3 For MARC XML parsing, allow record without leader. A fake/default leader
4 is inserted and a warning is tagged with the record.
6 ICU: fix leak in in icu_iter_get_org_info.
10 ICU: fix bug in icu_iter_get_org_info (un-init variable).
14 Implement z_HTTP_header_remove.
18 ICU: Disallow 0 ptrs for some ICU string utilities.
20 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
21 returns original tokens (before normalization).
23 CCL: avoid z39.58/regex truncation when not needed. Apply only the
24 conversion of those masks, when absolutely necessary.
26 CCL: configurable masking character - @mask. Default masking character
29 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
30 full response anyway, so a Transfer-Encoding header will obstruct the
35 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
36 picking a socket. Problem is that some systems has IPV6 support, but
37 we can't create sockets for them, so we pick AF_UNSPEC first.
39 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
40 use content_len to determine resulting Content-Length in HTTP response
41 and NOT Content-Length supplied in headers by user.
43 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
44 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
46 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
49 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
50 with big endian and unsigned char (by default).
54 Fix yaz-client connect (crash in 4.2.55).
58 Fix proxy/host problem for ZOOM that could occur if unix sockets
61 New Debian package libyaz4-dbg.
63 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
64 differently in tcpip_close.
68 Windows installer of YAZ includes YAZ4J as a component.
70 CQL: allow "extra terms" again, by default. Thus, the CQL parser
71 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
72 and earlier. CQL parser may operate in strict mode where queries
73 not conforming to the standard BNF are rejected (syntax error).
74 Whether the CQL parser operates in strict mode is controlled with
75 cql_parser_strict . Strict mode enabled with option -S for utilities
76 cql2pqf and cql2xcql .
78 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
82 New charset, MARC-8c, which is like MARC-8 but allows control characters
83 0x01 through 0x1F, except ESC to be passed through verbatim.
85 Fix a problem with duplicate sub field character in MARC output. Problem
86 happened only when output was MARC-8 encoded.
90 yaz-ztest: Use hash for fake hit count. Before, random number was used.
91 This is problematic for unit tests using yaz-ztest. This patch also makes
92 a hash for CQL queries. For RPN, any term with a leading digit will be
93 treated as pseudu hit count (to force any particular hit count by a client).
95 yaz-ztest: return unique MARC dummy records. Beyond record offset
96 24, the author surname is patched with offset to make all records
99 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
100 on system wide default (/proc/sys/net/ipv6/bindv6only).
101 @4 binds to IPV4 only. @6 binds to IPV6 only.
103 Update CQL API documentation a bit
105 CQL: don't accept extra terms for queries. Makes the CQL parser
106 stricly conformant to the standard.
108 --- 4.2.51 2013/02/12
110 GFS: scan handler gets extra_args from request and may return extra
111 response data . That's for SRU only.
113 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
115 --- 4.2.50 2013/01/30
117 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
119 OPACXML: sync spelling of availabilityDate in XML to that of Schema
120 opaxxml.xsd. The schema had the correct spelling of this member always.
121 The ASN.1 was mis-spelled and still is (API change) - we are
122 not changing this. However, the OPAC to XML conversion had yet
125 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
128 New function, z_ext_record_oid_nmem, which is similar to
129 z_ext_record_oid but takes NMEM rather than ODR
131 --- 4.2.49 2013/01/18
133 ICU: New conversion element 'join' which joins tokens into one
134 with a custom character given by rule attribute.
136 --- 4.2.48 2013/01/10
138 New GFS search member: present_number. This is a hint to the
139 search handler how many records are going to be fetched immediately
140 following search. There's no guarantee that it's going to be the case,
141 since it depends on hit count (for Z39.50 piggyback) and whether errors
144 Make a few functions static (private). The functions getbyte_stream,
145 ungetbyte_stream and yaz_gets are now private. They were never declared
148 yaz-marcdump: exit(5) for serious decoding errors
150 ISO2709 decoding: be more picky WRT header
152 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
153 was only used as to indicate that next-result-set-position should be
155 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
156 Based on patch from Ashley Sanders.
158 Make some functions static/private in PQF parsing. Those functions were
159 never declared in a public header and so should not be in use by
160 applications based on YAZ.
162 --- 4.2.47 2012/11/23
164 ZOOM: special options to control APDU logging.
165 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
166 logging of APDUs until "saveAPDU" option is set again. If logging is
167 already enabled the effect is that current APDU buffer is cleared.
168 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
169 logging (default behavior on new connection).
170 The APDUs sent/received can be obtained by using
171 Using ZOOM_connection_option_get(c, "APDU") or
172 ZOOM_connection_option_getl(c, "APDU", &l).
174 GFS: relay implementation_version from backend
175 From 3.0.40 and later, implementation_version from backend was
176 not used in init response at all.
178 --- 4.2.46 2012/11/15
180 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
181 mode at all. Probably never did.
183 Make a new version of ztest.pem that, at least, is not expired.
185 --- 4.2.45 2012/11/13
187 Fix description of CCL directive 'case'.
189 More tight checking of form arguments (yaz_uri_to_array). Makes
190 YAZ better at rejecting big and/or bad POSTs.
192 SRU decoding does not report more than up to 10 invalid arguments.
194 rpn2cql: less quotes in generated terms. Semantics unchanged, but
195 it's prettier this way.
197 --- 4.2.44 2012/10/25
199 New utility yaz_decode_init_diag. Defined in proto.h.
201 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
202 given for unix local socket.
203 The COMSTACK string for doing so is:
206 unix:/myfile:tcp:localhost:9999/mybase
207 unix:/myfile:localhost:9999/mybase
208 unix:/myfile:http://fakehost/mybase
210 debian: Use dpkg-buildflags in build process.
212 --- 4.2.43 2012/10/19
214 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
215 global's SRU service uses a recordPosition scheme starting from zero.
216 First record's position should be one
217 according to the standard.
219 --- 4.2.42 2012/10/18
221 Allow more namespaces for SRU. This is to allow, for example, an
222 incorrect namespace returned from server
223 http://services.igi-global.com/sru .
225 Minor fixes for compilation on Windows.
227 --- 4.2.41 2012/10/11
229 daemon: log total number of bad signals from child on stop so that it
230 is more easy to spot problems with child worker processes.
232 retrieval: empty backend name attribute omits element set
233 from being used in retrieval.
235 --- 4.2.40 2012/10/04
237 Implement Solr sort strategy "solr", similar to sru11 sorting.
238 This will implement the correct parameters on Solr requst to do
241 --- 4.2.39 2012/09/28
243 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
246 MARC: Extra/missing indicator handled for MARCXML.
247 The indicator length is given in header and is the same for the
248 whole record. If attributes ind1, ind2 are missing, then content
249 character defaults to blank. Extra indicator attributes (beyond)
250 indicator length are treated as an error.
252 Reformat: delete trailing whitespace
254 --- 4.2.38 2012/09/17
256 MARC: fix non-ASCII characters for leader. This is to ensure we can
257 generate XML in UTF-8.
259 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
260 in one node with structure word.
262 --- 4.2.37 2012/09/04
264 yaz-json-parse: JSON output may be pretty printed by using option
267 Increase default value of max message for Z39.50 Init for GFS, ZOOM
268 and yaz-client. Old value was 1 MB. New value is 64 MB.
270 --- 4.2.36 2012/08/22
272 yaz-client: don't display bogus records from SRU servers. Some SRU servers
273 return more records than given by *maximumRecords*. Skipping those in
276 record_render: simplify buffer return handling and fix at least one bad
277 memory reference, that broke the test_embed_record sometimes.
279 Allow http://user:pass@host notation for yaz_url_exec.
281 zoomsh: allow shell command to be executed. Via the system(3) call.
283 yaz_poll: Allow num_fds == 0
285 yaz-client: fix bad encoding of "itemorder item". The itemorder
286 item <no> - command forgot to use length of encoded Item Request
287 package. Error present since YAZ 3.
289 yaz-ztest: fix bad usage of session handle. Bug was introduced when
290 result sets were saved (271a9c83).
292 SRU recordPacking: guess record packing in response rather than looking
293 at the recordPacking element which, OF COURSE, changed semantics in SRU
296 Decode SRU 2.0 responses. The official namespace for responses, according
297 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
298 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
299 nature.com's server, however, usee namespace
300 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
301 we are now using a glob-expr to match up the namespace. ZOOM C and
302 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
303 I can not find a single real example showing the "real" namespace in
304 the documentation from OASIS. The namespace for requests is different
305 from responses, but this is not added to YAZ yet, when we don't encode
308 --- 4.2.35 2012/06/26
310 zoom/record_render: add support for Base64 decoding fo MARC records
311 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
312 which will decode base64 + ISO2709 marc-8 encoded material from text node
315 --- 4.2.34 2012/06/07
317 Add missing definitions ZOOM_resultset_get_facet_field_by_index
318 and ZOOM_resultset_facets_names.
320 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
323 Change APDU dump printing to avoid long leading blanks. For levels 16
324 or larger the level is shown and the indentation is truncated but
325 recursed with modula 8. This makes it still reasonable easy to read
326 - even for nested BER dumps.
328 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
329 return 0 (incomplete package) in case where the BER package was
330 considered too nested (return value of -2).
332 dumpber: lines of level 15 are not indented further. Two spaces per
333 indentation; indentation 15 or more is indented to a fixed indentation
334 and augmented with a level=<no> indication.
336 zoomsh: increase max size of command+args
338 GFS: No limit in RPN buf size in CQL to RPN conversion.
340 --- 4.2.33 2012/05/09
342 New function for daemon utility, yaz_daemon_stop .
344 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
346 --- 4.2.32 2012/04/25
348 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
349 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
351 --- 4.2.31 2012/04/23
353 YAZ daemon utility relays SIGUSR1 to child process.
355 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
356 would result in en empty database list - which in turn would result in
357 encoding failure for search.
359 Fix reading beyond string in yaz_sort_spec.
361 --- 4.2.30 2012/04/11
363 Add two new SRU diagnostics:
364 236: Access to specified database denied
365 1015: Init/AC: Maximum number of simultaneous sessions for Userid
367 Document the very useful ZOOM-C option "apdulog".
369 CQL to RPN: term may be passed through verbatim. This is enabled with
370 truncation.cql . The assumption being that the term is already CQL.
372 --- 4.2.29 2012/03/20
374 record_conv: leader spec may be given for marc element.
375 The leader spec is given as attribute leaderspec for element marc.
376 For example to convert a MARC21 record from MARC-8 to UTF-8:
377 <marc inputformat="marc" outputformat="marc"
378 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
380 record_conv: allow user-XSLT params. For example:
381 <xslt stylesheet="MARC21slim2DC.xsl">
382 <param name="myparameter" value="myvalue"/>
383 <param name="otherparameter" value="othervalue"/>
386 record_conv: fix error handling for missing marc charsets.
388 CQL: fix extra terms in wrong order.
390 --- 4.2.28 2012/03/06
392 record_conv: modify new API for conversion types. The conversion types
393 may be passed in new functions yaz_record_conv_configure_t and
394 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
396 Avoid mixed statement/variable declare; fixes compilation with Visual
399 --- 4.2.27 2012/02/28
401 Add non-standard SRU diagnostic: 235: "Database does not exist".
402 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
403 Update SRU to Bib-1 diagnostic maps accordingly.
405 CCL: add two new diagnostics for unsupported masking. The new
406 diagnostics are: "Embedded truncation not supported" and
407 "Single charcacter mask not supported".
409 --- 4.2.26 2012/02/23
411 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
413 --- 4.2.25 2012/01/11
415 Build YAZ for Ubuntu Oneiric.
417 CCL: allow parantheses for proximity operands. For example CCL query
418 (a) % (b) is now allowed.
420 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
421 marked dead, rather then being destroyed. If not, the session memory is
422 being free'd before the search/scan handler is finished. Also destroy
423 'request' memory in request_release rather than in various places,
424 which resulted in leaks from time to time.
426 --- 4.2.24 2011/12/21
428 cql_sortby_to_sortkeys: honor sort prefix.
