1 Possible compatibility problems with earlier versions marked with '*'.
3 Bug fix: YAZ GFS did not return schema in explainResponse.
7 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
8 now converts recordSchema to elementSetName as well as schema URI.
10 Fixed bug in COMSTACK that prevented HTTP request packages from being
15 Added CCL facility r=r "range" which is similar to r=o "ordered" but
16 does not require white-space before and after the dash in a range, e.g.
17 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
20 Fixed a few AC_TRY_LINK configure tests that did not operate properly
21 due to new GCC removing "redundant" code.
23 Added yaz-client commands scanpos and scanstep that sets preferred
24 position and step-size for scan.
26 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
28 Added CCL utility ccl_qual_buf which parses one or more CCL
29 spec lines in a buffer.
31 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
32 of name and value - ignoring empty lines and comments.
34 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
36 Added odr_get_element_path which returns current element path for an
37 ODR handle. This utility is useful in error handling or user-defined
40 Added ODR_PRINT utility odr_set_stream which is is a more generic
41 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
42 to a write function and pointer to close function. The close function - if
43 non-NULL - will be called during odr_destroy.
45 Fixed bug in CCL parser where truncation char was not removed from
46 right side when truncation=both was in effect.
48 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
53 Fix buffer overrun in CQL parser when dealing with proximity (%).
55 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
56 to UTF-8/UCS conversion is now only based on codetables.xml.
58 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
62 Add support for more "commit changes" in ZOOM (uses Extended Services).
64 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
67 Yet another small fix for configure of SSL.
71 Fix SSL libs for configure when --with-openssl=DIR is given.
75 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
77 SSL comstack now uses yaz.pem certificate file on server side
78 by default. Certificate filename can be configured by calling
79 comstack function cs_set_ssl_certificate_file before cs_bind is used.
81 Fix bug regarding multiple calls to ZOOM_connection_connect.
83 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
85 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
86 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
88 ZOOM now allows inspection of X509 peer certificate for verification.
89 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
91 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
92 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
93 as "modular" but it simplifies things.
95 Added cs_get_peer_certificate to that returns peer X509 PEM.
97 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
98 NULL if SSL is unavailable.
100 Documentation about MARC decoding tools.
102 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
104 --- 2.0.19 2004/03/30
106 Rename CHANGELOG to NEWS to follow GNU style packing.
108 Fix bug with missing initialization of member in init_diagnostics.
109 This bug affects threaded version of GFS server.
111 --- 2.0.18 2004/03/20
113 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
116 Ensure zlib.dll is packed with Windows install.
118 --- 2.0.17 2004/03/17
120 Fix encoding of xsd:string to use text instead of CDATA.
122 Fix endless loop in CQL parser with unbalanced ".
124 Use a more compact way to store MARC-8 conversion tables.
126 --- 2.0.16 2004/03/16 Debian only
128 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
131 Update CQL parser to use new CQL 1.1 modifiers for booleans and
136 --- 2.0.15 2004/03/01
138 Another fix for decoding of XML packed records.
140 --- 2.0.14 2004/02/25
142 Fixes for Chunked encoding. White space not ignored after length spec.
144 Update NS and use default NS for SRW diagnostic elements.
146 --- 2.0.13 2004/02/23
148 Implement ZOOM_resultset_cache_reset which resets record cache.
150 Implement ZOOM_resultset_sort which sorts a result set.
152 Implement chunked HTTP transfer.
154 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
156 --- 2.0.12 2004/02/16
158 Added member 'schema' to bend_explain_rr structure so that backend
159 can specify explain record identifier. Defaults to Zeerex 2.0.
161 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
163 --- 2.0.11 2004/02/16
165 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
168 Added init command for yaz-client which sends "extra" init request.
170 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
171 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
173 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
175 Make ZOOM error code for "invalid query".
177 Fixed compilation for SSL which wasn't properly enabled for all platforms.
179 --- 2.0.10 2004/02/05
181 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
184 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
186 Added option -p <file> to make Generic Frontend Server to write PID file.
188 Added option -D to put Generic Frontend Server in background on its own.
190 Make ZOOM C recognize option "password". If unset, "pass" is used
191 (for backwards compatibility).
193 Fixed a bug in Generic Frontend Server that could make it crash if a
194 client sets characterSetNegotation bit, but didn't pass negotiation stuff
197 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
198 Must be issued before open, in order to be in effect.
200 --- 2.0.9-6 2004/01/12 Debian/Windows
202 Make the SRU server more picky WRT unknown params, etc.
204 Bug fix: ZOOM scan response didn't return displayTerm - when present.
206 New YAZ client command, options, that sets Z39.50 options.
208 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
209 options from a string of tokens (one token for each option bit).
