1 Fix proxy/host problem for ZOOM that could occur if unix sockets
4 New Debian package libyaz4-dbg.
6 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
7 differently in tcpip_close.
11 Windows installer of YAZ includes YAZ4J as a component.
13 CQL: allow "extra terms" again, by default. Thus, the CQL parser
14 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
15 and earlier. CQL parser may operate in strict mode where queries
16 not conforming to the standard BNF are rejected (syntax error).
17 Whether the CQL parser operates in strict mode is controlled with
18 cql_parser_strict . Strict mode enabled with option -S for utilities
19 cql2pqf and cql2xcql .
21 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
25 New charset, MARC-8c, which is like MARC-8 but allows control characters
26 0x01 through 0x1F, except ESC to be passed through verbatim.
28 Fix a problem with duplicate sub field character in MARC output. Problem
29 happened only when output was MARC-8 encoded.
33 yaz-ztest: Use hash for fake hit count. Before, random number was used.
34 This is problematic for unit tests using yaz-ztest. This patch also makes
35 a hash for CQL queries. For RPN, any term with a leading digit will be
36 treated as pseudu hit count (to force any particular hit count by a client).
38 yaz-ztest: return unique MARC dummy records. Beyond record offset
39 24, the author surname is patched with offset to make all records
42 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
43 on system wide default (/proc/sys/net/ipv6/bindv6only).
44 @4 binds to IPV4 only. @6 binds to IPV6 only.
46 Update CQL API documentation a bit
48 CQL: don't accept extra terms for queries. Makes the CQL parser
49 stricly conformant to the standard.
53 GFS: scan handler gets extra_args from request and may return extra
54 response data . That's for SRU only.
56 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
60 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
62 OPACXML: sync spelling of availabilityDate in XML to that of Schema
63 opaxxml.xsd. The schema had the correct spelling of this member always.
64 The ASN.1 was mis-spelled and still is (API change) - we are
65 not changing this. However, the OPAC to XML conversion had yet
68 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
71 New function, z_ext_record_oid_nmem, which is similar to
72 z_ext_record_oid but takes NMEM rather than ODR
76 ICU: New conversion element 'join' which joins tokens into one
77 with a custom character given by rule attribute.
81 New GFS search member: present_number. This is a hint to the
82 search handler how many records are going to be fetched immediately
83 following search. There's no guarantee that it's going to be the case,
84 since it depends on hit count (for Z39.50 piggyback) and whether errors
87 Make a few functions static (private). The functions getbyte_stream,
88 ungetbyte_stream and yaz_gets are now private. They were never declared
91 yaz-marcdump: exit(5) for serious decoding errors
93 ISO2709 decoding: be more picky WRT header
95 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
96 was only used as to indicate that next-result-set-position should be
98 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
99 Based on patch from Ashley Sanders.
101 Make some functions static/private in PQF parsing. Those functions were
102 never declared in a public header and so should not be in use by
103 applications based on YAZ.
105 --- 4.2.47 2012/11/23
107 ZOOM: special options to control APDU logging.
108 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
109 logging of APDUs until "saveAPDU" option is set again. If logging is
110 already enabled the effect is that current APDU buffer is cleared.
111 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
112 logging (default behavior on new connection).
113 The APDUs sent/received can be obtained by using
114 Using ZOOM_connection_option_get(c, "APDU") or
115 ZOOM_connection_option_getl(c, "APDU", &l).
117 GFS: relay implementation_version from backend
118 From 3.0.40 and later, implementation_version from backend was
119 not used in init response at all.
121 --- 4.2.46 2012/11/15
123 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
124 mode at all. Probably never did.
126 Make a new version of ztest.pem that, at least, is not expired.
128 --- 4.2.45 2012/11/13
130 Fix description of CCL directive 'case'.
132 More tight checking of form arguments (yaz_uri_to_array). Makes
133 YAZ better at rejecting big and/or bad POSTs.
135 SRU decoding does not report more than up to 10 invalid arguments.
137 rpn2cql: less quotes in generated terms. Semantics unchanged, but
138 it's prettier this way.
140 --- 4.2.44 2012/10/25
142 New utility yaz_decode_init_diag. Defined in proto.h.
144 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
145 given for unix local socket.
146 The COMSTACK string for doing so is:
149 unix:/myfile:tcp:localhost:9999/mybase
150 unix:/myfile:localhost:9999/mybase
151 unix:/myfile:http://fakehost/mybase
153 debian: Use dpkg-buildflags in build process.
155 --- 4.2.43 2012/10/19
157 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
158 global's SRU service uses a recordPosition scheme starting from zero.
159 First record's position should be one
160 according to the standard.
162 --- 4.2.42 2012/10/18
164 Allow more namespaces for SRU. This is to allow, for example, an
165 incorrect namespace returned from server
166 http://services.igi-global.com/sru .
168 Minor fixes for compilation on Windows.
170 --- 4.2.41 2012/10/11
172 daemon: log total number of bad signals from child on stop so that it
173 is more easy to spot problems with child worker processes.
175 retrieval: empty backend name attribute omits element set
176 from being used in retrieval.
178 --- 4.2.40 2012/10/04
180 Implement Solr sort strategy "solr", similar to sru11 sorting.
181 This will implement the correct parameters on Solr requst to do
184 --- 4.2.39 2012/09/28
186 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
189 MARC: Extra/missing indicator handled for MARCXML.
190 The indicator length is given in header and is the same for the
191 whole record. If attributes ind1, ind2 are missing, then content
192 character defaults to blank. Extra indicator attributes (beyond)
193 indicator length are treated as an error.
195 Reformat: delete trailing whitespace
197 --- 4.2.38 2012/09/17
199 MARC: fix non-ASCII characters for leader. This is to ensure we can
200 generate XML in UTF-8.
202 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
203 in one node with structure word.
205 --- 4.2.37 2012/09/04
207 yaz-json-parse: JSON output may be pretty printed by using option
210 Increase default value of max message for Z39.50 Init for GFS, ZOOM
211 and yaz-client. Old value was 1 MB. New value is 64 MB.
213 --- 4.2.36 2012/08/22
215 yaz-client: don't display bogus records from SRU servers. Some SRU servers
216 return more records than given by *maximumRecords*. Skipping those in
219 record_render: simplify buffer return handling and fix at least one bad
220 memory reference, that broke the test_embed_record sometimes.
222 Allow http://user:pass@host notation for yaz_url_exec.
224 zoomsh: allow shell command to be executed. Via the system(3) call.
226 yaz_poll: Allow num_fds == 0
228 yaz-client: fix bad encoding of "itemorder item". The itemorder
229 item <no> - command forgot to use length of encoded Item Request
230 package. Error present since YAZ 3.
232 yaz-ztest: fix bad usage of session handle. Bug was introduced when
233 result sets were saved (271a9c83).
235 SRU recordPacking: guess record packing in response rather than looking
236 at the recordPacking element which, OF COURSE, changed semantics in SRU
239 Decode SRU 2.0 responses. The official namespace for responses, according
240 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
241 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
242 nature.com's server, however, usee namespace
243 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
244 we are now using a glob-expr to match up the namespace. ZOOM C and
245 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
246 I can not find a single real example showing the "real" namespace in
247 the documentation from OASIS. The namespace for requests is different
248 from responses, but this is not added to YAZ yet, when we don't encode
251 --- 4.2.35 2012/06/26
253 zoom/record_render: add support for Base64 decoding fo MARC records
254 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
255 which will decode base64 + ISO2709 marc-8 encoded material from text node
258 --- 4.2.34 2012/06/07
260 Add missing definitions ZOOM_resultset_get_facet_field_by_index
261 and ZOOM_resultset_facets_names.
263 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
266 Change APDU dump printing to avoid long leading blanks. For levels 16
267 or larger the level is shown and the indentation is truncated but
268 recursed with modula 8. This makes it still reasonable easy to read
269 - even for nested BER dumps.
271 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
272 return 0 (incomplete package) in case where the BER package was
273 considered too nested (return value of -2).
275 dumpber: lines of level 15 are not indented further. Two spaces per
276 indentation; indentation 15 or more is indented to a fixed indentation
277 and augmented with a level=<no> indication.
279 zoomsh: increase max size of command+args
281 GFS: No limit in RPN buf size in CQL to RPN conversion.
283 --- 4.2.33 2012/05/09
285 New function for daemon utility, yaz_daemon_stop .
287 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
289 --- 4.2.32 2012/04/25
291 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
292 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
294 --- 4.2.31 2012/04/23
296 YAZ daemon utility relays SIGUSR1 to child process.
298 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
299 would result in en empty database list - which in turn would result in
300 encoding failure for search.
302 Fix reading beyond string in yaz_sort_spec.
304 --- 4.2.30 2012/04/11
306 Add two new SRU diagnostics:
307 236: Access to specified database denied
308 1015: Init/AC: Maximum number of simultaneous sessions for Userid
310 Document the very useful ZOOM-C option "apdulog".
312 CQL to RPN: term may be passed through verbatim. This is enabled with
313 truncation.cql . The assumption being that the term is already CQL.
315 --- 4.2.29 2012/03/20
317 record_conv: leader spec may be given for marc element.
318 The leader spec is given as attribute leaderspec for element marc.
319 For example to convert a MARC21 record from MARC-8 to UTF-8:
320 <marc inputformat="marc" outputformat="marc"
321 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
323 record_conv: allow user-XSLT params. For example:
324 <xslt stylesheet="MARC21slim2DC.xsl">
325 <param name="myparameter" value="myvalue"/>
326 <param name="otherparameter" value="othervalue"/>
329 record_conv: fix error handling for missing marc charsets.
331 CQL: fix extra terms in wrong order.
333 --- 4.2.28 2012/03/06
335 record_conv: modify new API for conversion types. The conversion types
336 may be passed in new functions yaz_record_conv_configure_t and
337 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
339 Avoid mixed statement/variable declare; fixes compilation with Visual
342 --- 4.2.27 2012/02/28
344 Add non-standard SRU diagnostic: 235: "Database does not exist".
345 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
346 Update SRU to Bib-1 diagnostic maps accordingly.
348 CCL: add two new diagnostics for unsupported masking. The new
349 diagnostics are: "Embedded truncation not supported" and
350 "Single charcacter mask not supported".
352 --- 4.2.26 2012/02/23
354 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
356 --- 4.2.25 2012/01/11
358 Build YAZ for Ubuntu Oneiric.
360 CCL: allow parantheses for proximity operands. For example CCL query
361 (a) % (b) is now allowed.
363 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
364 marked dead, rather then being destroyed. If not, the session memory is
365 being free'd before the search/scan handler is finished. Also destroy
366 'request' memory in request_release rather than in various places,
367 which resulted in leaks from time to time.
369 --- 4.2.24 2011/12/21
371 cql_sortby_to_sortkeys: honor sort prefix.
373 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
374 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
375 The rpn2cql family of functions now always returns quoted CQL terms.
377 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
379 --- 4.2.23 2011/12/15
381 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
382 sequence is treated as one. For example, &&a=b&&&c& is identical to
385 --- 4.2.22 2011/12/05
387 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
388 APDUs for a connection to a WRBUF.
390 --- 4.2.21 2011/11/23
392 Fix cql_sortby_to_sortkeys. Completely broken before.
394 Make CCL's @truncation work again.
396 --- 4.2.20 2011/11/09
398 New ZOOM connection setting: tproxy. It's like proxy, but does not
399 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
400 to set resolved address + port for a connection outside ZOOM itself.
402 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
404 --- 4.2.19 2011/11/07
406 Fix uninitialized variable in Solr spell support (could cause SEGV
407 for SRU response decoding).
409 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
410 back-end's addinfo through into the ZOOM response addinfo.
412 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
413 they are separated by a colon and a space rather than simply
416 --- 4.2.18 2011/10/28
418 Add support for Solr spell-checking/suggestions through ZOOM.
419 If a Solr target has been configured correctly for spelling-checking
420 and suggestions, these will now be returned on the ResultSet option
421 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
423 --- 4.2.17 2011/09/28
425 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
426 with a flag whether to substitute escape sequences or not.
