1 Added option -m to GFS to control formatting of timestamps in log file.
3 Added 'exit' as synonym for 'quit' in yaz-client
5 Possible compatibility problems with earlier versions marked with '*'.
7 Added support for specifying SRW resultSetId + resultSetIdleTime in a
8 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
9 for the new members. Patch by Ko van der Sloot.
11 Added support for SRU POST. It is supported for content-type
12 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
14 Do not build the separate Multi-threaded (MT) library libyazthread.la.
15 Instead make the library libyaz.la multi-threaded. Threading as a whole
16 can still be disabled by configure option --disable-threads. Previosly,
17 with older GLIBCs there were problems with MT libs under Apache. This
18 has now been fixed a long time ago.
20 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
23 CQL module modified to be case insensitive for relations/indexes/operations.
25 Fixed bug in CQL transform code: incorrect value relationModifieder
28 Added 'show all' command for yaz-client which retrieves all results
31 Added new yaz-client, xmles, which takes a (private) OID and
32 a document to be sent as an extended service request.
34 Describe new yaz-client commands wait_response and set_auto_wait.
36 Increase TCP/IP listener backlog from 3 (which I am guessing was
37 copied from the SunOS manual entry way back when) so SOMAXCONN, so
38 that the socket will queue as many incoming connections as it's able
39 to handle ongoing connections. In other words, it will never now
40 refuse a connection that it would be able to handle merely because
41 it's not got around to accepting() enough of the pending connections
42 yet. This is the behaviour anyway under Linux, where the listen()
43 argument is ignored; but not under BSD and on systems such as
44 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
45 YAZ-based servers should now be uniform across operating systems in
48 yaz-marcdump uses 64-bit file access on some systems. This is enabled
49 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
50 This allows yaz-marcdump to read large MARC batches (>2 GB).
52 Modified all YAZ source files - except the source which is auto-generated
53 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
58 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
59 MARC output rather than returning "new" buffer.
61 yaz-client warns about unknown init options.
63 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
67 Added support for SRW sort in Generic Frontend Server. Patch
68 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
69 sortKeys - or NULL if none is provided.
71 Fixed bug #307: It was impossible to specify indefinite/no timeout
72 for ZOOM_event. Special timeout value -1 now means indefinite timeout
75 Added support for multiple languages and charsets to be specified in
76 ZOOM. Each charset/language is separated by a blank. If negotiation is
77 in effect in init-response, Option
78 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
79 Code based on patch by Vasiliy Osadchuk.
81 Fixed bug #306: infinite recursion that occurred when calling
82 yaz_log_level_init as the first call (before other log level or
85 Fixed bug in scan handling in front end server: if preferred-Position-In-
86 Response was non-present, a NULL pointer referece was performed.
90 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
91 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
92 now defined for all those error codes. So instead of putting 109 in
93 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
94 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
96 Modified the yaz-marcdump utility to skip garbage bytes between MARC
99 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
101 Program yaz-client now exits and produces an error message if multiple
102 Z39.50 servers are specified on the command line (none or one allowed
105 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
110 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
112 Fixed bug #272: Preserve spacing for CCL terms.
116 Added support for virtual hosts and multiple backend servers for
117 the YAZ frontend server. The configution is XML based and
118 support specificition of CQL to RPN mappings and explain information.
119 See section "Virtual Hosts" in the YAZ manual.
121 Extended OPAC display utility. OPAC display utility renders
122 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
123 to supplement yaz_marc_decode_wrbuf.
125 Fixed a bug in MARC decoder that could caused it to crash for some
126 invalid MARC records. More diagnostics and warnings where added in
127 XML output (warnings, etc are stored in comments).
129 --- 2.0.34 2005/02/08
131 Fixes for UNIX domain sockets. Bug #261.
133 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
135 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
136 Added yaz_marc_subfield_str which defines subfield lead string which is
137 used in YAZ_MARC_LINE format. Default string is blank+$. Added
138 yaz_marc_endline_str which defines end of fields string used in
139 YAZ_MARC_LINE format. Default string is newline.
141 Experimental support for MarcXChange. This format can be produced
142 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
143 http://www.bs.dk/standards/MarcXchange.xsd
145 Added yaz-client commands scansize that sets maximum number of
146 entries to be returned by scan.
148 --- 2.0.32 2005/01/11
150 Added support for SRW scan in yaz-client and Generic Frontend Server.
152 * Added whereInList member to SRW Scan Term.
154 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
156 Fixed NMEM system to return aligned blocks on the smallest boundaries
157 that are suitably aligned for all possible types on the particular
158 architecture YAZ is being built for.
160 --- 2.0.30 2005/01/04
162 Fixed numerious warnings that was issued with newer versions of GCC.
164 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
165 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
168 Make YAZ Generic Frontend Server slightly faster.
170 Enhance (and reduce) logging for Generic Frontend Server.
172 Revert YAZ log system so that it flushes every write operation
173 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
175 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
176 instead of LOG_, due to name clash with syslog(3). LOG_ are still
177 present. New applications should define YAZ_USE_NEW_LOG=1 - this
178 will effectively disable old definitions.
180 --- 2.0.28 2004/11/09
182 Added yaz_log_time_format which specifies log format using
185 Added yaz_log_module_level which returns mask for a module. Value
186 is non-zero mask a if module is enabled; zero if disabled.
188 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
189 in include/yaz/cql.h.
191 Fixed bug #176: Dont throw diagnostics on empty SRU args.
193 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
195 Fixed bug #172: RPM builds does not enable SSL.
197 Doxyfile.in part of dist. Doxyfile generated by configure.
199 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
200 are given and the corresponding component does not exist.
