2 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
6 Fixed MARC ISO2709 encoding routines to deal with character set
9 Minor changes to GFS logging. Database included in search request log
12 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
13 cached/multiple records.
15 Shared libraries are built by default on Unix+configure.
17 Changed cql2pqf transformation to use a different evaluation order. The
18 new order is: always, relation, structure, position, truncation, index
19 and relationModifier. Old order was: always, relation, relationModifier,
20 structure, index, position, truncation. Note that the the latter ones
21 override former ones for identical attributes.. The new scheme means that
22 it is possible to override any existing attribute with a relationModifier.
23 And also that it is possible to override everything for the index rule
24 (except the ones listed in relationModifier). No order is perfect but this
25 one, we believe, covers more real cases.. The "always" should have been
26 called "default", since the attributes there can be overridden with all
29 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
30 compilation phase, but also for yaz-config --cflags output. This allows
31 us to have public headers with Libxml2 stuff in them . It should also,
32 eventually, make Libxml2 checks redundant in packages using YAZ, such
37 Changed SRU update structure bend_update_rr so that SRU diagnostics are
38 stored in uri, message and details.. Previously diagnostics were stored
39 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
40 compatibility.. but he's probably the only one affected, so.
42 Added support for CCL, compiled on the client side, in ZOOM-C. This
43 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
44 input; the resulting query objects can be used for for searching with
45 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
47 YAZ' configure searches for OpenSSL by default.
49 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
50 SL_CTX_use_certificate_file. See
51 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
52 for more info. Thanks to Ko van der Sloot.
56 Bug #600: SRU GET, POST support for yaz-client. Introduced
57 command 'sru' which selects method SOAP/GET/POST.
59 Allow missingValueAction to be specified for the sortspec string -
60 function yaz_sort_spec. By default, the missing value action is null.
61 Use ! to specify "abort". Use = followed by stringvalue to specify default
64 Ensured that Present-handler (if defined) is called in GFS before any call to
65 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
66 searchRetrieve requests.
68 Documentation for YAZ is now based on the Docbook XML/XSLT using
69 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
70 is no longer depending on jade/openjade or docbook-to-man scripts.
71 PDF is no longer part of the distribution - but can optionally be
72 made using DSSSL/jadetex or FOP.
74 Added retrieval handling support in Generic Frontend Server to support
75 conversion between MARC/XML as well as XSLTtransforms. See
76 etc/yazgfs.xml for an example.
78 Added Authentication support to Generic Frontend Server in SRU
79 mode. Authentication using HTTP Basic is supported, as is the use
80 of 'x-username' and 'x-password' parameters in the request itself.
82 Added support for a new character set MARC8s identical to MARC8 except
83 that it converts combined characters to single Unicode characters in the
84 Latin-1 range (when possible).
88 ASN.1 compiler 0.4: generates brief Doxygen file header for
89 generated .h/.c files.
91 Utility yaz_iconv now supports conversion to MARC-8.
93 New facilities for the MARC module. The reading - and writing of
94 content are separate methods for the yaz_marc_t handle. The following
95 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
96 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
97 format). Write functions have prefix yaz_marc_write_.. The existing
98 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
99 available. Removed support for OAI-MARC and simplexml (not the
100 simplexml from PHP5).
102 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
103 to be returned for this connection.
105 --- 2.1.16 2006/03/31
107 Allow multiple languages and charsets to be specified with
108 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
109 negcharset iso-8859-1,utf-8
111 Translation of proximity nodes from CQL into PQF now works.
113 Moved to automake 1.8, 1.9.
115 Added function yaz_log_set_handler which allows a log handler to be
116 installed. This handler will be called for all log messages. Output
117 to file is also produced; but that can be disabled by passing NULL
118 fname to yaz_log_init_file.
120 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
122 For SRW (including GFS), accept application/soap+xml as content-type
125 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
126 produces NO stylesheet reference even if a default stylesheet is specified
129 --- 2.1.14 2006/03/14
131 Updated Windows package to include yazd.dll + yazd.lib for the
132 Development component.
134 If the environment variable YAZ_LOG is set, then it is used as a
135 string indicating the default level of logging to use if not
136 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
137 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
138 used as before. So, for example, to omit warnings from YAZ logging,
141 cql_transform() now map structure and other attributes before indexes,
142 so that index-specific structures and other attributes can override
143 defaults. So now a combination of mapping specifications such as:
145 index.dc.date = 1=date-modified 4=5
146 does the right thing.
148 cql_transform() now also respects the "always" mapping specification,
149 which establishes an initial set of attributes to be used for all
150 terms except where overridden by more specific attributes associated
151 with the index, relation or modifier.
153 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
154 which mode to use; one of "post", "get" or "soap" (SRW, default).
156 Fixes for yaz_iconv routines: changed trie-based character set conversions
157 to use only non-negative values for bit fields due to Sun's C compiler not
158 supporting negative values.
160 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
161 sequences where not read correctly. Fix by Rustam Usmanov.
163 Updated win/makefile to use options, settings which makes things
164 compile with VS C 2005.
166 --- 2.1.12 2006/02/01
168 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
170 In ZOOM socket code, use select instead of poll on MacOSX.
172 ZOOM-C now support client-side compilation of CQL into RPN that is
173 sent to the server, enabling CQL to be used against all Z39.50
174 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
175 ZOOM_query object, and submit it using ZOOM_connection_search().
176 The CQL-to-RPN translation uses a configuration file, the name of
177 which must be specified in the Connection's "cqlfile" option.
179 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
180 function, which takes as its start-term parameter a ZOOM_query object
181 (which may have had either CQL or RPN set into it).
184 --- 2.1.10 2005/11/29
186 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
187 GFS to support this as well. Backend handler, bend_srw_update, does the
188 update work. Code contributed by Ko van der Sloot.
190 Allow retrieval of Search Result-1 information in ZOOM by the use of
191 options that are attached to a result set. ZOOM documentation updated
194 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
195 UTF-8 conversion. Patch by Raj Patel.
197 Added option -m to GFS to control formatting of timestamps in log file.
199 Added 'exit' as synonym for 'quit' in yaz-client
201 Added support for specifying SRW resultSetId + resultSetIdleTime in a
202 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
203 for the new members. Patch by Ko van der Sloot.
205 Added support for SRU POST. It is supported for content-type
206 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
208 Do not build the separate Multi-threaded (MT) library libyazthread.la.
209 Instead make the library libyaz.la multi-threaded. Threading as a whole
210 can still be disabled by configure option --disable-threads. Previosly,
211 with older GLIBCs there were problems with MT libs under Apache. This
212 has now been fixed a long time ago.
