39 Fix systemd: reload stops metaproxy MP-620
40 Detect systemd and just do nothing when reload/force-reload is
41 used. Log, however, that it really is not reloading.
43 Add http-req-max to frontend_net MP-617
47 Fix multi: hideunavailable don't hide target that timeout MP-615
51 Fix race condition in MP log output MP-522
53 Fix 'Group' is duplicated twice in RPM spec

57 Change target z3950.loc.gov:7090/voyager -> lx2.loc.gov:210/LCDB_MARC8
60 Fix Control-C does not stop Metaproxy spawned by shell MP-610
61 Check for fork mode instead (-D) - rather than debug (-X)
65 sru_z3950: allow CCL in SRU search MP-606
66 Makes the sru_z3950 filter convert to CCL queries if query type
67 "ccl" is used, eg ?query=water&queryType=ccl&... for SRU 2.0.
71 Fix dead lock in session_shared (init) MP-605
75 Fix session_shared caches set with diagnostic MP-604
77 Fix assertion failed in session_shared filter MP-603

81 Log YAZ version upon start MP-599
85 sru_z3950: undo Serialize identical SRU GET requests MP-598
86 Now much more elegantly handled by session_shared.
88 session_shared: anticipated init and search MP-597
90 z3950_client: separate init timeout MP-596
91 Both init-timeout and connect-timeout are configurable by this change.
92 Default is 10 seconds.
96 zoom: support cf_-params MP-595
98 http_client: returns 404 if no destination URI is given
102 zoom: allow / in user and password db args MP-592
106 Log rotate no longer reloads configuration - instead Metaproxy just
107 re-opens log files when SIGHUP is received. MP-485
109 Debian : init.d metaproxy reload should check configuration MP-591
111 Fix Metaproxy stops logging after check config failed MP-590
115 Fix double free in log filter (with incorrect config) MP-589
117 zoom: Add allow_ip feature - fixes MP-588
118 Allow a list of IPs to be given separated by blanks
119 <allow auth_url="http://mkc-admin.indexdata.com/..."
120 allow_ip="127.0.0.1 ::1" .. >

152 Add support for binding outgoing IP for http_client and z3950_client
153 This is enabled by bind_host setting. MP-575
157 z3950_client: allows negotiation charset to be set MP-574
159 cgi: more functional but no support for POSTed content yet (part of MP-564)

163 http_file: add include of sys/stat.h fixes MP-576
165 Fix documentation about SRU client support MP-572
167 Initialize Libxml2 - for threaded operation MP-571
169 --- 1.5.10 2014/08/26
171 On SIGTERM shut down connection+listening sockets MP-568
172 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
176 zoom: make retry on failure configurable MP-565
177 The default and existing behavior is that backend failures (any
178 diagnostic) makes the module re-search once. The behavior may
179 be changed by db parameter 'retry'. If given value '0' disables
180 retry and '1' enables it. If not given, the Torus record may
181 specify with element retryOnFailure (value '0'/'1').
185 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
186 instead of just a child process. Extremely rare in real life, hit me with
187 CF stress testing. MP-559.
191 http_file: passthru option MP-557
192 New facility for http_file to passthru - even if an area is matched. The
193 default behavior (passthru=false) is to return 404: Not found. With
194 passthru=false, next filter is consulted.
198 Fix ref to freed memory in log filter 1line - MP-556
200 echoedSearchRetrieveRequest support MP-555
204 zoom: allow hostname to be given for ipauth MP-552
205 The Torus setting for that is called auth_hostname.
209 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
213 session_shared: close in ~BackendInstance MP-549
214 This fixes a serious issue where some MP would leak sockets.
216 session_shared: mutex lock in BackendClass::release_backend MP-550
217 Fixes a SEGV that could occur (in rare cases).
221 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
223 zoom: fix invalid present response in some cases MP-546
225 zoom: Relay Torus HTTP error message
229 Check for proper limits before using RecordCache functions MP-544

249 log: fix crash idPass user is omitted MP-530
253 query_rewrite: pass-thru non Type-1 queries MP-527
255 metaproxy stop (SIGTERM) kills all child processes spanwed by
256 filter (if any) before invoking filter destructors. MP-525
260 http_file: only supports HTTP GET MP-523
262 session_shared: shut down expire thread in destructor
263 This ensures that expire thread is not running after destruction
264 and does bad memory references, etc.
266 frontend_net: fix segfault on startup MP-524
267 Would happen if MP was listening on multiple ports and one
268 of the ports was already in use (and MP would exit).
270 frontend_net: fix memory leak MP-521
271 This leak would occur if all sessions were in use and the input
272 queue was cleared when a client would close connection (socket).
