3 Fix proxy/host problem for ZOOM that could occur if unix sockets
6 New Debian package libyaz4-dbg.
8 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
9 differently in tcpip_close.
13 Windows installer of YAZ includes YAZ4J as a component.
15 CQL: allow "extra terms" again, by default. Thus, the CQL parser
16 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
17 and earlier. CQL parser may operate in strict mode where queries
18 not conforming to the standard BNF are rejected (syntax error).
19 Whether the CQL parser operates in strict mode is controlled with
20 cql_parser_strict . Strict mode enabled with option -S for utilities
21 cql2pqf and cql2xcql .
23 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
27 New charset, MARC-8c, which is like MARC-8 but allows control characters
28 0x01 through 0x1F, except ESC to be passed through verbatim.
30 Fix a problem with duplicate sub field character in MARC output. Problem
31 happened only when output was MARC-8 encoded.
35 yaz-ztest: Use hash for fake hit count. Before, random number was used.
36 This is problematic for unit tests using yaz-ztest. This patch also makes
37 a hash for CQL queries. For RPN, any term with a leading digit will be
38 treated as pseudu hit count (to force any particular hit count by a client).
40 yaz-ztest: return unique MARC dummy records. Beyond record offset
41 24, the author surname is patched with offset to make all records
44 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
45 on system wide default (/proc/sys/net/ipv6/bindv6only).
46 @4 binds to IPV4 only. @6 binds to IPV6 only.
48 Update CQL API documentation a bit
50 CQL: don't accept extra terms for queries. Makes the CQL parser
51 stricly conformant to the standard.
55 GFS: scan handler gets extra_args from request and may return extra
56 response data . That's for SRU only.
58 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
62 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
64 OPACXML: sync spelling of availabilityDate in XML to that of Schema
65 opaxxml.xsd. The schema had the correct spelling of this member always.
66 The ASN.1 was mis-spelled and still is (API change) - we are
67 not changing this. However, the OPAC to XML conversion had yet
70 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
73 New function, z_ext_record_oid_nmem, which is similar to
74 z_ext_record_oid but takes NMEM rather than ODR
78 ICU: New conversion element 'join' which joins tokens into one
79 with a custom character given by rule attribute.
83 New GFS search member: present_number. This is a hint to the
84 search handler how many records are going to be fetched immediately
85 following search. There's no guarantee that it's going to be the case,
86 since it depends on hit count (for Z39.50 piggyback) and whether errors
89 Make a few functions static (private). The functions getbyte_stream,
90 ungetbyte_stream and yaz_gets are now private. They were never declared
93 yaz-marcdump: exit(5) for serious decoding errors
95 ISO2709 decoding: be more picky WRT header
97 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
98 was only used as to indicate that next-result-set-position should be
100 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
101 Based on patch from Ashley Sanders.
103 Make some functions static/private in PQF parsing. Those functions were
104 never declared in a public header and so should not be in use by
105 applications based on YAZ.
107 --- 4.2.47 2012/11/23
109 ZOOM: special options to control APDU logging.
110 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
111 logging of APDUs until "saveAPDU" option is set again. If logging is
112 already enabled the effect is that current APDU buffer is cleared.
113 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
114 logging (default behavior on new connection).
115 The APDUs sent/received can be obtained by using
116 Using ZOOM_connection_option_get(c, "APDU") or
117 ZOOM_connection_option_getl(c, "APDU", &l).
119 GFS: relay implementation_version from backend
120 From 3.0.40 and later, implementation_version from backend was
121 not used in init response at all.
123 --- 4.2.46 2012/11/15
125 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
126 mode at all. Probably never did.
128 Make a new version of ztest.pem that, at least, is not expired.
130 --- 4.2.45 2012/11/13
132 Fix description of CCL directive 'case'.
134 More tight checking of form arguments (yaz_uri_to_array). Makes
135 YAZ better at rejecting big and/or bad POSTs.
137 SRU decoding does not report more than up to 10 invalid arguments.
139 rpn2cql: less quotes in generated terms. Semantics unchanged, but
140 it's prettier this way.
142 --- 4.2.44 2012/10/25
144 New utility yaz_decode_init_diag. Defined in proto.h.
146 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
147 given for unix local socket.
148 The COMSTACK string for doing so is:
151 unix:/myfile:tcp:localhost:9999/mybase
152 unix:/myfile:localhost:9999/mybase
153 unix:/myfile:http://fakehost/mybase
155 debian: Use dpkg-buildflags in build process.
157 --- 4.2.43 2012/10/19
159 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
160 global's SRU service uses a recordPosition scheme starting from zero.
161 First record's position should be one
162 according to the standard.
164 --- 4.2.42 2012/10/18
166 Allow more namespaces for SRU. This is to allow, for example, an
167 incorrect namespace returned from server
168 http://services.igi-global.com/sru .
170 Minor fixes for compilation on Windows.
172 --- 4.2.41 2012/10/11
174 daemon: log total number of bad signals from child on stop so that it
175 is more easy to spot problems with child worker processes.
177 retrieval: empty backend name attribute omits element set
178 from being used in retrieval.
180 --- 4.2.40 2012/10/04
182 Implement Solr sort strategy "solr", similar to sru11 sorting.
183 This will implement the correct parameters on Solr requst to do
186 --- 4.2.39 2012/09/28
188 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
191 MARC: Extra/missing indicator handled for MARCXML.
192 The indicator length is given in header and is the same for the
193 whole record. If attributes ind1, ind2 are missing, then content
194 character defaults to blank. Extra indicator attributes (beyond)
195 indicator length are treated as an error.
197 Reformat: delete trailing whitespace
199 --- 4.2.38 2012/09/17
201 MARC: fix non-ASCII characters for leader. This is to ensure we can
202 generate XML in UTF-8.
204 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
205 in one node with structure word.
207 --- 4.2.37 2012/09/04
209 yaz-json-parse: JSON output may be pretty printed by using option
212 Increase default value of max message for Z39.50 Init for GFS, ZOOM
213 and yaz-client. Old value was 1 MB. New value is 64 MB.
215 --- 4.2.36 2012/08/22
217 yaz-client: don't display bogus records from SRU servers. Some SRU servers
218 return more records than given by *maximumRecords*. Skipping those in
221 record_render: simplify buffer return handling and fix at least one bad
222 memory reference, that broke the test_embed_record sometimes.
224 Allow http://user:pass@host notation for yaz_url_exec.
226 zoomsh: allow shell command to be executed. Via the system(3) call.
228 yaz_poll: Allow num_fds == 0
230 yaz-client: fix bad encoding of "itemorder item". The itemorder
231 item <no> - command forgot to use length of encoded Item Request
232 package. Error present since YAZ 3.
234 yaz-ztest: fix bad usage of session handle. Bug was introduced when
235 result sets were saved (271a9c83).
237 SRU recordPacking: guess record packing in response rather than looking
238 at the recordPacking element which, OF COURSE, changed semantics in SRU
241 Decode SRU 2.0 responses. The official namespace for responses, according
242 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
243 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
244 nature.com's server, however, usee namespace
245 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
246 we are now using a glob-expr to match up the namespace. ZOOM C and
247 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
248 I can not find a single real example showing the "real" namespace in
249 the documentation from OASIS. The namespace for requests is different
250 from responses, but this is not added to YAZ yet, when we don't encode
253 --- 4.2.35 2012/06/26
255 zoom/record_render: add support for Base64 decoding fo MARC records
256 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
257 which will decode base64 + ISO2709 marc-8 encoded material from text node
260 --- 4.2.34 2012/06/07
262 Add missing definitions ZOOM_resultset_get_facet_field_by_index
263 and ZOOM_resultset_facets_names.
265 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
268 Change APDU dump printing to avoid long leading blanks. For levels 16
269 or larger the level is shown and the indentation is truncated but
270 recursed with modula 8. This makes it still reasonable easy to read
271 - even for nested BER dumps.
273 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
274 return 0 (incomplete package) in case where the BER package was
275 considered too nested (return value of -2).
277 dumpber: lines of level 15 are not indented further. Two spaces per
278 indentation; indentation 15 or more is indented to a fixed indentation
279 and augmented with a level=<no> indication.
281 zoomsh: increase max size of command+args
283 GFS: No limit in RPN buf size in CQL to RPN conversion.
285 --- 4.2.33 2012/05/09
287 New function for daemon utility, yaz_daemon_stop .
289 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
291 --- 4.2.32 2012/04/25
293 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
294 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
296 --- 4.2.31 2012/04/23
298 YAZ daemon utility relays SIGUSR1 to child process.
300 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
301 would result in en empty database list - which in turn would result in
302 encoding failure for search.
304 Fix reading beyond string in yaz_sort_spec.
306 --- 4.2.30 2012/04/11
308 Add two new SRU diagnostics:
309 236: Access to specified database denied
310 1015: Init/AC: Maximum number of simultaneous sessions for Userid
312 Document the very useful ZOOM-C option "apdulog".
314 CQL to RPN: term may be passed through verbatim. This is enabled with
315 truncation.cql . The assumption being that the term is already CQL.
317 --- 4.2.29 2012/03/20
319 record_conv: leader spec may be given for marc element.
320 The leader spec is given as attribute leaderspec for element marc.
321 For example to convert a MARC21 record from MARC-8 to UTF-8:
322 <marc inputformat="marc" outputformat="marc"
323 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
325 record_conv: allow user-XSLT params. For example:
326 <xslt stylesheet="MARC21slim2DC.xsl">
327 <param name="myparameter" value="myvalue"/>
328 <param name="otherparameter" value="othervalue"/>
331 record_conv: fix error handling for missing marc charsets.
333 CQL: fix extra terms in wrong order.
335 --- 4.2.28 2012/03/06
337 record_conv: modify new API for conversion types. The conversion types
338 may be passed in new functions yaz_record_conv_configure_t and
339 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
341 Avoid mixed statement/variable declare; fixes compilation with Visual
344 --- 4.2.27 2012/02/28
346 Add non-standard SRU diagnostic: 235: "Database does not exist".
347 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
348 Update SRU to Bib-1 diagnostic maps accordingly.
350 CCL: add two new diagnostics for unsupported masking. The new
351 diagnostics are: "Embedded truncation not supported" and
352 "Single charcacter mask not supported".
354 --- 4.2.26 2012/02/23
356 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
358 --- 4.2.25 2012/01/11
360 Build YAZ for Ubuntu Oneiric.
362 CCL: allow parantheses for proximity operands. For example CCL query
363 (a) % (b) is now allowed.
365 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
366 marked dead, rather then being destroyed. If not, the session memory is
367 being free'd before the search/scan handler is finished. Also destroy
368 'request' memory in request_release rather than in various places,
369 which resulted in leaks from time to time.
371 --- 4.2.24 2011/12/21
373 cql_sortby_to_sortkeys: honor sort prefix.
375 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
376 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
377 The rpn2cql family of functions now always returns quoted CQL terms.
379 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
381 --- 4.2.23 2011/12/15
383 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
384 sequence is treated as one. For example, &&a=b&&&c& is identical to
387 --- 4.2.22 2011/12/05
389 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
390 APDUs for a connection to a WRBUF.
392 --- 4.2.21 2011/11/23
394 Fix cql_sortby_to_sortkeys. Completely broken before.
396 Make CCL's @truncation work again.
398 --- 4.2.20 2011/11/09
400 New ZOOM connection setting: tproxy. It's like proxy, but does not
401 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
402 to set resolved address + port for a connection outside ZOOM itself.
404 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
406 --- 4.2.19 2011/11/07
408 Fix uninitialized variable in Solr spell support (could cause SEGV
409 for SRU response decoding).
411 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
412 back-end's addinfo through into the ZOOM response addinfo.
414 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
415 they are separated by a colon and a space rather than simply
418 --- 4.2.18 2011/10/28
420 Add support for Solr spell-checking/suggestions through ZOOM.
421 If a Solr target has been configured correctly for spelling-checking
422 and suggestions, these will now be returned on the ResultSet option
423 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
425 --- 4.2.17 2011/09/28
427 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
428 with a flag whether to substitute escape sequences or not.