214 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
217 CQL module modified to be case insensitive for relations/indexes/operations.
219 Fixed bug in CQL transform code: incorrect value relationModifieder
222 Added 'show all' command for yaz-client which retrieves all results
225 Added new yaz-client, xmles, which takes a (private) OID and
226 a document to be sent as an extended service request.
228 Describe new yaz-client commands wait_response and set_auto_wait.
230 Increase TCP/IP listener backlog from 3 (which I am guessing was
231 copied from the SunOS manual entry way back when) so SOMAXCONN, so
232 that the socket will queue as many incoming connections as it's able
233 to handle ongoing connections. In other words, it will never now
234 refuse a connection that it would be able to handle merely because
235 it's not got around to accepting() enough of the pending connections
236 yet. This is the behaviour anyway under Linux, where the listen()
237 argument is ignored; but not under BSD and on systems such as
238 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
239 YAZ-based servers should now be uniform across operating systems in
242 yaz-marcdump uses 64-bit file access on some systems. This is enabled
243 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
244 This allows yaz-marcdump to read large MARC batches (>2 GB).
246 Modified all YAZ source files - except the source which is auto-generated
247 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
250 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
251 corresponding to the existing *_setl() function. These allow option
252 values containing arbitrary valuues.
254 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
255 ZOOM_resultset_sort() in new applications. Its behaviour is identical
256 except that it returns an indicator of whether or not the sort
257 criterion was accepted (0 for OK, -1 for invalid).
261 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
262 MARC output rather than returning "new" buffer.
264 yaz-client warns about unknown init options.
266 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
270 Added support for SRW sort in Generic Frontend Server. Patch
271 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
272 sortKeys - or NULL if none is provided.
274 Fixed bug #307: It was impossible to specify indefinite/no timeout
275 for ZOOM_event. Special timeout value -1 now means indefinite timeout
278 Added support for multiple languages and charsets to be specified in
279 ZOOM. Each charset/language is separated by a blank. If negotiation is
280 in effect in init-response, Option
281 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
282 Code based on patch by Vasiliy Osadchuk.
284 Fixed bug #306: infinite recursion that occurred when calling
285 yaz_log_level_init as the first call (before other log level or
288 Fixed bug in scan handling in front end server: if preferred-Position-In-
289 Response was non-present, a NULL pointer referece was performed.
293 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
294 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
295 now defined for all those error codes. So instead of putting 109 in
296 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
297 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
299 Modified the yaz-marcdump utility to skip garbage bytes between MARC
302 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
304 Program yaz-client now exits and produces an error message if multiple
305 Z39.50 servers are specified on the command line (none or one allowed
308 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
313 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
315 Fixed bug #272: Preserve spacing for CCL terms.
319 Added support for virtual hosts and multiple backend servers for
320 the YAZ frontend server. The configution is XML based and
321 support specificition of CQL to RPN mappings and explain information.
322 See section "Virtual Hosts" in the YAZ manual.
324 Extended OPAC display utility. OPAC display utility renders
325 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
326 to supplement yaz_marc_decode_wrbuf.
328 Fixed a bug in MARC decoder that could caused it to crash for some
329 invalid MARC records. More diagnostics and warnings where added in
330 XML output (warnings, etc are stored in comments).
332 --- 2.0.34 2005/02/08
334 Fixes for UNIX domain sockets. Bug #261.
336 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
338 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
339 Added yaz_marc_subfield_str which defines subfield lead string which is
340 used in YAZ_MARC_LINE format. Default string is blank+$. Added
341 yaz_marc_endline_str which defines end of fields string used in
342 YAZ_MARC_LINE format. Default string is newline.
344 Experimental support for MarcXChange. This format can be produced
345 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
346 http://www.bs.dk/standards/MarcXchange.xsd
348 Added yaz-client commands scansize that sets maximum number of
349 entries to be returned by scan.
351 --- 2.0.32 2005/01/11
353 Added support for SRW scan in yaz-client and Generic Frontend Server.
355 * Added whereInList member to SRW Scan Term.
357 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
359 Fixed NMEM system to return aligned blocks on the smallest boundaries
360 that are suitably aligned for all possible types on the particular
361 architecture YAZ is being built for.
363 --- 2.0.30 2005/01/04
365 Fixed numerious warnings that was issued with newer versions of GCC.
367 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
368 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
371 Make YAZ Generic Frontend Server slightly faster.
373 Enhance (and reduce) logging for Generic Frontend Server.
375 Revert YAZ log system so that it flushes every write operation
376 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
378 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
379 instead of LOG_, due to name clash with syslog(3). LOG_ are still
380 present. New applications should define YAZ_USE_NEW_LOG=1 - this
381 will effectively disable old definitions.
383 --- 2.0.28 2004/11/09
385 Added yaz_log_time_format which specifies log format using
388 Added yaz_log_module_level which returns mask for a module. Value
389 is non-zero mask a if module is enabled; zero if disabled.
391 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
392 in include/yaz/cql.h.
394 Fixed bug #176: Dont throw diagnostics on empty SRU args.
396 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
398 Fixed bug #172: RPM builds does not enable SSL.
400 Doxyfile.in part of dist. Doxyfile generated by configure.
402 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
403 are given and the corresponding component does not exist.
405 Extend CCL documentation in YAZ reference. Describe r=r.
407 --- 2.0.26 2004/10/01
409 Fixed MARC->MARCXML conversion to properly deal with
410 fields, subfields, indicators having non-ASCII characters.
412 Fixed MARC->MARCXML conversion so that ASCII control characters
413 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
416 Added YAZ GFS support for conversion from Z39.50 surrogate
417 diagnostics to SRW surrogate diagnostics.
419 Bug fix: YAZ GFS did not return schema in explainResponse.
421 --- 2.0.25 2004/09/30
423 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
424 now converts recordSchema to elementSetName as well as schema URI.
426 Fixed bug in COMSTACK that prevented HTTP request packages from being
429 --- 2.0.24 2004/09/29
431 Added CCL facility r=r "range" which is similar to r=o "ordered" but
432 does not require white-space before and after the dash in a range, e.g.
433 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
436 Fixed a few AC_TRY_LINK configure tests that did not operate properly
437 due to new GCC removing "redundant" code.
439 Added yaz-client commands scanpos and scanstep that sets preferred
440 position and step-size for scan.
442 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
444 Added CCL utility ccl_qual_buf which parses one or more CCL
445 spec lines in a buffer.
