3 Added utilities yaz_{set,get}_esn to set/get element set name from
6 Removed the build of libyazthread.la. The libyaz.so is the threaded version
7 of YAZ and has been so since YAZ 2.1.10.
9 Implemented ZOOM_record_error which returns error information for
10 record (surrogate diagnostic).
14 Updates for SRU Update by Ko van der Sloot:
15 1. Changed name from "operation" to "action"
16 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
17 versions in the code, marked as 'backward compatible'.
18 3. Added diagnostics for SRU Update.
20 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
22 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
24 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
26 For GFS, fixed problem with SRU diagnostic 'First record position out of
27 range' being issued for 0 hits.
29 zoomtst10 part of Windows Build.
33 Implemented yaz_filepath_comp which splits a path into file path
34 components (required by Zebra 2.0.3+).
36 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
37 BSD inspired license until now so this should not have any real impact on
38 anybody. See http://www.opensource.org/licenses/bsd-license.php
40 Fixed bug #687: Missing log lines.
42 Fixed bug #678: CQL to PQF translation does not preserve double-quote
45 Fixed bug #689: SRU diagnostics to be added.
47 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
48 whether a connection is idle (no more work do do).
52 Change type of optval from long to int for invocation of setsockopt with
53 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
55 Added support for specifying the max log file size for the Generic
56 Frontend Server. The size is given with option -r.
60 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
64 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
67 Fixed bug in Generic Frontend Server that could cause a server to stop
68 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
70 For the generic frontend server, the maximum record size is used as maximum
71 size of incoming packages (SRU + Z39.50). The value until was previously
72 only used in Z39.50 Init negotiation and, later, in a session controlled
73 sizes of records returned. This is controlled using -k option. It can be
74 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
78 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
81 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
83 New option for yaz-marcdump -lpos=value which allows setting a portion
84 of MARC header to a certain value.
86 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
88 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
89 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
93 Fixed problem with SRU mode type (soap, get, post) for yaz-client
96 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
100 Fixed MARC ISO2709 encoding routines to deal with character set
103 Minor changes to GFS logging. Database included in search request log
106 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
107 cached/multiple records.
109 Shared libraries are built by default on Unix+configure.
111 Changed cql2pqf transformation to use a different evaluation order. The
112 new order is: always, relation, structure, position, truncation, index
113 and relationModifier. Old order was: always, relation, relationModifier,
114 structure, index, position, truncation. Note that the the latter ones
115 override former ones for identical attributes.. The new scheme means that
116 it is possible to override any existing attribute with a relationModifier.
117 And also that it is possible to override everything for the index rule
118 (except the ones listed in relationModifier). No order is perfect but this
119 one, we believe, covers more real cases.. The "always" should have been
120 called "default", since the attributes there can be overridden with all
123 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
124 compilation phase, but also for yaz-config --cflags output. This allows
125 us to have public headers with Libxml2 stuff in them . It should also,
126 eventually, make Libxml2 checks redundant in packages using YAZ, such
129 --- 2.1.22 2006/06/15
131 Changed SRU update structure bend_update_rr so that SRU diagnostics are
132 stored in uri, message and details.. Previously diagnostics were stored
133 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
134 compatibility.. but he's probably the only one affected, so.
136 Added support for CCL, compiled on the client side, in ZOOM-C. This
137 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
138 input; the resulting query objects can be used for for searching with
139 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
141 YAZ' configure searches for OpenSSL by default.
143 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
144 SL_CTX_use_certificate_file. See
145 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
146 for more info. Thanks to Ko van der Sloot.
148 --- 2.1.20 2006/06/02
150 Bug #600: SRU GET, POST support for yaz-client. Introduced
151 command 'sru' which selects method SOAP/GET/POST.
153 Allow missingValueAction to be specified for the sortspec string -
154 function yaz_sort_spec. By default, the missing value action is null.
155 Use ! to specify "abort". Use = followed by stringvalue to specify default
158 Ensured that Present-handler (if defined) is called in GFS before any call to
159 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
160 searchRetrieve requests.
162 Documentation for YAZ is now based on the Docbook XML/XSLT using
163 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
164 is no longer depending on jade/openjade or docbook-to-man scripts.
165 PDF is no longer part of the distribution - but can optionally be
166 made using DSSSL/jadetex or FOP.
168 Added retrieval handling support in Generic Frontend Server to support
169 conversion between MARC/XML as well as XSLTtransforms. See
170 etc/yazgfs.xml for an example.
172 Added Authentication support to Generic Frontend Server in SRU
173 mode. Authentication using HTTP Basic is supported, as is the use
174 of 'x-username' and 'x-password' parameters in the request itself.
176 Added support for a new character set MARC8s identical to MARC8 except
177 that it converts combined characters to single Unicode characters in the
178 Latin-1 range (when possible).
180 --- 2.1.18 2006/04/24
182 ASN.1 compiler 0.4: generates brief Doxygen file header for
183 generated .h/.c files.
185 Utility yaz_iconv now supports conversion to MARC-8.
187 New facilities for the MARC module. The reading - and writing of
188 content are separate methods for the yaz_marc_t handle. The following
189 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
190 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
191 format). Write functions have prefix yaz_marc_write_.. The existing
192 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
193 available. Removed support for OAI-MARC and simplexml (not the
194 simplexml from PHP5).
196 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
197 to be returned for this connection.
199 --- 2.1.16 2006/03/31
201 Allow multiple languages and charsets to be specified with
202 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
203 negcharset iso-8859-1,utf-8
205 Translation of proximity nodes from CQL into PQF now works.
207 Moved to automake 1.8, 1.9.
209 Added function yaz_log_set_handler which allows a log handler to be
210 installed. This handler will be called for all log messages. Output
211 to file is also produced; but that can be disabled by passing NULL
212 fname to yaz_log_init_file.
214 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
216 For SRW (including GFS), accept application/soap+xml as content-type
219 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
220 produces NO stylesheet reference even if a default stylesheet is specified
223 --- 2.1.14 2006/03/14
225 Updated Windows package to include yazd.dll + yazd.lib for the
226 Development component.
228 If the environment variable YAZ_LOG is set, then it is used as a
229 string indicating the default level of logging to use if not
230 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
231 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
232 used as before. So, for example, to omit warnings from YAZ logging,
235 cql_transform() now map structure and other attributes before indexes,
236 so that index-specific structures and other attributes can override
237 defaults. So now a combination of mapping specifications such as:
239 index.dc.date = 1=date-modified 4=5
240 does the right thing.
242 cql_transform() now also respects the "always" mapping specification,
243 which establishes an initial set of attributes to be used for all
244 terms except where overridden by more specific attributes associated
245 with the index, relation or modifier.
247 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
248 which mode to use; one of "post", "get" or "soap" (SRW, default).
