1 Possible compatibility problems with earlier versions marked with '*'.
3 Added support for SRW scan in yaz-client.
5 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
7 Fixed NMEM system to return aligned blocks on the smallest boundaries
8 that are suitably aligned for all possible types on the particular
9 architecture YAZ is being built for.
13 Fixed numerious warnings that was issued with newer versions of GCC.
15 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
16 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
19 Make YAZ Generic Frontend Server slightly faster.
21 Enhance (and reduce) logging for Generic Frontend Server.
23 Revert YAZ log system so that it flushes every write operation
24 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
26 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
27 instead of LOG_, due to name clash with syslog(3). LOG_ are still
28 present. New applications should define YAZ_USE_NEW_LOG=1 - this
29 will effectively disable old definitions.
33 Added yaz_log_time_format which specifies log format using
36 Added yaz_log_module_level which returns mask for a module. Value
37 is non-zero mask a if module is enabled; zero if disabled.
39 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
42 Fixed bug #176: Dont throw diagnostics on empty SRU args.
44 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
46 Fixed bug #172: RPM builds does not enable SSL.
48 Doxyfile.in part of dist. Doxyfile generated by configure.
50 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
51 are given and the corresponding component does not exist.
53 Extend CCL documentation in YAZ reference. Describe r=r.
57 Fixed MARC->MARCXML conversion to properly deal with
58 fields, subfields, indicators having non-ASCII characters.
60 Fixed MARC->MARCXML conversion so that ASCII control characters
61 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
64 Added YAZ GFS support for conversion from Z39.50 surrogate
65 diagnostics to SRW surrogate diagnostics.
67 Bug fix: YAZ GFS did not return schema in explainResponse.
71 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
72 now converts recordSchema to elementSetName as well as schema URI.
74 Fixed bug in COMSTACK that prevented HTTP request packages from being
79 Added CCL facility r=r "range" which is similar to r=o "ordered" but
80 does not require white-space before and after the dash in a range, e.g.
81 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
84 Fixed a few AC_TRY_LINK configure tests that did not operate properly
85 due to new GCC removing "redundant" code.
87 Added yaz-client commands scanpos and scanstep that sets preferred
88 position and step-size for scan.
90 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
92 Added CCL utility ccl_qual_buf which parses one or more CCL
93 spec lines in a buffer.
95 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
96 of name and value - ignoring empty lines and comments.
98 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
100 Added odr_get_element_path which returns current element path for an
101 ODR handle. This utility is useful in error handling or user-defined
104 Added ODR_PRINT utility odr_set_stream which is is a more generic
105 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
106 to a write function and pointer to close function. The close function - if
107 non-NULL - will be called during odr_destroy.
109 Fixed bug in CCL parser where truncation char was not removed from
110 right side when truncation=both was in effect.
112 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
115 --- 2.0.23 2004/08/11
117 Fix buffer overrun in CQL parser when dealing with proximity (%).
119 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
120 to UTF-8/UCS conversion is now only based on codetables.xml.
122 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
124 --- 2.0.22 2004/08/06
126 Add support for more "commit changes" in ZOOM (uses Extended Services).
128 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
131 Yet another small fix for configure of SSL.
133 --- 2.0.21 2004/05/14
135 Fix SSL libs for configure when --with-openssl=DIR is given.
137 --- 2.0.20 2004/05/10
139 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
141 SSL comstack now uses yaz.pem certificate file on server side
142 by default. Certificate filename can be configured by calling
143 comstack function cs_set_ssl_certificate_file before cs_bind is used.
145 Fix bug regarding multiple calls to ZOOM_connection_connect.
147 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
149 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
150 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
152 ZOOM now allows inspection of X509 peer certificate for verification.
153 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
155 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
156 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
157 as "modular" but it simplifies things.
159 Added cs_get_peer_certificate to that returns peer X509 PEM.
161 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
162 NULL if SSL is unavailable.
164 Documentation about MARC decoding tools.
166 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
168 --- 2.0.19 2004/03/30
170 Rename CHANGELOG to NEWS to follow GNU style packing.
172 Fix bug with missing initialization of member in init_diagnostics.
173 This bug affects threaded version of GFS server.
175 --- 2.0.18 2004/03/20
177 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
180 Ensure zlib.dll is packed with Windows install.
182 --- 2.0.17 2004/03/17
184 Fix encoding of xsd:string to use text instead of CDATA.
186 Fix endless loop in CQL parser with unbalanced ".
188 Use a more compact way to store MARC-8 conversion tables.
190 --- 2.0.16 2004/03/16 Debian only
192 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
195 Update CQL parser to use new CQL 1.1 modifiers for booleans and
200 --- 2.0.15 2004/03/01
202 Another fix for decoding of XML packed records.
204 --- 2.0.14 2004/02/25
206 Fixes for Chunked encoding. White space not ignored after length spec.
208 Update NS and use default NS for SRW diagnostic elements.
210 --- 2.0.13 2004/02/23
212 Implement ZOOM_resultset_cache_reset which resets record cache.
214 Implement ZOOM_resultset_sort which sorts a result set.
216 Implement chunked HTTP transfer.
218 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
220 --- 2.0.12 2004/02/16
222 Added member 'schema' to bend_explain_rr structure so that backend
223 can specify explain record identifier. Defaults to Zeerex 2.0.
