3 Bug #600: SRU GET, POST support for yaz-client. Introduced
4 command 'sru' which selects method SOAP/GET/POST.
6 Allow missingValueAction to be specified for the sortspec string -
7 function yaz_sort_spec. By default, the missing value action is null.
8 Use ! to specify "abort". Use = followed by stringvalue to specify default
11 Ensured that Present-handler (if defined) is called in GFS before any call to
12 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
13 searchRetrieve requests.
15 Documentation for YAZ is now based on the Docbook XML/XSLT using
16 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
17 is no longer depending on jade/openjade or docbook-to-man scripts.
18 PDF is no longer part of the distribution - but can optionally be
19 made using DSSSL/jadetex or FOP.
21 Added retrieval handling support in Generic Frontend Server to support
22 conversion between MARC/XML as well as XSLTtransforms. See
23 etc/yazgfs.xml for an example.
25 Added Authentication support to Generic Frontend Server in SRU
26 mode. Authentication using HTTP Basic is supported, as is the use
27 of 'x-username' and 'x-password' parameters in the request itself.
29 Added support for a new character set MARC8s identical to MARC8 except
30 that it converts combined characters to single Unicode characters in the
31 Latin-1 range (when possible).
35 ASN.1 compiler 0.4: generates brief Doxygen file header for
36 generated .h/.c files.
38 Utility yaz_iconv now supports conversion to MARC-8.
40 New facilities for the MARC module. The reading - and writing of
41 content are separate methods for the yaz_marc_t handle. The following
42 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
43 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
44 format). Write functions have prefix yaz_marc_write_.. The existing
45 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
46 available. Removed support for OAI-MARC and simplexml (not the
49 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
50 to be returned for this connection.
54 Allow multiple languages and charsets to be specified with
55 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
56 negcharset iso-8859-1,utf-8
58 Translation of proximity nodes from CQL into PQF now works.
60 Moved to automake 1.8, 1.9.
62 Added function yaz_log_set_handler which allows a log handler to be
63 installed. This handler will be called for all log messages. Output
64 to file is also produced; but that can be disabled by passing NULL
65 fname to yaz_log_init_file.
67 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
69 For SRW (including GFS), accept application/soap+xml as content-type
72 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
73 produces NO stylesheet reference even if a default stylesheet is specified
78 Updated Windows package to include yazd.dll + yazd.lib for the
79 Development component.
81 If the environment variable YAZ_LOG is set, then it is used as a
82 string indicating the default level of logging to use if not
83 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
84 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
85 used as before. So, for example, to omit warnings from YAZ logging,
88 cql_transform() now map structure and other attributes before indexes,
89 so that index-specific structures and other attributes can override
90 defaults. So now a combination of mapping specifications such as:
92 index.dc.date = 1=date-modified 4=5
95 cql_transform() now also respects the "always" mapping specification,
96 which establishes an initial set of attributes to be used for all
97 terms except where overridden by more specific attributes associated
98 with the index, relation or modifier.
100 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
101 which mode to use; one of "post", "get" or "soap" (SRW, default).
103 Fixes for yaz_iconv routines: changed trie-based character set conversions
104 to use only non-negative values for bit fields due to Sun's C compiler not
105 supporting negative values.
107 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
108 sequences where not read correctly. Fix by Rustam Usmanov.
110 Updated win/makefile to use options, settings which makes things
111 compile with VS C 2005.
113 --- 2.1.12 2006/02/01
115 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
117 In ZOOM socket code, use select instead of poll on MacOSX.
119 ZOOM-C now support client-side compilation of CQL into RPN that is
120 sent to the server, enabling CQL to be used against all Z39.50
121 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
122 ZOOM_query object, and submit it using ZOOM_connection_search().
123 The CQL-to-RPN translation uses a configuration file, the name of
124 which must be specified in the Connection's "cqlfile" option.
126 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
127 function, which takes as its start-term parameter a ZOOM_query object
128 (which may have had either CQL or RPN set into it).
131 --- 2.1.10 2005/11/29
133 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
134 GFS to support this as well. Backend handler, bend_srw_update, does the
135 update work. Code contributed by Ko van der Sloot.
137 Allow retrieval of Search Result-1 information in ZOOM by the use of
138 options that are attached to a result set. ZOOM documentation updated
141 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
142 UTF-8 conversion. Patch by Raj Patel.
144 Added option -m to GFS to control formatting of timestamps in log file.
146 Added 'exit' as synonym for 'quit' in yaz-client
148 Added support for specifying SRW resultSetId + resultSetIdleTime in a
149 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
150 for the new members. Patch by Ko van der Sloot.
152 Added support for SRU POST. It is supported for content-type
153 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
155 Do not build the separate Multi-threaded (MT) library libyazthread.la.
156 Instead make the library libyaz.la multi-threaded. Threading as a whole
157 can still be disabled by configure option --disable-threads. Previosly,
158 with older GLIBCs there were problems with MT libs under Apache. This
159 has now been fixed a long time ago.
161 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
164 CQL module modified to be case insensitive for relations/indexes/operations.
166 Fixed bug in CQL transform code: incorrect value relationModifieder
169 Added 'show all' command for yaz-client which retrieves all results
172 Added new yaz-client, xmles, which takes a (private) OID and
173 a document to be sent as an extended service request.
175 Describe new yaz-client commands wait_response and set_auto_wait.
177 Increase TCP/IP listener backlog from 3 (which I am guessing was
178 copied from the SunOS manual entry way back when) so SOMAXCONN, so
179 that the socket will queue as many incoming connections as it's able
180 to handle ongoing connections. In other words, it will never now
181 refuse a connection that it would be able to handle merely because
182 it's not got around to accepting() enough of the pending connections
183 yet. This is the behaviour anyway under Linux, where the listen()
184 argument is ignored; but not under BSD and on systems such as
185 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
186 YAZ-based servers should now be uniform across operating systems in
189 yaz-marcdump uses 64-bit file access on some systems. This is enabled
190 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
191 This allows yaz-marcdump to read large MARC batches (>2 GB).
193 Modified all YAZ source files - except the source which is auto-generated
194 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
197 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
198 corresponding to the existing *_setl() function. These allow option
199 values containing arbitrary valuues.
