3 Fix PAZ-1015, which prevented the docs from being built, and therefore
4 the whole package from being released.
8 Fix PAZ-1009: Do not create local facets when using facetmap:split
12 Facet ID term map PAZ-1008
13 New setting pz:facetmap:split:name (refer to documentation)
17 Sort by retrieval PAZ-1006
18 Allows sorting by order that records were retrieved from databases.
20 Response from bytarget command includes native query PAZ-1005
22 Use lx2.loc.gov:210/LCDB_MARC8 instd of z3950.loc.gov:7090/voyager PAZ-1003
26 New metadata facility "icurule" for normalizing metadata text PAZ-1002
27 This allows ICU normalization of text before in-cluster merging takes
30 Heuristics to deal with Primo s/e/page PAZ-1001
32 Fix test_limit_limitmap fails PAZ-1000
36 Limitmap ccl: deal with quotes and backslash PAZ-999
38 Handle date range from a limit parameter PAZ-997
39 The CCL term is not quoted unless it includes blanks. This will ensure
40 that r=r is handled correctly. This changes behavior a bit. If term
41 should not be converted to @and, then instead of r=r one should use
44 Construct md-pages-number form page/endpage PAZ-998
48 solr-pz2.xsl: extend Solr transformation to emit license_name field PAZ-996
50 cf.xsl: forwards flat affiliation structure PAZ-992
52 parpar2: log YAZ version upon start PAZ-993
54 Update and fix documentation for preferred targets
56 Fix spelling of present_chunk in documentation
60 Increase facet limit PAZ-990
61 No longer a limit on facets.
63 Pazpar2-js no longer requires Apache2 PAZ-989
64 Package pazpar2-apache2 sets up everything WRT apache and only
65 package which requires it. pazpar2-apache depends on pazpar2-js.
69 Larger string buffer for forward address PAZ-987
70 Fixes buffer overflow that could occur if forward address is IPV6.
72 Updates to Windows NMAKE makefile for Visual Studio 2013.
76 Use YAZ backtrace facility PAZ-983. In case of crashes YAZ log may
77 include more details about the fault. Better install gdb and the
78 debug version of pazpar2 (pazpar2-dbg on Debian/Ubuntu).
80 Per target timeout PAZ-981
81 New setting pz:timeout which overrides z3950_operation timeout
86 Re-introduce journal-subpart PAZ-980
87 Both citation and journal-subpart have same value.
91 Add Ubuntu utopic 14.04 and Ubuntu saucy 13.10 to the list of packages
94 Remove from js/pz2.js the code that translates just two diagnostic
95 codes (1 and 2) into human-readable messages. This is no longer
96 necessary at all, as PazPar2 has been returning the message as well as
97 the code in its responses since December 2012. Fixes PAZ-978.
99 primo xsl produces citation rather than journal-subpart PAZ-972
100 (fix in 1.8.1 was incorrect)
102 Fix missing .url files PAZ-977
103 Add missing .url+.cfg and add proper check for it.
107 Turbomarc needs number check for date 903 map PAZ-973
109 primo-pz2.xsl creates citation rather than journal-subpart PAZ-972
111 pz2.js: on successful search, issue a "show" command only if a show
112 callback function has been installed. Fixes part of PAZ-975
116 New command=stop which stops further search&retrieval for active
119 CF/primo XSL generates {volume,issue,pages}-number that are defined
120 in default Pazpar2 service definition. PAZ-968 PAZ-970
124 Various fixes for threaded operation PAZ-960 thru PAZ-966
126 Dump main configuration file during start of Pazpar2 PAZ-957
130 Log ingest failures and record failures:
132 Clean up logging PAZ-942
133 Use session lead in more places. Log hits/records/filtered for each
134 target when fetching is complete. Log hit count when a search
135 (response) is received. Remove some less useful log messages.