225 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
227 --- 2.0.11 2004/02/16
229 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
232 Added init command for yaz-client which sends "extra" init request.
234 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
235 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
237 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
239 Make ZOOM error code for "invalid query".
241 Fixed compilation for SSL which wasn't properly enabled for all platforms.
243 --- 2.0.10 2004/02/05
245 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
248 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
250 Added option -p <file> to make Generic Frontend Server to write PID file.
252 Added option -D to put Generic Frontend Server in background on its own.
254 Make ZOOM C recognize option "password". If unset, "pass" is used
255 (for backwards compatibility).
257 Fixed a bug in Generic Frontend Server that could make it crash if a
258 client sets characterSetNegotation bit, but didn't pass negotiation stuff
261 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
262 Must be issued before open, in order to be in effect.
264 --- 2.0.9-6 2004/01/12 Debian/Windows
266 Make the SRU server more picky WRT unknown params, etc.
268 Bug fix: ZOOM scan response didn't return displayTerm - when present.
270 New YAZ client command, options, that sets Z39.50 options.
272 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
273 options from a string of tokens (one token for each option bit).
275 Update SRW diagnostic code messages.
277 --- 2.0.9-5 2004/01/07 Debian/Windows
279 Handle user defined stylesheet for SRW/SRU.
281 --- 2.0.9-4 2004/01/06 Debian/Windows
283 Fix bug in decoding of Content-Length.
285 --- 2.0.9-3 2004/01/06 Debian/Windows
287 Fix a bug with decoding of XML packed records.
289 --- 2.0.9-2 2004/01/05 Debian only
291 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
293 Fix bug in SRW/SRU diagnostics decoding.
297 Fixed bug in Generic Frontend Server which could drop records exceeding
298 preferred message size. Reported and fixed by Irina Dijour.
300 Fixed calculation of package size for structured records in Generic
301 Frontend Server. Reported and fixed by Irina Dijour.
303 Fixed namespace for SRW/SRU diagnostics.
305 Fixed SEGV in yaz-client that occured for HTTP connection errors.
309 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
310 this version is incompatible with version 1.0 and older YAZ SRW/SRU
313 CQL changes to reflect recent changes to the specification:
314 * Documentation talks about context sets instead of index sets.
315 * Documentation talks about indexes instead of qualifiers.
316 * The CQL-to-PQF transformer's configuration file now uses
317 "index.set.name = <attributes>" instead of the old form
318 "qualifier.set.name = <attributes>". (Both forms are still
319 understood but the latter is deprecated.)
320 * CQL terms with no explicit index specified are now interpreted as
321 cql.serverChoice instead of srw.serverChoice (which of course
322 behaves exactly the same.)
326 MARC conversion can now generate ISO2709 output in another
327 character set. yaz-marcdump uses this facility if you invoke it
330 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
331 functions from there can be used from C++.
335 Frontend server now transfers memory from decoded packages to stream
338 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
339 references to show up.
341 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
342 the ZOOM Abstract API. The older names for the same options are still
343 also supported for the benefit of old applications.
345 ZOOM-C supports "implementationId" and "implementationVersion" options
346 to go along with "implementationName". These allow the user code to
347 specify identification strings to be sent to servers.
348 Add OID for the new ExtLite attribute set.
350 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
351 as requested/supplid by Ere Maijala <ere@atp.fi>
353 For generic frontend server, reverse the order of
354 "toolkit-supplied / application-supplied" strings sent as implementationId,
355 Name and Version. Also, remove the spaces around the slash. This brings
356 the GFS in line with the behaviour of ZOOM-C on the client side.
358 Add function ZOOM_scanset_display_term.
360 yaz-client shows scan displayTerm if present.
362 Utility yaz-iconv is now installed by default along with the man page
365 Extend configure check for OpenSSL to use pkg-config where available (such
368 Incorporate patch by Morten Bogeskov which allows a Unix file socket
369 server to specify uid/gid/mask for socket using the format
370 unix:[user=uid,][group=gid,][umask=mask,]file=path
371 If file= is omitted the existing format is assumed, e.g.
373 in which case the mask is 0666 (rw for everybody).
375 Major restructure of YAZ source. All source in libyaz is in src directory.
376 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
377 util (utility programs such as ASN.1 compiler, yaz-marcdump).
379 Added man page for utility yaz-marcdump (used to be called marcdump).
380 yaz-marcdump is installed by 'make install'.
382 Fixed a memory leak in Generic Frontend Server that occurred when decoding
383 of incoming package failed.
385 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
387 Change prototype of odr_perror: add const to message string.
389 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
391 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
392 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
393 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
394 DNS lookup. There should not be any compatibility problems with this
395 assuming that blocking=1 or 0 is used.
397 Fix bad reference in UNIX comstack in function cs_addrstr.
399 Fix for compilation on AIX.
401 The generic front-end server (server/seshigh.c) now supports returning
402 Init diagnostics to the client in User-information-field, in
403 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
408 Allow any CQL relation (not just all,any,exact,scr).
410 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
411 that features the same UI.
