5 Fix leak in record parsing
6 Occurred when empty data was produced and metadata did not have the
7 attribute "empty". The empty attribute was introduced in PAZ-858
9 Updates to pz:authentication documentation
11 Refer to full Apache product
13 Document info command. This command has been around since first release
14 in 2007. Command info includes versions, statistics, etc.
15 The undocumented server-status comand is gone and completely replaced by
16 command info which returns general information of the pazpar2 instance.

34 Log levels http+iochan for tests. Wait longer time in valgrind mode.
38 Facility disable/logging of POSTed content PAZ-1027
39 Log level "post" controls whether POSTed content is logged. This
40 is enabled by default. To disable, use -v -post on the command line.

52 Fix PAZPAR2_PPMUTEX_H incorrectly defined PAZ-1023
54 Fix windows: crash in xmlDocFormatDump PAZ-1021
55 Problem is the passed FILE*. We can not pass FILE pointers between
56 DLLs. So we just avoid dumping the XML config during start on Windows.
58 Use YAZ comstack features for IPv6 and non-blocking getaddrinfo. PAZ-927

108 Limitmap ccl: deal with quotes and backslash PAZ-999
110 Handle date range from a limit parameter PAZ-997
111 The CCL term is not quoted unless it includes blanks. This will ensure
112 that r=r is handled correctly. This changes behavior a bit. If term
113 should not be converted to @and, then instead of r=r one should use

132 Increase facet limit PAZ-990
133 No longer a limit on facets.
135 Pazpar2-js no longer requires Apache2 PAZ-989
136 Package pazpar2-apache2 sets up everything WRT apache and only
137 package which requires it. pazpar2-apache depends on pazpar2-js.
141 Larger string buffer for forward address PAZ-987
142 Fixes buffer overflow that could occur if forward address is IPV6.
144 Updates to Windows NMAKE makefile for Visual Studio 2013.
148 Use YAZ backtrace facility PAZ-983. In case of crashes YAZ log may
149 include more details about the fault. Better install gdb and the
150 debug version of pazpar2 (pazpar2-dbg on Debian/Ubuntu).
152 Per target timeout PAZ-981
153 New setting pz:timeout which overrides z3950_operation timeout
158 Re-introduce journal-subpart PAZ-980
159 Both citation and journal-subpart have same value.
163 Add Ubuntu utopic 14.04 and Ubuntu saucy 13.10 to the list of packages
166 Remove from js/pz2.js the code that translates just two diagnostic
167 codes (1 and 2) into human-readable messages. This is no longer
168 necessary at all, as PazPar2 has been returning the message as well as
169 the code in its responses since December 2012. Fixes PAZ-978.
171 primo xsl produces citation rather than journal-subpart PAZ-972
172 (fix in 1.8.1 was incorrect)
174 Fix missing .url files PAZ-977
175 Add missing .url+.cfg and add proper check for it.
179 Turbomarc needs number check for date 903 map PAZ-973
181 primo-pz2.xsl creates citation rather than journal-subpart PAZ-972
183 pz2.js: on successful search, issue a "show" command only if a show
184 callback function has been installed. Fixes part of PAZ-975
188 New command=stop which stops further search&retrieval for active
191 CF/primo XSL generates {volume,issue,pages}-number that are defined
192 in default Pazpar2 service definition. PAZ-968 PAZ-970
196 Various fixes for threaded operation PAZ-960 thru PAZ-966
198 Dump main configuration file during start of Pazpar2 PAZ-957
202 Log ingest failures and record failures:
204 Clean up logging PAZ-942
205 Use session lead in more places. Log hits/records/filtered for each
206 target when fetching is complete. Log hit count when a search
207 (response) is received. Remove some less useful log messages.
209 Fix warning about about missing (internal) stylesheet PAZ-956
211 Report number of filtered records in bytarget PAZ-954
213 Cache XML documents as they appear after normalization. The key
214 for the cache is database+record offset. Cache is removed if query
215 is modified for search. This speeds up re-establishing a result set
216 for databases where new query is same previous query.
220 poll: add assert for number of FDs; abort on poll failure
224 Fix hang for 2nd use of target with unresolved DNS PAZ-949

266 sortmap relevance always uses increasing=1. PAZ-930
268 solr-pz2.xsl: ensure medium is also applied if Solr record do not
271 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
272 this code is only executed once.
