3 z3950_client: allows negotiation charset to be set MP-564
5 cgi: more functional but no support for POSTed content yet
9 http_file: add include of sys/stat.h fixes MP-576
11 Fix documentation about SRU client support MP-572
13 Initialize Libxml2 - for threaded operation MP-571
17 On SIGTERM shut down connection+listening sockets MP-568
18 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
22 zoom: make retry on failure configurable MP-565
23 The default and existing behavior is that backend failures (any
24 diagnostic) makes the module re-search once. The behavior may
25 be changed by db parameter 'retry'. If given value '0' disables
26 retry and '1' enables it. If not given, the Torus record may
27 specify with element retryOnFailure (value '0'/'1').
31 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
32 instead of just a child process. Extremely rare in real life, hit me with
33 CF stress testing. MP-559.
37 http_file: passthru option MP-557
38 New facility for http_file to passthru - even if an area is matched. The
39 default behavior (passthru=false) is to return 404: Not found. With
40 passthru=false, next filter is consulted.
44 Fix ref to freed memory in log filter 1line - MP-556
46 echoedSearchRetrieveRequest support MP-555
50 zoom: allow hostname to be given for ipauth MP-552
51 The Torus setting for that is called auth_hostname.
55 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
59 session_shared: close in ~BackendInstance MP-549
60 This fixes a serious issue where some MP would leak sockets.
62 session_shared: mutex lock in BackendClass::release_backend MP-550
63 Fixes a SEGV that could occur (in rare cases).
67 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
69 zoom: fix invalid present response in some cases MP-546
71 zoom: Relay Torus HTTP error message
75 Check for proper limits before using RecordCache functions MP-544
79 Build packages for Ubuntu Trusty Tahr 14.04 LTS
81 sort: crash / invalid_read in filter sort MP-541
83 sru_z3950: facet should be stored in additionalSearchInfo MP-533
85 doc: fix missing man pages MP-542
87 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
89 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
93 sru_z3950: fix facet response (memory corruption) MP-532
95 log: fix crash idPass user is omitted MP-530
99 query_rewrite: pass-thru non Type-1 queries MP-527
101 metaproxy stop (SIGTERM) kills all child processes spanwed by
102 filter (if any) before invoking filter destructors. MP-525
106 http_file: only supports HTTP GET MP-523
108 session_shared: shut down expire thread in destructor
109 This ensures that expire thread is not running after destruction
110 and does bad memory references, etc.
112 frontend_net: fix segfault on startup MP-524
113 Would happen if MP was listening on multiple ports and one
114 of the ports was already in use (and MP would exit).
116 frontend_net: fix memory leak MP-521
117 This leak would occur if all sessions were in use and the input
118 queue was cleared when a client would close connection (socket).
120 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
124 http_rewrite: use local skiplist; fixes memory corruption. MP-520
126 http_client: x-forwarded-for controls X-Forwarded-For presence
127 If x-forwarded-for setting (boolean) is enabled, http_client will
128 generate an X-Forwarded-For header entry which includes existing
129 X-Forwarded-For (if any) and current peer address (immediate client
130 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
131 will not be generated.
133 z3950_client: client_ip controls client-IP presence
134 If client_ip setting (boolean) is enabled, z3950_client will
135 generate a client_ip OID as part of init request which includes
136 previous client_ip (if any) and current peer address (immediate
137 client of Metaproxy). By default client_ip is disabled and client_ip
138 will not be generated.
140 HTTP X-Forwarded-For/Z39.50 Client-IP support
141 virt_db, multi: relays Z39.50 client-IP.
142 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
143 zoom: uses Client-IP or origin address (prefer Client-IP).
144 frontend_net: Strips tcp: from peer address (so that it is no longer
145 printed and stripped in zoom filter).
146 z3950_client: builds client-IP list - combining immediate peer address
147 as returned by COMSTACK and existing client-IP list (if avaiable).
148 The Origin only printes first X-Forwarded address.
152 Log when SIG{TERM,USR1} is received ASAP MP-513
153 Do it in frontend_net event loop rather than in place for metaproxy
154 main, which only exits when all sessions are terminated for SIGUSR1
157 metaproxy-config: quote some RHS values (that might include blanks)
159 Fix leak in sru_z3950 filter - when explain is returned MP-511
161 Allow stylesheet to be given for sru_z3950 filter MP-510
162 This is based on a patch by Sven Porst and the functionality
163 of the YAZ Generic Frontend Server.
