1 Added support for specifying the max log file size for the Generic
2 Frontend Server. The size is given with option -r.
6 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
10 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
13 Fixed bug in Generic Frontend Server that could cause a server to stop
14 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
16 For the generic frontend server, the maximum record size is used as maximum
17 size of incoming packages (SRU + Z39.50). The value until was previously
18 only used in Z39.50 Init negotiation and, later, in a session controlled
19 sizes of records returned. This is controlled using -k option. It can be
20 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
24 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
27 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
29 New option for yaz-marcdump -lpos=value which allows setting a portion
30 of MARC header to a certain value.
32 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
34 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
35 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
39 Fixed problem with SRU mode type (soap, get, post) for yaz-client
42 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
46 Fixed MARC ISO2709 encoding routines to deal with character set
49 Minor changes to GFS logging. Database included in search request log
52 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
53 cached/multiple records.
55 Shared libraries are built by default on Unix+configure.
57 Changed cql2pqf transformation to use a different evaluation order. The
58 new order is: always, relation, structure, position, truncation, index
59 and relationModifier. Old order was: always, relation, relationModifier,
60 structure, index, position, truncation. Note that the the latter ones
61 override former ones for identical attributes.. The new scheme means that
62 it is possible to override any existing attribute with a relationModifier.
63 And also that it is possible to override everything for the index rule
64 (except the ones listed in relationModifier). No order is perfect but this
65 one, we believe, covers more real cases.. The "always" should have been
66 called "default", since the attributes there can be overridden with all
69 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
70 compilation phase, but also for yaz-config --cflags output. This allows
71 us to have public headers with Libxml2 stuff in them . It should also,
72 eventually, make Libxml2 checks redundant in packages using YAZ, such
77 Changed SRU update structure bend_update_rr so that SRU diagnostics are
78 stored in uri, message and details.. Previously diagnostics were stored
79 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
80 compatibility.. but he's probably the only one affected, so.
82 Added support for CCL, compiled on the client side, in ZOOM-C. This
83 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
84 input; the resulting query objects can be used for for searching with
85 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
87 YAZ' configure searches for OpenSSL by default.
89 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
90 SL_CTX_use_certificate_file. See
91 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
92 for more info. Thanks to Ko van der Sloot.
96 Bug #600: SRU GET, POST support for yaz-client. Introduced
97 command 'sru' which selects method SOAP/GET/POST.
99 Allow missingValueAction to be specified for the sortspec string -
100 function yaz_sort_spec. By default, the missing value action is null.
101 Use ! to specify "abort". Use = followed by stringvalue to specify default
104 Ensured that Present-handler (if defined) is called in GFS before any call to
105 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
106 searchRetrieve requests.
108 Documentation for YAZ is now based on the Docbook XML/XSLT using
109 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
110 is no longer depending on jade/openjade or docbook-to-man scripts.
111 PDF is no longer part of the distribution - but can optionally be
112 made using DSSSL/jadetex or FOP.
114 Added retrieval handling support in Generic Frontend Server to support
115 conversion between MARC/XML as well as XSLTtransforms. See
116 etc/yazgfs.xml for an example.
118 Added Authentication support to Generic Frontend Server in SRU
119 mode. Authentication using HTTP Basic is supported, as is the use
120 of 'x-username' and 'x-password' parameters in the request itself.
122 Added support for a new character set MARC8s identical to MARC8 except
123 that it converts combined characters to single Unicode characters in the
124 Latin-1 range (when possible).
126 --- 2.1.18 2006/04/24
128 ASN.1 compiler 0.4: generates brief Doxygen file header for
129 generated .h/.c files.
131 Utility yaz_iconv now supports conversion to MARC-8.
133 New facilities for the MARC module. The reading - and writing of
134 content are separate methods for the yaz_marc_t handle. The following
135 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
136 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
137 format). Write functions have prefix yaz_marc_write_.. The existing
138 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
139 available. Removed support for OAI-MARC and simplexml (not the
140 simplexml from PHP5).
142 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
143 to be returned for this connection.
145 --- 2.1.16 2006/03/31
147 Allow multiple languages and charsets to be specified with
148 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
149 negcharset iso-8859-1,utf-8
151 Translation of proximity nodes from CQL into PQF now works.
153 Moved to automake 1.8, 1.9.
155 Added function yaz_log_set_handler which allows a log handler to be
156 installed. This handler will be called for all log messages. Output
157 to file is also produced; but that can be disabled by passing NULL
158 fname to yaz_log_init_file.
160 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
162 For SRW (including GFS), accept application/soap+xml as content-type
165 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
166 produces NO stylesheet reference even if a default stylesheet is specified
169 --- 2.1.14 2006/03/14
171 Updated Windows package to include yazd.dll + yazd.lib for the
172 Development component.
174 If the environment variable YAZ_LOG is set, then it is used as a
175 string indicating the default level of logging to use if not
176 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
177 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
178 used as before. So, for example, to omit warnings from YAZ logging,
181 cql_transform() now map structure and other attributes before indexes,
182 so that index-specific structures and other attributes can override
183 defaults. So now a combination of mapping specifications such as:
185 index.dc.date = 1=date-modified 4=5
186 does the right thing.
188 cql_transform() now also respects the "always" mapping specification,
189 which establishes an initial set of attributes to be used for all
190 terms except where overridden by more specific attributes associated
191 with the index, relation or modifier.
193 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
194 which mode to use; one of "post", "get" or "soap" (SRW, default).
196 Fixes for yaz_iconv routines: changed trie-based character set conversions
197 to use only non-negative values for bit fields due to Sun's C compiler not
198 supporting negative values.
200 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
201 sequences where not read correctly. Fix by Rustam Usmanov.
203 Updated win/makefile to use options, settings which makes things
204 compile with VS C 2005.
206 --- 2.1.12 2006/02/01
208 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
210 In ZOOM socket code, use select instead of poll on MacOSX.
212 ZOOM-C now support client-side compilation of CQL into RPN that is
213 sent to the server, enabling CQL to be used against all Z39.50
214 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
215 ZOOM_query object, and submit it using ZOOM_connection_search().
216 The CQL-to-RPN translation uses a configuration file, the name of
217 which must be specified in the Connection's "cqlfile" option.
219 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
220 function, which takes as its start-term parameter a ZOOM_query object
221 (which may have had either CQL or RPN set into it).
224 --- 2.1.10 2005/11/29
226 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
227 GFS to support this as well. Backend handler, bend_srw_update, does the
228 update work. Code contributed by Ko van der Sloot.
