3 zoom: realm may be given as part of database.
7 Fix Origin class assigment method; was removd by mistake in 1.3.12.
11 zoom: database args x-name=value are passed through to backend database.
13 SRU filter: user may specify session ID that is passed to log entries
14 that follows. It is specified by using x-session-id in the SRU arguments.
16 zoom: fix null pointer reference which would occur for bad url parameter
17 inside "torus" or if url was not given.
20 Fix bug in filter session_shared where sessions would not expire
21 properly (session ttl). This in turn could make the target close the
22 connection before expected and session_shared would return diagnostic
23 2: system temporarily available.
27 zoom: new target profile setting: sortmap_field. If sortmap_field is given
28 the field is mapped to the value for the sortmap. Values not matching
29 sortmap_field are passed verbatim.
31 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
32 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
33 depending on whether RPN or CQL is actually sent to the target.
37 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
39 zoom: For content proxy authentication is stored in param name
40 "auth", instead of "authentication".
44 zoom: relay schema in SRU mode. Previously recordSchema was not affected
49 zoom: new target profile element literalTransform that holds XSLT
50 (encoded as string) for target. Only if present and non-zero length it is
51 considered present. This takes precedence over transform.
53 Don't rely on trang anymore for Git checkout builds. Configuration in etc
54 will only be properly validated if trang is available. From now on only
55 relax NC files are bundled with the source dist.
57 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
58 component was not detected when it should be.
62 z3950_client: mark non-surrogate diagnostics from backend.
64 zoom: a proxy may be specified for HTTP fetch of target profiles.
68 Honor piggyback. Makes some SRU targets behave that insist on
69 maximumRecords > 0, but also increases performance.
73 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
74 file was not update for libdir/metaproxy4 in version 1.3.2.
78 Change location of Metaproxy modules from libdir/metaproxy to
79 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
80 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
82 New facility to dump APDUs from zoom filter. Enabled by
83 <log apdu="true"/> in the zoom filter configuation.
85 zoom filter bug fix: SRU diagnostics received from backend was
86 not properly converted to Bib-1 diagnostics.
88 Package metaproxy depends on libmetaproxy4, same version.
92 zoom: fix a bug WRT passing authentication parameters to backends.
96 Fixes for windows Makefile.
100 Change major version of metaproxy library from 3 to 4. This in turn
101 makes new package names for Debian and RPM.
105 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
108 zoom: configurable element sets for record transforms.
110 zoom: the target profile based transform is specified by element_transform
111 in element torus of of the ZOOM filter configuration ; default value
112 is "pz2". Target profile based retrieval is specified by element_raw
113 in configuration. It will perform same steps, but omit the XSL transform.
114 Default value is "raw".
116 zoom: element set is omitted if not set in profile. But only if pz2
117 transform is in effect. Previously the default element set was to "F".
119 zoom: For non-CF targets database arguments are parsed. User may supply
120 db,user=myuser&password=mypass for non-CF targets. These values override
121 what's given the authentication from the target profile.
123 session_shared: fix reference to freed memory. Would occur if a search
124 response had non-surrogate diagnostics.
128 Route may be given for each port in frontend_net.
132 Documentation for zoom filter. Local target profiles may be specified.
134 Fixes for zoom filter.
138 First version with zoom filter.
142 Filter z3950_client may be configured to always send a close APDU
143 to backend target when connection/session is closed. This will only
144 happen if close APDU is not already sent. Enabled by configuration
145 for z3950_client (force_close).
147 Filter virt_db and multi: relay close APDU.
149 Filter virt_db and multi: relay init size parameters
150 preferredMessageSize and maximumRecordSize.
152 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
156 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
158 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
159 as determined by configure.
161 RPM: Release includes 'indexdata' name. Use indexdata in release name so
162 this package can be distinguished from other vendors.
166 Fix filter multi: relay idAuthentication parameters.
170 Add metaproxy-config for returning compiler flags, libraries.
174 Fix --with-boost=PREFIX .
178 session_shared: fix use of maintenance thread.
180 Introduce 'start' method for filters and routers. It gets called after
181 configure and after fork, but before processing. This changes API -
182 from libmetaproxy2 to libmetaproxy3.
186 session_shared: ensure backend session is closed if init rejected
189 z3950_client: fix NULL ptr reference that could occur if two clients
190 connected concurrently and if max-sockets was in effect.
194 Fix bug 3497 - Metaproxy unstable while stopping.
196 Fix bug 3495 - SEGV in SRU filter.
200 Filter multi throws diagnostic 'Present Out of Range' when
201 appropriate - rather than returning 0 records.
203 Filter virt_db: fix bad result reuse. Could happen if a result
204 was overriden and a backend did not supported named result sets.
208 Filter log: category access logs diagnostics even if searchStatus
209 or presentStatus is 'success'.
213 The SRU to Z39.50 filter does repeated Z39.50 present requests
214 to fetch all records. Needed when a Z39.50 server returns partial
215 results (due to message size limits).
219 Metaproxy now kills all child processes that are spawned by
220 modules (in case of fork, exec).
224 Debian package now installs /etc/metaproxy/metaproxy.xml which
225 includes all XML files /etc/metaproxy/filters-enabled .
226 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
230 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
231 development package to facilitate 3rd party Metaproxy modules.
