1 Possible compatibility problems with earlier versions marked with '*'.
5 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
6 instead of LOG_, due to name clash with syslog(3). LOG_ are still
7 present. New applications should define YAZ_USE_NEW_LOG=1 - this
8 will effectively disable old definitions.
12 Added yaz_log_time_format which specifies log format using
15 Added yaz_log_module_level which returns mask for a module. Value
16 is non-zero mask a if module is enabled; zero if disabled.
18 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
21 Fixed bug #176: Dont throw diagnostics on empty SRU args.
23 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
25 Fixed bug #172: RPM builds does not enable SSL.
27 Doxyfile.in part of dist. Doxyfile generated by configure.
29 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
30 are given and the corresponding component does not exist.
32 Extend CCL documentation in YAZ reference. Describe r=r.
36 Fixed MARC->MARCXML conversion to properly deal with
37 fields, subfields, indicators having non-ASCII characters.
39 Fixed MARC->MARCXML conversion so that ASCII control characters
40 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
43 Added YAZ GFS support for conversion from Z39.50 surrogate
44 diagnostics to SRW surrogate diagnostics.
46 Bug fix: YAZ GFS did not return schema in explainResponse.
50 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
51 now converts recordSchema to elementSetName as well as schema URI.
53 Fixed bug in COMSTACK that prevented HTTP request packages from being
58 Added CCL facility r=r "range" which is similar to r=o "ordered" but
59 does not require white-space before and after the dash in a range, e.g.
60 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
63 Fixed a few AC_TRY_LINK configure tests that did not operate properly
64 due to new GCC removing "redundant" code.
66 Added yaz-client commands scanpos and scanstep that sets preferred
67 position and step-size for scan.
69 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
71 Added CCL utility ccl_qual_buf which parses one or more CCL
72 spec lines in a buffer.
74 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
75 of name and value - ignoring empty lines and comments.
77 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
79 Added odr_get_element_path which returns current element path for an
80 ODR handle. This utility is useful in error handling or user-defined
83 Added ODR_PRINT utility odr_set_stream which is is a more generic
84 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
85 to a write function and pointer to close function. The close function - if
86 non-NULL - will be called during odr_destroy.
88 Fixed bug in CCL parser where truncation char was not removed from
89 right side when truncation=both was in effect.
91 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
96 Fix buffer overrun in CQL parser when dealing with proximity (%).
98 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
99 to UTF-8/UCS conversion is now only based on codetables.xml.
101 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
103 --- 2.0.22 2004/08/06
105 Add support for more "commit changes" in ZOOM (uses Extended Services).
107 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
110 Yet another small fix for configure of SSL.
112 --- 2.0.21 2004/05/14
114 Fix SSL libs for configure when --with-openssl=DIR is given.
116 --- 2.0.20 2004/05/10
118 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
120 SSL comstack now uses yaz.pem certificate file on server side
121 by default. Certificate filename can be configured by calling
122 comstack function cs_set_ssl_certificate_file before cs_bind is used.
124 Fix bug regarding multiple calls to ZOOM_connection_connect.
126 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
128 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
129 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
131 ZOOM now allows inspection of X509 peer certificate for verification.
132 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
134 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
135 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
136 as "modular" but it simplifies things.
138 Added cs_get_peer_certificate to that returns peer X509 PEM.
140 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
141 NULL if SSL is unavailable.
143 Documentation about MARC decoding tools.
145 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
147 --- 2.0.19 2004/03/30
149 Rename CHANGELOG to NEWS to follow GNU style packing.
151 Fix bug with missing initialization of member in init_diagnostics.
152 This bug affects threaded version of GFS server.
154 --- 2.0.18 2004/03/20
156 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
159 Ensure zlib.dll is packed with Windows install.
161 --- 2.0.17 2004/03/17
163 Fix encoding of xsd:string to use text instead of CDATA.
165 Fix endless loop in CQL parser with unbalanced ".
167 Use a more compact way to store MARC-8 conversion tables.
169 --- 2.0.16 2004/03/16 Debian only
171 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
174 Update CQL parser to use new CQL 1.1 modifiers for booleans and
179 --- 2.0.15 2004/03/01
181 Another fix for decoding of XML packed records.
183 --- 2.0.14 2004/02/25
185 Fixes for Chunked encoding. White space not ignored after length spec.
187 Update NS and use default NS for SRW diagnostic elements.
189 --- 2.0.13 2004/02/23
191 Implement ZOOM_resultset_cache_reset which resets record cache.
193 Implement ZOOM_resultset_sort which sorts a result set.
195 Implement chunked HTTP transfer.
197 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
199 --- 2.0.12 2004/02/16
201 Added member 'schema' to bend_explain_rr structure so that backend
202 can specify explain record identifier. Defaults to Zeerex 2.0.
204 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
206 --- 2.0.11 2004/02/16
208 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
211 Added init command for yaz-client which sends "extra" init request.
213 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
214 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
216 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
218 Make ZOOM error code for "invalid query".
220 Fixed compilation for SSL which wasn't properly enabled for all platforms.
222 --- 2.0.10 2004/02/05
224 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
227 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
229 Added option -p <file> to make Generic Frontend Server to write PID file.
231 Added option -D to put Generic Frontend Server in background on its own.
233 Make ZOOM C recognize option "password". If unset, "pass" is used
234 (for backwards compatibility).
