1 Possible compatibility problems with earlier versions marked with '*'.
3 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
4 instead of LOG_, due to name clash with syslog(3). LOG_ are still
5 present. New applications should define YAZ_USE_NEW_LOG=1 - this
6 will effectively disable old definitions.
10 Added yaz_log_time_format which specifies log format using
13 Added yaz_log_module_level which returns mask for a module. Value
14 is non-zero mask a if module is enabled; zero if disabled.
16 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
19 Fixed bug #176: Dont throw diagnostics on empty SRU args.
21 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
23 Fixed bug #172: RPM builds does not enable SSL.
25 Doxyfile.in part of dist. Doxyfile generated by configure.
27 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
28 are given and the corresponding component does not exist.
30 Extend CCL documentation in YAZ reference. Describe r=r.
34 Fixed MARC->MARCXML conversion to properly deal with
35 fields, subfields, indicators having non-ASCII characters.
37 Fixed MARC->MARCXML conversion so that ASCII control characters
38 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
41 Added YAZ GFS support for conversion from Z39.50 surrogate
42 diagnostics to SRW surrogate diagnostics.
44 Bug fix: YAZ GFS did not return schema in explainResponse.
48 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
49 now converts recordSchema to elementSetName as well as schema URI.
51 Fixed bug in COMSTACK that prevented HTTP request packages from being
56 Added CCL facility r=r "range" which is similar to r=o "ordered" but
57 does not require white-space before and after the dash in a range, e.g.
58 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
61 Fixed a few AC_TRY_LINK configure tests that did not operate properly
62 due to new GCC removing "redundant" code.
64 Added yaz-client commands scanpos and scanstep that sets preferred
65 position and step-size for scan.
67 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
69 Added CCL utility ccl_qual_buf which parses one or more CCL
70 spec lines in a buffer.
72 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
73 of name and value - ignoring empty lines and comments.
75 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
77 Added odr_get_element_path which returns current element path for an
78 ODR handle. This utility is useful in error handling or user-defined
81 Added ODR_PRINT utility odr_set_stream which is is a more generic
82 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
83 to a write function and pointer to close function. The close function - if
84 non-NULL - will be called during odr_destroy.
86 Fixed bug in CCL parser where truncation char was not removed from
87 right side when truncation=both was in effect.
89 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
94 Fix buffer overrun in CQL parser when dealing with proximity (%).
96 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
97 to UTF-8/UCS conversion is now only based on codetables.xml.
99 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
101 --- 2.0.22 2004/08/06
103 Add support for more "commit changes" in ZOOM (uses Extended Services).
105 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
108 Yet another small fix for configure of SSL.
110 --- 2.0.21 2004/05/14
112 Fix SSL libs for configure when --with-openssl=DIR is given.
114 --- 2.0.20 2004/05/10
116 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
118 SSL comstack now uses yaz.pem certificate file on server side
119 by default. Certificate filename can be configured by calling
120 comstack function cs_set_ssl_certificate_file before cs_bind is used.
122 Fix bug regarding multiple calls to ZOOM_connection_connect.
124 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
126 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
127 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
129 ZOOM now allows inspection of X509 peer certificate for verification.
130 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
132 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
133 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
134 as "modular" but it simplifies things.
136 Added cs_get_peer_certificate to that returns peer X509 PEM.
138 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
139 NULL if SSL is unavailable.
141 Documentation about MARC decoding tools.
143 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
145 --- 2.0.19 2004/03/30
147 Rename CHANGELOG to NEWS to follow GNU style packing.
149 Fix bug with missing initialization of member in init_diagnostics.
150 This bug affects threaded version of GFS server.
152 --- 2.0.18 2004/03/20
154 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
157 Ensure zlib.dll is packed with Windows install.
159 --- 2.0.17 2004/03/17
161 Fix encoding of xsd:string to use text instead of CDATA.
163 Fix endless loop in CQL parser with unbalanced ".
165 Use a more compact way to store MARC-8 conversion tables.
167 --- 2.0.16 2004/03/16 Debian only
169 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
172 Update CQL parser to use new CQL 1.1 modifiers for booleans and
177 --- 2.0.15 2004/03/01
179 Another fix for decoding of XML packed records.
181 --- 2.0.14 2004/02/25
183 Fixes for Chunked encoding. White space not ignored after length spec.
185 Update NS and use default NS for SRW diagnostic elements.
187 --- 2.0.13 2004/02/23
189 Implement ZOOM_resultset_cache_reset which resets record cache.
191 Implement ZOOM_resultset_sort which sorts a result set.
193 Implement chunked HTTP transfer.
195 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
197 --- 2.0.12 2004/02/16
199 Added member 'schema' to bend_explain_rr structure so that backend
200 can specify explain record identifier. Defaults to Zeerex 2.0.
202 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
204 --- 2.0.11 2004/02/16
206 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
209 Added init command for yaz-client which sends "extra" init request.
211 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
212 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
214 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
216 Make ZOOM error code for "invalid query".
218 Fixed compilation for SSL which wasn't properly enabled for all platforms.
220 --- 2.0.10 2004/02/05
222 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
225 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
227 Added option -p <file> to make Generic Frontend Server to write PID file.
229 Added option -D to put Generic Frontend Server in background on its own.
231 Make ZOOM C recognize option "password". If unset, "pass" is used
232 (for backwards compatibility).
