3 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
4 mode at all. Probably never did.
6 Make a new version of ztest.pem that, at least, is not expired.
10 Fix description of CCL directive 'case'.
12 More tight checking of form arguments (yaz_uri_to_array). Makes
13 YAZ better at rejecting big and/or bad POSTs.
15 SRU decoding does not report more than up to 10 invalid arguments.
17 rpn2cql: less quotes in generated terms. Semantics unchanged, but
18 it's prettier this way.
22 New utility yaz_decode_init_diag. Defined in proto.h.
24 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
25 given for unix local socket.
26 The COMSTACK string for doing so is:
29 unix:/myfile:tcp:localhost:9999/mybase
30 unix:/myfile:localhost:9999/mybase
31 unix:/myfile:http://fakehost/mybase
33 debian: Use dpkg-buildflags in build process.
37 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
38 global's SRU service uses a recordPosition scheme starting from zero.
39 First record's position should be one
40 according to the standard.
44 Allow more namespaces for SRU. This is to allow, for example, an
45 incorrect namespace returned from server
46 http://services.igi-global.com/sru .
48 Minor fixes for compilation on Windows.
52 daemon: log total number of bad signals from child on stop so that it
53 is more easy to spot problems with child worker processes.
55 retrieval: empty backend name attribute omits element set
56 from being used in retrieval.
60 Implement Solr sort strategy "solr", similar to sru11 sorting.
61 This will implement the correct parameters on Solr requst to do
66 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
69 MARC: Extra/missing indicator handled for MARCXML.
70 The indicator length is given in header and is the same for the
71 whole record. If attributes ind1, ind2 are missing, then content
72 character defaults to blank. Extra indicator attributes (beyond)
73 indicator length are treated as an error.
75 Reformat: delete trailing whitespace
79 MARC: fix non-ASCII characters for leader. This is to ensure we can
80 generate XML in UTF-8.
82 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
83 in one node with structure word.
87 yaz-json-parse: JSON output may be pretty printed by using option
90 Increase default value of max message for Z39.50 Init for GFS, ZOOM
91 and yaz-client. Old value was 1 MB. New value is 64 MB.
95 yaz-client: don't display bogus records from SRU servers. Some SRU servers
96 return more records than given by *maximumRecords*. Skipping those in
99 record_render: simplify buffer return handling and fix at least one bad
100 memory reference, that broke the test_embed_record sometimes.
102 Allow http://user:pass@host notation for yaz_url_exec.
104 zoomsh: allow shell command to be executed. Via the system(3) call.
106 yaz_poll: Allow num_fds == 0
108 yaz-client: fix bad encoding of "itemorder item". The itemorder
109 item <no> - command forgot to use length of encoded Item Request
110 package. Error present since YAZ 3.
112 yaz-ztest: fix bad usage of session handle. Bug was introduced when
113 result sets were saved (271a9c83).
115 SRU recordPacking: guess record packing in response rather than looking
116 at the recordPacking element which, OF COURSE, changed semantics in SRU
119 Decode SRU 2.0 responses. The official namespace for responses, according
120 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
121 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
122 nature.com's server, however, usee namespace
123 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
124 we are now using a glob-expr to match up the namespace. ZOOM C and
125 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
126 I can not find a single real example showing the "real" namespace in
127 the documentation from OASIS. The namespace for requests is different
128 from responses, but this is not added to YAZ yet, when we don't encode
131 --- 4.2.35 2012/06/26
133 zoom/record_render: add support for Base64 decoding fo MARC records
134 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
135 which will decode base64 + ISO2709 marc-8 encoded material from text node
138 --- 4.2.34 2012/06/07
140 Add missing definitions ZOOM_resultset_get_facet_field_by_index
141 and ZOOM_resultset_facets_names.
143 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
146 Change APDU dump printing to avoid long leading blanks. For levels 16
147 or larger the level is shown and the indentation is truncated but
148 recursed with modula 8. This makes it still reasonable easy to read
149 - even for nested BER dumps.
151 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
152 return 0 (incomplete package) in case where the BER package was
153 considered too nested (return value of -2).
155 dumpber: lines of level 15 are not indented further. Two spaces per
156 indentation; indentation 15 or more is indented to a fixed indentation
157 and augmented with a level=<no> indication.
159 zoomsh: increase max size of command+args
161 GFS: No limit in RPN buf size in CQL to RPN conversion.
163 --- 4.2.33 2012/05/09
165 New function for daemon utility, yaz_daemon_stop .
167 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
169 --- 4.2.32 2012/04/25
171 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
172 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
174 --- 4.2.31 2012/04/23
176 YAZ daemon utility relays SIGUSR1 to child process.
178 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
179 would result in en empty database list - which in turn would result in
180 encoding failure for search.
182 Fix reading beyond string in yaz_sort_spec.
184 --- 4.2.30 2012/04/11
186 Add two new SRU diagnostics:
187 236: Access to specified database denied
188 1015: Init/AC: Maximum number of simultaneous sessions for Userid
190 Document the very useful ZOOM-C option "apdulog".
192 CQL to RPN: term may be passed through verbatim. This is enabled with
193 truncation.cql . The assumption being that the term is already CQL.
195 --- 4.2.29 2012/03/20
197 record_conv: leader spec may be given for marc element.
198 The leader spec is given as attribute leaderspec for element marc.
199 For example to convert a MARC21 record from MARC-8 to UTF-8:
200 <marc inputformat="marc" outputformat="marc"
201 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
203 record_conv: allow user-XSLT params. For example:
204 <xslt stylesheet="MARC21slim2DC.xsl">
205 <param name="myparameter" value="myvalue"/>
206 <param name="otherparameter" value="othervalue"/>
209 record_conv: fix error handling for missing marc charsets.
211 CQL: fix extra terms in wrong order.
213 --- 4.2.28 2012/03/06
215 record_conv: modify new API for conversion types. The conversion types
216 may be passed in new functions yaz_record_conv_configure_t and
217 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
219 Avoid mixed statement/variable declare; fixes compilation with Visual
222 --- 4.2.27 2012/02/28
224 Add non-standard SRU diagnostic: 235: "Database does not exist".
225 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
226 Update SRU to Bib-1 diagnostic maps accordingly.
228 CCL: add two new diagnostics for unsupported masking. The new
229 diagnostics are: "Embedded truncation not supported" and
230 "Single charcacter mask not supported".
232 --- 4.2.26 2012/02/23
234 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
236 --- 4.2.25 2012/01/11
238 Build YAZ for Ubuntu Oneiric.
240 CCL: allow parantheses for proximity operands. For example CCL query
241 (a) % (b) is now allowed.
243 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
244 marked dead, rather then being destroyed. If not, the session memory is
245 being free'd before the search/scan handler is finished. Also destroy
246 'request' memory in request_release rather than in various places,
247 which resulted in leaks from time to time.
249 --- 4.2.24 2011/12/21
251 cql_sortby_to_sortkeys: honor sort prefix.
253 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
254 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
255 The rpn2cql family of functions now always returns quoted CQL terms.
257 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
259 --- 4.2.23 2011/12/15
261 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
262 sequence is treated as one. For example, &&a=b&&&c& is identical to
265 --- 4.2.22 2011/12/05
267 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
268 APDUs for a connection to a WRBUF.
270 --- 4.2.21 2011/11/23
272 Fix cql_sortby_to_sortkeys. Completely broken before.
274 Make CCL's @truncation work again.
276 --- 4.2.20 2011/11/09
278 New ZOOM connection setting: tproxy. It's like proxy, but does not
279 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
280 to set resolved address + port for a connection outside ZOOM itself.
282 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
284 --- 4.2.19 2011/11/07
286 Fix uninitialized variable in Solr spell support (could cause SEGV
287 for SRU response decoding).
289 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
290 back-end's addinfo through into the ZOOM response addinfo.
292 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
293 they are separated by a colon and a space rather than simply
296 --- 4.2.18 2011/10/28
298 Add support for Solr spell-checking/suggestions through ZOOM.
299 If a Solr target has been configured correctly for spelling-checking
300 and suggestions, these will now be returned on the ResultSet option
301 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
303 --- 4.2.17 2011/09/28
305 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
306 with a flag whether to substitute escape sequences or not.
308 --- 4.2.16 2011/09/22
310 Fix nmem_strsplit_escape to substitute escape char properly.
312 New option for zoomsh -e , which makes it abort on first error and
313 return process exit code to indicate success/failure.
315 YAZ options utility supports special option -- which makes all it treat
316 all following arguments as non-options.
318 --- 4.2.15 2011/09/16
320 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
321 searched if absolute filename is given.
323 Fix conv_xslt() error-reporting when stylesheet is not found.
324 (The value of fullpath is meaningless in this situation.)
326 --- 4.2.14 2011/09/07
328 Fix problem in CQL sort node creation: un-initialized memory.
330 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
331 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
332 CQL sortby depending on whether Type-1 or CQL is actually sent to the
335 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
336 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
338 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
339 will make it possible to use both single-character mask (#) and wildcard (?)
340 in CCL . Throw diagnostic for left truncation because that is not supported
343 --- 4.2.13 2011/09/01
345 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
346 cases using escapes (\-sequences) and masking.
348 PQF parse fix: A trailing backslash followed by end-of-string (\0)
349 would result in a read one byte beyond string.
351 rpn2ccl may use Z39.50 masking for terms (t=z).
353 ICU check fix. Don't include library -lCrun on Solaris, unless present.
355 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
356 not --cppflags (which seeems like an error in icu-config).
358 --- 4.2.12 2011/08/27 RPM package only
360 cql2ccl: fix conversion of terms: operator characters were not
363 --- 4.2.11 2011/08/25 RPM package only
365 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
366 CCL parser will map both # and ? to their regular expression
367 quivalents (. and .*).
369 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
370 of reserved CQL characters.
372 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
373 is, so that they are passed through.
375 --- 4.2.10 2011/08/24
377 ZOOM SRU mode: more aggressive re-connect.
379 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
380 made available as a utility function, declared in <yaz/logrpn.h>
382 rpn2cql_structure() supports proximity nodes (except that the Type-1
383 proximity node's "exclusion" binary is ignored, as there is no way to
384 express that in CQL). Fixes bug #4564.
388 Fix SEGV that could occur if set command of zoomsh was given without
389 value (2nd argument).
391 Fix SEGV that could occur if unsupported transport was given for
392 COMSTACK - say https (when SSL was unavailable).
394 Build yaz-url on Windows too.
398 New utility to get web content. Header is url.h. A command line tool
399 yaz-url is part of the distribution and packages.
401 Fixes for SSL COMSTACK (when gnutls is in use).
403 New functions yaz_base64{encode,decode}. Header is base64.h.
407 ZOOM C includes HTTP response buffer as additional info if it fails
408 to decode the SRU response.
410 Make wrbuf_json_puts available.
414 zoom: throw diagnostic for invalid value for option "sru". Before a
415 bad SRU request was sent.
417 Adding new utility wrbuf_vp_puts.
419 Add cclxmlconfig.obj to win/makefile. It was missing completely.
423 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
424 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
425 redirect was used at the same time.
427 MARC line mode decoding: be less picky about length given - first
428 5 digits of header that is.
430 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
432 Changes to decoding of SRU records: a record with recordPacking=xml is
433 modified with a new root element <yaz_record> if the recordData contains
434 multiple children elements. This is to make the record XML parseable
437 RPN to SOLR conversion: encode special characters.
439 Generic Frontend Server: fix uinitialized member, stepSize.
443 Fix a bug in SRU decoding of records.. The database records stored
444 had un-initialized memory, but it would only be seen with yaz_record_render
445 and type_spec="ext" .
