3 Implement Solr sort strategy "solr", similar to sru11 sorting.
4 This will implement the correct parameters on Solr requst to do
9 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
12 MARC: Extra/missing indicator handled for MARCXML.
13 The indicator length is given in header and is the same for the
14 whole record. If attributes ind1, ind2 are missing, then content
15 character defaults to blank. Extra indicator attributes (beyond)
16 indicator length are treated as an error.
18 Reformat: delete trailing whitespace
22 MARC: fix non-ASCII characters for leader. This is to ensure we can
23 generate XML in UTF-8.
25 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
26 in one node with structure word.
30 yaz-json-parse: JSON output may be pretty printed by using option
33 Increase default value of max message for Z39.50 Init for GFS, ZOOM
34 and yaz-client. Old value was 1 MB. New value is 64 MB.
38 yaz-client: don't display bogus records from SRU servers. Some SRU servers
39 return more records than given by *maximumRecords*. Skipping those in
42 record_render: simplify buffer return handling and fix at least one bad
43 memory reference, that broke the test_embed_record sometimes.
45 Allow http://user:pass@host notation for yaz_url_exec.
47 zoomsh: allow shell command to be executed. Via the system(3) call.
49 yaz_poll: Allow num_fds == 0
51 yaz-client: fix bad encoding of "itemorder item". The itemorder
52 item <no> - command forgot to use length of encoded Item Request
53 package. Error present since YAZ 3.
55 yaz-ztest: fix bad usage of session handle. Bug was introduced when
56 result sets were saved (271a9c83).
58 SRU recordPacking: guess record packing in response rather than looking
59 at the recordPacking element which, OF COURSE, changed semantics in SRU
62 Decode SRU 2.0 responses. The official namespace for responses, according
63 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
64 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
65 nature.com's server, however, usee namespace
66 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
67 we are now using a glob-expr to match up the namespace. ZOOM C and
68 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
69 I can not find a single real example showing the "real" namespace in
70 the documentation from OASIS. The namespace for requests is different
71 from responses, but this is not added to YAZ yet, when we don't encode
76 zoom/record_render: add support for Base64 decoding fo MARC records
77 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
78 which will decode base64 + ISO2709 marc-8 encoded material from text node
83 Add missing definitions ZOOM_resultset_get_facet_field_by_index
84 and ZOOM_resultset_facets_names.
86 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
89 Change APDU dump printing to avoid long leading blanks. For levels 16
90 or larger the level is shown and the indentation is truncated but
91 recursed with modula 8. This makes it still reasonable easy to read
92 - even for nested BER dumps.
94 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
95 return 0 (incomplete package) in case where the BER package was
96 considered too nested (return value of -2).
98 dumpber: lines of level 15 are not indented further. Two spaces per
99 indentation; indentation 15 or more is indented to a fixed indentation
100 and augmented with a level=<no> indication.
102 zoomsh: increase max size of command+args
104 GFS: No limit in RPN buf size in CQL to RPN conversion.
106 --- 4.2.33 2012/05/09
108 New function for daemon utility, yaz_daemon_stop .
110 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
112 --- 4.2.32 2012/04/25
114 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
115 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
117 --- 4.2.31 2012/04/23
119 YAZ daemon utility relays SIGUSR1 to child process.
121 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
122 would result in en empty database list - which in turn would result in
123 encoding failure for search.
125 Fix reading beyond string in yaz_sort_spec.
127 --- 4.2.30 2012/04/11
129 Add two new SRU diagnostics:
130 236: Access to specified database denied
131 1015: Init/AC: Maximum number of simultaneous sessions for Userid
133 Document the very useful ZOOM-C option "apdulog".
135 CQL to RPN: term may be passed through verbatim. This is enabled with
136 truncation.cql . The assumption being that the term is already CQL.
138 --- 4.2.29 2012/03/20
140 record_conv: leader spec may be given for marc element.
141 The leader spec is given as attribute leaderspec for element marc.
142 For example to convert a MARC21 record from MARC-8 to UTF-8:
143 <marc inputformat="marc" outputformat="marc"
144 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
146 record_conv: allow user-XSLT params. For example:
147 <xslt stylesheet="MARC21slim2DC.xsl">
148 <param name="myparameter" value="myvalue"/>
149 <param name="otherparameter" value="othervalue"/>
152 record_conv: fix error handling for missing marc charsets.
154 CQL: fix extra terms in wrong order.
156 --- 4.2.28 2012/03/06
158 record_conv: modify new API for conversion types. The conversion types
159 may be passed in new functions yaz_record_conv_configure_t and
160 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
162 Avoid mixed statement/variable declare; fixes compilation with Visual
165 --- 4.2.27 2012/02/28
167 Add non-standard SRU diagnostic: 235: "Database does not exist".
168 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
169 Update SRU to Bib-1 diagnostic maps accordingly.
171 CCL: add two new diagnostics for unsupported masking. The new
172 diagnostics are: "Embedded truncation not supported" and
173 "Single charcacter mask not supported".
175 --- 4.2.26 2012/02/23
177 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
179 --- 4.2.25 2012/01/11
181 Build YAZ for Ubuntu Oneiric.
183 CCL: allow parantheses for proximity operands. For example CCL query
184 (a) % (b) is now allowed.
186 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
187 marked dead, rather then being destroyed. If not, the session memory is
188 being free'd before the search/scan handler is finished. Also destroy
189 'request' memory in request_release rather than in various places,
190 which resulted in leaks from time to time.
192 --- 4.2.24 2011/12/21
194 cql_sortby_to_sortkeys: honor sort prefix.
196 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
197 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
198 The rpn2cql family of functions now always returns quoted CQL terms.
200 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
202 --- 4.2.23 2011/12/15
204 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
205 sequence is treated as one. For example, &&a=b&&&c& is identical to
208 --- 4.2.22 2011/12/05
210 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
211 APDUs for a connection to a WRBUF.
213 --- 4.2.21 2011/11/23
215 Fix cql_sortby_to_sortkeys. Completely broken before.
217 Make CCL's @truncation work again.
219 --- 4.2.20 2011/11/09
221 New ZOOM connection setting: tproxy. It's like proxy, but does not
222 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
223 to set resolved address + port for a connection outside ZOOM itself.
225 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
227 --- 4.2.19 2011/11/07
229 Fix uninitialized variable in Solr spell support (could cause SEGV
230 for SRU response decoding).
232 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
233 back-end's addinfo through into the ZOOM response addinfo.
235 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
236 they are separated by a colon and a space rather than simply
239 --- 4.2.18 2011/10/28
241 Add support for Solr spell-checking/suggestions through ZOOM.
242 If a Solr target has been configured correctly for spelling-checking
243 and suggestions, these will now be returned on the ResultSet option
244 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
246 --- 4.2.17 2011/09/28
248 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
249 with a flag whether to substitute escape sequences or not.
251 --- 4.2.16 2011/09/22
253 Fix nmem_strsplit_escape to substitute escape char properly.
255 New option for zoomsh -e , which makes it abort on first error and
256 return process exit code to indicate success/failure.
258 YAZ options utility supports special option -- which makes all it treat
259 all following arguments as non-options.
261 --- 4.2.15 2011/09/16
263 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
264 searched if absolute filename is given.
266 Fix conv_xslt() error-reporting when stylesheet is not found.
267 (The value of fullpath is meaningless in this situation.)
269 --- 4.2.14 2011/09/07
271 Fix problem in CQL sort node creation: un-initialized memory.
273 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
274 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
275 CQL sortby depending on whether Type-1 or CQL is actually sent to the
278 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
279 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
281 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
282 will make it possible to use both single-character mask (#) and wildcard (?)
283 in CCL . Throw diagnostic for left truncation because that is not supported
286 --- 4.2.13 2011/09/01
288 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
289 cases using escapes (\-sequences) and masking.
291 PQF parse fix: A trailing backslash followed by end-of-string (\0)
292 would result in a read one byte beyond string.
294 rpn2ccl may use Z39.50 masking for terms (t=z).
296 ICU check fix. Don't include library -lCrun on Solaris, unless present.
298 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
299 not --cppflags (which seeems like an error in icu-config).
301 --- 4.2.12 2011/08/27 RPM package only
303 cql2ccl: fix conversion of terms: operator characters were not
306 --- 4.2.11 2011/08/25 RPM package only
308 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
309 CCL parser will map both # and ? to their regular expression
310 quivalents (. and .*).
312 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
313 of reserved CQL characters.
315 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
316 is, so that they are passed through.
318 --- 4.2.10 2011/08/24
320 ZOOM SRU mode: more aggressive re-connect.
322 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
323 made available as a utility function, declared in <yaz/logrpn.h>
325 rpn2cql_structure() supports proximity nodes (except that the Type-1
326 proximity node's "exclusion" binary is ignored, as there is no way to
327 express that in CQL). Fixes bug #4564.
331 Fix SEGV that could occur if set command of zoomsh was given without
332 value (2nd argument).
334 Fix SEGV that could occur if unsupported transport was given for
335 COMSTACK - say https (when SSL was unavailable).
337 Build yaz-url on Windows too.
341 New utility to get web content. Header is url.h. A command line tool
342 yaz-url is part of the distribution and packages.
344 Fixes for SSL COMSTACK (when gnutls is in use).
346 New functions yaz_base64{encode,decode}. Header is base64.h.
350 ZOOM C includes HTTP response buffer as additional info if it fails
351 to decode the SRU response.
353 Make wrbuf_json_puts available.
357 zoom: throw diagnostic for invalid value for option "sru". Before a
358 bad SRU request was sent.
360 Adding new utility wrbuf_vp_puts.
362 Add cclxmlconfig.obj to win/makefile. It was missing completely.
366 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
367 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
368 redirect was used at the same time.
370 MARC line mode decoding: be less picky about length given - first
371 5 digits of header that is.
373 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
375 Changes to decoding of SRU records: a record with recordPacking=xml is
376 modified with a new root element <yaz_record> if the recordData contains
377 multiple children elements. This is to make the record XML parseable
380 RPN to SOLR conversion: encode special characters.
382 Generic Frontend Server: fix uinitialized member, stepSize.
386 Fix a bug in SRU decoding of records.. The database records stored
387 had un-initialized memory, but it would only be seen with yaz_record_render
388 and type_spec="ext" .
390 Fix a bug in ccl_qual_dup introduced in 4.2.3.
394 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
398 Add new utilities to convert from CQL to CCL . These utilities have
399 prefix cql_to_ccl defined in cql.h.
401 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
402 lead to memory heap corruptions when ICU utilities were in use.
406 Make compilation work without Libxml2.
408 yaz-client: remove redundant blanks in display of searchResult-1 term
413 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
414 resulting CQL node (tree) in a new node CQL_NODE_SORT.
416 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
417 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
418 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
419 Note that the CQL sortby spec is only converted when the GFS is already
420 converting from CQL to RPN (cql2rpn element).
422 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
423 specify whether to collapse delimitors or not. The existing nmem_strsplit
424 do collapse (collapse parameter = 1).
426 Windows installer: For NSIS, set InstallDir depending on x86/x64.
428 Rename internal func yaz_use_attribute_create. While non-static, this
429 function is not declared in a public header.
433 Add -lCrun when linking with ICU on Solaris.
435 More quicks character set conversions for OPAC records.
439 fix problem with record_render: records were converted (character set
440 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
444 SRU: add methods for handling DADS SRU-proxy facets.
446 Separate OPAC record character set for ZOOM_record. yaz_record_render
447 allows a character set given as charset=from/opacfrom,to where 'from' is
448 the character set of a bibliographic record, 'opacfrom' is character set
449 of OPAC record and 'to' is the target character set.
