3 Updates for SRU Update by Ko van der Sloot:
4 1. Changed name from "operation" to "action"
5 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
6 versions in the code, marked as 'backward compatible'.
7 3. Added diagnostics for SRU Update.
9 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
11 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
13 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
15 For GFS, fixed problem with SRU diagnostic 'First record position out of
16 range' being issued for 0 hits.
18 zoomtst10 part of Windows Build.
22 Implemented yaz_filepath_comp which splits a path into file path
23 components (required by Zebra 2.0.3+).
25 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
26 BSD inspired license until now so this should not have any real impact on
27 anybody. See http://www.opensource.org/licenses/bsd-license.php
29 Fixed bug #687: Missing log lines.
31 Fixed bug #678: CQL to PQF translation does not preserve double-quote
34 Fixed bug #689: SRU diagnostics to be added.
36 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
37 whether a connection is idle (no more work do do).
41 Change type of optval from long to int for invocation of setsockopt with
42 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
44 Added support for specifying the max log file size for the Generic
45 Frontend Server. The size is given with option -r.
49 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
53 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
56 Fixed bug in Generic Frontend Server that could cause a server to stop
57 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
59 For the generic frontend server, the maximum record size is used as maximum
60 size of incoming packages (SRU + Z39.50). The value until was previously
61 only used in Z39.50 Init negotiation and, later, in a session controlled
62 sizes of records returned. This is controlled using -k option. It can be
63 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
67 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
70 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
72 New option for yaz-marcdump -lpos=value which allows setting a portion
73 of MARC header to a certain value.
75 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
77 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
78 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
82 Fixed problem with SRU mode type (soap, get, post) for yaz-client
85 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
89 Fixed MARC ISO2709 encoding routines to deal with character set
92 Minor changes to GFS logging. Database included in search request log
95 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
96 cached/multiple records.
98 Shared libraries are built by default on Unix+configure.
100 Changed cql2pqf transformation to use a different evaluation order. The
101 new order is: always, relation, structure, position, truncation, index
102 and relationModifier. Old order was: always, relation, relationModifier,
103 structure, index, position, truncation. Note that the the latter ones
104 override former ones for identical attributes.. The new scheme means that
105 it is possible to override any existing attribute with a relationModifier.
106 And also that it is possible to override everything for the index rule
107 (except the ones listed in relationModifier). No order is perfect but this
108 one, we believe, covers more real cases.. The "always" should have been
109 called "default", since the attributes there can be overridden with all
112 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
113 compilation phase, but also for yaz-config --cflags output. This allows
114 us to have public headers with Libxml2 stuff in them . It should also,
115 eventually, make Libxml2 checks redundant in packages using YAZ, such
118 --- 2.1.22 2006/06/15
120 Changed SRU update structure bend_update_rr so that SRU diagnostics are
121 stored in uri, message and details.. Previously diagnostics were stored
122 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
123 compatibility.. but he's probably the only one affected, so.
125 Added support for CCL, compiled on the client side, in ZOOM-C. This
126 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
127 input; the resulting query objects can be used for for searching with
128 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
130 YAZ' configure searches for OpenSSL by default.
132 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
133 SL_CTX_use_certificate_file. See
134 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
135 for more info. Thanks to Ko van der Sloot.
137 --- 2.1.20 2006/06/02
139 Bug #600: SRU GET, POST support for yaz-client. Introduced
140 command 'sru' which selects method SOAP/GET/POST.
142 Allow missingValueAction to be specified for the sortspec string -
143 function yaz_sort_spec. By default, the missing value action is null.
144 Use ! to specify "abort". Use = followed by stringvalue to specify default
147 Ensured that Present-handler (if defined) is called in GFS before any call to
148 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
149 searchRetrieve requests.
151 Documentation for YAZ is now based on the Docbook XML/XSLT using
152 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
153 is no longer depending on jade/openjade or docbook-to-man scripts.
154 PDF is no longer part of the distribution - but can optionally be
155 made using DSSSL/jadetex or FOP.
157 Added retrieval handling support in Generic Frontend Server to support
158 conversion between MARC/XML as well as XSLTtransforms. See
159 etc/yazgfs.xml for an example.
161 Added Authentication support to Generic Frontend Server in SRU
162 mode. Authentication using HTTP Basic is supported, as is the use
163 of 'x-username' and 'x-password' parameters in the request itself.
165 Added support for a new character set MARC8s identical to MARC8 except
166 that it converts combined characters to single Unicode characters in the
167 Latin-1 range (when possible).
169 --- 2.1.18 2006/04/24
171 ASN.1 compiler 0.4: generates brief Doxygen file header for
172 generated .h/.c files.
174 Utility yaz_iconv now supports conversion to MARC-8.
176 New facilities for the MARC module. The reading - and writing of
177 content are separate methods for the yaz_marc_t handle. The following
178 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
179 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
180 format). Write functions have prefix yaz_marc_write_.. The existing
181 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
182 available. Removed support for OAI-MARC and simplexml (not the
183 simplexml from PHP5).
185 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
186 to be returned for this connection.
188 --- 2.1.16 2006/03/31
190 Allow multiple languages and charsets to be specified with
191 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
192 negcharset iso-8859-1,utf-8
194 Translation of proximity nodes from CQL into PQF now works.
196 Moved to automake 1.8, 1.9.
198 Added function yaz_log_set_handler which allows a log handler to be
199 installed. This handler will be called for all log messages. Output
200 to file is also produced; but that can be disabled by passing NULL
201 fname to yaz_log_init_file.
203 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
205 For SRW (including GFS), accept application/soap+xml as content-type
208 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
209 produces NO stylesheet reference even if a default stylesheet is specified
212 --- 2.1.14 2006/03/14
214 Updated Windows package to include yazd.dll + yazd.lib for the
215 Development component.
217 If the environment variable YAZ_LOG is set, then it is used as a
218 string indicating the default level of logging to use if not
219 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
220 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
221 used as before. So, for example, to omit warnings from YAZ logging,
224 cql_transform() now map structure and other attributes before indexes,
225 so that index-specific structures and other attributes can override
226 defaults. So now a combination of mapping specifications such as:
228 index.dc.date = 1=date-modified 4=5
229 does the right thing.
231 cql_transform() now also respects the "always" mapping specification,
232 which establishes an initial set of attributes to be used for all
233 terms except where overridden by more specific attributes associated
234 with the index, relation or modifier.
236 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
237 which mode to use; one of "post", "get" or "soap" (SRW, default).
239 Fixes for yaz_iconv routines: changed trie-based character set conversions
240 to use only non-negative values for bit fields due to Sun's C compiler not
241 supporting negative values.
243 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
244 sequences where not read correctly. Fix by Rustam Usmanov.
