1 Possible compatibility problems with earlier versions marked with '*'.
3 Fixed bug #272: Preserve spacing for CCL terms.
7 Added support for virtual hosts and multiple backend servers for
8 the YAZ frontend server. The configution is XML based and
9 support specificition of CQL to RPN mappings and explain information.
10 See section "Virtual Hosts" in the YAZ manual.
12 Extended OPAC display utility. OPAC display utility renders
13 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
14 to supplement yaz_marc_decode_wrbuf.
16 Fixed a bug in MARC decoder that could caused it to crash for some
17 invalid MARC records. More diagnostics and warnings where added in
18 XML output (warnings, etc are stored in comments).
22 Fixes for UNIX domain sockets. Bug #261.
24 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
26 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
27 Added yaz_marc_subfield_str which defines subfield lead string which is
28 used in YAZ_MARC_LINE format. Default string is blank+$. Added
29 yaz_marc_endline_str which defines end of fields string used in
30 YAZ_MARC_LINE format. Default string is newline.
32 Experimental support for MarcXChange. This format can be produced
33 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
34 http://www.bs.dk/standards/MarcXchange.xsd
36 Added yaz-client commands scansize that sets maximum number of
37 entries to be returned by scan.
41 Added support for SRW scan in yaz-client and Generic Frontend Server.
43 * Added whereInList member to SRW Scan Term.
45 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
47 Fixed NMEM system to return aligned blocks on the smallest boundaries
48 that are suitably aligned for all possible types on the particular
49 architecture YAZ is being built for.
53 Fixed numerious warnings that was issued with newer versions of GCC.
55 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
56 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
59 Make YAZ Generic Frontend Server slightly faster.
61 Enhance (and reduce) logging for Generic Frontend Server.
63 Revert YAZ log system so that it flushes every write operation
64 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
66 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
67 instead of LOG_, due to name clash with syslog(3). LOG_ are still
68 present. New applications should define YAZ_USE_NEW_LOG=1 - this
69 will effectively disable old definitions.
73 Added yaz_log_time_format which specifies log format using
76 Added yaz_log_module_level which returns mask for a module. Value
77 is non-zero mask a if module is enabled; zero if disabled.
79 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
82 Fixed bug #176: Dont throw diagnostics on empty SRU args.
84 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
86 Fixed bug #172: RPM builds does not enable SSL.
88 Doxyfile.in part of dist. Doxyfile generated by configure.
90 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
91 are given and the corresponding component does not exist.
93 Extend CCL documentation in YAZ reference. Describe r=r.
97 Fixed MARC->MARCXML conversion to properly deal with
98 fields, subfields, indicators having non-ASCII characters.
100 Fixed MARC->MARCXML conversion so that ASCII control characters
101 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
104 Added YAZ GFS support for conversion from Z39.50 surrogate
105 diagnostics to SRW surrogate diagnostics.
107 Bug fix: YAZ GFS did not return schema in explainResponse.
109 --- 2.0.25 2004/09/30
111 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
112 now converts recordSchema to elementSetName as well as schema URI.
114 Fixed bug in COMSTACK that prevented HTTP request packages from being
117 --- 2.0.24 2004/09/29
119 Added CCL facility r=r "range" which is similar to r=o "ordered" but
120 does not require white-space before and after the dash in a range, e.g.
121 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
124 Fixed a few AC_TRY_LINK configure tests that did not operate properly
125 due to new GCC removing "redundant" code.
127 Added yaz-client commands scanpos and scanstep that sets preferred
128 position and step-size for scan.
130 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
132 Added CCL utility ccl_qual_buf which parses one or more CCL
133 spec lines in a buffer.
135 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
136 of name and value - ignoring empty lines and comments.
138 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
140 Added odr_get_element_path which returns current element path for an
141 ODR handle. This utility is useful in error handling or user-defined
144 Added ODR_PRINT utility odr_set_stream which is is a more generic
145 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
146 to a write function and pointer to close function. The close function - if
147 non-NULL - will be called during odr_destroy.
149 Fixed bug in CCL parser where truncation char was not removed from
150 right side when truncation=both was in effect.
152 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
155 --- 2.0.23 2004/08/11
157 Fix buffer overrun in CQL parser when dealing with proximity (%).
159 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
160 to UTF-8/UCS conversion is now only based on codetables.xml.
162 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
164 --- 2.0.22 2004/08/06
166 Add support for more "commit changes" in ZOOM (uses Extended Services).
168 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
171 Yet another small fix for configure of SSL.
173 --- 2.0.21 2004/05/14
175 Fix SSL libs for configure when --with-openssl=DIR is given.
177 --- 2.0.20 2004/05/10
179 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
181 SSL comstack now uses yaz.pem certificate file on server side
182 by default. Certificate filename can be configured by calling
183 comstack function cs_set_ssl_certificate_file before cs_bind is used.
185 Fix bug regarding multiple calls to ZOOM_connection_connect.
187 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
189 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
190 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
192 ZOOM now allows inspection of X509 peer certificate for verification.
193 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
195 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
196 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
197 as "modular" but it simplifies things.
