1 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2 stored in uri, message and details.. Previously diagnostics were stored
3 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
4 compatibility.. but he's probably the only one affected, so.
6 Added support for CCL, compiled on the client side, in ZOOM-C. This
7 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
8 input; the resulting query objects can be used for for searching with
9 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
11 YAZ' configure searches for OpenSSL by default.
13 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
14 SL_CTX_use_certificate_file. See
15 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
16 for more info. Thanks to Ko van der Sloot.
20 Bug #600: SRU GET, POST support for yaz-client. Introduced
21 command 'sru' which selects method SOAP/GET/POST.
23 Allow missingValueAction to be specified for the sortspec string -
24 function yaz_sort_spec. By default, the missing value action is null.
25 Use ! to specify "abort". Use = followed by stringvalue to specify default
28 Ensured that Present-handler (if defined) is called in GFS before any call to
29 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
30 searchRetrieve requests.
32 Documentation for YAZ is now based on the Docbook XML/XSLT using
33 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
34 is no longer depending on jade/openjade or docbook-to-man scripts.
35 PDF is no longer part of the distribution - but can optionally be
36 made using DSSSL/jadetex or FOP.
38 Added retrieval handling support in Generic Frontend Server to support
39 conversion between MARC/XML as well as XSLTtransforms. See
40 etc/yazgfs.xml for an example.
42 Added Authentication support to Generic Frontend Server in SRU
43 mode. Authentication using HTTP Basic is supported, as is the use
44 of 'x-username' and 'x-password' parameters in the request itself.
46 Added support for a new character set MARC8s identical to MARC8 except
47 that it converts combined characters to single Unicode characters in the
48 Latin-1 range (when possible).
52 ASN.1 compiler 0.4: generates brief Doxygen file header for
53 generated .h/.c files.
55 Utility yaz_iconv now supports conversion to MARC-8.
57 New facilities for the MARC module. The reading - and writing of
58 content are separate methods for the yaz_marc_t handle. The following
59 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
60 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
61 format). Write functions have prefix yaz_marc_write_.. The existing
62 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
63 available. Removed support for OAI-MARC and simplexml (not the
66 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
67 to be returned for this connection.
71 Allow multiple languages and charsets to be specified with
72 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
73 negcharset iso-8859-1,utf-8
75 Translation of proximity nodes from CQL into PQF now works.
77 Moved to automake 1.8, 1.9.
79 Added function yaz_log_set_handler which allows a log handler to be
80 installed. This handler will be called for all log messages. Output
81 to file is also produced; but that can be disabled by passing NULL
82 fname to yaz_log_init_file.
84 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
86 For SRW (including GFS), accept application/soap+xml as content-type
89 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
90 produces NO stylesheet reference even if a default stylesheet is specified
95 Updated Windows package to include yazd.dll + yazd.lib for the
96 Development component.
98 If the environment variable YAZ_LOG is set, then it is used as a
99 string indicating the default level of logging to use if not
100 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
101 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
102 used as before. So, for example, to omit warnings from YAZ logging,
105 cql_transform() now map structure and other attributes before indexes,
106 so that index-specific structures and other attributes can override
107 defaults. So now a combination of mapping specifications such as:
109 index.dc.date = 1=date-modified 4=5
110 does the right thing.
112 cql_transform() now also respects the "always" mapping specification,
113 which establishes an initial set of attributes to be used for all
114 terms except where overridden by more specific attributes associated
115 with the index, relation or modifier.
117 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
118 which mode to use; one of "post", "get" or "soap" (SRW, default).
120 Fixes for yaz_iconv routines: changed trie-based character set conversions
121 to use only non-negative values for bit fields due to Sun's C compiler not
122 supporting negative values.
124 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
125 sequences where not read correctly. Fix by Rustam Usmanov.
127 Updated win/makefile to use options, settings which makes things
128 compile with VS C 2005.
130 --- 2.1.12 2006/02/01
132 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
134 In ZOOM socket code, use select instead of poll on MacOSX.
136 ZOOM-C now support client-side compilation of CQL into RPN that is
137 sent to the server, enabling CQL to be used against all Z39.50
138 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
139 ZOOM_query object, and submit it using ZOOM_connection_search().
140 The CQL-to-RPN translation uses a configuration file, the name of
141 which must be specified in the Connection's "cqlfile" option.
143 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
144 function, which takes as its start-term parameter a ZOOM_query object
145 (which may have had either CQL or RPN set into it).
148 --- 2.1.10 2005/11/29
150 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
151 GFS to support this as well. Backend handler, bend_srw_update, does the
152 update work. Code contributed by Ko van der Sloot.
154 Allow retrieval of Search Result-1 information in ZOOM by the use of
155 options that are attached to a result set. ZOOM documentation updated
158 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
159 UTF-8 conversion. Patch by Raj Patel.
161 Added option -m to GFS to control formatting of timestamps in log file.
163 Added 'exit' as synonym for 'quit' in yaz-client
165 Added support for specifying SRW resultSetId + resultSetIdleTime in a
166 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
167 for the new members. Patch by Ko van der Sloot.
169 Added support for SRU POST. It is supported for content-type
170 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
172 Do not build the separate Multi-threaded (MT) library libyazthread.la.
173 Instead make the library libyaz.la multi-threaded. Threading as a whole
174 can still be disabled by configure option --disable-threads. Previosly,
175 with older GLIBCs there were problems with MT libs under Apache. This
176 has now been fixed a long time ago.
178 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
181 CQL module modified to be case insensitive for relations/indexes/operations.
183 Fixed bug in CQL transform code: incorrect value relationModifieder
186 Added 'show all' command for yaz-client which retrieves all results
189 Added new yaz-client, xmles, which takes a (private) OID and
190 a document to be sent as an extended service request.
192 Describe new yaz-client commands wait_response and set_auto_wait.
194 Increase TCP/IP listener backlog from 3 (which I am guessing was
195 copied from the SunOS manual entry way back when) so SOMAXCONN, so
196 that the socket will queue as many incoming connections as it's able
197 to handle ongoing connections. In other words, it will never now
198 refuse a connection that it would be able to handle merely because
199 it's not got around to accepting() enough of the pending connections
200 yet. This is the behaviour anyway under Linux, where the listen()
201 argument is ignored; but not under BSD and on systems such as
202 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
203 YAZ-based servers should now be uniform across operating systems in
206 yaz-marcdump uses 64-bit file access on some systems. This is enabled
207 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
208 This allows yaz-marcdump to read large MARC batches (>2 GB).
210 Modified all YAZ source files - except the source which is auto-generated
211 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
214 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
215 corresponding to the existing *_setl() function. These allow option
216 values containing arbitrary valuues.
