1 Added Authentication support to Generic Frontend Server in SRU
2 mode. Authentication using HTTP Basic is supported, as is the use
3 of 'x-username' and 'x-password' parameters in the request itself.
5 Added support for a new character set MARC8s identical to MARC8 except
6 that it converts combined characters to single Unicode characters in the
7 Latin-1 range (when possible).
11 ASN.1 compiler 0.4: generates brief Doxygen file header for
12 generated .h/.c files.
14 Utility yaz_iconv now supports conversion to MARC-8.
16 New facilities for the MARC module. The reading - and writing of
17 content are separate methods for the yaz_marc_t handle. The following
18 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
19 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
20 format). Write functions have prefix yaz_marc_write_.. The existing
21 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
22 available. Removed support for OAI-MARC and simplexml (not the
25 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
26 to be returned for this connection.
30 Allow multiple languages and charsets to be specified with
31 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
32 negcharset iso-8859-1,utf-8
34 Translation of proximity nodes from CQL into PQF now works.
36 Moved to automake 1.8, 1.9.
38 Added function yaz_log_set_handler which allows a log handler to be
39 installed. This handler will be called for all log messages. Output
40 to file is also produced; but that can be disabled by passing NULL
41 fname to yaz_log_init_file.
43 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
45 For SRW (including GFS), accept application/soap+xml as content-type
48 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
49 produces NO stylesheet reference even if a default stylesheet is specified
54 Updated Windows package to include yazd.dll + yazd.lib for the
55 Development component.
57 If the environment variable YAZ_LOG is set, then it is used as a
58 string indicating the default level of logging to use if not
59 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
60 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
61 used as before. So, for example, to omit warnings from YAZ logging,
64 cql_transform() now map structure and other attributes before indexes,
65 so that index-specific structures and other attributes can override
66 defaults. So now a combination of mapping specifications such as:
68 index.dc.date = 1=date-modified 4=5
71 cql_transform() now also respects the "always" mapping specification,
72 which establishes an initial set of attributes to be used for all
73 terms except where overridden by more specific attributes associated
74 with the index, relation or modifier.
76 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
77 which mode to use; one of "post", "get" or "soap" (SRW, default).
79 Fixes for yaz_iconv routines: changed trie-based character set conversions
80 to use only non-negative values for bit fields due to Sun's C compiler not
81 supporting negative values.
83 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
84 sequences where not read correctly. Fix by Rustam Usmanov.
86 Updated win/makefile to use options, settings which makes things
87 compile with VS C 2005.
91 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
93 In ZOOM socket code, use select instead of poll on MacOSX.
95 ZOOM-C now support client-side compilation of CQL into RPN that is
96 sent to the server, enabling CQL to be used against all Z39.50
97 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
98 ZOOM_query object, and submit it using ZOOM_connection_search().
99 The CQL-to-RPN translation uses a configuration file, the name of
100 which must be specified in the Connection's "cqlfile" option.
102 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
103 function, which takes as its start-term parameter a ZOOM_query object
104 (which may have had either CQL or RPN set into it).
107 --- 2.1.10 2005/11/29
109 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
110 GFS to support this as well. Backend handler, bend_srw_update, does the
111 update work. Code contributed by Ko van der Sloot.
113 Allow retrieval of Search Result-1 information in ZOOM by the use of
114 options that are attached to a result set. ZOOM documentation updated
117 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
118 UTF-8 conversion. Patch by Raj Patel.
120 Added option -m to GFS to control formatting of timestamps in log file.
122 Added 'exit' as synonym for 'quit' in yaz-client
124 Added support for specifying SRW resultSetId + resultSetIdleTime in a
125 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
126 for the new members. Patch by Ko van der Sloot.
128 Added support for SRU POST. It is supported for content-type
129 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
131 Do not build the separate Multi-threaded (MT) library libyazthread.la.
132 Instead make the library libyaz.la multi-threaded. Threading as a whole
133 can still be disabled by configure option --disable-threads. Previosly,
134 with older GLIBCs there were problems with MT libs under Apache. This
135 has now been fixed a long time ago.
137 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
140 CQL module modified to be case insensitive for relations/indexes/operations.
142 Fixed bug in CQL transform code: incorrect value relationModifieder
145 Added 'show all' command for yaz-client which retrieves all results
148 Added new yaz-client, xmles, which takes a (private) OID and
149 a document to be sent as an extended service request.
151 Describe new yaz-client commands wait_response and set_auto_wait.
153 Increase TCP/IP listener backlog from 3 (which I am guessing was
154 copied from the SunOS manual entry way back when) so SOMAXCONN, so
155 that the socket will queue as many incoming connections as it's able
156 to handle ongoing connections. In other words, it will never now
157 refuse a connection that it would be able to handle merely because
158 it's not got around to accepting() enough of the pending connections
159 yet. This is the behaviour anyway under Linux, where the listen()
160 argument is ignored; but not under BSD and on systems such as
161 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
162 YAZ-based servers should now be uniform across operating systems in
165 yaz-marcdump uses 64-bit file access on some systems. This is enabled
166 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
167 This allows yaz-marcdump to read large MARC batches (>2 GB).
169 Modified all YAZ source files - except the source which is auto-generated
170 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
173 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
174 corresponding to the existing *_setl() function. These allow option
175 values containing arbitrary valuues.
177 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
178 ZOOM_resultset_sort() in new applications. Its behaviour is identical
179 except that it returns an indicator of whether or not the sort
180 criterion was accepted (0 for OK, -1 for invalid).
184 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
185 MARC output rather than returning "new" buffer.
187 yaz-client warns about unknown init options.
189 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
193 Added support for SRW sort in Generic Frontend Server. Patch
194 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
195 sortKeys - or NULL if none is provided.
