3 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
7 session_shared: close in ~BackendInstance MP-549
8 This fixes a serious issue where some MP would leak sockets.
10 session_shared: mutex lock in BackendClass::release_backend MP-550
11 Fixes a SEGV that could occur (in rare cases).
15 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
17 zoom: fix invalid present response in some cases MP-546
19 zoom: Relay Torus HTTP error message
23 Check for proper limits before using RecordCache functions MP-544
27 Build packages for Ubuntu Trusty Tahr 14.04 LTS
29 sort: crash / invalid_read in filter sort MP-541
31 sru_z3950: facet should be stored in additionalSearchInfo MP-533
33 doc: fix missing man pages MP-542
35 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
37 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
41 sru_z3950: fix facet response (memory corruption) MP-532
43 log: fix crash idPass user is omitted MP-530
47 query_rewrite: pass-thru non Type-1 queries MP-527
49 metaproxy stop (SIGTERM) kills all child processes spanwed by
50 filter (if any) before invoking filter destructors. MP-525
54 http_file: only supports HTTP GET MP-523
56 session_shared: shut down expire thread in destructor
57 This ensures that expire thread is not running after destruction
58 and does bad memory references, etc.
60 frontend_net: fix segfault on startup MP-524
61 Would happen if MP was listening on multiple ports and one
62 of the ports was already in use (and MP would exit).
64 frontend_net: fix memory leak MP-521
65 This leak would occur if all sessions were in use and the input
66 queue was cleared when a client would close connection (socket).
68 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
72 http_rewrite: use local skiplist; fixes memory corruption. MP-520
74 http_client: x-forwarded-for controls X-Forwarded-For presence
75 If x-forwarded-for setting (boolean) is enabled, http_client will
76 generate an X-Forwarded-For header entry which includes existing
77 X-Forwarded-For (if any) and current peer address (immediate client
78 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
79 will not be generated.
81 z3950_client: client_ip controls client-IP presence
82 If client_ip setting (boolean) is enabled, z3950_client will
83 generate a client_ip OID as part of init request which includes
84 previous client_ip (if any) and current peer address (immediate
85 client of Metaproxy). By default client_ip is disabled and client_ip
86 will not be generated.
88 HTTP X-Forwarded-For/Z39.50 Client-IP support
89 virt_db, multi: relays Z39.50 client-IP.
90 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
91 zoom: uses Client-IP or origin address (prefer Client-IP).
92 frontend_net: Strips tcp: from peer address (so that it is no longer
93 printed and stripped in zoom filter).
94 z3950_client: builds client-IP list - combining immediate peer address
95 as returned by COMSTACK and existing client-IP list (if avaiable).
96 The Origin only printes first X-Forwarded address.
100 Log when SIG{TERM,USR1} is received ASAP MP-513
101 Do it in frontend_net event loop rather than in place for metaproxy
102 main, which only exits when all sessions are terminated for SIGUSR1
105 metaproxy-config: quote some RHS values (that might include blanks)
107 Fix leak in sru_z3950 filter - when explain is returned MP-511
109 Allow stylesheet to be given for sru_z3950 filter MP-510
110 This is based on a patch by Sven Porst and the functionality
111 of the YAZ Generic Frontend Server.
113 Allow base attribute in configuration file tags - the attributes are
114 inserted by XInclude usage as mentioned on
115 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
116 and noted in a gist: https://gist.github.com/3551094
118 Package metaproxy provides virtual package metaproxy6 MP-508
119 This allows module packages to depend on a metaproxy server
122 Filter destructors called upon daemon termination MP-505
123 When metaproxy daemon receives SIGTERM the stop method of each filter
124 is called. The stop method existed before, but did not take any
125 arguements (void).. The frontend_net filter can now distinguish
126 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
127 (stop immediately). Note that this changes the API+ABI of Metaproxy
130 zoom: sync up with Pazpar2 WRT authentication handling MP-492
132 Router: use shared_ptr rather than naked one - to avoid leak if an
133 exception is thrown in configure.
137 zoom: Add nocproxy=1 for contentConnector sessions MP-501
139 Doc: mention proper versions; fix link to Boost win binaries.
141 Windows: update for Boost 1.55
143 Windows: avoid warning when using boost::split. Done by defining
144 _SCL_SECURE_NO_WARNINGS for Visual Studio.
