1 Possible compatibility problems with earlier versions marked with '*'.
3 Added support for virtual hosts and multiple backend servers for
4 the YAZ frontend server. The configution is XML based and
5 support specificition of CQL to RPN mappings and explain information.
6 See section "Virtual Hosts" in the YAZ manual.
8 Extended OPAC display utility. OPAC display utility renders
9 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
10 to supplement yaz_marc_decode_wrbuf.
14 Fixes for UNIX domain sockets. Bug #261.
16 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
18 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
19 Added yaz_marc_subfield_str which defines subfield lead string which is
20 used in YAZ_MARC_LINE format. Default string is blank+$. Added
21 yaz_marc_endline_str which defines end of fields string used in
22 YAZ_MARC_LINE format. Default string is newline.
24 Experimental support for MarcXChange. This format can be produced
25 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
26 http://www.bs.dk/standards/MarcXchange.xsd
28 Added yaz-client commands scansize that sets maximum number of
29 entries to be returned by scan.
33 Added support for SRW scan in yaz-client and Generic Frontend Server.
35 * Added whereInList member to SRW Scan Term.
37 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
39 Fixed NMEM system to return aligned blocks on the smallest boundaries
40 that are suitably aligned for all possible types on the particular
41 architecture YAZ is being built for.
45 Fixed numerious warnings that was issued with newer versions of GCC.
47 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
48 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
51 Make YAZ Generic Frontend Server slightly faster.
53 Enhance (and reduce) logging for Generic Frontend Server.
55 Revert YAZ log system so that it flushes every write operation
56 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
58 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
59 instead of LOG_, due to name clash with syslog(3). LOG_ are still
60 present. New applications should define YAZ_USE_NEW_LOG=1 - this
61 will effectively disable old definitions.
65 Added yaz_log_time_format which specifies log format using
68 Added yaz_log_module_level which returns mask for a module. Value
69 is non-zero mask a if module is enabled; zero if disabled.
71 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
74 Fixed bug #176: Dont throw diagnostics on empty SRU args.
76 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
78 Fixed bug #172: RPM builds does not enable SSL.
80 Doxyfile.in part of dist. Doxyfile generated by configure.
82 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
83 are given and the corresponding component does not exist.
85 Extend CCL documentation in YAZ reference. Describe r=r.
89 Fixed MARC->MARCXML conversion to properly deal with
90 fields, subfields, indicators having non-ASCII characters.
92 Fixed MARC->MARCXML conversion so that ASCII control characters
93 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
96 Added YAZ GFS support for conversion from Z39.50 surrogate
97 diagnostics to SRW surrogate diagnostics.
99 Bug fix: YAZ GFS did not return schema in explainResponse.
101 --- 2.0.25 2004/09/30
103 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
104 now converts recordSchema to elementSetName as well as schema URI.
106 Fixed bug in COMSTACK that prevented HTTP request packages from being
109 --- 2.0.24 2004/09/29
111 Added CCL facility r=r "range" which is similar to r=o "ordered" but
112 does not require white-space before and after the dash in a range, e.g.
113 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
116 Fixed a few AC_TRY_LINK configure tests that did not operate properly
117 due to new GCC removing "redundant" code.
119 Added yaz-client commands scanpos and scanstep that sets preferred
120 position and step-size for scan.
122 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
124 Added CCL utility ccl_qual_buf which parses one or more CCL
125 spec lines in a buffer.
127 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
128 of name and value - ignoring empty lines and comments.
130 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
132 Added odr_get_element_path which returns current element path for an
133 ODR handle. This utility is useful in error handling or user-defined
136 Added ODR_PRINT utility odr_set_stream which is is a more generic
137 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
138 to a write function and pointer to close function. The close function - if
139 non-NULL - will be called during odr_destroy.
141 Fixed bug in CCL parser where truncation char was not removed from
142 right side when truncation=both was in effect.
144 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
147 --- 2.0.23 2004/08/11
149 Fix buffer overrun in CQL parser when dealing with proximity (%).
151 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
152 to UTF-8/UCS conversion is now only based on codetables.xml.
154 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
156 --- 2.0.22 2004/08/06
158 Add support for more "commit changes" in ZOOM (uses Extended Services).
160 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
163 Yet another small fix for configure of SSL.
165 --- 2.0.21 2004/05/14
167 Fix SSL libs for configure when --with-openssl=DIR is given.
169 --- 2.0.20 2004/05/10
171 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
173 SSL comstack now uses yaz.pem certificate file on server side
174 by default. Certificate filename can be configured by calling
175 comstack function cs_set_ssl_certificate_file before cs_bind is used.
177 Fix bug regarding multiple calls to ZOOM_connection_connect.
179 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
181 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
182 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
184 ZOOM now allows inspection of X509 peer certificate for verification.
185 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
187 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
188 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
189 as "modular" but it simplifies things.