250 Fixes for yaz_iconv routines: changed trie-based character set conversions
251 to use only non-negative values for bit fields due to Sun's C compiler not
252 supporting negative values.
254 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
255 sequences where not read correctly. Fix by Rustam Usmanov.
257 Updated win/makefile to use options, settings which makes things
258 compile with VS C 2005.
260 --- 2.1.12 2006/02/01
262 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
264 In ZOOM socket code, use select instead of poll on MacOSX.
266 ZOOM-C now support client-side compilation of CQL into RPN that is
267 sent to the server, enabling CQL to be used against all Z39.50
268 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
269 ZOOM_query object, and submit it using ZOOM_connection_search().
270 The CQL-to-RPN translation uses a configuration file, the name of
271 which must be specified in the Connection's "cqlfile" option.
273 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
274 function, which takes as its start-term parameter a ZOOM_query object
275 (which may have had either CQL or RPN set into it).
278 --- 2.1.10 2005/11/29
280 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
281 GFS to support this as well. Backend handler, bend_srw_update, does the
282 update work. Code contributed by Ko van der Sloot.
284 Allow retrieval of Search Result-1 information in ZOOM by the use of
285 options that are attached to a result set. ZOOM documentation updated
288 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
289 UTF-8 conversion. Patch by Raj Patel.
291 Added option -m to GFS to control formatting of timestamps in log file.
293 Added 'exit' as synonym for 'quit' in yaz-client
295 Added support for specifying SRW resultSetId + resultSetIdleTime in a
296 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
297 for the new members. Patch by Ko van der Sloot.
299 Added support for SRU POST. It is supported for content-type
300 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
302 Do not build the separate Multi-threaded (MT) library libyazthread.la.
303 Instead make the library libyaz.la multi-threaded. Threading as a whole
304 can still be disabled by configure option --disable-threads. Previosly,
305 with older GLIBCs there were problems with MT libs under Apache. This
306 has now been fixed a long time ago.
308 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
311 CQL module modified to be case insensitive for relations/indexes/operations.
313 Fixed bug in CQL transform code: incorrect value relationModifieder
316 Added 'show all' command for yaz-client which retrieves all results
319 Added new yaz-client, xmles, which takes a (private) OID and
320 a document to be sent as an extended service request.
322 Describe new yaz-client commands wait_response and set_auto_wait.
324 Increase TCP/IP listener backlog from 3 (which I am guessing was
325 copied from the SunOS manual entry way back when) so SOMAXCONN, so
326 that the socket will queue as many incoming connections as it's able
327 to handle ongoing connections. In other words, it will never now
328 refuse a connection that it would be able to handle merely because
329 it's not got around to accepting() enough of the pending connections
330 yet. This is the behaviour anyway under Linux, where the listen()
331 argument is ignored; but not under BSD and on systems such as
332 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
333 YAZ-based servers should now be uniform across operating systems in
336 yaz-marcdump uses 64-bit file access on some systems. This is enabled
337 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
338 This allows yaz-marcdump to read large MARC batches (>2 GB).
340 Modified all YAZ source files - except the source which is auto-generated
341 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
344 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
345 corresponding to the existing *_setl() function. These allow option
346 values containing arbitrary valuues.
348 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
349 ZOOM_resultset_sort() in new applications. Its behaviour is identical
350 except that it returns an indicator of whether or not the sort
351 criterion was accepted (0 for OK, -1 for invalid).
355 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
356 MARC output rather than returning "new" buffer.
358 yaz-client warns about unknown init options.
360 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
364 Added support for SRW sort in Generic Frontend Server. Patch
365 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
366 sortKeys - or NULL if none is provided.
368 Fixed bug #307: It was impossible to specify indefinite/no timeout
369 for ZOOM_event. Special timeout value -1 now means indefinite timeout
372 Added support for multiple languages and charsets to be specified in
373 ZOOM. Each charset/language is separated by a blank. If negotiation is
374 in effect in init-response, Option
375 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
376 Code based on patch by Vasiliy Osadchuk.
378 Fixed bug #306: infinite recursion that occurred when calling
379 yaz_log_level_init as the first call (before other log level or
382 Fixed bug in scan handling in front end server: if preferred-Position-In-
383 Response was non-present, a NULL pointer referece was performed.
387 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
388 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
389 now defined for all those error codes. So instead of putting 109 in
390 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
391 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
393 Modified the yaz-marcdump utility to skip garbage bytes between MARC
396 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
398 Program yaz-client now exits and produces an error message if multiple
399 Z39.50 servers are specified on the command line (none or one allowed
402 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
407 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
409 Fixed bug #272: Preserve spacing for CCL terms.
413 Added support for virtual hosts and multiple backend servers for
414 the YAZ frontend server. The configution is XML based and
415 support specificition of CQL to RPN mappings and explain information.
416 See section "Virtual Hosts" in the YAZ manual.
418 Extended OPAC display utility. OPAC display utility renders
419 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
420 to supplement yaz_marc_decode_wrbuf.
422 Fixed a bug in MARC decoder that could caused it to crash for some
423 invalid MARC records. More diagnostics and warnings where added in
424 XML output (warnings, etc are stored in comments).
426 --- 2.0.34 2005/02/08
428 Fixes for UNIX domain sockets. Bug #261.
430 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
432 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
433 Added yaz_marc_subfield_str which defines subfield lead string which is
434 used in YAZ_MARC_LINE format. Default string is blank+$. Added
435 yaz_marc_endline_str which defines end of fields string used in
436 YAZ_MARC_LINE format. Default string is newline.
438 Experimental support for MarcXChange. This format can be produced
439 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
440 http://www.bs.dk/standards/MarcXchange.xsd
442 Added yaz-client commands scansize that sets maximum number of
443 entries to be returned by scan.
445 --- 2.0.32 2005/01/11
447 Added support for SRW scan in yaz-client and Generic Frontend Server.
449 * Added whereInList member to SRW Scan Term.
451 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
453 Fixed NMEM system to return aligned blocks on the smallest boundaries
454 that are suitably aligned for all possible types on the particular
455 architecture YAZ is being built for.
457 --- 2.0.30 2005/01/04
459 Fixed numerious warnings that was issued with newer versions of GCC.
461 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
462 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
465 Make YAZ Generic Frontend Server slightly faster.
467 Enhance (and reduce) logging for Generic Frontend Server.
469 Revert YAZ log system so that it flushes every write operation
470 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
472 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
473 instead of LOG_, due to name clash with syslog(3). LOG_ are still
474 present. New applications should define YAZ_USE_NEW_LOG=1 - this
475 will effectively disable old definitions.
477 --- 2.0.28 2004/11/09
479 Added yaz_log_time_format which specifies log format using
482 Added yaz_log_module_level which returns mask for a module. Value
483 is non-zero mask a if module is enabled; zero if disabled.
