1 Possible compatibility problems with earlier versions marked with '*'.
5 Added yaz_log_time_format which specifies log format using
8 Added yaz_log_module_level which returns mask for a module. Value
9 is non-zero mask a if module is enabled; zero if disabled.
11 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
14 Fixed bug #176: Dont throw diagnostics on empty SRU args.
16 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
18 Fixed bug #172: RPM builds does not enable SSL.
20 Doxyfile.in part of dist. Doxyfile generated by configure.
22 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
23 are given and the corresponding component does not exist.
25 Extend CCL documentation in YAZ reference. Describe r=r.
29 Fixed MARC->MARCXML conversion to properly deal with
30 fields, subfields, indicators having non-ASCII characters.
32 Fixed MARC->MARCXML conversion so that ASCII control characters
33 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
36 Added YAZ GFS support for conversion from Z39.50 surrogate
37 diagnostics to SRW surrogate diagnostics.
39 Bug fix: YAZ GFS did not return schema in explainResponse.
43 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
44 now converts recordSchema to elementSetName as well as schema URI.
46 Fixed bug in COMSTACK that prevented HTTP request packages from being
51 Added CCL facility r=r "range" which is similar to r=o "ordered" but
52 does not require white-space before and after the dash in a range, e.g.
53 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
56 Fixed a few AC_TRY_LINK configure tests that did not operate properly
57 due to new GCC removing "redundant" code.
59 Added yaz-client commands scanpos and scanstep that sets preferred
60 position and step-size for scan.
62 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
64 Added CCL utility ccl_qual_buf which parses one or more CCL
65 spec lines in a buffer.
67 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
68 of name and value - ignoring empty lines and comments.
70 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
72 Added odr_get_element_path which returns current element path for an
73 ODR handle. This utility is useful in error handling or user-defined
76 Added ODR_PRINT utility odr_set_stream which is is a more generic
77 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
78 to a write function and pointer to close function. The close function - if
79 non-NULL - will be called during odr_destroy.
81 Fixed bug in CCL parser where truncation char was not removed from
82 right side when truncation=both was in effect.
84 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
89 Fix buffer overrun in CQL parser when dealing with proximity (%).
91 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
92 to UTF-8/UCS conversion is now only based on codetables.xml.
94 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
98 Add support for more "commit changes" in ZOOM (uses Extended Services).
100 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
103 Yet another small fix for configure of SSL.
105 --- 2.0.21 2004/05/14
107 Fix SSL libs for configure when --with-openssl=DIR is given.
109 --- 2.0.20 2004/05/10
111 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
113 SSL comstack now uses yaz.pem certificate file on server side
114 by default. Certificate filename can be configured by calling
115 comstack function cs_set_ssl_certificate_file before cs_bind is used.
117 Fix bug regarding multiple calls to ZOOM_connection_connect.
119 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
121 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
122 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
124 ZOOM now allows inspection of X509 peer certificate for verification.
125 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
127 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
128 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
129 as "modular" but it simplifies things.
131 Added cs_get_peer_certificate to that returns peer X509 PEM.
133 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
134 NULL if SSL is unavailable.
136 Documentation about MARC decoding tools.
138 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
140 --- 2.0.19 2004/03/30
142 Rename CHANGELOG to NEWS to follow GNU style packing.
144 Fix bug with missing initialization of member in init_diagnostics.
145 This bug affects threaded version of GFS server.
147 --- 2.0.18 2004/03/20
149 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
152 Ensure zlib.dll is packed with Windows install.
154 --- 2.0.17 2004/03/17
156 Fix encoding of xsd:string to use text instead of CDATA.
158 Fix endless loop in CQL parser with unbalanced ".
160 Use a more compact way to store MARC-8 conversion tables.
162 --- 2.0.16 2004/03/16 Debian only
164 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
167 Update CQL parser to use new CQL 1.1 modifiers for booleans and
172 --- 2.0.15 2004/03/01
174 Another fix for decoding of XML packed records.
176 --- 2.0.14 2004/02/25
178 Fixes for Chunked encoding. White space not ignored after length spec.
180 Update NS and use default NS for SRW diagnostic elements.
182 --- 2.0.13 2004/02/23
184 Implement ZOOM_resultset_cache_reset which resets record cache.
186 Implement ZOOM_resultset_sort which sorts a result set.
188 Implement chunked HTTP transfer.
190 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
192 --- 2.0.12 2004/02/16
194 Added member 'schema' to bend_explain_rr structure so that backend
195 can specify explain record identifier. Defaults to Zeerex 2.0.
197 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
199 --- 2.0.11 2004/02/16
201 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
204 Added init command for yaz-client which sends "extra" init request.
206 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
207 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
209 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
211 Make ZOOM error code for "invalid query".
213 Fixed compilation for SSL which wasn't properly enabled for all platforms.
215 --- 2.0.10 2004/02/05
217 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
220 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
222 Added option -p <file> to make Generic Frontend Server to write PID file.
224 Added option -D to put Generic Frontend Server in background on its own.
226 Make ZOOM C recognize option "password". If unset, "pass" is used
227 (for backwards compatibility).
