3 http_file: only supports HTTP GET MP-523
5 session_shared: shut down expire thread in destructor
6 This ensures that expire thread is not running after destruction
7 and does bad memory references, etc.
9 frontend_net: fix segfault on startup MP-524
10 Would happen if MP was listening on multiple ports and one
11 of the ports was already in use (and MP would exit).
13 frontend_net: fix memory leak MP-521
14 This leak would occur if all sessions were in use and the input
15 queue was cleared when a client would close connection (socket).
17 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
21 http_rewrite: use local skiplist; fixes memory corruption. MP-520
23 http_client: x-forwarded-for controls X-Forwarded-For presence
24 If x-forwarded-for setting (boolean) is enabled, http_client will
25 generate an X-Forwarded-For header entry which includes existing
26 X-Forwarded-For (if any) and current peer address (immediate client
27 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
28 will not be generated.
30 z3950_client: client_ip controls client-IP presence
31 If client_ip setting (boolean) is enabled, z3950_client will
32 generate a client_ip OID as part of init request which includes
33 previous client_ip (if any) and current peer address (immediate
34 client of Metaproxy). By default client_ip is disabled and client_ip
35 will not be generated.
37 HTTP X-Forwarded-For/Z39.50 Client-IP support
38 virt_db, multi: relays Z39.50 client-IP.
39 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
40 zoom: uses Client-IP or origin address (prefer Client-IP).
41 frontend_net: Strips tcp: from peer address (so that it is no longer
42 printed and stripped in zoom filter).
43 z3950_client: builds client-IP list - combining immediate peer address
44 as returned by COMSTACK and existing client-IP list (if avaiable).
45 The Origin only printes first X-Forwarded address.
49 Log when SIG{TERM,USR1} is received ASAP MP-513
50 Do it in frontend_net event loop rather than in place for metaproxy
51 main, which only exits when all sessions are terminated for SIGUSR1
54 metaproxy-config: quote some RHS values (that might include blanks)
56 Fix leak in sru_z3950 filter - when explain is returned MP-511
58 Allow stylesheet to be given for sru_z3950 filter MP-510
59 This is based on a patch by Sven Porst and the functionality
60 of the YAZ Generic Frontend Server.
62 Allow base attribute in configuration file tags - the attributes are
63 inserted by XInclude usage as mentioned on
64 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
65 and noted in a gist: https://gist.github.com/3551094
67 Package metaproxy provides virtual package metaproxy6 MP-508
68 This allows module packages to depend on a metaproxy server
71 Filter destructors called upon daemon termination MP-505
72 When metaproxy daemon receives SIGTERM the stop method of each filter
73 is called. The stop method existed before, but did not take any
74 arguements (void).. The frontend_net filter can now distinguish
75 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
76 (stop immediately). Note that this changes the API+ABI of Metaproxy
79 zoom: sync up with Pazpar2 WRT authentication handling MP-492
81 Router: use shared_ptr rather than naked one - to avoid leak if an
82 exception is thrown in configure.
86 zoom: Add nocproxy=1 for contentConnector sessions MP-501
88 Doc: mention proper versions; fix link to Boost win binaries.
90 Windows: update for Boost 1.55
92 Windows: avoid warning when using boost::split. Done by defining
93 _SCL_SECURE_NO_WARNINGS for Visual Studio.
95 Fix LSB conformance for /etc/init.d/metaproxy MP-500
96 Debian: add support for /etc/init.d/metaproxy status
98 sort: Add const to Record less than operator in order to compile on
103 session_shared: fix element-set handling in record caching. MP-499
105 document http_rewrite. MP-468
107 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
108 respects the header (which will normally come from the cproxy filter)
112 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
113 RPM was unsable in version 1.4.0.
115 Remove log message about "backend classes". Appeared in version 1.4.0.
119 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
120 with older version from source, but packages now use YAZ 5 that supports
123 sru_z3950: Fix SEGV for decoding invalid SRU requests
124 Incorrect reference to union (was explain response rather than
127 session_shared: match additionalSearchInfo (includes facets). In
128 layman's terms means that means that facets are properly handled
129 by this filter. Eg a change in requested facets will issue new
130 search and facets from exisiting result set are cached.
