1 Possible compatibility problems with earlier versions marked with '*'.
3 Extended OPAC display utility. OPAC display utility renders
4 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
5 to supplement yaz_marc_decode_wrbuf.
9 Fixes for UNIX domain sockets. Bug #261.
11 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
13 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
14 Added yaz_marc_subfield_str which defines subfield lead string which is
15 used in YAZ_MARC_LINE format. Default string is blank+$. Added
16 yaz_marc_endline_str which defines end of fields string used in
17 YAZ_MARC_LINE format. Default string is newline.
19 Experimental support for MarcXChange. This format can be produced
20 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
21 http://www.bs.dk/standards/MarcXchange.xsd
23 Added yaz-client commands scansize that sets maximum number of
24 entries to be returned by scan.
28 Added support for SRW scan in yaz-client and Generic Frontend Server.
30 * Added whereInList member to SRW Scan Term.
32 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
34 Fixed NMEM system to return aligned blocks on the smallest boundaries
35 that are suitably aligned for all possible types on the particular
36 architecture YAZ is being built for.
40 Fixed numerious warnings that was issued with newer versions of GCC.
42 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
43 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
46 Make YAZ Generic Frontend Server slightly faster.
48 Enhance (and reduce) logging for Generic Frontend Server.
50 Revert YAZ log system so that it flushes every write operation
51 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
53 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
54 instead of LOG_, due to name clash with syslog(3). LOG_ are still
55 present. New applications should define YAZ_USE_NEW_LOG=1 - this
56 will effectively disable old definitions.
60 Added yaz_log_time_format which specifies log format using
63 Added yaz_log_module_level which returns mask for a module. Value
64 is non-zero mask a if module is enabled; zero if disabled.
66 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
69 Fixed bug #176: Dont throw diagnostics on empty SRU args.
71 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
73 Fixed bug #172: RPM builds does not enable SSL.
75 Doxyfile.in part of dist. Doxyfile generated by configure.
77 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
78 are given and the corresponding component does not exist.
80 Extend CCL documentation in YAZ reference. Describe r=r.
84 Fixed MARC->MARCXML conversion to properly deal with
85 fields, subfields, indicators having non-ASCII characters.
87 Fixed MARC->MARCXML conversion so that ASCII control characters
88 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
91 Added YAZ GFS support for conversion from Z39.50 surrogate
92 diagnostics to SRW surrogate diagnostics.
94 Bug fix: YAZ GFS did not return schema in explainResponse.
98 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
99 now converts recordSchema to elementSetName as well as schema URI.
101 Fixed bug in COMSTACK that prevented HTTP request packages from being
104 --- 2.0.24 2004/09/29
106 Added CCL facility r=r "range" which is similar to r=o "ordered" but
107 does not require white-space before and after the dash in a range, e.g.
108 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
111 Fixed a few AC_TRY_LINK configure tests that did not operate properly
112 due to new GCC removing "redundant" code.
114 Added yaz-client commands scanpos and scanstep that sets preferred
115 position and step-size for scan.
117 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
119 Added CCL utility ccl_qual_buf which parses one or more CCL
120 spec lines in a buffer.
122 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
123 of name and value - ignoring empty lines and comments.
125 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
127 Added odr_get_element_path which returns current element path for an
128 ODR handle. This utility is useful in error handling or user-defined
131 Added ODR_PRINT utility odr_set_stream which is is a more generic
132 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
133 to a write function and pointer to close function. The close function - if
134 non-NULL - will be called during odr_destroy.
136 Fixed bug in CCL parser where truncation char was not removed from
137 right side when truncation=both was in effect.
139 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
142 --- 2.0.23 2004/08/11
144 Fix buffer overrun in CQL parser when dealing with proximity (%).
146 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
147 to UTF-8/UCS conversion is now only based on codetables.xml.
149 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
151 --- 2.0.22 2004/08/06
153 Add support for more "commit changes" in ZOOM (uses Extended Services).
155 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
158 Yet another small fix for configure of SSL.
160 --- 2.0.21 2004/05/14
162 Fix SSL libs for configure when --with-openssl=DIR is given.
164 --- 2.0.20 2004/05/10
166 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
168 SSL comstack now uses yaz.pem certificate file on server side
169 by default. Certificate filename can be configured by calling
170 comstack function cs_set_ssl_certificate_file before cs_bind is used.
172 Fix bug regarding multiple calls to ZOOM_connection_connect.
174 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
176 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
177 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
179 ZOOM now allows inspection of X509 peer certificate for verification.
180 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
182 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
183 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
184 as "modular" but it simplifies things.