236 Fixed a bug in Generic Frontend Server that could make it crash if a
237 client sets characterSetNegotation bit, but didn't pass negotiation stuff
240 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
241 Must be issued before open, in order to be in effect.
243 --- 2.0.9-6 2004/01/12 Debian/Windows
245 Make the SRU server more picky WRT unknown params, etc.
247 Bug fix: ZOOM scan response didn't return displayTerm - when present.
249 New YAZ client command, options, that sets Z39.50 options.
251 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
252 options from a string of tokens (one token for each option bit).
254 Update SRW diagnostic code messages.
256 --- 2.0.9-5 2004/01/07 Debian/Windows
258 Handle user defined stylesheet for SRW/SRU.
260 --- 2.0.9-4 2004/01/06 Debian/Windows
262 Fix bug in decoding of Content-Length.
264 --- 2.0.9-3 2004/01/06 Debian/Windows
266 Fix a bug with decoding of XML packed records.
268 --- 2.0.9-2 2004/01/05 Debian only
270 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
272 Fix bug in SRW/SRU diagnostics decoding.
276 Fixed bug in Generic Frontend Server which could drop records exceeding
277 preferred message size. Reported and fixed by Irina Dijour.
279 Fixed calculation of package size for structured records in Generic
280 Frontend Server. Reported and fixed by Irina Dijour.
282 Fixed namespace for SRW/SRU diagnostics.
284 Fixed SEGV in yaz-client that occured for HTTP connection errors.
288 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
289 this version is incompatible with version 1.0 and older YAZ SRW/SRU
292 CQL changes to reflect recent changes to the specification:
293 * Documentation talks about context sets instead of index sets.
294 * Documentation talks about indexes instead of qualifiers.
295 * The CQL-to-PQF transformer's configuration file now uses
296 "index.set.name = <attributes>" instead of the old form
297 "qualifier.set.name = <attributes>". (Both forms are still
298 understood but the latter is deprecated.)
299 * CQL terms with no explicit index specified are now interpreted as
300 cql.serverChoice instead of srw.serverChoice (which of course
301 behaves exactly the same.)
305 MARC conversion can now generate ISO2709 output in another
306 character set. yaz-marcdump uses this facility if you invoke it
309 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
310 functions from there can be used from C++.
314 Frontend server now transfers memory from decoded packages to stream
317 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
318 references to show up.
320 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
321 the ZOOM Abstract API. The older names for the same options are still
322 also supported for the benefit of old applications.
324 ZOOM-C supports "implementationId" and "implementationVersion" options
325 to go along with "implementationName". These allow the user code to
326 specify identification strings to be sent to servers.
327 Add OID for the new ExtLite attribute set.
329 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
330 as requested/supplid by Ere Maijala <ere@atp.fi>
332 For generic frontend server, reverse the order of
333 "toolkit-supplied / application-supplied" strings sent as implementationId,
334 Name and Version. Also, remove the spaces around the slash. This brings
335 the GFS in line with the behaviour of ZOOM-C on the client side.
337 Add function ZOOM_scanset_display_term.
339 yaz-client shows scan displayTerm if present.
341 Utility yaz-iconv is now installed by default along with the man page
344 Extend configure check for OpenSSL to use pkg-config where available (such
347 Incorporate patch by Morten Bogeskov which allows a Unix file socket
348 server to specify uid/gid/mask for socket using the format
349 unix:[user=uid,][group=gid,][umask=mask,]file=path
350 If file= is omitted the existing format is assumed, e.g.
352 in which case the mask is 0666 (rw for everybody).
354 Major restructure of YAZ source. All source in libyaz is in src directory.
355 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
356 util (utility programs such as ASN.1 compiler, yaz-marcdump).
358 Added man page for utility yaz-marcdump (used to be called marcdump).
359 yaz-marcdump is installed by 'make install'.
361 Fixed a memory leak in Generic Frontend Server that occurred when decoding
362 of incoming package failed.
364 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
366 Change prototype of odr_perror: add const to message string.
368 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
370 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
371 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
372 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
373 DNS lookup. There should not be any compatibility problems with this
374 assuming that blocking=1 or 0 is used.
376 Fix bad reference in UNIX comstack in function cs_addrstr.
378 Fix for compilation on AIX.
380 The generic front-end server (server/seshigh.c) now supports returning
381 Init diagnostics to the client in User-information-field, in
382 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
387 Allow any CQL relation (not just all,any,exact,scr).
389 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
390 that features the same UI.
392 Implemented command update0 in YAZ client which is equivalent to
393 update but uses old of Ext Update ASN.1.
395 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
396 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
397 Previously no OID was used for this info.
399 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
400 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
401 returns 'malformed search term' otherwise.