199 Added cs_get_peer_certificate to that returns peer X509 PEM.
201 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
202 NULL if SSL is unavailable.
204 Documentation about MARC decoding tools.
206 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
208 --- 2.0.19 2004/03/30
210 Rename CHANGELOG to NEWS to follow GNU style packing.
212 Fix bug with missing initialization of member in init_diagnostics.
213 This bug affects threaded version of GFS server.
215 --- 2.0.18 2004/03/20
217 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
220 Ensure zlib.dll is packed with Windows install.
222 --- 2.0.17 2004/03/17
224 Fix encoding of xsd:string to use text instead of CDATA.
226 Fix endless loop in CQL parser with unbalanced ".
228 Use a more compact way to store MARC-8 conversion tables.
230 --- 2.0.16 2004/03/16 Debian only
232 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
235 Update CQL parser to use new CQL 1.1 modifiers for booleans and
240 --- 2.0.15 2004/03/01
242 Another fix for decoding of XML packed records.
244 --- 2.0.14 2004/02/25
246 Fixes for Chunked encoding. White space not ignored after length spec.
248 Update NS and use default NS for SRW diagnostic elements.
250 --- 2.0.13 2004/02/23
252 Implement ZOOM_resultset_cache_reset which resets record cache.
254 Implement ZOOM_resultset_sort which sorts a result set.
256 Implement chunked HTTP transfer.
258 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
260 --- 2.0.12 2004/02/16
262 Added member 'schema' to bend_explain_rr structure so that backend
263 can specify explain record identifier. Defaults to Zeerex 2.0.
265 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
267 --- 2.0.11 2004/02/16
269 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
272 Added init command for yaz-client which sends "extra" init request.
274 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
275 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
277 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
279 Make ZOOM error code for "invalid query".
281 Fixed compilation for SSL which wasn't properly enabled for all platforms.
283 --- 2.0.10 2004/02/05
285 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
288 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
290 Added option -p <file> to make Generic Frontend Server to write PID file.
292 Added option -D to put Generic Frontend Server in background on its own.
294 Make ZOOM C recognize option "password". If unset, "pass" is used
295 (for backwards compatibility).
297 Fixed a bug in Generic Frontend Server that could make it crash if a
298 client sets characterSetNegotation bit, but didn't pass negotiation stuff
301 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
302 Must be issued before open, in order to be in effect.
304 --- 2.0.9-6 2004/01/12 Debian/Windows
306 Make the SRU server more picky WRT unknown params, etc.
308 Bug fix: ZOOM scan response didn't return displayTerm - when present.
310 New YAZ client command, options, that sets Z39.50 options.
312 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
313 options from a string of tokens (one token for each option bit).
315 Update SRW diagnostic code messages.
317 --- 2.0.9-5 2004/01/07 Debian/Windows
319 Handle user defined stylesheet for SRW/SRU.
321 --- 2.0.9-4 2004/01/06 Debian/Windows
323 Fix bug in decoding of Content-Length.
325 --- 2.0.9-3 2004/01/06 Debian/Windows
327 Fix a bug with decoding of XML packed records.
329 --- 2.0.9-2 2004/01/05 Debian only
331 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
333 Fix bug in SRW/SRU diagnostics decoding.
337 Fixed bug in Generic Frontend Server which could drop records exceeding
338 preferred message size. Reported and fixed by Irina Dijour.
340 Fixed calculation of package size for structured records in Generic
341 Frontend Server. Reported and fixed by Irina Dijour.
343 Fixed namespace for SRW/SRU diagnostics.
345 Fixed SEGV in yaz-client that occured for HTTP connection errors.
349 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
350 this version is incompatible with version 1.0 and older YAZ SRW/SRU
353 CQL changes to reflect recent changes to the specification:
354 * Documentation talks about context sets instead of index sets.
355 * Documentation talks about indexes instead of qualifiers.
356 * The CQL-to-PQF transformer's configuration file now uses
357 "index.set.name = <attributes>" instead of the old form
358 "qualifier.set.name = <attributes>". (Both forms are still
359 understood but the latter is deprecated.)
360 * CQL terms with no explicit index specified are now interpreted as
361 cql.serverChoice instead of srw.serverChoice (which of course
362 behaves exactly the same.)
366 MARC conversion can now generate ISO2709 output in another
367 character set. yaz-marcdump uses this facility if you invoke it
370 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
371 functions from there can be used from C++.
375 Frontend server now transfers memory from decoded packages to stream
378 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
379 references to show up.
381 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
382 the ZOOM Abstract API. The older names for the same options are still
383 also supported for the benefit of old applications.
385 ZOOM-C supports "implementationId" and "implementationVersion" options
386 to go along with "implementationName". These allow the user code to
387 specify identification strings to be sent to servers.
388 Add OID for the new ExtLite attribute set.
390 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
391 as requested/supplid by Ere Maijala <ere@atp.fi>
393 For generic frontend server, reverse the order of
394 "toolkit-supplied / application-supplied" strings sent as implementationId,
395 Name and Version. Also, remove the spaces around the slash. This brings
396 the GFS in line with the behaviour of ZOOM-C on the client side.
398 Add function ZOOM_scanset_display_term.
400 yaz-client shows scan displayTerm if present.
402 Utility yaz-iconv is now installed by default along with the man page
405 Extend configure check for OpenSSL to use pkg-config where available (such
408 Incorporate patch by Morten Bogeskov which allows a Unix file socket
409 server to specify uid/gid/mask for socket using the format
410 unix:[user=uid,][group=gid,][umask=mask,]file=path
411 If file= is omitted the existing format is assumed, e.g.
413 in which case the mask is 0666 (rw for everybody).
