1 New GFS search member: present_number. This is a hint to the
2 search handler how many records are going to be fetched immediately
3 following search. There's no guarantee that it's going to be the case,
4 since it depends on hit count (for Z39.50 piggyback) and whether errors
7 Make a few functions static (private). The functions getbyte_stream,
8 ungetbyte_stream and yaz_gets are now private. They were never declared
11 yaz-marcdump: exit(5) for serious decoding errors
13 ISO2709 decoding: be more picky WRT header
15 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
16 was only used as to indicate that next-result-set-position should be
18 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
19 Based on patch from Ashley Sanders.
21 Make some functions static/private in PQF parsing. Those functions were
22 never declared in a public header and so should not be in use by
23 applications based on YAZ.
27 ZOOM: special options to control APDU logging.
28 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
29 logging of APDUs until "saveAPDU" option is set again. If logging is
30 already enabled the effect is that current APDU buffer is cleared.
31 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
32 logging (default behavior on new connection).
33 The APDUs sent/received can be obtained by using
34 Using ZOOM_connection_option_get(c, "APDU") or
35 ZOOM_connection_option_getl(c, "APDU", &l).
37 GFS: relay implementation_version from backend
38 From 3.0.40 and later, implementation_version from backend was
39 not used in init response at all.
43 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
44 mode at all. Probably never did.
46 Make a new version of ztest.pem that, at least, is not expired.
50 Fix description of CCL directive 'case'.
52 More tight checking of form arguments (yaz_uri_to_array). Makes
53 YAZ better at rejecting big and/or bad POSTs.
55 SRU decoding does not report more than up to 10 invalid arguments.
57 rpn2cql: less quotes in generated terms. Semantics unchanged, but
58 it's prettier this way.
62 New utility yaz_decode_init_diag. Defined in proto.h.
64 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
65 given for unix local socket.
66 The COMSTACK string for doing so is:
69 unix:/myfile:tcp:localhost:9999/mybase
70 unix:/myfile:localhost:9999/mybase
71 unix:/myfile:http://fakehost/mybase
73 debian: Use dpkg-buildflags in build process.
77 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
78 global's SRU service uses a recordPosition scheme starting from zero.
79 First record's position should be one
80 according to the standard.
84 Allow more namespaces for SRU. This is to allow, for example, an
85 incorrect namespace returned from server
86 http://services.igi-global.com/sru .
88 Minor fixes for compilation on Windows.
92 daemon: log total number of bad signals from child on stop so that it
93 is more easy to spot problems with child worker processes.
95 retrieval: empty backend name attribute omits element set
96 from being used in retrieval.
100 Implement Solr sort strategy "solr", similar to sru11 sorting.
101 This will implement the correct parameters on Solr requst to do
104 --- 4.2.39 2012/09/28
106 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
109 MARC: Extra/missing indicator handled for MARCXML.
110 The indicator length is given in header and is the same for the
111 whole record. If attributes ind1, ind2 are missing, then content
112 character defaults to blank. Extra indicator attributes (beyond)
113 indicator length are treated as an error.
115 Reformat: delete trailing whitespace
117 --- 4.2.38 2012/09/17
119 MARC: fix non-ASCII characters for leader. This is to ensure we can
120 generate XML in UTF-8.
122 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
123 in one node with structure word.
125 --- 4.2.37 2012/09/04
127 yaz-json-parse: JSON output may be pretty printed by using option
130 Increase default value of max message for Z39.50 Init for GFS, ZOOM
131 and yaz-client. Old value was 1 MB. New value is 64 MB.
133 --- 4.2.36 2012/08/22
135 yaz-client: don't display bogus records from SRU servers. Some SRU servers
136 return more records than given by *maximumRecords*. Skipping those in
139 record_render: simplify buffer return handling and fix at least one bad
140 memory reference, that broke the test_embed_record sometimes.
142 Allow http://user:pass@host notation for yaz_url_exec.
144 zoomsh: allow shell command to be executed. Via the system(3) call.
146 yaz_poll: Allow num_fds == 0
148 yaz-client: fix bad encoding of "itemorder item". The itemorder
149 item <no> - command forgot to use length of encoded Item Request
150 package. Error present since YAZ 3.
152 yaz-ztest: fix bad usage of session handle. Bug was introduced when
153 result sets were saved (271a9c83).
155 SRU recordPacking: guess record packing in response rather than looking
156 at the recordPacking element which, OF COURSE, changed semantics in SRU
159 Decode SRU 2.0 responses. The official namespace for responses, according
160 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
161 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
162 nature.com's server, however, usee namespace
163 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
164 we are now using a glob-expr to match up the namespace. ZOOM C and
165 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
166 I can not find a single real example showing the "real" namespace in
167 the documentation from OASIS. The namespace for requests is different
168 from responses, but this is not added to YAZ yet, when we don't encode
171 --- 4.2.35 2012/06/26
173 zoom/record_render: add support for Base64 decoding fo MARC records
174 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
175 which will decode base64 + ISO2709 marc-8 encoded material from text node
178 --- 4.2.34 2012/06/07
180 Add missing definitions ZOOM_resultset_get_facet_field_by_index
181 and ZOOM_resultset_facets_names.
183 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
186 Change APDU dump printing to avoid long leading blanks. For levels 16
187 or larger the level is shown and the indentation is truncated but
188 recursed with modula 8. This makes it still reasonable easy to read
189 - even for nested BER dumps.
191 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
192 return 0 (incomplete package) in case where the BER package was
193 considered too nested (return value of -2).
195 dumpber: lines of level 15 are not indented further. Two spaces per
196 indentation; indentation 15 or more is indented to a fixed indentation
197 and augmented with a level=<no> indication.
199 zoomsh: increase max size of command+args
201 GFS: No limit in RPN buf size in CQL to RPN conversion.
203 --- 4.2.33 2012/05/09
205 New function for daemon utility, yaz_daemon_stop .
207 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
209 --- 4.2.32 2012/04/25
211 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
212 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
214 --- 4.2.31 2012/04/23
216 YAZ daemon utility relays SIGUSR1 to child process.
218 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
219 would result in en empty database list - which in turn would result in
220 encoding failure for search.
222 Fix reading beyond string in yaz_sort_spec.
224 --- 4.2.30 2012/04/11
226 Add two new SRU diagnostics:
227 236: Access to specified database denied
228 1015: Init/AC: Maximum number of simultaneous sessions for Userid
230 Document the very useful ZOOM-C option "apdulog".
232 CQL to RPN: term may be passed through verbatim. This is enabled with
233 truncation.cql . The assumption being that the term is already CQL.
235 --- 4.2.29 2012/03/20
237 record_conv: leader spec may be given for marc element.
238 The leader spec is given as attribute leaderspec for element marc.
239 For example to convert a MARC21 record from MARC-8 to UTF-8:
240 <marc inputformat="marc" outputformat="marc"
241 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
243 record_conv: allow user-XSLT params. For example:
244 <xslt stylesheet="MARC21slim2DC.xsl">
245 <param name="myparameter" value="myvalue"/>
246 <param name="otherparameter" value="othervalue"/>
249 record_conv: fix error handling for missing marc charsets.
251 CQL: fix extra terms in wrong order.
253 --- 4.2.28 2012/03/06
255 record_conv: modify new API for conversion types. The conversion types
256 may be passed in new functions yaz_record_conv_configure_t and
257 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
259 Avoid mixed statement/variable declare; fixes compilation with Visual
262 --- 4.2.27 2012/02/28
264 Add non-standard SRU diagnostic: 235: "Database does not exist".
265 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
266 Update SRU to Bib-1 diagnostic maps accordingly.
268 CCL: add two new diagnostics for unsupported masking. The new
269 diagnostics are: "Embedded truncation not supported" and
270 "Single charcacter mask not supported".
272 --- 4.2.26 2012/02/23
274 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
276 --- 4.2.25 2012/01/11
278 Build YAZ for Ubuntu Oneiric.
280 CCL: allow parantheses for proximity operands. For example CCL query
281 (a) % (b) is now allowed.
283 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
284 marked dead, rather then being destroyed. If not, the session memory is
285 being free'd before the search/scan handler is finished. Also destroy
286 'request' memory in request_release rather than in various places,
287 which resulted in leaks from time to time.
289 --- 4.2.24 2011/12/21
291 cql_sortby_to_sortkeys: honor sort prefix.
293 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
294 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
295 The rpn2cql family of functions now always returns quoted CQL terms.
297 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
299 --- 4.2.23 2011/12/15
301 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
302 sequence is treated as one. For example, &&a=b&&&c& is identical to
305 --- 4.2.22 2011/12/05
307 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
308 APDUs for a connection to a WRBUF.
310 --- 4.2.21 2011/11/23
312 Fix cql_sortby_to_sortkeys. Completely broken before.
314 Make CCL's @truncation work again.
316 --- 4.2.20 2011/11/09
318 New ZOOM connection setting: tproxy. It's like proxy, but does not
319 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
320 to set resolved address + port for a connection outside ZOOM itself.
322 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
324 --- 4.2.19 2011/11/07
326 Fix uninitialized variable in Solr spell support (could cause SEGV
327 for SRU response decoding).
329 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
330 back-end's addinfo through into the ZOOM response addinfo.
332 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
333 they are separated by a colon and a space rather than simply
336 --- 4.2.18 2011/10/28
338 Add support for Solr spell-checking/suggestions through ZOOM.
339 If a Solr target has been configured correctly for spelling-checking
340 and suggestions, these will now be returned on the ResultSet option
341 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
343 --- 4.2.17 2011/09/28
345 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
346 with a flag whether to substitute escape sequences or not.
348 --- 4.2.16 2011/09/22
350 Fix nmem_strsplit_escape to substitute escape char properly.
352 New option for zoomsh -e , which makes it abort on first error and
353 return process exit code to indicate success/failure.
355 YAZ options utility supports special option -- which makes all it treat
356 all following arguments as non-options.
358 --- 4.2.15 2011/09/16
360 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
361 searched if absolute filename is given.
363 Fix conv_xslt() error-reporting when stylesheet is not found.
364 (The value of fullpath is meaningless in this situation.)
366 --- 4.2.14 2011/09/07
368 Fix problem in CQL sort node creation: un-initialized memory.
370 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
371 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
372 CQL sortby depending on whether Type-1 or CQL is actually sent to the
375 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
376 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
378 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
379 will make it possible to use both single-character mask (#) and wildcard (?)
380 in CCL . Throw diagnostic for left truncation because that is not supported
383 --- 4.2.13 2011/09/01
385 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
386 cases using escapes (\-sequences) and masking.
388 PQF parse fix: A trailing backslash followed by end-of-string (\0)
389 would result in a read one byte beyond string.
391 rpn2ccl may use Z39.50 masking for terms (t=z).
393 ICU check fix. Don't include library -lCrun on Solaris, unless present.
395 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
396 not --cppflags (which seeems like an error in icu-config).
398 --- 4.2.12 2011/08/27 RPM package only
400 cql2ccl: fix conversion of terms: operator characters were not
403 --- 4.2.11 2011/08/25 RPM package only
405 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
406 CCL parser will map both # and ? to their regular expression
407 quivalents (. and .*).
409 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
410 of reserved CQL characters.
412 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
413 is, so that they are passed through.
415 --- 4.2.10 2011/08/24
417 ZOOM SRU mode: more aggressive re-connect.
419 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
420 made available as a utility function, declared in <yaz/logrpn.h>
422 rpn2cql_structure() supports proximity nodes (except that the Type-1
423 proximity node's "exclusion" binary is ignored, as there is no way to
424 express that in CQL). Fixes bug #4564.
428 Fix SEGV that could occur if set command of zoomsh was given without
429 value (2nd argument).
