29 --- 2.0.16 2004/03/16 Debian only
31 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
34 Update CQL parser to use new CQL 1.1 modifiers for booleans and
41 Another fix for decoding of XML packed records.
45 Fixes for Chunked encoding. White space not ignored after length spec.
47 Update NS and use default NS for SRW diagnostic elements.
51 Implement ZOOM_resultset_cache_reset which resets record cache.
53 Implement ZOOM_resultset_sort which sorts a result set.
55 Implement chunked HTTP transfer.
57 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
61 Added member 'schema' to bend_explain_rr structure so that backend
62 can specify explain record identifier. Defaults to Zeerex 2.0.
64 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
68 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
71 Added init command for yaz-client which sends "extra" init request.
73 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
74 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
76 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
78 Make ZOOM error code for "invalid query".
80 Fixed compilation for SSL which wasn't properly enabled for all platforms.
84 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
87 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
89 Added option -p <file> to make Generic Frontend Server to write PID file.
91 Added option -D to put Generic Frontend Server in background on its own.
93 Make ZOOM C recognize option "password". If unset, "pass" is used
94 (for backwards compatibility).
96 Fixed a bug in Generic Frontend Server that could make it crash if a
97 client sets characterSetNegotation bit, but didn't pass negotiation stuff
100 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
101 Must be issued before open, in order to be in effect.
103 --- 2.0.9-6 2004/01/12 Debian/Windows
105 Make the SRU server more picky WRT unknown params, etc.
107 Bug fix: ZOOM scan response didn't return displayTerm - when present.
109 New YAZ client command, options, that sets Z39.50 options.
111 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
112 options from a string of tokens (one token for each option bit).
114 Update SRW diagnostic code messages.
116 --- 2.0.9-5 2004/01/07 Debian/Windows

126 Fix a bug with decoding of XML packed records.
128 --- 2.0.9-2 2004/01/05 Debian only
130 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
132 Fix bug in SRW/SRU diagnostics decoding.
136 Fixed bug in Generic Frontend Server which could drop records exceeding
137 preferred message size. Reported and fixed by Irina Dijour.
139 Fixed calculation of package size for structured records in Generic
140 Frontend Server. Reported and fixed by Irina Dijour.
142 Fixed namespace for SRW/SRU diagnostics.
144 Fixed SEGV in yaz-client that occured for HTTP connection errors.
148 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
149 this version is incompatible with version 1.0 and older YAZ SRW/SRU
152 CQL changes to reflect recent changes to the specification:
153 * Documentation talks about context sets instead of index sets.
154 * Documentation talks about indexes instead of qualifiers.
155 * The CQL-to-PQF transformer's configuration file now uses
156 "index.set.name = <attributes>" instead of the old form
157 "qualifier.set.name = <attributes>". (Both forms are still
158 understood but the latter is deprecated.)
159 * CQL terms with no explicit index specified are now interpreted as
160 cql.serverChoice instead of srw.serverChoice (which of course
161 behaves exactly the same.)
165 MARC conversion can now generate ISO2709 output in another
166 character set. yaz-marcdump uses this facility if you invoke it
169 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
170 functions from there can be used from C++.
174 Frontend server now transfers memory from decoded packages to stream
177 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
178 references to show up.
180 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
181 the ZOOM Abstract API. The older names for the same options are still
182 also supported for the benefit of old applications.
184 ZOOM-C supports "implementationId" and "implementationVersion" options
185 to go along with "implementationName". These allow the user code to
186 specify identification strings to be sent to servers.
187 Add OID for the new ExtLite attribute set.
189 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
190 as requested/supplid by Ere Maijala <ere@atp.fi>
192 For generic frontend server, reverse the order of
193 "toolkit-supplied / application-supplied" strings sent as implementationId,
194 Name and Version. Also, remove the spaces around the slash. This brings
195 the GFS in line with the behaviour of ZOOM-C on the client side.
197 Add function ZOOM_scanset_display_term.
199 yaz-client shows scan displayTerm if present.
201 Utility yaz-iconv is now installed by default along with the man page
204 Extend configure check for OpenSSL to use pkg-config where available (such
207 Incorporate patch by Morten Bogeskov which allows a Unix file socket
208 server to specify uid/gid/mask for socket using the format
209 unix:[user=uid,][group=gid,][umask=mask,]file=path
210 If file= is omitted the existing format is assumed, e.g.
212 in which case the mask is 0666 (rw for everybody).
214 Major restructure of YAZ source. All source in libyaz is in src directory.
215 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
216 util (utility programs such as ASN.1 compiler, yaz-marcdump).