211 Update SRW diagnostic code messages.
213 --- 2.0.9-5 2004/01/07 Debian/Windows
215 Handle user defined stylesheet for SRW/SRU.
217 --- 2.0.9-4 2004/01/06 Debian/Windows
219 Fix bug in decoding of Content-Length.
221 --- 2.0.9-3 2004/01/06 Debian/Windows
223 Fix a bug with decoding of XML packed records.
225 --- 2.0.9-2 2004/01/05 Debian only
227 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
229 Fix bug in SRW/SRU diagnostics decoding.
233 Fixed bug in Generic Frontend Server which could drop records exceeding
234 preferred message size. Reported and fixed by Irina Dijour.
236 Fixed calculation of package size for structured records in Generic
237 Frontend Server. Reported and fixed by Irina Dijour.
239 Fixed namespace for SRW/SRU diagnostics.
241 Fixed SEGV in yaz-client that occured for HTTP connection errors.
245 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
246 this version is incompatible with version 1.0 and older YAZ SRW/SRU
249 CQL changes to reflect recent changes to the specification:
250 * Documentation talks about context sets instead of index sets.
251 * Documentation talks about indexes instead of qualifiers.
252 * The CQL-to-PQF transformer's configuration file now uses
253 "index.set.name = <attributes>" instead of the old form
254 "qualifier.set.name = <attributes>". (Both forms are still
255 understood but the latter is deprecated.)
256 * CQL terms with no explicit index specified are now interpreted as
257 cql.serverChoice instead of srw.serverChoice (which of course
258 behaves exactly the same.)
262 MARC conversion can now generate ISO2709 output in another
263 character set. yaz-marcdump uses this facility if you invoke it
266 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
267 functions from there can be used from C++.
271 Frontend server now transfers memory from decoded packages to stream
274 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
275 references to show up.
277 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
278 the ZOOM Abstract API. The older names for the same options are still
279 also supported for the benefit of old applications.
281 ZOOM-C supports "implementationId" and "implementationVersion" options
282 to go along with "implementationName". These allow the user code to
283 specify identification strings to be sent to servers.
284 Add OID for the new ExtLite attribute set.
286 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
287 as requested/supplid by Ere Maijala <ere@atp.fi>
289 For generic frontend server, reverse the order of
290 "toolkit-supplied / application-supplied" strings sent as implementationId,
291 Name and Version. Also, remove the spaces around the slash. This brings
292 the GFS in line with the behaviour of ZOOM-C on the client side.
294 Add function ZOOM_scanset_display_term.
296 yaz-client shows scan displayTerm if present.
298 Utility yaz-iconv is now installed by default along with the man page
301 Extend configure check for OpenSSL to use pkg-config where available (such
304 Incorporate patch by Morten Bogeskov which allows a Unix file socket
305 server to specify uid/gid/mask for socket using the format
306 unix:[user=uid,][group=gid,][umask=mask,]file=path
307 If file= is omitted the existing format is assumed, e.g.
309 in which case the mask is 0666 (rw for everybody).
311 Major restructure of YAZ source. All source in libyaz is in src directory.
312 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
313 util (utility programs such as ASN.1 compiler, yaz-marcdump).
315 Added man page for utility yaz-marcdump (used to be called marcdump).
316 yaz-marcdump is installed by 'make install'.
318 Fixed a memory leak in Generic Frontend Server that occurred when decoding
319 of incoming package failed.
321 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
323 Change prototype of odr_perror: add const to message string.
325 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
327 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
328 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
329 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
330 DNS lookup. There should not be any compatibility problems with this
331 assuming that blocking=1 or 0 is used.
333 Fix bad reference in UNIX comstack in function cs_addrstr.
335 Fix for compilation on AIX.
337 The generic front-end server (server/seshigh.c) now supports returning
338 Init diagnostics to the client in User-information-field, in
339 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
344 Allow any CQL relation (not just all,any,exact,scr).
346 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
347 that features the same UI.
349 Implemented command update0 in YAZ client which is equivalent to
350 update but uses old of Ext Update ASN.1.
352 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
353 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
354 Previously no OID was used for this info.
356 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
357 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
358 returns 'malformed search term' otherwise.
360 SortResponse member resultCount now set to NULL in sort handler of
363 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
366 Add three new utility functions for translating OIDs between various
367 formats -- symbolic name such as "Usmarc", minus-1-terminated int
368 arrays and dotted strings such as "1.2.840.10003.9.5.1":
369 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
370 char *oid_to_dotstring(const int *oid, char *oidbuf);
371 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
373 Reverted modifications for ES Update definition for z_IU0Update
374 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
375 is back to YAZ 2.0.2.
377 String value attributes for CCL parser.
379 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
380 which their FirstSearch server returns in Init responses, sometimes
381 carrying useful diagnostic information when Init fails. This has the
382 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
383 "z39.50/oclcui.asn", where its definition is somewhat different from
384 what OCLC document on their web-site, as required to interoperate with
387 Support for anonymous authentication in yaz-client. Use the command
390 * Fix the OID of the Index Data-local "admin" Extended Service from
391 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
392 the 1000, which indicates a locally-defined OID, was a mistake.