431 Fix SEGV that could occur if unsupported transport was given for
432 COMSTACK - say https (when SSL was unavailable).
434 Build yaz-url on Windows too.
438 New utility to get web content. Header is url.h. A command line tool
439 yaz-url is part of the distribution and packages.
441 Fixes for SSL COMSTACK (when gnutls is in use).
443 New functions yaz_base64{encode,decode}. Header is base64.h.
447 ZOOM C includes HTTP response buffer as additional info if it fails
448 to decode the SRU response.
450 Make wrbuf_json_puts available.
454 zoom: throw diagnostic for invalid value for option "sru". Before a
455 bad SRU request was sent.
457 Adding new utility wrbuf_vp_puts.
459 Add cclxmlconfig.obj to win/makefile. It was missing completely.
463 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
464 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
465 redirect was used at the same time.
467 MARC line mode decoding: be less picky about length given - first
468 5 digits of header that is.
470 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
472 Changes to decoding of SRU records: a record with recordPacking=xml is
473 modified with a new root element <yaz_record> if the recordData contains
474 multiple children elements. This is to make the record XML parseable
477 RPN to SOLR conversion: encode special characters.
479 Generic Frontend Server: fix uinitialized member, stepSize.
483 Fix a bug in SRU decoding of records.. The database records stored
484 had un-initialized memory, but it would only be seen with yaz_record_render
485 and type_spec="ext" .
487 Fix a bug in ccl_qual_dup introduced in 4.2.3.
491 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
495 Add new utilities to convert from CQL to CCL . These utilities have
496 prefix cql_to_ccl defined in cql.h.
498 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
499 lead to memory heap corruptions when ICU utilities were in use.
503 Make compilation work without Libxml2.
505 yaz-client: remove redundant blanks in display of searchResult-1 term
510 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
511 resulting CQL node (tree) in a new node CQL_NODE_SORT.
513 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
514 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
515 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
516 Note that the CQL sortby spec is only converted when the GFS is already
517 converting from CQL to RPN (cql2rpn element).
519 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
520 specify whether to collapse delimitors or not. The existing nmem_strsplit
521 do collapse (collapse parameter = 1).
523 Windows installer: For NSIS, set InstallDir depending on x86/x64.
525 Rename internal func yaz_use_attribute_create. While non-static, this
526 function is not declared in a public header.
530 Add -lCrun when linking with ICU on Solaris.
532 More quicks character set conversions for OPAC records.
536 fix problem with record_render: records were converted (character set
537 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
541 SRU: add methods for handling DADS SRU-proxy facets.
543 Separate OPAC record character set for ZOOM_record. yaz_record_render
544 allows a character set given as charset=from/opacfrom,to where 'from' is
545 the character set of a bibliographic record, 'opacfrom' is character set
546 of OPAC record and 'to' is the target character set.
550 yaz-client: show may XML format records. Command show followed by 'format'
551 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
554 src/stemmer.c: Avoid using unnamed union. It is not supported by some
557 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
560 Update yaz.spec to operate on both SLES11 / Centos 5.5.
562 RPM: Release includes 'indexdata' name. Use indexdata in release name so
563 this package can be distinguished from other vendors.
565 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
566 as determined by configure
568 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
570 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
571 returns no error and no record, the present request is considered
572 partial (only a subset of the records could be returned by backend), and
573 so it is appropriate to set Present Status to partial-4.
577 Move yaz-config man pages to section 1.
579 More documentation about SOLR.
581 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
582 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
583 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
584 peers on some Linux systems. However, in general that does not work
585 so YAZ can not rely on that to work. Debian changed behavior in this
586 respect from Debian lenny to Debian squeeze (still testing as of Oct
588 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
590 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
594 Fix yaz-config output: echo_source not set correctly by configure.
598 SOLR WebService support for yaz-client and ZOOM.
600 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
602 --- 4.0.12 2010/08/17
604 Z39.50 facet support. Facet specifications are passed for search in
605 other-information with ASN.1 as defined in facet.asn and OID
606 .10.1000.81.5 . Facets are expressed as an Attribute list as known
607 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
608 3 is limit (number of entries to get in response). yaz-ztest returns
609 dummy facets if a client asks for them.
611 --- 4.0.11 2010/07/09
613 CCL fixes: bug 2895 and bug 3539.
615 GR1-display: add comma in display - was removed by mistake in
618 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
620 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
622 --- 4.0.10 2010/06/18
624 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
625 result set from a connection. The result set will be on its own
626 thereafter; no operations on it will perform retrievals from a target.
627 Only cached copies are returned.
629 ZOOM C:fix case for HTTP servers responding with Connection:close.
630 Ensure that if there is a current task it is resumed (like fetching
631 more records in a result set) . Bug #3484.
633 PQF parser: use odr_atoi for Odr_int (not atoi)
635 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
636 values that contain any non-digits are treated as string attributes
637 (previously decoding only checked for leading character ([0-9]). PQF
638 encoding: attribute string values are not surrounded by double-quotes.
642 New utility for managing threads - thread_create.h.
644 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
645 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
646 but YAZ' implementation do.
648 Fixes for yaz_cond-functions on Windows 7.
650 DLL export more symbols.
652 zoomsh: show record do NOT render opac.
654 Remove *.la files from Debian and RPM packages.
658 Debian package libyaz-dev depends on libgnutls-dev again (was
659 removed in YAZ 4.0.6, but due to Libtool it is still needed
660 even though yaz-config do not list libgnutls libs).
662 ZOOM: Use only one WRBUF for returning string results for
663 ZOOM_resultset. Reduces memory usage for ZOOM in general.
665 ZOOM: ZOOM_connection do not use a shared pointer to
666 ZOOM_resultset after ZOOM_resultset is destructed by
667 user. Reverts to YAZ 4.0.4 behavior.
671 record-conv: fix problem with at least one XSL conversion -
672 due to probably incorrect usage of XML XSL documents.
676 Fix yaz-config for static mode and the use of SSL (gnutls).
680 Forward decl timeval struct in mutex.h and gettimeofday.h.
682 yaz-config: fix 'static' mode linking.
686 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
687 are wrappers for pthreads or Windows. For Windows these are put in
688 a separate DLL: yaz_cond4.
690 libyaz.la (whole source) is compiled with thread. If thread support
691 is enabled enabled, all source of YAZ is compiled with treading support.
692 This allows core utilities such as yaz_log to use thread facilities.
693 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
694 thread utilities. This commit moves mutex utilities (mutex.c) from
695 libyaz_server.la to libyaz.la.
697 yaz-json-parse displays leading text until error.
701 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
702 patch from Giannis Kosmas.
704 SRU: no longer URL encode SRU database. The URL for an SRU server is
705 a URL and such is alreeady encoded - at least when given with leading
706 http:// or https://. This reverts behavior to YAZ 3.0.50.
708 Support for new MARC XML notation TurboMARC which like MARCXML is a
709 complete representation of MARC/ISO2709.. This one, however, is more
710 compact and allows for faster processing with XSLT. TurboMARC can be
711 used in the marcdisp.h API, from the yaz-marcdump utility and from
714 yaz-ztest can be configured - via the database - to perform certain
715 delays when it performs operations search, present and single record
716 fetch. This allows testers to make yaz-ztest act as a real or even slow
717 Z39.50 server. Refer to the yaz-ztest man pages for details.
721 wrbuf_destroy allows NULL WRBUF passed to it.
723 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
725 Add ZOOM_connection_close.
727 No fixed size buffers for ZOOM shell - bug #3257.
729 tstodr: make it work on s390 platform.
731 New icu iterator-functions. The new icu_iter-functions makes it possible
732 to use ICU chains from many threads.
734 yaz-client: better syntax check for show command.
738 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
741 New simple local-file XML include facility which allows file glob-patterns.
742 Refer to yaz/xml_include.h.
744 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
747 ZOOM_record_get supports new parameter "format" which makes it format XML
750 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
751 JSONText in ECMA-262) is JSONValue, not JSONObject.
755 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
756 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
758 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
759 POSIX/Unix builds .so with major version 4.
761 Remove old LOG_-defines from log.h. They have been obsolete and
762 undefined by default for the last 5 years.
764 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
766 GFS: Remove socket (int *fd) from search_rr handler. The socket
767 descriptor ptr is a facility that allowed a search handler to supply
768 a socket which would serve as a callback - when search was complete.
769 This facility has now been in use for years.
771 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
772 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
773 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
774 returns 'const char *' rather than 'char *. The returned string is
775 read-only and should not be modified by applications. COMSTACK cs_close is
776 now a void function - it no longer returns int. No applications check for
777 the value and the implementations has always returned 0.
779 ZOOM: use size_t for scan hit counts and str size. Functions
780 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
781 occ (hit count) and len (string length) are now of type size_t pointer
782 rather than int pointer. This is to be able to represent large hit counts
783 and to also just to use the proper type for string length (strlen result).
785 New JSON parser. Refer to include/yaz/json.h .
787 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
788 Used to be int in some cases. Many wrbuf_-functions used to return an int
789 indicating some length.. These return values were never used. And so they
792 ODR: odr_malloc, odr_total now takes size_t for size.
794 clone_z_type: fix leak; occurred for encoding failures.
796 --- 3.0.52 2009/12/03
798 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
799 bug was introduced in 3.0.51.
801 --- 3.0.51 2009/12/02
803 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
805 tcpip comstack: fix leak for getaddrinfo.
807 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
808 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
809 Decoding of SRU "path" database is performed by private function
810 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
811 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
813 yaz-client: honor base command for SRU. Change when database setting
814 is applied for SRU and ensure it is kept when a connection is reset.
815 Change also the way errors are displayed or SRU (decoding of packages).
817 --- 3.0.50 2009/11/02
819 Add support for extra request / response data for SRU codecs and GFS.
820 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
821 for extra data response buffer and length. For the GFS, both request
822 and response data (XML) is carried in extra_args and extra_response_data
823 for the search handler. Patch by Ko van der Sloot.
825 ZOOM: For queries that cannot be converted to the specified rpnCharset,
826 ZOOM now returns a diagnostic on the client-side ('invalid query' /
827 10010). This fixes bug #2113.
829 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
830 cmdfile included a 'quit' command that would result in a memory violation.
832 --- 3.0.49 2009/10/01
834 Make a number of functions defined in xmlquery.c static. These have
835 never been declared in a public header file (yaz/xmlquery.h) and was
836 made public by mistake.
838 Improve speed of character conversions (iconv utilities). This makes
839 conversions from MARC-8 faster.
841 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
842 unless type desired is "raw". This will prevent type "xml" from
843 returning ISO2709 .. Which obviously can not be XML parsed.
845 Fix memory leak in ZOOM that would occur if option apdulog was used
846 on a re-used connection.
848 Frontend server logs HTTP requests.
850 Frontend server now sends Z39.50 close when it times out (sesssion has
851 been idle for too long). Versions 2.0.30 and earlier also sent close.
852 But due to a mistake this was disabled in all versions after that, i.e.
853 the server would just close the socket immediately.
855 yaz-client emits a better message when receiving an unrecognised
856 userInformationField.
858 Skip zero-length subfields when decoding ISO2709. This rare case happens
859 if a record has two FS characters in a sequence. Without this patch
860 there would be a reference beyond char array in using_code_len fragments
863 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
865 --- 3.0.48 2009/08/28
867 The show command offered by the zoomsh command now takes a 3d optional
868 parameter type which is what is passed to ZOOM_record. If the type
869 argument is omitted, "render" is used.
871 RPN to CQL conv may use USE string attributes (bug #2978).
873 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
875 --- 3.0.47 2009/07/08
877 Function yaz_xml2query allows a diagnostic element in the PQF XML
878 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
879 code and additional info respectively.
881 The BER BOOLEAN is now the integral type Odr_bool which still happens
882 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
883 typedef'd to Odr_int. This is still an integral 'int', but it may be
884 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
885 ASN-1 compiler as well as programs has been updated to use the new types.
887 --- 3.0.46 2009/06/08
889 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
890 only the bibliographic record was rendered. For type=opac, an OPAC
891 record is only returned if it is present.