403 SortResponse member resultCount now set to NULL in sort handler of
406 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
409 Add three new utility functions for translating OIDs between various
410 formats -- symbolic name such as "Usmarc", minus-1-terminated int
411 arrays and dotted strings such as "1.2.840.10003.9.5.1":
412 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
413 char *oid_to_dotstring(const int *oid, char *oidbuf);
414 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
416 Reverted modifications for ES Update definition for z_IU0Update
417 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
418 is back to YAZ 2.0.2.
420 String value attributes for CCL parser.
422 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
423 which their FirstSearch server returns in Init responses, sometimes
424 carrying useful diagnostic information when Init fails. This has the
425 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
426 "z39.50/oclcui.asn", where its definition is somewhat different from
427 what OCLC document on their web-site, as required to interoperate with
430 Support for anonymous authentication in yaz-client. Use the command
433 * Fix the OID of the Index Data-local "admin" Extended Service from
434 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
435 the 1000, which indicates a locally-defined OID, was a mistake.
439 Fix CCL directive @case handling so that it affects string match for
440 both CCL keywords and qualifiers.
442 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
443 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
444 Decoder has been updated with ASN.1 changes as listed in
445 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
446 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
447 z_IUUpdate, remains unchanged.
449 ZOOM_record_get may now return a record in a specific character set.
450 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
451 "from" is the character set of record as returned by target. "to" is
452 the character set to be returned. If omitted, "to" is UTF-8.
454 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
456 New ODR utility, odr_getelement, which returns name of element for
457 which encoding/decoding failed.
459 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
460 in cases where a required element was omitted.
462 Bug fix: some MARC8 sequences were not converted.
464 New ZOOM option "step" which specifies number of records to be
465 retrieved in one chunk. Used in conjunction with "start" and "count".
467 SRW support for yaz-client. Use scheme http: to use it, e.g.
470 yaz-client no longer does (un)intelligent character set conversions
471 by default. Can be enabled with charset and marc_charset commands.
473 xmalloc trace fix for 64-bit systems such as DEC alpha.
475 Solaris 2.6 compile fix.
477 New function, cql_strerror() translates SRW error codes, as returned
478 by cql_transform_error(), into human-readable English strings. Used
479 in yaz-client diagnostics when appropriate.
481 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
482 converts it into a type-1 query which is sent to the server. This
483 makes CQL available for use with all Z-servers, as opposed to the tiny
484 minority that can handle CQL queries themselves.
488 New Debian package layout similar to the Redhat Package layout.
490 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
491 and search result respectively.
495 Redhat package is now several packages: libyaz (runtime libraries),
496 libyaz-devel (development and documentation, and yaz (utility programs).
497 Package spec file by Morten Bøgeskov.
499 New member 'schema' in struct bend_fetch_rr which the name of requested
500 schema (SRW/SRU) for record (or NULL if none was given). The fetch
501 handler MAY set this to reflect the schema of the returned record.
503 New member 'display_term' in struct scan_entry. GFS now sets member entries
504 and allocates scan entries to be filled by user scan handler. In previous
505 version, entries member was allocated by the scan handler. That still works,
506 but the GFS will ignore member display_term - assuming it was NOT set by
507 the handler. The fact that the GFS now allocates the entries both allows
508 for new members and makes a scan handler easier to write.
510 Fix CQL lex buffer overflow.
512 SRW/SRU recordPacking. For SRW default recordPacking is string. For
513 SRU default recordPacking is string.
515 SRU protocol support for frontend server.
517 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
519 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
521 Added scan for the ZOOM shell (zoomsh).
525 * String Identifers for Schemas (Amendment 5).
526 http://lcweb.loc.gov/z3950/agency/amend/am5.html
527 Old definition for schema
528 Odr_oid *schema; /* OPT */
533 Z_InternationalString *uri;
534 #define Z_Schema_oid 1
535 #define Z_Schema_uri 2
538 * resultCount parameter to Sort Response (Amendment 1).
539 http://lcweb.loc.gov/z3950/agency/amend/am1.html
541 Support for SRW 1.0 over HTTP. This is an optional feature and
542 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
545 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
546 on the same port. SRW SearchRetrieveRequests are mapped
547 to bend_init,bend_search,bend_fetch,bend_close.
549 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
551 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
552 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
554 ZOOM connections are SRW based if schem http is used for hostname
555 in connect, e.g. z = ZOOM_connection_new("http://myserver");
556 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
558 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
559 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
560 distance=n, order=true/false, relation=le, prox unit=word. If
561 n is omitted, distance 1 is used.
563 Fixed problem with C compiler include path in wrong order.
565 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
566 on Solaris. Patch from Ko van der Sloot.
568 New MARC decode API. All new functions operate on a yaz_marc_t
569 handle. The most important new functions are: yaz_marc_create,
570 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
571 decode and destroy respectively. Decoder can produce formats
572 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
573 include/yaz/marcdisp.h.
575 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
576 to UTF-8, UCS-32, wchar_t or Latin-1.
578 * Prototypes for yaz_iconv_-functions moved to separate header
579 include/yaz/yaz-iconv.h.
