3 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
4 schema was given for search. YAZ-675
6 Add Solr date range searches. YAZ-621
10 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
12 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
14 ISO2709/MARC parse most octet aligned records; not just those that
15 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
16 MARC parse more records instead of just dumping as is. YAZ-670
18 ZOOM: proper caching for variations of record schema. YAZ-671
20 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
28 New utility z_get_HTTP_Response_details - an extended version of
31 New utility yaz_url_get_error which returns error message of last
32 failed yaz_url_exec call.
34 yaz-url and url functions: allow max HTTP redirects to be controlled.
36 New functions yaz_file_glob2, yaz_xml_include_glob.
37 These functions takes a flags parameter, which, for now only controls
38 whether to fail inclusion of a non-existing file (without glob
39 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
43 For MARC XML parsing, allow record without leader. A fake/default leader
44 is inserted and a warning is tagged with the record.
46 ICU: fix leak in in icu_iter_get_org_info.
50 ICU: fix bug in icu_iter_get_org_info (un-init variable).
54 Implement z_HTTP_header_remove.
58 ICU: Disallow 0 ptrs for some ICU string utilities.
60 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
61 returns original tokens (before normalization).
63 CCL: avoid z39.58/regex truncation when not needed. Apply only the
64 conversion of those masks, when absolutely necessary.
66 CCL: configurable masking character - @mask. Default masking character
69 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
70 full response anyway, so a Transfer-Encoding header will obstruct the
75 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
76 picking a socket. Problem is that some systems has IPV6 support, but
77 we can't create sockets for them, so we pick AF_UNSPEC first.
79 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
80 use content_len to determine resulting Content-Length in HTTP response
81 and NOT Content-Length supplied in headers by user.
83 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
84 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
86 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
89 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
90 with big endian and unsigned char (by default).
94 Fix yaz-client connect (crash in 4.2.55).
98 Fix proxy/host problem for ZOOM that could occur if unix sockets
101 New Debian package libyaz4-dbg.
103 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
104 differently in tcpip_close.
106 --- 4.2.54 2013/04/17
108 Windows installer of YAZ includes YAZ4J as a component.
110 CQL: allow "extra terms" again, by default. Thus, the CQL parser
111 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
112 and earlier. CQL parser may operate in strict mode where queries
113 not conforming to the standard BNF are rejected (syntax error).
114 Whether the CQL parser operates in strict mode is controlled with
115 cql_parser_strict . Strict mode enabled with option -S for utilities
116 cql2pqf and cql2xcql .
118 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
120 --- 4.2.53 2013/04/10
122 New charset, MARC-8c, which is like MARC-8 but allows control characters
123 0x01 through 0x1F, except ESC to be passed through verbatim.
125 Fix a problem with duplicate sub field character in MARC output. Problem
126 happened only when output was MARC-8 encoded.
128 --- 4.2.52 2013/04/03
130 yaz-ztest: Use hash for fake hit count. Before, random number was used.
131 This is problematic for unit tests using yaz-ztest. This patch also makes
132 a hash for CQL queries. For RPN, any term with a leading digit will be
133 treated as pseudu hit count (to force any particular hit count by a client).
135 yaz-ztest: return unique MARC dummy records. Beyond record offset
136 24, the author surname is patched with offset to make all records
139 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
140 on system wide default (/proc/sys/net/ipv6/bindv6only).
141 @4 binds to IPV4 only. @6 binds to IPV6 only.
143 Update CQL API documentation a bit
145 CQL: don't accept extra terms for queries. Makes the CQL parser
146 stricly conformant to the standard.
148 --- 4.2.51 2013/02/12
150 GFS: scan handler gets extra_args from request and may return extra
151 response data . That's for SRU only.
153 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
155 --- 4.2.50 2013/01/30
157 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
159 OPACXML: sync spelling of availabilityDate in XML to that of Schema
160 opaxxml.xsd. The schema had the correct spelling of this member always.
161 The ASN.1 was mis-spelled and still is (API change) - we are
162 not changing this. However, the OPAC to XML conversion had yet
165 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
168 New function, z_ext_record_oid_nmem, which is similar to
169 z_ext_record_oid but takes NMEM rather than ODR
171 --- 4.2.49 2013/01/18
173 ICU: New conversion element 'join' which joins tokens into one
174 with a custom character given by rule attribute.
176 --- 4.2.48 2013/01/10
178 New GFS search member: present_number. This is a hint to the
179 search handler how many records are going to be fetched immediately
180 following search. There's no guarantee that it's going to be the case,
181 since it depends on hit count (for Z39.50 piggyback) and whether errors
184 Make a few functions static (private). The functions getbyte_stream,
185 ungetbyte_stream and yaz_gets are now private. They were never declared
188 yaz-marcdump: exit(5) for serious decoding errors
190 ISO2709 decoding: be more picky WRT header
192 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
193 was only used as to indicate that next-result-set-position should be
195 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
196 Based on patch from Ashley Sanders.
198 Make some functions static/private in PQF parsing. Those functions were
199 never declared in a public header and so should not be in use by
200 applications based on YAZ.
202 --- 4.2.47 2012/11/23
204 ZOOM: special options to control APDU logging.
205 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
206 logging of APDUs until "saveAPDU" option is set again. If logging is
207 already enabled the effect is that current APDU buffer is cleared.
208 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
209 logging (default behavior on new connection).
210 The APDUs sent/received can be obtained by using
211 Using ZOOM_connection_option_get(c, "APDU") or
212 ZOOM_connection_option_getl(c, "APDU", &l).
214 GFS: relay implementation_version from backend
215 From 3.0.40 and later, implementation_version from backend was
216 not used in init response at all.
218 --- 4.2.46 2012/11/15
220 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
221 mode at all. Probably never did.
223 Make a new version of ztest.pem that, at least, is not expired.
225 --- 4.2.45 2012/11/13
227 Fix description of CCL directive 'case'.
229 More tight checking of form arguments (yaz_uri_to_array). Makes
230 YAZ better at rejecting big and/or bad POSTs.
232 SRU decoding does not report more than up to 10 invalid arguments.
234 rpn2cql: less quotes in generated terms. Semantics unchanged, but
235 it's prettier this way.
237 --- 4.2.44 2012/10/25
239 New utility yaz_decode_init_diag. Defined in proto.h.
241 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
242 given for unix local socket.
243 The COMSTACK string for doing so is:
246 unix:/myfile:tcp:localhost:9999/mybase
247 unix:/myfile:localhost:9999/mybase
248 unix:/myfile:http://fakehost/mybase
250 debian: Use dpkg-buildflags in build process.
252 --- 4.2.43 2012/10/19
254 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
255 global's SRU service uses a recordPosition scheme starting from zero.
256 First record's position should be one
257 according to the standard.
259 --- 4.2.42 2012/10/18
261 Allow more namespaces for SRU. This is to allow, for example, an
262 incorrect namespace returned from server
263 http://services.igi-global.com/sru .
265 Minor fixes for compilation on Windows.
267 --- 4.2.41 2012/10/11
269 daemon: log total number of bad signals from child on stop so that it
270 is more easy to spot problems with child worker processes.
272 retrieval: empty backend name attribute omits element set
273 from being used in retrieval.
275 --- 4.2.40 2012/10/04
277 Implement Solr sort strategy "solr", similar to sru11 sorting.
278 This will implement the correct parameters on Solr requst to do
281 --- 4.2.39 2012/09/28
283 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
286 MARC: Extra/missing indicator handled for MARCXML.
287 The indicator length is given in header and is the same for the
288 whole record. If attributes ind1, ind2 are missing, then content
289 character defaults to blank. Extra indicator attributes (beyond)
290 indicator length are treated as an error.
292 Reformat: delete trailing whitespace
294 --- 4.2.38 2012/09/17
296 MARC: fix non-ASCII characters for leader. This is to ensure we can
297 generate XML in UTF-8.
299 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
300 in one node with structure word.
302 --- 4.2.37 2012/09/04
304 yaz-json-parse: JSON output may be pretty printed by using option
307 Increase default value of max message for Z39.50 Init for GFS, ZOOM
308 and yaz-client. Old value was 1 MB. New value is 64 MB.
310 --- 4.2.36 2012/08/22
312 yaz-client: don't display bogus records from SRU servers. Some SRU servers
313 return more records than given by *maximumRecords*. Skipping those in
316 record_render: simplify buffer return handling and fix at least one bad
317 memory reference, that broke the test_embed_record sometimes.
319 Allow http://user:pass@host notation for yaz_url_exec.
321 zoomsh: allow shell command to be executed. Via the system(3) call.
323 yaz_poll: Allow num_fds == 0
325 yaz-client: fix bad encoding of "itemorder item". The itemorder
326 item <no> - command forgot to use length of encoded Item Request
327 package. Error present since YAZ 3.
329 yaz-ztest: fix bad usage of session handle. Bug was introduced when
330 result sets were saved (271a9c83).
332 SRU recordPacking: guess record packing in response rather than looking
333 at the recordPacking element which, OF COURSE, changed semantics in SRU
336 Decode SRU 2.0 responses. The official namespace for responses, according
337 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
338 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
339 nature.com's server, however, usee namespace
340 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
341 we are now using a glob-expr to match up the namespace. ZOOM C and
342 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
343 I can not find a single real example showing the "real" namespace in
344 the documentation from OASIS. The namespace for requests is different
345 from responses, but this is not added to YAZ yet, when we don't encode
348 --- 4.2.35 2012/06/26
350 zoom/record_render: add support for Base64 decoding fo MARC records
351 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
352 which will decode base64 + ISO2709 marc-8 encoded material from text node
355 --- 4.2.34 2012/06/07
357 Add missing definitions ZOOM_resultset_get_facet_field_by_index
358 and ZOOM_resultset_facets_names.
360 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
363 Change APDU dump printing to avoid long leading blanks. For levels 16
364 or larger the level is shown and the indentation is truncated but
365 recursed with modula 8. This makes it still reasonable easy to read
366 - even for nested BER dumps.
368 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
369 return 0 (incomplete package) in case where the BER package was
370 considered too nested (return value of -2).
372 dumpber: lines of level 15 are not indented further. Two spaces per
373 indentation; indentation 15 or more is indented to a fixed indentation
374 and augmented with a level=<no> indication.
376 zoomsh: increase max size of command+args
378 GFS: No limit in RPN buf size in CQL to RPN conversion.
380 --- 4.2.33 2012/05/09
382 New function for daemon utility, yaz_daemon_stop .
384 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
386 --- 4.2.32 2012/04/25
388 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
389 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
391 --- 4.2.31 2012/04/23
393 YAZ daemon utility relays SIGUSR1 to child process.
395 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
396 would result in en empty database list - which in turn would result in
397 encoding failure for search.
399 Fix reading beyond string in yaz_sort_spec.
401 --- 4.2.30 2012/04/11
403 Add two new SRU diagnostics:
404 236: Access to specified database denied
405 1015: Init/AC: Maximum number of simultaneous sessions for Userid
407 Document the very useful ZOOM-C option "apdulog".
409 CQL to RPN: term may be passed through verbatim. This is enabled with
410 truncation.cql . The assumption being that the term is already CQL.
412 --- 4.2.29 2012/03/20
414 record_conv: leader spec may be given for marc element.
415 The leader spec is given as attribute leaderspec for element marc.
416 For example to convert a MARC21 record from MARC-8 to UTF-8:
417 <marc inputformat="marc" outputformat="marc"
418 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
420 record_conv: allow user-XSLT params. For example:
421 <xslt stylesheet="MARC21slim2DC.xsl">
422 <param name="myparameter" value="myvalue"/>
423 <param name="otherparameter" value="othervalue"/>
426 record_conv: fix error handling for missing marc charsets.
428 CQL: fix extra terms in wrong order.
430 --- 4.2.28 2012/03/06
432 record_conv: modify new API for conversion types. The conversion types
433 may be passed in new functions yaz_record_conv_configure_t and
434 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
436 Avoid mixed statement/variable declare; fixes compilation with Visual
439 --- 4.2.27 2012/02/28
441 Add non-standard SRU diagnostic: 235: "Database does not exist".
442 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
443 Update SRU to Bib-1 diagnostic maps accordingly.
445 CCL: add two new diagnostics for unsupported masking. The new
446 diagnostics are: "Embedded truncation not supported" and
447 "Single charcacter mask not supported".