274 Fix typos is sortmap documentation.
276 Doc: fix misplaced variablelist tag.
278 --- 1.6.39 2014/02/19
280 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
281 It's been like that since version 1.1.1 from August 2009.
283 Add support for result-set caching via memcached. See description of
284 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
286 Add support for a <metadata> container tag. Patfh from Sven Porst.
288 Add support for XInclude in main configuarion file. Patch from Sven Porst.
290 Add client_{lock,unlock} before call to non_block_events in
291 connection_continue. Problem is that if non_block_events fire records,
292 then we will not unlock client at all. And as a result, a dead-lock
295 --- 1.6.38 2014/01/07
297 Avoid removing slash and other characters for generic metadata that
298 looks like a URL (contains ://). PAZ-915
300 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
302 Cluster merge fixes. PAZ-901
304 Set client state to "working" when waiting for DNS resolver. PAZ-907
306 Log when session terminates. PAZ-905

336 New target setting: pz:authentication_mode. PAZ-896
338 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
340 Strip #-suffix for ZOOM URLs. PAZ-892
342 --- 1.6.34 2013/08/30
344 Fix issue with hanging show/bytarget. Could happen if new search was
345 fired with filter before show from previous show completed.
347 Add 'date' handling for solr-pz2.xsl.
349 --- 1.6.33 2013/08/13
351 pz:authentication may carry user group password. If pz:authentication
352 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
353 authentication. Two forms are allowed
356 If no blanks are present, open authentication is in use (as before).
358 Fix {prev,next}recid elements that are returned by record
359 command. These were incorrect in versions 1.6.23 thru 1.6.32.
361 --- 1.6.32 2013/06/14
363 Experimental support for snippets. If argument snippets=1 is given
364 for command record or show, the text will include <match>-tags for
365 those area that matches.
367 Fix memory leak WRT client structures (incorrect inc ref count).
369 Log when a HTTP response is serialized and the time elapsed.
371 New command, service, which returns current service XML in use for
374 --- 1.6.31 2013/05/24
376 Local limit for fields of type "generic" (ie text fields) are
377 now normalized by mergekey rule before comparison takes place.
378 Before, no normalization took place and comparsion was, thus, exact.
380 New facility: dynamic rank , which allows ranking to be changed
381 for an existing result set. The rank can be set for search or
382 show. This overrides the rank for metadata elements (which fields
385 New facility:dynamic mergekey , which allows mergekey to be changed
386 for an existing result set. The mergekey can be set for search or
389 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
390 Also, allow ports to be given as names (not just integers).
391 Fix @-notation on systems that don't support IPV6 sockets.
393 --- 1.6.30 2013/04/26
395 Add MasterKey Connect configuration. Refer to section "non-standard
396 databases" for more information.
398 Allow timeformat for log to be specified with option -m (as Metaproxy
401 New Debian package pazpar2-dbg.
403 Fix NULL ptr reference of se->relevance. If a new search is initiated
404 and a CCL query fails to parse, Pazpar2 could crash.
406 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
407 existed in 1.6.29 only.
409 --- 1.6.29 2013/04/05
411 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
412 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
413 changed by setting "host" attribute for the "listen" element.
415 Change semantics of pz:extendrecs. Allow for repeated fetches .
416 pz:extendrecs is now the number of extra records to fetch (was total
419 --- 1.6.28 2013/03/21
421 Fix hang or memory violation if show occurred before a search. (not that
422 it makes much sense to perform a show before a search).
424 --- 1.6.27 2013/03/08
426 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
429 --- 1.6.26 2013/03/08
431 New pz:metadata attribute, empty="empty-value" for Pazpar2's
432 internal representation. With this attribute, Pazpar2 treates an empty
433 pz:metadata type as having the value for "empty" - if empty.
435 New setting, pz:extendrecs, which triggers extended fetch of records
436 for a database beyond pz:maxrecs for a show command.
438 Fix warning that was falsely issued for "missing limitmap".
440 Log message for Pazpart start/stop changed. Now using same style as
441 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
443 --- 1.6.25 2013/02/07
445 Fix hang of 2nd command=show with esn/syntax given.
447 --- 1.6.24 2013/01/18
449 New merge attribute type: 'first', which takes all metadata fields
450 from first target that returns the particular field.
