3 yaz-client: don't display bogus records from SRU servers. Some SRU servers
4 return more records than given by *maximumRecords*. Skipping those in
7 record_render: simplify buffer return handling and fix at least one bad
8 memory reference, that broke the test_embed_record sometimes.
10 Allow http://user:pass@host notation for yaz_url_exec.
12 zoomsh: allow shell command to be executed. Via the system(3) call.
14 yaz_poll: Allow num_fds == 0
16 yaz-client: fix bad encoding of "itemorder item". The itemorder
17 item <no> - command forgot to use length of encoded Item Request
18 package. Error present since YAZ 3.
20 yaz-ztest: fix bad usage of session handle. Bug was introduced when
21 result sets were saved (271a9c83).
23 SRU recordPacking: guess record packing in response rather than looking
24 at the recordPacking element which, OF COURSE, changed semantics in SRU
27 Decode SRU 2.0 responses. The official namespace for responses, according
28 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
29 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
30 nature.com's server, however, usee namespace
31 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
32 we are now using a glob-expr to match up the namespace. ZOOM C and
33 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
34 I can not find a single real example showing the "real" namespace in
35 the documentation from OASIS. The namespace for requests is different
36 from responses, but this is not added to YAZ yet, when we don't encode
41 zoom/record_render: add support for Base64 decoding fo MARC records
42 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
43 which will decode base64 + ISO2709 marc-8 encoded material from text node
48 Add missing definitions ZOOM_resultset_get_facet_field_by_index
49 and ZOOM_resultset_facets_names.
51 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
54 Change APDU dump printing to avoid long leading blanks. For levels 16
55 or larger the level is shown and the indentation is truncated but
56 recursed with modula 8. This makes it still reasonable easy to read
57 - even for nested BER dumps.
59 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
60 return 0 (incomplete package) in case where the BER package was
61 considered too nested (return value of -2).
63 dumpber: lines of level 15 are not indented further. Two spaces per
64 indentation; indentation 15 or more is indented to a fixed indentation
65 and augmented with a level=<no> indication.
67 zoomsh: increase max size of command+args
69 GFS: No limit in RPN buf size in CQL to RPN conversion.
73 New function for daemon utility, yaz_daemon_stop .
75 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
79 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
80 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
84 YAZ daemon utility relays SIGUSR1 to child process.
86 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
87 would result in en empty database list - which in turn would result in
88 encoding failure for search.
90 Fix reading beyond string in yaz_sort_spec.
94 Add two new SRU diagnostics:
95 236: Access to specified database denied
96 1015: Init/AC: Maximum number of simultaneous sessions for Userid
98 Document the very useful ZOOM-C option "apdulog".
100 CQL to RPN: term may be passed through verbatim. This is enabled with
101 truncation.cql . The assumption being that the term is already CQL.
103 --- 4.2.29 2012/03/20
105 record_conv: leader spec may be given for marc element.
106 The leader spec is given as attribute leaderspec for element marc.
107 For example to convert a MARC21 record from MARC-8 to UTF-8:
108 <marc inputformat="marc" outputformat="marc"
109 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
111 record_conv: allow user-XSLT params. For example:
112 <xslt stylesheet="MARC21slim2DC.xsl">
113 <param name="myparameter" value="myvalue"/>
114 <param name="otherparameter" value="othervalue"/>
117 record_conv: fix error handling for missing marc charsets.
119 CQL: fix extra terms in wrong order.
121 --- 4.2.28 2012/03/06
123 record_conv: modify new API for conversion types. The conversion types
124 may be passed in new functions yaz_record_conv_configure_t and
125 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
127 Avoid mixed statement/variable declare; fixes compilation with Visual
130 --- 4.2.27 2012/02/28
132 Add non-standard SRU diagnostic: 235: "Database does not exist".
133 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
134 Update SRU to Bib-1 diagnostic maps accordingly.
136 CCL: add two new diagnostics for unsupported masking. The new
137 diagnostics are: "Embedded truncation not supported" and
138 "Single charcacter mask not supported".
140 --- 4.2.26 2012/02/23
142 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
144 --- 4.2.25 2012/01/11
146 Build YAZ for Ubuntu Oneiric.
148 CCL: allow parantheses for proximity operands. For example CCL query
149 (a) % (b) is now allowed.
151 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
152 marked dead, rather then being destroyed. If not, the session memory is
153 being free'd before the search/scan handler is finished. Also destroy
154 'request' memory in request_release rather than in various places,
155 which resulted in leaks from time to time.
157 --- 4.2.24 2011/12/21
159 cql_sortby_to_sortkeys: honor sort prefix.
161 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
162 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
163 The rpn2cql family of functions now always returns quoted CQL terms.
165 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
167 --- 4.2.23 2011/12/15
169 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
170 sequence is treated as one. For example, &&a=b&&&c& is identical to
173 --- 4.2.22 2011/12/05
175 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
176 APDUs for a connection to a WRBUF.
178 --- 4.2.21 2011/11/23
180 Fix cql_sortby_to_sortkeys. Completely broken before.
182 Make CCL's @truncation work again.
184 --- 4.2.20 2011/11/09
186 New ZOOM connection setting: tproxy. It's like proxy, but does not
187 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
188 to set resolved address + port for a connection outside ZOOM itself.
190 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
192 --- 4.2.19 2011/11/07
194 Fix uninitialized variable in Solr spell support (could cause SEGV
195 for SRU response decoding).
197 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
198 back-end's addinfo through into the ZOOM response addinfo.
200 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
201 they are separated by a colon and a space rather than simply
204 --- 4.2.18 2011/10/28
206 Add support for Solr spell-checking/suggestions through ZOOM.
207 If a Solr target has been configured correctly for spelling-checking
208 and suggestions, these will now be returned on the ResultSet option
209 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
211 --- 4.2.17 2011/09/28
213 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
214 with a flag whether to substitute escape sequences or not.
216 --- 4.2.16 2011/09/22
218 Fix nmem_strsplit_escape to substitute escape char properly.
220 New option for zoomsh -e , which makes it abort on first error and
221 return process exit code to indicate success/failure.
223 YAZ options utility supports special option -- which makes all it treat
224 all following arguments as non-options.
226 --- 4.2.15 2011/09/16
228 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
229 searched if absolute filename is given.
231 Fix conv_xslt() error-reporting when stylesheet is not found.
232 (The value of fullpath is meaningless in this situation.)
234 --- 4.2.14 2011/09/07
236 Fix problem in CQL sort node creation: un-initialized memory.
238 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
239 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
240 CQL sortby depending on whether Type-1 or CQL is actually sent to the
243 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
244 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
246 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
247 will make it possible to use both single-character mask (#) and wildcard (?)
248 in CCL . Throw diagnostic for left truncation because that is not supported
251 --- 4.2.13 2011/09/01
253 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
254 cases using escapes (\-sequences) and masking.
256 PQF parse fix: A trailing backslash followed by end-of-string (\0)
257 would result in a read one byte beyond string.
259 rpn2ccl may use Z39.50 masking for terms (t=z).
261 ICU check fix. Don't include library -lCrun on Solaris, unless present.
263 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
264 not --cppflags (which seeems like an error in icu-config).
266 --- 4.2.12 2011/08/27 RPM package only
268 cql2ccl: fix conversion of terms: operator characters were not
271 --- 4.2.11 2011/08/25 RPM package only
273 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
274 CCL parser will map both # and ? to their regular expression
275 quivalents (. and .*).
277 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
278 of reserved CQL characters.
280 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
281 is, so that they are passed through.
283 --- 4.2.10 2011/08/24
285 ZOOM SRU mode: more aggressive re-connect.
287 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
288 made available as a utility function, declared in <yaz/logrpn.h>
290 rpn2cql_structure() supports proximity nodes (except that the Type-1
291 proximity node's "exclusion" binary is ignored, as there is no way to
292 express that in CQL). Fixes bug #4564.
296 Fix SEGV that could occur if set command of zoomsh was given without
297 value (2nd argument).
299 Fix SEGV that could occur if unsupported transport was given for
300 COMSTACK - say https (when SSL was unavailable).
302 Build yaz-url on Windows too.
306 New utility to get web content. Header is url.h. A command line tool
307 yaz-url is part of the distribution and packages.
309 Fixes for SSL COMSTACK (when gnutls is in use).
311 New functions yaz_base64{encode,decode}. Header is base64.h.
315 ZOOM C includes HTTP response buffer as additional info if it fails
316 to decode the SRU response.
318 Make wrbuf_json_puts available.
322 zoom: throw diagnostic for invalid value for option "sru". Before a
323 bad SRU request was sent.
325 Adding new utility wrbuf_vp_puts.
327 Add cclxmlconfig.obj to win/makefile. It was missing completely.
331 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
332 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
333 redirect was used at the same time.
335 MARC line mode decoding: be less picky about length given - first
336 5 digits of header that is.
338 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
340 Changes to decoding of SRU records: a record with recordPacking=xml is
341 modified with a new root element <yaz_record> if the recordData contains
342 multiple children elements. This is to make the record XML parseable
345 RPN to SOLR conversion: encode special characters.
347 Generic Frontend Server: fix uinitialized member, stepSize.
351 Fix a bug in SRU decoding of records.. The database records stored
352 had un-initialized memory, but it would only be seen with yaz_record_render
353 and type_spec="ext" .
355 Fix a bug in ccl_qual_dup introduced in 4.2.3.
359 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
363 Add new utilities to convert from CQL to CCL . These utilities have
364 prefix cql_to_ccl defined in cql.h.
366 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
367 lead to memory heap corruptions when ICU utilities were in use.
371 Make compilation work without Libxml2.
373 yaz-client: remove redundant blanks in display of searchResult-1 term
378 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
379 resulting CQL node (tree) in a new node CQL_NODE_SORT.
381 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
382 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
383 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
384 Note that the CQL sortby spec is only converted when the GFS is already
385 converting from CQL to RPN (cql2rpn element).
387 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
388 specify whether to collapse delimitors or not. The existing nmem_strsplit
389 do collapse (collapse parameter = 1).
391 Windows installer: For NSIS, set InstallDir depending on x86/x64.
393 Rename internal func yaz_use_attribute_create. While non-static, this
394 function is not declared in a public header.
398 Add -lCrun when linking with ICU on Solaris.
400 More quicks character set conversions for OPAC records.
404 fix problem with record_render: records were converted (character set
405 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
409 SRU: add methods for handling DADS SRU-proxy facets.
411 Separate OPAC record character set for ZOOM_record. yaz_record_render
412 allows a character set given as charset=from/opacfrom,to where 'from' is
413 the character set of a bibliographic record, 'opacfrom' is character set
414 of OPAC record and 'to' is the target character set.
418 yaz-client: show may XML format records. Command show followed by 'format'
419 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
422 src/stemmer.c: Avoid using unnamed union. It is not supported by some
425 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
428 Update yaz.spec to operate on both SLES11 / Centos 5.5.
430 RPM: Release includes 'indexdata' name. Use indexdata in release name so
431 this package can be distinguished from other vendors.
433 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
434 as determined by configure
436 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
438 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
439 returns no error and no record, the present request is considered
440 partial (only a subset of the records could be returned by backend), and
441 so it is appropriate to set Present Status to partial-4.
