1 Possible compatibility problems with earlier versions marked with '*'.
5 Fixed MARC->MARCXML conversion to properly deal with
6 fields, subfields, indicators having non-ASCII characters.
8 Fixed MARC->MARCXML conversion so that ASCII control characters
9 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
12 Added YAZ GFS support for conversion from Z39.50 surrogate
13 diagnostics to SRW surrogate diagnostics.
15 Bug fix: YAZ GFS did not return schema in explainResponse.
19 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
20 now converts recordSchema to elementSetName as well as schema URI.
22 Fixed bug in COMSTACK that prevented HTTP request packages from being
27 Added CCL facility r=r "range" which is similar to r=o "ordered" but
28 does not require white-space before and after the dash in a range, e.g.
29 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
32 Fixed a few AC_TRY_LINK configure tests that did not operate properly
33 due to new GCC removing "redundant" code.
35 Added yaz-client commands scanpos and scanstep that sets preferred
36 position and step-size for scan.
38 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
40 Added CCL utility ccl_qual_buf which parses one or more CCL
41 spec lines in a buffer.
43 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
44 of name and value - ignoring empty lines and comments.
46 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
48 Added odr_get_element_path which returns current element path for an
49 ODR handle. This utility is useful in error handling or user-defined
52 Added ODR_PRINT utility odr_set_stream which is is a more generic
53 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
54 to a write function and pointer to close function. The close function - if
55 non-NULL - will be called during odr_destroy.
57 Fixed bug in CCL parser where truncation char was not removed from
58 right side when truncation=both was in effect.
60 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
65 Fix buffer overrun in CQL parser when dealing with proximity (%).
67 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
68 to UTF-8/UCS conversion is now only based on codetables.xml.
70 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
74 Add support for more "commit changes" in ZOOM (uses Extended Services).
76 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
79 Yet another small fix for configure of SSL.
83 Fix SSL libs for configure when --with-openssl=DIR is given.
87 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
89 SSL comstack now uses yaz.pem certificate file on server side
90 by default. Certificate filename can be configured by calling
91 comstack function cs_set_ssl_certificate_file before cs_bind is used.
93 Fix bug regarding multiple calls to ZOOM_connection_connect.
95 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
97 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
98 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
100 ZOOM now allows inspection of X509 peer certificate for verification.
101 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
103 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
104 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
105 as "modular" but it simplifies things.
107 Added cs_get_peer_certificate to that returns peer X509 PEM.
109 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
110 NULL if SSL is unavailable.
112 Documentation about MARC decoding tools.
114 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
116 --- 2.0.19 2004/03/30

138 --- 2.0.16 2004/03/16 Debian only
140 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
143 Update CQL parser to use new CQL 1.1 modifiers for booleans and

150 Another fix for decoding of XML packed records.
152 --- 2.0.14 2004/02/25
154 Fixes for Chunked encoding. White space not ignored after length spec.
156 Update NS and use default NS for SRW diagnostic elements.
158 --- 2.0.13 2004/02/23
160 Implement ZOOM_resultset_cache_reset which resets record cache.
162 Implement ZOOM_resultset_sort which sorts a result set.
164 Implement chunked HTTP transfer.
166 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
168 --- 2.0.12 2004/02/16
170 Added member 'schema' to bend_explain_rr structure so that backend
171 can specify explain record identifier. Defaults to Zeerex 2.0.
173 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
175 --- 2.0.11 2004/02/16
177 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
180 Added init command for yaz-client which sends "extra" init request.
182 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
183 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
185 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
187 Make ZOOM error code for "invalid query".
189 Fixed compilation for SSL which wasn't properly enabled for all platforms.
191 --- 2.0.10 2004/02/05
193 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
196 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
198 Added option -p <file> to make Generic Frontend Server to write PID file.
200 Added option -D to put Generic Frontend Server in background on its own.
202 Make ZOOM C recognize option "password". If unset, "pass" is used
203 (for backwards compatibility).
205 Fixed a bug in Generic Frontend Server that could make it crash if a
206 client sets characterSetNegotation bit, but didn't pass negotiation stuff
209 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
210 Must be issued before open, in order to be in effect.
212 --- 2.0.9-6 2004/01/12 Debian/Windows
214 Make the SRU server more picky WRT unknown params, etc.
216 Bug fix: ZOOM scan response didn't return displayTerm - when present.
218 New YAZ client command, options, that sets Z39.50 options.
220 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
221 options from a string of tokens (one token for each option bit).
223 Update SRW diagnostic code messages.
225 --- 2.0.9-5 2004/01/07 Debian/Windows
227 Handle user defined stylesheet for SRW/SRU.
229 --- 2.0.9-4 2004/01/06 Debian/Windows
231 Fix bug in decoding of Content-Length.
233 --- 2.0.9-3 2004/01/06 Debian/Windows
235 Fix a bug with decoding of XML packed records.
237 --- 2.0.9-2 2004/01/05 Debian only
239 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
241 Fix bug in SRW/SRU diagnostics decoding.
245 Fixed bug in Generic Frontend Server which could drop records exceeding
246 preferred message size. Reported and fixed by Irina Dijour.
