1 Fixed bug #416: First/second comb characters not handled in the
2 MARC-8 to UTF-8 conversion. Patch by Raj Patel.
4 Added option -m to GFS to control formatting of timestamps in log file.
6 Added 'exit' as synonym for 'quit' in yaz-client
8 Added support for specifying SRW resultSetId + resultSetIdleTime in a
9 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
10 for the new members. Patch by Ko van der Sloot.
12 Added support for SRU POST. It is supported for content-type
13 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
15 Do not build the separate Multi-threaded (MT) library libyazthread.la.
16 Instead make the library libyaz.la multi-threaded. Threading as a whole
17 can still be disabled by configure option --disable-threads. Previosly,
18 with older GLIBCs there were problems with MT libs under Apache. This
19 has now been fixed a long time ago.
21 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
24 CQL module modified to be case insensitive for relations/indexes/operations.
26 Fixed bug in CQL transform code: incorrect value relationModifieder
29 Added 'show all' command for yaz-client which retrieves all results
32 Added new yaz-client, xmles, which takes a (private) OID and
33 a document to be sent as an extended service request.
35 Describe new yaz-client commands wait_response and set_auto_wait.
37 Increase TCP/IP listener backlog from 3 (which I am guessing was
38 copied from the SunOS manual entry way back when) so SOMAXCONN, so
39 that the socket will queue as many incoming connections as it's able
40 to handle ongoing connections. In other words, it will never now
41 refuse a connection that it would be able to handle merely because
42 it's not got around to accepting() enough of the pending connections
43 yet. This is the behaviour anyway under Linux, where the listen()
44 argument is ignored; but not under BSD and on systems such as
45 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
46 YAZ-based servers should now be uniform across operating systems in
49 yaz-marcdump uses 64-bit file access on some systems. This is enabled
50 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
51 This allows yaz-marcdump to read large MARC batches (>2 GB).
53 Modified all YAZ source files - except the source which is auto-generated
54 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
59 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
60 MARC output rather than returning "new" buffer.
62 yaz-client warns about unknown init options.
64 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
68 Added support for SRW sort in Generic Frontend Server. Patch
69 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
70 sortKeys - or NULL if none is provided.
72 Fixed bug #307: It was impossible to specify indefinite/no timeout
73 for ZOOM_event. Special timeout value -1 now means indefinite timeout
76 Added support for multiple languages and charsets to be specified in
77 ZOOM. Each charset/language is separated by a blank. If negotiation is
78 in effect in init-response, Option
79 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
80 Code based on patch by Vasiliy Osadchuk.
82 Fixed bug #306: infinite recursion that occurred when calling
83 yaz_log_level_init as the first call (before other log level or
86 Fixed bug in scan handling in front end server: if preferred-Position-In-
87 Response was non-present, a NULL pointer referece was performed.
91 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
92 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
93 now defined for all those error codes. So instead of putting 109 in
94 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
95 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
97 Modified the yaz-marcdump utility to skip garbage bytes between MARC
100 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
102 Program yaz-client now exits and produces an error message if multiple
103 Z39.50 servers are specified on the command line (none or one allowed
106 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
111 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
113 Fixed bug #272: Preserve spacing for CCL terms.
117 Added support for virtual hosts and multiple backend servers for
118 the YAZ frontend server. The configution is XML based and
119 support specificition of CQL to RPN mappings and explain information.
120 See section "Virtual Hosts" in the YAZ manual.
122 Extended OPAC display utility. OPAC display utility renders
123 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
124 to supplement yaz_marc_decode_wrbuf.
126 Fixed a bug in MARC decoder that could caused it to crash for some
127 invalid MARC records. More diagnostics and warnings where added in
128 XML output (warnings, etc are stored in comments).
130 --- 2.0.34 2005/02/08
132 Fixes for UNIX domain sockets. Bug #261.
134 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
136 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
137 Added yaz_marc_subfield_str which defines subfield lead string which is
138 used in YAZ_MARC_LINE format. Default string is blank+$. Added
139 yaz_marc_endline_str which defines end of fields string used in
140 YAZ_MARC_LINE format. Default string is newline.
142 Experimental support for MarcXChange. This format can be produced
143 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
144 http://www.bs.dk/standards/MarcXchange.xsd
146 Added yaz-client commands scansize that sets maximum number of
147 entries to be returned by scan.
149 --- 2.0.32 2005/01/11
151 Added support for SRW scan in yaz-client and Generic Frontend Server.
153 * Added whereInList member to SRW Scan Term.
155 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
157 Fixed NMEM system to return aligned blocks on the smallest boundaries
158 that are suitably aligned for all possible types on the particular
159 architecture YAZ is being built for.
161 --- 2.0.30 2005/01/04
163 Fixed numerious warnings that was issued with newer versions of GCC.
165 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
166 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
169 Make YAZ Generic Frontend Server slightly faster.
171 Enhance (and reduce) logging for Generic Frontend Server.
173 Revert YAZ log system so that it flushes every write operation
174 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
176 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
177 instead of LOG_, due to name clash with syslog(3). LOG_ are still
178 present. New applications should define YAZ_USE_NEW_LOG=1 - this
179 will effectively disable old definitions.
181 --- 2.0.28 2004/11/09
183 Added yaz_log_time_format which specifies log format using
186 Added yaz_log_module_level which returns mask for a module. Value
187 is non-zero mask a if module is enabled; zero if disabled.
189 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
190 in include/yaz/cql.h.
192 Fixed bug #176: Dont throw diagnostics on empty SRU args.
194 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
196 Fixed bug #172: RPM builds does not enable SSL.
198 Doxyfile.in part of dist. Doxyfile generated by configure.
200 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
201 are given and the corresponding component does not exist.
