16 Update to debhelper 9 MP-622
20 Fix incorrect diagnostic for reverse cql2pqf MP-619
21 The cql_transform_rpn2cql_stream_r returns Bib-1 diagnostics; not
24 deb: deprecated substitution ${Source-Version} MP-621
26 Fix systemd: reload stops metaproxy MP-620
27 Detect systemd and just do nothing when reload/force-reload is
28 used. Log, however, that it really is not reloading.
30 Add http-req-max to frontend_net MP-617
34 Fix multi: hideunavailable don't hide target that timeout MP-615
38 Fix race condition in MP log output MP-522
40 Fix 'Group' is duplicated twice in RPM spec
42 Fix crash in log filter when record syntax is omitted MP-613
44 Change target z3950.loc.gov:7090/voyager -> lx2.loc.gov:210/LCDB_MARC8
47 Fix Control-C does not stop Metaproxy spawned by shell MP-610
48 Check for fork mode instead (-D) - rather than debug (-X)
52 sru_z3950: allow CCL in SRU search MP-606
53 Makes the sru_z3950 filter convert to CCL queries if query type
54 "ccl" is used, eg ?query=water&queryType=ccl&... for SRU 2.0.
58 Fix dead lock in session_shared (init) MP-605
62 Fix session_shared caches set with diagnostic MP-604
64 Fix assertion failed in session_shared filter MP-603
66 Make /usr/share/metaproxy be part of metaproxy RPM MP-601
68 Log YAZ version upon start MP-599
72 sru_z3950: undo Serialize identical SRU GET requests MP-598
73 Now much more elegantly handled by session_shared.
75 session_shared: anticipated init and search MP-597
77 z3950_client: separate init timeout MP-596
78 Both init-timeout and connect-timeout are configurable by this change.
79 Default is 10 seconds.
83 zoom: support cf_-params MP-595
85 http_client: returns 404 if no destination URI is given
89 zoom: allow / in user and password db args MP-592
93 Log rotate no longer reloads configuration - instead Metaproxy just
94 re-opens log files when SIGHUP is received. MP-485
96 Debian : init.d metaproxy reload should check configuration MP-591
98 Fix Metaproxy stops logging after check config failed MP-590
102 Fix double free in log filter (with incorrect config) MP-589
104 zoom: Add allow_ip feature - fixes MP-588
105 Allow a list of IPs to be given separated by blanks
106 <allow auth_url="http://mkc-admin.indexdata.com/..."
107 allow_ip="127.0.0.1 ::1" .. >
109 cql2pqf.txt: Maps dc.subject to Bib-1 21 rather than 47

119 Destroy router and filters in parent process MP-584
121 Update NMAKE makefile to use Visual Studio 2013 along with Boost 1.57,
122 ICU 54.1, Libxml2 2.9.2, Libxslt 1.1.28.
126 Use YAZ backtrace facility MP-582
128 Fix libmetaproxy-dev depends on libgnutls-dev - MP-580
129 libgnutls-dev is unavailable on jessie.
131 Update template filter to avoid Pimpl MP-579
133 cgi: POSTed content - part of MP-562
135 Fix filter cgi does not relay session close MP-577
139 Add support for binding outgoing IP for http_client and z3950_client
140 This is enabled by bind_host setting. MP-575
144 z3950_client: allows negotiation charset to be set MP-574
146 cgi: more functional but no support for POSTed content yet (part of MP-564)
148 --- 1.5.11 2014/10/20
150 http_file: add include of sys/stat.h fixes MP-576
152 Fix documentation about SRU client support MP-572
154 Initialize Libxml2 - for threaded operation MP-571
156 --- 1.5.10 2014/08/26
158 On SIGTERM shut down connection+listening sockets MP-568
159 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
163 zoom: make retry on failure configurable MP-565
164 The default and existing behavior is that backend failures (any
165 diagnostic) makes the module re-search once. The behavior may
166 be changed by db parameter 'retry'. If given value '0' disables
167 retry and '1' enables it. If not given, the Torus record may
168 specify with element retryOnFailure (value '0'/'1').
172 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
173 instead of just a child process. Extremely rare in real life, hit me with
174 CF stress testing. MP-559.
178 http_file: passthru option MP-557
179 New facility for http_file to passthru - even if an area is matched. The
180 default behavior (passthru=false) is to return 404: Not found. With
181 passthru=false, next filter is consulted.
