1 Possible compatibility problems with earlier versions marked with '*'.
5 Fixed bug #148: CQL parser may leak.
7 * A few prototypes were changed in include/yaz/cql.h.
9 Fixed bug #176: Dont throw diagnostics on empty SRU args.
11 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
13 Fixed bug #172: RPM builds does not enable SSL.
15 Doxyfile.in part of dist. Doxyfile generated by configure.
17 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
18 are given and the corresponding component does not exist.
20 Extend CCL documentation in YAZ reference. Describe r=r.
24 Fixed MARC->MARCXML conversion to properly deal with
25 fields, subfields, indicators having non-ASCII characters.
27 Fixed MARC->MARCXML conversion so that ASCII control characters
28 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
31 Added YAZ GFS support for conversion from Z39.50 surrogate
32 diagnostics to SRW surrogate diagnostics.
34 Bug fix: YAZ GFS did not return schema in explainResponse.
38 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
39 now converts recordSchema to elementSetName as well as schema URI.
41 Fixed bug in COMSTACK that prevented HTTP request packages from being
46 Added CCL facility r=r "range" which is similar to r=o "ordered" but
47 does not require white-space before and after the dash in a range, e.g.
48 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
51 Fixed a few AC_TRY_LINK configure tests that did not operate properly
52 due to new GCC removing "redundant" code.
54 Added yaz-client commands scanpos and scanstep that sets preferred
55 position and step-size for scan.
57 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
59 Added CCL utility ccl_qual_buf which parses one or more CCL
60 spec lines in a buffer.
62 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
63 of name and value - ignoring empty lines and comments.
65 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
67 Added odr_get_element_path which returns current element path for an
68 ODR handle. This utility is useful in error handling or user-defined
71 Added ODR_PRINT utility odr_set_stream which is is a more generic
72 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
73 to a write function and pointer to close function. The close function - if
74 non-NULL - will be called during odr_destroy.
76 Fixed bug in CCL parser where truncation char was not removed from
77 right side when truncation=both was in effect.
79 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
84 Fix buffer overrun in CQL parser when dealing with proximity (%).
86 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
87 to UTF-8/UCS conversion is now only based on codetables.xml.
89 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
93 Add support for more "commit changes" in ZOOM (uses Extended Services).
95 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
98 Yet another small fix for configure of SSL.
100 --- 2.0.21 2004/05/14
102 Fix SSL libs for configure when --with-openssl=DIR is given.
104 --- 2.0.20 2004/05/10
106 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
108 SSL comstack now uses yaz.pem certificate file on server side
109 by default. Certificate filename can be configured by calling
110 comstack function cs_set_ssl_certificate_file before cs_bind is used.
112 Fix bug regarding multiple calls to ZOOM_connection_connect.
114 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
116 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
117 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
119 ZOOM now allows inspection of X509 peer certificate for verification.
120 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
122 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
123 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
124 as "modular" but it simplifies things.
126 Added cs_get_peer_certificate to that returns peer X509 PEM.
128 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
129 NULL if SSL is unavailable.
131 Documentation about MARC decoding tools.
133 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
135 --- 2.0.19 2004/03/30
137 Rename CHANGELOG to NEWS to follow GNU style packing.
139 Fix bug with missing initialization of member in init_diagnostics.
140 This bug affects threaded version of GFS server.
142 --- 2.0.18 2004/03/20
144 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
147 Ensure zlib.dll is packed with Windows install.
149 --- 2.0.17 2004/03/17
151 Fix encoding of xsd:string to use text instead of CDATA.
153 Fix endless loop in CQL parser with unbalanced ".
155 Use a more compact way to store MARC-8 conversion tables.
157 --- 2.0.16 2004/03/16 Debian only
159 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
162 Update CQL parser to use new CQL 1.1 modifiers for booleans and
167 --- 2.0.15 2004/03/01
169 Another fix for decoding of XML packed records.
171 --- 2.0.14 2004/02/25
173 Fixes for Chunked encoding. White space not ignored after length spec.
175 Update NS and use default NS for SRW diagnostic elements.
177 --- 2.0.13 2004/02/23
179 Implement ZOOM_resultset_cache_reset which resets record cache.
181 Implement ZOOM_resultset_sort which sorts a result set.
183 Implement chunked HTTP transfer.
185 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
187 --- 2.0.12 2004/02/16
189 Added member 'schema' to bend_explain_rr structure so that backend
190 can specify explain record identifier. Defaults to Zeerex 2.0.
192 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
194 --- 2.0.11 2004/02/16
196 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
199 Added init command for yaz-client which sends "extra" init request.
201 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
202 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
204 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
206 Make ZOOM error code for "invalid query".
208 Fixed compilation for SSL which wasn't properly enabled for all platforms.
210 --- 2.0.10 2004/02/05
212 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
215 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
217 Added option -p <file> to make Generic Frontend Server to write PID file.
219 Added option -D to put Generic Frontend Server in background on its own.
221 Make ZOOM C recognize option "password". If unset, "pass" is used
222 (for backwards compatibility).
