3 MARC: fix non-ASCII characters for leader. This is to ensure we can
6 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
7 in one node with structure word.
11 yaz-json-parse: JSON output may be pretty printed by using option
14 Increase default value of max message for Z39.50 Init for GFS, ZOOM
15 and yaz-client. Old value was 1 MB. New value is 64 MB.
19 yaz-client: don't display bogus records from SRU servers. Some SRU servers
20 return more records than given by *maximumRecords*. Skipping those in
23 record_render: simplify buffer return handling and fix at least one bad
24 memory reference, that broke the test_embed_record sometimes.
26 Allow http://user:pass@host notation for yaz_url_exec.
28 zoomsh: allow shell command to be executed. Via the system(3) call.
30 yaz_poll: Allow num_fds == 0
32 yaz-client: fix bad encoding of "itemorder item". The itemorder
33 item <no> - command forgot to use length of encoded Item Request
34 package. Error present since YAZ 3.
36 yaz-ztest: fix bad usage of session handle. Bug was introduced when
37 result sets were saved (271a9c83).
39 SRU recordPacking: guess record packing in response rather than looking
40 at the recordPacking element which, OF COURSE, changed semantics in SRU
43 Decode SRU 2.0 responses. The official namespace for responses, according
44 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
45 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
46 nature.com's server, however, usee namespace
47 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
48 we are now using a glob-expr to match up the namespace. ZOOM C and
49 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
50 I can not find a single real example showing the "real" namespace in
51 the documentation from OASIS. The namespace for requests is different
52 from responses, but this is not added to YAZ yet, when we don't encode
57 zoom/record_render: add support for Base64 decoding fo MARC records
58 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
59 which will decode base64 + ISO2709 marc-8 encoded material from text node
64 Add missing definitions ZOOM_resultset_get_facet_field_by_index
65 and ZOOM_resultset_facets_names.
67 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
70 Change APDU dump printing to avoid long leading blanks. For levels 16
71 or larger the level is shown and the indentation is truncated but
72 recursed with modula 8. This makes it still reasonable easy to read
73 - even for nested BER dumps.
75 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
76 return 0 (incomplete package) in case where the BER package was
77 considered too nested (return value of -2).
79 dumpber: lines of level 15 are not indented further. Two spaces per
80 indentation; indentation 15 or more is indented to a fixed indentation
81 and augmented with a level=<no> indication.
83 zoomsh: increase max size of command+args
85 GFS: No limit in RPN buf size in CQL to RPN conversion.
89 New function for daemon utility, yaz_daemon_stop .
91 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
95 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
96 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
100 YAZ daemon utility relays SIGUSR1 to child process.
102 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
103 would result in en empty database list - which in turn would result in
104 encoding failure for search.
106 Fix reading beyond string in yaz_sort_spec.
108 --- 4.2.30 2012/04/11
110 Add two new SRU diagnostics:
111 236: Access to specified database denied
112 1015: Init/AC: Maximum number of simultaneous sessions for Userid
114 Document the very useful ZOOM-C option "apdulog".
116 CQL to RPN: term may be passed through verbatim. This is enabled with
117 truncation.cql . The assumption being that the term is already CQL.
119 --- 4.2.29 2012/03/20
121 record_conv: leader spec may be given for marc element.
122 The leader spec is given as attribute leaderspec for element marc.
123 For example to convert a MARC21 record from MARC-8 to UTF-8:
124 <marc inputformat="marc" outputformat="marc"
125 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
127 record_conv: allow user-XSLT params. For example:
128 <xslt stylesheet="MARC21slim2DC.xsl">
129 <param name="myparameter" value="myvalue"/>
130 <param name="otherparameter" value="othervalue"/>
133 record_conv: fix error handling for missing marc charsets.
135 CQL: fix extra terms in wrong order.
137 --- 4.2.28 2012/03/06
139 record_conv: modify new API for conversion types. The conversion types
140 may be passed in new functions yaz_record_conv_configure_t and
141 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
143 Avoid mixed statement/variable declare; fixes compilation with Visual
146 --- 4.2.27 2012/02/28
148 Add non-standard SRU diagnostic: 235: "Database does not exist".
149 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
150 Update SRU to Bib-1 diagnostic maps accordingly.
152 CCL: add two new diagnostics for unsupported masking. The new
153 diagnostics are: "Embedded truncation not supported" and
154 "Single charcacter mask not supported".
156 --- 4.2.26 2012/02/23
158 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
160 --- 4.2.25 2012/01/11
162 Build YAZ for Ubuntu Oneiric.
164 CCL: allow parantheses for proximity operands. For example CCL query
165 (a) % (b) is now allowed.
167 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
168 marked dead, rather then being destroyed. If not, the session memory is
169 being free'd before the search/scan handler is finished. Also destroy
170 'request' memory in request_release rather than in various places,
171 which resulted in leaks from time to time.
173 --- 4.2.24 2011/12/21
175 cql_sortby_to_sortkeys: honor sort prefix.
177 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
178 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
179 The rpn2cql family of functions now always returns quoted CQL terms.
181 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
183 --- 4.2.23 2011/12/15
185 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
186 sequence is treated as one. For example, &&a=b&&&c& is identical to
189 --- 4.2.22 2011/12/05
191 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
192 APDUs for a connection to a WRBUF.
194 --- 4.2.21 2011/11/23
196 Fix cql_sortby_to_sortkeys. Completely broken before.
198 Make CCL's @truncation work again.
200 --- 4.2.20 2011/11/09
202 New ZOOM connection setting: tproxy. It's like proxy, but does not
203 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
204 to set resolved address + port for a connection outside ZOOM itself.
206 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
208 --- 4.2.19 2011/11/07
210 Fix uninitialized variable in Solr spell support (could cause SEGV
211 for SRU response decoding).
213 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
214 back-end's addinfo through into the ZOOM response addinfo.
216 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
217 they are separated by a colon and a space rather than simply
220 --- 4.2.18 2011/10/28
222 Add support for Solr spell-checking/suggestions through ZOOM.
223 If a Solr target has been configured correctly for spelling-checking
224 and suggestions, these will now be returned on the ResultSet option
225 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
227 --- 4.2.17 2011/09/28
229 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
230 with a flag whether to substitute escape sequences or not.
232 --- 4.2.16 2011/09/22
234 Fix nmem_strsplit_escape to substitute escape char properly.
236 New option for zoomsh -e , which makes it abort on first error and
237 return process exit code to indicate success/failure.
239 YAZ options utility supports special option -- which makes all it treat
240 all following arguments as non-options.
242 --- 4.2.15 2011/09/16
244 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
245 searched if absolute filename is given.
247 Fix conv_xslt() error-reporting when stylesheet is not found.
248 (The value of fullpath is meaningless in this situation.)
250 --- 4.2.14 2011/09/07
252 Fix problem in CQL sort node creation: un-initialized memory.
254 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
255 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
256 CQL sortby depending on whether Type-1 or CQL is actually sent to the
259 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
260 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
262 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
263 will make it possible to use both single-character mask (#) and wildcard (?)
264 in CCL . Throw diagnostic for left truncation because that is not supported
267 --- 4.2.13 2011/09/01
269 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
270 cases using escapes (\-sequences) and masking.
272 PQF parse fix: A trailing backslash followed by end-of-string (\0)
273 would result in a read one byte beyond string.
275 rpn2ccl may use Z39.50 masking for terms (t=z).
277 ICU check fix. Don't include library -lCrun on Solaris, unless present.
279 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
280 not --cppflags (which seeems like an error in icu-config).
282 --- 4.2.12 2011/08/27 RPM package only
284 cql2ccl: fix conversion of terms: operator characters were not
287 --- 4.2.11 2011/08/25 RPM package only
289 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
290 CCL parser will map both # and ? to their regular expression
291 quivalents (. and .*).
293 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
294 of reserved CQL characters.
296 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
297 is, so that they are passed through.
299 --- 4.2.10 2011/08/24
301 ZOOM SRU mode: more aggressive re-connect.
303 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
304 made available as a utility function, declared in <yaz/logrpn.h>
306 rpn2cql_structure() supports proximity nodes (except that the Type-1
307 proximity node's "exclusion" binary is ignored, as there is no way to
308 express that in CQL). Fixes bug #4564.
312 Fix SEGV that could occur if set command of zoomsh was given without
313 value (2nd argument).
315 Fix SEGV that could occur if unsupported transport was given for
316 COMSTACK - say https (when SSL was unavailable).
318 Build yaz-url on Windows too.
322 New utility to get web content. Header is url.h. A command line tool
323 yaz-url is part of the distribution and packages.
325 Fixes for SSL COMSTACK (when gnutls is in use).
327 New functions yaz_base64{encode,decode}. Header is base64.h.
331 ZOOM C includes HTTP response buffer as additional info if it fails
332 to decode the SRU response.
334 Make wrbuf_json_puts available.
338 zoom: throw diagnostic for invalid value for option "sru". Before a
339 bad SRU request was sent.
341 Adding new utility wrbuf_vp_puts.
343 Add cclxmlconfig.obj to win/makefile. It was missing completely.
347 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
348 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
349 redirect was used at the same time.
351 MARC line mode decoding: be less picky about length given - first
352 5 digits of header that is.
354 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
356 Changes to decoding of SRU records: a record with recordPacking=xml is
357 modified with a new root element <yaz_record> if the recordData contains
358 multiple children elements. This is to make the record XML parseable
361 RPN to SOLR conversion: encode special characters.
363 Generic Frontend Server: fix uinitialized member, stepSize.
367 Fix a bug in SRU decoding of records.. The database records stored
368 had un-initialized memory, but it would only be seen with yaz_record_render
369 and type_spec="ext" .
371 Fix a bug in ccl_qual_dup introduced in 4.2.3.
375 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
379 Add new utilities to convert from CQL to CCL . These utilities have
380 prefix cql_to_ccl defined in cql.h.
382 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
383 lead to memory heap corruptions when ICU utilities were in use.
387 Make compilation work without Libxml2.
389 yaz-client: remove redundant blanks in display of searchResult-1 term
394 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
395 resulting CQL node (tree) in a new node CQL_NODE_SORT.
397 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
398 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
399 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
400 Note that the CQL sortby spec is only converted when the GFS is already
401 converting from CQL to RPN (cql2rpn element).
403 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
404 specify whether to collapse delimitors or not. The existing nmem_strsplit
405 do collapse (collapse parameter = 1).
407 Windows installer: For NSIS, set InstallDir depending on x86/x64.
409 Rename internal func yaz_use_attribute_create. While non-static, this
410 function is not declared in a public header.
414 Add -lCrun when linking with ICU on Solaris.
416 More quicks character set conversions for OPAC records.
420 fix problem with record_render: records were converted (character set
421 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
425 SRU: add methods for handling DADS SRU-proxy facets.
427 Separate OPAC record character set for ZOOM_record. yaz_record_render
428 allows a character set given as charset=from/opacfrom,to where 'from' is
429 the character set of a bibliographic record, 'opacfrom' is character set
430 of OPAC record and 'to' is the target character set.
434 yaz-client: show may XML format records. Command show followed by 'format'
435 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
438 src/stemmer.c: Avoid using unnamed union. It is not supported by some
441 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
444 Update yaz.spec to operate on both SLES11 / Centos 5.5.
446 RPM: Release includes 'indexdata' name. Use indexdata in release name so
447 this package can be distinguished from other vendors.
