37 Implement chunked HTTP transfer.
39 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
43 Added member 'schema' to bend_explain_rr structure so that backend
44 can specify explain record identifier. Defaults to Zeerex 2.0.
46 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
50 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
53 Added init command for yaz-client which sends "extra" init request.
55 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
56 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
58 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
60 Make ZOOM error code for "invalid query".
62 Fixed compilation for SSL which wasn't properly enabled for all platforms.
66 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
69 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
71 Added option -p <file> to make Generic Frontend Server to write PID file.
73 Added option -D to put Generic Frontend Server in background on its own.
75 Make ZOOM C recognize option "password". If unset, "pass" is used
76 (for backwards compatibility).
78 Fixed a bug in Generic Frontend Server that could make it crash if a
79 client sets characterSetNegotation bit, but didn't pass negotiation stuff
82 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
83 Must be issued before open, in order to be in effect.
85 --- 2.0.9-6 2004/01/12 Debian/Windows
87 Make the SRU server more picky WRT unknown params, etc.
89 Bug fix: ZOOM scan response didn't return displayTerm - when present.
91 New YAZ client command, options, that sets Z39.50 options.
93 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
94 options from a string of tokens (one token for each option bit).
96 Update SRW diagnostic code messages.
98 --- 2.0.9-5 2004/01/07 Debian/Windows

112 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
114 Fix bug in SRW/SRU diagnostics decoding.
118 Fixed bug in Generic Frontend Server which could drop records exceeding
119 preferred message size. Reported and fixed by Irina Dijour.
121 Fixed calculation of package size for structured records in Generic
122 Frontend Server. Reported and fixed by Irina Dijour.
124 Fixed namespace for SRW/SRU diagnostics.
126 Fixed SEGV in yaz-client that occured for HTTP connection errors.
130 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
131 this version is incompatible with version 1.0 and older YAZ SRW/SRU
134 CQL changes to reflect recent changes to the specification:
135 * Documentation talks about context sets instead of index sets.
136 * Documentation talks about indexes instead of qualifiers.
137 * The CQL-to-PQF transformer's configuration file now uses
138 "index.set.name = <attributes>" instead of the old form
139 "qualifier.set.name = <attributes>". (Both forms are still
140 understood but the latter is deprecated.)
141 * CQL terms with no explicit index specified are now interpreted as
142 cql.serverChoice instead of srw.serverChoice (which of course
143 behaves exactly the same.)
147 MARC conversion can now generate ISO2709 output in another
148 character set. yaz-marcdump uses this facility if you invoke it
151 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
152 functions from there can be used from C++.
156 Frontend server now transfers memory from decoded packages to stream
159 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
160 references to show up.
162 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
163 the ZOOM Abstract API. The older names for the same options are still
164 also supported for the benefit of old applications.
166 ZOOM-C supports "implementationId" and "implementationVersion" options
167 to go along with "implementationName". These allow the user code to
168 specify identification strings to be sent to servers.
169 Add OID for the new ExtLite attribute set.
171 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
172 as requested/supplid by Ere Maijala <ere@atp.fi>
174 For generic frontend server, reverse the order of
175 "toolkit-supplied / application-supplied" strings sent as implementationId,
176 Name and Version. Also, remove the spaces around the slash. This brings
177 the GFS in line with the behaviour of ZOOM-C on the client side.
179 Add function ZOOM_scanset_display_term.
181 yaz-client shows scan displayTerm if present.
183 Utility yaz-iconv is now installed by default along with the man page
186 Extend configure check for OpenSSL to use pkg-config where available (such
189 Incorporate patch by Morten Bogeskov which allows a Unix file socket
190 server to specify uid/gid/mask for socket using the format
191 unix:[user=uid,][group=gid,][umask=mask,]file=path
192 If file= is omitted the existing format is assumed, e.g.
194 in which case the mask is 0666 (rw for everybody).
196 Major restructure of YAZ source. All source in libyaz is in src directory.
197 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
198 util (utility programs such as ASN.1 compiler, yaz-marcdump).
200 Added man page for utility yaz-marcdump (used to be called marcdump).
201 yaz-marcdump is installed by 'make install'.
203 Fixed a memory leak in Generic Frontend Server that occurred when decoding
204 of incoming package failed.
206 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
208 Change prototype of odr_perror: add const to message string.
210 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
212 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
213 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
214 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
215 DNS lookup. There should not be any compatibility problems with this
216 assuming that blocking=1 or 0 is used.