445 Move yaz-config man pages to section 1.
447 More documentation about SOLR.
449 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
450 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
451 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
452 peers on some Linux systems. However, in general that does not work
453 so YAZ can not rely on that to work. Debian changed behavior in this
454 respect from Debian lenny to Debian squeeze (still testing as of Oct
456 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
458 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
462 Fix yaz-config output: echo_source not set correctly by configure.
466 SOLR WebService support for yaz-client and ZOOM.
468 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
470 --- 4.0.12 2010/08/17
472 Z39.50 facet support. Facet specifications are passed for search in
473 other-information with ASN.1 as defined in facet.asn and OID
474 .10.1000.81.5 . Facets are expressed as an Attribute list as known
475 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
476 3 is limit (number of entries to get in response). yaz-ztest returns
477 dummy facets if a client asks for them.
479 --- 4.0.11 2010/07/09
481 CCL fixes: bug 2895 and bug 3539.
483 GR1-display: add comma in display - was removed by mistake in
486 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
488 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
490 --- 4.0.10 2010/06/18
492 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
493 result set from a connection. The result set will be on its own
494 thereafter; no operations on it will perform retrievals from a target.
495 Only cached copies are returned.
497 ZOOM C:fix case for HTTP servers responding with Connection:close.
498 Ensure that if there is a current task it is resumed (like fetching
499 more records in a result set) . Bug #3484.
501 PQF parser: use odr_atoi for Odr_int (not atoi)
503 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
504 values that contain any non-digits are treated as string attributes
505 (previously decoding only checked for leading character ([0-9]). PQF
506 encoding: attribute string values are not surrounded by double-quotes.
510 New utility for managing threads - thread_create.h.
512 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
513 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
514 but YAZ' implementation do.
516 Fixes for yaz_cond-functions on Windows 7.
518 DLL export more symbols.
520 zoomsh: show record do NOT render opac.
522 Remove *.la files from Debian and RPM packages.
526 Debian package libyaz-dev depends on libgnutls-dev again (was
527 removed in YAZ 4.0.6, but due to Libtool it is still needed
528 even though yaz-config do not list libgnutls libs).
530 ZOOM: Use only one WRBUF for returning string results for
531 ZOOM_resultset. Reduces memory usage for ZOOM in general.
533 ZOOM: ZOOM_connection do not use a shared pointer to
534 ZOOM_resultset after ZOOM_resultset is destructed by
535 user. Reverts to YAZ 4.0.4 behavior.
539 record-conv: fix problem with at least one XSL conversion -
540 due to probably incorrect usage of XML XSL documents.
544 Fix yaz-config for static mode and the use of SSL (gnutls).
548 Forward decl timeval struct in mutex.h and gettimeofday.h.
550 yaz-config: fix 'static' mode linking.
554 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
555 are wrappers for pthreads or Windows. For Windows these are put in
556 a separate DLL: yaz_cond4.
558 libyaz.la (whole source) is compiled with thread. If thread support
559 is enabled enabled, all source of YAZ is compiled with treading support.
560 This allows core utilities such as yaz_log to use thread facilities.
561 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
562 thread utilities. This commit moves mutex utilities (mutex.c) from
563 libyaz_server.la to libyaz.la.
565 yaz-json-parse displays leading text until error.
569 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
570 patch from Giannis Kosmas.
572 SRU: no longer URL encode SRU database. The URL for an SRU server is
573 a URL and such is alreeady encoded - at least when given with leading
574 http:// or https://. This reverts behavior to YAZ 3.0.50.
576 Support for new MARC XML notation TurboMARC which like MARCXML is a
577 complete representation of MARC/ISO2709.. This one, however, is more
578 compact and allows for faster processing with XSLT. TurboMARC can be
579 used in the marcdisp.h API, from the yaz-marcdump utility and from
582 yaz-ztest can be configured - via the database - to perform certain
583 delays when it performs operations search, present and single record
584 fetch. This allows testers to make yaz-ztest act as a real or even slow
585 Z39.50 server. Refer to the yaz-ztest man pages for details.
589 wrbuf_destroy allows NULL WRBUF passed to it.
591 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
593 Add ZOOM_connection_close.
595 No fixed size buffers for ZOOM shell - bug #3257.
597 tstodr: make it work on s390 platform.
599 New icu iterator-functions. The new icu_iter-functions makes it possible
600 to use ICU chains from many threads.
602 yaz-client: better syntax check for show command.
606 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
609 New simple local-file XML include facility which allows file glob-patterns.
610 Refer to yaz/xml_include.h.
612 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
615 ZOOM_record_get supports new parameter "format" which makes it format XML
618 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
619 JSONText in ECMA-262) is JSONValue, not JSONObject.
623 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
624 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
626 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
627 POSIX/Unix builds .so with major version 4.
629 Remove old LOG_-defines from log.h. They have been obsolete and
630 undefined by default for the last 5 years.
632 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
634 GFS: Remove socket (int *fd) from search_rr handler. The socket
635 descriptor ptr is a facility that allowed a search handler to supply
636 a socket which would serve as a callback - when search was complete.
637 This facility has now been in use for years.
639 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
640 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
641 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
642 returns 'const char *' rather than 'char *. The returned string is
643 read-only and should not be modified by applications. COMSTACK cs_close is
644 now a void function - it no longer returns int. No applications check for
645 the value and the implementations has always returned 0.
647 ZOOM: use size_t for scan hit counts and str size. Functions
648 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
649 occ (hit count) and len (string length) are now of type size_t pointer
650 rather than int pointer. This is to be able to represent large hit counts
651 and to also just to use the proper type for string length (strlen result).
653 New JSON parser. Refer to include/yaz/json.h .
655 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
656 Used to be int in some cases. Many wrbuf_-functions used to return an int
657 indicating some length.. These return values were never used. And so they
660 ODR: odr_malloc, odr_total now takes size_t for size.
662 clone_z_type: fix leak; occurred for encoding failures.
664 --- 3.0.52 2009/12/03
666 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
667 bug was introduced in 3.0.51.
669 --- 3.0.51 2009/12/02
671 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
673 tcpip comstack: fix leak for getaddrinfo.
675 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
676 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
677 Decoding of SRU "path" database is performed by private function
678 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
679 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
681 yaz-client: honor base command for SRU. Change when database setting
682 is applied for SRU and ensure it is kept when a connection is reset.
683 Change also the way errors are displayed or SRU (decoding of packages).
685 --- 3.0.50 2009/11/02
687 Add support for extra request / response data for SRU codecs and GFS.
688 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
689 for extra data response buffer and length. For the GFS, both request
690 and response data (XML) is carried in extra_args and extra_response_data
691 for the search handler. Patch by Ko van der Sloot.
693 ZOOM: For queries that cannot be converted to the specified rpnCharset,
694 ZOOM now returns a diagnostic on the client-side ('invalid query' /
695 10010). This fixes bug #2113.
697 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
698 cmdfile included a 'quit' command that would result in a memory violation.
700 --- 3.0.49 2009/10/01
702 Make a number of functions defined in xmlquery.c static. These have
703 never been declared in a public header file (yaz/xmlquery.h) and was
704 made public by mistake.
706 Improve speed of character conversions (iconv utilities). This makes
707 conversions from MARC-8 faster.
709 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
710 unless type desired is "raw". This will prevent type "xml" from
711 returning ISO2709 .. Which obviously can not be XML parsed.
713 Fix memory leak in ZOOM that would occur if option apdulog was used
714 on a re-used connection.
716 Frontend server logs HTTP requests.
718 Frontend server now sends Z39.50 close when it times out (sesssion has
719 been idle for too long). Versions 2.0.30 and earlier also sent close.
720 But due to a mistake this was disabled in all versions after that, i.e.
721 the server would just close the socket immediately.
723 yaz-client emits a better message when receiving an unrecognised
724 userInformationField.
726 Skip zero-length subfields when decoding ISO2709. This rare case happens
727 if a record has two FS characters in a sequence. Without this patch
728 there would be a reference beyond char array in using_code_len fragments
731 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
733 --- 3.0.48 2009/08/28
735 The show command offered by the zoomsh command now takes a 3d optional
736 parameter type which is what is passed to ZOOM_record. If the type
737 argument is omitted, "render" is used.
739 RPN to CQL conv may use USE string attributes (bug #2978).
741 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
743 --- 3.0.47 2009/07/08
745 Function yaz_xml2query allows a diagnostic element in the PQF XML
746 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
747 code and additional info respectively.
749 The BER BOOLEAN is now the integral type Odr_bool which still happens
750 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
751 typedef'd to Odr_int. This is still an integral 'int', but it may be
752 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
753 ASN-1 compiler as well as programs has been updated to use the new types.
755 --- 3.0.46 2009/06/08
757 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
758 only the bibliographic record was rendered. For type=opac, an OPAC
759 record is only returned if it is present.
761 iconv: small fix for encoding of advancegreek.
763 yaz-client: avoid double display of SRU/SRW records (bug #2798).
765 yaz-client: option auto_reconnect=on really reconnects.
767 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
769 server: avoid null ptr ref for for yaz_poll errors.
771 build: fix RPM build for RHEL 5.3.
773 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
775 --- 3.0.45 2009/03/31
777 Fixed bug #2709: TCP connect returns Invalid argument.
779 Fixed compilation for mingw.
781 Honor charset for raw records (ZOOM_record_get).
783 Fixed use of errno for threaded mode that was seen on Solaris 10.
785 Fixed argument passing with blanks in value for Windows Service.
787 Disable YAZ' own log rotate by default (no 1 GB limit).
788 The variable l_max_size which specifies the log file limit is set to 0
789 (DISABLED): This is due to the fact that YAZ is most often deployed using
790 logrotate. Also YAZ can not perform log rotate because of unsufficient
791 permissions (setuid).
793 --- 3.0.44 2009/02/17
795 List supported encodings in man page for yaz-iconv.
797 Fixed missing SSL libs for --libs output
799 Re-established OID record syntax application-xml. Nobody should use it
800 but we don't want to change soname because of this symbol being absent.
802 --- 3.0.42 2009/02/02
804 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
806 Added member named_result_sets for init handler struct for the GFS. This
807 allows a server to disable named result sets.
809 Removed OID record syntax application-xml.
811 Added support for rule-based transliterator for ICU wrapper of YAZ.
813 Fixed bug #1902: yaz-icu XML output.
815 Make YAZ checks Emacs friendly.
817 BITSTRING value shows value. Bug #2346.
819 ISO2709 decoding: skip control characters from indicator data.
821 Omit sort key by default in yaz-icu's output.
823 Allow combined single char options (again) for YAZ' options function.
825 Utility yaz-marcdump got option to display YAZ version (-V).
827 Allow YAZ to use ICU 3.4.
829 Added new ICU test case which illustrates removal of diacritics.
831 --- 3.0.41 2008/12/29
833 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
835 --- 3.0.40 2008/12/29
837 For configure, using option --without-xml2 also disables Libxslt/Libexslt
840 Fixed bug #2352: yaz-marcdump crashes for certain record.
842 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
844 Added support for Danmarc2 to UTF-8 conversion.
846 Added support for ISO5426 to UTF-8 conversion.
848 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
849 implementation version.
851 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
853 --- 3.0.38 2008/11/10
855 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
856 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
858 ZOOM C now interprets databaseName option for ZOOM connection as path
861 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
863 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
865 Dummy Libxml2 types no longer defined in headers of YAZ'.
867 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
870 --- 3.0.36 2008/09/26
872 Various ODR chapter fixes.
874 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
876 Added missing source for Windows compilation, mutex.c.
878 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
880 For SRU connections in ZOOM all records up to "count" are now fetched.
882 Fixed crash in generic frontend server (and yaz-ztest) which occurred
883 in Windows due to bad error handling for Libxml2.