274 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
278 http_rewrite: use local skiplist; fixes memory corruption. MP-520
280 http_client: x-forwarded-for controls X-Forwarded-For presence
281 If x-forwarded-for setting (boolean) is enabled, http_client will
282 generate an X-Forwarded-For header entry which includes existing
283 X-Forwarded-For (if any) and current peer address (immediate client
284 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
285 will not be generated.
287 z3950_client: client_ip controls client-IP presence
288 If client_ip setting (boolean) is enabled, z3950_client will
289 generate a client_ip OID as part of init request which includes
290 previous client_ip (if any) and current peer address (immediate
291 client of Metaproxy). By default client_ip is disabled and client_ip
292 will not be generated.
294 HTTP X-Forwarded-For/Z39.50 Client-IP support
295 virt_db, multi: relays Z39.50 client-IP.
296 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
297 zoom: uses Client-IP or origin address (prefer Client-IP).
298 frontend_net: Strips tcp: from peer address (so that it is no longer
299 printed and stripped in zoom filter).
300 z3950_client: builds client-IP list - combining immediate peer address
301 as returned by COMSTACK and existing client-IP list (if avaiable).
302 The Origin only printes first X-Forwarded address.
306 Log when SIG{TERM,USR1} is received ASAP MP-513
307 Do it in frontend_net event loop rather than in place for metaproxy
308 main, which only exits when all sessions are terminated for SIGUSR1
311 metaproxy-config: quote some RHS values (that might include blanks)
313 Fix leak in sru_z3950 filter - when explain is returned MP-511
315 Allow stylesheet to be given for sru_z3950 filter MP-510
316 This is based on a patch by Sven Porst and the functionality
317 of the YAZ Generic Frontend Server.
319 Allow base attribute in configuration file tags - the attributes are
320 inserted by XInclude usage as mentioned on
321 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
322 and noted in a gist: https://gist.github.com/3551094
324 Package metaproxy provides virtual package metaproxy6 MP-508
325 This allows module packages to depend on a metaproxy server
328 Filter destructors called upon daemon termination MP-505
329 When metaproxy daemon receives SIGTERM the stop method of each filter
330 is called. The stop method existed before, but did not take any
331 arguements (void).. The frontend_net filter can now distinguish
332 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
333 (stop immediately). Note that this changes the API+ABI of Metaproxy
336 zoom: sync up with Pazpar2 WRT authentication handling MP-492
338 Router: use shared_ptr rather than naked one - to avoid leak if an
339 exception is thrown in configure.
343 zoom: Add nocproxy=1 for contentConnector sessions MP-501
345 Doc: mention proper versions; fix link to Boost win binaries.
347 Windows: update for Boost 1.55
349 Windows: avoid warning when using boost::split. Done by defining
350 _SCL_SECURE_NO_WARNINGS for Visual Studio.
352 Fix LSB conformance for /etc/init.d/metaproxy MP-500
353 Debian: add support for /etc/init.d/metaproxy status
355 sort: Add const to Record less than operator in order to compile on
360 session_shared: fix element-set handling in record caching. MP-499
362 document http_rewrite. MP-468
364 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
365 respects the header (which will normally come from the cproxy filter)
369 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
370 RPM was unsable in version 1.4.0.
372 Remove log message about "backend classes". Appeared in version 1.4.0.
376 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
377 with older version from source, but packages now use YAZ 5 that supports
380 sru_z3950: Fix SEGV for decoding invalid SRU requests
381 Incorrect reference to union (was explain response rather than
384 session_shared: match additionalSearchInfo (includes facets). In
385 layman's terms means that means that facets are properly handled
386 by this filter. Eg a change in requested facets will issue new
387 search and facets from exisiting result set are cached.
389 --- 1.3.62 2013/09/11
391 http_rewrite: better handling of <script> content in HTML parser. MP-486
393 http_rewrite: fix threading issue with regex. MP-482
395 bounce: don't use strdup for fixed length content. Error occurred in echo
398 session_shared: expire backend class when no instances left. This
399 means memory clean up, but not really a leak fix.
401 virt_db: fix leak for naked ptr.
403 cql_rpn: use config relative path for cql2rpn file. MP-481
405 Updates for upcoming YAZ 5.
407 --- 1.3.61 2013/08/29
409 New configuration directories ports.d/routes.d for metaproxy
410 configuration. This allows 3rd party packages to install config
411 for ports and new routes. MP-477
413 --- 1.3.60 2013/08/21
415 Fix metaproxy-config --libs to return non-mt over mt libs.
416 The -mt versions do not exist as shared objects and cause
417 linker errors for applications linking with Metaproxy.