218 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
219 ZOOM_resultset_sort() in new applications. Its behaviour is identical
220 except that it returns an indicator of whether or not the sort
221 criterion was accepted (0 for OK, -1 for invalid).
225 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
226 MARC output rather than returning "new" buffer.
228 yaz-client warns about unknown init options.
230 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
234 Added support for SRW sort in Generic Frontend Server. Patch
235 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
236 sortKeys - or NULL if none is provided.
238 Fixed bug #307: It was impossible to specify indefinite/no timeout
239 for ZOOM_event. Special timeout value -1 now means indefinite timeout
242 Added support for multiple languages and charsets to be specified in
243 ZOOM. Each charset/language is separated by a blank. If negotiation is
244 in effect in init-response, Option
245 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
246 Code based on patch by Vasiliy Osadchuk.
248 Fixed bug #306: infinite recursion that occurred when calling
249 yaz_log_level_init as the first call (before other log level or
252 Fixed bug in scan handling in front end server: if preferred-Position-In-
253 Response was non-present, a NULL pointer referece was performed.
257 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
258 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
259 now defined for all those error codes. So instead of putting 109 in
260 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
261 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
263 Modified the yaz-marcdump utility to skip garbage bytes between MARC
266 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
268 Program yaz-client now exits and produces an error message if multiple
269 Z39.50 servers are specified on the command line (none or one allowed
272 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
277 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
279 Fixed bug #272: Preserve spacing for CCL terms.
283 Added support for virtual hosts and multiple backend servers for
284 the YAZ frontend server. The configution is XML based and
285 support specificition of CQL to RPN mappings and explain information.
286 See section "Virtual Hosts" in the YAZ manual.
288 Extended OPAC display utility. OPAC display utility renders
289 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
290 to supplement yaz_marc_decode_wrbuf.
292 Fixed a bug in MARC decoder that could caused it to crash for some
293 invalid MARC records. More diagnostics and warnings where added in
294 XML output (warnings, etc are stored in comments).
296 --- 2.0.34 2005/02/08
298 Fixes for UNIX domain sockets. Bug #261.
300 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
302 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
303 Added yaz_marc_subfield_str which defines subfield lead string which is
304 used in YAZ_MARC_LINE format. Default string is blank+$. Added
305 yaz_marc_endline_str which defines end of fields string used in
306 YAZ_MARC_LINE format. Default string is newline.
308 Experimental support for MarcXChange. This format can be produced
309 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
310 http://www.bs.dk/standards/MarcXchange.xsd
312 Added yaz-client commands scansize that sets maximum number of
313 entries to be returned by scan.
315 --- 2.0.32 2005/01/11
317 Added support for SRW scan in yaz-client and Generic Frontend Server.
319 * Added whereInList member to SRW Scan Term.
321 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
323 Fixed NMEM system to return aligned blocks on the smallest boundaries
324 that are suitably aligned for all possible types on the particular
325 architecture YAZ is being built for.
327 --- 2.0.30 2005/01/04
329 Fixed numerious warnings that was issued with newer versions of GCC.
331 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
332 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
335 Make YAZ Generic Frontend Server slightly faster.
337 Enhance (and reduce) logging for Generic Frontend Server.
339 Revert YAZ log system so that it flushes every write operation
340 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
342 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
343 instead of LOG_, due to name clash with syslog(3). LOG_ are still
344 present. New applications should define YAZ_USE_NEW_LOG=1 - this
345 will effectively disable old definitions.
347 --- 2.0.28 2004/11/09
349 Added yaz_log_time_format which specifies log format using
352 Added yaz_log_module_level which returns mask for a module. Value
353 is non-zero mask a if module is enabled; zero if disabled.
355 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
356 in include/yaz/cql.h.
358 Fixed bug #176: Dont throw diagnostics on empty SRU args.
360 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
362 Fixed bug #172: RPM builds does not enable SSL.
364 Doxyfile.in part of dist. Doxyfile generated by configure.
366 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
367 are given and the corresponding component does not exist.
369 Extend CCL documentation in YAZ reference. Describe r=r.
371 --- 2.0.26 2004/10/01
373 Fixed MARC->MARCXML conversion to properly deal with
374 fields, subfields, indicators having non-ASCII characters.
376 Fixed MARC->MARCXML conversion so that ASCII control characters
377 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
380 Added YAZ GFS support for conversion from Z39.50 surrogate
381 diagnostics to SRW surrogate diagnostics.
383 Bug fix: YAZ GFS did not return schema in explainResponse.
385 --- 2.0.25 2004/09/30
387 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
388 now converts recordSchema to elementSetName as well as schema URI.
390 Fixed bug in COMSTACK that prevented HTTP request packages from being
393 --- 2.0.24 2004/09/29
395 Added CCL facility r=r "range" which is similar to r=o "ordered" but
396 does not require white-space before and after the dash in a range, e.g.
397 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
400 Fixed a few AC_TRY_LINK configure tests that did not operate properly
401 due to new GCC removing "redundant" code.
403 Added yaz-client commands scanpos and scanstep that sets preferred
404 position and step-size for scan.
406 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
408 Added CCL utility ccl_qual_buf which parses one or more CCL
409 spec lines in a buffer.
411 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
412 of name and value - ignoring empty lines and comments.
414 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
416 Added odr_get_element_path which returns current element path for an
417 ODR handle. This utility is useful in error handling or user-defined
420 Added ODR_PRINT utility odr_set_stream which is is a more generic
421 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
422 to a write function and pointer to close function. The close function - if
423 non-NULL - will be called during odr_destroy.
425 Fixed bug in CCL parser where truncation char was not removed from
426 right side when truncation=both was in effect.
428 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
431 --- 2.0.23 2004/08/11
433 Fix buffer overrun in CQL parser when dealing with proximity (%).
435 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
436 to UTF-8/UCS conversion is now only based on codetables.xml.