197 Fixed bug #307: It was impossible to specify indefinite/no timeout
198 for ZOOM_event. Special timeout value -1 now means indefinite timeout
201 Added support for multiple languages and charsets to be specified in
202 ZOOM. Each charset/language is separated by a blank. If negotiation is
203 in effect in init-response, Option
204 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
205 Code based on patch by Vasiliy Osadchuk.
207 Fixed bug #306: infinite recursion that occurred when calling
208 yaz_log_level_init as the first call (before other log level or
211 Fixed bug in scan handling in front end server: if preferred-Position-In-
212 Response was non-present, a NULL pointer referece was performed.
216 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
217 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
218 now defined for all those error codes. So instead of putting 109 in
219 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
220 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
222 Modified the yaz-marcdump utility to skip garbage bytes between MARC
225 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
227 Program yaz-client now exits and produces an error message if multiple
228 Z39.50 servers are specified on the command line (none or one allowed
231 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
236 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
238 Fixed bug #272: Preserve spacing for CCL terms.
242 Added support for virtual hosts and multiple backend servers for
243 the YAZ frontend server. The configution is XML based and
244 support specificition of CQL to RPN mappings and explain information.
245 See section "Virtual Hosts" in the YAZ manual.
247 Extended OPAC display utility. OPAC display utility renders
248 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
249 to supplement yaz_marc_decode_wrbuf.
251 Fixed a bug in MARC decoder that could caused it to crash for some
252 invalid MARC records. More diagnostics and warnings where added in
253 XML output (warnings, etc are stored in comments).
255 --- 2.0.34 2005/02/08
257 Fixes for UNIX domain sockets. Bug #261.
259 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
261 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
262 Added yaz_marc_subfield_str which defines subfield lead string which is
263 used in YAZ_MARC_LINE format. Default string is blank+$. Added
264 yaz_marc_endline_str which defines end of fields string used in
265 YAZ_MARC_LINE format. Default string is newline.
267 Experimental support for MarcXChange. This format can be produced
268 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
269 http://www.bs.dk/standards/MarcXchange.xsd
271 Added yaz-client commands scansize that sets maximum number of
272 entries to be returned by scan.
274 --- 2.0.32 2005/01/11
276 Added support for SRW scan in yaz-client and Generic Frontend Server.
278 * Added whereInList member to SRW Scan Term.
280 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
282 Fixed NMEM system to return aligned blocks on the smallest boundaries
283 that are suitably aligned for all possible types on the particular
284 architecture YAZ is being built for.
286 --- 2.0.30 2005/01/04
288 Fixed numerious warnings that was issued with newer versions of GCC.
290 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
291 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
294 Make YAZ Generic Frontend Server slightly faster.
296 Enhance (and reduce) logging for Generic Frontend Server.
298 Revert YAZ log system so that it flushes every write operation
299 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
301 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
302 instead of LOG_, due to name clash with syslog(3). LOG_ are still
303 present. New applications should define YAZ_USE_NEW_LOG=1 - this
304 will effectively disable old definitions.
306 --- 2.0.28 2004/11/09
308 Added yaz_log_time_format which specifies log format using
311 Added yaz_log_module_level which returns mask for a module. Value
312 is non-zero mask a if module is enabled; zero if disabled.
314 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
315 in include/yaz/cql.h.
317 Fixed bug #176: Dont throw diagnostics on empty SRU args.
319 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
321 Fixed bug #172: RPM builds does not enable SSL.
323 Doxyfile.in part of dist. Doxyfile generated by configure.
325 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
326 are given and the corresponding component does not exist.
328 Extend CCL documentation in YAZ reference. Describe r=r.
330 --- 2.0.26 2004/10/01
332 Fixed MARC->MARCXML conversion to properly deal with
333 fields, subfields, indicators having non-ASCII characters.
335 Fixed MARC->MARCXML conversion so that ASCII control characters
336 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
339 Added YAZ GFS support for conversion from Z39.50 surrogate
340 diagnostics to SRW surrogate diagnostics.
342 Bug fix: YAZ GFS did not return schema in explainResponse.
344 --- 2.0.25 2004/09/30
346 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
347 now converts recordSchema to elementSetName as well as schema URI.
349 Fixed bug in COMSTACK that prevented HTTP request packages from being
352 --- 2.0.24 2004/09/29
354 Added CCL facility r=r "range" which is similar to r=o "ordered" but
355 does not require white-space before and after the dash in a range, e.g.
356 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
359 Fixed a few AC_TRY_LINK configure tests that did not operate properly
360 due to new GCC removing "redundant" code.
362 Added yaz-client commands scanpos and scanstep that sets preferred
363 position and step-size for scan.
365 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
367 Added CCL utility ccl_qual_buf which parses one or more CCL
368 spec lines in a buffer.
370 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
371 of name and value - ignoring empty lines and comments.
373 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
375 Added odr_get_element_path which returns current element path for an
376 ODR handle. This utility is useful in error handling or user-defined
379 Added ODR_PRINT utility odr_set_stream which is is a more generic
380 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
381 to a write function and pointer to close function. The close function - if
382 non-NULL - will be called during odr_destroy.
384 Fixed bug in CCL parser where truncation char was not removed from
385 right side when truncation=both was in effect.
387 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
390 --- 2.0.23 2004/08/11
392 Fix buffer overrun in CQL parser when dealing with proximity (%).
394 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
395 to UTF-8/UCS conversion is now only based on codetables.xml.
397 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
399 --- 2.0.22 2004/08/06
401 Add support for more "commit changes" in ZOOM (uses Extended Services).
403 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
406 Yet another small fix for configure of SSL.
408 --- 2.0.21 2004/05/14
410 Fix SSL libs for configure when --with-openssl=DIR is given.
412 --- 2.0.20 2004/05/10
414 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
416 SSL comstack now uses yaz.pem certificate file on server side
417 by default. Certificate filename can be configured by calling
418 comstack function cs_set_ssl_certificate_file before cs_bind is used.
420 Fix bug regarding multiple calls to ZOOM_connection_connect.
422 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
424 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
425 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
427 ZOOM now allows inspection of X509 peer certificate for verification.
428 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
430 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
431 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
432 as "modular" but it simplifies things.