396 Fix CCL directive @case handling so that it affects string match for
397 both CCL keywords and qualifiers.
399 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
400 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
401 Decoder has been updated with ASN.1 changes as listed in
402 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
403 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
404 z_IUUpdate, remains unchanged.
406 ZOOM_record_get may now return a record in a specific character set.
407 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
408 "from" is the character set of record as returned by target. "to" is
409 the character set to be returned. If omitted, "to" is UTF-8.
411 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
413 New ODR utility, odr_getelement, which returns name of element for
414 which encoding/decoding failed.
416 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
417 in cases where a required element was omitted.
419 Bug fix: some MARC8 sequences were not converted.
421 New ZOOM option "step" which specifies number of records to be
422 retrieved in one chunk. Used in conjunction with "start" and "count".
424 SRW support for yaz-client. Use scheme http: to use it, e.g.
427 yaz-client no longer does (un)intelligent character set conversions
428 by default. Can be enabled with charset and marc_charset commands.
430 xmalloc trace fix for 64-bit systems such as DEC alpha.
432 Solaris 2.6 compile fix.
434 New function, cql_strerror() translates SRW error codes, as returned
435 by cql_transform_error(), into human-readable English strings. Used
436 in yaz-client diagnostics when appropriate.
438 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
439 converts it into a type-1 query which is sent to the server. This
440 makes CQL available for use with all Z-servers, as opposed to the tiny
441 minority that can handle CQL queries themselves.
445 New Debian package layout similar to the Redhat Package layout.
447 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
448 and search result respectively.
452 Redhat package is now several packages: libyaz (runtime libraries),
453 libyaz-devel (development and documentation, and yaz (utility programs).
454 Package spec file by Morten Bøgeskov.
456 New member 'schema' in struct bend_fetch_rr which the name of requested
457 schema (SRW/SRU) for record (or NULL if none was given). The fetch
458 handler MAY set this to reflect the schema of the returned record.
460 New member 'display_term' in struct scan_entry. GFS now sets member entries
461 and allocates scan entries to be filled by user scan handler. In previous
462 version, entries member was allocated by the scan handler. That still works,
463 but the GFS will ignore member display_term - assuming it was NOT set by
464 the handler. The fact that the GFS now allocates the entries both allows
465 for new members and makes a scan handler easier to write.
467 Fix CQL lex buffer overflow.
469 SRW/SRU recordPacking. For SRW default recordPacking is string. For
470 SRU default recordPacking is string.
472 SRU protocol support for frontend server.
474 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
476 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
478 Added scan for the ZOOM shell (zoomsh).
482 * String Identifers for Schemas (Amendment 5).
483 http://lcweb.loc.gov/z3950/agency/amend/am5.html
484 Old definition for schema
485 Odr_oid *schema; /* OPT */
490 Z_InternationalString *uri;
491 #define Z_Schema_oid 1
492 #define Z_Schema_uri 2
495 * resultCount parameter to Sort Response (Amendment 1).
496 http://lcweb.loc.gov/z3950/agency/amend/am1.html
498 Support for SRW 1.0 over HTTP. This is an optional feature and
499 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
502 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
503 on the same port. SRW SearchRetrieveRequests are mapped
504 to bend_init,bend_search,bend_fetch,bend_close.
506 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
508 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
509 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
511 ZOOM connections are SRW based if schem http is used for hostname
512 in connect, e.g. z = ZOOM_connection_new("http://myserver");
513 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
515 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
516 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
517 distance=n, order=true/false, relation=le, prox unit=word. If
518 n is omitted, distance 1 is used.
520 Fixed problem with C compiler include path in wrong order.
522 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
523 on Solaris. Patch from Ko van der Sloot.
525 New MARC decode API. All new functions operate on a yaz_marc_t
526 handle. The most important new functions are: yaz_marc_create,
527 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
528 decode and destroy respectively. Decoder can produce formats
529 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
530 include/yaz/marcdisp.h.
532 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
533 to UTF-8, UCS-32, wchar_t or Latin-1.
535 * Prototypes for yaz_iconv_-functions moved to separate header
536 include/yaz/yaz-iconv.h.
538 Make a few private functions 'static' in unix.c. This prevents
539 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
541 For ZOOM connection, the options targetImplementation{Id,Name,Version}
542 are set when Init Response is received.
544 New function ZOOM_connection_error_x similar to ZOOM_connection_error
545 but returns diagnostic set as well.
547 New function yaz_strerror which is a portable wrapper for
548 strerror/strerror_r/GetLastMessage.
550 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
551 is returned for MARC. If type is "oai", then OAI MARC is returned.
