3 zoom: new target profile element literalTransform that holds XSLT
4 (encoded as string) for target. Only if present and non-zero length it is
5 considered present. This takes precedence over transform.
7 Don't rely on trang anymore for Git checkout builds. Configuration in etc
8 will only be properly validated if trang is available. From now on only
9 relax NC files are bundled with the source dist.
11 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
12 component was not detected when it should be.
16 z3950_client: mark non-surrogate diagnostics from backend.
18 zoom: a proxy may be specified for HTTP fetch of target profiles.
22 Honor piggyback. Makes some SRU targets behave that insist on
23 maximumRecords > 0, but also increases performance.
27 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
28 file was not update for libdir/metaproxy4 in version 1.3.2.
32 Change location of Metaproxy modules from libdir/metaproxy to
33 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
34 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
36 New facility to dump APDUs from zoom filter. Enabled by
37 <log apdu="true"/> in the zoom filter configuation.
39 zoom filter bug fix: SRU diagnostics received from backend was
40 not properly converted to Bib-1 diagnostics.
42 Package metaproxy depends on libmetaproxy4, same version.
46 zoom: fix a bug WRT passing authentication parameters to backends.
50 Fixes for windows Makefile.
54 Change major version of metaproxy library from 3 to 4. This in turn
55 makes new package names for Debian and RPM.
59 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
62 zoom: configurable element sets for record transforms.
64 zoom: the target profile based transform is specified by element_transform
65 in element torus of of the ZOOM filter configuration ; default value
66 is "pz2". Target profile based retrieval is specified by element_raw
67 in configuration. It will perform same steps, but omit the XSL transform.
68 Default value is "raw".
70 zoom: element set is omitted if not set in profile. But only if pz2
71 transform is in effect. Previously the default element set was to "F".
73 zoom: For non-CF targets database arguments are parsed. User may supply
74 db,user=myuser&password=mypass for non-CF targets. These values override
75 what's given the authentication from the target profile.
77 session_shared: fix reference to freed memory. Would occur if a search
78 response had non-surrogate diagnostics.
82 Route may be given for each port in frontend_net.
86 Documentation for zoom filter. Local target profiles may be specified.
88 Fixes for zoom filter.
92 First version with zoom filter.
96 Filter z3950_client may be configured to always send a close APDU
97 to backend target when connection/session is closed. This will only
98 happen if close APDU is not already sent. Enabled by configuration
99 for z3950_client (force_close).
101 Filter virt_db and multi: relay close APDU.
103 Filter virt_db and multi: relay init size parameters
104 preferredMessageSize and maximumRecordSize.
106 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
110 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
112 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
113 as determined by configure.
115 RPM: Release includes 'indexdata' name. Use indexdata in release name so
116 this package can be distinguished from other vendors.
120 Fix filter multi: relay idAuthentication parameters.
124 Add metaproxy-config for returning compiler flags, libraries.
128 Fix --with-boost=PREFIX .
132 session_shared: fix use of maintenance thread.
134 Introduce 'start' method for filters and routers. It gets called after
135 configure and after fork, but before processing. This changes API -
136 from libmetaproxy2 to libmetaproxy3.
140 session_shared: ensure backend session is closed if init rejected
143 z3950_client: fix NULL ptr reference that could occur if two clients
144 connected concurrently and if max-sockets was in effect.
148 Fix bug 3497 - Metaproxy unstable while stopping.
150 Fix bug 3495 - SEGV in SRU filter.
154 Filter multi throws diagnostic 'Present Out of Range' when
155 appropriate - rather than returning 0 records.
157 Filter virt_db: fix bad result reuse. Could happen if a result
158 was overriden and a backend did not supported named result sets.
162 Filter log: category access logs diagnostics even if searchStatus
163 or presentStatus is 'success'.
167 The SRU to Z39.50 filter does repeated Z39.50 present requests
168 to fetch all records. Needed when a Z39.50 server returns partial
169 results (due to message size limits).
173 Metaproxy now kills all child processes that are spawned by
174 modules (in case of fork, exec).
178 Debian package now installs /etc/metaproxy/metaproxy.xml which
179 includes all XML files /etc/metaproxy/filters-enabled .
180 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
184 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
185 development package to facilitate 3rd party Metaproxy modules.
187 --- 1.0.23 2010/01/04
189 Filter virt_db: Close backend filter session when Init rejected is received
190 from it (in which case it's not really closed yet). This will ensure we don't
191 run out of resources such as FDs in this case.
193 sru_z3950 filter: Accept any database (including those not listed).
195 --- 1.0.22 2009/12/03
197 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
198 later which means YAZ 3.0.47 or later.
200 --- 1.0.20 2009/11/19
202 For filter virt_db, the database is a glob pattern and the virtual
203 database sections are consulted in the order given.
