1 Implemented ZOOM_record_error which returns error information for
2 record (surrogate diagnostic).
6 Updates for SRU Update by Ko van der Sloot:
7 1. Changed name from "operation" to "action"
8 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
9 versions in the code, marked as 'backward compatible'.
10 3. Added diagnostics for SRU Update.
12 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
14 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
16 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
18 For GFS, fixed problem with SRU diagnostic 'First record position out of
19 range' being issued for 0 hits.
21 zoomtst10 part of Windows Build.
25 Implemented yaz_filepath_comp which splits a path into file path
26 components (required by Zebra 2.0.3+).
28 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
29 BSD inspired license until now so this should not have any real impact on
30 anybody. See http://www.opensource.org/licenses/bsd-license.php
32 Fixed bug #687: Missing log lines.
34 Fixed bug #678: CQL to PQF translation does not preserve double-quote
37 Fixed bug #689: SRU diagnostics to be added.
39 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
40 whether a connection is idle (no more work do do).
44 Change type of optval from long to int for invocation of setsockopt with
45 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
47 Added support for specifying the max log file size for the Generic
48 Frontend Server. The size is given with option -r.
52 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
56 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
59 Fixed bug in Generic Frontend Server that could cause a server to stop
60 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
62 For the generic frontend server, the maximum record size is used as maximum
63 size of incoming packages (SRU + Z39.50). The value until was previously
64 only used in Z39.50 Init negotiation and, later, in a session controlled
65 sizes of records returned. This is controlled using -k option. It can be
66 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
70 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
73 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
75 New option for yaz-marcdump -lpos=value which allows setting a portion
76 of MARC header to a certain value.
78 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
80 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
81 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
85 Fixed problem with SRU mode type (soap, get, post) for yaz-client
88 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
92 Fixed MARC ISO2709 encoding routines to deal with character set
95 Minor changes to GFS logging. Database included in search request log
98 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
99 cached/multiple records.
101 Shared libraries are built by default on Unix+configure.
103 Changed cql2pqf transformation to use a different evaluation order. The
104 new order is: always, relation, structure, position, truncation, index
105 and relationModifier. Old order was: always, relation, relationModifier,
106 structure, index, position, truncation. Note that the the latter ones
107 override former ones for identical attributes.. The new scheme means that
108 it is possible to override any existing attribute with a relationModifier.
109 And also that it is possible to override everything for the index rule
110 (except the ones listed in relationModifier). No order is perfect but this
111 one, we believe, covers more real cases.. The "always" should have been
112 called "default", since the attributes there can be overridden with all
115 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
116 compilation phase, but also for yaz-config --cflags output. This allows
117 us to have public headers with Libxml2 stuff in them . It should also,
118 eventually, make Libxml2 checks redundant in packages using YAZ, such
121 --- 2.1.22 2006/06/15
123 Changed SRU update structure bend_update_rr so that SRU diagnostics are
124 stored in uri, message and details.. Previously diagnostics were stored
125 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
126 compatibility.. but he's probably the only one affected, so.
128 Added support for CCL, compiled on the client side, in ZOOM-C. This
129 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
130 input; the resulting query objects can be used for for searching with
131 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
133 YAZ' configure searches for OpenSSL by default.
135 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
136 SL_CTX_use_certificate_file. See
137 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
138 for more info. Thanks to Ko van der Sloot.
140 --- 2.1.20 2006/06/02
142 Bug #600: SRU GET, POST support for yaz-client. Introduced
143 command 'sru' which selects method SOAP/GET/POST.
145 Allow missingValueAction to be specified for the sortspec string -
146 function yaz_sort_spec. By default, the missing value action is null.
147 Use ! to specify "abort". Use = followed by stringvalue to specify default
150 Ensured that Present-handler (if defined) is called in GFS before any call to
151 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
152 searchRetrieve requests.
154 Documentation for YAZ is now based on the Docbook XML/XSLT using
155 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
156 is no longer depending on jade/openjade or docbook-to-man scripts.
157 PDF is no longer part of the distribution - but can optionally be
158 made using DSSSL/jadetex or FOP.
160 Added retrieval handling support in Generic Frontend Server to support
161 conversion between MARC/XML as well as XSLTtransforms. See
162 etc/yazgfs.xml for an example.
164 Added Authentication support to Generic Frontend Server in SRU
165 mode. Authentication using HTTP Basic is supported, as is the use
166 of 'x-username' and 'x-password' parameters in the request itself.
168 Added support for a new character set MARC8s identical to MARC8 except
169 that it converts combined characters to single Unicode characters in the
170 Latin-1 range (when possible).
172 --- 2.1.18 2006/04/24
174 ASN.1 compiler 0.4: generates brief Doxygen file header for
175 generated .h/.c files.
177 Utility yaz_iconv now supports conversion to MARC-8.
179 New facilities for the MARC module. The reading - and writing of
180 content are separate methods for the yaz_marc_t handle. The following
181 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
182 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
183 format). Write functions have prefix yaz_marc_write_.. The existing
184 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
185 available. Removed support for OAI-MARC and simplexml (not the
186 simplexml from PHP5).
188 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
189 to be returned for this connection.
191 --- 2.1.16 2006/03/31
193 Allow multiple languages and charsets to be specified with
194 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
195 negcharset iso-8859-1,utf-8
197 Translation of proximity nodes from CQL into PQF now works.
199 Moved to automake 1.8, 1.9.
201 Added function yaz_log_set_handler which allows a log handler to be
202 installed. This handler will be called for all log messages. Output
203 to file is also produced; but that can be disabled by passing NULL
204 fname to yaz_log_init_file.
206 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
208 For SRW (including GFS), accept application/soap+xml as content-type
211 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
212 produces NO stylesheet reference even if a default stylesheet is specified
215 --- 2.1.14 2006/03/14
217 Updated Windows package to include yazd.dll + yazd.lib for the
218 Development component.
220 If the environment variable YAZ_LOG is set, then it is used as a
221 string indicating the default level of logging to use if not
222 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
223 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
224 used as before. So, for example, to omit warnings from YAZ logging,
227 cql_transform() now map structure and other attributes before indexes,
228 so that index-specific structures and other attributes can override
229 defaults. So now a combination of mapping specifications such as:
231 index.dc.date = 1=date-modified 4=5
232 does the right thing.
234 cql_transform() now also respects the "always" mapping specification,
235 which establishes an initial set of attributes to be used for all
236 terms except where overridden by more specific attributes associated
237 with the index, relation or modifier.
239 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
240 which mode to use; one of "post", "get" or "soap" (SRW, default).
242 Fixes for yaz_iconv routines: changed trie-based character set conversions
243 to use only non-negative values for bit fields due to Sun's C compiler not
244 supporting negative values.