186 Added cs_get_peer_certificate to that returns peer X509 PEM.
188 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
189 NULL if SSL is unavailable.
191 Documentation about MARC decoding tools.
193 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
195 --- 2.0.19 2004/03/30
197 Rename CHANGELOG to NEWS to follow GNU style packing.
199 Fix bug with missing initialization of member in init_diagnostics.
200 This bug affects threaded version of GFS server.
202 --- 2.0.18 2004/03/20
204 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
207 Ensure zlib.dll is packed with Windows install.
209 --- 2.0.17 2004/03/17
211 Fix encoding of xsd:string to use text instead of CDATA.
213 Fix endless loop in CQL parser with unbalanced ".
215 Use a more compact way to store MARC-8 conversion tables.
217 --- 2.0.16 2004/03/16 Debian only
219 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
222 Update CQL parser to use new CQL 1.1 modifiers for booleans and
227 --- 2.0.15 2004/03/01
229 Another fix for decoding of XML packed records.
231 --- 2.0.14 2004/02/25
233 Fixes for Chunked encoding. White space not ignored after length spec.
235 Update NS and use default NS for SRW diagnostic elements.
237 --- 2.0.13 2004/02/23
239 Implement ZOOM_resultset_cache_reset which resets record cache.
241 Implement ZOOM_resultset_sort which sorts a result set.
243 Implement chunked HTTP transfer.
245 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
247 --- 2.0.12 2004/02/16
249 Added member 'schema' to bend_explain_rr structure so that backend
250 can specify explain record identifier. Defaults to Zeerex 2.0.
252 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
254 --- 2.0.11 2004/02/16
256 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
259 Added init command for yaz-client which sends "extra" init request.
261 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
262 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
264 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
266 Make ZOOM error code for "invalid query".
268 Fixed compilation for SSL which wasn't properly enabled for all platforms.
270 --- 2.0.10 2004/02/05
272 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
275 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
277 Added option -p <file> to make Generic Frontend Server to write PID file.
279 Added option -D to put Generic Frontend Server in background on its own.
281 Make ZOOM C recognize option "password". If unset, "pass" is used
282 (for backwards compatibility).
284 Fixed a bug in Generic Frontend Server that could make it crash if a
285 client sets characterSetNegotation bit, but didn't pass negotiation stuff
288 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
289 Must be issued before open, in order to be in effect.
291 --- 2.0.9-6 2004/01/12 Debian/Windows
293 Make the SRU server more picky WRT unknown params, etc.
295 Bug fix: ZOOM scan response didn't return displayTerm - when present.
297 New YAZ client command, options, that sets Z39.50 options.
299 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
300 options from a string of tokens (one token for each option bit).
302 Update SRW diagnostic code messages.
304 --- 2.0.9-5 2004/01/07 Debian/Windows
306 Handle user defined stylesheet for SRW/SRU.
308 --- 2.0.9-4 2004/01/06 Debian/Windows
310 Fix bug in decoding of Content-Length.
312 --- 2.0.9-3 2004/01/06 Debian/Windows
314 Fix a bug with decoding of XML packed records.
316 --- 2.0.9-2 2004/01/05 Debian only
318 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
320 Fix bug in SRW/SRU diagnostics decoding.
324 Fixed bug in Generic Frontend Server which could drop records exceeding
325 preferred message size. Reported and fixed by Irina Dijour.
327 Fixed calculation of package size for structured records in Generic
328 Frontend Server. Reported and fixed by Irina Dijour.
330 Fixed namespace for SRW/SRU diagnostics.
332 Fixed SEGV in yaz-client that occured for HTTP connection errors.
336 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
337 this version is incompatible with version 1.0 and older YAZ SRW/SRU
340 CQL changes to reflect recent changes to the specification:
341 * Documentation talks about context sets instead of index sets.
342 * Documentation talks about indexes instead of qualifiers.
343 * The CQL-to-PQF transformer's configuration file now uses
344 "index.set.name = <attributes>" instead of the old form
345 "qualifier.set.name = <attributes>". (Both forms are still
346 understood but the latter is deprecated.)
347 * CQL terms with no explicit index specified are now interpreted as
348 cql.serverChoice instead of srw.serverChoice (which of course
349 behaves exactly the same.)
353 MARC conversion can now generate ISO2709 output in another
354 character set. yaz-marcdump uses this facility if you invoke it
357 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
358 functions from there can be used from C++.
362 Frontend server now transfers memory from decoded packages to stream
365 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
366 references to show up.
368 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
369 the ZOOM Abstract API. The older names for the same options are still
370 also supported for the benefit of old applications.
372 ZOOM-C supports "implementationId" and "implementationVersion" options
373 to go along with "implementationName". These allow the user code to
374 specify identification strings to be sent to servers.
375 Add OID for the new ExtLite attribute set.
377 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
378 as requested/supplid by Ere Maijala <ere@atp.fi>
380 For generic frontend server, reverse the order of
381 "toolkit-supplied / application-supplied" strings sent as implementationId,
382 Name and Version. Also, remove the spaces around the slash. This brings
383 the GFS in line with the behaviour of ZOOM-C on the client side.
385 Add function ZOOM_scanset_display_term.
387 yaz-client shows scan displayTerm if present.
389 Utility yaz-iconv is now installed by default along with the man page
392 Extend configure check for OpenSSL to use pkg-config where available (such
395 Incorporate patch by Morten Bogeskov which allows a Unix file socket
396 server to specify uid/gid/mask for socket using the format
397 unix:[user=uid,][group=gid,][umask=mask,]file=path
398 If file= is omitted the existing format is assumed, e.g.
400 in which case the mask is 0666 (rw for everybody).
402 Major restructure of YAZ source. All source in libyaz is in src directory.
403 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
404 util (utility programs such as ASN.1 compiler, yaz-marcdump).
