1 Possible compatibility problems with earlier versions marked with '*'.
5 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
6 MARC output rather than returning "new" buffer.
8 yaz-client warns about unknown init options.
10 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
14 Added support for SRW sort in Generic Frontend Server. Patch
15 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
16 sortKeys - or NULL if none is provided.
18 Fixed bug #307: It was impossible to specify indefinite/no timeout
19 for ZOOM_event. Special timeout value -1 now means indefinite timeout
22 Added support for multiple languages and charsets to be specified in
23 ZOOM. Each charset/language is separated by a blank. If negotiation is
24 in effect in init-response, Option
25 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
26 Code based on patch by Vasiliy Osadchuk.
28 Fixed bug #306: infinite recursion that occurred when calling
29 yaz_log_level_init as the first call (before other log level or
32 Fixed bug in scan handling in front end server: if preferred-Position-In-
33 Response was non-present, a NULL pointer referece was performed.
37 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
38 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
39 now defined for all those error codes. So instead of putting 109 in
40 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
41 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
43 Modified the yaz-marcdump utility to skip garbage bytes between MARC
46 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
48 Program yaz-client now exits and produces an error message if multiple
49 Z39.50 servers are specified on the command line (none or one allowed
52 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
57 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
59 Fixed bug #272: Preserve spacing for CCL terms.
63 Added support for virtual hosts and multiple backend servers for
64 the YAZ frontend server. The configution is XML based and
65 support specificition of CQL to RPN mappings and explain information.
66 See section "Virtual Hosts" in the YAZ manual.
68 Extended OPAC display utility. OPAC display utility renders
69 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
70 to supplement yaz_marc_decode_wrbuf.
72 Fixed a bug in MARC decoder that could caused it to crash for some
73 invalid MARC records. More diagnostics and warnings where added in
74 XML output (warnings, etc are stored in comments).
78 Fixes for UNIX domain sockets. Bug #261.
80 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
82 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
83 Added yaz_marc_subfield_str which defines subfield lead string which is
84 used in YAZ_MARC_LINE format. Default string is blank+$. Added
85 yaz_marc_endline_str which defines end of fields string used in
86 YAZ_MARC_LINE format. Default string is newline.
88 Experimental support for MarcXChange. This format can be produced
89 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
90 http://www.bs.dk/standards/MarcXchange.xsd
92 Added yaz-client commands scansize that sets maximum number of
93 entries to be returned by scan.
97 Added support for SRW scan in yaz-client and Generic Frontend Server.
99 * Added whereInList member to SRW Scan Term.
101 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
103 Fixed NMEM system to return aligned blocks on the smallest boundaries
104 that are suitably aligned for all possible types on the particular
105 architecture YAZ is being built for.
107 --- 2.0.30 2005/01/04
109 Fixed numerious warnings that was issued with newer versions of GCC.
111 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
112 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
115 Make YAZ Generic Frontend Server slightly faster.
117 Enhance (and reduce) logging for Generic Frontend Server.
119 Revert YAZ log system so that it flushes every write operation
120 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
122 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
123 instead of LOG_, due to name clash with syslog(3). LOG_ are still
124 present. New applications should define YAZ_USE_NEW_LOG=1 - this
125 will effectively disable old definitions.
127 --- 2.0.28 2004/11/09
129 Added yaz_log_time_format which specifies log format using
132 Added yaz_log_module_level which returns mask for a module. Value
133 is non-zero mask a if module is enabled; zero if disabled.
135 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
136 in include/yaz/cql.h.
138 Fixed bug #176: Dont throw diagnostics on empty SRU args.
140 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
142 Fixed bug #172: RPM builds does not enable SSL.
144 Doxyfile.in part of dist. Doxyfile generated by configure.
146 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
147 are given and the corresponding component does not exist.
149 Extend CCL documentation in YAZ reference. Describe r=r.
151 --- 2.0.26 2004/10/01
153 Fixed MARC->MARCXML conversion to properly deal with
154 fields, subfields, indicators having non-ASCII characters.
156 Fixed MARC->MARCXML conversion so that ASCII control characters
157 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
160 Added YAZ GFS support for conversion from Z39.50 surrogate
161 diagnostics to SRW surrogate diagnostics.
163 Bug fix: YAZ GFS did not return schema in explainResponse.
165 --- 2.0.25 2004/09/30
167 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
168 now converts recordSchema to elementSetName as well as schema URI.
170 Fixed bug in COMSTACK that prevented HTTP request packages from being
173 --- 2.0.24 2004/09/29
175 Added CCL facility r=r "range" which is similar to r=o "ordered" but
176 does not require white-space before and after the dash in a range, e.g.
177 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
180 Fixed a few AC_TRY_LINK configure tests that did not operate properly
181 due to new GCC removing "redundant" code.
183 Added yaz-client commands scanpos and scanstep that sets preferred
184 position and step-size for scan.
186 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
188 Added CCL utility ccl_qual_buf which parses one or more CCL
189 spec lines in a buffer.
191 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
192 of name and value - ignoring empty lines and comments.
194 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
196 Added odr_get_element_path which returns current element path for an
197 ODR handle. This utility is useful in error handling or user-defined
200 Added ODR_PRINT utility odr_set_stream which is is a more generic
201 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
202 to a write function and pointer to close function. The close function - if
203 non-NULL - will be called during odr_destroy.
205 Fixed bug in CCL parser where truncation char was not removed from
206 right side when truncation=both was in effect.
