1 Possible compatibility problems with earlier versions marked with '*'.
5 Fix SSL libs for configure when --with-openssl=DIR is given.
9 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
11 SSL comstack now uses yaz.pem certificate file on server side
12 by default. Certificate filename can be configured by calling
13 comstack function cs_set_ssl_certificate_file before cs_bind is used.
15 Fix bug regarding multiple calls to ZOOM_connection_connect.
17 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
19 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
20 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
22 ZOOM now allows inspection of X509 peer certificate for verification.
23 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
25 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
26 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
27 as "modular" but it simplifies things.
29 Added cs_get_peer_certificate to that returns peer X509 PEM.
31 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
32 NULL if SSL is unavailable.
34 Documentation about MARC decoding tools.
36 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
40 Rename CHANGELOG to NEWS to follow GNU style packing.
42 Fix bug with missing initialization of member in init_diagnostics.
43 This bug affects threaded version of GFS server.
47 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
50 Ensure zlib.dll is packed with Windows install.
54 Fix encoding of xsd:string to use text instead of CDATA.
56 Fix endless loop in CQL parser with unbalanced ".
58 Use a more compact way to store MARC-8 conversion tables.
60 --- 2.0.16 2004/03/16 Debian only
62 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
65 Update CQL parser to use new CQL 1.1 modifiers for booleans and
72 Another fix for decoding of XML packed records.
76 Fixes for Chunked encoding. White space not ignored after length spec.
78 Update NS and use default NS for SRW diagnostic elements.
82 Implement ZOOM_resultset_cache_reset which resets record cache.
84 Implement ZOOM_resultset_sort which sorts a result set.
86 Implement chunked HTTP transfer.
88 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
92 Added member 'schema' to bend_explain_rr structure so that backend
93 can specify explain record identifier. Defaults to Zeerex 2.0.
95 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
99 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
102 Added init command for yaz-client which sends "extra" init request.
104 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
105 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
107 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
109 Make ZOOM error code for "invalid query".
111 Fixed compilation for SSL which wasn't properly enabled for all platforms.
113 --- 2.0.10 2004/02/05
115 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
118 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
120 Added option -p <file> to make Generic Frontend Server to write PID file.
122 Added option -D to put Generic Frontend Server in background on its own.
124 Make ZOOM C recognize option "password". If unset, "pass" is used
125 (for backwards compatibility).
127 Fixed a bug in Generic Frontend Server that could make it crash if a
128 client sets characterSetNegotation bit, but didn't pass negotiation stuff
131 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
132 Must be issued before open, in order to be in effect.
134 --- 2.0.9-6 2004/01/12 Debian/Windows
136 Make the SRU server more picky WRT unknown params, etc.
138 Bug fix: ZOOM scan response didn't return displayTerm - when present.
140 New YAZ client command, options, that sets Z39.50 options.
142 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
143 options from a string of tokens (one token for each option bit).
145 Update SRW diagnostic code messages.
147 --- 2.0.9-5 2004/01/07 Debian/Windows
149 Handle user defined stylesheet for SRW/SRU.
151 --- 2.0.9-4 2004/01/06 Debian/Windows
153 Fix bug in decoding of Content-Length.
155 --- 2.0.9-3 2004/01/06 Debian/Windows
157 Fix a bug with decoding of XML packed records.
159 --- 2.0.9-2 2004/01/05 Debian only
161 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
163 Fix bug in SRW/SRU diagnostics decoding.
167 Fixed bug in Generic Frontend Server which could drop records exceeding
168 preferred message size. Reported and fixed by Irina Dijour.
170 Fixed calculation of package size for structured records in Generic
171 Frontend Server. Reported and fixed by Irina Dijour.
173 Fixed namespace for SRW/SRU diagnostics.
175 Fixed SEGV in yaz-client that occured for HTTP connection errors.
179 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
180 this version is incompatible with version 1.0 and older YAZ SRW/SRU
183 CQL changes to reflect recent changes to the specification:
184 * Documentation talks about context sets instead of index sets.
185 * Documentation talks about indexes instead of qualifiers.
186 * The CQL-to-PQF transformer's configuration file now uses
187 "index.set.name = <attributes>" instead of the old form
188 "qualifier.set.name = <attributes>". (Both forms are still
189 understood but the latter is deprecated.)
190 * CQL terms with no explicit index specified are now interpreted as
191 cql.serverChoice instead of srw.serverChoice (which of course
192 behaves exactly the same.)
196 MARC conversion can now generate ISO2709 output in another
197 character set. yaz-marcdump uses this facility if you invoke it
200 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
201 functions from there can be used from C++.
205 Frontend server now transfers memory from decoded packages to stream
208 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
209 references to show up.
