1 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2 does not print anything except warnings for records.
4 For yaz-marcdump, added support for MARC split into files (-s) with a given
7 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
8 spec, at http://www.loc.gov/standards/sru/record-update/
9 This has changed the binary layout of the following structs:
10 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
11 bend_update_rr . Patch by Ko van der Sloot.
13 Added GFS utility function bend_assoc_is_alive which returns 1 if
14 association is still alive (client is connected); 0 otherwise (client
15 closed connection). This allows busy servers to stop working for
18 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
19 been a separate piece of software. This version of ziffy has been modified
20 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
22 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
24 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
25 Client code may now interrogate options such as "init_opt_sort" to
26 find out whether the server claims to support various options.
30 Added utilities yaz_{set,get}_esn to set/get element set name from
33 Removed the build of libyazthread.la. The libyaz.so is the threaded version
34 of YAZ and has been so since YAZ 2.1.10.
36 Implemented ZOOM_record_error which returns error information for
37 record (surrogate diagnostic).
41 Updates for SRU Update by Ko van der Sloot:
42 1. Changed name from "operation" to "action"
43 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
44 versions in the code, marked as 'backward compatible'.
45 3. Added diagnostics for SRU Update.
47 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
49 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
51 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
53 For GFS, fixed problem with SRU diagnostic 'First record position out of
54 range' being issued for 0 hits.
56 zoomtst10 part of Windows Build.
60 Implemented yaz_filepath_comp which splits a path into file path
61 components (required by Zebra 2.0.3+).
63 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
64 BSD inspired license until now so this should not have any real impact on
65 anybody. See http://www.opensource.org/licenses/bsd-license.php
67 Fixed bug #687: Missing log lines.
69 Fixed bug #678: CQL to PQF translation does not preserve double-quote
72 Fixed bug #689: SRU diagnostics to be added.
74 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
75 whether a connection is idle (no more work do do).
79 Change type of optval from long to int for invocation of setsockopt with
80 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
82 Added support for specifying the max log file size for the Generic
83 Frontend Server. The size is given with option -r.
87 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
91 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
94 Fixed bug in Generic Frontend Server that could cause a server to stop
95 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
97 For the generic frontend server, the maximum record size is used as maximum
98 size of incoming packages (SRU + Z39.50). The value until was previously
99 only used in Z39.50 Init negotiation and, later, in a session controlled
100 sizes of records returned. This is controlled using -k option. It can be
101 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
103 --- 2.1.28 2006/09/04
105 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
108 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
110 New option for yaz-marcdump -lpos=value which allows setting a portion
111 of MARC header to a certain value.
113 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
115 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
116 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
118 --- 2.1.26 2006/08/15
120 Fixed problem with SRU mode type (soap, get, post) for yaz-client
123 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
125 --- 2.1.24 2006/08/08
127 Fixed MARC ISO2709 encoding routines to deal with character set
130 Minor changes to GFS logging. Database included in search request log
133 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
134 cached/multiple records.
136 Shared libraries are built by default on Unix+configure.
138 Changed cql2pqf transformation to use a different evaluation order. The
139 new order is: always, relation, structure, position, truncation, index
140 and relationModifier. Old order was: always, relation, relationModifier,
141 structure, index, position, truncation. Note that the the latter ones
142 override former ones for identical attributes.. The new scheme means that
143 it is possible to override any existing attribute with a relationModifier.
144 And also that it is possible to override everything for the index rule
145 (except the ones listed in relationModifier). No order is perfect but this
146 one, we believe, covers more real cases.. The "always" should have been
147 called "default", since the attributes there can be overridden with all
150 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
151 compilation phase, but also for yaz-config --cflags output. This allows
152 us to have public headers with Libxml2 stuff in them . It should also,
153 eventually, make Libxml2 checks redundant in packages using YAZ, such
156 --- 2.1.22 2006/06/15
158 Changed SRU update structure bend_update_rr so that SRU diagnostics are
159 stored in uri, message and details.. Previously diagnostics were stored
160 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
161 compatibility.. but he's probably the only one affected, so.
163 Added support for CCL, compiled on the client side, in ZOOM-C. This
164 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
165 input; the resulting query objects can be used for for searching with
166 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
168 YAZ' configure searches for OpenSSL by default.
170 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
171 SL_CTX_use_certificate_file. See
172 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
173 for more info. Thanks to Ko van der Sloot.
175 --- 2.1.20 2006/06/02
177 Bug #600: SRU GET, POST support for yaz-client. Introduced
178 command 'sru' which selects method SOAP/GET/POST.
180 Allow missingValueAction to be specified for the sortspec string -
181 function yaz_sort_spec. By default, the missing value action is null.
182 Use ! to specify "abort". Use = followed by stringvalue to specify default
185 Ensured that Present-handler (if defined) is called in GFS before any call to
186 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
187 searchRetrieve requests.
189 Documentation for YAZ is now based on the Docbook XML/XSLT using
190 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
191 is no longer depending on jade/openjade or docbook-to-man scripts.
192 PDF is no longer part of the distribution - but can optionally be
193 made using DSSSL/jadetex or FOP.
195 Added retrieval handling support in Generic Frontend Server to support
196 conversion between MARC/XML as well as XSLTtransforms. See
197 etc/yazgfs.xml for an example.
199 Added Authentication support to Generic Frontend Server in SRU
200 mode. Authentication using HTTP Basic is supported, as is the use
201 of 'x-username' and 'x-password' parameters in the request itself.
203 Added support for a new character set MARC8s identical to MARC8 except
204 that it converts combined characters to single Unicode characters in the
205 Latin-1 range (when possible).
207 --- 2.1.18 2006/04/24
209 ASN.1 compiler 0.4: generates brief Doxygen file header for
210 generated .h/.c files.
212 Utility yaz_iconv now supports conversion to MARC-8.
214 New facilities for the MARC module. The reading - and writing of
215 content are separate methods for the yaz_marc_t handle. The following
216 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
217 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
218 format). Write functions have prefix yaz_marc_write_.. The existing
219 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
220 available. Removed support for OAI-MARC and simplexml (not the
221 simplexml from PHP5).
223 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
224 to be returned for this connection.
226 --- 2.1.16 2006/03/31
228 Allow multiple languages and charsets to be specified with
229 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
230 negcharset iso-8859-1,utf-8
232 Translation of proximity nodes from CQL into PQF now works.
234 Moved to automake 1.8, 1.9.
236 Added function yaz_log_set_handler which allows a log handler to be
237 installed. This handler will be called for all log messages. Output
238 to file is also produced; but that can be disabled by passing NULL
239 fname to yaz_log_init_file.
