3 Fix Origin class assigment method; was removd by mistake in 1.3.12.
7 zoom: database args x-name=value are passed through to backend database.
9 SRU filter: user may specify session ID that is passed to log entries
10 that follows. It is specified by using x-session-id in the SRU arguments.
12 zoom: fix null pointer reference which would occur for bad url parameter
13 inside "torus" or if url was not given.
16 Fix bug in filter session_shared where sessions would not expire
17 properly (session ttl). This in turn could make the target close the
18 connection before expected and session_shared would return diagnostic
19 2: system temporarily available.
23 zoom: new target profile setting: sortmap_field. If sortmap_field is given
24 the field is mapped to the value for the sortmap. Values not matching
25 sortmap_field are passed verbatim.
27 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
28 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
29 depending on whether RPN or CQL is actually sent to the target.
33 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
35 zoom: For content proxy authentication is stored in param name
36 "auth", instead of "authentication".
40 zoom: relay schema in SRU mode. Previously recordSchema was not affected
45 zoom: new target profile element literalTransform that holds XSLT
46 (encoded as string) for target. Only if present and non-zero length it is
47 considered present. This takes precedence over transform.
49 Don't rely on trang anymore for Git checkout builds. Configuration in etc
50 will only be properly validated if trang is available. From now on only
51 relax NC files are bundled with the source dist.
53 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
54 component was not detected when it should be.
58 z3950_client: mark non-surrogate diagnostics from backend.
60 zoom: a proxy may be specified for HTTP fetch of target profiles.
64 Honor piggyback. Makes some SRU targets behave that insist on
65 maximumRecords > 0, but also increases performance.
69 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
70 file was not update for libdir/metaproxy4 in version 1.3.2.
74 Change location of Metaproxy modules from libdir/metaproxy to
75 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
76 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
78 New facility to dump APDUs from zoom filter. Enabled by
79 <log apdu="true"/> in the zoom filter configuation.
81 zoom filter bug fix: SRU diagnostics received from backend was
82 not properly converted to Bib-1 diagnostics.
84 Package metaproxy depends on libmetaproxy4, same version.
88 zoom: fix a bug WRT passing authentication parameters to backends.
92 Fixes for windows Makefile.
96 Change major version of metaproxy library from 3 to 4. This in turn
97 makes new package names for Debian and RPM.
101 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
104 zoom: configurable element sets for record transforms.
106 zoom: the target profile based transform is specified by element_transform
107 in element torus of of the ZOOM filter configuration ; default value
108 is "pz2". Target profile based retrieval is specified by element_raw
109 in configuration. It will perform same steps, but omit the XSL transform.
110 Default value is "raw".
112 zoom: element set is omitted if not set in profile. But only if pz2
113 transform is in effect. Previously the default element set was to "F".
115 zoom: For non-CF targets database arguments are parsed. User may supply
116 db,user=myuser&password=mypass for non-CF targets. These values override
117 what's given the authentication from the target profile.
119 session_shared: fix reference to freed memory. Would occur if a search
120 response had non-surrogate diagnostics.
124 Route may be given for each port in frontend_net.
128 Documentation for zoom filter. Local target profiles may be specified.
130 Fixes for zoom filter.
134 First version with zoom filter.
138 Filter z3950_client may be configured to always send a close APDU
139 to backend target when connection/session is closed. This will only
140 happen if close APDU is not already sent. Enabled by configuration
141 for z3950_client (force_close).
143 Filter virt_db and multi: relay close APDU.
145 Filter virt_db and multi: relay init size parameters
146 preferredMessageSize and maximumRecordSize.
148 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
152 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
154 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
155 as determined by configure.
157 RPM: Release includes 'indexdata' name. Use indexdata in release name so
158 this package can be distinguished from other vendors.
162 Fix filter multi: relay idAuthentication parameters.
166 Add metaproxy-config for returning compiler flags, libraries.
170 Fix --with-boost=PREFIX .
174 session_shared: fix use of maintenance thread.
176 Introduce 'start' method for filters and routers. It gets called after
177 configure and after fork, but before processing. This changes API -
178 from libmetaproxy2 to libmetaproxy3.
182 session_shared: ensure backend session is closed if init rejected
185 z3950_client: fix NULL ptr reference that could occur if two clients
186 connected concurrently and if max-sockets was in effect.
190 Fix bug 3497 - Metaproxy unstable while stopping.
192 Fix bug 3495 - SEGV in SRU filter.
196 Filter multi throws diagnostic 'Present Out of Range' when
197 appropriate - rather than returning 0 records.
199 Filter virt_db: fix bad result reuse. Could happen if a result
200 was overriden and a backend did not supported named result sets.
204 Filter log: category access logs diagnostics even if searchStatus
205 or presentStatus is 'success'.
209 The SRU to Z39.50 filter does repeated Z39.50 present requests
210 to fetch all records. Needed when a Z39.50 server returns partial
211 results (due to message size limits).
215 Metaproxy now kills all child processes that are spawned by
216 modules (in case of fork, exec).
220 Debian package now installs /etc/metaproxy/metaproxy.xml which
221 includes all XML files /etc/metaproxy/filters-enabled .
222 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
226 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
227 development package to facilitate 3rd party Metaproxy modules.
