1 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2 SRU URI (POST/GET). Value is _raw_ URI part, such as x-id-a=v1&x-id-b=v2 .
6 Fixed problem with SRU mode type (soap, get, post) for yaz-client
9 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
13 Fixed MARC ISO2709 encoding routines to deal with character set
16 Minor changes to GFS logging. Database included in search request log
19 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
20 cached/multiple records.
22 Shared libraries are built by default on Unix+configure.
24 Changed cql2pqf transformation to use a different evaluation order. The
25 new order is: always, relation, structure, position, truncation, index
26 and relationModifier. Old order was: always, relation, relationModifier,
27 structure, index, position, truncation. Note that the the latter ones
28 override former ones for identical attributes.. The new scheme means that
29 it is possible to override any existing attribute with a relationModifier.
30 And also that it is possible to override everything for the index rule
31 (except the ones listed in relationModifier). No order is perfect but this
32 one, we believe, covers more real cases.. The "always" should have been
33 called "default", since the attributes there can be overridden with all
36 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
37 compilation phase, but also for yaz-config --cflags output. This allows
38 us to have public headers with Libxml2 stuff in them . It should also,
39 eventually, make Libxml2 checks redundant in packages using YAZ, such
44 Changed SRU update structure bend_update_rr so that SRU diagnostics are
45 stored in uri, message and details.. Previously diagnostics were stored
46 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
47 compatibility.. but he's probably the only one affected, so.
49 Added support for CCL, compiled on the client side, in ZOOM-C. This
50 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
51 input; the resulting query objects can be used for for searching with
52 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
54 YAZ' configure searches for OpenSSL by default.
56 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
57 SL_CTX_use_certificate_file. See
58 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
59 for more info. Thanks to Ko van der Sloot.
63 Bug #600: SRU GET, POST support for yaz-client. Introduced
64 command 'sru' which selects method SOAP/GET/POST.
66 Allow missingValueAction to be specified for the sortspec string -
67 function yaz_sort_spec. By default, the missing value action is null.
68 Use ! to specify "abort". Use = followed by stringvalue to specify default
71 Ensured that Present-handler (if defined) is called in GFS before any call to
72 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
73 searchRetrieve requests.
75 Documentation for YAZ is now based on the Docbook XML/XSLT using
76 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
77 is no longer depending on jade/openjade or docbook-to-man scripts.
78 PDF is no longer part of the distribution - but can optionally be
79 made using DSSSL/jadetex or FOP.
81 Added retrieval handling support in Generic Frontend Server to support
82 conversion between MARC/XML as well as XSLTtransforms. See
83 etc/yazgfs.xml for an example.
85 Added Authentication support to Generic Frontend Server in SRU
86 mode. Authentication using HTTP Basic is supported, as is the use
87 of 'x-username' and 'x-password' parameters in the request itself.
89 Added support for a new character set MARC8s identical to MARC8 except
90 that it converts combined characters to single Unicode characters in the
91 Latin-1 range (when possible).
95 ASN.1 compiler 0.4: generates brief Doxygen file header for
96 generated .h/.c files.
98 Utility yaz_iconv now supports conversion to MARC-8.
100 New facilities for the MARC module. The reading - and writing of
101 content are separate methods for the yaz_marc_t handle. The following
102 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
103 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
104 format). Write functions have prefix yaz_marc_write_.. The existing
105 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
106 available. Removed support for OAI-MARC and simplexml (not the
107 simplexml from PHP5).
109 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
110 to be returned for this connection.
112 --- 2.1.16 2006/03/31
114 Allow multiple languages and charsets to be specified with
115 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
116 negcharset iso-8859-1,utf-8
118 Translation of proximity nodes from CQL into PQF now works.
120 Moved to automake 1.8, 1.9.
122 Added function yaz_log_set_handler which allows a log handler to be
123 installed. This handler will be called for all log messages. Output
124 to file is also produced; but that can be disabled by passing NULL
125 fname to yaz_log_init_file.
127 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
129 For SRW (including GFS), accept application/soap+xml as content-type
132 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
133 produces NO stylesheet reference even if a default stylesheet is specified
136 --- 2.1.14 2006/03/14
138 Updated Windows package to include yazd.dll + yazd.lib for the
139 Development component.
141 If the environment variable YAZ_LOG is set, then it is used as a
142 string indicating the default level of logging to use if not
143 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
144 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
145 used as before. So, for example, to omit warnings from YAZ logging,
148 cql_transform() now map structure and other attributes before indexes,
149 so that index-specific structures and other attributes can override
150 defaults. So now a combination of mapping specifications such as:
152 index.dc.date = 1=date-modified 4=5
153 does the right thing.
155 cql_transform() now also respects the "always" mapping specification,
156 which establishes an initial set of attributes to be used for all
157 terms except where overridden by more specific attributes associated
158 with the index, relation or modifier.
160 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
161 which mode to use; one of "post", "get" or "soap" (SRW, default).
163 Fixes for yaz_iconv routines: changed trie-based character set conversions
164 to use only non-negative values for bit fields due to Sun's C compiler not
165 supporting negative values.
167 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
168 sequences where not read correctly. Fix by Rustam Usmanov.
170 Updated win/makefile to use options, settings which makes things
171 compile with VS C 2005.
173 --- 2.1.12 2006/02/01
175 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
177 In ZOOM socket code, use select instead of poll on MacOSX.
179 ZOOM-C now support client-side compilation of CQL into RPN that is
180 sent to the server, enabling CQL to be used against all Z39.50
181 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
182 ZOOM_query object, and submit it using ZOOM_connection_search().
183 The CQL-to-RPN translation uses a configuration file, the name of
184 which must be specified in the Connection's "cqlfile" option.
186 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
187 function, which takes as its start-term parameter a ZOOM_query object
188 (which may have had either CQL or RPN set into it).
191 --- 2.1.10 2005/11/29
193 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
194 GFS to support this as well. Backend handler, bend_srw_update, does the
195 update work. Code contributed by Ko van der Sloot.
197 Allow retrieval of Search Result-1 information in ZOOM by the use of
198 options that are attached to a result set. ZOOM documentation updated
201 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
202 UTF-8 conversion. Patch by Raj Patel.
204 Added option -m to GFS to control formatting of timestamps in log file.
206 Added 'exit' as synonym for 'quit' in yaz-client
208 Added support for specifying SRW resultSetId + resultSetIdleTime in a
209 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
210 for the new members. Patch by Ko van der Sloot.
