1 Possible compatibility problems with earlier versions marked with '*'.
3 Fixed bug #307: It was impossible to specify indefinite/no timeout
4 for ZOOM_event. Special timeout value -1 now means indefinite timeout
7 Added support for multiple languages and charsets to be specified in
8 ZOOM. Each charset/language is separated by a blank. If negotiation is
9 in effect in init-response, Option
10 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
11 Code based on patch by Vasiliy Osadchuk.
13 Fixed bug #306: infinite recursion that occurred when calling
14 yaz_log_level_init as the first call (before other log level or
17 Fixed bug in scan handling in front end server: if preferred-Position-In-
18 Response was non-present, a NULL pointer referece was performed.
22 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
23 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
24 now defined for all those error codes. So instead of putting 109 in
25 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
26 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
28 Modified the yaz-marcdump utility to skip garbage bytes between MARC
31 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
33 Program yaz-client now exits and produces an error message if multiple
34 Z39.50 servers are specified on the command line (none or one allowed
37 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
42 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
44 Fixed bug #272: Preserve spacing for CCL terms.
48 Added support for virtual hosts and multiple backend servers for
49 the YAZ frontend server. The configution is XML based and
50 support specificition of CQL to RPN mappings and explain information.
51 See section "Virtual Hosts" in the YAZ manual.
53 Extended OPAC display utility. OPAC display utility renders
54 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
55 to supplement yaz_marc_decode_wrbuf.
57 Fixed a bug in MARC decoder that could caused it to crash for some
58 invalid MARC records. More diagnostics and warnings where added in
59 XML output (warnings, etc are stored in comments).
63 Fixes for UNIX domain sockets. Bug #261.
65 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
67 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
68 Added yaz_marc_subfield_str which defines subfield lead string which is
69 used in YAZ_MARC_LINE format. Default string is blank+$. Added
70 yaz_marc_endline_str which defines end of fields string used in
71 YAZ_MARC_LINE format. Default string is newline.
73 Experimental support for MarcXChange. This format can be produced
74 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
75 http://www.bs.dk/standards/MarcXchange.xsd
77 Added yaz-client commands scansize that sets maximum number of
78 entries to be returned by scan.
82 Added support for SRW scan in yaz-client and Generic Frontend Server.
84 * Added whereInList member to SRW Scan Term.
86 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
88 Fixed NMEM system to return aligned blocks on the smallest boundaries
89 that are suitably aligned for all possible types on the particular
90 architecture YAZ is being built for.
94 Fixed numerious warnings that was issued with newer versions of GCC.
96 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
97 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
100 Make YAZ Generic Frontend Server slightly faster.
102 Enhance (and reduce) logging for Generic Frontend Server.
104 Revert YAZ log system so that it flushes every write operation
105 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
107 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
108 instead of LOG_, due to name clash with syslog(3). LOG_ are still
109 present. New applications should define YAZ_USE_NEW_LOG=1 - this
110 will effectively disable old definitions.
112 --- 2.0.28 2004/11/09
114 Added yaz_log_time_format which specifies log format using
117 Added yaz_log_module_level which returns mask for a module. Value
118 is non-zero mask a if module is enabled; zero if disabled.
120 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
121 in include/yaz/cql.h.
123 Fixed bug #176: Dont throw diagnostics on empty SRU args.
125 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
127 Fixed bug #172: RPM builds does not enable SSL.
129 Doxyfile.in part of dist. Doxyfile generated by configure.
131 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
132 are given and the corresponding component does not exist.
134 Extend CCL documentation in YAZ reference. Describe r=r.
136 --- 2.0.26 2004/10/01
138 Fixed MARC->MARCXML conversion to properly deal with
139 fields, subfields, indicators having non-ASCII characters.
141 Fixed MARC->MARCXML conversion so that ASCII control characters
142 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
145 Added YAZ GFS support for conversion from Z39.50 surrogate
146 diagnostics to SRW surrogate diagnostics.
148 Bug fix: YAZ GFS did not return schema in explainResponse.
150 --- 2.0.25 2004/09/30
152 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
153 now converts recordSchema to elementSetName as well as schema URI.
155 Fixed bug in COMSTACK that prevented HTTP request packages from being
158 --- 2.0.24 2004/09/29
160 Added CCL facility r=r "range" which is similar to r=o "ordered" but
161 does not require white-space before and after the dash in a range, e.g.
162 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
165 Fixed a few AC_TRY_LINK configure tests that did not operate properly
166 due to new GCC removing "redundant" code.
168 Added yaz-client commands scanpos and scanstep that sets preferred
169 position and step-size for scan.
171 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
173 Added CCL utility ccl_qual_buf which parses one or more CCL
174 spec lines in a buffer.
176 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
177 of name and value - ignoring empty lines and comments.
179 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
181 Added odr_get_element_path which returns current element path for an
182 ODR handle. This utility is useful in error handling or user-defined
185 Added ODR_PRINT utility odr_set_stream which is is a more generic
186 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
187 to a write function and pointer to close function. The close function - if
188 non-NULL - will be called during odr_destroy.
190 Fixed bug in CCL parser where truncation char was not removed from
191 right side when truncation=both was in effect.
193 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
196 --- 2.0.23 2004/08/11
198 Fix buffer overrun in CQL parser when dealing with proximity (%).
200 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
201 to UTF-8/UCS conversion is now only based on codetables.xml.
