1 Possible compatibility problems with earlier versions marked with '*'.
5 Added support for virtual hosts and multiple backend servers for
6 the YAZ frontend server. The configution is XML based and
7 support specificition of CQL to RPN mappings and explain information.
8 See section "Virtual Hosts" in the YAZ manual.
10 Extended OPAC display utility. OPAC display utility renders
11 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
12 to supplement yaz_marc_decode_wrbuf.
16 Fixes for UNIX domain sockets. Bug #261.
18 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
20 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
21 Added yaz_marc_subfield_str which defines subfield lead string which is
22 used in YAZ_MARC_LINE format. Default string is blank+$. Added
23 yaz_marc_endline_str which defines end of fields string used in
24 YAZ_MARC_LINE format. Default string is newline.
26 Experimental support for MarcXChange. This format can be produced
27 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
28 http://www.bs.dk/standards/MarcXchange.xsd
30 Added yaz-client commands scansize that sets maximum number of
31 entries to be returned by scan.
35 Added support for SRW scan in yaz-client and Generic Frontend Server.
37 * Added whereInList member to SRW Scan Term.
39 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
41 Fixed NMEM system to return aligned blocks on the smallest boundaries
42 that are suitably aligned for all possible types on the particular
43 architecture YAZ is being built for.
47 Fixed numerious warnings that was issued with newer versions of GCC.
49 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
50 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
53 Make YAZ Generic Frontend Server slightly faster.
55 Enhance (and reduce) logging for Generic Frontend Server.
57 Revert YAZ log system so that it flushes every write operation
58 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
60 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
61 instead of LOG_, due to name clash with syslog(3). LOG_ are still
62 present. New applications should define YAZ_USE_NEW_LOG=1 - this
63 will effectively disable old definitions.
67 Added yaz_log_time_format which specifies log format using
70 Added yaz_log_module_level which returns mask for a module. Value
71 is non-zero mask a if module is enabled; zero if disabled.
73 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
76 Fixed bug #176: Dont throw diagnostics on empty SRU args.
78 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
80 Fixed bug #172: RPM builds does not enable SSL.
82 Doxyfile.in part of dist. Doxyfile generated by configure.
84 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
85 are given and the corresponding component does not exist.
87 Extend CCL documentation in YAZ reference. Describe r=r.
91 Fixed MARC->MARCXML conversion to properly deal with
92 fields, subfields, indicators having non-ASCII characters.
94 Fixed MARC->MARCXML conversion so that ASCII control characters
95 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
98 Added YAZ GFS support for conversion from Z39.50 surrogate
99 diagnostics to SRW surrogate diagnostics.
101 Bug fix: YAZ GFS did not return schema in explainResponse.
103 --- 2.0.25 2004/09/30
105 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
106 now converts recordSchema to elementSetName as well as schema URI.
108 Fixed bug in COMSTACK that prevented HTTP request packages from being
111 --- 2.0.24 2004/09/29
113 Added CCL facility r=r "range" which is similar to r=o "ordered" but
114 does not require white-space before and after the dash in a range, e.g.
115 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
118 Fixed a few AC_TRY_LINK configure tests that did not operate properly
119 due to new GCC removing "redundant" code.
121 Added yaz-client commands scanpos and scanstep that sets preferred
122 position and step-size for scan.
124 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
126 Added CCL utility ccl_qual_buf which parses one or more CCL
127 spec lines in a buffer.
129 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
130 of name and value - ignoring empty lines and comments.
132 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
134 Added odr_get_element_path which returns current element path for an
135 ODR handle. This utility is useful in error handling or user-defined
138 Added ODR_PRINT utility odr_set_stream which is is a more generic
139 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
140 to a write function and pointer to close function. The close function - if
141 non-NULL - will be called during odr_destroy.
143 Fixed bug in CCL parser where truncation char was not removed from
144 right side when truncation=both was in effect.
146 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
149 --- 2.0.23 2004/08/11
151 Fix buffer overrun in CQL parser when dealing with proximity (%).
153 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
154 to UTF-8/UCS conversion is now only based on codetables.xml.
156 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
158 --- 2.0.22 2004/08/06
160 Add support for more "commit changes" in ZOOM (uses Extended Services).
162 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
165 Yet another small fix for configure of SSL.
167 --- 2.0.21 2004/05/14
169 Fix SSL libs for configure when --with-openssl=DIR is given.
171 --- 2.0.20 2004/05/10
173 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
175 SSL comstack now uses yaz.pem certificate file on server side
176 by default. Certificate filename can be configured by calling
177 comstack function cs_set_ssl_certificate_file before cs_bind is used.
179 Fix bug regarding multiple calls to ZOOM_connection_connect.
181 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
183 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
184 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
186 ZOOM now allows inspection of X509 peer certificate for verification.
187 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
189 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
190 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
191 as "modular" but it simplifies things.