224 Fixed a bug in Generic Frontend Server that could make it crash if a
225 client sets characterSetNegotation bit, but didn't pass negotiation stuff
228 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
229 Must be issued before open, in order to be in effect.
231 --- 2.0.9-6 2004/01/12 Debian/Windows
233 Make the SRU server more picky WRT unknown params, etc.
235 Bug fix: ZOOM scan response didn't return displayTerm - when present.
237 New YAZ client command, options, that sets Z39.50 options.
239 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
240 options from a string of tokens (one token for each option bit).
242 Update SRW diagnostic code messages.
244 --- 2.0.9-5 2004/01/07 Debian/Windows
246 Handle user defined stylesheet for SRW/SRU.
248 --- 2.0.9-4 2004/01/06 Debian/Windows
250 Fix bug in decoding of Content-Length.
252 --- 2.0.9-3 2004/01/06 Debian/Windows
254 Fix a bug with decoding of XML packed records.
256 --- 2.0.9-2 2004/01/05 Debian only
258 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
260 Fix bug in SRW/SRU diagnostics decoding.
264 Fixed bug in Generic Frontend Server which could drop records exceeding
265 preferred message size. Reported and fixed by Irina Dijour.
267 Fixed calculation of package size for structured records in Generic
268 Frontend Server. Reported and fixed by Irina Dijour.
270 Fixed namespace for SRW/SRU diagnostics.
272 Fixed SEGV in yaz-client that occured for HTTP connection errors.
276 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
277 this version is incompatible with version 1.0 and older YAZ SRW/SRU
280 CQL changes to reflect recent changes to the specification:
281 * Documentation talks about context sets instead of index sets.
282 * Documentation talks about indexes instead of qualifiers.
283 * The CQL-to-PQF transformer's configuration file now uses
284 "index.set.name = <attributes>" instead of the old form
285 "qualifier.set.name = <attributes>". (Both forms are still
286 understood but the latter is deprecated.)
287 * CQL terms with no explicit index specified are now interpreted as
288 cql.serverChoice instead of srw.serverChoice (which of course
289 behaves exactly the same.)
293 MARC conversion can now generate ISO2709 output in another
294 character set. yaz-marcdump uses this facility if you invoke it
297 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
298 functions from there can be used from C++.
302 Frontend server now transfers memory from decoded packages to stream
305 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
306 references to show up.
308 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
309 the ZOOM Abstract API. The older names for the same options are still
310 also supported for the benefit of old applications.
312 ZOOM-C supports "implementationId" and "implementationVersion" options
313 to go along with "implementationName". These allow the user code to
314 specify identification strings to be sent to servers.
315 Add OID for the new ExtLite attribute set.
317 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
318 as requested/supplid by Ere Maijala <ere@atp.fi>
320 For generic frontend server, reverse the order of
321 "toolkit-supplied / application-supplied" strings sent as implementationId,
322 Name and Version. Also, remove the spaces around the slash. This brings
323 the GFS in line with the behaviour of ZOOM-C on the client side.
325 Add function ZOOM_scanset_display_term.
327 yaz-client shows scan displayTerm if present.
329 Utility yaz-iconv is now installed by default along with the man page
332 Extend configure check for OpenSSL to use pkg-config where available (such
335 Incorporate patch by Morten Bogeskov which allows a Unix file socket
336 server to specify uid/gid/mask for socket using the format
337 unix:[user=uid,][group=gid,][umask=mask,]file=path
338 If file= is omitted the existing format is assumed, e.g.
340 in which case the mask is 0666 (rw for everybody).
342 Major restructure of YAZ source. All source in libyaz is in src directory.
343 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
344 util (utility programs such as ASN.1 compiler, yaz-marcdump).
346 Added man page for utility yaz-marcdump (used to be called marcdump).
347 yaz-marcdump is installed by 'make install'.
349 Fixed a memory leak in Generic Frontend Server that occurred when decoding
350 of incoming package failed.
352 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
354 Change prototype of odr_perror: add const to message string.
356 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
358 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
359 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
360 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
361 DNS lookup. There should not be any compatibility problems with this
362 assuming that blocking=1 or 0 is used.
364 Fix bad reference in UNIX comstack in function cs_addrstr.
366 Fix for compilation on AIX.
368 The generic front-end server (server/seshigh.c) now supports returning
369 Init diagnostics to the client in User-information-field, in
370 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
375 Allow any CQL relation (not just all,any,exact,scr).
377 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
378 that features the same UI.
380 Implemented command update0 in YAZ client which is equivalent to
381 update but uses old of Ext Update ASN.1.
383 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
384 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
385 Previously no OID was used for this info.
387 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
388 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
389 returns 'malformed search term' otherwise.
391 SortResponse member resultCount now set to NULL in sort handler of
394 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
397 Add three new utility functions for translating OIDs between various
398 formats -- symbolic name such as "Usmarc", minus-1-terminated int
399 arrays and dotted strings such as "1.2.840.10003.9.5.1":
400 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
401 char *oid_to_dotstring(const int *oid, char *oidbuf);
402 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
404 Reverted modifications for ES Update definition for z_IU0Update
405 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
406 is back to YAZ 2.0.2.