241 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
243 For SRW (including GFS), accept application/soap+xml as content-type
246 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
247 produces NO stylesheet reference even if a default stylesheet is specified
250 --- 2.1.14 2006/03/14
252 Updated Windows package to include yazd.dll + yazd.lib for the
253 Development component.
255 If the environment variable YAZ_LOG is set, then it is used as a
256 string indicating the default level of logging to use if not
257 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
258 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
259 used as before. So, for example, to omit warnings from YAZ logging,
262 cql_transform() now map structure and other attributes before indexes,
263 so that index-specific structures and other attributes can override
264 defaults. So now a combination of mapping specifications such as:
266 index.dc.date = 1=date-modified 4=5
267 does the right thing.
269 cql_transform() now also respects the "always" mapping specification,
270 which establishes an initial set of attributes to be used for all
271 terms except where overridden by more specific attributes associated
272 with the index, relation or modifier.
274 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
275 which mode to use; one of "post", "get" or "soap" (SRW, default).
277 Fixes for yaz_iconv routines: changed trie-based character set conversions
278 to use only non-negative values for bit fields due to Sun's C compiler not
279 supporting negative values.
281 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
282 sequences where not read correctly. Fix by Rustam Usmanov.
284 Updated win/makefile to use options, settings which makes things
285 compile with VS C 2005.
287 --- 2.1.12 2006/02/01
289 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
291 In ZOOM socket code, use select instead of poll on MacOSX.
293 ZOOM-C now support client-side compilation of CQL into RPN that is
294 sent to the server, enabling CQL to be used against all Z39.50
295 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
296 ZOOM_query object, and submit it using ZOOM_connection_search().
297 The CQL-to-RPN translation uses a configuration file, the name of
298 which must be specified in the Connection's "cqlfile" option.
300 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
301 function, which takes as its start-term parameter a ZOOM_query object
302 (which may have had either CQL or RPN set into it).
305 --- 2.1.10 2005/11/29
307 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
308 GFS to support this as well. Backend handler, bend_srw_update, does the
309 update work. Code contributed by Ko van der Sloot.
311 Allow retrieval of Search Result-1 information in ZOOM by the use of
312 options that are attached to a result set. ZOOM documentation updated
315 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
316 UTF-8 conversion. Patch by Raj Patel.
318 Added option -m to GFS to control formatting of timestamps in log file.
320 Added 'exit' as synonym for 'quit' in yaz-client
322 Added support for specifying SRW resultSetId + resultSetIdleTime in a
323 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
324 for the new members. Patch by Ko van der Sloot.
326 Added support for SRU POST. It is supported for content-type
327 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
329 Do not build the separate Multi-threaded (MT) library libyazthread.la.
330 Instead make the library libyaz.la multi-threaded. Threading as a whole
331 can still be disabled by configure option --disable-threads. Previosly,
332 with older GLIBCs there were problems with MT libs under Apache. This
333 has now been fixed a long time ago.
335 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
338 CQL module modified to be case insensitive for relations/indexes/operations.
340 Fixed bug in CQL transform code: incorrect value relationModifieder
343 Added 'show all' command for yaz-client which retrieves all results
346 Added new yaz-client, xmles, which takes a (private) OID and
347 a document to be sent as an extended service request.
349 Describe new yaz-client commands wait_response and set_auto_wait.
351 Increase TCP/IP listener backlog from 3 (which I am guessing was
352 copied from the SunOS manual entry way back when) so SOMAXCONN, so
353 that the socket will queue as many incoming connections as it's able
354 to handle ongoing connections. In other words, it will never now
355 refuse a connection that it would be able to handle merely because
356 it's not got around to accepting() enough of the pending connections
357 yet. This is the behaviour anyway under Linux, where the listen()
358 argument is ignored; but not under BSD and on systems such as
359 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
360 YAZ-based servers should now be uniform across operating systems in
363 yaz-marcdump uses 64-bit file access on some systems. This is enabled
364 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
365 This allows yaz-marcdump to read large MARC batches (>2 GB).
367 Modified all YAZ source files - except the source which is auto-generated
368 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
371 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
372 corresponding to the existing *_setl() function. These allow option
373 values containing arbitrary valuues.
375 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
376 ZOOM_resultset_sort() in new applications. Its behaviour is identical
377 except that it returns an indicator of whether or not the sort
378 criterion was accepted (0 for OK, -1 for invalid).
382 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
383 MARC output rather than returning "new" buffer.
385 yaz-client warns about unknown init options.
387 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
391 Added support for SRW sort in Generic Frontend Server. Patch
392 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
393 sortKeys - or NULL if none is provided.
395 Fixed bug #307: It was impossible to specify indefinite/no timeout
396 for ZOOM_event. Special timeout value -1 now means indefinite timeout
399 Added support for multiple languages and charsets to be specified in
400 ZOOM. Each charset/language is separated by a blank. If negotiation is
401 in effect in init-response, Option
402 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
403 Code based on patch by Vasiliy Osadchuk.
405 Fixed bug #306: infinite recursion that occurred when calling
406 yaz_log_level_init as the first call (before other log level or
409 Fixed bug in scan handling in front end server: if preferred-Position-In-
410 Response was non-present, a NULL pointer referece was performed.
414 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
415 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
416 now defined for all those error codes. So instead of putting 109 in
417 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
418 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
420 Modified the yaz-marcdump utility to skip garbage bytes between MARC
423 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
425 Program yaz-client now exits and produces an error message if multiple
426 Z39.50 servers are specified on the command line (none or one allowed
429 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
434 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
436 Fixed bug #272: Preserve spacing for CCL terms.
440 Added support for virtual hosts and multiple backend servers for
441 the YAZ frontend server. The configution is XML based and
442 support specificition of CQL to RPN mappings and explain information.
443 See section "Virtual Hosts" in the YAZ manual.
445 Extended OPAC display utility. OPAC display utility renders
446 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
447 to supplement yaz_marc_decode_wrbuf.
449 Fixed a bug in MARC decoder that could caused it to crash for some
450 invalid MARC records. More diagnostics and warnings where added in
451 XML output (warnings, etc are stored in comments).
453 --- 2.0.34 2005/02/08
455 Fixes for UNIX domain sockets. Bug #261.
457 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
459 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
460 Added yaz_marc_subfield_str which defines subfield lead string which is
461 used in YAZ_MARC_LINE format. Default string is blank+$. Added
462 yaz_marc_endline_str which defines end of fields string used in
463 YAZ_MARC_LINE format. Default string is newline.
465 Experimental support for MarcXChange. This format can be produced
466 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
467 http://www.bs.dk/standards/MarcXchange.xsd
469 Added yaz-client commands scansize that sets maximum number of
470 entries to be returned by scan.
472 --- 2.0.32 2005/01/11
474 Added support for SRW scan in yaz-client and Generic Frontend Server.
476 * Added whereInList member to SRW Scan Term.