185 Fix ref to freed memory in log filter 1line - MP-556
187 echoedSearchRetrieveRequest support MP-555
191 zoom: allow hostname to be given for ipauth MP-552
192 The Torus setting for that is called auth_hostname.
196 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
200 session_shared: close in ~BackendInstance MP-549
201 This fixes a serious issue where some MP would leak sockets.
203 session_shared: mutex lock in BackendClass::release_backend MP-550
204 Fixes a SEGV that could occur (in rare cases).
208 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
210 zoom: fix invalid present response in some cases MP-546
212 zoom: Relay Torus HTTP error message
216 Check for proper limits before using RecordCache functions MP-544
220 Build packages for Ubuntu Trusty Tahr 14.04 LTS
222 sort: crash / invalid_read in filter sort MP-541
224 sru_z3950: facet should be stored in additionalSearchInfo MP-533
226 doc: fix missing man pages MP-542
228 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
230 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
234 sru_z3950: fix facet response (memory corruption) MP-532
236 log: fix crash idPass user is omitted MP-530
240 query_rewrite: pass-thru non Type-1 queries MP-527
242 metaproxy stop (SIGTERM) kills all child processes spanwed by
243 filter (if any) before invoking filter destructors. MP-525
247 http_file: only supports HTTP GET MP-523
249 session_shared: shut down expire thread in destructor
250 This ensures that expire thread is not running after destruction
251 and does bad memory references, etc.
253 frontend_net: fix segfault on startup MP-524
254 Would happen if MP was listening on multiple ports and one
255 of the ports was already in use (and MP would exit).
257 frontend_net: fix memory leak MP-521
258 This leak would occur if all sessions were in use and the input
259 queue was cleared when a client would close connection (socket).
261 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
265 http_rewrite: use local skiplist; fixes memory corruption. MP-520
267 http_client: x-forwarded-for controls X-Forwarded-For presence
268 If x-forwarded-for setting (boolean) is enabled, http_client will
269 generate an X-Forwarded-For header entry which includes existing
270 X-Forwarded-For (if any) and current peer address (immediate client
271 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
272 will not be generated.
274 z3950_client: client_ip controls client-IP presence
275 If client_ip setting (boolean) is enabled, z3950_client will
276 generate a client_ip OID as part of init request which includes
277 previous client_ip (if any) and current peer address (immediate
278 client of Metaproxy). By default client_ip is disabled and client_ip
279 will not be generated.
281 HTTP X-Forwarded-For/Z39.50 Client-IP support
282 virt_db, multi: relays Z39.50 client-IP.
283 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
284 zoom: uses Client-IP or origin address (prefer Client-IP).
285 frontend_net: Strips tcp: from peer address (so that it is no longer
286 printed and stripped in zoom filter).
287 z3950_client: builds client-IP list - combining immediate peer address
288 as returned by COMSTACK and existing client-IP list (if avaiable).
289 The Origin only printes first X-Forwarded address.
293 Log when SIG{TERM,USR1} is received ASAP MP-513
294 Do it in frontend_net event loop rather than in place for metaproxy
295 main, which only exits when all sessions are terminated for SIGUSR1
298 metaproxy-config: quote some RHS values (that might include blanks)
300 Fix leak in sru_z3950 filter - when explain is returned MP-511
302 Allow stylesheet to be given for sru_z3950 filter MP-510
303 This is based on a patch by Sven Porst and the functionality
304 of the YAZ Generic Frontend Server.
306 Allow base attribute in configuration file tags - the attributes are
307 inserted by XInclude usage as mentioned on
308 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
309 and noted in a gist: https://gist.github.com/3551094
311 Package metaproxy provides virtual package metaproxy6 MP-508
312 This allows module packages to depend on a metaproxy server
315 Filter destructors called upon daemon termination MP-505
316 When metaproxy daemon receives SIGTERM the stop method of each filter
317 is called. The stop method existed before, but did not take any
318 arguements (void).. The frontend_net filter can now distinguish
319 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
320 (stop immediately). Note that this changes the API+ABI of Metaproxy
323 zoom: sync up with Pazpar2 WRT authentication handling MP-492
325 Router: use shared_ptr rather than naked one - to avoid leak if an
326 exception is thrown in configure.
330 zoom: Add nocproxy=1 for contentConnector sessions MP-501
332 Doc: mention proper versions; fix link to Boost win binaries.
334 Windows: update for Boost 1.55
336 Windows: avoid warning when using boost::split. Done by defining
337 _SCL_SECURE_NO_WARNINGS for Visual Studio.
339 Fix LSB conformance for /etc/init.d/metaproxy MP-500
340 Debian: add support for /etc/init.d/metaproxy status
342 sort: Add const to Record less than operator in order to compile on
347 session_shared: fix element-set handling in record caching. MP-499
349 document http_rewrite. MP-468
351 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
352 respects the header (which will normally come from the cproxy filter)
356 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
357 RPM was unsable in version 1.4.0.
359 Remove log message about "backend classes". Appeared in version 1.4.0.
363 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
364 with older version from source, but packages now use YAZ 5 that supports
367 sru_z3950: Fix SEGV for decoding invalid SRU requests
368 Incorrect reference to union (was explain response rather than
371 session_shared: match additionalSearchInfo (includes facets). In
372 layman's terms means that means that facets are properly handled
373 by this filter. Eg a change in requested facets will issue new
374 search and facets from exisiting result set are cached.