234 Fixed a bug in Generic Frontend Server that could make it crash if a
235 client sets characterSetNegotation bit, but didn't pass negotiation stuff
238 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
239 Must be issued before open, in order to be in effect.
241 --- 2.0.9-6 2004/01/12 Debian/Windows
243 Make the SRU server more picky WRT unknown params, etc.
245 Bug fix: ZOOM scan response didn't return displayTerm - when present.
247 New YAZ client command, options, that sets Z39.50 options.
249 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
250 options from a string of tokens (one token for each option bit).
252 Update SRW diagnostic code messages.
254 --- 2.0.9-5 2004/01/07 Debian/Windows
256 Handle user defined stylesheet for SRW/SRU.
258 --- 2.0.9-4 2004/01/06 Debian/Windows
260 Fix bug in decoding of Content-Length.
262 --- 2.0.9-3 2004/01/06 Debian/Windows
264 Fix a bug with decoding of XML packed records.
266 --- 2.0.9-2 2004/01/05 Debian only
268 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
270 Fix bug in SRW/SRU diagnostics decoding.
274 Fixed bug in Generic Frontend Server which could drop records exceeding
275 preferred message size. Reported and fixed by Irina Dijour.
277 Fixed calculation of package size for structured records in Generic
278 Frontend Server. Reported and fixed by Irina Dijour.
280 Fixed namespace for SRW/SRU diagnostics.
282 Fixed SEGV in yaz-client that occured for HTTP connection errors.
286 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
287 this version is incompatible with version 1.0 and older YAZ SRW/SRU
290 CQL changes to reflect recent changes to the specification:
291 * Documentation talks about context sets instead of index sets.
292 * Documentation talks about indexes instead of qualifiers.
293 * The CQL-to-PQF transformer's configuration file now uses
294 "index.set.name = <attributes>" instead of the old form
295 "qualifier.set.name = <attributes>". (Both forms are still
296 understood but the latter is deprecated.)
297 * CQL terms with no explicit index specified are now interpreted as
298 cql.serverChoice instead of srw.serverChoice (which of course
299 behaves exactly the same.)
303 MARC conversion can now generate ISO2709 output in another
304 character set. yaz-marcdump uses this facility if you invoke it
307 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
308 functions from there can be used from C++.
312 Frontend server now transfers memory from decoded packages to stream
315 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
316 references to show up.
318 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
319 the ZOOM Abstract API. The older names for the same options are still
320 also supported for the benefit of old applications.
322 ZOOM-C supports "implementationId" and "implementationVersion" options
323 to go along with "implementationName". These allow the user code to
324 specify identification strings to be sent to servers.
325 Add OID for the new ExtLite attribute set.
327 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
328 as requested/supplid by Ere Maijala <ere@atp.fi>
330 For generic frontend server, reverse the order of
331 "toolkit-supplied / application-supplied" strings sent as implementationId,
332 Name and Version. Also, remove the spaces around the slash. This brings
333 the GFS in line with the behaviour of ZOOM-C on the client side.
335 Add function ZOOM_scanset_display_term.
337 yaz-client shows scan displayTerm if present.
339 Utility yaz-iconv is now installed by default along with the man page
342 Extend configure check for OpenSSL to use pkg-config where available (such
345 Incorporate patch by Morten Bogeskov which allows a Unix file socket
346 server to specify uid/gid/mask for socket using the format
347 unix:[user=uid,][group=gid,][umask=mask,]file=path
348 If file= is omitted the existing format is assumed, e.g.
350 in which case the mask is 0666 (rw for everybody).
352 Major restructure of YAZ source. All source in libyaz is in src directory.
353 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
354 util (utility programs such as ASN.1 compiler, yaz-marcdump).
356 Added man page for utility yaz-marcdump (used to be called marcdump).
357 yaz-marcdump is installed by 'make install'.
359 Fixed a memory leak in Generic Frontend Server that occurred when decoding
360 of incoming package failed.
362 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
364 Change prototype of odr_perror: add const to message string.
366 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
368 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
369 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
370 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
371 DNS lookup. There should not be any compatibility problems with this
372 assuming that blocking=1 or 0 is used.
374 Fix bad reference in UNIX comstack in function cs_addrstr.
376 Fix for compilation on AIX.
378 The generic front-end server (server/seshigh.c) now supports returning
379 Init diagnostics to the client in User-information-field, in
380 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
385 Allow any CQL relation (not just all,any,exact,scr).
387 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
388 that features the same UI.
390 Implemented command update0 in YAZ client which is equivalent to
391 update but uses old of Ext Update ASN.1.
393 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
394 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
395 Previously no OID was used for this info.
397 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
398 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
399 returns 'malformed search term' otherwise.
