1 --- 1.8.1 [IN PROGRESS]
3 pz2.js: on successful search, issue a "show" command only if a show
4 callback function has been installed. Fixes part of MKWS-284.
8 New command=stop which stops further search&retrieval for active
11 CF/primo XSL generates {volume,issue,pages}-number that are defined
12 in default Pazpar2 service definition. PAZ-968 PAZ-970
16 Various fixes for threaded operation PAZ-960 thru PAZ-966
18 Dump main configuration file during start of Pazpar2 PAZ-957
22 Log ingest failures and record failures:
24 Clean up logging PAZ-942
25 Use session lead in more places. Log hits/records/filtered for each
26 target when fetching is complete. Log hit count when a search
27 (response) is received. Remove some less useful log messages.
29 Fix warning about about missing (internal) stylesheet PAZ-956
31 Report number of filtered records in bytarget PAZ-954
33 Cache XML documents as they appear after normalization. The key
34 for the cache is database+record offset. Cache is removed if query
35 is modified for search. This speeds up re-establishing a result set
36 for databases where new query is same previous query.
40 poll: add assert for number of FDs; abort on poll failure
44 Fix hang for 2nd use of target with unresolved DNS PAZ-949
48 Use poll rather than select for main event loop to overcome limit of
49 1024 file descriptors PAZ-947
51 Override setting with same name (do not append) PAZ-945
55 Separate package: pazpar2-xsl PAZ-932
59 Update OPAC stylesheets for availabilityDate PAZ-943
61 Fix too funny startrecs description
63 Fix broken ~ match if filter contains = PAZ-941
67 Add pz:redis option for ZOOM caching using redis. This is an alternative
68 to memcached. Requires YAZ 5.2.0 to work.
72 Re-ingest native facets PAZ-934
74 Fix medium override for solr-pz2.xsl.
78 Fix URL with leading http:// not working PAZ-933
80 Build packages for Ubuntu Trusty Tahr 14.04 LTS
82 cf.xsl: handle medium override AND md field
86 sortmap relevance always uses increasing=1. PAZ-930
88 solr-pz2.xsl: ensure medium is also applied if Solr record do not
91 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
92 this code is only executed once.
94 Fix typos is sortmap documentation.
96 Doc: fix misplaced variablelist tag.
100 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
101 It's been like that since version 1.1.1 from August 2009.
103 Add support for result-set caching via memcached. See description of
104 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
106 Add support for a <metadata> container tag. Patfh from Sven Porst.
108 Add support for XInclude in main configuarion file. Patch from Sven Porst.
110 Add client_{lock,unlock} before call to non_block_events in
111 connection_continue. Problem is that if non_block_events fire records,
112 then we will not unlock client at all. And as a result, a dead-lock
115 --- 1.6.38 2014/01/07
117 Avoid removing slash and other characters for generic metadata that
118 looks like a URL (contains ://). PAZ-915
120 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
122 Cluster merge fixes. PAZ-901
124 Set client state to "working" when waiting for DNS resolver. PAZ-907
126 Log when session terminates. PAZ-905
128 Fix LSB/HS conformance for /etc/init.d/pazpar2 PAZ-904
129 Debian: add support for /etc/init.d/pazpar2 status
131 --- 1.6.37 2013/11/18
133 Fix 'Record Missing' for command=show PAZ-903
135 Preserve order of records within cluster PAZ-902
137 testing: use yaz-ztest -V if possible and use YAZ in sibling directory
140 Allow clustered records to be ingested during retrieval. PAZ-900
142 Fix void function error which cannot return a value.
144 --- 1.6.36 2013/11/11
146 SRU pz:authentication="a/b" may end up as x-username=a%2Fb PAZ-899
148 Upgrade to debhelper version 7 PAZ-898
150 Package with libyaz5 PAZ-897
152 Better error message for CCL parse errors PAZ-887
154 --- 1.6.35 2013/09/23
156 New target setting: pz:authentication_mode. PAZ-896
158 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
160 Strip #-suffix for ZOOM URLs. PAZ-892
162 --- 1.6.34 2013/08/30
164 Fix issue with hanging show/bytarget. Could happen if new search was
165 fired with filter before show from previous show completed.
