1 Possible compatibility problems with earlier versions marked with '*'.
3 Added new yaz-client, xmles, which takes a (private) OID and
4 a document to be sent as an extended service request.
6 Describe new yaz-client commands wait_response and set_auto_wait.
10 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
11 MARC output rather than returning "new" buffer.
13 yaz-client warns about unknown init options.
15 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
19 Added support for SRW sort in Generic Frontend Server. Patch
20 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
21 sortKeys - or NULL if none is provided.
23 Fixed bug #307: It was impossible to specify indefinite/no timeout
24 for ZOOM_event. Special timeout value -1 now means indefinite timeout
27 Added support for multiple languages and charsets to be specified in
28 ZOOM. Each charset/language is separated by a blank. If negotiation is
29 in effect in init-response, Option
30 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
31 Code based on patch by Vasiliy Osadchuk.
33 Fixed bug #306: infinite recursion that occurred when calling
34 yaz_log_level_init as the first call (before other log level or
37 Fixed bug in scan handling in front end server: if preferred-Position-In-
38 Response was non-present, a NULL pointer referece was performed.
42 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
43 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
44 now defined for all those error codes. So instead of putting 109 in
45 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
46 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
48 Modified the yaz-marcdump utility to skip garbage bytes between MARC
51 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
53 Program yaz-client now exits and produces an error message if multiple
54 Z39.50 servers are specified on the command line (none or one allowed
57 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
62 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
64 Fixed bug #272: Preserve spacing for CCL terms.
68 Added support for virtual hosts and multiple backend servers for
69 the YAZ frontend server. The configution is XML based and
70 support specificition of CQL to RPN mappings and explain information.
71 See section "Virtual Hosts" in the YAZ manual.
73 Extended OPAC display utility. OPAC display utility renders
74 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
75 to supplement yaz_marc_decode_wrbuf.
77 Fixed a bug in MARC decoder that could caused it to crash for some
78 invalid MARC records. More diagnostics and warnings where added in
79 XML output (warnings, etc are stored in comments).
83 Fixes for UNIX domain sockets. Bug #261.
85 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
87 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
88 Added yaz_marc_subfield_str which defines subfield lead string which is
89 used in YAZ_MARC_LINE format. Default string is blank+$. Added
90 yaz_marc_endline_str which defines end of fields string used in
91 YAZ_MARC_LINE format. Default string is newline.
93 Experimental support for MarcXChange. This format can be produced
94 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
95 http://www.bs.dk/standards/MarcXchange.xsd
97 Added yaz-client commands scansize that sets maximum number of
98 entries to be returned by scan.
100 --- 2.0.32 2005/01/11
102 Added support for SRW scan in yaz-client and Generic Frontend Server.
104 * Added whereInList member to SRW Scan Term.
106 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
108 Fixed NMEM system to return aligned blocks on the smallest boundaries
109 that are suitably aligned for all possible types on the particular
110 architecture YAZ is being built for.
112 --- 2.0.30 2005/01/04
114 Fixed numerious warnings that was issued with newer versions of GCC.
116 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
117 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
120 Make YAZ Generic Frontend Server slightly faster.
122 Enhance (and reduce) logging for Generic Frontend Server.
124 Revert YAZ log system so that it flushes every write operation
125 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
127 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
128 instead of LOG_, due to name clash with syslog(3). LOG_ are still
129 present. New applications should define YAZ_USE_NEW_LOG=1 - this
130 will effectively disable old definitions.
132 --- 2.0.28 2004/11/09
134 Added yaz_log_time_format which specifies log format using
137 Added yaz_log_module_level which returns mask for a module. Value
138 is non-zero mask a if module is enabled; zero if disabled.
140 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
141 in include/yaz/cql.h.
143 Fixed bug #176: Dont throw diagnostics on empty SRU args.
145 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
147 Fixed bug #172: RPM builds does not enable SSL.
149 Doxyfile.in part of dist. Doxyfile generated by configure.
151 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
152 are given and the corresponding component does not exist.
154 Extend CCL documentation in YAZ reference. Describe r=r.
156 --- 2.0.26 2004/10/01
158 Fixed MARC->MARCXML conversion to properly deal with
159 fields, subfields, indicators having non-ASCII characters.
161 Fixed MARC->MARCXML conversion so that ASCII control characters
162 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
165 Added YAZ GFS support for conversion from Z39.50 surrogate
166 diagnostics to SRW surrogate diagnostics.
168 Bug fix: YAZ GFS did not return schema in explainResponse.
170 --- 2.0.25 2004/09/30
172 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
173 now converts recordSchema to elementSetName as well as schema URI.
175 Fixed bug in COMSTACK that prevented HTTP request packages from being
178 --- 2.0.24 2004/09/29
180 Added CCL facility r=r "range" which is similar to r=o "ordered" but
181 does not require white-space before and after the dash in a range, e.g.
182 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
185 Fixed a few AC_TRY_LINK configure tests that did not operate properly
186 due to new GCC removing "redundant" code.
188 Added yaz-client commands scanpos and scanstep that sets preferred
189 position and step-size for scan.
191 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
193 Added CCL utility ccl_qual_buf which parses one or more CCL
194 spec lines in a buffer.
196 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
197 of name and value - ignoring empty lines and comments.
199 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
201 Added odr_get_element_path which returns current element path for an
202 ODR handle. This utility is useful in error handling or user-defined
205 Added ODR_PRINT utility odr_set_stream which is is a more generic
206 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
207 to a write function and pointer to close function. The close function - if
208 non-NULL - will be called during odr_destroy.