218 Added man page for utility yaz-marcdump (used to be called marcdump).
219 yaz-marcdump is installed by 'make install'.
221 Fixed a memory leak in Generic Frontend Server that occurred when decoding
222 of incoming package failed.
224 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
226 Change prototype of odr_perror: add const to message string.
228 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
230 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
231 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
232 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
233 DNS lookup. There should not be any compatibility problems with this
234 assuming that blocking=1 or 0 is used.
236 Fix bad reference in UNIX comstack in function cs_addrstr.
238 Fix for compilation on AIX.
240 The generic front-end server (server/seshigh.c) now supports returning
241 Init diagnostics to the client in User-information-field, in
242 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
247 Allow any CQL relation (not just all,any,exact,scr).
249 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
250 that features the same UI.
252 Implemented command update0 in YAZ client which is equivalent to
253 update but uses old of Ext Update ASN.1.
255 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
256 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
257 Previously no OID was used for this info.
259 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
260 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
261 returns 'malformed search term' otherwise.
263 SortResponse member resultCount now set to NULL in sort handler of
266 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
269 Add three new utility functions for translating OIDs between various
270 formats -- symbolic name such as "Usmarc", minus-1-terminated int
271 arrays and dotted strings such as "1.2.840.10003.9.5.1":
272 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
273 char *oid_to_dotstring(const int *oid, char *oidbuf);
274 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
276 Reverted modifications for ES Update definition for z_IU0Update
277 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
278 is back to YAZ 2.0.2.
280 String value attributes for CCL parser.
282 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
283 which their FirstSearch server returns in Init responses, sometimes
284 carrying useful diagnostic information when Init fails. This has the
285 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
286 "z39.50/oclcui.asn", where its definition is somewhat different from
287 what OCLC document on their web-site, as required to interoperate with
290 Support for anonymous authentication in yaz-client. Use the command
293 * Fix the OID of the Index Data-local "admin" Extended Service from
294 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
295 the 1000, which indicates a locally-defined OID, was a mistake.
299 Fix CCL directive @case handling so that it affects string match for
300 both CCL keywords and qualifiers.
302 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
303 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
304 Decoder has been updated with ASN.1 changes as listed in
305 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
306 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
307 z_IUUpdate, remains unchanged.
309 ZOOM_record_get may now return a record in a specific character set.
310 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
311 "from" is the character set of record as returned by target. "to" is
312 the character set to be returned. If omitted, "to" is UTF-8.
314 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
316 New ODR utility, odr_getelement, which returns name of element for
317 which encoding/decoding failed.
319 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
320 in cases where a required element was omitted.
322 Bug fix: some MARC8 sequences were not converted.
324 New ZOOM option "step" which specifies number of records to be
325 retrieved in one chunk. Used in conjunction with "start" and "count".
327 SRW support for yaz-client. Use scheme http: to use it, e.g.
330 yaz-client no longer does (un)intelligent character set conversions
331 by default. Can be enabled with charset and marc_charset commands.
333 xmalloc trace fix for 64-bit systems such as DEC alpha.
335 Solaris 2.6 compile fix.
337 New function, cql_strerror() translates SRW error codes, as returned
338 by cql_transform_error(), into human-readable English strings. Used
339 in yaz-client diagnostics when appropriate.
341 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
342 converts it into a type-1 query which is sent to the server. This
343 makes CQL available for use with all Z-servers, as opposed to the tiny
344 minority that can handle CQL queries themselves.
348 New Debian package layout similar to the Redhat Package layout.
350 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
351 and search result respectively.
355 Redhat package is now several packages: libyaz (runtime libraries),
356 libyaz-devel (development and documentation, and yaz (utility programs).
357 Package spec file by Morten Bøgeskov.
359 New member 'schema' in struct bend_fetch_rr which the name of requested
360 schema (SRW/SRU) for record (or NULL if none was given). The fetch
361 handler MAY set this to reflect the schema of the returned record.
363 New member 'display_term' in struct scan_entry. GFS now sets member entries
364 and allocates scan entries to be filled by user scan handler. In previous
365 version, entries member was allocated by the scan handler. That still works,
366 but the GFS will ignore member display_term - assuming it was NOT set by
367 the handler. The fact that the GFS now allocates the entries both allows
368 for new members and makes a scan handler easier to write.
370 Fix CQL lex buffer overflow.
372 SRW/SRU recordPacking. For SRW default recordPacking is string. For
373 SRU default recordPacking is string.
375 SRU protocol support for frontend server.
377 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
379 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
381 Added scan for the ZOOM shell (zoomsh).
385 * String Identifers for Schemas (Amendment 5).