218 Fix bad reference in UNIX comstack in function cs_addrstr.
220 Fix for compilation on AIX.
222 The generic front-end server (server/seshigh.c) now supports returning
223 Init diagnostics to the client in User-information-field, in
224 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
229 Allow any CQL relation (not just all,any,exact,scr).
231 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
232 that features the same UI.
234 Implemented command update0 in YAZ client which is equivalent to
235 update but uses old of Ext Update ASN.1.
237 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
238 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
239 Previously no OID was used for this info.
241 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
242 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
243 returns 'malformed search term' otherwise.
245 SortResponse member resultCount now set to NULL in sort handler of
248 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
251 Add three new utility functions for translating OIDs between various
252 formats -- symbolic name such as "Usmarc", minus-1-terminated int
253 arrays and dotted strings such as "1.2.840.10003.9.5.1":
254 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
255 char *oid_to_dotstring(const int *oid, char *oidbuf);
256 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
258 Reverted modifications for ES Update definition for z_IU0Update
259 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
260 is back to YAZ 2.0.2.
262 String value attributes for CCL parser.
264 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
265 which their FirstSearch server returns in Init responses, sometimes
266 carrying useful diagnostic information when Init fails. This has the
267 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
268 "z39.50/oclcui.asn", where its definition is somewhat different from
269 what OCLC document on their web-site, as required to interoperate with
272 Support for anonymous authentication in yaz-client. Use the command
275 * Fix the OID of the Index Data-local "admin" Extended Service from
276 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
277 the 1000, which indicates a locally-defined OID, was a mistake.
281 Fix CCL directive @case handling so that it affects string match for
282 both CCL keywords and qualifiers.
284 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
285 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
286 Decoder has been updated with ASN.1 changes as listed in
287 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
288 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
289 z_IUUpdate, remains unchanged.
291 ZOOM_record_get may now return a record in a specific character set.
292 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
293 "from" is the character set of record as returned by target. "to" is
294 the character set to be returned. If omitted, "to" is UTF-8.
296 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
298 New ODR utility, odr_getelement, which returns name of element for
299 which encoding/decoding failed.
301 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
302 in cases where a required element was omitted.
304 Bug fix: some MARC8 sequences were not converted.
306 New ZOOM option "step" which specifies number of records to be
307 retrieved in one chunk. Used in conjunction with "start" and "count".
309 SRW support for yaz-client. Use scheme http: to use it, e.g.
312 yaz-client no longer does (un)intelligent character set conversions
313 by default. Can be enabled with charset and marc_charset commands.
315 xmalloc trace fix for 64-bit systems such as DEC alpha.
317 Solaris 2.6 compile fix.
319 New function, cql_strerror() translates SRW error codes, as returned
320 by cql_transform_error(), into human-readable English strings. Used
321 in yaz-client diagnostics when appropriate.
323 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
324 converts it into a type-1 query which is sent to the server. This
325 makes CQL available for use with all Z-servers, as opposed to the tiny
326 minority that can handle CQL queries themselves.
330 New Debian package layout similar to the Redhat Package layout.
332 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
333 and search result respectively.
337 Redhat package is now several packages: libyaz (runtime libraries),
338 libyaz-devel (development and documentation, and yaz (utility programs).
339 Package spec file by Morten Bøgeskov.
341 New member 'schema' in struct bend_fetch_rr which the name of requested
342 schema (SRW/SRU) for record (or NULL if none was given). The fetch
343 handler MAY set this to reflect the schema of the returned record.
345 New member 'display_term' in struct scan_entry. GFS now sets member entries
346 and allocates scan entries to be filled by user scan handler. In previous
347 version, entries member was allocated by the scan handler. That still works,
348 but the GFS will ignore member display_term - assuming it was NOT set by
349 the handler. The fact that the GFS now allocates the entries both allows
350 for new members and makes a scan handler easier to write.
352 Fix CQL lex buffer overflow.
354 SRW/SRU recordPacking. For SRW default recordPacking is string. For
355 SRU default recordPacking is string.
357 SRU protocol support for frontend server.
359 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
361 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
363 Added scan for the ZOOM shell (zoomsh).
367 * String Identifers for Schemas (Amendment 5).
368 http://lcweb.loc.gov/z3950/agency/amend/am5.html
369 Old definition for schema
370 Odr_oid *schema; /* OPT */
375 Z_InternationalString *uri;
376 #define Z_Schema_oid 1
377 #define Z_Schema_uri 2
380 * resultCount parameter to Sort Response (Amendment 1).