165 Allow base attribute in configuration file tags - the attributes are
166 inserted by XInclude usage as mentioned on
167 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
168 and noted in a gist: https://gist.github.com/3551094
170 Package metaproxy provides virtual package metaproxy6 MP-508
171 This allows module packages to depend on a metaproxy server
174 Filter destructors called upon daemon termination MP-505
175 When metaproxy daemon receives SIGTERM the stop method of each filter
176 is called. The stop method existed before, but did not take any
177 arguements (void).. The frontend_net filter can now distinguish
178 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
179 (stop immediately). Note that this changes the API+ABI of Metaproxy
182 zoom: sync up with Pazpar2 WRT authentication handling MP-492
184 Router: use shared_ptr rather than naked one - to avoid leak if an
185 exception is thrown in configure.
189 zoom: Add nocproxy=1 for contentConnector sessions MP-501
191 Doc: mention proper versions; fix link to Boost win binaries.
193 Windows: update for Boost 1.55
195 Windows: avoid warning when using boost::split. Done by defining
196 _SCL_SECURE_NO_WARNINGS for Visual Studio.
198 Fix LSB conformance for /etc/init.d/metaproxy MP-500
199 Debian: add support for /etc/init.d/metaproxy status
201 sort: Add const to Record less than operator in order to compile on
206 session_shared: fix element-set handling in record caching. MP-499
208 document http_rewrite. MP-468
210 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
211 respects the header (which will normally come from the cproxy filter)
215 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
216 RPM was unsable in version 1.4.0.
218 Remove log message about "backend classes". Appeared in version 1.4.0.
222 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
223 with older version from source, but packages now use YAZ 5 that supports
226 sru_z3950: Fix SEGV for decoding invalid SRU requests
227 Incorrect reference to union (was explain response rather than
230 session_shared: match additionalSearchInfo (includes facets). In
231 layman's terms means that means that facets are properly handled
232 by this filter. Eg a change in requested facets will issue new
233 search and facets from exisiting result set are cached.
235 --- 1.3.62 2013/09/11
237 http_rewrite: better handling of <script> content in HTML parser. MP-486
239 http_rewrite: fix threading issue with regex. MP-482
241 bounce: don't use strdup for fixed length content. Error occurred in echo
244 session_shared: expire backend class when no instances left. This
245 means memory clean up, but not really a leak fix.
247 virt_db: fix leak for naked ptr.
249 cql_rpn: use config relative path for cql2rpn file. MP-481
251 Updates for upcoming YAZ 5.
253 --- 1.3.61 2013/08/29
255 New configuration directories ports.d/routes.d for metaproxy
256 configuration. This allows 3rd party packages to install config
257 for ports and new routes. MP-477
259 --- 1.3.60 2013/08/21
261 Fix metaproxy-config --libs to return non-mt over mt libs.
262 The -mt versions do not exist as shared objects and cause
263 linker errors for applications linking with Metaproxy.
264 Problem present in versions 1.3.56 - 1.3.59. MP-475
266 HTML: clean up char checks. Add ptr to HTML parse spec
268 HTML parser stops eating tag when <-char is met MP-473
270 rewrite: do not even compare content types, if we don't have any
271 the regex_match caused a segfault if we had no content-type in the
274 rewrite: within header=... matches only the header value
275 Used to match the whole header line, but we need to use
276 ^$ anchoring for host-relative regexps, and they need to
277 anchor at the ends of the value. MP-470.
279 rewrite: Ruleset functional MP-469
281 --- 1.3.59 2013/07/12
283 session_shared: negotiate init sz parameters.
284 By default, session_shared will honor the paramters given by client.
285 An alternative, but not implemented, algorithm would be to only
286 re-use sessions with same sz parameters. This however, could reduce
287 re-use of sessions a lot. Hence this, simple algorithm instead. The
288 negotiation to a maximum sz values can be enabled by using
289 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
290 in configuration. This will make session_shared send those values
291 to backends and use returned init values in negotaition to
292 client before session_shared.
294 session_shared: resolve result-set references.