434 Added cs_get_peer_certificate to that returns peer X509 PEM.
436 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
437 NULL if SSL is unavailable.
439 Documentation about MARC decoding tools.
441 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
443 --- 2.0.19 2004/03/30
445 Rename CHANGELOG to NEWS to follow GNU style packing.
447 Fix bug with missing initialization of member in init_diagnostics.
448 This bug affects threaded version of GFS server.
450 --- 2.0.18 2004/03/20
452 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
455 Ensure zlib.dll is packed with Windows install.
457 --- 2.0.17 2004/03/17
459 Fix encoding of xsd:string to use text instead of CDATA.
461 Fix endless loop in CQL parser with unbalanced ".
463 Use a more compact way to store MARC-8 conversion tables.
465 --- 2.0.16 2004/03/16 Debian only
467 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
470 Update CQL parser to use new CQL 1.1 modifiers for booleans and
475 --- 2.0.15 2004/03/01
477 Another fix for decoding of XML packed records.
479 --- 2.0.14 2004/02/25
481 Fixes for Chunked encoding. White space not ignored after length spec.
483 Update NS and use default NS for SRW diagnostic elements.
485 --- 2.0.13 2004/02/23
487 Implement ZOOM_resultset_cache_reset which resets record cache.
489 Implement ZOOM_resultset_sort which sorts a result set.
491 Implement chunked HTTP transfer.
493 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
495 --- 2.0.12 2004/02/16
497 Added member 'schema' to bend_explain_rr structure so that backend
498 can specify explain record identifier. Defaults to Zeerex 2.0.
500 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
502 --- 2.0.11 2004/02/16
504 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
507 Added init command for yaz-client which sends "extra" init request.
509 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
510 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
512 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
514 Make ZOOM error code for "invalid query".
516 Fixed compilation for SSL which wasn't properly enabled for all platforms.
518 --- 2.0.10 2004/02/05
520 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
523 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
525 Added option -p <file> to make Generic Frontend Server to write PID file.
527 Added option -D to put Generic Frontend Server in background on its own.
529 Make ZOOM C recognize option "password". If unset, "pass" is used
530 (for backwards compatibility).
532 Fixed a bug in Generic Frontend Server that could make it crash if a
533 client sets characterSetNegotation bit, but didn't pass negotiation stuff
536 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
537 Must be issued before open, in order to be in effect.
539 --- 2.0.9-6 2004/01/12 Debian/Windows
541 Make the SRU server more picky WRT unknown params, etc.
543 Bug fix: ZOOM scan response didn't return displayTerm - when present.
545 New YAZ client command, options, that sets Z39.50 options.
547 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
548 options from a string of tokens (one token for each option bit).
550 Update SRW diagnostic code messages.
552 --- 2.0.9-5 2004/01/07 Debian/Windows
554 Handle user defined stylesheet for SRW/SRU.
556 --- 2.0.9-4 2004/01/06 Debian/Windows
558 Fix bug in decoding of Content-Length.
560 --- 2.0.9-3 2004/01/06 Debian/Windows
562 Fix a bug with decoding of XML packed records.
564 --- 2.0.9-2 2004/01/05 Debian only
566 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
568 Fix bug in SRW/SRU diagnostics decoding.
572 Fixed bug in Generic Frontend Server which could drop records exceeding
573 preferred message size. Reported and fixed by Irina Dijour.
575 Fixed calculation of package size for structured records in Generic
576 Frontend Server. Reported and fixed by Irina Dijour.
578 Fixed namespace for SRW/SRU diagnostics.
580 Fixed SEGV in yaz-client that occured for HTTP connection errors.
584 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
585 this version is incompatible with version 1.0 and older YAZ SRW/SRU
588 CQL changes to reflect recent changes to the specification:
589 * Documentation talks about context sets instead of index sets.
590 * Documentation talks about indexes instead of qualifiers.
591 * The CQL-to-PQF transformer's configuration file now uses
592 "index.set.name = <attributes>" instead of the old form
593 "qualifier.set.name = <attributes>". (Both forms are still
594 understood but the latter is deprecated.)
595 * CQL terms with no explicit index specified are now interpreted as
596 cql.serverChoice instead of srw.serverChoice (which of course
597 behaves exactly the same.)
601 MARC conversion can now generate ISO2709 output in another
602 character set. yaz-marcdump uses this facility if you invoke it
605 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
606 functions from there can be used from C++.
610 Frontend server now transfers memory from decoded packages to stream
613 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
614 references to show up.
616 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
617 the ZOOM Abstract API. The older names for the same options are still
618 also supported for the benefit of old applications.
620 ZOOM-C supports "implementationId" and "implementationVersion" options
621 to go along with "implementationName". These allow the user code to
622 specify identification strings to be sent to servers.
623 Add OID for the new ExtLite attribute set.
625 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
626 as requested/supplid by Ere Maijala <ere@atp.fi>
628 For generic frontend server, reverse the order of
629 "toolkit-supplied / application-supplied" strings sent as implementationId,
630 Name and Version. Also, remove the spaces around the slash. This brings
631 the GFS in line with the behaviour of ZOOM-C on the client side.
633 Add function ZOOM_scanset_display_term.
635 yaz-client shows scan displayTerm if present.
637 Utility yaz-iconv is now installed by default along with the man page
640 Extend configure check for OpenSSL to use pkg-config where available (such
643 Incorporate patch by Morten Bogeskov which allows a Unix file socket
644 server to specify uid/gid/mask for socket using the format
645 unix:[user=uid,][group=gid,][umask=mask,]file=path
646 If file= is omitted the existing format is assumed, e.g.
648 in which case the mask is 0666 (rw for everybody).
650 Major restructure of YAZ source. All source in libyaz is in src directory.
651 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
652 util (utility programs such as ASN.1 compiler, yaz-marcdump).
654 Added man page for utility yaz-marcdump (used to be called marcdump).
655 yaz-marcdump is installed by 'make install'.
657 Fixed a memory leak in Generic Frontend Server that occurred when decoding
658 of incoming package failed.
660 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
662 Change prototype of odr_perror: add const to message string.
664 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
666 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
667 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
668 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
669 DNS lookup. There should not be any compatibility problems with this
670 assuming that blocking=1 or 0 is used.
672 Fix bad reference in UNIX comstack in function cs_addrstr.
674 Fix for compilation on AIX.
676 The generic front-end server (server/seshigh.c) now supports returning
677 Init diagnostics to the client in User-information-field, in
678 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
683 Allow any CQL relation (not just all,any,exact,scr).
685 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
686 that features the same UI.