201 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
202 ZOOM_resultset_sort() in new applications. Its behaviour is identical
203 except that it returns an indicator of whether or not the sort
204 criterion was accepted (0 for OK, -1 for invalid).
208 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
209 MARC output rather than returning "new" buffer.
211 yaz-client warns about unknown init options.
213 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
217 Added support for SRW sort in Generic Frontend Server. Patch
218 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
219 sortKeys - or NULL if none is provided.
221 Fixed bug #307: It was impossible to specify indefinite/no timeout
222 for ZOOM_event. Special timeout value -1 now means indefinite timeout
225 Added support for multiple languages and charsets to be specified in
226 ZOOM. Each charset/language is separated by a blank. If negotiation is
227 in effect in init-response, Option
228 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
229 Code based on patch by Vasiliy Osadchuk.
231 Fixed bug #306: infinite recursion that occurred when calling
232 yaz_log_level_init as the first call (before other log level or
235 Fixed bug in scan handling in front end server: if preferred-Position-In-
236 Response was non-present, a NULL pointer referece was performed.
240 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
241 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
242 now defined for all those error codes. So instead of putting 109 in
243 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
244 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
246 Modified the yaz-marcdump utility to skip garbage bytes between MARC
249 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
251 Program yaz-client now exits and produces an error message if multiple
252 Z39.50 servers are specified on the command line (none or one allowed
255 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
260 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
262 Fixed bug #272: Preserve spacing for CCL terms.
266 Added support for virtual hosts and multiple backend servers for
267 the YAZ frontend server. The configution is XML based and
268 support specificition of CQL to RPN mappings and explain information.
269 See section "Virtual Hosts" in the YAZ manual.
271 Extended OPAC display utility. OPAC display utility renders
272 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
273 to supplement yaz_marc_decode_wrbuf.
275 Fixed a bug in MARC decoder that could caused it to crash for some
276 invalid MARC records. More diagnostics and warnings where added in
277 XML output (warnings, etc are stored in comments).
279 --- 2.0.34 2005/02/08
281 Fixes for UNIX domain sockets. Bug #261.
283 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
285 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
286 Added yaz_marc_subfield_str which defines subfield lead string which is
287 used in YAZ_MARC_LINE format. Default string is blank+$. Added
288 yaz_marc_endline_str which defines end of fields string used in
289 YAZ_MARC_LINE format. Default string is newline.
291 Experimental support for MarcXChange. This format can be produced
292 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
293 http://www.bs.dk/standards/MarcXchange.xsd
295 Added yaz-client commands scansize that sets maximum number of
296 entries to be returned by scan.
298 --- 2.0.32 2005/01/11
300 Added support for SRW scan in yaz-client and Generic Frontend Server.
302 * Added whereInList member to SRW Scan Term.
304 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
306 Fixed NMEM system to return aligned blocks on the smallest boundaries
307 that are suitably aligned for all possible types on the particular
308 architecture YAZ is being built for.
310 --- 2.0.30 2005/01/04
312 Fixed numerious warnings that was issued with newer versions of GCC.
314 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
315 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
318 Make YAZ Generic Frontend Server slightly faster.
320 Enhance (and reduce) logging for Generic Frontend Server.
322 Revert YAZ log system so that it flushes every write operation
323 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
325 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
326 instead of LOG_, due to name clash with syslog(3). LOG_ are still
327 present. New applications should define YAZ_USE_NEW_LOG=1 - this
328 will effectively disable old definitions.
330 --- 2.0.28 2004/11/09
332 Added yaz_log_time_format which specifies log format using
335 Added yaz_log_module_level which returns mask for a module. Value
336 is non-zero mask a if module is enabled; zero if disabled.
338 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
339 in include/yaz/cql.h.
341 Fixed bug #176: Dont throw diagnostics on empty SRU args.
343 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
345 Fixed bug #172: RPM builds does not enable SSL.
347 Doxyfile.in part of dist. Doxyfile generated by configure.
349 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
350 are given and the corresponding component does not exist.
352 Extend CCL documentation in YAZ reference. Describe r=r.
354 --- 2.0.26 2004/10/01
356 Fixed MARC->MARCXML conversion to properly deal with
357 fields, subfields, indicators having non-ASCII characters.
359 Fixed MARC->MARCXML conversion so that ASCII control characters
360 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
363 Added YAZ GFS support for conversion from Z39.50 surrogate
364 diagnostics to SRW surrogate diagnostics.
366 Bug fix: YAZ GFS did not return schema in explainResponse.
368 --- 2.0.25 2004/09/30
370 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
371 now converts recordSchema to elementSetName as well as schema URI.
373 Fixed bug in COMSTACK that prevented HTTP request packages from being
376 --- 2.0.24 2004/09/29
378 Added CCL facility r=r "range" which is similar to r=o "ordered" but
379 does not require white-space before and after the dash in a range, e.g.
380 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
383 Fixed a few AC_TRY_LINK configure tests that did not operate properly
384 due to new GCC removing "redundant" code.
386 Added yaz-client commands scanpos and scanstep that sets preferred
387 position and step-size for scan.
389 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
391 Added CCL utility ccl_qual_buf which parses one or more CCL
392 spec lines in a buffer.
394 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
395 of name and value - ignoring empty lines and comments.
397 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
399 Added odr_get_element_path which returns current element path for an
400 ODR handle. This utility is useful in error handling or user-defined
403 Added ODR_PRINT utility odr_set_stream which is is a more generic
404 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
405 to a write function and pointer to close function. The close function - if
406 non-NULL - will be called during odr_destroy.
408 Fixed bug in CCL parser where truncation char was not removed from
409 right side when truncation=both was in effect.
411 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
414 --- 2.0.23 2004/08/11
416 Fix buffer overrun in CQL parser when dealing with proximity (%).
418 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
419 to UTF-8/UCS conversion is now only based on codetables.xml.
421 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
423 --- 2.0.22 2004/08/06
425 Add support for more "commit changes" in ZOOM (uses Extended Services).
427 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
430 Yet another small fix for configure of SSL.
432 --- 2.0.21 2004/05/14
434 Fix SSL libs for configure when --with-openssl=DIR is given.
436 --- 2.0.20 2004/05/10
438 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
440 SSL comstack now uses yaz.pem certificate file on server side
441 by default. Certificate filename can be configured by calling
442 comstack function cs_set_ssl_certificate_file before cs_bind is used.
