1 Added 'exit' as synonym for 'quit' in yaz-client
3 Possible compatibility problems with earlier versions marked with '*'.
5 Added support for specifying srw resultset id + resultset TTL in a
6 Generic Frontend Server's search handler. Patch by Ko van der Sloot.
8 Do not build the separate Multi-threaded (MT) library libyazthread.la.
9 Instead make the library libyaz.la multi-threaded. Threading as a whole
10 can still be disabled by configure option --disable-threads. Previosly,
11 with older GLIBCs there were problems with MT libs under Apache. This
12 has now been fixed a long time ago.
14 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
17 CQL module modified to be case insensitive for relations/indexes/operations.
19 Fixed bug in CQL transform code: incorrect value relationModifieder
22 Added 'show all' command for yaz-client which retrieves all results
25 Added new yaz-client, xmles, which takes a (private) OID and
26 a document to be sent as an extended service request.
28 Describe new yaz-client commands wait_response and set_auto_wait.
30 Increase TCP/IP listener backlog from 3 (which I am guessing was
31 copied from the SunOS manual entry way back when) so SOMAXCONN, so
32 that the socket will queue as many incoming connections as it's able
33 to handle ongoing connections. In other words, it will never now
34 refuse a connection that it would be able to handle merely because
35 it's not got around to accepting() enough of the pending connections
36 yet. This is the behaviour anyway under Linux, where the listen()
37 argument is ignored; but not under BSD and on systems such as
38 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
39 YAZ-based servers should now be uniform across operating systems in
42 yaz-marcdump uses 64-bit file access on some systems. This is enabled
43 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
44 This allows yaz-marcdump to read large MARC batches (>2 GB).
46 Modified all YAZ source files - except the source which is auto-generated
47 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
52 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
53 MARC output rather than returning "new" buffer.
55 yaz-client warns about unknown init options.
57 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
61 Added support for SRW sort in Generic Frontend Server. Patch
62 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
63 sortKeys - or NULL if none is provided.
65 Fixed bug #307: It was impossible to specify indefinite/no timeout
66 for ZOOM_event. Special timeout value -1 now means indefinite timeout
69 Added support for multiple languages and charsets to be specified in
70 ZOOM. Each charset/language is separated by a blank. If negotiation is
71 in effect in init-response, Option
72 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
73 Code based on patch by Vasiliy Osadchuk.
75 Fixed bug #306: infinite recursion that occurred when calling
76 yaz_log_level_init as the first call (before other log level or
79 Fixed bug in scan handling in front end server: if preferred-Position-In-
80 Response was non-present, a NULL pointer referece was performed.
84 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
85 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
86 now defined for all those error codes. So instead of putting 109 in
87 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
88 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
90 Modified the yaz-marcdump utility to skip garbage bytes between MARC
93 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
95 Program yaz-client now exits and produces an error message if multiple
96 Z39.50 servers are specified on the command line (none or one allowed
99 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
104 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
106 Fixed bug #272: Preserve spacing for CCL terms.
110 Added support for virtual hosts and multiple backend servers for
111 the YAZ frontend server. The configution is XML based and
112 support specificition of CQL to RPN mappings and explain information.
113 See section "Virtual Hosts" in the YAZ manual.
115 Extended OPAC display utility. OPAC display utility renders
116 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
117 to supplement yaz_marc_decode_wrbuf.
119 Fixed a bug in MARC decoder that could caused it to crash for some
120 invalid MARC records. More diagnostics and warnings where added in
121 XML output (warnings, etc are stored in comments).
123 --- 2.0.34 2005/02/08
125 Fixes for UNIX domain sockets. Bug #261.
127 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
129 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
130 Added yaz_marc_subfield_str which defines subfield lead string which is
131 used in YAZ_MARC_LINE format. Default string is blank+$. Added
132 yaz_marc_endline_str which defines end of fields string used in
133 YAZ_MARC_LINE format. Default string is newline.
135 Experimental support for MarcXChange. This format can be produced
136 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
137 http://www.bs.dk/standards/MarcXchange.xsd
139 Added yaz-client commands scansize that sets maximum number of
140 entries to be returned by scan.
142 --- 2.0.32 2005/01/11
144 Added support for SRW scan in yaz-client and Generic Frontend Server.
146 * Added whereInList member to SRW Scan Term.
148 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
150 Fixed NMEM system to return aligned blocks on the smallest boundaries
151 that are suitably aligned for all possible types on the particular
152 architecture YAZ is being built for.
154 --- 2.0.30 2005/01/04
156 Fixed numerious warnings that was issued with newer versions of GCC.
158 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
159 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
162 Make YAZ Generic Frontend Server slightly faster.
164 Enhance (and reduce) logging for Generic Frontend Server.
166 Revert YAZ log system so that it flushes every write operation
167 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
169 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
170 instead of LOG_, due to name clash with syslog(3). LOG_ are still
171 present. New applications should define YAZ_USE_NEW_LOG=1 - this
172 will effectively disable old definitions.
174 --- 2.0.28 2004/11/09
176 Added yaz_log_time_format which specifies log format using
179 Added yaz_log_module_level which returns mask for a module. Value
180 is non-zero mask a if module is enabled; zero if disabled.
182 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
183 in include/yaz/cql.h.
185 Fixed bug #176: Dont throw diagnostics on empty SRU args.
187 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
189 Fixed bug #172: RPM builds does not enable SSL.
191 Doxyfile.in part of dist. Doxyfile generated by configure.
193 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
194 are given and the corresponding component does not exist.
196 Extend CCL documentation in YAZ reference. Describe r=r.
198 --- 2.0.26 2004/10/01
200 Fixed MARC->MARCXML conversion to properly deal with
201 fields, subfields, indicators having non-ASCII characters.
