1 Possible compatibility problems with earlier versions marked with '*'.
5 Added support for virtual hosts and multiple backend servers for
6 the YAZ frontend server. The configution is XML based and
7 support specificition of CQL to RPN mappings and explain information.
8 See section "Virtual Hosts" in the YAZ manual.
10 Extended OPAC display utility. OPAC display utility renders
11 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
12 to supplement yaz_marc_decode_wrbuf.
14 Fixed a bug in MARC decoder that could caused it to crash for some
15 invalid MARC records. More diagnostics and warnings where added in
16 XML output (warnings, etc are stored in comments).
20 Fixes for UNIX domain sockets. Bug #261.
22 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
24 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
25 Added yaz_marc_subfield_str which defines subfield lead string which is
26 used in YAZ_MARC_LINE format. Default string is blank+$. Added
27 yaz_marc_endline_str which defines end of fields string used in
28 YAZ_MARC_LINE format. Default string is newline.
30 Experimental support for MarcXChange. This format can be produced
31 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
32 http://www.bs.dk/standards/MarcXchange.xsd
34 Added yaz-client commands scansize that sets maximum number of
35 entries to be returned by scan.
39 Added support for SRW scan in yaz-client and Generic Frontend Server.
41 * Added whereInList member to SRW Scan Term.
43 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
45 Fixed NMEM system to return aligned blocks on the smallest boundaries
46 that are suitably aligned for all possible types on the particular
47 architecture YAZ is being built for.
51 Fixed numerious warnings that was issued with newer versions of GCC.
53 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
54 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
57 Make YAZ Generic Frontend Server slightly faster.
59 Enhance (and reduce) logging for Generic Frontend Server.
61 Revert YAZ log system so that it flushes every write operation
62 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
64 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
65 instead of LOG_, due to name clash with syslog(3). LOG_ are still
66 present. New applications should define YAZ_USE_NEW_LOG=1 - this
67 will effectively disable old definitions.
71 Added yaz_log_time_format which specifies log format using
74 Added yaz_log_module_level which returns mask for a module. Value
75 is non-zero mask a if module is enabled; zero if disabled.
77 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
80 Fixed bug #176: Dont throw diagnostics on empty SRU args.
82 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
84 Fixed bug #172: RPM builds does not enable SSL.
86 Doxyfile.in part of dist. Doxyfile generated by configure.
88 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
89 are given and the corresponding component does not exist.
91 Extend CCL documentation in YAZ reference. Describe r=r.
95 Fixed MARC->MARCXML conversion to properly deal with
96 fields, subfields, indicators having non-ASCII characters.
98 Fixed MARC->MARCXML conversion so that ASCII control characters
99 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
102 Added YAZ GFS support for conversion from Z39.50 surrogate
103 diagnostics to SRW surrogate diagnostics.
105 Bug fix: YAZ GFS did not return schema in explainResponse.
107 --- 2.0.25 2004/09/30
109 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
110 now converts recordSchema to elementSetName as well as schema URI.
112 Fixed bug in COMSTACK that prevented HTTP request packages from being
115 --- 2.0.24 2004/09/29
117 Added CCL facility r=r "range" which is similar to r=o "ordered" but
118 does not require white-space before and after the dash in a range, e.g.
119 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
122 Fixed a few AC_TRY_LINK configure tests that did not operate properly
123 due to new GCC removing "redundant" code.
125 Added yaz-client commands scanpos and scanstep that sets preferred
126 position and step-size for scan.
128 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
130 Added CCL utility ccl_qual_buf which parses one or more CCL
131 spec lines in a buffer.
133 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
134 of name and value - ignoring empty lines and comments.
136 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
138 Added odr_get_element_path which returns current element path for an
139 ODR handle. This utility is useful in error handling or user-defined
142 Added ODR_PRINT utility odr_set_stream which is is a more generic
143 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
144 to a write function and pointer to close function. The close function - if
145 non-NULL - will be called during odr_destroy.
147 Fixed bug in CCL parser where truncation char was not removed from
148 right side when truncation=both was in effect.
150 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
153 --- 2.0.23 2004/08/11
155 Fix buffer overrun in CQL parser when dealing with proximity (%).
157 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
158 to UTF-8/UCS conversion is now only based on codetables.xml.
160 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
162 --- 2.0.22 2004/08/06
164 Add support for more "commit changes" in ZOOM (uses Extended Services).
166 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
169 Yet another small fix for configure of SSL.
171 --- 2.0.21 2004/05/14
173 Fix SSL libs for configure when --with-openssl=DIR is given.
175 --- 2.0.20 2004/05/10
177 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
179 SSL comstack now uses yaz.pem certificate file on server side
180 by default. Certificate filename can be configured by calling
181 comstack function cs_set_ssl_certificate_file before cs_bind is used.
183 Fix bug regarding multiple calls to ZOOM_connection_connect.
185 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
187 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
188 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
190 ZOOM now allows inspection of X509 peer certificate for verification.
191 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
193 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
194 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
195 as "modular" but it simplifies things.