203 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
205 --- 2.0.22 2004/08/06
207 Add support for more "commit changes" in ZOOM (uses Extended Services).
209 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
212 Yet another small fix for configure of SSL.
214 --- 2.0.21 2004/05/14
216 Fix SSL libs for configure when --with-openssl=DIR is given.
218 --- 2.0.20 2004/05/10
220 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
222 SSL comstack now uses yaz.pem certificate file on server side
223 by default. Certificate filename can be configured by calling
224 comstack function cs_set_ssl_certificate_file before cs_bind is used.
226 Fix bug regarding multiple calls to ZOOM_connection_connect.
228 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
230 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
231 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
233 ZOOM now allows inspection of X509 peer certificate for verification.
234 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
236 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
237 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
238 as "modular" but it simplifies things.
240 Added cs_get_peer_certificate to that returns peer X509 PEM.
242 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
243 NULL if SSL is unavailable.
245 Documentation about MARC decoding tools.
247 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
249 --- 2.0.19 2004/03/30
251 Rename CHANGELOG to NEWS to follow GNU style packing.
253 Fix bug with missing initialization of member in init_diagnostics.
254 This bug affects threaded version of GFS server.
256 --- 2.0.18 2004/03/20
258 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
261 Ensure zlib.dll is packed with Windows install.
263 --- 2.0.17 2004/03/17
265 Fix encoding of xsd:string to use text instead of CDATA.
267 Fix endless loop in CQL parser with unbalanced ".
269 Use a more compact way to store MARC-8 conversion tables.
271 --- 2.0.16 2004/03/16 Debian only
273 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
276 Update CQL parser to use new CQL 1.1 modifiers for booleans and
281 --- 2.0.15 2004/03/01
283 Another fix for decoding of XML packed records.
285 --- 2.0.14 2004/02/25
287 Fixes for Chunked encoding. White space not ignored after length spec.
289 Update NS and use default NS for SRW diagnostic elements.
291 --- 2.0.13 2004/02/23
293 Implement ZOOM_resultset_cache_reset which resets record cache.
295 Implement ZOOM_resultset_sort which sorts a result set.
297 Implement chunked HTTP transfer.
299 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
301 --- 2.0.12 2004/02/16
303 Added member 'schema' to bend_explain_rr structure so that backend
304 can specify explain record identifier. Defaults to Zeerex 2.0.
306 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
308 --- 2.0.11 2004/02/16
310 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
313 Added init command for yaz-client which sends "extra" init request.
315 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
316 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
318 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
320 Make ZOOM error code for "invalid query".
322 Fixed compilation for SSL which wasn't properly enabled for all platforms.
324 --- 2.0.10 2004/02/05
326 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
329 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
331 Added option -p <file> to make Generic Frontend Server to write PID file.
333 Added option -D to put Generic Frontend Server in background on its own.
335 Make ZOOM C recognize option "password". If unset, "pass" is used
336 (for backwards compatibility).
338 Fixed a bug in Generic Frontend Server that could make it crash if a
339 client sets characterSetNegotation bit, but didn't pass negotiation stuff
342 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
343 Must be issued before open, in order to be in effect.
345 --- 2.0.9-6 2004/01/12 Debian/Windows
347 Make the SRU server more picky WRT unknown params, etc.
349 Bug fix: ZOOM scan response didn't return displayTerm - when present.
351 New YAZ client command, options, that sets Z39.50 options.
353 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
354 options from a string of tokens (one token for each option bit).
356 Update SRW diagnostic code messages.
358 --- 2.0.9-5 2004/01/07 Debian/Windows
360 Handle user defined stylesheet for SRW/SRU.
362 --- 2.0.9-4 2004/01/06 Debian/Windows
364 Fix bug in decoding of Content-Length.
366 --- 2.0.9-3 2004/01/06 Debian/Windows
368 Fix a bug with decoding of XML packed records.
370 --- 2.0.9-2 2004/01/05 Debian only
372 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
374 Fix bug in SRW/SRU diagnostics decoding.
378 Fixed bug in Generic Frontend Server which could drop records exceeding
379 preferred message size. Reported and fixed by Irina Dijour.
381 Fixed calculation of package size for structured records in Generic
382 Frontend Server. Reported and fixed by Irina Dijour.
384 Fixed namespace for SRW/SRU diagnostics.
386 Fixed SEGV in yaz-client that occured for HTTP connection errors.
390 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
391 this version is incompatible with version 1.0 and older YAZ SRW/SRU
394 CQL changes to reflect recent changes to the specification:
395 * Documentation talks about context sets instead of index sets.
396 * Documentation talks about indexes instead of qualifiers.
397 * The CQL-to-PQF transformer's configuration file now uses
398 "index.set.name = <attributes>" instead of the old form
399 "qualifier.set.name = <attributes>". (Both forms are still
400 understood but the latter is deprecated.)
401 * CQL terms with no explicit index specified are now interpreted as
402 cql.serverChoice instead of srw.serverChoice (which of course
403 behaves exactly the same.)
407 MARC conversion can now generate ISO2709 output in another
408 character set. yaz-marcdump uses this facility if you invoke it
411 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
412 functions from there can be used from C++.
416 Frontend server now transfers memory from decoded packages to stream
419 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
420 references to show up.
422 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
423 the ZOOM Abstract API. The older names for the same options are still
424 also supported for the benefit of old applications.
426 ZOOM-C supports "implementationId" and "implementationVersion" options
427 to go along with "implementationName". These allow the user code to
428 specify identification strings to be sent to servers.