449 --- 4.2.26 2012/02/23
451 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
453 --- 4.2.25 2012/01/11
455 Build YAZ for Ubuntu Oneiric.
457 CCL: allow parantheses for proximity operands. For example CCL query
458 (a) % (b) is now allowed.
460 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
461 marked dead, rather then being destroyed. If not, the session memory is
462 being free'd before the search/scan handler is finished. Also destroy
463 'request' memory in request_release rather than in various places,
464 which resulted in leaks from time to time.
466 --- 4.2.24 2011/12/21
468 cql_sortby_to_sortkeys: honor sort prefix.
470 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
471 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
472 The rpn2cql family of functions now always returns quoted CQL terms.
474 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
476 --- 4.2.23 2011/12/15
478 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
479 sequence is treated as one. For example, &&a=b&&&c& is identical to
482 --- 4.2.22 2011/12/05
484 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
485 APDUs for a connection to a WRBUF.
487 --- 4.2.21 2011/11/23
489 Fix cql_sortby_to_sortkeys. Completely broken before.
491 Make CCL's @truncation work again.
493 --- 4.2.20 2011/11/09
495 New ZOOM connection setting: tproxy. It's like proxy, but does not
496 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
497 to set resolved address + port for a connection outside ZOOM itself.
499 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
501 --- 4.2.19 2011/11/07
503 Fix uninitialized variable in Solr spell support (could cause SEGV
504 for SRU response decoding).
506 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
507 back-end's addinfo through into the ZOOM response addinfo.
509 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
510 they are separated by a colon and a space rather than simply
513 --- 4.2.18 2011/10/28
515 Add support for Solr spell-checking/suggestions through ZOOM.
516 If a Solr target has been configured correctly for spelling-checking
517 and suggestions, these will now be returned on the ResultSet option
518 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
520 --- 4.2.17 2011/09/28
522 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
523 with a flag whether to substitute escape sequences or not.
525 --- 4.2.16 2011/09/22
527 Fix nmem_strsplit_escape to substitute escape char properly.
529 New option for zoomsh -e , which makes it abort on first error and
530 return process exit code to indicate success/failure.
532 YAZ options utility supports special option -- which makes all it treat
533 all following arguments as non-options.
535 --- 4.2.15 2011/09/16
537 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
538 searched if absolute filename is given.
540 Fix conv_xslt() error-reporting when stylesheet is not found.
541 (The value of fullpath is meaningless in this situation.)
543 --- 4.2.14 2011/09/07
545 Fix problem in CQL sort node creation: un-initialized memory.
547 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
548 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
549 CQL sortby depending on whether Type-1 or CQL is actually sent to the
552 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
553 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
555 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
556 will make it possible to use both single-character mask (#) and wildcard (?)
557 in CCL . Throw diagnostic for left truncation because that is not supported
560 --- 4.2.13 2011/09/01
562 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
563 cases using escapes (\-sequences) and masking.
565 PQF parse fix: A trailing backslash followed by end-of-string (\0)
566 would result in a read one byte beyond string.
568 rpn2ccl may use Z39.50 masking for terms (t=z).
570 ICU check fix. Don't include library -lCrun on Solaris, unless present.
572 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
573 not --cppflags (which seeems like an error in icu-config).
575 --- 4.2.12 2011/08/27 RPM package only
577 cql2ccl: fix conversion of terms: operator characters were not
580 --- 4.2.11 2011/08/25 RPM package only
582 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
583 CCL parser will map both # and ? to their regular expression
584 quivalents (. and .*).
586 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
587 of reserved CQL characters.
589 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
590 is, so that they are passed through.
592 --- 4.2.10 2011/08/24
594 ZOOM SRU mode: more aggressive re-connect.
596 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
597 made available as a utility function, declared in <yaz/logrpn.h>
599 rpn2cql_structure() supports proximity nodes (except that the Type-1
600 proximity node's "exclusion" binary is ignored, as there is no way to
601 express that in CQL). Fixes bug #4564.
605 Fix SEGV that could occur if set command of zoomsh was given without
606 value (2nd argument).
608 Fix SEGV that could occur if unsupported transport was given for
609 COMSTACK - say https (when SSL was unavailable).
611 Build yaz-url on Windows too.
615 New utility to get web content. Header is url.h. A command line tool
616 yaz-url is part of the distribution and packages.
618 Fixes for SSL COMSTACK (when gnutls is in use).
620 New functions yaz_base64{encode,decode}. Header is base64.h.
624 ZOOM C includes HTTP response buffer as additional info if it fails
625 to decode the SRU response.
627 Make wrbuf_json_puts available.
631 zoom: throw diagnostic for invalid value for option "sru". Before a
632 bad SRU request was sent.
634 Adding new utility wrbuf_vp_puts.
636 Add cclxmlconfig.obj to win/makefile. It was missing completely.
640 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
641 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
642 redirect was used at the same time.
644 MARC line mode decoding: be less picky about length given - first
645 5 digits of header that is.
647 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
649 Changes to decoding of SRU records: a record with recordPacking=xml is
650 modified with a new root element <yaz_record> if the recordData contains
651 multiple children elements. This is to make the record XML parseable
654 RPN to Solr conversion: encode special characters.
656 Generic Frontend Server: fix uinitialized member, stepSize.
660 Fix a bug in SRU decoding of records.. The database records stored
661 had un-initialized memory, but it would only be seen with yaz_record_render
662 and type_spec="ext" .
664 Fix a bug in ccl_qual_dup introduced in 4.2.3.
668 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
672 Add new utilities to convert from CQL to CCL . These utilities have
673 prefix cql_to_ccl defined in cql.h.
675 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
676 lead to memory heap corruptions when ICU utilities were in use.
680 Make compilation work without Libxml2.
682 yaz-client: remove redundant blanks in display of searchResult-1 term
687 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
688 resulting CQL node (tree) in a new node CQL_NODE_SORT.
690 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
691 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
692 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
693 Note that the CQL sortby spec is only converted when the GFS is already
694 converting from CQL to RPN (cql2rpn element).
696 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
697 specify whether to collapse delimitors or not. The existing nmem_strsplit
698 do collapse (collapse parameter = 1).
700 Windows installer: For NSIS, set InstallDir depending on x86/x64.
702 Rename internal func yaz_use_attribute_create. While non-static, this
703 function is not declared in a public header.
707 Add -lCrun when linking with ICU on Solaris.
709 More quicks character set conversions for OPAC records.
713 fix problem with record_render: records were converted (character set
714 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
718 SRU: add methods for handling DADS SRU-proxy facets.
720 Separate OPAC record character set for ZOOM_record. yaz_record_render
721 allows a character set given as charset=from/opacfrom,to where 'from' is
722 the character set of a bibliographic record, 'opacfrom' is character set
723 of OPAC record and 'to' is the target character set.
727 yaz-client: show may XML format records. Command show followed by 'format'
728 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
731 src/stemmer.c: Avoid using unnamed union. It is not supported by some
734 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
737 Update yaz.spec to operate on both SLES11 / Centos 5.5.
739 RPM: Release includes 'indexdata' name. Use indexdata in release name so
740 this package can be distinguished from other vendors.
742 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
743 as determined by configure
745 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
747 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
748 returns no error and no record, the present request is considered
749 partial (only a subset of the records could be returned by backend), and
750 so it is appropriate to set Present Status to partial-4.
754 Move yaz-config man pages to section 1.
756 More documentation about Solr.
758 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
759 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
760 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
761 peers on some Linux systems. However, in general that does not work
762 so YAZ can not rely on that to work. Debian changed behavior in this
763 respect from Debian lenny to Debian squeeze (still testing as of Oct
765 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
767 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
771 Fix yaz-config output: echo_source not set correctly by configure.
775 Solr Web Service support for yaz-client and ZOOM.
777 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
779 --- 4.0.12 2010/08/17
781 Z39.50 facet support. Facet specifications are passed for search in
782 other-information with ASN.1 as defined in facet.asn and OID
783 .10.1000.81.5 . Facets are expressed as an Attribute list as known
784 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
785 3 is limit (number of entries to get in response). yaz-ztest returns
786 dummy facets if a client asks for them.
788 --- 4.0.11 2010/07/09
790 CCL fixes: bug 2895 and bug 3539.
792 GR1-display: add comma in display - was removed by mistake in
795 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
797 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
799 --- 4.0.10 2010/06/18
801 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
802 result set from a connection. The result set will be on its own
803 thereafter; no operations on it will perform retrievals from a target.
804 Only cached copies are returned.
806 ZOOM C:fix case for HTTP servers responding with Connection:close.
807 Ensure that if there is a current task it is resumed (like fetching
808 more records in a result set) . Bug #3484.
810 PQF parser: use odr_atoi for Odr_int (not atoi)
812 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
813 values that contain any non-digits are treated as string attributes
814 (previously decoding only checked for leading character ([0-9]). PQF
815 encoding: attribute string values are not surrounded by double-quotes.
819 New utility for managing threads - thread_create.h.
821 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
822 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
823 but YAZ' implementation do.
825 Fixes for yaz_cond-functions on Windows 7.
827 DLL export more symbols.
829 zoomsh: show record do NOT render opac.
831 Remove *.la files from Debian and RPM packages.
835 Debian package libyaz-dev depends on libgnutls-dev again (was
836 removed in YAZ 4.0.6, but due to Libtool it is still needed
837 even though yaz-config do not list libgnutls libs).
839 ZOOM: Use only one WRBUF for returning string results for
840 ZOOM_resultset. Reduces memory usage for ZOOM in general.
842 ZOOM: ZOOM_connection do not use a shared pointer to
843 ZOOM_resultset after ZOOM_resultset is destructed by
844 user. Reverts to YAZ 4.0.4 behavior.
848 record-conv: fix problem with at least one XSL conversion -
849 due to probably incorrect usage of XML XSL documents.
853 Fix yaz-config for static mode and the use of SSL (gnutls).
857 Forward decl timeval struct in mutex.h and gettimeofday.h.
859 yaz-config: fix 'static' mode linking.
863 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
864 are wrappers for pthreads or Windows. For Windows these are put in
865 a separate DLL: yaz_cond4.
867 libyaz.la (whole source) is compiled with thread. If thread support
868 is enabled enabled, all source of YAZ is compiled with treading support.
869 This allows core utilities such as yaz_log to use thread facilities.
870 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
871 thread utilities. This commit moves mutex utilities (mutex.c) from
872 libyaz_server.la to libyaz.la.
874 yaz-json-parse displays leading text until error.
878 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
879 patch from Giannis Kosmas.
881 SRU: no longer URL encode SRU database. The URL for an SRU server is
882 a URL and such is alreeady encoded - at least when given with leading
883 http:// or https://. This reverts behavior to YAZ 3.0.50.
885 Support for new MARC XML notation TurboMARC which like MARCXML is a
886 complete representation of MARC/ISO2709.. This one, however, is more
887 compact and allows for faster processing with XSLT. TurboMARC can be
888 used in the marcdisp.h API, from the yaz-marcdump utility and from
891 yaz-ztest can be configured - via the database - to perform certain
892 delays when it performs operations search, present and single record
893 fetch. This allows testers to make yaz-ztest act as a real or even slow
894 Z39.50 server. Refer to the yaz-ztest man pages for details.
898 wrbuf_destroy allows NULL WRBUF passed to it.
900 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
902 Add ZOOM_connection_close.
904 No fixed size buffers for ZOOM shell - bug #3257.
906 tstodr: make it work on s390 platform.
908 New icu iterator-functions. The new icu_iter-functions makes it possible
909 to use ICU chains from many threads.
911 yaz-client: better syntax check for show command.
915 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
918 New simple local-file XML include facility which allows file glob-patterns.
919 Refer to yaz/xml_include.h.
921 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
924 ZOOM_record_get supports new parameter "format" which makes it format XML
927 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
928 JSONText in ECMA-262) is JSONValue, not JSONObject.
932 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
933 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
935 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
936 POSIX/Unix builds .so with major version 4.
938 Remove old LOG_-defines from log.h. They have been obsolete and
939 undefined by default for the last 5 years.
941 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
943 GFS: Remove socket (int *fd) from search_rr handler. The socket
944 descriptor ptr is a facility that allowed a search handler to supply
945 a socket which would serve as a callback - when search was complete.
946 This facility has now been in use for years.
948 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
949 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
950 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
951 returns 'const char *' rather than 'char *. The returned string is
952 read-only and should not be modified by applications. COMSTACK cs_close is
953 now a void function - it no longer returns int. No applications check for
954 the value and the implementations has always returned 0.
