1 Possible compatibility problems with earlier versions marked with '*'.
5 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
6 MARC output rather than returning "new" buffer.
10 Added support for SRW sort in Generic Frontend Server. Patch
11 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
12 sortKeys - or NULL if none is provided.
14 Fixed bug #307: It was impossible to specify indefinite/no timeout
15 for ZOOM_event. Special timeout value -1 now means indefinite timeout
18 Added support for multiple languages and charsets to be specified in
19 ZOOM. Each charset/language is separated by a blank. If negotiation is
20 in effect in init-response, Option
21 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
22 Code based on patch by Vasiliy Osadchuk.
24 Fixed bug #306: infinite recursion that occurred when calling
25 yaz_log_level_init as the first call (before other log level or
28 Fixed bug in scan handling in front end server: if preferred-Position-In-
29 Response was non-present, a NULL pointer referece was performed.
33 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
34 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
35 now defined for all those error codes. So instead of putting 109 in
36 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
37 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
39 Modified the yaz-marcdump utility to skip garbage bytes between MARC
42 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
44 Program yaz-client now exits and produces an error message if multiple
45 Z39.50 servers are specified on the command line (none or one allowed
48 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
53 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
55 Fixed bug #272: Preserve spacing for CCL terms.
59 Added support for virtual hosts and multiple backend servers for
60 the YAZ frontend server. The configution is XML based and
61 support specificition of CQL to RPN mappings and explain information.
62 See section "Virtual Hosts" in the YAZ manual.
64 Extended OPAC display utility. OPAC display utility renders
65 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
66 to supplement yaz_marc_decode_wrbuf.
68 Fixed a bug in MARC decoder that could caused it to crash for some
69 invalid MARC records. More diagnostics and warnings where added in
70 XML output (warnings, etc are stored in comments).
74 Fixes for UNIX domain sockets. Bug #261.
76 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
78 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
79 Added yaz_marc_subfield_str which defines subfield lead string which is
80 used in YAZ_MARC_LINE format. Default string is blank+$. Added
81 yaz_marc_endline_str which defines end of fields string used in
82 YAZ_MARC_LINE format. Default string is newline.
84 Experimental support for MarcXChange. This format can be produced
85 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
86 http://www.bs.dk/standards/MarcXchange.xsd
88 Added yaz-client commands scansize that sets maximum number of
89 entries to be returned by scan.
93 Added support for SRW scan in yaz-client and Generic Frontend Server.
95 * Added whereInList member to SRW Scan Term.
97 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
99 Fixed NMEM system to return aligned blocks on the smallest boundaries
100 that are suitably aligned for all possible types on the particular
101 architecture YAZ is being built for.
103 --- 2.0.30 2005/01/04
105 Fixed numerious warnings that was issued with newer versions of GCC.
107 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
108 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
111 Make YAZ Generic Frontend Server slightly faster.
113 Enhance (and reduce) logging for Generic Frontend Server.
115 Revert YAZ log system so that it flushes every write operation
116 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
118 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
119 instead of LOG_, due to name clash with syslog(3). LOG_ are still
120 present. New applications should define YAZ_USE_NEW_LOG=1 - this
121 will effectively disable old definitions.
123 --- 2.0.28 2004/11/09
125 Added yaz_log_time_format which specifies log format using
128 Added yaz_log_module_level which returns mask for a module. Value
129 is non-zero mask a if module is enabled; zero if disabled.
131 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
132 in include/yaz/cql.h.
134 Fixed bug #176: Dont throw diagnostics on empty SRU args.
136 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
138 Fixed bug #172: RPM builds does not enable SSL.
140 Doxyfile.in part of dist. Doxyfile generated by configure.
142 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
143 are given and the corresponding component does not exist.
145 Extend CCL documentation in YAZ reference. Describe r=r.
147 --- 2.0.26 2004/10/01
149 Fixed MARC->MARCXML conversion to properly deal with
150 fields, subfields, indicators having non-ASCII characters.
152 Fixed MARC->MARCXML conversion so that ASCII control characters
153 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
156 Added YAZ GFS support for conversion from Z39.50 surrogate
157 diagnostics to SRW surrogate diagnostics.
159 Bug fix: YAZ GFS did not return schema in explainResponse.
161 --- 2.0.25 2004/09/30
163 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
164 now converts recordSchema to elementSetName as well as schema URI.
166 Fixed bug in COMSTACK that prevented HTTP request packages from being
169 --- 2.0.24 2004/09/29
171 Added CCL facility r=r "range" which is similar to r=o "ordered" but
172 does not require white-space before and after the dash in a range, e.g.
173 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
176 Fixed a few AC_TRY_LINK configure tests that did not operate properly
177 due to new GCC removing "redundant" code.
179 Added yaz-client commands scanpos and scanstep that sets preferred
180 position and step-size for scan.
182 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
184 Added CCL utility ccl_qual_buf which parses one or more CCL
185 spec lines in a buffer.
187 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
188 of name and value - ignoring empty lines and comments.
190 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
192 Added odr_get_element_path which returns current element path for an
193 ODR handle. This utility is useful in error handling or user-defined
196 Added ODR_PRINT utility odr_set_stream which is is a more generic
197 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
198 to a write function and pointer to close function. The close function - if
199 non-NULL - will be called during odr_destroy.
201 Fixed bug in CCL parser where truncation char was not removed from
202 right side when truncation=both was in effect.