295 The reference is substitued with the query for old set if database
296 match and query type is Type-1. If not the reference will issue a
299 sort filter: relays RecordComposition including elementSet in use for
302 http_client: better diagnostics
304 http_client: disables HTTP redirect handling by default.
305 It can be configured with max-redirects in configuration.
307 --- 1.3.58 2013/06/12
309 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
311 --- 1.3.57 2013/06/12
313 Make RouterChain and RouterXML part of public API (libmetaproxy).
315 http_client: honor X-Metaproxy-Proxy as an alternative to
316 the "proxy" configuration. Allows proxy to be set per HTTP request.
318 sru_z3950: For SRU requests recognize x-client prefixes as a way
319 to ingest "database parameters".. The suffix of x-client- serves
320 as database argument name. Multiple may be given. For example:
321 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
322 is turned into Z39.50 database
325 --- 1.3.56 2013/05/27
327 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
329 New filter sd_remove, which replaces surrogate diagnostics with
330 SUTRS records. This filter tries to deal with clients that breaks
331 when receiving surrogate diagnostics.
333 new filter http_client. Same role as z3950_client, but just for
334 HTTP. Allows Metaproxy to operate as a HTTP proxy.
336 New filter http_rewrite1, which serves as purpose on how to rewrite
337 HTTP content with Metaproxy.
339 Use libboost-system if available, because newer versions of libboost-threads
340 requires libboost-system.
342 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
345 --- 1.3.55 2013/04/10
347 zoom: Torus setting: authenticationMode which may hold values "basic"
350 --- 1.3.54 2013/03/27
352 configure: check for Libxslt support in YAZ and rely on definitions
353 from yaz-config, rather than doing own xslt/xml2 checks.
355 Allow timestamp format for log lines to be given with option -m
356 for metaproxy. Similar to yaz-ztest/GFS option -m.
358 Document log category 'line' for log filter.
360 Solr configuration example in etc/config-solr.xml
362 multi: do not mess with request package. For scan and search,
363 database-names were modified and the request package was left with
364 dangling pointers that caused a log filter to fail (request package
365 inspected after multi was invoked).
367 Documentation: fix id of metaproxy-config ref .
369 Documentation: update for USEMARCON support.
371 --- 1.3.53 2013/01/31
373 record_transform: allow OPACXML to OPAC conversion
375 zoom: document content-proxy
377 zoom: document db parm content-{user,password}, torus_url. Also
378 <torus auth_url="..> which makes zoom operate in authenticated mode
381 --- 1.3.52 2012/11/30
383 zoom: fix http://-check. SRU search broken in 1.3.51.
385 --- 1.3.51 2012/11/15
387 zoom: only append http:// for SRU if not already given . Makes it
388 possible to use https-URLs.
390 Use yazpp 1.4 or later due to new ABI.
392 frontend_net: allow max package size to be specified. Controlled by
393 attribute 'max_recv_bytes' of element 'port'.
395 --- 1.3.50 2012/10/29
397 For most generated diagnostics by filters, typically temporary
398 system error, augment addinfo message with filter name.
400 Add support for CentOS 6 packages.
402 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
404 Add man page for metaproxy-config.
406 --- 1.3.49 2012/10/18
408 zoom: new config element passthru. This defines an element set that is
409 passed verbatim to the backend in pz2 mode.
411 auth_simple: allow both idPass and open auth. Also fix SEGV that could
414 --- 1.3.48 2012/10/08
416 z3950_client: fix string handling for init diagnostics in the case where
419 query_rewrite: no charset conversion for error queries. Avoid performing
420 charset conversion for query conversion errors. The resulting Type-1
421 query is invalid in this case.
423 --- 1.3.47 2012/10/04
425 For graceful stop (SIGUSR1), metaproxy will kill children processes.
427 Log when metaproxy is invoked in test mode (-t).
429 Log PID for each log message.
431 multi: combine both NSDs and multiple NSDs into one (diagnostics).
433 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
434 a (backend=target) is appended for each diagnostic so that can be
435 determined the origin of error.
437 multi: hideerrors also in use for present response.
439 Solr example in zoom man page.
441 Fix typo in query_rewrite config example.
443 Log at least first non surrogate diagnostic. Instead of
444 "Z_Records_multipleNSD"
446 multi: Fix check for opt Records in present response. A SEGV could occur
447 if a target did not return records and no diagnostics.