248 Fixed calculation of package size for structured records in Generic
249 Frontend Server. Reported and fixed by Irina Dijour.
251 Fixed namespace for SRW/SRU diagnostics.
253 Fixed SEGV in yaz-client that occured for HTTP connection errors.
257 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
258 this version is incompatible with version 1.0 and older YAZ SRW/SRU
261 CQL changes to reflect recent changes to the specification:
262 * Documentation talks about context sets instead of index sets.
263 * Documentation talks about indexes instead of qualifiers.
264 * The CQL-to-PQF transformer's configuration file now uses
265 "index.set.name = <attributes>" instead of the old form
266 "qualifier.set.name = <attributes>". (Both forms are still
267 understood but the latter is deprecated.)
268 * CQL terms with no explicit index specified are now interpreted as
269 cql.serverChoice instead of srw.serverChoice (which of course
270 behaves exactly the same.)
274 MARC conversion can now generate ISO2709 output in another
275 character set. yaz-marcdump uses this facility if you invoke it
278 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
279 functions from there can be used from C++.
283 Frontend server now transfers memory from decoded packages to stream
286 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
287 references to show up.
289 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
290 the ZOOM Abstract API. The older names for the same options are still
291 also supported for the benefit of old applications.
293 ZOOM-C supports "implementationId" and "implementationVersion" options
294 to go along with "implementationName". These allow the user code to
295 specify identification strings to be sent to servers.
296 Add OID for the new ExtLite attribute set.
298 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
299 as requested/supplid by Ere Maijala <ere@atp.fi>
301 For generic frontend server, reverse the order of
302 "toolkit-supplied / application-supplied" strings sent as implementationId,
303 Name and Version. Also, remove the spaces around the slash. This brings
304 the GFS in line with the behaviour of ZOOM-C on the client side.
306 Add function ZOOM_scanset_display_term.
308 yaz-client shows scan displayTerm if present.
310 Utility yaz-iconv is now installed by default along with the man page
313 Extend configure check for OpenSSL to use pkg-config where available (such
316 Incorporate patch by Morten Bogeskov which allows a Unix file socket
317 server to specify uid/gid/mask for socket using the format
318 unix:[user=uid,][group=gid,][umask=mask,]file=path
319 If file= is omitted the existing format is assumed, e.g.
321 in which case the mask is 0666 (rw for everybody).
323 Major restructure of YAZ source. All source in libyaz is in src directory.
324 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
325 util (utility programs such as ASN.1 compiler, yaz-marcdump).
327 Added man page for utility yaz-marcdump (used to be called marcdump).
328 yaz-marcdump is installed by 'make install'.
330 Fixed a memory leak in Generic Frontend Server that occurred when decoding
331 of incoming package failed.
333 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
335 Change prototype of odr_perror: add const to message string.
337 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
339 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
340 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
341 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
342 DNS lookup. There should not be any compatibility problems with this
343 assuming that blocking=1 or 0 is used.
345 Fix bad reference in UNIX comstack in function cs_addrstr.
347 Fix for compilation on AIX.
349 The generic front-end server (server/seshigh.c) now supports returning
350 Init diagnostics to the client in User-information-field, in
351 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
356 Allow any CQL relation (not just all,any,exact,scr).
358 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
359 that features the same UI.
361 Implemented command update0 in YAZ client which is equivalent to
362 update but uses old of Ext Update ASN.1.
364 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
365 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
366 Previously no OID was used for this info.
368 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
369 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
370 returns 'malformed search term' otherwise.
372 SortResponse member resultCount now set to NULL in sort handler of
375 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
378 Add three new utility functions for translating OIDs between various
379 formats -- symbolic name such as "Usmarc", minus-1-terminated int
380 arrays and dotted strings such as "1.2.840.10003.9.5.1":
381 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
382 char *oid_to_dotstring(const int *oid, char *oidbuf);
383 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
385 Reverted modifications for ES Update definition for z_IU0Update
386 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
387 is back to YAZ 2.0.2.
389 String value attributes for CCL parser.
391 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
392 which their FirstSearch server returns in Init responses, sometimes
393 carrying useful diagnostic information when Init fails. This has the
394 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
395 "z39.50/oclcui.asn", where its definition is somewhat different from
396 what OCLC document on their web-site, as required to interoperate with
399 Support for anonymous authentication in yaz-client. Use the command
402 * Fix the OID of the Index Data-local "admin" Extended Service from
403 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
404 the 1000, which indicates a locally-defined OID, was a mistake.
408 Fix CCL directive @case handling so that it affects string match for
409 both CCL keywords and qualifiers.