132 --- 1.3.62 2013/09/11
134 http_rewrite: better handling of <script> content in HTML parser. MP-486
136 http_rewrite: fix threading issue with regex. MP-482
138 bounce: don't use strdup for fixed length content. Error occurred in echo
141 session_shared: expire backend class when no instances left. This
142 means memory clean up, but not really a leak fix.
144 virt_db: fix leak for naked ptr.
146 cql_rpn: use config relative path for cql2rpn file. MP-481
148 Updates for upcoming YAZ 5.
150 --- 1.3.61 2013/08/29
152 New configuration directories ports.d/routes.d for metaproxy
153 configuration. This allows 3rd party packages to install config
154 for ports and new routes. MP-477
156 --- 1.3.60 2013/08/21
158 Fix metaproxy-config --libs to return non-mt over mt libs.
159 The -mt versions do not exist as shared objects and cause
160 linker errors for applications linking with Metaproxy.
161 Problem present in versions 1.3.56 - 1.3.59. MP-475
163 HTML: clean up char checks. Add ptr to HTML parse spec
165 HTML parser stops eating tag when <-char is met MP-473
167 rewrite: do not even compare content types, if we don't have any
168 the regex_match caused a segfault if we had no content-type in the
171 rewrite: within header=... matches only the header value
172 Used to match the whole header line, but we need to use
173 ^$ anchoring for host-relative regexps, and they need to
174 anchor at the ends of the value. MP-470.
176 rewrite: Ruleset functional MP-469
178 --- 1.3.59 2013/07/12
180 session_shared: negotiate init sz parameters.
181 By default, session_shared will honor the paramters given by client.
182 An alternative, but not implemented, algorithm would be to only
183 re-use sessions with same sz parameters. This however, could reduce
184 re-use of sessions a lot. Hence this, simple algorithm instead. The
185 negotiation to a maximum sz values can be enabled by using
186 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
187 in configuration. This will make session_shared send those values
188 to backends and use returned init values in negotaition to
189 client before session_shared.
191 session_shared: resolve result-set references.
192 The reference is substitued with the query for old set if database
193 match and query type is Type-1. If not the reference will issue a
196 sort filter: relays RecordComposition including elementSet in use for
199 http_client: better diagnostics
201 http_client: disables HTTP redirect handling by default.
202 It can be configured with max-redirects in configuration.
204 --- 1.3.58 2013/06/12
206 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
208 --- 1.3.57 2013/06/12
210 Make RouterChain and RouterXML part of public API (libmetaproxy).
212 http_client: honor X-Metaproxy-Proxy as an alternative to
213 the "proxy" configuration. Allows proxy to be set per HTTP request.
215 sru_z3950: For SRU requests recognize x-client prefixes as a way
216 to ingest "database parameters".. The suffix of x-client- serves
217 as database argument name. Multiple may be given. For example:
218 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
219 is turned into Z39.50 database
222 --- 1.3.56 2013/05/27
224 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
226 New filter sd_remove, which replaces surrogate diagnostics with
227 SUTRS records. This filter tries to deal with clients that breaks
228 when receiving surrogate diagnostics.
230 new filter http_client. Same role as z3950_client, but just for
231 HTTP. Allows Metaproxy to operate as a HTTP proxy.
233 New filter http_rewrite1, which serves as purpose on how to rewrite
234 HTTP content with Metaproxy.
236 Use libboost-system if available, because newer versions of libboost-threads
237 requires libboost-system.
239 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
242 --- 1.3.55 2013/04/10
244 zoom: Torus setting: authenticationMode which may hold values "basic"
247 --- 1.3.54 2013/03/27
249 configure: check for Libxslt support in YAZ and rely on definitions
250 from yaz-config, rather than doing own xslt/xml2 checks.
