1 Possible compatibility problems with earlier versions marked with '*'.
3 Handle user defined stylesheet for SRW/SRU.
5 --- 2.0.9-3 2004/01/06 Debian/Windows
7 Fix a bug with decoding of XML packed records.
9 --- 2.0.9-2 2004/01/05 Debian only
11 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
13 Fix bug in SRW/SRU diagnostics decoding.
17 Fixed bug in Generic Frontend Server which could drop records exceeding
18 preferred message size. Reported and fixed by Irina Dijour.
20 Fixed calculation of package size for structured records in Generic
21 Frontend Server. Reported and fixed by Irina Dijour.
23 Fixed namespace for SRW/SRU diagnostics.
25 Fixed SEGV in yaz-client that occured for HTTP connection errors.
29 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
30 this version is incompatible with version 1.0 and older YAZ SRW/SRU
33 CQL changes to reflect recent changes to the specification:
34 * Documentation talks about context sets instead of index sets.
35 * Documentation talks about indexes instead of qualifiers.
36 * The CQL-to-PQF transformer's configuration file now uses
37 "index.set.name = <attributes>" instead of the old form
38 "qualifier.set.name = <attributes>". (Both forms are still
39 understood but the latter is deprecated.)
40 * CQL terms with no explicit index specified are now interpreted as
41 cql.serverChoice instead of srw.serverChoice (which of course
42 behaves exactly the same.)
46 MARC conversion can now generate ISO2709 output in another
47 character set. yaz-marcdump uses this facility if you invoke it
50 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
51 functions from there can be used from C++.
55 Frontend server now transfers memory from decoded packages to stream
58 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
59 references to show up.
61 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
62 the ZOOM Abstract API. The older names for the same options are still
63 also supported for the benefit of old applications.
65 ZOOM-C supports "implementationId" and "implementationVersion" options
66 to go along with "implementationName". These allow the user code to
67 specify identification strings to be sent to servers.
68 Add OID for the new ExtLite attribute set.
70 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
71 as requested/supplid by Ere Maijala <ere@atp.fi>
73 For generic frontend server, reverse the order of
74 "toolkit-supplied / application-supplied" strings sent as implementationId,
75 Name and Version. Also, remove the spaces around the slash. This brings
76 the GFS in line with the behaviour of ZOOM-C on the client side.
78 Add function ZOOM_scanset_display_term.
80 yaz-client shows scan displayTerm if present.
82 Utility yaz-iconv is now installed by default along with the man page
85 Extend configure check for OpenSSL to use pkg-config where available (such
88 Incorporate patch by Morten Bogeskov which allows a Unix file socket
89 server to specify uid/gid/mask for socket using the format
90 unix:[user=uid,][group=gid,][umask=mask,]file=path
91 If file= is omitted the existing format is assumed, e.g.
93 in which case the mask is 0666 (rw for everybody).
95 Major restructure of YAZ source. All source in libyaz is in src directory.
96 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
97 util (utility programs such as ASN.1 compiler, yaz-marcdump).
99 Added man page for utility yaz-marcdump (used to be called marcdump).
100 yaz-marcdump is installed by 'make install'.
102 Fixed a memory leak in Generic Frontend Server that occurred when decoding
103 of incoming package failed.
105 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
107 Change prototype of odr_perror: add const to message string.
109 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
111 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
112 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
113 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
114 DNS lookup. There should not be any compatibility problems with this
115 assuming that blocking=1 or 0 is used.
117 Fix bad reference in UNIX comstack in function cs_addrstr.
119 Fix for compilation on AIX.
121 The generic front-end server (server/seshigh.c) now supports returning
122 Init diagnostics to the client in User-information-field, in
123 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
128 Allow any CQL relation (not just all,any,exact,scr).
130 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
131 that features the same UI.
133 Implemented command update0 in YAZ client which is equivalent to
134 update but uses old of Ext Update ASN.1.
136 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
137 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
138 Previously no OID was used for this info.
140 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
141 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
142 returns 'malformed search term' otherwise.
144 SortResponse member resultCount now set to NULL in sort handler of
147 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
150 Add three new utility functions for translating OIDs between various
151 formats -- symbolic name such as "Usmarc", minus-1-terminated int
152 arrays and dotted strings such as "1.2.840.10003.9.5.1":
153 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
154 char *oid_to_dotstring(const int *oid, char *oidbuf);
155 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
157 Reverted modifications for ES Update definition for z_IU0Update
158 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
159 is back to YAZ 2.0.2.