376 --- 1.3.62 2013/09/11
378 http_rewrite: better handling of <script> content in HTML parser. MP-486
380 http_rewrite: fix threading issue with regex. MP-482
382 bounce: don't use strdup for fixed length content. Error occurred in echo
385 session_shared: expire backend class when no instances left. This
386 means memory clean up, but not really a leak fix.
388 virt_db: fix leak for naked ptr.
390 cql_rpn: use config relative path for cql2rpn file. MP-481
392 Updates for upcoming YAZ 5.
394 --- 1.3.61 2013/08/29
396 New configuration directories ports.d/routes.d for metaproxy
397 configuration. This allows 3rd party packages to install config
398 for ports and new routes. MP-477
400 --- 1.3.60 2013/08/21
402 Fix metaproxy-config --libs to return non-mt over mt libs.
403 The -mt versions do not exist as shared objects and cause
404 linker errors for applications linking with Metaproxy.
405 Problem present in versions 1.3.56 - 1.3.59. MP-475
407 HTML: clean up char checks. Add ptr to HTML parse spec
409 HTML parser stops eating tag when <-char is met MP-473
411 rewrite: do not even compare content types, if we don't have any
412 the regex_match caused a segfault if we had no content-type in the
415 rewrite: within header=... matches only the header value
416 Used to match the whole header line, but we need to use
417 ^$ anchoring for host-relative regexps, and they need to
418 anchor at the ends of the value. MP-470.
420 rewrite: Ruleset functional MP-469
422 --- 1.3.59 2013/07/12
424 session_shared: negotiate init sz parameters.
425 By default, session_shared will honor the paramters given by client.
426 An alternative, but not implemented, algorithm would be to only
427 re-use sessions with same sz parameters. This however, could reduce
428 re-use of sessions a lot. Hence this, simple algorithm instead. The
429 negotiation to a maximum sz values can be enabled by using
430 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
431 in configuration. This will make session_shared send those values
432 to backends and use returned init values in negotaition to
433 client before session_shared.
435 session_shared: resolve result-set references.
436 The reference is substitued with the query for old set if database
437 match and query type is Type-1. If not the reference will issue a
440 sort filter: relays RecordComposition including elementSet in use for
443 http_client: better diagnostics
445 http_client: disables HTTP redirect handling by default.
446 It can be configured with max-redirects in configuration.
448 --- 1.3.58 2013/06/12
450 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
452 --- 1.3.57 2013/06/12
454 Make RouterChain and RouterXML part of public API (libmetaproxy).
456 http_client: honor X-Metaproxy-Proxy as an alternative to
457 the "proxy" configuration. Allows proxy to be set per HTTP request.
459 sru_z3950: For SRU requests recognize x-client prefixes as a way
460 to ingest "database parameters".. The suffix of x-client- serves
461 as database argument name. Multiple may be given. For example:
462 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
463 is turned into Z39.50 database
466 --- 1.3.56 2013/05/27
468 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
470 New filter sd_remove, which replaces surrogate diagnostics with
471 SUTRS records. This filter tries to deal with clients that breaks
472 when receiving surrogate diagnostics.
474 new filter http_client. Same role as z3950_client, but just for
475 HTTP. Allows Metaproxy to operate as a HTTP proxy.
477 New filter http_rewrite1, which serves as purpose on how to rewrite
478 HTTP content with Metaproxy.
480 Use libboost-system if available, because newer versions of libboost-threads
481 requires libboost-system.
483 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
486 --- 1.3.55 2013/04/10
488 zoom: Torus setting: authenticationMode which may hold values "basic"
491 --- 1.3.54 2013/03/27
493 configure: check for Libxslt support in YAZ and rely on definitions
494 from yaz-config, rather than doing own xslt/xml2 checks.
496 Allow timestamp format for log lines to be given with option -m
497 for metaproxy. Similar to yaz-ztest/GFS option -m.
499 Document log category 'line' for log filter.
501 Solr configuration example in etc/config-solr.xml
503 multi: do not mess with request package. For scan and search,
504 database-names were modified and the request package was left with
505 dangling pointers that caused a log filter to fail (request package
506 inspected after multi was invoked).
508 Documentation: fix id of metaproxy-config ref .
510 Documentation: update for USEMARCON support.
512 --- 1.3.53 2013/01/31
514 record_transform: allow OPACXML to OPAC conversion
516 zoom: document content-proxy
518 zoom: document db parm content-{user,password}, torus_url. Also
519 <torus auth_url="..> which makes zoom operate in authenticated mode
522 --- 1.3.52 2012/11/30
524 zoom: fix http://-check. SRU search broken in 1.3.51.