246 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
247 sequences where not read correctly. Fix by Rustam Usmanov.
249 Updated win/makefile to use options, settings which makes things
250 compile with VS C 2005.
252 --- 2.1.12 2006/02/01
254 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
256 In ZOOM socket code, use select instead of poll on MacOSX.
258 ZOOM-C now support client-side compilation of CQL into RPN that is
259 sent to the server, enabling CQL to be used against all Z39.50
260 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
261 ZOOM_query object, and submit it using ZOOM_connection_search().
262 The CQL-to-RPN translation uses a configuration file, the name of
263 which must be specified in the Connection's "cqlfile" option.
265 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
266 function, which takes as its start-term parameter a ZOOM_query object
267 (which may have had either CQL or RPN set into it).
270 --- 2.1.10 2005/11/29
272 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
273 GFS to support this as well. Backend handler, bend_srw_update, does the
274 update work. Code contributed by Ko van der Sloot.
276 Allow retrieval of Search Result-1 information in ZOOM by the use of
277 options that are attached to a result set. ZOOM documentation updated
280 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
281 UTF-8 conversion. Patch by Raj Patel.
283 Added option -m to GFS to control formatting of timestamps in log file.
285 Added 'exit' as synonym for 'quit' in yaz-client
287 Added support for specifying SRW resultSetId + resultSetIdleTime in a
288 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
289 for the new members. Patch by Ko van der Sloot.
291 Added support for SRU POST. It is supported for content-type
292 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
294 Do not build the separate Multi-threaded (MT) library libyazthread.la.
295 Instead make the library libyaz.la multi-threaded. Threading as a whole
296 can still be disabled by configure option --disable-threads. Previosly,
297 with older GLIBCs there were problems with MT libs under Apache. This
298 has now been fixed a long time ago.
300 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
303 CQL module modified to be case insensitive for relations/indexes/operations.
305 Fixed bug in CQL transform code: incorrect value relationModifieder
308 Added 'show all' command for yaz-client which retrieves all results
311 Added new yaz-client, xmles, which takes a (private) OID and
312 a document to be sent as an extended service request.
314 Describe new yaz-client commands wait_response and set_auto_wait.
316 Increase TCP/IP listener backlog from 3 (which I am guessing was
317 copied from the SunOS manual entry way back when) so SOMAXCONN, so
318 that the socket will queue as many incoming connections as it's able
319 to handle ongoing connections. In other words, it will never now
320 refuse a connection that it would be able to handle merely because
321 it's not got around to accepting() enough of the pending connections
322 yet. This is the behaviour anyway under Linux, where the listen()
323 argument is ignored; but not under BSD and on systems such as
324 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
325 YAZ-based servers should now be uniform across operating systems in
328 yaz-marcdump uses 64-bit file access on some systems. This is enabled
329 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
330 This allows yaz-marcdump to read large MARC batches (>2 GB).
332 Modified all YAZ source files - except the source which is auto-generated
333 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
336 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
337 corresponding to the existing *_setl() function. These allow option
338 values containing arbitrary valuues.
340 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
341 ZOOM_resultset_sort() in new applications. Its behaviour is identical
342 except that it returns an indicator of whether or not the sort
343 criterion was accepted (0 for OK, -1 for invalid).
347 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
348 MARC output rather than returning "new" buffer.
350 yaz-client warns about unknown init options.
352 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
356 Added support for SRW sort in Generic Frontend Server. Patch
357 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
358 sortKeys - or NULL if none is provided.
360 Fixed bug #307: It was impossible to specify indefinite/no timeout
361 for ZOOM_event. Special timeout value -1 now means indefinite timeout
364 Added support for multiple languages and charsets to be specified in
365 ZOOM. Each charset/language is separated by a blank. If negotiation is
366 in effect in init-response, Option
367 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
368 Code based on patch by Vasiliy Osadchuk.
370 Fixed bug #306: infinite recursion that occurred when calling
371 yaz_log_level_init as the first call (before other log level or
374 Fixed bug in scan handling in front end server: if preferred-Position-In-
375 Response was non-present, a NULL pointer referece was performed.
379 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
380 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
381 now defined for all those error codes. So instead of putting 109 in
382 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
383 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
385 Modified the yaz-marcdump utility to skip garbage bytes between MARC
388 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
390 Program yaz-client now exits and produces an error message if multiple
391 Z39.50 servers are specified on the command line (none or one allowed
394 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
399 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
401 Fixed bug #272: Preserve spacing for CCL terms.
405 Added support for virtual hosts and multiple backend servers for
406 the YAZ frontend server. The configution is XML based and
407 support specificition of CQL to RPN mappings and explain information.
408 See section "Virtual Hosts" in the YAZ manual.
410 Extended OPAC display utility. OPAC display utility renders
411 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
412 to supplement yaz_marc_decode_wrbuf.
414 Fixed a bug in MARC decoder that could caused it to crash for some
415 invalid MARC records. More diagnostics and warnings where added in
416 XML output (warnings, etc are stored in comments).
418 --- 2.0.34 2005/02/08
420 Fixes for UNIX domain sockets. Bug #261.
422 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
424 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
425 Added yaz_marc_subfield_str which defines subfield lead string which is
426 used in YAZ_MARC_LINE format. Default string is blank+$. Added
427 yaz_marc_endline_str which defines end of fields string used in
428 YAZ_MARC_LINE format. Default string is newline.
430 Experimental support for MarcXChange. This format can be produced
431 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
432 http://www.bs.dk/standards/MarcXchange.xsd
434 Added yaz-client commands scansize that sets maximum number of
435 entries to be returned by scan.
437 --- 2.0.32 2005/01/11
439 Added support for SRW scan in yaz-client and Generic Frontend Server.
441 * Added whereInList member to SRW Scan Term.
443 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
445 Fixed NMEM system to return aligned blocks on the smallest boundaries
446 that are suitably aligned for all possible types on the particular
447 architecture YAZ is being built for.
449 --- 2.0.30 2005/01/04
451 Fixed numerious warnings that was issued with newer versions of GCC.
453 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
454 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
457 Make YAZ Generic Frontend Server slightly faster.
459 Enhance (and reduce) logging for Generic Frontend Server.
461 Revert YAZ log system so that it flushes every write operation
462 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
464 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
465 instead of LOG_, due to name clash with syslog(3). LOG_ are still
466 present. New applications should define YAZ_USE_NEW_LOG=1 - this
467 will effectively disable old definitions.
469 --- 2.0.28 2004/11/09
471 Added yaz_log_time_format which specifies log format using
474 Added yaz_log_module_level which returns mask for a module. Value
475 is non-zero mask a if module is enabled; zero if disabled.
