30 Fix systemd: reload stops metaproxy MP-620
31 Detect systemd and just do nothing when reload/force-reload is
32 used. Log, however, that it really is not reloading.
34 Add http-req-max to frontend_net MP-617
38 Fix multi: hideunavailable don't hide target that timeout MP-615
42 Fix race condition in MP log output MP-522
44 Fix 'Group' is duplicated twice in RPM spec
46 Fix crash in log filter when record syntax is omitted MP-613
48 Change target z3950.loc.gov:7090/voyager -> lx2.loc.gov:210/LCDB_MARC8
51 Fix Control-C does not stop Metaproxy spawned by shell MP-610
52 Check for fork mode instead (-D) - rather than debug (-X)
56 sru_z3950: allow CCL in SRU search MP-606
57 Makes the sru_z3950 filter convert to CCL queries if query type
58 "ccl" is used, eg ?query=water&queryType=ccl&... for SRU 2.0.
62 Fix dead lock in session_shared (init) MP-605
66 Fix session_shared caches set with diagnostic MP-604
68 Fix assertion failed in session_shared filter MP-603
70 Make /usr/share/metaproxy be part of metaproxy RPM MP-601
72 Log YAZ version upon start MP-599
76 sru_z3950: undo Serialize identical SRU GET requests MP-598
77 Now much more elegantly handled by session_shared.
79 session_shared: anticipated init and search MP-597
81 z3950_client: separate init timeout MP-596
82 Both init-timeout and connect-timeout are configurable by this change.
83 Default is 10 seconds.
87 zoom: support cf_-params MP-595
89 http_client: returns 404 if no destination URI is given
93 zoom: allow / in user and password db args MP-592
97 Log rotate no longer reloads configuration - instead Metaproxy just
98 re-opens log files when SIGHUP is received. MP-485
100 Debian : init.d metaproxy reload should check configuration MP-591
102 Fix Metaproxy stops logging after check config failed MP-590
106 Fix double free in log filter (with incorrect config) MP-589
108 zoom: Add allow_ip feature - fixes MP-588
109 Allow a list of IPs to be given separated by blanks
110 <allow auth_url="http://mkc-admin.indexdata.com/..."
111 allow_ip="127.0.0.1 ::1" .. >

143 Add support for binding outgoing IP for http_client and z3950_client
144 This is enabled by bind_host setting. MP-575
148 z3950_client: allows negotiation charset to be set MP-574
150 cgi: more functional but no support for POSTed content yet (part of MP-564)
152 --- 1.5.11 2014/10/20
154 http_file: add include of sys/stat.h fixes MP-576
156 Fix documentation about SRU client support MP-572
158 Initialize Libxml2 - for threaded operation MP-571
160 --- 1.5.10 2014/08/26
162 On SIGTERM shut down connection+listening sockets MP-568
163 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
167 zoom: make retry on failure configurable MP-565
168 The default and existing behavior is that backend failures (any
169 diagnostic) makes the module re-search once. The behavior may
170 be changed by db parameter 'retry'. If given value '0' disables
171 retry and '1' enables it. If not given, the Torus record may
172 specify with element retryOnFailure (value '0'/'1').
176 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
177 instead of just a child process. Extremely rare in real life, hit me with
178 CF stress testing. MP-559.
182 http_file: passthru option MP-557
183 New facility for http_file to passthru - even if an area is matched. The
184 default behavior (passthru=false) is to return 404: Not found. With
185 passthru=false, next filter is consulted.
189 Fix ref to freed memory in log filter 1line - MP-556
191 echoedSearchRetrieveRequest support MP-555
195 zoom: allow hostname to be given for ipauth MP-552
196 The Torus setting for that is called auth_hostname.
200 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
204 session_shared: close in ~BackendInstance MP-549
205 This fixes a serious issue where some MP would leak sockets.
207 session_shared: mutex lock in BackendClass::release_backend MP-550
208 Fixes a SEGV that could occur (in rare cases).
212 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
214 zoom: fix invalid present response in some cases MP-546
216 zoom: Relay Torus HTTP error message
220 Check for proper limits before using RecordCache functions MP-544
224 Build packages for Ubuntu Trusty Tahr 14.04 LTS

230 doc: fix missing man pages MP-542
232 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
234 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
238 sru_z3950: fix facet response (memory corruption) MP-532
240 log: fix crash idPass user is omitted MP-530
244 query_rewrite: pass-thru non Type-1 queries MP-527
246 metaproxy stop (SIGTERM) kills all child processes spanwed by
247 filter (if any) before invoking filter destructors. MP-525
251 http_file: only supports HTTP GET MP-523
253 session_shared: shut down expire thread in destructor
254 This ensures that expire thread is not running after destruction
255 and does bad memory references, etc.