885 Added facility for sending arbitrary records (ASN.1 any) using
886 ZOOM C's Extended service update. Patch by Sam Reynolds.
888 New options for ZOOM C's connection, logapdu which makes ZOOM log
891 --- 3.0.34 2008/06/18
893 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
895 --- 3.0.32 2008/06/12
897 Fixed memory violation that could occur when decoding UTF-8. This bug
898 was only present in 3.0.30 of YAZ.
900 --- 3.0.30 2008/06/06
902 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
903 GNU TLS is used by default (if found).
905 yaz-ztest returns OPAC records if a client asks for OPAC.
907 Improved speed of MARC-8 encoding.
909 Added support for lossy and loss-less MARC-8 encoding.
911 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
913 Added new Windows Service wrapper (sc).
915 yaz-client's itemorder command may now send a file.
917 Fixed yaz-marcdump to allow the use of NS prefix for record element.
919 Added new function yaz_log_xml_errors.
921 Allow (but warn) unknown XML attributes in MARCXML parsing.
923 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
925 The UTF-8 to MARC-8 conversion now uses a different set of characters
926 for Greek symbols. Bug #2120.
928 --- 3.0.26 2008/02/21
930 Added yaz_daemon (daemon.h).
932 Fixed bug #2068: pkg-config trouble
934 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
936 --- 3.0.24 2008/01/28
938 Document --with-xml2 option.
940 Added OPAC XML XSD (etc/opacxml.xsd).
942 Allow glob mask for name attribute in retrieval element for the
943 generic frontend server's retrieval facility.
945 Changed yaz_poll_poll to return yaz_poll_except for all returned events
946 except POLLIN/POLLOUT.
948 Fixed error handling in cs_listen. Bug #2037.
950 --- 3.0.22 2008/01/20
952 Fixed version in yaz/yaz-version.h.
954 Fixed bug #2027: Crash when closing connection.
956 Changed configure so that ICU support is only enabled if only ICU
957 and Libxml2 is available (because the ICU chain is XML based).
959 --- 3.0.20 2008/01/15
961 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
962 is built. Only this DLL depends on the ICU runtime.
964 yaz-ziffy is no longer part of YAZ. It is distributed separately by
965 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
967 Changed license of CCL module to 'Revised BSD'. After consultation with
968 remaining members of the original EUROPAGATE consortium, we are re-issuing
969 the CCL module without a separate license. The software was developed by
970 Index Data as part of a research project. The special license was included
971 to help feed usage information back to the project consortium to support
972 project evaluation. At this time, the project consortium has long-since
973 disbanded, and the majority of the original principals have retired. At the
974 same time, we have significantly modified the software during the following
975 years, to the point where very practically no original code remains. To
976 simplify re-use of the software, we have contacted those members of the
977 consortium who could be reached, and agreed to re-issue the module as a
978 proper part of the YAZ package.
980 Tcl scripts uses /usr/bin/tclsh as preferred shell.
982 CQL closer to being version 1.2 compliant. CQL also allows free-form
983 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
986 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
987 bug could make Extended services handling crash in the ZOOM layer. This
988 bug was only present in YAZ 3.0.18.
990 --- 3.0.18 2007/12/19
992 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
995 yaz-marcdump reads and writes collection wrapped records.
997 Handle OPAC for record conversion module.
999 Fixes for ICU wrapper.
1001 Allow ICU libs to be controlled with --with-icu .
1003 --- 3.0.16 2007/11/12
1005 Added yaz_poll which is a wrapper for select/poll. When poll is available
1006 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1007 sockets to be in use.
1009 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1010 functionality through an XML based configuration (ICU chain). This system
1011 is useful for search facilities such as Pazpar2 and Zebra that needs to
1012 perform tokenization of indexed material. The ICU code in a separate
1013 library libyaz3_icu.a.
1015 Added HTTP tunnel facility for COMSTACK, bug #1752.
1016 This is a facility that allows a Web proxy, such as squid, to tunnel
1017 Z39.50 traffic. This facility is "transparent" to must applications
1018 using YAZ. It's enabled by using pseudo transport connect: followed by
1019 the proxy address, followed by command, then follwed by he regular
1020 "virtual" addresss. For example,
1021 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1023 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1025 --- 3.0.14 2007/09/21
1027 Fixed bad memory reference in ZOOM_record - cuased by member not being
1028 initialized. This was a problem only in YAZ 3.0.12.
1030 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1031 fields were not removed.
1033 Changed the way C code is generated from codetables.xml. Made a MARC-8
1034 conversion trie for each characterSet section rather than codeTable.
1035 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1036 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1038 --- 3.0.12 2007/09/12
1040 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1041 from ZOOM_record_error).
1043 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1045 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1047 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1049 Better SRW-to-Bib-1 diagnostic mapping.
1051 ZOOM C and yaz-client announces SRU version 1.2 by default.
1053 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1056 Fixed in yaz_sru_decode to allow other version than 1.1.
1058 --- 3.0.10 2007/08/22
1060 Added support for SRU scan for ZOOM.
1062 Added support for the use of the older versions or Extended Service
1063 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1064 set to the version , 1=first, 2=second, 3=third. The third version is
1065 what ZOOM C has used so far. And that, obviously, is the default.
1067 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1068 therefore in Zebra and in SimpleServer-based applications). The new
1069 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1070 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1071 which is passed into the back-end search callback function.
1073 Added support for HTTP Basic authentication in clients: the SRU/W
1074 codec encodes the username/password elements of the PDU structure
1075 appropriately, and these may be set using the "user" and "password"
1076 options in ZOOM-C applications (the same options that are used for
1077 Z39.50 authentication).
1079 --- 3.0.8 2007/06/25
1081 Fixed bug #1208: SSL appears to be broken in ZOOM.
1083 Fixed bug #1206: Libxml2 include path weirdness.
1085 Added oid_name_to_dotstring.
1087 Allow elementSetName to be specified for ZOOM C record update.
1089 Allow waitAction to be specified for ZOOM C based for Extended Services.
1091 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1092 syntax OID. Bug introduced in YAZ 3 series.
1094 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1096 --- 3.0.6 2007/06/06
1098 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1099 directory. yaz-client now reads commands from file given by option -f
1100 if specified; then tries to read .yazclientrc in current directory.
1101 Failing that, it reads .yazclientrc from user's home directory.
1103 Added support for correlationInfo Note and ID for Record Update via
1106 Added yaz-client command querycharset which specifies character set for
1107 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1108 (termListAndStartPoint).
1110 Charset ISO5428:1984 is an alias for ISO5428-1984.
1112 Implemented a way to perform scan in a result set using Z39.50. This
1113 is achieved by attaching the result set name in the characterInfo
1114 (type InternationalString) of OtherInformation in the Scan Request PDU.
1115 The result set is identified in the otherinformation by the new OID:
1116 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1117 This allows for scan in result set and faceted search . Zebra did some
1118 of this in the APT term using attribute type 8 and value being result
1119 set. Using the OtherInformation approach for this is cleaner and easier
1120 to work with in proxies and the like. This facility can be used in
1121 yaz-client using new command setscan which takes a result set as first
1122 argument, start position (APT) as second.
1124 Changed decoding of SRU XML packed records to deal with servers that
1125 have recordData with XML data with multiple root nodes. Also make
1126 comparison for recordPacking case insensitive. Again, one server
1127 returns "XML" where others return "xml".
1129 For SRU responses allow Content-Type application/xml as well as text/xml.
1131 --- 3.0.4 2007/05/21
1133 Fixed bug in character set conversion of BER strings. Bug introduced
1136 --- 3.0.2 2007/05/08
1138 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1140 For OID class, use oid_class consistently.
1142 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1145 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1146 character set for bibliographic information interchange". By Giannis Kosmas.
1148 Added documentation on new OID API.
1150 --- 3.0.0 2007/05/02
1152 Changes to generic frontend server interface: added new member
1153 'query_charset' for bend_initrequest structure. A backend init handler
1154 should set this member to its native character set for query terms.
1155 When defined, the frontend server logic will announce this character set
1156 to a client if the negotiationModel bit is set by the client. All server
1157 implementors are encouraged to specify this. If a backend server does not
1158 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1160 Added CCL utility to remove terms (stop words) from resulting RPN
1161 tree. This is handled by functions with prefix ccl_stop_words_ .
1163 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1164 terms in RPN queries.
1166 Clean-up the CCL API. Moved some internal structures from ccl.h to
1167 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1168 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1169 This is replaced by ccl_parser_find_str which takes a string instead.
1171 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1172 libyaz.la is the core of YAZ except the generic frontend server and
1173 does not depend on POSIX threads anymore. libyaz_server.la is the
1174 generic frontend server facilities and uses POSIX thread functionality
1175 if available. The libyaz.la no longer depends on POSIX threads because
1176 the number of global structures is limited. NMEM no longer re-uses blocks
1177 between threads ; it simply free's memory immediately but allocates in
1178 "large" chunks as usual. We don't expect any performance penalties
1179 because of this. The yaz_log system is still using a global log_level so
1180 caution must be taken when modifying it with yaz_log_init_.. +
1181 yaz_log_mask_str. This, however, should not cause any trouble because
1182 these functions are called during initialization of application code
1183 anyway. `yaz-config --libs server` returns libs for server applications;
1184 `yaz-config --libs` returns libs for non-server applications.
1186 New OID database - with public definitions in oid_db.h. Removed old OID
1187 database including the head oid.h and definitions such as enum oid_value
1188 and struct oident. The new OID database uses the same string names as
1189 before but the 'protocol' is gone. There are now only two representations
1190 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1191 converts from string to OID; functions with prefix yaz_oid_to_string
1192 converts the other way.
1194 Change to emit_term() in CQL-to-PQF query translation: when a term has
1195 the /regexp relation modifier, do not process it for leading and
1196 trailing "^" and "*", which have quite different meanings in regular
1199 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1200 write handlers no longer carries a 'last' parameter. This will make
1201 yaz_iconv flush "less" characters. A flush is performed by call to
1202 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1204 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1205 removed, because function yaz_query_to_wrbuf does the same.
1207 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1208 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1210 Deprecated MARC utility functions removed.
1212 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1215 Branch split: YAZ_2_1_55_branch
1217 --- 2.1.54 2007/03/16
1219 Fix to ZOOM-C so that transparent reconnection is properly handled on
1220 connections that are in asynchronous mode.
1222 Fixed compilation on OpenBSD 4.0.
1224 Large strings in GRS-1 records are now properly displayed in yaz-client.
1226 Added character conversion support for "advancegreek"; based on patch from
1229 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1230 sequence is met. Before the error was not set so it would be unknown.
1232 Adjust yaz-marcdump MARC reader so that it skips until record separator
1235 --- 2.1.52 2007/03/07
1237 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1238 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1239 fd_set structure used as a bitmask for the FDs to be selected on.
1241 Using ACX_PTHREAD macro to check for POSIX threads.
1243 Fixed have-vsnprintf check.
1245 --- 2.1.50 2007/02/23
1247 Fixes for configure on BSD. Bug #900.
1249 Added snprintf/vsnprintf wrappers for systems that don't have
1250 limits (heavens forbid).
