3 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
4 file was not update for libdir/metaproxy4 in version 1.3.2.
8 Change location of Metaproxy modules from libdir/metaproxy to
9 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
10 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
12 New facility to dump APDUs from zoom filter. Enabled by
13 <log apdu="true"/> in the zoom filter configuation.
15 zoom filter bug fix: SRU diagnostics received from backend was
16 not properly converted to Bib-1 diagnostics.
18 Package metaproxy depends on libmetaproxy4, same version.
22 zoom: fix a bug WRT passing authentication parameters to backends.
26 Fixes for windows Makefile.
30 Change major version of metaproxy library from 3 to 4. This in turn
31 makes new package names for Debian and RPM.
35 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
38 zoom: configurable element sets for record transforms.
40 zoom: the target profile based transform is specified by element_transform
41 in element torus of of the ZOOM filter configuration ; default value
42 is "pz2". Target profile based retrieval is specified by element_raw
43 in configuration. It will perform same steps, but omit the XSL transform.
44 Default value is "raw".
46 zoom: element set is omitted if not set in profile. But only if pz2
47 transform is in effect. Previously the default element set was to "F".
49 zoom: For non-CF targets database arguments are parsed. User may supply
50 db,user=myuser&password=mypass for non-CF targets. These values override
51 what's given the authentication from the target profile.
53 session_shared: fix reference to freed memory. Would occur if a search
54 response had non-surrogate diagnostics.
58 Route may be given for each port in frontend_net.
62 Documentation for zoom filter. Local target profiles may be specified.
64 Fixes for zoom filter.
68 First version with zoom filter.
72 Filter z3950_client may be configured to always send a close APDU
73 to backend target when connection/session is closed. This will only
74 happen if close APDU is not already sent. Enabled by configuration
75 for z3950_client (force_close).
77 Filter virt_db and multi: relay close APDU.
79 Filter virt_db and multi: relay init size parameters
80 preferredMessageSize and maximumRecordSize.
82 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
86 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
88 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
89 as determined by configure.
91 RPM: Release includes 'indexdata' name. Use indexdata in release name so
92 this package can be distinguished from other vendors.
96 Fix filter multi: relay idAuthentication parameters.
100 Add metaproxy-config for returning compiler flags, libraries.
104 Fix --with-boost=PREFIX .
108 session_shared: fix use of maintenance thread.
110 Introduce 'start' method for filters and routers. It gets called after
111 configure and after fork, but before processing. This changes API -
112 from libmetaproxy2 to libmetaproxy3.
116 session_shared: ensure backend session is closed if init rejected
119 z3950_client: fix NULL ptr reference that could occur if two clients
120 connected concurrently and if max-sockets was in effect.
124 Fix bug 3497 - Metaproxy unstable while stopping.
126 Fix bug 3495 - SEGV in SRU filter.
130 Filter multi throws diagnostic 'Present Out of Range' when
131 appropriate - rather than returning 0 records.
133 Filter virt_db: fix bad result reuse. Could happen if a result
134 was overriden and a backend did not supported named result sets.
138 Filter log: category access logs diagnostics even if searchStatus
139 or presentStatus is 'success'.
143 The SRU to Z39.50 filter does repeated Z39.50 present requests
144 to fetch all records. Needed when a Z39.50 server returns partial
145 results (due to message size limits).
149 Metaproxy now kills all child processes that are spawned by
150 modules (in case of fork, exec).
154 Debian package now installs /etc/metaproxy/metaproxy.xml which
155 includes all XML files /etc/metaproxy/filters-enabled .
156 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
160 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
161 development package to facilitate 3rd party Metaproxy modules.
163 --- 1.0.23 2010/01/04
165 Filter virt_db: Close backend filter session when Init rejected is received
166 from it (in which case it's not really closed yet). This will ensure we don't
167 run out of resources such as FDs in this case.
169 sru_z3950 filter: Accept any database (including those not listed).
171 --- 1.0.22 2009/12/03
173 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
174 later which means YAZ 3.0.47 or later.
176 --- 1.0.20 2009/11/19
178 For filter virt_db, the database is a glob pattern and the virtual
179 database sections are consulted in the order given.
181 --- 1.0.19 2009/07/08
183 For filter multi, the target (for routing) may be given as a glob-pattern.
185 More documentation for filters virt_db and multi.
187 Update schema to allow for no database in sru_z3950 filter.
189 --- 1.0.18 2009/06/30
191 Added limit filter to put sleep (penalty) for heavy use.
193 Filter frontend_net may be configured to limit the number of new connections
194 from same IP to some value (connect-max).
