1 For the generic frontend server, the maximum record size is used as maximum
2 size of incoming packages (SRU + Z39.50). The value until was previously
3 only used in Z39.50 Init negotiation and, later, in a session controlled
4 sizes of records returned. This is controlled using -k option. It can be
5 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
9 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
12 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
14 New option for yaz-marcdump -lpos=value which allows setting a portion
15 of MARC header to a certain value.
17 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
19 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
20 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
24 Fixed problem with SRU mode type (soap, get, post) for yaz-client
27 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
31 Fixed MARC ISO2709 encoding routines to deal with character set
34 Minor changes to GFS logging. Database included in search request log
37 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
38 cached/multiple records.
40 Shared libraries are built by default on Unix+configure.
42 Changed cql2pqf transformation to use a different evaluation order. The
43 new order is: always, relation, structure, position, truncation, index
44 and relationModifier. Old order was: always, relation, relationModifier,
45 structure, index, position, truncation. Note that the the latter ones
46 override former ones for identical attributes.. The new scheme means that
47 it is possible to override any existing attribute with a relationModifier.
48 And also that it is possible to override everything for the index rule
49 (except the ones listed in relationModifier). No order is perfect but this
50 one, we believe, covers more real cases.. The "always" should have been
51 called "default", since the attributes there can be overridden with all
54 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
55 compilation phase, but also for yaz-config --cflags output. This allows
56 us to have public headers with Libxml2 stuff in them . It should also,
57 eventually, make Libxml2 checks redundant in packages using YAZ, such
62 Changed SRU update structure bend_update_rr so that SRU diagnostics are
63 stored in uri, message and details.. Previously diagnostics were stored
64 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
65 compatibility.. but he's probably the only one affected, so.
67 Added support for CCL, compiled on the client side, in ZOOM-C. This
68 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
69 input; the resulting query objects can be used for for searching with
70 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
72 YAZ' configure searches for OpenSSL by default.
74 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
75 SL_CTX_use_certificate_file. See
76 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
77 for more info. Thanks to Ko van der Sloot.
81 Bug #600: SRU GET, POST support for yaz-client. Introduced
82 command 'sru' which selects method SOAP/GET/POST.
84 Allow missingValueAction to be specified for the sortspec string -
85 function yaz_sort_spec. By default, the missing value action is null.
86 Use ! to specify "abort". Use = followed by stringvalue to specify default
89 Ensured that Present-handler (if defined) is called in GFS before any call to
90 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
91 searchRetrieve requests.
93 Documentation for YAZ is now based on the Docbook XML/XSLT using
94 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
95 is no longer depending on jade/openjade or docbook-to-man scripts.
96 PDF is no longer part of the distribution - but can optionally be
97 made using DSSSL/jadetex or FOP.
99 Added retrieval handling support in Generic Frontend Server to support
100 conversion between MARC/XML as well as XSLTtransforms. See
101 etc/yazgfs.xml for an example.
103 Added Authentication support to Generic Frontend Server in SRU
104 mode. Authentication using HTTP Basic is supported, as is the use
105 of 'x-username' and 'x-password' parameters in the request itself.
107 Added support for a new character set MARC8s identical to MARC8 except
108 that it converts combined characters to single Unicode characters in the
109 Latin-1 range (when possible).
111 --- 2.1.18 2006/04/24
113 ASN.1 compiler 0.4: generates brief Doxygen file header for
114 generated .h/.c files.
116 Utility yaz_iconv now supports conversion to MARC-8.
118 New facilities for the MARC module. The reading - and writing of
119 content are separate methods for the yaz_marc_t handle. The following
120 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
121 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
122 format). Write functions have prefix yaz_marc_write_.. The existing
123 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
124 available. Removed support for OAI-MARC and simplexml (not the
125 simplexml from PHP5).
127 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
128 to be returned for this connection.
130 --- 2.1.16 2006/03/31
132 Allow multiple languages and charsets to be specified with
133 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
134 negcharset iso-8859-1,utf-8
136 Translation of proximity nodes from CQL into PQF now works.
138 Moved to automake 1.8, 1.9.
140 Added function yaz_log_set_handler which allows a log handler to be
141 installed. This handler will be called for all log messages. Output
142 to file is also produced; but that can be disabled by passing NULL
143 fname to yaz_log_init_file.
145 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
147 For SRW (including GFS), accept application/soap+xml as content-type
150 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
151 produces NO stylesheet reference even if a default stylesheet is specified
154 --- 2.1.14 2006/03/14
156 Updated Windows package to include yazd.dll + yazd.lib for the
157 Development component.
159 If the environment variable YAZ_LOG is set, then it is used as a
160 string indicating the default level of logging to use if not
161 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
162 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
163 used as before. So, for example, to omit warnings from YAZ logging,
166 cql_transform() now map structure and other attributes before indexes,
167 so that index-specific structures and other attributes can override
168 defaults. So now a combination of mapping specifications such as:
170 index.dc.date = 1=date-modified 4=5
171 does the right thing.
173 cql_transform() now also respects the "always" mapping specification,
174 which establishes an initial set of attributes to be used for all
175 terms except where overridden by more specific attributes associated
176 with the index, relation or modifier.
178 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
179 which mode to use; one of "post", "get" or "soap" (SRW, default).
181 Fixes for yaz_iconv routines: changed trie-based character set conversions
182 to use only non-negative values for bit fields due to Sun's C compiler not
183 supporting negative values.
185 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
186 sequences where not read correctly. Fix by Rustam Usmanov.
188 Updated win/makefile to use options, settings which makes things
189 compile with VS C 2005.
191 --- 2.1.12 2006/02/01
193 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
195 In ZOOM socket code, use select instead of poll on MacOSX.
197 ZOOM-C now support client-side compilation of CQL into RPN that is
198 sent to the server, enabling CQL to be used against all Z39.50
199 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
200 ZOOM_query object, and submit it using ZOOM_connection_search().
201 The CQL-to-RPN translation uses a configuration file, the name of
202 which must be specified in the Connection's "cqlfile" option.
204 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
205 function, which takes as its start-term parameter a ZOOM_query object
206 (which may have had either CQL or RPN set into it).
209 --- 2.1.10 2005/11/29
211 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
212 GFS to support this as well. Backend handler, bend_srw_update, does the
213 update work. Code contributed by Ko van der Sloot.
215 Allow retrieval of Search Result-1 information in ZOOM by the use of
216 options that are attached to a result set. ZOOM documentation updated
219 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
220 UTF-8 conversion. Patch by Raj Patel.
222 Added option -m to GFS to control formatting of timestamps in log file.
224 Added 'exit' as synonym for 'quit' in yaz-client
226 Added support for specifying SRW resultSetId + resultSetIdleTime in a
227 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
228 for the new members. Patch by Ko van der Sloot.