526 --- 1.3.51 2012/11/15
528 zoom: only append http:// for SRU if not already given . Makes it
529 possible to use https-URLs.
531 Use yazpp 1.4 or later due to new ABI.
533 frontend_net: allow max package size to be specified. Controlled by
534 attribute 'max_recv_bytes' of element 'port'.
536 --- 1.3.50 2012/10/29
538 For most generated diagnostics by filters, typically temporary
539 system error, augment addinfo message with filter name.
541 Add support for CentOS 6 packages.
543 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
545 Add man page for metaproxy-config.
547 --- 1.3.49 2012/10/18
549 zoom: new config element passthru. This defines an element set that is
550 passed verbatim to the backend in pz2 mode.
552 auth_simple: allow both idPass and open auth. Also fix SEGV that could
555 --- 1.3.48 2012/10/08
557 z3950_client: fix string handling for init diagnostics in the case where
560 query_rewrite: no charset conversion for error queries. Avoid performing
561 charset conversion for query conversion errors. The resulting Type-1
562 query is invalid in this case.
564 --- 1.3.47 2012/10/04
566 For graceful stop (SIGUSR1), metaproxy will kill children processes.
568 Log when metaproxy is invoked in test mode (-t).
570 Log PID for each log message.
572 multi: combine both NSDs and multiple NSDs into one (diagnostics).
574 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
575 a (backend=target) is appended for each diagnostic so that can be
576 determined the origin of error.
578 multi: hideerrors also in use for present response.
580 Solr example in zoom man page.
582 Fix typo in query_rewrite config example.
584 Log at least first non surrogate diagnostic. Instead of
585 "Z_Records_multipleNSD"
587 multi: Fix check for opt Records in present response. A SEGV could occur
588 if a target did not return records and no diagnostics.
590 --- 1.3.46 2012/09/24
592 Yet another fix for graceful stop.
594 --- 1.3.45 2012/09/12
596 sru_z3950: relay surrogate diagnostics.
598 --- 1.3.44 2012/09/10
600 zoom: Honor extraArgs, strip # in zurl.
602 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
604 zoom: url_recipe allow %{var[reg]} substitutions.
605 It's like ${var[reg]} but does URI component encoding as well.
607 --- 1.3.43 2012/08/22
609 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
610 non-keepalive HTTP sessions.
612 http_file: allow zero size files (bug fix)
614 Fix zoom schema: auth_url is optional
616 --- 1.3.42 2012/08/20
618 zoom: fix un-init memory (could result in SEGV at session close)
620 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
621 and may be used in filters as usual.
623 zoom: authentication via Torus lookup
624 Enabled by new configuration setting: auth_url . If this is defined,
625 the zoom module will contact Torus for auth/IP lookup and that will
626 define realm to be used in session.
628 --- 1.3.41 2012/08/10
630 virt_db: Fix database name - first character we removed by mistake.
631 Bug introduced in 1.3.40.
633 --- 1.3.40 2012/08/06
635 virt_db: Don't use "unix path" as database for Unix sockets.
637 --- 1.3.39 2012/08/02
639 z3950_client: Don't tamper with / in zurl - fixes problems
640 using Unix sockets for backends.
642 session_shared: fix integer overflow problem with hit count.
644 session_shared: avoid long usage of cached queries.
646 zoom: New database argument , torus_url to set URL of Torus
647 record to be fetched.
649 --- 1.3.38 2012/07/04
651 Fixes for 'metaproxy reload' for RPM/Debian packages.
653 zoom: Allow rpn2cql conversion to be augmented with a properties file.
654 Element rpn2cql can be specified per-target for the zoom filter.
656 log: New category "line" which is a single-line log message with
657 most important parts of a HTTP/Z39.50 request/response.
659 --- 1.3.37 2012/06/01
661 frontend_net: add facility to report live statistics about response
662 times and current thread usage. The report is an XML document
663 and is triggered for a specific URL path. This is set by <stat-req>
664 in the configuration of frontend_net. By default this report is
665 disabled (same as empty value for <stat-req>).
667 Fix reload problem in init.d script for RPM/Debian.
668 The '/etc/init.d/metaproxy reload' in some cases would stop but not
669 start metaproxy - effectively stopping the service.
671 Don't display start log message when config testing (-t).
673 zoom: avoid CCL message limit of 1K in ZOOM filter.
675 --- 1.3.36 2012/05/10
677 metaproxy init script reacts to reload which does graceful stop +
678 start and is used by logrorate script.
680 --- 1.3.35 2012/05/09
682 Fixes for Windows compilation.
684 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
685 existing sessions running but terminate the monitor process that is
686 used in keepalive mode.
688 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
689 before. Consistent with 'metaproxy stop' message.
691 zoom: document zoom's proxy_timeout
693 z3950_client: fixup addinfo for init response
695 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
696 "Access to specified database denied" is returned, but only if init
697 response from backend does not carry diagnostics already.