411 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
412 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
413 Decoder has been updated with ASN.1 changes as listed in
414 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
415 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
416 z_IUUpdate, remains unchanged.
418 ZOOM_record_get may now return a record in a specific character set.
419 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
420 "from" is the character set of record as returned by target. "to" is
421 the character set to be returned. If omitted, "to" is UTF-8.
423 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
425 New ODR utility, odr_getelement, which returns name of element for
426 which encoding/decoding failed.
428 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
429 in cases where a required element was omitted.
431 Bug fix: some MARC8 sequences were not converted.
433 New ZOOM option "step" which specifies number of records to be
434 retrieved in one chunk. Used in conjunction with "start" and "count".
436 SRW support for yaz-client. Use scheme http: to use it, e.g.
439 yaz-client no longer does (un)intelligent character set conversions
440 by default. Can be enabled with charset and marc_charset commands.
442 xmalloc trace fix for 64-bit systems such as DEC alpha.
444 Solaris 2.6 compile fix.
446 New function, cql_strerror() translates SRW error codes, as returned
447 by cql_transform_error(), into human-readable English strings. Used
448 in yaz-client diagnostics when appropriate.
450 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
451 converts it into a type-1 query which is sent to the server. This
452 makes CQL available for use with all Z-servers, as opposed to the tiny
453 minority that can handle CQL queries themselves.
457 New Debian package layout similar to the Redhat Package layout.
459 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
460 and search result respectively.
464 Redhat package is now several packages: libyaz (runtime libraries),
465 libyaz-devel (development and documentation, and yaz (utility programs).
466 Package spec file by Morten Bøgeskov.
468 New member 'schema' in struct bend_fetch_rr which the name of requested
469 schema (SRW/SRU) for record (or NULL if none was given). The fetch
470 handler MAY set this to reflect the schema of the returned record.
472 New member 'display_term' in struct scan_entry. GFS now sets member entries
473 and allocates scan entries to be filled by user scan handler. In previous
474 version, entries member was allocated by the scan handler. That still works,
475 but the GFS will ignore member display_term - assuming it was NOT set by
476 the handler. The fact that the GFS now allocates the entries both allows
477 for new members and makes a scan handler easier to write.
479 Fix CQL lex buffer overflow.
481 SRW/SRU recordPacking. For SRW default recordPacking is string. For
482 SRU default recordPacking is string.
484 SRU protocol support for frontend server.
486 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
488 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
490 Added scan for the ZOOM shell (zoomsh).
494 * String Identifers for Schemas (Amendment 5).
495 http://lcweb.loc.gov/z3950/agency/amend/am5.html
496 Old definition for schema
497 Odr_oid *schema; /* OPT */
502 Z_InternationalString *uri;
503 #define Z_Schema_oid 1
504 #define Z_Schema_uri 2
507 * resultCount parameter to Sort Response (Amendment 1).
508 http://lcweb.loc.gov/z3950/agency/amend/am1.html
510 Support for SRW 1.0 over HTTP. This is an optional feature and
511 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
514 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
515 on the same port. SRW SearchRetrieveRequests are mapped
516 to bend_init,bend_search,bend_fetch,bend_close.
518 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
520 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
521 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
523 ZOOM connections are SRW based if schem http is used for hostname
524 in connect, e.g. z = ZOOM_connection_new("http://myserver");
525 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
527 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
528 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
529 distance=n, order=true/false, relation=le, prox unit=word. If
530 n is omitted, distance 1 is used.
532 Fixed problem with C compiler include path in wrong order.
534 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
535 on Solaris. Patch from Ko van der Sloot.
537 New MARC decode API. All new functions operate on a yaz_marc_t
538 handle. The most important new functions are: yaz_marc_create,
539 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
540 decode and destroy respectively. Decoder can produce formats
541 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
542 include/yaz/marcdisp.h.
544 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
545 to UTF-8, UCS-32, wchar_t or Latin-1.
547 * Prototypes for yaz_iconv_-functions moved to separate header
548 include/yaz/yaz-iconv.h.
550 Make a few private functions 'static' in unix.c. This prevents
551 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
553 For ZOOM connection, the options targetImplementation{Id,Name,Version}
554 are set when Init Response is received.
556 New function ZOOM_connection_error_x similar to ZOOM_connection_error
557 but returns diagnostic set as well.
559 New function yaz_strerror which is a portable wrapper for
560 strerror/strerror_r/GetLastMessage.
562 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
563 is returned for MARC. If type is "oai", then OAI MARC is returned.
565 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
570 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
572 Fix bad race conditions on SIGTERM and terminate gracefully in
575 Move retrieval (data1) module to Zebra since nobody seems to be
578 Add GRS-1 render for ZOOM using same format as yaz-client.
582 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
584 Fix broken ESpec handling in data1 module.
586 SGML reader parses comments and makes them part of the data1 tree.
588 Added several type casts so that YAZ compiles as C++ code.
590 ZOOM didn't handle PDU encoding failures properly.
592 Added more Bib-1 diagnostics (approved extensions).
594 GNU configure: better check for iconv.
596 More portable use of accept, getpeername. Check for socklen_t. Use
597 int/size_t if socklen_t is not defined.