167 Add 'date' handling for solr-pz2.xsl.
169 --- 1.6.33 2013/08/13
171 pz:authentication may carry user group password. If pz:authentication
172 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
173 authentication. Two forms are allowed
176 If no blanks are present, open authentication is in use (as before).
178 Fix {prev,next}recid elements that are returned by record
179 command. These were incorrect in versions 1.6.23 thru 1.6.32.
181 --- 1.6.32 2013/06/14
183 Experimental support for snippets. If argument snippets=1 is given
184 for command record or show, the text will include <match>-tags for
185 those area that matches.
187 Fix memory leak WRT client structures (incorrect inc ref count).
189 Log when a HTTP response is serialized and the time elapsed.
191 New command, service, which returns current service XML in use for
194 --- 1.6.31 2013/05/24
196 Local limit for fields of type "generic" (ie text fields) are
197 now normalized by mergekey rule before comparison takes place.
198 Before, no normalization took place and comparsion was, thus, exact.
200 New facility: dynamic rank , which allows ranking to be changed
201 for an existing result set. The rank can be set for search or
202 show. This overrides the rank for metadata elements (which fields
205 New facility:dynamic mergekey , which allows mergekey to be changed
206 for an existing result set. The mergekey can be set for search or
209 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
210 Also, allow ports to be given as names (not just integers).
211 Fix @-notation on systems that don't support IPV6 sockets.
213 --- 1.6.30 2013/04/26
215 Add MasterKey Connect configuration. Refer to section "non-standard
216 databases" for more information.
218 Allow timeformat for log to be specified with option -m (as Metaproxy
221 New Debian package pazpar2-dbg.
223 Fix NULL ptr reference of se->relevance. If a new search is initiated
224 and a CCL query fails to parse, Pazpar2 could crash.
226 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
227 existed in 1.6.29 only.
229 --- 1.6.29 2013/04/05
231 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
232 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
233 changed by setting "host" attribute for the "listen" element.
235 Change semantics of pz:extendrecs. Allow for repeated fetches .
236 pz:extendrecs is now the number of extra records to fetch (was total
239 --- 1.6.28 2013/03/21
241 Fix hang or memory violation if show occurred before a search. (not that
242 it makes much sense to perform a show before a search).
244 --- 1.6.27 2013/03/08
246 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
249 --- 1.6.26 2013/03/08
251 New pz:metadata attribute, empty="empty-value" for Pazpar2's
252 internal representation. With this attribute, Pazpar2 treates an empty
253 pz:metadata type as having the value for "empty" - if empty.
255 New setting, pz:extendrecs, which triggers extended fetch of records
256 for a database beyond pz:maxrecs for a show command.
258 Fix warning that was falsely issued for "missing limitmap".
260 Log message for Pazpart start/stop changed. Now using same style as
261 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
263 --- 1.6.25 2013/02/07
265 Fix hang of 2nd command=show with esn/syntax given.
267 --- 1.6.24 2013/01/18
269 New merge attribute type: 'first', which takes all metadata fields
270 from first target that returns the particular field.
272 --- 1.6.23 2013/01/02
274 Extend info command with hostname and YAZ SHA1
275 Indent results for both command stat and info.
277 Allow limit on merged content. The new configuration metadata
278 element, limitcluster, configures that a metadata element (name) be used
279 as limit name for search. Applies to the whole service (ie all targets),
280 unlike pz:limitmap which is configured per-target (database).
282 New feature: limitmap local:* matches against all metadata fields.
284 Allow repeated list in limitmap spec . Separated by comma. For
285 example: value="local:title,rpn:@attr 1=4".
287 New element <message> in bytarget response. Holds diagnostic message
288 of code (say 'Unsupported Use Attribute' for Bib-1 114).
290 Improved logging for record ingestion failures.
292 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
293 when YAZ is compiled without ICU support.