449 --- 1.3.46 2012/09/24
451 Yet another fix for graceful stop.
453 --- 1.3.45 2012/09/12
455 sru_z3950: relay surrogate diagnostics.
457 --- 1.3.44 2012/09/10
459 zoom: Honor extraArgs, strip # in zurl.
461 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
463 zoom: url_recipe allow %{var[reg]} substitutions.
464 It's like ${var[reg]} but does URI component encoding as well.
466 --- 1.3.43 2012/08/22
468 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
469 non-keepalive HTTP sessions.
471 http_file: allow zero size files (bug fix)
473 Fix zoom schema: auth_url is optional
475 --- 1.3.42 2012/08/20
477 zoom: fix un-init memory (could result in SEGV at session close)
479 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
480 and may be used in filters as usual.
482 zoom: authentication via Torus lookup
483 Enabled by new configuration setting: auth_url . If this is defined,
484 the zoom module will contact Torus for auth/IP lookup and that will
485 define realm to be used in session.
487 --- 1.3.41 2012/08/10
489 virt_db: Fix database name - first character we removed by mistake.
490 Bug introduced in 1.3.40.
492 --- 1.3.40 2012/08/06
494 virt_db: Don't use "unix path" as database for Unix sockets.
496 --- 1.3.39 2012/08/02
498 z3950_client: Don't tamper with / in zurl - fixes problems
499 using Unix sockets for backends.
501 session_shared: fix integer overflow problem with hit count.
503 session_shared: avoid long usage of cached queries.
505 zoom: New database argument , torus_url to set URL of Torus
506 record to be fetched.
508 --- 1.3.38 2012/07/04
510 Fixes for 'metaproxy reload' for RPM/Debian packages.
512 zoom: Allow rpn2cql conversion to be augmented with a properties file.
513 Element rpn2cql can be specified per-target for the zoom filter.
515 log: New category "line" which is a single-line log message with
516 most important parts of a HTTP/Z39.50 request/response.
518 --- 1.3.37 2012/06/01
520 frontend_net: add facility to report live statistics about response
521 times and current thread usage. The report is an XML document
522 and is triggered for a specific URL path. This is set by <stat-req>
523 in the configuration of frontend_net. By default this report is
524 disabled (same as empty value for <stat-req>).
526 Fix reload problem in init.d script for RPM/Debian.
527 The '/etc/init.d/metaproxy reload' in some cases would stop but not
528 start metaproxy - effectively stopping the service.
530 Don't display start log message when config testing (-t).
532 zoom: avoid CCL message limit of 1K in ZOOM filter.
534 --- 1.3.36 2012/05/10
536 metaproxy init script reacts to reload which does graceful stop +
537 start and is used by logrorate script.
539 --- 1.3.35 2012/05/09
541 Fixes for Windows compilation.
543 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
544 existing sessions running but terminate the monitor process that is
545 used in keepalive mode.
547 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
548 before. Consistent with 'metaproxy stop' message.
550 zoom: document zoom's proxy_timeout
552 z3950_client: fixup addinfo for init response
554 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
555 "Access to specified database denied" is returned, but only if init
556 response from backend does not carry diagnostics already.
558 multi: relays user info for first rejected target. The other-information
559 field for init response for first rejected target is in common init
560 response. This ensures that some backend init diagnostics are returned to
563 --- 1.3.34 2012/04/25
565 frontend_log: extend logging (when message is given in config).
567 --- 1.3.33 2012/04/25
569 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
571 --- 1.3.32 2012/04/24
573 sru_z3950 filter passes through incoming Z39.50 requests again. Was
574 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
576 --- 1.3.31 2012/04/24
578 zoom: fixes for retry/proxy failover logic. More logging.
580 --- 1.3.30 2012/04/23
582 zoom: return addinfo="proxy failure" for proxy failures. This also
583 changes the scheme for dealing with proxies a bit. zoom now always
584 do proxy check, even if there's no failover. Fortunately, that's not
587 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
588 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
589 generic. We don't know why the init would fail; IP, user, block IP, etc.
590 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
592 zoom: guess if invalid SRU response was an auth failure
594 session_shared: disable session retry by default . Can be enabled by
595 restart="true" in resultset section.
597 --- 1.3.29 2012/04/18
599 zoom: may read cf-proxy's config settings.
