1 Possible compatibility problems with earlier versions marked with '*'.
3 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
5 Added CCL utility ccl_qual_buf which parses one or more CCL
6 spec lines in a buffer.
8 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
9 of name and value - ignoring empty lines and comments.
11 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
13 Added odr_get_element_path which returns current element path for an
14 ODR handle. This utility is useful in error handling or user-defined
17 Added ODR_PRINT utility odr_set_stream which is is a more generic
18 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
19 to a write function and pointer to close function. The close function - if
20 non-NULL - will be called during odr_destroy.
22 Fixed bug in CCL parser where truncation char was not removed from
23 right side when truncation=both was in effect.
25 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
30 Fix buffer overrun in CQL parser when dealing with proximity (%).
32 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
33 to UTF-8/UCS conversion is now only based on codetables.xml.
35 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
39 Add support for more "commit changes" in ZOOM (uses Extended Services).
41 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
44 Yet another small fix for configure of SSL.
48 Fix SSL libs for configure when --with-openssl=DIR is given.
52 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
54 SSL comstack now uses yaz.pem certificate file on server side
55 by default. Certificate filename can be configured by calling
56 comstack function cs_set_ssl_certificate_file before cs_bind is used.
58 Fix bug regarding multiple calls to ZOOM_connection_connect.
60 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
62 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
63 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
65 ZOOM now allows inspection of X509 peer certificate for verification.
66 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
68 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
69 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
70 as "modular" but it simplifies things.
72 Added cs_get_peer_certificate to that returns peer X509 PEM.
74 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
75 NULL if SSL is unavailable.
77 Documentation about MARC decoding tools.
79 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
83 Rename CHANGELOG to NEWS to follow GNU style packing.
85 Fix bug with missing initialization of member in init_diagnostics.
86 This bug affects threaded version of GFS server.
90 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
93 Ensure zlib.dll is packed with Windows install.
97 Fix encoding of xsd:string to use text instead of CDATA.
99 Fix endless loop in CQL parser with unbalanced ".
101 Use a more compact way to store MARC-8 conversion tables.
103 --- 2.0.16 2004/03/16 Debian only
105 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
108 Update CQL parser to use new CQL 1.1 modifiers for booleans and
113 --- 2.0.15 2004/03/01
115 Another fix for decoding of XML packed records.
117 --- 2.0.14 2004/02/25
119 Fixes for Chunked encoding. White space not ignored after length spec.
121 Update NS and use default NS for SRW diagnostic elements.
123 --- 2.0.13 2004/02/23
125 Implement ZOOM_resultset_cache_reset which resets record cache.
127 Implement ZOOM_resultset_sort which sorts a result set.
129 Implement chunked HTTP transfer.
131 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
133 --- 2.0.12 2004/02/16
135 Added member 'schema' to bend_explain_rr structure so that backend
136 can specify explain record identifier. Defaults to Zeerex 2.0.
138 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
140 --- 2.0.11 2004/02/16
142 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
145 Added init command for yaz-client which sends "extra" init request.
147 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
148 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
150 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
152 Make ZOOM error code for "invalid query".
154 Fixed compilation for SSL which wasn't properly enabled for all platforms.
156 --- 2.0.10 2004/02/05
158 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
161 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
163 Added option -p <file> to make Generic Frontend Server to write PID file.
165 Added option -D to put Generic Frontend Server in background on its own.
167 Make ZOOM C recognize option "password". If unset, "pass" is used
168 (for backwards compatibility).
170 Fixed a bug in Generic Frontend Server that could make it crash if a
171 client sets characterSetNegotation bit, but didn't pass negotiation stuff
174 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
175 Must be issued before open, in order to be in effect.
177 --- 2.0.9-6 2004/01/12 Debian/Windows
179 Make the SRU server more picky WRT unknown params, etc.
181 Bug fix: ZOOM scan response didn't return displayTerm - when present.
183 New YAZ client command, options, that sets Z39.50 options.
185 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
186 options from a string of tokens (one token for each option bit).
188 Update SRW diagnostic code messages.
190 --- 2.0.9-5 2004/01/07 Debian/Windows
192 Handle user defined stylesheet for SRW/SRU.
194 --- 2.0.9-4 2004/01/06 Debian/Windows
196 Fix bug in decoding of Content-Length.
198 --- 2.0.9-3 2004/01/06 Debian/Windows
200 Fix a bug with decoding of XML packed records.
202 --- 2.0.9-2 2004/01/05 Debian only
204 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
206 Fix bug in SRW/SRU diagnostics decoding.
210 Fixed bug in Generic Frontend Server which could drop records exceeding
211 preferred message size. Reported and fixed by Irina Dijour.