485 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
486 in include/yaz/cql.h.
488 Fixed bug #176: Dont throw diagnostics on empty SRU args.
490 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
492 Fixed bug #172: RPM builds does not enable SSL.
494 Doxyfile.in part of dist. Doxyfile generated by configure.
496 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
497 are given and the corresponding component does not exist.
499 Extend CCL documentation in YAZ reference. Describe r=r.
501 --- 2.0.26 2004/10/01
503 Fixed MARC->MARCXML conversion to properly deal with
504 fields, subfields, indicators having non-ASCII characters.
506 Fixed MARC->MARCXML conversion so that ASCII control characters
507 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
510 Added YAZ GFS support for conversion from Z39.50 surrogate
511 diagnostics to SRW surrogate diagnostics.
513 Bug fix: YAZ GFS did not return schema in explainResponse.
515 --- 2.0.25 2004/09/30
517 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
518 now converts recordSchema to elementSetName as well as schema URI.
520 Fixed bug in COMSTACK that prevented HTTP request packages from being
523 --- 2.0.24 2004/09/29
525 Added CCL facility r=r "range" which is similar to r=o "ordered" but
526 does not require white-space before and after the dash in a range, e.g.
527 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
530 Fixed a few AC_TRY_LINK configure tests that did not operate properly
531 due to new GCC removing "redundant" code.
533 Added yaz-client commands scanpos and scanstep that sets preferred
534 position and step-size for scan.
536 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
538 Added CCL utility ccl_qual_buf which parses one or more CCL
539 spec lines in a buffer.
541 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
542 of name and value - ignoring empty lines and comments.
544 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
546 Added odr_get_element_path which returns current element path for an
547 ODR handle. This utility is useful in error handling or user-defined
550 Added ODR_PRINT utility odr_set_stream which is is a more generic
551 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
552 to a write function and pointer to close function. The close function - if
553 non-NULL - will be called during odr_destroy.
555 Fixed bug in CCL parser where truncation char was not removed from
556 right side when truncation=both was in effect.
558 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
561 --- 2.0.23 2004/08/11
563 Fix buffer overrun in CQL parser when dealing with proximity (%).
565 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
566 to UTF-8/UCS conversion is now only based on codetables.xml.
568 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
570 --- 2.0.22 2004/08/06
572 Add support for more "commit changes" in ZOOM (uses Extended Services).
574 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
577 Yet another small fix for configure of SSL.
579 --- 2.0.21 2004/05/14
581 Fix SSL libs for configure when --with-openssl=DIR is given.
583 --- 2.0.20 2004/05/10
585 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
587 SSL comstack now uses yaz.pem certificate file on server side
588 by default. Certificate filename can be configured by calling
589 comstack function cs_set_ssl_certificate_file before cs_bind is used.
591 Fix bug regarding multiple calls to ZOOM_connection_connect.
593 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
595 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
596 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
598 ZOOM now allows inspection of X509 peer certificate for verification.
599 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
601 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
602 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
603 as "modular" but it simplifies things.
605 Added cs_get_peer_certificate to that returns peer X509 PEM.
607 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
608 NULL if SSL is unavailable.
610 Documentation about MARC decoding tools.
612 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
614 --- 2.0.19 2004/03/30
616 Rename CHANGELOG to NEWS to follow GNU style packing.
618 Fix bug with missing initialization of member in init_diagnostics.
619 This bug affects threaded version of GFS server.
621 --- 2.0.18 2004/03/20
623 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
626 Ensure zlib.dll is packed with Windows install.
628 --- 2.0.17 2004/03/17
630 Fix encoding of xsd:string to use text instead of CDATA.
632 Fix endless loop in CQL parser with unbalanced ".
634 Use a more compact way to store MARC-8 conversion tables.
636 --- 2.0.16 2004/03/16 Debian only
638 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
641 Update CQL parser to use new CQL 1.1 modifiers for booleans and
646 --- 2.0.15 2004/03/01
648 Another fix for decoding of XML packed records.
650 --- 2.0.14 2004/02/25
652 Fixes for Chunked encoding. White space not ignored after length spec.
654 Update NS and use default NS for SRW diagnostic elements.
656 --- 2.0.13 2004/02/23
658 Implement ZOOM_resultset_cache_reset which resets record cache.
660 Implement ZOOM_resultset_sort which sorts a result set.
662 Implement chunked HTTP transfer.
664 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
666 --- 2.0.12 2004/02/16
668 Added member 'schema' to bend_explain_rr structure so that backend
669 can specify explain record identifier. Defaults to Zeerex 2.0.
671 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
673 --- 2.0.11 2004/02/16
675 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
678 Added init command for yaz-client which sends "extra" init request.
680 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
681 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
683 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
685 Make ZOOM error code for "invalid query".
687 Fixed compilation for SSL which wasn't properly enabled for all platforms.
689 --- 2.0.10 2004/02/05
691 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
694 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
696 Added option -p <file> to make Generic Frontend Server to write PID file.
698 Added option -D to put Generic Frontend Server in background on its own.
700 Make ZOOM C recognize option "password". If unset, "pass" is used
701 (for backwards compatibility).
703 Fixed a bug in Generic Frontend Server that could make it crash if a
704 client sets characterSetNegotation bit, but didn't pass negotiation stuff
707 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
708 Must be issued before open, in order to be in effect.
710 --- 2.0.9-6 2004/01/12 Debian/Windows
712 Make the SRU server more picky WRT unknown params, etc.
714 Bug fix: ZOOM scan response didn't return displayTerm - when present.
716 New YAZ client command, options, that sets Z39.50 options.
718 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
719 options from a string of tokens (one token for each option bit).
721 Update SRW diagnostic code messages.
723 --- 2.0.9-5 2004/01/07 Debian/Windows
725 Handle user defined stylesheet for SRW/SRU.
727 --- 2.0.9-4 2004/01/06 Debian/Windows
729 Fix bug in decoding of Content-Length.
731 --- 2.0.9-3 2004/01/06 Debian/Windows
733 Fix a bug with decoding of XML packed records.
735 --- 2.0.9-2 2004/01/05 Debian only
737 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
739 Fix bug in SRW/SRU diagnostics decoding.
743 Fixed bug in Generic Frontend Server which could drop records exceeding
744 preferred message size. Reported and fixed by Irina Dijour.
746 Fixed calculation of package size for structured records in Generic
747 Frontend Server. Reported and fixed by Irina Dijour.
749 Fixed namespace for SRW/SRU diagnostics.
751 Fixed SEGV in yaz-client that occured for HTTP connection errors.
755 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
756 this version is incompatible with version 1.0 and older YAZ SRW/SRU
759 CQL changes to reflect recent changes to the specification:
760 * Documentation talks about context sets instead of index sets.