208 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
211 --- 2.0.23 2004/08/11
213 Fix buffer overrun in CQL parser when dealing with proximity (%).
215 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
216 to UTF-8/UCS conversion is now only based on codetables.xml.
218 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
220 --- 2.0.22 2004/08/06
222 Add support for more "commit changes" in ZOOM (uses Extended Services).
224 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
227 Yet another small fix for configure of SSL.
229 --- 2.0.21 2004/05/14
231 Fix SSL libs for configure when --with-openssl=DIR is given.
233 --- 2.0.20 2004/05/10
235 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
237 SSL comstack now uses yaz.pem certificate file on server side
238 by default. Certificate filename can be configured by calling
239 comstack function cs_set_ssl_certificate_file before cs_bind is used.
241 Fix bug regarding multiple calls to ZOOM_connection_connect.
243 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
245 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
246 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
248 ZOOM now allows inspection of X509 peer certificate for verification.
249 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
251 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
252 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
253 as "modular" but it simplifies things.
255 Added cs_get_peer_certificate to that returns peer X509 PEM.
257 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
258 NULL if SSL is unavailable.
260 Documentation about MARC decoding tools.
262 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
264 --- 2.0.19 2004/03/30
266 Rename CHANGELOG to NEWS to follow GNU style packing.
268 Fix bug with missing initialization of member in init_diagnostics.
269 This bug affects threaded version of GFS server.
271 --- 2.0.18 2004/03/20
273 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
276 Ensure zlib.dll is packed with Windows install.
278 --- 2.0.17 2004/03/17
280 Fix encoding of xsd:string to use text instead of CDATA.
282 Fix endless loop in CQL parser with unbalanced ".
284 Use a more compact way to store MARC-8 conversion tables.
286 --- 2.0.16 2004/03/16 Debian only
288 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
291 Update CQL parser to use new CQL 1.1 modifiers for booleans and
296 --- 2.0.15 2004/03/01
298 Another fix for decoding of XML packed records.
300 --- 2.0.14 2004/02/25
302 Fixes for Chunked encoding. White space not ignored after length spec.
304 Update NS and use default NS for SRW diagnostic elements.
306 --- 2.0.13 2004/02/23
308 Implement ZOOM_resultset_cache_reset which resets record cache.
310 Implement ZOOM_resultset_sort which sorts a result set.
312 Implement chunked HTTP transfer.
314 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
316 --- 2.0.12 2004/02/16
318 Added member 'schema' to bend_explain_rr structure so that backend
319 can specify explain record identifier. Defaults to Zeerex 2.0.
321 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
323 --- 2.0.11 2004/02/16
325 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
328 Added init command for yaz-client which sends "extra" init request.
330 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
331 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
333 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
335 Make ZOOM error code for "invalid query".
337 Fixed compilation for SSL which wasn't properly enabled for all platforms.
339 --- 2.0.10 2004/02/05
341 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
344 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
346 Added option -p <file> to make Generic Frontend Server to write PID file.
348 Added option -D to put Generic Frontend Server in background on its own.
350 Make ZOOM C recognize option "password". If unset, "pass" is used
351 (for backwards compatibility).
353 Fixed a bug in Generic Frontend Server that could make it crash if a
354 client sets characterSetNegotation bit, but didn't pass negotiation stuff
357 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
358 Must be issued before open, in order to be in effect.
360 --- 2.0.9-6 2004/01/12 Debian/Windows
362 Make the SRU server more picky WRT unknown params, etc.
364 Bug fix: ZOOM scan response didn't return displayTerm - when present.
366 New YAZ client command, options, that sets Z39.50 options.
368 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
369 options from a string of tokens (one token for each option bit).
371 Update SRW diagnostic code messages.
373 --- 2.0.9-5 2004/01/07 Debian/Windows
375 Handle user defined stylesheet for SRW/SRU.
377 --- 2.0.9-4 2004/01/06 Debian/Windows
379 Fix bug in decoding of Content-Length.
381 --- 2.0.9-3 2004/01/06 Debian/Windows
383 Fix a bug with decoding of XML packed records.
385 --- 2.0.9-2 2004/01/05 Debian only
387 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
389 Fix bug in SRW/SRU diagnostics decoding.
393 Fixed bug in Generic Frontend Server which could drop records exceeding
394 preferred message size. Reported and fixed by Irina Dijour.
396 Fixed calculation of package size for structured records in Generic
397 Frontend Server. Reported and fixed by Irina Dijour.
399 Fixed namespace for SRW/SRU diagnostics.
401 Fixed SEGV in yaz-client that occured for HTTP connection errors.
405 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
406 this version is incompatible with version 1.0 and older YAZ SRW/SRU
409 CQL changes to reflect recent changes to the specification:
410 * Documentation talks about context sets instead of index sets.
411 * Documentation talks about indexes instead of qualifiers.
412 * The CQL-to-PQF transformer's configuration file now uses
413 "index.set.name = <attributes>" instead of the old form
414 "qualifier.set.name = <attributes>". (Both forms are still
415 understood but the latter is deprecated.)
416 * CQL terms with no explicit index specified are now interpreted as
417 cql.serverChoice instead of srw.serverChoice (which of course
418 behaves exactly the same.)
422 MARC conversion can now generate ISO2709 output in another
423 character set. yaz-marcdump uses this facility if you invoke it
426 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
427 functions from there can be used from C++.
431 Frontend server now transfers memory from decoded packages to stream
434 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
435 references to show up.