213 Fixed calculation of package size for structured records in Generic
214 Frontend Server. Reported and fixed by Irina Dijour.
216 Fixed namespace for SRW/SRU diagnostics.
218 Fixed SEGV in yaz-client that occured for HTTP connection errors.
222 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
223 this version is incompatible with version 1.0 and older YAZ SRW/SRU
226 CQL changes to reflect recent changes to the specification:
227 * Documentation talks about context sets instead of index sets.
228 * Documentation talks about indexes instead of qualifiers.
229 * The CQL-to-PQF transformer's configuration file now uses
230 "index.set.name = <attributes>" instead of the old form
231 "qualifier.set.name = <attributes>". (Both forms are still
232 understood but the latter is deprecated.)
233 * CQL terms with no explicit index specified are now interpreted as
234 cql.serverChoice instead of srw.serverChoice (which of course
235 behaves exactly the same.)
239 MARC conversion can now generate ISO2709 output in another
240 character set. yaz-marcdump uses this facility if you invoke it
243 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
244 functions from there can be used from C++.
248 Frontend server now transfers memory from decoded packages to stream
251 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
252 references to show up.
254 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
255 the ZOOM Abstract API. The older names for the same options are still
256 also supported for the benefit of old applications.
258 ZOOM-C supports "implementationId" and "implementationVersion" options
259 to go along with "implementationName". These allow the user code to
260 specify identification strings to be sent to servers.
261 Add OID for the new ExtLite attribute set.
263 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
264 as requested/supplid by Ere Maijala <ere@atp.fi>
266 For generic frontend server, reverse the order of
267 "toolkit-supplied / application-supplied" strings sent as implementationId,
268 Name and Version. Also, remove the spaces around the slash. This brings
269 the GFS in line with the behaviour of ZOOM-C on the client side.
271 Add function ZOOM_scanset_display_term.
273 yaz-client shows scan displayTerm if present.
275 Utility yaz-iconv is now installed by default along with the man page
278 Extend configure check for OpenSSL to use pkg-config where available (such
281 Incorporate patch by Morten Bogeskov which allows a Unix file socket
282 server to specify uid/gid/mask for socket using the format
283 unix:[user=uid,][group=gid,][umask=mask,]file=path
284 If file= is omitted the existing format is assumed, e.g.
286 in which case the mask is 0666 (rw for everybody).
288 Major restructure of YAZ source. All source in libyaz is in src directory.
289 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
290 util (utility programs such as ASN.1 compiler, yaz-marcdump).
292 Added man page for utility yaz-marcdump (used to be called marcdump).
293 yaz-marcdump is installed by 'make install'.
295 Fixed a memory leak in Generic Frontend Server that occurred when decoding
296 of incoming package failed.
298 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
300 Change prototype of odr_perror: add const to message string.
302 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
304 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
305 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
306 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
307 DNS lookup. There should not be any compatibility problems with this
308 assuming that blocking=1 or 0 is used.
310 Fix bad reference in UNIX comstack in function cs_addrstr.
312 Fix for compilation on AIX.
314 The generic front-end server (server/seshigh.c) now supports returning
315 Init diagnostics to the client in User-information-field, in
316 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
321 Allow any CQL relation (not just all,any,exact,scr).
323 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
324 that features the same UI.
326 Implemented command update0 in YAZ client which is equivalent to
327 update but uses old of Ext Update ASN.1.
329 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
330 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
331 Previously no OID was used for this info.
333 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
334 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
335 returns 'malformed search term' otherwise.
337 SortResponse member resultCount now set to NULL in sort handler of
340 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
343 Add three new utility functions for translating OIDs between various
344 formats -- symbolic name such as "Usmarc", minus-1-terminated int
345 arrays and dotted strings such as "1.2.840.10003.9.5.1":
346 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
347 char *oid_to_dotstring(const int *oid, char *oidbuf);
348 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
350 Reverted modifications for ES Update definition for z_IU0Update
351 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
352 is back to YAZ 2.0.2.
354 String value attributes for CCL parser.
356 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
357 which their FirstSearch server returns in Init responses, sometimes
358 carrying useful diagnostic information when Init fails. This has the
359 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
360 "z39.50/oclcui.asn", where its definition is somewhat different from
361 what OCLC document on their web-site, as required to interoperate with
364 Support for anonymous authentication in yaz-client. Use the command
367 * Fix the OID of the Index Data-local "admin" Extended Service from
368 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
369 the 1000, which indicates a locally-defined OID, was a mistake.
373 Fix CCL directive @case handling so that it affects string match for
374 both CCL keywords and qualifiers.
376 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
377 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
378 Decoder has been updated with ASN.1 changes as listed in
379 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
380 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
381 z_IUUpdate, remains unchanged.
383 ZOOM_record_get may now return a record in a specific character set.
384 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
385 "from" is the character set of record as returned by target. "to" is
386 the character set to be returned. If omitted, "to" is UTF-8.
388 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
390 New ODR utility, odr_getelement, which returns name of element for
391 which encoding/decoding failed.
