3 Log rotate no longer reloads configuration - instead Metaproxy just
4 re-opens log files when SIGHUP is received. MP-485
6 Debian : init.d metaproxy reload should check configuration MP-591
8 Fix Metaproxy stops logging after check config failed MP-590
12 Fix double free in log filter (with incorrect config) MP-589
14 zoom: Add allow_ip feature - fixes MP-588
15 Allow a list of IPs to be given separated by blanks
16 <allow auth_url="http://mkc-admin.indexdata.com/..."
17 allow_ip="127.0.0.1 ::1" .. >
19 cql2pqf.txt: Maps dc.subject to Bib-1 21 rather than 47
21 zoom: fix CS write-check
25 zoom: handle contentAuthentication MP-587
29 Destroy router and filters in parent process MP-584
31 Update NMAKE makefile to use Visual Studio 2013 along with Boost 1.57,
32 ICU 54.1, Libxml2 2.9.2, Libxslt 1.1.28.
36 Use YAZ backtrace facility MP-582
38 Fix libmetaproxy-dev depends on libgnutls-dev - MP-580
39 libgnutls-dev is unavailable on jessie.
41 Update template filter to avoid Pimpl MP-579
43 cgi: POSTed content - part of MP-562
45 Fix filter cgi does not relay session close MP-577
49 Add support for binding outgoing IP for http_client and z3950_client
50 This is enabled by bind_host setting. MP-575
54 z3950_client: allows negotiation charset to be set MP-574
56 cgi: more functional but no support for POSTed content yet (part of MP-564)
60 http_file: add include of sys/stat.h fixes MP-576
62 Fix documentation about SRU client support MP-572
64 Initialize Libxml2 - for threaded operation MP-571
68 On SIGTERM shut down connection+listening sockets MP-568
69 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
73 zoom: make retry on failure configurable MP-565
74 The default and existing behavior is that backend failures (any
75 diagnostic) makes the module re-search once. The behavior may
76 be changed by db parameter 'retry'. If given value '0' disables
77 retry and '1' enables it. If not given, the Torus record may
78 specify with element retryOnFailure (value '0'/'1').
82 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
83 instead of just a child process. Extremely rare in real life, hit me with
84 CF stress testing. MP-559.
88 http_file: passthru option MP-557
89 New facility for http_file to passthru - even if an area is matched. The
90 default behavior (passthru=false) is to return 404: Not found. With
91 passthru=false, next filter is consulted.
95 Fix ref to freed memory in log filter 1line - MP-556
97 echoedSearchRetrieveRequest support MP-555
101 zoom: allow hostname to be given for ipauth MP-552
102 The Torus setting for that is called auth_hostname.
106 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
110 session_shared: close in ~BackendInstance MP-549
111 This fixes a serious issue where some MP would leak sockets.
113 session_shared: mutex lock in BackendClass::release_backend MP-550
114 Fixes a SEGV that could occur (in rare cases).
118 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
120 zoom: fix invalid present response in some cases MP-546
122 zoom: Relay Torus HTTP error message
126 Check for proper limits before using RecordCache functions MP-544
130 Build packages for Ubuntu Trusty Tahr 14.04 LTS

140 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
144 sru_z3950: fix facet response (memory corruption) MP-532
146 log: fix crash idPass user is omitted MP-530
150 query_rewrite: pass-thru non Type-1 queries MP-527
152 metaproxy stop (SIGTERM) kills all child processes spanwed by
153 filter (if any) before invoking filter destructors. MP-525
157 http_file: only supports HTTP GET MP-523
159 session_shared: shut down expire thread in destructor
160 This ensures that expire thread is not running after destruction
161 and does bad memory references, etc.
163 frontend_net: fix segfault on startup MP-524
164 Would happen if MP was listening on multiple ports and one
165 of the ports was already in use (and MP would exit).
167 frontend_net: fix memory leak MP-521
168 This leak would occur if all sessions were in use and the input
169 queue was cleared when a client would close connection (socket).
171 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
175 http_rewrite: use local skiplist; fixes memory corruption. MP-520
177 http_client: x-forwarded-for controls X-Forwarded-For presence
178 If x-forwarded-for setting (boolean) is enabled, http_client will
179 generate an X-Forwarded-For header entry which includes existing
180 X-Forwarded-For (if any) and current peer address (immediate client
181 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
182 will not be generated.
184 z3950_client: client_ip controls client-IP presence
185 If client_ip setting (boolean) is enabled, z3950_client will
186 generate a client_ip OID as part of init request which includes
187 previous client_ip (if any) and current peer address (immediate
188 client of Metaproxy). By default client_ip is disabled and client_ip
189 will not be generated.