893 iconv: small fix for encoding of advancegreek.
895 yaz-client: avoid double display of SRU/SRW records (bug #2798).
897 yaz-client: option auto_reconnect=on really reconnects.
899 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
901 server: avoid null ptr ref for for yaz_poll errors.
903 build: fix RPM build for RHEL 5.3.
905 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
907 --- 3.0.45 2009/03/31
909 Fixed bug #2709: TCP connect returns Invalid argument.
911 Fixed compilation for mingw.
913 Honor charset for raw records (ZOOM_record_get).
915 Fixed use of errno for threaded mode that was seen on Solaris 10.
917 Fixed argument passing with blanks in value for Windows Service.
919 Disable YAZ' own log rotate by default (no 1 GB limit).
920 The variable l_max_size which specifies the log file limit is set to 0
921 (DISABLED): This is due to the fact that YAZ is most often deployed using
922 logrotate. Also YAZ can not perform log rotate because of unsufficient
923 permissions (setuid).
925 --- 3.0.44 2009/02/17
927 List supported encodings in man page for yaz-iconv.
929 Fixed missing SSL libs for --libs output
931 Re-established OID record syntax application-xml. Nobody should use it
932 but we don't want to change soname because of this symbol being absent.
934 --- 3.0.42 2009/02/02
936 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
938 Added member named_result_sets for init handler struct for the GFS. This
939 allows a server to disable named result sets.
941 Removed OID record syntax application-xml.
943 Added support for rule-based transliterator for ICU wrapper of YAZ.
945 Fixed bug #1902: yaz-icu XML output.
947 Make YAZ checks Emacs friendly.
949 BITSTRING value shows value. Bug #2346.
951 ISO2709 decoding: skip control characters from indicator data.
953 Omit sort key by default in yaz-icu's output.
955 Allow combined single char options (again) for YAZ' options function.
957 Utility yaz-marcdump got option to display YAZ version (-V).
959 Allow YAZ to use ICU 3.4.
961 Added new ICU test case which illustrates removal of diacritics.
963 --- 3.0.41 2008/12/29
965 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
967 --- 3.0.40 2008/12/29
969 For configure, using option --without-xml2 also disables Libxslt/Libexslt
972 Fixed bug #2352: yaz-marcdump crashes for certain record.
974 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
976 Added support for Danmarc2 to UTF-8 conversion.
978 Added support for ISO5426 to UTF-8 conversion.
980 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
981 implementation version.
983 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
985 --- 3.0.38 2008/11/10
987 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
988 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
990 ZOOM C now interprets databaseName option for ZOOM connection as path
993 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
995 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
997 Dummy Libxml2 types no longer defined in headers of YAZ'.
999 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1002 --- 3.0.36 2008/09/26
1004 Various ODR chapter fixes.
1006 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1008 Added missing source for Windows compilation, mutex.c.
1010 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1012 For SRU connections in ZOOM all records up to "count" are now fetched.
1014 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1015 in Windows due to bad error handling for Libxml2.
1017 Added facility for sending arbitrary records (ASN.1 any) using
1018 ZOOM C's Extended service update. Patch by Sam Reynolds.
1020 New options for ZOOM C's connection, logapdu which makes ZOOM log
1023 --- 3.0.34 2008/06/18
1025 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1027 --- 3.0.32 2008/06/12
1029 Fixed memory violation that could occur when decoding UTF-8. This bug
1030 was only present in 3.0.30 of YAZ.
1032 --- 3.0.30 2008/06/06
1034 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1035 GNU TLS is used by default (if found).
1037 yaz-ztest returns OPAC records if a client asks for OPAC.
1039 Improved speed of MARC-8 encoding.
1041 Added support for lossy and loss-less MARC-8 encoding.
1043 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1045 Added new Windows Service wrapper (sc).
1047 yaz-client's itemorder command may now send a file.
1049 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1051 Added new function yaz_log_xml_errors.
1053 Allow (but warn) unknown XML attributes in MARCXML parsing.
1055 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1057 The UTF-8 to MARC-8 conversion now uses a different set of characters
1058 for Greek symbols. Bug #2120.
1060 --- 3.0.26 2008/02/21
1062 Added yaz_daemon (daemon.h).
1064 Fixed bug #2068: pkg-config trouble
1066 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1068 --- 3.0.24 2008/01/28
1070 Document --with-xml2 option.
1072 Added OPAC XML XSD (etc/opacxml.xsd).
1074 Allow glob mask for name attribute in retrieval element for the
1075 generic frontend server's retrieval facility.
1077 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1078 except POLLIN/POLLOUT.
1080 Fixed error handling in cs_listen. Bug #2037.
1082 --- 3.0.22 2008/01/20
1084 Fixed version in yaz/yaz-version.h.
1086 Fixed bug #2027: Crash when closing connection.
1088 Changed configure so that ICU support is only enabled if only ICU
1089 and Libxml2 is available (because the ICU chain is XML based).
1091 --- 3.0.20 2008/01/15
1093 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1094 is built. Only this DLL depends on the ICU runtime.
1096 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1097 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1099 Changed license of CCL module to 'Revised BSD'. After consultation with
1100 remaining members of the original EUROPAGATE consortium, we are re-issuing
1101 the CCL module without a separate license. The software was developed by
1102 Index Data as part of a research project. The special license was included
1103 to help feed usage information back to the project consortium to support
1104 project evaluation. At this time, the project consortium has long-since
1105 disbanded, and the majority of the original principals have retired. At the
1106 same time, we have significantly modified the software during the following
1107 years, to the point where very practically no original code remains. To
1108 simplify re-use of the software, we have contacted those members of the
1109 consortium who could be reached, and agreed to re-issue the module as a
1110 proper part of the YAZ package.
1112 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1114 CQL closer to being version 1.2 compliant. CQL also allows free-form
1115 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1118 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1119 bug could make Extended services handling crash in the ZOOM layer. This
1120 bug was only present in YAZ 3.0.18.
1122 --- 3.0.18 2007/12/19
1124 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1127 yaz-marcdump reads and writes collection wrapped records.
1129 Handle OPAC for record conversion module.
1131 Fixes for ICU wrapper.
1133 Allow ICU libs to be controlled with --with-icu .
1135 --- 3.0.16 2007/11/12
1137 Added yaz_poll which is a wrapper for select/poll. When poll is available
1138 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1139 sockets to be in use.
1141 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1142 functionality through an XML based configuration (ICU chain). This system
1143 is useful for search facilities such as Pazpar2 and Zebra that needs to
1144 perform tokenization of indexed material. The ICU code in a separate
1145 library libyaz3_icu.a.
1147 Added HTTP tunnel facility for COMSTACK, bug #1752.
1148 This is a facility that allows a Web proxy, such as squid, to tunnel
1149 Z39.50 traffic. This facility is "transparent" to must applications
1150 using YAZ. It's enabled by using pseudo transport connect: followed by
1151 the proxy address, followed by command, then follwed by he regular
1152 "virtual" addresss. For example,
1153 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1155 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1157 --- 3.0.14 2007/09/21
1159 Fixed bad memory reference in ZOOM_record - cuased by member not being
1160 initialized. This was a problem only in YAZ 3.0.12.
1162 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1163 fields were not removed.
1165 Changed the way C code is generated from codetables.xml. Made a MARC-8
1166 conversion trie for each characterSet section rather than codeTable.
1167 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1168 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1170 --- 3.0.12 2007/09/12
1172 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1173 from ZOOM_record_error).
1175 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1177 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1179 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1181 Better SRW-to-Bib-1 diagnostic mapping.
1183 ZOOM C and yaz-client announces SRU version 1.2 by default.
1185 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1188 Fixed in yaz_sru_decode to allow other version than 1.1.
1190 --- 3.0.10 2007/08/22
1192 Added support for SRU scan for ZOOM.
1194 Added support for the use of the older versions or Extended Service
1195 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1196 set to the version , 1=first, 2=second, 3=third. The third version is
1197 what ZOOM C has used so far. And that, obviously, is the default.
1199 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1200 therefore in Zebra and in SimpleServer-based applications). The new
1201 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1202 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1203 which is passed into the back-end search callback function.
1205 Added support for HTTP Basic authentication in clients: the SRU/W
1206 codec encodes the username/password elements of the PDU structure
1207 appropriately, and these may be set using the "user" and "password"
1208 options in ZOOM-C applications (the same options that are used for
1209 Z39.50 authentication).
1211 --- 3.0.8 2007/06/25
1213 Fixed bug #1208: SSL appears to be broken in ZOOM.
1215 Fixed bug #1206: Libxml2 include path weirdness.
1217 Added oid_name_to_dotstring.
1219 Allow elementSetName to be specified for ZOOM C record update.
1221 Allow waitAction to be specified for ZOOM C based for Extended Services.
1223 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1224 syntax OID. Bug introduced in YAZ 3 series.
1226 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1228 --- 3.0.6 2007/06/06
1230 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1231 directory. yaz-client now reads commands from file given by option -f
1232 if specified; then tries to read .yazclientrc in current directory.
1233 Failing that, it reads .yazclientrc from user's home directory.
1235 Added support for correlationInfo Note and ID for Record Update via
1238 Added yaz-client command querycharset which specifies character set for
1239 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1240 (termListAndStartPoint).
1242 Charset ISO5428:1984 is an alias for ISO5428-1984.
1244 Implemented a way to perform scan in a result set using Z39.50. This
1245 is achieved by attaching the result set name in the characterInfo
1246 (type InternationalString) of OtherInformation in the Scan Request PDU.
1247 The result set is identified in the otherinformation by the new OID:
1248 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1249 This allows for scan in result set and faceted search . Zebra did some
1250 of this in the APT term using attribute type 8 and value being result
1251 set. Using the OtherInformation approach for this is cleaner and easier
1252 to work with in proxies and the like. This facility can be used in
1253 yaz-client using new command setscan which takes a result set as first
1254 argument, start position (APT) as second.
1256 Changed decoding of SRU XML packed records to deal with servers that
1257 have recordData with XML data with multiple root nodes. Also make
1258 comparison for recordPacking case insensitive. Again, one server
1259 returns "XML" where others return "xml".
1261 For SRU responses allow Content-Type application/xml as well as text/xml.
1263 --- 3.0.4 2007/05/21
1265 Fixed bug in character set conversion of BER strings. Bug introduced
1268 --- 3.0.2 2007/05/08
1270 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1272 For OID class, use oid_class consistently.
1274 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1277 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1278 character set for bibliographic information interchange". By Giannis Kosmas.
1280 Added documentation on new OID API.
1282 --- 3.0.0 2007/05/02
1284 Changes to generic frontend server interface: added new member
1285 'query_charset' for bend_initrequest structure. A backend init handler
1286 should set this member to its native character set for query terms.
1287 When defined, the frontend server logic will announce this character set
1288 to a client if the negotiationModel bit is set by the client. All server
1289 implementors are encouraged to specify this. If a backend server does not
1290 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1292 Added CCL utility to remove terms (stop words) from resulting RPN
1293 tree. This is handled by functions with prefix ccl_stop_words_ .
1295 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1296 terms in RPN queries.
1298 Clean-up the CCL API. Moved some internal structures from ccl.h to
1299 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1300 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1301 This is replaced by ccl_parser_find_str which takes a string instead.
1303 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1304 libyaz.la is the core of YAZ except the generic frontend server and
1305 does not depend on POSIX threads anymore. libyaz_server.la is the
1306 generic frontend server facilities and uses POSIX thread functionality
1307 if available. The libyaz.la no longer depends on POSIX threads because
1308 the number of global structures is limited. NMEM no longer re-uses blocks
1309 between threads ; it simply free's memory immediately but allocates in
1310 "large" chunks as usual. We don't expect any performance penalties
1311 because of this. The yaz_log system is still using a global log_level so
1312 caution must be taken when modifying it with yaz_log_init_.. +
1313 yaz_log_mask_str. This, however, should not cause any trouble because
1314 these functions are called during initialization of application code
1315 anyway. `yaz-config --libs server` returns libs for server applications;
1316 `yaz-config --libs` returns libs for non-server applications.