453 yaz-client: show may XML format records. Command show followed by 'format'
454 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
457 src/stemmer.c: Avoid using unnamed union. It is not supported by some
460 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
463 Update yaz.spec to operate on both SLES11 / Centos 5.5.
465 RPM: Release includes 'indexdata' name. Use indexdata in release name so
466 this package can be distinguished from other vendors.
468 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
469 as determined by configure
471 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
473 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
474 returns no error and no record, the present request is considered
475 partial (only a subset of the records could be returned by backend), and
476 so it is appropriate to set Present Status to partial-4.
480 Move yaz-config man pages to section 1.
482 More documentation about SOLR.
484 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
485 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
486 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
487 peers on some Linux systems. However, in general that does not work
488 so YAZ can not rely on that to work. Debian changed behavior in this
489 respect from Debian lenny to Debian squeeze (still testing as of Oct
491 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
493 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
497 Fix yaz-config output: echo_source not set correctly by configure.
501 SOLR WebService support for yaz-client and ZOOM.
503 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
505 --- 4.0.12 2010/08/17
507 Z39.50 facet support. Facet specifications are passed for search in
508 other-information with ASN.1 as defined in facet.asn and OID
509 .10.1000.81.5 . Facets are expressed as an Attribute list as known
510 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
511 3 is limit (number of entries to get in response). yaz-ztest returns
512 dummy facets if a client asks for them.
514 --- 4.0.11 2010/07/09
516 CCL fixes: bug 2895 and bug 3539.
518 GR1-display: add comma in display - was removed by mistake in
521 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
523 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
525 --- 4.0.10 2010/06/18
527 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
528 result set from a connection. The result set will be on its own
529 thereafter; no operations on it will perform retrievals from a target.
530 Only cached copies are returned.
532 ZOOM C:fix case for HTTP servers responding with Connection:close.
533 Ensure that if there is a current task it is resumed (like fetching
534 more records in a result set) . Bug #3484.
536 PQF parser: use odr_atoi for Odr_int (not atoi)
538 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
539 values that contain any non-digits are treated as string attributes
540 (previously decoding only checked for leading character ([0-9]). PQF
541 encoding: attribute string values are not surrounded by double-quotes.
545 New utility for managing threads - thread_create.h.
547 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
548 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
549 but YAZ' implementation do.
551 Fixes for yaz_cond-functions on Windows 7.
553 DLL export more symbols.
555 zoomsh: show record do NOT render opac.
557 Remove *.la files from Debian and RPM packages.
561 Debian package libyaz-dev depends on libgnutls-dev again (was
562 removed in YAZ 4.0.6, but due to Libtool it is still needed
563 even though yaz-config do not list libgnutls libs).
565 ZOOM: Use only one WRBUF for returning string results for
566 ZOOM_resultset. Reduces memory usage for ZOOM in general.
568 ZOOM: ZOOM_connection do not use a shared pointer to
569 ZOOM_resultset after ZOOM_resultset is destructed by
570 user. Reverts to YAZ 4.0.4 behavior.
574 record-conv: fix problem with at least one XSL conversion -
575 due to probably incorrect usage of XML XSL documents.
579 Fix yaz-config for static mode and the use of SSL (gnutls).
583 Forward decl timeval struct in mutex.h and gettimeofday.h.
585 yaz-config: fix 'static' mode linking.
589 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
590 are wrappers for pthreads or Windows. For Windows these are put in
591 a separate DLL: yaz_cond4.
593 libyaz.la (whole source) is compiled with thread. If thread support
594 is enabled enabled, all source of YAZ is compiled with treading support.
595 This allows core utilities such as yaz_log to use thread facilities.
596 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
597 thread utilities. This commit moves mutex utilities (mutex.c) from
598 libyaz_server.la to libyaz.la.
600 yaz-json-parse displays leading text until error.
604 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
605 patch from Giannis Kosmas.
607 SRU: no longer URL encode SRU database. The URL for an SRU server is
608 a URL and such is alreeady encoded - at least when given with leading
609 http:// or https://. This reverts behavior to YAZ 3.0.50.
611 Support for new MARC XML notation TurboMARC which like MARCXML is a
612 complete representation of MARC/ISO2709.. This one, however, is more
613 compact and allows for faster processing with XSLT. TurboMARC can be
614 used in the marcdisp.h API, from the yaz-marcdump utility and from
617 yaz-ztest can be configured - via the database - to perform certain
618 delays when it performs operations search, present and single record
619 fetch. This allows testers to make yaz-ztest act as a real or even slow
620 Z39.50 server. Refer to the yaz-ztest man pages for details.
624 wrbuf_destroy allows NULL WRBUF passed to it.
626 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
628 Add ZOOM_connection_close.
630 No fixed size buffers for ZOOM shell - bug #3257.
632 tstodr: make it work on s390 platform.
634 New icu iterator-functions. The new icu_iter-functions makes it possible
635 to use ICU chains from many threads.
637 yaz-client: better syntax check for show command.
641 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
644 New simple local-file XML include facility which allows file glob-patterns.
645 Refer to yaz/xml_include.h.
647 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
650 ZOOM_record_get supports new parameter "format" which makes it format XML
653 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
654 JSONText in ECMA-262) is JSONValue, not JSONObject.
658 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
659 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
661 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
662 POSIX/Unix builds .so with major version 4.
664 Remove old LOG_-defines from log.h. They have been obsolete and
665 undefined by default for the last 5 years.
667 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
669 GFS: Remove socket (int *fd) from search_rr handler. The socket
670 descriptor ptr is a facility that allowed a search handler to supply
671 a socket which would serve as a callback - when search was complete.
672 This facility has now been in use for years.
674 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
675 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
676 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
677 returns 'const char *' rather than 'char *. The returned string is
678 read-only and should not be modified by applications. COMSTACK cs_close is
679 now a void function - it no longer returns int. No applications check for
680 the value and the implementations has always returned 0.
682 ZOOM: use size_t for scan hit counts and str size. Functions
683 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
684 occ (hit count) and len (string length) are now of type size_t pointer
685 rather than int pointer. This is to be able to represent large hit counts
686 and to also just to use the proper type for string length (strlen result).
688 New JSON parser. Refer to include/yaz/json.h .
690 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
691 Used to be int in some cases. Many wrbuf_-functions used to return an int
692 indicating some length.. These return values were never used. And so they
695 ODR: odr_malloc, odr_total now takes size_t for size.
697 clone_z_type: fix leak; occurred for encoding failures.
699 --- 3.0.52 2009/12/03
701 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
702 bug was introduced in 3.0.51.
704 --- 3.0.51 2009/12/02
706 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
708 tcpip comstack: fix leak for getaddrinfo.
710 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
711 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
712 Decoding of SRU "path" database is performed by private function
713 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
714 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
716 yaz-client: honor base command for SRU. Change when database setting
717 is applied for SRU and ensure it is kept when a connection is reset.
718 Change also the way errors are displayed or SRU (decoding of packages).
720 --- 3.0.50 2009/11/02
722 Add support for extra request / response data for SRU codecs and GFS.
723 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
724 for extra data response buffer and length. For the GFS, both request
725 and response data (XML) is carried in extra_args and extra_response_data
726 for the search handler. Patch by Ko van der Sloot.
728 ZOOM: For queries that cannot be converted to the specified rpnCharset,
729 ZOOM now returns a diagnostic on the client-side ('invalid query' /
730 10010). This fixes bug #2113.
732 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
733 cmdfile included a 'quit' command that would result in a memory violation.
735 --- 3.0.49 2009/10/01
737 Make a number of functions defined in xmlquery.c static. These have
738 never been declared in a public header file (yaz/xmlquery.h) and was
739 made public by mistake.
741 Improve speed of character conversions (iconv utilities). This makes
742 conversions from MARC-8 faster.
744 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
745 unless type desired is "raw". This will prevent type "xml" from
746 returning ISO2709 .. Which obviously can not be XML parsed.
748 Fix memory leak in ZOOM that would occur if option apdulog was used
749 on a re-used connection.
751 Frontend server logs HTTP requests.
753 Frontend server now sends Z39.50 close when it times out (sesssion has
754 been idle for too long). Versions 2.0.30 and earlier also sent close.
755 But due to a mistake this was disabled in all versions after that, i.e.
756 the server would just close the socket immediately.
758 yaz-client emits a better message when receiving an unrecognised
759 userInformationField.
761 Skip zero-length subfields when decoding ISO2709. This rare case happens
762 if a record has two FS characters in a sequence. Without this patch
763 there would be a reference beyond char array in using_code_len fragments
766 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
768 --- 3.0.48 2009/08/28
770 The show command offered by the zoomsh command now takes a 3d optional
771 parameter type which is what is passed to ZOOM_record. If the type
772 argument is omitted, "render" is used.
774 RPN to CQL conv may use USE string attributes (bug #2978).
776 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
778 --- 3.0.47 2009/07/08
780 Function yaz_xml2query allows a diagnostic element in the PQF XML
781 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
782 code and additional info respectively.
784 The BER BOOLEAN is now the integral type Odr_bool which still happens
785 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
786 typedef'd to Odr_int. This is still an integral 'int', but it may be
787 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
788 ASN-1 compiler as well as programs has been updated to use the new types.
790 --- 3.0.46 2009/06/08
792 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
793 only the bibliographic record was rendered. For type=opac, an OPAC
794 record is only returned if it is present.
796 iconv: small fix for encoding of advancegreek.
798 yaz-client: avoid double display of SRU/SRW records (bug #2798).
800 yaz-client: option auto_reconnect=on really reconnects.
802 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
804 server: avoid null ptr ref for for yaz_poll errors.
806 build: fix RPM build for RHEL 5.3.
808 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
810 --- 3.0.45 2009/03/31
812 Fixed bug #2709: TCP connect returns Invalid argument.
814 Fixed compilation for mingw.
816 Honor charset for raw records (ZOOM_record_get).
818 Fixed use of errno for threaded mode that was seen on Solaris 10.
820 Fixed argument passing with blanks in value for Windows Service.
822 Disable YAZ' own log rotate by default (no 1 GB limit).
823 The variable l_max_size which specifies the log file limit is set to 0
824 (DISABLED): This is due to the fact that YAZ is most often deployed using
825 logrotate. Also YAZ can not perform log rotate because of unsufficient
826 permissions (setuid).
828 --- 3.0.44 2009/02/17
830 List supported encodings in man page for yaz-iconv.
832 Fixed missing SSL libs for --libs output
834 Re-established OID record syntax application-xml. Nobody should use it
835 but we don't want to change soname because of this symbol being absent.
837 --- 3.0.42 2009/02/02
839 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
841 Added member named_result_sets for init handler struct for the GFS. This
842 allows a server to disable named result sets.
844 Removed OID record syntax application-xml.
846 Added support for rule-based transliterator for ICU wrapper of YAZ.
848 Fixed bug #1902: yaz-icu XML output.
850 Make YAZ checks Emacs friendly.
852 BITSTRING value shows value. Bug #2346.
854 ISO2709 decoding: skip control characters from indicator data.
856 Omit sort key by default in yaz-icu's output.
858 Allow combined single char options (again) for YAZ' options function.
860 Utility yaz-marcdump got option to display YAZ version (-V).
862 Allow YAZ to use ICU 3.4.
864 Added new ICU test case which illustrates removal of diacritics.
866 --- 3.0.41 2008/12/29
868 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
870 --- 3.0.40 2008/12/29
872 For configure, using option --without-xml2 also disables Libxslt/Libexslt
875 Fixed bug #2352: yaz-marcdump crashes for certain record.
877 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
879 Added support for Danmarc2 to UTF-8 conversion.
881 Added support for ISO5426 to UTF-8 conversion.
883 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
884 implementation version.
