1 Change major version of metaproxy library from 3 to 4. This in turn
2 makes new package names for Debian and RPM.
6 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
9 zoom: configurable element sets for record transforms.
11 zoom: the target profile based transform is specified by element_transform
12 in element torus of of the ZOOM filter configuration ; default value
13 is "pz2". Target profile based retrieval is specified by element_raw
14 in configuration. It will perform same steps, but omit the XSL transform.
15 Default value is "raw".
17 zoom: element set is omitted if not set in profile. But only if pz2
18 transform is in effect. Previously the default element set was to "F".
20 zoom: For non-CF targets database arguments are parsed. User may supply
21 db,user=myuser&password=mypass for non-CF targets. These values override
22 what's given the authentication from the target profile.
24 session_shared: fix reference to freed memory. Would occur if a search
25 response had non-surrogate diagnostics.
29 Route may be given for each port in frontend_net.
33 Documentation for zoom filter. Local target profiles may be specified.
35 Fixes for zoom filter.
39 First version with zoom filter.
43 Filter z3950_client may be configured to always send a close APDU
44 to backend target when connection/session is closed. This will only
45 happen if close APDU is not already sent. Enabled by configuration
46 for z3950_client (force_close).
48 Filter virt_db and multi: relay close APDU.
50 Filter virt_db and multi: relay init size parameters
51 preferredMessageSize and maximumRecordSize.
53 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
57 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
59 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
60 as determined by configure.
62 RPM: Release includes 'indexdata' name. Use indexdata in release name so
63 this package can be distinguished from other vendors.
67 Fix filter multi: relay idAuthentication parameters.
71 Add metaproxy-config for returning compiler flags, libraries.
75 Fix --with-boost=PREFIX .
79 session_shared: fix use of maintenance thread.
81 Introduce 'start' method for filters and routers. It gets called after
82 configure and after fork, but before processing. This changes API -
83 from libmetaproxy2 to libmetaproxy3.
87 session_shared: ensure backend session is closed if init rejected
90 z3950_client: fix NULL ptr reference that could occur if two clients
91 connected concurrently and if max-sockets was in effect.
95 Fix bug 3497 - Metaproxy unstable while stopping.
97 Fix bug 3495 - SEGV in SRU filter.
101 Filter multi throws diagnostic 'Present Out of Range' when
102 appropriate - rather than returning 0 records.
104 Filter virt_db: fix bad result reuse. Could happen if a result
105 was overriden and a backend did not supported named result sets.
109 Filter log: category access logs diagnostics even if searchStatus
110 or presentStatus is 'success'.
114 The SRU to Z39.50 filter does repeated Z39.50 present requests
115 to fetch all records. Needed when a Z39.50 server returns partial
116 results (due to message size limits).
120 Metaproxy now kills all child processes that are spawned by
121 modules (in case of fork, exec).
125 Debian package now installs /etc/metaproxy/metaproxy.xml which
126 includes all XML files /etc/metaproxy/filters-enabled .
127 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
131 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
132 development package to facilitate 3rd party Metaproxy modules.
134 --- 1.0.23 2010/01/04
136 Filter virt_db: Close backend filter session when Init rejected is received
137 from it (in which case it's not really closed yet). This will ensure we don't
138 run out of resources such as FDs in this case.
140 sru_z3950 filter: Accept any database (including those not listed).
142 --- 1.0.22 2009/12/03
144 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
145 later which means YAZ 3.0.47 or later.
147 --- 1.0.20 2009/11/19
149 For filter virt_db, the database is a glob pattern and the virtual
150 database sections are consulted in the order given.
152 --- 1.0.19 2009/07/08
154 For filter multi, the target (for routing) may be given as a glob-pattern.
156 More documentation for filters virt_db and multi.
158 Update schema to allow for no database in sru_z3950 filter.
160 --- 1.0.18 2009/06/30
162 Added limit filter to put sleep (penalty) for heavy use.
164 Filter frontend_net may be configured to limit the number of new connections
165 from same IP to some value (connect-max).