381 http://lcweb.loc.gov/z3950/agency/amend/am1.html
383 Support for SRW 1.0 over HTTP. This is an optional feature and
384 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
387 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
388 on the same port. SRW SearchRetrieveRequests are mapped
389 to bend_init,bend_search,bend_fetch,bend_close.
391 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
393 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
394 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
396 ZOOM connections are SRW based if schem http is used for hostname
397 in connect, e.g. z = ZOOM_connection_new("http://myserver");
398 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
400 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
401 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
402 distance=n, order=true/false, relation=le, prox unit=word. If
403 n is omitted, distance 1 is used.
405 Fixed problem with C compiler include path in wrong order.
407 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
408 on Solaris. Patch from Ko van der Sloot.
410 New MARC decode API. All new functions operate on a yaz_marc_t
411 handle. The most important new functions are: yaz_marc_create,
412 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
413 decode and destroy respectively. Decoder can produce formats
414 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
415 include/yaz/marcdisp.h.
417 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
418 to UTF-8, UCS-32, wchar_t or Latin-1.
420 * Prototypes for yaz_iconv_-functions moved to separate header
421 include/yaz/yaz-iconv.h.
423 Make a few private functions 'static' in unix.c. This prevents
424 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
426 For ZOOM connection, the options targetImplementation{Id,Name,Version}
427 are set when Init Response is received.
429 New function ZOOM_connection_error_x similar to ZOOM_connection_error
430 but returns diagnostic set as well.
432 New function yaz_strerror which is a portable wrapper for
433 strerror/strerror_r/GetLastMessage.
435 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
436 is returned for MARC. If type is "oai", then OAI MARC is returned.
438 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
443 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
445 Fix bad race conditions on SIGTERM and terminate gracefully in
448 Move retrieval (data1) module to Zebra since nobody seems to be
451 Add GRS-1 render for ZOOM using same format as yaz-client.
455 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
457 Fix broken ESpec handling in data1 module.
459 SGML reader parses comments and makes them part of the data1 tree.
461 Added several type casts so that YAZ compiles as C++ code.
463 ZOOM didn't handle PDU encoding failures properly.
465 Added more Bib-1 diagnostics (approved extensions).
467 GNU configure: better check for iconv.
469 More portable use of accept, getpeername. Check for socklen_t. Use
470 int/size_t if socklen_t is not defined.
474 PQF parser rejects bad queries - including those with extra
475 characters in them. PQF parser used to silently ignore that.
476 Cleaner API for PQF added, which allows you to get detailed
477 error information for bad queries (see yaz/pquery.h).
479 Fixed bug in ZOOM_record_get for type "database".
481 Implemented mini iconv library supporting conversions between
482 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
484 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
488 Fixed ZOOM C record cache so that preferredRecordSyntax and
489 elementSetName is used to check for already fetched records.
493 Added three members in bend_initrequest structure to facilitate
494 character set negotiation.
496 Fixed a bug in frontend server that could cause indefinite
497 loops under rare conditions.
499 Revised character set utilities (charneg.h) so that encoding
500 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
502 For PQF, directive @term <type> sets term type for Scan/Search.
503 Here <type> is general, string, numeric, null. The term type
504 is inherited - just like @attr.
506 New call odr_set_charset that sets character set conversion for
507 international-strings on a ODR stream. Prototype is:
508 int odr_set_charset(ODR o, const char *to, const char *from);
509 The InternationalString is still represented as C string in YAZ
510 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
511 won't). On the protocol level, you can use any encoding.
513 Support for UNIX sockets in ZOOM.
515 Solaris recv sometimes returns errno == ENOENT. It is treated as
516 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
518 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
519 both client and server. Code by Morten Bøgeskov.
523 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
524 that they can be used directly from Visual Basic. You must recompile
525 your windows APP if you're using ZOOM.
527 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
528 Commands "lang" and "charset" sets language and character set respectively.
529 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
530 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
532 Attributes from multiple CCL fields may be OR'ed rather than merged
533 using directive "@field or". Fields are still merged by default -
534 equivalent to "@field merge".
536 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
539 Fixed bug in zget for parameter ExtendedServicesResponse.
545 Added PQF feature: '@attr type=value' may be written as '@type=value'.
547 Client displays USR.1:SearchResult-1 (hits per term).
549 Additional Search Info for search in Generic Frontend Server.
551 Fixed CCL parsing of "field=s".
553 WIN32 installer - using the excellent NSIS software from nullsoft.
555 Fixed CCL parsing of "field = - <number>".
557 Added function yaz_marc_decode that decodes MARC for line mode
558 display or XML (similar to that used by JZKit).