581 Make a few private functions 'static' in unix.c. This prevents
582 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
584 For ZOOM connection, the options targetImplementation{Id,Name,Version}
585 are set when Init Response is received.
587 New function ZOOM_connection_error_x similar to ZOOM_connection_error
588 but returns diagnostic set as well.
590 New function yaz_strerror which is a portable wrapper for
591 strerror/strerror_r/GetLastMessage.
593 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
594 is returned for MARC. If type is "oai", then OAI MARC is returned.
596 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
601 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
603 Fix bad race conditions on SIGTERM and terminate gracefully in
606 Move retrieval (data1) module to Zebra since nobody seems to be
609 Add GRS-1 render for ZOOM using same format as yaz-client.
613 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
615 Fix broken ESpec handling in data1 module.
617 SGML reader parses comments and makes them part of the data1 tree.
619 Added several type casts so that YAZ compiles as C++ code.
621 ZOOM didn't handle PDU encoding failures properly.
623 Added more Bib-1 diagnostics (approved extensions).
625 GNU configure: better check for iconv.
627 More portable use of accept, getpeername. Check for socklen_t. Use
628 int/size_t if socklen_t is not defined.
632 PQF parser rejects bad queries - including those with extra
633 characters in them. PQF parser used to silently ignore that.
634 Cleaner API for PQF added, which allows you to get detailed
635 error information for bad queries (see yaz/pquery.h).
637 Fixed bug in ZOOM_record_get for type "database".
639 Implemented mini iconv library supporting conversions between
640 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
642 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
646 Fixed ZOOM C record cache so that preferredRecordSyntax and
647 elementSetName is used to check for already fetched records.
651 Added three members in bend_initrequest structure to facilitate
652 character set negotiation.
654 Fixed a bug in frontend server that could cause indefinite
655 loops under rare conditions.
657 Revised character set utilities (charneg.h) so that encoding
658 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
660 For PQF, directive @term <type> sets term type for Scan/Search.
661 Here <type> is general, string, numeric, null. The term type
662 is inherited - just like @attr.
664 New call odr_set_charset that sets character set conversion for
665 international-strings on a ODR stream. Prototype is:
666 int odr_set_charset(ODR o, const char *to, const char *from);
667 The InternationalString is still represented as C string in YAZ
668 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
669 won't). On the protocol level, you can use any encoding.
671 Support for UNIX sockets in ZOOM.
673 Solaris recv sometimes returns errno == ENOENT. It is treated as
674 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
676 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
677 both client and server. Code by Morten Bøgeskov.
681 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
682 that they can be used directly from Visual Basic. You must recompile
683 your windows APP if you're using ZOOM.
685 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
686 Commands "lang" and "charset" sets language and character set respectively.
687 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
688 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
690 Attributes from multiple CCL fields may be OR'ed rather than merged
691 using directive "@field or". Fields are still merged by default -
692 equivalent to "@field merge".
694 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
697 Fixed bug in zget for parameter ExtendedServicesResponse.
703 Added PQF feature: '@attr type=value' may be written as '@type=value'.
705 Client displays USR.1:SearchResult-1 (hits per term).
707 Additional Search Info for search in Generic Frontend Server.
709 Fixed CCL parsing of "field=s".
711 WIN32 installer - using the excellent NSIS software from nullsoft.
713 Fixed CCL parsing of "field = - <number>".
715 Added function yaz_marc_decode that decodes MARC for line mode
716 display or XML (similar to that used by JZKit).
718 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
719 Z39.50. But ISO/ILL was, however.
721 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
722 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

729 New YAZ client features: Command completion and new commands:
730 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
731 Code provided by Jacob Poulsen.
733 New call oid_trav, that visits all registered OIDs via callback.
735 Function ZOOM_record_get now returns const char pointer rather than
736 void pointer. It saves a lot of type casts.
738 For YAZ client, command "auth" now allows you to set authentication
739 in IdPass style. It is enabled when three tokens are given - order
740 is user, group and password.
742 Fix memory leaks in MARC record handling for ZOOM.
744 New option for YAZ client, -k <kilobytes> that sets
745 maximum record size. Similar to -k option for generic frontend
746 server and yaz-ztest.
748 More fixes for scan. Non-zero stepSize handled. OID's fixes.
750 Prefix query parser reports "fail" when bad attribute set is given.
752 Fix in MARC decoder. Proximity logging. Fix for attribute set
753 in scan handler for server. Patches by Shigeru Ishida.
755 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
758 Configure option --with-openssl=<dir> now works when a directory is
759 specified. Patch provided by Morten Bøgeskov.
761 New option for YAZ client, -u <auth>, that sets authentication.
763 ZOOM fix: error information was sometimes "missing", since error
764 was cleared/reset too when it shouldn't.
766 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
770 Scan for ZOOM API. New object ZOOM_scanset. New functions
771 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
772 ZOOM_scanset_destroy.
774 New ZOOM function, ZOOM_connection_last_event, that returns type
775 of last event (such as "receive data", "send data", "apdu received",
778 New ZOOM option, schema, that specifies schema for retrieval.
780 New CCL feature. Qualifiers can be aliases for one or more
781 other qualifiers (if more than one is given, OR is used).