553 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
558 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
560 Fix bad race conditions on SIGTERM and terminate gracefully in
563 Move retrieval (data1) module to Zebra since nobody seems to be
566 Add GRS-1 render for ZOOM using same format as yaz-client.
570 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
572 Fix broken ESpec handling in data1 module.
574 SGML reader parses comments and makes them part of the data1 tree.
576 Added several type casts so that YAZ compiles as C++ code.
578 ZOOM didn't handle PDU encoding failures properly.
580 Added more Bib-1 diagnostics (approved extensions).
582 GNU configure: better check for iconv.
584 More portable use of accept, getpeername. Check for socklen_t. Use
585 int/size_t if socklen_t is not defined.
589 PQF parser rejects bad queries - including those with extra
590 characters in them. PQF parser used to silently ignore that.
591 Cleaner API for PQF added, which allows you to get detailed
592 error information for bad queries (see yaz/pquery.h).
594 Fixed bug in ZOOM_record_get for type "database".
596 Implemented mini iconv library supporting conversions between
597 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
599 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
603 Fixed ZOOM C record cache so that preferredRecordSyntax and
604 elementSetName is used to check for already fetched records.
608 Added three members in bend_initrequest structure to facilitate
609 character set negotiation.
611 Fixed a bug in frontend server that could cause indefinite
612 loops under rare conditions.
614 Revised character set utilities (charneg.h) so that encoding
615 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
617 For PQF, directive @term <type> sets term type for Scan/Search.
618 Here <type> is general, string, numeric, null. The term type
619 is inherited - just like @attr.
621 New call odr_set_charset that sets character set conversion for
622 international-strings on a ODR stream. Prototype is:
623 int odr_set_charset(ODR o, const char *to, const char *from);
624 The InternationalString is still represented as C string in YAZ
625 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
626 won't). On the protocol level, you can use any encoding.
628 Support for UNIX sockets in ZOOM.
630 Solaris recv sometimes returns errno == ENOENT. It is treated as
631 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
633 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
634 both client and server. Code by Morten Bøgeskov.
638 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
639 that they can be used directly from Visual Basic. You must recompile
640 your windows APP if you're using ZOOM.
642 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
643 Commands "lang" and "charset" sets language and character set respectively.
644 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
645 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
647 Attributes from multiple CCL fields may be OR'ed rather than merged
648 using directive "@field or". Fields are still merged by default -
649 equivalent to "@field merge".
651 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
654 Fixed bug in zget for parameter ExtendedServicesResponse.
660 Added PQF feature: '@attr type=value' may be written as '@type=value'.
662 Client displays USR.1:SearchResult-1 (hits per term).
664 Additional Search Info for search in Generic Frontend Server.
666 Fixed CCL parsing of "field=s".
668 WIN32 installer - using the excellent NSIS software from nullsoft.
670 Fixed CCL parsing of "field = - <number>".
672 Added function yaz_marc_decode that decodes MARC for line mode
673 display or XML (similar to that used by JZKit).
675 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
676 Z39.50. But ISO/ILL was, however.
678 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
679 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

686 New YAZ client features: Command completion and new commands:
687 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
688 Code provided by Jacob Poulsen.
690 New call oid_trav, that visits all registered OIDs via callback.
692 Function ZOOM_record_get now returns const char pointer rather than
693 void pointer. It saves a lot of type casts.
695 For YAZ client, command "auth" now allows you to set authentication
696 in IdPass style. It is enabled when three tokens are given - order
697 is user, group and password.
699 Fix memory leaks in MARC record handling for ZOOM.
701 New option for YAZ client, -k <kilobytes> that sets
702 maximum record size. Similar to -k option for generic frontend
703 server and yaz-ztest.
705 More fixes for scan. Non-zero stepSize handled. OID's fixes.
707 Prefix query parser reports "fail" when bad attribute set is given.
709 Fix in MARC decoder. Proximity logging. Fix for attribute set
710 in scan handler for server. Patches by Shigeru Ishida.
712 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
715 Configure option --with-openssl=<dir> now works when a directory is
716 specified. Patch provided by Morten Bøgeskov.
718 New option for YAZ client, -u <auth>, that sets authentication.
720 ZOOM fix: error information was sometimes "missing", since error
721 was cleared/reset too when it shouldn't.
723 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
727 Scan for ZOOM API. New object ZOOM_scanset. New functions
728 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
729 ZOOM_scanset_destroy.
731 New ZOOM function, ZOOM_connection_last_event, that returns type
732 of last event (such as "receive data", "send data", "apdu received",
735 New ZOOM option, schema, that specifies schema for retrieval.
737 New CCL feature. Qualifiers can be aliases for one or more
738 other qualifiers (if more than one is given, OR is used).
740 ZOOM uses named result sets if target supports it.
742 Two new YAZ client commands: . (dot, which sources a script of YAZ
743 client commands), and ! (to execute shell command.). Implemented
746 Working on Debian packages.
750 YAZ client enables named result sets only if target supports it.
752 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
754 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
755 with key="host" to get same result.
757 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
758 Function Z3950_resultset_record(s) returns references to records
759 "owned" by resultset. To become owner use Z3950_record_clone.