137 Fix warning about about missing (internal) stylesheet PAZ-956
139 Report number of filtered records in bytarget PAZ-954
141 Cache XML documents as they appear after normalization. The key
142 for the cache is database+record offset. Cache is removed if query
143 is modified for search. This speeds up re-establishing a result set
144 for databases where new query is same previous query.
148 poll: add assert for number of FDs; abort on poll failure
152 Fix hang for 2nd use of target with unresolved DNS PAZ-949
156 Use poll rather than select for main event loop to overcome limit of
157 1024 file descriptors PAZ-947
159 Override setting with same name (do not append) PAZ-945
163 Separate package: pazpar2-xsl PAZ-932
165 --- 1.6.44 2014/06/27
167 Update OPAC stylesheets for availabilityDate PAZ-943
169 Fix too funny startrecs description
171 Fix broken ~ match if filter contains = PAZ-941
173 --- 1.6.43 2014/06/12
175 Add pz:redis option for ZOOM caching using redis. This is an alternative
176 to memcached. Requires YAZ 5.2.0 to work.
178 --- 1.6.42 2014/05/06
180 Re-ingest native facets PAZ-934
182 Fix medium override for solr-pz2.xsl.
184 --- 1.6.41 2014/04/23
186 Fix URL with leading http:// not working PAZ-933
188 Build packages for Ubuntu Trusty Tahr 14.04 LTS
190 cf.xsl: handle medium override AND md field
192 --- 1.6.40 2014/04/10
194 sortmap relevance always uses increasing=1. PAZ-930
196 solr-pz2.xsl: ensure medium is also applied if Solr record do not
199 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
200 this code is only executed once.
202 Fix typos is sortmap documentation.
204 Doc: fix misplaced variablelist tag.
206 --- 1.6.39 2014/02/19
208 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
209 It's been like that since version 1.1.1 from August 2009.
211 Add support for result-set caching via memcached. See description of
212 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
214 Add support for a <metadata> container tag. Patfh from Sven Porst.
216 Add support for XInclude in main configuarion file. Patch from Sven Porst.
218 Add client_{lock,unlock} before call to non_block_events in
219 connection_continue. Problem is that if non_block_events fire records,
220 then we will not unlock client at all. And as a result, a dead-lock
223 --- 1.6.38 2014/01/07
225 Avoid removing slash and other characters for generic metadata that
226 looks like a URL (contains ://). PAZ-915
228 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
230 Cluster merge fixes. PAZ-901
232 Set client state to "working" when waiting for DNS resolver. PAZ-907
234 Log when session terminates. PAZ-905
236 Fix LSB/HS conformance for /etc/init.d/pazpar2 PAZ-904
237 Debian: add support for /etc/init.d/pazpar2 status
239 --- 1.6.37 2013/11/18
241 Fix 'Record Missing' for command=show PAZ-903
243 Preserve order of records within cluster PAZ-902
245 testing: use yaz-ztest -V if possible and use YAZ in sibling directory
248 Allow clustered records to be ingested during retrieval. PAZ-900
250 Fix void function error which cannot return a value.
252 --- 1.6.36 2013/11/11
254 SRU pz:authentication="a/b" may end up as x-username=a%2Fb PAZ-899
256 Upgrade to debhelper version 7 PAZ-898
258 Package with libyaz5 PAZ-897
260 Better error message for CCL parse errors PAZ-887
262 --- 1.6.35 2013/09/23
264 New target setting: pz:authentication_mode. PAZ-896
266 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
268 Strip #-suffix for ZOOM URLs. PAZ-892
270 --- 1.6.34 2013/08/30
272 Fix issue with hanging show/bytarget. Could happen if new search was
273 fired with filter before show from previous show completed.
275 Add 'date' handling for solr-pz2.xsl.
277 --- 1.6.33 2013/08/13
279 pz:authentication may carry user group password. If pz:authentication
280 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
281 authentication. Two forms are allowed
284 If no blanks are present, open authentication is in use (as before).
286 Fix {prev,next}recid elements that are returned by record
287 command. These were incorrect in versions 1.6.23 thru 1.6.32.