212 Added support for SRU POST. It is supported for content-type
213 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
215 Do not build the separate Multi-threaded (MT) library libyazthread.la.
216 Instead make the library libyaz.la multi-threaded. Threading as a whole
217 can still be disabled by configure option --disable-threads. Previosly,
218 with older GLIBCs there were problems with MT libs under Apache. This
219 has now been fixed a long time ago.
221 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
224 CQL module modified to be case insensitive for relations/indexes/operations.
226 Fixed bug in CQL transform code: incorrect value relationModifieder
229 Added 'show all' command for yaz-client which retrieves all results
232 Added new yaz-client, xmles, which takes a (private) OID and
233 a document to be sent as an extended service request.
235 Describe new yaz-client commands wait_response and set_auto_wait.
237 Increase TCP/IP listener backlog from 3 (which I am guessing was
238 copied from the SunOS manual entry way back when) so SOMAXCONN, so
239 that the socket will queue as many incoming connections as it's able
240 to handle ongoing connections. In other words, it will never now
241 refuse a connection that it would be able to handle merely because
242 it's not got around to accepting() enough of the pending connections
243 yet. This is the behaviour anyway under Linux, where the listen()
244 argument is ignored; but not under BSD and on systems such as
245 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
246 YAZ-based servers should now be uniform across operating systems in
249 yaz-marcdump uses 64-bit file access on some systems. This is enabled
250 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
251 This allows yaz-marcdump to read large MARC batches (>2 GB).
253 Modified all YAZ source files - except the source which is auto-generated
254 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
257 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
258 corresponding to the existing *_setl() function. These allow option
259 values containing arbitrary valuues.
261 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
262 ZOOM_resultset_sort() in new applications. Its behaviour is identical
263 except that it returns an indicator of whether or not the sort
264 criterion was accepted (0 for OK, -1 for invalid).
268 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
269 MARC output rather than returning "new" buffer.
271 yaz-client warns about unknown init options.
273 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
277 Added support for SRW sort in Generic Frontend Server. Patch
278 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
279 sortKeys - or NULL if none is provided.
281 Fixed bug #307: It was impossible to specify indefinite/no timeout
282 for ZOOM_event. Special timeout value -1 now means indefinite timeout
285 Added support for multiple languages and charsets to be specified in
286 ZOOM. Each charset/language is separated by a blank. If negotiation is
287 in effect in init-response, Option
288 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
289 Code based on patch by Vasiliy Osadchuk.
291 Fixed bug #306: infinite recursion that occurred when calling
292 yaz_log_level_init as the first call (before other log level or
295 Fixed bug in scan handling in front end server: if preferred-Position-In-
296 Response was non-present, a NULL pointer referece was performed.
300 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
301 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
302 now defined for all those error codes. So instead of putting 109 in
303 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
304 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
306 Modified the yaz-marcdump utility to skip garbage bytes between MARC
309 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
311 Program yaz-client now exits and produces an error message if multiple
312 Z39.50 servers are specified on the command line (none or one allowed
315 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
320 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
322 Fixed bug #272: Preserve spacing for CCL terms.
326 Added support for virtual hosts and multiple backend servers for
327 the YAZ frontend server. The configution is XML based and
328 support specificition of CQL to RPN mappings and explain information.
329 See section "Virtual Hosts" in the YAZ manual.
331 Extended OPAC display utility. OPAC display utility renders
332 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
333 to supplement yaz_marc_decode_wrbuf.
335 Fixed a bug in MARC decoder that could caused it to crash for some
336 invalid MARC records. More diagnostics and warnings where added in
337 XML output (warnings, etc are stored in comments).
339 --- 2.0.34 2005/02/08
341 Fixes for UNIX domain sockets. Bug #261.
343 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
345 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
346 Added yaz_marc_subfield_str which defines subfield lead string which is
347 used in YAZ_MARC_LINE format. Default string is blank+$. Added
348 yaz_marc_endline_str which defines end of fields string used in
349 YAZ_MARC_LINE format. Default string is newline.
351 Experimental support for MarcXChange. This format can be produced
352 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
353 http://www.bs.dk/standards/MarcXchange.xsd
355 Added yaz-client commands scansize that sets maximum number of
356 entries to be returned by scan.
358 --- 2.0.32 2005/01/11
360 Added support for SRW scan in yaz-client and Generic Frontend Server.
362 * Added whereInList member to SRW Scan Term.
364 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
366 Fixed NMEM system to return aligned blocks on the smallest boundaries
367 that are suitably aligned for all possible types on the particular
368 architecture YAZ is being built for.
370 --- 2.0.30 2005/01/04
372 Fixed numerious warnings that was issued with newer versions of GCC.
374 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
375 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
378 Make YAZ Generic Frontend Server slightly faster.
380 Enhance (and reduce) logging for Generic Frontend Server.
382 Revert YAZ log system so that it flushes every write operation
383 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
385 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
386 instead of LOG_, due to name clash with syslog(3). LOG_ are still
387 present. New applications should define YAZ_USE_NEW_LOG=1 - this
388 will effectively disable old definitions.
390 --- 2.0.28 2004/11/09
392 Added yaz_log_time_format which specifies log format using
395 Added yaz_log_module_level which returns mask for a module. Value
396 is non-zero mask a if module is enabled; zero if disabled.
398 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
399 in include/yaz/cql.h.
401 Fixed bug #176: Dont throw diagnostics on empty SRU args.
403 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
405 Fixed bug #172: RPM builds does not enable SSL.
407 Doxyfile.in part of dist. Doxyfile generated by configure.
409 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
410 are given and the corresponding component does not exist.
412 Extend CCL documentation in YAZ reference. Describe r=r.
414 --- 2.0.26 2004/10/01
416 Fixed MARC->MARCXML conversion to properly deal with
417 fields, subfields, indicators having non-ASCII characters.
419 Fixed MARC->MARCXML conversion so that ASCII control characters
420 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
423 Added YAZ GFS support for conversion from Z39.50 surrogate
424 diagnostics to SRW surrogate diagnostics.
426 Bug fix: YAZ GFS did not return schema in explainResponse.
428 --- 2.0.25 2004/09/30
430 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
431 now converts recordSchema to elementSetName as well as schema URI.
433 Fixed bug in COMSTACK that prevented HTTP request packages from being
436 --- 2.0.24 2004/09/29
438 Added CCL facility r=r "range" which is similar to r=o "ordered" but
439 does not require white-space before and after the dash in a range, e.g.
440 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
443 Fixed a few AC_TRY_LINK configure tests that did not operate properly
444 due to new GCC removing "redundant" code.
446 Added yaz-client commands scanpos and scanstep that sets preferred
447 position and step-size for scan.