257 frontend_net: fix segfault on startup MP-524
258 Would happen if MP was listening on multiple ports and one
259 of the ports was already in use (and MP would exit).
261 frontend_net: fix memory leak MP-521
262 This leak would occur if all sessions were in use and the input
263 queue was cleared when a client would close connection (socket).
265 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
269 http_rewrite: use local skiplist; fixes memory corruption. MP-520
271 http_client: x-forwarded-for controls X-Forwarded-For presence
272 If x-forwarded-for setting (boolean) is enabled, http_client will
273 generate an X-Forwarded-For header entry which includes existing
274 X-Forwarded-For (if any) and current peer address (immediate client
275 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
276 will not be generated.
278 z3950_client: client_ip controls client-IP presence
279 If client_ip setting (boolean) is enabled, z3950_client will
280 generate a client_ip OID as part of init request which includes
281 previous client_ip (if any) and current peer address (immediate
282 client of Metaproxy). By default client_ip is disabled and client_ip
283 will not be generated.
285 HTTP X-Forwarded-For/Z39.50 Client-IP support
286 virt_db, multi: relays Z39.50 client-IP.
287 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
288 zoom: uses Client-IP or origin address (prefer Client-IP).
289 frontend_net: Strips tcp: from peer address (so that it is no longer
290 printed and stripped in zoom filter).
291 z3950_client: builds client-IP list - combining immediate peer address
292 as returned by COMSTACK and existing client-IP list (if avaiable).
293 The Origin only printes first X-Forwarded address.
297 Log when SIG{TERM,USR1} is received ASAP MP-513
298 Do it in frontend_net event loop rather than in place for metaproxy
299 main, which only exits when all sessions are terminated for SIGUSR1
302 metaproxy-config: quote some RHS values (that might include blanks)
304 Fix leak in sru_z3950 filter - when explain is returned MP-511
306 Allow stylesheet to be given for sru_z3950 filter MP-510
307 This is based on a patch by Sven Porst and the functionality
308 of the YAZ Generic Frontend Server.
310 Allow base attribute in configuration file tags - the attributes are
311 inserted by XInclude usage as mentioned on
312 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
313 and noted in a gist: https://gist.github.com/3551094
315 Package metaproxy provides virtual package metaproxy6 MP-508
316 This allows module packages to depend on a metaproxy server
319 Filter destructors called upon daemon termination MP-505
320 When metaproxy daemon receives SIGTERM the stop method of each filter
321 is called. The stop method existed before, but did not take any
322 arguements (void).. The frontend_net filter can now distinguish
323 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
324 (stop immediately). Note that this changes the API+ABI of Metaproxy
327 zoom: sync up with Pazpar2 WRT authentication handling MP-492
329 Router: use shared_ptr rather than naked one - to avoid leak if an
330 exception is thrown in configure.
334 zoom: Add nocproxy=1 for contentConnector sessions MP-501
336 Doc: mention proper versions; fix link to Boost win binaries.
338 Windows: update for Boost 1.55
340 Windows: avoid warning when using boost::split. Done by defining
341 _SCL_SECURE_NO_WARNINGS for Visual Studio.
343 Fix LSB conformance for /etc/init.d/metaproxy MP-500
344 Debian: add support for /etc/init.d/metaproxy status
346 sort: Add const to Record less than operator in order to compile on
351 session_shared: fix element-set handling in record caching. MP-499
353 document http_rewrite. MP-468
355 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
356 respects the header (which will normally come from the cproxy filter)
360 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
361 RPM was unsable in version 1.4.0.
363 Remove log message about "backend classes". Appeared in version 1.4.0.
367 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
368 with older version from source, but packages now use YAZ 5 that supports
371 sru_z3950: Fix SEGV for decoding invalid SRU requests
372 Incorrect reference to union (was explain response rather than
375 session_shared: match additionalSearchInfo (includes facets). In
376 layman's terms means that means that facets are properly handled
377 by this filter. Eg a change in requested facets will issue new
378 search and facets from exisiting result set are cached.
380 --- 1.3.62 2013/09/11
382 http_rewrite: better handling of <script> content in HTML parser. MP-486
384 http_rewrite: fix threading issue with regex. MP-482
386 bounce: don't use strdup for fixed length content. Error occurred in echo
389 session_shared: expire backend class when no instances left. This
390 means memory clean up, but not really a leak fix.
392 virt_db: fix leak for naked ptr.