289 --- 1.6.32 2013/06/14
291 Experimental support for snippets. If argument snippets=1 is given
292 for command record or show, the text will include <match>-tags for
293 those area that matches.
295 Fix memory leak WRT client structures (incorrect inc ref count).
297 Log when a HTTP response is serialized and the time elapsed.
299 New command, service, which returns current service XML in use for
302 --- 1.6.31 2013/05/24
304 Local limit for fields of type "generic" (ie text fields) are
305 now normalized by mergekey rule before comparison takes place.
306 Before, no normalization took place and comparsion was, thus, exact.
308 New facility: dynamic rank , which allows ranking to be changed
309 for an existing result set. The rank can be set for search or
310 show. This overrides the rank for metadata elements (which fields
313 New facility:dynamic mergekey , which allows mergekey to be changed
314 for an existing result set. The mergekey can be set for search or
317 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
318 Also, allow ports to be given as names (not just integers).
319 Fix @-notation on systems that don't support IPV6 sockets.
321 --- 1.6.30 2013/04/26
323 Add MasterKey Connect configuration. Refer to section "non-standard
324 databases" for more information.
326 Allow timeformat for log to be specified with option -m (as Metaproxy
329 New Debian package pazpar2-dbg.
331 Fix NULL ptr reference of se->relevance. If a new search is initiated
332 and a CCL query fails to parse, Pazpar2 could crash.
334 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
335 existed in 1.6.29 only.
337 --- 1.6.29 2013/04/05
339 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
340 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
341 changed by setting "host" attribute for the "listen" element.
343 Change semantics of pz:extendrecs. Allow for repeated fetches .
344 pz:extendrecs is now the number of extra records to fetch (was total
347 --- 1.6.28 2013/03/21
349 Fix hang or memory violation if show occurred before a search. (not that
350 it makes much sense to perform a show before a search).
352 --- 1.6.27 2013/03/08
354 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
357 --- 1.6.26 2013/03/08
359 New pz:metadata attribute, empty="empty-value" for Pazpar2's
360 internal representation. With this attribute, Pazpar2 treates an empty
361 pz:metadata type as having the value for "empty" - if empty.
363 New setting, pz:extendrecs, which triggers extended fetch of records
364 for a database beyond pz:maxrecs for a show command.
366 Fix warning that was falsely issued for "missing limitmap".
368 Log message for Pazpart start/stop changed. Now using same style as
369 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
371 --- 1.6.25 2013/02/07
373 Fix hang of 2nd command=show with esn/syntax given.
375 --- 1.6.24 2013/01/18
377 New merge attribute type: 'first', which takes all metadata fields
378 from first target that returns the particular field.
380 --- 1.6.23 2013/01/02
382 Extend info command with hostname and YAZ SHA1
383 Indent results for both command stat and info.
385 Allow limit on merged content. The new configuration metadata
386 element, limitcluster, configures that a metadata element (name) be used
387 as limit name for search. Applies to the whole service (ie all targets),
388 unlike pz:limitmap which is configured per-target (database).
390 New feature: limitmap local:* matches against all metadata fields.
392 Allow repeated list in limitmap spec . Separated by comma. For
393 example: value="local:title,rpn:@attr 1=4".
395 New element <message> in bytarget response. Holds diagnostic message
396 of code (say 'Unsupported Use Attribute' for Bib-1 114).
398 Improved logging for record ingestion failures.
400 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
401 when YAZ is compiled without ICU support.
403 --- 1.6.22 2012/10/11
405 Requires YAZ-4.2.40 to support native solr support.
407 Fix and improve logic handling whether or not to re-do search on sort
408 order changes. A sort order with change in ascending/descending only
409 whould not trigger a new search, which is required for targets with
410 native sorting capabilities. Each client is now checked if instructions
411 (sortmap) exist for native sorting and only client that does requires
412 it is researched. Other clients is just re-ingesting the records,
413 they already have. The resultset is now cleared if any researching
416 Connection sharing between session has broken since version 1.6.8 with
417 introduction of logic that would minimize searching if pazpar2 could
418 detect this based on same query and limits and partly sort order.