1252 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1253 created before all previous tasks were completed and removed from the
1254 task queue, the new task could be removed by a mistake.
1256 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1258 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1260 Fixed bug #832: Problem with MARC/charset in yaz-client.
1262 Fixed bug #668: save command line history for yaz-client.
1264 Fixed bug #830: pkg-config support.
1266 --- 2.1.48 2007/01/23
1268 Extended ZOOM result set options with two options that may be read by
1269 a client: resultSetStatus and presentStatus with values as specified for
1271 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1273 Fixed bug #827: Using SSL fails on Debian etch.
1275 Fixed bug #826: Weird looking chars for set of MARC records.
1277 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1278 that is treated as an ItemOrder with itemRequest being an XML document
1279 external. The value of "doc" is the content.
1281 Extended the GFS search facility. New member of bend_search_rr
1282 'estimated_hit_count' signals that hits is known to be an estmate
1283 (higher or lower than real hit count). New member 'partial_resultset'
1284 signals that the search was partial (hit count is lower or equal than
1285 real hit count). For Z39.50, the information is stored in resultSetStatus
1286 member of SearchResponse APDU. For SRU, the information is signalled
1287 via SRU diagnostic 59: "Result set created with valid partial results
1290 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1292 --- 2.1.46 2007/01/13
1294 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1296 Added ZOOM_connection_peek_event.
1298 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1299 the following new functions:
1300 ZOOM_event_nonblock, ZOOM_connection_process,
1301 ZOOM_connection_get_{socket,mask,timeout},
1302 ZOOM_connection_fire_event_{timeout,socket}.
1303 The existing blocking event handler, ZOOM_event, is a wrapper for the
1304 + blocking ZOOM_event_sys_{poll,select}.
1306 Implemented function ccl_xml_config which parses XML version of CCL
1307 configuration (bug #798).
1309 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1311 Added timings utility (yaz/timing.h)
1313 --- 2.1.44 2007/01/03
1315 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1318 Fixed bug #779: Rotation of apdu.log fails.
1320 Fixed for character set conversions:
1321 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1322 Honor G1 set in MARC-8 decoding.
1324 --- 2.1.42 2006/12/17
1326 Fixed bug #775: char conversion does not handle Alternative UTF-8
1329 Implemented function yaz_marc_read_line which parses MARC line format
1330 records. There is a wealth of formats out there. So far, this function
1331 reads line records produced by yaz_marc_write_line.
1333 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1334 more generic and easier to remember(!) options: -i format and -o format
1335 which specifies input format and output format respectively - where
1336 format is one of "marc", "marcxml", "line", "marcxchange".
1338 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1339 does not print anything except warnings for records.
1341 For yaz-marcdump, added support for MARC split into files (-s) with a given
1344 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1345 spec, at http://www.loc.gov/standards/sru/record-update/
1346 This has changed the binary layout of the following structs:
1347 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1348 bend_update_rr . Patch by Ko van der Sloot.
1350 Added GFS utility function bend_assoc_is_alive which returns 1 if
1351 association is still alive (client is connected); 0 otherwise (client
1352 closed connection). This allows busy servers to stop working for
1355 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1356 been a separate piece of software. This version of ziffy has been modified
1357 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1359 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1361 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1362 Client code may now interrogate options such as "init_opt_sort" to
1363 find out whether the server claims to support various options.
1365 --- 2.1.40 2006/11/27
1367 Added utilities yaz_{set,get}_esn to set/get element set name from
1370 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1371 of YAZ and has been so since YAZ 2.1.10.
1373 Implemented ZOOM_record_error which returns error information for
1374 record (surrogate diagnostic).
1376 --- 2.1.38 2006/10/31
1378 Updates for SRU Update by Ko van der Sloot:
1379 1. Changed name from "operation" to "action"
1380 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1381 versions in the code, marked as 'backward compatible'.
1382 3. Added diagnostics for SRU Update.
1384 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1386 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1388 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1390 For GFS, fixed problem with SRU diagnostic 'First record position out of
1391 range' being issued for 0 hits.
1393 zoomtst10 part of Windows Build.
1395 --- 2.1.36 2006/10/13
1397 Implemented yaz_filepath_comp which splits a path into file path
1398 components (required by Zebra 2.0.3+).
1400 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1401 BSD inspired license until now so this should not have any real impact on
1402 anybody. See http://www.opensource.org/licenses/bsd-license.php
1404 Fixed bug #687: Missing log lines.
1406 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1409 Fixed bug #689: SRU diagnostics to be added.
1411 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1412 whether a connection is idle (no more work do do).
1414 --- 2.1.34 2006/10/04
1416 Change type of optval from long to int for invocation of setsockopt with
1417 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1419 Added support for specifying the max log file size for the Generic
1420 Frontend Server. The size is given with option -r.
1422 --- 2.1.32 2006/09/21
1424 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1426 --- 2.1.30 2006/09/17
1428 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1431 Fixed bug in Generic Frontend Server that could cause a server to stop
1432 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1434 For the generic frontend server, the maximum record size is used as maximum
1435 size of incoming packages (SRU + Z39.50). The value until was previously
1436 only used in Z39.50 Init negotiation and, later, in a session controlled
1437 sizes of records returned. This is controlled using -k option. It can be
1438 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1440 --- 2.1.28 2006/09/04
1442 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1445 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1447 New option for yaz-marcdump -lpos=value which allows setting a portion
1448 of MARC header to a certain value.
1450 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1452 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1453 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1455 --- 2.1.26 2006/08/15
1457 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1460 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1462 --- 2.1.24 2006/08/08
1464 Fixed MARC ISO2709 encoding routines to deal with character set
1467 Minor changes to GFS logging. Database included in search request log
1470 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1471 cached/multiple records.
1473 Shared libraries are built by default on Unix+configure.
1475 Changed cql2pqf transformation to use a different evaluation order. The
1476 new order is: always, relation, structure, position, truncation, index
1477 and relationModifier. Old order was: always, relation, relationModifier,
1478 structure, index, position, truncation. Note that the the latter ones
1479 override former ones for identical attributes.. The new scheme means that
1480 it is possible to override any existing attribute with a relationModifier.
1481 And also that it is possible to override everything for the index rule
1482 (except the ones listed in relationModifier). No order is perfect but this
1483 one, we believe, covers more real cases.. The "always" should have been
1484 called "default", since the attributes there can be overridden with all
1487 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1488 compilation phase, but also for yaz-config --cflags output. This allows
1489 us to have public headers with Libxml2 stuff in them . It should also,
1490 eventually, make Libxml2 checks redundant in packages using YAZ, such
1493 --- 2.1.22 2006/06/15
1495 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1496 stored in uri, message and details.. Previously diagnostics were stored
1497 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1498 compatibility.. but he's probably the only one affected, so.
1500 Added support for CCL, compiled on the client side, in ZOOM-C. This
1501 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1502 input; the resulting query objects can be used for for searching with
1503 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1505 YAZ' configure searches for OpenSSL by default.
1507 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1508 SL_CTX_use_certificate_file. See
1509 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1510 for more info. Thanks to Ko van der Sloot.
1512 --- 2.1.20 2006/06/02
1514 Bug #600: SRU GET, POST support for yaz-client. Introduced
1515 command 'sru' which selects method SOAP/GET/POST.
1517 Allow missingValueAction to be specified for the sortspec string -
1518 function yaz_sort_spec. By default, the missing value action is null.
1519 Use ! to specify "abort". Use = followed by stringvalue to specify default
1522 Ensured that Present-handler (if defined) is called in GFS before any call to
1523 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1524 searchRetrieve requests.
1526 Documentation for YAZ is now based on the Docbook XML/XSLT using
1527 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1528 is no longer depending on jade/openjade or docbook-to-man scripts.
1529 PDF is no longer part of the distribution - but can optionally be
1530 made using DSSSL/jadetex or FOP.
1532 Added retrieval handling support in Generic Frontend Server to support
1533 conversion between MARC/XML as well as XSLTtransforms. See
1534 etc/yazgfs.xml for an example.
1536 Added Authentication support to Generic Frontend Server in SRU
1537 mode. Authentication using HTTP Basic is supported, as is the use
1538 of 'x-username' and 'x-password' parameters in the request itself.
1540 Added support for a new character set MARC8s identical to MARC8 except
1541 that it converts combined characters to single Unicode characters in the
1542 Latin-1 range (when possible).
1544 --- 2.1.18 2006/04/24
1546 ASN.1 compiler 0.4: generates brief Doxygen file header for
1547 generated .h/.c files.
1549 Utility yaz_iconv now supports conversion to MARC-8.
1551 New facilities for the MARC module. The reading - and writing of
1552 content are separate methods for the yaz_marc_t handle. The following
1553 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1554 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1555 format). Write functions have prefix yaz_marc_write_.. The existing
1556 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1557 available. Removed support for OAI-MARC and simplexml (not the
1558 simplexml from PHP5).
1560 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1561 to be returned for this connection.
1563 --- 2.1.16 2006/03/31
1565 Allow multiple languages and charsets to be specified with
1566 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1567 negcharset iso-8859-1,utf-8
1569 Translation of proximity nodes from CQL into PQF now works.
1571 Moved to automake 1.8, 1.9.
1573 Added function yaz_log_set_handler which allows a log handler to be
1574 installed. This handler will be called for all log messages. Output
1575 to file is also produced; but that can be disabled by passing NULL
1576 fname to yaz_log_init_file.
1578 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1580 For SRW (including GFS), accept application/soap+xml as content-type
1583 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1584 produces NO stylesheet reference even if a default stylesheet is specified
1587 --- 2.1.14 2006/03/14
1589 Updated Windows package to include yazd.dll + yazd.lib for the
1590 Development component.
1592 If the environment variable YAZ_LOG is set, then it is used as a
1593 string indicating the default level of logging to use if not
1594 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1595 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1596 used as before. So, for example, to omit warnings from YAZ logging,
1597 export YAZ_LOG=-warn
1599 cql_transform() now map structure and other attributes before indexes,
1600 so that index-specific structures and other attributes can override
1601 defaults. So now a combination of mapping specifications such as:
1603 index.dc.date = 1=date-modified 4=5
1604 does the right thing.
1606 cql_transform() now also respects the "always" mapping specification,
1607 which establishes an initial set of attributes to be used for all
1608 terms except where overridden by more specific attributes associated
1609 with the index, relation or modifier.
1611 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1612 which mode to use; one of "post", "get" or "soap" (SRW, default).
1614 Fixes for yaz_iconv routines: changed trie-based character set conversions
1615 to use only non-negative values for bit fields due to Sun's C compiler not
1616 supporting negative values.
1618 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1619 sequences where not read correctly. Fix by Rustam Usmanov.
1621 Updated win/makefile to use options, settings which makes things
1622 compile with VS C 2005.
1624 --- 2.1.12 2006/02/01
1626 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1628 In ZOOM socket code, use select instead of poll on MacOSX.
1630 ZOOM-C now support client-side compilation of CQL into RPN that is
1631 sent to the server, enabling CQL to be used against all Z39.50
1632 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1633 ZOOM_query object, and submit it using ZOOM_connection_search().
1634 The CQL-to-RPN translation uses a configuration file, the name of
1635 which must be specified in the Connection's "cqlfile" option.
1637 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1638 function, which takes as its start-term parameter a ZOOM_query object
1639 (which may have had either CQL or RPN set into it).
