1 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2 the following new functions:
4 ZOOM_connection_get_{socket,mask,timeout},
5 ZOOM_connection_fire_event_{timeout,socket}.
6 The existing blocking event handler, ZOOM_event, is a wrapper for the
7 + blocking ZOOM_event_sys_{poll,select}.
9 Implemented function ccl_xml_config which parses XML version of CCL
10 configuration (bug #798).
12 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
14 Added timings utility (yaz/timing.h)
18 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
21 Fixed bug #779: Rotation of apdu.log fails.
23 Fixed for character set conversions:
24 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
25 Honor G1 set in MARC-8 decoding.
29 Fixed bug #775: char conversion does not handle Alternative UTF-8
32 Implemented function yaz_marc_read_line which parses MARC line format
33 records. There is a wealth of formats out there. So far, this function
34 reads line records produced by yaz_marc_write_line.
36 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
37 more generic and easier to remember(!) options: -i format and -o format
38 which specifies input format and output format respectively - where
39 format is one of "marc", "marcxml", "line", "marcxchange".
41 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
42 does not print anything except warnings for records.
44 For yaz-marcdump, added support for MARC split into files (-s) with a given
47 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
48 spec, at http://www.loc.gov/standards/sru/record-update/
49 This has changed the binary layout of the following structs:
50 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
51 bend_update_rr . Patch by Ko van der Sloot.
53 Added GFS utility function bend_assoc_is_alive which returns 1 if
54 association is still alive (client is connected); 0 otherwise (client
55 closed connection). This allows busy servers to stop working for
58 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
59 been a separate piece of software. This version of ziffy has been modified
60 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
62 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
64 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
65 Client code may now interrogate options such as "init_opt_sort" to
66 find out whether the server claims to support various options.
70 Added utilities yaz_{set,get}_esn to set/get element set name from
73 Removed the build of libyazthread.la. The libyaz.so is the threaded version
74 of YAZ and has been so since YAZ 2.1.10.
76 Implemented ZOOM_record_error which returns error information for
77 record (surrogate diagnostic).
81 Updates for SRU Update by Ko van der Sloot:
82 1. Changed name from "operation" to "action"
83 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
84 versions in the code, marked as 'backward compatible'.
85 3. Added diagnostics for SRU Update.
87 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
89 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
91 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
93 For GFS, fixed problem with SRU diagnostic 'First record position out of
94 range' being issued for 0 hits.
96 zoomtst10 part of Windows Build.
100 Implemented yaz_filepath_comp which splits a path into file path
101 components (required by Zebra 2.0.3+).
103 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
104 BSD inspired license until now so this should not have any real impact on
105 anybody. See http://www.opensource.org/licenses/bsd-license.php
107 Fixed bug #687: Missing log lines.
109 Fixed bug #678: CQL to PQF translation does not preserve double-quote
112 Fixed bug #689: SRU diagnostics to be added.
114 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
115 whether a connection is idle (no more work do do).
117 --- 2.1.34 2006/10/04
119 Change type of optval from long to int for invocation of setsockopt with
120 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
122 Added support for specifying the max log file size for the Generic
123 Frontend Server. The size is given with option -r.
125 --- 2.1.32 2006/09/21
127 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
129 --- 2.1.30 2006/09/17
131 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
134 Fixed bug in Generic Frontend Server that could cause a server to stop
135 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
137 For the generic frontend server, the maximum record size is used as maximum
138 size of incoming packages (SRU + Z39.50). The value until was previously
139 only used in Z39.50 Init negotiation and, later, in a session controlled
140 sizes of records returned. This is controlled using -k option. It can be
141 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
143 --- 2.1.28 2006/09/04
145 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
148 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
150 New option for yaz-marcdump -lpos=value which allows setting a portion
151 of MARC header to a certain value.
153 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
155 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
156 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
158 --- 2.1.26 2006/08/15
160 Fixed problem with SRU mode type (soap, get, post) for yaz-client
163 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
165 --- 2.1.24 2006/08/08
167 Fixed MARC ISO2709 encoding routines to deal with character set
170 Minor changes to GFS logging. Database included in search request log
173 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
174 cached/multiple records.
176 Shared libraries are built by default on Unix+configure.
178 Changed cql2pqf transformation to use a different evaluation order. The
179 new order is: always, relation, structure, position, truncation, index
180 and relationModifier. Old order was: always, relation, relationModifier,
181 structure, index, position, truncation. Note that the the latter ones
182 override former ones for identical attributes.. The new scheme means that
183 it is possible to override any existing attribute with a relationModifier.
184 And also that it is possible to override everything for the index rule
185 (except the ones listed in relationModifier). No order is perfect but this
186 one, we believe, covers more real cases.. The "always" should have been
187 called "default", since the attributes there can be overridden with all
190 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
191 compilation phase, but also for yaz-config --cflags output. This allows
192 us to have public headers with Libxml2 stuff in them . It should also,
193 eventually, make Libxml2 checks redundant in packages using YAZ, such
196 --- 2.1.22 2006/06/15
198 Changed SRU update structure bend_update_rr so that SRU diagnostics are
199 stored in uri, message and details.. Previously diagnostics were stored
200 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
201 compatibility.. but he's probably the only one affected, so.
203 Added support for CCL, compiled on the client side, in ZOOM-C. This
204 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
205 input; the resulting query objects can be used for for searching with
206 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
208 YAZ' configure searches for OpenSSL by default.
210 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
211 SL_CTX_use_certificate_file. See
212 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
213 for more info. Thanks to Ko van der Sloot.
215 --- 2.1.20 2006/06/02
217 Bug #600: SRU GET, POST support for yaz-client. Introduced
218 command 'sru' which selects method SOAP/GET/POST.
220 Allow missingValueAction to be specified for the sortspec string -
221 function yaz_sort_spec. By default, the missing value action is null.
222 Use ! to specify "abort". Use = followed by stringvalue to specify default
225 Ensured that Present-handler (if defined) is called in GFS before any call to
226 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
227 searchRetrieve requests.
229 Documentation for YAZ is now based on the Docbook XML/XSLT using
230 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
231 is no longer depending on jade/openjade or docbook-to-man scripts.
232 PDF is no longer part of the distribution - but can optionally be
233 made using DSSSL/jadetex or FOP.
235 Added retrieval handling support in Generic Frontend Server to support
236 conversion between MARC/XML as well as XSLTtransforms. See
237 etc/yazgfs.xml for an example.
239 Added Authentication support to Generic Frontend Server in SRU
240 mode. Authentication using HTTP Basic is supported, as is the use
241 of 'x-username' and 'x-password' parameters in the request itself.
243 Added support for a new character set MARC8s identical to MARC8 except
244 that it converts combined characters to single Unicode characters in the
245 Latin-1 range (when possible).
247 --- 2.1.18 2006/04/24
249 ASN.1 compiler 0.4: generates brief Doxygen file header for
250 generated .h/.c files.