438 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
440 --- 2.0.22 2004/08/06
442 Add support for more "commit changes" in ZOOM (uses Extended Services).
444 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
447 Yet another small fix for configure of SSL.
449 --- 2.0.21 2004/05/14
451 Fix SSL libs for configure when --with-openssl=DIR is given.
453 --- 2.0.20 2004/05/10
455 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
457 SSL comstack now uses yaz.pem certificate file on server side
458 by default. Certificate filename can be configured by calling
459 comstack function cs_set_ssl_certificate_file before cs_bind is used.
461 Fix bug regarding multiple calls to ZOOM_connection_connect.
463 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
465 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
466 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
468 ZOOM now allows inspection of X509 peer certificate for verification.
469 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
471 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
472 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
473 as "modular" but it simplifies things.
475 Added cs_get_peer_certificate to that returns peer X509 PEM.
477 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
478 NULL if SSL is unavailable.
480 Documentation about MARC decoding tools.
482 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
484 --- 2.0.19 2004/03/30
486 Rename CHANGELOG to NEWS to follow GNU style packing.
488 Fix bug with missing initialization of member in init_diagnostics.
489 This bug affects threaded version of GFS server.
491 --- 2.0.18 2004/03/20
493 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
496 Ensure zlib.dll is packed with Windows install.
498 --- 2.0.17 2004/03/17
500 Fix encoding of xsd:string to use text instead of CDATA.
502 Fix endless loop in CQL parser with unbalanced ".
504 Use a more compact way to store MARC-8 conversion tables.
506 --- 2.0.16 2004/03/16 Debian only
508 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
511 Update CQL parser to use new CQL 1.1 modifiers for booleans and
516 --- 2.0.15 2004/03/01
518 Another fix for decoding of XML packed records.
520 --- 2.0.14 2004/02/25
522 Fixes for Chunked encoding. White space not ignored after length spec.
524 Update NS and use default NS for SRW diagnostic elements.
526 --- 2.0.13 2004/02/23
528 Implement ZOOM_resultset_cache_reset which resets record cache.
530 Implement ZOOM_resultset_sort which sorts a result set.
532 Implement chunked HTTP transfer.
534 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
536 --- 2.0.12 2004/02/16
538 Added member 'schema' to bend_explain_rr structure so that backend
539 can specify explain record identifier. Defaults to Zeerex 2.0.
541 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
543 --- 2.0.11 2004/02/16
545 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
548 Added init command for yaz-client which sends "extra" init request.
550 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
551 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
553 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
555 Make ZOOM error code for "invalid query".
557 Fixed compilation for SSL which wasn't properly enabled for all platforms.
559 --- 2.0.10 2004/02/05
561 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
564 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
566 Added option -p <file> to make Generic Frontend Server to write PID file.
568 Added option -D to put Generic Frontend Server in background on its own.
570 Make ZOOM C recognize option "password". If unset, "pass" is used
571 (for backwards compatibility).
573 Fixed a bug in Generic Frontend Server that could make it crash if a
574 client sets characterSetNegotation bit, but didn't pass negotiation stuff
577 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
578 Must be issued before open, in order to be in effect.
580 --- 2.0.9-6 2004/01/12 Debian/Windows
582 Make the SRU server more picky WRT unknown params, etc.
584 Bug fix: ZOOM scan response didn't return displayTerm - when present.
586 New YAZ client command, options, that sets Z39.50 options.
588 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
589 options from a string of tokens (one token for each option bit).
591 Update SRW diagnostic code messages.
593 --- 2.0.9-5 2004/01/07 Debian/Windows
595 Handle user defined stylesheet for SRW/SRU.
597 --- 2.0.9-4 2004/01/06 Debian/Windows
599 Fix bug in decoding of Content-Length.
601 --- 2.0.9-3 2004/01/06 Debian/Windows
603 Fix a bug with decoding of XML packed records.
605 --- 2.0.9-2 2004/01/05 Debian only
607 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
609 Fix bug in SRW/SRU diagnostics decoding.
613 Fixed bug in Generic Frontend Server which could drop records exceeding
614 preferred message size. Reported and fixed by Irina Dijour.
616 Fixed calculation of package size for structured records in Generic
617 Frontend Server. Reported and fixed by Irina Dijour.
619 Fixed namespace for SRW/SRU diagnostics.
621 Fixed SEGV in yaz-client that occured for HTTP connection errors.
625 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
626 this version is incompatible with version 1.0 and older YAZ SRW/SRU
629 CQL changes to reflect recent changes to the specification:
630 * Documentation talks about context sets instead of index sets.
631 * Documentation talks about indexes instead of qualifiers.
632 * The CQL-to-PQF transformer's configuration file now uses
633 "index.set.name = <attributes>" instead of the old form
634 "qualifier.set.name = <attributes>". (Both forms are still
635 understood but the latter is deprecated.)
636 * CQL terms with no explicit index specified are now interpreted as
637 cql.serverChoice instead of srw.serverChoice (which of course
638 behaves exactly the same.)
642 MARC conversion can now generate ISO2709 output in another
643 character set. yaz-marcdump uses this facility if you invoke it
646 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
647 functions from there can be used from C++.
651 Frontend server now transfers memory from decoded packages to stream
654 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
655 references to show up.
657 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
658 the ZOOM Abstract API. The older names for the same options are still
659 also supported for the benefit of old applications.
661 ZOOM-C supports "implementationId" and "implementationVersion" options
662 to go along with "implementationName". These allow the user code to
663 specify identification strings to be sent to servers.
664 Add OID for the new ExtLite attribute set.
666 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
667 as requested/supplid by Ere Maijala <ere@atp.fi>
669 For generic frontend server, reverse the order of
670 "toolkit-supplied / application-supplied" strings sent as implementationId,
671 Name and Version. Also, remove the spaces around the slash. This brings
672 the GFS in line with the behaviour of ZOOM-C on the client side.
674 Add function ZOOM_scanset_display_term.
676 yaz-client shows scan displayTerm if present.
678 Utility yaz-iconv is now installed by default along with the man page
681 Extend configure check for OpenSSL to use pkg-config where available (such
684 Incorporate patch by Morten Bogeskov which allows a Unix file socket
685 server to specify uid/gid/mask for socket using the format
686 unix:[user=uid,][group=gid,][umask=mask,]file=path
687 If file= is omitted the existing format is assumed, e.g.
689 in which case the mask is 0666 (rw for everybody).
691 Major restructure of YAZ source. All source in libyaz is in src directory.
692 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
693 util (utility programs such as ASN.1 compiler, yaz-marcdump).