246 Updated win/makefile to use options, settings which makes things
247 compile with VS C 2005.
249 --- 2.1.12 2006/02/01
251 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
253 In ZOOM socket code, use select instead of poll on MacOSX.
255 ZOOM-C now support client-side compilation of CQL into RPN that is
256 sent to the server, enabling CQL to be used against all Z39.50
257 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
258 ZOOM_query object, and submit it using ZOOM_connection_search().
259 The CQL-to-RPN translation uses a configuration file, the name of
260 which must be specified in the Connection's "cqlfile" option.
262 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
263 function, which takes as its start-term parameter a ZOOM_query object
264 (which may have had either CQL or RPN set into it).
267 --- 2.1.10 2005/11/29
269 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
270 GFS to support this as well. Backend handler, bend_srw_update, does the
271 update work. Code contributed by Ko van der Sloot.
273 Allow retrieval of Search Result-1 information in ZOOM by the use of
274 options that are attached to a result set. ZOOM documentation updated
277 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
278 UTF-8 conversion. Patch by Raj Patel.
280 Added option -m to GFS to control formatting of timestamps in log file.
282 Added 'exit' as synonym for 'quit' in yaz-client
284 Added support for specifying SRW resultSetId + resultSetIdleTime in a
285 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
286 for the new members. Patch by Ko van der Sloot.
288 Added support for SRU POST. It is supported for content-type
289 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
291 Do not build the separate Multi-threaded (MT) library libyazthread.la.
292 Instead make the library libyaz.la multi-threaded. Threading as a whole
293 can still be disabled by configure option --disable-threads. Previosly,
294 with older GLIBCs there were problems with MT libs under Apache. This
295 has now been fixed a long time ago.
297 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
300 CQL module modified to be case insensitive for relations/indexes/operations.
302 Fixed bug in CQL transform code: incorrect value relationModifieder
305 Added 'show all' command for yaz-client which retrieves all results
308 Added new yaz-client, xmles, which takes a (private) OID and
309 a document to be sent as an extended service request.
311 Describe new yaz-client commands wait_response and set_auto_wait.
313 Increase TCP/IP listener backlog from 3 (which I am guessing was
314 copied from the SunOS manual entry way back when) so SOMAXCONN, so
315 that the socket will queue as many incoming connections as it's able
316 to handle ongoing connections. In other words, it will never now
317 refuse a connection that it would be able to handle merely because
318 it's not got around to accepting() enough of the pending connections
319 yet. This is the behaviour anyway under Linux, where the listen()
320 argument is ignored; but not under BSD and on systems such as
321 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
322 YAZ-based servers should now be uniform across operating systems in
325 yaz-marcdump uses 64-bit file access on some systems. This is enabled
326 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
327 This allows yaz-marcdump to read large MARC batches (>2 GB).
329 Modified all YAZ source files - except the source which is auto-generated
330 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
333 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
334 corresponding to the existing *_setl() function. These allow option
335 values containing arbitrary valuues.
337 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
338 ZOOM_resultset_sort() in new applications. Its behaviour is identical
339 except that it returns an indicator of whether or not the sort
340 criterion was accepted (0 for OK, -1 for invalid).
344 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
345 MARC output rather than returning "new" buffer.
347 yaz-client warns about unknown init options.
349 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
353 Added support for SRW sort in Generic Frontend Server. Patch
354 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
355 sortKeys - or NULL if none is provided.
357 Fixed bug #307: It was impossible to specify indefinite/no timeout
358 for ZOOM_event. Special timeout value -1 now means indefinite timeout
361 Added support for multiple languages and charsets to be specified in
362 ZOOM. Each charset/language is separated by a blank. If negotiation is
363 in effect in init-response, Option
364 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
365 Code based on patch by Vasiliy Osadchuk.
367 Fixed bug #306: infinite recursion that occurred when calling
368 yaz_log_level_init as the first call (before other log level or
371 Fixed bug in scan handling in front end server: if preferred-Position-In-
372 Response was non-present, a NULL pointer referece was performed.
376 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
377 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
378 now defined for all those error codes. So instead of putting 109 in
379 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
380 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
382 Modified the yaz-marcdump utility to skip garbage bytes between MARC
385 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
387 Program yaz-client now exits and produces an error message if multiple
388 Z39.50 servers are specified on the command line (none or one allowed
391 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
396 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
398 Fixed bug #272: Preserve spacing for CCL terms.
402 Added support for virtual hosts and multiple backend servers for
403 the YAZ frontend server. The configution is XML based and
404 support specificition of CQL to RPN mappings and explain information.
405 See section "Virtual Hosts" in the YAZ manual.
407 Extended OPAC display utility. OPAC display utility renders
408 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
409 to supplement yaz_marc_decode_wrbuf.
411 Fixed a bug in MARC decoder that could caused it to crash for some
412 invalid MARC records. More diagnostics and warnings where added in
413 XML output (warnings, etc are stored in comments).
415 --- 2.0.34 2005/02/08
417 Fixes for UNIX domain sockets. Bug #261.
419 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
421 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
422 Added yaz_marc_subfield_str which defines subfield lead string which is
423 used in YAZ_MARC_LINE format. Default string is blank+$. Added
424 yaz_marc_endline_str which defines end of fields string used in
425 YAZ_MARC_LINE format. Default string is newline.
427 Experimental support for MarcXChange. This format can be produced
428 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
429 http://www.bs.dk/standards/MarcXchange.xsd
431 Added yaz-client commands scansize that sets maximum number of
432 entries to be returned by scan.
434 --- 2.0.32 2005/01/11
436 Added support for SRW scan in yaz-client and Generic Frontend Server.
438 * Added whereInList member to SRW Scan Term.
440 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
442 Fixed NMEM system to return aligned blocks on the smallest boundaries
443 that are suitably aligned for all possible types on the particular
444 architecture YAZ is being built for.
446 --- 2.0.30 2005/01/04
448 Fixed numerious warnings that was issued with newer versions of GCC.
450 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
451 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
454 Make YAZ Generic Frontend Server slightly faster.
456 Enhance (and reduce) logging for Generic Frontend Server.
458 Revert YAZ log system so that it flushes every write operation
459 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
461 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
462 instead of LOG_, due to name clash with syslog(3). LOG_ are still
463 present. New applications should define YAZ_USE_NEW_LOG=1 - this
464 will effectively disable old definitions.
466 --- 2.0.28 2004/11/09
468 Added yaz_log_time_format which specifies log format using
471 Added yaz_log_module_level which returns mask for a module. Value
472 is non-zero mask a if module is enabled; zero if disabled.
474 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
475 in include/yaz/cql.h.