449 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
450 as determined by configure
452 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
454 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
455 returns no error and no record, the present request is considered
456 partial (only a subset of the records could be returned by backend), and
457 so it is appropriate to set Present Status to partial-4.
461 Move yaz-config man pages to section 1.
463 More documentation about SOLR.
465 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
466 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
467 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
468 peers on some Linux systems. However, in general that does not work
469 so YAZ can not rely on that to work. Debian changed behavior in this
470 respect from Debian lenny to Debian squeeze (still testing as of Oct
472 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
474 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
478 Fix yaz-config output: echo_source not set correctly by configure.
482 SOLR WebService support for yaz-client and ZOOM.
484 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
486 --- 4.0.12 2010/08/17
488 Z39.50 facet support. Facet specifications are passed for search in
489 other-information with ASN.1 as defined in facet.asn and OID
490 .10.1000.81.5 . Facets are expressed as an Attribute list as known
491 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
492 3 is limit (number of entries to get in response). yaz-ztest returns
493 dummy facets if a client asks for them.
495 --- 4.0.11 2010/07/09
497 CCL fixes: bug 2895 and bug 3539.
499 GR1-display: add comma in display - was removed by mistake in
502 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
504 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
506 --- 4.0.10 2010/06/18
508 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
509 result set from a connection. The result set will be on its own
510 thereafter; no operations on it will perform retrievals from a target.
511 Only cached copies are returned.
513 ZOOM C:fix case for HTTP servers responding with Connection:close.
514 Ensure that if there is a current task it is resumed (like fetching
515 more records in a result set) . Bug #3484.
517 PQF parser: use odr_atoi for Odr_int (not atoi)
519 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
520 values that contain any non-digits are treated as string attributes
521 (previously decoding only checked for leading character ([0-9]). PQF
522 encoding: attribute string values are not surrounded by double-quotes.
526 New utility for managing threads - thread_create.h.
528 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
529 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
530 but YAZ' implementation do.
532 Fixes for yaz_cond-functions on Windows 7.
534 DLL export more symbols.
536 zoomsh: show record do NOT render opac.
538 Remove *.la files from Debian and RPM packages.
542 Debian package libyaz-dev depends on libgnutls-dev again (was
543 removed in YAZ 4.0.6, but due to Libtool it is still needed
544 even though yaz-config do not list libgnutls libs).
546 ZOOM: Use only one WRBUF for returning string results for
547 ZOOM_resultset. Reduces memory usage for ZOOM in general.
549 ZOOM: ZOOM_connection do not use a shared pointer to
550 ZOOM_resultset after ZOOM_resultset is destructed by
551 user. Reverts to YAZ 4.0.4 behavior.
555 record-conv: fix problem with at least one XSL conversion -
556 due to probably incorrect usage of XML XSL documents.
560 Fix yaz-config for static mode and the use of SSL (gnutls).
564 Forward decl timeval struct in mutex.h and gettimeofday.h.
566 yaz-config: fix 'static' mode linking.
570 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
571 are wrappers for pthreads or Windows. For Windows these are put in
572 a separate DLL: yaz_cond4.
574 libyaz.la (whole source) is compiled with thread. If thread support
575 is enabled enabled, all source of YAZ is compiled with treading support.
576 This allows core utilities such as yaz_log to use thread facilities.
577 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
578 thread utilities. This commit moves mutex utilities (mutex.c) from
579 libyaz_server.la to libyaz.la.
581 yaz-json-parse displays leading text until error.
585 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
586 patch from Giannis Kosmas.
588 SRU: no longer URL encode SRU database. The URL for an SRU server is
589 a URL and such is alreeady encoded - at least when given with leading
590 http:// or https://. This reverts behavior to YAZ 3.0.50.
592 Support for new MARC XML notation TurboMARC which like MARCXML is a
593 complete representation of MARC/ISO2709.. This one, however, is more
594 compact and allows for faster processing with XSLT. TurboMARC can be
595 used in the marcdisp.h API, from the yaz-marcdump utility and from
598 yaz-ztest can be configured - via the database - to perform certain
599 delays when it performs operations search, present and single record
600 fetch. This allows testers to make yaz-ztest act as a real or even slow
601 Z39.50 server. Refer to the yaz-ztest man pages for details.
605 wrbuf_destroy allows NULL WRBUF passed to it.
607 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
609 Add ZOOM_connection_close.
611 No fixed size buffers for ZOOM shell - bug #3257.
613 tstodr: make it work on s390 platform.
615 New icu iterator-functions. The new icu_iter-functions makes it possible
616 to use ICU chains from many threads.
618 yaz-client: better syntax check for show command.
622 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
625 New simple local-file XML include facility which allows file glob-patterns.
626 Refer to yaz/xml_include.h.
628 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
631 ZOOM_record_get supports new parameter "format" which makes it format XML
634 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
635 JSONText in ECMA-262) is JSONValue, not JSONObject.
639 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
640 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
642 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
643 POSIX/Unix builds .so with major version 4.
645 Remove old LOG_-defines from log.h. They have been obsolete and
646 undefined by default for the last 5 years.
648 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
650 GFS: Remove socket (int *fd) from search_rr handler. The socket
651 descriptor ptr is a facility that allowed a search handler to supply
652 a socket which would serve as a callback - when search was complete.
653 This facility has now been in use for years.
655 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
656 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
657 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
658 returns 'const char *' rather than 'char *. The returned string is
659 read-only and should not be modified by applications. COMSTACK cs_close is
660 now a void function - it no longer returns int. No applications check for
661 the value and the implementations has always returned 0.
663 ZOOM: use size_t for scan hit counts and str size. Functions
664 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
665 occ (hit count) and len (string length) are now of type size_t pointer
666 rather than int pointer. This is to be able to represent large hit counts
667 and to also just to use the proper type for string length (strlen result).
669 New JSON parser. Refer to include/yaz/json.h .
671 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
672 Used to be int in some cases. Many wrbuf_-functions used to return an int
673 indicating some length.. These return values were never used. And so they
676 ODR: odr_malloc, odr_total now takes size_t for size.
678 clone_z_type: fix leak; occurred for encoding failures.
680 --- 3.0.52 2009/12/03
682 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
683 bug was introduced in 3.0.51.
685 --- 3.0.51 2009/12/02
687 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
689 tcpip comstack: fix leak for getaddrinfo.
691 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
692 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
693 Decoding of SRU "path" database is performed by private function
694 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
695 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
697 yaz-client: honor base command for SRU. Change when database setting
698 is applied for SRU and ensure it is kept when a connection is reset.
699 Change also the way errors are displayed or SRU (decoding of packages).
701 --- 3.0.50 2009/11/02
703 Add support for extra request / response data for SRU codecs and GFS.
704 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
705 for extra data response buffer and length. For the GFS, both request
706 and response data (XML) is carried in extra_args and extra_response_data
707 for the search handler. Patch by Ko van der Sloot.
709 ZOOM: For queries that cannot be converted to the specified rpnCharset,
710 ZOOM now returns a diagnostic on the client-side ('invalid query' /
711 10010). This fixes bug #2113.
713 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
714 cmdfile included a 'quit' command that would result in a memory violation.
716 --- 3.0.49 2009/10/01
718 Make a number of functions defined in xmlquery.c static. These have
719 never been declared in a public header file (yaz/xmlquery.h) and was
720 made public by mistake.
722 Improve speed of character conversions (iconv utilities). This makes
723 conversions from MARC-8 faster.
725 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
726 unless type desired is "raw". This will prevent type "xml" from
727 returning ISO2709 .. Which obviously can not be XML parsed.
729 Fix memory leak in ZOOM that would occur if option apdulog was used
730 on a re-used connection.
732 Frontend server logs HTTP requests.
734 Frontend server now sends Z39.50 close when it times out (sesssion has
735 been idle for too long). Versions 2.0.30 and earlier also sent close.
736 But due to a mistake this was disabled in all versions after that, i.e.
737 the server would just close the socket immediately.
739 yaz-client emits a better message when receiving an unrecognised
740 userInformationField.
742 Skip zero-length subfields when decoding ISO2709. This rare case happens
743 if a record has two FS characters in a sequence. Without this patch
744 there would be a reference beyond char array in using_code_len fragments
747 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
749 --- 3.0.48 2009/08/28
751 The show command offered by the zoomsh command now takes a 3d optional
752 parameter type which is what is passed to ZOOM_record. If the type
753 argument is omitted, "render" is used.
755 RPN to CQL conv may use USE string attributes (bug #2978).
757 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
759 --- 3.0.47 2009/07/08
761 Function yaz_xml2query allows a diagnostic element in the PQF XML
762 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
763 code and additional info respectively.
765 The BER BOOLEAN is now the integral type Odr_bool which still happens
766 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
767 typedef'd to Odr_int. This is still an integral 'int', but it may be
768 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
769 ASN-1 compiler as well as programs has been updated to use the new types.
771 --- 3.0.46 2009/06/08
773 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
774 only the bibliographic record was rendered. For type=opac, an OPAC
775 record is only returned if it is present.
777 iconv: small fix for encoding of advancegreek.
779 yaz-client: avoid double display of SRU/SRW records (bug #2798).
781 yaz-client: option auto_reconnect=on really reconnects.
783 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
785 server: avoid null ptr ref for for yaz_poll errors.
787 build: fix RPM build for RHEL 5.3.
789 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
791 --- 3.0.45 2009/03/31
793 Fixed bug #2709: TCP connect returns Invalid argument.
795 Fixed compilation for mingw.
797 Honor charset for raw records (ZOOM_record_get).
799 Fixed use of errno for threaded mode that was seen on Solaris 10.
801 Fixed argument passing with blanks in value for Windows Service.
803 Disable YAZ' own log rotate by default (no 1 GB limit).
804 The variable l_max_size which specifies the log file limit is set to 0
805 (DISABLED): This is due to the fact that YAZ is most often deployed using
806 logrotate. Also YAZ can not perform log rotate because of unsufficient
807 permissions (setuid).
809 --- 3.0.44 2009/02/17
811 List supported encodings in man page for yaz-iconv.
813 Fixed missing SSL libs for --libs output
815 Re-established OID record syntax application-xml. Nobody should use it
816 but we don't want to change soname because of this symbol being absent.
818 --- 3.0.42 2009/02/02
820 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
822 Added member named_result_sets for init handler struct for the GFS. This
823 allows a server to disable named result sets.
825 Removed OID record syntax application-xml.
827 Added support for rule-based transliterator for ICU wrapper of YAZ.
829 Fixed bug #1902: yaz-icu XML output.
831 Make YAZ checks Emacs friendly.
833 BITSTRING value shows value. Bug #2346.
835 ISO2709 decoding: skip control characters from indicator data.
837 Omit sort key by default in yaz-icu's output.
839 Allow combined single char options (again) for YAZ' options function.
841 Utility yaz-marcdump got option to display YAZ version (-V).
843 Allow YAZ to use ICU 3.4.
845 Added new ICU test case which illustrates removal of diacritics.
847 --- 3.0.41 2008/12/29
849 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
851 --- 3.0.40 2008/12/29
853 For configure, using option --without-xml2 also disables Libxslt/Libexslt
856 Fixed bug #2352: yaz-marcdump crashes for certain record.
858 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
860 Added support for Danmarc2 to UTF-8 conversion.
862 Added support for ISO5426 to UTF-8 conversion.
864 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
865 implementation version.