418 Problem present in versions 1.3.56 - 1.3.59. MP-475
420 HTML: clean up char checks. Add ptr to HTML parse spec
422 HTML parser stops eating tag when <-char is met MP-473
424 rewrite: do not even compare content types, if we don't have any
425 the regex_match caused a segfault if we had no content-type in the
428 rewrite: within header=... matches only the header value
429 Used to match the whole header line, but we need to use
430 ^$ anchoring for host-relative regexps, and they need to
431 anchor at the ends of the value. MP-470.
433 rewrite: Ruleset functional MP-469
435 --- 1.3.59 2013/07/12
437 session_shared: negotiate init sz parameters.
438 By default, session_shared will honor the paramters given by client.
439 An alternative, but not implemented, algorithm would be to only
440 re-use sessions with same sz parameters. This however, could reduce
441 re-use of sessions a lot. Hence this, simple algorithm instead. The
442 negotiation to a maximum sz values can be enabled by using
443 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
444 in configuration. This will make session_shared send those values
445 to backends and use returned init values in negotaition to
446 client before session_shared.
448 session_shared: resolve result-set references.
449 The reference is substitued with the query for old set if database
450 match and query type is Type-1. If not the reference will issue a
453 sort filter: relays RecordComposition including elementSet in use for
456 http_client: better diagnostics
458 http_client: disables HTTP redirect handling by default.
459 It can be configured with max-redirects in configuration.
461 --- 1.3.58 2013/06/12
463 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
465 --- 1.3.57 2013/06/12
467 Make RouterChain and RouterXML part of public API (libmetaproxy).
469 http_client: honor X-Metaproxy-Proxy as an alternative to
470 the "proxy" configuration. Allows proxy to be set per HTTP request.
472 sru_z3950: For SRU requests recognize x-client prefixes as a way
473 to ingest "database parameters".. The suffix of x-client- serves
474 as database argument name. Multiple may be given. For example:
475 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
476 is turned into Z39.50 database
479 --- 1.3.56 2013/05/27
481 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
483 New filter sd_remove, which replaces surrogate diagnostics with
484 SUTRS records. This filter tries to deal with clients that breaks
485 when receiving surrogate diagnostics.
487 new filter http_client. Same role as z3950_client, but just for
488 HTTP. Allows Metaproxy to operate as a HTTP proxy.
490 New filter http_rewrite1, which serves as purpose on how to rewrite
491 HTTP content with Metaproxy.
493 Use libboost-system if available, because newer versions of libboost-threads
494 requires libboost-system.
496 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
499 --- 1.3.55 2013/04/10
501 zoom: Torus setting: authenticationMode which may hold values "basic"
504 --- 1.3.54 2013/03/27
506 configure: check for Libxslt support in YAZ and rely on definitions
507 from yaz-config, rather than doing own xslt/xml2 checks.
509 Allow timestamp format for log lines to be given with option -m
510 for metaproxy. Similar to yaz-ztest/GFS option -m.
512 Document log category 'line' for log filter.
514 Solr configuration example in etc/config-solr.xml
516 multi: do not mess with request package. For scan and search,
517 database-names were modified and the request package was left with
518 dangling pointers that caused a log filter to fail (request package
519 inspected after multi was invoked).
521 Documentation: fix id of metaproxy-config ref .
523 Documentation: update for USEMARCON support.
525 --- 1.3.53 2013/01/31
527 record_transform: allow OPACXML to OPAC conversion
529 zoom: document content-proxy
531 zoom: document db parm content-{user,password}, torus_url. Also
532 <torus auth_url="..> which makes zoom operate in authenticated mode
535 --- 1.3.52 2012/11/30
537 zoom: fix http://-check. SRU search broken in 1.3.51.
539 --- 1.3.51 2012/11/15
541 zoom: only append http:// for SRU if not already given . Makes it
542 possible to use https-URLs.
544 Use yazpp 1.4 or later due to new ABI.
546 frontend_net: allow max package size to be specified. Controlled by
547 attribute 'max_recv_bytes' of element 'port'.
549 --- 1.3.50 2012/10/29
551 For most generated diagnostics by filters, typically temporary
552 system error, augment addinfo message with filter name.
554 Add support for CentOS 6 packages.
556 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
558 Add man page for metaproxy-config.
560 --- 1.3.49 2012/10/18
562 zoom: new config element passthru. This defines an element set that is
563 passed verbatim to the backend in pz2 mode.
565 auth_simple: allow both idPass and open auth. Also fix SEGV that could
568 --- 1.3.48 2012/10/08
570 z3950_client: fix string handling for init diagnostics in the case where
573 query_rewrite: no charset conversion for error queries. Avoid performing
574 charset conversion for query conversion errors. The resulting Type-1
575 query is invalid in this case.