1318 New OID database - with public definitions in oid_db.h. Removed old OID
1319 database including the head oid.h and definitions such as enum oid_value
1320 and struct oident. The new OID database uses the same string names as
1321 before but the 'protocol' is gone. There are now only two representations
1322 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1323 converts from string to OID; functions with prefix yaz_oid_to_string
1324 converts the other way.
1326 Change to emit_term() in CQL-to-PQF query translation: when a term has
1327 the /regexp relation modifier, do not process it for leading and
1328 trailing "^" and "*", which have quite different meanings in regular
1331 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1332 write handlers no longer carries a 'last' parameter. This will make
1333 yaz_iconv flush "less" characters. A flush is performed by call to
1334 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1336 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1337 removed, because function yaz_query_to_wrbuf does the same.
1339 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1340 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1342 Deprecated MARC utility functions removed.
1344 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1347 Branch split: YAZ_2_1_55_branch
1349 --- 2.1.54 2007/03/16
1351 Fix to ZOOM-C so that transparent reconnection is properly handled on
1352 connections that are in asynchronous mode.
1354 Fixed compilation on OpenBSD 4.0.
1356 Large strings in GRS-1 records are now properly displayed in yaz-client.
1358 Added character conversion support for "advancegreek"; based on patch from
1361 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1362 sequence is met. Before the error was not set so it would be unknown.
1364 Adjust yaz-marcdump MARC reader so that it skips until record separator
1367 --- 2.1.52 2007/03/07
1369 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1370 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1371 fd_set structure used as a bitmask for the FDs to be selected on.
1373 Using ACX_PTHREAD macro to check for POSIX threads.
1375 Fixed have-vsnprintf check.
1377 --- 2.1.50 2007/02/23
1379 Fixes for configure on BSD. Bug #900.
1381 Added snprintf/vsnprintf wrappers for systems that don't have
1382 limits (heavens forbid).
1384 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1385 created before all previous tasks were completed and removed from the
1386 task queue, the new task could be removed by a mistake.
1388 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1390 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1392 Fixed bug #832: Problem with MARC/charset in yaz-client.
1394 Fixed bug #668: save command line history for yaz-client.
1396 Fixed bug #830: pkg-config support.
1398 --- 2.1.48 2007/01/23
1400 Extended ZOOM result set options with two options that may be read by
1401 a client: resultSetStatus and presentStatus with values as specified for
1403 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1405 Fixed bug #827: Using SSL fails on Debian etch.
1407 Fixed bug #826: Weird looking chars for set of MARC records.
1409 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1410 that is treated as an ItemOrder with itemRequest being an XML document
1411 external. The value of "doc" is the content.
1413 Extended the GFS search facility. New member of bend_search_rr
1414 'estimated_hit_count' signals that hits is known to be an estmate
1415 (higher or lower than real hit count). New member 'partial_resultset'
1416 signals that the search was partial (hit count is lower or equal than
1417 real hit count). For Z39.50, the information is stored in resultSetStatus
1418 member of SearchResponse APDU. For SRU, the information is signalled
1419 via SRU diagnostic 59: "Result set created with valid partial results
1422 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1424 --- 2.1.46 2007/01/13
1426 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1428 Added ZOOM_connection_peek_event.
1430 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1431 the following new functions:
1432 ZOOM_event_nonblock, ZOOM_connection_process,
1433 ZOOM_connection_get_{socket,mask,timeout},
1434 ZOOM_connection_fire_event_{timeout,socket}.
1435 The existing blocking event handler, ZOOM_event, is a wrapper for the
1436 + blocking ZOOM_event_sys_{poll,select}.
1438 Implemented function ccl_xml_config which parses XML version of CCL
1439 configuration (bug #798).
1441 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1443 Added timings utility (yaz/timing.h)
1445 --- 2.1.44 2007/01/03
1447 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1450 Fixed bug #779: Rotation of apdu.log fails.
1452 Fixed for character set conversions:
1453 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1454 Honor G1 set in MARC-8 decoding.
1456 --- 2.1.42 2006/12/17
1458 Fixed bug #775: char conversion does not handle Alternative UTF-8
1461 Implemented function yaz_marc_read_line which parses MARC line format
1462 records. There is a wealth of formats out there. So far, this function
1463 reads line records produced by yaz_marc_write_line.
1465 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1466 more generic and easier to remember(!) options: -i format and -o format
1467 which specifies input format and output format respectively - where
1468 format is one of "marc", "marcxml", "line", "marcxchange".
1470 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1471 does not print anything except warnings for records.
1473 For yaz-marcdump, added support for MARC split into files (-s) with a given
1476 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1477 spec, at http://www.loc.gov/standards/sru/record-update/
1478 This has changed the binary layout of the following structs:
1479 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1480 bend_update_rr . Patch by Ko van der Sloot.
1482 Added GFS utility function bend_assoc_is_alive which returns 1 if
1483 association is still alive (client is connected); 0 otherwise (client
1484 closed connection). This allows busy servers to stop working for
1487 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1488 been a separate piece of software. This version of ziffy has been modified
1489 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1491 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1493 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1494 Client code may now interrogate options such as "init_opt_sort" to
1495 find out whether the server claims to support various options.
1497 --- 2.1.40 2006/11/27
1499 Added utilities yaz_{set,get}_esn to set/get element set name from
1502 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1503 of YAZ and has been so since YAZ 2.1.10.
1505 Implemented ZOOM_record_error which returns error information for
1506 record (surrogate diagnostic).
1508 --- 2.1.38 2006/10/31
1510 Updates for SRU Update by Ko van der Sloot:
1511 1. Changed name from "operation" to "action"
1512 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1513 versions in the code, marked as 'backward compatible'.
1514 3. Added diagnostics for SRU Update.
1516 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1518 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1520 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1522 For GFS, fixed problem with SRU diagnostic 'First record position out of
1523 range' being issued for 0 hits.
1525 zoomtst10 part of Windows Build.
1527 --- 2.1.36 2006/10/13
1529 Implemented yaz_filepath_comp which splits a path into file path
1530 components (required by Zebra 2.0.3+).
1532 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1533 BSD inspired license until now so this should not have any real impact on
1534 anybody. See http://www.opensource.org/licenses/bsd-license.php
1536 Fixed bug #687: Missing log lines.
1538 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1541 Fixed bug #689: SRU diagnostics to be added.
1543 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1544 whether a connection is idle (no more work do do).
1546 --- 2.1.34 2006/10/04
1548 Change type of optval from long to int for invocation of setsockopt with
1549 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1551 Added support for specifying the max log file size for the Generic
1552 Frontend Server. The size is given with option -r.
1554 --- 2.1.32 2006/09/21
1556 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1558 --- 2.1.30 2006/09/17
1560 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1563 Fixed bug in Generic Frontend Server that could cause a server to stop
1564 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1566 For the generic frontend server, the maximum record size is used as maximum
1567 size of incoming packages (SRU + Z39.50). The value until was previously
1568 only used in Z39.50 Init negotiation and, later, in a session controlled
1569 sizes of records returned. This is controlled using -k option. It can be
1570 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1572 --- 2.1.28 2006/09/04
1574 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1577 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1579 New option for yaz-marcdump -lpos=value which allows setting a portion
1580 of MARC header to a certain value.
1582 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1584 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1585 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1587 --- 2.1.26 2006/08/15
1589 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1592 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1594 --- 2.1.24 2006/08/08
1596 Fixed MARC ISO2709 encoding routines to deal with character set
1599 Minor changes to GFS logging. Database included in search request log
1602 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1603 cached/multiple records.
1605 Shared libraries are built by default on Unix+configure.
1607 Changed cql2pqf transformation to use a different evaluation order. The
1608 new order is: always, relation, structure, position, truncation, index
1609 and relationModifier. Old order was: always, relation, relationModifier,
1610 structure, index, position, truncation. Note that the the latter ones
1611 override former ones for identical attributes.. The new scheme means that
1612 it is possible to override any existing attribute with a relationModifier.
1613 And also that it is possible to override everything for the index rule
1614 (except the ones listed in relationModifier). No order is perfect but this
1615 one, we believe, covers more real cases.. The "always" should have been
1616 called "default", since the attributes there can be overridden with all
1619 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1620 compilation phase, but also for yaz-config --cflags output. This allows
1621 us to have public headers with Libxml2 stuff in them . It should also,
1622 eventually, make Libxml2 checks redundant in packages using YAZ, such
1625 --- 2.1.22 2006/06/15
1627 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1628 stored in uri, message and details.. Previously diagnostics were stored
1629 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1630 compatibility.. but he's probably the only one affected, so.
1632 Added support for CCL, compiled on the client side, in ZOOM-C. This
1633 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1634 input; the resulting query objects can be used for for searching with
1635 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1637 YAZ' configure searches for OpenSSL by default.
1639 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1640 SL_CTX_use_certificate_file. See
1641 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1642 for more info. Thanks to Ko van der Sloot.
1644 --- 2.1.20 2006/06/02
1646 Bug #600: SRU GET, POST support for yaz-client. Introduced
1647 command 'sru' which selects method SOAP/GET/POST.
1649 Allow missingValueAction to be specified for the sortspec string -
1650 function yaz_sort_spec. By default, the missing value action is null.
1651 Use ! to specify "abort". Use = followed by stringvalue to specify default
1654 Ensured that Present-handler (if defined) is called in GFS before any call to
1655 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1656 searchRetrieve requests.
1658 Documentation for YAZ is now based on the Docbook XML/XSLT using
1659 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1660 is no longer depending on jade/openjade or docbook-to-man scripts.
1661 PDF is no longer part of the distribution - but can optionally be
1662 made using DSSSL/jadetex or FOP.
1664 Added retrieval handling support in Generic Frontend Server to support
1665 conversion between MARC/XML as well as XSLTtransforms. See
1666 etc/yazgfs.xml for an example.
1668 Added Authentication support to Generic Frontend Server in SRU
1669 mode. Authentication using HTTP Basic is supported, as is the use
1670 of 'x-username' and 'x-password' parameters in the request itself.
1672 Added support for a new character set MARC8s identical to MARC8 except
1673 that it converts combined characters to single Unicode characters in the
1674 Latin-1 range (when possible).
1676 --- 2.1.18 2006/04/24
1678 ASN.1 compiler 0.4: generates brief Doxygen file header for
1679 generated .h/.c files.
1681 Utility yaz_iconv now supports conversion to MARC-8.
1683 New facilities for the MARC module. The reading - and writing of
1684 content are separate methods for the yaz_marc_t handle. The following
1685 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1686 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1687 format). Write functions have prefix yaz_marc_write_.. The existing
1688 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1689 available. Removed support for OAI-MARC and simplexml (not the
1690 simplexml from PHP5).
1692 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1693 to be returned for this connection.
1695 --- 2.1.16 2006/03/31
1697 Allow multiple languages and charsets to be specified with
1698 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1699 negcharset iso-8859-1,utf-8
1701 Translation of proximity nodes from CQL into PQF now works.
1703 Moved to automake 1.8, 1.9.
1705 Added function yaz_log_set_handler which allows a log handler to be
1706 installed. This handler will be called for all log messages. Output
1707 to file is also produced; but that can be disabled by passing NULL
1708 fname to yaz_log_init_file.