430 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
431 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
432 The rpn2cql family of functions now always returns quoted CQL terms.
434 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
436 --- 4.2.23 2011/12/15
438 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
439 sequence is treated as one. For example, &&a=b&&&c& is identical to
442 --- 4.2.22 2011/12/05
444 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
445 APDUs for a connection to a WRBUF.
447 --- 4.2.21 2011/11/23
449 Fix cql_sortby_to_sortkeys. Completely broken before.
451 Make CCL's @truncation work again.
453 --- 4.2.20 2011/11/09
455 New ZOOM connection setting: tproxy. It's like proxy, but does not
456 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
457 to set resolved address + port for a connection outside ZOOM itself.
459 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
461 --- 4.2.19 2011/11/07
463 Fix uninitialized variable in Solr spell support (could cause SEGV
464 for SRU response decoding).
466 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
467 back-end's addinfo through into the ZOOM response addinfo.
469 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
470 they are separated by a colon and a space rather than simply
473 --- 4.2.18 2011/10/28
475 Add support for Solr spell-checking/suggestions through ZOOM.
476 If a Solr target has been configured correctly for spelling-checking
477 and suggestions, these will now be returned on the ResultSet option
478 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
480 --- 4.2.17 2011/09/28
482 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
483 with a flag whether to substitute escape sequences or not.
485 --- 4.2.16 2011/09/22
487 Fix nmem_strsplit_escape to substitute escape char properly.
489 New option for zoomsh -e , which makes it abort on first error and
490 return process exit code to indicate success/failure.
492 YAZ options utility supports special option -- which makes all it treat
493 all following arguments as non-options.
495 --- 4.2.15 2011/09/16
497 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
498 searched if absolute filename is given.
500 Fix conv_xslt() error-reporting when stylesheet is not found.
501 (The value of fullpath is meaningless in this situation.)
503 --- 4.2.14 2011/09/07
505 Fix problem in CQL sort node creation: un-initialized memory.
507 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
508 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
509 CQL sortby depending on whether Type-1 or CQL is actually sent to the
512 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
513 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
515 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
516 will make it possible to use both single-character mask (#) and wildcard (?)
517 in CCL . Throw diagnostic for left truncation because that is not supported
520 --- 4.2.13 2011/09/01
522 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
523 cases using escapes (\-sequences) and masking.
525 PQF parse fix: A trailing backslash followed by end-of-string (\0)
526 would result in a read one byte beyond string.
528 rpn2ccl may use Z39.50 masking for terms (t=z).
530 ICU check fix. Don't include library -lCrun on Solaris, unless present.
532 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
533 not --cppflags (which seeems like an error in icu-config).
535 --- 4.2.12 2011/08/27 RPM package only
537 cql2ccl: fix conversion of terms: operator characters were not
540 --- 4.2.11 2011/08/25 RPM package only
542 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
543 CCL parser will map both # and ? to their regular expression
544 quivalents (. and .*).
546 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
547 of reserved CQL characters.
549 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
550 is, so that they are passed through.
552 --- 4.2.10 2011/08/24
554 ZOOM SRU mode: more aggressive re-connect.
556 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
557 made available as a utility function, declared in <yaz/logrpn.h>
559 rpn2cql_structure() supports proximity nodes (except that the Type-1
560 proximity node's "exclusion" binary is ignored, as there is no way to
561 express that in CQL). Fixes bug #4564.
565 Fix SEGV that could occur if set command of zoomsh was given without
566 value (2nd argument).
568 Fix SEGV that could occur if unsupported transport was given for
569 COMSTACK - say https (when SSL was unavailable).
571 Build yaz-url on Windows too.
575 New utility to get web content. Header is url.h. A command line tool
576 yaz-url is part of the distribution and packages.
578 Fixes for SSL COMSTACK (when gnutls is in use).
580 New functions yaz_base64{encode,decode}. Header is base64.h.
584 ZOOM C includes HTTP response buffer as additional info if it fails
585 to decode the SRU response.
587 Make wrbuf_json_puts available.
591 zoom: throw diagnostic for invalid value for option "sru". Before a
592 bad SRU request was sent.
594 Adding new utility wrbuf_vp_puts.
596 Add cclxmlconfig.obj to win/makefile. It was missing completely.
600 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
601 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
602 redirect was used at the same time.
604 MARC line mode decoding: be less picky about length given - first
605 5 digits of header that is.
607 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
609 Changes to decoding of SRU records: a record with recordPacking=xml is
610 modified with a new root element <yaz_record> if the recordData contains
611 multiple children elements. This is to make the record XML parseable
614 RPN to Solr conversion: encode special characters.
616 Generic Frontend Server: fix uinitialized member, stepSize.
620 Fix a bug in SRU decoding of records.. The database records stored
621 had un-initialized memory, but it would only be seen with yaz_record_render
622 and type_spec="ext" .
624 Fix a bug in ccl_qual_dup introduced in 4.2.3.
628 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
632 Add new utilities to convert from CQL to CCL . These utilities have
633 prefix cql_to_ccl defined in cql.h.
635 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
636 lead to memory heap corruptions when ICU utilities were in use.
640 Make compilation work without Libxml2.
642 yaz-client: remove redundant blanks in display of searchResult-1 term
647 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
648 resulting CQL node (tree) in a new node CQL_NODE_SORT.
650 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
651 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
652 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
653 Note that the CQL sortby spec is only converted when the GFS is already
654 converting from CQL to RPN (cql2rpn element).
656 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
657 specify whether to collapse delimitors or not. The existing nmem_strsplit
658 do collapse (collapse parameter = 1).
660 Windows installer: For NSIS, set InstallDir depending on x86/x64.
662 Rename internal func yaz_use_attribute_create. While non-static, this
663 function is not declared in a public header.
667 Add -lCrun when linking with ICU on Solaris.
669 More quicks character set conversions for OPAC records.
673 fix problem with record_render: records were converted (character set
674 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
678 SRU: add methods for handling DADS SRU-proxy facets.
680 Separate OPAC record character set for ZOOM_record. yaz_record_render
681 allows a character set given as charset=from/opacfrom,to where 'from' is
682 the character set of a bibliographic record, 'opacfrom' is character set
683 of OPAC record and 'to' is the target character set.
687 yaz-client: show may XML format records. Command show followed by 'format'
688 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
691 src/stemmer.c: Avoid using unnamed union. It is not supported by some
694 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
697 Update yaz.spec to operate on both SLES11 / Centos 5.5.
699 RPM: Release includes 'indexdata' name. Use indexdata in release name so
700 this package can be distinguished from other vendors.
702 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
703 as determined by configure
705 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
707 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
708 returns no error and no record, the present request is considered
709 partial (only a subset of the records could be returned by backend), and
710 so it is appropriate to set Present Status to partial-4.
714 Move yaz-config man pages to section 1.
716 More documentation about Solr.
718 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
719 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
720 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
721 peers on some Linux systems. However, in general that does not work
722 so YAZ can not rely on that to work. Debian changed behavior in this
723 respect from Debian lenny to Debian squeeze (still testing as of Oct
725 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
727 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
731 Fix yaz-config output: echo_source not set correctly by configure.
735 Solr Web Service support for yaz-client and ZOOM.
737 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
739 --- 4.0.12 2010/08/17
741 Z39.50 facet support. Facet specifications are passed for search in
742 other-information with ASN.1 as defined in facet.asn and OID
743 .10.1000.81.5 . Facets are expressed as an Attribute list as known
744 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
745 3 is limit (number of entries to get in response). yaz-ztest returns
746 dummy facets if a client asks for them.
748 --- 4.0.11 2010/07/09
750 CCL fixes: bug 2895 and bug 3539.
752 GR1-display: add comma in display - was removed by mistake in
755 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
757 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
759 --- 4.0.10 2010/06/18
761 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
762 result set from a connection. The result set will be on its own
763 thereafter; no operations on it will perform retrievals from a target.
764 Only cached copies are returned.
766 ZOOM C:fix case for HTTP servers responding with Connection:close.
767 Ensure that if there is a current task it is resumed (like fetching
768 more records in a result set) . Bug #3484.
770 PQF parser: use odr_atoi for Odr_int (not atoi)
772 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
773 values that contain any non-digits are treated as string attributes
774 (previously decoding only checked for leading character ([0-9]). PQF
775 encoding: attribute string values are not surrounded by double-quotes.
779 New utility for managing threads - thread_create.h.
781 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
782 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
783 but YAZ' implementation do.
785 Fixes for yaz_cond-functions on Windows 7.
787 DLL export more symbols.
789 zoomsh: show record do NOT render opac.
791 Remove *.la files from Debian and RPM packages.
795 Debian package libyaz-dev depends on libgnutls-dev again (was
796 removed in YAZ 4.0.6, but due to Libtool it is still needed
797 even though yaz-config do not list libgnutls libs).
799 ZOOM: Use only one WRBUF for returning string results for
800 ZOOM_resultset. Reduces memory usage for ZOOM in general.
802 ZOOM: ZOOM_connection do not use a shared pointer to
803 ZOOM_resultset after ZOOM_resultset is destructed by
804 user. Reverts to YAZ 4.0.4 behavior.
808 record-conv: fix problem with at least one XSL conversion -
809 due to probably incorrect usage of XML XSL documents.
813 Fix yaz-config for static mode and the use of SSL (gnutls).
817 Forward decl timeval struct in mutex.h and gettimeofday.h.
819 yaz-config: fix 'static' mode linking.
823 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
824 are wrappers for pthreads or Windows. For Windows these are put in
825 a separate DLL: yaz_cond4.
827 libyaz.la (whole source) is compiled with thread. If thread support
828 is enabled enabled, all source of YAZ is compiled with treading support.
829 This allows core utilities such as yaz_log to use thread facilities.
830 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
831 thread utilities. This commit moves mutex utilities (mutex.c) from
832 libyaz_server.la to libyaz.la.
834 yaz-json-parse displays leading text until error.
838 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
839 patch from Giannis Kosmas.
841 SRU: no longer URL encode SRU database. The URL for an SRU server is
842 a URL and such is alreeady encoded - at least when given with leading
843 http:// or https://. This reverts behavior to YAZ 3.0.50.
845 Support for new MARC XML notation TurboMARC which like MARCXML is a
846 complete representation of MARC/ISO2709.. This one, however, is more
847 compact and allows for faster processing with XSLT. TurboMARC can be
848 used in the marcdisp.h API, from the yaz-marcdump utility and from
851 yaz-ztest can be configured - via the database - to perform certain
852 delays when it performs operations search, present and single record
853 fetch. This allows testers to make yaz-ztest act as a real or even slow
854 Z39.50 server. Refer to the yaz-ztest man pages for details.
858 wrbuf_destroy allows NULL WRBUF passed to it.
860 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
862 Add ZOOM_connection_close.
864 No fixed size buffers for ZOOM shell - bug #3257.
866 tstodr: make it work on s390 platform.
868 New icu iterator-functions. The new icu_iter-functions makes it possible
869 to use ICU chains from many threads.
871 yaz-client: better syntax check for show command.
875 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
878 New simple local-file XML include facility which allows file glob-patterns.
879 Refer to yaz/xml_include.h.
881 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
884 ZOOM_record_get supports new parameter "format" which makes it format XML
887 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
888 JSONText in ECMA-262) is JSONValue, not JSONObject.
892 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
893 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
895 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
896 POSIX/Unix builds .so with major version 4.
898 Remove old LOG_-defines from log.h. They have been obsolete and
899 undefined by default for the last 5 years.
901 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
903 GFS: Remove socket (int *fd) from search_rr handler. The socket
904 descriptor ptr is a facility that allowed a search handler to supply
905 a socket which would serve as a callback - when search was complete.
906 This facility has now been in use for years.
908 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
909 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
910 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
911 returns 'const char *' rather than 'char *. The returned string is
912 read-only and should not be modified by applications. COMSTACK cs_close is
913 now a void function - it no longer returns int. No applications check for
914 the value and the implementations has always returned 0.
916 ZOOM: use size_t for scan hit counts and str size. Functions
917 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
918 occ (hit count) and len (string length) are now of type size_t pointer
919 rather than int pointer. This is to be able to represent large hit counts
920 and to also just to use the proper type for string length (strlen result).
922 New JSON parser. Refer to include/yaz/json.h .
924 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
925 Used to be int in some cases. Many wrbuf_-functions used to return an int
926 indicating some length.. These return values were never used. And so they
929 ODR: odr_malloc, odr_total now takes size_t for size.
931 clone_z_type: fix leak; occurred for encoding failures.