203 Fixed MARC->MARCXML conversion so that ASCII control characters
204 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
207 Added YAZ GFS support for conversion from Z39.50 surrogate
208 diagnostics to SRW surrogate diagnostics.
210 Bug fix: YAZ GFS did not return schema in explainResponse.
212 --- 2.0.25 2004/09/30
214 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
215 now converts recordSchema to elementSetName as well as schema URI.
217 Fixed bug in COMSTACK that prevented HTTP request packages from being
220 --- 2.0.24 2004/09/29
222 Added CCL facility r=r "range" which is similar to r=o "ordered" but
223 does not require white-space before and after the dash in a range, e.g.
224 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
227 Fixed a few AC_TRY_LINK configure tests that did not operate properly
228 due to new GCC removing "redundant" code.
230 Added yaz-client commands scanpos and scanstep that sets preferred
231 position and step-size for scan.
233 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
235 Added CCL utility ccl_qual_buf which parses one or more CCL
236 spec lines in a buffer.
238 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
239 of name and value - ignoring empty lines and comments.
241 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
243 Added odr_get_element_path which returns current element path for an
244 ODR handle. This utility is useful in error handling or user-defined
247 Added ODR_PRINT utility odr_set_stream which is is a more generic
248 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
249 to a write function and pointer to close function. The close function - if
250 non-NULL - will be called during odr_destroy.
252 Fixed bug in CCL parser where truncation char was not removed from
253 right side when truncation=both was in effect.
255 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
258 --- 2.0.23 2004/08/11
260 Fix buffer overrun in CQL parser when dealing with proximity (%).
262 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
263 to UTF-8/UCS conversion is now only based on codetables.xml.
265 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
267 --- 2.0.22 2004/08/06
269 Add support for more "commit changes" in ZOOM (uses Extended Services).
271 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
274 Yet another small fix for configure of SSL.
276 --- 2.0.21 2004/05/14
278 Fix SSL libs for configure when --with-openssl=DIR is given.
280 --- 2.0.20 2004/05/10
282 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
284 SSL comstack now uses yaz.pem certificate file on server side
285 by default. Certificate filename can be configured by calling
286 comstack function cs_set_ssl_certificate_file before cs_bind is used.
288 Fix bug regarding multiple calls to ZOOM_connection_connect.
290 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
292 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
293 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
295 ZOOM now allows inspection of X509 peer certificate for verification.
296 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
298 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
299 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
300 as "modular" but it simplifies things.
302 Added cs_get_peer_certificate to that returns peer X509 PEM.
304 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
305 NULL if SSL is unavailable.
307 Documentation about MARC decoding tools.
309 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
311 --- 2.0.19 2004/03/30
313 Rename CHANGELOG to NEWS to follow GNU style packing.
315 Fix bug with missing initialization of member in init_diagnostics.
316 This bug affects threaded version of GFS server.
318 --- 2.0.18 2004/03/20
320 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
323 Ensure zlib.dll is packed with Windows install.
325 --- 2.0.17 2004/03/17
327 Fix encoding of xsd:string to use text instead of CDATA.
329 Fix endless loop in CQL parser with unbalanced ".
331 Use a more compact way to store MARC-8 conversion tables.
333 --- 2.0.16 2004/03/16 Debian only
335 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
338 Update CQL parser to use new CQL 1.1 modifiers for booleans and
343 --- 2.0.15 2004/03/01
345 Another fix for decoding of XML packed records.
347 --- 2.0.14 2004/02/25
349 Fixes for Chunked encoding. White space not ignored after length spec.
351 Update NS and use default NS for SRW diagnostic elements.
353 --- 2.0.13 2004/02/23
355 Implement ZOOM_resultset_cache_reset which resets record cache.
357 Implement ZOOM_resultset_sort which sorts a result set.
359 Implement chunked HTTP transfer.
361 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
363 --- 2.0.12 2004/02/16
365 Added member 'schema' to bend_explain_rr structure so that backend
366 can specify explain record identifier. Defaults to Zeerex 2.0.
368 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
370 --- 2.0.11 2004/02/16
372 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
375 Added init command for yaz-client which sends "extra" init request.
377 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
378 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
380 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
382 Make ZOOM error code for "invalid query".
384 Fixed compilation for SSL which wasn't properly enabled for all platforms.
386 --- 2.0.10 2004/02/05
388 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
391 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
393 Added option -p <file> to make Generic Frontend Server to write PID file.
395 Added option -D to put Generic Frontend Server in background on its own.
397 Make ZOOM C recognize option "password". If unset, "pass" is used
398 (for backwards compatibility).
400 Fixed a bug in Generic Frontend Server that could make it crash if a
401 client sets characterSetNegotation bit, but didn't pass negotiation stuff
404 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
405 Must be issued before open, in order to be in effect.
407 --- 2.0.9-6 2004/01/12 Debian/Windows
409 Make the SRU server more picky WRT unknown params, etc.
411 Bug fix: ZOOM scan response didn't return displayTerm - when present.
413 New YAZ client command, options, that sets Z39.50 options.
415 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
416 options from a string of tokens (one token for each option bit).
418 Update SRW diagnostic code messages.
420 --- 2.0.9-5 2004/01/07 Debian/Windows
422 Handle user defined stylesheet for SRW/SRU.
424 --- 2.0.9-4 2004/01/06 Debian/Windows
426 Fix bug in decoding of Content-Length.
428 --- 2.0.9-3 2004/01/06 Debian/Windows
430 Fix a bug with decoding of XML packed records.
432 --- 2.0.9-2 2004/01/05 Debian only
434 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
436 Fix bug in SRW/SRU diagnostics decoding.
440 Fixed bug in Generic Frontend Server which could drop records exceeding
441 preferred message size. Reported and fixed by Irina Dijour.