430 --- 4.2.16 2011/09/22
432 Fix nmem_strsplit_escape to substitute escape char properly.
434 New option for zoomsh -e , which makes it abort on first error and
435 return process exit code to indicate success/failure.
437 YAZ options utility supports special option -- which makes all it treat
438 all following arguments as non-options.
440 --- 4.2.15 2011/09/16
442 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
443 searched if absolute filename is given.
445 Fix conv_xslt() error-reporting when stylesheet is not found.
446 (The value of fullpath is meaningless in this situation.)
448 --- 4.2.14 2011/09/07
450 Fix problem in CQL sort node creation: un-initialized memory.
452 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
453 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
454 CQL sortby depending on whether Type-1 or CQL is actually sent to the
457 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
458 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
460 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
461 will make it possible to use both single-character mask (#) and wildcard (?)
462 in CCL . Throw diagnostic for left truncation because that is not supported
465 --- 4.2.13 2011/09/01
467 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
468 cases using escapes (\-sequences) and masking.
470 PQF parse fix: A trailing backslash followed by end-of-string (\0)
471 would result in a read one byte beyond string.
473 rpn2ccl may use Z39.50 masking for terms (t=z).
475 ICU check fix. Don't include library -lCrun on Solaris, unless present.
477 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
478 not --cppflags (which seeems like an error in icu-config).
480 --- 4.2.12 2011/08/27 RPM package only
482 cql2ccl: fix conversion of terms: operator characters were not
485 --- 4.2.11 2011/08/25 RPM package only
487 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
488 CCL parser will map both # and ? to their regular expression
489 quivalents (. and .*).
491 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
492 of reserved CQL characters.
494 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
495 is, so that they are passed through.
497 --- 4.2.10 2011/08/24
499 ZOOM SRU mode: more aggressive re-connect.
501 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
502 made available as a utility function, declared in <yaz/logrpn.h>
504 rpn2cql_structure() supports proximity nodes (except that the Type-1
505 proximity node's "exclusion" binary is ignored, as there is no way to
506 express that in CQL). Fixes bug #4564.
510 Fix SEGV that could occur if set command of zoomsh was given without
511 value (2nd argument).
513 Fix SEGV that could occur if unsupported transport was given for
514 COMSTACK - say https (when SSL was unavailable).
516 Build yaz-url on Windows too.
520 New utility to get web content. Header is url.h. A command line tool
521 yaz-url is part of the distribution and packages.
523 Fixes for SSL COMSTACK (when gnutls is in use).
525 New functions yaz_base64{encode,decode}. Header is base64.h.
529 ZOOM C includes HTTP response buffer as additional info if it fails
530 to decode the SRU response.
532 Make wrbuf_json_puts available.
536 zoom: throw diagnostic for invalid value for option "sru". Before a
537 bad SRU request was sent.
539 Adding new utility wrbuf_vp_puts.
541 Add cclxmlconfig.obj to win/makefile. It was missing completely.
545 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
546 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
547 redirect was used at the same time.
549 MARC line mode decoding: be less picky about length given - first
550 5 digits of header that is.
552 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
554 Changes to decoding of SRU records: a record with recordPacking=xml is
555 modified with a new root element <yaz_record> if the recordData contains
556 multiple children elements. This is to make the record XML parseable
559 RPN to Solr conversion: encode special characters.
561 Generic Frontend Server: fix uinitialized member, stepSize.
565 Fix a bug in SRU decoding of records.. The database records stored
566 had un-initialized memory, but it would only be seen with yaz_record_render
567 and type_spec="ext" .
569 Fix a bug in ccl_qual_dup introduced in 4.2.3.
573 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
577 Add new utilities to convert from CQL to CCL . These utilities have
578 prefix cql_to_ccl defined in cql.h.
580 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
581 lead to memory heap corruptions when ICU utilities were in use.
585 Make compilation work without Libxml2.
587 yaz-client: remove redundant blanks in display of searchResult-1 term
592 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
593 resulting CQL node (tree) in a new node CQL_NODE_SORT.
595 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
596 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
597 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
598 Note that the CQL sortby spec is only converted when the GFS is already
599 converting from CQL to RPN (cql2rpn element).
601 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
602 specify whether to collapse delimitors or not. The existing nmem_strsplit
603 do collapse (collapse parameter = 1).
605 Windows installer: For NSIS, set InstallDir depending on x86/x64.
607 Rename internal func yaz_use_attribute_create. While non-static, this
608 function is not declared in a public header.
612 Add -lCrun when linking with ICU on Solaris.
614 More quicks character set conversions for OPAC records.
618 fix problem with record_render: records were converted (character set
619 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
623 SRU: add methods for handling DADS SRU-proxy facets.
625 Separate OPAC record character set for ZOOM_record. yaz_record_render
626 allows a character set given as charset=from/opacfrom,to where 'from' is
627 the character set of a bibliographic record, 'opacfrom' is character set
628 of OPAC record and 'to' is the target character set.
632 yaz-client: show may XML format records. Command show followed by 'format'
633 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
636 src/stemmer.c: Avoid using unnamed union. It is not supported by some
639 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
642 Update yaz.spec to operate on both SLES11 / Centos 5.5.
644 RPM: Release includes 'indexdata' name. Use indexdata in release name so
645 this package can be distinguished from other vendors.
647 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
648 as determined by configure
650 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
652 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
653 returns no error and no record, the present request is considered
654 partial (only a subset of the records could be returned by backend), and
655 so it is appropriate to set Present Status to partial-4.
659 Move yaz-config man pages to section 1.
661 More documentation about Solr.
663 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
664 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
665 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
666 peers on some Linux systems. However, in general that does not work
667 so YAZ can not rely on that to work. Debian changed behavior in this
668 respect from Debian lenny to Debian squeeze (still testing as of Oct
670 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
672 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
676 Fix yaz-config output: echo_source not set correctly by configure.
680 Solr Web Service support for yaz-client and ZOOM.
682 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
684 --- 4.0.12 2010/08/17
686 Z39.50 facet support. Facet specifications are passed for search in
687 other-information with ASN.1 as defined in facet.asn and OID
688 .10.1000.81.5 . Facets are expressed as an Attribute list as known
689 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
690 3 is limit (number of entries to get in response). yaz-ztest returns
691 dummy facets if a client asks for them.
693 --- 4.0.11 2010/07/09
695 CCL fixes: bug 2895 and bug 3539.
697 GR1-display: add comma in display - was removed by mistake in
700 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
702 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
704 --- 4.0.10 2010/06/18
706 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
707 result set from a connection. The result set will be on its own
708 thereafter; no operations on it will perform retrievals from a target.
709 Only cached copies are returned.
711 ZOOM C:fix case for HTTP servers responding with Connection:close.
712 Ensure that if there is a current task it is resumed (like fetching
713 more records in a result set) . Bug #3484.
715 PQF parser: use odr_atoi for Odr_int (not atoi)
717 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
718 values that contain any non-digits are treated as string attributes
719 (previously decoding only checked for leading character ([0-9]). PQF
720 encoding: attribute string values are not surrounded by double-quotes.
724 New utility for managing threads - thread_create.h.
726 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
727 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
728 but YAZ' implementation do.
730 Fixes for yaz_cond-functions on Windows 7.
732 DLL export more symbols.
734 zoomsh: show record do NOT render opac.
736 Remove *.la files from Debian and RPM packages.
740 Debian package libyaz-dev depends on libgnutls-dev again (was
741 removed in YAZ 4.0.6, but due to Libtool it is still needed
742 even though yaz-config do not list libgnutls libs).
744 ZOOM: Use only one WRBUF for returning string results for
745 ZOOM_resultset. Reduces memory usage for ZOOM in general.
747 ZOOM: ZOOM_connection do not use a shared pointer to
748 ZOOM_resultset after ZOOM_resultset is destructed by
749 user. Reverts to YAZ 4.0.4 behavior.
753 record-conv: fix problem with at least one XSL conversion -
754 due to probably incorrect usage of XML XSL documents.
758 Fix yaz-config for static mode and the use of SSL (gnutls).
762 Forward decl timeval struct in mutex.h and gettimeofday.h.
764 yaz-config: fix 'static' mode linking.
768 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
769 are wrappers for pthreads or Windows. For Windows these are put in
770 a separate DLL: yaz_cond4.
772 libyaz.la (whole source) is compiled with thread. If thread support
773 is enabled enabled, all source of YAZ is compiled with treading support.
774 This allows core utilities such as yaz_log to use thread facilities.
775 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
776 thread utilities. This commit moves mutex utilities (mutex.c) from
777 libyaz_server.la to libyaz.la.
779 yaz-json-parse displays leading text until error.
783 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
784 patch from Giannis Kosmas.
786 SRU: no longer URL encode SRU database. The URL for an SRU server is
787 a URL and such is alreeady encoded - at least when given with leading
788 http:// or https://. This reverts behavior to YAZ 3.0.50.
790 Support for new MARC XML notation TurboMARC which like MARCXML is a
791 complete representation of MARC/ISO2709.. This one, however, is more
792 compact and allows for faster processing with XSLT. TurboMARC can be
793 used in the marcdisp.h API, from the yaz-marcdump utility and from
796 yaz-ztest can be configured - via the database - to perform certain
797 delays when it performs operations search, present and single record
798 fetch. This allows testers to make yaz-ztest act as a real or even slow
799 Z39.50 server. Refer to the yaz-ztest man pages for details.
803 wrbuf_destroy allows NULL WRBUF passed to it.
805 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
807 Add ZOOM_connection_close.
809 No fixed size buffers for ZOOM shell - bug #3257.
811 tstodr: make it work on s390 platform.
813 New icu iterator-functions. The new icu_iter-functions makes it possible
814 to use ICU chains from many threads.
816 yaz-client: better syntax check for show command.
820 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
823 New simple local-file XML include facility which allows file glob-patterns.
824 Refer to yaz/xml_include.h.
826 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
829 ZOOM_record_get supports new parameter "format" which makes it format XML
832 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
833 JSONText in ECMA-262) is JSONValue, not JSONObject.
837 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
838 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
840 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
841 POSIX/Unix builds .so with major version 4.
843 Remove old LOG_-defines from log.h. They have been obsolete and
844 undefined by default for the last 5 years.
846 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
848 GFS: Remove socket (int *fd) from search_rr handler. The socket
849 descriptor ptr is a facility that allowed a search handler to supply
850 a socket which would serve as a callback - when search was complete.
851 This facility has now been in use for years.
853 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
854 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
855 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
856 returns 'const char *' rather than 'char *. The returned string is
857 read-only and should not be modified by applications. COMSTACK cs_close is
858 now a void function - it no longer returns int. No applications check for
859 the value and the implementations has always returned 0.
861 ZOOM: use size_t for scan hit counts and str size. Functions
862 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
863 occ (hit count) and len (string length) are now of type size_t pointer
864 rather than int pointer. This is to be able to represent large hit counts
865 and to also just to use the proper type for string length (strlen result).
867 New JSON parser. Refer to include/yaz/json.h .
869 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
870 Used to be int in some cases. Many wrbuf_-functions used to return an int
871 indicating some length.. These return values were never used. And so they
874 ODR: odr_malloc, odr_total now takes size_t for size.
876 clone_z_type: fix leak; occurred for encoding failures.
878 --- 3.0.52 2009/12/03
880 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
881 bug was introduced in 3.0.51.
883 --- 3.0.51 2009/12/02
885 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
887 tcpip comstack: fix leak for getaddrinfo.
889 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
890 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
891 Decoding of SRU "path" database is performed by private function
892 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
893 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
895 yaz-client: honor base command for SRU. Change when database setting
896 is applied for SRU and ensure it is kept when a connection is reset.
897 Change also the way errors are displayed or SRU (decoding of packages).
899 --- 3.0.50 2009/11/02
901 Add support for extra request / response data for SRU codecs and GFS.
902 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
903 for extra data response buffer and length. For the GFS, both request
904 and response data (XML) is carried in extra_args and extra_response_data
905 for the search handler. Patch by Ko van der Sloot.
907 ZOOM: For queries that cannot be converted to the specified rpnCharset,
908 ZOOM now returns a diagnostic on the client-side ('invalid query' /
909 10010). This fixes bug #2113.