477 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
478 in include/yaz/cql.h.
480 Fixed bug #176: Dont throw diagnostics on empty SRU args.
482 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
484 Fixed bug #172: RPM builds does not enable SSL.
486 Doxyfile.in part of dist. Doxyfile generated by configure.
488 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
489 are given and the corresponding component does not exist.
491 Extend CCL documentation in YAZ reference. Describe r=r.
493 --- 2.0.26 2004/10/01
495 Fixed MARC->MARCXML conversion to properly deal with
496 fields, subfields, indicators having non-ASCII characters.
498 Fixed MARC->MARCXML conversion so that ASCII control characters
499 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
502 Added YAZ GFS support for conversion from Z39.50 surrogate
503 diagnostics to SRW surrogate diagnostics.
505 Bug fix: YAZ GFS did not return schema in explainResponse.
507 --- 2.0.25 2004/09/30
509 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
510 now converts recordSchema to elementSetName as well as schema URI.
512 Fixed bug in COMSTACK that prevented HTTP request packages from being
515 --- 2.0.24 2004/09/29
517 Added CCL facility r=r "range" which is similar to r=o "ordered" but
518 does not require white-space before and after the dash in a range, e.g.
519 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
522 Fixed a few AC_TRY_LINK configure tests that did not operate properly
523 due to new GCC removing "redundant" code.
525 Added yaz-client commands scanpos and scanstep that sets preferred
526 position and step-size for scan.
528 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
530 Added CCL utility ccl_qual_buf which parses one or more CCL
531 spec lines in a buffer.
533 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
534 of name and value - ignoring empty lines and comments.
536 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
538 Added odr_get_element_path which returns current element path for an
539 ODR handle. This utility is useful in error handling or user-defined
542 Added ODR_PRINT utility odr_set_stream which is is a more generic
543 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
544 to a write function and pointer to close function. The close function - if
545 non-NULL - will be called during odr_destroy.
547 Fixed bug in CCL parser where truncation char was not removed from
548 right side when truncation=both was in effect.
550 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
553 --- 2.0.23 2004/08/11
555 Fix buffer overrun in CQL parser when dealing with proximity (%).
557 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
558 to UTF-8/UCS conversion is now only based on codetables.xml.
560 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
562 --- 2.0.22 2004/08/06
564 Add support for more "commit changes" in ZOOM (uses Extended Services).
566 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
569 Yet another small fix for configure of SSL.
571 --- 2.0.21 2004/05/14
573 Fix SSL libs for configure when --with-openssl=DIR is given.
575 --- 2.0.20 2004/05/10
577 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
579 SSL comstack now uses yaz.pem certificate file on server side
580 by default. Certificate filename can be configured by calling
581 comstack function cs_set_ssl_certificate_file before cs_bind is used.
583 Fix bug regarding multiple calls to ZOOM_connection_connect.
585 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
587 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
588 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
590 ZOOM now allows inspection of X509 peer certificate for verification.
591 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
593 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
594 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
595 as "modular" but it simplifies things.
597 Added cs_get_peer_certificate to that returns peer X509 PEM.
599 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
600 NULL if SSL is unavailable.
602 Documentation about MARC decoding tools.
604 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
606 --- 2.0.19 2004/03/30
608 Rename CHANGELOG to NEWS to follow GNU style packing.
610 Fix bug with missing initialization of member in init_diagnostics.
611 This bug affects threaded version of GFS server.
613 --- 2.0.18 2004/03/20
615 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
618 Ensure zlib.dll is packed with Windows install.
620 --- 2.0.17 2004/03/17
622 Fix encoding of xsd:string to use text instead of CDATA.
624 Fix endless loop in CQL parser with unbalanced ".
626 Use a more compact way to store MARC-8 conversion tables.
628 --- 2.0.16 2004/03/16 Debian only
630 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
633 Update CQL parser to use new CQL 1.1 modifiers for booleans and
638 --- 2.0.15 2004/03/01
640 Another fix for decoding of XML packed records.
642 --- 2.0.14 2004/02/25
644 Fixes for Chunked encoding. White space not ignored after length spec.
646 Update NS and use default NS for SRW diagnostic elements.
648 --- 2.0.13 2004/02/23
650 Implement ZOOM_resultset_cache_reset which resets record cache.
652 Implement ZOOM_resultset_sort which sorts a result set.
654 Implement chunked HTTP transfer.
656 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
658 --- 2.0.12 2004/02/16
660 Added member 'schema' to bend_explain_rr structure so that backend
661 can specify explain record identifier. Defaults to Zeerex 2.0.
663 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
665 --- 2.0.11 2004/02/16
667 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
670 Added init command for yaz-client which sends "extra" init request.
672 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
673 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
675 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
677 Make ZOOM error code for "invalid query".
679 Fixed compilation for SSL which wasn't properly enabled for all platforms.
681 --- 2.0.10 2004/02/05
683 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
686 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
688 Added option -p <file> to make Generic Frontend Server to write PID file.
690 Added option -D to put Generic Frontend Server in background on its own.
692 Make ZOOM C recognize option "password". If unset, "pass" is used
693 (for backwards compatibility).
695 Fixed a bug in Generic Frontend Server that could make it crash if a
696 client sets characterSetNegotation bit, but didn't pass negotiation stuff
699 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
700 Must be issued before open, in order to be in effect.
702 --- 2.0.9-6 2004/01/12 Debian/Windows
704 Make the SRU server more picky WRT unknown params, etc.
706 Bug fix: ZOOM scan response didn't return displayTerm - when present.
708 New YAZ client command, options, that sets Z39.50 options.
710 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
711 options from a string of tokens (one token for each option bit).
713 Update SRW diagnostic code messages.
715 --- 2.0.9-5 2004/01/07 Debian/Windows
717 Handle user defined stylesheet for SRW/SRU.
719 --- 2.0.9-4 2004/01/06 Debian/Windows
721 Fix bug in decoding of Content-Length.
723 --- 2.0.9-3 2004/01/06 Debian/Windows
725 Fix a bug with decoding of XML packed records.
727 --- 2.0.9-2 2004/01/05 Debian only
729 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
731 Fix bug in SRW/SRU diagnostics decoding.
735 Fixed bug in Generic Frontend Server which could drop records exceeding
736 preferred message size. Reported and fixed by Irina Dijour.
738 Fixed calculation of package size for structured records in Generic
739 Frontend Server. Reported and fixed by Irina Dijour.
741 Fixed namespace for SRW/SRU diagnostics.
743 Fixed SEGV in yaz-client that occured for HTTP connection errors.
747 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
748 this version is incompatible with version 1.0 and older YAZ SRW/SRU
751 CQL changes to reflect recent changes to the specification:
752 * Documentation talks about context sets instead of index sets.