394 cql_rpn: use config relative path for cql2rpn file. MP-481
396 Updates for upcoming YAZ 5.
398 --- 1.3.61 2013/08/29
400 New configuration directories ports.d/routes.d for metaproxy
401 configuration. This allows 3rd party packages to install config
402 for ports and new routes. MP-477
404 --- 1.3.60 2013/08/21
406 Fix metaproxy-config --libs to return non-mt over mt libs.
407 The -mt versions do not exist as shared objects and cause
408 linker errors for applications linking with Metaproxy.
409 Problem present in versions 1.3.56 - 1.3.59. MP-475
411 HTML: clean up char checks. Add ptr to HTML parse spec
413 HTML parser stops eating tag when <-char is met MP-473
415 rewrite: do not even compare content types, if we don't have any
416 the regex_match caused a segfault if we had no content-type in the
419 rewrite: within header=... matches only the header value
420 Used to match the whole header line, but we need to use
421 ^$ anchoring for host-relative regexps, and they need to
422 anchor at the ends of the value. MP-470.
424 rewrite: Ruleset functional MP-469
426 --- 1.3.59 2013/07/12
428 session_shared: negotiate init sz parameters.
429 By default, session_shared will honor the paramters given by client.
430 An alternative, but not implemented, algorithm would be to only
431 re-use sessions with same sz parameters. This however, could reduce
432 re-use of sessions a lot. Hence this, simple algorithm instead. The
433 negotiation to a maximum sz values can be enabled by using
434 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
435 in configuration. This will make session_shared send those values
436 to backends and use returned init values in negotaition to
437 client before session_shared.
439 session_shared: resolve result-set references.
440 The reference is substitued with the query for old set if database
441 match and query type is Type-1. If not the reference will issue a
444 sort filter: relays RecordComposition including elementSet in use for
447 http_client: better diagnostics
449 http_client: disables HTTP redirect handling by default.
450 It can be configured with max-redirects in configuration.
452 --- 1.3.58 2013/06/12
454 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
456 --- 1.3.57 2013/06/12
458 Make RouterChain and RouterXML part of public API (libmetaproxy).
460 http_client: honor X-Metaproxy-Proxy as an alternative to
461 the "proxy" configuration. Allows proxy to be set per HTTP request.
463 sru_z3950: For SRU requests recognize x-client prefixes as a way
464 to ingest "database parameters".. The suffix of x-client- serves
465 as database argument name. Multiple may be given. For example:
466 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
467 is turned into Z39.50 database
470 --- 1.3.56 2013/05/27
472 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
474 New filter sd_remove, which replaces surrogate diagnostics with
475 SUTRS records. This filter tries to deal with clients that breaks
476 when receiving surrogate diagnostics.
478 new filter http_client. Same role as z3950_client, but just for
479 HTTP. Allows Metaproxy to operate as a HTTP proxy.
481 New filter http_rewrite1, which serves as purpose on how to rewrite
482 HTTP content with Metaproxy.
484 Use libboost-system if available, because newer versions of libboost-threads
485 requires libboost-system.
487 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
490 --- 1.3.55 2013/04/10
492 zoom: Torus setting: authenticationMode which may hold values "basic"
495 --- 1.3.54 2013/03/27
497 configure: check for Libxslt support in YAZ and rely on definitions
498 from yaz-config, rather than doing own xslt/xml2 checks.
500 Allow timestamp format for log lines to be given with option -m
501 for metaproxy. Similar to yaz-ztest/GFS option -m.
503 Document log category 'line' for log filter.
505 Solr configuration example in etc/config-solr.xml
507 multi: do not mess with request package. For scan and search,
508 database-names were modified and the request package was left with
509 dangling pointers that caused a log filter to fail (request package
510 inspected after multi was invoked).
512 Documentation: fix id of metaproxy-config ref .
514 Documentation: update for USEMARCON support.
516 --- 1.3.53 2013/01/31
518 record_transform: allow OPACXML to OPAC conversion
520 zoom: document content-proxy
522 zoom: document db parm content-{user,password}, torus_url. Also
523 <torus auth_url="..> which makes zoom operate in authenticated mode
526 --- 1.3.52 2012/11/30
528 zoom: fix http://-check. SRU search broken in 1.3.51.
530 --- 1.3.51 2012/11/15
532 zoom: only append http:// for SRU if not already given . Makes it
533 possible to use https-URLs.
535 Use yazpp 1.4 or later due to new ABI.
537 frontend_net: allow max package size to be specified. Controlled by
538 attribute 'max_recv_bytes' of element 'port'.
540 --- 1.3.50 2012/10/29
542 For most generated diagnostics by filters, typically temporary
543 system error, augment addinfo message with filter name.
545 Add support for CentOS 6 packages.
547 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
549 Add man page for metaproxy-config.
551 --- 1.3.49 2012/10/18
553 zoom: new config element passthru. This defines an element set that is
554 passed verbatim to the backend in pz2 mode.