408 String value attributes for CCL parser.
410 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
411 which their FirstSearch server returns in Init responses, sometimes
412 carrying useful diagnostic information when Init fails. This has the
413 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
414 "z39.50/oclcui.asn", where its definition is somewhat different from
415 what OCLC document on their web-site, as required to interoperate with
418 Support for anonymous authentication in yaz-client. Use the command
421 * Fix the OID of the Index Data-local "admin" Extended Service from
422 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
423 the 1000, which indicates a locally-defined OID, was a mistake.
427 Fix CCL directive @case handling so that it affects string match for
428 both CCL keywords and qualifiers.
430 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
431 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
432 Decoder has been updated with ASN.1 changes as listed in
433 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
434 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
435 z_IUUpdate, remains unchanged.
437 ZOOM_record_get may now return a record in a specific character set.
438 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
439 "from" is the character set of record as returned by target. "to" is
440 the character set to be returned. If omitted, "to" is UTF-8.
442 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
444 New ODR utility, odr_getelement, which returns name of element for
445 which encoding/decoding failed.
447 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
448 in cases where a required element was omitted.
450 Bug fix: some MARC8 sequences were not converted.
452 New ZOOM option "step" which specifies number of records to be
453 retrieved in one chunk. Used in conjunction with "start" and "count".
455 SRW support for yaz-client. Use scheme http: to use it, e.g.
458 yaz-client no longer does (un)intelligent character set conversions
459 by default. Can be enabled with charset and marc_charset commands.
461 xmalloc trace fix for 64-bit systems such as DEC alpha.
463 Solaris 2.6 compile fix.
465 New function, cql_strerror() translates SRW error codes, as returned
466 by cql_transform_error(), into human-readable English strings. Used
467 in yaz-client diagnostics when appropriate.
469 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
470 converts it into a type-1 query which is sent to the server. This
471 makes CQL available for use with all Z-servers, as opposed to the tiny
472 minority that can handle CQL queries themselves.
476 New Debian package layout similar to the Redhat Package layout.
478 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
479 and search result respectively.
483 Redhat package is now several packages: libyaz (runtime libraries),
484 libyaz-devel (development and documentation, and yaz (utility programs).
485 Package spec file by Morten Bøgeskov.
487 New member 'schema' in struct bend_fetch_rr which the name of requested
488 schema (SRW/SRU) for record (or NULL if none was given). The fetch
489 handler MAY set this to reflect the schema of the returned record.
491 New member 'display_term' in struct scan_entry. GFS now sets member entries
492 and allocates scan entries to be filled by user scan handler. In previous
493 version, entries member was allocated by the scan handler. That still works,
494 but the GFS will ignore member display_term - assuming it was NOT set by
495 the handler. The fact that the GFS now allocates the entries both allows
496 for new members and makes a scan handler easier to write.
498 Fix CQL lex buffer overflow.
500 SRW/SRU recordPacking. For SRW default recordPacking is string. For
501 SRU default recordPacking is string.
503 SRU protocol support for frontend server.
505 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
507 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
509 Added scan for the ZOOM shell (zoomsh).
513 * String Identifers for Schemas (Amendment 5).
514 http://lcweb.loc.gov/z3950/agency/amend/am5.html
515 Old definition for schema
516 Odr_oid *schema; /* OPT */
521 Z_InternationalString *uri;
522 #define Z_Schema_oid 1
523 #define Z_Schema_uri 2
526 * resultCount parameter to Sort Response (Amendment 1).
527 http://lcweb.loc.gov/z3950/agency/amend/am1.html
529 Support for SRW 1.0 over HTTP. This is an optional feature and
530 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
533 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
534 on the same port. SRW SearchRetrieveRequests are mapped
535 to bend_init,bend_search,bend_fetch,bend_close.
537 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
539 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
540 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
542 ZOOM connections are SRW based if schem http is used for hostname
543 in connect, e.g. z = ZOOM_connection_new("http://myserver");
544 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
546 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
547 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
548 distance=n, order=true/false, relation=le, prox unit=word. If
549 n is omitted, distance 1 is used.
551 Fixed problem with C compiler include path in wrong order.
553 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
554 on Solaris. Patch from Ko van der Sloot.
556 New MARC decode API. All new functions operate on a yaz_marc_t
557 handle. The most important new functions are: yaz_marc_create,
558 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
559 decode and destroy respectively. Decoder can produce formats
560 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
561 include/yaz/marcdisp.h.
563 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
564 to UTF-8, UCS-32, wchar_t or Latin-1.
566 * Prototypes for yaz_iconv_-functions moved to separate header
567 include/yaz/yaz-iconv.h.
569 Make a few private functions 'static' in unix.c. This prevents
570 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
572 For ZOOM connection, the options targetImplementation{Id,Name,Version}
573 are set when Init Response is received.
575 New function ZOOM_connection_error_x similar to ZOOM_connection_error
576 but returns diagnostic set as well.