447 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
448 of name and value - ignoring empty lines and comments.
450 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
452 Added odr_get_element_path which returns current element path for an
453 ODR handle. This utility is useful in error handling or user-defined
456 Added ODR_PRINT utility odr_set_stream which is is a more generic
457 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
458 to a write function and pointer to close function. The close function - if
459 non-NULL - will be called during odr_destroy.
461 Fixed bug in CCL parser where truncation char was not removed from
462 right side when truncation=both was in effect.
464 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
467 --- 2.0.23 2004/08/11
469 Fix buffer overrun in CQL parser when dealing with proximity (%).
471 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
472 to UTF-8/UCS conversion is now only based on codetables.xml.
474 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
476 --- 2.0.22 2004/08/06
478 Add support for more "commit changes" in ZOOM (uses Extended Services).
480 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
483 Yet another small fix for configure of SSL.
485 --- 2.0.21 2004/05/14
487 Fix SSL libs for configure when --with-openssl=DIR is given.
489 --- 2.0.20 2004/05/10
491 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
493 SSL comstack now uses yaz.pem certificate file on server side
494 by default. Certificate filename can be configured by calling
495 comstack function cs_set_ssl_certificate_file before cs_bind is used.
497 Fix bug regarding multiple calls to ZOOM_connection_connect.
499 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
501 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
502 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
504 ZOOM now allows inspection of X509 peer certificate for verification.
505 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
507 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
508 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
509 as "modular" but it simplifies things.
511 Added cs_get_peer_certificate to that returns peer X509 PEM.
513 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
514 NULL if SSL is unavailable.
516 Documentation about MARC decoding tools.
518 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
520 --- 2.0.19 2004/03/30
522 Rename CHANGELOG to NEWS to follow GNU style packing.
524 Fix bug with missing initialization of member in init_diagnostics.
525 This bug affects threaded version of GFS server.
527 --- 2.0.18 2004/03/20
529 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
532 Ensure zlib.dll is packed with Windows install.
534 --- 2.0.17 2004/03/17
536 Fix encoding of xsd:string to use text instead of CDATA.
538 Fix endless loop in CQL parser with unbalanced ".
540 Use a more compact way to store MARC-8 conversion tables.
542 --- 2.0.16 2004/03/16 Debian only
544 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
547 Update CQL parser to use new CQL 1.1 modifiers for booleans and
552 --- 2.0.15 2004/03/01
554 Another fix for decoding of XML packed records.
556 --- 2.0.14 2004/02/25
558 Fixes for Chunked encoding. White space not ignored after length spec.
560 Update NS and use default NS for SRW diagnostic elements.
562 --- 2.0.13 2004/02/23
564 Implement ZOOM_resultset_cache_reset which resets record cache.
566 Implement ZOOM_resultset_sort which sorts a result set.
568 Implement chunked HTTP transfer.
570 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
572 --- 2.0.12 2004/02/16
574 Added member 'schema' to bend_explain_rr structure so that backend
575 can specify explain record identifier. Defaults to Zeerex 2.0.
577 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
579 --- 2.0.11 2004/02/16
581 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
584 Added init command for yaz-client which sends "extra" init request.
586 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
587 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
589 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
591 Make ZOOM error code for "invalid query".
593 Fixed compilation for SSL which wasn't properly enabled for all platforms.
595 --- 2.0.10 2004/02/05
597 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
600 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
602 Added option -p <file> to make Generic Frontend Server to write PID file.
604 Added option -D to put Generic Frontend Server in background on its own.
606 Make ZOOM C recognize option "password". If unset, "pass" is used
607 (for backwards compatibility).
609 Fixed a bug in Generic Frontend Server that could make it crash if a
610 client sets characterSetNegotation bit, but didn't pass negotiation stuff
613 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
614 Must be issued before open, in order to be in effect.
616 --- 2.0.9-6 2004/01/12 Debian/Windows
618 Make the SRU server more picky WRT unknown params, etc.
620 Bug fix: ZOOM scan response didn't return displayTerm - when present.
622 New YAZ client command, options, that sets Z39.50 options.
624 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
625 options from a string of tokens (one token for each option bit).
627 Update SRW diagnostic code messages.
629 --- 2.0.9-5 2004/01/07 Debian/Windows
631 Handle user defined stylesheet for SRW/SRU.
633 --- 2.0.9-4 2004/01/06 Debian/Windows
635 Fix bug in decoding of Content-Length.
637 --- 2.0.9-3 2004/01/06 Debian/Windows
639 Fix a bug with decoding of XML packed records.
641 --- 2.0.9-2 2004/01/05 Debian only
643 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
645 Fix bug in SRW/SRU diagnostics decoding.
649 Fixed bug in Generic Frontend Server which could drop records exceeding
650 preferred message size. Reported and fixed by Irina Dijour.
652 Fixed calculation of package size for structured records in Generic
653 Frontend Server. Reported and fixed by Irina Dijour.
655 Fixed namespace for SRW/SRU diagnostics.
657 Fixed SEGV in yaz-client that occured for HTTP connection errors.
661 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
662 this version is incompatible with version 1.0 and older YAZ SRW/SRU
665 CQL changes to reflect recent changes to the specification:
666 * Documentation talks about context sets instead of index sets.
667 * Documentation talks about indexes instead of qualifiers.
668 * The CQL-to-PQF transformer's configuration file now uses
669 "index.set.name = <attributes>" instead of the old form
670 "qualifier.set.name = <attributes>". (Both forms are still
671 understood but the latter is deprecated.)
672 * CQL terms with no explicit index specified are now interpreted as
673 cql.serverChoice instead of srw.serverChoice (which of course
674 behaves exactly the same.)
678 MARC conversion can now generate ISO2709 output in another
679 character set. yaz-marcdump uses this facility if you invoke it
682 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
683 functions from there can be used from C++.
687 Frontend server now transfers memory from decoded packages to stream
690 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
691 references to show up.
693 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
694 the ZOOM Abstract API. The older names for the same options are still
695 also supported for the benefit of old applications.
697 ZOOM-C supports "implementationId" and "implementationVersion" options
698 to go along with "implementationName". These allow the user code to
699 specify identification strings to be sent to servers.
700 Add OID for the new ExtLite attribute set.
702 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
703 as requested/supplid by Ere Maijala <ere@atp.fi>
705 For generic frontend server, reverse the order of
706 "toolkit-supplied / application-supplied" strings sent as implementationId,
707 Name and Version. Also, remove the spaces around the slash. This brings
708 the GFS in line with the behaviour of ZOOM-C on the client side.