428 --- 4.2.16 2011/09/22
430 Fix nmem_strsplit_escape to substitute escape char properly.
432 New option for zoomsh -e , which makes it abort on first error and
433 return process exit code to indicate success/failure.
435 YAZ options utility supports special option -- which makes all it treat
436 all following arguments as non-options.
438 --- 4.2.15 2011/09/16
440 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
441 searched if absolute filename is given.
443 Fix conv_xslt() error-reporting when stylesheet is not found.
444 (The value of fullpath is meaningless in this situation.)
446 --- 4.2.14 2011/09/07
448 Fix problem in CQL sort node creation: un-initialized memory.
450 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
451 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
452 CQL sortby depending on whether Type-1 or CQL is actually sent to the
455 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
456 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
458 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
459 will make it possible to use both single-character mask (#) and wildcard (?)
460 in CCL . Throw diagnostic for left truncation because that is not supported
463 --- 4.2.13 2011/09/01
465 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
466 cases using escapes (\-sequences) and masking.
468 PQF parse fix: A trailing backslash followed by end-of-string (\0)
469 would result in a read one byte beyond string.
471 rpn2ccl may use Z39.50 masking for terms (t=z).
473 ICU check fix. Don't include library -lCrun on Solaris, unless present.
475 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
476 not --cppflags (which seeems like an error in icu-config).
478 --- 4.2.12 2011/08/27 RPM package only
480 cql2ccl: fix conversion of terms: operator characters were not
483 --- 4.2.11 2011/08/25 RPM package only
485 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
486 CCL parser will map both # and ? to their regular expression
487 quivalents (. and .*).
489 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
490 of reserved CQL characters.
492 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
493 is, so that they are passed through.
495 --- 4.2.10 2011/08/24
497 ZOOM SRU mode: more aggressive re-connect.
499 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
500 made available as a utility function, declared in <yaz/logrpn.h>
502 rpn2cql_structure() supports proximity nodes (except that the Type-1
503 proximity node's "exclusion" binary is ignored, as there is no way to
504 express that in CQL). Fixes bug #4564.
508 Fix SEGV that could occur if set command of zoomsh was given without
509 value (2nd argument).
511 Fix SEGV that could occur if unsupported transport was given for
512 COMSTACK - say https (when SSL was unavailable).
514 Build yaz-url on Windows too.
518 New utility to get web content. Header is url.h. A command line tool
519 yaz-url is part of the distribution and packages.
521 Fixes for SSL COMSTACK (when gnutls is in use).
523 New functions yaz_base64{encode,decode}. Header is base64.h.
527 ZOOM C includes HTTP response buffer as additional info if it fails
528 to decode the SRU response.
530 Make wrbuf_json_puts available.
534 zoom: throw diagnostic for invalid value for option "sru". Before a
535 bad SRU request was sent.
537 Adding new utility wrbuf_vp_puts.
539 Add cclxmlconfig.obj to win/makefile. It was missing completely.
543 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
544 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
545 redirect was used at the same time.
547 MARC line mode decoding: be less picky about length given - first
548 5 digits of header that is.
550 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
552 Changes to decoding of SRU records: a record with recordPacking=xml is
553 modified with a new root element <yaz_record> if the recordData contains
554 multiple children elements. This is to make the record XML parseable
557 RPN to Solr conversion: encode special characters.
559 Generic Frontend Server: fix uinitialized member, stepSize.
563 Fix a bug in SRU decoding of records.. The database records stored
564 had un-initialized memory, but it would only be seen with yaz_record_render
565 and type_spec="ext" .
567 Fix a bug in ccl_qual_dup introduced in 4.2.3.
571 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
575 Add new utilities to convert from CQL to CCL . These utilities have
576 prefix cql_to_ccl defined in cql.h.
578 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
579 lead to memory heap corruptions when ICU utilities were in use.
583 Make compilation work without Libxml2.
585 yaz-client: remove redundant blanks in display of searchResult-1 term
590 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
591 resulting CQL node (tree) in a new node CQL_NODE_SORT.
593 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
594 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
595 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
596 Note that the CQL sortby spec is only converted when the GFS is already
597 converting from CQL to RPN (cql2rpn element).
599 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
600 specify whether to collapse delimitors or not. The existing nmem_strsplit
601 do collapse (collapse parameter = 1).
603 Windows installer: For NSIS, set InstallDir depending on x86/x64.
605 Rename internal func yaz_use_attribute_create. While non-static, this
606 function is not declared in a public header.
610 Add -lCrun when linking with ICU on Solaris.
612 More quicks character set conversions for OPAC records.
616 fix problem with record_render: records were converted (character set
617 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
621 SRU: add methods for handling DADS SRU-proxy facets.
623 Separate OPAC record character set for ZOOM_record. yaz_record_render
624 allows a character set given as charset=from/opacfrom,to where 'from' is
625 the character set of a bibliographic record, 'opacfrom' is character set
626 of OPAC record and 'to' is the target character set.
630 yaz-client: show may XML format records. Command show followed by 'format'
631 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
634 src/stemmer.c: Avoid using unnamed union. It is not supported by some
637 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
640 Update yaz.spec to operate on both SLES11 / Centos 5.5.
642 RPM: Release includes 'indexdata' name. Use indexdata in release name so
643 this package can be distinguished from other vendors.
645 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
646 as determined by configure
648 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
650 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
651 returns no error and no record, the present request is considered
652 partial (only a subset of the records could be returned by backend), and
653 so it is appropriate to set Present Status to partial-4.
657 Move yaz-config man pages to section 1.
659 More documentation about Solr.
661 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
662 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
663 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
664 peers on some Linux systems. However, in general that does not work
665 so YAZ can not rely on that to work. Debian changed behavior in this
666 respect from Debian lenny to Debian squeeze (still testing as of Oct
668 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
670 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
674 Fix yaz-config output: echo_source not set correctly by configure.
678 Solr Web Service support for yaz-client and ZOOM.
680 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
682 --- 4.0.12 2010/08/17
684 Z39.50 facet support. Facet specifications are passed for search in
685 other-information with ASN.1 as defined in facet.asn and OID
686 .10.1000.81.5 . Facets are expressed as an Attribute list as known
687 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
688 3 is limit (number of entries to get in response). yaz-ztest returns
689 dummy facets if a client asks for them.
691 --- 4.0.11 2010/07/09
693 CCL fixes: bug 2895 and bug 3539.
695 GR1-display: add comma in display - was removed by mistake in
698 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
700 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
702 --- 4.0.10 2010/06/18
704 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
705 result set from a connection. The result set will be on its own
706 thereafter; no operations on it will perform retrievals from a target.
707 Only cached copies are returned.
709 ZOOM C:fix case for HTTP servers responding with Connection:close.
710 Ensure that if there is a current task it is resumed (like fetching
711 more records in a result set) . Bug #3484.
713 PQF parser: use odr_atoi for Odr_int (not atoi)
715 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
716 values that contain any non-digits are treated as string attributes
717 (previously decoding only checked for leading character ([0-9]). PQF
718 encoding: attribute string values are not surrounded by double-quotes.
722 New utility for managing threads - thread_create.h.
724 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
725 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
726 but YAZ' implementation do.
728 Fixes for yaz_cond-functions on Windows 7.
730 DLL export more symbols.
732 zoomsh: show record do NOT render opac.
734 Remove *.la files from Debian and RPM packages.
738 Debian package libyaz-dev depends on libgnutls-dev again (was
739 removed in YAZ 4.0.6, but due to Libtool it is still needed
740 even though yaz-config do not list libgnutls libs).
742 ZOOM: Use only one WRBUF for returning string results for
743 ZOOM_resultset. Reduces memory usage for ZOOM in general.
745 ZOOM: ZOOM_connection do not use a shared pointer to
746 ZOOM_resultset after ZOOM_resultset is destructed by
747 user. Reverts to YAZ 4.0.4 behavior.
751 record-conv: fix problem with at least one XSL conversion -
752 due to probably incorrect usage of XML XSL documents.
756 Fix yaz-config for static mode and the use of SSL (gnutls).
760 Forward decl timeval struct in mutex.h and gettimeofday.h.
762 yaz-config: fix 'static' mode linking.
766 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
767 are wrappers for pthreads or Windows. For Windows these are put in
768 a separate DLL: yaz_cond4.
770 libyaz.la (whole source) is compiled with thread. If thread support
771 is enabled enabled, all source of YAZ is compiled with treading support.
772 This allows core utilities such as yaz_log to use thread facilities.
773 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
774 thread utilities. This commit moves mutex utilities (mutex.c) from
775 libyaz_server.la to libyaz.la.
777 yaz-json-parse displays leading text until error.
781 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
782 patch from Giannis Kosmas.
784 SRU: no longer URL encode SRU database. The URL for an SRU server is
785 a URL and such is alreeady encoded - at least when given with leading
786 http:// or https://. This reverts behavior to YAZ 3.0.50.
788 Support for new MARC XML notation TurboMARC which like MARCXML is a
789 complete representation of MARC/ISO2709.. This one, however, is more
790 compact and allows for faster processing with XSLT. TurboMARC can be
791 used in the marcdisp.h API, from the yaz-marcdump utility and from
794 yaz-ztest can be configured - via the database - to perform certain
795 delays when it performs operations search, present and single record
796 fetch. This allows testers to make yaz-ztest act as a real or even slow
797 Z39.50 server. Refer to the yaz-ztest man pages for details.
801 wrbuf_destroy allows NULL WRBUF passed to it.
803 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
805 Add ZOOM_connection_close.
807 No fixed size buffers for ZOOM shell - bug #3257.
809 tstodr: make it work on s390 platform.
811 New icu iterator-functions. The new icu_iter-functions makes it possible
812 to use ICU chains from many threads.
814 yaz-client: better syntax check for show command.
818 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
821 New simple local-file XML include facility which allows file glob-patterns.
822 Refer to yaz/xml_include.h.
824 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
827 ZOOM_record_get supports new parameter "format" which makes it format XML
830 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
831 JSONText in ECMA-262) is JSONValue, not JSONObject.
835 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
836 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
838 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
839 POSIX/Unix builds .so with major version 4.
841 Remove old LOG_-defines from log.h. They have been obsolete and
842 undefined by default for the last 5 years.
844 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
846 GFS: Remove socket (int *fd) from search_rr handler. The socket
847 descriptor ptr is a facility that allowed a search handler to supply
848 a socket which would serve as a callback - when search was complete.
849 This facility has now been in use for years.
851 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
852 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
853 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
854 returns 'const char *' rather than 'char *. The returned string is
855 read-only and should not be modified by applications. COMSTACK cs_close is
856 now a void function - it no longer returns int. No applications check for
857 the value and the implementations has always returned 0.
859 ZOOM: use size_t for scan hit counts and str size. Functions
860 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
861 occ (hit count) and len (string length) are now of type size_t pointer
862 rather than int pointer. This is to be able to represent large hit counts
863 and to also just to use the proper type for string length (strlen result).
865 New JSON parser. Refer to include/yaz/json.h .
867 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
868 Used to be int in some cases. Many wrbuf_-functions used to return an int
869 indicating some length.. These return values were never used. And so they
872 ODR: odr_malloc, odr_total now takes size_t for size.
874 clone_z_type: fix leak; occurred for encoding failures.
876 --- 3.0.52 2009/12/03
878 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
879 bug was introduced in 3.0.51.
881 --- 3.0.51 2009/12/02
883 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
885 tcpip comstack: fix leak for getaddrinfo.
887 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
888 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
889 Decoding of SRU "path" database is performed by private function
890 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
891 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
893 yaz-client: honor base command for SRU. Change when database setting
894 is applied for SRU and ensure it is kept when a connection is reset.
895 Change also the way errors are displayed or SRU (decoding of packages).
897 --- 3.0.50 2009/11/02
899 Add support for extra request / response data for SRU codecs and GFS.
900 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
901 for extra data response buffer and length. For the GFS, both request
902 and response data (XML) is carried in extra_args and extra_response_data
903 for the search handler. Patch by Ko van der Sloot.
905 ZOOM: For queries that cannot be converted to the specified rpnCharset,
906 ZOOM now returns a diagnostic on the client-side ('invalid query' /
907 10010). This fixes bug #2113.
