3 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
6 zoom: configurable element sets for record transforms.
8 zoom: the target profile based transform is specified by element_transform
9 in element torus of of the ZOOM filter configuration ; default value
10 is "pz2". Target profile based retrieval is specified by element_raw
11 in configuration. It will perform same steps, but omit the XSL transform.
12 Default value is "raw".
14 zoom: element set is omitted if not set in profile. But only if pz2
15 transform is in effect. Previously the default element set was to "F".
17 zoom: For non-CF targets database arguments are parsed. User may supply
18 db,user=myuser&password=mypass for non-CF targets. These values override
19 what's given the authentication from the target profile.
21 session_shared: fix reference to freed memory. Would occur if a search
22 response had non-surrogate diagnostics.
26 Route may be given for each port in frontend_net.
30 Documentation for zoom filter. Local target profiles may be specified.
32 Fixes for zoom filter.
36 First version with zoom filter.
40 Filter z3950_client may be configured to always send a close APDU
41 to backend target when connection/session is closed. This will only
42 happen if close APDU is not already sent. Enabled by configuration
43 for z3950_client (force_close).
45 Filter virt_db and multi: relay close APDU.
47 Filter virt_db and multi: relay init size parameters
48 preferredMessageSize and maximumRecordSize.
50 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
54 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
56 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
57 as determined by configure.
59 RPM: Release includes 'indexdata' name. Use indexdata in release name so
60 this package can be distinguished from other vendors.
64 Fix filter multi: relay idAuthentication parameters.
68 Add metaproxy-config for returning compiler flags, libraries.
72 Fix --with-boost=PREFIX .
76 session_shared: fix use of maintenance thread.
78 Introduce 'start' method for filters and routers. It gets called after
79 configure and after fork, but before processing. This changes API -
80 from libmetaproxy2 to libmetaproxy3.
84 session_shared: ensure backend session is closed if init rejected
87 z3950_client: fix NULL ptr reference that could occur if two clients
88 connected concurrently and if max-sockets was in effect.
92 Fix bug 3497 - Metaproxy unstable while stopping.
94 Fix bug 3495 - SEGV in SRU filter.
98 Filter multi throws diagnostic 'Present Out of Range' when
99 appropriate - rather than returning 0 records.
101 Filter virt_db: fix bad result reuse. Could happen if a result
102 was overriden and a backend did not supported named result sets.
106 Filter log: category access logs diagnostics even if searchStatus
107 or presentStatus is 'success'.
111 The SRU to Z39.50 filter does repeated Z39.50 present requests
112 to fetch all records. Needed when a Z39.50 server returns partial
113 results (due to message size limits).
117 Metaproxy now kills all child processes that are spawned by
118 modules (in case of fork, exec).
122 Debian package now installs /etc/metaproxy/metaproxy.xml which
123 includes all XML files /etc/metaproxy/filters-enabled .
124 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
128 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
129 development package to facilitate 3rd party Metaproxy modules.
131 --- 1.0.23 2010/01/04
133 Filter virt_db: Close backend filter session when Init rejected is received
134 from it (in which case it's not really closed yet). This will ensure we don't
135 run out of resources such as FDs in this case.
137 sru_z3950 filter: Accept any database (including those not listed).
139 --- 1.0.22 2009/12/03
141 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
142 later which means YAZ 3.0.47 or later.
144 --- 1.0.20 2009/11/19
146 For filter virt_db, the database is a glob pattern and the virtual
147 database sections are consulted in the order given.
149 --- 1.0.19 2009/07/08
151 For filter multi, the target (for routing) may be given as a glob-pattern.
153 More documentation for filters virt_db and multi.
155 Update schema to allow for no database in sru_z3950 filter.
157 --- 1.0.18 2009/06/30
159 Added limit filter to put sleep (penalty) for heavy use.
161 Filter frontend_net may be configured to limit the number of new connections
162 from same IP to some value (connect-max).
