1 Possible compatibility problems with earlier versions marked with '*'.
5 Fixed numerious warnings that was issued with newer versions of GCC.
7 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
8 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
11 Make YAZ Generic Frontend Server slightly faster.
13 Enhance (and reduce) logging for Generic Frontend Server.
15 Revert YAZ log system so that it flushes every write operation
16 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
18 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
19 instead of LOG_, due to name clash with syslog(3). LOG_ are still
20 present. New applications should define YAZ_USE_NEW_LOG=1 - this
21 will effectively disable old definitions.
25 Added yaz_log_time_format which specifies log format using
28 Added yaz_log_module_level which returns mask for a module. Value
29 is non-zero mask a if module is enabled; zero if disabled.
31 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
34 Fixed bug #176: Dont throw diagnostics on empty SRU args.
36 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
38 Fixed bug #172: RPM builds does not enable SSL.
40 Doxyfile.in part of dist. Doxyfile generated by configure.
42 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
43 are given and the corresponding component does not exist.
45 Extend CCL documentation in YAZ reference. Describe r=r.
49 Fixed MARC->MARCXML conversion to properly deal with
50 fields, subfields, indicators having non-ASCII characters.
52 Fixed MARC->MARCXML conversion so that ASCII control characters
53 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
56 Added YAZ GFS support for conversion from Z39.50 surrogate
57 diagnostics to SRW surrogate diagnostics.
59 Bug fix: YAZ GFS did not return schema in explainResponse.
63 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
64 now converts recordSchema to elementSetName as well as schema URI.
66 Fixed bug in COMSTACK that prevented HTTP request packages from being
71 Added CCL facility r=r "range" which is similar to r=o "ordered" but
72 does not require white-space before and after the dash in a range, e.g.
73 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
76 Fixed a few AC_TRY_LINK configure tests that did not operate properly
77 due to new GCC removing "redundant" code.
79 Added yaz-client commands scanpos and scanstep that sets preferred
80 position and step-size for scan.
82 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
84 Added CCL utility ccl_qual_buf which parses one or more CCL
85 spec lines in a buffer.
87 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
88 of name and value - ignoring empty lines and comments.
90 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
92 Added odr_get_element_path which returns current element path for an
93 ODR handle. This utility is useful in error handling or user-defined
96 Added ODR_PRINT utility odr_set_stream which is is a more generic
97 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
98 to a write function and pointer to close function. The close function - if
99 non-NULL - will be called during odr_destroy.
101 Fixed bug in CCL parser where truncation char was not removed from
102 right side when truncation=both was in effect.
104 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
107 --- 2.0.23 2004/08/11
109 Fix buffer overrun in CQL parser when dealing with proximity (%).
111 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
112 to UTF-8/UCS conversion is now only based on codetables.xml.
114 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
116 --- 2.0.22 2004/08/06
118 Add support for more "commit changes" in ZOOM (uses Extended Services).
120 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
123 Yet another small fix for configure of SSL.
125 --- 2.0.21 2004/05/14
127 Fix SSL libs for configure when --with-openssl=DIR is given.
129 --- 2.0.20 2004/05/10
131 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
133 SSL comstack now uses yaz.pem certificate file on server side
134 by default. Certificate filename can be configured by calling
135 comstack function cs_set_ssl_certificate_file before cs_bind is used.
137 Fix bug regarding multiple calls to ZOOM_connection_connect.
139 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
141 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
142 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
144 ZOOM now allows inspection of X509 peer certificate for verification.
145 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
147 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
148 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
149 as "modular" but it simplifies things.
151 Added cs_get_peer_certificate to that returns peer X509 PEM.
153 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
154 NULL if SSL is unavailable.
156 Documentation about MARC decoding tools.
158 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
160 --- 2.0.19 2004/03/30
162 Rename CHANGELOG to NEWS to follow GNU style packing.
164 Fix bug with missing initialization of member in init_diagnostics.
165 This bug affects threaded version of GFS server.
167 --- 2.0.18 2004/03/20
169 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
172 Ensure zlib.dll is packed with Windows install.
174 --- 2.0.17 2004/03/17
176 Fix encoding of xsd:string to use text instead of CDATA.
178 Fix endless loop in CQL parser with unbalanced ".
180 Use a more compact way to store MARC-8 conversion tables.
182 --- 2.0.16 2004/03/16 Debian only
184 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
187 Update CQL parser to use new CQL 1.1 modifiers for booleans and
192 --- 2.0.15 2004/03/01
194 Another fix for decoding of XML packed records.
196 --- 2.0.14 2004/02/25
198 Fixes for Chunked encoding. White space not ignored after length spec.
200 Update NS and use default NS for SRW diagnostic elements.
202 --- 2.0.13 2004/02/23
204 Implement ZOOM_resultset_cache_reset which resets record cache.
206 Implement ZOOM_resultset_sort which sorts a result set.
208 Implement chunked HTTP transfer.
210 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
212 --- 2.0.12 2004/02/16
214 Added member 'schema' to bend_explain_rr structure so that backend
215 can specify explain record identifier. Defaults to Zeerex 2.0.