204 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
207 --- 2.0.23 2004/08/11
209 Fix buffer overrun in CQL parser when dealing with proximity (%).
211 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
212 to UTF-8/UCS conversion is now only based on codetables.xml.
214 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
216 --- 2.0.22 2004/08/06
218 Add support for more "commit changes" in ZOOM (uses Extended Services).
220 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
223 Yet another small fix for configure of SSL.
225 --- 2.0.21 2004/05/14
227 Fix SSL libs for configure when --with-openssl=DIR is given.
229 --- 2.0.20 2004/05/10
231 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
233 SSL comstack now uses yaz.pem certificate file on server side
234 by default. Certificate filename can be configured by calling
235 comstack function cs_set_ssl_certificate_file before cs_bind is used.
237 Fix bug regarding multiple calls to ZOOM_connection_connect.
239 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
241 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
242 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
244 ZOOM now allows inspection of X509 peer certificate for verification.
245 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
247 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
248 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
249 as "modular" but it simplifies things.
251 Added cs_get_peer_certificate to that returns peer X509 PEM.
253 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
254 NULL if SSL is unavailable.
256 Documentation about MARC decoding tools.
258 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
260 --- 2.0.19 2004/03/30
262 Rename CHANGELOG to NEWS to follow GNU style packing.
264 Fix bug with missing initialization of member in init_diagnostics.
265 This bug affects threaded version of GFS server.
267 --- 2.0.18 2004/03/20
269 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
272 Ensure zlib.dll is packed with Windows install.
274 --- 2.0.17 2004/03/17
276 Fix encoding of xsd:string to use text instead of CDATA.
278 Fix endless loop in CQL parser with unbalanced ".
280 Use a more compact way to store MARC-8 conversion tables.
282 --- 2.0.16 2004/03/16 Debian only
284 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
287 Update CQL parser to use new CQL 1.1 modifiers for booleans and
292 --- 2.0.15 2004/03/01
294 Another fix for decoding of XML packed records.
296 --- 2.0.14 2004/02/25
298 Fixes for Chunked encoding. White space not ignored after length spec.
300 Update NS and use default NS for SRW diagnostic elements.
302 --- 2.0.13 2004/02/23
304 Implement ZOOM_resultset_cache_reset which resets record cache.
306 Implement ZOOM_resultset_sort which sorts a result set.
308 Implement chunked HTTP transfer.
310 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
312 --- 2.0.12 2004/02/16
314 Added member 'schema' to bend_explain_rr structure so that backend
315 can specify explain record identifier. Defaults to Zeerex 2.0.
317 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
319 --- 2.0.11 2004/02/16
321 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
324 Added init command for yaz-client which sends "extra" init request.
326 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
327 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
329 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
331 Make ZOOM error code for "invalid query".
333 Fixed compilation for SSL which wasn't properly enabled for all platforms.
335 --- 2.0.10 2004/02/05
337 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
340 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
342 Added option -p <file> to make Generic Frontend Server to write PID file.
344 Added option -D to put Generic Frontend Server in background on its own.
346 Make ZOOM C recognize option "password". If unset, "pass" is used
347 (for backwards compatibility).
349 Fixed a bug in Generic Frontend Server that could make it crash if a
350 client sets characterSetNegotation bit, but didn't pass negotiation stuff
353 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
354 Must be issued before open, in order to be in effect.
356 --- 2.0.9-6 2004/01/12 Debian/Windows
358 Make the SRU server more picky WRT unknown params, etc.
360 Bug fix: ZOOM scan response didn't return displayTerm - when present.
362 New YAZ client command, options, that sets Z39.50 options.
364 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
365 options from a string of tokens (one token for each option bit).
367 Update SRW diagnostic code messages.
369 --- 2.0.9-5 2004/01/07 Debian/Windows
371 Handle user defined stylesheet for SRW/SRU.
373 --- 2.0.9-4 2004/01/06 Debian/Windows
375 Fix bug in decoding of Content-Length.
377 --- 2.0.9-3 2004/01/06 Debian/Windows
379 Fix a bug with decoding of XML packed records.
381 --- 2.0.9-2 2004/01/05 Debian only
383 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
385 Fix bug in SRW/SRU diagnostics decoding.
389 Fixed bug in Generic Frontend Server which could drop records exceeding
390 preferred message size. Reported and fixed by Irina Dijour.
392 Fixed calculation of package size for structured records in Generic
393 Frontend Server. Reported and fixed by Irina Dijour.
395 Fixed namespace for SRW/SRU diagnostics.
397 Fixed SEGV in yaz-client that occured for HTTP connection errors.
401 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
402 this version is incompatible with version 1.0 and older YAZ SRW/SRU
405 CQL changes to reflect recent changes to the specification:
406 * Documentation talks about context sets instead of index sets.
407 * Documentation talks about indexes instead of qualifiers.
408 * The CQL-to-PQF transformer's configuration file now uses
409 "index.set.name = <attributes>" instead of the old form
410 "qualifier.set.name = <attributes>". (Both forms are still
411 understood but the latter is deprecated.)
412 * CQL terms with no explicit index specified are now interpreted as
413 cql.serverChoice instead of srw.serverChoice (which of course
414 behaves exactly the same.)
418 MARC conversion can now generate ISO2709 output in another
419 character set. yaz-marcdump uses this facility if you invoke it
422 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
423 functions from there can be used from C++.
427 Frontend server now transfers memory from decoded packages to stream
430 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
431 references to show up.
433 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
434 the ZOOM Abstract API. The older names for the same options are still
435 also supported for the benefit of old applications.