252 Allow timestamp format for log lines to be given with option -m
253 for metaproxy. Similar to yaz-ztest/GFS option -m.
255 Document log category 'line' for log filter.
257 Solr configuration example in etc/config-solr.xml
259 multi: do not mess with request package. For scan and search,
260 database-names were modified and the request package was left with
261 dangling pointers that caused a log filter to fail (request package
262 inspected after multi was invoked).
264 Documentation: fix id of metaproxy-config ref .
266 Documentation: update for USEMARCON support.
268 --- 1.3.53 2013/01/31
270 record_transform: allow OPACXML to OPAC conversion
272 zoom: document content-proxy
274 zoom: document db parm content-{user,password}, torus_url. Also
275 <torus auth_url="..> which makes zoom operate in authenticated mode
278 --- 1.3.52 2012/11/30
280 zoom: fix http://-check. SRU search broken in 1.3.51.
282 --- 1.3.51 2012/11/15
284 zoom: only append http:// for SRU if not already given . Makes it
285 possible to use https-URLs.
287 Use yazpp 1.4 or later due to new ABI.
289 frontend_net: allow max package size to be specified. Controlled by
290 attribute 'max_recv_bytes' of element 'port'.
292 --- 1.3.50 2012/10/29
294 For most generated diagnostics by filters, typically temporary
295 system error, augment addinfo message with filter name.
297 Add support for CentOS 6 packages.
299 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
301 Add man page for metaproxy-config.
303 --- 1.3.49 2012/10/18
305 zoom: new config element passthru. This defines an element set that is
306 passed verbatim to the backend in pz2 mode.
308 auth_simple: allow both idPass and open auth. Also fix SEGV that could
311 --- 1.3.48 2012/10/08
313 z3950_client: fix string handling for init diagnostics in the case where
316 query_rewrite: no charset conversion for error queries. Avoid performing
317 charset conversion for query conversion errors. The resulting Type-1
318 query is invalid in this case.
320 --- 1.3.47 2012/10/04
322 For graceful stop (SIGUSR1), metaproxy will kill children processes.
324 Log when metaproxy is invoked in test mode (-t).
326 Log PID for each log message.
328 multi: combine both NSDs and multiple NSDs into one (diagnostics).
330 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
331 a (backend=target) is appended for each diagnostic so that can be
332 determined the origin of error.
334 multi: hideerrors also in use for present response.
336 Solr example in zoom man page.
338 Fix typo in query_rewrite config example.
340 Log at least first non surrogate diagnostic. Instead of
341 "Z_Records_multipleNSD"
343 multi: Fix check for opt Records in present response. A SEGV could occur
344 if a target did not return records and no diagnostics.
346 --- 1.3.46 2012/09/24
348 Yet another fix for graceful stop.
350 --- 1.3.45 2012/09/12
352 sru_z3950: relay surrogate diagnostics.
354 --- 1.3.44 2012/09/10
356 zoom: Honor extraArgs, strip # in zurl.
358 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
360 zoom: url_recipe allow %{var[reg]} substitutions.
361 It's like ${var[reg]} but does URI component encoding as well.
363 --- 1.3.43 2012/08/22
365 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
366 non-keepalive HTTP sessions.
368 http_file: allow zero size files (bug fix)
370 Fix zoom schema: auth_url is optional
372 --- 1.3.42 2012/08/20
374 zoom: fix un-init memory (could result in SEGV at session close)
376 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
377 and may be used in filters as usual.
379 zoom: authentication via Torus lookup
380 Enabled by new configuration setting: auth_url . If this is defined,
381 the zoom module will contact Torus for auth/IP lookup and that will
382 define realm to be used in session.
384 --- 1.3.41 2012/08/10
386 virt_db: Fix database name - first character we removed by mistake.
387 Bug introduced in 1.3.40.
389 --- 1.3.40 2012/08/06
391 virt_db: Don't use "unix path" as database for Unix sockets.
393 --- 1.3.39 2012/08/02
395 z3950_client: Don't tamper with / in zurl - fixes problems
396 using Unix sockets for backends.