600 This reduces manual configuration of the content proxy server host.
601 The ZOOM module will use the old style session.proxyhost if "server"
602 is given (deprecated) and use the new style proxyhost/session if
603 "config_file" is in use.
605 frontend_net: remove incoming requests that can not be handled
606 Requests in queue for filter frontend_net are removed if client
607 closes connection for the session and request is not yet handled.
609 sru_z3950: serialize requests. This is to ensure that pipelined
610 HTTP requests are handled properly.
612 --- 1.3.28 2012/04/04
614 New class, wrbuf, that wraps YAZ' WRBUF.
616 --- 1.3.27 2012/03/30
618 Metaproxy daemon is now running as user "metaproxy". This user is
619 managed by package maintainer scripts. The user information is stored
620 in /etc/metaproxy/metaproxy.user .
622 --- 1.3.26 2012/03/20
624 New filter, sort, that allows sorting of XML records via Z39.50
627 Filter record_transform: USEMarcon support. For example:
628 <retrieval syntax="usmarc">
629 <backend syntax="unimarc" name="F">
630 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
634 Filter multi: empty route pattern uses route as default.
636 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
637 may use the shorter notation
638 <target route="z3950.indexdata.com"/>
640 Filter query_rewrite: use config path to locate XSLT.
642 Filter frontend_net: log statistics.
643 If a custom message element in frontend_net configuration it makes
644 the frontend_net filter produce a log entry whenever an operation
645 is completed. The log is always written using yaz_log with the
646 custom message given, the package ID (session ID) , the time
647 the operation has been active (end-to-end) , the threads currently
648 active/total and the size of the request input/output queues.
650 query_rewrite: charset conversion of query terms.
651 This is an optional feature. Enabled by element <charset> in
652 configuration with attribute 'from' and 'to' that specifies
653 from/to encodings. The default 'from' encoding is UTF-8.
655 Filter record_transform: honor piggyback searches.
657 Filter zoom: re-connect when database is reused.
658 Re-connect is necessary if a connection is lost or a timeout occurs.
659 If not, we'll be seeing zero hits, when we shouldn't.
661 --- 1.3.25 2012/02/29
663 zoom: Change scheme for dealing with content proxy URLs. The module
664 now has its own common XSL transform that is enabled by record_xsl
665 attribute in the configuration. This XSL gets parameter cproxyhost
666 that holds the host for the content proxy session . The genearted-url
667 is created only if urlRecipe is enabled. In previous version default
668 value of urlRecipe was ${md-electronic-url}; it is now empty and
669 disabled by default. Also generated-url no longer includes the content
670 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
673 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
674 connections. Default value is 40 (seconds).
676 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
677 "Malformed query" for syntax errors and related ones; throw
678 Bib-1: 3 "Unsupported search" for everything else. Details from
679 the CCL parser is provided as additional-info.
681 multi: new setting hideerrors that makes multi only relay diagnostics
682 to a client if all backends fail.
684 --- 1.3.24 2012/02/23
686 zoom: empty ccl_map field-mappings disables CCL map.
688 zoom: fix Explain search that could return error if session was
691 --- 1.3.23 2012/02/10
693 zoom: returns Explain records for database IR-Explain---1. The
694 target profile records are converted to Explain records via XSLT.
696 session_shared: make error recovery configurable. Whether a search
697 is restarted on errors or not, is configurable by attribute "restart"
698 in element "resultset" in configuration.
700 session_shared: only relay init for first request. session_shared, for
701 each backend class, now only relays first init request (rather than all).
702 The module only needs to save init response info once. This avoids the
703 need to check for session max.
705 --- 1.3.22 2012/02/02
707 zoom: fix memory leaks.
709 session_shared: maximum number of sessons is configurable. Default
710 value is 100. Result-sets for backends without named result sets are
711 only re-used if databases is identical for a search. This is under the
712 assumption that performance may suffer for those backends when
713 changing the database for each search.
715 multi: combines diagnostics from all backends. All diagnostics from
716 backends are combined into multiple non-surrogate diagnostics; rather
717 than just one diagnostic from first backend.
719 --- 1.3.21 2011/12/27
721 zoom: relay realm to cproxy parameter file.
723 Configuration: Allow filter collection element inside route. This
724 makes it possible to include multiple filters at once.
726 zoom: nocproxy also disables urlRecipe.