202 Extend CCL documentation in YAZ reference. Describe r=r.
204 --- 2.0.26 2004/10/01
206 Fixed MARC->MARCXML conversion to properly deal with
207 fields, subfields, indicators having non-ASCII characters.
209 Fixed MARC->MARCXML conversion so that ASCII control characters
210 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
213 Added YAZ GFS support for conversion from Z39.50 surrogate
214 diagnostics to SRW surrogate diagnostics.
216 Bug fix: YAZ GFS did not return schema in explainResponse.
218 --- 2.0.25 2004/09/30
220 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
221 now converts recordSchema to elementSetName as well as schema URI.
223 Fixed bug in COMSTACK that prevented HTTP request packages from being
226 --- 2.0.24 2004/09/29
228 Added CCL facility r=r "range" which is similar to r=o "ordered" but
229 does not require white-space before and after the dash in a range, e.g.
230 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
233 Fixed a few AC_TRY_LINK configure tests that did not operate properly
234 due to new GCC removing "redundant" code.
236 Added yaz-client commands scanpos and scanstep that sets preferred
237 position and step-size for scan.
239 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
241 Added CCL utility ccl_qual_buf which parses one or more CCL
242 spec lines in a buffer.
244 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
245 of name and value - ignoring empty lines and comments.
247 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
249 Added odr_get_element_path which returns current element path for an
250 ODR handle. This utility is useful in error handling or user-defined
253 Added ODR_PRINT utility odr_set_stream which is is a more generic
254 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
255 to a write function and pointer to close function. The close function - if
256 non-NULL - will be called during odr_destroy.
258 Fixed bug in CCL parser where truncation char was not removed from
259 right side when truncation=both was in effect.
261 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
264 --- 2.0.23 2004/08/11
266 Fix buffer overrun in CQL parser when dealing with proximity (%).
268 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
269 to UTF-8/UCS conversion is now only based on codetables.xml.
271 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
273 --- 2.0.22 2004/08/06
275 Add support for more "commit changes" in ZOOM (uses Extended Services).
277 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
280 Yet another small fix for configure of SSL.
282 --- 2.0.21 2004/05/14
284 Fix SSL libs for configure when --with-openssl=DIR is given.
286 --- 2.0.20 2004/05/10
288 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
290 SSL comstack now uses yaz.pem certificate file on server side
291 by default. Certificate filename can be configured by calling
292 comstack function cs_set_ssl_certificate_file before cs_bind is used.
294 Fix bug regarding multiple calls to ZOOM_connection_connect.
296 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
298 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
299 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
301 ZOOM now allows inspection of X509 peer certificate for verification.
302 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
304 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
305 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
306 as "modular" but it simplifies things.
308 Added cs_get_peer_certificate to that returns peer X509 PEM.
310 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
311 NULL if SSL is unavailable.
313 Documentation about MARC decoding tools.
315 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
317 --- 2.0.19 2004/03/30
319 Rename CHANGELOG to NEWS to follow GNU style packing.
321 Fix bug with missing initialization of member in init_diagnostics.
322 This bug affects threaded version of GFS server.
324 --- 2.0.18 2004/03/20
326 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
329 Ensure zlib.dll is packed with Windows install.
331 --- 2.0.17 2004/03/17
333 Fix encoding of xsd:string to use text instead of CDATA.
335 Fix endless loop in CQL parser with unbalanced ".
337 Use a more compact way to store MARC-8 conversion tables.
339 --- 2.0.16 2004/03/16 Debian only
341 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
344 Update CQL parser to use new CQL 1.1 modifiers for booleans and
349 --- 2.0.15 2004/03/01
351 Another fix for decoding of XML packed records.
353 --- 2.0.14 2004/02/25
355 Fixes for Chunked encoding. White space not ignored after length spec.
357 Update NS and use default NS for SRW diagnostic elements.
359 --- 2.0.13 2004/02/23
361 Implement ZOOM_resultset_cache_reset which resets record cache.
363 Implement ZOOM_resultset_sort which sorts a result set.
365 Implement chunked HTTP transfer.
367 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
369 --- 2.0.12 2004/02/16
371 Added member 'schema' to bend_explain_rr structure so that backend
372 can specify explain record identifier. Defaults to Zeerex 2.0.
374 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
376 --- 2.0.11 2004/02/16
378 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
381 Added init command for yaz-client which sends "extra" init request.
383 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
384 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
386 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
388 Make ZOOM error code for "invalid query".
390 Fixed compilation for SSL which wasn't properly enabled for all platforms.
392 --- 2.0.10 2004/02/05
394 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
397 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
399 Added option -p <file> to make Generic Frontend Server to write PID file.
401 Added option -D to put Generic Frontend Server in background on its own.
403 Make ZOOM C recognize option "password". If unset, "pass" is used
404 (for backwards compatibility).
406 Fixed a bug in Generic Frontend Server that could make it crash if a
407 client sets characterSetNegotation bit, but didn't pass negotiation stuff
410 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
411 Must be issued before open, in order to be in effect.
413 --- 2.0.9-6 2004/01/12 Debian/Windows
415 Make the SRU server more picky WRT unknown params, etc.
417 Bug fix: ZOOM scan response didn't return displayTerm - when present.
419 New YAZ client command, options, that sets Z39.50 options.
421 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
422 options from a string of tokens (one token for each option bit).
424 Update SRW diagnostic code messages.
426 --- 2.0.9-5 2004/01/07 Debian/Windows
428 Handle user defined stylesheet for SRW/SRU.
430 --- 2.0.9-4 2004/01/06 Debian/Windows
432 Fix bug in decoding of Content-Length.
434 --- 2.0.9-3 2004/01/06 Debian/Windows
436 Fix a bug with decoding of XML packed records.
438 --- 2.0.9-2 2004/01/05 Debian only
440 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
442 Fix bug in SRW/SRU diagnostics decoding.
446 Fixed bug in Generic Frontend Server which could drop records exceeding
447 preferred message size. Reported and fixed by Irina Dijour.