401 SortResponse member resultCount now set to NULL in sort handler of
404 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
407 Add three new utility functions for translating OIDs between various
408 formats -- symbolic name such as "Usmarc", minus-1-terminated int
409 arrays and dotted strings such as "1.2.840.10003.9.5.1":
410 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
411 char *oid_to_dotstring(const int *oid, char *oidbuf);
412 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
414 Reverted modifications for ES Update definition for z_IU0Update
415 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
416 is back to YAZ 2.0.2.
418 String value attributes for CCL parser.
420 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
421 which their FirstSearch server returns in Init responses, sometimes
422 carrying useful diagnostic information when Init fails. This has the
423 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
424 "z39.50/oclcui.asn", where its definition is somewhat different from
425 what OCLC document on their web-site, as required to interoperate with
428 Support for anonymous authentication in yaz-client. Use the command
431 * Fix the OID of the Index Data-local "admin" Extended Service from
432 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
433 the 1000, which indicates a locally-defined OID, was a mistake.
437 Fix CCL directive @case handling so that it affects string match for
438 both CCL keywords and qualifiers.
440 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
441 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
442 Decoder has been updated with ASN.1 changes as listed in
443 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
444 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
445 z_IUUpdate, remains unchanged.
447 ZOOM_record_get may now return a record in a specific character set.
448 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
449 "from" is the character set of record as returned by target. "to" is
450 the character set to be returned. If omitted, "to" is UTF-8.
452 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
454 New ODR utility, odr_getelement, which returns name of element for
455 which encoding/decoding failed.
457 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
458 in cases where a required element was omitted.
460 Bug fix: some MARC8 sequences were not converted.
462 New ZOOM option "step" which specifies number of records to be
463 retrieved in one chunk. Used in conjunction with "start" and "count".
465 SRW support for yaz-client. Use scheme http: to use it, e.g.
468 yaz-client no longer does (un)intelligent character set conversions
469 by default. Can be enabled with charset and marc_charset commands.
471 xmalloc trace fix for 64-bit systems such as DEC alpha.
473 Solaris 2.6 compile fix.
475 New function, cql_strerror() translates SRW error codes, as returned
476 by cql_transform_error(), into human-readable English strings. Used
477 in yaz-client diagnostics when appropriate.
479 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
480 converts it into a type-1 query which is sent to the server. This
481 makes CQL available for use with all Z-servers, as opposed to the tiny
482 minority that can handle CQL queries themselves.
486 New Debian package layout similar to the Redhat Package layout.
488 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
489 and search result respectively.
493 Redhat package is now several packages: libyaz (runtime libraries),
494 libyaz-devel (development and documentation, and yaz (utility programs).
495 Package spec file by Morten Bøgeskov.
497 New member 'schema' in struct bend_fetch_rr which the name of requested
498 schema (SRW/SRU) for record (or NULL if none was given). The fetch
499 handler MAY set this to reflect the schema of the returned record.
501 New member 'display_term' in struct scan_entry. GFS now sets member entries
502 and allocates scan entries to be filled by user scan handler. In previous
503 version, entries member was allocated by the scan handler. That still works,
504 but the GFS will ignore member display_term - assuming it was NOT set by
505 the handler. The fact that the GFS now allocates the entries both allows
506 for new members and makes a scan handler easier to write.
508 Fix CQL lex buffer overflow.
510 SRW/SRU recordPacking. For SRW default recordPacking is string. For
511 SRU default recordPacking is string.
513 SRU protocol support for frontend server.
515 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
517 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
519 Added scan for the ZOOM shell (zoomsh).
523 * String Identifers for Schemas (Amendment 5).
524 http://lcweb.loc.gov/z3950/agency/amend/am5.html
525 Old definition for schema
526 Odr_oid *schema; /* OPT */
531 Z_InternationalString *uri;
532 #define Z_Schema_oid 1
533 #define Z_Schema_uri 2
536 * resultCount parameter to Sort Response (Amendment 1).
537 http://lcweb.loc.gov/z3950/agency/amend/am1.html
539 Support for SRW 1.0 over HTTP. This is an optional feature and
540 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
543 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
544 on the same port. SRW SearchRetrieveRequests are mapped
545 to bend_init,bend_search,bend_fetch,bend_close.
547 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
549 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
550 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
552 ZOOM connections are SRW based if schem http is used for hostname
553 in connect, e.g. z = ZOOM_connection_new("http://myserver");
554 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
556 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
557 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
558 distance=n, order=true/false, relation=le, prox unit=word. If
559 n is omitted, distance 1 is used.
561 Fixed problem with C compiler include path in wrong order.
563 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
564 on Solaris. Patch from Ko van der Sloot.
566 New MARC decode API. All new functions operate on a yaz_marc_t
567 handle. The most important new functions are: yaz_marc_create,
568 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
569 decode and destroy respectively. Decoder can produce formats
570 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
571 include/yaz/marcdisp.h.
573 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
574 to UTF-8, UCS-32, wchar_t or Latin-1.
576 * Prototypes for yaz_iconv_-functions moved to separate header
577 include/yaz/yaz-iconv.h.