437 ZOOM-C supports "implementationId" and "implementationVersion" options
438 to go along with "implementationName". These allow the user code to
439 specify identification strings to be sent to servers.
440 Add OID for the new ExtLite attribute set.
442 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
443 as requested/supplid by Ere Maijala <ere@atp.fi>
445 For generic frontend server, reverse the order of
446 "toolkit-supplied / application-supplied" strings sent as implementationId,
447 Name and Version. Also, remove the spaces around the slash. This brings
448 the GFS in line with the behaviour of ZOOM-C on the client side.
450 Add function ZOOM_scanset_display_term.
452 yaz-client shows scan displayTerm if present.
454 Utility yaz-iconv is now installed by default along with the man page
457 Extend configure check for OpenSSL to use pkg-config where available (such
460 Incorporate patch by Morten Bogeskov which allows a Unix file socket
461 server to specify uid/gid/mask for socket using the format
462 unix:[user=uid,][group=gid,][umask=mask,]file=path
463 If file= is omitted the existing format is assumed, e.g.
465 in which case the mask is 0666 (rw for everybody).
467 Major restructure of YAZ source. All source in libyaz is in src directory.
468 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
469 util (utility programs such as ASN.1 compiler, yaz-marcdump).
471 Added man page for utility yaz-marcdump (used to be called marcdump).
472 yaz-marcdump is installed by 'make install'.
474 Fixed a memory leak in Generic Frontend Server that occurred when decoding
475 of incoming package failed.
477 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
479 Change prototype of odr_perror: add const to message string.
481 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
483 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
484 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
485 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
486 DNS lookup. There should not be any compatibility problems with this
487 assuming that blocking=1 or 0 is used.
489 Fix bad reference in UNIX comstack in function cs_addrstr.
491 Fix for compilation on AIX.
493 The generic front-end server (server/seshigh.c) now supports returning
494 Init diagnostics to the client in User-information-field, in
495 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
500 Allow any CQL relation (not just all,any,exact,scr).
502 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
503 that features the same UI.
505 Implemented command update0 in YAZ client which is equivalent to
506 update but uses old of Ext Update ASN.1.
508 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
509 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
510 Previously no OID was used for this info.
512 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
513 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
514 returns 'malformed search term' otherwise.
516 SortResponse member resultCount now set to NULL in sort handler of
519 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
522 Add three new utility functions for translating OIDs between various
523 formats -- symbolic name such as "Usmarc", minus-1-terminated int
524 arrays and dotted strings such as "1.2.840.10003.9.5.1":
525 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
526 char *oid_to_dotstring(const int *oid, char *oidbuf);
527 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
529 Reverted modifications for ES Update definition for z_IU0Update
530 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
531 is back to YAZ 2.0.2.
533 String value attributes for CCL parser.
535 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
536 which their FirstSearch server returns in Init responses, sometimes
537 carrying useful diagnostic information when Init fails. This has the
538 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
539 "z39.50/oclcui.asn", where its definition is somewhat different from
540 what OCLC document on their web-site, as required to interoperate with
543 Support for anonymous authentication in yaz-client. Use the command
546 * Fix the OID of the Index Data-local "admin" Extended Service from
547 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
548 the 1000, which indicates a locally-defined OID, was a mistake.
552 Fix CCL directive @case handling so that it affects string match for
553 both CCL keywords and qualifiers.
555 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
556 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
557 Decoder has been updated with ASN.1 changes as listed in
558 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
559 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
560 z_IUUpdate, remains unchanged.
562 ZOOM_record_get may now return a record in a specific character set.
563 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
564 "from" is the character set of record as returned by target. "to" is
565 the character set to be returned. If omitted, "to" is UTF-8.
567 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
569 New ODR utility, odr_getelement, which returns name of element for
570 which encoding/decoding failed.
572 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
573 in cases where a required element was omitted.
575 Bug fix: some MARC8 sequences were not converted.
577 New ZOOM option "step" which specifies number of records to be
578 retrieved in one chunk. Used in conjunction with "start" and "count".
580 SRW support for yaz-client. Use scheme http: to use it, e.g.
583 yaz-client no longer does (un)intelligent character set conversions
584 by default. Can be enabled with charset and marc_charset commands.
586 xmalloc trace fix for 64-bit systems such as DEC alpha.
588 Solaris 2.6 compile fix.
590 New function, cql_strerror() translates SRW error codes, as returned
591 by cql_transform_error(), into human-readable English strings. Used
592 in yaz-client diagnostics when appropriate.
594 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
595 converts it into a type-1 query which is sent to the server. This
596 makes CQL available for use with all Z-servers, as opposed to the tiny
597 minority that can handle CQL queries themselves.
601 New Debian package layout similar to the Redhat Package layout.
603 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
604 and search result respectively.
608 Redhat package is now several packages: libyaz (runtime libraries),
609 libyaz-devel (development and documentation, and yaz (utility programs).
610 Package spec file by Morten Bøgeskov.
612 New member 'schema' in struct bend_fetch_rr which the name of requested
613 schema (SRW/SRU) for record (or NULL if none was given). The fetch
614 handler MAY set this to reflect the schema of the returned record.
616 New member 'display_term' in struct scan_entry. GFS now sets member entries
617 and allocates scan entries to be filled by user scan handler. In previous
618 version, entries member was allocated by the scan handler. That still works,
619 but the GFS will ignore member display_term - assuming it was NOT set by
620 the handler. The fact that the GFS now allocates the entries both allows
621 for new members and makes a scan handler easier to write.