909 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
910 cmdfile included a 'quit' command that would result in a memory violation.
912 --- 3.0.49 2009/10/01
914 Make a number of functions defined in xmlquery.c static. These have
915 never been declared in a public header file (yaz/xmlquery.h) and was
916 made public by mistake.
918 Improve speed of character conversions (iconv utilities). This makes
919 conversions from MARC-8 faster.
921 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
922 unless type desired is "raw". This will prevent type "xml" from
923 returning ISO2709 .. Which obviously can not be XML parsed.
925 Fix memory leak in ZOOM that would occur if option apdulog was used
926 on a re-used connection.
928 Frontend server logs HTTP requests.
930 Frontend server now sends Z39.50 close when it times out (sesssion has
931 been idle for too long). Versions 2.0.30 and earlier also sent close.
932 But due to a mistake this was disabled in all versions after that, i.e.
933 the server would just close the socket immediately.
935 yaz-client emits a better message when receiving an unrecognised
936 userInformationField.
938 Skip zero-length subfields when decoding ISO2709. This rare case happens
939 if a record has two FS characters in a sequence. Without this patch
940 there would be a reference beyond char array in using_code_len fragments
943 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
945 --- 3.0.48 2009/08/28
947 The show command offered by the zoomsh command now takes a 3d optional
948 parameter type which is what is passed to ZOOM_record. If the type
949 argument is omitted, "render" is used.
951 RPN to CQL conv may use USE string attributes (bug #2978).
953 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
955 --- 3.0.47 2009/07/08
957 Function yaz_xml2query allows a diagnostic element in the PQF XML
958 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
959 code and additional info respectively.
961 The BER BOOLEAN is now the integral type Odr_bool which still happens
962 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
963 typedef'd to Odr_int. This is still an integral 'int', but it may be
964 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
965 ASN-1 compiler as well as programs has been updated to use the new types.
967 --- 3.0.46 2009/06/08
969 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
970 only the bibliographic record was rendered. For type=opac, an OPAC
971 record is only returned if it is present.
973 iconv: small fix for encoding of advancegreek.
975 yaz-client: avoid double display of SRU/SRW records (bug #2798).
977 yaz-client: option auto_reconnect=on really reconnects.
979 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
981 server: avoid null ptr ref for for yaz_poll errors.
983 build: fix RPM build for RHEL 5.3.
985 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
987 --- 3.0.45 2009/03/31
989 Fixed bug #2709: TCP connect returns Invalid argument.
991 Fixed compilation for mingw.
993 Honor charset for raw records (ZOOM_record_get).
995 Fixed use of errno for threaded mode that was seen on Solaris 10.
997 Fixed argument passing with blanks in value for Windows Service.
999 Disable YAZ' own log rotate by default (no 1 GB limit).
1000 The variable l_max_size which specifies the log file limit is set to 0
1001 (DISABLED): This is due to the fact that YAZ is most often deployed using
1002 logrotate. Also YAZ can not perform log rotate because of unsufficient
1003 permissions (setuid).
1005 --- 3.0.44 2009/02/17
1007 List supported encodings in man page for yaz-iconv.
1009 Fixed missing SSL libs for --libs output
1011 Re-established OID record syntax application-xml. Nobody should use it
1012 but we don't want to change soname because of this symbol being absent.
1014 --- 3.0.42 2009/02/02
1016 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1018 Added member named_result_sets for init handler struct for the GFS. This
1019 allows a server to disable named result sets.
1021 Removed OID record syntax application-xml.
1023 Added support for rule-based transliterator for ICU wrapper of YAZ.
1025 Fixed bug #1902: yaz-icu XML output.
1027 Make YAZ checks Emacs friendly.
1029 BITSTRING value shows value. Bug #2346.
1031 ISO2709 decoding: skip control characters from indicator data.
1033 Omit sort key by default in yaz-icu's output.
1035 Allow combined single char options (again) for YAZ' options function.
1037 Utility yaz-marcdump got option to display YAZ version (-V).
1039 Allow YAZ to use ICU 3.4.
1041 Added new ICU test case which illustrates removal of diacritics.
1043 --- 3.0.41 2008/12/29
1045 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1047 --- 3.0.40 2008/12/29
1049 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1052 Fixed bug #2352: yaz-marcdump crashes for certain record.
1054 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1056 Added support for Danmarc2 to UTF-8 conversion.
1058 Added support for ISO5426 to UTF-8 conversion.
1060 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1061 implementation version.
1063 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1065 --- 3.0.38 2008/11/10
1067 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1068 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1070 ZOOM C now interprets databaseName option for ZOOM connection as path
1073 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1075 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1077 Dummy Libxml2 types no longer defined in headers of YAZ'.
1079 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1082 --- 3.0.36 2008/09/26
1084 Various ODR chapter fixes.
1086 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1088 Added missing source for Windows compilation, mutex.c.
1090 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1092 For SRU connections in ZOOM all records up to "count" are now fetched.
1094 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1095 in Windows due to bad error handling for Libxml2.
1097 Added facility for sending arbitrary records (ASN.1 any) using
1098 ZOOM C's Extended service update. Patch by Sam Reynolds.
1100 New options for ZOOM C's connection, logapdu which makes ZOOM log
1103 --- 3.0.34 2008/06/18
1105 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1107 --- 3.0.32 2008/06/12
1109 Fixed memory violation that could occur when decoding UTF-8. This bug
1110 was only present in 3.0.30 of YAZ.
1112 --- 3.0.30 2008/06/06
1114 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1115 GNU TLS is used by default (if found).
1117 yaz-ztest returns OPAC records if a client asks for OPAC.
1119 Improved speed of MARC-8 encoding.
1121 Added support for lossy and loss-less MARC-8 encoding.
1123 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1125 Added new Windows Service wrapper (sc).
1127 yaz-client's itemorder command may now send a file.
1129 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1131 Added new function yaz_log_xml_errors.
1133 Allow (but warn) unknown XML attributes in MARCXML parsing.
1135 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1137 The UTF-8 to MARC-8 conversion now uses a different set of characters
1138 for Greek symbols. Bug #2120.
1140 --- 3.0.26 2008/02/21
1142 Added yaz_daemon (daemon.h).
1144 Fixed bug #2068: pkg-config trouble
1146 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1148 --- 3.0.24 2008/01/28
1150 Document --with-xml2 option.
1152 Added OPAC XML XSD (etc/opacxml.xsd).
1154 Allow glob mask for name attribute in retrieval element for the
1155 generic frontend server's retrieval facility.
1157 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1158 except POLLIN/POLLOUT.
1160 Fixed error handling in cs_listen. Bug #2037.
1162 --- 3.0.22 2008/01/20
1164 Fixed version in yaz/yaz-version.h.
1166 Fixed bug #2027: Crash when closing connection.
1168 Changed configure so that ICU support is only enabled if only ICU
1169 and Libxml2 is available (because the ICU chain is XML based).
1171 --- 3.0.20 2008/01/15
1173 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1174 is built. Only this DLL depends on the ICU runtime.
1176 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1177 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1179 Changed license of CCL module to 'Revised BSD'. After consultation with
1180 remaining members of the original EUROPAGATE consortium, we are re-issuing
1181 the CCL module without a separate license. The software was developed by
1182 Index Data as part of a research project. The special license was included
1183 to help feed usage information back to the project consortium to support
1184 project evaluation. At this time, the project consortium has long-since
1185 disbanded, and the majority of the original principals have retired. At the
1186 same time, we have significantly modified the software during the following
1187 years, to the point where very practically no original code remains. To
1188 simplify re-use of the software, we have contacted those members of the
1189 consortium who could be reached, and agreed to re-issue the module as a
1190 proper part of the YAZ package.
1192 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1194 CQL closer to being version 1.2 compliant. CQL also allows free-form
1195 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1198 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1199 bug could make Extended services handling crash in the ZOOM layer. This
1200 bug was only present in YAZ 3.0.18.
1202 --- 3.0.18 2007/12/19
1204 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1207 yaz-marcdump reads and writes collection wrapped records.
1209 Handle OPAC for record conversion module.
1211 Fixes for ICU wrapper.
1213 Allow ICU libs to be controlled with --with-icu .
1215 --- 3.0.16 2007/11/12
1217 Added yaz_poll which is a wrapper for select/poll. When poll is available
1218 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1219 sockets to be in use.
1221 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1222 functionality through an XML based configuration (ICU chain). This system
1223 is useful for search facilities such as Pazpar2 and Zebra that needs to
1224 perform tokenization of indexed material. The ICU code in a separate
1225 library libyaz3_icu.a.
1227 Added HTTP tunnel facility for COMSTACK, bug #1752.
1228 This is a facility that allows a Web proxy, such as squid, to tunnel
1229 Z39.50 traffic. This facility is "transparent" to must applications
1230 using YAZ. It's enabled by using pseudo transport connect: followed by
1231 the proxy address, followed by command, then follwed by he regular
1232 "virtual" addresss. For example,
1233 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1235 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1237 --- 3.0.14 2007/09/21
1239 Fixed bad memory reference in ZOOM_record - cuased by member not being
1240 initialized. This was a problem only in YAZ 3.0.12.
1242 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1243 fields were not removed.
1245 Changed the way C code is generated from codetables.xml. Made a MARC-8
1246 conversion trie for each characterSet section rather than codeTable.
1247 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1248 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1250 --- 3.0.12 2007/09/12
1252 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1253 from ZOOM_record_error).
1255 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1257 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1259 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1261 Better SRW-to-Bib-1 diagnostic mapping.
1263 ZOOM C and yaz-client announces SRU version 1.2 by default.
1265 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1268 Fixed in yaz_sru_decode to allow other version than 1.1.
1270 --- 3.0.10 2007/08/22
1272 Added support for SRU scan for ZOOM.
1274 Added support for the use of the older versions or Extended Service
1275 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1276 set to the version , 1=first, 2=second, 3=third. The third version is
1277 what ZOOM C has used so far. And that, obviously, is the default.
1279 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1280 therefore in Zebra and in SimpleServer-based applications). The new
1281 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1282 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1283 which is passed into the back-end search callback function.
1285 Added support for HTTP Basic authentication in clients: the SRU/W
1286 codec encodes the username/password elements of the PDU structure
1287 appropriately, and these may be set using the "user" and "password"
1288 options in ZOOM-C applications (the same options that are used for
1289 Z39.50 authentication).
1291 --- 3.0.8 2007/06/25
1293 Fixed bug #1208: SSL appears to be broken in ZOOM.
1295 Fixed bug #1206: Libxml2 include path weirdness.
1297 Added oid_name_to_dotstring.
1299 Allow elementSetName to be specified for ZOOM C record update.
1301 Allow waitAction to be specified for ZOOM C based for Extended Services.
1303 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1304 syntax OID. Bug introduced in YAZ 3 series.
1306 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1308 --- 3.0.6 2007/06/06
1310 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1311 directory. yaz-client now reads commands from file given by option -f
1312 if specified; then tries to read .yazclientrc in current directory.
1313 Failing that, it reads .yazclientrc from user's home directory.
1315 Added support for correlationInfo Note and ID for Record Update via
1318 Added yaz-client command querycharset which specifies character set for
1319 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1320 (termListAndStartPoint).
1322 Charset ISO5428:1984 is an alias for ISO5428-1984.
1324 Implemented a way to perform scan in a result set using Z39.50. This
1325 is achieved by attaching the result set name in the characterInfo
1326 (type InternationalString) of OtherInformation in the Scan Request PDU.
1327 The result set is identified in the otherinformation by the new OID:
1328 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1329 This allows for scan in result set and faceted search . Zebra did some
1330 of this in the APT term using attribute type 8 and value being result
1331 set. Using the OtherInformation approach for this is cleaner and easier
1332 to work with in proxies and the like. This facility can be used in
1333 yaz-client using new command setscan which takes a result set as first
1334 argument, start position (APT) as second.
1336 Changed decoding of SRU XML packed records to deal with servers that
1337 have recordData with XML data with multiple root nodes. Also make
1338 comparison for recordPacking case insensitive. Again, one server
1339 returns "XML" where others return "xml".