146 Fix LSB conformance for /etc/init.d/metaproxy MP-500
147 Debian: add support for /etc/init.d/metaproxy status
149 sort: Add const to Record less than operator in order to compile on
154 session_shared: fix element-set handling in record caching. MP-499
156 document http_rewrite. MP-468
158 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
159 respects the header (which will normally come from the cproxy filter)
163 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
164 RPM was unsable in version 1.4.0.
166 Remove log message about "backend classes". Appeared in version 1.4.0.
170 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
171 with older version from source, but packages now use YAZ 5 that supports
174 sru_z3950: Fix SEGV for decoding invalid SRU requests
175 Incorrect reference to union (was explain response rather than
178 session_shared: match additionalSearchInfo (includes facets). In
179 layman's terms means that means that facets are properly handled
180 by this filter. Eg a change in requested facets will issue new
181 search and facets from exisiting result set are cached.
183 --- 1.3.62 2013/09/11
185 http_rewrite: better handling of <script> content in HTML parser. MP-486
187 http_rewrite: fix threading issue with regex. MP-482
189 bounce: don't use strdup for fixed length content. Error occurred in echo
192 session_shared: expire backend class when no instances left. This
193 means memory clean up, but not really a leak fix.
195 virt_db: fix leak for naked ptr.
197 cql_rpn: use config relative path for cql2rpn file. MP-481
199 Updates for upcoming YAZ 5.
201 --- 1.3.61 2013/08/29
203 New configuration directories ports.d/routes.d for metaproxy
204 configuration. This allows 3rd party packages to install config
205 for ports and new routes. MP-477
207 --- 1.3.60 2013/08/21
209 Fix metaproxy-config --libs to return non-mt over mt libs.
210 The -mt versions do not exist as shared objects and cause
211 linker errors for applications linking with Metaproxy.
212 Problem present in versions 1.3.56 - 1.3.59. MP-475
214 HTML: clean up char checks. Add ptr to HTML parse spec
216 HTML parser stops eating tag when <-char is met MP-473
218 rewrite: do not even compare content types, if we don't have any
219 the regex_match caused a segfault if we had no content-type in the
222 rewrite: within header=... matches only the header value
223 Used to match the whole header line, but we need to use
224 ^$ anchoring for host-relative regexps, and they need to
225 anchor at the ends of the value. MP-470.
227 rewrite: Ruleset functional MP-469
229 --- 1.3.59 2013/07/12
231 session_shared: negotiate init sz parameters.
232 By default, session_shared will honor the paramters given by client.
233 An alternative, but not implemented, algorithm would be to only
234 re-use sessions with same sz parameters. This however, could reduce
235 re-use of sessions a lot. Hence this, simple algorithm instead. The
236 negotiation to a maximum sz values can be enabled by using
237 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
238 in configuration. This will make session_shared send those values
239 to backends and use returned init values in negotaition to
240 client before session_shared.
242 session_shared: resolve result-set references.
243 The reference is substitued with the query for old set if database
244 match and query type is Type-1. If not the reference will issue a
247 sort filter: relays RecordComposition including elementSet in use for
250 http_client: better diagnostics
252 http_client: disables HTTP redirect handling by default.
253 It can be configured with max-redirects in configuration.
255 --- 1.3.58 2013/06/12
257 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
259 --- 1.3.57 2013/06/12
261 Make RouterChain and RouterXML part of public API (libmetaproxy).
263 http_client: honor X-Metaproxy-Proxy as an alternative to
264 the "proxy" configuration. Allows proxy to be set per HTTP request.
266 sru_z3950: For SRU requests recognize x-client prefixes as a way
267 to ingest "database parameters".. The suffix of x-client- serves
268 as database argument name. Multiple may be given. For example:
269 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
270 is turned into Z39.50 database
273 --- 1.3.56 2013/05/27
275 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
277 New filter sd_remove, which replaces surrogate diagnostics with
278 SUTRS records. This filter tries to deal with clients that breaks
279 when receiving surrogate diagnostics.
281 new filter http_client. Same role as z3950_client, but just for
282 HTTP. Allows Metaproxy to operate as a HTTP proxy.
284 New filter http_rewrite1, which serves as purpose on how to rewrite
285 HTTP content with Metaproxy.
287 Use libboost-system if available, because newer versions of libboost-threads
288 requires libboost-system.
290 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
293 --- 1.3.55 2013/04/10
295 zoom: Torus setting: authenticationMode which may hold values "basic"
298 --- 1.3.54 2013/03/27
300 configure: check for Libxslt support in YAZ and rely on definitions
301 from yaz-config, rather than doing own xslt/xml2 checks.