579 Make a few private functions 'static' in unix.c. This prevents
580 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
582 For ZOOM connection, the options targetImplementation{Id,Name,Version}
583 are set when Init Response is received.
585 New function ZOOM_connection_error_x similar to ZOOM_connection_error
586 but returns diagnostic set as well.
588 New function yaz_strerror which is a portable wrapper for
589 strerror/strerror_r/GetLastMessage.
591 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
592 is returned for MARC. If type is "oai", then OAI MARC is returned.
594 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
599 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
601 Fix bad race conditions on SIGTERM and terminate gracefully in
604 Move retrieval (data1) module to Zebra since nobody seems to be
607 Add GRS-1 render for ZOOM using same format as yaz-client.
611 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
613 Fix broken ESpec handling in data1 module.
615 SGML reader parses comments and makes them part of the data1 tree.
617 Added several type casts so that YAZ compiles as C++ code.
619 ZOOM didn't handle PDU encoding failures properly.
621 Added more Bib-1 diagnostics (approved extensions).
623 GNU configure: better check for iconv.
625 More portable use of accept, getpeername. Check for socklen_t. Use
626 int/size_t if socklen_t is not defined.
630 PQF parser rejects bad queries - including those with extra
631 characters in them. PQF parser used to silently ignore that.
632 Cleaner API for PQF added, which allows you to get detailed
633 error information for bad queries (see yaz/pquery.h).
635 Fixed bug in ZOOM_record_get for type "database".
637 Implemented mini iconv library supporting conversions between
638 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
640 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
644 Fixed ZOOM C record cache so that preferredRecordSyntax and
645 elementSetName is used to check for already fetched records.
649 Added three members in bend_initrequest structure to facilitate
650 character set negotiation.
652 Fixed a bug in frontend server that could cause indefinite
653 loops under rare conditions.
655 Revised character set utilities (charneg.h) so that encoding
656 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
658 For PQF, directive @term <type> sets term type for Scan/Search.
659 Here <type> is general, string, numeric, null. The term type
660 is inherited - just like @attr.
662 New call odr_set_charset that sets character set conversion for
663 international-strings on a ODR stream. Prototype is:
664 int odr_set_charset(ODR o, const char *to, const char *from);
665 The InternationalString is still represented as C string in YAZ
666 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
667 won't). On the protocol level, you can use any encoding.
669 Support for UNIX sockets in ZOOM.
671 Solaris recv sometimes returns errno == ENOENT. It is treated as
672 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
674 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
675 both client and server. Code by Morten Bøgeskov.
679 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
680 that they can be used directly from Visual Basic. You must recompile
681 your windows APP if you're using ZOOM.
683 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
684 Commands "lang" and "charset" sets language and character set respectively.
685 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
686 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
688 Attributes from multiple CCL fields may be OR'ed rather than merged
689 using directive "@field or". Fields are still merged by default -
690 equivalent to "@field merge".
692 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
695 Fixed bug in zget for parameter ExtendedServicesResponse.
701 Added PQF feature: '@attr type=value' may be written as '@type=value'.
703 Client displays USR.1:SearchResult-1 (hits per term).
705 Additional Search Info for search in Generic Frontend Server.
707 Fixed CCL parsing of "field=s".
709 WIN32 installer - using the excellent NSIS software from nullsoft.
711 Fixed CCL parsing of "field = - <number>".
713 Added function yaz_marc_decode that decodes MARC for line mode
714 display or XML (similar to that used by JZKit).
716 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
717 Z39.50. But ISO/ILL was, however.
719 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
720 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

727 New YAZ client features: Command completion and new commands:
728 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
729 Code provided by Jacob Poulsen.
731 New call oid_trav, that visits all registered OIDs via callback.
733 Function ZOOM_record_get now returns const char pointer rather than
734 void pointer. It saves a lot of type casts.
736 For YAZ client, command "auth" now allows you to set authentication
737 in IdPass style. It is enabled when three tokens are given - order
738 is user, group and password.
740 Fix memory leaks in MARC record handling for ZOOM.
742 New option for YAZ client, -k <kilobytes> that sets
743 maximum record size. Similar to -k option for generic frontend
744 server and yaz-ztest.
746 More fixes for scan. Non-zero stepSize handled. OID's fixes.
748 Prefix query parser reports "fail" when bad attribute set is given.
750 Fix in MARC decoder. Proximity logging. Fix for attribute set
751 in scan handler for server. Patches by Shigeru Ishida.
753 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
756 Configure option --with-openssl=<dir> now works when a directory is
757 specified. Patch provided by Morten Bøgeskov.
759 New option for YAZ client, -u <auth>, that sets authentication.
761 ZOOM fix: error information was sometimes "missing", since error
762 was cleared/reset too when it shouldn't.
764 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
768 Scan for ZOOM API. New object ZOOM_scanset. New functions
769 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
770 ZOOM_scanset_destroy.
772 New ZOOM function, ZOOM_connection_last_event, that returns type
773 of last event (such as "receive data", "send data", "apdu received",
776 New ZOOM option, schema, that specifies schema for retrieval.
778 New CCL feature. Qualifiers can be aliases for one or more
779 other qualifiers (if more than one is given, OR is used).