211 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
212 the ZOOM Abstract API. The older names for the same options are still
213 also supported for the benefit of old applications.
215 ZOOM-C supports "implementationId" and "implementationVersion" options
216 to go along with "implementationName". These allow the user code to
217 specify identification strings to be sent to servers.
218 Add OID for the new ExtLite attribute set.
220 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
221 as requested/supplid by Ere Maijala <ere@atp.fi>
223 For generic frontend server, reverse the order of
224 "toolkit-supplied / application-supplied" strings sent as implementationId,
225 Name and Version. Also, remove the spaces around the slash. This brings
226 the GFS in line with the behaviour of ZOOM-C on the client side.
228 Add function ZOOM_scanset_display_term.
230 yaz-client shows scan displayTerm if present.
232 Utility yaz-iconv is now installed by default along with the man page
235 Extend configure check for OpenSSL to use pkg-config where available (such
238 Incorporate patch by Morten Bogeskov which allows a Unix file socket
239 server to specify uid/gid/mask for socket using the format
240 unix:[user=uid,][group=gid,][umask=mask,]file=path
241 If file= is omitted the existing format is assumed, e.g.
243 in which case the mask is 0666 (rw for everybody).
245 Major restructure of YAZ source. All source in libyaz is in src directory.
246 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
247 util (utility programs such as ASN.1 compiler, yaz-marcdump).
249 Added man page for utility yaz-marcdump (used to be called marcdump).
250 yaz-marcdump is installed by 'make install'.
252 Fixed a memory leak in Generic Frontend Server that occurred when decoding
253 of incoming package failed.
255 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
257 Change prototype of odr_perror: add const to message string.
259 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
261 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
262 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
263 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
264 DNS lookup. There should not be any compatibility problems with this
265 assuming that blocking=1 or 0 is used.
267 Fix bad reference in UNIX comstack in function cs_addrstr.
269 Fix for compilation on AIX.
271 The generic front-end server (server/seshigh.c) now supports returning
272 Init diagnostics to the client in User-information-field, in
273 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
278 Allow any CQL relation (not just all,any,exact,scr).
280 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
281 that features the same UI.
283 Implemented command update0 in YAZ client which is equivalent to
284 update but uses old of Ext Update ASN.1.
286 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
287 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
288 Previously no OID was used for this info.
290 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
291 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
292 returns 'malformed search term' otherwise.
294 SortResponse member resultCount now set to NULL in sort handler of
297 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
300 Add three new utility functions for translating OIDs between various
301 formats -- symbolic name such as "Usmarc", minus-1-terminated int
302 arrays and dotted strings such as "1.2.840.10003.9.5.1":
303 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
304 char *oid_to_dotstring(const int *oid, char *oidbuf);
305 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
307 Reverted modifications for ES Update definition for z_IU0Update
308 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
309 is back to YAZ 2.0.2.
311 String value attributes for CCL parser.
313 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
314 which their FirstSearch server returns in Init responses, sometimes
315 carrying useful diagnostic information when Init fails. This has the
316 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
317 "z39.50/oclcui.asn", where its definition is somewhat different from
318 what OCLC document on their web-site, as required to interoperate with
321 Support for anonymous authentication in yaz-client. Use the command
324 * Fix the OID of the Index Data-local "admin" Extended Service from
325 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
326 the 1000, which indicates a locally-defined OID, was a mistake.
330 Fix CCL directive @case handling so that it affects string match for
331 both CCL keywords and qualifiers.
333 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
334 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
335 Decoder has been updated with ASN.1 changes as listed in
336 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
337 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
338 z_IUUpdate, remains unchanged.
340 ZOOM_record_get may now return a record in a specific character set.
341 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
342 "from" is the character set of record as returned by target. "to" is
343 the character set to be returned. If omitted, "to" is UTF-8.
345 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
347 New ODR utility, odr_getelement, which returns name of element for
348 which encoding/decoding failed.
350 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
351 in cases where a required element was omitted.
353 Bug fix: some MARC8 sequences were not converted.
355 New ZOOM option "step" which specifies number of records to be
356 retrieved in one chunk. Used in conjunction with "start" and "count".
358 SRW support for yaz-client. Use scheme http: to use it, e.g.
361 yaz-client no longer does (un)intelligent character set conversions
362 by default. Can be enabled with charset and marc_charset commands.
364 xmalloc trace fix for 64-bit systems such as DEC alpha.
366 Solaris 2.6 compile fix.
368 New function, cql_strerror() translates SRW error codes, as returned
369 by cql_transform_error(), into human-readable English strings. Used
370 in yaz-client diagnostics when appropriate.