161 String value attributes for CCL parser.
163 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
164 which their FirstSearch server returns in Init responses, sometimes
165 carrying useful diagnostic information when Init fails. This has the
166 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
167 "z39.50/oclcui.asn", where its definition is somewhat different from
168 what OCLC document on their web-site, as required to interoperate with
171 Support for anonymous authentication in yaz-client. Use the command
174 * Fix the OID of the Index Data-local "admin" Extended Service from
175 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
176 the 1000, which indicates a locally-defined OID, was a mistake.
180 Fix CCL directive @case handling so that it affects string match for
181 both CCL keywords and qualifiers.
183 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
184 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
185 Decoder has been updated with ASN.1 changes as listed in
186 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
187 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
188 z_IUUpdate, remains unchanged.
190 ZOOM_record_get may now return a record in a specific character set.
191 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
192 "from" is the character set of record as returned by target. "to" is
193 the character set to be returned. If omitted, "to" is UTF-8.
195 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
197 New ODR utility, odr_getelement, which returns name of element for
198 which encoding/decoding failed.
200 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
201 in cases where a required element was omitted.
203 Bug fix: some MARC8 sequences were not converted.
205 New ZOOM option "step" which specifies number of records to be
206 retrieved in one chunk. Used in conjunction with "start" and "count".
208 SRW support for yaz-client. Use scheme http: to use it, e.g.
211 yaz-client no longer does (un)intelligent character set conversions
212 by default. Can be enabled with charset and marc_charset commands.
214 xmalloc trace fix for 64-bit systems such as DEC alpha.
216 Solaris 2.6 compile fix.
218 New function, cql_strerror() translates SRW error codes, as returned
219 by cql_transform_error(), into human-readable English strings. Used
220 in yaz-client diagnostics when appropriate.
222 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
223 converts it into a type-1 query which is sent to the server. This
224 makes CQL available for use with all Z-servers, as opposed to the tiny
225 minority that can handle CQL queries themselves.
229 New Debian package layout similar to the Redhat Package layout.
231 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
232 and search result respectively.
236 Redhat package is now several packages: libyaz (runtime libraries),
237 libyaz-devel (development and documentation, and yaz (utility programs).
238 Package spec file by Morten Bøgeskov.
240 New member 'schema' in struct bend_fetch_rr which the name of requested
241 schema (SRW/SRU) for record (or NULL if none was given). The fetch
242 handler MAY set this to reflect the schema of the returned record.
244 New member 'display_term' in struct scan_entry. GFS now sets member entries
245 and allocates scan entries to be filled by user scan handler. In previous
246 version, entries member was allocated by the scan handler. That still works,
247 but the GFS will ignore member display_term - assuming it was NOT set by
248 the handler. The fact that the GFS now allocates the entries both allows
249 for new members and makes a scan handler easier to write.
251 Fix CQL lex buffer overflow.
253 SRW/SRU recordPacking. For SRW default recordPacking is string. For
254 SRU default recordPacking is string.
256 SRU protocol support for frontend server.
258 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
260 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
262 Added scan for the ZOOM shell (zoomsh).
266 * String Identifers for Schemas (Amendment 5).
267 http://lcweb.loc.gov/z3950/agency/amend/am5.html
268 Old definition for schema
269 Odr_oid *schema; /* OPT */
274 Z_InternationalString *uri;
275 #define Z_Schema_oid 1
276 #define Z_Schema_uri 2
279 * resultCount parameter to Sort Response (Amendment 1).
280 http://lcweb.loc.gov/z3950/agency/amend/am1.html
282 Support for SRW 1.0 over HTTP. This is an optional feature and
283 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
286 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
287 on the same port. SRW SearchRetrieveRequests are mapped
288 to bend_init,bend_search,bend_fetch,bend_close.
290 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
292 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
293 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
295 ZOOM connections are SRW based if schem http is used for hostname
296 in connect, e.g. z = ZOOM_connection_new("http://myserver");
297 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
299 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
300 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
301 distance=n, order=true/false, relation=le, prox unit=word. If
302 n is omitted, distance 1 is used.
