3 http_rewrite: use local skiplist; fixes memory corruption. MP-520
5 http_client: x-forwarded-for controls X-Forwarded-For presence
6 If x-forwarded-for setting (boolean) is enabled, http_client will
7 generate an X-Forwarded-For header entry which includes existing
8 X-Forwarded-For (if any) and current peer address (immediate client
9 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
10 will not be generated.
12 z3950_client: client_ip controls client-IP presence
13 If client_ip setting (boolean) is enabled, z3950_client will
14 generate a client_ip OID as part of init request which includes
15 previous client_ip (if any) and current peer address (immediate
16 client of Metaproxy). By default client_ip is disabled and client_ip
17 will not be generated.
19 HTTP X-Forwarded-For/Z39.50 Client-IP support
20 virt_db, multi: relays Z39.50 client-IP.
21 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
22 zoom: uses Client-IP or origin address (prefer Client-IP).
23 frontend_net: Strips tcp: from peer address (so that it is no longer
24 printed and stripped in zoom filter).
25 z3950_client: builds client-IP list - combining immediate peer address
26 as returned by COMSTACK and existing client-IP list (if avaiable).
27 The Origin only printes first X-Forwarded address.
31 Log when SIG{TERM,USR1} is received ASAP MP-513
32 Do it in frontend_net event loop rather than in place for metaproxy
33 main, which only exits when all sessions are terminated for SIGUSR1
36 metaproxy-config: quote some RHS values (that might include blanks)
38 Fix leak in sru_z3950 filter - when explain is returned MP-511
40 Allow stylesheet to be given for sru_z3950 filter MP-510
41 This is based on a patch by Sven Porst and the functionality
42 of the YAZ Generic Frontend Server.
44 Allow base attribute in configuration file tags - the attributes are
45 inserted by XInclude usage as mentioned on
46 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
47 and noted in a gist: https://gist.github.com/3551094
49 Package metaproxy provides virtual package metaproxy6 MP-508
50 This allows module packages to depend on a metaproxy server
53 Filter destructors called upon daemon termination MP-505
54 When metaproxy daemon receives SIGTERM the stop method of each filter
55 is called. The stop method existed before, but did not take any
56 arguements (void).. The frontend_net filter can now distinguish
57 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
58 (stop immediately). Note that this changes the API+ABI of Metaproxy
61 zoom: sync up with Pazpar2 WRT authentication handling MP-492
63 Router: use shared_ptr rather than naked one - to avoid leak if an
64 exception is thrown in configure.
68 zoom: Add nocproxy=1 for contentConnector sessions MP-501
70 Doc: mention proper versions; fix link to Boost win binaries.
72 Windows: update for Boost 1.55
74 Windows: avoid warning when using boost::split. Done by defining
75 _SCL_SECURE_NO_WARNINGS for Visual Studio.
77 Fix LSB conformance for /etc/init.d/metaproxy MP-500
78 Debian: add support for /etc/init.d/metaproxy status
80 sort: Add const to Record less than operator in order to compile on
85 session_shared: fix element-set handling in record caching. MP-499
87 document http_rewrite. MP-468
89 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
90 respects the header (which will normally come from the cproxy filter)
94 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
95 RPM was unsable in version 1.4.0.
97 Remove log message about "backend classes". Appeared in version 1.4.0.
101 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
102 with older version from source, but packages now use YAZ 5 that supports
105 sru_z3950: Fix SEGV for decoding invalid SRU requests
106 Incorrect reference to union (was explain response rather than
109 session_shared: match additionalSearchInfo (includes facets). In
110 layman's terms means that means that facets are properly handled
111 by this filter. Eg a change in requested facets will issue new
112 search and facets from exisiting result set are cached.
114 --- 1.3.62 2013/09/11
116 http_rewrite: better handling of <script> content in HTML parser. MP-486
118 http_rewrite: fix threading issue with regex. MP-482
120 bounce: don't use strdup for fixed length content. Error occurred in echo
123 session_shared: expire backend class when no instances left. This
124 means memory clean up, but not really a leak fix.