449 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
451 Added CCL utility ccl_qual_buf which parses one or more CCL
452 spec lines in a buffer.
454 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
455 of name and value - ignoring empty lines and comments.
457 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
459 Added odr_get_element_path which returns current element path for an
460 ODR handle. This utility is useful in error handling or user-defined
463 Added ODR_PRINT utility odr_set_stream which is is a more generic
464 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
465 to a write function and pointer to close function. The close function - if
466 non-NULL - will be called during odr_destroy.
468 Fixed bug in CCL parser where truncation char was not removed from
469 right side when truncation=both was in effect.
471 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
474 --- 2.0.23 2004/08/11
476 Fix buffer overrun in CQL parser when dealing with proximity (%).
478 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
479 to UTF-8/UCS conversion is now only based on codetables.xml.
481 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
483 --- 2.0.22 2004/08/06
485 Add support for more "commit changes" in ZOOM (uses Extended Services).
487 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
490 Yet another small fix for configure of SSL.
492 --- 2.0.21 2004/05/14
494 Fix SSL libs for configure when --with-openssl=DIR is given.
496 --- 2.0.20 2004/05/10
498 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
500 SSL comstack now uses yaz.pem certificate file on server side
501 by default. Certificate filename can be configured by calling
502 comstack function cs_set_ssl_certificate_file before cs_bind is used.
504 Fix bug regarding multiple calls to ZOOM_connection_connect.
506 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
508 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
509 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
511 ZOOM now allows inspection of X509 peer certificate for verification.
512 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
514 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
515 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
516 as "modular" but it simplifies things.
518 Added cs_get_peer_certificate to that returns peer X509 PEM.
520 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
521 NULL if SSL is unavailable.
523 Documentation about MARC decoding tools.
525 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
527 --- 2.0.19 2004/03/30
529 Rename CHANGELOG to NEWS to follow GNU style packing.
531 Fix bug with missing initialization of member in init_diagnostics.
532 This bug affects threaded version of GFS server.
534 --- 2.0.18 2004/03/20
536 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
539 Ensure zlib.dll is packed with Windows install.
541 --- 2.0.17 2004/03/17
543 Fix encoding of xsd:string to use text instead of CDATA.
545 Fix endless loop in CQL parser with unbalanced ".
547 Use a more compact way to store MARC-8 conversion tables.
549 --- 2.0.16 2004/03/16 Debian only
551 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
554 Update CQL parser to use new CQL 1.1 modifiers for booleans and
559 --- 2.0.15 2004/03/01
561 Another fix for decoding of XML packed records.
563 --- 2.0.14 2004/02/25
565 Fixes for Chunked encoding. White space not ignored after length spec.
567 Update NS and use default NS for SRW diagnostic elements.
569 --- 2.0.13 2004/02/23
571 Implement ZOOM_resultset_cache_reset which resets record cache.
573 Implement ZOOM_resultset_sort which sorts a result set.
575 Implement chunked HTTP transfer.
577 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
579 --- 2.0.12 2004/02/16
581 Added member 'schema' to bend_explain_rr structure so that backend
582 can specify explain record identifier. Defaults to Zeerex 2.0.
584 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
586 --- 2.0.11 2004/02/16
588 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
591 Added init command for yaz-client which sends "extra" init request.
593 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
594 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
596 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
598 Make ZOOM error code for "invalid query".
600 Fixed compilation for SSL which wasn't properly enabled for all platforms.
602 --- 2.0.10 2004/02/05
604 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
607 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
609 Added option -p <file> to make Generic Frontend Server to write PID file.
611 Added option -D to put Generic Frontend Server in background on its own.
613 Make ZOOM C recognize option "password". If unset, "pass" is used
614 (for backwards compatibility).
616 Fixed a bug in Generic Frontend Server that could make it crash if a
617 client sets characterSetNegotation bit, but didn't pass negotiation stuff
620 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
621 Must be issued before open, in order to be in effect.
623 --- 2.0.9-6 2004/01/12 Debian/Windows
625 Make the SRU server more picky WRT unknown params, etc.
627 Bug fix: ZOOM scan response didn't return displayTerm - when present.
629 New YAZ client command, options, that sets Z39.50 options.
631 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
632 options from a string of tokens (one token for each option bit).
634 Update SRW diagnostic code messages.
636 --- 2.0.9-5 2004/01/07 Debian/Windows
638 Handle user defined stylesheet for SRW/SRU.
640 --- 2.0.9-4 2004/01/06 Debian/Windows
642 Fix bug in decoding of Content-Length.
644 --- 2.0.9-3 2004/01/06 Debian/Windows
646 Fix a bug with decoding of XML packed records.
648 --- 2.0.9-2 2004/01/05 Debian only
650 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
652 Fix bug in SRW/SRU diagnostics decoding.
656 Fixed bug in Generic Frontend Server which could drop records exceeding
657 preferred message size. Reported and fixed by Irina Dijour.
659 Fixed calculation of package size for structured records in Generic
660 Frontend Server. Reported and fixed by Irina Dijour.
662 Fixed namespace for SRW/SRU diagnostics.
664 Fixed SEGV in yaz-client that occured for HTTP connection errors.
668 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
669 this version is incompatible with version 1.0 and older YAZ SRW/SRU
672 CQL changes to reflect recent changes to the specification:
673 * Documentation talks about context sets instead of index sets.
674 * Documentation talks about indexes instead of qualifiers.
675 * The CQL-to-PQF transformer's configuration file now uses
676 "index.set.name = <attributes>" instead of the old form
677 "qualifier.set.name = <attributes>". (Both forms are still
678 understood but the latter is deprecated.)
679 * CQL terms with no explicit index specified are now interpreted as
680 cql.serverChoice instead of srw.serverChoice (which of course
681 behaves exactly the same.)
685 MARC conversion can now generate ISO2709 output in another
686 character set. yaz-marcdump uses this facility if you invoke it
689 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
690 functions from there can be used from C++.
694 Frontend server now transfers memory from decoded packages to stream
697 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
698 references to show up.
700 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
701 the ZOOM Abstract API. The older names for the same options are still
702 also supported for the benefit of old applications.
704 ZOOM-C supports "implementationId" and "implementationVersion" options
705 to go along with "implementationName". These allow the user code to
706 specify identification strings to be sent to servers.
707 Add OID for the new ExtLite attribute set.
709 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
710 as requested/supplid by Ere Maijala <ere@atp.fi>
712 For generic frontend server, reverse the order of
713 "toolkit-supplied / application-supplied" strings sent as implementationId,
714 Name and Version. Also, remove the spaces around the slash. This brings
715 the GFS in line with the behaviour of ZOOM-C on the client side.
