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). The new header for
5 YAZ log is <yaz/ylog.h>. The old definitions are kept in <yaz/log.h>
6 with all old definitions with values kept - so all applications should
7 compile as usual. See "Log" chapter in YAZ manual.
11 Added yaz_log_time_format which specifies log format using
14 Added yaz_log_module_level which returns mask for a module. Value
15 is non-zero mask a if module is enabled; zero if disabled.
17 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
20 Fixed bug #176: Dont throw diagnostics on empty SRU args.
22 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
24 Fixed bug #172: RPM builds does not enable SSL.
26 Doxyfile.in part of dist. Doxyfile generated by configure.
28 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
29 are given and the corresponding component does not exist.
31 Extend CCL documentation in YAZ reference. Describe r=r.
35 Fixed MARC->MARCXML conversion to properly deal with
36 fields, subfields, indicators having non-ASCII characters.
38 Fixed MARC->MARCXML conversion so that ASCII control characters
39 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
42 Added YAZ GFS support for conversion from Z39.50 surrogate
43 diagnostics to SRW surrogate diagnostics.
45 Bug fix: YAZ GFS did not return schema in explainResponse.
49 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
50 now converts recordSchema to elementSetName as well as schema URI.
52 Fixed bug in COMSTACK that prevented HTTP request packages from being
57 Added CCL facility r=r "range" which is similar to r=o "ordered" but
58 does not require white-space before and after the dash in a range, e.g.
59 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
62 Fixed a few AC_TRY_LINK configure tests that did not operate properly
63 due to new GCC removing "redundant" code.
65 Added yaz-client commands scanpos and scanstep that sets preferred
66 position and step-size for scan.
68 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
70 Added CCL utility ccl_qual_buf which parses one or more CCL
71 spec lines in a buffer.
73 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
74 of name and value - ignoring empty lines and comments.
76 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
78 Added odr_get_element_path which returns current element path for an
79 ODR handle. This utility is useful in error handling or user-defined
82 Added ODR_PRINT utility odr_set_stream which is is a more generic
83 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
84 to a write function and pointer to close function. The close function - if
85 non-NULL - will be called during odr_destroy.
87 Fixed bug in CCL parser where truncation char was not removed from
88 right side when truncation=both was in effect.
90 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
95 Fix buffer overrun in CQL parser when dealing with proximity (%).
97 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
98 to UTF-8/UCS conversion is now only based on codetables.xml.
100 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
102 --- 2.0.22 2004/08/06
104 Add support for more "commit changes" in ZOOM (uses Extended Services).
106 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
109 Yet another small fix for configure of SSL.
111 --- 2.0.21 2004/05/14
113 Fix SSL libs for configure when --with-openssl=DIR is given.
115 --- 2.0.20 2004/05/10
117 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
119 SSL comstack now uses yaz.pem certificate file on server side
120 by default. Certificate filename can be configured by calling
121 comstack function cs_set_ssl_certificate_file before cs_bind is used.
123 Fix bug regarding multiple calls to ZOOM_connection_connect.
125 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
127 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
128 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
130 ZOOM now allows inspection of X509 peer certificate for verification.
131 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
133 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
134 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
135 as "modular" but it simplifies things.
137 Added cs_get_peer_certificate to that returns peer X509 PEM.
139 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
140 NULL if SSL is unavailable.
142 Documentation about MARC decoding tools.
144 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
146 --- 2.0.19 2004/03/30
148 Rename CHANGELOG to NEWS to follow GNU style packing.
150 Fix bug with missing initialization of member in init_diagnostics.
151 This bug affects threaded version of GFS server.
153 --- 2.0.18 2004/03/20
155 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
158 Ensure zlib.dll is packed with Windows install.
160 --- 2.0.17 2004/03/17
162 Fix encoding of xsd:string to use text instead of CDATA.
164 Fix endless loop in CQL parser with unbalanced ".
166 Use a more compact way to store MARC-8 conversion tables.
168 --- 2.0.16 2004/03/16 Debian only
170 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
173 Update CQL parser to use new CQL 1.1 modifiers for booleans and
178 --- 2.0.15 2004/03/01
180 Another fix for decoding of XML packed records.
182 --- 2.0.14 2004/02/25
184 Fixes for Chunked encoding. White space not ignored after length spec.
186 Update NS and use default NS for SRW diagnostic elements.
188 --- 2.0.13 2004/02/23
190 Implement ZOOM_resultset_cache_reset which resets record cache.
192 Implement ZOOM_resultset_sort which sorts a result set.
194 Implement chunked HTTP transfer.
196 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
198 --- 2.0.12 2004/02/16
200 Added member 'schema' to bend_explain_rr structure so that backend
201 can specify explain record identifier. Defaults to Zeerex 2.0.
203 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
205 --- 2.0.11 2004/02/16
207 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
210 Added init command for yaz-client which sends "extra" init request.
212 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
213 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
215 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
217 Make ZOOM error code for "invalid query".
219 Fixed compilation for SSL which wasn't properly enabled for all platforms.
221 --- 2.0.10 2004/02/05
223 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
226 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
228 Added option -p <file> to make Generic Frontend Server to write PID file.
230 Added option -D to put Generic Frontend Server in background on its own.
232 Make ZOOM C recognize option "password". If unset, "pass" is used
233 (for backwards compatibility).