197 Added cs_get_peer_certificate to that returns peer X509 PEM.
199 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
200 NULL if SSL is unavailable.
202 Documentation about MARC decoding tools.
204 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
206 --- 2.0.19 2004/03/30
208 Rename CHANGELOG to NEWS to follow GNU style packing.
210 Fix bug with missing initialization of member in init_diagnostics.
211 This bug affects threaded version of GFS server.
213 --- 2.0.18 2004/03/20
215 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
218 Ensure zlib.dll is packed with Windows install.
220 --- 2.0.17 2004/03/17
222 Fix encoding of xsd:string to use text instead of CDATA.
224 Fix endless loop in CQL parser with unbalanced ".
226 Use a more compact way to store MARC-8 conversion tables.
228 --- 2.0.16 2004/03/16 Debian only
230 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
233 Update CQL parser to use new CQL 1.1 modifiers for booleans and
238 --- 2.0.15 2004/03/01
240 Another fix for decoding of XML packed records.
242 --- 2.0.14 2004/02/25
244 Fixes for Chunked encoding. White space not ignored after length spec.
246 Update NS and use default NS for SRW diagnostic elements.
248 --- 2.0.13 2004/02/23
250 Implement ZOOM_resultset_cache_reset which resets record cache.
252 Implement ZOOM_resultset_sort which sorts a result set.
254 Implement chunked HTTP transfer.
256 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
258 --- 2.0.12 2004/02/16
260 Added member 'schema' to bend_explain_rr structure so that backend
261 can specify explain record identifier. Defaults to Zeerex 2.0.
263 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
265 --- 2.0.11 2004/02/16
267 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
270 Added init command for yaz-client which sends "extra" init request.
272 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
273 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
275 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
277 Make ZOOM error code for "invalid query".
279 Fixed compilation for SSL which wasn't properly enabled for all platforms.
281 --- 2.0.10 2004/02/05
283 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
286 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
288 Added option -p <file> to make Generic Frontend Server to write PID file.
290 Added option -D to put Generic Frontend Server in background on its own.
292 Make ZOOM C recognize option "password". If unset, "pass" is used
293 (for backwards compatibility).
295 Fixed a bug in Generic Frontend Server that could make it crash if a
296 client sets characterSetNegotation bit, but didn't pass negotiation stuff
299 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
300 Must be issued before open, in order to be in effect.
302 --- 2.0.9-6 2004/01/12 Debian/Windows
304 Make the SRU server more picky WRT unknown params, etc.
306 Bug fix: ZOOM scan response didn't return displayTerm - when present.
308 New YAZ client command, options, that sets Z39.50 options.
310 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
311 options from a string of tokens (one token for each option bit).
313 Update SRW diagnostic code messages.
315 --- 2.0.9-5 2004/01/07 Debian/Windows
317 Handle user defined stylesheet for SRW/SRU.
319 --- 2.0.9-4 2004/01/06 Debian/Windows
321 Fix bug in decoding of Content-Length.
323 --- 2.0.9-3 2004/01/06 Debian/Windows
325 Fix a bug with decoding of XML packed records.
327 --- 2.0.9-2 2004/01/05 Debian only
329 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
331 Fix bug in SRW/SRU diagnostics decoding.
335 Fixed bug in Generic Frontend Server which could drop records exceeding
336 preferred message size. Reported and fixed by Irina Dijour.
338 Fixed calculation of package size for structured records in Generic
339 Frontend Server. Reported and fixed by Irina Dijour.
341 Fixed namespace for SRW/SRU diagnostics.
343 Fixed SEGV in yaz-client that occured for HTTP connection errors.
347 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
348 this version is incompatible with version 1.0 and older YAZ SRW/SRU
351 CQL changes to reflect recent changes to the specification:
352 * Documentation talks about context sets instead of index sets.
353 * Documentation talks about indexes instead of qualifiers.
354 * The CQL-to-PQF transformer's configuration file now uses
355 "index.set.name = <attributes>" instead of the old form
356 "qualifier.set.name = <attributes>". (Both forms are still
357 understood but the latter is deprecated.)
358 * CQL terms with no explicit index specified are now interpreted as
359 cql.serverChoice instead of srw.serverChoice (which of course
360 behaves exactly the same.)
364 MARC conversion can now generate ISO2709 output in another
365 character set. yaz-marcdump uses this facility if you invoke it
368 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
369 functions from there can be used from C++.
373 Frontend server now transfers memory from decoded packages to stream
376 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
377 references to show up.
379 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
380 the ZOOM Abstract API. The older names for the same options are still
381 also supported for the benefit of old applications.
383 ZOOM-C supports "implementationId" and "implementationVersion" options
384 to go along with "implementationName". These allow the user code to
385 specify identification strings to be sent to servers.
386 Add OID for the new ExtLite attribute set.
388 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
389 as requested/supplid by Ere Maijala <ere@atp.fi>
391 For generic frontend server, reverse the order of
392 "toolkit-supplied / application-supplied" strings sent as implementationId,
393 Name and Version. Also, remove the spaces around the slash. This brings
394 the GFS in line with the behaviour of ZOOM-C on the client side.
396 Add function ZOOM_scanset_display_term.
398 yaz-client shows scan displayTerm if present.
400 Utility yaz-iconv is now installed by default along with the man page
403 Extend configure check for OpenSSL to use pkg-config where available (such
406 Incorporate patch by Morten Bogeskov which allows a Unix file socket
407 server to specify uid/gid/mask for socket using the format
408 unix:[user=uid,][group=gid,][umask=mask,]file=path
409 If file= is omitted the existing format is assumed, e.g.
411 in which case the mask is 0666 (rw for everybody).