1642 --- 2.1.10 2005/11/29
1644 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1645 GFS to support this as well. Backend handler, bend_srw_update, does the
1646 update work. Code contributed by Ko van der Sloot.
1648 Allow retrieval of Search Result-1 information in ZOOM by the use of
1649 options that are attached to a result set. ZOOM documentation updated
1652 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1653 UTF-8 conversion. Patch by Raj Patel.
1655 Added option -m to GFS to control formatting of timestamps in log file.
1657 Added 'exit' as synonym for 'quit' in yaz-client
1659 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1660 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1661 for the new members. Patch by Ko van der Sloot.
1663 Added support for SRU POST. It is supported for content-type
1664 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1666 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1667 Instead make the library libyaz.la multi-threaded. Threading as a whole
1668 can still be disabled by configure option --disable-threads. Previosly,
1669 with older GLIBCs there were problems with MT libs under Apache. This
1670 has now been fixed a long time ago.
1672 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1675 CQL module modified to be case insensitive for relations/indexes/operations.
1677 Fixed bug in CQL transform code: incorrect value relationModifieder
1680 Added 'show all' command for yaz-client which retrieves all results
1683 Added new yaz-client, xmles, which takes a (private) OID and
1684 a document to be sent as an extended service request.
1686 Describe new yaz-client commands wait_response and set_auto_wait.
1688 Increase TCP/IP listener backlog from 3 (which I am guessing was
1689 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1690 that the socket will queue as many incoming connections as it's able
1691 to handle ongoing connections. In other words, it will never now
1692 refuse a connection that it would be able to handle merely because
1693 it's not got around to accepting() enough of the pending connections
1694 yet. This is the behaviour anyway under Linux, where the listen()
1695 argument is ignored; but not under BSD and on systems such as
1696 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1697 YAZ-based servers should now be uniform across operating systems in
1700 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1701 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1702 This allows yaz-marcdump to read large MARC batches (>2 GB).
1704 Modified all YAZ source files - except the source which is auto-generated
1705 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1708 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1709 corresponding to the existing *_setl() function. These allow option
1710 values containing arbitrary valuues.
1712 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1713 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1714 except that it returns an indicator of whether or not the sort
1715 criterion was accepted (0 for OK, -1 for invalid).
1717 --- 2.1.8 2005/06/07
1719 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1720 MARC output rather than returning "new" buffer.
1722 yaz-client warns about unknown init options.
1724 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1726 --- 2.1.6 2005/05/24
1728 Added support for SRW sort in Generic Frontend Server. Patch
1729 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1730 sortKeys - or NULL if none is provided.
1732 Fixed bug #307: It was impossible to specify indefinite/no timeout
1733 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1736 Added support for multiple languages and charsets to be specified in
1737 ZOOM. Each charset/language is separated by a blank. If negotiation is
1738 in effect in init-response, Option
1739 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1740 Code based on patch by Vasiliy Osadchuk.
1742 Fixed bug #306: infinite recursion that occurred when calling
1743 yaz_log_level_init as the first call (before other log level or
1746 Fixed bug in scan handling in front end server: if preferred-Position-In-
1747 Response was non-present, a NULL pointer referece was performed.
1749 --- 2.1.4 2005/04/26
1751 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1752 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1753 now defined for all those error codes. So instead of putting 109 in
1754 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1755 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1757 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1760 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1762 Program yaz-client now exits and produces an error message if multiple
1763 Z39.50 servers are specified on the command line (none or one allowed
1766 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1769 --- 2.1.2 2005/03/16
1771 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1773 Fixed bug #272: Preserve spacing for CCL terms.
1775 --- 2.1.0 2005/03/14
1777 Added support for virtual hosts and multiple backend servers for
1778 the YAZ frontend server. The configution is XML based and
1779 support specificition of CQL to RPN mappings and explain information.
1780 See section "Virtual Hosts" in the YAZ manual.
1782 Extended OPAC display utility. OPAC display utility renders
1783 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1784 to supplement yaz_marc_decode_wrbuf.
1786 Fixed a bug in MARC decoder that could caused it to crash for some
1787 invalid MARC records. More diagnostics and warnings where added in
1788 XML output (warnings, etc are stored in comments).
1790 --- 2.0.34 2005/02/08
1792 Fixes for UNIX domain sockets. Bug #261.
1794 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1796 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1797 Added yaz_marc_subfield_str which defines subfield lead string which is
1798 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1799 yaz_marc_endline_str which defines end of fields string used in
1800 YAZ_MARC_LINE format. Default string is newline.
1802 Experimental support for MarcXChange. This format can be produced
1803 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1804 http://www.bs.dk/standards/MarcXchange.xsd
1806 Added yaz-client commands scansize that sets maximum number of
1807 entries to be returned by scan.
1809 --- 2.0.32 2005/01/11
1811 Added support for SRW scan in yaz-client and Generic Frontend Server.
1813 * Added whereInList member to SRW Scan Term.
1815 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1817 Fixed NMEM system to return aligned blocks on the smallest boundaries
1818 that are suitably aligned for all possible types on the particular
1819 architecture YAZ is being built for.
1821 --- 2.0.30 2005/01/04
1823 Fixed numerious warnings that was issued with newer versions of GCC.
1825 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1826 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1829 Make YAZ Generic Frontend Server slightly faster.
1831 Enhance (and reduce) logging for Generic Frontend Server.
1833 Revert YAZ log system so that it flushes every write operation
1834 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1836 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1837 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1838 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1839 will effectively disable old definitions.
1841 --- 2.0.28 2004/11/09
1843 Added yaz_log_time_format which specifies log format using
1846 Added yaz_log_module_level which returns mask for a module. Value
1847 is non-zero mask a if module is enabled; zero if disabled.
1849 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1850 in include/yaz/cql.h.
1852 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1854 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1856 Fixed bug #172: RPM builds does not enable SSL.
1858 Doxyfile.in part of dist. Doxyfile generated by configure.
1860 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1861 are given and the corresponding component does not exist.
1863 Extend CCL documentation in YAZ reference. Describe r=r.
1865 --- 2.0.26 2004/10/01
1867 Fixed MARC->MARCXML conversion to properly deal with
1868 fields, subfields, indicators having non-ASCII characters.
1870 Fixed MARC->MARCXML conversion so that ASCII control characters
1871 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1874 Added YAZ GFS support for conversion from Z39.50 surrogate
1875 diagnostics to SRW surrogate diagnostics.
1877 Bug fix: YAZ GFS did not return schema in explainResponse.
1879 --- 2.0.25 2004/09/30
1881 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1882 now converts recordSchema to elementSetName as well as schema URI.
1884 Fixed bug in COMSTACK that prevented HTTP request packages from being
1887 --- 2.0.24 2004/09/29
1889 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1890 does not require white-space before and after the dash in a range, e.g.
1891 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1894 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1895 due to new GCC removing "redundant" code.
1897 Added yaz-client commands scanpos and scanstep that sets preferred
1898 position and step-size for scan.
1900 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1902 Added CCL utility ccl_qual_buf which parses one or more CCL
1903 spec lines in a buffer.
1905 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1906 of name and value - ignoring empty lines and comments.
1908 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1910 Added odr_get_element_path which returns current element path for an
1911 ODR handle. This utility is useful in error handling or user-defined
1914 Added ODR_PRINT utility odr_set_stream which is is a more generic
1915 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1916 to a write function and pointer to close function. The close function - if
1917 non-NULL - will be called during odr_destroy.
1919 Fixed bug in CCL parser where truncation char was not removed from
1920 right side when truncation=both was in effect.
1922 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1925 --- 2.0.23 2004/08/11
1927 Fix buffer overrun in CQL parser when dealing with proximity (%).
1929 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1930 to UTF-8/UCS conversion is now only based on codetables.xml.
1932 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1934 --- 2.0.22 2004/08/06
1936 Add support for more "commit changes" in ZOOM (uses Extended Services).
1938 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1941 Yet another small fix for configure of SSL.
1943 --- 2.0.21 2004/05/14
1945 Fix SSL libs for configure when --with-openssl=DIR is given.
1947 --- 2.0.20 2004/05/10
1949 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1951 SSL comstack now uses yaz.pem certificate file on server side
1952 by default. Certificate filename can be configured by calling
1953 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1955 Fix bug regarding multiple calls to ZOOM_connection_connect.
1957 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1959 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1960 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1962 ZOOM now allows inspection of X509 peer certificate for verification.
1963 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1965 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1966 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1967 as "modular" but it simplifies things.
1969 Added cs_get_peer_certificate to that returns peer X509 PEM.
1971 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1972 NULL if SSL is unavailable.
1974 Documentation about MARC decoding tools.
1976 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1978 --- 2.0.19 2004/03/30
1980 Rename CHANGELOG to NEWS to follow GNU style packing.
1982 Fix bug with missing initialization of member in init_diagnostics.
1983 This bug affects threaded version of GFS server.
1985 --- 2.0.18 2004/03/20
1987 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1990 Ensure zlib.dll is packed with Windows install.
1992 --- 2.0.17 2004/03/17
1994 Fix encoding of xsd:string to use text instead of CDATA.
1996 Fix endless loop in CQL parser with unbalanced ".
1998 Use a more compact way to store MARC-8 conversion tables.
2000 --- 2.0.16 2004/03/16 Debian only
2002 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2005 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2010 --- 2.0.15 2004/03/01
2012 Another fix for decoding of XML packed records.
2014 --- 2.0.14 2004/02/25
2016 Fixes for Chunked encoding. White space not ignored after length spec.
2018 Update NS and use default NS for SRW diagnostic elements.
2020 --- 2.0.13 2004/02/23
2022 Implement ZOOM_resultset_cache_reset which resets record cache.
2024 Implement ZOOM_resultset_sort which sorts a result set.
2026 Implement chunked HTTP transfer.
2028 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2030 --- 2.0.12 2004/02/16
2032 Added member 'schema' to bend_explain_rr structure so that backend
2033 can specify explain record identifier. Defaults to Zeerex 2.0.
2035 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2037 --- 2.0.11 2004/02/16
2039 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2042 Added init command for yaz-client which sends "extra" init request.
2044 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2045 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2047 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2049 Make ZOOM error code for "invalid query".
2051 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2053 --- 2.0.10 2004/02/05
2055 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2058 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2060 Added option -p <file> to make Generic Frontend Server to write PID file.
2062 Added option -D to put Generic Frontend Server in background on its own.
2064 Make ZOOM C recognize option "password". If unset, "pass" is used
2065 (for backwards compatibility).
2067 Fixed a bug in Generic Frontend Server that could make it crash if a
2068 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2071 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2072 Must be issued before open, in order to be in effect.
2074 --- 2.0.9-6 2004/01/12 Debian/Windows
2076 Make the SRU server more picky WRT unknown params, etc.
2078 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2080 New YAZ client command, options, that sets Z39.50 options.
2082 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2083 options from a string of tokens (one token for each option bit).
2085 Update SRW diagnostic code messages.
2087 --- 2.0.9-5 2004/01/07 Debian/Windows
2089 Handle user defined stylesheet for SRW/SRU.
2091 --- 2.0.9-4 2004/01/06 Debian/Windows
2093 Fix bug in decoding of Content-Length.
2095 --- 2.0.9-3 2004/01/06 Debian/Windows
2097 Fix a bug with decoding of XML packed records.
2099 --- 2.0.9-2 2004/01/05 Debian only
2101 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2103 Fix bug in SRW/SRU diagnostics decoding.