623 Fix CQL lex buffer overflow.
625 SRW/SRU recordPacking. For SRW default recordPacking is string. For
626 SRU default recordPacking is string.
628 SRU protocol support for frontend server.
630 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
632 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
634 Added scan for the ZOOM shell (zoomsh).
638 * String Identifers for Schemas (Amendment 5).
639 http://lcweb.loc.gov/z3950/agency/amend/am5.html
640 Old definition for schema
641 Odr_oid *schema; /* OPT */
646 Z_InternationalString *uri;
647 #define Z_Schema_oid 1
648 #define Z_Schema_uri 2
651 * resultCount parameter to Sort Response (Amendment 1).
652 http://lcweb.loc.gov/z3950/agency/amend/am1.html
654 Support for SRW 1.0 over HTTP. This is an optional feature and
655 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
658 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
659 on the same port. SRW SearchRetrieveRequests are mapped
660 to bend_init,bend_search,bend_fetch,bend_close.
662 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
664 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
665 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
667 ZOOM connections are SRW based if schem http is used for hostname
668 in connect, e.g. z = ZOOM_connection_new("http://myserver");
669 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
671 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
672 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
673 distance=n, order=true/false, relation=le, prox unit=word. If
674 n is omitted, distance 1 is used.
676 Fixed problem with C compiler include path in wrong order.
678 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
679 on Solaris. Patch from Ko van der Sloot.
681 New MARC decode API. All new functions operate on a yaz_marc_t
682 handle. The most important new functions are: yaz_marc_create,
683 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
684 decode and destroy respectively. Decoder can produce formats
685 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
686 include/yaz/marcdisp.h.
688 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
689 to UTF-8, UCS-32, wchar_t or Latin-1.
691 * Prototypes for yaz_iconv_-functions moved to separate header
692 include/yaz/yaz-iconv.h.
694 Make a few private functions 'static' in unix.c. This prevents
695 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
697 For ZOOM connection, the options targetImplementation{Id,Name,Version}
698 are set when Init Response is received.
700 New function ZOOM_connection_error_x similar to ZOOM_connection_error
701 but returns diagnostic set as well.
703 New function yaz_strerror which is a portable wrapper for
704 strerror/strerror_r/GetLastMessage.
706 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
707 is returned for MARC. If type is "oai", then OAI MARC is returned.
709 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
714 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
716 Fix bad race conditions on SIGTERM and terminate gracefully in
719 Move retrieval (data1) module to Zebra since nobody seems to be
722 Add GRS-1 render for ZOOM using same format as yaz-client.
726 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
728 Fix broken ESpec handling in data1 module.
730 SGML reader parses comments and makes them part of the data1 tree.
732 Added several type casts so that YAZ compiles as C++ code.
734 ZOOM didn't handle PDU encoding failures properly.
736 Added more Bib-1 diagnostics (approved extensions).
738 GNU configure: better check for iconv.
740 More portable use of accept, getpeername. Check for socklen_t. Use
741 int/size_t if socklen_t is not defined.
745 PQF parser rejects bad queries - including those with extra
746 characters in them. PQF parser used to silently ignore that.
747 Cleaner API for PQF added, which allows you to get detailed
748 error information for bad queries (see yaz/pquery.h).
750 Fixed bug in ZOOM_record_get for type "database".
752 Implemented mini iconv library supporting conversions between
753 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
755 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
759 Fixed ZOOM C record cache so that preferredRecordSyntax and
760 elementSetName is used to check for already fetched records.
764 Added three members in bend_initrequest structure to facilitate
765 character set negotiation.
767 Fixed a bug in frontend server that could cause indefinite
768 loops under rare conditions.
770 Revised character set utilities (charneg.h) so that encoding
771 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
773 For PQF, directive @term <type> sets term type for Scan/Search.
774 Here <type> is general, string, numeric, null. The term type
775 is inherited - just like @attr.
777 New call odr_set_charset that sets character set conversion for
778 international-strings on a ODR stream. Prototype is:
779 int odr_set_charset(ODR o, const char *to, const char *from);
780 The InternationalString is still represented as C string in YAZ
781 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
782 won't). On the protocol level, you can use any encoding.
784 Support for UNIX sockets in ZOOM.
786 Solaris recv sometimes returns errno == ENOENT. It is treated as
787 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
789 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
790 both client and server. Code by Morten Bøgeskov.
794 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
795 that they can be used directly from Visual Basic. You must recompile
796 your windows APP if you're using ZOOM.
798 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
799 Commands "lang" and "charset" sets language and character set respectively.
800 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
801 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
803 Attributes from multiple CCL fields may be OR'ed rather than merged
804 using directive "@field or". Fields are still merged by default -
805 equivalent to "@field merge".
807 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
810 Fixed bug in zget for parameter ExtendedServicesResponse.
816 Added PQF feature: '@attr type=value' may be written as '@type=value'.
818 Client displays USR.1:SearchResult-1 (hits per term).
820 Additional Search Info for search in Generic Frontend Server.
822 Fixed CCL parsing of "field=s".
824 WIN32 installer - using the excellent NSIS software from nullsoft.
826 Fixed CCL parsing of "field = - <number>".
828 Added function yaz_marc_decode that decodes MARC for line mode
829 display or XML (similar to that used by JZKit).