710 Add function ZOOM_scanset_display_term.
712 yaz-client shows scan displayTerm if present.
714 Utility yaz-iconv is now installed by default along with the man page
717 Extend configure check for OpenSSL to use pkg-config where available (such
720 Incorporate patch by Morten Bogeskov which allows a Unix file socket
721 server to specify uid/gid/mask for socket using the format
722 unix:[user=uid,][group=gid,][umask=mask,]file=path
723 If file= is omitted the existing format is assumed, e.g.
725 in which case the mask is 0666 (rw for everybody).
727 Major restructure of YAZ source. All source in libyaz is in src directory.
728 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
729 util (utility programs such as ASN.1 compiler, yaz-marcdump).
731 Added man page for utility yaz-marcdump (used to be called marcdump).
732 yaz-marcdump is installed by 'make install'.
734 Fixed a memory leak in Generic Frontend Server that occurred when decoding
735 of incoming package failed.
737 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
739 Change prototype of odr_perror: add const to message string.
741 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
743 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
744 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
745 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
746 DNS lookup. There should not be any compatibility problems with this
747 assuming that blocking=1 or 0 is used.
749 Fix bad reference in UNIX comstack in function cs_addrstr.
751 Fix for compilation on AIX.
753 The generic front-end server (server/seshigh.c) now supports returning
754 Init diagnostics to the client in User-information-field, in
755 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
760 Allow any CQL relation (not just all,any,exact,scr).
762 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
763 that features the same UI.
765 Implemented command update0 in YAZ client which is equivalent to
766 update but uses old of Ext Update ASN.1.
768 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
769 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
770 Previously no OID was used for this info.
772 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
773 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
774 returns 'malformed search term' otherwise.
776 SortResponse member resultCount now set to NULL in sort handler of
779 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
782 Add three new utility functions for translating OIDs between various
783 formats -- symbolic name such as "Usmarc", minus-1-terminated int
784 arrays and dotted strings such as "1.2.840.10003.9.5.1":
785 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
786 char *oid_to_dotstring(const int *oid, char *oidbuf);
787 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
789 Reverted modifications for ES Update definition for z_IU0Update
790 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
791 is back to YAZ 2.0.2.
793 String value attributes for CCL parser.
795 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
796 which their FirstSearch server returns in Init responses, sometimes
797 carrying useful diagnostic information when Init fails. This has the
798 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
799 "z39.50/oclcui.asn", where its definition is somewhat different from
800 what OCLC document on their web-site, as required to interoperate with
803 Support for anonymous authentication in yaz-client. Use the command
806 * Fix the OID of the Index Data-local "admin" Extended Service from
807 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
808 the 1000, which indicates a locally-defined OID, was a mistake.
812 Fix CCL directive @case handling so that it affects string match for
813 both CCL keywords and qualifiers.
815 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
816 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
817 Decoder has been updated with ASN.1 changes as listed in
818 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
819 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
820 z_IUUpdate, remains unchanged.
822 ZOOM_record_get may now return a record in a specific character set.
823 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
824 "from" is the character set of record as returned by target. "to" is
825 the character set to be returned. If omitted, "to" is UTF-8.
827 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
829 New ODR utility, odr_getelement, which returns name of element for
830 which encoding/decoding failed.
832 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
833 in cases where a required element was omitted.
835 Bug fix: some MARC8 sequences were not converted.
837 New ZOOM option "step" which specifies number of records to be
838 retrieved in one chunk. Used in conjunction with "start" and "count".
840 SRW support for yaz-client. Use scheme http: to use it, e.g.
843 yaz-client no longer does (un)intelligent character set conversions
844 by default. Can be enabled with charset and marc_charset commands.
846 xmalloc trace fix for 64-bit systems such as DEC alpha.
848 Solaris 2.6 compile fix.
850 New function, cql_strerror() translates SRW error codes, as returned
851 by cql_transform_error(), into human-readable English strings. Used
852 in yaz-client diagnostics when appropriate.
854 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
855 converts it into a type-1 query which is sent to the server. This
856 makes CQL available for use with all Z-servers, as opposed to the tiny
857 minority that can handle CQL queries themselves.
861 New Debian package layout similar to the Redhat Package layout.
863 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
864 and search result respectively.
868 Redhat package is now several packages: libyaz (runtime libraries),
869 libyaz-devel (development and documentation, and yaz (utility programs).
870 Package spec file by Morten Bøgeskov.
872 New member 'schema' in struct bend_fetch_rr which the name of requested
873 schema (SRW/SRU) for record (or NULL if none was given). The fetch
874 handler MAY set this to reflect the schema of the returned record.
876 New member 'display_term' in struct scan_entry. GFS now sets member entries
877 and allocates scan entries to be filled by user scan handler. In previous
878 version, entries member was allocated by the scan handler. That still works,
879 but the GFS will ignore member display_term - assuming it was NOT set by
880 the handler. The fact that the GFS now allocates the entries both allows
881 for new members and makes a scan handler easier to write.
883 Fix CQL lex buffer overflow.
885 SRW/SRU recordPacking. For SRW default recordPacking is string. For
886 SRU default recordPacking is string.
888 SRU protocol support for frontend server.
890 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
892 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
894 Added scan for the ZOOM shell (zoomsh).
898 * String Identifers for Schemas (Amendment 5).
899 http://lcweb.loc.gov/z3950/agency/amend/am5.html
900 Old definition for schema
901 Odr_oid *schema; /* OPT */
906 Z_InternationalString *uri;
907 #define Z_Schema_oid 1
908 #define Z_Schema_uri 2
911 * resultCount parameter to Sort Response (Amendment 1).
912 http://lcweb.loc.gov/z3950/agency/amend/am1.html
914 Support for SRW 1.0 over HTTP. This is an optional feature and
915 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
918 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
919 on the same port. SRW SearchRetrieveRequests are mapped
920 to bend_init,bend_search,bend_fetch,bend_close.
922 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
924 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
925 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
927 ZOOM connections are SRW based if schem http is used for hostname
928 in connect, e.g. z = ZOOM_connection_new("http://myserver");
929 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
931 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
932 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
933 distance=n, order=true/false, relation=le, prox unit=word. If
934 n is omitted, distance 1 is used.
936 Fixed problem with C compiler include path in wrong order.
938 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
939 on Solaris. Patch from Ko van der Sloot.
941 New MARC decode API. All new functions operate on a yaz_marc_t
942 handle. The most important new functions are: yaz_marc_create,
943 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
944 decode and destroy respectively. Decoder can produce formats
945 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
946 include/yaz/marcdisp.h.