1710 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1712 For SRW (including GFS), accept application/soap+xml as content-type
1715 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1716 produces NO stylesheet reference even if a default stylesheet is specified
1719 --- 2.1.14 2006/03/14
1721 Updated Windows package to include yazd.dll + yazd.lib for the
1722 Development component.
1724 If the environment variable YAZ_LOG is set, then it is used as a
1725 string indicating the default level of logging to use if not
1726 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1727 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1728 used as before. So, for example, to omit warnings from YAZ logging,
1729 export YAZ_LOG=-warn
1731 cql_transform() now map structure and other attributes before indexes,
1732 so that index-specific structures and other attributes can override
1733 defaults. So now a combination of mapping specifications such as:
1735 index.dc.date = 1=date-modified 4=5
1736 does the right thing.
1738 cql_transform() now also respects the "always" mapping specification,
1739 which establishes an initial set of attributes to be used for all
1740 terms except where overridden by more specific attributes associated
1741 with the index, relation or modifier.
1743 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1744 which mode to use; one of "post", "get" or "soap" (SRW, default).
1746 Fixes for yaz_iconv routines: changed trie-based character set conversions
1747 to use only non-negative values for bit fields due to Sun's C compiler not
1748 supporting negative values.
1750 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1751 sequences where not read correctly. Fix by Rustam Usmanov.
1753 Updated win/makefile to use options, settings which makes things
1754 compile with VS C 2005.
1756 --- 2.1.12 2006/02/01
1758 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1760 In ZOOM socket code, use select instead of poll on MacOSX.
1762 ZOOM-C now support client-side compilation of CQL into RPN that is
1763 sent to the server, enabling CQL to be used against all Z39.50
1764 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1765 ZOOM_query object, and submit it using ZOOM_connection_search().
1766 The CQL-to-RPN translation uses a configuration file, the name of
1767 which must be specified in the Connection's "cqlfile" option.
1769 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1770 function, which takes as its start-term parameter a ZOOM_query object
1771 (which may have had either CQL or RPN set into it).
1774 --- 2.1.10 2005/11/29
1776 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1777 GFS to support this as well. Backend handler, bend_srw_update, does the
1778 update work. Code contributed by Ko van der Sloot.
1780 Allow retrieval of Search Result-1 information in ZOOM by the use of
1781 options that are attached to a result set. ZOOM documentation updated
1784 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1785 UTF-8 conversion. Patch by Raj Patel.
1787 Added option -m to GFS to control formatting of timestamps in log file.
1789 Added 'exit' as synonym for 'quit' in yaz-client
1791 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1792 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1793 for the new members. Patch by Ko van der Sloot.
1795 Added support for SRU POST. It is supported for content-type
1796 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1798 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1799 Instead make the library libyaz.la multi-threaded. Threading as a whole
1800 can still be disabled by configure option --disable-threads. Previosly,
1801 with older GLIBCs there were problems with MT libs under Apache. This
1802 has now been fixed a long time ago.
1804 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1807 CQL module modified to be case insensitive for relations/indexes/operations.
1809 Fixed bug in CQL transform code: incorrect value relationModifieder
1812 Added 'show all' command for yaz-client which retrieves all results
1815 Added new yaz-client, xmles, which takes a (private) OID and
1816 a document to be sent as an extended service request.
1818 Describe new yaz-client commands wait_response and set_auto_wait.
1820 Increase TCP/IP listener backlog from 3 (which I am guessing was
1821 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1822 that the socket will queue as many incoming connections as it's able
1823 to handle ongoing connections. In other words, it will never now
1824 refuse a connection that it would be able to handle merely because
1825 it's not got around to accepting() enough of the pending connections
1826 yet. This is the behaviour anyway under Linux, where the listen()
1827 argument is ignored; but not under BSD and on systems such as
1828 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1829 YAZ-based servers should now be uniform across operating systems in
1832 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1833 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1834 This allows yaz-marcdump to read large MARC batches (>2 GB).
1836 Modified all YAZ source files - except the source which is auto-generated
1837 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1840 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1841 corresponding to the existing *_setl() function. These allow option
1842 values containing arbitrary valuues.
1844 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1845 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1846 except that it returns an indicator of whether or not the sort
1847 criterion was accepted (0 for OK, -1 for invalid).
1849 --- 2.1.8 2005/06/07
1851 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1852 MARC output rather than returning "new" buffer.
1854 yaz-client warns about unknown init options.
1856 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1858 --- 2.1.6 2005/05/24
1860 Added support for SRW sort in Generic Frontend Server. Patch
1861 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1862 sortKeys - or NULL if none is provided.
1864 Fixed bug #307: It was impossible to specify indefinite/no timeout
1865 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1868 Added support for multiple languages and charsets to be specified in
1869 ZOOM. Each charset/language is separated by a blank. If negotiation is
1870 in effect in init-response, Option
1871 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1872 Code based on patch by Vasiliy Osadchuk.
1874 Fixed bug #306: infinite recursion that occurred when calling
1875 yaz_log_level_init as the first call (before other log level or
1878 Fixed bug in scan handling in front end server: if preferred-Position-In-
1879 Response was non-present, a NULL pointer referece was performed.
1881 --- 2.1.4 2005/04/26
1883 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1884 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1885 now defined for all those error codes. So instead of putting 109 in
1886 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1887 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1889 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1892 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1894 Program yaz-client now exits and produces an error message if multiple
1895 Z39.50 servers are specified on the command line (none or one allowed
1898 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1901 --- 2.1.2 2005/03/16
1903 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1905 Fixed bug #272: Preserve spacing for CCL terms.
1907 --- 2.1.0 2005/03/14
1909 Added support for virtual hosts and multiple backend servers for
1910 the YAZ frontend server. The configution is XML based and
1911 support specificition of CQL to RPN mappings and explain information.
1912 See section "Virtual Hosts" in the YAZ manual.
1914 Extended OPAC display utility. OPAC display utility renders
1915 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1916 to supplement yaz_marc_decode_wrbuf.
1918 Fixed a bug in MARC decoder that could caused it to crash for some
1919 invalid MARC records. More diagnostics and warnings where added in
1920 XML output (warnings, etc are stored in comments).
1922 --- 2.0.34 2005/02/08
1924 Fixes for UNIX domain sockets. Bug #261.
1926 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1928 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1929 Added yaz_marc_subfield_str which defines subfield lead string which is
1930 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1931 yaz_marc_endline_str which defines end of fields string used in
1932 YAZ_MARC_LINE format. Default string is newline.
1934 Experimental support for MarcXChange. This format can be produced
1935 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1936 http://www.bs.dk/standards/MarcXchange.xsd
1938 Added yaz-client commands scansize that sets maximum number of
1939 entries to be returned by scan.
1941 --- 2.0.32 2005/01/11
1943 Added support for SRW scan in yaz-client and Generic Frontend Server.
1945 * Added whereInList member to SRW Scan Term.
1947 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1949 Fixed NMEM system to return aligned blocks on the smallest boundaries
1950 that are suitably aligned for all possible types on the particular
1951 architecture YAZ is being built for.
1953 --- 2.0.30 2005/01/04
1955 Fixed numerious warnings that was issued with newer versions of GCC.
1957 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1958 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1961 Make YAZ Generic Frontend Server slightly faster.
1963 Enhance (and reduce) logging for Generic Frontend Server.
1965 Revert YAZ log system so that it flushes every write operation
1966 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1968 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1969 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1970 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1971 will effectively disable old definitions.
1973 --- 2.0.28 2004/11/09
1975 Added yaz_log_time_format which specifies log format using
1978 Added yaz_log_module_level which returns mask for a module. Value
1979 is non-zero mask a if module is enabled; zero if disabled.
1981 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1982 in include/yaz/cql.h.
1984 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1986 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1988 Fixed bug #172: RPM builds does not enable SSL.
1990 Doxyfile.in part of dist. Doxyfile generated by configure.
1992 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1993 are given and the corresponding component does not exist.
1995 Extend CCL documentation in YAZ reference. Describe r=r.
1997 --- 2.0.26 2004/10/01
1999 Fixed MARC->MARCXML conversion to properly deal with
2000 fields, subfields, indicators having non-ASCII characters.
2002 Fixed MARC->MARCXML conversion so that ASCII control characters
2003 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2006 Added YAZ GFS support for conversion from Z39.50 surrogate
2007 diagnostics to SRW surrogate diagnostics.
2009 Bug fix: YAZ GFS did not return schema in explainResponse.
2011 --- 2.0.25 2004/09/30
2013 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2014 now converts recordSchema to elementSetName as well as schema URI.
2016 Fixed bug in COMSTACK that prevented HTTP request packages from being
2019 --- 2.0.24 2004/09/29
2021 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2022 does not require white-space before and after the dash in a range, e.g.
2023 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2026 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2027 due to new GCC removing "redundant" code.
2029 Added yaz-client commands scanpos and scanstep that sets preferred
2030 position and step-size for scan.
2032 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2034 Added CCL utility ccl_qual_buf which parses one or more CCL
2035 spec lines in a buffer.
2037 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2038 of name and value - ignoring empty lines and comments.
2040 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2042 Added odr_get_element_path which returns current element path for an
2043 ODR handle. This utility is useful in error handling or user-defined
2046 Added ODR_PRINT utility odr_set_stream which is is a more generic
2047 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2048 to a write function and pointer to close function. The close function - if
2049 non-NULL - will be called during odr_destroy.
2051 Fixed bug in CCL parser where truncation char was not removed from
2052 right side when truncation=both was in effect.
2054 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2057 --- 2.0.23 2004/08/11
2059 Fix buffer overrun in CQL parser when dealing with proximity (%).
2061 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2062 to UTF-8/UCS conversion is now only based on codetables.xml.
2064 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2066 --- 2.0.22 2004/08/06
2068 Add support for more "commit changes" in ZOOM (uses Extended Services).
2070 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2073 Yet another small fix for configure of SSL.
2075 --- 2.0.21 2004/05/14
2077 Fix SSL libs for configure when --with-openssl=DIR is given.
2079 --- 2.0.20 2004/05/10
2081 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2083 SSL comstack now uses yaz.pem certificate file on server side
2084 by default. Certificate filename can be configured by calling
2085 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2087 Fix bug regarding multiple calls to ZOOM_connection_connect.
2089 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2091 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2092 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2094 ZOOM now allows inspection of X509 peer certificate for verification.
2095 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2097 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2098 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2099 as "modular" but it simplifies things.
2101 Added cs_get_peer_certificate to that returns peer X509 PEM.
2103 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2104 NULL if SSL is unavailable.
2106 Documentation about MARC decoding tools.
2108 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2110 --- 2.0.19 2004/03/30
2112 Rename CHANGELOG to NEWS to follow GNU style packing.
2114 Fix bug with missing initialization of member in init_diagnostics.
2115 This bug affects threaded version of GFS server.
2117 --- 2.0.18 2004/03/20
2119 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2122 Ensure zlib.dll is packed with Windows install.
2124 --- 2.0.17 2004/03/17
2126 Fix encoding of xsd:string to use text instead of CDATA.
2128 Fix endless loop in CQL parser with unbalanced ".
2130 Use a more compact way to store MARC-8 conversion tables.
2132 --- 2.0.16 2004/03/16 Debian only
2134 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2137 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2142 --- 2.0.15 2004/03/01
2144 Another fix for decoding of XML packed records.
2146 --- 2.0.14 2004/02/25
2148 Fixes for Chunked encoding. White space not ignored after length spec.
2150 Update NS and use default NS for SRW diagnostic elements.
2152 --- 2.0.13 2004/02/23
2154 Implement ZOOM_resultset_cache_reset which resets record cache.
2156 Implement ZOOM_resultset_sort which sorts a result set.
2158 Implement chunked HTTP transfer.
2160 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2162 --- 2.0.12 2004/02/16
2164 Added member 'schema' to bend_explain_rr structure so that backend
2165 can specify explain record identifier. Defaults to Zeerex 2.0.