193 Added cs_get_peer_certificate to that returns peer X509 PEM.
195 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
196 NULL if SSL is unavailable.
198 Documentation about MARC decoding tools.
200 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
202 --- 2.0.19 2004/03/30
204 Rename CHANGELOG to NEWS to follow GNU style packing.
206 Fix bug with missing initialization of member in init_diagnostics.
207 This bug affects threaded version of GFS server.
209 --- 2.0.18 2004/03/20
211 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
214 Ensure zlib.dll is packed with Windows install.
216 --- 2.0.17 2004/03/17
218 Fix encoding of xsd:string to use text instead of CDATA.
220 Fix endless loop in CQL parser with unbalanced ".
222 Use a more compact way to store MARC-8 conversion tables.
224 --- 2.0.16 2004/03/16 Debian only
226 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
229 Update CQL parser to use new CQL 1.1 modifiers for booleans and
234 --- 2.0.15 2004/03/01
236 Another fix for decoding of XML packed records.
238 --- 2.0.14 2004/02/25
240 Fixes for Chunked encoding. White space not ignored after length spec.
242 Update NS and use default NS for SRW diagnostic elements.
244 --- 2.0.13 2004/02/23
246 Implement ZOOM_resultset_cache_reset which resets record cache.
248 Implement ZOOM_resultset_sort which sorts a result set.
250 Implement chunked HTTP transfer.
252 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
254 --- 2.0.12 2004/02/16
256 Added member 'schema' to bend_explain_rr structure so that backend
257 can specify explain record identifier. Defaults to Zeerex 2.0.
259 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
261 --- 2.0.11 2004/02/16
263 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
266 Added init command for yaz-client which sends "extra" init request.
268 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
269 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
271 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
273 Make ZOOM error code for "invalid query".
275 Fixed compilation for SSL which wasn't properly enabled for all platforms.
277 --- 2.0.10 2004/02/05
279 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
282 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
284 Added option -p <file> to make Generic Frontend Server to write PID file.
286 Added option -D to put Generic Frontend Server in background on its own.
288 Make ZOOM C recognize option "password". If unset, "pass" is used
289 (for backwards compatibility).
291 Fixed a bug in Generic Frontend Server that could make it crash if a
292 client sets characterSetNegotation bit, but didn't pass negotiation stuff
295 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
296 Must be issued before open, in order to be in effect.
298 --- 2.0.9-6 2004/01/12 Debian/Windows
300 Make the SRU server more picky WRT unknown params, etc.
302 Bug fix: ZOOM scan response didn't return displayTerm - when present.
304 New YAZ client command, options, that sets Z39.50 options.
306 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
307 options from a string of tokens (one token for each option bit).
309 Update SRW diagnostic code messages.
311 --- 2.0.9-5 2004/01/07 Debian/Windows
313 Handle user defined stylesheet for SRW/SRU.
315 --- 2.0.9-4 2004/01/06 Debian/Windows
317 Fix bug in decoding of Content-Length.
319 --- 2.0.9-3 2004/01/06 Debian/Windows
321 Fix a bug with decoding of XML packed records.
323 --- 2.0.9-2 2004/01/05 Debian only
325 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
327 Fix bug in SRW/SRU diagnostics decoding.
331 Fixed bug in Generic Frontend Server which could drop records exceeding
332 preferred message size. Reported and fixed by Irina Dijour.
334 Fixed calculation of package size for structured records in Generic
335 Frontend Server. Reported and fixed by Irina Dijour.
337 Fixed namespace for SRW/SRU diagnostics.
339 Fixed SEGV in yaz-client that occured for HTTP connection errors.
343 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
344 this version is incompatible with version 1.0 and older YAZ SRW/SRU
347 CQL changes to reflect recent changes to the specification:
348 * Documentation talks about context sets instead of index sets.
349 * Documentation talks about indexes instead of qualifiers.
350 * The CQL-to-PQF transformer's configuration file now uses
351 "index.set.name = <attributes>" instead of the old form
352 "qualifier.set.name = <attributes>". (Both forms are still
353 understood but the latter is deprecated.)
354 * CQL terms with no explicit index specified are now interpreted as
355 cql.serverChoice instead of srw.serverChoice (which of course
356 behaves exactly the same.)
360 MARC conversion can now generate ISO2709 output in another
361 character set. yaz-marcdump uses this facility if you invoke it
364 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
365 functions from there can be used from C++.
369 Frontend server now transfers memory from decoded packages to stream
372 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
373 references to show up.
375 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
376 the ZOOM Abstract API. The older names for the same options are still
377 also supported for the benefit of old applications.
379 ZOOM-C supports "implementationId" and "implementationVersion" options
380 to go along with "implementationName". These allow the user code to
381 specify identification strings to be sent to servers.
382 Add OID for the new ExtLite attribute set.
384 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
385 as requested/supplid by Ere Maijala <ere@atp.fi>
387 For generic frontend server, reverse the order of
388 "toolkit-supplied / application-supplied" strings sent as implementationId,
389 Name and Version. Also, remove the spaces around the slash. This brings
390 the GFS in line with the behaviour of ZOOM-C on the client side.
392 Add function ZOOM_scanset_display_term.
394 yaz-client shows scan displayTerm if present.
396 Utility yaz-iconv is now installed by default along with the man page
399 Extend configure check for OpenSSL to use pkg-config where available (such
402 Incorporate patch by Morten Bogeskov which allows a Unix file socket
403 server to specify uid/gid/mask for socket using the format
404 unix:[user=uid,][group=gid,][umask=mask,]file=path
405 If file= is omitted the existing format is assumed, e.g.
407 in which case the mask is 0666 (rw for everybody).