477 Fixed bug #176: Dont throw diagnostics on empty SRU args.
479 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
481 Fixed bug #172: RPM builds does not enable SSL.
483 Doxyfile.in part of dist. Doxyfile generated by configure.
485 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
486 are given and the corresponding component does not exist.
488 Extend CCL documentation in YAZ reference. Describe r=r.
490 --- 2.0.26 2004/10/01
492 Fixed MARC->MARCXML conversion to properly deal with
493 fields, subfields, indicators having non-ASCII characters.
495 Fixed MARC->MARCXML conversion so that ASCII control characters
496 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
499 Added YAZ GFS support for conversion from Z39.50 surrogate
500 diagnostics to SRW surrogate diagnostics.
502 Bug fix: YAZ GFS did not return schema in explainResponse.
504 --- 2.0.25 2004/09/30
506 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
507 now converts recordSchema to elementSetName as well as schema URI.
509 Fixed bug in COMSTACK that prevented HTTP request packages from being
512 --- 2.0.24 2004/09/29
514 Added CCL facility r=r "range" which is similar to r=o "ordered" but
515 does not require white-space before and after the dash in a range, e.g.
516 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
519 Fixed a few AC_TRY_LINK configure tests that did not operate properly
520 due to new GCC removing "redundant" code.
522 Added yaz-client commands scanpos and scanstep that sets preferred
523 position and step-size for scan.
525 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
527 Added CCL utility ccl_qual_buf which parses one or more CCL
528 spec lines in a buffer.
530 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
531 of name and value - ignoring empty lines and comments.
533 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
535 Added odr_get_element_path which returns current element path for an
536 ODR handle. This utility is useful in error handling or user-defined
539 Added ODR_PRINT utility odr_set_stream which is is a more generic
540 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
541 to a write function and pointer to close function. The close function - if
542 non-NULL - will be called during odr_destroy.
544 Fixed bug in CCL parser where truncation char was not removed from
545 right side when truncation=both was in effect.
547 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
550 --- 2.0.23 2004/08/11
552 Fix buffer overrun in CQL parser when dealing with proximity (%).
554 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
555 to UTF-8/UCS conversion is now only based on codetables.xml.
557 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
559 --- 2.0.22 2004/08/06
561 Add support for more "commit changes" in ZOOM (uses Extended Services).
563 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
566 Yet another small fix for configure of SSL.
568 --- 2.0.21 2004/05/14
570 Fix SSL libs for configure when --with-openssl=DIR is given.
572 --- 2.0.20 2004/05/10
574 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
576 SSL comstack now uses yaz.pem certificate file on server side
577 by default. Certificate filename can be configured by calling
578 comstack function cs_set_ssl_certificate_file before cs_bind is used.
580 Fix bug regarding multiple calls to ZOOM_connection_connect.
582 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
584 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
585 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
587 ZOOM now allows inspection of X509 peer certificate for verification.
588 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
590 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
591 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
592 as "modular" but it simplifies things.
594 Added cs_get_peer_certificate to that returns peer X509 PEM.
596 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
597 NULL if SSL is unavailable.
599 Documentation about MARC decoding tools.
601 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
603 --- 2.0.19 2004/03/30
605 Rename CHANGELOG to NEWS to follow GNU style packing.
607 Fix bug with missing initialization of member in init_diagnostics.
608 This bug affects threaded version of GFS server.
610 --- 2.0.18 2004/03/20
612 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
615 Ensure zlib.dll is packed with Windows install.
617 --- 2.0.17 2004/03/17
619 Fix encoding of xsd:string to use text instead of CDATA.
621 Fix endless loop in CQL parser with unbalanced ".
623 Use a more compact way to store MARC-8 conversion tables.
625 --- 2.0.16 2004/03/16 Debian only
627 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
630 Update CQL parser to use new CQL 1.1 modifiers for booleans and
635 --- 2.0.15 2004/03/01
637 Another fix for decoding of XML packed records.
639 --- 2.0.14 2004/02/25
641 Fixes for Chunked encoding. White space not ignored after length spec.
643 Update NS and use default NS for SRW diagnostic elements.
645 --- 2.0.13 2004/02/23
647 Implement ZOOM_resultset_cache_reset which resets record cache.
649 Implement ZOOM_resultset_sort which sorts a result set.
651 Implement chunked HTTP transfer.
653 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
655 --- 2.0.12 2004/02/16
657 Added member 'schema' to bend_explain_rr structure so that backend
658 can specify explain record identifier. Defaults to Zeerex 2.0.
660 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
662 --- 2.0.11 2004/02/16
664 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
667 Added init command for yaz-client which sends "extra" init request.
669 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
670 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
672 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
674 Make ZOOM error code for "invalid query".
676 Fixed compilation for SSL which wasn't properly enabled for all platforms.
678 --- 2.0.10 2004/02/05
680 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
683 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
685 Added option -p <file> to make Generic Frontend Server to write PID file.
687 Added option -D to put Generic Frontend Server in background on its own.
689 Make ZOOM C recognize option "password". If unset, "pass" is used
690 (for backwards compatibility).
692 Fixed a bug in Generic Frontend Server that could make it crash if a
693 client sets characterSetNegotation bit, but didn't pass negotiation stuff
696 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
697 Must be issued before open, in order to be in effect.
699 --- 2.0.9-6 2004/01/12 Debian/Windows
701 Make the SRU server more picky WRT unknown params, etc.
703 Bug fix: ZOOM scan response didn't return displayTerm - when present.
705 New YAZ client command, options, that sets Z39.50 options.
707 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
708 options from a string of tokens (one token for each option bit).
710 Update SRW diagnostic code messages.
712 --- 2.0.9-5 2004/01/07 Debian/Windows
714 Handle user defined stylesheet for SRW/SRU.
716 --- 2.0.9-4 2004/01/06 Debian/Windows
718 Fix bug in decoding of Content-Length.
720 --- 2.0.9-3 2004/01/06 Debian/Windows
722 Fix a bug with decoding of XML packed records.
724 --- 2.0.9-2 2004/01/05 Debian only
726 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
728 Fix bug in SRW/SRU diagnostics decoding.
732 Fixed bug in Generic Frontend Server which could drop records exceeding
733 preferred message size. Reported and fixed by Irina Dijour.
735 Fixed calculation of package size for structured records in Generic
736 Frontend Server. Reported and fixed by Irina Dijour.
738 Fixed namespace for SRW/SRU diagnostics.
740 Fixed SEGV in yaz-client that occured for HTTP connection errors.
744 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
745 this version is incompatible with version 1.0 and older YAZ SRW/SRU
748 CQL changes to reflect recent changes to the specification:
749 * Documentation talks about context sets instead of index sets.
750 * Documentation talks about indexes instead of qualifiers.