556 auth_simple: allow both idPass and open auth. Also fix SEGV that could
559 --- 1.3.48 2012/10/08
561 z3950_client: fix string handling for init diagnostics in the case where
564 query_rewrite: no charset conversion for error queries. Avoid performing
565 charset conversion for query conversion errors. The resulting Type-1
566 query is invalid in this case.
568 --- 1.3.47 2012/10/04
570 For graceful stop (SIGUSR1), metaproxy will kill children processes.
572 Log when metaproxy is invoked in test mode (-t).
574 Log PID for each log message.
576 multi: combine both NSDs and multiple NSDs into one (diagnostics).
578 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
579 a (backend=target) is appended for each diagnostic so that can be
580 determined the origin of error.
582 multi: hideerrors also in use for present response.
584 Solr example in zoom man page.
586 Fix typo in query_rewrite config example.
588 Log at least first non surrogate diagnostic. Instead of
589 "Z_Records_multipleNSD"
591 multi: Fix check for opt Records in present response. A SEGV could occur
592 if a target did not return records and no diagnostics.
594 --- 1.3.46 2012/09/24
596 Yet another fix for graceful stop.
598 --- 1.3.45 2012/09/12
600 sru_z3950: relay surrogate diagnostics.
602 --- 1.3.44 2012/09/10
604 zoom: Honor extraArgs, strip # in zurl.
606 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
608 zoom: url_recipe allow %{var[reg]} substitutions.
609 It's like ${var[reg]} but does URI component encoding as well.
611 --- 1.3.43 2012/08/22
613 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
614 non-keepalive HTTP sessions.
616 http_file: allow zero size files (bug fix)
618 Fix zoom schema: auth_url is optional
620 --- 1.3.42 2012/08/20
622 zoom: fix un-init memory (could result in SEGV at session close)
624 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
625 and may be used in filters as usual.
627 zoom: authentication via Torus lookup
628 Enabled by new configuration setting: auth_url . If this is defined,
629 the zoom module will contact Torus for auth/IP lookup and that will
630 define realm to be used in session.
632 --- 1.3.41 2012/08/10
634 virt_db: Fix database name - first character we removed by mistake.
635 Bug introduced in 1.3.40.
637 --- 1.3.40 2012/08/06
639 virt_db: Don't use "unix path" as database for Unix sockets.
641 --- 1.3.39 2012/08/02
643 z3950_client: Don't tamper with / in zurl - fixes problems
644 using Unix sockets for backends.
646 session_shared: fix integer overflow problem with hit count.
648 session_shared: avoid long usage of cached queries.
650 zoom: New database argument , torus_url to set URL of Torus
651 record to be fetched.
653 --- 1.3.38 2012/07/04
655 Fixes for 'metaproxy reload' for RPM/Debian packages.
657 zoom: Allow rpn2cql conversion to be augmented with a properties file.
658 Element rpn2cql can be specified per-target for the zoom filter.
660 log: New category "line" which is a single-line log message with
661 most important parts of a HTTP/Z39.50 request/response.
663 --- 1.3.37 2012/06/01
665 frontend_net: add facility to report live statistics about response
666 times and current thread usage. The report is an XML document
667 and is triggered for a specific URL path. This is set by <stat-req>
668 in the configuration of frontend_net. By default this report is
669 disabled (same as empty value for <stat-req>).
671 Fix reload problem in init.d script for RPM/Debian.
672 The '/etc/init.d/metaproxy reload' in some cases would stop but not
673 start metaproxy - effectively stopping the service.
675 Don't display start log message when config testing (-t).
677 zoom: avoid CCL message limit of 1K in ZOOM filter.
679 --- 1.3.36 2012/05/10
681 metaproxy init script reacts to reload which does graceful stop +
682 start and is used by logrorate script.
684 --- 1.3.35 2012/05/09
686 Fixes for Windows compilation.
688 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
689 existing sessions running but terminate the monitor process that is
690 used in keepalive mode.
692 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
693 before. Consistent with 'metaproxy stop' message.
695 zoom: document zoom's proxy_timeout
697 z3950_client: fixup addinfo for init response
699 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
700 "Access to specified database denied" is returned, but only if init
701 response from backend does not carry diagnostics already.
703 multi: relays user info for first rejected target. The other-information
704 field for init response for first rejected target is in common init
705 response. This ensures that some backend init diagnostics are returned to
708 --- 1.3.34 2012/04/25
710 frontend_log: extend logging (when message is given in config).
712 --- 1.3.33 2012/04/25
714 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
716 --- 1.3.32 2012/04/24
718 sru_z3950 filter passes through incoming Z39.50 requests again. Was
719 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
721 --- 1.3.31 2012/04/24
723 zoom: fixes for retry/proxy failover logic. More logging.
