1 Fix SEGV that could occur for failed connections.
5 Fix bug for command sort that could return no results for active clients
6 (from previous search). This bug was present in 1.6.6-1.6.7.
8 Fix bug in results that could include results that should have been
9 filtered out. This bug was present in 1.6.6-1.6.7.
13 Fix bug introduced in 1.6.6 where a connection re-use could stall
16 Local filtering may now specify a local metadata field, eg.
17 pz:limitmap:somefield[t]=local:otherfield
21 For search, when limit and or filtering is in place and search
22 is identical to previous search, the result set is re-used and the
23 target is not searched.
25 Limits may work perform local filtering as well, by using "local:"
30 Updated bytarget command to contain a suggestions element with misspelled
31 words and suggestions to these. pz2.js has been updated to deliver this
32 onwards as well. Only target that currently delivers this is the solr
37 New service definition element, xslt, that allows an embedded stylesheet
38 to be defined. This can be referred to from pz:xslt as an alternative to
41 New pz:sortmap:field setting for specifying hints on how to make
42 a target natively sort on a field. This is used for command=show in
43 conjunction with sort.
45 New pz:url setting for specifying the actual URL for a target. When
46 this is used the target ID is not used as URL anymore and the target ID
47 may be almost any string (not including []).
49 command=termlist without name parameter returns all termlists/facets.
50 Previously if name parameter was omitted, only "subject" was returned.
54 Make termlist sorting stable. Terms with same frequency are now sorted by
55 their display name. This makes a pretty display and improves our
56 regression test because qsort is not a stable sort.
58 New sort parameter value 'position'. The 'position' sorts merged records
59 by their original position from the remote target. This is primarily useful
60 for debugging and may be used for targets that already perform some kind
61 of relevance ranking. Note that sort by default is decreasing; so to get
62 records in their original order sort=position:1 must be used.
66 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
68 Facility to change working directory for pazpar2 daemon. Option -wdir
69 sets working directory to dir. This facility is useful if core dumps
70 must be saved. In this case, the current working directory must be
71 writable by the running user, such as "nobody".
75 New configuration element <icu_chain> for <server>/<service> which
76 allows a named ICU rule (chain) to be defined. The names relevance,
77 sort, mergekey and facet are used for those operations. The definition
78 <icu_chain id="sort" locale="en"> .. </icu_chain>
80 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
81 And so on.. for relevance, mergekey and facet as well. The latter
82 style is deprecated. The facet terms are normalized by the facet
83 rule by default. This may be changed on a metadata field basis by
84 defining the new attribute 'facetrule' for the metadata element.
86 <icu_chain id="myrule" locale="en"> ... </icu_chain>
87 <metadata name="author" termlist="yes" facetrule="myrule"/>
89 Preserve rorder for merged metadata. Fixes issue as reported by Sven
90 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
92 tmarc.xsl: set journal-subpart to 773$ only.
96 Modify the behavior for the limit parameter (first defined in 1.5.7).
97 Mapping of limit searches are now defined by the new configuration item
98 pz:limitmap. Fix a dead-lock problem with the limit parameter.
100 Extend tmarc.xsl to extract 773$g data (OpenURL).
104 ICU default maps remove backquote (`).
106 Command 'search' takes limit parameter (optional). The limit parameter
107 allows a search to be limited one or more facets and the corresponding
108 values. This is for server side filtering.
110 Configure tweak: Use -lm for log(3) if needed
114 Fix a problem with skiparticle sortkey that could be completely
115 ignored (and reduced to "").
117 Fix dependency problem in pazpar2 RPM package (did not require
118 libyaz4 as it should).
122 Fix memory leak that occurred for command=termlist&name=xtargets .
124 Pazpar2 may save HTTP requests. Enabled by option -R.
128 Experimental support for DTIC DADS target. New dads-pz2.xsl.
130 Support for query_syntax (overrides the default for SRU | Z39.50)
132 Support for extraArgs (ZOOM "extraArgs" option) for targets
134 New commands: status-server and status-session
138 Fix for threaded runs: Client now have a copy of the database URL,
139 which can used after the database has been release from the client.
140 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
142 tmarc.xsl: Add journal-title-abbrev and full text.
144 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
146 Fix for cmd=record before search.
148 Session Logging clean up.
150 Fix wrong termlist factor when maxrecs is different from 100.
154 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
155 Term factor is default enabled but can be diseabled by
156 pz:termlist_term_factor=0
160 Add scaling of facet count. Currently always enabled, needs fixing.
161 Allow user-defined info for target suffix. This has no meaning in
162 Pazpar2 except to distinguish targets from each other. The suffix
163 data begins with #. For example z3950.indexdata.com/gils#Mydata
165 Added exact-match recordfilter; format name=value
169 SOLR support. Pazpar2 may operate as web service client for SOLR.
173 Fix for show command and block=1 (dead lock). Bug was introduced in
178 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
179 tested on CentOS 5.5 only.