751 * The CQL-to-PQF transformer's configuration file now uses
752 "index.set.name = <attributes>" instead of the old form
753 "qualifier.set.name = <attributes>". (Both forms are still
754 understood but the latter is deprecated.)
755 * CQL terms with no explicit index specified are now interpreted as
756 cql.serverChoice instead of srw.serverChoice (which of course
757 behaves exactly the same.)
761 MARC conversion can now generate ISO2709 output in another
762 character set. yaz-marcdump uses this facility if you invoke it
765 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
766 functions from there can be used from C++.
770 Frontend server now transfers memory from decoded packages to stream
773 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
774 references to show up.
776 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
777 the ZOOM Abstract API. The older names for the same options are still
778 also supported for the benefit of old applications.
780 ZOOM-C supports "implementationId" and "implementationVersion" options
781 to go along with "implementationName". These allow the user code to
782 specify identification strings to be sent to servers.
783 Add OID for the new ExtLite attribute set.
785 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
786 as requested/supplid by Ere Maijala <ere@atp.fi>
788 For generic frontend server, reverse the order of
789 "toolkit-supplied / application-supplied" strings sent as implementationId,
790 Name and Version. Also, remove the spaces around the slash. This brings
791 the GFS in line with the behaviour of ZOOM-C on the client side.
793 Add function ZOOM_scanset_display_term.
795 yaz-client shows scan displayTerm if present.
797 Utility yaz-iconv is now installed by default along with the man page
800 Extend configure check for OpenSSL to use pkg-config where available (such
803 Incorporate patch by Morten Bogeskov which allows a Unix file socket
804 server to specify uid/gid/mask for socket using the format
805 unix:[user=uid,][group=gid,][umask=mask,]file=path
806 If file= is omitted the existing format is assumed, e.g.
808 in which case the mask is 0666 (rw for everybody).
810 Major restructure of YAZ source. All source in libyaz is in src directory.
811 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
812 util (utility programs such as ASN.1 compiler, yaz-marcdump).
814 Added man page for utility yaz-marcdump (used to be called marcdump).
815 yaz-marcdump is installed by 'make install'.
817 Fixed a memory leak in Generic Frontend Server that occurred when decoding
818 of incoming package failed.
820 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
822 Change prototype of odr_perror: add const to message string.
824 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
826 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
827 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
828 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
829 DNS lookup. There should not be any compatibility problems with this
830 assuming that blocking=1 or 0 is used.
832 Fix bad reference in UNIX comstack in function cs_addrstr.
834 Fix for compilation on AIX.
836 The generic front-end server (server/seshigh.c) now supports returning
837 Init diagnostics to the client in User-information-field, in
838 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
843 Allow any CQL relation (not just all,any,exact,scr).
845 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
846 that features the same UI.
848 Implemented command update0 in YAZ client which is equivalent to
849 update but uses old of Ext Update ASN.1.
851 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
852 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
853 Previously no OID was used for this info.
855 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
856 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
857 returns 'malformed search term' otherwise.
859 SortResponse member resultCount now set to NULL in sort handler of
862 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
865 Add three new utility functions for translating OIDs between various
866 formats -- symbolic name such as "Usmarc", minus-1-terminated int
867 arrays and dotted strings such as "1.2.840.10003.9.5.1":
868 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
869 char *oid_to_dotstring(const int *oid, char *oidbuf);
870 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
872 Reverted modifications for ES Update definition for z_IU0Update
873 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
874 is back to YAZ 2.0.2.
876 String value attributes for CCL parser.
878 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
879 which their FirstSearch server returns in Init responses, sometimes
880 carrying useful diagnostic information when Init fails. This has the
881 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
882 "z39.50/oclcui.asn", where its definition is somewhat different from
883 what OCLC document on their web-site, as required to interoperate with
886 Support for anonymous authentication in yaz-client. Use the command
889 * Fix the OID of the Index Data-local "admin" Extended Service from
890 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
891 the 1000, which indicates a locally-defined OID, was a mistake.
895 Fix CCL directive @case handling so that it affects string match for
896 both CCL keywords and qualifiers.
898 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
899 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
900 Decoder has been updated with ASN.1 changes as listed in
901 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
902 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
903 z_IUUpdate, remains unchanged.
905 ZOOM_record_get may now return a record in a specific character set.
906 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
907 "from" is the character set of record as returned by target. "to" is
908 the character set to be returned. If omitted, "to" is UTF-8.
910 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
912 New ODR utility, odr_getelement, which returns name of element for
913 which encoding/decoding failed.
915 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
916 in cases where a required element was omitted.
918 Bug fix: some MARC8 sequences were not converted.
920 New ZOOM option "step" which specifies number of records to be
921 retrieved in one chunk. Used in conjunction with "start" and "count".
923 SRW support for yaz-client. Use scheme http: to use it, e.g.
926 yaz-client no longer does (un)intelligent character set conversions
927 by default. Can be enabled with charset and marc_charset commands.
929 xmalloc trace fix for 64-bit systems such as DEC alpha.
931 Solaris 2.6 compile fix.
933 New function, cql_strerror() translates SRW error codes, as returned
934 by cql_transform_error(), into human-readable English strings. Used
935 in yaz-client diagnostics when appropriate.
937 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
938 converts it into a type-1 query which is sent to the server. This
939 makes CQL available for use with all Z-servers, as opposed to the tiny
940 minority that can handle CQL queries themselves.
944 New Debian package layout similar to the Redhat Package layout.
946 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
947 and search result respectively.
951 Redhat package is now several packages: libyaz (runtime libraries),
952 libyaz-devel (development and documentation, and yaz (utility programs).
953 Package spec file by Morten Bøgeskov.
955 New member 'schema' in struct bend_fetch_rr which the name of requested
956 schema (SRW/SRU) for record (or NULL if none was given). The fetch
957 handler MAY set this to reflect the schema of the returned record.
959 New member 'display_term' in struct scan_entry. GFS now sets member entries
960 and allocates scan entries to be filled by user scan handler. In previous
961 version, entries member was allocated by the scan handler. That still works,
962 but the GFS will ignore member display_term - assuming it was NOT set by
963 the handler. The fact that the GFS now allocates the entries both allows
964 for new members and makes a scan handler easier to write.
966 Fix CQL lex buffer overflow.
968 SRW/SRU recordPacking. For SRW default recordPacking is string. For
969 SRU default recordPacking is string.
971 SRU protocol support for frontend server.
973 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
975 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
977 Added scan for the ZOOM shell (zoomsh).
981 * String Identifers for Schemas (Amendment 5).
982 http://lcweb.loc.gov/z3950/agency/amend/am5.html
983 Old definition for schema
984 Odr_oid *schema; /* OPT */
989 Z_InternationalString *uri;
990 #define Z_Schema_oid 1
991 #define Z_Schema_uri 2
994 * resultCount parameter to Sort Response (Amendment 1).