1341 For SRU responses allow Content-Type application/xml as well as text/xml.
1343 --- 3.0.4 2007/05/21
1345 Fixed bug in character set conversion of BER strings. Bug introduced
1348 --- 3.0.2 2007/05/08
1350 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1352 For OID class, use oid_class consistently.
1354 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1357 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1358 character set for bibliographic information interchange". By Giannis Kosmas.
1360 Added documentation on new OID API.
1362 --- 3.0.0 2007/05/02
1364 Changes to generic frontend server interface: added new member
1365 'query_charset' for bend_initrequest structure. A backend init handler
1366 should set this member to its native character set for query terms.
1367 When defined, the frontend server logic will announce this character set
1368 to a client if the negotiationModel bit is set by the client. All server
1369 implementors are encouraged to specify this. If a backend server does not
1370 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1372 Added CCL utility to remove terms (stop words) from resulting RPN
1373 tree. This is handled by functions with prefix ccl_stop_words_ .
1375 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1376 terms in RPN queries.
1378 Clean-up the CCL API. Moved some internal structures from ccl.h to
1379 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1380 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1381 This is replaced by ccl_parser_find_str which takes a string instead.
1383 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1384 libyaz.la is the core of YAZ except the generic frontend server and
1385 does not depend on POSIX threads anymore. libyaz_server.la is the
1386 generic frontend server facilities and uses POSIX thread functionality
1387 if available. The libyaz.la no longer depends on POSIX threads because
1388 the number of global structures is limited. NMEM no longer re-uses blocks
1389 between threads ; it simply free's memory immediately but allocates in
1390 "large" chunks as usual. We don't expect any performance penalties
1391 because of this. The yaz_log system is still using a global log_level so
1392 caution must be taken when modifying it with yaz_log_init_.. +
1393 yaz_log_mask_str. This, however, should not cause any trouble because
1394 these functions are called during initialization of application code
1395 anyway. `yaz-config --libs server` returns libs for server applications;
1396 `yaz-config --libs` returns libs for non-server applications.
1398 New OID database - with public definitions in oid_db.h. Removed old OID
1399 database including the head oid.h and definitions such as enum oid_value
1400 and struct oident. The new OID database uses the same string names as
1401 before but the 'protocol' is gone. There are now only two representations
1402 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1403 converts from string to OID; functions with prefix yaz_oid_to_string
1404 converts the other way.
1406 Change to emit_term() in CQL-to-PQF query translation: when a term has
1407 the /regexp relation modifier, do not process it for leading and
1408 trailing "^" and "*", which have quite different meanings in regular
1411 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1412 write handlers no longer carries a 'last' parameter. This will make
1413 yaz_iconv flush "less" characters. A flush is performed by call to
1414 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1416 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1417 removed, because function yaz_query_to_wrbuf does the same.
1419 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1420 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1422 Deprecated MARC utility functions removed.
1424 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1427 Branch split: YAZ_2_1_55_branch
1429 --- 2.1.54 2007/03/16
1431 Fix to ZOOM-C so that transparent reconnection is properly handled on
1432 connections that are in asynchronous mode.
1434 Fixed compilation on OpenBSD 4.0.
1436 Large strings in GRS-1 records are now properly displayed in yaz-client.
1438 Added character conversion support for "advancegreek"; based on patch from
1441 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1442 sequence is met. Before the error was not set so it would be unknown.
1444 Adjust yaz-marcdump MARC reader so that it skips until record separator
1447 --- 2.1.52 2007/03/07
1449 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1450 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1451 fd_set structure used as a bitmask for the FDs to be selected on.
1453 Using ACX_PTHREAD macro to check for POSIX threads.
1455 Fixed have-vsnprintf check.
1457 --- 2.1.50 2007/02/23
1459 Fixes for configure on BSD. Bug #900.
1461 Added snprintf/vsnprintf wrappers for systems that don't have
1462 limits (heavens forbid).
1464 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1465 created before all previous tasks were completed and removed from the
1466 task queue, the new task could be removed by a mistake.
1468 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1470 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1472 Fixed bug #832: Problem with MARC/charset in yaz-client.
1474 Fixed bug #668: save command line history for yaz-client.
1476 Fixed bug #830: pkg-config support.
1478 --- 2.1.48 2007/01/23
1480 Extended ZOOM result set options with two options that may be read by
1481 a client: resultSetStatus and presentStatus with values as specified for
1483 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1485 Fixed bug #827: Using SSL fails on Debian etch.
1487 Fixed bug #826: Weird looking chars for set of MARC records.
1489 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1490 that is treated as an ItemOrder with itemRequest being an XML document
1491 external. The value of "doc" is the content.
1493 Extended the GFS search facility. New member of bend_search_rr
1494 'estimated_hit_count' signals that hits is known to be an estmate
1495 (higher or lower than real hit count). New member 'partial_resultset'
1496 signals that the search was partial (hit count is lower or equal than
1497 real hit count). For Z39.50, the information is stored in resultSetStatus
1498 member of SearchResponse APDU. For SRU, the information is signalled
1499 via SRU diagnostic 59: "Result set created with valid partial results
1502 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1504 --- 2.1.46 2007/01/13
1506 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1508 Added ZOOM_connection_peek_event.
1510 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1511 the following new functions:
1512 ZOOM_event_nonblock, ZOOM_connection_process,
1513 ZOOM_connection_get_{socket,mask,timeout},
1514 ZOOM_connection_fire_event_{timeout,socket}.
1515 The existing blocking event handler, ZOOM_event, is a wrapper for the
1516 + blocking ZOOM_event_sys_{poll,select}.
1518 Implemented function ccl_xml_config which parses XML version of CCL
1519 configuration (bug #798).
1521 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1523 Added timings utility (yaz/timing.h)
1525 --- 2.1.44 2007/01/03
1527 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1530 Fixed bug #779: Rotation of apdu.log fails.
1532 Fixed for character set conversions:
1533 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1534 Honor G1 set in MARC-8 decoding.
1536 --- 2.1.42 2006/12/17
1538 Fixed bug #775: char conversion does not handle Alternative UTF-8
1541 Implemented function yaz_marc_read_line which parses MARC line format
1542 records. There is a wealth of formats out there. So far, this function
1543 reads line records produced by yaz_marc_write_line.
1545 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1546 more generic and easier to remember(!) options: -i format and -o format
1547 which specifies input format and output format respectively - where
1548 format is one of "marc", "marcxml", "line", "marcxchange".
1550 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1551 does not print anything except warnings for records.
1553 For yaz-marcdump, added support for MARC split into files (-s) with a given
1556 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1557 spec, at http://www.loc.gov/standards/sru/record-update/
1558 This has changed the binary layout of the following structs:
1559 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1560 bend_update_rr . Patch by Ko van der Sloot.
1562 Added GFS utility function bend_assoc_is_alive which returns 1 if
1563 association is still alive (client is connected); 0 otherwise (client
1564 closed connection). This allows busy servers to stop working for
1567 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1568 been a separate piece of software. This version of ziffy has been modified
1569 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1571 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1573 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1574 Client code may now interrogate options such as "init_opt_sort" to
1575 find out whether the server claims to support various options.
1577 --- 2.1.40 2006/11/27
1579 Added utilities yaz_{set,get}_esn to set/get element set name from
1582 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1583 of YAZ and has been so since YAZ 2.1.10.
1585 Implemented ZOOM_record_error which returns error information for
1586 record (surrogate diagnostic).
1588 --- 2.1.38 2006/10/31
1590 Updates for SRU Update by Ko van der Sloot:
1591 1. Changed name from "operation" to "action"
1592 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1593 versions in the code, marked as 'backward compatible'.
1594 3. Added diagnostics for SRU Update.
1596 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1598 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1600 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1602 For GFS, fixed problem with SRU diagnostic 'First record position out of
1603 range' being issued for 0 hits.
1605 zoomtst10 part of Windows Build.
1607 --- 2.1.36 2006/10/13
1609 Implemented yaz_filepath_comp which splits a path into file path
1610 components (required by Zebra 2.0.3+).
1612 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1613 BSD inspired license until now so this should not have any real impact on
1614 anybody. See http://www.opensource.org/licenses/bsd-license.php
1616 Fixed bug #687: Missing log lines.
1618 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1621 Fixed bug #689: SRU diagnostics to be added.
1623 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1624 whether a connection is idle (no more work do do).
1626 --- 2.1.34 2006/10/04
1628 Change type of optval from long to int for invocation of setsockopt with
1629 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1631 Added support for specifying the max log file size for the Generic
1632 Frontend Server. The size is given with option -r.
1634 --- 2.1.32 2006/09/21
1636 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1638 --- 2.1.30 2006/09/17
1640 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1643 Fixed bug in Generic Frontend Server that could cause a server to stop
1644 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1646 For the generic frontend server, the maximum record size is used as maximum
1647 size of incoming packages (SRU + Z39.50). The value until was previously
1648 only used in Z39.50 Init negotiation and, later, in a session controlled
1649 sizes of records returned. This is controlled using -k option. It can be
1650 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1652 --- 2.1.28 2006/09/04
1654 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1657 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1659 New option for yaz-marcdump -lpos=value which allows setting a portion
1660 of MARC header to a certain value.
1662 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1664 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1665 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1667 --- 2.1.26 2006/08/15
1669 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1672 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1674 --- 2.1.24 2006/08/08
1676 Fixed MARC ISO2709 encoding routines to deal with character set
1679 Minor changes to GFS logging. Database included in search request log
1682 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1683 cached/multiple records.
1685 Shared libraries are built by default on Unix+configure.
1687 Changed cql2pqf transformation to use a different evaluation order. The
1688 new order is: always, relation, structure, position, truncation, index
1689 and relationModifier. Old order was: always, relation, relationModifier,
1690 structure, index, position, truncation. Note that the the latter ones
1691 override former ones for identical attributes.. The new scheme means that
1692 it is possible to override any existing attribute with a relationModifier.
1693 And also that it is possible to override everything for the index rule
1694 (except the ones listed in relationModifier). No order is perfect but this
1695 one, we believe, covers more real cases.. The "always" should have been
1696 called "default", since the attributes there can be overridden with all
1699 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1700 compilation phase, but also for yaz-config --cflags output. This allows
1701 us to have public headers with Libxml2 stuff in them . It should also,
1702 eventually, make Libxml2 checks redundant in packages using YAZ, such
1705 --- 2.1.22 2006/06/15
1707 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1708 stored in uri, message and details.. Previously diagnostics were stored
1709 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1710 compatibility.. but he's probably the only one affected, so.
1712 Added support for CCL, compiled on the client side, in ZOOM-C. This
1713 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1714 input; the resulting query objects can be used for for searching with
1715 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1717 YAZ' configure searches for OpenSSL by default.
1719 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1720 SL_CTX_use_certificate_file. See
1721 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1722 for more info. Thanks to Ko van der Sloot.
1724 --- 2.1.20 2006/06/02
1726 Bug #600: SRU GET, POST support for yaz-client. Introduced
1727 command 'sru' which selects method SOAP/GET/POST.
1729 Allow missingValueAction to be specified for the sortspec string -
1730 function yaz_sort_spec. By default, the missing value action is null.
1731 Use ! to specify "abort". Use = followed by stringvalue to specify default
1734 Ensured that Present-handler (if defined) is called in GFS before any call to
1735 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1736 searchRetrieve requests.
1738 Documentation for YAZ is now based on the Docbook XML/XSLT using
1739 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1740 is no longer depending on jade/openjade or docbook-to-man scripts.
1741 PDF is no longer part of the distribution - but can optionally be
1742 made using DSSSL/jadetex or FOP.
1744 Added retrieval handling support in Generic Frontend Server to support
1745 conversion between MARC/XML as well as XSLTtransforms. See
1746 etc/yazgfs.xml for an example.
1748 Added Authentication support to Generic Frontend Server in SRU
1749 mode. Authentication using HTTP Basic is supported, as is the use
1750 of 'x-username' and 'x-password' parameters in the request itself.