203 Extend CCL documentation in YAZ reference. Describe r=r.
205 --- 2.0.26 2004/10/01
207 Fixed MARC->MARCXML conversion to properly deal with
208 fields, subfields, indicators having non-ASCII characters.
210 Fixed MARC->MARCXML conversion so that ASCII control characters
211 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
214 Added YAZ GFS support for conversion from Z39.50 surrogate
215 diagnostics to SRW surrogate diagnostics.
217 Bug fix: YAZ GFS did not return schema in explainResponse.
219 --- 2.0.25 2004/09/30
221 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
222 now converts recordSchema to elementSetName as well as schema URI.
224 Fixed bug in COMSTACK that prevented HTTP request packages from being
227 --- 2.0.24 2004/09/29
229 Added CCL facility r=r "range" which is similar to r=o "ordered" but
230 does not require white-space before and after the dash in a range, e.g.
231 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
234 Fixed a few AC_TRY_LINK configure tests that did not operate properly
235 due to new GCC removing "redundant" code.
237 Added yaz-client commands scanpos and scanstep that sets preferred
238 position and step-size for scan.
240 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
242 Added CCL utility ccl_qual_buf which parses one or more CCL
243 spec lines in a buffer.
245 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
246 of name and value - ignoring empty lines and comments.
248 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
250 Added odr_get_element_path which returns current element path for an
251 ODR handle. This utility is useful in error handling or user-defined
254 Added ODR_PRINT utility odr_set_stream which is is a more generic
255 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
256 to a write function and pointer to close function. The close function - if
257 non-NULL - will be called during odr_destroy.
259 Fixed bug in CCL parser where truncation char was not removed from
260 right side when truncation=both was in effect.
262 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
265 --- 2.0.23 2004/08/11
267 Fix buffer overrun in CQL parser when dealing with proximity (%).
269 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
270 to UTF-8/UCS conversion is now only based on codetables.xml.
272 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
274 --- 2.0.22 2004/08/06
276 Add support for more "commit changes" in ZOOM (uses Extended Services).
278 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
281 Yet another small fix for configure of SSL.
283 --- 2.0.21 2004/05/14
285 Fix SSL libs for configure when --with-openssl=DIR is given.
287 --- 2.0.20 2004/05/10
289 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
291 SSL comstack now uses yaz.pem certificate file on server side
292 by default. Certificate filename can be configured by calling
293 comstack function cs_set_ssl_certificate_file before cs_bind is used.
295 Fix bug regarding multiple calls to ZOOM_connection_connect.
297 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
299 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
300 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
302 ZOOM now allows inspection of X509 peer certificate for verification.
303 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
305 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
306 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
307 as "modular" but it simplifies things.
309 Added cs_get_peer_certificate to that returns peer X509 PEM.
311 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
312 NULL if SSL is unavailable.
314 Documentation about MARC decoding tools.
316 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
318 --- 2.0.19 2004/03/30
320 Rename CHANGELOG to NEWS to follow GNU style packing.
322 Fix bug with missing initialization of member in init_diagnostics.
323 This bug affects threaded version of GFS server.
325 --- 2.0.18 2004/03/20
327 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
330 Ensure zlib.dll is packed with Windows install.
332 --- 2.0.17 2004/03/17
334 Fix encoding of xsd:string to use text instead of CDATA.
336 Fix endless loop in CQL parser with unbalanced ".
338 Use a more compact way to store MARC-8 conversion tables.
340 --- 2.0.16 2004/03/16 Debian only
342 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
345 Update CQL parser to use new CQL 1.1 modifiers for booleans and
350 --- 2.0.15 2004/03/01
352 Another fix for decoding of XML packed records.
354 --- 2.0.14 2004/02/25
356 Fixes for Chunked encoding. White space not ignored after length spec.
358 Update NS and use default NS for SRW diagnostic elements.
360 --- 2.0.13 2004/02/23
362 Implement ZOOM_resultset_cache_reset which resets record cache.
364 Implement ZOOM_resultset_sort which sorts a result set.
366 Implement chunked HTTP transfer.
368 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
370 --- 2.0.12 2004/02/16
372 Added member 'schema' to bend_explain_rr structure so that backend
373 can specify explain record identifier. Defaults to Zeerex 2.0.
375 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
377 --- 2.0.11 2004/02/16
379 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
382 Added init command for yaz-client which sends "extra" init request.
384 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
385 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
387 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
389 Make ZOOM error code for "invalid query".
391 Fixed compilation for SSL which wasn't properly enabled for all platforms.
393 --- 2.0.10 2004/02/05
395 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
398 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
400 Added option -p <file> to make Generic Frontend Server to write PID file.
402 Added option -D to put Generic Frontend Server in background on its own.
404 Make ZOOM C recognize option "password". If unset, "pass" is used
405 (for backwards compatibility).
407 Fixed a bug in Generic Frontend Server that could make it crash if a
408 client sets characterSetNegotation bit, but didn't pass negotiation stuff
411 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
412 Must be issued before open, in order to be in effect.
414 --- 2.0.9-6 2004/01/12 Debian/Windows
416 Make the SRU server more picky WRT unknown params, etc.
418 Bug fix: ZOOM scan response didn't return displayTerm - when present.
420 New YAZ client command, options, that sets Z39.50 options.
422 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
423 options from a string of tokens (one token for each option bit).
425 Update SRW diagnostic code messages.
427 --- 2.0.9-5 2004/01/07 Debian/Windows
429 Handle user defined stylesheet for SRW/SRU.
431 --- 2.0.9-4 2004/01/06 Debian/Windows
433 Fix bug in decoding of Content-Length.
435 --- 2.0.9-3 2004/01/06 Debian/Windows
437 Fix a bug with decoding of XML packed records.
439 --- 2.0.9-2 2004/01/05 Debian only
441 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
443 Fix bug in SRW/SRU diagnostics decoding.
447 Fixed bug in Generic Frontend Server which could drop records exceeding
448 preferred message size. Reported and fixed by Irina Dijour.