393 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
394 in cases where a required element was omitted.
396 Bug fix: some MARC8 sequences were not converted.
398 New ZOOM option "step" which specifies number of records to be
399 retrieved in one chunk. Used in conjunction with "start" and "count".
401 SRW support for yaz-client. Use scheme http: to use it, e.g.
404 yaz-client no longer does (un)intelligent character set conversions
405 by default. Can be enabled with charset and marc_charset commands.
407 xmalloc trace fix for 64-bit systems such as DEC alpha.
409 Solaris 2.6 compile fix.
411 New function, cql_strerror() translates SRW error codes, as returned
412 by cql_transform_error(), into human-readable English strings. Used
413 in yaz-client diagnostics when appropriate.
415 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
416 converts it into a type-1 query which is sent to the server. This
417 makes CQL available for use with all Z-servers, as opposed to the tiny
418 minority that can handle CQL queries themselves.
422 New Debian package layout similar to the Redhat Package layout.
424 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
425 and search result respectively.
429 Redhat package is now several packages: libyaz (runtime libraries),
430 libyaz-devel (development and documentation, and yaz (utility programs).
431 Package spec file by Morten Bøgeskov.
433 New member 'schema' in struct bend_fetch_rr which the name of requested
434 schema (SRW/SRU) for record (or NULL if none was given). The fetch
435 handler MAY set this to reflect the schema of the returned record.
437 New member 'display_term' in struct scan_entry. GFS now sets member entries
438 and allocates scan entries to be filled by user scan handler. In previous
439 version, entries member was allocated by the scan handler. That still works,
440 but the GFS will ignore member display_term - assuming it was NOT set by
441 the handler. The fact that the GFS now allocates the entries both allows
442 for new members and makes a scan handler easier to write.
444 Fix CQL lex buffer overflow.
446 SRW/SRU recordPacking. For SRW default recordPacking is string. For
447 SRU default recordPacking is string.
449 SRU protocol support for frontend server.
451 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
453 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
455 Added scan for the ZOOM shell (zoomsh).
459 * String Identifers for Schemas (Amendment 5).
460 http://lcweb.loc.gov/z3950/agency/amend/am5.html
461 Old definition for schema
462 Odr_oid *schema; /* OPT */
467 Z_InternationalString *uri;
468 #define Z_Schema_oid 1
469 #define Z_Schema_uri 2
472 * resultCount parameter to Sort Response (Amendment 1).
473 http://lcweb.loc.gov/z3950/agency/amend/am1.html
475 Support for SRW 1.0 over HTTP. This is an optional feature and
476 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
479 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
480 on the same port. SRW SearchRetrieveRequests are mapped
481 to bend_init,bend_search,bend_fetch,bend_close.
483 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
485 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
486 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
488 ZOOM connections are SRW based if schem http is used for hostname
489 in connect, e.g. z = ZOOM_connection_new("http://myserver");
490 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
492 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
493 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
494 distance=n, order=true/false, relation=le, prox unit=word. If
495 n is omitted, distance 1 is used.
497 Fixed problem with C compiler include path in wrong order.
499 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
500 on Solaris. Patch from Ko van der Sloot.
502 New MARC decode API. All new functions operate on a yaz_marc_t
503 handle. The most important new functions are: yaz_marc_create,
504 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
505 decode and destroy respectively. Decoder can produce formats
506 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
507 include/yaz/marcdisp.h.
509 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
510 to UTF-8, UCS-32, wchar_t or Latin-1.
512 * Prototypes for yaz_iconv_-functions moved to separate header
513 include/yaz/yaz-iconv.h.
515 Make a few private functions 'static' in unix.c. This prevents
516 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
518 For ZOOM connection, the options targetImplementation{Id,Name,Version}
519 are set when Init Response is received.
521 New function ZOOM_connection_error_x similar to ZOOM_connection_error
522 but returns diagnostic set as well.
524 New function yaz_strerror which is a portable wrapper for
525 strerror/strerror_r/GetLastMessage.
527 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
528 is returned for MARC. If type is "oai", then OAI MARC is returned.
530 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
535 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
537 Fix bad race conditions on SIGTERM and terminate gracefully in
540 Move retrieval (data1) module to Zebra since nobody seems to be
543 Add GRS-1 render for ZOOM using same format as yaz-client.
547 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
549 Fix broken ESpec handling in data1 module.
551 SGML reader parses comments and makes them part of the data1 tree.
553 Added several type casts so that YAZ compiles as C++ code.
555 ZOOM didn't handle PDU encoding failures properly.
557 Added more Bib-1 diagnostics (approved extensions).
559 GNU configure: better check for iconv.
561 More portable use of accept, getpeername. Check for socklen_t. Use
562 int/size_t if socklen_t is not defined.
566 PQF parser rejects bad queries - including those with extra
567 characters in them. PQF parser used to silently ignore that.