437 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
438 the ZOOM Abstract API. The older names for the same options are still
439 also supported for the benefit of old applications.
441 ZOOM-C supports "implementationId" and "implementationVersion" options
442 to go along with "implementationName". These allow the user code to
443 specify identification strings to be sent to servers.
444 Add OID for the new ExtLite attribute set.
446 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
447 as requested/supplid by Ere Maijala <ere@atp.fi>
449 For generic frontend server, reverse the order of
450 "toolkit-supplied / application-supplied" strings sent as implementationId,
451 Name and Version. Also, remove the spaces around the slash. This brings
452 the GFS in line with the behaviour of ZOOM-C on the client side.
454 Add function ZOOM_scanset_display_term.
456 yaz-client shows scan displayTerm if present.
458 Utility yaz-iconv is now installed by default along with the man page
461 Extend configure check for OpenSSL to use pkg-config where available (such
464 Incorporate patch by Morten Bogeskov which allows a Unix file socket
465 server to specify uid/gid/mask for socket using the format
466 unix:[user=uid,][group=gid,][umask=mask,]file=path
467 If file= is omitted the existing format is assumed, e.g.
469 in which case the mask is 0666 (rw for everybody).
471 Major restructure of YAZ source. All source in libyaz is in src directory.
472 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
473 util (utility programs such as ASN.1 compiler, yaz-marcdump).
475 Added man page for utility yaz-marcdump (used to be called marcdump).
476 yaz-marcdump is installed by 'make install'.
478 Fixed a memory leak in Generic Frontend Server that occurred when decoding
479 of incoming package failed.
481 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
483 Change prototype of odr_perror: add const to message string.
485 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
487 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
488 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
489 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
490 DNS lookup. There should not be any compatibility problems with this
491 assuming that blocking=1 or 0 is used.
493 Fix bad reference in UNIX comstack in function cs_addrstr.
495 Fix for compilation on AIX.
497 The generic front-end server (server/seshigh.c) now supports returning
498 Init diagnostics to the client in User-information-field, in
499 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
504 Allow any CQL relation (not just all,any,exact,scr).
506 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
507 that features the same UI.
509 Implemented command update0 in YAZ client which is equivalent to
510 update but uses old of Ext Update ASN.1.
512 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
513 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
514 Previously no OID was used for this info.
516 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
517 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
518 returns 'malformed search term' otherwise.
520 SortResponse member resultCount now set to NULL in sort handler of
523 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
526 Add three new utility functions for translating OIDs between various
527 formats -- symbolic name such as "Usmarc", minus-1-terminated int
528 arrays and dotted strings such as "1.2.840.10003.9.5.1":
529 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
530 char *oid_to_dotstring(const int *oid, char *oidbuf);
531 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
533 Reverted modifications for ES Update definition for z_IU0Update
534 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
535 is back to YAZ 2.0.2.
537 String value attributes for CCL parser.
539 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
540 which their FirstSearch server returns in Init responses, sometimes
541 carrying useful diagnostic information when Init fails. This has the
542 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
543 "z39.50/oclcui.asn", where its definition is somewhat different from
544 what OCLC document on their web-site, as required to interoperate with
547 Support for anonymous authentication in yaz-client. Use the command
550 * Fix the OID of the Index Data-local "admin" Extended Service from
551 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
552 the 1000, which indicates a locally-defined OID, was a mistake.
556 Fix CCL directive @case handling so that it affects string match for
557 both CCL keywords and qualifiers.
559 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
560 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
561 Decoder has been updated with ASN.1 changes as listed in
562 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
563 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
564 z_IUUpdate, remains unchanged.
566 ZOOM_record_get may now return a record in a specific character set.
567 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
568 "from" is the character set of record as returned by target. "to" is
569 the character set to be returned. If omitted, "to" is UTF-8.
571 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
573 New ODR utility, odr_getelement, which returns name of element for
574 which encoding/decoding failed.
576 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
577 in cases where a required element was omitted.
579 Bug fix: some MARC8 sequences were not converted.
581 New ZOOM option "step" which specifies number of records to be
582 retrieved in one chunk. Used in conjunction with "start" and "count".
584 SRW support for yaz-client. Use scheme http: to use it, e.g.
587 yaz-client no longer does (un)intelligent character set conversions
588 by default. Can be enabled with charset and marc_charset commands.
590 xmalloc trace fix for 64-bit systems such as DEC alpha.
592 Solaris 2.6 compile fix.
594 New function, cql_strerror() translates SRW error codes, as returned
595 by cql_transform_error(), into human-readable English strings. Used
596 in yaz-client diagnostics when appropriate.
598 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
599 converts it into a type-1 query which is sent to the server. This
600 makes CQL available for use with all Z-servers, as opposed to the tiny
601 minority that can handle CQL queries themselves.
605 New Debian package layout similar to the Redhat Package layout.
607 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
608 and search result respectively.
612 Redhat package is now several packages: libyaz (runtime libraries),
613 libyaz-devel (development and documentation, and yaz (utility programs).
614 Package spec file by Morten Bøgeskov.
616 New member 'schema' in struct bend_fetch_rr which the name of requested
617 schema (SRW/SRU) for record (or NULL if none was given). The fetch
618 handler MAY set this to reflect the schema of the returned record.
620 New member 'display_term' in struct scan_entry. GFS now sets member entries
621 and allocates scan entries to be filled by user scan handler. In previous
622 version, entries member was allocated by the scan handler. That still works,
623 but the GFS will ignore member display_term - assuming it was NOT set by
624 the handler. The fact that the GFS now allocates the entries both allows
625 for new members and makes a scan handler easier to write.