210 Fixed bug in CCL parser where truncation char was not removed from
211 right side when truncation=both was in effect.
213 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
216 --- 2.0.23 2004/08/11
218 Fix buffer overrun in CQL parser when dealing with proximity (%).
220 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
221 to UTF-8/UCS conversion is now only based on codetables.xml.
223 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
225 --- 2.0.22 2004/08/06
227 Add support for more "commit changes" in ZOOM (uses Extended Services).
229 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
232 Yet another small fix for configure of SSL.
234 --- 2.0.21 2004/05/14
236 Fix SSL libs for configure when --with-openssl=DIR is given.
238 --- 2.0.20 2004/05/10
240 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
242 SSL comstack now uses yaz.pem certificate file on server side
243 by default. Certificate filename can be configured by calling
244 comstack function cs_set_ssl_certificate_file before cs_bind is used.
246 Fix bug regarding multiple calls to ZOOM_connection_connect.
248 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
250 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
251 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
253 ZOOM now allows inspection of X509 peer certificate for verification.
254 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
256 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
257 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
258 as "modular" but it simplifies things.
260 Added cs_get_peer_certificate to that returns peer X509 PEM.
262 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
263 NULL if SSL is unavailable.
265 Documentation about MARC decoding tools.
267 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
269 --- 2.0.19 2004/03/30
271 Rename CHANGELOG to NEWS to follow GNU style packing.
273 Fix bug with missing initialization of member in init_diagnostics.
274 This bug affects threaded version of GFS server.
276 --- 2.0.18 2004/03/20
278 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
281 Ensure zlib.dll is packed with Windows install.
283 --- 2.0.17 2004/03/17
285 Fix encoding of xsd:string to use text instead of CDATA.
287 Fix endless loop in CQL parser with unbalanced ".
289 Use a more compact way to store MARC-8 conversion tables.
291 --- 2.0.16 2004/03/16 Debian only
293 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
296 Update CQL parser to use new CQL 1.1 modifiers for booleans and
301 --- 2.0.15 2004/03/01
303 Another fix for decoding of XML packed records.
305 --- 2.0.14 2004/02/25
307 Fixes for Chunked encoding. White space not ignored after length spec.
309 Update NS and use default NS for SRW diagnostic elements.
311 --- 2.0.13 2004/02/23
313 Implement ZOOM_resultset_cache_reset which resets record cache.
315 Implement ZOOM_resultset_sort which sorts a result set.
317 Implement chunked HTTP transfer.
319 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
321 --- 2.0.12 2004/02/16
323 Added member 'schema' to bend_explain_rr structure so that backend
324 can specify explain record identifier. Defaults to Zeerex 2.0.
326 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
328 --- 2.0.11 2004/02/16
330 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
333 Added init command for yaz-client which sends "extra" init request.
335 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
336 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
338 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
340 Make ZOOM error code for "invalid query".
342 Fixed compilation for SSL which wasn't properly enabled for all platforms.
344 --- 2.0.10 2004/02/05
346 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
349 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
351 Added option -p <file> to make Generic Frontend Server to write PID file.
353 Added option -D to put Generic Frontend Server in background on its own.
355 Make ZOOM C recognize option "password". If unset, "pass" is used
356 (for backwards compatibility).
358 Fixed a bug in Generic Frontend Server that could make it crash if a
359 client sets characterSetNegotation bit, but didn't pass negotiation stuff
362 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
363 Must be issued before open, in order to be in effect.
365 --- 2.0.9-6 2004/01/12 Debian/Windows
367 Make the SRU server more picky WRT unknown params, etc.
369 Bug fix: ZOOM scan response didn't return displayTerm - when present.
371 New YAZ client command, options, that sets Z39.50 options.
373 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
374 options from a string of tokens (one token for each option bit).
376 Update SRW diagnostic code messages.
378 --- 2.0.9-5 2004/01/07 Debian/Windows
380 Handle user defined stylesheet for SRW/SRU.
382 --- 2.0.9-4 2004/01/06 Debian/Windows
384 Fix bug in decoding of Content-Length.
386 --- 2.0.9-3 2004/01/06 Debian/Windows
388 Fix a bug with decoding of XML packed records.
390 --- 2.0.9-2 2004/01/05 Debian only
392 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
394 Fix bug in SRW/SRU diagnostics decoding.
398 Fixed bug in Generic Frontend Server which could drop records exceeding
399 preferred message size. Reported and fixed by Irina Dijour.
401 Fixed calculation of package size for structured records in Generic
402 Frontend Server. Reported and fixed by Irina Dijour.
404 Fixed namespace for SRW/SRU diagnostics.
406 Fixed SEGV in yaz-client that occured for HTTP connection errors.
410 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
411 this version is incompatible with version 1.0 and older YAZ SRW/SRU
414 CQL changes to reflect recent changes to the specification:
415 * Documentation talks about context sets instead of index sets.
416 * Documentation talks about indexes instead of qualifiers.
417 * The CQL-to-PQF transformer's configuration file now uses
418 "index.set.name = <attributes>" instead of the old form
419 "qualifier.set.name = <attributes>". (Both forms are still
420 understood but the latter is deprecated.)
421 * CQL terms with no explicit index specified are now interpreted as
422 cql.serverChoice instead of srw.serverChoice (which of course
423 behaves exactly the same.)
427 MARC conversion can now generate ISO2709 output in another
428 character set. yaz-marcdump uses this facility if you invoke it
431 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
432 functions from there can be used from C++.