699 multi: relays user info for first rejected target. The other-information
700 field for init response for first rejected target is in common init
701 response. This ensures that some backend init diagnostics are returned to
704 --- 1.3.34 2012/04/25
706 frontend_log: extend logging (when message is given in config).
708 --- 1.3.33 2012/04/25
710 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
712 --- 1.3.32 2012/04/24
714 sru_z3950 filter passes through incoming Z39.50 requests again. Was
715 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
717 --- 1.3.31 2012/04/24
719 zoom: fixes for retry/proxy failover logic. More logging.
721 --- 1.3.30 2012/04/23
723 zoom: return addinfo="proxy failure" for proxy failures. This also
724 changes the scheme for dealing with proxies a bit. zoom now always
725 do proxy check, even if there's no failover. Fortunately, that's not
728 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
729 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
730 generic. We don't know why the init would fail; IP, user, block IP, etc.
731 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
733 zoom: guess if invalid SRU response was an auth failure
735 session_shared: disable session retry by default . Can be enabled by
736 restart="true" in resultset section.
738 --- 1.3.29 2012/04/18
740 zoom: may read cf-proxy's config settings.
741 This reduces manual configuration of the content proxy server host.
742 The ZOOM module will use the old style session.proxyhost if "server"
743 is given (deprecated) and use the new style proxyhost/session if
744 "config_file" is in use.
746 frontend_net: remove incoming requests that can not be handled
747 Requests in queue for filter frontend_net are removed if client
748 closes connection for the session and request is not yet handled.
750 sru_z3950: serialize requests. This is to ensure that pipelined
751 HTTP requests are handled properly.
753 --- 1.3.28 2012/04/04
755 New class, wrbuf, that wraps YAZ' WRBUF.
757 --- 1.3.27 2012/03/30
759 Metaproxy daemon is now running as user "metaproxy". This user is
760 managed by package maintainer scripts. The user information is stored
761 in /etc/metaproxy/metaproxy.user .
763 --- 1.3.26 2012/03/20
765 New filter, sort, that allows sorting of XML records via Z39.50
768 Filter record_transform: USEMarcon support. For example:
769 <retrieval syntax="usmarc">
770 <backend syntax="unimarc" name="F">
771 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
775 Filter multi: empty route pattern uses route as default.
777 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
778 may use the shorter notation
779 <target route="z3950.indexdata.com"/>
781 Filter query_rewrite: use config path to locate XSLT.
783 Filter frontend_net: log statistics.
784 If a custom message element in frontend_net configuration it makes
785 the frontend_net filter produce a log entry whenever an operation
786 is completed. The log is always written using yaz_log with the
787 custom message given, the package ID (session ID) , the time
788 the operation has been active (end-to-end) , the threads currently
789 active/total and the size of the request input/output queues.
791 query_rewrite: charset conversion of query terms.
792 This is an optional feature. Enabled by element <charset> in
793 configuration with attribute 'from' and 'to' that specifies
794 from/to encodings. The default 'from' encoding is UTF-8.
796 Filter record_transform: honor piggyback searches.
798 Filter zoom: re-connect when database is reused.
799 Re-connect is necessary if a connection is lost or a timeout occurs.
800 If not, we'll be seeing zero hits, when we shouldn't.
802 --- 1.3.25 2012/02/29
804 zoom: Change scheme for dealing with content proxy URLs. The module
805 now has its own common XSL transform that is enabled by record_xsl
806 attribute in the configuration. This XSL gets parameter cproxyhost
807 that holds the host for the content proxy session . The genearted-url
808 is created only if urlRecipe is enabled. In previous version default
809 value of urlRecipe was ${md-electronic-url}; it is now empty and
810 disabled by default. Also generated-url no longer includes the content
811 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
814 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
815 connections. Default value is 40 (seconds).
817 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
818 "Malformed query" for syntax errors and related ones; throw
819 Bib-1: 3 "Unsupported search" for everything else. Details from
820 the CCL parser is provided as additional-info.
822 multi: new setting hideerrors that makes multi only relay diagnostics
823 to a client if all backends fail.
825 --- 1.3.24 2012/02/23
827 zoom: empty ccl_map field-mappings disables CCL map.
829 zoom: fix Explain search that could return error if session was
832 --- 1.3.23 2012/02/10
834 zoom: returns Explain records for database IR-Explain---1. The
835 target profile records are converted to Explain records via XSLT.
837 session_shared: make error recovery configurable. Whether a search
838 is restarted on errors or not, is configurable by attribute "restart"
839 in element "resultset" in configuration.
841 session_shared: only relay init for first request. session_shared, for
842 each backend class, now only relays first init request (rather than all).
843 The module only needs to save init response info once. This avoids the
844 need to check for session max.
846 --- 1.3.22 2012/02/02
848 zoom: fix memory leaks.