126 virt_db: fix leak for naked ptr.
128 cql_rpn: use config relative path for cql2rpn file. MP-481
130 Updates for upcoming YAZ 5.
132 --- 1.3.61 2013/08/29
134 New configuration directories ports.d/routes.d for metaproxy
135 configuration. This allows 3rd party packages to install config
136 for ports and new routes. MP-477
138 --- 1.3.60 2013/08/21
140 Fix metaproxy-config --libs to return non-mt over mt libs.
141 The -mt versions do not exist as shared objects and cause
142 linker errors for applications linking with Metaproxy.
143 Problem present in versions 1.3.56 - 1.3.59. MP-475
145 HTML: clean up char checks. Add ptr to HTML parse spec
147 HTML parser stops eating tag when <-char is met MP-473
149 rewrite: do not even compare content types, if we don't have any
150 the regex_match caused a segfault if we had no content-type in the
153 rewrite: within header=... matches only the header value
154 Used to match the whole header line, but we need to use
155 ^$ anchoring for host-relative regexps, and they need to
156 anchor at the ends of the value. MP-470.
158 rewrite: Ruleset functional MP-469
160 --- 1.3.59 2013/07/12
162 session_shared: negotiate init sz parameters.
163 By default, session_shared will honor the paramters given by client.
164 An alternative, but not implemented, algorithm would be to only
165 re-use sessions with same sz parameters. This however, could reduce
166 re-use of sessions a lot. Hence this, simple algorithm instead. The
167 negotiation to a maximum sz values can be enabled by using
168 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
169 in configuration. This will make session_shared send those values
170 to backends and use returned init values in negotaition to
171 client before session_shared.
173 session_shared: resolve result-set references.
174 The reference is substitued with the query for old set if database
175 match and query type is Type-1. If not the reference will issue a
178 sort filter: relays RecordComposition including elementSet in use for
181 http_client: better diagnostics
183 http_client: disables HTTP redirect handling by default.
184 It can be configured with max-redirects in configuration.
186 --- 1.3.58 2013/06/12
188 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
190 --- 1.3.57 2013/06/12
192 Make RouterChain and RouterXML part of public API (libmetaproxy).
194 http_client: honor X-Metaproxy-Proxy as an alternative to
195 the "proxy" configuration. Allows proxy to be set per HTTP request.
197 sru_z3950: For SRU requests recognize x-client prefixes as a way
198 to ingest "database parameters".. The suffix of x-client- serves
199 as database argument name. Multiple may be given. For example:
200 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
201 is turned into Z39.50 database
204 --- 1.3.56 2013/05/27
206 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
208 New filter sd_remove, which replaces surrogate diagnostics with
209 SUTRS records. This filter tries to deal with clients that breaks
210 when receiving surrogate diagnostics.
212 new filter http_client. Same role as z3950_client, but just for
213 HTTP. Allows Metaproxy to operate as a HTTP proxy.
215 New filter http_rewrite1, which serves as purpose on how to rewrite
216 HTTP content with Metaproxy.
218 Use libboost-system if available, because newer versions of libboost-threads
219 requires libboost-system.
221 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
224 --- 1.3.55 2013/04/10
226 zoom: Torus setting: authenticationMode which may hold values "basic"
229 --- 1.3.54 2013/03/27
231 configure: check for Libxslt support in YAZ and rely on definitions
232 from yaz-config, rather than doing own xslt/xml2 checks.
234 Allow timestamp format for log lines to be given with option -m
235 for metaproxy. Similar to yaz-ztest/GFS option -m.
237 Document log category 'line' for log filter.
239 Solr configuration example in etc/config-solr.xml
241 multi: do not mess with request package. For scan and search,
242 database-names were modified and the request package was left with
243 dangling pointers that caused a log filter to fail (request package
244 inspected after multi was invoked).