398 session_shared: fix integer overflow problem with hit count.
400 session_shared: avoid long usage of cached queries.
402 zoom: New database argument , torus_url to set URL of Torus
403 record to be fetched.
405 --- 1.3.38 2012/07/04
407 Fixes for 'metaproxy reload' for RPM/Debian packages.
409 zoom: Allow rpn2cql conversion to be augmented with a properties file.
410 Element rpn2cql can be specified per-target for the zoom filter.
412 log: New category "line" which is a single-line log message with
413 most important parts of a HTTP/Z39.50 request/response.
415 --- 1.3.37 2012/06/01
417 frontend_net: add facility to report live statistics about response
418 times and current thread usage. The report is an XML document
419 and is triggered for a specific URL path. This is set by <stat-req>
420 in the configuration of frontend_net. By default this report is
421 disabled (same as empty value for <stat-req>).
423 Fix reload problem in init.d script for RPM/Debian.
424 The '/etc/init.d/metaproxy reload' in some cases would stop but not
425 start metaproxy - effectively stopping the service.
427 Don't display start log message when config testing (-t).
429 zoom: avoid CCL message limit of 1K in ZOOM filter.
431 --- 1.3.36 2012/05/10
433 metaproxy init script reacts to reload which does graceful stop +
434 start and is used by logrorate script.
436 --- 1.3.35 2012/05/09
438 Fixes for Windows compilation.
440 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
441 existing sessions running but terminate the monitor process that is
442 used in keepalive mode.
444 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
445 before. Consistent with 'metaproxy stop' message.
447 zoom: document zoom's proxy_timeout
449 z3950_client: fixup addinfo for init response
451 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
452 "Access to specified database denied" is returned, but only if init
453 response from backend does not carry diagnostics already.
455 multi: relays user info for first rejected target. The other-information
456 field for init response for first rejected target is in common init
457 response. This ensures that some backend init diagnostics are returned to
460 --- 1.3.34 2012/04/25
462 frontend_log: extend logging (when message is given in config).
464 --- 1.3.33 2012/04/25
466 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
468 --- 1.3.32 2012/04/24
470 sru_z3950 filter passes through incoming Z39.50 requests again. Was
471 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
473 --- 1.3.31 2012/04/24
475 zoom: fixes for retry/proxy failover logic. More logging.
477 --- 1.3.30 2012/04/23
479 zoom: return addinfo="proxy failure" for proxy failures. This also
480 changes the scheme for dealing with proxies a bit. zoom now always
481 do proxy check, even if there's no failover. Fortunately, that's not
484 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
485 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
486 generic. We don't know why the init would fail; IP, user, block IP, etc.
487 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
489 zoom: guess if invalid SRU response was an auth failure
491 session_shared: disable session retry by default . Can be enabled by
492 restart="true" in resultset section.
494 --- 1.3.29 2012/04/18
496 zoom: may read cf-proxy's config settings.
497 This reduces manual configuration of the content proxy server host.
498 The ZOOM module will use the old style session.proxyhost if "server"
499 is given (deprecated) and use the new style proxyhost/session if
500 "config_file" is in use.
502 frontend_net: remove incoming requests that can not be handled
503 Requests in queue for filter frontend_net are removed if client
504 closes connection for the session and request is not yet handled.
506 sru_z3950: serialize requests. This is to ensure that pipelined
507 HTTP requests are handled properly.
509 --- 1.3.28 2012/04/04
511 New class, wrbuf, that wraps YAZ' WRBUF.
513 --- 1.3.27 2012/03/30
515 Metaproxy daemon is now running as user "metaproxy". This user is
516 managed by package maintainer scripts. The user information is stored
517 in /etc/metaproxy/metaproxy.user .