831 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
832 Z39.50. But ISO/ILL was, however.
834 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
835 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
837 http://lcweb.loc.gov/z3950/agency/amend/am2.html
838 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
842 New YAZ client features: Command completion and new commands:
843 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
844 Code provided by Jacob Poulsen.
846 New call oid_trav, that visits all registered OIDs via callback.
848 Function ZOOM_record_get now returns const char pointer rather than
849 void pointer. It saves a lot of type casts.
851 For YAZ client, command "auth" now allows you to set authentication
852 in IdPass style. It is enabled when three tokens are given - order
853 is user, group and password.
855 Fix memory leaks in MARC record handling for ZOOM.
857 New option for YAZ client, -k <kilobytes> that sets
858 maximum record size. Similar to -k option for generic frontend
859 server and yaz-ztest.
861 More fixes for scan. Non-zero stepSize handled. OID's fixes.
863 Prefix query parser reports "fail" when bad attribute set is given.
865 Fix in MARC decoder. Proximity logging. Fix for attribute set
866 in scan handler for server. Patches by Shigeru Ishida.
868 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
871 Configure option --with-openssl=<dir> now works when a directory is
872 specified. Patch provided by Morten Bøgeskov.
874 New option for YAZ client, -u <auth>, that sets authentication.
876 ZOOM fix: error information was sometimes "missing", since error
877 was cleared/reset too when it shouldn't.
879 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
883 Scan for ZOOM API. New object ZOOM_scanset. New functions
884 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
885 ZOOM_scanset_destroy.
887 New ZOOM function, ZOOM_connection_last_event, that returns type
888 of last event (such as "receive data", "send data", "apdu received",
891 New ZOOM option, schema, that specifies schema for retrieval.
893 New CCL feature. Qualifiers can be aliases for one or more
894 other qualifiers (if more than one is given, OR is used).
896 ZOOM uses named result sets if target supports it.
898 Two new YAZ client commands: . (dot, which sources a script of YAZ
899 client commands), and ! (to execute shell command.). Implemented
902 Working on Debian packages.
906 YAZ client enables named result sets only if target supports it.
908 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
910 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
911 with key="host" to get same result.
913 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
914 Function Z3950_resultset_record(s) returns references to records
915 "owned" by resultset. To become owner use Z3950_record_clone.
917 Function z_ext_record handles Extended Services. Thanks to
922 CCL Parser fix: ignore token comma when dealing with and-lists.
924 Documentation updates for COMSTACK.
926 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
927 Changed prototype Z3950_records. For some functions, int parameters
928 were changed to size_t.
930 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
933 New MARC decode/display function, marc_display_exl, which properly rejects
934 non-ISO2709 records. YAZ client uses it.
938 Fix bug: local attribute set wasn't set correctly in PQF strings.
942 * Old Z39.50 codecs no longer supported.
944 Added ZOOM C binding. See http://zoom.z3950.org/
946 Renamed states for COMSTACKs to avoid confusion with events.
948 Implemented cs_look and proper cs_rcvconnect.
950 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
952 Configure detects POSIX threads on OpenBSD.
954 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
955 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
957 When error is returned from present handler, non-surrogate diagnostic
958 is returned in present response (and fetch handler is no longer called).
960 * Minor adjustments to pquery parser (PQF). Token characters may be
961 escaped by using backslash (C-style).
963 PQF parser allows string attribute values to be specified. For @attr,
964 non-numeric characters after the equal-sign are treated as strings
965 (e.g. @attr 9=title).
967 CCL trunction character may be defined (@truncation in file)
969 * function zget_ExtendedServicesRequest sets waitAction to
970 waitIfPossible (was wait).
972 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
975 CCL operator names may be set in field definition files (CCL_bibset).
976 See ccl/bib1 for an example.
978 Fixes in ASN.1 compiler for C++ compatibility.
980 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
981 and "op_or" to avoid conflict with C++.
983 Fixed problem with GNU readline detection on Redhat 7.0.
985 Added step-size for Scan backend handler.
987 Fixed bug that made the frontend server crash when no attribute
988 set was specified for scan.
990 Front-end server automatically switches to original working directory
991 when installed as an NT service. Previously -w had to be specified to
994 Added extended attributes for retrieval module (data1), so that data1
995 records carry d1_readXML/SGML attributes. d1_read also supports
996 null-data rules ( <tag/>)
998 On UNIX when POSIX threads are available, a separate library libyazthread
999 is created. Programmers should link with that library and the yaz library
1000 when using threads. The reason for the split was that some applications
1001 on Linux, such as Apache, doesn't work well when using shared objects that
1004 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1005 (or any frontend server) in SSL mode by specifying ssl: followed by
1006 address. Only tested on UNIX.
1008 Added feature for CCL module. Virtual structure s=al or s=ol generates
1009 and-list and or-list respectively instead of phrase search.
1013 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1014 log_mask_str. This was done to avoid name conflicts with other libraries
1015 (such as other PHP extensions).
1017 Added raw OID member for preferred record syntax (request_format_raw)
1018 and returned record syntax (output_format_raw) for backend fetch method.
1020 Config file yaz-config now accepts options so that it returns specific
1021 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1023 Shared library support for UNIX using GNU libtool.
1025 * Modified backend interface. Request/Response struct's replaced by
1026 one read/write C struct. For example bend_fetchrequest and
1027 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1028 Every handler - even search has to be registered in bend_init
1029 handler. This means that the YAZ library no longer refers to
1030 external functions and it makes it possible to make the whole
1031 thing a single DLL/SO.
