3 solr-pz2.xsl: extend Solr transformation to emit license_name field PAZ-996
5 cf.xsl: forwards flat affiliation structure PAZ-992
7 parpar2: log YAZ version upon start PAZ-993
9 Update and fix documentation for preferred targets
11 Fix spelling of present_chunk in documentation
15 Increase facet limit PAZ-990
16 No longer a limit on facets.
18 Pazpar2-js no longer requires Apache2 PAZ-989
19 Package pazpar2-apache2 sets up everything WRT apache and only
20 package which requires it. pazpar2-apache depends on pazpar2-js.
24 Larger string buffer for forward address PAZ-987
25 Fixes buffer overflow that could occur if forward address is IPV6.
27 Updates to Windows NMAKE makefile for Visual Studio 2013.
31 Use YAZ backtrace facility PAZ-983. In case of crashes YAZ log may
32 include more details about the fault. Better install gdb and the
33 debug version of pazpar2 (pazpar2-dbg on Debian/Ubuntu).
35 Per target timeout PAZ-981
36 New setting pz:timeout which overrides z3950_operation timeout
41 Re-introduce journal-subpart PAZ-980
42 Both citation and journal-subpart have same value.
46 Add Ubuntu utopic 14.04 and Ubuntu saucy 13.10 to the list of packages
49 Remove from js/pz2.js the code that translates just two diagnostic
50 codes (1 and 2) into human-readable messages. This is no longer
51 necessary at all, as PazPar2 has been returning the message as well as
52 the code in its responses since December 2012. Fixes PAZ-978.
54 primo xsl produces citation rather than journal-subpart PAZ-972
55 (fix in 1.8.1 was incorrect)
57 Fix missing .url files PAZ-977
58 Add missing .url+.cfg and add proper check for it.
62 Turbomarc needs number check for date 903 map PAZ-973
64 primo-pz2.xsl creates citation rather than journal-subpart PAZ-972
66 pz2.js: on successful search, issue a "show" command only if a show
67 callback function has been installed. Fixes part of PAZ-975
71 New command=stop which stops further search&retrieval for active
74 CF/primo XSL generates {volume,issue,pages}-number that are defined
75 in default Pazpar2 service definition. PAZ-968 PAZ-970
79 Various fixes for threaded operation PAZ-960 thru PAZ-966
81 Dump main configuration file during start of Pazpar2 PAZ-957
85 Log ingest failures and record failures:
87 Clean up logging PAZ-942
88 Use session lead in more places. Log hits/records/filtered for each
89 target when fetching is complete. Log hit count when a search
90 (response) is received. Remove some less useful log messages.
92 Fix warning about about missing (internal) stylesheet PAZ-956
94 Report number of filtered records in bytarget PAZ-954
96 Cache XML documents as they appear after normalization. The key
97 for the cache is database+record offset. Cache is removed if query
98 is modified for search. This speeds up re-establishing a result set
99 for databases where new query is same previous query.
103 poll: add assert for number of FDs; abort on poll failure
107 Fix hang for 2nd use of target with unresolved DNS PAZ-949
111 Use poll rather than select for main event loop to overcome limit of
112 1024 file descriptors PAZ-947
114 Override setting with same name (do not append) PAZ-945
118 Separate package: pazpar2-xsl PAZ-932
120 --- 1.6.44 2014/06/27
122 Update OPAC stylesheets for availabilityDate PAZ-943
124 Fix too funny startrecs description
126 Fix broken ~ match if filter contains = PAZ-941
128 --- 1.6.43 2014/06/12
130 Add pz:redis option for ZOOM caching using redis. This is an alternative
131 to memcached. Requires YAZ 5.2.0 to work.
133 --- 1.6.42 2014/05/06
135 Re-ingest native facets PAZ-934
137 Fix medium override for solr-pz2.xsl.
139 --- 1.6.41 2014/04/23
141 Fix URL with leading http:// not working PAZ-933
143 Build packages for Ubuntu Trusty Tahr 14.04 LTS
145 cf.xsl: handle medium override AND md field
147 --- 1.6.40 2014/04/10
149 sortmap relevance always uses increasing=1. PAZ-930
151 solr-pz2.xsl: ensure medium is also applied if Solr record do not
154 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
155 this code is only executed once.