443 Fixed calculation of package size for structured records in Generic
444 Frontend Server. Reported and fixed by Irina Dijour.
446 Fixed namespace for SRW/SRU diagnostics.
448 Fixed SEGV in yaz-client that occured for HTTP connection errors.
452 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
453 this version is incompatible with version 1.0 and older YAZ SRW/SRU
456 CQL changes to reflect recent changes to the specification:
457 * Documentation talks about context sets instead of index sets.
458 * Documentation talks about indexes instead of qualifiers.
459 * The CQL-to-PQF transformer's configuration file now uses
460 "index.set.name = <attributes>" instead of the old form
461 "qualifier.set.name = <attributes>". (Both forms are still
462 understood but the latter is deprecated.)
463 * CQL terms with no explicit index specified are now interpreted as
464 cql.serverChoice instead of srw.serverChoice (which of course
465 behaves exactly the same.)
469 MARC conversion can now generate ISO2709 output in another
470 character set. yaz-marcdump uses this facility if you invoke it
473 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
474 functions from there can be used from C++.
478 Frontend server now transfers memory from decoded packages to stream
481 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
482 references to show up.
484 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
485 the ZOOM Abstract API. The older names for the same options are still
486 also supported for the benefit of old applications.
488 ZOOM-C supports "implementationId" and "implementationVersion" options
489 to go along with "implementationName". These allow the user code to
490 specify identification strings to be sent to servers.
491 Add OID for the new ExtLite attribute set.
493 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
494 as requested/supplid by Ere Maijala <ere@atp.fi>
496 For generic frontend server, reverse the order of
497 "toolkit-supplied / application-supplied" strings sent as implementationId,
498 Name and Version. Also, remove the spaces around the slash. This brings
499 the GFS in line with the behaviour of ZOOM-C on the client side.
501 Add function ZOOM_scanset_display_term.
503 yaz-client shows scan displayTerm if present.
505 Utility yaz-iconv is now installed by default along with the man page
508 Extend configure check for OpenSSL to use pkg-config where available (such
511 Incorporate patch by Morten Bogeskov which allows a Unix file socket
512 server to specify uid/gid/mask for socket using the format
513 unix:[user=uid,][group=gid,][umask=mask,]file=path
514 If file= is omitted the existing format is assumed, e.g.
516 in which case the mask is 0666 (rw for everybody).
518 Major restructure of YAZ source. All source in libyaz is in src directory.
519 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
520 util (utility programs such as ASN.1 compiler, yaz-marcdump).
522 Added man page for utility yaz-marcdump (used to be called marcdump).
523 yaz-marcdump is installed by 'make install'.
525 Fixed a memory leak in Generic Frontend Server that occurred when decoding
526 of incoming package failed.
528 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
530 Change prototype of odr_perror: add const to message string.
532 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
534 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
535 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
536 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
537 DNS lookup. There should not be any compatibility problems with this
538 assuming that blocking=1 or 0 is used.
540 Fix bad reference in UNIX comstack in function cs_addrstr.
542 Fix for compilation on AIX.
544 The generic front-end server (server/seshigh.c) now supports returning
545 Init diagnostics to the client in User-information-field, in
546 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
551 Allow any CQL relation (not just all,any,exact,scr).
553 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
554 that features the same UI.
556 Implemented command update0 in YAZ client which is equivalent to
557 update but uses old of Ext Update ASN.1.
559 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
560 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
561 Previously no OID was used for this info.
563 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
564 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
565 returns 'malformed search term' otherwise.
567 SortResponse member resultCount now set to NULL in sort handler of
570 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
573 Add three new utility functions for translating OIDs between various
574 formats -- symbolic name such as "Usmarc", minus-1-terminated int
575 arrays and dotted strings such as "1.2.840.10003.9.5.1":
576 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
577 char *oid_to_dotstring(const int *oid, char *oidbuf);
578 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
580 Reverted modifications for ES Update definition for z_IU0Update
581 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
582 is back to YAZ 2.0.2.
584 String value attributes for CCL parser.
586 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
587 which their FirstSearch server returns in Init responses, sometimes
588 carrying useful diagnostic information when Init fails. This has the
589 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
590 "z39.50/oclcui.asn", where its definition is somewhat different from
591 what OCLC document on their web-site, as required to interoperate with
594 Support for anonymous authentication in yaz-client. Use the command
597 * Fix the OID of the Index Data-local "admin" Extended Service from
598 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
599 the 1000, which indicates a locally-defined OID, was a mistake.
603 Fix CCL directive @case handling so that it affects string match for
604 both CCL keywords and qualifiers.
606 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
607 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
608 Decoder has been updated with ASN.1 changes as listed in
609 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
610 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
611 z_IUUpdate, remains unchanged.
613 ZOOM_record_get may now return a record in a specific character set.
614 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
615 "from" is the character set of record as returned by target. "to" is
616 the character set to be returned. If omitted, "to" is UTF-8.
618 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
620 New ODR utility, odr_getelement, which returns name of element for
621 which encoding/decoding failed.
623 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
624 in cases where a required element was omitted.
626 Bug fix: some MARC8 sequences were not converted.
628 New ZOOM option "step" which specifies number of records to be
629 retrieved in one chunk. Used in conjunction with "start" and "count".
631 SRW support for yaz-client. Use scheme http: to use it, e.g.
634 yaz-client no longer does (un)intelligent character set conversions
635 by default. Can be enabled with charset and marc_charset commands.
637 xmalloc trace fix for 64-bit systems such as DEC alpha.