406 Added man page for utility yaz-marcdump (used to be called marcdump).
407 yaz-marcdump is installed by 'make install'.
409 Fixed a memory leak in Generic Frontend Server that occurred when decoding
410 of incoming package failed.
412 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
414 Change prototype of odr_perror: add const to message string.
416 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
418 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
419 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
420 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
421 DNS lookup. There should not be any compatibility problems with this
422 assuming that blocking=1 or 0 is used.
424 Fix bad reference in UNIX comstack in function cs_addrstr.
426 Fix for compilation on AIX.
428 The generic front-end server (server/seshigh.c) now supports returning
429 Init diagnostics to the client in User-information-field, in
430 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
435 Allow any CQL relation (not just all,any,exact,scr).
437 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
438 that features the same UI.
440 Implemented command update0 in YAZ client which is equivalent to
441 update but uses old of Ext Update ASN.1.
443 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
444 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
445 Previously no OID was used for this info.
447 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
448 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
449 returns 'malformed search term' otherwise.
451 SortResponse member resultCount now set to NULL in sort handler of
454 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
457 Add three new utility functions for translating OIDs between various
458 formats -- symbolic name such as "Usmarc", minus-1-terminated int
459 arrays and dotted strings such as "1.2.840.10003.9.5.1":
460 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
461 char *oid_to_dotstring(const int *oid, char *oidbuf);
462 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
464 Reverted modifications for ES Update definition for z_IU0Update
465 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
466 is back to YAZ 2.0.2.
468 String value attributes for CCL parser.
470 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
471 which their FirstSearch server returns in Init responses, sometimes
472 carrying useful diagnostic information when Init fails. This has the
473 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
474 "z39.50/oclcui.asn", where its definition is somewhat different from
475 what OCLC document on their web-site, as required to interoperate with
478 Support for anonymous authentication in yaz-client. Use the command
481 * Fix the OID of the Index Data-local "admin" Extended Service from
482 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
483 the 1000, which indicates a locally-defined OID, was a mistake.
487 Fix CCL directive @case handling so that it affects string match for
488 both CCL keywords and qualifiers.
490 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
491 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
492 Decoder has been updated with ASN.1 changes as listed in
493 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
494 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
495 z_IUUpdate, remains unchanged.
497 ZOOM_record_get may now return a record in a specific character set.
498 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
499 "from" is the character set of record as returned by target. "to" is
500 the character set to be returned. If omitted, "to" is UTF-8.
502 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
504 New ODR utility, odr_getelement, which returns name of element for
505 which encoding/decoding failed.
507 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
508 in cases where a required element was omitted.
510 Bug fix: some MARC8 sequences were not converted.
512 New ZOOM option "step" which specifies number of records to be
513 retrieved in one chunk. Used in conjunction with "start" and "count".
515 SRW support for yaz-client. Use scheme http: to use it, e.g.
518 yaz-client no longer does (un)intelligent character set conversions
519 by default. Can be enabled with charset and marc_charset commands.
521 xmalloc trace fix for 64-bit systems such as DEC alpha.
523 Solaris 2.6 compile fix.
525 New function, cql_strerror() translates SRW error codes, as returned
526 by cql_transform_error(), into human-readable English strings. Used
527 in yaz-client diagnostics when appropriate.
529 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
530 converts it into a type-1 query which is sent to the server. This
531 makes CQL available for use with all Z-servers, as opposed to the tiny
532 minority that can handle CQL queries themselves.
536 New Debian package layout similar to the Redhat Package layout.
538 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
539 and search result respectively.
543 Redhat package is now several packages: libyaz (runtime libraries),
544 libyaz-devel (development and documentation, and yaz (utility programs).
545 Package spec file by Morten Bøgeskov.
547 New member 'schema' in struct bend_fetch_rr which the name of requested
548 schema (SRW/SRU) for record (or NULL if none was given). The fetch
549 handler MAY set this to reflect the schema of the returned record.
551 New member 'display_term' in struct scan_entry. GFS now sets member entries
552 and allocates scan entries to be filled by user scan handler. In previous
553 version, entries member was allocated by the scan handler. That still works,
554 but the GFS will ignore member display_term - assuming it was NOT set by
555 the handler. The fact that the GFS now allocates the entries both allows
556 for new members and makes a scan handler easier to write.
558 Fix CQL lex buffer overflow.
560 SRW/SRU recordPacking. For SRW default recordPacking is string. For
561 SRU default recordPacking is string.
563 SRU protocol support for frontend server.
565 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
567 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
569 Added scan for the ZOOM shell (zoomsh).
573 * String Identifers for Schemas (Amendment 5).
574 http://lcweb.loc.gov/z3950/agency/amend/am5.html
575 Old definition for schema
576 Odr_oid *schema; /* OPT */
581 Z_InternationalString *uri;
582 #define Z_Schema_oid 1
583 #define Z_Schema_uri 2
586 * resultCount parameter to Sort Response (Amendment 1).
587 http://lcweb.loc.gov/z3950/agency/amend/am1.html
589 Support for SRW 1.0 over HTTP. This is an optional feature and
590 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
593 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
594 on the same port. SRW SearchRetrieveRequests are mapped
595 to bend_init,bend_search,bend_fetch,bend_close.