436 Frontend server now transfers memory from decoded packages to stream
439 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
440 references to show up.
442 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
443 the ZOOM Abstract API. The older names for the same options are still
444 also supported for the benefit of old applications.
446 ZOOM-C supports "implementationId" and "implementationVersion" options
447 to go along with "implementationName". These allow the user code to
448 specify identification strings to be sent to servers.
449 Add OID for the new ExtLite attribute set.
451 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
452 as requested/supplid by Ere Maijala <ere@atp.fi>
454 For generic frontend server, reverse the order of
455 "toolkit-supplied / application-supplied" strings sent as implementationId,
456 Name and Version. Also, remove the spaces around the slash. This brings
457 the GFS in line with the behaviour of ZOOM-C on the client side.
459 Add function ZOOM_scanset_display_term.
461 yaz-client shows scan displayTerm if present.
463 Utility yaz-iconv is now installed by default along with the man page
466 Extend configure check for OpenSSL to use pkg-config where available (such
469 Incorporate patch by Morten Bogeskov which allows a Unix file socket
470 server to specify uid/gid/mask for socket using the format
471 unix:[user=uid,][group=gid,][umask=mask,]file=path
472 If file= is omitted the existing format is assumed, e.g.
474 in which case the mask is 0666 (rw for everybody).
476 Major restructure of YAZ source. All source in libyaz is in src directory.
477 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
478 util (utility programs such as ASN.1 compiler, yaz-marcdump).
480 Added man page for utility yaz-marcdump (used to be called marcdump).
481 yaz-marcdump is installed by 'make install'.
483 Fixed a memory leak in Generic Frontend Server that occurred when decoding
484 of incoming package failed.
486 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
488 Change prototype of odr_perror: add const to message string.
490 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
492 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
493 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
494 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
495 DNS lookup. There should not be any compatibility problems with this
496 assuming that blocking=1 or 0 is used.
498 Fix bad reference in UNIX comstack in function cs_addrstr.
500 Fix for compilation on AIX.
502 The generic front-end server (server/seshigh.c) now supports returning
503 Init diagnostics to the client in User-information-field, in
504 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
509 Allow any CQL relation (not just all,any,exact,scr).
511 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
512 that features the same UI.
514 Implemented command update0 in YAZ client which is equivalent to
515 update but uses old of Ext Update ASN.1.
517 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
518 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
519 Previously no OID was used for this info.
521 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
522 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
523 returns 'malformed search term' otherwise.
525 SortResponse member resultCount now set to NULL in sort handler of
528 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
531 Add three new utility functions for translating OIDs between various
532 formats -- symbolic name such as "Usmarc", minus-1-terminated int
533 arrays and dotted strings such as "1.2.840.10003.9.5.1":
534 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
535 char *oid_to_dotstring(const int *oid, char *oidbuf);
536 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
538 Reverted modifications for ES Update definition for z_IU0Update
539 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
540 is back to YAZ 2.0.2.
542 String value attributes for CCL parser.
544 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
545 which their FirstSearch server returns in Init responses, sometimes
546 carrying useful diagnostic information when Init fails. This has the
547 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
548 "z39.50/oclcui.asn", where its definition is somewhat different from
549 what OCLC document on their web-site, as required to interoperate with
552 Support for anonymous authentication in yaz-client. Use the command
555 * Fix the OID of the Index Data-local "admin" Extended Service from
556 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
557 the 1000, which indicates a locally-defined OID, was a mistake.
561 Fix CCL directive @case handling so that it affects string match for
562 both CCL keywords and qualifiers.
564 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
565 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
566 Decoder has been updated with ASN.1 changes as listed in
567 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
568 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
569 z_IUUpdate, remains unchanged.
571 ZOOM_record_get may now return a record in a specific character set.
572 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
573 "from" is the character set of record as returned by target. "to" is
574 the character set to be returned. If omitted, "to" is UTF-8.
576 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
578 New ODR utility, odr_getelement, which returns name of element for
579 which encoding/decoding failed.
581 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
582 in cases where a required element was omitted.
584 Bug fix: some MARC8 sequences were not converted.
586 New ZOOM option "step" which specifies number of records to be
587 retrieved in one chunk. Used in conjunction with "start" and "count".
589 SRW support for yaz-client. Use scheme http: to use it, e.g.
592 yaz-client no longer does (un)intelligent character set conversions
593 by default. Can be enabled with charset and marc_charset commands.
595 xmalloc trace fix for 64-bit systems such as DEC alpha.
597 Solaris 2.6 compile fix.
599 New function, cql_strerror() translates SRW error codes, as returned
600 by cql_transform_error(), into human-readable English strings. Used
601 in yaz-client diagnostics when appropriate.
603 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
604 converts it into a type-1 query which is sent to the server. This
605 makes CQL available for use with all Z-servers, as opposed to the tiny
606 minority that can handle CQL queries themselves.
610 New Debian package layout similar to the Redhat Package layout.
612 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
613 and search result respectively.
617 Redhat package is now several packages: libyaz (runtime libraries),
618 libyaz-devel (development and documentation, and yaz (utility programs).
619 Package spec file by Morten Bøgeskov.
621 New member 'schema' in struct bend_fetch_rr which the name of requested
622 schema (SRW/SRU) for record (or NULL if none was given). The fetch
623 handler MAY set this to reflect the schema of the returned record.