911 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
912 cmdfile included a 'quit' command that would result in a memory violation.
914 --- 3.0.49 2009/10/01
916 Make a number of functions defined in xmlquery.c static. These have
917 never been declared in a public header file (yaz/xmlquery.h) and was
918 made public by mistake.
920 Improve speed of character conversions (iconv utilities). This makes
921 conversions from MARC-8 faster.
923 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
924 unless type desired is "raw". This will prevent type "xml" from
925 returning ISO2709 .. Which obviously can not be XML parsed.
927 Fix memory leak in ZOOM that would occur if option apdulog was used
928 on a re-used connection.
930 Frontend server logs HTTP requests.
932 Frontend server now sends Z39.50 close when it times out (sesssion has
933 been idle for too long). Versions 2.0.30 and earlier also sent close.
934 But due to a mistake this was disabled in all versions after that, i.e.
935 the server would just close the socket immediately.
937 yaz-client emits a better message when receiving an unrecognised
938 userInformationField.
940 Skip zero-length subfields when decoding ISO2709. This rare case happens
941 if a record has two FS characters in a sequence. Without this patch
942 there would be a reference beyond char array in using_code_len fragments
945 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
947 --- 3.0.48 2009/08/28
949 The show command offered by the zoomsh command now takes a 3d optional
950 parameter type which is what is passed to ZOOM_record. If the type
951 argument is omitted, "render" is used.
953 RPN to CQL conv may use USE string attributes (bug #2978).
955 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
957 --- 3.0.47 2009/07/08
959 Function yaz_xml2query allows a diagnostic element in the PQF XML
960 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
961 code and additional info respectively.
963 The BER BOOLEAN is now the integral type Odr_bool which still happens
964 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
965 typedef'd to Odr_int. This is still an integral 'int', but it may be
966 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
967 ASN-1 compiler as well as programs has been updated to use the new types.
969 --- 3.0.46 2009/06/08
971 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
972 only the bibliographic record was rendered. For type=opac, an OPAC
973 record is only returned if it is present.
975 iconv: small fix for encoding of advancegreek.
977 yaz-client: avoid double display of SRU/SRW records (bug #2798).
979 yaz-client: option auto_reconnect=on really reconnects.
981 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
983 server: avoid null ptr ref for for yaz_poll errors.
985 build: fix RPM build for RHEL 5.3.
987 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
989 --- 3.0.45 2009/03/31
991 Fixed bug #2709: TCP connect returns Invalid argument.
993 Fixed compilation for mingw.
995 Honor charset for raw records (ZOOM_record_get).
997 Fixed use of errno for threaded mode that was seen on Solaris 10.
999 Fixed argument passing with blanks in value for Windows Service.
1001 Disable YAZ' own log rotate by default (no 1 GB limit).
1002 The variable l_max_size which specifies the log file limit is set to 0
1003 (DISABLED): This is due to the fact that YAZ is most often deployed using
1004 logrotate. Also YAZ can not perform log rotate because of unsufficient
1005 permissions (setuid).
1007 --- 3.0.44 2009/02/17
1009 List supported encodings in man page for yaz-iconv.
1011 Fixed missing SSL libs for --libs output
1013 Re-established OID record syntax application-xml. Nobody should use it
1014 but we don't want to change soname because of this symbol being absent.
1016 --- 3.0.42 2009/02/02
1018 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1020 Added member named_result_sets for init handler struct for the GFS. This
1021 allows a server to disable named result sets.
1023 Removed OID record syntax application-xml.
1025 Added support for rule-based transliterator for ICU wrapper of YAZ.
1027 Fixed bug #1902: yaz-icu XML output.
1029 Make YAZ checks Emacs friendly.
1031 BITSTRING value shows value. Bug #2346.
1033 ISO2709 decoding: skip control characters from indicator data.
1035 Omit sort key by default in yaz-icu's output.
1037 Allow combined single char options (again) for YAZ' options function.
1039 Utility yaz-marcdump got option to display YAZ version (-V).
1041 Allow YAZ to use ICU 3.4.
1043 Added new ICU test case which illustrates removal of diacritics.
1045 --- 3.0.41 2008/12/29
1047 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1049 --- 3.0.40 2008/12/29
1051 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1054 Fixed bug #2352: yaz-marcdump crashes for certain record.
1056 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1058 Added support for Danmarc2 to UTF-8 conversion.
1060 Added support for ISO5426 to UTF-8 conversion.
1062 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1063 implementation version.
1065 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1067 --- 3.0.38 2008/11/10
1069 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1070 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1072 ZOOM C now interprets databaseName option for ZOOM connection as path
1075 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1077 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1079 Dummy Libxml2 types no longer defined in headers of YAZ'.
1081 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1084 --- 3.0.36 2008/09/26
1086 Various ODR chapter fixes.
1088 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1090 Added missing source for Windows compilation, mutex.c.
1092 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1094 For SRU connections in ZOOM all records up to "count" are now fetched.
1096 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1097 in Windows due to bad error handling for Libxml2.
1099 Added facility for sending arbitrary records (ASN.1 any) using
1100 ZOOM C's Extended service update. Patch by Sam Reynolds.
1102 New options for ZOOM C's connection, logapdu which makes ZOOM log
1105 --- 3.0.34 2008/06/18
1107 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1109 --- 3.0.32 2008/06/12
1111 Fixed memory violation that could occur when decoding UTF-8. This bug
1112 was only present in 3.0.30 of YAZ.
1114 --- 3.0.30 2008/06/06
1116 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1117 GNU TLS is used by default (if found).
1119 yaz-ztest returns OPAC records if a client asks for OPAC.
1121 Improved speed of MARC-8 encoding.
1123 Added support for lossy and loss-less MARC-8 encoding.
1125 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1127 Added new Windows Service wrapper (sc).
1129 yaz-client's itemorder command may now send a file.
1131 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1133 Added new function yaz_log_xml_errors.
1135 Allow (but warn) unknown XML attributes in MARCXML parsing.
1137 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1139 The UTF-8 to MARC-8 conversion now uses a different set of characters
1140 for Greek symbols. Bug #2120.
1142 --- 3.0.26 2008/02/21
1144 Added yaz_daemon (daemon.h).
1146 Fixed bug #2068: pkg-config trouble
1148 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1150 --- 3.0.24 2008/01/28
1152 Document --with-xml2 option.
1154 Added OPAC XML XSD (etc/opacxml.xsd).
1156 Allow glob mask for name attribute in retrieval element for the
1157 generic frontend server's retrieval facility.
1159 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1160 except POLLIN/POLLOUT.
1162 Fixed error handling in cs_listen. Bug #2037.
1164 --- 3.0.22 2008/01/20
1166 Fixed version in yaz/yaz-version.h.
1168 Fixed bug #2027: Crash when closing connection.
1170 Changed configure so that ICU support is only enabled if only ICU
1171 and Libxml2 is available (because the ICU chain is XML based).
1173 --- 3.0.20 2008/01/15
1175 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1176 is built. Only this DLL depends on the ICU runtime.
1178 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1179 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1181 Changed license of CCL module to 'Revised BSD'. After consultation with
1182 remaining members of the original EUROPAGATE consortium, we are re-issuing
1183 the CCL module without a separate license. The software was developed by
1184 Index Data as part of a research project. The special license was included
1185 to help feed usage information back to the project consortium to support
1186 project evaluation. At this time, the project consortium has long-since
1187 disbanded, and the majority of the original principals have retired. At the
1188 same time, we have significantly modified the software during the following
1189 years, to the point where very practically no original code remains. To
1190 simplify re-use of the software, we have contacted those members of the
1191 consortium who could be reached, and agreed to re-issue the module as a
1192 proper part of the YAZ package.
1194 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1196 CQL closer to being version 1.2 compliant. CQL also allows free-form
1197 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1200 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1201 bug could make Extended services handling crash in the ZOOM layer. This
1202 bug was only present in YAZ 3.0.18.
1204 --- 3.0.18 2007/12/19
1206 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1209 yaz-marcdump reads and writes collection wrapped records.
1211 Handle OPAC for record conversion module.
1213 Fixes for ICU wrapper.
1215 Allow ICU libs to be controlled with --with-icu .
1217 --- 3.0.16 2007/11/12
1219 Added yaz_poll which is a wrapper for select/poll. When poll is available
1220 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1221 sockets to be in use.
1223 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1224 functionality through an XML based configuration (ICU chain). This system
1225 is useful for search facilities such as Pazpar2 and Zebra that needs to
1226 perform tokenization of indexed material. The ICU code in a separate
1227 library libyaz3_icu.a.
1229 Added HTTP tunnel facility for COMSTACK, bug #1752.
1230 This is a facility that allows a Web proxy, such as squid, to tunnel
1231 Z39.50 traffic. This facility is "transparent" to must applications
1232 using YAZ. It's enabled by using pseudo transport connect: followed by
1233 the proxy address, followed by command, then follwed by he regular
1234 "virtual" addresss. For example,
1235 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1237 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1239 --- 3.0.14 2007/09/21
1241 Fixed bad memory reference in ZOOM_record - cuased by member not being
1242 initialized. This was a problem only in YAZ 3.0.12.
1244 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1245 fields were not removed.
1247 Changed the way C code is generated from codetables.xml. Made a MARC-8
1248 conversion trie for each characterSet section rather than codeTable.
1249 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1250 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1252 --- 3.0.12 2007/09/12
1254 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1255 from ZOOM_record_error).
1257 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1259 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1261 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1263 Better SRW-to-Bib-1 diagnostic mapping.
1265 ZOOM C and yaz-client announces SRU version 1.2 by default.
1267 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1270 Fixed in yaz_sru_decode to allow other version than 1.1.
1272 --- 3.0.10 2007/08/22
1274 Added support for SRU scan for ZOOM.
1276 Added support for the use of the older versions or Extended Service
1277 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1278 set to the version , 1=first, 2=second, 3=third. The third version is
1279 what ZOOM C has used so far. And that, obviously, is the default.
1281 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1282 therefore in Zebra and in SimpleServer-based applications). The new
1283 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1284 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1285 which is passed into the back-end search callback function.
1287 Added support for HTTP Basic authentication in clients: the SRU/W
1288 codec encodes the username/password elements of the PDU structure
1289 appropriately, and these may be set using the "user" and "password"
1290 options in ZOOM-C applications (the same options that are used for
1291 Z39.50 authentication).
1293 --- 3.0.8 2007/06/25
1295 Fixed bug #1208: SSL appears to be broken in ZOOM.
1297 Fixed bug #1206: Libxml2 include path weirdness.
1299 Added oid_name_to_dotstring.
1301 Allow elementSetName to be specified for ZOOM C record update.
1303 Allow waitAction to be specified for ZOOM C based for Extended Services.
1305 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1306 syntax OID. Bug introduced in YAZ 3 series.
1308 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1310 --- 3.0.6 2007/06/06
1312 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1313 directory. yaz-client now reads commands from file given by option -f
1314 if specified; then tries to read .yazclientrc in current directory.
1315 Failing that, it reads .yazclientrc from user's home directory.
1317 Added support for correlationInfo Note and ID for Record Update via
1320 Added yaz-client command querycharset which specifies character set for
1321 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1322 (termListAndStartPoint).
1324 Charset ISO5428:1984 is an alias for ISO5428-1984.
1326 Implemented a way to perform scan in a result set using Z39.50. This
1327 is achieved by attaching the result set name in the characterInfo
1328 (type InternationalString) of OtherInformation in the Scan Request PDU.
1329 The result set is identified in the otherinformation by the new OID:
1330 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1331 This allows for scan in result set and faceted search . Zebra did some
1332 of this in the APT term using attribute type 8 and value being result
1333 set. Using the OtherInformation approach for this is cleaner and easier
1334 to work with in proxies and the like. This facility can be used in
1335 yaz-client using new command setscan which takes a result set as first
1336 argument, start position (APT) as second.
1338 Changed decoding of SRU XML packed records to deal with servers that
1339 have recordData with XML data with multiple root nodes. Also make
1340 comparison for recordPacking case insensitive. Again, one server
1341 returns "XML" where others return "xml".