415 Major restructure of YAZ source. All source in libyaz is in src directory.
416 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
417 util (utility programs such as ASN.1 compiler, yaz-marcdump).
419 Added man page for utility yaz-marcdump (used to be called marcdump).
420 yaz-marcdump is installed by 'make install'.
422 Fixed a memory leak in Generic Frontend Server that occurred when decoding
423 of incoming package failed.
425 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
427 Change prototype of odr_perror: add const to message string.
429 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
431 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
432 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
433 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
434 DNS lookup. There should not be any compatibility problems with this
435 assuming that blocking=1 or 0 is used.
437 Fix bad reference in UNIX comstack in function cs_addrstr.
439 Fix for compilation on AIX.
441 The generic front-end server (server/seshigh.c) now supports returning
442 Init diagnostics to the client in User-information-field, in
443 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
448 Allow any CQL relation (not just all,any,exact,scr).
450 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
451 that features the same UI.
453 Implemented command update0 in YAZ client which is equivalent to
454 update but uses old of Ext Update ASN.1.
456 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
457 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
458 Previously no OID was used for this info.
460 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
461 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
462 returns 'malformed search term' otherwise.
464 SortResponse member resultCount now set to NULL in sort handler of
467 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
470 Add three new utility functions for translating OIDs between various
471 formats -- symbolic name such as "Usmarc", minus-1-terminated int
472 arrays and dotted strings such as "1.2.840.10003.9.5.1":
473 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
474 char *oid_to_dotstring(const int *oid, char *oidbuf);
475 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
477 Reverted modifications for ES Update definition for z_IU0Update
478 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
479 is back to YAZ 2.0.2.
481 String value attributes for CCL parser.
483 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
484 which their FirstSearch server returns in Init responses, sometimes
485 carrying useful diagnostic information when Init fails. This has the
486 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
487 "z39.50/oclcui.asn", where its definition is somewhat different from
488 what OCLC document on their web-site, as required to interoperate with
491 Support for anonymous authentication in yaz-client. Use the command
494 * Fix the OID of the Index Data-local "admin" Extended Service from
495 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
496 the 1000, which indicates a locally-defined OID, was a mistake.
500 Fix CCL directive @case handling so that it affects string match for
501 both CCL keywords and qualifiers.
503 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
504 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
505 Decoder has been updated with ASN.1 changes as listed in
506 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
507 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
508 z_IUUpdate, remains unchanged.
510 ZOOM_record_get may now return a record in a specific character set.
511 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
512 "from" is the character set of record as returned by target. "to" is
513 the character set to be returned. If omitted, "to" is UTF-8.
515 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
517 New ODR utility, odr_getelement, which returns name of element for
518 which encoding/decoding failed.
520 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
521 in cases where a required element was omitted.
523 Bug fix: some MARC8 sequences were not converted.
525 New ZOOM option "step" which specifies number of records to be
526 retrieved in one chunk. Used in conjunction with "start" and "count".
528 SRW support for yaz-client. Use scheme http: to use it, e.g.
531 yaz-client no longer does (un)intelligent character set conversions
532 by default. Can be enabled with charset and marc_charset commands.
534 xmalloc trace fix for 64-bit systems such as DEC alpha.
536 Solaris 2.6 compile fix.
538 New function, cql_strerror() translates SRW error codes, as returned
539 by cql_transform_error(), into human-readable English strings. Used
540 in yaz-client diagnostics when appropriate.
542 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
543 converts it into a type-1 query which is sent to the server. This
544 makes CQL available for use with all Z-servers, as opposed to the tiny
545 minority that can handle CQL queries themselves.
549 New Debian package layout similar to the Redhat Package layout.
551 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
552 and search result respectively.
556 Redhat package is now several packages: libyaz (runtime libraries),
557 libyaz-devel (development and documentation, and yaz (utility programs).
558 Package spec file by Morten Bøgeskov.
560 New member 'schema' in struct bend_fetch_rr which the name of requested
561 schema (SRW/SRU) for record (or NULL if none was given). The fetch
562 handler MAY set this to reflect the schema of the returned record.
564 New member 'display_term' in struct scan_entry. GFS now sets member entries
565 and allocates scan entries to be filled by user scan handler. In previous
566 version, entries member was allocated by the scan handler. That still works,
567 but the GFS will ignore member display_term - assuming it was NOT set by
568 the handler. The fact that the GFS now allocates the entries both allows
569 for new members and makes a scan handler easier to write.
571 Fix CQL lex buffer overflow.
573 SRW/SRU recordPacking. For SRW default recordPacking is string. For
574 SRU default recordPacking is string.
576 SRU protocol support for frontend server.
578 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
580 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
582 Added scan for the ZOOM shell (zoomsh).
586 * String Identifers for Schemas (Amendment 5).
587 http://lcweb.loc.gov/z3950/agency/amend/am5.html
588 Old definition for schema
589 Odr_oid *schema; /* OPT */
594 Z_InternationalString *uri;
595 #define Z_Schema_oid 1
596 #define Z_Schema_uri 2
599 * resultCount parameter to Sort Response (Amendment 1).