2105 --- 2.0.9 2004/01/05
2107 Fixed bug in Generic Frontend Server which could drop records exceeding
2108 preferred message size. Reported and fixed by Irina Dijour.
2110 Fixed calculation of package size for structured records in Generic
2111 Frontend Server. Reported and fixed by Irina Dijour.
2113 Fixed namespace for SRW/SRU diagnostics.
2115 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2117 --- 2.0.8 2003/12/22
2119 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2120 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2123 CQL changes to reflect recent changes to the specification:
2124 * Documentation talks about context sets instead of index sets.
2125 * Documentation talks about indexes instead of qualifiers.
2126 * The CQL-to-PQF transformer's configuration file now uses
2127 "index.set.name = <attributes>" instead of the old form
2128 "qualifier.set.name = <attributes>". (Both forms are still
2129 understood but the latter is deprecated.)
2130 * CQL terms with no explicit index specified are now interpreted as
2131 cql.serverChoice instead of srw.serverChoice (which of course
2132 behaves exactly the same.)
2134 --- 2.0.7 2003/12/16
2136 MARC conversion can now generate ISO2709 output in another
2137 character set. yaz-marcdump uses this facility if you invoke it
2140 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2141 functions from there can be used from C++.
2143 --- 2.0.6 2003/12/04
2145 Frontend server now transfers memory from decoded packages to stream
2148 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2149 references to show up.
2151 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2152 the ZOOM Abstract API. The older names for the same options are still
2153 also supported for the benefit of old applications.
2155 ZOOM-C supports "implementationId" and "implementationVersion" options
2156 to go along with "implementationName". These allow the user code to
2157 specify identification strings to be sent to servers.
2158 Add OID for the new ExtLite attribute set.
2160 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2161 as requested/supplid by Ere Maijala <ere@atp.fi>
2163 For generic frontend server, reverse the order of
2164 "toolkit-supplied / application-supplied" strings sent as implementationId,
2165 Name and Version. Also, remove the spaces around the slash. This brings
2166 the GFS in line with the behaviour of ZOOM-C on the client side.
2168 Add function ZOOM_scanset_display_term.
2170 yaz-client shows scan displayTerm if present.
2172 Utility yaz-iconv is now installed by default along with the man page
2175 Extend configure check for OpenSSL to use pkg-config where available (such
2178 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2179 server to specify uid/gid/mask for socket using the format
2180 unix:[user=uid,][group=gid,][umask=mask,]file=path
2181 If file= is omitted the existing format is assumed, e.g.
2183 in which case the mask is 0666 (rw for everybody).
2185 Major restructure of YAZ source. All source in libyaz is in src directory.
2186 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2187 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2189 Added man page for utility yaz-marcdump (used to be called marcdump).
2190 yaz-marcdump is installed by 'make install'.
2192 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2193 of incoming package failed.
2195 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2197 Change prototype of odr_perror: add const to message string.
2199 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2201 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2202 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2203 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2204 DNS lookup. There should not be any compatibility problems with this
2205 assuming that blocking=1 or 0 is used.
2207 Fix bad reference in UNIX comstack in function cs_addrstr.
2209 Fix for compilation on AIX.
2211 The generic front-end server (server/seshigh.c) now supports returning
2212 Init diagnostics to the client in User-information-field, in
2213 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2216 --- 2.0.4 2003/09/04
2218 Allow any CQL relation (not just all,any,exact,scr).
2220 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2221 that features the same UI.
2223 Implemented command update0 in YAZ client which is equivalent to
2224 update but uses old of Ext Update ASN.1.
2226 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2227 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2228 Previously no OID was used for this info.
2230 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2231 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2232 returns 'malformed search term' otherwise.
2234 SortResponse member resultCount now set to NULL in sort handler of
2237 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2240 Add three new utility functions for translating OIDs between various
2241 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2242 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2243 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2244 char *oid_to_dotstring(const int *oid, char *oidbuf);
2245 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2247 Reverted modifications for ES Update definition for z_IU0Update
2248 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2249 is back to YAZ 2.0.2.
2251 String value attributes for CCL parser.
2253 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2254 which their FirstSearch server returns in Init responses, sometimes
2255 carrying useful diagnostic information when Init fails. This has the
2256 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2257 "z39.50/oclcui.asn", where its definition is somewhat different from
2258 what OCLC document on their web-site, as required to interoperate with
2261 Support for anonymous authentication in yaz-client. Use the command
2264 * Fix the OID of the Index Data-local "admin" Extended Service from
2265 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2266 the 1000, which indicates a locally-defined OID, was a mistake.
2268 --- 2.0.3 2003/06/20
2270 Fix CCL directive @case handling so that it affects string match for
2271 both CCL keywords and qualifiers.
2273 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2274 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2275 Decoder has been updated with ASN.1 changes as listed in
2276 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2277 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2278 z_IUUpdate, remains unchanged.
2280 ZOOM_record_get may now return a record in a specific character set.
2281 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2282 "from" is the character set of record as returned by target. "to" is
2283 the character set to be returned. If omitted, "to" is UTF-8.
2285 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2287 New ODR utility, odr_getelement, which returns name of element for
2288 which encoding/decoding failed.
2290 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2291 in cases where a required element was omitted.
2293 Bug fix: some MARC8 sequences were not converted.
2295 New ZOOM option "step" which specifies number of records to be
2296 retrieved in one chunk. Used in conjunction with "start" and "count".
2298 SRW support for yaz-client. Use scheme http: to use it, e.g.
2301 yaz-client no longer does (un)intelligent character set conversions
2302 by default. Can be enabled with charset and marc_charset commands.
2304 xmalloc trace fix for 64-bit systems such as DEC alpha.
2306 Solaris 2.6 compile fix.
2308 New function, cql_strerror() translates SRW error codes, as returned
2309 by cql_transform_error(), into human-readable English strings. Used
2310 in yaz-client diagnostics when appropriate.
2312 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2313 converts it into a type-1 query which is sent to the server. This
2314 makes CQL available for use with all Z-servers, as opposed to the tiny
2315 minority that can handle CQL queries themselves.
2317 --- 2.0.2 2003/04/28
2319 New Debian package layout similar to the Redhat Package layout.
2321 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2322 and search result respectively.
2324 --- 2.0.1 2003/04/25
2326 Redhat package is now several packages: libyaz (runtime libraries),
2327 libyaz-devel (development and documentation, and yaz (utility programs).
2328 Package spec file by Morten Bogeskov.
2330 New member 'schema' in struct bend_fetch_rr which the name of requested
2331 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2332 handler MAY set this to reflect the schema of the returned record.
2334 New member 'display_term' in struct scan_entry. GFS now sets member entries
2335 and allocates scan entries to be filled by user scan handler. In previous
2336 version, entries member was allocated by the scan handler. That still works,
2337 but the GFS will ignore member display_term - assuming it was NOT set by
2338 the handler. The fact that the GFS now allocates the entries both allows
2339 for new members and makes a scan handler easier to write.
2341 Fix CQL lex buffer overflow.
2343 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2344 SRU default recordPacking is string.
2346 SRU protocol support for frontend server.
2348 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2350 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2352 Added scan for the ZOOM shell (zoomsh).
2356 * String Identifers for Schemas (Amendment 5).
2357 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2358 Old definition for schema
2359 Odr_oid *schema; /* OPT */
2364 Z_InternationalString *uri;
2365 #define Z_Schema_oid 1
2366 #define Z_Schema_uri 2
2369 * resultCount parameter to Sort Response (Amendment 1).
2370 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2372 Support for SRW 1.0 over HTTP. This is an optional feature and
2373 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2376 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2377 on the same port. SRW SearchRetrieveRequests are mapped
2378 to bend_init,bend_search,bend_fetch,bend_close.
2380 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2382 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2383 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2385 ZOOM connections are SRW based if schem http is used for hostname
2386 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2387 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2389 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2390 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2391 distance=n, order=true/false, relation=le, prox unit=word. If
2392 n is omitted, distance 1 is used.
2394 Fixed problem with C compiler include path in wrong order.
2396 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2397 on Solaris. Patch from Ko van der Sloot.
2399 New MARC decode API. All new functions operate on a yaz_marc_t
2400 handle. The most important new functions are: yaz_marc_create,
2401 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2402 decode and destroy respectively. Decoder can produce formats
2403 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2404 include/yaz/marcdisp.h.
2406 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2407 to UTF-8, UCS-32, wchar_t or Latin-1.
2409 * Prototypes for yaz_iconv_-functions moved to separate header
2410 include/yaz/yaz-iconv.h.
2412 Make a few private functions 'static' in unix.c. This prevents
2413 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2415 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2416 are set when Init Response is received.
2418 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2419 but returns diagnostic set as well.
2421 New function yaz_strerror which is a portable wrapper for
2422 strerror/strerror_r/GetLastMessage.
2424 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2425 is returned for MARC. If type is "oai", then OAI MARC is returned.
2427 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2430 --- 1.9.2 2002/11/26
2432 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2434 Fix bad race conditions on SIGTERM and terminate gracefully in
2437 Move retrieval (data1) module to Zebra since nobody seems to be
2440 Add GRS-1 render for ZOOM using same format as yaz-client.
2442 --- 1.9.1 2002/10/05
2444 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2446 Fix broken ESpec handling in data1 module.
2448 SGML reader parses comments and makes them part of the data1 tree.
2450 Added several type casts so that YAZ compiles as C++ code.
2452 ZOOM didn't handle PDU encoding failures properly.
2454 Added more Bib-1 diagnostics (approved extensions).
2456 GNU configure: better check for iconv.
2458 More portable use of accept, getpeername. Check for socklen_t. Use
2459 int/size_t if socklen_t is not defined.
2463 PQF parser rejects bad queries - including those with extra
2464 characters in them. PQF parser used to silently ignore that.
2465 Cleaner API for PQF added, which allows you to get detailed
2466 error information for bad queries (see yaz/pquery.h).
2468 Fixed bug in ZOOM_record_get for type "database".
2470 Implemented mini iconv library supporting conversions between
2471 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2473 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2475 --- 1.8.9 2002/08/20
2477 Fixed ZOOM C record cache so that preferredRecordSyntax and
2478 elementSetName is used to check for already fetched records.
2480 --- 1.8.8 2002/08/02
2482 Added three members in bend_initrequest structure to facilitate
2483 character set negotiation.
2485 Fixed a bug in frontend server that could cause indefinite
2486 loops under rare conditions.
2488 Revised character set utilities (charneg.h) so that encoding
2489 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2491 For PQF, directive @term <type> sets term type for Scan/Search.
2492 Here <type> is general, string, numeric, null. The term type
2493 is inherited - just like @attr.
2495 New call odr_set_charset that sets character set conversion for
2496 international-strings on a ODR stream. Prototype is:
2497 int odr_set_charset(ODR o, const char *to, const char *from);
2498 The InternationalString is still represented as C string in YAZ
2499 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2500 won't). On the protocol level, you can use any encoding.
2502 Support for UNIX sockets in ZOOM.
2504 Solaris recv sometimes returns errno == ENOENT. It is treated as
2505 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2507 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2508 both client and server. Code by Morten Bogeskov.
2510 --- 1.8.7 2002/05/22
2512 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2513 that they can be used directly from Visual Basic. You must recompile
2514 your windows APP if you're using ZOOM.