449 Fixed calculation of package size for structured records in Generic
450 Frontend Server. Reported and fixed by Irina Dijour.
452 Fixed namespace for SRW/SRU diagnostics.
454 Fixed SEGV in yaz-client that occured for HTTP connection errors.
458 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
459 this version is incompatible with version 1.0 and older YAZ SRW/SRU
462 CQL changes to reflect recent changes to the specification:
463 * Documentation talks about context sets instead of index sets.
464 * Documentation talks about indexes instead of qualifiers.
465 * The CQL-to-PQF transformer's configuration file now uses
466 "index.set.name = <attributes>" instead of the old form
467 "qualifier.set.name = <attributes>". (Both forms are still
468 understood but the latter is deprecated.)
469 * CQL terms with no explicit index specified are now interpreted as
470 cql.serverChoice instead of srw.serverChoice (which of course
471 behaves exactly the same.)
475 MARC conversion can now generate ISO2709 output in another
476 character set. yaz-marcdump uses this facility if you invoke it
479 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
480 functions from there can be used from C++.
484 Frontend server now transfers memory from decoded packages to stream
487 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
488 references to show up.
490 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
491 the ZOOM Abstract API. The older names for the same options are still
492 also supported for the benefit of old applications.
494 ZOOM-C supports "implementationId" and "implementationVersion" options
495 to go along with "implementationName". These allow the user code to
496 specify identification strings to be sent to servers.
497 Add OID for the new ExtLite attribute set.
499 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
500 as requested/supplid by Ere Maijala <ere@atp.fi>
502 For generic frontend server, reverse the order of
503 "toolkit-supplied / application-supplied" strings sent as implementationId,
504 Name and Version. Also, remove the spaces around the slash. This brings
505 the GFS in line with the behaviour of ZOOM-C on the client side.
507 Add function ZOOM_scanset_display_term.
509 yaz-client shows scan displayTerm if present.
511 Utility yaz-iconv is now installed by default along with the man page
514 Extend configure check for OpenSSL to use pkg-config where available (such
517 Incorporate patch by Morten Bogeskov which allows a Unix file socket
518 server to specify uid/gid/mask for socket using the format
519 unix:[user=uid,][group=gid,][umask=mask,]file=path
520 If file= is omitted the existing format is assumed, e.g.
522 in which case the mask is 0666 (rw for everybody).
524 Major restructure of YAZ source. All source in libyaz is in src directory.
525 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
526 util (utility programs such as ASN.1 compiler, yaz-marcdump).
528 Added man page for utility yaz-marcdump (used to be called marcdump).
529 yaz-marcdump is installed by 'make install'.
531 Fixed a memory leak in Generic Frontend Server that occurred when decoding
532 of incoming package failed.
534 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
536 Change prototype of odr_perror: add const to message string.
538 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
540 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
541 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
542 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
543 DNS lookup. There should not be any compatibility problems with this
544 assuming that blocking=1 or 0 is used.
546 Fix bad reference in UNIX comstack in function cs_addrstr.
548 Fix for compilation on AIX.
550 The generic front-end server (server/seshigh.c) now supports returning
551 Init diagnostics to the client in User-information-field, in
552 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
557 Allow any CQL relation (not just all,any,exact,scr).
559 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
560 that features the same UI.
562 Implemented command update0 in YAZ client which is equivalent to
563 update but uses old of Ext Update ASN.1.
565 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
566 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
567 Previously no OID was used for this info.
569 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
570 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
571 returns 'malformed search term' otherwise.
573 SortResponse member resultCount now set to NULL in sort handler of
576 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
579 Add three new utility functions for translating OIDs between various
580 formats -- symbolic name such as "Usmarc", minus-1-terminated int
581 arrays and dotted strings such as "1.2.840.10003.9.5.1":
582 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
583 char *oid_to_dotstring(const int *oid, char *oidbuf);
584 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
586 Reverted modifications for ES Update definition for z_IU0Update
587 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
588 is back to YAZ 2.0.2.
590 String value attributes for CCL parser.
592 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
593 which their FirstSearch server returns in Init responses, sometimes
594 carrying useful diagnostic information when Init fails. This has the
595 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
596 "z39.50/oclcui.asn", where its definition is somewhat different from
597 what OCLC document on their web-site, as required to interoperate with
600 Support for anonymous authentication in yaz-client. Use the command
603 * Fix the OID of the Index Data-local "admin" Extended Service from
604 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
605 the 1000, which indicates a locally-defined OID, was a mistake.
609 Fix CCL directive @case handling so that it affects string match for
610 both CCL keywords and qualifiers.
612 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
613 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
614 Decoder has been updated with ASN.1 changes as listed in
615 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
616 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
617 z_IUUpdate, remains unchanged.
619 ZOOM_record_get may now return a record in a specific character set.
620 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
621 "from" is the character set of record as returned by target. "to" is
622 the character set to be returned. If omitted, "to" is UTF-8.
624 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
626 New ODR utility, odr_getelement, which returns name of element for
627 which encoding/decoding failed.
629 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
630 in cases where a required element was omitted.
632 Bug fix: some MARC8 sequences were not converted.
634 New ZOOM option "step" which specifies number of records to be
635 retrieved in one chunk. Used in conjunction with "start" and "count".
637 SRW support for yaz-client. Use scheme http: to use it, e.g.
640 yaz-client no longer does (un)intelligent character set conversions
641 by default. Can be enabled with charset and marc_charset commands.
643 xmalloc trace fix for 64-bit systems such as DEC alpha.