753 * Documentation talks about indexes instead of qualifiers.
754 * The CQL-to-PQF transformer's configuration file now uses
755 "index.set.name = <attributes>" instead of the old form
756 "qualifier.set.name = <attributes>". (Both forms are still
757 understood but the latter is deprecated.)
758 * CQL terms with no explicit index specified are now interpreted as
759 cql.serverChoice instead of srw.serverChoice (which of course
760 behaves exactly the same.)
764 MARC conversion can now generate ISO2709 output in another
765 character set. yaz-marcdump uses this facility if you invoke it
768 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
769 functions from there can be used from C++.
773 Frontend server now transfers memory from decoded packages to stream
776 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
777 references to show up.
779 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
780 the ZOOM Abstract API. The older names for the same options are still
781 also supported for the benefit of old applications.
783 ZOOM-C supports "implementationId" and "implementationVersion" options
784 to go along with "implementationName". These allow the user code to
785 specify identification strings to be sent to servers.
786 Add OID for the new ExtLite attribute set.
788 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
789 as requested/supplid by Ere Maijala <ere@atp.fi>
791 For generic frontend server, reverse the order of
792 "toolkit-supplied / application-supplied" strings sent as implementationId,
793 Name and Version. Also, remove the spaces around the slash. This brings
794 the GFS in line with the behaviour of ZOOM-C on the client side.
796 Add function ZOOM_scanset_display_term.
798 yaz-client shows scan displayTerm if present.
800 Utility yaz-iconv is now installed by default along with the man page
803 Extend configure check for OpenSSL to use pkg-config where available (such
806 Incorporate patch by Morten Bogeskov which allows a Unix file socket
807 server to specify uid/gid/mask for socket using the format
808 unix:[user=uid,][group=gid,][umask=mask,]file=path
809 If file= is omitted the existing format is assumed, e.g.
811 in which case the mask is 0666 (rw for everybody).
813 Major restructure of YAZ source. All source in libyaz is in src directory.
814 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
815 util (utility programs such as ASN.1 compiler, yaz-marcdump).
817 Added man page for utility yaz-marcdump (used to be called marcdump).
818 yaz-marcdump is installed by 'make install'.
820 Fixed a memory leak in Generic Frontend Server that occurred when decoding
821 of incoming package failed.
823 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
825 Change prototype of odr_perror: add const to message string.
827 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
829 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
830 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
831 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
832 DNS lookup. There should not be any compatibility problems with this
833 assuming that blocking=1 or 0 is used.
835 Fix bad reference in UNIX comstack in function cs_addrstr.
837 Fix for compilation on AIX.
839 The generic front-end server (server/seshigh.c) now supports returning
840 Init diagnostics to the client in User-information-field, in
841 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
846 Allow any CQL relation (not just all,any,exact,scr).
848 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
849 that features the same UI.
851 Implemented command update0 in YAZ client which is equivalent to
852 update but uses old of Ext Update ASN.1.
854 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
855 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
856 Previously no OID was used for this info.
858 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
859 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
860 returns 'malformed search term' otherwise.
862 SortResponse member resultCount now set to NULL in sort handler of
865 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
868 Add three new utility functions for translating OIDs between various
869 formats -- symbolic name such as "Usmarc", minus-1-terminated int
870 arrays and dotted strings such as "1.2.840.10003.9.5.1":
871 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
872 char *oid_to_dotstring(const int *oid, char *oidbuf);
873 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
875 Reverted modifications for ES Update definition for z_IU0Update
876 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
877 is back to YAZ 2.0.2.
879 String value attributes for CCL parser.
881 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
882 which their FirstSearch server returns in Init responses, sometimes
883 carrying useful diagnostic information when Init fails. This has the
884 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
885 "z39.50/oclcui.asn", where its definition is somewhat different from
886 what OCLC document on their web-site, as required to interoperate with
889 Support for anonymous authentication in yaz-client. Use the command
892 * Fix the OID of the Index Data-local "admin" Extended Service from
893 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
894 the 1000, which indicates a locally-defined OID, was a mistake.
898 Fix CCL directive @case handling so that it affects string match for
899 both CCL keywords and qualifiers.
901 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
902 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
903 Decoder has been updated with ASN.1 changes as listed in
904 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
905 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
906 z_IUUpdate, remains unchanged.
908 ZOOM_record_get may now return a record in a specific character set.
909 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
910 "from" is the character set of record as returned by target. "to" is
911 the character set to be returned. If omitted, "to" is UTF-8.
913 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
915 New ODR utility, odr_getelement, which returns name of element for
916 which encoding/decoding failed.
918 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
919 in cases where a required element was omitted.
921 Bug fix: some MARC8 sequences were not converted.
923 New ZOOM option "step" which specifies number of records to be
924 retrieved in one chunk. Used in conjunction with "start" and "count".
926 SRW support for yaz-client. Use scheme http: to use it, e.g.
929 yaz-client no longer does (un)intelligent character set conversions
930 by default. Can be enabled with charset and marc_charset commands.
932 xmalloc trace fix for 64-bit systems such as DEC alpha.
934 Solaris 2.6 compile fix.
936 New function, cql_strerror() translates SRW error codes, as returned
937 by cql_transform_error(), into human-readable English strings. Used
938 in yaz-client diagnostics when appropriate.
940 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
941 converts it into a type-1 query which is sent to the server. This
942 makes CQL available for use with all Z-servers, as opposed to the tiny
943 minority that can handle CQL queries themselves.
947 New Debian package layout similar to the Redhat Package layout.
949 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
950 and search result respectively.
954 Redhat package is now several packages: libyaz (runtime libraries),
955 libyaz-devel (development and documentation, and yaz (utility programs).
956 Package spec file by Morten Bøgeskov.
958 New member 'schema' in struct bend_fetch_rr which the name of requested
959 schema (SRW/SRU) for record (or NULL if none was given). The fetch
960 handler MAY set this to reflect the schema of the returned record.
962 New member 'display_term' in struct scan_entry. GFS now sets member entries
963 and allocates scan entries to be filled by user scan handler. In previous
964 version, entries member was allocated by the scan handler. That still works,
965 but the GFS will ignore member display_term - assuming it was NOT set by
966 the handler. The fact that the GFS now allocates the entries both allows
967 for new members and makes a scan handler easier to write.
969 Fix CQL lex buffer overflow.
971 SRW/SRU recordPacking. For SRW default recordPacking is string. For
972 SRU default recordPacking is string.
974 SRU protocol support for frontend server.
976 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
978 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
980 Added scan for the ZOOM shell (zoomsh).
984 * String Identifers for Schemas (Amendment 5).