478 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
480 Fixed NMEM system to return aligned blocks on the smallest boundaries
481 that are suitably aligned for all possible types on the particular
482 architecture YAZ is being built for.
484 --- 2.0.30 2005/01/04
486 Fixed numerious warnings that was issued with newer versions of GCC.
488 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
489 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
492 Make YAZ Generic Frontend Server slightly faster.
494 Enhance (and reduce) logging for Generic Frontend Server.
496 Revert YAZ log system so that it flushes every write operation
497 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
499 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
500 instead of LOG_, due to name clash with syslog(3). LOG_ are still
501 present. New applications should define YAZ_USE_NEW_LOG=1 - this
502 will effectively disable old definitions.
504 --- 2.0.28 2004/11/09
506 Added yaz_log_time_format which specifies log format using
509 Added yaz_log_module_level which returns mask for a module. Value
510 is non-zero mask a if module is enabled; zero if disabled.
512 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
513 in include/yaz/cql.h.
515 Fixed bug #176: Dont throw diagnostics on empty SRU args.
517 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
519 Fixed bug #172: RPM builds does not enable SSL.
521 Doxyfile.in part of dist. Doxyfile generated by configure.
523 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
524 are given and the corresponding component does not exist.
526 Extend CCL documentation in YAZ reference. Describe r=r.
528 --- 2.0.26 2004/10/01
530 Fixed MARC->MARCXML conversion to properly deal with
531 fields, subfields, indicators having non-ASCII characters.
533 Fixed MARC->MARCXML conversion so that ASCII control characters
534 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
537 Added YAZ GFS support for conversion from Z39.50 surrogate
538 diagnostics to SRW surrogate diagnostics.
540 Bug fix: YAZ GFS did not return schema in explainResponse.
542 --- 2.0.25 2004/09/30
544 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
545 now converts recordSchema to elementSetName as well as schema URI.
547 Fixed bug in COMSTACK that prevented HTTP request packages from being
550 --- 2.0.24 2004/09/29
552 Added CCL facility r=r "range" which is similar to r=o "ordered" but
553 does not require white-space before and after the dash in a range, e.g.
554 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
557 Fixed a few AC_TRY_LINK configure tests that did not operate properly
558 due to new GCC removing "redundant" code.
560 Added yaz-client commands scanpos and scanstep that sets preferred
561 position and step-size for scan.
563 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
565 Added CCL utility ccl_qual_buf which parses one or more CCL
566 spec lines in a buffer.
568 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
569 of name and value - ignoring empty lines and comments.
571 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
573 Added odr_get_element_path which returns current element path for an
574 ODR handle. This utility is useful in error handling or user-defined
577 Added ODR_PRINT utility odr_set_stream which is is a more generic
578 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
579 to a write function and pointer to close function. The close function - if
580 non-NULL - will be called during odr_destroy.
582 Fixed bug in CCL parser where truncation char was not removed from
583 right side when truncation=both was in effect.
585 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
588 --- 2.0.23 2004/08/11
590 Fix buffer overrun in CQL parser when dealing with proximity (%).
592 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
593 to UTF-8/UCS conversion is now only based on codetables.xml.
595 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
597 --- 2.0.22 2004/08/06
599 Add support for more "commit changes" in ZOOM (uses Extended Services).
601 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
604 Yet another small fix for configure of SSL.
606 --- 2.0.21 2004/05/14
608 Fix SSL libs for configure when --with-openssl=DIR is given.
610 --- 2.0.20 2004/05/10
612 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
614 SSL comstack now uses yaz.pem certificate file on server side
615 by default. Certificate filename can be configured by calling
616 comstack function cs_set_ssl_certificate_file before cs_bind is used.
618 Fix bug regarding multiple calls to ZOOM_connection_connect.
620 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
622 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
623 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
625 ZOOM now allows inspection of X509 peer certificate for verification.
626 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
628 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
629 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
630 as "modular" but it simplifies things.
632 Added cs_get_peer_certificate to that returns peer X509 PEM.
634 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
635 NULL if SSL is unavailable.
637 Documentation about MARC decoding tools.

675 Another fix for decoding of XML packed records.
677 --- 2.0.14 2004/02/25
679 Fixes for Chunked encoding. White space not ignored after length spec.
681 Update NS and use default NS for SRW diagnostic elements.
683 --- 2.0.13 2004/02/23
685 Implement ZOOM_resultset_cache_reset which resets record cache.
687 Implement ZOOM_resultset_sort which sorts a result set.
689 Implement chunked HTTP transfer.
691 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
693 --- 2.0.12 2004/02/16
695 Added member 'schema' to bend_explain_rr structure so that backend
696 can specify explain record identifier. Defaults to Zeerex 2.0.
698 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
700 --- 2.0.11 2004/02/16
702 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
705 Added init command for yaz-client which sends "extra" init request.
707 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
708 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
710 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
712 Make ZOOM error code for "invalid query".
714 Fixed compilation for SSL which wasn't properly enabled for all platforms.
716 --- 2.0.10 2004/02/05
718 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
721 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
723 Added option -p <file> to make Generic Frontend Server to write PID file.
725 Added option -D to put Generic Frontend Server in background on its own.
727 Make ZOOM C recognize option "password". If unset, "pass" is used
728 (for backwards compatibility).
730 Fixed a bug in Generic Frontend Server that could make it crash if a
731 client sets characterSetNegotation bit, but didn't pass negotiation stuff
734 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
735 Must be issued before open, in order to be in effect.
737 --- 2.0.9-6 2004/01/12 Debian/Windows
739 Make the SRU server more picky WRT unknown params, etc.
741 Bug fix: ZOOM scan response didn't return displayTerm - when present.
743 New YAZ client command, options, that sets Z39.50 options.
745 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
746 options from a string of tokens (one token for each option bit).
748 Update SRW diagnostic code messages.
750 --- 2.0.9-5 2004/01/07 Debian/Windows
752 Handle user defined stylesheet for SRW/SRU.
754 --- 2.0.9-4 2004/01/06 Debian/Windows
756 Fix bug in decoding of Content-Length.
758 --- 2.0.9-3 2004/01/06 Debian/Windows
760 Fix a bug with decoding of XML packed records.
762 --- 2.0.9-2 2004/01/05 Debian only
764 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
766 Fix bug in SRW/SRU diagnostics decoding.
770 Fixed bug in Generic Frontend Server which could drop records exceeding
771 preferred message size. Reported and fixed by Irina Dijour.
773 Fixed calculation of package size for structured records in Generic
774 Frontend Server. Reported and fixed by Irina Dijour.
776 Fixed namespace for SRW/SRU diagnostics.
778 Fixed SEGV in yaz-client that occured for HTTP connection errors.
782 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
783 this version is incompatible with version 1.0 and older YAZ SRW/SRU
786 CQL changes to reflect recent changes to the specification:
787 * Documentation talks about context sets instead of index sets.