191 Added cs_get_peer_certificate to that returns peer X509 PEM.
193 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
194 NULL if SSL is unavailable.
196 Documentation about MARC decoding tools.
198 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
200 --- 2.0.19 2004/03/30
202 Rename CHANGELOG to NEWS to follow GNU style packing.
204 Fix bug with missing initialization of member in init_diagnostics.
205 This bug affects threaded version of GFS server.
207 --- 2.0.18 2004/03/20
209 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
212 Ensure zlib.dll is packed with Windows install.
214 --- 2.0.17 2004/03/17
216 Fix encoding of xsd:string to use text instead of CDATA.
218 Fix endless loop in CQL parser with unbalanced ".
220 Use a more compact way to store MARC-8 conversion tables.
222 --- 2.0.16 2004/03/16 Debian only
224 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
227 Update CQL parser to use new CQL 1.1 modifiers for booleans and
232 --- 2.0.15 2004/03/01
234 Another fix for decoding of XML packed records.
236 --- 2.0.14 2004/02/25
238 Fixes for Chunked encoding. White space not ignored after length spec.
240 Update NS and use default NS for SRW diagnostic elements.
242 --- 2.0.13 2004/02/23
244 Implement ZOOM_resultset_cache_reset which resets record cache.
246 Implement ZOOM_resultset_sort which sorts a result set.
248 Implement chunked HTTP transfer.
250 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
252 --- 2.0.12 2004/02/16
254 Added member 'schema' to bend_explain_rr structure so that backend
255 can specify explain record identifier. Defaults to Zeerex 2.0.
257 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
259 --- 2.0.11 2004/02/16
261 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
264 Added init command for yaz-client which sends "extra" init request.
266 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
267 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
269 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
271 Make ZOOM error code for "invalid query".
273 Fixed compilation for SSL which wasn't properly enabled for all platforms.
275 --- 2.0.10 2004/02/05
277 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
280 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
282 Added option -p <file> to make Generic Frontend Server to write PID file.
284 Added option -D to put Generic Frontend Server in background on its own.
286 Make ZOOM C recognize option "password". If unset, "pass" is used
287 (for backwards compatibility).
289 Fixed a bug in Generic Frontend Server that could make it crash if a
290 client sets characterSetNegotation bit, but didn't pass negotiation stuff
293 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
294 Must be issued before open, in order to be in effect.
296 --- 2.0.9-6 2004/01/12 Debian/Windows
298 Make the SRU server more picky WRT unknown params, etc.
300 Bug fix: ZOOM scan response didn't return displayTerm - when present.
302 New YAZ client command, options, that sets Z39.50 options.
304 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
305 options from a string of tokens (one token for each option bit).
307 Update SRW diagnostic code messages.
309 --- 2.0.9-5 2004/01/07 Debian/Windows
311 Handle user defined stylesheet for SRW/SRU.
313 --- 2.0.9-4 2004/01/06 Debian/Windows
315 Fix bug in decoding of Content-Length.
317 --- 2.0.9-3 2004/01/06 Debian/Windows
319 Fix a bug with decoding of XML packed records.
321 --- 2.0.9-2 2004/01/05 Debian only
323 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
325 Fix bug in SRW/SRU diagnostics decoding.
329 Fixed bug in Generic Frontend Server which could drop records exceeding
330 preferred message size. Reported and fixed by Irina Dijour.
332 Fixed calculation of package size for structured records in Generic
333 Frontend Server. Reported and fixed by Irina Dijour.
335 Fixed namespace for SRW/SRU diagnostics.
337 Fixed SEGV in yaz-client that occured for HTTP connection errors.
341 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
342 this version is incompatible with version 1.0 and older YAZ SRW/SRU
345 CQL changes to reflect recent changes to the specification:
346 * Documentation talks about context sets instead of index sets.
347 * Documentation talks about indexes instead of qualifiers.
348 * The CQL-to-PQF transformer's configuration file now uses
349 "index.set.name = <attributes>" instead of the old form
350 "qualifier.set.name = <attributes>". (Both forms are still
351 understood but the latter is deprecated.)
352 * CQL terms with no explicit index specified are now interpreted as
353 cql.serverChoice instead of srw.serverChoice (which of course
354 behaves exactly the same.)
358 MARC conversion can now generate ISO2709 output in another
359 character set. yaz-marcdump uses this facility if you invoke it
362 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
363 functions from there can be used from C++.
367 Frontend server now transfers memory from decoded packages to stream
370 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
371 references to show up.
373 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
374 the ZOOM Abstract API. The older names for the same options are still
375 also supported for the benefit of old applications.
377 ZOOM-C supports "implementationId" and "implementationVersion" options
378 to go along with "implementationName". These allow the user code to
379 specify identification strings to be sent to servers.
380 Add OID for the new ExtLite attribute set.
382 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
383 as requested/supplid by Ere Maijala <ere@atp.fi>
385 For generic frontend server, reverse the order of
386 "toolkit-supplied / application-supplied" strings sent as implementationId,
387 Name and Version. Also, remove the spaces around the slash. This brings
388 the GFS in line with the behaviour of ZOOM-C on the client side.
390 Add function ZOOM_scanset_display_term.
392 yaz-client shows scan displayTerm if present.
394 Utility yaz-iconv is now installed by default along with the man page
397 Extend configure check for OpenSSL to use pkg-config where available (such
400 Incorporate patch by Morten Bogeskov which allows a Unix file socket
401 server to specify uid/gid/mask for socket using the format
402 unix:[user=uid,][group=gid,][umask=mask,]file=path
403 If file= is omitted the existing format is assumed, e.g.
405 in which case the mask is 0666 (rw for everybody).