409 Major restructure of YAZ source. All source in libyaz is in src directory.
410 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
411 util (utility programs such as ASN.1 compiler, yaz-marcdump).
413 Added man page for utility yaz-marcdump (used to be called marcdump).
414 yaz-marcdump is installed by 'make install'.
416 Fixed a memory leak in Generic Frontend Server that occurred when decoding
417 of incoming package failed.
419 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
421 Change prototype of odr_perror: add const to message string.
423 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
425 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
426 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
427 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
428 DNS lookup. There should not be any compatibility problems with this
429 assuming that blocking=1 or 0 is used.
431 Fix bad reference in UNIX comstack in function cs_addrstr.
433 Fix for compilation on AIX.
435 The generic front-end server (server/seshigh.c) now supports returning
436 Init diagnostics to the client in User-information-field, in
437 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
442 Allow any CQL relation (not just all,any,exact,scr).
444 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
445 that features the same UI.
447 Implemented command update0 in YAZ client which is equivalent to
448 update but uses old of Ext Update ASN.1.
450 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
451 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
452 Previously no OID was used for this info.
454 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
455 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
456 returns 'malformed search term' otherwise.
458 SortResponse member resultCount now set to NULL in sort handler of
461 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
464 Add three new utility functions for translating OIDs between various
465 formats -- symbolic name such as "Usmarc", minus-1-terminated int
466 arrays and dotted strings such as "1.2.840.10003.9.5.1":
467 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
468 char *oid_to_dotstring(const int *oid, char *oidbuf);
469 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
471 Reverted modifications for ES Update definition for z_IU0Update
472 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
473 is back to YAZ 2.0.2.
475 String value attributes for CCL parser.
477 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
478 which their FirstSearch server returns in Init responses, sometimes
479 carrying useful diagnostic information when Init fails. This has the
480 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
481 "z39.50/oclcui.asn", where its definition is somewhat different from
482 what OCLC document on their web-site, as required to interoperate with
485 Support for anonymous authentication in yaz-client. Use the command
488 * Fix the OID of the Index Data-local "admin" Extended Service from
489 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
490 the 1000, which indicates a locally-defined OID, was a mistake.
494 Fix CCL directive @case handling so that it affects string match for
495 both CCL keywords and qualifiers.
497 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
498 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
499 Decoder has been updated with ASN.1 changes as listed in
500 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
501 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
502 z_IUUpdate, remains unchanged.
504 ZOOM_record_get may now return a record in a specific character set.
505 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
506 "from" is the character set of record as returned by target. "to" is
507 the character set to be returned. If omitted, "to" is UTF-8.
509 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
511 New ODR utility, odr_getelement, which returns name of element for
512 which encoding/decoding failed.
514 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
515 in cases where a required element was omitted.
517 Bug fix: some MARC8 sequences were not converted.
519 New ZOOM option "step" which specifies number of records to be
520 retrieved in one chunk. Used in conjunction with "start" and "count".
522 SRW support for yaz-client. Use scheme http: to use it, e.g.
525 yaz-client no longer does (un)intelligent character set conversions
526 by default. Can be enabled with charset and marc_charset commands.
528 xmalloc trace fix for 64-bit systems such as DEC alpha.
530 Solaris 2.6 compile fix.
532 New function, cql_strerror() translates SRW error codes, as returned
533 by cql_transform_error(), into human-readable English strings. Used
534 in yaz-client diagnostics when appropriate.
536 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
537 converts it into a type-1 query which is sent to the server. This
538 makes CQL available for use with all Z-servers, as opposed to the tiny
539 minority that can handle CQL queries themselves.
543 New Debian package layout similar to the Redhat Package layout.
545 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
546 and search result respectively.
550 Redhat package is now several packages: libyaz (runtime libraries),
551 libyaz-devel (development and documentation, and yaz (utility programs).
552 Package spec file by Morten Bøgeskov.
554 New member 'schema' in struct bend_fetch_rr which the name of requested
555 schema (SRW/SRU) for record (or NULL if none was given). The fetch
556 handler MAY set this to reflect the schema of the returned record.
558 New member 'display_term' in struct scan_entry. GFS now sets member entries
559 and allocates scan entries to be filled by user scan handler. In previous
560 version, entries member was allocated by the scan handler. That still works,
561 but the GFS will ignore member display_term - assuming it was NOT set by
562 the handler. The fact that the GFS now allocates the entries both allows
563 for new members and makes a scan handler easier to write.
565 Fix CQL lex buffer overflow.
567 SRW/SRU recordPacking. For SRW default recordPacking is string. For
568 SRU default recordPacking is string.
570 SRU protocol support for frontend server.
572 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
574 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
576 Added scan for the ZOOM shell (zoomsh).
580 * String Identifers for Schemas (Amendment 5).
581 http://lcweb.loc.gov/z3950/agency/amend/am5.html
582 Old definition for schema
583 Odr_oid *schema; /* OPT */
588 Z_InternationalString *uri;
589 #define Z_Schema_oid 1
590 #define Z_Schema_uri 2
593 * resultCount parameter to Sort Response (Amendment 1).