444 Fix bug regarding multiple calls to ZOOM_connection_connect.
446 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
448 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
449 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
451 ZOOM now allows inspection of X509 peer certificate for verification.
452 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
454 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
455 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
456 as "modular" but it simplifies things.
458 Added cs_get_peer_certificate to that returns peer X509 PEM.
460 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
461 NULL if SSL is unavailable.
463 Documentation about MARC decoding tools.
465 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
467 --- 2.0.19 2004/03/30
469 Rename CHANGELOG to NEWS to follow GNU style packing.
471 Fix bug with missing initialization of member in init_diagnostics.
472 This bug affects threaded version of GFS server.
474 --- 2.0.18 2004/03/20
476 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
479 Ensure zlib.dll is packed with Windows install.
481 --- 2.0.17 2004/03/17
483 Fix encoding of xsd:string to use text instead of CDATA.
485 Fix endless loop in CQL parser with unbalanced ".
487 Use a more compact way to store MARC-8 conversion tables.
489 --- 2.0.16 2004/03/16 Debian only
491 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
494 Update CQL parser to use new CQL 1.1 modifiers for booleans and
499 --- 2.0.15 2004/03/01
501 Another fix for decoding of XML packed records.
503 --- 2.0.14 2004/02/25
505 Fixes for Chunked encoding. White space not ignored after length spec.
507 Update NS and use default NS for SRW diagnostic elements.
509 --- 2.0.13 2004/02/23
511 Implement ZOOM_resultset_cache_reset which resets record cache.
513 Implement ZOOM_resultset_sort which sorts a result set.
515 Implement chunked HTTP transfer.
517 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
519 --- 2.0.12 2004/02/16
521 Added member 'schema' to bend_explain_rr structure so that backend
522 can specify explain record identifier. Defaults to Zeerex 2.0.
524 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
526 --- 2.0.11 2004/02/16
528 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
531 Added init command for yaz-client which sends "extra" init request.
533 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
534 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
536 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
538 Make ZOOM error code for "invalid query".
540 Fixed compilation for SSL which wasn't properly enabled for all platforms.
542 --- 2.0.10 2004/02/05
544 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
547 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
549 Added option -p <file> to make Generic Frontend Server to write PID file.
551 Added option -D to put Generic Frontend Server in background on its own.
553 Make ZOOM C recognize option "password". If unset, "pass" is used
554 (for backwards compatibility).
556 Fixed a bug in Generic Frontend Server that could make it crash if a
557 client sets characterSetNegotation bit, but didn't pass negotiation stuff
560 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
561 Must be issued before open, in order to be in effect.
563 --- 2.0.9-6 2004/01/12 Debian/Windows
565 Make the SRU server more picky WRT unknown params, etc.
567 Bug fix: ZOOM scan response didn't return displayTerm - when present.
569 New YAZ client command, options, that sets Z39.50 options.
571 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
572 options from a string of tokens (one token for each option bit).
574 Update SRW diagnostic code messages.
576 --- 2.0.9-5 2004/01/07 Debian/Windows
578 Handle user defined stylesheet for SRW/SRU.
580 --- 2.0.9-4 2004/01/06 Debian/Windows
582 Fix bug in decoding of Content-Length.
584 --- 2.0.9-3 2004/01/06 Debian/Windows
586 Fix a bug with decoding of XML packed records.
588 --- 2.0.9-2 2004/01/05 Debian only
590 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
592 Fix bug in SRW/SRU diagnostics decoding.
596 Fixed bug in Generic Frontend Server which could drop records exceeding
597 preferred message size. Reported and fixed by Irina Dijour.
599 Fixed calculation of package size for structured records in Generic
600 Frontend Server. Reported and fixed by Irina Dijour.
602 Fixed namespace for SRW/SRU diagnostics.
604 Fixed SEGV in yaz-client that occured for HTTP connection errors.
608 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
609 this version is incompatible with version 1.0 and older YAZ SRW/SRU
612 CQL changes to reflect recent changes to the specification:
613 * Documentation talks about context sets instead of index sets.
614 * Documentation talks about indexes instead of qualifiers.
615 * The CQL-to-PQF transformer's configuration file now uses
616 "index.set.name = <attributes>" instead of the old form
617 "qualifier.set.name = <attributes>". (Both forms are still
618 understood but the latter is deprecated.)
619 * CQL terms with no explicit index specified are now interpreted as
620 cql.serverChoice instead of srw.serverChoice (which of course
621 behaves exactly the same.)
625 MARC conversion can now generate ISO2709 output in another
626 character set. yaz-marcdump uses this facility if you invoke it
629 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
630 functions from there can be used from C++.
634 Frontend server now transfers memory from decoded packages to stream
637 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
638 references to show up.
640 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
641 the ZOOM Abstract API. The older names for the same options are still
642 also supported for the benefit of old applications.
644 ZOOM-C supports "implementationId" and "implementationVersion" options
645 to go along with "implementationName". These allow the user code to
646 specify identification strings to be sent to servers.
647 Add OID for the new ExtLite attribute set.
649 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
650 as requested/supplid by Ere Maijala <ere@atp.fi>
652 For generic frontend server, reverse the order of
653 "toolkit-supplied / application-supplied" strings sent as implementationId,
654 Name and Version. Also, remove the spaces around the slash. This brings
655 the GFS in line with the behaviour of ZOOM-C on the client side.
657 Add function ZOOM_scanset_display_term.
659 yaz-client shows scan displayTerm if present.
661 Utility yaz-iconv is now installed by default along with the man page
664 Extend configure check for OpenSSL to use pkg-config where available (such
667 Incorporate patch by Morten Bogeskov which allows a Unix file socket
668 server to specify uid/gid/mask for socket using the format
669 unix:[user=uid,][group=gid,][umask=mask,]file=path
670 If file= is omitted the existing format is assumed, e.g.
672 in which case the mask is 0666 (rw for everybody).
674 Major restructure of YAZ source. All source in libyaz is in src directory.
675 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
676 util (utility programs such as ASN.1 compiler, yaz-marcdump).
678 Added man page for utility yaz-marcdump (used to be called marcdump).
679 yaz-marcdump is installed by 'make install'.
681 Fixed a memory leak in Generic Frontend Server that occurred when decoding
682 of incoming package failed.