1343 For SRU responses allow Content-Type application/xml as well as text/xml.
1345 --- 3.0.4 2007/05/21
1347 Fixed bug in character set conversion of BER strings. Bug introduced
1350 --- 3.0.2 2007/05/08
1352 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1354 For OID class, use oid_class consistently.
1356 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1359 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1360 character set for bibliographic information interchange". By Giannis Kosmas.
1362 Added documentation on new OID API.
1364 --- 3.0.0 2007/05/02
1366 Changes to generic frontend server interface: added new member
1367 'query_charset' for bend_initrequest structure. A backend init handler
1368 should set this member to its native character set for query terms.
1369 When defined, the frontend server logic will announce this character set
1370 to a client if the negotiationModel bit is set by the client. All server
1371 implementors are encouraged to specify this. If a backend server does not
1372 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1374 Added CCL utility to remove terms (stop words) from resulting RPN
1375 tree. This is handled by functions with prefix ccl_stop_words_ .
1377 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1378 terms in RPN queries.
1380 Clean-up the CCL API. Moved some internal structures from ccl.h to
1381 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1382 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1383 This is replaced by ccl_parser_find_str which takes a string instead.
1385 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1386 libyaz.la is the core of YAZ except the generic frontend server and
1387 does not depend on POSIX threads anymore. libyaz_server.la is the
1388 generic frontend server facilities and uses POSIX thread functionality
1389 if available. The libyaz.la no longer depends on POSIX threads because
1390 the number of global structures is limited. NMEM no longer re-uses blocks
1391 between threads ; it simply free's memory immediately but allocates in
1392 "large" chunks as usual. We don't expect any performance penalties
1393 because of this. The yaz_log system is still using a global log_level so
1394 caution must be taken when modifying it with yaz_log_init_.. +
1395 yaz_log_mask_str. This, however, should not cause any trouble because
1396 these functions are called during initialization of application code
1397 anyway. `yaz-config --libs server` returns libs for server applications;
1398 `yaz-config --libs` returns libs for non-server applications.
1400 New OID database - with public definitions in oid_db.h. Removed old OID
1401 database including the head oid.h and definitions such as enum oid_value
1402 and struct oident. The new OID database uses the same string names as
1403 before but the 'protocol' is gone. There are now only two representations
1404 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1405 converts from string to OID; functions with prefix yaz_oid_to_string
1406 converts the other way.
1408 Change to emit_term() in CQL-to-PQF query translation: when a term has
1409 the /regexp relation modifier, do not process it for leading and
1410 trailing "^" and "*", which have quite different meanings in regular
1413 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1414 write handlers no longer carries a 'last' parameter. This will make
1415 yaz_iconv flush "less" characters. A flush is performed by call to
1416 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1418 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1419 removed, because function yaz_query_to_wrbuf does the same.
1421 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1422 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1424 Deprecated MARC utility functions removed.
1426 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1429 Branch split: YAZ_2_1_55_branch
1431 --- 2.1.54 2007/03/16
1433 Fix to ZOOM-C so that transparent reconnection is properly handled on
1434 connections that are in asynchronous mode.
1436 Fixed compilation on OpenBSD 4.0.
1438 Large strings in GRS-1 records are now properly displayed in yaz-client.
1440 Added character conversion support for "advancegreek"; based on patch from
1443 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1444 sequence is met. Before the error was not set so it would be unknown.
1446 Adjust yaz-marcdump MARC reader so that it skips until record separator
1449 --- 2.1.52 2007/03/07
1451 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1452 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1453 fd_set structure used as a bitmask for the FDs to be selected on.
1455 Using ACX_PTHREAD macro to check for POSIX threads.
1457 Fixed have-vsnprintf check.
1459 --- 2.1.50 2007/02/23
1461 Fixes for configure on BSD. Bug #900.
1463 Added snprintf/vsnprintf wrappers for systems that don't have
1464 limits (heavens forbid).
1466 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1467 created before all previous tasks were completed and removed from the
1468 task queue, the new task could be removed by a mistake.
1470 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1472 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1474 Fixed bug #832: Problem with MARC/charset in yaz-client.
1476 Fixed bug #668: save command line history for yaz-client.
1478 Fixed bug #830: pkg-config support.
1480 --- 2.1.48 2007/01/23
1482 Extended ZOOM result set options with two options that may be read by
1483 a client: resultSetStatus and presentStatus with values as specified for
1485 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1487 Fixed bug #827: Using SSL fails on Debian etch.
1489 Fixed bug #826: Weird looking chars for set of MARC records.
1491 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1492 that is treated as an ItemOrder with itemRequest being an XML document
1493 external. The value of "doc" is the content.
1495 Extended the GFS search facility. New member of bend_search_rr
1496 'estimated_hit_count' signals that hits is known to be an estmate
1497 (higher or lower than real hit count). New member 'partial_resultset'
1498 signals that the search was partial (hit count is lower or equal than
1499 real hit count). For Z39.50, the information is stored in resultSetStatus
1500 member of SearchResponse APDU. For SRU, the information is signalled
1501 via SRU diagnostic 59: "Result set created with valid partial results
1504 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1506 --- 2.1.46 2007/01/13
1508 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1510 Added ZOOM_connection_peek_event.
1512 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1513 the following new functions:
1514 ZOOM_event_nonblock, ZOOM_connection_process,
1515 ZOOM_connection_get_{socket,mask,timeout},
1516 ZOOM_connection_fire_event_{timeout,socket}.
1517 The existing blocking event handler, ZOOM_event, is a wrapper for the
1518 + blocking ZOOM_event_sys_{poll,select}.
1520 Implemented function ccl_xml_config which parses XML version of CCL
1521 configuration (bug #798).
1523 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1525 Added timings utility (yaz/timing.h)
1527 --- 2.1.44 2007/01/03
1529 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1532 Fixed bug #779: Rotation of apdu.log fails.
1534 Fixed for character set conversions:
1535 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1536 Honor G1 set in MARC-8 decoding.
1538 --- 2.1.42 2006/12/17
1540 Fixed bug #775: char conversion does not handle Alternative UTF-8
1543 Implemented function yaz_marc_read_line which parses MARC line format
1544 records. There is a wealth of formats out there. So far, this function
1545 reads line records produced by yaz_marc_write_line.
1547 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1548 more generic and easier to remember(!) options: -i format and -o format
1549 which specifies input format and output format respectively - where
1550 format is one of "marc", "marcxml", "line", "marcxchange".
1552 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1553 does not print anything except warnings for records.
1555 For yaz-marcdump, added support for MARC split into files (-s) with a given
1558 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1559 spec, at http://www.loc.gov/standards/sru/record-update/
1560 This has changed the binary layout of the following structs:
1561 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1562 bend_update_rr . Patch by Ko van der Sloot.
1564 Added GFS utility function bend_assoc_is_alive which returns 1 if
1565 association is still alive (client is connected); 0 otherwise (client
1566 closed connection). This allows busy servers to stop working for
1569 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1570 been a separate piece of software. This version of ziffy has been modified
1571 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1573 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1575 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1576 Client code may now interrogate options such as "init_opt_sort" to
1577 find out whether the server claims to support various options.
1579 --- 2.1.40 2006/11/27
1581 Added utilities yaz_{set,get}_esn to set/get element set name from
1584 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1585 of YAZ and has been so since YAZ 2.1.10.
1587 Implemented ZOOM_record_error which returns error information for
1588 record (surrogate diagnostic).
1590 --- 2.1.38 2006/10/31
1592 Updates for SRU Update by Ko van der Sloot:
1593 1. Changed name from "operation" to "action"
1594 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1595 versions in the code, marked as 'backward compatible'.
1596 3. Added diagnostics for SRU Update.
1598 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1600 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1602 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1604 For GFS, fixed problem with SRU diagnostic 'First record position out of
1605 range' being issued for 0 hits.
1607 zoomtst10 part of Windows Build.
1609 --- 2.1.36 2006/10/13
1611 Implemented yaz_filepath_comp which splits a path into file path
1612 components (required by Zebra 2.0.3+).
1614 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1615 BSD inspired license until now so this should not have any real impact on
1616 anybody. See http://www.opensource.org/licenses/bsd-license.php
1618 Fixed bug #687: Missing log lines.
1620 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1623 Fixed bug #689: SRU diagnostics to be added.
1625 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1626 whether a connection is idle (no more work do do).
1628 --- 2.1.34 2006/10/04
1630 Change type of optval from long to int for invocation of setsockopt with
1631 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1633 Added support for specifying the max log file size for the Generic
1634 Frontend Server. The size is given with option -r.
1636 --- 2.1.32 2006/09/21
1638 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1640 --- 2.1.30 2006/09/17
1642 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1645 Fixed bug in Generic Frontend Server that could cause a server to stop
1646 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1648 For the generic frontend server, the maximum record size is used as maximum
1649 size of incoming packages (SRU + Z39.50). The value until was previously
1650 only used in Z39.50 Init negotiation and, later, in a session controlled
1651 sizes of records returned. This is controlled using -k option. It can be
1652 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1654 --- 2.1.28 2006/09/04
1656 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1659 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1661 New option for yaz-marcdump -lpos=value which allows setting a portion
1662 of MARC header to a certain value.
1664 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1666 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1667 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1669 --- 2.1.26 2006/08/15
1671 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1674 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1676 --- 2.1.24 2006/08/08
1678 Fixed MARC ISO2709 encoding routines to deal with character set
1681 Minor changes to GFS logging. Database included in search request log
1684 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1685 cached/multiple records.
1687 Shared libraries are built by default on Unix+configure.
1689 Changed cql2pqf transformation to use a different evaluation order. The
1690 new order is: always, relation, structure, position, truncation, index
1691 and relationModifier. Old order was: always, relation, relationModifier,
1692 structure, index, position, truncation. Note that the the latter ones
1693 override former ones for identical attributes.. The new scheme means that
1694 it is possible to override any existing attribute with a relationModifier.
1695 And also that it is possible to override everything for the index rule
1696 (except the ones listed in relationModifier). No order is perfect but this
1697 one, we believe, covers more real cases.. The "always" should have been
1698 called "default", since the attributes there can be overridden with all
1701 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1702 compilation phase, but also for yaz-config --cflags output. This allows
1703 us to have public headers with Libxml2 stuff in them . It should also,
1704 eventually, make Libxml2 checks redundant in packages using YAZ, such
1707 --- 2.1.22 2006/06/15
1709 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1710 stored in uri, message and details.. Previously diagnostics were stored
1711 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1712 compatibility.. but he's probably the only one affected, so.
1714 Added support for CCL, compiled on the client side, in ZOOM-C. This
1715 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1716 input; the resulting query objects can be used for for searching with
1717 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1719 YAZ' configure searches for OpenSSL by default.
1721 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1722 SL_CTX_use_certificate_file. See
1723 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1724 for more info. Thanks to Ko van der Sloot.
1726 --- 2.1.20 2006/06/02
1728 Bug #600: SRU GET, POST support for yaz-client. Introduced
1729 command 'sru' which selects method SOAP/GET/POST.
1731 Allow missingValueAction to be specified for the sortspec string -
1732 function yaz_sort_spec. By default, the missing value action is null.
1733 Use ! to specify "abort". Use = followed by stringvalue to specify default
1736 Ensured that Present-handler (if defined) is called in GFS before any call to
1737 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1738 searchRetrieve requests.
1740 Documentation for YAZ is now based on the Docbook XML/XSLT using
1741 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1742 is no longer depending on jade/openjade or docbook-to-man scripts.
1743 PDF is no longer part of the distribution - but can optionally be
1744 made using DSSSL/jadetex or FOP.
1746 Added retrieval handling support in Generic Frontend Server to support
1747 conversion between MARC/XML as well as XSLTtransforms. See
1748 etc/yazgfs.xml for an example.
1750 Added Authentication support to Generic Frontend Server in SRU
1751 mode. Authentication using HTTP Basic is supported, as is the use
1752 of 'x-username' and 'x-password' parameters in the request itself.