229 Fixed a bug in Generic Frontend Server that could make it crash if a
230 client sets characterSetNegotation bit, but didn't pass negotiation stuff
233 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
234 Must be issued before open, in order to be in effect.
236 --- 2.0.9-6 2004/01/12 Debian/Windows
238 Make the SRU server more picky WRT unknown params, etc.
240 Bug fix: ZOOM scan response didn't return displayTerm - when present.
242 New YAZ client command, options, that sets Z39.50 options.
244 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
245 options from a string of tokens (one token for each option bit).
247 Update SRW diagnostic code messages.
249 --- 2.0.9-5 2004/01/07 Debian/Windows
251 Handle user defined stylesheet for SRW/SRU.
253 --- 2.0.9-4 2004/01/06 Debian/Windows
255 Fix bug in decoding of Content-Length.
257 --- 2.0.9-3 2004/01/06 Debian/Windows
259 Fix a bug with decoding of XML packed records.
261 --- 2.0.9-2 2004/01/05 Debian only
263 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
265 Fix bug in SRW/SRU diagnostics decoding.
269 Fixed bug in Generic Frontend Server which could drop records exceeding
270 preferred message size. Reported and fixed by Irina Dijour.
272 Fixed calculation of package size for structured records in Generic
273 Frontend Server. Reported and fixed by Irina Dijour.
275 Fixed namespace for SRW/SRU diagnostics.
277 Fixed SEGV in yaz-client that occured for HTTP connection errors.
281 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
282 this version is incompatible with version 1.0 and older YAZ SRW/SRU
285 CQL changes to reflect recent changes to the specification:
286 * Documentation talks about context sets instead of index sets.
287 * Documentation talks about indexes instead of qualifiers.
288 * The CQL-to-PQF transformer's configuration file now uses
289 "index.set.name = <attributes>" instead of the old form
290 "qualifier.set.name = <attributes>". (Both forms are still
291 understood but the latter is deprecated.)
292 * CQL terms with no explicit index specified are now interpreted as
293 cql.serverChoice instead of srw.serverChoice (which of course
294 behaves exactly the same.)
298 MARC conversion can now generate ISO2709 output in another
299 character set. yaz-marcdump uses this facility if you invoke it
302 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
303 functions from there can be used from C++.
307 Frontend server now transfers memory from decoded packages to stream
310 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
311 references to show up.
313 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
314 the ZOOM Abstract API. The older names for the same options are still
315 also supported for the benefit of old applications.
317 ZOOM-C supports "implementationId" and "implementationVersion" options
318 to go along with "implementationName". These allow the user code to
319 specify identification strings to be sent to servers.
320 Add OID for the new ExtLite attribute set.
322 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
323 as requested/supplid by Ere Maijala <ere@atp.fi>
325 For generic frontend server, reverse the order of
326 "toolkit-supplied / application-supplied" strings sent as implementationId,
327 Name and Version. Also, remove the spaces around the slash. This brings
328 the GFS in line with the behaviour of ZOOM-C on the client side.
330 Add function ZOOM_scanset_display_term.
332 yaz-client shows scan displayTerm if present.
334 Utility yaz-iconv is now installed by default along with the man page
337 Extend configure check for OpenSSL to use pkg-config where available (such
340 Incorporate patch by Morten Bogeskov which allows a Unix file socket
341 server to specify uid/gid/mask for socket using the format
342 unix:[user=uid,][group=gid,][umask=mask,]file=path
343 If file= is omitted the existing format is assumed, e.g.
345 in which case the mask is 0666 (rw for everybody).
347 Major restructure of YAZ source. All source in libyaz is in src directory.
348 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
349 util (utility programs such as ASN.1 compiler, yaz-marcdump).
351 Added man page for utility yaz-marcdump (used to be called marcdump).
352 yaz-marcdump is installed by 'make install'.
354 Fixed a memory leak in Generic Frontend Server that occurred when decoding
355 of incoming package failed.
357 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
359 Change prototype of odr_perror: add const to message string.
361 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
363 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
364 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
365 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
366 DNS lookup. There should not be any compatibility problems with this
367 assuming that blocking=1 or 0 is used.
369 Fix bad reference in UNIX comstack in function cs_addrstr.
371 Fix for compilation on AIX.
373 The generic front-end server (server/seshigh.c) now supports returning
374 Init diagnostics to the client in User-information-field, in
375 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
380 Allow any CQL relation (not just all,any,exact,scr).
382 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
383 that features the same UI.
385 Implemented command update0 in YAZ client which is equivalent to
386 update but uses old of Ext Update ASN.1.
388 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
389 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
390 Previously no OID was used for this info.
392 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
393 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
394 returns 'malformed search term' otherwise.
396 SortResponse member resultCount now set to NULL in sort handler of
399 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
402 Add three new utility functions for translating OIDs between various
403 formats -- symbolic name such as "Usmarc", minus-1-terminated int
404 arrays and dotted strings such as "1.2.840.10003.9.5.1":
405 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
406 char *oid_to_dotstring(const int *oid, char *oidbuf);
407 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
409 Reverted modifications for ES Update definition for z_IU0Update
410 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
411 is back to YAZ 2.0.2.