948 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
949 to UTF-8, UCS-32, wchar_t or Latin-1.
951 * Prototypes for yaz_iconv_-functions moved to separate header
952 include/yaz/yaz-iconv.h.
954 Make a few private functions 'static' in unix.c. This prevents
955 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
957 For ZOOM connection, the options targetImplementation{Id,Name,Version}
958 are set when Init Response is received.
960 New function ZOOM_connection_error_x similar to ZOOM_connection_error
961 but returns diagnostic set as well.
963 New function yaz_strerror which is a portable wrapper for
964 strerror/strerror_r/GetLastMessage.
966 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
967 is returned for MARC. If type is "oai", then OAI MARC is returned.
969 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
974 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
976 Fix bad race conditions on SIGTERM and terminate gracefully in
979 Move retrieval (data1) module to Zebra since nobody seems to be
982 Add GRS-1 render for ZOOM using same format as yaz-client.
986 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
988 Fix broken ESpec handling in data1 module.
990 SGML reader parses comments and makes them part of the data1 tree.
992 Added several type casts so that YAZ compiles as C++ code.
994 ZOOM didn't handle PDU encoding failures properly.
996 Added more Bib-1 diagnostics (approved extensions).
998 GNU configure: better check for iconv.
1000 More portable use of accept, getpeername. Check for socklen_t. Use
1001 int/size_t if socklen_t is not defined.
1005 PQF parser rejects bad queries - including those with extra
1006 characters in them. PQF parser used to silently ignore that.
1007 Cleaner API for PQF added, which allows you to get detailed
1008 error information for bad queries (see yaz/pquery.h).
1010 Fixed bug in ZOOM_record_get for type "database".
1012 Implemented mini iconv library supporting conversions between
1013 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1015 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1017 --- 1.8.9 2002/08/20
1019 Fixed ZOOM C record cache so that preferredRecordSyntax and
1020 elementSetName is used to check for already fetched records.
1022 --- 1.8.8 2002/08/02
1024 Added three members in bend_initrequest structure to facilitate
1025 character set negotiation.
1027 Fixed a bug in frontend server that could cause indefinite
1028 loops under rare conditions.
1030 Revised character set utilities (charneg.h) so that encoding
1031 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1033 For PQF, directive @term <type> sets term type for Scan/Search.
1034 Here <type> is general, string, numeric, null. The term type
1035 is inherited - just like @attr.
1037 New call odr_set_charset that sets character set conversion for
1038 international-strings on a ODR stream. Prototype is:
1039 int odr_set_charset(ODR o, const char *to, const char *from);
1040 The InternationalString is still represented as C string in YAZ
1041 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1042 won't). On the protocol level, you can use any encoding.
1044 Support for UNIX sockets in ZOOM.
1046 Solaris recv sometimes returns errno == ENOENT. It is treated as
1047 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1049 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1050 both client and server. Code by Morten Bøgeskov.
1052 --- 1.8.7 2002/05/22
1054 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1055 that they can be used directly from Visual Basic. You must recompile
1056 your windows APP if you're using ZOOM.
1058 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1059 Commands "lang" and "charset" sets language and character set respectively.
1060 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1061 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1063 Attributes from multiple CCL fields may be OR'ed rather than merged
1064 using directive "@field or". Fields are still merged by default -
1065 equivalent to "@field merge".
1067 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1070 Fixed bug in zget for parameter ExtendedServicesResponse.
1074 --- 1.8.6 2002/03/25
1076 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1078 Client displays USR.1:SearchResult-1 (hits per term).
1080 Additional Search Info for search in Generic Frontend Server.
1082 Fixed CCL parsing of "field=s".
1084 WIN32 installer - using the excellent NSIS software from nullsoft.
1086 Fixed CCL parsing of "field = - <number>".
1088 Added function yaz_marc_decode that decodes MARC for line mode
1089 display or XML (similar to that used by JZKit).
1091 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1092 Z39.50. But ISO/ILL was, however.
1094 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1095 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1097 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1098 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1100 --- 1.8.5 2002/02/03
1102 New YAZ client features: Command completion and new commands:
1103 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1104 Code provided by Jacob Poulsen.
1106 New call oid_trav, that visits all registered OIDs via callback.
1108 Function ZOOM_record_get now returns const char pointer rather than
1109 void pointer. It saves a lot of type casts.
1111 For YAZ client, command "auth" now allows you to set authentication
1112 in IdPass style. It is enabled when three tokens are given - order
1113 is user, group and password.
1115 Fix memory leaks in MARC record handling for ZOOM.
1117 New option for YAZ client, -k <kilobytes> that sets
1118 maximum record size. Similar to -k option for generic frontend
1119 server and yaz-ztest.
1121 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1123 Prefix query parser reports "fail" when bad attribute set is given.
1125 Fix in MARC decoder. Proximity logging. Fix for attribute set
1126 in scan handler for server. Patches by Shigeru Ishida.
1128 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1131 Configure option --with-openssl=<dir> now works when a directory is
1132 specified. Patch provided by Morten Bøgeskov.
1134 New option for YAZ client, -u <auth>, that sets authentication.
1136 ZOOM fix: error information was sometimes "missing", since error
1137 was cleared/reset too when it shouldn't.
1139 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1141 --- 1.8.4 2002/01/04
1143 Scan for ZOOM API. New object ZOOM_scanset. New functions
1144 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1145 ZOOM_scanset_destroy.
1147 New ZOOM function, ZOOM_connection_last_event, that returns type
1148 of last event (such as "receive data", "send data", "apdu received",
1151 New ZOOM option, schema, that specifies schema for retrieval.
1153 New CCL feature. Qualifiers can be aliases for one or more
1154 other qualifiers (if more than one is given, OR is used).
1156 ZOOM uses named result sets if target supports it.
1158 Two new YAZ client commands: . (dot, which sources a script of YAZ
1159 client commands), and ! (to execute shell command.). Implemented
1162 Working on Debian packages.
1164 --- 1.8.3 2001/11/19
1166 YAZ client enables named result sets only if target supports it.
1168 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1170 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1171 with key="host" to get same result.
1173 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1174 Function Z3950_resultset_record(s) returns references to records
1175 "owned" by resultset. To become owner use Z3950_record_clone.
1177 Function z_ext_record handles Extended Services. Thanks to
1180 --- 1.8.2 2001/11/12
1182 CCL Parser fix: ignore token comma when dealing with and-lists.
1184 Documentation updates for COMSTACK.
1186 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1187 Changed prototype Z3950_records. For some functions, int parameters
1188 were changed to size_t.