788 * Documentation talks about indexes instead of qualifiers.
789 * The CQL-to-PQF transformer's configuration file now uses
790 "index.set.name = <attributes>" instead of the old form
791 "qualifier.set.name = <attributes>". (Both forms are still
792 understood but the latter is deprecated.)
793 * CQL terms with no explicit index specified are now interpreted as
794 cql.serverChoice instead of srw.serverChoice (which of course
795 behaves exactly the same.)
799 MARC conversion can now generate ISO2709 output in another
800 character set. yaz-marcdump uses this facility if you invoke it
803 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
804 functions from there can be used from C++.
808 Frontend server now transfers memory from decoded packages to stream
811 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
812 references to show up.
814 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
815 the ZOOM Abstract API. The older names for the same options are still
816 also supported for the benefit of old applications.
818 ZOOM-C supports "implementationId" and "implementationVersion" options
819 to go along with "implementationName". These allow the user code to
820 specify identification strings to be sent to servers.
821 Add OID for the new ExtLite attribute set.
823 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
824 as requested/supplid by Ere Maijala <ere@atp.fi>
826 For generic frontend server, reverse the order of
827 "toolkit-supplied / application-supplied" strings sent as implementationId,
828 Name and Version. Also, remove the spaces around the slash. This brings
829 the GFS in line with the behaviour of ZOOM-C on the client side.
831 Add function ZOOM_scanset_display_term.
833 yaz-client shows scan displayTerm if present.
835 Utility yaz-iconv is now installed by default along with the man page
838 Extend configure check for OpenSSL to use pkg-config where available (such
841 Incorporate patch by Morten Bogeskov which allows a Unix file socket
842 server to specify uid/gid/mask for socket using the format
843 unix:[user=uid,][group=gid,][umask=mask,]file=path
844 If file= is omitted the existing format is assumed, e.g.
846 in which case the mask is 0666 (rw for everybody).
848 Major restructure of YAZ source. All source in libyaz is in src directory.
849 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
850 util (utility programs such as ASN.1 compiler, yaz-marcdump).
852 Added man page for utility yaz-marcdump (used to be called marcdump).
853 yaz-marcdump is installed by 'make install'.
855 Fixed a memory leak in Generic Frontend Server that occurred when decoding
856 of incoming package failed.
858 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
860 Change prototype of odr_perror: add const to message string.
862 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
864 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
865 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
866 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
867 DNS lookup. There should not be any compatibility problems with this
868 assuming that blocking=1 or 0 is used.
870 Fix bad reference in UNIX comstack in function cs_addrstr.
872 Fix for compilation on AIX.
874 The generic front-end server (server/seshigh.c) now supports returning
875 Init diagnostics to the client in User-information-field, in
876 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
881 Allow any CQL relation (not just all,any,exact,scr).
883 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
884 that features the same UI.
886 Implemented command update0 in YAZ client which is equivalent to
887 update but uses old of Ext Update ASN.1.
889 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
890 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
891 Previously no OID was used for this info.
893 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
894 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
895 returns 'malformed search term' otherwise.
897 SortResponse member resultCount now set to NULL in sort handler of
900 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
903 Add three new utility functions for translating OIDs between various
904 formats -- symbolic name such as "Usmarc", minus-1-terminated int
905 arrays and dotted strings such as "1.2.840.10003.9.5.1":
906 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
907 char *oid_to_dotstring(const int *oid, char *oidbuf);
908 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
910 Reverted modifications for ES Update definition for z_IU0Update
911 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
912 is back to YAZ 2.0.2.
914 String value attributes for CCL parser.
916 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
917 which their FirstSearch server returns in Init responses, sometimes
918 carrying useful diagnostic information when Init fails. This has the
919 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
920 "z39.50/oclcui.asn", where its definition is somewhat different from
921 what OCLC document on their web-site, as required to interoperate with
924 Support for anonymous authentication in yaz-client. Use the command
927 * Fix the OID of the Index Data-local "admin" Extended Service from
928 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
929 the 1000, which indicates a locally-defined OID, was a mistake.
933 Fix CCL directive @case handling so that it affects string match for
934 both CCL keywords and qualifiers.
936 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
937 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
938 Decoder has been updated with ASN.1 changes as listed in
939 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
940 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
941 z_IUUpdate, remains unchanged.
943 ZOOM_record_get may now return a record in a specific character set.
944 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
945 "from" is the character set of record as returned by target. "to" is
946 the character set to be returned. If omitted, "to" is UTF-8.
948 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
950 New ODR utility, odr_getelement, which returns name of element for
951 which encoding/decoding failed.
953 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
954 in cases where a required element was omitted.
956 Bug fix: some MARC8 sequences were not converted.
958 New ZOOM option "step" which specifies number of records to be
959 retrieved in one chunk. Used in conjunction with "start" and "count".
961 SRW support for yaz-client. Use scheme http: to use it, e.g.
964 yaz-client no longer does (un)intelligent character set conversions
965 by default. Can be enabled with charset and marc_charset commands.
967 xmalloc trace fix for 64-bit systems such as DEC alpha.
969 Solaris 2.6 compile fix.
971 New function, cql_strerror() translates SRW error codes, as returned
972 by cql_transform_error(), into human-readable English strings. Used
973 in yaz-client diagnostics when appropriate.
975 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
976 converts it into a type-1 query which is sent to the server. This
977 makes CQL available for use with all Z-servers, as opposed to the tiny
978 minority that can handle CQL queries themselves.
982 New Debian package layout similar to the Redhat Package layout.
984 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
985 and search result respectively.
989 Redhat package is now several packages: libyaz (runtime libraries),
990 libyaz-devel (development and documentation, and yaz (utility programs).
991 Package spec file by Morten Bøgeskov.
993 New member 'schema' in struct bend_fetch_rr which the name of requested
994 schema (SRW/SRU) for record (or NULL if none was given). The fetch
995 handler MAY set this to reflect the schema of the returned record.
997 New member 'display_term' in struct scan_entry. GFS now sets member entries
998 and allocates scan entries to be filled by user scan handler. In previous
999 version, entries member was allocated by the scan handler. That still works,
1000 but the GFS will ignore member display_term - assuming it was NOT set by
1001 the handler. The fact that the GFS now allocates the entries both allows
1002 for new members and makes a scan handler easier to write.
1004 Fix CQL lex buffer overflow.
1006 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1007 SRU default recordPacking is string.
1009 SRU protocol support for frontend server.
1011 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1013 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1015 Added scan for the ZOOM shell (zoomsh).
1019 * String Identifers for Schemas (Amendment 5).