157 Fix typos is sortmap documentation.
159 Doc: fix misplaced variablelist tag.
161 --- 1.6.39 2014/02/19
163 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
164 It's been like that since version 1.1.1 from August 2009.
166 Add support for result-set caching via memcached. See description of
167 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
169 Add support for a <metadata> container tag. Patfh from Sven Porst.
171 Add support for XInclude in main configuarion file. Patch from Sven Porst.
173 Add client_{lock,unlock} before call to non_block_events in
174 connection_continue. Problem is that if non_block_events fire records,
175 then we will not unlock client at all. And as a result, a dead-lock
178 --- 1.6.38 2014/01/07
180 Avoid removing slash and other characters for generic metadata that
181 looks like a URL (contains ://). PAZ-915
183 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
185 Cluster merge fixes. PAZ-901
187 Set client state to "working" when waiting for DNS resolver. PAZ-907
189 Log when session terminates. PAZ-905
191 Fix LSB/HS conformance for /etc/init.d/pazpar2 PAZ-904
192 Debian: add support for /etc/init.d/pazpar2 status
194 --- 1.6.37 2013/11/18
196 Fix 'Record Missing' for command=show PAZ-903
198 Preserve order of records within cluster PAZ-902
200 testing: use yaz-ztest -V if possible and use YAZ in sibling directory
203 Allow clustered records to be ingested during retrieval. PAZ-900
205 Fix void function error which cannot return a value.
207 --- 1.6.36 2013/11/11
209 SRU pz:authentication="a/b" may end up as x-username=a%2Fb PAZ-899
211 Upgrade to debhelper version 7 PAZ-898
213 Package with libyaz5 PAZ-897
215 Better error message for CCL parse errors PAZ-887
217 --- 1.6.35 2013/09/23
219 New target setting: pz:authentication_mode. PAZ-896
221 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
223 Strip #-suffix for ZOOM URLs. PAZ-892
225 --- 1.6.34 2013/08/30
227 Fix issue with hanging show/bytarget. Could happen if new search was
228 fired with filter before show from previous show completed.
230 Add 'date' handling for solr-pz2.xsl.
232 --- 1.6.33 2013/08/13
234 pz:authentication may carry user group password. If pz:authentication
235 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
236 authentication. Two forms are allowed
239 If no blanks are present, open authentication is in use (as before).
241 Fix {prev,next}recid elements that are returned by record
242 command. These were incorrect in versions 1.6.23 thru 1.6.32.
244 --- 1.6.32 2013/06/14
246 Experimental support for snippets. If argument snippets=1 is given
247 for command record or show, the text will include <match>-tags for
248 those area that matches.
250 Fix memory leak WRT client structures (incorrect inc ref count).
252 Log when a HTTP response is serialized and the time elapsed.
254 New command, service, which returns current service XML in use for
257 --- 1.6.31 2013/05/24
259 Local limit for fields of type "generic" (ie text fields) are
260 now normalized by mergekey rule before comparison takes place.
261 Before, no normalization took place and comparsion was, thus, exact.
263 New facility: dynamic rank , which allows ranking to be changed
264 for an existing result set. The rank can be set for search or
265 show. This overrides the rank for metadata elements (which fields
268 New facility:dynamic mergekey , which allows mergekey to be changed
269 for an existing result set. The mergekey can be set for search or
272 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
273 Also, allow ports to be given as names (not just integers).
274 Fix @-notation on systems that don't support IPV6 sockets.
276 --- 1.6.30 2013/04/26
278 Add MasterKey Connect configuration. Refer to section "non-standard
279 databases" for more information.
281 Allow timeformat for log to be specified with option -m (as Metaproxy
284 New Debian package pazpar2-dbg.
286 Fix NULL ptr reference of se->relevance. If a new search is initiated
287 and a CCL query fails to parse, Pazpar2 could crash.
289 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
290 existed in 1.6.29 only.
292 --- 1.6.29 2013/04/05
294 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
295 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
296 changed by setting "host" attribute for the "listen" element.
298 Change semantics of pz:extendrecs. Allow for repeated fetches .
299 pz:extendrecs is now the number of extra records to fetch (was total
302 --- 1.6.28 2013/03/21
304 Fix hang or memory violation if show occurred before a search. (not that
305 it makes much sense to perform a show before a search).