246 Documentation: fix id of metaproxy-config ref .
248 Documentation: update for USEMARCON support.
250 --- 1.3.53 2013/01/31
252 record_transform: allow OPACXML to OPAC conversion
254 zoom: document content-proxy
256 zoom: document db parm content-{user,password}, torus_url. Also
257 <torus auth_url="..> which makes zoom operate in authenticated mode
260 --- 1.3.52 2012/11/30
262 zoom: fix http://-check. SRU search broken in 1.3.51.
264 --- 1.3.51 2012/11/15
266 zoom: only append http:// for SRU if not already given . Makes it
267 possible to use https-URLs.
269 Use yazpp 1.4 or later due to new ABI.
271 frontend_net: allow max package size to be specified. Controlled by
272 attribute 'max_recv_bytes' of element 'port'.
274 --- 1.3.50 2012/10/29
276 For most generated diagnostics by filters, typically temporary
277 system error, augment addinfo message with filter name.
279 Add support for CentOS 6 packages.
281 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
283 Add man page for metaproxy-config.
285 --- 1.3.49 2012/10/18
287 zoom: new config element passthru. This defines an element set that is
288 passed verbatim to the backend in pz2 mode.
290 auth_simple: allow both idPass and open auth. Also fix SEGV that could
293 --- 1.3.48 2012/10/08
295 z3950_client: fix string handling for init diagnostics in the case where
298 query_rewrite: no charset conversion for error queries. Avoid performing
299 charset conversion for query conversion errors. The resulting Type-1
300 query is invalid in this case.
302 --- 1.3.47 2012/10/04
304 For graceful stop (SIGUSR1), metaproxy will kill children processes.
306 Log when metaproxy is invoked in test mode (-t).
308 Log PID for each log message.
310 multi: combine both NSDs and multiple NSDs into one (diagnostics).
312 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
313 a (backend=target) is appended for each diagnostic so that can be
314 determined the origin of error.
316 multi: hideerrors also in use for present response.
318 Solr example in zoom man page.
320 Fix typo in query_rewrite config example.
322 Log at least first non surrogate diagnostic. Instead of
323 "Z_Records_multipleNSD"
325 multi: Fix check for opt Records in present response. A SEGV could occur
326 if a target did not return records and no diagnostics.
328 --- 1.3.46 2012/09/24
330 Yet another fix for graceful stop.
332 --- 1.3.45 2012/09/12
334 sru_z3950: relay surrogate diagnostics.
336 --- 1.3.44 2012/09/10
338 zoom: Honor extraArgs, strip # in zurl.
340 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
342 zoom: url_recipe allow %{var[reg]} substitutions.
343 It's like ${var[reg]} but does URI component encoding as well.
345 --- 1.3.43 2012/08/22
347 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
348 non-keepalive HTTP sessions.
350 http_file: allow zero size files (bug fix)
352 Fix zoom schema: auth_url is optional
354 --- 1.3.42 2012/08/20
356 zoom: fix un-init memory (could result in SEGV at session close)
358 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
359 and may be used in filters as usual.
361 zoom: authentication via Torus lookup
362 Enabled by new configuration setting: auth_url . If this is defined,
363 the zoom module will contact Torus for auth/IP lookup and that will
364 define realm to be used in session.
366 --- 1.3.41 2012/08/10
368 virt_db: Fix database name - first character we removed by mistake.
369 Bug introduced in 1.3.40.
371 --- 1.3.40 2012/08/06
373 virt_db: Don't use "unix path" as database for Unix sockets.
375 --- 1.3.39 2012/08/02
377 z3950_client: Don't tamper with / in zurl - fixes problems
378 using Unix sockets for backends.
380 session_shared: fix integer overflow problem with hit count.
382 session_shared: avoid long usage of cached queries.
384 zoom: New database argument , torus_url to set URL of Torus
385 record to be fetched.