452 --- 1.6.23 2013/01/02
454 Extend info command with hostname and YAZ SHA1
455 Indent results for both command stat and info.
457 Allow limit on merged content. The new configuration metadata
458 element, limitcluster, configures that a metadata element (name) be used
459 as limit name for search. Applies to the whole service (ie all targets),
460 unlike pz:limitmap which is configured per-target (database).
462 New feature: limitmap local:* matches against all metadata fields.
464 Allow repeated list in limitmap spec . Separated by comma. For
465 example: value="local:title,rpn:@attr 1=4".
467 New element <message> in bytarget response. Holds diagnostic message
468 of code (say 'Unsupported Use Attribute' for Bib-1 114).
470 Improved logging for record ingestion failures.
472 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
473 when YAZ is compiled without ICU support.
475 --- 1.6.22 2012/10/11
477 Requires YAZ-4.2.40 to support native solr support.
479 Fix and improve logic handling whether or not to re-do search on sort
480 order changes. A sort order with change in ascending/descending only
481 whould not trigger a new search, which is required for targets with
482 native sorting capabilities. Each client is now checked if instructions
483 (sortmap) exist for native sorting and only client that does requires
484 it is researched. Other clients is just re-ingesting the records,
485 they already have. The resultset is now cleared if any researching
488 Connection sharing between session has broken since version 1.6.8 with
489 introduction of logic that would minimize searching if pazpar2 could
490 detect this based on same query and limits and partly sort order.
491 This could lead to segementations violations.
493 Added a chapter in the manaul about relevance ranking.
495 --- 1.6.21 2012/09/24
497 Rank tweak: follow=number will increase mult by number if two terms
498 occur next to each other; number-1 if they are one term apart , .. 0
499 if they are number a part (all in order). Default is 0 (following
500 terms has no effect).
502 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
503 value given by lead and l is length from beginning of field where
504 term occurs (l=0 for first term, l=1 for second term, ..). Default
507 Rank tweak: length=strategy. length="linear" if mult is to be divided
508 by length (existing, default behavior), length="log" if mult is to be
509 divided by log2(1+length), length="none" if mult is not to be affected
512 --- 1.6.20 2012/09/21
514 Rank algorithm details may be printed as part of show response in
515 element <relevance_info>.. This is only printed if <rank debug="yes"/>
518 Record as returned by show/record command have a minimal indentation
519 which makes things human-readable.
521 New configuration of default sorting criteria (sort-default) in
522 service definition. If no criteria is defined it will be as before
525 Search command now supports sort parameter just as the show command.
526 If no parameter is give, it will use the service sort-default value.
528 --- 1.6.19 2012/09/18
530 Rank algorithm skips strings that gets normalized to empty string.
531 For example, & and ! could map to the empty string. The weight for
532 those terms is now 0 (as if they were not part of the query).
534 Rank algorithm does not use CCL from limitmap; only from the query
535 parameter (user query).
539 --- 1.6.18 2012/09/17
541 Rank algorithm configurable by 'rank' element inside service. So far
542 only, attribute 'cluster' is recognized. If cluster="yes", multiple
543 records inside a cluster boosts higher than single records. This
544 is default behavior and existing behavior. cluster="no" takes the
545 average score of each record in a cluster.
547 --- 1.6.17 2012/09/05
549 Fix bad re-use of connections (connections with changing proxy should not
552 --- 1.6.16 2012/08/22
554 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
555 resultset and sorting when the sort order is position. However this will be done on
556 every client poll, which will make pazpar2 continuing reset and fetching.