1033 Added Segment handler for backend server.
1035 Added Zmbol/Zebra administrative functions to YAZ client.
1037 Threaded frontend server on UNIX (when POSIX Threads are available).
1038 Starting the server with option -T enables multi-threading.
1042 Added configure option --enable-comp/disable-comp to control use
1043 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1044 located in sub directory asn.
1046 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1047 in ${exec_prefix}/bin along with the other programs yaz-client and
1050 GNU automake used to maintain makefiles.
1052 Added several OID's.
1054 Changed retrieval module so that we can load records with no abstract
1055 syntax defined. Tagpaths in these records are fully composed of string
1058 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1062 On UNIX, the generated makefile now supports a proper 'make install'.
1063 The prefix can be set via GNU configure to set the install location
1064 (default is /usr/local).
1066 * YAZ programs client and ztest were renamed to yaz-client and
1067 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1068 locations, such as /usr/bin,/usr/local/bin,etc.
1070 * YAZ Header files were moved from include to include/yaz. YAZ Header
1071 files are referred to as include <yaz/log.h> rather than <log.h>.
1072 The YAZ include path (-I ..) is therefore the same as before. Programmers
1073 should update their #include statements or use -Ipath/include/yaz
1074 instead. The main motivation for doing this change is that YAZ header files
1075 can be installed in "standard" locations /usr/include,/usr/local/include
1076 without introducing conflicts, since ALL YAZ header files are stored
1077 in subdirectory yaz (under /usr/include for example).
1079 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1080 rather than project/workspace files. We switched because project files
1081 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1084 Changed name of logging function, logf, to yaz_log, to prevent name
1085 clash with some math-log functions. The YAZ header log.h defines logf
1086 to yaz_log (#define) so there should be no incompatibilities by this
1089 Added bend_start/bend_stop handlers for server. These handler are
1090 called on start/stop of server. For windows they are called whenever
1091 a service is started/stopped.
1093 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1094 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1095 in util/yc.tcl. The auto-generated C code structures are, in a few
1096 cases, incompatible with the old decoders. There are differences in the
1097 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1098 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1099 The preprocessor variable ASN_COMPILED is defined when the compiled
1100 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1101 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1102 wish to use the old encoders/decoders you can specify --disable-yc
1105 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1106 version so that it supports both new - and old version of DB Update
1108 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1109 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1110 change. The name parameter can be set to 0 in which no name is specified
1111 for the construction. The macros odr_implicit and odr_explicit sets name
1112 parameter to zero for the construction involved. New macros
1113 odr_implicit_tag and odr_explicit_tag are similar to the others,
1114 except that a name parameter is added. For programmers' that don't use
1115 ODR they probably only need to change the call to z_APDU and z_External.
1117 Added access control facility by interfacing the TCP wrapper library.
1118 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1119 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1120 name of the daemon and enables the access control as specified in
1121 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1123 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1124 den Dool <H.M.vdnDool@kub.nl>.
1126 Added reference ID parameter to most functions in server API - refer
1127 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1129 Changed name of ccl library to libccl.a (was ccl.a).
1131 Fixed bug in decoder for Explain (Category TargetInfo).
1133 Added support for GNU readline in client. Thanks to Jacob Poulsen
1134 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1136 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1137 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1138 IMPLEMENTATION! This change was made to the development version before
1139 the ZIG decided to retract the amendment. If any users MUST be
1140 compatible with the original Update definition, PLEASE CONTACT US, and
1141 we will include a separate definition corresponding to the old Update
1142 ES. Note that because of the change to the ASN.1 of the
1143 TaskPackageRecordStructure we cannot define a single structure that
1144 will support both versions.
1146 * Added const modifier to buffer parameter for some ODR/BER encoding
1147 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1148 completeWAIS, odr_dumpBER.
1150 Fixed bug in client.c which caused a crash when a scanResponse didn't
1151 contain positionOfTerm.
1153 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1154 * will cause an error in a client if a non-YAZ target sends both a
1155 * list of Scan entries and non-surrogate diagnostics.
1157 Retrieval module enhancements. Tag sets may be typed in the reference
1158 to it. From the .abs-file the "tagset" directive takes a third optional
1159 integer type for the tag set referenced. From a .tag-file the "include"
1160 directive takes a third optional type as well. The old "type" directive
1161 in the tag set itself is still recognized but acts as the default type
1164 Backend interface change. Individual Scan terms returned from bend_scan
1165 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1166 in include/backend.h.
1168 Retrieval module enhancements. Multiple tag sets and attribute sets may
1169 be specified in abstract syntax specs. Revised the error/warning for
1170 logging messages reported by the retrieval module when reading the
1173 Object Identifier system (oid_..) changed. The API is backwards
1174 compatible but the oid-routines now allocates new OID's when needed.
1175 Raw OID's may be specified in oid_getvalbyname.
1177 YAZ now uses GNU configure to generate Makefile(s).
1179 * Minor changes in some of the member names of DeleteResultSetRequest and
1180 DeleteResultSetResponse. See include/proto.h.
1182 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1183 and added member 'languages' in TargetInfo (which was missing).
1185 Changed the way attribute sets are handled in the retrieval
1186 module. These are now cached, just like the abstract syntaxes
1189 Changed YAZ so that it links with compiled ASN.1.
1191 Added Explain-schema definitions and mapping routines. The following
1192 Explain categories have been implemented: AttributeDetails,
1193 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1195 Fixed minor bug in Windows version of Server Library.
1197 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1199 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1201 Added EXTERNAL: UNIverse Resource Report (non-standard).