407 Major restructure of YAZ source. All source in libyaz is in src directory.
408 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
409 util (utility programs such as ASN.1 compiler, yaz-marcdump).
411 Added man page for utility yaz-marcdump (used to be called marcdump).
412 yaz-marcdump is installed by 'make install'.
414 Fixed a memory leak in Generic Frontend Server that occurred when decoding
415 of incoming package failed.
417 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
419 Change prototype of odr_perror: add const to message string.
421 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
423 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
424 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
425 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
426 DNS lookup. There should not be any compatibility problems with this
427 assuming that blocking=1 or 0 is used.
429 Fix bad reference in UNIX comstack in function cs_addrstr.
431 Fix for compilation on AIX.
433 The generic front-end server (server/seshigh.c) now supports returning
434 Init diagnostics to the client in User-information-field, in
435 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
440 Allow any CQL relation (not just all,any,exact,scr).
442 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
443 that features the same UI.
445 Implemented command update0 in YAZ client which is equivalent to
446 update but uses old of Ext Update ASN.1.
448 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
449 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
450 Previously no OID was used for this info.
452 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
453 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
454 returns 'malformed search term' otherwise.
456 SortResponse member resultCount now set to NULL in sort handler of
459 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
462 Add three new utility functions for translating OIDs between various
463 formats -- symbolic name such as "Usmarc", minus-1-terminated int
464 arrays and dotted strings such as "1.2.840.10003.9.5.1":
465 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
466 char *oid_to_dotstring(const int *oid, char *oidbuf);
467 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
469 Reverted modifications for ES Update definition for z_IU0Update
470 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
471 is back to YAZ 2.0.2.
473 String value attributes for CCL parser.
475 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
476 which their FirstSearch server returns in Init responses, sometimes
477 carrying useful diagnostic information when Init fails. This has the
478 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
479 "z39.50/oclcui.asn", where its definition is somewhat different from
480 what OCLC document on their web-site, as required to interoperate with
483 Support for anonymous authentication in yaz-client. Use the command
486 * Fix the OID of the Index Data-local "admin" Extended Service from
487 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
488 the 1000, which indicates a locally-defined OID, was a mistake.
492 Fix CCL directive @case handling so that it affects string match for
493 both CCL keywords and qualifiers.
495 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
496 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
497 Decoder has been updated with ASN.1 changes as listed in
498 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
499 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
500 z_IUUpdate, remains unchanged.
502 ZOOM_record_get may now return a record in a specific character set.
503 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
504 "from" is the character set of record as returned by target. "to" is
505 the character set to be returned. If omitted, "to" is UTF-8.
507 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
509 New ODR utility, odr_getelement, which returns name of element for
510 which encoding/decoding failed.
512 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
513 in cases where a required element was omitted.
515 Bug fix: some MARC8 sequences were not converted.
517 New ZOOM option "step" which specifies number of records to be
518 retrieved in one chunk. Used in conjunction with "start" and "count".
520 SRW support for yaz-client. Use scheme http: to use it, e.g.
523 yaz-client no longer does (un)intelligent character set conversions
524 by default. Can be enabled with charset and marc_charset commands.
526 xmalloc trace fix for 64-bit systems such as DEC alpha.
528 Solaris 2.6 compile fix.
530 New function, cql_strerror() translates SRW error codes, as returned
531 by cql_transform_error(), into human-readable English strings. Used
532 in yaz-client diagnostics when appropriate.
534 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
535 converts it into a type-1 query which is sent to the server. This
536 makes CQL available for use with all Z-servers, as opposed to the tiny
537 minority that can handle CQL queries themselves.
541 New Debian package layout similar to the Redhat Package layout.
543 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
544 and search result respectively.
548 Redhat package is now several packages: libyaz (runtime libraries),
549 libyaz-devel (development and documentation, and yaz (utility programs).
550 Package spec file by Morten Bøgeskov.
552 New member 'schema' in struct bend_fetch_rr which the name of requested
553 schema (SRW/SRU) for record (or NULL if none was given). The fetch
554 handler MAY set this to reflect the schema of the returned record.
556 New member 'display_term' in struct scan_entry. GFS now sets member entries
557 and allocates scan entries to be filled by user scan handler. In previous
558 version, entries member was allocated by the scan handler. That still works,
559 but the GFS will ignore member display_term - assuming it was NOT set by
560 the handler. The fact that the GFS now allocates the entries both allows
561 for new members and makes a scan handler easier to write.
563 Fix CQL lex buffer overflow.
565 SRW/SRU recordPacking. For SRW default recordPacking is string. For
566 SRU default recordPacking is string.
568 SRU protocol support for frontend server.
570 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
572 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
574 Added scan for the ZOOM shell (zoomsh).
578 * String Identifers for Schemas (Amendment 5).
579 http://lcweb.loc.gov/z3950/agency/amend/am5.html
580 Old definition for schema
581 Odr_oid *schema; /* OPT */
586 Z_InternationalString *uri;
587 #define Z_Schema_oid 1
588 #define Z_Schema_uri 2
591 * resultCount parameter to Sort Response (Amendment 1).