728 --- 1.3.20 2011/12/21
730 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
731 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
732 90: "Unsupported direction value".
734 zoom: honor database argument nocproxy. This disables creating a content
735 connector session (for non-CF targets, usually) and also relays nocproxy
736 as database argument to a CF target.
738 --- 1.3.19 2011/12/16
740 zoom: Multiple proxy hosts may be given for proxy rich database
741 parameter. List is comma separated.
743 http_file: decodes URI paths properly. Does not return 404: not found
744 if no prefix are matches. Instead packages are passed on.
746 --- 1.3.18 2011/12/08
748 zoom: content-{user,password,proxy} are passed on to content proxy
749 system and takes precedence over user,password,proxy .
751 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
752 with a log element including log material from children filters. At
753 this point, only the zoom filter uses this log facility. It will
754 eventually be used by other filters as well. In particular it might be
755 useful for this feature to track all filters in used during a search.
757 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
758 and queries as they are manipulated are logged.
760 zoom: extend addinfo with native diagnostics. Diagnostics as received
761 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
762 diagnostics. This indicates both a backend diagnostic and the original
765 zoom: default urlRecipe value is ${md-electronic-url}
767 zoom: target profile setting sruVersion is recognized.
769 --- 1.3.17 2011/11/17
771 zoom: log target profile record fetched (AKA Torus).
773 --- 1.3.16 2011/11/17
775 Change target profile parameter CfSubDb to CfSubDB.
777 --- 1.3.15 2011/11/12
779 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
780 makes sense to the zoom module itself).
782 --- 1.3.14 2011/11/11
784 zoom: realm may be given as part of database.
786 --- 1.3.13 2011/10/26
788 Fix Origin class assigment method; was removd by mistake in 1.3.12.
790 --- 1.3.12 2011/10/26
792 zoom: database args x-name=value are passed through to backend database.
794 SRU filter: user may specify session ID that is passed to log entries
795 that follows. It is specified by using x-session-id in the SRU arguments.
797 zoom: fix null pointer reference which would occur for bad url parameter
798 inside "torus" or if url was not given.
800 --- 1.3.11 2011/09/09
801 Fix bug in filter session_shared where sessions would not expire
802 properly (session ttl). This in turn could make the target close the
803 connection before expected and session_shared would return diagnostic
804 2: system temporarily available.
806 --- 1.3.10 2011/09/09
808 zoom: new target profile setting: sortmap_field. If sortmap_field is given
809 the field is mapped to the value for the sortmap. Values not matching
810 sortmap_field are passed verbatim.
812 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
813 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
814 depending on whether RPN or CQL is actually sent to the target.
818 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
820 zoom: For content proxy authentication is stored in param name
821 "auth", instead of "authentication".
825 zoom: relay schema in SRU mode. Previously recordSchema was not affected
830 zoom: new target profile element literalTransform that holds XSLT
831 (encoded as string) for target. Only if present and non-zero length it is
832 considered present. This takes precedence over transform.
834 Don't rely on trang anymore for Git checkout builds. Configuration in etc
835 will only be properly validated if trang is available. From now on only
836 relax NC files are bundled with the source dist.
838 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
839 component was not detected when it should be.
843 z3950_client: mark non-surrogate diagnostics from backend.
845 zoom: a proxy may be specified for HTTP fetch of target profiles.
849 Honor piggyback. Makes some SRU targets behave that insist on
850 maximumRecords > 0, but also increases performance.
854 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
855 file was not update for libdir/metaproxy4 in version 1.3.2.
859 Change location of Metaproxy modules from libdir/metaproxy to
860 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
861 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
863 New facility to dump APDUs from zoom filter. Enabled by
864 <log apdu="true"/> in the zoom filter configuation.
866 zoom filter bug fix: SRU diagnostics received from backend was
867 not properly converted to Bib-1 diagnostics.
869 Package metaproxy depends on libmetaproxy4, same version.
873 zoom: fix a bug WRT passing authentication parameters to backends.
877 Fixes for windows Makefile.
879 --- 1.2.10 2011/07/25
881 Change major version of metaproxy library from 3 to 4. This in turn
882 makes new package names for Debian and RPM.
886 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
889 zoom: configurable element sets for record transforms.