597 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
599 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
600 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
602 ZOOM connections are SRW based if schem http is used for hostname
603 in connect, e.g. z = ZOOM_connection_new("http://myserver");
604 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
606 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
607 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
608 distance=n, order=true/false, relation=le, prox unit=word. If
609 n is omitted, distance 1 is used.
611 Fixed problem with C compiler include path in wrong order.
613 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
614 on Solaris. Patch from Ko van der Sloot.
616 New MARC decode API. All new functions operate on a yaz_marc_t
617 handle. The most important new functions are: yaz_marc_create,
618 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
619 decode and destroy respectively. Decoder can produce formats
620 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
621 include/yaz/marcdisp.h.
623 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
624 to UTF-8, UCS-32, wchar_t or Latin-1.
626 * Prototypes for yaz_iconv_-functions moved to separate header
627 include/yaz/yaz-iconv.h.
629 Make a few private functions 'static' in unix.c. This prevents
630 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
632 For ZOOM connection, the options targetImplementation{Id,Name,Version}
633 are set when Init Response is received.
635 New function ZOOM_connection_error_x similar to ZOOM_connection_error
636 but returns diagnostic set as well.
638 New function yaz_strerror which is a portable wrapper for
639 strerror/strerror_r/GetLastMessage.
641 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
642 is returned for MARC. If type is "oai", then OAI MARC is returned.
644 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
649 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
651 Fix bad race conditions on SIGTERM and terminate gracefully in
654 Move retrieval (data1) module to Zebra since nobody seems to be
657 Add GRS-1 render for ZOOM using same format as yaz-client.
661 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
663 Fix broken ESpec handling in data1 module.
665 SGML reader parses comments and makes them part of the data1 tree.
667 Added several type casts so that YAZ compiles as C++ code.
669 ZOOM didn't handle PDU encoding failures properly.
671 Added more Bib-1 diagnostics (approved extensions).
673 GNU configure: better check for iconv.
675 More portable use of accept, getpeername. Check for socklen_t. Use
676 int/size_t if socklen_t is not defined.
680 PQF parser rejects bad queries - including those with extra
681 characters in them. PQF parser used to silently ignore that.
682 Cleaner API for PQF added, which allows you to get detailed
683 error information for bad queries (see yaz/pquery.h).
685 Fixed bug in ZOOM_record_get for type "database".
687 Implemented mini iconv library supporting conversions between
688 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
690 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
694 Fixed ZOOM C record cache so that preferredRecordSyntax and
695 elementSetName is used to check for already fetched records.
699 Added three members in bend_initrequest structure to facilitate
700 character set negotiation.
702 Fixed a bug in frontend server that could cause indefinite
703 loops under rare conditions.
705 Revised character set utilities (charneg.h) so that encoding
706 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
708 For PQF, directive @term <type> sets term type for Scan/Search.
709 Here <type> is general, string, numeric, null. The term type
710 is inherited - just like @attr.
712 New call odr_set_charset that sets character set conversion for
713 international-strings on a ODR stream. Prototype is:
714 int odr_set_charset(ODR o, const char *to, const char *from);
715 The InternationalString is still represented as C string in YAZ
716 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
717 won't). On the protocol level, you can use any encoding.
719 Support for UNIX sockets in ZOOM.
721 Solaris recv sometimes returns errno == ENOENT. It is treated as
722 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
724 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
725 both client and server. Code by Morten Bøgeskov.
729 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
730 that they can be used directly from Visual Basic. You must recompile
731 your windows APP if you're using ZOOM.
733 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
734 Commands "lang" and "charset" sets language and character set respectively.
735 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
736 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
738 Attributes from multiple CCL fields may be OR'ed rather than merged
739 using directive "@field or". Fields are still merged by default -
740 equivalent to "@field merge".
742 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
745 Fixed bug in zget for parameter ExtendedServicesResponse.
751 Added PQF feature: '@attr type=value' may be written as '@type=value'.
753 Client displays USR.1:SearchResult-1 (hits per term).
755 Additional Search Info for search in Generic Frontend Server.
757 Fixed CCL parsing of "field=s".
759 WIN32 installer - using the excellent NSIS software from nullsoft.
761 Fixed CCL parsing of "field = - <number>".
763 Added function yaz_marc_decode that decodes MARC for line mode
764 display or XML (similar to that used by JZKit).
766 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
767 Z39.50. But ISO/ILL was, however.
769 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
770 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
772 http://lcweb.loc.gov/z3950/agency/amend/am2.html
773 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
777 New YAZ client features: Command completion and new commands:
778 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
779 Code provided by Jacob Poulsen.
781 New call oid_trav, that visits all registered OIDs via callback.
783 Function ZOOM_record_get now returns const char pointer rather than
784 void pointer. It saves a lot of type casts.
786 For YAZ client, command "auth" now allows you to set authentication
787 in IdPass style. It is enabled when three tokens are given - order
788 is user, group and password.
790 Fix memory leaks in MARC record handling for ZOOM.
792 New option for YAZ client, -k <kilobytes> that sets
793 maximum record size. Similar to -k option for generic frontend
794 server and yaz-ztest.