600 http://lcweb.loc.gov/z3950/agency/amend/am1.html
602 Support for SRW 1.0 over HTTP. This is an optional feature and
603 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
606 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
607 on the same port. SRW SearchRetrieveRequests are mapped
608 to bend_init,bend_search,bend_fetch,bend_close.
610 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
612 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
613 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
615 ZOOM connections are SRW based if schem http is used for hostname
616 in connect, e.g. z = ZOOM_connection_new("http://myserver");
617 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
619 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
620 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
621 distance=n, order=true/false, relation=le, prox unit=word. If
622 n is omitted, distance 1 is used.
624 Fixed problem with C compiler include path in wrong order.
626 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
627 on Solaris. Patch from Ko van der Sloot.
629 New MARC decode API. All new functions operate on a yaz_marc_t
630 handle. The most important new functions are: yaz_marc_create,
631 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
632 decode and destroy respectively. Decoder can produce formats
633 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
634 include/yaz/marcdisp.h.
636 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
637 to UTF-8, UCS-32, wchar_t or Latin-1.
639 * Prototypes for yaz_iconv_-functions moved to separate header
640 include/yaz/yaz-iconv.h.
642 Make a few private functions 'static' in unix.c. This prevents
643 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
645 For ZOOM connection, the options targetImplementation{Id,Name,Version}
646 are set when Init Response is received.
648 New function ZOOM_connection_error_x similar to ZOOM_connection_error
649 but returns diagnostic set as well.
651 New function yaz_strerror which is a portable wrapper for
652 strerror/strerror_r/GetLastMessage.
654 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
655 is returned for MARC. If type is "oai", then OAI MARC is returned.
657 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
662 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
664 Fix bad race conditions on SIGTERM and terminate gracefully in
667 Move retrieval (data1) module to Zebra since nobody seems to be
670 Add GRS-1 render for ZOOM using same format as yaz-client.
674 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
676 Fix broken ESpec handling in data1 module.
678 SGML reader parses comments and makes them part of the data1 tree.
680 Added several type casts so that YAZ compiles as C++ code.
682 ZOOM didn't handle PDU encoding failures properly.
684 Added more Bib-1 diagnostics (approved extensions).
686 GNU configure: better check for iconv.
688 More portable use of accept, getpeername. Check for socklen_t. Use
689 int/size_t if socklen_t is not defined.
693 PQF parser rejects bad queries - including those with extra
694 characters in them. PQF parser used to silently ignore that.
695 Cleaner API for PQF added, which allows you to get detailed
696 error information for bad queries (see yaz/pquery.h).
698 Fixed bug in ZOOM_record_get for type "database".
700 Implemented mini iconv library supporting conversions between
701 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
703 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
707 Fixed ZOOM C record cache so that preferredRecordSyntax and
708 elementSetName is used to check for already fetched records.
712 Added three members in bend_initrequest structure to facilitate
713 character set negotiation.
715 Fixed a bug in frontend server that could cause indefinite
716 loops under rare conditions.
718 Revised character set utilities (charneg.h) so that encoding
719 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
721 For PQF, directive @term <type> sets term type for Scan/Search.
722 Here <type> is general, string, numeric, null. The term type
723 is inherited - just like @attr.
725 New call odr_set_charset that sets character set conversion for
726 international-strings on a ODR stream. Prototype is:
727 int odr_set_charset(ODR o, const char *to, const char *from);
728 The InternationalString is still represented as C string in YAZ
729 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
730 won't). On the protocol level, you can use any encoding.
732 Support for UNIX sockets in ZOOM.
734 Solaris recv sometimes returns errno == ENOENT. It is treated as
735 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
737 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
738 both client and server. Code by Morten Bøgeskov.
742 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
743 that they can be used directly from Visual Basic. You must recompile
744 your windows APP if you're using ZOOM.
746 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
747 Commands "lang" and "charset" sets language and character set respectively.
748 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
749 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
751 Attributes from multiple CCL fields may be OR'ed rather than merged
752 using directive "@field or". Fields are still merged by default -
753 equivalent to "@field merge".
755 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
758 Fixed bug in zget for parameter ExtendedServicesResponse.
764 Added PQF feature: '@attr type=value' may be written as '@type=value'.
766 Client displays USR.1:SearchResult-1 (hits per term).
768 Additional Search Info for search in Generic Frontend Server.
770 Fixed CCL parsing of "field=s".
772 WIN32 installer - using the excellent NSIS software from nullsoft.
774 Fixed CCL parsing of "field = - <number>".
776 Added function yaz_marc_decode that decodes MARC for line mode
777 display or XML (similar to that used by JZKit).
779 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
780 Z39.50. But ISO/ILL was, however.
782 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
783 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
785 http://lcweb.loc.gov/z3950/agency/amend/am2.html
786 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
790 New YAZ client features: Command completion and new commands:
791 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
792 Code provided by Jacob Poulsen.
794 New call oid_trav, that visits all registered OIDs via callback.
796 Function ZOOM_record_get now returns const char pointer rather than
797 void pointer. It saves a lot of type casts.
799 For YAZ client, command "auth" now allows you to set authentication
800 in IdPass style. It is enabled when three tokens are given - order
801 is user, group and password.
803 Fix memory leaks in MARC record handling for ZOOM.
805 New option for YAZ client, -k <kilobytes> that sets
806 maximum record size. Similar to -k option for generic frontend
807 server and yaz-ztest.
