3 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
4 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
5 90: "Unsupported direction value".
7 zoom: honor database argument nocproxy. This disables creating a content
8 connector session (for non-CF targets, usually) and also relays nocproxy
9 as database argument to a CF target.
13 zoom: Multiple proxy hosts may be given for proxy rich database
14 parameter. List is comma separated.
16 http_file: decodes URI paths properly. Does not return 404: not found
17 if no prefix are matches. Instead packages are passed on.
21 zoom: content-{user,password,proxy} are passed on to content proxy
22 system and takes precedence over user,password,proxy .
24 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
25 with a log element including log material from children filters. At
26 this point, only the zoom filter uses this log facility. It will
27 eventually be used by other filters as well. In particular it might be
28 useful for this feature to track all filters in used during a search.
30 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
31 and queries as they are manipulated are logged.
33 zoom: extend addinfo with native diagnostics. Diagnostics as received
34 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
35 diagnostics. This indicates both a backend diagnostic and the original
38 zoom: default urlRecipe value is ${md-electronic-url}
40 zoom: target profile setting sruVersion is recognized.
44 zoom: log target profile record fetched (AKA Torus).
48 Change target profile parameter CfSubDb to CfSubDB.
52 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
53 makes sense to the zoom module itself).
57 zoom: realm may be given as part of database.
61 Fix Origin class assigment method; was removd by mistake in 1.3.12.
65 zoom: database args x-name=value are passed through to backend database.
67 SRU filter: user may specify session ID that is passed to log entries
68 that follows. It is specified by using x-session-id in the SRU arguments.
70 zoom: fix null pointer reference which would occur for bad url parameter
71 inside "torus" or if url was not given.
74 Fix bug in filter session_shared where sessions would not expire
75 properly (session ttl). This in turn could make the target close the
76 connection before expected and session_shared would return diagnostic
77 2: system temporarily available.
81 zoom: new target profile setting: sortmap_field. If sortmap_field is given
82 the field is mapped to the value for the sortmap. Values not matching
83 sortmap_field are passed verbatim.
85 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
86 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
87 depending on whether RPN or CQL is actually sent to the target.
91 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
93 zoom: For content proxy authentication is stored in param name
94 "auth", instead of "authentication".
98 zoom: relay schema in SRU mode. Previously recordSchema was not affected
103 zoom: new target profile element literalTransform that holds XSLT
104 (encoded as string) for target. Only if present and non-zero length it is
105 considered present. This takes precedence over transform.
107 Don't rely on trang anymore for Git checkout builds. Configuration in etc
108 will only be properly validated if trang is available. From now on only
109 relax NC files are bundled with the source dist.
111 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
112 component was not detected when it should be.
116 z3950_client: mark non-surrogate diagnostics from backend.
118 zoom: a proxy may be specified for HTTP fetch of target profiles.
122 Honor piggyback. Makes some SRU targets behave that insist on
123 maximumRecords > 0, but also increases performance.
127 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
128 file was not update for libdir/metaproxy4 in version 1.3.2.
132 Change location of Metaproxy modules from libdir/metaproxy to
133 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
134 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
136 New facility to dump APDUs from zoom filter. Enabled by
137 <log apdu="true"/> in the zoom filter configuation.
139 zoom filter bug fix: SRU diagnostics received from backend was
140 not properly converted to Bib-1 diagnostics.
142 Package metaproxy depends on libmetaproxy4, same version.
146 zoom: fix a bug WRT passing authentication parameters to backends.
150 Fixes for windows Makefile.
152 --- 1.2.10 2011/07/25
154 Change major version of metaproxy library from 3 to 4. This in turn
155 makes new package names for Debian and RPM.
159 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
162 zoom: configurable element sets for record transforms.
164 zoom: the target profile based transform is specified by element_transform
165 in element torus of of the ZOOM filter configuration ; default value
166 is "pz2". Target profile based retrieval is specified by element_raw
167 in configuration. It will perform same steps, but omit the XSL transform.