1752 Added support for a new character set MARC8s identical to MARC8 except
1753 that it converts combined characters to single Unicode characters in the
1754 Latin-1 range (when possible).
1756 --- 2.1.18 2006/04/24
1758 ASN.1 compiler 0.4: generates brief Doxygen file header for
1759 generated .h/.c files.
1761 Utility yaz_iconv now supports conversion to MARC-8.
1763 New facilities for the MARC module. The reading - and writing of
1764 content are separate methods for the yaz_marc_t handle. The following
1765 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1766 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1767 format). Write functions have prefix yaz_marc_write_.. The existing
1768 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1769 available. Removed support for OAI-MARC and simplexml (not the
1770 simplexml from PHP5).
1772 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1773 to be returned for this connection.
1775 --- 2.1.16 2006/03/31
1777 Allow multiple languages and charsets to be specified with
1778 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1779 negcharset iso-8859-1,utf-8
1781 Translation of proximity nodes from CQL into PQF now works.
1783 Moved to automake 1.8, 1.9.
1785 Added function yaz_log_set_handler which allows a log handler to be
1786 installed. This handler will be called for all log messages. Output
1787 to file is also produced; but that can be disabled by passing NULL
1788 fname to yaz_log_init_file.
1790 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1792 For SRW (including GFS), accept application/soap+xml as content-type
1795 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1796 produces NO stylesheet reference even if a default stylesheet is specified
1799 --- 2.1.14 2006/03/14
1801 Updated Windows package to include yazd.dll + yazd.lib for the
1802 Development component.
1804 If the environment variable YAZ_LOG is set, then it is used as a
1805 string indicating the default level of logging to use if not
1806 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1807 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1808 used as before. So, for example, to omit warnings from YAZ logging,
1809 export YAZ_LOG=-warn
1811 cql_transform() now map structure and other attributes before indexes,
1812 so that index-specific structures and other attributes can override
1813 defaults. So now a combination of mapping specifications such as:
1815 index.dc.date = 1=date-modified 4=5
1816 does the right thing.
1818 cql_transform() now also respects the "always" mapping specification,
1819 which establishes an initial set of attributes to be used for all
1820 terms except where overridden by more specific attributes associated
1821 with the index, relation or modifier.
1823 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1824 which mode to use; one of "post", "get" or "soap" (SRW, default).
1826 Fixes for yaz_iconv routines: changed trie-based character set conversions
1827 to use only non-negative values for bit fields due to Sun's C compiler not
1828 supporting negative values.
1830 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1831 sequences where not read correctly. Fix by Rustam Usmanov.
1833 Updated win/makefile to use options, settings which makes things
1834 compile with VS C 2005.
1836 --- 2.1.12 2006/02/01
1838 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1840 In ZOOM socket code, use select instead of poll on MacOSX.
1842 ZOOM-C now support client-side compilation of CQL into RPN that is
1843 sent to the server, enabling CQL to be used against all Z39.50
1844 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1845 ZOOM_query object, and submit it using ZOOM_connection_search().
1846 The CQL-to-RPN translation uses a configuration file, the name of
1847 which must be specified in the Connection's "cqlfile" option.
1849 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1850 function, which takes as its start-term parameter a ZOOM_query object
1851 (which may have had either CQL or RPN set into it).
1854 --- 2.1.10 2005/11/29
1856 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1857 GFS to support this as well. Backend handler, bend_srw_update, does the
1858 update work. Code contributed by Ko van der Sloot.
1860 Allow retrieval of Search Result-1 information in ZOOM by the use of
1861 options that are attached to a result set. ZOOM documentation updated
1864 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1865 UTF-8 conversion. Patch by Raj Patel.
1867 Added option -m to GFS to control formatting of timestamps in log file.
1869 Added 'exit' as synonym for 'quit' in yaz-client
1871 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1872 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1873 for the new members. Patch by Ko van der Sloot.
1875 Added support for SRU POST. It is supported for content-type
1876 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1878 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1879 Instead make the library libyaz.la multi-threaded. Threading as a whole
1880 can still be disabled by configure option --disable-threads. Previosly,
1881 with older GLIBCs there were problems with MT libs under Apache. This
1882 has now been fixed a long time ago.
1884 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1887 CQL module modified to be case insensitive for relations/indexes/operations.
1889 Fixed bug in CQL transform code: incorrect value relationModifieder
1892 Added 'show all' command for yaz-client which retrieves all results
1895 Added new yaz-client, xmles, which takes a (private) OID and
1896 a document to be sent as an extended service request.
1898 Describe new yaz-client commands wait_response and set_auto_wait.
1900 Increase TCP/IP listener backlog from 3 (which I am guessing was
1901 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1902 that the socket will queue as many incoming connections as it's able
1903 to handle ongoing connections. In other words, it will never now
1904 refuse a connection that it would be able to handle merely because
1905 it's not got around to accepting() enough of the pending connections
1906 yet. This is the behaviour anyway under Linux, where the listen()
1907 argument is ignored; but not under BSD and on systems such as
1908 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1909 YAZ-based servers should now be uniform across operating systems in
1912 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1913 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1914 This allows yaz-marcdump to read large MARC batches (>2 GB).
1916 Modified all YAZ source files - except the source which is auto-generated
1917 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1920 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1921 corresponding to the existing *_setl() function. These allow option
1922 values containing arbitrary valuues.
1924 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1925 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1926 except that it returns an indicator of whether or not the sort
1927 criterion was accepted (0 for OK, -1 for invalid).
1929 --- 2.1.8 2005/06/07
1931 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1932 MARC output rather than returning "new" buffer.
1934 yaz-client warns about unknown init options.
1936 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1938 --- 2.1.6 2005/05/24
1940 Added support for SRW sort in Generic Frontend Server. Patch
1941 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1942 sortKeys - or NULL if none is provided.
1944 Fixed bug #307: It was impossible to specify indefinite/no timeout
1945 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1948 Added support for multiple languages and charsets to be specified in
1949 ZOOM. Each charset/language is separated by a blank. If negotiation is
1950 in effect in init-response, Option
1951 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1952 Code based on patch by Vasiliy Osadchuk.
1954 Fixed bug #306: infinite recursion that occurred when calling
1955 yaz_log_level_init as the first call (before other log level or
1958 Fixed bug in scan handling in front end server: if preferred-Position-In-
1959 Response was non-present, a NULL pointer referece was performed.
1961 --- 2.1.4 2005/04/26
1963 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1964 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1965 now defined for all those error codes. So instead of putting 109 in
1966 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1967 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1969 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1972 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1974 Program yaz-client now exits and produces an error message if multiple
1975 Z39.50 servers are specified on the command line (none or one allowed
1978 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1981 --- 2.1.2 2005/03/16
1983 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1985 Fixed bug #272: Preserve spacing for CCL terms.
1987 --- 2.1.0 2005/03/14
1989 Added support for virtual hosts and multiple backend servers for
1990 the YAZ frontend server. The configution is XML based and
1991 support specificition of CQL to RPN mappings and explain information.
1992 See section "Virtual Hosts" in the YAZ manual.
1994 Extended OPAC display utility. OPAC display utility renders
1995 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1996 to supplement yaz_marc_decode_wrbuf.
1998 Fixed a bug in MARC decoder that could caused it to crash for some
1999 invalid MARC records. More diagnostics and warnings where added in
2000 XML output (warnings, etc are stored in comments).
2002 --- 2.0.34 2005/02/08
2004 Fixes for UNIX domain sockets. Bug #261.
2006 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2008 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2009 Added yaz_marc_subfield_str which defines subfield lead string which is
2010 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2011 yaz_marc_endline_str which defines end of fields string used in
2012 YAZ_MARC_LINE format. Default string is newline.
2014 Experimental support for MarcXChange. This format can be produced
2015 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2016 http://www.bs.dk/standards/MarcXchange.xsd
2018 Added yaz-client commands scansize that sets maximum number of
2019 entries to be returned by scan.
2021 --- 2.0.32 2005/01/11
2023 Added support for SRW scan in yaz-client and Generic Frontend Server.
2025 * Added whereInList member to SRW Scan Term.
2027 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2029 Fixed NMEM system to return aligned blocks on the smallest boundaries
2030 that are suitably aligned for all possible types on the particular
2031 architecture YAZ is being built for.
2033 --- 2.0.30 2005/01/04
2035 Fixed numerious warnings that was issued with newer versions of GCC.
2037 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2038 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2041 Make YAZ Generic Frontend Server slightly faster.
2043 Enhance (and reduce) logging for Generic Frontend Server.
2045 Revert YAZ log system so that it flushes every write operation
2046 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2048 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2049 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2050 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2051 will effectively disable old definitions.
2053 --- 2.0.28 2004/11/09
2055 Added yaz_log_time_format which specifies log format using
2058 Added yaz_log_module_level which returns mask for a module. Value
2059 is non-zero mask a if module is enabled; zero if disabled.
2061 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2062 in include/yaz/cql.h.
2064 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2066 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2068 Fixed bug #172: RPM builds does not enable SSL.
2070 Doxyfile.in part of dist. Doxyfile generated by configure.
2072 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2073 are given and the corresponding component does not exist.
2075 Extend CCL documentation in YAZ reference. Describe r=r.
2077 --- 2.0.26 2004/10/01
2079 Fixed MARC->MARCXML conversion to properly deal with
2080 fields, subfields, indicators having non-ASCII characters.
2082 Fixed MARC->MARCXML conversion so that ASCII control characters
2083 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2086 Added YAZ GFS support for conversion from Z39.50 surrogate
2087 diagnostics to SRW surrogate diagnostics.
2089 Bug fix: YAZ GFS did not return schema in explainResponse.
2091 --- 2.0.25 2004/09/30
2093 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2094 now converts recordSchema to elementSetName as well as schema URI.
2096 Fixed bug in COMSTACK that prevented HTTP request packages from being
2099 --- 2.0.24 2004/09/29
2101 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2102 does not require white-space before and after the dash in a range, e.g.
2103 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2106 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2107 due to new GCC removing "redundant" code.
2109 Added yaz-client commands scanpos and scanstep that sets preferred
2110 position and step-size for scan.
2112 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2114 Added CCL utility ccl_qual_buf which parses one or more CCL
2115 spec lines in a buffer.
2117 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2118 of name and value - ignoring empty lines and comments.
2120 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2122 Added odr_get_element_path which returns current element path for an
2123 ODR handle. This utility is useful in error handling or user-defined
2126 Added ODR_PRINT utility odr_set_stream which is is a more generic
2127 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2128 to a write function and pointer to close function. The close function - if
2129 non-NULL - will be called during odr_destroy.
2131 Fixed bug in CCL parser where truncation char was not removed from
2132 right side when truncation=both was in effect.
2134 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2137 --- 2.0.23 2004/08/11
2139 Fix buffer overrun in CQL parser when dealing with proximity (%).
2141 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2142 to UTF-8/UCS conversion is now only based on codetables.xml.
2144 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2146 --- 2.0.22 2004/08/06
2148 Add support for more "commit changes" in ZOOM (uses Extended Services).
2150 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2153 Yet another small fix for configure of SSL.
2155 --- 2.0.21 2004/05/14
2157 Fix SSL libs for configure when --with-openssl=DIR is given.
2159 --- 2.0.20 2004/05/10
2161 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2163 SSL comstack now uses yaz.pem certificate file on server side
2164 by default. Certificate filename can be configured by calling
2165 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2167 Fix bug regarding multiple calls to ZOOM_connection_connect.
2169 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2171 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2172 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2174 ZOOM now allows inspection of X509 peer certificate for verification.
2175 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2177 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2178 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2179 as "modular" but it simplifies things.
2181 Added cs_get_peer_certificate to that returns peer X509 PEM.
2183 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2184 NULL if SSL is unavailable.
2186 Documentation about MARC decoding tools.
2188 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2190 --- 2.0.19 2004/03/30
2192 Rename CHANGELOG to NEWS to follow GNU style packing.
2194 Fix bug with missing initialization of member in init_diagnostics.
2195 This bug affects threaded version of GFS server.
2197 --- 2.0.18 2004/03/20
2199 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2202 Ensure zlib.dll is packed with Windows install.