645 Solaris 2.6 compile fix.
647 New function, cql_strerror() translates SRW error codes, as returned
648 by cql_transform_error(), into human-readable English strings. Used
649 in yaz-client diagnostics when appropriate.
651 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
652 converts it into a type-1 query which is sent to the server. This
653 makes CQL available for use with all Z-servers, as opposed to the tiny
654 minority that can handle CQL queries themselves.
658 New Debian package layout similar to the Redhat Package layout.
660 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
661 and search result respectively.
665 Redhat package is now several packages: libyaz (runtime libraries),
666 libyaz-devel (development and documentation, and yaz (utility programs).
667 Package spec file by Morten Bøgeskov.
669 New member 'schema' in struct bend_fetch_rr which the name of requested
670 schema (SRW/SRU) for record (or NULL if none was given). The fetch
671 handler MAY set this to reflect the schema of the returned record.
673 New member 'display_term' in struct scan_entry. GFS now sets member entries
674 and allocates scan entries to be filled by user scan handler. In previous
675 version, entries member was allocated by the scan handler. That still works,
676 but the GFS will ignore member display_term - assuming it was NOT set by
677 the handler. The fact that the GFS now allocates the entries both allows
678 for new members and makes a scan handler easier to write.
680 Fix CQL lex buffer overflow.
682 SRW/SRU recordPacking. For SRW default recordPacking is string. For
683 SRU default recordPacking is string.
685 SRU protocol support for frontend server.
687 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
689 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
691 Added scan for the ZOOM shell (zoomsh).
695 * String Identifers for Schemas (Amendment 5).
696 http://lcweb.loc.gov/z3950/agency/amend/am5.html
697 Old definition for schema
698 Odr_oid *schema; /* OPT */
703 Z_InternationalString *uri;
704 #define Z_Schema_oid 1
705 #define Z_Schema_uri 2
708 * resultCount parameter to Sort Response (Amendment 1).
709 http://lcweb.loc.gov/z3950/agency/amend/am1.html
711 Support for SRW 1.0 over HTTP. This is an optional feature and
712 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
715 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
716 on the same port. SRW SearchRetrieveRequests are mapped
717 to bend_init,bend_search,bend_fetch,bend_close.
719 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
721 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
722 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
724 ZOOM connections are SRW based if schem http is used for hostname
725 in connect, e.g. z = ZOOM_connection_new("http://myserver");
726 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
728 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
729 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
730 distance=n, order=true/false, relation=le, prox unit=word. If
731 n is omitted, distance 1 is used.
733 Fixed problem with C compiler include path in wrong order.
735 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
736 on Solaris. Patch from Ko van der Sloot.
738 New MARC decode API. All new functions operate on a yaz_marc_t
739 handle. The most important new functions are: yaz_marc_create,
740 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
741 decode and destroy respectively. Decoder can produce formats
742 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
743 include/yaz/marcdisp.h.
745 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
746 to UTF-8, UCS-32, wchar_t or Latin-1.
748 * Prototypes for yaz_iconv_-functions moved to separate header
749 include/yaz/yaz-iconv.h.
751 Make a few private functions 'static' in unix.c. This prevents
752 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
754 For ZOOM connection, the options targetImplementation{Id,Name,Version}
755 are set when Init Response is received.
757 New function ZOOM_connection_error_x similar to ZOOM_connection_error
758 but returns diagnostic set as well.
760 New function yaz_strerror which is a portable wrapper for
761 strerror/strerror_r/GetLastMessage.
763 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
764 is returned for MARC. If type is "oai", then OAI MARC is returned.
766 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
771 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
773 Fix bad race conditions on SIGTERM and terminate gracefully in
776 Move retrieval (data1) module to Zebra since nobody seems to be
779 Add GRS-1 render for ZOOM using same format as yaz-client.
783 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
785 Fix broken ESpec handling in data1 module.
787 SGML reader parses comments and makes them part of the data1 tree.
789 Added several type casts so that YAZ compiles as C++ code.
791 ZOOM didn't handle PDU encoding failures properly.
793 Added more Bib-1 diagnostics (approved extensions).
795 GNU configure: better check for iconv.
797 More portable use of accept, getpeername. Check for socklen_t. Use
798 int/size_t if socklen_t is not defined.
802 PQF parser rejects bad queries - including those with extra
803 characters in them. PQF parser used to silently ignore that.
804 Cleaner API for PQF added, which allows you to get detailed
805 error information for bad queries (see yaz/pquery.h).
807 Fixed bug in ZOOM_record_get for type "database".
809 Implemented mini iconv library supporting conversions between
810 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
812 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
816 Fixed ZOOM C record cache so that preferredRecordSyntax and
817 elementSetName is used to check for already fetched records.
821 Added three members in bend_initrequest structure to facilitate
822 character set negotiation.
824 Fixed a bug in frontend server that could cause indefinite
825 loops under rare conditions.
827 Revised character set utilities (charneg.h) so that encoding
828 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
830 For PQF, directive @term <type> sets term type for Scan/Search.
831 Here <type> is general, string, numeric, null. The term type
832 is inherited - just like @attr.
834 New call odr_set_charset that sets character set conversion for
835 international-strings on a ODR stream. Prototype is:
836 int odr_set_charset(ODR o, const char *to, const char *from);
837 The InternationalString is still represented as C string in YAZ
838 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
839 won't). On the protocol level, you can use any encoding.
841 Support for UNIX sockets in ZOOM.
843 Solaris recv sometimes returns errno == ENOENT. It is treated as
844 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
846 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
847 both client and server. Code by Morten Bøgeskov.
851 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
852 that they can be used directly from Visual Basic. You must recompile
853 your windows APP if you're using ZOOM.