625 New member 'display_term' in struct scan_entry. GFS now sets member entries
626 and allocates scan entries to be filled by user scan handler. In previous
627 version, entries member was allocated by the scan handler. That still works,
628 but the GFS will ignore member display_term - assuming it was NOT set by
629 the handler. The fact that the GFS now allocates the entries both allows
630 for new members and makes a scan handler easier to write.
632 Fix CQL lex buffer overflow.
634 SRW/SRU recordPacking. For SRW default recordPacking is string. For
635 SRU default recordPacking is string.
637 SRU protocol support for frontend server.
639 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
641 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
643 Added scan for the ZOOM shell (zoomsh).
647 * String Identifers for Schemas (Amendment 5).
648 http://lcweb.loc.gov/z3950/agency/amend/am5.html
649 Old definition for schema
650 Odr_oid *schema; /* OPT */
655 Z_InternationalString *uri;
656 #define Z_Schema_oid 1
657 #define Z_Schema_uri 2
660 * resultCount parameter to Sort Response (Amendment 1).
661 http://lcweb.loc.gov/z3950/agency/amend/am1.html
663 Support for SRW 1.0 over HTTP. This is an optional feature and
664 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
667 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
668 on the same port. SRW SearchRetrieveRequests are mapped
669 to bend_init,bend_search,bend_fetch,bend_close.
671 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
673 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
674 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
676 ZOOM connections are SRW based if schem http is used for hostname
677 in connect, e.g. z = ZOOM_connection_new("http://myserver");
678 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
680 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
681 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
682 distance=n, order=true/false, relation=le, prox unit=word. If
683 n is omitted, distance 1 is used.
685 Fixed problem with C compiler include path in wrong order.
687 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
688 on Solaris. Patch from Ko van der Sloot.
690 New MARC decode API. All new functions operate on a yaz_marc_t
691 handle. The most important new functions are: yaz_marc_create,
692 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
693 decode and destroy respectively. Decoder can produce formats
694 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
695 include/yaz/marcdisp.h.
697 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
698 to UTF-8, UCS-32, wchar_t or Latin-1.
700 * Prototypes for yaz_iconv_-functions moved to separate header
701 include/yaz/yaz-iconv.h.
703 Make a few private functions 'static' in unix.c. This prevents
704 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
706 For ZOOM connection, the options targetImplementation{Id,Name,Version}
707 are set when Init Response is received.
709 New function ZOOM_connection_error_x similar to ZOOM_connection_error
710 but returns diagnostic set as well.
712 New function yaz_strerror which is a portable wrapper for
713 strerror/strerror_r/GetLastMessage.
715 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
716 is returned for MARC. If type is "oai", then OAI MARC is returned.
718 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
723 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
725 Fix bad race conditions on SIGTERM and terminate gracefully in
728 Move retrieval (data1) module to Zebra since nobody seems to be
731 Add GRS-1 render for ZOOM using same format as yaz-client.
735 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
737 Fix broken ESpec handling in data1 module.
739 SGML reader parses comments and makes them part of the data1 tree.
741 Added several type casts so that YAZ compiles as C++ code.
743 ZOOM didn't handle PDU encoding failures properly.
745 Added more Bib-1 diagnostics (approved extensions).
747 GNU configure: better check for iconv.
749 More portable use of accept, getpeername. Check for socklen_t. Use
750 int/size_t if socklen_t is not defined.
754 PQF parser rejects bad queries - including those with extra
755 characters in them. PQF parser used to silently ignore that.
756 Cleaner API for PQF added, which allows you to get detailed
757 error information for bad queries (see yaz/pquery.h).
759 Fixed bug in ZOOM_record_get for type "database".
761 Implemented mini iconv library supporting conversions between
762 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
764 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
768 Fixed ZOOM C record cache so that preferredRecordSyntax and
769 elementSetName is used to check for already fetched records.
773 Added three members in bend_initrequest structure to facilitate
774 character set negotiation.
776 Fixed a bug in frontend server that could cause indefinite
777 loops under rare conditions.
779 Revised character set utilities (charneg.h) so that encoding
780 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
782 For PQF, directive @term <type> sets term type for Scan/Search.
783 Here <type> is general, string, numeric, null. The term type
784 is inherited - just like @attr.
786 New call odr_set_charset that sets character set conversion for
787 international-strings on a ODR stream. Prototype is:
788 int odr_set_charset(ODR o, const char *to, const char *from);
789 The InternationalString is still represented as C string in YAZ
790 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
791 won't). On the protocol level, you can use any encoding.
793 Support for UNIX sockets in ZOOM.
795 Solaris recv sometimes returns errno == ENOENT. It is treated as
796 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
798 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
799 both client and server. Code by Morten Bøgeskov.
803 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
804 that they can be used directly from Visual Basic. You must recompile
805 your windows APP if you're using ZOOM.
807 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
808 Commands "lang" and "charset" sets language and character set respectively.
809 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
810 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
812 Attributes from multiple CCL fields may be OR'ed rather than merged
813 using directive "@field or". Fields are still merged by default -
814 equivalent to "@field merge".
816 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
819 Fixed bug in zget for parameter ExtendedServicesResponse.
825 Added PQF feature: '@attr type=value' may be written as '@type=value'.
827 Client displays USR.1:SearchResult-1 (hits per term).
829 Additional Search Info for search in Generic Frontend Server.
831 Fixed CCL parsing of "field=s".
833 WIN32 installer - using the excellent NSIS software from nullsoft.
835 Fixed CCL parsing of "field = - <number>".
837 Added function yaz_marc_decode that decodes MARC for line mode
838 display or XML (similar to that used by JZKit).