519 --- 1.3.26 2012/03/20
521 New filter, sort, that allows sorting of XML records via Z39.50
524 Filter record_transform: USEMarcon support. For example:
525 <retrieval syntax="usmarc">
526 <backend syntax="unimarc" name="F">
527 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
531 Filter multi: empty route pattern uses route as default.
533 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
534 may use the shorter notation
535 <target route="z3950.indexdata.com"/>
537 Filter query_rewrite: use config path to locate XSLT.
539 Filter frontend_net: log statistics.
540 If a custom message element in frontend_net configuration it makes
541 the frontend_net filter produce a log entry whenever an operation
542 is completed. The log is always written using yaz_log with the
543 custom message given, the package ID (session ID) , the time
544 the operation has been active (end-to-end) , the threads currently
545 active/total and the size of the request input/output queues.
547 query_rewrite: charset conversion of query terms.
548 This is an optional feature. Enabled by element <charset> in
549 configuration with attribute 'from' and 'to' that specifies
550 from/to encodings. The default 'from' encoding is UTF-8.
552 Filter record_transform: honor piggyback searches.
554 Filter zoom: re-connect when database is reused.
555 Re-connect is necessary if a connection is lost or a timeout occurs.
556 If not, we'll be seeing zero hits, when we shouldn't.
558 --- 1.3.25 2012/02/29
560 zoom: Change scheme for dealing with content proxy URLs. The module
561 now has its own common XSL transform that is enabled by record_xsl
562 attribute in the configuration. This XSL gets parameter cproxyhost
563 that holds the host for the content proxy session . The genearted-url
564 is created only if urlRecipe is enabled. In previous version default
565 value of urlRecipe was ${md-electronic-url}; it is now empty and
566 disabled by default. Also generated-url no longer includes the content
567 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
570 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
571 connections. Default value is 40 (seconds).
573 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
574 "Malformed query" for syntax errors and related ones; throw
575 Bib-1: 3 "Unsupported search" for everything else. Details from
576 the CCL parser is provided as additional-info.
578 multi: new setting hideerrors that makes multi only relay diagnostics
579 to a client if all backends fail.
581 --- 1.3.24 2012/02/23
583 zoom: empty ccl_map field-mappings disables CCL map.
585 zoom: fix Explain search that could return error if session was
588 --- 1.3.23 2012/02/10
590 zoom: returns Explain records for database IR-Explain---1. The
591 target profile records are converted to Explain records via XSLT.
593 session_shared: make error recovery configurable. Whether a search
594 is restarted on errors or not, is configurable by attribute "restart"
595 in element "resultset" in configuration.
597 session_shared: only relay init for first request. session_shared, for
598 each backend class, now only relays first init request (rather than all).
599 The module only needs to save init response info once. This avoids the
600 need to check for session max.
602 --- 1.3.22 2012/02/02
604 zoom: fix memory leaks.
606 session_shared: maximum number of sessons is configurable. Default
607 value is 100. Result-sets for backends without named result sets are
608 only re-used if databases is identical for a search. This is under the
609 assumption that performance may suffer for those backends when
610 changing the database for each search.
612 multi: combines diagnostics from all backends. All diagnostics from
613 backends are combined into multiple non-surrogate diagnostics; rather
614 than just one diagnostic from first backend.
616 --- 1.3.21 2011/12/27
618 zoom: relay realm to cproxy parameter file.
620 Configuration: Allow filter collection element inside route. This
621 makes it possible to include multiple filters at once.
623 zoom: nocproxy also disables urlRecipe.
625 --- 1.3.20 2011/12/21
627 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
628 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
629 90: "Unsupported direction value".
631 zoom: honor database argument nocproxy. This disables creating a content
632 connector session (for non-CF targets, usually) and also relays nocproxy
633 as database argument to a CF target.
635 --- 1.3.19 2011/12/16
637 zoom: Multiple proxy hosts may be given for proxy rich database
638 parameter. List is comma separated.
640 http_file: decodes URI paths properly. Does not return 404: not found
641 if no prefix are matches. Instead packages are passed on.
643 --- 1.3.18 2011/12/08
645 zoom: content-{user,password,proxy} are passed on to content proxy
646 system and takes precedence over user,password,proxy .