447 Fix a bug in ccl_qual_dup introduced in 4.2.3.
451 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
455 Add new utilities to convert from CQL to CCL . These utilities have
456 prefix cql_to_ccl defined in cql.h.
458 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
459 lead to memory heap corruptions when ICU utilities were in use.
463 Make compilation work without Libxml2.
465 yaz-client: remove redundant blanks in display of searchResult-1 term
470 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
471 resulting CQL node (tree) in a new node CQL_NODE_SORT.
473 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
474 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
475 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
476 Note that the CQL sortby spec is only converted when the GFS is already
477 converting from CQL to RPN (cql2rpn element).
479 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
480 specify whether to collapse delimitors or not. The existing nmem_strsplit
481 do collapse (collapse parameter = 1).
483 Windows installer: For NSIS, set InstallDir depending on x86/x64.
485 Rename internal func yaz_use_attribute_create. While non-static, this
486 function is not declared in a public header.
490 Add -lCrun when linking with ICU on Solaris.
492 More quicks character set conversions for OPAC records.
496 fix problem with record_render: records were converted (character set
497 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
501 SRU: add methods for handling DADS SRU-proxy facets.
503 Separate OPAC record character set for ZOOM_record. yaz_record_render
504 allows a character set given as charset=from/opacfrom,to where 'from' is
505 the character set of a bibliographic record, 'opacfrom' is character set
506 of OPAC record and 'to' is the target character set.
510 yaz-client: show may XML format records. Command show followed by 'format'
511 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
514 src/stemmer.c: Avoid using unnamed union. It is not supported by some
517 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
520 Update yaz.spec to operate on both SLES11 / Centos 5.5.
522 RPM: Release includes 'indexdata' name. Use indexdata in release name so
523 this package can be distinguished from other vendors.
525 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
526 as determined by configure
528 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
530 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
531 returns no error and no record, the present request is considered
532 partial (only a subset of the records could be returned by backend), and
533 so it is appropriate to set Present Status to partial-4.
537 Move yaz-config man pages to section 1.
539 More documentation about SOLR.
541 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
542 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
543 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
544 peers on some Linux systems. However, in general that does not work
545 so YAZ can not rely on that to work. Debian changed behavior in this
546 respect from Debian lenny to Debian squeeze (still testing as of Oct
548 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
550 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
554 Fix yaz-config output: echo_source not set correctly by configure.
558 SOLR WebService support for yaz-client and ZOOM.
560 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
562 --- 4.0.12 2010/08/17
564 Z39.50 facet support. Facet specifications are passed for search in
565 other-information with ASN.1 as defined in facet.asn and OID
566 .10.1000.81.5 . Facets are expressed as an Attribute list as known
567 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
568 3 is limit (number of entries to get in response). yaz-ztest returns
569 dummy facets if a client asks for them.
571 --- 4.0.11 2010/07/09
573 CCL fixes: bug 2895 and bug 3539.
575 GR1-display: add comma in display - was removed by mistake in
578 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
580 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
582 --- 4.0.10 2010/06/18
584 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
585 result set from a connection. The result set will be on its own
586 thereafter; no operations on it will perform retrievals from a target.
587 Only cached copies are returned.
589 ZOOM C:fix case for HTTP servers responding with Connection:close.
590 Ensure that if there is a current task it is resumed (like fetching
591 more records in a result set) . Bug #3484.
593 PQF parser: use odr_atoi for Odr_int (not atoi)
595 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
596 values that contain any non-digits are treated as string attributes
597 (previously decoding only checked for leading character ([0-9]). PQF
598 encoding: attribute string values are not surrounded by double-quotes.
602 New utility for managing threads - thread_create.h.
604 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
605 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
606 but YAZ' implementation do.
608 Fixes for yaz_cond-functions on Windows 7.
610 DLL export more symbols.
612 zoomsh: show record do NOT render opac.
614 Remove *.la files from Debian and RPM packages.
618 Debian package libyaz-dev depends on libgnutls-dev again (was
619 removed in YAZ 4.0.6, but due to Libtool it is still needed
620 even though yaz-config do not list libgnutls libs).
622 ZOOM: Use only one WRBUF for returning string results for
623 ZOOM_resultset. Reduces memory usage for ZOOM in general.
625 ZOOM: ZOOM_connection do not use a shared pointer to
626 ZOOM_resultset after ZOOM_resultset is destructed by
627 user. Reverts to YAZ 4.0.4 behavior.
631 record-conv: fix problem with at least one XSL conversion -
632 due to probably incorrect usage of XML XSL documents.
636 Fix yaz-config for static mode and the use of SSL (gnutls).
640 Forward decl timeval struct in mutex.h and gettimeofday.h.
642 yaz-config: fix 'static' mode linking.
646 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
647 are wrappers for pthreads or Windows. For Windows these are put in
648 a separate DLL: yaz_cond4.
650 libyaz.la (whole source) is compiled with thread. If thread support
651 is enabled enabled, all source of YAZ is compiled with treading support.
652 This allows core utilities such as yaz_log to use thread facilities.
653 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
654 thread utilities. This commit moves mutex utilities (mutex.c) from
655 libyaz_server.la to libyaz.la.
657 yaz-json-parse displays leading text until error.
661 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
662 patch from Giannis Kosmas.
664 SRU: no longer URL encode SRU database. The URL for an SRU server is
665 a URL and such is alreeady encoded - at least when given with leading
666 http:// or https://. This reverts behavior to YAZ 3.0.50.
668 Support for new MARC XML notation TurboMARC which like MARCXML is a
669 complete representation of MARC/ISO2709.. This one, however, is more
670 compact and allows for faster processing with XSLT. TurboMARC can be
671 used in the marcdisp.h API, from the yaz-marcdump utility and from
674 yaz-ztest can be configured - via the database - to perform certain
675 delays when it performs operations search, present and single record
676 fetch. This allows testers to make yaz-ztest act as a real or even slow
677 Z39.50 server. Refer to the yaz-ztest man pages for details.
681 wrbuf_destroy allows NULL WRBUF passed to it.
683 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
685 Add ZOOM_connection_close.
687 No fixed size buffers for ZOOM shell - bug #3257.
689 tstodr: make it work on s390 platform.
691 New icu iterator-functions. The new icu_iter-functions makes it possible
692 to use ICU chains from many threads.
694 yaz-client: better syntax check for show command.
698 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
701 New simple local-file XML include facility which allows file glob-patterns.
702 Refer to yaz/xml_include.h.
704 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
707 ZOOM_record_get supports new parameter "format" which makes it format XML
710 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
711 JSONText in ECMA-262) is JSONValue, not JSONObject.
715 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
716 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
718 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
719 POSIX/Unix builds .so with major version 4.
721 Remove old LOG_-defines from log.h. They have been obsolete and
722 undefined by default for the last 5 years.
724 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
726 GFS: Remove socket (int *fd) from search_rr handler. The socket
727 descriptor ptr is a facility that allowed a search handler to supply
728 a socket which would serve as a callback - when search was complete.
729 This facility has now been in use for years.
731 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
732 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
733 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
734 returns 'const char *' rather than 'char *. The returned string is
735 read-only and should not be modified by applications. COMSTACK cs_close is
736 now a void function - it no longer returns int. No applications check for
737 the value and the implementations has always returned 0.
739 ZOOM: use size_t for scan hit counts and str size. Functions
740 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
741 occ (hit count) and len (string length) are now of type size_t pointer
742 rather than int pointer. This is to be able to represent large hit counts
743 and to also just to use the proper type for string length (strlen result).
745 New JSON parser. Refer to include/yaz/json.h .
747 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
748 Used to be int in some cases. Many wrbuf_-functions used to return an int
749 indicating some length.. These return values were never used. And so they
752 ODR: odr_malloc, odr_total now takes size_t for size.
754 clone_z_type: fix leak; occurred for encoding failures.
756 --- 3.0.52 2009/12/03
758 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
759 bug was introduced in 3.0.51.
761 --- 3.0.51 2009/12/02
763 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
765 tcpip comstack: fix leak for getaddrinfo.
767 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
768 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
769 Decoding of SRU "path" database is performed by private function
770 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
771 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
773 yaz-client: honor base command for SRU. Change when database setting
774 is applied for SRU and ensure it is kept when a connection is reset.
775 Change also the way errors are displayed or SRU (decoding of packages).
777 --- 3.0.50 2009/11/02
779 Add support for extra request / response data for SRU codecs and GFS.
780 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
781 for extra data response buffer and length. For the GFS, both request
782 and response data (XML) is carried in extra_args and extra_response_data
783 for the search handler. Patch by Ko van der Sloot.
785 ZOOM: For queries that cannot be converted to the specified rpnCharset,
786 ZOOM now returns a diagnostic on the client-side ('invalid query' /
787 10010). This fixes bug #2113.
789 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
790 cmdfile included a 'quit' command that would result in a memory violation.
792 --- 3.0.49 2009/10/01
794 Make a number of functions defined in xmlquery.c static. These have
795 never been declared in a public header file (yaz/xmlquery.h) and was
796 made public by mistake.
798 Improve speed of character conversions (iconv utilities). This makes
799 conversions from MARC-8 faster.
801 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
802 unless type desired is "raw". This will prevent type "xml" from
803 returning ISO2709 .. Which obviously can not be XML parsed.
805 Fix memory leak in ZOOM that would occur if option apdulog was used
806 on a re-used connection.
808 Frontend server logs HTTP requests.
810 Frontend server now sends Z39.50 close when it times out (sesssion has
811 been idle for too long). Versions 2.0.30 and earlier also sent close.
812 But due to a mistake this was disabled in all versions after that, i.e.
813 the server would just close the socket immediately.
815 yaz-client emits a better message when receiving an unrecognised
816 userInformationField.
818 Skip zero-length subfields when decoding ISO2709. This rare case happens
819 if a record has two FS characters in a sequence. Without this patch
820 there would be a reference beyond char array in using_code_len fragments
823 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
825 --- 3.0.48 2009/08/28
827 The show command offered by the zoomsh command now takes a 3d optional
828 parameter type which is what is passed to ZOOM_record. If the type
829 argument is omitted, "render" is used.
831 RPN to CQL conv may use USE string attributes (bug #2978).
833 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
835 --- 3.0.47 2009/07/08
837 Function yaz_xml2query allows a diagnostic element in the PQF XML
838 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
839 code and additional info respectively.
841 The BER BOOLEAN is now the integral type Odr_bool which still happens
842 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
843 typedef'd to Odr_int. This is still an integral 'int', but it may be
844 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
845 ASN-1 compiler as well as programs has been updated to use the new types.
847 --- 3.0.46 2009/06/08
849 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
850 only the bibliographic record was rendered. For type=opac, an OPAC
851 record is only returned if it is present.
853 iconv: small fix for encoding of advancegreek.
855 yaz-client: avoid double display of SRU/SRW records (bug #2798).
857 yaz-client: option auto_reconnect=on really reconnects.
859 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
861 server: avoid null ptr ref for for yaz_poll errors.
863 build: fix RPM build for RHEL 5.3.
865 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
867 --- 3.0.45 2009/03/31
869 Fixed bug #2709: TCP connect returns Invalid argument.
871 Fixed compilation for mingw.
873 Honor charset for raw records (ZOOM_record_get).
875 Fixed use of errno for threaded mode that was seen on Solaris 10.
877 Fixed argument passing with blanks in value for Windows Service.
879 Disable YAZ' own log rotate by default (no 1 GB limit).
880 The variable l_max_size which specifies the log file limit is set to 0
881 (DISABLED): This is due to the fact that YAZ is most often deployed using
882 logrotate. Also YAZ can not perform log rotate because of unsufficient
883 permissions (setuid).