717 Add function ZOOM_scanset_display_term.
719 yaz-client shows scan displayTerm if present.
721 Utility yaz-iconv is now installed by default along with the man page
724 Extend configure check for OpenSSL to use pkg-config where available (such
727 Incorporate patch by Morten Bogeskov which allows a Unix file socket
728 server to specify uid/gid/mask for socket using the format
729 unix:[user=uid,][group=gid,][umask=mask,]file=path
730 If file= is omitted the existing format is assumed, e.g.
732 in which case the mask is 0666 (rw for everybody).
734 Major restructure of YAZ source. All source in libyaz is in src directory.
735 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
736 util (utility programs such as ASN.1 compiler, yaz-marcdump).
738 Added man page for utility yaz-marcdump (used to be called marcdump).
739 yaz-marcdump is installed by 'make install'.
741 Fixed a memory leak in Generic Frontend Server that occurred when decoding
742 of incoming package failed.
744 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
746 Change prototype of odr_perror: add const to message string.
748 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
750 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
751 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
752 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
753 DNS lookup. There should not be any compatibility problems with this
754 assuming that blocking=1 or 0 is used.
756 Fix bad reference in UNIX comstack in function cs_addrstr.
758 Fix for compilation on AIX.
760 The generic front-end server (server/seshigh.c) now supports returning
761 Init diagnostics to the client in User-information-field, in
762 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
767 Allow any CQL relation (not just all,any,exact,scr).
769 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
770 that features the same UI.
772 Implemented command update0 in YAZ client which is equivalent to
773 update but uses old of Ext Update ASN.1.
775 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
776 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
777 Previously no OID was used for this info.
779 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
780 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
781 returns 'malformed search term' otherwise.
783 SortResponse member resultCount now set to NULL in sort handler of
786 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
789 Add three new utility functions for translating OIDs between various
790 formats -- symbolic name such as "Usmarc", minus-1-terminated int
791 arrays and dotted strings such as "1.2.840.10003.9.5.1":
792 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
793 char *oid_to_dotstring(const int *oid, char *oidbuf);
794 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
796 Reverted modifications for ES Update definition for z_IU0Update
797 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
798 is back to YAZ 2.0.2.
800 String value attributes for CCL parser.
802 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
803 which their FirstSearch server returns in Init responses, sometimes
804 carrying useful diagnostic information when Init fails. This has the
805 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
806 "z39.50/oclcui.asn", where its definition is somewhat different from
807 what OCLC document on their web-site, as required to interoperate with
810 Support for anonymous authentication in yaz-client. Use the command
813 * Fix the OID of the Index Data-local "admin" Extended Service from
814 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
815 the 1000, which indicates a locally-defined OID, was a mistake.
819 Fix CCL directive @case handling so that it affects string match for
820 both CCL keywords and qualifiers.
822 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
823 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
824 Decoder has been updated with ASN.1 changes as listed in
825 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
826 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
827 z_IUUpdate, remains unchanged.
829 ZOOM_record_get may now return a record in a specific character set.
830 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
831 "from" is the character set of record as returned by target. "to" is
832 the character set to be returned. If omitted, "to" is UTF-8.
834 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
836 New ODR utility, odr_getelement, which returns name of element for
837 which encoding/decoding failed.
839 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
840 in cases where a required element was omitted.
842 Bug fix: some MARC8 sequences were not converted.
844 New ZOOM option "step" which specifies number of records to be
845 retrieved in one chunk. Used in conjunction with "start" and "count".
847 SRW support for yaz-client. Use scheme http: to use it, e.g.
850 yaz-client no longer does (un)intelligent character set conversions
851 by default. Can be enabled with charset and marc_charset commands.
853 xmalloc trace fix for 64-bit systems such as DEC alpha.
855 Solaris 2.6 compile fix.
857 New function, cql_strerror() translates SRW error codes, as returned
858 by cql_transform_error(), into human-readable English strings. Used
859 in yaz-client diagnostics when appropriate.
861 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
862 converts it into a type-1 query which is sent to the server. This
863 makes CQL available for use with all Z-servers, as opposed to the tiny
864 minority that can handle CQL queries themselves.
868 New Debian package layout similar to the Redhat Package layout.
870 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
871 and search result respectively.
875 Redhat package is now several packages: libyaz (runtime libraries),
876 libyaz-devel (development and documentation, and yaz (utility programs).
877 Package spec file by Morten Bøgeskov.
879 New member 'schema' in struct bend_fetch_rr which the name of requested
880 schema (SRW/SRU) for record (or NULL if none was given). The fetch
881 handler MAY set this to reflect the schema of the returned record.
883 New member 'display_term' in struct scan_entry. GFS now sets member entries
884 and allocates scan entries to be filled by user scan handler. In previous
885 version, entries member was allocated by the scan handler. That still works,
886 but the GFS will ignore member display_term - assuming it was NOT set by
887 the handler. The fact that the GFS now allocates the entries both allows
888 for new members and makes a scan handler easier to write.
890 Fix CQL lex buffer overflow.
892 SRW/SRU recordPacking. For SRW default recordPacking is string. For
893 SRU default recordPacking is string.
895 SRU protocol support for frontend server.
897 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
899 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
901 Added scan for the ZOOM shell (zoomsh).
905 * String Identifers for Schemas (Amendment 5).
906 http://lcweb.loc.gov/z3950/agency/amend/am5.html
907 Old definition for schema
908 Odr_oid *schema; /* OPT */
913 Z_InternationalString *uri;
914 #define Z_Schema_oid 1
915 #define Z_Schema_uri 2
918 * resultCount parameter to Sort Response (Amendment 1).
919 http://lcweb.loc.gov/z3950/agency/amend/am1.html
921 Support for SRW 1.0 over HTTP. This is an optional feature and
922 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
925 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
926 on the same port. SRW SearchRetrieveRequests are mapped
927 to bend_init,bend_search,bend_fetch,bend_close.
929 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
931 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
932 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
934 ZOOM connections are SRW based if schem http is used for hostname
935 in connect, e.g. z = ZOOM_connection_new("http://myserver");
936 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
938 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
939 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
940 distance=n, order=true/false, relation=le, prox unit=word. If
941 n is omitted, distance 1 is used.
943 Fixed problem with C compiler include path in wrong order.
945 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
946 on Solaris. Patch from Ko van der Sloot.
