3 ICU: fix bug in icu_iter_get_org_info (un-init variable).
7 Implement z_HTTP_header_remove.
11 ICU: Disallow 0 ptrs for some ICU string utilities.
13 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
14 returns original tokens (before normalization).
16 CCL: avoid z39.58/regex truncation when not needed. Apply only the
17 conversion of those masks, when absolutely necessary.
19 CCL: configurable masking character - @mask. Default masking character
22 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
23 full response anyway, so a Transfer-Encoding header will obstruct the
28 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
29 picking a socket. Problem is that some systems has IPV6 support, but
30 we can't create sockets for them, so we pick AF_UNSPEC first.
32 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
33 use content_len to determine resulting Content-Length in HTTP response
34 and NOT Content-Length supplied in headers by user.
36 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
37 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
39 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
42 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
43 with big endian and unsigned char (by default).
47 Fix yaz-client connect (crash in 4.2.55).
51 Fix proxy/host problem for ZOOM that could occur if unix sockets
54 New Debian package libyaz4-dbg.
56 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
57 differently in tcpip_close.
61 Windows installer of YAZ includes YAZ4J as a component.
63 CQL: allow "extra terms" again, by default. Thus, the CQL parser
64 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
65 and earlier. CQL parser may operate in strict mode where queries
66 not conforming to the standard BNF are rejected (syntax error).
67 Whether the CQL parser operates in strict mode is controlled with
68 cql_parser_strict . Strict mode enabled with option -S for utilities
69 cql2pqf and cql2xcql .
71 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
75 New charset, MARC-8c, which is like MARC-8 but allows control characters
76 0x01 through 0x1F, except ESC to be passed through verbatim.
78 Fix a problem with duplicate sub field character in MARC output. Problem
79 happened only when output was MARC-8 encoded.
83 yaz-ztest: Use hash for fake hit count. Before, random number was used.
84 This is problematic for unit tests using yaz-ztest. This patch also makes
85 a hash for CQL queries. For RPN, any term with a leading digit will be
86 treated as pseudu hit count (to force any particular hit count by a client).
88 yaz-ztest: return unique MARC dummy records. Beyond record offset
89 24, the author surname is patched with offset to make all records
92 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
93 on system wide default (/proc/sys/net/ipv6/bindv6only).
94 @4 binds to IPV4 only. @6 binds to IPV6 only.
96 Update CQL API documentation a bit
98 CQL: don't accept extra terms for queries. Makes the CQL parser
99 stricly conformant to the standard.
101 --- 4.2.51 2013/02/12
103 GFS: scan handler gets extra_args from request and may return extra
104 response data . That's for SRU only.
106 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
108 --- 4.2.50 2013/01/30
110 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
112 OPACXML: sync spelling of availabilityDate in XML to that of Schema
113 opaxxml.xsd. The schema had the correct spelling of this member always.
114 The ASN.1 was mis-spelled and still is (API change) - we are
115 not changing this. However, the OPAC to XML conversion had yet
118 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
121 New function, z_ext_record_oid_nmem, which is similar to
122 z_ext_record_oid but takes NMEM rather than ODR
124 --- 4.2.49 2013/01/18
126 ICU: New conversion element 'join' which joins tokens into one
127 with a custom character given by rule attribute.
129 --- 4.2.48 2013/01/10
131 New GFS search member: present_number. This is a hint to the
132 search handler how many records are going to be fetched immediately
133 following search. There's no guarantee that it's going to be the case,
134 since it depends on hit count (for Z39.50 piggyback) and whether errors
137 Make a few functions static (private). The functions getbyte_stream,
138 ungetbyte_stream and yaz_gets are now private. They were never declared
141 yaz-marcdump: exit(5) for serious decoding errors
143 ISO2709 decoding: be more picky WRT header
145 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
146 was only used as to indicate that next-result-set-position should be
148 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
149 Based on patch from Ashley Sanders.
151 Make some functions static/private in PQF parsing. Those functions were
152 never declared in a public header and so should not be in use by
153 applications based on YAZ.
155 --- 4.2.47 2012/11/23
157 ZOOM: special options to control APDU logging.
158 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
159 logging of APDUs until "saveAPDU" option is set again. If logging is
160 already enabled the effect is that current APDU buffer is cleared.
161 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
162 logging (default behavior on new connection).
163 The APDUs sent/received can be obtained by using
164 Using ZOOM_connection_option_get(c, "APDU") or
165 ZOOM_connection_option_getl(c, "APDU", &l).
167 GFS: relay implementation_version from backend
168 From 3.0.40 and later, implementation_version from backend was
169 not used in init response at all.
171 --- 4.2.46 2012/11/15
173 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
174 mode at all. Probably never did.
176 Make a new version of ztest.pem that, at least, is not expired.
178 --- 4.2.45 2012/11/13
180 Fix description of CCL directive 'case'.
182 More tight checking of form arguments (yaz_uri_to_array). Makes
183 YAZ better at rejecting big and/or bad POSTs.
185 SRU decoding does not report more than up to 10 invalid arguments.
187 rpn2cql: less quotes in generated terms. Semantics unchanged, but
188 it's prettier this way.
190 --- 4.2.44 2012/10/25
192 New utility yaz_decode_init_diag. Defined in proto.h.
194 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
195 given for unix local socket.
196 The COMSTACK string for doing so is:
199 unix:/myfile:tcp:localhost:9999/mybase
200 unix:/myfile:localhost:9999/mybase
201 unix:/myfile:http://fakehost/mybase
203 debian: Use dpkg-buildflags in build process.
205 --- 4.2.43 2012/10/19
207 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
208 global's SRU service uses a recordPosition scheme starting from zero.
209 First record's position should be one
210 according to the standard.
212 --- 4.2.42 2012/10/18
214 Allow more namespaces for SRU. This is to allow, for example, an
215 incorrect namespace returned from server
216 http://services.igi-global.com/sru .
218 Minor fixes for compilation on Windows.
220 --- 4.2.41 2012/10/11
222 daemon: log total number of bad signals from child on stop so that it
223 is more easy to spot problems with child worker processes.
225 retrieval: empty backend name attribute omits element set
226 from being used in retrieval.
228 --- 4.2.40 2012/10/04
230 Implement Solr sort strategy "solr", similar to sru11 sorting.
231 This will implement the correct parameters on Solr requst to do
234 --- 4.2.39 2012/09/28
236 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
239 MARC: Extra/missing indicator handled for MARCXML.
240 The indicator length is given in header and is the same for the
241 whole record. If attributes ind1, ind2 are missing, then content
242 character defaults to blank. Extra indicator attributes (beyond)
243 indicator length are treated as an error.
245 Reformat: delete trailing whitespace
247 --- 4.2.38 2012/09/17
249 MARC: fix non-ASCII characters for leader. This is to ensure we can
250 generate XML in UTF-8.
252 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
253 in one node with structure word.
255 --- 4.2.37 2012/09/04
257 yaz-json-parse: JSON output may be pretty printed by using option
260 Increase default value of max message for Z39.50 Init for GFS, ZOOM
261 and yaz-client. Old value was 1 MB. New value is 64 MB.
263 --- 4.2.36 2012/08/22
265 yaz-client: don't display bogus records from SRU servers. Some SRU servers
266 return more records than given by *maximumRecords*. Skipping those in
269 record_render: simplify buffer return handling and fix at least one bad
270 memory reference, that broke the test_embed_record sometimes.
272 Allow http://user:pass@host notation for yaz_url_exec.
274 zoomsh: allow shell command to be executed. Via the system(3) call.
276 yaz_poll: Allow num_fds == 0
278 yaz-client: fix bad encoding of "itemorder item". The itemorder
279 item <no> - command forgot to use length of encoded Item Request
280 package. Error present since YAZ 3.
282 yaz-ztest: fix bad usage of session handle. Bug was introduced when
283 result sets were saved (271a9c83).
285 SRU recordPacking: guess record packing in response rather than looking
286 at the recordPacking element which, OF COURSE, changed semantics in SRU
289 Decode SRU 2.0 responses. The official namespace for responses, according
290 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
291 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
292 nature.com's server, however, usee namespace
293 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
294 we are now using a glob-expr to match up the namespace. ZOOM C and
295 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
296 I can not find a single real example showing the "real" namespace in
297 the documentation from OASIS. The namespace for requests is different
298 from responses, but this is not added to YAZ yet, when we don't encode
301 --- 4.2.35 2012/06/26
303 zoom/record_render: add support for Base64 decoding fo MARC records
304 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
305 which will decode base64 + ISO2709 marc-8 encoded material from text node
308 --- 4.2.34 2012/06/07
310 Add missing definitions ZOOM_resultset_get_facet_field_by_index
311 and ZOOM_resultset_facets_names.
313 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
316 Change APDU dump printing to avoid long leading blanks. For levels 16
317 or larger the level is shown and the indentation is truncated but
318 recursed with modula 8. This makes it still reasonable easy to read
319 - even for nested BER dumps.
321 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
322 return 0 (incomplete package) in case where the BER package was
323 considered too nested (return value of -2).
325 dumpber: lines of level 15 are not indented further. Two spaces per
326 indentation; indentation 15 or more is indented to a fixed indentation
327 and augmented with a level=<no> indication.
329 zoomsh: increase max size of command+args
331 GFS: No limit in RPN buf size in CQL to RPN conversion.
333 --- 4.2.33 2012/05/09
335 New function for daemon utility, yaz_daemon_stop .
337 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
339 --- 4.2.32 2012/04/25
341 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
342 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
344 --- 4.2.31 2012/04/23
346 YAZ daemon utility relays SIGUSR1 to child process.
348 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
349 would result in en empty database list - which in turn would result in
350 encoding failure for search.
352 Fix reading beyond string in yaz_sort_spec.
354 --- 4.2.30 2012/04/11
356 Add two new SRU diagnostics:
357 236: Access to specified database denied
358 1015: Init/AC: Maximum number of simultaneous sessions for Userid
360 Document the very useful ZOOM-C option "apdulog".
362 CQL to RPN: term may be passed through verbatim. This is enabled with
363 truncation.cql . The assumption being that the term is already CQL.
365 --- 4.2.29 2012/03/20
367 record_conv: leader spec may be given for marc element.
368 The leader spec is given as attribute leaderspec for element marc.
369 For example to convert a MARC21 record from MARC-8 to UTF-8:
370 <marc inputformat="marc" outputformat="marc"
371 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
373 record_conv: allow user-XSLT params. For example:
374 <xslt stylesheet="MARC21slim2DC.xsl">
375 <param name="myparameter" value="myvalue"/>
376 <param name="otherparameter" value="othervalue"/>
379 record_conv: fix error handling for missing marc charsets.
381 CQL: fix extra terms in wrong order.
383 --- 4.2.28 2012/03/06
385 record_conv: modify new API for conversion types. The conversion types
386 may be passed in new functions yaz_record_conv_configure_t and
387 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
389 Avoid mixed statement/variable declare; fixes compilation with Visual
392 --- 4.2.27 2012/02/28
394 Add non-standard SRU diagnostic: 235: "Database does not exist".
395 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
396 Update SRU to Bib-1 diagnostic maps accordingly.
398 CCL: add two new diagnostics for unsupported masking. The new
399 diagnostics are: "Embedded truncation not supported" and
400 "Single charcacter mask not supported".
402 --- 4.2.26 2012/02/23
404 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
406 --- 4.2.25 2012/01/11
408 Build YAZ for Ubuntu Oneiric.
410 CCL: allow parantheses for proximity operands. For example CCL query
411 (a) % (b) is now allowed.
413 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
414 marked dead, rather then being destroyed. If not, the session memory is
415 being free'd before the search/scan handler is finished. Also destroy
416 'request' memory in request_release rather than in various places,
417 which resulted in leaks from time to time.
419 --- 4.2.24 2011/12/21
421 cql_sortby_to_sortkeys: honor sort prefix.
423 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
424 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
425 The rpn2cql family of functions now always returns quoted CQL terms.
427 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
429 --- 4.2.23 2011/12/15
431 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
432 sequence is treated as one. For example, &&a=b&&&c& is identical to
435 --- 4.2.22 2011/12/05
437 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
438 APDUs for a connection to a WRBUF.
440 --- 4.2.21 2011/11/23
442 Fix cql_sortby_to_sortkeys. Completely broken before.
444 Make CCL's @truncation work again.
446 --- 4.2.20 2011/11/09
448 New ZOOM connection setting: tproxy. It's like proxy, but does not
449 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
450 to set resolved address + port for a connection outside ZOOM itself.