885 --- 3.0.44 2009/02/17
887 List supported encodings in man page for yaz-iconv.
889 Fixed missing SSL libs for --libs output
891 Re-established OID record syntax application-xml. Nobody should use it
892 but we don't want to change soname because of this symbol being absent.
894 --- 3.0.42 2009/02/02
896 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
898 Added member named_result_sets for init handler struct for the GFS. This
899 allows a server to disable named result sets.
901 Removed OID record syntax application-xml.
903 Added support for rule-based transliterator for ICU wrapper of YAZ.
905 Fixed bug #1902: yaz-icu XML output.
907 Make YAZ checks Emacs friendly.
909 BITSTRING value shows value. Bug #2346.
911 ISO2709 decoding: skip control characters from indicator data.
913 Omit sort key by default in yaz-icu's output.
915 Allow combined single char options (again) for YAZ' options function.
917 Utility yaz-marcdump got option to display YAZ version (-V).
919 Allow YAZ to use ICU 3.4.
921 Added new ICU test case which illustrates removal of diacritics.
923 --- 3.0.41 2008/12/29
925 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
927 --- 3.0.40 2008/12/29
929 For configure, using option --without-xml2 also disables Libxslt/Libexslt
932 Fixed bug #2352: yaz-marcdump crashes for certain record.
934 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
936 Added support for Danmarc2 to UTF-8 conversion.
938 Added support for ISO5426 to UTF-8 conversion.
940 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
941 implementation version.
943 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
945 --- 3.0.38 2008/11/10
947 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
948 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
950 ZOOM C now interprets databaseName option for ZOOM connection as path
953 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
955 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
957 Dummy Libxml2 types no longer defined in headers of YAZ'.
959 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
962 --- 3.0.36 2008/09/26
964 Various ODR chapter fixes.
966 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
968 Added missing source for Windows compilation, mutex.c.
970 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
972 For SRU connections in ZOOM all records up to "count" are now fetched.
974 Fixed crash in generic frontend server (and yaz-ztest) which occurred
975 in Windows due to bad error handling for Libxml2.
977 Added facility for sending arbitrary records (ASN.1 any) using
978 ZOOM C's Extended service update. Patch by Sam Reynolds.
980 New options for ZOOM C's connection, logapdu which makes ZOOM log
983 --- 3.0.34 2008/06/18
985 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
987 --- 3.0.32 2008/06/12
989 Fixed memory violation that could occur when decoding UTF-8. This bug
990 was only present in 3.0.30 of YAZ.
992 --- 3.0.30 2008/06/06
994 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
995 GNU TLS is used by default (if found).
997 yaz-ztest returns OPAC records if a client asks for OPAC.
999 Improved speed of MARC-8 encoding.
1001 Added support for lossy and loss-less MARC-8 encoding.
1003 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1005 Added new Windows Service wrapper (sc).
1007 yaz-client's itemorder command may now send a file.
1009 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1011 Added new function yaz_log_xml_errors.
1013 Allow (but warn) unknown XML attributes in MARCXML parsing.
1015 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1017 The UTF-8 to MARC-8 conversion now uses a different set of characters
1018 for Greek symbols. Bug #2120.
1020 --- 3.0.26 2008/02/21
1022 Added yaz_daemon (daemon.h).
1024 Fixed bug #2068: pkg-config trouble
1026 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1028 --- 3.0.24 2008/01/28
1030 Document --with-xml2 option.
1032 Added OPAC XML XSD (etc/opacxml.xsd).
1034 Allow glob mask for name attribute in retrieval element for the
1035 generic frontend server's retrieval facility.
1037 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1038 except POLLIN/POLLOUT.
1040 Fixed error handling in cs_listen. Bug #2037.
1042 --- 3.0.22 2008/01/20
1044 Fixed version in yaz/yaz-version.h.
1046 Fixed bug #2027: Crash when closing connection.
1048 Changed configure so that ICU support is only enabled if only ICU
1049 and Libxml2 is available (because the ICU chain is XML based).
1051 --- 3.0.20 2008/01/15
1053 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1054 is built. Only this DLL depends on the ICU runtime.
1056 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1057 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1059 Changed license of CCL module to 'Revised BSD'. After consultation with
1060 remaining members of the original EUROPAGATE consortium, we are re-issuing
1061 the CCL module without a separate license. The software was developed by
1062 Index Data as part of a research project. The special license was included
1063 to help feed usage information back to the project consortium to support
1064 project evaluation. At this time, the project consortium has long-since
1065 disbanded, and the majority of the original principals have retired. At the
1066 same time, we have significantly modified the software during the following
1067 years, to the point where very practically no original code remains. To
1068 simplify re-use of the software, we have contacted those members of the
1069 consortium who could be reached, and agreed to re-issue the module as a
1070 proper part of the YAZ package.
1072 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1074 CQL closer to being version 1.2 compliant. CQL also allows free-form
1075 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1078 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1079 bug could make Extended services handling crash in the ZOOM layer. This
1080 bug was only present in YAZ 3.0.18.
1082 --- 3.0.18 2007/12/19
1084 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1087 yaz-marcdump reads and writes collection wrapped records.
1089 Handle OPAC for record conversion module.
1091 Fixes for ICU wrapper.
1093 Allow ICU libs to be controlled with --with-icu .
1095 --- 3.0.16 2007/11/12
1097 Added yaz_poll which is a wrapper for select/poll. When poll is available
1098 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1099 sockets to be in use.
1101 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1102 functionality through an XML based configuration (ICU chain). This system
1103 is useful for search facilities such as Pazpar2 and Zebra that needs to
1104 perform tokenization of indexed material. The ICU code in a separate
1105 library libyaz3_icu.a.
1107 Added HTTP tunnel facility for COMSTACK, bug #1752.
1108 This is a facility that allows a Web proxy, such as squid, to tunnel
1109 Z39.50 traffic. This facility is "transparent" to must applications
1110 using YAZ. It's enabled by using pseudo transport connect: followed by
1111 the proxy address, followed by command, then follwed by he regular
1112 "virtual" addresss. For example,
1113 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1115 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1117 --- 3.0.14 2007/09/21
1119 Fixed bad memory reference in ZOOM_record - cuased by member not being
1120 initialized. This was a problem only in YAZ 3.0.12.
1122 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1123 fields were not removed.
1125 Changed the way C code is generated from codetables.xml. Made a MARC-8
1126 conversion trie for each characterSet section rather than codeTable.
1127 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1128 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1130 --- 3.0.12 2007/09/12
1132 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1133 from ZOOM_record_error).
1135 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1137 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1139 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1141 Better SRW-to-Bib-1 diagnostic mapping.
1143 ZOOM C and yaz-client announces SRU version 1.2 by default.
1145 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1148 Fixed in yaz_sru_decode to allow other version than 1.1.
1150 --- 3.0.10 2007/08/22
1152 Added support for SRU scan for ZOOM.
1154 Added support for the use of the older versions or Extended Service
1155 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1156 set to the version , 1=first, 2=second, 3=third. The third version is
1157 what ZOOM C has used so far. And that, obviously, is the default.
1159 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1160 therefore in Zebra and in SimpleServer-based applications). The new
1161 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1162 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1163 which is passed into the back-end search callback function.
1165 Added support for HTTP Basic authentication in clients: the SRU/W
1166 codec encodes the username/password elements of the PDU structure
1167 appropriately, and these may be set using the "user" and "password"
1168 options in ZOOM-C applications (the same options that are used for
1169 Z39.50 authentication).
1171 --- 3.0.8 2007/06/25
1173 Fixed bug #1208: SSL appears to be broken in ZOOM.
1175 Fixed bug #1206: Libxml2 include path weirdness.
1177 Added oid_name_to_dotstring.
1179 Allow elementSetName to be specified for ZOOM C record update.
1181 Allow waitAction to be specified for ZOOM C based for Extended Services.
1183 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1184 syntax OID. Bug introduced in YAZ 3 series.
1186 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1188 --- 3.0.6 2007/06/06
1190 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1191 directory. yaz-client now reads commands from file given by option -f
1192 if specified; then tries to read .yazclientrc in current directory.
1193 Failing that, it reads .yazclientrc from user's home directory.
1195 Added support for correlationInfo Note and ID for Record Update via
1198 Added yaz-client command querycharset which specifies character set for
1199 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1200 (termListAndStartPoint).
1202 Charset ISO5428:1984 is an alias for ISO5428-1984.
1204 Implemented a way to perform scan in a result set using Z39.50. This
1205 is achieved by attaching the result set name in the characterInfo
1206 (type InternationalString) of OtherInformation in the Scan Request PDU.
1207 The result set is identified in the otherinformation by the new OID:
1208 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1209 This allows for scan in result set and faceted search . Zebra did some
1210 of this in the APT term using attribute type 8 and value being result
1211 set. Using the OtherInformation approach for this is cleaner and easier
1212 to work with in proxies and the like. This facility can be used in
1213 yaz-client using new command setscan which takes a result set as first
1214 argument, start position (APT) as second.
1216 Changed decoding of SRU XML packed records to deal with servers that
1217 have recordData with XML data with multiple root nodes. Also make
1218 comparison for recordPacking case insensitive. Again, one server
1219 returns "XML" where others return "xml".
1221 For SRU responses allow Content-Type application/xml as well as text/xml.
1223 --- 3.0.4 2007/05/21
1225 Fixed bug in character set conversion of BER strings. Bug introduced
1228 --- 3.0.2 2007/05/08
1230 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1232 For OID class, use oid_class consistently.
1234 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1237 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1238 character set for bibliographic information interchange". By Giannis Kosmas.
1240 Added documentation on new OID API.
1242 --- 3.0.0 2007/05/02
1244 Changes to generic frontend server interface: added new member
1245 'query_charset' for bend_initrequest structure. A backend init handler
1246 should set this member to its native character set for query terms.
1247 When defined, the frontend server logic will announce this character set
1248 to a client if the negotiationModel bit is set by the client. All server
1249 implementors are encouraged to specify this. If a backend server does not
1250 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1252 Added CCL utility to remove terms (stop words) from resulting RPN
1253 tree. This is handled by functions with prefix ccl_stop_words_ .
1255 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1256 terms in RPN queries.
1258 Clean-up the CCL API. Moved some internal structures from ccl.h to
1259 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1260 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1261 This is replaced by ccl_parser_find_str which takes a string instead.
1263 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1264 libyaz.la is the core of YAZ except the generic frontend server and
1265 does not depend on POSIX threads anymore. libyaz_server.la is the
1266 generic frontend server facilities and uses POSIX thread functionality
1267 if available. The libyaz.la no longer depends on POSIX threads because
1268 the number of global structures is limited. NMEM no longer re-uses blocks
1269 between threads ; it simply free's memory immediately but allocates in
1270 "large" chunks as usual. We don't expect any performance penalties
1271 because of this. The yaz_log system is still using a global log_level so
1272 caution must be taken when modifying it with yaz_log_init_.. +
1273 yaz_log_mask_str. This, however, should not cause any trouble because
1274 these functions are called during initialization of application code
1275 anyway. `yaz-config --libs server` returns libs for server applications;
1276 `yaz-config --libs` returns libs for non-server applications.
1278 New OID database - with public definitions in oid_db.h. Removed old OID
1279 database including the head oid.h and definitions such as enum oid_value
1280 and struct oident. The new OID database uses the same string names as
1281 before but the 'protocol' is gone. There are now only two representations
1282 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1283 converts from string to OID; functions with prefix yaz_oid_to_string
1284 converts the other way.