1754 Added support for a new character set MARC8s identical to MARC8 except
1755 that it converts combined characters to single Unicode characters in the
1756 Latin-1 range (when possible).
1758 --- 2.1.18 2006/04/24
1760 ASN.1 compiler 0.4: generates brief Doxygen file header for
1761 generated .h/.c files.
1763 Utility yaz_iconv now supports conversion to MARC-8.
1765 New facilities for the MARC module. The reading - and writing of
1766 content are separate methods for the yaz_marc_t handle. The following
1767 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1768 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1769 format). Write functions have prefix yaz_marc_write_.. The existing
1770 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1771 available. Removed support for OAI-MARC and simplexml (not the
1772 simplexml from PHP5).
1774 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1775 to be returned for this connection.
1777 --- 2.1.16 2006/03/31
1779 Allow multiple languages and charsets to be specified with
1780 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1781 negcharset iso-8859-1,utf-8
1783 Translation of proximity nodes from CQL into PQF now works.
1785 Moved to automake 1.8, 1.9.
1787 Added function yaz_log_set_handler which allows a log handler to be
1788 installed. This handler will be called for all log messages. Output
1789 to file is also produced; but that can be disabled by passing NULL
1790 fname to yaz_log_init_file.
1792 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1794 For SRW (including GFS), accept application/soap+xml as content-type
1797 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1798 produces NO stylesheet reference even if a default stylesheet is specified
1801 --- 2.1.14 2006/03/14
1803 Updated Windows package to include yazd.dll + yazd.lib for the
1804 Development component.
1806 If the environment variable YAZ_LOG is set, then it is used as a
1807 string indicating the default level of logging to use if not
1808 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1809 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1810 used as before. So, for example, to omit warnings from YAZ logging,
1811 export YAZ_LOG=-warn
1813 cql_transform() now map structure and other attributes before indexes,
1814 so that index-specific structures and other attributes can override
1815 defaults. So now a combination of mapping specifications such as:
1817 index.dc.date = 1=date-modified 4=5
1818 does the right thing.
1820 cql_transform() now also respects the "always" mapping specification,
1821 which establishes an initial set of attributes to be used for all
1822 terms except where overridden by more specific attributes associated
1823 with the index, relation or modifier.
1825 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1826 which mode to use; one of "post", "get" or "soap" (SRW, default).
1828 Fixes for yaz_iconv routines: changed trie-based character set conversions
1829 to use only non-negative values for bit fields due to Sun's C compiler not
1830 supporting negative values.
1832 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1833 sequences where not read correctly. Fix by Rustam Usmanov.
1835 Updated win/makefile to use options, settings which makes things
1836 compile with VS C 2005.
1838 --- 2.1.12 2006/02/01
1840 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1842 In ZOOM socket code, use select instead of poll on MacOSX.
1844 ZOOM-C now support client-side compilation of CQL into RPN that is
1845 sent to the server, enabling CQL to be used against all Z39.50
1846 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1847 ZOOM_query object, and submit it using ZOOM_connection_search().
1848 The CQL-to-RPN translation uses a configuration file, the name of
1849 which must be specified in the Connection's "cqlfile" option.
1851 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1852 function, which takes as its start-term parameter a ZOOM_query object
1853 (which may have had either CQL or RPN set into it).
1856 --- 2.1.10 2005/11/29
1858 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1859 GFS to support this as well. Backend handler, bend_srw_update, does the
1860 update work. Code contributed by Ko van der Sloot.
1862 Allow retrieval of Search Result-1 information in ZOOM by the use of
1863 options that are attached to a result set. ZOOM documentation updated
1866 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1867 UTF-8 conversion. Patch by Raj Patel.
1869 Added option -m to GFS to control formatting of timestamps in log file.
1871 Added 'exit' as synonym for 'quit' in yaz-client
1873 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1874 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1875 for the new members. Patch by Ko van der Sloot.
1877 Added support for SRU POST. It is supported for content-type
1878 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1880 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1881 Instead make the library libyaz.la multi-threaded. Threading as a whole
1882 can still be disabled by configure option --disable-threads. Previosly,
1883 with older GLIBCs there were problems with MT libs under Apache. This
1884 has now been fixed a long time ago.
1886 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1889 CQL module modified to be case insensitive for relations/indexes/operations.
1891 Fixed bug in CQL transform code: incorrect value relationModifieder
1894 Added 'show all' command for yaz-client which retrieves all results
1897 Added new yaz-client, xmles, which takes a (private) OID and
1898 a document to be sent as an extended service request.
1900 Describe new yaz-client commands wait_response and set_auto_wait.
1902 Increase TCP/IP listener backlog from 3 (which I am guessing was
1903 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1904 that the socket will queue as many incoming connections as it's able
1905 to handle ongoing connections. In other words, it will never now
1906 refuse a connection that it would be able to handle merely because
1907 it's not got around to accepting() enough of the pending connections
1908 yet. This is the behaviour anyway under Linux, where the listen()
1909 argument is ignored; but not under BSD and on systems such as
1910 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1911 YAZ-based servers should now be uniform across operating systems in
1914 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1915 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1916 This allows yaz-marcdump to read large MARC batches (>2 GB).
1918 Modified all YAZ source files - except the source which is auto-generated
1919 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1922 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1923 corresponding to the existing *_setl() function. These allow option
1924 values containing arbitrary valuues.
1926 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1927 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1928 except that it returns an indicator of whether or not the sort
1929 criterion was accepted (0 for OK, -1 for invalid).
1931 --- 2.1.8 2005/06/07
1933 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1934 MARC output rather than returning "new" buffer.
1936 yaz-client warns about unknown init options.
1938 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1940 --- 2.1.6 2005/05/24
1942 Added support for SRW sort in Generic Frontend Server. Patch
1943 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1944 sortKeys - or NULL if none is provided.
1946 Fixed bug #307: It was impossible to specify indefinite/no timeout
1947 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1950 Added support for multiple languages and charsets to be specified in
1951 ZOOM. Each charset/language is separated by a blank. If negotiation is
1952 in effect in init-response, Option
1953 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1954 Code based on patch by Vasiliy Osadchuk.
1956 Fixed bug #306: infinite recursion that occurred when calling
1957 yaz_log_level_init as the first call (before other log level or
1960 Fixed bug in scan handling in front end server: if preferred-Position-In-
1961 Response was non-present, a NULL pointer referece was performed.
1963 --- 2.1.4 2005/04/26
1965 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1966 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1967 now defined for all those error codes. So instead of putting 109 in
1968 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1969 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1971 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1974 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1976 Program yaz-client now exits and produces an error message if multiple
1977 Z39.50 servers are specified on the command line (none or one allowed
1980 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1983 --- 2.1.2 2005/03/16
1985 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1987 Fixed bug #272: Preserve spacing for CCL terms.
1989 --- 2.1.0 2005/03/14
1991 Added support for virtual hosts and multiple backend servers for
1992 the YAZ frontend server. The configution is XML based and
1993 support specificition of CQL to RPN mappings and explain information.
1994 See section "Virtual Hosts" in the YAZ manual.
1996 Extended OPAC display utility. OPAC display utility renders
1997 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1998 to supplement yaz_marc_decode_wrbuf.
2000 Fixed a bug in MARC decoder that could caused it to crash for some
2001 invalid MARC records. More diagnostics and warnings where added in
2002 XML output (warnings, etc are stored in comments).
2004 --- 2.0.34 2005/02/08
2006 Fixes for UNIX domain sockets. Bug #261.
2008 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2010 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2011 Added yaz_marc_subfield_str which defines subfield lead string which is
2012 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2013 yaz_marc_endline_str which defines end of fields string used in
2014 YAZ_MARC_LINE format. Default string is newline.
2016 Experimental support for MarcXChange. This format can be produced
2017 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2018 http://www.bs.dk/standards/MarcXchange.xsd
2020 Added yaz-client commands scansize that sets maximum number of
2021 entries to be returned by scan.
2023 --- 2.0.32 2005/01/11
2025 Added support for SRW scan in yaz-client and Generic Frontend Server.
2027 * Added whereInList member to SRW Scan Term.
2029 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2031 Fixed NMEM system to return aligned blocks on the smallest boundaries
2032 that are suitably aligned for all possible types on the particular
2033 architecture YAZ is being built for.
2035 --- 2.0.30 2005/01/04
2037 Fixed numerious warnings that was issued with newer versions of GCC.
2039 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2040 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2043 Make YAZ Generic Frontend Server slightly faster.
2045 Enhance (and reduce) logging for Generic Frontend Server.
2047 Revert YAZ log system so that it flushes every write operation
2048 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2050 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2051 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2052 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2053 will effectively disable old definitions.
2055 --- 2.0.28 2004/11/09
2057 Added yaz_log_time_format which specifies log format using
2060 Added yaz_log_module_level which returns mask for a module. Value
2061 is non-zero mask a if module is enabled; zero if disabled.
2063 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2064 in include/yaz/cql.h.
2066 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2068 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2070 Fixed bug #172: RPM builds does not enable SSL.
2072 Doxyfile.in part of dist. Doxyfile generated by configure.
2074 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2075 are given and the corresponding component does not exist.
2077 Extend CCL documentation in YAZ reference. Describe r=r.
2079 --- 2.0.26 2004/10/01
2081 Fixed MARC->MARCXML conversion to properly deal with
2082 fields, subfields, indicators having non-ASCII characters.
2084 Fixed MARC->MARCXML conversion so that ASCII control characters
2085 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2088 Added YAZ GFS support for conversion from Z39.50 surrogate
2089 diagnostics to SRW surrogate diagnostics.
2091 Bug fix: YAZ GFS did not return schema in explainResponse.
2093 --- 2.0.25 2004/09/30
2095 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2096 now converts recordSchema to elementSetName as well as schema URI.
2098 Fixed bug in COMSTACK that prevented HTTP request packages from being
2101 --- 2.0.24 2004/09/29
2103 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2104 does not require white-space before and after the dash in a range, e.g.
2105 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2108 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2109 due to new GCC removing "redundant" code.
2111 Added yaz-client commands scanpos and scanstep that sets preferred
2112 position and step-size for scan.
2114 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2116 Added CCL utility ccl_qual_buf which parses one or more CCL
2117 spec lines in a buffer.
2119 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2120 of name and value - ignoring empty lines and comments.
2122 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2124 Added odr_get_element_path which returns current element path for an
2125 ODR handle. This utility is useful in error handling or user-defined
2128 Added ODR_PRINT utility odr_set_stream which is is a more generic
2129 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2130 to a write function and pointer to close function. The close function - if
2131 non-NULL - will be called during odr_destroy.
2133 Fixed bug in CCL parser where truncation char was not removed from
2134 right side when truncation=both was in effect.
2136 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2139 --- 2.0.23 2004/08/11
2141 Fix buffer overrun in CQL parser when dealing with proximity (%).
2143 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2144 to UTF-8/UCS conversion is now only based on codetables.xml.
2146 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2148 --- 2.0.22 2004/08/06
2150 Add support for more "commit changes" in ZOOM (uses Extended Services).
2152 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2155 Yet another small fix for configure of SSL.
2157 --- 2.0.21 2004/05/14
2159 Fix SSL libs for configure when --with-openssl=DIR is given.
2161 --- 2.0.20 2004/05/10
2163 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2165 SSL comstack now uses yaz.pem certificate file on server side
2166 by default. Certificate filename can be configured by calling
2167 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2169 Fix bug regarding multiple calls to ZOOM_connection_connect.
2171 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2173 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2174 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2176 ZOOM now allows inspection of X509 peer certificate for verification.
2177 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2179 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2180 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2181 as "modular" but it simplifies things.
2183 Added cs_get_peer_certificate to that returns peer X509 PEM.
2185 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2186 NULL if SSL is unavailable.
2188 Documentation about MARC decoding tools.
2190 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2192 --- 2.0.19 2004/03/30
2194 Rename CHANGELOG to NEWS to follow GNU style packing.
2196 Fix bug with missing initialization of member in init_diagnostics.
2197 This bug affects threaded version of GFS server.
2199 --- 2.0.18 2004/03/20
2201 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2204 Ensure zlib.dll is packed with Windows install.
