3 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
5 zoom: For content proxy authentication is stored in param name
6 "auth", instead of "authentication".
10 zoom: relay schema in SRU mode. Previously recordSchema was not affected
15 zoom: new target profile element literalTransform that holds XSLT
16 (encoded as string) for target. Only if present and non-zero length it is
17 considered present. This takes precedence over transform.
19 Don't rely on trang anymore for Git checkout builds. Configuration in etc
20 will only be properly validated if trang is available. From now on only
21 relax NC files are bundled with the source dist.
23 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
24 component was not detected when it should be.
28 z3950_client: mark non-surrogate diagnostics from backend.
30 zoom: a proxy may be specified for HTTP fetch of target profiles.
34 Honor piggyback. Makes some SRU targets behave that insist on
35 maximumRecords > 0, but also increases performance.
39 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
40 file was not update for libdir/metaproxy4 in version 1.3.2.
44 Change location of Metaproxy modules from libdir/metaproxy to
45 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
46 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
48 New facility to dump APDUs from zoom filter. Enabled by
49 <log apdu="true"/> in the zoom filter configuation.
51 zoom filter bug fix: SRU diagnostics received from backend was
52 not properly converted to Bib-1 diagnostics.
54 Package metaproxy depends on libmetaproxy4, same version.
58 zoom: fix a bug WRT passing authentication parameters to backends.
62 Fixes for windows Makefile.
66 Change major version of metaproxy library from 3 to 4. This in turn
67 makes new package names for Debian and RPM.
71 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
74 zoom: configurable element sets for record transforms.
76 zoom: the target profile based transform is specified by element_transform
77 in element torus of of the ZOOM filter configuration ; default value
78 is "pz2". Target profile based retrieval is specified by element_raw
79 in configuration. It will perform same steps, but omit the XSL transform.
80 Default value is "raw".
82 zoom: element set is omitted if not set in profile. But only if pz2
83 transform is in effect. Previously the default element set was to "F".
85 zoom: For non-CF targets database arguments are parsed. User may supply
86 db,user=myuser&password=mypass for non-CF targets. These values override
87 what's given the authentication from the target profile.
89 session_shared: fix reference to freed memory. Would occur if a search
90 response had non-surrogate diagnostics.
94 Route may be given for each port in frontend_net.
98 Documentation for zoom filter. Local target profiles may be specified.
100 Fixes for zoom filter.
104 First version with zoom filter.
108 Filter z3950_client may be configured to always send a close APDU
109 to backend target when connection/session is closed. This will only
110 happen if close APDU is not already sent. Enabled by configuration
111 for z3950_client (force_close).
113 Filter virt_db and multi: relay close APDU.
115 Filter virt_db and multi: relay init size parameters
116 preferredMessageSize and maximumRecordSize.
118 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
122 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
124 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
125 as determined by configure.
127 RPM: Release includes 'indexdata' name. Use indexdata in release name so
128 this package can be distinguished from other vendors.
132 Fix filter multi: relay idAuthentication parameters.
136 Add metaproxy-config for returning compiler flags, libraries.
140 Fix --with-boost=PREFIX .
144 session_shared: fix use of maintenance thread.
146 Introduce 'start' method for filters and routers. It gets called after
147 configure and after fork, but before processing. This changes API -
148 from libmetaproxy2 to libmetaproxy3.
152 session_shared: ensure backend session is closed if init rejected
155 z3950_client: fix NULL ptr reference that could occur if two clients
156 connected concurrently and if max-sockets was in effect.
160 Fix bug 3497 - Metaproxy unstable while stopping.
162 Fix bug 3495 - SEGV in SRU filter.
166 Filter multi throws diagnostic 'Present Out of Range' when
167 appropriate - rather than returning 0 records.
169 Filter virt_db: fix bad result reuse. Could happen if a result
170 was overriden and a backend did not supported named result sets.
174 Filter log: category access logs diagnostics even if searchStatus
175 or presentStatus is 'success'.
179 The SRU to Z39.50 filter does repeated Z39.50 present requests
180 to fetch all records. Needed when a Z39.50 server returns partial
181 results (due to message size limits).
185 Metaproxy now kills all child processes that are spawned by
186 modules (in case of fork, exec).
190 Debian package now installs /etc/metaproxy/metaproxy.xml which
191 includes all XML files /etc/metaproxy/filters-enabled .
192 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
196 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
197 development package to facilitate 3rd party Metaproxy modules.
199 --- 1.0.23 2010/01/04
201 Filter virt_db: Close backend filter session when Init rejected is received
202 from it (in which case it's not really closed yet). This will ensure we don't
203 run out of resources such as FDs in this case.
205 sru_z3950 filter: Accept any database (including those not listed).
207 --- 1.0.22 2009/12/03
209 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
210 later which means YAZ 3.0.47 or later.