783 ZOOM uses named result sets if target supports it.
785 Two new YAZ client commands: . (dot, which sources a script of YAZ
786 client commands), and ! (to execute shell command.). Implemented
789 Working on Debian packages.
793 YAZ client enables named result sets only if target supports it.
795 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
797 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
798 with key="host" to get same result.
800 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
801 Function Z3950_resultset_record(s) returns references to records
802 "owned" by resultset. To become owner use Z3950_record_clone.
804 Function z_ext_record handles Extended Services. Thanks to
809 CCL Parser fix: ignore token comma when dealing with and-lists.
811 Documentation updates for COMSTACK.
813 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
814 Changed prototype Z3950_records. For some functions, int parameters
815 were changed to size_t.
817 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
820 New MARC decode/display function, marc_display_exl, which properly rejects
821 non-ISO2709 records. YAZ client uses it.
825 Fix bug: local attribute set wasn't set correctly in PQF strings.
829 * Old Z39.50 codecs no longer supported.
831 Added ZOOM C binding. See http://zoom.z3950.org/
833 Renamed states for COMSTACKs to avoid confusion with events.
835 Implemented cs_look and proper cs_rcvconnect.
837 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
839 Configure detects POSIX threads on OpenBSD.
841 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
842 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
844 When error is returned from present handler, non-surrogate diagnostic
845 is returned in present response (and fetch handler is no longer called).
847 * Minor adjustments to pquery parser (PQF). Token characters may be
848 escaped by using backslash (C-style).
850 PQF parser allows string attribute values to be specified. For @attr,
851 non-numeric characters after the equal-sign are treated as strings
852 (e.g. @attr 9=title).
854 CCL trunction character may be defined (@truncation in file)
856 * function zget_ExtendedServicesRequest sets waitAction to
857 waitIfPossible (was wait).
859 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
862 CCL operator names may be set in field definition files (CCL_bibset).
863 See ccl/bib1 for an example.
865 Fixes in ASN.1 compiler for C++ compatibility.
867 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
868 and "op_or" to avoid conflict with C++.
870 Fixed problem with GNU readline detection on Redhat 7.0.
872 Added step-size for Scan backend handler.
874 Fixed bug that made the frontend server crash when no attribute
875 set was specified for scan.
877 Front-end server automatically switches to original working directory
878 when installed as an NT service. Previously -w had to be specified to
881 Added extended attributes for retrieval module (data1), so that data1
882 records carry d1_readXML/SGML attributes. d1_read also supports
883 null-data rules ( <tag/>)
885 On UNIX when POSIX threads are available, a separate library libyazthread
886 is created. Programmers should link with that library and the yaz library
887 when using threads. The reason for the split was that some applications
888 on Linux, such as Apache, doesn't work well when using shared objects that
891 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
892 (or any frontend server) in SSL mode by specifying ssl: followed by
893 address. Only tested on UNIX.
895 Added feature for CCL module. Virtual structure s=al or s=ol generates
896 and-list and or-list respectively instead of phrase search.
900 * Added prefix "yaz_" for the functions log_init.., log_file.. and
901 log_mask_str. This was done to avoid name conflicts with other libraries
902 (such as other PHP extensions).
904 Added raw OID member for preferred record syntax (request_format_raw)
905 and returned record syntax (output_format_raw) for backend fetch method.
907 Config file yaz-config now accepts options so that it returns specific
908 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
910 Shared library support for UNIX using GNU libtool.
912 * Modified backend interface. Request/Response struct's replaced by
913 one read/write C struct. For example bend_fetchrequest and
914 bend_fetchresult have been replaced by single bend_fetch_rr struct.
915 Every handler - even search has to be registered in bend_init
916 handler. This means that the YAZ library no longer refers to
917 external functions and it makes it possible to make the whole
918 thing a single DLL/SO.
920 Added Segment handler for backend server.
922 Added Zmbol/Zebra administrative functions to YAZ client.
924 Threaded frontend server on UNIX (when POSIX Threads are available).
925 Starting the server with option -T enables multi-threading.
929 Added configure option --enable-comp/disable-comp to control use
930 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
931 located in sub directory asn.
933 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
934 in ${exec_prefix}/bin along with the other programs yaz-client and
937 GNU automake used to maintain makefiles.
941 Changed retrieval module so that we can load records with no abstract
942 syntax defined. Tagpaths in these records are fully composed of string
945 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
949 On UNIX, the generated makefile now supports a proper 'make install'.
950 The prefix can be set via GNU configure to set the install location
951 (default is /usr/local).
953 * YAZ programs client and ztest were renamed to yaz-client and
954 yaz-ztest to avoid conflicts when users install YAZ in "standard"
955 locations, such as /usr/bin,/usr/local/bin,etc.
957 * YAZ Header files were moved from include to include/yaz. YAZ Header
958 files are referred to as include <yaz/log.h> rather than <log.h>.
