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 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
20 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
21 Client code may now interrogate options such as "init_opt_sort" to
22 find out whether the server claims to support various options.
26 Added utilities yaz_{set,get}_esn to set/get element set name from
29 Removed the build of libyazthread.la. The libyaz.so is the threaded version
30 of YAZ and has been so since YAZ 2.1.10.
32 Implemented ZOOM_record_error which returns error information for
33 record (surrogate diagnostic).
37 Updates for SRU Update by Ko van der Sloot:
38 1. Changed name from "operation" to "action"
39 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
40 versions in the code, marked as 'backward compatible'.
41 3. Added diagnostics for SRU Update.
43 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
45 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
47 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
49 For GFS, fixed problem with SRU diagnostic 'First record position out of
50 range' being issued for 0 hits.
52 zoomtst10 part of Windows Build.
56 Implemented yaz_filepath_comp which splits a path into file path
57 components (required by Zebra 2.0.3+).
59 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
60 BSD inspired license until now so this should not have any real impact on
61 anybody. See http://www.opensource.org/licenses/bsd-license.php
63 Fixed bug #687: Missing log lines.
65 Fixed bug #678: CQL to PQF translation does not preserve double-quote
68 Fixed bug #689: SRU diagnostics to be added.
70 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
71 whether a connection is idle (no more work do do).
75 Change type of optval from long to int for invocation of setsockopt with
76 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
78 Added support for specifying the max log file size for the Generic
79 Frontend Server. The size is given with option -r.
83 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
87 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
90 Fixed bug in Generic Frontend Server that could cause a server to stop
91 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
93 For the generic frontend server, the maximum record size is used as maximum
94 size of incoming packages (SRU + Z39.50). The value until was previously
95 only used in Z39.50 Init negotiation and, later, in a session controlled
96 sizes of records returned. This is controlled using -k option. It can be
97 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
101 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
104 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
106 New option for yaz-marcdump -lpos=value which allows setting a portion
107 of MARC header to a certain value.
109 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
111 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
112 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
114 --- 2.1.26 2006/08/15
116 Fixed problem with SRU mode type (soap, get, post) for yaz-client
119 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
121 --- 2.1.24 2006/08/08
123 Fixed MARC ISO2709 encoding routines to deal with character set
126 Minor changes to GFS logging. Database included in search request log
129 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
130 cached/multiple records.
132 Shared libraries are built by default on Unix+configure.
134 Changed cql2pqf transformation to use a different evaluation order. The
135 new order is: always, relation, structure, position, truncation, index
136 and relationModifier. Old order was: always, relation, relationModifier,
137 structure, index, position, truncation. Note that the the latter ones
138 override former ones for identical attributes.. The new scheme means that
139 it is possible to override any existing attribute with a relationModifier.
140 And also that it is possible to override everything for the index rule
141 (except the ones listed in relationModifier). No order is perfect but this
142 one, we believe, covers more real cases.. The "always" should have been
143 called "default", since the attributes there can be overridden with all
146 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
147 compilation phase, but also for yaz-config --cflags output. This allows
148 us to have public headers with Libxml2 stuff in them . It should also,
149 eventually, make Libxml2 checks redundant in packages using YAZ, such
152 --- 2.1.22 2006/06/15
154 Changed SRU update structure bend_update_rr so that SRU diagnostics are
155 stored in uri, message and details.. Previously diagnostics were stored
156 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
157 compatibility.. but he's probably the only one affected, so.
159 Added support for CCL, compiled on the client side, in ZOOM-C. This
160 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
161 input; the resulting query objects can be used for for searching with
162 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
164 YAZ' configure searches for OpenSSL by default.
166 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
167 SL_CTX_use_certificate_file. See
168 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
169 for more info. Thanks to Ko van der Sloot.
171 --- 2.1.20 2006/06/02
173 Bug #600: SRU GET, POST support for yaz-client. Introduced
174 command 'sru' which selects method SOAP/GET/POST.
176 Allow missingValueAction to be specified for the sortspec string -
177 function yaz_sort_spec. By default, the missing value action is null.
178 Use ! to specify "abort". Use = followed by stringvalue to specify default
181 Ensured that Present-handler (if defined) is called in GFS before any call to
182 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
183 searchRetrieve requests.
185 Documentation for YAZ is now based on the Docbook XML/XSLT using
186 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
187 is no longer depending on jade/openjade or docbook-to-man scripts.
188 PDF is no longer part of the distribution - but can optionally be
189 made using DSSSL/jadetex or FOP.
191 Added retrieval handling support in Generic Frontend Server to support
192 conversion between MARC/XML as well as XSLTtransforms. See
193 etc/yazgfs.xml for an example.
195 Added Authentication support to Generic Frontend Server in SRU
196 mode. Authentication using HTTP Basic is supported, as is the use
197 of 'x-username' and 'x-password' parameters in the request itself.
199 Added support for a new character set MARC8s identical to MARC8 except
200 that it converts combined characters to single Unicode characters in the
201 Latin-1 range (when possible).
203 --- 2.1.18 2006/04/24
205 ASN.1 compiler 0.4: generates brief Doxygen file header for
206 generated .h/.c files.
208 Utility yaz_iconv now supports conversion to MARC-8.
210 New facilities for the MARC module. The reading - and writing of
211 content are separate methods for the yaz_marc_t handle. The following
212 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
213 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
214 format). Write functions have prefix yaz_marc_write_.. The existing
215 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
216 available. Removed support for OAI-MARC and simplexml (not the
217 simplexml from PHP5).
219 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
220 to be returned for this connection.
222 --- 2.1.16 2006/03/31
224 Allow multiple languages and charsets to be specified with
225 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
226 negcharset iso-8859-1,utf-8
228 Translation of proximity nodes from CQL into PQF now works.
230 Moved to automake 1.8, 1.9.
232 Added function yaz_log_set_handler which allows a log handler to be
233 installed. This handler will be called for all log messages. Output
234 to file is also produced; but that can be disabled by passing NULL
235 fname to yaz_log_init_file.
237 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
239 For SRW (including GFS), accept application/soap+xml as content-type
242 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
243 produces NO stylesheet reference even if a default stylesheet is specified
246 --- 2.1.14 2006/03/14
248 Updated Windows package to include yazd.dll + yazd.lib for the
249 Development component.
251 If the environment variable YAZ_LOG is set, then it is used as a
252 string indicating the default level of logging to use if not
253 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
254 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
255 used as before. So, for example, to omit warnings from YAZ logging,
258 cql_transform() now map structure and other attributes before indexes,
259 so that index-specific structures and other attributes can override
260 defaults. So now a combination of mapping specifications such as:
262 index.dc.date = 1=date-modified 4=5
263 does the right thing.