796 More fixes for scan. Non-zero stepSize handled. OID's fixes.
798 Prefix query parser reports "fail" when bad attribute set is given.
800 Fix in MARC decoder. Proximity logging. Fix for attribute set
801 in scan handler for server. Patches by Shigeru Ishida.
803 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
806 Configure option --with-openssl=<dir> now works when a directory is
807 specified. Patch provided by Morten Bøgeskov.
809 New option for YAZ client, -u <auth>, that sets authentication.
811 ZOOM fix: error information was sometimes "missing", since error
812 was cleared/reset too when it shouldn't.
814 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
818 Scan for ZOOM API. New object ZOOM_scanset. New functions
819 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
820 ZOOM_scanset_destroy.
822 New ZOOM function, ZOOM_connection_last_event, that returns type
823 of last event (such as "receive data", "send data", "apdu received",
826 New ZOOM option, schema, that specifies schema for retrieval.
828 New CCL feature. Qualifiers can be aliases for one or more
829 other qualifiers (if more than one is given, OR is used).
831 ZOOM uses named result sets if target supports it.
833 Two new YAZ client commands: . (dot, which sources a script of YAZ
834 client commands), and ! (to execute shell command.). Implemented
837 Working on Debian packages.
841 YAZ client enables named result sets only if target supports it.
843 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
845 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
846 with key="host" to get same result.
848 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
849 Function Z3950_resultset_record(s) returns references to records
850 "owned" by resultset. To become owner use Z3950_record_clone.
852 Function z_ext_record handles Extended Services. Thanks to
857 CCL Parser fix: ignore token comma when dealing with and-lists.
859 Documentation updates for COMSTACK.
861 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
862 Changed prototype Z3950_records. For some functions, int parameters
863 were changed to size_t.
865 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
868 New MARC decode/display function, marc_display_exl, which properly rejects
869 non-ISO2709 records. YAZ client uses it.
873 Fix bug: local attribute set wasn't set correctly in PQF strings.
877 * Old Z39.50 codecs no longer supported.
879 Added ZOOM C binding. See http://zoom.z3950.org/
881 Renamed states for COMSTACKs to avoid confusion with events.
883 Implemented cs_look and proper cs_rcvconnect.
885 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
887 Configure detects POSIX threads on OpenBSD.
889 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
890 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
892 When error is returned from present handler, non-surrogate diagnostic
893 is returned in present response (and fetch handler is no longer called).
895 * Minor adjustments to pquery parser (PQF). Token characters may be
896 escaped by using backslash (C-style).
898 PQF parser allows string attribute values to be specified. For @attr,
899 non-numeric characters after the equal-sign are treated as strings
900 (e.g. @attr 9=title).
902 CCL trunction character may be defined (@truncation in file)
904 * function zget_ExtendedServicesRequest sets waitAction to
905 waitIfPossible (was wait).
907 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
910 CCL operator names may be set in field definition files (CCL_bibset).
911 See ccl/bib1 for an example.
913 Fixes in ASN.1 compiler for C++ compatibility.
915 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
916 and "op_or" to avoid conflict with C++.
918 Fixed problem with GNU readline detection on Redhat 7.0.
920 Added step-size for Scan backend handler.
922 Fixed bug that made the frontend server crash when no attribute
923 set was specified for scan.
925 Front-end server automatically switches to original working directory
926 when installed as an NT service. Previously -w had to be specified to
929 Added extended attributes for retrieval module (data1), so that data1
930 records carry d1_readXML/SGML attributes. d1_read also supports
931 null-data rules ( <tag/>)
933 On UNIX when POSIX threads are available, a separate library libyazthread
934 is created. Programmers should link with that library and the yaz library
935 when using threads. The reason for the split was that some applications
936 on Linux, such as Apache, doesn't work well when using shared objects that
939 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
940 (or any frontend server) in SSL mode by specifying ssl: followed by
941 address. Only tested on UNIX.
943 Added feature for CCL module. Virtual structure s=al or s=ol generates
944 and-list and or-list respectively instead of phrase search.
948 * Added prefix "yaz_" for the functions log_init.., log_file.. and
949 log_mask_str. This was done to avoid name conflicts with other libraries
950 (such as other PHP extensions).
952 Added raw OID member for preferred record syntax (request_format_raw)
953 and returned record syntax (output_format_raw) for backend fetch method.
955 Config file yaz-config now accepts options so that it returns specific
956 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
958 Shared library support for UNIX using GNU libtool.
960 * Modified backend interface. Request/Response struct's replaced by
961 one read/write C struct. For example bend_fetchrequest and
962 bend_fetchresult have been replaced by single bend_fetch_rr struct.
963 Every handler - even search has to be registered in bend_init
964 handler. This means that the YAZ library no longer refers to
965 external functions and it makes it possible to make the whole
966 thing a single DLL/SO.
968 Added Segment handler for backend server.
970 Added Zmbol/Zebra administrative functions to YAZ client.
972 Threaded frontend server on UNIX (when POSIX Threads are available).
973 Starting the server with option -T enables multi-threading.
977 Added configure option --enable-comp/disable-comp to control use
978 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
979 located in sub directory asn.