948 New MARC decode API. All new functions operate on a yaz_marc_t
949 handle. The most important new functions are: yaz_marc_create,
950 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
951 decode and destroy respectively. Decoder can produce formats
952 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
953 include/yaz/marcdisp.h.
955 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
956 to UTF-8, UCS-32, wchar_t or Latin-1.
958 * Prototypes for yaz_iconv_-functions moved to separate header
959 include/yaz/yaz-iconv.h.
961 Make a few private functions 'static' in unix.c. This prevents
962 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
964 For ZOOM connection, the options targetImplementation{Id,Name,Version}
965 are set when Init Response is received.
967 New function ZOOM_connection_error_x similar to ZOOM_connection_error
968 but returns diagnostic set as well.
970 New function yaz_strerror which is a portable wrapper for
971 strerror/strerror_r/GetLastMessage.
973 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
974 is returned for MARC. If type is "oai", then OAI MARC is returned.
976 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
981 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
983 Fix bad race conditions on SIGTERM and terminate gracefully in
986 Move retrieval (data1) module to Zebra since nobody seems to be
989 Add GRS-1 render for ZOOM using same format as yaz-client.
993 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
995 Fix broken ESpec handling in data1 module.
997 SGML reader parses comments and makes them part of the data1 tree.
999 Added several type casts so that YAZ compiles as C++ code.
1001 ZOOM didn't handle PDU encoding failures properly.
1003 Added more Bib-1 diagnostics (approved extensions).
1005 GNU configure: better check for iconv.
1007 More portable use of accept, getpeername. Check for socklen_t. Use
1008 int/size_t if socklen_t is not defined.
1012 PQF parser rejects bad queries - including those with extra
1013 characters in them. PQF parser used to silently ignore that.
1014 Cleaner API for PQF added, which allows you to get detailed
1015 error information for bad queries (see yaz/pquery.h).
1017 Fixed bug in ZOOM_record_get for type "database".
1019 Implemented mini iconv library supporting conversions between
1020 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1022 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1024 --- 1.8.9 2002/08/20
1026 Fixed ZOOM C record cache so that preferredRecordSyntax and
1027 elementSetName is used to check for already fetched records.
1029 --- 1.8.8 2002/08/02
1031 Added three members in bend_initrequest structure to facilitate
1032 character set negotiation.
1034 Fixed a bug in frontend server that could cause indefinite
1035 loops under rare conditions.
1037 Revised character set utilities (charneg.h) so that encoding
1038 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1040 For PQF, directive @term <type> sets term type for Scan/Search.
1041 Here <type> is general, string, numeric, null. The term type
1042 is inherited - just like @attr.
1044 New call odr_set_charset that sets character set conversion for
1045 international-strings on a ODR stream. Prototype is:
1046 int odr_set_charset(ODR o, const char *to, const char *from);
1047 The InternationalString is still represented as C string in YAZ
1048 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1049 won't). On the protocol level, you can use any encoding.
1051 Support for UNIX sockets in ZOOM.
1053 Solaris recv sometimes returns errno == ENOENT. It is treated as
1054 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1056 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1057 both client and server. Code by Morten Bøgeskov.
1059 --- 1.8.7 2002/05/22
1061 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1062 that they can be used directly from Visual Basic. You must recompile
1063 your windows APP if you're using ZOOM.
1065 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1066 Commands "lang" and "charset" sets language and character set respectively.
1067 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1068 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1070 Attributes from multiple CCL fields may be OR'ed rather than merged
1071 using directive "@field or". Fields are still merged by default -
1072 equivalent to "@field merge".
1074 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1077 Fixed bug in zget for parameter ExtendedServicesResponse.
1081 --- 1.8.6 2002/03/25
1083 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1085 Client displays USR.1:SearchResult-1 (hits per term).
1087 Additional Search Info for search in Generic Frontend Server.
1089 Fixed CCL parsing of "field=s".
1091 WIN32 installer - using the excellent NSIS software from nullsoft.
1093 Fixed CCL parsing of "field = - <number>".
1095 Added function yaz_marc_decode that decodes MARC for line mode
1096 display or XML (similar to that used by JZKit).
1098 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1099 Z39.50. But ISO/ILL was, however.
1101 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1102 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1104 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1105 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1107 --- 1.8.5 2002/02/03
1109 New YAZ client features: Command completion and new commands:
1110 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1111 Code provided by Jacob Poulsen.
1113 New call oid_trav, that visits all registered OIDs via callback.
1115 Function ZOOM_record_get now returns const char pointer rather than
1116 void pointer. It saves a lot of type casts.
1118 For YAZ client, command "auth" now allows you to set authentication
1119 in IdPass style. It is enabled when three tokens are given - order
1120 is user, group and password.
1122 Fix memory leaks in MARC record handling for ZOOM.
1124 New option for YAZ client, -k <kilobytes> that sets
1125 maximum record size. Similar to -k option for generic frontend
1126 server and yaz-ztest.
1128 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1130 Prefix query parser reports "fail" when bad attribute set is given.
1132 Fix in MARC decoder. Proximity logging. Fix for attribute set
1133 in scan handler for server. Patches by Shigeru Ishida.
1135 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1138 Configure option --with-openssl=<dir> now works when a directory is
1139 specified. Patch provided by Morten Bøgeskov.
1141 New option for YAZ client, -u <auth>, that sets authentication.
1143 ZOOM fix: error information was sometimes "missing", since error
1144 was cleared/reset too when it shouldn't.
1146 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1148 --- 1.8.4 2002/01/04
1150 Scan for ZOOM API. New object ZOOM_scanset. New functions
1151 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1152 ZOOM_scanset_destroy.
1154 New ZOOM function, ZOOM_connection_last_event, that returns type
1155 of last event (such as "receive data", "send data", "apdu received",
1158 New ZOOM option, schema, that specifies schema for retrieval.
1160 New CCL feature. Qualifiers can be aliases for one or more
1161 other qualifiers (if more than one is given, OR is used).
1163 ZOOM uses named result sets if target supports it.
1165 Two new YAZ client commands: . (dot, which sources a script of YAZ
1166 client commands), and ! (to execute shell command.). Implemented
1169 Working on Debian packages.
1171 --- 1.8.3 2001/11/19
1173 YAZ client enables named result sets only if target supports it.
1175 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1177 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1178 with key="host" to get same result.
1180 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1181 Function Z3950_resultset_record(s) returns references to records
1182 "owned" by resultset. To become owner use Z3950_record_clone.
