3 ICU default maps remove backquote (`).
5 Command 'search' takes limit parameter (optional). The limit parameter
6 allows a search to be limited one or more facets and the corresponding
7 values. This is for server side filtering.
9 Configure tweak: Use -lm for log(3) if needed
13 Fix a problem with skiparticle sortkey that could be completely
14 ignored (and reduced to "").
16 Fix dependency problem in pazpar2 RPM package (did not require
17 libyaz4 as it should).
21 Fix memory leak that occurred for command=termlist&name=xtargets .
23 Pazpar2 may save HTTP requests. Enabled by option -R.
27 Experimental support for DTIC DADS target. New dads-pz2.xsl.
29 Support for query_syntax (overrides the default for SRU | Z39.50)
31 Support for extraArgs (ZOOM "extraArgs" option) for targets
33 New commands: status-server and status-session
37 Fix for threaded runs: Client now have a copy of the database URL,
38 which can used after the database has been release from the client.
39 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
41 tmarc.xsl: Add journal-title-abbrev and full text.
43 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
45 Fix for cmd=record before search.
47 Session Logging clean up.
49 Fix wrong termlist factor when maxrecs is different from 100.
53 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
54 Term factor is default enabled but can be diseabled by
55 pz:termlist_term_factor=0
59 Add scaling of facet count. Currently always enabled, needs fixing.
60 Allow user-defined info for target suffix. This has no meaning in
61 Pazpar2 except to distinguish targets from each other. The suffix
62 data begins with #. For example z3950.indexdata.com/gils#Mydata
64 Added exact-match recordfilter; format name=value
68 SOLR support. Pazpar2 may operate as web service client for SOLR.
72 Fix for show command and block=1 (dead lock). Bug was introduced in
77 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
78 tested on CentOS 5.5 only.
82 Fix problem with result sets being removed from a client session
83 if the connection for it was resused by another session. Bug #3489.
85 New iphone UI for Pazpar2 (www/iphone).
89 Fixes for threaded operation.
91 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
93 New example services in etc/services in source. In the Debian packages
94 these are located in /etc/pazpar2/services-available
96 Threaded mode operational on Windows. Requires Windows 7 or Windows
99 Default value of setting pz:max_connections is 0 which means that there
100 is no limit on number of connections.
104 Pazpar2 may operate in threaded mode. Enabled by element threads in
105 the configuration. See pazpar2_conf for details.
107 New setting setting: pz:max_connections. Setting pz:max_connections is
108 a limit of number of sockets to a host. When this limit is reached,
109 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
110 The client will be marked Client_Error when it can not be searched
111 (other clients in a session may work). If pz:max_connections is not set
112 for a target, a value of 30 will be used. Note: the pz:max_connections
113 will only work in threaded mode.
115 pz2.js: JSON support for show.
117 Debian package: Enable default service, default.xml, before starting
118 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
122 Debian version depends on on libyaz4. Note that Pazpar2 will still
123 compile from source with YAZ 3.
125 Split services into separate files. The example configuration file
126 pazpar2.cfg.dist now includes a default service default.xml (part of
127 etc). And default.xml includes settings/edu.xml. The default.xml file,
128 not to be confused with settings/defaults.xml, is a template for jsdemo
129 and other services. The Debian package installs /etc/pazpar2/server.xml
130 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
131 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
132 The default.xml (from etc) is installed in /etc/pazpar2/services-available
133 and a symlink to it is created from services-enabled. The default.xml
134 service is unnamed and, thus, will be used by jsdemo and test1.
136 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
137 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
141 Support for additional fields in cf.xsl and pazpar2.conf.dist:
142 publisher, available, due, location (=locallocation), callno
143 (=callnumber), thumburl and score.
145 Describe pz:xslt and the auto setting.
147 Move mergekey definition away from the normalization stylesheets and
148 define a mergekey common for all target types in pazpar2.cfg.
150 Code update: Use the Odr_int type for hit counts. This is part of
151 YAZ 3.0.47 and later and so configure checks for that.
155 Metadata attribute 'skiparticle' also works for ICU based
156 normalization. (was only working for the non-ICU/ASCII before).
158 Command bytarget with argument settings=1 will show settings per
159 target.. This is to be able to verify correct settings and be able to
160 test that they are correct. The database settings array size is now
161 also stored.. Problems with database settings array is that if not
162 careful it will be too small (smaller than dictionary per-service
165 Make record list sorting stable by comparing mergekey for records if
166 relevance/title or other sorting criteria all match. This is merely to
167 ensure that our regressions tests works (reproducible output).
169 Relevance calculation changes: use a different denominator (length) for
170 per-field relevance scoring.. Instead of length of all ranked fields we
171 now use length of individual fields (as if they were individual "free"
172 text fields). This will ensure that documents with a long field with no
173 match (say description) will not "hurt" a title match.
175 Diagnostic member was not set on connection error. Fixed
179 Command search takes two optional parameters, startecs and maxrecs,
180 that specifies the start offset (0, 1, ...) and maximum number of records
181 to fetch for each target.
183 XSLTs + MARC maps are cached within a session so we don't re-parse
184 them over and over again. Even for a session with a single search
185 there's much to be gained because many targets use the same
188 The metadata attribute 'mergekey' now takes one of three values 'no',
189 'required', 'optional' . And the resulting mergekey from metadata
190 is now ordered in the same way as metadata in the service definition.
191 Older Pazpar2 version use the order in which metadata appeared in a
194 The search argument 'filter' now offers a new operator ~ which does a
195 substring match. The = operator works as before: string match for
196 anything but pz:id, or target match for pz:id.