413 Major restructure of YAZ source. All source in libyaz is in src directory.
414 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
415 util (utility programs such as ASN.1 compiler, yaz-marcdump).
417 Added man page for utility yaz-marcdump (used to be called marcdump).
418 yaz-marcdump is installed by 'make install'.
420 Fixed a memory leak in Generic Frontend Server that occurred when decoding
421 of incoming package failed.
423 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
425 Change prototype of odr_perror: add const to message string.
427 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
429 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
430 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
431 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
432 DNS lookup. There should not be any compatibility problems with this
433 assuming that blocking=1 or 0 is used.
435 Fix bad reference in UNIX comstack in function cs_addrstr.
437 Fix for compilation on AIX.
439 The generic front-end server (server/seshigh.c) now supports returning
440 Init diagnostics to the client in User-information-field, in
441 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
446 Allow any CQL relation (not just all,any,exact,scr).
448 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
449 that features the same UI.
451 Implemented command update0 in YAZ client which is equivalent to
452 update but uses old of Ext Update ASN.1.
454 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
455 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
456 Previously no OID was used for this info.
458 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
459 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
460 returns 'malformed search term' otherwise.
462 SortResponse member resultCount now set to NULL in sort handler of
465 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
468 Add three new utility functions for translating OIDs between various
469 formats -- symbolic name such as "Usmarc", minus-1-terminated int
470 arrays and dotted strings such as "1.2.840.10003.9.5.1":
471 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
472 char *oid_to_dotstring(const int *oid, char *oidbuf);
473 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
475 Reverted modifications for ES Update definition for z_IU0Update
476 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
477 is back to YAZ 2.0.2.
479 String value attributes for CCL parser.
481 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
482 which their FirstSearch server returns in Init responses, sometimes
483 carrying useful diagnostic information when Init fails. This has the
484 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
485 "z39.50/oclcui.asn", where its definition is somewhat different from
486 what OCLC document on their web-site, as required to interoperate with
489 Support for anonymous authentication in yaz-client. Use the command
492 * Fix the OID of the Index Data-local "admin" Extended Service from
493 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
494 the 1000, which indicates a locally-defined OID, was a mistake.
498 Fix CCL directive @case handling so that it affects string match for
499 both CCL keywords and qualifiers.
501 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
502 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
503 Decoder has been updated with ASN.1 changes as listed in
504 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
505 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
506 z_IUUpdate, remains unchanged.
508 ZOOM_record_get may now return a record in a specific character set.
509 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
510 "from" is the character set of record as returned by target. "to" is
511 the character set to be returned. If omitted, "to" is UTF-8.
513 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
515 New ODR utility, odr_getelement, which returns name of element for
516 which encoding/decoding failed.
518 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
519 in cases where a required element was omitted.
521 Bug fix: some MARC8 sequences were not converted.
523 New ZOOM option "step" which specifies number of records to be
524 retrieved in one chunk. Used in conjunction with "start" and "count".
526 SRW support for yaz-client. Use scheme http: to use it, e.g.
529 yaz-client no longer does (un)intelligent character set conversions
530 by default. Can be enabled with charset and marc_charset commands.
532 xmalloc trace fix for 64-bit systems such as DEC alpha.
534 Solaris 2.6 compile fix.
536 New function, cql_strerror() translates SRW error codes, as returned
537 by cql_transform_error(), into human-readable English strings. Used
538 in yaz-client diagnostics when appropriate.
540 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
541 converts it into a type-1 query which is sent to the server. This
542 makes CQL available for use with all Z-servers, as opposed to the tiny
543 minority that can handle CQL queries themselves.
547 New Debian package layout similar to the Redhat Package layout.
549 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
550 and search result respectively.
554 Redhat package is now several packages: libyaz (runtime libraries),
555 libyaz-devel (development and documentation, and yaz (utility programs).
556 Package spec file by Morten Bøgeskov.
558 New member 'schema' in struct bend_fetch_rr which the name of requested
559 schema (SRW/SRU) for record (or NULL if none was given). The fetch
560 handler MAY set this to reflect the schema of the returned record.
562 New member 'display_term' in struct scan_entry. GFS now sets member entries
563 and allocates scan entries to be filled by user scan handler. In previous
564 version, entries member was allocated by the scan handler. That still works,
565 but the GFS will ignore member display_term - assuming it was NOT set by
566 the handler. The fact that the GFS now allocates the entries both allows
567 for new members and makes a scan handler easier to write.
569 Fix CQL lex buffer overflow.
571 SRW/SRU recordPacking. For SRW default recordPacking is string. For
572 SRU default recordPacking is string.
574 SRU protocol support for frontend server.
576 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
578 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
580 Added scan for the ZOOM shell (zoomsh).
584 * String Identifers for Schemas (Amendment 5).
585 http://lcweb.loc.gov/z3950/agency/amend/am5.html
586 Old definition for schema
587 Odr_oid *schema; /* OPT */
592 Z_InternationalString *uri;
593 #define Z_Schema_oid 1
594 #define Z_Schema_uri 2
597 * resultCount parameter to Sort Response (Amendment 1).