577 --- 1.3.47 2012/10/04
579 For graceful stop (SIGUSR1), metaproxy will kill children processes.
581 Log when metaproxy is invoked in test mode (-t).
583 Log PID for each log message.
585 multi: combine both NSDs and multiple NSDs into one (diagnostics).
587 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
588 a (backend=target) is appended for each diagnostic so that can be
589 determined the origin of error.
591 multi: hideerrors also in use for present response.
593 Solr example in zoom man page.
595 Fix typo in query_rewrite config example.
597 Log at least first non surrogate diagnostic. Instead of
598 "Z_Records_multipleNSD"
600 multi: Fix check for opt Records in present response. A SEGV could occur
601 if a target did not return records and no diagnostics.
603 --- 1.3.46 2012/09/24
605 Yet another fix for graceful stop.
607 --- 1.3.45 2012/09/12
609 sru_z3950: relay surrogate diagnostics.
611 --- 1.3.44 2012/09/10
613 zoom: Honor extraArgs, strip # in zurl.
615 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
617 zoom: url_recipe allow %{var[reg]} substitutions.
618 It's like ${var[reg]} but does URI component encoding as well.
620 --- 1.3.43 2012/08/22
622 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
623 non-keepalive HTTP sessions.
625 http_file: allow zero size files (bug fix)
627 Fix zoom schema: auth_url is optional
629 --- 1.3.42 2012/08/20
631 zoom: fix un-init memory (could result in SEGV at session close)
633 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
634 and may be used in filters as usual.
636 zoom: authentication via Torus lookup
637 Enabled by new configuration setting: auth_url . If this is defined,
638 the zoom module will contact Torus for auth/IP lookup and that will
639 define realm to be used in session.
641 --- 1.3.41 2012/08/10
643 virt_db: Fix database name - first character we removed by mistake.
644 Bug introduced in 1.3.40.
646 --- 1.3.40 2012/08/06
648 virt_db: Don't use "unix path" as database for Unix sockets.
650 --- 1.3.39 2012/08/02
652 z3950_client: Don't tamper with / in zurl - fixes problems
653 using Unix sockets for backends.
655 session_shared: fix integer overflow problem with hit count.
657 session_shared: avoid long usage of cached queries.
659 zoom: New database argument , torus_url to set URL of Torus
660 record to be fetched.
662 --- 1.3.38 2012/07/04
664 Fixes for 'metaproxy reload' for RPM/Debian packages.
666 zoom: Allow rpn2cql conversion to be augmented with a properties file.
667 Element rpn2cql can be specified per-target for the zoom filter.
669 log: New category "line" which is a single-line log message with
670 most important parts of a HTTP/Z39.50 request/response.
672 --- 1.3.37 2012/06/01
674 frontend_net: add facility to report live statistics about response
675 times and current thread usage. The report is an XML document
676 and is triggered for a specific URL path. This is set by <stat-req>
677 in the configuration of frontend_net. By default this report is
678 disabled (same as empty value for <stat-req>).
680 Fix reload problem in init.d script for RPM/Debian.
681 The '/etc/init.d/metaproxy reload' in some cases would stop but not
682 start metaproxy - effectively stopping the service.
684 Don't display start log message when config testing (-t).
686 zoom: avoid CCL message limit of 1K in ZOOM filter.
688 --- 1.3.36 2012/05/10
690 metaproxy init script reacts to reload which does graceful stop +
691 start and is used by logrorate script.
693 --- 1.3.35 2012/05/09
695 Fixes for Windows compilation.
697 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
698 existing sessions running but terminate the monitor process that is
699 used in keepalive mode.
701 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
702 before. Consistent with 'metaproxy stop' message.
704 zoom: document zoom's proxy_timeout
706 z3950_client: fixup addinfo for init response
708 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
709 "Access to specified database denied" is returned, but only if init
710 response from backend does not carry diagnostics already.
712 multi: relays user info for first rejected target. The other-information
713 field for init response for first rejected target is in common init
714 response. This ensures that some backend init diagnostics are returned to
717 --- 1.3.34 2012/04/25
719 frontend_log: extend logging (when message is given in config).
721 --- 1.3.33 2012/04/25
723 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
725 --- 1.3.32 2012/04/24
727 sru_z3950 filter passes through incoming Z39.50 requests again. Was
728 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
730 --- 1.3.31 2012/04/24
732 zoom: fixes for retry/proxy failover logic. More logging.
734 --- 1.3.30 2012/04/23
736 zoom: return addinfo="proxy failure" for proxy failures. This also
737 changes the scheme for dealing with proxies a bit. zoom now always
738 do proxy check, even if there's no failover. Fortunately, that's not
741 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
742 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
743 generic. We don't know why the init would fail; IP, user, block IP, etc.