2206 --- 2.0.17 2004/03/17
2208 Fix encoding of xsd:string to use text instead of CDATA.
2210 Fix endless loop in CQL parser with unbalanced ".
2212 Use a more compact way to store MARC-8 conversion tables.
2214 --- 2.0.16 2004/03/16 Debian only
2216 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2219 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2224 --- 2.0.15 2004/03/01
2226 Another fix for decoding of XML packed records.
2228 --- 2.0.14 2004/02/25
2230 Fixes for Chunked encoding. White space not ignored after length spec.
2232 Update NS and use default NS for SRW diagnostic elements.
2234 --- 2.0.13 2004/02/23
2236 Implement ZOOM_resultset_cache_reset which resets record cache.
2238 Implement ZOOM_resultset_sort which sorts a result set.
2240 Implement chunked HTTP transfer.
2242 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2244 --- 2.0.12 2004/02/16
2246 Added member 'schema' to bend_explain_rr structure so that backend
2247 can specify explain record identifier. Defaults to Zeerex 2.0.
2249 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2251 --- 2.0.11 2004/02/16
2253 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2256 Added init command for yaz-client which sends "extra" init request.
2258 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2259 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2261 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2263 Make ZOOM error code for "invalid query".
2265 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2267 --- 2.0.10 2004/02/05
2269 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2272 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2274 Added option -p <file> to make Generic Frontend Server to write PID file.
2276 Added option -D to put Generic Frontend Server in background on its own.
2278 Make ZOOM C recognize option "password". If unset, "pass" is used
2279 (for backwards compatibility).
2281 Fixed a bug in Generic Frontend Server that could make it crash if a
2282 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2285 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2286 Must be issued before open, in order to be in effect.
2288 --- 2.0.9-6 2004/01/12 Debian/Windows
2290 Make the SRU server more picky WRT unknown params, etc.
2292 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2294 New YAZ client command, options, that sets Z39.50 options.
2296 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2297 options from a string of tokens (one token for each option bit).
2299 Update SRW diagnostic code messages.
2301 --- 2.0.9-5 2004/01/07 Debian/Windows
2303 Handle user defined stylesheet for SRW/SRU.
2305 --- 2.0.9-4 2004/01/06 Debian/Windows
2307 Fix bug in decoding of Content-Length.
2309 --- 2.0.9-3 2004/01/06 Debian/Windows
2311 Fix a bug with decoding of XML packed records.
2313 --- 2.0.9-2 2004/01/05 Debian only
2315 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2317 Fix bug in SRW/SRU diagnostics decoding.
2319 --- 2.0.9 2004/01/05
2321 Fixed bug in Generic Frontend Server which could drop records exceeding
2322 preferred message size. Reported and fixed by Irina Dijour.
2324 Fixed calculation of package size for structured records in Generic
2325 Frontend Server. Reported and fixed by Irina Dijour.
2327 Fixed namespace for SRW/SRU diagnostics.
2329 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2331 --- 2.0.8 2003/12/22
2333 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2334 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2337 CQL changes to reflect recent changes to the specification:
2338 * Documentation talks about context sets instead of index sets.
2339 * Documentation talks about indexes instead of qualifiers.
2340 * The CQL-to-PQF transformer's configuration file now uses
2341 "index.set.name = <attributes>" instead of the old form
2342 "qualifier.set.name = <attributes>". (Both forms are still
2343 understood but the latter is deprecated.)
2344 * CQL terms with no explicit index specified are now interpreted as
2345 cql.serverChoice instead of srw.serverChoice (which of course
2346 behaves exactly the same.)
2348 --- 2.0.7 2003/12/16
2350 MARC conversion can now generate ISO2709 output in another
2351 character set. yaz-marcdump uses this facility if you invoke it
2354 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2355 functions from there can be used from C++.
2357 --- 2.0.6 2003/12/04
2359 Frontend server now transfers memory from decoded packages to stream
2362 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2363 references to show up.
2365 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2366 the ZOOM Abstract API. The older names for the same options are still
2367 also supported for the benefit of old applications.
2369 ZOOM-C supports "implementationId" and "implementationVersion" options
2370 to go along with "implementationName". These allow the user code to
2371 specify identification strings to be sent to servers.
2372 Add OID for the new ExtLite attribute set.
2374 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2375 as requested/supplid by Ere Maijala <ere@atp.fi>
2377 For generic frontend server, reverse the order of
2378 "toolkit-supplied / application-supplied" strings sent as implementationId,
2379 Name and Version. Also, remove the spaces around the slash. This brings
2380 the GFS in line with the behaviour of ZOOM-C on the client side.
2382 Add function ZOOM_scanset_display_term.
2384 yaz-client shows scan displayTerm if present.
2386 Utility yaz-iconv is now installed by default along with the man page
2389 Extend configure check for OpenSSL to use pkg-config where available (such
2392 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2393 server to specify uid/gid/mask for socket using the format
2394 unix:[user=uid,][group=gid,][umask=mask,]file=path
2395 If file= is omitted the existing format is assumed, e.g.
2397 in which case the mask is 0666 (rw for everybody).
2399 Major restructure of YAZ source. All source in libyaz is in src directory.
2400 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2401 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2403 Added man page for utility yaz-marcdump (used to be called marcdump).
2404 yaz-marcdump is installed by 'make install'.
2406 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2407 of incoming package failed.
2409 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2411 Change prototype of odr_perror: add const to message string.
2413 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2415 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2416 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2417 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2418 DNS lookup. There should not be any compatibility problems with this
2419 assuming that blocking=1 or 0 is used.
2421 Fix bad reference in UNIX comstack in function cs_addrstr.
2423 Fix for compilation on AIX.
2425 The generic front-end server (server/seshigh.c) now supports returning
2426 Init diagnostics to the client in User-information-field, in
2427 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2430 --- 2.0.4 2003/09/04
2432 Allow any CQL relation (not just all,any,exact,scr).
2434 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2435 that features the same UI.
2437 Implemented command update0 in YAZ client which is equivalent to
2438 update but uses old of Ext Update ASN.1.
2440 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2441 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2442 Previously no OID was used for this info.
2444 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2445 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2446 returns 'malformed search term' otherwise.
2448 SortResponse member resultCount now set to NULL in sort handler of
2451 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2454 Add three new utility functions for translating OIDs between various
2455 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2456 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2457 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2458 char *oid_to_dotstring(const int *oid, char *oidbuf);
2459 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2461 Reverted modifications for ES Update definition for z_IU0Update
2462 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2463 is back to YAZ 2.0.2.
2465 String value attributes for CCL parser.
2467 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2468 which their FirstSearch server returns in Init responses, sometimes
2469 carrying useful diagnostic information when Init fails. This has the
2470 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2471 "z39.50/oclcui.asn", where its definition is somewhat different from
2472 what OCLC document on their web-site, as required to interoperate with
2475 Support for anonymous authentication in yaz-client. Use the command
2478 * Fix the OID of the Index Data-local "admin" Extended Service from
2479 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2480 the 1000, which indicates a locally-defined OID, was a mistake.
2482 --- 2.0.3 2003/06/20
2484 Fix CCL directive @case handling so that it affects string match for
2485 both CCL keywords and qualifiers.
2487 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2488 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2489 Decoder has been updated with ASN.1 changes as listed in
2490 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2491 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2492 z_IUUpdate, remains unchanged.
2494 ZOOM_record_get may now return a record in a specific character set.
2495 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2496 "from" is the character set of record as returned by target. "to" is
2497 the character set to be returned. If omitted, "to" is UTF-8.
2499 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2501 New ODR utility, odr_getelement, which returns name of element for
2502 which encoding/decoding failed.
2504 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2505 in cases where a required element was omitted.
2507 Bug fix: some MARC8 sequences were not converted.
2509 New ZOOM option "step" which specifies number of records to be
2510 retrieved in one chunk. Used in conjunction with "start" and "count".
2512 SRW support for yaz-client. Use scheme http: to use it, e.g.
2515 yaz-client no longer does (un)intelligent character set conversions
2516 by default. Can be enabled with charset and marc_charset commands.
2518 xmalloc trace fix for 64-bit systems such as DEC alpha.
2520 Solaris 2.6 compile fix.
2522 New function, cql_strerror() translates SRW error codes, as returned
2523 by cql_transform_error(), into human-readable English strings. Used
2524 in yaz-client diagnostics when appropriate.
2526 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2527 converts it into a type-1 query which is sent to the server. This
2528 makes CQL available for use with all Z-servers, as opposed to the tiny
2529 minority that can handle CQL queries themselves.
2531 --- 2.0.2 2003/04/28
2533 New Debian package layout similar to the Redhat Package layout.
2535 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2536 and search result respectively.
2538 --- 2.0.1 2003/04/25
2540 Redhat package is now several packages: libyaz (runtime libraries),
2541 libyaz-devel (development and documentation, and yaz (utility programs).
2542 Package spec file by Morten Bogeskov.
2544 New member 'schema' in struct bend_fetch_rr which the name of requested
2545 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2546 handler MAY set this to reflect the schema of the returned record.
2548 New member 'display_term' in struct scan_entry. GFS now sets member entries
2549 and allocates scan entries to be filled by user scan handler. In previous
2550 version, entries member was allocated by the scan handler. That still works,
2551 but the GFS will ignore member display_term - assuming it was NOT set by
2552 the handler. The fact that the GFS now allocates the entries both allows
2553 for new members and makes a scan handler easier to write.
2555 Fix CQL lex buffer overflow.
2557 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2558 SRU default recordPacking is string.
2560 SRU protocol support for frontend server.
2562 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2564 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2566 Added scan for the ZOOM shell (zoomsh).
2570 * String Identifers for Schemas (Amendment 5).
2571 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2572 Old definition for schema
2573 Odr_oid *schema; /* OPT */
2578 Z_InternationalString *uri;
2579 #define Z_Schema_oid 1
2580 #define Z_Schema_uri 2
2583 * resultCount parameter to Sort Response (Amendment 1).
2584 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2586 Support for SRW 1.0 over HTTP. This is an optional feature and
2587 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2590 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2591 on the same port. SRW SearchRetrieveRequests are mapped
2592 to bend_init,bend_search,bend_fetch,bend_close.
2594 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2596 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2597 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2599 ZOOM connections are SRW based if schem http is used for hostname
2600 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2601 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2603 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2604 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2605 distance=n, order=true/false, relation=le, prox unit=word. If
2606 n is omitted, distance 1 is used.
2608 Fixed problem with C compiler include path in wrong order.
2610 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2611 on Solaris. Patch from Ko van der Sloot.
2613 New MARC decode API. All new functions operate on a yaz_marc_t
2614 handle. The most important new functions are: yaz_marc_create,
2615 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2616 decode and destroy respectively. Decoder can produce formats
2617 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2618 include/yaz/marcdisp.h.
2620 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2621 to UTF-8, UCS-32, wchar_t or Latin-1.
2623 * Prototypes for yaz_iconv_-functions moved to separate header
2624 include/yaz/yaz-iconv.h.
2626 Make a few private functions 'static' in unix.c. This prevents
2627 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2629 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2630 are set when Init Response is received.
2632 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2633 but returns diagnostic set as well.
2635 New function yaz_strerror which is a portable wrapper for
2636 strerror/strerror_r/GetLastMessage.
2638 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2639 is returned for MARC. If type is "oai", then OAI MARC is returned.
2641 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2644 --- 1.9.2 2002/11/26
2646 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2648 Fix bad race conditions on SIGTERM and terminate gracefully in
2651 Move retrieval (data1) module to Zebra since nobody seems to be
2654 Add GRS-1 render for ZOOM using same format as yaz-client.
2656 --- 1.9.1 2002/10/05
2658 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2660 Fix broken ESpec handling in data1 module.
2662 SGML reader parses comments and makes them part of the data1 tree.
2664 Added several type casts so that YAZ compiles as C++ code.
2666 ZOOM didn't handle PDU encoding failures properly.
2668 Added more Bib-1 diagnostics (approved extensions).
2670 GNU configure: better check for iconv.
2672 More portable use of accept, getpeername. Check for socklen_t. Use
2673 int/size_t if socklen_t is not defined.
2677 PQF parser rejects bad queries - including those with extra
2678 characters in them. PQF parser used to silently ignore that.