198 New setting pz:recordfilter. The value of this setting takes the
199 form name[~value]. This setting makes Pazpar2 ignore all retrieved
200 records that do not have the metadata element name with value substring
203 Pazpar2 allows YAZ log level to be set (option -v).
207 For WS responses Pazpar2 creates XML header. Exception: raw record.
209 Setting XML files are now stored in etc/settings instead of etc. This
210 reflects the layout with the Debian package layout.
212 Settings may be posted for command=settings. The POSTed settings must
213 have root element 'settings' like regular setting files. In order to be
214 recognized, the POST request must use Content-Type=text/xml.
216 A service may be posted for command=init. This service will be used
217 during the session. The service may have its own target settings,
218 ICU config, timeout, etc. In order to be recognized, the POST request
219 must use Content-Type=text/xml.
221 Timeout values may be given per-service. That's element 'timeout'
222 which takes three attribute values (a subset may be given): 'session',
223 'z3950_operation', 'z3950_session'. Option -T is no longer supported
224 - used to specify session timeout.
226 Option -t tests the Pazpar2 configuration and returns exit code
227 (0=success, non-zero=failure). In previous version of Pazpar2, -t
228 specified local settings.
230 In version 1.2.0 the configuration file - after include processing -
231 was dumped to stdout. Now, the configuration is only dumped to the
232 yaz log file if option -d is given.
236 Configuration may now have multiple server areas. This means that a
237 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
238 yet supported - on a server basis. Configuration may also have multiple
239 services .. That is repeating service elements inside a server. Each
240 has an attribute 'id' which serves as service ID. This ID in turn may
241 be used in a Pazpar2 session, by specifying parameter service=ID for
242 command init. There can be at most one unnamed service inside a server
243 which can be referred to by not specifying an service ID for command
244 init (backwards compatible). In order to partition multiple servers and
245 services a new include directive has been added. This takes an attribute
246 'src' which specifies one or more sub-files. For example to include
247 service files, one might use:
248 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
249 It is the intention that that completely makes the settings directive
252 Fix problem where the record command would wait forever if there were
253 no targets to wait for (activeclients == 0).
257 One result set is created per session (last search) rather than for
258 each connection which happen to be shared (bug #3009).
260 marc21 stylesheets changed for efficiency.
264 Session timeout may be specified on the command-line as option -T.
266 Pazpar2 may now be operated in a no-merged mode for records.. All records
267 will be considered unique. This mode is enabled if no mergekey is
268 generated by the normalization stylesheet (pz:xslt).
270 Pazpar2 caches original records from each target and the 'record' command
271 with offset returns the original record if 'syntax' and 'esn' are NOT
272 specified. This speeds up retrieval of original records but also means
273 that Pazpar2 uses more memory. The cached records will be freed when the
274 session terminates or a new search is executed.
276 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
277 library part of YAZ is used.
279 Added SRU client support.
281 Automatically computes pz:nativesyntax if not provided. Works for XML and
284 --- 1.0.13 2008/11/24
286 Command bytarget returns name of target (if defined).
288 --- 1.0.12 2008/11/04
290 Fixed bug #2021.. location now holds all brief elements.
292 --- 1.0.11 2008/10/15
294 Fixed check for application/x-www-form-urlencoded parameters.
296 --- 1.0.10 2008/10/14
298 Fixes for IE in pz2.js.
300 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
304 Changed the JS library pz2.js to use POST for long URL (+ params).
306 Added installation instructions for Windows. Note: NT services is
307 NOT available until we make a new release of YAZ.
309 Preserve order of repeated metadata fields (they were reversed before).
311 More MARC21 information extracted for metadata.
315 Fixed bug #1162: HTML entities are not escaped properly.
317 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
321 Marc21 stylesheet updated to reflect multiple full text fields
325 Fixed bug in pz2.js WRT DOMElement attributes on IE.
327 Fixed bug 2100: Database wildcards not working
331 Added support for retrieval of records in binary.
333 Fixed bug 1794: Pazpar2 does not return valid XML.
335 Deal with ICU not returning sortkey (resulted in SEGV before).
339 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
340 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
342 Improved diagnostics when Pazpar2 HTTP decoding fails.
344 Pazpar2 requests may be POSTed as using Content-Type
345 application/x-www-form-urlencoded.
347 Pazpar2 honors LF in HTTP headers.
349 Handle targets that handle negative hit counts (should not happen, but it
354 ICU is used for tokenization and normalization of the following: mergekey,
355 sorting, relevance terms.
357 Debian package now enables ICU tokenization and normalization by default.
361 Exposed user setting values (i.e. non-pz: names) to the record systems in two
362 ways: Either as parameters to the normalization stylesheets (which would allow the
363 programmer to postprocess or use the values in any way) or after the normalization
364 step, in which case values are made part of the normalized record (and available for
365 sorting, termlists, display, or other interface-related use.
367 Implemented sorting by year.
369 Option -d dumps records to the current log file instead of stderr.
371 Fixes for compilation on cygwin.
373 Z39.50 client code uses pz:elements. pz:elements was recognized in
374 earlier Pazpar2 versions but it was not used for anything.
376 icu_chain_test is using fgets instead of getline - fixes compilation
379 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
380 query conversions fail (rather than _any_). This means targets that do
381 not support some fields are ignored in a search.
385 Improved handling of socket timeout for Z39.50 connections.
387 Misc documentation updates and spell fixes.
389 Debian package pazpar2 creates log rotate entry.
391 Debian package pazpar2-apache2 reloads Apache2.
393 jsdemo included in distribution. It illustrates the use of the js/pz2.js
398 First public release.