413 Implemented command update0 in YAZ client which is equivalent to
414 update but uses old of Ext Update ASN.1.
416 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
417 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
418 Previously no OID was used for this info.
420 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
421 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
422 returns 'malformed search term' otherwise.
424 SortResponse member resultCount now set to NULL in sort handler of
427 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
430 Add three new utility functions for translating OIDs between various
431 formats -- symbolic name such as "Usmarc", minus-1-terminated int
432 arrays and dotted strings such as "1.2.840.10003.9.5.1":
433 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
434 char *oid_to_dotstring(const int *oid, char *oidbuf);
435 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
437 Reverted modifications for ES Update definition for z_IU0Update
438 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
439 is back to YAZ 2.0.2.
441 String value attributes for CCL parser.
443 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
444 which their FirstSearch server returns in Init responses, sometimes
445 carrying useful diagnostic information when Init fails. This has the
446 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
447 "z39.50/oclcui.asn", where its definition is somewhat different from
448 what OCLC document on their web-site, as required to interoperate with
451 Support for anonymous authentication in yaz-client. Use the command
454 * Fix the OID of the Index Data-local "admin" Extended Service from
455 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
456 the 1000, which indicates a locally-defined OID, was a mistake.
460 Fix CCL directive @case handling so that it affects string match for
461 both CCL keywords and qualifiers.
463 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
464 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
465 Decoder has been updated with ASN.1 changes as listed in
466 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
467 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
468 z_IUUpdate, remains unchanged.
470 ZOOM_record_get may now return a record in a specific character set.
471 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
472 "from" is the character set of record as returned by target. "to" is
473 the character set to be returned. If omitted, "to" is UTF-8.
475 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
477 New ODR utility, odr_getelement, which returns name of element for
478 which encoding/decoding failed.
480 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
481 in cases where a required element was omitted.
483 Bug fix: some MARC8 sequences were not converted.
485 New ZOOM option "step" which specifies number of records to be
486 retrieved in one chunk. Used in conjunction with "start" and "count".
488 SRW support for yaz-client. Use scheme http: to use it, e.g.
491 yaz-client no longer does (un)intelligent character set conversions
492 by default. Can be enabled with charset and marc_charset commands.
494 xmalloc trace fix for 64-bit systems such as DEC alpha.
496 Solaris 2.6 compile fix.
498 New function, cql_strerror() translates SRW error codes, as returned
499 by cql_transform_error(), into human-readable English strings. Used
500 in yaz-client diagnostics when appropriate.
502 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
503 converts it into a type-1 query which is sent to the server. This
504 makes CQL available for use with all Z-servers, as opposed to the tiny
505 minority that can handle CQL queries themselves.
509 New Debian package layout similar to the Redhat Package layout.
511 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
512 and search result respectively.
516 Redhat package is now several packages: libyaz (runtime libraries),
517 libyaz-devel (development and documentation, and yaz (utility programs).
518 Package spec file by Morten Bøgeskov.
520 New member 'schema' in struct bend_fetch_rr which the name of requested
521 schema (SRW/SRU) for record (or NULL if none was given). The fetch
522 handler MAY set this to reflect the schema of the returned record.
524 New member 'display_term' in struct scan_entry. GFS now sets member entries
525 and allocates scan entries to be filled by user scan handler. In previous
526 version, entries member was allocated by the scan handler. That still works,
527 but the GFS will ignore member display_term - assuming it was NOT set by
528 the handler. The fact that the GFS now allocates the entries both allows
529 for new members and makes a scan handler easier to write.
531 Fix CQL lex buffer overflow.
533 SRW/SRU recordPacking. For SRW default recordPacking is string. For
534 SRU default recordPacking is string.
536 SRU protocol support for frontend server.
538 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
540 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
542 Added scan for the ZOOM shell (zoomsh).
546 * String Identifers for Schemas (Amendment 5).
547 http://lcweb.loc.gov/z3950/agency/amend/am5.html
548 Old definition for schema
549 Odr_oid *schema; /* OPT */
554 Z_InternationalString *uri;
555 #define Z_Schema_oid 1
556 #define Z_Schema_uri 2
559 * resultCount parameter to Sort Response (Amendment 1).
560 http://lcweb.loc.gov/z3950/agency/amend/am1.html
562 Support for SRW 1.0 over HTTP. This is an optional feature and
563 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
566 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
567 on the same port. SRW SearchRetrieveRequests are mapped
568 to bend_init,bend_search,bend_fetch,bend_close.
570 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
572 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
573 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
575 ZOOM connections are SRW based if schem http is used for hostname
576 in connect, e.g. z = ZOOM_connection_new("http://myserver");
577 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
579 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
580 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
581 distance=n, order=true/false, relation=le, prox unit=word. If
582 n is omitted, distance 1 is used.
584 Fixed problem with C compiler include path in wrong order.
586 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
587 on Solaris. Patch from Ko van der Sloot.
589 New MARC decode API. All new functions operate on a yaz_marc_t
590 handle. The most important new functions are: yaz_marc_create,
591 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
592 decode and destroy respectively. Decoder can produce formats
593 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
594 include/yaz/marcdisp.h.