1286 Change to emit_term() in CQL-to-PQF query translation: when a term has
1287 the /regexp relation modifier, do not process it for leading and
1288 trailing "^" and "*", which have quite different meanings in regular
1291 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1292 write handlers no longer carries a 'last' parameter. This will make
1293 yaz_iconv flush "less" characters. A flush is performed by call to
1294 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1296 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1297 removed, because function yaz_query_to_wrbuf does the same.
1299 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1300 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1302 Deprecated MARC utility functions removed.
1304 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1307 Branch split: YAZ_2_1_55_branch
1309 --- 2.1.54 2007/03/16
1311 Fix to ZOOM-C so that transparent reconnection is properly handled on
1312 connections that are in asynchronous mode.
1314 Fixed compilation on OpenBSD 4.0.
1316 Large strings in GRS-1 records are now properly displayed in yaz-client.
1318 Added character conversion support for "advancegreek"; based on patch from
1321 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1322 sequence is met. Before the error was not set so it would be unknown.
1324 Adjust yaz-marcdump MARC reader so that it skips until record separator
1327 --- 2.1.52 2007/03/07
1329 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1330 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1331 fd_set structure used as a bitmask for the FDs to be selected on.
1333 Using ACX_PTHREAD macro to check for POSIX threads.
1335 Fixed have-vsnprintf check.
1337 --- 2.1.50 2007/02/23
1339 Fixes for configure on BSD. Bug #900.
1341 Added snprintf/vsnprintf wrappers for systems that don't have
1342 limits (heavens forbid).
1344 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1345 created before all previous tasks were completed and removed from the
1346 task queue, the new task could be removed by a mistake.
1348 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1350 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1352 Fixed bug #832: Problem with MARC/charset in yaz-client.
1354 Fixed bug #668: save command line history for yaz-client.
1356 Fixed bug #830: pkg-config support.
1358 --- 2.1.48 2007/01/23
1360 Extended ZOOM result set options with two options that may be read by
1361 a client: resultSetStatus and presentStatus with values as specified for
1363 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1365 Fixed bug #827: Using SSL fails on Debian etch.
1367 Fixed bug #826: Weird looking chars for set of MARC records.
1369 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1370 that is treated as an ItemOrder with itemRequest being an XML document
1371 external. The value of "doc" is the content.
1373 Extended the GFS search facility. New member of bend_search_rr
1374 'estimated_hit_count' signals that hits is known to be an estmate
1375 (higher or lower than real hit count). New member 'partial_resultset'
1376 signals that the search was partial (hit count is lower or equal than
1377 real hit count). For Z39.50, the information is stored in resultSetStatus
1378 member of SearchResponse APDU. For SRU, the information is signalled
1379 via SRU diagnostic 59: "Result set created with valid partial results
1382 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1384 --- 2.1.46 2007/01/13
1386 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1388 Added ZOOM_connection_peek_event.
1390 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1391 the following new functions:
1392 ZOOM_event_nonblock, ZOOM_connection_process,
1393 ZOOM_connection_get_{socket,mask,timeout},
1394 ZOOM_connection_fire_event_{timeout,socket}.
1395 The existing blocking event handler, ZOOM_event, is a wrapper for the
1396 + blocking ZOOM_event_sys_{poll,select}.
1398 Implemented function ccl_xml_config which parses XML version of CCL
1399 configuration (bug #798).
1401 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1403 Added timings utility (yaz/timing.h)
1405 --- 2.1.44 2007/01/03
1407 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1410 Fixed bug #779: Rotation of apdu.log fails.
1412 Fixed for character set conversions:
1413 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1414 Honor G1 set in MARC-8 decoding.
1416 --- 2.1.42 2006/12/17
1418 Fixed bug #775: char conversion does not handle Alternative UTF-8
1421 Implemented function yaz_marc_read_line which parses MARC line format
1422 records. There is a wealth of formats out there. So far, this function
1423 reads line records produced by yaz_marc_write_line.
1425 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1426 more generic and easier to remember(!) options: -i format and -o format
1427 which specifies input format and output format respectively - where
1428 format is one of "marc", "marcxml", "line", "marcxchange".
1430 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1431 does not print anything except warnings for records.
1433 For yaz-marcdump, added support for MARC split into files (-s) with a given
1436 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1437 spec, at http://www.loc.gov/standards/sru/record-update/
1438 This has changed the binary layout of the following structs:
1439 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1440 bend_update_rr . Patch by Ko van der Sloot.
1442 Added GFS utility function bend_assoc_is_alive which returns 1 if
1443 association is still alive (client is connected); 0 otherwise (client
1444 closed connection). This allows busy servers to stop working for
1447 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1448 been a separate piece of software. This version of ziffy has been modified
1449 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1451 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1453 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1454 Client code may now interrogate options such as "init_opt_sort" to
1455 find out whether the server claims to support various options.
1457 --- 2.1.40 2006/11/27
1459 Added utilities yaz_{set,get}_esn to set/get element set name from
1462 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1463 of YAZ and has been so since YAZ 2.1.10.
1465 Implemented ZOOM_record_error which returns error information for
1466 record (surrogate diagnostic).
1468 --- 2.1.38 2006/10/31
1470 Updates for SRU Update by Ko van der Sloot:
1471 1. Changed name from "operation" to "action"
1472 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1473 versions in the code, marked as 'backward compatible'.
1474 3. Added diagnostics for SRU Update.
1476 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1478 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1480 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1482 For GFS, fixed problem with SRU diagnostic 'First record position out of
1483 range' being issued for 0 hits.
1485 zoomtst10 part of Windows Build.
1487 --- 2.1.36 2006/10/13
1489 Implemented yaz_filepath_comp which splits a path into file path
1490 components (required by Zebra 2.0.3+).
1492 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1493 BSD inspired license until now so this should not have any real impact on
1494 anybody. See http://www.opensource.org/licenses/bsd-license.php
1496 Fixed bug #687: Missing log lines.
1498 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1501 Fixed bug #689: SRU diagnostics to be added.
1503 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1504 whether a connection is idle (no more work do do).
1506 --- 2.1.34 2006/10/04
1508 Change type of optval from long to int for invocation of setsockopt with
1509 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1511 Added support for specifying the max log file size for the Generic
1512 Frontend Server. The size is given with option -r.
1514 --- 2.1.32 2006/09/21
1516 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1518 --- 2.1.30 2006/09/17
1520 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1523 Fixed bug in Generic Frontend Server that could cause a server to stop
1524 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1526 For the generic frontend server, the maximum record size is used as maximum
1527 size of incoming packages (SRU + Z39.50). The value until was previously
1528 only used in Z39.50 Init negotiation and, later, in a session controlled
1529 sizes of records returned. This is controlled using -k option. It can be
1530 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1532 --- 2.1.28 2006/09/04
1534 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1537 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1539 New option for yaz-marcdump -lpos=value which allows setting a portion
1540 of MARC header to a certain value.
1542 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1544 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1545 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1547 --- 2.1.26 2006/08/15
1549 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1552 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1554 --- 2.1.24 2006/08/08
1556 Fixed MARC ISO2709 encoding routines to deal with character set
1559 Minor changes to GFS logging. Database included in search request log
1562 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1563 cached/multiple records.
1565 Shared libraries are built by default on Unix+configure.
1567 Changed cql2pqf transformation to use a different evaluation order. The
1568 new order is: always, relation, structure, position, truncation, index
1569 and relationModifier. Old order was: always, relation, relationModifier,
1570 structure, index, position, truncation. Note that the the latter ones
1571 override former ones for identical attributes.. The new scheme means that
1572 it is possible to override any existing attribute with a relationModifier.
1573 And also that it is possible to override everything for the index rule
1574 (except the ones listed in relationModifier). No order is perfect but this
1575 one, we believe, covers more real cases.. The "always" should have been
1576 called "default", since the attributes there can be overridden with all
1579 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1580 compilation phase, but also for yaz-config --cflags output. This allows
1581 us to have public headers with Libxml2 stuff in them . It should also,
1582 eventually, make Libxml2 checks redundant in packages using YAZ, such
1585 --- 2.1.22 2006/06/15
1587 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1588 stored in uri, message and details.. Previously diagnostics were stored
1589 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1590 compatibility.. but he's probably the only one affected, so.
1592 Added support for CCL, compiled on the client side, in ZOOM-C. This
1593 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1594 input; the resulting query objects can be used for for searching with
1595 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1597 YAZ' configure searches for OpenSSL by default.
1599 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1600 SL_CTX_use_certificate_file. See
1601 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1602 for more info. Thanks to Ko van der Sloot.
1604 --- 2.1.20 2006/06/02
1606 Bug #600: SRU GET, POST support for yaz-client. Introduced
1607 command 'sru' which selects method SOAP/GET/POST.
1609 Allow missingValueAction to be specified for the sortspec string -
1610 function yaz_sort_spec. By default, the missing value action is null.
1611 Use ! to specify "abort". Use = followed by stringvalue to specify default
1614 Ensured that Present-handler (if defined) is called in GFS before any call to
1615 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1616 searchRetrieve requests.
1618 Documentation for YAZ is now based on the Docbook XML/XSLT using
1619 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1620 is no longer depending on jade/openjade or docbook-to-man scripts.
1621 PDF is no longer part of the distribution - but can optionally be
1622 made using DSSSL/jadetex or FOP.
1624 Added retrieval handling support in Generic Frontend Server to support
1625 conversion between MARC/XML as well as XSLTtransforms. See
1626 etc/yazgfs.xml for an example.
1628 Added Authentication support to Generic Frontend Server in SRU
1629 mode. Authentication using HTTP Basic is supported, as is the use
1630 of 'x-username' and 'x-password' parameters in the request itself.
1632 Added support for a new character set MARC8s identical to MARC8 except
1633 that it converts combined characters to single Unicode characters in the
1634 Latin-1 range (when possible).
1636 --- 2.1.18 2006/04/24
1638 ASN.1 compiler 0.4: generates brief Doxygen file header for
1639 generated .h/.c files.
1641 Utility yaz_iconv now supports conversion to MARC-8.
1643 New facilities for the MARC module. The reading - and writing of
1644 content are separate methods for the yaz_marc_t handle. The following
1645 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1646 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1647 format). Write functions have prefix yaz_marc_write_.. The existing
1648 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1649 available. Removed support for OAI-MARC and simplexml (not the
1650 simplexml from PHP5).
1652 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1653 to be returned for this connection.
1655 --- 2.1.16 2006/03/31
1657 Allow multiple languages and charsets to be specified with
1658 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1659 negcharset iso-8859-1,utf-8
1661 Translation of proximity nodes from CQL into PQF now works.
1663 Moved to automake 1.8, 1.9.
1665 Added function yaz_log_set_handler which allows a log handler to be
1666 installed. This handler will be called for all log messages. Output
1667 to file is also produced; but that can be disabled by passing NULL
1668 fname to yaz_log_init_file.
1670 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1672 For SRW (including GFS), accept application/soap+xml as content-type
1675 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1676 produces NO stylesheet reference even if a default stylesheet is specified
1679 --- 2.1.14 2006/03/14
1681 Updated Windows package to include yazd.dll + yazd.lib for the
1682 Development component.
1684 If the environment variable YAZ_LOG is set, then it is used as a
1685 string indicating the default level of logging to use if not
1686 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1687 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1688 used as before. So, for example, to omit warnings from YAZ logging,
1689 export YAZ_LOG=-warn
1691 cql_transform() now map structure and other attributes before indexes,
1692 so that index-specific structures and other attributes can override
1693 defaults. So now a combination of mapping specifications such as:
1695 index.dc.date = 1=date-modified 4=5
1696 does the right thing.
1698 cql_transform() now also respects the "always" mapping specification,
1699 which establishes an initial set of attributes to be used for all
1700 terms except where overridden by more specific attributes associated
1701 with the index, relation or modifier.