164 Fixed the load_balance filter.
166 --- 1.0.17 2009/06/16
168 Fix path for metaproxy executable for Debian init.d script.
170 --- 1.0.16 2009/06/10
172 SRU to Z39.50 filter honors x-username and x-password. If only
173 x-username is given that translates to open authentication (Z39.50v2). If
174 both x-username and x-password is present that translates to idPass
175 authentication (Z39.50v3).
177 New facility to change current working directory (-w).
179 Update to upstream skeleton of init.d script. Should fix bug #2619.
181 Filter session_shared now caches records (used to only cache connections
184 Filter session_shared now invalidates a Z39.50 session if a server
185 returns -1 hits. This facility was also part of yazproxy and gets around
186 a bug in Voyager-based Z39.50 servers.
188 --- 1.0.15 2008/11/18
190 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
192 --- 1.0.14 2008/06/09
194 Fixed the value of SRU record schema in searchRetrieve response. It was set
195 to a fixed value of "dc" before.
197 Serialize identical SRU requests. This is useful if HTTP client software
198 fires identical requests against metaproxy.
200 Allow Z39.50 target to be specified for SRU requests by using SRU extra
201 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
202 avoid static configuration. This facility is handled by the sru_z3950 module
203 and the z3950_client module.
205 Allow maximum number of sockets to be used for a Z39.50 client by the
206 use of SRU extra parameter x-max-sockets. This facility is handled by the
207 sru_z3950 module and the z3950_client module.
209 --- 1.0.13.1 2008/02/29
211 Simplified check for Boost libraries.
213 --- 1.0.13 2008/02/29
215 First Debian package.
217 The sru_z9350 filter now recognizes SRU parameter z-target as being
218 a ZURL of the form host/database .
220 Mergetype may be specified for filter 'multi'.
222 --- 1.0.12 2007/09/19
224 Fixed problem in Makefile WRT library specifictions. This could produce
225 linker errors (when they should not happen).
227 Fixed bug #1341: MetaProxy returning different results. Problem was that
228 fix-up of record database did not normalize the database name.
230 Documentation updates for Windows compilation.
232 --- 1.0.11 2007/06/14
234 Fixed problem with logfile being truncated.
236 --- 1.0.10 2007/05/23
238 Fixed bug #1136: Access rights not enforced.
240 Extension for log module. The log category 'access' logs more details.
241 New category 'user-access' added which is simlar to 'access' but adds
242 the Z39.50 user as for all entries in a session.
246 Added support for configurable default/force target/vhost for module Z39.50
251 Implemented filter, session_shared, which optimizes usage of Z39.50
252 sessions and result sets.
254 New filter, record_transform, which converts MARC/XML records.
256 New filter, sru_z3950, which converts SRU to Z39.50 packages.
258 New filter, load_balance, in development.
260 New filter, zeerex_xplain.
262 XML framework for config files started.
264 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
265 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
266 XML config files are checked against RNG and XML Schema's.
268 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
269 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
270 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
271 explain record to YAZ CQL-to-PQF text config file.
275 Added 'timeout' setting for filter frontend_net which specifies the number
276 of seconds a session is idle before it is closed. Default timeout is
281 Database name in records returned set for virt_db/multi filters.
283 Filter session_shared now functional.
285 Log filter can be configured to write to a given file using 'filename'
286 element. Also information category can be specified with 'category'. If
287 filename is omitted, the log filter writes to stdout. See etc/config5.xml
292 Fixed compilation on Windows.
296 Added documentation for the hidenavailable option for the multi filter.
300 Fixed bug #573: Hide errors for individual servers. If the element
301 'hideunavailable' is given in the configuration, individual servers
302 being unavailable are hidden (unless all are unavailable).
304 Fixed bug #574: Database names are recognised case-sensitively.
306 Fixed bug #567: Fix up database name in Name-Plus-Record.
308 Fixed bug #568: Update win/makefile for VS 2005.
310 Fixed bug #569: Some options throws unknown exception.
314 More information about virtual hosts. The 'etc' directory is part of the
319 Build instructions for Windows. NMake makefile part of distribution tar.
325 Filters functional: auth_simple, backend_test, frontend_net, http_file,
326 log, multi, query_rewrite, template, virt_db, z3950_client.
328 Filters in development: session_shared.