429 Add OID for the new ExtLite attribute set.
431 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
432 as requested/supplid by Ere Maijala <ere@atp.fi>
434 For generic frontend server, reverse the order of
435 "toolkit-supplied / application-supplied" strings sent as implementationId,
436 Name and Version. Also, remove the spaces around the slash. This brings
437 the GFS in line with the behaviour of ZOOM-C on the client side.
439 Add function ZOOM_scanset_display_term.
441 yaz-client shows scan displayTerm if present.
443 Utility yaz-iconv is now installed by default along with the man page
446 Extend configure check for OpenSSL to use pkg-config where available (such
449 Incorporate patch by Morten Bogeskov which allows a Unix file socket
450 server to specify uid/gid/mask for socket using the format
451 unix:[user=uid,][group=gid,][umask=mask,]file=path
452 If file= is omitted the existing format is assumed, e.g.
454 in which case the mask is 0666 (rw for everybody).
456 Major restructure of YAZ source. All source in libyaz is in src directory.
457 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
458 util (utility programs such as ASN.1 compiler, yaz-marcdump).
460 Added man page for utility yaz-marcdump (used to be called marcdump).
461 yaz-marcdump is installed by 'make install'.
463 Fixed a memory leak in Generic Frontend Server that occurred when decoding
464 of incoming package failed.
466 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
468 Change prototype of odr_perror: add const to message string.
470 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
472 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
473 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
474 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
475 DNS lookup. There should not be any compatibility problems with this
476 assuming that blocking=1 or 0 is used.
478 Fix bad reference in UNIX comstack in function cs_addrstr.
480 Fix for compilation on AIX.
482 The generic front-end server (server/seshigh.c) now supports returning
483 Init diagnostics to the client in User-information-field, in
484 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
489 Allow any CQL relation (not just all,any,exact,scr).
491 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
492 that features the same UI.
494 Implemented command update0 in YAZ client which is equivalent to
495 update but uses old of Ext Update ASN.1.
497 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
498 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
499 Previously no OID was used for this info.
501 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
502 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
503 returns 'malformed search term' otherwise.
505 SortResponse member resultCount now set to NULL in sort handler of
508 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
511 Add three new utility functions for translating OIDs between various
512 formats -- symbolic name such as "Usmarc", minus-1-terminated int
513 arrays and dotted strings such as "1.2.840.10003.9.5.1":
514 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
515 char *oid_to_dotstring(const int *oid, char *oidbuf);
516 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
518 Reverted modifications for ES Update definition for z_IU0Update
519 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
520 is back to YAZ 2.0.2.
522 String value attributes for CCL parser.
524 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
525 which their FirstSearch server returns in Init responses, sometimes
526 carrying useful diagnostic information when Init fails. This has the
527 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
528 "z39.50/oclcui.asn", where its definition is somewhat different from
529 what OCLC document on their web-site, as required to interoperate with
532 Support for anonymous authentication in yaz-client. Use the command
535 * Fix the OID of the Index Data-local "admin" Extended Service from
536 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
537 the 1000, which indicates a locally-defined OID, was a mistake.
541 Fix CCL directive @case handling so that it affects string match for
542 both CCL keywords and qualifiers.
544 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
545 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
546 Decoder has been updated with ASN.1 changes as listed in
547 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
548 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
549 z_IUUpdate, remains unchanged.
551 ZOOM_record_get may now return a record in a specific character set.
552 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
553 "from" is the character set of record as returned by target. "to" is
554 the character set to be returned. If omitted, "to" is UTF-8.
556 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
558 New ODR utility, odr_getelement, which returns name of element for
559 which encoding/decoding failed.
561 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
562 in cases where a required element was omitted.
564 Bug fix: some MARC8 sequences were not converted.
566 New ZOOM option "step" which specifies number of records to be
567 retrieved in one chunk. Used in conjunction with "start" and "count".
569 SRW support for yaz-client. Use scheme http: to use it, e.g.
572 yaz-client no longer does (un)intelligent character set conversions
573 by default. Can be enabled with charset and marc_charset commands.
575 xmalloc trace fix for 64-bit systems such as DEC alpha.
577 Solaris 2.6 compile fix.
579 New function, cql_strerror() translates SRW error codes, as returned
580 by cql_transform_error(), into human-readable English strings. Used
581 in yaz-client diagnostics when appropriate.
583 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
584 converts it into a type-1 query which is sent to the server. This
585 makes CQL available for use with all Z-servers, as opposed to the tiny
586 minority that can handle CQL queries themselves.
590 New Debian package layout similar to the Redhat Package layout.
592 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
593 and search result respectively.
597 Redhat package is now several packages: libyaz (runtime libraries),
598 libyaz-devel (development and documentation, and yaz (utility programs).
599 Package spec file by Morten Bøgeskov.
601 New member 'schema' in struct bend_fetch_rr which the name of requested
602 schema (SRW/SRU) for record (or NULL if none was given). The fetch
603 handler MAY set this to reflect the schema of the returned record.
605 New member 'display_term' in struct scan_entry. GFS now sets member entries
606 and allocates scan entries to be filled by user scan handler. In previous
607 version, entries member was allocated by the scan handler. That still works,
608 but the GFS will ignore member display_term - assuming it was NOT set by
609 the handler. The fact that the GFS now allocates the entries both allows
610 for new members and makes a scan handler easier to write.