304 Fixed problem with C compiler include path in wrong order.
306 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
307 on Solaris. Patch from Ko van der Sloot.
309 New MARC decode API. All new functions operate on a yaz_marc_t
310 handle. The most important new functions are: yaz_marc_create,
311 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
312 decode and destroy respectively. Decoder can produce formats
313 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
314 include/yaz/marcdisp.h.
316 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
317 to UTF-8, UCS-32, wchar_t or Latin-1.
319 * Prototypes for yaz_iconv_-functions moved to separate header
320 include/yaz/yaz-iconv.h.
322 Make a few private functions 'static' in unix.c. This prevents
323 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
325 For ZOOM connection, the options targetImplementation{Id,Name,Version}
326 are set when Init Response is received.
328 New function ZOOM_connection_error_x similar to ZOOM_connection_error
329 but returns diagnostic set as well.
331 New function yaz_strerror which is a portable wrapper for
332 strerror/strerror_r/GetLastMessage.
334 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
335 is returned for MARC. If type is "oai", then OAI MARC is returned.
337 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
342 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
344 Fix bad race conditions on SIGTERM and terminate gracefully in
347 Move retrieval (data1) module to Zebra since nobody seems to be
350 Add GRS-1 render for ZOOM using same format as yaz-client.
354 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
356 Fix broken ESpec handling in data1 module.
358 SGML reader parses comments and makes them part of the data1 tree.
360 Added several type casts so that YAZ compiles as C++ code.
362 ZOOM didn't handle PDU encoding failures properly.
364 Added more Bib-1 diagnostics (approved extensions).
366 GNU configure: better check for iconv.
368 More portable use of accept, getpeername. Check for socklen_t. Use
369 int/size_t if socklen_t is not defined.
373 PQF parser rejects bad queries - including those with extra
374 characters in them. PQF parser used to silently ignore that.
375 Cleaner API for PQF added, which allows you to get detailed
376 error information for bad queries (see yaz/pquery.h).
378 Fixed bug in ZOOM_record_get for type "database".
380 Implemented mini iconv library supporting conversions between
381 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
383 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
387 Fixed ZOOM C record cache so that preferredRecordSyntax and
388 elementSetName is used to check for already fetched records.
392 Added three members in bend_initrequest structure to facilitate
393 character set negotiation.
395 Fixed a bug in frontend server that could cause indefinite
396 loops under rare conditions.
398 Revised character set utilities (charneg.h) so that encoding
399 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
401 For PQF, directive @term <type> sets term type for Scan/Search.
402 Here <type> is general, string, numeric, null. The term type
403 is inherited - just like @attr.
405 New call odr_set_charset that sets character set conversion for
406 international-strings on a ODR stream. Prototype is:
407 int odr_set_charset(ODR o, const char *to, const char *from);
408 The InternationalString is still represented as C string in YAZ
409 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
410 won't). On the protocol level, you can use any encoding.
412 Support for UNIX sockets in ZOOM.
414 Solaris recv sometimes returns errno == ENOENT. It is treated as
415 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
417 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
418 both client and server. Code by Morten Bøgeskov.
422 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
423 that they can be used directly from Visual Basic. You must recompile
424 your windows APP if you're using ZOOM.
426 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
427 Commands "lang" and "charset" sets language and character set respectively.
428 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
429 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
431 Attributes from multiple CCL fields may be OR'ed rather than merged
432 using directive "@field or". Fields are still merged by default -
433 equivalent to "@field merge".
435 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
438 Fixed bug in zget for parameter ExtendedServicesResponse.
444 Added PQF feature: '@attr type=value' may be written as '@type=value'.
446 Client displays USR.1:SearchResult-1 (hits per term).
448 Additional Search Info for search in Generic Frontend Server.
450 Fixed CCL parsing of "field=s".
452 WIN32 installer - using the excellent NSIS software from nullsoft.
454 Fixed CCL parsing of "field = - <number>".
456 Added function yaz_marc_decode that decodes MARC for line mode
457 display or XML (similar to that used by JZKit).
459 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
460 Z39.50. But ISO/ILL was, however.
462 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
463 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
465 http://lcweb.loc.gov/z3950/agency/amend/am2.html
466 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
470 New YAZ client features: Command completion and new commands:
471 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
472 Code provided by Jacob Poulsen.
474 New call oid_trav, that visits all registered OIDs via callback.
476 Function ZOOM_record_get now returns const char pointer rather than
477 void pointer. It saves a lot of type casts.