568 Cleaner API for PQF added, which allows you to get detailed
569 error information for bad queries (see yaz/pquery.h).
571 Fixed bug in ZOOM_record_get for type "database".
573 Implemented mini iconv library supporting conversions between
574 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
576 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
580 Fixed ZOOM C record cache so that preferredRecordSyntax and
581 elementSetName is used to check for already fetched records.
585 Added three members in bend_initrequest structure to facilitate
586 character set negotiation.
588 Fixed a bug in frontend server that could cause indefinite
589 loops under rare conditions.
591 Revised character set utilities (charneg.h) so that encoding
592 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
594 For PQF, directive @term <type> sets term type for Scan/Search.
595 Here <type> is general, string, numeric, null. The term type
596 is inherited - just like @attr.
598 New call odr_set_charset that sets character set conversion for
599 international-strings on a ODR stream. Prototype is:
600 int odr_set_charset(ODR o, const char *to, const char *from);
601 The InternationalString is still represented as C string in YAZ
602 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
603 won't). On the protocol level, you can use any encoding.
605 Support for UNIX sockets in ZOOM.
607 Solaris recv sometimes returns errno == ENOENT. It is treated as
608 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
610 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
611 both client and server. Code by Morten Bøgeskov.
615 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
616 that they can be used directly from Visual Basic. You must recompile
617 your windows APP if you're using ZOOM.
619 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
620 Commands "lang" and "charset" sets language and character set respectively.
621 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
622 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
624 Attributes from multiple CCL fields may be OR'ed rather than merged
625 using directive "@field or". Fields are still merged by default -
626 equivalent to "@field merge".
628 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
631 Fixed bug in zget for parameter ExtendedServicesResponse.
637 Added PQF feature: '@attr type=value' may be written as '@type=value'.
639 Client displays USR.1:SearchResult-1 (hits per term).
641 Additional Search Info for search in Generic Frontend Server.
643 Fixed CCL parsing of "field=s".
645 WIN32 installer - using the excellent NSIS software from nullsoft.
647 Fixed CCL parsing of "field = - <number>".
649 Added function yaz_marc_decode that decodes MARC for line mode
650 display or XML (similar to that used by JZKit).
652 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
653 Z39.50. But ISO/ILL was, however.
655 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
656 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
658 http://lcweb.loc.gov/z3950/agency/amend/am2.html
659 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
663 New YAZ client features: Command completion and new commands:
664 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
665 Code provided by Jacob Poulsen.
667 New call oid_trav, that visits all registered OIDs via callback.
669 Function ZOOM_record_get now returns const char pointer rather than
670 void pointer. It saves a lot of type casts.
672 For YAZ client, command "auth" now allows you to set authentication
673 in IdPass style. It is enabled when three tokens are given - order
674 is user, group and password.
676 Fix memory leaks in MARC record handling for ZOOM.
678 New option for YAZ client, -k <kilobytes> that sets
679 maximum record size. Similar to -k option for generic frontend
680 server and yaz-ztest.
682 More fixes for scan. Non-zero stepSize handled. OID's fixes.
684 Prefix query parser reports "fail" when bad attribute set is given.
686 Fix in MARC decoder. Proximity logging. Fix for attribute set
687 in scan handler for server. Patches by Shigeru Ishida.
689 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
692 Configure option --with-openssl=<dir> now works when a directory is
693 specified. Patch provided by Morten Bøgeskov.
695 New option for YAZ client, -u <auth>, that sets authentication.
697 ZOOM fix: error information was sometimes "missing", since error
698 was cleared/reset too when it shouldn't.
700 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
704 Scan for ZOOM API. New object ZOOM_scanset. New functions
705 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
706 ZOOM_scanset_destroy.
708 New ZOOM function, ZOOM_connection_last_event, that returns type
709 of last event (such as "receive data", "send data", "apdu received",
712 New ZOOM option, schema, that specifies schema for retrieval.
714 New CCL feature. Qualifiers can be aliases for one or more
715 other qualifiers (if more than one is given, OR is used).
717 ZOOM uses named result sets if target supports it.
719 Two new YAZ client commands: . (dot, which sources a script of YAZ
720 client commands), and ! (to execute shell command.). Implemented
723 Working on Debian packages.
727 YAZ client enables named result sets only if target supports it.
729 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
731 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
732 with key="host" to get same result.
734 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
735 Function Z3950_resultset_record(s) returns references to records
736 "owned" by resultset. To become owner use Z3950_record_clone.
738 Function z_ext_record handles Extended Services. Thanks to
743 CCL Parser fix: ignore token comma when dealing with and-lists.
745 Documentation updates for COMSTACK.
747 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
748 Changed prototype Z3950_records. For some functions, int parameters
749 were changed to size_t.
751 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
754 New MARC decode/display function, marc_display_exl, which properly rejects
755 non-ISO2709 records. YAZ client uses it.