725 --- 1.3.30 2012/04/23
727 zoom: return addinfo="proxy failure" for proxy failures. This also
728 changes the scheme for dealing with proxies a bit. zoom now always
729 do proxy check, even if there's no failover. Fortunately, that's not
732 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
733 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
734 generic. We don't know why the init would fail; IP, user, block IP, etc.
735 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
737 zoom: guess if invalid SRU response was an auth failure
739 session_shared: disable session retry by default . Can be enabled by
740 restart="true" in resultset section.
742 --- 1.3.29 2012/04/18
744 zoom: may read cf-proxy's config settings.
745 This reduces manual configuration of the content proxy server host.
746 The ZOOM module will use the old style session.proxyhost if "server"
747 is given (deprecated) and use the new style proxyhost/session if
748 "config_file" is in use.
750 frontend_net: remove incoming requests that can not be handled
751 Requests in queue for filter frontend_net are removed if client
752 closes connection for the session and request is not yet handled.
754 sru_z3950: serialize requests. This is to ensure that pipelined
755 HTTP requests are handled properly.
757 --- 1.3.28 2012/04/04
759 New class, wrbuf, that wraps YAZ' WRBUF.
761 --- 1.3.27 2012/03/30
763 Metaproxy daemon is now running as user "metaproxy". This user is
764 managed by package maintainer scripts. The user information is stored
765 in /etc/metaproxy/metaproxy.user .
767 --- 1.3.26 2012/03/20
769 New filter, sort, that allows sorting of XML records via Z39.50
772 Filter record_transform: USEMarcon support. For example:
773 <retrieval syntax="usmarc">
774 <backend syntax="unimarc" name="F">
775 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
779 Filter multi: empty route pattern uses route as default.
781 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
782 may use the shorter notation
783 <target route="z3950.indexdata.com"/>
785 Filter query_rewrite: use config path to locate XSLT.
787 Filter frontend_net: log statistics.
788 If a custom message element in frontend_net configuration it makes
789 the frontend_net filter produce a log entry whenever an operation
790 is completed. The log is always written using yaz_log with the
791 custom message given, the package ID (session ID) , the time
792 the operation has been active (end-to-end) , the threads currently
793 active/total and the size of the request input/output queues.
795 query_rewrite: charset conversion of query terms.
796 This is an optional feature. Enabled by element <charset> in
797 configuration with attribute 'from' and 'to' that specifies
798 from/to encodings. The default 'from' encoding is UTF-8.
800 Filter record_transform: honor piggyback searches.
802 Filter zoom: re-connect when database is reused.
803 Re-connect is necessary if a connection is lost or a timeout occurs.
804 If not, we'll be seeing zero hits, when we shouldn't.
806 --- 1.3.25 2012/02/29
808 zoom: Change scheme for dealing with content proxy URLs. The module
809 now has its own common XSL transform that is enabled by record_xsl
810 attribute in the configuration. This XSL gets parameter cproxyhost
811 that holds the host for the content proxy session . The genearted-url
812 is created only if urlRecipe is enabled. In previous version default
813 value of urlRecipe was ${md-electronic-url}; it is now empty and
814 disabled by default. Also generated-url no longer includes the content
815 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
818 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
819 connections. Default value is 40 (seconds).
821 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
822 "Malformed query" for syntax errors and related ones; throw
823 Bib-1: 3 "Unsupported search" for everything else. Details from
824 the CCL parser is provided as additional-info.
826 multi: new setting hideerrors that makes multi only relay diagnostics
827 to a client if all backends fail.
829 --- 1.3.24 2012/02/23
831 zoom: empty ccl_map field-mappings disables CCL map.
833 zoom: fix Explain search that could return error if session was
836 --- 1.3.23 2012/02/10
838 zoom: returns Explain records for database IR-Explain---1. The
839 target profile records are converted to Explain records via XSLT.
841 session_shared: make error recovery configurable. Whether a search
842 is restarted on errors or not, is configurable by attribute "restart"
843 in element "resultset" in configuration.
845 session_shared: only relay init for first request. session_shared, for
846 each backend class, now only relays first init request (rather than all).
847 The module only needs to save init response info once. This avoids the
848 need to check for session max.
850 --- 1.3.22 2012/02/02
852 zoom: fix memory leaks.
854 session_shared: maximum number of sessons is configurable. Default
855 value is 100. Result-sets for backends without named result sets are
856 only re-used if databases is identical for a search. This is under the
857 assumption that performance may suffer for those backends when
858 changing the database for each search.
860 multi: combines diagnostics from all backends. All diagnostics from
861 backends are combined into multiple non-surrogate diagnostics; rather
862 than just one diagnostic from first backend.