612 Fix CQL lex buffer overflow.
614 SRW/SRU recordPacking. For SRW default recordPacking is string. For
615 SRU default recordPacking is string.
617 SRU protocol support for frontend server.
619 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
621 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
623 Added scan for the ZOOM shell (zoomsh).
627 * String Identifers for Schemas (Amendment 5).
628 http://lcweb.loc.gov/z3950/agency/amend/am5.html
629 Old definition for schema
630 Odr_oid *schema; /* OPT */
635 Z_InternationalString *uri;
636 #define Z_Schema_oid 1
637 #define Z_Schema_uri 2
640 * resultCount parameter to Sort Response (Amendment 1).
641 http://lcweb.loc.gov/z3950/agency/amend/am1.html
643 Support for SRW 1.0 over HTTP. This is an optional feature and
644 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
647 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
648 on the same port. SRW SearchRetrieveRequests are mapped
649 to bend_init,bend_search,bend_fetch,bend_close.
651 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
653 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
654 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
656 ZOOM connections are SRW based if schem http is used for hostname
657 in connect, e.g. z = ZOOM_connection_new("http://myserver");
658 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
660 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
661 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
662 distance=n, order=true/false, relation=le, prox unit=word. If
663 n is omitted, distance 1 is used.
665 Fixed problem with C compiler include path in wrong order.
667 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
668 on Solaris. Patch from Ko van der Sloot.
670 New MARC decode API. All new functions operate on a yaz_marc_t
671 handle. The most important new functions are: yaz_marc_create,
672 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
673 decode and destroy respectively. Decoder can produce formats
674 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
675 include/yaz/marcdisp.h.
677 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
678 to UTF-8, UCS-32, wchar_t or Latin-1.
680 * Prototypes for yaz_iconv_-functions moved to separate header
681 include/yaz/yaz-iconv.h.
683 Make a few private functions 'static' in unix.c. This prevents
684 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
686 For ZOOM connection, the options targetImplementation{Id,Name,Version}
687 are set when Init Response is received.
689 New function ZOOM_connection_error_x similar to ZOOM_connection_error
690 but returns diagnostic set as well.
692 New function yaz_strerror which is a portable wrapper for
693 strerror/strerror_r/GetLastMessage.
695 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
696 is returned for MARC. If type is "oai", then OAI MARC is returned.
698 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
703 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
705 Fix bad race conditions on SIGTERM and terminate gracefully in
708 Move retrieval (data1) module to Zebra since nobody seems to be
711 Add GRS-1 render for ZOOM using same format as yaz-client.
715 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
717 Fix broken ESpec handling in data1 module.
719 SGML reader parses comments and makes them part of the data1 tree.
721 Added several type casts so that YAZ compiles as C++ code.
723 ZOOM didn't handle PDU encoding failures properly.
725 Added more Bib-1 diagnostics (approved extensions).
727 GNU configure: better check for iconv.
729 More portable use of accept, getpeername. Check for socklen_t. Use
730 int/size_t if socklen_t is not defined.
734 PQF parser rejects bad queries - including those with extra
735 characters in them. PQF parser used to silently ignore that.
736 Cleaner API for PQF added, which allows you to get detailed
737 error information for bad queries (see yaz/pquery.h).
739 Fixed bug in ZOOM_record_get for type "database".
741 Implemented mini iconv library supporting conversions between
742 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
744 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
748 Fixed ZOOM C record cache so that preferredRecordSyntax and
749 elementSetName is used to check for already fetched records.
753 Added three members in bend_initrequest structure to facilitate
754 character set negotiation.
756 Fixed a bug in frontend server that could cause indefinite
757 loops under rare conditions.
759 Revised character set utilities (charneg.h) so that encoding
760 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
762 For PQF, directive @term <type> sets term type for Scan/Search.
763 Here <type> is general, string, numeric, null. The term type
764 is inherited - just like @attr.
766 New call odr_set_charset that sets character set conversion for
767 international-strings on a ODR stream. Prototype is:
768 int odr_set_charset(ODR o, const char *to, const char *from);
769 The InternationalString is still represented as C string in YAZ
770 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
771 won't). On the protocol level, you can use any encoding.
773 Support for UNIX sockets in ZOOM.
775 Solaris recv sometimes returns errno == ENOENT. It is treated as
776 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
778 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
779 both client and server. Code by Morten Bøgeskov.
783 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
784 that they can be used directly from Visual Basic. You must recompile
785 your windows APP if you're using ZOOM.
787 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
788 Commands "lang" and "charset" sets language and character set respectively.
789 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
790 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
792 Attributes from multiple CCL fields may be OR'ed rather than merged
793 using directive "@field or". Fields are still merged by default -
794 equivalent to "@field merge".
796 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
799 Fixed bug in zget for parameter ExtendedServicesResponse.
805 Added PQF feature: '@attr type=value' may be written as '@type=value'.
807 Client displays USR.1:SearchResult-1 (hits per term).
809 Additional Search Info for search in Generic Frontend Server.
811 Fixed CCL parsing of "field=s".
813 WIN32 installer - using the excellent NSIS software from nullsoft.
815 Fixed CCL parsing of "field = - <number>".
817 Added function yaz_marc_decode that decodes MARC for line mode
818 display or XML (similar to that used by JZKit).
820 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
821 Z39.50. But ISO/ILL was, however.
823 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
824 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
826 http://lcweb.loc.gov/z3950/agency/amend/am2.html
827 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
831 New YAZ client features: Command completion and new commands:
832 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
833 Code provided by Jacob Poulsen.
835 New call oid_trav, that visits all registered OIDs via callback.
837 Function ZOOM_record_get now returns const char pointer rather than
838 void pointer. It saves a lot of type casts.