252 Utility yaz_iconv now supports conversion to MARC-8.
254 New facilities for the MARC module. The reading - and writing of
255 content are separate methods for the yaz_marc_t handle. The following
256 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
257 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
258 format). Write functions have prefix yaz_marc_write_.. The existing
259 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
260 available. Removed support for OAI-MARC and simplexml (not the
261 simplexml from PHP5).
263 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
264 to be returned for this connection.
266 --- 2.1.16 2006/03/31
268 Allow multiple languages and charsets to be specified with
269 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
270 negcharset iso-8859-1,utf-8
272 Translation of proximity nodes from CQL into PQF now works.
274 Moved to automake 1.8, 1.9.
276 Added function yaz_log_set_handler which allows a log handler to be
277 installed. This handler will be called for all log messages. Output
278 to file is also produced; but that can be disabled by passing NULL
279 fname to yaz_log_init_file.
281 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
283 For SRW (including GFS), accept application/soap+xml as content-type
286 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
287 produces NO stylesheet reference even if a default stylesheet is specified
290 --- 2.1.14 2006/03/14
292 Updated Windows package to include yazd.dll + yazd.lib for the
293 Development component.
295 If the environment variable YAZ_LOG is set, then it is used as a
296 string indicating the default level of logging to use if not
297 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
298 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
299 used as before. So, for example, to omit warnings from YAZ logging,
302 cql_transform() now map structure and other attributes before indexes,
303 so that index-specific structures and other attributes can override
304 defaults. So now a combination of mapping specifications such as:
306 index.dc.date = 1=date-modified 4=5
307 does the right thing.
309 cql_transform() now also respects the "always" mapping specification,
310 which establishes an initial set of attributes to be used for all
311 terms except where overridden by more specific attributes associated
312 with the index, relation or modifier.
314 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
315 which mode to use; one of "post", "get" or "soap" (SRW, default).
317 Fixes for yaz_iconv routines: changed trie-based character set conversions
318 to use only non-negative values for bit fields due to Sun's C compiler not
319 supporting negative values.
321 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
322 sequences where not read correctly. Fix by Rustam Usmanov.
324 Updated win/makefile to use options, settings which makes things
325 compile with VS C 2005.
327 --- 2.1.12 2006/02/01
329 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
331 In ZOOM socket code, use select instead of poll on MacOSX.
333 ZOOM-C now support client-side compilation of CQL into RPN that is
334 sent to the server, enabling CQL to be used against all Z39.50
335 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
336 ZOOM_query object, and submit it using ZOOM_connection_search().
337 The CQL-to-RPN translation uses a configuration file, the name of
338 which must be specified in the Connection's "cqlfile" option.
340 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
341 function, which takes as its start-term parameter a ZOOM_query object
342 (which may have had either CQL or RPN set into it).
345 --- 2.1.10 2005/11/29
347 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
348 GFS to support this as well. Backend handler, bend_srw_update, does the
349 update work. Code contributed by Ko van der Sloot.
351 Allow retrieval of Search Result-1 information in ZOOM by the use of
352 options that are attached to a result set. ZOOM documentation updated
355 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
356 UTF-8 conversion. Patch by Raj Patel.
358 Added option -m to GFS to control formatting of timestamps in log file.
360 Added 'exit' as synonym for 'quit' in yaz-client
362 Added support for specifying SRW resultSetId + resultSetIdleTime in a
363 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
364 for the new members. Patch by Ko van der Sloot.
366 Added support for SRU POST. It is supported for content-type
367 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
369 Do not build the separate Multi-threaded (MT) library libyazthread.la.
370 Instead make the library libyaz.la multi-threaded. Threading as a whole
371 can still be disabled by configure option --disable-threads. Previosly,
372 with older GLIBCs there were problems with MT libs under Apache. This
373 has now been fixed a long time ago.
375 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
378 CQL module modified to be case insensitive for relations/indexes/operations.
380 Fixed bug in CQL transform code: incorrect value relationModifieder
383 Added 'show all' command for yaz-client which retrieves all results
386 Added new yaz-client, xmles, which takes a (private) OID and
387 a document to be sent as an extended service request.
389 Describe new yaz-client commands wait_response and set_auto_wait.
391 Increase TCP/IP listener backlog from 3 (which I am guessing was
392 copied from the SunOS manual entry way back when) so SOMAXCONN, so
393 that the socket will queue as many incoming connections as it's able
394 to handle ongoing connections. In other words, it will never now
395 refuse a connection that it would be able to handle merely because
396 it's not got around to accepting() enough of the pending connections
397 yet. This is the behaviour anyway under Linux, where the listen()
398 argument is ignored; but not under BSD and on systems such as
399 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
400 YAZ-based servers should now be uniform across operating systems in
403 yaz-marcdump uses 64-bit file access on some systems. This is enabled
404 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
405 This allows yaz-marcdump to read large MARC batches (>2 GB).
407 Modified all YAZ source files - except the source which is auto-generated
408 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
411 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
412 corresponding to the existing *_setl() function. These allow option
413 values containing arbitrary valuues.
415 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
416 ZOOM_resultset_sort() in new applications. Its behaviour is identical
417 except that it returns an indicator of whether or not the sort
418 criterion was accepted (0 for OK, -1 for invalid).
422 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
423 MARC output rather than returning "new" buffer.
425 yaz-client warns about unknown init options.
427 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
431 Added support for SRW sort in Generic Frontend Server. Patch
432 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
433 sortKeys - or NULL if none is provided.
435 Fixed bug #307: It was impossible to specify indefinite/no timeout
436 for ZOOM_event. Special timeout value -1 now means indefinite timeout
439 Added support for multiple languages and charsets to be specified in
440 ZOOM. Each charset/language is separated by a blank. If negotiation is
441 in effect in init-response, Option
442 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
443 Code based on patch by Vasiliy Osadchuk.
445 Fixed bug #306: infinite recursion that occurred when calling
446 yaz_log_level_init as the first call (before other log level or
449 Fixed bug in scan handling in front end server: if preferred-Position-In-
450 Response was non-present, a NULL pointer referece was performed.
454 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
455 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
456 now defined for all those error codes. So instead of putting 109 in
457 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
458 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
460 Modified the yaz-marcdump utility to skip garbage bytes between MARC
463 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
465 Program yaz-client now exits and produces an error message if multiple
466 Z39.50 servers are specified on the command line (none or one allowed
469 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
474 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
476 Fixed bug #272: Preserve spacing for CCL terms.
480 Added support for virtual hosts and multiple backend servers for
481 the YAZ frontend server. The configution is XML based and
482 support specificition of CQL to RPN mappings and explain information.
483 See section "Virtual Hosts" in the YAZ manual.
485 Extended OPAC display utility. OPAC display utility renders
486 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
487 to supplement yaz_marc_decode_wrbuf.