265 cql_transform() now also respects the "always" mapping specification,
266 which establishes an initial set of attributes to be used for all
267 terms except where overridden by more specific attributes associated
268 with the index, relation or modifier.
270 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
271 which mode to use; one of "post", "get" or "soap" (SRW, default).
273 Fixes for yaz_iconv routines: changed trie-based character set conversions
274 to use only non-negative values for bit fields due to Sun's C compiler not
275 supporting negative values.
277 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
278 sequences where not read correctly. Fix by Rustam Usmanov.
280 Updated win/makefile to use options, settings which makes things
281 compile with VS C 2005.
283 --- 2.1.12 2006/02/01
285 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
287 In ZOOM socket code, use select instead of poll on MacOSX.
289 ZOOM-C now support client-side compilation of CQL into RPN that is
290 sent to the server, enabling CQL to be used against all Z39.50
291 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
292 ZOOM_query object, and submit it using ZOOM_connection_search().
293 The CQL-to-RPN translation uses a configuration file, the name of
294 which must be specified in the Connection's "cqlfile" option.
296 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
297 function, which takes as its start-term parameter a ZOOM_query object
298 (which may have had either CQL or RPN set into it).
301 --- 2.1.10 2005/11/29
303 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
304 GFS to support this as well. Backend handler, bend_srw_update, does the
305 update work. Code contributed by Ko van der Sloot.
307 Allow retrieval of Search Result-1 information in ZOOM by the use of
308 options that are attached to a result set. ZOOM documentation updated
311 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
312 UTF-8 conversion. Patch by Raj Patel.
314 Added option -m to GFS to control formatting of timestamps in log file.
316 Added 'exit' as synonym for 'quit' in yaz-client
318 Added support for specifying SRW resultSetId + resultSetIdleTime in a
319 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
320 for the new members. Patch by Ko van der Sloot.
322 Added support for SRU POST. It is supported for content-type
323 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
325 Do not build the separate Multi-threaded (MT) library libyazthread.la.
326 Instead make the library libyaz.la multi-threaded. Threading as a whole
327 can still be disabled by configure option --disable-threads. Previosly,
328 with older GLIBCs there were problems with MT libs under Apache. This
329 has now been fixed a long time ago.
331 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
334 CQL module modified to be case insensitive for relations/indexes/operations.
336 Fixed bug in CQL transform code: incorrect value relationModifieder
339 Added 'show all' command for yaz-client which retrieves all results
342 Added new yaz-client, xmles, which takes a (private) OID and
343 a document to be sent as an extended service request.
345 Describe new yaz-client commands wait_response and set_auto_wait.
347 Increase TCP/IP listener backlog from 3 (which I am guessing was
348 copied from the SunOS manual entry way back when) so SOMAXCONN, so
349 that the socket will queue as many incoming connections as it's able
350 to handle ongoing connections. In other words, it will never now
351 refuse a connection that it would be able to handle merely because
352 it's not got around to accepting() enough of the pending connections
353 yet. This is the behaviour anyway under Linux, where the listen()
354 argument is ignored; but not under BSD and on systems such as
355 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
356 YAZ-based servers should now be uniform across operating systems in
359 yaz-marcdump uses 64-bit file access on some systems. This is enabled
360 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
361 This allows yaz-marcdump to read large MARC batches (>2 GB).
363 Modified all YAZ source files - except the source which is auto-generated
364 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
367 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
368 corresponding to the existing *_setl() function. These allow option
369 values containing arbitrary valuues.
371 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
372 ZOOM_resultset_sort() in new applications. Its behaviour is identical
373 except that it returns an indicator of whether or not the sort
374 criterion was accepted (0 for OK, -1 for invalid).
378 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
379 MARC output rather than returning "new" buffer.
381 yaz-client warns about unknown init options.
383 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
387 Added support for SRW sort in Generic Frontend Server. Patch
388 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
389 sortKeys - or NULL if none is provided.
391 Fixed bug #307: It was impossible to specify indefinite/no timeout
392 for ZOOM_event. Special timeout value -1 now means indefinite timeout
395 Added support for multiple languages and charsets to be specified in
396 ZOOM. Each charset/language is separated by a blank. If negotiation is
397 in effect in init-response, Option
398 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
399 Code based on patch by Vasiliy Osadchuk.
401 Fixed bug #306: infinite recursion that occurred when calling
402 yaz_log_level_init as the first call (before other log level or
405 Fixed bug in scan handling in front end server: if preferred-Position-In-
406 Response was non-present, a NULL pointer referece was performed.
410 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
411 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
412 now defined for all those error codes. So instead of putting 109 in
413 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
414 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
416 Modified the yaz-marcdump utility to skip garbage bytes between MARC
419 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
421 Program yaz-client now exits and produces an error message if multiple
422 Z39.50 servers are specified on the command line (none or one allowed
425 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
430 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
432 Fixed bug #272: Preserve spacing for CCL terms.
436 Added support for virtual hosts and multiple backend servers for
437 the YAZ frontend server. The configution is XML based and
438 support specificition of CQL to RPN mappings and explain information.
439 See section "Virtual Hosts" in the YAZ manual.
441 Extended OPAC display utility. OPAC display utility renders
442 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
443 to supplement yaz_marc_decode_wrbuf.
445 Fixed a bug in MARC decoder that could caused it to crash for some
446 invalid MARC records. More diagnostics and warnings where added in
447 XML output (warnings, etc are stored in comments).
449 --- 2.0.34 2005/02/08
451 Fixes for UNIX domain sockets. Bug #261.
453 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
455 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
456 Added yaz_marc_subfield_str which defines subfield lead string which is
457 used in YAZ_MARC_LINE format. Default string is blank+$. Added
458 yaz_marc_endline_str which defines end of fields string used in
459 YAZ_MARC_LINE format. Default string is newline.
461 Experimental support for MarcXChange. This format can be produced
462 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
463 http://www.bs.dk/standards/MarcXchange.xsd
465 Added yaz-client commands scansize that sets maximum number of
466 entries to be returned by scan.
468 --- 2.0.32 2005/01/11
470 Added support for SRW scan in yaz-client and Generic Frontend Server.
472 * Added whereInList member to SRW Scan Term.
474 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
476 Fixed NMEM system to return aligned blocks on the smallest boundaries
477 that are suitably aligned for all possible types on the particular
478 architecture YAZ is being built for.