419 This could lead to segementations violations.
421 Added a chapter in the manaul about relevance ranking.
423 --- 1.6.21 2012/09/24
425 Rank tweak: follow=number will increase mult by number if two terms
426 occur next to each other; number-1 if they are one term apart , .. 0
427 if they are number a part (all in order). Default is 0 (following
428 terms has no effect).
430 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
431 value given by lead and l is length from beginning of field where
432 term occurs (l=0 for first term, l=1 for second term, ..). Default
435 Rank tweak: length=strategy. length="linear" if mult is to be divided
436 by length (existing, default behavior), length="log" if mult is to be
437 divided by log2(1+length), length="none" if mult is not to be affected
440 --- 1.6.20 2012/09/21
442 Rank algorithm details may be printed as part of show response in
443 element <relevance_info>.. This is only printed if <rank debug="yes"/>
446 Record as returned by show/record command have a minimal indentation
447 which makes things human-readable.
449 New configuration of default sorting criteria (sort-default) in
450 service definition. If no criteria is defined it will be as before
453 Search command now supports sort parameter just as the show command.
454 If no parameter is give, it will use the service sort-default value.
456 --- 1.6.19 2012/09/18
458 Rank algorithm skips strings that gets normalized to empty string.
459 For example, & and ! could map to the empty string. The weight for
460 those terms is now 0 (as if they were not part of the query).
462 Rank algorithm does not use CCL from limitmap; only from the query
463 parameter (user query).
467 --- 1.6.18 2012/09/17
469 Rank algorithm configurable by 'rank' element inside service. So far
470 only, attribute 'cluster' is recognized. If cluster="yes", multiple
471 records inside a cluster boosts higher than single records. This
472 is default behavior and existing behavior. cluster="no" takes the
473 average score of each record in a cluster.
475 --- 1.6.17 2012/09/05
477 Fix bad re-use of connections (connections with changing proxy should not
480 --- 1.6.16 2012/08/22
482 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
483 resultset and sorting when the sort order is position. However this will be done on
484 every client poll, which will make pazpar2 continuing reset and fetching.
485 It should only be done on FIRST request where the sort order change.
487 Fix an issue on suggestion option: Also disable suggestions on empty string.
489 Clean up in turbo marc stylesheet.
491 Remove the hardcoded size of termlists.
493 --- 1.6.15 2012/06/27
495 New facility: ccldirective may be given in service definition. Allows
496 CCL parsing to be customized a bit, such as defining names of operators
499 New facility: raw record by checksum, rather than offset. The record
500 command optionally takes checksum which identifies certain record from
503 New facility: per field ranking. Rank may be given as M [F N] where
504 M is default rank and N is rank for CCL terms from field F.
506 --- 1.6.14 2012/06/04
508 Fix for IE7/8 in pz.js
510 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
512 Lower log level some places.
514 Remove some invalid test results.
516 --- 1.6.13 2012/05/23
518 Introducing a version=2 parameter for show, termlist and bytarget commands.
519 This enables pazpar2 to return approximation on hit and count count when
520 doing record filtering using the limit parameter on search and a
521 limitmap with a value of "local:"
523 Setting pz:xslt may embed local XSLT as an alternative to referring
525 Value is not CDATA but XML nodes embedded, so escaping is not necessary
526 but a root element *must* be present. For example:
527 <settings target="target="z3950.indexdata.com/marc">
536 Metadata field rank may given by XML internal document (pz:xslt
537 result). If rank is not given, the rank from service description is
540 Metadata field can now configured a default limitmap and facetmap.
541 Setting limitmap to "local:" would work for all kind of targets, but would
542 prob. not be the optimal solution. But at least better than the default behavior
543 of pazpar2 where no filtering is done.
