3 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
4 tested on CentOS 5.5 only.
8 Fix problem with result sets being removed from a client session
9 if the connection for it was resused by another session. Bug #3489.
11 New iphone UI for Pazpar2 (www/iphone).
15 Fixes for threaded operation.
17 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
19 New example services in etc/services in source. In the Debian packages
20 these are located in /etc/pazpar2/services-available
22 Threaded mode operational on Windows. Requires Windows 7 or Windows
25 Default value of setting pz:max_connections is 0 which means that there
26 is no limit on number of connections.
30 Pazpar2 may operate in threaded mode. Enabled by element threads in
31 the configuration. See pazpar2_conf for details.
33 New setting setting: pz:max_connections. Setting pz:max_connections is
34 a limit of number of sockets to a host. When this limit is reached,
35 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
36 The client will be marked Client_Error when it can not be searched
37 (other clients in a session may work). If pz:max_connections is not set
38 for a target, a value of 30 will be used. Note: the pz:max_connections
39 will only work in threaded mode.
41 pz2.js: JSON support for show.
43 Debian package: Enable default service, default.xml, before starting
44 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
48 Debian version depends on on libyaz4. Note that Pazpar2 will still
49 compile from source with YAZ 3.
51 Split services into separate files. The example configuration file
52 pazpar2.cfg.dist now includes a default service default.xml (part of
53 etc). And default.xml includes settings/edu.xml. The default.xml file,
54 not to be confused with settings/defaults.xml, is a template for jsdemo
55 and other services. The Debian package installs /etc/pazpar2/server.xml
56 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
57 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
58 The default.xml (from etc) is installed in /etc/pazpar2/services-available
59 and a symlink to it is created from services-enabled. The default.xml
60 service is unnamed and, thus, will be used by jsdemo and test1.
62 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
63 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
67 Support for additional fields in cf.xsl and pazpar2.conf.dist:
68 publisher, available, due, location (=locallocation), callno
69 (=callnumber), thumburl and score.
71 Describe pz:xslt and the auto setting.
73 Move mergekey definition away from the normalization stylesheets and
74 define a mergekey common for all target types in pazpar2.cfg.
76 Code update: Use the Odr_int type for hit counts. This is part of
77 YAZ 3.0.47 and later and so configure checks for that.
81 Metadata attribute 'skiparticle' also works for ICU based
82 normalization. (was only working for the non-ICU/ASCII before).
84 Command bytarget with argument settings=1 will show settings per
85 target.. This is to be able to verify correct settings and be able to
86 test that they are correct. The database settings array size is now
87 also stored.. Problems with database settings array is that if not
88 careful it will be too small (smaller than dictionary per-service
91 Make record list sorting stable by comparing mergekey for records if
92 relevance/title or other sorting criteria all match. This is merely to
93 ensure that our regressions tests works (reproducible output).
95 Relevance calculation changes: use a different denominator (length) for
96 per-field relevance scoring.. Instead of length of all ranked fields we
97 now use length of individual fields (as if they were individual "free"
98 text fields). This will ensure that documents with a long field with no
99 match (say description) will not "hurt" a title match.
101 Diagnostic member was not set on connection error. Fixed
105 Command search takes two optional parameters, startecs and maxrecs,
106 that specifies the start offset (0, 1, ...) and maximum number of records
107 to fetch for each target.
109 XSLTs + MARC maps are cached within a session so we don't re-parse
110 them over and over again. Even for a session with a single search
111 there's much to be gained because many targets use the same
114 The metadata attribute 'mergekey' now takes one of three values 'no',
115 'required', 'optional' . And the resulting mergekey from metadata
116 is now ordered in the same way as metadata in the service definition.
117 Older Pazpar2 version use the order in which metadata appeared in a
120 The search argument 'filter' now offers a new operator ~ which does a
121 substring match. The = operator works as before: string match for
122 anything but pz:id, or target match for pz:id.
124 New setting pz:recordfilter. The value of this setting takes the
125 form name[~value]. This setting makes Pazpar2 ignore all retrieved
126 records that do not have the metadata element name with value substring
129 Pazpar2 allows YAZ log level to be set (option -v).
133 For WS responses Pazpar2 creates XML header. Exception: raw record.
135 Setting XML files are now stored in etc/settings instead of etc. This
136 reflects the layout with the Debian package layout.
138 Settings may be posted for command=settings. The POSTed settings must
139 have root element 'settings' like regular setting files. In order to be
140 recognized, the POST request must use Content-Type=text/xml.
142 A service may be posted for command=init. This service will be used
143 during the session. The service may have its own target settings,
144 ICU config, timeout, etc. In order to be recognized, the POST request
145 must use Content-Type=text/xml.