230 Added support for SRU POST. It is supported for content-type
231 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
233 Do not build the separate Multi-threaded (MT) library libyazthread.la.
234 Instead make the library libyaz.la multi-threaded. Threading as a whole
235 can still be disabled by configure option --disable-threads. Previosly,
236 with older GLIBCs there were problems with MT libs under Apache. This
237 has now been fixed a long time ago.
239 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
242 CQL module modified to be case insensitive for relations/indexes/operations.
244 Fixed bug in CQL transform code: incorrect value relationModifieder
247 Added 'show all' command for yaz-client which retrieves all results
250 Added new yaz-client, xmles, which takes a (private) OID and
251 a document to be sent as an extended service request.
253 Describe new yaz-client commands wait_response and set_auto_wait.
255 Increase TCP/IP listener backlog from 3 (which I am guessing was
256 copied from the SunOS manual entry way back when) so SOMAXCONN, so
257 that the socket will queue as many incoming connections as it's able
258 to handle ongoing connections. In other words, it will never now
259 refuse a connection that it would be able to handle merely because
260 it's not got around to accepting() enough of the pending connections
261 yet. This is the behaviour anyway under Linux, where the listen()
262 argument is ignored; but not under BSD and on systems such as
263 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
264 YAZ-based servers should now be uniform across operating systems in
267 yaz-marcdump uses 64-bit file access on some systems. This is enabled
268 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
269 This allows yaz-marcdump to read large MARC batches (>2 GB).
271 Modified all YAZ source files - except the source which is auto-generated
272 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
275 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
276 corresponding to the existing *_setl() function. These allow option
277 values containing arbitrary valuues.
279 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
280 ZOOM_resultset_sort() in new applications. Its behaviour is identical
281 except that it returns an indicator of whether or not the sort
282 criterion was accepted (0 for OK, -1 for invalid).
286 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
287 MARC output rather than returning "new" buffer.
289 yaz-client warns about unknown init options.
291 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
295 Added support for SRW sort in Generic Frontend Server. Patch
296 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
297 sortKeys - or NULL if none is provided.
299 Fixed bug #307: It was impossible to specify indefinite/no timeout
300 for ZOOM_event. Special timeout value -1 now means indefinite timeout
303 Added support for multiple languages and charsets to be specified in
304 ZOOM. Each charset/language is separated by a blank. If negotiation is
305 in effect in init-response, Option
306 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
307 Code based on patch by Vasiliy Osadchuk.
309 Fixed bug #306: infinite recursion that occurred when calling
310 yaz_log_level_init as the first call (before other log level or
313 Fixed bug in scan handling in front end server: if preferred-Position-In-
314 Response was non-present, a NULL pointer referece was performed.
318 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
319 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
320 now defined for all those error codes. So instead of putting 109 in
321 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
322 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
324 Modified the yaz-marcdump utility to skip garbage bytes between MARC
327 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
329 Program yaz-client now exits and produces an error message if multiple
330 Z39.50 servers are specified on the command line (none or one allowed
333 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
338 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
340 Fixed bug #272: Preserve spacing for CCL terms.
344 Added support for virtual hosts and multiple backend servers for
345 the YAZ frontend server. The configution is XML based and
346 support specificition of CQL to RPN mappings and explain information.
347 See section "Virtual Hosts" in the YAZ manual.
349 Extended OPAC display utility. OPAC display utility renders
350 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
351 to supplement yaz_marc_decode_wrbuf.
353 Fixed a bug in MARC decoder that could caused it to crash for some
354 invalid MARC records. More diagnostics and warnings where added in
355 XML output (warnings, etc are stored in comments).
357 --- 2.0.34 2005/02/08
359 Fixes for UNIX domain sockets. Bug #261.
361 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
363 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
364 Added yaz_marc_subfield_str which defines subfield lead string which is
365 used in YAZ_MARC_LINE format. Default string is blank+$. Added
366 yaz_marc_endline_str which defines end of fields string used in
367 YAZ_MARC_LINE format. Default string is newline.
369 Experimental support for MarcXChange. This format can be produced
370 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
371 http://www.bs.dk/standards/MarcXchange.xsd
373 Added yaz-client commands scansize that sets maximum number of
374 entries to be returned by scan.
376 --- 2.0.32 2005/01/11
378 Added support for SRW scan in yaz-client and Generic Frontend Server.
380 * Added whereInList member to SRW Scan Term.
382 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
384 Fixed NMEM system to return aligned blocks on the smallest boundaries
385 that are suitably aligned for all possible types on the particular
386 architecture YAZ is being built for.
388 --- 2.0.30 2005/01/04
390 Fixed numerious warnings that was issued with newer versions of GCC.
392 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
393 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
396 Make YAZ Generic Frontend Server slightly faster.
398 Enhance (and reduce) logging for Generic Frontend Server.
400 Revert YAZ log system so that it flushes every write operation
401 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
403 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
404 instead of LOG_, due to name clash with syslog(3). LOG_ are still
405 present. New applications should define YAZ_USE_NEW_LOG=1 - this
406 will effectively disable old definitions.
408 --- 2.0.28 2004/11/09
410 Added yaz_log_time_format which specifies log format using
413 Added yaz_log_module_level which returns mask for a module. Value
414 is non-zero mask a if module is enabled; zero if disabled.
416 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
417 in include/yaz/cql.h.
419 Fixed bug #176: Dont throw diagnostics on empty SRU args.
421 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
423 Fixed bug #172: RPM builds does not enable SSL.
425 Doxyfile.in part of dist. Doxyfile generated by configure.
427 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
428 are given and the corresponding component does not exist.
430 Extend CCL documentation in YAZ reference. Describe r=r.
432 --- 2.0.26 2004/10/01
434 Fixed MARC->MARCXML conversion to properly deal with
435 fields, subfields, indicators having non-ASCII characters.
437 Fixed MARC->MARCXML conversion so that ASCII control characters
438 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
441 Added YAZ GFS support for conversion from Z39.50 surrogate
442 diagnostics to SRW surrogate diagnostics.
444 Bug fix: YAZ GFS did not return schema in explainResponse.
446 --- 2.0.25 2004/09/30
448 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
449 now converts recordSchema to elementSetName as well as schema URI.
451 Fixed bug in COMSTACK that prevented HTTP request packages from being
454 --- 2.0.24 2004/09/29
456 Added CCL facility r=r "range" which is similar to r=o "ordered" but
457 does not require white-space before and after the dash in a range, e.g.