981 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
982 in ${exec_prefix}/bin along with the other programs yaz-client and
985 GNU automake used to maintain makefiles.
989 Changed retrieval module so that we can load records with no abstract
990 syntax defined. Tagpaths in these records are fully composed of string
993 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
997 On UNIX, the generated makefile now supports a proper 'make install'.
998 The prefix can be set via GNU configure to set the install location
999 (default is /usr/local).
1001 * YAZ programs client and ztest were renamed to yaz-client and
1002 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1003 locations, such as /usr/bin,/usr/local/bin,etc.
1005 * YAZ Header files were moved from include to include/yaz. YAZ Header
1006 files are referred to as include <yaz/log.h> rather than <log.h>.
1007 The YAZ include path (-I ..) is therefore the same as before. Programmers
1008 should update their #include statements or use -Ipath/include/yaz
1009 instead. The main motivation for doing this change is that YAZ header files
1010 can be installed in "standard" locations /usr/include,/usr/local/include
1011 without introducing conflicts, since ALL YAZ header files are stored
1012 in subdirectory yaz (under /usr/include for example).
1014 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1015 rather than project/workspace files. We switched because project files
1016 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1019 Changed name of logging function, logf, to yaz_log, to prevent name
1020 clash with some math-log functions. The YAZ header log.h defines logf
1021 to yaz_log (#define) so there should be no incompatibilities by this
1024 Added bend_start/bend_stop handlers for server. These handler are
1025 called on start/stop of server. For windows they are called whenever
1026 a service is started/stopped.
1028 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1029 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1030 in util/yc.tcl. The auto-generated C code structures are, in a few
1031 cases, incompatible with the old decoders. There are differences in the
1032 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1033 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1034 The preprocessor variable ASN_COMPILED is defined when the compiled
1035 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1036 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1037 wish to use the old encoders/decoders you can specify --disable-yc
1040 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1041 version so that it supports both new - and old version of DB Update
1043 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1044 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1045 change. The name parameter can be set to 0 in which no name is specified
1046 for the construction. The macros odr_implicit and odr_explicit sets name
1047 parameter to zero for the construction involved. New macros
1048 odr_implicit_tag and odr_explicit_tag are similar to the others,
1049 except that a name parameter is added. For programmers' that don't use
1050 ODR they probably only need to change the call to z_APDU and z_External.
1052 Added access control facility by interfacing the TCP wrapper library.
1053 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1054 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1055 name of the daemon and enables the access control as specified in
1056 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1058 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1059 den Dool <H.M.vdnDool@kub.nl>.
1061 Added reference ID parameter to most functions in server API - refer
1062 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1064 Changed name of ccl library to libccl.a (was ccl.a).
1066 Fixed bug in decoder for Explain (Category TargetInfo).
1068 Added support for GNU readline in client. Thanks to Jacob Poulsen
1069 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1071 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1072 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1073 IMPLEMENTATION! This change was made to the development version before
1074 the ZIG decided to retract the amendment. If any users MUST be
1075 compatible with the original Update definition, PLEASE CONTACT US, and
1076 we will include a separate definition corresponding to the old Update
1077 ES. Note that because of the change to the ASN.1 of the
1078 TaskPackageRecordStructure we cannot define a single structure that
1079 will support both versions.
1081 * Added const modifier to buffer parameter for some ODR/BER encoding
1082 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1083 completeWAIS, odr_dumpBER.
1085 Fixed bug in client.c which caused a crash when a scanResponse didn't
1086 contain positionOfTerm.
1088 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1089 * will cause an error in a client if a non-YAZ target sends both a
1090 * list of Scan entries and non-surrogate diagnostics.
1092 Retrieval module enhancements. Tag sets may be typed in the reference
1093 to it. From the .abs-file the "tagset" directive takes a third optional
1094 integer type for the tag set referenced. From a .tag-file the "include"
1095 directive takes a third optional type as well. The old "type" directive
1096 in the tag set itself is still recognized but acts as the default type
1099 Backend interface change. Individual Scan terms returned from bend_scan
1100 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1101 in include/backend.h.
1103 Retrieval module enhancements. Multiple tag sets and attribute sets may
1104 be specified in abstract syntax specs. Revised the error/warning for
1105 logging messages reported by the retrieval module when reading the
1108 Object Identifier system (oid_..) changed. The API is backwards
1109 compatible but the oid-routines now allocates new OID's when needed.
1110 Raw OID's may be specified in oid_getvalbyname.
1112 YAZ now uses GNU configure to generate Makefile(s).
1114 * Minor changes in some of the member names of DeleteResultSetRequest and
1115 DeleteResultSetResponse. See include/proto.h.
1117 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1118 and added member 'languages' in TargetInfo (which was missing).
1120 Changed the way attribute sets are handled in the retrieval
1121 module. These are now cached, just like the abstract syntaxes
1124 Changed YAZ so that it links with compiled ASN.1.
1126 Added Explain-schema definitions and mapping routines. The following
1127 Explain categories have been implemented: AttributeDetails,
1128 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1130 Fixed minor bug in Windows version of Server Library.
1132 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1134 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1136 Added EXTERNAL: UNIverse Resource Report (non-standard).
1138 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1139 ENUMERATED and SET OF.