217 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
219 --- 2.0.11 2004/02/16
221 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
224 Added init command for yaz-client which sends "extra" init request.
226 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
227 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
229 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
231 Make ZOOM error code for "invalid query".
233 Fixed compilation for SSL which wasn't properly enabled for all platforms.
235 --- 2.0.10 2004/02/05
237 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
240 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
242 Added option -p <file> to make Generic Frontend Server to write PID file.
244 Added option -D to put Generic Frontend Server in background on its own.
246 Make ZOOM C recognize option "password". If unset, "pass" is used
247 (for backwards compatibility).
249 Fixed a bug in Generic Frontend Server that could make it crash if a
250 client sets characterSetNegotation bit, but didn't pass negotiation stuff
253 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
254 Must be issued before open, in order to be in effect.
256 --- 2.0.9-6 2004/01/12 Debian/Windows
258 Make the SRU server more picky WRT unknown params, etc.
260 Bug fix: ZOOM scan response didn't return displayTerm - when present.
262 New YAZ client command, options, that sets Z39.50 options.
264 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
265 options from a string of tokens (one token for each option bit).
267 Update SRW diagnostic code messages.
269 --- 2.0.9-5 2004/01/07 Debian/Windows
271 Handle user defined stylesheet for SRW/SRU.
273 --- 2.0.9-4 2004/01/06 Debian/Windows
275 Fix bug in decoding of Content-Length.
277 --- 2.0.9-3 2004/01/06 Debian/Windows
279 Fix a bug with decoding of XML packed records.
281 --- 2.0.9-2 2004/01/05 Debian only
283 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
285 Fix bug in SRW/SRU diagnostics decoding.
289 Fixed bug in Generic Frontend Server which could drop records exceeding
290 preferred message size. Reported and fixed by Irina Dijour.
292 Fixed calculation of package size for structured records in Generic
293 Frontend Server. Reported and fixed by Irina Dijour.
295 Fixed namespace for SRW/SRU diagnostics.
297 Fixed SEGV in yaz-client that occured for HTTP connection errors.
301 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
302 this version is incompatible with version 1.0 and older YAZ SRW/SRU
305 CQL changes to reflect recent changes to the specification:
306 * Documentation talks about context sets instead of index sets.
307 * Documentation talks about indexes instead of qualifiers.
308 * The CQL-to-PQF transformer's configuration file now uses
309 "index.set.name = <attributes>" instead of the old form
310 "qualifier.set.name = <attributes>". (Both forms are still
311 understood but the latter is deprecated.)
312 * CQL terms with no explicit index specified are now interpreted as
313 cql.serverChoice instead of srw.serverChoice (which of course
314 behaves exactly the same.)
318 MARC conversion can now generate ISO2709 output in another
319 character set. yaz-marcdump uses this facility if you invoke it
322 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
323 functions from there can be used from C++.
327 Frontend server now transfers memory from decoded packages to stream
330 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
331 references to show up.
333 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
334 the ZOOM Abstract API. The older names for the same options are still
335 also supported for the benefit of old applications.
337 ZOOM-C supports "implementationId" and "implementationVersion" options
338 to go along with "implementationName". These allow the user code to
339 specify identification strings to be sent to servers.
340 Add OID for the new ExtLite attribute set.
342 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
343 as requested/supplid by Ere Maijala <ere@atp.fi>
345 For generic frontend server, reverse the order of
346 "toolkit-supplied / application-supplied" strings sent as implementationId,
347 Name and Version. Also, remove the spaces around the slash. This brings
348 the GFS in line with the behaviour of ZOOM-C on the client side.
350 Add function ZOOM_scanset_display_term.
352 yaz-client shows scan displayTerm if present.
354 Utility yaz-iconv is now installed by default along with the man page
357 Extend configure check for OpenSSL to use pkg-config where available (such
360 Incorporate patch by Morten Bogeskov which allows a Unix file socket
361 server to specify uid/gid/mask for socket using the format
362 unix:[user=uid,][group=gid,][umask=mask,]file=path
363 If file= is omitted the existing format is assumed, e.g.
365 in which case the mask is 0666 (rw for everybody).
367 Major restructure of YAZ source. All source in libyaz is in src directory.
368 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
369 util (utility programs such as ASN.1 compiler, yaz-marcdump).
371 Added man page for utility yaz-marcdump (used to be called marcdump).
372 yaz-marcdump is installed by 'make install'.
374 Fixed a memory leak in Generic Frontend Server that occurred when decoding
375 of incoming package failed.
377 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
379 Change prototype of odr_perror: add const to message string.
381 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
383 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
384 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
385 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
386 DNS lookup. There should not be any compatibility problems with this
387 assuming that blocking=1 or 0 is used.
389 Fix bad reference in UNIX comstack in function cs_addrstr.
391 Fix for compilation on AIX.
393 The generic front-end server (server/seshigh.c) now supports returning
394 Init diagnostics to the client in User-information-field, in
395 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
400 Allow any CQL relation (not just all,any,exact,scr).
402 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
403 that features the same UI.
405 Implemented command update0 in YAZ client which is equivalent to
406 update but uses old of Ext Update ASN.1.