2516 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2517 Commands "lang" and "charset" sets language and character set respectively.
2518 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2519 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2521 Attributes from multiple CCL fields may be OR'ed rather than merged
2522 using directive "@field or". Fields are still merged by default -
2523 equivalent to "@field merge".
2525 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2528 Fixed bug in zget for parameter ExtendedServicesResponse.
2532 --- 1.8.6 2002/03/25
2534 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2536 Client displays USR.1:SearchResult-1 (hits per term).
2538 Additional Search Info for search in Generic Frontend Server.
2540 Fixed CCL parsing of "field=s".
2542 WIN32 installer - using the excellent NSIS software from nullsoft.
2544 Fixed CCL parsing of "field = - <number>".
2546 Added function yaz_marc_decode that decodes MARC for line mode
2547 display or XML (similar to that used by JZKit).
2549 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2550 Z39.50. But ISO/ILL was, however.
2552 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2553 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2556 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2558 --- 1.8.5 2002/02/03
2560 New YAZ client features: Command completion and new commands:
2561 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2562 Code provided by Jacob Poulsen.
2564 New call oid_trav, that visits all registered OIDs via callback.
2566 Function ZOOM_record_get now returns const char pointer rather than
2567 void pointer. It saves a lot of type casts.
2569 For YAZ client, command "auth" now allows you to set authentication
2570 in IdPass style. It is enabled when three tokens are given - order
2571 is user, group and password.
2573 Fix memory leaks in MARC record handling for ZOOM.
2575 New option for YAZ client, -k <kilobytes> that sets
2576 maximum record size. Similar to -k option for generic frontend
2577 server and yaz-ztest.
2579 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2581 Prefix query parser reports "fail" when bad attribute set is given.
2583 Fix in MARC decoder. Proximity logging. Fix for attribute set
2584 in scan handler for server. Patches by Shigeru Ishida.
2586 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2589 Configure option --with-openssl=<dir> now works when a directory is
2590 specified. Patch provided by Morten Bogeskov.
2592 New option for YAZ client, -u <auth>, that sets authentication.
2594 ZOOM fix: error information was sometimes "missing", since error
2595 was cleared/reset too when it shouldn't.
2597 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2599 --- 1.8.4 2002/01/04
2601 Scan for ZOOM API. New object ZOOM_scanset. New functions
2602 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2603 ZOOM_scanset_destroy.
2605 New ZOOM function, ZOOM_connection_last_event, that returns type
2606 of last event (such as "receive data", "send data", "apdu received",
2609 New ZOOM option, schema, that specifies schema for retrieval.
2611 New CCL feature. Qualifiers can be aliases for one or more
2612 other qualifiers (if more than one is given, OR is used).
2614 ZOOM uses named result sets if target supports it.
2616 Two new YAZ client commands: . (dot, which sources a script of YAZ
2617 client commands), and ! (to execute shell command.). Implemented
2620 Working on Debian packages.
2622 --- 1.8.3 2001/11/19
2624 YAZ client enables named result sets only if target supports it.
2626 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2628 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2629 with key="host" to get same result.
2631 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2632 Function Z3950_resultset_record(s) returns references to records
2633 "owned" by resultset. To become owner use Z3950_record_clone.
2635 Function z_ext_record handles Extended Services. Thanks to
2638 --- 1.8.2 2001/11/12
2640 CCL Parser fix: ignore token comma when dealing with and-lists.
2642 Documentation updates for COMSTACK.
2644 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2645 Changed prototype Z3950_records. For some functions, int parameters
2646 were changed to size_t.
2648 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2651 New MARC decode/display function, marc_display_exl, which properly rejects
2652 non-ISO2709 records. YAZ client uses it.
2654 --- 1.8.1 2001/10/29
2656 Fix bug: local attribute set wasn't set correctly in PQF strings.
2660 * Old Z39.50 codecs no longer supported.
2662 Added ZOOM C binding. See http://zoom.z3950.org/
2664 Renamed states for COMSTACKs to avoid confusion with events.
2666 Implemented cs_look and proper cs_rcvconnect.
2668 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2670 Configure detects POSIX threads on OpenBSD.
2672 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2673 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2675 When error is returned from present handler, non-surrogate diagnostic
2676 is returned in present response (and fetch handler is no longer called).
2678 * Minor adjustments to pquery parser (PQF). Token characters may be
2679 escaped by using backslash (C-style).
2681 PQF parser allows string attribute values to be specified. For @attr,
2682 non-numeric characters after the equal-sign are treated as strings
2683 (e.g. @attr 9=title).
2685 CCL trunction character may be defined (@truncation in file)
2687 * function zget_ExtendedServicesRequest sets waitAction to
2688 waitIfPossible (was wait).
2690 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2693 CCL operator names may be set in field definition files (CCL_bibset).
2694 See ccl/bib1 for an example.
2696 Fixes in ASN.1 compiler for C++ compatibility.
2698 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2699 and "op_or" to avoid conflict with C++.
2701 Fixed problem with GNU readline detection on Redhat 7.0.
2703 Added step-size for Scan backend handler.
2705 Fixed bug that made the frontend server crash when no attribute
2706 set was specified for scan.
2708 Front-end server automatically switches to original working directory
2709 when installed as an NT service. Previously -w had to be specified to
2712 Added extended attributes for retrieval module (data1), so that data1
2713 records carry d1_readXML/SGML attributes. d1_read also supports
2714 null-data rules ( <tag/>)
2716 On UNIX when POSIX threads are available, a separate library libyazthread
2717 is created. Programmers should link with that library and the yaz library
2718 when using threads. The reason for the split was that some applications
2719 on Linux, such as Apache, doesn't work well when using shared objects that
2722 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2723 (or any frontend server) in SSL mode by specifying ssl: followed by
2724 address. Only tested on UNIX.
2726 Added feature for CCL module. Virtual structure s=al or s=ol generates
2727 and-list and or-list respectively instead of phrase search.
2731 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2732 log_mask_str. This was done to avoid name conflicts with other libraries
2733 (such as other PHP extensions).
2735 Added raw OID member for preferred record syntax (request_format_raw)
2736 and returned record syntax (output_format_raw) for backend fetch method.
2738 Config file yaz-config now accepts options so that it returns specific
2739 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2741 Shared library support for UNIX using GNU libtool.
2743 * Modified backend interface. Request/Response struct's replaced by
2744 one read/write C struct. For example bend_fetchrequest and
2745 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2746 Every handler - even search has to be registered in bend_init
2747 handler. This means that the YAZ library no longer refers to
2748 external functions and it makes it possible to make the whole
2749 thing a single DLL/SO.
2751 Added Segment handler for backend server.
2753 Added Zmbol/Zebra administrative functions to YAZ client.
2755 Threaded frontend server on UNIX (when POSIX Threads are available).
2756 Starting the server with option -T enables multi-threading.
2760 Added configure option --enable-comp/disable-comp to control use
2761 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2762 located in sub directory asn.
2764 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2765 in ${exec_prefix}/bin along with the other programs yaz-client and
2768 GNU automake used to maintain makefiles.
2770 Added several OID's.
2772 Changed retrieval module so that we can load records with no abstract
2773 syntax defined. Tagpaths in these records are fully composed of string
2776 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2780 On UNIX, the generated makefile now supports a proper 'make install'.
2781 The prefix can be set via GNU configure to set the install location
2782 (default is /usr/local).
2784 * YAZ programs client and ztest were renamed to yaz-client and
2785 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2786 locations, such as /usr/bin,/usr/local/bin,etc.
2788 * YAZ Header files were moved from include to include/yaz. YAZ Header
2789 files are referred to as include <yaz/log.h> rather than <log.h>.
2790 The YAZ include path (-I ..) is therefore the same as before. Programmers
2791 should update their #include statements or use -Ipath/include/yaz
2792 instead. The main motivation for doing this change is that YAZ header files
2793 can be installed in "standard" locations /usr/include,/usr/local/include
2794 without introducing conflicts, since ALL YAZ header files are stored
2795 in subdirectory yaz (under /usr/include for example).
2797 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2798 rather than project/workspace files. We switched because project files
2799 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2802 Changed name of logging function, logf, to yaz_log, to prevent name
2803 clash with some math-log functions. The YAZ header log.h defines logf
2804 to yaz_log (#define) so there should be no incompatibilities by this
2807 Added bend_start/bend_stop handlers for server. These handler are
2808 called on start/stop of server. For windows they are called whenever
2809 a service is started/stopped.
2811 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2812 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2813 in util/yc.tcl. The auto-generated C code structures are, in a few
2814 cases, incompatible with the old decoders. There are differences in the
2815 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2816 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2817 The preprocessor variable ASN_COMPILED is defined when the compiled
2818 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2819 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2820 wish to use the old encoders/decoders you can specify --disable-yc
2823 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2824 version so that it supports both new - and old version of DB Update
2826 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2827 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2828 change. The name parameter can be set to 0 in which no name is specified
2829 for the construction. The macros odr_implicit and odr_explicit sets name
2830 parameter to zero for the construction involved. New macros
2831 odr_implicit_tag and odr_explicit_tag are similar to the others,
2832 except that a name parameter is added. For programmers' that don't use
2833 ODR they probably only need to change the call to z_APDU and z_External.
2835 Added access control facility by interfacing the TCP wrapper library.
2836 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2837 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2838 name of the daemon and enables the access control as specified in
2839 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2841 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2842 den Dool <H.M.vdnDool@kub.nl>.
2844 Added reference ID parameter to most functions in server API - refer
2845 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2847 Changed name of ccl library to libccl.a (was ccl.a).
2849 Fixed bug in decoder for Explain (Category TargetInfo).
2851 Added support for GNU readline in client. Thanks to Jacob Poulsen
2852 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2854 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2855 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2856 IMPLEMENTATION! This change was made to the development version before
2857 the ZIG decided to retract the amendment. If any users MUST be
2858 compatible with the original Update definition, PLEASE CONTACT US, and
2859 we will include a separate definition corresponding to the old Update
2860 ES. Note that because of the change to the ASN.1 of the
2861 TaskPackageRecordStructure we cannot define a single structure that
2862 will support both versions.
2864 * Added const modifier to buffer parameter for some ODR/BER encoding
2865 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2866 completeWAIS, odr_dumpBER.
2868 Fixed bug in client.c which caused a crash when a scanResponse didn't
2869 contain positionOfTerm.
2871 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2872 * will cause an error in a client if a non-YAZ target sends both a
2873 * list of Scan entries and non-surrogate diagnostics.
2875 Retrieval module enhancements. Tag sets may be typed in the reference
2876 to it. From the .abs-file the "tagset" directive takes a third optional
2877 integer type for the tag set referenced. From a .tag-file the "include"
2878 directive takes a third optional type as well. The old "type" directive
2879 in the tag set itself is still recognized but acts as the default type
2882 Backend interface change. Individual Scan terms returned from bend_scan
2883 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2884 in include/backend.h.
2886 Retrieval module enhancements. Multiple tag sets and attribute sets may
2887 be specified in abstract syntax specs. Revised the error/warning for
2888 logging messages reported by the retrieval module when reading the
2891 Object Identifier system (oid_..) changed. The API is backwards
2892 compatible but the oid-routines now allocates new OID's when needed.