2204 --- 2.0.17 2004/03/17
2206 Fix encoding of xsd:string to use text instead of CDATA.
2208 Fix endless loop in CQL parser with unbalanced ".
2210 Use a more compact way to store MARC-8 conversion tables.
2212 --- 2.0.16 2004/03/16 Debian only
2214 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2217 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2222 --- 2.0.15 2004/03/01
2224 Another fix for decoding of XML packed records.
2226 --- 2.0.14 2004/02/25
2228 Fixes for Chunked encoding. White space not ignored after length spec.
2230 Update NS and use default NS for SRW diagnostic elements.
2232 --- 2.0.13 2004/02/23
2234 Implement ZOOM_resultset_cache_reset which resets record cache.
2236 Implement ZOOM_resultset_sort which sorts a result set.
2238 Implement chunked HTTP transfer.
2240 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2242 --- 2.0.12 2004/02/16
2244 Added member 'schema' to bend_explain_rr structure so that backend
2245 can specify explain record identifier. Defaults to Zeerex 2.0.
2247 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2249 --- 2.0.11 2004/02/16
2251 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2254 Added init command for yaz-client which sends "extra" init request.
2256 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2257 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2259 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2261 Make ZOOM error code for "invalid query".
2263 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2265 --- 2.0.10 2004/02/05
2267 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2270 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2272 Added option -p <file> to make Generic Frontend Server to write PID file.
2274 Added option -D to put Generic Frontend Server in background on its own.
2276 Make ZOOM C recognize option "password". If unset, "pass" is used
2277 (for backwards compatibility).
2279 Fixed a bug in Generic Frontend Server that could make it crash if a
2280 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2283 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2284 Must be issued before open, in order to be in effect.
2286 --- 2.0.9-6 2004/01/12 Debian/Windows
2288 Make the SRU server more picky WRT unknown params, etc.
2290 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2292 New YAZ client command, options, that sets Z39.50 options.
2294 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2295 options from a string of tokens (one token for each option bit).
2297 Update SRW diagnostic code messages.
2299 --- 2.0.9-5 2004/01/07 Debian/Windows
2301 Handle user defined stylesheet for SRW/SRU.
2303 --- 2.0.9-4 2004/01/06 Debian/Windows
2305 Fix bug in decoding of Content-Length.
2307 --- 2.0.9-3 2004/01/06 Debian/Windows
2309 Fix a bug with decoding of XML packed records.
2311 --- 2.0.9-2 2004/01/05 Debian only
2313 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2315 Fix bug in SRW/SRU diagnostics decoding.
2317 --- 2.0.9 2004/01/05
2319 Fixed bug in Generic Frontend Server which could drop records exceeding
2320 preferred message size. Reported and fixed by Irina Dijour.
2322 Fixed calculation of package size for structured records in Generic
2323 Frontend Server. Reported and fixed by Irina Dijour.
2325 Fixed namespace for SRW/SRU diagnostics.
2327 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2329 --- 2.0.8 2003/12/22
2331 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2332 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2335 CQL changes to reflect recent changes to the specification:
2336 * Documentation talks about context sets instead of index sets.
2337 * Documentation talks about indexes instead of qualifiers.
2338 * The CQL-to-PQF transformer's configuration file now uses
2339 "index.set.name = <attributes>" instead of the old form
2340 "qualifier.set.name = <attributes>". (Both forms are still
2341 understood but the latter is deprecated.)
2342 * CQL terms with no explicit index specified are now interpreted as
2343 cql.serverChoice instead of srw.serverChoice (which of course
2344 behaves exactly the same.)
2346 --- 2.0.7 2003/12/16
2348 MARC conversion can now generate ISO2709 output in another
2349 character set. yaz-marcdump uses this facility if you invoke it
2352 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2353 functions from there can be used from C++.
2355 --- 2.0.6 2003/12/04
2357 Frontend server now transfers memory from decoded packages to stream
2360 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2361 references to show up.
2363 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2364 the ZOOM Abstract API. The older names for the same options are still
2365 also supported for the benefit of old applications.
2367 ZOOM-C supports "implementationId" and "implementationVersion" options
2368 to go along with "implementationName". These allow the user code to
2369 specify identification strings to be sent to servers.
2370 Add OID for the new ExtLite attribute set.
2372 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2373 as requested/supplid by Ere Maijala <ere@atp.fi>
2375 For generic frontend server, reverse the order of
2376 "toolkit-supplied / application-supplied" strings sent as implementationId,
2377 Name and Version. Also, remove the spaces around the slash. This brings
2378 the GFS in line with the behaviour of ZOOM-C on the client side.
2380 Add function ZOOM_scanset_display_term.
2382 yaz-client shows scan displayTerm if present.
2384 Utility yaz-iconv is now installed by default along with the man page
2387 Extend configure check for OpenSSL to use pkg-config where available (such
2390 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2391 server to specify uid/gid/mask for socket using the format
2392 unix:[user=uid,][group=gid,][umask=mask,]file=path
2393 If file= is omitted the existing format is assumed, e.g.
2395 in which case the mask is 0666 (rw for everybody).
2397 Major restructure of YAZ source. All source in libyaz is in src directory.
2398 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2399 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2401 Added man page for utility yaz-marcdump (used to be called marcdump).
2402 yaz-marcdump is installed by 'make install'.
2404 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2405 of incoming package failed.
2407 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2409 Change prototype of odr_perror: add const to message string.
2411 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2413 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2414 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2415 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2416 DNS lookup. There should not be any compatibility problems with this
2417 assuming that blocking=1 or 0 is used.
2419 Fix bad reference in UNIX comstack in function cs_addrstr.
2421 Fix for compilation on AIX.
2423 The generic front-end server (server/seshigh.c) now supports returning
2424 Init diagnostics to the client in User-information-field, in
2425 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2428 --- 2.0.4 2003/09/04
2430 Allow any CQL relation (not just all,any,exact,scr).
2432 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2433 that features the same UI.
2435 Implemented command update0 in YAZ client which is equivalent to
2436 update but uses old of Ext Update ASN.1.
2438 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2439 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2440 Previously no OID was used for this info.
2442 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2443 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2444 returns 'malformed search term' otherwise.
2446 SortResponse member resultCount now set to NULL in sort handler of
2449 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2452 Add three new utility functions for translating OIDs between various
2453 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2454 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2455 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2456 char *oid_to_dotstring(const int *oid, char *oidbuf);
2457 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2459 Reverted modifications for ES Update definition for z_IU0Update
2460 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2461 is back to YAZ 2.0.2.
2463 String value attributes for CCL parser.
2465 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2466 which their FirstSearch server returns in Init responses, sometimes
2467 carrying useful diagnostic information when Init fails. This has the
2468 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2469 "z39.50/oclcui.asn", where its definition is somewhat different from
2470 what OCLC document on their web-site, as required to interoperate with
2473 Support for anonymous authentication in yaz-client. Use the command
2476 * Fix the OID of the Index Data-local "admin" Extended Service from
2477 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2478 the 1000, which indicates a locally-defined OID, was a mistake.
2480 --- 2.0.3 2003/06/20
2482 Fix CCL directive @case handling so that it affects string match for
2483 both CCL keywords and qualifiers.
2485 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2486 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2487 Decoder has been updated with ASN.1 changes as listed in
2488 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2489 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2490 z_IUUpdate, remains unchanged.
2492 ZOOM_record_get may now return a record in a specific character set.
2493 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2494 "from" is the character set of record as returned by target. "to" is
2495 the character set to be returned. If omitted, "to" is UTF-8.
2497 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2499 New ODR utility, odr_getelement, which returns name of element for
2500 which encoding/decoding failed.
2502 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2503 in cases where a required element was omitted.
2505 Bug fix: some MARC8 sequences were not converted.
2507 New ZOOM option "step" which specifies number of records to be
2508 retrieved in one chunk. Used in conjunction with "start" and "count".
2510 SRW support for yaz-client. Use scheme http: to use it, e.g.
2513 yaz-client no longer does (un)intelligent character set conversions
2514 by default. Can be enabled with charset and marc_charset commands.
2516 xmalloc trace fix for 64-bit systems such as DEC alpha.
2518 Solaris 2.6 compile fix.
2520 New function, cql_strerror() translates SRW error codes, as returned
2521 by cql_transform_error(), into human-readable English strings. Used
2522 in yaz-client diagnostics when appropriate.
2524 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2525 converts it into a type-1 query which is sent to the server. This
2526 makes CQL available for use with all Z-servers, as opposed to the tiny
2527 minority that can handle CQL queries themselves.
2529 --- 2.0.2 2003/04/28
2531 New Debian package layout similar to the Redhat Package layout.
2533 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2534 and search result respectively.
2536 --- 2.0.1 2003/04/25
2538 Redhat package is now several packages: libyaz (runtime libraries),
2539 libyaz-devel (development and documentation, and yaz (utility programs).
2540 Package spec file by Morten Bogeskov.
2542 New member 'schema' in struct bend_fetch_rr which the name of requested
2543 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2544 handler MAY set this to reflect the schema of the returned record.
2546 New member 'display_term' in struct scan_entry. GFS now sets member entries
2547 and allocates scan entries to be filled by user scan handler. In previous
2548 version, entries member was allocated by the scan handler. That still works,
2549 but the GFS will ignore member display_term - assuming it was NOT set by
2550 the handler. The fact that the GFS now allocates the entries both allows
2551 for new members and makes a scan handler easier to write.
2553 Fix CQL lex buffer overflow.
2555 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2556 SRU default recordPacking is string.
2558 SRU protocol support for frontend server.
2560 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2562 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2564 Added scan for the ZOOM shell (zoomsh).
2568 * String Identifers for Schemas (Amendment 5).
2569 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2570 Old definition for schema
2571 Odr_oid *schema; /* OPT */
2576 Z_InternationalString *uri;
2577 #define Z_Schema_oid 1
2578 #define Z_Schema_uri 2
2581 * resultCount parameter to Sort Response (Amendment 1).
2582 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2584 Support for SRW 1.0 over HTTP. This is an optional feature and
2585 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2588 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2589 on the same port. SRW SearchRetrieveRequests are mapped
2590 to bend_init,bend_search,bend_fetch,bend_close.
2592 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2594 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2595 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2597 ZOOM connections are SRW based if schem http is used for hostname
2598 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2599 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2601 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2602 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2603 distance=n, order=true/false, relation=le, prox unit=word. If
2604 n is omitted, distance 1 is used.
2606 Fixed problem with C compiler include path in wrong order.
2608 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2609 on Solaris. Patch from Ko van der Sloot.
2611 New MARC decode API. All new functions operate on a yaz_marc_t
2612 handle. The most important new functions are: yaz_marc_create,
2613 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2614 decode and destroy respectively. Decoder can produce formats
2615 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2616 include/yaz/marcdisp.h.
2618 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2619 to UTF-8, UCS-32, wchar_t or Latin-1.
2621 * Prototypes for yaz_iconv_-functions moved to separate header
2622 include/yaz/yaz-iconv.h.
2624 Make a few private functions 'static' in unix.c. This prevents
2625 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2627 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2628 are set when Init Response is received.
2630 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2631 but returns diagnostic set as well.
2633 New function yaz_strerror which is a portable wrapper for
2634 strerror/strerror_r/GetLastMessage.
2636 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2637 is returned for MARC. If type is "oai", then OAI MARC is returned.
2639 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2642 --- 1.9.2 2002/11/26
2644 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2646 Fix bad race conditions on SIGTERM and terminate gracefully in
2649 Move retrieval (data1) module to Zebra since nobody seems to be
2652 Add GRS-1 render for ZOOM using same format as yaz-client.
2654 --- 1.9.1 2002/10/05
2656 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2658 Fix broken ESpec handling in data1 module.
2660 SGML reader parses comments and makes them part of the data1 tree.
2662 Added several type casts so that YAZ compiles as C++ code.
2664 ZOOM didn't handle PDU encoding failures properly.
2666 Added more Bib-1 diagnostics (approved extensions).
2668 GNU configure: better check for iconv.
2670 More portable use of accept, getpeername. Check for socklen_t. Use
2671 int/size_t if socklen_t is not defined.
2675 PQF parser rejects bad queries - including those with extra
2676 characters in them. PQF parser used to silently ignore that.