191 HTTP X-Forwarded-For/Z39.50 Client-IP support
192 virt_db, multi: relays Z39.50 client-IP.
193 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
194 zoom: uses Client-IP or origin address (prefer Client-IP).
195 frontend_net: Strips tcp: from peer address (so that it is no longer
196 printed and stripped in zoom filter).
197 z3950_client: builds client-IP list - combining immediate peer address
198 as returned by COMSTACK and existing client-IP list (if avaiable).
199 The Origin only printes first X-Forwarded address.
203 Log when SIG{TERM,USR1} is received ASAP MP-513
204 Do it in frontend_net event loop rather than in place for metaproxy
205 main, which only exits when all sessions are terminated for SIGUSR1
208 metaproxy-config: quote some RHS values (that might include blanks)
210 Fix leak in sru_z3950 filter - when explain is returned MP-511
212 Allow stylesheet to be given for sru_z3950 filter MP-510
213 This is based on a patch by Sven Porst and the functionality
214 of the YAZ Generic Frontend Server.
216 Allow base attribute in configuration file tags - the attributes are
217 inserted by XInclude usage as mentioned on
218 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
219 and noted in a gist: https://gist.github.com/3551094
221 Package metaproxy provides virtual package metaproxy6 MP-508
222 This allows module packages to depend on a metaproxy server
225 Filter destructors called upon daemon termination MP-505
226 When metaproxy daemon receives SIGTERM the stop method of each filter
227 is called. The stop method existed before, but did not take any
228 arguements (void).. The frontend_net filter can now distinguish
229 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
230 (stop immediately). Note that this changes the API+ABI of Metaproxy
233 zoom: sync up with Pazpar2 WRT authentication handling MP-492
235 Router: use shared_ptr rather than naked one - to avoid leak if an
236 exception is thrown in configure.
240 zoom: Add nocproxy=1 for contentConnector sessions MP-501
242 Doc: mention proper versions; fix link to Boost win binaries.
244 Windows: update for Boost 1.55
246 Windows: avoid warning when using boost::split. Done by defining
247 _SCL_SECURE_NO_WARNINGS for Visual Studio.
249 Fix LSB conformance for /etc/init.d/metaproxy MP-500
250 Debian: add support for /etc/init.d/metaproxy status
252 sort: Add const to Record less than operator in order to compile on
257 session_shared: fix element-set handling in record caching. MP-499
259 document http_rewrite. MP-468
261 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
262 respects the header (which will normally come from the cproxy filter)
266 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
267 RPM was unsable in version 1.4.0.
269 Remove log message about "backend classes". Appeared in version 1.4.0.
273 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
274 with older version from source, but packages now use YAZ 5 that supports
277 sru_z3950: Fix SEGV for decoding invalid SRU requests
278 Incorrect reference to union (was explain response rather than
281 session_shared: match additionalSearchInfo (includes facets). In
282 layman's terms means that means that facets are properly handled
283 by this filter. Eg a change in requested facets will issue new
284 search and facets from exisiting result set are cached.
286 --- 1.3.62 2013/09/11
288 http_rewrite: better handling of <script> content in HTML parser. MP-486
290 http_rewrite: fix threading issue with regex. MP-482
292 bounce: don't use strdup for fixed length content. Error occurred in echo
295 session_shared: expire backend class when no instances left. This
296 means memory clean up, but not really a leak fix.
298 virt_db: fix leak for naked ptr.
300 cql_rpn: use config relative path for cql2rpn file. MP-481
302 Updates for upcoming YAZ 5.
304 --- 1.3.61 2013/08/29
306 New configuration directories ports.d/routes.d for metaproxy
307 configuration. This allows 3rd party packages to install config
308 for ports and new routes. MP-477
310 --- 1.3.60 2013/08/21
312 Fix metaproxy-config --libs to return non-mt over mt libs.
313 The -mt versions do not exist as shared objects and cause
314 linker errors for applications linking with Metaproxy.
315 Problem present in versions 1.3.56 - 1.3.59. MP-475
317 HTML: clean up char checks. Add ptr to HTML parse spec
319 HTML parser stops eating tag when <-char is met MP-473
321 rewrite: do not even compare content types, if we don't have any
322 the regex_match caused a segfault if we had no content-type in the
325 rewrite: within header=... matches only the header value
326 Used to match the whole header line, but we need to use
327 ^$ anchoring for host-relative regexps, and they need to
328 anchor at the ends of the value. MP-470.