560 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
561 Z39.50. But ISO/ILL was, however.
563 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
564 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
566 http://lcweb.loc.gov/z3950/agency/amend/am2.html
567 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
571 New YAZ client features: Command completion and new commands:
572 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
573 Code provided by Jacob Poulsen.
575 New call oid_trav, that visits all registered OIDs via callback.
577 Function ZOOM_record_get now returns const char pointer rather than
578 void pointer. It saves a lot of type casts.
580 For YAZ client, command "auth" now allows you to set authentication
581 in IdPass style. It is enabled when three tokens are given - order
582 is user, group and password.
584 Fix memory leaks in MARC record handling for ZOOM.
586 New option for YAZ client, -k <kilobytes> that sets
587 maximum record size. Similar to -k option for generic frontend
588 server and yaz-ztest.
590 More fixes for scan. Non-zero stepSize handled. OID's fixes.
592 Prefix query parser reports "fail" when bad attribute set is given.
594 Fix in MARC decoder. Proximity logging. Fix for attribute set
595 in scan handler for server. Patches by Shigeru Ishida.
597 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
600 Configure option --with-openssl=<dir> now works when a directory is
601 specified. Patch provided by Morten Bøgeskov.
603 New option for YAZ client, -u <auth>, that sets authentication.
605 ZOOM fix: error information was sometimes "missing", since error
606 was cleared/reset too when it shouldn't.
608 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
612 Scan for ZOOM API. New object ZOOM_scanset. New functions
613 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
614 ZOOM_scanset_destroy.
616 New ZOOM function, ZOOM_connection_last_event, that returns type
617 of last event (such as "receive data", "send data", "apdu received",
620 New ZOOM option, schema, that specifies schema for retrieval.
622 New CCL feature. Qualifiers can be aliases for one or more
623 other qualifiers (if more than one is given, OR is used).
625 ZOOM uses named result sets if target supports it.
627 Two new YAZ client commands: . (dot, which sources a script of YAZ
628 client commands), and ! (to execute shell command.). Implemented
631 Working on Debian packages.
635 YAZ client enables named result sets only if target supports it.
637 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
639 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
640 with key="host" to get same result.
642 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
643 Function Z3950_resultset_record(s) returns references to records
644 "owned" by resultset. To become owner use Z3950_record_clone.
646 Function z_ext_record handles Extended Services. Thanks to
651 CCL Parser fix: ignore token comma when dealing with and-lists.
653 Documentation updates for COMSTACK.
655 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
656 Changed prototype Z3950_records. For some functions, int parameters
657 were changed to size_t.
659 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
662 New MARC decode/display function, marc_display_exl, which properly rejects
663 non-ISO2709 records. YAZ client uses it.
667 Fix bug: local attribute set wasn't set correctly in PQF strings.
671 * Old Z39.50 codecs no longer supported.
673 Added ZOOM C binding. See http://zoom.z3950.org/
675 Renamed states for COMSTACKs to avoid confusion with events.
677 Implemented cs_look and proper cs_rcvconnect.
679 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
681 Configure detects POSIX threads on OpenBSD.
683 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
684 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
686 When error is returned from present handler, non-surrogate diagnostic
687 is returned in present response (and fetch handler is no longer called).
689 * Minor adjustments to pquery parser (PQF). Token characters may be
690 escaped by using backslash (C-style).
692 PQF parser allows string attribute values to be specified. For @attr,
693 non-numeric characters after the equal-sign are treated as strings
694 (e.g. @attr 9=title).
696 CCL trunction character may be defined (@truncation in file)
698 * function zget_ExtendedServicesRequest sets waitAction to
699 waitIfPossible (was wait).
701 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
704 CCL operator names may be set in field definition files (CCL_bibset).
705 See ccl/bib1 for an example.
707 Fixes in ASN.1 compiler for C++ compatibility.
709 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
710 and "op_or" to avoid conflict with C++.
712 Fixed problem with GNU readline detection on Redhat 7.0.
714 Added step-size for Scan backend handler.
716 Fixed bug that made the frontend server crash when no attribute
717 set was specified for scan.