458 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
461 Fixed a few AC_TRY_LINK configure tests that did not operate properly
462 due to new GCC removing "redundant" code.
464 Added yaz-client commands scanpos and scanstep that sets preferred
465 position and step-size for scan.
467 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
469 Added CCL utility ccl_qual_buf which parses one or more CCL
470 spec lines in a buffer.
472 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
473 of name and value - ignoring empty lines and comments.
475 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
477 Added odr_get_element_path which returns current element path for an
478 ODR handle. This utility is useful in error handling or user-defined
481 Added ODR_PRINT utility odr_set_stream which is is a more generic
482 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
483 to a write function and pointer to close function. The close function - if
484 non-NULL - will be called during odr_destroy.
486 Fixed bug in CCL parser where truncation char was not removed from
487 right side when truncation=both was in effect.
489 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
492 --- 2.0.23 2004/08/11
494 Fix buffer overrun in CQL parser when dealing with proximity (%).
496 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
497 to UTF-8/UCS conversion is now only based on codetables.xml.
499 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
501 --- 2.0.22 2004/08/06
503 Add support for more "commit changes" in ZOOM (uses Extended Services).
505 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
508 Yet another small fix for configure of SSL.
510 --- 2.0.21 2004/05/14
512 Fix SSL libs for configure when --with-openssl=DIR is given.
514 --- 2.0.20 2004/05/10
516 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
518 SSL comstack now uses yaz.pem certificate file on server side
519 by default. Certificate filename can be configured by calling
520 comstack function cs_set_ssl_certificate_file before cs_bind is used.
522 Fix bug regarding multiple calls to ZOOM_connection_connect.
524 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
526 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
527 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
529 ZOOM now allows inspection of X509 peer certificate for verification.
530 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
532 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
533 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
534 as "modular" but it simplifies things.
536 Added cs_get_peer_certificate to that returns peer X509 PEM.
538 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
539 NULL if SSL is unavailable.
541 Documentation about MARC decoding tools.
543 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
545 --- 2.0.19 2004/03/30
547 Rename CHANGELOG to NEWS to follow GNU style packing.
549 Fix bug with missing initialization of member in init_diagnostics.
550 This bug affects threaded version of GFS server.
552 --- 2.0.18 2004/03/20
554 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
557 Ensure zlib.dll is packed with Windows install.
559 --- 2.0.17 2004/03/17
561 Fix encoding of xsd:string to use text instead of CDATA.
563 Fix endless loop in CQL parser with unbalanced ".
565 Use a more compact way to store MARC-8 conversion tables.
567 --- 2.0.16 2004/03/16 Debian only
569 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
572 Update CQL parser to use new CQL 1.1 modifiers for booleans and
577 --- 2.0.15 2004/03/01
579 Another fix for decoding of XML packed records.
581 --- 2.0.14 2004/02/25
583 Fixes for Chunked encoding. White space not ignored after length spec.
585 Update NS and use default NS for SRW diagnostic elements.
587 --- 2.0.13 2004/02/23
589 Implement ZOOM_resultset_cache_reset which resets record cache.
591 Implement ZOOM_resultset_sort which sorts a result set.
593 Implement chunked HTTP transfer.
595 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
597 --- 2.0.12 2004/02/16
599 Added member 'schema' to bend_explain_rr structure so that backend
600 can specify explain record identifier. Defaults to Zeerex 2.0.
602 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
604 --- 2.0.11 2004/02/16
606 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
609 Added init command for yaz-client which sends "extra" init request.
611 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
612 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
614 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
616 Make ZOOM error code for "invalid query".
618 Fixed compilation for SSL which wasn't properly enabled for all platforms.
620 --- 2.0.10 2004/02/05
622 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
625 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
627 Added option -p <file> to make Generic Frontend Server to write PID file.
629 Added option -D to put Generic Frontend Server in background on its own.
631 Make ZOOM C recognize option "password". If unset, "pass" is used
632 (for backwards compatibility).
634 Fixed a bug in Generic Frontend Server that could make it crash if a
635 client sets characterSetNegotation bit, but didn't pass negotiation stuff
638 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
639 Must be issued before open, in order to be in effect.
641 --- 2.0.9-6 2004/01/12 Debian/Windows
643 Make the SRU server more picky WRT unknown params, etc.
645 Bug fix: ZOOM scan response didn't return displayTerm - when present.
647 New YAZ client command, options, that sets Z39.50 options.
649 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
650 options from a string of tokens (one token for each option bit).
652 Update SRW diagnostic code messages.
654 --- 2.0.9-5 2004/01/07 Debian/Windows
656 Handle user defined stylesheet for SRW/SRU.
658 --- 2.0.9-4 2004/01/06 Debian/Windows
660 Fix bug in decoding of Content-Length.
662 --- 2.0.9-3 2004/01/06 Debian/Windows
664 Fix a bug with decoding of XML packed records.
666 --- 2.0.9-2 2004/01/05 Debian only
668 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
670 Fix bug in SRW/SRU diagnostics decoding.
674 Fixed bug in Generic Frontend Server which could drop records exceeding
675 preferred message size. Reported and fixed by Irina Dijour.
677 Fixed calculation of package size for structured records in Generic
678 Frontend Server. Reported and fixed by Irina Dijour.
680 Fixed namespace for SRW/SRU diagnostics.
682 Fixed SEGV in yaz-client that occured for HTTP connection errors.
686 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
687 this version is incompatible with version 1.0 and older YAZ SRW/SRU
690 CQL changes to reflect recent changes to the specification:
691 * Documentation talks about context sets instead of index sets.
692 * Documentation talks about indexes instead of qualifiers.
693 * The CQL-to-PQF transformer's configuration file now uses
694 "index.set.name = <attributes>" instead of the old form
695 "qualifier.set.name = <attributes>". (Both forms are still
696 understood but the latter is deprecated.)
697 * CQL terms with no explicit index specified are now interpreted as
698 cql.serverChoice instead of srw.serverChoice (which of course
699 behaves exactly the same.)
703 MARC conversion can now generate ISO2709 output in another
704 character set. yaz-marcdump uses this facility if you invoke it
707 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
708 functions from there can be used from C++.
712 Frontend server now transfers memory from decoded packages to stream
715 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
716 references to show up.
718 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
719 the ZOOM Abstract API. The older names for the same options are still
720 also supported for the benefit of old applications.
722 ZOOM-C supports "implementationId" and "implementationVersion" options
723 to go along with "implementationName". These allow the user code to
724 specify identification strings to be sent to servers.