594 http://lcweb.loc.gov/z3950/agency/amend/am1.html
596 Support for SRW 1.0 over HTTP. This is an optional feature and
597 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
600 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
601 on the same port. SRW SearchRetrieveRequests are mapped
602 to bend_init,bend_search,bend_fetch,bend_close.
604 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
606 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
607 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
609 ZOOM connections are SRW based if schem http is used for hostname
610 in connect, e.g. z = ZOOM_connection_new("http://myserver");
611 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
613 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
614 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
615 distance=n, order=true/false, relation=le, prox unit=word. If
616 n is omitted, distance 1 is used.
618 Fixed problem with C compiler include path in wrong order.
620 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
621 on Solaris. Patch from Ko van der Sloot.
623 New MARC decode API. All new functions operate on a yaz_marc_t
624 handle. The most important new functions are: yaz_marc_create,
625 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
626 decode and destroy respectively. Decoder can produce formats
627 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
628 include/yaz/marcdisp.h.
630 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
631 to UTF-8, UCS-32, wchar_t or Latin-1.
633 * Prototypes for yaz_iconv_-functions moved to separate header
634 include/yaz/yaz-iconv.h.
636 Make a few private functions 'static' in unix.c. This prevents
637 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
639 For ZOOM connection, the options targetImplementation{Id,Name,Version}
640 are set when Init Response is received.
642 New function ZOOM_connection_error_x similar to ZOOM_connection_error
643 but returns diagnostic set as well.
645 New function yaz_strerror which is a portable wrapper for
646 strerror/strerror_r/GetLastMessage.
648 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
649 is returned for MARC. If type is "oai", then OAI MARC is returned.
651 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
656 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
658 Fix bad race conditions on SIGTERM and terminate gracefully in
661 Move retrieval (data1) module to Zebra since nobody seems to be
664 Add GRS-1 render for ZOOM using same format as yaz-client.
668 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
670 Fix broken ESpec handling in data1 module.
672 SGML reader parses comments and makes them part of the data1 tree.
674 Added several type casts so that YAZ compiles as C++ code.
676 ZOOM didn't handle PDU encoding failures properly.
678 Added more Bib-1 diagnostics (approved extensions).
680 GNU configure: better check for iconv.
682 More portable use of accept, getpeername. Check for socklen_t. Use
683 int/size_t if socklen_t is not defined.
687 PQF parser rejects bad queries - including those with extra
688 characters in them. PQF parser used to silently ignore that.
689 Cleaner API for PQF added, which allows you to get detailed
690 error information for bad queries (see yaz/pquery.h).
692 Fixed bug in ZOOM_record_get for type "database".
694 Implemented mini iconv library supporting conversions between
695 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
697 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
701 Fixed ZOOM C record cache so that preferredRecordSyntax and
702 elementSetName is used to check for already fetched records.
706 Added three members in bend_initrequest structure to facilitate
707 character set negotiation.
709 Fixed a bug in frontend server that could cause indefinite
710 loops under rare conditions.
712 Revised character set utilities (charneg.h) so that encoding
713 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
715 For PQF, directive @term <type> sets term type for Scan/Search.
716 Here <type> is general, string, numeric, null. The term type
717 is inherited - just like @attr.
719 New call odr_set_charset that sets character set conversion for
720 international-strings on a ODR stream. Prototype is:
721 int odr_set_charset(ODR o, const char *to, const char *from);
722 The InternationalString is still represented as C string in YAZ
723 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
724 won't). On the protocol level, you can use any encoding.
726 Support for UNIX sockets in ZOOM.
728 Solaris recv sometimes returns errno == ENOENT. It is treated as
729 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
731 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
732 both client and server. Code by Morten Bøgeskov.
736 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
737 that they can be used directly from Visual Basic. You must recompile
738 your windows APP if you're using ZOOM.
740 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
741 Commands "lang" and "charset" sets language and character set respectively.
742 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
743 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
745 Attributes from multiple CCL fields may be OR'ed rather than merged
746 using directive "@field or". Fields are still merged by default -
747 equivalent to "@field merge".
749 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
752 Fixed bug in zget for parameter ExtendedServicesResponse.
758 Added PQF feature: '@attr type=value' may be written as '@type=value'.
760 Client displays USR.1:SearchResult-1 (hits per term).
762 Additional Search Info for search in Generic Frontend Server.
764 Fixed CCL parsing of "field=s".
766 WIN32 installer - using the excellent NSIS software from nullsoft.
768 Fixed CCL parsing of "field = - <number>".
770 Added function yaz_marc_decode that decodes MARC for line mode
771 display or XML (similar to that used by JZKit).
773 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
774 Z39.50. But ISO/ILL was, however.
776 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
777 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
779 http://lcweb.loc.gov/z3950/agency/amend/am2.html
780 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
784 New YAZ client features: Command completion and new commands:
785 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
786 Code provided by Jacob Poulsen.
788 New call oid_trav, that visits all registered OIDs via callback.
790 Function ZOOM_record_get now returns const char pointer rather than
791 void pointer. It saves a lot of type casts.
793 For YAZ client, command "auth" now allows you to set authentication
794 in IdPass style. It is enabled when three tokens are given - order
795 is user, group and password.
797 Fix memory leaks in MARC record handling for ZOOM.
799 New option for YAZ client, -k <kilobytes> that sets
800 maximum record size. Similar to -k option for generic frontend
801 server and yaz-ztest.