413 String value attributes for CCL parser.
415 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
416 which their FirstSearch server returns in Init responses, sometimes
417 carrying useful diagnostic information when Init fails. This has the
418 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
419 "z39.50/oclcui.asn", where its definition is somewhat different from
420 what OCLC document on their web-site, as required to interoperate with
423 Support for anonymous authentication in yaz-client. Use the command
426 * Fix the OID of the Index Data-local "admin" Extended Service from
427 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
428 the 1000, which indicates a locally-defined OID, was a mistake.
432 Fix CCL directive @case handling so that it affects string match for
433 both CCL keywords and qualifiers.
435 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
436 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
437 Decoder has been updated with ASN.1 changes as listed in
438 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
439 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
440 z_IUUpdate, remains unchanged.
442 ZOOM_record_get may now return a record in a specific character set.
443 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
444 "from" is the character set of record as returned by target. "to" is
445 the character set to be returned. If omitted, "to" is UTF-8.
447 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
449 New ODR utility, odr_getelement, which returns name of element for
450 which encoding/decoding failed.
452 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
453 in cases where a required element was omitted.
455 Bug fix: some MARC8 sequences were not converted.
457 New ZOOM option "step" which specifies number of records to be
458 retrieved in one chunk. Used in conjunction with "start" and "count".
460 SRW support for yaz-client. Use scheme http: to use it, e.g.
463 yaz-client no longer does (un)intelligent character set conversions
464 by default. Can be enabled with charset and marc_charset commands.
466 xmalloc trace fix for 64-bit systems such as DEC alpha.
468 Solaris 2.6 compile fix.
470 New function, cql_strerror() translates SRW error codes, as returned
471 by cql_transform_error(), into human-readable English strings. Used
472 in yaz-client diagnostics when appropriate.
474 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
475 converts it into a type-1 query which is sent to the server. This
476 makes CQL available for use with all Z-servers, as opposed to the tiny
477 minority that can handle CQL queries themselves.
481 New Debian package layout similar to the Redhat Package layout.
483 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
484 and search result respectively.
488 Redhat package is now several packages: libyaz (runtime libraries),
489 libyaz-devel (development and documentation, and yaz (utility programs).
490 Package spec file by Morten Bøgeskov.
492 New member 'schema' in struct bend_fetch_rr which the name of requested
493 schema (SRW/SRU) for record (or NULL if none was given). The fetch
494 handler MAY set this to reflect the schema of the returned record.
496 New member 'display_term' in struct scan_entry. GFS now sets member entries
497 and allocates scan entries to be filled by user scan handler. In previous
498 version, entries member was allocated by the scan handler. That still works,
499 but the GFS will ignore member display_term - assuming it was NOT set by
500 the handler. The fact that the GFS now allocates the entries both allows
501 for new members and makes a scan handler easier to write.
503 Fix CQL lex buffer overflow.
505 SRW/SRU recordPacking. For SRW default recordPacking is string. For
506 SRU default recordPacking is string.
508 SRU protocol support for frontend server.
510 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
512 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
514 Added scan for the ZOOM shell (zoomsh).
518 * String Identifers for Schemas (Amendment 5).
519 http://lcweb.loc.gov/z3950/agency/amend/am5.html
520 Old definition for schema
521 Odr_oid *schema; /* OPT */
526 Z_InternationalString *uri;
527 #define Z_Schema_oid 1
528 #define Z_Schema_uri 2
531 * resultCount parameter to Sort Response (Amendment 1).
532 http://lcweb.loc.gov/z3950/agency/amend/am1.html
534 Support for SRW 1.0 over HTTP. This is an optional feature and
535 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
538 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
539 on the same port. SRW SearchRetrieveRequests are mapped
540 to bend_init,bend_search,bend_fetch,bend_close.
542 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
544 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
545 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
547 ZOOM connections are SRW based if schem http is used for hostname
548 in connect, e.g. z = ZOOM_connection_new("http://myserver");
549 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
551 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
552 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
553 distance=n, order=true/false, relation=le, prox unit=word. If
554 n is omitted, distance 1 is used.
556 Fixed problem with C compiler include path in wrong order.
558 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
559 on Solaris. Patch from Ko van der Sloot.
561 New MARC decode API. All new functions operate on a yaz_marc_t
562 handle. The most important new functions are: yaz_marc_create,
563 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
564 decode and destroy respectively. Decoder can produce formats
565 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
566 include/yaz/marcdisp.h.
568 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
569 to UTF-8, UCS-32, wchar_t or Latin-1.
571 * Prototypes for yaz_iconv_-functions moved to separate header
572 include/yaz/yaz-iconv.h.
574 Make a few private functions 'static' in unix.c. This prevents
575 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
577 For ZOOM connection, the options targetImplementation{Id,Name,Version}
578 are set when Init Response is received.