1020 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1021 Old definition for schema
1022 Odr_oid *schema; /* OPT */
1027 Z_InternationalString *uri;
1028 #define Z_Schema_oid 1
1029 #define Z_Schema_uri 2
1032 * resultCount parameter to Sort Response (Amendment 1).
1033 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1035 Support for SRW 1.0 over HTTP. This is an optional feature and
1036 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1039 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1040 on the same port. SRW SearchRetrieveRequests are mapped
1041 to bend_init,bend_search,bend_fetch,bend_close.
1043 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1045 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1046 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1048 ZOOM connections are SRW based if schem http is used for hostname
1049 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1050 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1052 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1053 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1054 distance=n, order=true/false, relation=le, prox unit=word. If
1055 n is omitted, distance 1 is used.
1057 Fixed problem with C compiler include path in wrong order.
1059 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1060 on Solaris. Patch from Ko van der Sloot.
1062 New MARC decode API. All new functions operate on a yaz_marc_t
1063 handle. The most important new functions are: yaz_marc_create,
1064 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1065 decode and destroy respectively. Decoder can produce formats
1066 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1067 include/yaz/marcdisp.h.
1069 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1070 to UTF-8, UCS-32, wchar_t or Latin-1.
1072 * Prototypes for yaz_iconv_-functions moved to separate header
1073 include/yaz/yaz-iconv.h.
1075 Make a few private functions 'static' in unix.c. This prevents
1076 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1078 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1079 are set when Init Response is received.
1081 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1082 but returns diagnostic set as well.
1084 New function yaz_strerror which is a portable wrapper for
1085 strerror/strerror_r/GetLastMessage.
1087 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1088 is returned for MARC. If type is "oai", then OAI MARC is returned.
1090 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1093 --- 1.9.2 2002/11/26
1095 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1097 Fix bad race conditions on SIGTERM and terminate gracefully in
1100 Move retrieval (data1) module to Zebra since nobody seems to be
1103 Add GRS-1 render for ZOOM using same format as yaz-client.
1105 --- 1.9.1 2002/10/05
1107 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1109 Fix broken ESpec handling in data1 module.
1111 SGML reader parses comments and makes them part of the data1 tree.
1113 Added several type casts so that YAZ compiles as C++ code.
1115 ZOOM didn't handle PDU encoding failures properly.
1117 Added more Bib-1 diagnostics (approved extensions).
1119 GNU configure: better check for iconv.
1121 More portable use of accept, getpeername. Check for socklen_t. Use
1122 int/size_t if socklen_t is not defined.
1126 PQF parser rejects bad queries - including those with extra
1127 characters in them. PQF parser used to silently ignore that.
1128 Cleaner API for PQF added, which allows you to get detailed
1129 error information for bad queries (see yaz/pquery.h).
1131 Fixed bug in ZOOM_record_get for type "database".
1133 Implemented mini iconv library supporting conversions between
1134 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1136 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1138 --- 1.8.9 2002/08/20
1140 Fixed ZOOM C record cache so that preferredRecordSyntax and
1141 elementSetName is used to check for already fetched records.
1143 --- 1.8.8 2002/08/02
1145 Added three members in bend_initrequest structure to facilitate
1146 character set negotiation.
1148 Fixed a bug in frontend server that could cause indefinite
1149 loops under rare conditions.
1151 Revised character set utilities (charneg.h) so that encoding
1152 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1154 For PQF, directive @term <type> sets term type for Scan/Search.
1155 Here <type> is general, string, numeric, null. The term type
1156 is inherited - just like @attr.
1158 New call odr_set_charset that sets character set conversion for
1159 international-strings on a ODR stream. Prototype is:
1160 int odr_set_charset(ODR o, const char *to, const char *from);
1161 The InternationalString is still represented as C string in YAZ
1162 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1163 won't). On the protocol level, you can use any encoding.
1165 Support for UNIX sockets in ZOOM.
1167 Solaris recv sometimes returns errno == ENOENT. It is treated as
1168 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1170 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1171 both client and server. Code by Morten Bøgeskov.
1173 --- 1.8.7 2002/05/22
1175 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1176 that they can be used directly from Visual Basic. You must recompile
1177 your windows APP if you're using ZOOM.
1179 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1180 Commands "lang" and "charset" sets language and character set respectively.
1181 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1182 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1184 Attributes from multiple CCL fields may be OR'ed rather than merged
1185 using directive "@field or". Fields are still merged by default -
1186 equivalent to "@field merge".
1188 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1191 Fixed bug in zget for parameter ExtendedServicesResponse.
1195 --- 1.8.6 2002/03/25
1197 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1199 Client displays USR.1:SearchResult-1 (hits per term).
1201 Additional Search Info for search in Generic Frontend Server.
1203 Fixed CCL parsing of "field=s".
1205 WIN32 installer - using the excellent NSIS software from nullsoft.
1207 Fixed CCL parsing of "field = - <number>".
1209 Added function yaz_marc_decode that decodes MARC for line mode
1210 display or XML (similar to that used by JZKit).
1212 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1213 Z39.50. But ISO/ILL was, however.
1215 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1216 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1218 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1219 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1221 --- 1.8.5 2002/02/03
1223 New YAZ client features: Command completion and new commands:
1224 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1225 Code provided by Jacob Poulsen.
1227 New call oid_trav, that visits all registered OIDs via callback.
1229 Function ZOOM_record_get now returns const char pointer rather than
1230 void pointer. It saves a lot of type casts.
1232 For YAZ client, command "auth" now allows you to set authentication
1233 in IdPass style. It is enabled when three tokens are given - order
1234 is user, group and password.
1236 Fix memory leaks in MARC record handling for ZOOM.
1238 New option for YAZ client, -k <kilobytes> that sets
1239 maximum record size. Similar to -k option for generic frontend
1240 server and yaz-ztest.
1242 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1244 Prefix query parser reports "fail" when bad attribute set is given.
1246 Fix in MARC decoder. Proximity logging. Fix for attribute set
1247 in scan handler for server. Patches by Shigeru Ishida.
1249 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1252 Configure option --with-openssl=<dir> now works when a directory is
1253 specified. Patch provided by Morten Bøgeskov.
1255 New option for YAZ client, -u <auth>, that sets authentication.
1257 ZOOM fix: error information was sometimes "missing", since error
1258 was cleared/reset too when it shouldn't.
1260 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1262 --- 1.8.4 2002/01/04
1264 Scan for ZOOM API. New object ZOOM_scanset. New functions
1265 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1266 ZOOM_scanset_destroy.
1268 New ZOOM function, ZOOM_connection_last_event, that returns type
1269 of last event (such as "receive data", "send data", "apdu received",
1272 New ZOOM option, schema, that specifies schema for retrieval.
1274 New CCL feature. Qualifiers can be aliases for one or more
1275 other qualifiers (if more than one is given, OR is used).