387 --- 1.3.38 2012/07/04
389 Fixes for 'metaproxy reload' for RPM/Debian packages.
391 zoom: Allow rpn2cql conversion to be augmented with a properties file.
392 Element rpn2cql can be specified per-target for the zoom filter.
394 log: New category "line" which is a single-line log message with
395 most important parts of a HTTP/Z39.50 request/response.
397 --- 1.3.37 2012/06/01
399 frontend_net: add facility to report live statistics about response
400 times and current thread usage. The report is an XML document
401 and is triggered for a specific URL path. This is set by <stat-req>
402 in the configuration of frontend_net. By default this report is
403 disabled (same as empty value for <stat-req>).
405 Fix reload problem in init.d script for RPM/Debian.
406 The '/etc/init.d/metaproxy reload' in some cases would stop but not
407 start metaproxy - effectively stopping the service.
409 Don't display start log message when config testing (-t).
411 zoom: avoid CCL message limit of 1K in ZOOM filter.
413 --- 1.3.36 2012/05/10
415 metaproxy init script reacts to reload which does graceful stop +
416 start and is used by logrorate script.
418 --- 1.3.35 2012/05/09
420 Fixes for Windows compilation.
422 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
423 existing sessions running but terminate the monitor process that is
424 used in keepalive mode.
426 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
427 before. Consistent with 'metaproxy stop' message.
429 zoom: document zoom's proxy_timeout
431 z3950_client: fixup addinfo for init response
433 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
434 "Access to specified database denied" is returned, but only if init
435 response from backend does not carry diagnostics already.
437 multi: relays user info for first rejected target. The other-information
438 field for init response for first rejected target is in common init
439 response. This ensures that some backend init diagnostics are returned to
442 --- 1.3.34 2012/04/25
444 frontend_log: extend logging (when message is given in config).
446 --- 1.3.33 2012/04/25
448 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
450 --- 1.3.32 2012/04/24
452 sru_z3950 filter passes through incoming Z39.50 requests again. Was
453 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
455 --- 1.3.31 2012/04/24
457 zoom: fixes for retry/proxy failover logic. More logging.
459 --- 1.3.30 2012/04/23
461 zoom: return addinfo="proxy failure" for proxy failures. This also
462 changes the scheme for dealing with proxies a bit. zoom now always
463 do proxy check, even if there's no failover. Fortunately, that's not
466 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
467 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
468 generic. We don't know why the init would fail; IP, user, block IP, etc.
469 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
471 zoom: guess if invalid SRU response was an auth failure
473 session_shared: disable session retry by default . Can be enabled by
474 restart="true" in resultset section.
476 --- 1.3.29 2012/04/18
478 zoom: may read cf-proxy's config settings.
479 This reduces manual configuration of the content proxy server host.
480 The ZOOM module will use the old style session.proxyhost if "server"
481 is given (deprecated) and use the new style proxyhost/session if
482 "config_file" is in use.
484 frontend_net: remove incoming requests that can not be handled
485 Requests in queue for filter frontend_net are removed if client
486 closes connection for the session and request is not yet handled.
488 sru_z3950: serialize requests. This is to ensure that pipelined
489 HTTP requests are handled properly.
491 --- 1.3.28 2012/04/04
493 New class, wrbuf, that wraps YAZ' WRBUF.
495 --- 1.3.27 2012/03/30
497 Metaproxy daemon is now running as user "metaproxy". This user is
498 managed by package maintainer scripts. The user information is stored
499 in /etc/metaproxy/metaproxy.user .
501 --- 1.3.26 2012/03/20
503 New filter, sort, that allows sorting of XML records via Z39.50
506 Filter record_transform: USEMarcon support. For example:
507 <retrieval syntax="usmarc">
508 <backend syntax="unimarc" name="F">
509 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
513 Filter multi: empty route pattern uses route as default.
515 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
516 may use the shorter notation
517 <target route="z3950.indexdata.com"/>
519 Filter query_rewrite: use config path to locate XSLT.
521 Filter frontend_net: log statistics.
522 If a custom message element in frontend_net configuration it makes
523 the frontend_net filter produce a log entry whenever an operation
524 is completed. The log is always written using yaz_log with the
525 custom message given, the package ID (session ID) , the time
526 the operation has been active (end-to-end) , the threads currently
527 active/total and the size of the request input/output queues.