452 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
454 --- 4.2.19 2011/11/07
456 Fix uninitialized variable in Solr spell support (could cause SEGV
457 for SRU response decoding).
459 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
460 back-end's addinfo through into the ZOOM response addinfo.
462 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
463 they are separated by a colon and a space rather than simply
466 --- 4.2.18 2011/10/28
468 Add support for Solr spell-checking/suggestions through ZOOM.
469 If a Solr target has been configured correctly for spelling-checking
470 and suggestions, these will now be returned on the ResultSet option
471 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
473 --- 4.2.17 2011/09/28
475 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
476 with a flag whether to substitute escape sequences or not.
478 --- 4.2.16 2011/09/22
480 Fix nmem_strsplit_escape to substitute escape char properly.
482 New option for zoomsh -e , which makes it abort on first error and
483 return process exit code to indicate success/failure.
485 YAZ options utility supports special option -- which makes all it treat
486 all following arguments as non-options.
488 --- 4.2.15 2011/09/16
490 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
491 searched if absolute filename is given.
493 Fix conv_xslt() error-reporting when stylesheet is not found.
494 (The value of fullpath is meaningless in this situation.)
496 --- 4.2.14 2011/09/07
498 Fix problem in CQL sort node creation: un-initialized memory.
500 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
501 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
502 CQL sortby depending on whether Type-1 or CQL is actually sent to the
505 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
506 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
508 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
509 will make it possible to use both single-character mask (#) and wildcard (?)
510 in CCL . Throw diagnostic for left truncation because that is not supported
513 --- 4.2.13 2011/09/01
515 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
516 cases using escapes (\-sequences) and masking.
518 PQF parse fix: A trailing backslash followed by end-of-string (\0)
519 would result in a read one byte beyond string.
521 rpn2ccl may use Z39.50 masking for terms (t=z).
523 ICU check fix. Don't include library -lCrun on Solaris, unless present.
525 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
526 not --cppflags (which seeems like an error in icu-config).
528 --- 4.2.12 2011/08/27 RPM package only
530 cql2ccl: fix conversion of terms: operator characters were not
533 --- 4.2.11 2011/08/25 RPM package only
535 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
536 CCL parser will map both # and ? to their regular expression
537 quivalents (. and .*).
539 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
540 of reserved CQL characters.
542 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
543 is, so that they are passed through.
545 --- 4.2.10 2011/08/24
547 ZOOM SRU mode: more aggressive re-connect.
549 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
550 made available as a utility function, declared in <yaz/logrpn.h>
552 rpn2cql_structure() supports proximity nodes (except that the Type-1
553 proximity node's "exclusion" binary is ignored, as there is no way to
554 express that in CQL). Fixes bug #4564.
558 Fix SEGV that could occur if set command of zoomsh was given without
559 value (2nd argument).
561 Fix SEGV that could occur if unsupported transport was given for
562 COMSTACK - say https (when SSL was unavailable).
564 Build yaz-url on Windows too.
568 New utility to get web content. Header is url.h. A command line tool
569 yaz-url is part of the distribution and packages.
571 Fixes for SSL COMSTACK (when gnutls is in use).
573 New functions yaz_base64{encode,decode}. Header is base64.h.
577 ZOOM C includes HTTP response buffer as additional info if it fails
578 to decode the SRU response.
580 Make wrbuf_json_puts available.
584 zoom: throw diagnostic for invalid value for option "sru". Before a
585 bad SRU request was sent.
587 Adding new utility wrbuf_vp_puts.
589 Add cclxmlconfig.obj to win/makefile. It was missing completely.
593 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
594 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
595 redirect was used at the same time.
597 MARC line mode decoding: be less picky about length given - first
598 5 digits of header that is.
600 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
602 Changes to decoding of SRU records: a record with recordPacking=xml is
603 modified with a new root element <yaz_record> if the recordData contains
604 multiple children elements. This is to make the record XML parseable
607 RPN to Solr conversion: encode special characters.
609 Generic Frontend Server: fix uinitialized member, stepSize.
613 Fix a bug in SRU decoding of records.. The database records stored
614 had un-initialized memory, but it would only be seen with yaz_record_render
615 and type_spec="ext" .
617 Fix a bug in ccl_qual_dup introduced in 4.2.3.
621 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
625 Add new utilities to convert from CQL to CCL . These utilities have
626 prefix cql_to_ccl defined in cql.h.
628 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
629 lead to memory heap corruptions when ICU utilities were in use.
633 Make compilation work without Libxml2.
635 yaz-client: remove redundant blanks in display of searchResult-1 term
640 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
641 resulting CQL node (tree) in a new node CQL_NODE_SORT.
643 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
644 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
645 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
646 Note that the CQL sortby spec is only converted when the GFS is already
647 converting from CQL to RPN (cql2rpn element).
649 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
650 specify whether to collapse delimitors or not. The existing nmem_strsplit
651 do collapse (collapse parameter = 1).
653 Windows installer: For NSIS, set InstallDir depending on x86/x64.
655 Rename internal func yaz_use_attribute_create. While non-static, this
656 function is not declared in a public header.
660 Add -lCrun when linking with ICU on Solaris.
662 More quicks character set conversions for OPAC records.
666 fix problem with record_render: records were converted (character set
667 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
671 SRU: add methods for handling DADS SRU-proxy facets.
673 Separate OPAC record character set for ZOOM_record. yaz_record_render
674 allows a character set given as charset=from/opacfrom,to where 'from' is
675 the character set of a bibliographic record, 'opacfrom' is character set
676 of OPAC record and 'to' is the target character set.
680 yaz-client: show may XML format records. Command show followed by 'format'
681 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
684 src/stemmer.c: Avoid using unnamed union. It is not supported by some
687 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
690 Update yaz.spec to operate on both SLES11 / Centos 5.5.
692 RPM: Release includes 'indexdata' name. Use indexdata in release name so
693 this package can be distinguished from other vendors.
695 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
696 as determined by configure
698 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
700 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
701 returns no error and no record, the present request is considered
702 partial (only a subset of the records could be returned by backend), and
703 so it is appropriate to set Present Status to partial-4.
707 Move yaz-config man pages to section 1.
709 More documentation about Solr.
711 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
712 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
713 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
714 peers on some Linux systems. However, in general that does not work
715 so YAZ can not rely on that to work. Debian changed behavior in this
716 respect from Debian lenny to Debian squeeze (still testing as of Oct
718 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
720 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
724 Fix yaz-config output: echo_source not set correctly by configure.
728 Solr Web Service support for yaz-client and ZOOM.
730 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
732 --- 4.0.12 2010/08/17
734 Z39.50 facet support. Facet specifications are passed for search in
735 other-information with ASN.1 as defined in facet.asn and OID
736 .10.1000.81.5 . Facets are expressed as an Attribute list as known
737 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
738 3 is limit (number of entries to get in response). yaz-ztest returns
739 dummy facets if a client asks for them.
741 --- 4.0.11 2010/07/09
743 CCL fixes: bug 2895 and bug 3539.
745 GR1-display: add comma in display - was removed by mistake in
748 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
750 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
752 --- 4.0.10 2010/06/18
754 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
755 result set from a connection. The result set will be on its own
756 thereafter; no operations on it will perform retrievals from a target.
757 Only cached copies are returned.
759 ZOOM C:fix case for HTTP servers responding with Connection:close.
760 Ensure that if there is a current task it is resumed (like fetching
761 more records in a result set) . Bug #3484.
763 PQF parser: use odr_atoi for Odr_int (not atoi)
765 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
766 values that contain any non-digits are treated as string attributes
767 (previously decoding only checked for leading character ([0-9]). PQF
768 encoding: attribute string values are not surrounded by double-quotes.
772 New utility for managing threads - thread_create.h.
774 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
775 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
776 but YAZ' implementation do.
778 Fixes for yaz_cond-functions on Windows 7.
780 DLL export more symbols.
782 zoomsh: show record do NOT render opac.
784 Remove *.la files from Debian and RPM packages.
788 Debian package libyaz-dev depends on libgnutls-dev again (was
789 removed in YAZ 4.0.6, but due to Libtool it is still needed
790 even though yaz-config do not list libgnutls libs).
792 ZOOM: Use only one WRBUF for returning string results for
793 ZOOM_resultset. Reduces memory usage for ZOOM in general.
795 ZOOM: ZOOM_connection do not use a shared pointer to
796 ZOOM_resultset after ZOOM_resultset is destructed by
797 user. Reverts to YAZ 4.0.4 behavior.
801 record-conv: fix problem with at least one XSL conversion -
802 due to probably incorrect usage of XML XSL documents.
806 Fix yaz-config for static mode and the use of SSL (gnutls).
810 Forward decl timeval struct in mutex.h and gettimeofday.h.
812 yaz-config: fix 'static' mode linking.
816 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
817 are wrappers for pthreads or Windows. For Windows these are put in
818 a separate DLL: yaz_cond4.
820 libyaz.la (whole source) is compiled with thread. If thread support
821 is enabled enabled, all source of YAZ is compiled with treading support.
822 This allows core utilities such as yaz_log to use thread facilities.
823 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
824 thread utilities. This commit moves mutex utilities (mutex.c) from
825 libyaz_server.la to libyaz.la.
827 yaz-json-parse displays leading text until error.
831 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
832 patch from Giannis Kosmas.
834 SRU: no longer URL encode SRU database. The URL for an SRU server is
835 a URL and such is alreeady encoded - at least when given with leading
836 http:// or https://. This reverts behavior to YAZ 3.0.50.
838 Support for new MARC XML notation TurboMARC which like MARCXML is a
839 complete representation of MARC/ISO2709.. This one, however, is more
840 compact and allows for faster processing with XSLT. TurboMARC can be
841 used in the marcdisp.h API, from the yaz-marcdump utility and from
844 yaz-ztest can be configured - via the database - to perform certain
845 delays when it performs operations search, present and single record
846 fetch. This allows testers to make yaz-ztest act as a real or even slow
847 Z39.50 server. Refer to the yaz-ztest man pages for details.
851 wrbuf_destroy allows NULL WRBUF passed to it.
853 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
855 Add ZOOM_connection_close.
857 No fixed size buffers for ZOOM shell - bug #3257.
859 tstodr: make it work on s390 platform.
861 New icu iterator-functions. The new icu_iter-functions makes it possible
862 to use ICU chains from many threads.
864 yaz-client: better syntax check for show command.
868 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
871 New simple local-file XML include facility which allows file glob-patterns.
872 Refer to yaz/xml_include.h.
874 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
877 ZOOM_record_get supports new parameter "format" which makes it format XML
880 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
881 JSONText in ECMA-262) is JSONValue, not JSONObject.
885 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
886 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
888 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
889 POSIX/Unix builds .so with major version 4.
891 Remove old LOG_-defines from log.h. They have been obsolete and
892 undefined by default for the last 5 years.
894 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
896 GFS: Remove socket (int *fd) from search_rr handler. The socket
897 descriptor ptr is a facility that allowed a search handler to supply
898 a socket which would serve as a callback - when search was complete.
899 This facility has now been in use for years.
901 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
902 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
903 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
904 returns 'const char *' rather than 'char *. The returned string is
905 read-only and should not be modified by applications. COMSTACK cs_close is
906 now a void function - it no longer returns int. No applications check for
907 the value and the implementations has always returned 0.
909 ZOOM: use size_t for scan hit counts and str size. Functions
910 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
911 occ (hit count) and len (string length) are now of type size_t pointer
912 rather than int pointer. This is to be able to represent large hit counts
913 and to also just to use the proper type for string length (strlen result).
915 New JSON parser. Refer to include/yaz/json.h .
917 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
918 Used to be int in some cases. Many wrbuf_-functions used to return an int
919 indicating some length.. These return values were never used. And so they
922 ODR: odr_malloc, odr_total now takes size_t for size.
924 clone_z_type: fix leak; occurred for encoding failures.
926 --- 3.0.52 2009/12/03
928 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
929 bug was introduced in 3.0.51.