761 Function z_ext_record handles Extended Services. Thanks to
766 CCL Parser fix: ignore token comma when dealing with and-lists.
768 Documentation updates for COMSTACK.
770 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
771 Changed prototype Z3950_records. For some functions, int parameters
772 were changed to size_t.
774 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
777 New MARC decode/display function, marc_display_exl, which properly rejects
778 non-ISO2709 records. YAZ client uses it.
782 Fix bug: local attribute set wasn't set correctly in PQF strings.
786 * Old Z39.50 codecs no longer supported.
788 Added ZOOM C binding. See http://zoom.z3950.org/
790 Renamed states for COMSTACKs to avoid confusion with events.
792 Implemented cs_look and proper cs_rcvconnect.
794 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
796 Configure detects POSIX threads on OpenBSD.
798 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
799 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
801 When error is returned from present handler, non-surrogate diagnostic
802 is returned in present response (and fetch handler is no longer called).
804 * Minor adjustments to pquery parser (PQF). Token characters may be
805 escaped by using backslash (C-style).
807 PQF parser allows string attribute values to be specified. For @attr,
808 non-numeric characters after the equal-sign are treated as strings
809 (e.g. @attr 9=title).
811 CCL trunction character may be defined (@truncation in file)
813 * function zget_ExtendedServicesRequest sets waitAction to
814 waitIfPossible (was wait).
816 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
819 CCL operator names may be set in field definition files (CCL_bibset).
820 See ccl/bib1 for an example.
822 Fixes in ASN.1 compiler for C++ compatibility.
824 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
825 and "op_or" to avoid conflict with C++.
827 Fixed problem with GNU readline detection on Redhat 7.0.
829 Added step-size for Scan backend handler.
831 Fixed bug that made the frontend server crash when no attribute
832 set was specified for scan.
834 Front-end server automatically switches to original working directory
835 when installed as an NT service. Previously -w had to be specified to
838 Added extended attributes for retrieval module (data1), so that data1
839 records carry d1_readXML/SGML attributes. d1_read also supports
840 null-data rules ( <tag/>)
842 On UNIX when POSIX threads are available, a separate library libyazthread
843 is created. Programmers should link with that library and the yaz library
844 when using threads. The reason for the split was that some applications
845 on Linux, such as Apache, doesn't work well when using shared objects that
848 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
849 (or any frontend server) in SSL mode by specifying ssl: followed by
850 address. Only tested on UNIX.
852 Added feature for CCL module. Virtual structure s=al or s=ol generates
853 and-list and or-list respectively instead of phrase search.
857 * Added prefix "yaz_" for the functions log_init.., log_file.. and
858 log_mask_str. This was done to avoid name conflicts with other libraries
859 (such as other PHP extensions).
861 Added raw OID member for preferred record syntax (request_format_raw)
862 and returned record syntax (output_format_raw) for backend fetch method.
864 Config file yaz-config now accepts options so that it returns specific
865 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
867 Shared library support for UNIX using GNU libtool.
869 * Modified backend interface. Request/Response struct's replaced by
870 one read/write C struct. For example bend_fetchrequest and
871 bend_fetchresult have been replaced by single bend_fetch_rr struct.
872 Every handler - even search has to be registered in bend_init
873 handler. This means that the YAZ library no longer refers to
874 external functions and it makes it possible to make the whole
875 thing a single DLL/SO.
877 Added Segment handler for backend server.
879 Added Zmbol/Zebra administrative functions to YAZ client.
881 Threaded frontend server on UNIX (when POSIX Threads are available).
882 Starting the server with option -T enables multi-threading.
886 Added configure option --enable-comp/disable-comp to control use
887 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
888 located in sub directory asn.
890 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
891 in ${exec_prefix}/bin along with the other programs yaz-client and
894 GNU automake used to maintain makefiles.
898 Changed retrieval module so that we can load records with no abstract
899 syntax defined. Tagpaths in these records are fully composed of string
902 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
906 On UNIX, the generated makefile now supports a proper 'make install'.
907 The prefix can be set via GNU configure to set the install location
908 (default is /usr/local).
910 * YAZ programs client and ztest were renamed to yaz-client and
911 yaz-ztest to avoid conflicts when users install YAZ in "standard"
912 locations, such as /usr/bin,/usr/local/bin,etc.
914 * YAZ Header files were moved from include to include/yaz. YAZ Header
915 files are referred to as include <yaz/log.h> rather than <log.h>.
916 The YAZ include path (-I ..) is therefore the same as before. Programmers
917 should update their #include statements or use -Ipath/include/yaz
918 instead. The main motivation for doing this change is that YAZ header files
919 can be installed in "standard" locations /usr/include,/usr/local/include
920 without introducing conflicts, since ALL YAZ header files are stored
921 in subdirectory yaz (under /usr/include for example).