480 --- 2.0.30 2005/01/04
482 Fixed numerious warnings that was issued with newer versions of GCC.
484 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
485 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
488 Make YAZ Generic Frontend Server slightly faster.
490 Enhance (and reduce) logging for Generic Frontend Server.
492 Revert YAZ log system so that it flushes every write operation
493 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
495 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
496 instead of LOG_, due to name clash with syslog(3). LOG_ are still
497 present. New applications should define YAZ_USE_NEW_LOG=1 - this
498 will effectively disable old definitions.
500 --- 2.0.28 2004/11/09
502 Added yaz_log_time_format which specifies log format using
505 Added yaz_log_module_level which returns mask for a module. Value
506 is non-zero mask a if module is enabled; zero if disabled.
508 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
509 in include/yaz/cql.h.
511 Fixed bug #176: Dont throw diagnostics on empty SRU args.
513 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
515 Fixed bug #172: RPM builds does not enable SSL.
517 Doxyfile.in part of dist. Doxyfile generated by configure.
519 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
520 are given and the corresponding component does not exist.
522 Extend CCL documentation in YAZ reference. Describe r=r.
524 --- 2.0.26 2004/10/01
526 Fixed MARC->MARCXML conversion to properly deal with
527 fields, subfields, indicators having non-ASCII characters.
529 Fixed MARC->MARCXML conversion so that ASCII control characters
530 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
533 Added YAZ GFS support for conversion from Z39.50 surrogate
534 diagnostics to SRW surrogate diagnostics.
536 Bug fix: YAZ GFS did not return schema in explainResponse.
538 --- 2.0.25 2004/09/30
540 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
541 now converts recordSchema to elementSetName as well as schema URI.
543 Fixed bug in COMSTACK that prevented HTTP request packages from being
546 --- 2.0.24 2004/09/29
548 Added CCL facility r=r "range" which is similar to r=o "ordered" but
549 does not require white-space before and after the dash in a range, e.g.
550 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
553 Fixed a few AC_TRY_LINK configure tests that did not operate properly
554 due to new GCC removing "redundant" code.
556 Added yaz-client commands scanpos and scanstep that sets preferred
557 position and step-size for scan.
559 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
561 Added CCL utility ccl_qual_buf which parses one or more CCL
562 spec lines in a buffer.
564 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
565 of name and value - ignoring empty lines and comments.
567 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
569 Added odr_get_element_path which returns current element path for an
570 ODR handle. This utility is useful in error handling or user-defined
573 Added ODR_PRINT utility odr_set_stream which is is a more generic
574 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
575 to a write function and pointer to close function. The close function - if
576 non-NULL - will be called during odr_destroy.
578 Fixed bug in CCL parser where truncation char was not removed from
579 right side when truncation=both was in effect.
581 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
584 --- 2.0.23 2004/08/11
586 Fix buffer overrun in CQL parser when dealing with proximity (%).
588 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
589 to UTF-8/UCS conversion is now only based on codetables.xml.
591 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
593 --- 2.0.22 2004/08/06
595 Add support for more "commit changes" in ZOOM (uses Extended Services).
597 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
600 Yet another small fix for configure of SSL.
602 --- 2.0.21 2004/05/14
604 Fix SSL libs for configure when --with-openssl=DIR is given.
606 --- 2.0.20 2004/05/10
608 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
610 SSL comstack now uses yaz.pem certificate file on server side
611 by default. Certificate filename can be configured by calling
612 comstack function cs_set_ssl_certificate_file before cs_bind is used.
614 Fix bug regarding multiple calls to ZOOM_connection_connect.
616 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
618 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
619 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
621 ZOOM now allows inspection of X509 peer certificate for verification.
622 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
624 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
625 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
626 as "modular" but it simplifies things.
628 Added cs_get_peer_certificate to that returns peer X509 PEM.
630 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
631 NULL if SSL is unavailable.

683 Implement ZOOM_resultset_sort which sorts a result set.
685 Implement chunked HTTP transfer.
687 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
689 --- 2.0.12 2004/02/16
691 Added member 'schema' to bend_explain_rr structure so that backend
692 can specify explain record identifier. Defaults to Zeerex 2.0.
694 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
696 --- 2.0.11 2004/02/16
698 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
701 Added init command for yaz-client which sends "extra" init request.
703 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
704 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
706 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
708 Make ZOOM error code for "invalid query".
710 Fixed compilation for SSL which wasn't properly enabled for all platforms.
712 --- 2.0.10 2004/02/05
714 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
717 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
719 Added option -p <file> to make Generic Frontend Server to write PID file.
721 Added option -D to put Generic Frontend Server in background on its own.
723 Make ZOOM C recognize option "password". If unset, "pass" is used
724 (for backwards compatibility).
726 Fixed a bug in Generic Frontend Server that could make it crash if a
727 client sets characterSetNegotation bit, but didn't pass negotiation stuff
730 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
731 Must be issued before open, in order to be in effect.
733 --- 2.0.9-6 2004/01/12 Debian/Windows
735 Make the SRU server more picky WRT unknown params, etc.
737 Bug fix: ZOOM scan response didn't return displayTerm - when present.
739 New YAZ client command, options, that sets Z39.50 options.
741 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
742 options from a string of tokens (one token for each option bit).
744 Update SRW diagnostic code messages.
746 --- 2.0.9-5 2004/01/07 Debian/Windows
748 Handle user defined stylesheet for SRW/SRU.
750 --- 2.0.9-4 2004/01/06 Debian/Windows
752 Fix bug in decoding of Content-Length.
754 --- 2.0.9-3 2004/01/06 Debian/Windows
756 Fix a bug with decoding of XML packed records.
758 --- 2.0.9-2 2004/01/05 Debian only
760 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
762 Fix bug in SRW/SRU diagnostics decoding.
766 Fixed bug in Generic Frontend Server which could drop records exceeding
767 preferred message size. Reported and fixed by Irina Dijour.
769 Fixed calculation of package size for structured records in Generic
770 Frontend Server. Reported and fixed by Irina Dijour.
772 Fixed namespace for SRW/SRU diagnostics.
774 Fixed SEGV in yaz-client that occured for HTTP connection errors.
778 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
779 this version is incompatible with version 1.0 and older YAZ SRW/SRU
782 CQL changes to reflect recent changes to the specification:
783 * Documentation talks about context sets instead of index sets.
784 * Documentation talks about indexes instead of qualifiers.
785 * The CQL-to-PQF transformer's configuration file now uses
786 "index.set.name = <attributes>" instead of the old form
787 "qualifier.set.name = <attributes>". (Both forms are still
788 understood but the latter is deprecated.)
789 * CQL terms with no explicit index specified are now interpreted as
790 cql.serverChoice instead of srw.serverChoice (which of course
791 behaves exactly the same.)
795 MARC conversion can now generate ISO2709 output in another
796 character set. yaz-marcdump uses this facility if you invoke it
799 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
800 functions from there can be used from C++.