648 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
649 with a log element including log material from children filters. At
650 this point, only the zoom filter uses this log facility. It will
651 eventually be used by other filters as well. In particular it might be
652 useful for this feature to track all filters in used during a search.
654 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
655 and queries as they are manipulated are logged.
657 zoom: extend addinfo with native diagnostics. Diagnostics as received
658 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
659 diagnostics. This indicates both a backend diagnostic and the original
662 zoom: default urlRecipe value is ${md-electronic-url}
664 zoom: target profile setting sruVersion is recognized.
666 --- 1.3.17 2011/11/17
668 zoom: log target profile record fetched (AKA Torus).
670 --- 1.3.16 2011/11/17
672 Change target profile parameter CfSubDb to CfSubDB.
674 --- 1.3.15 2011/11/12
676 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
677 makes sense to the zoom module itself).
679 --- 1.3.14 2011/11/11
681 zoom: realm may be given as part of database.
683 --- 1.3.13 2011/10/26
685 Fix Origin class assigment method; was removd by mistake in 1.3.12.
687 --- 1.3.12 2011/10/26
689 zoom: database args x-name=value are passed through to backend database.
691 SRU filter: user may specify session ID that is passed to log entries
692 that follows. It is specified by using x-session-id in the SRU arguments.
694 zoom: fix null pointer reference which would occur for bad url parameter
695 inside "torus" or if url was not given.
697 --- 1.3.11 2011/09/09
698 Fix bug in filter session_shared where sessions would not expire
699 properly (session ttl). This in turn could make the target close the
700 connection before expected and session_shared would return diagnostic
701 2: system temporarily available.
703 --- 1.3.10 2011/09/09
705 zoom: new target profile setting: sortmap_field. If sortmap_field is given
706 the field is mapped to the value for the sortmap. Values not matching
707 sortmap_field are passed verbatim.
709 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
710 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
711 depending on whether RPN or CQL is actually sent to the target.
715 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
717 zoom: For content proxy authentication is stored in param name
718 "auth", instead of "authentication".
722 zoom: relay schema in SRU mode. Previously recordSchema was not affected
727 zoom: new target profile element literalTransform that holds XSLT
728 (encoded as string) for target. Only if present and non-zero length it is
729 considered present. This takes precedence over transform.
731 Don't rely on trang anymore for Git checkout builds. Configuration in etc
732 will only be properly validated if trang is available. From now on only
733 relax NC files are bundled with the source dist.
735 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
736 component was not detected when it should be.
740 z3950_client: mark non-surrogate diagnostics from backend.
742 zoom: a proxy may be specified for HTTP fetch of target profiles.
746 Honor piggyback. Makes some SRU targets behave that insist on
747 maximumRecords > 0, but also increases performance.
751 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
752 file was not update for libdir/metaproxy4 in version 1.3.2.
756 Change location of Metaproxy modules from libdir/metaproxy to
757 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
758 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
760 New facility to dump APDUs from zoom filter. Enabled by
761 <log apdu="true"/> in the zoom filter configuation.
763 zoom filter bug fix: SRU diagnostics received from backend was
764 not properly converted to Bib-1 diagnostics.
766 Package metaproxy depends on libmetaproxy4, same version.
770 zoom: fix a bug WRT passing authentication parameters to backends.
774 Fixes for windows Makefile.
776 --- 1.2.10 2011/07/25
778 Change major version of metaproxy library from 3 to 4. This in turn
779 makes new package names for Debian and RPM.
783 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
786 zoom: configurable element sets for record transforms.
788 zoom: the target profile based transform is specified by element_transform
789 in element torus of of the ZOOM filter configuration ; default value
790 is "pz2". Target profile based retrieval is specified by element_raw
791 in configuration. It will perform same steps, but omit the XSL transform.
792 Default value is "raw".
794 zoom: element set is omitted if not set in profile. But only if pz2
795 transform is in effect. Previously the default element set was to "F".
797 zoom: For non-CF targets database arguments are parsed. User may supply
798 db,user=myuser&password=mypass for non-CF targets. These values override
799 what's given the authentication from the target profile.