307 --- 1.6.27 2013/03/08
309 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
312 --- 1.6.26 2013/03/08
314 New pz:metadata attribute, empty="empty-value" for Pazpar2's
315 internal representation. With this attribute, Pazpar2 treates an empty
316 pz:metadata type as having the value for "empty" - if empty.
318 New setting, pz:extendrecs, which triggers extended fetch of records
319 for a database beyond pz:maxrecs for a show command.
321 Fix warning that was falsely issued for "missing limitmap".
323 Log message for Pazpart start/stop changed. Now using same style as
324 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
326 --- 1.6.25 2013/02/07
328 Fix hang of 2nd command=show with esn/syntax given.
330 --- 1.6.24 2013/01/18
332 New merge attribute type: 'first', which takes all metadata fields
333 from first target that returns the particular field.
335 --- 1.6.23 2013/01/02
337 Extend info command with hostname and YAZ SHA1
338 Indent results for both command stat and info.
340 Allow limit on merged content. The new configuration metadata
341 element, limitcluster, configures that a metadata element (name) be used
342 as limit name for search. Applies to the whole service (ie all targets),
343 unlike pz:limitmap which is configured per-target (database).
345 New feature: limitmap local:* matches against all metadata fields.
347 Allow repeated list in limitmap spec . Separated by comma. For
348 example: value="local:title,rpn:@attr 1=4".
350 New element <message> in bytarget response. Holds diagnostic message
351 of code (say 'Unsupported Use Attribute' for Bib-1 114).
353 Improved logging for record ingestion failures.
355 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
356 when YAZ is compiled without ICU support.
358 --- 1.6.22 2012/10/11
360 Requires YAZ-4.2.40 to support native solr support.
362 Fix and improve logic handling whether or not to re-do search on sort
363 order changes. A sort order with change in ascending/descending only
364 whould not trigger a new search, which is required for targets with
365 native sorting capabilities. Each client is now checked if instructions
366 (sortmap) exist for native sorting and only client that does requires
367 it is researched. Other clients is just re-ingesting the records,
368 they already have. The resultset is now cleared if any researching
371 Connection sharing between session has broken since version 1.6.8 with
372 introduction of logic that would minimize searching if pazpar2 could
373 detect this based on same query and limits and partly sort order.
374 This could lead to segementations violations.
376 Added a chapter in the manaul about relevance ranking.
378 --- 1.6.21 2012/09/24
380 Rank tweak: follow=number will increase mult by number if two terms
381 occur next to each other; number-1 if they are one term apart , .. 0
382 if they are number a part (all in order). Default is 0 (following
383 terms has no effect).
385 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
386 value given by lead and l is length from beginning of field where
387 term occurs (l=0 for first term, l=1 for second term, ..). Default
390 Rank tweak: length=strategy. length="linear" if mult is to be divided
391 by length (existing, default behavior), length="log" if mult is to be
392 divided by log2(1+length), length="none" if mult is not to be affected
395 --- 1.6.20 2012/09/21
397 Rank algorithm details may be printed as part of show response in
398 element <relevance_info>.. This is only printed if <rank debug="yes"/>
401 Record as returned by show/record command have a minimal indentation
402 which makes things human-readable.
404 New configuration of default sorting criteria (sort-default) in
405 service definition. If no criteria is defined it will be as before
408 Search command now supports sort parameter just as the show command.
409 If no parameter is give, it will use the service sort-default value.
411 --- 1.6.19 2012/09/18
413 Rank algorithm skips strings that gets normalized to empty string.
414 For example, & and ! could map to the empty string. The weight for
415 those terms is now 0 (as if they were not part of the query).
417 Rank algorithm does not use CCL from limitmap; only from the query
418 parameter (user query).
422 --- 1.6.18 2012/09/17
424 Rank algorithm configurable by 'rank' element inside service. So far
425 only, attribute 'cluster' is recognized. If cluster="yes", multiple
426 records inside a cluster boosts higher than single records. This
427 is default behavior and existing behavior. cluster="no" takes the
428 average score of each record in a cluster.
430 --- 1.6.17 2012/09/05
432 Fix bad re-use of connections (connections with changing proxy should not
435 --- 1.6.16 2012/08/22
437 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
438 resultset and sorting when the sort order is position. However this will be done on
439 every client poll, which will make pazpar2 continuing reset and fetching.