2167 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2169 --- 2.0.11 2004/02/16
2171 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2174 Added init command for yaz-client which sends "extra" init request.
2176 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2177 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2179 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2181 Make ZOOM error code for "invalid query".
2183 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2185 --- 2.0.10 2004/02/05
2187 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2190 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2192 Added option -p <file> to make Generic Frontend Server to write PID file.
2194 Added option -D to put Generic Frontend Server in background on its own.
2196 Make ZOOM C recognize option "password". If unset, "pass" is used
2197 (for backwards compatibility).
2199 Fixed a bug in Generic Frontend Server that could make it crash if a
2200 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2203 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2204 Must be issued before open, in order to be in effect.
2206 --- 2.0.9-6 2004/01/12 Debian/Windows
2208 Make the SRU server more picky WRT unknown params, etc.
2210 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2212 New YAZ client command, options, that sets Z39.50 options.
2214 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2215 options from a string of tokens (one token for each option bit).
2217 Update SRW diagnostic code messages.
2219 --- 2.0.9-5 2004/01/07 Debian/Windows
2221 Handle user defined stylesheet for SRW/SRU.
2223 --- 2.0.9-4 2004/01/06 Debian/Windows
2225 Fix bug in decoding of Content-Length.
2227 --- 2.0.9-3 2004/01/06 Debian/Windows
2229 Fix a bug with decoding of XML packed records.
2231 --- 2.0.9-2 2004/01/05 Debian only
2233 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2235 Fix bug in SRW/SRU diagnostics decoding.
2237 --- 2.0.9 2004/01/05
2239 Fixed bug in Generic Frontend Server which could drop records exceeding
2240 preferred message size. Reported and fixed by Irina Dijour.
2242 Fixed calculation of package size for structured records in Generic
2243 Frontend Server. Reported and fixed by Irina Dijour.
2245 Fixed namespace for SRW/SRU diagnostics.
2247 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2249 --- 2.0.8 2003/12/22
2251 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2252 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2255 CQL changes to reflect recent changes to the specification:
2256 * Documentation talks about context sets instead of index sets.
2257 * Documentation talks about indexes instead of qualifiers.
2258 * The CQL-to-PQF transformer's configuration file now uses
2259 "index.set.name = <attributes>" instead of the old form
2260 "qualifier.set.name = <attributes>". (Both forms are still
2261 understood but the latter is deprecated.)
2262 * CQL terms with no explicit index specified are now interpreted as
2263 cql.serverChoice instead of srw.serverChoice (which of course
2264 behaves exactly the same.)
2266 --- 2.0.7 2003/12/16
2268 MARC conversion can now generate ISO2709 output in another
2269 character set. yaz-marcdump uses this facility if you invoke it
2272 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2273 functions from there can be used from C++.
2275 --- 2.0.6 2003/12/04
2277 Frontend server now transfers memory from decoded packages to stream
2280 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2281 references to show up.
2283 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2284 the ZOOM Abstract API. The older names for the same options are still
2285 also supported for the benefit of old applications.
2287 ZOOM-C supports "implementationId" and "implementationVersion" options
2288 to go along with "implementationName". These allow the user code to
2289 specify identification strings to be sent to servers.
2290 Add OID for the new ExtLite attribute set.
2292 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2293 as requested/supplid by Ere Maijala <ere@atp.fi>
2295 For generic frontend server, reverse the order of
2296 "toolkit-supplied / application-supplied" strings sent as implementationId,
2297 Name and Version. Also, remove the spaces around the slash. This brings
2298 the GFS in line with the behaviour of ZOOM-C on the client side.
2300 Add function ZOOM_scanset_display_term.
2302 yaz-client shows scan displayTerm if present.
2304 Utility yaz-iconv is now installed by default along with the man page
2307 Extend configure check for OpenSSL to use pkg-config where available (such
2310 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2311 server to specify uid/gid/mask for socket using the format
2312 unix:[user=uid,][group=gid,][umask=mask,]file=path
2313 If file= is omitted the existing format is assumed, e.g.
2315 in which case the mask is 0666 (rw for everybody).
2317 Major restructure of YAZ source. All source in libyaz is in src directory.
2318 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2319 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2321 Added man page for utility yaz-marcdump (used to be called marcdump).
2322 yaz-marcdump is installed by 'make install'.
2324 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2325 of incoming package failed.
2327 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2329 Change prototype of odr_perror: add const to message string.
2331 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2333 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2334 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2335 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2336 DNS lookup. There should not be any compatibility problems with this
2337 assuming that blocking=1 or 0 is used.
2339 Fix bad reference in UNIX comstack in function cs_addrstr.
2341 Fix for compilation on AIX.
2343 The generic front-end server (server/seshigh.c) now supports returning
2344 Init diagnostics to the client in User-information-field, in
2345 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2348 --- 2.0.4 2003/09/04
2350 Allow any CQL relation (not just all,any,exact,scr).
2352 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2353 that features the same UI.
2355 Implemented command update0 in YAZ client which is equivalent to
2356 update but uses old of Ext Update ASN.1.
2358 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2359 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2360 Previously no OID was used for this info.
2362 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2363 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2364 returns 'malformed search term' otherwise.
2366 SortResponse member resultCount now set to NULL in sort handler of
2369 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2372 Add three new utility functions for translating OIDs between various
2373 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2374 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2375 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2376 char *oid_to_dotstring(const int *oid, char *oidbuf);
2377 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2379 Reverted modifications for ES Update definition for z_IU0Update
2380 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2381 is back to YAZ 2.0.2.
2383 String value attributes for CCL parser.
2385 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2386 which their FirstSearch server returns in Init responses, sometimes
2387 carrying useful diagnostic information when Init fails. This has the
2388 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2389 "z39.50/oclcui.asn", where its definition is somewhat different from
2390 what OCLC document on their web-site, as required to interoperate with
2393 Support for anonymous authentication in yaz-client. Use the command
2396 * Fix the OID of the Index Data-local "admin" Extended Service from
2397 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2398 the 1000, which indicates a locally-defined OID, was a mistake.
2400 --- 2.0.3 2003/06/20
2402 Fix CCL directive @case handling so that it affects string match for
2403 both CCL keywords and qualifiers.
2405 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2406 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2407 Decoder has been updated with ASN.1 changes as listed in
2408 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2409 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2410 z_IUUpdate, remains unchanged.
2412 ZOOM_record_get may now return a record in a specific character set.
2413 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2414 "from" is the character set of record as returned by target. "to" is
2415 the character set to be returned. If omitted, "to" is UTF-8.
2417 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2419 New ODR utility, odr_getelement, which returns name of element for
2420 which encoding/decoding failed.
2422 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2423 in cases where a required element was omitted.
2425 Bug fix: some MARC8 sequences were not converted.
2427 New ZOOM option "step" which specifies number of records to be
2428 retrieved in one chunk. Used in conjunction with "start" and "count".
2430 SRW support for yaz-client. Use scheme http: to use it, e.g.
2433 yaz-client no longer does (un)intelligent character set conversions
2434 by default. Can be enabled with charset and marc_charset commands.
2436 xmalloc trace fix for 64-bit systems such as DEC alpha.
2438 Solaris 2.6 compile fix.
2440 New function, cql_strerror() translates SRW error codes, as returned
2441 by cql_transform_error(), into human-readable English strings. Used
2442 in yaz-client diagnostics when appropriate.
2444 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2445 converts it into a type-1 query which is sent to the server. This
2446 makes CQL available for use with all Z-servers, as opposed to the tiny
2447 minority that can handle CQL queries themselves.
2449 --- 2.0.2 2003/04/28
2451 New Debian package layout similar to the Redhat Package layout.
2453 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2454 and search result respectively.
2456 --- 2.0.1 2003/04/25
2458 Redhat package is now several packages: libyaz (runtime libraries),
2459 libyaz-devel (development and documentation, and yaz (utility programs).
2460 Package spec file by Morten Bogeskov.
2462 New member 'schema' in struct bend_fetch_rr which the name of requested
2463 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2464 handler MAY set this to reflect the schema of the returned record.
2466 New member 'display_term' in struct scan_entry. GFS now sets member entries
2467 and allocates scan entries to be filled by user scan handler. In previous
2468 version, entries member was allocated by the scan handler. That still works,
2469 but the GFS will ignore member display_term - assuming it was NOT set by
2470 the handler. The fact that the GFS now allocates the entries both allows
2471 for new members and makes a scan handler easier to write.
2473 Fix CQL lex buffer overflow.
2475 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2476 SRU default recordPacking is string.
2478 SRU protocol support for frontend server.
2480 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2482 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2484 Added scan for the ZOOM shell (zoomsh).
2488 * String Identifers for Schemas (Amendment 5).
2489 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2490 Old definition for schema
2491 Odr_oid *schema; /* OPT */
2496 Z_InternationalString *uri;
2497 #define Z_Schema_oid 1
2498 #define Z_Schema_uri 2
2501 * resultCount parameter to Sort Response (Amendment 1).
2502 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2504 Support for SRW 1.0 over HTTP. This is an optional feature and
2505 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2508 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2509 on the same port. SRW SearchRetrieveRequests are mapped
2510 to bend_init,bend_search,bend_fetch,bend_close.
2512 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2514 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2515 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2517 ZOOM connections are SRW based if schem http is used for hostname
2518 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2519 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2521 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2522 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2523 distance=n, order=true/false, relation=le, prox unit=word. If
2524 n is omitted, distance 1 is used.
2526 Fixed problem with C compiler include path in wrong order.
2528 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2529 on Solaris. Patch from Ko van der Sloot.
2531 New MARC decode API. All new functions operate on a yaz_marc_t
2532 handle. The most important new functions are: yaz_marc_create,
2533 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2534 decode and destroy respectively. Decoder can produce formats
2535 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2536 include/yaz/marcdisp.h.
2538 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2539 to UTF-8, UCS-32, wchar_t or Latin-1.
2541 * Prototypes for yaz_iconv_-functions moved to separate header
2542 include/yaz/yaz-iconv.h.
2544 Make a few private functions 'static' in unix.c. This prevents
2545 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2547 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2548 are set when Init Response is received.
2550 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2551 but returns diagnostic set as well.
2553 New function yaz_strerror which is a portable wrapper for
2554 strerror/strerror_r/GetLastMessage.
2556 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2557 is returned for MARC. If type is "oai", then OAI MARC is returned.
2559 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2562 --- 1.9.2 2002/11/26
2564 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2566 Fix bad race conditions on SIGTERM and terminate gracefully in
2569 Move retrieval (data1) module to Zebra since nobody seems to be
2572 Add GRS-1 render for ZOOM using same format as yaz-client.
2574 --- 1.9.1 2002/10/05
2576 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2578 Fix broken ESpec handling in data1 module.
2580 SGML reader parses comments and makes them part of the data1 tree.
2582 Added several type casts so that YAZ compiles as C++ code.
2584 ZOOM didn't handle PDU encoding failures properly.
2586 Added more Bib-1 diagnostics (approved extensions).
2588 GNU configure: better check for iconv.
2590 More portable use of accept, getpeername. Check for socklen_t. Use
2591 int/size_t if socklen_t is not defined.
2595 PQF parser rejects bad queries - including those with extra
2596 characters in them. PQF parser used to silently ignore that.
2597 Cleaner API for PQF added, which allows you to get detailed
2598 error information for bad queries (see yaz/pquery.h).
2600 Fixed bug in ZOOM_record_get for type "database".
2602 Implemented mini iconv library supporting conversions between
2603 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2605 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2607 --- 1.8.9 2002/08/20
2609 Fixed ZOOM C record cache so that preferredRecordSyntax and
2610 elementSetName is used to check for already fetched records.
2612 --- 1.8.8 2002/08/02
2614 Added three members in bend_initrequest structure to facilitate
2615 character set negotiation.
2617 Fixed a bug in frontend server that could cause indefinite
2618 loops under rare conditions.