479 For YAZ client, command "auth" now allows you to set authentication
480 in IdPass style. It is enabled when three tokens are given - order
481 is user, group and password.
483 Fix memory leaks in MARC record handling for ZOOM.
485 New option for YAZ client, -k <kilobytes> that sets
486 maximum record size. Similar to -k option for generic frontend
487 server and yaz-ztest.
489 More fixes for scan. Non-zero stepSize handled. OID's fixes.
491 Prefix query parser reports "fail" when bad attribute set is given.
493 Fix in MARC decoder. Proximity logging. Fix for attribute set
494 in scan handler for server. Patches by Shigeru Ishida.
496 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
499 Configure option --with-openssl=<dir> now works when a directory is
500 specified. Patch provided by Morten Bøgeskov.
502 New option for YAZ client, -u <auth>, that sets authentication.
504 ZOOM fix: error information was sometimes "missing", since error
505 was cleared/reset too when it shouldn't.
507 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
511 Scan for ZOOM API. New object ZOOM_scanset. New functions
512 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
513 ZOOM_scanset_destroy.
515 New ZOOM function, ZOOM_connection_last_event, that returns type
516 of last event (such as "receive data", "send data", "apdu received",
519 New ZOOM option, schema, that specifies schema for retrieval.
521 New CCL feature. Qualifiers can be aliases for one or more
522 other qualifiers (if more than one is given, OR is used).
524 ZOOM uses named result sets if target supports it.
526 Two new YAZ client commands: . (dot, which sources a script of YAZ
527 client commands), and ! (to execute shell command.). Implemented
530 Working on Debian packages.
534 YAZ client enables named result sets only if target supports it.
536 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
538 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
539 with key="host" to get same result.
541 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
542 Function Z3950_resultset_record(s) returns references to records
543 "owned" by resultset. To become owner use Z3950_record_clone.
545 Function z_ext_record handles Extended Services. Thanks to
550 CCL Parser fix: ignore token comma when dealing with and-lists.
552 Documentation updates for COMSTACK.
554 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
555 Changed prototype Z3950_records. For some functions, int parameters
556 were changed to size_t.
558 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
561 New MARC decode/display function, marc_display_exl, which properly rejects
562 non-ISO2709 records. YAZ client uses it.
566 Fix bug: local attribute set wasn't set correctly in PQF strings.
570 * Old Z39.50 codecs no longer supported.
572 Added ZOOM C binding. See http://zoom.z3950.org/
574 Renamed states for COMSTACKs to avoid confusion with events.
576 Implemented cs_look and proper cs_rcvconnect.
578 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
580 Configure detects POSIX threads on OpenBSD.
582 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
583 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
585 When error is returned from present handler, non-surrogate diagnostic
586 is returned in present response (and fetch handler is no longer called).
588 * Minor adjustments to pquery parser (PQF). Token characters may be
589 escaped by using backslash (C-style).
591 PQF parser allows string attribute values to be specified. For @attr,
592 non-numeric characters after the equal-sign are treated as strings
593 (e.g. @attr 9=title).
595 CCL trunction character may be defined (@truncation in file)
597 * function zget_ExtendedServicesRequest sets waitAction to
598 waitIfPossible (was wait).
600 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
603 CCL operator names may be set in field definition files (CCL_bibset).
604 See ccl/bib1 for an example.
606 Fixes in ASN.1 compiler for C++ compatibility.
608 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
609 and "op_or" to avoid conflict with C++.
611 Fixed problem with GNU readline detection on Redhat 7.0.
613 Added step-size for Scan backend handler.
615 Fixed bug that made the frontend server crash when no attribute
616 set was specified for scan.
618 Front-end server automatically switches to original working directory
619 when installed as an NT service. Previously -w had to be specified to
622 Added extended attributes for retrieval module (data1), so that data1
623 records carry d1_readXML/SGML attributes. d1_read also supports
624 null-data rules ( <tag/>)
626 On UNIX when POSIX threads are available, a separate library libyazthread
627 is created. Programmers should link with that library and the yaz library
628 when using threads. The reason for the split was that some applications
629 on Linux, such as Apache, doesn't work well when using shared objects that
632 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
633 (or any frontend server) in SSL mode by specifying ssl: followed by
634 address. Only tested on UNIX.