408 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
409 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
410 Previously no OID was used for this info.
412 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
413 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
414 returns 'malformed search term' otherwise.
416 SortResponse member resultCount now set to NULL in sort handler of
419 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
422 Add three new utility functions for translating OIDs between various
423 formats -- symbolic name such as "Usmarc", minus-1-terminated int
424 arrays and dotted strings such as "1.2.840.10003.9.5.1":
425 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
426 char *oid_to_dotstring(const int *oid, char *oidbuf);
427 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
429 Reverted modifications for ES Update definition for z_IU0Update
430 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
431 is back to YAZ 2.0.2.
433 String value attributes for CCL parser.
435 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
436 which their FirstSearch server returns in Init responses, sometimes
437 carrying useful diagnostic information when Init fails. This has the
438 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
439 "z39.50/oclcui.asn", where its definition is somewhat different from
440 what OCLC document on their web-site, as required to interoperate with
443 Support for anonymous authentication in yaz-client. Use the command
446 * Fix the OID of the Index Data-local "admin" Extended Service from
447 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
448 the 1000, which indicates a locally-defined OID, was a mistake.
452 Fix CCL directive @case handling so that it affects string match for
453 both CCL keywords and qualifiers.
455 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
456 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
457 Decoder has been updated with ASN.1 changes as listed in
458 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
459 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
460 z_IUUpdate, remains unchanged.
462 ZOOM_record_get may now return a record in a specific character set.
463 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
464 "from" is the character set of record as returned by target. "to" is
465 the character set to be returned. If omitted, "to" is UTF-8.
467 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
469 New ODR utility, odr_getelement, which returns name of element for
470 which encoding/decoding failed.
472 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
473 in cases where a required element was omitted.
475 Bug fix: some MARC8 sequences were not converted.
477 New ZOOM option "step" which specifies number of records to be
478 retrieved in one chunk. Used in conjunction with "start" and "count".
480 SRW support for yaz-client. Use scheme http: to use it, e.g.
483 yaz-client no longer does (un)intelligent character set conversions
484 by default. Can be enabled with charset and marc_charset commands.
486 xmalloc trace fix for 64-bit systems such as DEC alpha.
488 Solaris 2.6 compile fix.
490 New function, cql_strerror() translates SRW error codes, as returned
491 by cql_transform_error(), into human-readable English strings. Used
492 in yaz-client diagnostics when appropriate.
494 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
495 converts it into a type-1 query which is sent to the server. This
496 makes CQL available for use with all Z-servers, as opposed to the tiny
497 minority that can handle CQL queries themselves.
501 New Debian package layout similar to the Redhat Package layout.
503 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
504 and search result respectively.
508 Redhat package is now several packages: libyaz (runtime libraries),
509 libyaz-devel (development and documentation, and yaz (utility programs).
510 Package spec file by Morten Bøgeskov.
512 New member 'schema' in struct bend_fetch_rr which the name of requested
513 schema (SRW/SRU) for record (or NULL if none was given). The fetch
514 handler MAY set this to reflect the schema of the returned record.
516 New member 'display_term' in struct scan_entry. GFS now sets member entries
517 and allocates scan entries to be filled by user scan handler. In previous
518 version, entries member was allocated by the scan handler. That still works,
519 but the GFS will ignore member display_term - assuming it was NOT set by
520 the handler. The fact that the GFS now allocates the entries both allows
521 for new members and makes a scan handler easier to write.
523 Fix CQL lex buffer overflow.
525 SRW/SRU recordPacking. For SRW default recordPacking is string. For
526 SRU default recordPacking is string.
528 SRU protocol support for frontend server.
530 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
532 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
534 Added scan for the ZOOM shell (zoomsh).
538 * String Identifers for Schemas (Amendment 5).
539 http://lcweb.loc.gov/z3950/agency/amend/am5.html
540 Old definition for schema
541 Odr_oid *schema; /* OPT */
546 Z_InternationalString *uri;
547 #define Z_Schema_oid 1
548 #define Z_Schema_uri 2
551 * resultCount parameter to Sort Response (Amendment 1).
552 http://lcweb.loc.gov/z3950/agency/amend/am1.html
554 Support for SRW 1.0 over HTTP. This is an optional feature and
555 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
558 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
559 on the same port. SRW SearchRetrieveRequests are mapped
560 to bend_init,bend_search,bend_fetch,bend_close.
562 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
564 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
565 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
567 ZOOM connections are SRW based if schem http is used for hostname
568 in connect, e.g. z = ZOOM_connection_new("http://myserver");
569 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
571 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
572 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
573 distance=n, order=true/false, relation=le, prox unit=word. If
574 n is omitted, distance 1 is used.
576 Fixed problem with C compiler include path in wrong order.
578 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
579 on Solaris. Patch from Ko van der Sloot.
581 New MARC decode API. All new functions operate on a yaz_marc_t
582 handle. The most important new functions are: yaz_marc_create,
583 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
584 decode and destroy respectively. Decoder can produce formats
585 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
586 include/yaz/marcdisp.h.
588 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
589 to UTF-8, UCS-32, wchar_t or Latin-1.