886 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
888 --- 3.0.38 2008/11/10
890 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
891 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
893 ZOOM C now interprets databaseName option for ZOOM connection as path
896 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
898 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
900 Dummy Libxml2 types no longer defined in headers of YAZ'.
902 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
905 --- 3.0.36 2008/09/26
907 Various ODR chapter fixes.
909 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
911 Added missing source for Windows compilation, mutex.c.
913 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
915 For SRU connections in ZOOM all records up to "count" are now fetched.
917 Fixed crash in generic frontend server (and yaz-ztest) which occurred
918 in Windows due to bad error handling for Libxml2.
920 Added facility for sending arbitrary records (ASN.1 any) using
921 ZOOM C's Extended service update. Patch by Sam Reynolds.
923 New options for ZOOM C's connection, logapdu which makes ZOOM log
926 --- 3.0.34 2008/06/18
928 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
930 --- 3.0.32 2008/06/12
932 Fixed memory violation that could occur when decoding UTF-8. This bug
933 was only present in 3.0.30 of YAZ.
935 --- 3.0.30 2008/06/06
937 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
938 GNU TLS is used by default (if found).
940 yaz-ztest returns OPAC records if a client asks for OPAC.
942 Improved speed of MARC-8 encoding.
944 Added support for lossy and loss-less MARC-8 encoding.
946 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
948 Added new Windows Service wrapper (sc).
950 yaz-client's itemorder command may now send a file.
952 Fixed yaz-marcdump to allow the use of NS prefix for record element.
954 Added new function yaz_log_xml_errors.
956 Allow (but warn) unknown XML attributes in MARCXML parsing.
958 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
960 The UTF-8 to MARC-8 conversion now uses a different set of characters
961 for Greek symbols. Bug #2120.
963 --- 3.0.26 2008/02/21
965 Added yaz_daemon (daemon.h).
967 Fixed bug #2068: pkg-config trouble
969 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
971 --- 3.0.24 2008/01/28
973 Document --with-xml2 option.
975 Added OPAC XML XSD (etc/opacxml.xsd).
977 Allow glob mask for name attribute in retrieval element for the
978 generic frontend server's retrieval facility.
980 Changed yaz_poll_poll to return yaz_poll_except for all returned events
981 except POLLIN/POLLOUT.
983 Fixed error handling in cs_listen. Bug #2037.
985 --- 3.0.22 2008/01/20
987 Fixed version in yaz/yaz-version.h.
989 Fixed bug #2027: Crash when closing connection.
991 Changed configure so that ICU support is only enabled if only ICU
992 and Libxml2 is available (because the ICU chain is XML based).
994 --- 3.0.20 2008/01/15
996 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
997 is built. Only this DLL depends on the ICU runtime.
999 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1000 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1002 Changed license of CCL module to 'Revised BSD'. After consultation with
1003 remaining members of the original EUROPAGATE consortium, we are re-issuing
1004 the CCL module without a separate license. The software was developed by
1005 Index Data as part of a research project. The special license was included
1006 to help feed usage information back to the project consortium to support
1007 project evaluation. At this time, the project consortium has long-since
1008 disbanded, and the majority of the original principals have retired. At the
1009 same time, we have significantly modified the software during the following
1010 years, to the point where very practically no original code remains. To
1011 simplify re-use of the software, we have contacted those members of the
1012 consortium who could be reached, and agreed to re-issue the module as a
1013 proper part of the YAZ package.
1015 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1017 CQL closer to being version 1.2 compliant. CQL also allows free-form
1018 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1021 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1022 bug could make Extended services handling crash in the ZOOM layer. This
1023 bug was only present in YAZ 3.0.18.
1025 --- 3.0.18 2007/12/19
1027 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1030 yaz-marcdump reads and writes collection wrapped records.
1032 Handle OPAC for record conversion module.
1034 Fixes for ICU wrapper.
1036 Allow ICU libs to be controlled with --with-icu .
1038 --- 3.0.16 2007/11/12
1040 Added yaz_poll which is a wrapper for select/poll. When poll is available
1041 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1042 sockets to be in use.
1044 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1045 functionality through an XML based configuration (ICU chain). This system
1046 is useful for search facilities such as Pazpar2 and Zebra that needs to
1047 perform tokenization of indexed material. The ICU code in a separate
1048 library libyaz3_icu.a.
1050 Added HTTP tunnel facility for COMSTACK, bug #1752.
1051 This is a facility that allows a Web proxy, such as squid, to tunnel
1052 Z39.50 traffic. This facility is "transparent" to must applications
1053 using YAZ. It's enabled by using pseudo transport connect: followed by
1054 the proxy address, followed by command, then follwed by he regular
1055 "virtual" addresss. For example,
1056 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1058 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1060 --- 3.0.14 2007/09/21
1062 Fixed bad memory reference in ZOOM_record - cuased by member not being
1063 initialized. This was a problem only in YAZ 3.0.12.
1065 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1066 fields were not removed.
1068 Changed the way C code is generated from codetables.xml. Made a MARC-8
1069 conversion trie for each characterSet section rather than codeTable.
1070 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1071 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1073 --- 3.0.12 2007/09/12
1075 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1076 from ZOOM_record_error).
1078 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1080 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1082 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1084 Better SRW-to-Bib-1 diagnostic mapping.
1086 ZOOM C and yaz-client announces SRU version 1.2 by default.
1088 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1091 Fixed in yaz_sru_decode to allow other version than 1.1.
1093 --- 3.0.10 2007/08/22
1095 Added support for SRU scan for ZOOM.
1097 Added support for the use of the older versions or Extended Service
1098 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1099 set to the version , 1=first, 2=second, 3=third. The third version is
1100 what ZOOM C has used so far. And that, obviously, is the default.
1102 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1103 therefore in Zebra and in SimpleServer-based applications). The new
1104 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1105 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1106 which is passed into the back-end search callback function.
1108 Added support for HTTP Basic authentication in clients: the SRU/W
1109 codec encodes the username/password elements of the PDU structure
1110 appropriately, and these may be set using the "user" and "password"
1111 options in ZOOM-C applications (the same options that are used for
1112 Z39.50 authentication).
1114 --- 3.0.8 2007/06/25
1116 Fixed bug #1208: SSL appears to be broken in ZOOM.
1118 Fixed bug #1206: Libxml2 include path weirdness.
1120 Added oid_name_to_dotstring.
1122 Allow elementSetName to be specified for ZOOM C record update.
1124 Allow waitAction to be specified for ZOOM C based for Extended Services.
1126 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1127 syntax OID. Bug introduced in YAZ 3 series.
1129 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1131 --- 3.0.6 2007/06/06
1133 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1134 directory. yaz-client now reads commands from file given by option -f
1135 if specified; then tries to read .yazclientrc in current directory.
1136 Failing that, it reads .yazclientrc from user's home directory.
1138 Added support for correlationInfo Note and ID for Record Update via
1141 Added yaz-client command querycharset which specifies character set for
1142 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1143 (termListAndStartPoint).
1145 Charset ISO5428:1984 is an alias for ISO5428-1984.
1147 Implemented a way to perform scan in a result set using Z39.50. This
1148 is achieved by attaching the result set name in the characterInfo
1149 (type InternationalString) of OtherInformation in the Scan Request PDU.
1150 The result set is identified in the otherinformation by the new OID:
1151 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1152 This allows for scan in result set and faceted search . Zebra did some
1153 of this in the APT term using attribute type 8 and value being result
1154 set. Using the OtherInformation approach for this is cleaner and easier
1155 to work with in proxies and the like. This facility can be used in
1156 yaz-client using new command setscan which takes a result set as first
1157 argument, start position (APT) as second.
1159 Changed decoding of SRU XML packed records to deal with servers that
1160 have recordData with XML data with multiple root nodes. Also make
1161 comparison for recordPacking case insensitive. Again, one server
1162 returns "XML" where others return "xml".
1164 For SRU responses allow Content-Type application/xml as well as text/xml.
1166 --- 3.0.4 2007/05/21
1168 Fixed bug in character set conversion of BER strings. Bug introduced
1171 --- 3.0.2 2007/05/08
1173 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1175 For OID class, use oid_class consistently.
1177 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1180 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1181 character set for bibliographic information interchange". By Giannis Kosmas.
1183 Added documentation on new OID API.
1185 --- 3.0.0 2007/05/02
1187 Changes to generic frontend server interface: added new member
1188 'query_charset' for bend_initrequest structure. A backend init handler
1189 should set this member to its native character set for query terms.
1190 When defined, the frontend server logic will announce this character set
1191 to a client if the negotiationModel bit is set by the client. All server
1192 implementors are encouraged to specify this. If a backend server does not
1193 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1195 Added CCL utility to remove terms (stop words) from resulting RPN
1196 tree. This is handled by functions with prefix ccl_stop_words_ .
1198 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1199 terms in RPN queries.
1201 Clean-up the CCL API. Moved some internal structures from ccl.h to
1202 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1203 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1204 This is replaced by ccl_parser_find_str which takes a string instead.
1206 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1207 libyaz.la is the core of YAZ except the generic frontend server and
1208 does not depend on POSIX threads anymore. libyaz_server.la is the
1209 generic frontend server facilities and uses POSIX thread functionality
1210 if available. The libyaz.la no longer depends on POSIX threads because
1211 the number of global structures is limited. NMEM no longer re-uses blocks
1212 between threads ; it simply free's memory immediately but allocates in
1213 "large" chunks as usual. We don't expect any performance penalties
1214 because of this. The yaz_log system is still using a global log_level so
1215 caution must be taken when modifying it with yaz_log_init_.. +
1216 yaz_log_mask_str. This, however, should not cause any trouble because
1217 these functions are called during initialization of application code
1218 anyway. `yaz-config --libs server` returns libs for server applications;
1219 `yaz-config --libs` returns libs for non-server applications.
1221 New OID database - with public definitions in oid_db.h. Removed old OID
1222 database including the head oid.h and definitions such as enum oid_value
1223 and struct oident. The new OID database uses the same string names as
1224 before but the 'protocol' is gone. There are now only two representations
1225 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1226 converts from string to OID; functions with prefix yaz_oid_to_string
1227 converts the other way.
1229 Change to emit_term() in CQL-to-PQF query translation: when a term has
1230 the /regexp relation modifier, do not process it for leading and
1231 trailing "^" and "*", which have quite different meanings in regular
1234 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1235 write handlers no longer carries a 'last' parameter. This will make
1236 yaz_iconv flush "less" characters. A flush is performed by call to
1237 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1239 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1240 removed, because function yaz_query_to_wrbuf does the same.
1242 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1243 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1245 Deprecated MARC utility functions removed.
1247 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1250 Branch split: YAZ_2_1_55_branch
1252 --- 2.1.54 2007/03/16
1254 Fix to ZOOM-C so that transparent reconnection is properly handled on
1255 connections that are in asynchronous mode.
1257 Fixed compilation on OpenBSD 4.0.
1259 Large strings in GRS-1 records are now properly displayed in yaz-client.
1261 Added character conversion support for "advancegreek"; based on patch from
1264 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1265 sequence is met. Before the error was not set so it would be unknown.