719 Front-end server automatically switches to original working directory
720 when installed as an NT service. Previously -w had to be specified to
723 Added extended attributes for retrieval module (data1), so that data1
724 records carry d1_readXML/SGML attributes. d1_read also supports
725 null-data rules ( <tag/>)
727 On UNIX when POSIX threads are available, a separate library libyazthread
728 is created. Programmers should link with that library and the yaz library
729 when using threads. The reason for the split was that some applications
730 on Linux, such as Apache, doesn't work well when using shared objects that
733 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
734 (or any frontend server) in SSL mode by specifying ssl: followed by
735 address. Only tested on UNIX.
737 Added feature for CCL module. Virtual structure s=al or s=ol generates
738 and-list and or-list respectively instead of phrase search.
742 * Added prefix "yaz_" for the functions log_init.., log_file.. and
743 log_mask_str. This was done to avoid name conflicts with other libraries
744 (such as other PHP extensions).
746 Added raw OID member for preferred record syntax (request_format_raw)
747 and returned record syntax (output_format_raw) for backend fetch method.
749 Config file yaz-config now accepts options so that it returns specific
750 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
752 Shared library support for UNIX using GNU libtool.
754 * Modified backend interface. Request/Response struct's replaced by
755 one read/write C struct. For example bend_fetchrequest and
756 bend_fetchresult have been replaced by single bend_fetch_rr struct.
757 Every handler - even search has to be registered in bend_init
758 handler. This means that the YAZ library no longer refers to
759 external functions and it makes it possible to make the whole
760 thing a single DLL/SO.
762 Added Segment handler for backend server.
764 Added Zmbol/Zebra administrative functions to YAZ client.
766 Threaded frontend server on UNIX (when POSIX Threads are available).
767 Starting the server with option -T enables multi-threading.
771 Added configure option --enable-comp/disable-comp to control use
772 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
773 located in sub directory asn.
775 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
776 in ${exec_prefix}/bin along with the other programs yaz-client and
779 GNU automake used to maintain makefiles.
783 Changed retrieval module so that we can load records with no abstract
784 syntax defined. Tagpaths in these records are fully composed of string
787 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
791 On UNIX, the generated makefile now supports a proper 'make install'.
792 The prefix can be set via GNU configure to set the install location
793 (default is /usr/local).
795 * YAZ programs client and ztest were renamed to yaz-client and
796 yaz-ztest to avoid conflicts when users install YAZ in "standard"
797 locations, such as /usr/bin,/usr/local/bin,etc.
799 * YAZ Header files were moved from include to include/yaz. YAZ Header
800 files are referred to as include <yaz/log.h> rather than <log.h>.
801 The YAZ include path (-I ..) is therefore the same as before. Programmers
802 should update their #include statements or use -Ipath/include/yaz
803 instead. The main motivation for doing this change is that YAZ header files
804 can be installed in "standard" locations /usr/include,/usr/local/include
805 without introducing conflicts, since ALL YAZ header files are stored
806 in subdirectory yaz (under /usr/include for example).
808 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
809 rather than project/workspace files. We switched because project files
810 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
813 Changed name of logging function, logf, to yaz_log, to prevent name
814 clash with some math-log functions. The YAZ header log.h defines logf
815 to yaz_log (#define) so there should be no incompatibilities by this
818 Added bend_start/bend_stop handlers for server. These handler are
819 called on start/stop of server. For windows they are called whenever
820 a service is started/stopped.
822 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
823 a fairly small ASN.1 compiler written in Tcl. The compiler is located
824 in util/yc.tcl. The auto-generated C code structures are, in a few
825 cases, incompatible with the old decoders. There are differences in the
826 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
827 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
828 The preprocessor variable ASN_COMPILED is defined when the compiled
829 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
830 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
831 wish to use the old encoders/decoders you can specify --disable-yc
834 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
835 version so that it supports both new - and old version of DB Update
837 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
838 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
839 change. The name parameter can be set to 0 in which no name is specified
840 for the construction. The macros odr_implicit and odr_explicit sets name
841 parameter to zero for the construction involved. New macros
842 odr_implicit_tag and odr_explicit_tag are similar to the others,
843 except that a name parameter is added. For programmers' that don't use
844 ODR they probably only need to change the call to z_APDU and z_External.
846 Added access control facility by interfacing the TCP wrapper library.
847 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
848 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
849 name of the daemon and enables the access control as specified in
850 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
852 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
853 den Dool <H.M.vdnDool@kub.nl>.