931 --- 3.0.51 2009/12/02
933 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
935 tcpip comstack: fix leak for getaddrinfo.
937 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
938 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
939 Decoding of SRU "path" database is performed by private function
940 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
941 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
943 yaz-client: honor base command for SRU. Change when database setting
944 is applied for SRU and ensure it is kept when a connection is reset.
945 Change also the way errors are displayed or SRU (decoding of packages).
947 --- 3.0.50 2009/11/02
949 Add support for extra request / response data for SRU codecs and GFS.
950 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
951 for extra data response buffer and length. For the GFS, both request
952 and response data (XML) is carried in extra_args and extra_response_data
953 for the search handler. Patch by Ko van der Sloot.
955 ZOOM: For queries that cannot be converted to the specified rpnCharset,
956 ZOOM now returns a diagnostic on the client-side ('invalid query' /
957 10010). This fixes bug #2113.
959 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
960 cmdfile included a 'quit' command that would result in a memory violation.
962 --- 3.0.49 2009/10/01
964 Make a number of functions defined in xmlquery.c static. These have
965 never been declared in a public header file (yaz/xmlquery.h) and was
966 made public by mistake.
968 Improve speed of character conversions (iconv utilities). This makes
969 conversions from MARC-8 faster.
971 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
972 unless type desired is "raw". This will prevent type "xml" from
973 returning ISO2709 .. Which obviously can not be XML parsed.
975 Fix memory leak in ZOOM that would occur if option apdulog was used
976 on a re-used connection.
978 Frontend server logs HTTP requests.
980 Frontend server now sends Z39.50 close when it times out (sesssion has
981 been idle for too long). Versions 2.0.30 and earlier also sent close.
982 But due to a mistake this was disabled in all versions after that, i.e.
983 the server would just close the socket immediately.
985 yaz-client emits a better message when receiving an unrecognised
986 userInformationField.
988 Skip zero-length subfields when decoding ISO2709. This rare case happens
989 if a record has two FS characters in a sequence. Without this patch
990 there would be a reference beyond char array in using_code_len fragments
993 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
995 --- 3.0.48 2009/08/28
997 The show command offered by the zoomsh command now takes a 3d optional
998 parameter type which is what is passed to ZOOM_record. If the type
999 argument is omitted, "render" is used.
1001 RPN to CQL conv may use USE string attributes (bug #2978).
1003 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1005 --- 3.0.47 2009/07/08
1007 Function yaz_xml2query allows a diagnostic element in the PQF XML
1008 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1009 code and additional info respectively.
1011 The BER BOOLEAN is now the integral type Odr_bool which still happens
1012 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1013 typedef'd to Odr_int. This is still an integral 'int', but it may be
1014 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1015 ASN-1 compiler as well as programs has been updated to use the new types.
1017 --- 3.0.46 2009/06/08
1019 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1020 only the bibliographic record was rendered. For type=opac, an OPAC
1021 record is only returned if it is present.
1023 iconv: small fix for encoding of advancegreek.
1025 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1027 yaz-client: option auto_reconnect=on really reconnects.
1029 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1031 server: avoid null ptr ref for for yaz_poll errors.
1033 build: fix RPM build for RHEL 5.3.
1035 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1037 --- 3.0.45 2009/03/31
1039 Fixed bug #2709: TCP connect returns Invalid argument.
1041 Fixed compilation for mingw.
1043 Honor charset for raw records (ZOOM_record_get).
1045 Fixed use of errno for threaded mode that was seen on Solaris 10.
1047 Fixed argument passing with blanks in value for Windows Service.
1049 Disable YAZ' own log rotate by default (no 1 GB limit).
1050 The variable l_max_size which specifies the log file limit is set to 0
1051 (DISABLED): This is due to the fact that YAZ is most often deployed using
1052 logrotate. Also YAZ can not perform log rotate because of unsufficient
1053 permissions (setuid).
1055 --- 3.0.44 2009/02/17
1057 List supported encodings in man page for yaz-iconv.
1059 Fixed missing SSL libs for --libs output
1061 Re-established OID record syntax application-xml. Nobody should use it
1062 but we don't want to change soname because of this symbol being absent.
1064 --- 3.0.42 2009/02/02
1066 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1068 Added member named_result_sets for init handler struct for the GFS. This
1069 allows a server to disable named result sets.
1071 Removed OID record syntax application-xml.
1073 Added support for rule-based transliterator for ICU wrapper of YAZ.
1075 Fixed bug #1902: yaz-icu XML output.
1077 Make YAZ checks Emacs friendly.
1079 BITSTRING value shows value. Bug #2346.
1081 ISO2709 decoding: skip control characters from indicator data.
1083 Omit sort key by default in yaz-icu's output.
1085 Allow combined single char options (again) for YAZ' options function.
1087 Utility yaz-marcdump got option to display YAZ version (-V).
1089 Allow YAZ to use ICU 3.4.
1091 Added new ICU test case which illustrates removal of diacritics.
1093 --- 3.0.41 2008/12/29
1095 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1097 --- 3.0.40 2008/12/29
1099 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1102 Fixed bug #2352: yaz-marcdump crashes for certain record.
1104 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1106 Added support for Danmarc2 to UTF-8 conversion.
1108 Added support for ISO5426 to UTF-8 conversion.
1110 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1111 implementation version.
1113 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1115 --- 3.0.38 2008/11/10
1117 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1118 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1120 ZOOM C now interprets databaseName option for ZOOM connection as path
1123 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1125 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1127 Dummy Libxml2 types no longer defined in headers of YAZ'.
1129 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1132 --- 3.0.36 2008/09/26
1134 Various ODR chapter fixes.
1136 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1138 Added missing source for Windows compilation, mutex.c.
1140 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1142 For SRU connections in ZOOM all records up to "count" are now fetched.
1144 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1145 in Windows due to bad error handling for Libxml2.
1147 Added facility for sending arbitrary records (ASN.1 any) using
1148 ZOOM C's Extended service update. Patch by Sam Reynolds.
1150 New options for ZOOM C's connection, logapdu which makes ZOOM log
1153 --- 3.0.34 2008/06/18
1155 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1157 --- 3.0.32 2008/06/12
1159 Fixed memory violation that could occur when decoding UTF-8. This bug
1160 was only present in 3.0.30 of YAZ.
1162 --- 3.0.30 2008/06/06
1164 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1165 GNU TLS is used by default (if found).
1167 yaz-ztest returns OPAC records if a client asks for OPAC.
1169 Improved speed of MARC-8 encoding.
1171 Added support for lossy and loss-less MARC-8 encoding.
1173 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1175 Added new Windows Service wrapper (sc).
1177 yaz-client's itemorder command may now send a file.
1179 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1181 Added new function yaz_log_xml_errors.
1183 Allow (but warn) unknown XML attributes in MARCXML parsing.
1185 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1187 The UTF-8 to MARC-8 conversion now uses a different set of characters
1188 for Greek symbols. Bug #2120.
1190 --- 3.0.26 2008/02/21
1192 Added yaz_daemon (daemon.h).
1194 Fixed bug #2068: pkg-config trouble
1196 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1198 --- 3.0.24 2008/01/28
1200 Document --with-xml2 option.
1202 Added OPAC XML XSD (etc/opacxml.xsd).
1204 Allow glob mask for name attribute in retrieval element for the
1205 generic frontend server's retrieval facility.
1207 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1208 except POLLIN/POLLOUT.
1210 Fixed error handling in cs_listen. Bug #2037.
1212 --- 3.0.22 2008/01/20
1214 Fixed version in yaz/yaz-version.h.
1216 Fixed bug #2027: Crash when closing connection.
1218 Changed configure so that ICU support is only enabled if only ICU
1219 and Libxml2 is available (because the ICU chain is XML based).
1221 --- 3.0.20 2008/01/15
1223 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1224 is built. Only this DLL depends on the ICU runtime.
1226 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1227 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1229 Changed license of CCL module to 'Revised BSD'. After consultation with
1230 remaining members of the original EUROPAGATE consortium, we are re-issuing
1231 the CCL module without a separate license. The software was developed by
1232 Index Data as part of a research project. The special license was included
1233 to help feed usage information back to the project consortium to support
1234 project evaluation. At this time, the project consortium has long-since
1235 disbanded, and the majority of the original principals have retired. At the
1236 same time, we have significantly modified the software during the following
1237 years, to the point where very practically no original code remains. To
1238 simplify re-use of the software, we have contacted those members of the
1239 consortium who could be reached, and agreed to re-issue the module as a
1240 proper part of the YAZ package.
1242 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1244 CQL closer to being version 1.2 compliant. CQL also allows free-form
1245 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1248 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1249 bug could make Extended services handling crash in the ZOOM layer. This
1250 bug was only present in YAZ 3.0.18.
1252 --- 3.0.18 2007/12/19
1254 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1257 yaz-marcdump reads and writes collection wrapped records.
1259 Handle OPAC for record conversion module.
1261 Fixes for ICU wrapper.
1263 Allow ICU libs to be controlled with --with-icu .
1265 --- 3.0.16 2007/11/12
1267 Added yaz_poll which is a wrapper for select/poll. When poll is available
1268 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1269 sockets to be in use.
1271 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1272 functionality through an XML based configuration (ICU chain). This system
1273 is useful for search facilities such as Pazpar2 and Zebra that needs to
1274 perform tokenization of indexed material. The ICU code in a separate
1275 library libyaz3_icu.a.
1277 Added HTTP tunnel facility for COMSTACK, bug #1752.
1278 This is a facility that allows a Web proxy, such as squid, to tunnel
1279 Z39.50 traffic. This facility is "transparent" to must applications
1280 using YAZ. It's enabled by using pseudo transport connect: followed by
1281 the proxy address, followed by command, then follwed by he regular
1282 "virtual" addresss. For example,
1283 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1285 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1287 --- 3.0.14 2007/09/21
1289 Fixed bad memory reference in ZOOM_record - cuased by member not being
1290 initialized. This was a problem only in YAZ 3.0.12.
1292 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1293 fields were not removed.
1295 Changed the way C code is generated from codetables.xml. Made a MARC-8
1296 conversion trie for each characterSet section rather than codeTable.
1297 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1298 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1300 --- 3.0.12 2007/09/12
1302 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1303 from ZOOM_record_error).
1305 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1307 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1309 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1311 Better SRW-to-Bib-1 diagnostic mapping.
1313 ZOOM C and yaz-client announces SRU version 1.2 by default.
1315 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1318 Fixed in yaz_sru_decode to allow other version than 1.1.
1320 --- 3.0.10 2007/08/22
1322 Added support for SRU scan for ZOOM.
1324 Added support for the use of the older versions or Extended Service
1325 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1326 set to the version , 1=first, 2=second, 3=third. The third version is
1327 what ZOOM C has used so far. And that, obviously, is the default.
1329 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1330 therefore in Zebra and in SimpleServer-based applications). The new
1331 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1332 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1333 which is passed into the back-end search callback function.
1335 Added support for HTTP Basic authentication in clients: the SRU/W
1336 codec encodes the username/password elements of the PDU structure
1337 appropriately, and these may be set using the "user" and "password"
1338 options in ZOOM-C applications (the same options that are used for
1339 Z39.50 authentication).
1341 --- 3.0.8 2007/06/25
1343 Fixed bug #1208: SSL appears to be broken in ZOOM.
1345 Fixed bug #1206: Libxml2 include path weirdness.
1347 Added oid_name_to_dotstring.
1349 Allow elementSetName to be specified for ZOOM C record update.
1351 Allow waitAction to be specified for ZOOM C based for Extended Services.
1353 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1354 syntax OID. Bug introduced in YAZ 3 series.
1356 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1358 --- 3.0.6 2007/06/06
1360 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1361 directory. yaz-client now reads commands from file given by option -f
1362 if specified; then tries to read .yazclientrc in current directory.
1363 Failing that, it reads .yazclientrc from user's home directory.
1365 Added support for correlationInfo Note and ID for Record Update via
1368 Added yaz-client command querycharset which specifies character set for
1369 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1370 (termListAndStartPoint).
1372 Charset ISO5428:1984 is an alias for ISO5428-1984.
1374 Implemented a way to perform scan in a result set using Z39.50. This
1375 is achieved by attaching the result set name in the characterInfo
1376 (type InternationalString) of OtherInformation in the Scan Request PDU.