591 * Prototypes for yaz_iconv_-functions moved to separate header
592 include/yaz/yaz-iconv.h.
594 Make a few private functions 'static' in unix.c. This prevents
595 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
597 For ZOOM connection, the options targetImplementation{Id,Name,Version}
598 are set when Init Response is received.
600 New function ZOOM_connection_error_x similar to ZOOM_connection_error
601 but returns diagnostic set as well.
603 New function yaz_strerror which is a portable wrapper for
604 strerror/strerror_r/GetLastMessage.
606 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
607 is returned for MARC. If type is "oai", then OAI MARC is returned.
609 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
614 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
616 Fix bad race conditions on SIGTERM and terminate gracefully in
619 Move retrieval (data1) module to Zebra since nobody seems to be
622 Add GRS-1 render for ZOOM using same format as yaz-client.
626 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
628 Fix broken ESpec handling in data1 module.
630 SGML reader parses comments and makes them part of the data1 tree.
632 Added several type casts so that YAZ compiles as C++ code.
634 ZOOM didn't handle PDU encoding failures properly.
636 Added more Bib-1 diagnostics (approved extensions).
638 GNU configure: better check for iconv.
640 More portable use of accept, getpeername. Check for socklen_t. Use
641 int/size_t if socklen_t is not defined.
645 PQF parser rejects bad queries - including those with extra
646 characters in them. PQF parser used to silently ignore that.
647 Cleaner API for PQF added, which allows you to get detailed
648 error information for bad queries (see yaz/pquery.h).
650 Fixed bug in ZOOM_record_get for type "database".
652 Implemented mini iconv library supporting conversions between
653 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
655 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
659 Fixed ZOOM C record cache so that preferredRecordSyntax and
660 elementSetName is used to check for already fetched records.
664 Added three members in bend_initrequest structure to facilitate
665 character set negotiation.
667 Fixed a bug in frontend server that could cause indefinite
668 loops under rare conditions.
670 Revised character set utilities (charneg.h) so that encoding
671 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
673 For PQF, directive @term <type> sets term type for Scan/Search.
674 Here <type> is general, string, numeric, null. The term type
675 is inherited - just like @attr.
677 New call odr_set_charset that sets character set conversion for
678 international-strings on a ODR stream. Prototype is:
679 int odr_set_charset(ODR o, const char *to, const char *from);
680 The InternationalString is still represented as C string in YAZ
681 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
682 won't). On the protocol level, you can use any encoding.
684 Support for UNIX sockets in ZOOM.
686 Solaris recv sometimes returns errno == ENOENT. It is treated as
687 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
689 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
690 both client and server. Code by Morten Bøgeskov.
694 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
695 that they can be used directly from Visual Basic. You must recompile
696 your windows APP if you're using ZOOM.
698 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
699 Commands "lang" and "charset" sets language and character set respectively.
700 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
701 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
703 Attributes from multiple CCL fields may be OR'ed rather than merged
704 using directive "@field or". Fields are still merged by default -
705 equivalent to "@field merge".
707 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
710 Fixed bug in zget for parameter ExtendedServicesResponse.
716 Added PQF feature: '@attr type=value' may be written as '@type=value'.
718 Client displays USR.1:SearchResult-1 (hits per term).
720 Additional Search Info for search in Generic Frontend Server.
722 Fixed CCL parsing of "field=s".
724 WIN32 installer - using the excellent NSIS software from nullsoft.
726 Fixed CCL parsing of "field = - <number>".
728 Added function yaz_marc_decode that decodes MARC for line mode
729 display or XML (similar to that used by JZKit).
731 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
732 Z39.50. But ISO/ILL was, however.
734 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
735 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

742 New YAZ client features: Command completion and new commands:
743 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
744 Code provided by Jacob Poulsen.
746 New call oid_trav, that visits all registered OIDs via callback.
748 Function ZOOM_record_get now returns const char pointer rather than
749 void pointer. It saves a lot of type casts.
751 For YAZ client, command "auth" now allows you to set authentication
752 in IdPass style. It is enabled when three tokens are given - order
753 is user, group and password.
755 Fix memory leaks in MARC record handling for ZOOM.
757 New option for YAZ client, -k <kilobytes> that sets
758 maximum record size. Similar to -k option for generic frontend
759 server and yaz-ztest.
761 More fixes for scan. Non-zero stepSize handled. OID's fixes.
763 Prefix query parser reports "fail" when bad attribute set is given.
765 Fix in MARC decoder. Proximity logging. Fix for attribute set
766 in scan handler for server. Patches by Shigeru Ishida.
768 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
771 Configure option --with-openssl=<dir> now works when a directory is
772 specified. Patch provided by Morten Bøgeskov.
774 New option for YAZ client, -u <auth>, that sets authentication.
776 ZOOM fix: error information was sometimes "missing", since error
777 was cleared/reset too when it shouldn't.
779 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
783 Scan for ZOOM API. New object ZOOM_scanset. New functions
784 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
785 ZOOM_scanset_destroy.
787 New ZOOM function, ZOOM_connection_last_event, that returns type
788 of last event (such as "receive data", "send data", "apdu received",
791 New ZOOM option, schema, that specifies schema for retrieval.
793 New CCL feature. Qualifiers can be aliases for one or more
794 other qualifiers (if more than one is given, OR is used).