840 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
841 Z39.50. But ISO/ILL was, however.
843 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
844 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

847 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
851 New YAZ client features: Command completion and new commands:
852 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
853 Code provided by Jacob Poulsen.
855 New call oid_trav, that visits all registered OIDs via callback.
857 Function ZOOM_record_get now returns const char pointer rather than
858 void pointer. It saves a lot of type casts.
860 For YAZ client, command "auth" now allows you to set authentication
861 in IdPass style. It is enabled when three tokens are given - order
862 is user, group and password.
864 Fix memory leaks in MARC record handling for ZOOM.
866 New option for YAZ client, -k <kilobytes> that sets
867 maximum record size. Similar to -k option for generic frontend
868 server and yaz-ztest.
870 More fixes for scan. Non-zero stepSize handled. OID's fixes.
872 Prefix query parser reports "fail" when bad attribute set is given.
874 Fix in MARC decoder. Proximity logging. Fix for attribute set
875 in scan handler for server. Patches by Shigeru Ishida.
877 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
880 Configure option --with-openssl=<dir> now works when a directory is
881 specified. Patch provided by Morten Bøgeskov.
883 New option for YAZ client, -u <auth>, that sets authentication.
885 ZOOM fix: error information was sometimes "missing", since error
886 was cleared/reset too when it shouldn't.
888 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
892 Scan for ZOOM API. New object ZOOM_scanset. New functions
893 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
894 ZOOM_scanset_destroy.
896 New ZOOM function, ZOOM_connection_last_event, that returns type
897 of last event (such as "receive data", "send data", "apdu received",
900 New ZOOM option, schema, that specifies schema for retrieval.
902 New CCL feature. Qualifiers can be aliases for one or more
903 other qualifiers (if more than one is given, OR is used).
905 ZOOM uses named result sets if target supports it.
907 Two new YAZ client commands: . (dot, which sources a script of YAZ
908 client commands), and ! (to execute shell command.). Implemented
911 Working on Debian packages.
915 YAZ client enables named result sets only if target supports it.
917 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
919 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
920 with key="host" to get same result.
922 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
923 Function Z3950_resultset_record(s) returns references to records
924 "owned" by resultset. To become owner use Z3950_record_clone.
926 Function z_ext_record handles Extended Services. Thanks to
931 CCL Parser fix: ignore token comma when dealing with and-lists.
933 Documentation updates for COMSTACK.
935 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
936 Changed prototype Z3950_records. For some functions, int parameters
937 were changed to size_t.
939 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
942 New MARC decode/display function, marc_display_exl, which properly rejects
943 non-ISO2709 records. YAZ client uses it.
947 Fix bug: local attribute set wasn't set correctly in PQF strings.
951 * Old Z39.50 codecs no longer supported.
953 Added ZOOM C binding. See http://zoom.z3950.org/
955 Renamed states for COMSTACKs to avoid confusion with events.
957 Implemented cs_look and proper cs_rcvconnect.
959 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
961 Configure detects POSIX threads on OpenBSD.
963 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
964 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
966 When error is returned from present handler, non-surrogate diagnostic
967 is returned in present response (and fetch handler is no longer called).
969 * Minor adjustments to pquery parser (PQF). Token characters may be
970 escaped by using backslash (C-style).
972 PQF parser allows string attribute values to be specified. For @attr,
973 non-numeric characters after the equal-sign are treated as strings
974 (e.g. @attr 9=title).
976 CCL trunction character may be defined (@truncation in file)
978 * function zget_ExtendedServicesRequest sets waitAction to
979 waitIfPossible (was wait).
981 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
984 CCL operator names may be set in field definition files (CCL_bibset).
985 See ccl/bib1 for an example.
987 Fixes in ASN.1 compiler for C++ compatibility.
989 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
990 and "op_or" to avoid conflict with C++.
992 Fixed problem with GNU readline detection on Redhat 7.0.
994 Added step-size for Scan backend handler.
996 Fixed bug that made the frontend server crash when no attribute
997 set was specified for scan.
999 Front-end server automatically switches to original working directory
1000 when installed as an NT service. Previously -w had to be specified to
1003 Added extended attributes for retrieval module (data1), so that data1
1004 records carry d1_readXML/SGML attributes. d1_read also supports
1005 null-data rules ( <tag/>)
1007 On UNIX when POSIX threads are available, a separate library libyazthread
1008 is created. Programmers should link with that library and the yaz library
1009 when using threads. The reason for the split was that some applications
1010 on Linux, such as Apache, doesn't work well when using shared objects that
1013 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1014 (or any frontend server) in SSL mode by specifying ssl: followed by
1015 address. Only tested on UNIX.
1017 Added feature for CCL module. Virtual structure s=al or s=ol generates
1018 and-list and or-list respectively instead of phrase search.
1022 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1023 log_mask_str. This was done to avoid name conflicts with other libraries
1024 (such as other PHP extensions).
1026 Added raw OID member for preferred record syntax (request_format_raw)
1027 and returned record syntax (output_format_raw) for backend fetch method.
1029 Config file yaz-config now accepts options so that it returns specific
1030 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1032 Shared library support for UNIX using GNU libtool.
1034 * Modified backend interface. Request/Response struct's replaced by
1035 one read/write C struct. For example bend_fetchrequest and
1036 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1037 Every handler - even search has to be registered in bend_init
1038 handler. This means that the YAZ library no longer refers to
1039 external functions and it makes it possible to make the whole
1040 thing a single DLL/SO.