867 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
869 --- 3.0.38 2008/11/10
871 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
872 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
874 ZOOM C now interprets databaseName option for ZOOM connection as path
877 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
879 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
881 Dummy Libxml2 types no longer defined in headers of YAZ'.
883 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
886 --- 3.0.36 2008/09/26
888 Various ODR chapter fixes.
890 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
892 Added missing source for Windows compilation, mutex.c.
894 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
896 For SRU connections in ZOOM all records up to "count" are now fetched.
898 Fixed crash in generic frontend server (and yaz-ztest) which occurred
899 in Windows due to bad error handling for Libxml2.
901 Added facility for sending arbitrary records (ASN.1 any) using
902 ZOOM C's Extended service update. Patch by Sam Reynolds.
904 New options for ZOOM C's connection, logapdu which makes ZOOM log
907 --- 3.0.34 2008/06/18
909 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
911 --- 3.0.32 2008/06/12
913 Fixed memory violation that could occur when decoding UTF-8. This bug
914 was only present in 3.0.30 of YAZ.
916 --- 3.0.30 2008/06/06
918 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
919 GNU TLS is used by default (if found).
921 yaz-ztest returns OPAC records if a client asks for OPAC.
923 Improved speed of MARC-8 encoding.
925 Added support for lossy and loss-less MARC-8 encoding.
927 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
929 Added new Windows Service wrapper (sc).
931 yaz-client's itemorder command may now send a file.
933 Fixed yaz-marcdump to allow the use of NS prefix for record element.
935 Added new function yaz_log_xml_errors.
937 Allow (but warn) unknown XML attributes in MARCXML parsing.
939 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
941 The UTF-8 to MARC-8 conversion now uses a different set of characters
942 for Greek symbols. Bug #2120.
944 --- 3.0.26 2008/02/21
946 Added yaz_daemon (daemon.h).
948 Fixed bug #2068: pkg-config trouble
950 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
952 --- 3.0.24 2008/01/28
954 Document --with-xml2 option.
956 Added OPAC XML XSD (etc/opacxml.xsd).
958 Allow glob mask for name attribute in retrieval element for the
959 generic frontend server's retrieval facility.
961 Changed yaz_poll_poll to return yaz_poll_except for all returned events
962 except POLLIN/POLLOUT.
964 Fixed error handling in cs_listen. Bug #2037.
966 --- 3.0.22 2008/01/20
968 Fixed version in yaz/yaz-version.h.
970 Fixed bug #2027: Crash when closing connection.
972 Changed configure so that ICU support is only enabled if only ICU
973 and Libxml2 is available (because the ICU chain is XML based).
975 --- 3.0.20 2008/01/15
977 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
978 is built. Only this DLL depends on the ICU runtime.
980 yaz-ziffy is no longer part of YAZ. It is distributed separately by
981 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
983 Changed license of CCL module to 'Revised BSD'. After consultation with
984 remaining members of the original EUROPAGATE consortium, we are re-issuing
985 the CCL module without a separate license. The software was developed by
986 Index Data as part of a research project. The special license was included
987 to help feed usage information back to the project consortium to support
988 project evaluation. At this time, the project consortium has long-since
989 disbanded, and the majority of the original principals have retired. At the
990 same time, we have significantly modified the software during the following
991 years, to the point where very practically no original code remains. To
992 simplify re-use of the software, we have contacted those members of the
993 consortium who could be reached, and agreed to re-issue the module as a
994 proper part of the YAZ package.
996 Tcl scripts uses /usr/bin/tclsh as preferred shell.
998 CQL closer to being version 1.2 compliant. CQL also allows free-form
999 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1002 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1003 bug could make Extended services handling crash in the ZOOM layer. This
1004 bug was only present in YAZ 3.0.18.
1006 --- 3.0.18 2007/12/19
1008 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1011 yaz-marcdump reads and writes collection wrapped records.
1013 Handle OPAC for record conversion module.
1015 Fixes for ICU wrapper.
1017 Allow ICU libs to be controlled with --with-icu .
1019 --- 3.0.16 2007/11/12
1021 Added yaz_poll which is a wrapper for select/poll. When poll is available
1022 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1023 sockets to be in use.
1025 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1026 functionality through an XML based configuration (ICU chain). This system
1027 is useful for search facilities such as Pazpar2 and Zebra that needs to
1028 perform tokenization of indexed material. The ICU code in a separate
1029 library libyaz3_icu.a.
1031 Added HTTP tunnel facility for COMSTACK, bug #1752.
1032 This is a facility that allows a Web proxy, such as squid, to tunnel
1033 Z39.50 traffic. This facility is "transparent" to must applications
1034 using YAZ. It's enabled by using pseudo transport connect: followed by
1035 the proxy address, followed by command, then follwed by he regular
1036 "virtual" addresss. For example,
1037 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1039 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1041 --- 3.0.14 2007/09/21
1043 Fixed bad memory reference in ZOOM_record - cuased by member not being
1044 initialized. This was a problem only in YAZ 3.0.12.
1046 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1047 fields were not removed.
1049 Changed the way C code is generated from codetables.xml. Made a MARC-8
1050 conversion trie for each characterSet section rather than codeTable.
1051 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1052 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1054 --- 3.0.12 2007/09/12
1056 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1057 from ZOOM_record_error).
1059 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1061 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1063 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1065 Better SRW-to-Bib-1 diagnostic mapping.
1067 ZOOM C and yaz-client announces SRU version 1.2 by default.
1069 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1072 Fixed in yaz_sru_decode to allow other version than 1.1.
1074 --- 3.0.10 2007/08/22
1076 Added support for SRU scan for ZOOM.
1078 Added support for the use of the older versions or Extended Service
1079 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1080 set to the version , 1=first, 2=second, 3=third. The third version is
1081 what ZOOM C has used so far. And that, obviously, is the default.
1083 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1084 therefore in Zebra and in SimpleServer-based applications). The new
1085 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1086 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1087 which is passed into the back-end search callback function.
1089 Added support for HTTP Basic authentication in clients: the SRU/W
1090 codec encodes the username/password elements of the PDU structure
1091 appropriately, and these may be set using the "user" and "password"
1092 options in ZOOM-C applications (the same options that are used for
1093 Z39.50 authentication).
1095 --- 3.0.8 2007/06/25
1097 Fixed bug #1208: SSL appears to be broken in ZOOM.
1099 Fixed bug #1206: Libxml2 include path weirdness.
1101 Added oid_name_to_dotstring.
1103 Allow elementSetName to be specified for ZOOM C record update.
1105 Allow waitAction to be specified for ZOOM C based for Extended Services.
1107 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1108 syntax OID. Bug introduced in YAZ 3 series.
1110 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1112 --- 3.0.6 2007/06/06
1114 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1115 directory. yaz-client now reads commands from file given by option -f
1116 if specified; then tries to read .yazclientrc in current directory.
1117 Failing that, it reads .yazclientrc from user's home directory.
1119 Added support for correlationInfo Note and ID for Record Update via
1122 Added yaz-client command querycharset which specifies character set for
1123 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1124 (termListAndStartPoint).
1126 Charset ISO5428:1984 is an alias for ISO5428-1984.
1128 Implemented a way to perform scan in a result set using Z39.50. This
1129 is achieved by attaching the result set name in the characterInfo
1130 (type InternationalString) of OtherInformation in the Scan Request PDU.
1131 The result set is identified in the otherinformation by the new OID:
1132 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1133 This allows for scan in result set and faceted search . Zebra did some
1134 of this in the APT term using attribute type 8 and value being result
1135 set. Using the OtherInformation approach for this is cleaner and easier
1136 to work with in proxies and the like. This facility can be used in
1137 yaz-client using new command setscan which takes a result set as first
1138 argument, start position (APT) as second.
1140 Changed decoding of SRU XML packed records to deal with servers that
1141 have recordData with XML data with multiple root nodes. Also make
1142 comparison for recordPacking case insensitive. Again, one server
1143 returns "XML" where others return "xml".
1145 For SRU responses allow Content-Type application/xml as well as text/xml.
1147 --- 3.0.4 2007/05/21
1149 Fixed bug in character set conversion of BER strings. Bug introduced
1152 --- 3.0.2 2007/05/08
1154 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1156 For OID class, use oid_class consistently.
1158 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1161 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1162 character set for bibliographic information interchange". By Giannis Kosmas.
1164 Added documentation on new OID API.
1166 --- 3.0.0 2007/05/02
1168 Changes to generic frontend server interface: added new member
1169 'query_charset' for bend_initrequest structure. A backend init handler
1170 should set this member to its native character set for query terms.
1171 When defined, the frontend server logic will announce this character set
1172 to a client if the negotiationModel bit is set by the client. All server
1173 implementors are encouraged to specify this. If a backend server does not
1174 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1176 Added CCL utility to remove terms (stop words) from resulting RPN
1177 tree. This is handled by functions with prefix ccl_stop_words_ .
1179 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1180 terms in RPN queries.
1182 Clean-up the CCL API. Moved some internal structures from ccl.h to
1183 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1184 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1185 This is replaced by ccl_parser_find_str which takes a string instead.
1187 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1188 libyaz.la is the core of YAZ except the generic frontend server and
1189 does not depend on POSIX threads anymore. libyaz_server.la is the
1190 generic frontend server facilities and uses POSIX thread functionality
1191 if available. The libyaz.la no longer depends on POSIX threads because
1192 the number of global structures is limited. NMEM no longer re-uses blocks
1193 between threads ; it simply free's memory immediately but allocates in
1194 "large" chunks as usual. We don't expect any performance penalties
1195 because of this. The yaz_log system is still using a global log_level so
1196 caution must be taken when modifying it with yaz_log_init_.. +
1197 yaz_log_mask_str. This, however, should not cause any trouble because
1198 these functions are called during initialization of application code
1199 anyway. `yaz-config --libs server` returns libs for server applications;
1200 `yaz-config --libs` returns libs for non-server applications.
1202 New OID database - with public definitions in oid_db.h. Removed old OID
1203 database including the head oid.h and definitions such as enum oid_value
1204 and struct oident. The new OID database uses the same string names as
1205 before but the 'protocol' is gone. There are now only two representations
1206 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1207 converts from string to OID; functions with prefix yaz_oid_to_string
1208 converts the other way.
1210 Change to emit_term() in CQL-to-PQF query translation: when a term has
1211 the /regexp relation modifier, do not process it for leading and
1212 trailing "^" and "*", which have quite different meanings in regular
1215 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1216 write handlers no longer carries a 'last' parameter. This will make
1217 yaz_iconv flush "less" characters. A flush is performed by call to
1218 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1220 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1221 removed, because function yaz_query_to_wrbuf does the same.
1223 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1224 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1226 Deprecated MARC utility functions removed.
1228 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1231 Branch split: YAZ_2_1_55_branch
1233 --- 2.1.54 2007/03/16
1235 Fix to ZOOM-C so that transparent reconnection is properly handled on
1236 connections that are in asynchronous mode.
1238 Fixed compilation on OpenBSD 4.0.
1240 Large strings in GRS-1 records are now properly displayed in yaz-client.
1242 Added character conversion support for "advancegreek"; based on patch from
1245 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1246 sequence is met. Before the error was not set so it would be unknown.
1248 Adjust yaz-marcdump MARC reader so that it skips until record separator
1251 --- 2.1.52 2007/03/07
1253 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1254 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1255 fd_set structure used as a bitmask for the FDs to be selected on.