235 Fixed a bug in Generic Frontend Server that could make it crash if a
236 client sets characterSetNegotation bit, but didn't pass negotiation stuff
239 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
240 Must be issued before open, in order to be in effect.
242 --- 2.0.9-6 2004/01/12 Debian/Windows
244 Make the SRU server more picky WRT unknown params, etc.
246 Bug fix: ZOOM scan response didn't return displayTerm - when present.
248 New YAZ client command, options, that sets Z39.50 options.
250 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
251 options from a string of tokens (one token for each option bit).
253 Update SRW diagnostic code messages.
255 --- 2.0.9-5 2004/01/07 Debian/Windows
257 Handle user defined stylesheet for SRW/SRU.
259 --- 2.0.9-4 2004/01/06 Debian/Windows
261 Fix bug in decoding of Content-Length.
263 --- 2.0.9-3 2004/01/06 Debian/Windows
265 Fix a bug with decoding of XML packed records.
267 --- 2.0.9-2 2004/01/05 Debian only
269 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
271 Fix bug in SRW/SRU diagnostics decoding.
275 Fixed bug in Generic Frontend Server which could drop records exceeding
276 preferred message size. Reported and fixed by Irina Dijour.
278 Fixed calculation of package size for structured records in Generic
279 Frontend Server. Reported and fixed by Irina Dijour.
281 Fixed namespace for SRW/SRU diagnostics.
283 Fixed SEGV in yaz-client that occured for HTTP connection errors.
287 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
288 this version is incompatible with version 1.0 and older YAZ SRW/SRU
291 CQL changes to reflect recent changes to the specification:
292 * Documentation talks about context sets instead of index sets.
293 * Documentation talks about indexes instead of qualifiers.
294 * The CQL-to-PQF transformer's configuration file now uses
295 "index.set.name = <attributes>" instead of the old form
296 "qualifier.set.name = <attributes>". (Both forms are still
297 understood but the latter is deprecated.)
298 * CQL terms with no explicit index specified are now interpreted as
299 cql.serverChoice instead of srw.serverChoice (which of course
300 behaves exactly the same.)
304 MARC conversion can now generate ISO2709 output in another
305 character set. yaz-marcdump uses this facility if you invoke it
308 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
309 functions from there can be used from C++.
313 Frontend server now transfers memory from decoded packages to stream
316 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
317 references to show up.
319 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
320 the ZOOM Abstract API. The older names for the same options are still
321 also supported for the benefit of old applications.
323 ZOOM-C supports "implementationId" and "implementationVersion" options
324 to go along with "implementationName". These allow the user code to
325 specify identification strings to be sent to servers.
326 Add OID for the new ExtLite attribute set.
328 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
329 as requested/supplid by Ere Maijala <ere@atp.fi>
331 For generic frontend server, reverse the order of
332 "toolkit-supplied / application-supplied" strings sent as implementationId,
333 Name and Version. Also, remove the spaces around the slash. This brings
334 the GFS in line with the behaviour of ZOOM-C on the client side.
336 Add function ZOOM_scanset_display_term.
338 yaz-client shows scan displayTerm if present.
340 Utility yaz-iconv is now installed by default along with the man page
343 Extend configure check for OpenSSL to use pkg-config where available (such
346 Incorporate patch by Morten Bogeskov which allows a Unix file socket
347 server to specify uid/gid/mask for socket using the format
348 unix:[user=uid,][group=gid,][umask=mask,]file=path
349 If file= is omitted the existing format is assumed, e.g.
351 in which case the mask is 0666 (rw for everybody).
353 Major restructure of YAZ source. All source in libyaz is in src directory.
354 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
355 util (utility programs such as ASN.1 compiler, yaz-marcdump).
357 Added man page for utility yaz-marcdump (used to be called marcdump).
358 yaz-marcdump is installed by 'make install'.
360 Fixed a memory leak in Generic Frontend Server that occurred when decoding
361 of incoming package failed.
363 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
365 Change prototype of odr_perror: add const to message string.
367 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
369 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
370 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
371 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
372 DNS lookup. There should not be any compatibility problems with this
373 assuming that blocking=1 or 0 is used.
375 Fix bad reference in UNIX comstack in function cs_addrstr.
377 Fix for compilation on AIX.
379 The generic front-end server (server/seshigh.c) now supports returning
380 Init diagnostics to the client in User-information-field, in
381 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
386 Allow any CQL relation (not just all,any,exact,scr).
388 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
389 that features the same UI.
391 Implemented command update0 in YAZ client which is equivalent to
392 update but uses old of Ext Update ASN.1.
394 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
395 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
396 Previously no OID was used for this info.
398 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
399 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
400 returns 'malformed search term' otherwise.