489 Fixed a bug in MARC decoder that could caused it to crash for some
490 invalid MARC records. More diagnostics and warnings where added in
491 XML output (warnings, etc are stored in comments).
493 --- 2.0.34 2005/02/08
495 Fixes for UNIX domain sockets. Bug #261.
497 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
499 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
500 Added yaz_marc_subfield_str which defines subfield lead string which is
501 used in YAZ_MARC_LINE format. Default string is blank+$. Added
502 yaz_marc_endline_str which defines end of fields string used in
503 YAZ_MARC_LINE format. Default string is newline.
505 Experimental support for MarcXChange. This format can be produced
506 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
507 http://www.bs.dk/standards/MarcXchange.xsd
509 Added yaz-client commands scansize that sets maximum number of
510 entries to be returned by scan.
512 --- 2.0.32 2005/01/11
514 Added support for SRW scan in yaz-client and Generic Frontend Server.
516 * Added whereInList member to SRW Scan Term.
518 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
520 Fixed NMEM system to return aligned blocks on the smallest boundaries
521 that are suitably aligned for all possible types on the particular
522 architecture YAZ is being built for.
524 --- 2.0.30 2005/01/04
526 Fixed numerious warnings that was issued with newer versions of GCC.
528 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
529 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
532 Make YAZ Generic Frontend Server slightly faster.
534 Enhance (and reduce) logging for Generic Frontend Server.
536 Revert YAZ log system so that it flushes every write operation
537 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
539 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
540 instead of LOG_, due to name clash with syslog(3). LOG_ are still
541 present. New applications should define YAZ_USE_NEW_LOG=1 - this
542 will effectively disable old definitions.
544 --- 2.0.28 2004/11/09
546 Added yaz_log_time_format which specifies log format using
549 Added yaz_log_module_level which returns mask for a module. Value
550 is non-zero mask a if module is enabled; zero if disabled.
552 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
553 in include/yaz/cql.h.
555 Fixed bug #176: Dont throw diagnostics on empty SRU args.
557 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
559 Fixed bug #172: RPM builds does not enable SSL.
561 Doxyfile.in part of dist. Doxyfile generated by configure.
563 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
564 are given and the corresponding component does not exist.
566 Extend CCL documentation in YAZ reference. Describe r=r.
568 --- 2.0.26 2004/10/01
570 Fixed MARC->MARCXML conversion to properly deal with
571 fields, subfields, indicators having non-ASCII characters.
573 Fixed MARC->MARCXML conversion so that ASCII control characters
574 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
577 Added YAZ GFS support for conversion from Z39.50 surrogate
578 diagnostics to SRW surrogate diagnostics.
580 Bug fix: YAZ GFS did not return schema in explainResponse.
582 --- 2.0.25 2004/09/30
584 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
585 now converts recordSchema to elementSetName as well as schema URI.
587 Fixed bug in COMSTACK that prevented HTTP request packages from being
590 --- 2.0.24 2004/09/29
592 Added CCL facility r=r "range" which is similar to r=o "ordered" but
593 does not require white-space before and after the dash in a range, e.g.
594 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
597 Fixed a few AC_TRY_LINK configure tests that did not operate properly
598 due to new GCC removing "redundant" code.
600 Added yaz-client commands scanpos and scanstep that sets preferred
601 position and step-size for scan.
603 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
605 Added CCL utility ccl_qual_buf which parses one or more CCL
606 spec lines in a buffer.
608 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
609 of name and value - ignoring empty lines and comments.
611 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
613 Added odr_get_element_path which returns current element path for an
614 ODR handle. This utility is useful in error handling or user-defined
617 Added ODR_PRINT utility odr_set_stream which is is a more generic
618 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
619 to a write function and pointer to close function. The close function - if
620 non-NULL - will be called during odr_destroy.
622 Fixed bug in CCL parser where truncation char was not removed from
623 right side when truncation=both was in effect.
625 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
628 --- 2.0.23 2004/08/11
630 Fix buffer overrun in CQL parser when dealing with proximity (%).
632 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
633 to UTF-8/UCS conversion is now only based on codetables.xml.
635 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
637 --- 2.0.22 2004/08/06
639 Add support for more "commit changes" in ZOOM (uses Extended Services).
641 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
644 Yet another small fix for configure of SSL.
646 --- 2.0.21 2004/05/14
648 Fix SSL libs for configure when --with-openssl=DIR is given.
650 --- 2.0.20 2004/05/10
652 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
654 SSL comstack now uses yaz.pem certificate file on server side
655 by default. Certificate filename can be configured by calling
656 comstack function cs_set_ssl_certificate_file before cs_bind is used.
658 Fix bug regarding multiple calls to ZOOM_connection_connect.
660 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
662 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
663 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
665 ZOOM now allows inspection of X509 peer certificate for verification.
666 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
668 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
669 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
670 as "modular" but it simplifies things.
672 Added cs_get_peer_certificate to that returns peer X509 PEM.
674 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
675 NULL if SSL is unavailable.
677 Documentation about MARC decoding tools.
679 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
681 --- 2.0.19 2004/03/30
683 Rename CHANGELOG to NEWS to follow GNU style packing.
685 Fix bug with missing initialization of member in init_diagnostics.
686 This bug affects threaded version of GFS server.
688 --- 2.0.18 2004/03/20
690 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
693 Ensure zlib.dll is packed with Windows install.
695 --- 2.0.17 2004/03/17
697 Fix encoding of xsd:string to use text instead of CDATA.
699 Fix endless loop in CQL parser with unbalanced ".
701 Use a more compact way to store MARC-8 conversion tables.
703 --- 2.0.16 2004/03/16 Debian only
705 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
708 Update CQL parser to use new CQL 1.1 modifiers for booleans and
713 --- 2.0.15 2004/03/01
715 Another fix for decoding of XML packed records.
717 --- 2.0.14 2004/02/25
719 Fixes for Chunked encoding. White space not ignored after length spec.
721 Update NS and use default NS for SRW diagnostic elements.
723 --- 2.0.13 2004/02/23
725 Implement ZOOM_resultset_cache_reset which resets record cache.
727 Implement ZOOM_resultset_sort which sorts a result set.
729 Implement chunked HTTP transfer.
731 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
733 --- 2.0.12 2004/02/16
735 Added member 'schema' to bend_explain_rr structure so that backend
736 can specify explain record identifier. Defaults to Zeerex 2.0.
738 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
740 --- 2.0.11 2004/02/16
742 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
745 Added init command for yaz-client which sends "extra" init request.
747 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
748 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
750 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
752 Make ZOOM error code for "invalid query".
754 Fixed compilation for SSL which wasn't properly enabled for all platforms.
756 --- 2.0.10 2004/02/05
758 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
761 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
763 Added option -p <file> to make Generic Frontend Server to write PID file.
765 Added option -D to put Generic Frontend Server in background on its own.
767 Make ZOOM C recognize option "password". If unset, "pass" is used
768 (for backwards compatibility).
770 Fixed a bug in Generic Frontend Server that could make it crash if a
771 client sets characterSetNegotation bit, but didn't pass negotiation stuff
774 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
775 Must be issued before open, in order to be in effect.
777 --- 2.0.9-6 2004/01/12 Debian/Windows
779 Make the SRU server more picky WRT unknown params, etc.
781 Bug fix: ZOOM scan response didn't return displayTerm - when present.
783 New YAZ client command, options, that sets Z39.50 options.
785 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
786 options from a string of tokens (one token for each option bit).