1257 Using ACX_PTHREAD macro to check for POSIX threads.
1259 Fixed have-vsnprintf check.
1261 --- 2.1.50 2007/02/23
1263 Fixes for configure on BSD. Bug #900.
1265 Added snprintf/vsnprintf wrappers for systems that don't have
1266 limits (heavens forbid).
1268 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1269 created before all previous tasks were completed and removed from the
1270 task queue, the new task could be removed by a mistake.
1272 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1274 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1276 Fixed bug #832: Problem with MARC/charset in yaz-client.
1278 Fixed bug #668: save command line history for yaz-client.
1280 Fixed bug #830: pkg-config support.
1282 --- 2.1.48 2007/01/23
1284 Extended ZOOM result set options with two options that may be read by
1285 a client: resultSetStatus and presentStatus with values as specified for
1287 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1289 Fixed bug #827: Using SSL fails on Debian etch.
1291 Fixed bug #826: Weird looking chars for set of MARC records.
1293 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1294 that is treated as an ItemOrder with itemRequest being an XML document
1295 external. The value of "doc" is the content.
1297 Extended the GFS search facility. New member of bend_search_rr
1298 'estimated_hit_count' signals that hits is known to be an estmate
1299 (higher or lower than real hit count). New member 'partial_resultset'
1300 signals that the search was partial (hit count is lower or equal than
1301 real hit count). For Z39.50, the information is stored in resultSetStatus
1302 member of SearchResponse APDU. For SRU, the information is signalled
1303 via SRU diagnostic 59: "Result set created with valid partial results
1306 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1308 --- 2.1.46 2007/01/13
1310 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1312 Added ZOOM_connection_peek_event.
1314 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1315 the following new functions:
1316 ZOOM_event_nonblock, ZOOM_connection_process,
1317 ZOOM_connection_get_{socket,mask,timeout},
1318 ZOOM_connection_fire_event_{timeout,socket}.
1319 The existing blocking event handler, ZOOM_event, is a wrapper for the
1320 + blocking ZOOM_event_sys_{poll,select}.
1322 Implemented function ccl_xml_config which parses XML version of CCL
1323 configuration (bug #798).
1325 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1327 Added timings utility (yaz/timing.h)
1329 --- 2.1.44 2007/01/03
1331 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1334 Fixed bug #779: Rotation of apdu.log fails.
1336 Fixed for character set conversions:
1337 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1338 Honor G1 set in MARC-8 decoding.
1340 --- 2.1.42 2006/12/17
1342 Fixed bug #775: char conversion does not handle Alternative UTF-8
1345 Implemented function yaz_marc_read_line which parses MARC line format
1346 records. There is a wealth of formats out there. So far, this function
1347 reads line records produced by yaz_marc_write_line.
1349 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1350 more generic and easier to remember(!) options: -i format and -o format
1351 which specifies input format and output format respectively - where
1352 format is one of "marc", "marcxml", "line", "marcxchange".
1354 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1355 does not print anything except warnings for records.
1357 For yaz-marcdump, added support for MARC split into files (-s) with a given
1360 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1361 spec, at http://www.loc.gov/standards/sru/record-update/
1362 This has changed the binary layout of the following structs:
1363 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1364 bend_update_rr . Patch by Ko van der Sloot.
1366 Added GFS utility function bend_assoc_is_alive which returns 1 if
1367 association is still alive (client is connected); 0 otherwise (client
1368 closed connection). This allows busy servers to stop working for
1371 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1372 been a separate piece of software. This version of ziffy has been modified
1373 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1375 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1377 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1378 Client code may now interrogate options such as "init_opt_sort" to
1379 find out whether the server claims to support various options.
1381 --- 2.1.40 2006/11/27
1383 Added utilities yaz_{set,get}_esn to set/get element set name from
1386 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1387 of YAZ and has been so since YAZ 2.1.10.
1389 Implemented ZOOM_record_error which returns error information for
1390 record (surrogate diagnostic).
1392 --- 2.1.38 2006/10/31
1394 Updates for SRU Update by Ko van der Sloot:
1395 1. Changed name from "operation" to "action"
1396 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1397 versions in the code, marked as 'backward compatible'.
1398 3. Added diagnostics for SRU Update.
1400 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1402 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1404 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1406 For GFS, fixed problem with SRU diagnostic 'First record position out of
1407 range' being issued for 0 hits.
1409 zoomtst10 part of Windows Build.
1411 --- 2.1.36 2006/10/13
1413 Implemented yaz_filepath_comp which splits a path into file path
1414 components (required by Zebra 2.0.3+).
1416 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1417 BSD inspired license until now so this should not have any real impact on
1418 anybody. See http://www.opensource.org/licenses/bsd-license.php
1420 Fixed bug #687: Missing log lines.
1422 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1425 Fixed bug #689: SRU diagnostics to be added.
1427 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1428 whether a connection is idle (no more work do do).
1430 --- 2.1.34 2006/10/04
1432 Change type of optval from long to int for invocation of setsockopt with
1433 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1435 Added support for specifying the max log file size for the Generic
1436 Frontend Server. The size is given with option -r.
1438 --- 2.1.32 2006/09/21
1440 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1442 --- 2.1.30 2006/09/17
1444 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1447 Fixed bug in Generic Frontend Server that could cause a server to stop
1448 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1450 For the generic frontend server, the maximum record size is used as maximum
1451 size of incoming packages (SRU + Z39.50). The value until was previously
1452 only used in Z39.50 Init negotiation and, later, in a session controlled
1453 sizes of records returned. This is controlled using -k option. It can be
1454 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1456 --- 2.1.28 2006/09/04
1458 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1461 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1463 New option for yaz-marcdump -lpos=value which allows setting a portion
1464 of MARC header to a certain value.
1466 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1468 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1469 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1471 --- 2.1.26 2006/08/15
1473 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1476 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1478 --- 2.1.24 2006/08/08
1480 Fixed MARC ISO2709 encoding routines to deal with character set
1483 Minor changes to GFS logging. Database included in search request log
1486 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1487 cached/multiple records.
1489 Shared libraries are built by default on Unix+configure.
1491 Changed cql2pqf transformation to use a different evaluation order. The
1492 new order is: always, relation, structure, position, truncation, index
1493 and relationModifier. Old order was: always, relation, relationModifier,
1494 structure, index, position, truncation. Note that the the latter ones
1495 override former ones for identical attributes.. The new scheme means that
1496 it is possible to override any existing attribute with a relationModifier.
1497 And also that it is possible to override everything for the index rule
1498 (except the ones listed in relationModifier). No order is perfect but this
1499 one, we believe, covers more real cases.. The "always" should have been
1500 called "default", since the attributes there can be overridden with all
1503 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1504 compilation phase, but also for yaz-config --cflags output. This allows
1505 us to have public headers with Libxml2 stuff in them . It should also,
1506 eventually, make Libxml2 checks redundant in packages using YAZ, such
1509 --- 2.1.22 2006/06/15
1511 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1512 stored in uri, message and details.. Previously diagnostics were stored
1513 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1514 compatibility.. but he's probably the only one affected, so.
1516 Added support for CCL, compiled on the client side, in ZOOM-C. This
1517 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1518 input; the resulting query objects can be used for for searching with
1519 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1521 YAZ' configure searches for OpenSSL by default.
1523 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1524 SL_CTX_use_certificate_file. See
1525 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1526 for more info. Thanks to Ko van der Sloot.
1528 --- 2.1.20 2006/06/02
1530 Bug #600: SRU GET, POST support for yaz-client. Introduced
1531 command 'sru' which selects method SOAP/GET/POST.
1533 Allow missingValueAction to be specified for the sortspec string -
1534 function yaz_sort_spec. By default, the missing value action is null.
1535 Use ! to specify "abort". Use = followed by stringvalue to specify default
1538 Ensured that Present-handler (if defined) is called in GFS before any call to
1539 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1540 searchRetrieve requests.
1542 Documentation for YAZ is now based on the Docbook XML/XSLT using
1543 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1544 is no longer depending on jade/openjade or docbook-to-man scripts.
1545 PDF is no longer part of the distribution - but can optionally be
1546 made using DSSSL/jadetex or FOP.
1548 Added retrieval handling support in Generic Frontend Server to support
1549 conversion between MARC/XML as well as XSLTtransforms. See
1550 etc/yazgfs.xml for an example.
1552 Added Authentication support to Generic Frontend Server in SRU
1553 mode. Authentication using HTTP Basic is supported, as is the use
1554 of 'x-username' and 'x-password' parameters in the request itself.
1556 Added support for a new character set MARC8s identical to MARC8 except
1557 that it converts combined characters to single Unicode characters in the
1558 Latin-1 range (when possible).
1560 --- 2.1.18 2006/04/24
1562 ASN.1 compiler 0.4: generates brief Doxygen file header for
1563 generated .h/.c files.
1565 Utility yaz_iconv now supports conversion to MARC-8.
1567 New facilities for the MARC module. The reading - and writing of
1568 content are separate methods for the yaz_marc_t handle. The following
1569 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1570 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1571 format). Write functions have prefix yaz_marc_write_.. The existing
1572 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1573 available. Removed support for OAI-MARC and simplexml (not the
1574 simplexml from PHP5).
1576 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1577 to be returned for this connection.
1579 --- 2.1.16 2006/03/31
1581 Allow multiple languages and charsets to be specified with
1582 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1583 negcharset iso-8859-1,utf-8
1585 Translation of proximity nodes from CQL into PQF now works.
1587 Moved to automake 1.8, 1.9.
1589 Added function yaz_log_set_handler which allows a log handler to be
1590 installed. This handler will be called for all log messages. Output
1591 to file is also produced; but that can be disabled by passing NULL
1592 fname to yaz_log_init_file.
1594 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1596 For SRW (including GFS), accept application/soap+xml as content-type
1599 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1600 produces NO stylesheet reference even if a default stylesheet is specified
1603 --- 2.1.14 2006/03/14
1605 Updated Windows package to include yazd.dll + yazd.lib for the
1606 Development component.
1608 If the environment variable YAZ_LOG is set, then it is used as a
1609 string indicating the default level of logging to use if not
1610 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1611 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1612 used as before. So, for example, to omit warnings from YAZ logging,
1613 export YAZ_LOG=-warn
1615 cql_transform() now map structure and other attributes before indexes,
1616 so that index-specific structures and other attributes can override
1617 defaults. So now a combination of mapping specifications such as:
1619 index.dc.date = 1=date-modified 4=5
1620 does the right thing.
1622 cql_transform() now also respects the "always" mapping specification,
1623 which establishes an initial set of attributes to be used for all
1624 terms except where overridden by more specific attributes associated
1625 with the index, relation or modifier.
1627 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1628 which mode to use; one of "post", "get" or "soap" (SRW, default).
1630 Fixes for yaz_iconv routines: changed trie-based character set conversions
1631 to use only non-negative values for bit fields due to Sun's C compiler not
1632 supporting negative values.
1634 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1635 sequences where not read correctly. Fix by Rustam Usmanov.
1637 Updated win/makefile to use options, settings which makes things
1638 compile with VS C 2005.
1640 --- 2.1.12 2006/02/01
1642 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1644 In ZOOM socket code, use select instead of poll on MacOSX.
1646 ZOOM-C now support client-side compilation of CQL into RPN that is
1647 sent to the server, enabling CQL to be used against all Z39.50
1648 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1649 ZOOM_query object, and submit it using ZOOM_connection_search().
1650 The CQL-to-RPN translation uses a configuration file, the name of
1651 which must be specified in the Connection's "cqlfile" option.