995 http://lcweb.loc.gov/z3950/agency/amend/am1.html
997 Support for SRW 1.0 over HTTP. This is an optional feature and
998 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1001 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1002 on the same port. SRW SearchRetrieveRequests are mapped
1003 to bend_init,bend_search,bend_fetch,bend_close.
1005 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1007 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1008 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1010 ZOOM connections are SRW based if schem http is used for hostname
1011 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1012 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1014 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1015 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1016 distance=n, order=true/false, relation=le, prox unit=word. If
1017 n is omitted, distance 1 is used.
1019 Fixed problem with C compiler include path in wrong order.
1021 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1022 on Solaris. Patch from Ko van der Sloot.
1024 New MARC decode API. All new functions operate on a yaz_marc_t
1025 handle. The most important new functions are: yaz_marc_create,
1026 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1027 decode and destroy respectively. Decoder can produce formats
1028 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1029 include/yaz/marcdisp.h.
1031 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1032 to UTF-8, UCS-32, wchar_t or Latin-1.
1034 * Prototypes for yaz_iconv_-functions moved to separate header
1035 include/yaz/yaz-iconv.h.
1037 Make a few private functions 'static' in unix.c. This prevents
1038 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1040 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1041 are set when Init Response is received.
1043 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1044 but returns diagnostic set as well.
1046 New function yaz_strerror which is a portable wrapper for
1047 strerror/strerror_r/GetLastMessage.
1049 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1050 is returned for MARC. If type is "oai", then OAI MARC is returned.
1052 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1055 --- 1.9.2 2002/11/26
1057 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1059 Fix bad race conditions on SIGTERM and terminate gracefully in
1062 Move retrieval (data1) module to Zebra since nobody seems to be
1065 Add GRS-1 render for ZOOM using same format as yaz-client.
1067 --- 1.9.1 2002/10/05
1069 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1071 Fix broken ESpec handling in data1 module.
1073 SGML reader parses comments and makes them part of the data1 tree.
1075 Added several type casts so that YAZ compiles as C++ code.
1077 ZOOM didn't handle PDU encoding failures properly.
1079 Added more Bib-1 diagnostics (approved extensions).
1081 GNU configure: better check for iconv.
1083 More portable use of accept, getpeername. Check for socklen_t. Use
1084 int/size_t if socklen_t is not defined.
1088 PQF parser rejects bad queries - including those with extra
1089 characters in them. PQF parser used to silently ignore that.
1090 Cleaner API for PQF added, which allows you to get detailed
1091 error information for bad queries (see yaz/pquery.h).
1093 Fixed bug in ZOOM_record_get for type "database".
1095 Implemented mini iconv library supporting conversions between
1096 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1098 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1100 --- 1.8.9 2002/08/20
1102 Fixed ZOOM C record cache so that preferredRecordSyntax and
1103 elementSetName is used to check for already fetched records.
1105 --- 1.8.8 2002/08/02
1107 Added three members in bend_initrequest structure to facilitate
1108 character set negotiation.
1110 Fixed a bug in frontend server that could cause indefinite
1111 loops under rare conditions.
1113 Revised character set utilities (charneg.h) so that encoding
1114 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1116 For PQF, directive @term <type> sets term type for Scan/Search.
1117 Here <type> is general, string, numeric, null. The term type
1118 is inherited - just like @attr.
1120 New call odr_set_charset that sets character set conversion for
1121 international-strings on a ODR stream. Prototype is:
1122 int odr_set_charset(ODR o, const char *to, const char *from);
1123 The InternationalString is still represented as C string in YAZ
1124 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1125 won't). On the protocol level, you can use any encoding.
1127 Support for UNIX sockets in ZOOM.
1129 Solaris recv sometimes returns errno == ENOENT. It is treated as
1130 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1132 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1133 both client and server. Code by Morten Bøgeskov.
1135 --- 1.8.7 2002/05/22
1137 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1138 that they can be used directly from Visual Basic. You must recompile
1139 your windows APP if you're using ZOOM.
1141 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1142 Commands "lang" and "charset" sets language and character set respectively.
1143 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1144 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1146 Attributes from multiple CCL fields may be OR'ed rather than merged
1147 using directive "@field or". Fields are still merged by default -
1148 equivalent to "@field merge".
1150 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1153 Fixed bug in zget for parameter ExtendedServicesResponse.
1157 --- 1.8.6 2002/03/25
1159 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1161 Client displays USR.1:SearchResult-1 (hits per term).
1163 Additional Search Info for search in Generic Frontend Server.
1165 Fixed CCL parsing of "field=s".
1167 WIN32 installer - using the excellent NSIS software from nullsoft.
1169 Fixed CCL parsing of "field = - <number>".
1171 Added function yaz_marc_decode that decodes MARC for line mode
1172 display or XML (similar to that used by JZKit).
1174 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1175 Z39.50. But ISO/ILL was, however.
1177 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1178 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1180 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1181 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1183 --- 1.8.5 2002/02/03
1185 New YAZ client features: Command completion and new commands:
1186 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1187 Code provided by Jacob Poulsen.
1189 New call oid_trav, that visits all registered OIDs via callback.
1191 Function ZOOM_record_get now returns const char pointer rather than
1192 void pointer. It saves a lot of type casts.
1194 For YAZ client, command "auth" now allows you to set authentication
1195 in IdPass style. It is enabled when three tokens are given - order
1196 is user, group and password.
1198 Fix memory leaks in MARC record handling for ZOOM.
1200 New option for YAZ client, -k <kilobytes> that sets
1201 maximum record size. Similar to -k option for generic frontend
1202 server and yaz-ztest.
1204 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1206 Prefix query parser reports "fail" when bad attribute set is given.
1208 Fix in MARC decoder. Proximity logging. Fix for attribute set
1209 in scan handler for server. Patches by Shigeru Ishida.
1211 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1214 Configure option --with-openssl=<dir> now works when a directory is
1215 specified. Patch provided by Morten Bøgeskov.
1217 New option for YAZ client, -u <auth>, that sets authentication.
1219 ZOOM fix: error information was sometimes "missing", since error
1220 was cleared/reset too when it shouldn't.
1222 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1224 --- 1.8.4 2002/01/04
1226 Scan for ZOOM API. New object ZOOM_scanset. New functions
1227 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1228 ZOOM_scanset_destroy.
1230 New ZOOM function, ZOOM_connection_last_event, that returns type
1231 of last event (such as "receive data", "send data", "apdu received",
1234 New ZOOM option, schema, that specifies schema for retrieval.
1236 New CCL feature. Qualifiers can be aliases for one or more
1237 other qualifiers (if more than one is given, OR is used).