855 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
856 Commands "lang" and "charset" sets language and character set respectively.
857 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
858 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
860 Attributes from multiple CCL fields may be OR'ed rather than merged
861 using directive "@field or". Fields are still merged by default -
862 equivalent to "@field merge".
864 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
867 Fixed bug in zget for parameter ExtendedServicesResponse.
873 Added PQF feature: '@attr type=value' may be written as '@type=value'.
875 Client displays USR.1:SearchResult-1 (hits per term).
877 Additional Search Info for search in Generic Frontend Server.
879 Fixed CCL parsing of "field=s".
881 WIN32 installer - using the excellent NSIS software from nullsoft.
883 Fixed CCL parsing of "field = - <number>".
885 Added function yaz_marc_decode that decodes MARC for line mode
886 display or XML (similar to that used by JZKit).
888 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
889 Z39.50. But ISO/ILL was, however.
891 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
892 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
894 http://lcweb.loc.gov/z3950/agency/amend/am2.html
895 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
899 New YAZ client features: Command completion and new commands:
900 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
901 Code provided by Jacob Poulsen.
903 New call oid_trav, that visits all registered OIDs via callback.
905 Function ZOOM_record_get now returns const char pointer rather than
906 void pointer. It saves a lot of type casts.
908 For YAZ client, command "auth" now allows you to set authentication
909 in IdPass style. It is enabled when three tokens are given - order
910 is user, group and password.
912 Fix memory leaks in MARC record handling for ZOOM.
914 New option for YAZ client, -k <kilobytes> that sets
915 maximum record size. Similar to -k option for generic frontend
916 server and yaz-ztest.
918 More fixes for scan. Non-zero stepSize handled. OID's fixes.
920 Prefix query parser reports "fail" when bad attribute set is given.
922 Fix in MARC decoder. Proximity logging. Fix for attribute set
923 in scan handler for server. Patches by Shigeru Ishida.
925 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
928 Configure option --with-openssl=<dir> now works when a directory is
929 specified. Patch provided by Morten Bøgeskov.
931 New option for YAZ client, -u <auth>, that sets authentication.
933 ZOOM fix: error information was sometimes "missing", since error
934 was cleared/reset too when it shouldn't.
936 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
940 Scan for ZOOM API. New object ZOOM_scanset. New functions
941 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
942 ZOOM_scanset_destroy.
944 New ZOOM function, ZOOM_connection_last_event, that returns type
945 of last event (such as "receive data", "send data", "apdu received",
948 New ZOOM option, schema, that specifies schema for retrieval.
950 New CCL feature. Qualifiers can be aliases for one or more
951 other qualifiers (if more than one is given, OR is used).
953 ZOOM uses named result sets if target supports it.
955 Two new YAZ client commands: . (dot, which sources a script of YAZ
956 client commands), and ! (to execute shell command.). Implemented
959 Working on Debian packages.
963 YAZ client enables named result sets only if target supports it.
965 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
967 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
968 with key="host" to get same result.
970 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
971 Function Z3950_resultset_record(s) returns references to records
972 "owned" by resultset. To become owner use Z3950_record_clone.
974 Function z_ext_record handles Extended Services. Thanks to
979 CCL Parser fix: ignore token comma when dealing with and-lists.
981 Documentation updates for COMSTACK.
983 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
984 Changed prototype Z3950_records. For some functions, int parameters
985 were changed to size_t.
987 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
990 New MARC decode/display function, marc_display_exl, which properly rejects
991 non-ISO2709 records. YAZ client uses it.
995 Fix bug: local attribute set wasn't set correctly in PQF strings.
999 * Old Z39.50 codecs no longer supported.
1001 Added ZOOM C binding. See http://zoom.z3950.org/
1003 Renamed states for COMSTACKs to avoid confusion with events.
1005 Implemented cs_look and proper cs_rcvconnect.
1007 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1009 Configure detects POSIX threads on OpenBSD.
1011 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1012 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1014 When error is returned from present handler, non-surrogate diagnostic
1015 is returned in present response (and fetch handler is no longer called).
1017 * Minor adjustments to pquery parser (PQF). Token characters may be
1018 escaped by using backslash (C-style).
1020 PQF parser allows string attribute values to be specified. For @attr,
1021 non-numeric characters after the equal-sign are treated as strings
1022 (e.g. @attr 9=title).
1024 CCL trunction character may be defined (@truncation in file)
1026 * function zget_ExtendedServicesRequest sets waitAction to
1027 waitIfPossible (was wait).
1029 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1032 CCL operator names may be set in field definition files (CCL_bibset).
1033 See ccl/bib1 for an example.
1035 Fixes in ASN.1 compiler for C++ compatibility.
1037 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1038 and "op_or" to avoid conflict with C++.
1040 Fixed problem with GNU readline detection on Redhat 7.0.
1042 Added step-size for Scan backend handler.
1044 Fixed bug that made the frontend server crash when no attribute
1045 set was specified for scan.
1047 Front-end server automatically switches to original working directory
1048 when installed as an NT service. Previously -w had to be specified to
1051 Added extended attributes for retrieval module (data1), so that data1
1052 records carry d1_readXML/SGML attributes. d1_read also supports
1053 null-data rules ( <tag/>)
1055 On UNIX when POSIX threads are available, a separate library libyazthread
1056 is created. Programmers should link with that library and the yaz library
1057 when using threads. The reason for the split was that some applications
1058 on Linux, such as Apache, doesn't work well when using shared objects that
1061 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1062 (or any frontend server) in SSL mode by specifying ssl: followed by
1063 address. Only tested on UNIX.
1065 Added feature for CCL module. Virtual structure s=al or s=ol generates
1066 and-list and or-list respectively instead of phrase search.