788 Update SRW diagnostic code messages.
790 --- 2.0.9-5 2004/01/07 Debian/Windows
792 Handle user defined stylesheet for SRW/SRU.
794 --- 2.0.9-4 2004/01/06 Debian/Windows
796 Fix bug in decoding of Content-Length.
798 --- 2.0.9-3 2004/01/06 Debian/Windows
800 Fix a bug with decoding of XML packed records.
802 --- 2.0.9-2 2004/01/05 Debian only
804 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
806 Fix bug in SRW/SRU diagnostics decoding.
810 Fixed bug in Generic Frontend Server which could drop records exceeding
811 preferred message size. Reported and fixed by Irina Dijour.
813 Fixed calculation of package size for structured records in Generic
814 Frontend Server. Reported and fixed by Irina Dijour.
816 Fixed namespace for SRW/SRU diagnostics.
818 Fixed SEGV in yaz-client that occured for HTTP connection errors.
822 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
823 this version is incompatible with version 1.0 and older YAZ SRW/SRU
826 CQL changes to reflect recent changes to the specification:
827 * Documentation talks about context sets instead of index sets.
828 * Documentation talks about indexes instead of qualifiers.
829 * The CQL-to-PQF transformer's configuration file now uses
830 "index.set.name = <attributes>" instead of the old form
831 "qualifier.set.name = <attributes>". (Both forms are still
832 understood but the latter is deprecated.)
833 * CQL terms with no explicit index specified are now interpreted as
834 cql.serverChoice instead of srw.serverChoice (which of course
835 behaves exactly the same.)
839 MARC conversion can now generate ISO2709 output in another
840 character set. yaz-marcdump uses this facility if you invoke it
843 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
844 functions from there can be used from C++.
848 Frontend server now transfers memory from decoded packages to stream
851 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
852 references to show up.
854 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
855 the ZOOM Abstract API. The older names for the same options are still
856 also supported for the benefit of old applications.
858 ZOOM-C supports "implementationId" and "implementationVersion" options
859 to go along with "implementationName". These allow the user code to
860 specify identification strings to be sent to servers.
861 Add OID for the new ExtLite attribute set.
863 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
864 as requested/supplid by Ere Maijala <ere@atp.fi>
866 For generic frontend server, reverse the order of
867 "toolkit-supplied / application-supplied" strings sent as implementationId,
868 Name and Version. Also, remove the spaces around the slash. This brings
869 the GFS in line with the behaviour of ZOOM-C on the client side.
871 Add function ZOOM_scanset_display_term.
873 yaz-client shows scan displayTerm if present.
875 Utility yaz-iconv is now installed by default along with the man page
878 Extend configure check for OpenSSL to use pkg-config where available (such
881 Incorporate patch by Morten Bogeskov which allows a Unix file socket
882 server to specify uid/gid/mask for socket using the format
883 unix:[user=uid,][group=gid,][umask=mask,]file=path
884 If file= is omitted the existing format is assumed, e.g.
886 in which case the mask is 0666 (rw for everybody).
888 Major restructure of YAZ source. All source in libyaz is in src directory.
889 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
890 util (utility programs such as ASN.1 compiler, yaz-marcdump).
892 Added man page for utility yaz-marcdump (used to be called marcdump).
893 yaz-marcdump is installed by 'make install'.
895 Fixed a memory leak in Generic Frontend Server that occurred when decoding
896 of incoming package failed.
898 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
900 Change prototype of odr_perror: add const to message string.
902 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
904 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
905 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
906 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
907 DNS lookup. There should not be any compatibility problems with this
908 assuming that blocking=1 or 0 is used.
910 Fix bad reference in UNIX comstack in function cs_addrstr.
912 Fix for compilation on AIX.
914 The generic front-end server (server/seshigh.c) now supports returning
915 Init diagnostics to the client in User-information-field, in
916 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
921 Allow any CQL relation (not just all,any,exact,scr).
923 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
924 that features the same UI.
926 Implemented command update0 in YAZ client which is equivalent to
927 update but uses old of Ext Update ASN.1.
929 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
930 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
931 Previously no OID was used for this info.
933 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
934 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
935 returns 'malformed search term' otherwise.
937 SortResponse member resultCount now set to NULL in sort handler of
940 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
943 Add three new utility functions for translating OIDs between various
944 formats -- symbolic name such as "Usmarc", minus-1-terminated int
945 arrays and dotted strings such as "1.2.840.10003.9.5.1":
946 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
947 char *oid_to_dotstring(const int *oid, char *oidbuf);
948 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
950 Reverted modifications for ES Update definition for z_IU0Update
951 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
952 is back to YAZ 2.0.2.
954 String value attributes for CCL parser.
956 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
957 which their FirstSearch server returns in Init responses, sometimes
958 carrying useful diagnostic information when Init fails. This has the
959 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
960 "z39.50/oclcui.asn", where its definition is somewhat different from
961 what OCLC document on their web-site, as required to interoperate with
964 Support for anonymous authentication in yaz-client. Use the command
967 * Fix the OID of the Index Data-local "admin" Extended Service from
968 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
969 the 1000, which indicates a locally-defined OID, was a mistake.
973 Fix CCL directive @case handling so that it affects string match for
974 both CCL keywords and qualifiers.
976 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
977 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
978 Decoder has been updated with ASN.1 changes as listed in
979 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
980 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
981 z_IUUpdate, remains unchanged.
983 ZOOM_record_get may now return a record in a specific character set.
984 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
985 "from" is the character set of record as returned by target. "to" is
986 the character set to be returned. If omitted, "to" is UTF-8.
988 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
990 New ODR utility, odr_getelement, which returns name of element for
991 which encoding/decoding failed.
993 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
994 in cases where a required element was omitted.
996 Bug fix: some MARC8 sequences were not converted.
998 New ZOOM option "step" which specifies number of records to be
999 retrieved in one chunk. Used in conjunction with "start" and "count".
1001 SRW support for yaz-client. Use scheme http: to use it, e.g.
1004 yaz-client no longer does (un)intelligent character set conversions
1005 by default. Can be enabled with charset and marc_charset commands.
1007 xmalloc trace fix for 64-bit systems such as DEC alpha.
1009 Solaris 2.6 compile fix.
1011 New function, cql_strerror() translates SRW error codes, as returned
1012 by cql_transform_error(), into human-readable English strings. Used
1013 in yaz-client diagnostics when appropriate.
1015 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1016 converts it into a type-1 query which is sent to the server. This
1017 makes CQL available for use with all Z-servers, as opposed to the tiny
1018 minority that can handle CQL queries themselves.
1020 --- 2.0.2 2003/04/28
1022 New Debian package layout similar to the Redhat Package layout.
1024 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1025 and search result respectively.
1027 --- 2.0.1 2003/04/25
1029 Redhat package is now several packages: libyaz (runtime libraries),
1030 libyaz-devel (development and documentation, and yaz (utility programs).