933 --- 3.0.52 2009/12/03
935 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
936 bug was introduced in 3.0.51.
938 --- 3.0.51 2009/12/02
940 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
942 tcpip comstack: fix leak for getaddrinfo.
944 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
945 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
946 Decoding of SRU "path" database is performed by private function
947 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
948 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
950 yaz-client: honor base command for SRU. Change when database setting
951 is applied for SRU and ensure it is kept when a connection is reset.
952 Change also the way errors are displayed or SRU (decoding of packages).
954 --- 3.0.50 2009/11/02
956 Add support for extra request / response data for SRU codecs and GFS.
957 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
958 for extra data response buffer and length. For the GFS, both request
959 and response data (XML) is carried in extra_args and extra_response_data
960 for the search handler. Patch by Ko van der Sloot.
962 ZOOM: For queries that cannot be converted to the specified rpnCharset,
963 ZOOM now returns a diagnostic on the client-side ('invalid query' /
964 10010). This fixes bug #2113.
966 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
967 cmdfile included a 'quit' command that would result in a memory violation.
969 --- 3.0.49 2009/10/01
971 Make a number of functions defined in xmlquery.c static. These have
972 never been declared in a public header file (yaz/xmlquery.h) and was
973 made public by mistake.
975 Improve speed of character conversions (iconv utilities). This makes
976 conversions from MARC-8 faster.
978 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
979 unless type desired is "raw". This will prevent type "xml" from
980 returning ISO2709 .. Which obviously can not be XML parsed.
982 Fix memory leak in ZOOM that would occur if option apdulog was used
983 on a re-used connection.
985 Frontend server logs HTTP requests.
987 Frontend server now sends Z39.50 close when it times out (sesssion has
988 been idle for too long). Versions 2.0.30 and earlier also sent close.
989 But due to a mistake this was disabled in all versions after that, i.e.
990 the server would just close the socket immediately.
992 yaz-client emits a better message when receiving an unrecognised
993 userInformationField.
995 Skip zero-length subfields when decoding ISO2709. This rare case happens
996 if a record has two FS characters in a sequence. Without this patch
997 there would be a reference beyond char array in using_code_len fragments
1000 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1002 --- 3.0.48 2009/08/28
1004 The show command offered by the zoomsh command now takes a 3d optional
1005 parameter type which is what is passed to ZOOM_record. If the type
1006 argument is omitted, "render" is used.
1008 RPN to CQL conv may use USE string attributes (bug #2978).
1010 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1012 --- 3.0.47 2009/07/08
1014 Function yaz_xml2query allows a diagnostic element in the PQF XML
1015 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1016 code and additional info respectively.
1018 The BER BOOLEAN is now the integral type Odr_bool which still happens
1019 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1020 typedef'd to Odr_int. This is still an integral 'int', but it may be
1021 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1022 ASN-1 compiler as well as programs has been updated to use the new types.
1024 --- 3.0.46 2009/06/08
1026 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1027 only the bibliographic record was rendered. For type=opac, an OPAC
1028 record is only returned if it is present.
1030 iconv: small fix for encoding of advancegreek.
1032 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1034 yaz-client: option auto_reconnect=on really reconnects.
1036 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1038 server: avoid null ptr ref for for yaz_poll errors.
1040 build: fix RPM build for RHEL 5.3.
1042 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1044 --- 3.0.45 2009/03/31
1046 Fixed bug #2709: TCP connect returns Invalid argument.
1048 Fixed compilation for mingw.
1050 Honor charset for raw records (ZOOM_record_get).
1052 Fixed use of errno for threaded mode that was seen on Solaris 10.
1054 Fixed argument passing with blanks in value for Windows Service.
1056 Disable YAZ' own log rotate by default (no 1 GB limit).
1057 The variable l_max_size which specifies the log file limit is set to 0
1058 (DISABLED): This is due to the fact that YAZ is most often deployed using
1059 logrotate. Also YAZ can not perform log rotate because of unsufficient
1060 permissions (setuid).
1062 --- 3.0.44 2009/02/17
1064 List supported encodings in man page for yaz-iconv.
1066 Fixed missing SSL libs for --libs output
1068 Re-established OID record syntax application-xml. Nobody should use it
1069 but we don't want to change soname because of this symbol being absent.
1071 --- 3.0.42 2009/02/02
1073 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1075 Added member named_result_sets for init handler struct for the GFS. This
1076 allows a server to disable named result sets.
1078 Removed OID record syntax application-xml.
1080 Added support for rule-based transliterator for ICU wrapper of YAZ.
1082 Fixed bug #1902: yaz-icu XML output.
1084 Make YAZ checks Emacs friendly.
1086 BITSTRING value shows value. Bug #2346.
1088 ISO2709 decoding: skip control characters from indicator data.
1090 Omit sort key by default in yaz-icu's output.
1092 Allow combined single char options (again) for YAZ' options function.
1094 Utility yaz-marcdump got option to display YAZ version (-V).
1096 Allow YAZ to use ICU 3.4.
1098 Added new ICU test case which illustrates removal of diacritics.
1100 --- 3.0.41 2008/12/29
1102 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1104 --- 3.0.40 2008/12/29
1106 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1109 Fixed bug #2352: yaz-marcdump crashes for certain record.
1111 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1113 Added support for Danmarc2 to UTF-8 conversion.
1115 Added support for ISO5426 to UTF-8 conversion.
1117 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1118 implementation version.
1120 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1122 --- 3.0.38 2008/11/10
1124 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1125 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1127 ZOOM C now interprets databaseName option for ZOOM connection as path
1130 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1132 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1134 Dummy Libxml2 types no longer defined in headers of YAZ'.
1136 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1139 --- 3.0.36 2008/09/26
1141 Various ODR chapter fixes.
1143 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1145 Added missing source for Windows compilation, mutex.c.
1147 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1149 For SRU connections in ZOOM all records up to "count" are now fetched.
1151 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1152 in Windows due to bad error handling for Libxml2.
1154 Added facility for sending arbitrary records (ASN.1 any) using
1155 ZOOM C's Extended service update. Patch by Sam Reynolds.
1157 New options for ZOOM C's connection, logapdu which makes ZOOM log
1160 --- 3.0.34 2008/06/18
1162 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1164 --- 3.0.32 2008/06/12
1166 Fixed memory violation that could occur when decoding UTF-8. This bug
1167 was only present in 3.0.30 of YAZ.
1169 --- 3.0.30 2008/06/06
1171 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1172 GNU TLS is used by default (if found).
1174 yaz-ztest returns OPAC records if a client asks for OPAC.
1176 Improved speed of MARC-8 encoding.
1178 Added support for lossy and loss-less MARC-8 encoding.
1180 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1182 Added new Windows Service wrapper (sc).
1184 yaz-client's itemorder command may now send a file.
1186 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1188 Added new function yaz_log_xml_errors.
1190 Allow (but warn) unknown XML attributes in MARCXML parsing.
1192 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1194 The UTF-8 to MARC-8 conversion now uses a different set of characters
1195 for Greek symbols. Bug #2120.
1197 --- 3.0.26 2008/02/21
1199 Added yaz_daemon (daemon.h).
1201 Fixed bug #2068: pkg-config trouble
1203 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1205 --- 3.0.24 2008/01/28
1207 Document --with-xml2 option.
1209 Added OPAC XML XSD (etc/opacxml.xsd).
1211 Allow glob mask for name attribute in retrieval element for the
1212 generic frontend server's retrieval facility.
1214 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1215 except POLLIN/POLLOUT.
1217 Fixed error handling in cs_listen. Bug #2037.
1219 --- 3.0.22 2008/01/20
1221 Fixed version in yaz/yaz-version.h.
1223 Fixed bug #2027: Crash when closing connection.
1225 Changed configure so that ICU support is only enabled if only ICU
1226 and Libxml2 is available (because the ICU chain is XML based).
1228 --- 3.0.20 2008/01/15
1230 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1231 is built. Only this DLL depends on the ICU runtime.
1233 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1234 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1236 Changed license of CCL module to 'Revised BSD'. After consultation with
1237 remaining members of the original EUROPAGATE consortium, we are re-issuing
1238 the CCL module without a separate license. The software was developed by
1239 Index Data as part of a research project. The special license was included
1240 to help feed usage information back to the project consortium to support
1241 project evaluation. At this time, the project consortium has long-since
1242 disbanded, and the majority of the original principals have retired. At the
1243 same time, we have significantly modified the software during the following
1244 years, to the point where very practically no original code remains. To
1245 simplify re-use of the software, we have contacted those members of the
1246 consortium who could be reached, and agreed to re-issue the module as a
1247 proper part of the YAZ package.
1249 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1251 CQL closer to being version 1.2 compliant. CQL also allows free-form
1252 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1255 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1256 bug could make Extended services handling crash in the ZOOM layer. This
1257 bug was only present in YAZ 3.0.18.
1259 --- 3.0.18 2007/12/19
1261 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1264 yaz-marcdump reads and writes collection wrapped records.
1266 Handle OPAC for record conversion module.
1268 Fixes for ICU wrapper.
1270 Allow ICU libs to be controlled with --with-icu .
1272 --- 3.0.16 2007/11/12
1274 Added yaz_poll which is a wrapper for select/poll. When poll is available
1275 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1276 sockets to be in use.
1278 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1279 functionality through an XML based configuration (ICU chain). This system
1280 is useful for search facilities such as Pazpar2 and Zebra that needs to
1281 perform tokenization of indexed material. The ICU code in a separate
1282 library libyaz3_icu.a.
1284 Added HTTP tunnel facility for COMSTACK, bug #1752.
1285 This is a facility that allows a Web proxy, such as squid, to tunnel
1286 Z39.50 traffic. This facility is "transparent" to must applications
1287 using YAZ. It's enabled by using pseudo transport connect: followed by
1288 the proxy address, followed by command, then follwed by he regular
1289 "virtual" addresss. For example,
1290 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1292 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1294 --- 3.0.14 2007/09/21
1296 Fixed bad memory reference in ZOOM_record - cuased by member not being
1297 initialized. This was a problem only in YAZ 3.0.12.
1299 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1300 fields were not removed.
1302 Changed the way C code is generated from codetables.xml. Made a MARC-8
1303 conversion trie for each characterSet section rather than codeTable.
1304 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1305 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1307 --- 3.0.12 2007/09/12
1309 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1310 from ZOOM_record_error).
1312 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1314 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1316 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1318 Better SRW-to-Bib-1 diagnostic mapping.
1320 ZOOM C and yaz-client announces SRU version 1.2 by default.
1322 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1325 Fixed in yaz_sru_decode to allow other version than 1.1.
1327 --- 3.0.10 2007/08/22
1329 Added support for SRU scan for ZOOM.
1331 Added support for the use of the older versions or Extended Service
1332 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1333 set to the version , 1=first, 2=second, 3=third. The third version is
1334 what ZOOM C has used so far. And that, obviously, is the default.
1336 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1337 therefore in Zebra and in SimpleServer-based applications). The new
1338 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1339 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1340 which is passed into the back-end search callback function.
1342 Added support for HTTP Basic authentication in clients: the SRU/W
1343 codec encodes the username/password elements of the PDU structure
1344 appropriately, and these may be set using the "user" and "password"
1345 options in ZOOM-C applications (the same options that are used for
1346 Z39.50 authentication).
1348 --- 3.0.8 2007/06/25
1350 Fixed bug #1208: SSL appears to be broken in ZOOM.
1352 Fixed bug #1206: Libxml2 include path weirdness.
1354 Added oid_name_to_dotstring.
1356 Allow elementSetName to be specified for ZOOM C record update.
1358 Allow waitAction to be specified for ZOOM C based for Extended Services.
1360 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1361 syntax OID. Bug introduced in YAZ 3 series.
1363 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1365 --- 3.0.6 2007/06/06
1367 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1368 directory. yaz-client now reads commands from file given by option -f
1369 if specified; then tries to read .yazclientrc in current directory.
1370 Failing that, it reads .yazclientrc from user's home directory.
1372 Added support for correlationInfo Note and ID for Record Update via
1375 Added yaz-client command querycharset which specifies character set for
1376 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1377 (termListAndStartPoint).