959 The YAZ include path (-I ..) is therefore the same as before. Programmers
960 should update their #include statements or use -Ipath/include/yaz
961 instead. The main motivation for doing this change is that YAZ header files
962 can be installed in "standard" locations /usr/include,/usr/local/include
963 without introducing conflicts, since ALL YAZ header files are stored
964 in subdirectory yaz (under /usr/include for example).
966 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
967 rather than project/workspace files. We switched because project files
968 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
971 Changed name of logging function, logf, to yaz_log, to prevent name
972 clash with some math-log functions. The YAZ header log.h defines logf
973 to yaz_log (#define) so there should be no incompatibilities by this
976 Added bend_start/bend_stop handlers for server. These handler are
977 called on start/stop of server. For windows they are called whenever
978 a service is started/stopped.
980 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
981 a fairly small ASN.1 compiler written in Tcl. The compiler is located
982 in util/yc.tcl. The auto-generated C code structures are, in a few
983 cases, incompatible with the old decoders. There are differences in the
984 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
985 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
986 The preprocessor variable ASN_COMPILED is defined when the compiled
987 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
988 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
989 wish to use the old encoders/decoders you can specify --disable-yc
992 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
993 version so that it supports both new - and old version of DB Update
995 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
996 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
997 change. The name parameter can be set to 0 in which no name is specified
998 for the construction. The macros odr_implicit and odr_explicit sets name
999 parameter to zero for the construction involved. New macros
1000 odr_implicit_tag and odr_explicit_tag are similar to the others,
1001 except that a name parameter is added. For programmers' that don't use
1002 ODR they probably only need to change the call to z_APDU and z_External.
1004 Added access control facility by interfacing the TCP wrapper library.
1005 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1006 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1007 name of the daemon and enables the access control as specified in
1008 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1010 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1011 den Dool <H.M.vdnDool@kub.nl>.
1013 Added reference ID parameter to most functions in server API - refer
1014 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1016 Changed name of ccl library to libccl.a (was ccl.a).
1018 Fixed bug in decoder for Explain (Category TargetInfo).
1020 Added support for GNU readline in client. Thanks to Jacob Poulsen
1021 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1023 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1024 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1025 IMPLEMENTATION! This change was made to the development version before
1026 the ZIG decided to retract the amendment. If any users MUST be
1027 compatible with the original Update definition, PLEASE CONTACT US, and
1028 we will include a separate definition corresponding to the old Update
1029 ES. Note that because of the change to the ASN.1 of the
1030 TaskPackageRecordStructure we cannot define a single structure that
1031 will support both versions.
1033 * Added const modifier to buffer parameter for some ODR/BER encoding
1034 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1035 completeWAIS, odr_dumpBER.
1037 Fixed bug in client.c which caused a crash when a scanResponse didn't
1038 contain positionOfTerm.
1040 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1041 * will cause an error in a client if a non-YAZ target sends both a
1042 * list of Scan entries and non-surrogate diagnostics.
1044 Retrieval module enhancements. Tag sets may be typed in the reference
1045 to it. From the .abs-file the "tagset" directive takes a third optional
1046 integer type for the tag set referenced. From a .tag-file the "include"
1047 directive takes a third optional type as well. The old "type" directive
1048 in the tag set itself is still recognized but acts as the default type
1051 Backend interface change. Individual Scan terms returned from bend_scan
1052 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1053 in include/backend.h.
1055 Retrieval module enhancements. Multiple tag sets and attribute sets may
1056 be specified in abstract syntax specs. Revised the error/warning for
1057 logging messages reported by the retrieval module when reading the
1060 Object Identifier system (oid_..) changed. The API is backwards
1061 compatible but the oid-routines now allocates new OID's when needed.
1062 Raw OID's may be specified in oid_getvalbyname.
1064 YAZ now uses GNU configure to generate Makefile(s).
1066 * Minor changes in some of the member names of DeleteResultSetRequest and
1067 DeleteResultSetResponse. See include/proto.h.
1069 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1070 and added member 'languages' in TargetInfo (which was missing).
1072 Changed the way attribute sets are handled in the retrieval
1073 module. These are now cached, just like the abstract syntaxes
1076 Changed YAZ so that it links with compiled ASN.1.
1078 Added Explain-schema definitions and mapping routines. The following
1079 Explain categories have been implemented: AttributeDetails,
1080 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1082 Fixed minor bug in Windows version of Server Library.
1084 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1086 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1088 Added EXTERNAL: UNIverse Resource Report (non-standard).
1090 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1091 ENUMERATED and SET OF.
1093 * Added 'const' to some of the char pointer arguments for the
1094 functions, data1_read_node, data1_getelementbytagname,
1095 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1098 Fixed bug in data1_insert_taggeddata - the last_child member of
1099 parent wasn't initialised.
1101 * Changed data1_read_record and data1_read_node so that the supplied
1102 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1103 doesn't refer to any parts of the "SGML"-buffer.
1105 Fixed bug in server library (Windows version of statserv_remove).
1107 * Changed code so that it compiles as C++. The type definition
1108 of Odr_fun which is a member of Odr_arm was changed. The result is,
1109 that an explicit typecast is needed for the fun pointer when
1110 using Odr_arm - as in:
1111 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1113 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1115 Implemented the new structured date and time definition as approved
1116 by the ZIG. Added schemaId element to the specificTag in Espec-1
1117 (also approved at the last ZIG). Thanks to RVDM.