804 Frontend server now transfers memory from decoded packages to stream
807 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
808 references to show up.
810 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
811 the ZOOM Abstract API. The older names for the same options are still
812 also supported for the benefit of old applications.
814 ZOOM-C supports "implementationId" and "implementationVersion" options
815 to go along with "implementationName". These allow the user code to
816 specify identification strings to be sent to servers.
817 Add OID for the new ExtLite attribute set.
819 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
820 as requested/supplid by Ere Maijala <ere@atp.fi>
822 For generic frontend server, reverse the order of
823 "toolkit-supplied / application-supplied" strings sent as implementationId,
824 Name and Version. Also, remove the spaces around the slash. This brings
825 the GFS in line with the behaviour of ZOOM-C on the client side.
827 Add function ZOOM_scanset_display_term.
829 yaz-client shows scan displayTerm if present.
831 Utility yaz-iconv is now installed by default along with the man page
834 Extend configure check for OpenSSL to use pkg-config where available (such
837 Incorporate patch by Morten Bogeskov which allows a Unix file socket
838 server to specify uid/gid/mask for socket using the format
839 unix:[user=uid,][group=gid,][umask=mask,]file=path
840 If file= is omitted the existing format is assumed, e.g.
842 in which case the mask is 0666 (rw for everybody).
844 Major restructure of YAZ source. All source in libyaz is in src directory.
845 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
846 util (utility programs such as ASN.1 compiler, yaz-marcdump).
848 Added man page for utility yaz-marcdump (used to be called marcdump).
849 yaz-marcdump is installed by 'make install'.
851 Fixed a memory leak in Generic Frontend Server that occurred when decoding
852 of incoming package failed.
854 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
856 Change prototype of odr_perror: add const to message string.
858 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
860 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
861 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
862 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
863 DNS lookup. There should not be any compatibility problems with this
864 assuming that blocking=1 or 0 is used.
866 Fix bad reference in UNIX comstack in function cs_addrstr.
868 Fix for compilation on AIX.
870 The generic front-end server (server/seshigh.c) now supports returning
871 Init diagnostics to the client in User-information-field, in
872 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
877 Allow any CQL relation (not just all,any,exact,scr).
879 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
880 that features the same UI.
882 Implemented command update0 in YAZ client which is equivalent to
883 update but uses old of Ext Update ASN.1.
885 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
886 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
887 Previously no OID was used for this info.
889 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
890 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
891 returns 'malformed search term' otherwise.
893 SortResponse member resultCount now set to NULL in sort handler of
896 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
899 Add three new utility functions for translating OIDs between various
900 formats -- symbolic name such as "Usmarc", minus-1-terminated int
901 arrays and dotted strings such as "1.2.840.10003.9.5.1":
902 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
903 char *oid_to_dotstring(const int *oid, char *oidbuf);
904 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
906 Reverted modifications for ES Update definition for z_IU0Update
907 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
908 is back to YAZ 2.0.2.
910 String value attributes for CCL parser.
912 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
913 which their FirstSearch server returns in Init responses, sometimes
914 carrying useful diagnostic information when Init fails. This has the
915 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
916 "z39.50/oclcui.asn", where its definition is somewhat different from
917 what OCLC document on their web-site, as required to interoperate with
920 Support for anonymous authentication in yaz-client. Use the command
923 * Fix the OID of the Index Data-local "admin" Extended Service from
924 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
925 the 1000, which indicates a locally-defined OID, was a mistake.
929 Fix CCL directive @case handling so that it affects string match for
930 both CCL keywords and qualifiers.
932 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
933 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
934 Decoder has been updated with ASN.1 changes as listed in
935 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
936 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
937 z_IUUpdate, remains unchanged.
939 ZOOM_record_get may now return a record in a specific character set.
940 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
941 "from" is the character set of record as returned by target. "to" is
942 the character set to be returned. If omitted, "to" is UTF-8.
944 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
946 New ODR utility, odr_getelement, which returns name of element for
947 which encoding/decoding failed.
949 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
950 in cases where a required element was omitted.
952 Bug fix: some MARC8 sequences were not converted.
954 New ZOOM option "step" which specifies number of records to be
955 retrieved in one chunk. Used in conjunction with "start" and "count".
957 SRW support for yaz-client. Use scheme http: to use it, e.g.
960 yaz-client no longer does (un)intelligent character set conversions
961 by default. Can be enabled with charset and marc_charset commands.
963 xmalloc trace fix for 64-bit systems such as DEC alpha.
965 Solaris 2.6 compile fix.
967 New function, cql_strerror() translates SRW error codes, as returned
968 by cql_transform_error(), into human-readable English strings. Used
969 in yaz-client diagnostics when appropriate.
971 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
972 converts it into a type-1 query which is sent to the server. This
973 makes CQL available for use with all Z-servers, as opposed to the tiny
974 minority that can handle CQL queries themselves.
978 New Debian package layout similar to the Redhat Package layout.
980 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
981 and search result respectively.
985 Redhat package is now several packages: libyaz (runtime libraries),
986 libyaz-devel (development and documentation, and yaz (utility programs).
987 Package spec file by Morten Bøgeskov.
989 New member 'schema' in struct bend_fetch_rr which the name of requested
990 schema (SRW/SRU) for record (or NULL if none was given). The fetch
991 handler MAY set this to reflect the schema of the returned record.
993 New member 'display_term' in struct scan_entry. GFS now sets member entries
994 and allocates scan entries to be filled by user scan handler. In previous
995 version, entries member was allocated by the scan handler. That still works,
996 but the GFS will ignore member display_term - assuming it was NOT set by
997 the handler. The fact that the GFS now allocates the entries both allows
998 for new members and makes a scan handler easier to write.
1000 Fix CQL lex buffer overflow.
1002 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1003 SRU default recordPacking is string.
1005 SRU protocol support for frontend server.
1007 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1009 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1011 Added scan for the ZOOM shell (zoomsh).
1015 * String Identifers for Schemas (Amendment 5).
1016 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1017 Old definition for schema
1018 Odr_oid *schema; /* OPT */
1023 Z_InternationalString *uri;
1024 #define Z_Schema_oid 1
1025 #define Z_Schema_uri 2
1028 * resultCount parameter to Sort Response (Amendment 1).
1029 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1031 Support for SRW 1.0 over HTTP. This is an optional feature and
1032 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1035 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1036 on the same port. SRW SearchRetrieveRequests are mapped
1037 to bend_init,bend_search,bend_fetch,bend_close.