636 Added feature for CCL module. Virtual structure s=al or s=ol generates
637 and-list and or-list respectively instead of phrase search.
641 * Added prefix "yaz_" for the functions log_init.., log_file.. and
642 log_mask_str. This was done to avoid name conflicts with other libraries
643 (such as other PHP extensions).
645 Added raw OID member for preferred record syntax (request_format_raw)
646 and returned record syntax (output_format_raw) for backend fetch method.
648 Config file yaz-config now accepts options so that it returns specific
649 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
651 Shared library support for UNIX using GNU libtool.
653 * Modified backend interface. Request/Response struct's replaced by
654 one read/write C struct. For example bend_fetchrequest and
655 bend_fetchresult have been replaced by single bend_fetch_rr struct.
656 Every handler - even search has to be registered in bend_init
657 handler. This means that the YAZ library no longer refers to
658 external functions and it makes it possible to make the whole
659 thing a single DLL/SO.
661 Added Segment handler for backend server.
663 Added Zmbol/Zebra administrative functions to YAZ client.
665 Threaded frontend server on UNIX (when POSIX Threads are available).
666 Starting the server with option -T enables multi-threading.
670 Added configure option --enable-comp/disable-comp to control use
671 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
672 located in sub directory asn.
674 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
675 in ${exec_prefix}/bin along with the other programs yaz-client and
678 GNU automake used to maintain makefiles.
682 Changed retrieval module so that we can load records with no abstract
683 syntax defined. Tagpaths in these records are fully composed of string
686 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
690 On UNIX, the generated makefile now supports a proper 'make install'.
691 The prefix can be set via GNU configure to set the install location
692 (default is /usr/local).
694 * YAZ programs client and ztest were renamed to yaz-client and
695 yaz-ztest to avoid conflicts when users install YAZ in "standard"
696 locations, such as /usr/bin,/usr/local/bin,etc.
698 * YAZ Header files were moved from include to include/yaz. YAZ Header
699 files are referred to as include <yaz/log.h> rather than <log.h>.
700 The YAZ include path (-I ..) is therefore the same as before. Programmers
701 should update their #include statements or use -Ipath/include/yaz
702 instead. The main motivation for doing this change is that YAZ header files
703 can be installed in "standard" locations /usr/include,/usr/local/include
704 without introducing conflicts, since ALL YAZ header files are stored
705 in subdirectory yaz (under /usr/include for example).
707 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
708 rather than project/workspace files. We switched because project files
709 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
712 Changed name of logging function, logf, to yaz_log, to prevent name
713 clash with some math-log functions. The YAZ header log.h defines logf
714 to yaz_log (#define) so there should be no incompatibilities by this
717 Added bend_start/bend_stop handlers for server. These handler are
718 called on start/stop of server. For windows they are called whenever
719 a service is started/stopped.
721 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
722 a fairly small ASN.1 compiler written in Tcl. The compiler is located
723 in util/yc.tcl. The auto-generated C code structures are, in a few
724 cases, incompatible with the old decoders. There are differences in the
725 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
726 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
727 The preprocessor variable ASN_COMPILED is defined when the compiled
728 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
729 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
730 wish to use the old encoders/decoders you can specify --disable-yc
733 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
734 version so that it supports both new - and old version of DB Update
736 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
737 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
738 change. The name parameter can be set to 0 in which no name is specified
739 for the construction. The macros odr_implicit and odr_explicit sets name
740 parameter to zero for the construction involved. New macros
741 odr_implicit_tag and odr_explicit_tag are similar to the others,
742 except that a name parameter is added. For programmers' that don't use
743 ODR they probably only need to change the call to z_APDU and z_External.
745 Added access control facility by interfacing the TCP wrapper library.
746 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
747 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
748 name of the daemon and enables the access control as specified in
749 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
751 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
752 den Dool <H.M.vdnDool@kub.nl>.
754 Added reference ID parameter to most functions in server API - refer
755 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
757 Changed name of ccl library to libccl.a (was ccl.a).
759 Fixed bug in decoder for Explain (Category TargetInfo).
761 Added support for GNU readline in client. Thanks to Jacob Poulsen
762 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
764 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
765 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
766 IMPLEMENTATION! This change was made to the development version before
767 the ZIG decided to retract the amendment. If any users MUST be
768 compatible with the original Update definition, PLEASE CONTACT US, and
769 we will include a separate definition corresponding to the old Update
770 ES. Note that because of the change to the ASN.1 of the
771 TaskPackageRecordStructure we cannot define a single structure that
772 will support both versions.