1703 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1704 which mode to use; one of "post", "get" or "soap" (SRW, default).
1706 Fixes for yaz_iconv routines: changed trie-based character set conversions
1707 to use only non-negative values for bit fields due to Sun's C compiler not
1708 supporting negative values.
1710 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1711 sequences where not read correctly. Fix by Rustam Usmanov.
1713 Updated win/makefile to use options, settings which makes things
1714 compile with VS C 2005.
1716 --- 2.1.12 2006/02/01
1718 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1720 In ZOOM socket code, use select instead of poll on MacOSX.
1722 ZOOM-C now support client-side compilation of CQL into RPN that is
1723 sent to the server, enabling CQL to be used against all Z39.50
1724 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1725 ZOOM_query object, and submit it using ZOOM_connection_search().
1726 The CQL-to-RPN translation uses a configuration file, the name of
1727 which must be specified in the Connection's "cqlfile" option.
1729 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1730 function, which takes as its start-term parameter a ZOOM_query object
1731 (which may have had either CQL or RPN set into it).
1734 --- 2.1.10 2005/11/29
1736 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1737 GFS to support this as well. Backend handler, bend_srw_update, does the
1738 update work. Code contributed by Ko van der Sloot.
1740 Allow retrieval of Search Result-1 information in ZOOM by the use of
1741 options that are attached to a result set. ZOOM documentation updated
1744 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1745 UTF-8 conversion. Patch by Raj Patel.
1747 Added option -m to GFS to control formatting of timestamps in log file.
1749 Added 'exit' as synonym for 'quit' in yaz-client
1751 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1752 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1753 for the new members. Patch by Ko van der Sloot.
1755 Added support for SRU POST. It is supported for content-type
1756 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1758 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1759 Instead make the library libyaz.la multi-threaded. Threading as a whole
1760 can still be disabled by configure option --disable-threads. Previosly,
1761 with older GLIBCs there were problems with MT libs under Apache. This
1762 has now been fixed a long time ago.
1764 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1767 CQL module modified to be case insensitive for relations/indexes/operations.
1769 Fixed bug in CQL transform code: incorrect value relationModifieder
1772 Added 'show all' command for yaz-client which retrieves all results
1775 Added new yaz-client, xmles, which takes a (private) OID and
1776 a document to be sent as an extended service request.
1778 Describe new yaz-client commands wait_response and set_auto_wait.
1780 Increase TCP/IP listener backlog from 3 (which I am guessing was
1781 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1782 that the socket will queue as many incoming connections as it's able
1783 to handle ongoing connections. In other words, it will never now
1784 refuse a connection that it would be able to handle merely because
1785 it's not got around to accepting() enough of the pending connections
1786 yet. This is the behaviour anyway under Linux, where the listen()
1787 argument is ignored; but not under BSD and on systems such as
1788 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1789 YAZ-based servers should now be uniform across operating systems in
1792 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1793 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1794 This allows yaz-marcdump to read large MARC batches (>2 GB).
1796 Modified all YAZ source files - except the source which is auto-generated
1797 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1800 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1801 corresponding to the existing *_setl() function. These allow option
1802 values containing arbitrary valuues.
1804 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1805 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1806 except that it returns an indicator of whether or not the sort
1807 criterion was accepted (0 for OK, -1 for invalid).
1809 --- 2.1.8 2005/06/07
1811 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1812 MARC output rather than returning "new" buffer.
1814 yaz-client warns about unknown init options.
1816 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1818 --- 2.1.6 2005/05/24
1820 Added support for SRW sort in Generic Frontend Server. Patch
1821 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1822 sortKeys - or NULL if none is provided.
1824 Fixed bug #307: It was impossible to specify indefinite/no timeout
1825 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1828 Added support for multiple languages and charsets to be specified in
1829 ZOOM. Each charset/language is separated by a blank. If negotiation is
1830 in effect in init-response, Option
1831 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1832 Code based on patch by Vasiliy Osadchuk.
1834 Fixed bug #306: infinite recursion that occurred when calling
1835 yaz_log_level_init as the first call (before other log level or
1838 Fixed bug in scan handling in front end server: if preferred-Position-In-
1839 Response was non-present, a NULL pointer referece was performed.
1841 --- 2.1.4 2005/04/26
1843 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1844 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1845 now defined for all those error codes. So instead of putting 109 in
1846 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1847 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1849 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1852 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1854 Program yaz-client now exits and produces an error message if multiple
1855 Z39.50 servers are specified on the command line (none or one allowed
1858 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1861 --- 2.1.2 2005/03/16
1863 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1865 Fixed bug #272: Preserve spacing for CCL terms.
1867 --- 2.1.0 2005/03/14
1869 Added support for virtual hosts and multiple backend servers for
1870 the YAZ frontend server. The configution is XML based and
1871 support specificition of CQL to RPN mappings and explain information.
1872 See section "Virtual Hosts" in the YAZ manual.
1874 Extended OPAC display utility. OPAC display utility renders
1875 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1876 to supplement yaz_marc_decode_wrbuf.
1878 Fixed a bug in MARC decoder that could caused it to crash for some
1879 invalid MARC records. More diagnostics and warnings where added in
1880 XML output (warnings, etc are stored in comments).
1882 --- 2.0.34 2005/02/08
1884 Fixes for UNIX domain sockets. Bug #261.
1886 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1888 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1889 Added yaz_marc_subfield_str which defines subfield lead string which is
1890 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1891 yaz_marc_endline_str which defines end of fields string used in
1892 YAZ_MARC_LINE format. Default string is newline.
1894 Experimental support for MarcXChange. This format can be produced
1895 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1896 http://www.bs.dk/standards/MarcXchange.xsd
1898 Added yaz-client commands scansize that sets maximum number of
1899 entries to be returned by scan.
1901 --- 2.0.32 2005/01/11
1903 Added support for SRW scan in yaz-client and Generic Frontend Server.
1905 * Added whereInList member to SRW Scan Term.
1907 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1909 Fixed NMEM system to return aligned blocks on the smallest boundaries
1910 that are suitably aligned for all possible types on the particular
1911 architecture YAZ is being built for.
1913 --- 2.0.30 2005/01/04
1915 Fixed numerious warnings that was issued with newer versions of GCC.
1917 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1918 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1921 Make YAZ Generic Frontend Server slightly faster.
1923 Enhance (and reduce) logging for Generic Frontend Server.
1925 Revert YAZ log system so that it flushes every write operation
1926 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1928 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1929 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1930 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1931 will effectively disable old definitions.
1933 --- 2.0.28 2004/11/09
1935 Added yaz_log_time_format which specifies log format using
1938 Added yaz_log_module_level which returns mask for a module. Value
1939 is non-zero mask a if module is enabled; zero if disabled.
1941 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1942 in include/yaz/cql.h.
1944 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1946 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1948 Fixed bug #172: RPM builds does not enable SSL.
1950 Doxyfile.in part of dist. Doxyfile generated by configure.
1952 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1953 are given and the corresponding component does not exist.
1955 Extend CCL documentation in YAZ reference. Describe r=r.
1957 --- 2.0.26 2004/10/01
1959 Fixed MARC->MARCXML conversion to properly deal with
1960 fields, subfields, indicators having non-ASCII characters.
1962 Fixed MARC->MARCXML conversion so that ASCII control characters
1963 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1966 Added YAZ GFS support for conversion from Z39.50 surrogate
1967 diagnostics to SRW surrogate diagnostics.
1969 Bug fix: YAZ GFS did not return schema in explainResponse.
1971 --- 2.0.25 2004/09/30
1973 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1974 now converts recordSchema to elementSetName as well as schema URI.
1976 Fixed bug in COMSTACK that prevented HTTP request packages from being
1979 --- 2.0.24 2004/09/29
1981 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1982 does not require white-space before and after the dash in a range, e.g.
1983 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1986 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1987 due to new GCC removing "redundant" code.
1989 Added yaz-client commands scanpos and scanstep that sets preferred
1990 position and step-size for scan.
1992 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1994 Added CCL utility ccl_qual_buf which parses one or more CCL
1995 spec lines in a buffer.
1997 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1998 of name and value - ignoring empty lines and comments.
2000 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2002 Added odr_get_element_path which returns current element path for an
2003 ODR handle. This utility is useful in error handling or user-defined
2006 Added ODR_PRINT utility odr_set_stream which is is a more generic
2007 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2008 to a write function and pointer to close function. The close function - if
2009 non-NULL - will be called during odr_destroy.
2011 Fixed bug in CCL parser where truncation char was not removed from
2012 right side when truncation=both was in effect.
2014 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2017 --- 2.0.23 2004/08/11
2019 Fix buffer overrun in CQL parser when dealing with proximity (%).
2021 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2022 to UTF-8/UCS conversion is now only based on codetables.xml.
2024 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2026 --- 2.0.22 2004/08/06
2028 Add support for more "commit changes" in ZOOM (uses Extended Services).
2030 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2033 Yet another small fix for configure of SSL.
2035 --- 2.0.21 2004/05/14
2037 Fix SSL libs for configure when --with-openssl=DIR is given.
2039 --- 2.0.20 2004/05/10
2041 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2043 SSL comstack now uses yaz.pem certificate file on server side
2044 by default. Certificate filename can be configured by calling
2045 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2047 Fix bug regarding multiple calls to ZOOM_connection_connect.
2049 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2051 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2052 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2054 ZOOM now allows inspection of X509 peer certificate for verification.
2055 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2057 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2058 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2059 as "modular" but it simplifies things.
2061 Added cs_get_peer_certificate to that returns peer X509 PEM.
2063 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2064 NULL if SSL is unavailable.
2066 Documentation about MARC decoding tools.
2068 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2070 --- 2.0.19 2004/03/30
2072 Rename CHANGELOG to NEWS to follow GNU style packing.
2074 Fix bug with missing initialization of member in init_diagnostics.
2075 This bug affects threaded version of GFS server.
2077 --- 2.0.18 2004/03/20
2079 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2082 Ensure zlib.dll is packed with Windows install.
2084 --- 2.0.17 2004/03/17
2086 Fix encoding of xsd:string to use text instead of CDATA.
2088 Fix endless loop in CQL parser with unbalanced ".
2090 Use a more compact way to store MARC-8 conversion tables.
2092 --- 2.0.16 2004/03/16 Debian only
2094 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2097 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2102 --- 2.0.15 2004/03/01
2104 Another fix for decoding of XML packed records.
2106 --- 2.0.14 2004/02/25
2108 Fixes for Chunked encoding. White space not ignored after length spec.
2110 Update NS and use default NS for SRW diagnostic elements.
2112 --- 2.0.13 2004/02/23
2114 Implement ZOOM_resultset_cache_reset which resets record cache.
2116 Implement ZOOM_resultset_sort which sorts a result set.
2118 Implement chunked HTTP transfer.
2120 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2122 --- 2.0.12 2004/02/16
2124 Added member 'schema' to bend_explain_rr structure so that backend
2125 can specify explain record identifier. Defaults to Zeerex 2.0.
2127 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2129 --- 2.0.11 2004/02/16
2131 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2134 Added init command for yaz-client which sends "extra" init request.
2136 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2137 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2139 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2141 Make ZOOM error code for "invalid query".
2143 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2145 --- 2.0.10 2004/02/05
2147 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2150 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2152 Added option -p <file> to make Generic Frontend Server to write PID file.
2154 Added option -D to put Generic Frontend Server in background on its own.
2156 Make ZOOM C recognize option "password". If unset, "pass" is used
2157 (for backwards compatibility).