1267 Adjust yaz-marcdump MARC reader so that it skips until record separator
1270 --- 2.1.52 2007/03/07
1272 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1273 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1274 fd_set structure used as a bitmask for the FDs to be selected on.
1276 Using ACX_PTHREAD macro to check for POSIX threads.
1278 Fixed have-vsnprintf check.
1280 --- 2.1.50 2007/02/23
1282 Fixes for configure on BSD. Bug #900.
1284 Added snprintf/vsnprintf wrappers for systems that don't have
1285 limits (heavens forbid).
1287 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1288 created before all previous tasks were completed and removed from the
1289 task queue, the new task could be removed by a mistake.
1291 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1293 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1295 Fixed bug #832: Problem with MARC/charset in yaz-client.
1297 Fixed bug #668: save command line history for yaz-client.
1299 Fixed bug #830: pkg-config support.
1301 --- 2.1.48 2007/01/23
1303 Extended ZOOM result set options with two options that may be read by
1304 a client: resultSetStatus and presentStatus with values as specified for
1306 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1308 Fixed bug #827: Using SSL fails on Debian etch.
1310 Fixed bug #826: Weird looking chars for set of MARC records.
1312 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1313 that is treated as an ItemOrder with itemRequest being an XML document
1314 external. The value of "doc" is the content.
1316 Extended the GFS search facility. New member of bend_search_rr
1317 'estimated_hit_count' signals that hits is known to be an estmate
1318 (higher or lower than real hit count). New member 'partial_resultset'
1319 signals that the search was partial (hit count is lower or equal than
1320 real hit count). For Z39.50, the information is stored in resultSetStatus
1321 member of SearchResponse APDU. For SRU, the information is signalled
1322 via SRU diagnostic 59: "Result set created with valid partial results
1325 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1327 --- 2.1.46 2007/01/13
1329 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1331 Added ZOOM_connection_peek_event.
1333 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1334 the following new functions:
1335 ZOOM_event_nonblock, ZOOM_connection_process,
1336 ZOOM_connection_get_{socket,mask,timeout},
1337 ZOOM_connection_fire_event_{timeout,socket}.
1338 The existing blocking event handler, ZOOM_event, is a wrapper for the
1339 + blocking ZOOM_event_sys_{poll,select}.
1341 Implemented function ccl_xml_config which parses XML version of CCL
1342 configuration (bug #798).
1344 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1346 Added timings utility (yaz/timing.h)
1348 --- 2.1.44 2007/01/03
1350 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1353 Fixed bug #779: Rotation of apdu.log fails.
1355 Fixed for character set conversions:
1356 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1357 Honor G1 set in MARC-8 decoding.
1359 --- 2.1.42 2006/12/17
1361 Fixed bug #775: char conversion does not handle Alternative UTF-8
1364 Implemented function yaz_marc_read_line which parses MARC line format
1365 records. There is a wealth of formats out there. So far, this function
1366 reads line records produced by yaz_marc_write_line.
1368 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1369 more generic and easier to remember(!) options: -i format and -o format
1370 which specifies input format and output format respectively - where
1371 format is one of "marc", "marcxml", "line", "marcxchange".
1373 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1374 does not print anything except warnings for records.
1376 For yaz-marcdump, added support for MARC split into files (-s) with a given
1379 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1380 spec, at http://www.loc.gov/standards/sru/record-update/
1381 This has changed the binary layout of the following structs:
1382 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1383 bend_update_rr . Patch by Ko van der Sloot.
1385 Added GFS utility function bend_assoc_is_alive which returns 1 if
1386 association is still alive (client is connected); 0 otherwise (client
1387 closed connection). This allows busy servers to stop working for
1390 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1391 been a separate piece of software. This version of ziffy has been modified
1392 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1394 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1396 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1397 Client code may now interrogate options such as "init_opt_sort" to
1398 find out whether the server claims to support various options.
1400 --- 2.1.40 2006/11/27
1402 Added utilities yaz_{set,get}_esn to set/get element set name from
1405 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1406 of YAZ and has been so since YAZ 2.1.10.
1408 Implemented ZOOM_record_error which returns error information for
1409 record (surrogate diagnostic).
1411 --- 2.1.38 2006/10/31
1413 Updates for SRU Update by Ko van der Sloot:
1414 1. Changed name from "operation" to "action"
1415 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1416 versions in the code, marked as 'backward compatible'.
1417 3. Added diagnostics for SRU Update.
1419 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1421 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1423 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1425 For GFS, fixed problem with SRU diagnostic 'First record position out of
1426 range' being issued for 0 hits.
1428 zoomtst10 part of Windows Build.
1430 --- 2.1.36 2006/10/13
1432 Implemented yaz_filepath_comp which splits a path into file path
1433 components (required by Zebra 2.0.3+).
1435 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1436 BSD inspired license until now so this should not have any real impact on
1437 anybody. See http://www.opensource.org/licenses/bsd-license.php
1439 Fixed bug #687: Missing log lines.
1441 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1444 Fixed bug #689: SRU diagnostics to be added.
1446 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1447 whether a connection is idle (no more work do do).
1449 --- 2.1.34 2006/10/04
1451 Change type of optval from long to int for invocation of setsockopt with
1452 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1454 Added support for specifying the max log file size for the Generic
1455 Frontend Server. The size is given with option -r.
1457 --- 2.1.32 2006/09/21
1459 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1461 --- 2.1.30 2006/09/17
1463 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1466 Fixed bug in Generic Frontend Server that could cause a server to stop
1467 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1469 For the generic frontend server, the maximum record size is used as maximum
1470 size of incoming packages (SRU + Z39.50). The value until was previously
1471 only used in Z39.50 Init negotiation and, later, in a session controlled
1472 sizes of records returned. This is controlled using -k option. It can be
1473 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1475 --- 2.1.28 2006/09/04
1477 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1480 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1482 New option for yaz-marcdump -lpos=value which allows setting a portion
1483 of MARC header to a certain value.
1485 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1487 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1488 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1490 --- 2.1.26 2006/08/15
1492 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1495 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1497 --- 2.1.24 2006/08/08
1499 Fixed MARC ISO2709 encoding routines to deal with character set
1502 Minor changes to GFS logging. Database included in search request log
1505 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1506 cached/multiple records.
1508 Shared libraries are built by default on Unix+configure.
1510 Changed cql2pqf transformation to use a different evaluation order. The
1511 new order is: always, relation, structure, position, truncation, index
1512 and relationModifier. Old order was: always, relation, relationModifier,
1513 structure, index, position, truncation. Note that the the latter ones
1514 override former ones for identical attributes.. The new scheme means that
1515 it is possible to override any existing attribute with a relationModifier.
1516 And also that it is possible to override everything for the index rule
1517 (except the ones listed in relationModifier). No order is perfect but this
1518 one, we believe, covers more real cases.. The "always" should have been
1519 called "default", since the attributes there can be overridden with all
1522 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1523 compilation phase, but also for yaz-config --cflags output. This allows
1524 us to have public headers with Libxml2 stuff in them . It should also,
1525 eventually, make Libxml2 checks redundant in packages using YAZ, such
1528 --- 2.1.22 2006/06/15
1530 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1531 stored in uri, message and details.. Previously diagnostics were stored
1532 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1533 compatibility.. but he's probably the only one affected, so.
1535 Added support for CCL, compiled on the client side, in ZOOM-C. This
1536 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1537 input; the resulting query objects can be used for for searching with
1538 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1540 YAZ' configure searches for OpenSSL by default.
1542 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1543 SL_CTX_use_certificate_file. See
1544 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1545 for more info. Thanks to Ko van der Sloot.
1547 --- 2.1.20 2006/06/02
1549 Bug #600: SRU GET, POST support for yaz-client. Introduced
1550 command 'sru' which selects method SOAP/GET/POST.
1552 Allow missingValueAction to be specified for the sortspec string -
1553 function yaz_sort_spec. By default, the missing value action is null.
1554 Use ! to specify "abort". Use = followed by stringvalue to specify default
1557 Ensured that Present-handler (if defined) is called in GFS before any call to
1558 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1559 searchRetrieve requests.
1561 Documentation for YAZ is now based on the Docbook XML/XSLT using
1562 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1563 is no longer depending on jade/openjade or docbook-to-man scripts.
1564 PDF is no longer part of the distribution - but can optionally be
1565 made using DSSSL/jadetex or FOP.
1567 Added retrieval handling support in Generic Frontend Server to support
1568 conversion between MARC/XML as well as XSLTtransforms. See
1569 etc/yazgfs.xml for an example.
1571 Added Authentication support to Generic Frontend Server in SRU
1572 mode. Authentication using HTTP Basic is supported, as is the use
1573 of 'x-username' and 'x-password' parameters in the request itself.
1575 Added support for a new character set MARC8s identical to MARC8 except
1576 that it converts combined characters to single Unicode characters in the
1577 Latin-1 range (when possible).
1579 --- 2.1.18 2006/04/24
1581 ASN.1 compiler 0.4: generates brief Doxygen file header for
1582 generated .h/.c files.
1584 Utility yaz_iconv now supports conversion to MARC-8.
1586 New facilities for the MARC module. The reading - and writing of
1587 content are separate methods for the yaz_marc_t handle. The following
1588 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1589 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1590 format). Write functions have prefix yaz_marc_write_.. The existing
1591 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1592 available. Removed support for OAI-MARC and simplexml (not the
1593 simplexml from PHP5).
1595 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1596 to be returned for this connection.
1598 --- 2.1.16 2006/03/31
1600 Allow multiple languages and charsets to be specified with
1601 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1602 negcharset iso-8859-1,utf-8
1604 Translation of proximity nodes from CQL into PQF now works.
1606 Moved to automake 1.8, 1.9.
1608 Added function yaz_log_set_handler which allows a log handler to be
1609 installed. This handler will be called for all log messages. Output
1610 to file is also produced; but that can be disabled by passing NULL
1611 fname to yaz_log_init_file.
1613 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1615 For SRW (including GFS), accept application/soap+xml as content-type
1618 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1619 produces NO stylesheet reference even if a default stylesheet is specified
1622 --- 2.1.14 2006/03/14
1624 Updated Windows package to include yazd.dll + yazd.lib for the
1625 Development component.
1627 If the environment variable YAZ_LOG is set, then it is used as a
1628 string indicating the default level of logging to use if not
1629 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1630 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1631 used as before. So, for example, to omit warnings from YAZ logging,
1632 export YAZ_LOG=-warn
1634 cql_transform() now map structure and other attributes before indexes,
1635 so that index-specific structures and other attributes can override
1636 defaults. So now a combination of mapping specifications such as:
1638 index.dc.date = 1=date-modified 4=5
1639 does the right thing.
1641 cql_transform() now also respects the "always" mapping specification,
1642 which establishes an initial set of attributes to be used for all
1643 terms except where overridden by more specific attributes associated
1644 with the index, relation or modifier.
1646 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1647 which mode to use; one of "post", "get" or "soap" (SRW, default).
1649 Fixes for yaz_iconv routines: changed trie-based character set conversions
1650 to use only non-negative values for bit fields due to Sun's C compiler not
1651 supporting negative values.
1653 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1654 sequences where not read correctly. Fix by Rustam Usmanov.
1656 Updated win/makefile to use options, settings which makes things
1657 compile with VS C 2005.
1659 --- 2.1.12 2006/02/01
1661 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1663 In ZOOM socket code, use select instead of poll on MacOSX.