725 Add OID for the new ExtLite attribute set.
727 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
728 as requested/supplid by Ere Maijala <ere@atp.fi>
730 For generic frontend server, reverse the order of
731 "toolkit-supplied / application-supplied" strings sent as implementationId,
732 Name and Version. Also, remove the spaces around the slash. This brings
733 the GFS in line with the behaviour of ZOOM-C on the client side.
735 Add function ZOOM_scanset_display_term.
737 yaz-client shows scan displayTerm if present.
739 Utility yaz-iconv is now installed by default along with the man page
742 Extend configure check for OpenSSL to use pkg-config where available (such
745 Incorporate patch by Morten Bogeskov which allows a Unix file socket
746 server to specify uid/gid/mask for socket using the format
747 unix:[user=uid,][group=gid,][umask=mask,]file=path
748 If file= is omitted the existing format is assumed, e.g.
750 in which case the mask is 0666 (rw for everybody).
752 Major restructure of YAZ source. All source in libyaz is in src directory.
753 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
754 util (utility programs such as ASN.1 compiler, yaz-marcdump).
756 Added man page for utility yaz-marcdump (used to be called marcdump).
757 yaz-marcdump is installed by 'make install'.
759 Fixed a memory leak in Generic Frontend Server that occurred when decoding
760 of incoming package failed.
762 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
764 Change prototype of odr_perror: add const to message string.
766 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
768 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
769 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
770 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
771 DNS lookup. There should not be any compatibility problems with this
772 assuming that blocking=1 or 0 is used.
774 Fix bad reference in UNIX comstack in function cs_addrstr.
776 Fix for compilation on AIX.
778 The generic front-end server (server/seshigh.c) now supports returning
779 Init diagnostics to the client in User-information-field, in
780 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
785 Allow any CQL relation (not just all,any,exact,scr).
787 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
788 that features the same UI.
790 Implemented command update0 in YAZ client which is equivalent to
791 update but uses old of Ext Update ASN.1.
793 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
794 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
795 Previously no OID was used for this info.
797 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
798 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
799 returns 'malformed search term' otherwise.
801 SortResponse member resultCount now set to NULL in sort handler of
804 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
807 Add three new utility functions for translating OIDs between various
808 formats -- symbolic name such as "Usmarc", minus-1-terminated int
809 arrays and dotted strings such as "1.2.840.10003.9.5.1":
810 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
811 char *oid_to_dotstring(const int *oid, char *oidbuf);
812 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
814 Reverted modifications for ES Update definition for z_IU0Update
815 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
816 is back to YAZ 2.0.2.
818 String value attributes for CCL parser.
820 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
821 which their FirstSearch server returns in Init responses, sometimes
822 carrying useful diagnostic information when Init fails. This has the
823 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
824 "z39.50/oclcui.asn", where its definition is somewhat different from
825 what OCLC document on their web-site, as required to interoperate with
828 Support for anonymous authentication in yaz-client. Use the command
831 * Fix the OID of the Index Data-local "admin" Extended Service from
832 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
833 the 1000, which indicates a locally-defined OID, was a mistake.
837 Fix CCL directive @case handling so that it affects string match for
838 both CCL keywords and qualifiers.
840 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
841 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
842 Decoder has been updated with ASN.1 changes as listed in
843 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
844 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
845 z_IUUpdate, remains unchanged.
847 ZOOM_record_get may now return a record in a specific character set.
848 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
849 "from" is the character set of record as returned by target. "to" is
850 the character set to be returned. If omitted, "to" is UTF-8.
852 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
854 New ODR utility, odr_getelement, which returns name of element for
855 which encoding/decoding failed.
857 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
858 in cases where a required element was omitted.
860 Bug fix: some MARC8 sequences were not converted.
862 New ZOOM option "step" which specifies number of records to be
863 retrieved in one chunk. Used in conjunction with "start" and "count".
865 SRW support for yaz-client. Use scheme http: to use it, e.g.
868 yaz-client no longer does (un)intelligent character set conversions
869 by default. Can be enabled with charset and marc_charset commands.
871 xmalloc trace fix for 64-bit systems such as DEC alpha.
873 Solaris 2.6 compile fix.
875 New function, cql_strerror() translates SRW error codes, as returned
876 by cql_transform_error(), into human-readable English strings. Used
877 in yaz-client diagnostics when appropriate.
879 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
880 converts it into a type-1 query which is sent to the server. This
881 makes CQL available for use with all Z-servers, as opposed to the tiny
882 minority that can handle CQL queries themselves.
886 New Debian package layout similar to the Redhat Package layout.
888 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
889 and search result respectively.
893 Redhat package is now several packages: libyaz (runtime libraries),
894 libyaz-devel (development and documentation, and yaz (utility programs).
895 Package spec file by Morten Bøgeskov.
897 New member 'schema' in struct bend_fetch_rr which the name of requested
898 schema (SRW/SRU) for record (or NULL if none was given). The fetch
899 handler MAY set this to reflect the schema of the returned record.
901 New member 'display_term' in struct scan_entry. GFS now sets member entries
902 and allocates scan entries to be filled by user scan handler. In previous
903 version, entries member was allocated by the scan handler. That still works,
904 but the GFS will ignore member display_term - assuming it was NOT set by
905 the handler. The fact that the GFS now allocates the entries both allows
906 for new members and makes a scan handler easier to write.
908 Fix CQL lex buffer overflow.
910 SRW/SRU recordPacking. For SRW default recordPacking is string. For
911 SRU default recordPacking is string.
913 SRU protocol support for frontend server.
915 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
917 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
919 Added scan for the ZOOM shell (zoomsh).
923 * String Identifers for Schemas (Amendment 5).
924 http://lcweb.loc.gov/z3950/agency/amend/am5.html
925 Old definition for schema
926 Odr_oid *schema; /* OPT */
931 Z_InternationalString *uri;
932 #define Z_Schema_oid 1
933 #define Z_Schema_uri 2
936 * resultCount parameter to Sort Response (Amendment 1).
937 http://lcweb.loc.gov/z3950/agency/amend/am1.html
939 Support for SRW 1.0 over HTTP. This is an optional feature and
940 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
943 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
944 on the same port. SRW SearchRetrieveRequests are mapped
945 to bend_init,bend_search,bend_fetch,bend_close.
947 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
949 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
950 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
952 ZOOM connections are SRW based if schem http is used for hostname
953 in connect, e.g. z = ZOOM_connection_new("http://myserver");
954 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
956 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
957 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
958 distance=n, order=true/false, relation=le, prox unit=word. If
959 n is omitted, distance 1 is used.