695 Added man page for utility yaz-marcdump (used to be called marcdump).
696 yaz-marcdump is installed by 'make install'.
698 Fixed a memory leak in Generic Frontend Server that occurred when decoding
699 of incoming package failed.
701 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
703 Change prototype of odr_perror: add const to message string.
705 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
707 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
708 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
709 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
710 DNS lookup. There should not be any compatibility problems with this
711 assuming that blocking=1 or 0 is used.
713 Fix bad reference in UNIX comstack in function cs_addrstr.
715 Fix for compilation on AIX.
717 The generic front-end server (server/seshigh.c) now supports returning
718 Init diagnostics to the client in User-information-field, in
719 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
724 Allow any CQL relation (not just all,any,exact,scr).
726 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
727 that features the same UI.
729 Implemented command update0 in YAZ client which is equivalent to
730 update but uses old of Ext Update ASN.1.
732 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
733 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
734 Previously no OID was used for this info.
736 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
737 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
738 returns 'malformed search term' otherwise.
740 SortResponse member resultCount now set to NULL in sort handler of
743 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
746 Add three new utility functions for translating OIDs between various
747 formats -- symbolic name such as "Usmarc", minus-1-terminated int
748 arrays and dotted strings such as "1.2.840.10003.9.5.1":
749 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
750 char *oid_to_dotstring(const int *oid, char *oidbuf);
751 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
753 Reverted modifications for ES Update definition for z_IU0Update
754 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
755 is back to YAZ 2.0.2.
757 String value attributes for CCL parser.
759 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
760 which their FirstSearch server returns in Init responses, sometimes
761 carrying useful diagnostic information when Init fails. This has the
762 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
763 "z39.50/oclcui.asn", where its definition is somewhat different from
764 what OCLC document on their web-site, as required to interoperate with
767 Support for anonymous authentication in yaz-client. Use the command
770 * Fix the OID of the Index Data-local "admin" Extended Service from
771 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
772 the 1000, which indicates a locally-defined OID, was a mistake.
776 Fix CCL directive @case handling so that it affects string match for
777 both CCL keywords and qualifiers.
779 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
780 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
781 Decoder has been updated with ASN.1 changes as listed in
782 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
783 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
784 z_IUUpdate, remains unchanged.
786 ZOOM_record_get may now return a record in a specific character set.
787 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
788 "from" is the character set of record as returned by target. "to" is
789 the character set to be returned. If omitted, "to" is UTF-8.
791 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
793 New ODR utility, odr_getelement, which returns name of element for
794 which encoding/decoding failed.
796 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
797 in cases where a required element was omitted.
799 Bug fix: some MARC8 sequences were not converted.
801 New ZOOM option "step" which specifies number of records to be
802 retrieved in one chunk. Used in conjunction with "start" and "count".
804 SRW support for yaz-client. Use scheme http: to use it, e.g.
807 yaz-client no longer does (un)intelligent character set conversions
808 by default. Can be enabled with charset and marc_charset commands.
810 xmalloc trace fix for 64-bit systems such as DEC alpha.
812 Solaris 2.6 compile fix.
814 New function, cql_strerror() translates SRW error codes, as returned
815 by cql_transform_error(), into human-readable English strings. Used
816 in yaz-client diagnostics when appropriate.
818 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
819 converts it into a type-1 query which is sent to the server. This
820 makes CQL available for use with all Z-servers, as opposed to the tiny
821 minority that can handle CQL queries themselves.
825 New Debian package layout similar to the Redhat Package layout.
827 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
828 and search result respectively.
832 Redhat package is now several packages: libyaz (runtime libraries),
833 libyaz-devel (development and documentation, and yaz (utility programs).
834 Package spec file by Morten Bøgeskov.
836 New member 'schema' in struct bend_fetch_rr which the name of requested
837 schema (SRW/SRU) for record (or NULL if none was given). The fetch
838 handler MAY set this to reflect the schema of the returned record.
840 New member 'display_term' in struct scan_entry. GFS now sets member entries
841 and allocates scan entries to be filled by user scan handler. In previous
842 version, entries member was allocated by the scan handler. That still works,
843 but the GFS will ignore member display_term - assuming it was NOT set by
844 the handler. The fact that the GFS now allocates the entries both allows
845 for new members and makes a scan handler easier to write.
847 Fix CQL lex buffer overflow.
849 SRW/SRU recordPacking. For SRW default recordPacking is string. For
850 SRU default recordPacking is string.
852 SRU protocol support for frontend server.
854 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
856 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
858 Added scan for the ZOOM shell (zoomsh).
862 * String Identifers for Schemas (Amendment 5).
863 http://lcweb.loc.gov/z3950/agency/amend/am5.html
864 Old definition for schema
865 Odr_oid *schema; /* OPT */
870 Z_InternationalString *uri;
871 #define Z_Schema_oid 1
872 #define Z_Schema_uri 2
875 * resultCount parameter to Sort Response (Amendment 1).
876 http://lcweb.loc.gov/z3950/agency/amend/am1.html
878 Support for SRW 1.0 over HTTP. This is an optional feature and
879 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
882 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
883 on the same port. SRW SearchRetrieveRequests are mapped
884 to bend_init,bend_search,bend_fetch,bend_close.
886 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
888 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
889 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
891 ZOOM connections are SRW based if schem http is used for hostname
892 in connect, e.g. z = ZOOM_connection_new("http://myserver");
893 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
895 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
896 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
897 distance=n, order=true/false, relation=le, prox unit=word. If
898 n is omitted, distance 1 is used.
900 Fixed problem with C compiler include path in wrong order.
902 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
903 on Solaris. Patch from Ko van der Sloot.
905 New MARC decode API. All new functions operate on a yaz_marc_t
906 handle. The most important new functions are: yaz_marc_create,
907 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
908 decode and destroy respectively. Decoder can produce formats
909 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
910 include/yaz/marcdisp.h.
912 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
913 to UTF-8, UCS-32, wchar_t or Latin-1.
915 * Prototypes for yaz_iconv_-functions moved to separate header
916 include/yaz/yaz-iconv.h.
918 Make a few private functions 'static' in unix.c. This prevents
919 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
921 For ZOOM connection, the options targetImplementation{Id,Name,Version}
922 are set when Init Response is received.
924 New function ZOOM_connection_error_x similar to ZOOM_connection_error
925 but returns diagnostic set as well.