1070 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1071 log_mask_str. This was done to avoid name conflicts with other libraries
1072 (such as other PHP extensions).
1074 Added raw OID member for preferred record syntax (request_format_raw)
1075 and returned record syntax (output_format_raw) for backend fetch method.
1077 Config file yaz-config now accepts options so that it returns specific
1078 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1080 Shared library support for UNIX using GNU libtool.
1082 * Modified backend interface. Request/Response struct's replaced by
1083 one read/write C struct. For example bend_fetchrequest and
1084 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1085 Every handler - even search has to be registered in bend_init
1086 handler. This means that the YAZ library no longer refers to
1087 external functions and it makes it possible to make the whole
1088 thing a single DLL/SO.
1090 Added Segment handler for backend server.
1092 Added Zmbol/Zebra administrative functions to YAZ client.
1094 Threaded frontend server on UNIX (when POSIX Threads are available).
1095 Starting the server with option -T enables multi-threading.
1099 Added configure option --enable-comp/disable-comp to control use
1100 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1101 located in sub directory asn.
1103 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1104 in ${exec_prefix}/bin along with the other programs yaz-client and
1107 GNU automake used to maintain makefiles.
1109 Added several OID's.
1111 Changed retrieval module so that we can load records with no abstract
1112 syntax defined. Tagpaths in these records are fully composed of string
1115 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1119 On UNIX, the generated makefile now supports a proper 'make install'.
1120 The prefix can be set via GNU configure to set the install location
1121 (default is /usr/local).
1123 * YAZ programs client and ztest were renamed to yaz-client and
1124 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1125 locations, such as /usr/bin,/usr/local/bin,etc.
1127 * YAZ Header files were moved from include to include/yaz. YAZ Header
1128 files are referred to as include <yaz/log.h> rather than <log.h>.
1129 The YAZ include path (-I ..) is therefore the same as before. Programmers
1130 should update their #include statements or use -Ipath/include/yaz
1131 instead. The main motivation for doing this change is that YAZ header files
1132 can be installed in "standard" locations /usr/include,/usr/local/include
1133 without introducing conflicts, since ALL YAZ header files are stored
1134 in subdirectory yaz (under /usr/include for example).
1136 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1137 rather than project/workspace files. We switched because project files
1138 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1141 Changed name of logging function, logf, to yaz_log, to prevent name
1142 clash with some math-log functions. The YAZ header log.h defines logf
1143 to yaz_log (#define) so there should be no incompatibilities by this
1146 Added bend_start/bend_stop handlers for server. These handler are
1147 called on start/stop of server. For windows they are called whenever
1148 a service is started/stopped.
1150 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1151 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1152 in util/yc.tcl. The auto-generated C code structures are, in a few
1153 cases, incompatible with the old decoders. There are differences in the
1154 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1155 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1156 The preprocessor variable ASN_COMPILED is defined when the compiled
1157 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1158 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1159 wish to use the old encoders/decoders you can specify --disable-yc
1162 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1163 version so that it supports both new - and old version of DB Update
1165 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1166 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1167 change. The name parameter can be set to 0 in which no name is specified
1168 for the construction. The macros odr_implicit and odr_explicit sets name
1169 parameter to zero for the construction involved. New macros
1170 odr_implicit_tag and odr_explicit_tag are similar to the others,
1171 except that a name parameter is added. For programmers' that don't use
1172 ODR they probably only need to change the call to z_APDU and z_External.
1174 Added access control facility by interfacing the TCP wrapper library.
1175 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1176 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1177 name of the daemon and enables the access control as specified in
1178 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1180 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1181 den Dool <H.M.vdnDool@kub.nl>.
1183 Added reference ID parameter to most functions in server API - refer
1184 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1186 Changed name of ccl library to libccl.a (was ccl.a).
1188 Fixed bug in decoder for Explain (Category TargetInfo).
1190 Added support for GNU readline in client. Thanks to Jacob Poulsen
1191 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1193 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1194 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1195 IMPLEMENTATION! This change was made to the development version before
1196 the ZIG decided to retract the amendment. If any users MUST be
1197 compatible with the original Update definition, PLEASE CONTACT US, and
1198 we will include a separate definition corresponding to the old Update
1199 ES. Note that because of the change to the ASN.1 of the
1200 TaskPackageRecordStructure we cannot define a single structure that
1201 will support both versions.
1203 * Added const modifier to buffer parameter for some ODR/BER encoding
1204 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1205 completeWAIS, odr_dumpBER.
1207 Fixed bug in client.c which caused a crash when a scanResponse didn't
1208 contain positionOfTerm.
1210 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1211 * will cause an error in a client if a non-YAZ target sends both a
1212 * list of Scan entries and non-surrogate diagnostics.
1214 Retrieval module enhancements. Tag sets may be typed in the reference
1215 to it. From the .abs-file the "tagset" directive takes a third optional
1216 integer type for the tag set referenced. From a .tag-file the "include"
1217 directive takes a third optional type as well. The old "type" directive
1218 in the tag set itself is still recognized but acts as the default type
1221 Backend interface change. Individual Scan terms returned from bend_scan
1222 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1223 in include/backend.h.
1225 Retrieval module enhancements. Multiple tag sets and attribute sets may
1226 be specified in abstract syntax specs. Revised the error/warning for
1227 logging messages reported by the retrieval module when reading the
1230 Object Identifier system (oid_..) changed. The API is backwards
1231 compatible but the oid-routines now allocates new OID's when needed.
1232 Raw OID's may be specified in oid_getvalbyname.
1234 YAZ now uses GNU configure to generate Makefile(s).
1236 * Minor changes in some of the member names of DeleteResultSetRequest and
1237 DeleteResultSetResponse. See include/proto.h.
1239 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1240 and added member 'languages' in TargetInfo (which was missing).