850 session_shared: maximum number of sessons is configurable. Default
851 value is 100. Result-sets for backends without named result sets are
852 only re-used if databases is identical for a search. This is under the
853 assumption that performance may suffer for those backends when
854 changing the database for each search.
856 multi: combines diagnostics from all backends. All diagnostics from
857 backends are combined into multiple non-surrogate diagnostics; rather
858 than just one diagnostic from first backend.
860 --- 1.3.21 2011/12/27
862 zoom: relay realm to cproxy parameter file.
864 Configuration: Allow filter collection element inside route. This
865 makes it possible to include multiple filters at once.
867 zoom: nocproxy also disables urlRecipe.
869 --- 1.3.20 2011/12/21
871 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
872 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
873 90: "Unsupported direction value".
875 zoom: honor database argument nocproxy. This disables creating a content
876 connector session (for non-CF targets, usually) and also relays nocproxy
877 as database argument to a CF target.
879 --- 1.3.19 2011/12/16
881 zoom: Multiple proxy hosts may be given for proxy rich database
882 parameter. List is comma separated.
884 http_file: decodes URI paths properly. Does not return 404: not found
885 if no prefix are matches. Instead packages are passed on.
887 --- 1.3.18 2011/12/08
889 zoom: content-{user,password,proxy} are passed on to content proxy
890 system and takes precedence over user,password,proxy .
892 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
893 with a log element including log material from children filters. At
894 this point, only the zoom filter uses this log facility. It will
895 eventually be used by other filters as well. In particular it might be
896 useful for this feature to track all filters in used during a search.
898 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
899 and queries as they are manipulated are logged.
901 zoom: extend addinfo with native diagnostics. Diagnostics as received
902 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
903 diagnostics. This indicates both a backend diagnostic and the original
906 zoom: default urlRecipe value is ${md-electronic-url}
908 zoom: target profile setting sruVersion is recognized.
910 --- 1.3.17 2011/11/17
912 zoom: log target profile record fetched (AKA Torus).
914 --- 1.3.16 2011/11/17
916 Change target profile parameter CfSubDb to CfSubDB.
918 --- 1.3.15 2011/11/12
920 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
921 makes sense to the zoom module itself).
923 --- 1.3.14 2011/11/11
925 zoom: realm may be given as part of database.
927 --- 1.3.13 2011/10/26
929 Fix Origin class assigment method; was removd by mistake in 1.3.12.
931 --- 1.3.12 2011/10/26
933 zoom: database args x-name=value are passed through to backend database.
935 SRU filter: user may specify session ID that is passed to log entries
936 that follows. It is specified by using x-session-id in the SRU arguments.
938 zoom: fix null pointer reference which would occur for bad url parameter
939 inside "torus" or if url was not given.
941 --- 1.3.11 2011/09/09
942 Fix bug in filter session_shared where sessions would not expire
943 properly (session ttl). This in turn could make the target close the
944 connection before expected and session_shared would return diagnostic
945 2: system temporarily available.
947 --- 1.3.10 2011/09/09
949 zoom: new target profile setting: sortmap_field. If sortmap_field is given
950 the field is mapped to the value for the sortmap. Values not matching
951 sortmap_field are passed verbatim.
953 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
954 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
955 depending on whether RPN or CQL is actually sent to the target.
959 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
961 zoom: For content proxy authentication is stored in param name
962 "auth", instead of "authentication".
966 zoom: relay schema in SRU mode. Previously recordSchema was not affected
971 zoom: new target profile element literalTransform that holds XSLT
972 (encoded as string) for target. Only if present and non-zero length it is
973 considered present. This takes precedence over transform.
975 Don't rely on trang anymore for Git checkout builds. Configuration in etc
976 will only be properly validated if trang is available. From now on only
977 relax NC files are bundled with the source dist.
979 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
980 component was not detected when it should be.
984 z3950_client: mark non-surrogate diagnostics from backend.
986 zoom: a proxy may be specified for HTTP fetch of target profiles.
990 Honor piggyback. Makes some SRU targets behave that insist on
991 maximumRecords > 0, but also increases performance.
995 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
996 file was not update for libdir/metaproxy4 in version 1.3.2.
1000 Change location of Metaproxy modules from libdir/metaproxy to
1001 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
1002 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
1004 New facility to dump APDUs from zoom filter. Enabled by
1005 <log apdu="true"/> in the zoom filter configuation.
1007 zoom filter bug fix: SRU diagnostics received from backend was
1008 not properly converted to Bib-1 diagnostics.
1010 Package metaproxy depends on libmetaproxy4, same version.
1012 --- 1.3.1 2011/07/28
1014 zoom: fix a bug WRT passing authentication parameters to backends.
1016 --- 1.3.0 2011/07/27
1018 Fixes for windows Makefile.
1020 --- 1.2.10 2011/07/25
1022 Change major version of metaproxy library from 3 to 4. This in turn
1023 makes new package names for Debian and RPM.