759 Fix bug: local attribute set wasn't set correctly in PQF strings.
763 * Old Z39.50 codecs no longer supported.
765 Added ZOOM C binding. See http://zoom.z3950.org/
767 Renamed states for COMSTACKs to avoid confusion with events.
769 Implemented cs_look and proper cs_rcvconnect.
771 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
773 Configure detects POSIX threads on OpenBSD.
775 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
776 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
778 When error is returned from present handler, non-surrogate diagnostic
779 is returned in present response (and fetch handler is no longer called).
781 * Minor adjustments to pquery parser (PQF). Token characters may be
782 escaped by using backslash (C-style).
784 PQF parser allows string attribute values to be specified. For @attr,
785 non-numeric characters after the equal-sign are treated as strings
786 (e.g. @attr 9=title).
788 CCL trunction character may be defined (@truncation in file)
790 * function zget_ExtendedServicesRequest sets waitAction to
791 waitIfPossible (was wait).
793 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
796 CCL operator names may be set in field definition files (CCL_bibset).
797 See ccl/bib1 for an example.
799 Fixes in ASN.1 compiler for C++ compatibility.
801 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
802 and "op_or" to avoid conflict with C++.
804 Fixed problem with GNU readline detection on Redhat 7.0.
806 Added step-size for Scan backend handler.
808 Fixed bug that made the frontend server crash when no attribute
809 set was specified for scan.
811 Front-end server automatically switches to original working directory
812 when installed as an NT service. Previously -w had to be specified to
815 Added extended attributes for retrieval module (data1), so that data1
816 records carry d1_readXML/SGML attributes. d1_read also supports
817 null-data rules ( <tag/>)
819 On UNIX when POSIX threads are available, a separate library libyazthread
820 is created. Programmers should link with that library and the yaz library
821 when using threads. The reason for the split was that some applications
822 on Linux, such as Apache, doesn't work well when using shared objects that
825 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
826 (or any frontend server) in SSL mode by specifying ssl: followed by
827 address. Only tested on UNIX.
829 Added feature for CCL module. Virtual structure s=al or s=ol generates
830 and-list and or-list respectively instead of phrase search.
834 * Added prefix "yaz_" for the functions log_init.., log_file.. and
835 log_mask_str. This was done to avoid name conflicts with other libraries
836 (such as other PHP extensions).
838 Added raw OID member for preferred record syntax (request_format_raw)
839 and returned record syntax (output_format_raw) for backend fetch method.
841 Config file yaz-config now accepts options so that it returns specific
842 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
844 Shared library support for UNIX using GNU libtool.
846 * Modified backend interface. Request/Response struct's replaced by
847 one read/write C struct. For example bend_fetchrequest and
848 bend_fetchresult have been replaced by single bend_fetch_rr struct.
849 Every handler - even search has to be registered in bend_init
850 handler. This means that the YAZ library no longer refers to
851 external functions and it makes it possible to make the whole
852 thing a single DLL/SO.
854 Added Segment handler for backend server.
856 Added Zmbol/Zebra administrative functions to YAZ client.
858 Threaded frontend server on UNIX (when POSIX Threads are available).
859 Starting the server with option -T enables multi-threading.
863 Added configure option --enable-comp/disable-comp to control use
864 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
865 located in sub directory asn.
867 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
868 in ${exec_prefix}/bin along with the other programs yaz-client and
871 GNU automake used to maintain makefiles.
875 Changed retrieval module so that we can load records with no abstract
876 syntax defined. Tagpaths in these records are fully composed of string
879 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
883 On UNIX, the generated makefile now supports a proper 'make install'.
884 The prefix can be set via GNU configure to set the install location
885 (default is /usr/local).
887 * YAZ programs client and ztest were renamed to yaz-client and
888 yaz-ztest to avoid conflicts when users install YAZ in "standard"
889 locations, such as /usr/bin,/usr/local/bin,etc.
891 * YAZ Header files were moved from include to include/yaz. YAZ Header
892 files are referred to as include <yaz/log.h> rather than <log.h>.
893 The YAZ include path (-I ..) is therefore the same as before. Programmers
894 should update their #include statements or use -Ipath/include/yaz
895 instead. The main motivation for doing this change is that YAZ header files
896 can be installed in "standard" locations /usr/include,/usr/local/include
897 without introducing conflicts, since ALL YAZ header files are stored
898 in subdirectory yaz (under /usr/include for example).
900 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
901 rather than project/workspace files. We switched because project files
902 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
905 Changed name of logging function, logf, to yaz_log, to prevent name
906 clash with some math-log functions. The YAZ header log.h defines logf
907 to yaz_log (#define) so there should be no incompatibilities by this
910 Added bend_start/bend_stop handlers for server. These handler are
911 called on start/stop of server. For windows they are called whenever
912 a service is started/stopped.