688 Implemented command update0 in YAZ client which is equivalent to
689 update but uses old of Ext Update ASN.1.
691 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
692 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
693 Previously no OID was used for this info.
695 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
696 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
697 returns 'malformed search term' otherwise.
699 SortResponse member resultCount now set to NULL in sort handler of
702 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
705 Add three new utility functions for translating OIDs between various
706 formats -- symbolic name such as "Usmarc", minus-1-terminated int
707 arrays and dotted strings such as "1.2.840.10003.9.5.1":
708 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
709 char *oid_to_dotstring(const int *oid, char *oidbuf);
710 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
712 Reverted modifications for ES Update definition for z_IU0Update
713 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
714 is back to YAZ 2.0.2.
716 String value attributes for CCL parser.
718 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
719 which their FirstSearch server returns in Init responses, sometimes
720 carrying useful diagnostic information when Init fails. This has the
721 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
722 "z39.50/oclcui.asn", where its definition is somewhat different from
723 what OCLC document on their web-site, as required to interoperate with
726 Support for anonymous authentication in yaz-client. Use the command
729 * Fix the OID of the Index Data-local "admin" Extended Service from
730 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
731 the 1000, which indicates a locally-defined OID, was a mistake.
735 Fix CCL directive @case handling so that it affects string match for
736 both CCL keywords and qualifiers.
738 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
739 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
740 Decoder has been updated with ASN.1 changes as listed in
741 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
742 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
743 z_IUUpdate, remains unchanged.
745 ZOOM_record_get may now return a record in a specific character set.
746 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
747 "from" is the character set of record as returned by target. "to" is
748 the character set to be returned. If omitted, "to" is UTF-8.
750 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
752 New ODR utility, odr_getelement, which returns name of element for
753 which encoding/decoding failed.
755 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
756 in cases where a required element was omitted.
758 Bug fix: some MARC8 sequences were not converted.
760 New ZOOM option "step" which specifies number of records to be
761 retrieved in one chunk. Used in conjunction with "start" and "count".
763 SRW support for yaz-client. Use scheme http: to use it, e.g.
766 yaz-client no longer does (un)intelligent character set conversions
767 by default. Can be enabled with charset and marc_charset commands.
769 xmalloc trace fix for 64-bit systems such as DEC alpha.
771 Solaris 2.6 compile fix.
773 New function, cql_strerror() translates SRW error codes, as returned
774 by cql_transform_error(), into human-readable English strings. Used
775 in yaz-client diagnostics when appropriate.
777 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
778 converts it into a type-1 query which is sent to the server. This
779 makes CQL available for use with all Z-servers, as opposed to the tiny
780 minority that can handle CQL queries themselves.
784 New Debian package layout similar to the Redhat Package layout.
786 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
787 and search result respectively.
791 Redhat package is now several packages: libyaz (runtime libraries),
792 libyaz-devel (development and documentation, and yaz (utility programs).
793 Package spec file by Morten Bøgeskov.
795 New member 'schema' in struct bend_fetch_rr which the name of requested
796 schema (SRW/SRU) for record (or NULL if none was given). The fetch
797 handler MAY set this to reflect the schema of the returned record.
799 New member 'display_term' in struct scan_entry. GFS now sets member entries
800 and allocates scan entries to be filled by user scan handler. In previous
801 version, entries member was allocated by the scan handler. That still works,
802 but the GFS will ignore member display_term - assuming it was NOT set by
803 the handler. The fact that the GFS now allocates the entries both allows
804 for new members and makes a scan handler easier to write.
806 Fix CQL lex buffer overflow.
808 SRW/SRU recordPacking. For SRW default recordPacking is string. For
809 SRU default recordPacking is string.
811 SRU protocol support for frontend server.
813 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
815 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
817 Added scan for the ZOOM shell (zoomsh).
821 * String Identifers for Schemas (Amendment 5).
822 http://lcweb.loc.gov/z3950/agency/amend/am5.html
823 Old definition for schema
824 Odr_oid *schema; /* OPT */
829 Z_InternationalString *uri;
830 #define Z_Schema_oid 1
831 #define Z_Schema_uri 2
834 * resultCount parameter to Sort Response (Amendment 1).
835 http://lcweb.loc.gov/z3950/agency/amend/am1.html
837 Support for SRW 1.0 over HTTP. This is an optional feature and
838 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
841 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
842 on the same port. SRW SearchRetrieveRequests are mapped
843 to bend_init,bend_search,bend_fetch,bend_close.
845 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
847 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
848 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
850 ZOOM connections are SRW based if schem http is used for hostname
851 in connect, e.g. z = ZOOM_connection_new("http://myserver");
852 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
854 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
855 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
856 distance=n, order=true/false, relation=le, prox unit=word. If
857 n is omitted, distance 1 is used.
859 Fixed problem with C compiler include path in wrong order.
861 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
862 on Solaris. Patch from Ko van der Sloot.
864 New MARC decode API. All new functions operate on a yaz_marc_t
865 handle. The most important new functions are: yaz_marc_create,
866 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
867 decode and destroy respectively. Decoder can produce formats
868 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
869 include/yaz/marcdisp.h.
871 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
872 to UTF-8, UCS-32, wchar_t or Latin-1.
874 * Prototypes for yaz_iconv_-functions moved to separate header
875 include/yaz/yaz-iconv.h.
877 Make a few private functions 'static' in unix.c. This prevents
878 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
880 For ZOOM connection, the options targetImplementation{Id,Name,Version}
881 are set when Init Response is received.
883 New function ZOOM_connection_error_x similar to ZOOM_connection_error
884 but returns diagnostic set as well.
886 New function yaz_strerror which is a portable wrapper for
887 strerror/strerror_r/GetLastMessage.
889 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
890 is returned for MARC. If type is "oai", then OAI MARC is returned.
892 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
897 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
899 Fix bad race conditions on SIGTERM and terminate gracefully in
902 Move retrieval (data1) module to Zebra since nobody seems to be
905 Add GRS-1 render for ZOOM using same format as yaz-client.
909 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
911 Fix broken ESpec handling in data1 module.
913 SGML reader parses comments and makes them part of the data1 tree.
915 Added several type casts so that YAZ compiles as C++ code.
917 ZOOM didn't handle PDU encoding failures properly.
919 Added more Bib-1 diagnostics (approved extensions).
921 GNU configure: better check for iconv.
923 More portable use of accept, getpeername. Check for socklen_t. Use
924 int/size_t if socklen_t is not defined.