580 New function ZOOM_connection_error_x similar to ZOOM_connection_error
581 but returns diagnostic set as well.
583 New function yaz_strerror which is a portable wrapper for
584 strerror/strerror_r/GetLastMessage.
586 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
587 is returned for MARC. If type is "oai", then OAI MARC is returned.
589 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
594 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
596 Fix bad race conditions on SIGTERM and terminate gracefully in
599 Move retrieval (data1) module to Zebra since nobody seems to be
602 Add GRS-1 render for ZOOM using same format as yaz-client.
606 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
608 Fix broken ESpec handling in data1 module.
610 SGML reader parses comments and makes them part of the data1 tree.
612 Added several type casts so that YAZ compiles as C++ code.
614 ZOOM didn't handle PDU encoding failures properly.
616 Added more Bib-1 diagnostics (approved extensions).
618 GNU configure: better check for iconv.
620 More portable use of accept, getpeername. Check for socklen_t. Use
621 int/size_t if socklen_t is not defined.
625 PQF parser rejects bad queries - including those with extra
626 characters in them. PQF parser used to silently ignore that.
627 Cleaner API for PQF added, which allows you to get detailed
628 error information for bad queries (see yaz/pquery.h).
630 Fixed bug in ZOOM_record_get for type "database".
632 Implemented mini iconv library supporting conversions between
633 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
635 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
639 Fixed ZOOM C record cache so that preferredRecordSyntax and
640 elementSetName is used to check for already fetched records.
644 Added three members in bend_initrequest structure to facilitate
645 character set negotiation.
647 Fixed a bug in frontend server that could cause indefinite
648 loops under rare conditions.
650 Revised character set utilities (charneg.h) so that encoding
651 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
653 For PQF, directive @term <type> sets term type for Scan/Search.
654 Here <type> is general, string, numeric, null. The term type
655 is inherited - just like @attr.
657 New call odr_set_charset that sets character set conversion for
658 international-strings on a ODR stream. Prototype is:
659 int odr_set_charset(ODR o, const char *to, const char *from);
660 The InternationalString is still represented as C string in YAZ
661 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
662 won't). On the protocol level, you can use any encoding.
664 Support for UNIX sockets in ZOOM.
666 Solaris recv sometimes returns errno == ENOENT. It is treated as
667 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
669 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
670 both client and server. Code by Morten Bøgeskov.
674 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
675 that they can be used directly from Visual Basic. You must recompile
676 your windows APP if you're using ZOOM.
678 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
679 Commands "lang" and "charset" sets language and character set respectively.
680 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
681 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
683 Attributes from multiple CCL fields may be OR'ed rather than merged
684 using directive "@field or". Fields are still merged by default -
685 equivalent to "@field merge".
687 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
690 Fixed bug in zget for parameter ExtendedServicesResponse.
696 Added PQF feature: '@attr type=value' may be written as '@type=value'.
698 Client displays USR.1:SearchResult-1 (hits per term).
700 Additional Search Info for search in Generic Frontend Server.
702 Fixed CCL parsing of "field=s".
704 WIN32 installer - using the excellent NSIS software from nullsoft.
706 Fixed CCL parsing of "field = - <number>".
708 Added function yaz_marc_decode that decodes MARC for line mode
709 display or XML (similar to that used by JZKit).
711 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
712 Z39.50. But ISO/ILL was, however.
714 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
715 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

722 New YAZ client features: Command completion and new commands:
723 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
724 Code provided by Jacob Poulsen.
726 New call oid_trav, that visits all registered OIDs via callback.
728 Function ZOOM_record_get now returns const char pointer rather than
729 void pointer. It saves a lot of type casts.
731 For YAZ client, command "auth" now allows you to set authentication
732 in IdPass style. It is enabled when three tokens are given - order
733 is user, group and password.
735 Fix memory leaks in MARC record handling for ZOOM.
737 New option for YAZ client, -k <kilobytes> that sets
738 maximum record size. Similar to -k option for generic frontend
739 server and yaz-ztest.
741 More fixes for scan. Non-zero stepSize handled. OID's fixes.
743 Prefix query parser reports "fail" when bad attribute set is given.
745 Fix in MARC decoder. Proximity logging. Fix for attribute set
746 in scan handler for server. Patches by Shigeru Ishida.
748 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
751 Configure option --with-openssl=<dir> now works when a directory is
752 specified. Patch provided by Morten Bøgeskov.
754 New option for YAZ client, -u <auth>, that sets authentication.
756 ZOOM fix: error information was sometimes "missing", since error
757 was cleared/reset too when it shouldn't.
759 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
763 Scan for ZOOM API. New object ZOOM_scanset. New functions
764 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
765 ZOOM_scanset_destroy.
767 New ZOOM function, ZOOM_connection_last_event, that returns type
768 of last event (such as "receive data", "send data", "apdu received",
771 New ZOOM option, schema, that specifies schema for retrieval.
773 New CCL feature. Qualifiers can be aliases for one or more
774 other qualifiers (if more than one is given, OR is used).