840 For YAZ client, command "auth" now allows you to set authentication
841 in IdPass style. It is enabled when three tokens are given - order
842 is user, group and password.
844 Fix memory leaks in MARC record handling for ZOOM.
846 New option for YAZ client, -k <kilobytes> that sets
847 maximum record size. Similar to -k option for generic frontend
848 server and yaz-ztest.
850 More fixes for scan. Non-zero stepSize handled. OID's fixes.
852 Prefix query parser reports "fail" when bad attribute set is given.
854 Fix in MARC decoder. Proximity logging. Fix for attribute set
855 in scan handler for server. Patches by Shigeru Ishida.
857 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
860 Configure option --with-openssl=<dir> now works when a directory is
861 specified. Patch provided by Morten Bøgeskov.
863 New option for YAZ client, -u <auth>, that sets authentication.
865 ZOOM fix: error information was sometimes "missing", since error
866 was cleared/reset too when it shouldn't.
868 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
872 Scan for ZOOM API. New object ZOOM_scanset. New functions
873 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
874 ZOOM_scanset_destroy.
876 New ZOOM function, ZOOM_connection_last_event, that returns type
877 of last event (such as "receive data", "send data", "apdu received",
880 New ZOOM option, schema, that specifies schema for retrieval.
882 New CCL feature. Qualifiers can be aliases for one or more
883 other qualifiers (if more than one is given, OR is used).
885 ZOOM uses named result sets if target supports it.
887 Two new YAZ client commands: . (dot, which sources a script of YAZ
888 client commands), and ! (to execute shell command.). Implemented
891 Working on Debian packages.
895 YAZ client enables named result sets only if target supports it.
897 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
899 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
900 with key="host" to get same result.
902 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
903 Function Z3950_resultset_record(s) returns references to records
904 "owned" by resultset. To become owner use Z3950_record_clone.
906 Function z_ext_record handles Extended Services. Thanks to
911 CCL Parser fix: ignore token comma when dealing with and-lists.
913 Documentation updates for COMSTACK.
915 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
916 Changed prototype Z3950_records. For some functions, int parameters
917 were changed to size_t.
919 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
922 New MARC decode/display function, marc_display_exl, which properly rejects
923 non-ISO2709 records. YAZ client uses it.
927 Fix bug: local attribute set wasn't set correctly in PQF strings.
931 * Old Z39.50 codecs no longer supported.
933 Added ZOOM C binding. See http://zoom.z3950.org/
935 Renamed states for COMSTACKs to avoid confusion with events.
937 Implemented cs_look and proper cs_rcvconnect.
939 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
941 Configure detects POSIX threads on OpenBSD.
943 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
944 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
946 When error is returned from present handler, non-surrogate diagnostic
947 is returned in present response (and fetch handler is no longer called).
949 * Minor adjustments to pquery parser (PQF). Token characters may be
950 escaped by using backslash (C-style).
952 PQF parser allows string attribute values to be specified. For @attr,
953 non-numeric characters after the equal-sign are treated as strings
954 (e.g. @attr 9=title).
956 CCL trunction character may be defined (@truncation in file)
958 * function zget_ExtendedServicesRequest sets waitAction to
959 waitIfPossible (was wait).
961 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
964 CCL operator names may be set in field definition files (CCL_bibset).
965 See ccl/bib1 for an example.
967 Fixes in ASN.1 compiler for C++ compatibility.
969 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
970 and "op_or" to avoid conflict with C++.
972 Fixed problem with GNU readline detection on Redhat 7.0.
974 Added step-size for Scan backend handler.
976 Fixed bug that made the frontend server crash when no attribute
977 set was specified for scan.
979 Front-end server automatically switches to original working directory
980 when installed as an NT service. Previously -w had to be specified to
983 Added extended attributes for retrieval module (data1), so that data1
984 records carry d1_readXML/SGML attributes. d1_read also supports
985 null-data rules ( <tag/>)
987 On UNIX when POSIX threads are available, a separate library libyazthread
988 is created. Programmers should link with that library and the yaz library
989 when using threads. The reason for the split was that some applications
990 on Linux, such as Apache, doesn't work well when using shared objects that
993 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
994 (or any frontend server) in SSL mode by specifying ssl: followed by
995 address. Only tested on UNIX.
997 Added feature for CCL module. Virtual structure s=al or s=ol generates
998 and-list and or-list respectively instead of phrase search.
1002 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1003 log_mask_str. This was done to avoid name conflicts with other libraries
1004 (such as other PHP extensions).
1006 Added raw OID member for preferred record syntax (request_format_raw)
1007 and returned record syntax (output_format_raw) for backend fetch method.
1009 Config file yaz-config now accepts options so that it returns specific
1010 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1012 Shared library support for UNIX using GNU libtool.
1014 * Modified backend interface. Request/Response struct's replaced by
1015 one read/write C struct. For example bend_fetchrequest and
1016 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1017 Every handler - even search has to be registered in bend_init
1018 handler. This means that the YAZ library no longer refers to
1019 external functions and it makes it possible to make the whole
1020 thing a single DLL/SO.