956 ZOOM: use size_t for scan hit counts and str size. Functions
957 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
958 occ (hit count) and len (string length) are now of type size_t pointer
959 rather than int pointer. This is to be able to represent large hit counts
960 and to also just to use the proper type for string length (strlen result).
962 New JSON parser. Refer to include/yaz/json.h .
964 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
965 Used to be int in some cases. Many wrbuf_-functions used to return an int
966 indicating some length.. These return values were never used. And so they
969 ODR: odr_malloc, odr_total now takes size_t for size.
971 clone_z_type: fix leak; occurred for encoding failures.
973 --- 3.0.52 2009/12/03
975 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
976 bug was introduced in 3.0.51.
978 --- 3.0.51 2009/12/02
980 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
982 tcpip comstack: fix leak for getaddrinfo.
984 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
985 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
986 Decoding of SRU "path" database is performed by private function
987 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
988 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
990 yaz-client: honor base command for SRU. Change when database setting
991 is applied for SRU and ensure it is kept when a connection is reset.
992 Change also the way errors are displayed or SRU (decoding of packages).
994 --- 3.0.50 2009/11/02
996 Add support for extra request / response data for SRU codecs and GFS.
997 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
998 for extra data response buffer and length. For the GFS, both request
999 and response data (XML) is carried in extra_args and extra_response_data
1000 for the search handler. Patch by Ko van der Sloot.
1002 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1003 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1004 10010). This fixes bug #2113.
1006 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1007 cmdfile included a 'quit' command that would result in a memory violation.
1009 --- 3.0.49 2009/10/01
1011 Make a number of functions defined in xmlquery.c static. These have
1012 never been declared in a public header file (yaz/xmlquery.h) and was
1013 made public by mistake.
1015 Improve speed of character conversions (iconv utilities). This makes
1016 conversions from MARC-8 faster.
1018 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1019 unless type desired is "raw". This will prevent type "xml" from
1020 returning ISO2709 .. Which obviously can not be XML parsed.
1022 Fix memory leak in ZOOM that would occur if option apdulog was used
1023 on a re-used connection.
1025 Frontend server logs HTTP requests.
1027 Frontend server now sends Z39.50 close when it times out (sesssion has
1028 been idle for too long). Versions 2.0.30 and earlier also sent close.
1029 But due to a mistake this was disabled in all versions after that, i.e.
1030 the server would just close the socket immediately.
1032 yaz-client emits a better message when receiving an unrecognised
1033 userInformationField.
1035 Skip zero-length subfields when decoding ISO2709. This rare case happens
1036 if a record has two FS characters in a sequence. Without this patch
1037 there would be a reference beyond char array in using_code_len fragments
1040 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1042 --- 3.0.48 2009/08/28
1044 The show command offered by the zoomsh command now takes a 3d optional
1045 parameter type which is what is passed to ZOOM_record. If the type
1046 argument is omitted, "render" is used.
1048 RPN to CQL conv may use USE string attributes (bug #2978).
1050 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1052 --- 3.0.47 2009/07/08
1054 Function yaz_xml2query allows a diagnostic element in the PQF XML
1055 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1056 code and additional info respectively.
1058 The BER BOOLEAN is now the integral type Odr_bool which still happens
1059 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1060 typedef'd to Odr_int. This is still an integral 'int', but it may be
1061 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1062 ASN-1 compiler as well as programs has been updated to use the new types.
1064 --- 3.0.46 2009/06/08
1066 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1067 only the bibliographic record was rendered. For type=opac, an OPAC
1068 record is only returned if it is present.
1070 iconv: small fix for encoding of advancegreek.
1072 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1074 yaz-client: option auto_reconnect=on really reconnects.
1076 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1078 server: avoid null ptr ref for for yaz_poll errors.
1080 build: fix RPM build for RHEL 5.3.
1082 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1084 --- 3.0.45 2009/03/31
1086 Fixed bug #2709: TCP connect returns Invalid argument.
1088 Fixed compilation for mingw.
1090 Honor charset for raw records (ZOOM_record_get).
1092 Fixed use of errno for threaded mode that was seen on Solaris 10.
1094 Fixed argument passing with blanks in value for Windows Service.
1096 Disable YAZ' own log rotate by default (no 1 GB limit).
1097 The variable l_max_size which specifies the log file limit is set to 0
1098 (DISABLED): This is due to the fact that YAZ is most often deployed using
1099 logrotate. Also YAZ can not perform log rotate because of unsufficient
1100 permissions (setuid).
1102 --- 3.0.44 2009/02/17
1104 List supported encodings in man page for yaz-iconv.
1106 Fixed missing SSL libs for --libs output
1108 Re-established OID record syntax application-xml. Nobody should use it
1109 but we don't want to change soname because of this symbol being absent.
1111 --- 3.0.42 2009/02/02
1113 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1115 Added member named_result_sets for init handler struct for the GFS. This
1116 allows a server to disable named result sets.
1118 Removed OID record syntax application-xml.
1120 Added support for rule-based transliterator for ICU wrapper of YAZ.
1122 Fixed bug #1902: yaz-icu XML output.
1124 Make YAZ checks Emacs friendly.
1126 BITSTRING value shows value. Bug #2346.
1128 ISO2709 decoding: skip control characters from indicator data.
1130 Omit sort key by default in yaz-icu's output.
1132 Allow combined single char options (again) for YAZ' options function.
1134 Utility yaz-marcdump got option to display YAZ version (-V).
1136 Allow YAZ to use ICU 3.4.
1138 Added new ICU test case which illustrates removal of diacritics.
1140 --- 3.0.41 2008/12/29
1142 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1144 --- 3.0.40 2008/12/29
1146 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1149 Fixed bug #2352: yaz-marcdump crashes for certain record.
1151 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1153 Added support for Danmarc2 to UTF-8 conversion.
1155 Added support for ISO5426 to UTF-8 conversion.
1157 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1158 implementation version.
1160 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1162 --- 3.0.38 2008/11/10
1164 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1165 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1167 ZOOM C now interprets databaseName option for ZOOM connection as path
1170 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1172 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1174 Dummy Libxml2 types no longer defined in headers of YAZ'.
1176 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1179 --- 3.0.36 2008/09/26
1181 Various ODR chapter fixes.
1183 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1185 Added missing source for Windows compilation, mutex.c.
1187 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1189 For SRU connections in ZOOM all records up to "count" are now fetched.
1191 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1192 in Windows due to bad error handling for Libxml2.
1194 Added facility for sending arbitrary records (ASN.1 any) using
1195 ZOOM C's Extended service update. Patch by Sam Reynolds.
1197 New options for ZOOM C's connection, logapdu which makes ZOOM log
1200 --- 3.0.34 2008/06/18
1202 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1204 --- 3.0.32 2008/06/12
1206 Fixed memory violation that could occur when decoding UTF-8. This bug
1207 was only present in 3.0.30 of YAZ.
1209 --- 3.0.30 2008/06/06
1211 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1212 GNU TLS is used by default (if found).
1214 yaz-ztest returns OPAC records if a client asks for OPAC.
1216 Improved speed of MARC-8 encoding.
1218 Added support for lossy and loss-less MARC-8 encoding.
1220 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1222 Added new Windows Service wrapper (sc).
1224 yaz-client's itemorder command may now send a file.
1226 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1228 Added new function yaz_log_xml_errors.
1230 Allow (but warn) unknown XML attributes in MARCXML parsing.
1232 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1234 The UTF-8 to MARC-8 conversion now uses a different set of characters
1235 for Greek symbols. Bug #2120.
1237 --- 3.0.26 2008/02/21
1239 Added yaz_daemon (daemon.h).
1241 Fixed bug #2068: pkg-config trouble
1243 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1245 --- 3.0.24 2008/01/28
1247 Document --with-xml2 option.
1249 Added OPAC XML XSD (etc/opacxml.xsd).
1251 Allow glob mask for name attribute in retrieval element for the
1252 generic frontend server's retrieval facility.
1254 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1255 except POLLIN/POLLOUT.
1257 Fixed error handling in cs_listen. Bug #2037.
1259 --- 3.0.22 2008/01/20
1261 Fixed version in yaz/yaz-version.h.
1263 Fixed bug #2027: Crash when closing connection.
1265 Changed configure so that ICU support is only enabled if only ICU
1266 and Libxml2 is available (because the ICU chain is XML based).
1268 --- 3.0.20 2008/01/15
1270 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1271 is built. Only this DLL depends on the ICU runtime.
1273 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1274 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1276 Changed license of CCL module to 'Revised BSD'. After consultation with
1277 remaining members of the original EUROPAGATE consortium, we are re-issuing
1278 the CCL module without a separate license. The software was developed by
1279 Index Data as part of a research project. The special license was included
1280 to help feed usage information back to the project consortium to support
1281 project evaluation. At this time, the project consortium has long-since
1282 disbanded, and the majority of the original principals have retired. At the
1283 same time, we have significantly modified the software during the following
1284 years, to the point where very practically no original code remains. To
1285 simplify re-use of the software, we have contacted those members of the
1286 consortium who could be reached, and agreed to re-issue the module as a
1287 proper part of the YAZ package.
1289 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1291 CQL closer to being version 1.2 compliant. CQL also allows free-form
1292 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1295 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1296 bug could make Extended services handling crash in the ZOOM layer. This
1297 bug was only present in YAZ 3.0.18.
1299 --- 3.0.18 2007/12/19
1301 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1304 yaz-marcdump reads and writes collection wrapped records.
1306 Handle OPAC for record conversion module.
1308 Fixes for ICU wrapper.
1310 Allow ICU libs to be controlled with --with-icu .
1312 --- 3.0.16 2007/11/12
1314 Added yaz_poll which is a wrapper for select/poll. When poll is available
1315 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1316 sockets to be in use.
1318 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1319 functionality through an XML based configuration (ICU chain). This system
1320 is useful for search facilities such as Pazpar2 and Zebra that needs to
1321 perform tokenization of indexed material. The ICU code in a separate
1322 library libyaz3_icu.a.
1324 Added HTTP tunnel facility for COMSTACK, bug #1752.
1325 This is a facility that allows a Web proxy, such as squid, to tunnel
1326 Z39.50 traffic. This facility is "transparent" to must applications
1327 using YAZ. It's enabled by using pseudo transport connect: followed by
1328 the proxy address, followed by command, then follwed by he regular
1329 "virtual" addresss. For example,
1330 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1332 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1334 --- 3.0.14 2007/09/21
1336 Fixed bad memory reference in ZOOM_record - cuased by member not being
1337 initialized. This was a problem only in YAZ 3.0.12.
1339 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1340 fields were not removed.
1342 Changed the way C code is generated from codetables.xml. Made a MARC-8
1343 conversion trie for each characterSet section rather than codeTable.
1344 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1345 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1347 --- 3.0.12 2007/09/12
1349 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1350 from ZOOM_record_error).
1352 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1354 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1356 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1358 Better SRW-to-Bib-1 diagnostic mapping.
1360 ZOOM C and yaz-client announces SRU version 1.2 by default.
1362 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1365 Fixed in yaz_sru_decode to allow other version than 1.1.
1367 --- 3.0.10 2007/08/22
1369 Added support for SRU scan for ZOOM.
1371 Added support for the use of the older versions or Extended Service
1372 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1373 set to the version , 1=first, 2=second, 3=third. The third version is
1374 what ZOOM C has used so far. And that, obviously, is the default.
1376 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1377 therefore in Zebra and in SimpleServer-based applications). The new
1378 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1379 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1380 which is passed into the back-end search callback function.
1382 Added support for HTTP Basic authentication in clients: the SRU/W
1383 codec encodes the username/password elements of the PDU structure
1384 appropriately, and these may be set using the "user" and "password"
1385 options in ZOOM-C applications (the same options that are used for
1386 Z39.50 authentication).
1388 --- 3.0.8 2007/06/25
1390 Fixed bug #1208: SSL appears to be broken in ZOOM.
1392 Fixed bug #1206: Libxml2 include path weirdness.
1394 Added oid_name_to_dotstring.
1396 Allow elementSetName to be specified for ZOOM C record update.
1398 Allow waitAction to be specified for ZOOM C based for Extended Services.
1400 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1401 syntax OID. Bug introduced in YAZ 3 series.