1379 Charset ISO5428:1984 is an alias for ISO5428-1984.
1381 Implemented a way to perform scan in a result set using Z39.50. This
1382 is achieved by attaching the result set name in the characterInfo
1383 (type InternationalString) of OtherInformation in the Scan Request PDU.
1384 The result set is identified in the otherinformation by the new OID:
1385 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1386 This allows for scan in result set and faceted search . Zebra did some
1387 of this in the APT term using attribute type 8 and value being result
1388 set. Using the OtherInformation approach for this is cleaner and easier
1389 to work with in proxies and the like. This facility can be used in
1390 yaz-client using new command setscan which takes a result set as first
1391 argument, start position (APT) as second.
1393 Changed decoding of SRU XML packed records to deal with servers that
1394 have recordData with XML data with multiple root nodes. Also make
1395 comparison for recordPacking case insensitive. Again, one server
1396 returns "XML" where others return "xml".
1398 For SRU responses allow Content-Type application/xml as well as text/xml.
1400 --- 3.0.4 2007/05/21
1402 Fixed bug in character set conversion of BER strings. Bug introduced
1405 --- 3.0.2 2007/05/08
1407 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1409 For OID class, use oid_class consistently.
1411 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1414 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1415 character set for bibliographic information interchange". By Giannis Kosmas.
1417 Added documentation on new OID API.
1419 --- 3.0.0 2007/05/02
1421 Changes to generic frontend server interface: added new member
1422 'query_charset' for bend_initrequest structure. A backend init handler
1423 should set this member to its native character set for query terms.
1424 When defined, the frontend server logic will announce this character set
1425 to a client if the negotiationModel bit is set by the client. All server
1426 implementors are encouraged to specify this. If a backend server does not
1427 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1429 Added CCL utility to remove terms (stop words) from resulting RPN
1430 tree. This is handled by functions with prefix ccl_stop_words_ .
1432 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1433 terms in RPN queries.
1435 Clean-up the CCL API. Moved some internal structures from ccl.h to
1436 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1437 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1438 This is replaced by ccl_parser_find_str which takes a string instead.
1440 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1441 libyaz.la is the core of YAZ except the generic frontend server and
1442 does not depend on POSIX threads anymore. libyaz_server.la is the
1443 generic frontend server facilities and uses POSIX thread functionality
1444 if available. The libyaz.la no longer depends on POSIX threads because
1445 the number of global structures is limited. NMEM no longer re-uses blocks
1446 between threads ; it simply free's memory immediately but allocates in
1447 "large" chunks as usual. We don't expect any performance penalties
1448 because of this. The yaz_log system is still using a global log_level so
1449 caution must be taken when modifying it with yaz_log_init_.. +
1450 yaz_log_mask_str. This, however, should not cause any trouble because
1451 these functions are called during initialization of application code
1452 anyway. `yaz-config --libs server` returns libs for server applications;
1453 `yaz-config --libs` returns libs for non-server applications.
1455 New OID database - with public definitions in oid_db.h. Removed old OID
1456 database including the head oid.h and definitions such as enum oid_value
1457 and struct oident. The new OID database uses the same string names as
1458 before but the 'protocol' is gone. There are now only two representations
1459 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1460 converts from string to OID; functions with prefix yaz_oid_to_string
1461 converts the other way.
1463 Change to emit_term() in CQL-to-PQF query translation: when a term has
1464 the /regexp relation modifier, do not process it for leading and
1465 trailing "^" and "*", which have quite different meanings in regular
1468 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1469 write handlers no longer carries a 'last' parameter. This will make
1470 yaz_iconv flush "less" characters. A flush is performed by call to
1471 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1473 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1474 removed, because function yaz_query_to_wrbuf does the same.
1476 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1477 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1479 Deprecated MARC utility functions removed.
1481 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1484 Branch split: YAZ_2_1_55_branch
1486 --- 2.1.54 2007/03/16
1488 Fix to ZOOM-C so that transparent reconnection is properly handled on
1489 connections that are in asynchronous mode.
1491 Fixed compilation on OpenBSD 4.0.
1493 Large strings in GRS-1 records are now properly displayed in yaz-client.
1495 Added character conversion support for "advancegreek"; based on patch from
1498 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1499 sequence is met. Before the error was not set so it would be unknown.
1501 Adjust yaz-marcdump MARC reader so that it skips until record separator
1504 --- 2.1.52 2007/03/07
1506 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1507 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1508 fd_set structure used as a bitmask for the FDs to be selected on.
1510 Using ACX_PTHREAD macro to check for POSIX threads.
1512 Fixed have-vsnprintf check.
1514 --- 2.1.50 2007/02/23
1516 Fixes for configure on BSD. Bug #900.
1518 Added snprintf/vsnprintf wrappers for systems that don't have
1519 limits (heavens forbid).
1521 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1522 created before all previous tasks were completed and removed from the
1523 task queue, the new task could be removed by a mistake.
1525 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1527 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1529 Fixed bug #832: Problem with MARC/charset in yaz-client.
1531 Fixed bug #668: save command line history for yaz-client.
1533 Fixed bug #830: pkg-config support.
1535 --- 2.1.48 2007/01/23
1537 Extended ZOOM result set options with two options that may be read by
1538 a client: resultSetStatus and presentStatus with values as specified for
1540 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1542 Fixed bug #827: Using SSL fails on Debian etch.
1544 Fixed bug #826: Weird looking chars for set of MARC records.
1546 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1547 that is treated as an ItemOrder with itemRequest being an XML document
1548 external. The value of "doc" is the content.
1550 Extended the GFS search facility. New member of bend_search_rr
1551 'estimated_hit_count' signals that hits is known to be an estmate
1552 (higher or lower than real hit count). New member 'partial_resultset'
1553 signals that the search was partial (hit count is lower or equal than
1554 real hit count). For Z39.50, the information is stored in resultSetStatus
1555 member of SearchResponse APDU. For SRU, the information is signalled
1556 via SRU diagnostic 59: "Result set created with valid partial results
1559 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1561 --- 2.1.46 2007/01/13
1563 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1565 Added ZOOM_connection_peek_event.
1567 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1568 the following new functions:
1569 ZOOM_event_nonblock, ZOOM_connection_process,
1570 ZOOM_connection_get_{socket,mask,timeout},
1571 ZOOM_connection_fire_event_{timeout,socket}.
1572 The existing blocking event handler, ZOOM_event, is a wrapper for the
1573 + blocking ZOOM_event_sys_{poll,select}.
1575 Implemented function ccl_xml_config which parses XML version of CCL
1576 configuration (bug #798).
1578 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1580 Added timings utility (yaz/timing.h)
1582 --- 2.1.44 2007/01/03
1584 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1587 Fixed bug #779: Rotation of apdu.log fails.
1589 Fixed for character set conversions:
1590 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1591 Honor G1 set in MARC-8 decoding.
1593 --- 2.1.42 2006/12/17
1595 Fixed bug #775: char conversion does not handle Alternative UTF-8
1598 Implemented function yaz_marc_read_line which parses MARC line format
1599 records. There is a wealth of formats out there. So far, this function
1600 reads line records produced by yaz_marc_write_line.
1602 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1603 more generic and easier to remember(!) options: -i format and -o format
1604 which specifies input format and output format respectively - where
1605 format is one of "marc", "marcxml", "line", "marcxchange".
1607 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1608 does not print anything except warnings for records.
1610 For yaz-marcdump, added support for MARC split into files (-s) with a given
1613 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1614 spec, at http://www.loc.gov/standards/sru/record-update/
1615 This has changed the binary layout of the following structs:
1616 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1617 bend_update_rr . Patch by Ko van der Sloot.
1619 Added GFS utility function bend_assoc_is_alive which returns 1 if
1620 association is still alive (client is connected); 0 otherwise (client
1621 closed connection). This allows busy servers to stop working for
1624 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1625 been a separate piece of software. This version of ziffy has been modified
1626 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1628 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1630 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1631 Client code may now interrogate options such as "init_opt_sort" to
1632 find out whether the server claims to support various options.
1634 --- 2.1.40 2006/11/27
1636 Added utilities yaz_{set,get}_esn to set/get element set name from
1639 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1640 of YAZ and has been so since YAZ 2.1.10.
1642 Implemented ZOOM_record_error which returns error information for
1643 record (surrogate diagnostic).
1645 --- 2.1.38 2006/10/31
1647 Updates for SRU Update by Ko van der Sloot:
1648 1. Changed name from "operation" to "action"
1649 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1650 versions in the code, marked as 'backward compatible'.
1651 3. Added diagnostics for SRU Update.
1653 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1655 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1657 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1659 For GFS, fixed problem with SRU diagnostic 'First record position out of
1660 range' being issued for 0 hits.
1662 zoomtst10 part of Windows Build.
1664 --- 2.1.36 2006/10/13
1666 Implemented yaz_filepath_comp which splits a path into file path
1667 components (required by Zebra 2.0.3+).
1669 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1670 BSD inspired license until now so this should not have any real impact on
1671 anybody. See http://www.opensource.org/licenses/bsd-license.php
1673 Fixed bug #687: Missing log lines.
1675 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1678 Fixed bug #689: SRU diagnostics to be added.
1680 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1681 whether a connection is idle (no more work do do).
1683 --- 2.1.34 2006/10/04
1685 Change type of optval from long to int for invocation of setsockopt with
1686 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1688 Added support for specifying the max log file size for the Generic
1689 Frontend Server. The size is given with option -r.
1691 --- 2.1.32 2006/09/21
1693 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1695 --- 2.1.30 2006/09/17
1697 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1700 Fixed bug in Generic Frontend Server that could cause a server to stop
1701 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1703 For the generic frontend server, the maximum record size is used as maximum
1704 size of incoming packages (SRU + Z39.50). The value until was previously
1705 only used in Z39.50 Init negotiation and, later, in a session controlled
1706 sizes of records returned. This is controlled using -k option. It can be
1707 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1709 --- 2.1.28 2006/09/04
1711 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1714 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1716 New option for yaz-marcdump -lpos=value which allows setting a portion
1717 of MARC header to a certain value.
1719 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1721 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1722 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1724 --- 2.1.26 2006/08/15
1726 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1729 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1731 --- 2.1.24 2006/08/08
1733 Fixed MARC ISO2709 encoding routines to deal with character set
1736 Minor changes to GFS logging. Database included in search request log
1739 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1740 cached/multiple records.
1742 Shared libraries are built by default on Unix+configure.
1744 Changed cql2pqf transformation to use a different evaluation order. The
1745 new order is: always, relation, structure, position, truncation, index
1746 and relationModifier. Old order was: always, relation, relationModifier,
1747 structure, index, position, truncation. Note that the the latter ones
1748 override former ones for identical attributes.. The new scheme means that
1749 it is possible to override any existing attribute with a relationModifier.
1750 And also that it is possible to override everything for the index rule
1751 (except the ones listed in relationModifier). No order is perfect but this
1752 one, we believe, covers more real cases.. The "always" should have been
1753 called "default", since the attributes there can be overridden with all
1756 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1757 compilation phase, but also for yaz-config --cflags output. This allows
1758 us to have public headers with Libxml2 stuff in them . It should also,
1759 eventually, make Libxml2 checks redundant in packages using YAZ, such
1762 --- 2.1.22 2006/06/15
1764 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1765 stored in uri, message and details.. Previously diagnostics were stored
1766 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1767 compatibility.. but he's probably the only one affected, so.
1769 Added support for CCL, compiled on the client side, in ZOOM-C. This
1770 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1771 input; the resulting query objects can be used for for searching with
1772 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1774 YAZ' configure searches for OpenSSL by default.
1776 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1777 SL_CTX_use_certificate_file. See
1778 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1779 for more info. Thanks to Ko van der Sloot.
1781 --- 2.1.20 2006/06/02
1783 Bug #600: SRU GET, POST support for yaz-client. Introduced
1784 command 'sru' which selects method SOAP/GET/POST.
1786 Allow missingValueAction to be specified for the sortspec string -
1787 function yaz_sort_spec. By default, the missing value action is null.
1788 Use ! to specify "abort". Use = followed by stringvalue to specify default
1791 Ensured that Present-handler (if defined) is called in GFS before any call to
1792 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1793 searchRetrieve requests.
1795 Documentation for YAZ is now based on the Docbook XML/XSLT using
1796 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1797 is no longer depending on jade/openjade or docbook-to-man scripts.