545 A service definition can now also contains <set/> that defines service-wide
546 settings. These will override server-wide sets and will be overridded by
549 New setting, pz:present_chunk, that specifies number of records to fetch
550 at a time. Zero will disable chunkation; will fetch max_records at once.
552 --- 1.6.12 2012/03/14
554 Revert the format change in termlist response, that could break
555 some clients / UIs since they were expecting an (empty) element
556 if no facet values was found.
558 --- 1.6.11 2012/03/07
560 Revert the behavior of returning errors when unable to block
561 on termlist, bytarget and search, when unable to block due to
562 other block. The client will now receive a regular response,
563 but it will be logged in the server. A parameter (report) is
564 added to change behavior to return error response or WARNING
565 status message. Consider this "API" as private, as it is mostly
566 untested and could be changed in future releases.
568 Fix spell error in pz2.js fix in 1.6.10.
570 New Marc2TurboMarc.xsl (contribution from Sven Porst).
571 Can solve the missing marc21.xsl updates in some cases.
573 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
574 substring (contribtion from Sven Porst)
576 marc21.xsl: fix 1-based substring call
578 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
580 Add test_termlist_block to test suite
582 --- 1.6.10 2012/02/23
584 Fix SEGV for invalid PQFs and SRU/SOLR targets
585 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
587 Fix pz2.js: "null object" due to change in in bytarget result XML.
589 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
590 Added this normalization to the other subject-long fields (d6xx),
591 where it was missing.
593 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
594 Still differences around medium and holdings. marc21.xsl is not
595 longer active used by Index Data, and should be considered unsupported.
596 Use tmarc.xsl instead.
600 Fix SEGV that could occur for failed connections.
604 Fix bug for command sort that could return no results for active clients
605 (from previous search). This bug was present in 1.6.6-1.6.7.
607 Fix bug in results that could include results that should have been
608 filtered out. This bug was present in 1.6.6-1.6.7.
612 Fix bug introduced in 1.6.6 where a connection re-use could stall
615 Local filtering may now specify a local metadata field, eg.
616 pz:limitmap:somefield[t]=local:otherfield
620 For search, when limit and or filtering is in place and search
621 is identical to previous search, the result set is re-used and the
622 target is not searched.
624 Limits may work perform local filtering as well, by using "local:"
629 Updated bytarget command to contain a suggestions element with misspelled
630 words and suggestions to these. pz2.js has been updated to deliver this
631 onwards as well. Only target that currently delivers this is the solr
632 client in YAZ 4.2.18.
636 New service definition element, xslt, that allows an embedded stylesheet
637 to be defined. This can be referred to from pz:xslt as an alternative to
640 New pz:sortmap:field setting for specifying hints on how to make
641 a target natively sort on a field. This is used for command=show in
642 conjunction with sort.
644 New pz:url setting for specifying the actual URL for a target. When
645 this is used the target ID is not used as URL anymore and the target ID
646 may be almost any string (not including []).
648 command=termlist without name parameter returns all termlists/facets.
649 Previously if name parameter was omitted, only "subject" was returned.
653 Make termlist sorting stable. Terms with same frequency are now sorted by
654 their display name. This makes a pretty display and improves our
655 regression test because qsort is not a stable sort.
657 New sort parameter value 'position'. The 'position' sorts merged records
658 by their original position from the remote target. This is primarily useful
659 for debugging and may be used for targets that already perform some kind
660 of relevance ranking. Note that sort by default is decreasing; so to get
661 records in their original order sort=position:1 must be used.
665 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
667 Facility to change working directory for pazpar2 daemon. Option -wdir
668 sets working directory to dir. This facility is useful if core dumps
669 must be saved. In this case, the current working directory must be
670 writable by the running user, such as "nobody".
674 New configuration element <icu_chain> for <server>/<service> which
675 allows a named ICU rule (chain) to be defined. The names relevance,
676 sort, mergekey and facet are used for those operations. The definition
677 <icu_chain id="sort" locale="en"> .. </icu_chain>
679 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
680 And so on.. for relevance, mergekey and facet as well. The latter
681 style is deprecated. The facet terms are normalized by the facet
682 rule by default. This may be changed on a metadata field basis by
683 defining the new attribute 'facetrule' for the metadata element.