598 http://lcweb.loc.gov/z3950/agency/amend/am1.html
600 Support for SRW 1.0 over HTTP. This is an optional feature and
601 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
604 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
605 on the same port. SRW SearchRetrieveRequests are mapped
606 to bend_init,bend_search,bend_fetch,bend_close.
608 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
610 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
611 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
613 ZOOM connections are SRW based if schem http is used for hostname
614 in connect, e.g. z = ZOOM_connection_new("http://myserver");
615 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
617 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
618 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
619 distance=n, order=true/false, relation=le, prox unit=word. If
620 n is omitted, distance 1 is used.
622 Fixed problem with C compiler include path in wrong order.
624 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
625 on Solaris. Patch from Ko van der Sloot.
627 New MARC decode API. All new functions operate on a yaz_marc_t
628 handle. The most important new functions are: yaz_marc_create,
629 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
630 decode and destroy respectively. Decoder can produce formats
631 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
632 include/yaz/marcdisp.h.
634 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
635 to UTF-8, UCS-32, wchar_t or Latin-1.
637 * Prototypes for yaz_iconv_-functions moved to separate header
638 include/yaz/yaz-iconv.h.
640 Make a few private functions 'static' in unix.c. This prevents
641 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
643 For ZOOM connection, the options targetImplementation{Id,Name,Version}
644 are set when Init Response is received.
646 New function ZOOM_connection_error_x similar to ZOOM_connection_error
647 but returns diagnostic set as well.
649 New function yaz_strerror which is a portable wrapper for
650 strerror/strerror_r/GetLastMessage.
652 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
653 is returned for MARC. If type is "oai", then OAI MARC is returned.
655 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
660 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
662 Fix bad race conditions on SIGTERM and terminate gracefully in
665 Move retrieval (data1) module to Zebra since nobody seems to be
668 Add GRS-1 render for ZOOM using same format as yaz-client.
672 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
674 Fix broken ESpec handling in data1 module.
676 SGML reader parses comments and makes them part of the data1 tree.
678 Added several type casts so that YAZ compiles as C++ code.
680 ZOOM didn't handle PDU encoding failures properly.
682 Added more Bib-1 diagnostics (approved extensions).
684 GNU configure: better check for iconv.
686 More portable use of accept, getpeername. Check for socklen_t. Use
687 int/size_t if socklen_t is not defined.
691 PQF parser rejects bad queries - including those with extra
692 characters in them. PQF parser used to silently ignore that.
693 Cleaner API for PQF added, which allows you to get detailed
694 error information for bad queries (see yaz/pquery.h).
696 Fixed bug in ZOOM_record_get for type "database".
698 Implemented mini iconv library supporting conversions between
699 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
701 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
705 Fixed ZOOM C record cache so that preferredRecordSyntax and
706 elementSetName is used to check for already fetched records.
710 Added three members in bend_initrequest structure to facilitate
711 character set negotiation.
713 Fixed a bug in frontend server that could cause indefinite
714 loops under rare conditions.
716 Revised character set utilities (charneg.h) so that encoding
717 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
719 For PQF, directive @term <type> sets term type for Scan/Search.
720 Here <type> is general, string, numeric, null. The term type
721 is inherited - just like @attr.
723 New call odr_set_charset that sets character set conversion for
724 international-strings on a ODR stream. Prototype is:
725 int odr_set_charset(ODR o, const char *to, const char *from);
726 The InternationalString is still represented as C string in YAZ
727 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
728 won't). On the protocol level, you can use any encoding.
730 Support for UNIX sockets in ZOOM.
732 Solaris recv sometimes returns errno == ENOENT. It is treated as
733 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
735 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
736 both client and server. Code by Morten Bøgeskov.
740 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
741 that they can be used directly from Visual Basic. You must recompile
742 your windows APP if you're using ZOOM.
744 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
745 Commands "lang" and "charset" sets language and character set respectively.
746 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
747 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
749 Attributes from multiple CCL fields may be OR'ed rather than merged
750 using directive "@field or". Fields are still merged by default -
751 equivalent to "@field merge".
753 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
756 Fixed bug in zget for parameter ExtendedServicesResponse.
762 Added PQF feature: '@attr type=value' may be written as '@type=value'.
764 Client displays USR.1:SearchResult-1 (hits per term).
766 Additional Search Info for search in Generic Frontend Server.
768 Fixed CCL parsing of "field=s".
770 WIN32 installer - using the excellent NSIS software from nullsoft.
772 Fixed CCL parsing of "field = - <number>".
774 Added function yaz_marc_decode that decodes MARC for line mode
775 display or XML (similar to that used by JZKit).
777 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
778 Z39.50. But ISO/ILL was, however.
780 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
781 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
783 http://lcweb.loc.gov/z3950/agency/amend/am2.html
784 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
788 New YAZ client features: Command completion and new commands:
789 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
790 Code provided by Jacob Poulsen.
792 New call oid_trav, that visits all registered OIDs via callback.
794 Function ZOOM_record_get now returns const char pointer rather than
795 void pointer. It saves a lot of type casts.
797 For YAZ client, command "auth" now allows you to set authentication
798 in IdPass style. It is enabled when three tokens are given - order
799 is user, group and password.
801 Fix memory leaks in MARC record handling for ZOOM.
803 New option for YAZ client, -k <kilobytes> that sets
804 maximum record size. Similar to -k option for generic frontend
805 server and yaz-ztest.