1025 --- 1.2.9 2011/06/27
1027 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
1030 zoom: configurable element sets for record transforms.
1032 zoom: the target profile based transform is specified by element_transform
1033 in element torus of of the ZOOM filter configuration ; default value
1034 is "pz2". Target profile based retrieval is specified by element_raw
1035 in configuration. It will perform same steps, but omit the XSL transform.
1036 Default value is "raw".
1038 zoom: element set is omitted if not set in profile. But only if pz2
1039 transform is in effect. Previously the default element set was to "F".
1041 zoom: For non-CF targets database arguments are parsed. User may supply
1042 db,user=myuser&password=mypass for non-CF targets. These values override
1043 what's given the authentication from the target profile.
1045 session_shared: fix reference to freed memory. Would occur if a search
1046 response had non-surrogate diagnostics.
1048 --- 1.2.8 2011/06/22
1050 Route may be given for each port in frontend_net.
1052 --- 1.2.7 2011/06/22
1054 Documentation for zoom filter. Local target profiles may be specified.
1056 Fixes for zoom filter.
1058 --- 1.2.6 2011/06/15
1060 First version with zoom filter.
1062 --- 1.2.5 2011/05/06
1064 Filter z3950_client may be configured to always send a close APDU
1065 to backend target when connection/session is closed. This will only
1066 happen if close APDU is not already sent. Enabled by configuration
1067 for z3950_client (force_close).
1069 Filter virt_db and multi: relay close APDU.
1071 Filter virt_db and multi: relay init size parameters
1072 preferredMessageSize and maximumRecordSize.
1074 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
1076 --- 1.2.4 2011/01/27
1078 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
1080 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
1081 as determined by configure.
1083 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1084 this package can be distinguished from other vendors.
1086 --- 1.2.3 2010/10/04
1088 Fix filter multi: relay idAuthentication parameters.
1090 --- 1.2.2 2010/09/15
1092 Add metaproxy-config for returning compiler flags, libraries.
1094 --- 1.2.1 2010/08/18
1096 Fix --with-boost=PREFIX .
1098 --- 1.2.0 2010/07/09
1100 session_shared: fix use of maintenance thread.
1102 Introduce 'start' method for filters and routers. It gets called after
1103 configure and after fork, but before processing. This changes API -
1104 from libmetaproxy2 to libmetaproxy3.
1106 --- 1.1.7 2010/06/30
1108 session_shared: ensure backend session is closed if init rejected
1111 z3950_client: fix NULL ptr reference that could occur if two clients
1112 connected concurrently and if max-sockets was in effect.
1114 --- 1.1.6 2010/06/21
1116 Fix bug 3497 - Metaproxy unstable while stopping.
1118 Fix bug 3495 - SEGV in SRU filter.
1120 --- 1.1.5 2010/06/15
1122 Filter multi throws diagnostic 'Present Out of Range' when
1123 appropriate - rather than returning 0 records.
1125 Filter virt_db: fix bad result reuse. Could happen if a result
1126 was overriden and a backend did not supported named result sets.
1128 --- 1.1.4 2010/05/11
1130 Filter log: category access logs diagnostics even if searchStatus
1131 or presentStatus is 'success'.
1133 --- 1.1.3 2010/04/21
1135 The SRU to Z39.50 filter does repeated Z39.50 present requests
1136 to fetch all records. Needed when a Z39.50 server returns partial
1137 results (due to message size limits).
1139 --- 1.1.2 2010/03/18
1141 Metaproxy now kills all child processes that are spawned by
1142 modules (in case of fork, exec).
1144 --- 1.1.1 2010/01/28
1146 Debian package now installs /etc/metaproxy/metaproxy.xml which
1147 includes all XML files /etc/metaproxy/filters-enabled .
1148 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1150 --- 1.1.0 2010/01/20
1152 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1153 development package to facilitate 3rd party Metaproxy modules.
1155 --- 1.0.23 2010/01/04
1157 Filter virt_db: Close backend filter session when Init rejected is received
1158 from it (in which case it's not really closed yet). This will ensure we don't
1159 run out of resources such as FDs in this case.
1161 sru_z3950 filter: Accept any database (including those not listed).
1163 --- 1.0.22 2009/12/03
1165 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1166 later which means YAZ 3.0.47 or later.
1168 --- 1.0.20 2009/11/19
1170 For filter virt_db, the database is a glob pattern and the virtual
1171 database sections are consulted in the order given.
1173 --- 1.0.19 2009/07/08
1175 For filter multi, the target (for routing) may be given as a glob-pattern.
1177 More documentation for filters virt_db and multi.
1179 Update schema to allow for no database in sru_z3950 filter.
1181 --- 1.0.18 2009/06/30
1183 Added limit filter to put sleep (penalty) for heavy use.
1185 Filter frontend_net may be configured to limit the number of new connections
1186 from same IP to some value (connect-max).