440 It should only be done on FIRST request where the sort order change.
442 Fix an issue on suggestion option: Also disable suggestions on empty string.
444 Clean up in turbo marc stylesheet.
446 Remove the hardcoded size of termlists.
448 --- 1.6.15 2012/06/27
450 New facility: ccldirective may be given in service definition. Allows
451 CCL parsing to be customized a bit, such as defining names of operators
454 New facility: raw record by checksum, rather than offset. The record
455 command optionally takes checksum which identifies certain record from
458 New facility: per field ranking. Rank may be given as M [F N] where
459 M is default rank and N is rank for CCL terms from field F.
461 --- 1.6.14 2012/06/04
463 Fix for IE7/8 in pz.js
465 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
467 Lower log level some places.
469 Remove some invalid test results.
471 --- 1.6.13 2012/05/23
473 Introducing a version=2 parameter for show, termlist and bytarget commands.
474 This enables pazpar2 to return approximation on hit and count count when
475 doing record filtering using the limit parameter on search and a
476 limitmap with a value of "local:"
478 Setting pz:xslt may embed local XSLT as an alternative to referring
480 Value is not CDATA but XML nodes embedded, so escaping is not necessary
481 but a root element *must* be present. For example:
482 <settings target="target="z3950.indexdata.com/marc">
491 Metadata field rank may given by XML internal document (pz:xslt
492 result). If rank is not given, the rank from service description is
495 Metadata field can now configured a default limitmap and facetmap.
496 Setting limitmap to "local:" would work for all kind of targets, but would
497 prob. not be the optimal solution. But at least better than the default behavior
498 of pazpar2 where no filtering is done.
500 A service definition can now also contains <set/> that defines service-wide
501 settings. These will override server-wide sets and will be overridded by
504 New setting, pz:present_chunk, that specifies number of records to fetch
505 at a time. Zero will disable chunkation; will fetch max_records at once.
507 --- 1.6.12 2012/03/14
509 Revert the format change in termlist response, that could break
510 some clients / UIs since they were expecting an (empty) element
511 if no facet values was found.
513 --- 1.6.11 2012/03/07
515 Revert the behavior of returning errors when unable to block
516 on termlist, bytarget and search, when unable to block due to
517 other block. The client will now receive a regular response,
518 but it will be logged in the server. A parameter (report) is
519 added to change behavior to return error response or WARNING
520 status message. Consider this "API" as private, as it is mostly
521 untested and could be changed in future releases.
523 Fix spell error in pz2.js fix in 1.6.10.
525 New Marc2TurboMarc.xsl (contribution from Sven Porst).
526 Can solve the missing marc21.xsl updates in some cases.
528 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
529 substring (contribtion from Sven Porst)
531 marc21.xsl: fix 1-based substring call
533 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
535 Add test_termlist_block to test suite
537 --- 1.6.10 2012/02/23
539 Fix SEGV for invalid PQFs and SRU/SOLR targets
540 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
542 Fix pz2.js: "null object" due to change in in bytarget result XML.
544 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
545 Added this normalization to the other subject-long fields (d6xx),
546 where it was missing.
548 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
549 Still differences around medium and holdings. marc21.xsl is not
550 longer active used by Index Data, and should be considered unsupported.
551 Use tmarc.xsl instead.
555 Fix SEGV that could occur for failed connections.
559 Fix bug for command sort that could return no results for active clients
560 (from previous search). This bug was present in 1.6.6-1.6.7.
562 Fix bug in results that could include results that should have been
563 filtered out. This bug was present in 1.6.6-1.6.7.
567 Fix bug introduced in 1.6.6 where a connection re-use could stall
570 Local filtering may now specify a local metadata field, eg.
571 pz:limitmap:somefield[t]=local:otherfield
575 For search, when limit and or filtering is in place and search
576 is identical to previous search, the result set is re-used and the
577 target is not searched.
579 Limits may work perform local filtering as well, by using "local:"
584 Updated bytarget command to contain a suggestions element with misspelled
585 words and suggestions to these. pz2.js has been updated to deliver this
586 onwards as well. Only target that currently delivers this is the solr
587 client in YAZ 4.2.18.
591 New service definition element, xslt, that allows an embedded stylesheet
592 to be defined. This can be referred to from pz:xslt as an alternative to
595 New pz:sortmap:field setting for specifying hints on how to make
596 a target natively sort on a field. This is used for command=show in
597 conjunction with sort.