807 More fixes for scan. Non-zero stepSize handled. OID's fixes.
809 Prefix query parser reports "fail" when bad attribute set is given.
811 Fix in MARC decoder. Proximity logging. Fix for attribute set
812 in scan handler for server. Patches by Shigeru Ishida.
814 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
817 Configure option --with-openssl=<dir> now works when a directory is
818 specified. Patch provided by Morten Bøgeskov.
820 New option for YAZ client, -u <auth>, that sets authentication.
822 ZOOM fix: error information was sometimes "missing", since error
823 was cleared/reset too when it shouldn't.
825 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
829 Scan for ZOOM API. New object ZOOM_scanset. New functions
830 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
831 ZOOM_scanset_destroy.
833 New ZOOM function, ZOOM_connection_last_event, that returns type
834 of last event (such as "receive data", "send data", "apdu received",
837 New ZOOM option, schema, that specifies schema for retrieval.
839 New CCL feature. Qualifiers can be aliases for one or more
840 other qualifiers (if more than one is given, OR is used).
842 ZOOM uses named result sets if target supports it.
844 Two new YAZ client commands: . (dot, which sources a script of YAZ
845 client commands), and ! (to execute shell command.). Implemented
848 Working on Debian packages.
852 YAZ client enables named result sets only if target supports it.
854 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
856 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
857 with key="host" to get same result.
859 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
860 Function Z3950_resultset_record(s) returns references to records
861 "owned" by resultset. To become owner use Z3950_record_clone.
863 Function z_ext_record handles Extended Services. Thanks to
868 CCL Parser fix: ignore token comma when dealing with and-lists.
870 Documentation updates for COMSTACK.
872 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
873 Changed prototype Z3950_records. For some functions, int parameters
874 were changed to size_t.
876 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
879 New MARC decode/display function, marc_display_exl, which properly rejects
880 non-ISO2709 records. YAZ client uses it.
884 Fix bug: local attribute set wasn't set correctly in PQF strings.
888 * Old Z39.50 codecs no longer supported.
890 Added ZOOM C binding. See http://zoom.z3950.org/
892 Renamed states for COMSTACKs to avoid confusion with events.
894 Implemented cs_look and proper cs_rcvconnect.
896 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
898 Configure detects POSIX threads on OpenBSD.
900 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
901 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
903 When error is returned from present handler, non-surrogate diagnostic
904 is returned in present response (and fetch handler is no longer called).
906 * Minor adjustments to pquery parser (PQF). Token characters may be
907 escaped by using backslash (C-style).
909 PQF parser allows string attribute values to be specified. For @attr,
910 non-numeric characters after the equal-sign are treated as strings
911 (e.g. @attr 9=title).
913 CCL trunction character may be defined (@truncation in file)
915 * function zget_ExtendedServicesRequest sets waitAction to
916 waitIfPossible (was wait).
918 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
921 CCL operator names may be set in field definition files (CCL_bibset).
922 See ccl/bib1 for an example.
924 Fixes in ASN.1 compiler for C++ compatibility.
926 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
927 and "op_or" to avoid conflict with C++.
929 Fixed problem with GNU readline detection on Redhat 7.0.
931 Added step-size for Scan backend handler.
933 Fixed bug that made the frontend server crash when no attribute
934 set was specified for scan.
936 Front-end server automatically switches to original working directory
937 when installed as an NT service. Previously -w had to be specified to
940 Added extended attributes for retrieval module (data1), so that data1
941 records carry d1_readXML/SGML attributes. d1_read also supports
942 null-data rules ( <tag/>)
944 On UNIX when POSIX threads are available, a separate library libyazthread
945 is created. Programmers should link with that library and the yaz library
946 when using threads. The reason for the split was that some applications
947 on Linux, such as Apache, doesn't work well when using shared objects that
950 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
951 (or any frontend server) in SSL mode by specifying ssl: followed by
952 address. Only tested on UNIX.
954 Added feature for CCL module. Virtual structure s=al or s=ol generates
955 and-list and or-list respectively instead of phrase search.
959 * Added prefix "yaz_" for the functions log_init.., log_file.. and
960 log_mask_str. This was done to avoid name conflicts with other libraries
961 (such as other PHP extensions).
963 Added raw OID member for preferred record syntax (request_format_raw)
964 and returned record syntax (output_format_raw) for backend fetch method.
966 Config file yaz-config now accepts options so that it returns specific
967 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
969 Shared library support for UNIX using GNU libtool.
971 * Modified backend interface. Request/Response struct's replaced by
972 one read/write C struct. For example bend_fetchrequest and
973 bend_fetchresult have been replaced by single bend_fetch_rr struct.
974 Every handler - even search has to be registered in bend_init
975 handler. This means that the YAZ library no longer refers to
976 external functions and it makes it possible to make the whole
977 thing a single DLL/SO.
979 Added Segment handler for backend server.
981 Added Zmbol/Zebra administrative functions to YAZ client.
983 Threaded frontend server on UNIX (when POSIX Threads are available).
984 Starting the server with option -T enables multi-threading.
988 Added configure option --enable-comp/disable-comp to control use
989 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
990 located in sub directory asn.
992 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
993 in ${exec_prefix}/bin along with the other programs yaz-client and
996 GNU automake used to maintain makefiles.
1000 Changed retrieval module so that we can load records with no abstract
1001 syntax defined. Tagpaths in these records are fully composed of string
1004 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1008 On UNIX, the generated makefile now supports a proper 'make install'.