685 <icu_chain id="myrule" locale="en"> ... </icu_chain>
686 <metadata name="author" termlist="yes" facetrule="myrule"/>
688 Preserve rorder for merged metadata. Fixes issue as reported by Sven
689 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
691 tmarc.xsl: set journal-subpart to 773$ only.
695 Modify the behavior for the limit parameter (first defined in 1.5.7).
696 Mapping of limit searches are now defined by the new configuration item
697 pz:limitmap. Fix a dead-lock problem with the limit parameter.
699 Extend tmarc.xsl to extract 773$g data (OpenURL).
703 ICU default maps remove backquote (`).
705 Command 'search' takes limit parameter (optional). The limit parameter
706 allows a search to be limited one or more facets and the corresponding
707 values. This is for server side filtering.
709 Configure tweak: Use -lm for log(3) if needed
713 Fix a problem with skiparticle sortkey that could be completely
714 ignored (and reduced to "").
716 Fix dependency problem in pazpar2 RPM package (did not require
717 libyaz4 as it should).
721 Fix memory leak that occurred for command=termlist&name=xtargets .
723 Pazpar2 may save HTTP requests. Enabled by option -R.
727 Experimental support for DTIC DADS target. New dads-pz2.xsl.
729 Support for query_syntax (overrides the default for SRU | Z39.50)
731 Support for extraArgs (ZOOM "extraArgs" option) for targets
733 New commands: status-server and status-session
737 Fix for threaded runs: Client now have a copy of the database URL,
738 which can used after the database has been release from the client.
739 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
741 tmarc.xsl: Add journal-title-abbrev and full text.
743 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
745 Fix for cmd=record before search.
747 Session Logging clean up.
749 Fix wrong termlist factor when maxrecs is different from 100.
753 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
754 Term factor is default enabled but can be diseabled by
755 pz:termlist_term_factor=0
759 Add scaling of facet count. Currently always enabled, needs fixing.
760 Allow user-defined info for target suffix. This has no meaning in
761 Pazpar2 except to distinguish targets from each other. The suffix
762 data begins with #. For example z3950.indexdata.com/gils#Mydata
764 Added exact-match recordfilter; format name=value
768 SOLR support. Pazpar2 may operate as web service client for SOLR.
772 Fix for show command and block=1 (dead lock). Bug was introduced in
777 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
778 tested on CentOS 5.5 only.
782 Fix problem with result sets being removed from a client session
783 if the connection for it was resused by another session. Bug #3489.
785 New iphone UI for Pazpar2 (www/iphone).
789 Fixes for threaded operation.
791 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
793 New example services in etc/services in source. In the Debian packages
794 these are located in /etc/pazpar2/services-available
796 Threaded mode operational on Windows. Requires Windows 7 or Windows
799 Default value of setting pz:max_connections is 0 which means that there
800 is no limit on number of connections.
804 Pazpar2 may operate in threaded mode. Enabled by element threads in
805 the configuration. See pazpar2_conf for details.
807 New setting setting: pz:max_connections. Setting pz:max_connections is
808 a limit of number of sockets to a host. When this limit is reached,
809 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
810 The client will be marked Client_Error when it can not be searched
811 (other clients in a session may work). If pz:max_connections is not set
812 for a target, a value of 30 will be used. Note: the pz:max_connections
813 will only work in threaded mode.
815 pz2.js: JSON support for show.
817 Debian package: Enable default service, default.xml, before starting
818 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
822 Debian version depends on on libyaz4. Note that Pazpar2 will still
823 compile from source with YAZ 3.