914 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
915 a fairly small ASN.1 compiler written in Tcl. The compiler is located
916 in util/yc.tcl. The auto-generated C code structures are, in a few
917 cases, incompatible with the old decoders. There are differences in the
918 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
919 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
920 The preprocessor variable ASN_COMPILED is defined when the compiled
921 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
922 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
923 wish to use the old encoders/decoders you can specify --disable-yc
926 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
927 version so that it supports both new - and old version of DB Update
929 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
930 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
931 change. The name parameter can be set to 0 in which no name is specified
932 for the construction. The macros odr_implicit and odr_explicit sets name
933 parameter to zero for the construction involved. New macros
934 odr_implicit_tag and odr_explicit_tag are similar to the others,
935 except that a name parameter is added. For programmers' that don't use
936 ODR they probably only need to change the call to z_APDU and z_External.
938 Added access control facility by interfacing the TCP wrapper library.
939 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
940 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
941 name of the daemon and enables the access control as specified in
942 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
944 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
945 den Dool <H.M.vdnDool@kub.nl>.
947 Added reference ID parameter to most functions in server API - refer
948 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
950 Changed name of ccl library to libccl.a (was ccl.a).
952 Fixed bug in decoder for Explain (Category TargetInfo).
954 Added support for GNU readline in client. Thanks to Jacob Poulsen
955 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
957 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
958 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
959 IMPLEMENTATION! This change was made to the development version before
960 the ZIG decided to retract the amendment. If any users MUST be
961 compatible with the original Update definition, PLEASE CONTACT US, and
962 we will include a separate definition corresponding to the old Update
963 ES. Note that because of the change to the ASN.1 of the
964 TaskPackageRecordStructure we cannot define a single structure that
965 will support both versions.
967 * Added const modifier to buffer parameter for some ODR/BER encoding
968 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
969 completeWAIS, odr_dumpBER.
971 Fixed bug in client.c which caused a crash when a scanResponse didn't
972 contain positionOfTerm.
974 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
975 * will cause an error in a client if a non-YAZ target sends both a
976 * list of Scan entries and non-surrogate diagnostics.
978 Retrieval module enhancements. Tag sets may be typed in the reference
979 to it. From the .abs-file the "tagset" directive takes a third optional
980 integer type for the tag set referenced. From a .tag-file the "include"
981 directive takes a third optional type as well. The old "type" directive
982 in the tag set itself is still recognized but acts as the default type
985 Backend interface change. Individual Scan terms returned from bend_scan
986 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
987 in include/backend.h.
989 Retrieval module enhancements. Multiple tag sets and attribute sets may
990 be specified in abstract syntax specs. Revised the error/warning for
991 logging messages reported by the retrieval module when reading the
994 Object Identifier system (oid_..) changed. The API is backwards
995 compatible but the oid-routines now allocates new OID's when needed.
996 Raw OID's may be specified in oid_getvalbyname.
998 YAZ now uses GNU configure to generate Makefile(s).
1000 * Minor changes in some of the member names of DeleteResultSetRequest and
1001 DeleteResultSetResponse. See include/proto.h.
1003 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1004 and added member 'languages' in TargetInfo (which was missing).
1006 Changed the way attribute sets are handled in the retrieval
1007 module. These are now cached, just like the abstract syntaxes
1010 Changed YAZ so that it links with compiled ASN.1.
1012 Added Explain-schema definitions and mapping routines. The following
1013 Explain categories have been implemented: AttributeDetails,
1014 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1016 Fixed minor bug in Windows version of Server Library.
1018 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1020 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1022 Added EXTERNAL: UNIverse Resource Report (non-standard).
1024 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1025 ENUMERATED and SET OF.
1027 * Added 'const' to some of the char pointer arguments for the
1028 functions, data1_read_node, data1_getelementbytagname,
1029 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1032 Fixed bug in data1_insert_taggeddata - the last_child member of
1033 parent wasn't initialised.
1035 * Changed data1_read_record and data1_read_node so that the supplied
1036 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1037 doesn't refer to any parts of the "SGML"-buffer.
1039 Fixed bug in server library (Windows version of statserv_remove).
1041 * Changed code so that it compiles as C++. The type definition
1042 of Odr_fun which is a member of Odr_arm was changed. The result is,
1043 that an explicit typecast is needed for the fun pointer when
1044 using Odr_arm - as in:
1045 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1047 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1049 Implemented the new structured date and time definition as approved
1050 by the ZIG. Added schemaId element to the specificTag in Espec-1
1051 (also approved at the last ZIG). Thanks to RVDM.
1053 Added some Object identifiers (RVDM).
1055 Changed the Update Extended Service (RVDM).
1057 Added command "refid" to client which specifies referenceId for
1058 the following requests.
1060 Implemented extended service handling for server. See ztest.c
1061 for an example as well as backend.h. New handlers are registerd
1062 in the Init handler.