596 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
597 to UTF-8, UCS-32, wchar_t or Latin-1.
599 * Prototypes for yaz_iconv_-functions moved to separate header
600 include/yaz/yaz-iconv.h.
602 Make a few private functions 'static' in unix.c. This prevents
603 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
605 For ZOOM connection, the options targetImplementation{Id,Name,Version}
606 are set when Init Response is received.
608 New function ZOOM_connection_error_x similar to ZOOM_connection_error
609 but returns diagnostic set as well.
611 New function yaz_strerror which is a portable wrapper for
612 strerror/strerror_r/GetLastMessage.
614 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
615 is returned for MARC. If type is "oai", then OAI MARC is returned.
617 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
622 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
624 Fix bad race conditions on SIGTERM and terminate gracefully in
627 Move retrieval (data1) module to Zebra since nobody seems to be
630 Add GRS-1 render for ZOOM using same format as yaz-client.
634 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
636 Fix broken ESpec handling in data1 module.
638 SGML reader parses comments and makes them part of the data1 tree.
640 Added several type casts so that YAZ compiles as C++ code.
642 ZOOM didn't handle PDU encoding failures properly.
644 Added more Bib-1 diagnostics (approved extensions).
646 GNU configure: better check for iconv.
648 More portable use of accept, getpeername. Check for socklen_t. Use
649 int/size_t if socklen_t is not defined.
653 PQF parser rejects bad queries - including those with extra
654 characters in them. PQF parser used to silently ignore that.
655 Cleaner API for PQF added, which allows you to get detailed
656 error information for bad queries (see yaz/pquery.h).
658 Fixed bug in ZOOM_record_get for type "database".
660 Implemented mini iconv library supporting conversions between
661 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
663 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
667 Fixed ZOOM C record cache so that preferredRecordSyntax and
668 elementSetName is used to check for already fetched records.
672 Added three members in bend_initrequest structure to facilitate
673 character set negotiation.
675 Fixed a bug in frontend server that could cause indefinite
676 loops under rare conditions.
678 Revised character set utilities (charneg.h) so that encoding
679 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
681 For PQF, directive @term <type> sets term type for Scan/Search.
682 Here <type> is general, string, numeric, null. The term type
683 is inherited - just like @attr.
685 New call odr_set_charset that sets character set conversion for
686 international-strings on a ODR stream. Prototype is:
687 int odr_set_charset(ODR o, const char *to, const char *from);
688 The InternationalString is still represented as C string in YAZ
689 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
690 won't). On the protocol level, you can use any encoding.
692 Support for UNIX sockets in ZOOM.
694 Solaris recv sometimes returns errno == ENOENT. It is treated as
695 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
697 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
698 both client and server. Code by Morten Bøgeskov.
702 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
703 that they can be used directly from Visual Basic. You must recompile
704 your windows APP if you're using ZOOM.
706 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
707 Commands "lang" and "charset" sets language and character set respectively.
708 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
709 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
711 Attributes from multiple CCL fields may be OR'ed rather than merged
712 using directive "@field or". Fields are still merged by default -
713 equivalent to "@field merge".
715 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
718 Fixed bug in zget for parameter ExtendedServicesResponse.
724 Added PQF feature: '@attr type=value' may be written as '@type=value'.
726 Client displays USR.1:SearchResult-1 (hits per term).
728 Additional Search Info for search in Generic Frontend Server.
730 Fixed CCL parsing of "field=s".
732 WIN32 installer - using the excellent NSIS software from nullsoft.
734 Fixed CCL parsing of "field = - <number>".
736 Added function yaz_marc_decode that decodes MARC for line mode
737 display or XML (similar to that used by JZKit).
739 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
740 Z39.50. But ISO/ILL was, however.
742 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
743 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

746 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
750 New YAZ client features: Command completion and new commands:
751 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
752 Code provided by Jacob Poulsen.
754 New call oid_trav, that visits all registered OIDs via callback.
756 Function ZOOM_record_get now returns const char pointer rather than
757 void pointer. It saves a lot of type casts.
759 For YAZ client, command "auth" now allows you to set authentication
760 in IdPass style. It is enabled when three tokens are given - order
761 is user, group and password.
763 Fix memory leaks in MARC record handling for ZOOM.
765 New option for YAZ client, -k <kilobytes> that sets
766 maximum record size. Similar to -k option for generic frontend
767 server and yaz-ztest.
769 More fixes for scan. Non-zero stepSize handled. OID's fixes.
771 Prefix query parser reports "fail" when bad attribute set is given.
773 Fix in MARC decoder. Proximity logging. Fix for attribute set
774 in scan handler for server. Patches by Shigeru Ishida.
776 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
779 Configure option --with-openssl=<dir> now works when a directory is
780 specified. Patch provided by Morten Bøgeskov.
782 New option for YAZ client, -u <auth>, that sets authentication.
784 ZOOM fix: error information was sometimes "missing", since error
785 was cleared/reset too when it shouldn't.