627 Fix CQL lex buffer overflow.
629 SRW/SRU recordPacking. For SRW default recordPacking is string. For
630 SRU default recordPacking is string.
632 SRU protocol support for frontend server.
634 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
636 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
638 Added scan for the ZOOM shell (zoomsh).
642 * String Identifers for Schemas (Amendment 5).
643 http://lcweb.loc.gov/z3950/agency/amend/am5.html
644 Old definition for schema
645 Odr_oid *schema; /* OPT */
650 Z_InternationalString *uri;
651 #define Z_Schema_oid 1
652 #define Z_Schema_uri 2
655 * resultCount parameter to Sort Response (Amendment 1).
656 http://lcweb.loc.gov/z3950/agency/amend/am1.html
658 Support for SRW 1.0 over HTTP. This is an optional feature and
659 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
662 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
663 on the same port. SRW SearchRetrieveRequests are mapped
664 to bend_init,bend_search,bend_fetch,bend_close.
666 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
668 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
669 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
671 ZOOM connections are SRW based if schem http is used for hostname
672 in connect, e.g. z = ZOOM_connection_new("http://myserver");
673 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
675 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
676 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
677 distance=n, order=true/false, relation=le, prox unit=word. If
678 n is omitted, distance 1 is used.
680 Fixed problem with C compiler include path in wrong order.
682 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
683 on Solaris. Patch from Ko van der Sloot.
685 New MARC decode API. All new functions operate on a yaz_marc_t
686 handle. The most important new functions are: yaz_marc_create,
687 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
688 decode and destroy respectively. Decoder can produce formats
689 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
690 include/yaz/marcdisp.h.
692 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
693 to UTF-8, UCS-32, wchar_t or Latin-1.
695 * Prototypes for yaz_iconv_-functions moved to separate header
696 include/yaz/yaz-iconv.h.
698 Make a few private functions 'static' in unix.c. This prevents
699 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
701 For ZOOM connection, the options targetImplementation{Id,Name,Version}
702 are set when Init Response is received.
704 New function ZOOM_connection_error_x similar to ZOOM_connection_error
705 but returns diagnostic set as well.
707 New function yaz_strerror which is a portable wrapper for
708 strerror/strerror_r/GetLastMessage.
710 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
711 is returned for MARC. If type is "oai", then OAI MARC is returned.
713 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
718 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
720 Fix bad race conditions on SIGTERM and terminate gracefully in
723 Move retrieval (data1) module to Zebra since nobody seems to be
726 Add GRS-1 render for ZOOM using same format as yaz-client.
730 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
732 Fix broken ESpec handling in data1 module.
734 SGML reader parses comments and makes them part of the data1 tree.
736 Added several type casts so that YAZ compiles as C++ code.
738 ZOOM didn't handle PDU encoding failures properly.
740 Added more Bib-1 diagnostics (approved extensions).
742 GNU configure: better check for iconv.
744 More portable use of accept, getpeername. Check for socklen_t. Use
745 int/size_t if socklen_t is not defined.
749 PQF parser rejects bad queries - including those with extra
750 characters in them. PQF parser used to silently ignore that.
751 Cleaner API for PQF added, which allows you to get detailed
752 error information for bad queries (see yaz/pquery.h).
754 Fixed bug in ZOOM_record_get for type "database".
756 Implemented mini iconv library supporting conversions between
757 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
759 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
763 Fixed ZOOM C record cache so that preferredRecordSyntax and
764 elementSetName is used to check for already fetched records.
768 Added three members in bend_initrequest structure to facilitate
769 character set negotiation.
771 Fixed a bug in frontend server that could cause indefinite
772 loops under rare conditions.
774 Revised character set utilities (charneg.h) so that encoding
775 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
777 For PQF, directive @term <type> sets term type for Scan/Search.
778 Here <type> is general, string, numeric, null. The term type
779 is inherited - just like @attr.
781 New call odr_set_charset that sets character set conversion for
782 international-strings on a ODR stream. Prototype is:
783 int odr_set_charset(ODR o, const char *to, const char *from);
784 The InternationalString is still represented as C string in YAZ
785 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
786 won't). On the protocol level, you can use any encoding.
788 Support for UNIX sockets in ZOOM.
790 Solaris recv sometimes returns errno == ENOENT. It is treated as
791 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
793 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
794 both client and server. Code by Morten Bøgeskov.
798 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
799 that they can be used directly from Visual Basic. You must recompile
800 your windows APP if you're using ZOOM.
802 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
803 Commands "lang" and "charset" sets language and character set respectively.
804 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
805 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
807 Attributes from multiple CCL fields may be OR'ed rather than merged
808 using directive "@field or". Fields are still merged by default -
809 equivalent to "@field merge".
811 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
814 Fixed bug in zget for parameter ExtendedServicesResponse.
820 Added PQF feature: '@attr type=value' may be written as '@type=value'.
822 Client displays USR.1:SearchResult-1 (hits per term).
824 Additional Search Info for search in Generic Frontend Server.
826 Fixed CCL parsing of "field=s".
828 WIN32 installer - using the excellent NSIS software from nullsoft.
830 Fixed CCL parsing of "field = - <number>".
832 Added function yaz_marc_decode that decodes MARC for line mode
833 display or XML (similar to that used by JZKit).