864 --- 1.3.21 2011/12/27
866 zoom: relay realm to cproxy parameter file.
868 Configuration: Allow filter collection element inside route. This
869 makes it possible to include multiple filters at once.
871 zoom: nocproxy also disables urlRecipe.
873 --- 1.3.20 2011/12/21
875 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
876 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
877 90: "Unsupported direction value".
879 zoom: honor database argument nocproxy. This disables creating a content
880 connector session (for non-CF targets, usually) and also relays nocproxy
881 as database argument to a CF target.
883 --- 1.3.19 2011/12/16
885 zoom: Multiple proxy hosts may be given for proxy rich database
886 parameter. List is comma separated.
888 http_file: decodes URI paths properly. Does not return 404: not found
889 if no prefix are matches. Instead packages are passed on.
891 --- 1.3.18 2011/12/08
893 zoom: content-{user,password,proxy} are passed on to content proxy
894 system and takes precedence over user,password,proxy .
896 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
897 with a log element including log material from children filters. At
898 this point, only the zoom filter uses this log facility. It will
899 eventually be used by other filters as well. In particular it might be
900 useful for this feature to track all filters in used during a search.
902 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
903 and queries as they are manipulated are logged.
905 zoom: extend addinfo with native diagnostics. Diagnostics as received
906 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
907 diagnostics. This indicates both a backend diagnostic and the original
910 zoom: default urlRecipe value is ${md-electronic-url}
912 zoom: target profile setting sruVersion is recognized.
914 --- 1.3.17 2011/11/17
916 zoom: log target profile record fetched (AKA Torus).
918 --- 1.3.16 2011/11/17
920 Change target profile parameter CfSubDb to CfSubDB.
922 --- 1.3.15 2011/11/12
924 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
925 makes sense to the zoom module itself).
927 --- 1.3.14 2011/11/11
929 zoom: realm may be given as part of database.
931 --- 1.3.13 2011/10/26
933 Fix Origin class assigment method; was removd by mistake in 1.3.12.
935 --- 1.3.12 2011/10/26
937 zoom: database args x-name=value are passed through to backend database.
939 SRU filter: user may specify session ID that is passed to log entries
940 that follows. It is specified by using x-session-id in the SRU arguments.
942 zoom: fix null pointer reference which would occur for bad url parameter
943 inside "torus" or if url was not given.
945 --- 1.3.11 2011/09/09
946 Fix bug in filter session_shared where sessions would not expire
947 properly (session ttl). This in turn could make the target close the
948 connection before expected and session_shared would return diagnostic
949 2: system temporarily available.
951 --- 1.3.10 2011/09/09
953 zoom: new target profile setting: sortmap_field. If sortmap_field is given
954 the field is mapped to the value for the sortmap. Values not matching
955 sortmap_field are passed verbatim.
957 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
958 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
959 depending on whether RPN or CQL is actually sent to the target.
963 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
965 zoom: For content proxy authentication is stored in param name
966 "auth", instead of "authentication".
970 zoom: relay schema in SRU mode. Previously recordSchema was not affected
975 zoom: new target profile element literalTransform that holds XSLT
976 (encoded as string) for target. Only if present and non-zero length it is
977 considered present. This takes precedence over transform.
979 Don't rely on trang anymore for Git checkout builds. Configuration in etc
980 will only be properly validated if trang is available. From now on only
981 relax NC files are bundled with the source dist.
983 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
984 component was not detected when it should be.
988 z3950_client: mark non-surrogate diagnostics from backend.
990 zoom: a proxy may be specified for HTTP fetch of target profiles.
994 Honor piggyback. Makes some SRU targets behave that insist on
995 maximumRecords > 0, but also increases performance.
999 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
1000 file was not update for libdir/metaproxy4 in version 1.3.2.
1002 --- 1.3.2 2011/08/01
1004 Change location of Metaproxy modules from libdir/metaproxy to
1005 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
1006 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
1008 New facility to dump APDUs from zoom filter. Enabled by
1009 <log apdu="true"/> in the zoom filter configuation.
1011 zoom filter bug fix: SRU diagnostics received from backend was
1012 not properly converted to Bib-1 diagnostics.
1014 Package metaproxy depends on libmetaproxy4, same version.
1016 --- 1.3.1 2011/07/28
1018 zoom: fix a bug WRT passing authentication parameters to backends.
1020 --- 1.3.0 2011/07/27
1022 Fixes for windows Makefile.
1024 --- 1.2.10 2011/07/25
1026 Change major version of metaproxy library from 3 to 4. This in turn
1027 makes new package names for Debian and RPM.
1029 --- 1.2.9 2011/06/27
1031 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
1034 zoom: configurable element sets for record transforms.