2679 Cleaner API for PQF added, which allows you to get detailed
2680 error information for bad queries (see yaz/pquery.h).
2682 Fixed bug in ZOOM_record_get for type "database".
2684 Implemented mini iconv library supporting conversions between
2685 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2687 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2689 --- 1.8.9 2002/08/20
2691 Fixed ZOOM C record cache so that preferredRecordSyntax and
2692 elementSetName is used to check for already fetched records.
2694 --- 1.8.8 2002/08/02
2696 Added three members in bend_initrequest structure to facilitate
2697 character set negotiation.
2699 Fixed a bug in frontend server that could cause indefinite
2700 loops under rare conditions.
2702 Revised character set utilities (charneg.h) so that encoding
2703 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2705 For PQF, directive @term <type> sets term type for Scan/Search.
2706 Here <type> is general, string, numeric, null. The term type
2707 is inherited - just like @attr.
2709 New call odr_set_charset that sets character set conversion for
2710 international-strings on a ODR stream. Prototype is:
2711 int odr_set_charset(ODR o, const char *to, const char *from);
2712 The InternationalString is still represented as C string in YAZ
2713 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2714 won't). On the protocol level, you can use any encoding.
2716 Support for UNIX sockets in ZOOM.
2718 Solaris recv sometimes returns errno == ENOENT. It is treated as
2719 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2721 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2722 both client and server. Code by Morten Bogeskov.
2724 --- 1.8.7 2002/05/22
2726 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2727 that they can be used directly from Visual Basic. You must recompile
2728 your windows APP if you're using ZOOM.
2730 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2731 Commands "lang" and "charset" sets language and character set respectively.
2732 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2733 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2735 Attributes from multiple CCL fields may be OR'ed rather than merged
2736 using directive "@field or". Fields are still merged by default -
2737 equivalent to "@field merge".
2739 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2742 Fixed bug in zget for parameter ExtendedServicesResponse.
2746 --- 1.8.6 2002/03/25
2748 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2750 Client displays USR.1:SearchResult-1 (hits per term).
2752 Additional Search Info for search in Generic Frontend Server.
2754 Fixed CCL parsing of "field=s".
2756 WIN32 installer - using the excellent NSIS software from nullsoft.
2758 Fixed CCL parsing of "field = - <number>".
2760 Added function yaz_marc_decode that decodes MARC for line mode
2761 display or XML (similar to that used by JZKit).
2763 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2764 Z39.50. But ISO/ILL was, however.
2766 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2767 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2769 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2770 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2772 --- 1.8.5 2002/02/03
2774 New YAZ client features: Command completion and new commands:
2775 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2776 Code provided by Jacob Poulsen.
2778 New call oid_trav, that visits all registered OIDs via callback.
2780 Function ZOOM_record_get now returns const char pointer rather than
2781 void pointer. It saves a lot of type casts.
2783 For YAZ client, command "auth" now allows you to set authentication
2784 in IdPass style. It is enabled when three tokens are given - order
2785 is user, group and password.
2787 Fix memory leaks in MARC record handling for ZOOM.
2789 New option for YAZ client, -k <kilobytes> that sets
2790 maximum record size. Similar to -k option for generic frontend
2791 server and yaz-ztest.
2793 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2795 Prefix query parser reports "fail" when bad attribute set is given.
2797 Fix in MARC decoder. Proximity logging. Fix for attribute set
2798 in scan handler for server. Patches by Shigeru Ishida.
2800 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2803 Configure option --with-openssl=<dir> now works when a directory is
2804 specified. Patch provided by Morten Bogeskov.
2806 New option for YAZ client, -u <auth>, that sets authentication.
2808 ZOOM fix: error information was sometimes "missing", since error
2809 was cleared/reset too when it shouldn't.
2811 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2813 --- 1.8.4 2002/01/04
2815 Scan for ZOOM API. New object ZOOM_scanset. New functions
2816 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2817 ZOOM_scanset_destroy.
2819 New ZOOM function, ZOOM_connection_last_event, that returns type
2820 of last event (such as "receive data", "send data", "apdu received",
2823 New ZOOM option, schema, that specifies schema for retrieval.
2825 New CCL feature. Qualifiers can be aliases for one or more
2826 other qualifiers (if more than one is given, OR is used).
2828 ZOOM uses named result sets if target supports it.
2830 Two new YAZ client commands: . (dot, which sources a script of YAZ
2831 client commands), and ! (to execute shell command.). Implemented
2834 Working on Debian packages.
2836 --- 1.8.3 2001/11/19
2838 YAZ client enables named result sets only if target supports it.
2840 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2842 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2843 with key="host" to get same result.
2845 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2846 Function Z3950_resultset_record(s) returns references to records
2847 "owned" by resultset. To become owner use Z3950_record_clone.
2849 Function z_ext_record handles Extended Services. Thanks to
2852 --- 1.8.2 2001/11/12
2854 CCL Parser fix: ignore token comma when dealing with and-lists.
2856 Documentation updates for COMSTACK.
2858 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2859 Changed prototype Z3950_records. For some functions, int parameters
2860 were changed to size_t.
2862 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2865 New MARC decode/display function, marc_display_exl, which properly rejects
2866 non-ISO2709 records. YAZ client uses it.
2868 --- 1.8.1 2001/10/29
2870 Fix bug: local attribute set wasn't set correctly in PQF strings.
2874 * Old Z39.50 codecs no longer supported.
2876 Added ZOOM C binding. See http://zoom.z3950.org/
2878 Renamed states for COMSTACKs to avoid confusion with events.
2880 Implemented cs_look and proper cs_rcvconnect.
2882 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2884 Configure detects POSIX threads on OpenBSD.
2886 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2887 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2889 When error is returned from present handler, non-surrogate diagnostic
2890 is returned in present response (and fetch handler is no longer called).
2892 * Minor adjustments to pquery parser (PQF). Token characters may be
2893 escaped by using backslash (C-style).
2895 PQF parser allows string attribute values to be specified. For @attr,
2896 non-numeric characters after the equal-sign are treated as strings
2897 (e.g. @attr 9=title).
2899 CCL trunction character may be defined (@truncation in file)
2901 * function zget_ExtendedServicesRequest sets waitAction to
2902 waitIfPossible (was wait).
2904 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2907 CCL operator names may be set in field definition files (CCL_bibset).
2908 See ccl/bib1 for an example.
2910 Fixes in ASN.1 compiler for C++ compatibility.
2912 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2913 and "op_or" to avoid conflict with C++.
2915 Fixed problem with GNU readline detection on Redhat 7.0.
2917 Added step-size for Scan backend handler.
2919 Fixed bug that made the frontend server crash when no attribute
2920 set was specified for scan.
2922 Front-end server automatically switches to original working directory
2923 when installed as an NT service. Previously -w had to be specified to
2926 Added extended attributes for retrieval module (data1), so that data1
2927 records carry d1_readXML/SGML attributes. d1_read also supports
2928 null-data rules ( <tag/>)
2930 On UNIX when POSIX threads are available, a separate library libyazthread
2931 is created. Programmers should link with that library and the yaz library
2932 when using threads. The reason for the split was that some applications
2933 on Linux, such as Apache, doesn't work well when using shared objects that
2936 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2937 (or any frontend server) in SSL mode by specifying ssl: followed by
2938 address. Only tested on UNIX.
2940 Added feature for CCL module. Virtual structure s=al or s=ol generates
2941 and-list and or-list respectively instead of phrase search.
2945 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2946 log_mask_str. This was done to avoid name conflicts with other libraries
2947 (such as other PHP extensions).
2949 Added raw OID member for preferred record syntax (request_format_raw)
2950 and returned record syntax (output_format_raw) for backend fetch method.
2952 Config file yaz-config now accepts options so that it returns specific
2953 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2955 Shared library support for UNIX using GNU libtool.
2957 * Modified backend interface. Request/Response struct's replaced by
2958 one read/write C struct. For example bend_fetchrequest and
2959 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2960 Every handler - even search has to be registered in bend_init
2961 handler. This means that the YAZ library no longer refers to
2962 external functions and it makes it possible to make the whole
2963 thing a single DLL/SO.
2965 Added Segment handler for backend server.
2967 Added Zmbol/Zebra administrative functions to YAZ client.
2969 Threaded frontend server on UNIX (when POSIX Threads are available).
2970 Starting the server with option -T enables multi-threading.
2974 Added configure option --enable-comp/disable-comp to control use
2975 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2976 located in sub directory asn.
2978 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2979 in ${exec_prefix}/bin along with the other programs yaz-client and
2982 GNU automake used to maintain makefiles.
2984 Added several OID's.
2986 Changed retrieval module so that we can load records with no abstract
2987 syntax defined. Tagpaths in these records are fully composed of string
2990 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2994 On UNIX, the generated makefile now supports a proper 'make install'.
2995 The prefix can be set via GNU configure to set the install location
2996 (default is /usr/local).
2998 * YAZ programs client and ztest were renamed to yaz-client and
2999 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3000 locations, such as /usr/bin,/usr/local/bin,etc.
3002 * YAZ Header files were moved from include to include/yaz. YAZ Header
3003 files are referred to as include <yaz/log.h> rather than <log.h>.
3004 The YAZ include path (-I ..) is therefore the same as before. Programmers
3005 should update their #include statements or use -Ipath/include/yaz
3006 instead. The main motivation for doing this change is that YAZ header files
3007 can be installed in "standard" locations /usr/include,/usr/local/include
3008 without introducing conflicts, since ALL YAZ header files are stored
3009 in subdirectory yaz (under /usr/include for example).
3011 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3012 rather than project/workspace files. We switched because project files
3013 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3016 Changed name of logging function, logf, to yaz_log, to prevent name
3017 clash with some math-log functions. The YAZ header log.h defines logf
3018 to yaz_log (#define) so there should be no incompatibilities by this
3021 Added bend_start/bend_stop handlers for server. These handler are
3022 called on start/stop of server. For windows they are called whenever
3023 a service is started/stopped.
3025 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3026 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3027 in util/yc.tcl. The auto-generated C code structures are, in a few
3028 cases, incompatible with the old decoders. There are differences in the
3029 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3030 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3031 The preprocessor variable ASN_COMPILED is defined when the compiled
3032 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3033 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3034 wish to use the old encoders/decoders you can specify --disable-yc
3037 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3038 version so that it supports both new - and old version of DB Update
3040 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3041 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3042 change. The name parameter can be set to 0 in which no name is specified
3043 for the construction. The macros odr_implicit and odr_explicit sets name
3044 parameter to zero for the construction involved. New macros
3045 odr_implicit_tag and odr_explicit_tag are similar to the others,
3046 except that a name parameter is added. For programmers' that don't use
3047 ODR they probably only need to change the call to z_APDU and z_External.
3049 Added access control facility by interfacing the TCP wrapper library.
3050 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3051 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3052 name of the daemon and enables the access control as specified in
3053 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3055 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3056 den Dool <H.M.vdnDool@kub.nl>.
3058 Added reference ID parameter to most functions in server API - refer
3059 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3061 Changed name of ccl library to libccl.a (was ccl.a).
3063 Fixed bug in decoder for Explain (Category TargetInfo).
3065 Added support for GNU readline in client. Thanks to Jacob Poulsen
3066 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3068 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3069 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3070 IMPLEMENTATION! This change was made to the development version before
3071 the ZIG decided to retract the amendment. If any users MUST be
3072 compatible with the original Update definition, PLEASE CONTACT US, and
3073 we will include a separate definition corresponding to the old Update
3074 ES. Note that because of the change to the ASN.1 of the
3075 TaskPackageRecordStructure we cannot define a single structure that
3076 will support both versions.
3078 * Added const modifier to buffer parameter for some ODR/BER encoding
3079 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3080 completeWAIS, odr_dumpBER.
3082 Fixed bug in client.c which caused a crash when a scanResponse didn't
3083 contain positionOfTerm.
3085 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3086 * will cause an error in a client if a non-YAZ target sends both a
3087 * list of Scan entries and non-surrogate diagnostics.