985 http://lcweb.loc.gov/z3950/agency/amend/am5.html
986 Old definition for schema
987 Odr_oid *schema; /* OPT */
992 Z_InternationalString *uri;
993 #define Z_Schema_oid 1
994 #define Z_Schema_uri 2
997 * resultCount parameter to Sort Response (Amendment 1).
998 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1000 Support for SRW 1.0 over HTTP. This is an optional feature and
1001 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1004 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1005 on the same port. SRW SearchRetrieveRequests are mapped
1006 to bend_init,bend_search,bend_fetch,bend_close.
1008 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1010 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1011 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1013 ZOOM connections are SRW based if schem http is used for hostname
1014 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1015 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1017 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1018 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1019 distance=n, order=true/false, relation=le, prox unit=word. If
1020 n is omitted, distance 1 is used.
1022 Fixed problem with C compiler include path in wrong order.
1024 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1025 on Solaris. Patch from Ko van der Sloot.
1027 New MARC decode API. All new functions operate on a yaz_marc_t
1028 handle. The most important new functions are: yaz_marc_create,
1029 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1030 decode and destroy respectively. Decoder can produce formats
1031 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1032 include/yaz/marcdisp.h.
1034 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1035 to UTF-8, UCS-32, wchar_t or Latin-1.
1037 * Prototypes for yaz_iconv_-functions moved to separate header
1038 include/yaz/yaz-iconv.h.
1040 Make a few private functions 'static' in unix.c. This prevents
1041 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1043 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1044 are set when Init Response is received.
1046 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1047 but returns diagnostic set as well.
1049 New function yaz_strerror which is a portable wrapper for
1050 strerror/strerror_r/GetLastMessage.
1052 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1053 is returned for MARC. If type is "oai", then OAI MARC is returned.
1055 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1058 --- 1.9.2 2002/11/26
1060 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1062 Fix bad race conditions on SIGTERM and terminate gracefully in
1065 Move retrieval (data1) module to Zebra since nobody seems to be
1068 Add GRS-1 render for ZOOM using same format as yaz-client.
1070 --- 1.9.1 2002/10/05
1072 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1074 Fix broken ESpec handling in data1 module.
1076 SGML reader parses comments and makes them part of the data1 tree.
1078 Added several type casts so that YAZ compiles as C++ code.
1080 ZOOM didn't handle PDU encoding failures properly.
1082 Added more Bib-1 diagnostics (approved extensions).
1084 GNU configure: better check for iconv.
1086 More portable use of accept, getpeername. Check for socklen_t. Use
1087 int/size_t if socklen_t is not defined.
1091 PQF parser rejects bad queries - including those with extra
1092 characters in them. PQF parser used to silently ignore that.
1093 Cleaner API for PQF added, which allows you to get detailed
1094 error information for bad queries (see yaz/pquery.h).
1096 Fixed bug in ZOOM_record_get for type "database".
1098 Implemented mini iconv library supporting conversions between
1099 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1101 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1103 --- 1.8.9 2002/08/20
1105 Fixed ZOOM C record cache so that preferredRecordSyntax and
1106 elementSetName is used to check for already fetched records.
1108 --- 1.8.8 2002/08/02
1110 Added three members in bend_initrequest structure to facilitate
1111 character set negotiation.
1113 Fixed a bug in frontend server that could cause indefinite
1114 loops under rare conditions.
1116 Revised character set utilities (charneg.h) so that encoding
1117 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1119 For PQF, directive @term <type> sets term type for Scan/Search.
1120 Here <type> is general, string, numeric, null. The term type
1121 is inherited - just like @attr.
1123 New call odr_set_charset that sets character set conversion for
1124 international-strings on a ODR stream. Prototype is:
1125 int odr_set_charset(ODR o, const char *to, const char *from);
1126 The InternationalString is still represented as C string in YAZ
1127 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1128 won't). On the protocol level, you can use any encoding.
1130 Support for UNIX sockets in ZOOM.
1132 Solaris recv sometimes returns errno == ENOENT. It is treated as
1133 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1135 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1136 both client and server. Code by Morten Bøgeskov.
1138 --- 1.8.7 2002/05/22
1140 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1141 that they can be used directly from Visual Basic. You must recompile
1142 your windows APP if you're using ZOOM.
1144 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1145 Commands "lang" and "charset" sets language and character set respectively.
1146 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1147 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1149 Attributes from multiple CCL fields may be OR'ed rather than merged
1150 using directive "@field or". Fields are still merged by default -
1151 equivalent to "@field merge".
1153 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1156 Fixed bug in zget for parameter ExtendedServicesResponse.
1160 --- 1.8.6 2002/03/25
1162 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1164 Client displays USR.1:SearchResult-1 (hits per term).
1166 Additional Search Info for search in Generic Frontend Server.
1168 Fixed CCL parsing of "field=s".
1170 WIN32 installer - using the excellent NSIS software from nullsoft.
1172 Fixed CCL parsing of "field = - <number>".
1174 Added function yaz_marc_decode that decodes MARC for line mode
1175 display or XML (similar to that used by JZKit).
1177 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1178 Z39.50. But ISO/ILL was, however.
1180 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1181 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1183 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1184 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1186 --- 1.8.5 2002/02/03
1188 New YAZ client features: Command completion and new commands:
1189 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1190 Code provided by Jacob Poulsen.
1192 New call oid_trav, that visits all registered OIDs via callback.
1194 Function ZOOM_record_get now returns const char pointer rather than
1195 void pointer. It saves a lot of type casts.
1197 For YAZ client, command "auth" now allows you to set authentication
1198 in IdPass style. It is enabled when three tokens are given - order
1199 is user, group and password.
1201 Fix memory leaks in MARC record handling for ZOOM.
1203 New option for YAZ client, -k <kilobytes> that sets
1204 maximum record size. Similar to -k option for generic frontend
1205 server and yaz-ztest.
1207 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1209 Prefix query parser reports "fail" when bad attribute set is given.
1211 Fix in MARC decoder. Proximity logging. Fix for attribute set
1212 in scan handler for server. Patches by Shigeru Ishida.
1214 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1217 Configure option --with-openssl=<dir> now works when a directory is
1218 specified. Patch provided by Morten Bøgeskov.
1220 New option for YAZ client, -u <auth>, that sets authentication.
1222 ZOOM fix: error information was sometimes "missing", since error
1223 was cleared/reset too when it shouldn't.
1225 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1227 --- 1.8.4 2002/01/04
1229 Scan for ZOOM API. New object ZOOM_scanset. New functions
1230 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1231 ZOOM_scanset_destroy.
1233 New ZOOM function, ZOOM_connection_last_event, that returns type
1234 of last event (such as "receive data", "send data", "apdu received",
1237 New ZOOM option, schema, that specifies schema for retrieval.
1239 New CCL feature. Qualifiers can be aliases for one or more
1240 other qualifiers (if more than one is given, OR is used).