1036 zoom: the target profile based transform is specified by element_transform
1037 in element torus of of the ZOOM filter configuration ; default value
1038 is "pz2". Target profile based retrieval is specified by element_raw
1039 in configuration. It will perform same steps, but omit the XSL transform.
1040 Default value is "raw".
1042 zoom: element set is omitted if not set in profile. But only if pz2
1043 transform is in effect. Previously the default element set was to "F".
1045 zoom: For non-CF targets database arguments are parsed. User may supply
1046 db,user=myuser&password=mypass for non-CF targets. These values override
1047 what's given the authentication from the target profile.
1049 session_shared: fix reference to freed memory. Would occur if a search
1050 response had non-surrogate diagnostics.
1052 --- 1.2.8 2011/06/22
1054 Route may be given for each port in frontend_net.
1056 --- 1.2.7 2011/06/22
1058 Documentation for zoom filter. Local target profiles may be specified.
1060 Fixes for zoom filter.
1062 --- 1.2.6 2011/06/15
1064 First version with zoom filter.
1066 --- 1.2.5 2011/05/06
1068 Filter z3950_client may be configured to always send a close APDU
1069 to backend target when connection/session is closed. This will only
1070 happen if close APDU is not already sent. Enabled by configuration
1071 for z3950_client (force_close).
1073 Filter virt_db and multi: relay close APDU.
1075 Filter virt_db and multi: relay init size parameters
1076 preferredMessageSize and maximumRecordSize.
1078 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
1080 --- 1.2.4 2011/01/27
1082 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
1084 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
1085 as determined by configure.
1087 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1088 this package can be distinguished from other vendors.
1090 --- 1.2.3 2010/10/04
1092 Fix filter multi: relay idAuthentication parameters.
1094 --- 1.2.2 2010/09/15
1096 Add metaproxy-config for returning compiler flags, libraries.
1098 --- 1.2.1 2010/08/18
1100 Fix --with-boost=PREFIX .
1102 --- 1.2.0 2010/07/09
1104 session_shared: fix use of maintenance thread.
1106 Introduce 'start' method for filters and routers. It gets called after
1107 configure and after fork, but before processing. This changes API -
1108 from libmetaproxy2 to libmetaproxy3.
1110 --- 1.1.7 2010/06/30
1112 session_shared: ensure backend session is closed if init rejected
1115 z3950_client: fix NULL ptr reference that could occur if two clients
1116 connected concurrently and if max-sockets was in effect.
1118 --- 1.1.6 2010/06/21
1120 Fix bug 3497 - Metaproxy unstable while stopping.
1122 Fix bug 3495 - SEGV in SRU filter.
1124 --- 1.1.5 2010/06/15
1126 Filter multi throws diagnostic 'Present Out of Range' when
1127 appropriate - rather than returning 0 records.
1129 Filter virt_db: fix bad result reuse. Could happen if a result
1130 was overriden and a backend did not supported named result sets.
1132 --- 1.1.4 2010/05/11
1134 Filter log: category access logs diagnostics even if searchStatus
1135 or presentStatus is 'success'.
1137 --- 1.1.3 2010/04/21
1139 The SRU to Z39.50 filter does repeated Z39.50 present requests
1140 to fetch all records. Needed when a Z39.50 server returns partial
1141 results (due to message size limits).
1143 --- 1.1.2 2010/03/18
1145 Metaproxy now kills all child processes that are spawned by
1146 modules (in case of fork, exec).
1148 --- 1.1.1 2010/01/28
1150 Debian package now installs /etc/metaproxy/metaproxy.xml which
1151 includes all XML files /etc/metaproxy/filters-enabled .
1152 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1154 --- 1.1.0 2010/01/20
1156 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1157 development package to facilitate 3rd party Metaproxy modules.
1159 --- 1.0.23 2010/01/04
1161 Filter virt_db: Close backend filter session when Init rejected is received
1162 from it (in which case it's not really closed yet). This will ensure we don't
1163 run out of resources such as FDs in this case.
1165 sru_z3950 filter: Accept any database (including those not listed).
1167 --- 1.0.22 2009/12/03
1169 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1170 later which means YAZ 3.0.47 or later.
1172 --- 1.0.20 2009/11/19
1174 For filter virt_db, the database is a glob pattern and the virtual
1175 database sections are consulted in the order given.
1177 --- 1.0.19 2009/07/08
1179 For filter multi, the target (for routing) may be given as a glob-pattern.
1181 More documentation for filters virt_db and multi.
1183 Update schema to allow for no database in sru_z3950 filter.
1185 --- 1.0.18 2009/06/30
1187 Added limit filter to put sleep (penalty) for heavy use.
1189 Filter frontend_net may be configured to limit the number of new connections
1190 from same IP to some value (connect-max).