386 http://lcweb.loc.gov/z3950/agency/amend/am5.html
387 Old definition for schema
388 Odr_oid *schema; /* OPT */
393 Z_InternationalString *uri;
394 #define Z_Schema_oid 1
395 #define Z_Schema_uri 2
398 * resultCount parameter to Sort Response (Amendment 1).
399 http://lcweb.loc.gov/z3950/agency/amend/am1.html
401 Support for SRW 1.0 over HTTP. This is an optional feature and
402 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
405 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
406 on the same port. SRW SearchRetrieveRequests are mapped
407 to bend_init,bend_search,bend_fetch,bend_close.
409 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
411 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
412 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
414 ZOOM connections are SRW based if schem http is used for hostname
415 in connect, e.g. z = ZOOM_connection_new("http://myserver");
416 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
418 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
419 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
420 distance=n, order=true/false, relation=le, prox unit=word. If
421 n is omitted, distance 1 is used.
423 Fixed problem with C compiler include path in wrong order.
425 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
426 on Solaris. Patch from Ko van der Sloot.
428 New MARC decode API. All new functions operate on a yaz_marc_t
429 handle. The most important new functions are: yaz_marc_create,
430 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
431 decode and destroy respectively. Decoder can produce formats
432 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
433 include/yaz/marcdisp.h.
435 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
436 to UTF-8, UCS-32, wchar_t or Latin-1.
438 * Prototypes for yaz_iconv_-functions moved to separate header
439 include/yaz/yaz-iconv.h.
441 Make a few private functions 'static' in unix.c. This prevents
442 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
444 For ZOOM connection, the options targetImplementation{Id,Name,Version}
445 are set when Init Response is received.
447 New function ZOOM_connection_error_x similar to ZOOM_connection_error
448 but returns diagnostic set as well.
450 New function yaz_strerror which is a portable wrapper for
451 strerror/strerror_r/GetLastMessage.
453 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
454 is returned for MARC. If type is "oai", then OAI MARC is returned.
456 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
461 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
463 Fix bad race conditions on SIGTERM and terminate gracefully in
466 Move retrieval (data1) module to Zebra since nobody seems to be
469 Add GRS-1 render for ZOOM using same format as yaz-client.
473 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
475 Fix broken ESpec handling in data1 module.
477 SGML reader parses comments and makes them part of the data1 tree.
479 Added several type casts so that YAZ compiles as C++ code.
481 ZOOM didn't handle PDU encoding failures properly.
483 Added more Bib-1 diagnostics (approved extensions).
485 GNU configure: better check for iconv.
487 More portable use of accept, getpeername. Check for socklen_t. Use
488 int/size_t if socklen_t is not defined.
492 PQF parser rejects bad queries - including those with extra
493 characters in them. PQF parser used to silently ignore that.
494 Cleaner API for PQF added, which allows you to get detailed
495 error information for bad queries (see yaz/pquery.h).
497 Fixed bug in ZOOM_record_get for type "database".
499 Implemented mini iconv library supporting conversions between
500 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
502 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
506 Fixed ZOOM C record cache so that preferredRecordSyntax and
507 elementSetName is used to check for already fetched records.
511 Added three members in bend_initrequest structure to facilitate
512 character set negotiation.
514 Fixed a bug in frontend server that could cause indefinite
515 loops under rare conditions.
517 Revised character set utilities (charneg.h) so that encoding
518 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
520 For PQF, directive @term <type> sets term type for Scan/Search.
521 Here <type> is general, string, numeric, null. The term type
522 is inherited - just like @attr.
524 New call odr_set_charset that sets character set conversion for
525 international-strings on a ODR stream. Prototype is:
526 int odr_set_charset(ODR o, const char *to, const char *from);
527 The InternationalString is still represented as C string in YAZ
528 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
529 won't). On the protocol level, you can use any encoding.
531 Support for UNIX sockets in ZOOM.
533 Solaris recv sometimes returns errno == ENOENT. It is treated as
534 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
536 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
537 both client and server. Code by Morten Bøgeskov.
541 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
542 that they can be used directly from Visual Basic. You must recompile
543 your windows APP if you're using ZOOM.
545 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
546 Commands "lang" and "charset" sets language and character set respectively.
547 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
548 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
550 Attributes from multiple CCL fields may be OR'ed rather than merged
551 using directive "@field or". Fields are still merged by default -
552 equivalent to "@field merge".