1242 ZOOM uses named result sets if target supports it.
1244 Two new YAZ client commands: . (dot, which sources a script of YAZ
1245 client commands), and ! (to execute shell command.). Implemented
1248 Working on Debian packages.
1250 --- 1.8.3 2001/11/19
1252 YAZ client enables named result sets only if target supports it.
1254 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1256 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1257 with key="host" to get same result.
1259 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1260 Function Z3950_resultset_record(s) returns references to records
1261 "owned" by resultset. To become owner use Z3950_record_clone.
1263 Function z_ext_record handles Extended Services. Thanks to
1266 --- 1.8.2 2001/11/12
1268 CCL Parser fix: ignore token comma when dealing with and-lists.
1270 Documentation updates for COMSTACK.
1272 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1273 Changed prototype Z3950_records. For some functions, int parameters
1274 were changed to size_t.
1276 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1279 New MARC decode/display function, marc_display_exl, which properly rejects
1280 non-ISO2709 records. YAZ client uses it.
1282 --- 1.8.1 2001/10/29
1284 Fix bug: local attribute set wasn't set correctly in PQF strings.
1288 * Old Z39.50 codecs no longer supported.
1290 Added ZOOM C binding. See http://zoom.z3950.org/
1292 Renamed states for COMSTACKs to avoid confusion with events.
1294 Implemented cs_look and proper cs_rcvconnect.
1296 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1298 Configure detects POSIX threads on OpenBSD.
1300 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1301 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1303 When error is returned from present handler, non-surrogate diagnostic
1304 is returned in present response (and fetch handler is no longer called).
1306 * Minor adjustments to pquery parser (PQF). Token characters may be
1307 escaped by using backslash (C-style).
1309 PQF parser allows string attribute values to be specified. For @attr,
1310 non-numeric characters after the equal-sign are treated as strings
1311 (e.g. @attr 9=title).
1313 CCL trunction character may be defined (@truncation in file)
1315 * function zget_ExtendedServicesRequest sets waitAction to
1316 waitIfPossible (was wait).
1318 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1321 CCL operator names may be set in field definition files (CCL_bibset).
1322 See ccl/bib1 for an example.
1324 Fixes in ASN.1 compiler for C++ compatibility.
1326 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1327 and "op_or" to avoid conflict with C++.
1329 Fixed problem with GNU readline detection on Redhat 7.0.
1331 Added step-size for Scan backend handler.
1333 Fixed bug that made the frontend server crash when no attribute
1334 set was specified for scan.
1336 Front-end server automatically switches to original working directory
1337 when installed as an NT service. Previously -w had to be specified to
1340 Added extended attributes for retrieval module (data1), so that data1
1341 records carry d1_readXML/SGML attributes. d1_read also supports
1342 null-data rules ( <tag/>)
1344 On UNIX when POSIX threads are available, a separate library libyazthread
1345 is created. Programmers should link with that library and the yaz library
1346 when using threads. The reason for the split was that some applications
1347 on Linux, such as Apache, doesn't work well when using shared objects that
1350 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1351 (or any frontend server) in SSL mode by specifying ssl: followed by
1352 address. Only tested on UNIX.
1354 Added feature for CCL module. Virtual structure s=al or s=ol generates
1355 and-list and or-list respectively instead of phrase search.
1359 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1360 log_mask_str. This was done to avoid name conflicts with other libraries
1361 (such as other PHP extensions).
1363 Added raw OID member for preferred record syntax (request_format_raw)
1364 and returned record syntax (output_format_raw) for backend fetch method.
1366 Config file yaz-config now accepts options so that it returns specific
1367 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1369 Shared library support for UNIX using GNU libtool.
1371 * Modified backend interface. Request/Response struct's replaced by
1372 one read/write C struct. For example bend_fetchrequest and
1373 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1374 Every handler - even search has to be registered in bend_init
1375 handler. This means that the YAZ library no longer refers to
1376 external functions and it makes it possible to make the whole
1377 thing a single DLL/SO.
1379 Added Segment handler for backend server.
1381 Added Zmbol/Zebra administrative functions to YAZ client.
1383 Threaded frontend server on UNIX (when POSIX Threads are available).
1384 Starting the server with option -T enables multi-threading.
1388 Added configure option --enable-comp/disable-comp to control use
1389 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1390 located in sub directory asn.
1392 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1393 in ${exec_prefix}/bin along with the other programs yaz-client and
1396 GNU automake used to maintain makefiles.
1398 Added several OID's.
1400 Changed retrieval module so that we can load records with no abstract
1401 syntax defined. Tagpaths in these records are fully composed of string
1404 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1408 On UNIX, the generated makefile now supports a proper 'make install'.
1409 The prefix can be set via GNU configure to set the install location
1410 (default is /usr/local).
1412 * YAZ programs client and ztest were renamed to yaz-client and
1413 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1414 locations, such as /usr/bin,/usr/local/bin,etc.
1416 * YAZ Header files were moved from include to include/yaz. YAZ Header
1417 files are referred to as include <yaz/log.h> rather than <log.h>.
1418 The YAZ include path (-I ..) is therefore the same as before. Programmers
1419 should update their #include statements or use -Ipath/include/yaz
1420 instead. The main motivation for doing this change is that YAZ header files
1421 can be installed in "standard" locations /usr/include,/usr/local/include
1422 without introducing conflicts, since ALL YAZ header files are stored
1423 in subdirectory yaz (under /usr/include for example).
1425 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1426 rather than project/workspace files. We switched because project files
1427 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1430 Changed name of logging function, logf, to yaz_log, to prevent name
1431 clash with some math-log functions. The YAZ header log.h defines logf
1432 to yaz_log (#define) so there should be no incompatibilities by this
1435 Added bend_start/bend_stop handlers for server. These handler are
1436 called on start/stop of server. For windows they are called whenever
1437 a service is started/stopped.
1439 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1440 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1441 in util/yc.tcl. The auto-generated C code structures are, in a few
1442 cases, incompatible with the old decoders. There are differences in the
1443 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1444 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1445 The preprocessor variable ASN_COMPILED is defined when the compiled
1446 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1447 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1448 wish to use the old encoders/decoders you can specify --disable-yc
1451 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1452 version so that it supports both new - and old version of DB Update
1454 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1455 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1456 change. The name parameter can be set to 0 in which no name is specified
1457 for the construction. The macros odr_implicit and odr_explicit sets name
1458 parameter to zero for the construction involved. New macros
1459 odr_implicit_tag and odr_explicit_tag are similar to the others,
1460 except that a name parameter is added. For programmers' that don't use
1461 ODR they probably only need to change the call to z_APDU and z_External.
1463 Added access control facility by interfacing the TCP wrapper library.
1464 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1465 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1466 name of the daemon and enables the access control as specified in
1467 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1469 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1470 den Dool <H.M.vdnDool@kub.nl>.
