1 Possible compatibility problems with earlier versions marked with '*'.
5 Added support for SRW sort in Generic Frontend Server. Patch
6 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
7 sortKeys - or NULL if none is provided.
9 Fixed bug #307: It was impossible to specify indefinite/no timeout
10 for ZOOM_event. Special timeout value -1 now means indefinite timeout
13 Added support for multiple languages and charsets to be specified in
14 ZOOM. Each charset/language is separated by a blank. If negotiation is
15 in effect in init-response, Option
16 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
17 Code based on patch by Vasiliy Osadchuk.
19 Fixed bug #306: infinite recursion that occurred when calling
20 yaz_log_level_init as the first call (before other log level or
23 Fixed bug in scan handling in front end server: if preferred-Position-In-
24 Response was non-present, a NULL pointer referece was performed.
28 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
29 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
30 now defined for all those error codes. So instead of putting 109 in
31 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
32 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
34 Modified the yaz-marcdump utility to skip garbage bytes between MARC
37 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
39 Program yaz-client now exits and produces an error message if multiple
40 Z39.50 servers are specified on the command line (none or one allowed
43 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
48 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
50 Fixed bug #272: Preserve spacing for CCL terms.
54 Added support for virtual hosts and multiple backend servers for
55 the YAZ frontend server. The configution is XML based and
56 support specificition of CQL to RPN mappings and explain information.
57 See section "Virtual Hosts" in the YAZ manual.
59 Extended OPAC display utility. OPAC display utility renders
60 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
61 to supplement yaz_marc_decode_wrbuf.
63 Fixed a bug in MARC decoder that could caused it to crash for some
64 invalid MARC records. More diagnostics and warnings where added in
65 XML output (warnings, etc are stored in comments).
69 Fixes for UNIX domain sockets. Bug #261.
71 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
73 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
74 Added yaz_marc_subfield_str which defines subfield lead string which is
75 used in YAZ_MARC_LINE format. Default string is blank+$. Added
76 yaz_marc_endline_str which defines end of fields string used in
77 YAZ_MARC_LINE format. Default string is newline.
79 Experimental support for MarcXChange. This format can be produced
80 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
81 http://www.bs.dk/standards/MarcXchange.xsd
83 Added yaz-client commands scansize that sets maximum number of
84 entries to be returned by scan.
88 Added support for SRW scan in yaz-client and Generic Frontend Server.
90 * Added whereInList member to SRW Scan Term.
92 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
94 Fixed NMEM system to return aligned blocks on the smallest boundaries
95 that are suitably aligned for all possible types on the particular
96 architecture YAZ is being built for.
100 Fixed numerious warnings that was issued with newer versions of GCC.
102 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
103 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
106 Make YAZ Generic Frontend Server slightly faster.
108 Enhance (and reduce) logging for Generic Frontend Server.
110 Revert YAZ log system so that it flushes every write operation
111 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
113 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
114 instead of LOG_, due to name clash with syslog(3). LOG_ are still
115 present. New applications should define YAZ_USE_NEW_LOG=1 - this
116 will effectively disable old definitions.
118 --- 2.0.28 2004/11/09
120 Added yaz_log_time_format which specifies log format using
123 Added yaz_log_module_level which returns mask for a module. Value
124 is non-zero mask a if module is enabled; zero if disabled.
126 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
127 in include/yaz/cql.h.
129 Fixed bug #176: Dont throw diagnostics on empty SRU args.
131 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
133 Fixed bug #172: RPM builds does not enable SSL.
135 Doxyfile.in part of dist. Doxyfile generated by configure.
137 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
138 are given and the corresponding component does not exist.
140 Extend CCL documentation in YAZ reference. Describe r=r.
142 --- 2.0.26 2004/10/01
144 Fixed MARC->MARCXML conversion to properly deal with
145 fields, subfields, indicators having non-ASCII characters.
147 Fixed MARC->MARCXML conversion so that ASCII control characters
148 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
151 Added YAZ GFS support for conversion from Z39.50 surrogate
152 diagnostics to SRW surrogate diagnostics.
154 Bug fix: YAZ GFS did not return schema in explainResponse.
156 --- 2.0.25 2004/09/30
158 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
159 now converts recordSchema to elementSetName as well as schema URI.
161 Fixed bug in COMSTACK that prevented HTTP request packages from being
164 --- 2.0.24 2004/09/29
166 Added CCL facility r=r "range" which is similar to r=o "ordered" but
167 does not require white-space before and after the dash in a range, e.g.
168 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
171 Fixed a few AC_TRY_LINK configure tests that did not operate properly
172 due to new GCC removing "redundant" code.
174 Added yaz-client commands scanpos and scanstep that sets preferred
175 position and step-size for scan.
177 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
179 Added CCL utility ccl_qual_buf which parses one or more CCL
180 spec lines in a buffer.
182 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
183 of name and value - ignoring empty lines and comments.
185 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
187 Added odr_get_element_path which returns current element path for an
188 ODR handle. This utility is useful in error handling or user-defined
191 Added ODR_PRINT utility odr_set_stream which is is a more generic
192 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
193 to a write function and pointer to close function. The close function - if
194 non-NULL - will be called during odr_destroy.
196 Fixed bug in CCL parser where truncation char was not removed from
197 right side when truncation=both was in effect.
199 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
202 --- 2.0.23 2004/08/11
204 Fix buffer overrun in CQL parser when dealing with proximity (%).
206 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
207 to UTF-8/UCS conversion is now only based on codetables.xml.