450 Fixed calculation of package size for structured records in Generic
451 Frontend Server. Reported and fixed by Irina Dijour.
453 Fixed namespace for SRW/SRU diagnostics.
455 Fixed SEGV in yaz-client that occured for HTTP connection errors.
459 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
460 this version is incompatible with version 1.0 and older YAZ SRW/SRU
463 CQL changes to reflect recent changes to the specification:
464 * Documentation talks about context sets instead of index sets.
465 * Documentation talks about indexes instead of qualifiers.
466 * The CQL-to-PQF transformer's configuration file now uses
467 "index.set.name = <attributes>" instead of the old form
468 "qualifier.set.name = <attributes>". (Both forms are still
469 understood but the latter is deprecated.)
470 * CQL terms with no explicit index specified are now interpreted as
471 cql.serverChoice instead of srw.serverChoice (which of course
472 behaves exactly the same.)
476 MARC conversion can now generate ISO2709 output in another
477 character set. yaz-marcdump uses this facility if you invoke it
480 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
481 functions from there can be used from C++.
485 Frontend server now transfers memory from decoded packages to stream
488 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
489 references to show up.
491 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
492 the ZOOM Abstract API. The older names for the same options are still
493 also supported for the benefit of old applications.
495 ZOOM-C supports "implementationId" and "implementationVersion" options
496 to go along with "implementationName". These allow the user code to
497 specify identification strings to be sent to servers.
498 Add OID for the new ExtLite attribute set.
500 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
501 as requested/supplid by Ere Maijala <ere@atp.fi>
503 For generic frontend server, reverse the order of
504 "toolkit-supplied / application-supplied" strings sent as implementationId,
505 Name and Version. Also, remove the spaces around the slash. This brings
506 the GFS in line with the behaviour of ZOOM-C on the client side.
508 Add function ZOOM_scanset_display_term.
510 yaz-client shows scan displayTerm if present.
512 Utility yaz-iconv is now installed by default along with the man page
515 Extend configure check for OpenSSL to use pkg-config where available (such
518 Incorporate patch by Morten Bogeskov which allows a Unix file socket
519 server to specify uid/gid/mask for socket using the format
520 unix:[user=uid,][group=gid,][umask=mask,]file=path
521 If file= is omitted the existing format is assumed, e.g.
523 in which case the mask is 0666 (rw for everybody).
525 Major restructure of YAZ source. All source in libyaz is in src directory.
526 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
527 util (utility programs such as ASN.1 compiler, yaz-marcdump).
529 Added man page for utility yaz-marcdump (used to be called marcdump).
530 yaz-marcdump is installed by 'make install'.
532 Fixed a memory leak in Generic Frontend Server that occurred when decoding
533 of incoming package failed.
535 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
537 Change prototype of odr_perror: add const to message string.
539 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
541 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
542 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
543 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
544 DNS lookup. There should not be any compatibility problems with this
545 assuming that blocking=1 or 0 is used.
547 Fix bad reference in UNIX comstack in function cs_addrstr.
549 Fix for compilation on AIX.
551 The generic front-end server (server/seshigh.c) now supports returning
552 Init diagnostics to the client in User-information-field, in
553 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
558 Allow any CQL relation (not just all,any,exact,scr).
560 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
561 that features the same UI.
563 Implemented command update0 in YAZ client which is equivalent to
564 update but uses old of Ext Update ASN.1.
566 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
567 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
568 Previously no OID was used for this info.
570 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
571 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
572 returns 'malformed search term' otherwise.
574 SortResponse member resultCount now set to NULL in sort handler of
577 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
580 Add three new utility functions for translating OIDs between various
581 formats -- symbolic name such as "Usmarc", minus-1-terminated int
582 arrays and dotted strings such as "1.2.840.10003.9.5.1":
583 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
584 char *oid_to_dotstring(const int *oid, char *oidbuf);
585 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
587 Reverted modifications for ES Update definition for z_IU0Update
588 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
589 is back to YAZ 2.0.2.
591 String value attributes for CCL parser.
593 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
594 which their FirstSearch server returns in Init responses, sometimes
595 carrying useful diagnostic information when Init fails. This has the
596 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
597 "z39.50/oclcui.asn", where its definition is somewhat different from
598 what OCLC document on their web-site, as required to interoperate with
601 Support for anonymous authentication in yaz-client. Use the command
604 * Fix the OID of the Index Data-local "admin" Extended Service from
605 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
606 the 1000, which indicates a locally-defined OID, was a mistake.
610 Fix CCL directive @case handling so that it affects string match for
611 both CCL keywords and qualifiers.
613 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
614 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
615 Decoder has been updated with ASN.1 changes as listed in
616 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
617 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
618 z_IUUpdate, remains unchanged.
620 ZOOM_record_get may now return a record in a specific character set.
621 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
622 "from" is the character set of record as returned by target. "to" is
623 the character set to be returned. If omitted, "to" is UTF-8.
625 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
627 New ODR utility, odr_getelement, which returns name of element for
628 which encoding/decoding failed.
630 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
631 in cases where a required element was omitted.
633 Bug fix: some MARC8 sequences were not converted.
635 New ZOOM option "step" which specifies number of records to be
636 retrieved in one chunk. Used in conjunction with "start" and "count".
638 SRW support for yaz-client. Use scheme http: to use it, e.g.
641 yaz-client no longer does (un)intelligent character set conversions
642 by default. Can be enabled with charset and marc_charset commands.