592 http://lcweb.loc.gov/z3950/agency/amend/am1.html
594 Support for SRW 1.0 over HTTP. This is an optional feature and
595 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
598 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
599 on the same port. SRW SearchRetrieveRequests are mapped
600 to bend_init,bend_search,bend_fetch,bend_close.
602 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
604 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
605 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
607 ZOOM connections are SRW based if schem http is used for hostname
608 in connect, e.g. z = ZOOM_connection_new("http://myserver");
609 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
611 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
612 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
613 distance=n, order=true/false, relation=le, prox unit=word. If
614 n is omitted, distance 1 is used.
616 Fixed problem with C compiler include path in wrong order.
618 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
619 on Solaris. Patch from Ko van der Sloot.
621 New MARC decode API. All new functions operate on a yaz_marc_t
622 handle. The most important new functions are: yaz_marc_create,
623 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
624 decode and destroy respectively. Decoder can produce formats
625 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
626 include/yaz/marcdisp.h.
628 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
629 to UTF-8, UCS-32, wchar_t or Latin-1.
631 * Prototypes for yaz_iconv_-functions moved to separate header
632 include/yaz/yaz-iconv.h.
634 Make a few private functions 'static' in unix.c. This prevents
635 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
637 For ZOOM connection, the options targetImplementation{Id,Name,Version}
638 are set when Init Response is received.
640 New function ZOOM_connection_error_x similar to ZOOM_connection_error
641 but returns diagnostic set as well.
643 New function yaz_strerror which is a portable wrapper for
644 strerror/strerror_r/GetLastMessage.
646 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
647 is returned for MARC. If type is "oai", then OAI MARC is returned.
649 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
654 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
656 Fix bad race conditions on SIGTERM and terminate gracefully in
659 Move retrieval (data1) module to Zebra since nobody seems to be
662 Add GRS-1 render for ZOOM using same format as yaz-client.
666 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
668 Fix broken ESpec handling in data1 module.
670 SGML reader parses comments and makes them part of the data1 tree.
672 Added several type casts so that YAZ compiles as C++ code.
674 ZOOM didn't handle PDU encoding failures properly.
676 Added more Bib-1 diagnostics (approved extensions).
678 GNU configure: better check for iconv.
680 More portable use of accept, getpeername. Check for socklen_t. Use
681 int/size_t if socklen_t is not defined.
685 PQF parser rejects bad queries - including those with extra
686 characters in them. PQF parser used to silently ignore that.
687 Cleaner API for PQF added, which allows you to get detailed
688 error information for bad queries (see yaz/pquery.h).
690 Fixed bug in ZOOM_record_get for type "database".
692 Implemented mini iconv library supporting conversions between
693 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
695 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
699 Fixed ZOOM C record cache so that preferredRecordSyntax and
700 elementSetName is used to check for already fetched records.
704 Added three members in bend_initrequest structure to facilitate
705 character set negotiation.
707 Fixed a bug in frontend server that could cause indefinite
708 loops under rare conditions.
710 Revised character set utilities (charneg.h) so that encoding
711 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
713 For PQF, directive @term <type> sets term type for Scan/Search.
714 Here <type> is general, string, numeric, null. The term type
715 is inherited - just like @attr.
717 New call odr_set_charset that sets character set conversion for
718 international-strings on a ODR stream. Prototype is:
719 int odr_set_charset(ODR o, const char *to, const char *from);
720 The InternationalString is still represented as C string in YAZ
721 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
722 won't). On the protocol level, you can use any encoding.
724 Support for UNIX sockets in ZOOM.
726 Solaris recv sometimes returns errno == ENOENT. It is treated as
727 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
729 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
730 both client and server. Code by Morten Bøgeskov.
734 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
735 that they can be used directly from Visual Basic. You must recompile
736 your windows APP if you're using ZOOM.
738 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
739 Commands "lang" and "charset" sets language and character set respectively.
740 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
741 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
743 Attributes from multiple CCL fields may be OR'ed rather than merged
744 using directive "@field or". Fields are still merged by default -
745 equivalent to "@field merge".
747 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
750 Fixed bug in zget for parameter ExtendedServicesResponse.
756 Added PQF feature: '@attr type=value' may be written as '@type=value'.
758 Client displays USR.1:SearchResult-1 (hits per term).
760 Additional Search Info for search in Generic Frontend Server.
762 Fixed CCL parsing of "field=s".
764 WIN32 installer - using the excellent NSIS software from nullsoft.
766 Fixed CCL parsing of "field = - <number>".
768 Added function yaz_marc_decode that decodes MARC for line mode
769 display or XML (similar to that used by JZKit).
771 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
772 Z39.50. But ISO/ILL was, however.
774 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
775 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
777 http://lcweb.loc.gov/z3950/agency/amend/am2.html
778 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
782 New YAZ client features: Command completion and new commands:
783 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
784 Code provided by Jacob Poulsen.
786 New call oid_trav, that visits all registered OIDs via callback.
788 Function ZOOM_record_get now returns const char pointer rather than
789 void pointer. It saves a lot of type casts.
791 For YAZ client, command "auth" now allows you to set authentication
792 in IdPass style. It is enabled when three tokens are given - order
793 is user, group and password.
795 Fix memory leaks in MARC record handling for ZOOM.
797 New option for YAZ client, -k <kilobytes> that sets
798 maximum record size. Similar to -k option for generic frontend
799 server and yaz-ztest.