183 Fix problem with result sets being removed from a client session
184 if the connection for it was resused by another session. Bug #3489.
186 New iphone UI for Pazpar2 (www/iphone).
190 Fixes for threaded operation.
192 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
194 New example services in etc/services in source. In the Debian packages
195 these are located in /etc/pazpar2/services-available
197 Threaded mode operational on Windows. Requires Windows 7 or Windows
200 Default value of setting pz:max_connections is 0 which means that there
201 is no limit on number of connections.
205 Pazpar2 may operate in threaded mode. Enabled by element threads in
206 the configuration. See pazpar2_conf for details.
208 New setting setting: pz:max_connections. Setting pz:max_connections is
209 a limit of number of sockets to a host. When this limit is reached,
210 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
211 The client will be marked Client_Error when it can not be searched
212 (other clients in a session may work). If pz:max_connections is not set
213 for a target, a value of 30 will be used. Note: the pz:max_connections
214 will only work in threaded mode.
216 pz2.js: JSON support for show.
218 Debian package: Enable default service, default.xml, before starting
219 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
223 Debian version depends on on libyaz4. Note that Pazpar2 will still
224 compile from source with YAZ 3.
226 Split services into separate files. The example configuration file
227 pazpar2.cfg.dist now includes a default service default.xml (part of
228 etc). And default.xml includes settings/edu.xml. The default.xml file,
229 not to be confused with settings/defaults.xml, is a template for jsdemo
230 and other services. The Debian package installs /etc/pazpar2/server.xml
231 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
232 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
233 The default.xml (from etc) is installed in /etc/pazpar2/services-available
234 and a symlink to it is created from services-enabled. The default.xml
235 service is unnamed and, thus, will be used by jsdemo and test1.
237 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
238 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
242 Support for additional fields in cf.xsl and pazpar2.conf.dist:
243 publisher, available, due, location (=locallocation), callno
244 (=callnumber), thumburl and score.
246 Describe pz:xslt and the auto setting.
248 Move mergekey definition away from the normalization stylesheets and
249 define a mergekey common for all target types in pazpar2.cfg.
251 Code update: Use the Odr_int type for hit counts. This is part of
252 YAZ 3.0.47 and later and so configure checks for that.
256 Metadata attribute 'skiparticle' also works for ICU based
257 normalization. (was only working for the non-ICU/ASCII before).
259 Command bytarget with argument settings=1 will show settings per
260 target.. This is to be able to verify correct settings and be able to
261 test that they are correct. The database settings array size is now
262 also stored.. Problems with database settings array is that if not
263 careful it will be too small (smaller than dictionary per-service
266 Make record list sorting stable by comparing mergekey for records if
267 relevance/title or other sorting criteria all match. This is merely to
268 ensure that our regressions tests works (reproducible output).
270 Relevance calculation changes: use a different denominator (length) for
271 per-field relevance scoring.. Instead of length of all ranked fields we
272 now use length of individual fields (as if they were individual "free"
273 text fields). This will ensure that documents with a long field with no
274 match (say description) will not "hurt" a title match.
276 Diagnostic member was not set on connection error. Fixed
280 Command search takes two optional parameters, startecs and maxrecs,
281 that specifies the start offset (0, 1, ...) and maximum number of records
282 to fetch for each target.
284 XSLTs + MARC maps are cached within a session so we don't re-parse
285 them over and over again. Even for a session with a single search
286 there's much to be gained because many targets use the same
289 The metadata attribute 'mergekey' now takes one of three values 'no',
290 'required', 'optional' . And the resulting mergekey from metadata
291 is now ordered in the same way as metadata in the service definition.
292 Older Pazpar2 version use the order in which metadata appeared in a
295 The search argument 'filter' now offers a new operator ~ which does a
296 substring match. The = operator works as before: string match for
297 anything but pz:id, or target match for pz:id.
299 New setting pz:recordfilter. The value of this setting takes the
300 form name[~value]. This setting makes Pazpar2 ignore all retrieved
301 records that do not have the metadata element name with value substring
304 Pazpar2 allows YAZ log level to be set (option -v).
308 For WS responses Pazpar2 creates XML header. Exception: raw record.
310 Setting XML files are now stored in etc/settings instead of etc. This
311 reflects the layout with the Debian package layout.
313 Settings may be posted for command=settings. The POSTed settings must
314 have root element 'settings' like regular setting files. In order to be
315 recognized, the POST request must use Content-Type=text/xml.
317 A service may be posted for command=init. This service will be used
318 during the session. The service may have its own target settings,
319 ICU config, timeout, etc. In order to be recognized, the POST request
320 must use Content-Type=text/xml.