923 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
924 rather than project/workspace files. We switched because project files
925 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
928 Changed name of logging function, logf, to yaz_log, to prevent name
929 clash with some math-log functions. The YAZ header log.h defines logf
930 to yaz_log (#define) so there should be no incompatibilities by this
933 Added bend_start/bend_stop handlers for server. These handler are
934 called on start/stop of server. For windows they are called whenever
935 a service is started/stopped.
937 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
938 a fairly small ASN.1 compiler written in Tcl. The compiler is located
939 in util/yc.tcl. The auto-generated C code structures are, in a few
940 cases, incompatible with the old decoders. There are differences in the
941 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
942 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
943 The preprocessor variable ASN_COMPILED is defined when the compiled
944 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
945 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
946 wish to use the old encoders/decoders you can specify --disable-yc
949 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
950 version so that it supports both new - and old version of DB Update
952 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
953 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
954 change. The name parameter can be set to 0 in which no name is specified
955 for the construction. The macros odr_implicit and odr_explicit sets name
956 parameter to zero for the construction involved. New macros
957 odr_implicit_tag and odr_explicit_tag are similar to the others,
958 except that a name parameter is added. For programmers' that don't use
959 ODR they probably only need to change the call to z_APDU and z_External.
961 Added access control facility by interfacing the TCP wrapper library.
962 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
963 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
964 name of the daemon and enables the access control as specified in
965 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
967 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
968 den Dool <H.M.vdnDool@kub.nl>.
970 Added reference ID parameter to most functions in server API - refer
971 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
973 Changed name of ccl library to libccl.a (was ccl.a).
975 Fixed bug in decoder for Explain (Category TargetInfo).
977 Added support for GNU readline in client. Thanks to Jacob Poulsen
978 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
980 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
981 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
982 IMPLEMENTATION! This change was made to the development version before
983 the ZIG decided to retract the amendment. If any users MUST be
984 compatible with the original Update definition, PLEASE CONTACT US, and
985 we will include a separate definition corresponding to the old Update
986 ES. Note that because of the change to the ASN.1 of the
987 TaskPackageRecordStructure we cannot define a single structure that
988 will support both versions.
990 * Added const modifier to buffer parameter for some ODR/BER encoding
991 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
992 completeWAIS, odr_dumpBER.
994 Fixed bug in client.c which caused a crash when a scanResponse didn't
995 contain positionOfTerm.
997 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
998 * will cause an error in a client if a non-YAZ target sends both a
999 * list of Scan entries and non-surrogate diagnostics.
1001 Retrieval module enhancements. Tag sets may be typed in the reference
1002 to it. From the .abs-file the "tagset" directive takes a third optional
1003 integer type for the tag set referenced. From a .tag-file the "include"
1004 directive takes a third optional type as well. The old "type" directive
1005 in the tag set itself is still recognized but acts as the default type
1008 Backend interface change. Individual Scan terms returned from bend_scan
1009 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1010 in include/backend.h.
1012 Retrieval module enhancements. Multiple tag sets and attribute sets may
1013 be specified in abstract syntax specs. Revised the error/warning for
1014 logging messages reported by the retrieval module when reading the
1017 Object Identifier system (oid_..) changed. The API is backwards
1018 compatible but the oid-routines now allocates new OID's when needed.
1019 Raw OID's may be specified in oid_getvalbyname.
1021 YAZ now uses GNU configure to generate Makefile(s).
1023 * Minor changes in some of the member names of DeleteResultSetRequest and
1024 DeleteResultSetResponse. See include/proto.h.
1026 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1027 and added member 'languages' in TargetInfo (which was missing).
1029 Changed the way attribute sets are handled in the retrieval
1030 module. These are now cached, just like the abstract syntaxes
1033 Changed YAZ so that it links with compiled ASN.1.
1035 Added Explain-schema definitions and mapping routines. The following
1036 Explain categories have been implemented: AttributeDetails,
1037 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1039 Fixed minor bug in Windows version of Server Library.
1041 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1043 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1045 Added EXTERNAL: UNIverse Resource Report (non-standard).
1047 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1048 ENUMERATED and SET OF.
1050 * Added 'const' to some of the char pointer arguments for the
1051 functions, data1_read_node, data1_getelementbytagname,
1052 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1055 Fixed bug in data1_insert_taggeddata - the last_child member of
1056 parent wasn't initialised.
1058 * Changed data1_read_record and data1_read_node so that the supplied
1059 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1060 doesn't refer to any parts of the "SGML"-buffer.
1062 Fixed bug in server library (Windows version of statserv_remove).
1064 * Changed code so that it compiles as C++. The type definition
1065 of Odr_fun which is a member of Odr_arm was changed. The result is,
1066 that an explicit typecast is needed for the fun pointer when
1067 using Odr_arm - as in:
1068 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1070 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1072 Implemented the new structured date and time definition as approved
1073 by the ZIG. Added schemaId element to the specificTag in Espec-1
1074 (also approved at the last ZIG). Thanks to RVDM.
1076 Added some Object identifiers (RVDM).
1078 Changed the Update Extended Service (RVDM).
1080 Added command "refid" to client which specifies referenceId for
1081 the following requests.