787 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
791 Scan for ZOOM API. New object ZOOM_scanset. New functions
792 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
793 ZOOM_scanset_destroy.
795 New ZOOM function, ZOOM_connection_last_event, that returns type
796 of last event (such as "receive data", "send data", "apdu received",
799 New ZOOM option, schema, that specifies schema for retrieval.
801 New CCL feature. Qualifiers can be aliases for one or more
802 other qualifiers (if more than one is given, OR is used).
804 ZOOM uses named result sets if target supports it.
806 Two new YAZ client commands: . (dot, which sources a script of YAZ
807 client commands), and ! (to execute shell command.). Implemented
810 Working on Debian packages.
814 YAZ client enables named result sets only if target supports it.
816 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
818 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
819 with key="host" to get same result.
821 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
822 Function Z3950_resultset_record(s) returns references to records
823 "owned" by resultset. To become owner use Z3950_record_clone.
825 Function z_ext_record handles Extended Services. Thanks to
830 CCL Parser fix: ignore token comma when dealing with and-lists.
832 Documentation updates for COMSTACK.
834 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
835 Changed prototype Z3950_records. For some functions, int parameters
836 were changed to size_t.
838 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
841 New MARC decode/display function, marc_display_exl, which properly rejects
842 non-ISO2709 records. YAZ client uses it.
846 Fix bug: local attribute set wasn't set correctly in PQF strings.
850 * Old Z39.50 codecs no longer supported.
852 Added ZOOM C binding. See http://zoom.z3950.org/
854 Renamed states for COMSTACKs to avoid confusion with events.
856 Implemented cs_look and proper cs_rcvconnect.
858 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
860 Configure detects POSIX threads on OpenBSD.
862 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
863 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
865 When error is returned from present handler, non-surrogate diagnostic
866 is returned in present response (and fetch handler is no longer called).
868 * Minor adjustments to pquery parser (PQF). Token characters may be
869 escaped by using backslash (C-style).
871 PQF parser allows string attribute values to be specified. For @attr,
872 non-numeric characters after the equal-sign are treated as strings
873 (e.g. @attr 9=title).
875 CCL trunction character may be defined (@truncation in file)
877 * function zget_ExtendedServicesRequest sets waitAction to
878 waitIfPossible (was wait).
880 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
883 CCL operator names may be set in field definition files (CCL_bibset).
884 See ccl/bib1 for an example.
886 Fixes in ASN.1 compiler for C++ compatibility.
888 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
889 and "op_or" to avoid conflict with C++.
891 Fixed problem with GNU readline detection on Redhat 7.0.
893 Added step-size for Scan backend handler.
895 Fixed bug that made the frontend server crash when no attribute
896 set was specified for scan.
898 Front-end server automatically switches to original working directory
899 when installed as an NT service. Previously -w had to be specified to
902 Added extended attributes for retrieval module (data1), so that data1
903 records carry d1_readXML/SGML attributes. d1_read also supports
904 null-data rules ( <tag/>)
906 On UNIX when POSIX threads are available, a separate library libyazthread
907 is created. Programmers should link with that library and the yaz library
908 when using threads. The reason for the split was that some applications
909 on Linux, such as Apache, doesn't work well when using shared objects that
912 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
913 (or any frontend server) in SSL mode by specifying ssl: followed by
914 address. Only tested on UNIX.
916 Added feature for CCL module. Virtual structure s=al or s=ol generates
917 and-list and or-list respectively instead of phrase search.
921 * Added prefix "yaz_" for the functions log_init.., log_file.. and
922 log_mask_str. This was done to avoid name conflicts with other libraries
923 (such as other PHP extensions).
925 Added raw OID member for preferred record syntax (request_format_raw)
926 and returned record syntax (output_format_raw) for backend fetch method.
928 Config file yaz-config now accepts options so that it returns specific
929 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
931 Shared library support for UNIX using GNU libtool.
933 * Modified backend interface. Request/Response struct's replaced by
934 one read/write C struct. For example bend_fetchrequest and
935 bend_fetchresult have been replaced by single bend_fetch_rr struct.
936 Every handler - even search has to be registered in bend_init
937 handler. This means that the YAZ library no longer refers to
938 external functions and it makes it possible to make the whole
939 thing a single DLL/SO.
941 Added Segment handler for backend server.
943 Added Zmbol/Zebra administrative functions to YAZ client.
945 Threaded frontend server on UNIX (when POSIX Threads are available).
946 Starting the server with option -T enables multi-threading.
950 Added configure option --enable-comp/disable-comp to control use
951 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
952 located in sub directory asn.
954 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
955 in ${exec_prefix}/bin along with the other programs yaz-client and
958 GNU automake used to maintain makefiles.
962 Changed retrieval module so that we can load records with no abstract
963 syntax defined. Tagpaths in these records are fully composed of string
966 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
970 On UNIX, the generated makefile now supports a proper 'make install'.
971 The prefix can be set via GNU configure to set the install location
972 (default is /usr/local).
974 * YAZ programs client and ztest were renamed to yaz-client and
975 yaz-ztest to avoid conflicts when users install YAZ in "standard"
976 locations, such as /usr/bin,/usr/local/bin,etc.
978 * YAZ Header files were moved from include to include/yaz. YAZ Header
979 files are referred to as include <yaz/log.h> rather than <log.h>.