1190 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1193 New MARC decode/display function, marc_display_exl, which properly rejects
1194 non-ISO2709 records. YAZ client uses it.
1196 --- 1.8.1 2001/10/29
1198 Fix bug: local attribute set wasn't set correctly in PQF strings.
1202 * Old Z39.50 codecs no longer supported.
1204 Added ZOOM C binding. See http://zoom.z3950.org/
1206 Renamed states for COMSTACKs to avoid confusion with events.
1208 Implemented cs_look and proper cs_rcvconnect.
1210 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1212 Configure detects POSIX threads on OpenBSD.
1214 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1215 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1217 When error is returned from present handler, non-surrogate diagnostic
1218 is returned in present response (and fetch handler is no longer called).
1220 * Minor adjustments to pquery parser (PQF). Token characters may be
1221 escaped by using backslash (C-style).
1223 PQF parser allows string attribute values to be specified. For @attr,
1224 non-numeric characters after the equal-sign are treated as strings
1225 (e.g. @attr 9=title).
1227 CCL trunction character may be defined (@truncation in file)
1229 * function zget_ExtendedServicesRequest sets waitAction to
1230 waitIfPossible (was wait).
1232 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1235 CCL operator names may be set in field definition files (CCL_bibset).
1236 See ccl/bib1 for an example.
1238 Fixes in ASN.1 compiler for C++ compatibility.
1240 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1241 and "op_or" to avoid conflict with C++.
1243 Fixed problem with GNU readline detection on Redhat 7.0.
1245 Added step-size for Scan backend handler.
1247 Fixed bug that made the frontend server crash when no attribute
1248 set was specified for scan.
1250 Front-end server automatically switches to original working directory
1251 when installed as an NT service. Previously -w had to be specified to
1254 Added extended attributes for retrieval module (data1), so that data1
1255 records carry d1_readXML/SGML attributes. d1_read also supports
1256 null-data rules ( <tag/>)
1258 On UNIX when POSIX threads are available, a separate library libyazthread
1259 is created. Programmers should link with that library and the yaz library
1260 when using threads. The reason for the split was that some applications
1261 on Linux, such as Apache, doesn't work well when using shared objects that
1264 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1265 (or any frontend server) in SSL mode by specifying ssl: followed by
1266 address. Only tested on UNIX.
1268 Added feature for CCL module. Virtual structure s=al or s=ol generates
1269 and-list and or-list respectively instead of phrase search.
1273 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1274 log_mask_str. This was done to avoid name conflicts with other libraries
1275 (such as other PHP extensions).
1277 Added raw OID member for preferred record syntax (request_format_raw)
1278 and returned record syntax (output_format_raw) for backend fetch method.
1280 Config file yaz-config now accepts options so that it returns specific
1281 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1283 Shared library support for UNIX using GNU libtool.
1285 * Modified backend interface. Request/Response struct's replaced by
1286 one read/write C struct. For example bend_fetchrequest and
1287 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1288 Every handler - even search has to be registered in bend_init
1289 handler. This means that the YAZ library no longer refers to
1290 external functions and it makes it possible to make the whole
1291 thing a single DLL/SO.
1293 Added Segment handler for backend server.
1295 Added Zmbol/Zebra administrative functions to YAZ client.
1297 Threaded frontend server on UNIX (when POSIX Threads are available).
1298 Starting the server with option -T enables multi-threading.
1302 Added configure option --enable-comp/disable-comp to control use
1303 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1304 located in sub directory asn.
1306 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1307 in ${exec_prefix}/bin along with the other programs yaz-client and
1310 GNU automake used to maintain makefiles.
1312 Added several OID's.
1314 Changed retrieval module so that we can load records with no abstract
1315 syntax defined. Tagpaths in these records are fully composed of string
1318 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1322 On UNIX, the generated makefile now supports a proper 'make install'.
1323 The prefix can be set via GNU configure to set the install location
1324 (default is /usr/local).
1326 * YAZ programs client and ztest were renamed to yaz-client and
1327 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1328 locations, such as /usr/bin,/usr/local/bin,etc.
1330 * YAZ Header files were moved from include to include/yaz. YAZ Header
1331 files are referred to as include <yaz/log.h> rather than <log.h>.
1332 The YAZ include path (-I ..) is therefore the same as before. Programmers
1333 should update their #include statements or use -Ipath/include/yaz
1334 instead. The main motivation for doing this change is that YAZ header files
1335 can be installed in "standard" locations /usr/include,/usr/local/include
1336 without introducing conflicts, since ALL YAZ header files are stored
1337 in subdirectory yaz (under /usr/include for example).
1339 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1340 rather than project/workspace files. We switched because project files
1341 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1344 Changed name of logging function, logf, to yaz_log, to prevent name
1345 clash with some math-log functions. The YAZ header log.h defines logf
1346 to yaz_log (#define) so there should be no incompatibilities by this
1349 Added bend_start/bend_stop handlers for server. These handler are
1350 called on start/stop of server. For windows they are called whenever
1351 a service is started/stopped.
1353 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1354 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1355 in util/yc.tcl. The auto-generated C code structures are, in a few
1356 cases, incompatible with the old decoders. There are differences in the
1357 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1358 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1359 The preprocessor variable ASN_COMPILED is defined when the compiled
1360 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1361 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1362 wish to use the old encoders/decoders you can specify --disable-yc
1365 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1366 version so that it supports both new - and old version of DB Update
1368 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1369 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1370 change. The name parameter can be set to 0 in which no name is specified
1371 for the construction. The macros odr_implicit and odr_explicit sets name
1372 parameter to zero for the construction involved. New macros
1373 odr_implicit_tag and odr_explicit_tag are similar to the others,
1374 except that a name parameter is added. For programmers' that don't use
1375 ODR they probably only need to change the call to z_APDU and z_External.
1377 Added access control facility by interfacing the TCP wrapper library.
1378 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1379 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1380 name of the daemon and enables the access control as specified in
1381 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1383 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1384 den Dool <H.M.vdnDool@kub.nl>.
1386 Added reference ID parameter to most functions in server API - refer
1387 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1389 Changed name of ccl library to libccl.a (was ccl.a).
1391 Fixed bug in decoder for Explain (Category TargetInfo).
1393 Added support for GNU readline in client. Thanks to Jacob Poulsen
1394 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1396 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1397 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1398 IMPLEMENTATION! This change was made to the development version before
1399 the ZIG decided to retract the amendment. If any users MUST be
1400 compatible with the original Update definition, PLEASE CONTACT US, and
1401 we will include a separate definition corresponding to the old Update
1402 ES. Note that because of the change to the ASN.1 of the
1403 TaskPackageRecordStructure we cannot define a single structure that
1404 will support both versions.