891 zoom: the target profile based transform is specified by element_transform
892 in element torus of of the ZOOM filter configuration ; default value
893 is "pz2". Target profile based retrieval is specified by element_raw
894 in configuration. It will perform same steps, but omit the XSL transform.
895 Default value is "raw".
897 zoom: element set is omitted if not set in profile. But only if pz2
898 transform is in effect. Previously the default element set was to "F".
900 zoom: For non-CF targets database arguments are parsed. User may supply
901 db,user=myuser&password=mypass for non-CF targets. These values override
902 what's given the authentication from the target profile.
904 session_shared: fix reference to freed memory. Would occur if a search
905 response had non-surrogate diagnostics.
909 Route may be given for each port in frontend_net.
913 Documentation for zoom filter. Local target profiles may be specified.
915 Fixes for zoom filter.
919 First version with zoom filter.
923 Filter z3950_client may be configured to always send a close APDU
924 to backend target when connection/session is closed. This will only
925 happen if close APDU is not already sent. Enabled by configuration
926 for z3950_client (force_close).
928 Filter virt_db and multi: relay close APDU.
930 Filter virt_db and multi: relay init size parameters
931 preferredMessageSize and maximumRecordSize.
933 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
937 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
939 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
940 as determined by configure.
942 RPM: Release includes 'indexdata' name. Use indexdata in release name so
943 this package can be distinguished from other vendors.
947 Fix filter multi: relay idAuthentication parameters.
951 Add metaproxy-config for returning compiler flags, libraries.
955 Fix --with-boost=PREFIX .
959 session_shared: fix use of maintenance thread.
961 Introduce 'start' method for filters and routers. It gets called after
962 configure and after fork, but before processing. This changes API -
963 from libmetaproxy2 to libmetaproxy3.
967 session_shared: ensure backend session is closed if init rejected
970 z3950_client: fix NULL ptr reference that could occur if two clients
971 connected concurrently and if max-sockets was in effect.
975 Fix bug 3497 - Metaproxy unstable while stopping.
977 Fix bug 3495 - SEGV in SRU filter.
981 Filter multi throws diagnostic 'Present Out of Range' when
982 appropriate - rather than returning 0 records.
984 Filter virt_db: fix bad result reuse. Could happen if a result
985 was overriden and a backend did not supported named result sets.
989 Filter log: category access logs diagnostics even if searchStatus
990 or presentStatus is 'success'.
994 The SRU to Z39.50 filter does repeated Z39.50 present requests
995 to fetch all records. Needed when a Z39.50 server returns partial
996 results (due to message size limits).
1000 Metaproxy now kills all child processes that are spawned by
1001 modules (in case of fork, exec).
1003 --- 1.1.1 2010/01/28
1005 Debian package now installs /etc/metaproxy/metaproxy.xml which
1006 includes all XML files /etc/metaproxy/filters-enabled .
1007 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1009 --- 1.1.0 2010/01/20
1011 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1012 development package to facilitate 3rd party Metaproxy modules.
1014 --- 1.0.23 2010/01/04
1016 Filter virt_db: Close backend filter session when Init rejected is received
1017 from it (in which case it's not really closed yet). This will ensure we don't
1018 run out of resources such as FDs in this case.
1020 sru_z3950 filter: Accept any database (including those not listed).
1022 --- 1.0.22 2009/12/03
1024 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1025 later which means YAZ 3.0.47 or later.
1027 --- 1.0.20 2009/11/19
1029 For filter virt_db, the database is a glob pattern and the virtual
1030 database sections are consulted in the order given.
1032 --- 1.0.19 2009/07/08
1034 For filter multi, the target (for routing) may be given as a glob-pattern.
1036 More documentation for filters virt_db and multi.
1038 Update schema to allow for no database in sru_z3950 filter.
1040 --- 1.0.18 2009/06/30
1042 Added limit filter to put sleep (penalty) for heavy use.
1044 Filter frontend_net may be configured to limit the number of new connections
1045 from same IP to some value (connect-max).
1047 Fixed the load_balance filter.
1049 --- 1.0.17 2009/06/16
1051 Fix path for metaproxy executable for Debian init.d script.
1053 --- 1.0.16 2009/06/10
1055 SRU to Z39.50 filter honors x-username and x-password. If only
1056 x-username is given that translates to open authentication (Z39.50v2). If
1057 both x-username and x-password is present that translates to idPass
1058 authentication (Z39.50v3).