1141 * Added 'const' to some of the char pointer arguments for the
1142 functions, data1_read_node, data1_getelementbytagname,
1143 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1146 Fixed bug in data1_insert_taggeddata - the last_child member of
1147 parent wasn't initialised.
1149 * Changed data1_read_record and data1_read_node so that the supplied
1150 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1151 doesn't refer to any parts of the "SGML"-buffer.
1153 Fixed bug in server library (Windows version of statserv_remove).
1155 * Changed code so that it compiles as C++. The type definition
1156 of Odr_fun which is a member of Odr_arm was changed. The result is,
1157 that an explicit typecast is needed for the fun pointer when
1158 using Odr_arm - as in:
1159 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1161 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1163 Implemented the new structured date and time definition as approved
1164 by the ZIG. Added schemaId element to the specificTag in Espec-1
1165 (also approved at the last ZIG). Thanks to RVDM.
1167 Added some Object identifiers (RVDM).
1169 Changed the Update Extended Service (RVDM).
1171 Added command "refid" to client which specifies referenceId for
1172 the following requests.
1174 Implemented extended service handling for server. See ztest.c
1175 for an example as well as backend.h. New handlers are registerd
1176 in the Init handler.
1178 * Changed interface for sort in server.
1180 Added new members to statserv_options_block. It allows a server
1181 to read options from another source than just the command line. Thanks
1182 to Charles Woodfield.
1184 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1185 renamed to zboolean. Some C++ compilers complained about the name.
1187 Minor changes to gils.abs. Added index 's' (sort) on title
1188 and date/time-last-modified.
1190 --- 1.4pl2 1998/1/30
1192 Fixed bug in server library regarding inetd mode (-i). This bug
1193 was introduced by release 1.4.
1195 --- 1.4pl1 1998/1/29
1197 Added sort facility in client and backend server interface.
1199 Fixed problem with dependencies in Makefile(s).
1201 Fixed bugs for encoders/decoders of extended services and
1204 Implemented sub-tree feature for schemas. Sub-trees are
1205 referenced in *.abs-files. See explain.abs for an example
1206 of the use of this feature.
1208 Modified bib1.att; local attributes for ANY didn't include
1209 ANY itself (only affects use of the retrieval module).
1211 Fixed bug in plain SGML reader in function data1_read_node:
1212 tags with prefix "var" was incorrectly interpreted as variants.
1214 Added feature "sub-schemas" to enable references to - and definitions
1215 of - group of elements.
1217 * Removed member parent from type data1_element (in data1.h).
1219 Implemented function odr_nullval() that returns the value of
1222 * Removed member num_children from data1_node (in data1.h).
1224 Made NT service interface part of the server library. The
1225 function statserv_main uses the NT service when required and
1226 calls the statserv_start / statserv_close routines.
1228 Routine zget_SearchRequest and zget_PresentRequest fills
1229 resultSetName/Id member with "default" instead of "Default".
1231 Fixed memory leak in server. Request queue member wasn't freed.
1233 Fixed nmem_exit so that memory is freed.
1237 Revised the CCL parser utility to be thread safe.
1239 Added function, oid_ent_to_oid, to replace the function
1240 oid_getoidbyent, which is not thread safe.
1242 * Added nmem_init and nmem_exit to initialize and release
1243 NMEM resources. Function nmem_init should be called once in the
1244 initial thread before NMEM/ODR is used. statserv.c and client.c
1245 have been changed accordingly. The change was necessary to make
1246 NMEM thread safe. The NMEM memory pool is shared amongst threads
1247 in a process. Unix-based applications will still work fine without
1250 Added NT Services interface for the the Z39.50 (statserv) Server.
1251 Refer to the ztest.c source on the usage.
1253 Windows 95/NT port using MSVC5.0. Project files are included in the
1256 * Defined new 'global' handle for the retrieval (data1) system. The
1257 new handled, data1_handle, describes the state of the data1 system.
1258 This handle is passed as first argument to virtually all
1259 data1 related routines. The functions data1_create and data1_destroy
1260 creates and destroys a data1 handle respectively.
1262 Added ODR encode stream member to all backend request structures
1263 init, search, scan etc. This stream should be used to allocate all
1264 memory used for the response when thread safe operation is needed.
1266 Changed the comstack utility, cs_addstr, to be thread safe. The
1267 returned hostname string returned by the function is now part the
1270 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1271 function. The cs_straddr takes a COMSTACK handle as argument, so this
1272 function must be used after cs_create and before bind/connect.
1273 This function is thread safe.
1275 Moved test server to 'ztest' directory - generic server code still
1276 in 'server' directory.
1278 Made prefix query (pquery.c) utility thread safe.
1280 Added new function modifier YAZ_EXPORT to 'export' public DLL
1281 functions when using windows (see include/yconfig.h).
1283 Added definitions to the OID database (util/oid.c) (RVDM).
1285 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1287 Added call to ccl_rpn_delete in client program.
1289 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1290 release of RPN structure.
1292 Added support for C++, headers uses extern "C" for public definitions.
1293 With input from RVDM.
1295 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1296 Thanks to Ronald van der Meer (RVDM).
1298 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1300 Added support for private extensions to the OID database
1301 (oid_setprivateoids()). Thanks to RVDM.