529 query_rewrite: charset conversion of query terms.
530 This is an optional feature. Enabled by element <charset> in
531 configuration with attribute 'from' and 'to' that specifies
532 from/to encodings. The default 'from' encoding is UTF-8.
534 Filter record_transform: honor piggyback searches.
536 Filter zoom: re-connect when database is reused.
537 Re-connect is necessary if a connection is lost or a timeout occurs.
538 If not, we'll be seeing zero hits, when we shouldn't.
540 --- 1.3.25 2012/02/29
542 zoom: Change scheme for dealing with content proxy URLs. The module
543 now has its own common XSL transform that is enabled by record_xsl
544 attribute in the configuration. This XSL gets parameter cproxyhost
545 that holds the host for the content proxy session . The genearted-url
546 is created only if urlRecipe is enabled. In previous version default
547 value of urlRecipe was ${md-electronic-url}; it is now empty and
548 disabled by default. Also generated-url no longer includes the content
549 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
552 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
553 connections. Default value is 40 (seconds).
555 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
556 "Malformed query" for syntax errors and related ones; throw
557 Bib-1: 3 "Unsupported search" for everything else. Details from
558 the CCL parser is provided as additional-info.
560 multi: new setting hideerrors that makes multi only relay diagnostics
561 to a client if all backends fail.
563 --- 1.3.24 2012/02/23
565 zoom: empty ccl_map field-mappings disables CCL map.
567 zoom: fix Explain search that could return error if session was
570 --- 1.3.23 2012/02/10
572 zoom: returns Explain records for database IR-Explain---1. The
573 target profile records are converted to Explain records via XSLT.
575 session_shared: make error recovery configurable. Whether a search
576 is restarted on errors or not, is configurable by attribute "restart"
577 in element "resultset" in configuration.
579 session_shared: only relay init for first request. session_shared, for
580 each backend class, now only relays first init request (rather than all).
581 The module only needs to save init response info once. This avoids the
582 need to check for session max.
584 --- 1.3.22 2012/02/02
586 zoom: fix memory leaks.
588 session_shared: maximum number of sessons is configurable. Default
589 value is 100. Result-sets for backends without named result sets are
590 only re-used if databases is identical for a search. This is under the
591 assumption that performance may suffer for those backends when
592 changing the database for each search.
594 multi: combines diagnostics from all backends. All diagnostics from
595 backends are combined into multiple non-surrogate diagnostics; rather
596 than just one diagnostic from first backend.
598 --- 1.3.21 2011/12/27
600 zoom: relay realm to cproxy parameter file.
602 Configuration: Allow filter collection element inside route. This
603 makes it possible to include multiple filters at once.
605 zoom: nocproxy also disables urlRecipe.
607 --- 1.3.20 2011/12/21
609 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
610 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
611 90: "Unsupported direction value".
613 zoom: honor database argument nocproxy. This disables creating a content
614 connector session (for non-CF targets, usually) and also relays nocproxy
615 as database argument to a CF target.
617 --- 1.3.19 2011/12/16
619 zoom: Multiple proxy hosts may be given for proxy rich database
620 parameter. List is comma separated.
622 http_file: decodes URI paths properly. Does not return 404: not found
623 if no prefix are matches. Instead packages are passed on.
625 --- 1.3.18 2011/12/08
627 zoom: content-{user,password,proxy} are passed on to content proxy
628 system and takes precedence over user,password,proxy .
630 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
631 with a log element including log material from children filters. At
632 this point, only the zoom filter uses this log facility. It will
633 eventually be used by other filters as well. In particular it might be
634 useful for this feature to track all filters in used during a search.
