3 zoom: database args x-name=value are passed through to backend database.
5 SRU filter: user may specify session ID that is passed to log entries
6 that follows. It is specified by using x-session-id in the SRU arguments.
8 zoom: fix null pointer reference which would occur for bad url parameter
9 inside "torus" or if url was not given.
12 Fix bug in filter session_shared where sessions would not expire
13 properly (session ttl). This in turn could make the target close the
14 connection before expected and session_shared would return diagnostic
15 2: system temporarily available.
19 zoom: new target profile setting: sortmap_field. If sortmap_field is given
20 the field is mapped to the value for the sortmap. Values not matching
21 sortmap_field are passed verbatim.
23 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
24 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
25 depending on whether RPN or CQL is actually sent to the target.
29 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
31 zoom: For content proxy authentication is stored in param name
32 "auth", instead of "authentication".
36 zoom: relay schema in SRU mode. Previously recordSchema was not affected
41 zoom: new target profile element literalTransform that holds XSLT
42 (encoded as string) for target. Only if present and non-zero length it is
43 considered present. This takes precedence over transform.
45 Don't rely on trang anymore for Git checkout builds. Configuration in etc
46 will only be properly validated if trang is available. From now on only
47 relax NC files are bundled with the source dist.
49 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
50 component was not detected when it should be.
54 z3950_client: mark non-surrogate diagnostics from backend.
56 zoom: a proxy may be specified for HTTP fetch of target profiles.
60 Honor piggyback. Makes some SRU targets behave that insist on
61 maximumRecords > 0, but also increases performance.
65 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
66 file was not update for libdir/metaproxy4 in version 1.3.2.
70 Change location of Metaproxy modules from libdir/metaproxy to
71 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
72 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
74 New facility to dump APDUs from zoom filter. Enabled by
75 <log apdu="true"/> in the zoom filter configuation.
77 zoom filter bug fix: SRU diagnostics received from backend was
78 not properly converted to Bib-1 diagnostics.
80 Package metaproxy depends on libmetaproxy4, same version.
84 zoom: fix a bug WRT passing authentication parameters to backends.
88 Fixes for windows Makefile.
92 Change major version of metaproxy library from 3 to 4. This in turn
93 makes new package names for Debian and RPM.
97 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
100 zoom: configurable element sets for record transforms.
102 zoom: the target profile based transform is specified by element_transform
103 in element torus of of the ZOOM filter configuration ; default value
104 is "pz2". Target profile based retrieval is specified by element_raw
105 in configuration. It will perform same steps, but omit the XSL transform.
106 Default value is "raw".
108 zoom: element set is omitted if not set in profile. But only if pz2
109 transform is in effect. Previously the default element set was to "F".
111 zoom: For non-CF targets database arguments are parsed. User may supply
112 db,user=myuser&password=mypass for non-CF targets. These values override
113 what's given the authentication from the target profile.
115 session_shared: fix reference to freed memory. Would occur if a search
116 response had non-surrogate diagnostics.
120 Route may be given for each port in frontend_net.
124 Documentation for zoom filter. Local target profiles may be specified.
126 Fixes for zoom filter.
130 First version with zoom filter.
134 Filter z3950_client may be configured to always send a close APDU
135 to backend target when connection/session is closed. This will only
136 happen if close APDU is not already sent. Enabled by configuration
137 for z3950_client (force_close).
139 Filter virt_db and multi: relay close APDU.
141 Filter virt_db and multi: relay init size parameters
142 preferredMessageSize and maximumRecordSize.
144 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
148 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
150 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
151 as determined by configure.
153 RPM: Release includes 'indexdata' name. Use indexdata in release name so
154 this package can be distinguished from other vendors.
158 Fix filter multi: relay idAuthentication parameters.
162 Add metaproxy-config for returning compiler flags, libraries.
166 Fix --with-boost=PREFIX .
170 session_shared: fix use of maintenance thread.
172 Introduce 'start' method for filters and routers. It gets called after
173 configure and after fork, but before processing. This changes API -
174 from libmetaproxy2 to libmetaproxy3.
178 session_shared: ensure backend session is closed if init rejected
181 z3950_client: fix NULL ptr reference that could occur if two clients
182 connected concurrently and if max-sockets was in effect.
186 Fix bug 3497 - Metaproxy unstable while stopping.
188 Fix bug 3495 - SEGV in SRU filter.
192 Filter multi throws diagnostic 'Present Out of Range' when
193 appropriate - rather than returning 0 records.
195 Filter virt_db: fix bad result reuse. Could happen if a result
196 was overriden and a backend did not supported named result sets.
200 Filter log: category access logs diagnostics even if searchStatus
201 or presentStatus is 'success'.
205 The SRU to Z39.50 filter does repeated Z39.50 present requests
206 to fetch all records. Needed when a Z39.50 server returns partial
207 results (due to message size limits).
211 Metaproxy now kills all child processes that are spawned by
212 modules (in case of fork, exec).
216 Debian package now installs /etc/metaproxy/metaproxy.xml which
217 includes all XML files /etc/metaproxy/filters-enabled .
218 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
222 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
223 development package to facilitate 3rd party Metaproxy modules.