1064 * Changed interface for sort in server.
1066 Added new members to statserv_options_block. It allows a server
1067 to read options from another source than just the command line. Thanks
1068 to Charles Woodfield.
1070 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1071 renamed to zboolean. Some C++ compilers complained about the name.
1073 Minor changes to gils.abs. Added index 's' (sort) on title
1074 and date/time-last-modified.
1076 --- 1.4pl2 1998/1/30
1078 Fixed bug in server library regarding inetd mode (-i). This bug
1079 was introduced by release 1.4.
1081 --- 1.4pl1 1998/1/29
1083 Added sort facility in client and backend server interface.
1085 Fixed problem with dependencies in Makefile(s).
1087 Fixed bugs for encoders/decoders of extended services and
1090 Implemented sub-tree feature for schemas. Sub-trees are
1091 referenced in *.abs-files. See explain.abs for an example
1092 of the use of this feature.
1094 Modified bib1.att; local attributes for ANY didn't include
1095 ANY itself (only affects use of the retrieval module).
1097 Fixed bug in plain SGML reader in function data1_read_node:
1098 tags with prefix "var" was incorrectly interpreted as variants.
1100 Added feature "sub-schemas" to enable references to - and definitions
1101 of - group of elements.
1103 * Removed member parent from type data1_element (in data1.h).
1105 Implemented function odr_nullval() that returns the value of
1108 * Removed member num_children from data1_node (in data1.h).
1110 Made NT service interface part of the server library. The
1111 function statserv_main uses the NT service when required and
1112 calls the statserv_start / statserv_close routines.
1114 Routine zget_SearchRequest and zget_PresentRequest fills
1115 resultSetName/Id member with "default" instead of "Default".
1117 Fixed memory leak in server. Request queue member wasn't freed.
1119 Fixed nmem_exit so that memory is freed.
1123 Revised the CCL parser utility to be thread safe.
1125 Added function, oid_ent_to_oid, to replace the function
1126 oid_getoidbyent, which is not thread safe.
1128 * Added nmem_init and nmem_exit to initialize and release
1129 NMEM resources. Function nmem_init should be called once in the
1130 initial thread before NMEM/ODR is used. statserv.c and client.c
1131 have been changed accordingly. The change was necessary to make
1132 NMEM thread safe. The NMEM memory pool is shared amongst threads
1133 in a process. Unix-based applications will still work fine without
1136 Added NT Services interface for the the Z39.50 (statserv) Server.
1137 Refer to the ztest.c source on the usage.
1139 Windows 95/NT port using MSVC5.0. Project files are included in the
1142 * Defined new 'global' handle for the retrieval (data1) system. The
1143 new handled, data1_handle, describes the state of the data1 system.
1144 This handle is passed as first argument to virtually all
1145 data1 related routines. The functions data1_create and data1_destroy
1146 creates and destroys a data1 handle respectively.
1148 Added ODR encode stream member to all backend request structures
1149 init, search, scan etc. This stream should be used to allocate all
1150 memory used for the response when thread safe operation is needed.
1152 Changed the comstack utility, cs_addstr, to be thread safe. The
1153 returned hostname string returned by the function is now part the
1156 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1157 function. The cs_straddr takes a COMSTACK handle as argument, so this
1158 function must be used after cs_create and before bind/connect.
1159 This function is thread safe.
1161 Moved test server to 'ztest' directory - generic server code still
1162 in 'server' directory.
1164 Made prefix query (pquery.c) utility thread safe.
1166 Added new function modifier YAZ_EXPORT to 'export' public DLL
1167 functions when using windows (see include/yconfig.h).
1169 Added definitions to the OID database (util/oid.c) (RVDM).
1171 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1173 Added call to ccl_rpn_delete in client program.
1175 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1176 release of RPN structure.
1178 Added support for C++, headers uses extern "C" for public definitions.
1179 With input from RVDM.
1181 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1182 Thanks to Ronald van der Meer (RVDM).
1184 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1186 Added support for private extensions to the OID database
1187 (oid_setprivateoids()). Thanks to RVDM.
1189 Added optional, physical ANY (key replication)
1191 Fixed null-reference problem in GRS-1 output filter.
1193 Proximity operator added to Prefix Query Format (PQF).
1195 In test client command "base" accepts multiple databases.
1197 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1201 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1203 Smallish bug-fixes in the new encoders/decoders (explain).
1205 Bug fixed in DeleteRequest.
1207 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1209 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1211 Added SOIF syntax (using private OID for now) to retrieval module and client.