928 PQF parser rejects bad queries - including those with extra
929 characters in them. PQF parser used to silently ignore that.
930 Cleaner API for PQF added, which allows you to get detailed
931 error information for bad queries (see yaz/pquery.h).
933 Fixed bug in ZOOM_record_get for type "database".
935 Implemented mini iconv library supporting conversions between
936 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
938 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
942 Fixed ZOOM C record cache so that preferredRecordSyntax and
943 elementSetName is used to check for already fetched records.
947 Added three members in bend_initrequest structure to facilitate
948 character set negotiation.
950 Fixed a bug in frontend server that could cause indefinite
951 loops under rare conditions.
953 Revised character set utilities (charneg.h) so that encoding
954 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
956 For PQF, directive @term <type> sets term type for Scan/Search.
957 Here <type> is general, string, numeric, null. The term type
958 is inherited - just like @attr.
960 New call odr_set_charset that sets character set conversion for
961 international-strings on a ODR stream. Prototype is:
962 int odr_set_charset(ODR o, const char *to, const char *from);
963 The InternationalString is still represented as C string in YAZ
964 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
965 won't). On the protocol level, you can use any encoding.
967 Support for UNIX sockets in ZOOM.
969 Solaris recv sometimes returns errno == ENOENT. It is treated as
970 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
972 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
973 both client and server. Code by Morten Bøgeskov.
977 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
978 that they can be used directly from Visual Basic. You must recompile
979 your windows APP if you're using ZOOM.
981 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
982 Commands "lang" and "charset" sets language and character set respectively.
983 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
984 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
986 Attributes from multiple CCL fields may be OR'ed rather than merged
987 using directive "@field or". Fields are still merged by default -
988 equivalent to "@field merge".
990 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
993 Fixed bug in zget for parameter ExtendedServicesResponse.
999 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1001 Client displays USR.1:SearchResult-1 (hits per term).
1003 Additional Search Info for search in Generic Frontend Server.
1005 Fixed CCL parsing of "field=s".
1007 WIN32 installer - using the excellent NSIS software from nullsoft.
1009 Fixed CCL parsing of "field = - <number>".
1011 Added function yaz_marc_decode that decodes MARC for line mode
1012 display or XML (similar to that used by JZKit).
1014 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1015 Z39.50. But ISO/ILL was, however.
1017 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1018 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1020 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1021 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1023 --- 1.8.5 2002/02/03
1025 New YAZ client features: Command completion and new commands:
1026 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1027 Code provided by Jacob Poulsen.
1029 New call oid_trav, that visits all registered OIDs via callback.
1031 Function ZOOM_record_get now returns const char pointer rather than
1032 void pointer. It saves a lot of type casts.
1034 For YAZ client, command "auth" now allows you to set authentication
1035 in IdPass style. It is enabled when three tokens are given - order
1036 is user, group and password.
1038 Fix memory leaks in MARC record handling for ZOOM.
1040 New option for YAZ client, -k <kilobytes> that sets
1041 maximum record size. Similar to -k option for generic frontend
1042 server and yaz-ztest.
1044 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1046 Prefix query parser reports "fail" when bad attribute set is given.
1048 Fix in MARC decoder. Proximity logging. Fix for attribute set
1049 in scan handler for server. Patches by Shigeru Ishida.
1051 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1054 Configure option --with-openssl=<dir> now works when a directory is
1055 specified. Patch provided by Morten Bøgeskov.
1057 New option for YAZ client, -u <auth>, that sets authentication.
1059 ZOOM fix: error information was sometimes "missing", since error
1060 was cleared/reset too when it shouldn't.
1062 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1064 --- 1.8.4 2002/01/04
1066 Scan for ZOOM API. New object ZOOM_scanset. New functions
1067 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1068 ZOOM_scanset_destroy.
1070 New ZOOM function, ZOOM_connection_last_event, that returns type
1071 of last event (such as "receive data", "send data", "apdu received",
1074 New ZOOM option, schema, that specifies schema for retrieval.
1076 New CCL feature. Qualifiers can be aliases for one or more
1077 other qualifiers (if more than one is given, OR is used).
1079 ZOOM uses named result sets if target supports it.
1081 Two new YAZ client commands: . (dot, which sources a script of YAZ
1082 client commands), and ! (to execute shell command.). Implemented
1085 Working on Debian packages.
1087 --- 1.8.3 2001/11/19
1089 YAZ client enables named result sets only if target supports it.
1091 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1093 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1094 with key="host" to get same result.
1096 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1097 Function Z3950_resultset_record(s) returns references to records
1098 "owned" by resultset. To become owner use Z3950_record_clone.
1100 Function z_ext_record handles Extended Services. Thanks to
1103 --- 1.8.2 2001/11/12
1105 CCL Parser fix: ignore token comma when dealing with and-lists.
1107 Documentation updates for COMSTACK.
1109 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1110 Changed prototype Z3950_records. For some functions, int parameters
1111 were changed to size_t.
1113 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1116 New MARC decode/display function, marc_display_exl, which properly rejects
1117 non-ISO2709 records. YAZ client uses it.
1119 --- 1.8.1 2001/10/29
1121 Fix bug: local attribute set wasn't set correctly in PQF strings.
1125 * Old Z39.50 codecs no longer supported.
1127 Added ZOOM C binding. See http://zoom.z3950.org/
1129 Renamed states for COMSTACKs to avoid confusion with events.
1131 Implemented cs_look and proper cs_rcvconnect.
1133 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1135 Configure detects POSIX threads on OpenBSD.
1137 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1138 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1140 When error is returned from present handler, non-surrogate diagnostic
1141 is returned in present response (and fetch handler is no longer called).
1143 * Minor adjustments to pquery parser (PQF). Token characters may be
1144 escaped by using backslash (C-style).
1146 PQF parser allows string attribute values to be specified. For @attr,
1147 non-numeric characters after the equal-sign are treated as strings
1148 (e.g. @attr 9=title).