927 New function yaz_strerror which is a portable wrapper for
928 strerror/strerror_r/GetLastMessage.
930 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
931 is returned for MARC. If type is "oai", then OAI MARC is returned.
933 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
938 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
940 Fix bad race conditions on SIGTERM and terminate gracefully in
943 Move retrieval (data1) module to Zebra since nobody seems to be
946 Add GRS-1 render for ZOOM using same format as yaz-client.
950 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
952 Fix broken ESpec handling in data1 module.
954 SGML reader parses comments and makes them part of the data1 tree.
956 Added several type casts so that YAZ compiles as C++ code.
958 ZOOM didn't handle PDU encoding failures properly.
960 Added more Bib-1 diagnostics (approved extensions).
962 GNU configure: better check for iconv.
964 More portable use of accept, getpeername. Check for socklen_t. Use
965 int/size_t if socklen_t is not defined.
969 PQF parser rejects bad queries - including those with extra
970 characters in them. PQF parser used to silently ignore that.
971 Cleaner API for PQF added, which allows you to get detailed
972 error information for bad queries (see yaz/pquery.h).
974 Fixed bug in ZOOM_record_get for type "database".
976 Implemented mini iconv library supporting conversions between
977 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
979 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
983 Fixed ZOOM C record cache so that preferredRecordSyntax and
984 elementSetName is used to check for already fetched records.
988 Added three members in bend_initrequest structure to facilitate
989 character set negotiation.
991 Fixed a bug in frontend server that could cause indefinite
992 loops under rare conditions.
994 Revised character set utilities (charneg.h) so that encoding
995 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
997 For PQF, directive @term <type> sets term type for Scan/Search.
998 Here <type> is general, string, numeric, null. The term type
999 is inherited - just like @attr.
1001 New call odr_set_charset that sets character set conversion for
1002 international-strings on a ODR stream. Prototype is:
1003 int odr_set_charset(ODR o, const char *to, const char *from);
1004 The InternationalString is still represented as C string in YAZ
1005 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1006 won't). On the protocol level, you can use any encoding.
1008 Support for UNIX sockets in ZOOM.
1010 Solaris recv sometimes returns errno == ENOENT. It is treated as
1011 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1013 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1014 both client and server. Code by Morten Bøgeskov.
1016 --- 1.8.7 2002/05/22
1018 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1019 that they can be used directly from Visual Basic. You must recompile
1020 your windows APP if you're using ZOOM.
1022 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1023 Commands "lang" and "charset" sets language and character set respectively.
1024 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1025 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1027 Attributes from multiple CCL fields may be OR'ed rather than merged
1028 using directive "@field or". Fields are still merged by default -
1029 equivalent to "@field merge".
1031 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1034 Fixed bug in zget for parameter ExtendedServicesResponse.
1038 --- 1.8.6 2002/03/25
1040 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1042 Client displays USR.1:SearchResult-1 (hits per term).
1044 Additional Search Info for search in Generic Frontend Server.
1046 Fixed CCL parsing of "field=s".
1048 WIN32 installer - using the excellent NSIS software from nullsoft.
1050 Fixed CCL parsing of "field = - <number>".
1052 Added function yaz_marc_decode that decodes MARC for line mode
1053 display or XML (similar to that used by JZKit).
1055 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1056 Z39.50. But ISO/ILL was, however.
1058 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1059 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1061 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1062 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1064 --- 1.8.5 2002/02/03
1066 New YAZ client features: Command completion and new commands:
1067 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1068 Code provided by Jacob Poulsen.
1070 New call oid_trav, that visits all registered OIDs via callback.
1072 Function ZOOM_record_get now returns const char pointer rather than
1073 void pointer. It saves a lot of type casts.
1075 For YAZ client, command "auth" now allows you to set authentication
1076 in IdPass style. It is enabled when three tokens are given - order
1077 is user, group and password.
1079 Fix memory leaks in MARC record handling for ZOOM.
1081 New option for YAZ client, -k <kilobytes> that sets
1082 maximum record size. Similar to -k option for generic frontend
1083 server and yaz-ztest.
1085 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1087 Prefix query parser reports "fail" when bad attribute set is given.
1089 Fix in MARC decoder. Proximity logging. Fix for attribute set
1090 in scan handler for server. Patches by Shigeru Ishida.
1092 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1095 Configure option --with-openssl=<dir> now works when a directory is
1096 specified. Patch provided by Morten Bøgeskov.
1098 New option for YAZ client, -u <auth>, that sets authentication.
1100 ZOOM fix: error information was sometimes "missing", since error
1101 was cleared/reset too when it shouldn't.
1103 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1105 --- 1.8.4 2002/01/04
1107 Scan for ZOOM API. New object ZOOM_scanset. New functions
1108 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1109 ZOOM_scanset_destroy.
1111 New ZOOM function, ZOOM_connection_last_event, that returns type
1112 of last event (such as "receive data", "send data", "apdu received",
1115 New ZOOM option, schema, that specifies schema for retrieval.
1117 New CCL feature. Qualifiers can be aliases for one or more
1118 other qualifiers (if more than one is given, OR is used).
1120 ZOOM uses named result sets if target supports it.
1122 Two new YAZ client commands: . (dot, which sources a script of YAZ
1123 client commands), and ! (to execute shell command.). Implemented
1126 Working on Debian packages.
1128 --- 1.8.3 2001/11/19
1130 YAZ client enables named result sets only if target supports it.
1132 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1134 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1135 with key="host" to get same result.
1137 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1138 Function Z3950_resultset_record(s) returns references to records
1139 "owned" by resultset. To become owner use Z3950_record_clone.
1141 Function z_ext_record handles Extended Services. Thanks to
1144 --- 1.8.2 2001/11/12
1146 CCL Parser fix: ignore token comma when dealing with and-lists.
1148 Documentation updates for COMSTACK.
1150 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1151 Changed prototype Z3950_records. For some functions, int parameters
1152 were changed to size_t.
1154 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1157 New MARC decode/display function, marc_display_exl, which properly rejects
1158 non-ISO2709 records. YAZ client uses it.
1160 --- 1.8.1 2001/10/29
1162 Fix bug: local attribute set wasn't set correctly in PQF strings.
1166 * Old Z39.50 codecs no longer supported.