1653 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1654 function, which takes as its start-term parameter a ZOOM_query object
1655 (which may have had either CQL or RPN set into it).
1658 --- 2.1.10 2005/11/29
1660 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1661 GFS to support this as well. Backend handler, bend_srw_update, does the
1662 update work. Code contributed by Ko van der Sloot.
1664 Allow retrieval of Search Result-1 information in ZOOM by the use of
1665 options that are attached to a result set. ZOOM documentation updated
1668 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1669 UTF-8 conversion. Patch by Raj Patel.
1671 Added option -m to GFS to control formatting of timestamps in log file.
1673 Added 'exit' as synonym for 'quit' in yaz-client
1675 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1676 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1677 for the new members. Patch by Ko van der Sloot.
1679 Added support for SRU POST. It is supported for content-type
1680 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1682 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1683 Instead make the library libyaz.la multi-threaded. Threading as a whole
1684 can still be disabled by configure option --disable-threads. Previosly,
1685 with older GLIBCs there were problems with MT libs under Apache. This
1686 has now been fixed a long time ago.
1688 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1691 CQL module modified to be case insensitive for relations/indexes/operations.
1693 Fixed bug in CQL transform code: incorrect value relationModifieder
1696 Added 'show all' command for yaz-client which retrieves all results
1699 Added new yaz-client, xmles, which takes a (private) OID and
1700 a document to be sent as an extended service request.
1702 Describe new yaz-client commands wait_response and set_auto_wait.
1704 Increase TCP/IP listener backlog from 3 (which I am guessing was
1705 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1706 that the socket will queue as many incoming connections as it's able
1707 to handle ongoing connections. In other words, it will never now
1708 refuse a connection that it would be able to handle merely because
1709 it's not got around to accepting() enough of the pending connections
1710 yet. This is the behaviour anyway under Linux, where the listen()
1711 argument is ignored; but not under BSD and on systems such as
1712 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1713 YAZ-based servers should now be uniform across operating systems in
1716 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1717 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1718 This allows yaz-marcdump to read large MARC batches (>2 GB).
1720 Modified all YAZ source files - except the source which is auto-generated
1721 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1724 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1725 corresponding to the existing *_setl() function. These allow option
1726 values containing arbitrary valuues.
1728 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1729 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1730 except that it returns an indicator of whether or not the sort
1731 criterion was accepted (0 for OK, -1 for invalid).
1733 --- 2.1.8 2005/06/07
1735 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1736 MARC output rather than returning "new" buffer.
1738 yaz-client warns about unknown init options.
1740 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1742 --- 2.1.6 2005/05/24
1744 Added support for SRW sort in Generic Frontend Server. Patch
1745 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1746 sortKeys - or NULL if none is provided.
1748 Fixed bug #307: It was impossible to specify indefinite/no timeout
1749 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1752 Added support for multiple languages and charsets to be specified in
1753 ZOOM. Each charset/language is separated by a blank. If negotiation is
1754 in effect in init-response, Option
1755 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1756 Code based on patch by Vasiliy Osadchuk.
1758 Fixed bug #306: infinite recursion that occurred when calling
1759 yaz_log_level_init as the first call (before other log level or
1762 Fixed bug in scan handling in front end server: if preferred-Position-In-
1763 Response was non-present, a NULL pointer referece was performed.
1765 --- 2.1.4 2005/04/26
1767 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1768 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1769 now defined for all those error codes. So instead of putting 109 in
1770 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1771 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1773 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1776 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1778 Program yaz-client now exits and produces an error message if multiple
1779 Z39.50 servers are specified on the command line (none or one allowed
1782 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1785 --- 2.1.2 2005/03/16
1787 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1789 Fixed bug #272: Preserve spacing for CCL terms.
1791 --- 2.1.0 2005/03/14
1793 Added support for virtual hosts and multiple backend servers for
1794 the YAZ frontend server. The configution is XML based and
1795 support specificition of CQL to RPN mappings and explain information.
1796 See section "Virtual Hosts" in the YAZ manual.
1798 Extended OPAC display utility. OPAC display utility renders
1799 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1800 to supplement yaz_marc_decode_wrbuf.
1802 Fixed a bug in MARC decoder that could caused it to crash for some
1803 invalid MARC records. More diagnostics and warnings where added in
1804 XML output (warnings, etc are stored in comments).
1806 --- 2.0.34 2005/02/08
1808 Fixes for UNIX domain sockets. Bug #261.
1810 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1812 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1813 Added yaz_marc_subfield_str which defines subfield lead string which is
1814 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1815 yaz_marc_endline_str which defines end of fields string used in
1816 YAZ_MARC_LINE format. Default string is newline.
1818 Experimental support for MarcXChange. This format can be produced
1819 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1820 http://www.bs.dk/standards/MarcXchange.xsd
1822 Added yaz-client commands scansize that sets maximum number of
1823 entries to be returned by scan.
1825 --- 2.0.32 2005/01/11
1827 Added support for SRW scan in yaz-client and Generic Frontend Server.
1829 * Added whereInList member to SRW Scan Term.
1831 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1833 Fixed NMEM system to return aligned blocks on the smallest boundaries
1834 that are suitably aligned for all possible types on the particular
1835 architecture YAZ is being built for.
1837 --- 2.0.30 2005/01/04
1839 Fixed numerious warnings that was issued with newer versions of GCC.
1841 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1842 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1845 Make YAZ Generic Frontend Server slightly faster.
1847 Enhance (and reduce) logging for Generic Frontend Server.
1849 Revert YAZ log system so that it flushes every write operation
1850 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1852 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1853 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1854 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1855 will effectively disable old definitions.
1857 --- 2.0.28 2004/11/09
1859 Added yaz_log_time_format which specifies log format using
1862 Added yaz_log_module_level which returns mask for a module. Value
1863 is non-zero mask a if module is enabled; zero if disabled.
1865 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1866 in include/yaz/cql.h.
1868 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1870 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1872 Fixed bug #172: RPM builds does not enable SSL.
1874 Doxyfile.in part of dist. Doxyfile generated by configure.
1876 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1877 are given and the corresponding component does not exist.
1879 Extend CCL documentation in YAZ reference. Describe r=r.
1881 --- 2.0.26 2004/10/01
1883 Fixed MARC->MARCXML conversion to properly deal with
1884 fields, subfields, indicators having non-ASCII characters.
1886 Fixed MARC->MARCXML conversion so that ASCII control characters
1887 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1890 Added YAZ GFS support for conversion from Z39.50 surrogate
1891 diagnostics to SRW surrogate diagnostics.
1893 Bug fix: YAZ GFS did not return schema in explainResponse.
1895 --- 2.0.25 2004/09/30
1897 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1898 now converts recordSchema to elementSetName as well as schema URI.
1900 Fixed bug in COMSTACK that prevented HTTP request packages from being
1903 --- 2.0.24 2004/09/29
1905 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1906 does not require white-space before and after the dash in a range, e.g.
1907 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1910 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1911 due to new GCC removing "redundant" code.
1913 Added yaz-client commands scanpos and scanstep that sets preferred
1914 position and step-size for scan.
1916 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1918 Added CCL utility ccl_qual_buf which parses one or more CCL
1919 spec lines in a buffer.
1921 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1922 of name and value - ignoring empty lines and comments.
1924 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1926 Added odr_get_element_path which returns current element path for an
1927 ODR handle. This utility is useful in error handling or user-defined
1930 Added ODR_PRINT utility odr_set_stream which is is a more generic
1931 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1932 to a write function and pointer to close function. The close function - if
1933 non-NULL - will be called during odr_destroy.
1935 Fixed bug in CCL parser where truncation char was not removed from
1936 right side when truncation=both was in effect.
1938 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1941 --- 2.0.23 2004/08/11
1943 Fix buffer overrun in CQL parser when dealing with proximity (%).
1945 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1946 to UTF-8/UCS conversion is now only based on codetables.xml.
1948 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1950 --- 2.0.22 2004/08/06
1952 Add support for more "commit changes" in ZOOM (uses Extended Services).
1954 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1957 Yet another small fix for configure of SSL.
1959 --- 2.0.21 2004/05/14
1961 Fix SSL libs for configure when --with-openssl=DIR is given.
1963 --- 2.0.20 2004/05/10
1965 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1967 SSL comstack now uses yaz.pem certificate file on server side
1968 by default. Certificate filename can be configured by calling
1969 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1971 Fix bug regarding multiple calls to ZOOM_connection_connect.
1973 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1975 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1976 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1978 ZOOM now allows inspection of X509 peer certificate for verification.
1979 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1981 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1982 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1983 as "modular" but it simplifies things.
1985 Added cs_get_peer_certificate to that returns peer X509 PEM.
1987 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1988 NULL if SSL is unavailable.
1990 Documentation about MARC decoding tools.
1992 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1994 --- 2.0.19 2004/03/30
1996 Rename CHANGELOG to NEWS to follow GNU style packing.
1998 Fix bug with missing initialization of member in init_diagnostics.
1999 This bug affects threaded version of GFS server.
2001 --- 2.0.18 2004/03/20
2003 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2006 Ensure zlib.dll is packed with Windows install.
2008 --- 2.0.17 2004/03/17
2010 Fix encoding of xsd:string to use text instead of CDATA.
2012 Fix endless loop in CQL parser with unbalanced ".
2014 Use a more compact way to store MARC-8 conversion tables.
2016 --- 2.0.16 2004/03/16 Debian only
2018 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2021 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2026 --- 2.0.15 2004/03/01
2028 Another fix for decoding of XML packed records.
2030 --- 2.0.14 2004/02/25
2032 Fixes for Chunked encoding. White space not ignored after length spec.
2034 Update NS and use default NS for SRW diagnostic elements.
2036 --- 2.0.13 2004/02/23
2038 Implement ZOOM_resultset_cache_reset which resets record cache.
2040 Implement ZOOM_resultset_sort which sorts a result set.
2042 Implement chunked HTTP transfer.
2044 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2046 --- 2.0.12 2004/02/16
2048 Added member 'schema' to bend_explain_rr structure so that backend
2049 can specify explain record identifier. Defaults to Zeerex 2.0.
2051 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2053 --- 2.0.11 2004/02/16
2055 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2058 Added init command for yaz-client which sends "extra" init request.
2060 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2061 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2063 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2065 Make ZOOM error code for "invalid query".
2067 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2069 --- 2.0.10 2004/02/05
2071 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2074 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2076 Added option -p <file> to make Generic Frontend Server to write PID file.
2078 Added option -D to put Generic Frontend Server in background on its own.
2080 Make ZOOM C recognize option "password". If unset, "pass" is used
2081 (for backwards compatibility).
2083 Fixed a bug in Generic Frontend Server that could make it crash if a
2084 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2087 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2088 Must be issued before open, in order to be in effect.
2090 --- 2.0.9-6 2004/01/12 Debian/Windows
2092 Make the SRU server more picky WRT unknown params, etc.
2094 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2096 New YAZ client command, options, that sets Z39.50 options.
2098 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2099 options from a string of tokens (one token for each option bit).
2101 Update SRW diagnostic code messages.
2103 --- 2.0.9-5 2004/01/07 Debian/Windows
2105 Handle user defined stylesheet for SRW/SRU.
2107 --- 2.0.9-4 2004/01/06 Debian/Windows
2109 Fix bug in decoding of Content-Length.
2111 --- 2.0.9-3 2004/01/06 Debian/Windows
2113 Fix a bug with decoding of XML packed records.
2115 --- 2.0.9-2 2004/01/05 Debian only
2117 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2119 Fix bug in SRW/SRU diagnostics decoding.