1039 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1041 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1042 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1044 ZOOM connections are SRW based if schem http is used for hostname
1045 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1046 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1048 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1049 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1050 distance=n, order=true/false, relation=le, prox unit=word. If
1051 n is omitted, distance 1 is used.
1053 Fixed problem with C compiler include path in wrong order.
1055 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1056 on Solaris. Patch from Ko van der Sloot.
1058 New MARC decode API. All new functions operate on a yaz_marc_t
1059 handle. The most important new functions are: yaz_marc_create,
1060 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1061 decode and destroy respectively. Decoder can produce formats
1062 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1063 include/yaz/marcdisp.h.
1065 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1066 to UTF-8, UCS-32, wchar_t or Latin-1.
1068 * Prototypes for yaz_iconv_-functions moved to separate header
1069 include/yaz/yaz-iconv.h.
1071 Make a few private functions 'static' in unix.c. This prevents
1072 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1074 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1075 are set when Init Response is received.
1077 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1078 but returns diagnostic set as well.
1080 New function yaz_strerror which is a portable wrapper for
1081 strerror/strerror_r/GetLastMessage.
1083 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1084 is returned for MARC. If type is "oai", then OAI MARC is returned.
1086 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1089 --- 1.9.2 2002/11/26
1091 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1093 Fix bad race conditions on SIGTERM and terminate gracefully in
1096 Move retrieval (data1) module to Zebra since nobody seems to be
1099 Add GRS-1 render for ZOOM using same format as yaz-client.
1101 --- 1.9.1 2002/10/05
1103 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1105 Fix broken ESpec handling in data1 module.
1107 SGML reader parses comments and makes them part of the data1 tree.
1109 Added several type casts so that YAZ compiles as C++ code.
1111 ZOOM didn't handle PDU encoding failures properly.
1113 Added more Bib-1 diagnostics (approved extensions).
1115 GNU configure: better check for iconv.
1117 More portable use of accept, getpeername. Check for socklen_t. Use
1118 int/size_t if socklen_t is not defined.
1122 PQF parser rejects bad queries - including those with extra
1123 characters in them. PQF parser used to silently ignore that.
1124 Cleaner API for PQF added, which allows you to get detailed
1125 error information for bad queries (see yaz/pquery.h).
1127 Fixed bug in ZOOM_record_get for type "database".
1129 Implemented mini iconv library supporting conversions between
1130 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1132 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1134 --- 1.8.9 2002/08/20
1136 Fixed ZOOM C record cache so that preferredRecordSyntax and
1137 elementSetName is used to check for already fetched records.
1139 --- 1.8.8 2002/08/02
1141 Added three members in bend_initrequest structure to facilitate
1142 character set negotiation.
1144 Fixed a bug in frontend server that could cause indefinite
1145 loops under rare conditions.
1147 Revised character set utilities (charneg.h) so that encoding
1148 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1150 For PQF, directive @term <type> sets term type for Scan/Search.
1151 Here <type> is general, string, numeric, null. The term type
1152 is inherited - just like @attr.
1154 New call odr_set_charset that sets character set conversion for
1155 international-strings on a ODR stream. Prototype is:
1156 int odr_set_charset(ODR o, const char *to, const char *from);
1157 The InternationalString is still represented as C string in YAZ
1158 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1159 won't). On the protocol level, you can use any encoding.
1161 Support for UNIX sockets in ZOOM.
1163 Solaris recv sometimes returns errno == ENOENT. It is treated as
1164 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1166 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1167 both client and server. Code by Morten Bøgeskov.
1169 --- 1.8.7 2002/05/22
1171 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1172 that they can be used directly from Visual Basic. You must recompile
1173 your windows APP if you're using ZOOM.
1175 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1176 Commands "lang" and "charset" sets language and character set respectively.
1177 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1178 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1180 Attributes from multiple CCL fields may be OR'ed rather than merged
1181 using directive "@field or". Fields are still merged by default -
1182 equivalent to "@field merge".
1184 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1187 Fixed bug in zget for parameter ExtendedServicesResponse.
1191 --- 1.8.6 2002/03/25
1193 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1195 Client displays USR.1:SearchResult-1 (hits per term).
1197 Additional Search Info for search in Generic Frontend Server.
1199 Fixed CCL parsing of "field=s".
1201 WIN32 installer - using the excellent NSIS software from nullsoft.
1203 Fixed CCL parsing of "field = - <number>".
1205 Added function yaz_marc_decode that decodes MARC for line mode
1206 display or XML (similar to that used by JZKit).
1208 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1209 Z39.50. But ISO/ILL was, however.
1211 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1212 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1214 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1215 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1217 --- 1.8.5 2002/02/03
1219 New YAZ client features: Command completion and new commands:
1220 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1221 Code provided by Jacob Poulsen.
1223 New call oid_trav, that visits all registered OIDs via callback.
1225 Function ZOOM_record_get now returns const char pointer rather than
1226 void pointer. It saves a lot of type casts.
1228 For YAZ client, command "auth" now allows you to set authentication
1229 in IdPass style. It is enabled when three tokens are given - order
1230 is user, group and password.
1232 Fix memory leaks in MARC record handling for ZOOM.
1234 New option for YAZ client, -k <kilobytes> that sets
1235 maximum record size. Similar to -k option for generic frontend
1236 server and yaz-ztest.
1238 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1240 Prefix query parser reports "fail" when bad attribute set is given.
1242 Fix in MARC decoder. Proximity logging. Fix for attribute set
1243 in scan handler for server. Patches by Shigeru Ishida.
1245 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1248 Configure option --with-openssl=<dir> now works when a directory is
1249 specified. Patch provided by Morten Bøgeskov.
1251 New option for YAZ client, -u <auth>, that sets authentication.
1253 ZOOM fix: error information was sometimes "missing", since error
1254 was cleared/reset too when it shouldn't.
1256 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1258 --- 1.8.4 2002/01/04
1260 Scan for ZOOM API. New object ZOOM_scanset. New functions
1261 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1262 ZOOM_scanset_destroy.
1264 New ZOOM function, ZOOM_connection_last_event, that returns type
1265 of last event (such as "receive data", "send data", "apdu received",
1268 New ZOOM option, schema, that specifies schema for retrieval.
1270 New CCL feature. Qualifiers can be aliases for one or more
1271 other qualifiers (if more than one is given, OR is used).
1273 ZOOM uses named result sets if target supports it.
1275 Two new YAZ client commands: . (dot, which sources a script of YAZ
1276 client commands), and ! (to execute shell command.). Implemented
1279 Working on Debian packages.
1281 --- 1.8.3 2001/11/19
1283 YAZ client enables named result sets only if target supports it.
1285 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1287 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1288 with key="host" to get same result.