639 Solaris 2.6 compile fix.
641 New function, cql_strerror() translates SRW error codes, as returned
642 by cql_transform_error(), into human-readable English strings. Used
643 in yaz-client diagnostics when appropriate.
645 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
646 converts it into a type-1 query which is sent to the server. This
647 makes CQL available for use with all Z-servers, as opposed to the tiny
648 minority that can handle CQL queries themselves.
652 New Debian package layout similar to the Redhat Package layout.
654 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
655 and search result respectively.
659 Redhat package is now several packages: libyaz (runtime libraries),
660 libyaz-devel (development and documentation, and yaz (utility programs).
661 Package spec file by Morten Bøgeskov.
663 New member 'schema' in struct bend_fetch_rr which the name of requested
664 schema (SRW/SRU) for record (or NULL if none was given). The fetch
665 handler MAY set this to reflect the schema of the returned record.
667 New member 'display_term' in struct scan_entry. GFS now sets member entries
668 and allocates scan entries to be filled by user scan handler. In previous
669 version, entries member was allocated by the scan handler. That still works,
670 but the GFS will ignore member display_term - assuming it was NOT set by
671 the handler. The fact that the GFS now allocates the entries both allows
672 for new members and makes a scan handler easier to write.
674 Fix CQL lex buffer overflow.
676 SRW/SRU recordPacking. For SRW default recordPacking is string. For
677 SRU default recordPacking is string.
679 SRU protocol support for frontend server.
681 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
683 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
685 Added scan for the ZOOM shell (zoomsh).
689 * String Identifers for Schemas (Amendment 5).
690 http://lcweb.loc.gov/z3950/agency/amend/am5.html
691 Old definition for schema
692 Odr_oid *schema; /* OPT */
697 Z_InternationalString *uri;
698 #define Z_Schema_oid 1
699 #define Z_Schema_uri 2
702 * resultCount parameter to Sort Response (Amendment 1).
703 http://lcweb.loc.gov/z3950/agency/amend/am1.html
705 Support for SRW 1.0 over HTTP. This is an optional feature and
706 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
709 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
710 on the same port. SRW SearchRetrieveRequests are mapped
711 to bend_init,bend_search,bend_fetch,bend_close.
713 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
715 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
716 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
718 ZOOM connections are SRW based if schem http is used for hostname
719 in connect, e.g. z = ZOOM_connection_new("http://myserver");
720 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
722 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
723 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
724 distance=n, order=true/false, relation=le, prox unit=word. If
725 n is omitted, distance 1 is used.
727 Fixed problem with C compiler include path in wrong order.
729 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
730 on Solaris. Patch from Ko van der Sloot.
732 New MARC decode API. All new functions operate on a yaz_marc_t
733 handle. The most important new functions are: yaz_marc_create,
734 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
735 decode and destroy respectively. Decoder can produce formats
736 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
737 include/yaz/marcdisp.h.
739 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
740 to UTF-8, UCS-32, wchar_t or Latin-1.
742 * Prototypes for yaz_iconv_-functions moved to separate header
743 include/yaz/yaz-iconv.h.
745 Make a few private functions 'static' in unix.c. This prevents
746 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
748 For ZOOM connection, the options targetImplementation{Id,Name,Version}
749 are set when Init Response is received.
751 New function ZOOM_connection_error_x similar to ZOOM_connection_error
752 but returns diagnostic set as well.
754 New function yaz_strerror which is a portable wrapper for
755 strerror/strerror_r/GetLastMessage.
757 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
758 is returned for MARC. If type is "oai", then OAI MARC is returned.
760 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
765 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
767 Fix bad race conditions on SIGTERM and terminate gracefully in
770 Move retrieval (data1) module to Zebra since nobody seems to be
773 Add GRS-1 render for ZOOM using same format as yaz-client.
777 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
779 Fix broken ESpec handling in data1 module.
781 SGML reader parses comments and makes them part of the data1 tree.
783 Added several type casts so that YAZ compiles as C++ code.
785 ZOOM didn't handle PDU encoding failures properly.
787 Added more Bib-1 diagnostics (approved extensions).
789 GNU configure: better check for iconv.
791 More portable use of accept, getpeername. Check for socklen_t. Use
792 int/size_t if socklen_t is not defined.
796 PQF parser rejects bad queries - including those with extra
797 characters in them. PQF parser used to silently ignore that.
798 Cleaner API for PQF added, which allows you to get detailed
799 error information for bad queries (see yaz/pquery.h).
801 Fixed bug in ZOOM_record_get for type "database".
803 Implemented mini iconv library supporting conversions between
804 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
806 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
810 Fixed ZOOM C record cache so that preferredRecordSyntax and
811 elementSetName is used to check for already fetched records.
815 Added three members in bend_initrequest structure to facilitate
816 character set negotiation.
818 Fixed a bug in frontend server that could cause indefinite
819 loops under rare conditions.
821 Revised character set utilities (charneg.h) so that encoding
822 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
824 For PQF, directive @term <type> sets term type for Scan/Search.
825 Here <type> is general, string, numeric, null. The term type
826 is inherited - just like @attr.
828 New call odr_set_charset that sets character set conversion for
829 international-strings on a ODR stream. Prototype is:
830 int odr_set_charset(ODR o, const char *to, const char *from);
831 The InternationalString is still represented as C string in YAZ
832 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
833 won't). On the protocol level, you can use any encoding.
835 Support for UNIX sockets in ZOOM.
837 Solaris recv sometimes returns errno == ENOENT. It is treated as
838 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
840 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
841 both client and server. Code by Morten Bøgeskov.
845 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
846 that they can be used directly from Visual Basic. You must recompile
847 your windows APP if you're using ZOOM.