1042 Added Segment handler for backend server.
1044 Added Zmbol/Zebra administrative functions to YAZ client.
1046 Threaded frontend server on UNIX (when POSIX Threads are available).
1047 Starting the server with option -T enables multi-threading.
1051 Added configure option --enable-comp/disable-comp to control use
1052 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1053 located in sub directory asn.
1055 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1056 in ${exec_prefix}/bin along with the other programs yaz-client and
1059 GNU automake used to maintain makefiles.
1061 Added several OID's.
1063 Changed retrieval module so that we can load records with no abstract
1064 syntax defined. Tagpaths in these records are fully composed of string
1067 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1071 On UNIX, the generated makefile now supports a proper 'make install'.
1072 The prefix can be set via GNU configure to set the install location
1073 (default is /usr/local).
1075 * YAZ programs client and ztest were renamed to yaz-client and
1076 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1077 locations, such as /usr/bin,/usr/local/bin,etc.
1079 * YAZ Header files were moved from include to include/yaz. YAZ Header
1080 files are referred to as include <yaz/log.h> rather than <log.h>.
1081 The YAZ include path (-I ..) is therefore the same as before. Programmers
1082 should update their #include statements or use -Ipath/include/yaz
1083 instead. The main motivation for doing this change is that YAZ header files
1084 can be installed in "standard" locations /usr/include,/usr/local/include
1085 without introducing conflicts, since ALL YAZ header files are stored
1086 in subdirectory yaz (under /usr/include for example).
1088 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1089 rather than project/workspace files. We switched because project files
1090 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1093 Changed name of logging function, logf, to yaz_log, to prevent name
1094 clash with some math-log functions. The YAZ header log.h defines logf
1095 to yaz_log (#define) so there should be no incompatibilities by this
1098 Added bend_start/bend_stop handlers for server. These handler are
1099 called on start/stop of server. For windows they are called whenever
1100 a service is started/stopped.
1102 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1103 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1104 in util/yc.tcl. The auto-generated C code structures are, in a few
1105 cases, incompatible with the old decoders. There are differences in the
1106 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1107 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1108 The preprocessor variable ASN_COMPILED is defined when the compiled
1109 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1110 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1111 wish to use the old encoders/decoders you can specify --disable-yc
1114 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1115 version so that it supports both new - and old version of DB Update
1117 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1118 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1119 change. The name parameter can be set to 0 in which no name is specified
1120 for the construction. The macros odr_implicit and odr_explicit sets name
1121 parameter to zero for the construction involved. New macros
1122 odr_implicit_tag and odr_explicit_tag are similar to the others,
1123 except that a name parameter is added. For programmers' that don't use
1124 ODR they probably only need to change the call to z_APDU and z_External.
1126 Added access control facility by interfacing the TCP wrapper library.
1127 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1128 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1129 name of the daemon and enables the access control as specified in
1130 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1132 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1133 den Dool <H.M.vdnDool@kub.nl>.
1135 Added reference ID parameter to most functions in server API - refer
1136 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1138 Changed name of ccl library to libccl.a (was ccl.a).
1140 Fixed bug in decoder for Explain (Category TargetInfo).
1142 Added support for GNU readline in client. Thanks to Jacob Poulsen
1143 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1145 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1146 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1147 IMPLEMENTATION! This change was made to the development version before
1148 the ZIG decided to retract the amendment. If any users MUST be
1149 compatible with the original Update definition, PLEASE CONTACT US, and
1150 we will include a separate definition corresponding to the old Update
1151 ES. Note that because of the change to the ASN.1 of the
1152 TaskPackageRecordStructure we cannot define a single structure that
1153 will support both versions.
1155 * Added const modifier to buffer parameter for some ODR/BER encoding
1156 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1157 completeWAIS, odr_dumpBER.
1159 Fixed bug in client.c which caused a crash when a scanResponse didn't
1160 contain positionOfTerm.
1162 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1163 * will cause an error in a client if a non-YAZ target sends both a
1164 * list of Scan entries and non-surrogate diagnostics.
1166 Retrieval module enhancements. Tag sets may be typed in the reference
1167 to it. From the .abs-file the "tagset" directive takes a third optional
1168 integer type for the tag set referenced. From a .tag-file the "include"
1169 directive takes a third optional type as well. The old "type" directive
1170 in the tag set itself is still recognized but acts as the default type
1173 Backend interface change. Individual Scan terms returned from bend_scan
1174 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1175 in include/backend.h.
1177 Retrieval module enhancements. Multiple tag sets and attribute sets may
1178 be specified in abstract syntax specs. Revised the error/warning for
1179 logging messages reported by the retrieval module when reading the
1182 Object Identifier system (oid_..) changed. The API is backwards
1183 compatible but the oid-routines now allocates new OID's when needed.
1184 Raw OID's may be specified in oid_getvalbyname.
1186 YAZ now uses GNU configure to generate Makefile(s).
1188 * Minor changes in some of the member names of DeleteResultSetRequest and
1189 DeleteResultSetResponse. See include/proto.h.
1191 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1192 and added member 'languages' in TargetInfo (which was missing).
1194 Changed the way attribute sets are handled in the retrieval
1195 module. These are now cached, just like the abstract syntaxes
1198 Changed YAZ so that it links with compiled ASN.1.
1200 Added Explain-schema definitions and mapping routines. The following
1201 Explain categories have been implemented: AttributeDetails,
1202 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1204 Fixed minor bug in Windows version of Server Library.