402 SortResponse member resultCount now set to NULL in sort handler of
405 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
408 Add three new utility functions for translating OIDs between various
409 formats -- symbolic name such as "Usmarc", minus-1-terminated int
410 arrays and dotted strings such as "1.2.840.10003.9.5.1":
411 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
412 char *oid_to_dotstring(const int *oid, char *oidbuf);
413 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
415 Reverted modifications for ES Update definition for z_IU0Update
416 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
417 is back to YAZ 2.0.2.
419 String value attributes for CCL parser.
421 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
422 which their FirstSearch server returns in Init responses, sometimes
423 carrying useful diagnostic information when Init fails. This has the
424 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
425 "z39.50/oclcui.asn", where its definition is somewhat different from
426 what OCLC document on their web-site, as required to interoperate with
429 Support for anonymous authentication in yaz-client. Use the command
432 * Fix the OID of the Index Data-local "admin" Extended Service from
433 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
434 the 1000, which indicates a locally-defined OID, was a mistake.
438 Fix CCL directive @case handling so that it affects string match for
439 both CCL keywords and qualifiers.
441 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
442 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
443 Decoder has been updated with ASN.1 changes as listed in
444 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
445 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
446 z_IUUpdate, remains unchanged.
448 ZOOM_record_get may now return a record in a specific character set.
449 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
450 "from" is the character set of record as returned by target. "to" is
451 the character set to be returned. If omitted, "to" is UTF-8.
453 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
455 New ODR utility, odr_getelement, which returns name of element for
456 which encoding/decoding failed.
458 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
459 in cases where a required element was omitted.
461 Bug fix: some MARC8 sequences were not converted.
463 New ZOOM option "step" which specifies number of records to be
464 retrieved in one chunk. Used in conjunction with "start" and "count".
466 SRW support for yaz-client. Use scheme http: to use it, e.g.
469 yaz-client no longer does (un)intelligent character set conversions
470 by default. Can be enabled with charset and marc_charset commands.
472 xmalloc trace fix for 64-bit systems such as DEC alpha.
474 Solaris 2.6 compile fix.
476 New function, cql_strerror() translates SRW error codes, as returned
477 by cql_transform_error(), into human-readable English strings. Used
478 in yaz-client diagnostics when appropriate.
480 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
481 converts it into a type-1 query which is sent to the server. This
482 makes CQL available for use with all Z-servers, as opposed to the tiny
483 minority that can handle CQL queries themselves.
487 New Debian package layout similar to the Redhat Package layout.
489 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
490 and search result respectively.
494 Redhat package is now several packages: libyaz (runtime libraries),
495 libyaz-devel (development and documentation, and yaz (utility programs).
496 Package spec file by Morten Bøgeskov.
498 New member 'schema' in struct bend_fetch_rr which the name of requested
499 schema (SRW/SRU) for record (or NULL if none was given). The fetch
500 handler MAY set this to reflect the schema of the returned record.
502 New member 'display_term' in struct scan_entry. GFS now sets member entries
503 and allocates scan entries to be filled by user scan handler. In previous
504 version, entries member was allocated by the scan handler. That still works,
505 but the GFS will ignore member display_term - assuming it was NOT set by
506 the handler. The fact that the GFS now allocates the entries both allows
507 for new members and makes a scan handler easier to write.
509 Fix CQL lex buffer overflow.
511 SRW/SRU recordPacking. For SRW default recordPacking is string. For
512 SRU default recordPacking is string.
514 SRU protocol support for frontend server.
516 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
518 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
520 Added scan for the ZOOM shell (zoomsh).
524 * String Identifers for Schemas (Amendment 5).
525 http://lcweb.loc.gov/z3950/agency/amend/am5.html
526 Old definition for schema
527 Odr_oid *schema; /* OPT */
532 Z_InternationalString *uri;
533 #define Z_Schema_oid 1
534 #define Z_Schema_uri 2
537 * resultCount parameter to Sort Response (Amendment 1).
538 http://lcweb.loc.gov/z3950/agency/amend/am1.html
540 Support for SRW 1.0 over HTTP. This is an optional feature and
541 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
544 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
545 on the same port. SRW SearchRetrieveRequests are mapped
546 to bend_init,bend_search,bend_fetch,bend_close.
548 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
550 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
551 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
553 ZOOM connections are SRW based if schem http is used for hostname
554 in connect, e.g. z = ZOOM_connection_new("http://myserver");
555 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
557 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
558 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
559 distance=n, order=true/false, relation=le, prox unit=word. If
560 n is omitted, distance 1 is used.
562 Fixed problem with C compiler include path in wrong order.
564 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
565 on Solaris. Patch from Ko van der Sloot.
567 New MARC decode API. All new functions operate on a yaz_marc_t
568 handle. The most important new functions are: yaz_marc_create,
569 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
570 decode and destroy respectively. Decoder can produce formats
571 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
572 include/yaz/marcdisp.h.
574 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
575 to UTF-8, UCS-32, wchar_t or Latin-1.
577 * Prototypes for yaz_iconv_-functions moved to separate header
578 include/yaz/yaz-iconv.h.
580 Make a few private functions 'static' in unix.c. This prevents
581 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
583 For ZOOM connection, the options targetImplementation{Id,Name,Version}
584 are set when Init Response is received.