372 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
373 converts it into a type-1 query which is sent to the server. This
374 makes CQL available for use with all Z-servers, as opposed to the tiny
375 minority that can handle CQL queries themselves.
379 New Debian package layout similar to the Redhat Package layout.
381 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
382 and search result respectively.
386 Redhat package is now several packages: libyaz (runtime libraries),
387 libyaz-devel (development and documentation, and yaz (utility programs).
388 Package spec file by Morten Bøgeskov.
390 New member 'schema' in struct bend_fetch_rr which the name of requested
391 schema (SRW/SRU) for record (or NULL if none was given). The fetch
392 handler MAY set this to reflect the schema of the returned record.
394 New member 'display_term' in struct scan_entry. GFS now sets member entries
395 and allocates scan entries to be filled by user scan handler. In previous
396 version, entries member was allocated by the scan handler. That still works,
397 but the GFS will ignore member display_term - assuming it was NOT set by
398 the handler. The fact that the GFS now allocates the entries both allows
399 for new members and makes a scan handler easier to write.
401 Fix CQL lex buffer overflow.
403 SRW/SRU recordPacking. For SRW default recordPacking is string. For
404 SRU default recordPacking is string.
406 SRU protocol support for frontend server.
408 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
410 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
412 Added scan for the ZOOM shell (zoomsh).
416 * String Identifers for Schemas (Amendment 5).
417 http://lcweb.loc.gov/z3950/agency/amend/am5.html
418 Old definition for schema
419 Odr_oid *schema; /* OPT */
424 Z_InternationalString *uri;
425 #define Z_Schema_oid 1
426 #define Z_Schema_uri 2
429 * resultCount parameter to Sort Response (Amendment 1).
430 http://lcweb.loc.gov/z3950/agency/amend/am1.html
432 Support for SRW 1.0 over HTTP. This is an optional feature and
433 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
436 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
437 on the same port. SRW SearchRetrieveRequests are mapped
438 to bend_init,bend_search,bend_fetch,bend_close.
440 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
442 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
443 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
445 ZOOM connections are SRW based if schem http is used for hostname
446 in connect, e.g. z = ZOOM_connection_new("http://myserver");
447 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
449 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
450 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
451 distance=n, order=true/false, relation=le, prox unit=word. If
452 n is omitted, distance 1 is used.
454 Fixed problem with C compiler include path in wrong order.
456 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
457 on Solaris. Patch from Ko van der Sloot.
459 New MARC decode API. All new functions operate on a yaz_marc_t
460 handle. The most important new functions are: yaz_marc_create,
461 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
462 decode and destroy respectively. Decoder can produce formats
463 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
464 include/yaz/marcdisp.h.
466 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
467 to UTF-8, UCS-32, wchar_t or Latin-1.
469 * Prototypes for yaz_iconv_-functions moved to separate header
470 include/yaz/yaz-iconv.h.
472 Make a few private functions 'static' in unix.c. This prevents
473 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
475 For ZOOM connection, the options targetImplementation{Id,Name,Version}
476 are set when Init Response is received.
478 New function ZOOM_connection_error_x similar to ZOOM_connection_error
479 but returns diagnostic set as well.
481 New function yaz_strerror which is a portable wrapper for
482 strerror/strerror_r/GetLastMessage.
484 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
485 is returned for MARC. If type is "oai", then OAI MARC is returned.
487 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
492 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
494 Fix bad race conditions on SIGTERM and terminate gracefully in
497 Move retrieval (data1) module to Zebra since nobody seems to be
500 Add GRS-1 render for ZOOM using same format as yaz-client.
504 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
506 Fix broken ESpec handling in data1 module.
508 SGML reader parses comments and makes them part of the data1 tree.
510 Added several type casts so that YAZ compiles as C++ code.
512 ZOOM didn't handle PDU encoding failures properly.
514 Added more Bib-1 diagnostics (approved extensions).
516 GNU configure: better check for iconv.
518 More portable use of accept, getpeername. Check for socklen_t. Use
519 int/size_t if socklen_t is not defined.
523 PQF parser rejects bad queries - including those with extra
524 characters in them. PQF parser used to silently ignore that.
525 Cleaner API for PQF added, which allows you to get detailed
526 error information for bad queries (see yaz/pquery.h).
528 Fixed bug in ZOOM_record_get for type "database".
530 Implemented mini iconv library supporting conversions between
531 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
533 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
537 Fixed ZOOM C record cache so that preferredRecordSyntax and
538 elementSetName is used to check for already fetched records.
542 Added three members in bend_initrequest structure to facilitate
543 character set negotiation.
545 Fixed a bug in frontend server that could cause indefinite
546 loops under rare conditions.