1184 Function z_ext_record handles Extended Services. Thanks to
1187 --- 1.8.2 2001/11/12
1189 CCL Parser fix: ignore token comma when dealing with and-lists.
1191 Documentation updates for COMSTACK.
1193 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1194 Changed prototype Z3950_records. For some functions, int parameters
1195 were changed to size_t.
1197 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1200 New MARC decode/display function, marc_display_exl, which properly rejects
1201 non-ISO2709 records. YAZ client uses it.
1203 --- 1.8.1 2001/10/29
1205 Fix bug: local attribute set wasn't set correctly in PQF strings.
1209 * Old Z39.50 codecs no longer supported.
1211 Added ZOOM C binding. See http://zoom.z3950.org/
1213 Renamed states for COMSTACKs to avoid confusion with events.
1215 Implemented cs_look and proper cs_rcvconnect.
1217 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1219 Configure detects POSIX threads on OpenBSD.
1221 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1222 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1224 When error is returned from present handler, non-surrogate diagnostic
1225 is returned in present response (and fetch handler is no longer called).
1227 * Minor adjustments to pquery parser (PQF). Token characters may be
1228 escaped by using backslash (C-style).
1230 PQF parser allows string attribute values to be specified. For @attr,
1231 non-numeric characters after the equal-sign are treated as strings
1232 (e.g. @attr 9=title).
1234 CCL trunction character may be defined (@truncation in file)
1236 * function zget_ExtendedServicesRequest sets waitAction to
1237 waitIfPossible (was wait).
1239 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1242 CCL operator names may be set in field definition files (CCL_bibset).
1243 See ccl/bib1 for an example.
1245 Fixes in ASN.1 compiler for C++ compatibility.
1247 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1248 and "op_or" to avoid conflict with C++.
1250 Fixed problem with GNU readline detection on Redhat 7.0.
1252 Added step-size for Scan backend handler.
1254 Fixed bug that made the frontend server crash when no attribute
1255 set was specified for scan.
1257 Front-end server automatically switches to original working directory
1258 when installed as an NT service. Previously -w had to be specified to
1261 Added extended attributes for retrieval module (data1), so that data1
1262 records carry d1_readXML/SGML attributes. d1_read also supports
1263 null-data rules ( <tag/>)
1265 On UNIX when POSIX threads are available, a separate library libyazthread
1266 is created. Programmers should link with that library and the yaz library
1267 when using threads. The reason for the split was that some applications
1268 on Linux, such as Apache, doesn't work well when using shared objects that
1271 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1272 (or any frontend server) in SSL mode by specifying ssl: followed by
1273 address. Only tested on UNIX.
1275 Added feature for CCL module. Virtual structure s=al or s=ol generates
1276 and-list and or-list respectively instead of phrase search.
1280 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1281 log_mask_str. This was done to avoid name conflicts with other libraries
1282 (such as other PHP extensions).
1284 Added raw OID member for preferred record syntax (request_format_raw)
1285 and returned record syntax (output_format_raw) for backend fetch method.
1287 Config file yaz-config now accepts options so that it returns specific
1288 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1290 Shared library support for UNIX using GNU libtool.
1292 * Modified backend interface. Request/Response struct's replaced by
1293 one read/write C struct. For example bend_fetchrequest and
1294 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1295 Every handler - even search has to be registered in bend_init
1296 handler. This means that the YAZ library no longer refers to
1297 external functions and it makes it possible to make the whole
1298 thing a single DLL/SO.
1300 Added Segment handler for backend server.
1302 Added Zmbol/Zebra administrative functions to YAZ client.
1304 Threaded frontend server on UNIX (when POSIX Threads are available).
1305 Starting the server with option -T enables multi-threading.
1309 Added configure option --enable-comp/disable-comp to control use
1310 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1311 located in sub directory asn.
1313 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1314 in ${exec_prefix}/bin along with the other programs yaz-client and
1317 GNU automake used to maintain makefiles.
1319 Added several OID's.
1321 Changed retrieval module so that we can load records with no abstract
1322 syntax defined. Tagpaths in these records are fully composed of string
1325 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1329 On UNIX, the generated makefile now supports a proper 'make install'.
1330 The prefix can be set via GNU configure to set the install location
1331 (default is /usr/local).
1333 * YAZ programs client and ztest were renamed to yaz-client and
1334 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1335 locations, such as /usr/bin,/usr/local/bin,etc.
1337 * YAZ Header files were moved from include to include/yaz. YAZ Header
1338 files are referred to as include <yaz/log.h> rather than <log.h>.
1339 The YAZ include path (-I ..) is therefore the same as before. Programmers
1340 should update their #include statements or use -Ipath/include/yaz
1341 instead. The main motivation for doing this change is that YAZ header files
1342 can be installed in "standard" locations /usr/include,/usr/local/include
1343 without introducing conflicts, since ALL YAZ header files are stored
1344 in subdirectory yaz (under /usr/include for example).
1346 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1347 rather than project/workspace files. We switched because project files
1348 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1351 Changed name of logging function, logf, to yaz_log, to prevent name
1352 clash with some math-log functions. The YAZ header log.h defines logf
1353 to yaz_log (#define) so there should be no incompatibilities by this
1356 Added bend_start/bend_stop handlers for server. These handler are
1357 called on start/stop of server. For windows they are called whenever
1358 a service is started/stopped.
1360 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1361 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1362 in util/yc.tcl. The auto-generated C code structures are, in a few
1363 cases, incompatible with the old decoders. There are differences in the
1364 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1365 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1366 The preprocessor variable ASN_COMPILED is defined when the compiled
1367 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1368 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1369 wish to use the old encoders/decoders you can specify --disable-yc
1372 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1373 version so that it supports both new - and old version of DB Update
1375 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1376 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1377 change. The name parameter can be set to 0 in which no name is specified
1378 for the construction. The macros odr_implicit and odr_explicit sets name
1379 parameter to zero for the construction involved. New macros
1380 odr_implicit_tag and odr_explicit_tag are similar to the others,
1381 except that a name parameter is added. For programmers' that don't use
1382 ODR they probably only need to change the call to z_APDU and z_External.
1384 Added access control facility by interfacing the TCP wrapper library.
1385 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1386 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1387 name of the daemon and enables the access control as specified in
1388 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1390 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1391 den Dool <H.M.vdnDool@kub.nl>.
1393 Added reference ID parameter to most functions in server API - refer
1394 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1396 Changed name of ccl library to libccl.a (was ccl.a).