1290 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1291 Function Z3950_resultset_record(s) returns references to records
1292 "owned" by resultset. To become owner use Z3950_record_clone.
1294 Function z_ext_record handles Extended Services. Thanks to
1297 --- 1.8.2 2001/11/12
1299 CCL Parser fix: ignore token comma when dealing with and-lists.
1301 Documentation updates for COMSTACK.
1303 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1304 Changed prototype Z3950_records. For some functions, int parameters
1305 were changed to size_t.
1307 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1310 New MARC decode/display function, marc_display_exl, which properly rejects
1311 non-ISO2709 records. YAZ client uses it.
1313 --- 1.8.1 2001/10/29
1315 Fix bug: local attribute set wasn't set correctly in PQF strings.
1319 * Old Z39.50 codecs no longer supported.
1321 Added ZOOM C binding. See http://zoom.z3950.org/
1323 Renamed states for COMSTACKs to avoid confusion with events.
1325 Implemented cs_look and proper cs_rcvconnect.
1327 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1329 Configure detects POSIX threads on OpenBSD.
1331 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1332 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1334 When error is returned from present handler, non-surrogate diagnostic
1335 is returned in present response (and fetch handler is no longer called).
1337 * Minor adjustments to pquery parser (PQF). Token characters may be
1338 escaped by using backslash (C-style).
1340 PQF parser allows string attribute values to be specified. For @attr,
1341 non-numeric characters after the equal-sign are treated as strings
1342 (e.g. @attr 9=title).
1344 CCL trunction character may be defined (@truncation in file)
1346 * function zget_ExtendedServicesRequest sets waitAction to
1347 waitIfPossible (was wait).
1349 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1352 CCL operator names may be set in field definition files (CCL_bibset).
1353 See ccl/bib1 for an example.
1355 Fixes in ASN.1 compiler for C++ compatibility.
1357 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1358 and "op_or" to avoid conflict with C++.
1360 Fixed problem with GNU readline detection on Redhat 7.0.
1362 Added step-size for Scan backend handler.
1364 Fixed bug that made the frontend server crash when no attribute
1365 set was specified for scan.
1367 Front-end server automatically switches to original working directory
1368 when installed as an NT service. Previously -w had to be specified to
1371 Added extended attributes for retrieval module (data1), so that data1
1372 records carry d1_readXML/SGML attributes. d1_read also supports
1373 null-data rules ( <tag/>)
1375 On UNIX when POSIX threads are available, a separate library libyazthread
1376 is created. Programmers should link with that library and the yaz library
1377 when using threads. The reason for the split was that some applications
1378 on Linux, such as Apache, doesn't work well when using shared objects that
1381 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1382 (or any frontend server) in SSL mode by specifying ssl: followed by
1383 address. Only tested on UNIX.
1385 Added feature for CCL module. Virtual structure s=al or s=ol generates
1386 and-list and or-list respectively instead of phrase search.
1390 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1391 log_mask_str. This was done to avoid name conflicts with other libraries
1392 (such as other PHP extensions).
1394 Added raw OID member for preferred record syntax (request_format_raw)
1395 and returned record syntax (output_format_raw) for backend fetch method.
1397 Config file yaz-config now accepts options so that it returns specific
1398 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1400 Shared library support for UNIX using GNU libtool.
1402 * Modified backend interface. Request/Response struct's replaced by
1403 one read/write C struct. For example bend_fetchrequest and
1404 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1405 Every handler - even search has to be registered in bend_init
1406 handler. This means that the YAZ library no longer refers to
1407 external functions and it makes it possible to make the whole
1408 thing a single DLL/SO.
1410 Added Segment handler for backend server.
1412 Added Zmbol/Zebra administrative functions to YAZ client.
1414 Threaded frontend server on UNIX (when POSIX Threads are available).
1415 Starting the server with option -T enables multi-threading.
1419 Added configure option --enable-comp/disable-comp to control use
1420 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1421 located in sub directory asn.
1423 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1424 in ${exec_prefix}/bin along with the other programs yaz-client and
1427 GNU automake used to maintain makefiles.
1429 Added several OID's.
1431 Changed retrieval module so that we can load records with no abstract
1432 syntax defined. Tagpaths in these records are fully composed of string
1435 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1439 On UNIX, the generated makefile now supports a proper 'make install'.
1440 The prefix can be set via GNU configure to set the install location
1441 (default is /usr/local).
1443 * YAZ programs client and ztest were renamed to yaz-client and
1444 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1445 locations, such as /usr/bin,/usr/local/bin,etc.
1447 * YAZ Header files were moved from include to include/yaz. YAZ Header
1448 files are referred to as include <yaz/log.h> rather than <log.h>.
1449 The YAZ include path (-I ..) is therefore the same as before. Programmers
1450 should update their #include statements or use -Ipath/include/yaz
1451 instead. The main motivation for doing this change is that YAZ header files
1452 can be installed in "standard" locations /usr/include,/usr/local/include
1453 without introducing conflicts, since ALL YAZ header files are stored
1454 in subdirectory yaz (under /usr/include for example).
1456 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1457 rather than project/workspace files. We switched because project files
1458 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1461 Changed name of logging function, logf, to yaz_log, to prevent name
1462 clash with some math-log functions. The YAZ header log.h defines logf
1463 to yaz_log (#define) so there should be no incompatibilities by this
1466 Added bend_start/bend_stop handlers for server. These handler are
1467 called on start/stop of server. For windows they are called whenever
1468 a service is started/stopped.
1470 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1471 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1472 in util/yc.tcl. The auto-generated C code structures are, in a few
1473 cases, incompatible with the old decoders. There are differences in the
1474 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1475 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1476 The preprocessor variable ASN_COMPILED is defined when the compiled
1477 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1478 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1479 wish to use the old encoders/decoders you can specify --disable-yc
1482 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1483 version so that it supports both new - and old version of DB Update
1485 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1486 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1487 change. The name parameter can be set to 0 in which no name is specified
1488 for the construction. The macros odr_implicit and odr_explicit sets name
1489 parameter to zero for the construction involved. New macros
1490 odr_implicit_tag and odr_explicit_tag are similar to the others,
1491 except that a name parameter is added. For programmers' that don't use
1492 ODR they probably only need to change the call to z_APDU and z_External.
1494 Added access control facility by interfacing the TCP wrapper library.
1495 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1496 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1497 name of the daemon and enables the access control as specified in
1498 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1500 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1501 den Dool <H.M.vdnDool@kub.nl>.
1503 Added reference ID parameter to most functions in server API - refer
1504 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1506 Changed name of ccl library to libccl.a (was ccl.a).