1277 ZOOM uses named result sets if target supports it.
1279 Two new YAZ client commands: . (dot, which sources a script of YAZ
1280 client commands), and ! (to execute shell command.). Implemented
1283 Working on Debian packages.
1285 --- 1.8.3 2001/11/19
1287 YAZ client enables named result sets only if target supports it.
1289 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1291 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1292 with key="host" to get same result.
1294 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1295 Function Z3950_resultset_record(s) returns references to records
1296 "owned" by resultset. To become owner use Z3950_record_clone.
1298 Function z_ext_record handles Extended Services. Thanks to
1301 --- 1.8.2 2001/11/12
1303 CCL Parser fix: ignore token comma when dealing with and-lists.
1305 Documentation updates for COMSTACK.
1307 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1308 Changed prototype Z3950_records. For some functions, int parameters
1309 were changed to size_t.
1311 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1314 New MARC decode/display function, marc_display_exl, which properly rejects
1315 non-ISO2709 records. YAZ client uses it.
1317 --- 1.8.1 2001/10/29
1319 Fix bug: local attribute set wasn't set correctly in PQF strings.
1323 * Old Z39.50 codecs no longer supported.
1325 Added ZOOM C binding. See http://zoom.z3950.org/
1327 Renamed states for COMSTACKs to avoid confusion with events.
1329 Implemented cs_look and proper cs_rcvconnect.
1331 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1333 Configure detects POSIX threads on OpenBSD.
1335 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1336 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1338 When error is returned from present handler, non-surrogate diagnostic
1339 is returned in present response (and fetch handler is no longer called).
1341 * Minor adjustments to pquery parser (PQF). Token characters may be
1342 escaped by using backslash (C-style).
1344 PQF parser allows string attribute values to be specified. For @attr,
1345 non-numeric characters after the equal-sign are treated as strings
1346 (e.g. @attr 9=title).
1348 CCL trunction character may be defined (@truncation in file)
1350 * function zget_ExtendedServicesRequest sets waitAction to
1351 waitIfPossible (was wait).
1353 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1356 CCL operator names may be set in field definition files (CCL_bibset).
1357 See ccl/bib1 for an example.
1359 Fixes in ASN.1 compiler for C++ compatibility.
1361 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1362 and "op_or" to avoid conflict with C++.
1364 Fixed problem with GNU readline detection on Redhat 7.0.
1366 Added step-size for Scan backend handler.
1368 Fixed bug that made the frontend server crash when no attribute
1369 set was specified for scan.
1371 Front-end server automatically switches to original working directory
1372 when installed as an NT service. Previously -w had to be specified to
1375 Added extended attributes for retrieval module (data1), so that data1
1376 records carry d1_readXML/SGML attributes. d1_read also supports
1377 null-data rules ( <tag/>)
1379 On UNIX when POSIX threads are available, a separate library libyazthread
1380 is created. Programmers should link with that library and the yaz library
1381 when using threads. The reason for the split was that some applications
1382 on Linux, such as Apache, doesn't work well when using shared objects that
1385 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1386 (or any frontend server) in SSL mode by specifying ssl: followed by
1387 address. Only tested on UNIX.
1389 Added feature for CCL module. Virtual structure s=al or s=ol generates
1390 and-list and or-list respectively instead of phrase search.
1394 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1395 log_mask_str. This was done to avoid name conflicts with other libraries
1396 (such as other PHP extensions).
1398 Added raw OID member for preferred record syntax (request_format_raw)
1399 and returned record syntax (output_format_raw) for backend fetch method.
1401 Config file yaz-config now accepts options so that it returns specific
1402 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1404 Shared library support for UNIX using GNU libtool.
1406 * Modified backend interface. Request/Response struct's replaced by
1407 one read/write C struct. For example bend_fetchrequest and
1408 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1409 Every handler - even search has to be registered in bend_init
1410 handler. This means that the YAZ library no longer refers to
1411 external functions and it makes it possible to make the whole
1412 thing a single DLL/SO.
1414 Added Segment handler for backend server.
1416 Added Zmbol/Zebra administrative functions to YAZ client.
1418 Threaded frontend server on UNIX (when POSIX Threads are available).
1419 Starting the server with option -T enables multi-threading.
1423 Added configure option --enable-comp/disable-comp to control use
1424 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1425 located in sub directory asn.
1427 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1428 in ${exec_prefix}/bin along with the other programs yaz-client and
1431 GNU automake used to maintain makefiles.
1433 Added several OID's.
1435 Changed retrieval module so that we can load records with no abstract
1436 syntax defined. Tagpaths in these records are fully composed of string
1439 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1443 On UNIX, the generated makefile now supports a proper 'make install'.
1444 The prefix can be set via GNU configure to set the install location
1445 (default is /usr/local).
1447 * YAZ programs client and ztest were renamed to yaz-client and
1448 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1449 locations, such as /usr/bin,/usr/local/bin,etc.
1451 * YAZ Header files were moved from include to include/yaz. YAZ Header
1452 files are referred to as include <yaz/log.h> rather than <log.h>.
1453 The YAZ include path (-I ..) is therefore the same as before. Programmers
1454 should update their #include statements or use -Ipath/include/yaz
1455 instead. The main motivation for doing this change is that YAZ header files
1456 can be installed in "standard" locations /usr/include,/usr/local/include
1457 without introducing conflicts, since ALL YAZ header files are stored
1458 in subdirectory yaz (under /usr/include for example).
1460 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1461 rather than project/workspace files. We switched because project files
1462 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1465 Changed name of logging function, logf, to yaz_log, to prevent name
1466 clash with some math-log functions. The YAZ header log.h defines logf
1467 to yaz_log (#define) so there should be no incompatibilities by this
1470 Added bend_start/bend_stop handlers for server. These handler are
1471 called on start/stop of server. For windows they are called whenever
1472 a service is started/stopped.
1474 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1475 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1476 in util/yc.tcl. The auto-generated C code structures are, in a few
1477 cases, incompatible with the old decoders. There are differences in the
1478 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1479 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1480 The preprocessor variable ASN_COMPILED is defined when the compiled
1481 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1482 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1483 wish to use the old encoders/decoders you can specify --disable-yc
1486 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1487 version so that it supports both new - and old version of DB Update
1489 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1490 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1491 change. The name parameter can be set to 0 in which no name is specified
1492 for the construction. The macros odr_implicit and odr_explicit sets name
1493 parameter to zero for the construction involved. New macros
1494 odr_implicit_tag and odr_explicit_tag are similar to the others,
1495 except that a name parameter is added. For programmers' that don't use
1496 ODR they probably only need to change the call to z_APDU and z_External.
1498 Added access control facility by interfacing the TCP wrapper library.
1499 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1500 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1501 name of the daemon and enables the access control as specified in
1502 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1504 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1505 den Dool <H.M.vdnDool@kub.nl>.