1665 ZOOM-C now support client-side compilation of CQL into RPN that is
1666 sent to the server, enabling CQL to be used against all Z39.50
1667 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1668 ZOOM_query object, and submit it using ZOOM_connection_search().
1669 The CQL-to-RPN translation uses a configuration file, the name of
1670 which must be specified in the Connection's "cqlfile" option.
1672 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1673 function, which takes as its start-term parameter a ZOOM_query object
1674 (which may have had either CQL or RPN set into it).
1677 --- 2.1.10 2005/11/29
1679 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1680 GFS to support this as well. Backend handler, bend_srw_update, does the
1681 update work. Code contributed by Ko van der Sloot.
1683 Allow retrieval of Search Result-1 information in ZOOM by the use of
1684 options that are attached to a result set. ZOOM documentation updated
1687 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1688 UTF-8 conversion. Patch by Raj Patel.
1690 Added option -m to GFS to control formatting of timestamps in log file.
1692 Added 'exit' as synonym for 'quit' in yaz-client
1694 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1695 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1696 for the new members. Patch by Ko van der Sloot.
1698 Added support for SRU POST. It is supported for content-type
1699 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1701 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1702 Instead make the library libyaz.la multi-threaded. Threading as a whole
1703 can still be disabled by configure option --disable-threads. Previosly,
1704 with older GLIBCs there were problems with MT libs under Apache. This
1705 has now been fixed a long time ago.
1707 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1710 CQL module modified to be case insensitive for relations/indexes/operations.
1712 Fixed bug in CQL transform code: incorrect value relationModifieder
1715 Added 'show all' command for yaz-client which retrieves all results
1718 Added new yaz-client, xmles, which takes a (private) OID and
1719 a document to be sent as an extended service request.
1721 Describe new yaz-client commands wait_response and set_auto_wait.
1723 Increase TCP/IP listener backlog from 3 (which I am guessing was
1724 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1725 that the socket will queue as many incoming connections as it's able
1726 to handle ongoing connections. In other words, it will never now
1727 refuse a connection that it would be able to handle merely because
1728 it's not got around to accepting() enough of the pending connections
1729 yet. This is the behaviour anyway under Linux, where the listen()
1730 argument is ignored; but not under BSD and on systems such as
1731 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1732 YAZ-based servers should now be uniform across operating systems in
1735 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1736 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1737 This allows yaz-marcdump to read large MARC batches (>2 GB).
1739 Modified all YAZ source files - except the source which is auto-generated
1740 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1743 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1744 corresponding to the existing *_setl() function. These allow option
1745 values containing arbitrary valuues.
1747 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1748 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1749 except that it returns an indicator of whether or not the sort
1750 criterion was accepted (0 for OK, -1 for invalid).
1752 --- 2.1.8 2005/06/07
1754 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1755 MARC output rather than returning "new" buffer.
1757 yaz-client warns about unknown init options.
1759 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1761 --- 2.1.6 2005/05/24
1763 Added support for SRW sort in Generic Frontend Server. Patch
1764 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1765 sortKeys - or NULL if none is provided.
1767 Fixed bug #307: It was impossible to specify indefinite/no timeout
1768 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1771 Added support for multiple languages and charsets to be specified in
1772 ZOOM. Each charset/language is separated by a blank. If negotiation is
1773 in effect in init-response, Option
1774 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1775 Code based on patch by Vasiliy Osadchuk.
1777 Fixed bug #306: infinite recursion that occurred when calling
1778 yaz_log_level_init as the first call (before other log level or
1781 Fixed bug in scan handling in front end server: if preferred-Position-In-
1782 Response was non-present, a NULL pointer referece was performed.
1784 --- 2.1.4 2005/04/26
1786 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1787 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1788 now defined for all those error codes. So instead of putting 109 in
1789 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1790 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1792 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1795 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1797 Program yaz-client now exits and produces an error message if multiple
1798 Z39.50 servers are specified on the command line (none or one allowed
1801 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1804 --- 2.1.2 2005/03/16
1806 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1808 Fixed bug #272: Preserve spacing for CCL terms.
1810 --- 2.1.0 2005/03/14
1812 Added support for virtual hosts and multiple backend servers for
1813 the YAZ frontend server. The configution is XML based and
1814 support specificition of CQL to RPN mappings and explain information.
1815 See section "Virtual Hosts" in the YAZ manual.
1817 Extended OPAC display utility. OPAC display utility renders
1818 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1819 to supplement yaz_marc_decode_wrbuf.
1821 Fixed a bug in MARC decoder that could caused it to crash for some
1822 invalid MARC records. More diagnostics and warnings where added in
1823 XML output (warnings, etc are stored in comments).
1825 --- 2.0.34 2005/02/08
1827 Fixes for UNIX domain sockets. Bug #261.
1829 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1831 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1832 Added yaz_marc_subfield_str which defines subfield lead string which is
1833 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1834 yaz_marc_endline_str which defines end of fields string used in
1835 YAZ_MARC_LINE format. Default string is newline.
1837 Experimental support for MarcXChange. This format can be produced
1838 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1839 http://www.bs.dk/standards/MarcXchange.xsd
1841 Added yaz-client commands scansize that sets maximum number of
1842 entries to be returned by scan.
1844 --- 2.0.32 2005/01/11
1846 Added support for SRW scan in yaz-client and Generic Frontend Server.
1848 * Added whereInList member to SRW Scan Term.
1850 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1852 Fixed NMEM system to return aligned blocks on the smallest boundaries
1853 that are suitably aligned for all possible types on the particular
1854 architecture YAZ is being built for.
1856 --- 2.0.30 2005/01/04
1858 Fixed numerious warnings that was issued with newer versions of GCC.
1860 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1861 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1864 Make YAZ Generic Frontend Server slightly faster.
1866 Enhance (and reduce) logging for Generic Frontend Server.
1868 Revert YAZ log system so that it flushes every write operation
1869 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1871 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1872 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1873 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1874 will effectively disable old definitions.
1876 --- 2.0.28 2004/11/09
1878 Added yaz_log_time_format which specifies log format using
1881 Added yaz_log_module_level which returns mask for a module. Value
1882 is non-zero mask a if module is enabled; zero if disabled.
1884 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1885 in include/yaz/cql.h.
1887 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1889 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1891 Fixed bug #172: RPM builds does not enable SSL.
1893 Doxyfile.in part of dist. Doxyfile generated by configure.
1895 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1896 are given and the corresponding component does not exist.
1898 Extend CCL documentation in YAZ reference. Describe r=r.
1900 --- 2.0.26 2004/10/01
1902 Fixed MARC->MARCXML conversion to properly deal with
1903 fields, subfields, indicators having non-ASCII characters.
1905 Fixed MARC->MARCXML conversion so that ASCII control characters
1906 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1909 Added YAZ GFS support for conversion from Z39.50 surrogate
1910 diagnostics to SRW surrogate diagnostics.
1912 Bug fix: YAZ GFS did not return schema in explainResponse.
1914 --- 2.0.25 2004/09/30
1916 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1917 now converts recordSchema to elementSetName as well as schema URI.
1919 Fixed bug in COMSTACK that prevented HTTP request packages from being
1922 --- 2.0.24 2004/09/29
1924 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1925 does not require white-space before and after the dash in a range, e.g.
1926 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1929 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1930 due to new GCC removing "redundant" code.
1932 Added yaz-client commands scanpos and scanstep that sets preferred
1933 position and step-size for scan.
1935 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1937 Added CCL utility ccl_qual_buf which parses one or more CCL
1938 spec lines in a buffer.
1940 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1941 of name and value - ignoring empty lines and comments.
1943 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1945 Added odr_get_element_path which returns current element path for an
1946 ODR handle. This utility is useful in error handling or user-defined
1949 Added ODR_PRINT utility odr_set_stream which is is a more generic
1950 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1951 to a write function and pointer to close function. The close function - if
1952 non-NULL - will be called during odr_destroy.
1954 Fixed bug in CCL parser where truncation char was not removed from
1955 right side when truncation=both was in effect.
1957 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1960 --- 2.0.23 2004/08/11
1962 Fix buffer overrun in CQL parser when dealing with proximity (%).
1964 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1965 to UTF-8/UCS conversion is now only based on codetables.xml.
1967 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1969 --- 2.0.22 2004/08/06
1971 Add support for more "commit changes" in ZOOM (uses Extended Services).
1973 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1976 Yet another small fix for configure of SSL.
1978 --- 2.0.21 2004/05/14
1980 Fix SSL libs for configure when --with-openssl=DIR is given.
1982 --- 2.0.20 2004/05/10
1984 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1986 SSL comstack now uses yaz.pem certificate file on server side
1987 by default. Certificate filename can be configured by calling
1988 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1990 Fix bug regarding multiple calls to ZOOM_connection_connect.
1992 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1994 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1995 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1997 ZOOM now allows inspection of X509 peer certificate for verification.
1998 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2000 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2001 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2002 as "modular" but it simplifies things.
2004 Added cs_get_peer_certificate to that returns peer X509 PEM.
2006 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2007 NULL if SSL is unavailable.
2009 Documentation about MARC decoding tools.
2011 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2013 --- 2.0.19 2004/03/30
2015 Rename CHANGELOG to NEWS to follow GNU style packing.
2017 Fix bug with missing initialization of member in init_diagnostics.
2018 This bug affects threaded version of GFS server.
2020 --- 2.0.18 2004/03/20
2022 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2025 Ensure zlib.dll is packed with Windows install.
2027 --- 2.0.17 2004/03/17
2029 Fix encoding of xsd:string to use text instead of CDATA.
2031 Fix endless loop in CQL parser with unbalanced ".
2033 Use a more compact way to store MARC-8 conversion tables.
2035 --- 2.0.16 2004/03/16 Debian only
2037 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2040 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2045 --- 2.0.15 2004/03/01
2047 Another fix for decoding of XML packed records.
2049 --- 2.0.14 2004/02/25
2051 Fixes for Chunked encoding. White space not ignored after length spec.
2053 Update NS and use default NS for SRW diagnostic elements.
2055 --- 2.0.13 2004/02/23
2057 Implement ZOOM_resultset_cache_reset which resets record cache.
2059 Implement ZOOM_resultset_sort which sorts a result set.
2061 Implement chunked HTTP transfer.
2063 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2065 --- 2.0.12 2004/02/16
2067 Added member 'schema' to bend_explain_rr structure so that backend
2068 can specify explain record identifier. Defaults to Zeerex 2.0.
2070 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2072 --- 2.0.11 2004/02/16
2074 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2077 Added init command for yaz-client which sends "extra" init request.
2079 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2080 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2082 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2084 Make ZOOM error code for "invalid query".
2086 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2088 --- 2.0.10 2004/02/05
2090 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2093 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2095 Added option -p <file> to make Generic Frontend Server to write PID file.
2097 Added option -D to put Generic Frontend Server in background on its own.
2099 Make ZOOM C recognize option "password". If unset, "pass" is used
2100 (for backwards compatibility).
2102 Fixed a bug in Generic Frontend Server that could make it crash if a
2103 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2106 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2107 Must be issued before open, in order to be in effect.
2109 --- 2.0.9-6 2004/01/12 Debian/Windows
2111 Make the SRU server more picky WRT unknown params, etc.
2113 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2115 New YAZ client command, options, that sets Z39.50 options.
2117 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2118 options from a string of tokens (one token for each option bit).