803 More fixes for scan. Non-zero stepSize handled. OID's fixes.
805 Prefix query parser reports "fail" when bad attribute set is given.
807 Fix in MARC decoder. Proximity logging. Fix for attribute set
808 in scan handler for server. Patches by Shigeru Ishida.
810 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
813 Configure option --with-openssl=<dir> now works when a directory is
814 specified. Patch provided by Morten Bøgeskov.
816 New option for YAZ client, -u <auth>, that sets authentication.
818 ZOOM fix: error information was sometimes "missing", since error
819 was cleared/reset too when it shouldn't.
821 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
825 Scan for ZOOM API. New object ZOOM_scanset. New functions
826 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
827 ZOOM_scanset_destroy.
829 New ZOOM function, ZOOM_connection_last_event, that returns type
830 of last event (such as "receive data", "send data", "apdu received",
833 New ZOOM option, schema, that specifies schema for retrieval.
835 New CCL feature. Qualifiers can be aliases for one or more
836 other qualifiers (if more than one is given, OR is used).
838 ZOOM uses named result sets if target supports it.
840 Two new YAZ client commands: . (dot, which sources a script of YAZ
841 client commands), and ! (to execute shell command.). Implemented
844 Working on Debian packages.
848 YAZ client enables named result sets only if target supports it.
850 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
852 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
853 with key="host" to get same result.
855 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
856 Function Z3950_resultset_record(s) returns references to records
857 "owned" by resultset. To become owner use Z3950_record_clone.
859 Function z_ext_record handles Extended Services. Thanks to
864 CCL Parser fix: ignore token comma when dealing with and-lists.
866 Documentation updates for COMSTACK.
868 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
869 Changed prototype Z3950_records. For some functions, int parameters
870 were changed to size_t.
872 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
875 New MARC decode/display function, marc_display_exl, which properly rejects
876 non-ISO2709 records. YAZ client uses it.
880 Fix bug: local attribute set wasn't set correctly in PQF strings.
884 * Old Z39.50 codecs no longer supported.
886 Added ZOOM C binding. See http://zoom.z3950.org/
888 Renamed states for COMSTACKs to avoid confusion with events.
890 Implemented cs_look and proper cs_rcvconnect.
892 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
894 Configure detects POSIX threads on OpenBSD.
896 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
897 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
899 When error is returned from present handler, non-surrogate diagnostic
900 is returned in present response (and fetch handler is no longer called).
902 * Minor adjustments to pquery parser (PQF). Token characters may be
903 escaped by using backslash (C-style).
905 PQF parser allows string attribute values to be specified. For @attr,
906 non-numeric characters after the equal-sign are treated as strings
907 (e.g. @attr 9=title).
909 CCL trunction character may be defined (@truncation in file)
911 * function zget_ExtendedServicesRequest sets waitAction to
912 waitIfPossible (was wait).
914 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
917 CCL operator names may be set in field definition files (CCL_bibset).
918 See ccl/bib1 for an example.
920 Fixes in ASN.1 compiler for C++ compatibility.
922 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
923 and "op_or" to avoid conflict with C++.
925 Fixed problem with GNU readline detection on Redhat 7.0.
927 Added step-size for Scan backend handler.
929 Fixed bug that made the frontend server crash when no attribute
930 set was specified for scan.
932 Front-end server automatically switches to original working directory
933 when installed as an NT service. Previously -w had to be specified to
936 Added extended attributes for retrieval module (data1), so that data1
937 records carry d1_readXML/SGML attributes. d1_read also supports
938 null-data rules ( <tag/>)
940 On UNIX when POSIX threads are available, a separate library libyazthread
941 is created. Programmers should link with that library and the yaz library
942 when using threads. The reason for the split was that some applications
943 on Linux, such as Apache, doesn't work well when using shared objects that
946 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
947 (or any frontend server) in SSL mode by specifying ssl: followed by
948 address. Only tested on UNIX.
950 Added feature for CCL module. Virtual structure s=al or s=ol generates
951 and-list and or-list respectively instead of phrase search.
955 * Added prefix "yaz_" for the functions log_init.., log_file.. and
956 log_mask_str. This was done to avoid name conflicts with other libraries
957 (such as other PHP extensions).
959 Added raw OID member for preferred record syntax (request_format_raw)
960 and returned record syntax (output_format_raw) for backend fetch method.
962 Config file yaz-config now accepts options so that it returns specific
963 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
965 Shared library support for UNIX using GNU libtool.
967 * Modified backend interface. Request/Response struct's replaced by
968 one read/write C struct. For example bend_fetchrequest and
969 bend_fetchresult have been replaced by single bend_fetch_rr struct.
970 Every handler - even search has to be registered in bend_init
971 handler. This means that the YAZ library no longer refers to
972 external functions and it makes it possible to make the whole
973 thing a single DLL/SO.
975 Added Segment handler for backend server.
977 Added Zmbol/Zebra administrative functions to YAZ client.
979 Threaded frontend server on UNIX (when POSIX Threads are available).
980 Starting the server with option -T enables multi-threading.
984 Added configure option --enable-comp/disable-comp to control use
985 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
986 located in sub directory asn.