233 --- 1.0.23 2010/01/04
235 Filter virt_db: Close backend filter session when Init rejected is received
236 from it (in which case it's not really closed yet). This will ensure we don't
237 run out of resources such as FDs in this case.
239 sru_z3950 filter: Accept any database (including those not listed).
241 --- 1.0.22 2009/12/03
243 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
244 later which means YAZ 3.0.47 or later.
246 --- 1.0.20 2009/11/19
248 For filter virt_db, the database is a glob pattern and the virtual
249 database sections are consulted in the order given.
251 --- 1.0.19 2009/07/08
253 For filter multi, the target (for routing) may be given as a glob-pattern.
255 More documentation for filters virt_db and multi.
257 Update schema to allow for no database in sru_z3950 filter.
259 --- 1.0.18 2009/06/30
261 Added limit filter to put sleep (penalty) for heavy use.
263 Filter frontend_net may be configured to limit the number of new connections
264 from same IP to some value (connect-max).
266 Fixed the load_balance filter.
268 --- 1.0.17 2009/06/16
270 Fix path for metaproxy executable for Debian init.d script.
272 --- 1.0.16 2009/06/10
274 SRU to Z39.50 filter honors x-username and x-password. If only
275 x-username is given that translates to open authentication (Z39.50v2). If
276 both x-username and x-password is present that translates to idPass
277 authentication (Z39.50v3).
279 New facility to change current working directory (-w).
281 Update to upstream skeleton of init.d script. Should fix bug #2619.
283 Filter session_shared now caches records (used to only cache connections
286 Filter session_shared now invalidates a Z39.50 session if a server
287 returns -1 hits. This facility was also part of yazproxy and gets around
288 a bug in Voyager-based Z39.50 servers.
290 --- 1.0.15 2008/11/18
292 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
294 --- 1.0.14 2008/06/09
296 Fixed the value of SRU record schema in searchRetrieve response. It was set
297 to a fixed value of "dc" before.
299 Serialize identical SRU requests. This is useful if HTTP client software
300 fires identical requests against metaproxy.
302 Allow Z39.50 target to be specified for SRU requests by using SRU extra
303 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
304 avoid static configuration. This facility is handled by the sru_z3950 module
305 and the z3950_client module.
307 Allow maximum number of sockets to be used for a Z39.50 client by the
308 use of SRU extra parameter x-max-sockets. This facility is handled by the
309 sru_z3950 module and the z3950_client module.
311 --- 1.0.13.1 2008/02/29
313 Simplified check for Boost libraries.
315 --- 1.0.13 2008/02/29
317 First Debian package.
319 The sru_z9350 filter now recognizes SRU parameter z-target as being
320 a ZURL of the form host/database .
322 Mergetype may be specified for filter 'multi'.
324 --- 1.0.12 2007/09/19
326 Fixed problem in Makefile WRT library specifictions. This could produce
327 linker errors (when they should not happen).
329 Fixed bug #1341: MetaProxy returning different results. Problem was that
330 fix-up of record database did not normalize the database name.
332 Documentation updates for Windows compilation.
334 --- 1.0.11 2007/06/14
336 Fixed problem with logfile being truncated.
338 --- 1.0.10 2007/05/23
340 Fixed bug #1136: Access rights not enforced.
342 Extension for log module. The log category 'access' logs more details.
343 New category 'user-access' added which is simlar to 'access' but adds
344 the Z39.50 user as for all entries in a session.
348 Added support for configurable default/force target/vhost for module Z39.50
353 Implemented filter, session_shared, which optimizes usage of Z39.50
354 sessions and result sets.
356 New filter, record_transform, which converts MARC/XML records.
358 New filter, sru_z3950, which converts SRU to Z39.50 packages.
360 New filter, load_balance, in development.
362 New filter, zeerex_xplain.
364 XML framework for config files started.
366 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
367 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
368 XML config files are checked against RNG and XML Schema's.
370 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
371 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
372 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
373 explain record to YAZ CQL-to-PQF text config file.
377 Added 'timeout' setting for filter frontend_net which specifies the number
378 of seconds a session is idle before it is closed. Default timeout is
383 Database name in records returned set for virt_db/multi filters.
385 Filter session_shared now functional.
387 Log filter can be configured to write to a given file using 'filename'
388 element. Also information category can be specified with 'category'. If
389 filename is omitted, the log filter writes to stdout. See etc/config5.xml
394 Fixed compilation on Windows.
398 Added documentation for the hidenavailable option for the multi filter.
402 Fixed bug #573: Hide errors for individual servers. If the element
403 'hideunavailable' is given in the configuration, individual servers
404 being unavailable are hidden (unless all are unavailable).
406 Fixed bug #574: Database names are recognised case-sensitively.
408 Fixed bug #567: Fix up database name in Name-Plus-Record.
410 Fixed bug #568: Update win/makefile for VS 2005.
412 Fixed bug #569: Some options throws unknown exception.
416 More information about virtual hosts. The 'etc' directory is part of the
421 Build instructions for Windows. NMake makefile part of distribution tar.
427 Filters functional: auth_simple, backend_test, frontend_net, http_file,
428 log, multi, query_rewrite, template, virt_db, z3950_client.
430 Filters in development: session_shared.