809 More fixes for scan. Non-zero stepSize handled. OID's fixes.
811 Prefix query parser reports "fail" when bad attribute set is given.
813 Fix in MARC decoder. Proximity logging. Fix for attribute set
814 in scan handler for server. Patches by Shigeru Ishida.
816 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
819 Configure option --with-openssl=<dir> now works when a directory is
820 specified. Patch provided by Morten Bøgeskov.
822 New option for YAZ client, -u <auth>, that sets authentication.
824 ZOOM fix: error information was sometimes "missing", since error
825 was cleared/reset too when it shouldn't.
827 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
831 Scan for ZOOM API. New object ZOOM_scanset. New functions
832 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
833 ZOOM_scanset_destroy.
835 New ZOOM function, ZOOM_connection_last_event, that returns type
836 of last event (such as "receive data", "send data", "apdu received",
839 New ZOOM option, schema, that specifies schema for retrieval.
841 New CCL feature. Qualifiers can be aliases for one or more
842 other qualifiers (if more than one is given, OR is used).
844 ZOOM uses named result sets if target supports it.
846 Two new YAZ client commands: . (dot, which sources a script of YAZ
847 client commands), and ! (to execute shell command.). Implemented
850 Working on Debian packages.
854 YAZ client enables named result sets only if target supports it.
856 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
858 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
859 with key="host" to get same result.
861 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
862 Function Z3950_resultset_record(s) returns references to records
863 "owned" by resultset. To become owner use Z3950_record_clone.
865 Function z_ext_record handles Extended Services. Thanks to
870 CCL Parser fix: ignore token comma when dealing with and-lists.
872 Documentation updates for COMSTACK.
874 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
875 Changed prototype Z3950_records. For some functions, int parameters
876 were changed to size_t.
878 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
881 New MARC decode/display function, marc_display_exl, which properly rejects
882 non-ISO2709 records. YAZ client uses it.
886 Fix bug: local attribute set wasn't set correctly in PQF strings.
890 * Old Z39.50 codecs no longer supported.
892 Added ZOOM C binding. See http://zoom.z3950.org/
894 Renamed states for COMSTACKs to avoid confusion with events.
896 Implemented cs_look and proper cs_rcvconnect.
898 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
900 Configure detects POSIX threads on OpenBSD.
902 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
903 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
905 When error is returned from present handler, non-surrogate diagnostic
906 is returned in present response (and fetch handler is no longer called).
908 * Minor adjustments to pquery parser (PQF). Token characters may be
909 escaped by using backslash (C-style).
911 PQF parser allows string attribute values to be specified. For @attr,
912 non-numeric characters after the equal-sign are treated as strings
913 (e.g. @attr 9=title).
915 CCL trunction character may be defined (@truncation in file)
917 * function zget_ExtendedServicesRequest sets waitAction to
918 waitIfPossible (was wait).
920 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
923 CCL operator names may be set in field definition files (CCL_bibset).
924 See ccl/bib1 for an example.
926 Fixes in ASN.1 compiler for C++ compatibility.
928 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
929 and "op_or" to avoid conflict with C++.
931 Fixed problem with GNU readline detection on Redhat 7.0.
933 Added step-size for Scan backend handler.
935 Fixed bug that made the frontend server crash when no attribute
936 set was specified for scan.
938 Front-end server automatically switches to original working directory
939 when installed as an NT service. Previously -w had to be specified to
942 Added extended attributes for retrieval module (data1), so that data1
943 records carry d1_readXML/SGML attributes. d1_read also supports
944 null-data rules ( <tag/>)
946 On UNIX when POSIX threads are available, a separate library libyazthread
947 is created. Programmers should link with that library and the yaz library
948 when using threads. The reason for the split was that some applications
949 on Linux, such as Apache, doesn't work well when using shared objects that
952 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
953 (or any frontend server) in SSL mode by specifying ssl: followed by
954 address. Only tested on UNIX.
956 Added feature for CCL module. Virtual structure s=al or s=ol generates
957 and-list and or-list respectively instead of phrase search.
961 * Added prefix "yaz_" for the functions log_init.., log_file.. and
962 log_mask_str. This was done to avoid name conflicts with other libraries
963 (such as other PHP extensions).
965 Added raw OID member for preferred record syntax (request_format_raw)
966 and returned record syntax (output_format_raw) for backend fetch method.
968 Config file yaz-config now accepts options so that it returns specific
969 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
971 Shared library support for UNIX using GNU libtool.
973 * Modified backend interface. Request/Response struct's replaced by
974 one read/write C struct. For example bend_fetchrequest and
975 bend_fetchresult have been replaced by single bend_fetch_rr struct.
976 Every handler - even search has to be registered in bend_init
977 handler. This means that the YAZ library no longer refers to
978 external functions and it makes it possible to make the whole
979 thing a single DLL/SO.
981 Added Segment handler for backend server.
983 Added Zmbol/Zebra administrative functions to YAZ client.
985 Threaded frontend server on UNIX (when POSIX Threads are available).
986 Starting the server with option -T enables multi-threading.
990 Added configure option --enable-comp/disable-comp to control use
991 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
992 located in sub directory asn.