1031 Package spec file by Morten Bøgeskov.
1033 New member 'schema' in struct bend_fetch_rr which the name of requested
1034 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1035 handler MAY set this to reflect the schema of the returned record.
1037 New member 'display_term' in struct scan_entry. GFS now sets member entries
1038 and allocates scan entries to be filled by user scan handler. In previous
1039 version, entries member was allocated by the scan handler. That still works,
1040 but the GFS will ignore member display_term - assuming it was NOT set by
1041 the handler. The fact that the GFS now allocates the entries both allows
1042 for new members and makes a scan handler easier to write.
1044 Fix CQL lex buffer overflow.
1046 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1047 SRU default recordPacking is string.
1049 SRU protocol support for frontend server.
1051 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1053 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1055 Added scan for the ZOOM shell (zoomsh).
1059 * String Identifers for Schemas (Amendment 5).
1060 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1061 Old definition for schema
1062 Odr_oid *schema; /* OPT */
1067 Z_InternationalString *uri;
1068 #define Z_Schema_oid 1
1069 #define Z_Schema_uri 2
1072 * resultCount parameter to Sort Response (Amendment 1).
1073 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1075 Support for SRW 1.0 over HTTP. This is an optional feature and
1076 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1079 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1080 on the same port. SRW SearchRetrieveRequests are mapped
1081 to bend_init,bend_search,bend_fetch,bend_close.
1083 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1085 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1086 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1088 ZOOM connections are SRW based if schem http is used for hostname
1089 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1090 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1092 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1093 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1094 distance=n, order=true/false, relation=le, prox unit=word. If
1095 n is omitted, distance 1 is used.
1097 Fixed problem with C compiler include path in wrong order.
1099 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1100 on Solaris. Patch from Ko van der Sloot.
1102 New MARC decode API. All new functions operate on a yaz_marc_t
1103 handle. The most important new functions are: yaz_marc_create,
1104 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1105 decode and destroy respectively. Decoder can produce formats
1106 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1107 include/yaz/marcdisp.h.
1109 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1110 to UTF-8, UCS-32, wchar_t or Latin-1.
1112 * Prototypes for yaz_iconv_-functions moved to separate header
1113 include/yaz/yaz-iconv.h.
1115 Make a few private functions 'static' in unix.c. This prevents
1116 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1118 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1119 are set when Init Response is received.
1121 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1122 but returns diagnostic set as well.
1124 New function yaz_strerror which is a portable wrapper for
1125 strerror/strerror_r/GetLastMessage.
1127 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1128 is returned for MARC. If type is "oai", then OAI MARC is returned.
1130 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1133 --- 1.9.2 2002/11/26
1135 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1137 Fix bad race conditions on SIGTERM and terminate gracefully in
1140 Move retrieval (data1) module to Zebra since nobody seems to be
1143 Add GRS-1 render for ZOOM using same format as yaz-client.
1145 --- 1.9.1 2002/10/05
1147 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1149 Fix broken ESpec handling in data1 module.
1151 SGML reader parses comments and makes them part of the data1 tree.
1153 Added several type casts so that YAZ compiles as C++ code.
1155 ZOOM didn't handle PDU encoding failures properly.
1157 Added more Bib-1 diagnostics (approved extensions).
1159 GNU configure: better check for iconv.
1161 More portable use of accept, getpeername. Check for socklen_t. Use
1162 int/size_t if socklen_t is not defined.
1166 PQF parser rejects bad queries - including those with extra
1167 characters in them. PQF parser used to silently ignore that.
1168 Cleaner API for PQF added, which allows you to get detailed
1169 error information for bad queries (see yaz/pquery.h).
1171 Fixed bug in ZOOM_record_get for type "database".
1173 Implemented mini iconv library supporting conversions between
1174 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1176 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1178 --- 1.8.9 2002/08/20
1180 Fixed ZOOM C record cache so that preferredRecordSyntax and
1181 elementSetName is used to check for already fetched records.
1183 --- 1.8.8 2002/08/02
1185 Added three members in bend_initrequest structure to facilitate
1186 character set negotiation.
1188 Fixed a bug in frontend server that could cause indefinite
1189 loops under rare conditions.
1191 Revised character set utilities (charneg.h) so that encoding
1192 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1194 For PQF, directive @term <type> sets term type for Scan/Search.
1195 Here <type> is general, string, numeric, null. The term type
1196 is inherited - just like @attr.
1198 New call odr_set_charset that sets character set conversion for
1199 international-strings on a ODR stream. Prototype is:
1200 int odr_set_charset(ODR o, const char *to, const char *from);
1201 The InternationalString is still represented as C string in YAZ
1202 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1203 won't). On the protocol level, you can use any encoding.
1205 Support for UNIX sockets in ZOOM.
1207 Solaris recv sometimes returns errno == ENOENT. It is treated as
1208 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1210 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1211 both client and server. Code by Morten Bøgeskov.
1213 --- 1.8.7 2002/05/22
1215 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1216 that they can be used directly from Visual Basic. You must recompile
1217 your windows APP if you're using ZOOM.
1219 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1220 Commands "lang" and "charset" sets language and character set respectively.
1221 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1222 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1224 Attributes from multiple CCL fields may be OR'ed rather than merged
1225 using directive "@field or". Fields are still merged by default -
1226 equivalent to "@field merge".
1228 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1231 Fixed bug in zget for parameter ExtendedServicesResponse.
1235 --- 1.8.6 2002/03/25
1237 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1239 Client displays USR.1:SearchResult-1 (hits per term).
1241 Additional Search Info for search in Generic Frontend Server.
1243 Fixed CCL parsing of "field=s".
1245 WIN32 installer - using the excellent NSIS software from nullsoft.
1247 Fixed CCL parsing of "field = - <number>".
1249 Added function yaz_marc_decode that decodes MARC for line mode
1250 display or XML (similar to that used by JZKit).
1252 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1253 Z39.50. But ISO/ILL was, however.
1255 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1256 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1261 --- 1.8.5 2002/02/03
1263 New YAZ client features: Command completion and new commands:
1264 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1265 Code provided by Jacob Poulsen.
1267 New call oid_trav, that visits all registered OIDs via callback.
1269 Function ZOOM_record_get now returns const char pointer rather than
1270 void pointer. It saves a lot of type casts.
1272 For YAZ client, command "auth" now allows you to set authentication
1273 in IdPass style. It is enabled when three tokens are given - order
1274 is user, group and password.
1276 Fix memory leaks in MARC record handling for ZOOM.
1278 New option for YAZ client, -k <kilobytes> that sets
1279 maximum record size. Similar to -k option for generic frontend
1280 server and yaz-ztest.
1282 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1284 Prefix query parser reports "fail" when bad attribute set is given.
1286 Fix in MARC decoder. Proximity logging. Fix for attribute set
1287 in scan handler for server. Patches by Shigeru Ishida.
1289 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1292 Configure option --with-openssl=<dir> now works when a directory is
1293 specified. Patch provided by Morten Bøgeskov.