209 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
211 --- 2.0.22 2004/08/06
213 Add support for more "commit changes" in ZOOM (uses Extended Services).
215 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
218 Yet another small fix for configure of SSL.
220 --- 2.0.21 2004/05/14
222 Fix SSL libs for configure when --with-openssl=DIR is given.
224 --- 2.0.20 2004/05/10
226 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
228 SSL comstack now uses yaz.pem certificate file on server side
229 by default. Certificate filename can be configured by calling
230 comstack function cs_set_ssl_certificate_file before cs_bind is used.
232 Fix bug regarding multiple calls to ZOOM_connection_connect.
234 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
236 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
237 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
239 ZOOM now allows inspection of X509 peer certificate for verification.
240 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
242 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
243 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
244 as "modular" but it simplifies things.
246 Added cs_get_peer_certificate to that returns peer X509 PEM.
248 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
249 NULL if SSL is unavailable.
251 Documentation about MARC decoding tools.
253 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
255 --- 2.0.19 2004/03/30
257 Rename CHANGELOG to NEWS to follow GNU style packing.
259 Fix bug with missing initialization of member in init_diagnostics.
260 This bug affects threaded version of GFS server.
262 --- 2.0.18 2004/03/20
264 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
267 Ensure zlib.dll is packed with Windows install.
269 --- 2.0.17 2004/03/17
271 Fix encoding of xsd:string to use text instead of CDATA.
273 Fix endless loop in CQL parser with unbalanced ".
275 Use a more compact way to store MARC-8 conversion tables.
277 --- 2.0.16 2004/03/16 Debian only
279 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
282 Update CQL parser to use new CQL 1.1 modifiers for booleans and
287 --- 2.0.15 2004/03/01
289 Another fix for decoding of XML packed records.
291 --- 2.0.14 2004/02/25
293 Fixes for Chunked encoding. White space not ignored after length spec.
295 Update NS and use default NS for SRW diagnostic elements.
297 --- 2.0.13 2004/02/23
299 Implement ZOOM_resultset_cache_reset which resets record cache.
301 Implement ZOOM_resultset_sort which sorts a result set.
303 Implement chunked HTTP transfer.
305 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
307 --- 2.0.12 2004/02/16
309 Added member 'schema' to bend_explain_rr structure so that backend
310 can specify explain record identifier. Defaults to Zeerex 2.0.
312 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
314 --- 2.0.11 2004/02/16
316 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
319 Added init command for yaz-client which sends "extra" init request.
321 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
322 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
324 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
326 Make ZOOM error code for "invalid query".
328 Fixed compilation for SSL which wasn't properly enabled for all platforms.
330 --- 2.0.10 2004/02/05
332 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
335 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
337 Added option -p <file> to make Generic Frontend Server to write PID file.
339 Added option -D to put Generic Frontend Server in background on its own.
341 Make ZOOM C recognize option "password". If unset, "pass" is used
342 (for backwards compatibility).
344 Fixed a bug in Generic Frontend Server that could make it crash if a
345 client sets characterSetNegotation bit, but didn't pass negotiation stuff
348 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
349 Must be issued before open, in order to be in effect.
351 --- 2.0.9-6 2004/01/12 Debian/Windows
353 Make the SRU server more picky WRT unknown params, etc.
355 Bug fix: ZOOM scan response didn't return displayTerm - when present.
357 New YAZ client command, options, that sets Z39.50 options.
359 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
360 options from a string of tokens (one token for each option bit).
362 Update SRW diagnostic code messages.
364 --- 2.0.9-5 2004/01/07 Debian/Windows
366 Handle user defined stylesheet for SRW/SRU.
368 --- 2.0.9-4 2004/01/06 Debian/Windows
370 Fix bug in decoding of Content-Length.
372 --- 2.0.9-3 2004/01/06 Debian/Windows
374 Fix a bug with decoding of XML packed records.
376 --- 2.0.9-2 2004/01/05 Debian only
378 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
380 Fix bug in SRW/SRU diagnostics decoding.
384 Fixed bug in Generic Frontend Server which could drop records exceeding
385 preferred message size. Reported and fixed by Irina Dijour.
387 Fixed calculation of package size for structured records in Generic
388 Frontend Server. Reported and fixed by Irina Dijour.
390 Fixed namespace for SRW/SRU diagnostics.
392 Fixed SEGV in yaz-client that occured for HTTP connection errors.
396 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
397 this version is incompatible with version 1.0 and older YAZ SRW/SRU
400 CQL changes to reflect recent changes to the specification:
401 * Documentation talks about context sets instead of index sets.
402 * Documentation talks about indexes instead of qualifiers.
403 * The CQL-to-PQF transformer's configuration file now uses
404 "index.set.name = <attributes>" instead of the old form
405 "qualifier.set.name = <attributes>". (Both forms are still
406 understood but the latter is deprecated.)
407 * CQL terms with no explicit index specified are now interpreted as
408 cql.serverChoice instead of srw.serverChoice (which of course
409 behaves exactly the same.)
413 MARC conversion can now generate ISO2709 output in another
414 character set. yaz-marcdump uses this facility if you invoke it
417 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
418 functions from there can be used from C++.
422 Frontend server now transfers memory from decoded packages to stream
425 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
426 references to show up.
428 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
429 the ZOOM Abstract API. The older names for the same options are still
430 also supported for the benefit of old applications.