230 Allow retrieval of Search Result-1 information in ZOOM by the use of
231 options that are attached to a result set. ZOOM documentation updated
234 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
235 UTF-8 conversion. Patch by Raj Patel.
237 Added option -m to GFS to control formatting of timestamps in log file.
239 Added 'exit' as synonym for 'quit' in yaz-client
241 Added support for specifying SRW resultSetId + resultSetIdleTime in a
242 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
243 for the new members. Patch by Ko van der Sloot.
245 Added support for SRU POST. It is supported for content-type
246 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
248 Do not build the separate Multi-threaded (MT) library libyazthread.la.
249 Instead make the library libyaz.la multi-threaded. Threading as a whole
250 can still be disabled by configure option --disable-threads. Previosly,
251 with older GLIBCs there were problems with MT libs under Apache. This
252 has now been fixed a long time ago.
254 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
257 CQL module modified to be case insensitive for relations/indexes/operations.
259 Fixed bug in CQL transform code: incorrect value relationModifieder
262 Added 'show all' command for yaz-client which retrieves all results
265 Added new yaz-client, xmles, which takes a (private) OID and
266 a document to be sent as an extended service request.
268 Describe new yaz-client commands wait_response and set_auto_wait.
270 Increase TCP/IP listener backlog from 3 (which I am guessing was
271 copied from the SunOS manual entry way back when) so SOMAXCONN, so
272 that the socket will queue as many incoming connections as it's able
273 to handle ongoing connections. In other words, it will never now
274 refuse a connection that it would be able to handle merely because
275 it's not got around to accepting() enough of the pending connections
276 yet. This is the behaviour anyway under Linux, where the listen()
277 argument is ignored; but not under BSD and on systems such as
278 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
279 YAZ-based servers should now be uniform across operating systems in
282 yaz-marcdump uses 64-bit file access on some systems. This is enabled
283 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
284 This allows yaz-marcdump to read large MARC batches (>2 GB).
286 Modified all YAZ source files - except the source which is auto-generated
287 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
290 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
291 corresponding to the existing *_setl() function. These allow option
292 values containing arbitrary valuues.
294 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
295 ZOOM_resultset_sort() in new applications. Its behaviour is identical
296 except that it returns an indicator of whether or not the sort
297 criterion was accepted (0 for OK, -1 for invalid).
301 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
302 MARC output rather than returning "new" buffer.
304 yaz-client warns about unknown init options.
306 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
310 Added support for SRW sort in Generic Frontend Server. Patch
311 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
312 sortKeys - or NULL if none is provided.
314 Fixed bug #307: It was impossible to specify indefinite/no timeout
315 for ZOOM_event. Special timeout value -1 now means indefinite timeout
318 Added support for multiple languages and charsets to be specified in
319 ZOOM. Each charset/language is separated by a blank. If negotiation is
320 in effect in init-response, Option
321 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
322 Code based on patch by Vasiliy Osadchuk.
324 Fixed bug #306: infinite recursion that occurred when calling
325 yaz_log_level_init as the first call (before other log level or
328 Fixed bug in scan handling in front end server: if preferred-Position-In-
329 Response was non-present, a NULL pointer referece was performed.
333 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
334 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
335 now defined for all those error codes. So instead of putting 109 in
336 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
337 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
339 Modified the yaz-marcdump utility to skip garbage bytes between MARC
342 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
344 Program yaz-client now exits and produces an error message if multiple
345 Z39.50 servers are specified on the command line (none or one allowed
348 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
353 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
355 Fixed bug #272: Preserve spacing for CCL terms.
359 Added support for virtual hosts and multiple backend servers for
360 the YAZ frontend server. The configution is XML based and
361 support specificition of CQL to RPN mappings and explain information.
362 See section "Virtual Hosts" in the YAZ manual.
364 Extended OPAC display utility. OPAC display utility renders
365 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
366 to supplement yaz_marc_decode_wrbuf.
368 Fixed a bug in MARC decoder that could caused it to crash for some
369 invalid MARC records. More diagnostics and warnings where added in
370 XML output (warnings, etc are stored in comments).
372 --- 2.0.34 2005/02/08
374 Fixes for UNIX domain sockets. Bug #261.
376 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
378 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
379 Added yaz_marc_subfield_str which defines subfield lead string which is
380 used in YAZ_MARC_LINE format. Default string is blank+$. Added
381 yaz_marc_endline_str which defines end of fields string used in
382 YAZ_MARC_LINE format. Default string is newline.
384 Experimental support for MarcXChange. This format can be produced
385 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
386 http://www.bs.dk/standards/MarcXchange.xsd
388 Added yaz-client commands scansize that sets maximum number of
389 entries to be returned by scan.
391 --- 2.0.32 2005/01/11
393 Added support for SRW scan in yaz-client and Generic Frontend Server.
395 * Added whereInList member to SRW Scan Term.
397 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
399 Fixed NMEM system to return aligned blocks on the smallest boundaries
400 that are suitably aligned for all possible types on the particular
401 architecture YAZ is being built for.
403 --- 2.0.30 2005/01/04
405 Fixed numerious warnings that was issued with newer versions of GCC.
407 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
408 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
411 Make YAZ Generic Frontend Server slightly faster.
413 Enhance (and reduce) logging for Generic Frontend Server.
415 Revert YAZ log system so that it flushes every write operation
416 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
418 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
419 instead of LOG_, due to name clash with syslog(3). LOG_ are still
420 present. New applications should define YAZ_USE_NEW_LOG=1 - this
421 will effectively disable old definitions.
423 --- 2.0.28 2004/11/09
425 Added yaz_log_time_format which specifies log format using
428 Added yaz_log_module_level which returns mask for a module. Value
429 is non-zero mask a if module is enabled; zero if disabled.
431 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
432 in include/yaz/cql.h.
434 Fixed bug #176: Dont throw diagnostics on empty SRU args.
436 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
438 Fixed bug #172: RPM builds does not enable SSL.
440 Doxyfile.in part of dist. Doxyfile generated by configure.
442 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
443 are given and the corresponding component does not exist.
445 Extend CCL documentation in YAZ reference. Describe r=r.
447 --- 2.0.26 2004/10/01
449 Fixed MARC->MARCXML conversion to properly deal with
450 fields, subfields, indicators having non-ASCII characters.
452 Fixed MARC->MARCXML conversion so that ASCII control characters
453 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
456 Added YAZ GFS support for conversion from Z39.50 surrogate
457 diagnostics to SRW surrogate diagnostics.
459 Bug fix: YAZ GFS did not return schema in explainResponse.
461 --- 2.0.25 2004/09/30
463 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
464 now converts recordSchema to elementSetName as well as schema URI.