167 Fixed the load_balance filter.
169 --- 1.0.17 2009/06/16
171 Fix path for metaproxy executable for Debian init.d script.
173 --- 1.0.16 2009/06/10
175 SRU to Z39.50 filter honors x-username and x-password. If only
176 x-username is given that translates to open authentication (Z39.50v2). If
177 both x-username and x-password is present that translates to idPass
178 authentication (Z39.50v3).
180 New facility to change current working directory (-w).
182 Update to upstream skeleton of init.d script. Should fix bug #2619.
184 Filter session_shared now caches records (used to only cache connections
187 Filter session_shared now invalidates a Z39.50 session if a server
188 returns -1 hits. This facility was also part of yazproxy and gets around
189 a bug in Voyager-based Z39.50 servers.
191 --- 1.0.15 2008/11/18
193 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
195 --- 1.0.14 2008/06/09
197 Fixed the value of SRU record schema in searchRetrieve response. It was set
198 to a fixed value of "dc" before.
200 Serialize identical SRU requests. This is useful if HTTP client software
201 fires identical requests against metaproxy.
203 Allow Z39.50 target to be specified for SRU requests by using SRU extra
204 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
205 avoid static configuration. This facility is handled by the sru_z3950 module
206 and the z3950_client module.
208 Allow maximum number of sockets to be used for a Z39.50 client by the
209 use of SRU extra parameter x-max-sockets. This facility is handled by the
210 sru_z3950 module and the z3950_client module.
212 --- 1.0.13.1 2008/02/29
214 Simplified check for Boost libraries.
216 --- 1.0.13 2008/02/29
218 First Debian package.
220 The sru_z9350 filter now recognizes SRU parameter z-target as being
221 a ZURL of the form host/database .
223 Mergetype may be specified for filter 'multi'.
225 --- 1.0.12 2007/09/19
227 Fixed problem in Makefile WRT library specifictions. This could produce
228 linker errors (when they should not happen).
230 Fixed bug #1341: MetaProxy returning different results. Problem was that
231 fix-up of record database did not normalize the database name.
233 Documentation updates for Windows compilation.
235 --- 1.0.11 2007/06/14
237 Fixed problem with logfile being truncated.
239 --- 1.0.10 2007/05/23
241 Fixed bug #1136: Access rights not enforced.
243 Extension for log module. The log category 'access' logs more details.
244 New category 'user-access' added which is simlar to 'access' but adds
245 the Z39.50 user as for all entries in a session.
249 Added support for configurable default/force target/vhost for module Z39.50
254 Implemented filter, session_shared, which optimizes usage of Z39.50
255 sessions and result sets.
257 New filter, record_transform, which converts MARC/XML records.
259 New filter, sru_z3950, which converts SRU to Z39.50 packages.
261 New filter, load_balance, in development.
263 New filter, zeerex_xplain.
265 XML framework for config files started.
267 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
268 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
269 XML config files are checked against RNG and XML Schema's.
271 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
272 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
273 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
274 explain record to YAZ CQL-to-PQF text config file.
278 Added 'timeout' setting for filter frontend_net which specifies the number
279 of seconds a session is idle before it is closed. Default timeout is
284 Database name in records returned set for virt_db/multi filters.
286 Filter session_shared now functional.
288 Log filter can be configured to write to a given file using 'filename'
289 element. Also information category can be specified with 'category'. If
290 filename is omitted, the log filter writes to stdout. See etc/config5.xml
295 Fixed compilation on Windows.
299 Added documentation for the hidenavailable option for the multi filter.
303 Fixed bug #573: Hide errors for individual servers. If the element
304 'hideunavailable' is given in the configuration, individual servers
305 being unavailable are hidden (unless all are unavailable).
307 Fixed bug #574: Database names are recognised case-sensitively.
309 Fixed bug #567: Fix up database name in Name-Plus-Record.
311 Fixed bug #568: Update win/makefile for VS 2005.
313 Fixed bug #569: Some options throws unknown exception.
317 More information about virtual hosts. The 'etc' directory is part of the
322 Build instructions for Windows. NMake makefile part of distribution tar.
328 Filters functional: auth_simple, backend_test, frontend_net, http_file,
329 log, multi, query_rewrite, template, virt_db, z3950_client.
331 Filters in development: session_shared.
333 Pseudo-filters: template, dl