168 Default value is "raw".
170 zoom: element set is omitted if not set in profile. But only if pz2
171 transform is in effect. Previously the default element set was to "F".
173 zoom: For non-CF targets database arguments are parsed. User may supply
174 db,user=myuser&password=mypass for non-CF targets. These values override
175 what's given the authentication from the target profile.
177 session_shared: fix reference to freed memory. Would occur if a search
178 response had non-surrogate diagnostics.
182 Route may be given for each port in frontend_net.
186 Documentation for zoom filter. Local target profiles may be specified.
188 Fixes for zoom filter.
192 First version with zoom filter.
196 Filter z3950_client may be configured to always send a close APDU
197 to backend target when connection/session is closed. This will only
198 happen if close APDU is not already sent. Enabled by configuration
199 for z3950_client (force_close).
201 Filter virt_db and multi: relay close APDU.
203 Filter virt_db and multi: relay init size parameters
204 preferredMessageSize and maximumRecordSize.
206 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
210 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
212 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
213 as determined by configure.
215 RPM: Release includes 'indexdata' name. Use indexdata in release name so
216 this package can be distinguished from other vendors.
220 Fix filter multi: relay idAuthentication parameters.
224 Add metaproxy-config for returning compiler flags, libraries.
228 Fix --with-boost=PREFIX .
232 session_shared: fix use of maintenance thread.
234 Introduce 'start' method for filters and routers. It gets called after
235 configure and after fork, but before processing. This changes API -
236 from libmetaproxy2 to libmetaproxy3.
240 session_shared: ensure backend session is closed if init rejected
243 z3950_client: fix NULL ptr reference that could occur if two clients
244 connected concurrently and if max-sockets was in effect.
248 Fix bug 3497 - Metaproxy unstable while stopping.
250 Fix bug 3495 - SEGV in SRU filter.
254 Filter multi throws diagnostic 'Present Out of Range' when
255 appropriate - rather than returning 0 records.
257 Filter virt_db: fix bad result reuse. Could happen if a result
258 was overriden and a backend did not supported named result sets.
262 Filter log: category access logs diagnostics even if searchStatus
263 or presentStatus is 'success'.
267 The SRU to Z39.50 filter does repeated Z39.50 present requests
268 to fetch all records. Needed when a Z39.50 server returns partial
269 results (due to message size limits).
273 Metaproxy now kills all child processes that are spawned by
274 modules (in case of fork, exec).
278 Debian package now installs /etc/metaproxy/metaproxy.xml which
279 includes all XML files /etc/metaproxy/filters-enabled .
280 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
284 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
285 development package to facilitate 3rd party Metaproxy modules.
287 --- 1.0.23 2010/01/04
289 Filter virt_db: Close backend filter session when Init rejected is received
290 from it (in which case it's not really closed yet). This will ensure we don't
291 run out of resources such as FDs in this case.
293 sru_z3950 filter: Accept any database (including those not listed).
295 --- 1.0.22 2009/12/03
297 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
298 later which means YAZ 3.0.47 or later.
300 --- 1.0.20 2009/11/19
302 For filter virt_db, the database is a glob pattern and the virtual
303 database sections are consulted in the order given.
305 --- 1.0.19 2009/07/08
307 For filter multi, the target (for routing) may be given as a glob-pattern.
309 More documentation for filters virt_db and multi.
311 Update schema to allow for no database in sru_z3950 filter.
313 --- 1.0.18 2009/06/30
315 Added limit filter to put sleep (penalty) for heavy use.
317 Filter frontend_net may be configured to limit the number of new connections
318 from same IP to some value (connect-max).
320 Fixed the load_balance filter.
322 --- 1.0.17 2009/06/16
324 Fix path for metaproxy executable for Debian init.d script.
326 --- 1.0.16 2009/06/10
328 SRU to Z39.50 filter honors x-username and x-password. If only
329 x-username is given that translates to open authentication (Z39.50v2). If
330 both x-username and x-password is present that translates to idPass
331 authentication (Z39.50v3).