1403 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1405 --- 3.0.6 2007/06/06
1407 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1408 directory. yaz-client now reads commands from file given by option -f
1409 if specified; then tries to read .yazclientrc in current directory.
1410 Failing that, it reads .yazclientrc from user's home directory.
1412 Added support for correlationInfo Note and ID for Record Update via
1415 Added yaz-client command querycharset which specifies character set for
1416 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1417 (termListAndStartPoint).
1419 Charset ISO5428:1984 is an alias for ISO5428-1984.
1421 Implemented a way to perform scan in a result set using Z39.50. This
1422 is achieved by attaching the result set name in the characterInfo
1423 (type InternationalString) of OtherInformation in the Scan Request PDU.
1424 The result set is identified in the otherinformation by the new OID:
1425 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1426 This allows for scan in result set and faceted search . Zebra did some
1427 of this in the APT term using attribute type 8 and value being result
1428 set. Using the OtherInformation approach for this is cleaner and easier
1429 to work with in proxies and the like. This facility can be used in
1430 yaz-client using new command setscan which takes a result set as first
1431 argument, start position (APT) as second.
1433 Changed decoding of SRU XML packed records to deal with servers that
1434 have recordData with XML data with multiple root nodes. Also make
1435 comparison for recordPacking case insensitive. Again, one server
1436 returns "XML" where others return "xml".
1438 For SRU responses allow Content-Type application/xml as well as text/xml.
1440 --- 3.0.4 2007/05/21
1442 Fixed bug in character set conversion of BER strings. Bug introduced
1445 --- 3.0.2 2007/05/08
1447 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1449 For OID class, use oid_class consistently.
1451 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1454 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1455 character set for bibliographic information interchange". By Giannis Kosmas.
1457 Added documentation on new OID API.
1459 --- 3.0.0 2007/05/02
1461 Changes to generic frontend server interface: added new member
1462 'query_charset' for bend_initrequest structure. A backend init handler
1463 should set this member to its native character set for query terms.
1464 When defined, the frontend server logic will announce this character set
1465 to a client if the negotiationModel bit is set by the client. All server
1466 implementors are encouraged to specify this. If a backend server does not
1467 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1469 Added CCL utility to remove terms (stop words) from resulting RPN
1470 tree. This is handled by functions with prefix ccl_stop_words_ .
1472 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1473 terms in RPN queries.
1475 Clean-up the CCL API. Moved some internal structures from ccl.h to
1476 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1477 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1478 This is replaced by ccl_parser_find_str which takes a string instead.
1480 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1481 libyaz.la is the core of YAZ except the generic frontend server and
1482 does not depend on POSIX threads anymore. libyaz_server.la is the
1483 generic frontend server facilities and uses POSIX thread functionality
1484 if available. The libyaz.la no longer depends on POSIX threads because
1485 the number of global structures is limited. NMEM no longer re-uses blocks
1486 between threads ; it simply free's memory immediately but allocates in
1487 "large" chunks as usual. We don't expect any performance penalties
1488 because of this. The yaz_log system is still using a global log_level so
1489 caution must be taken when modifying it with yaz_log_init_.. +
1490 yaz_log_mask_str. This, however, should not cause any trouble because
1491 these functions are called during initialization of application code
1492 anyway. `yaz-config --libs server` returns libs for server applications;
1493 `yaz-config --libs` returns libs for non-server applications.
1495 New OID database - with public definitions in oid_db.h. Removed old OID
1496 database including the head oid.h and definitions such as enum oid_value
1497 and struct oident. The new OID database uses the same string names as
1498 before but the 'protocol' is gone. There are now only two representations
1499 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1500 converts from string to OID; functions with prefix yaz_oid_to_string
1501 converts the other way.
1503 Change to emit_term() in CQL-to-PQF query translation: when a term has
1504 the /regexp relation modifier, do not process it for leading and
1505 trailing "^" and "*", which have quite different meanings in regular
1508 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1509 write handlers no longer carries a 'last' parameter. This will make
1510 yaz_iconv flush "less" characters. A flush is performed by call to
1511 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1513 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1514 removed, because function yaz_query_to_wrbuf does the same.
1516 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1517 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1519 Deprecated MARC utility functions removed.
1521 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1524 Branch split: YAZ_2_1_55_branch
1526 --- 2.1.54 2007/03/16
1528 Fix to ZOOM-C so that transparent reconnection is properly handled on
1529 connections that are in asynchronous mode.
1531 Fixed compilation on OpenBSD 4.0.
1533 Large strings in GRS-1 records are now properly displayed in yaz-client.
1535 Added character conversion support for "advancegreek"; based on patch from
1538 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1539 sequence is met. Before the error was not set so it would be unknown.
1541 Adjust yaz-marcdump MARC reader so that it skips until record separator
1544 --- 2.1.52 2007/03/07
1546 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1547 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1548 fd_set structure used as a bitmask for the FDs to be selected on.
1550 Using ACX_PTHREAD macro to check for POSIX threads.
1552 Fixed have-vsnprintf check.
1554 --- 2.1.50 2007/02/23
1556 Fixes for configure on BSD. Bug #900.
1558 Added snprintf/vsnprintf wrappers for systems that don't have
1559 limits (heavens forbid).
1561 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1562 created before all previous tasks were completed and removed from the
1563 task queue, the new task could be removed by a mistake.
1565 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1567 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1569 Fixed bug #832: Problem with MARC/charset in yaz-client.
1571 Fixed bug #668: save command line history for yaz-client.
1573 Fixed bug #830: pkg-config support.
1575 --- 2.1.48 2007/01/23
1577 Extended ZOOM result set options with two options that may be read by
1578 a client: resultSetStatus and presentStatus with values as specified for
1580 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1582 Fixed bug #827: Using SSL fails on Debian etch.
1584 Fixed bug #826: Weird looking chars for set of MARC records.
1586 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1587 that is treated as an ItemOrder with itemRequest being an XML document
1588 external. The value of "doc" is the content.
1590 Extended the GFS search facility. New member of bend_search_rr
1591 'estimated_hit_count' signals that hits is known to be an estmate
1592 (higher or lower than real hit count). New member 'partial_resultset'
1593 signals that the search was partial (hit count is lower or equal than
1594 real hit count). For Z39.50, the information is stored in resultSetStatus
1595 member of SearchResponse APDU. For SRU, the information is signalled
1596 via SRU diagnostic 59: "Result set created with valid partial results
1599 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1601 --- 2.1.46 2007/01/13
1603 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1605 Added ZOOM_connection_peek_event.
1607 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1608 the following new functions:
1609 ZOOM_event_nonblock, ZOOM_connection_process,
1610 ZOOM_connection_get_{socket,mask,timeout},
1611 ZOOM_connection_fire_event_{timeout,socket}.
1612 The existing blocking event handler, ZOOM_event, is a wrapper for the
1613 + blocking ZOOM_event_sys_{poll,select}.
1615 Implemented function ccl_xml_config which parses XML version of CCL
1616 configuration (bug #798).
1618 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1620 Added timings utility (yaz/timing.h)
1622 --- 2.1.44 2007/01/03
1624 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1627 Fixed bug #779: Rotation of apdu.log fails.
1629 Fixed for character set conversions:
1630 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1631 Honor G1 set in MARC-8 decoding.
1633 --- 2.1.42 2006/12/17
1635 Fixed bug #775: char conversion does not handle Alternative UTF-8
1638 Implemented function yaz_marc_read_line which parses MARC line format
1639 records. There is a wealth of formats out there. So far, this function
1640 reads line records produced by yaz_marc_write_line.
1642 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1643 more generic and easier to remember(!) options: -i format and -o format
1644 which specifies input format and output format respectively - where
1645 format is one of "marc", "marcxml", "line", "marcxchange".
1647 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1648 does not print anything except warnings for records.
1650 For yaz-marcdump, added support for MARC split into files (-s) with a given
1653 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1654 spec, at http://www.loc.gov/standards/sru/record-update/
1655 This has changed the binary layout of the following structs:
1656 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1657 bend_update_rr . Patch by Ko van der Sloot.
1659 Added GFS utility function bend_assoc_is_alive which returns 1 if
1660 association is still alive (client is connected); 0 otherwise (client
1661 closed connection). This allows busy servers to stop working for
1664 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1665 been a separate piece of software. This version of ziffy has been modified
1666 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1668 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1670 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1671 Client code may now interrogate options such as "init_opt_sort" to
1672 find out whether the server claims to support various options.
1674 --- 2.1.40 2006/11/27
1676 Added utilities yaz_{set,get}_esn to set/get element set name from
1679 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1680 of YAZ and has been so since YAZ 2.1.10.
1682 Implemented ZOOM_record_error which returns error information for
1683 record (surrogate diagnostic).
1685 --- 2.1.38 2006/10/31
1687 Updates for SRU Update by Ko van der Sloot:
1688 1. Changed name from "operation" to "action"
1689 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1690 versions in the code, marked as 'backward compatible'.
1691 3. Added diagnostics for SRU Update.
1693 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1695 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1697 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1699 For GFS, fixed problem with SRU diagnostic 'First record position out of
1700 range' being issued for 0 hits.
1702 zoomtst10 part of Windows Build.
1704 --- 2.1.36 2006/10/13
1706 Implemented yaz_filepath_comp which splits a path into file path
1707 components (required by Zebra 2.0.3+).
1709 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1710 BSD inspired license until now so this should not have any real impact on
1711 anybody. See http://www.opensource.org/licenses/bsd-license.php
1713 Fixed bug #687: Missing log lines.
1715 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1718 Fixed bug #689: SRU diagnostics to be added.
1720 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1721 whether a connection is idle (no more work do do).
1723 --- 2.1.34 2006/10/04
1725 Change type of optval from long to int for invocation of setsockopt with
1726 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1728 Added support for specifying the max log file size for the Generic
1729 Frontend Server. The size is given with option -r.
1731 --- 2.1.32 2006/09/21
1733 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1735 --- 2.1.30 2006/09/17
1737 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1740 Fixed bug in Generic Frontend Server that could cause a server to stop
1741 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1743 For the generic frontend server, the maximum record size is used as maximum
1744 size of incoming packages (SRU + Z39.50). The value until was previously
1745 only used in Z39.50 Init negotiation and, later, in a session controlled
1746 sizes of records returned. This is controlled using -k option. It can be
1747 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1749 --- 2.1.28 2006/09/04
1751 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1754 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1756 New option for yaz-marcdump -lpos=value which allows setting a portion
1757 of MARC header to a certain value.
1759 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1761 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1762 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1764 --- 2.1.26 2006/08/15
1766 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1769 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1771 --- 2.1.24 2006/08/08
1773 Fixed MARC ISO2709 encoding routines to deal with character set
1776 Minor changes to GFS logging. Database included in search request log
1779 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1780 cached/multiple records.
1782 Shared libraries are built by default on Unix+configure.
1784 Changed cql2pqf transformation to use a different evaluation order. The
1785 new order is: always, relation, structure, position, truncation, index
1786 and relationModifier. Old order was: always, relation, relationModifier,
1787 structure, index, position, truncation. Note that the the latter ones
1788 override former ones for identical attributes.. The new scheme means that
1789 it is possible to override any existing attribute with a relationModifier.
1790 And also that it is possible to override everything for the index rule
1791 (except the ones listed in relationModifier). No order is perfect but this
1792 one, we believe, covers more real cases.. The "always" should have been
1793 called "default", since the attributes there can be overridden with all
1796 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1797 compilation phase, but also for yaz-config --cflags output. This allows
1798 us to have public headers with Libxml2 stuff in them . It should also,
1799 eventually, make Libxml2 checks redundant in packages using YAZ, such
1802 --- 2.1.22 2006/06/15
1804 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1805 stored in uri, message and details.. Previously diagnostics were stored
1806 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1807 compatibility.. but he's probably the only one affected, so.
1809 Added support for CCL, compiled on the client side, in ZOOM-C. This
1810 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1811 input; the resulting query objects can be used for for searching with
1812 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1814 YAZ' configure searches for OpenSSL by default.
1816 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1817 SL_CTX_use_certificate_file. See
1818 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1819 for more info. Thanks to Ko van der Sloot.
1821 --- 2.1.20 2006/06/02
1823 Bug #600: SRU GET, POST support for yaz-client. Introduced
1824 command 'sru' which selects method SOAP/GET/POST.