330 rewrite: Ruleset functional MP-469
332 --- 1.3.59 2013/07/12
334 session_shared: negotiate init sz parameters.
335 By default, session_shared will honor the paramters given by client.
336 An alternative, but not implemented, algorithm would be to only
337 re-use sessions with same sz parameters. This however, could reduce
338 re-use of sessions a lot. Hence this, simple algorithm instead. The
339 negotiation to a maximum sz values can be enabled by using
340 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
341 in configuration. This will make session_shared send those values
342 to backends and use returned init values in negotaition to
343 client before session_shared.
345 session_shared: resolve result-set references.
346 The reference is substitued with the query for old set if database
347 match and query type is Type-1. If not the reference will issue a
350 sort filter: relays RecordComposition including elementSet in use for
353 http_client: better diagnostics
355 http_client: disables HTTP redirect handling by default.
356 It can be configured with max-redirects in configuration.
358 --- 1.3.58 2013/06/12
360 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
362 --- 1.3.57 2013/06/12
364 Make RouterChain and RouterXML part of public API (libmetaproxy).
366 http_client: honor X-Metaproxy-Proxy as an alternative to
367 the "proxy" configuration. Allows proxy to be set per HTTP request.
369 sru_z3950: For SRU requests recognize x-client prefixes as a way
370 to ingest "database parameters".. The suffix of x-client- serves
371 as database argument name. Multiple may be given. For example:
372 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
373 is turned into Z39.50 database
376 --- 1.3.56 2013/05/27
378 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
380 New filter sd_remove, which replaces surrogate diagnostics with
381 SUTRS records. This filter tries to deal with clients that breaks
382 when receiving surrogate diagnostics.
384 new filter http_client. Same role as z3950_client, but just for
385 HTTP. Allows Metaproxy to operate as a HTTP proxy.
387 New filter http_rewrite1, which serves as purpose on how to rewrite
388 HTTP content with Metaproxy.
390 Use libboost-system if available, because newer versions of libboost-threads
391 requires libboost-system.
393 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
396 --- 1.3.55 2013/04/10
398 zoom: Torus setting: authenticationMode which may hold values "basic"
401 --- 1.3.54 2013/03/27
403 configure: check for Libxslt support in YAZ and rely on definitions
404 from yaz-config, rather than doing own xslt/xml2 checks.
406 Allow timestamp format for log lines to be given with option -m
407 for metaproxy. Similar to yaz-ztest/GFS option -m.
409 Document log category 'line' for log filter.
411 Solr configuration example in etc/config-solr.xml
413 multi: do not mess with request package. For scan and search,
414 database-names were modified and the request package was left with
415 dangling pointers that caused a log filter to fail (request package
416 inspected after multi was invoked).
418 Documentation: fix id of metaproxy-config ref .
420 Documentation: update for USEMARCON support.
422 --- 1.3.53 2013/01/31
424 record_transform: allow OPACXML to OPAC conversion
426 zoom: document content-proxy
428 zoom: document db parm content-{user,password}, torus_url. Also
429 <torus auth_url="..> which makes zoom operate in authenticated mode
432 --- 1.3.52 2012/11/30
434 zoom: fix http://-check. SRU search broken in 1.3.51.
436 --- 1.3.51 2012/11/15
438 zoom: only append http:// for SRU if not already given . Makes it
439 possible to use https-URLs.
441 Use yazpp 1.4 or later due to new ABI.
443 frontend_net: allow max package size to be specified. Controlled by
444 attribute 'max_recv_bytes' of element 'port'.
446 --- 1.3.50 2012/10/29
448 For most generated diagnostics by filters, typically temporary
449 system error, augment addinfo message with filter name.
451 Add support for CentOS 6 packages.
453 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
455 Add man page for metaproxy-config.
457 --- 1.3.49 2012/10/18
459 zoom: new config element passthru. This defines an element set that is
460 passed verbatim to the backend in pz2 mode.
462 auth_simple: allow both idPass and open auth. Also fix SEGV that could
465 --- 1.3.48 2012/10/08
467 z3950_client: fix string handling for init diagnostics in the case where
470 query_rewrite: no charset conversion for error queries. Avoid performing
471 charset conversion for query conversion errors. The resulting Type-1
472 query is invalid in this case.
474 --- 1.3.47 2012/10/04
476 For graceful stop (SIGUSR1), metaproxy will kill children processes.
478 Log when metaproxy is invoked in test mode (-t).
480 Log PID for each log message.
482 multi: combine both NSDs and multiple NSDs into one (diagnostics).