1192 Fixed the load_balance filter.
1194 --- 1.0.17 2009/06/16
1196 Fix path for metaproxy executable for Debian init.d script.
1198 --- 1.0.16 2009/06/10
1200 SRU to Z39.50 filter honors x-username and x-password. If only
1201 x-username is given that translates to open authentication (Z39.50v2). If
1202 both x-username and x-password is present that translates to idPass
1203 authentication (Z39.50v3).
1205 New facility to change current working directory (-w).
1207 Update to upstream skeleton of init.d script. Should fix bug #2619.
1209 Filter session_shared now caches records (used to only cache connections
1212 Filter session_shared now invalidates a Z39.50 session if a server
1213 returns -1 hits. This facility was also part of yazproxy and gets around
1214 a bug in Voyager-based Z39.50 servers.
1216 --- 1.0.15 2008/11/18
1218 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1220 --- 1.0.14 2008/06/09
1222 Fixed the value of SRU record schema in searchRetrieve response. It was set
1223 to a fixed value of "dc" before.
1225 Serialize identical SRU requests. This is useful if HTTP client software
1226 fires identical requests against metaproxy.
1228 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1229 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1230 avoid static configuration. This facility is handled by the sru_z3950 module
1231 and the z3950_client module.
1233 Allow maximum number of sockets to be used for a Z39.50 client by the
1234 use of SRU extra parameter x-max-sockets. This facility is handled by the
1235 sru_z3950 module and the z3950_client module.
1237 --- 1.0.13.1 2008/02/29
1239 Simplified check for Boost libraries.
1241 --- 1.0.13 2008/02/29
1243 First Debian package.
1245 The sru_z9350 filter now recognizes SRU parameter z-target as being
1246 a ZURL of the form host/database .
1248 Mergetype may be specified for filter 'multi'.
1250 --- 1.0.12 2007/09/19
1252 Fixed problem in Makefile WRT library specifictions. This could produce
1253 linker errors (when they should not happen).
1255 Fixed bug #1341: MetaProxy returning different results. Problem was that
1256 fix-up of record database did not normalize the database name.
1258 Documentation updates for Windows compilation.
1260 --- 1.0.11 2007/06/14
1262 Fixed problem with logfile being truncated.
1264 --- 1.0.10 2007/05/23
1266 Fixed bug #1136: Access rights not enforced.
1268 Extension for log module. The log category 'access' logs more details.
1269 New category 'user-access' added which is simlar to 'access' but adds
1270 the Z39.50 user as for all entries in a session.
1274 Added support for configurable default/force target/vhost for module Z39.50
1277 --- 1.0.8 2007/01/25
1279 Implemented filter, session_shared, which optimizes usage of Z39.50
1280 sessions and result sets.
1282 New filter, record_transform, which converts MARC/XML records.
1284 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1286 New filter, load_balance, in development.
1288 New filter, zeerex_xplain.
1290 XML framework for config files started.
1292 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1293 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1294 XML config files are checked against RNG and XML Schema's.
1296 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1297 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1298 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1299 explain record to YAZ CQL-to-PQF text config file.
1301 --- 1.0.7 2006/11/07
1303 Added 'timeout' setting for filter frontend_net which specifies the number
1304 of seconds a session is idle before it is closed. Default timeout is
1307 --- 1.0.6 2006/07/07
1309 Database name in records returned set for virt_db/multi filters.
1311 Filter session_shared now functional.
1313 Log filter can be configured to write to a given file using 'filename'
1314 element. Also information category can be specified with 'category'. If
1315 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1318 --- 1.0.5 2006/05/16
1320 Fixed compilation on Windows.
1322 --- 1.0.4 2006/05/16
1324 Added documentation for the hidenavailable option for the multi filter.
1326 --- 1.0.3 2006/05/16
1328 Fixed bug #573: Hide errors for individual servers. If the element
1329 'hideunavailable' is given in the configuration, individual servers
1330 being unavailable are hidden (unless all are unavailable).
1332 Fixed bug #574: Database names are recognised case-sensitively.
1334 Fixed bug #567: Fix up database name in Name-Plus-Record.
1336 Fixed bug #568: Update win/makefile for VS 2005.
1338 Fixed bug #569: Some options throws unknown exception.
1340 --- 1.0.2 2006/04/28
1342 More information about virtual hosts. The 'etc' directory is part of the
1345 --- 1.0.1 2006/04/27
1347 Build instructions for Windows. NMake makefile part of distribution tar.
1349 --- 1.0.0 2006/04/24
1353 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1354 log, multi, query_rewrite, template, virt_db, z3950_client.
1356 Filters in development: session_shared.
1358 Pseudo-filters: template, dl