599 New pz:url setting for specifying the actual URL for a target. When
600 this is used the target ID is not used as URL anymore and the target ID
601 may be almost any string (not including []).
603 command=termlist without name parameter returns all termlists/facets.
604 Previously if name parameter was omitted, only "subject" was returned.
608 Make termlist sorting stable. Terms with same frequency are now sorted by
609 their display name. This makes a pretty display and improves our
610 regression test because qsort is not a stable sort.
612 New sort parameter value 'position'. The 'position' sorts merged records
613 by their original position from the remote target. This is primarily useful
614 for debugging and may be used for targets that already perform some kind
615 of relevance ranking. Note that sort by default is decreasing; so to get
616 records in their original order sort=position:1 must be used.
620 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
622 Facility to change working directory for pazpar2 daemon. Option -wdir
623 sets working directory to dir. This facility is useful if core dumps
624 must be saved. In this case, the current working directory must be
625 writable by the running user, such as "nobody".
629 New configuration element <icu_chain> for <server>/<service> which
630 allows a named ICU rule (chain) to be defined. The names relevance,
631 sort, mergekey and facet are used for those operations. The definition
632 <icu_chain id="sort" locale="en"> .. </icu_chain>
634 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
635 And so on.. for relevance, mergekey and facet as well. The latter
636 style is deprecated. The facet terms are normalized by the facet
637 rule by default. This may be changed on a metadata field basis by
638 defining the new attribute 'facetrule' for the metadata element.
640 <icu_chain id="myrule" locale="en"> ... </icu_chain>
641 <metadata name="author" termlist="yes" facetrule="myrule"/>
643 Preserve rorder for merged metadata. Fixes issue as reported by Sven
644 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
646 tmarc.xsl: set journal-subpart to 773$ only.
650 Modify the behavior for the limit parameter (first defined in 1.5.7).
651 Mapping of limit searches are now defined by the new configuration item
652 pz:limitmap. Fix a dead-lock problem with the limit parameter.
654 Extend tmarc.xsl to extract 773$g data (OpenURL).
658 ICU default maps remove backquote (`).
660 Command 'search' takes limit parameter (optional). The limit parameter
661 allows a search to be limited one or more facets and the corresponding
662 values. This is for server side filtering.
664 Configure tweak: Use -lm for log(3) if needed
668 Fix a problem with skiparticle sortkey that could be completely
669 ignored (and reduced to "").
671 Fix dependency problem in pazpar2 RPM package (did not require
672 libyaz4 as it should).
676 Fix memory leak that occurred for command=termlist&name=xtargets .
678 Pazpar2 may save HTTP requests. Enabled by option -R.
682 Experimental support for DTIC DADS target. New dads-pz2.xsl.
684 Support for query_syntax (overrides the default for SRU | Z39.50)
686 Support for extraArgs (ZOOM "extraArgs" option) for targets
688 New commands: status-server and status-session
692 Fix for threaded runs: Client now have a copy of the database URL,
693 which can used after the database has been release from the client.
694 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
696 tmarc.xsl: Add journal-title-abbrev and full text.
698 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
700 Fix for cmd=record before search.
702 Session Logging clean up.
704 Fix wrong termlist factor when maxrecs is different from 100.
708 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
709 Term factor is default enabled but can be diseabled by
710 pz:termlist_term_factor=0
714 Add scaling of facet count. Currently always enabled, needs fixing.
715 Allow user-defined info for target suffix. This has no meaning in
716 Pazpar2 except to distinguish targets from each other. The suffix
717 data begins with #. For example z3950.indexdata.com/gils#Mydata
719 Added exact-match recordfilter; format name=value
723 SOLR support. Pazpar2 may operate as web service client for SOLR.
727 Fix for show command and block=1 (dead lock). Bug was introduced in
732 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
733 tested on CentOS 5.5 only.
737 Fix problem with result sets being removed from a client session
738 if the connection for it was resused by another session. Bug #3489.
740 New iphone UI for Pazpar2 (www/iphone).
744 Fixes for threaded operation.
746 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
748 New example services in etc/services in source. In the Debian packages
749 these are located in /etc/pazpar2/services-available
751 Threaded mode operational on Windows. Requires Windows 7 or Windows
754 Default value of setting pz:max_connections is 0 which means that there
755 is no limit on number of connections.
759 Pazpar2 may operate in threaded mode. Enabled by element threads in
760 the configuration. See pazpar2_conf for details.