1242 Changed the way attribute sets are handled in the retrieval
1243 module. These are now cached, just like the abstract syntaxes
1246 Changed YAZ so that it links with compiled ASN.1.
1248 Added Explain-schema definitions and mapping routines. The following
1249 Explain categories have been implemented: AttributeDetails,
1250 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1252 Fixed minor bug in Windows version of Server Library.
1254 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1256 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1258 Added EXTERNAL: UNIverse Resource Report (non-standard).
1260 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1261 ENUMERATED and SET OF.
1263 * Added 'const' to some of the char pointer arguments for the
1264 functions, data1_read_node, data1_getelementbytagname,
1265 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1268 Fixed bug in data1_insert_taggeddata - the last_child member of
1269 parent wasn't initialised.
1271 * Changed data1_read_record and data1_read_node so that the supplied
1272 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1273 doesn't refer to any parts of the "SGML"-buffer.
1275 Fixed bug in server library (Windows version of statserv_remove).
1277 * Changed code so that it compiles as C++. The type definition
1278 of Odr_fun which is a member of Odr_arm was changed. The result is,
1279 that an explicit typecast is needed for the fun pointer when
1280 using Odr_arm - as in:
1281 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1283 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1285 Implemented the new structured date and time definition as approved
1286 by the ZIG. Added schemaId element to the specificTag in Espec-1
1287 (also approved at the last ZIG). Thanks to RVDM.
1289 Added some Object identifiers (RVDM).
1291 Changed the Update Extended Service (RVDM).
1293 Added command "refid" to client which specifies referenceId for
1294 the following requests.
1296 Implemented extended service handling for server. See ztest.c
1297 for an example as well as backend.h. New handlers are registerd
1298 in the Init handler.
1300 * Changed interface for sort in server.
1302 Added new members to statserv_options_block. It allows a server
1303 to read options from another source than just the command line. Thanks
1304 to Charles Woodfield.
1306 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1307 renamed to zboolean. Some C++ compilers complained about the name.
1309 Minor changes to gils.abs. Added index 's' (sort) on title
1310 and date/time-last-modified.
1312 --- 1.4pl2 1998/1/30
1314 Fixed bug in server library regarding inetd mode (-i). This bug
1315 was introduced by release 1.4.
1317 --- 1.4pl1 1998/1/29
1319 Added sort facility in client and backend server interface.
1321 Fixed problem with dependencies in Makefile(s).
1323 Fixed bugs for encoders/decoders of extended services and
1326 Implemented sub-tree feature for schemas. Sub-trees are
1327 referenced in *.abs-files. See explain.abs for an example
1328 of the use of this feature.
1330 Modified bib1.att; local attributes for ANY didn't include
1331 ANY itself (only affects use of the retrieval module).
1333 Fixed bug in plain SGML reader in function data1_read_node:
1334 tags with prefix "var" was incorrectly interpreted as variants.
1336 Added feature "sub-schemas" to enable references to - and definitions
1337 of - group of elements.
1339 * Removed member parent from type data1_element (in data1.h).
1341 Implemented function odr_nullval() that returns the value of
1344 * Removed member num_children from data1_node (in data1.h).
1346 Made NT service interface part of the server library. The
1347 function statserv_main uses the NT service when required and
1348 calls the statserv_start / statserv_close routines.
1350 Routine zget_SearchRequest and zget_PresentRequest fills
1351 resultSetName/Id member with "default" instead of "Default".
1353 Fixed memory leak in server. Request queue member wasn't freed.
1355 Fixed nmem_exit so that memory is freed.
1359 Revised the CCL parser utility to be thread safe.
1361 Added function, oid_ent_to_oid, to replace the function
1362 oid_getoidbyent, which is not thread safe.
1364 * Added nmem_init and nmem_exit to initialize and release
1365 NMEM resources. Function nmem_init should be called once in the
1366 initial thread before NMEM/ODR is used. statserv.c and client.c
1367 have been changed accordingly. The change was necessary to make
1368 NMEM thread safe. The NMEM memory pool is shared amongst threads
1369 in a process. Unix-based applications will still work fine without
1372 Added NT Services interface for the the Z39.50 (statserv) Server.
1373 Refer to the ztest.c source on the usage.
1375 Windows 95/NT port using MSVC5.0. Project files are included in the
1378 * Defined new 'global' handle for the retrieval (data1) system. The
1379 new handled, data1_handle, describes the state of the data1 system.
1380 This handle is passed as first argument to virtually all
1381 data1 related routines. The functions data1_create and data1_destroy
1382 creates and destroys a data1 handle respectively.
1384 Added ODR encode stream member to all backend request structures
1385 init, search, scan etc. This stream should be used to allocate all
1386 memory used for the response when thread safe operation is needed.
1388 Changed the comstack utility, cs_addstr, to be thread safe. The
1389 returned hostname string returned by the function is now part the
1392 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1393 function. The cs_straddr takes a COMSTACK handle as argument, so this
1394 function must be used after cs_create and before bind/connect.
1395 This function is thread safe.
1397 Moved test server to 'ztest' directory - generic server code still
1398 in 'server' directory.
1400 Made prefix query (pquery.c) utility thread safe.
1402 Added new function modifier YAZ_EXPORT to 'export' public DLL
1403 functions when using windows (see include/yconfig.h).
1405 Added definitions to the OID database (util/oid.c) (RVDM).
1407 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1409 Added call to ccl_rpn_delete in client program.
1411 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1412 release of RPN structure.
1414 Added support for C++, headers uses extern "C" for public definitions.
1415 With input from RVDM.
1417 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1418 Thanks to Ronald van der Meer (RVDM).