835 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
836 Z39.50. But ISO/ILL was, however.
838 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
839 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
841 http://lcweb.loc.gov/z3950/agency/amend/am2.html
842 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
846 New YAZ client features: Command completion and new commands:
847 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
848 Code provided by Jacob Poulsen.
850 New call oid_trav, that visits all registered OIDs via callback.
852 Function ZOOM_record_get now returns const char pointer rather than
853 void pointer. It saves a lot of type casts.
855 For YAZ client, command "auth" now allows you to set authentication
856 in IdPass style. It is enabled when three tokens are given - order
857 is user, group and password.
859 Fix memory leaks in MARC record handling for ZOOM.
861 New option for YAZ client, -k <kilobytes> that sets
862 maximum record size. Similar to -k option for generic frontend
863 server and yaz-ztest.
865 More fixes for scan. Non-zero stepSize handled. OID's fixes.
867 Prefix query parser reports "fail" when bad attribute set is given.
869 Fix in MARC decoder. Proximity logging. Fix for attribute set
870 in scan handler for server. Patches by Shigeru Ishida.
872 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
875 Configure option --with-openssl=<dir> now works when a directory is
876 specified. Patch provided by Morten Bøgeskov.
878 New option for YAZ client, -u <auth>, that sets authentication.
880 ZOOM fix: error information was sometimes "missing", since error
881 was cleared/reset too when it shouldn't.
883 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
887 Scan for ZOOM API. New object ZOOM_scanset. New functions
888 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
889 ZOOM_scanset_destroy.
891 New ZOOM function, ZOOM_connection_last_event, that returns type
892 of last event (such as "receive data", "send data", "apdu received",
895 New ZOOM option, schema, that specifies schema for retrieval.
897 New CCL feature. Qualifiers can be aliases for one or more
898 other qualifiers (if more than one is given, OR is used).
900 ZOOM uses named result sets if target supports it.
902 Two new YAZ client commands: . (dot, which sources a script of YAZ
903 client commands), and ! (to execute shell command.). Implemented
906 Working on Debian packages.
910 YAZ client enables named result sets only if target supports it.
912 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
914 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
915 with key="host" to get same result.
917 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
918 Function Z3950_resultset_record(s) returns references to records
919 "owned" by resultset. To become owner use Z3950_record_clone.
921 Function z_ext_record handles Extended Services. Thanks to
926 CCL Parser fix: ignore token comma when dealing with and-lists.
928 Documentation updates for COMSTACK.
930 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
931 Changed prototype Z3950_records. For some functions, int parameters
932 were changed to size_t.
934 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
937 New MARC decode/display function, marc_display_exl, which properly rejects
938 non-ISO2709 records. YAZ client uses it.
942 Fix bug: local attribute set wasn't set correctly in PQF strings.
946 * Old Z39.50 codecs no longer supported.
948 Added ZOOM C binding. See http://zoom.z3950.org/
950 Renamed states for COMSTACKs to avoid confusion with events.
952 Implemented cs_look and proper cs_rcvconnect.
954 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
956 Configure detects POSIX threads on OpenBSD.
958 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
959 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
961 When error is returned from present handler, non-surrogate diagnostic
962 is returned in present response (and fetch handler is no longer called).
964 * Minor adjustments to pquery parser (PQF). Token characters may be
965 escaped by using backslash (C-style).
967 PQF parser allows string attribute values to be specified. For @attr,
968 non-numeric characters after the equal-sign are treated as strings
969 (e.g. @attr 9=title).
971 CCL trunction character may be defined (@truncation in file)
973 * function zget_ExtendedServicesRequest sets waitAction to
974 waitIfPossible (was wait).
976 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
979 CCL operator names may be set in field definition files (CCL_bibset).
980 See ccl/bib1 for an example.
982 Fixes in ASN.1 compiler for C++ compatibility.
984 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
985 and "op_or" to avoid conflict with C++.
987 Fixed problem with GNU readline detection on Redhat 7.0.
989 Added step-size for Scan backend handler.
991 Fixed bug that made the frontend server crash when no attribute
992 set was specified for scan.
994 Front-end server automatically switches to original working directory
995 when installed as an NT service. Previously -w had to be specified to
998 Added extended attributes for retrieval module (data1), so that data1
999 records carry d1_readXML/SGML attributes. d1_read also supports
1000 null-data rules ( <tag/>)
1002 On UNIX when POSIX threads are available, a separate library libyazthread
1003 is created. Programmers should link with that library and the yaz library
1004 when using threads. The reason for the split was that some applications
1005 on Linux, such as Apache, doesn't work well when using shared objects that
1008 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1009 (or any frontend server) in SSL mode by specifying ssl: followed by
1010 address. Only tested on UNIX.
1012 Added feature for CCL module. Virtual structure s=al or s=ol generates
1013 and-list and or-list respectively instead of phrase search.
1017 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1018 log_mask_str. This was done to avoid name conflicts with other libraries
1019 (such as other PHP extensions).
1021 Added raw OID member for preferred record syntax (request_format_raw)
1022 and returned record syntax (output_format_raw) for backend fetch method.
1024 Config file yaz-config now accepts options so that it returns specific
1025 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1027 Shared library support for UNIX using GNU libtool.
1029 * Modified backend interface. Request/Response struct's replaced by
1030 one read/write C struct. For example bend_fetchrequest and
1031 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1032 Every handler - even search has to be registered in bend_init
1033 handler. This means that the YAZ library no longer refers to
1034 external functions and it makes it possible to make the whole
1035 thing a single DLL/SO.