1406 * Added const modifier to buffer parameter for some ODR/BER encoding
1407 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1408 completeWAIS, odr_dumpBER.
1410 Fixed bug in client.c which caused a crash when a scanResponse didn't
1411 contain positionOfTerm.
1413 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1414 * will cause an error in a client if a non-YAZ target sends both a
1415 * list of Scan entries and non-surrogate diagnostics.
1417 Retrieval module enhancements. Tag sets may be typed in the reference
1418 to it. From the .abs-file the "tagset" directive takes a third optional
1419 integer type for the tag set referenced. From a .tag-file the "include"
1420 directive takes a third optional type as well. The old "type" directive
1421 in the tag set itself is still recognized but acts as the default type
1424 Backend interface change. Individual Scan terms returned from bend_scan
1425 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1426 in include/backend.h.
1428 Retrieval module enhancements. Multiple tag sets and attribute sets may
1429 be specified in abstract syntax specs. Revised the error/warning for
1430 logging messages reported by the retrieval module when reading the
1433 Object Identifier system (oid_..) changed. The API is backwards
1434 compatible but the oid-routines now allocates new OID's when needed.
1435 Raw OID's may be specified in oid_getvalbyname.
1437 YAZ now uses GNU configure to generate Makefile(s).
1439 * Minor changes in some of the member names of DeleteResultSetRequest and
1440 DeleteResultSetResponse. See include/proto.h.
1442 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1443 and added member 'languages' in TargetInfo (which was missing).
1445 Changed the way attribute sets are handled in the retrieval
1446 module. These are now cached, just like the abstract syntaxes
1449 Changed YAZ so that it links with compiled ASN.1.
1451 Added Explain-schema definitions and mapping routines. The following
1452 Explain categories have been implemented: AttributeDetails,
1453 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1455 Fixed minor bug in Windows version of Server Library.
1457 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1459 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1461 Added EXTERNAL: UNIverse Resource Report (non-standard).
1463 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1464 ENUMERATED and SET OF.
1466 * Added 'const' to some of the char pointer arguments for the
1467 functions, data1_read_node, data1_getelementbytagname,
1468 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1471 Fixed bug in data1_insert_taggeddata - the last_child member of
1472 parent wasn't initialised.
1474 * Changed data1_read_record and data1_read_node so that the supplied
1475 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1476 doesn't refer to any parts of the "SGML"-buffer.
1478 Fixed bug in server library (Windows version of statserv_remove).
1480 * Changed code so that it compiles as C++. The type definition
1481 of Odr_fun which is a member of Odr_arm was changed. The result is,
1482 that an explicit typecast is needed for the fun pointer when
1483 using Odr_arm - as in:
1484 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1486 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1488 Implemented the new structured date and time definition as approved
1489 by the ZIG. Added schemaId element to the specificTag in Espec-1
1490 (also approved at the last ZIG). Thanks to RVDM.
1492 Added some Object identifiers (RVDM).
1494 Changed the Update Extended Service (RVDM).
1496 Added command "refid" to client which specifies referenceId for
1497 the following requests.
1499 Implemented extended service handling for server. See ztest.c
1500 for an example as well as backend.h. New handlers are registerd
1501 in the Init handler.
1503 * Changed interface for sort in server.
1505 Added new members to statserv_options_block. It allows a server
1506 to read options from another source than just the command line. Thanks
1507 to Charles Woodfield.
1509 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1510 renamed to zboolean. Some C++ compilers complained about the name.
1512 Minor changes to gils.abs. Added index 's' (sort) on title
1513 and date/time-last-modified.
1515 --- 1.4pl2 1998/1/30
1517 Fixed bug in server library regarding inetd mode (-i). This bug
1518 was introduced by release 1.4.
1520 --- 1.4pl1 1998/1/29
1522 Added sort facility in client and backend server interface.
1524 Fixed problem with dependencies in Makefile(s).
1526 Fixed bugs for encoders/decoders of extended services and
1529 Implemented sub-tree feature for schemas. Sub-trees are
1530 referenced in *.abs-files. See explain.abs for an example
1531 of the use of this feature.
1533 Modified bib1.att; local attributes for ANY didn't include
1534 ANY itself (only affects use of the retrieval module).
1536 Fixed bug in plain SGML reader in function data1_read_node:
1537 tags with prefix "var" was incorrectly interpreted as variants.
1539 Added feature "sub-schemas" to enable references to - and definitions
1540 of - group of elements.
1542 * Removed member parent from type data1_element (in data1.h).
1544 Implemented function odr_nullval() that returns the value of
1547 * Removed member num_children from data1_node (in data1.h).
1549 Made NT service interface part of the server library. The
1550 function statserv_main uses the NT service when required and
1551 calls the statserv_start / statserv_close routines.
1553 Routine zget_SearchRequest and zget_PresentRequest fills
1554 resultSetName/Id member with "default" instead of "Default".
1556 Fixed memory leak in server. Request queue member wasn't freed.
1558 Fixed nmem_exit so that memory is freed.
1562 Revised the CCL parser utility to be thread safe.
1564 Added function, oid_ent_to_oid, to replace the function
1565 oid_getoidbyent, which is not thread safe.
1567 * Added nmem_init and nmem_exit to initialize and release
1568 NMEM resources. Function nmem_init should be called once in the
1569 initial thread before NMEM/ODR is used. statserv.c and client.c
1570 have been changed accordingly. The change was necessary to make
1571 NMEM thread safe. The NMEM memory pool is shared amongst threads
1572 in a process. Unix-based applications will still work fine without
1575 Added NT Services interface for the the Z39.50 (statserv) Server.
1576 Refer to the ztest.c source on the usage.
1578 Windows 95/NT port using MSVC5.0. Project files are included in the
1581 * Defined new 'global' handle for the retrieval (data1) system. The
1582 new handled, data1_handle, describes the state of the data1 system.
1583 This handle is passed as first argument to virtually all
1584 data1 related routines. The functions data1_create and data1_destroy
1585 creates and destroys a data1 handle respectively.
1587 Added ODR encode stream member to all backend request structures
1588 init, search, scan etc. This stream should be used to allocate all
1589 memory used for the response when thread safe operation is needed.