225 --- 1.0.23 2010/01/04
227 Filter virt_db: Close backend filter session when Init rejected is received
228 from it (in which case it's not really closed yet). This will ensure we don't
229 run out of resources such as FDs in this case.
231 sru_z3950 filter: Accept any database (including those not listed).
233 --- 1.0.22 2009/12/03
235 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
236 later which means YAZ 3.0.47 or later.
238 --- 1.0.20 2009/11/19
240 For filter virt_db, the database is a glob pattern and the virtual
241 database sections are consulted in the order given.
243 --- 1.0.19 2009/07/08
245 For filter multi, the target (for routing) may be given as a glob-pattern.
247 More documentation for filters virt_db and multi.
249 Update schema to allow for no database in sru_z3950 filter.
251 --- 1.0.18 2009/06/30
253 Added limit filter to put sleep (penalty) for heavy use.
255 Filter frontend_net may be configured to limit the number of new connections
256 from same IP to some value (connect-max).
258 Fixed the load_balance filter.
260 --- 1.0.17 2009/06/16
262 Fix path for metaproxy executable for Debian init.d script.
264 --- 1.0.16 2009/06/10
266 SRU to Z39.50 filter honors x-username and x-password. If only
267 x-username is given that translates to open authentication (Z39.50v2). If
268 both x-username and x-password is present that translates to idPass
269 authentication (Z39.50v3).
271 New facility to change current working directory (-w).
273 Update to upstream skeleton of init.d script. Should fix bug #2619.
275 Filter session_shared now caches records (used to only cache connections
278 Filter session_shared now invalidates a Z39.50 session if a server
279 returns -1 hits. This facility was also part of yazproxy and gets around
280 a bug in Voyager-based Z39.50 servers.
282 --- 1.0.15 2008/11/18
284 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
286 --- 1.0.14 2008/06/09
288 Fixed the value of SRU record schema in searchRetrieve response. It was set
289 to a fixed value of "dc" before.
291 Serialize identical SRU requests. This is useful if HTTP client software
292 fires identical requests against metaproxy.
294 Allow Z39.50 target to be specified for SRU requests by using SRU extra
295 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
296 avoid static configuration. This facility is handled by the sru_z3950 module
297 and the z3950_client module.
299 Allow maximum number of sockets to be used for a Z39.50 client by the
300 use of SRU extra parameter x-max-sockets. This facility is handled by the
301 sru_z3950 module and the z3950_client module.
303 --- 1.0.13.1 2008/02/29
305 Simplified check for Boost libraries.
307 --- 1.0.13 2008/02/29
309 First Debian package.
311 The sru_z9350 filter now recognizes SRU parameter z-target as being
312 a ZURL of the form host/database .
314 Mergetype may be specified for filter 'multi'.
316 --- 1.0.12 2007/09/19
318 Fixed problem in Makefile WRT library specifictions. This could produce
319 linker errors (when they should not happen).
321 Fixed bug #1341: MetaProxy returning different results. Problem was that
322 fix-up of record database did not normalize the database name.
324 Documentation updates for Windows compilation.
326 --- 1.0.11 2007/06/14
328 Fixed problem with logfile being truncated.
330 --- 1.0.10 2007/05/23
332 Fixed bug #1136: Access rights not enforced.
334 Extension for log module. The log category 'access' logs more details.
335 New category 'user-access' added which is simlar to 'access' but adds
336 the Z39.50 user as for all entries in a session.
340 Added support for configurable default/force target/vhost for module Z39.50
345 Implemented filter, session_shared, which optimizes usage of Z39.50
346 sessions and result sets.
348 New filter, record_transform, which converts MARC/XML records.
350 New filter, sru_z3950, which converts SRU to Z39.50 packages.
352 New filter, load_balance, in development.
354 New filter, zeerex_xplain.
356 XML framework for config files started.
358 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
359 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
360 XML config files are checked against RNG and XML Schema's.
362 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
363 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
364 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
365 explain record to YAZ CQL-to-PQF text config file.
369 Added 'timeout' setting for filter frontend_net which specifies the number
370 of seconds a session is idle before it is closed. Default timeout is
375 Database name in records returned set for virt_db/multi filters.
377 Filter session_shared now functional.
379 Log filter can be configured to write to a given file using 'filename'
380 element. Also information category can be specified with 'category'. If
381 filename is omitted, the log filter writes to stdout. See etc/config5.xml
386 Fixed compilation on Windows.
390 Added documentation for the hidenavailable option for the multi filter.
394 Fixed bug #573: Hide errors for individual servers. If the element
395 'hideunavailable' is given in the configuration, individual servers
396 being unavailable are hidden (unless all are unavailable).
398 Fixed bug #574: Database names are recognised case-sensitively.
400 Fixed bug #567: Fix up database name in Name-Plus-Record.
402 Fixed bug #568: Update win/makefile for VS 2005.
404 Fixed bug #569: Some options throws unknown exception.
408 More information about virtual hosts. The 'etc' directory is part of the
413 Build instructions for Windows. NMake makefile part of distribution tar.
419 Filters functional: auth_simple, backend_test, frontend_net, http_file,
420 log, multi, query_rewrite, template, virt_db, z3950_client.
422 Filters in development: session_shared.
