3 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
4 makes sense to the zoom module itself).
8 zoom: realm may be given as part of database.
12 Fix Origin class assigment method; was removd by mistake in 1.3.12.
16 zoom: database args x-name=value are passed through to backend database.
18 SRU filter: user may specify session ID that is passed to log entries
19 that follows. It is specified by using x-session-id in the SRU arguments.
21 zoom: fix null pointer reference which would occur for bad url parameter
22 inside "torus" or if url was not given.
25 Fix bug in filter session_shared where sessions would not expire
26 properly (session ttl). This in turn could make the target close the
27 connection before expected and session_shared would return diagnostic
28 2: system temporarily available.
32 zoom: new target profile setting: sortmap_field. If sortmap_field is given
33 the field is mapped to the value for the sortmap. Values not matching
34 sortmap_field are passed verbatim.
36 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
37 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
38 depending on whether RPN or CQL is actually sent to the target.
42 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
44 zoom: For content proxy authentication is stored in param name
45 "auth", instead of "authentication".
49 zoom: relay schema in SRU mode. Previously recordSchema was not affected
54 zoom: new target profile element literalTransform that holds XSLT
55 (encoded as string) for target. Only if present and non-zero length it is
56 considered present. This takes precedence over transform.
58 Don't rely on trang anymore for Git checkout builds. Configuration in etc
59 will only be properly validated if trang is available. From now on only
60 relax NC files are bundled with the source dist.
62 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
63 component was not detected when it should be.
67 z3950_client: mark non-surrogate diagnostics from backend.
69 zoom: a proxy may be specified for HTTP fetch of target profiles.
73 Honor piggyback. Makes some SRU targets behave that insist on
74 maximumRecords > 0, but also increases performance.
78 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
79 file was not update for libdir/metaproxy4 in version 1.3.2.
83 Change location of Metaproxy modules from libdir/metaproxy to
84 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
85 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
87 New facility to dump APDUs from zoom filter. Enabled by
88 <log apdu="true"/> in the zoom filter configuation.
90 zoom filter bug fix: SRU diagnostics received from backend was
91 not properly converted to Bib-1 diagnostics.
93 Package metaproxy depends on libmetaproxy4, same version.
97 zoom: fix a bug WRT passing authentication parameters to backends.
101 Fixes for windows Makefile.
103 --- 1.2.10 2011/07/25
105 Change major version of metaproxy library from 3 to 4. This in turn
106 makes new package names for Debian and RPM.
110 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
113 zoom: configurable element sets for record transforms.
115 zoom: the target profile based transform is specified by element_transform
116 in element torus of of the ZOOM filter configuration ; default value
117 is "pz2". Target profile based retrieval is specified by element_raw
118 in configuration. It will perform same steps, but omit the XSL transform.
119 Default value is "raw".
121 zoom: element set is omitted if not set in profile. But only if pz2
122 transform is in effect. Previously the default element set was to "F".
124 zoom: For non-CF targets database arguments are parsed. User may supply
125 db,user=myuser&password=mypass for non-CF targets. These values override
126 what's given the authentication from the target profile.
128 session_shared: fix reference to freed memory. Would occur if a search
129 response had non-surrogate diagnostics.
133 Route may be given for each port in frontend_net.
137 Documentation for zoom filter. Local target profiles may be specified.
139 Fixes for zoom filter.
143 First version with zoom filter.
147 Filter z3950_client may be configured to always send a close APDU
148 to backend target when connection/session is closed. This will only
149 happen if close APDU is not already sent. Enabled by configuration
150 for z3950_client (force_close).
152 Filter virt_db and multi: relay close APDU.
154 Filter virt_db and multi: relay init size parameters
155 preferredMessageSize and maximumRecordSize.
157 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
161 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
163 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
164 as determined by configure.
166 RPM: Release includes 'indexdata' name. Use indexdata in release name so
167 this package can be distinguished from other vendors.
171 Fix filter multi: relay idAuthentication parameters.
175 Add metaproxy-config for returning compiler flags, libraries.
179 Fix --with-boost=PREFIX .
183 session_shared: fix use of maintenance thread.
185 Introduce 'start' method for filters and routers. It gets called after
186 configure and after fork, but before processing. This changes API -
187 from libmetaproxy2 to libmetaproxy3.
191 session_shared: ensure backend session is closed if init rejected
194 z3950_client: fix NULL ptr reference that could occur if two clients
195 connected concurrently and if max-sockets was in effect.
199 Fix bug 3497 - Metaproxy unstable while stopping.
201 Fix bug 3495 - SEGV in SRU filter.
205 Filter multi throws diagnostic 'Present Out of Range' when
206 appropriate - rather than returning 0 records.
208 Filter virt_db: fix bad result reuse. Could happen if a result
209 was overriden and a backend did not supported named result sets.
213 Filter log: category access logs diagnostics even if searchStatus
214 or presentStatus is 'success'.
218 The SRU to Z39.50 filter does repeated Z39.50 present requests
219 to fetch all records. Needed when a Z39.50 server returns partial
220 results (due to message size limits).
224 Metaproxy now kills all child processes that are spawned by
225 modules (in case of fork, exec).
229 Debian package now installs /etc/metaproxy/metaproxy.xml which
230 includes all XML files /etc/metaproxy/filters-enabled .