2677 Cleaner API for PQF added, which allows you to get detailed
2678 error information for bad queries (see yaz/pquery.h).
2680 Fixed bug in ZOOM_record_get for type "database".
2682 Implemented mini iconv library supporting conversions between
2683 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2685 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2687 --- 1.8.9 2002/08/20
2689 Fixed ZOOM C record cache so that preferredRecordSyntax and
2690 elementSetName is used to check for already fetched records.
2692 --- 1.8.8 2002/08/02
2694 Added three members in bend_initrequest structure to facilitate
2695 character set negotiation.
2697 Fixed a bug in frontend server that could cause indefinite
2698 loops under rare conditions.
2700 Revised character set utilities (charneg.h) so that encoding
2701 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2703 For PQF, directive @term <type> sets term type for Scan/Search.
2704 Here <type> is general, string, numeric, null. The term type
2705 is inherited - just like @attr.
2707 New call odr_set_charset that sets character set conversion for
2708 international-strings on a ODR stream. Prototype is:
2709 int odr_set_charset(ODR o, const char *to, const char *from);
2710 The InternationalString is still represented as C string in YAZ
2711 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2712 won't). On the protocol level, you can use any encoding.
2714 Support for UNIX sockets in ZOOM.
2716 Solaris recv sometimes returns errno == ENOENT. It is treated as
2717 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2719 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2720 both client and server. Code by Morten Bogeskov.
2722 --- 1.8.7 2002/05/22
2724 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2725 that they can be used directly from Visual Basic. You must recompile
2726 your windows APP if you're using ZOOM.
2728 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2729 Commands "lang" and "charset" sets language and character set respectively.
2730 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2731 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2733 Attributes from multiple CCL fields may be OR'ed rather than merged
2734 using directive "@field or". Fields are still merged by default -
2735 equivalent to "@field merge".
2737 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2740 Fixed bug in zget for parameter ExtendedServicesResponse.
2744 --- 1.8.6 2002/03/25
2746 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2748 Client displays USR.1:SearchResult-1 (hits per term).
2750 Additional Search Info for search in Generic Frontend Server.
2752 Fixed CCL parsing of "field=s".
2754 WIN32 installer - using the excellent NSIS software from nullsoft.
2756 Fixed CCL parsing of "field = - <number>".
2758 Added function yaz_marc_decode that decodes MARC for line mode
2759 display or XML (similar to that used by JZKit).
2761 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2762 Z39.50. But ISO/ILL was, however.
2764 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2765 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2767 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2768 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2770 --- 1.8.5 2002/02/03
2772 New YAZ client features: Command completion and new commands:
2773 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2774 Code provided by Jacob Poulsen.
2776 New call oid_trav, that visits all registered OIDs via callback.
2778 Function ZOOM_record_get now returns const char pointer rather than
2779 void pointer. It saves a lot of type casts.
2781 For YAZ client, command "auth" now allows you to set authentication
2782 in IdPass style. It is enabled when three tokens are given - order
2783 is user, group and password.
2785 Fix memory leaks in MARC record handling for ZOOM.
2787 New option for YAZ client, -k <kilobytes> that sets
2788 maximum record size. Similar to -k option for generic frontend
2789 server and yaz-ztest.
2791 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2793 Prefix query parser reports "fail" when bad attribute set is given.
2795 Fix in MARC decoder. Proximity logging. Fix for attribute set
2796 in scan handler for server. Patches by Shigeru Ishida.
2798 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2801 Configure option --with-openssl=<dir> now works when a directory is
2802 specified. Patch provided by Morten Bogeskov.
2804 New option for YAZ client, -u <auth>, that sets authentication.
2806 ZOOM fix: error information was sometimes "missing", since error
2807 was cleared/reset too when it shouldn't.
2809 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2811 --- 1.8.4 2002/01/04
2813 Scan for ZOOM API. New object ZOOM_scanset. New functions
2814 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2815 ZOOM_scanset_destroy.
2817 New ZOOM function, ZOOM_connection_last_event, that returns type
2818 of last event (such as "receive data", "send data", "apdu received",
2821 New ZOOM option, schema, that specifies schema for retrieval.
2823 New CCL feature. Qualifiers can be aliases for one or more
2824 other qualifiers (if more than one is given, OR is used).
2826 ZOOM uses named result sets if target supports it.
2828 Two new YAZ client commands: . (dot, which sources a script of YAZ
2829 client commands), and ! (to execute shell command.). Implemented
2832 Working on Debian packages.
2834 --- 1.8.3 2001/11/19
2836 YAZ client enables named result sets only if target supports it.
2838 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2840 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2841 with key="host" to get same result.
2843 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2844 Function Z3950_resultset_record(s) returns references to records
2845 "owned" by resultset. To become owner use Z3950_record_clone.
2847 Function z_ext_record handles Extended Services. Thanks to
2850 --- 1.8.2 2001/11/12
2852 CCL Parser fix: ignore token comma when dealing with and-lists.
2854 Documentation updates for COMSTACK.
2856 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2857 Changed prototype Z3950_records. For some functions, int parameters
2858 were changed to size_t.
2860 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2863 New MARC decode/display function, marc_display_exl, which properly rejects
2864 non-ISO2709 records. YAZ client uses it.
2866 --- 1.8.1 2001/10/29
2868 Fix bug: local attribute set wasn't set correctly in PQF strings.
2872 * Old Z39.50 codecs no longer supported.
2874 Added ZOOM C binding. See http://zoom.z3950.org/
2876 Renamed states for COMSTACKs to avoid confusion with events.
2878 Implemented cs_look and proper cs_rcvconnect.
2880 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2882 Configure detects POSIX threads on OpenBSD.
2884 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2885 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2887 When error is returned from present handler, non-surrogate diagnostic
2888 is returned in present response (and fetch handler is no longer called).
2890 * Minor adjustments to pquery parser (PQF). Token characters may be
2891 escaped by using backslash (C-style).
2893 PQF parser allows string attribute values to be specified. For @attr,
2894 non-numeric characters after the equal-sign are treated as strings
2895 (e.g. @attr 9=title).
2897 CCL trunction character may be defined (@truncation in file)
2899 * function zget_ExtendedServicesRequest sets waitAction to
2900 waitIfPossible (was wait).
2902 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2905 CCL operator names may be set in field definition files (CCL_bibset).
2906 See ccl/bib1 for an example.
2908 Fixes in ASN.1 compiler for C++ compatibility.
2910 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2911 and "op_or" to avoid conflict with C++.
2913 Fixed problem with GNU readline detection on Redhat 7.0.
2915 Added step-size for Scan backend handler.
2917 Fixed bug that made the frontend server crash when no attribute
2918 set was specified for scan.
2920 Front-end server automatically switches to original working directory
2921 when installed as an NT service. Previously -w had to be specified to
2924 Added extended attributes for retrieval module (data1), so that data1
2925 records carry d1_readXML/SGML attributes. d1_read also supports
2926 null-data rules ( <tag/>)
2928 On UNIX when POSIX threads are available, a separate library libyazthread
2929 is created. Programmers should link with that library and the yaz library
2930 when using threads. The reason for the split was that some applications
2931 on Linux, such as Apache, doesn't work well when using shared objects that
2934 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2935 (or any frontend server) in SSL mode by specifying ssl: followed by
2936 address. Only tested on UNIX.
2938 Added feature for CCL module. Virtual structure s=al or s=ol generates
2939 and-list and or-list respectively instead of phrase search.
2943 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2944 log_mask_str. This was done to avoid name conflicts with other libraries
2945 (such as other PHP extensions).
2947 Added raw OID member for preferred record syntax (request_format_raw)
2948 and returned record syntax (output_format_raw) for backend fetch method.
2950 Config file yaz-config now accepts options so that it returns specific
2951 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2953 Shared library support for UNIX using GNU libtool.
2955 * Modified backend interface. Request/Response struct's replaced by
2956 one read/write C struct. For example bend_fetchrequest and
2957 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2958 Every handler - even search has to be registered in bend_init
2959 handler. This means that the YAZ library no longer refers to
2960 external functions and it makes it possible to make the whole
2961 thing a single DLL/SO.
2963 Added Segment handler for backend server.
2965 Added Zmbol/Zebra administrative functions to YAZ client.
2967 Threaded frontend server on UNIX (when POSIX Threads are available).
2968 Starting the server with option -T enables multi-threading.
2972 Added configure option --enable-comp/disable-comp to control use
2973 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2974 located in sub directory asn.
2976 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2977 in ${exec_prefix}/bin along with the other programs yaz-client and
2980 GNU automake used to maintain makefiles.
2982 Added several OID's.
2984 Changed retrieval module so that we can load records with no abstract
2985 syntax defined. Tagpaths in these records are fully composed of string
2988 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2992 On UNIX, the generated makefile now supports a proper 'make install'.
2993 The prefix can be set via GNU configure to set the install location
2994 (default is /usr/local).
2996 * YAZ programs client and ztest were renamed to yaz-client and
2997 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2998 locations, such as /usr/bin,/usr/local/bin,etc.
3000 * YAZ Header files were moved from include to include/yaz. YAZ Header
3001 files are referred to as include <yaz/log.h> rather than <log.h>.
3002 The YAZ include path (-I ..) is therefore the same as before. Programmers
3003 should update their #include statements or use -Ipath/include/yaz
3004 instead. The main motivation for doing this change is that YAZ header files
3005 can be installed in "standard" locations /usr/include,/usr/local/include
3006 without introducing conflicts, since ALL YAZ header files are stored
3007 in subdirectory yaz (under /usr/include for example).
3009 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3010 rather than project/workspace files. We switched because project files
3011 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3014 Changed name of logging function, logf, to yaz_log, to prevent name
3015 clash with some math-log functions. The YAZ header log.h defines logf
3016 to yaz_log (#define) so there should be no incompatibilities by this
3019 Added bend_start/bend_stop handlers for server. These handler are
3020 called on start/stop of server. For windows they are called whenever
3021 a service is started/stopped.
3023 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3024 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3025 in util/yc.tcl. The auto-generated C code structures are, in a few
3026 cases, incompatible with the old decoders. There are differences in the
3027 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3028 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3029 The preprocessor variable ASN_COMPILED is defined when the compiled
3030 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3031 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3032 wish to use the old encoders/decoders you can specify --disable-yc
3035 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3036 version so that it supports both new - and old version of DB Update
3038 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3039 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3040 change. The name parameter can be set to 0 in which no name is specified
3041 for the construction. The macros odr_implicit and odr_explicit sets name
3042 parameter to zero for the construction involved. New macros
3043 odr_implicit_tag and odr_explicit_tag are similar to the others,
3044 except that a name parameter is added. For programmers' that don't use
3045 ODR they probably only need to change the call to z_APDU and z_External.
3047 Added access control facility by interfacing the TCP wrapper library.
3048 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3049 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3050 name of the daemon and enables the access control as specified in
3051 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3053 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3054 den Dool <H.M.vdnDool@kub.nl>.
3056 Added reference ID parameter to most functions in server API - refer
3057 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3059 Changed name of ccl library to libccl.a (was ccl.a).
3061 Fixed bug in decoder for Explain (Category TargetInfo).
3063 Added support for GNU readline in client. Thanks to Jacob Poulsen
3064 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3066 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3067 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3068 IMPLEMENTATION! This change was made to the development version before
3069 the ZIG decided to retract the amendment. If any users MUST be
3070 compatible with the original Update definition, PLEASE CONTACT US, and
3071 we will include a separate definition corresponding to the old Update
3072 ES. Note that because of the change to the ASN.1 of the
3073 TaskPackageRecordStructure we cannot define a single structure that
3074 will support both versions.
3076 * Added const modifier to buffer parameter for some ODR/BER encoding
3077 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3078 completeWAIS, odr_dumpBER.
3080 Fixed bug in client.c which caused a crash when a scanResponse didn't
3081 contain positionOfTerm.
3083 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3084 * will cause an error in a client if a non-YAZ target sends both a
3085 * list of Scan entries and non-surrogate diagnostics.