801 More fixes for scan. Non-zero stepSize handled. OID's fixes.
803 Prefix query parser reports "fail" when bad attribute set is given.
805 Fix in MARC decoder. Proximity logging. Fix for attribute set
806 in scan handler for server. Patches by Shigeru Ishida.
808 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
811 Configure option --with-openssl=<dir> now works when a directory is
812 specified. Patch provided by Morten Bøgeskov.
814 New option for YAZ client, -u <auth>, that sets authentication.
816 ZOOM fix: error information was sometimes "missing", since error
817 was cleared/reset too when it shouldn't.
819 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
823 Scan for ZOOM API. New object ZOOM_scanset. New functions
824 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
825 ZOOM_scanset_destroy.
827 New ZOOM function, ZOOM_connection_last_event, that returns type
828 of last event (such as "receive data", "send data", "apdu received",
831 New ZOOM option, schema, that specifies schema for retrieval.
833 New CCL feature. Qualifiers can be aliases for one or more
834 other qualifiers (if more than one is given, OR is used).
836 ZOOM uses named result sets if target supports it.
838 Two new YAZ client commands: . (dot, which sources a script of YAZ
839 client commands), and ! (to execute shell command.). Implemented
842 Working on Debian packages.
846 YAZ client enables named result sets only if target supports it.
848 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
850 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
851 with key="host" to get same result.
853 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
854 Function Z3950_resultset_record(s) returns references to records
855 "owned" by resultset. To become owner use Z3950_record_clone.
857 Function z_ext_record handles Extended Services. Thanks to
862 CCL Parser fix: ignore token comma when dealing with and-lists.
864 Documentation updates for COMSTACK.
866 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
867 Changed prototype Z3950_records. For some functions, int parameters
868 were changed to size_t.
870 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
873 New MARC decode/display function, marc_display_exl, which properly rejects
874 non-ISO2709 records. YAZ client uses it.
878 Fix bug: local attribute set wasn't set correctly in PQF strings.
882 * Old Z39.50 codecs no longer supported.
884 Added ZOOM C binding. See http://zoom.z3950.org/
886 Renamed states for COMSTACKs to avoid confusion with events.
888 Implemented cs_look and proper cs_rcvconnect.
890 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
892 Configure detects POSIX threads on OpenBSD.
894 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
895 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
897 When error is returned from present handler, non-surrogate diagnostic
898 is returned in present response (and fetch handler is no longer called).
900 * Minor adjustments to pquery parser (PQF). Token characters may be
901 escaped by using backslash (C-style).
903 PQF parser allows string attribute values to be specified. For @attr,
904 non-numeric characters after the equal-sign are treated as strings
905 (e.g. @attr 9=title).
907 CCL trunction character may be defined (@truncation in file)
909 * function zget_ExtendedServicesRequest sets waitAction to
910 waitIfPossible (was wait).
912 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
915 CCL operator names may be set in field definition files (CCL_bibset).
916 See ccl/bib1 for an example.
918 Fixes in ASN.1 compiler for C++ compatibility.
920 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
921 and "op_or" to avoid conflict with C++.
923 Fixed problem with GNU readline detection on Redhat 7.0.
925 Added step-size for Scan backend handler.
927 Fixed bug that made the frontend server crash when no attribute
928 set was specified for scan.
930 Front-end server automatically switches to original working directory
931 when installed as an NT service. Previously -w had to be specified to
934 Added extended attributes for retrieval module (data1), so that data1
935 records carry d1_readXML/SGML attributes. d1_read also supports
936 null-data rules ( <tag/>)
938 On UNIX when POSIX threads are available, a separate library libyazthread
939 is created. Programmers should link with that library and the yaz library
940 when using threads. The reason for the split was that some applications
941 on Linux, such as Apache, doesn't work well when using shared objects that
944 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
945 (or any frontend server) in SSL mode by specifying ssl: followed by
946 address. Only tested on UNIX.
948 Added feature for CCL module. Virtual structure s=al or s=ol generates
949 and-list and or-list respectively instead of phrase search.
953 * Added prefix "yaz_" for the functions log_init.., log_file.. and
954 log_mask_str. This was done to avoid name conflicts with other libraries
955 (such as other PHP extensions).
957 Added raw OID member for preferred record syntax (request_format_raw)
958 and returned record syntax (output_format_raw) for backend fetch method.
960 Config file yaz-config now accepts options so that it returns specific
961 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
963 Shared library support for UNIX using GNU libtool.
965 * Modified backend interface. Request/Response struct's replaced by
966 one read/write C struct. For example bend_fetchrequest and
967 bend_fetchresult have been replaced by single bend_fetch_rr struct.
968 Every handler - even search has to be registered in bend_init
969 handler. This means that the YAZ library no longer refers to
970 external functions and it makes it possible to make the whole
971 thing a single DLL/SO.
973 Added Segment handler for backend server.
975 Added Zmbol/Zebra administrative functions to YAZ client.
977 Threaded frontend server on UNIX (when POSIX Threads are available).
978 Starting the server with option -T enables multi-threading.
982 Added configure option --enable-comp/disable-comp to control use
983 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
984 located in sub directory asn.