774 * Added const modifier to buffer parameter for some ODR/BER encoding
775 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
776 completeWAIS, odr_dumpBER.
778 Fixed bug in client.c which caused a crash when a scanResponse didn't
779 contain positionOfTerm.
781 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
782 * will cause an error in a client if a non-YAZ target sends both a
783 * list of Scan entries and non-surrogate diagnostics.
785 Retrieval module enhancements. Tag sets may be typed in the reference
786 to it. From the .abs-file the "tagset" directive takes a third optional
787 integer type for the tag set referenced. From a .tag-file the "include"
788 directive takes a third optional type as well. The old "type" directive
789 in the tag set itself is still recognized but acts as the default type
792 Backend interface change. Individual Scan terms returned from bend_scan
793 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
794 in include/backend.h.
796 Retrieval module enhancements. Multiple tag sets and attribute sets may
797 be specified in abstract syntax specs. Revised the error/warning for
798 logging messages reported by the retrieval module when reading the
801 Object Identifier system (oid_..) changed. The API is backwards
802 compatible but the oid-routines now allocates new OID's when needed.
803 Raw OID's may be specified in oid_getvalbyname.
805 YAZ now uses GNU configure to generate Makefile(s).
807 * Minor changes in some of the member names of DeleteResultSetRequest and
808 DeleteResultSetResponse. See include/proto.h.
810 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
811 and added member 'languages' in TargetInfo (which was missing).
813 Changed the way attribute sets are handled in the retrieval
814 module. These are now cached, just like the abstract syntaxes
817 Changed YAZ so that it links with compiled ASN.1.
819 Added Explain-schema definitions and mapping routines. The following
820 Explain categories have been implemented: AttributeDetails,
821 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
823 Fixed minor bug in Windows version of Server Library.
825 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
827 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
829 Added EXTERNAL: UNIverse Resource Report (non-standard).
831 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
832 ENUMERATED and SET OF.
834 * Added 'const' to some of the char pointer arguments for the
835 functions, data1_read_node, data1_getelementbytagname,
836 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
839 Fixed bug in data1_insert_taggeddata - the last_child member of
840 parent wasn't initialised.
842 * Changed data1_read_record and data1_read_node so that the supplied
843 "SGML"-buffer is read-only. In particular the resulting data1 - tree
844 doesn't refer to any parts of the "SGML"-buffer.
846 Fixed bug in server library (Windows version of statserv_remove).
848 * Changed code so that it compiles as C++. The type definition
849 of Odr_fun which is a member of Odr_arm was changed. The result is,
850 that an explicit typecast is needed for the fun pointer when
851 using Odr_arm - as in:
852 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
854 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
856 Implemented the new structured date and time definition as approved
857 by the ZIG. Added schemaId element to the specificTag in Espec-1
858 (also approved at the last ZIG). Thanks to RVDM.
860 Added some Object identifiers (RVDM).
862 Changed the Update Extended Service (RVDM).
864 Added command "refid" to client which specifies referenceId for
865 the following requests.
867 Implemented extended service handling for server. See ztest.c
868 for an example as well as backend.h. New handlers are registerd
871 * Changed interface for sort in server.
873 Added new members to statserv_options_block. It allows a server
874 to read options from another source than just the command line. Thanks
875 to Charles Woodfield.
877 * Changed definition of Z_Triple in file prt-grs.h - member boolean
878 renamed to zboolean. Some C++ compilers complained about the name.
880 Minor changes to gils.abs. Added index 's' (sort) on title
881 and date/time-last-modified.
885 Fixed bug in server library regarding inetd mode (-i). This bug
886 was introduced by release 1.4.
890 Added sort facility in client and backend server interface.
892 Fixed problem with dependencies in Makefile(s).
894 Fixed bugs for encoders/decoders of extended services and
897 Implemented sub-tree feature for schemas. Sub-trees are
898 referenced in *.abs-files. See explain.abs for an example
899 of the use of this feature.