744 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
746 zoom: guess if invalid SRU response was an auth failure
748 session_shared: disable session retry by default . Can be enabled by
749 restart="true" in resultset section.
751 --- 1.3.29 2012/04/18
753 zoom: may read cf-proxy's config settings.
754 This reduces manual configuration of the content proxy server host.
755 The ZOOM module will use the old style session.proxyhost if "server"
756 is given (deprecated) and use the new style proxyhost/session if
757 "config_file" is in use.
759 frontend_net: remove incoming requests that can not be handled
760 Requests in queue for filter frontend_net are removed if client
761 closes connection for the session and request is not yet handled.
763 sru_z3950: serialize requests. This is to ensure that pipelined
764 HTTP requests are handled properly.
766 --- 1.3.28 2012/04/04
768 New class, wrbuf, that wraps YAZ' WRBUF.
770 --- 1.3.27 2012/03/30
772 Metaproxy daemon is now running as user "metaproxy". This user is
773 managed by package maintainer scripts. The user information is stored
774 in /etc/metaproxy/metaproxy.user .
776 --- 1.3.26 2012/03/20
778 New filter, sort, that allows sorting of XML records via Z39.50
781 Filter record_transform: USEMarcon support. For example:
782 <retrieval syntax="usmarc">
783 <backend syntax="unimarc" name="F">
784 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
788 Filter multi: empty route pattern uses route as default.
790 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
791 may use the shorter notation
792 <target route="z3950.indexdata.com"/>
794 Filter query_rewrite: use config path to locate XSLT.
796 Filter frontend_net: log statistics.
797 If a custom message element in frontend_net configuration it makes
798 the frontend_net filter produce a log entry whenever an operation
799 is completed. The log is always written using yaz_log with the
800 custom message given, the package ID (session ID) , the time
801 the operation has been active (end-to-end) , the threads currently
802 active/total and the size of the request input/output queues.
804 query_rewrite: charset conversion of query terms.
805 This is an optional feature. Enabled by element <charset> in
806 configuration with attribute 'from' and 'to' that specifies
807 from/to encodings. The default 'from' encoding is UTF-8.
809 Filter record_transform: honor piggyback searches.
811 Filter zoom: re-connect when database is reused.
812 Re-connect is necessary if a connection is lost or a timeout occurs.
813 If not, we'll be seeing zero hits, when we shouldn't.
815 --- 1.3.25 2012/02/29
817 zoom: Change scheme for dealing with content proxy URLs. The module
818 now has its own common XSL transform that is enabled by record_xsl
819 attribute in the configuration. This XSL gets parameter cproxyhost
820 that holds the host for the content proxy session . The genearted-url
821 is created only if urlRecipe is enabled. In previous version default
822 value of urlRecipe was ${md-electronic-url}; it is now empty and
823 disabled by default. Also generated-url no longer includes the content
824 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
827 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
828 connections. Default value is 40 (seconds).
830 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
831 "Malformed query" for syntax errors and related ones; throw
832 Bib-1: 3 "Unsupported search" for everything else. Details from
833 the CCL parser is provided as additional-info.
835 multi: new setting hideerrors that makes multi only relay diagnostics
836 to a client if all backends fail.
838 --- 1.3.24 2012/02/23
840 zoom: empty ccl_map field-mappings disables CCL map.
842 zoom: fix Explain search that could return error if session was
845 --- 1.3.23 2012/02/10
847 zoom: returns Explain records for database IR-Explain---1. The
848 target profile records are converted to Explain records via XSLT.
850 session_shared: make error recovery configurable. Whether a search
851 is restarted on errors or not, is configurable by attribute "restart"
852 in element "resultset" in configuration.
854 session_shared: only relay init for first request. session_shared, for
855 each backend class, now only relays first init request (rather than all).
856 The module only needs to save init response info once. This avoids the
857 need to check for session max.
859 --- 1.3.22 2012/02/02
861 zoom: fix memory leaks.
863 session_shared: maximum number of sessons is configurable. Default
864 value is 100. Result-sets for backends without named result sets are
865 only re-used if databases is identical for a search. This is under the
866 assumption that performance may suffer for those backends when
867 changing the database for each search.
869 multi: combines diagnostics from all backends. All diagnostics from
870 backends are combined into multiple non-surrogate diagnostics; rather
871 than just one diagnostic from first backend.
873 --- 1.3.21 2011/12/27
875 zoom: relay realm to cproxy parameter file.
877 Configuration: Allow filter collection element inside route. This
878 makes it possible to include multiple filters at once.