295 --- 1.6.22 2012/10/11
297 Requires YAZ-4.2.40 to support native solr support.
299 Fix and improve logic handling whether or not to re-do search on sort
300 order changes. A sort order with change in ascending/descending only
301 whould not trigger a new search, which is required for targets with
302 native sorting capabilities. Each client is now checked if instructions
303 (sortmap) exist for native sorting and only client that does requires
304 it is researched. Other clients is just re-ingesting the records,
305 they already have. The resultset is now cleared if any researching
308 Connection sharing between session has broken since version 1.6.8 with
309 introduction of logic that would minimize searching if pazpar2 could
310 detect this based on same query and limits and partly sort order.
311 This could lead to segementations violations.
313 Added a chapter in the manaul about relevance ranking.
315 --- 1.6.21 2012/09/24
317 Rank tweak: follow=number will increase mult by number if two terms
318 occur next to each other; number-1 if they are one term apart , .. 0
319 if they are number a part (all in order). Default is 0 (following
320 terms has no effect).
322 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
323 value given by lead and l is length from beginning of field where
324 term occurs (l=0 for first term, l=1 for second term, ..). Default
327 Rank tweak: length=strategy. length="linear" if mult is to be divided
328 by length (existing, default behavior), length="log" if mult is to be
329 divided by log2(1+length), length="none" if mult is not to be affected
332 --- 1.6.20 2012/09/21
334 Rank algorithm details may be printed as part of show response in
335 element <relevance_info>.. This is only printed if <rank debug="yes"/>
338 Record as returned by show/record command have a minimal indentation
339 which makes things human-readable.
341 New configuration of default sorting criteria (sort-default) in
342 service definition. If no criteria is defined it will be as before
345 Search command now supports sort parameter just as the show command.
346 If no parameter is give, it will use the service sort-default value.
348 --- 1.6.19 2012/09/18
350 Rank algorithm skips strings that gets normalized to empty string.
351 For example, & and ! could map to the empty string. The weight for
352 those terms is now 0 (as if they were not part of the query).
354 Rank algorithm does not use CCL from limitmap; only from the query
355 parameter (user query).
359 --- 1.6.18 2012/09/17
361 Rank algorithm configurable by 'rank' element inside service. So far
362 only, attribute 'cluster' is recognized. If cluster="yes", multiple
363 records inside a cluster boosts higher than single records. This
364 is default behavior and existing behavior. cluster="no" takes the
365 average score of each record in a cluster.
367 --- 1.6.17 2012/09/05
369 Fix bad re-use of connections (connections with changing proxy should not
372 --- 1.6.16 2012/08/22
374 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
375 resultset and sorting when the sort order is position. However this will be done on
376 every client poll, which will make pazpar2 continuing reset and fetching.
377 It should only be done on FIRST request where the sort order change.
379 Fix an issue on suggestion option: Also disable suggestions on empty string.
381 Clean up in turbo marc stylesheet.
383 Remove the hardcoded size of termlists.
385 --- 1.6.15 2012/06/27
387 New facility: ccldirective may be given in service definition. Allows
388 CCL parsing to be customized a bit, such as defining names of operators
391 New facility: raw record by checksum, rather than offset. The record
392 command optionally takes checksum which identifies certain record from
395 New facility: per field ranking. Rank may be given as M [F N] where
396 M is default rank and N is rank for CCL terms from field F.
398 --- 1.6.14 2012/06/04
400 Fix for IE7/8 in pz.js
402 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
404 Lower log level some places.
406 Remove some invalid test results.
408 --- 1.6.13 2012/05/23
410 Introducing a version=2 parameter for show, termlist and bytarget commands.
411 This enables pazpar2 to return approximation on hit and count count when
412 doing record filtering using the limit parameter on search and a
413 limitmap with a value of "local:"
415 Setting pz:xslt may embed local XSLT as an alternative to referring
417 Value is not CDATA but XML nodes embedded, so escaping is not necessary
418 but a root element *must* be present. For example:
419 <settings target="target="z3950.indexdata.com/marc">
428 Metadata field rank may given by XML internal document (pz:xslt
429 result). If rank is not given, the rank from service description is
432 Metadata field can now configured a default limitmap and facetmap.
433 Setting limitmap to "local:" would work for all kind of targets, but would
434 prob. not be the optimal solution. But at least better than the default behavior
435 of pazpar2 where no filtering is done.