586 New function ZOOM_connection_error_x similar to ZOOM_connection_error
587 but returns diagnostic set as well.
589 New function yaz_strerror which is a portable wrapper for
590 strerror/strerror_r/GetLastMessage.
592 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
593 is returned for MARC. If type is "oai", then OAI MARC is returned.
595 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
600 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
602 Fix bad race conditions on SIGTERM and terminate gracefully in
605 Move retrieval (data1) module to Zebra since nobody seems to be
608 Add GRS-1 render for ZOOM using same format as yaz-client.
612 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
614 Fix broken ESpec handling in data1 module.
616 SGML reader parses comments and makes them part of the data1 tree.
618 Added several type casts so that YAZ compiles as C++ code.
620 ZOOM didn't handle PDU encoding failures properly.
622 Added more Bib-1 diagnostics (approved extensions).
624 GNU configure: better check for iconv.
626 More portable use of accept, getpeername. Check for socklen_t. Use
627 int/size_t if socklen_t is not defined.
631 PQF parser rejects bad queries - including those with extra
632 characters in them. PQF parser used to silently ignore that.
633 Cleaner API for PQF added, which allows you to get detailed
634 error information for bad queries (see yaz/pquery.h).
636 Fixed bug in ZOOM_record_get for type "database".
638 Implemented mini iconv library supporting conversions between
639 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
641 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
645 Fixed ZOOM C record cache so that preferredRecordSyntax and
646 elementSetName is used to check for already fetched records.
650 Added three members in bend_initrequest structure to facilitate
651 character set negotiation.
653 Fixed a bug in frontend server that could cause indefinite
654 loops under rare conditions.
656 Revised character set utilities (charneg.h) so that encoding
657 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
659 For PQF, directive @term <type> sets term type for Scan/Search.
660 Here <type> is general, string, numeric, null. The term type
661 is inherited - just like @attr.
663 New call odr_set_charset that sets character set conversion for
664 international-strings on a ODR stream. Prototype is:
665 int odr_set_charset(ODR o, const char *to, const char *from);
666 The InternationalString is still represented as C string in YAZ
667 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
668 won't). On the protocol level, you can use any encoding.
670 Support for UNIX sockets in ZOOM.
672 Solaris recv sometimes returns errno == ENOENT. It is treated as
673 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
675 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
676 both client and server. Code by Morten Bøgeskov.
680 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
681 that they can be used directly from Visual Basic. You must recompile
682 your windows APP if you're using ZOOM.
684 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
685 Commands "lang" and "charset" sets language and character set respectively.
686 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
687 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
689 Attributes from multiple CCL fields may be OR'ed rather than merged
690 using directive "@field or". Fields are still merged by default -
691 equivalent to "@field merge".
693 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
696 Fixed bug in zget for parameter ExtendedServicesResponse.
702 Added PQF feature: '@attr type=value' may be written as '@type=value'.
704 Client displays USR.1:SearchResult-1 (hits per term).
706 Additional Search Info for search in Generic Frontend Server.
708 Fixed CCL parsing of "field=s".
710 WIN32 installer - using the excellent NSIS software from nullsoft.
712 Fixed CCL parsing of "field = - <number>".
714 Added function yaz_marc_decode that decodes MARC for line mode
715 display or XML (similar to that used by JZKit).
717 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
718 Z39.50. But ISO/ILL was, however.
720 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
721 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

728 New YAZ client features: Command completion and new commands:
729 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
730 Code provided by Jacob Poulsen.
732 New call oid_trav, that visits all registered OIDs via callback.
734 Function ZOOM_record_get now returns const char pointer rather than
735 void pointer. It saves a lot of type casts.
737 For YAZ client, command "auth" now allows you to set authentication
738 in IdPass style. It is enabled when three tokens are given - order
739 is user, group and password.
741 Fix memory leaks in MARC record handling for ZOOM.
743 New option for YAZ client, -k <kilobytes> that sets
744 maximum record size. Similar to -k option for generic frontend
745 server and yaz-ztest.
747 More fixes for scan. Non-zero stepSize handled. OID's fixes.
749 Prefix query parser reports "fail" when bad attribute set is given.
751 Fix in MARC decoder. Proximity logging. Fix for attribute set
752 in scan handler for server. Patches by Shigeru Ishida.
754 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
757 Configure option --with-openssl=<dir> now works when a directory is
758 specified. Patch provided by Morten Bøgeskov.
760 New option for YAZ client, -u <auth>, that sets authentication.
762 ZOOM fix: error information was sometimes "missing", since error
763 was cleared/reset too when it shouldn't.
765 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
769 Scan for ZOOM API. New object ZOOM_scanset. New functions
770 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
771 ZOOM_scanset_destroy.
773 New ZOOM function, ZOOM_connection_last_event, that returns type
774 of last event (such as "receive data", "send data", "apdu received",
777 New ZOOM option, schema, that specifies schema for retrieval.
779 New CCL feature. Qualifiers can be aliases for one or more
780 other qualifiers (if more than one is given, OR is used).