578 New function yaz_strerror which is a portable wrapper for
579 strerror/strerror_r/GetLastMessage.
581 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
582 is returned for MARC. If type is "oai", then OAI MARC is returned.
584 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
589 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
591 Fix bad race conditions on SIGTERM and terminate gracefully in
594 Move retrieval (data1) module to Zebra since nobody seems to be
597 Add GRS-1 render for ZOOM using same format as yaz-client.
601 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
603 Fix broken ESpec handling in data1 module.
605 SGML reader parses comments and makes them part of the data1 tree.
607 Added several type casts so that YAZ compiles as C++ code.
609 ZOOM didn't handle PDU encoding failures properly.
611 Added more Bib-1 diagnostics (approved extensions).
613 GNU configure: better check for iconv.
615 More portable use of accept, getpeername. Check for socklen_t. Use
616 int/size_t if socklen_t is not defined.
620 PQF parser rejects bad queries - including those with extra
621 characters in them. PQF parser used to silently ignore that.
622 Cleaner API for PQF added, which allows you to get detailed
623 error information for bad queries (see yaz/pquery.h).
625 Fixed bug in ZOOM_record_get for type "database".
627 Implemented mini iconv library supporting conversions between
628 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
630 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
634 Fixed ZOOM C record cache so that preferredRecordSyntax and
635 elementSetName is used to check for already fetched records.
639 Added three members in bend_initrequest structure to facilitate
640 character set negotiation.
642 Fixed a bug in frontend server that could cause indefinite
643 loops under rare conditions.
645 Revised character set utilities (charneg.h) so that encoding
646 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
648 For PQF, directive @term <type> sets term type for Scan/Search.
649 Here <type> is general, string, numeric, null. The term type
650 is inherited - just like @attr.
652 New call odr_set_charset that sets character set conversion for
653 international-strings on a ODR stream. Prototype is:
654 int odr_set_charset(ODR o, const char *to, const char *from);
655 The InternationalString is still represented as C string in YAZ
656 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
657 won't). On the protocol level, you can use any encoding.
659 Support for UNIX sockets in ZOOM.
661 Solaris recv sometimes returns errno == ENOENT. It is treated as
662 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
664 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
665 both client and server. Code by Morten Bøgeskov.
669 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
670 that they can be used directly from Visual Basic. You must recompile
671 your windows APP if you're using ZOOM.
673 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
674 Commands "lang" and "charset" sets language and character set respectively.
675 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
676 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
678 Attributes from multiple CCL fields may be OR'ed rather than merged
679 using directive "@field or". Fields are still merged by default -
680 equivalent to "@field merge".
682 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
685 Fixed bug in zget for parameter ExtendedServicesResponse.
691 Added PQF feature: '@attr type=value' may be written as '@type=value'.
693 Client displays USR.1:SearchResult-1 (hits per term).
695 Additional Search Info for search in Generic Frontend Server.
697 Fixed CCL parsing of "field=s".
699 WIN32 installer - using the excellent NSIS software from nullsoft.
701 Fixed CCL parsing of "field = - <number>".
703 Added function yaz_marc_decode that decodes MARC for line mode
704 display or XML (similar to that used by JZKit).
706 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
707 Z39.50. But ISO/ILL was, however.
709 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
710 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

717 New YAZ client features: Command completion and new commands:
718 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
719 Code provided by Jacob Poulsen.
721 New call oid_trav, that visits all registered OIDs via callback.
723 Function ZOOM_record_get now returns const char pointer rather than
724 void pointer. It saves a lot of type casts.
726 For YAZ client, command "auth" now allows you to set authentication
727 in IdPass style. It is enabled when three tokens are given - order
728 is user, group and password.
730 Fix memory leaks in MARC record handling for ZOOM.
732 New option for YAZ client, -k <kilobytes> that sets
733 maximum record size. Similar to -k option for generic frontend
734 server and yaz-ztest.
736 More fixes for scan. Non-zero stepSize handled. OID's fixes.
738 Prefix query parser reports "fail" when bad attribute set is given.
740 Fix in MARC decoder. Proximity logging. Fix for attribute set
741 in scan handler for server. Patches by Shigeru Ishida.
743 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
746 Configure option --with-openssl=<dir> now works when a directory is
747 specified. Patch provided by Morten Bøgeskov.
749 New option for YAZ client, -u <auth>, that sets authentication.
751 ZOOM fix: error information was sometimes "missing", since error
752 was cleared/reset too when it shouldn't.
754 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
758 Scan for ZOOM API. New object ZOOM_scanset. New functions
759 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
760 ZOOM_scanset_destroy.
762 New ZOOM function, ZOOM_connection_last_event, that returns type
763 of last event (such as "receive data", "send data", "apdu received",
766 New ZOOM option, schema, that specifies schema for retrieval.
768 New CCL feature. Qualifiers can be aliases for one or more
769 other qualifiers (if more than one is given, OR is used).