231 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
235 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
236 development package to facilitate 3rd party Metaproxy modules.
238 --- 1.0.23 2010/01/04
240 Filter virt_db: Close backend filter session when Init rejected is received
241 from it (in which case it's not really closed yet). This will ensure we don't
242 run out of resources such as FDs in this case.
244 sru_z3950 filter: Accept any database (including those not listed).
246 --- 1.0.22 2009/12/03
248 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
249 later which means YAZ 3.0.47 or later.
251 --- 1.0.20 2009/11/19
253 For filter virt_db, the database is a glob pattern and the virtual
254 database sections are consulted in the order given.
256 --- 1.0.19 2009/07/08
258 For filter multi, the target (for routing) may be given as a glob-pattern.
260 More documentation for filters virt_db and multi.
262 Update schema to allow for no database in sru_z3950 filter.
264 --- 1.0.18 2009/06/30
266 Added limit filter to put sleep (penalty) for heavy use.
268 Filter frontend_net may be configured to limit the number of new connections
269 from same IP to some value (connect-max).
271 Fixed the load_balance filter.
273 --- 1.0.17 2009/06/16
275 Fix path for metaproxy executable for Debian init.d script.
277 --- 1.0.16 2009/06/10
279 SRU to Z39.50 filter honors x-username and x-password. If only
280 x-username is given that translates to open authentication (Z39.50v2). If
281 both x-username and x-password is present that translates to idPass
282 authentication (Z39.50v3).
284 New facility to change current working directory (-w).
286 Update to upstream skeleton of init.d script. Should fix bug #2619.
288 Filter session_shared now caches records (used to only cache connections
291 Filter session_shared now invalidates a Z39.50 session if a server
292 returns -1 hits. This facility was also part of yazproxy and gets around
293 a bug in Voyager-based Z39.50 servers.
295 --- 1.0.15 2008/11/18
297 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
299 --- 1.0.14 2008/06/09
301 Fixed the value of SRU record schema in searchRetrieve response. It was set
302 to a fixed value of "dc" before.
304 Serialize identical SRU requests. This is useful if HTTP client software
305 fires identical requests against metaproxy.
307 Allow Z39.50 target to be specified for SRU requests by using SRU extra
308 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
309 avoid static configuration. This facility is handled by the sru_z3950 module
310 and the z3950_client module.
312 Allow maximum number of sockets to be used for a Z39.50 client by the
313 use of SRU extra parameter x-max-sockets. This facility is handled by the
314 sru_z3950 module and the z3950_client module.
316 --- 1.0.13.1 2008/02/29
318 Simplified check for Boost libraries.
320 --- 1.0.13 2008/02/29
322 First Debian package.
324 The sru_z9350 filter now recognizes SRU parameter z-target as being
325 a ZURL of the form host/database .
327 Mergetype may be specified for filter 'multi'.
329 --- 1.0.12 2007/09/19
331 Fixed problem in Makefile WRT library specifictions. This could produce
332 linker errors (when they should not happen).
334 Fixed bug #1341: MetaProxy returning different results. Problem was that
335 fix-up of record database did not normalize the database name.
337 Documentation updates for Windows compilation.
339 --- 1.0.11 2007/06/14
341 Fixed problem with logfile being truncated.
343 --- 1.0.10 2007/05/23
345 Fixed bug #1136: Access rights not enforced.
347 Extension for log module. The log category 'access' logs more details.
348 New category 'user-access' added which is simlar to 'access' but adds
349 the Z39.50 user as for all entries in a session.
353 Added support for configurable default/force target/vhost for module Z39.50
358 Implemented filter, session_shared, which optimizes usage of Z39.50
359 sessions and result sets.
361 New filter, record_transform, which converts MARC/XML records.
363 New filter, sru_z3950, which converts SRU to Z39.50 packages.
365 New filter, load_balance, in development.
367 New filter, zeerex_xplain.
369 XML framework for config files started.
371 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
372 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
373 XML config files are checked against RNG and XML Schema's.
375 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
376 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
377 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
378 explain record to YAZ CQL-to-PQF text config file.
382 Added 'timeout' setting for filter frontend_net which specifies the number
383 of seconds a session is idle before it is closed. Default timeout is
388 Database name in records returned set for virt_db/multi filters.
390 Filter session_shared now functional.
392 Log filter can be configured to write to a given file using 'filename'
393 element. Also information category can be specified with 'category'. If
394 filename is omitted, the log filter writes to stdout. See etc/config5.xml
399 Fixed compilation on Windows.
403 Added documentation for the hidenavailable option for the multi filter.
407 Fixed bug #573: Hide errors for individual servers. If the element
408 'hideunavailable' is given in the configuration, individual servers
409 being unavailable are hidden (unless all are unavailable).
411 Fixed bug #574: Database names are recognised case-sensitively.
413 Fixed bug #567: Fix up database name in Name-Plus-Record.
415 Fixed bug #568: Update win/makefile for VS 2005.
417 Fixed bug #569: Some options throws unknown exception.
421 More information about virtual hosts. The 'etc' directory is part of the
426 Build instructions for Windows. NMake makefile part of distribution tar.
432 Filters functional: auth_simple, backend_test, frontend_net, http_file,
433 log, multi, query_rewrite, template, virt_db, z3950_client.
435 Filters in development: session_shared.