2159 Fixed a bug in Generic Frontend Server that could make it crash if a
2160 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2163 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2164 Must be issued before open, in order to be in effect.
2166 --- 2.0.9-6 2004/01/12 Debian/Windows
2168 Make the SRU server more picky WRT unknown params, etc.
2170 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2172 New YAZ client command, options, that sets Z39.50 options.
2174 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2175 options from a string of tokens (one token for each option bit).
2177 Update SRW diagnostic code messages.
2179 --- 2.0.9-5 2004/01/07 Debian/Windows
2181 Handle user defined stylesheet for SRW/SRU.
2183 --- 2.0.9-4 2004/01/06 Debian/Windows
2185 Fix bug in decoding of Content-Length.
2187 --- 2.0.9-3 2004/01/06 Debian/Windows
2189 Fix a bug with decoding of XML packed records.
2191 --- 2.0.9-2 2004/01/05 Debian only
2193 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2195 Fix bug in SRW/SRU diagnostics decoding.
2197 --- 2.0.9 2004/01/05
2199 Fixed bug in Generic Frontend Server which could drop records exceeding
2200 preferred message size. Reported and fixed by Irina Dijour.
2202 Fixed calculation of package size for structured records in Generic
2203 Frontend Server. Reported and fixed by Irina Dijour.
2205 Fixed namespace for SRW/SRU diagnostics.
2207 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2209 --- 2.0.8 2003/12/22
2211 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2212 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2215 CQL changes to reflect recent changes to the specification:
2216 * Documentation talks about context sets instead of index sets.
2217 * Documentation talks about indexes instead of qualifiers.
2218 * The CQL-to-PQF transformer's configuration file now uses
2219 "index.set.name = <attributes>" instead of the old form
2220 "qualifier.set.name = <attributes>". (Both forms are still
2221 understood but the latter is deprecated.)
2222 * CQL terms with no explicit index specified are now interpreted as
2223 cql.serverChoice instead of srw.serverChoice (which of course
2224 behaves exactly the same.)
2226 --- 2.0.7 2003/12/16
2228 MARC conversion can now generate ISO2709 output in another
2229 character set. yaz-marcdump uses this facility if you invoke it
2232 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2233 functions from there can be used from C++.
2235 --- 2.0.6 2003/12/04
2237 Frontend server now transfers memory from decoded packages to stream
2240 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2241 references to show up.
2243 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2244 the ZOOM Abstract API. The older names for the same options are still
2245 also supported for the benefit of old applications.
2247 ZOOM-C supports "implementationId" and "implementationVersion" options
2248 to go along with "implementationName". These allow the user code to
2249 specify identification strings to be sent to servers.
2250 Add OID for the new ExtLite attribute set.
2252 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2253 as requested/supplid by Ere Maijala <ere@atp.fi>
2255 For generic frontend server, reverse the order of
2256 "toolkit-supplied / application-supplied" strings sent as implementationId,
2257 Name and Version. Also, remove the spaces around the slash. This brings
2258 the GFS in line with the behaviour of ZOOM-C on the client side.
2260 Add function ZOOM_scanset_display_term.
2262 yaz-client shows scan displayTerm if present.
2264 Utility yaz-iconv is now installed by default along with the man page
2267 Extend configure check for OpenSSL to use pkg-config where available (such
2270 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2271 server to specify uid/gid/mask for socket using the format
2272 unix:[user=uid,][group=gid,][umask=mask,]file=path
2273 If file= is omitted the existing format is assumed, e.g.
2275 in which case the mask is 0666 (rw for everybody).
2277 Major restructure of YAZ source. All source in libyaz is in src directory.
2278 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2279 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2281 Added man page for utility yaz-marcdump (used to be called marcdump).
2282 yaz-marcdump is installed by 'make install'.
2284 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2285 of incoming package failed.
2287 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2289 Change prototype of odr_perror: add const to message string.
2291 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2293 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2294 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2295 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2296 DNS lookup. There should not be any compatibility problems with this
2297 assuming that blocking=1 or 0 is used.
2299 Fix bad reference in UNIX comstack in function cs_addrstr.
2301 Fix for compilation on AIX.
2303 The generic front-end server (server/seshigh.c) now supports returning
2304 Init diagnostics to the client in User-information-field, in
2305 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2308 --- 2.0.4 2003/09/04
2310 Allow any CQL relation (not just all,any,exact,scr).
2312 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2313 that features the same UI.
2315 Implemented command update0 in YAZ client which is equivalent to
2316 update but uses old of Ext Update ASN.1.
2318 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2319 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2320 Previously no OID was used for this info.
2322 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2323 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2324 returns 'malformed search term' otherwise.
2326 SortResponse member resultCount now set to NULL in sort handler of
2329 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2332 Add three new utility functions for translating OIDs between various
2333 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2334 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2335 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2336 char *oid_to_dotstring(const int *oid, char *oidbuf);
2337 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2339 Reverted modifications for ES Update definition for z_IU0Update
2340 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2341 is back to YAZ 2.0.2.
2343 String value attributes for CCL parser.
2345 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2346 which their FirstSearch server returns in Init responses, sometimes
2347 carrying useful diagnostic information when Init fails. This has the
2348 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2349 "z39.50/oclcui.asn", where its definition is somewhat different from
2350 what OCLC document on their web-site, as required to interoperate with
2353 Support for anonymous authentication in yaz-client. Use the command
2356 * Fix the OID of the Index Data-local "admin" Extended Service from
2357 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2358 the 1000, which indicates a locally-defined OID, was a mistake.
2360 --- 2.0.3 2003/06/20
2362 Fix CCL directive @case handling so that it affects string match for
2363 both CCL keywords and qualifiers.
2365 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2366 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2367 Decoder has been updated with ASN.1 changes as listed in
2368 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2369 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2370 z_IUUpdate, remains unchanged.
2372 ZOOM_record_get may now return a record in a specific character set.
2373 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2374 "from" is the character set of record as returned by target. "to" is
2375 the character set to be returned. If omitted, "to" is UTF-8.
2377 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2379 New ODR utility, odr_getelement, which returns name of element for
2380 which encoding/decoding failed.
2382 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2383 in cases where a required element was omitted.
2385 Bug fix: some MARC8 sequences were not converted.
2387 New ZOOM option "step" which specifies number of records to be
2388 retrieved in one chunk. Used in conjunction with "start" and "count".
2390 SRW support for yaz-client. Use scheme http: to use it, e.g.
2393 yaz-client no longer does (un)intelligent character set conversions
2394 by default. Can be enabled with charset and marc_charset commands.
2396 xmalloc trace fix for 64-bit systems such as DEC alpha.
2398 Solaris 2.6 compile fix.
2400 New function, cql_strerror() translates SRW error codes, as returned
2401 by cql_transform_error(), into human-readable English strings. Used
2402 in yaz-client diagnostics when appropriate.
2404 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2405 converts it into a type-1 query which is sent to the server. This
2406 makes CQL available for use with all Z-servers, as opposed to the tiny
2407 minority that can handle CQL queries themselves.
2409 --- 2.0.2 2003/04/28
2411 New Debian package layout similar to the Redhat Package layout.
2413 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2414 and search result respectively.
2416 --- 2.0.1 2003/04/25
2418 Redhat package is now several packages: libyaz (runtime libraries),
2419 libyaz-devel (development and documentation, and yaz (utility programs).
2420 Package spec file by Morten Bogeskov.
2422 New member 'schema' in struct bend_fetch_rr which the name of requested
2423 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2424 handler MAY set this to reflect the schema of the returned record.
2426 New member 'display_term' in struct scan_entry. GFS now sets member entries
2427 and allocates scan entries to be filled by user scan handler. In previous
2428 version, entries member was allocated by the scan handler. That still works,
2429 but the GFS will ignore member display_term - assuming it was NOT set by
2430 the handler. The fact that the GFS now allocates the entries both allows
2431 for new members and makes a scan handler easier to write.
2433 Fix CQL lex buffer overflow.
2435 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2436 SRU default recordPacking is string.
2438 SRU protocol support for frontend server.
2440 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2442 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2444 Added scan for the ZOOM shell (zoomsh).
2448 * String Identifers for Schemas (Amendment 5).
2449 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2450 Old definition for schema
2451 Odr_oid *schema; /* OPT */
2456 Z_InternationalString *uri;
2457 #define Z_Schema_oid 1
2458 #define Z_Schema_uri 2
2461 * resultCount parameter to Sort Response (Amendment 1).
2462 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2464 Support for SRW 1.0 over HTTP. This is an optional feature and
2465 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2468 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2469 on the same port. SRW SearchRetrieveRequests are mapped
2470 to bend_init,bend_search,bend_fetch,bend_close.
2472 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2474 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2475 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2477 ZOOM connections are SRW based if schem http is used for hostname
2478 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2479 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2481 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2482 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2483 distance=n, order=true/false, relation=le, prox unit=word. If
2484 n is omitted, distance 1 is used.
2486 Fixed problem with C compiler include path in wrong order.
2488 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2489 on Solaris. Patch from Ko van der Sloot.
2491 New MARC decode API. All new functions operate on a yaz_marc_t
2492 handle. The most important new functions are: yaz_marc_create,
2493 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2494 decode and destroy respectively. Decoder can produce formats
2495 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2496 include/yaz/marcdisp.h.
2498 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2499 to UTF-8, UCS-32, wchar_t or Latin-1.
2501 * Prototypes for yaz_iconv_-functions moved to separate header
2502 include/yaz/yaz-iconv.h.
2504 Make a few private functions 'static' in unix.c. This prevents
2505 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2507 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2508 are set when Init Response is received.
2510 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2511 but returns diagnostic set as well.
2513 New function yaz_strerror which is a portable wrapper for
2514 strerror/strerror_r/GetLastMessage.
2516 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2517 is returned for MARC. If type is "oai", then OAI MARC is returned.
2519 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2522 --- 1.9.2 2002/11/26
2524 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2526 Fix bad race conditions on SIGTERM and terminate gracefully in
2529 Move retrieval (data1) module to Zebra since nobody seems to be
2532 Add GRS-1 render for ZOOM using same format as yaz-client.
2534 --- 1.9.1 2002/10/05
2536 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2538 Fix broken ESpec handling in data1 module.
2540 SGML reader parses comments and makes them part of the data1 tree.
2542 Added several type casts so that YAZ compiles as C++ code.
2544 ZOOM didn't handle PDU encoding failures properly.
2546 Added more Bib-1 diagnostics (approved extensions).
2548 GNU configure: better check for iconv.
2550 More portable use of accept, getpeername. Check for socklen_t. Use
2551 int/size_t if socklen_t is not defined.
2555 PQF parser rejects bad queries - including those with extra
2556 characters in them. PQF parser used to silently ignore that.
2557 Cleaner API for PQF added, which allows you to get detailed
2558 error information for bad queries (see yaz/pquery.h).
2560 Fixed bug in ZOOM_record_get for type "database".
2562 Implemented mini iconv library supporting conversions between
2563 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2565 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2567 --- 1.8.9 2002/08/20
2569 Fixed ZOOM C record cache so that preferredRecordSyntax and
2570 elementSetName is used to check for already fetched records.
2572 --- 1.8.8 2002/08/02
2574 Added three members in bend_initrequest structure to facilitate
2575 character set negotiation.
2577 Fixed a bug in frontend server that could cause indefinite
2578 loops under rare conditions.
2580 Revised character set utilities (charneg.h) so that encoding
2581 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2583 For PQF, directive @term <type> sets term type for Scan/Search.
2584 Here <type> is general, string, numeric, null. The term type
2585 is inherited - just like @attr.