432 ZOOM-C supports "implementationId" and "implementationVersion" options
433 to go along with "implementationName". These allow the user code to
434 specify identification strings to be sent to servers.
435 Add OID for the new ExtLite attribute set.
437 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
438 as requested/supplid by Ere Maijala <ere@atp.fi>
440 For generic frontend server, reverse the order of
441 "toolkit-supplied / application-supplied" strings sent as implementationId,
442 Name and Version. Also, remove the spaces around the slash. This brings
443 the GFS in line with the behaviour of ZOOM-C on the client side.
445 Add function ZOOM_scanset_display_term.
447 yaz-client shows scan displayTerm if present.
449 Utility yaz-iconv is now installed by default along with the man page
452 Extend configure check for OpenSSL to use pkg-config where available (such
455 Incorporate patch by Morten Bogeskov which allows a Unix file socket
456 server to specify uid/gid/mask for socket using the format
457 unix:[user=uid,][group=gid,][umask=mask,]file=path
458 If file= is omitted the existing format is assumed, e.g.
460 in which case the mask is 0666 (rw for everybody).
462 Major restructure of YAZ source. All source in libyaz is in src directory.
463 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
464 util (utility programs such as ASN.1 compiler, yaz-marcdump).
466 Added man page for utility yaz-marcdump (used to be called marcdump).
467 yaz-marcdump is installed by 'make install'.
469 Fixed a memory leak in Generic Frontend Server that occurred when decoding
470 of incoming package failed.
472 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
474 Change prototype of odr_perror: add const to message string.
476 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
478 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
479 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
480 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
481 DNS lookup. There should not be any compatibility problems with this
482 assuming that blocking=1 or 0 is used.
484 Fix bad reference in UNIX comstack in function cs_addrstr.
486 Fix for compilation on AIX.
488 The generic front-end server (server/seshigh.c) now supports returning
489 Init diagnostics to the client in User-information-field, in
490 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
495 Allow any CQL relation (not just all,any,exact,scr).
497 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
498 that features the same UI.
500 Implemented command update0 in YAZ client which is equivalent to
501 update but uses old of Ext Update ASN.1.
503 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
504 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
505 Previously no OID was used for this info.
507 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
508 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
509 returns 'malformed search term' otherwise.
511 SortResponse member resultCount now set to NULL in sort handler of
514 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
517 Add three new utility functions for translating OIDs between various
518 formats -- symbolic name such as "Usmarc", minus-1-terminated int
519 arrays and dotted strings such as "1.2.840.10003.9.5.1":
520 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
521 char *oid_to_dotstring(const int *oid, char *oidbuf);
522 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
524 Reverted modifications for ES Update definition for z_IU0Update
525 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
526 is back to YAZ 2.0.2.
528 String value attributes for CCL parser.
530 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
531 which their FirstSearch server returns in Init responses, sometimes
532 carrying useful diagnostic information when Init fails. This has the
533 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
534 "z39.50/oclcui.asn", where its definition is somewhat different from
535 what OCLC document on their web-site, as required to interoperate with
538 Support for anonymous authentication in yaz-client. Use the command
541 * Fix the OID of the Index Data-local "admin" Extended Service from
542 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
543 the 1000, which indicates a locally-defined OID, was a mistake.
547 Fix CCL directive @case handling so that it affects string match for
548 both CCL keywords and qualifiers.
550 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
551 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
552 Decoder has been updated with ASN.1 changes as listed in
553 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
554 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
555 z_IUUpdate, remains unchanged.
557 ZOOM_record_get may now return a record in a specific character set.
558 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
559 "from" is the character set of record as returned by target. "to" is
560 the character set to be returned. If omitted, "to" is UTF-8.
562 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
564 New ODR utility, odr_getelement, which returns name of element for
565 which encoding/decoding failed.
567 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
568 in cases where a required element was omitted.
570 Bug fix: some MARC8 sequences were not converted.
572 New ZOOM option "step" which specifies number of records to be
573 retrieved in one chunk. Used in conjunction with "start" and "count".
575 SRW support for yaz-client. Use scheme http: to use it, e.g.
578 yaz-client no longer does (un)intelligent character set conversions
579 by default. Can be enabled with charset and marc_charset commands.
581 xmalloc trace fix for 64-bit systems such as DEC alpha.
583 Solaris 2.6 compile fix.
585 New function, cql_strerror() translates SRW error codes, as returned
586 by cql_transform_error(), into human-readable English strings. Used
587 in yaz-client diagnostics when appropriate.
589 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
590 converts it into a type-1 query which is sent to the server. This
591 makes CQL available for use with all Z-servers, as opposed to the tiny
592 minority that can handle CQL queries themselves.
596 New Debian package layout similar to the Redhat Package layout.
598 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
599 and search result respectively.
603 Redhat package is now several packages: libyaz (runtime libraries),
604 libyaz-devel (development and documentation, and yaz (utility programs).
605 Package spec file by Morten Bøgeskov.
607 New member 'schema' in struct bend_fetch_rr which the name of requested
608 schema (SRW/SRU) for record (or NULL if none was given). The fetch
609 handler MAY set this to reflect the schema of the returned record.
611 New member 'display_term' in struct scan_entry. GFS now sets member entries
612 and allocates scan entries to be filled by user scan handler. In previous
613 version, entries member was allocated by the scan handler. That still works,
614 but the GFS will ignore member display_term - assuming it was NOT set by
615 the handler. The fact that the GFS now allocates the entries both allows
616 for new members and makes a scan handler easier to write.