771 ZOOM uses named result sets if target supports it.
773 Two new YAZ client commands: . (dot, which sources a script of YAZ
774 client commands), and ! (to execute shell command.). Implemented
777 Working on Debian packages.
781 YAZ client enables named result sets only if target supports it.
783 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
785 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
786 with key="host" to get same result.
788 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
789 Function Z3950_resultset_record(s) returns references to records
790 "owned" by resultset. To become owner use Z3950_record_clone.
792 Function z_ext_record handles Extended Services. Thanks to
797 CCL Parser fix: ignore token comma when dealing with and-lists.
799 Documentation updates for COMSTACK.
801 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
802 Changed prototype Z3950_records. For some functions, int parameters
803 were changed to size_t.
805 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
808 New MARC decode/display function, marc_display_exl, which properly rejects
809 non-ISO2709 records. YAZ client uses it.
813 Fix bug: local attribute set wasn't set correctly in PQF strings.
817 * Old Z39.50 codecs no longer supported.
819 Added ZOOM C binding. See http://zoom.z3950.org/
821 Renamed states for COMSTACKs to avoid confusion with events.
823 Implemented cs_look and proper cs_rcvconnect.
825 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
827 Configure detects POSIX threads on OpenBSD.
829 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
830 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
832 When error is returned from present handler, non-surrogate diagnostic
833 is returned in present response (and fetch handler is no longer called).
835 * Minor adjustments to pquery parser (PQF). Token characters may be
836 escaped by using backslash (C-style).
838 PQF parser allows string attribute values to be specified. For @attr,
839 non-numeric characters after the equal-sign are treated as strings
840 (e.g. @attr 9=title).
842 CCL trunction character may be defined (@truncation in file)
844 * function zget_ExtendedServicesRequest sets waitAction to
845 waitIfPossible (was wait).
847 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
850 CCL operator names may be set in field definition files (CCL_bibset).
851 See ccl/bib1 for an example.
853 Fixes in ASN.1 compiler for C++ compatibility.
855 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
856 and "op_or" to avoid conflict with C++.
858 Fixed problem with GNU readline detection on Redhat 7.0.
860 Added step-size for Scan backend handler.
862 Fixed bug that made the frontend server crash when no attribute
863 set was specified for scan.
865 Front-end server automatically switches to original working directory
866 when installed as an NT service. Previously -w had to be specified to
869 Added extended attributes for retrieval module (data1), so that data1
870 records carry d1_readXML/SGML attributes. d1_read also supports
871 null-data rules ( <tag/>)
873 On UNIX when POSIX threads are available, a separate library libyazthread
874 is created. Programmers should link with that library and the yaz library
875 when using threads. The reason for the split was that some applications
876 on Linux, such as Apache, doesn't work well when using shared objects that
879 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
880 (or any frontend server) in SSL mode by specifying ssl: followed by
881 address. Only tested on UNIX.
883 Added feature for CCL module. Virtual structure s=al or s=ol generates
884 and-list and or-list respectively instead of phrase search.
888 * Added prefix "yaz_" for the functions log_init.., log_file.. and
889 log_mask_str. This was done to avoid name conflicts with other libraries
890 (such as other PHP extensions).
892 Added raw OID member for preferred record syntax (request_format_raw)
893 and returned record syntax (output_format_raw) for backend fetch method.
895 Config file yaz-config now accepts options so that it returns specific
896 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
898 Shared library support for UNIX using GNU libtool.
900 * Modified backend interface. Request/Response struct's replaced by
901 one read/write C struct. For example bend_fetchrequest and
902 bend_fetchresult have been replaced by single bend_fetch_rr struct.
903 Every handler - even search has to be registered in bend_init
904 handler. This means that the YAZ library no longer refers to
905 external functions and it makes it possible to make the whole
906 thing a single DLL/SO.
908 Added Segment handler for backend server.
910 Added Zmbol/Zebra administrative functions to YAZ client.
912 Threaded frontend server on UNIX (when POSIX Threads are available).
913 Starting the server with option -T enables multi-threading.
917 Added configure option --enable-comp/disable-comp to control use
918 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
919 located in sub directory asn.
921 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
922 in ${exec_prefix}/bin along with the other programs yaz-client and
925 GNU automake used to maintain makefiles.
929 Changed retrieval module so that we can load records with no abstract
930 syntax defined. Tagpaths in these records are fully composed of string
933 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
937 On UNIX, the generated makefile now supports a proper 'make install'.
938 The prefix can be set via GNU configure to set the install location
939 (default is /usr/local).
941 * YAZ programs client and ztest were renamed to yaz-client and
942 yaz-ztest to avoid conflicts when users install YAZ in "standard"
943 locations, such as /usr/bin,/usr/local/bin,etc.
945 * YAZ Header files were moved from include to include/yaz. YAZ Header
946 files are referred to as include <yaz/log.h> rather than <log.h>.
947 The YAZ include path (-I ..) is therefore the same as before. Programmers
948 should update their #include statements or use -Ipath/include/yaz
949 instead. The main motivation for doing this change is that YAZ header files
950 can be installed in "standard" locations /usr/include,/usr/local/include
951 without introducing conflicts, since ALL YAZ header files are stored
952 in subdirectory yaz (under /usr/include for example).