855 Added reference ID parameter to most functions in server API - refer
856 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
858 Changed name of ccl library to libccl.a (was ccl.a).
860 Fixed bug in decoder for Explain (Category TargetInfo).
862 Added support for GNU readline in client. Thanks to Jacob Poulsen
863 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
865 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
866 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
867 IMPLEMENTATION! This change was made to the development version before
868 the ZIG decided to retract the amendment. If any users MUST be
869 compatible with the original Update definition, PLEASE CONTACT US, and
870 we will include a separate definition corresponding to the old Update
871 ES. Note that because of the change to the ASN.1 of the
872 TaskPackageRecordStructure we cannot define a single structure that
873 will support both versions.
875 * Added const modifier to buffer parameter for some ODR/BER encoding
876 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
877 completeWAIS, odr_dumpBER.
879 Fixed bug in client.c which caused a crash when a scanResponse didn't
880 contain positionOfTerm.
882 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
883 * will cause an error in a client if a non-YAZ target sends both a
884 * list of Scan entries and non-surrogate diagnostics.
886 Retrieval module enhancements. Tag sets may be typed in the reference
887 to it. From the .abs-file the "tagset" directive takes a third optional
888 integer type for the tag set referenced. From a .tag-file the "include"
889 directive takes a third optional type as well. The old "type" directive
890 in the tag set itself is still recognized but acts as the default type
893 Backend interface change. Individual Scan terms returned from bend_scan
894 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
895 in include/backend.h.
897 Retrieval module enhancements. Multiple tag sets and attribute sets may
898 be specified in abstract syntax specs. Revised the error/warning for
899 logging messages reported by the retrieval module when reading the
902 Object Identifier system (oid_..) changed. The API is backwards
903 compatible but the oid-routines now allocates new OID's when needed.
904 Raw OID's may be specified in oid_getvalbyname.
906 YAZ now uses GNU configure to generate Makefile(s).
908 * Minor changes in some of the member names of DeleteResultSetRequest and
909 DeleteResultSetResponse. See include/proto.h.
911 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
912 and added member 'languages' in TargetInfo (which was missing).
914 Changed the way attribute sets are handled in the retrieval
915 module. These are now cached, just like the abstract syntaxes
918 Changed YAZ so that it links with compiled ASN.1.
920 Added Explain-schema definitions and mapping routines. The following
921 Explain categories have been implemented: AttributeDetails,
922 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
924 Fixed minor bug in Windows version of Server Library.
926 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
928 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
930 Added EXTERNAL: UNIverse Resource Report (non-standard).
932 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
933 ENUMERATED and SET OF.
935 * Added 'const' to some of the char pointer arguments for the
936 functions, data1_read_node, data1_getelementbytagname,
937 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
940 Fixed bug in data1_insert_taggeddata - the last_child member of
941 parent wasn't initialised.
943 * Changed data1_read_record and data1_read_node so that the supplied
944 "SGML"-buffer is read-only. In particular the resulting data1 - tree
945 doesn't refer to any parts of the "SGML"-buffer.
947 Fixed bug in server library (Windows version of statserv_remove).
949 * Changed code so that it compiles as C++. The type definition
950 of Odr_fun which is a member of Odr_arm was changed. The result is,
951 that an explicit typecast is needed for the fun pointer when
952 using Odr_arm - as in:
953 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
955 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
957 Implemented the new structured date and time definition as approved
958 by the ZIG. Added schemaId element to the specificTag in Espec-1
959 (also approved at the last ZIG). Thanks to RVDM.
961 Added some Object identifiers (RVDM).
963 Changed the Update Extended Service (RVDM).
965 Added command "refid" to client which specifies referenceId for
966 the following requests.
968 Implemented extended service handling for server. See ztest.c
969 for an example as well as backend.h. New handlers are registerd
972 * Changed interface for sort in server.
974 Added new members to statserv_options_block. It allows a server
975 to read options from another source than just the command line. Thanks
976 to Charles Woodfield.
978 * Changed definition of Z_Triple in file prt-grs.h - member boolean
979 renamed to zboolean. Some C++ compilers complained about the name.
981 Minor changes to gils.abs. Added index 's' (sort) on title
982 and date/time-last-modified.
986 Fixed bug in server library regarding inetd mode (-i). This bug
987 was introduced by release 1.4.
991 Added sort facility in client and backend server interface.
993 Fixed problem with dependencies in Makefile(s).
995 Fixed bugs for encoders/decoders of extended services and
998 Implemented sub-tree feature for schemas. Sub-trees are
999 referenced in *.abs-files. See explain.abs for an example
1000 of the use of this feature.