1303 Added optional, physical ANY (key replication)
1305 Fixed null-reference problem in GRS-1 output filter.
1307 Proximity operator added to Prefix Query Format (PQF).
1309 In test client command "base" accepts multiple databases.
1311 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1315 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1317 Smallish bug-fixes in the new encoders/decoders (explain).

1327 Added Update extended service.
1329 Added SearchResult-1 additional info structure.

1334 --- 1.2 1996/6/10 (1st anniversary release)
1336 Added Summary record syntax. Lightly tested.
1338 Added OPAC record syntax. Untested.

1346 Added options for max PDU size and session timeout to frontend-server.
1348 Added documentation of query-language parsers and other supporting utilities.
1350 [frontend-server] Added Attribute set to the bend_scanrequest API.
1352 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1353 surrogate diagnostics were generated.
1355 [retrieval] Allow multiple local values for attribute.
1357 [retrieval] Allow multiple attributes per element in .abs files. index type.
1359 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1361 --- 1.1pl2 1996/4/10
1363 Minor changes, mostly specific to Zebra's requirements (retrieval)
1367 Repaired bug in frontend server when running multiple listening
1368 endpoints in dynamic mode.
1370 z_External() now won't break if a known, ASN.1 value comes encapsulated
1371 in an octet-string. The value will pass through unmodified in an Odr_oct.
1373 Added a bit of code to the demo client to decode & display
1374 ASN.1-structured records represented in the octet-aligned branch of
1375 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1377 Added z_ext_getentbyref() to the ASN module. Doc updated.
1379 * Completed the SCAN definition in the ASN module. This may break SCAN
1380 code based on older YAZ-versions at compile-time. The fix is easy -
1383 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1384 under the SCAN definition. Remember to initialize this, server-people.
1386 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1387 that this does not extend to ODR and ASN.
1389 Comstack allows insertion of established socket (primarily for
1390 inetd-operation of servers). Doc updated.
1392 Front-end server can now start from the inetd in TCP mode. Doc
1395 --- 1.0pl4 1996/1/24
1399 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1400 the rank and record number.
1402 Adjustments to the frontend server.
1404 Fixed diagnostic BER dumper. It ignored the file argument.
1408 Various changes to retrieval module.
1410 Changed the union discriminators of the protocol files from enums to
1411 ints paired with #defines.
1413 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1416 *Changed operator in the RPN structure to 'roperator', again to avoid a
1419 Fixed problems in Explain decoders/encoders.
1421 --- 1.0pl2 1995/12/6
1423 Memory bug in log module fixed.
1425 --- 1.0pl1 1995/12/5
1427 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1429 Bug in Explain DatabaseInfo module fixed.
1431 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1435 The shift to v1.0 signals that we now consider the *core* functionality
1436 of YAZ reasonably stable (the core being more or less equivalent to
1437 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1438 tested (Explain not at all - though that will happen soonish).
1440 Minor changes to code to support Windows port.
1442 Various minor changes after we're getting to use GRS-1 & co. more.
1444 Added Espec-1 format.
1446 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1447 of the protocol and it cannot be selected when encoding (maps into 'string'
1448 when decoding). Needed to talk to some servers.
1450 Demo client can request simple element set names.
1452 Added Diagnostic Format encoders/decoders.
1454 Added simple Close handling to frontend server (no hooks for resource
1455 reporting yet), and demonstration client.
1457 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1459 --- 1.0b3 1995/08/24
1461 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1462 handled incorrectly when records were requested in the searchResponse. This
1463 will only affect you if you use the frontend-server.
1465 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1466 Test-client will ask for and print GRS1. Ztest will return dummy records
1469 Added Explain encoders/decoders to the service-level API. Untested.
1471 Added Extended Services: Item Order encoders and decoders to the Service-
1472 level API. Untested. We could use a recent copy of the pertinent bits
1473 of the ILL protocol to add those bits.
1475 Added diagnostic format 1 encoders/decoders to the service-level API.
1478 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1479 odr_cons.c, which causes a more correct output.
1481 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1482 was always set to 0 when no records were requested in the searchRequest.
1484 * Added better external-handling. This shouldn't harm old code that
1485 *encodes* externals. It can break code that looks for a
1486 'single-ASN1-type' representation, since those types that are known
1487 are now decoded immediately. Look at the SUTRS sample code in
1488 seshigh.c and client.c. Documentation updated.
1490 Handling of structured records in bend_fetchresponse. Length -1 marks
1491 structured record, type is deduced from format field.
1493 --- 1.0b2 1995/06/27
1494 Fairly quick maintenance release to add SUTRS support.
1496 Fixed handling of SUTRS records in the demonstration client.
1498 * Added format field to the bend_fetchrequest and bend_fetchresponce
1499 structures of the backend API (frontend server). When the record is
1500 returned, the value of the format field is mapped to an OID. The
1501 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1502 of the record. The special value VAL_NONE in the bend_request means
1503 that no specific format was requested by the client. Documentation
1504 updated accordingly. Test server (ztest) will return a fixed dummy
1505 SUTRS record if your client requests SUTRS.
1507 Documentation updated accordingly.
1509 You can now set external libraries and RANLIB support in the top-level
1513 First public release.