557 It should only be done on FIRST request where the sort order change.
559 Fix an issue on suggestion option: Also disable suggestions on empty string.
561 Clean up in turbo marc stylesheet.
563 Remove the hardcoded size of termlists.
565 --- 1.6.15 2012/06/27
567 New facility: ccldirective may be given in service definition. Allows
568 CCL parsing to be customized a bit, such as defining names of operators
571 New facility: raw record by checksum, rather than offset. The record
572 command optionally takes checksum which identifies certain record from
575 New facility: per field ranking. Rank may be given as M [F N] where
576 M is default rank and N is rank for CCL terms from field F.
578 --- 1.6.14 2012/06/04
580 Fix for IE7/8 in pz.js
582 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
584 Lower log level some places.
586 Remove some invalid test results.
588 --- 1.6.13 2012/05/23
590 Introducing a version=2 parameter for show, termlist and bytarget commands.
591 This enables pazpar2 to return approximation on hit and count count when
592 doing record filtering using the limit parameter on search and a
593 limitmap with a value of "local:"
595 Setting pz:xslt may embed local XSLT as an alternative to referring
597 Value is not CDATA but XML nodes embedded, so escaping is not necessary
598 but a root element *must* be present. For example:
599 <settings target="target="z3950.indexdata.com/marc">
608 Metadata field rank may given by XML internal document (pz:xslt
609 result). If rank is not given, the rank from service description is
612 Metadata field can now configured a default limitmap and facetmap.
613 Setting limitmap to "local:" would work for all kind of targets, but would
614 prob. not be the optimal solution. But at least better than the default behavior
615 of pazpar2 where no filtering is done.
617 A service definition can now also contains <set/> that defines service-wide
618 settings. These will override server-wide sets and will be overridded by
621 New setting, pz:present_chunk, that specifies number of records to fetch
622 at a time. Zero will disable chunkation; will fetch max_records at once.
624 --- 1.6.12 2012/03/14
626 Revert the format change in termlist response, that could break
627 some clients / UIs since they were expecting an (empty) element
628 if no facet values was found.
630 --- 1.6.11 2012/03/07
632 Revert the behavior of returning errors when unable to block
633 on termlist, bytarget and search, when unable to block due to
634 other block. The client will now receive a regular response,
635 but it will be logged in the server. A parameter (report) is
636 added to change behavior to return error response or WARNING
637 status message. Consider this "API" as private, as it is mostly
638 untested and could be changed in future releases.
640 Fix spell error in pz2.js fix in 1.6.10.
642 New Marc2TurboMarc.xsl (contribution from Sven Porst).
643 Can solve the missing marc21.xsl updates in some cases.
645 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
646 substring (contribtion from Sven Porst)
648 marc21.xsl: fix 1-based substring call
650 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
652 Add test_termlist_block to test suite
654 --- 1.6.10 2012/02/23
656 Fix SEGV for invalid PQFs and SRU/SOLR targets
657 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
659 Fix pz2.js: "null object" due to change in in bytarget result XML.
661 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
662 Added this normalization to the other subject-long fields (d6xx),
663 where it was missing.
665 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
666 Still differences around medium and holdings. marc21.xsl is not
667 longer active used by Index Data, and should be considered unsupported.
668 Use tmarc.xsl instead.
672 Fix SEGV that could occur for failed connections.
676 Fix bug for command sort that could return no results for active clients
677 (from previous search). This bug was present in 1.6.6-1.6.7.
679 Fix bug in results that could include results that should have been
680 filtered out. This bug was present in 1.6.6-1.6.7.
684 Fix bug introduced in 1.6.6 where a connection re-use could stall
687 Local filtering may now specify a local metadata field, eg.
688 pz:limitmap:somefield[t]=local:otherfield
692 For search, when limit and or filtering is in place and search
693 is identical to previous search, the result set is re-used and the
694 target is not searched.
696 Limits may work perform local filtering as well, by using "local:"
701 Updated bytarget command to contain a suggestions element with misspelled
702 words and suggestions to these. pz2.js has been updated to deliver this
703 onwards as well. Only target that currently delivers this is the solr
704 client in YAZ 4.2.18.
708 New service definition element, xslt, that allows an embedded stylesheet
709 to be defined. This can be referred to from pz:xslt as an alternative to
712 New pz:sortmap:field setting for specifying hints on how to make
713 a target natively sort on a field. This is used for command=show in
714 conjunction with sort.
716 New pz:url setting for specifying the actual URL for a target. When
717 this is used the target ID is not used as URL anymore and the target ID
718 may be almost any string (not including []).
720 command=termlist without name parameter returns all termlists/facets.
721 Previously if name parameter was omitted, only "subject" was returned.
725 Make termlist sorting stable. Terms with same frequency are now sorted by
726 their display name. This makes a pretty display and improves our
727 regression test because qsort is not a stable sort.
729 New sort parameter value 'position'. The 'position' sorts merged records
730 by their original position from the remote target. This is primarily useful
731 for debugging and may be used for targets that already perform some kind
732 of relevance ranking. Note that sort by default is decreasing; so to get
733 records in their original order sort=position:1 must be used.
737 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
739 Facility to change working directory for pazpar2 daemon. Option -wdir
740 sets working directory to dir. This facility is useful if core dumps
741 must be saved. In this case, the current working directory must be
742 writable by the running user, such as "nobody".