684 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
686 Change prototype of odr_perror: add const to message string.
688 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
690 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
691 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
692 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
693 DNS lookup. There should not be any compatibility problems with this
694 assuming that blocking=1 or 0 is used.
696 Fix bad reference in UNIX comstack in function cs_addrstr.
698 Fix for compilation on AIX.
700 The generic front-end server (server/seshigh.c) now supports returning
701 Init diagnostics to the client in User-information-field, in
702 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
707 Allow any CQL relation (not just all,any,exact,scr).
709 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
710 that features the same UI.
712 Implemented command update0 in YAZ client which is equivalent to
713 update but uses old of Ext Update ASN.1.
715 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
716 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
717 Previously no OID was used for this info.
719 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
720 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
721 returns 'malformed search term' otherwise.
723 SortResponse member resultCount now set to NULL in sort handler of
726 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
729 Add three new utility functions for translating OIDs between various
730 formats -- symbolic name such as "Usmarc", minus-1-terminated int
731 arrays and dotted strings such as "1.2.840.10003.9.5.1":
732 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
733 char *oid_to_dotstring(const int *oid, char *oidbuf);
734 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
736 Reverted modifications for ES Update definition for z_IU0Update
737 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
738 is back to YAZ 2.0.2.
740 String value attributes for CCL parser.
742 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
743 which their FirstSearch server returns in Init responses, sometimes
744 carrying useful diagnostic information when Init fails. This has the
745 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
746 "z39.50/oclcui.asn", where its definition is somewhat different from
747 what OCLC document on their web-site, as required to interoperate with
750 Support for anonymous authentication in yaz-client. Use the command
753 * Fix the OID of the Index Data-local "admin" Extended Service from
754 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
755 the 1000, which indicates a locally-defined OID, was a mistake.
759 Fix CCL directive @case handling so that it affects string match for
760 both CCL keywords and qualifiers.
762 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
763 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
764 Decoder has been updated with ASN.1 changes as listed in
765 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
766 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
767 z_IUUpdate, remains unchanged.
769 ZOOM_record_get may now return a record in a specific character set.
770 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
771 "from" is the character set of record as returned by target. "to" is
772 the character set to be returned. If omitted, "to" is UTF-8.
774 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
776 New ODR utility, odr_getelement, which returns name of element for
777 which encoding/decoding failed.
779 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
780 in cases where a required element was omitted.
782 Bug fix: some MARC8 sequences were not converted.
784 New ZOOM option "step" which specifies number of records to be
785 retrieved in one chunk. Used in conjunction with "start" and "count".
787 SRW support for yaz-client. Use scheme http: to use it, e.g.
790 yaz-client no longer does (un)intelligent character set conversions
791 by default. Can be enabled with charset and marc_charset commands.
793 xmalloc trace fix for 64-bit systems such as DEC alpha.
795 Solaris 2.6 compile fix.
797 New function, cql_strerror() translates SRW error codes, as returned
798 by cql_transform_error(), into human-readable English strings. Used
799 in yaz-client diagnostics when appropriate.
801 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
802 converts it into a type-1 query which is sent to the server. This
803 makes CQL available for use with all Z-servers, as opposed to the tiny
804 minority that can handle CQL queries themselves.
808 New Debian package layout similar to the Redhat Package layout.
810 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
811 and search result respectively.
815 Redhat package is now several packages: libyaz (runtime libraries),
816 libyaz-devel (development and documentation, and yaz (utility programs).
817 Package spec file by Morten Bøgeskov.
819 New member 'schema' in struct bend_fetch_rr which the name of requested
820 schema (SRW/SRU) for record (or NULL if none was given). The fetch
821 handler MAY set this to reflect the schema of the returned record.
823 New member 'display_term' in struct scan_entry. GFS now sets member entries
824 and allocates scan entries to be filled by user scan handler. In previous
825 version, entries member was allocated by the scan handler. That still works,
826 but the GFS will ignore member display_term - assuming it was NOT set by
827 the handler. The fact that the GFS now allocates the entries both allows
828 for new members and makes a scan handler easier to write.
830 Fix CQL lex buffer overflow.
832 SRW/SRU recordPacking. For SRW default recordPacking is string. For
833 SRU default recordPacking is string.
835 SRU protocol support for frontend server.
837 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
839 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
841 Added scan for the ZOOM shell (zoomsh).
845 * String Identifers for Schemas (Amendment 5).
846 http://lcweb.loc.gov/z3950/agency/amend/am5.html
847 Old definition for schema
848 Odr_oid *schema; /* OPT */
853 Z_InternationalString *uri;
854 #define Z_Schema_oid 1
855 #define Z_Schema_uri 2
858 * resultCount parameter to Sort Response (Amendment 1).
859 http://lcweb.loc.gov/z3950/agency/amend/am1.html
861 Support for SRW 1.0 over HTTP. This is an optional feature and
862 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
865 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
866 on the same port. SRW SearchRetrieveRequests are mapped
867 to bend_init,bend_search,bend_fetch,bend_close.
869 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
871 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
872 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
874 ZOOM connections are SRW based if schem http is used for hostname
875 in connect, e.g. z = ZOOM_connection_new("http://myserver");
876 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
878 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
879 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
880 distance=n, order=true/false, relation=le, prox unit=word. If
881 n is omitted, distance 1 is used.
883 Fixed problem with C compiler include path in wrong order.
885 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
886 on Solaris. Patch from Ko van der Sloot.
888 New MARC decode API. All new functions operate on a yaz_marc_t
889 handle. The most important new functions are: yaz_marc_create,
890 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
891 decode and destroy respectively. Decoder can produce formats
892 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
893 include/yaz/marcdisp.h.
895 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
896 to UTF-8, UCS-32, wchar_t or Latin-1.
898 * Prototypes for yaz_iconv_-functions moved to separate header
899 include/yaz/yaz-iconv.h.
901 Make a few private functions 'static' in unix.c. This prevents
902 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
904 For ZOOM connection, the options targetImplementation{Id,Name,Version}
905 are set when Init Response is received.
907 New function ZOOM_connection_error_x similar to ZOOM_connection_error
908 but returns diagnostic set as well.
910 New function yaz_strerror which is a portable wrapper for
911 strerror/strerror_r/GetLastMessage.
913 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
914 is returned for MARC. If type is "oai", then OAI MARC is returned.