1295 New option for YAZ client, -u <auth>, that sets authentication.
1297 ZOOM fix: error information was sometimes "missing", since error
1298 was cleared/reset too when it shouldn't.
1300 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1302 --- 1.8.4 2002/01/04
1304 Scan for ZOOM API. New object ZOOM_scanset. New functions
1305 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1306 ZOOM_scanset_destroy.
1308 New ZOOM function, ZOOM_connection_last_event, that returns type
1309 of last event (such as "receive data", "send data", "apdu received",
1312 New ZOOM option, schema, that specifies schema for retrieval.
1314 New CCL feature. Qualifiers can be aliases for one or more
1315 other qualifiers (if more than one is given, OR is used).
1317 ZOOM uses named result sets if target supports it.
1319 Two new YAZ client commands: . (dot, which sources a script of YAZ
1320 client commands), and ! (to execute shell command.). Implemented
1323 Working on Debian packages.
1325 --- 1.8.3 2001/11/19
1327 YAZ client enables named result sets only if target supports it.
1329 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1331 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1332 with key="host" to get same result.
1334 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1335 Function Z3950_resultset_record(s) returns references to records
1336 "owned" by resultset. To become owner use Z3950_record_clone.
1338 Function z_ext_record handles Extended Services. Thanks to
1341 --- 1.8.2 2001/11/12
1343 CCL Parser fix: ignore token comma when dealing with and-lists.
1345 Documentation updates for COMSTACK.
1347 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1348 Changed prototype Z3950_records. For some functions, int parameters
1349 were changed to size_t.
1351 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1354 New MARC decode/display function, marc_display_exl, which properly rejects
1355 non-ISO2709 records. YAZ client uses it.
1357 --- 1.8.1 2001/10/29
1359 Fix bug: local attribute set wasn't set correctly in PQF strings.
1363 * Old Z39.50 codecs no longer supported.
1365 Added ZOOM C binding. See http://zoom.z3950.org/
1367 Renamed states for COMSTACKs to avoid confusion with events.
1369 Implemented cs_look and proper cs_rcvconnect.
1371 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1373 Configure detects POSIX threads on OpenBSD.
1375 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1376 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1378 When error is returned from present handler, non-surrogate diagnostic
1379 is returned in present response (and fetch handler is no longer called).
1381 * Minor adjustments to pquery parser (PQF). Token characters may be
1382 escaped by using backslash (C-style).
1384 PQF parser allows string attribute values to be specified. For @attr,
1385 non-numeric characters after the equal-sign are treated as strings
1386 (e.g. @attr 9=title).
1388 CCL trunction character may be defined (@truncation in file)
1390 * function zget_ExtendedServicesRequest sets waitAction to
1391 waitIfPossible (was wait).
1393 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1396 CCL operator names may be set in field definition files (CCL_bibset).
1397 See ccl/bib1 for an example.
1399 Fixes in ASN.1 compiler for C++ compatibility.
1401 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1402 and "op_or" to avoid conflict with C++.
1404 Fixed problem with GNU readline detection on Redhat 7.0.
1406 Added step-size for Scan backend handler.
1408 Fixed bug that made the frontend server crash when no attribute
1409 set was specified for scan.
1411 Front-end server automatically switches to original working directory
1412 when installed as an NT service. Previously -w had to be specified to
1415 Added extended attributes for retrieval module (data1), so that data1
1416 records carry d1_readXML/SGML attributes. d1_read also supports
1417 null-data rules ( <tag/>)
1419 On UNIX when POSIX threads are available, a separate library libyazthread
1420 is created. Programmers should link with that library and the yaz library
1421 when using threads. The reason for the split was that some applications
1422 on Linux, such as Apache, doesn't work well when using shared objects that
1425 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1426 (or any frontend server) in SSL mode by specifying ssl: followed by
1427 address. Only tested on UNIX.
1429 Added feature for CCL module. Virtual structure s=al or s=ol generates
1430 and-list and or-list respectively instead of phrase search.
1434 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1435 log_mask_str. This was done to avoid name conflicts with other libraries
1436 (such as other PHP extensions).
1438 Added raw OID member for preferred record syntax (request_format_raw)
1439 and returned record syntax (output_format_raw) for backend fetch method.
1441 Config file yaz-config now accepts options so that it returns specific
1442 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1444 Shared library support for UNIX using GNU libtool.
1446 * Modified backend interface. Request/Response struct's replaced by
1447 one read/write C struct. For example bend_fetchrequest and
1448 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1449 Every handler - even search has to be registered in bend_init
1450 handler. This means that the YAZ library no longer refers to
1451 external functions and it makes it possible to make the whole
1452 thing a single DLL/SO.
1454 Added Segment handler for backend server.
1456 Added Zmbol/Zebra administrative functions to YAZ client.
1458 Threaded frontend server on UNIX (when POSIX Threads are available).
1459 Starting the server with option -T enables multi-threading.
1463 Added configure option --enable-comp/disable-comp to control use
1464 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1465 located in sub directory asn.
1467 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1468 in ${exec_prefix}/bin along with the other programs yaz-client and
1471 GNU automake used to maintain makefiles.
1473 Added several OID's.
1475 Changed retrieval module so that we can load records with no abstract
1476 syntax defined. Tagpaths in these records are fully composed of string
1479 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1483 On UNIX, the generated makefile now supports a proper 'make install'.
1484 The prefix can be set via GNU configure to set the install location
1485 (default is /usr/local).
1487 * YAZ programs client and ztest were renamed to yaz-client and
1488 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1489 locations, such as /usr/bin,/usr/local/bin,etc.
1491 * YAZ Header files were moved from include to include/yaz. YAZ Header
1492 files are referred to as include <yaz/log.h> rather than <log.h>.
1493 The YAZ include path (-I ..) is therefore the same as before. Programmers
1494 should update their #include statements or use -Ipath/include/yaz
1495 instead. The main motivation for doing this change is that YAZ header files
1496 can be installed in "standard" locations /usr/include,/usr/local/include
1497 without introducing conflicts, since ALL YAZ header files are stored
1498 in subdirectory yaz (under /usr/include for example).
1500 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1501 rather than project/workspace files. We switched because project files
1502 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1505 Changed name of logging function, logf, to yaz_log, to prevent name
1506 clash with some math-log functions. The YAZ header log.h defines logf
1507 to yaz_log (#define) so there should be no incompatibilities by this
1510 Added bend_start/bend_stop handlers for server. These handler are
1511 called on start/stop of server. For windows they are called whenever
1512 a service is started/stopped.