1188 Fixed the load_balance filter.
1190 --- 1.0.17 2009/06/16
1192 Fix path for metaproxy executable for Debian init.d script.
1194 --- 1.0.16 2009/06/10
1196 SRU to Z39.50 filter honors x-username and x-password. If only
1197 x-username is given that translates to open authentication (Z39.50v2). If
1198 both x-username and x-password is present that translates to idPass
1199 authentication (Z39.50v3).
1201 New facility to change current working directory (-w).
1203 Update to upstream skeleton of init.d script. Should fix bug #2619.
1205 Filter session_shared now caches records (used to only cache connections
1208 Filter session_shared now invalidates a Z39.50 session if a server
1209 returns -1 hits. This facility was also part of yazproxy and gets around
1210 a bug in Voyager-based Z39.50 servers.
1212 --- 1.0.15 2008/11/18
1214 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1216 --- 1.0.14 2008/06/09
1218 Fixed the value of SRU record schema in searchRetrieve response. It was set
1219 to a fixed value of "dc" before.
1221 Serialize identical SRU requests. This is useful if HTTP client software
1222 fires identical requests against metaproxy.
1224 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1225 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1226 avoid static configuration. This facility is handled by the sru_z3950 module
1227 and the z3950_client module.
1229 Allow maximum number of sockets to be used for a Z39.50 client by the
1230 use of SRU extra parameter x-max-sockets. This facility is handled by the
1231 sru_z3950 module and the z3950_client module.
1233 --- 1.0.13.1 2008/02/29
1235 Simplified check for Boost libraries.
1237 --- 1.0.13 2008/02/29
1239 First Debian package.
1241 The sru_z9350 filter now recognizes SRU parameter z-target as being
1242 a ZURL of the form host/database .
1244 Mergetype may be specified for filter 'multi'.
1246 --- 1.0.12 2007/09/19
1248 Fixed problem in Makefile WRT library specifictions. This could produce
1249 linker errors (when they should not happen).
1251 Fixed bug #1341: MetaProxy returning different results. Problem was that
1252 fix-up of record database did not normalize the database name.
1254 Documentation updates for Windows compilation.
1256 --- 1.0.11 2007/06/14
1258 Fixed problem with logfile being truncated.
1260 --- 1.0.10 2007/05/23
1262 Fixed bug #1136: Access rights not enforced.
1264 Extension for log module. The log category 'access' logs more details.
1265 New category 'user-access' added which is simlar to 'access' but adds
1266 the Z39.50 user as for all entries in a session.
1270 Added support for configurable default/force target/vhost for module Z39.50
1273 --- 1.0.8 2007/01/25
1275 Implemented filter, session_shared, which optimizes usage of Z39.50
1276 sessions and result sets.
1278 New filter, record_transform, which converts MARC/XML records.
1280 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1282 New filter, load_balance, in development.
1284 New filter, zeerex_xplain.
1286 XML framework for config files started.
1288 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1289 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1290 XML config files are checked against RNG and XML Schema's.
1292 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1293 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1294 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1295 explain record to YAZ CQL-to-PQF text config file.
1297 --- 1.0.7 2006/11/07
1299 Added 'timeout' setting for filter frontend_net which specifies the number
1300 of seconds a session is idle before it is closed. Default timeout is
1303 --- 1.0.6 2006/07/07
1305 Database name in records returned set for virt_db/multi filters.
1307 Filter session_shared now functional.
1309 Log filter can be configured to write to a given file using 'filename'
1310 element. Also information category can be specified with 'category'. If
1311 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1314 --- 1.0.5 2006/05/16
1316 Fixed compilation on Windows.
1318 --- 1.0.4 2006/05/16
1320 Added documentation for the hidenavailable option for the multi filter.
1322 --- 1.0.3 2006/05/16
1324 Fixed bug #573: Hide errors for individual servers. If the element
1325 'hideunavailable' is given in the configuration, individual servers
1326 being unavailable are hidden (unless all are unavailable).
1328 Fixed bug #574: Database names are recognised case-sensitively.
1330 Fixed bug #567: Fix up database name in Name-Plus-Record.
1332 Fixed bug #568: Update win/makefile for VS 2005.
1334 Fixed bug #569: Some options throws unknown exception.
1336 --- 1.0.2 2006/04/28
1338 More information about virtual hosts. The 'etc' directory is part of the
1341 --- 1.0.1 2006/04/27
1343 Build instructions for Windows. NMake makefile part of distribution tar.
1345 --- 1.0.0 2006/04/24
1349 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1350 log, multi, query_rewrite, template, virt_db, z3950_client.
1352 Filters in development: session_shared.
1354 Pseudo-filters: template, dl