1213 Added Update extended service.
1215 Added SearchResult-1 additional info structure.
1217 Added optional CCL (ISO8777) interpreter as separate module. Available
1220 --- 1.2 1996/6/10 (1st anniversary release)
1222 Added Summary record syntax. Lightly tested.
1224 Added OPAC record syntax. Untested.
1226 Added ResourceReport service encoders/decoders. Untested.
1228 Fixed bug in z_Unit - wrong tagging on unitSystem.
1230 Fixed bug in the DiagRecs decoder.
1232 Added options for max PDU size and session timeout to frontend-server.
1234 Added documentation of query-language parsers and other supporting utilities.
1236 [frontend-server] Added Attribute set to the bend_scanrequest API.
1238 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1239 surrogate diagnostics were generated.
1241 [retrieval] Allow multiple local values for attribute.
1243 [retrieval] Allow multiple attributes per element in .abs files. index type.
1245 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1247 --- 1.1pl2 1996/4/10
1249 Minor changes, mostly specific to Zebra's requirements (retrieval)
1253 Repaired bug in frontend server when running multiple listening
1254 endpoints in dynamic mode.
1256 z_External() now won't break if a known, ASN.1 value comes encapsulated
1257 in an octet-string. The value will pass through unmodified in an Odr_oct.
1259 Added a bit of code to the demo client to decode & display
1260 ASN.1-structured records represented in the octet-aligned branch of
1261 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1263 Added z_ext_getentbyref() to the ASN module. Doc updated.
1265 * Completed the SCAN definition in the ASN module. This may break SCAN
1266 code based on older YAZ-versions at compile-time. The fix is easy -
1269 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1270 under the SCAN definition. Remember to initialize this, server-people.
1272 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1273 that this does not extend to ODR and ASN.
1275 Comstack allows insertion of established socket (primarily for
1276 inetd-operation of servers). Doc updated.
1278 Front-end server can now start from the inetd in TCP mode. Doc
1281 --- 1.0pl4 1996/1/24
1285 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1286 the rank and record number.
1288 Adjustments to the frontend server.
1290 Fixed diagnostic BER dumper. It ignored the file argument.
1294 Various changes to retrieval module.
1296 Changed the union discriminators of the protocol files from enums to
1297 ints paired with #defines.
1299 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1302 *Changed operator in the RPN structure to 'roperator', again to avoid a
1305 Fixed problems in Explain decoders/encoders.
1307 --- 1.0pl2 1995/12/6
1309 Memory bug in log module fixed.
1311 --- 1.0pl1 1995/12/5
1313 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1315 Bug in Explain DatabaseInfo module fixed.
1317 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1321 The shift to v1.0 signals that we now consider the *core* functionality
1322 of YAZ reasonably stable (the core being more or less equivalent to
1323 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1324 tested (Explain not at all - though that will happen soonish).
1326 Minor changes to code to support Windows port.
1328 Various minor changes after we're getting to use GRS-1 & co. more.
1330 Added Espec-1 format.
1332 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1333 of the protocol and it cannot be selected when encoding (maps into 'string'
1334 when decoding). Needed to talk to some servers.
1336 Demo client can request simple element set names.
1338 Added Diagnostic Format encoders/decoders.
1340 Added simple Close handling to frontend server (no hooks for resource
1341 reporting yet), and demonstration client.
1343 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1345 --- 1.0b3 1995/08/24
1347 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1348 handled incorrectly when records were requested in the searchResponse. This
1349 will only affect you if you use the frontend-server.
1351 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1352 Test-client will ask for and print GRS1. Ztest will return dummy records
1355 Added Explain encoders/decoders to the service-level API. Untested.
1357 Added Extended Services: Item Order encoders and decoders to the Service-
1358 level API. Untested. We could use a recent copy of the pertinent bits
1359 of the ILL protocol to add those bits.
1361 Added diagnostic format 1 encoders/decoders to the service-level API.
1364 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1365 odr_cons.c, which causes a more correct output.
1367 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1368 was always set to 0 when no records were requested in the searchRequest.
1370 * Added better external-handling. This shouldn't harm old code that
1371 *encodes* externals. It can break code that looks for a
1372 'single-ASN1-type' representation, since those types that are known
1373 are now decoded immediately. Look at the SUTRS sample code in
1374 seshigh.c and client.c. Documentation updated.
1376 Handling of structured records in bend_fetchresponse. Length -1 marks
1377 structured record, type is deduced from format field.
1379 --- 1.0b2 1995/06/27
1380 Fairly quick maintenance release to add SUTRS support.
1382 Fixed handling of SUTRS records in the demonstration client.
1384 * Added format field to the bend_fetchrequest and bend_fetchresponce
1385 structures of the backend API (frontend server). When the record is
1386 returned, the value of the format field is mapped to an OID. The
1387 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1388 of the record. The special value VAL_NONE in the bend_request means
1389 that no specific format was requested by the client. Documentation
1390 updated accordingly. Test server (ztest) will return a fixed dummy
1391 SUTRS record if your client requests SUTRS.
1393 Documentation updated accordingly.
1395 You can now set external libraries and RANLIB support in the top-level
1399 First public release.