229 --- 1.0.23 2010/01/04
231 Filter virt_db: Close backend filter session when Init rejected is received
232 from it (in which case it's not really closed yet). This will ensure we don't
233 run out of resources such as FDs in this case.
235 sru_z3950 filter: Accept any database (including those not listed).
237 --- 1.0.22 2009/12/03
239 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
240 later which means YAZ 3.0.47 or later.
242 --- 1.0.20 2009/11/19
244 For filter virt_db, the database is a glob pattern and the virtual
245 database sections are consulted in the order given.
247 --- 1.0.19 2009/07/08
249 For filter multi, the target (for routing) may be given as a glob-pattern.
251 More documentation for filters virt_db and multi.
253 Update schema to allow for no database in sru_z3950 filter.
255 --- 1.0.18 2009/06/30
257 Added limit filter to put sleep (penalty) for heavy use.
259 Filter frontend_net may be configured to limit the number of new connections
260 from same IP to some value (connect-max).
262 Fixed the load_balance filter.
264 --- 1.0.17 2009/06/16
266 Fix path for metaproxy executable for Debian init.d script.
268 --- 1.0.16 2009/06/10
270 SRU to Z39.50 filter honors x-username and x-password. If only
271 x-username is given that translates to open authentication (Z39.50v2). If
272 both x-username and x-password is present that translates to idPass
273 authentication (Z39.50v3).
275 New facility to change current working directory (-w).
277 Update to upstream skeleton of init.d script. Should fix bug #2619.
279 Filter session_shared now caches records (used to only cache connections
282 Filter session_shared now invalidates a Z39.50 session if a server
283 returns -1 hits. This facility was also part of yazproxy and gets around
284 a bug in Voyager-based Z39.50 servers.
286 --- 1.0.15 2008/11/18
288 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
290 --- 1.0.14 2008/06/09
292 Fixed the value of SRU record schema in searchRetrieve response. It was set
293 to a fixed value of "dc" before.
295 Serialize identical SRU requests. This is useful if HTTP client software
296 fires identical requests against metaproxy.
298 Allow Z39.50 target to be specified for SRU requests by using SRU extra
299 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
300 avoid static configuration. This facility is handled by the sru_z3950 module
301 and the z3950_client module.
303 Allow maximum number of sockets to be used for a Z39.50 client by the
304 use of SRU extra parameter x-max-sockets. This facility is handled by the
305 sru_z3950 module and the z3950_client module.
307 --- 1.0.13.1 2008/02/29
309 Simplified check for Boost libraries.
311 --- 1.0.13 2008/02/29
313 First Debian package.
315 The sru_z9350 filter now recognizes SRU parameter z-target as being
316 a ZURL of the form host/database .
318 Mergetype may be specified for filter 'multi'.
320 --- 1.0.12 2007/09/19
322 Fixed problem in Makefile WRT library specifictions. This could produce
323 linker errors (when they should not happen).
325 Fixed bug #1341: MetaProxy returning different results. Problem was that
326 fix-up of record database did not normalize the database name.
328 Documentation updates for Windows compilation.
330 --- 1.0.11 2007/06/14
332 Fixed problem with logfile being truncated.
334 --- 1.0.10 2007/05/23
336 Fixed bug #1136: Access rights not enforced.
338 Extension for log module. The log category 'access' logs more details.
339 New category 'user-access' added which is simlar to 'access' but adds
340 the Z39.50 user as for all entries in a session.
344 Added support for configurable default/force target/vhost for module Z39.50
349 Implemented filter, session_shared, which optimizes usage of Z39.50
350 sessions and result sets.
352 New filter, record_transform, which converts MARC/XML records.
354 New filter, sru_z3950, which converts SRU to Z39.50 packages.
356 New filter, load_balance, in development.
358 New filter, zeerex_xplain.
360 XML framework for config files started.
362 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
363 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
364 XML config files are checked against RNG and XML Schema's.
366 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
367 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
368 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
369 explain record to YAZ CQL-to-PQF text config file.
373 Added 'timeout' setting for filter frontend_net which specifies the number
374 of seconds a session is idle before it is closed. Default timeout is
379 Database name in records returned set for virt_db/multi filters.
381 Filter session_shared now functional.
383 Log filter can be configured to write to a given file using 'filename'
384 element. Also information category can be specified with 'category'. If
385 filename is omitted, the log filter writes to stdout. See etc/config5.xml
390 Fixed compilation on Windows.
394 Added documentation for the hidenavailable option for the multi filter.
398 Fixed bug #573: Hide errors for individual servers. If the element
399 'hideunavailable' is given in the configuration, individual servers
400 being unavailable are hidden (unless all are unavailable).
402 Fixed bug #574: Database names are recognised case-sensitively.
404 Fixed bug #567: Fix up database name in Name-Plus-Record.
406 Fixed bug #568: Update win/makefile for VS 2005.
408 Fixed bug #569: Some options throws unknown exception.
412 More information about virtual hosts. The 'etc' directory is part of the
417 Build instructions for Windows. NMake makefile part of distribution tar.
423 Filters functional: auth_simple, backend_test, frontend_net, http_file,
424 log, multi, query_rewrite, template, virt_db, z3950_client.
426 Filters in development: session_shared.