961 Fixed problem with C compiler include path in wrong order.
963 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
964 on Solaris. Patch from Ko van der Sloot.
966 New MARC decode API. All new functions operate on a yaz_marc_t
967 handle. The most important new functions are: yaz_marc_create,
968 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
969 decode and destroy respectively. Decoder can produce formats
970 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
971 include/yaz/marcdisp.h.
973 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
974 to UTF-8, UCS-32, wchar_t or Latin-1.
976 * Prototypes for yaz_iconv_-functions moved to separate header
977 include/yaz/yaz-iconv.h.
979 Make a few private functions 'static' in unix.c. This prevents
980 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
982 For ZOOM connection, the options targetImplementation{Id,Name,Version}
983 are set when Init Response is received.
985 New function ZOOM_connection_error_x similar to ZOOM_connection_error
986 but returns diagnostic set as well.
988 New function yaz_strerror which is a portable wrapper for
989 strerror/strerror_r/GetLastMessage.
991 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
992 is returned for MARC. If type is "oai", then OAI MARC is returned.
994 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
999 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1001 Fix bad race conditions on SIGTERM and terminate gracefully in
1004 Move retrieval (data1) module to Zebra since nobody seems to be
1007 Add GRS-1 render for ZOOM using same format as yaz-client.
1009 --- 1.9.1 2002/10/05
1011 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1013 Fix broken ESpec handling in data1 module.
1015 SGML reader parses comments and makes them part of the data1 tree.
1017 Added several type casts so that YAZ compiles as C++ code.
1019 ZOOM didn't handle PDU encoding failures properly.
1021 Added more Bib-1 diagnostics (approved extensions).
1023 GNU configure: better check for iconv.
1025 More portable use of accept, getpeername. Check for socklen_t. Use
1026 int/size_t if socklen_t is not defined.
1030 PQF parser rejects bad queries - including those with extra
1031 characters in them. PQF parser used to silently ignore that.
1032 Cleaner API for PQF added, which allows you to get detailed
1033 error information for bad queries (see yaz/pquery.h).
1035 Fixed bug in ZOOM_record_get for type "database".
1037 Implemented mini iconv library supporting conversions between
1038 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1040 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1042 --- 1.8.9 2002/08/20
1044 Fixed ZOOM C record cache so that preferredRecordSyntax and
1045 elementSetName is used to check for already fetched records.
1047 --- 1.8.8 2002/08/02
1049 Added three members in bend_initrequest structure to facilitate
1050 character set negotiation.
1052 Fixed a bug in frontend server that could cause indefinite
1053 loops under rare conditions.
1055 Revised character set utilities (charneg.h) so that encoding
1056 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1058 For PQF, directive @term <type> sets term type for Scan/Search.
1059 Here <type> is general, string, numeric, null. The term type
1060 is inherited - just like @attr.
1062 New call odr_set_charset that sets character set conversion for
1063 international-strings on a ODR stream. Prototype is:
1064 int odr_set_charset(ODR o, const char *to, const char *from);
1065 The InternationalString is still represented as C string in YAZ
1066 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1067 won't). On the protocol level, you can use any encoding.
1069 Support for UNIX sockets in ZOOM.
1071 Solaris recv sometimes returns errno == ENOENT. It is treated as
1072 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1074 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1075 both client and server. Code by Morten Bøgeskov.
1077 --- 1.8.7 2002/05/22
1079 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1080 that they can be used directly from Visual Basic. You must recompile
1081 your windows APP if you're using ZOOM.
1083 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1084 Commands "lang" and "charset" sets language and character set respectively.
1085 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1086 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1088 Attributes from multiple CCL fields may be OR'ed rather than merged
1089 using directive "@field or". Fields are still merged by default -
1090 equivalent to "@field merge".
1092 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1095 Fixed bug in zget for parameter ExtendedServicesResponse.
1099 --- 1.8.6 2002/03/25
1101 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1103 Client displays USR.1:SearchResult-1 (hits per term).
1105 Additional Search Info for search in Generic Frontend Server.
1107 Fixed CCL parsing of "field=s".
1109 WIN32 installer - using the excellent NSIS software from nullsoft.
1111 Fixed CCL parsing of "field = - <number>".
1113 Added function yaz_marc_decode that decodes MARC for line mode
1114 display or XML (similar to that used by JZKit).
1116 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1117 Z39.50. But ISO/ILL was, however.
1119 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1120 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1122 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1123 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1125 --- 1.8.5 2002/02/03
1127 New YAZ client features: Command completion and new commands:
1128 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1129 Code provided by Jacob Poulsen.
1131 New call oid_trav, that visits all registered OIDs via callback.
1133 Function ZOOM_record_get now returns const char pointer rather than
1134 void pointer. It saves a lot of type casts.
1136 For YAZ client, command "auth" now allows you to set authentication
1137 in IdPass style. It is enabled when three tokens are given - order
1138 is user, group and password.
1140 Fix memory leaks in MARC record handling for ZOOM.
1142 New option for YAZ client, -k <kilobytes> that sets
1143 maximum record size. Similar to -k option for generic frontend
1144 server and yaz-ztest.
1146 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1148 Prefix query parser reports "fail" when bad attribute set is given.
1150 Fix in MARC decoder. Proximity logging. Fix for attribute set
1151 in scan handler for server. Patches by Shigeru Ishida.
1153 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1156 Configure option --with-openssl=<dir> now works when a directory is
1157 specified. Patch provided by Morten Bøgeskov.
1159 New option for YAZ client, -u <auth>, that sets authentication.
1161 ZOOM fix: error information was sometimes "missing", since error
1162 was cleared/reset too when it shouldn't.
1164 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1166 --- 1.8.4 2002/01/04
1168 Scan for ZOOM API. New object ZOOM_scanset. New functions
1169 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1170 ZOOM_scanset_destroy.
1172 New ZOOM function, ZOOM_connection_last_event, that returns type
1173 of last event (such as "receive data", "send data", "apdu received",
1176 New ZOOM option, schema, that specifies schema for retrieval.
1178 New CCL feature. Qualifiers can be aliases for one or more
1179 other qualifiers (if more than one is given, OR is used).
1181 ZOOM uses named result sets if target supports it.
1183 Two new YAZ client commands: . (dot, which sources a script of YAZ
1184 client commands), and ! (to execute shell command.). Implemented
1187 Working on Debian packages.
1189 --- 1.8.3 2001/11/19
1191 YAZ client enables named result sets only if target supports it.
1193 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1195 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1196 with key="host" to get same result.
1198 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1199 Function Z3950_resultset_record(s) returns references to records
1200 "owned" by resultset. To become owner use Z3950_record_clone.