1472 Added reference ID parameter to most functions in server API - refer
1473 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1475 Changed name of ccl library to libccl.a (was ccl.a).
1477 Fixed bug in decoder for Explain (Category TargetInfo).
1479 Added support for GNU readline in client. Thanks to Jacob Poulsen
1480 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1482 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1483 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1484 IMPLEMENTATION! This change was made to the development version before
1485 the ZIG decided to retract the amendment. If any users MUST be
1486 compatible with the original Update definition, PLEASE CONTACT US, and
1487 we will include a separate definition corresponding to the old Update
1488 ES. Note that because of the change to the ASN.1 of the
1489 TaskPackageRecordStructure we cannot define a single structure that
1490 will support both versions.
1492 * Added const modifier to buffer parameter for some ODR/BER encoding
1493 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1494 completeWAIS, odr_dumpBER.
1496 Fixed bug in client.c which caused a crash when a scanResponse didn't
1497 contain positionOfTerm.
1499 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1500 * will cause an error in a client if a non-YAZ target sends both a
1501 * list of Scan entries and non-surrogate diagnostics.
1503 Retrieval module enhancements. Tag sets may be typed in the reference
1504 to it. From the .abs-file the "tagset" directive takes a third optional
1505 integer type for the tag set referenced. From a .tag-file the "include"
1506 directive takes a third optional type as well. The old "type" directive
1507 in the tag set itself is still recognized but acts as the default type
1510 Backend interface change. Individual Scan terms returned from bend_scan
1511 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1512 in include/backend.h.
1514 Retrieval module enhancements. Multiple tag sets and attribute sets may
1515 be specified in abstract syntax specs. Revised the error/warning for
1516 logging messages reported by the retrieval module when reading the
1519 Object Identifier system (oid_..) changed. The API is backwards
1520 compatible but the oid-routines now allocates new OID's when needed.
1521 Raw OID's may be specified in oid_getvalbyname.
1523 YAZ now uses GNU configure to generate Makefile(s).
1525 * Minor changes in some of the member names of DeleteResultSetRequest and
1526 DeleteResultSetResponse. See include/proto.h.
1528 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1529 and added member 'languages' in TargetInfo (which was missing).
1531 Changed the way attribute sets are handled in the retrieval
1532 module. These are now cached, just like the abstract syntaxes
1535 Changed YAZ so that it links with compiled ASN.1.
1537 Added Explain-schema definitions and mapping routines. The following
1538 Explain categories have been implemented: AttributeDetails,
1539 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1541 Fixed minor bug in Windows version of Server Library.
1543 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1545 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1547 Added EXTERNAL: UNIverse Resource Report (non-standard).
1549 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1550 ENUMERATED and SET OF.
1552 * Added 'const' to some of the char pointer arguments for the
1553 functions, data1_read_node, data1_getelementbytagname,
1554 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1557 Fixed bug in data1_insert_taggeddata - the last_child member of
1558 parent wasn't initialised.
1560 * Changed data1_read_record and data1_read_node so that the supplied
1561 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1562 doesn't refer to any parts of the "SGML"-buffer.
1564 Fixed bug in server library (Windows version of statserv_remove).
1566 * Changed code so that it compiles as C++. The type definition
1567 of Odr_fun which is a member of Odr_arm was changed. The result is,
1568 that an explicit typecast is needed for the fun pointer when
1569 using Odr_arm - as in:
1570 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1572 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1574 Implemented the new structured date and time definition as approved
1575 by the ZIG. Added schemaId element to the specificTag in Espec-1
1576 (also approved at the last ZIG). Thanks to RVDM.
1578 Added some Object identifiers (RVDM).
1580 Changed the Update Extended Service (RVDM).
1582 Added command "refid" to client which specifies referenceId for
1583 the following requests.
1585 Implemented extended service handling for server. See ztest.c
1586 for an example as well as backend.h. New handlers are registerd
1587 in the Init handler.
1589 * Changed interface for sort in server.
1591 Added new members to statserv_options_block. It allows a server
1592 to read options from another source than just the command line. Thanks
1593 to Charles Woodfield.
1595 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1596 renamed to zboolean. Some C++ compilers complained about the name.
1598 Minor changes to gils.abs. Added index 's' (sort) on title
1599 and date/time-last-modified.
1601 --- 1.4pl2 1998/1/30
1603 Fixed bug in server library regarding inetd mode (-i). This bug
1604 was introduced by release 1.4.
1606 --- 1.4pl1 1998/1/29
1608 Added sort facility in client and backend server interface.
1610 Fixed problem with dependencies in Makefile(s).
1612 Fixed bugs for encoders/decoders of extended services and
1615 Implemented sub-tree feature for schemas. Sub-trees are
1616 referenced in *.abs-files. See explain.abs for an example
1617 of the use of this feature.
1619 Modified bib1.att; local attributes for ANY didn't include
1620 ANY itself (only affects use of the retrieval module).
1622 Fixed bug in plain SGML reader in function data1_read_node:
1623 tags with prefix "var" was incorrectly interpreted as variants.
1625 Added feature "sub-schemas" to enable references to - and definitions
1626 of - group of elements.
1628 * Removed member parent from type data1_element (in data1.h).
1630 Implemented function odr_nullval() that returns the value of
1633 * Removed member num_children from data1_node (in data1.h).
1635 Made NT service interface part of the server library. The
1636 function statserv_main uses the NT service when required and
1637 calls the statserv_start / statserv_close routines.
1639 Routine zget_SearchRequest and zget_PresentRequest fills
1640 resultSetName/Id member with "default" instead of "Default".
1642 Fixed memory leak in server. Request queue member wasn't freed.
1644 Fixed nmem_exit so that memory is freed.
1648 Revised the CCL parser utility to be thread safe.
1650 Added function, oid_ent_to_oid, to replace the function
1651 oid_getoidbyent, which is not thread safe.
1653 * Added nmem_init and nmem_exit to initialize and release
1654 NMEM resources. Function nmem_init should be called once in the
1655 initial thread before NMEM/ODR is used. statserv.c and client.c
1656 have been changed accordingly. The change was necessary to make
1657 NMEM thread safe. The NMEM memory pool is shared amongst threads
1658 in a process. Unix-based applications will still work fine without
1661 Added NT Services interface for the the Z39.50 (statserv) Server.
1662 Refer to the ztest.c source on the usage.
1664 Windows 95/NT port using MSVC5.0. Project files are included in the
1667 * Defined new 'global' handle for the retrieval (data1) system. The
1668 new handled, data1_handle, describes the state of the data1 system.