761 * Documentation talks about indexes instead of qualifiers.
762 * The CQL-to-PQF transformer's configuration file now uses
763 "index.set.name = <attributes>" instead of the old form
764 "qualifier.set.name = <attributes>". (Both forms are still
765 understood but the latter is deprecated.)
766 * CQL terms with no explicit index specified are now interpreted as
767 cql.serverChoice instead of srw.serverChoice (which of course
768 behaves exactly the same.)
772 MARC conversion can now generate ISO2709 output in another
773 character set. yaz-marcdump uses this facility if you invoke it
776 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
777 functions from there can be used from C++.
781 Frontend server now transfers memory from decoded packages to stream
784 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
785 references to show up.
787 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
788 the ZOOM Abstract API. The older names for the same options are still
789 also supported for the benefit of old applications.
791 ZOOM-C supports "implementationId" and "implementationVersion" options
792 to go along with "implementationName". These allow the user code to
793 specify identification strings to be sent to servers.
794 Add OID for the new ExtLite attribute set.
796 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
797 as requested/supplid by Ere Maijala <ere@atp.fi>
799 For generic frontend server, reverse the order of
800 "toolkit-supplied / application-supplied" strings sent as implementationId,
801 Name and Version. Also, remove the spaces around the slash. This brings
802 the GFS in line with the behaviour of ZOOM-C on the client side.
804 Add function ZOOM_scanset_display_term.
806 yaz-client shows scan displayTerm if present.
808 Utility yaz-iconv is now installed by default along with the man page
811 Extend configure check for OpenSSL to use pkg-config where available (such
814 Incorporate patch by Morten Bogeskov which allows a Unix file socket
815 server to specify uid/gid/mask for socket using the format
816 unix:[user=uid,][group=gid,][umask=mask,]file=path
817 If file= is omitted the existing format is assumed, e.g.
819 in which case the mask is 0666 (rw for everybody).
821 Major restructure of YAZ source. All source in libyaz is in src directory.
822 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
823 util (utility programs such as ASN.1 compiler, yaz-marcdump).
825 Added man page for utility yaz-marcdump (used to be called marcdump).
826 yaz-marcdump is installed by 'make install'.
828 Fixed a memory leak in Generic Frontend Server that occurred when decoding
829 of incoming package failed.
831 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
833 Change prototype of odr_perror: add const to message string.
835 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
837 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
838 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
839 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
840 DNS lookup. There should not be any compatibility problems with this
841 assuming that blocking=1 or 0 is used.
843 Fix bad reference in UNIX comstack in function cs_addrstr.
845 Fix for compilation on AIX.
847 The generic front-end server (server/seshigh.c) now supports returning
848 Init diagnostics to the client in User-information-field, in
849 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
854 Allow any CQL relation (not just all,any,exact,scr).
856 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
857 that features the same UI.
859 Implemented command update0 in YAZ client which is equivalent to
860 update but uses old of Ext Update ASN.1.
862 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
863 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
864 Previously no OID was used for this info.
866 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
867 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
868 returns 'malformed search term' otherwise.
870 SortResponse member resultCount now set to NULL in sort handler of
873 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
876 Add three new utility functions for translating OIDs between various
877 formats -- symbolic name such as "Usmarc", minus-1-terminated int
878 arrays and dotted strings such as "1.2.840.10003.9.5.1":
879 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
880 char *oid_to_dotstring(const int *oid, char *oidbuf);
881 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
883 Reverted modifications for ES Update definition for z_IU0Update
884 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
885 is back to YAZ 2.0.2.
887 String value attributes for CCL parser.
889 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
890 which their FirstSearch server returns in Init responses, sometimes
891 carrying useful diagnostic information when Init fails. This has the
892 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
893 "z39.50/oclcui.asn", where its definition is somewhat different from
894 what OCLC document on their web-site, as required to interoperate with
897 Support for anonymous authentication in yaz-client. Use the command
900 * Fix the OID of the Index Data-local "admin" Extended Service from
901 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
902 the 1000, which indicates a locally-defined OID, was a mistake.
906 Fix CCL directive @case handling so that it affects string match for
907 both CCL keywords and qualifiers.
909 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
910 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
911 Decoder has been updated with ASN.1 changes as listed in
912 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
913 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
914 z_IUUpdate, remains unchanged.
916 ZOOM_record_get may now return a record in a specific character set.
917 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
918 "from" is the character set of record as returned by target. "to" is
919 the character set to be returned. If omitted, "to" is UTF-8.
921 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
923 New ODR utility, odr_getelement, which returns name of element for
924 which encoding/decoding failed.
926 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
927 in cases where a required element was omitted.
929 Bug fix: some MARC8 sequences were not converted.
931 New ZOOM option "step" which specifies number of records to be
932 retrieved in one chunk. Used in conjunction with "start" and "count".
934 SRW support for yaz-client. Use scheme http: to use it, e.g.
937 yaz-client no longer does (un)intelligent character set conversions
938 by default. Can be enabled with charset and marc_charset commands.
940 xmalloc trace fix for 64-bit systems such as DEC alpha.
942 Solaris 2.6 compile fix.
944 New function, cql_strerror() translates SRW error codes, as returned
945 by cql_transform_error(), into human-readable English strings. Used
946 in yaz-client diagnostics when appropriate.
948 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
949 converts it into a type-1 query which is sent to the server. This
950 makes CQL available for use with all Z-servers, as opposed to the tiny
951 minority that can handle CQL queries themselves.
955 New Debian package layout similar to the Redhat Package layout.
957 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
958 and search result respectively.
962 Redhat package is now several packages: libyaz (runtime libraries),
963 libyaz-devel (development and documentation, and yaz (utility programs).
964 Package spec file by Morten Bøgeskov.
966 New member 'schema' in struct bend_fetch_rr which the name of requested
967 schema (SRW/SRU) for record (or NULL if none was given). The fetch
968 handler MAY set this to reflect the schema of the returned record.
970 New member 'display_term' in struct scan_entry. GFS now sets member entries
971 and allocates scan entries to be filled by user scan handler. In previous
972 version, entries member was allocated by the scan handler. That still works,
973 but the GFS will ignore member display_term - assuming it was NOT set by
974 the handler. The fact that the GFS now allocates the entries both allows
975 for new members and makes a scan handler easier to write.
977 Fix CQL lex buffer overflow.
979 SRW/SRU recordPacking. For SRW default recordPacking is string. For
980 SRU default recordPacking is string.
982 SRU protocol support for frontend server.
984 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
986 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
988 Added scan for the ZOOM shell (zoomsh).
992 * String Identifers for Schemas (Amendment 5).