1514 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1515 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1516 in util/yc.tcl. The auto-generated C code structures are, in a few
1517 cases, incompatible with the old decoders. There are differences in the
1518 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1519 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1520 The preprocessor variable ASN_COMPILED is defined when the compiled
1521 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1522 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1523 wish to use the old encoders/decoders you can specify --disable-yc
1526 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1527 version so that it supports both new - and old version of DB Update
1529 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1530 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1531 change. The name parameter can be set to 0 in which no name is specified
1532 for the construction. The macros odr_implicit and odr_explicit sets name
1533 parameter to zero for the construction involved. New macros
1534 odr_implicit_tag and odr_explicit_tag are similar to the others,
1535 except that a name parameter is added. For programmers' that don't use
1536 ODR they probably only need to change the call to z_APDU and z_External.
1538 Added access control facility by interfacing the TCP wrapper library.
1539 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1540 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1541 name of the daemon and enables the access control as specified in
1542 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1544 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1545 den Dool <H.M.vdnDool@kub.nl>.
1547 Added reference ID parameter to most functions in server API - refer
1548 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1550 Changed name of ccl library to libccl.a (was ccl.a).
1552 Fixed bug in decoder for Explain (Category TargetInfo).
1554 Added support for GNU readline in client. Thanks to Jacob Poulsen
1555 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1557 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1558 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1559 IMPLEMENTATION! This change was made to the development version before
1560 the ZIG decided to retract the amendment. If any users MUST be
1561 compatible with the original Update definition, PLEASE CONTACT US, and
1562 we will include a separate definition corresponding to the old Update
1563 ES. Note that because of the change to the ASN.1 of the
1564 TaskPackageRecordStructure we cannot define a single structure that
1565 will support both versions.
1567 * Added const modifier to buffer parameter for some ODR/BER encoding
1568 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1569 completeWAIS, odr_dumpBER.
1571 Fixed bug in client.c which caused a crash when a scanResponse didn't
1572 contain positionOfTerm.
1574 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1575 * will cause an error in a client if a non-YAZ target sends both a
1576 * list of Scan entries and non-surrogate diagnostics.
1578 Retrieval module enhancements. Tag sets may be typed in the reference
1579 to it. From the .abs-file the "tagset" directive takes a third optional
1580 integer type for the tag set referenced. From a .tag-file the "include"
1581 directive takes a third optional type as well. The old "type" directive
1582 in the tag set itself is still recognized but acts as the default type
1585 Backend interface change. Individual Scan terms returned from bend_scan
1586 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1587 in include/backend.h.
1589 Retrieval module enhancements. Multiple tag sets and attribute sets may
1590 be specified in abstract syntax specs. Revised the error/warning for
1591 logging messages reported by the retrieval module when reading the
1594 Object Identifier system (oid_..) changed. The API is backwards
1595 compatible but the oid-routines now allocates new OID's when needed.
1596 Raw OID's may be specified in oid_getvalbyname.
1598 YAZ now uses GNU configure to generate Makefile(s).
1600 * Minor changes in some of the member names of DeleteResultSetRequest and
1601 DeleteResultSetResponse. See include/proto.h.
1603 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1604 and added member 'languages' in TargetInfo (which was missing).
1606 Changed the way attribute sets are handled in the retrieval
1607 module. These are now cached, just like the abstract syntaxes
1610 Changed YAZ so that it links with compiled ASN.1.
1612 Added Explain-schema definitions and mapping routines. The following
1613 Explain categories have been implemented: AttributeDetails,
1614 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1616 Fixed minor bug in Windows version of Server Library.
1618 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1620 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1622 Added EXTERNAL: UNIverse Resource Report (non-standard).
1624 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1625 ENUMERATED and SET OF.
1627 * Added 'const' to some of the char pointer arguments for the
1628 functions, data1_read_node, data1_getelementbytagname,
1629 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1632 Fixed bug in data1_insert_taggeddata - the last_child member of
1633 parent wasn't initialised.
1635 * Changed data1_read_record and data1_read_node so that the supplied
1636 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1637 doesn't refer to any parts of the "SGML"-buffer.
1639 Fixed bug in server library (Windows version of statserv_remove).
1641 * Changed code so that it compiles as C++. The type definition
1642 of Odr_fun which is a member of Odr_arm was changed. The result is,
1643 that an explicit typecast is needed for the fun pointer when
1644 using Odr_arm - as in:
1645 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1647 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1649 Implemented the new structured date and time definition as approved
1650 by the ZIG. Added schemaId element to the specificTag in Espec-1
1651 (also approved at the last ZIG). Thanks to RVDM.
1653 Added some Object identifiers (RVDM).
1655 Changed the Update Extended Service (RVDM).
1657 Added command "refid" to client which specifies referenceId for
1658 the following requests.
1660 Implemented extended service handling for server. See ztest.c
1661 for an example as well as backend.h. New handlers are registerd
1662 in the Init handler.
1664 * Changed interface for sort in server.
1666 Added new members to statserv_options_block. It allows a server
1667 to read options from another source than just the command line. Thanks
1668 to Charles Woodfield.
1670 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1671 renamed to zboolean. Some C++ compilers complained about the name.
1673 Minor changes to gils.abs. Added index 's' (sort) on title
1674 and date/time-last-modified.
1676 --- 1.4pl2 1998/1/30
1678 Fixed bug in server library regarding inetd mode (-i). This bug
1679 was introduced by release 1.4.
1681 --- 1.4pl1 1998/1/29
1683 Added sort facility in client and backend server interface.
1685 Fixed problem with dependencies in Makefile(s).
1687 Fixed bugs for encoders/decoders of extended services and
1690 Implemented sub-tree feature for schemas. Sub-trees are
1691 referenced in *.abs-files. See explain.abs for an example
1692 of the use of this feature.
1694 Modified bib1.att; local attributes for ANY didn't include
1695 ANY itself (only affects use of the retrieval module).
1697 Fixed bug in plain SGML reader in function data1_read_node:
1698 tags with prefix "var" was incorrectly interpreted as variants.
1700 Added feature "sub-schemas" to enable references to - and definitions
1701 of - group of elements.
1703 * Removed member parent from type data1_element (in data1.h).
1705 Implemented function odr_nullval() that returns the value of
1708 * Removed member num_children from data1_node (in data1.h).
1710 Made NT service interface part of the server library. The
1711 function statserv_main uses the NT service when required and
1712 calls the statserv_start / statserv_close routines.
1714 Routine zget_SearchRequest and zget_PresentRequest fills
1715 resultSetName/Id member with "default" instead of "Default".
1717 Fixed memory leak in server. Request queue member wasn't freed.
1719 Fixed nmem_exit so that memory is freed.
1723 Revised the CCL parser utility to be thread safe.
1725 Added function, oid_ent_to_oid, to replace the function
1726 oid_getoidbyent, which is not thread safe.
1728 * Added nmem_init and nmem_exit to initialize and release
1729 NMEM resources. Function nmem_init should be called once in the
1730 initial thread before NMEM/ODR is used. statserv.c and client.c
1731 have been changed accordingly. The change was necessary to make
1732 NMEM thread safe. The NMEM memory pool is shared amongst threads
1733 in a process. Unix-based applications will still work fine without
1736 Added NT Services interface for the the Z39.50 (statserv) Server.
1737 Refer to the ztest.c source on the usage.
1739 Windows 95/NT port using MSVC5.0. Project files are included in the
1742 * Defined new 'global' handle for the retrieval (data1) system. The
1743 new handled, data1_handle, describes the state of the data1 system.