644 xmalloc trace fix for 64-bit systems such as DEC alpha.
646 Solaris 2.6 compile fix.
648 New function, cql_strerror() translates SRW error codes, as returned
649 by cql_transform_error(), into human-readable English strings. Used
650 in yaz-client diagnostics when appropriate.
652 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
653 converts it into a type-1 query which is sent to the server. This
654 makes CQL available for use with all Z-servers, as opposed to the tiny
655 minority that can handle CQL queries themselves.
659 New Debian package layout similar to the Redhat Package layout.
661 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
662 and search result respectively.
666 Redhat package is now several packages: libyaz (runtime libraries),
667 libyaz-devel (development and documentation, and yaz (utility programs).
668 Package spec file by Morten Bøgeskov.
670 New member 'schema' in struct bend_fetch_rr which the name of requested
671 schema (SRW/SRU) for record (or NULL if none was given). The fetch
672 handler MAY set this to reflect the schema of the returned record.
674 New member 'display_term' in struct scan_entry. GFS now sets member entries
675 and allocates scan entries to be filled by user scan handler. In previous
676 version, entries member was allocated by the scan handler. That still works,
677 but the GFS will ignore member display_term - assuming it was NOT set by
678 the handler. The fact that the GFS now allocates the entries both allows
679 for new members and makes a scan handler easier to write.
681 Fix CQL lex buffer overflow.
683 SRW/SRU recordPacking. For SRW default recordPacking is string. For
684 SRU default recordPacking is string.
686 SRU protocol support for frontend server.
688 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
690 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
692 Added scan for the ZOOM shell (zoomsh).
696 * String Identifers for Schemas (Amendment 5).
697 http://lcweb.loc.gov/z3950/agency/amend/am5.html
698 Old definition for schema
699 Odr_oid *schema; /* OPT */
704 Z_InternationalString *uri;
705 #define Z_Schema_oid 1
706 #define Z_Schema_uri 2
709 * resultCount parameter to Sort Response (Amendment 1).
710 http://lcweb.loc.gov/z3950/agency/amend/am1.html
712 Support for SRW 1.0 over HTTP. This is an optional feature and
713 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
716 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
717 on the same port. SRW SearchRetrieveRequests are mapped
718 to bend_init,bend_search,bend_fetch,bend_close.
720 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
722 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
723 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
725 ZOOM connections are SRW based if schem http is used for hostname
726 in connect, e.g. z = ZOOM_connection_new("http://myserver");
727 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
729 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
730 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
731 distance=n, order=true/false, relation=le, prox unit=word. If
732 n is omitted, distance 1 is used.
734 Fixed problem with C compiler include path in wrong order.
736 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
737 on Solaris. Patch from Ko van der Sloot.
739 New MARC decode API. All new functions operate on a yaz_marc_t
740 handle. The most important new functions are: yaz_marc_create,
741 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
742 decode and destroy respectively. Decoder can produce formats
743 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
744 include/yaz/marcdisp.h.
746 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
747 to UTF-8, UCS-32, wchar_t or Latin-1.
749 * Prototypes for yaz_iconv_-functions moved to separate header
750 include/yaz/yaz-iconv.h.
752 Make a few private functions 'static' in unix.c. This prevents
753 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
755 For ZOOM connection, the options targetImplementation{Id,Name,Version}
756 are set when Init Response is received.
758 New function ZOOM_connection_error_x similar to ZOOM_connection_error
759 but returns diagnostic set as well.
761 New function yaz_strerror which is a portable wrapper for
762 strerror/strerror_r/GetLastMessage.
764 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
765 is returned for MARC. If type is "oai", then OAI MARC is returned.
767 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
772 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
774 Fix bad race conditions on SIGTERM and terminate gracefully in
777 Move retrieval (data1) module to Zebra since nobody seems to be
780 Add GRS-1 render for ZOOM using same format as yaz-client.
784 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
786 Fix broken ESpec handling in data1 module.
788 SGML reader parses comments and makes them part of the data1 tree.
790 Added several type casts so that YAZ compiles as C++ code.
792 ZOOM didn't handle PDU encoding failures properly.
794 Added more Bib-1 diagnostics (approved extensions).
796 GNU configure: better check for iconv.
798 More portable use of accept, getpeername. Check for socklen_t. Use
799 int/size_t if socklen_t is not defined.
803 PQF parser rejects bad queries - including those with extra
804 characters in them. PQF parser used to silently ignore that.
805 Cleaner API for PQF added, which allows you to get detailed
806 error information for bad queries (see yaz/pquery.h).
808 Fixed bug in ZOOM_record_get for type "database".
810 Implemented mini iconv library supporting conversions between
811 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
813 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
817 Fixed ZOOM C record cache so that preferredRecordSyntax and
818 elementSetName is used to check for already fetched records.
822 Added three members in bend_initrequest structure to facilitate
823 character set negotiation.
825 Fixed a bug in frontend server that could cause indefinite
826 loops under rare conditions.
828 Revised character set utilities (charneg.h) so that encoding
829 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
831 For PQF, directive @term <type> sets term type for Scan/Search.
832 Here <type> is general, string, numeric, null. The term type
833 is inherited - just like @attr.
835 New call odr_set_charset that sets character set conversion for
836 international-strings on a ODR stream. Prototype is:
837 int odr_set_charset(ODR o, const char *to, const char *from);
838 The InternationalString is still represented as C string in YAZ
839 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
840 won't). On the protocol level, you can use any encoding.
842 Support for UNIX sockets in ZOOM.
844 Solaris recv sometimes returns errno == ENOENT. It is treated as
845 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
847 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
848 both client and server. Code by Morten Bøgeskov.
852 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
853 that they can be used directly from Visual Basic. You must recompile
854 your windows APP if you're using ZOOM.