849 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
850 Commands "lang" and "charset" sets language and character set respectively.
851 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
852 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
854 Attributes from multiple CCL fields may be OR'ed rather than merged
855 using directive "@field or". Fields are still merged by default -
856 equivalent to "@field merge".
858 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
861 Fixed bug in zget for parameter ExtendedServicesResponse.
867 Added PQF feature: '@attr type=value' may be written as '@type=value'.
869 Client displays USR.1:SearchResult-1 (hits per term).
871 Additional Search Info for search in Generic Frontend Server.
873 Fixed CCL parsing of "field=s".
875 WIN32 installer - using the excellent NSIS software from nullsoft.
877 Fixed CCL parsing of "field = - <number>".
879 Added function yaz_marc_decode that decodes MARC for line mode
880 display or XML (similar to that used by JZKit).
882 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
883 Z39.50. But ISO/ILL was, however.
885 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
886 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
888 http://lcweb.loc.gov/z3950/agency/amend/am2.html
889 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
893 New YAZ client features: Command completion and new commands:
894 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
895 Code provided by Jacob Poulsen.
897 New call oid_trav, that visits all registered OIDs via callback.
899 Function ZOOM_record_get now returns const char pointer rather than
900 void pointer. It saves a lot of type casts.
902 For YAZ client, command "auth" now allows you to set authentication
903 in IdPass style. It is enabled when three tokens are given - order
904 is user, group and password.
906 Fix memory leaks in MARC record handling for ZOOM.
908 New option for YAZ client, -k <kilobytes> that sets
909 maximum record size. Similar to -k option for generic frontend
910 server and yaz-ztest.
912 More fixes for scan. Non-zero stepSize handled. OID's fixes.
914 Prefix query parser reports "fail" when bad attribute set is given.
916 Fix in MARC decoder. Proximity logging. Fix for attribute set
917 in scan handler for server. Patches by Shigeru Ishida.
919 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
922 Configure option --with-openssl=<dir> now works when a directory is
923 specified. Patch provided by Morten Bøgeskov.
925 New option for YAZ client, -u <auth>, that sets authentication.
927 ZOOM fix: error information was sometimes "missing", since error
928 was cleared/reset too when it shouldn't.
930 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
934 Scan for ZOOM API. New object ZOOM_scanset. New functions
935 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
936 ZOOM_scanset_destroy.
938 New ZOOM function, ZOOM_connection_last_event, that returns type
939 of last event (such as "receive data", "send data", "apdu received",
942 New ZOOM option, schema, that specifies schema for retrieval.
944 New CCL feature. Qualifiers can be aliases for one or more
945 other qualifiers (if more than one is given, OR is used).
947 ZOOM uses named result sets if target supports it.
949 Two new YAZ client commands: . (dot, which sources a script of YAZ
950 client commands), and ! (to execute shell command.). Implemented
953 Working on Debian packages.
957 YAZ client enables named result sets only if target supports it.
959 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
961 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
962 with key="host" to get same result.
964 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
965 Function Z3950_resultset_record(s) returns references to records
966 "owned" by resultset. To become owner use Z3950_record_clone.
968 Function z_ext_record handles Extended Services. Thanks to
973 CCL Parser fix: ignore token comma when dealing with and-lists.
975 Documentation updates for COMSTACK.
977 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
978 Changed prototype Z3950_records. For some functions, int parameters
979 were changed to size_t.
981 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
984 New MARC decode/display function, marc_display_exl, which properly rejects
985 non-ISO2709 records. YAZ client uses it.
989 Fix bug: local attribute set wasn't set correctly in PQF strings.
993 * Old Z39.50 codecs no longer supported.
995 Added ZOOM C binding. See http://zoom.z3950.org/
997 Renamed states for COMSTACKs to avoid confusion with events.
999 Implemented cs_look and proper cs_rcvconnect.
1001 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1003 Configure detects POSIX threads on OpenBSD.
1005 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1006 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1008 When error is returned from present handler, non-surrogate diagnostic
1009 is returned in present response (and fetch handler is no longer called).
1011 * Minor adjustments to pquery parser (PQF). Token characters may be
1012 escaped by using backslash (C-style).
1014 PQF parser allows string attribute values to be specified. For @attr,
1015 non-numeric characters after the equal-sign are treated as strings
1016 (e.g. @attr 9=title).
1018 CCL trunction character may be defined (@truncation in file)
1020 * function zget_ExtendedServicesRequest sets waitAction to
1021 waitIfPossible (was wait).
1023 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1026 CCL operator names may be set in field definition files (CCL_bibset).
1027 See ccl/bib1 for an example.
1029 Fixes in ASN.1 compiler for C++ compatibility.
1031 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1032 and "op_or" to avoid conflict with C++.
1034 Fixed problem with GNU readline detection on Redhat 7.0.
1036 Added step-size for Scan backend handler.
1038 Fixed bug that made the frontend server crash when no attribute
1039 set was specified for scan.
1041 Front-end server automatically switches to original working directory
1042 when installed as an NT service. Previously -w had to be specified to
1045 Added extended attributes for retrieval module (data1), so that data1
1046 records carry d1_readXML/SGML attributes. d1_read also supports
1047 null-data rules ( <tag/>)
1049 On UNIX when POSIX threads are available, a separate library libyazthread
1050 is created. Programmers should link with that library and the yaz library
1051 when using threads. The reason for the split was that some applications
1052 on Linux, such as Apache, doesn't work well when using shared objects that
1055 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1056 (or any frontend server) in SSL mode by specifying ssl: followed by
1057 address. Only tested on UNIX.
1059 Added feature for CCL module. Virtual structure s=al or s=ol generates
1060 and-list and or-list respectively instead of phrase search.