776 ZOOM uses named result sets if target supports it.
778 Two new YAZ client commands: . (dot, which sources a script of YAZ
779 client commands), and ! (to execute shell command.). Implemented
782 Working on Debian packages.
786 YAZ client enables named result sets only if target supports it.
788 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
790 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
791 with key="host" to get same result.
793 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
794 Function Z3950_resultset_record(s) returns references to records
795 "owned" by resultset. To become owner use Z3950_record_clone.
797 Function z_ext_record handles Extended Services. Thanks to
802 CCL Parser fix: ignore token comma when dealing with and-lists.
804 Documentation updates for COMSTACK.
806 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
807 Changed prototype Z3950_records. For some functions, int parameters
808 were changed to size_t.
810 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
813 New MARC decode/display function, marc_display_exl, which properly rejects
814 non-ISO2709 records. YAZ client uses it.
818 Fix bug: local attribute set wasn't set correctly in PQF strings.
822 * Old Z39.50 codecs no longer supported.
824 Added ZOOM C binding. See http://zoom.z3950.org/
826 Renamed states for COMSTACKs to avoid confusion with events.
828 Implemented cs_look and proper cs_rcvconnect.
830 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
832 Configure detects POSIX threads on OpenBSD.
834 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
835 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
837 When error is returned from present handler, non-surrogate diagnostic
838 is returned in present response (and fetch handler is no longer called).
840 * Minor adjustments to pquery parser (PQF). Token characters may be
841 escaped by using backslash (C-style).
843 PQF parser allows string attribute values to be specified. For @attr,
844 non-numeric characters after the equal-sign are treated as strings
845 (e.g. @attr 9=title).
847 CCL trunction character may be defined (@truncation in file)
849 * function zget_ExtendedServicesRequest sets waitAction to
850 waitIfPossible (was wait).
852 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
855 CCL operator names may be set in field definition files (CCL_bibset).
856 See ccl/bib1 for an example.
858 Fixes in ASN.1 compiler for C++ compatibility.
860 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
861 and "op_or" to avoid conflict with C++.
863 Fixed problem with GNU readline detection on Redhat 7.0.
865 Added step-size for Scan backend handler.
867 Fixed bug that made the frontend server crash when no attribute
868 set was specified for scan.
870 Front-end server automatically switches to original working directory
871 when installed as an NT service. Previously -w had to be specified to
874 Added extended attributes for retrieval module (data1), so that data1
875 records carry d1_readXML/SGML attributes. d1_read also supports
876 null-data rules ( <tag/>)
878 On UNIX when POSIX threads are available, a separate library libyazthread
879 is created. Programmers should link with that library and the yaz library
880 when using threads. The reason for the split was that some applications
881 on Linux, such as Apache, doesn't work well when using shared objects that
884 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
885 (or any frontend server) in SSL mode by specifying ssl: followed by
886 address. Only tested on UNIX.
888 Added feature for CCL module. Virtual structure s=al or s=ol generates
889 and-list and or-list respectively instead of phrase search.
893 * Added prefix "yaz_" for the functions log_init.., log_file.. and
894 log_mask_str. This was done to avoid name conflicts with other libraries
895 (such as other PHP extensions).
897 Added raw OID member for preferred record syntax (request_format_raw)
898 and returned record syntax (output_format_raw) for backend fetch method.
900 Config file yaz-config now accepts options so that it returns specific
901 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
903 Shared library support for UNIX using GNU libtool.
905 * Modified backend interface. Request/Response struct's replaced by
906 one read/write C struct. For example bend_fetchrequest and
907 bend_fetchresult have been replaced by single bend_fetch_rr struct.
908 Every handler - even search has to be registered in bend_init
909 handler. This means that the YAZ library no longer refers to
910 external functions and it makes it possible to make the whole
911 thing a single DLL/SO.
913 Added Segment handler for backend server.
915 Added Zmbol/Zebra administrative functions to YAZ client.
917 Threaded frontend server on UNIX (when POSIX Threads are available).
918 Starting the server with option -T enables multi-threading.
922 Added configure option --enable-comp/disable-comp to control use
923 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
924 located in sub directory asn.
926 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
927 in ${exec_prefix}/bin along with the other programs yaz-client and
930 GNU automake used to maintain makefiles.
934 Changed retrieval module so that we can load records with no abstract
935 syntax defined. Tagpaths in these records are fully composed of string
938 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
942 On UNIX, the generated makefile now supports a proper 'make install'.
943 The prefix can be set via GNU configure to set the install location
944 (default is /usr/local).
946 * YAZ programs client and ztest were renamed to yaz-client and
947 yaz-ztest to avoid conflicts when users install YAZ in "standard"
948 locations, such as /usr/bin,/usr/local/bin,etc.
950 * YAZ Header files were moved from include to include/yaz. YAZ Header
951 files are referred to as include <yaz/log.h> rather than <log.h>.
952 The YAZ include path (-I ..) is therefore the same as before. Programmers
953 should update their #include statements or use -Ipath/include/yaz
954 instead. The main motivation for doing this change is that YAZ header files
955 can be installed in "standard" locations /usr/include,/usr/local/include
956 without introducing conflicts, since ALL YAZ header files are stored
957 in subdirectory yaz (under /usr/include for example).