746 New configuration element <icu_chain> for <server>/<service> which
747 allows a named ICU rule (chain) to be defined. The names relevance,
748 sort, mergekey and facet are used for those operations. The definition
749 <icu_chain id="sort" locale="en"> .. </icu_chain>
751 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
752 And so on.. for relevance, mergekey and facet as well. The latter
753 style is deprecated. The facet terms are normalized by the facet
754 rule by default. This may be changed on a metadata field basis by
755 defining the new attribute 'facetrule' for the metadata element.
757 <icu_chain id="myrule" locale="en"> ... </icu_chain>
758 <metadata name="author" termlist="yes" facetrule="myrule"/>
760 Preserve rorder for merged metadata. Fixes issue as reported by Sven
761 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
763 tmarc.xsl: set journal-subpart to 773$ only.
767 Modify the behavior for the limit parameter (first defined in 1.5.7).
768 Mapping of limit searches are now defined by the new configuration item
769 pz:limitmap. Fix a dead-lock problem with the limit parameter.
771 Extend tmarc.xsl to extract 773$g data (OpenURL).
775 ICU default maps remove backquote (`).
777 Command 'search' takes limit parameter (optional). The limit parameter
778 allows a search to be limited one or more facets and the corresponding
779 values. This is for server side filtering.
781 Configure tweak: Use -lm for log(3) if needed
785 Fix a problem with skiparticle sortkey that could be completely
786 ignored (and reduced to "").
788 Fix dependency problem in pazpar2 RPM package (did not require
789 libyaz4 as it should).
793 Fix memory leak that occurred for command=termlist&name=xtargets .
795 Pazpar2 may save HTTP requests. Enabled by option -R.
799 Experimental support for DTIC DADS target. New dads-pz2.xsl.
801 Support for query_syntax (overrides the default for SRU | Z39.50)
803 Support for extraArgs (ZOOM "extraArgs" option) for targets
805 New commands: status-server and status-session
809 Fix for threaded runs: Client now have a copy of the database URL,
810 which can used after the database has been release from the client.
811 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
813 tmarc.xsl: Add journal-title-abbrev and full text.
815 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
817 Fix for cmd=record before search.
819 Session Logging clean up.
821 Fix wrong termlist factor when maxrecs is different from 100.
825 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
826 Term factor is default enabled but can be diseabled by
827 pz:termlist_term_factor=0
831 Add scaling of facet count. Currently always enabled, needs fixing.
832 Allow user-defined info for target suffix. This has no meaning in
833 Pazpar2 except to distinguish targets from each other. The suffix
834 data begins with #. For example z3950.indexdata.com/gils#Mydata
836 Added exact-match recordfilter; format name=value
840 SOLR support. Pazpar2 may operate as web service client for SOLR.
844 Fix for show command and block=1 (dead lock). Bug was introduced in
849 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
850 tested on CentOS 5.5 only.
854 Fix problem with result sets being removed from a client session
855 if the connection for it was resused by another session. Bug #3489.
857 New iphone UI for Pazpar2 (www/iphone).
861 Fixes for threaded operation.
863 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
865 New example services in etc/services in source. In the Debian packages
866 these are located in /etc/pazpar2/services-available
868 Threaded mode operational on Windows. Requires Windows 7 or Windows
871 Default value of setting pz:max_connections is 0 which means that there
872 is no limit on number of connections.
876 Pazpar2 may operate in threaded mode. Enabled by element threads in
877 the configuration. See pazpar2_conf for details.
879 New setting setting: pz:max_connections. Setting pz:max_connections is
880 a limit of number of sockets to a host. When this limit is reached,
881 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
882 The client will be marked Client_Error when it can not be searched
883 (other clients in a session may work). If pz:max_connections is not set
884 for a target, a value of 30 will be used. Note: the pz:max_connections
885 will only work in threaded mode.
887 pz2.js: JSON support for show.
889 Debian package: Enable default service, default.xml, before starting
890 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
894 Debian version depends on on libyaz4. Note that Pazpar2 will still
895 compile from source with YAZ 3.
