3 Metadata attribute 'skiparticle' also works for ICU based
4 normalization. (was only working for the non-ICU/ASCII before).
6 Command bytarget with argument settings=1 will show settings per
7 target.. This is to be able to verify correct settings and be able to
8 test that they are correct. The database settings array size is now
9 also stored.. Problems with database settings array is that if not
10 careful it will be too small (smaller than dictionary per-service
13 Make record list sorting stable by comparing mergekey for records if
14 relevance/title or other sorting criteria all match. This is merely to
15 ensure that our regressions tests works (reproducible output).
17 Relevance calculation changes: use a different denominator (length) for
18 per-field relevance scoring.. Instead of length of all ranked fields we
19 now use length of individual fields (as if they were individual "free"
20 text fields). This will ensure that documents with a long field with no
21 match (say description) will not "hurt" a title match.
23 Diagnostic member was not set on connection error. Fixed
27 Command search takes two optional parameters, startecs and maxrecs,
28 that specifies the start offset (0, 1, ...) and maximum number of records
29 to fetch for each target.
31 XSLTs + MARC maps are cached within a session so we don't re-parse
32 them over and over again. Even for a session with a single search
33 there's much to be gained because many targets use the same
36 The metadata attribute 'mergekey' now takes one of three values 'no',
37 'required', 'optional' . And the resulting mergekey from metadata
38 is now ordered in the same way as metadata in the service definition.
39 Older Pazpar2 version use the order in which metadata appeared in a
42 The search argument 'filter' now offers a new operator ~ which does a
43 substring match. The = operator works as before: string match for
44 anything but pz:id, or target match for pz:id.
46 New setting pz:recordfilter. The value of this setting takes the
47 form name[~value]. This setting makes Pazpar2 ignore all retrieved
48 records that do not have the metadata element name with value substring
51 Pazpar2 allows YAZ log level to be set (option -v).
55 For WS responses Pazpar2 creates XML header. Exception: raw record.
57 Setting XML files are now stored in etc/settings instead of etc. This
58 reflects the layout with the Debian package layout.
60 Settings may be posted for command=settings. The POSTed settings must
61 have root element 'settings' like regular setting files. In order to be
62 recognized, the POST request must use Content-Type=text/xml.
64 A service may be posted for command=init. This service will be used
65 during the session. The service may have its own target settings,
66 ICU config, timeout, etc. In order to be recognized, the POST request
67 must use Content-Type=text/xml.
69 Timeout values may be given per-service. That's element 'timeout'
70 which takes three attribute values (a subset may be given): 'session',
71 'z3950_operation', 'z3950_session'. Option -T is no longer supported
72 - used to specify session timeout.
74 Option -t tests the Pazpar2 configuration and returns exit code
75 (0=success, non-zero=failure). In previous version of Pazpar2, -t
76 specified local settings.
78 In version 1.2.0 the configuration file - after include processing -
79 was dumped to stdout. Now, the configuration is only dumped to the
80 yaz log file if option -d is given.
84 Configuration may now have multiple server areas. This means that a
85 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
86 yet supported - on a server basis. Configuration may also have multiple
87 services .. That is repeating service elements inside a server. Each
88 has an attribute 'id' which serves as service ID. This ID in turn may
89 be used in a Pazpar2 session, by specifying parameter service=ID for
90 command init. There can be at most one unnamed service inside a server
91 which can be referred to by not specifying an service ID for command
92 init (backwards compatible). In order to partition multiple servers and
93 services a new include directive has been added. This takes an attribute
94 'src' which specifies one or more sub-files. For example to include
95 service files, one might use:
96 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
97 It is the intention that that completely makes the settings directive
100 Fix problem where the record command would wait forever if there were
101 no targets to wait for (activeclients == 0).
105 One result set is created per session (last search) rather than for
106 each connection which happen to be shared (bug #3009).
108 marc21 stylesheets changed for efficiency.
112 Session timeout may be specified on the command-line as option -T.
114 Pazpar2 may now be operated in a no-merged mode for records.. All records
115 will be considered unique. This mode is enabled if no mergekey is
116 generated by the normalization stylesheet (pz:xslt).
118 Pazpar2 caches original records from each target and the 'record' command
119 with offset returns the original record if 'syntax' and 'esn' are NOT
120 specified. This speeds up retrieval of original records but also means
121 that Pazpar2 uses more memory. The cached records will be freed when the
122 session terminates or a new search is executed.
124 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
125 library part of YAZ is used.
127 Added SRU client support.
129 Automatically computes pz:nativesyntax if not provided. Works for XML and
132 --- 1.0.13 2008/11/24
134 Command bytarget returns name of target (if defined).
136 --- 1.0.12 2008/11/04
138 Fixed bug #2021.. location now holds all brief elements.
140 --- 1.0.11 2008/10/15
142 Fixed check for application/x-www-form-urlencoded parameters.
144 --- 1.0.10 2008/10/14
146 Fixes for IE in pz2.js.
148 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
152 Changed the JS library pz2.js to use POST for long URL (+ params).
154 Added installation instructions for Windows. Note: NT services is
155 NOT available until we make a new release of YAZ.
157 Preserve order of repeated metadata fields (they were reversed before).
159 More MARC21 information extracted for metadata.
163 Fixed bug #1162: HTML entities are not escaped properly.
165 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
169 Marc21 stylesheet updated to reflect multiple full text fields
173 Fixed bug in pz2.js WRT DOMElement attributes on IE.
175 Fixed bug 2100: Database wildcards not working
179 Added support for retrieval of records in binary.
181 Fixed bug 1794: Pazpar2 does not return valid XML.
183 Deal with ICU not returning sortkey (resulted in SEGV before).
187 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
188 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
190 Improved diagnostics when Pazpar2 HTTP decoding fails.
192 Pazpar2 requests may be POSTed as using Content-Type
193 application/x-www-form-urlencoded.
195 Pazpar2 honors LF in HTTP headers.
197 Handle targets that handle negative hit counts (should not happen, but it
202 ICU is used for tokenization and normalization of the following: mergekey,
203 sorting, relevance terms.
205 Debian package now enables ICU tokenization and normalization by default.
209 Exposed user setting values (i.e. non-pz: names) to the record systems in two
210 ways: Either as parameters to the normalization stylesheets (which would allow the
211 programmer to postprocess or use the values in any way) or after the normalization
212 step, in which case values are made part of the normalized record (and available for
213 sorting, termlists, display, or other interface-related use.
215 Implemented sorting by year.
217 Option -d dumps records to the current log file instead of stderr.
219 Fixes for compilation on cygwin.
221 Z39.50 client code uses pz:elements. pz:elements was recognized in
222 earlier Pazpar2 versions but it was not used for anything.
224 icu_chain_test is using fgets instead of getline - fixes compilation
227 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
228 query conversions fail (rather than _any_). This means targets that do
229 not support some fields are ignored in a search.
233 Improved handling of socket timeout for Z39.50 connections.
235 Misc documentation updates and spell fixes.
237 Debian package pazpar2 creates log rotate entry.
239 Debian package pazpar2-apache2 reloads Apache2.
241 jsdemo included in distribution. It illustrates the use of the js/pz2.js