466 Fixed bug in COMSTACK that prevented HTTP request packages from being
469 --- 2.0.24 2004/09/29
471 Added CCL facility r=r "range" which is similar to r=o "ordered" but
472 does not require white-space before and after the dash in a range, e.g.
473 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
476 Fixed a few AC_TRY_LINK configure tests that did not operate properly
477 due to new GCC removing "redundant" code.
479 Added yaz-client commands scanpos and scanstep that sets preferred
480 position and step-size for scan.
482 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
484 Added CCL utility ccl_qual_buf which parses one or more CCL
485 spec lines in a buffer.
487 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
488 of name and value - ignoring empty lines and comments.
490 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
492 Added odr_get_element_path which returns current element path for an
493 ODR handle. This utility is useful in error handling or user-defined
496 Added ODR_PRINT utility odr_set_stream which is is a more generic
497 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
498 to a write function and pointer to close function. The close function - if
499 non-NULL - will be called during odr_destroy.
501 Fixed bug in CCL parser where truncation char was not removed from
502 right side when truncation=both was in effect.
504 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
507 --- 2.0.23 2004/08/11
509 Fix buffer overrun in CQL parser when dealing with proximity (%).
511 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
512 to UTF-8/UCS conversion is now only based on codetables.xml.
514 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
516 --- 2.0.22 2004/08/06
518 Add support for more "commit changes" in ZOOM (uses Extended Services).
520 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
523 Yet another small fix for configure of SSL.
525 --- 2.0.21 2004/05/14
527 Fix SSL libs for configure when --with-openssl=DIR is given.
529 --- 2.0.20 2004/05/10
531 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
533 SSL comstack now uses yaz.pem certificate file on server side
534 by default. Certificate filename can be configured by calling
535 comstack function cs_set_ssl_certificate_file before cs_bind is used.
537 Fix bug regarding multiple calls to ZOOM_connection_connect.
539 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
541 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
542 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
544 ZOOM now allows inspection of X509 peer certificate for verification.
545 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
547 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
548 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
549 as "modular" but it simplifies things.
551 Added cs_get_peer_certificate to that returns peer X509 PEM.
553 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
554 NULL if SSL is unavailable.
556 Documentation about MARC decoding tools.
558 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
560 --- 2.0.19 2004/03/30
562 Rename CHANGELOG to NEWS to follow GNU style packing.
564 Fix bug with missing initialization of member in init_diagnostics.
565 This bug affects threaded version of GFS server.
567 --- 2.0.18 2004/03/20
569 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
572 Ensure zlib.dll is packed with Windows install.
574 --- 2.0.17 2004/03/17
576 Fix encoding of xsd:string to use text instead of CDATA.
578 Fix endless loop in CQL parser with unbalanced ".
580 Use a more compact way to store MARC-8 conversion tables.
582 --- 2.0.16 2004/03/16 Debian only
584 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
587 Update CQL parser to use new CQL 1.1 modifiers for booleans and
592 --- 2.0.15 2004/03/01
594 Another fix for decoding of XML packed records.
596 --- 2.0.14 2004/02/25
598 Fixes for Chunked encoding. White space not ignored after length spec.
600 Update NS and use default NS for SRW diagnostic elements.
602 --- 2.0.13 2004/02/23
604 Implement ZOOM_resultset_cache_reset which resets record cache.
606 Implement ZOOM_resultset_sort which sorts a result set.
608 Implement chunked HTTP transfer.
610 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
612 --- 2.0.12 2004/02/16
614 Added member 'schema' to bend_explain_rr structure so that backend
615 can specify explain record identifier. Defaults to Zeerex 2.0.
617 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
619 --- 2.0.11 2004/02/16
621 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
624 Added init command for yaz-client which sends "extra" init request.
626 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
627 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
629 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
631 Make ZOOM error code for "invalid query".
633 Fixed compilation for SSL which wasn't properly enabled for all platforms.
635 --- 2.0.10 2004/02/05
637 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
640 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
642 Added option -p <file> to make Generic Frontend Server to write PID file.
644 Added option -D to put Generic Frontend Server in background on its own.
646 Make ZOOM C recognize option "password". If unset, "pass" is used
647 (for backwards compatibility).
649 Fixed a bug in Generic Frontend Server that could make it crash if a
650 client sets characterSetNegotation bit, but didn't pass negotiation stuff
653 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
654 Must be issued before open, in order to be in effect.
656 --- 2.0.9-6 2004/01/12 Debian/Windows
658 Make the SRU server more picky WRT unknown params, etc.
660 Bug fix: ZOOM scan response didn't return displayTerm - when present.
662 New YAZ client command, options, that sets Z39.50 options.
664 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
665 options from a string of tokens (one token for each option bit).
667 Update SRW diagnostic code messages.
669 --- 2.0.9-5 2004/01/07 Debian/Windows
671 Handle user defined stylesheet for SRW/SRU.
673 --- 2.0.9-4 2004/01/06 Debian/Windows
675 Fix bug in decoding of Content-Length.
677 --- 2.0.9-3 2004/01/06 Debian/Windows
679 Fix a bug with decoding of XML packed records.
681 --- 2.0.9-2 2004/01/05 Debian only
683 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
685 Fix bug in SRW/SRU diagnostics decoding.
689 Fixed bug in Generic Frontend Server which could drop records exceeding
690 preferred message size. Reported and fixed by Irina Dijour.
692 Fixed calculation of package size for structured records in Generic
693 Frontend Server. Reported and fixed by Irina Dijour.
695 Fixed namespace for SRW/SRU diagnostics.
697 Fixed SEGV in yaz-client that occured for HTTP connection errors.
701 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
702 this version is incompatible with version 1.0 and older YAZ SRW/SRU
705 CQL changes to reflect recent changes to the specification:
706 * Documentation talks about context sets instead of index sets.
707 * Documentation talks about indexes instead of qualifiers.
708 * The CQL-to-PQF transformer's configuration file now uses
709 "index.set.name = <attributes>" instead of the old form
710 "qualifier.set.name = <attributes>". (Both forms are still
711 understood but the latter is deprecated.)
712 * CQL terms with no explicit index specified are now interpreted as
713 cql.serverChoice instead of srw.serverChoice (which of course
714 behaves exactly the same.)
718 MARC conversion can now generate ISO2709 output in another
719 character set. yaz-marcdump uses this facility if you invoke it
722 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
723 functions from there can be used from C++.
727 Frontend server now transfers memory from decoded packages to stream
730 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
731 references to show up.
733 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
734 the ZOOM Abstract API. The older names for the same options are still
735 also supported for the benefit of old applications.