636 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
637 and queries as they are manipulated are logged.
639 zoom: extend addinfo with native diagnostics. Diagnostics as received
640 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
641 diagnostics. This indicates both a backend diagnostic and the original
644 zoom: default urlRecipe value is ${md-electronic-url}
646 zoom: target profile setting sruVersion is recognized.
648 --- 1.3.17 2011/11/17
650 zoom: log target profile record fetched (AKA Torus).
652 --- 1.3.16 2011/11/17
654 Change target profile parameter CfSubDb to CfSubDB.
656 --- 1.3.15 2011/11/12
658 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
659 makes sense to the zoom module itself).
661 --- 1.3.14 2011/11/11
663 zoom: realm may be given as part of database.
665 --- 1.3.13 2011/10/26
667 Fix Origin class assigment method; was removd by mistake in 1.3.12.
669 --- 1.3.12 2011/10/26
671 zoom: database args x-name=value are passed through to backend database.
673 SRU filter: user may specify session ID that is passed to log entries
674 that follows. It is specified by using x-session-id in the SRU arguments.
676 zoom: fix null pointer reference which would occur for bad url parameter
677 inside "torus" or if url was not given.
679 --- 1.3.11 2011/09/09
680 Fix bug in filter session_shared where sessions would not expire
681 properly (session ttl). This in turn could make the target close the
682 connection before expected and session_shared would return diagnostic
683 2: system temporarily available.
685 --- 1.3.10 2011/09/09
687 zoom: new target profile setting: sortmap_field. If sortmap_field is given
688 the field is mapped to the value for the sortmap. Values not matching
689 sortmap_field are passed verbatim.
691 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
692 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
693 depending on whether RPN or CQL is actually sent to the target.
697 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
699 zoom: For content proxy authentication is stored in param name
700 "auth", instead of "authentication".
704 zoom: relay schema in SRU mode. Previously recordSchema was not affected
709 zoom: new target profile element literalTransform that holds XSLT
710 (encoded as string) for target. Only if present and non-zero length it is
711 considered present. This takes precedence over transform.
713 Don't rely on trang anymore for Git checkout builds. Configuration in etc
714 will only be properly validated if trang is available. From now on only
715 relax NC files are bundled with the source dist.
717 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
718 component was not detected when it should be.
722 z3950_client: mark non-surrogate diagnostics from backend.
724 zoom: a proxy may be specified for HTTP fetch of target profiles.
728 Honor piggyback. Makes some SRU targets behave that insist on
729 maximumRecords > 0, but also increases performance.
733 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
734 file was not update for libdir/metaproxy4 in version 1.3.2.
738 Change location of Metaproxy modules from libdir/metaproxy to
739 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
740 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
742 New facility to dump APDUs from zoom filter. Enabled by
743 <log apdu="true"/> in the zoom filter configuation.
745 zoom filter bug fix: SRU diagnostics received from backend was
746 not properly converted to Bib-1 diagnostics.
748 Package metaproxy depends on libmetaproxy4, same version.
752 zoom: fix a bug WRT passing authentication parameters to backends.
756 Fixes for windows Makefile.
758 --- 1.2.10 2011/07/25
760 Change major version of metaproxy library from 3 to 4. This in turn
761 makes new package names for Debian and RPM.
765 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
768 zoom: configurable element sets for record transforms.
770 zoom: the target profile based transform is specified by element_transform
771 in element torus of of the ZOOM filter configuration ; default value
772 is "pz2". Target profile based retrieval is specified by element_raw
773 in configuration. It will perform same steps, but omit the XSL transform.
774 Default value is "raw".
776 zoom: element set is omitted if not set in profile. But only if pz2
777 transform is in effect. Previously the default element set was to "F".
779 zoom: For non-CF targets database arguments are parsed. User may supply
780 db,user=myuser&password=mypass for non-CF targets. These values override
781 what's given the authentication from the target profile.