548 Revised character set utilities (charneg.h) so that encoding
549 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
551 For PQF, directive @term <type> sets term type for Scan/Search.
552 Here <type> is general, string, numeric, null. The term type
553 is inherited - just like @attr.
555 New call odr_set_charset that sets character set conversion for
556 international-strings on a ODR stream. Prototype is:
557 int odr_set_charset(ODR o, const char *to, const char *from);
558 The InternationalString is still represented as C string in YAZ
559 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
560 won't). On the protocol level, you can use any encoding.
562 Support for UNIX sockets in ZOOM.
564 Solaris recv sometimes returns errno == ENOENT. It is treated as
565 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
567 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
568 both client and server. Code by Morten Bøgeskov.
572 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
573 that they can be used directly from Visual Basic. You must recompile
574 your windows APP if you're using ZOOM.
576 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
577 Commands "lang" and "charset" sets language and character set respectively.
578 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
579 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
581 Attributes from multiple CCL fields may be OR'ed rather than merged
582 using directive "@field or". Fields are still merged by default -
583 equivalent to "@field merge".
585 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
588 Fixed bug in zget for parameter ExtendedServicesResponse.
594 Added PQF feature: '@attr type=value' may be written as '@type=value'.
596 Client displays USR.1:SearchResult-1 (hits per term).
598 Additional Search Info for search in Generic Frontend Server.
600 Fixed CCL parsing of "field=s".
602 WIN32 installer - using the excellent NSIS software from nullsoft.
604 Fixed CCL parsing of "field = - <number>".
606 Added function yaz_marc_decode that decodes MARC for line mode
607 display or XML (similar to that used by JZKit).
609 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
610 Z39.50. But ISO/ILL was, however.
612 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
613 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
615 http://lcweb.loc.gov/z3950/agency/amend/am2.html
616 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
620 New YAZ client features: Command completion and new commands:
621 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
622 Code provided by Jacob Poulsen.
624 New call oid_trav, that visits all registered OIDs via callback.
626 Function ZOOM_record_get now returns const char pointer rather than
627 void pointer. It saves a lot of type casts.
629 For YAZ client, command "auth" now allows you to set authentication
630 in IdPass style. It is enabled when three tokens are given - order
631 is user, group and password.
633 Fix memory leaks in MARC record handling for ZOOM.
635 New option for YAZ client, -k <kilobytes> that sets
636 maximum record size. Similar to -k option for generic frontend
637 server and yaz-ztest.
639 More fixes for scan. Non-zero stepSize handled. OID's fixes.
641 Prefix query parser reports "fail" when bad attribute set is given.
643 Fix in MARC decoder. Proximity logging. Fix for attribute set
644 in scan handler for server. Patches by Shigeru Ishida.
646 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
649 Configure option --with-openssl=<dir> now works when a directory is
650 specified. Patch provided by Morten Bøgeskov.
652 New option for YAZ client, -u <auth>, that sets authentication.
654 ZOOM fix: error information was sometimes "missing", since error
655 was cleared/reset too when it shouldn't.
657 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
661 Scan for ZOOM API. New object ZOOM_scanset. New functions
662 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
663 ZOOM_scanset_destroy.
665 New ZOOM function, ZOOM_connection_last_event, that returns type
666 of last event (such as "receive data", "send data", "apdu received",
669 New ZOOM option, schema, that specifies schema for retrieval.
671 New CCL feature. Qualifiers can be aliases for one or more
672 other qualifiers (if more than one is given, OR is used).
674 ZOOM uses named result sets if target supports it.
676 Two new YAZ client commands: . (dot, which sources a script of YAZ
677 client commands), and ! (to execute shell command.). Implemented
680 Working on Debian packages.
684 YAZ client enables named result sets only if target supports it.
686 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
688 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
689 with key="host" to get same result.
691 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
692 Function Z3950_resultset_record(s) returns references to records
693 "owned" by resultset. To become owner use Z3950_record_clone.
695 Function z_ext_record handles Extended Services. Thanks to
700 CCL Parser fix: ignore token comma when dealing with and-lists.
702 Documentation updates for COMSTACK.
704 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
705 Changed prototype Z3950_records. For some functions, int parameters
706 were changed to size_t.
708 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
711 New MARC decode/display function, marc_display_exl, which properly rejects
712 non-ISO2709 records. YAZ client uses it.
716 Fix bug: local attribute set wasn't set correctly in PQF strings.
720 * Old Z39.50 codecs no longer supported.
722 Added ZOOM C binding. See http://zoom.z3950.org/
724 Renamed states for COMSTACKs to avoid confusion with events.
726 Implemented cs_look and proper cs_rcvconnect.
728 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
730 Configure detects POSIX threads on OpenBSD.
732 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
733 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
735 When error is returned from present handler, non-surrogate diagnostic
736 is returned in present response (and fetch handler is no longer called).