1507 Added reference ID parameter to most functions in server API - refer
1508 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1510 Changed name of ccl library to libccl.a (was ccl.a).
1512 Fixed bug in decoder for Explain (Category TargetInfo).
1514 Added support for GNU readline in client. Thanks to Jacob Poulsen
1515 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1517 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1518 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1519 IMPLEMENTATION! This change was made to the development version before
1520 the ZIG decided to retract the amendment. If any users MUST be
1521 compatible with the original Update definition, PLEASE CONTACT US, and
1522 we will include a separate definition corresponding to the old Update
1523 ES. Note that because of the change to the ASN.1 of the
1524 TaskPackageRecordStructure we cannot define a single structure that
1525 will support both versions.
1527 * Added const modifier to buffer parameter for some ODR/BER encoding
1528 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1529 completeWAIS, odr_dumpBER.
1531 Fixed bug in client.c which caused a crash when a scanResponse didn't
1532 contain positionOfTerm.
1534 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1535 * will cause an error in a client if a non-YAZ target sends both a
1536 * list of Scan entries and non-surrogate diagnostics.
1538 Retrieval module enhancements. Tag sets may be typed in the reference
1539 to it. From the .abs-file the "tagset" directive takes a third optional
1540 integer type for the tag set referenced. From a .tag-file the "include"
1541 directive takes a third optional type as well. The old "type" directive
1542 in the tag set itself is still recognized but acts as the default type
1545 Backend interface change. Individual Scan terms returned from bend_scan
1546 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1547 in include/backend.h.
1549 Retrieval module enhancements. Multiple tag sets and attribute sets may
1550 be specified in abstract syntax specs. Revised the error/warning for
1551 logging messages reported by the retrieval module when reading the
1554 Object Identifier system (oid_..) changed. The API is backwards
1555 compatible but the oid-routines now allocates new OID's when needed.
1556 Raw OID's may be specified in oid_getvalbyname.
1558 YAZ now uses GNU configure to generate Makefile(s).
1560 * Minor changes in some of the member names of DeleteResultSetRequest and
1561 DeleteResultSetResponse. See include/proto.h.
1563 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1564 and added member 'languages' in TargetInfo (which was missing).
1566 Changed the way attribute sets are handled in the retrieval
1567 module. These are now cached, just like the abstract syntaxes
1570 Changed YAZ so that it links with compiled ASN.1.
1572 Added Explain-schema definitions and mapping routines. The following
1573 Explain categories have been implemented: AttributeDetails,
1574 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1576 Fixed minor bug in Windows version of Server Library.
1578 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1580 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1582 Added EXTERNAL: UNIverse Resource Report (non-standard).
1584 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1585 ENUMERATED and SET OF.
1587 * Added 'const' to some of the char pointer arguments for the
1588 functions, data1_read_node, data1_getelementbytagname,
1589 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1592 Fixed bug in data1_insert_taggeddata - the last_child member of
1593 parent wasn't initialised.
1595 * Changed data1_read_record and data1_read_node so that the supplied
1596 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1597 doesn't refer to any parts of the "SGML"-buffer.
1599 Fixed bug in server library (Windows version of statserv_remove).
1601 * Changed code so that it compiles as C++. The type definition
1602 of Odr_fun which is a member of Odr_arm was changed. The result is,
1603 that an explicit typecast is needed for the fun pointer when
1604 using Odr_arm - as in:
1605 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1607 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1609 Implemented the new structured date and time definition as approved
1610 by the ZIG. Added schemaId element to the specificTag in Espec-1
1611 (also approved at the last ZIG). Thanks to RVDM.
1613 Added some Object identifiers (RVDM).
1615 Changed the Update Extended Service (RVDM).
1617 Added command "refid" to client which specifies referenceId for
1618 the following requests.
1620 Implemented extended service handling for server. See ztest.c
1621 for an example as well as backend.h. New handlers are registerd
1622 in the Init handler.
1624 * Changed interface for sort in server.
1626 Added new members to statserv_options_block. It allows a server
1627 to read options from another source than just the command line. Thanks
1628 to Charles Woodfield.
1630 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1631 renamed to zboolean. Some C++ compilers complained about the name.
1633 Minor changes to gils.abs. Added index 's' (sort) on title
1634 and date/time-last-modified.
1636 --- 1.4pl2 1998/1/30
1638 Fixed bug in server library regarding inetd mode (-i). This bug
1639 was introduced by release 1.4.
1641 --- 1.4pl1 1998/1/29
1643 Added sort facility in client and backend server interface.
1645 Fixed problem with dependencies in Makefile(s).
1647 Fixed bugs for encoders/decoders of extended services and
1650 Implemented sub-tree feature for schemas. Sub-trees are
1651 referenced in *.abs-files. See explain.abs for an example
1652 of the use of this feature.
1654 Modified bib1.att; local attributes for ANY didn't include
1655 ANY itself (only affects use of the retrieval module).
1657 Fixed bug in plain SGML reader in function data1_read_node:
1658 tags with prefix "var" was incorrectly interpreted as variants.
1660 Added feature "sub-schemas" to enable references to - and definitions
1661 of - group of elements.
1663 * Removed member parent from type data1_element (in data1.h).
1665 Implemented function odr_nullval() that returns the value of
1668 * Removed member num_children from data1_node (in data1.h).
1670 Made NT service interface part of the server library. The
1671 function statserv_main uses the NT service when required and
1672 calls the statserv_start / statserv_close routines.
1674 Routine zget_SearchRequest and zget_PresentRequest fills
1675 resultSetName/Id member with "default" instead of "Default".
1677 Fixed memory leak in server. Request queue member wasn't freed.
1679 Fixed nmem_exit so that memory is freed.
1683 Revised the CCL parser utility to be thread safe.
1685 Added function, oid_ent_to_oid, to replace the function
1686 oid_getoidbyent, which is not thread safe.
1688 * Added nmem_init and nmem_exit to initialize and release
1689 NMEM resources. Function nmem_init should be called once in the
1690 initial thread before NMEM/ODR is used. statserv.c and client.c
1691 have been changed accordingly. The change was necessary to make
1692 NMEM thread safe. The NMEM memory pool is shared amongst threads
1693 in a process. Unix-based applications will still work fine without
1696 Added NT Services interface for the the Z39.50 (statserv) Server.
1697 Refer to the ztest.c source on the usage.
1699 Windows 95/NT port using MSVC5.0. Project files are included in the
1702 * Defined new 'global' handle for the retrieval (data1) system. The
1703 new handled, data1_handle, describes the state of the data1 system.
1704 This handle is passed as first argument to virtually all
1705 data1 related routines. The functions data1_create and data1_destroy
1706 creates and destroys a data1 handle respectively.