1168 Added ZOOM C binding. See http://zoom.z3950.org/
1170 Renamed states for COMSTACKs to avoid confusion with events.
1172 Implemented cs_look and proper cs_rcvconnect.
1174 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1176 Configure detects POSIX threads on OpenBSD.
1178 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1179 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1181 When error is returned from present handler, non-surrogate diagnostic
1182 is returned in present response (and fetch handler is no longer called).
1184 * Minor adjustments to pquery parser (PQF). Token characters may be
1185 escaped by using backslash (C-style).
1187 PQF parser allows string attribute values to be specified. For @attr,
1188 non-numeric characters after the equal-sign are treated as strings
1189 (e.g. @attr 9=title).
1191 CCL trunction character may be defined (@truncation in file)
1193 * function zget_ExtendedServicesRequest sets waitAction to
1194 waitIfPossible (was wait).
1196 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1199 CCL operator names may be set in field definition files (CCL_bibset).
1200 See ccl/bib1 for an example.
1202 Fixes in ASN.1 compiler for C++ compatibility.
1204 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1205 and "op_or" to avoid conflict with C++.
1207 Fixed problem with GNU readline detection on Redhat 7.0.
1209 Added step-size for Scan backend handler.
1211 Fixed bug that made the frontend server crash when no attribute
1212 set was specified for scan.
1214 Front-end server automatically switches to original working directory
1215 when installed as an NT service. Previously -w had to be specified to
1218 Added extended attributes for retrieval module (data1), so that data1
1219 records carry d1_readXML/SGML attributes. d1_read also supports
1220 null-data rules ( <tag/>)
1222 On UNIX when POSIX threads are available, a separate library libyazthread
1223 is created. Programmers should link with that library and the yaz library
1224 when using threads. The reason for the split was that some applications
1225 on Linux, such as Apache, doesn't work well when using shared objects that
1228 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1229 (or any frontend server) in SSL mode by specifying ssl: followed by
1230 address. Only tested on UNIX.
1232 Added feature for CCL module. Virtual structure s=al or s=ol generates
1233 and-list and or-list respectively instead of phrase search.
1237 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1238 log_mask_str. This was done to avoid name conflicts with other libraries
1239 (such as other PHP extensions).
1241 Added raw OID member for preferred record syntax (request_format_raw)
1242 and returned record syntax (output_format_raw) for backend fetch method.
1244 Config file yaz-config now accepts options so that it returns specific
1245 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1247 Shared library support for UNIX using GNU libtool.
1249 * Modified backend interface. Request/Response struct's replaced by
1250 one read/write C struct. For example bend_fetchrequest and
1251 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1252 Every handler - even search has to be registered in bend_init
1253 handler. This means that the YAZ library no longer refers to
1254 external functions and it makes it possible to make the whole
1255 thing a single DLL/SO.
1257 Added Segment handler for backend server.
1259 Added Zmbol/Zebra administrative functions to YAZ client.
1261 Threaded frontend server on UNIX (when POSIX Threads are available).
1262 Starting the server with option -T enables multi-threading.
1266 Added configure option --enable-comp/disable-comp to control use
1267 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1268 located in sub directory asn.
1270 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1271 in ${exec_prefix}/bin along with the other programs yaz-client and
1274 GNU automake used to maintain makefiles.
1276 Added several OID's.
1278 Changed retrieval module so that we can load records with no abstract
1279 syntax defined. Tagpaths in these records are fully composed of string
1282 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1286 On UNIX, the generated makefile now supports a proper 'make install'.
1287 The prefix can be set via GNU configure to set the install location
1288 (default is /usr/local).
1290 * YAZ programs client and ztest were renamed to yaz-client and
1291 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1292 locations, such as /usr/bin,/usr/local/bin,etc.
1294 * YAZ Header files were moved from include to include/yaz. YAZ Header
1295 files are referred to as include <yaz/log.h> rather than <log.h>.
1296 The YAZ include path (-I ..) is therefore the same as before. Programmers
1297 should update their #include statements or use -Ipath/include/yaz
1298 instead. The main motivation for doing this change is that YAZ header files
1299 can be installed in "standard" locations /usr/include,/usr/local/include
1300 without introducing conflicts, since ALL YAZ header files are stored
1301 in subdirectory yaz (under /usr/include for example).
1303 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1304 rather than project/workspace files. We switched because project files
1305 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1308 Changed name of logging function, logf, to yaz_log, to prevent name
1309 clash with some math-log functions. The YAZ header log.h defines logf
1310 to yaz_log (#define) so there should be no incompatibilities by this
1313 Added bend_start/bend_stop handlers for server. These handler are
1314 called on start/stop of server. For windows they are called whenever
1315 a service is started/stopped.
1317 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1318 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1319 in util/yc.tcl. The auto-generated C code structures are, in a few
1320 cases, incompatible with the old decoders. There are differences in the
1321 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1322 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1323 The preprocessor variable ASN_COMPILED is defined when the compiled
1324 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1325 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1326 wish to use the old encoders/decoders you can specify --disable-yc
1329 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1330 version so that it supports both new - and old version of DB Update
1332 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1333 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1334 change. The name parameter can be set to 0 in which no name is specified
1335 for the construction. The macros odr_implicit and odr_explicit sets name
1336 parameter to zero for the construction involved. New macros
1337 odr_implicit_tag and odr_explicit_tag are similar to the others,
1338 except that a name parameter is added. For programmers' that don't use
1339 ODR they probably only need to change the call to z_APDU and z_External.
1341 Added access control facility by interfacing the TCP wrapper library.
1342 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1343 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1344 name of the daemon and enables the access control as specified in
1345 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1347 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1348 den Dool <H.M.vdnDool@kub.nl>.
1350 Added reference ID parameter to most functions in server API - refer
1351 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1353 Changed name of ccl library to libccl.a (was ccl.a).
1355 Fixed bug in decoder for Explain (Category TargetInfo).
1357 Added support for GNU readline in client. Thanks to Jacob Poulsen
1358 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1360 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1361 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1362 IMPLEMENTATION! This change was made to the development version before
1363 the ZIG decided to retract the amendment. If any users MUST be
1364 compatible with the original Update definition, PLEASE CONTACT US, and
1365 we will include a separate definition corresponding to the old Update
1366 ES. Note that because of the change to the ASN.1 of the
1367 TaskPackageRecordStructure we cannot define a single structure that
1368 will support both versions.