1009 The prefix can be set via GNU configure to set the install location
1010 (default is /usr/local).
1012 * YAZ programs client and ztest were renamed to yaz-client and
1013 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1014 locations, such as /usr/bin,/usr/local/bin,etc.
1016 * YAZ Header files were moved from include to include/yaz. YAZ Header
1017 files are referred to as include <yaz/log.h> rather than <log.h>.
1018 The YAZ include path (-I ..) is therefore the same as before. Programmers
1019 should update their #include statements or use -Ipath/include/yaz
1020 instead. The main motivation for doing this change is that YAZ header files
1021 can be installed in "standard" locations /usr/include,/usr/local/include
1022 without introducing conflicts, since ALL YAZ header files are stored
1023 in subdirectory yaz (under /usr/include for example).
1025 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1026 rather than project/workspace files. We switched because project files
1027 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1030 Changed name of logging function, logf, to yaz_log, to prevent name
1031 clash with some math-log functions. The YAZ header log.h defines logf
1032 to yaz_log (#define) so there should be no incompatibilities by this
1035 Added bend_start/bend_stop handlers for server. These handler are
1036 called on start/stop of server. For windows they are called whenever
1037 a service is started/stopped.
1039 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1040 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1041 in util/yc.tcl. The auto-generated C code structures are, in a few
1042 cases, incompatible with the old decoders. There are differences in the
1043 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1044 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1045 The preprocessor variable ASN_COMPILED is defined when the compiled
1046 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1047 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1048 wish to use the old encoders/decoders you can specify --disable-yc
1051 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1052 version so that it supports both new - and old version of DB Update
1054 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1055 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1056 change. The name parameter can be set to 0 in which no name is specified
1057 for the construction. The macros odr_implicit and odr_explicit sets name
1058 parameter to zero for the construction involved. New macros
1059 odr_implicit_tag and odr_explicit_tag are similar to the others,
1060 except that a name parameter is added. For programmers' that don't use
1061 ODR they probably only need to change the call to z_APDU and z_External.
1063 Added access control facility by interfacing the TCP wrapper library.
1064 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1065 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1066 name of the daemon and enables the access control as specified in
1067 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1069 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1070 den Dool <H.M.vdnDool@kub.nl>.
1072 Added reference ID parameter to most functions in server API - refer
1073 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1075 Changed name of ccl library to libccl.a (was ccl.a).
1077 Fixed bug in decoder for Explain (Category TargetInfo).
1079 Added support for GNU readline in client. Thanks to Jacob Poulsen
1080 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1082 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1083 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1084 IMPLEMENTATION! This change was made to the development version before
1085 the ZIG decided to retract the amendment. If any users MUST be
1086 compatible with the original Update definition, PLEASE CONTACT US, and
1087 we will include a separate definition corresponding to the old Update
1088 ES. Note that because of the change to the ASN.1 of the
1089 TaskPackageRecordStructure we cannot define a single structure that
1090 will support both versions.
1092 * Added const modifier to buffer parameter for some ODR/BER encoding
1093 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1094 completeWAIS, odr_dumpBER.
1096 Fixed bug in client.c which caused a crash when a scanResponse didn't
1097 contain positionOfTerm.
1099 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1100 * will cause an error in a client if a non-YAZ target sends both a
1101 * list of Scan entries and non-surrogate diagnostics.
1103 Retrieval module enhancements. Tag sets may be typed in the reference
1104 to it. From the .abs-file the "tagset" directive takes a third optional
1105 integer type for the tag set referenced. From a .tag-file the "include"
1106 directive takes a third optional type as well. The old "type" directive
1107 in the tag set itself is still recognized but acts as the default type
1110 Backend interface change. Individual Scan terms returned from bend_scan
1111 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1112 in include/backend.h.
1114 Retrieval module enhancements. Multiple tag sets and attribute sets may
1115 be specified in abstract syntax specs. Revised the error/warning for
1116 logging messages reported by the retrieval module when reading the
1119 Object Identifier system (oid_..) changed. The API is backwards
1120 compatible but the oid-routines now allocates new OID's when needed.
1121 Raw OID's may be specified in oid_getvalbyname.
1123 YAZ now uses GNU configure to generate Makefile(s).
1125 * Minor changes in some of the member names of DeleteResultSetRequest and
1126 DeleteResultSetResponse. See include/proto.h.
1128 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1129 and added member 'languages' in TargetInfo (which was missing).
1131 Changed the way attribute sets are handled in the retrieval
1132 module. These are now cached, just like the abstract syntaxes
1135 Changed YAZ so that it links with compiled ASN.1.
1137 Added Explain-schema definitions and mapping routines. The following
1138 Explain categories have been implemented: AttributeDetails,
1139 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1141 Fixed minor bug in Windows version of Server Library.
1143 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1145 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1147 Added EXTERNAL: UNIverse Resource Report (non-standard).
1149 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1150 ENUMERATED and SET OF.
1152 * Added 'const' to some of the char pointer arguments for the
1153 functions, data1_read_node, data1_getelementbytagname,
1154 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1157 Fixed bug in data1_insert_taggeddata - the last_child member of
1158 parent wasn't initialised.