880 zoom: nocproxy also disables urlRecipe.
882 --- 1.3.20 2011/12/21
884 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
885 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
886 90: "Unsupported direction value".
888 zoom: honor database argument nocproxy. This disables creating a content
889 connector session (for non-CF targets, usually) and also relays nocproxy
890 as database argument to a CF target.
892 --- 1.3.19 2011/12/16
894 zoom: Multiple proxy hosts may be given for proxy rich database
895 parameter. List is comma separated.
897 http_file: decodes URI paths properly. Does not return 404: not found
898 if no prefix are matches. Instead packages are passed on.
900 --- 1.3.18 2011/12/08
902 zoom: content-{user,password,proxy} are passed on to content proxy
903 system and takes precedence over user,password,proxy .
905 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
906 with a log element including log material from children filters. At
907 this point, only the zoom filter uses this log facility. It will
908 eventually be used by other filters as well. In particular it might be
909 useful for this feature to track all filters in used during a search.
911 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
912 and queries as they are manipulated are logged.
914 zoom: extend addinfo with native diagnostics. Diagnostics as received
915 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
916 diagnostics. This indicates both a backend diagnostic and the original
919 zoom: default urlRecipe value is ${md-electronic-url}
921 zoom: target profile setting sruVersion is recognized.
923 --- 1.3.17 2011/11/17
925 zoom: log target profile record fetched (AKA Torus).
927 --- 1.3.16 2011/11/17
929 Change target profile parameter CfSubDb to CfSubDB.
931 --- 1.3.15 2011/11/12
933 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
934 makes sense to the zoom module itself).
936 --- 1.3.14 2011/11/11
938 zoom: realm may be given as part of database.
940 --- 1.3.13 2011/10/26
942 Fix Origin class assigment method; was removd by mistake in 1.3.12.
944 --- 1.3.12 2011/10/26
946 zoom: database args x-name=value are passed through to backend database.
948 SRU filter: user may specify session ID that is passed to log entries
949 that follows. It is specified by using x-session-id in the SRU arguments.
951 zoom: fix null pointer reference which would occur for bad url parameter
952 inside "torus" or if url was not given.
954 --- 1.3.11 2011/09/09
955 Fix bug in filter session_shared where sessions would not expire
956 properly (session ttl). This in turn could make the target close the
957 connection before expected and session_shared would return diagnostic
958 2: system temporarily available.
960 --- 1.3.10 2011/09/09
962 zoom: new target profile setting: sortmap_field. If sortmap_field is given
963 the field is mapped to the value for the sortmap. Values not matching
964 sortmap_field are passed verbatim.
966 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
967 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
968 depending on whether RPN or CQL is actually sent to the target.
972 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
974 zoom: For content proxy authentication is stored in param name
975 "auth", instead of "authentication".
979 zoom: relay schema in SRU mode. Previously recordSchema was not affected
984 zoom: new target profile element literalTransform that holds XSLT
985 (encoded as string) for target. Only if present and non-zero length it is
986 considered present. This takes precedence over transform.
988 Don't rely on trang anymore for Git checkout builds. Configuration in etc
989 will only be properly validated if trang is available. From now on only
990 relax NC files are bundled with the source dist.
992 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
993 component was not detected when it should be.
997 z3950_client: mark non-surrogate diagnostics from backend.
999 zoom: a proxy may be specified for HTTP fetch of target profiles.
1001 --- 1.3.4 2011/08/01
1003 Honor piggyback. Makes some SRU targets behave that insist on
1004 maximumRecords > 0, but also increases performance.
1006 --- 1.3.3 2011/08/01
1008 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
1009 file was not update for libdir/metaproxy4 in version 1.3.2.
1011 --- 1.3.2 2011/08/01
1013 Change location of Metaproxy modules from libdir/metaproxy to
1014 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
1015 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
1017 New facility to dump APDUs from zoom filter. Enabled by
1018 <log apdu="true"/> in the zoom filter configuation.
1020 zoom filter bug fix: SRU diagnostics received from backend was
1021 not properly converted to Bib-1 diagnostics.
1023 Package metaproxy depends on libmetaproxy4, same version.
1025 --- 1.3.1 2011/07/28
1027 zoom: fix a bug WRT passing authentication parameters to backends.
1029 --- 1.3.0 2011/07/27
1031 Fixes for windows Makefile.
1033 --- 1.2.10 2011/07/25
1035 Change major version of metaproxy library from 3 to 4. This in turn
1036 makes new package names for Debian and RPM.
1038 --- 1.2.9 2011/06/27
1040 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
1043 zoom: configurable element sets for record transforms.