1798 PDF is no longer part of the distribution - but can optionally be
1799 made using DSSSL/jadetex or FOP.
1801 Added retrieval handling support in Generic Frontend Server to support
1802 conversion between MARC/XML as well as XSLTtransforms. See
1803 etc/yazgfs.xml for an example.
1805 Added Authentication support to Generic Frontend Server in SRU
1806 mode. Authentication using HTTP Basic is supported, as is the use
1807 of 'x-username' and 'x-password' parameters in the request itself.
1809 Added support for a new character set MARC8s identical to MARC8 except
1810 that it converts combined characters to single Unicode characters in the
1811 Latin-1 range (when possible).
1813 --- 2.1.18 2006/04/24
1815 ASN.1 compiler 0.4: generates brief Doxygen file header for
1816 generated .h/.c files.
1818 Utility yaz_iconv now supports conversion to MARC-8.
1820 New facilities for the MARC module. The reading - and writing of
1821 content are separate methods for the yaz_marc_t handle. The following
1822 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1823 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1824 format). Write functions have prefix yaz_marc_write_.. The existing
1825 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1826 available. Removed support for OAI-MARC and simplexml (not the
1827 simplexml from PHP5).
1829 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1830 to be returned for this connection.
1832 --- 2.1.16 2006/03/31
1834 Allow multiple languages and charsets to be specified with
1835 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1836 negcharset iso-8859-1,utf-8
1838 Translation of proximity nodes from CQL into PQF now works.
1840 Moved to automake 1.8, 1.9.
1842 Added function yaz_log_set_handler which allows a log handler to be
1843 installed. This handler will be called for all log messages. Output
1844 to file is also produced; but that can be disabled by passing NULL
1845 fname to yaz_log_init_file.
1847 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1849 For SRW (including GFS), accept application/soap+xml as content-type
1852 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1853 produces NO stylesheet reference even if a default stylesheet is specified
1856 --- 2.1.14 2006/03/14
1858 Updated Windows package to include yazd.dll + yazd.lib for the
1859 Development component.
1861 If the environment variable YAZ_LOG is set, then it is used as a
1862 string indicating the default level of logging to use if not
1863 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1864 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1865 used as before. So, for example, to omit warnings from YAZ logging,
1866 export YAZ_LOG=-warn
1868 cql_transform() now map structure and other attributes before indexes,
1869 so that index-specific structures and other attributes can override
1870 defaults. So now a combination of mapping specifications such as:
1872 index.dc.date = 1=date-modified 4=5
1873 does the right thing.
1875 cql_transform() now also respects the "always" mapping specification,
1876 which establishes an initial set of attributes to be used for all
1877 terms except where overridden by more specific attributes associated
1878 with the index, relation or modifier.
1880 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1881 which mode to use; one of "post", "get" or "soap" (SRW, default).
1883 Fixes for yaz_iconv routines: changed trie-based character set conversions
1884 to use only non-negative values for bit fields due to Sun's C compiler not
1885 supporting negative values.
1887 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1888 sequences where not read correctly. Fix by Rustam Usmanov.
1890 Updated win/makefile to use options, settings which makes things
1891 compile with VS C 2005.
1893 --- 2.1.12 2006/02/01
1895 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1897 In ZOOM socket code, use select instead of poll on MacOSX.
1899 ZOOM-C now support client-side compilation of CQL into RPN that is
1900 sent to the server, enabling CQL to be used against all Z39.50
1901 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1902 ZOOM_query object, and submit it using ZOOM_connection_search().
1903 The CQL-to-RPN translation uses a configuration file, the name of
1904 which must be specified in the Connection's "cqlfile" option.
1906 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1907 function, which takes as its start-term parameter a ZOOM_query object
1908 (which may have had either CQL or RPN set into it).
1911 --- 2.1.10 2005/11/29
1913 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1914 GFS to support this as well. Backend handler, bend_srw_update, does the
1915 update work. Code contributed by Ko van der Sloot.
1917 Allow retrieval of Search Result-1 information in ZOOM by the use of
1918 options that are attached to a result set. ZOOM documentation updated
1921 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1922 UTF-8 conversion. Patch by Raj Patel.
1924 Added option -m to GFS to control formatting of timestamps in log file.
1926 Added 'exit' as synonym for 'quit' in yaz-client
1928 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1929 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1930 for the new members. Patch by Ko van der Sloot.
1932 Added support for SRU POST. It is supported for content-type
1933 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1935 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1936 Instead make the library libyaz.la multi-threaded. Threading as a whole
1937 can still be disabled by configure option --disable-threads. Previosly,
1938 with older GLIBCs there were problems with MT libs under Apache. This
1939 has now been fixed a long time ago.
1941 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1944 CQL module modified to be case insensitive for relations/indexes/operations.
1946 Fixed bug in CQL transform code: incorrect value relationModifieder
1949 Added 'show all' command for yaz-client which retrieves all results
1952 Added new yaz-client, xmles, which takes a (private) OID and
1953 a document to be sent as an extended service request.
1955 Describe new yaz-client commands wait_response and set_auto_wait.
1957 Increase TCP/IP listener backlog from 3 (which I am guessing was
1958 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1959 that the socket will queue as many incoming connections as it's able
1960 to handle ongoing connections. In other words, it will never now
1961 refuse a connection that it would be able to handle merely because
1962 it's not got around to accepting() enough of the pending connections
1963 yet. This is the behaviour anyway under Linux, where the listen()
1964 argument is ignored; but not under BSD and on systems such as
1965 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1966 YAZ-based servers should now be uniform across operating systems in
1969 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1970 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1971 This allows yaz-marcdump to read large MARC batches (>2 GB).
1973 Modified all YAZ source files - except the source which is auto-generated
1974 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1977 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1978 corresponding to the existing *_setl() function. These allow option
1979 values containing arbitrary valuues.
1981 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1982 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1983 except that it returns an indicator of whether or not the sort
1984 criterion was accepted (0 for OK, -1 for invalid).
1986 --- 2.1.8 2005/06/07
1988 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1989 MARC output rather than returning "new" buffer.
1991 yaz-client warns about unknown init options.
1993 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1995 --- 2.1.6 2005/05/24
1997 Added support for SRW sort in Generic Frontend Server. Patch
1998 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1999 sortKeys - or NULL if none is provided.
2001 Fixed bug #307: It was impossible to specify indefinite/no timeout
2002 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2005 Added support for multiple languages and charsets to be specified in
2006 ZOOM. Each charset/language is separated by a blank. If negotiation is
2007 in effect in init-response, Option
2008 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2009 Code based on patch by Vasiliy Osadchuk.
2011 Fixed bug #306: infinite recursion that occurred when calling
2012 yaz_log_level_init as the first call (before other log level or
2015 Fixed bug in scan handling in front end server: if preferred-Position-In-
2016 Response was non-present, a NULL pointer referece was performed.
2018 --- 2.1.4 2005/04/26
2020 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2021 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2022 now defined for all those error codes. So instead of putting 109 in
2023 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2024 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2026 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2029 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2031 Program yaz-client now exits and produces an error message if multiple
2032 Z39.50 servers are specified on the command line (none or one allowed
2035 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2038 --- 2.1.2 2005/03/16
2040 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2042 Fixed bug #272: Preserve spacing for CCL terms.
2044 --- 2.1.0 2005/03/14
2046 Added support for virtual hosts and multiple backend servers for
2047 the YAZ frontend server. The configution is XML based and
2048 support specificition of CQL to RPN mappings and explain information.
2049 See section "Virtual Hosts" in the YAZ manual.
2051 Extended OPAC display utility. OPAC display utility renders
2052 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2053 to supplement yaz_marc_decode_wrbuf.
2055 Fixed a bug in MARC decoder that could caused it to crash for some
2056 invalid MARC records. More diagnostics and warnings where added in
2057 XML output (warnings, etc are stored in comments).
2059 --- 2.0.34 2005/02/08
2061 Fixes for UNIX domain sockets. Bug #261.
2063 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2065 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2066 Added yaz_marc_subfield_str which defines subfield lead string which is
2067 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2068 yaz_marc_endline_str which defines end of fields string used in
2069 YAZ_MARC_LINE format. Default string is newline.
2071 Experimental support for MarcXChange. This format can be produced
2072 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2073 http://www.bs.dk/standards/MarcXchange.xsd
2075 Added yaz-client commands scansize that sets maximum number of
2076 entries to be returned by scan.
2078 --- 2.0.32 2005/01/11
2080 Added support for SRW scan in yaz-client and Generic Frontend Server.
2082 * Added whereInList member to SRW Scan Term.
2084 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2086 Fixed NMEM system to return aligned blocks on the smallest boundaries
2087 that are suitably aligned for all possible types on the particular
2088 architecture YAZ is being built for.
2090 --- 2.0.30 2005/01/04
2092 Fixed numerious warnings that was issued with newer versions of GCC.
2094 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2095 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2098 Make YAZ Generic Frontend Server slightly faster.
2100 Enhance (and reduce) logging for Generic Frontend Server.
2102 Revert YAZ log system so that it flushes every write operation
2103 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2105 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2106 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2107 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2108 will effectively disable old definitions.
2110 --- 2.0.28 2004/11/09
2112 Added yaz_log_time_format which specifies log format using
2115 Added yaz_log_module_level which returns mask for a module. Value
2116 is non-zero mask a if module is enabled; zero if disabled.
2118 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2119 in include/yaz/cql.h.
2121 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2123 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2125 Fixed bug #172: RPM builds does not enable SSL.
2127 Doxyfile.in part of dist. Doxyfile generated by configure.
2129 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2130 are given and the corresponding component does not exist.
2132 Extend CCL documentation in YAZ reference. Describe r=r.
2134 --- 2.0.26 2004/10/01
2136 Fixed MARC->MARCXML conversion to properly deal with
2137 fields, subfields, indicators having non-ASCII characters.
2139 Fixed MARC->MARCXML conversion so that ASCII control characters
2140 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2143 Added YAZ GFS support for conversion from Z39.50 surrogate
2144 diagnostics to SRW surrogate diagnostics.
2146 Bug fix: YAZ GFS did not return schema in explainResponse.
2148 --- 2.0.25 2004/09/30
2150 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2151 now converts recordSchema to elementSetName as well as schema URI.
2153 Fixed bug in COMSTACK that prevented HTTP request packages from being
2156 --- 2.0.24 2004/09/29
2158 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2159 does not require white-space before and after the dash in a range, e.g.
2160 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2163 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2164 due to new GCC removing "redundant" code.
2166 Added yaz-client commands scanpos and scanstep that sets preferred
2167 position and step-size for scan.
2169 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2171 Added CCL utility ccl_qual_buf which parses one or more CCL
2172 spec lines in a buffer.
2174 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2175 of name and value - ignoring empty lines and comments.
2177 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2179 Added odr_get_element_path which returns current element path for an
2180 ODR handle. This utility is useful in error handling or user-defined
2183 Added ODR_PRINT utility odr_set_stream which is is a more generic
2184 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2185 to a write function and pointer to close function. The close function - if
2186 non-NULL - will be called during odr_destroy.
2188 Fixed bug in CCL parser where truncation char was not removed from
2189 right side when truncation=both was in effect.
2191 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2194 --- 2.0.23 2004/08/11
2196 Fix buffer overrun in CQL parser when dealing with proximity (%).
2198 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2199 to UTF-8/UCS conversion is now only based on codetables.xml.
2201 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2203 --- 2.0.22 2004/08/06
2205 Add support for more "commit changes" in ZOOM (uses Extended Services).
2207 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2210 Yet another small fix for configure of SSL.
2212 --- 2.0.21 2004/05/14
2214 Fix SSL libs for configure when --with-openssl=DIR is given.
2216 --- 2.0.20 2004/05/10
2218 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2220 SSL comstack now uses yaz.pem certificate file on server side
2221 by default. Certificate filename can be configured by calling
2222 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2224 Fix bug regarding multiple calls to ZOOM_connection_connect.
2226 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2228 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2229 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2231 ZOOM now allows inspection of X509 peer certificate for verification.
2232 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2234 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2235 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2236 as "modular" but it simplifies things.
2238 Added cs_get_peer_certificate to that returns peer X509 PEM.
2240 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2241 NULL if SSL is unavailable.