796 ZOOM uses named result sets if target supports it.
798 Two new YAZ client commands: . (dot, which sources a script of YAZ
799 client commands), and ! (to execute shell command.). Implemented
802 Working on Debian packages.
806 YAZ client enables named result sets only if target supports it.
808 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
810 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
811 with key="host" to get same result.
813 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
814 Function Z3950_resultset_record(s) returns references to records
815 "owned" by resultset. To become owner use Z3950_record_clone.
817 Function z_ext_record handles Extended Services. Thanks to
822 CCL Parser fix: ignore token comma when dealing with and-lists.
824 Documentation updates for COMSTACK.
826 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
827 Changed prototype Z3950_records. For some functions, int parameters
828 were changed to size_t.
830 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
833 New MARC decode/display function, marc_display_exl, which properly rejects
834 non-ISO2709 records. YAZ client uses it.
838 Fix bug: local attribute set wasn't set correctly in PQF strings.
842 * Old Z39.50 codecs no longer supported.
844 Added ZOOM C binding. See http://zoom.z3950.org/
846 Renamed states for COMSTACKs to avoid confusion with events.
848 Implemented cs_look and proper cs_rcvconnect.
850 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
852 Configure detects POSIX threads on OpenBSD.
854 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
855 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
857 When error is returned from present handler, non-surrogate diagnostic
858 is returned in present response (and fetch handler is no longer called).
860 * Minor adjustments to pquery parser (PQF). Token characters may be
861 escaped by using backslash (C-style).
863 PQF parser allows string attribute values to be specified. For @attr,
864 non-numeric characters after the equal-sign are treated as strings
865 (e.g. @attr 9=title).
867 CCL trunction character may be defined (@truncation in file)
869 * function zget_ExtendedServicesRequest sets waitAction to
870 waitIfPossible (was wait).
872 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
875 CCL operator names may be set in field definition files (CCL_bibset).
876 See ccl/bib1 for an example.
878 Fixes in ASN.1 compiler for C++ compatibility.
880 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
881 and "op_or" to avoid conflict with C++.
883 Fixed problem with GNU readline detection on Redhat 7.0.
885 Added step-size for Scan backend handler.
887 Fixed bug that made the frontend server crash when no attribute
888 set was specified for scan.
890 Front-end server automatically switches to original working directory
891 when installed as an NT service. Previously -w had to be specified to
894 Added extended attributes for retrieval module (data1), so that data1
895 records carry d1_readXML/SGML attributes. d1_read also supports
896 null-data rules ( <tag/>)
898 On UNIX when POSIX threads are available, a separate library libyazthread
899 is created. Programmers should link with that library and the yaz library
900 when using threads. The reason for the split was that some applications
901 on Linux, such as Apache, doesn't work well when using shared objects that
904 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
905 (or any frontend server) in SSL mode by specifying ssl: followed by
906 address. Only tested on UNIX.
908 Added feature for CCL module. Virtual structure s=al or s=ol generates
909 and-list and or-list respectively instead of phrase search.
913 * Added prefix "yaz_" for the functions log_init.., log_file.. and
914 log_mask_str. This was done to avoid name conflicts with other libraries
915 (such as other PHP extensions).
917 Added raw OID member for preferred record syntax (request_format_raw)
918 and returned record syntax (output_format_raw) for backend fetch method.
920 Config file yaz-config now accepts options so that it returns specific
921 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
923 Shared library support for UNIX using GNU libtool.
925 * Modified backend interface. Request/Response struct's replaced by
926 one read/write C struct. For example bend_fetchrequest and
927 bend_fetchresult have been replaced by single bend_fetch_rr struct.
928 Every handler - even search has to be registered in bend_init
929 handler. This means that the YAZ library no longer refers to
930 external functions and it makes it possible to make the whole
931 thing a single DLL/SO.
933 Added Segment handler for backend server.
935 Added Zmbol/Zebra administrative functions to YAZ client.
937 Threaded frontend server on UNIX (when POSIX Threads are available).
938 Starting the server with option -T enables multi-threading.
942 Added configure option --enable-comp/disable-comp to control use
943 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
944 located in sub directory asn.
946 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
947 in ${exec_prefix}/bin along with the other programs yaz-client and
950 GNU automake used to maintain makefiles.
954 Changed retrieval module so that we can load records with no abstract
955 syntax defined. Tagpaths in these records are fully composed of string
958 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
962 On UNIX, the generated makefile now supports a proper 'make install'.
963 The prefix can be set via GNU configure to set the install location
964 (default is /usr/local).
966 * YAZ programs client and ztest were renamed to yaz-client and
967 yaz-ztest to avoid conflicts when users install YAZ in "standard"
968 locations, such as /usr/bin,/usr/local/bin,etc.
970 * YAZ Header files were moved from include to include/yaz. YAZ Header
971 files are referred to as include <yaz/log.h> rather than <log.h>.