1045 zoom: the target profile based transform is specified by element_transform
1046 in element torus of of the ZOOM filter configuration ; default value
1047 is "pz2". Target profile based retrieval is specified by element_raw
1048 in configuration. It will perform same steps, but omit the XSL transform.
1049 Default value is "raw".
1051 zoom: element set is omitted if not set in profile. But only if pz2
1052 transform is in effect. Previously the default element set was to "F".
1054 zoom: For non-CF targets database arguments are parsed. User may supply
1055 db,user=myuser&password=mypass for non-CF targets. These values override
1056 what's given the authentication from the target profile.
1058 session_shared: fix reference to freed memory. Would occur if a search
1059 response had non-surrogate diagnostics.
1061 --- 1.2.8 2011/06/22
1063 Route may be given for each port in frontend_net.
1065 --- 1.2.7 2011/06/22
1067 Documentation for zoom filter. Local target profiles may be specified.
1069 Fixes for zoom filter.
1071 --- 1.2.6 2011/06/15
1073 First version with zoom filter.
1075 --- 1.2.5 2011/05/06
1077 Filter z3950_client may be configured to always send a close APDU
1078 to backend target when connection/session is closed. This will only
1079 happen if close APDU is not already sent. Enabled by configuration
1080 for z3950_client (force_close).
1082 Filter virt_db and multi: relay close APDU.
1084 Filter virt_db and multi: relay init size parameters
1085 preferredMessageSize and maximumRecordSize.
1087 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
1089 --- 1.2.4 2011/01/27
1091 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
1093 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
1094 as determined by configure.
1096 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1097 this package can be distinguished from other vendors.
1099 --- 1.2.3 2010/10/04
1101 Fix filter multi: relay idAuthentication parameters.
1103 --- 1.2.2 2010/09/15
1105 Add metaproxy-config for returning compiler flags, libraries.
1107 --- 1.2.1 2010/08/18
1109 Fix --with-boost=PREFIX .
1111 --- 1.2.0 2010/07/09
1113 session_shared: fix use of maintenance thread.
1115 Introduce 'start' method for filters and routers. It gets called after
1116 configure and after fork, but before processing. This changes API -
1117 from libmetaproxy2 to libmetaproxy3.
1119 --- 1.1.7 2010/06/30
1121 session_shared: ensure backend session is closed if init rejected
1124 z3950_client: fix NULL ptr reference that could occur if two clients
1125 connected concurrently and if max-sockets was in effect.
1127 --- 1.1.6 2010/06/21
1129 Fix bug 3497 - Metaproxy unstable while stopping.
1131 Fix bug 3495 - SEGV in SRU filter.
1133 --- 1.1.5 2010/06/15
1135 Filter multi throws diagnostic 'Present Out of Range' when
1136 appropriate - rather than returning 0 records.
1138 Filter virt_db: fix bad result reuse. Could happen if a result
1139 was overriden and a backend did not supported named result sets.
1141 --- 1.1.4 2010/05/11
1143 Filter log: category access logs diagnostics even if searchStatus
1144 or presentStatus is 'success'.
1146 --- 1.1.3 2010/04/21
1148 The SRU to Z39.50 filter does repeated Z39.50 present requests
1149 to fetch all records. Needed when a Z39.50 server returns partial
1150 results (due to message size limits).
1152 --- 1.1.2 2010/03/18
1154 Metaproxy now kills all child processes that are spawned by
1155 modules (in case of fork, exec).
1157 --- 1.1.1 2010/01/28
1159 Debian package now installs /etc/metaproxy/metaproxy.xml which
1160 includes all XML files /etc/metaproxy/filters-enabled .
1161 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1163 --- 1.1.0 2010/01/20
1165 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1166 development package to facilitate 3rd party Metaproxy modules.
1168 --- 1.0.23 2010/01/04
1170 Filter virt_db: Close backend filter session when Init rejected is received
1171 from it (in which case it's not really closed yet). This will ensure we don't
1172 run out of resources such as FDs in this case.
1174 sru_z3950 filter: Accept any database (including those not listed).
1176 --- 1.0.22 2009/12/03
1178 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1179 later which means YAZ 3.0.47 or later.
1181 --- 1.0.20 2009/11/19
1183 For filter virt_db, the database is a glob pattern and the virtual
1184 database sections are consulted in the order given.
1186 --- 1.0.19 2009/07/08
1188 For filter multi, the target (for routing) may be given as a glob-pattern.
1190 More documentation for filters virt_db and multi.
1192 Update schema to allow for no database in sru_z3950 filter.
1194 --- 1.0.18 2009/06/30
1196 Added limit filter to put sleep (penalty) for heavy use.
1198 Filter frontend_net may be configured to limit the number of new connections
1199 from same IP to some value (connect-max).