2243 Documentation about MARC decoding tools.
2245 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2247 --- 2.0.19 2004/03/30
2249 Rename CHANGELOG to NEWS to follow GNU style packing.
2251 Fix bug with missing initialization of member in init_diagnostics.
2252 This bug affects threaded version of GFS server.
2254 --- 2.0.18 2004/03/20
2256 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2259 Ensure zlib.dll is packed with Windows install.
2261 --- 2.0.17 2004/03/17
2263 Fix encoding of xsd:string to use text instead of CDATA.
2265 Fix endless loop in CQL parser with unbalanced ".
2267 Use a more compact way to store MARC-8 conversion tables.
2269 --- 2.0.16 2004/03/16 Debian only
2271 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2274 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2279 --- 2.0.15 2004/03/01
2281 Another fix for decoding of XML packed records.
2283 --- 2.0.14 2004/02/25
2285 Fixes for Chunked encoding. White space not ignored after length spec.
2287 Update NS and use default NS for SRW diagnostic elements.
2289 --- 2.0.13 2004/02/23
2291 Implement ZOOM_resultset_cache_reset which resets record cache.
2293 Implement ZOOM_resultset_sort which sorts a result set.
2295 Implement chunked HTTP transfer.
2297 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2299 --- 2.0.12 2004/02/16
2301 Added member 'schema' to bend_explain_rr structure so that backend
2302 can specify explain record identifier. Defaults to Zeerex 2.0.
2304 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2306 --- 2.0.11 2004/02/16
2308 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2311 Added init command for yaz-client which sends "extra" init request.
2313 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2314 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2316 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2318 Make ZOOM error code for "invalid query".
2320 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2322 --- 2.0.10 2004/02/05
2324 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2327 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2329 Added option -p <file> to make Generic Frontend Server to write PID file.
2331 Added option -D to put Generic Frontend Server in background on its own.
2333 Make ZOOM C recognize option "password". If unset, "pass" is used
2334 (for backwards compatibility).
2336 Fixed a bug in Generic Frontend Server that could make it crash if a
2337 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2340 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2341 Must be issued before open, in order to be in effect.
2343 --- 2.0.9-6 2004/01/12 Debian/Windows
2345 Make the SRU server more picky WRT unknown params, etc.
2347 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2349 New YAZ client command, options, that sets Z39.50 options.
2351 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2352 options from a string of tokens (one token for each option bit).
2354 Update SRW diagnostic code messages.
2356 --- 2.0.9-5 2004/01/07 Debian/Windows
2358 Handle user defined stylesheet for SRW/SRU.
2360 --- 2.0.9-4 2004/01/06 Debian/Windows
2362 Fix bug in decoding of Content-Length.
2364 --- 2.0.9-3 2004/01/06 Debian/Windows
2366 Fix a bug with decoding of XML packed records.
2368 --- 2.0.9-2 2004/01/05 Debian only
2370 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2372 Fix bug in SRW/SRU diagnostics decoding.
2374 --- 2.0.9 2004/01/05
2376 Fixed bug in Generic Frontend Server which could drop records exceeding
2377 preferred message size. Reported and fixed by Irina Dijour.
2379 Fixed calculation of package size for structured records in Generic
2380 Frontend Server. Reported and fixed by Irina Dijour.
2382 Fixed namespace for SRW/SRU diagnostics.
2384 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2386 --- 2.0.8 2003/12/22
2388 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2389 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2392 CQL changes to reflect recent changes to the specification:
2393 * Documentation talks about context sets instead of index sets.
2394 * Documentation talks about indexes instead of qualifiers.
2395 * The CQL-to-PQF transformer's configuration file now uses
2396 "index.set.name = <attributes>" instead of the old form
2397 "qualifier.set.name = <attributes>". (Both forms are still
2398 understood but the latter is deprecated.)
2399 * CQL terms with no explicit index specified are now interpreted as
2400 cql.serverChoice instead of srw.serverChoice (which of course
2401 behaves exactly the same.)
2403 --- 2.0.7 2003/12/16
2405 MARC conversion can now generate ISO2709 output in another
2406 character set. yaz-marcdump uses this facility if you invoke it
2409 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2410 functions from there can be used from C++.
2412 --- 2.0.6 2003/12/04
2414 Frontend server now transfers memory from decoded packages to stream
2417 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2418 references to show up.
2420 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2421 the ZOOM Abstract API. The older names for the same options are still
2422 also supported for the benefit of old applications.
2424 ZOOM-C supports "implementationId" and "implementationVersion" options
2425 to go along with "implementationName". These allow the user code to
2426 specify identification strings to be sent to servers.
2427 Add OID for the new ExtLite attribute set.
2429 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2430 as requested/supplid by Ere Maijala <ere@atp.fi>
2432 For generic frontend server, reverse the order of
2433 "toolkit-supplied / application-supplied" strings sent as implementationId,
2434 Name and Version. Also, remove the spaces around the slash. This brings
2435 the GFS in line with the behaviour of ZOOM-C on the client side.
2437 Add function ZOOM_scanset_display_term.
2439 yaz-client shows scan displayTerm if present.
2441 Utility yaz-iconv is now installed by default along with the man page
2444 Extend configure check for OpenSSL to use pkg-config where available (such
2447 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2448 server to specify uid/gid/mask for socket using the format
2449 unix:[user=uid,][group=gid,][umask=mask,]file=path
2450 If file= is omitted the existing format is assumed, e.g.
2452 in which case the mask is 0666 (rw for everybody).
2454 Major restructure of YAZ source. All source in libyaz is in src directory.
2455 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2456 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2458 Added man page for utility yaz-marcdump (used to be called marcdump).
2459 yaz-marcdump is installed by 'make install'.
2461 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2462 of incoming package failed.
2464 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2466 Change prototype of odr_perror: add const to message string.
2468 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2470 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2471 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2472 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2473 DNS lookup. There should not be any compatibility problems with this
2474 assuming that blocking=1 or 0 is used.
2476 Fix bad reference in UNIX comstack in function cs_addrstr.
2478 Fix for compilation on AIX.
2480 The generic front-end server (server/seshigh.c) now supports returning
2481 Init diagnostics to the client in User-information-field, in
2482 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2485 --- 2.0.4 2003/09/04
2487 Allow any CQL relation (not just all,any,exact,scr).
2489 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2490 that features the same UI.
2492 Implemented command update0 in YAZ client which is equivalent to
2493 update but uses old of Ext Update ASN.1.
2495 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2496 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2497 Previously no OID was used for this info.
2499 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2500 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2501 returns 'malformed search term' otherwise.
2503 SortResponse member resultCount now set to NULL in sort handler of
2506 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2509 Add three new utility functions for translating OIDs between various
2510 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2511 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2512 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2513 char *oid_to_dotstring(const int *oid, char *oidbuf);
2514 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2516 Reverted modifications for ES Update definition for z_IU0Update
2517 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2518 is back to YAZ 2.0.2.
2520 String value attributes for CCL parser.
2522 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2523 which their FirstSearch server returns in Init responses, sometimes
2524 carrying useful diagnostic information when Init fails. This has the
2525 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2526 "z39.50/oclcui.asn", where its definition is somewhat different from
2527 what OCLC document on their web-site, as required to interoperate with
2530 Support for anonymous authentication in yaz-client. Use the command
2533 * Fix the OID of the Index Data-local "admin" Extended Service from
2534 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2535 the 1000, which indicates a locally-defined OID, was a mistake.
2537 --- 2.0.3 2003/06/20
2539 Fix CCL directive @case handling so that it affects string match for
2540 both CCL keywords and qualifiers.
2542 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2543 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2544 Decoder has been updated with ASN.1 changes as listed in
2545 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2546 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2547 z_IUUpdate, remains unchanged.
2549 ZOOM_record_get may now return a record in a specific character set.
2550 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2551 "from" is the character set of record as returned by target. "to" is
2552 the character set to be returned. If omitted, "to" is UTF-8.
2554 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2556 New ODR utility, odr_getelement, which returns name of element for
2557 which encoding/decoding failed.
2559 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2560 in cases where a required element was omitted.
2562 Bug fix: some MARC8 sequences were not converted.
2564 New ZOOM option "step" which specifies number of records to be
2565 retrieved in one chunk. Used in conjunction with "start" and "count".
2567 SRW support for yaz-client. Use scheme http: to use it, e.g.
2570 yaz-client no longer does (un)intelligent character set conversions
2571 by default. Can be enabled with charset and marc_charset commands.
2573 xmalloc trace fix for 64-bit systems such as DEC alpha.
2575 Solaris 2.6 compile fix.
2577 New function, cql_strerror() translates SRW error codes, as returned
2578 by cql_transform_error(), into human-readable English strings. Used
2579 in yaz-client diagnostics when appropriate.
2581 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2582 converts it into a type-1 query which is sent to the server. This
2583 makes CQL available for use with all Z-servers, as opposed to the tiny
2584 minority that can handle CQL queries themselves.
2586 --- 2.0.2 2003/04/28
2588 New Debian package layout similar to the Redhat Package layout.
2590 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2591 and search result respectively.
2593 --- 2.0.1 2003/04/25
2595 Redhat package is now several packages: libyaz (runtime libraries),
2596 libyaz-devel (development and documentation, and yaz (utility programs).
2597 Package spec file by Morten Bogeskov.
2599 New member 'schema' in struct bend_fetch_rr which the name of requested
2600 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2601 handler MAY set this to reflect the schema of the returned record.
2603 New member 'display_term' in struct scan_entry. GFS now sets member entries
2604 and allocates scan entries to be filled by user scan handler. In previous
2605 version, entries member was allocated by the scan handler. That still works,
2606 but the GFS will ignore member display_term - assuming it was NOT set by
2607 the handler. The fact that the GFS now allocates the entries both allows
2608 for new members and makes a scan handler easier to write.
2610 Fix CQL lex buffer overflow.
2612 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2613 SRU default recordPacking is string.
2615 SRU protocol support for frontend server.
2617 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2619 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2621 Added scan for the ZOOM shell (zoomsh).
2625 * String Identifers for Schemas (Amendment 5).
2626 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2627 Old definition for schema
2628 Odr_oid *schema; /* OPT */
2633 Z_InternationalString *uri;
2634 #define Z_Schema_oid 1
2635 #define Z_Schema_uri 2
2638 * resultCount parameter to Sort Response (Amendment 1).
2639 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2641 Support for SRW 1.0 over HTTP. This is an optional feature and
2642 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2645 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2646 on the same port. SRW SearchRetrieveRequests are mapped
2647 to bend_init,bend_search,bend_fetch,bend_close.
2649 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2651 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2652 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2654 ZOOM connections are SRW based if schem http is used for hostname
2655 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2656 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2658 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2659 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2660 distance=n, order=true/false, relation=le, prox unit=word. If
2661 n is omitted, distance 1 is used.
2663 Fixed problem with C compiler include path in wrong order.
2665 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2666 on Solaris. Patch from Ko van der Sloot.
2668 New MARC decode API. All new functions operate on a yaz_marc_t
2669 handle. The most important new functions are: yaz_marc_create,
2670 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2671 decode and destroy respectively. Decoder can produce formats
2672 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2673 include/yaz/marcdisp.h.
2675 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2676 to UTF-8, UCS-32, wchar_t or Latin-1.
2678 * Prototypes for yaz_iconv_-functions moved to separate header
2679 include/yaz/yaz-iconv.h.
2681 Make a few private functions 'static' in unix.c. This prevents
2682 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2684 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2685 are set when Init Response is received.
2687 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2688 but returns diagnostic set as well.
2690 New function yaz_strerror which is a portable wrapper for
2691 strerror/strerror_r/GetLastMessage.
2693 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2694 is returned for MARC. If type is "oai", then OAI MARC is returned.
2696 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2699 --- 1.9.2 2002/11/26
2701 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2703 Fix bad race conditions on SIGTERM and terminate gracefully in
2706 Move retrieval (data1) module to Zebra since nobody seems to be
2709 Add GRS-1 render for ZOOM using same format as yaz-client.
2711 --- 1.9.1 2002/10/05
2713 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2715 Fix broken ESpec handling in data1 module.