2893 Raw OID's may be specified in oid_getvalbyname.
2895 YAZ now uses GNU configure to generate Makefile(s).
2897 * Minor changes in some of the member names of DeleteResultSetRequest and
2898 DeleteResultSetResponse. See include/proto.h.
2900 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2901 and added member 'languages' in TargetInfo (which was missing).
2903 Changed the way attribute sets are handled in the retrieval
2904 module. These are now cached, just like the abstract syntaxes
2907 Changed YAZ so that it links with compiled ASN.1.
2909 Added Explain-schema definitions and mapping routines. The following
2910 Explain categories have been implemented: AttributeDetails,
2911 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2913 Fixed minor bug in Windows version of Server Library.
2915 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2917 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2919 Added EXTERNAL: UNIverse Resource Report (non-standard).
2921 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2922 ENUMERATED and SET OF.
2924 * Added 'const' to some of the char pointer arguments for the
2925 functions, data1_read_node, data1_getelementbytagname,
2926 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2929 Fixed bug in data1_insert_taggeddata - the last_child member of
2930 parent wasn't initialised.
2932 * Changed data1_read_record and data1_read_node so that the supplied
2933 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2934 doesn't refer to any parts of the "SGML"-buffer.
2936 Fixed bug in server library (Windows version of statserv_remove).
2938 * Changed code so that it compiles as C++. The type definition
2939 of Odr_fun which is a member of Odr_arm was changed. The result is,
2940 that an explicit typecast is needed for the fun pointer when
2941 using Odr_arm - as in:
2942 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2944 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2946 Implemented the new structured date and time definition as approved
2947 by the ZIG. Added schemaId element to the specificTag in Espec-1
2948 (also approved at the last ZIG). Thanks to RVDM.
2950 Added some Object identifiers (RVDM).
2952 Changed the Update Extended Service (RVDM).
2954 Added command "refid" to client which specifies referenceId for
2955 the following requests.
2957 Implemented extended service handling for server. See ztest.c
2958 for an example as well as backend.h. New handlers are registerd
2959 in the Init handler.
2961 * Changed interface for sort in server.
2963 Added new members to statserv_options_block. It allows a server
2964 to read options from another source than just the command line. Thanks
2965 to Charles Woodfield.
2967 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2968 renamed to zboolean. Some C++ compilers complained about the name.
2970 Minor changes to gils.abs. Added index 's' (sort) on title
2971 and date/time-last-modified.
2973 --- 1.4pl2 1998/1/30
2975 Fixed bug in server library regarding inetd mode (-i). This bug
2976 was introduced by release 1.4.
2978 --- 1.4pl1 1998/1/29
2980 Added sort facility in client and backend server interface.
2982 Fixed problem with dependencies in Makefile(s).
2984 Fixed bugs for encoders/decoders of extended services and
2987 Implemented sub-tree feature for schemas. Sub-trees are
2988 referenced in *.abs-files. See explain.abs for an example
2989 of the use of this feature.
2991 Modified bib1.att; local attributes for ANY didn't include
2992 ANY itself (only affects use of the retrieval module).
2994 Fixed bug in plain SGML reader in function data1_read_node:
2995 tags with prefix "var" was incorrectly interpreted as variants.
2997 Added feature "sub-schemas" to enable references to - and definitions
2998 of - group of elements.
3000 * Removed member parent from type data1_element (in data1.h).
3002 Implemented function odr_nullval() that returns the value of
3005 * Removed member num_children from data1_node (in data1.h).
3007 Made NT service interface part of the server library. The
3008 function statserv_main uses the NT service when required and
3009 calls the statserv_start / statserv_close routines.
3011 Routine zget_SearchRequest and zget_PresentRequest fills
3012 resultSetName/Id member with "default" instead of "Default".
3014 Fixed memory leak in server. Request queue member wasn't freed.
3016 Fixed nmem_exit so that memory is freed.
3020 Revised the CCL parser utility to be thread safe.
3022 Added function, oid_ent_to_oid, to replace the function
3023 oid_getoidbyent, which is not thread safe.
3025 * Added nmem_init and nmem_exit to initialize and release
3026 NMEM resources. Function nmem_init should be called once in the
3027 initial thread before NMEM/ODR is used. statserv.c and client.c
3028 have been changed accordingly. The change was necessary to make
3029 NMEM thread safe. The NMEM memory pool is shared amongst threads
3030 in a process. Unix-based applications will still work fine without
3033 Added NT Services interface for the the Z39.50 (statserv) Server.
3034 Refer to the ztest.c source on the usage.
3036 Windows 95/NT port using MSVC5.0. Project files are included in the
3039 * Defined new 'global' handle for the retrieval (data1) system. The
3040 new handled, data1_handle, describes the state of the data1 system.
3041 This handle is passed as first argument to virtually all
3042 data1 related routines. The functions data1_create and data1_destroy
3043 creates and destroys a data1 handle respectively.
3045 Added ODR encode stream member to all backend request structures
3046 init, search, scan etc. This stream should be used to allocate all
3047 memory used for the response when thread safe operation is needed.
3049 Changed the comstack utility, cs_addstr, to be thread safe. The
3050 returned hostname string returned by the function is now part the
3053 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3054 function. The cs_straddr takes a COMSTACK handle as argument, so this
3055 function must be used after cs_create and before bind/connect.
3056 This function is thread safe.
3058 Moved test server to 'ztest' directory - generic server code still
3059 in 'server' directory.
3061 Made prefix query (pquery.c) utility thread safe.
3063 Added new function modifier YAZ_EXPORT to 'export' public DLL
3064 functions when using windows (see include/yconfig.h).
3066 Added definitions to the OID database (util/oid.c) (RVDM).
3068 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3070 Added call to ccl_rpn_delete in client program.
3072 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3073 release of RPN structure.
3075 Added support for C++, headers uses extern "C" for public definitions.
3076 With input from RVDM.
3078 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3079 Thanks to Ronald van der Meer (RVDM).
3081 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3083 Added support for private extensions to the OID database
3084 (oid_setprivateoids()). Thanks to RVDM.
3086 Added optional, physical ANY (key replication)
3088 Fixed null-reference problem in GRS-1 output filter.
3090 Proximity operator added to Prefix Query Format (PQF).
3092 In test client command "base" accepts multiple databases.
3094 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3098 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3100 Smallish bug-fixes in the new encoders/decoders (explain).
3102 Bug fixed in DeleteRequest.
3104 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3106 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3108 Added SOIF syntax (using private OID for now) to retrieval module and client.
3110 Added Update extended service.
3112 Added SearchResult-1 additional info structure.
3114 Added optional CCL (ISO8777) interpreter as separate module. Available
3117 --- 1.2 1996/6/10 (1st anniversary release)
3119 Added Summary record syntax. Lightly tested.
3121 Added OPAC record syntax. Untested.
3123 Added ResourceReport service encoders/decoders. Untested.
3125 Fixed bug in z_Unit - wrong tagging on unitSystem.
3127 Fixed bug in the DiagRecs decoder.
3129 Added options for max PDU size and session timeout to frontend-server.
3131 Added documentation of query-language parsers and other supporting utilities.
3133 [frontend-server] Added Attribute set to the bend_scanrequest API.
3135 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3136 surrogate diagnostics were generated.
3138 [retrieval] Allow multiple local values for attribute.
3140 [retrieval] Allow multiple attributes per element in .abs files. index type.
3142 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3144 --- 1.1pl2 1996/4/10
3146 Minor changes, mostly specific to Zebra's requirements (retrieval)
3150 Repaired bug in frontend server when running multiple listening
3151 endpoints in dynamic mode.
3153 z_External() now won't break if a known, ASN.1 value comes encapsulated
3154 in an octet-string. The value will pass through unmodified in an Odr_oct.
3156 Added a bit of code to the demo client to decode & display
3157 ASN.1-structured records represented in the octet-aligned branch of
3158 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3160 Added z_ext_getentbyref() to the ASN module. Doc updated.
3162 * Completed the SCAN definition in the ASN module. This may break SCAN
3163 code based on older YAZ-versions at compile-time. The fix is easy -
3166 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3167 under the SCAN definition. Remember to initialize this, server-people.
3169 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3170 that this does not extend to ODR and ASN.
3172 Comstack allows insertion of established socket (primarily for
3173 inetd-operation of servers). Doc updated.
3175 Front-end server can now start from the inetd in TCP mode. Doc
3178 --- 1.0pl4 1996/1/24
3182 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3183 the rank and record number.
3185 Adjustments to the frontend server.
3187 Fixed diagnostic BER dumper. It ignored the file argument.
3191 Various changes to retrieval module.
3193 Changed the union discriminators of the protocol files from enums to
3194 ints paired with #defines.
3196 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3199 *Changed operator in the RPN structure to 'roperator', again to avoid a
3202 Fixed problems in Explain decoders/encoders.
3204 --- 1.0pl2 1995/12/6
3206 Memory bug in log module fixed.
3208 --- 1.0pl1 1995/12/5
3210 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3212 Bug in Explain DatabaseInfo module fixed.
3214 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3218 The shift to v1.0 signals that we now consider the *core* functionality
3219 of YAZ reasonably stable (the core being more or less equivalent to
3220 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3221 tested (Explain not at all - though that will happen soonish).
3223 Minor changes to code to support Windows port.
3225 Various minor changes after we're getting to use GRS-1 & co. more.
3227 Added Espec-1 format.
3229 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3230 of the protocol and it cannot be selected when encoding (maps into 'string'
3231 when decoding). Needed to talk to some servers.
3233 Demo client can request simple element set names.
3235 Added Diagnostic Format encoders/decoders.
3237 Added simple Close handling to frontend server (no hooks for resource
3238 reporting yet), and demonstration client.
3240 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3242 --- 1.0b3 1995/08/24
3244 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3245 handled incorrectly when records were requested in the searchResponse. This
3246 will only affect you if you use the frontend-server.
3248 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3249 Test-client will ask for and print GRS1. Ztest will return dummy records
3252 Added Explain encoders/decoders to the service-level API. Untested.
3254 Added Extended Services: Item Order encoders and decoders to the Service-
3255 level API. Untested. We could use a recent copy of the pertinent bits
3256 of the ILL protocol to add those bits.
3258 Added diagnostic format 1 encoders/decoders to the service-level API.
3261 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3262 odr_cons.c, which causes a more correct output.
3264 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3265 was always set to 0 when no records were requested in the searchRequest.
3267 * Added better external-handling. This shouldn't harm old code that
3268 *encodes* externals. It can break code that looks for a
3269 'single-ASN1-type' representation, since those types that are known
3270 are now decoded immediately. Look at the SUTRS sample code in
3271 seshigh.c and client.c. Documentation updated.
3273 Handling of structured records in bend_fetchresponse. Length -1 marks
3274 structured record, type is deduced from format field.
3276 --- 1.0b2 1995/06/27
3277 Fairly quick maintenance release to add SUTRS support.
3279 Fixed handling of SUTRS records in the demonstration client.
3281 * Added format field to the bend_fetchrequest and bend_fetchresponce
3282 structures of the backend API (frontend server). When the record is
3283 returned, the value of the format field is mapped to an OID. The
3284 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3285 of the record. The special value VAL_NONE in the bend_request means
3286 that no specific format was requested by the client. Documentation
3287 updated accordingly. Test server (ztest) will return a fixed dummy
3288 SUTRS record if your client requests SUTRS.
3290 Documentation updated accordingly.
3292 You can now set external libraries and RANLIB support in the top-level
3296 First public release.