484 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
485 a (backend=target) is appended for each diagnostic so that can be
486 determined the origin of error.
488 multi: hideerrors also in use for present response.
490 Solr example in zoom man page.
492 Fix typo in query_rewrite config example.
494 Log at least first non surrogate diagnostic. Instead of
495 "Z_Records_multipleNSD"
497 multi: Fix check for opt Records in present response. A SEGV could occur
498 if a target did not return records and no diagnostics.
500 --- 1.3.46 2012/09/24
502 Yet another fix for graceful stop.
504 --- 1.3.45 2012/09/12
506 sru_z3950: relay surrogate diagnostics.
508 --- 1.3.44 2012/09/10
510 zoom: Honor extraArgs, strip # in zurl.
512 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
514 zoom: url_recipe allow %{var[reg]} substitutions.
515 It's like ${var[reg]} but does URI component encoding as well.
517 --- 1.3.43 2012/08/22
519 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
520 non-keepalive HTTP sessions.
522 http_file: allow zero size files (bug fix)
524 Fix zoom schema: auth_url is optional
526 --- 1.3.42 2012/08/20
528 zoom: fix un-init memory (could result in SEGV at session close)
530 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
531 and may be used in filters as usual.
533 zoom: authentication via Torus lookup
534 Enabled by new configuration setting: auth_url . If this is defined,
535 the zoom module will contact Torus for auth/IP lookup and that will
536 define realm to be used in session.
538 --- 1.3.41 2012/08/10
540 virt_db: Fix database name - first character we removed by mistake.
541 Bug introduced in 1.3.40.
543 --- 1.3.40 2012/08/06
545 virt_db: Don't use "unix path" as database for Unix sockets.
547 --- 1.3.39 2012/08/02
549 z3950_client: Don't tamper with / in zurl - fixes problems
550 using Unix sockets for backends.
552 session_shared: fix integer overflow problem with hit count.
554 session_shared: avoid long usage of cached queries.
556 zoom: New database argument , torus_url to set URL of Torus
557 record to be fetched.
559 --- 1.3.38 2012/07/04
561 Fixes for 'metaproxy reload' for RPM/Debian packages.
563 zoom: Allow rpn2cql conversion to be augmented with a properties file.
564 Element rpn2cql can be specified per-target for the zoom filter.
566 log: New category "line" which is a single-line log message with
567 most important parts of a HTTP/Z39.50 request/response.
569 --- 1.3.37 2012/06/01
571 frontend_net: add facility to report live statistics about response
572 times and current thread usage. The report is an XML document
573 and is triggered for a specific URL path. This is set by <stat-req>
574 in the configuration of frontend_net. By default this report is
575 disabled (same as empty value for <stat-req>).
577 Fix reload problem in init.d script for RPM/Debian.
578 The '/etc/init.d/metaproxy reload' in some cases would stop but not
579 start metaproxy - effectively stopping the service.
581 Don't display start log message when config testing (-t).
583 zoom: avoid CCL message limit of 1K in ZOOM filter.
585 --- 1.3.36 2012/05/10
587 metaproxy init script reacts to reload which does graceful stop +
588 start and is used by logrorate script.
590 --- 1.3.35 2012/05/09
592 Fixes for Windows compilation.
594 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
595 existing sessions running but terminate the monitor process that is
596 used in keepalive mode.
598 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
599 before. Consistent with 'metaproxy stop' message.
601 zoom: document zoom's proxy_timeout
603 z3950_client: fixup addinfo for init response
605 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
606 "Access to specified database denied" is returned, but only if init
607 response from backend does not carry diagnostics already.
609 multi: relays user info for first rejected target. The other-information
610 field for init response for first rejected target is in common init
611 response. This ensures that some backend init diagnostics are returned to
614 --- 1.3.34 2012/04/25
616 frontend_log: extend logging (when message is given in config).
618 --- 1.3.33 2012/04/25
620 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
622 --- 1.3.32 2012/04/24
624 sru_z3950 filter passes through incoming Z39.50 requests again. Was
625 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
627 --- 1.3.31 2012/04/24
629 zoom: fixes for retry/proxy failover logic. More logging.
631 --- 1.3.30 2012/04/23
633 zoom: return addinfo="proxy failure" for proxy failures. This also
634 changes the scheme for dealing with proxies a bit. zoom now always
635 do proxy check, even if there's no failover. Fortunately, that's not
638 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
639 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
640 generic. We don't know why the init would fail; IP, user, block IP, etc.