2717 SGML reader parses comments and makes them part of the data1 tree.
2719 Added several type casts so that YAZ compiles as C++ code.
2721 ZOOM didn't handle PDU encoding failures properly.
2723 Added more Bib-1 diagnostics (approved extensions).
2725 GNU configure: better check for iconv.
2727 More portable use of accept, getpeername. Check for socklen_t. Use
2728 int/size_t if socklen_t is not defined.
2732 PQF parser rejects bad queries - including those with extra
2733 characters in them. PQF parser used to silently ignore that.
2734 Cleaner API for PQF added, which allows you to get detailed
2735 error information for bad queries (see yaz/pquery.h).
2737 Fixed bug in ZOOM_record_get for type "database".
2739 Implemented mini iconv library supporting conversions between
2740 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2742 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2744 --- 1.8.9 2002/08/20
2746 Fixed ZOOM C record cache so that preferredRecordSyntax and
2747 elementSetName is used to check for already fetched records.
2749 --- 1.8.8 2002/08/02
2751 Added three members in bend_initrequest structure to facilitate
2752 character set negotiation.
2754 Fixed a bug in frontend server that could cause indefinite
2755 loops under rare conditions.
2757 Revised character set utilities (charneg.h) so that encoding
2758 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2760 For PQF, directive @term <type> sets term type for Scan/Search.
2761 Here <type> is general, string, numeric, null. The term type
2762 is inherited - just like @attr.
2764 New call odr_set_charset that sets character set conversion for
2765 international-strings on a ODR stream. Prototype is:
2766 int odr_set_charset(ODR o, const char *to, const char *from);
2767 The InternationalString is still represented as C string in YAZ
2768 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2769 won't). On the protocol level, you can use any encoding.
2771 Support for UNIX sockets in ZOOM.
2773 Solaris recv sometimes returns errno == ENOENT. It is treated as
2774 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2776 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2777 both client and server. Code by Morten Bogeskov.
2779 --- 1.8.7 2002/05/22
2781 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2782 that they can be used directly from Visual Basic. You must recompile
2783 your windows APP if you're using ZOOM.
2785 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2786 Commands "lang" and "charset" sets language and character set respectively.
2787 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2788 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2790 Attributes from multiple CCL fields may be OR'ed rather than merged
2791 using directive "@field or". Fields are still merged by default -
2792 equivalent to "@field merge".
2794 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2797 Fixed bug in zget for parameter ExtendedServicesResponse.
2801 --- 1.8.6 2002/03/25
2803 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2805 Client displays USR.1:SearchResult-1 (hits per term).
2807 Additional Search Info for search in Generic Frontend Server.
2809 Fixed CCL parsing of "field=s".
2811 WIN32 installer - using the excellent NSIS software from nullsoft.
2813 Fixed CCL parsing of "field = - <number>".
2815 Added function yaz_marc_decode that decodes MARC for line mode
2816 display or XML (similar to that used by JZKit).
2818 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2819 Z39.50. But ISO/ILL was, however.
2821 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2822 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2824 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2825 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2827 --- 1.8.5 2002/02/03
2829 New YAZ client features: Command completion and new commands:
2830 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2831 Code provided by Jacob Poulsen.
2833 New call oid_trav, that visits all registered OIDs via callback.
2835 Function ZOOM_record_get now returns const char pointer rather than
2836 void pointer. It saves a lot of type casts.
2838 For YAZ client, command "auth" now allows you to set authentication
2839 in IdPass style. It is enabled when three tokens are given - order
2840 is user, group and password.
2842 Fix memory leaks in MARC record handling for ZOOM.
2844 New option for YAZ client, -k <kilobytes> that sets
2845 maximum record size. Similar to -k option for generic frontend
2846 server and yaz-ztest.
2848 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2850 Prefix query parser reports "fail" when bad attribute set is given.
2852 Fix in MARC decoder. Proximity logging. Fix for attribute set
2853 in scan handler for server. Patches by Shigeru Ishida.
2855 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2858 Configure option --with-openssl=<dir> now works when a directory is
2859 specified. Patch provided by Morten Bogeskov.
2861 New option for YAZ client, -u <auth>, that sets authentication.
2863 ZOOM fix: error information was sometimes "missing", since error
2864 was cleared/reset too when it shouldn't.
2866 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2868 --- 1.8.4 2002/01/04
2870 Scan for ZOOM API. New object ZOOM_scanset. New functions
2871 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2872 ZOOM_scanset_destroy.
2874 New ZOOM function, ZOOM_connection_last_event, that returns type
2875 of last event (such as "receive data", "send data", "apdu received",
2878 New ZOOM option, schema, that specifies schema for retrieval.
2880 New CCL feature. Qualifiers can be aliases for one or more
2881 other qualifiers (if more than one is given, OR is used).
2883 ZOOM uses named result sets if target supports it.
2885 Two new YAZ client commands: . (dot, which sources a script of YAZ
2886 client commands), and ! (to execute shell command.). Implemented
2889 Working on Debian packages.
2891 --- 1.8.3 2001/11/19
2893 YAZ client enables named result sets only if target supports it.
2895 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2897 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2898 with key="host" to get same result.
2900 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2901 Function Z3950_resultset_record(s) returns references to records
2902 "owned" by resultset. To become owner use Z3950_record_clone.
2904 Function z_ext_record handles Extended Services. Thanks to
2907 --- 1.8.2 2001/11/12
2909 CCL Parser fix: ignore token comma when dealing with and-lists.
2911 Documentation updates for COMSTACK.
2913 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2914 Changed prototype Z3950_records. For some functions, int parameters
2915 were changed to size_t.
2917 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2920 New MARC decode/display function, marc_display_exl, which properly rejects
2921 non-ISO2709 records. YAZ client uses it.
2923 --- 1.8.1 2001/10/29
2925 Fix bug: local attribute set wasn't set correctly in PQF strings.
2929 * Old Z39.50 codecs no longer supported.
2931 Added ZOOM C binding. See http://zoom.z3950.org/
2933 Renamed states for COMSTACKs to avoid confusion with events.
2935 Implemented cs_look and proper cs_rcvconnect.
2937 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2939 Configure detects POSIX threads on OpenBSD.
2941 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2942 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2944 When error is returned from present handler, non-surrogate diagnostic
2945 is returned in present response (and fetch handler is no longer called).
2947 * Minor adjustments to pquery parser (PQF). Token characters may be
2948 escaped by using backslash (C-style).
2950 PQF parser allows string attribute values to be specified. For @attr,
2951 non-numeric characters after the equal-sign are treated as strings
2952 (e.g. @attr 9=title).
2954 CCL trunction character may be defined (@truncation in file)
2956 * function zget_ExtendedServicesRequest sets waitAction to
2957 waitIfPossible (was wait).
2959 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2962 CCL operator names may be set in field definition files (CCL_bibset).
2963 See ccl/bib1 for an example.
2965 Fixes in ASN.1 compiler for C++ compatibility.
2967 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2968 and "op_or" to avoid conflict with C++.
2970 Fixed problem with GNU readline detection on Redhat 7.0.
2972 Added step-size for Scan backend handler.
2974 Fixed bug that made the frontend server crash when no attribute
2975 set was specified for scan.
2977 Front-end server automatically switches to original working directory
2978 when installed as an NT service. Previously -w had to be specified to
2981 Added extended attributes for retrieval module (data1), so that data1
2982 records carry d1_readXML/SGML attributes. d1_read also supports
2983 null-data rules ( <tag/>)
2985 On UNIX when POSIX threads are available, a separate library libyazthread
2986 is created. Programmers should link with that library and the yaz library
2987 when using threads. The reason for the split was that some applications
2988 on Linux, such as Apache, doesn't work well when using shared objects that
2991 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2992 (or any frontend server) in SSL mode by specifying ssl: followed by
2993 address. Only tested on UNIX.
2995 Added feature for CCL module. Virtual structure s=al or s=ol generates
2996 and-list and or-list respectively instead of phrase search.
3000 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3001 log_mask_str. This was done to avoid name conflicts with other libraries
3002 (such as other PHP extensions).
3004 Added raw OID member for preferred record syntax (request_format_raw)
3005 and returned record syntax (output_format_raw) for backend fetch method.
3007 Config file yaz-config now accepts options so that it returns specific
3008 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3010 Shared library support for UNIX using GNU libtool.
3012 * Modified backend interface. Request/Response struct's replaced by
3013 one read/write C struct. For example bend_fetchrequest and
3014 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3015 Every handler - even search has to be registered in bend_init
3016 handler. This means that the YAZ library no longer refers to
3017 external functions and it makes it possible to make the whole
3018 thing a single DLL/SO.
3020 Added Segment handler for backend server.
3022 Added Zmbol/Zebra administrative functions to YAZ client.
3024 Threaded frontend server on UNIX (when POSIX Threads are available).
3025 Starting the server with option -T enables multi-threading.
3029 Added configure option --enable-comp/disable-comp to control use
3030 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3031 located in sub directory asn.
3033 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3034 in ${exec_prefix}/bin along with the other programs yaz-client and
3037 GNU automake used to maintain makefiles.
3039 Added several OID's.
3041 Changed retrieval module so that we can load records with no abstract
3042 syntax defined. Tagpaths in these records are fully composed of string
3045 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3049 On UNIX, the generated makefile now supports a proper 'make install'.
3050 The prefix can be set via GNU configure to set the install location
3051 (default is /usr/local).
3053 * YAZ programs client and ztest were renamed to yaz-client and
3054 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3055 locations, such as /usr/bin,/usr/local/bin,etc.
3057 * YAZ Header files were moved from include to include/yaz. YAZ Header
3058 files are referred to as include <yaz/log.h> rather than <log.h>.
3059 The YAZ include path (-I ..) is therefore the same as before. Programmers
3060 should update their #include statements or use -Ipath/include/yaz
3061 instead. The main motivation for doing this change is that YAZ header files
3062 can be installed in "standard" locations /usr/include,/usr/local/include
3063 without introducing conflicts, since ALL YAZ header files are stored
3064 in subdirectory yaz (under /usr/include for example).
3066 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3067 rather than project/workspace files. We switched because project files
3068 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3071 Changed name of logging function, logf, to yaz_log, to prevent name
3072 clash with some math-log functions. The YAZ header log.h defines logf
3073 to yaz_log (#define) so there should be no incompatibilities by this
3076 Added bend_start/bend_stop handlers for server. These handler are
3077 called on start/stop of server. For windows they are called whenever
3078 a service is started/stopped.
3080 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3081 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3082 in util/yc.tcl. The auto-generated C code structures are, in a few
3083 cases, incompatible with the old decoders. There are differences in the
3084 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3085 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3086 The preprocessor variable ASN_COMPILED is defined when the compiled
3087 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3088 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3089 wish to use the old encoders/decoders you can specify --disable-yc
3092 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3093 version so that it supports both new - and old version of DB Update
3095 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3096 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3097 change. The name parameter can be set to 0 in which no name is specified
3098 for the construction. The macros odr_implicit and odr_explicit sets name
3099 parameter to zero for the construction involved. New macros
3100 odr_implicit_tag and odr_explicit_tag are similar to the others,
3101 except that a name parameter is added. For programmers' that don't use
3102 ODR they probably only need to change the call to z_APDU and z_External.
3104 Added access control facility by interfacing the TCP wrapper library.
3105 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3106 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3107 name of the daemon and enables the access control as specified in
3108 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3110 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3111 den Dool <H.M.vdnDool@kub.nl>.
3113 Added reference ID parameter to most functions in server API - refer
3114 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3116 Changed name of ccl library to libccl.a (was ccl.a).
3118 Fixed bug in decoder for Explain (Category TargetInfo).
3120 Added support for GNU readline in client. Thanks to Jacob Poulsen
3121 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3123 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3124 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3125 IMPLEMENTATION! This change was made to the development version before
3126 the ZIG decided to retract the amendment. If any users MUST be
3127 compatible with the original Update definition, PLEASE CONTACT US, and
3128 we will include a separate definition corresponding to the old Update
3129 ES. Note that because of the change to the ASN.1 of the
3130 TaskPackageRecordStructure we cannot define a single structure that
3131 will support both versions.
3133 * Added const modifier to buffer parameter for some ODR/BER encoding
3134 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3135 completeWAIS, odr_dumpBER.
3137 Fixed bug in client.c which caused a crash when a scanResponse didn't
3138 contain positionOfTerm.
3140 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3141 * will cause an error in a client if a non-YAZ target sends both a
3142 * list of Scan entries and non-surrogate diagnostics.