986 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
987 in ${exec_prefix}/bin along with the other programs yaz-client and
990 GNU automake used to maintain makefiles.
994 Changed retrieval module so that we can load records with no abstract
995 syntax defined. Tagpaths in these records are fully composed of string
998 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1002 On UNIX, the generated makefile now supports a proper 'make install'.
1003 The prefix can be set via GNU configure to set the install location
1004 (default is /usr/local).
1006 * YAZ programs client and ztest were renamed to yaz-client and
1007 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1008 locations, such as /usr/bin,/usr/local/bin,etc.
1010 * YAZ Header files were moved from include to include/yaz. YAZ Header
1011 files are referred to as include <yaz/log.h> rather than <log.h>.
1012 The YAZ include path (-I ..) is therefore the same as before. Programmers
1013 should update their #include statements or use -Ipath/include/yaz
1014 instead. The main motivation for doing this change is that YAZ header files
1015 can be installed in "standard" locations /usr/include,/usr/local/include
1016 without introducing conflicts, since ALL YAZ header files are stored
1017 in subdirectory yaz (under /usr/include for example).
1019 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1020 rather than project/workspace files. We switched because project files
1021 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1024 Changed name of logging function, logf, to yaz_log, to prevent name
1025 clash with some math-log functions. The YAZ header log.h defines logf
1026 to yaz_log (#define) so there should be no incompatibilities by this
1029 Added bend_start/bend_stop handlers for server. These handler are
1030 called on start/stop of server. For windows they are called whenever
1031 a service is started/stopped.
1033 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1034 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1035 in util/yc.tcl. The auto-generated C code structures are, in a few
1036 cases, incompatible with the old decoders. There are differences in the
1037 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1038 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1039 The preprocessor variable ASN_COMPILED is defined when the compiled
1040 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1041 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1042 wish to use the old encoders/decoders you can specify --disable-yc
1045 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1046 version so that it supports both new - and old version of DB Update
1048 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1049 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1050 change. The name parameter can be set to 0 in which no name is specified
1051 for the construction. The macros odr_implicit and odr_explicit sets name
1052 parameter to zero for the construction involved. New macros
1053 odr_implicit_tag and odr_explicit_tag are similar to the others,
1054 except that a name parameter is added. For programmers' that don't use
1055 ODR they probably only need to change the call to z_APDU and z_External.
1057 Added access control facility by interfacing the TCP wrapper library.
1058 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1059 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1060 name of the daemon and enables the access control as specified in
1061 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1063 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1064 den Dool <H.M.vdnDool@kub.nl>.
1066 Added reference ID parameter to most functions in server API - refer
1067 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1069 Changed name of ccl library to libccl.a (was ccl.a).
1071 Fixed bug in decoder for Explain (Category TargetInfo).
1073 Added support for GNU readline in client. Thanks to Jacob Poulsen
1074 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1076 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1077 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1078 IMPLEMENTATION! This change was made to the development version before
1079 the ZIG decided to retract the amendment. If any users MUST be
1080 compatible with the original Update definition, PLEASE CONTACT US, and
1081 we will include a separate definition corresponding to the old Update
1082 ES. Note that because of the change to the ASN.1 of the
1083 TaskPackageRecordStructure we cannot define a single structure that
1084 will support both versions.
1086 * Added const modifier to buffer parameter for some ODR/BER encoding
1087 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1088 completeWAIS, odr_dumpBER.
1090 Fixed bug in client.c which caused a crash when a scanResponse didn't
1091 contain positionOfTerm.
1093 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1094 * will cause an error in a client if a non-YAZ target sends both a
1095 * list of Scan entries and non-surrogate diagnostics.
1097 Retrieval module enhancements. Tag sets may be typed in the reference
1098 to it. From the .abs-file the "tagset" directive takes a third optional
1099 integer type for the tag set referenced. From a .tag-file the "include"
1100 directive takes a third optional type as well. The old "type" directive
1101 in the tag set itself is still recognized but acts as the default type
1104 Backend interface change. Individual Scan terms returned from bend_scan
1105 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1106 in include/backend.h.
1108 Retrieval module enhancements. Multiple tag sets and attribute sets may
1109 be specified in abstract syntax specs. Revised the error/warning for
1110 logging messages reported by the retrieval module when reading the
1113 Object Identifier system (oid_..) changed. The API is backwards
1114 compatible but the oid-routines now allocates new OID's when needed.
1115 Raw OID's may be specified in oid_getvalbyname.
1117 YAZ now uses GNU configure to generate Makefile(s).
1119 * Minor changes in some of the member names of DeleteResultSetRequest and
1120 DeleteResultSetResponse. See include/proto.h.
1122 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1123 and added member 'languages' in TargetInfo (which was missing).
1125 Changed the way attribute sets are handled in the retrieval
1126 module. These are now cached, just like the abstract syntaxes
1129 Changed YAZ so that it links with compiled ASN.1.
1131 Added Explain-schema definitions and mapping routines. The following
1132 Explain categories have been implemented: AttributeDetails,
1133 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1135 Fixed minor bug in Windows version of Server Library.
1137 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1139 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1141 Added EXTERNAL: UNIverse Resource Report (non-standard).
1143 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1144 ENUMERATED and SET OF.