1201 Fixed the load_balance filter.
1203 --- 1.0.17 2009/06/16
1205 Fix path for metaproxy executable for Debian init.d script.
1207 --- 1.0.16 2009/06/10
1209 SRU to Z39.50 filter honors x-username and x-password. If only
1210 x-username is given that translates to open authentication (Z39.50v2). If
1211 both x-username and x-password is present that translates to idPass
1212 authentication (Z39.50v3).
1214 New facility to change current working directory (-w).
1216 Update to upstream skeleton of init.d script. Should fix bug #2619.
1218 Filter session_shared now caches records (used to only cache connections
1221 Filter session_shared now invalidates a Z39.50 session if a server
1222 returns -1 hits. This facility was also part of yazproxy and gets around
1223 a bug in Voyager-based Z39.50 servers.
1225 --- 1.0.15 2008/11/18
1227 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1229 --- 1.0.14 2008/06/09
1231 Fixed the value of SRU record schema in searchRetrieve response. It was set
1232 to a fixed value of "dc" before.
1234 Serialize identical SRU requests. This is useful if HTTP client software
1235 fires identical requests against metaproxy.
1237 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1238 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1239 avoid static configuration. This facility is handled by the sru_z3950 module
1240 and the z3950_client module.
1242 Allow maximum number of sockets to be used for a Z39.50 client by the
1243 use of SRU extra parameter x-max-sockets. This facility is handled by the
1244 sru_z3950 module and the z3950_client module.
1246 --- 1.0.13.1 2008/02/29
1248 Simplified check for Boost libraries.
1250 --- 1.0.13 2008/02/29
1252 First Debian package.
1254 The sru_z9350 filter now recognizes SRU parameter z-target as being
1255 a ZURL of the form host/database .
1257 Mergetype may be specified for filter 'multi'.
1259 --- 1.0.12 2007/09/19
1261 Fixed problem in Makefile WRT library specifictions. This could produce
1262 linker errors (when they should not happen).
1264 Fixed bug #1341: MetaProxy returning different results. Problem was that
1265 fix-up of record database did not normalize the database name.
1267 Documentation updates for Windows compilation.
1269 --- 1.0.11 2007/06/14
1271 Fixed problem with logfile being truncated.
1273 --- 1.0.10 2007/05/23
1275 Fixed bug #1136: Access rights not enforced.
1277 Extension for log module. The log category 'access' logs more details.
1278 New category 'user-access' added which is simlar to 'access' but adds
1279 the Z39.50 user as for all entries in a session.
1283 Added support for configurable default/force target/vhost for module Z39.50
1286 --- 1.0.8 2007/01/25
1288 Implemented filter, session_shared, which optimizes usage of Z39.50
1289 sessions and result sets.
1291 New filter, record_transform, which converts MARC/XML records.
1293 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1295 New filter, load_balance, in development.
1297 New filter, zeerex_xplain.
1299 XML framework for config files started.
1301 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1302 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1303 XML config files are checked against RNG and XML Schema's.
1305 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1306 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1307 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1308 explain record to YAZ CQL-to-PQF text config file.
1310 --- 1.0.7 2006/11/07
1312 Added 'timeout' setting for filter frontend_net which specifies the number
1313 of seconds a session is idle before it is closed. Default timeout is
1316 --- 1.0.6 2006/07/07
1318 Database name in records returned set for virt_db/multi filters.
1320 Filter session_shared now functional.
1322 Log filter can be configured to write to a given file using 'filename'
1323 element. Also information category can be specified with 'category'. If
1324 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1327 --- 1.0.5 2006/05/16
1329 Fixed compilation on Windows.
1331 --- 1.0.4 2006/05/16
1333 Added documentation for the hidenavailable option for the multi filter.
1335 --- 1.0.3 2006/05/16
1337 Fixed bug #573: Hide errors for individual servers. If the element
1338 'hideunavailable' is given in the configuration, individual servers
1339 being unavailable are hidden (unless all are unavailable).
1341 Fixed bug #574: Database names are recognised case-sensitively.
1343 Fixed bug #567: Fix up database name in Name-Plus-Record.
1345 Fixed bug #568: Update win/makefile for VS 2005.
1347 Fixed bug #569: Some options throws unknown exception.
1349 --- 1.0.2 2006/04/28
1351 More information about virtual hosts. The 'etc' directory is part of the
1354 --- 1.0.1 2006/04/27
1356 Build instructions for Windows. NMake makefile part of distribution tar.
1358 --- 1.0.0 2006/04/24
1362 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1363 log, multi, query_rewrite, template, virt_db, z3950_client.
1365 Filters in development: session_shared.
1367 Pseudo-filters: template, dl