1239 ZOOM uses named result sets if target supports it.
1241 Two new YAZ client commands: . (dot, which sources a script of YAZ
1242 client commands), and ! (to execute shell command.). Implemented
1245 Working on Debian packages.
1247 --- 1.8.3 2001/11/19
1249 YAZ client enables named result sets only if target supports it.
1251 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1253 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1254 with key="host" to get same result.
1256 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1257 Function Z3950_resultset_record(s) returns references to records
1258 "owned" by resultset. To become owner use Z3950_record_clone.
1260 Function z_ext_record handles Extended Services. Thanks to
1263 --- 1.8.2 2001/11/12
1265 CCL Parser fix: ignore token comma when dealing with and-lists.
1267 Documentation updates for COMSTACK.
1269 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1270 Changed prototype Z3950_records. For some functions, int parameters
1271 were changed to size_t.
1273 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1276 New MARC decode/display function, marc_display_exl, which properly rejects
1277 non-ISO2709 records. YAZ client uses it.
1279 --- 1.8.1 2001/10/29
1281 Fix bug: local attribute set wasn't set correctly in PQF strings.
1285 * Old Z39.50 codecs no longer supported.
1287 Added ZOOM C binding. See http://zoom.z3950.org/
1289 Renamed states for COMSTACKs to avoid confusion with events.
1291 Implemented cs_look and proper cs_rcvconnect.
1293 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1295 Configure detects POSIX threads on OpenBSD.
1297 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1298 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1300 When error is returned from present handler, non-surrogate diagnostic
1301 is returned in present response (and fetch handler is no longer called).
1303 * Minor adjustments to pquery parser (PQF). Token characters may be
1304 escaped by using backslash (C-style).
1306 PQF parser allows string attribute values to be specified. For @attr,
1307 non-numeric characters after the equal-sign are treated as strings
1308 (e.g. @attr 9=title).
1310 CCL trunction character may be defined (@truncation in file)
1312 * function zget_ExtendedServicesRequest sets waitAction to
1313 waitIfPossible (was wait).
1315 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1318 CCL operator names may be set in field definition files (CCL_bibset).
1319 See ccl/bib1 for an example.
1321 Fixes in ASN.1 compiler for C++ compatibility.
1323 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1324 and "op_or" to avoid conflict with C++.
1326 Fixed problem with GNU readline detection on Redhat 7.0.
1328 Added step-size for Scan backend handler.
1330 Fixed bug that made the frontend server crash when no attribute
1331 set was specified for scan.
1333 Front-end server automatically switches to original working directory
1334 when installed as an NT service. Previously -w had to be specified to
1337 Added extended attributes for retrieval module (data1), so that data1
1338 records carry d1_readXML/SGML attributes. d1_read also supports
1339 null-data rules ( <tag/>)
1341 On UNIX when POSIX threads are available, a separate library libyazthread
1342 is created. Programmers should link with that library and the yaz library
1343 when using threads. The reason for the split was that some applications
1344 on Linux, such as Apache, doesn't work well when using shared objects that
1347 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1348 (or any frontend server) in SSL mode by specifying ssl: followed by
1349 address. Only tested on UNIX.
1351 Added feature for CCL module. Virtual structure s=al or s=ol generates
1352 and-list and or-list respectively instead of phrase search.
1356 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1357 log_mask_str. This was done to avoid name conflicts with other libraries
1358 (such as other PHP extensions).
1360 Added raw OID member for preferred record syntax (request_format_raw)
1361 and returned record syntax (output_format_raw) for backend fetch method.
1363 Config file yaz-config now accepts options so that it returns specific
1364 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1366 Shared library support for UNIX using GNU libtool.
1368 * Modified backend interface. Request/Response struct's replaced by
1369 one read/write C struct. For example bend_fetchrequest and
1370 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1371 Every handler - even search has to be registered in bend_init
1372 handler. This means that the YAZ library no longer refers to
1373 external functions and it makes it possible to make the whole
1374 thing a single DLL/SO.
1376 Added Segment handler for backend server.
1378 Added Zmbol/Zebra administrative functions to YAZ client.
1380 Threaded frontend server on UNIX (when POSIX Threads are available).
1381 Starting the server with option -T enables multi-threading.
1385 Added configure option --enable-comp/disable-comp to control use
1386 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1387 located in sub directory asn.
1389 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1390 in ${exec_prefix}/bin along with the other programs yaz-client and
1393 GNU automake used to maintain makefiles.
1395 Added several OID's.
1397 Changed retrieval module so that we can load records with no abstract
1398 syntax defined. Tagpaths in these records are fully composed of string
1401 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1405 On UNIX, the generated makefile now supports a proper 'make install'.
1406 The prefix can be set via GNU configure to set the install location
1407 (default is /usr/local).
1409 * YAZ programs client and ztest were renamed to yaz-client and
1410 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1411 locations, such as /usr/bin,/usr/local/bin,etc.
1413 * YAZ Header files were moved from include to include/yaz. YAZ Header
1414 files are referred to as include <yaz/log.h> rather than <log.h>.
1415 The YAZ include path (-I ..) is therefore the same as before. Programmers
1416 should update their #include statements or use -Ipath/include/yaz
1417 instead. The main motivation for doing this change is that YAZ header files
1418 can be installed in "standard" locations /usr/include,/usr/local/include
1419 without introducing conflicts, since ALL YAZ header files are stored
1420 in subdirectory yaz (under /usr/include for example).
1422 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1423 rather than project/workspace files. We switched because project files
1424 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1427 Changed name of logging function, logf, to yaz_log, to prevent name
1428 clash with some math-log functions. The YAZ header log.h defines logf
1429 to yaz_log (#define) so there should be no incompatibilities by this
1432 Added bend_start/bend_stop handlers for server. These handler are
1433 called on start/stop of server. For windows they are called whenever
1434 a service is started/stopped.
1436 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1437 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1438 in util/yc.tcl. The auto-generated C code structures are, in a few
1439 cases, incompatible with the old decoders. There are differences in the
1440 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1441 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1442 The preprocessor variable ASN_COMPILED is defined when the compiled
1443 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1444 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1445 wish to use the old encoders/decoders you can specify --disable-yc
1448 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1449 version so that it supports both new - and old version of DB Update
1451 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1452 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1453 change. The name parameter can be set to 0 in which no name is specified
1454 for the construction. The macros odr_implicit and odr_explicit sets name
1455 parameter to zero for the construction involved. New macros
1456 odr_implicit_tag and odr_explicit_tag are similar to the others,
1457 except that a name parameter is added. For programmers' that don't use
1458 ODR they probably only need to change the call to z_APDU and z_External.
1460 Added access control facility by interfacing the TCP wrapper library.
1461 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1462 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1463 name of the daemon and enables the access control as specified in
1464 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1466 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1467 den Dool <H.M.vdnDool@kub.nl>.