737 ZOOM-C supports "implementationId" and "implementationVersion" options
738 to go along with "implementationName". These allow the user code to
739 specify identification strings to be sent to servers.
740 Add OID for the new ExtLite attribute set.
742 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
743 as requested/supplid by Ere Maijala <ere@atp.fi>
745 For generic frontend server, reverse the order of
746 "toolkit-supplied / application-supplied" strings sent as implementationId,
747 Name and Version. Also, remove the spaces around the slash. This brings
748 the GFS in line with the behaviour of ZOOM-C on the client side.
750 Add function ZOOM_scanset_display_term.
752 yaz-client shows scan displayTerm if present.
754 Utility yaz-iconv is now installed by default along with the man page
757 Extend configure check for OpenSSL to use pkg-config where available (such
760 Incorporate patch by Morten Bogeskov which allows a Unix file socket
761 server to specify uid/gid/mask for socket using the format
762 unix:[user=uid,][group=gid,][umask=mask,]file=path
763 If file= is omitted the existing format is assumed, e.g.
765 in which case the mask is 0666 (rw for everybody).
767 Major restructure of YAZ source. All source in libyaz is in src directory.
768 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
769 util (utility programs such as ASN.1 compiler, yaz-marcdump).
771 Added man page for utility yaz-marcdump (used to be called marcdump).
772 yaz-marcdump is installed by 'make install'.
774 Fixed a memory leak in Generic Frontend Server that occurred when decoding
775 of incoming package failed.
777 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
779 Change prototype of odr_perror: add const to message string.
781 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
783 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
784 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
785 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
786 DNS lookup. There should not be any compatibility problems with this
787 assuming that blocking=1 or 0 is used.
789 Fix bad reference in UNIX comstack in function cs_addrstr.
791 Fix for compilation on AIX.
793 The generic front-end server (server/seshigh.c) now supports returning
794 Init diagnostics to the client in User-information-field, in
795 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
800 Allow any CQL relation (not just all,any,exact,scr).
802 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
803 that features the same UI.
805 Implemented command update0 in YAZ client which is equivalent to
806 update but uses old of Ext Update ASN.1.
808 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
809 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
810 Previously no OID was used for this info.
812 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
813 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
814 returns 'malformed search term' otherwise.
816 SortResponse member resultCount now set to NULL in sort handler of
819 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
822 Add three new utility functions for translating OIDs between various
823 formats -- symbolic name such as "Usmarc", minus-1-terminated int
824 arrays and dotted strings such as "1.2.840.10003.9.5.1":
825 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
826 char *oid_to_dotstring(const int *oid, char *oidbuf);
827 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
829 Reverted modifications for ES Update definition for z_IU0Update
830 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
831 is back to YAZ 2.0.2.
833 String value attributes for CCL parser.
835 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
836 which their FirstSearch server returns in Init responses, sometimes
837 carrying useful diagnostic information when Init fails. This has the
838 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
839 "z39.50/oclcui.asn", where its definition is somewhat different from
840 what OCLC document on their web-site, as required to interoperate with
843 Support for anonymous authentication in yaz-client. Use the command
846 * Fix the OID of the Index Data-local "admin" Extended Service from
847 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
848 the 1000, which indicates a locally-defined OID, was a mistake.
852 Fix CCL directive @case handling so that it affects string match for
853 both CCL keywords and qualifiers.
855 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
856 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
857 Decoder has been updated with ASN.1 changes as listed in
858 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
859 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
860 z_IUUpdate, remains unchanged.
862 ZOOM_record_get may now return a record in a specific character set.
863 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
864 "from" is the character set of record as returned by target. "to" is
865 the character set to be returned. If omitted, "to" is UTF-8.
867 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
869 New ODR utility, odr_getelement, which returns name of element for
870 which encoding/decoding failed.
872 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
873 in cases where a required element was omitted.
875 Bug fix: some MARC8 sequences were not converted.
877 New ZOOM option "step" which specifies number of records to be
878 retrieved in one chunk. Used in conjunction with "start" and "count".
880 SRW support for yaz-client. Use scheme http: to use it, e.g.
883 yaz-client no longer does (un)intelligent character set conversions
884 by default. Can be enabled with charset and marc_charset commands.
886 xmalloc trace fix for 64-bit systems such as DEC alpha.
888 Solaris 2.6 compile fix.
890 New function, cql_strerror() translates SRW error codes, as returned
891 by cql_transform_error(), into human-readable English strings. Used
892 in yaz-client diagnostics when appropriate.
894 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
895 converts it into a type-1 query which is sent to the server. This
896 makes CQL available for use with all Z-servers, as opposed to the tiny
897 minority that can handle CQL queries themselves.
901 New Debian package layout similar to the Redhat Package layout.
903 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
904 and search result respectively.
908 Redhat package is now several packages: libyaz (runtime libraries),
909 libyaz-devel (development and documentation, and yaz (utility programs).
910 Package spec file by Morten Bøgeskov.
912 New member 'schema' in struct bend_fetch_rr which the name of requested
913 schema (SRW/SRU) for record (or NULL if none was given). The fetch
914 handler MAY set this to reflect the schema of the returned record.
916 New member 'display_term' in struct scan_entry. GFS now sets member entries
917 and allocates scan entries to be filled by user scan handler. In previous
918 version, entries member was allocated by the scan handler. That still works,
919 but the GFS will ignore member display_term - assuming it was NOT set by
920 the handler. The fact that the GFS now allocates the entries both allows
921 for new members and makes a scan handler easier to write.
923 Fix CQL lex buffer overflow.
925 SRW/SRU recordPacking. For SRW default recordPacking is string. For
926 SRU default recordPacking is string.
928 SRU protocol support for frontend server.
930 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
932 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
934 Added scan for the ZOOM shell (zoomsh).
938 * String Identifers for Schemas (Amendment 5).
939 http://lcweb.loc.gov/z3950/agency/amend/am5.html
940 Old definition for schema
941 Odr_oid *schema; /* OPT */
946 Z_InternationalString *uri;
947 #define Z_Schema_oid 1
948 #define Z_Schema_uri 2
951 * resultCount parameter to Sort Response (Amendment 1).
952 http://lcweb.loc.gov/z3950/agency/amend/am1.html
954 Support for SRW 1.0 over HTTP. This is an optional feature and
955 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
958 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
959 on the same port. SRW SearchRetrieveRequests are mapped
960 to bend_init,bend_search,bend_fetch,bend_close.
962 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
964 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
965 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
967 ZOOM connections are SRW based if schem http is used for hostname
968 in connect, e.g. z = ZOOM_connection_new("http://myserver");
969 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
971 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
972 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
973 distance=n, order=true/false, relation=le, prox unit=word. If
974 n is omitted, distance 1 is used.