1150 CCL trunction character may be defined (@truncation in file)
1152 * function zget_ExtendedServicesRequest sets waitAction to
1153 waitIfPossible (was wait).
1155 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1158 CCL operator names may be set in field definition files (CCL_bibset).
1159 See ccl/bib1 for an example.
1161 Fixes in ASN.1 compiler for C++ compatibility.
1163 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1164 and "op_or" to avoid conflict with C++.
1166 Fixed problem with GNU readline detection on Redhat 7.0.
1168 Added step-size for Scan backend handler.
1170 Fixed bug that made the frontend server crash when no attribute
1171 set was specified for scan.
1173 Front-end server automatically switches to original working directory
1174 when installed as an NT service. Previously -w had to be specified to
1177 Added extended attributes for retrieval module (data1), so that data1
1178 records carry d1_readXML/SGML attributes. d1_read also supports
1179 null-data rules ( <tag/>)
1181 On UNIX when POSIX threads are available, a separate library libyazthread
1182 is created. Programmers should link with that library and the yaz library
1183 when using threads. The reason for the split was that some applications
1184 on Linux, such as Apache, doesn't work well when using shared objects that
1187 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1188 (or any frontend server) in SSL mode by specifying ssl: followed by
1189 address. Only tested on UNIX.
1191 Added feature for CCL module. Virtual structure s=al or s=ol generates
1192 and-list and or-list respectively instead of phrase search.
1196 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1197 log_mask_str. This was done to avoid name conflicts with other libraries
1198 (such as other PHP extensions).
1200 Added raw OID member for preferred record syntax (request_format_raw)
1201 and returned record syntax (output_format_raw) for backend fetch method.
1203 Config file yaz-config now accepts options so that it returns specific
1204 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1206 Shared library support for UNIX using GNU libtool.
1208 * Modified backend interface. Request/Response struct's replaced by
1209 one read/write C struct. For example bend_fetchrequest and
1210 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1211 Every handler - even search has to be registered in bend_init
1212 handler. This means that the YAZ library no longer refers to
1213 external functions and it makes it possible to make the whole
1214 thing a single DLL/SO.
1216 Added Segment handler for backend server.
1218 Added Zmbol/Zebra administrative functions to YAZ client.
1220 Threaded frontend server on UNIX (when POSIX Threads are available).
1221 Starting the server with option -T enables multi-threading.
1225 Added configure option --enable-comp/disable-comp to control use
1226 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1227 located in sub directory asn.
1229 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1230 in ${exec_prefix}/bin along with the other programs yaz-client and
1233 GNU automake used to maintain makefiles.
1235 Added several OID's.
1237 Changed retrieval module so that we can load records with no abstract
1238 syntax defined. Tagpaths in these records are fully composed of string
1241 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1245 On UNIX, the generated makefile now supports a proper 'make install'.
1246 The prefix can be set via GNU configure to set the install location
1247 (default is /usr/local).
1249 * YAZ programs client and ztest were renamed to yaz-client and
1250 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1251 locations, such as /usr/bin,/usr/local/bin,etc.
1253 * YAZ Header files were moved from include to include/yaz. YAZ Header
1254 files are referred to as include <yaz/log.h> rather than <log.h>.
1255 The YAZ include path (-I ..) is therefore the same as before. Programmers
1256 should update their #include statements or use -Ipath/include/yaz
1257 instead. The main motivation for doing this change is that YAZ header files
1258 can be installed in "standard" locations /usr/include,/usr/local/include
1259 without introducing conflicts, since ALL YAZ header files are stored
1260 in subdirectory yaz (under /usr/include for example).
1262 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1263 rather than project/workspace files. We switched because project files
1264 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1267 Changed name of logging function, logf, to yaz_log, to prevent name
1268 clash with some math-log functions. The YAZ header log.h defines logf
1269 to yaz_log (#define) so there should be no incompatibilities by this
1272 Added bend_start/bend_stop handlers for server. These handler are
1273 called on start/stop of server. For windows they are called whenever
1274 a service is started/stopped.
1276 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1277 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1278 in util/yc.tcl. The auto-generated C code structures are, in a few
1279 cases, incompatible with the old decoders. There are differences in the
1280 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1281 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1282 The preprocessor variable ASN_COMPILED is defined when the compiled
1283 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1284 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1285 wish to use the old encoders/decoders you can specify --disable-yc
1288 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1289 version so that it supports both new - and old version of DB Update
1291 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1292 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1293 change. The name parameter can be set to 0 in which no name is specified
1294 for the construction. The macros odr_implicit and odr_explicit sets name
1295 parameter to zero for the construction involved. New macros
1296 odr_implicit_tag and odr_explicit_tag are similar to the others,
1297 except that a name parameter is added. For programmers' that don't use
1298 ODR they probably only need to change the call to z_APDU and z_External.
1300 Added access control facility by interfacing the TCP wrapper library.
1301 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1302 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1303 name of the daemon and enables the access control as specified in
1304 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1306 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1307 den Dool <H.M.vdnDool@kub.nl>.
1309 Added reference ID parameter to most functions in server API - refer
1310 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1312 Changed name of ccl library to libccl.a (was ccl.a).
1314 Fixed bug in decoder for Explain (Category TargetInfo).
1316 Added support for GNU readline in client. Thanks to Jacob Poulsen
1317 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1319 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1320 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1321 IMPLEMENTATION! This change was made to the development version before
1322 the ZIG decided to retract the amendment. If any users MUST be
1323 compatible with the original Update definition, PLEASE CONTACT US, and
1324 we will include a separate definition corresponding to the old Update
1325 ES. Note that because of the change to the ASN.1 of the
1326 TaskPackageRecordStructure we cannot define a single structure that
1327 will support both versions.
1329 * Added const modifier to buffer parameter for some ODR/BER encoding
1330 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1331 completeWAIS, odr_dumpBER.
1333 Fixed bug in client.c which caused a crash when a scanResponse didn't
1334 contain positionOfTerm.
1336 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1337 * will cause an error in a client if a non-YAZ target sends both a
1338 * list of Scan entries and non-surrogate diagnostics.