1037 Added Segment handler for backend server.
1039 Added Zmbol/Zebra administrative functions to YAZ client.
1041 Threaded frontend server on UNIX (when POSIX Threads are available).
1042 Starting the server with option -T enables multi-threading.
1046 Added configure option --enable-comp/disable-comp to control use
1047 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1048 located in sub directory asn.
1050 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1051 in ${exec_prefix}/bin along with the other programs yaz-client and
1054 GNU automake used to maintain makefiles.
1056 Added several OID's.
1058 Changed retrieval module so that we can load records with no abstract
1059 syntax defined. Tagpaths in these records are fully composed of string
1062 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1066 On UNIX, the generated makefile now supports a proper 'make install'.
1067 The prefix can be set via GNU configure to set the install location
1068 (default is /usr/local).
1070 * YAZ programs client and ztest were renamed to yaz-client and
1071 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1072 locations, such as /usr/bin,/usr/local/bin,etc.
1074 * YAZ Header files were moved from include to include/yaz. YAZ Header
1075 files are referred to as include <yaz/log.h> rather than <log.h>.
1076 The YAZ include path (-I ..) is therefore the same as before. Programmers
1077 should update their #include statements or use -Ipath/include/yaz
1078 instead. The main motivation for doing this change is that YAZ header files
1079 can be installed in "standard" locations /usr/include,/usr/local/include
1080 without introducing conflicts, since ALL YAZ header files are stored
1081 in subdirectory yaz (under /usr/include for example).
1083 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1084 rather than project/workspace files. We switched because project files
1085 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1088 Changed name of logging function, logf, to yaz_log, to prevent name
1089 clash with some math-log functions. The YAZ header log.h defines logf
1090 to yaz_log (#define) so there should be no incompatibilities by this
1093 Added bend_start/bend_stop handlers for server. These handler are
1094 called on start/stop of server. For windows they are called whenever
1095 a service is started/stopped.
1097 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1098 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1099 in util/yc.tcl. The auto-generated C code structures are, in a few
1100 cases, incompatible with the old decoders. There are differences in the
1101 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1102 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1103 The preprocessor variable ASN_COMPILED is defined when the compiled
1104 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1105 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1106 wish to use the old encoders/decoders you can specify --disable-yc
1109 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1110 version so that it supports both new - and old version of DB Update
1112 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1113 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1114 change. The name parameter can be set to 0 in which no name is specified
1115 for the construction. The macros odr_implicit and odr_explicit sets name
1116 parameter to zero for the construction involved. New macros
1117 odr_implicit_tag and odr_explicit_tag are similar to the others,
1118 except that a name parameter is added. For programmers' that don't use
1119 ODR they probably only need to change the call to z_APDU and z_External.
1121 Added access control facility by interfacing the TCP wrapper library.
1122 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1123 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1124 name of the daemon and enables the access control as specified in
1125 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1127 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1128 den Dool <H.M.vdnDool@kub.nl>.
1130 Added reference ID parameter to most functions in server API - refer
1131 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1133 Changed name of ccl library to libccl.a (was ccl.a).
1135 Fixed bug in decoder for Explain (Category TargetInfo).
1137 Added support for GNU readline in client. Thanks to Jacob Poulsen
1138 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1140 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1141 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1142 IMPLEMENTATION! This change was made to the development version before
1143 the ZIG decided to retract the amendment. If any users MUST be
1144 compatible with the original Update definition, PLEASE CONTACT US, and
1145 we will include a separate definition corresponding to the old Update
1146 ES. Note that because of the change to the ASN.1 of the
1147 TaskPackageRecordStructure we cannot define a single structure that
1148 will support both versions.
1150 * Added const modifier to buffer parameter for some ODR/BER encoding
1151 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1152 completeWAIS, odr_dumpBER.
1154 Fixed bug in client.c which caused a crash when a scanResponse didn't
1155 contain positionOfTerm.
1157 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1158 * will cause an error in a client if a non-YAZ target sends both a
1159 * list of Scan entries and non-surrogate diagnostics.
1161 Retrieval module enhancements. Tag sets may be typed in the reference
1162 to it. From the .abs-file the "tagset" directive takes a third optional
1163 integer type for the tag set referenced. From a .tag-file the "include"
1164 directive takes a third optional type as well. The old "type" directive
1165 in the tag set itself is still recognized but acts as the default type
1168 Backend interface change. Individual Scan terms returned from bend_scan
1169 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1170 in include/backend.h.
1172 Retrieval module enhancements. Multiple tag sets and attribute sets may
1173 be specified in abstract syntax specs. Revised the error/warning for
1174 logging messages reported by the retrieval module when reading the
1177 Object Identifier system (oid_..) changed. The API is backwards
1178 compatible but the oid-routines now allocates new OID's when needed.
1179 Raw OID's may be specified in oid_getvalbyname.
1181 YAZ now uses GNU configure to generate Makefile(s).
1183 * Minor changes in some of the member names of DeleteResultSetRequest and
1184 DeleteResultSetResponse. See include/proto.h.
1186 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1187 and added member 'languages' in TargetInfo (which was missing).
1189 Changed the way attribute sets are handled in the retrieval
1190 module. These are now cached, just like the abstract syntaxes
1193 Changed YAZ so that it links with compiled ASN.1.
1195 Added Explain-schema definitions and mapping routines. The following
1196 Explain categories have been implemented: AttributeDetails,
1197 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1199 Fixed minor bug in Windows version of Server Library.