980 The YAZ include path (-I ..) is therefore the same as before. Programmers
981 should update their #include statements or use -Ipath/include/yaz
982 instead. The main motivation for doing this change is that YAZ header files
983 can be installed in "standard" locations /usr/include,/usr/local/include
984 without introducing conflicts, since ALL YAZ header files are stored
985 in subdirectory yaz (under /usr/include for example).
987 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
988 rather than project/workspace files. We switched because project files
989 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
992 Changed name of logging function, logf, to yaz_log, to prevent name
993 clash with some math-log functions. The YAZ header log.h defines logf
994 to yaz_log (#define) so there should be no incompatibilities by this
997 Added bend_start/bend_stop handlers for server. These handler are
998 called on start/stop of server. For windows they are called whenever
999 a service is started/stopped.
1001 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1002 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1003 in util/yc.tcl. The auto-generated C code structures are, in a few
1004 cases, incompatible with the old decoders. There are differences in the
1005 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1006 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1007 The preprocessor variable ASN_COMPILED is defined when the compiled
1008 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1009 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1010 wish to use the old encoders/decoders you can specify --disable-yc
1013 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1014 version so that it supports both new - and old version of DB Update
1016 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1017 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1018 change. The name parameter can be set to 0 in which no name is specified
1019 for the construction. The macros odr_implicit and odr_explicit sets name
1020 parameter to zero for the construction involved. New macros
1021 odr_implicit_tag and odr_explicit_tag are similar to the others,
1022 except that a name parameter is added. For programmers' that don't use
1023 ODR they probably only need to change the call to z_APDU and z_External.
1025 Added access control facility by interfacing the TCP wrapper library.
1026 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1027 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1028 name of the daemon and enables the access control as specified in
1029 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1031 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1032 den Dool <H.M.vdnDool@kub.nl>.
1034 Added reference ID parameter to most functions in server API - refer
1035 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1037 Changed name of ccl library to libccl.a (was ccl.a).
1039 Fixed bug in decoder for Explain (Category TargetInfo).
1041 Added support for GNU readline in client. Thanks to Jacob Poulsen
1042 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1044 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1045 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1046 IMPLEMENTATION! This change was made to the development version before
1047 the ZIG decided to retract the amendment. If any users MUST be
1048 compatible with the original Update definition, PLEASE CONTACT US, and
1049 we will include a separate definition corresponding to the old Update
1050 ES. Note that because of the change to the ASN.1 of the
1051 TaskPackageRecordStructure we cannot define a single structure that
1052 will support both versions.
1054 * Added const modifier to buffer parameter for some ODR/BER encoding
1055 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1056 completeWAIS, odr_dumpBER.
1058 Fixed bug in client.c which caused a crash when a scanResponse didn't
1059 contain positionOfTerm.
1061 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1062 * will cause an error in a client if a non-YAZ target sends both a
1063 * list of Scan entries and non-surrogate diagnostics.
1065 Retrieval module enhancements. Tag sets may be typed in the reference
1066 to it. From the .abs-file the "tagset" directive takes a third optional
1067 integer type for the tag set referenced. From a .tag-file the "include"
1068 directive takes a third optional type as well. The old "type" directive
1069 in the tag set itself is still recognized but acts as the default type
1072 Backend interface change. Individual Scan terms returned from bend_scan
1073 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1074 in include/backend.h.
1076 Retrieval module enhancements. Multiple tag sets and attribute sets may
1077 be specified in abstract syntax specs. Revised the error/warning for
1078 logging messages reported by the retrieval module when reading the
1081 Object Identifier system (oid_..) changed. The API is backwards
1082 compatible but the oid-routines now allocates new OID's when needed.
1083 Raw OID's may be specified in oid_getvalbyname.
1085 YAZ now uses GNU configure to generate Makefile(s).
1087 * Minor changes in some of the member names of DeleteResultSetRequest and
1088 DeleteResultSetResponse. See include/proto.h.
1090 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1091 and added member 'languages' in TargetInfo (which was missing).
1093 Changed the way attribute sets are handled in the retrieval
1094 module. These are now cached, just like the abstract syntaxes
1097 Changed YAZ so that it links with compiled ASN.1.
1099 Added Explain-schema definitions and mapping routines. The following
1100 Explain categories have been implemented: AttributeDetails,
1101 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1103 Fixed minor bug in Windows version of Server Library.
1105 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1107 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1109 Added EXTERNAL: UNIverse Resource Report (non-standard).
1111 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1112 ENUMERATED and SET OF.
1114 * Added 'const' to some of the char pointer arguments for the
1115 functions, data1_read_node, data1_getelementbytagname,
1116 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1119 Fixed bug in data1_insert_taggeddata - the last_child member of
1120 parent wasn't initialised.
1122 * Changed data1_read_record and data1_read_node so that the supplied
1123 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1124 doesn't refer to any parts of the "SGML"-buffer.