954 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
955 rather than project/workspace files. We switched because project files
956 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
959 Changed name of logging function, logf, to yaz_log, to prevent name
960 clash with some math-log functions. The YAZ header log.h defines logf
961 to yaz_log (#define) so there should be no incompatibilities by this
964 Added bend_start/bend_stop handlers for server. These handler are
965 called on start/stop of server. For windows they are called whenever
966 a service is started/stopped.
968 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
969 a fairly small ASN.1 compiler written in Tcl. The compiler is located
970 in util/yc.tcl. The auto-generated C code structures are, in a few
971 cases, incompatible with the old decoders. There are differences in the
972 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
973 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
974 The preprocessor variable ASN_COMPILED is defined when the compiled
975 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
976 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
977 wish to use the old encoders/decoders you can specify --disable-yc
980 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
981 version so that it supports both new - and old version of DB Update
983 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
984 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
985 change. The name parameter can be set to 0 in which no name is specified
986 for the construction. The macros odr_implicit and odr_explicit sets name
987 parameter to zero for the construction involved. New macros
988 odr_implicit_tag and odr_explicit_tag are similar to the others,
989 except that a name parameter is added. For programmers' that don't use
990 ODR they probably only need to change the call to z_APDU and z_External.
992 Added access control facility by interfacing the TCP wrapper library.
993 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
994 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
995 name of the daemon and enables the access control as specified in
996 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
998 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
999 den Dool <H.M.vdnDool@kub.nl>.
1001 Added reference ID parameter to most functions in server API - refer
1002 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1004 Changed name of ccl library to libccl.a (was ccl.a).
1006 Fixed bug in decoder for Explain (Category TargetInfo).
1008 Added support for GNU readline in client. Thanks to Jacob Poulsen
1009 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1011 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1012 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1013 IMPLEMENTATION! This change was made to the development version before
1014 the ZIG decided to retract the amendment. If any users MUST be
1015 compatible with the original Update definition, PLEASE CONTACT US, and
1016 we will include a separate definition corresponding to the old Update
1017 ES. Note that because of the change to the ASN.1 of the
1018 TaskPackageRecordStructure we cannot define a single structure that
1019 will support both versions.
1021 * Added const modifier to buffer parameter for some ODR/BER encoding
1022 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1023 completeWAIS, odr_dumpBER.
1025 Fixed bug in client.c which caused a crash when a scanResponse didn't
1026 contain positionOfTerm.
1028 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1029 * will cause an error in a client if a non-YAZ target sends both a
1030 * list of Scan entries and non-surrogate diagnostics.
1032 Retrieval module enhancements. Tag sets may be typed in the reference
1033 to it. From the .abs-file the "tagset" directive takes a third optional
1034 integer type for the tag set referenced. From a .tag-file the "include"
1035 directive takes a third optional type as well. The old "type" directive
1036 in the tag set itself is still recognized but acts as the default type
1039 Backend interface change. Individual Scan terms returned from bend_scan
1040 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1041 in include/backend.h.
1043 Retrieval module enhancements. Multiple tag sets and attribute sets may
1044 be specified in abstract syntax specs. Revised the error/warning for
1045 logging messages reported by the retrieval module when reading the
1048 Object Identifier system (oid_..) changed. The API is backwards
1049 compatible but the oid-routines now allocates new OID's when needed.
1050 Raw OID's may be specified in oid_getvalbyname.
1052 YAZ now uses GNU configure to generate Makefile(s).
1054 * Minor changes in some of the member names of DeleteResultSetRequest and
1055 DeleteResultSetResponse. See include/proto.h.
1057 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1058 and added member 'languages' in TargetInfo (which was missing).
1060 Changed the way attribute sets are handled in the retrieval
1061 module. These are now cached, just like the abstract syntaxes
1064 Changed YAZ so that it links with compiled ASN.1.
1066 Added Explain-schema definitions and mapping routines. The following
1067 Explain categories have been implemented: AttributeDetails,
1068 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1070 Fixed minor bug in Windows version of Server Library.
1072 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1074 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1076 Added EXTERNAL: UNIverse Resource Report (non-standard).
1078 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1079 ENUMERATED and SET OF.
1081 * Added 'const' to some of the char pointer arguments for the
1082 functions, data1_read_node, data1_getelementbytagname,
1083 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1086 Fixed bug in data1_insert_taggeddata - the last_child member of
1087 parent wasn't initialised.
1089 * Changed data1_read_record and data1_read_node so that the supplied
1090 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1091 doesn't refer to any parts of the "SGML"-buffer.
1093 Fixed bug in server library (Windows version of statserv_remove).
1095 * Changed code so that it compiles as C++. The type definition
1096 of Odr_fun which is a member of Odr_arm was changed. The result is,
1097 that an explicit typecast is needed for the fun pointer when
1098 using Odr_arm - as in:
1099 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1101 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1103 Implemented the new structured date and time definition as approved
1104 by the ZIG. Added schemaId element to the specificTag in Espec-1
1105 (also approved at the last ZIG). Thanks to RVDM.