212 --- 1.0.20 2009/11/19
214 For filter virt_db, the database is a glob pattern and the virtual
215 database sections are consulted in the order given.
217 --- 1.0.19 2009/07/08
219 For filter multi, the target (for routing) may be given as a glob-pattern.
221 More documentation for filters virt_db and multi.
223 Update schema to allow for no database in sru_z3950 filter.
225 --- 1.0.18 2009/06/30
227 Added limit filter to put sleep (penalty) for heavy use.
229 Filter frontend_net may be configured to limit the number of new connections
230 from same IP to some value (connect-max).
232 Fixed the load_balance filter.
234 --- 1.0.17 2009/06/16
236 Fix path for metaproxy executable for Debian init.d script.
238 --- 1.0.16 2009/06/10
240 SRU to Z39.50 filter honors x-username and x-password. If only
241 x-username is given that translates to open authentication (Z39.50v2). If
242 both x-username and x-password is present that translates to idPass
243 authentication (Z39.50v3).
245 New facility to change current working directory (-w).
247 Update to upstream skeleton of init.d script. Should fix bug #2619.
249 Filter session_shared now caches records (used to only cache connections
252 Filter session_shared now invalidates a Z39.50 session if a server
253 returns -1 hits. This facility was also part of yazproxy and gets around
254 a bug in Voyager-based Z39.50 servers.
256 --- 1.0.15 2008/11/18
258 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
260 --- 1.0.14 2008/06/09
262 Fixed the value of SRU record schema in searchRetrieve response. It was set
263 to a fixed value of "dc" before.
265 Serialize identical SRU requests. This is useful if HTTP client software
266 fires identical requests against metaproxy.
268 Allow Z39.50 target to be specified for SRU requests by using SRU extra
269 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
270 avoid static configuration. This facility is handled by the sru_z3950 module
271 and the z3950_client module.
273 Allow maximum number of sockets to be used for a Z39.50 client by the
274 use of SRU extra parameter x-max-sockets. This facility is handled by the
275 sru_z3950 module and the z3950_client module.
277 --- 1.0.13.1 2008/02/29
279 Simplified check for Boost libraries.
281 --- 1.0.13 2008/02/29
283 First Debian package.
285 The sru_z9350 filter now recognizes SRU parameter z-target as being
286 a ZURL of the form host/database .
288 Mergetype may be specified for filter 'multi'.
290 --- 1.0.12 2007/09/19
292 Fixed problem in Makefile WRT library specifictions. This could produce
293 linker errors (when they should not happen).
295 Fixed bug #1341: MetaProxy returning different results. Problem was that
296 fix-up of record database did not normalize the database name.
298 Documentation updates for Windows compilation.
300 --- 1.0.11 2007/06/14
302 Fixed problem with logfile being truncated.
304 --- 1.0.10 2007/05/23
306 Fixed bug #1136: Access rights not enforced.
308 Extension for log module. The log category 'access' logs more details.
309 New category 'user-access' added which is simlar to 'access' but adds
310 the Z39.50 user as for all entries in a session.
314 Added support for configurable default/force target/vhost for module Z39.50
319 Implemented filter, session_shared, which optimizes usage of Z39.50
320 sessions and result sets.
322 New filter, record_transform, which converts MARC/XML records.
324 New filter, sru_z3950, which converts SRU to Z39.50 packages.
326 New filter, load_balance, in development.
328 New filter, zeerex_xplain.
330 XML framework for config files started.
332 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
333 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
334 XML config files are checked against RNG and XML Schema's.
336 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
337 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
338 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
339 explain record to YAZ CQL-to-PQF text config file.
343 Added 'timeout' setting for filter frontend_net which specifies the number
344 of seconds a session is idle before it is closed. Default timeout is
349 Database name in records returned set for virt_db/multi filters.
351 Filter session_shared now functional.
353 Log filter can be configured to write to a given file using 'filename'
354 element. Also information category can be specified with 'category'. If
355 filename is omitted, the log filter writes to stdout. See etc/config5.xml
360 Fixed compilation on Windows.
364 Added documentation for the hidenavailable option for the multi filter.
368 Fixed bug #573: Hide errors for individual servers. If the element
369 'hideunavailable' is given in the configuration, individual servers
370 being unavailable are hidden (unless all are unavailable).
372 Fixed bug #574: Database names are recognised case-sensitively.
374 Fixed bug #567: Fix up database name in Name-Plus-Record.
376 Fixed bug #568: Update win/makefile for VS 2005.
378 Fixed bug #569: Some options throws unknown exception.
382 More information about virtual hosts. The 'etc' directory is part of the
387 Build instructions for Windows. NMake makefile part of distribution tar.
393 Filters functional: auth_simple, backend_test, frontend_net, http_file,
394 log, multi, query_rewrite, template, virt_db, z3950_client.
396 Filters in development: session_shared.
398 Pseudo-filters: template, dl