1083 Implemented extended service handling for server. See ztest.c
1084 for an example as well as backend.h. New handlers are registerd
1085 in the Init handler.
1087 * Changed interface for sort in server.
1089 Added new members to statserv_options_block. It allows a server
1090 to read options from another source than just the command line. Thanks
1091 to Charles Woodfield.
1093 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1094 renamed to zboolean. Some C++ compilers complained about the name.
1096 Minor changes to gils.abs. Added index 's' (sort) on title
1097 and date/time-last-modified.
1099 --- 1.4pl2 1998/1/30
1101 Fixed bug in server library regarding inetd mode (-i). This bug
1102 was introduced by release 1.4.
1104 --- 1.4pl1 1998/1/29
1106 Added sort facility in client and backend server interface.
1108 Fixed problem with dependencies in Makefile(s).
1110 Fixed bugs for encoders/decoders of extended services and
1113 Implemented sub-tree feature for schemas. Sub-trees are
1114 referenced in *.abs-files. See explain.abs for an example
1115 of the use of this feature.
1117 Modified bib1.att; local attributes for ANY didn't include
1118 ANY itself (only affects use of the retrieval module).
1120 Fixed bug in plain SGML reader in function data1_read_node:
1121 tags with prefix "var" was incorrectly interpreted as variants.
1123 Added feature "sub-schemas" to enable references to - and definitions
1124 of - group of elements.
1126 * Removed member parent from type data1_element (in data1.h).
1128 Implemented function odr_nullval() that returns the value of
1131 * Removed member num_children from data1_node (in data1.h).
1133 Made NT service interface part of the server library. The
1134 function statserv_main uses the NT service when required and
1135 calls the statserv_start / statserv_close routines.
1137 Routine zget_SearchRequest and zget_PresentRequest fills
1138 resultSetName/Id member with "default" instead of "Default".
1140 Fixed memory leak in server. Request queue member wasn't freed.
1142 Fixed nmem_exit so that memory is freed.
1146 Revised the CCL parser utility to be thread safe.
1148 Added function, oid_ent_to_oid, to replace the function
1149 oid_getoidbyent, which is not thread safe.
1151 * Added nmem_init and nmem_exit to initialize and release
1152 NMEM resources. Function nmem_init should be called once in the
1153 initial thread before NMEM/ODR is used. statserv.c and client.c
1154 have been changed accordingly. The change was necessary to make
1155 NMEM thread safe. The NMEM memory pool is shared amongst threads
1156 in a process. Unix-based applications will still work fine without
1159 Added NT Services interface for the the Z39.50 (statserv) Server.
1160 Refer to the ztest.c source on the usage.
1162 Windows 95/NT port using MSVC5.0. Project files are included in the
1165 * Defined new 'global' handle for the retrieval (data1) system. The
1166 new handled, data1_handle, describes the state of the data1 system.
1167 This handle is passed as first argument to virtually all
1168 data1 related routines. The functions data1_create and data1_destroy
1169 creates and destroys a data1 handle respectively.
1171 Added ODR encode stream member to all backend request structures
1172 init, search, scan etc. This stream should be used to allocate all
1173 memory used for the response when thread safe operation is needed.
1175 Changed the comstack utility, cs_addstr, to be thread safe. The
1176 returned hostname string returned by the function is now part the
1179 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1180 function. The cs_straddr takes a COMSTACK handle as argument, so this
1181 function must be used after cs_create and before bind/connect.
1182 This function is thread safe.
1184 Moved test server to 'ztest' directory - generic server code still
1185 in 'server' directory.
1187 Made prefix query (pquery.c) utility thread safe.
1189 Added new function modifier YAZ_EXPORT to 'export' public DLL
1190 functions when using windows (see include/yconfig.h).
1192 Added definitions to the OID database (util/oid.c) (RVDM).
1194 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1196 Added call to ccl_rpn_delete in client program.
1198 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1199 release of RPN structure.
1201 Added support for C++, headers uses extern "C" for public definitions.
1202 With input from RVDM.
1204 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1205 Thanks to Ronald van der Meer (RVDM).
1207 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1209 Added support for private extensions to the OID database
1210 (oid_setprivateoids()). Thanks to RVDM.
1212 Added optional, physical ANY (key replication)
1214 Fixed null-reference problem in GRS-1 output filter.
1216 Proximity operator added to Prefix Query Format (PQF).
1218 In test client command "base" accepts multiple databases.
1220 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1224 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1226 Smallish bug-fixes in the new encoders/decoders (explain).
1228 Bug fixed in DeleteRequest.
1230 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1232 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1234 Added SOIF syntax (using private OID for now) to retrieval module and client.