641 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
643 zoom: guess if invalid SRU response was an auth failure
645 session_shared: disable session retry by default . Can be enabled by
646 restart="true" in resultset section.
648 --- 1.3.29 2012/04/18
650 zoom: may read cf-proxy's config settings.
651 This reduces manual configuration of the content proxy server host.
652 The ZOOM module will use the old style session.proxyhost if "server"
653 is given (deprecated) and use the new style proxyhost/session if
654 "config_file" is in use.
656 frontend_net: remove incoming requests that can not be handled
657 Requests in queue for filter frontend_net are removed if client
658 closes connection for the session and request is not yet handled.
660 sru_z3950: serialize requests. This is to ensure that pipelined
661 HTTP requests are handled properly.
663 --- 1.3.28 2012/04/04
665 New class, wrbuf, that wraps YAZ' WRBUF.
667 --- 1.3.27 2012/03/30
669 Metaproxy daemon is now running as user "metaproxy". This user is
670 managed by package maintainer scripts. The user information is stored
671 in /etc/metaproxy/metaproxy.user .
673 --- 1.3.26 2012/03/20
675 New filter, sort, that allows sorting of XML records via Z39.50
678 Filter record_transform: USEMarcon support. For example:
679 <retrieval syntax="usmarc">
680 <backend syntax="unimarc" name="F">
681 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
685 Filter multi: empty route pattern uses route as default.
687 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
688 may use the shorter notation
689 <target route="z3950.indexdata.com"/>
691 Filter query_rewrite: use config path to locate XSLT.
693 Filter frontend_net: log statistics.
694 If a custom message element in frontend_net configuration it makes
695 the frontend_net filter produce a log entry whenever an operation
696 is completed. The log is always written using yaz_log with the
697 custom message given, the package ID (session ID) , the time
698 the operation has been active (end-to-end) , the threads currently
699 active/total and the size of the request input/output queues.
701 query_rewrite: charset conversion of query terms.
702 This is an optional feature. Enabled by element <charset> in
703 configuration with attribute 'from' and 'to' that specifies
704 from/to encodings. The default 'from' encoding is UTF-8.
706 Filter record_transform: honor piggyback searches.
708 Filter zoom: re-connect when database is reused.
709 Re-connect is necessary if a connection is lost or a timeout occurs.
710 If not, we'll be seeing zero hits, when we shouldn't.
712 --- 1.3.25 2012/02/29
714 zoom: Change scheme for dealing with content proxy URLs. The module
715 now has its own common XSL transform that is enabled by record_xsl
716 attribute in the configuration. This XSL gets parameter cproxyhost
717 that holds the host for the content proxy session . The genearted-url
718 is created only if urlRecipe is enabled. In previous version default
719 value of urlRecipe was ${md-electronic-url}; it is now empty and
720 disabled by default. Also generated-url no longer includes the content
721 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
724 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
725 connections. Default value is 40 (seconds).
727 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
728 "Malformed query" for syntax errors and related ones; throw
729 Bib-1: 3 "Unsupported search" for everything else. Details from
730 the CCL parser is provided as additional-info.
732 multi: new setting hideerrors that makes multi only relay diagnostics
733 to a client if all backends fail.
735 --- 1.3.24 2012/02/23
737 zoom: empty ccl_map field-mappings disables CCL map.
739 zoom: fix Explain search that could return error if session was
742 --- 1.3.23 2012/02/10
744 zoom: returns Explain records for database IR-Explain---1. The
745 target profile records are converted to Explain records via XSLT.
747 session_shared: make error recovery configurable. Whether a search
748 is restarted on errors or not, is configurable by attribute "restart"
749 in element "resultset" in configuration.
751 session_shared: only relay init for first request. session_shared, for
752 each backend class, now only relays first init request (rather than all).
753 The module only needs to save init response info once. This avoids the
754 need to check for session max.
756 --- 1.3.22 2012/02/02
758 zoom: fix memory leaks.
760 session_shared: maximum number of sessons is configurable. Default
761 value is 100. Result-sets for backends without named result sets are
762 only re-used if databases is identical for a search. This is under the
763 assumption that performance may suffer for those backends when
764 changing the database for each search.
766 multi: combines diagnostics from all backends. All diagnostics from
767 backends are combined into multiple non-surrogate diagnostics; rather
768 than just one diagnostic from first backend.
770 --- 1.3.21 2011/12/27
772 zoom: relay realm to cproxy parameter file.