825 Split services into separate files. The example configuration file
826 pazpar2.cfg.dist now includes a default service default.xml (part of
827 etc). And default.xml includes settings/edu.xml. The default.xml file,
828 not to be confused with settings/defaults.xml, is a template for jsdemo
829 and other services. The Debian package installs /etc/pazpar2/server.xml
830 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
831 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
832 The default.xml (from etc) is installed in /etc/pazpar2/services-available
833 and a symlink to it is created from services-enabled. The default.xml
834 service is unnamed and, thus, will be used by jsdemo and test1.
836 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
837 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
841 Support for additional fields in cf.xsl and pazpar2.conf.dist:
842 publisher, available, due, location (=locallocation), callno
843 (=callnumber), thumburl and score.
845 Describe pz:xslt and the auto setting.
847 Move mergekey definition away from the normalization stylesheets and
848 define a mergekey common for all target types in pazpar2.cfg.
850 Code update: Use the Odr_int type for hit counts. This is part of
851 YAZ 3.0.47 and later and so configure checks for that.
855 Metadata attribute 'skiparticle' also works for ICU based
856 normalization. (was only working for the non-ICU/ASCII before).
858 Command bytarget with argument settings=1 will show settings per
859 target.. This is to be able to verify correct settings and be able to
860 test that they are correct. The database settings array size is now
861 also stored.. Problems with database settings array is that if not
862 careful it will be too small (smaller than dictionary per-service
865 Make record list sorting stable by comparing mergekey for records if
866 relevance/title or other sorting criteria all match. This is merely to
867 ensure that our regressions tests works (reproducible output).
869 Relevance calculation changes: use a different denominator (length) for
870 per-field relevance scoring.. Instead of length of all ranked fields we
871 now use length of individual fields (as if they were individual "free"
872 text fields). This will ensure that documents with a long field with no
873 match (say description) will not "hurt" a title match.
875 Diagnostic member was not set on connection error. Fixed
879 Command search takes two optional parameters, startecs and maxrecs,
880 that specifies the start offset (0, 1, ...) and maximum number of records
881 to fetch for each target.
883 XSLTs + MARC maps are cached within a session so we don't re-parse
884 them over and over again. Even for a session with a single search
885 there's much to be gained because many targets use the same
888 The metadata attribute 'mergekey' now takes one of three values 'no',
889 'required', 'optional' . And the resulting mergekey from metadata
890 is now ordered in the same way as metadata in the service definition.
891 Older Pazpar2 version use the order in which metadata appeared in a
894 The search argument 'filter' now offers a new operator ~ which does a
895 substring match. The = operator works as before: string match for
896 anything but pz:id, or target match for pz:id.
898 New setting pz:recordfilter. The value of this setting takes the
899 form name[~value]. This setting makes Pazpar2 ignore all retrieved
900 records that do not have the metadata element name with value substring
903 Pazpar2 allows YAZ log level to be set (option -v).
907 For WS responses Pazpar2 creates XML header. Exception: raw record.
909 Setting XML files are now stored in etc/settings instead of etc. This
910 reflects the layout with the Debian package layout.
912 Settings may be posted for command=settings. The POSTed settings must
913 have root element 'settings' like regular setting files. In order to be
914 recognized, the POST request must use Content-Type=text/xml.
916 A service may be posted for command=init. This service will be used
917 during the session. The service may have its own target settings,
918 ICU config, timeout, etc. In order to be recognized, the POST request
919 must use Content-Type=text/xml.
921 Timeout values may be given per-service. That's element 'timeout'
922 which takes three attribute values (a subset may be given): 'session',
923 'z3950_operation', 'z3950_session'. Option -T is no longer supported
924 - used to specify session timeout.
926 Option -t tests the Pazpar2 configuration and returns exit code
927 (0=success, non-zero=failure). In previous version of Pazpar2, -t
928 specified local settings.
930 In version 1.2.0 the configuration file - after include processing -
931 was dumped to stdout. Now, the configuration is only dumped to the
932 yaz log file if option -d is given.