1744 This handle is passed as first argument to virtually all
1745 data1 related routines. The functions data1_create and data1_destroy
1746 creates and destroys a data1 handle respectively.
1748 Added ODR encode stream member to all backend request structures
1749 init, search, scan etc. This stream should be used to allocate all
1750 memory used for the response when thread safe operation is needed.
1752 Changed the comstack utility, cs_addstr, to be thread safe. The
1753 returned hostname string returned by the function is now part the
1756 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1757 function. The cs_straddr takes a COMSTACK handle as argument, so this
1758 function must be used after cs_create and before bind/connect.
1759 This function is thread safe.
1761 Moved test server to 'ztest' directory - generic server code still
1762 in 'server' directory.
1764 Made prefix query (pquery.c) utility thread safe.
1766 Added new function modifier YAZ_EXPORT to 'export' public DLL
1767 functions when using windows (see include/yconfig.h).
1769 Added definitions to the OID database (util/oid.c) (RVDM).
1771 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1773 Added call to ccl_rpn_delete in client program.
1775 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1776 release of RPN structure.
1778 Added support for C++, headers uses extern "C" for public definitions.
1779 With input from RVDM.
1781 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1782 Thanks to Ronald van der Meer (RVDM).
1784 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1786 Added support for private extensions to the OID database
1787 (oid_setprivateoids()). Thanks to RVDM.
1789 Added optional, physical ANY (key replication)
1791 Fixed null-reference problem in GRS-1 output filter.
1793 Proximity operator added to Prefix Query Format (PQF).
1795 In test client command "base" accepts multiple databases.
1797 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1801 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1803 Smallish bug-fixes in the new encoders/decoders (explain).
1805 Bug fixed in DeleteRequest.
1807 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1809 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1811 Added SOIF syntax (using private OID for now) to retrieval module and client.
1813 Added Update extended service.
1815 Added SearchResult-1 additional info structure.
1817 Added optional CCL (ISO8777) interpreter as separate module. Available
1820 --- 1.2 1996/6/10 (1st anniversary release)
1822 Added Summary record syntax. Lightly tested.
1824 Added OPAC record syntax. Untested.
1826 Added ResourceReport service encoders/decoders. Untested.
1828 Fixed bug in z_Unit - wrong tagging on unitSystem.
1830 Fixed bug in the DiagRecs decoder.
1832 Added options for max PDU size and session timeout to frontend-server.
1834 Added documentation of query-language parsers and other supporting utilities.
1836 [frontend-server] Added Attribute set to the bend_scanrequest API.
1838 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1839 surrogate diagnostics were generated.
1841 [retrieval] Allow multiple local values for attribute.
1843 [retrieval] Allow multiple attributes per element in .abs files. index type.
1845 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1847 --- 1.1pl2 1996/4/10
1849 Minor changes, mostly specific to Zebra's requirements (retrieval)
1853 Repaired bug in frontend server when running multiple listening
1854 endpoints in dynamic mode.
1856 z_External() now won't break if a known, ASN.1 value comes encapsulated
1857 in an octet-string. The value will pass through unmodified in an Odr_oct.
1859 Added a bit of code to the demo client to decode & display
1860 ASN.1-structured records represented in the octet-aligned branch of
1861 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1863 Added z_ext_getentbyref() to the ASN module. Doc updated.
1865 * Completed the SCAN definition in the ASN module. This may break SCAN
1866 code based on older YAZ-versions at compile-time. The fix is easy -
1869 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1870 under the SCAN definition. Remember to initialize this, server-people.
1872 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1873 that this does not extend to ODR and ASN.
1875 Comstack allows insertion of established socket (primarily for
1876 inetd-operation of servers). Doc updated.
1878 Front-end server can now start from the inetd in TCP mode. Doc
1881 --- 1.0pl4 1996/1/24
1885 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1886 the rank and record number.
1888 Adjustments to the frontend server.
1890 Fixed diagnostic BER dumper. It ignored the file argument.
1894 Various changes to retrieval module.
1896 Changed the union discriminators of the protocol files from enums to
1897 ints paired with #defines.
1899 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1902 *Changed operator in the RPN structure to 'roperator', again to avoid a
1905 Fixed problems in Explain decoders/encoders.
1907 --- 1.0pl2 1995/12/6
1909 Memory bug in log module fixed.
1911 --- 1.0pl1 1995/12/5
1913 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1915 Bug in Explain DatabaseInfo module fixed.
1917 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1921 The shift to v1.0 signals that we now consider the *core* functionality
1922 of YAZ reasonably stable (the core being more or less equivalent to
1923 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1924 tested (Explain not at all - though that will happen soonish).
1926 Minor changes to code to support Windows port.
1928 Various minor changes after we're getting to use GRS-1 & co. more.
1930 Added Espec-1 format.
1932 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1933 of the protocol and it cannot be selected when encoding (maps into 'string'
1934 when decoding). Needed to talk to some servers.
1936 Demo client can request simple element set names.
1938 Added Diagnostic Format encoders/decoders.
1940 Added simple Close handling to frontend server (no hooks for resource
1941 reporting yet), and demonstration client.
1943 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1945 --- 1.0b3 1995/08/24
1947 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1948 handled incorrectly when records were requested in the searchResponse. This
1949 will only affect you if you use the frontend-server.
1951 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1952 Test-client will ask for and print GRS1. Ztest will return dummy records
1955 Added Explain encoders/decoders to the service-level API. Untested.
1957 Added Extended Services: Item Order encoders and decoders to the Service-
1958 level API. Untested. We could use a recent copy of the pertinent bits
1959 of the ILL protocol to add those bits.
1961 Added diagnostic format 1 encoders/decoders to the service-level API.
1964 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1965 odr_cons.c, which causes a more correct output.
1967 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1968 was always set to 0 when no records were requested in the searchRequest.
1970 * Added better external-handling. This shouldn't harm old code that
1971 *encodes* externals. It can break code that looks for a
1972 'single-ASN1-type' representation, since those types that are known
1973 are now decoded immediately. Look at the SUTRS sample code in
1974 seshigh.c and client.c. Documentation updated.
1976 Handling of structured records in bend_fetchresponse. Length -1 marks
1977 structured record, type is deduced from format field.
1979 --- 1.0b2 1995/06/27
1980 Fairly quick maintenance release to add SUTRS support.
1982 Fixed handling of SUTRS records in the demonstration client.
1984 * Added format field to the bend_fetchrequest and bend_fetchresponce
1985 structures of the backend API (frontend server). When the record is
1986 returned, the value of the format field is mapped to an OID. The
1987 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1988 of the record. The special value VAL_NONE in the bend_request means
1989 that no specific format was requested by the client. Documentation
1990 updated accordingly. Test server (ztest) will return a fixed dummy
1991 SUTRS record if your client requests SUTRS.
1993 Documentation updated accordingly.
1995 You can now set external libraries and RANLIB support in the top-level
1999 First public release.