1377 The result set is identified in the otherinformation by the new OID:
1378 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1379 This allows for scan in result set and faceted search . Zebra did some
1380 of this in the APT term using attribute type 8 and value being result
1381 set. Using the OtherInformation approach for this is cleaner and easier
1382 to work with in proxies and the like. This facility can be used in
1383 yaz-client using new command setscan which takes a result set as first
1384 argument, start position (APT) as second.
1386 Changed decoding of SRU XML packed records to deal with servers that
1387 have recordData with XML data with multiple root nodes. Also make
1388 comparison for recordPacking case insensitive. Again, one server
1389 returns "XML" where others return "xml".
1391 For SRU responses allow Content-Type application/xml as well as text/xml.
1393 --- 3.0.4 2007/05/21
1395 Fixed bug in character set conversion of BER strings. Bug introduced
1398 --- 3.0.2 2007/05/08
1400 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1402 For OID class, use oid_class consistently.
1404 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1407 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1408 character set for bibliographic information interchange". By Giannis Kosmas.
1410 Added documentation on new OID API.
1412 --- 3.0.0 2007/05/02
1414 Changes to generic frontend server interface: added new member
1415 'query_charset' for bend_initrequest structure. A backend init handler
1416 should set this member to its native character set for query terms.
1417 When defined, the frontend server logic will announce this character set
1418 to a client if the negotiationModel bit is set by the client. All server
1419 implementors are encouraged to specify this. If a backend server does not
1420 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1422 Added CCL utility to remove terms (stop words) from resulting RPN
1423 tree. This is handled by functions with prefix ccl_stop_words_ .
1425 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1426 terms in RPN queries.
1428 Clean-up the CCL API. Moved some internal structures from ccl.h to
1429 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1430 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1431 This is replaced by ccl_parser_find_str which takes a string instead.
1433 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1434 libyaz.la is the core of YAZ except the generic frontend server and
1435 does not depend on POSIX threads anymore. libyaz_server.la is the
1436 generic frontend server facilities and uses POSIX thread functionality
1437 if available. The libyaz.la no longer depends on POSIX threads because
1438 the number of global structures is limited. NMEM no longer re-uses blocks
1439 between threads ; it simply free's memory immediately but allocates in
1440 "large" chunks as usual. We don't expect any performance penalties
1441 because of this. The yaz_log system is still using a global log_level so
1442 caution must be taken when modifying it with yaz_log_init_.. +
1443 yaz_log_mask_str. This, however, should not cause any trouble because
1444 these functions are called during initialization of application code
1445 anyway. `yaz-config --libs server` returns libs for server applications;
1446 `yaz-config --libs` returns libs for non-server applications.
1448 New OID database - with public definitions in oid_db.h. Removed old OID
1449 database including the head oid.h and definitions such as enum oid_value
1450 and struct oident. The new OID database uses the same string names as
1451 before but the 'protocol' is gone. There are now only two representations
1452 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1453 converts from string to OID; functions with prefix yaz_oid_to_string
1454 converts the other way.
1456 Change to emit_term() in CQL-to-PQF query translation: when a term has
1457 the /regexp relation modifier, do not process it for leading and
1458 trailing "^" and "*", which have quite different meanings in regular
1461 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1462 write handlers no longer carries a 'last' parameter. This will make
1463 yaz_iconv flush "less" characters. A flush is performed by call to
1464 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1466 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1467 removed, because function yaz_query_to_wrbuf does the same.
1469 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1470 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1472 Deprecated MARC utility functions removed.
1474 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1477 Branch split: YAZ_2_1_55_branch
1479 --- 2.1.54 2007/03/16
1481 Fix to ZOOM-C so that transparent reconnection is properly handled on
1482 connections that are in asynchronous mode.
1484 Fixed compilation on OpenBSD 4.0.
1486 Large strings in GRS-1 records are now properly displayed in yaz-client.
1488 Added character conversion support for "advancegreek"; based on patch from
1491 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1492 sequence is met. Before the error was not set so it would be unknown.
1494 Adjust yaz-marcdump MARC reader so that it skips until record separator
1497 --- 2.1.52 2007/03/07
1499 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1500 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1501 fd_set structure used as a bitmask for the FDs to be selected on.
1503 Using ACX_PTHREAD macro to check for POSIX threads.
1505 Fixed have-vsnprintf check.
1507 --- 2.1.50 2007/02/23
1509 Fixes for configure on BSD. Bug #900.
1511 Added snprintf/vsnprintf wrappers for systems that don't have
1512 limits (heavens forbid).
1514 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1515 created before all previous tasks were completed and removed from the
1516 task queue, the new task could be removed by a mistake.
1518 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1520 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1522 Fixed bug #832: Problem with MARC/charset in yaz-client.
1524 Fixed bug #668: save command line history for yaz-client.
1526 Fixed bug #830: pkg-config support.
1528 --- 2.1.48 2007/01/23
1530 Extended ZOOM result set options with two options that may be read by
1531 a client: resultSetStatus and presentStatus with values as specified for
1533 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1535 Fixed bug #827: Using SSL fails on Debian etch.
1537 Fixed bug #826: Weird looking chars for set of MARC records.
1539 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1540 that is treated as an ItemOrder with itemRequest being an XML document
1541 external. The value of "doc" is the content.
1543 Extended the GFS search facility. New member of bend_search_rr
1544 'estimated_hit_count' signals that hits is known to be an estmate
1545 (higher or lower than real hit count). New member 'partial_resultset'
1546 signals that the search was partial (hit count is lower or equal than
1547 real hit count). For Z39.50, the information is stored in resultSetStatus
1548 member of SearchResponse APDU. For SRU, the information is signalled
1549 via SRU diagnostic 59: "Result set created with valid partial results
1552 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1554 --- 2.1.46 2007/01/13
1556 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1558 Added ZOOM_connection_peek_event.
1560 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1561 the following new functions:
1562 ZOOM_event_nonblock, ZOOM_connection_process,
1563 ZOOM_connection_get_{socket,mask,timeout},
1564 ZOOM_connection_fire_event_{timeout,socket}.
1565 The existing blocking event handler, ZOOM_event, is a wrapper for the
1566 + blocking ZOOM_event_sys_{poll,select}.
1568 Implemented function ccl_xml_config which parses XML version of CCL
1569 configuration (bug #798).
1571 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1573 Added timings utility (yaz/timing.h)
1575 --- 2.1.44 2007/01/03
1577 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1580 Fixed bug #779: Rotation of apdu.log fails.
1582 Fixed for character set conversions:
1583 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1584 Honor G1 set in MARC-8 decoding.
1586 --- 2.1.42 2006/12/17
1588 Fixed bug #775: char conversion does not handle Alternative UTF-8
1591 Implemented function yaz_marc_read_line which parses MARC line format
1592 records. There is a wealth of formats out there. So far, this function
1593 reads line records produced by yaz_marc_write_line.
1595 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1596 more generic and easier to remember(!) options: -i format and -o format
1597 which specifies input format and output format respectively - where
1598 format is one of "marc", "marcxml", "line", "marcxchange".
1600 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1601 does not print anything except warnings for records.
1603 For yaz-marcdump, added support for MARC split into files (-s) with a given
1606 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1607 spec, at http://www.loc.gov/standards/sru/record-update/
1608 This has changed the binary layout of the following structs:
1609 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1610 bend_update_rr . Patch by Ko van der Sloot.
1612 Added GFS utility function bend_assoc_is_alive which returns 1 if
1613 association is still alive (client is connected); 0 otherwise (client
1614 closed connection). This allows busy servers to stop working for
1617 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1618 been a separate piece of software. This version of ziffy has been modified
1619 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1621 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1623 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1624 Client code may now interrogate options such as "init_opt_sort" to
1625 find out whether the server claims to support various options.
1627 --- 2.1.40 2006/11/27
1629 Added utilities yaz_{set,get}_esn to set/get element set name from
1632 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1633 of YAZ and has been so since YAZ 2.1.10.
1635 Implemented ZOOM_record_error which returns error information for
1636 record (surrogate diagnostic).
1638 --- 2.1.38 2006/10/31
1640 Updates for SRU Update by Ko van der Sloot:
1641 1. Changed name from "operation" to "action"
1642 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1643 versions in the code, marked as 'backward compatible'.
1644 3. Added diagnostics for SRU Update.
1646 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1648 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1650 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1652 For GFS, fixed problem with SRU diagnostic 'First record position out of
1653 range' being issued for 0 hits.
1655 zoomtst10 part of Windows Build.
1657 --- 2.1.36 2006/10/13
1659 Implemented yaz_filepath_comp which splits a path into file path
1660 components (required by Zebra 2.0.3+).
1662 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1663 BSD inspired license until now so this should not have any real impact on
1664 anybody. See http://www.opensource.org/licenses/bsd-license.php
1666 Fixed bug #687: Missing log lines.
1668 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1671 Fixed bug #689: SRU diagnostics to be added.
1673 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1674 whether a connection is idle (no more work do do).
1676 --- 2.1.34 2006/10/04
1678 Change type of optval from long to int for invocation of setsockopt with
1679 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1681 Added support for specifying the max log file size for the Generic
1682 Frontend Server. The size is given with option -r.
1684 --- 2.1.32 2006/09/21
1686 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1688 --- 2.1.30 2006/09/17
1690 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1693 Fixed bug in Generic Frontend Server that could cause a server to stop
1694 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1696 For the generic frontend server, the maximum record size is used as maximum
1697 size of incoming packages (SRU + Z39.50). The value until was previously
1698 only used in Z39.50 Init negotiation and, later, in a session controlled
1699 sizes of records returned. This is controlled using -k option. It can be
1700 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1702 --- 2.1.28 2006/09/04
1704 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1707 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1709 New option for yaz-marcdump -lpos=value which allows setting a portion
1710 of MARC header to a certain value.
1712 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1714 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1715 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1717 --- 2.1.26 2006/08/15
1719 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1722 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1724 --- 2.1.24 2006/08/08
1726 Fixed MARC ISO2709 encoding routines to deal with character set
1729 Minor changes to GFS logging. Database included in search request log
1732 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1733 cached/multiple records.
1735 Shared libraries are built by default on Unix+configure.
1737 Changed cql2pqf transformation to use a different evaluation order. The
1738 new order is: always, relation, structure, position, truncation, index
1739 and relationModifier. Old order was: always, relation, relationModifier,
1740 structure, index, position, truncation. Note that the the latter ones
1741 override former ones for identical attributes.. The new scheme means that
1742 it is possible to override any existing attribute with a relationModifier.
1743 And also that it is possible to override everything for the index rule
1744 (except the ones listed in relationModifier). No order is perfect but this
1745 one, we believe, covers more real cases.. The "always" should have been
1746 called "default", since the attributes there can be overridden with all
1749 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1750 compilation phase, but also for yaz-config --cflags output. This allows
1751 us to have public headers with Libxml2 stuff in them . It should also,
1752 eventually, make Libxml2 checks redundant in packages using YAZ, such
1755 --- 2.1.22 2006/06/15
1757 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1758 stored in uri, message and details.. Previously diagnostics were stored
1759 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1760 compatibility.. but he's probably the only one affected, so.
1762 Added support for CCL, compiled on the client side, in ZOOM-C. This
1763 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1764 input; the resulting query objects can be used for for searching with
1765 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1767 YAZ' configure searches for OpenSSL by default.
1769 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1770 SL_CTX_use_certificate_file. See
1771 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1772 for more info. Thanks to Ko van der Sloot.
1774 --- 2.1.20 2006/06/02
1776 Bug #600: SRU GET, POST support for yaz-client. Introduced
1777 command 'sru' which selects method SOAP/GET/POST.
1779 Allow missingValueAction to be specified for the sortspec string -
1780 function yaz_sort_spec. By default, the missing value action is null.
1781 Use ! to specify "abort". Use = followed by stringvalue to specify default
1784 Ensured that Present-handler (if defined) is called in GFS before any call to
1785 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1786 searchRetrieve requests.
1788 Documentation for YAZ is now based on the Docbook XML/XSLT using
1789 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1790 is no longer depending on jade/openjade or docbook-to-man scripts.
1791 PDF is no longer part of the distribution - but can optionally be
1792 made using DSSSL/jadetex or FOP.