1206 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1208 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1210 Added EXTERNAL: UNIverse Resource Report (non-standard).
1212 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1213 ENUMERATED and SET OF.
1215 * Added 'const' to some of the char pointer arguments for the
1216 functions, data1_read_node, data1_getelementbytagname,
1217 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1220 Fixed bug in data1_insert_taggeddata - the last_child member of
1221 parent wasn't initialised.
1223 * Changed data1_read_record and data1_read_node so that the supplied
1224 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1225 doesn't refer to any parts of the "SGML"-buffer.
1227 Fixed bug in server library (Windows version of statserv_remove).
1229 * Changed code so that it compiles as C++. The type definition
1230 of Odr_fun which is a member of Odr_arm was changed. The result is,
1231 that an explicit typecast is needed for the fun pointer when
1232 using Odr_arm - as in:
1233 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1235 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1237 Implemented the new structured date and time definition as approved
1238 by the ZIG. Added schemaId element to the specificTag in Espec-1
1239 (also approved at the last ZIG). Thanks to RVDM.
1241 Added some Object identifiers (RVDM).
1243 Changed the Update Extended Service (RVDM).
1245 Added command "refid" to client which specifies referenceId for
1246 the following requests.
1248 Implemented extended service handling for server. See ztest.c
1249 for an example as well as backend.h. New handlers are registerd
1250 in the Init handler.
1252 * Changed interface for sort in server.
1254 Added new members to statserv_options_block. It allows a server
1255 to read options from another source than just the command line. Thanks
1256 to Charles Woodfield.
1258 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1259 renamed to zboolean. Some C++ compilers complained about the name.
1261 Minor changes to gils.abs. Added index 's' (sort) on title
1262 and date/time-last-modified.
1264 --- 1.4pl2 1998/1/30
1266 Fixed bug in server library regarding inetd mode (-i). This bug
1267 was introduced by release 1.4.
1269 --- 1.4pl1 1998/1/29
1271 Added sort facility in client and backend server interface.
1273 Fixed problem with dependencies in Makefile(s).
1275 Fixed bugs for encoders/decoders of extended services and
1278 Implemented sub-tree feature for schemas. Sub-trees are
1279 referenced in *.abs-files. See explain.abs for an example
1280 of the use of this feature.
1282 Modified bib1.att; local attributes for ANY didn't include
1283 ANY itself (only affects use of the retrieval module).
1285 Fixed bug in plain SGML reader in function data1_read_node:
1286 tags with prefix "var" was incorrectly interpreted as variants.
1288 Added feature "sub-schemas" to enable references to - and definitions
1289 of - group of elements.
1291 * Removed member parent from type data1_element (in data1.h).
1293 Implemented function odr_nullval() that returns the value of
1296 * Removed member num_children from data1_node (in data1.h).
1298 Made NT service interface part of the server library. The
1299 function statserv_main uses the NT service when required and
1300 calls the statserv_start / statserv_close routines.
1302 Routine zget_SearchRequest and zget_PresentRequest fills
1303 resultSetName/Id member with "default" instead of "Default".
1305 Fixed memory leak in server. Request queue member wasn't freed.
1307 Fixed nmem_exit so that memory is freed.
1311 Revised the CCL parser utility to be thread safe.
1313 Added function, oid_ent_to_oid, to replace the function
1314 oid_getoidbyent, which is not thread safe.
1316 * Added nmem_init and nmem_exit to initialize and release
1317 NMEM resources. Function nmem_init should be called once in the
1318 initial thread before NMEM/ODR is used. statserv.c and client.c
1319 have been changed accordingly. The change was necessary to make
1320 NMEM thread safe. The NMEM memory pool is shared amongst threads
1321 in a process. Unix-based applications will still work fine without
1324 Added NT Services interface for the the Z39.50 (statserv) Server.
1325 Refer to the ztest.c source on the usage.
1327 Windows 95/NT port using MSVC5.0. Project files are included in the
1330 * Defined new 'global' handle for the retrieval (data1) system. The
1331 new handled, data1_handle, describes the state of the data1 system.
1332 This handle is passed as first argument to virtually all
1333 data1 related routines. The functions data1_create and data1_destroy
1334 creates and destroys a data1 handle respectively.
1336 Added ODR encode stream member to all backend request structures
1337 init, search, scan etc. This stream should be used to allocate all
1338 memory used for the response when thread safe operation is needed.
1340 Changed the comstack utility, cs_addstr, to be thread safe. The
1341 returned hostname string returned by the function is now part the
1344 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1345 function. The cs_straddr takes a COMSTACK handle as argument, so this
1346 function must be used after cs_create and before bind/connect.
1347 This function is thread safe.
1349 Moved test server to 'ztest' directory - generic server code still
1350 in 'server' directory.
1352 Made prefix query (pquery.c) utility thread safe.
1354 Added new function modifier YAZ_EXPORT to 'export' public DLL
1355 functions when using windows (see include/yconfig.h).
1357 Added definitions to the OID database (util/oid.c) (RVDM).
1359 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1361 Added call to ccl_rpn_delete in client program.
1363 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1364 release of RPN structure.
1366 Added support for C++, headers uses extern "C" for public definitions.
1367 With input from RVDM.
1369 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1370 Thanks to Ronald van der Meer (RVDM).
1372 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1374 Added support for private extensions to the OID database
1375 (oid_setprivateoids()). Thanks to RVDM.