782 ZOOM uses named result sets if target supports it.
784 Two new YAZ client commands: . (dot, which sources a script of YAZ
785 client commands), and ! (to execute shell command.). Implemented
788 Working on Debian packages.
792 YAZ client enables named result sets only if target supports it.
794 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
796 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
797 with key="host" to get same result.
799 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
800 Function Z3950_resultset_record(s) returns references to records
801 "owned" by resultset. To become owner use Z3950_record_clone.
803 Function z_ext_record handles Extended Services. Thanks to
808 CCL Parser fix: ignore token comma when dealing with and-lists.
810 Documentation updates for COMSTACK.
812 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
813 Changed prototype Z3950_records. For some functions, int parameters
814 were changed to size_t.
816 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
819 New MARC decode/display function, marc_display_exl, which properly rejects
820 non-ISO2709 records. YAZ client uses it.
824 Fix bug: local attribute set wasn't set correctly in PQF strings.
828 * Old Z39.50 codecs no longer supported.
830 Added ZOOM C binding. See http://zoom.z3950.org/
832 Renamed states for COMSTACKs to avoid confusion with events.
834 Implemented cs_look and proper cs_rcvconnect.
836 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
838 Configure detects POSIX threads on OpenBSD.
840 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
841 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
843 When error is returned from present handler, non-surrogate diagnostic
844 is returned in present response (and fetch handler is no longer called).
846 * Minor adjustments to pquery parser (PQF). Token characters may be
847 escaped by using backslash (C-style).
849 PQF parser allows string attribute values to be specified. For @attr,
850 non-numeric characters after the equal-sign are treated as strings
851 (e.g. @attr 9=title).
853 CCL trunction character may be defined (@truncation in file)
855 * function zget_ExtendedServicesRequest sets waitAction to
856 waitIfPossible (was wait).
858 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
861 CCL operator names may be set in field definition files (CCL_bibset).
862 See ccl/bib1 for an example.
864 Fixes in ASN.1 compiler for C++ compatibility.
866 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
867 and "op_or" to avoid conflict with C++.
869 Fixed problem with GNU readline detection on Redhat 7.0.
871 Added step-size for Scan backend handler.
873 Fixed bug that made the frontend server crash when no attribute
874 set was specified for scan.
876 Front-end server automatically switches to original working directory
877 when installed as an NT service. Previously -w had to be specified to
880 Added extended attributes for retrieval module (data1), so that data1
881 records carry d1_readXML/SGML attributes. d1_read also supports
882 null-data rules ( <tag/>)
884 On UNIX when POSIX threads are available, a separate library libyazthread
885 is created. Programmers should link with that library and the yaz library
886 when using threads. The reason for the split was that some applications
887 on Linux, such as Apache, doesn't work well when using shared objects that
890 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
891 (or any frontend server) in SSL mode by specifying ssl: followed by
892 address. Only tested on UNIX.
894 Added feature for CCL module. Virtual structure s=al or s=ol generates
895 and-list and or-list respectively instead of phrase search.
899 * Added prefix "yaz_" for the functions log_init.., log_file.. and
900 log_mask_str. This was done to avoid name conflicts with other libraries
901 (such as other PHP extensions).
903 Added raw OID member for preferred record syntax (request_format_raw)
904 and returned record syntax (output_format_raw) for backend fetch method.
906 Config file yaz-config now accepts options so that it returns specific
907 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
909 Shared library support for UNIX using GNU libtool.
911 * Modified backend interface. Request/Response struct's replaced by
912 one read/write C struct. For example bend_fetchrequest and
913 bend_fetchresult have been replaced by single bend_fetch_rr struct.
914 Every handler - even search has to be registered in bend_init
915 handler. This means that the YAZ library no longer refers to
916 external functions and it makes it possible to make the whole
917 thing a single DLL/SO.
919 Added Segment handler for backend server.
921 Added Zmbol/Zebra administrative functions to YAZ client.
923 Threaded frontend server on UNIX (when POSIX Threads are available).
924 Starting the server with option -T enables multi-threading.
928 Added configure option --enable-comp/disable-comp to control use
929 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
930 located in sub directory asn.
932 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
933 in ${exec_prefix}/bin along with the other programs yaz-client and
936 GNU automake used to maintain makefiles.
940 Changed retrieval module so that we can load records with no abstract
941 syntax defined. Tagpaths in these records are fully composed of string
944 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
948 On UNIX, the generated makefile now supports a proper 'make install'.
949 The prefix can be set via GNU configure to set the install location
950 (default is /usr/local).
952 * YAZ programs client and ztest were renamed to yaz-client and
953 yaz-ztest to avoid conflicts when users install YAZ in "standard"
954 locations, such as /usr/bin,/usr/local/bin,etc.
956 * YAZ Header files were moved from include to include/yaz. YAZ Header
957 files are referred to as include <yaz/log.h> rather than <log.h>.