601 PQF parser rejects bad queries - including those with extra
602 characters in them. PQF parser used to silently ignore that.
603 Cleaner API for PQF added, which allows you to get detailed
604 error information for bad queries (see yaz/pquery.h).
606 Fixed bug in ZOOM_record_get for type "database".
608 Implemented mini iconv library supporting conversions between
609 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
611 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
615 Fixed ZOOM C record cache so that preferredRecordSyntax and
616 elementSetName is used to check for already fetched records.
620 Added three members in bend_initrequest structure to facilitate
621 character set negotiation.
623 Fixed a bug in frontend server that could cause indefinite
624 loops under rare conditions.
626 Revised character set utilities (charneg.h) so that encoding
627 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
629 For PQF, directive @term <type> sets term type for Scan/Search.
630 Here <type> is general, string, numeric, null. The term type
631 is inherited - just like @attr.
633 New call odr_set_charset that sets character set conversion for
634 international-strings on a ODR stream. Prototype is:
635 int odr_set_charset(ODR o, const char *to, const char *from);
636 The InternationalString is still represented as C string in YAZ
637 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
638 won't). On the protocol level, you can use any encoding.
640 Support for UNIX sockets in ZOOM.
642 Solaris recv sometimes returns errno == ENOENT. It is treated as
643 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
645 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
646 both client and server. Code by Morten Bøgeskov.
650 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
651 that they can be used directly from Visual Basic. You must recompile
652 your windows APP if you're using ZOOM.
654 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
655 Commands "lang" and "charset" sets language and character set respectively.
656 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
657 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
659 Attributes from multiple CCL fields may be OR'ed rather than merged
660 using directive "@field or". Fields are still merged by default -
661 equivalent to "@field merge".
663 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
666 Fixed bug in zget for parameter ExtendedServicesResponse.
672 Added PQF feature: '@attr type=value' may be written as '@type=value'.
674 Client displays USR.1:SearchResult-1 (hits per term).
676 Additional Search Info for search in Generic Frontend Server.
678 Fixed CCL parsing of "field=s".
680 WIN32 installer - using the excellent NSIS software from nullsoft.
682 Fixed CCL parsing of "field = - <number>".
684 Added function yaz_marc_decode that decodes MARC for line mode
685 display or XML (similar to that used by JZKit).
687 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
688 Z39.50. But ISO/ILL was, however.
690 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
691 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

698 New YAZ client features: Command completion and new commands:
699 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
700 Code provided by Jacob Poulsen.
702 New call oid_trav, that visits all registered OIDs via callback.
704 Function ZOOM_record_get now returns const char pointer rather than
705 void pointer. It saves a lot of type casts.
707 For YAZ client, command "auth" now allows you to set authentication
708 in IdPass style. It is enabled when three tokens are given - order
709 is user, group and password.
711 Fix memory leaks in MARC record handling for ZOOM.
713 New option for YAZ client, -k <kilobytes> that sets
714 maximum record size. Similar to -k option for generic frontend
715 server and yaz-ztest.
717 More fixes for scan. Non-zero stepSize handled. OID's fixes.
719 Prefix query parser reports "fail" when bad attribute set is given.
721 Fix in MARC decoder. Proximity logging. Fix for attribute set
722 in scan handler for server. Patches by Shigeru Ishida.
724 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
727 Configure option --with-openssl=<dir> now works when a directory is
728 specified. Patch provided by Morten Bøgeskov.
730 New option for YAZ client, -u <auth>, that sets authentication.
732 ZOOM fix: error information was sometimes "missing", since error
733 was cleared/reset too when it shouldn't.
735 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
739 Scan for ZOOM API. New object ZOOM_scanset. New functions
740 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
741 ZOOM_scanset_destroy.
743 New ZOOM function, ZOOM_connection_last_event, that returns type
744 of last event (such as "receive data", "send data", "apdu received",
747 New ZOOM option, schema, that specifies schema for retrieval.
749 New CCL feature. Qualifiers can be aliases for one or more
750 other qualifiers (if more than one is given, OR is used).
752 ZOOM uses named result sets if target supports it.
754 Two new YAZ client commands: . (dot, which sources a script of YAZ
755 client commands), and ! (to execute shell command.). Implemented
758 Working on Debian packages.
762 YAZ client enables named result sets only if target supports it.
764 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
766 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
767 with key="host" to get same result.
769 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
770 Function Z3950_resultset_record(s) returns references to records
771 "owned" by resultset. To become owner use Z3950_record_clone.
773 Function z_ext_record handles Extended Services. Thanks to
778 CCL Parser fix: ignore token comma when dealing with and-lists.
780 Documentation updates for COMSTACK.
782 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
783 Changed prototype Z3950_records. For some functions, int parameters
784 were changed to size_t.