554 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
557 Fixed bug in zget for parameter ExtendedServicesResponse.
563 Added PQF feature: '@attr type=value' may be written as '@type=value'.
565 Client displays USR.1:SearchResult-1 (hits per term).
567 Additional Search Info for search in Generic Frontend Server.
569 Fixed CCL parsing of "field=s".
571 WIN32 installer - using the excellent NSIS software from nullsoft.
573 Fixed CCL parsing of "field = - <number>".
575 Added function yaz_marc_decode that decodes MARC for line mode
576 display or XML (similar to that used by JZKit).
578 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
579 Z39.50. But ISO/ILL was, however.
581 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
582 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
584 http://lcweb.loc.gov/z3950/agency/amend/am2.html
585 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
589 New YAZ client features: Command completion and new commands:
590 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
591 Code provided by Jacob Poulsen.
593 New call oid_trav, that visits all registered OIDs via callback.
595 Function ZOOM_record_get now returns const char pointer rather than
596 void pointer. It saves a lot of type casts.
598 For YAZ client, command "auth" now allows you to set authentication
599 in IdPass style. It is enabled when three tokens are given - order
600 is user, group and password.
602 Fix memory leaks in MARC record handling for ZOOM.
604 New option for YAZ client, -k <kilobytes> that sets
605 maximum record size. Similar to -k option for generic frontend
606 server and yaz-ztest.
608 More fixes for scan. Non-zero stepSize handled. OID's fixes.
610 Prefix query parser reports "fail" when bad attribute set is given.
612 Fix in MARC decoder. Proximity logging. Fix for attribute set
613 in scan handler for server. Patches by Shigeru Ishida.
615 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
618 Configure option --with-openssl=<dir> now works when a directory is
619 specified. Patch provided by Morten Bøgeskov.
621 New option for YAZ client, -u <auth>, that sets authentication.
623 ZOOM fix: error information was sometimes "missing", since error
624 was cleared/reset too when it shouldn't.
626 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
630 Scan for ZOOM API. New object ZOOM_scanset. New functions
631 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
632 ZOOM_scanset_destroy.
634 New ZOOM function, ZOOM_connection_last_event, that returns type
635 of last event (such as "receive data", "send data", "apdu received",
638 New ZOOM option, schema, that specifies schema for retrieval.
640 New CCL feature. Qualifiers can be aliases for one or more
641 other qualifiers (if more than one is given, OR is used).
643 ZOOM uses named result sets if target supports it.
645 Two new YAZ client commands: . (dot, which sources a script of YAZ
646 client commands), and ! (to execute shell command.). Implemented
649 Working on Debian packages.
653 YAZ client enables named result sets only if target supports it.
655 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
657 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
658 with key="host" to get same result.
660 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
661 Function Z3950_resultset_record(s) returns references to records
662 "owned" by resultset. To become owner use Z3950_record_clone.
664 Function z_ext_record handles Extended Services. Thanks to
669 CCL Parser fix: ignore token comma when dealing with and-lists.
671 Documentation updates for COMSTACK.
673 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
674 Changed prototype Z3950_records. For some functions, int parameters
675 were changed to size_t.
677 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
680 New MARC decode/display function, marc_display_exl, which properly rejects
681 non-ISO2709 records. YAZ client uses it.
685 Fix bug: local attribute set wasn't set correctly in PQF strings.
689 * Old Z39.50 codecs no longer supported.
691 Added ZOOM C binding. See http://zoom.z3950.org/
693 Renamed states for COMSTACKs to avoid confusion with events.
695 Implemented cs_look and proper cs_rcvconnect.
697 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
699 Configure detects POSIX threads on OpenBSD.
701 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
702 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
704 When error is returned from present handler, non-surrogate diagnostic
705 is returned in present response (and fetch handler is no longer called).
707 * Minor adjustments to pquery parser (PQF). Token characters may be
708 escaped by using backslash (C-style).
710 PQF parser allows string attribute values to be specified. For @attr,
711 non-numeric characters after the equal-sign are treated as strings
712 (e.g. @attr 9=title).
714 CCL trunction character may be defined (@truncation in file)
716 * function zget_ExtendedServicesRequest sets waitAction to
717 waitIfPossible (was wait).
719 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
722 CCL operator names may be set in field definition files (CCL_bibset).
723 See ccl/bib1 for an example.
725 Fixes in ASN.1 compiler for C++ compatibility.
727 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
728 and "op_or" to avoid conflict with C++.