916 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
921 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
923 Fix bad race conditions on SIGTERM and terminate gracefully in
926 Move retrieval (data1) module to Zebra since nobody seems to be
929 Add GRS-1 render for ZOOM using same format as yaz-client.
933 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
935 Fix broken ESpec handling in data1 module.
937 SGML reader parses comments and makes them part of the data1 tree.
939 Added several type casts so that YAZ compiles as C++ code.
941 ZOOM didn't handle PDU encoding failures properly.
943 Added more Bib-1 diagnostics (approved extensions).
945 GNU configure: better check for iconv.
947 More portable use of accept, getpeername. Check for socklen_t. Use
948 int/size_t if socklen_t is not defined.
952 PQF parser rejects bad queries - including those with extra
953 characters in them. PQF parser used to silently ignore that.
954 Cleaner API for PQF added, which allows you to get detailed
955 error information for bad queries (see yaz/pquery.h).
957 Fixed bug in ZOOM_record_get for type "database".
959 Implemented mini iconv library supporting conversions between
960 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
962 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
966 Fixed ZOOM C record cache so that preferredRecordSyntax and
967 elementSetName is used to check for already fetched records.
971 Added three members in bend_initrequest structure to facilitate
972 character set negotiation.
974 Fixed a bug in frontend server that could cause indefinite
975 loops under rare conditions.
977 Revised character set utilities (charneg.h) so that encoding
978 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
980 For PQF, directive @term <type> sets term type for Scan/Search.
981 Here <type> is general, string, numeric, null. The term type
982 is inherited - just like @attr.
984 New call odr_set_charset that sets character set conversion for
985 international-strings on a ODR stream. Prototype is:
986 int odr_set_charset(ODR o, const char *to, const char *from);
987 The InternationalString is still represented as C string in YAZ
988 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
989 won't). On the protocol level, you can use any encoding.
991 Support for UNIX sockets in ZOOM.
993 Solaris recv sometimes returns errno == ENOENT. It is treated as
994 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
996 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
997 both client and server. Code by Morten Bøgeskov.
1001 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1002 that they can be used directly from Visual Basic. You must recompile
1003 your windows APP if you're using ZOOM.
1005 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1006 Commands "lang" and "charset" sets language and character set respectively.
1007 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1008 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1010 Attributes from multiple CCL fields may be OR'ed rather than merged
1011 using directive "@field or". Fields are still merged by default -
1012 equivalent to "@field merge".
1014 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1017 Fixed bug in zget for parameter ExtendedServicesResponse.
1021 --- 1.8.6 2002/03/25
1023 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1025 Client displays USR.1:SearchResult-1 (hits per term).
1027 Additional Search Info for search in Generic Frontend Server.
1029 Fixed CCL parsing of "field=s".
1031 WIN32 installer - using the excellent NSIS software from nullsoft.
1033 Fixed CCL parsing of "field = - <number>".
1035 Added function yaz_marc_decode that decodes MARC for line mode
1036 display or XML (similar to that used by JZKit).
1038 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1039 Z39.50. But ISO/ILL was, however.
1041 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1042 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1044 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1045 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1047 --- 1.8.5 2002/02/03
1049 New YAZ client features: Command completion and new commands:
1050 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1051 Code provided by Jacob Poulsen.
1053 New call oid_trav, that visits all registered OIDs via callback.
1055 Function ZOOM_record_get now returns const char pointer rather than
1056 void pointer. It saves a lot of type casts.
1058 For YAZ client, command "auth" now allows you to set authentication
1059 in IdPass style. It is enabled when three tokens are given - order
1060 is user, group and password.
1062 Fix memory leaks in MARC record handling for ZOOM.
1064 New option for YAZ client, -k <kilobytes> that sets
1065 maximum record size. Similar to -k option for generic frontend
1066 server and yaz-ztest.
1068 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1070 Prefix query parser reports "fail" when bad attribute set is given.
1072 Fix in MARC decoder. Proximity logging. Fix for attribute set
1073 in scan handler for server. Patches by Shigeru Ishida.
1075 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1078 Configure option --with-openssl=<dir> now works when a directory is
1079 specified. Patch provided by Morten Bøgeskov.
1081 New option for YAZ client, -u <auth>, that sets authentication.
1083 ZOOM fix: error information was sometimes "missing", since error
1084 was cleared/reset too when it shouldn't.
1086 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1088 --- 1.8.4 2002/01/04
1090 Scan for ZOOM API. New object ZOOM_scanset. New functions
1091 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1092 ZOOM_scanset_destroy.
1094 New ZOOM function, ZOOM_connection_last_event, that returns type
1095 of last event (such as "receive data", "send data", "apdu received",
1098 New ZOOM option, schema, that specifies schema for retrieval.
1100 New CCL feature. Qualifiers can be aliases for one or more
1101 other qualifiers (if more than one is given, OR is used).
1103 ZOOM uses named result sets if target supports it.
1105 Two new YAZ client commands: . (dot, which sources a script of YAZ
1106 client commands), and ! (to execute shell command.). Implemented
1109 Working on Debian packages.
1111 --- 1.8.3 2001/11/19
1113 YAZ client enables named result sets only if target supports it.
1115 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1117 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1118 with key="host" to get same result.
1120 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1121 Function Z3950_resultset_record(s) returns references to records
1122 "owned" by resultset. To become owner use Z3950_record_clone.
1124 Function z_ext_record handles Extended Services. Thanks to
1127 --- 1.8.2 2001/11/12
1129 CCL Parser fix: ignore token comma when dealing with and-lists.
1131 Documentation updates for COMSTACK.
1133 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1134 Changed prototype Z3950_records. For some functions, int parameters
1135 were changed to size_t.
1137 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1140 New MARC decode/display function, marc_display_exl, which properly rejects
1141 non-ISO2709 records. YAZ client uses it.
1143 --- 1.8.1 2001/10/29
1145 Fix bug: local attribute set wasn't set correctly in PQF strings.
1149 * Old Z39.50 codecs no longer supported.
1151 Added ZOOM C binding. See http://zoom.z3950.org/
1153 Renamed states for COMSTACKs to avoid confusion with events.
1155 Implemented cs_look and proper cs_rcvconnect.
1157 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1159 Configure detects POSIX threads on OpenBSD.