618 Fix CQL lex buffer overflow.
620 SRW/SRU recordPacking. For SRW default recordPacking is string. For
621 SRU default recordPacking is string.
623 SRU protocol support for frontend server.
625 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
627 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
629 Added scan for the ZOOM shell (zoomsh).
633 * String Identifers for Schemas (Amendment 5).
634 http://lcweb.loc.gov/z3950/agency/amend/am5.html
635 Old definition for schema
636 Odr_oid *schema; /* OPT */
641 Z_InternationalString *uri;
642 #define Z_Schema_oid 1
643 #define Z_Schema_uri 2
646 * resultCount parameter to Sort Response (Amendment 1).
647 http://lcweb.loc.gov/z3950/agency/amend/am1.html
649 Support for SRW 1.0 over HTTP. This is an optional feature and
650 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
653 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
654 on the same port. SRW SearchRetrieveRequests are mapped
655 to bend_init,bend_search,bend_fetch,bend_close.
657 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
659 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
660 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
662 ZOOM connections are SRW based if schem http is used for hostname
663 in connect, e.g. z = ZOOM_connection_new("http://myserver");
664 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
666 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
667 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
668 distance=n, order=true/false, relation=le, prox unit=word. If
669 n is omitted, distance 1 is used.
671 Fixed problem with C compiler include path in wrong order.
673 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
674 on Solaris. Patch from Ko van der Sloot.
676 New MARC decode API. All new functions operate on a yaz_marc_t
677 handle. The most important new functions are: yaz_marc_create,
678 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
679 decode and destroy respectively. Decoder can produce formats
680 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
681 include/yaz/marcdisp.h.
683 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
684 to UTF-8, UCS-32, wchar_t or Latin-1.
686 * Prototypes for yaz_iconv_-functions moved to separate header
687 include/yaz/yaz-iconv.h.
689 Make a few private functions 'static' in unix.c. This prevents
690 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
692 For ZOOM connection, the options targetImplementation{Id,Name,Version}
693 are set when Init Response is received.
695 New function ZOOM_connection_error_x similar to ZOOM_connection_error
696 but returns diagnostic set as well.
698 New function yaz_strerror which is a portable wrapper for
699 strerror/strerror_r/GetLastMessage.
701 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
702 is returned for MARC. If type is "oai", then OAI MARC is returned.
704 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
709 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
711 Fix bad race conditions on SIGTERM and terminate gracefully in
714 Move retrieval (data1) module to Zebra since nobody seems to be
717 Add GRS-1 render for ZOOM using same format as yaz-client.
721 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
723 Fix broken ESpec handling in data1 module.
725 SGML reader parses comments and makes them part of the data1 tree.
727 Added several type casts so that YAZ compiles as C++ code.
729 ZOOM didn't handle PDU encoding failures properly.
731 Added more Bib-1 diagnostics (approved extensions).
733 GNU configure: better check for iconv.
735 More portable use of accept, getpeername. Check for socklen_t. Use
736 int/size_t if socklen_t is not defined.
740 PQF parser rejects bad queries - including those with extra
741 characters in them. PQF parser used to silently ignore that.
742 Cleaner API for PQF added, which allows you to get detailed
743 error information for bad queries (see yaz/pquery.h).
745 Fixed bug in ZOOM_record_get for type "database".
747 Implemented mini iconv library supporting conversions between
748 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
750 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
754 Fixed ZOOM C record cache so that preferredRecordSyntax and
755 elementSetName is used to check for already fetched records.
759 Added three members in bend_initrequest structure to facilitate
760 character set negotiation.
762 Fixed a bug in frontend server that could cause indefinite
763 loops under rare conditions.
765 Revised character set utilities (charneg.h) so that encoding
766 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
768 For PQF, directive @term <type> sets term type for Scan/Search.
769 Here <type> is general, string, numeric, null. The term type
770 is inherited - just like @attr.
772 New call odr_set_charset that sets character set conversion for
773 international-strings on a ODR stream. Prototype is:
774 int odr_set_charset(ODR o, const char *to, const char *from);
775 The InternationalString is still represented as C string in YAZ
776 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
777 won't). On the protocol level, you can use any encoding.
779 Support for UNIX sockets in ZOOM.
781 Solaris recv sometimes returns errno == ENOENT. It is treated as
782 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
784 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
785 both client and server. Code by Morten Bøgeskov.
789 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
790 that they can be used directly from Visual Basic. You must recompile
791 your windows APP if you're using ZOOM.
793 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
794 Commands "lang" and "charset" sets language and character set respectively.
795 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
796 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
798 Attributes from multiple CCL fields may be OR'ed rather than merged
799 using directive "@field or". Fields are still merged by default -
800 equivalent to "@field merge".
802 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
805 Fixed bug in zget for parameter ExtendedServicesResponse.
811 Added PQF feature: '@attr type=value' may be written as '@type=value'.
813 Client displays USR.1:SearchResult-1 (hits per term).
815 Additional Search Info for search in Generic Frontend Server.
817 Fixed CCL parsing of "field=s".
819 WIN32 installer - using the excellent NSIS software from nullsoft.
821 Fixed CCL parsing of "field = - <number>".
823 Added function yaz_marc_decode that decodes MARC for line mode
824 display or XML (similar to that used by JZKit).