437 A service definition can now also contains <set/> that defines service-wide
438 settings. These will override server-wide sets and will be overridded by
441 New setting, pz:present_chunk, that specifies number of records to fetch
442 at a time. Zero will disable chunkation; will fetch max_records at once.
444 --- 1.6.12 2012/03/14
446 Revert the format change in termlist response, that could break
447 some clients / UIs since they were expecting an (empty) element
448 if no facet values was found.
450 --- 1.6.11 2012/03/07
452 Revert the behavior of returning errors when unable to block
453 on termlist, bytarget and search, when unable to block due to
454 other block. The client will now receive a regular response,
455 but it will be logged in the server. A parameter (report) is
456 added to change behavior to return error response or WARNING
457 status message. Consider this "API" as private, as it is mostly
458 untested and could be changed in future releases.
460 Fix spell error in pz2.js fix in 1.6.10.
462 New Marc2TurboMarc.xsl (contribution from Sven Porst).
463 Can solve the missing marc21.xsl updates in some cases.
465 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
466 substring (contribtion from Sven Porst)
468 marc21.xsl: fix 1-based substring call
470 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
472 Add test_termlist_block to test suite
474 --- 1.6.10 2012/02/23
476 Fix SEGV for invalid PQFs and SRU/SOLR targets
477 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
479 Fix pz2.js: "null object" due to change in in bytarget result XML.
481 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
482 Added this normalization to the other subject-long fields (d6xx),
483 where it was missing.
485 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
486 Still differences around medium and holdings. marc21.xsl is not
487 longer active used by Index Data, and should be considered unsupported.
488 Use tmarc.xsl instead.
492 Fix SEGV that could occur for failed connections.
496 Fix bug for command sort that could return no results for active clients
497 (from previous search). This bug was present in 1.6.6-1.6.7.
499 Fix bug in results that could include results that should have been
500 filtered out. This bug was present in 1.6.6-1.6.7.
504 Fix bug introduced in 1.6.6 where a connection re-use could stall
507 Local filtering may now specify a local metadata field, eg.
508 pz:limitmap:somefield[t]=local:otherfield
512 For search, when limit and or filtering is in place and search
513 is identical to previous search, the result set is re-used and the
514 target is not searched.
516 Limits may work perform local filtering as well, by using "local:"
521 Updated bytarget command to contain a suggestions element with misspelled
522 words and suggestions to these. pz2.js has been updated to deliver this
523 onwards as well. Only target that currently delivers this is the solr
524 client in YAZ 4.2.18.
528 New service definition element, xslt, that allows an embedded stylesheet
529 to be defined. This can be referred to from pz:xslt as an alternative to
532 New pz:sortmap:field setting for specifying hints on how to make
533 a target natively sort on a field. This is used for command=show in
534 conjunction with sort.
536 New pz:url setting for specifying the actual URL for a target. When
537 this is used the target ID is not used as URL anymore and the target ID
538 may be almost any string (not including []).
540 command=termlist without name parameter returns all termlists/facets.
541 Previously if name parameter was omitted, only "subject" was returned.
545 Make termlist sorting stable. Terms with same frequency are now sorted by
546 their display name. This makes a pretty display and improves our
547 regression test because qsort is not a stable sort.
549 New sort parameter value 'position'. The 'position' sorts merged records
550 by their original position from the remote target. This is primarily useful
551 for debugging and may be used for targets that already perform some kind
552 of relevance ranking. Note that sort by default is decreasing; so to get
553 records in their original order sort=position:1 must be used.
557 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
559 Facility to change working directory for pazpar2 daemon. Option -wdir
560 sets working directory to dir. This facility is useful if core dumps
561 must be saved. In this case, the current working directory must be
562 writable by the running user, such as "nobody".