333 New facility to change current working directory (-w).
335 Update to upstream skeleton of init.d script. Should fix bug #2619.
337 Filter session_shared now caches records (used to only cache connections
340 Filter session_shared now invalidates a Z39.50 session if a server
341 returns -1 hits. This facility was also part of yazproxy and gets around
342 a bug in Voyager-based Z39.50 servers.
344 --- 1.0.15 2008/11/18
346 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
348 --- 1.0.14 2008/06/09
350 Fixed the value of SRU record schema in searchRetrieve response. It was set
351 to a fixed value of "dc" before.
353 Serialize identical SRU requests. This is useful if HTTP client software
354 fires identical requests against metaproxy.
356 Allow Z39.50 target to be specified for SRU requests by using SRU extra
357 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
358 avoid static configuration. This facility is handled by the sru_z3950 module
359 and the z3950_client module.
361 Allow maximum number of sockets to be used for a Z39.50 client by the
362 use of SRU extra parameter x-max-sockets. This facility is handled by the
363 sru_z3950 module and the z3950_client module.
365 --- 1.0.13.1 2008/02/29
367 Simplified check for Boost libraries.
369 --- 1.0.13 2008/02/29
371 First Debian package.
373 The sru_z9350 filter now recognizes SRU parameter z-target as being
374 a ZURL of the form host/database .
376 Mergetype may be specified for filter 'multi'.
378 --- 1.0.12 2007/09/19
380 Fixed problem in Makefile WRT library specifictions. This could produce
381 linker errors (when they should not happen).
383 Fixed bug #1341: MetaProxy returning different results. Problem was that
384 fix-up of record database did not normalize the database name.
386 Documentation updates for Windows compilation.
388 --- 1.0.11 2007/06/14
390 Fixed problem with logfile being truncated.
392 --- 1.0.10 2007/05/23
394 Fixed bug #1136: Access rights not enforced.
396 Extension for log module. The log category 'access' logs more details.
397 New category 'user-access' added which is simlar to 'access' but adds
398 the Z39.50 user as for all entries in a session.
402 Added support for configurable default/force target/vhost for module Z39.50
407 Implemented filter, session_shared, which optimizes usage of Z39.50
408 sessions and result sets.
410 New filter, record_transform, which converts MARC/XML records.
412 New filter, sru_z3950, which converts SRU to Z39.50 packages.
414 New filter, load_balance, in development.
416 New filter, zeerex_xplain.
418 XML framework for config files started.
420 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
421 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
422 XML config files are checked against RNG and XML Schema's.
424 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
425 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
426 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
427 explain record to YAZ CQL-to-PQF text config file.
431 Added 'timeout' setting for filter frontend_net which specifies the number
432 of seconds a session is idle before it is closed. Default timeout is
437 Database name in records returned set for virt_db/multi filters.
439 Filter session_shared now functional.
441 Log filter can be configured to write to a given file using 'filename'
442 element. Also information category can be specified with 'category'. If
443 filename is omitted, the log filter writes to stdout. See etc/config5.xml
448 Fixed compilation on Windows.
452 Added documentation for the hidenavailable option for the multi filter.
456 Fixed bug #573: Hide errors for individual servers. If the element
457 'hideunavailable' is given in the configuration, individual servers
458 being unavailable are hidden (unless all are unavailable).
460 Fixed bug #574: Database names are recognised case-sensitively.
462 Fixed bug #567: Fix up database name in Name-Plus-Record.
464 Fixed bug #568: Update win/makefile for VS 2005.
466 Fixed bug #569: Some options throws unknown exception.
470 More information about virtual hosts. The 'etc' directory is part of the
475 Build instructions for Windows. NMake makefile part of distribution tar.
481 Filters functional: auth_simple, backend_test, frontend_net, http_file,
482 log, multi, query_rewrite, template, virt_db, z3950_client.
484 Filters in development: session_shared.
486 Pseudo-filters: template, dl