738 * Minor adjustments to pquery parser (PQF). Token characters may be
739 escaped by using backslash (C-style).
741 PQF parser allows string attribute values to be specified. For @attr,
742 non-numeric characters after the equal-sign are treated as strings
743 (e.g. @attr 9=title).
745 CCL trunction character may be defined (@truncation in file)
747 * function zget_ExtendedServicesRequest sets waitAction to
748 waitIfPossible (was wait).
750 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
753 CCL operator names may be set in field definition files (CCL_bibset).
754 See ccl/bib1 for an example.
756 Fixes in ASN.1 compiler for C++ compatibility.
758 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
759 and "op_or" to avoid conflict with C++.
761 Fixed problem with GNU readline detection on Redhat 7.0.
763 Added step-size for Scan backend handler.
765 Fixed bug that made the frontend server crash when no attribute
766 set was specified for scan.
768 Front-end server automatically switches to original working directory
769 when installed as an NT service. Previously -w had to be specified to
772 Added extended attributes for retrieval module (data1), so that data1
773 records carry d1_readXML/SGML attributes. d1_read also supports
774 null-data rules ( <tag/>)
776 On UNIX when POSIX threads are available, a separate library libyazthread
777 is created. Programmers should link with that library and the yaz library
778 when using threads. The reason for the split was that some applications
779 on Linux, such as Apache, doesn't work well when using shared objects that
782 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
783 (or any frontend server) in SSL mode by specifying ssl: followed by
784 address. Only tested on UNIX.
786 Added feature for CCL module. Virtual structure s=al or s=ol generates
787 and-list and or-list respectively instead of phrase search.
791 * Added prefix "yaz_" for the functions log_init.., log_file.. and
792 log_mask_str. This was done to avoid name conflicts with other libraries
793 (such as other PHP extensions).
795 Added raw OID member for preferred record syntax (request_format_raw)
796 and returned record syntax (output_format_raw) for backend fetch method.
798 Config file yaz-config now accepts options so that it returns specific
799 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
801 Shared library support for UNIX using GNU libtool.
803 * Modified backend interface. Request/Response struct's replaced by
804 one read/write C struct. For example bend_fetchrequest and
805 bend_fetchresult have been replaced by single bend_fetch_rr struct.
806 Every handler - even search has to be registered in bend_init
807 handler. This means that the YAZ library no longer refers to
808 external functions and it makes it possible to make the whole
809 thing a single DLL/SO.
811 Added Segment handler for backend server.
813 Added Zmbol/Zebra administrative functions to YAZ client.
815 Threaded frontend server on UNIX (when POSIX Threads are available).
816 Starting the server with option -T enables multi-threading.
820 Added configure option --enable-comp/disable-comp to control use
821 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
822 located in sub directory asn.
824 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
825 in ${exec_prefix}/bin along with the other programs yaz-client and
828 GNU automake used to maintain makefiles.
832 Changed retrieval module so that we can load records with no abstract
833 syntax defined. Tagpaths in these records are fully composed of string
836 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
840 On UNIX, the generated makefile now supports a proper 'make install'.
841 The prefix can be set via GNU configure to set the install location
842 (default is /usr/local).
844 * YAZ programs client and ztest were renamed to yaz-client and
845 yaz-ztest to avoid conflicts when users install YAZ in "standard"
846 locations, such as /usr/bin,/usr/local/bin,etc.
848 * YAZ Header files were moved from include to include/yaz. YAZ Header
849 files are referred to as include <yaz/log.h> rather than <log.h>.
850 The YAZ include path (-I ..) is therefore the same as before. Programmers
851 should update their #include statements or use -Ipath/include/yaz
852 instead. The main motivation for doing this change is that YAZ header files
853 can be installed in "standard" locations /usr/include,/usr/local/include
854 without introducing conflicts, since ALL YAZ header files are stored
855 in subdirectory yaz (under /usr/include for example).
857 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
858 rather than project/workspace files. We switched because project files
859 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
862 Changed name of logging function, logf, to yaz_log, to prevent name
863 clash with some math-log functions. The YAZ header log.h defines logf
864 to yaz_log (#define) so there should be no incompatibilities by this
867 Added bend_start/bend_stop handlers for server. These handler are
868 called on start/stop of server. For windows they are called whenever
869 a service is started/stopped.