2121 --- 2.0.9 2004/01/05
2123 Fixed bug in Generic Frontend Server which could drop records exceeding
2124 preferred message size. Reported and fixed by Irina Dijour.
2126 Fixed calculation of package size for structured records in Generic
2127 Frontend Server. Reported and fixed by Irina Dijour.
2129 Fixed namespace for SRW/SRU diagnostics.
2131 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2133 --- 2.0.8 2003/12/22
2135 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2136 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2139 CQL changes to reflect recent changes to the specification:
2140 * Documentation talks about context sets instead of index sets.
2141 * Documentation talks about indexes instead of qualifiers.
2142 * The CQL-to-PQF transformer's configuration file now uses
2143 "index.set.name = <attributes>" instead of the old form
2144 "qualifier.set.name = <attributes>". (Both forms are still
2145 understood but the latter is deprecated.)
2146 * CQL terms with no explicit index specified are now interpreted as
2147 cql.serverChoice instead of srw.serverChoice (which of course
2148 behaves exactly the same.)
2150 --- 2.0.7 2003/12/16
2152 MARC conversion can now generate ISO2709 output in another
2153 character set. yaz-marcdump uses this facility if you invoke it
2156 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2157 functions from there can be used from C++.
2159 --- 2.0.6 2003/12/04
2161 Frontend server now transfers memory from decoded packages to stream
2164 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2165 references to show up.
2167 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2168 the ZOOM Abstract API. The older names for the same options are still
2169 also supported for the benefit of old applications.
2171 ZOOM-C supports "implementationId" and "implementationVersion" options
2172 to go along with "implementationName". These allow the user code to
2173 specify identification strings to be sent to servers.
2174 Add OID for the new ExtLite attribute set.
2176 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2177 as requested/supplid by Ere Maijala <ere@atp.fi>
2179 For generic frontend server, reverse the order of
2180 "toolkit-supplied / application-supplied" strings sent as implementationId,
2181 Name and Version. Also, remove the spaces around the slash. This brings
2182 the GFS in line with the behaviour of ZOOM-C on the client side.
2184 Add function ZOOM_scanset_display_term.
2186 yaz-client shows scan displayTerm if present.
2188 Utility yaz-iconv is now installed by default along with the man page
2191 Extend configure check for OpenSSL to use pkg-config where available (such
2194 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2195 server to specify uid/gid/mask for socket using the format
2196 unix:[user=uid,][group=gid,][umask=mask,]file=path
2197 If file= is omitted the existing format is assumed, e.g.
2199 in which case the mask is 0666 (rw for everybody).
2201 Major restructure of YAZ source. All source in libyaz is in src directory.
2202 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2203 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2205 Added man page for utility yaz-marcdump (used to be called marcdump).
2206 yaz-marcdump is installed by 'make install'.
2208 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2209 of incoming package failed.
2211 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2213 Change prototype of odr_perror: add const to message string.
2215 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2217 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2218 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2219 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2220 DNS lookup. There should not be any compatibility problems with this
2221 assuming that blocking=1 or 0 is used.
2223 Fix bad reference in UNIX comstack in function cs_addrstr.
2225 Fix for compilation on AIX.
2227 The generic front-end server (server/seshigh.c) now supports returning
2228 Init diagnostics to the client in User-information-field, in
2229 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2232 --- 2.0.4 2003/09/04
2234 Allow any CQL relation (not just all,any,exact,scr).
2236 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2237 that features the same UI.
2239 Implemented command update0 in YAZ client which is equivalent to
2240 update but uses old of Ext Update ASN.1.
2242 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2243 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2244 Previously no OID was used for this info.
2246 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2247 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2248 returns 'malformed search term' otherwise.
2250 SortResponse member resultCount now set to NULL in sort handler of
2253 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2256 Add three new utility functions for translating OIDs between various
2257 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2258 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2259 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2260 char *oid_to_dotstring(const int *oid, char *oidbuf);
2261 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2263 Reverted modifications for ES Update definition for z_IU0Update
2264 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2265 is back to YAZ 2.0.2.
2267 String value attributes for CCL parser.
2269 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2270 which their FirstSearch server returns in Init responses, sometimes
2271 carrying useful diagnostic information when Init fails. This has the
2272 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2273 "z39.50/oclcui.asn", where its definition is somewhat different from
2274 what OCLC document on their web-site, as required to interoperate with
2277 Support for anonymous authentication in yaz-client. Use the command
2280 * Fix the OID of the Index Data-local "admin" Extended Service from
2281 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2282 the 1000, which indicates a locally-defined OID, was a mistake.
2284 --- 2.0.3 2003/06/20
2286 Fix CCL directive @case handling so that it affects string match for
2287 both CCL keywords and qualifiers.
2289 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2290 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2291 Decoder has been updated with ASN.1 changes as listed in
2292 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2293 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2294 z_IUUpdate, remains unchanged.
2296 ZOOM_record_get may now return a record in a specific character set.
2297 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2298 "from" is the character set of record as returned by target. "to" is
2299 the character set to be returned. If omitted, "to" is UTF-8.
2301 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2303 New ODR utility, odr_getelement, which returns name of element for
2304 which encoding/decoding failed.
2306 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2307 in cases where a required element was omitted.
2309 Bug fix: some MARC8 sequences were not converted.
2311 New ZOOM option "step" which specifies number of records to be
2312 retrieved in one chunk. Used in conjunction with "start" and "count".
2314 SRW support for yaz-client. Use scheme http: to use it, e.g.
2317 yaz-client no longer does (un)intelligent character set conversions
2318 by default. Can be enabled with charset and marc_charset commands.
2320 xmalloc trace fix for 64-bit systems such as DEC alpha.
2322 Solaris 2.6 compile fix.
2324 New function, cql_strerror() translates SRW error codes, as returned
2325 by cql_transform_error(), into human-readable English strings. Used
2326 in yaz-client diagnostics when appropriate.
2328 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2329 converts it into a type-1 query which is sent to the server. This
2330 makes CQL available for use with all Z-servers, as opposed to the tiny
2331 minority that can handle CQL queries themselves.
2333 --- 2.0.2 2003/04/28
2335 New Debian package layout similar to the Redhat Package layout.
2337 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2338 and search result respectively.
2340 --- 2.0.1 2003/04/25
2342 Redhat package is now several packages: libyaz (runtime libraries),
2343 libyaz-devel (development and documentation, and yaz (utility programs).
2344 Package spec file by Morten Bogeskov.
2346 New member 'schema' in struct bend_fetch_rr which the name of requested
2347 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2348 handler MAY set this to reflect the schema of the returned record.
2350 New member 'display_term' in struct scan_entry. GFS now sets member entries
2351 and allocates scan entries to be filled by user scan handler. In previous
2352 version, entries member was allocated by the scan handler. That still works,
2353 but the GFS will ignore member display_term - assuming it was NOT set by
2354 the handler. The fact that the GFS now allocates the entries both allows
2355 for new members and makes a scan handler easier to write.
2357 Fix CQL lex buffer overflow.
2359 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2360 SRU default recordPacking is string.
2362 SRU protocol support for frontend server.
2364 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2366 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2368 Added scan for the ZOOM shell (zoomsh).
2372 * String Identifers for Schemas (Amendment 5).
2373 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2374 Old definition for schema
2375 Odr_oid *schema; /* OPT */
2380 Z_InternationalString *uri;
2381 #define Z_Schema_oid 1
2382 #define Z_Schema_uri 2
2385 * resultCount parameter to Sort Response (Amendment 1).
2386 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2388 Support for SRW 1.0 over HTTP. This is an optional feature and
2389 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2392 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2393 on the same port. SRW SearchRetrieveRequests are mapped
2394 to bend_init,bend_search,bend_fetch,bend_close.
2396 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2398 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2399 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2401 ZOOM connections are SRW based if schem http is used for hostname
2402 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2403 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2405 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2406 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2407 distance=n, order=true/false, relation=le, prox unit=word. If
2408 n is omitted, distance 1 is used.
2410 Fixed problem with C compiler include path in wrong order.
2412 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2413 on Solaris. Patch from Ko van der Sloot.
2415 New MARC decode API. All new functions operate on a yaz_marc_t
2416 handle. The most important new functions are: yaz_marc_create,
2417 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2418 decode and destroy respectively. Decoder can produce formats
2419 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2420 include/yaz/marcdisp.h.
2422 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2423 to UTF-8, UCS-32, wchar_t or Latin-1.
2425 * Prototypes for yaz_iconv_-functions moved to separate header
2426 include/yaz/yaz-iconv.h.
2428 Make a few private functions 'static' in unix.c. This prevents
2429 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2431 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2432 are set when Init Response is received.
2434 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2435 but returns diagnostic set as well.
2437 New function yaz_strerror which is a portable wrapper for
2438 strerror/strerror_r/GetLastMessage.
2440 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2441 is returned for MARC. If type is "oai", then OAI MARC is returned.
2443 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2446 --- 1.9.2 2002/11/26
2448 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2450 Fix bad race conditions on SIGTERM and terminate gracefully in
2453 Move retrieval (data1) module to Zebra since nobody seems to be
2456 Add GRS-1 render for ZOOM using same format as yaz-client.
2458 --- 1.9.1 2002/10/05
2460 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2462 Fix broken ESpec handling in data1 module.
2464 SGML reader parses comments and makes them part of the data1 tree.
2466 Added several type casts so that YAZ compiles as C++ code.
2468 ZOOM didn't handle PDU encoding failures properly.
2470 Added more Bib-1 diagnostics (approved extensions).
2472 GNU configure: better check for iconv.
2474 More portable use of accept, getpeername. Check for socklen_t. Use
2475 int/size_t if socklen_t is not defined.
2479 PQF parser rejects bad queries - including those with extra
2480 characters in them. PQF parser used to silently ignore that.
2481 Cleaner API for PQF added, which allows you to get detailed
2482 error information for bad queries (see yaz/pquery.h).
2484 Fixed bug in ZOOM_record_get for type "database".
2486 Implemented mini iconv library supporting conversions between
2487 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2489 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2491 --- 1.8.9 2002/08/20
2493 Fixed ZOOM C record cache so that preferredRecordSyntax and
2494 elementSetName is used to check for already fetched records.
2496 --- 1.8.8 2002/08/02
2498 Added three members in bend_initrequest structure to facilitate
2499 character set negotiation.
2501 Fixed a bug in frontend server that could cause indefinite
2502 loops under rare conditions.
2504 Revised character set utilities (charneg.h) so that encoding
2505 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2507 For PQF, directive @term <type> sets term type for Scan/Search.
2508 Here <type> is general, string, numeric, null. The term type
2509 is inherited - just like @attr.
2511 New call odr_set_charset that sets character set conversion for
2512 international-strings on a ODR stream. Prototype is:
2513 int odr_set_charset(ODR o, const char *to, const char *from);
2514 The InternationalString is still represented as C string in YAZ
2515 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2516 won't). On the protocol level, you can use any encoding.
2518 Support for UNIX sockets in ZOOM.
2520 Solaris recv sometimes returns errno == ENOENT. It is treated as
2521 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2523 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2524 both client and server. Code by Morten Bogeskov.