2120 Update SRW diagnostic code messages.
2122 --- 2.0.9-5 2004/01/07 Debian/Windows
2124 Handle user defined stylesheet for SRW/SRU.
2126 --- 2.0.9-4 2004/01/06 Debian/Windows
2128 Fix bug in decoding of Content-Length.
2130 --- 2.0.9-3 2004/01/06 Debian/Windows
2132 Fix a bug with decoding of XML packed records.
2134 --- 2.0.9-2 2004/01/05 Debian only
2136 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2138 Fix bug in SRW/SRU diagnostics decoding.
2140 --- 2.0.9 2004/01/05
2142 Fixed bug in Generic Frontend Server which could drop records exceeding
2143 preferred message size. Reported and fixed by Irina Dijour.
2145 Fixed calculation of package size for structured records in Generic
2146 Frontend Server. Reported and fixed by Irina Dijour.
2148 Fixed namespace for SRW/SRU diagnostics.
2150 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2152 --- 2.0.8 2003/12/22
2154 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2155 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2158 CQL changes to reflect recent changes to the specification:
2159 * Documentation talks about context sets instead of index sets.
2160 * Documentation talks about indexes instead of qualifiers.
2161 * The CQL-to-PQF transformer's configuration file now uses
2162 "index.set.name = <attributes>" instead of the old form
2163 "qualifier.set.name = <attributes>". (Both forms are still
2164 understood but the latter is deprecated.)
2165 * CQL terms with no explicit index specified are now interpreted as
2166 cql.serverChoice instead of srw.serverChoice (which of course
2167 behaves exactly the same.)
2169 --- 2.0.7 2003/12/16
2171 MARC conversion can now generate ISO2709 output in another
2172 character set. yaz-marcdump uses this facility if you invoke it
2175 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2176 functions from there can be used from C++.
2178 --- 2.0.6 2003/12/04
2180 Frontend server now transfers memory from decoded packages to stream
2183 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2184 references to show up.
2186 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2187 the ZOOM Abstract API. The older names for the same options are still
2188 also supported for the benefit of old applications.
2190 ZOOM-C supports "implementationId" and "implementationVersion" options
2191 to go along with "implementationName". These allow the user code to
2192 specify identification strings to be sent to servers.
2193 Add OID for the new ExtLite attribute set.
2195 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2196 as requested/supplid by Ere Maijala <ere@atp.fi>
2198 For generic frontend server, reverse the order of
2199 "toolkit-supplied / application-supplied" strings sent as implementationId,
2200 Name and Version. Also, remove the spaces around the slash. This brings
2201 the GFS in line with the behaviour of ZOOM-C on the client side.
2203 Add function ZOOM_scanset_display_term.
2205 yaz-client shows scan displayTerm if present.
2207 Utility yaz-iconv is now installed by default along with the man page
2210 Extend configure check for OpenSSL to use pkg-config where available (such
2213 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2214 server to specify uid/gid/mask for socket using the format
2215 unix:[user=uid,][group=gid,][umask=mask,]file=path
2216 If file= is omitted the existing format is assumed, e.g.
2218 in which case the mask is 0666 (rw for everybody).
2220 Major restructure of YAZ source. All source in libyaz is in src directory.
2221 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2222 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2224 Added man page for utility yaz-marcdump (used to be called marcdump).
2225 yaz-marcdump is installed by 'make install'.
2227 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2228 of incoming package failed.
2230 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2232 Change prototype of odr_perror: add const to message string.
2234 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2236 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2237 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2238 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2239 DNS lookup. There should not be any compatibility problems with this
2240 assuming that blocking=1 or 0 is used.
2242 Fix bad reference in UNIX comstack in function cs_addrstr.
2244 Fix for compilation on AIX.
2246 The generic front-end server (server/seshigh.c) now supports returning
2247 Init diagnostics to the client in User-information-field, in
2248 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2251 --- 2.0.4 2003/09/04
2253 Allow any CQL relation (not just all,any,exact,scr).
2255 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2256 that features the same UI.
2258 Implemented command update0 in YAZ client which is equivalent to
2259 update but uses old of Ext Update ASN.1.
2261 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2262 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2263 Previously no OID was used for this info.
2265 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2266 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2267 returns 'malformed search term' otherwise.
2269 SortResponse member resultCount now set to NULL in sort handler of
2272 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2275 Add three new utility functions for translating OIDs between various
2276 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2277 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2278 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2279 char *oid_to_dotstring(const int *oid, char *oidbuf);
2280 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2282 Reverted modifications for ES Update definition for z_IU0Update
2283 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2284 is back to YAZ 2.0.2.
2286 String value attributes for CCL parser.
2288 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2289 which their FirstSearch server returns in Init responses, sometimes
2290 carrying useful diagnostic information when Init fails. This has the
2291 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2292 "z39.50/oclcui.asn", where its definition is somewhat different from
2293 what OCLC document on their web-site, as required to interoperate with
2296 Support for anonymous authentication in yaz-client. Use the command
2299 * Fix the OID of the Index Data-local "admin" Extended Service from
2300 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2301 the 1000, which indicates a locally-defined OID, was a mistake.
2303 --- 2.0.3 2003/06/20
2305 Fix CCL directive @case handling so that it affects string match for
2306 both CCL keywords and qualifiers.
2308 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2309 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2310 Decoder has been updated with ASN.1 changes as listed in
2311 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2312 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2313 z_IUUpdate, remains unchanged.
2315 ZOOM_record_get may now return a record in a specific character set.
2316 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2317 "from" is the character set of record as returned by target. "to" is
2318 the character set to be returned. If omitted, "to" is UTF-8.
2320 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2322 New ODR utility, odr_getelement, which returns name of element for
2323 which encoding/decoding failed.
2325 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2326 in cases where a required element was omitted.
2328 Bug fix: some MARC8 sequences were not converted.
2330 New ZOOM option "step" which specifies number of records to be
2331 retrieved in one chunk. Used in conjunction with "start" and "count".
2333 SRW support for yaz-client. Use scheme http: to use it, e.g.
2336 yaz-client no longer does (un)intelligent character set conversions
2337 by default. Can be enabled with charset and marc_charset commands.
2339 xmalloc trace fix for 64-bit systems such as DEC alpha.
2341 Solaris 2.6 compile fix.
2343 New function, cql_strerror() translates SRW error codes, as returned
2344 by cql_transform_error(), into human-readable English strings. Used
2345 in yaz-client diagnostics when appropriate.
2347 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2348 converts it into a type-1 query which is sent to the server. This
2349 makes CQL available for use with all Z-servers, as opposed to the tiny
2350 minority that can handle CQL queries themselves.
2352 --- 2.0.2 2003/04/28
2354 New Debian package layout similar to the Redhat Package layout.
2356 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2357 and search result respectively.
2359 --- 2.0.1 2003/04/25
2361 Redhat package is now several packages: libyaz (runtime libraries),
2362 libyaz-devel (development and documentation, and yaz (utility programs).
2363 Package spec file by Morten Bogeskov.
2365 New member 'schema' in struct bend_fetch_rr which the name of requested
2366 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2367 handler MAY set this to reflect the schema of the returned record.
2369 New member 'display_term' in struct scan_entry. GFS now sets member entries
2370 and allocates scan entries to be filled by user scan handler. In previous
2371 version, entries member was allocated by the scan handler. That still works,
2372 but the GFS will ignore member display_term - assuming it was NOT set by
2373 the handler. The fact that the GFS now allocates the entries both allows
2374 for new members and makes a scan handler easier to write.
2376 Fix CQL lex buffer overflow.
2378 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2379 SRU default recordPacking is string.
2381 SRU protocol support for frontend server.
2383 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2385 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2387 Added scan for the ZOOM shell (zoomsh).
2391 * String Identifers for Schemas (Amendment 5).
2392 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2393 Old definition for schema
2394 Odr_oid *schema; /* OPT */
2399 Z_InternationalString *uri;
2400 #define Z_Schema_oid 1
2401 #define Z_Schema_uri 2
2404 * resultCount parameter to Sort Response (Amendment 1).
2405 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2407 Support for SRW 1.0 over HTTP. This is an optional feature and
2408 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2411 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2412 on the same port. SRW SearchRetrieveRequests are mapped
2413 to bend_init,bend_search,bend_fetch,bend_close.
2415 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2417 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2418 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2420 ZOOM connections are SRW based if schem http is used for hostname
2421 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2422 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2424 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2425 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2426 distance=n, order=true/false, relation=le, prox unit=word. If
2427 n is omitted, distance 1 is used.
2429 Fixed problem with C compiler include path in wrong order.
2431 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2432 on Solaris. Patch from Ko van der Sloot.
2434 New MARC decode API. All new functions operate on a yaz_marc_t
2435 handle. The most important new functions are: yaz_marc_create,
2436 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2437 decode and destroy respectively. Decoder can produce formats
2438 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2439 include/yaz/marcdisp.h.
2441 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2442 to UTF-8, UCS-32, wchar_t or Latin-1.
2444 * Prototypes for yaz_iconv_-functions moved to separate header
2445 include/yaz/yaz-iconv.h.
2447 Make a few private functions 'static' in unix.c. This prevents
2448 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2450 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2451 are set when Init Response is received.
2453 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2454 but returns diagnostic set as well.
2456 New function yaz_strerror which is a portable wrapper for
2457 strerror/strerror_r/GetLastMessage.
2459 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2460 is returned for MARC. If type is "oai", then OAI MARC is returned.
2462 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2465 --- 1.9.2 2002/11/26
2467 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2469 Fix bad race conditions on SIGTERM and terminate gracefully in
2472 Move retrieval (data1) module to Zebra since nobody seems to be
2475 Add GRS-1 render for ZOOM using same format as yaz-client.
2477 --- 1.9.1 2002/10/05
2479 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2481 Fix broken ESpec handling in data1 module.
2483 SGML reader parses comments and makes them part of the data1 tree.
2485 Added several type casts so that YAZ compiles as C++ code.
2487 ZOOM didn't handle PDU encoding failures properly.
2489 Added more Bib-1 diagnostics (approved extensions).
2491 GNU configure: better check for iconv.
2493 More portable use of accept, getpeername. Check for socklen_t. Use
2494 int/size_t if socklen_t is not defined.
2498 PQF parser rejects bad queries - including those with extra
2499 characters in them. PQF parser used to silently ignore that.
2500 Cleaner API for PQF added, which allows you to get detailed
2501 error information for bad queries (see yaz/pquery.h).
2503 Fixed bug in ZOOM_record_get for type "database".
2505 Implemented mini iconv library supporting conversions between
2506 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2508 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2510 --- 1.8.9 2002/08/20
2512 Fixed ZOOM C record cache so that preferredRecordSyntax and
2513 elementSetName is used to check for already fetched records.
2515 --- 1.8.8 2002/08/02
2517 Added three members in bend_initrequest structure to facilitate
2518 character set negotiation.
2520 Fixed a bug in frontend server that could cause indefinite
2521 loops under rare conditions.
2523 Revised character set utilities (charneg.h) so that encoding
2524 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2526 For PQF, directive @term <type> sets term type for Scan/Search.
2527 Here <type> is general, string, numeric, null. The term type
2528 is inherited - just like @attr.
2530 New call odr_set_charset that sets character set conversion for
2531 international-strings on a ODR stream. Prototype is:
2532 int odr_set_charset(ODR o, const char *to, const char *from);
2533 The InternationalString is still represented as C string in YAZ
2534 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2535 won't). On the protocol level, you can use any encoding.
2537 Support for UNIX sockets in ZOOM.
2539 Solaris recv sometimes returns errno == ENOENT. It is treated as
2540 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2542 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2543 both client and server. Code by Morten Bogeskov.