781 ZOOM uses named result sets if target supports it.
783 Two new YAZ client commands: . (dot, which sources a script of YAZ
784 client commands), and ! (to execute shell command.). Implemented
787 Working on Debian packages.
791 YAZ client enables named result sets only if target supports it.
793 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
795 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
796 with key="host" to get same result.
798 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
799 Function Z3950_resultset_record(s) returns references to records
800 "owned" by resultset. To become owner use Z3950_record_clone.
802 Function z_ext_record handles Extended Services. Thanks to
807 CCL Parser fix: ignore token comma when dealing with and-lists.
809 Documentation updates for COMSTACK.
811 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
812 Changed prototype Z3950_records. For some functions, int parameters
813 were changed to size_t.
815 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
818 New MARC decode/display function, marc_display_exl, which properly rejects
819 non-ISO2709 records. YAZ client uses it.
823 Fix bug: local attribute set wasn't set correctly in PQF strings.
827 * Old Z39.50 codecs no longer supported.
829 Added ZOOM C binding. See http://zoom.z3950.org/
831 Renamed states for COMSTACKs to avoid confusion with events.
833 Implemented cs_look and proper cs_rcvconnect.
835 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
837 Configure detects POSIX threads on OpenBSD.
839 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
840 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
842 When error is returned from present handler, non-surrogate diagnostic
843 is returned in present response (and fetch handler is no longer called).
845 * Minor adjustments to pquery parser (PQF). Token characters may be
846 escaped by using backslash (C-style).
848 PQF parser allows string attribute values to be specified. For @attr,
849 non-numeric characters after the equal-sign are treated as strings
850 (e.g. @attr 9=title).
852 CCL trunction character may be defined (@truncation in file)
854 * function zget_ExtendedServicesRequest sets waitAction to
855 waitIfPossible (was wait).
857 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
860 CCL operator names may be set in field definition files (CCL_bibset).
861 See ccl/bib1 for an example.
863 Fixes in ASN.1 compiler for C++ compatibility.
865 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
866 and "op_or" to avoid conflict with C++.
868 Fixed problem with GNU readline detection on Redhat 7.0.
870 Added step-size for Scan backend handler.
872 Fixed bug that made the frontend server crash when no attribute
873 set was specified for scan.
875 Front-end server automatically switches to original working directory
876 when installed as an NT service. Previously -w had to be specified to
879 Added extended attributes for retrieval module (data1), so that data1
880 records carry d1_readXML/SGML attributes. d1_read also supports
881 null-data rules ( <tag/>)
883 On UNIX when POSIX threads are available, a separate library libyazthread
884 is created. Programmers should link with that library and the yaz library
885 when using threads. The reason for the split was that some applications
886 on Linux, such as Apache, doesn't work well when using shared objects that
889 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
890 (or any frontend server) in SSL mode by specifying ssl: followed by
891 address. Only tested on UNIX.
893 Added feature for CCL module. Virtual structure s=al or s=ol generates
894 and-list and or-list respectively instead of phrase search.
898 * Added prefix "yaz_" for the functions log_init.., log_file.. and
899 log_mask_str. This was done to avoid name conflicts with other libraries
900 (such as other PHP extensions).
902 Added raw OID member for preferred record syntax (request_format_raw)
903 and returned record syntax (output_format_raw) for backend fetch method.
905 Config file yaz-config now accepts options so that it returns specific
906 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
908 Shared library support for UNIX using GNU libtool.
910 * Modified backend interface. Request/Response struct's replaced by
911 one read/write C struct. For example bend_fetchrequest and
912 bend_fetchresult have been replaced by single bend_fetch_rr struct.
913 Every handler - even search has to be registered in bend_init
914 handler. This means that the YAZ library no longer refers to
915 external functions and it makes it possible to make the whole
916 thing a single DLL/SO.
918 Added Segment handler for backend server.
920 Added Zmbol/Zebra administrative functions to YAZ client.
922 Threaded frontend server on UNIX (when POSIX Threads are available).
923 Starting the server with option -T enables multi-threading.
927 Added configure option --enable-comp/disable-comp to control use
928 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
929 located in sub directory asn.
931 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
932 in ${exec_prefix}/bin along with the other programs yaz-client and
935 GNU automake used to maintain makefiles.
939 Changed retrieval module so that we can load records with no abstract
940 syntax defined. Tagpaths in these records are fully composed of string
943 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
947 On UNIX, the generated makefile now supports a proper 'make install'.
948 The prefix can be set via GNU configure to set the install location
949 (default is /usr/local).
951 * YAZ programs client and ztest were renamed to yaz-client and
952 yaz-ztest to avoid conflicts when users install YAZ in "standard"
953 locations, such as /usr/bin,/usr/local/bin,etc.
955 * YAZ Header files were moved from include to include/yaz. YAZ Header
956 files are referred to as include <yaz/log.h> rather than <log.h>.