993 http://lcweb.loc.gov/z3950/agency/amend/am5.html
994 Old definition for schema
995 Odr_oid *schema; /* OPT */
1000 Z_InternationalString *uri;
1001 #define Z_Schema_oid 1
1002 #define Z_Schema_uri 2
1005 * resultCount parameter to Sort Response (Amendment 1).
1006 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1008 Support for SRW 1.0 over HTTP. This is an optional feature and
1009 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1012 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1013 on the same port. SRW SearchRetrieveRequests are mapped
1014 to bend_init,bend_search,bend_fetch,bend_close.
1016 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1018 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1019 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1021 ZOOM connections are SRW based if schem http is used for hostname
1022 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1023 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1025 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1026 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1027 distance=n, order=true/false, relation=le, prox unit=word. If
1028 n is omitted, distance 1 is used.
1030 Fixed problem with C compiler include path in wrong order.
1032 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1033 on Solaris. Patch from Ko van der Sloot.
1035 New MARC decode API. All new functions operate on a yaz_marc_t
1036 handle. The most important new functions are: yaz_marc_create,
1037 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1038 decode and destroy respectively. Decoder can produce formats
1039 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1040 include/yaz/marcdisp.h.
1042 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1043 to UTF-8, UCS-32, wchar_t or Latin-1.
1045 * Prototypes for yaz_iconv_-functions moved to separate header
1046 include/yaz/yaz-iconv.h.
1048 Make a few private functions 'static' in unix.c. This prevents
1049 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1051 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1052 are set when Init Response is received.
1054 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1055 but returns diagnostic set as well.
1057 New function yaz_strerror which is a portable wrapper for
1058 strerror/strerror_r/GetLastMessage.
1060 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1061 is returned for MARC. If type is "oai", then OAI MARC is returned.
1063 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1066 --- 1.9.2 2002/11/26
1068 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1070 Fix bad race conditions on SIGTERM and terminate gracefully in
1073 Move retrieval (data1) module to Zebra since nobody seems to be
1076 Add GRS-1 render for ZOOM using same format as yaz-client.
1078 --- 1.9.1 2002/10/05
1080 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1082 Fix broken ESpec handling in data1 module.
1084 SGML reader parses comments and makes them part of the data1 tree.
1086 Added several type casts so that YAZ compiles as C++ code.
1088 ZOOM didn't handle PDU encoding failures properly.
1090 Added more Bib-1 diagnostics (approved extensions).
1092 GNU configure: better check for iconv.
1094 More portable use of accept, getpeername. Check for socklen_t. Use
1095 int/size_t if socklen_t is not defined.
1099 PQF parser rejects bad queries - including those with extra
1100 characters in them. PQF parser used to silently ignore that.
1101 Cleaner API for PQF added, which allows you to get detailed
1102 error information for bad queries (see yaz/pquery.h).
1104 Fixed bug in ZOOM_record_get for type "database".
1106 Implemented mini iconv library supporting conversions between
1107 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1109 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1111 --- 1.8.9 2002/08/20
1113 Fixed ZOOM C record cache so that preferredRecordSyntax and
1114 elementSetName is used to check for already fetched records.
1116 --- 1.8.8 2002/08/02
1118 Added three members in bend_initrequest structure to facilitate
1119 character set negotiation.
1121 Fixed a bug in frontend server that could cause indefinite
1122 loops under rare conditions.
1124 Revised character set utilities (charneg.h) so that encoding
1125 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1127 For PQF, directive @term <type> sets term type for Scan/Search.
1128 Here <type> is general, string, numeric, null. The term type
1129 is inherited - just like @attr.
1131 New call odr_set_charset that sets character set conversion for
1132 international-strings on a ODR stream. Prototype is:
1133 int odr_set_charset(ODR o, const char *to, const char *from);
1134 The InternationalString is still represented as C string in YAZ
1135 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1136 won't). On the protocol level, you can use any encoding.
1138 Support for UNIX sockets in ZOOM.
1140 Solaris recv sometimes returns errno == ENOENT. It is treated as
1141 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1143 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1144 both client and server. Code by Morten Bøgeskov.
1146 --- 1.8.7 2002/05/22
1148 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1149 that they can be used directly from Visual Basic. You must recompile
1150 your windows APP if you're using ZOOM.
1152 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1153 Commands "lang" and "charset" sets language and character set respectively.
1154 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1155 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1157 Attributes from multiple CCL fields may be OR'ed rather than merged
1158 using directive "@field or". Fields are still merged by default -
1159 equivalent to "@field merge".
1161 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1164 Fixed bug in zget for parameter ExtendedServicesResponse.
1168 --- 1.8.6 2002/03/25
1170 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1172 Client displays USR.1:SearchResult-1 (hits per term).
1174 Additional Search Info for search in Generic Frontend Server.
1176 Fixed CCL parsing of "field=s".
1178 WIN32 installer - using the excellent NSIS software from nullsoft.
1180 Fixed CCL parsing of "field = - <number>".
1182 Added function yaz_marc_decode that decodes MARC for line mode
1183 display or XML (similar to that used by JZKit).
1185 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1186 Z39.50. But ISO/ILL was, however.
1188 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1189 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1191 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1192 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1194 --- 1.8.5 2002/02/03
1196 New YAZ client features: Command completion and new commands:
1197 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1198 Code provided by Jacob Poulsen.
1200 New call oid_trav, that visits all registered OIDs via callback.
1202 Function ZOOM_record_get now returns const char pointer rather than
1203 void pointer. It saves a lot of type casts.
1205 For YAZ client, command "auth" now allows you to set authentication
1206 in IdPass style. It is enabled when three tokens are given - order
1207 is user, group and password.
1209 Fix memory leaks in MARC record handling for ZOOM.
1211 New option for YAZ client, -k <kilobytes> that sets
1212 maximum record size. Similar to -k option for generic frontend
1213 server and yaz-ztest.
1215 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1217 Prefix query parser reports "fail" when bad attribute set is given.
1219 Fix in MARC decoder. Proximity logging. Fix for attribute set
1220 in scan handler for server. Patches by Shigeru Ishida.
1222 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1225 Configure option --with-openssl=<dir> now works when a directory is
1226 specified. Patch provided by Morten Bøgeskov.
1228 New option for YAZ client, -u <auth>, that sets authentication.
1230 ZOOM fix: error information was sometimes "missing", since error
1231 was cleared/reset too when it shouldn't.
1233 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1235 --- 1.8.4 2002/01/04
1237 Scan for ZOOM API. New object ZOOM_scanset. New functions
1238 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1239 ZOOM_scanset_destroy.
1241 New ZOOM function, ZOOM_connection_last_event, that returns type
1242 of last event (such as "receive data", "send data", "apdu received",
1245 New ZOOM option, schema, that specifies schema for retrieval.
1247 New CCL feature. Qualifiers can be aliases for one or more
1248 other qualifiers (if more than one is given, OR is used).