2545 --- 1.8.7 2002/05/22
2547 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2548 that they can be used directly from Visual Basic. You must recompile
2549 your windows APP if you're using ZOOM.
2551 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2552 Commands "lang" and "charset" sets language and character set respectively.
2553 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2554 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2556 Attributes from multiple CCL fields may be OR'ed rather than merged
2557 using directive "@field or". Fields are still merged by default -
2558 equivalent to "@field merge".
2560 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2563 Fixed bug in zget for parameter ExtendedServicesResponse.
2567 --- 1.8.6 2002/03/25
2569 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2571 Client displays USR.1:SearchResult-1 (hits per term).
2573 Additional Search Info for search in Generic Frontend Server.
2575 Fixed CCL parsing of "field=s".
2577 WIN32 installer - using the excellent NSIS software from nullsoft.
2579 Fixed CCL parsing of "field = - <number>".
2581 Added function yaz_marc_decode that decodes MARC for line mode
2582 display or XML (similar to that used by JZKit).
2584 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2585 Z39.50. But ISO/ILL was, however.
2587 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2588 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2591 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2593 --- 1.8.5 2002/02/03
2595 New YAZ client features: Command completion and new commands:
2596 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2597 Code provided by Jacob Poulsen.
2599 New call oid_trav, that visits all registered OIDs via callback.
2601 Function ZOOM_record_get now returns const char pointer rather than
2602 void pointer. It saves a lot of type casts.
2604 For YAZ client, command "auth" now allows you to set authentication
2605 in IdPass style. It is enabled when three tokens are given - order
2606 is user, group and password.
2608 Fix memory leaks in MARC record handling for ZOOM.
2610 New option for YAZ client, -k <kilobytes> that sets
2611 maximum record size. Similar to -k option for generic frontend
2612 server and yaz-ztest.
2614 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2616 Prefix query parser reports "fail" when bad attribute set is given.
2618 Fix in MARC decoder. Proximity logging. Fix for attribute set
2619 in scan handler for server. Patches by Shigeru Ishida.
2621 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2624 Configure option --with-openssl=<dir> now works when a directory is
2625 specified. Patch provided by Morten Bogeskov.
2627 New option for YAZ client, -u <auth>, that sets authentication.
2629 ZOOM fix: error information was sometimes "missing", since error
2630 was cleared/reset too when it shouldn't.
2632 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2634 --- 1.8.4 2002/01/04
2636 Scan for ZOOM API. New object ZOOM_scanset. New functions
2637 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2638 ZOOM_scanset_destroy.
2640 New ZOOM function, ZOOM_connection_last_event, that returns type
2641 of last event (such as "receive data", "send data", "apdu received",
2644 New ZOOM option, schema, that specifies schema for retrieval.
2646 New CCL feature. Qualifiers can be aliases for one or more
2647 other qualifiers (if more than one is given, OR is used).
2649 ZOOM uses named result sets if target supports it.
2651 Two new YAZ client commands: . (dot, which sources a script of YAZ
2652 client commands), and ! (to execute shell command.). Implemented
2655 Working on Debian packages.
2657 --- 1.8.3 2001/11/19
2659 YAZ client enables named result sets only if target supports it.
2661 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2663 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2664 with key="host" to get same result.
2666 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2667 Function Z3950_resultset_record(s) returns references to records
2668 "owned" by resultset. To become owner use Z3950_record_clone.
2670 Function z_ext_record handles Extended Services. Thanks to
2673 --- 1.8.2 2001/11/12
2675 CCL Parser fix: ignore token comma when dealing with and-lists.
2677 Documentation updates for COMSTACK.
2679 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2680 Changed prototype Z3950_records. For some functions, int parameters
2681 were changed to size_t.
2683 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2686 New MARC decode/display function, marc_display_exl, which properly rejects
2687 non-ISO2709 records. YAZ client uses it.
2689 --- 1.8.1 2001/10/29
2691 Fix bug: local attribute set wasn't set correctly in PQF strings.
2695 * Old Z39.50 codecs no longer supported.
2697 Added ZOOM C binding. See http://zoom.z3950.org/
2699 Renamed states for COMSTACKs to avoid confusion with events.
2701 Implemented cs_look and proper cs_rcvconnect.
2703 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2705 Configure detects POSIX threads on OpenBSD.
2707 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2708 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2710 When error is returned from present handler, non-surrogate diagnostic
2711 is returned in present response (and fetch handler is no longer called).
2713 * Minor adjustments to pquery parser (PQF). Token characters may be
2714 escaped by using backslash (C-style).
2716 PQF parser allows string attribute values to be specified. For @attr,
2717 non-numeric characters after the equal-sign are treated as strings
2718 (e.g. @attr 9=title).
2720 CCL trunction character may be defined (@truncation in file)
2722 * function zget_ExtendedServicesRequest sets waitAction to
2723 waitIfPossible (was wait).
2725 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2728 CCL operator names may be set in field definition files (CCL_bibset).
2729 See ccl/bib1 for an example.
2731 Fixes in ASN.1 compiler for C++ compatibility.
2733 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2734 and "op_or" to avoid conflict with C++.
2736 Fixed problem with GNU readline detection on Redhat 7.0.
2738 Added step-size for Scan backend handler.
2740 Fixed bug that made the frontend server crash when no attribute
2741 set was specified for scan.
2743 Front-end server automatically switches to original working directory
2744 when installed as an NT service. Previously -w had to be specified to
2747 Added extended attributes for retrieval module (data1), so that data1
2748 records carry d1_readXML/SGML attributes. d1_read also supports
2749 null-data rules ( <tag/>)
2751 On UNIX when POSIX threads are available, a separate library libyazthread
2752 is created. Programmers should link with that library and the yaz library
2753 when using threads. The reason for the split was that some applications
2754 on Linux, such as Apache, doesn't work well when using shared objects that
2757 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2758 (or any frontend server) in SSL mode by specifying ssl: followed by
2759 address. Only tested on UNIX.
2761 Added feature for CCL module. Virtual structure s=al or s=ol generates
2762 and-list and or-list respectively instead of phrase search.
2766 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2767 log_mask_str. This was done to avoid name conflicts with other libraries
2768 (such as other PHP extensions).
2770 Added raw OID member for preferred record syntax (request_format_raw)
2771 and returned record syntax (output_format_raw) for backend fetch method.
2773 Config file yaz-config now accepts options so that it returns specific
2774 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2776 Shared library support for UNIX using GNU libtool.
2778 * Modified backend interface. Request/Response struct's replaced by
2779 one read/write C struct. For example bend_fetchrequest and
2780 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2781 Every handler - even search has to be registered in bend_init
2782 handler. This means that the YAZ library no longer refers to
2783 external functions and it makes it possible to make the whole
2784 thing a single DLL/SO.
2786 Added Segment handler for backend server.
2788 Added Zmbol/Zebra administrative functions to YAZ client.
2790 Threaded frontend server on UNIX (when POSIX Threads are available).
2791 Starting the server with option -T enables multi-threading.
2795 Added configure option --enable-comp/disable-comp to control use
2796 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2797 located in sub directory asn.
2799 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2800 in ${exec_prefix}/bin along with the other programs yaz-client and
2803 GNU automake used to maintain makefiles.
2805 Added several OID's.
2807 Changed retrieval module so that we can load records with no abstract
2808 syntax defined. Tagpaths in these records are fully composed of string
2811 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2815 On UNIX, the generated makefile now supports a proper 'make install'.
2816 The prefix can be set via GNU configure to set the install location
2817 (default is /usr/local).
2819 * YAZ programs client and ztest were renamed to yaz-client and
2820 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2821 locations, such as /usr/bin,/usr/local/bin,etc.
2823 * YAZ Header files were moved from include to include/yaz. YAZ Header
2824 files are referred to as include <yaz/log.h> rather than <log.h>.
2825 The YAZ include path (-I ..) is therefore the same as before. Programmers
2826 should update their #include statements or use -Ipath/include/yaz
2827 instead. The main motivation for doing this change is that YAZ header files
2828 can be installed in "standard" locations /usr/include,/usr/local/include
2829 without introducing conflicts, since ALL YAZ header files are stored
2830 in subdirectory yaz (under /usr/include for example).
2832 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2833 rather than project/workspace files. We switched because project files
2834 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2837 Changed name of logging function, logf, to yaz_log, to prevent name
2838 clash with some math-log functions. The YAZ header log.h defines logf
2839 to yaz_log (#define) so there should be no incompatibilities by this
2842 Added bend_start/bend_stop handlers for server. These handler are
2843 called on start/stop of server. For windows they are called whenever
2844 a service is started/stopped.
2846 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2847 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2848 in util/yc.tcl. The auto-generated C code structures are, in a few
2849 cases, incompatible with the old decoders. There are differences in the
2850 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2851 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2852 The preprocessor variable ASN_COMPILED is defined when the compiled
2853 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2854 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2855 wish to use the old encoders/decoders you can specify --disable-yc
2858 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2859 version so that it supports both new - and old version of DB Update
2861 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2862 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2863 change. The name parameter can be set to 0 in which no name is specified
2864 for the construction. The macros odr_implicit and odr_explicit sets name
2865 parameter to zero for the construction involved. New macros
2866 odr_implicit_tag and odr_explicit_tag are similar to the others,
2867 except that a name parameter is added. For programmers' that don't use
2868 ODR they probably only need to change the call to z_APDU and z_External.
2870 Added access control facility by interfacing the TCP wrapper library.
2871 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2872 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2873 name of the daemon and enables the access control as specified in
2874 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2876 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2877 den Dool <H.M.vdnDool@kub.nl>.
2879 Added reference ID parameter to most functions in server API - refer
2880 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2882 Changed name of ccl library to libccl.a (was ccl.a).
2884 Fixed bug in decoder for Explain (Category TargetInfo).
2886 Added support for GNU readline in client. Thanks to Jacob Poulsen
2887 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2889 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2890 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2891 IMPLEMENTATION! This change was made to the development version before
2892 the ZIG decided to retract the amendment. If any users MUST be
2893 compatible with the original Update definition, PLEASE CONTACT US, and
2894 we will include a separate definition corresponding to the old Update
2895 ES. Note that because of the change to the ASN.1 of the
2896 TaskPackageRecordStructure we cannot define a single structure that
2897 will support both versions.
2899 * Added const modifier to buffer parameter for some ODR/BER encoding
2900 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2901 completeWAIS, odr_dumpBER.
2903 Fixed bug in client.c which caused a crash when a scanResponse didn't
2904 contain positionOfTerm.
2906 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2907 * will cause an error in a client if a non-YAZ target sends both a
2908 * list of Scan entries and non-surrogate diagnostics.
2910 Retrieval module enhancements. Tag sets may be typed in the reference
2911 to it. From the .abs-file the "tagset" directive takes a third optional
2912 integer type for the tag set referenced. From a .tag-file the "include"
2913 directive takes a third optional type as well. The old "type" directive
2914 in the tag set itself is still recognized but acts as the default type
2917 Backend interface change. Individual Scan terms returned from bend_scan
2918 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2919 in include/backend.h.
2921 Retrieval module enhancements. Multiple tag sets and attribute sets may
2922 be specified in abstract syntax specs. Revised the error/warning for
2923 logging messages reported by the retrieval module when reading the
2926 Object Identifier system (oid_..) changed. The API is backwards
2927 compatible but the oid-routines now allocates new OID's when needed.