988 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
989 in ${exec_prefix}/bin along with the other programs yaz-client and
992 GNU automake used to maintain makefiles.
996 Changed retrieval module so that we can load records with no abstract
997 syntax defined. Tagpaths in these records are fully composed of string
1000 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1004 On UNIX, the generated makefile now supports a proper 'make install'.
1005 The prefix can be set via GNU configure to set the install location
1006 (default is /usr/local).
1008 * YAZ programs client and ztest were renamed to yaz-client and
1009 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1010 locations, such as /usr/bin,/usr/local/bin,etc.
1012 * YAZ Header files were moved from include to include/yaz. YAZ Header
1013 files are referred to as include <yaz/log.h> rather than <log.h>.
1014 The YAZ include path (-I ..) is therefore the same as before. Programmers
1015 should update their #include statements or use -Ipath/include/yaz
1016 instead. The main motivation for doing this change is that YAZ header files
1017 can be installed in "standard" locations /usr/include,/usr/local/include
1018 without introducing conflicts, since ALL YAZ header files are stored
1019 in subdirectory yaz (under /usr/include for example).
1021 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1022 rather than project/workspace files. We switched because project files
1023 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1026 Changed name of logging function, logf, to yaz_log, to prevent name
1027 clash with some math-log functions. The YAZ header log.h defines logf
1028 to yaz_log (#define) so there should be no incompatibilities by this
1031 Added bend_start/bend_stop handlers for server. These handler are
1032 called on start/stop of server. For windows they are called whenever
1033 a service is started/stopped.
1035 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1036 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1037 in util/yc.tcl. The auto-generated C code structures are, in a few
1038 cases, incompatible with the old decoders. There are differences in the
1039 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1040 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1041 The preprocessor variable ASN_COMPILED is defined when the compiled
1042 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1043 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1044 wish to use the old encoders/decoders you can specify --disable-yc
1047 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1048 version so that it supports both new - and old version of DB Update
1050 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1051 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1052 change. The name parameter can be set to 0 in which no name is specified
1053 for the construction. The macros odr_implicit and odr_explicit sets name
1054 parameter to zero for the construction involved. New macros
1055 odr_implicit_tag and odr_explicit_tag are similar to the others,
1056 except that a name parameter is added. For programmers' that don't use
1057 ODR they probably only need to change the call to z_APDU and z_External.
1059 Added access control facility by interfacing the TCP wrapper library.
1060 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1061 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1062 name of the daemon and enables the access control as specified in
1063 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1065 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1066 den Dool <H.M.vdnDool@kub.nl>.
1068 Added reference ID parameter to most functions in server API - refer
1069 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1071 Changed name of ccl library to libccl.a (was ccl.a).
1073 Fixed bug in decoder for Explain (Category TargetInfo).
1075 Added support for GNU readline in client. Thanks to Jacob Poulsen
1076 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1078 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1079 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1080 IMPLEMENTATION! This change was made to the development version before
1081 the ZIG decided to retract the amendment. If any users MUST be
1082 compatible with the original Update definition, PLEASE CONTACT US, and
1083 we will include a separate definition corresponding to the old Update
1084 ES. Note that because of the change to the ASN.1 of the
1085 TaskPackageRecordStructure we cannot define a single structure that
1086 will support both versions.
1088 * Added const modifier to buffer parameter for some ODR/BER encoding
1089 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1090 completeWAIS, odr_dumpBER.
1092 Fixed bug in client.c which caused a crash when a scanResponse didn't
1093 contain positionOfTerm.
1095 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1096 * will cause an error in a client if a non-YAZ target sends both a
1097 * list of Scan entries and non-surrogate diagnostics.
1099 Retrieval module enhancements. Tag sets may be typed in the reference
1100 to it. From the .abs-file the "tagset" directive takes a third optional
1101 integer type for the tag set referenced. From a .tag-file the "include"
1102 directive takes a third optional type as well. The old "type" directive
1103 in the tag set itself is still recognized but acts as the default type
1106 Backend interface change. Individual Scan terms returned from bend_scan
1107 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1108 in include/backend.h.
1110 Retrieval module enhancements. Multiple tag sets and attribute sets may
1111 be specified in abstract syntax specs. Revised the error/warning for
1112 logging messages reported by the retrieval module when reading the
1115 Object Identifier system (oid_..) changed. The API is backwards
1116 compatible but the oid-routines now allocates new OID's when needed.
1117 Raw OID's may be specified in oid_getvalbyname.
1119 YAZ now uses GNU configure to generate Makefile(s).
1121 * Minor changes in some of the member names of DeleteResultSetRequest and
1122 DeleteResultSetResponse. See include/proto.h.
1124 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1125 and added member 'languages' in TargetInfo (which was missing).
1127 Changed the way attribute sets are handled in the retrieval
1128 module. These are now cached, just like the abstract syntaxes
1131 Changed YAZ so that it links with compiled ASN.1.
1133 Added Explain-schema definitions and mapping routines. The following
1134 Explain categories have been implemented: AttributeDetails,
1135 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1137 Fixed minor bug in Windows version of Server Library.
1139 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1141 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1143 Added EXTERNAL: UNIverse Resource Report (non-standard).
1145 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1146 ENUMERATED and SET OF.