1203 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1204 ENUMERATED and SET OF.
1206 * Added 'const' to some of the char pointer arguments for the
1207 functions, data1_read_node, data1_getelementbytagname,
1208 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1211 Fixed bug in data1_insert_taggeddata - the last_child member of
1212 parent wasn't initialised.
1214 * Changed data1_read_record and data1_read_node so that the supplied
1215 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1216 doesn't refer to any parts of the "SGML"-buffer.
1218 Fixed bug in server library (Windows version of statserv_remove).
1220 * Changed code so that it compiles as C++. The type definition
1221 of Odr_fun which is a member of Odr_arm was changed. The result is,
1222 that an explicit typecast is needed for the fun pointer when
1223 using Odr_arm - as in:
1224 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1226 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1228 Implemented the new structured date and time definition as approved
1229 by the ZIG. Added schemaId element to the specificTag in Espec-1
1230 (also approved at the last ZIG). Thanks to RVDM.
1232 Added some Object identifiers (RVDM).
1234 Changed the Update Extended Service (RVDM).
1236 Added command "refid" to client which specifies referenceId for
1237 the following requests.
1239 Implemented extended service handling for server. See ztest.c
1240 for an example as well as backend.h. New handlers are registerd
1241 in the Init handler.
1243 * Changed interface for sort in server.
1245 Added new members to statserv_options_block. It allows a server
1246 to read options from another source than just the command line. Thanks
1247 to Charles Woodfield.
1249 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1250 renamed to zboolean. Some C++ compilers complained about the name.
1252 Minor changes to gils.abs. Added index 's' (sort) on title
1253 and date/time-last-modified.
1255 --- 1.4pl2 1998/1/30
1257 Fixed bug in server library regarding inetd mode (-i). This bug
1258 was introduced by release 1.4.
1260 --- 1.4pl1 1998/1/29
1262 Added sort facility in client and backend server interface.
1264 Fixed problem with dependencies in Makefile(s).
1266 Fixed bugs for encoders/decoders of extended services and
1269 Implemented sub-tree feature for schemas. Sub-trees are
1270 referenced in *.abs-files. See explain.abs for an example
1271 of the use of this feature.
1273 Modified bib1.att; local attributes for ANY didn't include
1274 ANY itself (only affects use of the retrieval module).
1276 Fixed bug in plain SGML reader in function data1_read_node:
1277 tags with prefix "var" was incorrectly interpreted as variants.
1279 Added feature "sub-schemas" to enable references to - and definitions
1280 of - group of elements.
1282 * Removed member parent from type data1_element (in data1.h).
1284 Implemented function odr_nullval() that returns the value of
1287 * Removed member num_children from data1_node (in data1.h).
1289 Made NT service interface part of the server library. The
1290 function statserv_main uses the NT service when required and
1291 calls the statserv_start / statserv_close routines.
1293 Routine zget_SearchRequest and zget_PresentRequest fills
1294 resultSetName/Id member with "default" instead of "Default".
1296 Fixed memory leak in server. Request queue member wasn't freed.
1298 Fixed nmem_exit so that memory is freed.
1302 Revised the CCL parser utility to be thread safe.
1304 Added function, oid_ent_to_oid, to replace the function
1305 oid_getoidbyent, which is not thread safe.
1307 * Added nmem_init and nmem_exit to initialize and release
1308 NMEM resources. Function nmem_init should be called once in the
1309 initial thread before NMEM/ODR is used. statserv.c and client.c
1310 have been changed accordingly. The change was necessary to make
1311 NMEM thread safe. The NMEM memory pool is shared amongst threads
1312 in a process. Unix-based applications will still work fine without
1315 Added NT Services interface for the the Z39.50 (statserv) Server.
1316 Refer to the ztest.c source on the usage.
1318 Windows 95/NT port using MSVC5.0. Project files are included in the
1321 * Defined new 'global' handle for the retrieval (data1) system. The
1322 new handled, data1_handle, describes the state of the data1 system.
1323 This handle is passed as first argument to virtually all
1324 data1 related routines. The functions data1_create and data1_destroy
1325 creates and destroys a data1 handle respectively.
1327 Added ODR encode stream member to all backend request structures
1328 init, search, scan etc. This stream should be used to allocate all
1329 memory used for the response when thread safe operation is needed.
1331 Changed the comstack utility, cs_addstr, to be thread safe. The
1332 returned hostname string returned by the function is now part the
1335 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1336 function. The cs_straddr takes a COMSTACK handle as argument, so this
1337 function must be used after cs_create and before bind/connect.
1338 This function is thread safe.
1340 Moved test server to 'ztest' directory - generic server code still
1341 in 'server' directory.
1343 Made prefix query (pquery.c) utility thread safe.
1345 Added new function modifier YAZ_EXPORT to 'export' public DLL
1346 functions when using windows (see include/yconfig.h).
1348 Added definitions to the OID database (util/oid.c) (RVDM).
1350 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1352 Added call to ccl_rpn_delete in client program.
1354 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1355 release of RPN structure.
1357 Added support for C++, headers uses extern "C" for public definitions.
1358 With input from RVDM.
1360 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1361 Thanks to Ronald van der Meer (RVDM).
1363 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1365 Added support for private extensions to the OID database
1366 (oid_setprivateoids()). Thanks to RVDM.