1107 Added some Object identifiers (RVDM).
1109 Changed the Update Extended Service (RVDM).
1111 Added command "refid" to client which specifies referenceId for
1112 the following requests.
1114 Implemented extended service handling for server. See ztest.c
1115 for an example as well as backend.h. New handlers are registerd
1116 in the Init handler.
1118 * Changed interface for sort in server.
1120 Added new members to statserv_options_block. It allows a server
1121 to read options from another source than just the command line. Thanks
1122 to Charles Woodfield.
1124 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1125 renamed to zboolean. Some C++ compilers complained about the name.
1127 Minor changes to gils.abs. Added index 's' (sort) on title
1128 and date/time-last-modified.
1130 --- 1.4pl2 1998/1/30
1132 Fixed bug in server library regarding inetd mode (-i). This bug
1133 was introduced by release 1.4.
1135 --- 1.4pl1 1998/1/29
1137 Added sort facility in client and backend server interface.
1139 Fixed problem with dependencies in Makefile(s).
1141 Fixed bugs for encoders/decoders of extended services and
1144 Implemented sub-tree feature for schemas. Sub-trees are
1145 referenced in *.abs-files. See explain.abs for an example
1146 of the use of this feature.
1148 Modified bib1.att; local attributes for ANY didn't include
1149 ANY itself (only affects use of the retrieval module).
1151 Fixed bug in plain SGML reader in function data1_read_node:
1152 tags with prefix "var" was incorrectly interpreted as variants.
1154 Added feature "sub-schemas" to enable references to - and definitions
1155 of - group of elements.
1157 * Removed member parent from type data1_element (in data1.h).
1159 Implemented function odr_nullval() that returns the value of
1162 * Removed member num_children from data1_node (in data1.h).
1164 Made NT service interface part of the server library. The
1165 function statserv_main uses the NT service when required and
1166 calls the statserv_start / statserv_close routines.
1168 Routine zget_SearchRequest and zget_PresentRequest fills
1169 resultSetName/Id member with "default" instead of "Default".
1171 Fixed memory leak in server. Request queue member wasn't freed.
1173 Fixed nmem_exit so that memory is freed.
1177 Revised the CCL parser utility to be thread safe.
1179 Added function, oid_ent_to_oid, to replace the function
1180 oid_getoidbyent, which is not thread safe.
1182 * Added nmem_init and nmem_exit to initialize and release
1183 NMEM resources. Function nmem_init should be called once in the
1184 initial thread before NMEM/ODR is used. statserv.c and client.c
1185 have been changed accordingly. The change was necessary to make
1186 NMEM thread safe. The NMEM memory pool is shared amongst threads
1187 in a process. Unix-based applications will still work fine without
1190 Added NT Services interface for the the Z39.50 (statserv) Server.
1191 Refer to the ztest.c source on the usage.
1193 Windows 95/NT port using MSVC5.0. Project files are included in the
1196 * Defined new 'global' handle for the retrieval (data1) system. The
1197 new handled, data1_handle, describes the state of the data1 system.
1198 This handle is passed as first argument to virtually all
1199 data1 related routines. The functions data1_create and data1_destroy
1200 creates and destroys a data1 handle respectively.
1202 Added ODR encode stream member to all backend request structures
1203 init, search, scan etc. This stream should be used to allocate all
1204 memory used for the response when thread safe operation is needed.
1206 Changed the comstack utility, cs_addstr, to be thread safe. The
1207 returned hostname string returned by the function is now part the
1210 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1211 function. The cs_straddr takes a COMSTACK handle as argument, so this
1212 function must be used after cs_create and before bind/connect.
1213 This function is thread safe.
1215 Moved test server to 'ztest' directory - generic server code still
1216 in 'server' directory.
1218 Made prefix query (pquery.c) utility thread safe.
1220 Added new function modifier YAZ_EXPORT to 'export' public DLL
1221 functions when using windows (see include/yconfig.h).
1223 Added definitions to the OID database (util/oid.c) (RVDM).
1225 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1227 Added call to ccl_rpn_delete in client program.
1229 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1230 release of RPN structure.
1232 Added support for C++, headers uses extern "C" for public definitions.
1233 With input from RVDM.
1235 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1236 Thanks to Ronald van der Meer (RVDM).
1238 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1240 Added support for private extensions to the OID database
1241 (oid_setprivateoids()). Thanks to RVDM.
1243 Added optional, physical ANY (key replication)
1245 Fixed null-reference problem in GRS-1 output filter.
1247 Proximity operator added to Prefix Query Format (PQF).
1249 In test client command "base" accepts multiple databases.
1251 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1255 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1257 Smallish bug-fixes in the new encoders/decoders (explain).
1259 Bug fixed in DeleteRequest.
1261 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1263 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1265 Added SOIF syntax (using private OID for now) to retrieval module and client.