1826 Allow missingValueAction to be specified for the sortspec string -
1827 function yaz_sort_spec. By default, the missing value action is null.
1828 Use ! to specify "abort". Use = followed by stringvalue to specify default
1831 Ensured that Present-handler (if defined) is called in GFS before any call to
1832 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1833 searchRetrieve requests.
1835 Documentation for YAZ is now based on the Docbook XML/XSLT using
1836 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1837 is no longer depending on jade/openjade or docbook-to-man scripts.
1838 PDF is no longer part of the distribution - but can optionally be
1839 made using DSSSL/jadetex or FOP.
1841 Added retrieval handling support in Generic Frontend Server to support
1842 conversion between MARC/XML as well as XSLTtransforms. See
1843 etc/yazgfs.xml for an example.
1845 Added Authentication support to Generic Frontend Server in SRU
1846 mode. Authentication using HTTP Basic is supported, as is the use
1847 of 'x-username' and 'x-password' parameters in the request itself.
1849 Added support for a new character set MARC8s identical to MARC8 except
1850 that it converts combined characters to single Unicode characters in the
1851 Latin-1 range (when possible).
1853 --- 2.1.18 2006/04/24
1855 ASN.1 compiler 0.4: generates brief Doxygen file header for
1856 generated .h/.c files.
1858 Utility yaz_iconv now supports conversion to MARC-8.
1860 New facilities for the MARC module. The reading - and writing of
1861 content are separate methods for the yaz_marc_t handle. The following
1862 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1863 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1864 format). Write functions have prefix yaz_marc_write_.. The existing
1865 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1866 available. Removed support for OAI-MARC and simplexml (not the
1867 simplexml from PHP5).
1869 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1870 to be returned for this connection.
1872 --- 2.1.16 2006/03/31
1874 Allow multiple languages and charsets to be specified with
1875 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1876 negcharset iso-8859-1,utf-8
1878 Translation of proximity nodes from CQL into PQF now works.
1880 Moved to automake 1.8, 1.9.
1882 Added function yaz_log_set_handler which allows a log handler to be
1883 installed. This handler will be called for all log messages. Output
1884 to file is also produced; but that can be disabled by passing NULL
1885 fname to yaz_log_init_file.
1887 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1889 For SRW (including GFS), accept application/soap+xml as content-type
1892 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1893 produces NO stylesheet reference even if a default stylesheet is specified
1896 --- 2.1.14 2006/03/14
1898 Updated Windows package to include yazd.dll + yazd.lib for the
1899 Development component.
1901 If the environment variable YAZ_LOG is set, then it is used as a
1902 string indicating the default level of logging to use if not
1903 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1904 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1905 used as before. So, for example, to omit warnings from YAZ logging,
1906 export YAZ_LOG=-warn
1908 cql_transform() now map structure and other attributes before indexes,
1909 so that index-specific structures and other attributes can override
1910 defaults. So now a combination of mapping specifications such as:
1912 index.dc.date = 1=date-modified 4=5
1913 does the right thing.
1915 cql_transform() now also respects the "always" mapping specification,
1916 which establishes an initial set of attributes to be used for all
1917 terms except where overridden by more specific attributes associated
1918 with the index, relation or modifier.
1920 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1921 which mode to use; one of "post", "get" or "soap" (SRW, default).
1923 Fixes for yaz_iconv routines: changed trie-based character set conversions
1924 to use only non-negative values for bit fields due to Sun's C compiler not
1925 supporting negative values.
1927 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1928 sequences where not read correctly. Fix by Rustam Usmanov.
1930 Updated win/makefile to use options, settings which makes things
1931 compile with VS C 2005.
1933 --- 2.1.12 2006/02/01
1935 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1937 In ZOOM socket code, use select instead of poll on MacOSX.
1939 ZOOM-C now support client-side compilation of CQL into RPN that is
1940 sent to the server, enabling CQL to be used against all Z39.50
1941 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1942 ZOOM_query object, and submit it using ZOOM_connection_search().
1943 The CQL-to-RPN translation uses a configuration file, the name of
1944 which must be specified in the Connection's "cqlfile" option.
1946 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1947 function, which takes as its start-term parameter a ZOOM_query object
1948 (which may have had either CQL or RPN set into it).
1951 --- 2.1.10 2005/11/29
1953 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1954 GFS to support this as well. Backend handler, bend_srw_update, does the
1955 update work. Code contributed by Ko van der Sloot.
1957 Allow retrieval of Search Result-1 information in ZOOM by the use of
1958 options that are attached to a result set. ZOOM documentation updated
1961 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1962 UTF-8 conversion. Patch by Raj Patel.
1964 Added option -m to GFS to control formatting of timestamps in log file.
1966 Added 'exit' as synonym for 'quit' in yaz-client
1968 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1969 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1970 for the new members. Patch by Ko van der Sloot.
1972 Added support for SRU POST. It is supported for content-type
1973 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1975 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1976 Instead make the library libyaz.la multi-threaded. Threading as a whole
1977 can still be disabled by configure option --disable-threads. Previosly,
1978 with older GLIBCs there were problems with MT libs under Apache. This
1979 has now been fixed a long time ago.
1981 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1984 CQL module modified to be case insensitive for relations/indexes/operations.
1986 Fixed bug in CQL transform code: incorrect value relationModifieder
1989 Added 'show all' command for yaz-client which retrieves all results
1992 Added new yaz-client, xmles, which takes a (private) OID and
1993 a document to be sent as an extended service request.
1995 Describe new yaz-client commands wait_response and set_auto_wait.
1997 Increase TCP/IP listener backlog from 3 (which I am guessing was
1998 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1999 that the socket will queue as many incoming connections as it's able
2000 to handle ongoing connections. In other words, it will never now
2001 refuse a connection that it would be able to handle merely because
2002 it's not got around to accepting() enough of the pending connections
2003 yet. This is the behaviour anyway under Linux, where the listen()
2004 argument is ignored; but not under BSD and on systems such as
2005 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2006 YAZ-based servers should now be uniform across operating systems in
2009 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2010 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2011 This allows yaz-marcdump to read large MARC batches (>2 GB).
2013 Modified all YAZ source files - except the source which is auto-generated
2014 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2017 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2018 corresponding to the existing *_setl() function. These allow option
2019 values containing arbitrary valuues.
2021 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2022 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2023 except that it returns an indicator of whether or not the sort
2024 criterion was accepted (0 for OK, -1 for invalid).
2026 --- 2.1.8 2005/06/07
2028 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2029 MARC output rather than returning "new" buffer.
2031 yaz-client warns about unknown init options.
2033 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2035 --- 2.1.6 2005/05/24
2037 Added support for SRW sort in Generic Frontend Server. Patch
2038 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2039 sortKeys - or NULL if none is provided.
2041 Fixed bug #307: It was impossible to specify indefinite/no timeout
2042 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2045 Added support for multiple languages and charsets to be specified in
2046 ZOOM. Each charset/language is separated by a blank. If negotiation is
2047 in effect in init-response, Option
2048 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2049 Code based on patch by Vasiliy Osadchuk.
2051 Fixed bug #306: infinite recursion that occurred when calling
2052 yaz_log_level_init as the first call (before other log level or
2055 Fixed bug in scan handling in front end server: if preferred-Position-In-
2056 Response was non-present, a NULL pointer referece was performed.
2058 --- 2.1.4 2005/04/26
2060 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2061 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2062 now defined for all those error codes. So instead of putting 109 in
2063 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2064 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2066 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2069 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2071 Program yaz-client now exits and produces an error message if multiple
2072 Z39.50 servers are specified on the command line (none or one allowed
2075 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2078 --- 2.1.2 2005/03/16
2080 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2082 Fixed bug #272: Preserve spacing for CCL terms.
2084 --- 2.1.0 2005/03/14
2086 Added support for virtual hosts and multiple backend servers for
2087 the YAZ frontend server. The configution is XML based and
2088 support specificition of CQL to RPN mappings and explain information.
2089 See section "Virtual Hosts" in the YAZ manual.
2091 Extended OPAC display utility. OPAC display utility renders
2092 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2093 to supplement yaz_marc_decode_wrbuf.
2095 Fixed a bug in MARC decoder that could caused it to crash for some
2096 invalid MARC records. More diagnostics and warnings where added in
2097 XML output (warnings, etc are stored in comments).
2099 --- 2.0.34 2005/02/08
2101 Fixes for UNIX domain sockets. Bug #261.
2103 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2105 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2106 Added yaz_marc_subfield_str which defines subfield lead string which is
2107 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2108 yaz_marc_endline_str which defines end of fields string used in
2109 YAZ_MARC_LINE format. Default string is newline.
2111 Experimental support for MarcXChange. This format can be produced
2112 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2113 http://www.bs.dk/standards/MarcXchange.xsd
2115 Added yaz-client commands scansize that sets maximum number of
2116 entries to be returned by scan.
2118 --- 2.0.32 2005/01/11
2120 Added support for SRW scan in yaz-client and Generic Frontend Server.
2122 * Added whereInList member to SRW Scan Term.
2124 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2126 Fixed NMEM system to return aligned blocks on the smallest boundaries
2127 that are suitably aligned for all possible types on the particular
2128 architecture YAZ is being built for.
2130 --- 2.0.30 2005/01/04
2132 Fixed numerious warnings that was issued with newer versions of GCC.
2134 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2135 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2138 Make YAZ Generic Frontend Server slightly faster.
2140 Enhance (and reduce) logging for Generic Frontend Server.
2142 Revert YAZ log system so that it flushes every write operation
2143 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2145 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2146 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2147 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2148 will effectively disable old definitions.
2150 --- 2.0.28 2004/11/09
2152 Added yaz_log_time_format which specifies log format using
2155 Added yaz_log_module_level which returns mask for a module. Value
2156 is non-zero mask a if module is enabled; zero if disabled.
2158 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2159 in include/yaz/cql.h.
2161 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2163 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2165 Fixed bug #172: RPM builds does not enable SSL.
2167 Doxyfile.in part of dist. Doxyfile generated by configure.
2169 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2170 are given and the corresponding component does not exist.
2172 Extend CCL documentation in YAZ reference. Describe r=r.
2174 --- 2.0.26 2004/10/01
2176 Fixed MARC->MARCXML conversion to properly deal with
2177 fields, subfields, indicators having non-ASCII characters.
2179 Fixed MARC->MARCXML conversion so that ASCII control characters
2180 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2183 Added YAZ GFS support for conversion from Z39.50 surrogate
2184 diagnostics to SRW surrogate diagnostics.
2186 Bug fix: YAZ GFS did not return schema in explainResponse.
2188 --- 2.0.25 2004/09/30
2190 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2191 now converts recordSchema to elementSetName as well as schema URI.
2193 Fixed bug in COMSTACK that prevented HTTP request packages from being
2196 --- 2.0.24 2004/09/29
2198 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2199 does not require white-space before and after the dash in a range, e.g.
2200 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2203 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2204 due to new GCC removing "redundant" code.
2206 Added yaz-client commands scanpos and scanstep that sets preferred
2207 position and step-size for scan.
2209 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2211 Added CCL utility ccl_qual_buf which parses one or more CCL
2212 spec lines in a buffer.
2214 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2215 of name and value - ignoring empty lines and comments.
2217 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2219 Added odr_get_element_path which returns current element path for an
2220 ODR handle. This utility is useful in error handling or user-defined
2223 Added ODR_PRINT utility odr_set_stream which is is a more generic
2224 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2225 to a write function and pointer to close function. The close function - if
2226 non-NULL - will be called during odr_destroy.
2228 Fixed bug in CCL parser where truncation char was not removed from
2229 right side when truncation=both was in effect.
2231 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2234 --- 2.0.23 2004/08/11
2236 Fix buffer overrun in CQL parser when dealing with proximity (%).
2238 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2239 to UTF-8/UCS conversion is now only based on codetables.xml.
2241 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2243 --- 2.0.22 2004/08/06
2245 Add support for more "commit changes" in ZOOM (uses Extended Services).
2247 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2250 Yet another small fix for configure of SSL.
2252 --- 2.0.21 2004/05/14
2254 Fix SSL libs for configure when --with-openssl=DIR is given.
2256 --- 2.0.20 2004/05/10
2258 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2260 SSL comstack now uses yaz.pem certificate file on server side
2261 by default. Certificate filename can be configured by calling
2262 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2264 Fix bug regarding multiple calls to ZOOM_connection_connect.