897 Split services into separate files. The example configuration file
898 pazpar2.cfg.dist now includes a default service default.xml (part of
899 etc). And default.xml includes settings/edu.xml. The default.xml file,
900 not to be confused with settings/defaults.xml, is a template for jsdemo
901 and other services. The Debian package installs /etc/pazpar2/server.xml
902 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
903 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
904 The default.xml (from etc) is installed in /etc/pazpar2/services-available
905 and a symlink to it is created from services-enabled. The default.xml
906 service is unnamed and, thus, will be used by jsdemo and test1.
908 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
909 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
913 Support for additional fields in cf.xsl and pazpar2.conf.dist:
914 publisher, available, due, location (=locallocation), callno
915 (=callnumber), thumburl and score.
917 Describe pz:xslt and the auto setting.
919 Move mergekey definition away from the normalization stylesheets and
920 define a mergekey common for all target types in pazpar2.cfg.
922 Code update: Use the Odr_int type for hit counts. This is part of
923 YAZ 3.0.47 and later and so configure checks for that.
927 Metadata attribute 'skiparticle' also works for ICU based
928 normalization. (was only working for the non-ICU/ASCII before).
930 Command bytarget with argument settings=1 will show settings per
931 target.. This is to be able to verify correct settings and be able to
932 test that they are correct. The database settings array size is now
933 also stored.. Problems with database settings array is that if not
934 careful it will be too small (smaller than dictionary per-service
937 Make record list sorting stable by comparing mergekey for records if
938 relevance/title or other sorting criteria all match. This is merely to
939 ensure that our regressions tests works (reproducible output).
941 Relevance calculation changes: use a different denominator (length) for
942 per-field relevance scoring.. Instead of length of all ranked fields we
943 now use length of individual fields (as if they were individual "free"
944 text fields). This will ensure that documents with a long field with no
945 match (say description) will not "hurt" a title match.
947 Diagnostic member was not set on connection error. Fixed
951 Command search takes two optional parameters, startecs and maxrecs,
952 that specifies the start offset (0, 1, ...) and maximum number of records
953 to fetch for each target.
955 XSLTs + MARC maps are cached within a session so we don't re-parse
956 them over and over again. Even for a session with a single search
957 there's much to be gained because many targets use the same
960 The metadata attribute 'mergekey' now takes one of three values 'no',
961 'required', 'optional' . And the resulting mergekey from metadata
962 is now ordered in the same way as metadata in the service definition.
963 Older Pazpar2 version use the order in which metadata appeared in a
966 The search argument 'filter' now offers a new operator ~ which does a
967 substring match. The = operator works as before: string match for
968 anything but pz:id, or target match for pz:id.
970 New setting pz:recordfilter. The value of this setting takes the
971 form name[~value]. This setting makes Pazpar2 ignore all retrieved
972 records that do not have the metadata element name with value substring
975 Pazpar2 allows YAZ log level to be set (option -v).
979 For WS responses Pazpar2 creates XML header. Exception: raw record.
981 Setting XML files are now stored in etc/settings instead of etc. This
982 reflects the layout with the Debian package layout.
984 Settings may be posted for command=settings. The POSTed settings must
985 have root element 'settings' like regular setting files. In order to be
986 recognized, the POST request must use Content-Type=text/xml.
988 A service may be posted for command=init. This service will be used
989 during the session. The service may have its own target settings,
990 ICU config, timeout, etc. In order to be recognized, the POST request
991 must use Content-Type=text/xml.
993 Timeout values may be given per-service. That's element 'timeout'
994 which takes three attribute values (a subset may be given): 'session',
995 'z3950_operation', 'z3950_session'. Option -T is no longer supported
996 - used to specify session timeout.
998 Option -t tests the Pazpar2 configuration and returns exit code
999 (0=success, non-zero=failure). In previous version of Pazpar2, -t
1000 specified local settings.
1002 In version 1.2.0 the configuration file - after include processing -
1003 was dumped to stdout. Now, the configuration is only dumped to the
1004 yaz log file if option -d is given.
1006 --- 1.2.0 2009/09/10
1008 Configuration may now have multiple server areas. This means that a
1009 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
1010 yet supported - on a server basis. Configuration may also have multiple
1011 services .. That is repeating service elements inside a server. Each
1012 has an attribute 'id' which serves as service ID. This ID in turn may
1013 be used in a Pazpar2 session, by specifying parameter service=ID for
1014 command init. There can be at most one unnamed service inside a server
1015 which can be referred to by not specifying an service ID for command
1016 init (backwards compatible). In order to partition multiple servers and
1017 services a new include directive has been added. This takes an attribute
1018 'src' which specifies one or more sub-files. For example to include
1019 service files, one might use:
1020 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
1021 It is the intention that that completely makes the settings directive
1024 Fix problem where the record command would wait forever if there were
1025 no targets to wait for (activeclients == 0).