1161 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1162 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1164 When error is returned from present handler, non-surrogate diagnostic
1165 is returned in present response (and fetch handler is no longer called).
1167 * Minor adjustments to pquery parser (PQF). Token characters may be
1168 escaped by using backslash (C-style).
1170 PQF parser allows string attribute values to be specified. For @attr,
1171 non-numeric characters after the equal-sign are treated as strings
1172 (e.g. @attr 9=title).
1174 CCL trunction character may be defined (@truncation in file)
1176 * function zget_ExtendedServicesRequest sets waitAction to
1177 waitIfPossible (was wait).
1179 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1182 CCL operator names may be set in field definition files (CCL_bibset).
1183 See ccl/bib1 for an example.
1185 Fixes in ASN.1 compiler for C++ compatibility.
1187 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1188 and "op_or" to avoid conflict with C++.
1190 Fixed problem with GNU readline detection on Redhat 7.0.
1192 Added step-size for Scan backend handler.
1194 Fixed bug that made the frontend server crash when no attribute
1195 set was specified for scan.
1197 Front-end server automatically switches to original working directory
1198 when installed as an NT service. Previously -w had to be specified to
1201 Added extended attributes for retrieval module (data1), so that data1
1202 records carry d1_readXML/SGML attributes. d1_read also supports
1203 null-data rules ( <tag/>)
1205 On UNIX when POSIX threads are available, a separate library libyazthread
1206 is created. Programmers should link with that library and the yaz library
1207 when using threads. The reason for the split was that some applications
1208 on Linux, such as Apache, doesn't work well when using shared objects that
1211 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1212 (or any frontend server) in SSL mode by specifying ssl: followed by
1213 address. Only tested on UNIX.
1215 Added feature for CCL module. Virtual structure s=al or s=ol generates
1216 and-list and or-list respectively instead of phrase search.
1220 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1221 log_mask_str. This was done to avoid name conflicts with other libraries
1222 (such as other PHP extensions).
1224 Added raw OID member for preferred record syntax (request_format_raw)
1225 and returned record syntax (output_format_raw) for backend fetch method.
1227 Config file yaz-config now accepts options so that it returns specific
1228 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1230 Shared library support for UNIX using GNU libtool.
1232 * Modified backend interface. Request/Response struct's replaced by
1233 one read/write C struct. For example bend_fetchrequest and
1234 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1235 Every handler - even search has to be registered in bend_init
1236 handler. This means that the YAZ library no longer refers to
1237 external functions and it makes it possible to make the whole
1238 thing a single DLL/SO.
1240 Added Segment handler for backend server.
1242 Added Zmbol/Zebra administrative functions to YAZ client.
1244 Threaded frontend server on UNIX (when POSIX Threads are available).
1245 Starting the server with option -T enables multi-threading.
1249 Added configure option --enable-comp/disable-comp to control use
1250 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1251 located in sub directory asn.
1253 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1254 in ${exec_prefix}/bin along with the other programs yaz-client and
1257 GNU automake used to maintain makefiles.
1259 Added several OID's.
1261 Changed retrieval module so that we can load records with no abstract
1262 syntax defined. Tagpaths in these records are fully composed of string
1265 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1269 On UNIX, the generated makefile now supports a proper 'make install'.
1270 The prefix can be set via GNU configure to set the install location
1271 (default is /usr/local).
1273 * YAZ programs client and ztest were renamed to yaz-client and
1274 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1275 locations, such as /usr/bin,/usr/local/bin,etc.
1277 * YAZ Header files were moved from include to include/yaz. YAZ Header
1278 files are referred to as include <yaz/log.h> rather than <log.h>.
1279 The YAZ include path (-I ..) is therefore the same as before. Programmers
1280 should update their #include statements or use -Ipath/include/yaz
1281 instead. The main motivation for doing this change is that YAZ header files
1282 can be installed in "standard" locations /usr/include,/usr/local/include
1283 without introducing conflicts, since ALL YAZ header files are stored
1284 in subdirectory yaz (under /usr/include for example).
1286 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1287 rather than project/workspace files. We switched because project files
1288 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1291 Changed name of logging function, logf, to yaz_log, to prevent name
1292 clash with some math-log functions. The YAZ header log.h defines logf
1293 to yaz_log (#define) so there should be no incompatibilities by this
1296 Added bend_start/bend_stop handlers for server. These handler are
1297 called on start/stop of server. For windows they are called whenever
1298 a service is started/stopped.
1300 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1301 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1302 in util/yc.tcl. The auto-generated C code structures are, in a few
1303 cases, incompatible with the old decoders. There are differences in the
1304 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1305 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1306 The preprocessor variable ASN_COMPILED is defined when the compiled
1307 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1308 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1309 wish to use the old encoders/decoders you can specify --disable-yc
1312 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1313 version so that it supports both new - and old version of DB Update
1315 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1316 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1317 change. The name parameter can be set to 0 in which no name is specified
1318 for the construction. The macros odr_implicit and odr_explicit sets name
1319 parameter to zero for the construction involved. New macros
1320 odr_implicit_tag and odr_explicit_tag are similar to the others,
1321 except that a name parameter is added. For programmers' that don't use
1322 ODR they probably only need to change the call to z_APDU and z_External.
1324 Added access control facility by interfacing the TCP wrapper library.
1325 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1326 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1327 name of the daemon and enables the access control as specified in
1328 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1330 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1331 den Dool <H.M.vdnDool@kub.nl>.
1333 Added reference ID parameter to most functions in server API - refer
1334 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1336 Changed name of ccl library to libccl.a (was ccl.a).
1338 Fixed bug in decoder for Explain (Category TargetInfo).
1340 Added support for GNU readline in client. Thanks to Jacob Poulsen
1341 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1343 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1344 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1345 IMPLEMENTATION! This change was made to the development version before
1346 the ZIG decided to retract the amendment. If any users MUST be
1347 compatible with the original Update definition, PLEASE CONTACT US, and
1348 we will include a separate definition corresponding to the old Update
1349 ES. Note that because of the change to the ASN.1 of the
1350 TaskPackageRecordStructure we cannot define a single structure that
1351 will support both versions.
1353 * Added const modifier to buffer parameter for some ODR/BER encoding
1354 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1355 completeWAIS, odr_dumpBER.
1357 Fixed bug in client.c which caused a crash when a scanResponse didn't
1358 contain positionOfTerm.