2587 New call odr_set_charset that sets character set conversion for
2588 international-strings on a ODR stream. Prototype is:
2589 int odr_set_charset(ODR o, const char *to, const char *from);
2590 The InternationalString is still represented as C string in YAZ
2591 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2592 won't). On the protocol level, you can use any encoding.
2594 Support for UNIX sockets in ZOOM.
2596 Solaris recv sometimes returns errno == ENOENT. It is treated as
2597 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2599 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2600 both client and server. Code by Morten Bogeskov.
2602 --- 1.8.7 2002/05/22
2604 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2605 that they can be used directly from Visual Basic. You must recompile
2606 your windows APP if you're using ZOOM.
2608 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2609 Commands "lang" and "charset" sets language and character set respectively.
2610 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2611 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2613 Attributes from multiple CCL fields may be OR'ed rather than merged
2614 using directive "@field or". Fields are still merged by default -
2615 equivalent to "@field merge".
2617 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2620 Fixed bug in zget for parameter ExtendedServicesResponse.
2624 --- 1.8.6 2002/03/25
2626 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2628 Client displays USR.1:SearchResult-1 (hits per term).
2630 Additional Search Info for search in Generic Frontend Server.
2632 Fixed CCL parsing of "field=s".
2634 WIN32 installer - using the excellent NSIS software from nullsoft.
2636 Fixed CCL parsing of "field = - <number>".
2638 Added function yaz_marc_decode that decodes MARC for line mode
2639 display or XML (similar to that used by JZKit).
2641 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2642 Z39.50. But ISO/ILL was, however.
2644 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2645 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2648 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2650 --- 1.8.5 2002/02/03
2652 New YAZ client features: Command completion and new commands:
2653 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2654 Code provided by Jacob Poulsen.
2656 New call oid_trav, that visits all registered OIDs via callback.
2658 Function ZOOM_record_get now returns const char pointer rather than
2659 void pointer. It saves a lot of type casts.
2661 For YAZ client, command "auth" now allows you to set authentication
2662 in IdPass style. It is enabled when three tokens are given - order
2663 is user, group and password.
2665 Fix memory leaks in MARC record handling for ZOOM.
2667 New option for YAZ client, -k <kilobytes> that sets
2668 maximum record size. Similar to -k option for generic frontend
2669 server and yaz-ztest.
2671 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2673 Prefix query parser reports "fail" when bad attribute set is given.
2675 Fix in MARC decoder. Proximity logging. Fix for attribute set
2676 in scan handler for server. Patches by Shigeru Ishida.
2678 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2681 Configure option --with-openssl=<dir> now works when a directory is
2682 specified. Patch provided by Morten Bogeskov.
2684 New option for YAZ client, -u <auth>, that sets authentication.
2686 ZOOM fix: error information was sometimes "missing", since error
2687 was cleared/reset too when it shouldn't.
2689 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2691 --- 1.8.4 2002/01/04
2693 Scan for ZOOM API. New object ZOOM_scanset. New functions
2694 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2695 ZOOM_scanset_destroy.
2697 New ZOOM function, ZOOM_connection_last_event, that returns type
2698 of last event (such as "receive data", "send data", "apdu received",
2701 New ZOOM option, schema, that specifies schema for retrieval.
2703 New CCL feature. Qualifiers can be aliases for one or more
2704 other qualifiers (if more than one is given, OR is used).
2706 ZOOM uses named result sets if target supports it.
2708 Two new YAZ client commands: . (dot, which sources a script of YAZ
2709 client commands), and ! (to execute shell command.). Implemented
2712 Working on Debian packages.
2714 --- 1.8.3 2001/11/19
2716 YAZ client enables named result sets only if target supports it.
2718 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2720 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2721 with key="host" to get same result.
2723 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2724 Function Z3950_resultset_record(s) returns references to records
2725 "owned" by resultset. To become owner use Z3950_record_clone.
2727 Function z_ext_record handles Extended Services. Thanks to
2730 --- 1.8.2 2001/11/12
2732 CCL Parser fix: ignore token comma when dealing with and-lists.
2734 Documentation updates for COMSTACK.
2736 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2737 Changed prototype Z3950_records. For some functions, int parameters
2738 were changed to size_t.
2740 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2743 New MARC decode/display function, marc_display_exl, which properly rejects
2744 non-ISO2709 records. YAZ client uses it.
2746 --- 1.8.1 2001/10/29
2748 Fix bug: local attribute set wasn't set correctly in PQF strings.
2752 * Old Z39.50 codecs no longer supported.
2754 Added ZOOM C binding. See http://zoom.z3950.org/
2756 Renamed states for COMSTACKs to avoid confusion with events.
2758 Implemented cs_look and proper cs_rcvconnect.
2760 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2762 Configure detects POSIX threads on OpenBSD.
2764 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2765 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2767 When error is returned from present handler, non-surrogate diagnostic
2768 is returned in present response (and fetch handler is no longer called).
2770 * Minor adjustments to pquery parser (PQF). Token characters may be
2771 escaped by using backslash (C-style).
2773 PQF parser allows string attribute values to be specified. For @attr,
2774 non-numeric characters after the equal-sign are treated as strings
2775 (e.g. @attr 9=title).
2777 CCL trunction character may be defined (@truncation in file)
2779 * function zget_ExtendedServicesRequest sets waitAction to
2780 waitIfPossible (was wait).
2782 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2785 CCL operator names may be set in field definition files (CCL_bibset).
2786 See ccl/bib1 for an example.
2788 Fixes in ASN.1 compiler for C++ compatibility.
2790 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2791 and "op_or" to avoid conflict with C++.
2793 Fixed problem with GNU readline detection on Redhat 7.0.
2795 Added step-size for Scan backend handler.
2797 Fixed bug that made the frontend server crash when no attribute
2798 set was specified for scan.
2800 Front-end server automatically switches to original working directory
2801 when installed as an NT service. Previously -w had to be specified to
2804 Added extended attributes for retrieval module (data1), so that data1
2805 records carry d1_readXML/SGML attributes. d1_read also supports
2806 null-data rules ( <tag/>)
2808 On UNIX when POSIX threads are available, a separate library libyazthread
2809 is created. Programmers should link with that library and the yaz library
2810 when using threads. The reason for the split was that some applications
2811 on Linux, such as Apache, doesn't work well when using shared objects that
2814 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2815 (or any frontend server) in SSL mode by specifying ssl: followed by
2816 address. Only tested on UNIX.
2818 Added feature for CCL module. Virtual structure s=al or s=ol generates
2819 and-list and or-list respectively instead of phrase search.
2823 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2824 log_mask_str. This was done to avoid name conflicts with other libraries
2825 (such as other PHP extensions).
2827 Added raw OID member for preferred record syntax (request_format_raw)
2828 and returned record syntax (output_format_raw) for backend fetch method.
2830 Config file yaz-config now accepts options so that it returns specific
2831 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2833 Shared library support for UNIX using GNU libtool.
2835 * Modified backend interface. Request/Response struct's replaced by
2836 one read/write C struct. For example bend_fetchrequest and
2837 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2838 Every handler - even search has to be registered in bend_init
2839 handler. This means that the YAZ library no longer refers to
2840 external functions and it makes it possible to make the whole
2841 thing a single DLL/SO.
2843 Added Segment handler for backend server.
2845 Added Zmbol/Zebra administrative functions to YAZ client.
2847 Threaded frontend server on UNIX (when POSIX Threads are available).
2848 Starting the server with option -T enables multi-threading.
2852 Added configure option --enable-comp/disable-comp to control use
2853 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2854 located in sub directory asn.
2856 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2857 in ${exec_prefix}/bin along with the other programs yaz-client and
2860 GNU automake used to maintain makefiles.
2862 Added several OID's.
2864 Changed retrieval module so that we can load records with no abstract
2865 syntax defined. Tagpaths in these records are fully composed of string
2868 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2872 On UNIX, the generated makefile now supports a proper 'make install'.
2873 The prefix can be set via GNU configure to set the install location
2874 (default is /usr/local).
2876 * YAZ programs client and ztest were renamed to yaz-client and
2877 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2878 locations, such as /usr/bin,/usr/local/bin,etc.
2880 * YAZ Header files were moved from include to include/yaz. YAZ Header
2881 files are referred to as include <yaz/log.h> rather than <log.h>.
2882 The YAZ include path (-I ..) is therefore the same as before. Programmers
2883 should update their #include statements or use -Ipath/include/yaz
2884 instead. The main motivation for doing this change is that YAZ header files
2885 can be installed in "standard" locations /usr/include,/usr/local/include
2886 without introducing conflicts, since ALL YAZ header files are stored
2887 in subdirectory yaz (under /usr/include for example).
2889 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2890 rather than project/workspace files. We switched because project files
2891 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2894 Changed name of logging function, logf, to yaz_log, to prevent name
2895 clash with some math-log functions. The YAZ header log.h defines logf
2896 to yaz_log (#define) so there should be no incompatibilities by this
2899 Added bend_start/bend_stop handlers for server. These handler are
2900 called on start/stop of server. For windows they are called whenever
2901 a service is started/stopped.
2903 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2904 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2905 in util/yc.tcl. The auto-generated C code structures are, in a few
2906 cases, incompatible with the old decoders. There are differences in the
2907 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2908 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2909 The preprocessor variable ASN_COMPILED is defined when the compiled
2910 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2911 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2912 wish to use the old encoders/decoders you can specify --disable-yc
2915 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2916 version so that it supports both new - and old version of DB Update
2918 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2919 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2920 change. The name parameter can be set to 0 in which no name is specified
2921 for the construction. The macros odr_implicit and odr_explicit sets name
2922 parameter to zero for the construction involved. New macros
2923 odr_implicit_tag and odr_explicit_tag are similar to the others,
2924 except that a name parameter is added. For programmers' that don't use
2925 ODR they probably only need to change the call to z_APDU and z_External.
2927 Added access control facility by interfacing the TCP wrapper library.
2928 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2929 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2930 name of the daemon and enables the access control as specified in
2931 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2933 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2934 den Dool <H.M.vdnDool@kub.nl>.
2936 Added reference ID parameter to most functions in server API - refer
2937 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2939 Changed name of ccl library to libccl.a (was ccl.a).
2941 Fixed bug in decoder for Explain (Category TargetInfo).
2943 Added support for GNU readline in client. Thanks to Jacob Poulsen
2944 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2946 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2947 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2948 IMPLEMENTATION! This change was made to the development version before
2949 the ZIG decided to retract the amendment. If any users MUST be
2950 compatible with the original Update definition, PLEASE CONTACT US, and
2951 we will include a separate definition corresponding to the old Update
2952 ES. Note that because of the change to the ASN.1 of the
2953 TaskPackageRecordStructure we cannot define a single structure that
2954 will support both versions.
2956 * Added const modifier to buffer parameter for some ODR/BER encoding
2957 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2958 completeWAIS, odr_dumpBER.
2960 Fixed bug in client.c which caused a crash when a scanResponse didn't
2961 contain positionOfTerm.
2963 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2964 * will cause an error in a client if a non-YAZ target sends both a
2965 * list of Scan entries and non-surrogate diagnostics.
2967 Retrieval module enhancements. Tag sets may be typed in the reference
2968 to it. From the .abs-file the "tagset" directive takes a third optional
2969 integer type for the tag set referenced. From a .tag-file the "include"
2970 directive takes a third optional type as well. The old "type" directive
2971 in the tag set itself is still recognized but acts as the default type
2974 Backend interface change. Individual Scan terms returned from bend_scan
2975 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2976 in include/backend.h.
2978 Retrieval module enhancements. Multiple tag sets and attribute sets may
2979 be specified in abstract syntax specs. Revised the error/warning for
2980 logging messages reported by the retrieval module when reading the
2983 Object Identifier system (oid_..) changed. The API is backwards
2984 compatible but the oid-routines now allocates new OID's when needed.