1469 Added reference ID parameter to most functions in server API - refer
1470 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1472 Changed name of ccl library to libccl.a (was ccl.a).
1474 Fixed bug in decoder for Explain (Category TargetInfo).
1476 Added support for GNU readline in client. Thanks to Jacob Poulsen
1477 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1479 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1480 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1481 IMPLEMENTATION! This change was made to the development version before
1482 the ZIG decided to retract the amendment. If any users MUST be
1483 compatible with the original Update definition, PLEASE CONTACT US, and
1484 we will include a separate definition corresponding to the old Update
1485 ES. Note that because of the change to the ASN.1 of the
1486 TaskPackageRecordStructure we cannot define a single structure that
1487 will support both versions.
1489 * Added const modifier to buffer parameter for some ODR/BER encoding
1490 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1491 completeWAIS, odr_dumpBER.
1493 Fixed bug in client.c which caused a crash when a scanResponse didn't
1494 contain positionOfTerm.
1496 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1497 * will cause an error in a client if a non-YAZ target sends both a
1498 * list of Scan entries and non-surrogate diagnostics.
1500 Retrieval module enhancements. Tag sets may be typed in the reference
1501 to it. From the .abs-file the "tagset" directive takes a third optional
1502 integer type for the tag set referenced. From a .tag-file the "include"
1503 directive takes a third optional type as well. The old "type" directive
1504 in the tag set itself is still recognized but acts as the default type
1507 Backend interface change. Individual Scan terms returned from bend_scan
1508 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1509 in include/backend.h.
1511 Retrieval module enhancements. Multiple tag sets and attribute sets may
1512 be specified in abstract syntax specs. Revised the error/warning for
1513 logging messages reported by the retrieval module when reading the
1516 Object Identifier system (oid_..) changed. The API is backwards
1517 compatible but the oid-routines now allocates new OID's when needed.
1518 Raw OID's may be specified in oid_getvalbyname.
1520 YAZ now uses GNU configure to generate Makefile(s).
1522 * Minor changes in some of the member names of DeleteResultSetRequest and
1523 DeleteResultSetResponse. See include/proto.h.
1525 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1526 and added member 'languages' in TargetInfo (which was missing).
1528 Changed the way attribute sets are handled in the retrieval
1529 module. These are now cached, just like the abstract syntaxes
1532 Changed YAZ so that it links with compiled ASN.1.
1534 Added Explain-schema definitions and mapping routines. The following
1535 Explain categories have been implemented: AttributeDetails,
1536 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1538 Fixed minor bug in Windows version of Server Library.
1540 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1542 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1544 Added EXTERNAL: UNIverse Resource Report (non-standard).
1546 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1547 ENUMERATED and SET OF.
1549 * Added 'const' to some of the char pointer arguments for the
1550 functions, data1_read_node, data1_getelementbytagname,
1551 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1554 Fixed bug in data1_insert_taggeddata - the last_child member of
1555 parent wasn't initialised.
1557 * Changed data1_read_record and data1_read_node so that the supplied
1558 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1559 doesn't refer to any parts of the "SGML"-buffer.
1561 Fixed bug in server library (Windows version of statserv_remove).
1563 * Changed code so that it compiles as C++. The type definition
1564 of Odr_fun which is a member of Odr_arm was changed. The result is,
1565 that an explicit typecast is needed for the fun pointer when
1566 using Odr_arm - as in:
1567 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1569 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1571 Implemented the new structured date and time definition as approved
1572 by the ZIG. Added schemaId element to the specificTag in Espec-1
1573 (also approved at the last ZIG). Thanks to RVDM.
1575 Added some Object identifiers (RVDM).
1577 Changed the Update Extended Service (RVDM).
1579 Added command "refid" to client which specifies referenceId for
1580 the following requests.
1582 Implemented extended service handling for server. See ztest.c
1583 for an example as well as backend.h. New handlers are registerd
1584 in the Init handler.
1586 * Changed interface for sort in server.
1588 Added new members to statserv_options_block. It allows a server
1589 to read options from another source than just the command line. Thanks
1590 to Charles Woodfield.
1592 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1593 renamed to zboolean. Some C++ compilers complained about the name.
1595 Minor changes to gils.abs. Added index 's' (sort) on title
1596 and date/time-last-modified.
1598 --- 1.4pl2 1998/1/30
1600 Fixed bug in server library regarding inetd mode (-i). This bug
1601 was introduced by release 1.4.
1603 --- 1.4pl1 1998/1/29
1605 Added sort facility in client and backend server interface.
1607 Fixed problem with dependencies in Makefile(s).
1609 Fixed bugs for encoders/decoders of extended services and
1612 Implemented sub-tree feature for schemas. Sub-trees are
1613 referenced in *.abs-files. See explain.abs for an example
1614 of the use of this feature.
1616 Modified bib1.att; local attributes for ANY didn't include
1617 ANY itself (only affects use of the retrieval module).
1619 Fixed bug in plain SGML reader in function data1_read_node:
1620 tags with prefix "var" was incorrectly interpreted as variants.
1622 Added feature "sub-schemas" to enable references to - and definitions
1623 of - group of elements.
1625 * Removed member parent from type data1_element (in data1.h).
1627 Implemented function odr_nullval() that returns the value of
1630 * Removed member num_children from data1_node (in data1.h).
1632 Made NT service interface part of the server library. The
1633 function statserv_main uses the NT service when required and
1634 calls the statserv_start / statserv_close routines.
1636 Routine zget_SearchRequest and zget_PresentRequest fills
1637 resultSetName/Id member with "default" instead of "Default".
1639 Fixed memory leak in server. Request queue member wasn't freed.
1641 Fixed nmem_exit so that memory is freed.
1645 Revised the CCL parser utility to be thread safe.
1647 Added function, oid_ent_to_oid, to replace the function
1648 oid_getoidbyent, which is not thread safe.
1650 * Added nmem_init and nmem_exit to initialize and release
1651 NMEM resources. Function nmem_init should be called once in the
1652 initial thread before NMEM/ODR is used. statserv.c and client.c
1653 have been changed accordingly. The change was necessary to make
1654 NMEM thread safe. The NMEM memory pool is shared amongst threads
1655 in a process. Unix-based applications will still work fine without
1658 Added NT Services interface for the the Z39.50 (statserv) Server.
1659 Refer to the ztest.c source on the usage.
1661 Windows 95/NT port using MSVC5.0. Project files are included in the
1664 * Defined new 'global' handle for the retrieval (data1) system. The
1665 new handled, data1_handle, describes the state of the data1 system.