976 Fixed problem with C compiler include path in wrong order.
978 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
979 on Solaris. Patch from Ko van der Sloot.
981 New MARC decode API. All new functions operate on a yaz_marc_t
982 handle. The most important new functions are: yaz_marc_create,
983 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
984 decode and destroy respectively. Decoder can produce formats
985 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
986 include/yaz/marcdisp.h.
988 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
989 to UTF-8, UCS-32, wchar_t or Latin-1.
991 * Prototypes for yaz_iconv_-functions moved to separate header
992 include/yaz/yaz-iconv.h.
994 Make a few private functions 'static' in unix.c. This prevents
995 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
997 For ZOOM connection, the options targetImplementation{Id,Name,Version}
998 are set when Init Response is received.
1000 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1001 but returns diagnostic set as well.
1003 New function yaz_strerror which is a portable wrapper for
1004 strerror/strerror_r/GetLastMessage.
1006 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1007 is returned for MARC. If type is "oai", then OAI MARC is returned.
1009 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1012 --- 1.9.2 2002/11/26
1014 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1016 Fix bad race conditions on SIGTERM and terminate gracefully in
1019 Move retrieval (data1) module to Zebra since nobody seems to be
1022 Add GRS-1 render for ZOOM using same format as yaz-client.
1024 --- 1.9.1 2002/10/05
1026 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1028 Fix broken ESpec handling in data1 module.
1030 SGML reader parses comments and makes them part of the data1 tree.
1032 Added several type casts so that YAZ compiles as C++ code.
1034 ZOOM didn't handle PDU encoding failures properly.
1036 Added more Bib-1 diagnostics (approved extensions).
1038 GNU configure: better check for iconv.
1040 More portable use of accept, getpeername. Check for socklen_t. Use
1041 int/size_t if socklen_t is not defined.
1045 PQF parser rejects bad queries - including those with extra
1046 characters in them. PQF parser used to silently ignore that.
1047 Cleaner API for PQF added, which allows you to get detailed
1048 error information for bad queries (see yaz/pquery.h).
1050 Fixed bug in ZOOM_record_get for type "database".
1052 Implemented mini iconv library supporting conversions between
1053 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1055 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1057 --- 1.8.9 2002/08/20
1059 Fixed ZOOM C record cache so that preferredRecordSyntax and
1060 elementSetName is used to check for already fetched records.
1062 --- 1.8.8 2002/08/02
1064 Added three members in bend_initrequest structure to facilitate
1065 character set negotiation.
1067 Fixed a bug in frontend server that could cause indefinite
1068 loops under rare conditions.
1070 Revised character set utilities (charneg.h) so that encoding
1071 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1073 For PQF, directive @term <type> sets term type for Scan/Search.
1074 Here <type> is general, string, numeric, null. The term type
1075 is inherited - just like @attr.
1077 New call odr_set_charset that sets character set conversion for
1078 international-strings on a ODR stream. Prototype is:
1079 int odr_set_charset(ODR o, const char *to, const char *from);
1080 The InternationalString is still represented as C string in YAZ
1081 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1082 won't). On the protocol level, you can use any encoding.
1084 Support for UNIX sockets in ZOOM.
1086 Solaris recv sometimes returns errno == ENOENT. It is treated as
1087 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1089 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1090 both client and server. Code by Morten Bøgeskov.
1092 --- 1.8.7 2002/05/22
1094 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1095 that they can be used directly from Visual Basic. You must recompile
1096 your windows APP if you're using ZOOM.
1098 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1099 Commands "lang" and "charset" sets language and character set respectively.
1100 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1101 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1103 Attributes from multiple CCL fields may be OR'ed rather than merged
1104 using directive "@field or". Fields are still merged by default -
1105 equivalent to "@field merge".
1107 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1110 Fixed bug in zget for parameter ExtendedServicesResponse.
1114 --- 1.8.6 2002/03/25
1116 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1118 Client displays USR.1:SearchResult-1 (hits per term).
1120 Additional Search Info for search in Generic Frontend Server.
1122 Fixed CCL parsing of "field=s".
1124 WIN32 installer - using the excellent NSIS software from nullsoft.
1126 Fixed CCL parsing of "field = - <number>".
1128 Added function yaz_marc_decode that decodes MARC for line mode
1129 display or XML (similar to that used by JZKit).
1131 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1132 Z39.50. But ISO/ILL was, however.
1134 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1135 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1137 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1138 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1140 --- 1.8.5 2002/02/03
1142 New YAZ client features: Command completion and new commands:
1143 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1144 Code provided by Jacob Poulsen.
1146 New call oid_trav, that visits all registered OIDs via callback.
1148 Function ZOOM_record_get now returns const char pointer rather than
1149 void pointer. It saves a lot of type casts.
1151 For YAZ client, command "auth" now allows you to set authentication
1152 in IdPass style. It is enabled when three tokens are given - order
1153 is user, group and password.
1155 Fix memory leaks in MARC record handling for ZOOM.
1157 New option for YAZ client, -k <kilobytes> that sets
1158 maximum record size. Similar to -k option for generic frontend
1159 server and yaz-ztest.
1161 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1163 Prefix query parser reports "fail" when bad attribute set is given.
1165 Fix in MARC decoder. Proximity logging. Fix for attribute set
1166 in scan handler for server. Patches by Shigeru Ishida.
1168 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1171 Configure option --with-openssl=<dir> now works when a directory is
1172 specified. Patch provided by Morten Bøgeskov.
1174 New option for YAZ client, -u <auth>, that sets authentication.
1176 ZOOM fix: error information was sometimes "missing", since error
1177 was cleared/reset too when it shouldn't.
1179 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1181 --- 1.8.4 2002/01/04
1183 Scan for ZOOM API. New object ZOOM_scanset. New functions
1184 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1185 ZOOM_scanset_destroy.
1187 New ZOOM function, ZOOM_connection_last_event, that returns type
1188 of last event (such as "receive data", "send data", "apdu received",
1191 New ZOOM option, schema, that specifies schema for retrieval.
1193 New CCL feature. Qualifiers can be aliases for one or more
1194 other qualifiers (if more than one is given, OR is used).
1196 ZOOM uses named result sets if target supports it.
1198 Two new YAZ client commands: . (dot, which sources a script of YAZ
1199 client commands), and ! (to execute shell command.). Implemented
1202 Working on Debian packages.
1204 --- 1.8.3 2001/11/19
1206 YAZ client enables named result sets only if target supports it.
1208 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1210 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1211 with key="host" to get same result.
1213 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1214 Function Z3950_resultset_record(s) returns references to records
1215 "owned" by resultset. To become owner use Z3950_record_clone.