1508 Fixed bug in decoder for Explain (Category TargetInfo).
1510 Added support for GNU readline in client. Thanks to Jacob Poulsen
1511 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1513 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1514 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1515 IMPLEMENTATION! This change was made to the development version before
1516 the ZIG decided to retract the amendment. If any users MUST be
1517 compatible with the original Update definition, PLEASE CONTACT US, and
1518 we will include a separate definition corresponding to the old Update
1519 ES. Note that because of the change to the ASN.1 of the
1520 TaskPackageRecordStructure we cannot define a single structure that
1521 will support both versions.
1523 * Added const modifier to buffer parameter for some ODR/BER encoding
1524 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1525 completeWAIS, odr_dumpBER.
1527 Fixed bug in client.c which caused a crash when a scanResponse didn't
1528 contain positionOfTerm.
1530 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1531 * will cause an error in a client if a non-YAZ target sends both a
1532 * list of Scan entries and non-surrogate diagnostics.
1534 Retrieval module enhancements. Tag sets may be typed in the reference
1535 to it. From the .abs-file the "tagset" directive takes a third optional
1536 integer type for the tag set referenced. From a .tag-file the "include"
1537 directive takes a third optional type as well. The old "type" directive
1538 in the tag set itself is still recognized but acts as the default type
1541 Backend interface change. Individual Scan terms returned from bend_scan
1542 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1543 in include/backend.h.
1545 Retrieval module enhancements. Multiple tag sets and attribute sets may
1546 be specified in abstract syntax specs. Revised the error/warning for
1547 logging messages reported by the retrieval module when reading the
1550 Object Identifier system (oid_..) changed. The API is backwards
1551 compatible but the oid-routines now allocates new OID's when needed.
1552 Raw OID's may be specified in oid_getvalbyname.
1554 YAZ now uses GNU configure to generate Makefile(s).
1556 * Minor changes in some of the member names of DeleteResultSetRequest and
1557 DeleteResultSetResponse. See include/proto.h.
1559 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1560 and added member 'languages' in TargetInfo (which was missing).
1562 Changed the way attribute sets are handled in the retrieval
1563 module. These are now cached, just like the abstract syntaxes
1566 Changed YAZ so that it links with compiled ASN.1.
1568 Added Explain-schema definitions and mapping routines. The following
1569 Explain categories have been implemented: AttributeDetails,
1570 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1572 Fixed minor bug in Windows version of Server Library.
1574 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1576 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1578 Added EXTERNAL: UNIverse Resource Report (non-standard).
1580 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1581 ENUMERATED and SET OF.
1583 * Added 'const' to some of the char pointer arguments for the
1584 functions, data1_read_node, data1_getelementbytagname,
1585 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1588 Fixed bug in data1_insert_taggeddata - the last_child member of
1589 parent wasn't initialised.
1591 * Changed data1_read_record and data1_read_node so that the supplied
1592 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1593 doesn't refer to any parts of the "SGML"-buffer.
1595 Fixed bug in server library (Windows version of statserv_remove).
1597 * Changed code so that it compiles as C++. The type definition
1598 of Odr_fun which is a member of Odr_arm was changed. The result is,
1599 that an explicit typecast is needed for the fun pointer when
1600 using Odr_arm - as in:
1601 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1603 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1605 Implemented the new structured date and time definition as approved
1606 by the ZIG. Added schemaId element to the specificTag in Espec-1
1607 (also approved at the last ZIG). Thanks to RVDM.
1609 Added some Object identifiers (RVDM).
1611 Changed the Update Extended Service (RVDM).
1613 Added command "refid" to client which specifies referenceId for
1614 the following requests.
1616 Implemented extended service handling for server. See ztest.c
1617 for an example as well as backend.h. New handlers are registerd
1618 in the Init handler.
1620 * Changed interface for sort in server.
1622 Added new members to statserv_options_block. It allows a server
1623 to read options from another source than just the command line. Thanks
1624 to Charles Woodfield.
1626 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1627 renamed to zboolean. Some C++ compilers complained about the name.
1629 Minor changes to gils.abs. Added index 's' (sort) on title
1630 and date/time-last-modified.
1632 --- 1.4pl2 1998/1/30
1634 Fixed bug in server library regarding inetd mode (-i). This bug
1635 was introduced by release 1.4.
1637 --- 1.4pl1 1998/1/29
1639 Added sort facility in client and backend server interface.
1641 Fixed problem with dependencies in Makefile(s).
1643 Fixed bugs for encoders/decoders of extended services and
1646 Implemented sub-tree feature for schemas. Sub-trees are
1647 referenced in *.abs-files. See explain.abs for an example
1648 of the use of this feature.
1650 Modified bib1.att; local attributes for ANY didn't include
1651 ANY itself (only affects use of the retrieval module).
1653 Fixed bug in plain SGML reader in function data1_read_node:
1654 tags with prefix "var" was incorrectly interpreted as variants.
1656 Added feature "sub-schemas" to enable references to - and definitions
1657 of - group of elements.
1659 * Removed member parent from type data1_element (in data1.h).
1661 Implemented function odr_nullval() that returns the value of
1664 * Removed member num_children from data1_node (in data1.h).
1666 Made NT service interface part of the server library. The
1667 function statserv_main uses the NT service when required and
1668 calls the statserv_start / statserv_close routines.
1670 Routine zget_SearchRequest and zget_PresentRequest fills
1671 resultSetName/Id member with "default" instead of "Default".
1673 Fixed memory leak in server. Request queue member wasn't freed.
1675 Fixed nmem_exit so that memory is freed.
1679 Revised the CCL parser utility to be thread safe.
1681 Added function, oid_ent_to_oid, to replace the function
1682 oid_getoidbyent, which is not thread safe.
1684 * Added nmem_init and nmem_exit to initialize and release
1685 NMEM resources. Function nmem_init should be called once in the
1686 initial thread before NMEM/ODR is used. statserv.c and client.c
1687 have been changed accordingly. The change was necessary to make
1688 NMEM thread safe. The NMEM memory pool is shared amongst threads
1689 in a process. Unix-based applications will still work fine without
1692 Added NT Services interface for the the Z39.50 (statserv) Server.
1693 Refer to the ztest.c source on the usage.
1695 Windows 95/NT port using MSVC5.0. Project files are included in the
1698 * Defined new 'global' handle for the retrieval (data1) system. The
1699 new handled, data1_handle, describes the state of the data1 system.
1700 This handle is passed as first argument to virtually all
1701 data1 related routines. The functions data1_create and data1_destroy
1702 creates and destroys a data1 handle respectively.
1704 Added ODR encode stream member to all backend request structures
1705 init, search, scan etc. This stream should be used to allocate all
1706 memory used for the response when thread safe operation is needed.