1340 Retrieval module enhancements. Tag sets may be typed in the reference
1341 to it. From the .abs-file the "tagset" directive takes a third optional
1342 integer type for the tag set referenced. From a .tag-file the "include"
1343 directive takes a third optional type as well. The old "type" directive
1344 in the tag set itself is still recognized but acts as the default type
1347 Backend interface change. Individual Scan terms returned from bend_scan
1348 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1349 in include/backend.h.
1351 Retrieval module enhancements. Multiple tag sets and attribute sets may
1352 be specified in abstract syntax specs. Revised the error/warning for
1353 logging messages reported by the retrieval module when reading the
1356 Object Identifier system (oid_..) changed. The API is backwards
1357 compatible but the oid-routines now allocates new OID's when needed.
1358 Raw OID's may be specified in oid_getvalbyname.
1360 YAZ now uses GNU configure to generate Makefile(s).
1362 * Minor changes in some of the member names of DeleteResultSetRequest and
1363 DeleteResultSetResponse. See include/proto.h.
1365 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1366 and added member 'languages' in TargetInfo (which was missing).
1368 Changed the way attribute sets are handled in the retrieval
1369 module. These are now cached, just like the abstract syntaxes
1372 Changed YAZ so that it links with compiled ASN.1.
1374 Added Explain-schema definitions and mapping routines. The following
1375 Explain categories have been implemented: AttributeDetails,
1376 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1378 Fixed minor bug in Windows version of Server Library.
1380 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1382 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1384 Added EXTERNAL: UNIverse Resource Report (non-standard).
1386 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1387 ENUMERATED and SET OF.
1389 * Added 'const' to some of the char pointer arguments for the
1390 functions, data1_read_node, data1_getelementbytagname,
1391 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1394 Fixed bug in data1_insert_taggeddata - the last_child member of
1395 parent wasn't initialised.
1397 * Changed data1_read_record and data1_read_node so that the supplied
1398 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1399 doesn't refer to any parts of the "SGML"-buffer.
1401 Fixed bug in server library (Windows version of statserv_remove).
1403 * Changed code so that it compiles as C++. The type definition
1404 of Odr_fun which is a member of Odr_arm was changed. The result is,
1405 that an explicit typecast is needed for the fun pointer when
1406 using Odr_arm - as in:
1407 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1409 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1411 Implemented the new structured date and time definition as approved
1412 by the ZIG. Added schemaId element to the specificTag in Espec-1
1413 (also approved at the last ZIG). Thanks to RVDM.
1415 Added some Object identifiers (RVDM).
1417 Changed the Update Extended Service (RVDM).
1419 Added command "refid" to client which specifies referenceId for
1420 the following requests.
1422 Implemented extended service handling for server. See ztest.c
1423 for an example as well as backend.h. New handlers are registerd
1424 in the Init handler.
1426 * Changed interface for sort in server.
1428 Added new members to statserv_options_block. It allows a server
1429 to read options from another source than just the command line. Thanks
1430 to Charles Woodfield.
1432 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1433 renamed to zboolean. Some C++ compilers complained about the name.
1435 Minor changes to gils.abs. Added index 's' (sort) on title
1436 and date/time-last-modified.
1438 --- 1.4pl2 1998/1/30
1440 Fixed bug in server library regarding inetd mode (-i). This bug
1441 was introduced by release 1.4.
1443 --- 1.4pl1 1998/1/29
1445 Added sort facility in client and backend server interface.
1447 Fixed problem with dependencies in Makefile(s).
1449 Fixed bugs for encoders/decoders of extended services and
1452 Implemented sub-tree feature for schemas. Sub-trees are
1453 referenced in *.abs-files. See explain.abs for an example
1454 of the use of this feature.
1456 Modified bib1.att; local attributes for ANY didn't include
1457 ANY itself (only affects use of the retrieval module).
1459 Fixed bug in plain SGML reader in function data1_read_node:
1460 tags with prefix "var" was incorrectly interpreted as variants.
1462 Added feature "sub-schemas" to enable references to - and definitions
1463 of - group of elements.
1465 * Removed member parent from type data1_element (in data1.h).
1467 Implemented function odr_nullval() that returns the value of
1470 * Removed member num_children from data1_node (in data1.h).
1472 Made NT service interface part of the server library. The
1473 function statserv_main uses the NT service when required and
1474 calls the statserv_start / statserv_close routines.
1476 Routine zget_SearchRequest and zget_PresentRequest fills
1477 resultSetName/Id member with "default" instead of "Default".
1479 Fixed memory leak in server. Request queue member wasn't freed.
1481 Fixed nmem_exit so that memory is freed.
1485 Revised the CCL parser utility to be thread safe.
1487 Added function, oid_ent_to_oid, to replace the function
1488 oid_getoidbyent, which is not thread safe.
1490 * Added nmem_init and nmem_exit to initialize and release
1491 NMEM resources. Function nmem_init should be called once in the
1492 initial thread before NMEM/ODR is used. statserv.c and client.c
1493 have been changed accordingly. The change was necessary to make
1494 NMEM thread safe. The NMEM memory pool is shared amongst threads
1495 in a process. Unix-based applications will still work fine without
1498 Added NT Services interface for the the Z39.50 (statserv) Server.
1499 Refer to the ztest.c source on the usage.
1501 Windows 95/NT port using MSVC5.0. Project files are included in the
1504 * Defined new 'global' handle for the retrieval (data1) system. The
1505 new handled, data1_handle, describes the state of the data1 system.
1506 This handle is passed as first argument to virtually all
1507 data1 related routines. The functions data1_create and data1_destroy
1508 creates and destroys a data1 handle respectively.
1510 Added ODR encode stream member to all backend request structures
1511 init, search, scan etc. This stream should be used to allocate all
1512 memory used for the response when thread safe operation is needed.
1514 Changed the comstack utility, cs_addstr, to be thread safe. The
1515 returned hostname string returned by the function is now part the
1518 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1519 function. The cs_straddr takes a COMSTACK handle as argument, so this
1520 function must be used after cs_create and before bind/connect.
1521 This function is thread safe.
1523 Moved test server to 'ztest' directory - generic server code still
1524 in 'server' directory.