1794 Added retrieval handling support in Generic Frontend Server to support
1795 conversion between MARC/XML as well as XSLTtransforms. See
1796 etc/yazgfs.xml for an example.
1798 Added Authentication support to Generic Frontend Server in SRU
1799 mode. Authentication using HTTP Basic is supported, as is the use
1800 of 'x-username' and 'x-password' parameters in the request itself.
1802 Added support for a new character set MARC8s identical to MARC8 except
1803 that it converts combined characters to single Unicode characters in the
1804 Latin-1 range (when possible).
1806 --- 2.1.18 2006/04/24
1808 ASN.1 compiler 0.4: generates brief Doxygen file header for
1809 generated .h/.c files.
1811 Utility yaz_iconv now supports conversion to MARC-8.
1813 New facilities for the MARC module. The reading - and writing of
1814 content are separate methods for the yaz_marc_t handle. The following
1815 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1816 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1817 format). Write functions have prefix yaz_marc_write_.. The existing
1818 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1819 available. Removed support for OAI-MARC and simplexml (not the
1820 simplexml from PHP5).
1822 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1823 to be returned for this connection.
1825 --- 2.1.16 2006/03/31
1827 Allow multiple languages and charsets to be specified with
1828 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1829 negcharset iso-8859-1,utf-8
1831 Translation of proximity nodes from CQL into PQF now works.
1833 Moved to automake 1.8, 1.9.
1835 Added function yaz_log_set_handler which allows a log handler to be
1836 installed. This handler will be called for all log messages. Output
1837 to file is also produced; but that can be disabled by passing NULL
1838 fname to yaz_log_init_file.
1840 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1842 For SRW (including GFS), accept application/soap+xml as content-type
1845 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1846 produces NO stylesheet reference even if a default stylesheet is specified
1849 --- 2.1.14 2006/03/14
1851 Updated Windows package to include yazd.dll + yazd.lib for the
1852 Development component.
1854 If the environment variable YAZ_LOG is set, then it is used as a
1855 string indicating the default level of logging to use if not
1856 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1857 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1858 used as before. So, for example, to omit warnings from YAZ logging,
1859 export YAZ_LOG=-warn
1861 cql_transform() now map structure and other attributes before indexes,
1862 so that index-specific structures and other attributes can override
1863 defaults. So now a combination of mapping specifications such as:
1865 index.dc.date = 1=date-modified 4=5
1866 does the right thing.
1868 cql_transform() now also respects the "always" mapping specification,
1869 which establishes an initial set of attributes to be used for all
1870 terms except where overridden by more specific attributes associated
1871 with the index, relation or modifier.
1873 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1874 which mode to use; one of "post", "get" or "soap" (SRW, default).
1876 Fixes for yaz_iconv routines: changed trie-based character set conversions
1877 to use only non-negative values for bit fields due to Sun's C compiler not
1878 supporting negative values.
1880 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1881 sequences where not read correctly. Fix by Rustam Usmanov.
1883 Updated win/makefile to use options, settings which makes things
1884 compile with VS C 2005.
1886 --- 2.1.12 2006/02/01
1888 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1890 In ZOOM socket code, use select instead of poll on MacOSX.
1892 ZOOM-C now support client-side compilation of CQL into RPN that is
1893 sent to the server, enabling CQL to be used against all Z39.50
1894 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1895 ZOOM_query object, and submit it using ZOOM_connection_search().
1896 The CQL-to-RPN translation uses a configuration file, the name of
1897 which must be specified in the Connection's "cqlfile" option.
1899 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1900 function, which takes as its start-term parameter a ZOOM_query object
1901 (which may have had either CQL or RPN set into it).
1904 --- 2.1.10 2005/11/29
1906 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1907 GFS to support this as well. Backend handler, bend_srw_update, does the
1908 update work. Code contributed by Ko van der Sloot.
1910 Allow retrieval of Search Result-1 information in ZOOM by the use of
1911 options that are attached to a result set. ZOOM documentation updated
1914 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1915 UTF-8 conversion. Patch by Raj Patel.
1917 Added option -m to GFS to control formatting of timestamps in log file.
1919 Added 'exit' as synonym for 'quit' in yaz-client
1921 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1922 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1923 for the new members. Patch by Ko van der Sloot.
1925 Added support for SRU POST. It is supported for content-type
1926 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1928 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1929 Instead make the library libyaz.la multi-threaded. Threading as a whole
1930 can still be disabled by configure option --disable-threads. Previosly,
1931 with older GLIBCs there were problems with MT libs under Apache. This
1932 has now been fixed a long time ago.
1934 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1937 CQL module modified to be case insensitive for relations/indexes/operations.
1939 Fixed bug in CQL transform code: incorrect value relationModifieder
1942 Added 'show all' command for yaz-client which retrieves all results
1945 Added new yaz-client, xmles, which takes a (private) OID and
1946 a document to be sent as an extended service request.
1948 Describe new yaz-client commands wait_response and set_auto_wait.
1950 Increase TCP/IP listener backlog from 3 (which I am guessing was
1951 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1952 that the socket will queue as many incoming connections as it's able
1953 to handle ongoing connections. In other words, it will never now
1954 refuse a connection that it would be able to handle merely because
1955 it's not got around to accepting() enough of the pending connections
1956 yet. This is the behaviour anyway under Linux, where the listen()
1957 argument is ignored; but not under BSD and on systems such as
1958 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1959 YAZ-based servers should now be uniform across operating systems in
1962 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1963 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1964 This allows yaz-marcdump to read large MARC batches (>2 GB).
1966 Modified all YAZ source files - except the source which is auto-generated
1967 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1970 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1971 corresponding to the existing *_setl() function. These allow option
1972 values containing arbitrary valuues.
1974 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1975 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1976 except that it returns an indicator of whether or not the sort
1977 criterion was accepted (0 for OK, -1 for invalid).
1979 --- 2.1.8 2005/06/07
1981 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1982 MARC output rather than returning "new" buffer.
1984 yaz-client warns about unknown init options.
1986 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1988 --- 2.1.6 2005/05/24
1990 Added support for SRW sort in Generic Frontend Server. Patch
1991 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1992 sortKeys - or NULL if none is provided.
1994 Fixed bug #307: It was impossible to specify indefinite/no timeout
1995 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1998 Added support for multiple languages and charsets to be specified in
1999 ZOOM. Each charset/language is separated by a blank. If negotiation is
2000 in effect in init-response, Option
2001 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2002 Code based on patch by Vasiliy Osadchuk.
2004 Fixed bug #306: infinite recursion that occurred when calling
2005 yaz_log_level_init as the first call (before other log level or
2008 Fixed bug in scan handling in front end server: if preferred-Position-In-
2009 Response was non-present, a NULL pointer referece was performed.
2011 --- 2.1.4 2005/04/26
2013 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2014 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2015 now defined for all those error codes. So instead of putting 109 in
2016 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2017 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2019 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2022 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2024 Program yaz-client now exits and produces an error message if multiple
2025 Z39.50 servers are specified on the command line (none or one allowed
2028 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2031 --- 2.1.2 2005/03/16
2033 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2035 Fixed bug #272: Preserve spacing for CCL terms.
2037 --- 2.1.0 2005/03/14
2039 Added support for virtual hosts and multiple backend servers for
2040 the YAZ frontend server. The configution is XML based and
2041 support specificition of CQL to RPN mappings and explain information.
2042 See section "Virtual Hosts" in the YAZ manual.
2044 Extended OPAC display utility. OPAC display utility renders
2045 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2046 to supplement yaz_marc_decode_wrbuf.
2048 Fixed a bug in MARC decoder that could caused it to crash for some
2049 invalid MARC records. More diagnostics and warnings where added in
2050 XML output (warnings, etc are stored in comments).
2052 --- 2.0.34 2005/02/08
2054 Fixes for UNIX domain sockets. Bug #261.
2056 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2058 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2059 Added yaz_marc_subfield_str which defines subfield lead string which is
2060 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2061 yaz_marc_endline_str which defines end of fields string used in
2062 YAZ_MARC_LINE format. Default string is newline.
2064 Experimental support for MarcXChange. This format can be produced
2065 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2066 http://www.bs.dk/standards/MarcXchange.xsd
2068 Added yaz-client commands scansize that sets maximum number of
2069 entries to be returned by scan.
2071 --- 2.0.32 2005/01/11
2073 Added support for SRW scan in yaz-client and Generic Frontend Server.
2075 * Added whereInList member to SRW Scan Term.
2077 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2079 Fixed NMEM system to return aligned blocks on the smallest boundaries
2080 that are suitably aligned for all possible types on the particular
2081 architecture YAZ is being built for.
2083 --- 2.0.30 2005/01/04
2085 Fixed numerious warnings that was issued with newer versions of GCC.
2087 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2088 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2091 Make YAZ Generic Frontend Server slightly faster.
2093 Enhance (and reduce) logging for Generic Frontend Server.
2095 Revert YAZ log system so that it flushes every write operation
2096 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2098 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2099 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2100 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2101 will effectively disable old definitions.
2103 --- 2.0.28 2004/11/09
2105 Added yaz_log_time_format which specifies log format using
2108 Added yaz_log_module_level which returns mask for a module. Value
2109 is non-zero mask a if module is enabled; zero if disabled.
2111 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2112 in include/yaz/cql.h.
2114 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2116 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2118 Fixed bug #172: RPM builds does not enable SSL.
2120 Doxyfile.in part of dist. Doxyfile generated by configure.
2122 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2123 are given and the corresponding component does not exist.
2125 Extend CCL documentation in YAZ reference. Describe r=r.
2127 --- 2.0.26 2004/10/01
2129 Fixed MARC->MARCXML conversion to properly deal with
2130 fields, subfields, indicators having non-ASCII characters.
2132 Fixed MARC->MARCXML conversion so that ASCII control characters
2133 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2136 Added YAZ GFS support for conversion from Z39.50 surrogate
2137 diagnostics to SRW surrogate diagnostics.
2139 Bug fix: YAZ GFS did not return schema in explainResponse.
2141 --- 2.0.25 2004/09/30
2143 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2144 now converts recordSchema to elementSetName as well as schema URI.
2146 Fixed bug in COMSTACK that prevented HTTP request packages from being
2149 --- 2.0.24 2004/09/29
2151 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2152 does not require white-space before and after the dash in a range, e.g.
2153 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2156 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2157 due to new GCC removing "redundant" code.
2159 Added yaz-client commands scanpos and scanstep that sets preferred
2160 position and step-size for scan.
2162 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2164 Added CCL utility ccl_qual_buf which parses one or more CCL
2165 spec lines in a buffer.
2167 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2168 of name and value - ignoring empty lines and comments.
2170 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2172 Added odr_get_element_path which returns current element path for an
2173 ODR handle. This utility is useful in error handling or user-defined
2176 Added ODR_PRINT utility odr_set_stream which is is a more generic
2177 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2178 to a write function and pointer to close function. The close function - if
2179 non-NULL - will be called during odr_destroy.
2181 Fixed bug in CCL parser where truncation char was not removed from
2182 right side when truncation=both was in effect.
2184 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2187 --- 2.0.23 2004/08/11
2189 Fix buffer overrun in CQL parser when dealing with proximity (%).
2191 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2192 to UTF-8/UCS conversion is now only based on codetables.xml.
2194 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2196 --- 2.0.22 2004/08/06
2198 Add support for more "commit changes" in ZOOM (uses Extended Services).
2200 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2203 Yet another small fix for configure of SSL.
2205 --- 2.0.21 2004/05/14
2207 Fix SSL libs for configure when --with-openssl=DIR is given.
2209 --- 2.0.20 2004/05/10
2211 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2213 SSL comstack now uses yaz.pem certificate file on server side
2214 by default. Certificate filename can be configured by calling
2215 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2217 Fix bug regarding multiple calls to ZOOM_connection_connect.
2219 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2221 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2222 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2224 ZOOM now allows inspection of X509 peer certificate for verification.
2225 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2227 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2228 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2229 as "modular" but it simplifies things.
2231 Added cs_get_peer_certificate to that returns peer X509 PEM.
2233 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2234 NULL if SSL is unavailable.