1368 Added optional, physical ANY (key replication)
1370 Fixed null-reference problem in GRS-1 output filter.
1372 Proximity operator added to Prefix Query Format (PQF).
1374 In test client command "base" accepts multiple databases.
1376 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1380 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1382 Smallish bug-fixes in the new encoders/decoders (explain).
1384 Bug fixed in DeleteRequest.
1386 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1388 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1390 Added SOIF syntax (using private OID for now) to retrieval module and client.
1392 Added Update extended service.
1394 Added SearchResult-1 additional info structure.
1396 Added optional CCL (ISO8777) interpreter as separate module. Available
1399 --- 1.2 1996/6/10 (1st anniversary release)
1401 Added Summary record syntax. Lightly tested.
1403 Added OPAC record syntax. Untested.
1405 Added ResourceReport service encoders/decoders. Untested.
1407 Fixed bug in z_Unit - wrong tagging on unitSystem.
1409 Fixed bug in the DiagRecs decoder.
1411 Added options for max PDU size and session timeout to frontend-server.
1413 Added documentation of query-language parsers and other supporting utilities.
1415 [frontend-server] Added Attribute set to the bend_scanrequest API.
1417 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1418 surrogate diagnostics were generated.
1420 [retrieval] Allow multiple local values for attribute.
1422 [retrieval] Allow multiple attributes per element in .abs files. index type.
1424 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1426 --- 1.1pl2 1996/4/10
1428 Minor changes, mostly specific to Zebra's requirements (retrieval)
1432 Repaired bug in frontend server when running multiple listening
1433 endpoints in dynamic mode.
1435 z_External() now won't break if a known, ASN.1 value comes encapsulated
1436 in an octet-string. The value will pass through unmodified in an Odr_oct.
1438 Added a bit of code to the demo client to decode & display
1439 ASN.1-structured records represented in the octet-aligned branch of
1440 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1442 Added z_ext_getentbyref() to the ASN module. Doc updated.
1444 * Completed the SCAN definition in the ASN module. This may break SCAN
1445 code based on older YAZ-versions at compile-time. The fix is easy -
1448 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1449 under the SCAN definition. Remember to initialize this, server-people.
1451 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1452 that this does not extend to ODR and ASN.
1454 Comstack allows insertion of established socket (primarily for
1455 inetd-operation of servers). Doc updated.
1457 Front-end server can now start from the inetd in TCP mode. Doc
1460 --- 1.0pl4 1996/1/24
1464 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1465 the rank and record number.
1467 Adjustments to the frontend server.
1469 Fixed diagnostic BER dumper. It ignored the file argument.
1473 Various changes to retrieval module.
1475 Changed the union discriminators of the protocol files from enums to
1476 ints paired with #defines.
1478 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1481 *Changed operator in the RPN structure to 'roperator', again to avoid a
1484 Fixed problems in Explain decoders/encoders.
1486 --- 1.0pl2 1995/12/6
1488 Memory bug in log module fixed.
1490 --- 1.0pl1 1995/12/5
1492 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1494 Bug in Explain DatabaseInfo module fixed.
1496 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1500 The shift to v1.0 signals that we now consider the *core* functionality
1501 of YAZ reasonably stable (the core being more or less equivalent to
1502 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1503 tested (Explain not at all - though that will happen soonish).
1505 Minor changes to code to support Windows port.
1507 Various minor changes after we're getting to use GRS-1 & co. more.
1509 Added Espec-1 format.
1511 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1512 of the protocol and it cannot be selected when encoding (maps into 'string'
1513 when decoding). Needed to talk to some servers.
1515 Demo client can request simple element set names.
1517 Added Diagnostic Format encoders/decoders.
1519 Added simple Close handling to frontend server (no hooks for resource
1520 reporting yet), and demonstration client.
1522 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1524 --- 1.0b3 1995/08/24
1526 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1527 handled incorrectly when records were requested in the searchResponse. This
1528 will only affect you if you use the frontend-server.
1530 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1531 Test-client will ask for and print GRS1. Ztest will return dummy records
1534 Added Explain encoders/decoders to the service-level API. Untested.
1536 Added Extended Services: Item Order encoders and decoders to the Service-
1537 level API. Untested. We could use a recent copy of the pertinent bits
1538 of the ILL protocol to add those bits.
1540 Added diagnostic format 1 encoders/decoders to the service-level API.
1543 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1544 odr_cons.c, which causes a more correct output.
1546 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1547 was always set to 0 when no records were requested in the searchRequest.
1549 * Added better external-handling. This shouldn't harm old code that
1550 *encodes* externals. It can break code that looks for a
1551 'single-ASN1-type' representation, since those types that are known
1552 are now decoded immediately. Look at the SUTRS sample code in
1553 seshigh.c and client.c. Documentation updated.
1555 Handling of structured records in bend_fetchresponse. Length -1 marks
1556 structured record, type is deduced from format field.
1558 --- 1.0b2 1995/06/27
1559 Fairly quick maintenance release to add SUTRS support.
1561 Fixed handling of SUTRS records in the demonstration client.
1563 * Added format field to the bend_fetchrequest and bend_fetchresponce
1564 structures of the backend API (frontend server). When the record is
1565 returned, the value of the format field is mapped to an OID. The
1566 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1567 of the record. The special value VAL_NONE in the bend_request means
1568 that no specific format was requested by the client. Documentation
1569 updated accordingly. Test server (ztest) will return a fixed dummy
1570 SUTRS record if your client requests SUTRS.
1572 Documentation updated accordingly.
1574 You can now set external libraries and RANLIB support in the top-level
1578 First public release.