958 The YAZ include path (-I ..) is therefore the same as before. Programmers
959 should update their #include statements or use -Ipath/include/yaz
960 instead. The main motivation for doing this change is that YAZ header files
961 can be installed in "standard" locations /usr/include,/usr/local/include
962 without introducing conflicts, since ALL YAZ header files are stored
963 in subdirectory yaz (under /usr/include for example).
965 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
966 rather than project/workspace files. We switched because project files
967 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
970 Changed name of logging function, logf, to yaz_log, to prevent name
971 clash with some math-log functions. The YAZ header log.h defines logf
972 to yaz_log (#define) so there should be no incompatibilities by this
975 Added bend_start/bend_stop handlers for server. These handler are
976 called on start/stop of server. For windows they are called whenever
977 a service is started/stopped.
979 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
980 a fairly small ASN.1 compiler written in Tcl. The compiler is located
981 in util/yc.tcl. The auto-generated C code structures are, in a few
982 cases, incompatible with the old decoders. There are differences in the
983 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
984 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
985 The preprocessor variable ASN_COMPILED is defined when the compiled
986 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
987 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
988 wish to use the old encoders/decoders you can specify --disable-yc
991 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
992 version so that it supports both new - and old version of DB Update
994 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
995 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
996 change. The name parameter can be set to 0 in which no name is specified
997 for the construction. The macros odr_implicit and odr_explicit sets name
998 parameter to zero for the construction involved. New macros
999 odr_implicit_tag and odr_explicit_tag are similar to the others,
1000 except that a name parameter is added. For programmers' that don't use
1001 ODR they probably only need to change the call to z_APDU and z_External.
1003 Added access control facility by interfacing the TCP wrapper library.
1004 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1005 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1006 name of the daemon and enables the access control as specified in
1007 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1009 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1010 den Dool <H.M.vdnDool@kub.nl>.
1012 Added reference ID parameter to most functions in server API - refer
1013 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1015 Changed name of ccl library to libccl.a (was ccl.a).
1017 Fixed bug in decoder for Explain (Category TargetInfo).
1019 Added support for GNU readline in client. Thanks to Jacob Poulsen
1020 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1022 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1023 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1024 IMPLEMENTATION! This change was made to the development version before
1025 the ZIG decided to retract the amendment. If any users MUST be
1026 compatible with the original Update definition, PLEASE CONTACT US, and
1027 we will include a separate definition corresponding to the old Update
1028 ES. Note that because of the change to the ASN.1 of the
1029 TaskPackageRecordStructure we cannot define a single structure that
1030 will support both versions.
1032 * Added const modifier to buffer parameter for some ODR/BER encoding
1033 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1034 completeWAIS, odr_dumpBER.
1036 Fixed bug in client.c which caused a crash when a scanResponse didn't
1037 contain positionOfTerm.
1039 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1040 * will cause an error in a client if a non-YAZ target sends both a
1041 * list of Scan entries and non-surrogate diagnostics.
1043 Retrieval module enhancements. Tag sets may be typed in the reference
1044 to it. From the .abs-file the "tagset" directive takes a third optional
1045 integer type for the tag set referenced. From a .tag-file the "include"
1046 directive takes a third optional type as well. The old "type" directive
1047 in the tag set itself is still recognized but acts as the default type
1050 Backend interface change. Individual Scan terms returned from bend_scan
1051 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1052 in include/backend.h.
1054 Retrieval module enhancements. Multiple tag sets and attribute sets may
1055 be specified in abstract syntax specs. Revised the error/warning for
1056 logging messages reported by the retrieval module when reading the
1059 Object Identifier system (oid_..) changed. The API is backwards
1060 compatible but the oid-routines now allocates new OID's when needed.
1061 Raw OID's may be specified in oid_getvalbyname.
1063 YAZ now uses GNU configure to generate Makefile(s).
1065 * Minor changes in some of the member names of DeleteResultSetRequest and
1066 DeleteResultSetResponse. See include/proto.h.
1068 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1069 and added member 'languages' in TargetInfo (which was missing).
1071 Changed the way attribute sets are handled in the retrieval
1072 module. These are now cached, just like the abstract syntaxes
1075 Changed YAZ so that it links with compiled ASN.1.
1077 Added Explain-schema definitions and mapping routines. The following
1078 Explain categories have been implemented: AttributeDetails,
1079 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1081 Fixed minor bug in Windows version of Server Library.
1083 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1085 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1087 Added EXTERNAL: UNIverse Resource Report (non-standard).
1089 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1090 ENUMERATED and SET OF.
1092 * Added 'const' to some of the char pointer arguments for the
1093 functions, data1_read_node, data1_getelementbytagname,
1094 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1097 Fixed bug in data1_insert_taggeddata - the last_child member of
1098 parent wasn't initialised.
1100 * Changed data1_read_record and data1_read_node so that the supplied
1101 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1102 doesn't refer to any parts of the "SGML"-buffer.
1104 Fixed bug in server library (Windows version of statserv_remove).
1106 * Changed code so that it compiles as C++. The type definition
1107 of Odr_fun which is a member of Odr_arm was changed. The result is,
1108 that an explicit typecast is needed for the fun pointer when
1109 using Odr_arm - as in:
1110 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1112 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1114 Implemented the new structured date and time definition as approved
1115 by the ZIG. Added schemaId element to the specificTag in Espec-1
1116 (also approved at the last ZIG). Thanks to RVDM.