3089 Retrieval module enhancements. Tag sets may be typed in the reference
3090 to it. From the .abs-file the "tagset" directive takes a third optional
3091 integer type for the tag set referenced. From a .tag-file the "include"
3092 directive takes a third optional type as well. The old "type" directive
3093 in the tag set itself is still recognized but acts as the default type
3096 Backend interface change. Individual Scan terms returned from bend_scan
3097 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3098 in include/backend.h.
3100 Retrieval module enhancements. Multiple tag sets and attribute sets may
3101 be specified in abstract syntax specs. Revised the error/warning for
3102 logging messages reported by the retrieval module when reading the
3105 Object Identifier system (oid_..) changed. The API is backwards
3106 compatible but the oid-routines now allocates new OID's when needed.
3107 Raw OID's may be specified in oid_getvalbyname.
3109 YAZ now uses GNU configure to generate Makefile(s).
3111 * Minor changes in some of the member names of DeleteResultSetRequest and
3112 DeleteResultSetResponse. See include/proto.h.
3114 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3115 and added member 'languages' in TargetInfo (which was missing).
3117 Changed the way attribute sets are handled in the retrieval
3118 module. These are now cached, just like the abstract syntaxes
3121 Changed YAZ so that it links with compiled ASN.1.
3123 Added Explain-schema definitions and mapping routines. The following
3124 Explain categories have been implemented: AttributeDetails,
3125 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3127 Fixed minor bug in Windows version of Server Library.
3129 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3131 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3133 Added EXTERNAL: UNIverse Resource Report (non-standard).
3135 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3136 ENUMERATED and SET OF.
3138 * Added 'const' to some of the char pointer arguments for the
3139 functions, data1_read_node, data1_getelementbytagname,
3140 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3143 Fixed bug in data1_insert_taggeddata - the last_child member of
3144 parent wasn't initialised.
3146 * Changed data1_read_record and data1_read_node so that the supplied
3147 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3148 doesn't refer to any parts of the "SGML"-buffer.
3150 Fixed bug in server library (Windows version of statserv_remove).
3152 * Changed code so that it compiles as C++. The type definition
3153 of Odr_fun which is a member of Odr_arm was changed. The result is,
3154 that an explicit typecast is needed for the fun pointer when
3155 using Odr_arm - as in:
3156 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3158 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3160 Implemented the new structured date and time definition as approved
3161 by the ZIG. Added schemaId element to the specificTag in Espec-1
3162 (also approved at the last ZIG). Thanks to RVDM.
3164 Added some Object identifiers (RVDM).
3166 Changed the Update Extended Service (RVDM).
3168 Added command "refid" to client which specifies referenceId for
3169 the following requests.
3171 Implemented extended service handling for server. See ztest.c
3172 for an example as well as backend.h. New handlers are registerd
3173 in the Init handler.
3175 * Changed interface for sort in server.
3177 Added new members to statserv_options_block. It allows a server
3178 to read options from another source than just the command line. Thanks
3179 to Charles Woodfield.
3181 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3182 renamed to zboolean. Some C++ compilers complained about the name.
3184 Minor changes to gils.abs. Added index 's' (sort) on title
3185 and date/time-last-modified.
3187 --- 1.4pl2 1998/1/30
3189 Fixed bug in server library regarding inetd mode (-i). This bug
3190 was introduced by release 1.4.
3192 --- 1.4pl1 1998/1/29
3194 Added sort facility in client and backend server interface.
3196 Fixed problem with dependencies in Makefile(s).
3198 Fixed bugs for encoders/decoders of extended services and
3201 Implemented sub-tree feature for schemas. Sub-trees are
3202 referenced in *.abs-files. See explain.abs for an example
3203 of the use of this feature.
3205 Modified bib1.att; local attributes for ANY didn't include
3206 ANY itself (only affects use of the retrieval module).
3208 Fixed bug in plain SGML reader in function data1_read_node:
3209 tags with prefix "var" was incorrectly interpreted as variants.
3211 Added feature "sub-schemas" to enable references to - and definitions
3212 of - group of elements.
3214 * Removed member parent from type data1_element (in data1.h).
3216 Implemented function odr_nullval() that returns the value of
3219 * Removed member num_children from data1_node (in data1.h).
3221 Made NT service interface part of the server library. The
3222 function statserv_main uses the NT service when required and
3223 calls the statserv_start / statserv_close routines.
3225 Routine zget_SearchRequest and zget_PresentRequest fills
3226 resultSetName/Id member with "default" instead of "Default".
3228 Fixed memory leak in server. Request queue member wasn't freed.
3230 Fixed nmem_exit so that memory is freed.
3234 Revised the CCL parser utility to be thread safe.
3236 Added function, oid_ent_to_oid, to replace the function
3237 oid_getoidbyent, which is not thread safe.
3239 * Added nmem_init and nmem_exit to initialize and release
3240 NMEM resources. Function nmem_init should be called once in the
3241 initial thread before NMEM/ODR is used. statserv.c and client.c
3242 have been changed accordingly. The change was necessary to make
3243 NMEM thread safe. The NMEM memory pool is shared amongst threads
3244 in a process. Unix-based applications will still work fine without
3247 Added NT Services interface for the the Z39.50 (statserv) Server.
3248 Refer to the ztest.c source on the usage.
3250 Windows 95/NT port using MSVC5.0. Project files are included in the
3253 * Defined new 'global' handle for the retrieval (data1) system. The
3254 new handled, data1_handle, describes the state of the data1 system.
3255 This handle is passed as first argument to virtually all
3256 data1 related routines. The functions data1_create and data1_destroy
3257 creates and destroys a data1 handle respectively.
3259 Added ODR encode stream member to all backend request structures
3260 init, search, scan etc. This stream should be used to allocate all
3261 memory used for the response when thread safe operation is needed.
3263 Changed the comstack utility, cs_addstr, to be thread safe. The
3264 returned hostname string returned by the function is now part the
3267 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3268 function. The cs_straddr takes a COMSTACK handle as argument, so this
3269 function must be used after cs_create and before bind/connect.
3270 This function is thread safe.
3272 Moved test server to 'ztest' directory - generic server code still
3273 in 'server' directory.
3275 Made prefix query (pquery.c) utility thread safe.
3277 Added new function modifier YAZ_EXPORT to 'export' public DLL
3278 functions when using windows (see include/yconfig.h).
3280 Added definitions to the OID database (util/oid.c) (RVDM).
3282 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3284 Added call to ccl_rpn_delete in client program.
3286 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3287 release of RPN structure.
3289 Added support for C++, headers uses extern "C" for public definitions.
3290 With input from RVDM.
3292 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3293 Thanks to Ronald van der Meer (RVDM).
3295 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3297 Added support for private extensions to the OID database
3298 (oid_setprivateoids()). Thanks to RVDM.
3300 Added optional, physical ANY (key replication)
3302 Fixed null-reference problem in GRS-1 output filter.
3304 Proximity operator added to Prefix Query Format (PQF).
3306 In test client command "base" accepts multiple databases.
3308 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3312 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3314 Smallish bug-fixes in the new encoders/decoders (explain).
3316 Bug fixed in DeleteRequest.
3318 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3320 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3322 Added SOIF syntax (using private OID for now) to retrieval module and client.
3324 Added Update extended service.
3326 Added SearchResult-1 additional info structure.
3328 Added optional CCL (ISO8777) interpreter as separate module. Available
3331 --- 1.2 1996/6/10 (1st anniversary release)
3333 Added Summary record syntax. Lightly tested.
3335 Added OPAC record syntax. Untested.
3337 Added ResourceReport service encoders/decoders. Untested.
3339 Fixed bug in z_Unit - wrong tagging on unitSystem.
3341 Fixed bug in the DiagRecs decoder.
3343 Added options for max PDU size and session timeout to frontend-server.
3345 Added documentation of query-language parsers and other supporting utilities.
3347 [frontend-server] Added Attribute set to the bend_scanrequest API.
3349 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3350 surrogate diagnostics were generated.
3352 [retrieval] Allow multiple local values for attribute.
3354 [retrieval] Allow multiple attributes per element in .abs files. index type.
3356 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3358 --- 1.1pl2 1996/4/10
3360 Minor changes, mostly specific to Zebra's requirements (retrieval)
3364 Repaired bug in frontend server when running multiple listening
3365 endpoints in dynamic mode.
3367 z_External() now won't break if a known, ASN.1 value comes encapsulated
3368 in an octet-string. The value will pass through unmodified in an Odr_oct.
3370 Added a bit of code to the demo client to decode & display
3371 ASN.1-structured records represented in the octet-aligned branch of
3372 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3374 Added z_ext_getentbyref() to the ASN module. Doc updated.
3376 * Completed the SCAN definition in the ASN module. This may break SCAN
3377 code based on older YAZ-versions at compile-time. The fix is easy -
3380 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3381 under the SCAN definition. Remember to initialize this, server-people.
3383 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3384 that this does not extend to ODR and ASN.
3386 Comstack allows insertion of established socket (primarily for
3387 inetd-operation of servers). Doc updated.
3389 Front-end server can now start from the inetd in TCP mode. Doc
3392 --- 1.0pl4 1996/1/24
3396 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3397 the rank and record number.
3399 Adjustments to the frontend server.
3401 Fixed diagnostic BER dumper. It ignored the file argument.
3405 Various changes to retrieval module.
3407 Changed the union discriminators of the protocol files from enums to
3408 ints paired with #defines.
3410 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3413 *Changed operator in the RPN structure to 'roperator', again to avoid a
3416 Fixed problems in Explain decoders/encoders.
3418 --- 1.0pl2 1995/12/6
3420 Memory bug in log module fixed.
3422 --- 1.0pl1 1995/12/5
3424 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3426 Bug in Explain DatabaseInfo module fixed.
3428 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3432 The shift to v1.0 signals that we now consider the *core* functionality
3433 of YAZ reasonably stable (the core being more or less equivalent to
3434 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3435 tested (Explain not at all - though that will happen soonish).
3437 Minor changes to code to support Windows port.
3439 Various minor changes after we're getting to use GRS-1 & co. more.
3441 Added Espec-1 format.
3443 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3444 of the protocol and it cannot be selected when encoding (maps into 'string'
3445 when decoding). Needed to talk to some servers.
3447 Demo client can request simple element set names.
3449 Added Diagnostic Format encoders/decoders.
3451 Added simple Close handling to frontend server (no hooks for resource
3452 reporting yet), and demonstration client.
3454 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3456 --- 1.0b3 1995/08/24
3458 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3459 handled incorrectly when records were requested in the searchResponse. This
3460 will only affect you if you use the frontend-server.
3462 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3463 Test-client will ask for and print GRS1. Ztest will return dummy records
3466 Added Explain encoders/decoders to the service-level API. Untested.
3468 Added Extended Services: Item Order encoders and decoders to the Service-
3469 level API. Untested. We could use a recent copy of the pertinent bits
3470 of the ILL protocol to add those bits.
3472 Added diagnostic format 1 encoders/decoders to the service-level API.
3475 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3476 odr_cons.c, which causes a more correct output.
3478 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3479 was always set to 0 when no records were requested in the searchRequest.
3481 * Added better external-handling. This shouldn't harm old code that
3482 *encodes* externals. It can break code that looks for a
3483 'single-ASN1-type' representation, since those types that are known
3484 are now decoded immediately. Look at the SUTRS sample code in
3485 seshigh.c and client.c. Documentation updated.
3487 Handling of structured records in bend_fetchresponse. Length -1 marks
3488 structured record, type is deduced from format field.
3490 --- 1.0b2 1995/06/27
3491 Fairly quick maintenance release to add SUTRS support.
3493 Fixed handling of SUTRS records in the demonstration client.
3495 * Added format field to the bend_fetchrequest and bend_fetchresponce
3496 structures of the backend API (frontend server). When the record is
3497 returned, the value of the format field is mapped to an OID. The
3498 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3499 of the record. The special value VAL_NONE in the bend_request means
3500 that no specific format was requested by the client. Documentation
3501 updated accordingly. Test server (ztest) will return a fixed dummy
3502 SUTRS record if your client requests SUTRS.
3504 Documentation updated accordingly.
3506 You can now set external libraries and RANLIB support in the top-level
3510 First public release.