1669 This handle is passed as first argument to virtually all
1670 data1 related routines. The functions data1_create and data1_destroy
1671 creates and destroys a data1 handle respectively.
1673 Added ODR encode stream member to all backend request structures
1674 init, search, scan etc. This stream should be used to allocate all
1675 memory used for the response when thread safe operation is needed.
1677 Changed the comstack utility, cs_addstr, to be thread safe. The
1678 returned hostname string returned by the function is now part the
1681 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1682 function. The cs_straddr takes a COMSTACK handle as argument, so this
1683 function must be used after cs_create and before bind/connect.
1684 This function is thread safe.
1686 Moved test server to 'ztest' directory - generic server code still
1687 in 'server' directory.
1689 Made prefix query (pquery.c) utility thread safe.
1691 Added new function modifier YAZ_EXPORT to 'export' public DLL
1692 functions when using windows (see include/yconfig.h).
1694 Added definitions to the OID database (util/oid.c) (RVDM).
1696 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1698 Added call to ccl_rpn_delete in client program.
1700 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1701 release of RPN structure.
1703 Added support for C++, headers uses extern "C" for public definitions.
1704 With input from RVDM.
1706 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1707 Thanks to Ronald van der Meer (RVDM).
1709 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1711 Added support for private extensions to the OID database
1712 (oid_setprivateoids()). Thanks to RVDM.
1714 Added optional, physical ANY (key replication)
1716 Fixed null-reference problem in GRS-1 output filter.
1718 Proximity operator added to Prefix Query Format (PQF).
1720 In test client command "base" accepts multiple databases.
1722 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1726 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1728 Smallish bug-fixes in the new encoders/decoders (explain).
1730 Bug fixed in DeleteRequest.
1732 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1734 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1736 Added SOIF syntax (using private OID for now) to retrieval module and client.
1738 Added Update extended service.
1740 Added SearchResult-1 additional info structure.
1742 Added optional CCL (ISO8777) interpreter as separate module. Available
1745 --- 1.2 1996/6/10 (1st anniversary release)
1747 Added Summary record syntax. Lightly tested.
1749 Added OPAC record syntax. Untested.
1751 Added ResourceReport service encoders/decoders. Untested.
1753 Fixed bug in z_Unit - wrong tagging on unitSystem.
1755 Fixed bug in the DiagRecs decoder.
1757 Added options for max PDU size and session timeout to frontend-server.
1759 Added documentation of query-language parsers and other supporting utilities.
1761 [frontend-server] Added Attribute set to the bend_scanrequest API.
1763 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1764 surrogate diagnostics were generated.
1766 [retrieval] Allow multiple local values for attribute.
1768 [retrieval] Allow multiple attributes per element in .abs files. index type.
1770 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1772 --- 1.1pl2 1996/4/10
1774 Minor changes, mostly specific to Zebra's requirements (retrieval)
1778 Repaired bug in frontend server when running multiple listening
1779 endpoints in dynamic mode.
1781 z_External() now won't break if a known, ASN.1 value comes encapsulated
1782 in an octet-string. The value will pass through unmodified in an Odr_oct.
1784 Added a bit of code to the demo client to decode & display
1785 ASN.1-structured records represented in the octet-aligned branch of
1786 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1788 Added z_ext_getentbyref() to the ASN module. Doc updated.
1790 * Completed the SCAN definition in the ASN module. This may break SCAN
1791 code based on older YAZ-versions at compile-time. The fix is easy -
1794 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1795 under the SCAN definition. Remember to initialize this, server-people.
1797 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1798 that this does not extend to ODR and ASN.
1800 Comstack allows insertion of established socket (primarily for
1801 inetd-operation of servers). Doc updated.
1803 Front-end server can now start from the inetd in TCP mode. Doc
1806 --- 1.0pl4 1996/1/24
1810 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1811 the rank and record number.
1813 Adjustments to the frontend server.
1815 Fixed diagnostic BER dumper. It ignored the file argument.
1819 Various changes to retrieval module.
1821 Changed the union discriminators of the protocol files from enums to
1822 ints paired with #defines.
1824 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1827 *Changed operator in the RPN structure to 'roperator', again to avoid a
1830 Fixed problems in Explain decoders/encoders.
1832 --- 1.0pl2 1995/12/6
1834 Memory bug in log module fixed.
1836 --- 1.0pl1 1995/12/5
1838 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1840 Bug in Explain DatabaseInfo module fixed.
1842 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1846 The shift to v1.0 signals that we now consider the *core* functionality
1847 of YAZ reasonably stable (the core being more or less equivalent to
1848 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1849 tested (Explain not at all - though that will happen soonish).
1851 Minor changes to code to support Windows port.
1853 Various minor changes after we're getting to use GRS-1 & co. more.
1855 Added Espec-1 format.
1857 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1858 of the protocol and it cannot be selected when encoding (maps into 'string'
1859 when decoding). Needed to talk to some servers.
1861 Demo client can request simple element set names.
1863 Added Diagnostic Format encoders/decoders.
1865 Added simple Close handling to frontend server (no hooks for resource
1866 reporting yet), and demonstration client.
1868 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1870 --- 1.0b3 1995/08/24
1872 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1873 handled incorrectly when records were requested in the searchResponse. This
1874 will only affect you if you use the frontend-server.
1876 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1877 Test-client will ask for and print GRS1. Ztest will return dummy records
1880 Added Explain encoders/decoders to the service-level API. Untested.
1882 Added Extended Services: Item Order encoders and decoders to the Service-
1883 level API. Untested. We could use a recent copy of the pertinent bits
1884 of the ILL protocol to add those bits.
1886 Added diagnostic format 1 encoders/decoders to the service-level API.
1889 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1890 odr_cons.c, which causes a more correct output.
1892 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1893 was always set to 0 when no records were requested in the searchRequest.
1895 * Added better external-handling. This shouldn't harm old code that
1896 *encodes* externals. It can break code that looks for a
1897 'single-ASN1-type' representation, since those types that are known
1898 are now decoded immediately. Look at the SUTRS sample code in
1899 seshigh.c and client.c. Documentation updated.
1901 Handling of structured records in bend_fetchresponse. Length -1 marks
1902 structured record, type is deduced from format field.
1904 --- 1.0b2 1995/06/27
1905 Fairly quick maintenance release to add SUTRS support.
1907 Fixed handling of SUTRS records in the demonstration client.
1909 * Added format field to the bend_fetchrequest and bend_fetchresponce
1910 structures of the backend API (frontend server). When the record is
1911 returned, the value of the format field is mapped to an OID. The
1912 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