994 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
995 in ${exec_prefix}/bin along with the other programs yaz-client and
998 GNU automake used to maintain makefiles.
1000 Added several OID's.
1002 Changed retrieval module so that we can load records with no abstract
1003 syntax defined. Tagpaths in these records are fully composed of string
1006 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1010 On UNIX, the generated makefile now supports a proper 'make install'.
1011 The prefix can be set via GNU configure to set the install location
1012 (default is /usr/local).
1014 * YAZ programs client and ztest were renamed to yaz-client and
1015 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1016 locations, such as /usr/bin,/usr/local/bin,etc.
1018 * YAZ Header files were moved from include to include/yaz. YAZ Header
1019 files are referred to as include <yaz/log.h> rather than <log.h>.
1020 The YAZ include path (-I ..) is therefore the same as before. Programmers
1021 should update their #include statements or use -Ipath/include/yaz
1022 instead. The main motivation for doing this change is that YAZ header files
1023 can be installed in "standard" locations /usr/include,/usr/local/include
1024 without introducing conflicts, since ALL YAZ header files are stored
1025 in subdirectory yaz (under /usr/include for example).
1027 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1028 rather than project/workspace files. We switched because project files
1029 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1032 Changed name of logging function, logf, to yaz_log, to prevent name
1033 clash with some math-log functions. The YAZ header log.h defines logf
1034 to yaz_log (#define) so there should be no incompatibilities by this
1037 Added bend_start/bend_stop handlers for server. These handler are
1038 called on start/stop of server. For windows they are called whenever
1039 a service is started/stopped.
1041 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1042 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1043 in util/yc.tcl. The auto-generated C code structures are, in a few
1044 cases, incompatible with the old decoders. There are differences in the
1045 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1046 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1047 The preprocessor variable ASN_COMPILED is defined when the compiled
1048 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1049 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1050 wish to use the old encoders/decoders you can specify --disable-yc
1053 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1054 version so that it supports both new - and old version of DB Update
1056 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1057 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1058 change. The name parameter can be set to 0 in which no name is specified
1059 for the construction. The macros odr_implicit and odr_explicit sets name
1060 parameter to zero for the construction involved. New macros
1061 odr_implicit_tag and odr_explicit_tag are similar to the others,
1062 except that a name parameter is added. For programmers' that don't use
1063 ODR they probably only need to change the call to z_APDU and z_External.
1065 Added access control facility by interfacing the TCP wrapper library.
1066 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1067 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1068 name of the daemon and enables the access control as specified in
1069 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1071 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1072 den Dool <H.M.vdnDool@kub.nl>.
1074 Added reference ID parameter to most functions in server API - refer
1075 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1077 Changed name of ccl library to libccl.a (was ccl.a).
1079 Fixed bug in decoder for Explain (Category TargetInfo).
1081 Added support for GNU readline in client. Thanks to Jacob Poulsen
1082 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1084 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1085 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1086 IMPLEMENTATION! This change was made to the development version before
1087 the ZIG decided to retract the amendment. If any users MUST be
1088 compatible with the original Update definition, PLEASE CONTACT US, and
1089 we will include a separate definition corresponding to the old Update
1090 ES. Note that because of the change to the ASN.1 of the
1091 TaskPackageRecordStructure we cannot define a single structure that
1092 will support both versions.
1094 * Added const modifier to buffer parameter for some ODR/BER encoding
1095 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1096 completeWAIS, odr_dumpBER.
1098 Fixed bug in client.c which caused a crash when a scanResponse didn't
1099 contain positionOfTerm.
1101 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1102 * will cause an error in a client if a non-YAZ target sends both a
1103 * list of Scan entries and non-surrogate diagnostics.
1105 Retrieval module enhancements. Tag sets may be typed in the reference
1106 to it. From the .abs-file the "tagset" directive takes a third optional
1107 integer type for the tag set referenced. From a .tag-file the "include"
1108 directive takes a third optional type as well. The old "type" directive
1109 in the tag set itself is still recognized but acts as the default type
1112 Backend interface change. Individual Scan terms returned from bend_scan
1113 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1114 in include/backend.h.
1116 Retrieval module enhancements. Multiple tag sets and attribute sets may
1117 be specified in abstract syntax specs. Revised the error/warning for
1118 logging messages reported by the retrieval module when reading the
1121 Object Identifier system (oid_..) changed. The API is backwards
1122 compatible but the oid-routines now allocates new OID's when needed.
1123 Raw OID's may be specified in oid_getvalbyname.
1125 YAZ now uses GNU configure to generate Makefile(s).
1127 * Minor changes in some of the member names of DeleteResultSetRequest and
1128 DeleteResultSetResponse. See include/proto.h.
1130 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1131 and added member 'languages' in TargetInfo (which was missing).
1133 Changed the way attribute sets are handled in the retrieval
1134 module. These are now cached, just like the abstract syntaxes
1137 Changed YAZ so that it links with compiled ASN.1.
1139 Added Explain-schema definitions and mapping routines. The following
1140 Explain categories have been implemented: AttributeDetails,
1141 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1143 Fixed minor bug in Windows version of Server Library.
1145 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1147 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1149 Added EXTERNAL: UNIverse Resource Report (non-standard).
1151 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1152 ENUMERATED and SET OF.
1154 * Added 'const' to some of the char pointer arguments for the
1155 functions, data1_read_node, data1_getelementbytagname,
1156 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1159 Fixed bug in data1_insert_taggeddata - the last_child member of
1160 parent wasn't initialised.