3144 Retrieval module enhancements. Tag sets may be typed in the reference
3145 to it. From the .abs-file the "tagset" directive takes a third optional
3146 integer type for the tag set referenced. From a .tag-file the "include"
3147 directive takes a third optional type as well. The old "type" directive
3148 in the tag set itself is still recognized but acts as the default type
3151 Backend interface change. Individual Scan terms returned from bend_scan
3152 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3153 in include/backend.h.
3155 Retrieval module enhancements. Multiple tag sets and attribute sets may
3156 be specified in abstract syntax specs. Revised the error/warning for
3157 logging messages reported by the retrieval module when reading the
3160 Object Identifier system (oid_..) changed. The API is backwards
3161 compatible but the oid-routines now allocates new OID's when needed.
3162 Raw OID's may be specified in oid_getvalbyname.
3164 YAZ now uses GNU configure to generate Makefile(s).
3166 * Minor changes in some of the member names of DeleteResultSetRequest and
3167 DeleteResultSetResponse. See include/proto.h.
3169 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3170 and added member 'languages' in TargetInfo (which was missing).
3172 Changed the way attribute sets are handled in the retrieval
3173 module. These are now cached, just like the abstract syntaxes
3176 Changed YAZ so that it links with compiled ASN.1.
3178 Added Explain-schema definitions and mapping routines. The following
3179 Explain categories have been implemented: AttributeDetails,
3180 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3182 Fixed minor bug in Windows version of Server Library.
3184 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3186 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3188 Added EXTERNAL: UNIverse Resource Report (non-standard).
3190 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3191 ENUMERATED and SET OF.
3193 * Added 'const' to some of the char pointer arguments for the
3194 functions, data1_read_node, data1_getelementbytagname,
3195 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3198 Fixed bug in data1_insert_taggeddata - the last_child member of
3199 parent wasn't initialised.
3201 * Changed data1_read_record and data1_read_node so that the supplied
3202 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3203 doesn't refer to any parts of the "SGML"-buffer.
3205 Fixed bug in server library (Windows version of statserv_remove).
3207 * Changed code so that it compiles as C++. The type definition
3208 of Odr_fun which is a member of Odr_arm was changed. The result is,
3209 that an explicit typecast is needed for the fun pointer when
3210 using Odr_arm - as in:
3211 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3213 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3215 Implemented the new structured date and time definition as approved
3216 by the ZIG. Added schemaId element to the specificTag in Espec-1
3217 (also approved at the last ZIG). Thanks to RVDM.
3219 Added some Object identifiers (RVDM).
3221 Changed the Update Extended Service (RVDM).
3223 Added command "refid" to client which specifies referenceId for
3224 the following requests.
3226 Implemented extended service handling for server. See ztest.c
3227 for an example as well as backend.h. New handlers are registerd
3228 in the Init handler.
3230 * Changed interface for sort in server.
3232 Added new members to statserv_options_block. It allows a server
3233 to read options from another source than just the command line. Thanks
3234 to Charles Woodfield.
3236 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3237 renamed to zboolean. Some C++ compilers complained about the name.
3239 Minor changes to gils.abs. Added index 's' (sort) on title
3240 and date/time-last-modified.
3242 --- 1.4pl2 1998/1/30
3244 Fixed bug in server library regarding inetd mode (-i). This bug
3245 was introduced by release 1.4.
3247 --- 1.4pl1 1998/1/29
3249 Added sort facility in client and backend server interface.
3251 Fixed problem with dependencies in Makefile(s).
3253 Fixed bugs for encoders/decoders of extended services and
3256 Implemented sub-tree feature for schemas. Sub-trees are
3257 referenced in *.abs-files. See explain.abs for an example
3258 of the use of this feature.
3260 Modified bib1.att; local attributes for ANY didn't include
3261 ANY itself (only affects use of the retrieval module).
3263 Fixed bug in plain SGML reader in function data1_read_node:
3264 tags with prefix "var" was incorrectly interpreted as variants.
3266 Added feature "sub-schemas" to enable references to - and definitions
3267 of - group of elements.
3269 * Removed member parent from type data1_element (in data1.h).
3271 Implemented function odr_nullval() that returns the value of
3274 * Removed member num_children from data1_node (in data1.h).
3276 Made NT service interface part of the server library. The
3277 function statserv_main uses the NT service when required and
3278 calls the statserv_start / statserv_close routines.
3280 Routine zget_SearchRequest and zget_PresentRequest fills
3281 resultSetName/Id member with "default" instead of "Default".
3283 Fixed memory leak in server. Request queue member wasn't freed.
3285 Fixed nmem_exit so that memory is freed.
3289 Revised the CCL parser utility to be thread safe.
3291 Added function, oid_ent_to_oid, to replace the function
3292 oid_getoidbyent, which is not thread safe.
3294 * Added nmem_init and nmem_exit to initialize and release
3295 NMEM resources. Function nmem_init should be called once in the
3296 initial thread before NMEM/ODR is used. statserv.c and client.c
3297 have been changed accordingly. The change was necessary to make
3298 NMEM thread safe. The NMEM memory pool is shared amongst threads
3299 in a process. Unix-based applications will still work fine without
3302 Added NT Services interface for the the Z39.50 (statserv) Server.
3303 Refer to the ztest.c source on the usage.
3305 Windows 95/NT port using MSVC5.0. Project files are included in the
3308 * Defined new 'global' handle for the retrieval (data1) system. The
3309 new handled, data1_handle, describes the state of the data1 system.
3310 This handle is passed as first argument to virtually all
3311 data1 related routines. The functions data1_create and data1_destroy
3312 creates and destroys a data1 handle respectively.
3314 Added ODR encode stream member to all backend request structures
3315 init, search, scan etc. This stream should be used to allocate all
3316 memory used for the response when thread safe operation is needed.
3318 Changed the comstack utility, cs_addstr, to be thread safe. The
3319 returned hostname string returned by the function is now part the
3322 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3323 function. The cs_straddr takes a COMSTACK handle as argument, so this
3324 function must be used after cs_create and before bind/connect.
3325 This function is thread safe.
3327 Moved test server to 'ztest' directory - generic server code still
3328 in 'server' directory.
3330 Made prefix query (pquery.c) utility thread safe.
3332 Added new function modifier YAZ_EXPORT to 'export' public DLL
3333 functions when using windows (see include/yconfig.h).
3335 Added definitions to the OID database (util/oid.c) (RVDM).
3337 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3339 Added call to ccl_rpn_delete in client program.
3341 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3342 release of RPN structure.
3344 Added support for C++, headers uses extern "C" for public definitions.
3345 With input from RVDM.
3347 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3348 Thanks to Ronald van der Meer (RVDM).
3350 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3352 Added support for private extensions to the OID database
3353 (oid_setprivateoids()). Thanks to RVDM.
3355 Added optional, physical ANY (key replication)
3357 Fixed null-reference problem in GRS-1 output filter.
3359 Proximity operator added to Prefix Query Format (PQF).
3361 In test client command "base" accepts multiple databases.
3363 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3367 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3369 Smallish bug-fixes in the new encoders/decoders (explain).
3371 Bug fixed in DeleteRequest.
3373 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3375 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3377 Added SOIF syntax (using private OID for now) to retrieval module and client.
3379 Added Update extended service.
3381 Added SearchResult-1 additional info structure.
3383 Added optional CCL (ISO8777) interpreter as separate module. Available
3386 --- 1.2 1996/6/10 (1st anniversary release)
3388 Added Summary record syntax. Lightly tested.
3390 Added OPAC record syntax. Untested.
3392 Added ResourceReport service encoders/decoders. Untested.
3394 Fixed bug in z_Unit - wrong tagging on unitSystem.
3396 Fixed bug in the DiagRecs decoder.
3398 Added options for max PDU size and session timeout to frontend-server.
3400 Added documentation of query-language parsers and other supporting utilities.
3402 [frontend-server] Added Attribute set to the bend_scanrequest API.
3404 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3405 surrogate diagnostics were generated.
3407 [retrieval] Allow multiple local values for attribute.
3409 [retrieval] Allow multiple attributes per element in .abs files. index type.
3411 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3413 --- 1.1pl2 1996/4/10
3415 Minor changes, mostly specific to Zebra's requirements (retrieval)
3419 Repaired bug in frontend server when running multiple listening
3420 endpoints in dynamic mode.
3422 z_External() now won't break if a known, ASN.1 value comes encapsulated
3423 in an octet-string. The value will pass through unmodified in an Odr_oct.
3425 Added a bit of code to the demo client to decode & display
3426 ASN.1-structured records represented in the octet-aligned branch of
3427 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3429 Added z_ext_getentbyref() to the ASN module. Doc updated.
3431 * Completed the SCAN definition in the ASN module. This may break SCAN
3432 code based on older YAZ-versions at compile-time. The fix is easy -
3435 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3436 under the SCAN definition. Remember to initialize this, server-people.
3438 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3439 that this does not extend to ODR and ASN.
3441 Comstack allows insertion of established socket (primarily for
3442 inetd-operation of servers). Doc updated.
3444 Front-end server can now start from the inetd in TCP mode. Doc
3447 --- 1.0pl4 1996/1/24
3451 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3452 the rank and record number.
3454 Adjustments to the frontend server.
3456 Fixed diagnostic BER dumper. It ignored the file argument.
3460 Various changes to retrieval module.
3462 Changed the union discriminators of the protocol files from enums to
3463 ints paired with #defines.
3465 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3468 *Changed operator in the RPN structure to 'roperator', again to avoid a
3471 Fixed problems in Explain decoders/encoders.
3473 --- 1.0pl2 1995/12/6
3475 Memory bug in log module fixed.
3477 --- 1.0pl1 1995/12/5
3479 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3481 Bug in Explain DatabaseInfo module fixed.
3483 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3487 The shift to v1.0 signals that we now consider the *core* functionality
3488 of YAZ reasonably stable (the core being more or less equivalent to
3489 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3490 tested (Explain not at all - though that will happen soonish).
3492 Minor changes to code to support Windows port.
3494 Various minor changes after we're getting to use GRS-1 & co. more.
3496 Added Espec-1 format.
3498 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3499 of the protocol and it cannot be selected when encoding (maps into 'string'
3500 when decoding). Needed to talk to some servers.
3502 Demo client can request simple element set names.
3504 Added Diagnostic Format encoders/decoders.
3506 Added simple Close handling to frontend server (no hooks for resource
3507 reporting yet), and demonstration client.
3509 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3511 --- 1.0b3 1995/08/24
3513 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3514 handled incorrectly when records were requested in the searchResponse. This
3515 will only affect you if you use the frontend-server.
3517 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3518 Test-client will ask for and print GRS1. Ztest will return dummy records
3521 Added Explain encoders/decoders to the service-level API. Untested.
3523 Added Extended Services: Item Order encoders and decoders to the Service-
3524 level API. Untested. We could use a recent copy of the pertinent bits
3525 of the ILL protocol to add those bits.
3527 Added diagnostic format 1 encoders/decoders to the service-level API.
3530 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3531 odr_cons.c, which causes a more correct output.
3533 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3534 was always set to 0 when no records were requested in the searchRequest.
3536 * Added better external-handling. This shouldn't harm old code that
3537 *encodes* externals. It can break code that looks for a
3538 'single-ASN1-type' representation, since those types that are known
3539 are now decoded immediately. Look at the SUTRS sample code in
3540 seshigh.c and client.c. Documentation updated.
3542 Handling of structured records in bend_fetchresponse. Length -1 marks
3543 structured record, type is deduced from format field.
3545 --- 1.0b2 1995/06/27
3546 Fairly quick maintenance release to add SUTRS support.
3548 Fixed handling of SUTRS records in the demonstration client.
3550 * Added format field to the bend_fetchrequest and bend_fetchresponce
3551 structures of the backend API (frontend server). When the record is
3552 returned, the value of the format field is mapped to an OID. The
3553 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3554 of the record. The special value VAL_NONE in the bend_request means
3555 that no specific format was requested by the client. Documentation
3556 updated accordingly. Test server (ztest) will return a fixed dummy
3557 SUTRS record if your client requests SUTRS.
3559 Documentation updated accordingly.
3561 You can now set external libraries and RANLIB support in the top-level
3565 First public release.
