes a more correct output.
1647 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1648 was always set to 0 when no records were requested in the searchRequest.
1650 * Added better external-handling. This shouldn't harm old code that
1651 *encodes* externals. It can break code that looks for a
1652 'single-ASN1-type' representation, since those types that are known
1653 are now decoded immediately. Look at the SUTRS sample code in
1654 seshigh.c and client.c. Documentation updated.
1656 Handling of structured records in bend_fetchresponse. Length -1 marks
1657 structured record, type is deduced from format field.
1659 --- 1.0b2 1995/06/27
1660 Fairly quick maintenance release to add SUTRS support.
1662 Fixed handling of SUTRS records in the demonstration client.
1664 * Added format field to the bend_fetchrequest and bend_fetchresponce
1665 structures of the backend API (frontend server). When the record is
1666 returned, the value of the format field is mapped to an OID. The
1667 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1668 of the record. The special value VAL_NONE in the bend_request means
1669 that no specific format was requested by the client. Documentation
1670 updated accordingly. Test server (ztest) will return a fixed dummy
1671 SUTRS record if your client requests SUTRS.
1673 Documentation updated accordingly.
1675 You can now set external libraries and RANLIB support in the top-level
1679 First public release.