1022 Added Segment handler for backend server.
1024 Added Zmbol/Zebra administrative functions to YAZ client.
1026 Threaded frontend server on UNIX (when POSIX Threads are available).
1027 Starting the server with option -T enables multi-threading.
1031 Added configure option --enable-comp/disable-comp to control use
1032 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1033 located in sub directory asn.
1035 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1036 in ${exec_prefix}/bin along with the other programs yaz-client and
1039 GNU automake used to maintain makefiles.
1041 Added several OID's.
1043 Changed retrieval module so that we can load records with no abstract
1044 syntax defined. Tagpaths in these records are fully composed of string
1047 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1051 On UNIX, the generated makefile now supports a proper 'make install'.
1052 The prefix can be set via GNU configure to set the install location
1053 (default is /usr/local).
1055 * YAZ programs client and ztest were renamed to yaz-client and
1056 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1057 locations, such as /usr/bin,/usr/local/bin,etc.
1059 * YAZ Header files were moved from include to include/yaz. YAZ Header
1060 files are referred to as include <yaz/log.h> rather than <log.h>.
1061 The YAZ include path (-I ..) is therefore the same as before. Programmers
1062 should update their #include statements or use -Ipath/include/yaz
1063 instead. The main motivation for doing this change is that YAZ header files
1064 can be installed in "standard" locations /usr/include,/usr/local/include
1065 without introducing conflicts, since ALL YAZ header files are stored
1066 in subdirectory yaz (under /usr/include for example).
1068 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1069 rather than project/workspace files. We switched because project files
1070 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1073 Changed name of logging function, logf, to yaz_log, to prevent name
1074 clash with some math-log functions. The YAZ header log.h defines logf
1075 to yaz_log (#define) so there should be no incompatibilities by this
1078 Added bend_start/bend_stop handlers for server. These handler are
1079 called on start/stop of server. For windows they are called whenever
1080 a service is started/stopped.
1082 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1083 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1084 in util/yc.tcl. The auto-generated C code structures are, in a few
1085 cases, incompatible with the old decoders. There are differences in the
1086 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1087 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1088 The preprocessor variable ASN_COMPILED is defined when the compiled
1089 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1090 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1091 wish to use the old encoders/decoders you can specify --disable-yc
1094 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1095 version so that it supports both new - and old version of DB Update
1097 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1098 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1099 change. The name parameter can be set to 0 in which no name is specified
1100 for the construction. The macros odr_implicit and odr_explicit sets name
1101 parameter to zero for the construction involved. New macros
1102 odr_implicit_tag and odr_explicit_tag are similar to the others,
1103 except that a name parameter is added. For programmers' that don't use
1104 ODR they probably only need to change the call to z_APDU and z_External.
1106 Added access control facility by interfacing the TCP wrapper library.
1107 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1108 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1109 name of the daemon and enables the access control as specified in
1110 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1112 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1113 den Dool <H.M.vdnDool@kub.nl>.
1115 Added reference ID parameter to most functions in server API - refer
1116 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1118 Changed name of ccl library to libccl.a (was ccl.a).
1120 Fixed bug in decoder for Explain (Category TargetInfo).
1122 Added support for GNU readline in client. Thanks to Jacob Poulsen
1123 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1125 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1126 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1127 IMPLEMENTATION! This change was made to the development version before
1128 the ZIG decided to retract the amendment. If any users MUST be
1129 compatible with the original Update definition, PLEASE CONTACT US, and
1130 we will include a separate definition corresponding to the old Update
1131 ES. Note that because of the change to the ASN.1 of the
1132 TaskPackageRecordStructure we cannot define a single structure that
1133 will support both versions.
1135 * Added const modifier to buffer parameter for some ODR/BER encoding
1136 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1137 completeWAIS, odr_dumpBER.
1139 Fixed bug in client.c which caused a crash when a scanResponse didn't
1140 contain positionOfTerm.
1142 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1143 * will cause an error in a client if a non-YAZ target sends both a
1144 * list of Scan entries and non-surrogate diagnostics.
1146 Retrieval module enhancements. Tag sets may be typed in the reference
1147 to it. From the .abs-file the "tagset" directive takes a third optional
1148 integer type for the tag set referenced. From a .tag-file the "include"
1149 directive takes a third optional type as well. The old "type" directive
1150 in the tag set itself is still recognized but acts as the default type
1153 Backend interface change. Individual Scan terms returned from bend_scan
1154 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1155 in include/backend.h.
1157 Retrieval module enhancements. Multiple tag sets and attribute sets may
1158 be specified in abstract syntax specs. Revised the error/warning for
1159 logging messages reported by the retrieval module when reading the
1162 Object Identifier system (oid_..) changed. The API is backwards
1163 compatible but the oid-routines now allocates new OID's when needed.
1164 Raw OID's may be specified in oid_getvalbyname.
1166 YAZ now uses GNU configure to generate Makefile(s).
1168 * Minor changes in some of the member names of DeleteResultSetRequest and
1169 DeleteResultSetResponse. See include/proto.h.
1171 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1172 and added member 'languages' in TargetInfo (which was missing).
1174 Changed the way attribute sets are handled in the retrieval
1175 module. These are now cached, just like the abstract syntaxes
1178 Changed YAZ so that it links with compiled ASN.1.
1180 Added Explain-schema definitions and mapping routines. The following
1181 Explain categories have been implemented: AttributeDetails,
1182 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1184 Fixed minor bug in Windows version of Server Library.
1186 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1188 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1190 Added EXTERNAL: UNIverse Resource Report (non-standard).