1420 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1422 Added support for private extensions to the OID database
1423 (oid_setprivateoids()). Thanks to RVDM.
1425 Added optional, physical ANY (key replication)
1427 Fixed null-reference problem in GRS-1 output filter.
1429 Proximity operator added to Prefix Query Format (PQF).
1431 In test client command "base" accepts multiple databases.
1433 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1437 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1439 Smallish bug-fixes in the new encoders/decoders (explain).
1441 Bug fixed in DeleteRequest.
1443 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1445 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1447 Added SOIF syntax (using private OID for now) to retrieval module and client.
1449 Added Update extended service.
1451 Added SearchResult-1 additional info structure.
1453 Added optional CCL (ISO8777) interpreter as separate module. Available
1456 --- 1.2 1996/6/10 (1st anniversary release)
1458 Added Summary record syntax. Lightly tested.
1460 Added OPAC record syntax. Untested.
1462 Added ResourceReport service encoders/decoders. Untested.
1464 Fixed bug in z_Unit - wrong tagging on unitSystem.
1466 Fixed bug in the DiagRecs decoder.
1468 Added options for max PDU size and session timeout to frontend-server.
1470 Added documentation of query-language parsers and other supporting utilities.
1472 [frontend-server] Added Attribute set to the bend_scanrequest API.
1474 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1475 surrogate diagnostics were generated.
1477 [retrieval] Allow multiple local values for attribute.
1479 [retrieval] Allow multiple attributes per element in .abs files. index type.
1481 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1483 --- 1.1pl2 1996/4/10
1485 Minor changes, mostly specific to Zebra's requirements (retrieval)
1489 Repaired bug in frontend server when running multiple listening
1490 endpoints in dynamic mode.
1492 z_External() now won't break if a known, ASN.1 value comes encapsulated
1493 in an octet-string. The value will pass through unmodified in an Odr_oct.
1495 Added a bit of code to the demo client to decode & display
1496 ASN.1-structured records represented in the octet-aligned branch of
1497 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1499 Added z_ext_getentbyref() to the ASN module. Doc updated.
1501 * Completed the SCAN definition in the ASN module. This may break SCAN
1502 code based on older YAZ-versions at compile-time. The fix is easy -
1505 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1506 under the SCAN definition. Remember to initialize this, server-people.
1508 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1509 that this does not extend to ODR and ASN.
1511 Comstack allows insertion of established socket (primarily for
1512 inetd-operation of servers). Doc updated.
1514 Front-end server can now start from the inetd in TCP mode. Doc
1517 --- 1.0pl4 1996/1/24
1521 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1522 the rank and record number.
1524 Adjustments to the frontend server.
1526 Fixed diagnostic BER dumper. It ignored the file argument.
1530 Various changes to retrieval module.
1532 Changed the union discriminators of the protocol files from enums to
1533 ints paired with #defines.
1535 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1538 *Changed operator in the RPN structure to 'roperator', again to avoid a
1541 Fixed problems in Explain decoders/encoders.
1543 --- 1.0pl2 1995/12/6
1545 Memory bug in log module fixed.
1547 --- 1.0pl1 1995/12/5
1549 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1551 Bug in Explain DatabaseInfo module fixed.
1553 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1557 The shift to v1.0 signals that we now consider the *core* functionality
1558 of YAZ reasonably stable (the core being more or less equivalent to
1559 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1560 tested (Explain not at all - though that will happen soonish).
1562 Minor changes to code to support Windows port.
1564 Various minor changes after we're getting to use GRS-1 & co. more.
1566 Added Espec-1 format.
1568 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1569 of the protocol and it cannot be selected when encoding (maps into 'string'
1570 when decoding). Needed to talk to some servers.
1572 Demo client can request simple element set names.
1574 Added Diagnostic Format encoders/decoders.
1576 Added simple Close handling to frontend server (no hooks for resource
1577 reporting yet), and demonstration client.
1579 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1581 --- 1.0b3 1995/08/24
1583 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1584 handled incorrectly when records were requested in the searchResponse. This
1585 will only affect you if you use the frontend-server.
1587 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1588 Test-client will ask for and print GRS1. Ztest will return dummy records
1591 Added Explain encoders/decoders to the service-level API. Untested.
1593 Added Extended Services: Item Order encoders and decoders to the Service-
1594 level API. Untested. We could use a recent copy of the pertinent bits
1595 of the ILL protocol to add those bits.
1597 Added diagnostic format 1 encoders/decoders to the service-level API.
1600 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1601 odr_cons.c, which causes a more correct output.
1603 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1604 was always set to 0 when no records were requested in the searchRequest.
1606 * Added better external-handling. This shouldn't harm old code that
1607 *encodes* externals. It can break code that looks for a
1608 'single-ASN1-type' representation, since those types that are known
1609 are now decoded immediately. Look at the SUTRS sample code in
1610 seshigh.c and client.c. Documentation updated.
1612 Handling of structured records in bend_fetchresponse. Length -1 marks
1613 structured record, type is deduced from format field.
1615 --- 1.0b2 1995/06/27
1616 Fairly quick maintenance release to add SUTRS support.
1618 Fixed handling of SUTRS records in the demonstration client.
1620 * Added format field to the bend_fetchrequest and bend_fetchresponce
1621 structures of the backend API (frontend server). When the record is
1622 returned, the value of the format field is mapped to an OID. The
1623 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1624 of the record. The special value VAL_NONE in the bend_request means
1625 that no specific format was requested by the client. Documentation
1626 updated accordingly. Test server (ztest) will return a fixed dummy
1627 SUTRS record if your client requests SUTRS.
1629 Documentation updated accordingly.
1631 You can now set external libraries and RANLIB support in the top-level
1635 First public release.
