3 zoom: new target profile setting: sortmap_field. If sortmap_field is given
4 the field is mapped to the value for the sortmap. Values not matching
5 sortmap_field are passed verbatim.
7 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
8 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
9 depending on whether RPN or CQL is actually sent to the target.
13 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
15 zoom: For content proxy authentication is stored in param name
16 "auth", instead of "authentication".
20 zoom: relay schema in SRU mode. Previously recordSchema was not affected
25 zoom: new target profile element literalTransform that holds XSLT
26 (encoded as string) for target. Only if present and non-zero length it is
27 considered present. This takes precedence over transform.
29 Don't rely on trang anymore for Git checkout builds. Configuration in etc
30 will only be properly validated if trang is available. From now on only
31 relax NC files are bundled with the source dist.
33 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
34 component was not detected when it should be.
38 z3950_client: mark non-surrogate diagnostics from backend.
40 zoom: a proxy may be specified for HTTP fetch of target profiles.
44 Honor piggyback. Makes some SRU targets behave that insist on
45 maximumRecords > 0, but also increases performance.
49 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
50 file was not update for libdir/metaproxy4 in version 1.3.2.
54 Change location of Metaproxy modules from libdir/metaproxy to
55 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
56 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
58 New facility to dump APDUs from zoom filter. Enabled by
59 <log apdu="true"/> in the zoom filter configuation.
61 zoom filter bug fix: SRU diagnostics received from backend was
62 not properly converted to Bib-1 diagnostics.
64 Package metaproxy depends on libmetaproxy4, same version.
68 zoom: fix a bug WRT passing authentication parameters to backends.
72 Fixes for windows Makefile.
76 Change major version of metaproxy library from 3 to 4. This in turn
77 makes new package names for Debian and RPM.
81 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
84 zoom: configurable element sets for record transforms.
86 zoom: the target profile based transform is specified by element_transform
87 in element torus of of the ZOOM filter configuration ; default value
88 is "pz2". Target profile based retrieval is specified by element_raw
89 in configuration. It will perform same steps, but omit the XSL transform.
90 Default value is "raw".
92 zoom: element set is omitted if not set in profile. But only if pz2
93 transform is in effect. Previously the default element set was to "F".
95 zoom: For non-CF targets database arguments are parsed. User may supply
96 db,user=myuser&password=mypass for non-CF targets. These values override
97 what's given the authentication from the target profile.
99 session_shared: fix reference to freed memory. Would occur if a search
100 response had non-surrogate diagnostics.
104 Route may be given for each port in frontend_net.
108 Documentation for zoom filter. Local target profiles may be specified.
110 Fixes for zoom filter.
114 First version with zoom filter.
118 Filter z3950_client may be configured to always send a close APDU
119 to backend target when connection/session is closed. This will only
120 happen if close APDU is not already sent. Enabled by configuration
121 for z3950_client (force_close).
123 Filter virt_db and multi: relay close APDU.
125 Filter virt_db and multi: relay init size parameters
126 preferredMessageSize and maximumRecordSize.
128 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
132 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
134 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
135 as determined by configure.
137 RPM: Release includes 'indexdata' name. Use indexdata in release name so
138 this package can be distinguished from other vendors.
142 Fix filter multi: relay idAuthentication parameters.
146 Add metaproxy-config for returning compiler flags, libraries.
150 Fix --with-boost=PREFIX .
154 session_shared: fix use of maintenance thread.
156 Introduce 'start' method for filters and routers. It gets called after
157 configure and after fork, but before processing. This changes API -
158 from libmetaproxy2 to libmetaproxy3.
162 session_shared: ensure backend session is closed if init rejected
165 z3950_client: fix NULL ptr reference that could occur if two clients
166 connected concurrently and if max-sockets was in effect.
170 Fix bug 3497 - Metaproxy unstable while stopping.
172 Fix bug 3495 - SEGV in SRU filter.
176 Filter multi throws diagnostic 'Present Out of Range' when
177 appropriate - rather than returning 0 records.
179 Filter virt_db: fix bad result reuse. Could happen if a result
180 was overriden and a backend did not supported named result sets.
184 Filter log: category access logs diagnostics even if searchStatus
185 or presentStatus is 'success'.
189 The SRU to Z39.50 filter does repeated Z39.50 present requests
190 to fetch all records. Needed when a Z39.50 server returns partial
191 results (due to message size limits).
195 Metaproxy now kills all child processes that are spawned by
196 modules (in case of fork, exec).
200 Debian package now installs /etc/metaproxy/metaproxy.xml which
201 includes all XML files /etc/metaproxy/filters-enabled .
202 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
206 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
207 development package to facilitate 3rd party Metaproxy modules.
209 --- 1.0.23 2010/01/04
211 Filter virt_db: Close backend filter session when Init rejected is received
212 from it (in which case it's not really closed yet). This will ensure we don't
213 run out of resources such as FDs in this case.
215 sru_z3950 filter: Accept any database (including those not listed).