2620 Revised character set utilities (charneg.h) so that encoding
2621 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2623 For PQF, directive @term <type> sets term type for Scan/Search.
2624 Here <type> is general, string, numeric, null. The term type
2625 is inherited - just like @attr.
2627 New call odr_set_charset that sets character set conversion for
2628 international-strings on a ODR stream. Prototype is:
2629 int odr_set_charset(ODR o, const char *to, const char *from);
2630 The InternationalString is still represented as C string in YAZ
2631 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2632 won't). On the protocol level, you can use any encoding.
2634 Support for UNIX sockets in ZOOM.
2636 Solaris recv sometimes returns errno == ENOENT. It is treated as
2637 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2639 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2640 both client and server. Code by Morten Bogeskov.
2642 --- 1.8.7 2002/05/22
2644 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2645 that they can be used directly from Visual Basic. You must recompile
2646 your windows APP if you're using ZOOM.
2648 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2649 Commands "lang" and "charset" sets language and character set respectively.
2650 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2651 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2653 Attributes from multiple CCL fields may be OR'ed rather than merged
2654 using directive "@field or". Fields are still merged by default -
2655 equivalent to "@field merge".
2657 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2660 Fixed bug in zget for parameter ExtendedServicesResponse.
2664 --- 1.8.6 2002/03/25
2666 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2668 Client displays USR.1:SearchResult-1 (hits per term).
2670 Additional Search Info for search in Generic Frontend Server.
2672 Fixed CCL parsing of "field=s".
2674 WIN32 installer - using the excellent NSIS software from nullsoft.
2676 Fixed CCL parsing of "field = - <number>".
2678 Added function yaz_marc_decode that decodes MARC for line mode
2679 display or XML (similar to that used by JZKit).
2681 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2682 Z39.50. But ISO/ILL was, however.
2684 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2685 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2687 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2688 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2690 --- 1.8.5 2002/02/03
2692 New YAZ client features: Command completion and new commands:
2693 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2694 Code provided by Jacob Poulsen.
2696 New call oid_trav, that visits all registered OIDs via callback.
2698 Function ZOOM_record_get now returns const char pointer rather than
2699 void pointer. It saves a lot of type casts.
2701 For YAZ client, command "auth" now allows you to set authentication
2702 in IdPass style. It is enabled when three tokens are given - order
2703 is user, group and password.
2705 Fix memory leaks in MARC record handling for ZOOM.
2707 New option for YAZ client, -k <kilobytes> that sets
2708 maximum record size. Similar to -k option for generic frontend
2709 server and yaz-ztest.
2711 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2713 Prefix query parser reports "fail" when bad attribute set is given.
2715 Fix in MARC decoder. Proximity logging. Fix for attribute set
2716 in scan handler for server. Patches by Shigeru Ishida.
2718 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2721 Configure option --with-openssl=<dir> now works when a directory is
2722 specified. Patch provided by Morten Bogeskov.
2724 New option for YAZ client, -u <auth>, that sets authentication.
2726 ZOOM fix: error information was sometimes "missing", since error
2727 was cleared/reset too when it shouldn't.
2729 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2731 --- 1.8.4 2002/01/04
2733 Scan for ZOOM API. New object ZOOM_scanset. New functions
2734 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2735 ZOOM_scanset_destroy.
2737 New ZOOM function, ZOOM_connection_last_event, that returns type
2738 of last event (such as "receive data", "send data", "apdu received",
2741 New ZOOM option, schema, that specifies schema for retrieval.
2743 New CCL feature. Qualifiers can be aliases for one or more
2744 other qualifiers (if more than one is given, OR is used).
2746 ZOOM uses named result sets if target supports it.
2748 Two new YAZ client commands: . (dot, which sources a script of YAZ
2749 client commands), and ! (to execute shell command.). Implemented
2752 Working on Debian packages.
2754 --- 1.8.3 2001/11/19
2756 YAZ client enables named result sets only if target supports it.
2758 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2760 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2761 with key="host" to get same result.
2763 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2764 Function Z3950_resultset_record(s) returns references to records
2765 "owned" by resultset. To become owner use Z3950_record_clone.
2767 Function z_ext_record handles Extended Services. Thanks to
2770 --- 1.8.2 2001/11/12
2772 CCL Parser fix: ignore token comma when dealing with and-lists.
2774 Documentation updates for COMSTACK.
2776 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2777 Changed prototype Z3950_records. For some functions, int parameters
2778 were changed to size_t.
2780 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2783 New MARC decode/display function, marc_display_exl, which properly rejects
2784 non-ISO2709 records. YAZ client uses it.
2786 --- 1.8.1 2001/10/29
2788 Fix bug: local attribute set wasn't set correctly in PQF strings.
2792 * Old Z39.50 codecs no longer supported.
2794 Added ZOOM C binding. See http://zoom.z3950.org/
2796 Renamed states for COMSTACKs to avoid confusion with events.
2798 Implemented cs_look and proper cs_rcvconnect.
2800 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2802 Configure detects POSIX threads on OpenBSD.
2804 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2805 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2807 When error is returned from present handler, non-surrogate diagnostic
2808 is returned in present response (and fetch handler is no longer called).
2810 * Minor adjustments to pquery parser (PQF). Token characters may be
2811 escaped by using backslash (C-style).
2813 PQF parser allows string attribute values to be specified. For @attr,
2814 non-numeric characters after the equal-sign are treated as strings
2815 (e.g. @attr 9=title).
2817 CCL trunction character may be defined (@truncation in file)
2819 * function zget_ExtendedServicesRequest sets waitAction to
2820 waitIfPossible (was wait).
2822 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2825 CCL operator names may be set in field definition files (CCL_bibset).
2826 See ccl/bib1 for an example.
2828 Fixes in ASN.1 compiler for C++ compatibility.
2830 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2831 and "op_or" to avoid conflict with C++.
2833 Fixed problem with GNU readline detection on Redhat 7.0.
2835 Added step-size for Scan backend handler.
2837 Fixed bug that made the frontend server crash when no attribute
2838 set was specified for scan.
2840 Front-end server automatically switches to original working directory
2841 when installed as an NT service. Previously -w had to be specified to
2844 Added extended attributes for retrieval module (data1), so that data1
2845 records carry d1_readXML/SGML attributes. d1_read also supports
2846 null-data rules ( <tag/>)
2848 On UNIX when POSIX threads are available, a separate library libyazthread
2849 is created. Programmers should link with that library and the yaz library
2850 when using threads. The reason for the split was that some applications
2851 on Linux, such as Apache, doesn't work well when using shared objects that
2854 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2855 (or any frontend server) in SSL mode by specifying ssl: followed by
2856 address. Only tested on UNIX.
2858 Added feature for CCL module. Virtual structure s=al or s=ol generates
2859 and-list and or-list respectively instead of phrase search.
2863 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2864 log_mask_str. This was done to avoid name conflicts with other libraries
2865 (such as other PHP extensions).
2867 Added raw OID member for preferred record syntax (request_format_raw)
2868 and returned record syntax (output_format_raw) for backend fetch method.
2870 Config file yaz-config now accepts options so that it returns specific
2871 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2873 Shared library support for UNIX using GNU libtool.
2875 * Modified backend interface. Request/Response struct's replaced by
2876 one read/write C struct. For example bend_fetchrequest and
2877 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2878 Every handler - even search has to be registered in bend_init
2879 handler. This means that the YAZ library no longer refers to
2880 external functions and it makes it possible to make the whole
2881 thing a single DLL/SO.
2883 Added Segment handler for backend server.
2885 Added Zmbol/Zebra administrative functions to YAZ client.
2887 Threaded frontend server on UNIX (when POSIX Threads are available).
2888 Starting the server with option -T enables multi-threading.
2892 Added configure option --enable-comp/disable-comp to control use
2893 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2894 located in sub directory asn.
2896 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2897 in ${exec_prefix}/bin along with the other programs yaz-client and
2900 GNU automake used to maintain makefiles.
2902 Added several OID's.
2904 Changed retrieval module so that we can load records with no abstract
2905 syntax defined. Tagpaths in these records are fully composed of string
2908 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2912 On UNIX, the generated makefile now supports a proper 'make install'.
2913 The prefix can be set via GNU configure to set the install location
2914 (default is /usr/local).
2916 * YAZ programs client and ztest were renamed to yaz-client and
2917 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2918 locations, such as /usr/bin,/usr/local/bin,etc.
2920 * YAZ Header files were moved from include to include/yaz. YAZ Header
2921 files are referred to as include <yaz/log.h> rather than <log.h>.
2922 The YAZ include path (-I ..) is therefore the same as before. Programmers
2923 should update their #include statements or use -Ipath/include/yaz
2924 instead. The main motivation for doing this change is that YAZ header files
2925 can be installed in "standard" locations /usr/include,/usr/local/include
2926 without introducing conflicts, since ALL YAZ header files are stored
2927 in subdirectory yaz (under /usr/include for example).
2929 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2930 rather than project/workspace files. We switched because project files
2931 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2934 Changed name of logging function, logf, to yaz_log, to prevent name
2935 clash with some math-log functions. The YAZ header log.h defines logf
2936 to yaz_log (#define) so there should be no incompatibilities by this
2939 Added bend_start/bend_stop handlers for server. These handler are
2940 called on start/stop of server. For windows they are called whenever
2941 a service is started/stopped.
2943 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2944 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2945 in util/yc.tcl. The auto-generated C code structures are, in a few
2946 cases, incompatible with the old decoders. There are differences in the
2947 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2948 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2949 The preprocessor variable ASN_COMPILED is defined when the compiled
2950 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2951 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2952 wish to use the old encoders/decoders you can specify --disable-yc
2955 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2956 version so that it supports both new - and old version of DB Update
2958 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2959 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2960 change. The name parameter can be set to 0 in which no name is specified
2961 for the construction. The macros odr_implicit and odr_explicit sets name
2962 parameter to zero for the construction involved. New macros
2963 odr_implicit_tag and odr_explicit_tag are similar to the others,
2964 except that a name parameter is added. For programmers' that don't use
2965 ODR they probably only need to change the call to z_APDU and z_External.
2967 Added access control facility by interfacing the TCP wrapper library.
2968 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2969 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2970 name of the daemon and enables the access control as specified in
2971 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2973 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2974 den Dool <H.M.vdnDool@kub.nl>.
2976 Added reference ID parameter to most functions in server API - refer
2977 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2979 Changed name of ccl library to libccl.a (was ccl.a).
2981 Fixed bug in decoder for Explain (Category TargetInfo).
2983 Added support for GNU readline in client. Thanks to Jacob Poulsen
2984 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2986 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2987 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2988 IMPLEMENTATION! This change was made to the development version before
2989 the ZIG decided to retract the amendment. If any users MUST be
2990 compatible with the original Update definition, PLEASE CONTACT US, and
2991 we will include a separate definition corresponding to the old Update
2992 ES. Note that because of the change to the ASN.1 of the
2993 TaskPackageRecordStructure we cannot define a single structure that
2994 will support both versions.
2996 * Added const modifier to buffer parameter for some ODR/BER encoding
2997 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2998 completeWAIS, odr_dumpBER.
3000 Fixed bug in client.c which caused a crash when a scanResponse didn't
3001 contain positionOfTerm.
3003 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3004 * will cause an error in a client if a non-YAZ target sends both a
3005 * list of Scan entries and non-surrogate diagnostics.
3007 Retrieval module enhancements. Tag sets may be typed in the reference
3008 to it. From the .abs-file the "tagset" directive takes a third optional
3009 integer type for the tag set referenced. From a .tag-file the "include"
3010 directive takes a third optional type as well. The old "type" directive
3011 in the tag set itself is still recognized but acts as the default type
3014 Backend interface change. Individual Scan terms returned from bend_scan
3015 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3016 in include/backend.h.