1201 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1203 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1205 Added EXTERNAL: UNIverse Resource Report (non-standard).
1207 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1208 ENUMERATED and SET OF.
1210 * Added 'const' to some of the char pointer arguments for the
1211 functions, data1_read_node, data1_getelementbytagname,
1212 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1215 Fixed bug in data1_insert_taggeddata - the last_child member of
1216 parent wasn't initialised.
1218 * Changed data1_read_record and data1_read_node so that the supplied
1219 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1220 doesn't refer to any parts of the "SGML"-buffer.
1222 Fixed bug in server library (Windows version of statserv_remove).
1224 * Changed code so that it compiles as C++. The type definition
1225 of Odr_fun which is a member of Odr_arm was changed. The result is,
1226 that an explicit typecast is needed for the fun pointer when
1227 using Odr_arm - as in:
1228 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1230 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1232 Implemented the new structured date and time definition as approved
1233 by the ZIG. Added schemaId element to the specificTag in Espec-1
1234 (also approved at the last ZIG). Thanks to RVDM.
1236 Added some Object identifiers (RVDM).
1238 Changed the Update Extended Service (RVDM).
1240 Added command "refid" to client which specifies referenceId for
1241 the following requests.
1243 Implemented extended service handling for server. See ztest.c
1244 for an example as well as backend.h. New handlers are registerd
1245 in the Init handler.
1247 * Changed interface for sort in server.
1249 Added new members to statserv_options_block. It allows a server
1250 to read options from another source than just the command line. Thanks
1251 to Charles Woodfield.
1253 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1254 renamed to zboolean. Some C++ compilers complained about the name.
1256 Minor changes to gils.abs. Added index 's' (sort) on title
1257 and date/time-last-modified.
1259 --- 1.4pl2 1998/1/30
1261 Fixed bug in server library regarding inetd mode (-i). This bug
1262 was introduced by release 1.4.
1264 --- 1.4pl1 1998/1/29
1266 Added sort facility in client and backend server interface.
1268 Fixed problem with dependencies in Makefile(s).
1270 Fixed bugs for encoders/decoders of extended services and
1273 Implemented sub-tree feature for schemas. Sub-trees are
1274 referenced in *.abs-files. See explain.abs for an example
1275 of the use of this feature.
1277 Modified bib1.att; local attributes for ANY didn't include
1278 ANY itself (only affects use of the retrieval module).
1280 Fixed bug in plain SGML reader in function data1_read_node:
1281 tags with prefix "var" was incorrectly interpreted as variants.
1283 Added feature "sub-schemas" to enable references to - and definitions
1284 of - group of elements.
1286 * Removed member parent from type data1_element (in data1.h).
1288 Implemented function odr_nullval() that returns the value of
1291 * Removed member num_children from data1_node (in data1.h).
1293 Made NT service interface part of the server library. The
1294 function statserv_main uses the NT service when required and
1295 calls the statserv_start / statserv_close routines.
1297 Routine zget_SearchRequest and zget_PresentRequest fills
1298 resultSetName/Id member with "default" instead of "Default".
1300 Fixed memory leak in server. Request queue member wasn't freed.
1302 Fixed nmem_exit so that memory is freed.
1306 Revised the CCL parser utility to be thread safe.
1308 Added function, oid_ent_to_oid, to replace the function
1309 oid_getoidbyent, which is not thread safe.
1311 * Added nmem_init and nmem_exit to initialize and release
1312 NMEM resources. Function nmem_init should be called once in the
1313 initial thread before NMEM/ODR is used. statserv.c and client.c
1314 have been changed accordingly. The change was necessary to make
1315 NMEM thread safe. The NMEM memory pool is shared amongst threads
1316 in a process. Unix-based applications will still work fine without
1319 Added NT Services interface for the the Z39.50 (statserv) Server.
1320 Refer to the ztest.c source on the usage.
1322 Windows 95/NT port using MSVC5.0. Project files are included in the
1325 * Defined new 'global' handle for the retrieval (data1) system. The
1326 new handled, data1_handle, describes the state of the data1 system.
1327 This handle is passed as first argument to virtually all
1328 data1 related routines. The functions data1_create and data1_destroy
1329 creates and destroys a data1 handle respectively.
1331 Added ODR encode stream member to all backend request structures
1332 init, search, scan etc. This stream should be used to allocate all
1333 memory used for the response when thread safe operation is needed.
1335 Changed the comstack utility, cs_addstr, to be thread safe. The
1336 returned hostname string returned by the function is now part the
1339 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1340 function. The cs_straddr takes a COMSTACK handle as argument, so this
1341 function must be used after cs_create and before bind/connect.
1342 This function is thread safe.
1344 Moved test server to 'ztest' directory - generic server code still
1345 in 'server' directory.
1347 Made prefix query (pquery.c) utility thread safe.
1349 Added new function modifier YAZ_EXPORT to 'export' public DLL
1350 functions when using windows (see include/yconfig.h).
1352 Added definitions to the OID database (util/oid.c) (RVDM).
1354 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1356 Added call to ccl_rpn_delete in client program.
1358 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1359 release of RPN structure.
1361 Added support for C++, headers uses extern "C" for public definitions.
1362 With input from RVDM.
1364 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1365 Thanks to Ronald van der Meer (RVDM).
1367 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1369 Added support for private extensions to the OID database
1370 (oid_setprivateoids()). Thanks to RVDM.