566 New configuration element <icu_chain> for <server>/<service> which
567 allows a named ICU rule (chain) to be defined. The names relevance,
568 sort, mergekey and facet are used for those operations. The definition
569 <icu_chain id="sort" locale="en"> .. </icu_chain>
571 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
572 And so on.. for relevance, mergekey and facet as well. The latter
573 style is deprecated. The facet terms are normalized by the facet
574 rule by default. This may be changed on a metadata field basis by
575 defining the new attribute 'facetrule' for the metadata element.
577 <icu_chain id="myrule" locale="en"> ... </icu_chain>
578 <metadata name="author" termlist="yes" facetrule="myrule"/>
580 Preserve rorder for merged metadata. Fixes issue as reported by Sven
581 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
583 tmarc.xsl: set journal-subpart to 773$ only.
587 Modify the behavior for the limit parameter (first defined in 1.5.7).
588 Mapping of limit searches are now defined by the new configuration item
589 pz:limitmap. Fix a dead-lock problem with the limit parameter.
591 Extend tmarc.xsl to extract 773$g data (OpenURL).
595 ICU default maps remove backquote (`).
597 Command 'search' takes limit parameter (optional). The limit parameter
598 allows a search to be limited one or more facets and the corresponding
599 values. This is for server side filtering.
601 Configure tweak: Use -lm for log(3) if needed
605 Fix a problem with skiparticle sortkey that could be completely
606 ignored (and reduced to "").
608 Fix dependency problem in pazpar2 RPM package (did not require
609 libyaz4 as it should).
613 Fix memory leak that occurred for command=termlist&name=xtargets .
615 Pazpar2 may save HTTP requests. Enabled by option -R.
619 Experimental support for DTIC DADS target. New dads-pz2.xsl.
621 Support for query_syntax (overrides the default for SRU | Z39.50)
623 Support for extraArgs (ZOOM "extraArgs" option) for targets
625 New commands: status-server and status-session
629 Fix for threaded runs: Client now have a copy of the database URL,
630 which can used after the database has been release from the client.
631 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
633 tmarc.xsl: Add journal-title-abbrev and full text.
635 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
637 Fix for cmd=record before search.
639 Session Logging clean up.
641 Fix wrong termlist factor when maxrecs is different from 100.
645 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
646 Term factor is default enabled but can be diseabled by
647 pz:termlist_term_factor=0
651 Add scaling of facet count. Currently always enabled, needs fixing.
652 Allow user-defined info for target suffix. This has no meaning in
653 Pazpar2 except to distinguish targets from each other. The suffix
654 data begins with #. For example z3950.indexdata.com/gils#Mydata
656 Added exact-match recordfilter; format name=value
660 SOLR support. Pazpar2 may operate as web service client for SOLR.
664 Fix for show command and block=1 (dead lock). Bug was introduced in
669 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
670 tested on CentOS 5.5 only.
674 Fix problem with result sets being removed from a client session
675 if the connection for it was resused by another session. Bug #3489.
677 New iphone UI for Pazpar2 (www/iphone).
681 Fixes for threaded operation.
683 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
685 New example services in etc/services in source. In the Debian packages
686 these are located in /etc/pazpar2/services-available
688 Threaded mode operational on Windows. Requires Windows 7 or Windows
691 Default value of setting pz:max_connections is 0 which means that there
692 is no limit on number of connections.
696 Pazpar2 may operate in threaded mode. Enabled by element threads in
697 the configuration. See pazpar2_conf for details.
699 New setting setting: pz:max_connections. Setting pz:max_connections is
700 a limit of number of sockets to a host. When this limit is reached,
701 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
702 The client will be marked Client_Error when it can not be searched
703 (other clients in a session may work). If pz:max_connections is not set
704 for a target, a value of 30 will be used. Note: the pz:max_connections
705 will only work in threaded mode.
707 pz2.js: JSON support for show.
709 Debian package: Enable default service, default.xml, before starting
710 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
714 Debian version depends on on libyaz4. Note that Pazpar2 will still
715 compile from source with YAZ 3.