972 The YAZ include path (-I ..) is therefore the same as before. Programmers
973 should update their #include statements or use -Ipath/include/yaz
974 instead. The main motivation for doing this change is that YAZ header files
975 can be installed in "standard" locations /usr/include,/usr/local/include
976 without introducing conflicts, since ALL YAZ header files are stored
977 in subdirectory yaz (under /usr/include for example).
979 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
980 rather than project/workspace files. We switched because project files
981 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
984 Changed name of logging function, logf, to yaz_log, to prevent name
985 clash with some math-log functions. The YAZ header log.h defines logf
986 to yaz_log (#define) so there should be no incompatibilities by this
989 Added bend_start/bend_stop handlers for server. These handler are
990 called on start/stop of server. For windows they are called whenever
991 a service is started/stopped.
993 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
994 a fairly small ASN.1 compiler written in Tcl. The compiler is located
995 in util/yc.tcl. The auto-generated C code structures are, in a few
996 cases, incompatible with the old decoders. There are differences in the
997 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
998 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
999 The preprocessor variable ASN_COMPILED is defined when the compiled
1000 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1001 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1002 wish to use the old encoders/decoders you can specify --disable-yc
1005 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1006 version so that it supports both new - and old version of DB Update
1008 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1009 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1010 change. The name parameter can be set to 0 in which no name is specified
1011 for the construction. The macros odr_implicit and odr_explicit sets name
1012 parameter to zero for the construction involved. New macros
1013 odr_implicit_tag and odr_explicit_tag are similar to the others,
1014 except that a name parameter is added. For programmers' that don't use
1015 ODR they probably only need to change the call to z_APDU and z_External.
1017 Added access control facility by interfacing the TCP wrapper library.
1018 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1019 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1020 name of the daemon and enables the access control as specified in
1021 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1023 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1024 den Dool <H.M.vdnDool@kub.nl>.
1026 Added reference ID parameter to most functions in server API - refer
1027 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1029 Changed name of ccl library to libccl.a (was ccl.a).
1031 Fixed bug in decoder for Explain (Category TargetInfo).
1033 Added support for GNU readline in client. Thanks to Jacob Poulsen
1034 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1036 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1037 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1038 IMPLEMENTATION! This change was made to the development version before
1039 the ZIG decided to retract the amendment. If any users MUST be
1040 compatible with the original Update definition, PLEASE CONTACT US, and
1041 we will include a separate definition corresponding to the old Update
1042 ES. Note that because of the change to the ASN.1 of the
1043 TaskPackageRecordStructure we cannot define a single structure that
1044 will support both versions.
1046 * Added const modifier to buffer parameter for some ODR/BER encoding
1047 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1048 completeWAIS, odr_dumpBER.
1050 Fixed bug in client.c which caused a crash when a scanResponse didn't
1051 contain positionOfTerm.
1053 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1054 * will cause an error in a client if a non-YAZ target sends both a
1055 * list of Scan entries and non-surrogate diagnostics.
1057 Retrieval module enhancements. Tag sets may be typed in the reference
1058 to it. From the .abs-file the "tagset" directive takes a third optional
1059 integer type for the tag set referenced. From a .tag-file the "include"
1060 directive takes a third optional type as well. The old "type" directive
1061 in the tag set itself is still recognized but acts as the default type
1064 Backend interface change. Individual Scan terms returned from bend_scan
1065 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1066 in include/backend.h.
1068 Retrieval module enhancements. Multiple tag sets and attribute sets may
1069 be specified in abstract syntax specs. Revised the error/warning for
1070 logging messages reported by the retrieval module when reading the
1073 Object Identifier system (oid_..) changed. The API is backwards
1074 compatible but the oid-routines now allocates new OID's when needed.
1075 Raw OID's may be specified in oid_getvalbyname.
1077 YAZ now uses GNU configure to generate Makefile(s).
1079 * Minor changes in some of the member names of DeleteResultSetRequest and
1080 DeleteResultSetResponse. See include/proto.h.
1082 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1083 and added member 'languages' in TargetInfo (which was missing).
1085 Changed the way attribute sets are handled in the retrieval
1086 module. These are now cached, just like the abstract syntaxes
1089 Changed YAZ so that it links with compiled ASN.1.
1091 Added Explain-schema definitions and mapping routines. The following
1092 Explain categories have been implemented: AttributeDetails,
1093 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1095 Fixed minor bug in Windows version of Server Library.
1097 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1099 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1101 Added EXTERNAL: UNIverse Resource Report (non-standard).
1103 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1104 ENUMERATED and SET OF.
1106 * Added 'const' to some of the char pointer arguments for the
1107 functions, data1_read_node, data1_getelementbytagname,
1108 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1111 Fixed bug in data1_insert_taggeddata - the last_child member of
1112 parent wasn't initialised.
1114 * Changed data1_read_record and data1_read_node so that the supplied
1115 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1116 doesn't refer to any parts of the "SGML"-buffer.