871 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
872 a fairly small ASN.1 compiler written in Tcl. The compiler is located
873 in util/yc.tcl. The auto-generated C code structures are, in a few
874 cases, incompatible with the old decoders. There are differences in the
875 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
876 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
877 The preprocessor variable ASN_COMPILED is defined when the compiled
878 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
879 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
880 wish to use the old encoders/decoders you can specify --disable-yc
883 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
884 version so that it supports both new - and old version of DB Update
886 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
887 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
888 change. The name parameter can be set to 0 in which no name is specified
889 for the construction. The macros odr_implicit and odr_explicit sets name
890 parameter to zero for the construction involved. New macros
891 odr_implicit_tag and odr_explicit_tag are similar to the others,
892 except that a name parameter is added. For programmers' that don't use
893 ODR they probably only need to change the call to z_APDU and z_External.
895 Added access control facility by interfacing the TCP wrapper library.
896 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
897 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
898 name of the daemon and enables the access control as specified in
899 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
901 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
902 den Dool <H.M.vdnDool@kub.nl>.
904 Added reference ID parameter to most functions in server API - refer
905 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
907 Changed name of ccl library to libccl.a (was ccl.a).
909 Fixed bug in decoder for Explain (Category TargetInfo).
911 Added support for GNU readline in client. Thanks to Jacob Poulsen
912 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
914 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
915 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
916 IMPLEMENTATION! This change was made to the development version before
917 the ZIG decided to retract the amendment. If any users MUST be
918 compatible with the original Update definition, PLEASE CONTACT US, and
919 we will include a separate definition corresponding to the old Update
920 ES. Note that because of the change to the ASN.1 of the
921 TaskPackageRecordStructure we cannot define a single structure that
922 will support both versions.
924 * Added const modifier to buffer parameter for some ODR/BER encoding
925 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
926 completeWAIS, odr_dumpBER.
928 Fixed bug in client.c which caused a crash when a scanResponse didn't
929 contain positionOfTerm.
931 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
932 * will cause an error in a client if a non-YAZ target sends both a
933 * list of Scan entries and non-surrogate diagnostics.
935 Retrieval module enhancements. Tag sets may be typed in the reference
936 to it. From the .abs-file the "tagset" directive takes a third optional
937 integer type for the tag set referenced. From a .tag-file the "include"
938 directive takes a third optional type as well. The old "type" directive
939 in the tag set itself is still recognized but acts as the default type
942 Backend interface change. Individual Scan terms returned from bend_scan
943 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
944 in include/backend.h.
946 Retrieval module enhancements. Multiple tag sets and attribute sets may
947 be specified in abstract syntax specs. Revised the error/warning for
948 logging messages reported by the retrieval module when reading the
951 Object Identifier system (oid_..) changed. The API is backwards
952 compatible but the oid-routines now allocates new OID's when needed.
953 Raw OID's may be specified in oid_getvalbyname.
955 YAZ now uses GNU configure to generate Makefile(s).
957 * Minor changes in some of the member names of DeleteResultSetRequest and
958 DeleteResultSetResponse. See include/proto.h.
960 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
961 and added member 'languages' in TargetInfo (which was missing).
963 Changed the way attribute sets are handled in the retrieval
964 module. These are now cached, just like the abstract syntaxes
967 Changed YAZ so that it links with compiled ASN.1.
969 Added Explain-schema definitions and mapping routines. The following
970 Explain categories have been implemented: AttributeDetails,
971 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
973 Fixed minor bug in Windows version of Server Library.
975 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
977 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
979 Added EXTERNAL: UNIverse Resource Report (non-standard).
981 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
982 ENUMERATED and SET OF.
984 * Added 'const' to some of the char pointer arguments for the
985 functions, data1_read_node, data1_getelementbytagname,
986 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
989 Fixed bug in data1_insert_taggeddata - the last_child member of
990 parent wasn't initialised.
992 * Changed data1_read_record and data1_read_node so that the supplied
993 "SGML"-buffer is read-only. In particular the resulting data1 - tree
994 doesn't refer to any parts of the "SGML"-buffer.
996 Fixed bug in server library (Windows version of statserv_remove).
998 * Changed code so that it compiles as C++. The type definition
999 of Odr_fun which is a member of Odr_arm was changed. The result is,
1000 that an explicit typecast is needed for the fun pointer when
1001 using Odr_arm - as in:
1002 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1004 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1006 Implemented the new structured date and time definition as approved
1007 by the ZIG. Added schemaId element to the specificTag in Espec-1
1008 (also approved at the last ZIG). Thanks to RVDM.
1010 Added some Object identifiers (RVDM).
1012 Changed the Update Extended Service (RVDM).
1014 Added command "refid" to client which specifies referenceId for
1015 the following requests.
1017 Implemented extended service handling for server. See ztest.c
1018 for an example as well as backend.h. New handlers are registerd
1019 in the Init handler.