2985 Raw OID's may be specified in oid_getvalbyname.
2987 YAZ now uses GNU configure to generate Makefile(s).
2989 * Minor changes in some of the member names of DeleteResultSetRequest and
2990 DeleteResultSetResponse. See include/proto.h.
2992 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2993 and added member 'languages' in TargetInfo (which was missing).
2995 Changed the way attribute sets are handled in the retrieval
2996 module. These are now cached, just like the abstract syntaxes
2999 Changed YAZ so that it links with compiled ASN.1.
3001 Added Explain-schema definitions and mapping routines. The following
3002 Explain categories have been implemented: AttributeDetails,
3003 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3005 Fixed minor bug in Windows version of Server Library.
3007 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3009 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3011 Added EXTERNAL: UNIverse Resource Report (non-standard).
3013 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3014 ENUMERATED and SET OF.
3016 * Added 'const' to some of the char pointer arguments for the
3017 functions, data1_read_node, data1_getelementbytagname,
3018 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3021 Fixed bug in data1_insert_taggeddata - the last_child member of
3022 parent wasn't initialised.
3024 * Changed data1_read_record and data1_read_node so that the supplied
3025 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3026 doesn't refer to any parts of the "SGML"-buffer.
3028 Fixed bug in server library (Windows version of statserv_remove).
3030 * Changed code so that it compiles as C++. The type definition
3031 of Odr_fun which is a member of Odr_arm was changed. The result is,
3032 that an explicit typecast is needed for the fun pointer when
3033 using Odr_arm - as in:
3034 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3036 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3038 Implemented the new structured date and time definition as approved
3039 by the ZIG. Added schemaId element to the specificTag in Espec-1
3040 (also approved at the last ZIG). Thanks to RVDM.
3042 Added some Object identifiers (RVDM).
3044 Changed the Update Extended Service (RVDM).
3046 Added command "refid" to client which specifies referenceId for
3047 the following requests.
3049 Implemented extended service handling for server. See ztest.c
3050 for an example as well as backend.h. New handlers are registerd
3051 in the Init handler.
3053 * Changed interface for sort in server.
3055 Added new members to statserv_options_block. It allows a server
3056 to read options from another source than just the command line. Thanks
3057 to Charles Woodfield.
3059 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3060 renamed to zboolean. Some C++ compilers complained about the name.
3062 Minor changes to gils.abs. Added index 's' (sort) on title
3063 and date/time-last-modified.
3065 --- 1.4pl2 1998/1/30
3067 Fixed bug in server library regarding inetd mode (-i). This bug
3068 was introduced by release 1.4.
3070 --- 1.4pl1 1998/1/29
3072 Added sort facility in client and backend server interface.
3074 Fixed problem with dependencies in Makefile(s).
3076 Fixed bugs for encoders/decoders of extended services and
3079 Implemented sub-tree feature for schemas. Sub-trees are
3080 referenced in *.abs-files. See explain.abs for an example
3081 of the use of this feature.
3083 Modified bib1.att; local attributes for ANY didn't include
3084 ANY itself (only affects use of the retrieval module).
3086 Fixed bug in plain SGML reader in function data1_read_node:
3087 tags with prefix "var" was incorrectly interpreted as variants.
3089 Added feature "sub-schemas" to enable references to - and definitions
3090 of - group of elements.
3092 * Removed member parent from type data1_element (in data1.h).
3094 Implemented function odr_nullval() that returns the value of
3097 * Removed member num_children from data1_node (in data1.h).
3099 Made NT service interface part of the server library. The
3100 function statserv_main uses the NT service when required and
3101 calls the statserv_start / statserv_close routines.
3103 Routine zget_SearchRequest and zget_PresentRequest fills
3104 resultSetName/Id member with "default" instead of "Default".
3106 Fixed memory leak in server. Request queue member wasn't freed.
3108 Fixed nmem_exit so that memory is freed.
3112 Revised the CCL parser utility to be thread safe.
3114 Added function, oid_ent_to_oid, to replace the function
3115 oid_getoidbyent, which is not thread safe.
3117 * Added nmem_init and nmem_exit to initialize and release
3118 NMEM resources. Function nmem_init should be called once in the
3119 initial thread before NMEM/ODR is used. statserv.c and client.c
3120 have been changed accordingly. The change was necessary to make
3121 NMEM thread safe. The NMEM memory pool is shared amongst threads
3122 in a process. Unix-based applications will still work fine without
3125 Added NT Services interface for the the Z39.50 (statserv) Server.
3126 Refer to the ztest.c source on the usage.
3128 Windows 95/NT port using MSVC5.0. Project files are included in the
3131 * Defined new 'global' handle for the retrieval (data1) system. The
3132 new handled, data1_handle, describes the state of the data1 system.
3133 This handle is passed as first argument to virtually all
3134 data1 related routines. The functions data1_create and data1_destroy
3135 creates and destroys a data1 handle respectively.
3137 Added ODR encode stream member to all backend request structures
3138 init, search, scan etc. This stream should be used to allocate all
3139 memory used for the response when thread safe operation is needed.
3141 Changed the comstack utility, cs_addstr, to be thread safe. The
3142 returned hostname string returned by the function is now part the
3145 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3146 function. The cs_straddr takes a COMSTACK handle as argument, so this
3147 function must be used after cs_create and before bind/connect.
3148 This function is thread safe.
3150 Moved test server to 'ztest' directory - generic server code still
3151 in 'server' directory.
3153 Made prefix query (pquery.c) utility thread safe.
3155 Added new function modifier YAZ_EXPORT to 'export' public DLL
3156 functions when using windows (see include/yconfig.h).
3158 Added definitions to the OID database (util/oid.c) (RVDM).
3160 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3162 Added call to ccl_rpn_delete in client program.
3164 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3165 release of RPN structure.
3167 Added support for C++, headers uses extern "C" for public definitions.
3168 With input from RVDM.
3170 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3171 Thanks to Ronald van der Meer (RVDM).
3173 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3175 Added support for private extensions to the OID database
3176 (oid_setprivateoids()). Thanks to RVDM.
3178 Added optional, physical ANY (key replication)
3180 Fixed null-reference problem in GRS-1 output filter.
3182 Proximity operator added to Prefix Query Format (PQF).
3184 In test client command "base" accepts multiple databases.
3186 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3190 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3192 Smallish bug-fixes in the new encoders/decoders (explain).
3194 Bug fixed in DeleteRequest.
3196 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3198 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3200 Added SOIF syntax (using private OID for now) to retrieval module and client.
3202 Added Update extended service.
3204 Added SearchResult-1 additional info structure.
3206 Added optional CCL (ISO8777) interpreter as separate module. Available
3209 --- 1.2 1996/6/10 (1st anniversary release)
3211 Added Summary record syntax. Lightly tested.
3213 Added OPAC record syntax. Untested.
3215 Added ResourceReport service encoders/decoders. Untested.
3217 Fixed bug in z_Unit - wrong tagging on unitSystem.
3219 Fixed bug in the DiagRecs decoder.
3221 Added options for max PDU size and session timeout to frontend-server.
3223 Added documentation of query-language parsers and other supporting utilities.
3225 [frontend-server] Added Attribute set to the bend_scanrequest API.
3227 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3228 surrogate diagnostics were generated.
3230 [retrieval] Allow multiple local values for attribute.
3232 [retrieval] Allow multiple attributes per element in .abs files. index type.
3234 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3236 --- 1.1pl2 1996/4/10
3238 Minor changes, mostly specific to Zebra's requirements (retrieval)
3242 Repaired bug in frontend server when running multiple listening
3243 endpoints in dynamic mode.
3245 z_External() now won't break if a known, ASN.1 value comes encapsulated
3246 in an octet-string. The value will pass through unmodified in an Odr_oct.
3248 Added a bit of code to the demo client to decode & display
3249 ASN.1-structured records represented in the octet-aligned branch of
3250 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3252 Added z_ext_getentbyref() to the ASN module. Doc updated.
3254 * Completed the SCAN definition in the ASN module. This may break SCAN
3255 code based on older YAZ-versions at compile-time. The fix is easy -
3258 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3259 under the SCAN definition. Remember to initialize this, server-people.
3261 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3262 that this does not extend to ODR and ASN.
3264 Comstack allows insertion of established socket (primarily for
3265 inetd-operation of servers). Doc updated.
3267 Front-end server can now start from the inetd in TCP mode. Doc
3270 --- 1.0pl4 1996/1/24
3274 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3275 the rank and record number.
3277 Adjustments to the frontend server.
3279 Fixed diagnostic BER dumper. It ignored the file argument.
3283 Various changes to retrieval module.
3285 Changed the union discriminators of the protocol files from enums to
3286 ints paired with #defines.
3288 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3291 *Changed operator in the RPN structure to 'roperator', again to avoid a
3294 Fixed problems in Explain decoders/encoders.
3296 --- 1.0pl2 1995/12/6
3298 Memory bug in log module fixed.
3300 --- 1.0pl1 1995/12/5
3302 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3304 Bug in Explain DatabaseInfo module fixed.
3306 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3310 The shift to v1.0 signals that we now consider the *core* functionality
3311 of YAZ reasonably stable (the core being more or less equivalent to
3312 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3313 tested (Explain not at all - though that will happen soonish).
3315 Minor changes to code to support Windows port.
3317 Various minor changes after we're getting to use GRS-1 & co. more.
3319 Added Espec-1 format.
3321 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3322 of the protocol and it cannot be selected when encoding (maps into 'string'
3323 when decoding). Needed to talk to some servers.
3325 Demo client can request simple element set names.
3327 Added Diagnostic Format encoders/decoders.
3329 Added simple Close handling to frontend server (no hooks for resource
3330 reporting yet), and demonstration client.
3332 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3334 --- 1.0b3 1995/08/24
3336 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3337 handled incorrectly when records were requested in the searchResponse. This
3338 will only affect you if you use the frontend-server.
3340 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3341 Test-client will ask for and print GRS1. Ztest will return dummy records
3344 Added Explain encoders/decoders to the service-level API. Untested.
3346 Added Extended Services: Item Order encoders and decoders to the Service-
3347 level API. Untested. We could use a recent copy of the pertinent bits
3348 of the ILL protocol to add those bits.
3350 Added diagnostic format 1 encoders/decoders to the service-level API.
3353 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3354 odr_cons.c, which causes a more correct output.
3356 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3357 was always set to 0 when no records were requested in the searchRequest.
3359 * Added better external-handling. This shouldn't harm old code that
3360 *encodes* externals. It can break code that looks for a
3361 'single-ASN1-type' representation, since those types that are known
3362 are now decoded immediately. Look at the SUTRS sample code in
3363 seshigh.c and client.c. Documentation updated.
3365 Handling of structured records in bend_fetchresponse. Length -1 marks
3366 structured record, type is deduced from format field.
3368 --- 1.0b2 1995/06/27
3369 Fairly quick maintenance release to add SUTRS support.
3371 Fixed handling of SUTRS records in the demonstration client.
3373 * Added format field to the bend_fetchrequest and bend_fetchresponce
3374 structures of the backend API (frontend server). When the record is
3375 returned, the value of the format field is mapped to an OID. The
3376 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3377 of the record. The special value VAL_NONE in the bend_request means
3378 that no specific format was requested by the client. Documentation
3379 updated accordingly. Test server (ztest) will return a fixed dummy
3380 SUTRS record if your client requests SUTRS.
3382 Documentation updated accordingly.
3384 You can now set external libraries and RANLIB support in the top-level
3388 First public release.