2266 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2268 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2269 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2271 ZOOM now allows inspection of X509 peer certificate for verification.
2272 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2274 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2275 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2276 as "modular" but it simplifies things.
2278 Added cs_get_peer_certificate to that returns peer X509 PEM.
2280 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2281 NULL if SSL is unavailable.
2283 Documentation about MARC decoding tools.
2285 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2287 --- 2.0.19 2004/03/30
2289 Rename CHANGELOG to NEWS to follow GNU style packing.
2291 Fix bug with missing initialization of member in init_diagnostics.
2292 This bug affects threaded version of GFS server.
2294 --- 2.0.18 2004/03/20
2296 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2299 Ensure zlib.dll is packed with Windows install.
2301 --- 2.0.17 2004/03/17
2303 Fix encoding of xsd:string to use text instead of CDATA.
2305 Fix endless loop in CQL parser with unbalanced ".
2307 Use a more compact way to store MARC-8 conversion tables.
2309 --- 2.0.16 2004/03/16 Debian only
2311 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2314 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2319 --- 2.0.15 2004/03/01
2321 Another fix for decoding of XML packed records.
2323 --- 2.0.14 2004/02/25
2325 Fixes for Chunked encoding. White space not ignored after length spec.
2327 Update NS and use default NS for SRW diagnostic elements.
2329 --- 2.0.13 2004/02/23
2331 Implement ZOOM_resultset_cache_reset which resets record cache.
2333 Implement ZOOM_resultset_sort which sorts a result set.
2335 Implement chunked HTTP transfer.
2337 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2339 --- 2.0.12 2004/02/16
2341 Added member 'schema' to bend_explain_rr structure so that backend
2342 can specify explain record identifier. Defaults to Zeerex 2.0.
2344 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2346 --- 2.0.11 2004/02/16
2348 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2351 Added init command for yaz-client which sends "extra" init request.
2353 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2354 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2356 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2358 Make ZOOM error code for "invalid query".
2360 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2362 --- 2.0.10 2004/02/05
2364 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2367 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2369 Added option -p <file> to make Generic Frontend Server to write PID file.
2371 Added option -D to put Generic Frontend Server in background on its own.
2373 Make ZOOM C recognize option "password". If unset, "pass" is used
2374 (for backwards compatibility).
2376 Fixed a bug in Generic Frontend Server that could make it crash if a
2377 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2380 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2381 Must be issued before open, in order to be in effect.
2383 --- 2.0.9-6 2004/01/12 Debian/Windows
2385 Make the SRU server more picky WRT unknown params, etc.
2387 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2389 New YAZ client command, options, that sets Z39.50 options.
2391 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2392 options from a string of tokens (one token for each option bit).
2394 Update SRW diagnostic code messages.
2396 --- 2.0.9-5 2004/01/07 Debian/Windows
2398 Handle user defined stylesheet for SRW/SRU.
2400 --- 2.0.9-4 2004/01/06 Debian/Windows
2402 Fix bug in decoding of Content-Length.
2404 --- 2.0.9-3 2004/01/06 Debian/Windows
2406 Fix a bug with decoding of XML packed records.
2408 --- 2.0.9-2 2004/01/05 Debian only
2410 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2412 Fix bug in SRW/SRU diagnostics decoding.
2414 --- 2.0.9 2004/01/05
2416 Fixed bug in Generic Frontend Server which could drop records exceeding
2417 preferred message size. Reported and fixed by Irina Dijour.
2419 Fixed calculation of package size for structured records in Generic
2420 Frontend Server. Reported and fixed by Irina Dijour.
2422 Fixed namespace for SRW/SRU diagnostics.
2424 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2426 --- 2.0.8 2003/12/22
2428 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2429 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2432 CQL changes to reflect recent changes to the specification:
2433 * Documentation talks about context sets instead of index sets.
2434 * Documentation talks about indexes instead of qualifiers.
2435 * The CQL-to-PQF transformer's configuration file now uses
2436 "index.set.name = <attributes>" instead of the old form
2437 "qualifier.set.name = <attributes>". (Both forms are still
2438 understood but the latter is deprecated.)
2439 * CQL terms with no explicit index specified are now interpreted as
2440 cql.serverChoice instead of srw.serverChoice (which of course
2441 behaves exactly the same.)
2443 --- 2.0.7 2003/12/16
2445 MARC conversion can now generate ISO2709 output in another
2446 character set. yaz-marcdump uses this facility if you invoke it
2449 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2450 functions from there can be used from C++.
2452 --- 2.0.6 2003/12/04
2454 Frontend server now transfers memory from decoded packages to stream
2457 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2458 references to show up.
2460 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2461 the ZOOM Abstract API. The older names for the same options are still
2462 also supported for the benefit of old applications.
2464 ZOOM-C supports "implementationId" and "implementationVersion" options
2465 to go along with "implementationName". These allow the user code to
2466 specify identification strings to be sent to servers.
2467 Add OID for the new ExtLite attribute set.
2469 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,

2472 For generic frontend server, reverse the order of
2473 "toolkit-supplied / application-supplied" strings sent as implementationId,
2474 Name and Version. Also, remove the spaces around the slash. This brings
2475 the GFS in line with the behaviour of ZOOM-C on the client side.
2477 Add function ZOOM_scanset_display_term.
2479 yaz-client shows scan displayTerm if present.
2481 Utility yaz-iconv is now installed by default along with the man page
2484 Extend configure check for OpenSSL to use pkg-config where available (such
2487 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2488 server to specify uid/gid/mask for socket using the format
2489 unix:[user=uid,][group=gid,][umask=mask,]file=path
2490 If file= is omitted the existing format is assumed, e.g.
2492 in which case the mask is 0666 (rw for everybody).
2494 Major restructure of YAZ source. All source in libyaz is in src directory.
2495 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2496 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2498 Added man page for utility yaz-marcdump (used to be called marcdump).
2499 yaz-marcdump is installed by 'make install'.
2501 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2502 of incoming package failed.
2504 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2506 Change prototype of odr_perror: add const to message string.
2508 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2510 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2511 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2512 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2513 DNS lookup. There should not be any compatibility problems with this
2514 assuming that blocking=1 or 0 is used.
2516 Fix bad reference in UNIX comstack in function cs_addrstr.
2518 Fix for compilation on AIX.
2520 The generic front-end server (server/seshigh.c) now supports returning
2521 Init diagnostics to the client in User-information-field, in
2522 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2525 --- 2.0.4 2003/09/04
2527 Allow any CQL relation (not just all,any,exact,scr).
2529 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2530 that features the same UI.
2532 Implemented command update0 in YAZ client which is equivalent to
2533 update but uses old of Ext Update ASN.1.
2535 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2536 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2537 Previously no OID was used for this info.
2539 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2540 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2541 returns 'malformed search term' otherwise.
2543 SortResponse member resultCount now set to NULL in sort handler of
2546 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2549 Add three new utility functions for translating OIDs between various
2550 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2551 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2552 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2553 char *oid_to_dotstring(const int *oid, char *oidbuf);
2554 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2556 Reverted modifications for ES Update definition for z_IU0Update
2557 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2558 is back to YAZ 2.0.2.
2560 String value attributes for CCL parser.
2562 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2563 which their FirstSearch server returns in Init responses, sometimes
2564 carrying useful diagnostic information when Init fails. This has the
2565 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2566 "z39.50/oclcui.asn", where its definition is somewhat different from
2567 what OCLC document on their web-site, as required to interoperate with
2570 Support for anonymous authentication in yaz-client. Use the command
2573 * Fix the OID of the Index Data-local "admin" Extended Service from
2574 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2575 the 1000, which indicates a locally-defined OID, was a mistake.
2577 --- 2.0.3 2003/06/20
2579 Fix CCL directive @case handling so that it affects string match for
2580 both CCL keywords and qualifiers.
2582 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2583 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2584 Decoder has been updated with ASN.1 changes as listed in
2585 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2586 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2587 z_IUUpdate, remains unchanged.
2589 ZOOM_record_get may now return a record in a specific character set.
2590 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2591 "from" is the character set of record as returned by target. "to" is
2592 the character set to be returned. If omitted, "to" is UTF-8.
2594 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2596 New ODR utility, odr_getelement, which returns name of element for
2597 which encoding/decoding failed.
2599 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2600 in cases where a required element was omitted.
2602 Bug fix: some MARC8 sequences were not converted.
2604 New ZOOM option "step" which specifies number of records to be
2605 retrieved in one chunk. Used in conjunction with "start" and "count".
2607 SRW support for yaz-client. Use scheme http: to use it, e.g.
2610 yaz-client no longer does (un)intelligent character set conversions
2611 by default. Can be enabled with charset and marc_charset commands.
2613 xmalloc trace fix for 64-bit systems such as DEC alpha.
2615 Solaris 2.6 compile fix.
2617 New function, cql_strerror() translates SRW error codes, as returned
2618 by cql_transform_error(), into human-readable English strings. Used
2619 in yaz-client diagnostics when appropriate.
2621 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2622 converts it into a type-1 query which is sent to the server. This
2623 makes CQL available for use with all Z-servers, as opposed to the tiny
2624 minority that can handle CQL queries themselves.
2626 --- 2.0.2 2003/04/28
2628 New Debian package layout similar to the Redhat Package layout.
2630 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2631 and search result respectively.
2633 --- 2.0.1 2003/04/25
2635 Redhat package is now several packages: libyaz (runtime libraries),
2636 libyaz-devel (development and documentation, and yaz (utility programs).
2637 Package spec file by Morten Bogeskov.
2639 New member 'schema' in struct bend_fetch_rr which the name of requested
2640 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2641 handler MAY set this to reflect the schema of the returned record.
2643 New member 'display_term' in struct scan_entry. GFS now sets member entries
2644 and allocates scan entries to be filled by user scan handler. In previous
2645 version, entries member was allocated by the scan handler. That still works,
2646 but the GFS will ignore member display_term - assuming it was NOT set by
2647 the handler. The fact that the GFS now allocates the entries both allows
2648 for new members and makes a scan handler easier to write.
2650 Fix CQL lex buffer overflow.
2652 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2653 SRU default recordPacking is string.
2655 SRU protocol support for frontend server.
2657 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2659 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2661 Added scan for the ZOOM shell (zoomsh).
2665 * String Identifers for Schemas (Amendment 5).
2666 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2667 Old definition for schema
2668 Odr_oid *schema; /* OPT */
2673 Z_InternationalString *uri;
2674 #define Z_Schema_oid 1
2675 #define Z_Schema_uri 2
2678 * resultCount parameter to Sort Response (Amendment 1).
2679 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2681 Support for SRW 1.0 over HTTP. This is an optional feature and
2682 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2685 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2686 on the same port. SRW SearchRetrieveRequests are mapped
2687 to bend_init,bend_search,bend_fetch,bend_close.
2689 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2691 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2692 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2694 ZOOM connections are SRW based if schem http is used for hostname
2695 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2696 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2698 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2699 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2700 distance=n, order=true/false, relation=le, prox unit=word. If
2701 n is omitted, distance 1 is used.
2703 Fixed problem with C compiler include path in wrong order.
2705 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2706 on Solaris. Patch from Ko van der Sloot.
2708 New MARC decode API. All new functions operate on a yaz_marc_t
2709 handle. The most important new functions are: yaz_marc_create,
2710 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2711 decode and destroy respectively. Decoder can produce formats
2712 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2713 include/yaz/marcdisp.h.
2715 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2716 to UTF-8, UCS-32, wchar_t or Latin-1.
2718 * Prototypes for yaz_iconv_-functions moved to separate header
2719 include/yaz/yaz-iconv.h.
2721 Make a few private functions 'static' in unix.c. This prevents
2722 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2724 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2725 are set when Init Response is received.
2727 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2728 but returns diagnostic set as well.
2730 New function yaz_strerror which is a portable wrapper for
2731 strerror/strerror_r/GetLastMessage.
2733 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2734 is returned for MARC. If type is "oai", then OAI MARC is returned.
2736 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2739 --- 1.9.2 2002/11/26
2741 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2743 Fix bad race conditions on SIGTERM and terminate gracefully in
2746 Move retrieval (data1) module to Zebra since nobody seems to be
2749 Add GRS-1 render for ZOOM using same format as yaz-client.
2751 --- 1.9.1 2002/10/05
2753 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2755 Fix broken ESpec handling in data1 module.