1202 Function z_ext_record handles Extended Services. Thanks to
1205 --- 1.8.2 2001/11/12
1207 CCL Parser fix: ignore token comma when dealing with and-lists.
1209 Documentation updates for COMSTACK.
1211 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1212 Changed prototype Z3950_records. For some functions, int parameters
1213 were changed to size_t.
1215 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1218 New MARC decode/display function, marc_display_exl, which properly rejects
1219 non-ISO2709 records. YAZ client uses it.
1221 --- 1.8.1 2001/10/29
1223 Fix bug: local attribute set wasn't set correctly in PQF strings.
1227 * Old Z39.50 codecs no longer supported.
1229 Added ZOOM C binding. See http://zoom.z3950.org/
1231 Renamed states for COMSTACKs to avoid confusion with events.
1233 Implemented cs_look and proper cs_rcvconnect.
1235 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1237 Configure detects POSIX threads on OpenBSD.
1239 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1240 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1242 When error is returned from present handler, non-surrogate diagnostic
1243 is returned in present response (and fetch handler is no longer called).
1245 * Minor adjustments to pquery parser (PQF). Token characters may be
1246 escaped by using backslash (C-style).
1248 PQF parser allows string attribute values to be specified. For @attr,
1249 non-numeric characters after the equal-sign are treated as strings
1250 (e.g. @attr 9=title).
1252 CCL trunction character may be defined (@truncation in file)
1254 * function zget_ExtendedServicesRequest sets waitAction to
1255 waitIfPossible (was wait).
1257 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1260 CCL operator names may be set in field definition files (CCL_bibset).
1261 See ccl/bib1 for an example.
1263 Fixes in ASN.1 compiler for C++ compatibility.
1265 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1266 and "op_or" to avoid conflict with C++.
1268 Fixed problem with GNU readline detection on Redhat 7.0.
1270 Added step-size for Scan backend handler.
1272 Fixed bug that made the frontend server crash when no attribute
1273 set was specified for scan.
1275 Front-end server automatically switches to original working directory
1276 when installed as an NT service. Previously -w had to be specified to
1279 Added extended attributes for retrieval module (data1), so that data1
1280 records carry d1_readXML/SGML attributes. d1_read also supports
1281 null-data rules ( <tag/>)
1283 On UNIX when POSIX threads are available, a separate library libyazthread
1284 is created. Programmers should link with that library and the yaz library
1285 when using threads. The reason for the split was that some applications
1286 on Linux, such as Apache, doesn't work well when using shared objects that
1289 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1290 (or any frontend server) in SSL mode by specifying ssl: followed by
1291 address. Only tested on UNIX.
1293 Added feature for CCL module. Virtual structure s=al or s=ol generates
1294 and-list and or-list respectively instead of phrase search.
1298 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1299 log_mask_str. This was done to avoid name conflicts with other libraries
1300 (such as other PHP extensions).
1302 Added raw OID member for preferred record syntax (request_format_raw)
1303 and returned record syntax (output_format_raw) for backend fetch method.
1305 Config file yaz-config now accepts options so that it returns specific
1306 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1308 Shared library support for UNIX using GNU libtool.
1310 * Modified backend interface. Request/Response struct's replaced by
1311 one read/write C struct. For example bend_fetchrequest and
1312 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1313 Every handler - even search has to be registered in bend_init
1314 handler. This means that the YAZ library no longer refers to
1315 external functions and it makes it possible to make the whole
1316 thing a single DLL/SO.
1318 Added Segment handler for backend server.
1320 Added Zmbol/Zebra administrative functions to YAZ client.
1322 Threaded frontend server on UNIX (when POSIX Threads are available).
1323 Starting the server with option -T enables multi-threading.
1327 Added configure option --enable-comp/disable-comp to control use
1328 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1329 located in sub directory asn.
1331 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1332 in ${exec_prefix}/bin along with the other programs yaz-client and
1335 GNU automake used to maintain makefiles.
1337 Added several OID's.
1339 Changed retrieval module so that we can load records with no abstract
1340 syntax defined. Tagpaths in these records are fully composed of string
1343 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1347 On UNIX, the generated makefile now supports a proper 'make install'.
1348 The prefix can be set via GNU configure to set the install location
1349 (default is /usr/local).
1351 * YAZ programs client and ztest were renamed to yaz-client and
1352 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1353 locations, such as /usr/bin,/usr/local/bin,etc.
1355 * YAZ Header files were moved from include to include/yaz. YAZ Header
1356 files are referred to as include <yaz/log.h> rather than <log.h>.
1357 The YAZ include path (-I ..) is therefore the same as before. Programmers
1358 should update their #include statements or use -Ipath/include/yaz
1359 instead. The main motivation for doing this change is that YAZ header files
1360 can be installed in "standard" locations /usr/include,/usr/local/include
1361 without introducing conflicts, since ALL YAZ header files are stored
1362 in subdirectory yaz (under /usr/include for example).
1364 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1365 rather than project/workspace files. We switched because project files
1366 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1369 Changed name of logging function, logf, to yaz_log, to prevent name
1370 clash with some math-log functions. The YAZ header log.h defines logf
1371 to yaz_log (#define) so there should be no incompatibilities by this
1374 Added bend_start/bend_stop handlers for server. These handler are
1375 called on start/stop of server. For windows they are called whenever
1376 a service is started/stopped.
1378 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1379 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1380 in util/yc.tcl. The auto-generated C code structures are, in a few
1381 cases, incompatible with the old decoders. There are differences in the
1382 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1383 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1384 The preprocessor variable ASN_COMPILED is defined when the compiled
1385 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1386 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1387 wish to use the old encoders/decoders you can specify --disable-yc
1390 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1391 version so that it supports both new - and old version of DB Update
1393 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1394 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1395 change. The name parameter can be set to 0 in which no name is specified
1396 for the construction. The macros odr_implicit and odr_explicit sets name
1397 parameter to zero for the construction involved. New macros
1398 odr_implicit_tag and odr_explicit_tag are similar to the others,
1399 except that a name parameter is added. For programmers' that don't use
1400 ODR they probably only need to change the call to z_APDU and z_External.
1402 Added access control facility by interfacing the TCP wrapper library.
1403 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1404 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1405 name of the daemon and enables the access control as specified in
1406 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1408 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1409 den Dool <H.M.vdnDool@kub.nl>.
1411 Added reference ID parameter to most functions in server API - refer
1412 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1414 Changed name of ccl library to libccl.a (was ccl.a).