1372 Added optional, physical ANY (key replication)
1374 Fixed null-reference problem in GRS-1 output filter.
1376 Proximity operator added to Prefix Query Format (PQF).
1378 In test client command "base" accepts multiple databases.
1380 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1384 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1386 Smallish bug-fixes in the new encoders/decoders (explain).
1388 Bug fixed in DeleteRequest.
1390 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1392 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1394 Added SOIF syntax (using private OID for now) to retrieval module and client.
1396 Added Update extended service.
1398 Added SearchResult-1 additional info structure.
1400 Added optional CCL (ISO8777) interpreter as separate module. Available
1403 --- 1.2 1996/6/10 (1st anniversary release)
1405 Added Summary record syntax. Lightly tested.
1407 Added OPAC record syntax. Untested.
1409 Added ResourceReport service encoders/decoders. Untested.
1411 Fixed bug in z_Unit - wrong tagging on unitSystem.
1413 Fixed bug in the DiagRecs decoder.
1415 Added options for max PDU size and session timeout to frontend-server.
1417 Added documentation of query-language parsers and other supporting utilities.
1419 [frontend-server] Added Attribute set to the bend_scanrequest API.
1421 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1422 surrogate diagnostics were generated.
1424 [retrieval] Allow multiple local values for attribute.
1426 [retrieval] Allow multiple attributes per element in .abs files. index type.
1428 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1430 --- 1.1pl2 1996/4/10
1432 Minor changes, mostly specific to Zebra's requirements (retrieval)
1436 Repaired bug in frontend server when running multiple listening
1437 endpoints in dynamic mode.
1439 z_External() now won't break if a known, ASN.1 value comes encapsulated
1440 in an octet-string. The value will pass through unmodified in an Odr_oct.
1442 Added a bit of code to the demo client to decode & display
1443 ASN.1-structured records represented in the octet-aligned branch of
1444 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1446 Added z_ext_getentbyref() to the ASN module. Doc updated.
1448 * Completed the SCAN definition in the ASN module. This may break SCAN
1449 code based on older YAZ-versions at compile-time. The fix is easy -
1452 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1453 under the SCAN definition. Remember to initialize this, server-people.
1455 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1456 that this does not extend to ODR and ASN.
1458 Comstack allows insertion of established socket (primarily for
1459 inetd-operation of servers). Doc updated.
1461 Front-end server can now start from the inetd in TCP mode. Doc
1464 --- 1.0pl4 1996/1/24
1468 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1469 the rank and record number.
1471 Adjustments to the frontend server.
1473 Fixed diagnostic BER dumper. It ignored the file argument.
1477 Various changes to retrieval module.
1479 Changed the union discriminators of the protocol files from enums to
1480 ints paired with #defines.
1482 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1485 *Changed operator in the RPN structure to 'roperator', again to avoid a
1488 Fixed problems in Explain decoders/encoders.
1490 --- 1.0pl2 1995/12/6
1492 Memory bug in log module fixed.
1494 --- 1.0pl1 1995/12/5
1496 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1498 Bug in Explain DatabaseInfo module fixed.
1500 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1504 The shift to v1.0 signals that we now consider the *core* functionality
1505 of YAZ reasonably stable (the core being more or less equivalent to
1506 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1507 tested (Explain not at all - though that will happen soonish).
1509 Minor changes to code to support Windows port.
1511 Various minor changes after we're getting to use GRS-1 & co. more.
1513 Added Espec-1 format.
1515 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1516 of the protocol and it cannot be selected when encoding (maps into 'string'
1517 when decoding). Needed to talk to some servers.
1519 Demo client can request simple element set names.
1521 Added Diagnostic Format encoders/decoders.
1523 Added simple Close handling to frontend server (no hooks for resource
1524 reporting yet), and demonstration client.
1526 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1528 --- 1.0b3 1995/08/24
1530 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1531 handled incorrectly when records were requested in the searchResponse. This
1532 will only affect you if you use the frontend-server.
1534 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1535 Test-client will ask for and print GRS1. Ztest will return dummy records
1538 Added Explain encoders/decoders to the service-level API. Untested.
1540 Added Extended Services: Item Order encoders and decoders to the Service-
1541 level API. Untested. We could use a recent copy of the pertinent bits
1542 of the ILL protocol to add those bits.
1544 Added diagnostic format 1 encoders/decoders to the service-level API.
1547 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1548 odr_cons.c, which causes a more correct output.
1550 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1551 was always set to 0 when no records were requested in the searchRequest.
1553 * Added better external-handling. This shouldn't harm old code that
1554 *encodes* externals. It can break code that looks for a
1555 'single-ASN1-type' representation, since those types that are known
1556 are now decoded immediately. Look at the SUTRS sample code in
1557 seshigh.c and client.c. Documentation updated.
1559 Handling of structured records in bend_fetchresponse. Length -1 marks
1560 structured record, type is deduced from format field.
1562 --- 1.0b2 1995/06/27
1563 Fairly quick maintenance release to add SUTRS support.
1565 Fixed handling of SUTRS records in the demonstration client.
1567 * Added format field to the bend_fetchrequest and bend_fetchresponce
1568 structures of the backend API (frontend server). When the record is
1569 returned, the value of the format field is mapped to an OID. The
1570 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1571 of the record. The special value VAL_NONE in the bend_request means
1572 that no specific format was requested by the client. Documentation
1573 updated accordingly. Test server (ztest) will return a fixed dummy
1574 SUTRS record if your client requests SUTRS.
1576 Documentation updated accordingly.
1578 You can now set external libraries and RANLIB support in the top-level
1582 First public release.