1126 Fixed bug in server library (Windows version of statserv_remove).
1128 * Changed code so that it compiles as C++. The type definition
1129 of Odr_fun which is a member of Odr_arm was changed. The result is,
1130 that an explicit typecast is needed for the fun pointer when
1131 using Odr_arm - as in:
1132 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1134 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1136 Implemented the new structured date and time definition as approved
1137 by the ZIG. Added schemaId element to the specificTag in Espec-1
1138 (also approved at the last ZIG). Thanks to RVDM.
1140 Added some Object identifiers (RVDM).
1142 Changed the Update Extended Service (RVDM).
1144 Added command "refid" to client which specifies referenceId for
1145 the following requests.
1147 Implemented extended service handling for server. See ztest.c
1148 for an example as well as backend.h. New handlers are registerd
1149 in the Init handler.
1151 * Changed interface for sort in server.
1153 Added new members to statserv_options_block. It allows a server
1154 to read options from another source than just the command line. Thanks
1155 to Charles Woodfield.
1157 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1158 renamed to zboolean. Some C++ compilers complained about the name.
1160 Minor changes to gils.abs. Added index 's' (sort) on title
1161 and date/time-last-modified.
1163 --- 1.4pl2 1998/1/30
1165 Fixed bug in server library regarding inetd mode (-i). This bug
1166 was introduced by release 1.4.
1168 --- 1.4pl1 1998/1/29
1170 Added sort facility in client and backend server interface.
1172 Fixed problem with dependencies in Makefile(s).
1174 Fixed bugs for encoders/decoders of extended services and
1177 Implemented sub-tree feature for schemas. Sub-trees are
1178 referenced in *.abs-files. See explain.abs for an example
1179 of the use of this feature.
1181 Modified bib1.att; local attributes for ANY didn't include
1182 ANY itself (only affects use of the retrieval module).
1184 Fixed bug in plain SGML reader in function data1_read_node:
1185 tags with prefix "var" was incorrectly interpreted as variants.
1187 Added feature "sub-schemas" to enable references to - and definitions
1188 of - group of elements.
1190 * Removed member parent from type data1_element (in data1.h).
1192 Implemented function odr_nullval() that returns the value of
1195 * Removed member num_children from data1_node (in data1.h).
1197 Made NT service interface part of the server library. The
1198 function statserv_main uses the NT service when required and
1199 calls the statserv_start / statserv_close routines.
1201 Routine zget_SearchRequest and zget_PresentRequest fills
1202 resultSetName/Id member with "default" instead of "Default".
1204 Fixed memory leak in server. Request queue member wasn't freed.
1206 Fixed nmem_exit so that memory is freed.
1210 Revised the CCL parser utility to be thread safe.
1212 Added function, oid_ent_to_oid, to replace the function
1213 oid_getoidbyent, which is not thread safe.
1215 * Added nmem_init and nmem_exit to initialize and release
1216 NMEM resources. Function nmem_init should be called once in the
1217 initial thread before NMEM/ODR is used. statserv.c and client.c
1218 have been changed accordingly. The change was necessary to make
1219 NMEM thread safe. The NMEM memory pool is shared amongst threads
1220 in a process. Unix-based applications will still work fine without
1223 Added NT Services interface for the the Z39.50 (statserv) Server.
1224 Refer to the ztest.c source on the usage.
1226 Windows 95/NT port using MSVC5.0. Project files are included in the
1229 * Defined new 'global' handle for the retrieval (data1) system. The
1230 new handled, data1_handle, describes the state of the data1 system.
1231 This handle is passed as first argument to virtually all
1232 data1 related routines. The functions data1_create and data1_destroy
1233 creates and destroys a data1 handle respectively.
1235 Added ODR encode stream member to all backend request structures
1236 init, search, scan etc. This stream should be used to allocate all
1237 memory used for the response when thread safe operation is needed.
1239 Changed the comstack utility, cs_addstr, to be thread safe. The
1240 returned hostname string returned by the function is now part the
1243 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1244 function. The cs_straddr takes a COMSTACK handle as argument, so this
1245 function must be used after cs_create and before bind/connect.
1246 This function is thread safe.
1248 Moved test server to 'ztest' directory - generic server code still
1249 in 'server' directory.
1251 Made prefix query (pquery.c) utility thread safe.
1253 Added new function modifier YAZ_EXPORT to 'export' public DLL
1254 functions when using windows (see include/yconfig.h).
1256 Added definitions to the OID database (util/oid.c) (RVDM).
1258 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1260 Added call to ccl_rpn_delete in client program.
1262 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1263 release of RPN structure.
1265 Added support for C++, headers uses extern "C" for public definitions.
1266 With input from RVDM.
1268 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1269 Thanks to Ronald van der Meer (RVDM).
1271 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1273 Added support for private extensions to the OID database
1274 (oid_setprivateoids()). Thanks to RVDM.
1276 Added optional, physical ANY (key replication)
1278 Fixed null-reference problem in GRS-1 output filter.
1280 Proximity operator added to Prefix Query Format (PQF).
1282 In test client command "base" accepts multiple databases.
1284 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1288 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1290 Smallish bug-fixes in the new encoders/decoders (explain).
1292 Bug fixed in DeleteRequest.
1294 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1296 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1298 Added SOIF syntax (using private OID for now) to retrieval module and client.