717 Split services into separate files. The example configuration file
718 pazpar2.cfg.dist now includes a default service default.xml (part of
719 etc). And default.xml includes settings/edu.xml. The default.xml file,
720 not to be confused with settings/defaults.xml, is a template for jsdemo
721 and other services. The Debian package installs /etc/pazpar2/server.xml
722 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
723 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
724 The default.xml (from etc) is installed in /etc/pazpar2/services-available
725 and a symlink to it is created from services-enabled. The default.xml
726 service is unnamed and, thus, will be used by jsdemo and test1.
728 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
729 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
733 Support for additional fields in cf.xsl and pazpar2.conf.dist:
734 publisher, available, due, location (=locallocation), callno
735 (=callnumber), thumburl and score.
737 Describe pz:xslt and the auto setting.
739 Move mergekey definition away from the normalization stylesheets and
740 define a mergekey common for all target types in pazpar2.cfg.
742 Code update: Use the Odr_int type for hit counts. This is part of
743 YAZ 3.0.47 and later and so configure checks for that.
747 Metadata attribute 'skiparticle' also works for ICU based
748 normalization. (was only working for the non-ICU/ASCII before).
750 Command bytarget with argument settings=1 will show settings per
751 target.. This is to be able to verify correct settings and be able to
752 test that they are correct. The database settings array size is now
753 also stored.. Problems with database settings array is that if not
754 careful it will be too small (smaller than dictionary per-service
757 Make record list sorting stable by comparing mergekey for records if
758 relevance/title or other sorting criteria all match. This is merely to
759 ensure that our regressions tests works (reproducible output).
761 Relevance calculation changes: use a different denominator (length) for
762 per-field relevance scoring.. Instead of length of all ranked fields we
763 now use length of individual fields (as if they were individual "free"
764 text fields). This will ensure that documents with a long field with no
765 match (say description) will not "hurt" a title match.
767 Diagnostic member was not set on connection error. Fixed
771 Command search takes two optional parameters, startecs and maxrecs,
772 that specifies the start offset (0, 1, ...) and maximum number of records
773 to fetch for each target.
775 XSLTs + MARC maps are cached within a session so we don't re-parse
776 them over and over again. Even for a session with a single search
777 there's much to be gained because many targets use the same
780 The metadata attribute 'mergekey' now takes one of three values 'no',
781 'required', 'optional' . And the resulting mergekey from metadata
782 is now ordered in the same way as metadata in the service definition.
783 Older Pazpar2 version use the order in which metadata appeared in a
786 The search argument 'filter' now offers a new operator ~ which does a
787 substring match. The = operator works as before: string match for
788 anything but pz:id, or target match for pz:id.
790 New setting pz:recordfilter. The value of this setting takes the
791 form name[~value]. This setting makes Pazpar2 ignore all retrieved
792 records that do not have the metadata element name with value substring
795 Pazpar2 allows YAZ log level to be set (option -v).
799 For WS responses Pazpar2 creates XML header. Exception: raw record.
801 Setting XML files are now stored in etc/settings instead of etc. This
802 reflects the layout with the Debian package layout.
804 Settings may be posted for command=settings. The POSTed settings must
805 have root element 'settings' like regular setting files. In order to be
806 recognized, the POST request must use Content-Type=text/xml.
808 A service may be posted for command=init. This service will be used
809 during the session. The service may have its own target settings,
810 ICU config, timeout, etc. In order to be recognized, the POST request
811 must use Content-Type=text/xml.
813 Timeout values may be given per-service. That's element 'timeout'
814 which takes three attribute values (a subset may be given): 'session',
815 'z3950_operation', 'z3950_session'. Option -T is no longer supported
816 - used to specify session timeout.
818 Option -t tests the Pazpar2 configuration and returns exit code
819 (0=success, non-zero=failure). In previous version of Pazpar2, -t
820 specified local settings.
822 In version 1.2.0 the configuration file - after include processing -
823 was dumped to stdout. Now, the configuration is only dumped to the
824 yaz log file if option -d is given.