1118 Added some Object identifiers (RVDM).
1120 Changed the Update Extended Service (RVDM).
1122 Added command "refid" to client which specifies referenceId for
1123 the following requests.
1125 Implemented extended service handling for server. See ztest.c
1126 for an example as well as backend.h. New handlers are registerd
1127 in the Init handler.
1129 * Changed interface for sort in server.
1131 Added new members to statserv_options_block. It allows a server
1132 to read options from another source than just the command line. Thanks
1133 to Charles Woodfield.
1135 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1136 renamed to zboolean. Some C++ compilers complained about the name.
1138 Minor changes to gils.abs. Added index 's' (sort) on title
1139 and date/time-last-modified.
1141 --- 1.4pl2 1998/1/30
1143 Fixed bug in server library regarding inetd mode (-i). This bug
1144 was introduced by release 1.4.
1146 --- 1.4pl1 1998/1/29
1148 Added sort facility in client and backend server interface.
1150 Fixed problem with dependencies in Makefile(s).
1152 Fixed bugs for encoders/decoders of extended services and
1155 Implemented sub-tree feature for schemas. Sub-trees are
1156 referenced in *.abs-files. See explain.abs for an example
1157 of the use of this feature.
1159 Modified bib1.att; local attributes for ANY didn't include
1160 ANY itself (only affects use of the retrieval module).
1162 Fixed bug in plain SGML reader in function data1_read_node:
1163 tags with prefix "var" was incorrectly interpreted as variants.
1165 Added feature "sub-schemas" to enable references to - and definitions
1166 of - group of elements.
1168 * Removed member parent from type data1_element (in data1.h).
1170 Implemented function odr_nullval() that returns the value of
1173 * Removed member num_children from data1_node (in data1.h).
1175 Made NT service interface part of the server library. The
1176 function statserv_main uses the NT service when required and
1177 calls the statserv_start / statserv_close routines.
1179 Routine zget_SearchRequest and zget_PresentRequest fills
1180 resultSetName/Id member with "default" instead of "Default".
1182 Fixed memory leak in server. Request queue member wasn't freed.
1184 Fixed nmem_exit so that memory is freed.
1188 Revised the CCL parser utility to be thread safe.
1190 Added function, oid_ent_to_oid, to replace the function
1191 oid_getoidbyent, which is not thread safe.
1193 * Added nmem_init and nmem_exit to initialize and release
1194 NMEM resources. Function nmem_init should be called once in the
1195 initial thread before NMEM/ODR is used. statserv.c and client.c
1196 have been changed accordingly. The change was necessary to make
1197 NMEM thread safe. The NMEM memory pool is shared amongst threads
1198 in a process. Unix-based applications will still work fine without
1201 Added NT Services interface for the the Z39.50 (statserv) Server.
1202 Refer to the ztest.c source on the usage.
1204 Windows 95/NT port using MSVC5.0. Project files are included in the
1207 * Defined new 'global' handle for the retrieval (data1) system. The
1208 new handled, data1_handle, describes the state of the data1 system.
1209 This handle is passed as first argument to virtually all
1210 data1 related routines. The functions data1_create and data1_destroy
1211 creates and destroys a data1 handle respectively.
1213 Added ODR encode stream member to all backend request structures
1214 init, search, scan etc. This stream should be used to allocate all
1215 memory used for the response when thread safe operation is needed.
1217 Changed the comstack utility, cs_addstr, to be thread safe. The
1218 returned hostname string returned by the function is now part the
1221 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1222 function. The cs_straddr takes a COMSTACK handle as argument, so this
1223 function must be used after cs_create and before bind/connect.
1224 This function is thread safe.
1226 Moved test server to 'ztest' directory - generic server code still
1227 in 'server' directory.
1229 Made prefix query (pquery.c) utility thread safe.
1231 Added new function modifier YAZ_EXPORT to 'export' public DLL
1232 functions when using windows (see include/yconfig.h).
1234 Added definitions to the OID database (util/oid.c) (RVDM).
1236 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1238 Added call to ccl_rpn_delete in client program.
1240 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1241 release of RPN structure.
1243 Added support for C++, headers uses extern "C" for public definitions.
1244 With input from RVDM.
1246 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1247 Thanks to Ronald van der Meer (RVDM).
1249 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1251 Added support for private extensions to the OID database
1252 (oid_setprivateoids()). Thanks to RVDM.
1254 Added optional, physical ANY (key replication)
1256 Fixed null-reference problem in GRS-1 output filter.
1258 Proximity operator added to Prefix Query Format (PQF).
1260 In test client command "base" accepts multiple databases.
1262 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1266 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1268 Smallish bug-fixes in the new encoders/decoders (explain).
1270 Bug fixed in DeleteRequest.
1272 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1274 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1276 Added SOIF syntax (using private OID for now) to retrieval module and client.