826 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
827 Z39.50. But ISO/ILL was, however.
829 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
830 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
832 http://lcweb.loc.gov/z3950/agency/amend/am2.html
833 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
837 New YAZ client features: Command completion and new commands:
838 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
839 Code provided by Jacob Poulsen.
841 New call oid_trav, that visits all registered OIDs via callback.
843 Function ZOOM_record_get now returns const char pointer rather than
844 void pointer. It saves a lot of type casts.
846 For YAZ client, command "auth" now allows you to set authentication
847 in IdPass style. It is enabled when three tokens are given - order
848 is user, group and password.
850 Fix memory leaks in MARC record handling for ZOOM.
852 New option for YAZ client, -k <kilobytes> that sets
853 maximum record size. Similar to -k option for generic frontend
854 server and yaz-ztest.
856 More fixes for scan. Non-zero stepSize handled. OID's fixes.
858 Prefix query parser reports "fail" when bad attribute set is given.
860 Fix in MARC decoder. Proximity logging. Fix for attribute set
861 in scan handler for server. Patches by Shigeru Ishida.
863 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
866 Configure option --with-openssl=<dir> now works when a directory is
867 specified. Patch provided by Morten Bøgeskov.
869 New option for YAZ client, -u <auth>, that sets authentication.
871 ZOOM fix: error information was sometimes "missing", since error
872 was cleared/reset too when it shouldn't.
874 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
878 Scan for ZOOM API. New object ZOOM_scanset. New functions
879 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
880 ZOOM_scanset_destroy.
882 New ZOOM function, ZOOM_connection_last_event, that returns type
883 of last event (such as "receive data", "send data", "apdu received",
886 New ZOOM option, schema, that specifies schema for retrieval.
888 New CCL feature. Qualifiers can be aliases for one or more
889 other qualifiers (if more than one is given, OR is used).
891 ZOOM uses named result sets if target supports it.
893 Two new YAZ client commands: . (dot, which sources a script of YAZ
894 client commands), and ! (to execute shell command.). Implemented
897 Working on Debian packages.
901 YAZ client enables named result sets only if target supports it.
903 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
905 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
906 with key="host" to get same result.
908 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
909 Function Z3950_resultset_record(s) returns references to records
910 "owned" by resultset. To become owner use Z3950_record_clone.
912 Function z_ext_record handles Extended Services. Thanks to
917 CCL Parser fix: ignore token comma when dealing with and-lists.
919 Documentation updates for COMSTACK.
921 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
922 Changed prototype Z3950_records. For some functions, int parameters
923 were changed to size_t.
925 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
928 New MARC decode/display function, marc_display_exl, which properly rejects
929 non-ISO2709 records. YAZ client uses it.
933 Fix bug: local attribute set wasn't set correctly in PQF strings.
937 * Old Z39.50 codecs no longer supported.
939 Added ZOOM C binding. See http://zoom.z3950.org/
941 Renamed states for COMSTACKs to avoid confusion with events.
943 Implemented cs_look and proper cs_rcvconnect.
945 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
947 Configure detects POSIX threads on OpenBSD.
949 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
950 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
952 When error is returned from present handler, non-surrogate diagnostic
953 is returned in present response (and fetch handler is no longer called).
955 * Minor adjustments to pquery parser (PQF). Token characters may be
956 escaped by using backslash (C-style).
958 PQF parser allows string attribute values to be specified. For @attr,
959 non-numeric characters after the equal-sign are treated as strings
960 (e.g. @attr 9=title).
962 CCL trunction character may be defined (@truncation in file)
964 * function zget_ExtendedServicesRequest sets waitAction to
965 waitIfPossible (was wait).
967 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
970 CCL operator names may be set in field definition files (CCL_bibset).
971 See ccl/bib1 for an example.
973 Fixes in ASN.1 compiler for C++ compatibility.
975 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
976 and "op_or" to avoid conflict with C++.
978 Fixed problem with GNU readline detection on Redhat 7.0.
980 Added step-size for Scan backend handler.
982 Fixed bug that made the frontend server crash when no attribute
983 set was specified for scan.
985 Front-end server automatically switches to original working directory
986 when installed as an NT service. Previously -w had to be specified to
989 Added extended attributes for retrieval module (data1), so that data1
990 records carry d1_readXML/SGML attributes. d1_read also supports
991 null-data rules ( <tag/>)
993 On UNIX when POSIX threads are available, a separate library libyazthread
994 is created. Programmers should link with that library and the yaz library
995 when using threads. The reason for the split was that some applications
996 on Linux, such as Apache, doesn't work well when using shared objects that
999 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1000 (or any frontend server) in SSL mode by specifying ssl: followed by
1001 address. Only tested on UNIX.
1003 Added feature for CCL module. Virtual structure s=al or s=ol generates
1004 and-list and or-list respectively instead of phrase search.
1008 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1009 log_mask_str. This was done to avoid name conflicts with other libraries
1010 (such as other PHP extensions).
1012 Added raw OID member for preferred record syntax (request_format_raw)
1013 and returned record syntax (output_format_raw) for backend fetch method.
1015 Config file yaz-config now accepts options so that it returns specific
1016 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1018 Shared library support for UNIX using GNU libtool.
1020 * Modified backend interface. Request/Response struct's replaced by
1021 one read/write C struct. For example bend_fetchrequest and
1022 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1023 Every handler - even search has to be registered in bend_init
1024 handler. This means that the YAZ library no longer refers to
1025 external functions and it makes it possible to make the whole
1026 thing a single DLL/SO.