1591 Changed the comstack utility, cs_addstr, to be thread safe. The
1592 returned hostname string returned by the function is now part the
1595 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1596 function. The cs_straddr takes a COMSTACK handle as argument, so this
1597 function must be used after cs_create and before bind/connect.
1598 This function is thread safe.
1600 Moved test server to 'ztest' directory - generic server code still
1601 in 'server' directory.
1603 Made prefix query (pquery.c) utility thread safe.
1605 Added new function modifier YAZ_EXPORT to 'export' public DLL
1606 functions when using windows (see include/yconfig.h).
1608 Added definitions to the OID database (util/oid.c) (RVDM).
1610 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1612 Added call to ccl_rpn_delete in client program.
1614 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1615 release of RPN structure.
1617 Added support for C++, headers uses extern "C" for public definitions.
1618 With input from RVDM.
1620 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1621 Thanks to Ronald van der Meer (RVDM).
1623 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1625 Added support for private extensions to the OID database
1626 (oid_setprivateoids()). Thanks to RVDM.
1628 Added optional, physical ANY (key replication)
1630 Fixed null-reference problem in GRS-1 output filter.
1632 Proximity operator added to Prefix Query Format (PQF).
1634 In test client command "base" accepts multiple databases.
1636 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1640 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1642 Smallish bug-fixes in the new encoders/decoders (explain).
1644 Bug fixed in DeleteRequest.
1646 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1648 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1650 Added SOIF syntax (using private OID for now) to retrieval module and client.
1652 Added Update extended service.
1654 Added SearchResult-1 additional info structure.
1656 Added optional CCL (ISO8777) interpreter as separate module. Available
1659 --- 1.2 1996/6/10 (1st anniversary release)
1661 Added Summary record syntax. Lightly tested.
1663 Added OPAC record syntax. Untested.
1665 Added ResourceReport service encoders/decoders. Untested.
1667 Fixed bug in z_Unit - wrong tagging on unitSystem.
1669 Fixed bug in the DiagRecs decoder.
1671 Added options for max PDU size and session timeout to frontend-server.
1673 Added documentation of query-language parsers and other supporting utilities.
1675 [frontend-server] Added Attribute set to the bend_scanrequest API.
1677 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1678 surrogate diagnostics were generated.
1680 [retrieval] Allow multiple local values for attribute.
1682 [retrieval] Allow multiple attributes per element in .abs files. index type.
1684 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1686 --- 1.1pl2 1996/4/10
1688 Minor changes, mostly specific to Zebra's requirements (retrieval)
1692 Repaired bug in frontend server when running multiple listening
1693 endpoints in dynamic mode.
1695 z_External() now won't break if a known, ASN.1 value comes encapsulated
1696 in an octet-string. The value will pass through unmodified in an Odr_oct.
1698 Added a bit of code to the demo client to decode & display
1699 ASN.1-structured records represented in the octet-aligned branch of
1700 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1702 Added z_ext_getentbyref() to the ASN module. Doc updated.
1704 * Completed the SCAN definition in the ASN module. This may break SCAN
1705 code based on older YAZ-versions at compile-time. The fix is easy -
1708 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1709 under the SCAN definition. Remember to initialize this, server-people.
1711 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1712 that this does not extend to ODR and ASN.
1714 Comstack allows insertion of established socket (primarily for
1715 inetd-operation of servers). Doc updated.
1717 Front-end server can now start from the inetd in TCP mode. Doc
1720 --- 1.0pl4 1996/1/24
1724 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1725 the rank and record number.
1727 Adjustments to the frontend server.
1729 Fixed diagnostic BER dumper. It ignored the file argument.
1733 Various changes to retrieval module.
1735 Changed the union discriminators of the protocol files from enums to
1736 ints paired with #defines.
1738 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1741 *Changed operator in the RPN structure to 'roperator', again to avoid a
1744 Fixed problems in Explain decoders/encoders.
1746 --- 1.0pl2 1995/12/6
1748 Memory bug in log module fixed.
1750 --- 1.0pl1 1995/12/5
1752 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1754 Bug in Explain DatabaseInfo module fixed.
1756 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1760 The shift to v1.0 signals that we now consider the *core* functionality
1761 of YAZ reasonably stable (the core being more or less equivalent to
1762 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1763 tested (Explain not at all - though that will happen soonish).
1765 Minor changes to code to support Windows port.
1767 Various minor changes after we're getting to use GRS-1 & co. more.
1769 Added Espec-1 format.
1771 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1772 of the protocol and it cannot be selected when encoding (maps into 'string'
1773 when decoding). Needed to talk to some servers.
1775 Demo client can request simple element set names.
1777 Added Diagnostic Format encoders/decoders.
1779 Added simple Close handling to frontend server (no hooks for resource
1780 reporting yet), and demonstration client.
1782 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1784 --- 1.0b3 1995/08/24
1786 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1787 handled incorrectly when records were requested in the searchResponse. This
1788 will only affect you if you use the frontend-server.
1790 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1791 Test-client will ask for and print GRS1. Ztest will return dummy records
1794 Added Explain encoders/decoders to the service-level API. Untested.
1796 Added Extended Services: Item Order encoders and decoders to the Service-
1797 level API. Untested. We could use a recent copy of the pertinent bits
1798 of the ILL protocol to add those bits.
1800 Added diagnostic format 1 encoders/decoders to the service-level API.
1803 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1804 odr_cons.c, which causes a more correct output.
1806 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1807 was always set to 0 when no records were requested in the searchRequest.
1809 * Added better external-handling. This shouldn't harm old code that
1810 *encodes* externals. It can break code that looks for a
1811 'single-ASN1-type' representation, since those types that are known
1812 are now decoded immediately. Look at the SUTRS sample code in
1813 seshigh.c and client.c. Documentation updated.
1815 Handling of structured records in bend_fetchresponse. Length -1 marks
1816 structured record, type is deduced from format field.
1818 --- 1.0b2 1995/06/27
1819 Fairly quick maintenance release to add SUTRS support.
1821 Fixed handling of SUTRS records in the demonstration client.
1823 * Added format field to the bend_fetchrequest and bend_fetchresponce
1824 structures of the backend API (frontend server). When the record is
1825 returned, the value of the format field is mapped to an OID. The
1826 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1827 of the record. The special value VAL_NONE in the bend_request means
1828 that no specific format was requested by the client. Documentation
1829 updated accordingly. Test server (ztest) will return a fixed dummy
1830 SUTRS record if your client requests SUTRS.
1832 Documentation updated accordingly.
1834 You can now set external libraries and RANLIB support in the top-level
1838 First public release.