1118 Fixed bug in server library (Windows version of statserv_remove).
1120 * Changed code so that it compiles as C++. The type definition
1121 of Odr_fun which is a member of Odr_arm was changed. The result is,
1122 that an explicit typecast is needed for the fun pointer when
1123 using Odr_arm - as in:
1124 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1126 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1128 Implemented the new structured date and time definition as approved
1129 by the ZIG. Added schemaId element to the specificTag in Espec-1
1130 (also approved at the last ZIG). Thanks to RVDM.
1132 Added some Object identifiers (RVDM).
1134 Changed the Update Extended Service (RVDM).
1136 Added command "refid" to client which specifies referenceId for
1137 the following requests.
1139 Implemented extended service handling for server. See ztest.c
1140 for an example as well as backend.h. New handlers are registerd
1141 in the Init handler.
1143 * Changed interface for sort in server.
1145 Added new members to statserv_options_block. It allows a server
1146 to read options from another source than just the command line. Thanks
1147 to Charles Woodfield.
1149 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1150 renamed to zboolean. Some C++ compilers complained about the name.
1152 Minor changes to gils.abs. Added index 's' (sort) on title
1153 and date/time-last-modified.
1155 --- 1.4pl2 1998/1/30
1157 Fixed bug in server library regarding inetd mode (-i). This bug
1158 was introduced by release 1.4.
1160 --- 1.4pl1 1998/1/29
1162 Added sort facility in client and backend server interface.
1164 Fixed problem with dependencies in Makefile(s).
1166 Fixed bugs for encoders/decoders of extended services and
1169 Implemented sub-tree feature for schemas. Sub-trees are
1170 referenced in *.abs-files. See explain.abs for an example
1171 of the use of this feature.
1173 Modified bib1.att; local attributes for ANY didn't include
1174 ANY itself (only affects use of the retrieval module).
1176 Fixed bug in plain SGML reader in function data1_read_node:
1177 tags with prefix "var" was incorrectly interpreted as variants.
1179 Added feature "sub-schemas" to enable references to - and definitions
1180 of - group of elements.
1182 * Removed member parent from type data1_element (in data1.h).
1184 Implemented function odr_nullval() that returns the value of
1187 * Removed member num_children from data1_node (in data1.h).
1189 Made NT service interface part of the server library. The
1190 function statserv_main uses the NT service when required and
1191 calls the statserv_start / statserv_close routines.
1193 Routine zget_SearchRequest and zget_PresentRequest fills
1194 resultSetName/Id member with "default" instead of "Default".
1196 Fixed memory leak in server. Request queue member wasn't freed.
1198 Fixed nmem_exit so that memory is freed.
1202 Revised the CCL parser utility to be thread safe.
1204 Added function, oid_ent_to_oid, to replace the function
1205 oid_getoidbyent, which is not thread safe.
1207 * Added nmem_init and nmem_exit to initialize and release
1208 NMEM resources. Function nmem_init should be called once in the
1209 initial thread before NMEM/ODR is used. statserv.c and client.c
1210 have been changed accordingly. The change was necessary to make
1211 NMEM thread safe. The NMEM memory pool is shared amongst threads
1212 in a process. Unix-based applications will still work fine without
1215 Added NT Services interface for the the Z39.50 (statserv) Server.
1216 Refer to the ztest.c source on the usage.
1218 Windows 95/NT port using MSVC5.0. Project files are included in the
1221 * Defined new 'global' handle for the retrieval (data1) system. The
1222 new handled, data1_handle, describes the state of the data1 system.
1223 This handle is passed as first argument to virtually all
1224 data1 related routines. The functions data1_create and data1_destroy
1225 creates and destroys a data1 handle respectively.
1227 Added ODR encode stream member to all backend request structures
1228 init, search, scan etc. This stream should be used to allocate all
1229 memory used for the response when thread safe operation is needed.
1231 Changed the comstack utility, cs_addstr, to be thread safe. The
1232 returned hostname string returned by the function is now part the
1235 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1236 function. The cs_straddr takes a COMSTACK handle as argument, so this
1237 function must be used after cs_create and before bind/connect.
1238 This function is thread safe.
1240 Moved test server to 'ztest' directory - generic server code still
1241 in 'server' directory.
1243 Made prefix query (pquery.c) utility thread safe.
1245 Added new function modifier YAZ_EXPORT to 'export' public DLL
1246 functions when using windows (see include/yconfig.h).
1248 Added definitions to the OID database (util/oid.c) (RVDM).
1250 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1252 Added call to ccl_rpn_delete in client program.
1254 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1255 release of RPN structure.
1257 Added support for C++, headers uses extern "C" for public definitions.
1258 With input from RVDM.
1260 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1261 Thanks to Ronald van der Meer (RVDM).
1263 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1265 Added support for private extensions to the OID database
1266 (oid_setprivateoids()). Thanks to RVDM.
1268 Added optional, physical ANY (key replication)
1270 Fixed null-reference problem in GRS-1 output filter.
1272 Proximity operator added to Prefix Query Format (PQF).
1274 In test client command "base" accepts multiple databases.
1276 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1280 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1282 Smallish bug-fixes in the new encoders/decoders (explain).
1284 Bug fixed in DeleteRequest.
1286 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1288 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1290 Added SOIF syntax (using private OID for now) to retrieval module and client.