1250 ZOOM uses named result sets if target supports it.
1252 Two new YAZ client commands: . (dot, which sources a script of YAZ
1253 client commands), and ! (to execute shell command.). Implemented
1256 Working on Debian packages.
1258 --- 1.8.3 2001/11/19
1260 YAZ client enables named result sets only if target supports it.
1262 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1264 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1265 with key="host" to get same result.
1267 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1268 Function Z3950_resultset_record(s) returns references to records
1269 "owned" by resultset. To become owner use Z3950_record_clone.
1271 Function z_ext_record handles Extended Services. Thanks to
1274 --- 1.8.2 2001/11/12
1276 CCL Parser fix: ignore token comma when dealing with and-lists.
1278 Documentation updates for COMSTACK.
1280 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1281 Changed prototype Z3950_records. For some functions, int parameters
1282 were changed to size_t.
1284 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1287 New MARC decode/display function, marc_display_exl, which properly rejects
1288 non-ISO2709 records. YAZ client uses it.
1290 --- 1.8.1 2001/10/29
1292 Fix bug: local attribute set wasn't set correctly in PQF strings.
1296 * Old Z39.50 codecs no longer supported.
1298 Added ZOOM C binding. See http://zoom.z3950.org/
1300 Renamed states for COMSTACKs to avoid confusion with events.
1302 Implemented cs_look and proper cs_rcvconnect.
1304 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1306 Configure detects POSIX threads on OpenBSD.
1308 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1309 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1311 When error is returned from present handler, non-surrogate diagnostic
1312 is returned in present response (and fetch handler is no longer called).
1314 * Minor adjustments to pquery parser (PQF). Token characters may be
1315 escaped by using backslash (C-style).
1317 PQF parser allows string attribute values to be specified. For @attr,
1318 non-numeric characters after the equal-sign are treated as strings
1319 (e.g. @attr 9=title).
1321 CCL trunction character may be defined (@truncation in file)
1323 * function zget_ExtendedServicesRequest sets waitAction to
1324 waitIfPossible (was wait).
1326 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1329 CCL operator names may be set in field definition files (CCL_bibset).
1330 See ccl/bib1 for an example.
1332 Fixes in ASN.1 compiler for C++ compatibility.
1334 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1335 and "op_or" to avoid conflict with C++.
1337 Fixed problem with GNU readline detection on Redhat 7.0.
1339 Added step-size for Scan backend handler.
1341 Fixed bug that made the frontend server crash when no attribute
1342 set was specified for scan.
1344 Front-end server automatically switches to original working directory
1345 when installed as an NT service. Previously -w had to be specified to
1348 Added extended attributes for retrieval module (data1), so that data1
1349 records carry d1_readXML/SGML attributes. d1_read also supports
1350 null-data rules ( <tag/>)
1352 On UNIX when POSIX threads are available, a separate library libyazthread
1353 is created. Programmers should link with that library and the yaz library
1354 when using threads. The reason for the split was that some applications
1355 on Linux, such as Apache, doesn't work well when using shared objects that
1358 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1359 (or any frontend server) in SSL mode by specifying ssl: followed by
1360 address. Only tested on UNIX.
1362 Added feature for CCL module. Virtual structure s=al or s=ol generates
1363 and-list and or-list respectively instead of phrase search.
1367 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1368 log_mask_str. This was done to avoid name conflicts with other libraries
1369 (such as other PHP extensions).
1371 Added raw OID member for preferred record syntax (request_format_raw)
1372 and returned record syntax (output_format_raw) for backend fetch method.
1374 Config file yaz-config now accepts options so that it returns specific
1375 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1377 Shared library support for UNIX using GNU libtool.
1379 * Modified backend interface. Request/Response struct's replaced by
1380 one read/write C struct. For example bend_fetchrequest and
1381 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1382 Every handler - even search has to be registered in bend_init
1383 handler. This means that the YAZ library no longer refers to
1384 external functions and it makes it possible to make the whole
1385 thing a single DLL/SO.
1387 Added Segment handler for backend server.
1389 Added Zmbol/Zebra administrative functions to YAZ client.
1391 Threaded frontend server on UNIX (when POSIX Threads are available).
1392 Starting the server with option -T enables multi-threading.
1396 Added configure option --enable-comp/disable-comp to control use
1397 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1398 located in sub directory asn.
1400 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1401 in ${exec_prefix}/bin along with the other programs yaz-client and
1404 GNU automake used to maintain makefiles.
1406 Added several OID's.
1408 Changed retrieval module so that we can load records with no abstract
1409 syntax defined. Tagpaths in these records are fully composed of string
1412 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1416 On UNIX, the generated makefile now supports a proper 'make install'.
1417 The prefix can be set via GNU configure to set the install location
1418 (default is /usr/local).
1420 * YAZ programs client and ztest were renamed to yaz-client and
1421 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1422 locations, such as /usr/bin,/usr/local/bin,etc.
1424 * YAZ Header files were moved from include to include/yaz. YAZ Header
1425 files are referred to as include <yaz/log.h> rather than <log.h>.
1426 The YAZ include path (-I ..) is therefore the same as before. Programmers
1427 should update their #include statements or use -Ipath/include/yaz
1428 instead. The main motivation for doing this change is that YAZ header files
1429 can be installed in "standard" locations /usr/include,/usr/local/include
1430 without introducing conflicts, since ALL YAZ header files are stored
1431 in subdirectory yaz (under /usr/include for example).
1433 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1434 rather than project/workspace files. We switched because project files
1435 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1438 Changed name of logging function, logf, to yaz_log, to prevent name
1439 clash with some math-log functions. The YAZ header log.h defines logf
1440 to yaz_log (#define) so there should be no incompatibilities by this
1443 Added bend_start/bend_stop handlers for server. These handler are
1444 called on start/stop of server. For windows they are called whenever
1445 a service is started/stopped.
1447 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1448 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1449 in util/yc.tcl. The auto-generated C code structures are, in a few
1450 cases, incompatible with the old decoders. There are differences in the
1451 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1452 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1453 The preprocessor variable ASN_COMPILED is defined when the compiled
1454 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1455 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1456 wish to use the old encoders/decoders you can specify --disable-yc
1459 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1460 version so that it supports both new - and old version of DB Update
1462 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1463 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1464 change. The name parameter can be set to 0 in which no name is specified
1465 for the construction. The macros odr_implicit and odr_explicit sets name
1466 parameter to zero for the construction involved. New macros
1467 odr_implicit_tag and odr_explicit_tag are similar to the others,
1468 except that a name parameter is added. For programmers' that don't use
1469 ODR they probably only need to change the call to z_APDU and z_External.
1471 Added access control facility by interfacing the TCP wrapper library.
1472 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1473 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1474 name of the daemon and enables the access control as specified in
1475 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1477 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1478 den Dool <H.M.vdnDool@kub.nl>.