1028 Added Segment handler for backend server.
1030 Added Zmbol/Zebra administrative functions to YAZ client.
1032 Threaded frontend server on UNIX (when POSIX Threads are available).
1033 Starting the server with option -T enables multi-threading.
1037 Added configure option --enable-comp/disable-comp to control use
1038 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1039 located in sub directory asn.
1041 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1042 in ${exec_prefix}/bin along with the other programs yaz-client and
1045 GNU automake used to maintain makefiles.
1047 Added several OID's.
1049 Changed retrieval module so that we can load records with no abstract
1050 syntax defined. Tagpaths in these records are fully composed of string
1053 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1057 On UNIX, the generated makefile now supports a proper 'make install'.
1058 The prefix can be set via GNU configure to set the install location
1059 (default is /usr/local).
1061 * YAZ programs client and ztest were renamed to yaz-client and
1062 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1063 locations, such as /usr/bin,/usr/local/bin,etc.
1065 * YAZ Header files were moved from include to include/yaz. YAZ Header
1066 files are referred to as include <yaz/log.h> rather than <log.h>.
1067 The YAZ include path (-I ..) is therefore the same as before. Programmers
1068 should update their #include statements or use -Ipath/include/yaz
1069 instead. The main motivation for doing this change is that YAZ header files
1070 can be installed in "standard" locations /usr/include,/usr/local/include
1071 without introducing conflicts, since ALL YAZ header files are stored
1072 in subdirectory yaz (under /usr/include for example).
1074 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1075 rather than project/workspace files. We switched because project files
1076 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1079 Changed name of logging function, logf, to yaz_log, to prevent name
1080 clash with some math-log functions. The YAZ header log.h defines logf
1081 to yaz_log (#define) so there should be no incompatibilities by this
1084 Added bend_start/bend_stop handlers for server. These handler are
1085 called on start/stop of server. For windows they are called whenever
1086 a service is started/stopped.
1088 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1089 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1090 in util/yc.tcl. The auto-generated C code structures are, in a few
1091 cases, incompatible with the old decoders. There are differences in the
1092 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1093 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1094 The preprocessor variable ASN_COMPILED is defined when the compiled
1095 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1096 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1097 wish to use the old encoders/decoders you can specify --disable-yc
1100 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1101 version so that it supports both new - and old version of DB Update
1103 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1104 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1105 change. The name parameter can be set to 0 in which no name is specified
1106 for the construction. The macros odr_implicit and odr_explicit sets name
1107 parameter to zero for the construction involved. New macros
1108 odr_implicit_tag and odr_explicit_tag are similar to the others,
1109 except that a name parameter is added. For programmers' that don't use
1110 ODR they probably only need to change the call to z_APDU and z_External.
1112 Added access control facility by interfacing the TCP wrapper library.
1113 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1114 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1115 name of the daemon and enables the access control as specified in
1116 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1118 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1119 den Dool <H.M.vdnDool@kub.nl>.
1121 Added reference ID parameter to most functions in server API - refer
1122 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1124 Changed name of ccl library to libccl.a (was ccl.a).
1126 Fixed bug in decoder for Explain (Category TargetInfo).
1128 Added support for GNU readline in client. Thanks to Jacob Poulsen
1129 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1131 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1132 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1133 IMPLEMENTATION! This change was made to the development version before
1134 the ZIG decided to retract the amendment. If any users MUST be
1135 compatible with the original Update definition, PLEASE CONTACT US, and
1136 we will include a separate definition corresponding to the old Update
1137 ES. Note that because of the change to the ASN.1 of the
1138 TaskPackageRecordStructure we cannot define a single structure that
1139 will support both versions.
1141 * Added const modifier to buffer parameter for some ODR/BER encoding
1142 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1143 completeWAIS, odr_dumpBER.
1145 Fixed bug in client.c which caused a crash when a scanResponse didn't
1146 contain positionOfTerm.
1148 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1149 * will cause an error in a client if a non-YAZ target sends both a
1150 * list of Scan entries and non-surrogate diagnostics.
1152 Retrieval module enhancements. Tag sets may be typed in the reference
1153 to it. From the .abs-file the "tagset" directive takes a third optional
1154 integer type for the tag set referenced. From a .tag-file the "include"
1155 directive takes a third optional type as well. The old "type" directive
1156 in the tag set itself is still recognized but acts as the default type
1159 Backend interface change. Individual Scan terms returned from bend_scan
1160 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1161 in include/backend.h.
1163 Retrieval module enhancements. Multiple tag sets and attribute sets may
1164 be specified in abstract syntax specs. Revised the error/warning for
1165 logging messages reported by the retrieval module when reading the
1168 Object Identifier system (oid_..) changed. The API is backwards
1169 compatible but the oid-routines now allocates new OID's when needed.
1170 Raw OID's may be specified in oid_getvalbyname.
1172 YAZ now uses GNU configure to generate Makefile(s).
1174 * Minor changes in some of the member names of DeleteResultSetRequest and
1175 DeleteResultSetResponse. See include/proto.h.
1177 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1178 and added member 'languages' in TargetInfo (which was missing).
1180 Changed the way attribute sets are handled in the retrieval
1181 module. These are now cached, just like the abstract syntaxes
1184 Changed YAZ so that it links with compiled ASN.1.
1186 Added Explain-schema definitions and mapping routines. The following
1187 Explain categories have been implemented: AttributeDetails,
1188 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1190 Fixed minor bug in Windows version of Server Library.
1192 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1194 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1196 Added EXTERNAL: UNIverse Resource Report (non-standard).