1021 * Changed interface for sort in server.
1023 Added new members to statserv_options_block. It allows a server
1024 to read options from another source than just the command line. Thanks
1025 to Charles Woodfield.
1027 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1028 renamed to zboolean. Some C++ compilers complained about the name.
1030 Minor changes to gils.abs. Added index 's' (sort) on title
1031 and date/time-last-modified.
1033 --- 1.4pl2 1998/1/30
1035 Fixed bug in server library regarding inetd mode (-i). This bug
1036 was introduced by release 1.4.
1038 --- 1.4pl1 1998/1/29
1040 Added sort facility in client and backend server interface.
1042 Fixed problem with dependencies in Makefile(s).
1044 Fixed bugs for encoders/decoders of extended services and
1047 Implemented sub-tree feature for schemas. Sub-trees are
1048 referenced in *.abs-files. See explain.abs for an example
1049 of the use of this feature.
1051 Modified bib1.att; local attributes for ANY didn't include
1052 ANY itself (only affects use of the retrieval module).
1054 Fixed bug in plain SGML reader in function data1_read_node:
1055 tags with prefix "var" was incorrectly interpreted as variants.
1057 Added feature "sub-schemas" to enable references to - and definitions
1058 of - group of elements.
1060 * Removed member parent from type data1_element (in data1.h).
1062 Implemented function odr_nullval() that returns the value of
1065 * Removed member num_children from data1_node (in data1.h).
1067 Made NT service interface part of the server library. The
1068 function statserv_main uses the NT service when required and
1069 calls the statserv_start / statserv_close routines.
1071 Routine zget_SearchRequest and zget_PresentRequest fills
1072 resultSetName/Id member with "default" instead of "Default".
1074 Fixed memory leak in server. Request queue member wasn't freed.
1076 Fixed nmem_exit so that memory is freed.
1080 Revised the CCL parser utility to be thread safe.
1082 Added function, oid_ent_to_oid, to replace the function
1083 oid_getoidbyent, which is not thread safe.
1085 * Added nmem_init and nmem_exit to initialize and release
1086 NMEM resources. Function nmem_init should be called once in the
1087 initial thread before NMEM/ODR is used. statserv.c and client.c
1088 have been changed accordingly. The change was necessary to make
1089 NMEM thread safe. The NMEM memory pool is shared amongst threads
1090 in a process. Unix-based applications will still work fine without
1093 Added NT Services interface for the the Z39.50 (statserv) Server.
1094 Refer to the ztest.c source on the usage.
1096 Windows 95/NT port using MSVC5.0. Project files are included in the
1099 * Defined new 'global' handle for the retrieval (data1) system. The
1100 new handled, data1_handle, describes the state of the data1 system.
1101 This handle is passed as first argument to virtually all
1102 data1 related routines. The functions data1_create and data1_destroy
1103 creates and destroys a data1 handle respectively.
1105 Added ODR encode stream member to all backend request structures
1106 init, search, scan etc. This stream should be used to allocate all
1107 memory used for the response when thread safe operation is needed.
1109 Changed the comstack utility, cs_addstr, to be thread safe. The
1110 returned hostname string returned by the function is now part the
1113 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1114 function. The cs_straddr takes a COMSTACK handle as argument, so this
1115 function must be used after cs_create and before bind/connect.
1116 This function is thread safe.
1118 Moved test server to 'ztest' directory - generic server code still
1119 in 'server' directory.
1121 Made prefix query (pquery.c) utility thread safe.
1123 Added new function modifier YAZ_EXPORT to 'export' public DLL
1124 functions when using windows (see include/yconfig.h).
1126 Added definitions to the OID database (util/oid.c) (RVDM).
1128 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1130 Added call to ccl_rpn_delete in client program.
1132 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1133 release of RPN structure.
1135 Added support for C++, headers uses extern "C" for public definitions.
1136 With input from RVDM.
1138 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1139 Thanks to Ronald van der Meer (RVDM).
1141 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1143 Added support for private extensions to the OID database
1144 (oid_setprivateoids()). Thanks to RVDM.
1146 Added optional, physical ANY (key replication)
1148 Fixed null-reference problem in GRS-1 output filter.
1150 Proximity operator added to Prefix Query Format (PQF).
1152 In test client command "base" accepts multiple databases.
1154 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1158 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1160 Smallish bug-fixes in the new encoders/decoders (explain).
1162 Bug fixed in DeleteRequest.
1164 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1166 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1168 Added SOIF syntax (using private OID for now) to retrieval module and client.