730 Fixed problem with GNU readline detection on Redhat 7.0.
732 Added step-size for Scan backend handler.
734 Fixed bug that made the frontend server crash when no attribute
735 set was specified for scan.
737 Front-end server automatically switches to original working directory
738 when installed as an NT service. Previously -w had to be specified to
741 Added extended attributes for retrieval module (data1), so that data1
742 records carry d1_readXML/SGML attributes. d1_read also supports
743 null-data rules ( <tag/>)
745 On UNIX when POSIX threads are available, a separate library libyazthread
746 is created. Programmers should link with that library and the yaz library
747 when using threads. The reason for the split was that some applications
748 on Linux, such as Apache, doesn't work well when using shared objects that
751 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
752 (or any frontend server) in SSL mode by specifying ssl: followed by
753 address. Only tested on UNIX.
755 Added feature for CCL module. Virtual structure s=al or s=ol generates
756 and-list and or-list respectively instead of phrase search.
760 * Added prefix "yaz_" for the functions log_init.., log_file.. and
761 log_mask_str. This was done to avoid name conflicts with other libraries
762 (such as other PHP extensions).
764 Added raw OID member for preferred record syntax (request_format_raw)
765 and returned record syntax (output_format_raw) for backend fetch method.
767 Config file yaz-config now accepts options so that it returns specific
768 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
770 Shared library support for UNIX using GNU libtool.
772 * Modified backend interface. Request/Response struct's replaced by
773 one read/write C struct. For example bend_fetchrequest and
774 bend_fetchresult have been replaced by single bend_fetch_rr struct.
775 Every handler - even search has to be registered in bend_init
776 handler. This means that the YAZ library no longer refers to
777 external functions and it makes it possible to make the whole
778 thing a single DLL/SO.
780 Added Segment handler for backend server.
782 Added Zmbol/Zebra administrative functions to YAZ client.
784 Threaded frontend server on UNIX (when POSIX Threads are available).
785 Starting the server with option -T enables multi-threading.
789 Added configure option --enable-comp/disable-comp to control use
790 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
791 located in sub directory asn.
793 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
794 in ${exec_prefix}/bin along with the other programs yaz-client and
797 GNU automake used to maintain makefiles.
801 Changed retrieval module so that we can load records with no abstract
802 syntax defined. Tagpaths in these records are fully composed of string
805 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
809 On UNIX, the generated makefile now supports a proper 'make install'.
810 The prefix can be set via GNU configure to set the install location
811 (default is /usr/local).
813 * YAZ programs client and ztest were renamed to yaz-client and
814 yaz-ztest to avoid conflicts when users install YAZ in "standard"
815 locations, such as /usr/bin,/usr/local/bin,etc.
817 * YAZ Header files were moved from include to include/yaz. YAZ Header
818 files are referred to as include <yaz/log.h> rather than <log.h>.
819 The YAZ include path (-I ..) is therefore the same as before. Programmers
820 should update their #include statements or use -Ipath/include/yaz
821 instead. The main motivation for doing this change is that YAZ header files
822 can be installed in "standard" locations /usr/include,/usr/local/include
823 without introducing conflicts, since ALL YAZ header files are stored
824 in subdirectory yaz (under /usr/include for example).
826 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
827 rather than project/workspace files. We switched because project files
828 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
831 Changed name of logging function, logf, to yaz_log, to prevent name
832 clash with some math-log functions. The YAZ header log.h defines logf
833 to yaz_log (#define) so there should be no incompatibilities by this
836 Added bend_start/bend_stop handlers for server. These handler are
837 called on start/stop of server. For windows they are called whenever
838 a service is started/stopped.
840 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
841 a fairly small ASN.1 compiler written in Tcl. The compiler is located
842 in util/yc.tcl. The auto-generated C code structures are, in a few
843 cases, incompatible with the old decoders. There are differences in the
844 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
845 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
846 The preprocessor variable ASN_COMPILED is defined when the compiled
847 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
848 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
849 wish to use the old encoders/decoders you can specify --disable-yc
852 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
853 version so that it supports both new - and old version of DB Update
855 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
856 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
857 change. The name parameter can be set to 0 in which no name is specified
858 for the construction. The macros odr_implicit and odr_explicit sets name
859 parameter to zero for the construction involved. New macros
860 odr_implicit_tag and odr_explicit_tag are similar to the others,
861 except that a name parameter is added. For programmers' that don't use
862 ODR they probably only need to change the call to z_APDU and z_External.
864 Added access control facility by interfacing the TCP wrapper library.
865 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
866 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
867 name of the daemon and enables the access control as specified in
868 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
870 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
871 den Dool <H.M.vdnDool@kub.nl>.