2236 Documentation about MARC decoding tools.
2238 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2240 --- 2.0.19 2004/03/30
2242 Rename CHANGELOG to NEWS to follow GNU style packing.
2244 Fix bug with missing initialization of member in init_diagnostics.
2245 This bug affects threaded version of GFS server.
2247 --- 2.0.18 2004/03/20
2249 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2252 Ensure zlib.dll is packed with Windows install.
2254 --- 2.0.17 2004/03/17
2256 Fix encoding of xsd:string to use text instead of CDATA.
2258 Fix endless loop in CQL parser with unbalanced ".
2260 Use a more compact way to store MARC-8 conversion tables.
2262 --- 2.0.16 2004/03/16 Debian only
2264 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2267 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2272 --- 2.0.15 2004/03/01
2274 Another fix for decoding of XML packed records.
2276 --- 2.0.14 2004/02/25
2278 Fixes for Chunked encoding. White space not ignored after length spec.
2280 Update NS and use default NS for SRW diagnostic elements.
2282 --- 2.0.13 2004/02/23
2284 Implement ZOOM_resultset_cache_reset which resets record cache.
2286 Implement ZOOM_resultset_sort which sorts a result set.
2288 Implement chunked HTTP transfer.
2290 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2292 --- 2.0.12 2004/02/16
2294 Added member 'schema' to bend_explain_rr structure so that backend
2295 can specify explain record identifier. Defaults to Zeerex 2.0.
2297 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2299 --- 2.0.11 2004/02/16
2301 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2304 Added init command for yaz-client which sends "extra" init request.
2306 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2307 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2309 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2311 Make ZOOM error code for "invalid query".
2313 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2315 --- 2.0.10 2004/02/05
2317 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2320 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2322 Added option -p <file> to make Generic Frontend Server to write PID file.
2324 Added option -D to put Generic Frontend Server in background on its own.
2326 Make ZOOM C recognize option "password". If unset, "pass" is used
2327 (for backwards compatibility).
2329 Fixed a bug in Generic Frontend Server that could make it crash if a
2330 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2333 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2334 Must be issued before open, in order to be in effect.
2336 --- 2.0.9-6 2004/01/12 Debian/Windows
2338 Make the SRU server more picky WRT unknown params, etc.
2340 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2342 New YAZ client command, options, that sets Z39.50 options.
2344 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2345 options from a string of tokens (one token for each option bit).
2347 Update SRW diagnostic code messages.
2349 --- 2.0.9-5 2004/01/07 Debian/Windows
2351 Handle user defined stylesheet for SRW/SRU.
2353 --- 2.0.9-4 2004/01/06 Debian/Windows
2355 Fix bug in decoding of Content-Length.
2357 --- 2.0.9-3 2004/01/06 Debian/Windows
2359 Fix a bug with decoding of XML packed records.
2361 --- 2.0.9-2 2004/01/05 Debian only
2363 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2365 Fix bug in SRW/SRU diagnostics decoding.
2367 --- 2.0.9 2004/01/05
2369 Fixed bug in Generic Frontend Server which could drop records exceeding
2370 preferred message size. Reported and fixed by Irina Dijour.
2372 Fixed calculation of package size for structured records in Generic
2373 Frontend Server. Reported and fixed by Irina Dijour.
2375 Fixed namespace for SRW/SRU diagnostics.
2377 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2379 --- 2.0.8 2003/12/22
2381 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2382 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2385 CQL changes to reflect recent changes to the specification:
2386 * Documentation talks about context sets instead of index sets.
2387 * Documentation talks about indexes instead of qualifiers.
2388 * The CQL-to-PQF transformer's configuration file now uses
2389 "index.set.name = <attributes>" instead of the old form
2390 "qualifier.set.name = <attributes>". (Both forms are still
2391 understood but the latter is deprecated.)
2392 * CQL terms with no explicit index specified are now interpreted as
2393 cql.serverChoice instead of srw.serverChoice (which of course
2394 behaves exactly the same.)
2396 --- 2.0.7 2003/12/16
2398 MARC conversion can now generate ISO2709 output in another
2399 character set. yaz-marcdump uses this facility if you invoke it
2402 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2403 functions from there can be used from C++.
2405 --- 2.0.6 2003/12/04
2407 Frontend server now transfers memory from decoded packages to stream
2410 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2411 references to show up.
2413 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2414 the ZOOM Abstract API. The older names for the same options are still
2415 also supported for the benefit of old applications.
2417 ZOOM-C supports "implementationId" and "implementationVersion" options
2418 to go along with "implementationName". These allow the user code to
2419 specify identification strings to be sent to servers.
2420 Add OID for the new ExtLite attribute set.
2422 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2423 as requested/supplid by Ere Maijala <ere@atp.fi>
2425 For generic frontend server, reverse the order of
2426 "toolkit-supplied / application-supplied" strings sent as implementationId,
2427 Name and Version. Also, remove the spaces around the slash. This brings
2428 the GFS in line with the behaviour of ZOOM-C on the client side.
2430 Add function ZOOM_scanset_display_term.
2432 yaz-client shows scan displayTerm if present.
2434 Utility yaz-iconv is now installed by default along with the man page
2437 Extend configure check for OpenSSL to use pkg-config where available (such
2440 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2441 server to specify uid/gid/mask for socket using the format
2442 unix:[user=uid,][group=gid,][umask=mask,]file=path
2443 If file= is omitted the existing format is assumed, e.g.
2445 in which case the mask is 0666 (rw for everybody).
2447 Major restructure of YAZ source. All source in libyaz is in src directory.
2448 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2449 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2451 Added man page for utility yaz-marcdump (used to be called marcdump).
2452 yaz-marcdump is installed by 'make install'.
2454 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2455 of incoming package failed.
2457 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2459 Change prototype of odr_perror: add const to message string.
2461 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2463 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2464 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2465 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2466 DNS lookup. There should not be any compatibility problems with this
2467 assuming that blocking=1 or 0 is used.
2469 Fix bad reference in UNIX comstack in function cs_addrstr.
2471 Fix for compilation on AIX.
2473 The generic front-end server (server/seshigh.c) now supports returning
2474 Init diagnostics to the client in User-information-field, in
2475 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2478 --- 2.0.4 2003/09/04
2480 Allow any CQL relation (not just all,any,exact,scr).
2482 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2483 that features the same UI.
2485 Implemented command update0 in YAZ client which is equivalent to
2486 update but uses old of Ext Update ASN.1.
2488 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2489 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2490 Previously no OID was used for this info.
2492 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2493 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2494 returns 'malformed search term' otherwise.
2496 SortResponse member resultCount now set to NULL in sort handler of
2499 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2502 Add three new utility functions for translating OIDs between various
2503 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2504 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2505 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2506 char *oid_to_dotstring(const int *oid, char *oidbuf);
2507 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2509 Reverted modifications for ES Update definition for z_IU0Update
2510 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2511 is back to YAZ 2.0.2.
2513 String value attributes for CCL parser.
2515 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2516 which their FirstSearch server returns in Init responses, sometimes
2517 carrying useful diagnostic information when Init fails. This has the
2518 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2519 "z39.50/oclcui.asn", where its definition is somewhat different from
2520 what OCLC document on their web-site, as required to interoperate with
2523 Support for anonymous authentication in yaz-client. Use the command
2526 * Fix the OID of the Index Data-local "admin" Extended Service from
2527 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2528 the 1000, which indicates a locally-defined OID, was a mistake.
2530 --- 2.0.3 2003/06/20
2532 Fix CCL directive @case handling so that it affects string match for
2533 both CCL keywords and qualifiers.
2535 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2536 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2537 Decoder has been updated with ASN.1 changes as listed in
2538 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2539 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2540 z_IUUpdate, remains unchanged.
2542 ZOOM_record_get may now return a record in a specific character set.
2543 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2544 "from" is the character set of record as returned by target. "to" is
2545 the character set to be returned. If omitted, "to" is UTF-8.
2547 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2549 New ODR utility, odr_getelement, which returns name of element for
2550 which encoding/decoding failed.
2552 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2553 in cases where a required element was omitted.
2555 Bug fix: some MARC8 sequences were not converted.
2557 New ZOOM option "step" which specifies number of records to be
2558 retrieved in one chunk. Used in conjunction with "start" and "count".
2560 SRW support for yaz-client. Use scheme http: to use it, e.g.
2563 yaz-client no longer does (un)intelligent character set conversions
2564 by default. Can be enabled with charset and marc_charset commands.
2566 xmalloc trace fix for 64-bit systems such as DEC alpha.
2568 Solaris 2.6 compile fix.
2570 New function, cql_strerror() translates SRW error codes, as returned
2571 by cql_transform_error(), into human-readable English strings. Used
2572 in yaz-client diagnostics when appropriate.
2574 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2575 converts it into a type-1 query which is sent to the server. This
2576 makes CQL available for use with all Z-servers, as opposed to the tiny
2577 minority that can handle CQL queries themselves.
2579 --- 2.0.2 2003/04/28
2581 New Debian package layout similar to the Redhat Package layout.
2583 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2584 and search result respectively.
2586 --- 2.0.1 2003/04/25
2588 Redhat package is now several packages: libyaz (runtime libraries),
2589 libyaz-devel (development and documentation, and yaz (utility programs).
2590 Package spec file by Morten Bogeskov.
2592 New member 'schema' in struct bend_fetch_rr which the name of requested
2593 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2594 handler MAY set this to reflect the schema of the returned record.
2596 New member 'display_term' in struct scan_entry. GFS now sets member entries
2597 and allocates scan entries to be filled by user scan handler. In previous
2598 version, entries member was allocated by the scan handler. That still works,
2599 but the GFS will ignore member display_term - assuming it was NOT set by
2600 the handler. The fact that the GFS now allocates the entries both allows
2601 for new members and makes a scan handler easier to write.
2603 Fix CQL lex buffer overflow.
2605 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2606 SRU default recordPacking is string.
2608 SRU protocol support for frontend server.
2610 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2612 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2614 Added scan for the ZOOM shell (zoomsh).
2618 * String Identifers for Schemas (Amendment 5).
2619 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2620 Old definition for schema
2621 Odr_oid *schema; /* OPT */
2626 Z_InternationalString *uri;
2627 #define Z_Schema_oid 1
2628 #define Z_Schema_uri 2
2631 * resultCount parameter to Sort Response (Amendment 1).
2632 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2634 Support for SRW 1.0 over HTTP. This is an optional feature and
2635 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2638 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2639 on the same port. SRW SearchRetrieveRequests are mapped
2640 to bend_init,bend_search,bend_fetch,bend_close.
2642 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2644 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2645 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2647 ZOOM connections are SRW based if schem http is used for hostname
2648 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2649 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2651 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2652 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2653 distance=n, order=true/false, relation=le, prox unit=word. If
2654 n is omitted, distance 1 is used.
2656 Fixed problem with C compiler include path in wrong order.
2658 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2659 on Solaris. Patch from Ko van der Sloot.
2661 New MARC decode API. All new functions operate on a yaz_marc_t
2662 handle. The most important new functions are: yaz_marc_create,
2663 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2664 decode and destroy respectively. Decoder can produce formats
2665 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2666 include/yaz/marcdisp.h.
2668 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2669 to UTF-8, UCS-32, wchar_t or Latin-1.
2671 * Prototypes for yaz_iconv_-functions moved to separate header
2672 include/yaz/yaz-iconv.h.
2674 Make a few private functions 'static' in unix.c. This prevents
2675 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2677 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2678 are set when Init Response is received.
2680 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2681 but returns diagnostic set as well.
2683 New function yaz_strerror which is a portable wrapper for
2684 strerror/strerror_r/GetLastMessage.
2686 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2687 is returned for MARC. If type is "oai", then OAI MARC is returned.
2689 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2692 --- 1.9.2 2002/11/26
2694 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2696 Fix bad race conditions on SIGTERM and terminate gracefully in
2699 Move retrieval (data1) module to Zebra since nobody seems to be
2702 Add GRS-1 render for ZOOM using same format as yaz-client.
2704 --- 1.9.1 2002/10/05
2706 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2708 Fix broken ESpec handling in data1 module.
2710 SGML reader parses comments and makes them part of the data1 tree.
2712 Added several type casts so that YAZ compiles as C++ code.
2714 ZOOM didn't handle PDU encoding failures properly.
2716 Added more Bib-1 diagnostics (approved extensions).
2718 GNU configure: better check for iconv.
2720 More portable use of accept, getpeername. Check for socklen_t. Use
2721 int/size_t if socklen_t is not defined.