856 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
857 Commands "lang" and "charset" sets language and character set respectively.
858 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
859 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
861 Attributes from multiple CCL fields may be OR'ed rather than merged
862 using directive "@field or". Fields are still merged by default -
863 equivalent to "@field merge".
865 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
868 Fixed bug in zget for parameter ExtendedServicesResponse.
874 Added PQF feature: '@attr type=value' may be written as '@type=value'.
876 Client displays USR.1:SearchResult-1 (hits per term).
878 Additional Search Info for search in Generic Frontend Server.
880 Fixed CCL parsing of "field=s".
882 WIN32 installer - using the excellent NSIS software from nullsoft.
884 Fixed CCL parsing of "field = - <number>".
886 Added function yaz_marc_decode that decodes MARC for line mode
887 display or XML (similar to that used by JZKit).
889 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
890 Z39.50. But ISO/ILL was, however.
892 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
893 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
895 http://lcweb.loc.gov/z3950/agency/amend/am2.html
896 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
900 New YAZ client features: Command completion and new commands:
901 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
902 Code provided by Jacob Poulsen.
904 New call oid_trav, that visits all registered OIDs via callback.
906 Function ZOOM_record_get now returns const char pointer rather than
907 void pointer. It saves a lot of type casts.
909 For YAZ client, command "auth" now allows you to set authentication
910 in IdPass style. It is enabled when three tokens are given - order
911 is user, group and password.
913 Fix memory leaks in MARC record handling for ZOOM.
915 New option for YAZ client, -k <kilobytes> that sets
916 maximum record size. Similar to -k option for generic frontend
917 server and yaz-ztest.
919 More fixes for scan. Non-zero stepSize handled. OID's fixes.
921 Prefix query parser reports "fail" when bad attribute set is given.
923 Fix in MARC decoder. Proximity logging. Fix for attribute set
924 in scan handler for server. Patches by Shigeru Ishida.
926 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
929 Configure option --with-openssl=<dir> now works when a directory is
930 specified. Patch provided by Morten Bøgeskov.
932 New option for YAZ client, -u <auth>, that sets authentication.
934 ZOOM fix: error information was sometimes "missing", since error
935 was cleared/reset too when it shouldn't.
937 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
941 Scan for ZOOM API. New object ZOOM_scanset. New functions
942 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
943 ZOOM_scanset_destroy.
945 New ZOOM function, ZOOM_connection_last_event, that returns type
946 of last event (such as "receive data", "send data", "apdu received",
949 New ZOOM option, schema, that specifies schema for retrieval.
951 New CCL feature. Qualifiers can be aliases for one or more
952 other qualifiers (if more than one is given, OR is used).
954 ZOOM uses named result sets if target supports it.
956 Two new YAZ client commands: . (dot, which sources a script of YAZ
957 client commands), and ! (to execute shell command.). Implemented
960 Working on Debian packages.
964 YAZ client enables named result sets only if target supports it.
966 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
968 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
969 with key="host" to get same result.
971 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
972 Function Z3950_resultset_record(s) returns references to records
973 "owned" by resultset. To become owner use Z3950_record_clone.
975 Function z_ext_record handles Extended Services. Thanks to
980 CCL Parser fix: ignore token comma when dealing with and-lists.
982 Documentation updates for COMSTACK.
984 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
985 Changed prototype Z3950_records. For some functions, int parameters
986 were changed to size_t.
988 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
991 New MARC decode/display function, marc_display_exl, which properly rejects
992 non-ISO2709 records. YAZ client uses it.
996 Fix bug: local attribute set wasn't set correctly in PQF strings.
1000 * Old Z39.50 codecs no longer supported.
1002 Added ZOOM C binding. See http://zoom.z3950.org/
1004 Renamed states for COMSTACKs to avoid confusion with events.
1006 Implemented cs_look and proper cs_rcvconnect.
1008 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1010 Configure detects POSIX threads on OpenBSD.
1012 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1013 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1015 When error is returned from present handler, non-surrogate diagnostic
1016 is returned in present response (and fetch handler is no longer called).
1018 * Minor adjustments to pquery parser (PQF). Token characters may be
1019 escaped by using backslash (C-style).
1021 PQF parser allows string attribute values to be specified. For @attr,
1022 non-numeric characters after the equal-sign are treated as strings
1023 (e.g. @attr 9=title).
1025 CCL trunction character may be defined (@truncation in file)
1027 * function zget_ExtendedServicesRequest sets waitAction to
1028 waitIfPossible (was wait).
1030 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1033 CCL operator names may be set in field definition files (CCL_bibset).
1034 See ccl/bib1 for an example.
1036 Fixes in ASN.1 compiler for C++ compatibility.
1038 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1039 and "op_or" to avoid conflict with C++.
1041 Fixed problem with GNU readline detection on Redhat 7.0.
1043 Added step-size for Scan backend handler.
1045 Fixed bug that made the frontend server crash when no attribute
1046 set was specified for scan.
1048 Front-end server automatically switches to original working directory
1049 when installed as an NT service. Previously -w had to be specified to
1052 Added extended attributes for retrieval module (data1), so that data1
1053 records carry d1_readXML/SGML attributes. d1_read also supports
1054 null-data rules ( <tag/>)
1056 On UNIX when POSIX threads are available, a separate library libyazthread
1057 is created. Programmers should link with that library and the yaz library
1058 when using threads. The reason for the split was that some applications
1059 on Linux, such as Apache, doesn't work well when using shared objects that
1062 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1063 (or any frontend server) in SSL mode by specifying ssl: followed by
1064 address. Only tested on UNIX.
1066 Added feature for CCL module. Virtual structure s=al or s=ol generates
1067 and-list and or-list respectively instead of phrase search.