774 Configuration: Allow filter collection element inside route. This
775 makes it possible to include multiple filters at once.
777 zoom: nocproxy also disables urlRecipe.
779 --- 1.3.20 2011/12/21
781 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
782 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
783 90: "Unsupported direction value".
785 zoom: honor database argument nocproxy. This disables creating a content
786 connector session (for non-CF targets, usually) and also relays nocproxy
787 as database argument to a CF target.
789 --- 1.3.19 2011/12/16
791 zoom: Multiple proxy hosts may be given for proxy rich database
792 parameter. List is comma separated.
794 http_file: decodes URI paths properly. Does not return 404: not found
795 if no prefix are matches. Instead packages are passed on.
797 --- 1.3.18 2011/12/08
799 zoom: content-{user,password,proxy} are passed on to content proxy
800 system and takes precedence over user,password,proxy .
802 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
803 with a log element including log material from children filters. At
804 this point, only the zoom filter uses this log facility. It will
805 eventually be used by other filters as well. In particular it might be
806 useful for this feature to track all filters in used during a search.
808 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
809 and queries as they are manipulated are logged.
811 zoom: extend addinfo with native diagnostics. Diagnostics as received
812 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
813 diagnostics. This indicates both a backend diagnostic and the original
816 zoom: default urlRecipe value is ${md-electronic-url}
818 zoom: target profile setting sruVersion is recognized.
820 --- 1.3.17 2011/11/17
822 zoom: log target profile record fetched (AKA Torus).
824 --- 1.3.16 2011/11/17
826 Change target profile parameter CfSubDb to CfSubDB.
828 --- 1.3.15 2011/11/12
830 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
831 makes sense to the zoom module itself).
833 --- 1.3.14 2011/11/11
835 zoom: realm may be given as part of database.
837 --- 1.3.13 2011/10/26
839 Fix Origin class assigment method; was removd by mistake in 1.3.12.
841 --- 1.3.12 2011/10/26
843 zoom: database args x-name=value are passed through to backend database.
845 SRU filter: user may specify session ID that is passed to log entries
846 that follows. It is specified by using x-session-id in the SRU arguments.
848 zoom: fix null pointer reference which would occur for bad url parameter
849 inside "torus" or if url was not given.
851 --- 1.3.11 2011/09/09
852 Fix bug in filter session_shared where sessions would not expire
853 properly (session ttl). This in turn could make the target close the
854 connection before expected and session_shared would return diagnostic
855 2: system temporarily available.
857 --- 1.3.10 2011/09/09
859 zoom: new target profile setting: sortmap_field. If sortmap_field is given
860 the field is mapped to the value for the sortmap. Values not matching
861 sortmap_field are passed verbatim.
863 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
864 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
865 depending on whether RPN or CQL is actually sent to the target.
869 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
871 zoom: For content proxy authentication is stored in param name
872 "auth", instead of "authentication".
876 zoom: relay schema in SRU mode. Previously recordSchema was not affected
881 zoom: new target profile element literalTransform that holds XSLT
882 (encoded as string) for target. Only if present and non-zero length it is
883 considered present. This takes precedence over transform.
885 Don't rely on trang anymore for Git checkout builds. Configuration in etc
886 will only be properly validated if trang is available. From now on only
887 relax NC files are bundled with the source dist.
889 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
890 component was not detected when it should be.
894 z3950_client: mark non-surrogate diagnostics from backend.
896 zoom: a proxy may be specified for HTTP fetch of target profiles.
900 Honor piggyback. Makes some SRU targets behave that insist on
901 maximumRecords > 0, but also increases performance.
905 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
906 file was not update for libdir/metaproxy4 in version 1.3.2.
910 Change location of Metaproxy modules from libdir/metaproxy to
911 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
912 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
914 New facility to dump APDUs from zoom filter. Enabled by
915 <log apdu="true"/> in the zoom filter configuation.
917 zoom filter bug fix: SRU diagnostics received from backend was
918 not properly converted to Bib-1 diagnostics.
920 Package metaproxy depends on libmetaproxy4, same version.
924 zoom: fix a bug WRT passing authentication parameters to backends.
928 Fixes for windows Makefile.
930 --- 1.2.10 2011/07/25
932 Change major version of metaproxy library from 3 to 4. This in turn
933 makes new package names for Debian and RPM.
937 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
940 zoom: configurable element sets for record transforms.
942 zoom: the target profile based transform is specified by element_transform
943 in element torus of of the ZOOM filter configuration ; default value
944 is "pz2". Target profile based retrieval is specified by element_raw
945 in configuration. It will perform same steps, but omit the XSL transform.