1708 Changed the comstack utility, cs_addstr, to be thread safe. The
1709 returned hostname string returned by the function is now part the
1712 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1713 function. The cs_straddr takes a COMSTACK handle as argument, so this
1714 function must be used after cs_create and before bind/connect.
1715 This function is thread safe.
1717 Moved test server to 'ztest' directory - generic server code still
1718 in 'server' directory.
1720 Made prefix query (pquery.c) utility thread safe.
1722 Added new function modifier YAZ_EXPORT to 'export' public DLL
1723 functions when using windows (see include/yconfig.h).
1725 Added definitions to the OID database (util/oid.c) (RVDM).
1727 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1729 Added call to ccl_rpn_delete in client program.
1731 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1732 release of RPN structure.
1734 Added support for C++, headers uses extern "C" for public definitions.
1735 With input from RVDM.
1737 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1738 Thanks to Ronald van der Meer (RVDM).
1740 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1742 Added support for private extensions to the OID database
1743 (oid_setprivateoids()). Thanks to RVDM.
1745 Added optional, physical ANY (key replication)
1747 Fixed null-reference problem in GRS-1 output filter.
1749 Proximity operator added to Prefix Query Format (PQF).
1751 In test client command "base" accepts multiple databases.
1753 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1757 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1759 Smallish bug-fixes in the new encoders/decoders (explain).
1761 Bug fixed in DeleteRequest.
1763 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1765 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1767 Added SOIF syntax (using private OID for now) to retrieval module and client.
1769 Added Update extended service.
1771 Added SearchResult-1 additional info structure.
1773 Added optional CCL (ISO8777) interpreter as separate module. Available
1776 --- 1.2 1996/6/10 (1st anniversary release)
1778 Added Summary record syntax. Lightly tested.
1780 Added OPAC record syntax. Untested.
1782 Added ResourceReport service encoders/decoders. Untested.
1784 Fixed bug in z_Unit - wrong tagging on unitSystem.
1786 Fixed bug in the DiagRecs decoder.
1788 Added options for max PDU size and session timeout to frontend-server.
1790 Added documentation of query-language parsers and other supporting utilities.
1792 [frontend-server] Added Attribute set to the bend_scanrequest API.
1794 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1795 surrogate diagnostics were generated.
1797 [retrieval] Allow multiple local values for attribute.
1799 [retrieval] Allow multiple attributes per element in .abs files. index type.
1801 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1803 --- 1.1pl2 1996/4/10
1805 Minor changes, mostly specific to Zebra's requirements (retrieval)
1809 Repaired bug in frontend server when running multiple listening
1810 endpoints in dynamic mode.
1812 z_External() now won't break if a known, ASN.1 value comes encapsulated
1813 in an octet-string. The value will pass through unmodified in an Odr_oct.
1815 Added a bit of code to the demo client to decode & display
1816 ASN.1-structured records represented in the octet-aligned branch of
1817 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1819 Added z_ext_getentbyref() to the ASN module. Doc updated.
1821 * Completed the SCAN definition in the ASN module. This may break SCAN
1822 code based on older YAZ-versions at compile-time. The fix is easy -
1825 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1826 under the SCAN definition. Remember to initialize this, server-people.
1828 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1829 that this does not extend to ODR and ASN.
1831 Comstack allows insertion of established socket (primarily for
1832 inetd-operation of servers). Doc updated.
1834 Front-end server can now start from the inetd in TCP mode. Doc
1837 --- 1.0pl4 1996/1/24
1841 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1842 the rank and record number.
1844 Adjustments to the frontend server.
1846 Fixed diagnostic BER dumper. It ignored the file argument.
1850 Various changes to retrieval module.
1852 Changed the union discriminators of the protocol files from enums to
1853 ints paired with #defines.
1855 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1858 *Changed operator in the RPN structure to 'roperator', again to avoid a
1861 Fixed problems in Explain decoders/encoders.
1863 --- 1.0pl2 1995/12/6
1865 Memory bug in log module fixed.
1867 --- 1.0pl1 1995/12/5
1869 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1871 Bug in Explain DatabaseInfo module fixed.
1873 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1877 The shift to v1.0 signals that we now consider the *core* functionality
1878 of YAZ reasonably stable (the core being more or less equivalent to
1879 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1880 tested (Explain not at all - though that will happen soonish).
1882 Minor changes to code to support Windows port.
1884 Various minor changes after we're getting to use GRS-1 & co. more.
1886 Added Espec-1 format.
1888 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1889 of the protocol and it cannot be selected when encoding (maps into 'string'
1890 when decoding). Needed to talk to some servers.
1892 Demo client can request simple element set names.
1894 Added Diagnostic Format encoders/decoders.
1896 Added simple Close handling to frontend server (no hooks for resource
1897 reporting yet), and demonstration client.
1899 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1901 --- 1.0b3 1995/08/24
1903 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1904 handled incorrectly when records were requested in the searchResponse. This
1905 will only affect you if you use the frontend-server.
1907 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1908 Test-client will ask for and print GRS1. Ztest will return dummy records
1911 Added Explain encoders/decoders to the service-level API. Untested.
1913 Added Extended Services: Item Order encoders and decoders to the Service-
1914 level API. Untested. We could use a recent copy of the pertinent bits
1915 of the ILL protocol to add those bits.
1917 Added diagnostic format 1 encoders/decoders to the service-level API.
1920 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1921 odr_cons.c, which causes a more correct output.
1923 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1924 was always set to 0 when no records were requested in the searchRequest.
1926 * Added better external-handling. This shouldn't harm old code that
1927 *encodes* externals. It can break code that looks for a
1928 'single-ASN1-type' representation, since those types that are known
1929 are now decoded immediately. Look at the SUTRS sample code in
1930 seshigh.c and client.c. Documentation updated.
1932 Handling of structured records in bend_fetchresponse. Length -1 marks
1933 structured record, type is deduced from format field.
1935 --- 1.0b2 1995/06/27
1936 Fairly quick maintenance release to add SUTRS support.
1938 Fixed handling of SUTRS records in the demonstration client.
1940 * Added format field to the bend_fetchrequest and bend_fetchresponce
1941 structures of the backend API (frontend server). When the record is
1942 returned, the value of the format field is mapped to an OID. The
1943 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1944 of the record. The special value VAL_NONE in the bend_request means
1945 that no specific format was requested by the client. Documentation
1946 updated accordingly. Test server (ztest) will return a fixed dummy
1947 SUTRS record if your client requests SUTRS.
1949 Documentation updated accordingly.
1951 You can now set external libraries and RANLIB support in the top-level
1955 First public release.