1119 Added some Object identifiers (RVDM).
1121 Changed the Update Extended Service (RVDM).
1123 Added command "refid" to client which specifies referenceId for
1124 the following requests.
1126 Implemented extended service handling for server. See ztest.c
1127 for an example as well as backend.h. New handlers are registerd
1128 in the Init handler.
1130 * Changed interface for sort in server.
1132 Added new members to statserv_options_block. It allows a server
1133 to read options from another source than just the command line. Thanks
1134 to Charles Woodfield.
1136 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1137 renamed to zboolean. Some C++ compilers complained about the name.
1139 Minor changes to gils.abs. Added index 's' (sort) on title
1140 and date/time-last-modified.
1142 --- 1.4pl2 1998/1/30
1144 Fixed bug in server library regarding inetd mode (-i). This bug
1145 was introduced by release 1.4.
1147 --- 1.4pl1 1998/1/29
1149 Added sort facility in client and backend server interface.
1151 Fixed problem with dependencies in Makefile(s).
1153 Fixed bugs for encoders/decoders of extended services and
1156 Implemented sub-tree feature for schemas. Sub-trees are
1157 referenced in *.abs-files. See explain.abs for an example
1158 of the use of this feature.
1160 Modified bib1.att; local attributes for ANY didn't include
1161 ANY itself (only affects use of the retrieval module).
1163 Fixed bug in plain SGML reader in function data1_read_node:
1164 tags with prefix "var" was incorrectly interpreted as variants.
1166 Added feature "sub-schemas" to enable references to - and definitions
1167 of - group of elements.
1169 * Removed member parent from type data1_element (in data1.h).
1171 Implemented function odr_nullval() that returns the value of
1174 * Removed member num_children from data1_node (in data1.h).
1176 Made NT service interface part of the server library. The
1177 function statserv_main uses the NT service when required and
1178 calls the statserv_start / statserv_close routines.
1180 Routine zget_SearchRequest and zget_PresentRequest fills
1181 resultSetName/Id member with "default" instead of "Default".
1183 Fixed memory leak in server. Request queue member wasn't freed.
1185 Fixed nmem_exit so that memory is freed.
1189 Revised the CCL parser utility to be thread safe.
1191 Added function, oid_ent_to_oid, to replace the function
1192 oid_getoidbyent, which is not thread safe.
1194 * Added nmem_init and nmem_exit to initialize and release
1195 NMEM resources. Function nmem_init should be called once in the
1196 initial thread before NMEM/ODR is used. statserv.c and client.c
1197 have been changed accordingly. The change was necessary to make
1198 NMEM thread safe. The NMEM memory pool is shared amongst threads
1199 in a process. Unix-based applications will still work fine without
1202 Added NT Services interface for the the Z39.50 (statserv) Server.
1203 Refer to the ztest.c source on the usage.
1205 Windows 95/NT port using MSVC5.0. Project files are included in the
1208 * Defined new 'global' handle for the retrieval (data1) system. The
1209 new handled, data1_handle, describes the state of the data1 system.
1210 This handle is passed as first argument to virtually all
1211 data1 related routines. The functions data1_create and data1_destroy
1212 creates and destroys a data1 handle respectively.
1214 Added ODR encode stream member to all backend request structures
1215 init, search, scan etc. This stream should be used to allocate all
1216 memory used for the response when thread safe operation is needed.
1218 Changed the comstack utility, cs_addstr, to be thread safe. The
1219 returned hostname string returned by the function is now part the
1222 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1223 function. The cs_straddr takes a COMSTACK handle as argument, so this
1224 function must be used after cs_create and before bind/connect.
1225 This function is thread safe.
1227 Moved test server to 'ztest' directory - generic server code still
1228 in 'server' directory.
1230 Made prefix query (pquery.c) utility thread safe.
1232 Added new function modifier YAZ_EXPORT to 'export' public DLL
1233 functions when using windows (see include/yconfig.h).
1235 Added definitions to the OID database (util/oid.c) (RVDM).
1237 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1239 Added call to ccl_rpn_delete in client program.
1241 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1242 release of RPN structure.
1244 Added support for C++, headers uses extern "C" for public definitions.
1245 With input from RVDM.
1247 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1248 Thanks to Ronald van der Meer (RVDM).
1250 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1252 Added support for private extensions to the OID database
1253 (oid_setprivateoids()). Thanks to RVDM.
1255 Added optional, physical ANY (key replication)
1257 Fixed null-reference problem in GRS-1 output filter.
1259 Proximity operator added to Prefix Query Format (PQF).
1261 In test client command "base" accepts multiple databases.
1263 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1267 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1269 Smallish bug-fixes in the new encoders/decoders (explain).
1271 Bug fixed in DeleteRequest.
1273 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1275 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1277 Added SOIF syntax (using private OID for now) to retrieval module and client.