946 Default value is "raw".
948 zoom: element set is omitted if not set in profile. But only if pz2
949 transform is in effect. Previously the default element set was to "F".
951 zoom: For non-CF targets database arguments are parsed. User may supply
952 db,user=myuser&password=mypass for non-CF targets. These values override
953 what's given the authentication from the target profile.
955 session_shared: fix reference to freed memory. Would occur if a search
956 response had non-surrogate diagnostics.
960 Route may be given for each port in frontend_net.
964 Documentation for zoom filter. Local target profiles may be specified.
966 Fixes for zoom filter.
970 First version with zoom filter.
974 Filter z3950_client may be configured to always send a close APDU
975 to backend target when connection/session is closed. This will only
976 happen if close APDU is not already sent. Enabled by configuration
977 for z3950_client (force_close).
979 Filter virt_db and multi: relay close APDU.
981 Filter virt_db and multi: relay init size parameters
982 preferredMessageSize and maximumRecordSize.
984 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
988 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
990 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
991 as determined by configure.
993 RPM: Release includes 'indexdata' name. Use indexdata in release name so
994 this package can be distinguished from other vendors.
998 Fix filter multi: relay idAuthentication parameters.
1000 --- 1.2.2 2010/09/15
1002 Add metaproxy-config for returning compiler flags, libraries.
1004 --- 1.2.1 2010/08/18
1006 Fix --with-boost=PREFIX .
1008 --- 1.2.0 2010/07/09
1010 session_shared: fix use of maintenance thread.
1012 Introduce 'start' method for filters and routers. It gets called after
1013 configure and after fork, but before processing. This changes API -
1014 from libmetaproxy2 to libmetaproxy3.
1016 --- 1.1.7 2010/06/30
1018 session_shared: ensure backend session is closed if init rejected
1021 z3950_client: fix NULL ptr reference that could occur if two clients
1022 connected concurrently and if max-sockets was in effect.
1024 --- 1.1.6 2010/06/21
1026 Fix bug 3497 - Metaproxy unstable while stopping.
1028 Fix bug 3495 - SEGV in SRU filter.
1030 --- 1.1.5 2010/06/15
1032 Filter multi throws diagnostic 'Present Out of Range' when
1033 appropriate - rather than returning 0 records.
1035 Filter virt_db: fix bad result reuse. Could happen if a result
1036 was overriden and a backend did not supported named result sets.
1038 --- 1.1.4 2010/05/11
1040 Filter log: category access logs diagnostics even if searchStatus
1041 or presentStatus is 'success'.
1043 --- 1.1.3 2010/04/21
1045 The SRU to Z39.50 filter does repeated Z39.50 present requests
1046 to fetch all records. Needed when a Z39.50 server returns partial
1047 results (due to message size limits).
1049 --- 1.1.2 2010/03/18
1051 Metaproxy now kills all child processes that are spawned by
1052 modules (in case of fork, exec).
1054 --- 1.1.1 2010/01/28
1056 Debian package now installs /etc/metaproxy/metaproxy.xml which
1057 includes all XML files /etc/metaproxy/filters-enabled .
1058 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1060 --- 1.1.0 2010/01/20
1062 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1063 development package to facilitate 3rd party Metaproxy modules.
1065 --- 1.0.23 2010/01/04
1067 Filter virt_db: Close backend filter session when Init rejected is received
1068 from it (in which case it's not really closed yet). This will ensure we don't
1069 run out of resources such as FDs in this case.
1071 sru_z3950 filter: Accept any database (including those not listed).
1073 --- 1.0.22 2009/12/03
1075 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1076 later which means YAZ 3.0.47 or later.
1078 --- 1.0.20 2009/11/19
1080 For filter virt_db, the database is a glob pattern and the virtual
1081 database sections are consulted in the order given.
1083 --- 1.0.19 2009/07/08
1085 For filter multi, the target (for routing) may be given as a glob-pattern.
1087 More documentation for filters virt_db and multi.
1089 Update schema to allow for no database in sru_z3950 filter.
1091 --- 1.0.18 2009/06/30
1093 Added limit filter to put sleep (penalty) for heavy use.
1095 Filter frontend_net may be configured to limit the number of new connections
1096 from same IP to some value (connect-max).