786 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
789 New MARC decode/display function, marc_display_exl, which properly rejects
790 non-ISO2709 records. YAZ client uses it.
794 Fix bug: local attribute set wasn't set correctly in PQF strings.
798 * Old Z39.50 codecs no longer supported.
800 Added ZOOM C binding. See http://zoom.z3950.org/
802 Renamed states for COMSTACKs to avoid confusion with events.
804 Implemented cs_look and proper cs_rcvconnect.
806 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
808 Configure detects POSIX threads on OpenBSD.
810 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
811 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
813 When error is returned from present handler, non-surrogate diagnostic
814 is returned in present response (and fetch handler is no longer called).
816 * Minor adjustments to pquery parser (PQF). Token characters may be
817 escaped by using backslash (C-style).
819 PQF parser allows string attribute values to be specified. For @attr,
820 non-numeric characters after the equal-sign are treated as strings
821 (e.g. @attr 9=title).
823 CCL trunction character may be defined (@truncation in file)
825 * function zget_ExtendedServicesRequest sets waitAction to
826 waitIfPossible (was wait).
828 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
831 CCL operator names may be set in field definition files (CCL_bibset).
832 See ccl/bib1 for an example.
834 Fixes in ASN.1 compiler for C++ compatibility.
836 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
837 and "op_or" to avoid conflict with C++.
839 Fixed problem with GNU readline detection on Redhat 7.0.
841 Added step-size for Scan backend handler.
843 Fixed bug that made the frontend server crash when no attribute
844 set was specified for scan.
846 Front-end server automatically switches to original working directory
847 when installed as an NT service. Previously -w had to be specified to
850 Added extended attributes for retrieval module (data1), so that data1
851 records carry d1_readXML/SGML attributes. d1_read also supports
852 null-data rules ( <tag/>)
854 On UNIX when POSIX threads are available, a separate library libyazthread
855 is created. Programmers should link with that library and the yaz library
856 when using threads. The reason for the split was that some applications
857 on Linux, such as Apache, doesn't work well when using shared objects that
860 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
861 (or any frontend server) in SSL mode by specifying ssl: followed by
862 address. Only tested on UNIX.
864 Added feature for CCL module. Virtual structure s=al or s=ol generates
865 and-list and or-list respectively instead of phrase search.
869 * Added prefix "yaz_" for the functions log_init.., log_file.. and
870 log_mask_str. This was done to avoid name conflicts with other libraries
871 (such as other PHP extensions).
873 Added raw OID member for preferred record syntax (request_format_raw)
874 and returned record syntax (output_format_raw) for backend fetch method.
876 Config file yaz-config now accepts options so that it returns specific
877 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
879 Shared library support for UNIX using GNU libtool.
881 * Modified backend interface. Request/Response struct's replaced by
882 one read/write C struct. For example bend_fetchrequest and
883 bend_fetchresult have been replaced by single bend_fetch_rr struct.
884 Every handler - even search has to be registered in bend_init
885 handler. This means that the YAZ library no longer refers to
886 external functions and it makes it possible to make the whole
887 thing a single DLL/SO.
889 Added Segment handler for backend server.
891 Added Zmbol/Zebra administrative functions to YAZ client.
893 Threaded frontend server on UNIX (when POSIX Threads are available).
894 Starting the server with option -T enables multi-threading.
898 Added configure option --enable-comp/disable-comp to control use
899 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
900 located in sub directory asn.
902 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
903 in ${exec_prefix}/bin along with the other programs yaz-client and
906 GNU automake used to maintain makefiles.
910 Changed retrieval module so that we can load records with no abstract
911 syntax defined. Tagpaths in these records are fully composed of string
914 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
918 On UNIX, the generated makefile now supports a proper 'make install'.
919 The prefix can be set via GNU configure to set the install location
920 (default is /usr/local).
922 * YAZ programs client and ztest were renamed to yaz-client and
923 yaz-ztest to avoid conflicts when users install YAZ in "standard"
924 locations, such as /usr/bin,/usr/local/bin,etc.
926 * YAZ Header files were moved from include to include/yaz. YAZ Header
927 files are referred to as include <yaz/log.h> rather than <log.h>.
928 The YAZ include path (-I ..) is therefore the same as before. Programmers
929 should update their #include statements or use -Ipath/include/yaz
930 instead. The main motivation for doing this change is that YAZ header files
931 can be installed in "standard" locations /usr/include,/usr/local/include
932 without introducing conflicts, since ALL YAZ header files are stored
933 in subdirectory yaz (under /usr/include for example).
935 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
936 rather than project/workspace files. We switched because project files
937 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
940 Changed name of logging function, logf, to yaz_log, to prevent name
941 clash with some math-log functions. The YAZ header log.h defines logf
942 to yaz_log (#define) so there should be no incompatibilities by this
945 Added bend_start/bend_stop handlers for server. These handler are
946 called on start/stop of server. For windows they are called whenever
947 a service is started/stopped.