1192 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1193 ENUMERATED and SET OF.
1195 * Added 'const' to some of the char pointer arguments for the
1196 functions, data1_read_node, data1_getelementbytagname,
1197 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1200 Fixed bug in data1_insert_taggeddata - the last_child member of
1201 parent wasn't initialised.
1203 * Changed data1_read_record and data1_read_node so that the supplied
1204 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1205 doesn't refer to any parts of the "SGML"-buffer.
1207 Fixed bug in server library (Windows version of statserv_remove).
1209 * Changed code so that it compiles as C++. The type definition
1210 of Odr_fun which is a member of Odr_arm was changed. The result is,
1211 that an explicit typecast is needed for the fun pointer when
1212 using Odr_arm - as in:
1213 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1215 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1217 Implemented the new structured date and time definition as approved
1218 by the ZIG. Added schemaId element to the specificTag in Espec-1
1219 (also approved at the last ZIG). Thanks to RVDM.
1221 Added some Object identifiers (RVDM).
1223 Changed the Update Extended Service (RVDM).
1225 Added command "refid" to client which specifies referenceId for
1226 the following requests.
1228 Implemented extended service handling for server. See ztest.c
1229 for an example as well as backend.h. New handlers are registerd
1230 in the Init handler.
1232 * Changed interface for sort in server.
1234 Added new members to statserv_options_block. It allows a server
1235 to read options from another source than just the command line. Thanks
1236 to Charles Woodfield.
1238 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1239 renamed to zboolean. Some C++ compilers complained about the name.
1241 Minor changes to gils.abs. Added index 's' (sort) on title
1242 and date/time-last-modified.
1244 --- 1.4pl2 1998/1/30
1246 Fixed bug in server library regarding inetd mode (-i). This bug
1247 was introduced by release 1.4.
1249 --- 1.4pl1 1998/1/29
1251 Added sort facility in client and backend server interface.
1253 Fixed problem with dependencies in Makefile(s).
1255 Fixed bugs for encoders/decoders of extended services and
1258 Implemented sub-tree feature for schemas. Sub-trees are
1259 referenced in *.abs-files. See explain.abs for an example
1260 of the use of this feature.
1262 Modified bib1.att; local attributes for ANY didn't include
1263 ANY itself (only affects use of the retrieval module).
1265 Fixed bug in plain SGML reader in function data1_read_node:
1266 tags with prefix "var" was incorrectly interpreted as variants.
1268 Added feature "sub-schemas" to enable references to - and definitions
1269 of - group of elements.
1271 * Removed member parent from type data1_element (in data1.h).
1273 Implemented function odr_nullval() that returns the value of
1276 * Removed member num_children from data1_node (in data1.h).
1278 Made NT service interface part of the server library. The
1279 function statserv_main uses the NT service when required and
1280 calls the statserv_start / statserv_close routines.
1282 Routine zget_SearchRequest and zget_PresentRequest fills
1283 resultSetName/Id member with "default" instead of "Default".
1285 Fixed memory leak in server. Request queue member wasn't freed.
1287 Fixed nmem_exit so that memory is freed.
1291 Revised the CCL parser utility to be thread safe.
1293 Added function, oid_ent_to_oid, to replace the function
1294 oid_getoidbyent, which is not thread safe.
1296 * Added nmem_init and nmem_exit to initialize and release
1297 NMEM resources. Function nmem_init should be called once in the
1298 initial thread before NMEM/ODR is used. statserv.c and client.c
1299 have been changed accordingly. The change was necessary to make
1300 NMEM thread safe. The NMEM memory pool is shared amongst threads
1301 in a process. Unix-based applications will still work fine without
1304 Added NT Services interface for the the Z39.50 (statserv) Server.
1305 Refer to the ztest.c source on the usage.
1307 Windows 95/NT port using MSVC5.0. Project files are included in the
1310 * Defined new 'global' handle for the retrieval (data1) system. The
1311 new handled, data1_handle, describes the state of the data1 system.
1312 This handle is passed as first argument to virtually all
1313 data1 related routines. The functions data1_create and data1_destroy
1314 creates and destroys a data1 handle respectively.
1316 Added ODR encode stream member to all backend request structures
1317 init, search, scan etc. This stream should be used to allocate all
1318 memory used for the response when thread safe operation is needed.
1320 Changed the comstack utility, cs_addstr, to be thread safe. The
1321 returned hostname string returned by the function is now part the
1324 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1325 function. The cs_straddr takes a COMSTACK handle as argument, so this
1326 function must be used after cs_create and before bind/connect.
1327 This function is thread safe.
1329 Moved test server to 'ztest' directory - generic server code still
1330 in 'server' directory.
1332 Made prefix query (pquery.c) utility thread safe.
1334 Added new function modifier YAZ_EXPORT to 'export' public DLL
1335 functions when using windows (see include/yconfig.h).
1337 Added definitions to the OID database (util/oid.c) (RVDM).
1339 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1341 Added call to ccl_rpn_delete in client program.
1343 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1344 release of RPN structure.
1346 Added support for C++, headers uses extern "C" for public definitions.
1347 With input from RVDM.
1349 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1350 Thanks to Ronald van der Meer (RVDM).
1352 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1354 Added support for private extensions to the OID database
1355 (oid_setprivateoids()). Thanks to RVDM.
1357 Added optional, physical ANY (key replication)
1359 Fixed null-reference problem in GRS-1 output filter.
1361 Proximity operator added to Prefix Query Format (PQF).
1363 In test client command "base" accepts multiple databases.
1365 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1369 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1371 Smallish bug-fixes in the new encoders/decoders (explain).