1300 Added Update extended service.
1302 Added SearchResult-1 additional info structure.
1304 Added optional CCL (ISO8777) interpreter as separate module. Available
1307 --- 1.2 1996/6/10 (1st anniversary release)
1309 Added Summary record syntax. Lightly tested.
1311 Added OPAC record syntax. Untested.
1313 Added ResourceReport service encoders/decoders. Untested.
1315 Fixed bug in z_Unit - wrong tagging on unitSystem.
1317 Fixed bug in the DiagRecs decoder.
1319 Added options for max PDU size and session timeout to frontend-server.
1321 Added documentation of query-language parsers and other supporting utilities.
1323 [frontend-server] Added Attribute set to the bend_scanrequest API.
1325 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1326 surrogate diagnostics were generated.
1328 [retrieval] Allow multiple local values for attribute.
1330 [retrieval] Allow multiple attributes per element in .abs files. index type.
1332 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1334 --- 1.1pl2 1996/4/10
1336 Minor changes, mostly specific to Zebra's requirements (retrieval)
1340 Repaired bug in frontend server when running multiple listening
1341 endpoints in dynamic mode.
1343 z_External() now won't break if a known, ASN.1 value comes encapsulated
1344 in an octet-string. The value will pass through unmodified in an Odr_oct.
1346 Added a bit of code to the demo client to decode & display
1347 ASN.1-structured records represented in the octet-aligned branch of
1348 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1350 Added z_ext_getentbyref() to the ASN module. Doc updated.
1352 * Completed the SCAN definition in the ASN module. This may break SCAN
1353 code based on older YAZ-versions at compile-time. The fix is easy -
1356 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1357 under the SCAN definition. Remember to initialize this, server-people.
1359 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1360 that this does not extend to ODR and ASN.
1362 Comstack allows insertion of established socket (primarily for
1363 inetd-operation of servers). Doc updated.
1365 Front-end server can now start from the inetd in TCP mode. Doc
1368 --- 1.0pl4 1996/1/24
1372 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1373 the rank and record number.
1375 Adjustments to the frontend server.
1377 Fixed diagnostic BER dumper. It ignored the file argument.
1381 Various changes to retrieval module.
1383 Changed the union discriminators of the protocol files from enums to
1384 ints paired with #defines.
1386 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1389 *Changed operator in the RPN structure to 'roperator', again to avoid a
1392 Fixed problems in Explain decoders/encoders.
1394 --- 1.0pl2 1995/12/6
1396 Memory bug in log module fixed.
1398 --- 1.0pl1 1995/12/5
1400 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1402 Bug in Explain DatabaseInfo module fixed.
1404 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1408 The shift to v1.0 signals that we now consider the *core* functionality
1409 of YAZ reasonably stable (the core being more or less equivalent to
1410 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1411 tested (Explain not at all - though that will happen soonish).
1413 Minor changes to code to support Windows port.
1415 Various minor changes after we're getting to use GRS-1 & co. more.
1417 Added Espec-1 format.
1419 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1420 of the protocol and it cannot be selected when encoding (maps into 'string'
1421 when decoding). Needed to talk to some servers.
1423 Demo client can request simple element set names.
1425 Added Diagnostic Format encoders/decoders.
1427 Added simple Close handling to frontend server (no hooks for resource
1428 reporting yet), and demonstration client.
1430 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1432 --- 1.0b3 1995/08/24
1434 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1435 handled incorrectly when records were requested in the searchResponse. This
1436 will only affect you if you use the frontend-server.
1438 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1439 Test-client will ask for and print GRS1. Ztest will return dummy records
1442 Added Explain encoders/decoders to the service-level API. Untested.
1444 Added Extended Services: Item Order encoders and decoders to the Service-
1445 level API. Untested. We could use a recent copy of the pertinent bits
1446 of the ILL protocol to add those bits.
1448 Added diagnostic format 1 encoders/decoders to the service-level API.
1451 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1452 odr_cons.c, which causes a more correct output.
1454 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1455 was always set to 0 when no records were requested in the searchRequest.
1457 * Added better external-handling. This shouldn't harm old code that
1458 *encodes* externals. It can break code that looks for a
1459 'single-ASN1-type' representation, since those types that are known
1460 are now decoded immediately. Look at the SUTRS sample code in
1461 seshigh.c and client.c. Documentation updated.
1463 Handling of structured records in bend_fetchresponse. Length -1 marks
1464 structured record, type is deduced from format field.
1466 --- 1.0b2 1995/06/27
1467 Fairly quick maintenance release to add SUTRS support.
1469 Fixed handling of SUTRS records in the demonstration client.
1471 * Added format field to the bend_fetchrequest and bend_fetchresponce
1472 structures of the backend API (frontend server). When the record is
1473 returned, the value of the format field is mapped to an OID. The
1474 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1475 of the record. The special value VAL_NONE in the bend_request means
1476 that no specific format was requested by the client. Documentation
1477 updated accordingly. Test server (ztest) will return a fixed dummy
1478 SUTRS record if your client requests SUTRS.
1480 Documentation updated accordingly.
1482 You can now set external libraries and RANLIB support in the top-level
1486 First public release.