1416 Fixed bug in decoder for Explain (Category TargetInfo).
1418 Added support for GNU readline in client. Thanks to Jacob Poulsen
1419 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1421 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1422 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1423 IMPLEMENTATION! This change was made to the development version before
1424 the ZIG decided to retract the amendment. If any users MUST be
1425 compatible with the original Update definition, PLEASE CONTACT US, and
1426 we will include a separate definition corresponding to the old Update
1427 ES. Note that because of the change to the ASN.1 of the
1428 TaskPackageRecordStructure we cannot define a single structure that
1429 will support both versions.
1431 * Added const modifier to buffer parameter for some ODR/BER encoding
1432 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1433 completeWAIS, odr_dumpBER.
1435 Fixed bug in client.c which caused a crash when a scanResponse didn't
1436 contain positionOfTerm.
1438 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1439 * will cause an error in a client if a non-YAZ target sends both a
1440 * list of Scan entries and non-surrogate diagnostics.
1442 Retrieval module enhancements. Tag sets may be typed in the reference
1443 to it. From the .abs-file the "tagset" directive takes a third optional
1444 integer type for the tag set referenced. From a .tag-file the "include"
1445 directive takes a third optional type as well. The old "type" directive
1446 in the tag set itself is still recognized but acts as the default type
1449 Backend interface change. Individual Scan terms returned from bend_scan
1450 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1451 in include/backend.h.
1453 Retrieval module enhancements. Multiple tag sets and attribute sets may
1454 be specified in abstract syntax specs. Revised the error/warning for
1455 logging messages reported by the retrieval module when reading the
1458 Object Identifier system (oid_..) changed. The API is backwards
1459 compatible but the oid-routines now allocates new OID's when needed.
1460 Raw OID's may be specified in oid_getvalbyname.
1462 YAZ now uses GNU configure to generate Makefile(s).
1464 * Minor changes in some of the member names of DeleteResultSetRequest and
1465 DeleteResultSetResponse. See include/proto.h.
1467 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1468 and added member 'languages' in TargetInfo (which was missing).
1470 Changed the way attribute sets are handled in the retrieval
1471 module. These are now cached, just like the abstract syntaxes
1474 Changed YAZ so that it links with compiled ASN.1.
1476 Added Explain-schema definitions and mapping routines. The following
1477 Explain categories have been implemented: AttributeDetails,
1478 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1480 Fixed minor bug in Windows version of Server Library.
1482 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1484 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1486 Added EXTERNAL: UNIverse Resource Report (non-standard).
1488 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1489 ENUMERATED and SET OF.
1491 * Added 'const' to some of the char pointer arguments for the
1492 functions, data1_read_node, data1_getelementbytagname,
1493 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1496 Fixed bug in data1_insert_taggeddata - the last_child member of
1497 parent wasn't initialised.
1499 * Changed data1_read_record and data1_read_node so that the supplied
1500 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1501 doesn't refer to any parts of the "SGML"-buffer.
1503 Fixed bug in server library (Windows version of statserv_remove).
1505 * Changed code so that it compiles as C++. The type definition
1506 of Odr_fun which is a member of Odr_arm was changed. The result is,
1507 that an explicit typecast is needed for the fun pointer when
1508 using Odr_arm - as in:
1509 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1511 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1513 Implemented the new structured date and time definition as approved
1514 by the ZIG. Added schemaId element to the specificTag in Espec-1
1515 (also approved at the last ZIG). Thanks to RVDM.
1517 Added some Object identifiers (RVDM).
1519 Changed the Update Extended Service (RVDM).
1521 Added command "refid" to client which specifies referenceId for
1522 the following requests.
1524 Implemented extended service handling for server. See ztest.c
1525 for an example as well as backend.h. New handlers are registerd
1526 in the Init handler.
1528 * Changed interface for sort in server.
1530 Added new members to statserv_options_block. It allows a server
1531 to read options from another source than just the command line. Thanks
1532 to Charles Woodfield.
1534 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1535 renamed to zboolean. Some C++ compilers complained about the name.
1537 Minor changes to gils.abs. Added index 's' (sort) on title
1538 and date/time-last-modified.
1540 --- 1.4pl2 1998/1/30
1542 Fixed bug in server library regarding inetd mode (-i). This bug
1543 was introduced by release 1.4.
1545 --- 1.4pl1 1998/1/29
1547 Added sort facility in client and backend server interface.
1549 Fixed problem with dependencies in Makefile(s).
1551 Fixed bugs for encoders/decoders of extended services and
1554 Implemented sub-tree feature for schemas. Sub-trees are
1555 referenced in *.abs-files. See explain.abs for an example
1556 of the use of this feature.
1558 Modified bib1.att; local attributes for ANY didn't include
1559 ANY itself (only affects use of the retrieval module).
1561 Fixed bug in plain SGML reader in function data1_read_node:
1562 tags with prefix "var" was incorrectly interpreted as variants.
1564 Added feature "sub-schemas" to enable references to - and definitions
1565 of - group of elements.
1567 * Removed member parent from type data1_element (in data1.h).
1569 Implemented function odr_nullval() that returns the value of
1572 * Removed member num_children from data1_node (in data1.h).
1574 Made NT service interface part of the server library. The
1575 function statserv_main uses the NT service when required and
1576 calls the statserv_start / statserv_close routines.
1578 Routine zget_SearchRequest and zget_PresentRequest fills
1579 resultSetName/Id member with "default" instead of "Default".
1581 Fixed memory leak in server. Request queue member wasn't freed.
1583 Fixed nmem_exit so that memory is freed.
1587 Revised the CCL parser utility to be thread safe.
1589 Added function, oid_ent_to_oid, to replace the function
1590 oid_getoidbyent, which is not thread safe.
1592 * Added nmem_init and nmem_exit to initialize and release
1593 NMEM resources. Function nmem_init should be called once in the
1594 initial thread before NMEM/ODR is used. statserv.c and client.c
1595 have been changed accordingly. The change was necessary to make
1596 NMEM thread safe. The NMEM memory pool is shared amongst threads
1597 in a process. Unix-based applications will still work fine without
1600 Added NT Services interface for the the Z39.50 (statserv) Server.
1601 Refer to the ztest.c source on the usage.
1603 Windows 95/NT port using MSVC5.0. Project files are included in the
1606 * Defined new 'global' handle for the retrieval (data1) system. The
1607 new handled, data1_handle, describes the state of the data1 system.
1608 This handle is passed as first argument to virtually all
1609 data1 related routines. The functions data1_create and data1_destroy
1610 creates and destroys a data1 handle respectively.
1612 Added ODR encode stream member to all backend request structures
1613 init, search, scan etc. This stream should be used to allocate all
1614 memory used for the response when thread safe operation is needed.