1708 Added ODR encode stream member to all backend request structures
1709 init, search, scan etc. This stream should be used to allocate all
1710 memory used for the response when thread safe operation is needed.
1712 Changed the comstack utility, cs_addstr, to be thread safe. The
1713 returned hostname string returned by the function is now part the
1716 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1717 function. The cs_straddr takes a COMSTACK handle as argument, so this
1718 function must be used after cs_create and before bind/connect.
1719 This function is thread safe.
1721 Moved test server to 'ztest' directory - generic server code still
1722 in 'server' directory.
1724 Made prefix query (pquery.c) utility thread safe.
1726 Added new function modifier YAZ_EXPORT to 'export' public DLL
1727 functions when using windows (see include/yconfig.h).
1729 Added definitions to the OID database (util/oid.c) (RVDM).
1731 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1733 Added call to ccl_rpn_delete in client program.
1735 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1736 release of RPN structure.
1738 Added support for C++, headers uses extern "C" for public definitions.
1739 With input from RVDM.
1741 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1742 Thanks to Ronald van der Meer (RVDM).
1744 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1746 Added support for private extensions to the OID database
1747 (oid_setprivateoids()). Thanks to RVDM.
1749 Added optional, physical ANY (key replication)
1751 Fixed null-reference problem in GRS-1 output filter.
1753 Proximity operator added to Prefix Query Format (PQF).
1755 In test client command "base" accepts multiple databases.
1757 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1761 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1763 Smallish bug-fixes in the new encoders/decoders (explain).
1765 Bug fixed in DeleteRequest.
1767 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1769 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1771 Added SOIF syntax (using private OID for now) to retrieval module and client.
1773 Added Update extended service.
1775 Added SearchResult-1 additional info structure.
1777 Added optional CCL (ISO8777) interpreter as separate module. Available
1780 --- 1.2 1996/6/10 (1st anniversary release)
1782 Added Summary record syntax. Lightly tested.
1784 Added OPAC record syntax. Untested.
1786 Added ResourceReport service encoders/decoders. Untested.
1788 Fixed bug in z_Unit - wrong tagging on unitSystem.
1790 Fixed bug in the DiagRecs decoder.
1792 Added options for max PDU size and session timeout to frontend-server.
1794 Added documentation of query-language parsers and other supporting utilities.
1796 [frontend-server] Added Attribute set to the bend_scanrequest API.
1798 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1799 surrogate diagnostics were generated.
1801 [retrieval] Allow multiple local values for attribute.
1803 [retrieval] Allow multiple attributes per element in .abs files. index type.
1805 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1807 --- 1.1pl2 1996/4/10
1809 Minor changes, mostly specific to Zebra's requirements (retrieval)
1813 Repaired bug in frontend server when running multiple listening
1814 endpoints in dynamic mode.
1816 z_External() now won't break if a known, ASN.1 value comes encapsulated
1817 in an octet-string. The value will pass through unmodified in an Odr_oct.
1819 Added a bit of code to the demo client to decode & display
1820 ASN.1-structured records represented in the octet-aligned branch of
1821 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1823 Added z_ext_getentbyref() to the ASN module. Doc updated.
1825 * Completed the SCAN definition in the ASN module. This may break SCAN
1826 code based on older YAZ-versions at compile-time. The fix is easy -
1829 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1830 under the SCAN definition. Remember to initialize this, server-people.
1832 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1833 that this does not extend to ODR and ASN.
1835 Comstack allows insertion of established socket (primarily for
1836 inetd-operation of servers). Doc updated.
1838 Front-end server can now start from the inetd in TCP mode. Doc
1841 --- 1.0pl4 1996/1/24
1845 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1846 the rank and record number.
1848 Adjustments to the frontend server.
1850 Fixed diagnostic BER dumper. It ignored the file argument.
1854 Various changes to retrieval module.
1856 Changed the union discriminators of the protocol files from enums to
1857 ints paired with #defines.
1859 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1862 *Changed operator in the RPN structure to 'roperator', again to avoid a
1865 Fixed problems in Explain decoders/encoders.
1867 --- 1.0pl2 1995/12/6
1869 Memory bug in log module fixed.
1871 --- 1.0pl1 1995/12/5
1873 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1875 Bug in Explain DatabaseInfo module fixed.
1877 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1881 The shift to v1.0 signals that we now consider the *core* functionality
1882 of YAZ reasonably stable (the core being more or less equivalent to
1883 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1884 tested (Explain not at all - though that will happen soonish).
1886 Minor changes to code to support Windows port.
1888 Various minor changes after we're getting to use GRS-1 & co. more.
1890 Added Espec-1 format.
1892 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1893 of the protocol and it cannot be selected when encoding (maps into 'string'
1894 when decoding). Needed to talk to some servers.
1896 Demo client can request simple element set names.
1898 Added Diagnostic Format encoders/decoders.
1900 Added simple Close handling to frontend server (no hooks for resource
1901 reporting yet), and demonstration client.
1903 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1905 --- 1.0b3 1995/08/24
1907 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1908 handled incorrectly when records were requested in the searchResponse. This
1909 will only affect you if you use the frontend-server.
1911 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1912 Test-client will ask for and print GRS1. Ztest will return dummy records
1915 Added Explain encoders/decoders to the service-level API. Untested.
1917 Added Extended Services: Item Order encoders and decoders to the Service-
1918 level API. Untested. We could use a recent copy of the pertinent bits
1919 of the ILL protocol to add those bits.
1921 Added diagnostic format 1 encoders/decoders to the service-level API.
1924 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1925 odr_cons.c, which causes a more correct output.
1927 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1928 was always set to 0 when no records were requested in the searchRequest.
1930 * Added better external-handling. This shouldn't harm old code that
1931 *encodes* externals. It can break code that looks for a
1932 'single-ASN1-type' representation, since those types that are known
1933 are now decoded immediately. Look at the SUTRS sample code in
1934 seshigh.c and client.c. Documentation updated.
1936 Handling of structured records in bend_fetchresponse. Length -1 marks
1937 structured record, type is deduced from format field.
1939 --- 1.0b2 1995/06/27
1940 Fairly quick maintenance release to add SUTRS support.
1942 Fixed handling of SUTRS records in the demonstration client.
1944 * Added format field to the bend_fetchrequest and bend_fetchresponce
1945 structures of the backend API (frontend server). When the record is
1946 returned, the value of the format field is mapped to an OID. The
1947 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1948 of the record. The special value VAL_NONE in the bend_request means
1949 that no specific format was requested by the client. Documentation
1950 updated accordingly. Test server (ztest) will return a fixed dummy
1951 SUTRS record if your client requests SUTRS.
1953 Documentation updated accordingly.
1955 You can now set external libraries and RANLIB support in the top-level
1959 First public release.