2526 --- 1.8.7 2002/05/22
2528 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2529 that they can be used directly from Visual Basic. You must recompile
2530 your windows APP if you're using ZOOM.
2532 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2533 Commands "lang" and "charset" sets language and character set respectively.
2534 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2535 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2537 Attributes from multiple CCL fields may be OR'ed rather than merged
2538 using directive "@field or". Fields are still merged by default -
2539 equivalent to "@field merge".
2541 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2544 Fixed bug in zget for parameter ExtendedServicesResponse.
2548 --- 1.8.6 2002/03/25
2550 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2552 Client displays USR.1:SearchResult-1 (hits per term).
2554 Additional Search Info for search in Generic Frontend Server.
2556 Fixed CCL parsing of "field=s".
2558 WIN32 installer - using the excellent NSIS software from nullsoft.
2560 Fixed CCL parsing of "field = - <number>".
2562 Added function yaz_marc_decode that decodes MARC for line mode
2563 display or XML (similar to that used by JZKit).
2565 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2566 Z39.50. But ISO/ILL was, however.
2568 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2569 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2571 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2572 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2574 --- 1.8.5 2002/02/03
2576 New YAZ client features: Command completion and new commands:
2577 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2578 Code provided by Jacob Poulsen.
2580 New call oid_trav, that visits all registered OIDs via callback.
2582 Function ZOOM_record_get now returns const char pointer rather than
2583 void pointer. It saves a lot of type casts.
2585 For YAZ client, command "auth" now allows you to set authentication
2586 in IdPass style. It is enabled when three tokens are given - order
2587 is user, group and password.
2589 Fix memory leaks in MARC record handling for ZOOM.
2591 New option for YAZ client, -k <kilobytes> that sets
2592 maximum record size. Similar to -k option for generic frontend
2593 server and yaz-ztest.
2595 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2597 Prefix query parser reports "fail" when bad attribute set is given.
2599 Fix in MARC decoder. Proximity logging. Fix for attribute set
2600 in scan handler for server. Patches by Shigeru Ishida.
2602 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2605 Configure option --with-openssl=<dir> now works when a directory is
2606 specified. Patch provided by Morten Bogeskov.
2608 New option for YAZ client, -u <auth>, that sets authentication.
2610 ZOOM fix: error information was sometimes "missing", since error
2611 was cleared/reset too when it shouldn't.
2613 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2615 --- 1.8.4 2002/01/04
2617 Scan for ZOOM API. New object ZOOM_scanset. New functions
2618 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2619 ZOOM_scanset_destroy.
2621 New ZOOM function, ZOOM_connection_last_event, that returns type
2622 of last event (such as "receive data", "send data", "apdu received",
2625 New ZOOM option, schema, that specifies schema for retrieval.
2627 New CCL feature. Qualifiers can be aliases for one or more
2628 other qualifiers (if more than one is given, OR is used).
2630 ZOOM uses named result sets if target supports it.
2632 Two new YAZ client commands: . (dot, which sources a script of YAZ
2633 client commands), and ! (to execute shell command.). Implemented
2636 Working on Debian packages.
2638 --- 1.8.3 2001/11/19
2640 YAZ client enables named result sets only if target supports it.
2642 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2644 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2645 with key="host" to get same result.
2647 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2648 Function Z3950_resultset_record(s) returns references to records
2649 "owned" by resultset. To become owner use Z3950_record_clone.
2651 Function z_ext_record handles Extended Services. Thanks to
2654 --- 1.8.2 2001/11/12
2656 CCL Parser fix: ignore token comma when dealing with and-lists.
2658 Documentation updates for COMSTACK.
2660 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2661 Changed prototype Z3950_records. For some functions, int parameters
2662 were changed to size_t.
2664 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2667 New MARC decode/display function, marc_display_exl, which properly rejects
2668 non-ISO2709 records. YAZ client uses it.
2670 --- 1.8.1 2001/10/29
2672 Fix bug: local attribute set wasn't set correctly in PQF strings.
2676 * Old Z39.50 codecs no longer supported.
2678 Added ZOOM C binding. See http://zoom.z3950.org/
2680 Renamed states for COMSTACKs to avoid confusion with events.
2682 Implemented cs_look and proper cs_rcvconnect.
2684 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2686 Configure detects POSIX threads on OpenBSD.
2688 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2689 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2691 When error is returned from present handler, non-surrogate diagnostic
2692 is returned in present response (and fetch handler is no longer called).
2694 * Minor adjustments to pquery parser (PQF). Token characters may be
2695 escaped by using backslash (C-style).
2697 PQF parser allows string attribute values to be specified. For @attr,
2698 non-numeric characters after the equal-sign are treated as strings
2699 (e.g. @attr 9=title).
2701 CCL trunction character may be defined (@truncation in file)
2703 * function zget_ExtendedServicesRequest sets waitAction to
2704 waitIfPossible (was wait).
2706 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2709 CCL operator names may be set in field definition files (CCL_bibset).
2710 See ccl/bib1 for an example.
2712 Fixes in ASN.1 compiler for C++ compatibility.
2714 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2715 and "op_or" to avoid conflict with C++.
2717 Fixed problem with GNU readline detection on Redhat 7.0.
2719 Added step-size for Scan backend handler.
2721 Fixed bug that made the frontend server crash when no attribute
2722 set was specified for scan.
2724 Front-end server automatically switches to original working directory
2725 when installed as an NT service. Previously -w had to be specified to
2728 Added extended attributes for retrieval module (data1), so that data1
2729 records carry d1_readXML/SGML attributes. d1_read also supports
2730 null-data rules ( <tag/>)
2732 On UNIX when POSIX threads are available, a separate library libyazthread
2733 is created. Programmers should link with that library and the yaz library
2734 when using threads. The reason for the split was that some applications
2735 on Linux, such as Apache, doesn't work well when using shared objects that
2738 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2739 (or any frontend server) in SSL mode by specifying ssl: followed by
2740 address. Only tested on UNIX.
2742 Added feature for CCL module. Virtual structure s=al or s=ol generates
2743 and-list and or-list respectively instead of phrase search.
2747 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2748 log_mask_str. This was done to avoid name conflicts with other libraries
2749 (such as other PHP extensions).
2751 Added raw OID member for preferred record syntax (request_format_raw)
2752 and returned record syntax (output_format_raw) for backend fetch method.
2754 Config file yaz-config now accepts options so that it returns specific
2755 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2757 Shared library support for UNIX using GNU libtool.
2759 * Modified backend interface. Request/Response struct's replaced by
2760 one read/write C struct. For example bend_fetchrequest and
2761 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2762 Every handler - even search has to be registered in bend_init
2763 handler. This means that the YAZ library no longer refers to
2764 external functions and it makes it possible to make the whole
2765 thing a single DLL/SO.
2767 Added Segment handler for backend server.
2769 Added Zmbol/Zebra administrative functions to YAZ client.
2771 Threaded frontend server on UNIX (when POSIX Threads are available).
2772 Starting the server with option -T enables multi-threading.
2776 Added configure option --enable-comp/disable-comp to control use
2777 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2778 located in sub directory asn.
2780 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2781 in ${exec_prefix}/bin along with the other programs yaz-client and
2784 GNU automake used to maintain makefiles.
2786 Added several OID's.
2788 Changed retrieval module so that we can load records with no abstract
2789 syntax defined. Tagpaths in these records are fully composed of string
2792 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2796 On UNIX, the generated makefile now supports a proper 'make install'.
2797 The prefix can be set via GNU configure to set the install location
2798 (default is /usr/local).
2800 * YAZ programs client and ztest were renamed to yaz-client and
2801 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2802 locations, such as /usr/bin,/usr/local/bin,etc.
2804 * YAZ Header files were moved from include to include/yaz. YAZ Header
2805 files are referred to as include <yaz/log.h> rather than <log.h>.
2806 The YAZ include path (-I ..) is therefore the same as before. Programmers
2807 should update their #include statements or use -Ipath/include/yaz
2808 instead. The main motivation for doing this change is that YAZ header files
2809 can be installed in "standard" locations /usr/include,/usr/local/include
2810 without introducing conflicts, since ALL YAZ header files are stored
2811 in subdirectory yaz (under /usr/include for example).
2813 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2814 rather than project/workspace files. We switched because project files
2815 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2818 Changed name of logging function, logf, to yaz_log, to prevent name
2819 clash with some math-log functions. The YAZ header log.h defines logf
2820 to yaz_log (#define) so there should be no incompatibilities by this
2823 Added bend_start/bend_stop handlers for server. These handler are
2824 called on start/stop of server. For windows they are called whenever
2825 a service is started/stopped.
2827 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2828 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2829 in util/yc.tcl. The auto-generated C code structures are, in a few
2830 cases, incompatible with the old decoders. There are differences in the
2831 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2832 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2833 The preprocessor variable ASN_COMPILED is defined when the compiled
2834 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2835 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2836 wish to use the old encoders/decoders you can specify --disable-yc
2839 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2840 version so that it supports both new - and old version of DB Update
2842 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2843 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2844 change. The name parameter can be set to 0 in which no name is specified
2845 for the construction. The macros odr_implicit and odr_explicit sets name
2846 parameter to zero for the construction involved. New macros
2847 odr_implicit_tag and odr_explicit_tag are similar to the others,
2848 except that a name parameter is added. For programmers' that don't use
2849 ODR they probably only need to change the call to z_APDU and z_External.
2851 Added access control facility by interfacing the TCP wrapper library.
2852 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2853 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2854 name of the daemon and enables the access control as specified in
2855 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2857 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2858 den Dool <H.M.vdnDool@kub.nl>.
2860 Added reference ID parameter to most functions in server API - refer
2861 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2863 Changed name of ccl library to libccl.a (was ccl.a).
2865 Fixed bug in decoder for Explain (Category TargetInfo).
2867 Added support for GNU readline in client. Thanks to Jacob Poulsen
2868 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2870 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2871 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2872 IMPLEMENTATION! This change was made to the development version before
2873 the ZIG decided to retract the amendment. If any users MUST be
2874 compatible with the original Update definition, PLEASE CONTACT US, and
2875 we will include a separate definition corresponding to the old Update
2876 ES. Note that because of the change to the ASN.1 of the
2877 TaskPackageRecordStructure we cannot define a single structure that
2878 will support both versions.
2880 * Added const modifier to buffer parameter for some ODR/BER encoding
2881 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2882 completeWAIS, odr_dumpBER.
2884 Fixed bug in client.c which caused a crash when a scanResponse didn't
2885 contain positionOfTerm.
2887 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2888 * will cause an error in a client if a non-YAZ target sends both a
2889 * list of Scan entries and non-surrogate diagnostics.
2891 Retrieval module enhancements. Tag sets may be typed in the reference
2892 to it. From the .abs-file the "tagset" directive takes a third optional
2893 integer type for the tag set referenced. From a .tag-file the "include"
2894 directive takes a third optional type as well. The old "type" directive
2895 in the tag set itself is still recognized but acts as the default type
2898 Backend interface change. Individual Scan terms returned from bend_scan
2899 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2900 in include/backend.h.
2902 Retrieval module enhancements. Multiple tag sets and attribute sets may
2903 be specified in abstract syntax specs. Revised the error/warning for
2904 logging messages reported by the retrieval module when reading the
2907 Object Identifier system (oid_..) changed. The API is backwards
2908 compatible but the oid-routines now allocates new OID's when needed.