1198 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1199 ENUMERATED and SET OF.
1201 * Added 'const' to some of the char pointer arguments for the
1202 functions, data1_read_node, data1_getelementbytagname,
1203 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1206 Fixed bug in data1_insert_taggeddata - the last_child member of
1207 parent wasn't initialised.
1209 * Changed data1_read_record and data1_read_node so that the supplied
1210 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1211 doesn't refer to any parts of the "SGML"-buffer.
1213 Fixed bug in server library (Windows version of statserv_remove).
1215 * Changed code so that it compiles as C++. The type definition
1216 of Odr_fun which is a member of Odr_arm was changed. The result is,
1217 that an explicit typecast is needed for the fun pointer when
1218 using Odr_arm - as in:
1219 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1221 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1223 Implemented the new structured date and time definition as approved
1224 by the ZIG. Added schemaId element to the specificTag in Espec-1
1225 (also approved at the last ZIG). Thanks to RVDM.
1227 Added some Object identifiers (RVDM).
1229 Changed the Update Extended Service (RVDM).
1231 Added command "refid" to client which specifies referenceId for
1232 the following requests.
1234 Implemented extended service handling for server. See ztest.c
1235 for an example as well as backend.h. New handlers are registerd
1236 in the Init handler.
1238 * Changed interface for sort in server.
1240 Added new members to statserv_options_block. It allows a server
1241 to read options from another source than just the command line. Thanks
1242 to Charles Woodfield.
1244 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1245 renamed to zboolean. Some C++ compilers complained about the name.
1247 Minor changes to gils.abs. Added index 's' (sort) on title
1248 and date/time-last-modified.
1250 --- 1.4pl2 1998/1/30
1252 Fixed bug in server library regarding inetd mode (-i). This bug
1253 was introduced by release 1.4.
1255 --- 1.4pl1 1998/1/29
1257 Added sort facility in client and backend server interface.
1259 Fixed problem with dependencies in Makefile(s).
1261 Fixed bugs for encoders/decoders of extended services and
1264 Implemented sub-tree feature for schemas. Sub-trees are
1265 referenced in *.abs-files. See explain.abs for an example
1266 of the use of this feature.
1268 Modified bib1.att; local attributes for ANY didn't include
1269 ANY itself (only affects use of the retrieval module).
1271 Fixed bug in plain SGML reader in function data1_read_node:
1272 tags with prefix "var" was incorrectly interpreted as variants.
1274 Added feature "sub-schemas" to enable references to - and definitions
1275 of - group of elements.
1277 * Removed member parent from type data1_element (in data1.h).
1279 Implemented function odr_nullval() that returns the value of
1282 * Removed member num_children from data1_node (in data1.h).
1284 Made NT service interface part of the server library. The
1285 function statserv_main uses the NT service when required and
1286 calls the statserv_start / statserv_close routines.
1288 Routine zget_SearchRequest and zget_PresentRequest fills
1289 resultSetName/Id member with "default" instead of "Default".
1291 Fixed memory leak in server. Request queue member wasn't freed.
1293 Fixed nmem_exit so that memory is freed.
1297 Revised the CCL parser utility to be thread safe.
1299 Added function, oid_ent_to_oid, to replace the function
1300 oid_getoidbyent, which is not thread safe.
1302 * Added nmem_init and nmem_exit to initialize and release
1303 NMEM resources. Function nmem_init should be called once in the
1304 initial thread before NMEM/ODR is used. statserv.c and client.c
1305 have been changed accordingly. The change was necessary to make
1306 NMEM thread safe. The NMEM memory pool is shared amongst threads
1307 in a process. Unix-based applications will still work fine without
1310 Added NT Services interface for the the Z39.50 (statserv) Server.
1311 Refer to the ztest.c source on the usage.
1313 Windows 95/NT port using MSVC5.0. Project files are included in the
1316 * Defined new 'global' handle for the retrieval (data1) system. The
1317 new handled, data1_handle, describes the state of the data1 system.
1318 This handle is passed as first argument to virtually all
1319 data1 related routines. The functions data1_create and data1_destroy
1320 creates and destroys a data1 handle respectively.
1322 Added ODR encode stream member to all backend request structures
1323 init, search, scan etc. This stream should be used to allocate all
1324 memory used for the response when thread safe operation is needed.
1326 Changed the comstack utility, cs_addstr, to be thread safe. The
1327 returned hostname string returned by the function is now part the
1330 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1331 function. The cs_straddr takes a COMSTACK handle as argument, so this
1332 function must be used after cs_create and before bind/connect.
1333 This function is thread safe.
1335 Moved test server to 'ztest' directory - generic server code still
1336 in 'server' directory.
1338 Made prefix query (pquery.c) utility thread safe.
1340 Added new function modifier YAZ_EXPORT to 'export' public DLL
1341 functions when using windows (see include/yconfig.h).
1343 Added definitions to the OID database (util/oid.c) (RVDM).
1345 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1347 Added call to ccl_rpn_delete in client program.
1349 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1350 release of RPN structure.
1352 Added support for C++, headers uses extern "C" for public definitions.
1353 With input from RVDM.
1355 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1356 Thanks to Ronald van der Meer (RVDM).
1358 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1360 Added support for private extensions to the OID database
1361 (oid_setprivateoids()). Thanks to RVDM.