1279 Added Update extended service.
1281 Added SearchResult-1 additional info structure.
1283 Added optional CCL (ISO8777) interpreter as separate module. Available
1286 --- 1.2 1996/6/10 (1st anniversary release)
1288 Added Summary record syntax. Lightly tested.
1290 Added OPAC record syntax. Untested.
1292 Added ResourceReport service encoders/decoders. Untested.
1294 Fixed bug in z_Unit - wrong tagging on unitSystem.
1296 Fixed bug in the DiagRecs decoder.
1298 Added options for max PDU size and session timeout to frontend-server.
1300 Added documentation of query-language parsers and other supporting utilities.
1302 [frontend-server] Added Attribute set to the bend_scanrequest API.
1304 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1305 surrogate diagnostics were generated.
1307 [retrieval] Allow multiple local values for attribute.
1309 [retrieval] Allow multiple attributes per element in .abs files. index type.
1311 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1313 --- 1.1pl2 1996/4/10
1315 Minor changes, mostly specific to Zebra's requirements (retrieval)
1319 Repaired bug in frontend server when running multiple listening
1320 endpoints in dynamic mode.
1322 z_External() now won't break if a known, ASN.1 value comes encapsulated
1323 in an octet-string. The value will pass through unmodified in an Odr_oct.
1325 Added a bit of code to the demo client to decode & display
1326 ASN.1-structured records represented in the octet-aligned branch of
1327 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1329 Added z_ext_getentbyref() to the ASN module. Doc updated.
1331 * Completed the SCAN definition in the ASN module. This may break SCAN
1332 code based on older YAZ-versions at compile-time. The fix is easy -
1335 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1336 under the SCAN definition. Remember to initialize this, server-people.
1338 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1339 that this does not extend to ODR and ASN.
1341 Comstack allows insertion of established socket (primarily for
1342 inetd-operation of servers). Doc updated.
1344 Front-end server can now start from the inetd in TCP mode. Doc
1347 --- 1.0pl4 1996/1/24
1351 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1352 the rank and record number.
1354 Adjustments to the frontend server.
1356 Fixed diagnostic BER dumper. It ignored the file argument.
1360 Various changes to retrieval module.
1362 Changed the union discriminators of the protocol files from enums to
1363 ints paired with #defines.
1365 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1368 *Changed operator in the RPN structure to 'roperator', again to avoid a
1371 Fixed problems in Explain decoders/encoders.
1373 --- 1.0pl2 1995/12/6
1375 Memory bug in log module fixed.
1377 --- 1.0pl1 1995/12/5
1379 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1381 Bug in Explain DatabaseInfo module fixed.
1383 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1387 The shift to v1.0 signals that we now consider the *core* functionality
1388 of YAZ reasonably stable (the core being more or less equivalent to
1389 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1390 tested (Explain not at all - though that will happen soonish).
1392 Minor changes to code to support Windows port.
1394 Various minor changes after we're getting to use GRS-1 & co. more.
1396 Added Espec-1 format.
1398 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1399 of the protocol and it cannot be selected when encoding (maps into 'string'
1400 when decoding). Needed to talk to some servers.
1402 Demo client can request simple element set names.
1404 Added Diagnostic Format encoders/decoders.
1406 Added simple Close handling to frontend server (no hooks for resource
1407 reporting yet), and demonstration client.
1409 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1411 --- 1.0b3 1995/08/24
1413 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1414 handled incorrectly when records were requested in the searchResponse. This
1415 will only affect you if you use the frontend-server.
1417 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1418 Test-client will ask for and print GRS1. Ztest will return dummy records
1421 Added Explain encoders/decoders to the service-level API. Untested.
1423 Added Extended Services: Item Order encoders and decoders to the Service-
1424 level API. Untested. We could use a recent copy of the pertinent bits
1425 of the ILL protocol to add those bits.
1427 Added diagnostic format 1 encoders/decoders to the service-level API.
1430 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1431 odr_cons.c, which causes a more correct output.
1433 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1434 was always set to 0 when no records were requested in the searchRequest.
1436 * Added better external-handling. This shouldn't harm old code that
1437 *encodes* externals. It can break code that looks for a
1438 'single-ASN1-type' representation, since those types that are known
1439 are now decoded immediately. Look at the SUTRS sample code in
1440 seshigh.c and client.c. Documentation updated.
1442 Handling of structured records in bend_fetchresponse. Length -1 marks
1443 structured record, type is deduced from format field.
1445 --- 1.0b2 1995/06/27
1446 Fairly quick maintenance release to add SUTRS support.
1448 Fixed handling of SUTRS records in the demonstration client.
1450 * Added format field to the bend_fetchrequest and bend_fetchresponce
1451 structures of the backend API (frontend server). When the record is
1452 returned, the value of the format field is mapped to an OID. The
1453 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1454 of the record. The special value VAL_NONE in the bend_request means
1455 that no specific format was requested by the client. Documentation
1456 updated accordingly. Test server (ztest) will return a fixed dummy
1457 SUTRS record if your client requests SUTRS.
1459 Documentation updated accordingly.
1461 You can now set external libraries and RANLIB support in the top-level
1465 First public release.