1160 * Changed data1_read_record and data1_read_node so that the supplied
1161 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1162 doesn't refer to any parts of the "SGML"-buffer.
1164 Fixed bug in server library (Windows version of statserv_remove).
1166 * Changed code so that it compiles as C++. The type definition
1167 of Odr_fun which is a member of Odr_arm was changed. The result is,
1168 that an explicit typecast is needed for the fun pointer when
1169 using Odr_arm - as in:
1170 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1172 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1174 Implemented the new structured date and time definition as approved
1175 by the ZIG. Added schemaId element to the specificTag in Espec-1
1176 (also approved at the last ZIG). Thanks to RVDM.
1178 Added some Object identifiers (RVDM).
1180 Changed the Update Extended Service (RVDM).
1182 Added command "refid" to client which specifies referenceId for
1183 the following requests.
1185 Implemented extended service handling for server. See ztest.c
1186 for an example as well as backend.h. New handlers are registerd
1187 in the Init handler.
1189 * Changed interface for sort in server.
1191 Added new members to statserv_options_block. It allows a server
1192 to read options from another source than just the command line. Thanks
1193 to Charles Woodfield.
1195 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1196 renamed to zboolean. Some C++ compilers complained about the name.
1198 Minor changes to gils.abs. Added index 's' (sort) on title
1199 and date/time-last-modified.
1201 --- 1.4pl2 1998/1/30
1203 Fixed bug in server library regarding inetd mode (-i). This bug
1204 was introduced by release 1.4.
1206 --- 1.4pl1 1998/1/29
1208 Added sort facility in client and backend server interface.
1210 Fixed problem with dependencies in Makefile(s).
1212 Fixed bugs for encoders/decoders of extended services and
1215 Implemented sub-tree feature for schemas. Sub-trees are
1216 referenced in *.abs-files. See explain.abs for an example
1217 of the use of this feature.
1219 Modified bib1.att; local attributes for ANY didn't include
1220 ANY itself (only affects use of the retrieval module).
1222 Fixed bug in plain SGML reader in function data1_read_node:
1223 tags with prefix "var" was incorrectly interpreted as variants.
1225 Added feature "sub-schemas" to enable references to - and definitions
1226 of - group of elements.
1228 * Removed member parent from type data1_element (in data1.h).
1230 Implemented function odr_nullval() that returns the value of
1233 * Removed member num_children from data1_node (in data1.h).
1235 Made NT service interface part of the server library. The
1236 function statserv_main uses the NT service when required and
1237 calls the statserv_start / statserv_close routines.
1239 Routine zget_SearchRequest and zget_PresentRequest fills
1240 resultSetName/Id member with "default" instead of "Default".
1242 Fixed memory leak in server. Request queue member wasn't freed.
1244 Fixed nmem_exit so that memory is freed.
1248 Revised the CCL parser utility to be thread safe.
1250 Added function, oid_ent_to_oid, to replace the function
1251 oid_getoidbyent, which is not thread safe.
1253 * Added nmem_init and nmem_exit to initialize and release
1254 NMEM resources. Function nmem_init should be called once in the
1255 initial thread before NMEM/ODR is used. statserv.c and client.c
1256 have been changed accordingly. The change was necessary to make
1257 NMEM thread safe. The NMEM memory pool is shared amongst threads
1258 in a process. Unix-based applications will still work fine without
1261 Added NT Services interface for the the Z39.50 (statserv) Server.
1262 Refer to the ztest.c source on the usage.
1264 Windows 95/NT port using MSVC5.0. Project files are included in the
1267 * Defined new 'global' handle for the retrieval (data1) system. The
1268 new handled, data1_handle, describes the state of the data1 system.
1269 This handle is passed as first argument to virtually all
1270 data1 related routines. The functions data1_create and data1_destroy
1271 creates and destroys a data1 handle respectively.
1273 Added ODR encode stream member to all backend request structures
1274 init, search, scan etc. This stream should be used to allocate all
1275 memory used for the response when thread safe operation is needed.
1277 Changed the comstack utility, cs_addstr, to be thread safe. The
1278 returned hostname string returned by the function is now part the
1281 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1282 function. The cs_straddr takes a COMSTACK handle as argument, so this
1283 function must be used after cs_create and before bind/connect.
1284 This function is thread safe.
1286 Moved test server to 'ztest' directory - generic server code still
1287 in 'server' directory.
1289 Made prefix query (pquery.c) utility thread safe.
1291 Added new function modifier YAZ_EXPORT to 'export' public DLL
1292 functions when using windows (see include/yconfig.h).
1294 Added definitions to the OID database (util/oid.c) (RVDM).
1296 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1298 Added call to ccl_rpn_delete in client program.
1300 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1301 release of RPN structure.
1303 Added support for C++, headers uses extern "C" for public definitions.
1304 With input from RVDM.
1306 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1307 Thanks to Ronald van der Meer (RVDM).
1309 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1311 Added support for private extensions to the OID database
1312 (oid_setprivateoids()). Thanks to RVDM.
1314 Added optional, physical ANY (key replication)
1316 Fixed null-reference problem in GRS-1 output filter.
1318 Proximity operator added to Prefix Query Format (PQF).
1320 In test client command "base" accepts multiple databases.
1322 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1326 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1328 Smallish bug-fixes in the new encoders/decoders (explain).