801 session_shared: fix reference to freed memory. Would occur if a search
802 response had non-surrogate diagnostics.
806 Route may be given for each port in frontend_net.
810 Documentation for zoom filter. Local target profiles may be specified.
812 Fixes for zoom filter.
816 First version with zoom filter.
820 Filter z3950_client may be configured to always send a close APDU
821 to backend target when connection/session is closed. This will only
822 happen if close APDU is not already sent. Enabled by configuration
823 for z3950_client (force_close).
825 Filter virt_db and multi: relay close APDU.
827 Filter virt_db and multi: relay init size parameters
828 preferredMessageSize and maximumRecordSize.
830 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
834 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
836 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
837 as determined by configure.
839 RPM: Release includes 'indexdata' name. Use indexdata in release name so
840 this package can be distinguished from other vendors.
844 Fix filter multi: relay idAuthentication parameters.
848 Add metaproxy-config for returning compiler flags, libraries.
852 Fix --with-boost=PREFIX .
856 session_shared: fix use of maintenance thread.
858 Introduce 'start' method for filters and routers. It gets called after
859 configure and after fork, but before processing. This changes API -
860 from libmetaproxy2 to libmetaproxy3.
864 session_shared: ensure backend session is closed if init rejected
867 z3950_client: fix NULL ptr reference that could occur if two clients
868 connected concurrently and if max-sockets was in effect.
872 Fix bug 3497 - Metaproxy unstable while stopping.
874 Fix bug 3495 - SEGV in SRU filter.
878 Filter multi throws diagnostic 'Present Out of Range' when
879 appropriate - rather than returning 0 records.
881 Filter virt_db: fix bad result reuse. Could happen if a result
882 was overriden and a backend did not supported named result sets.
886 Filter log: category access logs diagnostics even if searchStatus
887 or presentStatus is 'success'.
891 The SRU to Z39.50 filter does repeated Z39.50 present requests
892 to fetch all records. Needed when a Z39.50 server returns partial
893 results (due to message size limits).
897 Metaproxy now kills all child processes that are spawned by
898 modules (in case of fork, exec).
902 Debian package now installs /etc/metaproxy/metaproxy.xml which
903 includes all XML files /etc/metaproxy/filters-enabled .
904 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
908 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
909 development package to facilitate 3rd party Metaproxy modules.
911 --- 1.0.23 2010/01/04
913 Filter virt_db: Close backend filter session when Init rejected is received
914 from it (in which case it's not really closed yet). This will ensure we don't
915 run out of resources such as FDs in this case.
917 sru_z3950 filter: Accept any database (including those not listed).
919 --- 1.0.22 2009/12/03
921 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
922 later which means YAZ 3.0.47 or later.
924 --- 1.0.20 2009/11/19
926 For filter virt_db, the database is a glob pattern and the virtual
927 database sections are consulted in the order given.
929 --- 1.0.19 2009/07/08
931 For filter multi, the target (for routing) may be given as a glob-pattern.
933 More documentation for filters virt_db and multi.
935 Update schema to allow for no database in sru_z3950 filter.
937 --- 1.0.18 2009/06/30
939 Added limit filter to put sleep (penalty) for heavy use.
941 Filter frontend_net may be configured to limit the number of new connections
942 from same IP to some value (connect-max).
944 Fixed the load_balance filter.
946 --- 1.0.17 2009/06/16
948 Fix path for metaproxy executable for Debian init.d script.
950 --- 1.0.16 2009/06/10
952 SRU to Z39.50 filter honors x-username and x-password. If only
953 x-username is given that translates to open authentication (Z39.50v2). If
954 both x-username and x-password is present that translates to idPass
955 authentication (Z39.50v3).
957 New facility to change current working directory (-w).
959 Update to upstream skeleton of init.d script. Should fix bug #2619.
961 Filter session_shared now caches records (used to only cache connections
964 Filter session_shared now invalidates a Z39.50 session if a server
965 returns -1 hits. This facility was also part of yazproxy and gets around
966 a bug in Voyager-based Z39.50 servers.