1098 Fixed the load_balance filter.
1100 --- 1.0.17 2009/06/16
1102 Fix path for metaproxy executable for Debian init.d script.
1104 --- 1.0.16 2009/06/10
1106 SRU to Z39.50 filter honors x-username and x-password. If only
1107 x-username is given that translates to open authentication (Z39.50v2). If
1108 both x-username and x-password is present that translates to idPass
1109 authentication (Z39.50v3).
1111 New facility to change current working directory (-w).
1113 Update to upstream skeleton of init.d script. Should fix bug #2619.
1115 Filter session_shared now caches records (used to only cache connections
1118 Filter session_shared now invalidates a Z39.50 session if a server
1119 returns -1 hits. This facility was also part of yazproxy and gets around
1120 a bug in Voyager-based Z39.50 servers.
1122 --- 1.0.15 2008/11/18
1124 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1126 --- 1.0.14 2008/06/09
1128 Fixed the value of SRU record schema in searchRetrieve response. It was set
1129 to a fixed value of "dc" before.
1131 Serialize identical SRU requests. This is useful if HTTP client software
1132 fires identical requests against metaproxy.
1134 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1135 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1136 avoid static configuration. This facility is handled by the sru_z3950 module
1137 and the z3950_client module.
1139 Allow maximum number of sockets to be used for a Z39.50 client by the
1140 use of SRU extra parameter x-max-sockets. This facility is handled by the
1141 sru_z3950 module and the z3950_client module.
1143 --- 1.0.13.1 2008/02/29
1145 Simplified check for Boost libraries.
1147 --- 1.0.13 2008/02/29
1149 First Debian package.
1151 The sru_z9350 filter now recognizes SRU parameter z-target as being
1152 a ZURL of the form host/database .
1154 Mergetype may be specified for filter 'multi'.
1156 --- 1.0.12 2007/09/19
1158 Fixed problem in Makefile WRT library specifictions. This could produce
1159 linker errors (when they should not happen).
1161 Fixed bug #1341: MetaProxy returning different results. Problem was that
1162 fix-up of record database did not normalize the database name.
1164 Documentation updates for Windows compilation.
1166 --- 1.0.11 2007/06/14
1168 Fixed problem with logfile being truncated.
1170 --- 1.0.10 2007/05/23
1172 Fixed bug #1136: Access rights not enforced.
1174 Extension for log module. The log category 'access' logs more details.
1175 New category 'user-access' added which is simlar to 'access' but adds
1176 the Z39.50 user as for all entries in a session.
1180 Added support for configurable default/force target/vhost for module Z39.50
1183 --- 1.0.8 2007/01/25
1185 Implemented filter, session_shared, which optimizes usage of Z39.50
1186 sessions and result sets.
1188 New filter, record_transform, which converts MARC/XML records.
1190 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1192 New filter, load_balance, in development.
1194 New filter, zeerex_xplain.
1196 XML framework for config files started.
1198 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1199 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1200 XML config files are checked against RNG and XML Schema's.
1202 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1203 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1204 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1205 explain record to YAZ CQL-to-PQF text config file.
1207 --- 1.0.7 2006/11/07
1209 Added 'timeout' setting for filter frontend_net which specifies the number
1210 of seconds a session is idle before it is closed. Default timeout is
1213 --- 1.0.6 2006/07/07
1215 Database name in records returned set for virt_db/multi filters.
1217 Filter session_shared now functional.
1219 Log filter can be configured to write to a given file using 'filename'
1220 element. Also information category can be specified with 'category'. If
1221 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1224 --- 1.0.5 2006/05/16
1226 Fixed compilation on Windows.
1228 --- 1.0.4 2006/05/16
1230 Added documentation for the hidenavailable option for the multi filter.
1232 --- 1.0.3 2006/05/16
1234 Fixed bug #573: Hide errors for individual servers. If the element
1235 'hideunavailable' is given in the configuration, individual servers
1236 being unavailable are hidden (unless all are unavailable).
1238 Fixed bug #574: Database names are recognised case-sensitively.
1240 Fixed bug #567: Fix up database name in Name-Plus-Record.
1242 Fixed bug #568: Update win/makefile for VS 2005.
1244 Fixed bug #569: Some options throws unknown exception.
1246 --- 1.0.2 2006/04/28
1248 More information about virtual hosts. The 'etc' directory is part of the
1251 --- 1.0.1 2006/04/27
1253 Build instructions for Windows. NMake makefile part of distribution tar.
1255 --- 1.0.0 2006/04/24
1259 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1260 log, multi, query_rewrite, template, virt_db, z3950_client.
1262 Filters in development: session_shared.
1264 Pseudo-filters: template, dl