1071 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1072 log_mask_str. This was done to avoid name conflicts with other libraries
1073 (such as other PHP extensions).
1075 Added raw OID member for preferred record syntax (request_format_raw)
1076 and returned record syntax (output_format_raw) for backend fetch method.
1078 Config file yaz-config now accepts options so that it returns specific
1079 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1081 Shared library support for UNIX using GNU libtool.
1083 * Modified backend interface. Request/Response struct's replaced by
1084 one read/write C struct. For example bend_fetchrequest and
1085 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1086 Every handler - even search has to be registered in bend_init
1087 handler. This means that the YAZ library no longer refers to
1088 external functions and it makes it possible to make the whole
1089 thing a single DLL/SO.
1091 Added Segment handler for backend server.
1093 Added Zmbol/Zebra administrative functions to YAZ client.
1095 Threaded frontend server on UNIX (when POSIX Threads are available).
1096 Starting the server with option -T enables multi-threading.
1100 Added configure option --enable-comp/disable-comp to control use
1101 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1102 located in sub directory asn.
1104 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1105 in ${exec_prefix}/bin along with the other programs yaz-client and
1108 GNU automake used to maintain makefiles.
1110 Added several OID's.
1112 Changed retrieval module so that we can load records with no abstract
1113 syntax defined. Tagpaths in these records are fully composed of string
1116 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1120 On UNIX, the generated makefile now supports a proper 'make install'.
1121 The prefix can be set via GNU configure to set the install location
1122 (default is /usr/local).
1124 * YAZ programs client and ztest were renamed to yaz-client and
1125 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1126 locations, such as /usr/bin,/usr/local/bin,etc.
1128 * YAZ Header files were moved from include to include/yaz. YAZ Header
1129 files are referred to as include <yaz/log.h> rather than <log.h>.
1130 The YAZ include path (-I ..) is therefore the same as before. Programmers
1131 should update their #include statements or use -Ipath/include/yaz
1132 instead. The main motivation for doing this change is that YAZ header files
1133 can be installed in "standard" locations /usr/include,/usr/local/include
1134 without introducing conflicts, since ALL YAZ header files are stored
1135 in subdirectory yaz (under /usr/include for example).
1137 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1138 rather than project/workspace files. We switched because project files
1139 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1142 Changed name of logging function, logf, to yaz_log, to prevent name
1143 clash with some math-log functions. The YAZ header log.h defines logf
1144 to yaz_log (#define) so there should be no incompatibilities by this
1147 Added bend_start/bend_stop handlers for server. These handler are
1148 called on start/stop of server. For windows they are called whenever
1149 a service is started/stopped.
1151 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1152 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1153 in util/yc.tcl. The auto-generated C code structures are, in a few
1154 cases, incompatible with the old decoders. There are differences in the
1155 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1156 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1157 The preprocessor variable ASN_COMPILED is defined when the compiled
1158 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1159 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1160 wish to use the old encoders/decoders you can specify --disable-yc
1163 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1164 version so that it supports both new - and old version of DB Update
1166 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1167 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1168 change. The name parameter can be set to 0 in which no name is specified
1169 for the construction. The macros odr_implicit and odr_explicit sets name
1170 parameter to zero for the construction involved. New macros
1171 odr_implicit_tag and odr_explicit_tag are similar to the others,
1172 except that a name parameter is added. For programmers' that don't use
1173 ODR they probably only need to change the call to z_APDU and z_External.
1175 Added access control facility by interfacing the TCP wrapper library.
1176 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1177 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1178 name of the daemon and enables the access control as specified in
1179 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1181 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1182 den Dool <H.M.vdnDool@kub.nl>.
1184 Added reference ID parameter to most functions in server API - refer
1185 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1187 Changed name of ccl library to libccl.a (was ccl.a).
1189 Fixed bug in decoder for Explain (Category TargetInfo).
1191 Added support for GNU readline in client. Thanks to Jacob Poulsen
1192 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1194 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1195 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1196 IMPLEMENTATION! This change was made to the development version before
1197 the ZIG decided to retract the amendment. If any users MUST be
1198 compatible with the original Update definition, PLEASE CONTACT US, and
1199 we will include a separate definition corresponding to the old Update
1200 ES. Note that because of the change to the ASN.1 of the
1201 TaskPackageRecordStructure we cannot define a single structure that
1202 will support both versions.
1204 * Added const modifier to buffer parameter for some ODR/BER encoding
1205 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1206 completeWAIS, odr_dumpBER.
1208 Fixed bug in client.c which caused a crash when a scanResponse didn't
1209 contain positionOfTerm.
1211 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1212 * will cause an error in a client if a non-YAZ target sends both a
1213 * list of Scan entries and non-surrogate diagnostics.
1215 Retrieval module enhancements. Tag sets may be typed in the reference
1216 to it. From the .abs-file the "tagset" directive takes a third optional
1217 integer type for the tag set referenced. From a .tag-file the "include"
1218 directive takes a third optional type as well. The old "type" directive
1219 in the tag set itself is still recognized but acts as the default type
1222 Backend interface change. Individual Scan terms returned from bend_scan
1223 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1224 in include/backend.h.
1226 Retrieval module enhancements. Multiple tag sets and attribute sets may
1227 be specified in abstract syntax specs. Revised the error/warning for
1228 logging messages reported by the retrieval module when reading the
1231 Object Identifier system (oid_..) changed. The API is backwards
1232 compatible but the oid-routines now allocates new OID's when needed.
1233 Raw OID's may be specified in oid_getvalbyname.
1235 YAZ now uses GNU configure to generate Makefile(s).
1237 * Minor changes in some of the member names of DeleteResultSetRequest and
1238 DeleteResultSetResponse. See include/proto.h.
1240 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1241 and added member 'languages' in TargetInfo (which was missing).