1278 Added Update extended service.
1280 Added SearchResult-1 additional info structure.
1282 Added optional CCL (ISO8777) interpreter as separate module. Available
1285 --- 1.2 1996/6/10 (1st anniversary release)
1287 Added Summary record syntax. Lightly tested.
1289 Added OPAC record syntax. Untested.
1291 Added ResourceReport service encoders/decoders. Untested.
1293 Fixed bug in z_Unit - wrong tagging on unitSystem.
1295 Fixed bug in the DiagRecs decoder.
1297 Added options for max PDU size and session timeout to frontend-server.
1299 Added documentation of query-language parsers and other supporting utilities.
1301 [frontend-server] Added Attribute set to the bend_scanrequest API.
1303 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1304 surrogate diagnostics were generated.
1306 [retrieval] Allow multiple local values for attribute.
1308 [retrieval] Allow multiple attributes per element in .abs files. index type.
1310 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1312 --- 1.1pl2 1996/4/10
1314 Minor changes, mostly specific to Zebra's requirements (retrieval)
1318 Repaired bug in frontend server when running multiple listening
1319 endpoints in dynamic mode.
1321 z_External() now won't break if a known, ASN.1 value comes encapsulated
1322 in an octet-string. The value will pass through unmodified in an Odr_oct.
1324 Added a bit of code to the demo client to decode & display
1325 ASN.1-structured records represented in the octet-aligned branch of
1326 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1328 Added z_ext_getentbyref() to the ASN module. Doc updated.
1330 * Completed the SCAN definition in the ASN module. This may break SCAN
1331 code based on older YAZ-versions at compile-time. The fix is easy -
1334 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1335 under the SCAN definition. Remember to initialize this, server-people.
1337 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1338 that this does not extend to ODR and ASN.
1340 Comstack allows insertion of established socket (primarily for
1341 inetd-operation of servers). Doc updated.
1343 Front-end server can now start from the inetd in TCP mode. Doc
1346 --- 1.0pl4 1996/1/24
1350 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1351 the rank and record number.
1353 Adjustments to the frontend server.
1355 Fixed diagnostic BER dumper. It ignored the file argument.
1359 Various changes to retrieval module.
1361 Changed the union discriminators of the protocol files from enums to
1362 ints paired with #defines.
1364 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1367 *Changed operator in the RPN structure to 'roperator', again to avoid a
1370 Fixed problems in Explain decoders/encoders.
1372 --- 1.0pl2 1995/12/6
1374 Memory bug in log module fixed.
1376 --- 1.0pl1 1995/12/5
1378 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1380 Bug in Explain DatabaseInfo module fixed.
1382 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1386 The shift to v1.0 signals that we now consider the *core* functionality
1387 of YAZ reasonably stable (the core being more or less equivalent to
1388 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1389 tested (Explain not at all - though that will happen soonish).
1391 Minor changes to code to support Windows port.
1393 Various minor changes after we're getting to use GRS-1 & co. more.
1395 Added Espec-1 format.
1397 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1398 of the protocol and it cannot be selected when encoding (maps into 'string'
1399 when decoding). Needed to talk to some servers.
1401 Demo client can request simple element set names.
1403 Added Diagnostic Format encoders/decoders.
1405 Added simple Close handling to frontend server (no hooks for resource
1406 reporting yet), and demonstration client.
1408 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1410 --- 1.0b3 1995/08/24
1412 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1413 handled incorrectly when records were requested in the searchResponse. This
1414 will only affect you if you use the frontend-server.
1416 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1417 Test-client will ask for and print GRS1. Ztest will return dummy records
1420 Added Explain encoders/decoders to the service-level API. Untested.
1422 Added Extended Services: Item Order encoders and decoders to the Service-
1423 level API. Untested. We could use a recent copy of the pertinent bits
1424 of the ILL protocol to add those bits.
1426 Added diagnostic format 1 encoders/decoders to the service-level API.
1429 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1430 odr_cons.c, which causes a more correct output.
1432 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1433 was always set to 0 when no records were requested in the searchRequest.
1435 * Added better external-handling. This shouldn't harm old code that
1436 *encodes* externals. It can break code that looks for a
1437 'single-ASN1-type' representation, since those types that are known
1438 are now decoded immediately. Look at the SUTRS sample code in
1439 seshigh.c and client.c. Documentation updated.
1441 Handling of structured records in bend_fetchresponse. Length -1 marks
1442 structured record, type is deduced from format field.
1444 --- 1.0b2 1995/06/27
1445 Fairly quick maintenance release to add SUTRS support.
1447 Fixed handling of SUTRS records in the demonstration client.
1449 * Added format field to the bend_fetchrequest and bend_fetchresponce
1450 structures of the backend API (frontend server). When the record is
1451 returned, the value of the format field is mapped to an OID. The
1452 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1453 of the record. The special value VAL_NONE in the bend_request means
1454 that no specific format was requested by the client. Documentation
1455 updated accordingly. Test server (ztest) will return a fixed dummy
1456 SUTRS record if your client requests SUTRS.
1458 Documentation updated accordingly.
1460 You can now set external libraries and RANLIB support in the top-level
1464 First public release.