1060 New facility to change current working directory (-w).
1062 Update to upstream skeleton of init.d script. Should fix bug #2619.
1064 Filter session_shared now caches records (used to only cache connections
1067 Filter session_shared now invalidates a Z39.50 session if a server
1068 returns -1 hits. This facility was also part of yazproxy and gets around
1069 a bug in Voyager-based Z39.50 servers.
1071 --- 1.0.15 2008/11/18
1073 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1075 --- 1.0.14 2008/06/09
1077 Fixed the value of SRU record schema in searchRetrieve response. It was set
1078 to a fixed value of "dc" before.
1080 Serialize identical SRU requests. This is useful if HTTP client software
1081 fires identical requests against metaproxy.
1083 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1084 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1085 avoid static configuration. This facility is handled by the sru_z3950 module
1086 and the z3950_client module.
1088 Allow maximum number of sockets to be used for a Z39.50 client by the
1089 use of SRU extra parameter x-max-sockets. This facility is handled by the
1090 sru_z3950 module and the z3950_client module.
1092 --- 1.0.13.1 2008/02/29
1094 Simplified check for Boost libraries.
1096 --- 1.0.13 2008/02/29
1098 First Debian package.
1100 The sru_z9350 filter now recognizes SRU parameter z-target as being
1101 a ZURL of the form host/database .
1103 Mergetype may be specified for filter 'multi'.
1105 --- 1.0.12 2007/09/19
1107 Fixed problem in Makefile WRT library specifictions. This could produce
1108 linker errors (when they should not happen).
1110 Fixed bug #1341: MetaProxy returning different results. Problem was that
1111 fix-up of record database did not normalize the database name.
1113 Documentation updates for Windows compilation.
1115 --- 1.0.11 2007/06/14
1117 Fixed problem with logfile being truncated.
1119 --- 1.0.10 2007/05/23
1121 Fixed bug #1136: Access rights not enforced.
1123 Extension for log module. The log category 'access' logs more details.
1124 New category 'user-access' added which is simlar to 'access' but adds
1125 the Z39.50 user as for all entries in a session.
1129 Added support for configurable default/force target/vhost for module Z39.50
1132 --- 1.0.8 2007/01/25
1134 Implemented filter, session_shared, which optimizes usage of Z39.50
1135 sessions and result sets.
1137 New filter, record_transform, which converts MARC/XML records.
1139 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1141 New filter, load_balance, in development.
1143 New filter, zeerex_xplain.
1145 XML framework for config files started.
1147 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1148 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1149 XML config files are checked against RNG and XML Schema's.
1151 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1152 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1153 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1154 explain record to YAZ CQL-to-PQF text config file.
1156 --- 1.0.7 2006/11/07
1158 Added 'timeout' setting for filter frontend_net which specifies the number
1159 of seconds a session is idle before it is closed. Default timeout is
1162 --- 1.0.6 2006/07/07
1164 Database name in records returned set for virt_db/multi filters.
1166 Filter session_shared now functional.
1168 Log filter can be configured to write to a given file using 'filename'
1169 element. Also information category can be specified with 'category'. If
1170 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1173 --- 1.0.5 2006/05/16
1175 Fixed compilation on Windows.
1177 --- 1.0.4 2006/05/16
1179 Added documentation for the hidenavailable option for the multi filter.
1181 --- 1.0.3 2006/05/16
1183 Fixed bug #573: Hide errors for individual servers. If the element
1184 'hideunavailable' is given in the configuration, individual servers
1185 being unavailable are hidden (unless all are unavailable).
1187 Fixed bug #574: Database names are recognised case-sensitively.
1189 Fixed bug #567: Fix up database name in Name-Plus-Record.
1191 Fixed bug #568: Update win/makefile for VS 2005.
1193 Fixed bug #569: Some options throws unknown exception.
1195 --- 1.0.2 2006/04/28
1197 More information about virtual hosts. The 'etc' directory is part of the
1200 --- 1.0.1 2006/04/27
1202 Build instructions for Windows. NMake makefile part of distribution tar.
1204 --- 1.0.0 2006/04/24
1208 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1209 log, multi, query_rewrite, template, virt_db, z3950_client.
1211 Filters in development: session_shared.
1213 Pseudo-filters: template, dl