1027 --- 1.1.1 2009/08/28
1029 One result set is created per session (last search) rather than for
1030 each connection which happen to be shared (bug #3009).
1032 marc21 stylesheets changed for efficiency.
1034 --- 1.1.0 2009/08/19
1036 Session timeout may be specified on the command-line as option -T.
1038 Pazpar2 may now be operated in a no-merged mode for records.. All records
1039 will be considered unique. This mode is enabled if no mergekey is
1040 generated by the normalization stylesheet (pz:xslt).
1042 Pazpar2 caches original records from each target and the 'record' command
1043 with offset returns the original record if 'syntax' and 'esn' are NOT
1044 specified. This speeds up retrieval of original records but also means
1045 that Pazpar2 uses more memory. The cached records will be freed when the
1046 session terminates or a new search is executed.
1048 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
1049 library part of YAZ is used.
1051 Added SRU client support.
1053 Automatically computes pz:nativesyntax if not provided. Works for XML and
1056 --- 1.0.13 2008/11/24
1058 Command bytarget returns name of target (if defined).
1060 --- 1.0.12 2008/11/04
1062 Fixed bug #2021.. location now holds all brief elements.
1064 --- 1.0.11 2008/10/15
1066 Fixed check for application/x-www-form-urlencoded parameters.
1068 --- 1.0.10 2008/10/14
1070 Fixes for IE in pz2.js.
1072 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
1074 --- 1.0.9 2008/05/23
1076 Changed the JS library pz2.js to use POST for long URL (+ params).
1078 Added installation instructions for Windows. Note: NT services is
1079 NOT available until we make a new release of YAZ.
1081 Preserve order of repeated metadata fields (they were reversed before).
1083 More MARC21 information extracted for metadata.
1085 --- 1.0.8 2008/04/22
1087 Fixed bug #1162: HTML entities are not escaped properly.
1089 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
1091 --- 1.0.7 2008/04/14
1093 Marc21 stylesheet updated to reflect multiple full text fields
1095 --- 1.0.6 2008/03/12
1097 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1099 Fixed bug 2100: Database wildcards not working
1101 --- 1.0.5 2007/11/09
1103 Added support for retrieval of records in binary.
1105 Fixed bug 1794: Pazpar2 does not return valid XML.
1107 Deal with ICU not returning sortkey (resulted in SEGV before).
1109 --- 1.0.4 2007/09/28
1111 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1112 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1114 Improved diagnostics when Pazpar2 HTTP decoding fails.
1116 Pazpar2 requests may be POSTed as using Content-Type
1117 application/x-www-form-urlencoded.
1119 Pazpar2 honors LF in HTTP headers.
1121 Handle targets that handle negative hit counts (should not happen, but it
1124 --- 1.0.3 2007/09/19
1126 ICU is used for tokenization and normalization of the following: mergekey,
1127 sorting, relevance terms.
1129 Debian package now enables ICU tokenization and normalization by default.
1131 --- 1.0.2 2007/08/22
1133 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1134 ways: Either as parameters to the normalization stylesheets (which would allow the
1135 programmer to postprocess or use the values in any way) or after the normalization
1136 step, in which case values are made part of the normalized record (and available for
1137 sorting, termlists, display, or other interface-related use.
1139 Implemented sorting by year.
1141 Option -d dumps records to the current log file instead of stderr.
1143 Fixes for compilation on cygwin.
1145 Z39.50 client code uses pz:elements. pz:elements was recognized in
1146 earlier Pazpar2 versions but it was not used for anything.
1148 icu_chain_test is using fgets instead of getline - fixes compilation
1151 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1152 query conversions fail (rather than _any_). This means targets that do
1153 not support some fields are ignored in a search.
1155 --- 1.0.1 2007/07/03
1157 Improved handling of socket timeout for Z39.50 connections.
1159 Misc documentation updates and spell fixes.
1161 Debian package pazpar2 creates log rotate entry.
1163 Debian package pazpar2-apache2 reloads Apache2.
1165 jsdemo included in distribution. It illustrates the use of the js/pz2.js
1168 --- 1.0.0 2007/06/20
1170 First public release.