968 --- 1.0.15 2008/11/18
970 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
972 --- 1.0.14 2008/06/09
974 Fixed the value of SRU record schema in searchRetrieve response. It was set
975 to a fixed value of "dc" before.
977 Serialize identical SRU requests. This is useful if HTTP client software
978 fires identical requests against metaproxy.
980 Allow Z39.50 target to be specified for SRU requests by using SRU extra
981 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
982 avoid static configuration. This facility is handled by the sru_z3950 module
983 and the z3950_client module.
985 Allow maximum number of sockets to be used for a Z39.50 client by the
986 use of SRU extra parameter x-max-sockets. This facility is handled by the
987 sru_z3950 module and the z3950_client module.
989 --- 1.0.13.1 2008/02/29
991 Simplified check for Boost libraries.
993 --- 1.0.13 2008/02/29
995 First Debian package.
997 The sru_z9350 filter now recognizes SRU parameter z-target as being
998 a ZURL of the form host/database .
1000 Mergetype may be specified for filter 'multi'.
1002 --- 1.0.12 2007/09/19
1004 Fixed problem in Makefile WRT library specifictions. This could produce
1005 linker errors (when they should not happen).
1007 Fixed bug #1341: MetaProxy returning different results. Problem was that
1008 fix-up of record database did not normalize the database name.
1010 Documentation updates for Windows compilation.
1012 --- 1.0.11 2007/06/14
1014 Fixed problem with logfile being truncated.
1016 --- 1.0.10 2007/05/23
1018 Fixed bug #1136: Access rights not enforced.
1020 Extension for log module. The log category 'access' logs more details.
1021 New category 'user-access' added which is simlar to 'access' but adds
1022 the Z39.50 user as for all entries in a session.
1026 Added support for configurable default/force target/vhost for module Z39.50
1029 --- 1.0.8 2007/01/25
1031 Implemented filter, session_shared, which optimizes usage of Z39.50
1032 sessions and result sets.
1034 New filter, record_transform, which converts MARC/XML records.
1036 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1038 New filter, load_balance, in development.
1040 New filter, zeerex_xplain.
1042 XML framework for config files started.
1044 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1045 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1046 XML config files are checked against RNG and XML Schema's.
1048 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1049 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1050 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1051 explain record to YAZ CQL-to-PQF text config file.
1053 --- 1.0.7 2006/11/07
1055 Added 'timeout' setting for filter frontend_net which specifies the number
1056 of seconds a session is idle before it is closed. Default timeout is
1059 --- 1.0.6 2006/07/07
1061 Database name in records returned set for virt_db/multi filters.
1063 Filter session_shared now functional.
1065 Log filter can be configured to write to a given file using 'filename'
1066 element. Also information category can be specified with 'category'. If
1067 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1070 --- 1.0.5 2006/05/16
1072 Fixed compilation on Windows.
1074 --- 1.0.4 2006/05/16
1076 Added documentation for the hidenavailable option for the multi filter.
1078 --- 1.0.3 2006/05/16
1080 Fixed bug #573: Hide errors for individual servers. If the element
1081 'hideunavailable' is given in the configuration, individual servers
1082 being unavailable are hidden (unless all are unavailable).
1084 Fixed bug #574: Database names are recognised case-sensitively.
1086 Fixed bug #567: Fix up database name in Name-Plus-Record.
1088 Fixed bug #568: Update win/makefile for VS 2005.
1090 Fixed bug #569: Some options throws unknown exception.

1094 More information about virtual hosts. The 'etc' directory is part of the
1097 --- 1.0.1 2006/04/27
1099 Build instructions for Windows. NMake makefile part of distribution tar.
1101 --- 1.0.0 2006/04/24
1105 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1106 log, multi, query_rewrite, template, virt_db, z3950_client.
1108 Filters in development: session_shared.
1110 Pseudo-filters: template, dl