873 Added reference ID parameter to most functions in server API - refer
874 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
876 Changed name of ccl library to libccl.a (was ccl.a).
878 Fixed bug in decoder for Explain (Category TargetInfo).
880 Added support for GNU readline in client. Thanks to Jacob Poulsen
881 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
883 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
884 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
885 IMPLEMENTATION! This change was made to the development version before
886 the ZIG decided to retract the amendment. If any users MUST be
887 compatible with the original Update definition, PLEASE CONTACT US, and
888 we will include a separate definition corresponding to the old Update
889 ES. Note that because of the change to the ASN.1 of the
890 TaskPackageRecordStructure we cannot define a single structure that
891 will support both versions.
893 * Added const modifier to buffer parameter for some ODR/BER encoding
894 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
895 completeWAIS, odr_dumpBER.
897 Fixed bug in client.c which caused a crash when a scanResponse didn't
898 contain positionOfTerm.
900 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
901 * will cause an error in a client if a non-YAZ target sends both a
902 * list of Scan entries and non-surrogate diagnostics.
904 Retrieval module enhancements. Tag sets may be typed in the reference
905 to it. From the .abs-file the "tagset" directive takes a third optional
906 integer type for the tag set referenced. From a .tag-file the "include"
907 directive takes a third optional type as well. The old "type" directive
908 in the tag set itself is still recognized but acts as the default type
911 Backend interface change. Individual Scan terms returned from bend_scan
912 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
913 in include/backend.h.
915 Retrieval module enhancements. Multiple tag sets and attribute sets may
916 be specified in abstract syntax specs. Revised the error/warning for
917 logging messages reported by the retrieval module when reading the
920 Object Identifier system (oid_..) changed. The API is backwards
921 compatible but the oid-routines now allocates new OID's when needed.
922 Raw OID's may be specified in oid_getvalbyname.
924 YAZ now uses GNU configure to generate Makefile(s).
926 * Minor changes in some of the member names of DeleteResultSetRequest and
927 DeleteResultSetResponse. See include/proto.h.
929 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
930 and added member 'languages' in TargetInfo (which was missing).
932 Changed the way attribute sets are handled in the retrieval
933 module. These are now cached, just like the abstract syntaxes
936 Changed YAZ so that it links with compiled ASN.1.
938 Added Explain-schema definitions and mapping routines. The following
939 Explain categories have been implemented: AttributeDetails,
940 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
942 Fixed minor bug in Windows version of Server Library.
944 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
946 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
948 Added EXTERNAL: UNIverse Resource Report (non-standard).
950 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
951 ENUMERATED and SET OF.
953 * Added 'const' to some of the char pointer arguments for the
954 functions, data1_read_node, data1_getelementbytagname,
955 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
958 Fixed bug in data1_insert_taggeddata - the last_child member of
959 parent wasn't initialised.
961 * Changed data1_read_record and data1_read_node so that the supplied
962 "SGML"-buffer is read-only. In particular the resulting data1 - tree
963 doesn't refer to any parts of the "SGML"-buffer.
965 Fixed bug in server library (Windows version of statserv_remove).
967 * Changed code so that it compiles as C++. The type definition
968 of Odr_fun which is a member of Odr_arm was changed. The result is,
969 that an explicit typecast is needed for the fun pointer when
970 using Odr_arm - as in:
971 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
973 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
975 Implemented the new structured date and time definition as approved
976 by the ZIG. Added schemaId element to the specificTag in Espec-1
977 (also approved at the last ZIG). Thanks to RVDM.
979 Added some Object identifiers (RVDM).
981 Changed the Update Extended Service (RVDM).
983 Added command "refid" to client which specifies referenceId for
984 the following requests.
986 Implemented extended service handling for server. See ztest.c
987 for an example as well as backend.h. New handlers are registerd
990 * Changed interface for sort in server.
992 Added new members to statserv_options_block. It allows a server
993 to read options from another source than just the command line. Thanks
994 to Charles Woodfield.
996 * Changed definition of Z_Triple in file prt-grs.h - member boolean
997 renamed to zboolean. Some C++ compilers complained about the name.
999 Minor changes to gils.abs. Added index 's' (sort) on title
1000 and date/time-last-modified.
1002 --- 1.4pl2 1998/1/30
1004 Fixed bug in server library regarding inetd mode (-i). This bug
1005 was introduced by release 1.4.