762 New setting setting: pz:max_connections. Setting pz:max_connections is
763 a limit of number of sockets to a host. When this limit is reached,
764 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
765 The client will be marked Client_Error when it can not be searched
766 (other clients in a session may work). If pz:max_connections is not set
767 for a target, a value of 30 will be used. Note: the pz:max_connections
768 will only work in threaded mode.
770 pz2.js: JSON support for show.
772 Debian package: Enable default service, default.xml, before starting
773 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
777 Debian version depends on on libyaz4. Note that Pazpar2 will still
778 compile from source with YAZ 3.
780 Split services into separate files. The example configuration file
781 pazpar2.cfg.dist now includes a default service default.xml (part of
782 etc). And default.xml includes settings/edu.xml. The default.xml file,
783 not to be confused with settings/defaults.xml, is a template for jsdemo
784 and other services. The Debian package installs /etc/pazpar2/server.xml
785 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
786 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
787 The default.xml (from etc) is installed in /etc/pazpar2/services-available
788 and a symlink to it is created from services-enabled. The default.xml
789 service is unnamed and, thus, will be used by jsdemo and test1.
791 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
792 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
796 Support for additional fields in cf.xsl and pazpar2.conf.dist:
797 publisher, available, due, location (=locallocation), callno
798 (=callnumber), thumburl and score.
800 Describe pz:xslt and the auto setting.
802 Move mergekey definition away from the normalization stylesheets and
803 define a mergekey common for all target types in pazpar2.cfg.
805 Code update: Use the Odr_int type for hit counts. This is part of
806 YAZ 3.0.47 and later and so configure checks for that.
810 Metadata attribute 'skiparticle' also works for ICU based
811 normalization. (was only working for the non-ICU/ASCII before).
813 Command bytarget with argument settings=1 will show settings per
814 target.. This is to be able to verify correct settings and be able to
815 test that they are correct. The database settings array size is now
816 also stored.. Problems with database settings array is that if not
817 careful it will be too small (smaller than dictionary per-service
820 Make record list sorting stable by comparing mergekey for records if
821 relevance/title or other sorting criteria all match. This is merely to
822 ensure that our regressions tests works (reproducible output).
824 Relevance calculation changes: use a different denominator (length) for
825 per-field relevance scoring.. Instead of length of all ranked fields we
826 now use length of individual fields (as if they were individual "free"
827 text fields). This will ensure that documents with a long field with no
828 match (say description) will not "hurt" a title match.
830 Diagnostic member was not set on connection error. Fixed
834 Command search takes two optional parameters, startecs and maxrecs,
835 that specifies the start offset (0, 1, ...) and maximum number of records
836 to fetch for each target.
838 XSLTs + MARC maps are cached within a session so we don't re-parse
839 them over and over again. Even for a session with a single search
840 there's much to be gained because many targets use the same
843 The metadata attribute 'mergekey' now takes one of three values 'no',
844 'required', 'optional' . And the resulting mergekey from metadata
845 is now ordered in the same way as metadata in the service definition.
846 Older Pazpar2 version use the order in which metadata appeared in a
849 The search argument 'filter' now offers a new operator ~ which does a
850 substring match. The = operator works as before: string match for
851 anything but pz:id, or target match for pz:id.
853 New setting pz:recordfilter. The value of this setting takes the
854 form name[~value]. This setting makes Pazpar2 ignore all retrieved
855 records that do not have the metadata element name with value substring
858 Pazpar2 allows YAZ log level to be set (option -v).
862 For WS responses Pazpar2 creates XML header. Exception: raw record.
864 Setting XML files are now stored in etc/settings instead of etc. This
865 reflects the layout with the Debian package layout.
867 Settings may be posted for command=settings. The POSTed settings must
868 have root element 'settings' like regular setting files. In order to be
869 recognized, the POST request must use Content-Type=text/xml.
871 A service may be posted for command=init. This service will be used
872 during the session. The service may have its own target settings,
873 ICU config, timeout, etc. In order to be recognized, the POST request
874 must use Content-Type=text/xml.
876 Timeout values may be given per-service. That's element 'timeout'
877 which takes three attribute values (a subset may be given): 'session',
878 'z3950_operation', 'z3950_session'. Option -T is no longer supported
879 - used to specify session timeout.