1398 Fixed bug in decoder for Explain (Category TargetInfo).
1400 Added support for GNU readline in client. Thanks to Jacob Poulsen
1401 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1403 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1404 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1405 IMPLEMENTATION! This change was made to the development version before
1406 the ZIG decided to retract the amendment. If any users MUST be
1407 compatible with the original Update definition, PLEASE CONTACT US, and
1408 we will include a separate definition corresponding to the old Update
1409 ES. Note that because of the change to the ASN.1 of the
1410 TaskPackageRecordStructure we cannot define a single structure that
1411 will support both versions.
1413 * Added const modifier to buffer parameter for some ODR/BER encoding
1414 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1415 completeWAIS, odr_dumpBER.
1417 Fixed bug in client.c which caused a crash when a scanResponse didn't
1418 contain positionOfTerm.
1420 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1421 * will cause an error in a client if a non-YAZ target sends both a
1422 * list of Scan entries and non-surrogate diagnostics.
1424 Retrieval module enhancements. Tag sets may be typed in the reference
1425 to it. From the .abs-file the "tagset" directive takes a third optional
1426 integer type for the tag set referenced. From a .tag-file the "include"
1427 directive takes a third optional type as well. The old "type" directive
1428 in the tag set itself is still recognized but acts as the default type
1431 Backend interface change. Individual Scan terms returned from bend_scan
1432 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1433 in include/backend.h.
1435 Retrieval module enhancements. Multiple tag sets and attribute sets may
1436 be specified in abstract syntax specs. Revised the error/warning for
1437 logging messages reported by the retrieval module when reading the
1440 Object Identifier system (oid_..) changed. The API is backwards
1441 compatible but the oid-routines now allocates new OID's when needed.
1442 Raw OID's may be specified in oid_getvalbyname.
1444 YAZ now uses GNU configure to generate Makefile(s).
1446 * Minor changes in some of the member names of DeleteResultSetRequest and
1447 DeleteResultSetResponse. See include/proto.h.
1449 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1450 and added member 'languages' in TargetInfo (which was missing).
1452 Changed the way attribute sets are handled in the retrieval
1453 module. These are now cached, just like the abstract syntaxes
1456 Changed YAZ so that it links with compiled ASN.1.
1458 Added Explain-schema definitions and mapping routines. The following
1459 Explain categories have been implemented: AttributeDetails,
1460 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1462 Fixed minor bug in Windows version of Server Library.
1464 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1466 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1468 Added EXTERNAL: UNIverse Resource Report (non-standard).
1470 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1471 ENUMERATED and SET OF.
1473 * Added 'const' to some of the char pointer arguments for the
1474 functions, data1_read_node, data1_getelementbytagname,
1475 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1478 Fixed bug in data1_insert_taggeddata - the last_child member of
1479 parent wasn't initialised.
1481 * Changed data1_read_record and data1_read_node so that the supplied
1482 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1483 doesn't refer to any parts of the "SGML"-buffer.
1485 Fixed bug in server library (Windows version of statserv_remove).
1487 * Changed code so that it compiles as C++. The type definition
1488 of Odr_fun which is a member of Odr_arm was changed. The result is,
1489 that an explicit typecast is needed for the fun pointer when
1490 using Odr_arm - as in:
1491 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1493 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1495 Implemented the new structured date and time definition as approved
1496 by the ZIG. Added schemaId element to the specificTag in Espec-1
1497 (also approved at the last ZIG). Thanks to RVDM.
1499 Added some Object identifiers (RVDM).
1501 Changed the Update Extended Service (RVDM).
1503 Added command "refid" to client which specifies referenceId for
1504 the following requests.
1506 Implemented extended service handling for server. See ztest.c
1507 for an example as well as backend.h. New handlers are registerd
1508 in the Init handler.
1510 * Changed interface for sort in server.
1512 Added new members to statserv_options_block. It allows a server
1513 to read options from another source than just the command line. Thanks
1514 to Charles Woodfield.
1516 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1517 renamed to zboolean. Some C++ compilers complained about the name.
1519 Minor changes to gils.abs. Added index 's' (sort) on title
1520 and date/time-last-modified.
1522 --- 1.4pl2 1998/1/30
1524 Fixed bug in server library regarding inetd mode (-i). This bug
1525 was introduced by release 1.4.
1527 --- 1.4pl1 1998/1/29
1529 Added sort facility in client and backend server interface.
1531 Fixed problem with dependencies in Makefile(s).
1533 Fixed bugs for encoders/decoders of extended services and
1536 Implemented sub-tree feature for schemas. Sub-trees are
1537 referenced in *.abs-files. See explain.abs for an example
1538 of the use of this feature.
1540 Modified bib1.att; local attributes for ANY didn't include
1541 ANY itself (only affects use of the retrieval module).
1543 Fixed bug in plain SGML reader in function data1_read_node:
1544 tags with prefix "var" was incorrectly interpreted as variants.
1546 Added feature "sub-schemas" to enable references to - and definitions
1547 of - group of elements.
1549 * Removed member parent from type data1_element (in data1.h).
1551 Implemented function odr_nullval() that returns the value of
1554 * Removed member num_children from data1_node (in data1.h).
1556 Made NT service interface part of the server library. The
1557 function statserv_main uses the NT service when required and
1558 calls the statserv_start / statserv_close routines.
1560 Routine zget_SearchRequest and zget_PresentRequest fills
1561 resultSetName/Id member with "default" instead of "Default".
1563 Fixed memory leak in server. Request queue member wasn't freed.
1565 Fixed nmem_exit so that memory is freed.
1569 Revised the CCL parser utility to be thread safe.
1571 Added function, oid_ent_to_oid, to replace the function
1572 oid_getoidbyent, which is not thread safe.
1574 * Added nmem_init and nmem_exit to initialize and release
1575 NMEM resources. Function nmem_init should be called once in the
1576 initial thread before NMEM/ODR is used. statserv.c and client.c
1577 have been changed accordingly. The change was necessary to make
1578 NMEM thread safe. The NMEM memory pool is shared amongst threads
1579 in a process. Unix-based applications will still work fine without
1582 Added NT Services interface for the the Z39.50 (statserv) Server.
1583 Refer to the ztest.c source on the usage.
1585 Windows 95/NT port using MSVC5.0. Project files are included in the
1588 * Defined new 'global' handle for the retrieval (data1) system. The
1589 new handled, data1_handle, describes the state of the data1 system.
1590 This handle is passed as first argument to virtually all
1591 data1 related routines. The functions data1_create and data1_destroy
1592 creates and destroys a data1 handle respectively.
1594 Added ODR encode stream member to all backend request structures
1595 init, search, scan etc. This stream should be used to allocate all
1596 memory used for the response when thread safe operation is needed.