1007 --- 1.4pl1 1998/1/29
1009 Added sort facility in client and backend server interface.
1011 Fixed problem with dependencies in Makefile(s).
1013 Fixed bugs for encoders/decoders of extended services and
1016 Implemented sub-tree feature for schemas. Sub-trees are
1017 referenced in *.abs-files. See explain.abs for an example
1018 of the use of this feature.
1020 Modified bib1.att; local attributes for ANY didn't include
1021 ANY itself (only affects use of the retrieval module).
1023 Fixed bug in plain SGML reader in function data1_read_node:
1024 tags with prefix "var" was incorrectly interpreted as variants.
1026 Added feature "sub-schemas" to enable references to - and definitions
1027 of - group of elements.
1029 * Removed member parent from type data1_element (in data1.h).
1031 Implemented function odr_nullval() that returns the value of
1034 * Removed member num_children from data1_node (in data1.h).
1036 Made NT service interface part of the server library. The
1037 function statserv_main uses the NT service when required and
1038 calls the statserv_start / statserv_close routines.
1040 Routine zget_SearchRequest and zget_PresentRequest fills
1041 resultSetName/Id member with "default" instead of "Default".
1043 Fixed memory leak in server. Request queue member wasn't freed.
1045 Fixed nmem_exit so that memory is freed.
1049 Revised the CCL parser utility to be thread safe.
1051 Added function, oid_ent_to_oid, to replace the function
1052 oid_getoidbyent, which is not thread safe.
1054 * Added nmem_init and nmem_exit to initialize and release
1055 NMEM resources. Function nmem_init should be called once in the
1056 initial thread before NMEM/ODR is used. statserv.c and client.c
1057 have been changed accordingly. The change was necessary to make
1058 NMEM thread safe. The NMEM memory pool is shared amongst threads
1059 in a process. Unix-based applications will still work fine without
1062 Added NT Services interface for the the Z39.50 (statserv) Server.
1063 Refer to the ztest.c source on the usage.
1065 Windows 95/NT port using MSVC5.0. Project files are included in the
1068 * Defined new 'global' handle for the retrieval (data1) system. The
1069 new handled, data1_handle, describes the state of the data1 system.
1070 This handle is passed as first argument to virtually all
1071 data1 related routines. The functions data1_create and data1_destroy
1072 creates and destroys a data1 handle respectively.
1074 Added ODR encode stream member to all backend request structures
1075 init, search, scan etc. This stream should be used to allocate all
1076 memory used for the response when thread safe operation is needed.
1078 Changed the comstack utility, cs_addstr, to be thread safe. The
1079 returned hostname string returned by the function is now part the
1082 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1083 function. The cs_straddr takes a COMSTACK handle as argument, so this
1084 function must be used after cs_create and before bind/connect.
1085 This function is thread safe.
1087 Moved test server to 'ztest' directory - generic server code still
1088 in 'server' directory.
1090 Made prefix query (pquery.c) utility thread safe.
1092 Added new function modifier YAZ_EXPORT to 'export' public DLL
1093 functions when using windows (see include/yconfig.h).
1095 Added definitions to the OID database (util/oid.c) (RVDM).
1097 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1099 Added call to ccl_rpn_delete in client program.
1101 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1102 release of RPN structure.
1104 Added support for C++, headers uses extern "C" for public definitions.
1105 With input from RVDM.
1107 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1108 Thanks to Ronald van der Meer (RVDM).
1110 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1112 Added support for private extensions to the OID database
1113 (oid_setprivateoids()). Thanks to RVDM.
1115 Added optional, physical ANY (key replication)
1117 Fixed null-reference problem in GRS-1 output filter.
1119 Proximity operator added to Prefix Query Format (PQF).
1121 In test client command "base" accepts multiple databases.
1123 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1127 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1129 Smallish bug-fixes in the new encoders/decoders (explain).
1131 Bug fixed in DeleteRequest.
1133 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1135 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1137 Added SOIF syntax (using private OID for now) to retrieval module and client.
1139 Added Update extended service.
1141 Added SearchResult-1 additional info structure.
1143 Added optional CCL (ISO8777) interpreter as separate module. Available
1146 --- 1.2 1996/6/10 (1st anniversary release)
1148 Added Summary record syntax. Lightly tested.
1150 Added OPAC record syntax. Untested.
1152 Added ResourceReport service encoders/decoders. Untested.
1154 Fixed bug in z_Unit - wrong tagging on unitSystem.
1156 Fixed bug in the DiagRecs decoder.
1158 Added options for max PDU size and session timeout to frontend-server.
1160 Added documentation of query-language parsers and other supporting utilities.
1162 [frontend-server] Added Attribute set to the bend_scanrequest API.