1526 Made prefix query (pquery.c) utility thread safe.
1528 Added new function modifier YAZ_EXPORT to 'export' public DLL
1529 functions when using windows (see include/yconfig.h).
1531 Added definitions to the OID database (util/oid.c) (RVDM).
1533 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1535 Added call to ccl_rpn_delete in client program.
1537 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1538 release of RPN structure.
1540 Added support for C++, headers uses extern "C" for public definitions.
1541 With input from RVDM.
1543 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1544 Thanks to Ronald van der Meer (RVDM).
1546 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1548 Added support for private extensions to the OID database
1549 (oid_setprivateoids()). Thanks to RVDM.
1551 Added optional, physical ANY (key replication)
1553 Fixed null-reference problem in GRS-1 output filter.
1555 Proximity operator added to Prefix Query Format (PQF).
1557 In test client command "base" accepts multiple databases.
1559 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1563 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1565 Smallish bug-fixes in the new encoders/decoders (explain).
1567 Bug fixed in DeleteRequest.
1569 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1571 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1573 Added SOIF syntax (using private OID for now) to retrieval module and client.
1575 Added Update extended service.
1577 Added SearchResult-1 additional info structure.
1579 Added optional CCL (ISO8777) interpreter as separate module. Available
1582 --- 1.2 1996/6/10 (1st anniversary release)
1584 Added Summary record syntax. Lightly tested.
1586 Added OPAC record syntax. Untested.
1588 Added ResourceReport service encoders/decoders. Untested.
1590 Fixed bug in z_Unit - wrong tagging on unitSystem.
1592 Fixed bug in the DiagRecs decoder.
1594 Added options for max PDU size and session timeout to frontend-server.
1596 Added documentation of query-language parsers and other supporting utilities.
1598 [frontend-server] Added Attribute set to the bend_scanrequest API.
1600 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1601 surrogate diagnostics were generated.
1603 [retrieval] Allow multiple local values for attribute.
1605 [retrieval] Allow multiple attributes per element in .abs files. index type.
1607 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1609 --- 1.1pl2 1996/4/10
1611 Minor changes, mostly specific to Zebra's requirements (retrieval)
1615 Repaired bug in frontend server when running multiple listening
1616 endpoints in dynamic mode.
1618 z_External() now won't break if a known, ASN.1 value comes encapsulated
1619 in an octet-string. The value will pass through unmodified in an Odr_oct.
1621 Added a bit of code to the demo client to decode & display
1622 ASN.1-structured records represented in the octet-aligned branch of
1623 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1625 Added z_ext_getentbyref() to the ASN module. Doc updated.
1627 * Completed the SCAN definition in the ASN module. This may break SCAN
1628 code based on older YAZ-versions at compile-time. The fix is easy -
1631 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1632 under the SCAN definition. Remember to initialize this, server-people.
1634 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1635 that this does not extend to ODR and ASN.
1637 Comstack allows insertion of established socket (primarily for
1638 inetd-operation of servers). Doc updated.
1640 Front-end server can now start from the inetd in TCP mode. Doc
1643 --- 1.0pl4 1996/1/24
1647 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1648 the rank and record number.
1650 Adjustments to the frontend server.
1652 Fixed diagnostic BER dumper. It ignored the file argument.
1656 Various changes to retrieval module.
1658 Changed the union discriminators of the protocol files from enums to
1659 ints paired with #defines.
1661 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1664 *Changed operator in the RPN structure to 'roperator', again to avoid a
1667 Fixed problems in Explain decoders/encoders.
1669 --- 1.0pl2 1995/12/6
1671 Memory bug in log module fixed.
1673 --- 1.0pl1 1995/12/5
1675 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1677 Bug in Explain DatabaseInfo module fixed.
1679 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1683 The shift to v1.0 signals that we now consider the *core* functionality
1684 of YAZ reasonably stable (the core being more or less equivalent to
1685 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1686 tested (Explain not at all - though that will happen soonish).
1688 Minor changes to code to support Windows port.
1690 Various minor changes after we're getting to use GRS-1 & co. more.
1692 Added Espec-1 format.
1694 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1695 of the protocol and it cannot be selected when encoding (maps into 'string'
1696 when decoding). Needed to talk to some servers.
1698 Demo client can request simple element set names.
1700 Added Diagnostic Format encoders/decoders.
1702 Added simple Close handling to frontend server (no hooks for resource
1703 reporting yet), and demonstration client.
1705 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1707 --- 1.0b3 1995/08/24
1709 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1710 handled incorrectly when records were requested in the searchResponse. This
1711 will only affect you if you use the frontend-server.
1713 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1714 Test-client will ask for and print GRS1. Ztest will return dummy records
1717 Added Explain encoders/decoders to the service-level API. Untested.
1719 Added Extended Services: Item Order encoders and decoders to the Service-
1720 level API. Untested. We could use a recent copy of the pertinent bits
1721 of the ILL protocol to add those bits.
1723 Added diagnostic format 1 encoders/decoders to the service-level API.
1726 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1727 odr_cons.c, which causes a more correct output.
1729 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1730 was always set to 0 when no records were requested in the searchRequest.
1732 * Added better external-handling. This shouldn't harm old code that
1733 *encodes* externals. It can break code that looks for a
1734 'single-ASN1-type' representation, since those types that are known
1735 are now decoded immediately. Look at the SUTRS sample code in
1736 seshigh.c and client.c. Documentation updated.
1738 Handling of structured records in bend_fetchresponse. Length -1 marks
1739 structured record, type is deduced from format field.
1741 --- 1.0b2 1995/06/27
1742 Fairly quick maintenance release to add SUTRS support.
1744 Fixed handling of SUTRS records in the demonstration client.
1746 * Added format field to the bend_fetchrequest and bend_fetchresponce
1747 structures of the backend API (frontend server). When the record is
1748 returned, the value of the format field is mapped to an OID. The
1749 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1750 of the record. The special value VAL_NONE in the bend_request means
1751 that no specific format was requested by the client. Documentation
1752 updated accordingly. Test server (ztest) will return a fixed dummy
1753 SUTRS record if your client requests SUTRS.
1755 Documentation updated accordingly.
1757 You can now set external libraries and RANLIB support in the top-level
1761 First public release.