2909 Raw OID's may be specified in oid_getvalbyname.
2911 YAZ now uses GNU configure to generate Makefile(s).
2913 * Minor changes in some of the member names of DeleteResultSetRequest and
2914 DeleteResultSetResponse. See include/proto.h.
2916 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2917 and added member 'languages' in TargetInfo (which was missing).
2919 Changed the way attribute sets are handled in the retrieval
2920 module. These are now cached, just like the abstract syntaxes
2923 Changed YAZ so that it links with compiled ASN.1.
2925 Added Explain-schema definitions and mapping routines. The following
2926 Explain categories have been implemented: AttributeDetails,
2927 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2929 Fixed minor bug in Windows version of Server Library.
2931 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2933 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2935 Added EXTERNAL: UNIverse Resource Report (non-standard).
2937 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2938 ENUMERATED and SET OF.
2940 * Added 'const' to some of the char pointer arguments for the
2941 functions, data1_read_node, data1_getelementbytagname,
2942 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2945 Fixed bug in data1_insert_taggeddata - the last_child member of
2946 parent wasn't initialised.
2948 * Changed data1_read_record and data1_read_node so that the supplied
2949 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2950 doesn't refer to any parts of the "SGML"-buffer.
2952 Fixed bug in server library (Windows version of statserv_remove).
2954 * Changed code so that it compiles as C++. The type definition
2955 of Odr_fun which is a member of Odr_arm was changed. The result is,
2956 that an explicit typecast is needed for the fun pointer when
2957 using Odr_arm - as in:
2958 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2960 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2962 Implemented the new structured date and time definition as approved
2963 by the ZIG. Added schemaId element to the specificTag in Espec-1
2964 (also approved at the last ZIG). Thanks to RVDM.
2966 Added some Object identifiers (RVDM).
2968 Changed the Update Extended Service (RVDM).
2970 Added command "refid" to client which specifies referenceId for
2971 the following requests.
2973 Implemented extended service handling for server. See ztest.c
2974 for an example as well as backend.h. New handlers are registerd
2975 in the Init handler.
2977 * Changed interface for sort in server.
2979 Added new members to statserv_options_block. It allows a server
2980 to read options from another source than just the command line. Thanks
2981 to Charles Woodfield.
2983 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2984 renamed to zboolean. Some C++ compilers complained about the name.
2986 Minor changes to gils.abs. Added index 's' (sort) on title
2987 and date/time-last-modified.
2989 --- 1.4pl2 1998/1/30
2991 Fixed bug in server library regarding inetd mode (-i). This bug
2992 was introduced by release 1.4.
2994 --- 1.4pl1 1998/1/29
2996 Added sort facility in client and backend server interface.
2998 Fixed problem with dependencies in Makefile(s).
3000 Fixed bugs for encoders/decoders of extended services and
3003 Implemented sub-tree feature for schemas. Sub-trees are
3004 referenced in *.abs-files. See explain.abs for an example
3005 of the use of this feature.
3007 Modified bib1.att; local attributes for ANY didn't include
3008 ANY itself (only affects use of the retrieval module).
3010 Fixed bug in plain SGML reader in function data1_read_node:
3011 tags with prefix "var" was incorrectly interpreted as variants.
3013 Added feature "sub-schemas" to enable references to - and definitions
3014 of - group of elements.
3016 * Removed member parent from type data1_element (in data1.h).
3018 Implemented function odr_nullval() that returns the value of
3021 * Removed member num_children from data1_node (in data1.h).
3023 Made NT service interface part of the server library. The
3024 function statserv_main uses the NT service when required and
3025 calls the statserv_start / statserv_close routines.
3027 Routine zget_SearchRequest and zget_PresentRequest fills
3028 resultSetName/Id member with "default" instead of "Default".
3030 Fixed memory leak in server. Request queue member wasn't freed.
3032 Fixed nmem_exit so that memory is freed.
3036 Revised the CCL parser utility to be thread safe.
3038 Added function, oid_ent_to_oid, to replace the function
3039 oid_getoidbyent, which is not thread safe.
3041 * Added nmem_init and nmem_exit to initialize and release
3042 NMEM resources. Function nmem_init should be called once in the
3043 initial thread before NMEM/ODR is used. statserv.c and client.c
3044 have been changed accordingly. The change was necessary to make
3045 NMEM thread safe. The NMEM memory pool is shared amongst threads
3046 in a process. Unix-based applications will still work fine without
3049 Added NT Services interface for the the Z39.50 (statserv) Server.
3050 Refer to the ztest.c source on the usage.
3052 Windows 95/NT port using MSVC5.0. Project files are included in the
3055 * Defined new 'global' handle for the retrieval (data1) system. The
3056 new handled, data1_handle, describes the state of the data1 system.
3057 This handle is passed as first argument to virtually all
3058 data1 related routines. The functions data1_create and data1_destroy
3059 creates and destroys a data1 handle respectively.
3061 Added ODR encode stream member to all backend request structures
3062 init, search, scan etc. This stream should be used to allocate all
3063 memory used for the response when thread safe operation is needed.
3065 Changed the comstack utility, cs_addstr, to be thread safe. The
3066 returned hostname string returned by the function is now part the
3069 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3070 function. The cs_straddr takes a COMSTACK handle as argument, so this
3071 function must be used after cs_create and before bind/connect.
3072 This function is thread safe.
3074 Moved test server to 'ztest' directory - generic server code still
3075 in 'server' directory.
3077 Made prefix query (pquery.c) utility thread safe.
3079 Added new function modifier YAZ_EXPORT to 'export' public DLL
3080 functions when using windows (see include/yconfig.h).
3082 Added definitions to the OID database (util/oid.c) (RVDM).
3084 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3086 Added call to ccl_rpn_delete in client program.
3088 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3089 release of RPN structure.
3091 Added support for C++, headers uses extern "C" for public definitions.
3092 With input from RVDM.
3094 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3095 Thanks to Ronald van der Meer (RVDM).
3097 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3099 Added support for private extensions to the OID database
3100 (oid_setprivateoids()). Thanks to RVDM.
3102 Added optional, physical ANY (key replication)
3104 Fixed null-reference problem in GRS-1 output filter.
3106 Proximity operator added to Prefix Query Format (PQF).
3108 In test client command "base" accepts multiple databases.
3110 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3114 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3116 Smallish bug-fixes in the new encoders/decoders (explain).
3118 Bug fixed in DeleteRequest.
3120 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3122 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3124 Added SOIF syntax (using private OID for now) to retrieval module and client.
3126 Added Update extended service.
3128 Added SearchResult-1 additional info structure.
3130 Added optional CCL (ISO8777) interpreter as separate module. Available
3133 --- 1.2 1996/6/10 (1st anniversary release)
3135 Added Summary record syntax. Lightly tested.
3137 Added OPAC record syntax. Untested.
3139 Added ResourceReport service encoders/decoders. Untested.
3141 Fixed bug in z_Unit - wrong tagging on unitSystem.
3143 Fixed bug in the DiagRecs decoder.
3145 Added options for max PDU size and session timeout to frontend-server.
3147 Added documentation of query-language parsers and other supporting utilities.
3149 [frontend-server] Added Attribute set to the bend_scanrequest API.
3151 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3152 surrogate diagnostics were generated.
3154 [retrieval] Allow multiple local values for attribute.
3156 [retrieval] Allow multiple attributes per element in .abs files. index type.
3158 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3160 --- 1.1pl2 1996/4/10
3162 Minor changes, mostly specific to Zebra's requirements (retrieval)
3166 Repaired bug in frontend server when running multiple listening
3167 endpoints in dynamic mode.
3169 z_External() now won't break if a known, ASN.1 value comes encapsulated
3170 in an octet-string. The value will pass through unmodified in an Odr_oct.
3172 Added a bit of code to the demo client to decode & display
3173 ASN.1-structured records represented in the octet-aligned branch of
3174 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3176 Added z_ext_getentbyref() to the ASN module. Doc updated.
3178 * Completed the SCAN definition in the ASN module. This may break SCAN
3179 code based on older YAZ-versions at compile-time. The fix is easy -
3182 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3183 under the SCAN definition. Remember to initialize this, server-people.
3185 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3186 that this does not extend to ODR and ASN.
3188 Comstack allows insertion of established socket (primarily for
3189 inetd-operation of servers). Doc updated.
3191 Front-end server can now start from the inetd in TCP mode. Doc
3194 --- 1.0pl4 1996/1/24
3198 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3199 the rank and record number.
3201 Adjustments to the frontend server.
3203 Fixed diagnostic BER dumper. It ignored the file argument.
3207 Various changes to retrieval module.
3209 Changed the union discriminators of the protocol files from enums to
3210 ints paired with #defines.
3212 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3215 *Changed operator in the RPN structure to 'roperator', again to avoid a
3218 Fixed problems in Explain decoders/encoders.
3220 --- 1.0pl2 1995/12/6
3222 Memory bug in log module fixed.
3224 --- 1.0pl1 1995/12/5
3226 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3228 Bug in Explain DatabaseInfo module fixed.
3230 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3234 The shift to v1.0 signals that we now consider the *core* functionality
3235 of YAZ reasonably stable (the core being more or less equivalent to
3236 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3237 tested (Explain not at all - though that will happen soonish).
3239 Minor changes to code to support Windows port.
3241 Various minor changes after we're getting to use GRS-1 & co. more.
3243 Added Espec-1 format.
3245 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3246 of the protocol and it cannot be selected when encoding (maps into 'string'
3247 when decoding). Needed to talk to some servers.
3249 Demo client can request simple element set names.
3251 Added Diagnostic Format encoders/decoders.
3253 Added simple Close handling to frontend server (no hooks for resource
3254 reporting yet), and demonstration client.
3256 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3258 --- 1.0b3 1995/08/24
3260 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3261 handled incorrectly when records were requested in the searchResponse. This
3262 will only affect you if you use the frontend-server.
3264 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3265 Test-client will ask for and print GRS1. Ztest will return dummy records
3268 Added Explain encoders/decoders to the service-level API. Untested.
3270 Added Extended Services: Item Order encoders and decoders to the Service-
3271 level API. Untested. We could use a recent copy of the pertinent bits
3272 of the ILL protocol to add those bits.
3274 Added diagnostic format 1 encoders/decoders to the service-level API.
3277 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3278 odr_cons.c, which causes a more correct output.
3280 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3281 was always set to 0 when no records were requested in the searchRequest.
3283 * Added better external-handling. This shouldn't harm old code that
3284 *encodes* externals. It can break code that looks for a
3285 'single-ASN1-type' representation, since those types that are known
3286 are now decoded immediately. Look at the SUTRS sample code in
3287 seshigh.c and client.c. Documentation updated.
3289 Handling of structured records in bend_fetchresponse. Length -1 marks
3290 structured record, type is deduced from format field.
3292 --- 1.0b2 1995/06/27
3293 Fairly quick maintenance release to add SUTRS support.
3295 Fixed handling of SUTRS records in the demonstration client.
3297 * Added format field to the bend_fetchrequest and bend_fetchresponce
3298 structures of the backend API (frontend server). When the record is
3299 returned, the value of the format field is mapped to an OID. The
3300 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3301 of the record. The special value VAL_NONE in the bend_request means
3302 that no specific format was requested by the client. Documentation
3303 updated accordingly. Test server (ztest) will return a fixed dummy
3304 SUTRS record if your client requests SUTRS.
3306 Documentation updated accordingly.
3308 You can now set external libraries and RANLIB support in the top-level
3312 First public release.