957 The YAZ include path (-I ..) is therefore the same as before. Programmers
958 should update their #include statements or use -Ipath/include/yaz
959 instead. The main motivation for doing this change is that YAZ header files
960 can be installed in "standard" locations /usr/include,/usr/local/include
961 without introducing conflicts, since ALL YAZ header files are stored
962 in subdirectory yaz (under /usr/include for example).
964 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
965 rather than project/workspace files. We switched because project files
966 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
969 Changed name of logging function, logf, to yaz_log, to prevent name
970 clash with some math-log functions. The YAZ header log.h defines logf
971 to yaz_log (#define) so there should be no incompatibilities by this
974 Added bend_start/bend_stop handlers for server. These handler are
975 called on start/stop of server. For windows they are called whenever
976 a service is started/stopped.
978 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
979 a fairly small ASN.1 compiler written in Tcl. The compiler is located
980 in util/yc.tcl. The auto-generated C code structures are, in a few
981 cases, incompatible with the old decoders. There are differences in the
982 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
983 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
984 The preprocessor variable ASN_COMPILED is defined when the compiled
985 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
986 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
987 wish to use the old encoders/decoders you can specify --disable-yc
990 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
991 version so that it supports both new - and old version of DB Update
993 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
994 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
995 change. The name parameter can be set to 0 in which no name is specified
996 for the construction. The macros odr_implicit and odr_explicit sets name
997 parameter to zero for the construction involved. New macros
998 odr_implicit_tag and odr_explicit_tag are similar to the others,
999 except that a name parameter is added. For programmers' that don't use
1000 ODR they probably only need to change the call to z_APDU and z_External.
1002 Added access control facility by interfacing the TCP wrapper library.
1003 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1004 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1005 name of the daemon and enables the access control as specified in
1006 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1008 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1009 den Dool <H.M.vdnDool@kub.nl>.
1011 Added reference ID parameter to most functions in server API - refer
1012 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1014 Changed name of ccl library to libccl.a (was ccl.a).
1016 Fixed bug in decoder for Explain (Category TargetInfo).
1018 Added support for GNU readline in client. Thanks to Jacob Poulsen
1019 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1021 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1022 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1023 IMPLEMENTATION! This change was made to the development version before
1024 the ZIG decided to retract the amendment. If any users MUST be
1025 compatible with the original Update definition, PLEASE CONTACT US, and
1026 we will include a separate definition corresponding to the old Update
1027 ES. Note that because of the change to the ASN.1 of the
1028 TaskPackageRecordStructure we cannot define a single structure that
1029 will support both versions.
1031 * Added const modifier to buffer parameter for some ODR/BER encoding
1032 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1033 completeWAIS, odr_dumpBER.
1035 Fixed bug in client.c which caused a crash when a scanResponse didn't
1036 contain positionOfTerm.
1038 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1039 * will cause an error in a client if a non-YAZ target sends both a
1040 * list of Scan entries and non-surrogate diagnostics.
1042 Retrieval module enhancements. Tag sets may be typed in the reference
1043 to it. From the .abs-file the "tagset" directive takes a third optional
1044 integer type for the tag set referenced. From a .tag-file the "include"
1045 directive takes a third optional type as well. The old "type" directive
1046 in the tag set itself is still recognized but acts as the default type
1049 Backend interface change. Individual Scan terms returned from bend_scan
1050 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1051 in include/backend.h.
1053 Retrieval module enhancements. Multiple tag sets and attribute sets may
1054 be specified in abstract syntax specs. Revised the error/warning for
1055 logging messages reported by the retrieval module when reading the
1058 Object Identifier system (oid_..) changed. The API is backwards
1059 compatible but the oid-routines now allocates new OID's when needed.
1060 Raw OID's may be specified in oid_getvalbyname.
1062 YAZ now uses GNU configure to generate Makefile(s).
1064 * Minor changes in some of the member names of DeleteResultSetRequest and
1065 DeleteResultSetResponse. See include/proto.h.
1067 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1068 and added member 'languages' in TargetInfo (which was missing).
1070 Changed the way attribute sets are handled in the retrieval
1071 module. These are now cached, just like the abstract syntaxes
1074 Changed YAZ so that it links with compiled ASN.1.
1076 Added Explain-schema definitions and mapping routines. The following
1077 Explain categories have been implemented: AttributeDetails,
1078 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1080 Fixed minor bug in Windows version of Server Library.
1082 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1084 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1086 Added EXTERNAL: UNIverse Resource Report (non-standard).
1088 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1089 ENUMERATED and SET OF.
1091 * Added 'const' to some of the char pointer arguments for the
1092 functions, data1_read_node, data1_getelementbytagname,
1093 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1096 Fixed bug in data1_insert_taggeddata - the last_child member of
1097 parent wasn't initialised.
1099 * Changed data1_read_record and data1_read_node so that the supplied
1100 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1101 doesn't refer to any parts of the "SGML"-buffer.
1103 Fixed bug in server library (Windows version of statserv_remove).
1105 * Changed code so that it compiles as C++. The type definition
1106 of Odr_fun which is a member of Odr_arm was changed. The result is,
1107 that an explicit typecast is needed for the fun pointer when
1108 using Odr_arm - as in:
1109 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1111 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1113 Implemented the new structured date and time definition as approved
1114 by the ZIG. Added schemaId element to the specificTag in Espec-1
1115 (also approved at the last ZIG). Thanks to RVDM.