1170 Added Update extended service.
1172 Added SearchResult-1 additional info structure.
1174 Added optional CCL (ISO8777) interpreter as separate module. Available
1177 --- 1.2 1996/6/10 (1st anniversary release)
1179 Added Summary record syntax. Lightly tested.
1181 Added OPAC record syntax. Untested.
1183 Added ResourceReport service encoders/decoders. Untested.
1185 Fixed bug in z_Unit - wrong tagging on unitSystem.
1187 Fixed bug in the DiagRecs decoder.
1189 Added options for max PDU size and session timeout to frontend-server.
1191 Added documentation of query-language parsers and other supporting utilities.
1193 [frontend-server] Added Attribute set to the bend_scanrequest API.
1195 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1196 surrogate diagnostics were generated.
1198 [retrieval] Allow multiple local values for attribute.
1200 [retrieval] Allow multiple attributes per element in .abs files. index type.
1202 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1204 --- 1.1pl2 1996/4/10
1206 Minor changes, mostly specific to Zebra's requirements (retrieval)
1210 Repaired bug in frontend server when running multiple listening
1211 endpoints in dynamic mode.
1213 z_External() now won't break if a known, ASN.1 value comes encapsulated
1214 in an octet-string. The value will pass through unmodified in an Odr_oct.
1216 Added a bit of code to the demo client to decode & display
1217 ASN.1-structured records represented in the octet-aligned branch of
1218 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1220 Added z_ext_getentbyref() to the ASN module. Doc updated.
1222 * Completed the SCAN definition in the ASN module. This may break SCAN
1223 code based on older YAZ-versions at compile-time. The fix is easy -
1226 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1227 under the SCAN definition. Remember to initialize this, server-people.
1229 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1230 that this does not extend to ODR and ASN.
1232 Comstack allows insertion of established socket (primarily for
1233 inetd-operation of servers). Doc updated.
1235 Front-end server can now start from the inetd in TCP mode. Doc
1238 --- 1.0pl4 1996/1/24
1242 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1243 the rank and record number.
1245 Adjustments to the frontend server.
1247 Fixed diagnostic BER dumper. It ignored the file argument.
1251 Various changes to retrieval module.
1253 Changed the union discriminators of the protocol files from enums to
1254 ints paired with #defines.
1256 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1259 *Changed operator in the RPN structure to 'roperator', again to avoid a
1262 Fixed problems in Explain decoders/encoders.
1264 --- 1.0pl2 1995/12/6
1266 Memory bug in log module fixed.
1268 --- 1.0pl1 1995/12/5
1270 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1272 Bug in Explain DatabaseInfo module fixed.
1274 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1278 The shift to v1.0 signals that we now consider the *core* functionality
1279 of YAZ reasonably stable (the core being more or less equivalent to
1280 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1281 tested (Explain not at all - though that will happen soonish).
1283 Minor changes to code to support Windows port.
1285 Various minor changes after we're getting to use GRS-1 & co. more.
1287 Added Espec-1 format.
1289 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1290 of the protocol and it cannot be selected when encoding (maps into 'string'
1291 when decoding). Needed to talk to some servers.
1293 Demo client can request simple element set names.
1295 Added Diagnostic Format encoders/decoders.
1297 Added simple Close handling to frontend server (no hooks for resource
1298 reporting yet), and demonstration client.
1300 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1302 --- 1.0b3 1995/08/24
1304 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1305 handled incorrectly when records were requested in the searchResponse. This
1306 will only affect you if you use the frontend-server.
1308 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1309 Test-client will ask for and print GRS1. Ztest will return dummy records
1312 Added Explain encoders/decoders to the service-level API. Untested.
1314 Added Extended Services: Item Order encoders and decoders to the Service-
1315 level API. Untested. We could use a recent copy of the pertinent bits
1316 of the ILL protocol to add those bits.
1318 Added diagnostic format 1 encoders/decoders to the service-level API.
1321 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1322 odr_cons.c, which causes a more correct output.
1324 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1325 was always set to 0 when no records were requested in the searchRequest.
1327 * Added better external-handling. This shouldn't harm old code that
1328 *encodes* externals. It can break code that looks for a
1329 'single-ASN1-type' representation, since those types that are known
1330 are now decoded immediately. Look at the SUTRS sample code in
1331 seshigh.c and client.c. Documentation updated.
1333 Handling of structured records in bend_fetchresponse. Length -1 marks
1334 structured record, type is deduced from format field.
1336 --- 1.0b2 1995/06/27
1337 Fairly quick maintenance release to add SUTRS support.
1339 Fixed handling of SUTRS records in the demonstration client.
1341 * Added format field to the bend_fetchrequest and bend_fetchresponce
1342 structures of the backend API (frontend server). When the record is
1343 returned, the value of the format field is mapped to an OID. The
1344 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