1373 Bug fixed in DeleteRequest.
1375 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1377 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1379 Added SOIF syntax (using private OID for now) to retrieval module and client.
1381 Added Update extended service.
1383 Added SearchResult-1 additional info structure.
1385 Added optional CCL (ISO8777) interpreter as separate module. Available
1388 --- 1.2 1996/6/10 (1st anniversary release)
1390 Added Summary record syntax. Lightly tested.
1392 Added OPAC record syntax. Untested.
1394 Added ResourceReport service encoders/decoders. Untested.
1396 Fixed bug in z_Unit - wrong tagging on unitSystem.
1398 Fixed bug in the DiagRecs decoder.
1400 Added options for max PDU size and session timeout to frontend-server.
1402 Added documentation of query-language parsers and other supporting utilities.
1404 [frontend-server] Added Attribute set to the bend_scanrequest API.
1406 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1407 surrogate diagnostics were generated.
1409 [retrieval] Allow multiple local values for attribute.
1411 [retrieval] Allow multiple attributes per element in .abs files. index type.
1413 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1415 --- 1.1pl2 1996/4/10
1417 Minor changes, mostly specific to Zebra's requirements (retrieval)
1421 Repaired bug in frontend server when running multiple listening
1422 endpoints in dynamic mode.
1424 z_External() now won't break if a known, ASN.1 value comes encapsulated
1425 in an octet-string. The value will pass through unmodified in an Odr_oct.
1427 Added a bit of code to the demo client to decode & display
1428 ASN.1-structured records represented in the octet-aligned branch of
1429 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1431 Added z_ext_getentbyref() to the ASN module. Doc updated.
1433 * Completed the SCAN definition in the ASN module. This may break SCAN
1434 code based on older YAZ-versions at compile-time. The fix is easy -
1437 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1438 under the SCAN definition. Remember to initialize this, server-people.
1440 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1441 that this does not extend to ODR and ASN.
1443 Comstack allows insertion of established socket (primarily for
1444 inetd-operation of servers). Doc updated.
1446 Front-end server can now start from the inetd in TCP mode. Doc
1449 --- 1.0pl4 1996/1/24
1453 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1454 the rank and record number.
1456 Adjustments to the frontend server.
1458 Fixed diagnostic BER dumper. It ignored the file argument.
1462 Various changes to retrieval module.
1464 Changed the union discriminators of the protocol files from enums to
1465 ints paired with #defines.
1467 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1470 *Changed operator in the RPN structure to 'roperator', again to avoid a
1473 Fixed problems in Explain decoders/encoders.
1475 --- 1.0pl2 1995/12/6
1477 Memory bug in log module fixed.
1479 --- 1.0pl1 1995/12/5
1481 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1483 Bug in Explain DatabaseInfo module fixed.
1485 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1489 The shift to v1.0 signals that we now consider the *core* functionality
1490 of YAZ reasonably stable (the core being more or less equivalent to
1491 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1492 tested (Explain not at all - though that will happen soonish).
1494 Minor changes to code to support Windows port.
1496 Various minor changes after we're getting to use GRS-1 & co. more.
1498 Added Espec-1 format.
1500 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1501 of the protocol and it cannot be selected when encoding (maps into 'string'
1502 when decoding). Needed to talk to some servers.
1504 Demo client can request simple element set names.
1506 Added Diagnostic Format encoders/decoders.
1508 Added simple Close handling to frontend server (no hooks for resource
1509 reporting yet), and demonstration client.
1511 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1513 --- 1.0b3 1995/08/24
1515 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1516 handled incorrectly when records were requested in the searchResponse. This
1517 will only affect you if you use the frontend-server.
1519 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1520 Test-client will ask for and print GRS1. Ztest will return dummy records
1523 Added Explain encoders/decoders to the service-level API. Untested.
1525 Added Extended Services: Item Order encoders and decoders to the Service-
1526 level API. Untested. We could use a recent copy of the pertinent bits
1527 of the ILL protocol to add those bits.
1529 Added diagnostic format 1 encoders/decoders to the service-level API.
1532 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1533 odr_cons.c, which causes a more correct output.
1535 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1536 was always set to 0 when no records were requested in the searchRequest.
1538 * Added better external-handling. This shouldn't harm old code that
1539 *encodes* externals. It can break code that looks for a
1540 'single-ASN1-type' representation, since those types that are known
1541 are now decoded immediately. Look at the SUTRS sample code in
1542 seshigh.c and client.c. Documentation updated.
1544 Handling of structured records in bend_fetchresponse. Length -1 marks
1545 structured record, type is deduced from format field.
1547 --- 1.0b2 1995/06/27
1548 Fairly quick maintenance release to add SUTRS support.
1550 Fixed handling of SUTRS records in the demonstration client.
1552 * Added format field to the bend_fetchrequest and bend_fetchresponce
1553 structures of the backend API (frontend server). When the record is
1554 returned, the value of the format field is mapped to an OID. The
1555 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1556 of the record. The special value VAL_NONE in the bend_request means
1557 that no specific format was requested by the client. Documentation
1558 updated accordingly. Test server (ztest) will return a fixed dummy
1559 SUTRS record if your client requests SUTRS.
1561 Documentation updated accordingly.
1563 You can now set external libraries and RANLIB support in the top-level
1567 First public release.