959 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
960 rather than project/workspace files. We switched because project files
961 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
964 Changed name of logging function, logf, to yaz_log, to prevent name
965 clash with some math-log functions. The YAZ header log.h defines logf
966 to yaz_log (#define) so there should be no incompatibilities by this
969 Added bend_start/bend_stop handlers for server. These handler are
970 called on start/stop of server. For windows they are called whenever
971 a service is started/stopped.
973 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
974 a fairly small ASN.1 compiler written in Tcl. The compiler is located
975 in util/yc.tcl. The auto-generated C code structures are, in a few
976 cases, incompatible with the old decoders. There are differences in the
977 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
978 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
979 The preprocessor variable ASN_COMPILED is defined when the compiled
980 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
981 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
982 wish to use the old encoders/decoders you can specify --disable-yc
985 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
986 version so that it supports both new - and old version of DB Update
988 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
989 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
990 change. The name parameter can be set to 0 in which no name is specified
991 for the construction. The macros odr_implicit and odr_explicit sets name
992 parameter to zero for the construction involved. New macros
993 odr_implicit_tag and odr_explicit_tag are similar to the others,
994 except that a name parameter is added. For programmers' that don't use
995 ODR they probably only need to change the call to z_APDU and z_External.
997 Added access control facility by interfacing the TCP wrapper library.
998 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
999 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1000 name of the daemon and enables the access control as specified in
1001 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1003 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1004 den Dool <H.M.vdnDool@kub.nl>.
1006 Added reference ID parameter to most functions in server API - refer
1007 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1009 Changed name of ccl library to libccl.a (was ccl.a).
1011 Fixed bug in decoder for Explain (Category TargetInfo).
1013 Added support for GNU readline in client. Thanks to Jacob Poulsen
1014 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1016 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1017 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1018 IMPLEMENTATION! This change was made to the development version before
1019 the ZIG decided to retract the amendment. If any users MUST be
1020 compatible with the original Update definition, PLEASE CONTACT US, and
1021 we will include a separate definition corresponding to the old Update
1022 ES. Note that because of the change to the ASN.1 of the
1023 TaskPackageRecordStructure we cannot define a single structure that
1024 will support both versions.
1026 * Added const modifier to buffer parameter for some ODR/BER encoding
1027 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1028 completeWAIS, odr_dumpBER.
1030 Fixed bug in client.c which caused a crash when a scanResponse didn't
1031 contain positionOfTerm.
1033 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1034 * will cause an error in a client if a non-YAZ target sends both a
1035 * list of Scan entries and non-surrogate diagnostics.
1037 Retrieval module enhancements. Tag sets may be typed in the reference
1038 to it. From the .abs-file the "tagset" directive takes a third optional
1039 integer type for the tag set referenced. From a .tag-file the "include"
1040 directive takes a third optional type as well. The old "type" directive
1041 in the tag set itself is still recognized but acts as the default type
1044 Backend interface change. Individual Scan terms returned from bend_scan
1045 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1046 in include/backend.h.
1048 Retrieval module enhancements. Multiple tag sets and attribute sets may
1049 be specified in abstract syntax specs. Revised the error/warning for
1050 logging messages reported by the retrieval module when reading the
1053 Object Identifier system (oid_..) changed. The API is backwards
1054 compatible but the oid-routines now allocates new OID's when needed.
1055 Raw OID's may be specified in oid_getvalbyname.
1057 YAZ now uses GNU configure to generate Makefile(s).
1059 * Minor changes in some of the member names of DeleteResultSetRequest and
1060 DeleteResultSetResponse. See include/proto.h.
1062 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1063 and added member 'languages' in TargetInfo (which was missing).
1065 Changed the way attribute sets are handled in the retrieval
1066 module. These are now cached, just like the abstract syntaxes
1069 Changed YAZ so that it links with compiled ASN.1.
1071 Added Explain-schema definitions and mapping routines. The following
1072 Explain categories have been implemented: AttributeDetails,
1073 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1075 Fixed minor bug in Windows version of Server Library.
1077 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1079 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1081 Added EXTERNAL: UNIverse Resource Report (non-standard).
1083 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1084 ENUMERATED and SET OF.
1086 * Added 'const' to some of the char pointer arguments for the
1087 functions, data1_read_node, data1_getelementbytagname,
1088 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1091 Fixed bug in data1_insert_taggeddata - the last_child member of
1092 parent wasn't initialised.
1094 * Changed data1_read_record and data1_read_node so that the supplied
1095 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1096 doesn't refer to any parts of the "SGML"-buffer.
1098 Fixed bug in server library (Windows version of statserv_remove).
1100 * Changed code so that it compiles as C++. The type definition
1101 of Odr_fun which is a member of Odr_arm was changed. The result is,
1102 that an explicit typecast is needed for the fun pointer when
1103 using Odr_arm - as in:
1104 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1106 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1108 Implemented the new structured date and time definition as approved
1109 by the ZIG. Added schemaId element to the specificTag in Espec-1
1110 (also approved at the last ZIG). Thanks to RVDM.