1292 Added Update extended service.
1294 Added SearchResult-1 additional info structure.
1296 Added optional CCL (ISO8777) interpreter as separate module. Available
1299 --- 1.2 1996/6/10 (1st anniversary release)
1301 Added Summary record syntax. Lightly tested.
1303 Added OPAC record syntax. Untested.
1305 Added ResourceReport service encoders/decoders. Untested.
1307 Fixed bug in z_Unit - wrong tagging on unitSystem.
1309 Fixed bug in the DiagRecs decoder.
1311 Added options for max PDU size and session timeout to frontend-server.
1313 Added documentation of query-language parsers and other supporting utilities.
1315 [frontend-server] Added Attribute set to the bend_scanrequest API.
1317 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1318 surrogate diagnostics were generated.
1320 [retrieval] Allow multiple local values for attribute.
1322 [retrieval] Allow multiple attributes per element in .abs files. index type.
1324 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1326 --- 1.1pl2 1996/4/10
1328 Minor changes, mostly specific to Zebra's requirements (retrieval)
1332 Repaired bug in frontend server when running multiple listening
1333 endpoints in dynamic mode.
1335 z_External() now won't break if a known, ASN.1 value comes encapsulated
1336 in an octet-string. The value will pass through unmodified in an Odr_oct.
1338 Added a bit of code to the demo client to decode & display
1339 ASN.1-structured records represented in the octet-aligned branch of
1340 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1342 Added z_ext_getentbyref() to the ASN module. Doc updated.
1344 * Completed the SCAN definition in the ASN module. This may break SCAN
1345 code based on older YAZ-versions at compile-time. The fix is easy -
1348 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1349 under the SCAN definition. Remember to initialize this, server-people.
1351 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1352 that this does not extend to ODR and ASN.
1354 Comstack allows insertion of established socket (primarily for
1355 inetd-operation of servers). Doc updated.
1357 Front-end server can now start from the inetd in TCP mode. Doc
1360 --- 1.0pl4 1996/1/24
1364 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1365 the rank and record number.
1367 Adjustments to the frontend server.
1369 Fixed diagnostic BER dumper. It ignored the file argument.
1373 Various changes to retrieval module.
1375 Changed the union discriminators of the protocol files from enums to
1376 ints paired with #defines.
1378 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1381 *Changed operator in the RPN structure to 'roperator', again to avoid a
1384 Fixed problems in Explain decoders/encoders.
1386 --- 1.0pl2 1995/12/6
1388 Memory bug in log module fixed.
1390 --- 1.0pl1 1995/12/5
1392 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1394 Bug in Explain DatabaseInfo module fixed.
1396 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1400 The shift to v1.0 signals that we now consider the *core* functionality
1401 of YAZ reasonably stable (the core being more or less equivalent to
1402 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1403 tested (Explain not at all - though that will happen soonish).
1405 Minor changes to code to support Windows port.
1407 Various minor changes after we're getting to use GRS-1 & co. more.
1409 Added Espec-1 format.
1411 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1412 of the protocol and it cannot be selected when encoding (maps into 'string'
1413 when decoding). Needed to talk to some servers.
1415 Demo client can request simple element set names.
1417 Added Diagnostic Format encoders/decoders.
1419 Added simple Close handling to frontend server (no hooks for resource
1420 reporting yet), and demonstration client.
1422 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1424 --- 1.0b3 1995/08/24
1426 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1427 handled incorrectly when records were requested in the searchResponse. This
1428 will only affect you if you use the frontend-server.
1430 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1431 Test-client will ask for and print GRS1. Ztest will return dummy records
1434 Added Explain encoders/decoders to the service-level API. Untested.
1436 Added Extended Services: Item Order encoders and decoders to the Service-
1437 level API. Untested. We could use a recent copy of the pertinent bits
1438 of the ILL protocol to add those bits.
1440 Added diagnostic format 1 encoders/decoders to the service-level API.
1443 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1444 odr_cons.c, which causes a more correct output.
1446 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1447 was always set to 0 when no records were requested in the searchRequest.
1449 * Added better external-handling. This shouldn't harm old code that
1450 *encodes* externals. It can break code that looks for a
1451 'single-ASN1-type' representation, since those types that are known
1452 are now decoded immediately. Look at the SUTRS sample code in
1453 seshigh.c and client.c. Documentation updated.
1455 Handling of structured records in bend_fetchresponse. Length -1 marks
1456 structured record, type is deduced from format field.
1458 --- 1.0b2 1995/06/27
1459 Fairly quick maintenance release to add SUTRS support.
1461 Fixed handling of SUTRS records in the demonstration client.
1463 * Added format field to the bend_fetchrequest and bend_fetchresponce
1464 structures of the backend API (frontend server). When the record is
1465 returned, the value of the format field is mapped to an OID. The
1466 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1467 of the record. The special value VAL_NONE in the bend_request means
1468 that no specific format was requested by the client. Documentation
1469 updated accordingly. Test server (ztest) will return a fixed dummy
1470 SUTRS record if your client requests SUTRS.
1472 Documentation updated accordingly.
1474 You can now set external libraries and RANLIB support in the top-level
1478 First public release.