1666 This handle is passed as first argument to virtually all
1667 data1 related routines. The functions data1_create and data1_destroy
1668 creates and destroys a data1 handle respectively.
1670 Added ODR encode stream member to all backend request structures
1671 init, search, scan etc. This stream should be used to allocate all
1672 memory used for the response when thread safe operation is needed.
1674 Changed the comstack utility, cs_addstr, to be thread safe. The
1675 returned hostname string returned by the function is now part the
1678 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1679 function. The cs_straddr takes a COMSTACK handle as argument, so this
1680 function must be used after cs_create and before bind/connect.
1681 This function is thread safe.
1683 Moved test server to 'ztest' directory - generic server code still
1684 in 'server' directory.
1686 Made prefix query (pquery.c) utility thread safe.
1688 Added new function modifier YAZ_EXPORT to 'export' public DLL
1689 functions when using windows (see include/yconfig.h).
1691 Added definitions to the OID database (util/oid.c) (RVDM).
1693 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1695 Added call to ccl_rpn_delete in client program.
1697 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1698 release of RPN structure.
1700 Added support for C++, headers uses extern "C" for public definitions.
1701 With input from RVDM.
1703 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1704 Thanks to Ronald van der Meer (RVDM).
1706 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1708 Added support for private extensions to the OID database
1709 (oid_setprivateoids()). Thanks to RVDM.
1711 Added optional, physical ANY (key replication)
1713 Fixed null-reference problem in GRS-1 output filter.
1715 Proximity operator added to Prefix Query Format (PQF).
1717 In test client command "base" accepts multiple databases.
1719 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1723 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1725 Smallish bug-fixes in the new encoders/decoders (explain).
1727 Bug fixed in DeleteRequest.
1729 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1731 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1733 Added SOIF syntax (using private OID for now) to retrieval module and client.
1735 Added Update extended service.
1737 Added SearchResult-1 additional info structure.
1739 Added optional CCL (ISO8777) interpreter as separate module. Available
1742 --- 1.2 1996/6/10 (1st anniversary release)
1744 Added Summary record syntax. Lightly tested.
1746 Added OPAC record syntax. Untested.
1748 Added ResourceReport service encoders/decoders. Untested.
1750 Fixed bug in z_Unit - wrong tagging on unitSystem.
1752 Fixed bug in the DiagRecs decoder.
1754 Added options for max PDU size and session timeout to frontend-server.
1756 Added documentation of query-language parsers and other supporting utilities.
1758 [frontend-server] Added Attribute set to the bend_scanrequest API.
1760 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1761 surrogate diagnostics were generated.
1763 [retrieval] Allow multiple local values for attribute.
1765 [retrieval] Allow multiple attributes per element in .abs files. index type.
1767 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1769 --- 1.1pl2 1996/4/10
1771 Minor changes, mostly specific to Zebra's requirements (retrieval)
1775 Repaired bug in frontend server when running multiple listening
1776 endpoints in dynamic mode.
1778 z_External() now won't break if a known, ASN.1 value comes encapsulated
1779 in an octet-string. The value will pass through unmodified in an Odr_oct.
1781 Added a bit of code to the demo client to decode & display
1782 ASN.1-structured records represented in the octet-aligned branch of
1783 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1785 Added z_ext_getentbyref() to the ASN module. Doc updated.
1787 * Completed the SCAN definition in the ASN module. This may break SCAN
1788 code based on older YAZ-versions at compile-time. The fix is easy -
1791 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1792 under the SCAN definition. Remember to initialize this, server-people.
1794 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1795 that this does not extend to ODR and ASN.
1797 Comstack allows insertion of established socket (primarily for
1798 inetd-operation of servers). Doc updated.
1800 Front-end server can now start from the inetd in TCP mode. Doc
1803 --- 1.0pl4 1996/1/24
1807 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1808 the rank and record number.
1810 Adjustments to the frontend server.
1812 Fixed diagnostic BER dumper. It ignored the file argument.
1816 Various changes to retrieval module.
1818 Changed the union discriminators of the protocol files from enums to
1819 ints paired with #defines.
1821 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1824 *Changed operator in the RPN structure to 'roperator', again to avoid a
1827 Fixed problems in Explain decoders/encoders.
1829 --- 1.0pl2 1995/12/6
1831 Memory bug in log module fixed.
1833 --- 1.0pl1 1995/12/5
1835 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1837 Bug in Explain DatabaseInfo module fixed.
1839 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1843 The shift to v1.0 signals that we now consider the *core* functionality
1844 of YAZ reasonably stable (the core being more or less equivalent to
1845 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1846 tested (Explain not at all - though that will happen soonish).
1848 Minor changes to code to support Windows port.
1850 Various minor changes after we're getting to use GRS-1 & co. more.
1852 Added Espec-1 format.
1854 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1855 of the protocol and it cannot be selected when encoding (maps into 'string'
1856 when decoding). Needed to talk to some servers.
1858 Demo client can request simple element set names.
1860 Added Diagnostic Format encoders/decoders.
1862 Added simple Close handling to frontend server (no hooks for resource
1863 reporting yet), and demonstration client.
1865 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1867 --- 1.0b3 1995/08/24
1869 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1870 handled incorrectly when records were requested in the searchResponse. This
1871 will only affect you if you use the frontend-server.
1873 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1874 Test-client will ask for and print GRS1. Ztest will return dummy records
1877 Added Explain encoders/decoders to the service-level API. Untested.
1879 Added Extended Services: Item Order encoders and decoders to the Service-
1880 level API. Untested. We could use a recent copy of the pertinent bits
1881 of the ILL protocol to add those bits.
1883 Added diagnostic format 1 encoders/decoders to the service-level API.
1886 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1887 odr_cons.c, which causes a more correct output.
1889 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1890 was always set to 0 when no records were requested in the searchRequest.
1892 * Added better external-handling. This shouldn't harm old code that
1893 *encodes* externals. It can break code that looks for a
1894 'single-ASN1-type' representation, since those types that are known
1895 are now decoded immediately. Look at the SUTRS sample code in
1896 seshigh.c and client.c. Documentation updated.
1898 Handling of structured records in bend_fetchresponse. Length -1 marks
1899 structured record, type is deduced from format field.
1901 --- 1.0b2 1995/06/27
1902 Fairly quick maintenance release to add SUTRS support.
1904 Fixed handling of SUTRS records in the demonstration client.
1906 * Added format field to the bend_fetchrequest and bend_fetchresponce
1907 structures of the backend API (frontend server). When the record is
1908 returned, the value of the format field is mapped to an OID. The
1909 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1910 of the record. The special value VAL_NONE in the bend_request means
1911 that no specific format was requested by the client. Documentation
1912 updated accordingly. Test server (ztest) will return a fixed dummy