147 Timeout values may be given per-service. That's element 'timeout'
148 which takes three attribute values (a subset may be given): 'session',
149 'z3950_operation', 'z3950_session'. Option -T is no longer supported
150 - used to specify session timeout.
152 Option -t tests the Pazpar2 configuration and returns exit code
153 (0=success, non-zero=failure). In previous version of Pazpar2, -t
154 specified local settings.
156 In version 1.2.0 the configuration file - after include processing -
157 was dumped to stdout. Now, the configuration is only dumped to the
158 yaz log file if option -d is given.
162 Configuration may now have multiple server areas. This means that a
163 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
164 yet supported - on a server basis. Configuration may also have multiple
165 services .. That is repeating service elements inside a server. Each
166 has an attribute 'id' which serves as service ID. This ID in turn may
167 be used in a Pazpar2 session, by specifying parameter service=ID for
168 command init. There can be at most one unnamed service inside a server
169 which can be referred to by not specifying an service ID for command
170 init (backwards compatible). In order to partition multiple servers and
171 services a new include directive has been added. This takes an attribute
172 'src' which specifies one or more sub-files. For example to include
173 service files, one might use:
174 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
175 It is the intention that that completely makes the settings directive
178 Fix problem where the record command would wait forever if there were
179 no targets to wait for (activeclients == 0).
183 One result set is created per session (last search) rather than for
184 each connection which happen to be shared (bug #3009).
186 marc21 stylesheets changed for efficiency.
190 Session timeout may be specified on the command-line as option -T.
192 Pazpar2 may now be operated in a no-merged mode for records.. All records
193 will be considered unique. This mode is enabled if no mergekey is
194 generated by the normalization stylesheet (pz:xslt).
196 Pazpar2 caches original records from each target and the 'record' command
197 with offset returns the original record if 'syntax' and 'esn' are NOT
198 specified. This speeds up retrieval of original records but also means
199 that Pazpar2 uses more memory. The cached records will be freed when the
200 session terminates or a new search is executed.
202 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
203 library part of YAZ is used.
205 Added SRU client support.
207 Automatically computes pz:nativesyntax if not provided. Works for XML and
210 --- 1.0.13 2008/11/24
212 Command bytarget returns name of target (if defined).
214 --- 1.0.12 2008/11/04
216 Fixed bug #2021.. location now holds all brief elements.
218 --- 1.0.11 2008/10/15
220 Fixed check for application/x-www-form-urlencoded parameters.
222 --- 1.0.10 2008/10/14
224 Fixes for IE in pz2.js.
226 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
230 Changed the JS library pz2.js to use POST for long URL (+ params).
232 Added installation instructions for Windows. Note: NT services is
233 NOT available until we make a new release of YAZ.
235 Preserve order of repeated metadata fields (they were reversed before).
237 More MARC21 information extracted for metadata.
241 Fixed bug #1162: HTML entities are not escaped properly.
243 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
247 Marc21 stylesheet updated to reflect multiple full text fields
251 Fixed bug in pz2.js WRT DOMElement attributes on IE.
253 Fixed bug 2100: Database wildcards not working
257 Added support for retrieval of records in binary.
259 Fixed bug 1794: Pazpar2 does not return valid XML.
261 Deal with ICU not returning sortkey (resulted in SEGV before).
265 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
266 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
268 Improved diagnostics when Pazpar2 HTTP decoding fails.
270 Pazpar2 requests may be POSTed as using Content-Type
271 application/x-www-form-urlencoded.
273 Pazpar2 honors LF in HTTP headers.
275 Handle targets that handle negative hit counts (should not happen, but it
280 ICU is used for tokenization and normalization of the following: mergekey,
281 sorting, relevance terms.
283 Debian package now enables ICU tokenization and normalization by default.
287 Exposed user setting values (i.e. non-pz: names) to the record systems in two
288 ways: Either as parameters to the normalization stylesheets (which would allow the
289 programmer to postprocess or use the values in any way) or after the normalization
290 step, in which case values are made part of the normalized record (and available for
291 sorting, termlists, display, or other interface-related use.
293 Implemented sorting by year.
295 Option -d dumps records to the current log file instead of stderr.
297 Fixes for compilation on cygwin.
299 Z39.50 client code uses pz:elements. pz:elements was recognized in
300 earlier Pazpar2 versions but it was not used for anything.
302 icu_chain_test is using fgets instead of getline - fixes compilation
305 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
306 query conversions fail (rather than _any_). This means targets that do
307 not support some fields are ignored in a search.
311 Improved handling of socket timeout for Z39.50 connections.
313 Misc documentation updates and spell fixes.
315 Debian package pazpar2 creates log rotate entry.
317 Debian package pazpar2-apache2 reloads Apache2.
319 jsdemo included in distribution. It illustrates the use of the js/pz2.js
324 First public release.