1217 Function z_ext_record handles Extended Services. Thanks to
1220 --- 1.8.2 2001/11/12
1222 CCL Parser fix: ignore token comma when dealing with and-lists.
1224 Documentation updates for COMSTACK.
1226 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1227 Changed prototype Z3950_records. For some functions, int parameters
1228 were changed to size_t.
1230 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1233 New MARC decode/display function, marc_display_exl, which properly rejects
1234 non-ISO2709 records. YAZ client uses it.
1236 --- 1.8.1 2001/10/29
1238 Fix bug: local attribute set wasn't set correctly in PQF strings.
1242 * Old Z39.50 codecs no longer supported.
1244 Added ZOOM C binding. See http://zoom.z3950.org/
1246 Renamed states for COMSTACKs to avoid confusion with events.
1248 Implemented cs_look and proper cs_rcvconnect.
1250 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1252 Configure detects POSIX threads on OpenBSD.
1254 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1255 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1257 When error is returned from present handler, non-surrogate diagnostic
1258 is returned in present response (and fetch handler is no longer called).
1260 * Minor adjustments to pquery parser (PQF). Token characters may be
1261 escaped by using backslash (C-style).
1263 PQF parser allows string attribute values to be specified. For @attr,
1264 non-numeric characters after the equal-sign are treated as strings
1265 (e.g. @attr 9=title).
1267 CCL trunction character may be defined (@truncation in file)
1269 * function zget_ExtendedServicesRequest sets waitAction to
1270 waitIfPossible (was wait).
1272 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1275 CCL operator names may be set in field definition files (CCL_bibset).
1276 See ccl/bib1 for an example.
1278 Fixes in ASN.1 compiler for C++ compatibility.
1280 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1281 and "op_or" to avoid conflict with C++.
1283 Fixed problem with GNU readline detection on Redhat 7.0.
1285 Added step-size for Scan backend handler.
1287 Fixed bug that made the frontend server crash when no attribute
1288 set was specified for scan.
1290 Front-end server automatically switches to original working directory
1291 when installed as an NT service. Previously -w had to be specified to
1294 Added extended attributes for retrieval module (data1), so that data1
1295 records carry d1_readXML/SGML attributes. d1_read also supports
1296 null-data rules ( <tag/>)
1298 On UNIX when POSIX threads are available, a separate library libyazthread
1299 is created. Programmers should link with that library and the yaz library
1300 when using threads. The reason for the split was that some applications
1301 on Linux, such as Apache, doesn't work well when using shared objects that
1304 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1305 (or any frontend server) in SSL mode by specifying ssl: followed by
1306 address. Only tested on UNIX.
1308 Added feature for CCL module. Virtual structure s=al or s=ol generates
1309 and-list and or-list respectively instead of phrase search.
1313 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1314 log_mask_str. This was done to avoid name conflicts with other libraries
1315 (such as other PHP extensions).
1317 Added raw OID member for preferred record syntax (request_format_raw)
1318 and returned record syntax (output_format_raw) for backend fetch method.
1320 Config file yaz-config now accepts options so that it returns specific
1321 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1323 Shared library support for UNIX using GNU libtool.
1325 * Modified backend interface. Request/Response struct's replaced by
1326 one read/write C struct. For example bend_fetchrequest and
1327 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1328 Every handler - even search has to be registered in bend_init
1329 handler. This means that the YAZ library no longer refers to
1330 external functions and it makes it possible to make the whole
1331 thing a single DLL/SO.
1333 Added Segment handler for backend server.
1335 Added Zmbol/Zebra administrative functions to YAZ client.
1337 Threaded frontend server on UNIX (when POSIX Threads are available).
1338 Starting the server with option -T enables multi-threading.
1342 Added configure option --enable-comp/disable-comp to control use
1343 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1344 located in sub directory asn.
1346 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1347 in ${exec_prefix}/bin along with the other programs yaz-client and
1350 GNU automake used to maintain makefiles.
1352 Added several OID's.
1354 Changed retrieval module so that we can load records with no abstract
1355 syntax defined. Tagpaths in these records are fully composed of string
1358 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1362 On UNIX, the generated makefile now supports a proper 'make install'.
1363 The prefix can be set via GNU configure to set the install location
1364 (default is /usr/local).
1366 * YAZ programs client and ztest were renamed to yaz-client and
1367 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1368 locations, such as /usr/bin,/usr/local/bin,etc.
1370 * YAZ Header files were moved from include to include/yaz. YAZ Header
1371 files are referred to as include <yaz/log.h> rather than <log.h>.
1372 The YAZ include path (-I ..) is therefore the same as before. Programmers
1373 should update their #include statements or use -Ipath/include/yaz
1374 instead. The main motivation for doing this change is that YAZ header files
1375 can be installed in "standard" locations /usr/include,/usr/local/include
1376 without introducing conflicts, since ALL YAZ header files are stored
1377 in subdirectory yaz (under /usr/include for example).
1379 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1380 rather than project/workspace files. We switched because project files
1381 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1384 Changed name of logging function, logf, to yaz_log, to prevent name
1385 clash with some math-log functions. The YAZ header log.h defines logf
1386 to yaz_log (#define) so there should be no incompatibilities by this
1389 Added bend_start/bend_stop handlers for server. These handler are
1390 called on start/stop of server. For windows they are called whenever
1391 a service is started/stopped.
1393 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1394 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1395 in util/yc.tcl. The auto-generated C code structures are, in a few
1396 cases, incompatible with the old decoders. There are differences in the
1397 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1398 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1399 The preprocessor variable ASN_COMPILED is defined when the compiled
1400 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1401 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1402 wish to use the old encoders/decoders you can specify --disable-yc
1405 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1406 version so that it supports both new - and old version of DB Update
1408 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1409 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1410 change. The name parameter can be set to 0 in which no name is specified
1411 for the construction. The macros odr_implicit and odr_explicit sets name
1412 parameter to zero for the construction involved. New macros
1413 odr_implicit_tag and odr_explicit_tag are similar to the others,
1414 except that a name parameter is added. For programmers' that don't use
1415 ODR they probably only need to change the call to z_APDU and z_External.
1417 Added access control facility by interfacing the TCP wrapper library.
1418 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1419 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1420 name of the daemon and enables the access control as specified in
1421 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1423 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1424 den Dool <H.M.vdnDool@kub.nl>.
1426 Added reference ID parameter to most functions in server API - refer
1427 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1429 Changed name of ccl library to libccl.a (was ccl.a).