936 Configuration may now have multiple server areas. This means that a
937 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
938 yet supported - on a server basis. Configuration may also have multiple
939 services .. That is repeating service elements inside a server. Each
940 has an attribute 'id' which serves as service ID. This ID in turn may
941 be used in a Pazpar2 session, by specifying parameter service=ID for
942 command init. There can be at most one unnamed service inside a server
943 which can be referred to by not specifying an service ID for command
944 init (backwards compatible). In order to partition multiple servers and
945 services a new include directive has been added. This takes an attribute
946 'src' which specifies one or more sub-files. For example to include
947 service files, one might use:
948 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
949 It is the intention that that completely makes the settings directive
952 Fix problem where the record command would wait forever if there were
953 no targets to wait for (activeclients == 0).
957 One result set is created per session (last search) rather than for
958 each connection which happen to be shared (bug #3009).
960 marc21 stylesheets changed for efficiency.
964 Session timeout may be specified on the command-line as option -T.
966 Pazpar2 may now be operated in a no-merged mode for records.. All records
967 will be considered unique. This mode is enabled if no mergekey is
968 generated by the normalization stylesheet (pz:xslt).
970 Pazpar2 caches original records from each target and the 'record' command
971 with offset returns the original record if 'syntax' and 'esn' are NOT
972 specified. This speeds up retrieval of original records but also means
973 that Pazpar2 uses more memory. The cached records will be freed when the
974 session terminates or a new search is executed.
976 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
977 library part of YAZ is used.
979 Added SRU client support.
981 Automatically computes pz:nativesyntax if not provided. Works for XML and
984 --- 1.0.13 2008/11/24

1002 --- 1.0.9 2008/05/23
1004 Changed the JS library pz2.js to use POST for long URL (+ params).
1006 Added installation instructions for Windows. Note: NT services is
1007 NOT available until we make a new release of YAZ.
1009 Preserve order of repeated metadata fields (they were reversed before).
1011 More MARC21 information extracted for metadata.

1023 --- 1.0.6 2008/03/12
1025 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1027 Fixed bug 2100: Database wildcards not working
1029 --- 1.0.5 2007/11/09
1031 Added support for retrieval of records in binary.
1033 Fixed bug 1794: Pazpar2 does not return valid XML.
1035 Deal with ICU not returning sortkey (resulted in SEGV before).
1037 --- 1.0.4 2007/09/28
1039 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1040 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1042 Improved diagnostics when Pazpar2 HTTP decoding fails.
1044 Pazpar2 requests may be POSTed as using Content-Type
1045 application/x-www-form-urlencoded.
1047 Pazpar2 honors LF in HTTP headers.
1049 Handle targets that handle negative hit counts (should not happen, but it
1052 --- 1.0.3 2007/09/19
1054 ICU is used for tokenization and normalization of the following: mergekey,
1055 sorting, relevance terms.
1057 Debian package now enables ICU tokenization and normalization by default.
1059 --- 1.0.2 2007/08/22
1061 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1062 ways: Either as parameters to the normalization stylesheets (which would allow the
1063 programmer to postprocess or use the values in any way) or after the normalization
1064 step, in which case values are made part of the normalized record (and available for
1065 sorting, termlists, display, or other interface-related use.
1067 Implemented sorting by year.
1069 Option -d dumps records to the current log file instead of stderr.
1071 Fixes for compilation on cygwin.
1073 Z39.50 client code uses pz:elements. pz:elements was recognized in
1074 earlier Pazpar2 versions but it was not used for anything.
1076 icu_chain_test is using fgets instead of getline - fixes compilation
1079 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1080 query conversions fail (rather than _any_). This means targets that do
1081 not support some fields are ignored in a search.
1083 --- 1.0.1 2007/07/03
1085 Improved handling of socket timeout for Z39.50 connections.
1087 Misc documentation updates and spell fixes.
1089 Debian package pazpar2 creates log rotate entry.
1091 Debian package pazpar2-apache2 reloads Apache2.
1093 jsdemo included in distribution. It illustrates the use of the js/pz2.js