1480 Added reference ID parameter to most functions in server API - refer
1481 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1483 Changed name of ccl library to libccl.a (was ccl.a).
1485 Fixed bug in decoder for Explain (Category TargetInfo).
1487 Added support for GNU readline in client. Thanks to Jacob Poulsen
1488 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1490 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1491 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1492 IMPLEMENTATION! This change was made to the development version before
1493 the ZIG decided to retract the amendment. If any users MUST be
1494 compatible with the original Update definition, PLEASE CONTACT US, and
1495 we will include a separate definition corresponding to the old Update
1496 ES. Note that because of the change to the ASN.1 of the
1497 TaskPackageRecordStructure we cannot define a single structure that
1498 will support both versions.
1500 * Added const modifier to buffer parameter for some ODR/BER encoding
1501 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1502 completeWAIS, odr_dumpBER.
1504 Fixed bug in client.c which caused a crash when a scanResponse didn't
1505 contain positionOfTerm.
1507 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1508 * will cause an error in a client if a non-YAZ target sends both a
1509 * list of Scan entries and non-surrogate diagnostics.
1511 Retrieval module enhancements. Tag sets may be typed in the reference
1512 to it. From the .abs-file the "tagset" directive takes a third optional
1513 integer type for the tag set referenced. From a .tag-file the "include"
1514 directive takes a third optional type as well. The old "type" directive
1515 in the tag set itself is still recognized but acts as the default type
1518 Backend interface change. Individual Scan terms returned from bend_scan
1519 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1520 in include/backend.h.
1522 Retrieval module enhancements. Multiple tag sets and attribute sets may
1523 be specified in abstract syntax specs. Revised the error/warning for
1524 logging messages reported by the retrieval module when reading the
1527 Object Identifier system (oid_..) changed. The API is backwards
1528 compatible but the oid-routines now allocates new OID's when needed.
1529 Raw OID's may be specified in oid_getvalbyname.
1531 YAZ now uses GNU configure to generate Makefile(s).
1533 * Minor changes in some of the member names of DeleteResultSetRequest and
1534 DeleteResultSetResponse. See include/proto.h.
1536 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1537 and added member 'languages' in TargetInfo (which was missing).
1539 Changed the way attribute sets are handled in the retrieval
1540 module. These are now cached, just like the abstract syntaxes
1543 Changed YAZ so that it links with compiled ASN.1.
1545 Added Explain-schema definitions and mapping routines. The following
1546 Explain categories have been implemented: AttributeDetails,
1547 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1549 Fixed minor bug in Windows version of Server Library.
1551 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1553 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1555 Added EXTERNAL: UNIverse Resource Report (non-standard).
1557 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1558 ENUMERATED and SET OF.
1560 * Added 'const' to some of the char pointer arguments for the
1561 functions, data1_read_node, data1_getelementbytagname,
1562 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1565 Fixed bug in data1_insert_taggeddata - the last_child member of
1566 parent wasn't initialised.
1568 * Changed data1_read_record and data1_read_node so that the supplied
1569 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1570 doesn't refer to any parts of the "SGML"-buffer.
1572 Fixed bug in server library (Windows version of statserv_remove).
1574 * Changed code so that it compiles as C++. The type definition
1575 of Odr_fun which is a member of Odr_arm was changed. The result is,
1576 that an explicit typecast is needed for the fun pointer when
1577 using Odr_arm - as in:
1578 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1580 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1582 Implemented the new structured date and time definition as approved
1583 by the ZIG. Added schemaId element to the specificTag in Espec-1
1584 (also approved at the last ZIG). Thanks to RVDM.
1586 Added some Object identifiers (RVDM).
1588 Changed the Update Extended Service (RVDM).
1590 Added command "refid" to client which specifies referenceId for
1591 the following requests.
1593 Implemented extended service handling for server. See ztest.c
1594 for an example as well as backend.h. New handlers are registerd
1595 in the Init handler.
1597 * Changed interface for sort in server.
1599 Added new members to statserv_options_block. It allows a server
1600 to read options from another source than just the command line. Thanks
1601 to Charles Woodfield.
1603 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1604 renamed to zboolean. Some C++ compilers complained about the name.
1606 Minor changes to gils.abs. Added index 's' (sort) on title
1607 and date/time-last-modified.
1609 --- 1.4pl2 1998/1/30
1611 Fixed bug in server library regarding inetd mode (-i). This bug
1612 was introduced by release 1.4.
1614 --- 1.4pl1 1998/1/29
1616 Added sort facility in client and backend server interface.
1618 Fixed problem with dependencies in Makefile(s).
1620 Fixed bugs for encoders/decoders of extended services and
1623 Implemented sub-tree feature for schemas. Sub-trees are
1624 referenced in *.abs-files. See explain.abs for an example
1625 of the use of this feature.
1627 Modified bib1.att; local attributes for ANY didn't include
1628 ANY itself (only affects use of the retrieval module).
1630 Fixed bug in plain SGML reader in function data1_read_node:
1631 tags with prefix "var" was incorrectly interpreted as variants.
1633 Added feature "sub-schemas" to enable references to - and definitions
1634 of - group of elements.
1636 * Removed member parent from type data1_element (in data1.h).
1638 Implemented function odr_nullval() that returns the value of
1641 * Removed member num_children from data1_node (in data1.h).
1643 Made NT service interface part of the server library. The
1644 function statserv_main uses the NT service when required and
1645 calls the statserv_start / statserv_close routines.
1647 Routine zget_SearchRequest and zget_PresentRequest fills
1648 resultSetName/Id member with "default" instead of "Default".
1650 Fixed memory leak in server. Request queue member wasn't freed.
1652 Fixed nmem_exit so that memory is freed.
1656 Revised the CCL parser utility to be thread safe.
1658 Added function, oid_ent_to_oid, to replace the function
1659 oid_getoidbyent, which is not thread safe.
1661 * Added nmem_init and nmem_exit to initialize and release
1662 NMEM resources. Function nmem_init should be called once in the
1663 initial thread before NMEM/ODR is used. statserv.c and client.c
1664 have been changed accordingly. The change was necessary to make
1665 NMEM thread safe. The NMEM memory pool is shared amongst threads
1666 in a process. Unix-based applications will still work fine without
1669 Added NT Services interface for the the Z39.50 (statserv) Server.
1670 Refer to the ztest.c source on the usage.
1672 Windows 95/NT port using MSVC5.0. Project files are included in the
1675 * Defined new 'global' handle for the retrieval (data1) system. The
1676 new handled, data1_handle, describes the state of the data1 system.
1677 This handle is passed as first argument to virtually all
1678 data1 related routines. The functions data1_create and data1_destroy
1679 creates and destroys a data1 handle respectively.