828 Configuration may now have multiple server areas. This means that a
829 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
830 yet supported - on a server basis. Configuration may also have multiple
831 services .. That is repeating service elements inside a server. Each
832 has an attribute 'id' which serves as service ID. This ID in turn may
833 be used in a Pazpar2 session, by specifying parameter service=ID for
834 command init. There can be at most one unnamed service inside a server
835 which can be referred to by not specifying an service ID for command
836 init (backwards compatible). In order to partition multiple servers and
837 services a new include directive has been added. This takes an attribute
838 'src' which specifies one or more sub-files. For example to include
839 service files, one might use:
840 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
841 It is the intention that that completely makes the settings directive
844 Fix problem where the record command would wait forever if there were
845 no targets to wait for (activeclients == 0).
849 One result set is created per session (last search) rather than for
850 each connection which happen to be shared (bug #3009).
852 marc21 stylesheets changed for efficiency.
856 Session timeout may be specified on the command-line as option -T.
858 Pazpar2 may now be operated in a no-merged mode for records.. All records
859 will be considered unique. This mode is enabled if no mergekey is
860 generated by the normalization stylesheet (pz:xslt).
862 Pazpar2 caches original records from each target and the 'record' command
863 with offset returns the original record if 'syntax' and 'esn' are NOT
864 specified. This speeds up retrieval of original records but also means
865 that Pazpar2 uses more memory. The cached records will be freed when the
866 session terminates or a new search is executed.
868 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
869 library part of YAZ is used.
871 Added SRU client support.
873 Automatically computes pz:nativesyntax if not provided. Works for XML and
876 --- 1.0.13 2008/11/24
878 Command bytarget returns name of target (if defined).
880 --- 1.0.12 2008/11/04
882 Fixed bug #2021.. location now holds all brief elements.
884 --- 1.0.11 2008/10/15
886 Fixed check for application/x-www-form-urlencoded parameters.
888 --- 1.0.10 2008/10/14
890 Fixes for IE in pz2.js.
892 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
896 Changed the JS library pz2.js to use POST for long URL (+ params).
898 Added installation instructions for Windows. Note: NT services is
899 NOT available until we make a new release of YAZ.
901 Preserve order of repeated metadata fields (they were reversed before).
903 More MARC21 information extracted for metadata.
907 Fixed bug #1162: HTML entities are not escaped properly.
909 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
913 Marc21 stylesheet updated to reflect multiple full text fields
917 Fixed bug in pz2.js WRT DOMElement attributes on IE.
919 Fixed bug 2100: Database wildcards not working
923 Added support for retrieval of records in binary.
925 Fixed bug 1794: Pazpar2 does not return valid XML.
927 Deal with ICU not returning sortkey (resulted in SEGV before).
931 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
932 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
934 Improved diagnostics when Pazpar2 HTTP decoding fails.
936 Pazpar2 requests may be POSTed as using Content-Type
937 application/x-www-form-urlencoded.
939 Pazpar2 honors LF in HTTP headers.
941 Handle targets that handle negative hit counts (should not happen, but it
946 ICU is used for tokenization and normalization of the following: mergekey,
947 sorting, relevance terms.
949 Debian package now enables ICU tokenization and normalization by default.
953 Exposed user setting values (i.e. non-pz: names) to the record systems in two
954 ways: Either as parameters to the normalization stylesheets (which would allow the
955 programmer to postprocess or use the values in any way) or after the normalization
956 step, in which case values are made part of the normalized record (and available for
957 sorting, termlists, display, or other interface-related use.
959 Implemented sorting by year.
961 Option -d dumps records to the current log file instead of stderr.
963 Fixes for compilation on cygwin.
965 Z39.50 client code uses pz:elements. pz:elements was recognized in
966 earlier Pazpar2 versions but it was not used for anything.
968 icu_chain_test is using fgets instead of getline - fixes compilation
971 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
972 query conversions fail (rather than _any_). This means targets that do
973 not support some fields are ignored in a search.
977 Improved handling of socket timeout for Z39.50 connections.
979 Misc documentation updates and spell fixes.
981 Debian package pazpar2 creates log rotate entry.
983 Debian package pazpar2-apache2 reloads Apache2.
985 jsdemo included in distribution. It illustrates the use of the js/pz2.js
990 First public release.