1148 * Added 'const' to some of the char pointer arguments for the
1149 functions, data1_read_node, data1_getelementbytagname,
1150 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1153 Fixed bug in data1_insert_taggeddata - the last_child member of
1154 parent wasn't initialised.
1156 * Changed data1_read_record and data1_read_node so that the supplied
1157 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1158 doesn't refer to any parts of the "SGML"-buffer.
1160 Fixed bug in server library (Windows version of statserv_remove).
1162 * Changed code so that it compiles as C++. The type definition
1163 of Odr_fun which is a member of Odr_arm was changed. The result is,
1164 that an explicit typecast is needed for the fun pointer when
1165 using Odr_arm - as in:
1166 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1168 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1170 Implemented the new structured date and time definition as approved
1171 by the ZIG. Added schemaId element to the specificTag in Espec-1
1172 (also approved at the last ZIG). Thanks to RVDM.
1174 Added some Object identifiers (RVDM).
1176 Changed the Update Extended Service (RVDM).
1178 Added command "refid" to client which specifies referenceId for
1179 the following requests.
1181 Implemented extended service handling for server. See ztest.c
1182 for an example as well as backend.h. New handlers are registerd
1183 in the Init handler.
1185 * Changed interface for sort in server.
1187 Added new members to statserv_options_block. It allows a server
1188 to read options from another source than just the command line. Thanks
1189 to Charles Woodfield.
1191 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1192 renamed to zboolean. Some C++ compilers complained about the name.
1194 Minor changes to gils.abs. Added index 's' (sort) on title
1195 and date/time-last-modified.
1197 --- 1.4pl2 1998/1/30
1199 Fixed bug in server library regarding inetd mode (-i). This bug
1200 was introduced by release 1.4.
1202 --- 1.4pl1 1998/1/29
1204 Added sort facility in client and backend server interface.
1206 Fixed problem with dependencies in Makefile(s).
1208 Fixed bugs for encoders/decoders of extended services and
1211 Implemented sub-tree feature for schemas. Sub-trees are
1212 referenced in *.abs-files. See explain.abs for an example
1213 of the use of this feature.
1215 Modified bib1.att; local attributes for ANY didn't include
1216 ANY itself (only affects use of the retrieval module).
1218 Fixed bug in plain SGML reader in function data1_read_node:
1219 tags with prefix "var" was incorrectly interpreted as variants.
1221 Added feature "sub-schemas" to enable references to - and definitions
1222 of - group of elements.
1224 * Removed member parent from type data1_element (in data1.h).
1226 Implemented function odr_nullval() that returns the value of
1229 * Removed member num_children from data1_node (in data1.h).
1231 Made NT service interface part of the server library. The
1232 function statserv_main uses the NT service when required and
1233 calls the statserv_start / statserv_close routines.
1235 Routine zget_SearchRequest and zget_PresentRequest fills
1236 resultSetName/Id member with "default" instead of "Default".
1238 Fixed memory leak in server. Request queue member wasn't freed.
1240 Fixed nmem_exit so that memory is freed.
1244 Revised the CCL parser utility to be thread safe.
1246 Added function, oid_ent_to_oid, to replace the function
1247 oid_getoidbyent, which is not thread safe.
1249 * Added nmem_init and nmem_exit to initialize and release
1250 NMEM resources. Function nmem_init should be called once in the
1251 initial thread before NMEM/ODR is used. statserv.c and client.c
1252 have been changed accordingly. The change was necessary to make
1253 NMEM thread safe. The NMEM memory pool is shared amongst threads
1254 in a process. Unix-based applications will still work fine without
1257 Added NT Services interface for the the Z39.50 (statserv) Server.
1258 Refer to the ztest.c source on the usage.
1260 Windows 95/NT port using MSVC5.0. Project files are included in the
1263 * Defined new 'global' handle for the retrieval (data1) system. The
1264 new handled, data1_handle, describes the state of the data1 system.
1265 This handle is passed as first argument to virtually all
1266 data1 related routines. The functions data1_create and data1_destroy
1267 creates and destroys a data1 handle respectively.
1269 Added ODR encode stream member to all backend request structures
1270 init, search, scan etc. This stream should be used to allocate all
1271 memory used for the response when thread safe operation is needed.
1273 Changed the comstack utility, cs_addstr, to be thread safe. The
1274 returned hostname string returned by the function is now part the
1277 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1278 function. The cs_straddr takes a COMSTACK handle as argument, so this
1279 function must be used after cs_create and before bind/connect.
1280 This function is thread safe.
1282 Moved test server to 'ztest' directory - generic server code still
1283 in 'server' directory.
1285 Made prefix query (pquery.c) utility thread safe.
1287 Added new function modifier YAZ_EXPORT to 'export' public DLL
1288 functions when using windows (see include/yconfig.h).
1290 Added definitions to the OID database (util/oid.c) (RVDM).
1292 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1294 Added call to ccl_rpn_delete in client program.
1296 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1297 release of RPN structure.
1299 Added support for C++, headers uses extern "C" for public definitions.
1300 With input from RVDM.
1302 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1303 Thanks to Ronald van der Meer (RVDM).
1305 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1307 Added support for private extensions to the OID database
1308 (oid_setprivateoids()). Thanks to RVDM.