1162 * Changed data1_read_record and data1_read_node so that the supplied
1163 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1164 doesn't refer to any parts of the "SGML"-buffer.
1166 Fixed bug in server library (Windows version of statserv_remove).
1168 * Changed code so that it compiles as C++. The type definition
1169 of Odr_fun which is a member of Odr_arm was changed. The result is,
1170 that an explicit typecast is needed for the fun pointer when
1171 using Odr_arm - as in:
1172 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1174 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1176 Implemented the new structured date and time definition as approved
1177 by the ZIG. Added schemaId element to the specificTag in Espec-1
1178 (also approved at the last ZIG). Thanks to RVDM.
1180 Added some Object identifiers (RVDM).
1182 Changed the Update Extended Service (RVDM).
1184 Added command "refid" to client which specifies referenceId for
1185 the following requests.
1187 Implemented extended service handling for server. See ztest.c
1188 for an example as well as backend.h. New handlers are registerd
1189 in the Init handler.
1191 * Changed interface for sort in server.
1193 Added new members to statserv_options_block. It allows a server
1194 to read options from another source than just the command line. Thanks
1195 to Charles Woodfield.
1197 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1198 renamed to zboolean. Some C++ compilers complained about the name.
1200 Minor changes to gils.abs. Added index 's' (sort) on title
1201 and date/time-last-modified.
1203 --- 1.4pl2 1998/1/30
1205 Fixed bug in server library regarding inetd mode (-i). This bug
1206 was introduced by release 1.4.
1208 --- 1.4pl1 1998/1/29
1210 Added sort facility in client and backend server interface.
1212 Fixed problem with dependencies in Makefile(s).
1214 Fixed bugs for encoders/decoders of extended services and
1217 Implemented sub-tree feature for schemas. Sub-trees are
1218 referenced in *.abs-files. See explain.abs for an example
1219 of the use of this feature.
1221 Modified bib1.att; local attributes for ANY didn't include
1222 ANY itself (only affects use of the retrieval module).
1224 Fixed bug in plain SGML reader in function data1_read_node:
1225 tags with prefix "var" was incorrectly interpreted as variants.
1227 Added feature "sub-schemas" to enable references to - and definitions
1228 of - group of elements.
1230 * Removed member parent from type data1_element (in data1.h).
1232 Implemented function odr_nullval() that returns the value of
1235 * Removed member num_children from data1_node (in data1.h).
1237 Made NT service interface part of the server library. The
1238 function statserv_main uses the NT service when required and
1239 calls the statserv_start / statserv_close routines.
1241 Routine zget_SearchRequest and zget_PresentRequest fills
1242 resultSetName/Id member with "default" instead of "Default".
1244 Fixed memory leak in server. Request queue member wasn't freed.
1246 Fixed nmem_exit so that memory is freed.
1250 Revised the CCL parser utility to be thread safe.
1252 Added function, oid_ent_to_oid, to replace the function
1253 oid_getoidbyent, which is not thread safe.
1255 * Added nmem_init and nmem_exit to initialize and release
1256 NMEM resources. Function nmem_init should be called once in the
1257 initial thread before NMEM/ODR is used. statserv.c and client.c
1258 have been changed accordingly. The change was necessary to make
1259 NMEM thread safe. The NMEM memory pool is shared amongst threads
1260 in a process. Unix-based applications will still work fine without
1263 Added NT Services interface for the the Z39.50 (statserv) Server.
1264 Refer to the ztest.c source on the usage.
1266 Windows 95/NT port using MSVC5.0. Project files are included in the
1269 * Defined new 'global' handle for the retrieval (data1) system. The
1270 new handled, data1_handle, describes the state of the data1 system.
1271 This handle is passed as first argument to virtually all
1272 data1 related routines. The functions data1_create and data1_destroy
1273 creates and destroys a data1 handle respectively.
1275 Added ODR encode stream member to all backend request structures
1276 init, search, scan etc. This stream should be used to allocate all
1277 memory used for the response when thread safe operation is needed.
1279 Changed the comstack utility, cs_addstr, to be thread safe. The
1280 returned hostname string returned by the function is now part the
1283 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1284 function. The cs_straddr takes a COMSTACK handle as argument, so this
1285 function must be used after cs_create and before bind/connect.
1286 This function is thread safe.
1288 Moved test server to 'ztest' directory - generic server code still
1289 in 'server' directory.
1291 Made prefix query (pquery.c) utility thread safe.
1293 Added new function modifier YAZ_EXPORT to 'export' public DLL
1294 functions when using windows (see include/yconfig.h).
1296 Added definitions to the OID database (util/oid.c) (RVDM).
1298 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1300 Added call to ccl_rpn_delete in client program.
1302 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1303 release of RPN structure.
1305 Added support for C++, headers uses extern "C" for public definitions.
1306 With input from RVDM.
1308 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1309 Thanks to Ronald van der Meer (RVDM).
1311 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1313 Added support for private extensions to the OID database
1314 (oid_setprivateoids()). Thanks to RVDM.
1316 Added optional, physical ANY (key replication)
1318 Fixed null-reference problem in GRS-1 output filter.
1320 Proximity operator added to Prefix Query Format (PQF).
1322 In test client command "base" accepts multiple databases.
1324 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1328 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1330 Smallish bug-fixes in the new encoders/decoders (explain).