1236 Added Update extended service.
1238 Added SearchResult-1 additional info structure.
1240 Added optional CCL (ISO8777) interpreter as separate module. Available
1243 --- 1.2 1996/6/10 (1st anniversary release)
1245 Added Summary record syntax. Lightly tested.
1247 Added OPAC record syntax. Untested.
1249 Added ResourceReport service encoders/decoders. Untested.
1251 Fixed bug in z_Unit - wrong tagging on unitSystem.
1253 Fixed bug in the DiagRecs decoder.
1255 Added options for max PDU size and session timeout to frontend-server.
1257 Added documentation of query-language parsers and other supporting utilities.
1259 [frontend-server] Added Attribute set to the bend_scanrequest API.
1261 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1262 surrogate diagnostics were generated.
1264 [retrieval] Allow multiple local values for attribute.
1266 [retrieval] Allow multiple attributes per element in .abs files. index type.
1268 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1270 --- 1.1pl2 1996/4/10
1272 Minor changes, mostly specific to Zebra's requirements (retrieval)
1276 Repaired bug in frontend server when running multiple listening
1277 endpoints in dynamic mode.
1279 z_External() now won't break if a known, ASN.1 value comes encapsulated
1280 in an octet-string. The value will pass through unmodified in an Odr_oct.
1282 Added a bit of code to the demo client to decode & display
1283 ASN.1-structured records represented in the octet-aligned branch of
1284 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1286 Added z_ext_getentbyref() to the ASN module. Doc updated.
1288 * Completed the SCAN definition in the ASN module. This may break SCAN
1289 code based on older YAZ-versions at compile-time. The fix is easy -
1292 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1293 under the SCAN definition. Remember to initialize this, server-people.
1295 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1296 that this does not extend to ODR and ASN.
1298 Comstack allows insertion of established socket (primarily for
1299 inetd-operation of servers). Doc updated.
1301 Front-end server can now start from the inetd in TCP mode. Doc
1304 --- 1.0pl4 1996/1/24
1308 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1309 the rank and record number.
1311 Adjustments to the frontend server.
1313 Fixed diagnostic BER dumper. It ignored the file argument.
1317 Various changes to retrieval module.
1319 Changed the union discriminators of the protocol files from enums to
1320 ints paired with #defines.
1322 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1325 *Changed operator in the RPN structure to 'roperator', again to avoid a
1328 Fixed problems in Explain decoders/encoders.
1330 --- 1.0pl2 1995/12/6
1332 Memory bug in log module fixed.
1334 --- 1.0pl1 1995/12/5
1336 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1338 Bug in Explain DatabaseInfo module fixed.
1340 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1344 The shift to v1.0 signals that we now consider the *core* functionality
1345 of YAZ reasonably stable (the core being more or less equivalent to
1346 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1347 tested (Explain not at all - though that will happen soonish).
1349 Minor changes to code to support Windows port.
1351 Various minor changes after we're getting to use GRS-1 & co. more.
1353 Added Espec-1 format.
1355 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1356 of the protocol and it cannot be selected when encoding (maps into 'string'
1357 when decoding). Needed to talk to some servers.
1359 Demo client can request simple element set names.
1361 Added Diagnostic Format encoders/decoders.
1363 Added simple Close handling to frontend server (no hooks for resource
1364 reporting yet), and demonstration client.
1366 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1368 --- 1.0b3 1995/08/24
1370 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1371 handled incorrectly when records were requested in the searchResponse. This
1372 will only affect you if you use the frontend-server.
1374 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1375 Test-client will ask for and print GRS1. Ztest will return dummy records
1378 Added Explain encoders/decoders to the service-level API. Untested.
1380 Added Extended Services: Item Order encoders and decoders to the Service-
1381 level API. Untested. We could use a recent copy of the pertinent bits
1382 of the ILL protocol to add those bits.
1384 Added diagnostic format 1 encoders/decoders to the service-level API.
1387 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1388 odr_cons.c, which causes a more correct output.
1390 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1391 was always set to 0 when no records were requested in the searchRequest.
1393 * Added better external-handling. This shouldn't harm old code that
1394 *encodes* externals. It can break code that looks for a
1395 'single-ASN1-type' representation, since those types that are known
1396 are now decoded immediately. Look at the SUTRS sample code in
1397 seshigh.c and client.c. Documentation updated.
1399 Handling of structured records in bend_fetchresponse. Length -1 marks
1400 structured record, type is deduced from format field.
1402 --- 1.0b2 1995/06/27
1403 Fairly quick maintenance release to add SUTRS support.
1405 Fixed handling of SUTRS records in the demonstration client.
1407 * Added format field to the bend_fetchrequest and bend_fetchresponce
1408 structures of the backend API (frontend server). When the record is
1409 returned, the value of the format field is mapped to an OID. The
1410 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1411 of the record. The special value VAL_NONE in the bend_request means
1412 that no specific format was requested by the client. Documentation
1413 updated accordingly. Test server (ztest) will return a fixed dummy
1414 SUTRS record if your client requests SUTRS.
1416 Documentation updated accordingly.
1418 You can now set external libraries and RANLIB support in the top-level
1422 First public release.