949 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
950 a fairly small ASN.1 compiler written in Tcl. The compiler is located
951 in util/yc.tcl. The auto-generated C code structures are, in a few
952 cases, incompatible with the old decoders. There are differences in the
953 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
954 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
955 The preprocessor variable ASN_COMPILED is defined when the compiled
956 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
957 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
958 wish to use the old encoders/decoders you can specify --disable-yc
961 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
962 version so that it supports both new - and old version of DB Update
964 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
965 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
966 change. The name parameter can be set to 0 in which no name is specified
967 for the construction. The macros odr_implicit and odr_explicit sets name
968 parameter to zero for the construction involved. New macros
969 odr_implicit_tag and odr_explicit_tag are similar to the others,
970 except that a name parameter is added. For programmers' that don't use
971 ODR they probably only need to change the call to z_APDU and z_External.
973 Added access control facility by interfacing the TCP wrapper library.
974 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
975 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
976 name of the daemon and enables the access control as specified in
977 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
979 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
980 den Dool <H.M.vdnDool@kub.nl>.
982 Added reference ID parameter to most functions in server API - refer
983 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
985 Changed name of ccl library to libccl.a (was ccl.a).
987 Fixed bug in decoder for Explain (Category TargetInfo).
989 Added support for GNU readline in client. Thanks to Jacob Poulsen
990 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
992 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
993 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
994 IMPLEMENTATION! This change was made to the development version before
995 the ZIG decided to retract the amendment. If any users MUST be
996 compatible with the original Update definition, PLEASE CONTACT US, and
997 we will include a separate definition corresponding to the old Update
998 ES. Note that because of the change to the ASN.1 of the
999 TaskPackageRecordStructure we cannot define a single structure that
1000 will support both versions.
1002 * Added const modifier to buffer parameter for some ODR/BER encoding
1003 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1004 completeWAIS, odr_dumpBER.
1006 Fixed bug in client.c which caused a crash when a scanResponse didn't
1007 contain positionOfTerm.
1009 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1010 * will cause an error in a client if a non-YAZ target sends both a
1011 * list of Scan entries and non-surrogate diagnostics.
1013 Retrieval module enhancements. Tag sets may be typed in the reference
1014 to it. From the .abs-file the "tagset" directive takes a third optional
1015 integer type for the tag set referenced. From a .tag-file the "include"
1016 directive takes a third optional type as well. The old "type" directive
1017 in the tag set itself is still recognized but acts as the default type
1020 Backend interface change. Individual Scan terms returned from bend_scan
1021 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1022 in include/backend.h.
1024 Retrieval module enhancements. Multiple tag sets and attribute sets may
1025 be specified in abstract syntax specs. Revised the error/warning for
1026 logging messages reported by the retrieval module when reading the
1029 Object Identifier system (oid_..) changed. The API is backwards
1030 compatible but the oid-routines now allocates new OID's when needed.
1031 Raw OID's may be specified in oid_getvalbyname.
1033 YAZ now uses GNU configure to generate Makefile(s).
1035 * Minor changes in some of the member names of DeleteResultSetRequest and
1036 DeleteResultSetResponse. See include/proto.h.
1038 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1039 and added member 'languages' in TargetInfo (which was missing).
1041 Changed the way attribute sets are handled in the retrieval
1042 module. These are now cached, just like the abstract syntaxes
1045 Changed YAZ so that it links with compiled ASN.1.
1047 Added Explain-schema definitions and mapping routines. The following
1048 Explain categories have been implemented: AttributeDetails,
1049 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1051 Fixed minor bug in Windows version of Server Library.
1053 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1055 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1057 Added EXTERNAL: UNIverse Resource Report (non-standard).
1059 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1060 ENUMERATED and SET OF.
1062 * Added 'const' to some of the char pointer arguments for the
1063 functions, data1_read_node, data1_getelementbytagname,
1064 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1067 Fixed bug in data1_insert_taggeddata - the last_child member of
1068 parent wasn't initialised.
1070 * Changed data1_read_record and data1_read_node so that the supplied
1071 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1072 doesn't refer to any parts of the "SGML"-buffer.
1074 Fixed bug in server library (Windows version of statserv_remove).
1076 * Changed code so that it compiles as C++. The type definition
1077 of Odr_fun which is a member of Odr_arm was changed. The result is,
1078 that an explicit typecast is needed for the fun pointer when
1079 using Odr_arm - as in:
1080 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1082 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1084 Implemented the new structured date and time definition as approved
1085 by the ZIG. Added schemaId element to the specificTag in Espec-1
1086 (also approved at the last ZIG). Thanks to RVDM.
1088 Added some Object identifiers (RVDM).
1090 Changed the Update Extended Service (RVDM).
1092 Added command "refid" to client which specifies referenceId for
1093 the following requests.