1267 Added Update extended service.
1269 Added SearchResult-1 additional info structure.
1271 Added optional CCL (ISO8777) interpreter as separate module. Available
1274 --- 1.2 1996/6/10 (1st anniversary release)
1276 Added Summary record syntax. Lightly tested.
1278 Added OPAC record syntax. Untested.
1280 Added ResourceReport service encoders/decoders. Untested.
1282 Fixed bug in z_Unit - wrong tagging on unitSystem.
1284 Fixed bug in the DiagRecs decoder.
1286 Added options for max PDU size and session timeout to frontend-server.
1288 Added documentation of query-language parsers and other supporting utilities.
1290 [frontend-server] Added Attribute set to the bend_scanrequest API.
1292 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1293 surrogate diagnostics were generated.
1295 [retrieval] Allow multiple local values for attribute.
1297 [retrieval] Allow multiple attributes per element in .abs files. index type.
1299 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1301 --- 1.1pl2 1996/4/10
1303 Minor changes, mostly specific to Zebra's requirements (retrieval)
1307 Repaired bug in frontend server when running multiple listening
1308 endpoints in dynamic mode.
1310 z_External() now won't break if a known, ASN.1 value comes encapsulated
1311 in an octet-string. The value will pass through unmodified in an Odr_oct.
1313 Added a bit of code to the demo client to decode & display
1314 ASN.1-structured records represented in the octet-aligned branch of
1315 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1317 Added z_ext_getentbyref() to the ASN module. Doc updated.
1319 * Completed the SCAN definition in the ASN module. This may break SCAN
1320 code based on older YAZ-versions at compile-time. The fix is easy -
1323 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1324 under the SCAN definition. Remember to initialize this, server-people.
1326 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1327 that this does not extend to ODR and ASN.
1329 Comstack allows insertion of established socket (primarily for
1330 inetd-operation of servers). Doc updated.
1332 Front-end server can now start from the inetd in TCP mode. Doc
1335 --- 1.0pl4 1996/1/24
1339 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1340 the rank and record number.
1342 Adjustments to the frontend server.
1344 Fixed diagnostic BER dumper. It ignored the file argument.
1348 Various changes to retrieval module.
1350 Changed the union discriminators of the protocol files from enums to
1351 ints paired with #defines.
1353 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1356 *Changed operator in the RPN structure to 'roperator', again to avoid a
1359 Fixed problems in Explain decoders/encoders.
1361 --- 1.0pl2 1995/12/6
1363 Memory bug in log module fixed.
1365 --- 1.0pl1 1995/12/5
1367 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1369 Bug in Explain DatabaseInfo module fixed.
1371 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1375 The shift to v1.0 signals that we now consider the *core* functionality
1376 of YAZ reasonably stable (the core being more or less equivalent to
1377 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1378 tested (Explain not at all - though that will happen soonish).
1380 Minor changes to code to support Windows port.
1382 Various minor changes after we're getting to use GRS-1 & co. more.
1384 Added Espec-1 format.
1386 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1387 of the protocol and it cannot be selected when encoding (maps into 'string'
1388 when decoding). Needed to talk to some servers.
1390 Demo client can request simple element set names.
1392 Added Diagnostic Format encoders/decoders.
1394 Added simple Close handling to frontend server (no hooks for resource
1395 reporting yet), and demonstration client.
1397 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1399 --- 1.0b3 1995/08/24
1401 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1402 handled incorrectly when records were requested in the searchResponse. This
1403 will only affect you if you use the frontend-server.
1405 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1406 Test-client will ask for and print GRS1. Ztest will return dummy records
1409 Added Explain encoders/decoders to the service-level API. Untested.
1411 Added Extended Services: Item Order encoders and decoders to the Service-
1412 level API. Untested. We could use a recent copy of the pertinent bits
1413 of the ILL protocol to add those bits.
1415 Added diagnostic format 1 encoders/decoders to the service-level API.
1418 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1419 odr_cons.c, which causes a more correct output.
1421 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1422 was always set to 0 when no records were requested in the searchRequest.
1424 * Added better external-handling. This shouldn't harm old code that
1425 *encodes* externals. It can break code that looks for a
1426 'single-ASN1-type' representation, since those types that are known
1427 are now decoded immediately. Look at the SUTRS sample code in
1428 seshigh.c and client.c. Documentation updated.
1430 Handling of structured records in bend_fetchresponse. Length -1 marks
1431 structured record, type is deduced from format field.
1433 --- 1.0b2 1995/06/27
1434 Fairly quick maintenance release to add SUTRS support.
1436 Fixed handling of SUTRS records in the demonstration client.
1438 * Added format field to the bend_fetchrequest and bend_fetchresponce
1439 structures of the backend API (frontend server). When the record is
1440 returned, the value of the format field is mapped to an OID. The
1441 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1442 of the record. The special value VAL_NONE in the bend_request means
1443 that no specific format was requested by the client. Documentation
1444 updated accordingly. Test server (ztest) will return a fixed dummy
1445 SUTRS record if your client requests SUTRS.
1447 Documentation updated accordingly.
1449 You can now set external libraries and RANLIB support in the top-level
1453 First public release.