196 Fixed the load_balance filter.
198 --- 1.0.17 2009/06/16
200 Fix path for metaproxy executable for Debian init.d script.
202 --- 1.0.16 2009/06/10
204 SRU to Z39.50 filter honors x-username and x-password. If only
205 x-username is given that translates to open authentication (Z39.50v2). If
206 both x-username and x-password is present that translates to idPass
207 authentication (Z39.50v3).
209 New facility to change current working directory (-w).
211 Update to upstream skeleton of init.d script. Should fix bug #2619.
213 Filter session_shared now caches records (used to only cache connections
216 Filter session_shared now invalidates a Z39.50 session if a server
217 returns -1 hits. This facility was also part of yazproxy and gets around
218 a bug in Voyager-based Z39.50 servers.
220 --- 1.0.15 2008/11/18
222 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
224 --- 1.0.14 2008/06/09
226 Fixed the value of SRU record schema in searchRetrieve response. It was set
227 to a fixed value of "dc" before.
229 Serialize identical SRU requests. This is useful if HTTP client software
230 fires identical requests against metaproxy.
232 Allow Z39.50 target to be specified for SRU requests by using SRU extra
233 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
234 avoid static configuration. This facility is handled by the sru_z3950 module
235 and the z3950_client module.
237 Allow maximum number of sockets to be used for a Z39.50 client by the
238 use of SRU extra parameter x-max-sockets. This facility is handled by the
239 sru_z3950 module and the z3950_client module.
241 --- 1.0.13.1 2008/02/29
243 Simplified check for Boost libraries.
245 --- 1.0.13 2008/02/29
247 First Debian package.
249 The sru_z9350 filter now recognizes SRU parameter z-target as being
250 a ZURL of the form host/database .
252 Mergetype may be specified for filter 'multi'.
254 --- 1.0.12 2007/09/19
256 Fixed problem in Makefile WRT library specifictions. This could produce
257 linker errors (when they should not happen).
259 Fixed bug #1341: MetaProxy returning different results. Problem was that
260 fix-up of record database did not normalize the database name.
262 Documentation updates for Windows compilation.
264 --- 1.0.11 2007/06/14
266 Fixed problem with logfile being truncated.
268 --- 1.0.10 2007/05/23
270 Fixed bug #1136: Access rights not enforced.
272 Extension for log module. The log category 'access' logs more details.
273 New category 'user-access' added which is simlar to 'access' but adds
274 the Z39.50 user as for all entries in a session.
278 Added support for configurable default/force target/vhost for module Z39.50
283 Implemented filter, session_shared, which optimizes usage of Z39.50
284 sessions and result sets.
286 New filter, record_transform, which converts MARC/XML records.
288 New filter, sru_z3950, which converts SRU to Z39.50 packages.
290 New filter, load_balance, in development.
292 New filter, zeerex_xplain.
294 XML framework for config files started.
296 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
297 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
298 XML config files are checked against RNG and XML Schema's.
300 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
301 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
302 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
303 explain record to YAZ CQL-to-PQF text config file.
307 Added 'timeout' setting for filter frontend_net which specifies the number
308 of seconds a session is idle before it is closed. Default timeout is
313 Database name in records returned set for virt_db/multi filters.
315 Filter session_shared now functional.
317 Log filter can be configured to write to a given file using 'filename'
318 element. Also information category can be specified with 'category'. If
319 filename is omitted, the log filter writes to stdout. See etc/config5.xml
324 Fixed compilation on Windows.
328 Added documentation for the hidenavailable option for the multi filter.
332 Fixed bug #573: Hide errors for individual servers. If the element
333 'hideunavailable' is given in the configuration, individual servers
334 being unavailable are hidden (unless all are unavailable).
336 Fixed bug #574: Database names are recognised case-sensitively.
338 Fixed bug #567: Fix up database name in Name-Plus-Record.
340 Fixed bug #568: Update win/makefile for VS 2005.
342 Fixed bug #569: Some options throws unknown exception.
346 More information about virtual hosts. The 'etc' directory is part of the
351 Build instructions for Windows. NMake makefile part of distribution tar.
357 Filters functional: auth_simple, backend_test, frontend_net, http_file,
358 log, multi, query_rewrite, template, virt_db, z3950_client.
360 Filters in development: session_shared.