2757 SGML reader parses comments and makes them part of the data1 tree.
2759 Added several type casts so that YAZ compiles as C++ code.
2761 ZOOM didn't handle PDU encoding failures properly.
2763 Added more Bib-1 diagnostics (approved extensions).
2765 GNU configure: better check for iconv.
2767 More portable use of accept, getpeername. Check for socklen_t. Use
2768 int/size_t if socklen_t is not defined.
2772 PQF parser rejects bad queries - including those with extra
2773 characters in them. PQF parser used to silently ignore that.
2774 Cleaner API for PQF added, which allows you to get detailed
2775 error information for bad queries (see yaz/pquery.h).
2777 Fixed bug in ZOOM_record_get for type "database".
2779 Implemented mini iconv library supporting conversions between
2780 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2782 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2784 --- 1.8.9 2002/08/20
2786 Fixed ZOOM C record cache so that preferredRecordSyntax and
2787 elementSetName is used to check for already fetched records.
2789 --- 1.8.8 2002/08/02
2791 Added three members in bend_initrequest structure to facilitate
2792 character set negotiation.
2794 Fixed a bug in frontend server that could cause indefinite
2795 loops under rare conditions.
2797 Revised character set utilities (charneg.h) so that encoding
2798 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2800 For PQF, directive @term <type> sets term type for Scan/Search.
2801 Here <type> is general, string, numeric, null. The term type
2802 is inherited - just like @attr.
2804 New call odr_set_charset that sets character set conversion for
2805 international-strings on a ODR stream. Prototype is:
2806 int odr_set_charset(ODR o, const char *to, const char *from);
2807 The InternationalString is still represented as C string in YAZ
2808 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2809 won't). On the protocol level, you can use any encoding.
2811 Support for UNIX sockets in ZOOM.
2813 Solaris recv sometimes returns errno == ENOENT. It is treated as
2814 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2816 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2817 both client and server. Code by Morten Bogeskov.
2819 --- 1.8.7 2002/05/22
2821 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2822 that they can be used directly from Visual Basic. You must recompile
2823 your windows APP if you're using ZOOM.
2825 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2826 Commands "lang" and "charset" sets language and character set respectively.
2827 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2828 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2830 Attributes from multiple CCL fields may be OR'ed rather than merged
2831 using directive "@field or". Fields are still merged by default -
2832 equivalent to "@field merge".
2834 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2837 Fixed bug in zget for parameter ExtendedServicesResponse.
2841 --- 1.8.6 2002/03/25
2843 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2845 Client displays USR.1:SearchResult-1 (hits per term).
2847 Additional Search Info for search in Generic Frontend Server.
2849 Fixed CCL parsing of "field=s".
2851 WIN32 installer - using the excellent NSIS software from nullsoft.
2853 Fixed CCL parsing of "field = - <number>".
2855 Added function yaz_marc_decode that decodes MARC for line mode
2856 display or XML (similar to that used by JZKit).
2858 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2859 Z39.50. But ISO/ILL was, however.
2861 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2862 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2864 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2865 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2867 --- 1.8.5 2002/02/03
2869 New YAZ client features: Command completion and new commands:
2870 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2871 Code provided by Jacob Poulsen.
2873 New call oid_trav, that visits all registered OIDs via callback.
2875 Function ZOOM_record_get now returns const char pointer rather than
2876 void pointer. It saves a lot of type casts.
2878 For YAZ client, command "auth" now allows you to set authentication
2879 in IdPass style. It is enabled when three tokens are given - order
2880 is user, group and password.
2882 Fix memory leaks in MARC record handling for ZOOM.
2884 New option for YAZ client, -k <kilobytes> that sets
2885 maximum record size. Similar to -k option for generic frontend
2886 server and yaz-ztest.
2888 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2890 Prefix query parser reports "fail" when bad attribute set is given.
2892 Fix in MARC decoder. Proximity logging. Fix for attribute set
2893 in scan handler for server. Patches by Shigeru Ishida.
2895 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2898 Configure option --with-openssl=<dir> now works when a directory is
2899 specified. Patch provided by Morten Bogeskov.
2901 New option for YAZ client, -u <auth>, that sets authentication.
2903 ZOOM fix: error information was sometimes "missing", since error
2904 was cleared/reset too when it shouldn't.
2906 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2908 --- 1.8.4 2002/01/04
2910 Scan for ZOOM API. New object ZOOM_scanset. New functions
2911 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2912 ZOOM_scanset_destroy.
2914 New ZOOM function, ZOOM_connection_last_event, that returns type
2915 of last event (such as "receive data", "send data", "apdu received",
2918 New ZOOM option, schema, that specifies schema for retrieval.
2920 New CCL feature. Qualifiers can be aliases for one or more
2921 other qualifiers (if more than one is given, OR is used).
2923 ZOOM uses named result sets if target supports it.
2925 Two new YAZ client commands: . (dot, which sources a script of YAZ
2926 client commands), and ! (to execute shell command.). Implemented
2929 Working on Debian packages.
2931 --- 1.8.3 2001/11/19
2933 YAZ client enables named result sets only if target supports it.
2935 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2937 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2938 with key="host" to get same result.
2940 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2941 Function Z3950_resultset_record(s) returns references to records
2942 "owned" by resultset. To become owner use Z3950_record_clone.
2944 Function z_ext_record handles Extended Services. Thanks to
2947 --- 1.8.2 2001/11/12
2949 CCL Parser fix: ignore token comma when dealing with and-lists.
2951 Documentation updates for COMSTACK.
2953 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2954 Changed prototype Z3950_records. For some functions, int parameters
2955 were changed to size_t.
2957 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2960 New MARC decode/display function, marc_display_exl, which properly rejects
2961 non-ISO2709 records. YAZ client uses it.
2963 --- 1.8.1 2001/10/29
2965 Fix bug: local attribute set wasn't set correctly in PQF strings.
2969 * Old Z39.50 codecs no longer supported.
2971 Added ZOOM C binding. See http://zoom.z3950.org/
2973 Renamed states for COMSTACKs to avoid confusion with events.
2975 Implemented cs_look and proper cs_rcvconnect.
2977 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2979 Configure detects POSIX threads on OpenBSD.
2981 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2982 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2984 When error is returned from present handler, non-surrogate diagnostic
2985 is returned in present response (and fetch handler is no longer called).
2987 * Minor adjustments to pquery parser (PQF). Token characters may be
2988 escaped by using backslash (C-style).
2990 PQF parser allows string attribute values to be specified. For @attr,
2991 non-numeric characters after the equal-sign are treated as strings
2992 (e.g. @attr 9=title).
2994 CCL trunction character may be defined (@truncation in file)
2996 * function zget_ExtendedServicesRequest sets waitAction to
2997 waitIfPossible (was wait).
2999 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3002 CCL operator names may be set in field definition files (CCL_bibset).
3003 See ccl/bib1 for an example.
3005 Fixes in ASN.1 compiler for C++ compatibility.
3007 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3008 and "op_or" to avoid conflict with C++.
3010 Fixed problem with GNU readline detection on Redhat 7.0.
3012 Added step-size for Scan backend handler.
3014 Fixed bug that made the frontend server crash when no attribute
3015 set was specified for scan.
3017 Front-end server automatically switches to original working directory
3018 when installed as an NT service. Previously -w had to be specified to
3021 Added extended attributes for retrieval module (data1), so that data1
3022 records carry d1_readXML/SGML attributes. d1_read also supports
3023 null-data rules ( <tag/>)
3025 On UNIX when POSIX threads are available, a separate library libyazthread
3026 is created. Programmers should link with that library and the yaz library
3027 when using threads. The reason for the split was that some applications
3028 on Linux, such as Apache, doesn't work well when using shared objects that
3031 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3032 (or any frontend server) in SSL mode by specifying ssl: followed by
3033 address. Only tested on UNIX.
3035 Added feature for CCL module. Virtual structure s=al or s=ol generates
3036 and-list and or-list respectively instead of phrase search.
3040 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3041 log_mask_str. This was done to avoid name conflicts with other libraries
3042 (such as other PHP extensions).
3044 Added raw OID member for preferred record syntax (request_format_raw)
3045 and returned record syntax (output_format_raw) for backend fetch method.
3047 Config file yaz-config now accepts options so that it returns specific
3048 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3050 Shared library support for UNIX using GNU libtool.
3052 * Modified backend interface. Request/Response struct's replaced by
3053 one read/write C struct. For example bend_fetchrequest and
3054 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3055 Every handler - even search has to be registered in bend_init
3056 handler. This means that the YAZ library no longer refers to
3057 external functions and it makes it possible to make the whole
3058 thing a single DLL/SO.
3060 Added Segment handler for backend server.
3062 Added Zmbol/Zebra administrative functions to YAZ client.
3064 Threaded frontend server on UNIX (when POSIX Threads are available).
3065 Starting the server with option -T enables multi-threading.
3069 Added configure option --enable-comp/disable-comp to control use
3070 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3071 located in sub directory asn.
3073 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3074 in ${exec_prefix}/bin along with the other programs yaz-client and
3077 GNU automake used to maintain makefiles.
3079 Added several OID's.
3081 Changed retrieval module so that we can load records with no abstract
3082 syntax defined. Tagpaths in these records are fully composed of string
3085 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3089 On UNIX, the generated makefile now supports a proper 'make install'.
3090 The prefix can be set via GNU configure to set the install location
3091 (default is /usr/local).
3093 * YAZ programs client and ztest were renamed to yaz-client and
3094 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3095 locations, such as /usr/bin,/usr/local/bin,etc.
3097 * YAZ Header files were moved from include to include/yaz. YAZ Header
3098 files are referred to as include <yaz/log.h> rather than <log.h>.
3099 The YAZ include path (-I ..) is therefore the same as before. Programmers
3100 should update their #include statements or use -Ipath/include/yaz
3101 instead. The main motivation for doing this change is that YAZ header files
3102 can be installed in "standard" locations /usr/include,/usr/local/include
3103 without introducing conflicts, since ALL YAZ header files are stored
3104 in subdirectory yaz (under /usr/include for example).
3106 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3107 rather than project/workspace files. We switched because project files
3108 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3111 Changed name of logging function, logf, to yaz_log, to prevent name
3112 clash with some math-log functions. The YAZ header log.h defines logf
3113 to yaz_log (#define) so there should be no incompatibilities by this
3116 Added bend_start/bend_stop handlers for server. These handler are
3117 called on start/stop of server. For windows they are called whenever
3118 a service is started/stopped.
3120 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3121 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3122 in util/yc.tcl. The auto-generated C code structures are, in a few
3123 cases, incompatible with the old decoders. There are differences in the
3124 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3125 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3126 The preprocessor variable ASN_COMPILED is defined when the compiled
3127 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3128 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3129 wish to use the old encoders/decoders you can specify --disable-yc
3132 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3133 version so that it supports both new - and old version of DB Update
3135 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3136 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3137 change. The name parameter can be set to 0 in which no name is specified
3138 for the construction. The macros odr_implicit and odr_explicit sets name
3139 parameter to zero for the construction involved. New macros
3140 odr_implicit_tag and odr_explicit_tag are similar to the others,
3141 except that a name parameter is added. For programmers' that don't use
3142 ODR they probably only need to change the call to z_APDU and z_External.
3144 Added access control facility by interfacing the TCP wrapper library.
3145 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3146 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3147 name of the daemon and enables the access control as specified in
3148 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3150 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3151 den Dool <H.M.vdnDool@kub.nl>.
3153 Added reference ID parameter to most functions in server API - refer
3154 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3156 Changed name of ccl library to libccl.a (was ccl.a).
3158 Fixed bug in decoder for Explain (Category TargetInfo).
3160 Added support for GNU readline in client. Thanks to Jacob Poulsen
3161 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3163 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3164 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3165 IMPLEMENTATION! This change was made to the development version before
3166 the ZIG decided to retract the amendment. If any users MUST be
3167 compatible with the original Update definition, PLEASE CONTACT US, and
3168 we will include a separate definition corresponding to the old Update
3169 ES. Note that because of the change to the ASN.1 of the
3170 TaskPackageRecordStructure we cannot define a single structure that
3171 will support both versions.
3173 * Added const modifier to buffer parameter for some ODR/BER encoding
3174 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3175 completeWAIS, odr_dumpBER.
3177 Fixed bug in client.c which caused a crash when a scanResponse didn't
3178 contain positionOfTerm.