901 Modified bib1.att; local attributes for ANY didn't include
902 ANY itself (only affects use of the retrieval module).
904 Fixed bug in plain SGML reader in function data1_read_node:
905 tags with prefix "var" was incorrectly interpreted as variants.
907 Added feature "sub-schemas" to enable references to - and definitions
908 of - group of elements.
910 * Removed member parent from type data1_element (in data1.h).
912 Implemented function odr_nullval() that returns the value of
915 * Removed member num_children from data1_node (in data1.h).
917 Made NT service interface part of the server library. The
918 function statserv_main uses the NT service when required and
919 calls the statserv_start / statserv_close routines.
921 Routine zget_SearchRequest and zget_PresentRequest fills
922 resultSetName/Id member with "default" instead of "Default".
924 Fixed memory leak in server. Request queue member wasn't freed.
926 Fixed nmem_exit so that memory is freed.
930 Revised the CCL parser utility to be thread safe.
932 Added function, oid_ent_to_oid, to replace the function
933 oid_getoidbyent, which is not thread safe.
935 * Added nmem_init and nmem_exit to initialize and release
936 NMEM resources. Function nmem_init should be called once in the
937 initial thread before NMEM/ODR is used. statserv.c and client.c
938 have been changed accordingly. The change was necessary to make
939 NMEM thread safe. The NMEM memory pool is shared amongst threads
940 in a process. Unix-based applications will still work fine without
943 Added NT Services interface for the the Z39.50 (statserv) Server.
944 Refer to the ztest.c source on the usage.
946 Windows 95/NT port using MSVC5.0. Project files are included in the
949 * Defined new 'global' handle for the retrieval (data1) system. The
950 new handled, data1_handle, describes the state of the data1 system.
951 This handle is passed as first argument to virtually all
952 data1 related routines. The functions data1_create and data1_destroy
953 creates and destroys a data1 handle respectively.
955 Added ODR encode stream member to all backend request structures
956 init, search, scan etc. This stream should be used to allocate all
957 memory used for the response when thread safe operation is needed.
959 Changed the comstack utility, cs_addstr, to be thread safe. The
960 returned hostname string returned by the function is now part the
963 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
964 function. The cs_straddr takes a COMSTACK handle as argument, so this
965 function must be used after cs_create and before bind/connect.
966 This function is thread safe.
968 Moved test server to 'ztest' directory - generic server code still
969 in 'server' directory.
971 Made prefix query (pquery.c) utility thread safe.
973 Added new function modifier YAZ_EXPORT to 'export' public DLL
974 functions when using windows (see include/yconfig.h).
976 Added definitions to the OID database (util/oid.c) (RVDM).
978 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
980 Added call to ccl_rpn_delete in client program.
982 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
983 release of RPN structure.
985 Added support for C++, headers uses extern "C" for public definitions.
986 With input from RVDM.
988 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
989 Thanks to Ronald van der Meer (RVDM).
991 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
993 Added support for private extensions to the OID database
994 (oid_setprivateoids()). Thanks to RVDM.
996 Added optional, physical ANY (key replication)
998 Fixed null-reference problem in GRS-1 output filter.
1000 Proximity operator added to Prefix Query Format (PQF).
1002 In test client command "base" accepts multiple databases.
1004 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1008 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1010 Smallish bug-fixes in the new encoders/decoders (explain).
1012 Bug fixed in DeleteRequest.
1014 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1016 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1018 Added SOIF syntax (using private OID for now) to retrieval module and client.
1020 Added Update extended service.
1022 Added SearchResult-1 additional info structure.
1024 Added optional CCL (ISO8777) interpreter as separate module. Available
1027 --- 1.2 1996/6/10 (1st anniversary release)
1029 Added Summary record syntax. Lightly tested.
1031 Added OPAC record syntax. Untested.
1033 Added ResourceReport service encoders/decoders. Untested.
1035 Fixed bug in z_Unit - wrong tagging on unitSystem.
1037 Fixed bug in the DiagRecs decoder.
1039 Added options for max PDU size and session timeout to frontend-server.
1041 Added documentation of query-language parsers and other supporting utilities.
1043 [frontend-server] Added Attribute set to the bend_scanrequest API.
1045 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1046 surrogate diagnostics were generated.
1048 [retrieval] Allow multiple local values for attribute.
1050 [retrieval] Allow multiple attributes per element in .abs files. index type.