1330 Bug fixed in DeleteRequest.
1332 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1334 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1336 Added SOIF syntax (using private OID for now) to retrieval module and client.
1338 Added Update extended service.
1340 Added SearchResult-1 additional info structure.
1342 Added optional CCL (ISO8777) interpreter as separate module. Available
1345 --- 1.2 1996/6/10 (1st anniversary release)
1347 Added Summary record syntax. Lightly tested.
1349 Added OPAC record syntax. Untested.
1351 Added ResourceReport service encoders/decoders. Untested.
1353 Fixed bug in z_Unit - wrong tagging on unitSystem.
1355 Fixed bug in the DiagRecs decoder.
1357 Added options for max PDU size and session timeout to frontend-server.
1359 Added documentation of query-language parsers and other supporting utilities.
1361 [frontend-server] Added Attribute set to the bend_scanrequest API.
1363 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1364 surrogate diagnostics were generated.
1366 [retrieval] Allow multiple local values for attribute.
1368 [retrieval] Allow multiple attributes per element in .abs files. index type.
1370 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1372 --- 1.1pl2 1996/4/10
1374 Minor changes, mostly specific to Zebra's requirements (retrieval)
1378 Repaired bug in frontend server when running multiple listening
1379 endpoints in dynamic mode.
1381 z_External() now won't break if a known, ASN.1 value comes encapsulated
1382 in an octet-string. The value will pass through unmodified in an Odr_oct.
1384 Added a bit of code to the demo client to decode & display
1385 ASN.1-structured records represented in the octet-aligned branch of
1386 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1388 Added z_ext_getentbyref() to the ASN module. Doc updated.
1390 * Completed the SCAN definition in the ASN module. This may break SCAN
1391 code based on older YAZ-versions at compile-time. The fix is easy -
1394 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1395 under the SCAN definition. Remember to initialize this, server-people.
1397 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1398 that this does not extend to ODR and ASN.
1400 Comstack allows insertion of established socket (primarily for
1401 inetd-operation of servers). Doc updated.
1403 Front-end server can now start from the inetd in TCP mode. Doc
1406 --- 1.0pl4 1996/1/24
1410 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1411 the rank and record number.
1413 Adjustments to the frontend server.
1415 Fixed diagnostic BER dumper. It ignored the file argument.
1419 Various changes to retrieval module.
1421 Changed the union discriminators of the protocol files from enums to
1422 ints paired with #defines.
1424 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1427 *Changed operator in the RPN structure to 'roperator', again to avoid a
1430 Fixed problems in Explain decoders/encoders.
1432 --- 1.0pl2 1995/12/6
1434 Memory bug in log module fixed.
1436 --- 1.0pl1 1995/12/5
1438 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1440 Bug in Explain DatabaseInfo module fixed.
1442 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1446 The shift to v1.0 signals that we now consider the *core* functionality
1447 of YAZ reasonably stable (the core being more or less equivalent to
1448 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1449 tested (Explain not at all - though that will happen soonish).
1451 Minor changes to code to support Windows port.
1453 Various minor changes after we're getting to use GRS-1 & co. more.
1455 Added Espec-1 format.
1457 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1458 of the protocol and it cannot be selected when encoding (maps into 'string'
1459 when decoding). Needed to talk to some servers.
1461 Demo client can request simple element set names.
1463 Added Diagnostic Format encoders/decoders.
1465 Added simple Close handling to frontend server (no hooks for resource
1466 reporting yet), and demonstration client.
1468 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1470 --- 1.0b3 1995/08/24
1472 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1473 handled incorrectly when records were requested in the searchResponse. This
1474 will only affect you if you use the frontend-server.
1476 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1477 Test-client will ask for and print GRS1. Ztest will return dummy records
1480 Added Explain encoders/decoders to the service-level API. Untested.
1482 Added Extended Services: Item Order encoders and decoders to the Service-
1483 level API. Untested. We could use a recent copy of the pertinent bits
1484 of the ILL protocol to add those bits.
1486 Added diagnostic format 1 encoders/decoders to the service-level API.
1489 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1490 odr_cons.c, which causes a more correct output.
1492 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1493 was always set to 0 when no records were requested in the searchRequest.
1495 * Added better external-handling. This shouldn't harm old code that
1496 *encodes* externals. It can break code that looks for a
1497 'single-ASN1-type' representation, since those types that are known
1498 are now decoded immediately. Look at the SUTRS sample code in
1499 seshigh.c and client.c. Documentation updated.
1501 Handling of structured records in bend_fetchresponse. Length -1 marks
1502 structured record, type is deduced from format field.
1504 --- 1.0b2 1995/06/27
1505 Fairly quick maintenance release to add SUTRS support.
1507 Fixed handling of SUTRS records in the demonstration client.
1509 * Added format field to the bend_fetchrequest and bend_fetchresponce
1510 structures of the backend API (frontend server). When the record is
1511 returned, the value of the format field is mapped to an OID. The
1512 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1513 of the record. The special value VAL_NONE in the bend_request means
1514 that no specific format was requested by the client. Documentation
1515 updated accordingly. Test server (ztest) will return a fixed dummy
1516 SUTRS record if your client requests SUTRS.
1518 Documentation updated accordingly.
1520 You can now set external libraries and RANLIB support in the top-level
1524 First public release.