1431 Fixed bug in decoder for Explain (Category TargetInfo).
1433 Added support for GNU readline in client. Thanks to Jacob Poulsen
1434 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1436 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1437 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1438 IMPLEMENTATION! This change was made to the development version before
1439 the ZIG decided to retract the amendment. If any users MUST be
1440 compatible with the original Update definition, PLEASE CONTACT US, and
1441 we will include a separate definition corresponding to the old Update
1442 ES. Note that because of the change to the ASN.1 of the
1443 TaskPackageRecordStructure we cannot define a single structure that
1444 will support both versions.
1446 * Added const modifier to buffer parameter for some ODR/BER encoding
1447 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1448 completeWAIS, odr_dumpBER.
1450 Fixed bug in client.c which caused a crash when a scanResponse didn't
1451 contain positionOfTerm.
1453 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1454 * will cause an error in a client if a non-YAZ target sends both a
1455 * list of Scan entries and non-surrogate diagnostics.
1457 Retrieval module enhancements. Tag sets may be typed in the reference
1458 to it. From the .abs-file the "tagset" directive takes a third optional
1459 integer type for the tag set referenced. From a .tag-file the "include"
1460 directive takes a third optional type as well. The old "type" directive
1461 in the tag set itself is still recognized but acts as the default type
1464 Backend interface change. Individual Scan terms returned from bend_scan
1465 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1466 in include/backend.h.
1468 Retrieval module enhancements. Multiple tag sets and attribute sets may
1469 be specified in abstract syntax specs. Revised the error/warning for
1470 logging messages reported by the retrieval module when reading the
1473 Object Identifier system (oid_..) changed. The API is backwards
1474 compatible but the oid-routines now allocates new OID's when needed.
1475 Raw OID's may be specified in oid_getvalbyname.
1477 YAZ now uses GNU configure to generate Makefile(s).
1479 * Minor changes in some of the member names of DeleteResultSetRequest and
1480 DeleteResultSetResponse. See include/proto.h.
1482 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1483 and added member 'languages' in TargetInfo (which was missing).
1485 Changed the way attribute sets are handled in the retrieval
1486 module. These are now cached, just like the abstract syntaxes
1489 Changed YAZ so that it links with compiled ASN.1.
1491 Added Explain-schema definitions and mapping routines. The following
1492 Explain categories have been implemented: AttributeDetails,
1493 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1495 Fixed minor bug in Windows version of Server Library.
1497 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1499 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1501 Added EXTERNAL: UNIverse Resource Report (non-standard).
1503 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1504 ENUMERATED and SET OF.
1506 * Added 'const' to some of the char pointer arguments for the
1507 functions, data1_read_node, data1_getelementbytagname,
1508 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1511 Fixed bug in data1_insert_taggeddata - the last_child member of
1512 parent wasn't initialised.
1514 * Changed data1_read_record and data1_read_node so that the supplied
1515 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1516 doesn't refer to any parts of the "SGML"-buffer.
1518 Fixed bug in server library (Windows version of statserv_remove).
1520 * Changed code so that it compiles as C++. The type definition
1521 of Odr_fun which is a member of Odr_arm was changed. The result is,
1522 that an explicit typecast is needed for the fun pointer when
1523 using Odr_arm - as in:
1524 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1526 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1528 Implemented the new structured date and time definition as approved
1529 by the ZIG. Added schemaId element to the specificTag in Espec-1
1530 (also approved at the last ZIG). Thanks to RVDM.
1532 Added some Object identifiers (RVDM).
1534 Changed the Update Extended Service (RVDM).
1536 Added command "refid" to client which specifies referenceId for
1537 the following requests.
1539 Implemented extended service handling for server. See ztest.c
1540 for an example as well as backend.h. New handlers are registerd
1541 in the Init handler.
1543 * Changed interface for sort in server.
1545 Added new members to statserv_options_block. It allows a server
1546 to read options from another source than just the command line. Thanks
1547 to Charles Woodfield.
1549 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1550 renamed to zboolean. Some C++ compilers complained about the name.
1552 Minor changes to gils.abs. Added index 's' (sort) on title
1553 and date/time-last-modified.
1555 --- 1.4pl2 1998/1/30
1557 Fixed bug in server library regarding inetd mode (-i). This bug
1558 was introduced by release 1.4.
1560 --- 1.4pl1 1998/1/29
1562 Added sort facility in client and backend server interface.
1564 Fixed problem with dependencies in Makefile(s).
1566 Fixed bugs for encoders/decoders of extended services and
1569 Implemented sub-tree feature for schemas. Sub-trees are
1570 referenced in *.abs-files. See explain.abs for an example
1571 of the use of this feature.
1573 Modified bib1.att; local attributes for ANY didn't include
1574 ANY itself (only affects use of the retrieval module).
1576 Fixed bug in plain SGML reader in function data1_read_node:
1577 tags with prefix "var" was incorrectly interpreted as variants.
1579 Added feature "sub-schemas" to enable references to - and definitions
1580 of - group of elements.
1582 * Removed member parent from type data1_element (in data1.h).
1584 Implemented function odr_nullval() that returns the value of
1587 * Removed member num_children from data1_node (in data1.h).
1589 Made NT service interface part of the server library. The
1590 function statserv_main uses the NT service when required and
1591 calls the statserv_start / statserv_close routines.
1593 Routine zget_SearchRequest and zget_PresentRequest fills
1594 resultSetName/Id member with "default" instead of "Default".
1596 Fixed memory leak in server. Request queue member wasn't freed.
1598 Fixed nmem_exit so that memory is freed.
1602 Revised the CCL parser utility to be thread safe.
1604 Added function, oid_ent_to_oid, to replace the function
1605 oid_getoidbyent, which is not thread safe.
1607 * Added nmem_init and nmem_exit to initialize and release
1608 NMEM resources. Function nmem_init should be called once in the
1609 initial thread before NMEM/ODR is used. statserv.c and client.c
1610 have been changed accordingly. The change was necessary to make
1611 NMEM thread safe. The NMEM memory pool is shared amongst threads
1612 in a process. Unix-based applications will still work fine without
1615 Added NT Services interface for the the Z39.50 (statserv) Server.
1616 Refer to the ztest.c source on the usage.
1618 Windows 95/NT port using MSVC5.0. Project files are included in the
1621 * Defined new 'global' handle for the retrieval (data1) system. The
1622 new handled, data1_handle, describes the state of the data1 system.
1623 This handle is passed as first argument to virtually all
1624 data1 related routines. The functions data1_create and data1_destroy
1625 creates and destroys a data1 handle respectively.
1627 Added ODR encode stream member to all backend request structures
1628 init, search, scan etc. This stream should be used to allocate all
1629 memory used for the response when thread safe operation is needed.