1164 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1165 surrogate diagnostics were generated.
1167 [retrieval] Allow multiple local values for attribute.
1169 [retrieval] Allow multiple attributes per element in .abs files. index type.
1171 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1173 --- 1.1pl2 1996/4/10
1175 Minor changes, mostly specific to Zebra's requirements (retrieval)
1179 Repaired bug in frontend server when running multiple listening
1180 endpoints in dynamic mode.
1182 z_External() now won't break if a known, ASN.1 value comes encapsulated
1183 in an octet-string. The value will pass through unmodified in an Odr_oct.
1185 Added a bit of code to the demo client to decode & display
1186 ASN.1-structured records represented in the octet-aligned branch of
1187 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1189 Added z_ext_getentbyref() to the ASN module. Doc updated.
1191 * Completed the SCAN definition in the ASN module. This may break SCAN
1192 code based on older YAZ-versions at compile-time. The fix is easy -
1195 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1196 under the SCAN definition. Remember to initialize this, server-people.
1198 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1199 that this does not extend to ODR and ASN.
1201 Comstack allows insertion of established socket (primarily for
1202 inetd-operation of servers). Doc updated.
1204 Front-end server can now start from the inetd in TCP mode. Doc
1207 --- 1.0pl4 1996/1/24
1211 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1212 the rank and record number.
1214 Adjustments to the frontend server.
1216 Fixed diagnostic BER dumper. It ignored the file argument.
1220 Various changes to retrieval module.
1222 Changed the union discriminators of the protocol files from enums to
1223 ints paired with #defines.
1225 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1228 *Changed operator in the RPN structure to 'roperator', again to avoid a
1231 Fixed problems in Explain decoders/encoders.
1233 --- 1.0pl2 1995/12/6
1235 Memory bug in log module fixed.
1237 --- 1.0pl1 1995/12/5
1239 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1241 Bug in Explain DatabaseInfo module fixed.
1243 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1247 The shift to v1.0 signals that we now consider the *core* functionality
1248 of YAZ reasonably stable (the core being more or less equivalent to
1249 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1250 tested (Explain not at all - though that will happen soonish).
1252 Minor changes to code to support Windows port.
1254 Various minor changes after we're getting to use GRS-1 & co. more.
1256 Added Espec-1 format.
1258 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1259 of the protocol and it cannot be selected when encoding (maps into 'string'
1260 when decoding). Needed to talk to some servers.
1262 Demo client can request simple element set names.
1264 Added Diagnostic Format encoders/decoders.
1266 Added simple Close handling to frontend server (no hooks for resource
1267 reporting yet), and demonstration client.
1269 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1271 --- 1.0b3 1995/08/24
1273 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1274 handled incorrectly when records were requested in the searchResponse. This
1275 will only affect you if you use the frontend-server.
1277 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1278 Test-client will ask for and print GRS1. Ztest will return dummy records
1281 Added Explain encoders/decoders to the service-level API. Untested.
1283 Added Extended Services: Item Order encoders and decoders to the Service-
1284 level API. Untested. We could use a recent copy of the pertinent bits
1285 of the ILL protocol to add those bits.
1287 Added diagnostic format 1 encoders/decoders to the service-level API.
1290 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1291 odr_cons.c, which causes a more correct output.
1293 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1294 was always set to 0 when no records were requested in the searchRequest.
1296 * Added better external-handling. This shouldn't harm old code that
1297 *encodes* externals. It can break code that looks for a
1298 'single-ASN1-type' representation, since those types that are known
1299 are now decoded immediately. Look at the SUTRS sample code in
1300 seshigh.c and client.c. Documentation updated.
1302 Handling of structured records in bend_fetchresponse. Length -1 marks
1303 structured record, type is deduced from format field.
1305 --- 1.0b2 1995/06/27
1306 Fairly quick maintenance release to add SUTRS support.
1308 Fixed handling of SUTRS records in the demonstration client.
1310 * Added format field to the bend_fetchrequest and bend_fetchresponce
1311 structures of the backend API (frontend server). When the record is
1312 returned, the value of the format field is mapped to an OID. The
1313 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1314 of the record. The special value VAL_NONE in the bend_request means
1315 that no specific format was requested by the client. Documentation
1316 updated accordingly. Test server (ztest) will return a fixed dummy
1317 SUTRS record if your client requests SUTRS.
1319 Documentation updated accordingly.
1321 You can now set external libraries and RANLIB support in the top-level
1325 First public release.