2725 PQF parser rejects bad queries - including those with extra
2726 characters in them. PQF parser used to silently ignore that.
2727 Cleaner API for PQF added, which allows you to get detailed
2728 error information for bad queries (see yaz/pquery.h).
2730 Fixed bug in ZOOM_record_get for type "database".
2732 Implemented mini iconv library supporting conversions between
2733 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2735 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2737 --- 1.8.9 2002/08/20
2739 Fixed ZOOM C record cache so that preferredRecordSyntax and
2740 elementSetName is used to check for already fetched records.
2742 --- 1.8.8 2002/08/02
2744 Added three members in bend_initrequest structure to facilitate
2745 character set negotiation.
2747 Fixed a bug in frontend server that could cause indefinite
2748 loops under rare conditions.
2750 Revised character set utilities (charneg.h) so that encoding
2751 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2753 For PQF, directive @term <type> sets term type for Scan/Search.
2754 Here <type> is general, string, numeric, null. The term type
2755 is inherited - just like @attr.
2757 New call odr_set_charset that sets character set conversion for
2758 international-strings on a ODR stream. Prototype is:
2759 int odr_set_charset(ODR o, const char *to, const char *from);
2760 The InternationalString is still represented as C string in YAZ
2761 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2762 won't). On the protocol level, you can use any encoding.
2764 Support for UNIX sockets in ZOOM.
2766 Solaris recv sometimes returns errno == ENOENT. It is treated as
2767 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2769 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2770 both client and server. Code by Morten Bogeskov.
2772 --- 1.8.7 2002/05/22
2774 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2775 that they can be used directly from Visual Basic. You must recompile
2776 your windows APP if you're using ZOOM.
2778 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2779 Commands "lang" and "charset" sets language and character set respectively.
2780 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2781 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2783 Attributes from multiple CCL fields may be OR'ed rather than merged
2784 using directive "@field or". Fields are still merged by default -
2785 equivalent to "@field merge".
2787 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2790 Fixed bug in zget for parameter ExtendedServicesResponse.
2794 --- 1.8.6 2002/03/25
2796 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2798 Client displays USR.1:SearchResult-1 (hits per term).
2800 Additional Search Info for search in Generic Frontend Server.
2802 Fixed CCL parsing of "field=s".
2804 WIN32 installer - using the excellent NSIS software from nullsoft.
2806 Fixed CCL parsing of "field = - <number>".
2808 Added function yaz_marc_decode that decodes MARC for line mode
2809 display or XML (similar to that used by JZKit).
2811 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2812 Z39.50. But ISO/ILL was, however.
2814 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2815 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2817 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2818 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2820 --- 1.8.5 2002/02/03
2822 New YAZ client features: Command completion and new commands:
2823 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2824 Code provided by Jacob Poulsen.
2826 New call oid_trav, that visits all registered OIDs via callback.
2828 Function ZOOM_record_get now returns const char pointer rather than
2829 void pointer. It saves a lot of type casts.
2831 For YAZ client, command "auth" now allows you to set authentication
2832 in IdPass style. It is enabled when three tokens are given - order
2833 is user, group and password.
2835 Fix memory leaks in MARC record handling for ZOOM.
2837 New option for YAZ client, -k <kilobytes> that sets
2838 maximum record size. Similar to -k option for generic frontend
2839 server and yaz-ztest.
2841 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2843 Prefix query parser reports "fail" when bad attribute set is given.
2845 Fix in MARC decoder. Proximity logging. Fix for attribute set
2846 in scan handler for server. Patches by Shigeru Ishida.
2848 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2851 Configure option --with-openssl=<dir> now works when a directory is
2852 specified. Patch provided by Morten Bogeskov.
2854 New option for YAZ client, -u <auth>, that sets authentication.
2856 ZOOM fix: error information was sometimes "missing", since error
2857 was cleared/reset too when it shouldn't.
2859 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2861 --- 1.8.4 2002/01/04
2863 Scan for ZOOM API. New object ZOOM_scanset. New functions
2864 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2865 ZOOM_scanset_destroy.
2867 New ZOOM function, ZOOM_connection_last_event, that returns type
2868 of last event (such as "receive data", "send data", "apdu received",
2871 New ZOOM option, schema, that specifies schema for retrieval.
2873 New CCL feature. Qualifiers can be aliases for one or more
2874 other qualifiers (if more than one is given, OR is used).
2876 ZOOM uses named result sets if target supports it.
2878 Two new YAZ client commands: . (dot, which sources a script of YAZ
2879 client commands), and ! (to execute shell command.). Implemented
2882 Working on Debian packages.
2884 --- 1.8.3 2001/11/19
2886 YAZ client enables named result sets only if target supports it.
2888 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2890 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2891 with key="host" to get same result.
2893 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2894 Function Z3950_resultset_record(s) returns references to records
2895 "owned" by resultset. To become owner use Z3950_record_clone.
2897 Function z_ext_record handles Extended Services. Thanks to
2900 --- 1.8.2 2001/11/12
2902 CCL Parser fix: ignore token comma when dealing with and-lists.
2904 Documentation updates for COMSTACK.
2906 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2907 Changed prototype Z3950_records. For some functions, int parameters
2908 were changed to size_t.
2910 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2913 New MARC decode/display function, marc_display_exl, which properly rejects
2914 non-ISO2709 records. YAZ client uses it.
2916 --- 1.8.1 2001/10/29
2918 Fix bug: local attribute set wasn't set correctly in PQF strings.
2922 * Old Z39.50 codecs no longer supported.
2924 Added ZOOM C binding. See http://zoom.z3950.org/
2926 Renamed states for COMSTACKs to avoid confusion with events.
2928 Implemented cs_look and proper cs_rcvconnect.
2930 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2932 Configure detects POSIX threads on OpenBSD.
2934 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2935 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2937 When error is returned from present handler, non-surrogate diagnostic
2938 is returned in present response (and fetch handler is no longer called).
2940 * Minor adjustments to pquery parser (PQF). Token characters may be
2941 escaped by using backslash (C-style).
2943 PQF parser allows string attribute values to be specified. For @attr,
2944 non-numeric characters after the equal-sign are treated as strings
2945 (e.g. @attr 9=title).
2947 CCL trunction character may be defined (@truncation in file)
2949 * function zget_ExtendedServicesRequest sets waitAction to
2950 waitIfPossible (was wait).
2952 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2955 CCL operator names may be set in field definition files (CCL_bibset).
2956 See ccl/bib1 for an example.
2958 Fixes in ASN.1 compiler for C++ compatibility.
2960 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2961 and "op_or" to avoid conflict with C++.
2963 Fixed problem with GNU readline detection on Redhat 7.0.
2965 Added step-size for Scan backend handler.
2967 Fixed bug that made the frontend server crash when no attribute
2968 set was specified for scan.
2970 Front-end server automatically switches to original working directory
2971 when installed as an NT service. Previously -w had to be specified to
2974 Added extended attributes for retrieval module (data1), so that data1
2975 records carry d1_readXML/SGML attributes. d1_read also supports
2976 null-data rules ( <tag/>)
2978 On UNIX when POSIX threads are available, a separate library libyazthread
2979 is created. Programmers should link with that library and the yaz library
2980 when using threads. The reason for the split was that some applications
2981 on Linux, such as Apache, doesn't work well when using shared objects that
2984 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2985 (or any frontend server) in SSL mode by specifying ssl: followed by
2986 address. Only tested on UNIX.
2988 Added feature for CCL module. Virtual structure s=al or s=ol generates
2989 and-list and or-list respectively instead of phrase search.
2993 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2994 log_mask_str. This was done to avoid name conflicts with other libraries
2995 (such as other PHP extensions).
2997 Added raw OID member for preferred record syntax (request_format_raw)
2998 and returned record syntax (output_format_raw) for backend fetch method.
3000 Config file yaz-config now accepts options so that it returns specific
3001 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3003 Shared library support for UNIX using GNU libtool.
3005 * Modified backend interface. Request/Response struct's replaced by
3006 one read/write C struct. For example bend_fetchrequest and
3007 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3008 Every handler - even search has to be registered in bend_init
3009 handler. This means that the YAZ library no longer refers to
3010 external functions and it makes it possible to make the whole
3011 thing a single DLL/SO.
3013 Added Segment handler for backend server.
3015 Added Zmbol/Zebra administrative functions to YAZ client.
3017 Threaded frontend server on UNIX (when POSIX Threads are available).
3018 Starting the server with option -T enables multi-threading.
3022 Added configure option --enable-comp/disable-comp to control use
3023 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3024 located in sub directory asn.
3026 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3027 in ${exec_prefix}/bin along with the other programs yaz-client and
3030 GNU automake used to maintain makefiles.
3032 Added several OID's.
3034 Changed retrieval module so that we can load records with no abstract
3035 syntax defined. Tagpaths in these records are fully composed of string
3038 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3042 On UNIX, the generated makefile now supports a proper 'make install'.
3043 The prefix can be set via GNU configure to set the install location
3044 (default is /usr/local).
3046 * YAZ programs client and ztest were renamed to yaz-client and
3047 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3048 locations, such as /usr/bin,/usr/local/bin,etc.
3050 * YAZ Header files were moved from include to include/yaz. YAZ Header
3051 files are referred to as include <yaz/log.h> rather than <log.h>.
3052 The YAZ include path (-I ..) is therefore the same as before. Programmers
3053 should update their #include statements or use -Ipath/include/yaz
3054 instead. The main motivation for doing this change is that YAZ header files
3055 can be installed in "standard" locations /usr/include,/usr/local/include
3056 without introducing conflicts, since ALL YAZ header files are stored
3057 in subdirectory yaz (under /usr/include for example).
3059 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3060 rather than project/workspace files. We switched because project files
3061 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3064 Changed name of logging function, logf, to yaz_log, to prevent name
3065 clash with some math-log functions. The YAZ header log.h defines logf
3066 to yaz_log (#define) so there should be no incompatibilities by this
3069 Added bend_start/bend_stop handlers for server. These handler are
3070 called on start/stop of server. For windows they are called whenever
3071 a service is started/stopped.
3073 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3074 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3075 in util/yc.tcl. The auto-generated C code structures are, in a few
3076 cases, incompatible with the old decoders. There are differences in the
3077 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3078 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3079 The preprocessor variable ASN_COMPILED is defined when the compiled
3080 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3081 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3082 wish to use the old encoders/decoders you can specify --disable-yc
3085 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3086 version so that it supports both new - and old version of DB Update
3088 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3089 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3090 change. The name parameter can be set to 0 in which no name is specified
3091 for the construction. The macros odr_implicit and odr_explicit sets name
3092 parameter to zero for the construction involved. New macros
3093 odr_implicit_tag and odr_explicit_tag are similar to the others,
3094 except that a name parameter is added. For programmers' that don't use
3095 ODR they probably only need to change the call to z_APDU and z_External.
3097 Added access control facility by interfacing the TCP wrapper library.
3098 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3099 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3100 name of the daemon and enables the access control as specified in
3101 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3103 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3104 den Dool <H.M.vdnDool@kub.nl>.
3106 Added reference ID parameter to most functions in server API - refer
3107 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3109 Changed name of ccl library to libccl.a (was ccl.a).
3111 Fixed bug in decoder for Explain (Category TargetInfo).
3113 Added support for GNU readline in client. Thanks to Jacob Poulsen
3114 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3116 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3117 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3118 IMPLEMENTATION! This change was made to the development version before
3119 the ZIG decided to retract the amendment. If any users MUST be
3120 compatible with the original Update definition, PLEASE CONTACT US, and
3121 we will include a separate definition corresponding to the old Update
3122 ES. Note that because of the change to the ASN.1 of the
3123 TaskPackageRecordStructure we cannot define a single structure that
3124 will support both versions.
3126 * Added const modifier to buffer parameter for some ODR/BER encoding
3127 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3128 completeWAIS, odr_dumpBER.
3130 Fixed bug in client.c which caused a crash when a scanResponse didn't
3131 contain positionOfTerm.
3133 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3134 * will cause an error in a client if a non-YAZ target sends both a
3135 * list of Scan entries and non-surrogate diagnostics.