1095 Implemented extended service handling for server. See ztest.c
1096 for an example as well as backend.h. New handlers are registerd
1097 in the Init handler.
1099 * Changed interface for sort in server.
1101 Added new members to statserv_options_block. It allows a server
1102 to read options from another source than just the command line. Thanks
1103 to Charles Woodfield.
1105 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1106 renamed to zboolean. Some C++ compilers complained about the name.
1108 Minor changes to gils.abs. Added index 's' (sort) on title
1109 and date/time-last-modified.
1111 --- 1.4pl2 1998/1/30
1113 Fixed bug in server library regarding inetd mode (-i). This bug
1114 was introduced by release 1.4.
1116 --- 1.4pl1 1998/1/29
1118 Added sort facility in client and backend server interface.
1120 Fixed problem with dependencies in Makefile(s).
1122 Fixed bugs for encoders/decoders of extended services and
1125 Implemented sub-tree feature for schemas. Sub-trees are
1126 referenced in *.abs-files. See explain.abs for an example
1127 of the use of this feature.
1129 Modified bib1.att; local attributes for ANY didn't include
1130 ANY itself (only affects use of the retrieval module).
1132 Fixed bug in plain SGML reader in function data1_read_node:
1133 tags with prefix "var" was incorrectly interpreted as variants.
1135 Added feature "sub-schemas" to enable references to - and definitions
1136 of - group of elements.
1138 * Removed member parent from type data1_element (in data1.h).
1140 Implemented function odr_nullval() that returns the value of
1143 * Removed member num_children from data1_node (in data1.h).
1145 Made NT service interface part of the server library. The
1146 function statserv_main uses the NT service when required and
1147 calls the statserv_start / statserv_close routines.
1149 Routine zget_SearchRequest and zget_PresentRequest fills
1150 resultSetName/Id member with "default" instead of "Default".
1152 Fixed memory leak in server. Request queue member wasn't freed.
1154 Fixed nmem_exit so that memory is freed.
1158 Revised the CCL parser utility to be thread safe.
1160 Added function, oid_ent_to_oid, to replace the function
1161 oid_getoidbyent, which is not thread safe.
1163 * Added nmem_init and nmem_exit to initialize and release
1164 NMEM resources. Function nmem_init should be called once in the
1165 initial thread before NMEM/ODR is used. statserv.c and client.c
1166 have been changed accordingly. The change was necessary to make
1167 NMEM thread safe. The NMEM memory pool is shared amongst threads
1168 in a process. Unix-based applications will still work fine without
1171 Added NT Services interface for the the Z39.50 (statserv) Server.
1172 Refer to the ztest.c source on the usage.
1174 Windows 95/NT port using MSVC5.0. Project files are included in the
1177 * Defined new 'global' handle for the retrieval (data1) system. The
1178 new handled, data1_handle, describes the state of the data1 system.
1179 This handle is passed as first argument to virtually all
1180 data1 related routines. The functions data1_create and data1_destroy
1181 creates and destroys a data1 handle respectively.
1183 Added ODR encode stream member to all backend request structures
1184 init, search, scan etc. This stream should be used to allocate all
1185 memory used for the response when thread safe operation is needed.
1187 Changed the comstack utility, cs_addstr, to be thread safe. The
1188 returned hostname string returned by the function is now part the
1191 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1192 function. The cs_straddr takes a COMSTACK handle as argument, so this
1193 function must be used after cs_create and before bind/connect.
1194 This function is thread safe.
1196 Moved test server to 'ztest' directory - generic server code still
1197 in 'server' directory.
1199 Made prefix query (pquery.c) utility thread safe.
1201 Added new function modifier YAZ_EXPORT to 'export' public DLL
1202 functions when using windows (see include/yconfig.h).
1204 Added definitions to the OID database (util/oid.c) (RVDM).
1206 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1208 Added call to ccl_rpn_delete in client program.
1210 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1211 release of RPN structure.
1213 Added support for C++, headers uses extern "C" for public definitions.
1214 With input from RVDM.
1216 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1217 Thanks to Ronald van der Meer (RVDM).
1219 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1221 Added support for private extensions to the OID database
1222 (oid_setprivateoids()). Thanks to RVDM.
1224 Added optional, physical ANY (key replication)
1226 Fixed null-reference problem in GRS-1 output filter.
1228 Proximity operator added to Prefix Query Format (PQF).
1230 In test client command "base" accepts multiple databases.
1232 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1236 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1238 Smallish bug-fixes in the new encoders/decoders (explain).
1240 Bug fixed in DeleteRequest.
1242 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1244 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1246 Added SOIF syntax (using private OID for now) to retrieval module and client.