1332 Bug fixed in DeleteRequest.
1334 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1336 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1338 Added SOIF syntax (using private OID for now) to retrieval module and client.
1340 Added Update extended service.
1342 Added SearchResult-1 additional info structure.
1344 Added optional CCL (ISO8777) interpreter as separate module. Available
1347 --- 1.2 1996/6/10 (1st anniversary release)
1349 Added Summary record syntax. Lightly tested.
1351 Added OPAC record syntax. Untested.
1353 Added ResourceReport service encoders/decoders. Untested.
1355 Fixed bug in z_Unit - wrong tagging on unitSystem.
1357 Fixed bug in the DiagRecs decoder.
1359 Added options for max PDU size and session timeout to frontend-server.
1361 Added documentation of query-language parsers and other supporting utilities.
1363 [frontend-server] Added Attribute set to the bend_scanrequest API.
1365 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1366 surrogate diagnostics were generated.
1368 [retrieval] Allow multiple local values for attribute.
1370 [retrieval] Allow multiple attributes per element in .abs files. index type.
1372 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1374 --- 1.1pl2 1996/4/10
1376 Minor changes, mostly specific to Zebra's requirements (retrieval)
1380 Repaired bug in frontend server when running multiple listening
1381 endpoints in dynamic mode.
1383 z_External() now won't break if a known, ASN.1 value comes encapsulated
1384 in an octet-string. The value will pass through unmodified in an Odr_oct.
1386 Added a bit of code to the demo client to decode & display
1387 ASN.1-structured records represented in the octet-aligned branch of
1388 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1390 Added z_ext_getentbyref() to the ASN module. Doc updated.
1392 * Completed the SCAN definition in the ASN module. This may break SCAN
1393 code based on older YAZ-versions at compile-time. The fix is easy -
1396 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1397 under the SCAN definition. Remember to initialize this, server-people.
1399 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1400 that this does not extend to ODR and ASN.
1402 Comstack allows insertion of established socket (primarily for
1403 inetd-operation of servers). Doc updated.
1405 Front-end server can now start from the inetd in TCP mode. Doc
1408 --- 1.0pl4 1996/1/24
1412 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1413 the rank and record number.
1415 Adjustments to the frontend server.
1417 Fixed diagnostic BER dumper. It ignored the file argument.
1421 Various changes to retrieval module.
1423 Changed the union discriminators of the protocol files from enums to
1424 ints paired with #defines.
1426 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1429 *Changed operator in the RPN structure to 'roperator', again to avoid a
1432 Fixed problems in Explain decoders/encoders.
1434 --- 1.0pl2 1995/12/6
1436 Memory bug in log module fixed.
1438 --- 1.0pl1 1995/12/5
1440 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1442 Bug in Explain DatabaseInfo module fixed.
1444 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1448 The shift to v1.0 signals that we now consider the *core* functionality
1449 of YAZ reasonably stable (the core being more or less equivalent to
1450 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1451 tested (Explain not at all - though that will happen soonish).
1453 Minor changes to code to support Windows port.
1455 Various minor changes after we're getting to use GRS-1 & co. more.
1457 Added Espec-1 format.
1459 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1460 of the protocol and it cannot be selected when encoding (maps into 'string'
1461 when decoding). Needed to talk to some servers.
1463 Demo client can request simple element set names.
1465 Added Diagnostic Format encoders/decoders.
1467 Added simple Close handling to frontend server (no hooks for resource
1468 reporting yet), and demonstration client.
1470 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1472 --- 1.0b3 1995/08/24
1474 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1475 handled incorrectly when records were requested in the searchResponse. This
1476 will only affect you if you use the frontend-server.
1478 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1479 Test-client will ask for and print GRS1. Ztest will return dummy records
1482 Added Explain encoders/decoders to the service-level API. Untested.
1484 Added Extended Services: Item Order encoders and decoders to the Service-
1485 level API. Untested. We could use a recent copy of the pertinent bits
1486 of the ILL protocol to add those bits.
1488 Added diagnostic format 1 encoders/decoders to the service-level API.
1491 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1492 odr_cons.c, which causes a more correct output.
1494 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1495 was always set to 0 when no records were requested in the searchRequest.
1497 * Added better external-handling. This shouldn't harm old code that
1498 *encodes* externals. It can break code that looks for a
1499 'single-ASN1-type' representation, since those types that are known
1500 are now decoded immediately. Look at the SUTRS sample code in
1501 seshigh.c and client.c. Documentation updated.
1503 Handling of structured records in bend_fetchresponse. Length -1 marks
1504 structured record, type is deduced from format field.
1506 --- 1.0b2 1995/06/27
1507 Fairly quick maintenance release to add SUTRS support.
1509 Fixed handling of SUTRS records in the demonstration client.
1511 * Added format field to the bend_fetchrequest and bend_fetchresponce
1512 structures of the backend API (frontend server). When the record is
1513 returned, the value of the format field is mapped to an OID. The
1514 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1515 of the record. The special value VAL_NONE in the bend_request means
1516 that no specific format was requested by the client. Documentation
1517 updated accordingly. Test server (ztest) will return a fixed dummy
1518 SUTRS record if your client requests SUTRS.
1520 Documentation updated accordingly.
1522 You can now set external libraries and RANLIB support in the top-level
1526 First public release.