783 session_shared: fix reference to freed memory. Would occur if a search
784 response had non-surrogate diagnostics.
788 Route may be given for each port in frontend_net.
792 Documentation for zoom filter. Local target profiles may be specified.
794 Fixes for zoom filter.
798 First version with zoom filter.
802 Filter z3950_client may be configured to always send a close APDU
803 to backend target when connection/session is closed. This will only
804 happen if close APDU is not already sent. Enabled by configuration
805 for z3950_client (force_close).
807 Filter virt_db and multi: relay close APDU.
809 Filter virt_db and multi: relay init size parameters
810 preferredMessageSize and maximumRecordSize.
812 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
816 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
818 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
819 as determined by configure.
821 RPM: Release includes 'indexdata' name. Use indexdata in release name so
822 this package can be distinguished from other vendors.
826 Fix filter multi: relay idAuthentication parameters.
830 Add metaproxy-config for returning compiler flags, libraries.
834 Fix --with-boost=PREFIX .
838 session_shared: fix use of maintenance thread.
840 Introduce 'start' method for filters and routers. It gets called after
841 configure and after fork, but before processing. This changes API -
842 from libmetaproxy2 to libmetaproxy3.
846 session_shared: ensure backend session is closed if init rejected
849 z3950_client: fix NULL ptr reference that could occur if two clients
850 connected concurrently and if max-sockets was in effect.
854 Fix bug 3497 - Metaproxy unstable while stopping.
856 Fix bug 3495 - SEGV in SRU filter.
860 Filter multi throws diagnostic 'Present Out of Range' when
861 appropriate - rather than returning 0 records.
863 Filter virt_db: fix bad result reuse. Could happen if a result
864 was overriden and a backend did not supported named result sets.
868 Filter log: category access logs diagnostics even if searchStatus
869 or presentStatus is 'success'.
873 The SRU to Z39.50 filter does repeated Z39.50 present requests
874 to fetch all records. Needed when a Z39.50 server returns partial
875 results (due to message size limits).
879 Metaproxy now kills all child processes that are spawned by
880 modules (in case of fork, exec).
884 Debian package now installs /etc/metaproxy/metaproxy.xml which
885 includes all XML files /etc/metaproxy/filters-enabled .
886 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
890 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
891 development package to facilitate 3rd party Metaproxy modules.
893 --- 1.0.23 2010/01/04
895 Filter virt_db: Close backend filter session when Init rejected is received
896 from it (in which case it's not really closed yet). This will ensure we don't
897 run out of resources such as FDs in this case.
899 sru_z3950 filter: Accept any database (including those not listed).
901 --- 1.0.22 2009/12/03
903 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
904 later which means YAZ 3.0.47 or later.
906 --- 1.0.20 2009/11/19
908 For filter virt_db, the database is a glob pattern and the virtual
909 database sections are consulted in the order given.
911 --- 1.0.19 2009/07/08
913 For filter multi, the target (for routing) may be given as a glob-pattern.
915 More documentation for filters virt_db and multi.
917 Update schema to allow for no database in sru_z3950 filter.
919 --- 1.0.18 2009/06/30
921 Added limit filter to put sleep (penalty) for heavy use.
923 Filter frontend_net may be configured to limit the number of new connections
924 from same IP to some value (connect-max).
926 Fixed the load_balance filter.
928 --- 1.0.17 2009/06/16
930 Fix path for metaproxy executable for Debian init.d script.
932 --- 1.0.16 2009/06/10
934 SRU to Z39.50 filter honors x-username and x-password. If only
935 x-username is given that translates to open authentication (Z39.50v2). If
936 both x-username and x-password is present that translates to idPass
937 authentication (Z39.50v3).
939 New facility to change current working directory (-w).
941 Update to upstream skeleton of init.d script. Should fix bug #2619.
943 Filter session_shared now caches records (used to only cache connections
946 Filter session_shared now invalidates a Z39.50 session if a server
947 returns -1 hits. This facility was also part of yazproxy and gets around
948 a bug in Voyager-based Z39.50 servers.