1052 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1054 --- 1.1pl2 1996/4/10
1056 Minor changes, mostly specific to Zebra's requirements (retrieval)
1060 Repaired bug in frontend server when running multiple listening
1061 endpoints in dynamic mode.
1063 z_External() now won't break if a known, ASN.1 value comes encapsulated
1064 in an octet-string. The value will pass through unmodified in an Odr_oct.
1066 Added a bit of code to the demo client to decode & display
1067 ASN.1-structured records represented in the octet-aligned branch of
1068 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1070 Added z_ext_getentbyref() to the ASN module. Doc updated.
1072 * Completed the SCAN definition in the ASN module. This may break SCAN
1073 code based on older YAZ-versions at compile-time. The fix is easy -
1076 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1077 under the SCAN definition. Remember to initialize this, server-people.
1079 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1080 that this does not extend to ODR and ASN.
1082 Comstack allows insertion of established socket (primarily for
1083 inetd-operation of servers). Doc updated.
1085 Front-end server can now start from the inetd in TCP mode. Doc
1088 --- 1.0pl4 1996/1/24
1092 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1093 the rank and record number.
1095 Adjustments to the frontend server.
1097 Fixed diagnostic BER dumper. It ignored the file argument.
1101 Various changes to retrieval module.
1103 Changed the union discriminators of the protocol files from enums to
1104 ints paired with #defines.
1106 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1109 *Changed operator in the RPN structure to 'roperator', again to avoid a
1112 Fixed problems in Explain decoders/encoders.
1114 --- 1.0pl2 1995/12/6
1116 Memory bug in log module fixed.
1118 --- 1.0pl1 1995/12/5
1120 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1122 Bug in Explain DatabaseInfo module fixed.
1124 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1128 The shift to v1.0 signals that we now consider the *core* functionality
1129 of YAZ reasonably stable (the core being more or less equivalent to
1130 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1131 tested (Explain not at all - though that will happen soonish).
1133 Minor changes to code to support Windows port.
1135 Various minor changes after we're getting to use GRS-1 & co. more.
1137 Added Espec-1 format.
1139 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1140 of the protocol and it cannot be selected when encoding (maps into 'string'
1141 when decoding). Needed to talk to some servers.
1143 Demo client can request simple element set names.
1145 Added Diagnostic Format encoders/decoders.
1147 Added simple Close handling to frontend server (no hooks for resource
1148 reporting yet), and demonstration client.
1150 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1152 --- 1.0b3 1995/08/24
1154 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1155 handled incorrectly when records were requested in the searchResponse. This
1156 will only affect you if you use the frontend-server.
1158 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1159 Test-client will ask for and print GRS1. Ztest will return dummy records
1162 Added Explain encoders/decoders to the service-level API. Untested.
1164 Added Extended Services: Item Order encoders and decoders to the Service-
1165 level API. Untested. We could use a recent copy of the pertinent bits
1166 of the ILL protocol to add those bits.
1168 Added diagnostic format 1 encoders/decoders to the service-level API.
1171 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1172 odr_cons.c, which causes a more correct output.
1174 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1175 was always set to 0 when no records were requested in the searchRequest.
1177 * Added better external-handling. This shouldn't harm old code that
1178 *encodes* externals. It can break code that looks for a
1179 'single-ASN1-type' representation, since those types that are known
1180 are now decoded immediately. Look at the SUTRS sample code in
1181 seshigh.c and client.c. Documentation updated.
1183 Handling of structured records in bend_fetchresponse. Length -1 marks
1184 structured record, type is deduced from format field.
1186 --- 1.0b2 1995/06/27
1187 Fairly quick maintenance release to add SUTRS support.
1189 Fixed handling of SUTRS records in the demonstration client.
1191 * Added format field to the bend_fetchrequest and bend_fetchresponce
1192 structures of the backend API (frontend server). When the record is
1193 returned, the value of the format field is mapped to an OID. The
1194 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1195 of the record. The special value VAL_NONE in the bend_request means
1196 that no specific format was requested by the client. Documentation
1197 updated accordingly. Test server (ztest) will return a fixed dummy
1198 SUTRS record if your client requests SUTRS.
1200 Documentation updated accordingly.
1202 You can now set external libraries and RANLIB support in the top-level
1206 First public release.