322 Timeout values may be given per-service. That's element 'timeout'
323 which takes three attribute values (a subset may be given): 'session',
324 'z3950_operation', 'z3950_session'. Option -T is no longer supported
325 - used to specify session timeout.
327 Option -t tests the Pazpar2 configuration and returns exit code
328 (0=success, non-zero=failure). In previous version of Pazpar2, -t
329 specified local settings.
331 In version 1.2.0 the configuration file - after include processing -
332 was dumped to stdout. Now, the configuration is only dumped to the
333 yaz log file if option -d is given.
337 Configuration may now have multiple server areas. This means that a
338 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
339 yet supported - on a server basis. Configuration may also have multiple
340 services .. That is repeating service elements inside a server. Each
341 has an attribute 'id' which serves as service ID. This ID in turn may
342 be used in a Pazpar2 session, by specifying parameter service=ID for
343 command init. There can be at most one unnamed service inside a server
344 which can be referred to by not specifying an service ID for command
345 init (backwards compatible). In order to partition multiple servers and
346 services a new include directive has been added. This takes an attribute
347 'src' which specifies one or more sub-files. For example to include
348 service files, one might use:
349 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
350 It is the intention that that completely makes the settings directive
353 Fix problem where the record command would wait forever if there were
354 no targets to wait for (activeclients == 0).
358 One result set is created per session (last search) rather than for
359 each connection which happen to be shared (bug #3009).
361 marc21 stylesheets changed for efficiency.
365 Session timeout may be specified on the command-line as option -T.
367 Pazpar2 may now be operated in a no-merged mode for records.. All records
368 will be considered unique. This mode is enabled if no mergekey is
369 generated by the normalization stylesheet (pz:xslt).
371 Pazpar2 caches original records from each target and the 'record' command
372 with offset returns the original record if 'syntax' and 'esn' are NOT
373 specified. This speeds up retrieval of original records but also means
374 that Pazpar2 uses more memory. The cached records will be freed when the
375 session terminates or a new search is executed.
377 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
378 library part of YAZ is used.
380 Added SRU client support.
382 Automatically computes pz:nativesyntax if not provided. Works for XML and
385 --- 1.0.13 2008/11/24
387 Command bytarget returns name of target (if defined).
389 --- 1.0.12 2008/11/04
391 Fixed bug #2021.. location now holds all brief elements.
393 --- 1.0.11 2008/10/15
395 Fixed check for application/x-www-form-urlencoded parameters.
397 --- 1.0.10 2008/10/14
399 Fixes for IE in pz2.js.
401 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
405 Changed the JS library pz2.js to use POST for long URL (+ params).
407 Added installation instructions for Windows. Note: NT services is
408 NOT available until we make a new release of YAZ.
410 Preserve order of repeated metadata fields (they were reversed before).
412 More MARC21 information extracted for metadata.
416 Fixed bug #1162: HTML entities are not escaped properly.
418 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
422 Marc21 stylesheet updated to reflect multiple full text fields
426 Fixed bug in pz2.js WRT DOMElement attributes on IE.
428 Fixed bug 2100: Database wildcards not working
432 Added support for retrieval of records in binary.
434 Fixed bug 1794: Pazpar2 does not return valid XML.
436 Deal with ICU not returning sortkey (resulted in SEGV before).
440 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
441 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
443 Improved diagnostics when Pazpar2 HTTP decoding fails.
445 Pazpar2 requests may be POSTed as using Content-Type
446 application/x-www-form-urlencoded.
448 Pazpar2 honors LF in HTTP headers.
450 Handle targets that handle negative hit counts (should not happen, but it
455 ICU is used for tokenization and normalization of the following: mergekey,
456 sorting, relevance terms.
458 Debian package now enables ICU tokenization and normalization by default.
462 Exposed user setting values (i.e. non-pz: names) to the record systems in two
463 ways: Either as parameters to the normalization stylesheets (which would allow the
464 programmer to postprocess or use the values in any way) or after the normalization
465 step, in which case values are made part of the normalized record (and available for
466 sorting, termlists, display, or other interface-related use.
468 Implemented sorting by year.
470 Option -d dumps records to the current log file instead of stderr.
472 Fixes for compilation on cygwin.
474 Z39.50 client code uses pz:elements. pz:elements was recognized in
475 earlier Pazpar2 versions but it was not used for anything.
477 icu_chain_test is using fgets instead of getline - fixes compilation
480 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
481 query conversions fail (rather than _any_). This means targets that do
482 not support some fields are ignored in a search.
486 Improved handling of socket timeout for Z39.50 connections.
488 Misc documentation updates and spell fixes.
490 Debian package pazpar2 creates log rotate entry.
492 Debian package pazpar2-apache2 reloads Apache2.
494 jsdemo included in distribution. It illustrates the use of the js/pz2.js
499 First public release.