1681 Added ODR encode stream member to all backend request structures
1682 init, search, scan etc. This stream should be used to allocate all
1683 memory used for the response when thread safe operation is needed.
1685 Changed the comstack utility, cs_addstr, to be thread safe. The
1686 returned hostname string returned by the function is now part the
1689 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1690 function. The cs_straddr takes a COMSTACK handle as argument, so this
1691 function must be used after cs_create and before bind/connect.
1692 This function is thread safe.
1694 Moved test server to 'ztest' directory - generic server code still
1695 in 'server' directory.
1697 Made prefix query (pquery.c) utility thread safe.
1699 Added new function modifier YAZ_EXPORT to 'export' public DLL
1700 functions when using windows (see include/yconfig.h).
1702 Added definitions to the OID database (util/oid.c) (RVDM).
1704 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1706 Added call to ccl_rpn_delete in client program.
1708 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1709 release of RPN structure.
1711 Added support for C++, headers uses extern "C" for public definitions.
1712 With input from RVDM.
1714 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1715 Thanks to Ronald van der Meer (RVDM).
1717 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1719 Added support for private extensions to the OID database
1720 (oid_setprivateoids()). Thanks to RVDM.
1722 Added optional, physical ANY (key replication)
1724 Fixed null-reference problem in GRS-1 output filter.
1726 Proximity operator added to Prefix Query Format (PQF).
1728 In test client command "base" accepts multiple databases.
1730 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1734 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1736 Smallish bug-fixes in the new encoders/decoders (explain).
1738 Bug fixed in DeleteRequest.
1740 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1742 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1744 Added SOIF syntax (using private OID for now) to retrieval module and client.
1746 Added Update extended service.
1748 Added SearchResult-1 additional info structure.
1750 Added optional CCL (ISO8777) interpreter as separate module. Available
1753 --- 1.2 1996/6/10 (1st anniversary release)
1755 Added Summary record syntax. Lightly tested.
1757 Added OPAC record syntax. Untested.
1759 Added ResourceReport service encoders/decoders. Untested.
1761 Fixed bug in z_Unit - wrong tagging on unitSystem.
1763 Fixed bug in the DiagRecs decoder.
1765 Added options for max PDU size and session timeout to frontend-server.
1767 Added documentation of query-language parsers and other supporting utilities.
1769 [frontend-server] Added Attribute set to the bend_scanrequest API.
1771 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1772 surrogate diagnostics were generated.
1774 [retrieval] Allow multiple local values for attribute.
1776 [retrieval] Allow multiple attributes per element in .abs files. index type.
1778 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1780 --- 1.1pl2 1996/4/10
1782 Minor changes, mostly specific to Zebra's requirements (retrieval)
1786 Repaired bug in frontend server when running multiple listening
1787 endpoints in dynamic mode.
1789 z_External() now won't break if a known, ASN.1 value comes encapsulated
1790 in an octet-string. The value will pass through unmodified in an Odr_oct.
1792 Added a bit of code to the demo client to decode & display
1793 ASN.1-structured records represented in the octet-aligned branch of
1794 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1796 Added z_ext_getentbyref() to the ASN module. Doc updated.
1798 * Completed the SCAN definition in the ASN module. This may break SCAN
1799 code based on older YAZ-versions at compile-time. The fix is easy -
1802 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1803 under the SCAN definition. Remember to initialize this, server-people.
1805 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1806 that this does not extend to ODR and ASN.
1808 Comstack allows insertion of established socket (primarily for
1809 inetd-operation of servers). Doc updated.
1811 Front-end server can now start from the inetd in TCP mode. Doc
1814 --- 1.0pl4 1996/1/24
1818 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1819 the rank and record number.
1821 Adjustments to the frontend server.
1823 Fixed diagnostic BER dumper. It ignored the file argument.
1827 Various changes to retrieval module.
1829 Changed the union discriminators of the protocol files from enums to
1830 ints paired with #defines.
1832 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1835 *Changed operator in the RPN structure to 'roperator', again to avoid a
1838 Fixed problems in Explain decoders/encoders.
1840 --- 1.0pl2 1995/12/6
1842 Memory bug in log module fixed.
1844 --- 1.0pl1 1995/12/5
1846 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1848 Bug in Explain DatabaseInfo module fixed.
1850 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1854 The shift to v1.0 signals that we now consider the *core* functionality
1855 of YAZ reasonably stable (the core being more or less equivalent to
1856 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1857 tested (Explain not at all - though that will happen soonish).
1859 Minor changes to code to support Windows port.
1861 Various minor changes after we're getting to use GRS-1 & co. more.
1863 Added Espec-1 format.
1865 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1866 of the protocol and it cannot be selected when encoding (maps into 'string'
1867 when decoding). Needed to talk to some servers.
1869 Demo client can request simple element set names.
1871 Added Diagnostic Format encoders/decoders.
1873 Added simple Close handling to frontend server (no hooks for resource
1874 reporting yet), and demonstration client.
1876 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1878 --- 1.0b3 1995/08/24
1880 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1881 handled incorrectly when records were requested in the searchResponse. This
1882 will only affect you if you use the frontend-server.
1884 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1885 Test-client will ask for and print GRS1. Ztest will return dummy records
1888 Added Explain encoders/decoders to the service-level API. Untested.
1890 Added Extended Services: Item Order encoders and decoders to the Service-
1891 level API. Untested. We could use a recent copy of the pertinent bits
1892 of the ILL protocol to add those bits.
1894 Added diagnostic format 1 encoders/decoders to the service-level API.
1897 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1898 odr_cons.c, which causes a more correct output.
1900 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1901 was always set to 0 when no records were requested in the searchRequest.
1903 * Added better external-handling. This shouldn't harm old code that
1904 *encodes* externals. It can break code that looks for a
1905 'single-ASN1-type' representation, since those types that are known
1906 are now decoded immediately. Look at the SUTRS sample code in
1907 seshigh.c and client.c. Documentation updated.
1909 Handling of structured records in bend_fetchresponse. Length -1 marks
1910 structured record, type is deduced from format field.
1912 --- 1.0b2 1995/06/27
1913 Fairly quick maintenance release to add SUTRS support.
1915 Fixed handling of SUTRS records in the demonstration client.
1917 * Added format field to the bend_fetchrequest and bend_fetchresponce
1918 structures of the backend API (frontend server). When the record is
1919 returned, the value of the format field is mapped to an OID. The
1920 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1921 of the record. The special value VAL_NONE in the bend_request means
1922 that no specific format was requested by the client. Documentation
1923 updated accordingly. Test server (ztest) will return a fixed dummy
1924 SUTRS record if your client requests SUTRS.
1926 Documentation updated accordingly.
1928 You can now set external libraries and RANLIB support in the top-level
1932 First public release.