950 --- 1.0.15 2008/11/18
952 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
954 --- 1.0.14 2008/06/09
956 Fixed the value of SRU record schema in searchRetrieve response. It was set
957 to a fixed value of "dc" before.
959 Serialize identical SRU requests. This is useful if HTTP client software
960 fires identical requests against metaproxy.
962 Allow Z39.50 target to be specified for SRU requests by using SRU extra
963 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
964 avoid static configuration. This facility is handled by the sru_z3950 module
965 and the z3950_client module.
967 Allow maximum number of sockets to be used for a Z39.50 client by the
968 use of SRU extra parameter x-max-sockets. This facility is handled by the
969 sru_z3950 module and the z3950_client module.
971 --- 1.0.13.1 2008/02/29
973 Simplified check for Boost libraries.
975 --- 1.0.13 2008/02/29
977 First Debian package.
979 The sru_z9350 filter now recognizes SRU parameter z-target as being
980 a ZURL of the form host/database .
982 Mergetype may be specified for filter 'multi'.
984 --- 1.0.12 2007/09/19
986 Fixed problem in Makefile WRT library specifictions. This could produce
987 linker errors (when they should not happen).
989 Fixed bug #1341: MetaProxy returning different results. Problem was that
990 fix-up of record database did not normalize the database name.
992 Documentation updates for Windows compilation.
994 --- 1.0.11 2007/06/14
996 Fixed problem with logfile being truncated.
998 --- 1.0.10 2007/05/23
1000 Fixed bug #1136: Access rights not enforced.
1002 Extension for log module. The log category 'access' logs more details.
1003 New category 'user-access' added which is simlar to 'access' but adds
1004 the Z39.50 user as for all entries in a session.
1008 Added support for configurable default/force target/vhost for module Z39.50
1011 --- 1.0.8 2007/01/25
1013 Implemented filter, session_shared, which optimizes usage of Z39.50
1014 sessions and result sets.
1016 New filter, record_transform, which converts MARC/XML records.
1018 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1020 New filter, load_balance, in development.
1022 New filter, zeerex_xplain.
1024 XML framework for config files started.
1026 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1027 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1028 XML config files are checked against RNG and XML Schema's.
1030 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1031 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1032 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1033 explain record to YAZ CQL-to-PQF text config file.
1035 --- 1.0.7 2006/11/07
1037 Added 'timeout' setting for filter frontend_net which specifies the number
1038 of seconds a session is idle before it is closed. Default timeout is
1041 --- 1.0.6 2006/07/07
1043 Database name in records returned set for virt_db/multi filters.
1045 Filter session_shared now functional.
1047 Log filter can be configured to write to a given file using 'filename'
1048 element. Also information category can be specified with 'category'. If
1049 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1052 --- 1.0.5 2006/05/16
1054 Fixed compilation on Windows.
1056 --- 1.0.4 2006/05/16
1058 Added documentation for the hidenavailable option for the multi filter.
1060 --- 1.0.3 2006/05/16
1062 Fixed bug #573: Hide errors for individual servers. If the element
1063 'hideunavailable' is given in the configuration, individual servers
1064 being unavailable are hidden (unless all are unavailable).
1066 Fixed bug #574: Database names are recognised case-sensitively.
1068 Fixed bug #567: Fix up database name in Name-Plus-Record.
1070 Fixed bug #568: Update win/makefile for VS 2005.
1072 Fixed bug #569: Some options throws unknown exception.

1076 More information about virtual hosts. The 'etc' directory is part of the
1079 --- 1.0.1 2006/04/27
1081 Build instructions for Windows. NMake makefile part of distribution tar.
1083 --- 1.0.0 2006/04/24
1087 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1088 log, multi, query_rewrite, template, virt_db, z3950_client.
1090 Filters in development: session_shared.