1002 Modified bib1.att; local attributes for ANY didn't include
1003 ANY itself (only affects use of the retrieval module).
1005 Fixed bug in plain SGML reader in function data1_read_node:
1006 tags with prefix "var" was incorrectly interpreted as variants.
1008 Added feature "sub-schemas" to enable references to - and definitions
1009 of - group of elements.
1011 * Removed member parent from type data1_element (in data1.h).
1013 Implemented function odr_nullval() that returns the value of
1016 * Removed member num_children from data1_node (in data1.h).
1018 Made NT service interface part of the server library. The
1019 function statserv_main uses the NT service when required and
1020 calls the statserv_start / statserv_close routines.
1022 Routine zget_SearchRequest and zget_PresentRequest fills
1023 resultSetName/Id member with "default" instead of "Default".
1025 Fixed memory leak in server. Request queue member wasn't freed.
1027 Fixed nmem_exit so that memory is freed.
1031 Revised the CCL parser utility to be thread safe.
1033 Added function, oid_ent_to_oid, to replace the function
1034 oid_getoidbyent, which is not thread safe.
1036 * Added nmem_init and nmem_exit to initialize and release
1037 NMEM resources. Function nmem_init should be called once in the
1038 initial thread before NMEM/ODR is used. statserv.c and client.c
1039 have been changed accordingly. The change was necessary to make
1040 NMEM thread safe. The NMEM memory pool is shared amongst threads
1041 in a process. Unix-based applications will still work fine without
1044 Added NT Services interface for the the Z39.50 (statserv) Server.
1045 Refer to the ztest.c source on the usage.
1047 Windows 95/NT port using MSVC5.0. Project files are included in the
1050 * Defined new 'global' handle for the retrieval (data1) system. The
1051 new handled, data1_handle, describes the state of the data1 system.
1052 This handle is passed as first argument to virtually all
1053 data1 related routines. The functions data1_create and data1_destroy
1054 creates and destroys a data1 handle respectively.
1056 Added ODR encode stream member to all backend request structures
1057 init, search, scan etc. This stream should be used to allocate all
1058 memory used for the response when thread safe operation is needed.
1060 Changed the comstack utility, cs_addstr, to be thread safe. The
1061 returned hostname string returned by the function is now part the
1064 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1065 function. The cs_straddr takes a COMSTACK handle as argument, so this
1066 function must be used after cs_create and before bind/connect.
1067 This function is thread safe.
1069 Moved test server to 'ztest' directory - generic server code still
1070 in 'server' directory.
1072 Made prefix query (pquery.c) utility thread safe.
1074 Added new function modifier YAZ_EXPORT to 'export' public DLL
1075 functions when using windows (see include/yconfig.h).
1077 Added definitions to the OID database (util/oid.c) (RVDM).
1079 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1081 Added call to ccl_rpn_delete in client program.
1083 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1084 release of RPN structure.
1086 Added support for C++, headers uses extern "C" for public definitions.
1087 With input from RVDM.
1089 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1090 Thanks to Ronald van der Meer (RVDM).
1092 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1094 Added support for private extensions to the OID database
1095 (oid_setprivateoids()). Thanks to RVDM.
1097 Added optional, physical ANY (key replication)
1099 Fixed null-reference problem in GRS-1 output filter.
1101 Proximity operator added to Prefix Query Format (PQF).
1103 In test client command "base" accepts multiple databases.
1105 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1109 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1111 Smallish bug-fixes in the new encoders/decoders (explain).
1113 Bug fixed in DeleteRequest.
1115 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1117 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1119 Added SOIF syntax (using private OID for now) to retrieval module and client.
1121 Added Update extended service.
1123 Added SearchResult-1 additional info structure.
1125 Added optional CCL (ISO8777) interpreter as separate module. Available
1128 --- 1.2 1996/6/10 (1st anniversary release)
1130 Added Summary record syntax. Lightly tested.
1132 Added OPAC record syntax. Untested.
1134 Added ResourceReport service encoders/decoders. Untested.
1136 Fixed bug in z_Unit - wrong tagging on unitSystem.
1138 Fixed bug in the DiagRecs decoder.
1140 Added options for max PDU size and session timeout to frontend-server.
1142 Added documentation of query-language parsers and other supporting utilities.
1144 [frontend-server] Added Attribute set to the bend_scanrequest API.