2928 Raw OID's may be specified in oid_getvalbyname.
2930 YAZ now uses GNU configure to generate Makefile(s).
2932 * Minor changes in some of the member names of DeleteResultSetRequest and
2933 DeleteResultSetResponse. See include/proto.h.
2935 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2936 and added member 'languages' in TargetInfo (which was missing).
2938 Changed the way attribute sets are handled in the retrieval
2939 module. These are now cached, just like the abstract syntaxes
2942 Changed YAZ so that it links with compiled ASN.1.
2944 Added Explain-schema definitions and mapping routines. The following
2945 Explain categories have been implemented: AttributeDetails,
2946 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2948 Fixed minor bug in Windows version of Server Library.
2950 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2952 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2954 Added EXTERNAL: UNIverse Resource Report (non-standard).
2956 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2957 ENUMERATED and SET OF.
2959 * Added 'const' to some of the char pointer arguments for the
2960 functions, data1_read_node, data1_getelementbytagname,
2961 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2964 Fixed bug in data1_insert_taggeddata - the last_child member of
2965 parent wasn't initialised.
2967 * Changed data1_read_record and data1_read_node so that the supplied
2968 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2969 doesn't refer to any parts of the "SGML"-buffer.
2971 Fixed bug in server library (Windows version of statserv_remove).
2973 * Changed code so that it compiles as C++. The type definition
2974 of Odr_fun which is a member of Odr_arm was changed. The result is,
2975 that an explicit typecast is needed for the fun pointer when
2976 using Odr_arm - as in:
2977 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2979 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2981 Implemented the new structured date and time definition as approved
2982 by the ZIG. Added schemaId element to the specificTag in Espec-1
2983 (also approved at the last ZIG). Thanks to RVDM.
2985 Added some Object identifiers (RVDM).
2987 Changed the Update Extended Service (RVDM).
2989 Added command "refid" to client which specifies referenceId for
2990 the following requests.
2992 Implemented extended service handling for server. See ztest.c
2993 for an example as well as backend.h. New handlers are registerd
2994 in the Init handler.
2996 * Changed interface for sort in server.
2998 Added new members to statserv_options_block. It allows a server
2999 to read options from another source than just the command line. Thanks
3000 to Charles Woodfield.
3002 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3003 renamed to zboolean. Some C++ compilers complained about the name.
3005 Minor changes to gils.abs. Added index 's' (sort) on title
3006 and date/time-last-modified.
3008 --- 1.4pl2 1998/1/30
3010 Fixed bug in server library regarding inetd mode (-i). This bug
3011 was introduced by release 1.4.
3013 --- 1.4pl1 1998/1/29
3015 Added sort facility in client and backend server interface.
3017 Fixed problem with dependencies in Makefile(s).
3019 Fixed bugs for encoders/decoders of extended services and
3022 Implemented sub-tree feature for schemas. Sub-trees are
3023 referenced in *.abs-files. See explain.abs for an example
3024 of the use of this feature.
3026 Modified bib1.att; local attributes for ANY didn't include
3027 ANY itself (only affects use of the retrieval module).
3029 Fixed bug in plain SGML reader in function data1_read_node:
3030 tags with prefix "var" was incorrectly interpreted as variants.
3032 Added feature "sub-schemas" to enable references to - and definitions
3033 of - group of elements.
3035 * Removed member parent from type data1_element (in data1.h).
3037 Implemented function odr_nullval() that returns the value of
3040 * Removed member num_children from data1_node (in data1.h).
3042 Made NT service interface part of the server library. The
3043 function statserv_main uses the NT service when required and
3044 calls the statserv_start / statserv_close routines.
3046 Routine zget_SearchRequest and zget_PresentRequest fills
3047 resultSetName/Id member with "default" instead of "Default".
3049 Fixed memory leak in server. Request queue member wasn't freed.
3051 Fixed nmem_exit so that memory is freed.
3055 Revised the CCL parser utility to be thread safe.
3057 Added function, oid_ent_to_oid, to replace the function
3058 oid_getoidbyent, which is not thread safe.
3060 * Added nmem_init and nmem_exit to initialize and release
3061 NMEM resources. Function nmem_init should be called once in the
3062 initial thread before NMEM/ODR is used. statserv.c and client.c
3063 have been changed accordingly. The change was necessary to make
3064 NMEM thread safe. The NMEM memory pool is shared amongst threads
3065 in a process. Unix-based applications will still work fine without
3068 Added NT Services interface for the the Z39.50 (statserv) Server.
3069 Refer to the ztest.c source on the usage.
3071 Windows 95/NT port using MSVC5.0. Project files are included in the
3074 * Defined new 'global' handle for the retrieval (data1) system. The
3075 new handled, data1_handle, describes the state of the data1 system.
3076 This handle is passed as first argument to virtually all
3077 data1 related routines. The functions data1_create and data1_destroy
3078 creates and destroys a data1 handle respectively.
3080 Added ODR encode stream member to all backend request structures
3081 init, search, scan etc. This stream should be used to allocate all
3082 memory used for the response when thread safe operation is needed.
3084 Changed the comstack utility, cs_addstr, to be thread safe. The
3085 returned hostname string returned by the function is now part the
3088 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3089 function. The cs_straddr takes a COMSTACK handle as argument, so this
3090 function must be used after cs_create and before bind/connect.
3091 This function is thread safe.
3093 Moved test server to 'ztest' directory - generic server code still
3094 in 'server' directory.
3096 Made prefix query (pquery.c) utility thread safe.
3098 Added new function modifier YAZ_EXPORT to 'export' public DLL
3099 functions when using windows (see include/yconfig.h).
3101 Added definitions to the OID database (util/oid.c) (RVDM).
3103 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3105 Added call to ccl_rpn_delete in client program.
3107 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3108 release of RPN structure.
3110 Added support for C++, headers uses extern "C" for public definitions.
3111 With input from RVDM.
3113 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3114 Thanks to Ronald van der Meer (RVDM).
3116 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3118 Added support for private extensions to the OID database
3119 (oid_setprivateoids()). Thanks to RVDM.
3121 Added optional, physical ANY (key replication)
3123 Fixed null-reference problem in GRS-1 output filter.
3125 Proximity operator added to Prefix Query Format (PQF).
3127 In test client command "base" accepts multiple databases.
3129 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3133 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3135 Smallish bug-fixes in the new encoders/decoders (explain).
3137 Bug fixed in DeleteRequest.
3139 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3141 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3143 Added SOIF syntax (using private OID for now) to retrieval module and client.
3145 Added Update extended service.
3147 Added SearchResult-1 additional info structure.
3149 Added optional CCL (ISO8777) interpreter as separate module. Available
3152 --- 1.2 1996/6/10 (1st anniversary release)
3154 Added Summary record syntax. Lightly tested.
3156 Added OPAC record syntax. Untested.
3158 Added ResourceReport service encoders/decoders. Untested.
3160 Fixed bug in z_Unit - wrong tagging on unitSystem.
3162 Fixed bug in the DiagRecs decoder.
3164 Added options for max PDU size and session timeout to frontend-server.
3166 Added documentation of query-language parsers and other supporting utilities.
3168 [frontend-server] Added Attribute set to the bend_scanrequest API.
3170 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3171 surrogate diagnostics were generated.
3173 [retrieval] Allow multiple local values for attribute.
3175 [retrieval] Allow multiple attributes per element in .abs files. index type.
3177 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3179 --- 1.1pl2 1996/4/10
3181 Minor changes, mostly specific to Zebra's requirements (retrieval)
3185 Repaired bug in frontend server when running multiple listening
3186 endpoints in dynamic mode.
3188 z_External() now won't break if a known, ASN.1 value comes encapsulated
3189 in an octet-string. The value will pass through unmodified in an Odr_oct.
3191 Added a bit of code to the demo client to decode & display
3192 ASN.1-structured records represented in the octet-aligned branch of
3193 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3195 Added z_ext_getentbyref() to the ASN module. Doc updated.
3197 * Completed the SCAN definition in the ASN module. This may break SCAN
3198 code based on older YAZ-versions at compile-time. The fix is easy -
3201 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3202 under the SCAN definition. Remember to initialize this, server-people.
3204 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3205 that this does not extend to ODR and ASN.
3207 Comstack allows insertion of established socket (primarily for
3208 inetd-operation of servers). Doc updated.
3210 Front-end server can now start from the inetd in TCP mode. Doc
3213 --- 1.0pl4 1996/1/24
3217 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3218 the rank and record number.
3220 Adjustments to the frontend server.
3222 Fixed diagnostic BER dumper. It ignored the file argument.
3226 Various changes to retrieval module.
3228 Changed the union discriminators of the protocol files from enums to
3229 ints paired with #defines.
3231 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3234 *Changed operator in the RPN structure to 'roperator', again to avoid a
3237 Fixed problems in Explain decoders/encoders.
3239 --- 1.0pl2 1995/12/6
3241 Memory bug in log module fixed.
3243 --- 1.0pl1 1995/12/5
3245 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3247 Bug in Explain DatabaseInfo module fixed.
3249 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3253 The shift to v1.0 signals that we now consider the *core* functionality
3254 of YAZ reasonably stable (the core being more or less equivalent to
3255 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3256 tested (Explain not at all - though that will happen soonish).
3258 Minor changes to code to support Windows port.
3260 Various minor changes after we're getting to use GRS-1 & co. more.
3262 Added Espec-1 format.
3264 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3265 of the protocol and it cannot be selected when encoding (maps into 'string'
3266 when decoding). Needed to talk to some servers.
3268 Demo client can request simple element set names.
3270 Added Diagnostic Format encoders/decoders.
3272 Added simple Close handling to frontend server (no hooks for resource
3273 reporting yet), and demonstration client.
3275 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3277 --- 1.0b3 1995/08/24
3279 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3280 handled incorrectly when records were requested in the searchResponse. This
3281 will only affect you if you use the frontend-server.
3283 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3284 Test-client will ask for and print GRS1. Ztest will return dummy records
3287 Added Explain encoders/decoders to the service-level API. Untested.
3289 Added Extended Services: Item Order encoders and decoders to the Service-
3290 level API. Untested. We could use a recent copy of the pertinent bits
3291 of the ILL protocol to add those bits.
3293 Added diagnostic format 1 encoders/decoders to the service-level API.
3296 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3297 odr_cons.c, which causes a more correct output.
3299 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3300 was always set to 0 when no records were requested in the searchRequest.
3302 * Added better external-handling. This shouldn't harm old code that
3303 *encodes* externals. It can break code that looks for a
3304 'single-ASN1-type' representation, since those types that are known
3305 are now decoded immediately. Look at the SUTRS sample code in
3306 seshigh.c and client.c. Documentation updated.
3308 Handling of structured records in bend_fetchresponse. Length -1 marks
3309 structured record, type is deduced from format field.
3311 --- 1.0b2 1995/06/27
3312 Fairly quick maintenance release to add SUTRS support.
3314 Fixed handling of SUTRS records in the demonstration client.
3316 * Added format field to the bend_fetchrequest and bend_fetchresponce
3317 structures of the backend API (frontend server). When the record is
3318 returned, the value of the format field is mapped to an OID. The
3319 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3320 of the record. The special value VAL_NONE in the bend_request means
3321 that no specific format was requested by the client. Documentation
3322 updated accordingly. Test server (ztest) will return a fixed dummy
3323 SUTRS record if your client requests SUTRS.
3325 Documentation updated accordingly.
3327 You can now set external libraries and RANLIB support in the top-level
3331 First public release.