1360 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1361 * will cause an error in a client if a non-YAZ target sends both a
1362 * list of Scan entries and non-surrogate diagnostics.
1364 Retrieval module enhancements. Tag sets may be typed in the reference
1365 to it. From the .abs-file the "tagset" directive takes a third optional
1366 integer type for the tag set referenced. From a .tag-file the "include"
1367 directive takes a third optional type as well. The old "type" directive
1368 in the tag set itself is still recognized but acts as the default type
1371 Backend interface change. Individual Scan terms returned from bend_scan
1372 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1373 in include/backend.h.
1375 Retrieval module enhancements. Multiple tag sets and attribute sets may
1376 be specified in abstract syntax specs. Revised the error/warning for
1377 logging messages reported by the retrieval module when reading the
1380 Object Identifier system (oid_..) changed. The API is backwards
1381 compatible but the oid-routines now allocates new OID's when needed.
1382 Raw OID's may be specified in oid_getvalbyname.
1384 YAZ now uses GNU configure to generate Makefile(s).
1386 * Minor changes in some of the member names of DeleteResultSetRequest and
1387 DeleteResultSetResponse. See include/proto.h.
1389 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1390 and added member 'languages' in TargetInfo (which was missing).
1392 Changed the way attribute sets are handled in the retrieval
1393 module. These are now cached, just like the abstract syntaxes
1396 Changed YAZ so that it links with compiled ASN.1.
1398 Added Explain-schema definitions and mapping routines. The following
1399 Explain categories have been implemented: AttributeDetails,
1400 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1402 Fixed minor bug in Windows version of Server Library.
1404 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1406 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1408 Added EXTERNAL: UNIverse Resource Report (non-standard).
1410 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1411 ENUMERATED and SET OF.
1413 * Added 'const' to some of the char pointer arguments for the
1414 functions, data1_read_node, data1_getelementbytagname,
1415 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1418 Fixed bug in data1_insert_taggeddata - the last_child member of
1419 parent wasn't initialised.
1421 * Changed data1_read_record and data1_read_node so that the supplied
1422 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1423 doesn't refer to any parts of the "SGML"-buffer.
1425 Fixed bug in server library (Windows version of statserv_remove).
1427 * Changed code so that it compiles as C++. The type definition
1428 of Odr_fun which is a member of Odr_arm was changed. The result is,
1429 that an explicit typecast is needed for the fun pointer when
1430 using Odr_arm - as in:
1431 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1433 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1435 Implemented the new structured date and time definition as approved
1436 by the ZIG. Added schemaId element to the specificTag in Espec-1
1437 (also approved at the last ZIG). Thanks to RVDM.
1439 Added some Object identifiers (RVDM).
1441 Changed the Update Extended Service (RVDM).
1443 Added command "refid" to client which specifies referenceId for
1444 the following requests.
1446 Implemented extended service handling for server. See ztest.c
1447 for an example as well as backend.h. New handlers are registerd
1448 in the Init handler.
1450 * Changed interface for sort in server.
1452 Added new members to statserv_options_block. It allows a server
1453 to read options from another source than just the command line. Thanks
1454 to Charles Woodfield.
1456 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1457 renamed to zboolean. Some C++ compilers complained about the name.
1459 Minor changes to gils.abs. Added index 's' (sort) on title
1460 and date/time-last-modified.
1462 --- 1.4pl2 1998/1/30
1464 Fixed bug in server library regarding inetd mode (-i). This bug
1465 was introduced by release 1.4.
1467 --- 1.4pl1 1998/1/29
1469 Added sort facility in client and backend server interface.
1471 Fixed problem with dependencies in Makefile(s).
1473 Fixed bugs for encoders/decoders of extended services and
1476 Implemented sub-tree feature for schemas. Sub-trees are
1477 referenced in *.abs-files. See explain.abs for an example
1478 of the use of this feature.
1480 Modified bib1.att; local attributes for ANY didn't include
1481 ANY itself (only affects use of the retrieval module).
1483 Fixed bug in plain SGML reader in function data1_read_node:
1484 tags with prefix "var" was incorrectly interpreted as variants.
1486 Added feature "sub-schemas" to enable references to - and definitions
1487 of - group of elements.
1489 * Removed member parent from type data1_element (in data1.h).
1491 Implemented function odr_nullval() that returns the value of
1494 * Removed member num_children from data1_node (in data1.h).
1496 Made NT service interface part of the server library. The
1497 function statserv_main uses the NT service when required and
1498 calls the statserv_start / statserv_close routines.
1500 Routine zget_SearchRequest and zget_PresentRequest fills
1501 resultSetName/Id member with "default" instead of "Default".
1503 Fixed memory leak in server. Request queue member wasn't freed.
1505 Fixed nmem_exit so that memory is freed.
1509 Revised the CCL parser utility to be thread safe.
1511 Added function, oid_ent_to_oid, to replace the function
1512 oid_getoidbyent, which is not thread safe.
1514 * Added nmem_init and nmem_exit to initialize and release
1515 NMEM resources. Function nmem_init should be called once in the
1516 initial thread before NMEM/ODR is used. statserv.c and client.c
1517 have been changed accordingly. The change was necessary to make
1518 NMEM thread safe. The NMEM memory pool is shared amongst threads
1519 in a process. Unix-based applications will still work fine without
1522 Added NT Services interface for the the Z39.50 (statserv) Server.
1523 Refer to the ztest.c source on the usage.
1525 Windows 95/NT port using MSVC5.0. Project files are included in the
1528 * Defined new 'global' handle for the retrieval (data1) system. The
1529 new handled, data1_handle, describes the state of the data1 system.
1530 This handle is passed as first argument to virtually all
1531 data1 related routines. The functions data1_create and data1_destroy
1532 creates and destroys a data1 handle respectively.
1534 Added ODR encode stream member to all backend request structures
1535 init, search, scan etc. This stream should be used to allocate all
1536 memory used for the response when thread safe operation is needed.
1538 Changed the comstack utility, cs_addstr, to be thread safe. The
1539 returned hostname string returned by the function is now part the
1542 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1543 function. The cs_straddr takes a COMSTACK handle as argument, so this
1544 function must be used after cs_create and before bind/connect.