1146 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1147 surrogate diagnostics were generated.
1149 [retrieval] Allow multiple local values for attribute.
1151 [retrieval] Allow multiple attributes per element in .abs files. index type.
1153 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1155 --- 1.1pl2 1996/4/10
1157 Minor changes, mostly specific to Zebra's requirements (retrieval)
1161 Repaired bug in frontend server when running multiple listening
1162 endpoints in dynamic mode.
1164 z_External() now won't break if a known, ASN.1 value comes encapsulated
1165 in an octet-string. The value will pass through unmodified in an Odr_oct.
1167 Added a bit of code to the demo client to decode & display
1168 ASN.1-structured records represented in the octet-aligned branch of
1169 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1171 Added z_ext_getentbyref() to the ASN module. Doc updated.
1173 * Completed the SCAN definition in the ASN module. This may break SCAN
1174 code based on older YAZ-versions at compile-time. The fix is easy -
1177 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1178 under the SCAN definition. Remember to initialize this, server-people.
1180 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1181 that this does not extend to ODR and ASN.
1183 Comstack allows insertion of established socket (primarily for
1184 inetd-operation of servers). Doc updated.
1186 Front-end server can now start from the inetd in TCP mode. Doc
1189 --- 1.0pl4 1996/1/24
1193 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1194 the rank and record number.
1196 Adjustments to the frontend server.
1198 Fixed diagnostic BER dumper. It ignored the file argument.
1202 Various changes to retrieval module.
1204 Changed the union discriminators of the protocol files from enums to
1205 ints paired with #defines.
1207 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1210 *Changed operator in the RPN structure to 'roperator', again to avoid a
1213 Fixed problems in Explain decoders/encoders.
1215 --- 1.0pl2 1995/12/6
1217 Memory bug in log module fixed.
1219 --- 1.0pl1 1995/12/5
1221 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1223 Bug in Explain DatabaseInfo module fixed.
1225 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1229 The shift to v1.0 signals that we now consider the *core* functionality
1230 of YAZ reasonably stable (the core being more or less equivalent to
1231 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1232 tested (Explain not at all - though that will happen soonish).
1234 Minor changes to code to support Windows port.
1236 Various minor changes after we're getting to use GRS-1 & co. more.
1238 Added Espec-1 format.
1240 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1241 of the protocol and it cannot be selected when encoding (maps into 'string'
1242 when decoding). Needed to talk to some servers.
1244 Demo client can request simple element set names.
1246 Added Diagnostic Format encoders/decoders.
1248 Added simple Close handling to frontend server (no hooks for resource
1249 reporting yet), and demonstration client.
1251 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1253 --- 1.0b3 1995/08/24
1255 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1256 handled incorrectly when records were requested in the searchResponse. This
1257 will only affect you if you use the frontend-server.
1259 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1260 Test-client will ask for and print GRS1. Ztest will return dummy records
1263 Added Explain encoders/decoders to the service-level API. Untested.
1265 Added Extended Services: Item Order encoders and decoders to the Service-
1266 level API. Untested. We could use a recent copy of the pertinent bits
1267 of the ILL protocol to add those bits.
1269 Added diagnostic format 1 encoders/decoders to the service-level API.
1272 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1273 odr_cons.c, which causes a more correct output.
1275 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1276 was always set to 0 when no records were requested in the searchRequest.
1278 * Added better external-handling. This shouldn't harm old code that
1279 *encodes* externals. It can break code that looks for a
1280 'single-ASN1-type' representation, since those types that are known
1281 are now decoded immediately. Look at the SUTRS sample code in
1282 seshigh.c and client.c. Documentation updated.
1284 Handling of structured records in bend_fetchresponse. Length -1 marks
1285 structured record, type is deduced from format field.
1287 --- 1.0b2 1995/06/27
1288 Fairly quick maintenance release to add SUTRS support.
1290 Fixed handling of SUTRS records in the demonstration client.
1292 * Added format field to the bend_fetchrequest and bend_fetchresponce
1293 structures of the backend API (frontend server). When the record is
1294 returned, the value of the format field is mapped to an OID. The
1295 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1296 of the record. The special value VAL_NONE in the bend_request means
1297 that no specific format was requested by the client. Documentation
1298 updated accordingly. Test server (ztest) will return a fixed dummy
1299 SUTRS record if your client requests SUTRS.
1301 Documentation updated accordingly.
1303 You can now set external libraries and RANLIB support in the top-level
1307 First public release.