217 --- 1.0.22 2009/12/03
219 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
220 later which means YAZ 3.0.47 or later.
222 --- 1.0.20 2009/11/19
224 For filter virt_db, the database is a glob pattern and the virtual
225 database sections are consulted in the order given.
227 --- 1.0.19 2009/07/08
229 For filter multi, the target (for routing) may be given as a glob-pattern.
231 More documentation for filters virt_db and multi.
233 Update schema to allow for no database in sru_z3950 filter.
235 --- 1.0.18 2009/06/30
237 Added limit filter to put sleep (penalty) for heavy use.
239 Filter frontend_net may be configured to limit the number of new connections
240 from same IP to some value (connect-max).
242 Fixed the load_balance filter.
244 --- 1.0.17 2009/06/16
246 Fix path for metaproxy executable for Debian init.d script.
248 --- 1.0.16 2009/06/10
250 SRU to Z39.50 filter honors x-username and x-password. If only
251 x-username is given that translates to open authentication (Z39.50v2). If
252 both x-username and x-password is present that translates to idPass
253 authentication (Z39.50v3).
255 New facility to change current working directory (-w).
257 Update to upstream skeleton of init.d script. Should fix bug #2619.
259 Filter session_shared now caches records (used to only cache connections
262 Filter session_shared now invalidates a Z39.50 session if a server
263 returns -1 hits. This facility was also part of yazproxy and gets around
264 a bug in Voyager-based Z39.50 servers.
266 --- 1.0.15 2008/11/18
268 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
270 --- 1.0.14 2008/06/09
272 Fixed the value of SRU record schema in searchRetrieve response. It was set
273 to a fixed value of "dc" before.
275 Serialize identical SRU requests. This is useful if HTTP client software
276 fires identical requests against metaproxy.
278 Allow Z39.50 target to be specified for SRU requests by using SRU extra
279 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
280 avoid static configuration. This facility is handled by the sru_z3950 module
281 and the z3950_client module.
283 Allow maximum number of sockets to be used for a Z39.50 client by the
284 use of SRU extra parameter x-max-sockets. This facility is handled by the
285 sru_z3950 module and the z3950_client module.
287 --- 1.0.13.1 2008/02/29
289 Simplified check for Boost libraries.
291 --- 1.0.13 2008/02/29
293 First Debian package.
295 The sru_z9350 filter now recognizes SRU parameter z-target as being
296 a ZURL of the form host/database .
298 Mergetype may be specified for filter 'multi'.
300 --- 1.0.12 2007/09/19
302 Fixed problem in Makefile WRT library specifictions. This could produce
303 linker errors (when they should not happen).
305 Fixed bug #1341: MetaProxy returning different results. Problem was that
306 fix-up of record database did not normalize the database name.
308 Documentation updates for Windows compilation.
310 --- 1.0.11 2007/06/14
312 Fixed problem with logfile being truncated.
314 --- 1.0.10 2007/05/23
316 Fixed bug #1136: Access rights not enforced.
318 Extension for log module. The log category 'access' logs more details.
319 New category 'user-access' added which is simlar to 'access' but adds
320 the Z39.50 user as for all entries in a session.
324 Added support for configurable default/force target/vhost for module Z39.50
329 Implemented filter, session_shared, which optimizes usage of Z39.50
330 sessions and result sets.
332 New filter, record_transform, which converts MARC/XML records.
334 New filter, sru_z3950, which converts SRU to Z39.50 packages.
336 New filter, load_balance, in development.
338 New filter, zeerex_xplain.
340 XML framework for config files started.
342 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
343 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
344 XML config files are checked against RNG and XML Schema's.
346 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
347 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
348 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
349 explain record to YAZ CQL-to-PQF text config file.
353 Added 'timeout' setting for filter frontend_net which specifies the number
354 of seconds a session is idle before it is closed. Default timeout is
359 Database name in records returned set for virt_db/multi filters.
361 Filter session_shared now functional.
363 Log filter can be configured to write to a given file using 'filename'
364 element. Also information category can be specified with 'category'. If
365 filename is omitted, the log filter writes to stdout. See etc/config5.xml
370 Fixed compilation on Windows.
374 Added documentation for the hidenavailable option for the multi filter.
378 Fixed bug #573: Hide errors for individual servers. If the element
379 'hideunavailable' is given in the configuration, individual servers
380 being unavailable are hidden (unless all are unavailable).
382 Fixed bug #574: Database names are recognised case-sensitively.
384 Fixed bug #567: Fix up database name in Name-Plus-Record.
386 Fixed bug #568: Update win/makefile for VS 2005.
388 Fixed bug #569: Some options throws unknown exception.
392 More information about virtual hosts. The 'etc' directory is part of the
397 Build instructions for Windows. NMake makefile part of distribution tar.
403 Filters functional: auth_simple, backend_test, frontend_net, http_file,
404 log, multi, query_rewrite, template, virt_db, z3950_client.
406 Filters in development: session_shared.
408 Pseudo-filters: template, dl