3137 Retrieval module enhancements. Tag sets may be typed in the reference
3138 to it. From the .abs-file the "tagset" directive takes a third optional
3139 integer type for the tag set referenced. From a .tag-file the "include"
3140 directive takes a third optional type as well. The old "type" directive
3141 in the tag set itself is still recognized but acts as the default type
3144 Backend interface change. Individual Scan terms returned from bend_scan
3145 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3146 in include/backend.h.
3148 Retrieval module enhancements. Multiple tag sets and attribute sets may
3149 be specified in abstract syntax specs. Revised the error/warning for
3150 logging messages reported by the retrieval module when reading the
3153 Object Identifier system (oid_..) changed. The API is backwards
3154 compatible but the oid-routines now allocates new OID's when needed.
3155 Raw OID's may be specified in oid_getvalbyname.
3157 YAZ now uses GNU configure to generate Makefile(s).
3159 * Minor changes in some of the member names of DeleteResultSetRequest and
3160 DeleteResultSetResponse. See include/proto.h.
3162 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3163 and added member 'languages' in TargetInfo (which was missing).
3165 Changed the way attribute sets are handled in the retrieval
3166 module. These are now cached, just like the abstract syntaxes
3169 Changed YAZ so that it links with compiled ASN.1.
3171 Added Explain-schema definitions and mapping routines. The following
3172 Explain categories have been implemented: AttributeDetails,
3173 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3175 Fixed minor bug in Windows version of Server Library.
3177 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3179 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3181 Added EXTERNAL: UNIverse Resource Report (non-standard).
3183 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3184 ENUMERATED and SET OF.
3186 * Added 'const' to some of the char pointer arguments for the
3187 functions, data1_read_node, data1_getelementbytagname,
3188 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3191 Fixed bug in data1_insert_taggeddata - the last_child member of
3192 parent wasn't initialised.
3194 * Changed data1_read_record and data1_read_node so that the supplied
3195 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3196 doesn't refer to any parts of the "SGML"-buffer.
3198 Fixed bug in server library (Windows version of statserv_remove).
3200 * Changed code so that it compiles as C++. The type definition
3201 of Odr_fun which is a member of Odr_arm was changed. The result is,
3202 that an explicit typecast is needed for the fun pointer when
3203 using Odr_arm - as in:
3204 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3206 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3208 Implemented the new structured date and time definition as approved
3209 by the ZIG. Added schemaId element to the specificTag in Espec-1
3210 (also approved at the last ZIG). Thanks to RVDM.
3212 Added some Object identifiers (RVDM).
3214 Changed the Update Extended Service (RVDM).
3216 Added command "refid" to client which specifies referenceId for
3217 the following requests.
3219 Implemented extended service handling for server. See ztest.c
3220 for an example as well as backend.h. New handlers are registerd
3221 in the Init handler.
3223 * Changed interface for sort in server.
3225 Added new members to statserv_options_block. It allows a server
3226 to read options from another source than just the command line. Thanks
3227 to Charles Woodfield.
3229 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3230 renamed to zboolean. Some C++ compilers complained about the name.
3232 Minor changes to gils.abs. Added index 's' (sort) on title
3233 and date/time-last-modified.
3235 --- 1.4pl2 1998/1/30
3237 Fixed bug in server library regarding inetd mode (-i). This bug
3238 was introduced by release 1.4.
3240 --- 1.4pl1 1998/1/29
3242 Added sort facility in client and backend server interface.
3244 Fixed problem with dependencies in Makefile(s).
3246 Fixed bugs for encoders/decoders of extended services and
3249 Implemented sub-tree feature for schemas. Sub-trees are
3250 referenced in *.abs-files. See explain.abs for an example
3251 of the use of this feature.
3253 Modified bib1.att; local attributes for ANY didn't include
3254 ANY itself (only affects use of the retrieval module).
3256 Fixed bug in plain SGML reader in function data1_read_node:
3257 tags with prefix "var" was incorrectly interpreted as variants.
3259 Added feature "sub-schemas" to enable references to - and definitions
3260 of - group of elements.
3262 * Removed member parent from type data1_element (in data1.h).
3264 Implemented function odr_nullval() that returns the value of
3267 * Removed member num_children from data1_node (in data1.h).
3269 Made NT service interface part of the server library. The
3270 function statserv_main uses the NT service when required and
3271 calls the statserv_start / statserv_close routines.
3273 Routine zget_SearchRequest and zget_PresentRequest fills
3274 resultSetName/Id member with "default" instead of "Default".
3276 Fixed memory leak in server. Request queue member wasn't freed.
3278 Fixed nmem_exit so that memory is freed.
3282 Revised the CCL parser utility to be thread safe.
3284 Added function, oid_ent_to_oid, to replace the function
3285 oid_getoidbyent, which is not thread safe.
3287 * Added nmem_init and nmem_exit to initialize and release
3288 NMEM resources. Function nmem_init should be called once in the
3289 initial thread before NMEM/ODR is used. statserv.c and client.c
3290 have been changed accordingly. The change was necessary to make
3291 NMEM thread safe. The NMEM memory pool is shared amongst threads
3292 in a process. Unix-based applications will still work fine without
3295 Added NT Services interface for the the Z39.50 (statserv) Server.
3296 Refer to the ztest.c source on the usage.
3298 Windows 95/NT port using MSVC5.0. Project files are included in the
3301 * Defined new 'global' handle for the retrieval (data1) system. The
3302 new handled, data1_handle, describes the state of the data1 system.
3303 This handle is passed as first argument to virtually all
3304 data1 related routines. The functions data1_create and data1_destroy
3305 creates and destroys a data1 handle respectively.
3307 Added ODR encode stream member to all backend request structures
3308 init, search, scan etc. This stream should be used to allocate all
3309 memory used for the response when thread safe operation is needed.
3311 Changed the comstack utility, cs_addstr, to be thread safe. The
3312 returned hostname string returned by the function is now part the
3315 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3316 function. The cs_straddr takes a COMSTACK handle as argument, so this
3317 function must be used after cs_create and before bind/connect.
3318 This function is thread safe.
3320 Moved test server to 'ztest' directory - generic server code still
3321 in 'server' directory.
3323 Made prefix query (pquery.c) utility thread safe.
3325 Added new function modifier YAZ_EXPORT to 'export' public DLL
3326 functions when using windows (see include/yconfig.h).
3328 Added definitions to the OID database (util/oid.c) (RVDM).
3330 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3332 Added call to ccl_rpn_delete in client program.
3334 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3335 release of RPN structure.
3337 Added support for C++, headers uses extern "C" for public definitions.
3338 With input from RVDM.
3340 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3341 Thanks to Ronald van der Meer (RVDM).
3343 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3345 Added support for private extensions to the OID database
3346 (oid_setprivateoids()). Thanks to RVDM.
3348 Added optional, physical ANY (key replication)
3350 Fixed null-reference problem in GRS-1 output filter.
3352 Proximity operator added to Prefix Query Format (PQF).
3354 In test client command "base" accepts multiple databases.
3356 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3360 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3362 Smallish bug-fixes in the new encoders/decoders (explain).
3364 Bug fixed in DeleteRequest.
3366 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3368 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3370 Added SOIF syntax (using private OID for now) to retrieval module and client.
3372 Added Update extended service.
3374 Added SearchResult-1 additional info structure.
3376 Added optional CCL (ISO8777) interpreter as separate module. Available
3379 --- 1.2 1996/6/10 (1st anniversary release)
3381 Added Summary record syntax. Lightly tested.
3383 Added OPAC record syntax. Untested.
3385 Added ResourceReport service encoders/decoders. Untested.
3387 Fixed bug in z_Unit - wrong tagging on unitSystem.
3389 Fixed bug in the DiagRecs decoder.
3391 Added options for max PDU size and session timeout to frontend-server.
3393 Added documentation of query-language parsers and other supporting utilities.
3395 [frontend-server] Added Attribute set to the bend_scanrequest API.
3397 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3398 surrogate diagnostics were generated.
3400 [retrieval] Allow multiple local values for attribute.
3402 [retrieval] Allow multiple attributes per element in .abs files. index type.
3404 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3406 --- 1.1pl2 1996/4/10
3408 Minor changes, mostly specific to Zebra's requirements (retrieval)
3412 Repaired bug in frontend server when running multiple listening
3413 endpoints in dynamic mode.
3415 z_External() now won't break if a known, ASN.1 value comes encapsulated
3416 in an octet-string. The value will pass through unmodified in an Odr_oct.
3418 Added a bit of code to the demo client to decode & display
3419 ASN.1-structured records represented in the octet-aligned branch of
3420 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3422 Added z_ext_getentbyref() to the ASN module. Doc updated.
3424 * Completed the SCAN definition in the ASN module. This may break SCAN
3425 code based on older YAZ-versions at compile-time. The fix is easy -
3428 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3429 under the SCAN definition. Remember to initialize this, server-people.
3431 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3432 that this does not extend to ODR and ASN.
3434 Comstack allows insertion of established socket (primarily for
3435 inetd-operation of servers). Doc updated.
3437 Front-end server can now start from the inetd in TCP mode. Doc
3440 --- 1.0pl4 1996/1/24
3444 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3445 the rank and record number.
3447 Adjustments to the frontend server.
3449 Fixed diagnostic BER dumper. It ignored the file argument.
3453 Various changes to retrieval module.
3455 Changed the union discriminators of the protocol files from enums to
3456 ints paired with #defines.
3458 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3461 *Changed operator in the RPN structure to 'roperator', again to avoid a
3464 Fixed problems in Explain decoders/encoders.
3466 --- 1.0pl2 1995/12/6
3468 Memory bug in log module fixed.
3470 --- 1.0pl1 1995/12/5
3472 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3474 Bug in Explain DatabaseInfo module fixed.
3476 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3480 The shift to v1.0 signals that we now consider the *core* functionality
3481 of YAZ reasonably stable (the core being more or less equivalent to
3482 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3483 tested (Explain not at all - though that will happen soonish).
3485 Minor changes to code to support Windows port.
3487 Various minor changes after we're getting to use GRS-1 & co. more.
3489 Added Espec-1 format.
3491 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3492 of the protocol and it cannot be selected when encoding (maps into 'string'
3493 when decoding). Needed to talk to some servers.
3495 Demo client can request simple element set names.
3497 Added Diagnostic Format encoders/decoders.
3499 Added simple Close handling to frontend server (no hooks for resource
3500 reporting yet), and demonstration client.
3502 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3504 --- 1.0b3 1995/08/24
3506 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3507 handled incorrectly when records were requested in the searchResponse. This
3508 will only affect you if you use the frontend-server.
3510 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3511 Test-client will ask for and print GRS1. Ztest will return dummy records
3514 Added Explain encoders/decoders to the service-level API. Untested.
3516 Added Extended Services: Item Order encoders and decoders to the Service-
3517 level API. Untested. We could use a recent copy of the pertinent bits
3518 of the ILL protocol to add those bits.
3520 Added diagnostic format 1 encoders/decoders to the service-level API.
3523 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3524 odr_cons.c, which causes a more correct output.
3526 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3527 was always set to 0 when no records were requested in the searchRequest.
3529 * Added better external-handling. This shouldn't harm old code that
3530 *encodes* externals. It can break code that looks for a
3531 'single-ASN1-type' representation, since those types that are known
3532 are now decoded immediately. Look at the SUTRS sample code in
3533 seshigh.c and client.c. Documentation updated.
3535 Handling of structured records in bend_fetchresponse. Length -1 marks
3536 structured record, type is deduced from format field.
3538 --- 1.0b2 1995/06/27
3539 Fairly quick maintenance release to add SUTRS support.
3541 Fixed handling of SUTRS records in the demonstration client.
3543 * Added format field to the bend_fetchrequest and bend_fetchresponce
3544 structures of the backend API (frontend server). When the record is
3545 returned, the value of the format field is mapped to an OID. The
3546 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3547 of the record. The special value VAL_NONE in the bend_request means
3548 that no specific format was requested by the client. Documentation
3549 updated accordingly. Test server (ztest) will return a fixed dummy
3550 SUTRS record if your client requests SUTRS.
3552 Documentation updated accordingly.
3554 You can now set external libraries and RANLIB support in the top-level
3558 First public release.