1112 Added some Object identifiers (RVDM).
1114 Changed the Update Extended Service (RVDM).
1116 Added command "refid" to client which specifies referenceId for
1117 the following requests.
1119 Implemented extended service handling for server. See ztest.c
1120 for an example as well as backend.h. New handlers are registerd
1121 in the Init handler.
1123 * Changed interface for sort in server.
1125 Added new members to statserv_options_block. It allows a server
1126 to read options from another source than just the command line. Thanks
1127 to Charles Woodfield.
1129 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1130 renamed to zboolean. Some C++ compilers complained about the name.
1132 Minor changes to gils.abs. Added index 's' (sort) on title
1133 and date/time-last-modified.
1135 --- 1.4pl2 1998/1/30
1137 Fixed bug in server library regarding inetd mode (-i). This bug
1138 was introduced by release 1.4.
1140 --- 1.4pl1 1998/1/29
1142 Added sort facility in client and backend server interface.
1144 Fixed problem with dependencies in Makefile(s).
1146 Fixed bugs for encoders/decoders of extended services and
1149 Implemented sub-tree feature for schemas. Sub-trees are
1150 referenced in *.abs-files. See explain.abs for an example
1151 of the use of this feature.
1153 Modified bib1.att; local attributes for ANY didn't include
1154 ANY itself (only affects use of the retrieval module).
1156 Fixed bug in plain SGML reader in function data1_read_node:
1157 tags with prefix "var" was incorrectly interpreted as variants.
1159 Added feature "sub-schemas" to enable references to - and definitions
1160 of - group of elements.
1162 * Removed member parent from type data1_element (in data1.h).
1164 Implemented function odr_nullval() that returns the value of
1167 * Removed member num_children from data1_node (in data1.h).
1169 Made NT service interface part of the server library. The
1170 function statserv_main uses the NT service when required and
1171 calls the statserv_start / statserv_close routines.
1173 Routine zget_SearchRequest and zget_PresentRequest fills
1174 resultSetName/Id member with "default" instead of "Default".
1176 Fixed memory leak in server. Request queue member wasn't freed.
1178 Fixed nmem_exit so that memory is freed.
1182 Revised the CCL parser utility to be thread safe.
1184 Added function, oid_ent_to_oid, to replace the function
1185 oid_getoidbyent, which is not thread safe.
1187 * Added nmem_init and nmem_exit to initialize and release
1188 NMEM resources. Function nmem_init should be called once in the
1189 initial thread before NMEM/ODR is used. statserv.c and client.c
1190 have been changed accordingly. The change was necessary to make
1191 NMEM thread safe. The NMEM memory pool is shared amongst threads
1192 in a process. Unix-based applications will still work fine without
1195 Added NT Services interface for the the Z39.50 (statserv) Server.
1196 Refer to the ztest.c source on the usage.
1198 Windows 95/NT port using MSVC5.0. Project files are included in the
1201 * Defined new 'global' handle for the retrieval (data1) system. The
1202 new handled, data1_handle, describes the state of the data1 system.
1203 This handle is passed as first argument to virtually all
1204 data1 related routines. The functions data1_create and data1_destroy
1205 creates and destroys a data1 handle respectively.
1207 Added ODR encode stream member to all backend request structures
1208 init, search, scan etc. This stream should be used to allocate all
1209 memory used for the response when thread safe operation is needed.
1211 Changed the comstack utility, cs_addstr, to be thread safe. The
1212 returned hostname string returned by the function is now part the
1215 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1216 function. The cs_straddr takes a COMSTACK handle as argument, so this
1217 function must be used after cs_create and before bind/connect.
1218 This function is thread safe.
1220 Moved test server to 'ztest' directory - generic server code still
1221 in 'server' directory.
1223 Made prefix query (pquery.c) utility thread safe.
1225 Added new function modifier YAZ_EXPORT to 'export' public DLL
1226 functions when using windows (see include/yconfig.h).
1228 Added definitions to the OID database (util/oid.c) (RVDM).
1230 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1232 Added call to ccl_rpn_delete in client program.
1234 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1235 release of RPN structure.
1237 Added support for C++, headers uses extern "C" for public definitions.
1238 With input from RVDM.
1240 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1241 Thanks to Ronald van der Meer (RVDM).
1243 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1245 Added support for private extensions to the OID database
1246 (oid_setprivateoids()). Thanks to RVDM.
1248 Added optional, physical ANY (key replication)
1250 Fixed null-reference problem in GRS-1 output filter.
1252 Proximity operator added to Prefix Query Format (PQF).
1254 In test client command "base" accepts multiple databases.
1256 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1260 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1262 Smallish bug-fixes in the new encoders/decoders (explain).
1264 Bug fixed in DeleteRequest.
1266 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1268 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1270 Added SOIF syntax (using private OID for now) to retrieval module and client.