205 --- 1.0.19 2009/07/08
207 For filter multi, the target (for routing) may be given as a glob-pattern.
209 More documentation for filters virt_db and multi.
211 Update schema to allow for no database in sru_z3950 filter.
213 --- 1.0.18 2009/06/30
215 Added limit filter to put sleep (penalty) for heavy use.
217 Filter frontend_net may be configured to limit the number of new connections
218 from same IP to some value (connect-max).
220 Fixed the load_balance filter.
222 --- 1.0.17 2009/06/16
224 Fix path for metaproxy executable for Debian init.d script.
226 --- 1.0.16 2009/06/10
228 SRU to Z39.50 filter honors x-username and x-password. If only
229 x-username is given that translates to open authentication (Z39.50v2). If
230 both x-username and x-password is present that translates to idPass
231 authentication (Z39.50v3).
233 New facility to change current working directory (-w).
235 Update to upstream skeleton of init.d script. Should fix bug #2619.
237 Filter session_shared now caches records (used to only cache connections
240 Filter session_shared now invalidates a Z39.50 session if a server
241 returns -1 hits. This facility was also part of yazproxy and gets around
242 a bug in Voyager-based Z39.50 servers.
244 --- 1.0.15 2008/11/18
246 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
248 --- 1.0.14 2008/06/09
250 Fixed the value of SRU record schema in searchRetrieve response. It was set
251 to a fixed value of "dc" before.
253 Serialize identical SRU requests. This is useful if HTTP client software
254 fires identical requests against metaproxy.
256 Allow Z39.50 target to be specified for SRU requests by using SRU extra
257 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
258 avoid static configuration. This facility is handled by the sru_z3950 module
259 and the z3950_client module.
261 Allow maximum number of sockets to be used for a Z39.50 client by the
262 use of SRU extra parameter x-max-sockets. This facility is handled by the
263 sru_z3950 module and the z3950_client module.
265 --- 1.0.13.1 2008/02/29
267 Simplified check for Boost libraries.
269 --- 1.0.13 2008/02/29
271 First Debian package.
273 The sru_z9350 filter now recognizes SRU parameter z-target as being
274 a ZURL of the form host/database .
276 Mergetype may be specified for filter 'multi'.
278 --- 1.0.12 2007/09/19
280 Fixed problem in Makefile WRT library specifictions. This could produce
281 linker errors (when they should not happen).
283 Fixed bug #1341: MetaProxy returning different results. Problem was that
284 fix-up of record database did not normalize the database name.
286 Documentation updates for Windows compilation.
288 --- 1.0.11 2007/06/14
290 Fixed problem with logfile being truncated.
292 --- 1.0.10 2007/05/23
294 Fixed bug #1136: Access rights not enforced.
296 Extension for log module. The log category 'access' logs more details.
297 New category 'user-access' added which is simlar to 'access' but adds
298 the Z39.50 user as for all entries in a session.
302 Added support for configurable default/force target/vhost for module Z39.50
307 Implemented filter, session_shared, which optimizes usage of Z39.50
308 sessions and result sets.
310 New filter, record_transform, which converts MARC/XML records.
312 New filter, sru_z3950, which converts SRU to Z39.50 packages.
314 New filter, load_balance, in development.
316 New filter, zeerex_xplain.
318 XML framework for config files started.
320 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
321 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
322 XML config files are checked against RNG and XML Schema's.
324 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
325 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
326 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
327 explain record to YAZ CQL-to-PQF text config file.
331 Added 'timeout' setting for filter frontend_net which specifies the number
332 of seconds a session is idle before it is closed. Default timeout is
337 Database name in records returned set for virt_db/multi filters.
339 Filter session_shared now functional.
341 Log filter can be configured to write to a given file using 'filename'
342 element. Also information category can be specified with 'category'. If
343 filename is omitted, the log filter writes to stdout. See etc/config5.xml
348 Fixed compilation on Windows.
352 Added documentation for the hidenavailable option for the multi filter.
356 Fixed bug #573: Hide errors for individual servers. If the element
357 'hideunavailable' is given in the configuration, individual servers
358 being unavailable are hidden (unless all are unavailable).
360 Fixed bug #574: Database names are recognised case-sensitively.
362 Fixed bug #567: Fix up database name in Name-Plus-Record.
364 Fixed bug #568: Update win/makefile for VS 2005.
366 Fixed bug #569: Some options throws unknown exception.
370 More information about virtual hosts. The 'etc' directory is part of the
375 Build instructions for Windows. NMake makefile part of distribution tar.
381 Filters functional: auth_simple, backend_test, frontend_net, http_file,
382 log, multi, query_rewrite, template, virt_db, z3950_client.
384 Filters in development: session_shared.