1117 Added some Object identifiers (RVDM).
1119 Changed the Update Extended Service (RVDM).
1121 Added command "refid" to client which specifies referenceId for
1122 the following requests.
1124 Implemented extended service handling for server. See ztest.c
1125 for an example as well as backend.h. New handlers are registerd
1126 in the Init handler.
1128 * Changed interface for sort in server.
1130 Added new members to statserv_options_block. It allows a server
1131 to read options from another source than just the command line. Thanks
1132 to Charles Woodfield.
1134 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1135 renamed to zboolean. Some C++ compilers complained about the name.
1137 Minor changes to gils.abs. Added index 's' (sort) on title
1138 and date/time-last-modified.
1140 --- 1.4pl2 1998/1/30
1142 Fixed bug in server library regarding inetd mode (-i). This bug
1143 was introduced by release 1.4.
1145 --- 1.4pl1 1998/1/29
1147 Added sort facility in client and backend server interface.
1149 Fixed problem with dependencies in Makefile(s).
1151 Fixed bugs for encoders/decoders of extended services and
1154 Implemented sub-tree feature for schemas. Sub-trees are
1155 referenced in *.abs-files. See explain.abs for an example
1156 of the use of this feature.
1158 Modified bib1.att; local attributes for ANY didn't include
1159 ANY itself (only affects use of the retrieval module).
1161 Fixed bug in plain SGML reader in function data1_read_node:
1162 tags with prefix "var" was incorrectly interpreted as variants.
1164 Added feature "sub-schemas" to enable references to - and definitions
1165 of - group of elements.
1167 * Removed member parent from type data1_element (in data1.h).
1169 Implemented function odr_nullval() that returns the value of
1172 * Removed member num_children from data1_node (in data1.h).
1174 Made NT service interface part of the server library. The
1175 function statserv_main uses the NT service when required and
1176 calls the statserv_start / statserv_close routines.
1178 Routine zget_SearchRequest and zget_PresentRequest fills
1179 resultSetName/Id member with "default" instead of "Default".
1181 Fixed memory leak in server. Request queue member wasn't freed.
1183 Fixed nmem_exit so that memory is freed.
1187 Revised the CCL parser utility to be thread safe.
1189 Added function, oid_ent_to_oid, to replace the function
1190 oid_getoidbyent, which is not thread safe.
1192 * Added nmem_init and nmem_exit to initialize and release
1193 NMEM resources. Function nmem_init should be called once in the
1194 initial thread before NMEM/ODR is used. statserv.c and client.c
1195 have been changed accordingly. The change was necessary to make
1196 NMEM thread safe. The NMEM memory pool is shared amongst threads
1197 in a process. Unix-based applications will still work fine without
1200 Added NT Services interface for the the Z39.50 (statserv) Server.
1201 Refer to the ztest.c source on the usage.
1203 Windows 95/NT port using MSVC5.0. Project files are included in the
1206 * Defined new 'global' handle for the retrieval (data1) system. The
1207 new handled, data1_handle, describes the state of the data1 system.
1208 This handle is passed as first argument to virtually all
1209 data1 related routines. The functions data1_create and data1_destroy
1210 creates and destroys a data1 handle respectively.
1212 Added ODR encode stream member to all backend request structures
1213 init, search, scan etc. This stream should be used to allocate all
1214 memory used for the response when thread safe operation is needed.
1216 Changed the comstack utility, cs_addstr, to be thread safe. The
1217 returned hostname string returned by the function is now part the
1220 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1221 function. The cs_straddr takes a COMSTACK handle as argument, so this
1222 function must be used after cs_create and before bind/connect.
1223 This function is thread safe.
1225 Moved test server to 'ztest' directory - generic server code still
1226 in 'server' directory.
1228 Made prefix query (pquery.c) utility thread safe.
1230 Added new function modifier YAZ_EXPORT to 'export' public DLL
1231 functions when using windows (see include/yconfig.h).
1233 Added definitions to the OID database (util/oid.c) (RVDM).
1235 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1237 Added call to ccl_rpn_delete in client program.
1239 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1240 release of RPN structure.
1242 Added support for C++, headers uses extern "C" for public definitions.
1243 With input from RVDM.
1245 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1246 Thanks to Ronald van der Meer (RVDM).
1248 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1250 Added support for private extensions to the OID database
1251 (oid_setprivateoids()). Thanks to RVDM.
1253 Added optional, physical ANY (key replication)
1255 Fixed null-reference problem in GRS-1 output filter.
1257 Proximity operator added to Prefix Query Format (PQF).
1259 In test client command "base" accepts multiple databases.
1261 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1265 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1267 Smallish bug-fixes in the new encoders/decoders (explain).
1269 Bug fixed in DeleteRequest.
1271 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1273 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1275 Added SOIF syntax (using private OID for now) to retrieval module and client.