1243 Changed the way attribute sets are handled in the retrieval
1244 module. These are now cached, just like the abstract syntaxes
1247 Changed YAZ so that it links with compiled ASN.1.
1249 Added Explain-schema definitions and mapping routines. The following
1250 Explain categories have been implemented: AttributeDetails,
1251 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1253 Fixed minor bug in Windows version of Server Library.
1255 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1257 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1259 Added EXTERNAL: UNIverse Resource Report (non-standard).
1261 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1262 ENUMERATED and SET OF.
1264 * Added 'const' to some of the char pointer arguments for the
1265 functions, data1_read_node, data1_getelementbytagname,
1266 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1269 Fixed bug in data1_insert_taggeddata - the last_child member of
1270 parent wasn't initialised.
1272 * Changed data1_read_record and data1_read_node so that the supplied
1273 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1274 doesn't refer to any parts of the "SGML"-buffer.
1276 Fixed bug in server library (Windows version of statserv_remove).
1278 * Changed code so that it compiles as C++. The type definition
1279 of Odr_fun which is a member of Odr_arm was changed. The result is,
1280 that an explicit typecast is needed for the fun pointer when
1281 using Odr_arm - as in:
1282 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1284 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1286 Implemented the new structured date and time definition as approved
1287 by the ZIG. Added schemaId element to the specificTag in Espec-1
1288 (also approved at the last ZIG). Thanks to RVDM.
1290 Added some Object identifiers (RVDM).
1292 Changed the Update Extended Service (RVDM).
1294 Added command "refid" to client which specifies referenceId for
1295 the following requests.
1297 Implemented extended service handling for server. See ztest.c
1298 for an example as well as backend.h. New handlers are registerd
1299 in the Init handler.
1301 * Changed interface for sort in server.
1303 Added new members to statserv_options_block. It allows a server
1304 to read options from another source than just the command line. Thanks
1305 to Charles Woodfield.
1307 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1308 renamed to zboolean. Some C++ compilers complained about the name.
1310 Minor changes to gils.abs. Added index 's' (sort) on title
1311 and date/time-last-modified.
1313 --- 1.4pl2 1998/1/30
1315 Fixed bug in server library regarding inetd mode (-i). This bug
1316 was introduced by release 1.4.
1318 --- 1.4pl1 1998/1/29
1320 Added sort facility in client and backend server interface.
1322 Fixed problem with dependencies in Makefile(s).
1324 Fixed bugs for encoders/decoders of extended services and
1327 Implemented sub-tree feature for schemas. Sub-trees are
1328 referenced in *.abs-files. See explain.abs for an example
1329 of the use of this feature.
1331 Modified bib1.att; local attributes for ANY didn't include
1332 ANY itself (only affects use of the retrieval module).
1334 Fixed bug in plain SGML reader in function data1_read_node:
1335 tags with prefix "var" was incorrectly interpreted as variants.
1337 Added feature "sub-schemas" to enable references to - and definitions
1338 of - group of elements.
1340 * Removed member parent from type data1_element (in data1.h).
1342 Implemented function odr_nullval() that returns the value of
1345 * Removed member num_children from data1_node (in data1.h).
1347 Made NT service interface part of the server library. The
1348 function statserv_main uses the NT service when required and
1349 calls the statserv_start / statserv_close routines.
1351 Routine zget_SearchRequest and zget_PresentRequest fills
1352 resultSetName/Id member with "default" instead of "Default".
1354 Fixed memory leak in server. Request queue member wasn't freed.
1356 Fixed nmem_exit so that memory is freed.
1360 Revised the CCL parser utility to be thread safe.
1362 Added function, oid_ent_to_oid, to replace the function
1363 oid_getoidbyent, which is not thread safe.
1365 * Added nmem_init and nmem_exit to initialize and release
1366 NMEM resources. Function nmem_init should be called once in the
1367 initial thread before NMEM/ODR is used. statserv.c and client.c
1368 have been changed accordingly. The change was necessary to make
1369 NMEM thread safe. The NMEM memory pool is shared amongst threads
1370 in a process. Unix-based applications will still work fine without
1373 Added NT Services interface for the the Z39.50 (statserv) Server.
1374 Refer to the ztest.c source on the usage.
1376 Windows 95/NT port using MSVC5.0. Project files are included in the
1379 * Defined new 'global' handle for the retrieval (data1) system. The
1380 new handled, data1_handle, describes the state of the data1 system.
1381 This handle is passed as first argument to virtually all
1382 data1 related routines. The functions data1_create and data1_destroy
1383 creates and destroys a data1 handle respectively.
1385 Added ODR encode stream member to all backend request structures
1386 init, search, scan etc. This stream should be used to allocate all
1387 memory used for the response when thread safe operation is needed.
1389 Changed the comstack utility, cs_addstr, to be thread safe. The
1390 returned hostname string returned by the function is now part the
1393 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1394 function. The cs_straddr takes a COMSTACK handle as argument, so this
1395 function must be used after cs_create and before bind/connect.
1396 This function is thread safe.
1398 Moved test server to 'ztest' directory - generic server code still
1399 in 'server' directory.
1401 Made prefix query (pquery.c) utility thread safe.
1403 Added new function modifier YAZ_EXPORT to 'export' public DLL
1404 functions when using windows (see include/yconfig.h).
1406 Added definitions to the OID database (util/oid.c) (RVDM).
1408 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1410 Added call to ccl_rpn_delete in client program.
1412 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1413 release of RPN structure.
1415 Added support for C++, headers uses extern "C" for public definitions.
1416 With input from RVDM.
1418 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1419 Thanks to Ronald van der Meer (RVDM).