1370 * Added const modifier to buffer parameter for some ODR/BER encoding
1371 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1372 completeWAIS, odr_dumpBER.
1374 Fixed bug in client.c which caused a crash when a scanResponse didn't
1375 contain positionOfTerm.
1377 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1378 * will cause an error in a client if a non-YAZ target sends both a
1379 * list of Scan entries and non-surrogate diagnostics.
1381 Retrieval module enhancements. Tag sets may be typed in the reference
1382 to it. From the .abs-file the "tagset" directive takes a third optional
1383 integer type for the tag set referenced. From a .tag-file the "include"
1384 directive takes a third optional type as well. The old "type" directive
1385 in the tag set itself is still recognized but acts as the default type
1388 Backend interface change. Individual Scan terms returned from bend_scan
1389 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1390 in include/backend.h.
1392 Retrieval module enhancements. Multiple tag sets and attribute sets may
1393 be specified in abstract syntax specs. Revised the error/warning for
1394 logging messages reported by the retrieval module when reading the
1397 Object Identifier system (oid_..) changed. The API is backwards
1398 compatible but the oid-routines now allocates new OID's when needed.
1399 Raw OID's may be specified in oid_getvalbyname.
1401 YAZ now uses GNU configure to generate Makefile(s).
1403 * Minor changes in some of the member names of DeleteResultSetRequest and
1404 DeleteResultSetResponse. See include/proto.h.
1406 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1407 and added member 'languages' in TargetInfo (which was missing).
1409 Changed the way attribute sets are handled in the retrieval
1410 module. These are now cached, just like the abstract syntaxes
1413 Changed YAZ so that it links with compiled ASN.1.
1415 Added Explain-schema definitions and mapping routines. The following
1416 Explain categories have been implemented: AttributeDetails,
1417 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1419 Fixed minor bug in Windows version of Server Library.
1421 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1423 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1425 Added EXTERNAL: UNIverse Resource Report (non-standard).
1427 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1428 ENUMERATED and SET OF.
1430 * Added 'const' to some of the char pointer arguments for the
1431 functions, data1_read_node, data1_getelementbytagname,
1432 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1435 Fixed bug in data1_insert_taggeddata - the last_child member of
1436 parent wasn't initialised.
1438 * Changed data1_read_record and data1_read_node so that the supplied
1439 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1440 doesn't refer to any parts of the "SGML"-buffer.
1442 Fixed bug in server library (Windows version of statserv_remove).
1444 * Changed code so that it compiles as C++. The type definition
1445 of Odr_fun which is a member of Odr_arm was changed. The result is,
1446 that an explicit typecast is needed for the fun pointer when
1447 using Odr_arm - as in:
1448 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1450 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1452 Implemented the new structured date and time definition as approved
1453 by the ZIG. Added schemaId element to the specificTag in Espec-1
1454 (also approved at the last ZIG). Thanks to RVDM.
1456 Added some Object identifiers (RVDM).
1458 Changed the Update Extended Service (RVDM).
1460 Added command "refid" to client which specifies referenceId for
1461 the following requests.
1463 Implemented extended service handling for server. See ztest.c
1464 for an example as well as backend.h. New handlers are registerd
1465 in the Init handler.
1467 * Changed interface for sort in server.
1469 Added new members to statserv_options_block. It allows a server
1470 to read options from another source than just the command line. Thanks
1471 to Charles Woodfield.
1473 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1474 renamed to zboolean. Some C++ compilers complained about the name.
1476 Minor changes to gils.abs. Added index 's' (sort) on title
1477 and date/time-last-modified.
1479 --- 1.4pl2 1998/1/30
1481 Fixed bug in server library regarding inetd mode (-i). This bug
1482 was introduced by release 1.4.
1484 --- 1.4pl1 1998/1/29
1486 Added sort facility in client and backend server interface.
1488 Fixed problem with dependencies in Makefile(s).
1490 Fixed bugs for encoders/decoders of extended services and
1493 Implemented sub-tree feature for schemas. Sub-trees are
1494 referenced in *.abs-files. See explain.abs for an example
1495 of the use of this feature.
1497 Modified bib1.att; local attributes for ANY didn't include
1498 ANY itself (only affects use of the retrieval module).
1500 Fixed bug in plain SGML reader in function data1_read_node:
1501 tags with prefix "var" was incorrectly interpreted as variants.
1503 Added feature "sub-schemas" to enable references to - and definitions
1504 of - group of elements.
1506 * Removed member parent from type data1_element (in data1.h).
1508 Implemented function odr_nullval() that returns the value of
1511 * Removed member num_children from data1_node (in data1.h).
1513 Made NT service interface part of the server library. The
1514 function statserv_main uses the NT service when required and
1515 calls the statserv_start / statserv_close routines.
1517 Routine zget_SearchRequest and zget_PresentRequest fills
1518 resultSetName/Id member with "default" instead of "Default".
1520 Fixed memory leak in server. Request queue member wasn't freed.
1522 Fixed nmem_exit so that memory is freed.
1526 Revised the CCL parser utility to be thread safe.
1528 Added function, oid_ent_to_oid, to replace the function
1529 oid_getoidbyent, which is not thread safe.
1531 * Added nmem_init and nmem_exit to initialize and release
1532 NMEM resources. Function nmem_init should be called once in the
1533 initial thread before NMEM/ODR is used. statserv.c and client.c
1534 have been changed accordingly. The change was necessary to make
1535 NMEM thread safe. The NMEM memory pool is shared amongst threads
1536 in a process. Unix-based applications will still work fine without
1539 Added NT Services interface for the the Z39.50 (statserv) Server.
1540 Refer to the ztest.c source on the usage.
1542 Windows 95/NT port using MSVC5.0. Project files are included in the
1545 * Defined new 'global' handle for the retrieval (data1) system. The
1546 new handled, data1_handle, describes the state of the data1 system.
1547 This handle is passed as first argument to virtually all
1548 data1 related routines. The functions data1_create and data1_destroy
1549 creates and destroys a data1 handle respectively.
1551 Added ODR encode stream member to all backend request structures
1552 init, search, scan etc. This stream should be used to allocate all
1553 memory used for the response when thread safe operation is needed.
1555 Changed the comstack utility, cs_addstr, to be thread safe. The
1556 returned hostname string returned by the function is now part the
1559 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1560 function. The cs_straddr takes a COMSTACK handle as argument, so this
1561 function must be used after cs_create and before bind/connect.