1248 Added Update extended service.
1250 Added SearchResult-1 additional info structure.
1252 Added optional CCL (ISO8777) interpreter as separate module. Available
1255 --- 1.2 1996/6/10 (1st anniversary release)
1257 Added Summary record syntax. Lightly tested.
1259 Added OPAC record syntax. Untested.
1261 Added ResourceReport service encoders/decoders. Untested.
1263 Fixed bug in z_Unit - wrong tagging on unitSystem.
1265 Fixed bug in the DiagRecs decoder.
1267 Added options for max PDU size and session timeout to frontend-server.
1269 Added documentation of query-language parsers and other supporting utilities.
1271 [frontend-server] Added Attribute set to the bend_scanrequest API.
1273 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1274 surrogate diagnostics were generated.
1276 [retrieval] Allow multiple local values for attribute.
1278 [retrieval] Allow multiple attributes per element in .abs files. index type.
1280 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1282 --- 1.1pl2 1996/4/10
1284 Minor changes, mostly specific to Zebra's requirements (retrieval)
1288 Repaired bug in frontend server when running multiple listening
1289 endpoints in dynamic mode.
1291 z_External() now won't break if a known, ASN.1 value comes encapsulated
1292 in an octet-string. The value will pass through unmodified in an Odr_oct.
1294 Added a bit of code to the demo client to decode & display
1295 ASN.1-structured records represented in the octet-aligned branch of
1296 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1298 Added z_ext_getentbyref() to the ASN module. Doc updated.
1300 * Completed the SCAN definition in the ASN module. This may break SCAN
1301 code based on older YAZ-versions at compile-time. The fix is easy -
1304 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1305 under the SCAN definition. Remember to initialize this, server-people.
1307 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1308 that this does not extend to ODR and ASN.
1310 Comstack allows insertion of established socket (primarily for
1311 inetd-operation of servers). Doc updated.
1313 Front-end server can now start from the inetd in TCP mode. Doc
1316 --- 1.0pl4 1996/1/24
1320 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1321 the rank and record number.
1323 Adjustments to the frontend server.
1325 Fixed diagnostic BER dumper. It ignored the file argument.
1329 Various changes to retrieval module.
1331 Changed the union discriminators of the protocol files from enums to
1332 ints paired with #defines.
1334 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1337 *Changed operator in the RPN structure to 'roperator', again to avoid a
1340 Fixed problems in Explain decoders/encoders.
1342 --- 1.0pl2 1995/12/6
1344 Memory bug in log module fixed.
1346 --- 1.0pl1 1995/12/5
1348 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1350 Bug in Explain DatabaseInfo module fixed.
1352 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1356 The shift to v1.0 signals that we now consider the *core* functionality
1357 of YAZ reasonably stable (the core being more or less equivalent to
1358 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1359 tested (Explain not at all - though that will happen soonish).
1361 Minor changes to code to support Windows port.
1363 Various minor changes after we're getting to use GRS-1 & co. more.
1365 Added Espec-1 format.
1367 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1368 of the protocol and it cannot be selected when encoding (maps into 'string'
1369 when decoding). Needed to talk to some servers.
1371 Demo client can request simple element set names.
1373 Added Diagnostic Format encoders/decoders.
1375 Added simple Close handling to frontend server (no hooks for resource
1376 reporting yet), and demonstration client.
1378 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1380 --- 1.0b3 1995/08/24
1382 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1383 handled incorrectly when records were requested in the searchResponse. This
1384 will only affect you if you use the frontend-server.
1386 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1387 Test-client will ask for and print GRS1. Ztest will return dummy records
1390 Added Explain encoders/decoders to the service-level API. Untested.
1392 Added Extended Services: Item Order encoders and decoders to the Service-
1393 level API. Untested. We could use a recent copy of the pertinent bits
1394 of the ILL protocol to add those bits.
1396 Added diagnostic format 1 encoders/decoders to the service-level API.
1399 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1400 odr_cons.c, which causes a more correct output.
1402 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1403 was always set to 0 when no records were requested in the searchRequest.
1405 * Added better external-handling. This shouldn't harm old code that
1406 *encodes* externals. It can break code that looks for a
1407 'single-ASN1-type' representation, since those types that are known
1408 are now decoded immediately. Look at the SUTRS sample code in
1409 seshigh.c and client.c. Documentation updated.
1411 Handling of structured records in bend_fetchresponse. Length -1 marks
1412 structured record, type is deduced from format field.
1414 --- 1.0b2 1995/06/27
1415 Fairly quick maintenance release to add SUTRS support.
1417 Fixed handling of SUTRS records in the demonstration client.
1419 * Added format field to the bend_fetchrequest and bend_fetchresponce
1420 structures of the backend API (frontend server). When the record is
1421 returned, the value of the format field is mapped to an OID. The
1422 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1423 of the record. The special value VAL_NONE in the bend_request means
1424 that no specific format was requested by the client. Documentation
1425 updated accordingly. Test server (ztest) will return a fixed dummy
1426 SUTRS record if your client requests SUTRS.
1428 Documentation updated accordingly.
1430 You can now set external libraries and RANLIB support in the top-level
1434 First public release.