1545 This function is thread safe.
1547 Moved test server to 'ztest' directory - generic server code still
1548 in 'server' directory.
1550 Made prefix query (pquery.c) utility thread safe.
1552 Added new function modifier YAZ_EXPORT to 'export' public DLL
1553 functions when using windows (see include/yconfig.h).
1555 Added definitions to the OID database (util/oid.c) (RVDM).
1557 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1559 Added call to ccl_rpn_delete in client program.
1561 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1562 release of RPN structure.
1564 Added support for C++, headers uses extern "C" for public definitions.
1565 With input from RVDM.
1567 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1568 Thanks to Ronald van der Meer (RVDM).
1570 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1572 Added support for private extensions to the OID database
1573 (oid_setprivateoids()). Thanks to RVDM.
1575 Added optional, physical ANY (key replication)
1577 Fixed null-reference problem in GRS-1 output filter.
1579 Proximity operator added to Prefix Query Format (PQF).
1581 In test client command "base" accepts multiple databases.
1583 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1587 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1589 Smallish bug-fixes in the new encoders/decoders (explain).
1591 Bug fixed in DeleteRequest.
1593 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1595 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1597 Added SOIF syntax (using private OID for now) to retrieval module and client.
1599 Added Update extended service.
1601 Added SearchResult-1 additional info structure.
1603 Added optional CCL (ISO8777) interpreter as separate module. Available
1606 --- 1.2 1996/6/10 (1st anniversary release)
1608 Added Summary record syntax. Lightly tested.
1610 Added OPAC record syntax. Untested.
1612 Added ResourceReport service encoders/decoders. Untested.
1614 Fixed bug in z_Unit - wrong tagging on unitSystem.
1616 Fixed bug in the DiagRecs decoder.
1618 Added options for max PDU size and session timeout to frontend-server.
1620 Added documentation of query-language parsers and other supporting utilities.
1622 [frontend-server] Added Attribute set to the bend_scanrequest API.
1624 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1625 surrogate diagnostics were generated.
1627 [retrieval] Allow multiple local values for attribute.
1629 [retrieval] Allow multiple attributes per element in .abs files. index type.
1631 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1633 --- 1.1pl2 1996/4/10
1635 Minor changes, mostly specific to Zebra's requirements (retrieval)
1639 Repaired bug in frontend server when running multiple listening
1640 endpoints in dynamic mode.
1642 z_External() now won't break if a known, ASN.1 value comes encapsulated
1643 in an octet-string. The value will pass through unmodified in an Odr_oct.
1645 Added a bit of code to the demo client to decode & display
1646 ASN.1-structured records represented in the octet-aligned branch of
1647 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1649 Added z_ext_getentbyref() to the ASN module. Doc updated.
1651 * Completed the SCAN definition in the ASN module. This may break SCAN
1652 code based on older YAZ-versions at compile-time. The fix is easy -
1655 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1656 under the SCAN definition. Remember to initialize this, server-people.
1658 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1659 that this does not extend to ODR and ASN.
1661 Comstack allows insertion of established socket (primarily for
1662 inetd-operation of servers). Doc updated.
1664 Front-end server can now start from the inetd in TCP mode. Doc
1667 --- 1.0pl4 1996/1/24
1671 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1672 the rank and record number.
1674 Adjustments to the frontend server.
1676 Fixed diagnostic BER dumper. It ignored the file argument.
1680 Various changes to retrieval module.
1682 Changed the union discriminators of the protocol files from enums to
1683 ints paired with #defines.
1685 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1688 *Changed operator in the RPN structure to 'roperator', again to avoid a
1691 Fixed problems in Explain decoders/encoders.
1693 --- 1.0pl2 1995/12/6
1695 Memory bug in log module fixed.
1697 --- 1.0pl1 1995/12/5
1699 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1701 Bug in Explain DatabaseInfo module fixed.
1703 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1707 The shift to v1.0 signals that we now consider the *core* functionality
1708 of YAZ reasonably stable (the core being more or less equivalent to
1709 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1710 tested (Explain not at all - though that will happen soonish).
1712 Minor changes to code to support Windows port.
1714 Various minor changes after we're getting to use GRS-1 & co. more.
1716 Added Espec-1 format.
1718 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1719 of the protocol and it cannot be selected when encoding (maps into 'string'
1720 when decoding). Needed to talk to some servers.
1722 Demo client can request simple element set names.
1724 Added Diagnostic Format encoders/decoders.
1726 Added simple Close handling to frontend server (no hooks for resource
1727 reporting yet), and demonstration client.
1729 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1731 --- 1.0b3 1995/08/24
1733 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1734 handled incorrectly when records were requested in the searchResponse. This
1735 will only affect you if you use the frontend-server.
1737 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1738 Test-client will ask for and print GRS1. Ztest will return dummy records
1741 Added Explain encoders/decoders to the service-level API. Untested.
1743 Added Extended Services: Item Order encoders and decoders to the Service-
1744 level API. Untested. We could use a recent copy of the pertinent bits
1745 of the ILL protocol to add those bits.
1747 Added diagnostic format 1 encoders/decoders to the service-level API.
1750 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1751 odr_cons.c, which causes a more correct output.
1753 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1754 was always set to 0 when no records were requested in the searchRequest.
1756 * Added better external-handling. This shouldn't harm old code that
1757 *encodes* externals. It can break code that looks for a
1758 'single-ASN1-type' representation, since those types that are known
1759 are now decoded immediately. Look at the SUTRS sample code in
1760 seshigh.c and client.c. Documentation updated.
1762 Handling of structured records in bend_fetchresponse. Length -1 marks
1763 structured record, type is deduced from format field.
1765 --- 1.0b2 1995/06/27
1766 Fairly quick maintenance release to add SUTRS support.
1768 Fixed handling of SUTRS records in the demonstration client.
1770 * Added format field to the bend_fetchrequest and bend_fetchresponce
1771 structures of the backend API (frontend server). When the record is
1772 returned, the value of the format field is mapped to an OID. The
1773 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1774 of the record. The special value VAL_NONE in the bend_request means
1775 that no specific format was requested by the client. Documentation
1776 updated accordingly. Test server (ztest) will return a fixed dummy
1777 SUTRS record if your client requests SUTRS.
1779 Documentation updated accordingly.
1781 You can now set external libraries and RANLIB support in the top-level
1785 First public release.