1064 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1065 log_mask_str. This was done to avoid name conflicts with other libraries
1066 (such as other PHP extensions).
1068 Added raw OID member for preferred record syntax (request_format_raw)
1069 and returned record syntax (output_format_raw) for backend fetch method.
1071 Config file yaz-config now accepts options so that it returns specific
1072 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1074 Shared library support for UNIX using GNU libtool.
1076 * Modified backend interface. Request/Response struct's replaced by
1077 one read/write C struct. For example bend_fetchrequest and
1078 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1079 Every handler - even search has to be registered in bend_init
1080 handler. This means that the YAZ library no longer refers to
1081 external functions and it makes it possible to make the whole
1082 thing a single DLL/SO.
1084 Added Segment handler for backend server.
1086 Added Zmbol/Zebra administrative functions to YAZ client.
1088 Threaded frontend server on UNIX (when POSIX Threads are available).
1089 Starting the server with option -T enables multi-threading.
1093 Added configure option --enable-comp/disable-comp to control use
1094 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1095 located in sub directory asn.
1097 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1098 in ${exec_prefix}/bin along with the other programs yaz-client and
1101 GNU automake used to maintain makefiles.
1103 Added several OID's.
1105 Changed retrieval module so that we can load records with no abstract
1106 syntax defined. Tagpaths in these records are fully composed of string
1109 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1113 On UNIX, the generated makefile now supports a proper 'make install'.
1114 The prefix can be set via GNU configure to set the install location
1115 (default is /usr/local).
1117 * YAZ programs client and ztest were renamed to yaz-client and
1118 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1119 locations, such as /usr/bin,/usr/local/bin,etc.
1121 * YAZ Header files were moved from include to include/yaz. YAZ Header
1122 files are referred to as include <yaz/log.h> rather than <log.h>.
1123 The YAZ include path (-I ..) is therefore the same as before. Programmers
1124 should update their #include statements or use -Ipath/include/yaz
1125 instead. The main motivation for doing this change is that YAZ header files
1126 can be installed in "standard" locations /usr/include,/usr/local/include
1127 without introducing conflicts, since ALL YAZ header files are stored
1128 in subdirectory yaz (under /usr/include for example).
1130 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1131 rather than project/workspace files. We switched because project files
1132 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1135 Changed name of logging function, logf, to yaz_log, to prevent name
1136 clash with some math-log functions. The YAZ header log.h defines logf
1137 to yaz_log (#define) so there should be no incompatibilities by this
1140 Added bend_start/bend_stop handlers for server. These handler are
1141 called on start/stop of server. For windows they are called whenever
1142 a service is started/stopped.
1144 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1145 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1146 in util/yc.tcl. The auto-generated C code structures are, in a few
1147 cases, incompatible with the old decoders. There are differences in the
1148 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1149 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1150 The preprocessor variable ASN_COMPILED is defined when the compiled
1151 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1152 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1153 wish to use the old encoders/decoders you can specify --disable-yc
1156 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1157 version so that it supports both new - and old version of DB Update
1159 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1160 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1161 change. The name parameter can be set to 0 in which no name is specified
1162 for the construction. The macros odr_implicit and odr_explicit sets name
1163 parameter to zero for the construction involved. New macros
1164 odr_implicit_tag and odr_explicit_tag are similar to the others,
1165 except that a name parameter is added. For programmers' that don't use
1166 ODR they probably only need to change the call to z_APDU and z_External.
1168 Added access control facility by interfacing the TCP wrapper library.
1169 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1170 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1171 name of the daemon and enables the access control as specified in
1172 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1174 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1175 den Dool <H.M.vdnDool@kub.nl>.
1177 Added reference ID parameter to most functions in server API - refer
1178 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1180 Changed name of ccl library to libccl.a (was ccl.a).
1182 Fixed bug in decoder for Explain (Category TargetInfo).
1184 Added support for GNU readline in client. Thanks to Jacob Poulsen
1185 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1187 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1188 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1189 IMPLEMENTATION! This change was made to the development version before
1190 the ZIG decided to retract the amendment. If any users MUST be
1191 compatible with the original Update definition, PLEASE CONTACT US, and
1192 we will include a separate definition corresponding to the old Update
1193 ES. Note that because of the change to the ASN.1 of the
1194 TaskPackageRecordStructure we cannot define a single structure that
1195 will support both versions.
1197 * Added const modifier to buffer parameter for some ODR/BER encoding
1198 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1199 completeWAIS, odr_dumpBER.
1201 Fixed bug in client.c which caused a crash when a scanResponse didn't
1202 contain positionOfTerm.
1204 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1205 * will cause an error in a client if a non-YAZ target sends both a
1206 * list of Scan entries and non-surrogate diagnostics.
1208 Retrieval module enhancements. Tag sets may be typed in the reference
1209 to it. From the .abs-file the "tagset" directive takes a third optional
1210 integer type for the tag set referenced. From a .tag-file the "include"
1211 directive takes a third optional type as well. The old "type" directive
1212 in the tag set itself is still recognized but acts as the default type
1215 Backend interface change. Individual Scan terms returned from bend_scan
1216 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1217 in include/backend.h.
1219 Retrieval module enhancements. Multiple tag sets and attribute sets may
1220 be specified in abstract syntax specs. Revised the error/warning for
1221 logging messages reported by the retrieval module when reading the
1224 Object Identifier system (oid_..) changed. The API is backwards
1225 compatible but the oid-routines now allocates new OID's when needed.
1226 Raw OID's may be specified in oid_getvalbyname.
1228 YAZ now uses GNU configure to generate Makefile(s).
1230 * Minor changes in some of the member names of DeleteResultSetRequest and
1231 DeleteResultSetResponse. See include/proto.h.
1233 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1234 and added member 'languages' in TargetInfo (which was missing).