1146 * Added 'const' to some of the char pointer arguments for the
1147 functions, data1_read_node, data1_getelementbytagname,
1148 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1151 Fixed bug in data1_insert_taggeddata - the last_child member of
1152 parent wasn't initialised.
1154 * Changed data1_read_record and data1_read_node so that the supplied
1155 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1156 doesn't refer to any parts of the "SGML"-buffer.
1158 Fixed bug in server library (Windows version of statserv_remove).
1160 * Changed code so that it compiles as C++. The type definition
1161 of Odr_fun which is a member of Odr_arm was changed. The result is,
1162 that an explicit typecast is needed for the fun pointer when
1163 using Odr_arm - as in:
1164 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1166 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1168 Implemented the new structured date and time definition as approved
1169 by the ZIG. Added schemaId element to the specificTag in Espec-1
1170 (also approved at the last ZIG). Thanks to RVDM.
1172 Added some Object identifiers (RVDM).
1174 Changed the Update Extended Service (RVDM).
1176 Added command "refid" to client which specifies referenceId for
1177 the following requests.
1179 Implemented extended service handling for server. See ztest.c
1180 for an example as well as backend.h. New handlers are registerd
1181 in the Init handler.
1183 * Changed interface for sort in server.
1185 Added new members to statserv_options_block. It allows a server
1186 to read options from another source than just the command line. Thanks
1187 to Charles Woodfield.
1189 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1190 renamed to zboolean. Some C++ compilers complained about the name.
1192 Minor changes to gils.abs. Added index 's' (sort) on title
1193 and date/time-last-modified.
1195 --- 1.4pl2 1998/1/30
1197 Fixed bug in server library regarding inetd mode (-i). This bug
1198 was introduced by release 1.4.
1200 --- 1.4pl1 1998/1/29
1202 Added sort facility in client and backend server interface.
1204 Fixed problem with dependencies in Makefile(s).
1206 Fixed bugs for encoders/decoders of extended services and
1209 Implemented sub-tree feature for schemas. Sub-trees are
1210 referenced in *.abs-files. See explain.abs for an example
1211 of the use of this feature.
1213 Modified bib1.att; local attributes for ANY didn't include
1214 ANY itself (only affects use of the retrieval module).
1216 Fixed bug in plain SGML reader in function data1_read_node:
1217 tags with prefix "var" was incorrectly interpreted as variants.
1219 Added feature "sub-schemas" to enable references to - and definitions
1220 of - group of elements.
1222 * Removed member parent from type data1_element (in data1.h).
1224 Implemented function odr_nullval() that returns the value of
1227 * Removed member num_children from data1_node (in data1.h).
1229 Made NT service interface part of the server library. The
1230 function statserv_main uses the NT service when required and
1231 calls the statserv_start / statserv_close routines.
1233 Routine zget_SearchRequest and zget_PresentRequest fills
1234 resultSetName/Id member with "default" instead of "Default".
1236 Fixed memory leak in server. Request queue member wasn't freed.
1238 Fixed nmem_exit so that memory is freed.
1242 Revised the CCL parser utility to be thread safe.
1244 Added function, oid_ent_to_oid, to replace the function
1245 oid_getoidbyent, which is not thread safe.
1247 * Added nmem_init and nmem_exit to initialize and release
1248 NMEM resources. Function nmem_init should be called once in the
1249 initial thread before NMEM/ODR is used. statserv.c and client.c
1250 have been changed accordingly. The change was necessary to make
1251 NMEM thread safe. The NMEM memory pool is shared amongst threads
1252 in a process. Unix-based applications will still work fine without
1255 Added NT Services interface for the the Z39.50 (statserv) Server.
1256 Refer to the ztest.c source on the usage.
1258 Windows 95/NT port using MSVC5.0. Project files are included in the
1261 * Defined new 'global' handle for the retrieval (data1) system. The
1262 new handled, data1_handle, describes the state of the data1 system.
1263 This handle is passed as first argument to virtually all
1264 data1 related routines. The functions data1_create and data1_destroy
1265 creates and destroys a data1 handle respectively.
1267 Added ODR encode stream member to all backend request structures
1268 init, search, scan etc. This stream should be used to allocate all
1269 memory used for the response when thread safe operation is needed.
1271 Changed the comstack utility, cs_addstr, to be thread safe. The
1272 returned hostname string returned by the function is now part the
1275 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1276 function. The cs_straddr takes a COMSTACK handle as argument, so this
1277 function must be used after cs_create and before bind/connect.
1278 This function is thread safe.
1280 Moved test server to 'ztest' directory - generic server code still
1281 in 'server' directory.
1283 Made prefix query (pquery.c) utility thread safe.
1285 Added new function modifier YAZ_EXPORT to 'export' public DLL
1286 functions when using windows (see include/yconfig.h).
1288 Added definitions to the OID database (util/oid.c) (RVDM).
1290 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1292 Added call to ccl_rpn_delete in client program.
1294 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1295 release of RPN structure.
1297 Added support for C++, headers uses extern "C" for public definitions.
1298 With input from RVDM.
1300 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1301 Thanks to Ronald van der Meer (RVDM).
1303 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1305 Added support for private extensions to the OID database
1306 (oid_setprivateoids()). Thanks to RVDM.