1631 Changed the comstack utility, cs_addstr, to be thread safe. The
1632 returned hostname string returned by the function is now part the
1635 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1636 function. The cs_straddr takes a COMSTACK handle as argument, so this
1637 function must be used after cs_create and before bind/connect.
1638 This function is thread safe.
1640 Moved test server to 'ztest' directory - generic server code still
1641 in 'server' directory.
1643 Made prefix query (pquery.c) utility thread safe.
1645 Added new function modifier YAZ_EXPORT to 'export' public DLL
1646 functions when using windows (see include/yconfig.h).
1648 Added definitions to the OID database (util/oid.c) (RVDM).
1650 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1652 Added call to ccl_rpn_delete in client program.
1654 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1655 release of RPN structure.
1657 Added support for C++, headers uses extern "C" for public definitions.
1658 With input from RVDM.
1660 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1661 Thanks to Ronald van der Meer (RVDM).
1663 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1665 Added support for private extensions to the OID database
1666 (oid_setprivateoids()). Thanks to RVDM.
1668 Added optional, physical ANY (key replication)
1670 Fixed null-reference problem in GRS-1 output filter.
1672 Proximity operator added to Prefix Query Format (PQF).
1674 In test client command "base" accepts multiple databases.
1676 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1680 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1682 Smallish bug-fixes in the new encoders/decoders (explain).
1684 Bug fixed in DeleteRequest.
1686 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1688 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1690 Added SOIF syntax (using private OID for now) to retrieval module and client.
1692 Added Update extended service.
1694 Added SearchResult-1 additional info structure.
1696 Added optional CCL (ISO8777) interpreter as separate module. Available
1699 --- 1.2 1996/6/10 (1st anniversary release)
1701 Added Summary record syntax. Lightly tested.
1703 Added OPAC record syntax. Untested.
1705 Added ResourceReport service encoders/decoders. Untested.
1707 Fixed bug in z_Unit - wrong tagging on unitSystem.
1709 Fixed bug in the DiagRecs decoder.
1711 Added options for max PDU size and session timeout to frontend-server.
1713 Added documentation of query-language parsers and other supporting utilities.
1715 [frontend-server] Added Attribute set to the bend_scanrequest API.
1717 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1718 surrogate diagnostics were generated.
1720 [retrieval] Allow multiple local values for attribute.
1722 [retrieval] Allow multiple attributes per element in .abs files. index type.
1724 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1726 --- 1.1pl2 1996/4/10
1728 Minor changes, mostly specific to Zebra's requirements (retrieval)
1732 Repaired bug in frontend server when running multiple listening
1733 endpoints in dynamic mode.
1735 z_External() now won't break if a known, ASN.1 value comes encapsulated
1736 in an octet-string. The value will pass through unmodified in an Odr_oct.
1738 Added a bit of code to the demo client to decode & display
1739 ASN.1-structured records represented in the octet-aligned branch of
1740 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1742 Added z_ext_getentbyref() to the ASN module. Doc updated.
1744 * Completed the SCAN definition in the ASN module. This may break SCAN
1745 code based on older YAZ-versions at compile-time. The fix is easy -
1748 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1749 under the SCAN definition. Remember to initialize this, server-people.
1751 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1752 that this does not extend to ODR and ASN.
1754 Comstack allows insertion of established socket (primarily for
1755 inetd-operation of servers). Doc updated.
1757 Front-end server can now start from the inetd in TCP mode. Doc
1760 --- 1.0pl4 1996/1/24
1764 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1765 the rank and record number.
1767 Adjustments to the frontend server.
1769 Fixed diagnostic BER dumper. It ignored the file argument.
1773 Various changes to retrieval module.
1775 Changed the union discriminators of the protocol files from enums to
1776 ints paired with #defines.
1778 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1781 *Changed operator in the RPN structure to 'roperator', again to avoid a
1784 Fixed problems in Explain decoders/encoders.
1786 --- 1.0pl2 1995/12/6
1788 Memory bug in log module fixed.
1790 --- 1.0pl1 1995/12/5
1792 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1794 Bug in Explain DatabaseInfo module fixed.
1796 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1800 The shift to v1.0 signals that we now consider the *core* functionality
1801 of YAZ reasonably stable (the core being more or less equivalent to
1802 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1803 tested (Explain not at all - though that will happen soonish).
1805 Minor changes to code to support Windows port.
1807 Various minor changes after we're getting to use GRS-1 & co. more.
1809 Added Espec-1 format.
1811 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1812 of the protocol and it cannot be selected when encoding (maps into 'string'
1813 when decoding). Needed to talk to some servers.
1815 Demo client can request simple element set names.
1817 Added Diagnostic Format encoders/decoders.
1819 Added simple Close handling to frontend server (no hooks for resource
1820 reporting yet), and demonstration client.
1822 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1824 --- 1.0b3 1995/08/24
1826 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1827 handled incorrectly when records were requested in the searchResponse. This
1828 will only affect you if you use the frontend-server.
1830 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1831 Test-client will ask for and print GRS1. Ztest will return dummy records
1834 Added Explain encoders/decoders to the service-level API. Untested.
1836 Added Extended Services: Item Order encoders and decoders to the Service-
1837 level API. Untested. We could use a recent copy of the pertinent bits
1838 of the ILL protocol to add those bits.
1840 Added diagnostic format 1 encoders/decoders to the service-level API.
1843 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1844 odr_cons.c, which causes a more correct output.
1846 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1847 was always set to 0 when no records were requested in the searchRequest.
1849 * Added better external-handling. This shouldn't harm old code that
1850 *encodes* externals. It can break code that looks for a
1851 'single-ASN1-type' representation, since those types that are known
1852 are now decoded immediately. Look at the SUTRS sample code in
1853 seshigh.c and client.c. Documentation updated.
1855 Handling of structured records in bend_fetchresponse. Length -1 marks
1856 structured record, type is deduced from format field.
1858 --- 1.0b2 1995/06/27
1859 Fairly quick maintenance release to add SUTRS support.
1861 Fixed handling of SUTRS records in the demonstration client.
1863 * Added format field to the bend_fetchrequest and bend_fetchresponce
1864 structures of the backend API (frontend server). When the record is
1865 returned, the value of the format field is mapped to an OID. The
1866 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1867 of the record. The special value VAL_NONE in the bend_request means
1868 that no specific format was requested by the client. Documentation
1869 updated accordingly. Test server (ztest) will return a fixed dummy
1870 SUTRS record if your client requests SUTRS.
1872 Documentation updated accordingly.
1874 You can now set external libraries and RANLIB support in the top-level
1878 First public release.