1377 Added optional, physical ANY (key replication)
1379 Fixed null-reference problem in GRS-1 output filter.
1381 Proximity operator added to Prefix Query Format (PQF).
1383 In test client command "base" accepts multiple databases.
1385 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1389 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1391 Smallish bug-fixes in the new encoders/decoders (explain).
1393 Bug fixed in DeleteRequest.
1395 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1397 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1399 Added SOIF syntax (using private OID for now) to retrieval module and client.
1401 Added Update extended service.
1403 Added SearchResult-1 additional info structure.
1405 Added optional CCL (ISO8777) interpreter as separate module. Available
1408 --- 1.2 1996/6/10 (1st anniversary release)
1410 Added Summary record syntax. Lightly tested.
1412 Added OPAC record syntax. Untested.
1414 Added ResourceReport service encoders/decoders. Untested.
1416 Fixed bug in z_Unit - wrong tagging on unitSystem.
1418 Fixed bug in the DiagRecs decoder.
1420 Added options for max PDU size and session timeout to frontend-server.
1422 Added documentation of query-language parsers and other supporting utilities.
1424 [frontend-server] Added Attribute set to the bend_scanrequest API.
1426 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1427 surrogate diagnostics were generated.
1429 [retrieval] Allow multiple local values for attribute.
1431 [retrieval] Allow multiple attributes per element in .abs files. index type.
1433 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1435 --- 1.1pl2 1996/4/10
1437 Minor changes, mostly specific to Zebra's requirements (retrieval)
1441 Repaired bug in frontend server when running multiple listening
1442 endpoints in dynamic mode.
1444 z_External() now won't break if a known, ASN.1 value comes encapsulated
1445 in an octet-string. The value will pass through unmodified in an Odr_oct.
1447 Added a bit of code to the demo client to decode & display
1448 ASN.1-structured records represented in the octet-aligned branch of
1449 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1451 Added z_ext_getentbyref() to the ASN module. Doc updated.
1453 * Completed the SCAN definition in the ASN module. This may break SCAN
1454 code based on older YAZ-versions at compile-time. The fix is easy -
1457 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1458 under the SCAN definition. Remember to initialize this, server-people.
1460 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1461 that this does not extend to ODR and ASN.
1463 Comstack allows insertion of established socket (primarily for
1464 inetd-operation of servers). Doc updated.
1466 Front-end server can now start from the inetd in TCP mode. Doc
1469 --- 1.0pl4 1996/1/24
1473 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1474 the rank and record number.
1476 Adjustments to the frontend server.
1478 Fixed diagnostic BER dumper. It ignored the file argument.
1482 Various changes to retrieval module.
1484 Changed the union discriminators of the protocol files from enums to
1485 ints paired with #defines.
1487 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1490 *Changed operator in the RPN structure to 'roperator', again to avoid a
1493 Fixed problems in Explain decoders/encoders.
1495 --- 1.0pl2 1995/12/6
1497 Memory bug in log module fixed.
1499 --- 1.0pl1 1995/12/5
1501 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1503 Bug in Explain DatabaseInfo module fixed.
1505 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1509 The shift to v1.0 signals that we now consider the *core* functionality
1510 of YAZ reasonably stable (the core being more or less equivalent to
1511 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1512 tested (Explain not at all - though that will happen soonish).
1514 Minor changes to code to support Windows port.
1516 Various minor changes after we're getting to use GRS-1 & co. more.
1518 Added Espec-1 format.
1520 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1521 of the protocol and it cannot be selected when encoding (maps into 'string'
1522 when decoding). Needed to talk to some servers.
1524 Demo client can request simple element set names.
1526 Added Diagnostic Format encoders/decoders.
1528 Added simple Close handling to frontend server (no hooks for resource
1529 reporting yet), and demonstration client.
1531 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1533 --- 1.0b3 1995/08/24
1535 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1536 handled incorrectly when records were requested in the searchResponse. This
1537 will only affect you if you use the frontend-server.
1539 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1540 Test-client will ask for and print GRS1. Ztest will return dummy records
1543 Added Explain encoders/decoders to the service-level API. Untested.
1545 Added Extended Services: Item Order encoders and decoders to the Service-
1546 level API. Untested. We could use a recent copy of the pertinent bits
1547 of the ILL protocol to add those bits.
1549 Added diagnostic format 1 encoders/decoders to the service-level API.
1552 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1553 odr_cons.c, which causes a more correct output.
1555 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1556 was always set to 0 when no records were requested in the searchRequest.
1558 * Added better external-handling. This shouldn't harm old code that
1559 *encodes* externals. It can break code that looks for a
1560 'single-ASN1-type' representation, since those types that are known
1561 are now decoded immediately. Look at the SUTRS sample code in
1562 seshigh.c and client.c. Documentation updated.
1564 Handling of structured records in bend_fetchresponse. Length -1 marks
1565 structured record, type is deduced from format field.
1567 --- 1.0b2 1995/06/27
1568 Fairly quick maintenance release to add SUTRS support.
1570 Fixed handling of SUTRS records in the demonstration client.
1572 * Added format field to the bend_fetchrequest and bend_fetchresponce
1573 structures of the backend API (frontend server). When the record is
1574 returned, the value of the format field is mapped to an OID. The
1575 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1576 of the record. The special value VAL_NONE in the bend_request means
1577 that no specific format was requested by the client. Documentation
1578 updated accordingly. Test server (ztest) will return a fixed dummy
1579 SUTRS record if your client requests SUTRS.
1581 Documentation updated accordingly.
1583 You can now set external libraries and RANLIB support in the top-level
1587 First public release.