1272 Added Update extended service.
1274 Added SearchResult-1 additional info structure.
1276 Added optional CCL (ISO8777) interpreter as separate module. Available
1279 --- 1.2 1996/6/10 (1st anniversary release)
1281 Added Summary record syntax. Lightly tested.
1283 Added OPAC record syntax. Untested.
1285 Added ResourceReport service encoders/decoders. Untested.
1287 Fixed bug in z_Unit - wrong tagging on unitSystem.
1289 Fixed bug in the DiagRecs decoder.
1291 Added options for max PDU size and session timeout to frontend-server.
1293 Added documentation of query-language parsers and other supporting utilities.
1295 [frontend-server] Added Attribute set to the bend_scanrequest API.
1297 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1298 surrogate diagnostics were generated.
1300 [retrieval] Allow multiple local values for attribute.
1302 [retrieval] Allow multiple attributes per element in .abs files. index type.
1304 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1306 --- 1.1pl2 1996/4/10
1308 Minor changes, mostly specific to Zebra's requirements (retrieval)
1312 Repaired bug in frontend server when running multiple listening
1313 endpoints in dynamic mode.
1315 z_External() now won't break if a known, ASN.1 value comes encapsulated
1316 in an octet-string. The value will pass through unmodified in an Odr_oct.
1318 Added a bit of code to the demo client to decode & display
1319 ASN.1-structured records represented in the octet-aligned branch of
1320 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1322 Added z_ext_getentbyref() to the ASN module. Doc updated.
1324 * Completed the SCAN definition in the ASN module. This may break SCAN
1325 code based on older YAZ-versions at compile-time. The fix is easy -
1328 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1329 under the SCAN definition. Remember to initialize this, server-people.
1331 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1332 that this does not extend to ODR and ASN.
1334 Comstack allows insertion of established socket (primarily for
1335 inetd-operation of servers). Doc updated.
1337 Front-end server can now start from the inetd in TCP mode. Doc
1340 --- 1.0pl4 1996/1/24
1344 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1345 the rank and record number.
1347 Adjustments to the frontend server.
1349 Fixed diagnostic BER dumper. It ignored the file argument.
1353 Various changes to retrieval module.
1355 Changed the union discriminators of the protocol files from enums to
1356 ints paired with #defines.
1358 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1361 *Changed operator in the RPN structure to 'roperator', again to avoid a
1364 Fixed problems in Explain decoders/encoders.
1366 --- 1.0pl2 1995/12/6
1368 Memory bug in log module fixed.
1370 --- 1.0pl1 1995/12/5
1372 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1374 Bug in Explain DatabaseInfo module fixed.
1376 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1380 The shift to v1.0 signals that we now consider the *core* functionality
1381 of YAZ reasonably stable (the core being more or less equivalent to
1382 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1383 tested (Explain not at all - though that will happen soonish).
1385 Minor changes to code to support Windows port.
1387 Various minor changes after we're getting to use GRS-1 & co. more.
1389 Added Espec-1 format.
1391 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1392 of the protocol and it cannot be selected when encoding (maps into 'string'
1393 when decoding). Needed to talk to some servers.
1395 Demo client can request simple element set names.
1397 Added Diagnostic Format encoders/decoders.
1399 Added simple Close handling to frontend server (no hooks for resource
1400 reporting yet), and demonstration client.
1402 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1404 --- 1.0b3 1995/08/24
1406 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1407 handled incorrectly when records were requested in the searchResponse. This
1408 will only affect you if you use the frontend-server.
1410 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1411 Test-client will ask for and print GRS1. Ztest will return dummy records
1414 Added Explain encoders/decoders to the service-level API. Untested.
1416 Added Extended Services: Item Order encoders and decoders to the Service-
1417 level API. Untested. We could use a recent copy of the pertinent bits
1418 of the ILL protocol to add those bits.
1420 Added diagnostic format 1 encoders/decoders to the service-level API.
1423 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1424 odr_cons.c, which causes a more correct output.
1426 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1427 was always set to 0 when no records were requested in the searchRequest.
1429 * Added better external-handling. This shouldn't harm old code that
1430 *encodes* externals. It can break code that looks for a
1431 'single-ASN1-type' representation, since those types that are known
1432 are now decoded immediately. Look at the SUTRS sample code in
1433 seshigh.c and client.c. Documentation updated.
1435 Handling of structured records in bend_fetchresponse. Length -1 marks
1436 structured record, type is deduced from format field.
1438 --- 1.0b2 1995/06/27
1439 Fairly quick maintenance release to add SUTRS support.
1441 Fixed handling of SUTRS records in the demonstration client.
1443 * Added format field to the bend_fetchrequest and bend_fetchresponce
1444 structures of the backend API (frontend server). When the record is
1445 returned, the value of the format field is mapped to an OID. The
1446 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1447 of the record. The special value VAL_NONE in the bend_request means
1448 that no specific format was requested by the client. Documentation
1449 updated accordingly. Test server (ztest) will return a fixed dummy
1450 SUTRS record if your client requests SUTRS.
1452 Documentation updated accordingly.
1454 You can now set external libraries and RANLIB support in the top-level
1458 First public release.