1236 Changed the way attribute sets are handled in the retrieval
1237 module. These are now cached, just like the abstract syntaxes
1240 Changed YAZ so that it links with compiled ASN.1.
1242 Added Explain-schema definitions and mapping routines. The following
1243 Explain categories have been implemented: AttributeDetails,
1244 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1246 Fixed minor bug in Windows version of Server Library.
1248 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1250 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1252 Added EXTERNAL: UNIverse Resource Report (non-standard).
1254 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1255 ENUMERATED and SET OF.
1257 * Added 'const' to some of the char pointer arguments for the
1258 functions, data1_read_node, data1_getelementbytagname,
1259 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1262 Fixed bug in data1_insert_taggeddata - the last_child member of
1263 parent wasn't initialised.
1265 * Changed data1_read_record and data1_read_node so that the supplied
1266 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1267 doesn't refer to any parts of the "SGML"-buffer.
1269 Fixed bug in server library (Windows version of statserv_remove).
1271 * Changed code so that it compiles as C++. The type definition
1272 of Odr_fun which is a member of Odr_arm was changed. The result is,
1273 that an explicit typecast is needed for the fun pointer when
1274 using Odr_arm - as in:
1275 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1277 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1279 Implemented the new structured date and time definition as approved
1280 by the ZIG. Added schemaId element to the specificTag in Espec-1
1281 (also approved at the last ZIG). Thanks to RVDM.
1283 Added some Object identifiers (RVDM).
1285 Changed the Update Extended Service (RVDM).
1287 Added command "refid" to client which specifies referenceId for
1288 the following requests.
1290 Implemented extended service handling for server. See ztest.c
1291 for an example as well as backend.h. New handlers are registerd
1292 in the Init handler.
1294 * Changed interface for sort in server.
1296 Added new members to statserv_options_block. It allows a server
1297 to read options from another source than just the command line. Thanks
1298 to Charles Woodfield.
1300 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1301 renamed to zboolean. Some C++ compilers complained about the name.
1303 Minor changes to gils.abs. Added index 's' (sort) on title
1304 and date/time-last-modified.
1306 --- 1.4pl2 1998/1/30
1308 Fixed bug in server library regarding inetd mode (-i). This bug
1309 was introduced by release 1.4.
1311 --- 1.4pl1 1998/1/29
1313 Added sort facility in client and backend server interface.
1315 Fixed problem with dependencies in Makefile(s).
1317 Fixed bugs for encoders/decoders of extended services and
1320 Implemented sub-tree feature for schemas. Sub-trees are
1321 referenced in *.abs-files. See explain.abs for an example
1322 of the use of this feature.
1324 Modified bib1.att; local attributes for ANY didn't include
1325 ANY itself (only affects use of the retrieval module).
1327 Fixed bug in plain SGML reader in function data1_read_node:
1328 tags with prefix "var" was incorrectly interpreted as variants.
1330 Added feature "sub-schemas" to enable references to - and definitions
1331 of - group of elements.
1333 * Removed member parent from type data1_element (in data1.h).
1335 Implemented function odr_nullval() that returns the value of
1338 * Removed member num_children from data1_node (in data1.h).
1340 Made NT service interface part of the server library. The
1341 function statserv_main uses the NT service when required and
1342 calls the statserv_start / statserv_close routines.
1344 Routine zget_SearchRequest and zget_PresentRequest fills
1345 resultSetName/Id member with "default" instead of "Default".
1347 Fixed memory leak in server. Request queue member wasn't freed.
1349 Fixed nmem_exit so that memory is freed.
1353 Revised the CCL parser utility to be thread safe.
1355 Added function, oid_ent_to_oid, to replace the function
1356 oid_getoidbyent, which is not thread safe.
1358 * Added nmem_init and nmem_exit to initialize and release
1359 NMEM resources. Function nmem_init should be called once in the
1360 initial thread before NMEM/ODR is used. statserv.c and client.c
1361 have been changed accordingly. The change was necessary to make
1362 NMEM thread safe. The NMEM memory pool is shared amongst threads
1363 in a process. Unix-based applications will still work fine without
1366 Added NT Services interface for the the Z39.50 (statserv) Server.
1367 Refer to the ztest.c source on the usage.
1369 Windows 95/NT port using MSVC5.0. Project files are included in the
1372 * Defined new 'global' handle for the retrieval (data1) system. The
1373 new handled, data1_handle, describes the state of the data1 system.
1374 This handle is passed as first argument to virtually all
1375 data1 related routines. The functions data1_create and data1_destroy
1376 creates and destroys a data1 handle respectively.
1378 Added ODR encode stream member to all backend request structures
1379 init, search, scan etc. This stream should be used to allocate all
1380 memory used for the response when thread safe operation is needed.
1382 Changed the comstack utility, cs_addstr, to be thread safe. The
1383 returned hostname string returned by the function is now part the
1386 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1387 function. The cs_straddr takes a COMSTACK handle as argument, so this
1388 function must be used after cs_create and before bind/connect.
1389 This function is thread safe.
1391 Moved test server to 'ztest' directory - generic server code still
1392 in 'server' directory.
1394 Made prefix query (pquery.c) utility thread safe.
1396 Added new function modifier YAZ_EXPORT to 'export' public DLL
1397 functions when using windows (see include/yconfig.h).
1399 Added definitions to the OID database (util/oid.c) (RVDM).
1401 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1403 Added call to ccl_rpn_delete in client program.
1405 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1406 release of RPN structure.
1408 Added support for C++, headers uses extern "C" for public definitions.
1409 With input from RVDM.
1411 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1412 Thanks to Ronald van der Meer (RVDM).