1308 Added optional, physical ANY (key replication)
1310 Fixed null-reference problem in GRS-1 output filter.
1312 Proximity operator added to Prefix Query Format (PQF).
1314 In test client command "base" accepts multiple databases.
1316 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1320 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1322 Smallish bug-fixes in the new encoders/decoders (explain).

1332 Added Update extended service.
1334 Added SearchResult-1 additional info structure.
1336 Added optional CCL (ISO8777) interpreter as separate module. Available
1339 --- 1.2 1996/6/10 (1st anniversary release)
1341 Added Summary record syntax. Lightly tested.
1343 Added OPAC record syntax. Untested.
1345 Added ResourceReport service encoders/decoders. Untested.
1347 Fixed bug in z_Unit - wrong tagging on unitSystem.

1353 Added documentation of query-language parsers and other supporting utilities.
1355 [frontend-server] Added Attribute set to the bend_scanrequest API.
1357 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1358 surrogate diagnostics were generated.
1360 [retrieval] Allow multiple local values for attribute.
1362 [retrieval] Allow multiple attributes per element in .abs files. index type.
1364 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1366 --- 1.1pl2 1996/4/10
1368 Minor changes, mostly specific to Zebra's requirements (retrieval)
1372 Repaired bug in frontend server when running multiple listening
1373 endpoints in dynamic mode.
1375 z_External() now won't break if a known, ASN.1 value comes encapsulated
1376 in an octet-string. The value will pass through unmodified in an Odr_oct.
1378 Added a bit of code to the demo client to decode & display
1379 ASN.1-structured records represented in the octet-aligned branch of
1380 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1382 Added z_ext_getentbyref() to the ASN module. Doc updated.
1384 * Completed the SCAN definition in the ASN module. This may break SCAN
1385 code based on older YAZ-versions at compile-time. The fix is easy -
1388 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1389 under the SCAN definition. Remember to initialize this, server-people.
1391 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1392 that this does not extend to ODR and ASN.
1394 Comstack allows insertion of established socket (primarily for
1395 inetd-operation of servers). Doc updated.
1397 Front-end server can now start from the inetd in TCP mode. Doc
1400 --- 1.0pl4 1996/1/24
1404 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1405 the rank and record number.
1407 Adjustments to the frontend server.
1409 Fixed diagnostic BER dumper. It ignored the file argument.
1413 Various changes to retrieval module.
1415 Changed the union discriminators of the protocol files from enums to
1416 ints paired with #defines.
1418 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1421 *Changed operator in the RPN structure to 'roperator', again to avoid a
1424 Fixed problems in Explain decoders/encoders.
1426 --- 1.0pl2 1995/12/6
1428 Memory bug in log module fixed.
1430 --- 1.0pl1 1995/12/5
1432 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1434 Bug in Explain DatabaseInfo module fixed.
1436 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1440 The shift to v1.0 signals that we now consider the *core* functionality
1441 of YAZ reasonably stable (the core being more or less equivalent to
1442 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1443 tested (Explain not at all - though that will happen soonish).
1445 Minor changes to code to support Windows port.
1447 Various minor changes after we're getting to use GRS-1 & co. more.
1449 Added Espec-1 format.
1451 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1452 of the protocol and it cannot be selected when encoding (maps into 'string'
1453 when decoding). Needed to talk to some servers.
1455 Demo client can request simple element set names.
1457 Added Diagnostic Format encoders/decoders.
1459 Added simple Close handling to frontend server (no hooks for resource
1460 reporting yet), and demonstration client.
1462 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1464 --- 1.0b3 1995/08/24
1466 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1467 handled incorrectly when records were requested in the searchResponse. This
1468 will only affect you if you use the frontend-server.
1470 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1471 Test-client will ask for and print GRS1. Ztest will return dummy records
1474 Added Explain encoders/decoders to the service-level API. Untested.
1476 Added Extended Services: Item Order encoders and decoders to the Service-
1477 level API. Untested. We could use a recent copy of the pertinent bits
1478 of the ILL protocol to add those bits.
1480 Added diagnostic format 1 encoders/decoders to the service-level API.
1483 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1484 odr_cons.c, which causes a more correct output.
1486 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1487 was always set to 0 when no records were requested in the searchRequest.
1489 * Added better external-handling. This shouldn't harm old code that
1490 *encodes* externals. It can break code that looks for a
1491 'single-ASN1-type' representation, since those types that are known
1492 are now decoded immediately. Look at the SUTRS sample code in
1493 seshigh.c and client.c. Documentation updated.
1495 Handling of structured records in bend_fetchresponse. Length -1 marks
1496 structured record, type is deduced from format field.
1498 --- 1.0b2 1995/06/27
1499 Fairly quick maintenance release to add SUTRS support.
1501 Fixed handling of SUTRS records in the demonstration client.
1503 * Added format field to the bend_fetchrequest and bend_fetchresponce
1504 structures of the backend API (frontend server). When the record is
1505 returned, the value of the format field is mapped to an OID. The
1506 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1507 of the record. The special value VAL_NONE in the bend_request means
1508 that no specific format was requested by the client. Documentation
1509 updated accordingly. Test server (ztest) will return a fixed dummy
1510 SUTRS record if your client requests SUTRS.
1512 Documentation updated accordingly.
1514 You can now set external libraries and RANLIB support in the top-level
1518 First public release.