3087 Retrieval module enhancements. Tag sets may be typed in the reference
3088 to it. From the .abs-file the "tagset" directive takes a third optional
3089 integer type for the tag set referenced. From a .tag-file the "include"
3090 directive takes a third optional type as well. The old "type" directive
3091 in the tag set itself is still recognized but acts as the default type
3094 Backend interface change. Individual Scan terms returned from bend_scan
3095 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3096 in include/backend.h.
3098 Retrieval module enhancements. Multiple tag sets and attribute sets may
3099 be specified in abstract syntax specs. Revised the error/warning for
3100 logging messages reported by the retrieval module when reading the
3103 Object Identifier system (oid_..) changed. The API is backwards
3104 compatible but the oid-routines now allocates new OID's when needed.
3105 Raw OID's may be specified in oid_getvalbyname.
3107 YAZ now uses GNU configure to generate Makefile(s).
3109 * Minor changes in some of the member names of DeleteResultSetRequest and
3110 DeleteResultSetResponse. See include/proto.h.
3112 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3113 and added member 'languages' in TargetInfo (which was missing).
3115 Changed the way attribute sets are handled in the retrieval
3116 module. These are now cached, just like the abstract syntaxes
3119 Changed YAZ so that it links with compiled ASN.1.
3121 Added Explain-schema definitions and mapping routines. The following
3122 Explain categories have been implemented: AttributeDetails,
3123 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3125 Fixed minor bug in Windows version of Server Library.
3127 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3129 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3131 Added EXTERNAL: UNIverse Resource Report (non-standard).
3133 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3134 ENUMERATED and SET OF.
3136 * Added 'const' to some of the char pointer arguments for the
3137 functions, data1_read_node, data1_getelementbytagname,
3138 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3141 Fixed bug in data1_insert_taggeddata - the last_child member of
3142 parent wasn't initialised.
3144 * Changed data1_read_record and data1_read_node so that the supplied
3145 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3146 doesn't refer to any parts of the "SGML"-buffer.
3148 Fixed bug in server library (Windows version of statserv_remove).
3150 * Changed code so that it compiles as C++. The type definition
3151 of Odr_fun which is a member of Odr_arm was changed. The result is,
3152 that an explicit typecast is needed for the fun pointer when
3153 using Odr_arm - as in:
3154 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3156 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3158 Implemented the new structured date and time definition as approved
3159 by the ZIG. Added schemaId element to the specificTag in Espec-1
3160 (also approved at the last ZIG). Thanks to RVDM.
3162 Added some Object identifiers (RVDM).
3164 Changed the Update Extended Service (RVDM).
3166 Added command "refid" to client which specifies referenceId for
3167 the following requests.
3169 Implemented extended service handling for server. See ztest.c
3170 for an example as well as backend.h. New handlers are registerd
3171 in the Init handler.
3173 * Changed interface for sort in server.
3175 Added new members to statserv_options_block. It allows a server
3176 to read options from another source than just the command line. Thanks
3177 to Charles Woodfield.
3179 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3180 renamed to zboolean. Some C++ compilers complained about the name.
3182 Minor changes to gils.abs. Added index 's' (sort) on title
3183 and date/time-last-modified.
3185 --- 1.4pl2 1998/1/30
3187 Fixed bug in server library regarding inetd mode (-i). This bug
3188 was introduced by release 1.4.
3190 --- 1.4pl1 1998/1/29
3192 Added sort facility in client and backend server interface.
3194 Fixed problem with dependencies in Makefile(s).
3196 Fixed bugs for encoders/decoders of extended services and
3199 Implemented sub-tree feature for schemas. Sub-trees are
3200 referenced in *.abs-files. See explain.abs for an example
3201 of the use of this feature.
3203 Modified bib1.att; local attributes for ANY didn't include
3204 ANY itself (only affects use of the retrieval module).
3206 Fixed bug in plain SGML reader in function data1_read_node:
3207 tags with prefix "var" was incorrectly interpreted as variants.
3209 Added feature "sub-schemas" to enable references to - and definitions
3210 of - group of elements.
3212 * Removed member parent from type data1_element (in data1.h).
3214 Implemented function odr_nullval() that returns the value of
3217 * Removed member num_children from data1_node (in data1.h).
3219 Made NT service interface part of the server library. The
3220 function statserv_main uses the NT service when required and
3221 calls the statserv_start / statserv_close routines.
3223 Routine zget_SearchRequest and zget_PresentRequest fills
3224 resultSetName/Id member with "default" instead of "Default".
3226 Fixed memory leak in server. Request queue member wasn't freed.
3228 Fixed nmem_exit so that memory is freed.
3232 Revised the CCL parser utility to be thread safe.
3234 Added function, oid_ent_to_oid, to replace the function
3235 oid_getoidbyent, which is not thread safe.
3237 * Added nmem_init and nmem_exit to initialize and release
3238 NMEM resources. Function nmem_init should be called once in the
3239 initial thread before NMEM/ODR is used. statserv.c and client.c
3240 have been changed accordingly. The change was necessary to make
3241 NMEM thread safe. The NMEM memory pool is shared amongst threads
3242 in a process. Unix-based applications will still work fine without
3245 Added NT Services interface for the the Z39.50 (statserv) Server.
3246 Refer to the ztest.c source on the usage.
3248 Windows 95/NT port using MSVC5.0. Project files are included in the
3251 * Defined new 'global' handle for the retrieval (data1) system. The
3252 new handled, data1_handle, describes the state of the data1 system.
3253 This handle is passed as first argument to virtually all
3254 data1 related routines. The functions data1_create and data1_destroy
3255 creates and destroys a data1 handle respectively.
3257 Added ODR encode stream member to all backend request structures
3258 init, search, scan etc. This stream should be used to allocate all
3259 memory used for the response when thread safe operation is needed.
3261 Changed the comstack utility, cs_addstr, to be thread safe. The
3262 returned hostname string returned by the function is now part the
3265 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3266 function. The cs_straddr takes a COMSTACK handle as argument, so this
3267 function must be used after cs_create and before bind/connect.
3268 This function is thread safe.
3270 Moved test server to 'ztest' directory - generic server code still
3271 in 'server' directory.
3273 Made prefix query (pquery.c) utility thread safe.
3275 Added new function modifier YAZ_EXPORT to 'export' public DLL
3276 functions when using windows (see include/yconfig.h).
3278 Added definitions to the OID database (util/oid.c) (RVDM).
3280 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3282 Added call to ccl_rpn_delete in client program.
3284 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3285 release of RPN structure.
3287 Added support for C++, headers uses extern "C" for public definitions.
3288 With input from RVDM.
3290 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3291 Thanks to Ronald van der Meer (RVDM).
3293 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3295 Added support for private extensions to the OID database
3296 (oid_setprivateoids()). Thanks to RVDM.
3298 Added optional, physical ANY (key replication)
3300 Fixed null-reference problem in GRS-1 output filter.
3302 Proximity operator added to Prefix Query Format (PQF).
3304 In test client command "base" accepts multiple databases.
3306 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3310 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3312 Smallish bug-fixes in the new encoders/decoders (explain).
3314 Bug fixed in DeleteRequest.
3316 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3318 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3320 Added SOIF syntax (using private OID for now) to retrieval module and client.
3322 Added Update extended service.
3324 Added SearchResult-1 additional info structure.
3326 Added optional CCL (ISO8777) interpreter as separate module. Available
3329 --- 1.2 1996/6/10 (1st anniversary release)
3331 Added Summary record syntax. Lightly tested.
3333 Added OPAC record syntax. Untested.
3335 Added ResourceReport service encoders/decoders. Untested.
3337 Fixed bug in z_Unit - wrong tagging on unitSystem.
3339 Fixed bug in the DiagRecs decoder.
3341 Added options for max PDU size and session timeout to frontend-server.
3343 Added documentation of query-language parsers and other supporting utilities.
3345 [frontend-server] Added Attribute set to the bend_scanrequest API.
3347 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3348 surrogate diagnostics were generated.
3350 [retrieval] Allow multiple local values for attribute.
3352 [retrieval] Allow multiple attributes per element in .abs files. index type.
3354 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3356 --- 1.1pl2 1996/4/10
3358 Minor changes, mostly specific to Zebra's requirements (retrieval)
3362 Repaired bug in frontend server when running multiple listening
3363 endpoints in dynamic mode.
3365 z_External() now won't break if a known, ASN.1 value comes encapsulated
3366 in an octet-string. The value will pass through unmodified in an Odr_oct.
3368 Added a bit of code to the demo client to decode & display
3369 ASN.1-structured records represented in the octet-aligned branch of
3370 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3372 Added z_ext_getentbyref() to the ASN module. Doc updated.
3374 * Completed the SCAN definition in the ASN module. This may break SCAN
3375 code based on older YAZ-versions at compile-time. The fix is easy -
3378 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3379 under the SCAN definition. Remember to initialize this, server-people.
3381 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3382 that this does not extend to ODR and ASN.
3384 Comstack allows insertion of established socket (primarily for
3385 inetd-operation of servers). Doc updated.
3387 Front-end server can now start from the inetd in TCP mode. Doc
3390 --- 1.0pl4 1996/1/24
3394 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3395 the rank and record number.
3397 Adjustments to the frontend server.
3399 Fixed diagnostic BER dumper. It ignored the file argument.
3403 Various changes to retrieval module.
3405 Changed the union discriminators of the protocol files from enums to
3406 ints paired with #defines.
3408 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3411 *Changed operator in the RPN structure to 'roperator', again to avoid a
3414 Fixed problems in Explain decoders/encoders.
3416 --- 1.0pl2 1995/12/6
3418 Memory bug in log module fixed.
3420 --- 1.0pl1 1995/12/5
3422 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3424 Bug in Explain DatabaseInfo module fixed.
3426 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3430 The shift to v1.0 signals that we now consider the *core* functionality
3431 of YAZ reasonably stable (the core being more or less equivalent to
3432 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3433 tested (Explain not at all - though that will happen soonish).
3435 Minor changes to code to support Windows port.
3437 Various minor changes after we're getting to use GRS-1 & co. more.
3439 Added Espec-1 format.
3441 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3442 of the protocol and it cannot be selected when encoding (maps into 'string'
3443 when decoding). Needed to talk to some servers.
3445 Demo client can request simple element set names.
3447 Added Diagnostic Format encoders/decoders.
3449 Added simple Close handling to frontend server (no hooks for resource
3450 reporting yet), and demonstration client.
3452 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3454 --- 1.0b3 1995/08/24
3456 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3457 handled incorrectly when records were requested in the searchResponse. This
3458 will only affect you if you use the frontend-server.
3460 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3461 Test-client will ask for and print GRS1. Ztest will return dummy records
3464 Added Explain encoders/decoders to the service-level API. Untested.
3466 Added Extended Services: Item Order encoders and decoders to the Service-
3467 level API. Untested. We could use a recent copy of the pertinent bits
3468 of the ILL protocol to add those bits.
3470 Added diagnostic format 1 encoders/decoders to the service-level API.
3473 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3474 odr_cons.c, which causes a more correct output.
3476 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3477 was always set to 0 when no records were requested in the searchRequest.
3479 * Added better external-handling. This shouldn't harm old code that
3480 *encodes* externals. It can break code that looks for a
3481 'single-ASN1-type' representation, since those types that are known
3482 are now decoded immediately. Look at the SUTRS sample code in
3483 seshigh.c and client.c. Documentation updated.
3485 Handling of structured records in bend_fetchresponse. Length -1 marks
3486 structured record, type is deduced from format field.
3488 --- 1.0b2 1995/06/27
3489 Fairly quick maintenance release to add SUTRS support.
3491 Fixed handling of SUTRS records in the demonstration client.
3493 * Added format field to the bend_fetchrequest and bend_fetchresponce
3494 structures of the backend API (frontend server). When the record is
3495 returned, the value of the format field is mapped to an OID. The
3496 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3497 of the record. The special value VAL_NONE in the bend_request means
3498 that no specific format was requested by the client. Documentation
3499 updated accordingly. Test server (ztest) will return a fixed dummy
3500 SUTRS record if your client requests SUTRS.
3502 Documentation updated accordingly.
3504 You can now set external libraries and RANLIB support in the top-level
3508 First public release.