1310 Added optional, physical ANY (key replication)
1312 Fixed null-reference problem in GRS-1 output filter.
1314 Proximity operator added to Prefix Query Format (PQF).
1316 In test client command "base" accepts multiple databases.
1318 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1322 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1324 Smallish bug-fixes in the new encoders/decoders (explain).

1334 Added Update extended service.
1336 Added SearchResult-1 additional info structure.
1338 Added optional CCL (ISO8777) interpreter as separate module. Available
1341 --- 1.2 1996/6/10 (1st anniversary release)
1343 Added Summary record syntax. Lightly tested.
1345 Added OPAC record syntax. Untested.
1347 Added ResourceReport service encoders/decoders. Untested.
1349 Fixed bug in z_Unit - wrong tagging on unitSystem.

1355 Added documentation of query-language parsers and other supporting utilities.
1357 [frontend-server] Added Attribute set to the bend_scanrequest API.
1359 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1360 surrogate diagnostics were generated.
1362 [retrieval] Allow multiple local values for attribute.
1364 [retrieval] Allow multiple attributes per element in .abs files. index type.
1366 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1368 --- 1.1pl2 1996/4/10
1370 Minor changes, mostly specific to Zebra's requirements (retrieval)
1374 Repaired bug in frontend server when running multiple listening
1375 endpoints in dynamic mode.
1377 z_External() now won't break if a known, ASN.1 value comes encapsulated
1378 in an octet-string. The value will pass through unmodified in an Odr_oct.
1380 Added a bit of code to the demo client to decode & display
1381 ASN.1-structured records represented in the octet-aligned branch of
1382 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1384 Added z_ext_getentbyref() to the ASN module. Doc updated.
1386 * Completed the SCAN definition in the ASN module. This may break SCAN
1387 code based on older YAZ-versions at compile-time. The fix is easy -
1390 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1391 under the SCAN definition. Remember to initialize this, server-people.
1393 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1394 that this does not extend to ODR and ASN.
1396 Comstack allows insertion of established socket (primarily for
1397 inetd-operation of servers). Doc updated.
1399 Front-end server can now start from the inetd in TCP mode. Doc
1402 --- 1.0pl4 1996/1/24
1406 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1407 the rank and record number.
1409 Adjustments to the frontend server.
1411 Fixed diagnostic BER dumper. It ignored the file argument.
1415 Various changes to retrieval module.
1417 Changed the union discriminators of the protocol files from enums to
1418 ints paired with #defines.
1420 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1423 *Changed operator in the RPN structure to 'roperator', again to avoid a
1426 Fixed problems in Explain decoders/encoders.
1428 --- 1.0pl2 1995/12/6
1430 Memory bug in log module fixed.
1432 --- 1.0pl1 1995/12/5
1434 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1436 Bug in Explain DatabaseInfo module fixed.
1438 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1442 The shift to v1.0 signals that we now consider the *core* functionality
1443 of YAZ reasonably stable (the core being more or less equivalent to
1444 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1445 tested (Explain not at all - though that will happen soonish).
1447 Minor changes to code to support Windows port.
1449 Various minor changes after we're getting to use GRS-1 & co. more.
1451 Added Espec-1 format.
1453 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1454 of the protocol and it cannot be selected when encoding (maps into 'string'
1455 when decoding). Needed to talk to some servers.
1457 Demo client can request simple element set names.
1459 Added Diagnostic Format encoders/decoders.
1461 Added simple Close handling to frontend server (no hooks for resource
1462 reporting yet), and demonstration client.
1464 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1466 --- 1.0b3 1995/08/24
1468 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1469 handled incorrectly when records were requested in the searchResponse. This
1470 will only affect you if you use the frontend-server.
1472 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1473 Test-client will ask for and print GRS1. Ztest will return dummy records
1476 Added Explain encoders/decoders to the service-level API. Untested.
1478 Added Extended Services: Item Order encoders and decoders to the Service-
1479 level API. Untested. We could use a recent copy of the pertinent bits
1480 of the ILL protocol to add those bits.
1482 Added diagnostic format 1 encoders/decoders to the service-level API.
1485 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1486 odr_cons.c, which causes a more correct output.
1488 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1489 was always set to 0 when no records were requested in the searchRequest.
1491 * Added better external-handling. This shouldn't harm old code that
1492 *encodes* externals. It can break code that looks for a
1493 'single-ASN1-type' representation, since those types that are known
1494 are now decoded immediately. Look at the SUTRS sample code in
1495 seshigh.c and client.c. Documentation updated.
1497 Handling of structured records in bend_fetchresponse. Length -1 marks
1498 structured record, type is deduced from format field.
1500 --- 1.0b2 1995/06/27
1501 Fairly quick maintenance release to add SUTRS support.
1503 Fixed handling of SUTRS records in the demonstration client.
1505 * Added format field to the bend_fetchrequest and bend_fetchresponce
1506 structures of the backend API (frontend server). When the record is
1507 returned, the value of the format field is mapped to an OID. The
1508 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1509 of the record. The special value VAL_NONE in the bend_request means
1510 that no specific format was requested by the client. Documentation
1511 updated accordingly. Test server (ztest) will return a fixed dummy
1512 SUTRS record if your client requests SUTRS.
1514 Documentation updated accordingly.
1516 You can now set external libraries and RANLIB support in the top-level
1520 First public release.