881 Option -t tests the Pazpar2 configuration and returns exit code
882 (0=success, non-zero=failure). In previous version of Pazpar2, -t
883 specified local settings.
885 In version 1.2.0 the configuration file - after include processing -
886 was dumped to stdout. Now, the configuration is only dumped to the
887 yaz log file if option -d is given.
891 Configuration may now have multiple server areas. This means that a
892 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
893 yet supported - on a server basis. Configuration may also have multiple
894 services .. That is repeating service elements inside a server. Each
895 has an attribute 'id' which serves as service ID. This ID in turn may
896 be used in a Pazpar2 session, by specifying parameter service=ID for
897 command init. There can be at most one unnamed service inside a server
898 which can be referred to by not specifying an service ID for command
899 init (backwards compatible). In order to partition multiple servers and
900 services a new include directive has been added. This takes an attribute
901 'src' which specifies one or more sub-files. For example to include
902 service files, one might use:
903 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
904 It is the intention that that completely makes the settings directive
907 Fix problem where the record command would wait forever if there were
908 no targets to wait for (activeclients == 0).
912 One result set is created per session (last search) rather than for
913 each connection which happen to be shared (bug #3009).
915 marc21 stylesheets changed for efficiency.
919 Session timeout may be specified on the command-line as option -T.
921 Pazpar2 may now be operated in a no-merged mode for records.. All records
922 will be considered unique. This mode is enabled if no mergekey is
923 generated by the normalization stylesheet (pz:xslt).
925 Pazpar2 caches original records from each target and the 'record' command
926 with offset returns the original record if 'syntax' and 'esn' are NOT
927 specified. This speeds up retrieval of original records but also means
928 that Pazpar2 uses more memory. The cached records will be freed when the
929 session terminates or a new search is executed.
931 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
932 library part of YAZ is used.
934 Added SRU client support.
936 Automatically computes pz:nativesyntax if not provided. Works for XML and
939 --- 1.0.13 2008/11/24

955 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
959 Changed the JS library pz2.js to use POST for long URL (+ params).
961 Added installation instructions for Windows. Note: NT services is
962 NOT available until we make a new release of YAZ.
964 Preserve order of repeated metadata fields (they were reversed before).
966 More MARC21 information extracted for metadata.
970 Fixed bug #1162: HTML entities are not escaped properly.
972 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
976 Marc21 stylesheet updated to reflect multiple full text fields
980 Fixed bug in pz2.js WRT DOMElement attributes on IE.
982 Fixed bug 2100: Database wildcards not working
986 Added support for retrieval of records in binary.
988 Fixed bug 1794: Pazpar2 does not return valid XML.
990 Deal with ICU not returning sortkey (resulted in SEGV before).
994 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
995 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
997 Improved diagnostics when Pazpar2 HTTP decoding fails.
999 Pazpar2 requests may be POSTed as using Content-Type
1000 application/x-www-form-urlencoded.
1002 Pazpar2 honors LF in HTTP headers.
1004 Handle targets that handle negative hit counts (should not happen, but it
1007 --- 1.0.3 2007/09/19
1009 ICU is used for tokenization and normalization of the following: mergekey,
1010 sorting, relevance terms.
1012 Debian package now enables ICU tokenization and normalization by default.
1014 --- 1.0.2 2007/08/22
1016 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1017 ways: Either as parameters to the normalization stylesheets (which would allow the
1018 programmer to postprocess or use the values in any way) or after the normalization
1019 step, in which case values are made part of the normalized record (and available for
1020 sorting, termlists, display, or other interface-related use.
1022 Implemented sorting by year.
1024 Option -d dumps records to the current log file instead of stderr.
1026 Fixes for compilation on cygwin.
1028 Z39.50 client code uses pz:elements. pz:elements was recognized in
1029 earlier Pazpar2 versions but it was not used for anything.
1031 icu_chain_test is using fgets instead of getline - fixes compilation
1034 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1035 query conversions fail (rather than _any_). This means targets that do
1036 not support some fields are ignored in a search.
1038 --- 1.0.1 2007/07/03
1040 Improved handling of socket timeout for Z39.50 connections.
1042 Misc documentation updates and spell fixes.
1044 Debian package pazpar2 creates log rotate entry.
1046 Debian package pazpar2-apache2 reloads Apache2.
1048 jsdemo included in distribution. It illustrates the use of the js/pz2.js