1562 This function is thread safe.
1564 Moved test server to 'ztest' directory - generic server code still
1565 in 'server' directory.
1567 Made prefix query (pquery.c) utility thread safe.
1569 Added new function modifier YAZ_EXPORT to 'export' public DLL
1570 functions when using windows (see include/yconfig.h).
1572 Added definitions to the OID database (util/oid.c) (RVDM).
1574 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1576 Added call to ccl_rpn_delete in client program.
1578 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1579 release of RPN structure.
1581 Added support for C++, headers uses extern "C" for public definitions.
1582 With input from RVDM.
1584 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1585 Thanks to Ronald van der Meer (RVDM).
1587 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1589 Added support for private extensions to the OID database
1590 (oid_setprivateoids()). Thanks to RVDM.
1592 Added optional, physical ANY (key replication)
1594 Fixed null-reference problem in GRS-1 output filter.
1596 Proximity operator added to Prefix Query Format (PQF).
1598 In test client command "base" accepts multiple databases.
1600 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1604 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1606 Smallish bug-fixes in the new encoders/decoders (explain).
1608 Bug fixed in DeleteRequest.
1610 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1612 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1614 Added SOIF syntax (using private OID for now) to retrieval module and client.
1616 Added Update extended service.
1618 Added SearchResult-1 additional info structure.
1620 Added optional CCL (ISO8777) interpreter as separate module. Available
1623 --- 1.2 1996/6/10 (1st anniversary release)
1625 Added Summary record syntax. Lightly tested.
1627 Added OPAC record syntax. Untested.
1629 Added ResourceReport service encoders/decoders. Untested.
1631 Fixed bug in z_Unit - wrong tagging on unitSystem.
1633 Fixed bug in the DiagRecs decoder.
1635 Added options for max PDU size and session timeout to frontend-server.
1637 Added documentation of query-language parsers and other supporting utilities.
1639 [frontend-server] Added Attribute set to the bend_scanrequest API.
1641 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1642 surrogate diagnostics were generated.
1644 [retrieval] Allow multiple local values for attribute.
1646 [retrieval] Allow multiple attributes per element in .abs files. index type.
1648 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1650 --- 1.1pl2 1996/4/10
1652 Minor changes, mostly specific to Zebra's requirements (retrieval)
1656 Repaired bug in frontend server when running multiple listening
1657 endpoints in dynamic mode.
1659 z_External() now won't break if a known, ASN.1 value comes encapsulated
1660 in an octet-string. The value will pass through unmodified in an Odr_oct.
1662 Added a bit of code to the demo client to decode & display
1663 ASN.1-structured records represented in the octet-aligned branch of
1664 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1666 Added z_ext_getentbyref() to the ASN module. Doc updated.
1668 * Completed the SCAN definition in the ASN module. This may break SCAN
1669 code based on older YAZ-versions at compile-time. The fix is easy -
1672 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1673 under the SCAN definition. Remember to initialize this, server-people.
1675 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1676 that this does not extend to ODR and ASN.
1678 Comstack allows insertion of established socket (primarily for
1679 inetd-operation of servers). Doc updated.
1681 Front-end server can now start from the inetd in TCP mode. Doc
1684 --- 1.0pl4 1996/1/24
1688 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1689 the rank and record number.
1691 Adjustments to the frontend server.
1693 Fixed diagnostic BER dumper. It ignored the file argument.
1697 Various changes to retrieval module.
1699 Changed the union discriminators of the protocol files from enums to
1700 ints paired with #defines.
1702 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1705 *Changed operator in the RPN structure to 'roperator', again to avoid a
1708 Fixed problems in Explain decoders/encoders.
1710 --- 1.0pl2 1995/12/6
1712 Memory bug in log module fixed.
1714 --- 1.0pl1 1995/12/5
1716 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1718 Bug in Explain DatabaseInfo module fixed.
1720 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1724 The shift to v1.0 signals that we now consider the *core* functionality
1725 of YAZ reasonably stable (the core being more or less equivalent to
1726 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1727 tested (Explain not at all - though that will happen soonish).
1729 Minor changes to code to support Windows port.
1731 Various minor changes after we're getting to use GRS-1 & co. more.
1733 Added Espec-1 format.
1735 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1736 of the protocol and it cannot be selected when encoding (maps into 'string'
1737 when decoding). Needed to talk to some servers.
1739 Demo client can request simple element set names.
1741 Added Diagnostic Format encoders/decoders.
1743 Added simple Close handling to frontend server (no hooks for resource
1744 reporting yet), and demonstration client.
1746 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1748 --- 1.0b3 1995/08/24
1750 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1751 handled incorrectly when records were requested in the searchResponse. This
1752 will only affect you if you use the frontend-server.
1754 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1755 Test-client will ask for and print GRS1. Ztest will return dummy records
1758 Added Explain encoders/decoders to the service-level API. Untested.
1760 Added Extended Services: Item Order encoders and decoders to the Service-
1761 level API. Untested. We could use a recent copy of the pertinent bits
1762 of the ILL protocol to add those bits.
1764 Added diagnostic format 1 encoders/decoders to the service-level API.
1767 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1768 odr_cons.c, which causes a more correct output.
1770 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1771 was always set to 0 when no records were requested in the searchRequest.
1773 * Added better external-handling. This shouldn't harm old code that
1774 *encodes* externals. It can break code that looks for a
1775 'single-ASN1-type' representation, since those types that are known
1776 are now decoded immediately. Look at the SUTRS sample code in
1777 seshigh.c and client.c. Documentation updated.
1779 Handling of structured records in bend_fetchresponse. Length -1 marks
1780 structured record, type is deduced from format field.
1782 --- 1.0b2 1995/06/27
1783 Fairly quick maintenance release to add SUTRS support.
1785 Fixed handling of SUTRS records in the demonstration client.
1787 * Added format field to the bend_fetchrequest and bend_fetchresponce
1788 structures of the backend API (frontend server). When the record is
1789 returned, the value of the format field is mapped to an OID. The
1790 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1791 of the record. The special value VAL_NONE in the bend_request means
1792 that no specific format was requested by the client. Documentation
1793 updated accordingly. Test server (ztest) will return a fixed dummy
1794 SUTRS record if your client requests SUTRS.
1796 Documentation updated accordingly.
1798 You can now set external libraries and RANLIB support in the top-level
1802 First public release.