3018 Retrieval module enhancements. Multiple tag sets and attribute sets may
3019 be specified in abstract syntax specs. Revised the error/warning for
3020 logging messages reported by the retrieval module when reading the
3023 Object Identifier system (oid_..) changed. The API is backwards
3024 compatible but the oid-routines now allocates new OID's when needed.
3025 Raw OID's may be specified in oid_getvalbyname.
3027 YAZ now uses GNU configure to generate Makefile(s).
3029 * Minor changes in some of the member names of DeleteResultSetRequest and
3030 DeleteResultSetResponse. See include/proto.h.
3032 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3033 and added member 'languages' in TargetInfo (which was missing).
3035 Changed the way attribute sets are handled in the retrieval
3036 module. These are now cached, just like the abstract syntaxes
3039 Changed YAZ so that it links with compiled ASN.1.
3041 Added Explain-schema definitions and mapping routines. The following
3042 Explain categories have been implemented: AttributeDetails,
3043 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3045 Fixed minor bug in Windows version of Server Library.
3047 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3049 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3051 Added EXTERNAL: UNIverse Resource Report (non-standard).
3053 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3054 ENUMERATED and SET OF.
3056 * Added 'const' to some of the char pointer arguments for the
3057 functions, data1_read_node, data1_getelementbytagname,
3058 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3061 Fixed bug in data1_insert_taggeddata - the last_child member of
3062 parent wasn't initialised.
3064 * Changed data1_read_record and data1_read_node so that the supplied
3065 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3066 doesn't refer to any parts of the "SGML"-buffer.
3068 Fixed bug in server library (Windows version of statserv_remove).
3070 * Changed code so that it compiles as C++. The type definition
3071 of Odr_fun which is a member of Odr_arm was changed. The result is,
3072 that an explicit typecast is needed for the fun pointer when
3073 using Odr_arm - as in:
3074 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3076 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3078 Implemented the new structured date and time definition as approved
3079 by the ZIG. Added schemaId element to the specificTag in Espec-1
3080 (also approved at the last ZIG). Thanks to RVDM.
3082 Added some Object identifiers (RVDM).
3084 Changed the Update Extended Service (RVDM).
3086 Added command "refid" to client which specifies referenceId for
3087 the following requests.
3089 Implemented extended service handling for server. See ztest.c
3090 for an example as well as backend.h. New handlers are registerd
3091 in the Init handler.
3093 * Changed interface for sort in server.
3095 Added new members to statserv_options_block. It allows a server
3096 to read options from another source than just the command line. Thanks
3097 to Charles Woodfield.
3099 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3100 renamed to zboolean. Some C++ compilers complained about the name.
3102 Minor changes to gils.abs. Added index 's' (sort) on title
3103 and date/time-last-modified.
3105 --- 1.4pl2 1998/1/30
3107 Fixed bug in server library regarding inetd mode (-i). This bug
3108 was introduced by release 1.4.
3110 --- 1.4pl1 1998/1/29
3112 Added sort facility in client and backend server interface.
3114 Fixed problem with dependencies in Makefile(s).
3116 Fixed bugs for encoders/decoders of extended services and
3119 Implemented sub-tree feature for schemas. Sub-trees are
3120 referenced in *.abs-files. See explain.abs for an example
3121 of the use of this feature.
3123 Modified bib1.att; local attributes for ANY didn't include
3124 ANY itself (only affects use of the retrieval module).
3126 Fixed bug in plain SGML reader in function data1_read_node:
3127 tags with prefix "var" was incorrectly interpreted as variants.
3129 Added feature "sub-schemas" to enable references to - and definitions
3130 of - group of elements.
3132 * Removed member parent from type data1_element (in data1.h).
3134 Implemented function odr_nullval() that returns the value of
3137 * Removed member num_children from data1_node (in data1.h).
3139 Made NT service interface part of the server library. The
3140 function statserv_main uses the NT service when required and
3141 calls the statserv_start / statserv_close routines.
3143 Routine zget_SearchRequest and zget_PresentRequest fills
3144 resultSetName/Id member with "default" instead of "Default".
3146 Fixed memory leak in server. Request queue member wasn't freed.
3148 Fixed nmem_exit so that memory is freed.
3152 Revised the CCL parser utility to be thread safe.
3154 Added function, oid_ent_to_oid, to replace the function
3155 oid_getoidbyent, which is not thread safe.
3157 * Added nmem_init and nmem_exit to initialize and release
3158 NMEM resources. Function nmem_init should be called once in the
3159 initial thread before NMEM/ODR is used. statserv.c and client.c
3160 have been changed accordingly. The change was necessary to make
3161 NMEM thread safe. The NMEM memory pool is shared amongst threads
3162 in a process. Unix-based applications will still work fine without
3165 Added NT Services interface for the the Z39.50 (statserv) Server.
3166 Refer to the ztest.c source on the usage.
3168 Windows 95/NT port using MSVC5.0. Project files are included in the
3171 * Defined new 'global' handle for the retrieval (data1) system. The
3172 new handled, data1_handle, describes the state of the data1 system.
3173 This handle is passed as first argument to virtually all
3174 data1 related routines. The functions data1_create and data1_destroy
3175 creates and destroys a data1 handle respectively.
3177 Added ODR encode stream member to all backend request structures
3178 init, search, scan etc. This stream should be used to allocate all
3179 memory used for the response when thread safe operation is needed.
3181 Changed the comstack utility, cs_addstr, to be thread safe. The
3182 returned hostname string returned by the function is now part the
3185 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3186 function. The cs_straddr takes a COMSTACK handle as argument, so this
3187 function must be used after cs_create and before bind/connect.
3188 This function is thread safe.
3190 Moved test server to 'ztest' directory - generic server code still
3191 in 'server' directory.
3193 Made prefix query (pquery.c) utility thread safe.
3195 Added new function modifier YAZ_EXPORT to 'export' public DLL
3196 functions when using windows (see include/yconfig.h).
3198 Added definitions to the OID database (util/oid.c) (RVDM).
3200 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3202 Added call to ccl_rpn_delete in client program.
3204 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3205 release of RPN structure.
3207 Added support for C++, headers uses extern "C" for public definitions.
3208 With input from RVDM.
3210 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3211 Thanks to Ronald van der Meer (RVDM).
3213 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3215 Added support for private extensions to the OID database
3216 (oid_setprivateoids()). Thanks to RVDM.
3218 Added optional, physical ANY (key replication)
3220 Fixed null-reference problem in GRS-1 output filter.
3222 Proximity operator added to Prefix Query Format (PQF).
3224 In test client command "base" accepts multiple databases.
3226 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3230 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3232 Smallish bug-fixes in the new encoders/decoders (explain).
3234 Bug fixed in DeleteRequest.
3236 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3238 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3240 Added SOIF syntax (using private OID for now) to retrieval module and client.
3242 Added Update extended service.
3244 Added SearchResult-1 additional info structure.
3246 Added optional CCL (ISO8777) interpreter as separate module. Available
3249 --- 1.2 1996/6/10 (1st anniversary release)
3251 Added Summary record syntax. Lightly tested.
3253 Added OPAC record syntax. Untested.
3255 Added ResourceReport service encoders/decoders. Untested.
3257 Fixed bug in z_Unit - wrong tagging on unitSystem.
3259 Fixed bug in the DiagRecs decoder.
3261 Added options for max PDU size and session timeout to frontend-server.
3263 Added documentation of query-language parsers and other supporting utilities.
3265 [frontend-server] Added Attribute set to the bend_scanrequest API.
3267 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3268 surrogate diagnostics were generated.
3270 [retrieval] Allow multiple local values for attribute.
3272 [retrieval] Allow multiple attributes per element in .abs files. index type.
3274 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3276 --- 1.1pl2 1996/4/10
3278 Minor changes, mostly specific to Zebra's requirements (retrieval)
3282 Repaired bug in frontend server when running multiple listening
3283 endpoints in dynamic mode.
3285 z_External() now won't break if a known, ASN.1 value comes encapsulated
3286 in an octet-string. The value will pass through unmodified in an Odr_oct.
3288 Added a bit of code to the demo client to decode & display
3289 ASN.1-structured records represented in the octet-aligned branch of
3290 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3292 Added z_ext_getentbyref() to the ASN module. Doc updated.
3294 * Completed the SCAN definition in the ASN module. This may break SCAN
3295 code based on older YAZ-versions at compile-time. The fix is easy -
3298 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3299 under the SCAN definition. Remember to initialize this, server-people.
3301 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3302 that this does not extend to ODR and ASN.
3304 Comstack allows insertion of established socket (primarily for
3305 inetd-operation of servers). Doc updated.
3307 Front-end server can now start from the inetd in TCP mode. Doc
3310 --- 1.0pl4 1996/1/24
3314 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3315 the rank and record number.
3317 Adjustments to the frontend server.
3319 Fixed diagnostic BER dumper. It ignored the file argument.
3323 Various changes to retrieval module.
3325 Changed the union discriminators of the protocol files from enums to
3326 ints paired with #defines.
3328 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3331 *Changed operator in the RPN structure to 'roperator', again to avoid a
3334 Fixed problems in Explain decoders/encoders.
3336 --- 1.0pl2 1995/12/6
3338 Memory bug in log module fixed.
3340 --- 1.0pl1 1995/12/5
3342 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3344 Bug in Explain DatabaseInfo module fixed.
3346 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3350 The shift to v1.0 signals that we now consider the *core* functionality
3351 of YAZ reasonably stable (the core being more or less equivalent to
3352 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3353 tested (Explain not at all - though that will happen soonish).
3355 Minor changes to code to support Windows port.
3357 Various minor changes after we're getting to use GRS-1 & co. more.
3359 Added Espec-1 format.
3361 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3362 of the protocol and it cannot be selected when encoding (maps into 'string'
3363 when decoding). Needed to talk to some servers.
3365 Demo client can request simple element set names.
3367 Added Diagnostic Format encoders/decoders.
3369 Added simple Close handling to frontend server (no hooks for resource
3370 reporting yet), and demonstration client.
3372 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3374 --- 1.0b3 1995/08/24
3376 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3377 handled incorrectly when records were requested in the searchResponse. This
3378 will only affect you if you use the frontend-server.
3380 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3381 Test-client will ask for and print GRS1. Ztest will return dummy records
3384 Added Explain encoders/decoders to the service-level API. Untested.
3386 Added Extended Services: Item Order encoders and decoders to the Service-
3387 level API. Untested. We could use a recent copy of the pertinent bits
3388 of the ILL protocol to add those bits.
3390 Added diagnostic format 1 encoders/decoders to the service-level API.
3393 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3394 odr_cons.c, which causes a more correct output.
3396 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3397 was always set to 0 when no records were requested in the searchRequest.
3399 * Added better external-handling. This shouldn't harm old code that
3400 *encodes* externals. It can break code that looks for a
3401 'single-ASN1-type' representation, since those types that are known
3402 are now decoded immediately. Look at the SUTRS sample code in
3403 seshigh.c and client.c. Documentation updated.
3405 Handling of structured records in bend_fetchresponse. Length -1 marks
3406 structured record, type is deduced from format field.
3408 --- 1.0b2 1995/06/27
3409 Fairly quick maintenance release to add SUTRS support.
3411 Fixed handling of SUTRS records in the demonstration client.
3413 * Added format field to the bend_fetchrequest and bend_fetchresponce
3414 structures of the backend API (frontend server). When the record is
3415 returned, the value of the format field is mapped to an OID. The
3416 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3417 of the record. The special value VAL_NONE in the bend_request means
3418 that no specific format was requested by the client. Documentation
3419 updated accordingly. Test server (ztest) will return a fixed dummy
3420 SUTRS record if your client requests SUTRS.
3422 Documentation updated accordingly.
3424 You can now set external libraries and RANLIB support in the top-level
3428 First public release.