1414 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1416 Added support for private extensions to the OID database
1417 (oid_setprivateoids()). Thanks to RVDM.
1419 Added optional, physical ANY (key replication)
1421 Fixed null-reference problem in GRS-1 output filter.
1423 Proximity operator added to Prefix Query Format (PQF).
1425 In test client command "base" accepts multiple databases.
1427 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1431 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1433 Smallish bug-fixes in the new encoders/decoders (explain).
1435 Bug fixed in DeleteRequest.
1437 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1439 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1441 Added SOIF syntax (using private OID for now) to retrieval module and client.
1443 Added Update extended service.
1445 Added SearchResult-1 additional info structure.
1447 Added optional CCL (ISO8777) interpreter as separate module. Available
1450 --- 1.2 1996/6/10 (1st anniversary release)
1452 Added Summary record syntax. Lightly tested.
1454 Added OPAC record syntax. Untested.
1456 Added ResourceReport service encoders/decoders. Untested.
1458 Fixed bug in z_Unit - wrong tagging on unitSystem.
1460 Fixed bug in the DiagRecs decoder.
1462 Added options for max PDU size and session timeout to frontend-server.
1464 Added documentation of query-language parsers and other supporting utilities.
1466 [frontend-server] Added Attribute set to the bend_scanrequest API.
1468 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1469 surrogate diagnostics were generated.
1471 [retrieval] Allow multiple local values for attribute.
1473 [retrieval] Allow multiple attributes per element in .abs files. index type.
1475 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1477 --- 1.1pl2 1996/4/10
1479 Minor changes, mostly specific to Zebra's requirements (retrieval)
1483 Repaired bug in frontend server when running multiple listening
1484 endpoints in dynamic mode.
1486 z_External() now won't break if a known, ASN.1 value comes encapsulated
1487 in an octet-string. The value will pass through unmodified in an Odr_oct.
1489 Added a bit of code to the demo client to decode & display
1490 ASN.1-structured records represented in the octet-aligned branch of
1491 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1493 Added z_ext_getentbyref() to the ASN module. Doc updated.
1495 * Completed the SCAN definition in the ASN module. This may break SCAN
1496 code based on older YAZ-versions at compile-time. The fix is easy -
1499 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1500 under the SCAN definition. Remember to initialize this, server-people.
1502 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1503 that this does not extend to ODR and ASN.
1505 Comstack allows insertion of established socket (primarily for
1506 inetd-operation of servers). Doc updated.
1508 Front-end server can now start from the inetd in TCP mode. Doc
1511 --- 1.0pl4 1996/1/24
1515 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1516 the rank and record number.
1518 Adjustments to the frontend server.
1520 Fixed diagnostic BER dumper. It ignored the file argument.
1524 Various changes to retrieval module.
1526 Changed the union discriminators of the protocol files from enums to
1527 ints paired with #defines.
1529 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1532 *Changed operator in the RPN structure to 'roperator', again to avoid a
1535 Fixed problems in Explain decoders/encoders.
1537 --- 1.0pl2 1995/12/6
1539 Memory bug in log module fixed.
1541 --- 1.0pl1 1995/12/5
1543 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1545 Bug in Explain DatabaseInfo module fixed.
1547 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1551 The shift to v1.0 signals that we now consider the *core* functionality
1552 of YAZ reasonably stable (the core being more or less equivalent to
1553 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1554 tested (Explain not at all - though that will happen soonish).
1556 Minor changes to code to support Windows port.
1558 Various minor changes after we're getting to use GRS-1 & co. more.
1560 Added Espec-1 format.
1562 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1563 of the protocol and it cannot be selected when encoding (maps into 'string'
1564 when decoding). Needed to talk to some servers.
1566 Demo client can request simple element set names.
1568 Added Diagnostic Format encoders/decoders.
1570 Added simple Close handling to frontend server (no hooks for resource
1571 reporting yet), and demonstration client.
1573 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1575 --- 1.0b3 1995/08/24
1577 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1578 handled incorrectly when records were requested in the searchResponse. This
1579 will only affect you if you use the frontend-server.
1581 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1582 Test-client will ask for and print GRS1. Ztest will return dummy records
1585 Added Explain encoders/decoders to the service-level API. Untested.
1587 Added Extended Services: Item Order encoders and decoders to the Service-
1588 level API. Untested. We could use a recent copy of the pertinent bits
1589 of the ILL protocol to add those bits.
1591 Added diagnostic format 1 encoders/decoders to the service-level API.
1594 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1595 odr_cons.c, which causes a more correct output.
1597 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1598 was always set to 0 when no records were requested in the searchRequest.
1600 * Added better external-handling. This shouldn't harm old code that
1601 *encodes* externals. It can break code that looks for a
1602 'single-ASN1-type' representation, since those types that are known
1603 are now decoded immediately. Look at the SUTRS sample code in
1604 seshigh.c and client.c. Documentation updated.
1606 Handling of structured records in bend_fetchresponse. Length -1 marks
1607 structured record, type is deduced from format field.
1609 --- 1.0b2 1995/06/27
1610 Fairly quick maintenance release to add SUTRS support.
1612 Fixed handling of SUTRS records in the demonstration client.
1614 * Added format field to the bend_fetchrequest and bend_fetchresponce
1615 structures of the backend API (frontend server). When the record is
1616 returned, the value of the format field is mapped to an OID. The
1617 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1618 of the record. The special value VAL_NONE in the bend_request means
1619 that no specific format was requested by the client. Documentation
1620 updated accordingly. Test server (ztest) will return a fixed dummy
1621 SUTRS record if your client requests SUTRS.
1623 Documentation updated accordingly.
1625 You can now set external libraries and RANLIB support in the top-level
1629 First public release.