1421 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1423 Added support for private extensions to the OID database
1424 (oid_setprivateoids()). Thanks to RVDM.
1426 Added optional, physical ANY (key replication)
1428 Fixed null-reference problem in GRS-1 output filter.
1430 Proximity operator added to Prefix Query Format (PQF).
1432 In test client command "base" accepts multiple databases.
1434 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1438 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1440 Smallish bug-fixes in the new encoders/decoders (explain).
1442 Bug fixed in DeleteRequest.
1444 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1446 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1448 Added SOIF syntax (using private OID for now) to retrieval module and client.
1450 Added Update extended service.
1452 Added SearchResult-1 additional info structure.
1454 Added optional CCL (ISO8777) interpreter as separate module. Available
1457 --- 1.2 1996/6/10 (1st anniversary release)
1459 Added Summary record syntax. Lightly tested.
1461 Added OPAC record syntax. Untested.
1463 Added ResourceReport service encoders/decoders. Untested.
1465 Fixed bug in z_Unit - wrong tagging on unitSystem.
1467 Fixed bug in the DiagRecs decoder.
1469 Added options for max PDU size and session timeout to frontend-server.
1471 Added documentation of query-language parsers and other supporting utilities.
1473 [frontend-server] Added Attribute set to the bend_scanrequest API.
1475 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1476 surrogate diagnostics were generated.
1478 [retrieval] Allow multiple local values for attribute.
1480 [retrieval] Allow multiple attributes per element in .abs files. index type.
1482 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1484 --- 1.1pl2 1996/4/10
1486 Minor changes, mostly specific to Zebra's requirements (retrieval)
1490 Repaired bug in frontend server when running multiple listening
1491 endpoints in dynamic mode.
1493 z_External() now won't break if a known, ASN.1 value comes encapsulated
1494 in an octet-string. The value will pass through unmodified in an Odr_oct.
1496 Added a bit of code to the demo client to decode & display
1497 ASN.1-structured records represented in the octet-aligned branch of
1498 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1500 Added z_ext_getentbyref() to the ASN module. Doc updated.
1502 * Completed the SCAN definition in the ASN module. This may break SCAN
1503 code based on older YAZ-versions at compile-time. The fix is easy -
1506 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1507 under the SCAN definition. Remember to initialize this, server-people.
1509 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1510 that this does not extend to ODR and ASN.
1512 Comstack allows insertion of established socket (primarily for
1513 inetd-operation of servers). Doc updated.
1515 Front-end server can now start from the inetd in TCP mode. Doc
1518 --- 1.0pl4 1996/1/24
1522 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1523 the rank and record number.
1525 Adjustments to the frontend server.
1527 Fixed diagnostic BER dumper. It ignored the file argument.
1531 Various changes to retrieval module.
1533 Changed the union discriminators of the protocol files from enums to
1534 ints paired with #defines.
1536 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1539 *Changed operator in the RPN structure to 'roperator', again to avoid a
1542 Fixed problems in Explain decoders/encoders.
1544 --- 1.0pl2 1995/12/6
1546 Memory bug in log module fixed.
1548 --- 1.0pl1 1995/12/5
1550 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1552 Bug in Explain DatabaseInfo module fixed.
1554 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1558 The shift to v1.0 signals that we now consider the *core* functionality
1559 of YAZ reasonably stable (the core being more or less equivalent to
1560 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1561 tested (Explain not at all - though that will happen soonish).
1563 Minor changes to code to support Windows port.
1565 Various minor changes after we're getting to use GRS-1 & co. more.
1567 Added Espec-1 format.
1569 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1570 of the protocol and it cannot be selected when encoding (maps into 'string'
1571 when decoding). Needed to talk to some servers.
1573 Demo client can request simple element set names.
1575 Added Diagnostic Format encoders/decoders.
1577 Added simple Close handling to frontend server (no hooks for resource
1578 reporting yet), and demonstration client.
1580 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1582 --- 1.0b3 1995/08/24
1584 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1585 handled incorrectly when records were requested in the searchResponse. This
1586 will only affect you if you use the frontend-server.
1588 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1589 Test-client will ask for and print GRS1. Ztest will return dummy records
1592 Added Explain encoders/decoders to the service-level API. Untested.
1594 Added Extended Services: Item Order encoders and decoders to the Service-
1595 level API. Untested. We could use a recent copy of the pertinent bits
1596 of the ILL protocol to add those bits.
1598 Added diagnostic format 1 encoders/decoders to the service-level API.
1601 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1602 odr_cons.c, which causes a more correct output.
1604 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1605 was always set to 0 when no records were requested in the searchRequest.
1607 * Added better external-handling. This shouldn't harm old code that
1608 *encodes* externals. It can break code that looks for a
1609 'single-ASN1-type' representation, since those types that are known
1610 are now decoded immediately. Look at the SUTRS sample code in
1611 seshigh.c and client.c. Documentation updated.
1613 Handling of structured records in bend_fetchresponse. Length -1 marks
1614 structured record, type is deduced from format field.
1616 --- 1.0b2 1995/06/27
1617 Fairly quick maintenance release to add SUTRS support.
1619 Fixed handling of SUTRS records in the demonstration client.
1621 * Added format field to the bend_fetchrequest and bend_fetchresponce
1622 structures of the backend API (frontend server). When the record is
1623 returned, the value of the format field is mapped to an OID. The
1624 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1625 of the record. The special value VAL_NONE in the bend_request means
1626 that no specific format was requested by the client. Documentation
1627 updated accordingly. Test server (ztest) will return a fixed dummy
1628 SUTRS record if your client requests SUTRS.
1630 Documentation updated accordingly.
1632 You can now set external libraries and RANLIB support in the top-level
1636 First public release.