3180 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3181 * will cause an error in a client if a non-YAZ target sends both a
3182 * list of Scan entries and non-surrogate diagnostics.
3184 Retrieval module enhancements. Tag sets may be typed in the reference
3185 to it. From the .abs-file the "tagset" directive takes a third optional
3186 integer type for the tag set referenced. From a .tag-file the "include"
3187 directive takes a third optional type as well. The old "type" directive
3188 in the tag set itself is still recognized but acts as the default type
3191 Backend interface change. Individual Scan terms returned from bend_scan
3192 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3193 in include/backend.h.
3195 Retrieval module enhancements. Multiple tag sets and attribute sets may
3196 be specified in abstract syntax specs. Revised the error/warning for
3197 logging messages reported by the retrieval module when reading the
3200 Object Identifier system (oid_..) changed. The API is backwards
3201 compatible but the oid-routines now allocates new OID's when needed.
3202 Raw OID's may be specified in oid_getvalbyname.
3204 YAZ now uses GNU configure to generate Makefile(s).
3206 * Minor changes in some of the member names of DeleteResultSetRequest and
3207 DeleteResultSetResponse. See include/proto.h.
3209 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3210 and added member 'languages' in TargetInfo (which was missing).
3212 Changed the way attribute sets are handled in the retrieval
3213 module. These are now cached, just like the abstract syntaxes
3216 Changed YAZ so that it links with compiled ASN.1.
3218 Added Explain-schema definitions and mapping routines. The following
3219 Explain categories have been implemented: AttributeDetails,
3220 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3222 Fixed minor bug in Windows version of Server Library.
3224 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3226 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3228 Added EXTERNAL: UNIverse Resource Report (non-standard).
3230 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3231 ENUMERATED and SET OF.
3233 * Added 'const' to some of the char pointer arguments for the
3234 functions, data1_read_node, data1_getelementbytagname,
3235 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3238 Fixed bug in data1_insert_taggeddata - the last_child member of
3239 parent wasn't initialised.
3241 * Changed data1_read_record and data1_read_node so that the supplied
3242 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3243 doesn't refer to any parts of the "SGML"-buffer.
3245 Fixed bug in server library (Windows version of statserv_remove).
3247 * Changed code so that it compiles as C++. The type definition
3248 of Odr_fun which is a member of Odr_arm was changed. The result is,
3249 that an explicit typecast is needed for the fun pointer when
3250 using Odr_arm - as in:
3251 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3253 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3255 Implemented the new structured date and time definition as approved
3256 by the ZIG. Added schemaId element to the specificTag in Espec-1
3257 (also approved at the last ZIG). Thanks to RVDM.
3259 Added some Object identifiers (RVDM).
3261 Changed the Update Extended Service (RVDM).
3263 Added command "refid" to client which specifies referenceId for
3264 the following requests.
3266 Implemented extended service handling for server. See ztest.c
3267 for an example as well as backend.h. New handlers are registerd
3268 in the Init handler.
3270 * Changed interface for sort in server.
3272 Added new members to statserv_options_block. It allows a server
3273 to read options from another source than just the command line. Thanks
3274 to Charles Woodfield.
3276 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3277 renamed to zboolean. Some C++ compilers complained about the name.
3279 Minor changes to gils.abs. Added index 's' (sort) on title
3280 and date/time-last-modified.
3282 --- 1.4pl2 1998/1/30
3284 Fixed bug in server library regarding inetd mode (-i). This bug
3285 was introduced by release 1.4.
3287 --- 1.4pl1 1998/1/29
3289 Added sort facility in client and backend server interface.
3291 Fixed problem with dependencies in Makefile(s).
3293 Fixed bugs for encoders/decoders of extended services and
3296 Implemented sub-tree feature for schemas. Sub-trees are
3297 referenced in *.abs-files. See explain.abs for an example
3298 of the use of this feature.
3300 Modified bib1.att; local attributes for ANY didn't include
3301 ANY itself (only affects use of the retrieval module).
3303 Fixed bug in plain SGML reader in function data1_read_node:
3304 tags with prefix "var" was incorrectly interpreted as variants.
3306 Added feature "sub-schemas" to enable references to - and definitions
3307 of - group of elements.
3309 * Removed member parent from type data1_element (in data1.h).
3311 Implemented function odr_nullval() that returns the value of
3314 * Removed member num_children from data1_node (in data1.h).
3316 Made NT service interface part of the server library. The
3317 function statserv_main uses the NT service when required and
3318 calls the statserv_start / statserv_close routines.
3320 Routine zget_SearchRequest and zget_PresentRequest fills
3321 resultSetName/Id member with "default" instead of "Default".
3323 Fixed memory leak in server. Request queue member wasn't freed.
3325 Fixed nmem_exit so that memory is freed.
3329 Revised the CCL parser utility to be thread safe.
3331 Added function, oid_ent_to_oid, to replace the function
3332 oid_getoidbyent, which is not thread safe.
3334 * Added nmem_init and nmem_exit to initialize and release
3335 NMEM resources. Function nmem_init should be called once in the
3336 initial thread before NMEM/ODR is used. statserv.c and client.c
3337 have been changed accordingly. The change was necessary to make
3338 NMEM thread safe. The NMEM memory pool is shared amongst threads
3339 in a process. Unix-based applications will still work fine without
3342 Added NT Services interface for the the Z39.50 (statserv) Server.
3343 Refer to the ztest.c source on the usage.
3345 Windows 95/NT port using MSVC5.0. Project files are included in the
3348 * Defined new 'global' handle for the retrieval (data1) system. The
3349 new handled, data1_handle, describes the state of the data1 system.
3350 This handle is passed as first argument to virtually all
3351 data1 related routines. The functions data1_create and data1_destroy
3352 creates and destroys a data1 handle respectively.
3354 Added ODR encode stream member to all backend request structures
3355 init, search, scan etc. This stream should be used to allocate all
3356 memory used for the response when thread safe operation is needed.
3358 Changed the comstack utility, cs_addstr, to be thread safe. The
3359 returned hostname string returned by the function is now part the
3362 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3363 function. The cs_straddr takes a COMSTACK handle as argument, so this
3364 function must be used after cs_create and before bind/connect.
3365 This function is thread safe.
3367 Moved test server to 'ztest' directory - generic server code still
3368 in 'server' directory.
3370 Made prefix query (pquery.c) utility thread safe.
3372 Added new function modifier YAZ_EXPORT to 'export' public DLL
3373 functions when using windows (see include/yconfig.h).
3375 Added definitions to the OID database (util/oid.c) (RVDM).
3377 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3379 Added call to ccl_rpn_delete in client program.
3381 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3382 release of RPN structure.
3384 Added support for C++, headers uses extern "C" for public definitions.
3385 With input from RVDM.
3387 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3388 Thanks to Ronald van der Meer (RVDM).
3390 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3392 Added support for private extensions to the OID database
3393 (oid_setprivateoids()). Thanks to RVDM.
3395 Added optional, physical ANY (key replication)
3397 Fixed null-reference problem in GRS-1 output filter.
3399 Proximity operator added to Prefix Query Format (PQF).
3401 In test client command "base" accepts multiple databases.
3403 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3407 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3409 Smallish bug-fixes in the new encoders/decoders (explain).
3411 Bug fixed in DeleteRequest.
3413 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3415 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3417 Added SOIF syntax (using private OID for now) to retrieval module and client.
3419 Added Update extended service.
3421 Added SearchResult-1 additional info structure.
3423 Added optional CCL (ISO8777) interpreter as separate module. Available
3426 --- 1.2 1996/6/10 (1st anniversary release)
3428 Added Summary record syntax. Lightly tested.
3430 Added OPAC record syntax. Untested.
3432 Added ResourceReport service encoders/decoders. Untested.
3434 Fixed bug in z_Unit - wrong tagging on unitSystem.
3436 Fixed bug in the DiagRecs decoder.
3438 Added options for max PDU size and session timeout to frontend-server.
3440 Added documentation of query-language parsers and other supporting utilities.
3442 [frontend-server] Added Attribute set to the bend_scanrequest API.
3444 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3445 surrogate diagnostics were generated.
3447 [retrieval] Allow multiple local values for attribute.
3449 [retrieval] Allow multiple attributes per element in .abs files. index type.
3451 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3453 --- 1.1pl2 1996/4/10
3455 Minor changes, mostly specific to Zebra's requirements (retrieval)
3459 Repaired bug in frontend server when running multiple listening
3460 endpoints in dynamic mode.
3462 z_External() now won't break if a known, ASN.1 value comes encapsulated
3463 in an octet-string. The value will pass through unmodified in an Odr_oct.
3465 Added a bit of code to the demo client to decode & display
3466 ASN.1-structured records represented in the octet-aligned branch of
3467 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3469 Added z_ext_getentbyref() to the ASN module. Doc updated.
3471 * Completed the SCAN definition in the ASN module. This may break SCAN
3472 code based on older YAZ-versions at compile-time. The fix is easy -
3475 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3476 under the SCAN definition. Remember to initialize this, server-people.
3478 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3479 that this does not extend to ODR and ASN.
3481 Comstack allows insertion of established socket (primarily for
3482 inetd-operation of servers). Doc updated.
3484 Front-end server can now start from the inetd in TCP mode. Doc
3487 --- 1.0pl4 1996/1/24
3491 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3492 the rank and record number.
3494 Adjustments to the frontend server.
3496 Fixed diagnostic BER dumper. It ignored the file argument.
3500 Various changes to retrieval module.
3502 Changed the union discriminators of the protocol files from enums to
3503 ints paired with #defines.
3505 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3508 *Changed operator in the RPN structure to 'roperator', again to avoid a
3511 Fixed problems in Explain decoders/encoders.
3513 --- 1.0pl2 1995/12/6
3515 Memory bug in log module fixed.
3517 --- 1.0pl1 1995/12/5
3519 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3521 Bug in Explain DatabaseInfo module fixed.
3523 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3527 The shift to v1.0 signals that we now consider the *core* functionality
3528 of YAZ reasonably stable (the core being more or less equivalent to
3529 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3530 tested (Explain not at all - though that will happen soonish).
3532 Minor changes to code to support Windows port.
3534 Various minor changes after we're getting to use GRS-1 & co. more.
3536 Added Espec-1 format.
3538 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3539 of the protocol and it cannot be selected when encoding (maps into 'string'
3540 when decoding). Needed to talk to some servers.
3542 Demo client can request simple element set names.
3544 Added Diagnostic Format encoders/decoders.
3546 Added simple Close handling to frontend server (no hooks for resource
3547 reporting yet), and demonstration client.
3549 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3551 --- 1.0b3 1995/08/24
3553 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3554 handled incorrectly when records were requested in the searchResponse. This
3555 will only affect you if you use the frontend-server.
3557 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3558 Test-client will ask for and print GRS1. Ztest will return dummy records
3561 Added Explain encoders/decoders to the service-level API. Untested.
3563 Added Extended Services: Item Order encoders and decoders to the Service-
3564 level API. Untested. We could use a recent copy of the pertinent bits
3565 of the ILL protocol to add those bits.
3567 Added diagnostic format 1 encoders/decoders to the service-level API.
3570 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3571 odr_cons.c, which causes a more correct output.
3573 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3574 was always set to 0 when no records were requested in the searchRequest.
3576 * Added better external-handling. This shouldn't harm old code that
3577 *encodes* externals. It can break code that looks for a
3578 'single-ASN1-type' representation, since those types that are known
3579 are now decoded immediately. Look at the SUTRS sample code in
3580 seshigh.c and client.c. Documentation updated.
3582 Handling of structured records in bend_fetchresponse. Length -1 marks
3583 structured record, type is deduced from format field.
3585 --- 1.0b2 1995/06/27
3586 Fairly quick maintenance release to add SUTRS support.
3588 Fixed handling of SUTRS records in the demonstration client.
3590 * Added format field to the bend_fetchrequest and bend_fetchresponce
3591 structures of the backend API (frontend server). When the record is
3592 returned, the value of the format field is mapped to an OID. The
3593 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3594 of the record. The special value VAL_NONE in the bend_request means
3595 that no specific format was requested by the client. Documentation
3596 updated accordingly. Test server (ztest) will return a fixed dummy
3597 SUTRS record if your client requests SUTRS.
3599 Documentation updated accordingly.
3601 You can now set external libraries and RANLIB support in the top-level
3605 First public release.