1277 Added Update extended service.
1279 Added SearchResult-1 additional info structure.
1281 Added optional CCL (ISO8777) interpreter as separate module. Available
1284 --- 1.2 1996/6/10 (1st anniversary release)
1286 Added Summary record syntax. Lightly tested.
1288 Added OPAC record syntax. Untested.
1290 Added ResourceReport service encoders/decoders. Untested.
1292 Fixed bug in z_Unit - wrong tagging on unitSystem.
1294 Fixed bug in the DiagRecs decoder.
1296 Added options for max PDU size and session timeout to frontend-server.
1298 Added documentation of query-language parsers and other supporting utilities.
1300 [frontend-server] Added Attribute set to the bend_scanrequest API.
1302 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1303 surrogate diagnostics were generated.
1305 [retrieval] Allow multiple local values for attribute.
1307 [retrieval] Allow multiple attributes per element in .abs files. index type.
1309 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1311 --- 1.1pl2 1996/4/10
1313 Minor changes, mostly specific to Zebra's requirements (retrieval)
1317 Repaired bug in frontend server when running multiple listening
1318 endpoints in dynamic mode.
1320 z_External() now won't break if a known, ASN.1 value comes encapsulated
1321 in an octet-string. The value will pass through unmodified in an Odr_oct.
1323 Added a bit of code to the demo client to decode & display
1324 ASN.1-structured records represented in the octet-aligned branch of
1325 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1327 Added z_ext_getentbyref() to the ASN module. Doc updated.
1329 * Completed the SCAN definition in the ASN module. This may break SCAN
1330 code based on older YAZ-versions at compile-time. The fix is easy -
1333 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1334 under the SCAN definition. Remember to initialize this, server-people.
1336 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1337 that this does not extend to ODR and ASN.
1339 Comstack allows insertion of established socket (primarily for
1340 inetd-operation of servers). Doc updated.
1342 Front-end server can now start from the inetd in TCP mode. Doc
1345 --- 1.0pl4 1996/1/24
1349 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1350 the rank and record number.
1352 Adjustments to the frontend server.
1354 Fixed diagnostic BER dumper. It ignored the file argument.
1358 Various changes to retrieval module.
1360 Changed the union discriminators of the protocol files from enums to
1361 ints paired with #defines.
1363 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1366 *Changed operator in the RPN structure to 'roperator', again to avoid a
1369 Fixed problems in Explain decoders/encoders.
1371 --- 1.0pl2 1995/12/6
1373 Memory bug in log module fixed.
1375 --- 1.0pl1 1995/12/5
1377 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1379 Bug in Explain DatabaseInfo module fixed.
1381 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1385 The shift to v1.0 signals that we now consider the *core* functionality
1386 of YAZ reasonably stable (the core being more or less equivalent to
1387 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1388 tested (Explain not at all - though that will happen soonish).
1390 Minor changes to code to support Windows port.
1392 Various minor changes after we're getting to use GRS-1 & co. more.
1394 Added Espec-1 format.
1396 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1397 of the protocol and it cannot be selected when encoding (maps into 'string'
1398 when decoding). Needed to talk to some servers.
1400 Demo client can request simple element set names.
1402 Added Diagnostic Format encoders/decoders.
1404 Added simple Close handling to frontend server (no hooks for resource
1405 reporting yet), and demonstration client.
1407 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1409 --- 1.0b3 1995/08/24
1411 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1412 handled incorrectly when records were requested in the searchResponse. This
1413 will only affect you if you use the frontend-server.
1415 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1416 Test-client will ask for and print GRS1. Ztest will return dummy records
1419 Added Explain encoders/decoders to the service-level API. Untested.
1421 Added Extended Services: Item Order encoders and decoders to the Service-
1422 level API. Untested. We could use a recent copy of the pertinent bits
1423 of the ILL protocol to add those bits.
1425 Added diagnostic format 1 encoders/decoders to the service-level API.
1428 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1429 odr_cons.c, which causes a more correct output.
1431 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1432 was always set to 0 when no records were requested in the searchRequest.
1434 * Added better external-handling. This shouldn't harm old code that
1435 *encodes* externals. It can break code that looks for a
1436 'single-ASN1-type' representation, since those types that are known
1437 are now decoded immediately. Look at the SUTRS sample code in
1438 seshigh.c and client.c. Documentation updated.
1440 Handling of structured records in bend_fetchresponse. Length -1 marks
1441 structured record, type is deduced from format field.
1443 --- 1.0b2 1995/06/27
1444 Fairly quick maintenance release to add SUTRS support.
1446 Fixed handling of SUTRS records in the demonstration client.
1448 * Added format field to the bend_fetchrequest and bend_fetchresponce
1449 structures of the backend API (frontend server). When the record is
1450 returned, the value of the format field is mapped to an OID. The
1451 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1452 of the record. The special value VAL_NONE in the bend_request means
1453 that no specific format was requested by the client. Documentation
1454 updated accordingly. Test server (ztest) will return a fixed dummy
1455 SUTRS record if your client requests SUTRS.
1457 Documentation updated accordingly.
1459 You can now set external libraries and RANLIB support in the top-level
1463 First public release.