1598 Changed the comstack utility, cs_addstr, to be thread safe. The
1599 returned hostname string returned by the function is now part the
1602 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1603 function. The cs_straddr takes a COMSTACK handle as argument, so this
1604 function must be used after cs_create and before bind/connect.
1605 This function is thread safe.
1607 Moved test server to 'ztest' directory - generic server code still
1608 in 'server' directory.
1610 Made prefix query (pquery.c) utility thread safe.
1612 Added new function modifier YAZ_EXPORT to 'export' public DLL
1613 functions when using windows (see include/yconfig.h).
1615 Added definitions to the OID database (util/oid.c) (RVDM).
1617 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1619 Added call to ccl_rpn_delete in client program.
1621 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1622 release of RPN structure.
1624 Added support for C++, headers uses extern "C" for public definitions.
1625 With input from RVDM.
1627 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1628 Thanks to Ronald van der Meer (RVDM).
1630 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1632 Added support for private extensions to the OID database
1633 (oid_setprivateoids()). Thanks to RVDM.
1635 Added optional, physical ANY (key replication)
1637 Fixed null-reference problem in GRS-1 output filter.
1639 Proximity operator added to Prefix Query Format (PQF).
1641 In test client command "base" accepts multiple databases.
1643 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1647 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1649 Smallish bug-fixes in the new encoders/decoders (explain).
1651 Bug fixed in DeleteRequest.
1653 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1655 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1657 Added SOIF syntax (using private OID for now) to retrieval module and client.
1659 Added Update extended service.
1661 Added SearchResult-1 additional info structure.
1663 Added optional CCL (ISO8777) interpreter as separate module. Available
1666 --- 1.2 1996/6/10 (1st anniversary release)
1668 Added Summary record syntax. Lightly tested.
1670 Added OPAC record syntax. Untested.
1672 Added ResourceReport service encoders/decoders. Untested.
1674 Fixed bug in z_Unit - wrong tagging on unitSystem.
1676 Fixed bug in the DiagRecs decoder.
1678 Added options for max PDU size and session timeout to frontend-server.
1680 Added documentation of query-language parsers and other supporting utilities.
1682 [frontend-server] Added Attribute set to the bend_scanrequest API.
1684 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1685 surrogate diagnostics were generated.
1687 [retrieval] Allow multiple local values for attribute.
1689 [retrieval] Allow multiple attributes per element in .abs files. index type.
1691 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1693 --- 1.1pl2 1996/4/10
1695 Minor changes, mostly specific to Zebra's requirements (retrieval)
1699 Repaired bug in frontend server when running multiple listening
1700 endpoints in dynamic mode.
1702 z_External() now won't break if a known, ASN.1 value comes encapsulated
1703 in an octet-string. The value will pass through unmodified in an Odr_oct.
1705 Added a bit of code to the demo client to decode & display
1706 ASN.1-structured records represented in the octet-aligned branch of
1707 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1709 Added z_ext_getentbyref() to the ASN module. Doc updated.
1711 * Completed the SCAN definition in the ASN module. This may break SCAN
1712 code based on older YAZ-versions at compile-time. The fix is easy -
1715 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1716 under the SCAN definition. Remember to initialize this, server-people.
1718 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1719 that this does not extend to ODR and ASN.
1721 Comstack allows insertion of established socket (primarily for
1722 inetd-operation of servers). Doc updated.
1724 Front-end server can now start from the inetd in TCP mode. Doc
1727 --- 1.0pl4 1996/1/24
1731 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1732 the rank and record number.
1734 Adjustments to the frontend server.
1736 Fixed diagnostic BER dumper. It ignored the file argument.
1740 Various changes to retrieval module.
1742 Changed the union discriminators of the protocol files from enums to
1743 ints paired with #defines.
1745 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1748 *Changed operator in the RPN structure to 'roperator', again to avoid a
1751 Fixed problems in Explain decoders/encoders.
1753 --- 1.0pl2 1995/12/6
1755 Memory bug in log module fixed.
1757 --- 1.0pl1 1995/12/5
1759 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1761 Bug in Explain DatabaseInfo module fixed.
1763 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1767 The shift to v1.0 signals that we now consider the *core* functionality
1768 of YAZ reasonably stable (the core being more or less equivalent to
1769 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1770 tested (Explain not at all - though that will happen soonish).
1772 Minor changes to code to support Windows port.
1774 Various minor changes after we're getting to use GRS-1 & co. more.
1776 Added Espec-1 format.
1778 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1779 of the protocol and it cannot be selected when encoding (maps into 'string'
1780 when decoding). Needed to talk to some servers.
1782 Demo client can request simple element set names.
1784 Added Diagnostic Format encoders/decoders.
1786 Added simple Close handling to frontend server (no hooks for resource
1787 reporting yet), and demonstration client.
1789 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1791 --- 1.0b3 1995/08/24
1793 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1794 handled incorrectly when records were requested in the searchResponse. This
1795 will only affect you if you use the frontend-server.
1797 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1798 Test-client will ask for and print GRS1. Ztest will return dummy records
1801 Added Explain encoders/decoders to the service-level API. Untested.
1803 Added Extended Services: Item Order encoders and decoders to the Service-
1804 level API. Untested. We could use a recent copy of the pertinent bits
1805 of the ILL protocol to add those bits.
1807 Added diagnostic format 1 encoders/decoders to the service-level API.
1810 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1811 odr_cons.c, which causes a more correct output.
1813 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1814 was always set to 0 when no records were requested in the searchRequest.
1816 * Added better external-handling. This shouldn't harm old code that
1817 *encodes* externals. It can break code that looks for a
1818 'single-ASN1-type' representation, since those types that are known
1819 are now decoded immediately. Look at the SUTRS sample code in
1820 seshigh.c and client.c. Documentation updated.
1822 Handling of structured records in bend_fetchresponse. Length -1 marks
1823 structured record, type is deduced from format field.
1825 --- 1.0b2 1995/06/27
1826 Fairly quick maintenance release to add SUTRS support.
1828 Fixed handling of SUTRS records in the demonstration client.
1830 * Added format field to the bend_fetchrequest and bend_fetchresponce
1831 structures of the backend API (frontend server). When the record is
1832 returned, the value of the format field is mapped to an OID. The
1833 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1834 of the record. The special value VAL_NONE in the bend_request means
1835 that no specific format was requested by the client. Documentation
1836 updated accordingly. Test server (ztest) will return a fixed dummy
1837 SUTRS record if your client requests SUTRS.
1839 Documentation updated accordingly.
1841 You can now set external libraries and RANLIB support in the top-level
1845 First public release.