1616 Changed the comstack utility, cs_addstr, to be thread safe. The
1617 returned hostname string returned by the function is now part the
1620 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1621 function. The cs_straddr takes a COMSTACK handle as argument, so this
1622 function must be used after cs_create and before bind/connect.
1623 This function is thread safe.
1625 Moved test server to 'ztest' directory - generic server code still
1626 in 'server' directory.
1628 Made prefix query (pquery.c) utility thread safe.
1630 Added new function modifier YAZ_EXPORT to 'export' public DLL
1631 functions when using windows (see include/yconfig.h).
1633 Added definitions to the OID database (util/oid.c) (RVDM).
1635 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1637 Added call to ccl_rpn_delete in client program.
1639 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1640 release of RPN structure.
1642 Added support for C++, headers uses extern "C" for public definitions.
1643 With input from RVDM.
1645 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1646 Thanks to Ronald van der Meer (RVDM).
1648 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1650 Added support for private extensions to the OID database
1651 (oid_setprivateoids()). Thanks to RVDM.
1653 Added optional, physical ANY (key replication)
1655 Fixed null-reference problem in GRS-1 output filter.
1657 Proximity operator added to Prefix Query Format (PQF).
1659 In test client command "base" accepts multiple databases.
1661 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1665 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1667 Smallish bug-fixes in the new encoders/decoders (explain).
1669 Bug fixed in DeleteRequest.
1671 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1673 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1675 Added SOIF syntax (using private OID for now) to retrieval module and client.
1677 Added Update extended service.
1679 Added SearchResult-1 additional info structure.
1681 Added optional CCL (ISO8777) interpreter as separate module. Available
1684 --- 1.2 1996/6/10 (1st anniversary release)
1686 Added Summary record syntax. Lightly tested.
1688 Added OPAC record syntax. Untested.
1690 Added ResourceReport service encoders/decoders. Untested.
1692 Fixed bug in z_Unit - wrong tagging on unitSystem.
1694 Fixed bug in the DiagRecs decoder.
1696 Added options for max PDU size and session timeout to frontend-server.
1698 Added documentation of query-language parsers and other supporting utilities.
1700 [frontend-server] Added Attribute set to the bend_scanrequest API.
1702 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1703 surrogate diagnostics were generated.
1705 [retrieval] Allow multiple local values for attribute.
1707 [retrieval] Allow multiple attributes per element in .abs files. index type.
1709 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1711 --- 1.1pl2 1996/4/10
1713 Minor changes, mostly specific to Zebra's requirements (retrieval)
1717 Repaired bug in frontend server when running multiple listening
1718 endpoints in dynamic mode.
1720 z_External() now won't break if a known, ASN.1 value comes encapsulated
1721 in an octet-string. The value will pass through unmodified in an Odr_oct.
1723 Added a bit of code to the demo client to decode & display
1724 ASN.1-structured records represented in the octet-aligned branch of
1725 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1727 Added z_ext_getentbyref() to the ASN module. Doc updated.
1729 * Completed the SCAN definition in the ASN module. This may break SCAN
1730 code based on older YAZ-versions at compile-time. The fix is easy -
1733 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1734 under the SCAN definition. Remember to initialize this, server-people.
1736 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1737 that this does not extend to ODR and ASN.
1739 Comstack allows insertion of established socket (primarily for
1740 inetd-operation of servers). Doc updated.
1742 Front-end server can now start from the inetd in TCP mode. Doc
1745 --- 1.0pl4 1996/1/24
1749 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1750 the rank and record number.
1752 Adjustments to the frontend server.
1754 Fixed diagnostic BER dumper. It ignored the file argument.
1758 Various changes to retrieval module.
1760 Changed the union discriminators of the protocol files from enums to
1761 ints paired with #defines.
1763 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1766 *Changed operator in the RPN structure to 'roperator', again to avoid a
1769 Fixed problems in Explain decoders/encoders.
1771 --- 1.0pl2 1995/12/6
1773 Memory bug in log module fixed.
1775 --- 1.0pl1 1995/12/5
1777 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1779 Bug in Explain DatabaseInfo module fixed.
1781 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1785 The shift to v1.0 signals that we now consider the *core* functionality
1786 of YAZ reasonably stable (the core being more or less equivalent to
1787 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1788 tested (Explain not at all - though that will happen soonish).
1790 Minor changes to code to support Windows port.
1792 Various minor changes after we're getting to use GRS-1 & co. more.
1794 Added Espec-1 format.
1796 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1797 of the protocol and it cannot be selected when encoding (maps into 'string'
1798 when decoding). Needed to talk to some servers.
1800 Demo client can request simple element set names.
1802 Added Diagnostic Format encoders/decoders.
1804 Added simple Close handling to frontend server (no hooks for resource
1805 reporting yet), and demonstration client.
1807 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1809 --- 1.0b3 1995/08/24
1811 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1812 handled incorrectly when records were requested in the searchResponse. This
1813 will only affect you if you use the frontend-server.
1815 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1816 Test-client will ask for and print GRS1. Ztest will return dummy records
1819 Added Explain encoders/decoders to the service-level API. Untested.
1821 Added Extended Services: Item Order encoders and decoders to the Service-
1822 level API. Untested. We could use a recent copy of the pertinent bits
1823 of the ILL protocol to add those bits.
1825 Added diagnostic format 1 encoders/decoders to the service-level API.
1828 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1829 odr_cons.c, which causes a more correct output.
1831 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1832 was always set to 0 when no records were requested in the searchRequest.
1834 * Added better external-handling. This shouldn't harm old code that
1835 *encodes* externals. It can break code that looks for a
1836 'single-ASN1-type' representation, since those types that are known
1837 are now decoded immediately. Look at the SUTRS sample code in
1838 seshigh.c and client.c. Documentation updated.
1840 Handling of structured records in bend_fetchresponse. Length -1 marks
1841 structured record, type is deduced from format field.
1843 --- 1.0b2 1995/06/27
1844 Fairly quick maintenance release to add SUTRS support.
1846 Fixed handling of SUTRS records in the demonstration client.
1848 * Added format field to the bend_fetchrequest and bend_fetchresponce
1849 structures of the backend API (frontend server). When the record is
1850 returned, the value of the format field is mapped to an OID. The
1851 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1852 of the record. The special value VAL_NONE in the bend_request means
1853 that no specific format was requested by the client. Documentation
1854 updated accordingly. Test server (ztest) will return a fixed dummy
1855 SUTRS record if your client requests SUTRS.
1857 Documentation updated accordingly.
1859 You can now set external libraries and RANLIB support in the top-level
1863 First public release.