1363 Added optional, physical ANY (key replication)
1365 Fixed null-reference problem in GRS-1 output filter.
1367 Proximity operator added to Prefix Query Format (PQF).
1369 In test client command "base" accepts multiple databases.
1371 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1375 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1377 Smallish bug-fixes in the new encoders/decoders (explain).
1379 Bug fixed in DeleteRequest.
1381 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1383 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1385 Added SOIF syntax (using private OID for now) to retrieval module and client.
1387 Added Update extended service.
1389 Added SearchResult-1 additional info structure.
1391 Added optional CCL (ISO8777) interpreter as separate module. Available
1394 --- 1.2 1996/6/10 (1st anniversary release)
1396 Added Summary record syntax. Lightly tested.
1398 Added OPAC record syntax. Untested.
1400 Added ResourceReport service encoders/decoders. Untested.
1402 Fixed bug in z_Unit - wrong tagging on unitSystem.
1404 Fixed bug in the DiagRecs decoder.
1406 Added options for max PDU size and session timeout to frontend-server.
1408 Added documentation of query-language parsers and other supporting utilities.
1410 [frontend-server] Added Attribute set to the bend_scanrequest API.
1412 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1413 surrogate diagnostics were generated.
1415 [retrieval] Allow multiple local values for attribute.
1417 [retrieval] Allow multiple attributes per element in .abs files. index type.
1419 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1421 --- 1.1pl2 1996/4/10
1423 Minor changes, mostly specific to Zebra's requirements (retrieval)
1427 Repaired bug in frontend server when running multiple listening
1428 endpoints in dynamic mode.
1430 z_External() now won't break if a known, ASN.1 value comes encapsulated
1431 in an octet-string. The value will pass through unmodified in an Odr_oct.
1433 Added a bit of code to the demo client to decode & display
1434 ASN.1-structured records represented in the octet-aligned branch of
1435 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1437 Added z_ext_getentbyref() to the ASN module. Doc updated.
1439 * Completed the SCAN definition in the ASN module. This may break SCAN
1440 code based on older YAZ-versions at compile-time. The fix is easy -
1443 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1444 under the SCAN definition. Remember to initialize this, server-people.
1446 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1447 that this does not extend to ODR and ASN.
1449 Comstack allows insertion of established socket (primarily for
1450 inetd-operation of servers). Doc updated.
1452 Front-end server can now start from the inetd in TCP mode. Doc
1455 --- 1.0pl4 1996/1/24
1459 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1460 the rank and record number.
1462 Adjustments to the frontend server.
1464 Fixed diagnostic BER dumper. It ignored the file argument.
1468 Various changes to retrieval module.
1470 Changed the union discriminators of the protocol files from enums to
1471 ints paired with #defines.
1473 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1476 *Changed operator in the RPN structure to 'roperator', again to avoid a
1479 Fixed problems in Explain decoders/encoders.
1481 --- 1.0pl2 1995/12/6
1483 Memory bug in log module fixed.
1485 --- 1.0pl1 1995/12/5
1487 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1489 Bug in Explain DatabaseInfo module fixed.
1491 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1495 The shift to v1.0 signals that we now consider the *core* functionality
1496 of YAZ reasonably stable (the core being more or less equivalent to
1497 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1498 tested (Explain not at all - though that will happen soonish).
1500 Minor changes to code to support Windows port.
1502 Various minor changes after we're getting to use GRS-1 & co. more.
1504 Added Espec-1 format.
1506 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1507 of the protocol and it cannot be selected when encoding (maps into 'string'
1508 when decoding). Needed to talk to some servers.
1510 Demo client can request simple element set names.
1512 Added Diagnostic Format encoders/decoders.
1514 Added simple Close handling to frontend server (no hooks for resource
1515 reporting yet), and demonstration client.
1517 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1519 --- 1.0b3 1995/08/24
1521 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1522 handled incorrectly when records were requested in the searchResponse. This
1523 will only affect you if you use the frontend-server.
1525 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1526 Test-client will ask for and print GRS1. Ztest will return dummy records
1529 Added Explain encoders/decoders to the service-level API. Untested.
1531 Added Extended Services: Item Order encoders and decoders to the Service-
1532 level API. Untested. We could use a recent copy of the pertinent bits
1533 of the ILL protocol to add those bits.
1535 Added diagnostic format 1 encoders/decoders to the service-level API.
1538 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1539 odr_cons.c, which causes a more correct output.
1541 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1542 was always set to 0 when no records were requested in the searchRequest.
1544 * Added better external-handling. This shouldn't harm old code that
1545 *encodes* externals. It can break code that looks for a
1546 'single-ASN1-type' representation, since those types that are known
1547 are now decoded immediately. Look at the SUTRS sample code in
1548 seshigh.c and client.c. Documentation updated.
1550 Handling of structured records in bend_fetchresponse. Length -1 marks
1551 structured record, type is deduced from format field.
1553 --- 1.0b2 1995/06/27
1554 Fairly quick maintenance release to add SUTRS support.
1556 Fixed handling of SUTRS records in the demonstration client.
1558 * Added format field to the bend_fetchrequest and bend_fetchresponce
1559 structures of the backend API (frontend server). When the record is
1560 returned, the value of the format field is mapped to an OID. The
1561 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1562 of the record. The special value VAL_NONE in the bend_request means
1563 that no specific format was requested by the client. Documentation
1564 updated accordingly. Test server (ztest) will return a fixed dummy
1565 SUTRS record if your client requests SUTRS.
1567 Documentation updated accordingly.
1569 You can now set external libraries and RANLIB support in the top-level
1573 First public release.