303 Allow timestamp format for log lines to be given with option -m
304 for metaproxy. Similar to yaz-ztest/GFS option -m.
306 Document log category 'line' for log filter.
308 Solr configuration example in etc/config-solr.xml
310 multi: do not mess with request package. For scan and search,
311 database-names were modified and the request package was left with
312 dangling pointers that caused a log filter to fail (request package
313 inspected after multi was invoked).
315 Documentation: fix id of metaproxy-config ref .
317 Documentation: update for USEMARCON support.
319 --- 1.3.53 2013/01/31
321 record_transform: allow OPACXML to OPAC conversion
323 zoom: document content-proxy
325 zoom: document db parm content-{user,password}, torus_url. Also
326 <torus auth_url="..> which makes zoom operate in authenticated mode
329 --- 1.3.52 2012/11/30
331 zoom: fix http://-check. SRU search broken in 1.3.51.
333 --- 1.3.51 2012/11/15
335 zoom: only append http:// for SRU if not already given . Makes it
336 possible to use https-URLs.
338 Use yazpp 1.4 or later due to new ABI.
340 frontend_net: allow max package size to be specified. Controlled by
341 attribute 'max_recv_bytes' of element 'port'.
343 --- 1.3.50 2012/10/29
345 For most generated diagnostics by filters, typically temporary
346 system error, augment addinfo message with filter name.
348 Add support for CentOS 6 packages.
350 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
352 Add man page for metaproxy-config.
354 --- 1.3.49 2012/10/18
356 zoom: new config element passthru. This defines an element set that is
357 passed verbatim to the backend in pz2 mode.
359 auth_simple: allow both idPass and open auth. Also fix SEGV that could
362 --- 1.3.48 2012/10/08
364 z3950_client: fix string handling for init diagnostics in the case where
367 query_rewrite: no charset conversion for error queries. Avoid performing
368 charset conversion for query conversion errors. The resulting Type-1
369 query is invalid in this case.
371 --- 1.3.47 2012/10/04
373 For graceful stop (SIGUSR1), metaproxy will kill children processes.
375 Log when metaproxy is invoked in test mode (-t).
377 Log PID for each log message.
379 multi: combine both NSDs and multiple NSDs into one (diagnostics).
381 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
382 a (backend=target) is appended for each diagnostic so that can be
383 determined the origin of error.
385 multi: hideerrors also in use for present response.
387 Solr example in zoom man page.
389 Fix typo in query_rewrite config example.
391 Log at least first non surrogate diagnostic. Instead of
392 "Z_Records_multipleNSD"
394 multi: Fix check for opt Records in present response. A SEGV could occur
395 if a target did not return records and no diagnostics.
397 --- 1.3.46 2012/09/24
399 Yet another fix for graceful stop.
401 --- 1.3.45 2012/09/12
403 sru_z3950: relay surrogate diagnostics.
405 --- 1.3.44 2012/09/10
407 zoom: Honor extraArgs, strip # in zurl.
409 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
411 zoom: url_recipe allow %{var[reg]} substitutions.
412 It's like ${var[reg]} but does URI component encoding as well.
414 --- 1.3.43 2012/08/22
416 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
417 non-keepalive HTTP sessions.
419 http_file: allow zero size files (bug fix)
421 Fix zoom schema: auth_url is optional
423 --- 1.3.42 2012/08/20
425 zoom: fix un-init memory (could result in SEGV at session close)
427 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
428 and may be used in filters as usual.
430 zoom: authentication via Torus lookup
431 Enabled by new configuration setting: auth_url . If this is defined,
432 the zoom module will contact Torus for auth/IP lookup and that will
433 define realm to be used in session.
435 --- 1.3.41 2012/08/10
437 virt_db: Fix database name - first character we removed by mistake.
438 Bug introduced in 1.3.40.
440 --- 1.3.40 2012/08/06
442 virt_db: Don't use "unix path" as database for Unix sockets.
444 --- 1.3.39 2012/08/02
446 z3950_client: Don't tamper with / in zurl - fixes problems
447 using Unix sockets for backends.
449 session_shared: fix integer overflow problem with hit count.
451 session_shared: avoid long usage of cached queries.
453 zoom: New database argument , torus_url to set URL of Torus
454 record to be fetched.
456 --- 1.3.38 2012/07/04
458 Fixes for 'metaproxy reload' for RPM/Debian packages.
460 zoom: Allow rpn2cql conversion to be augmented with a properties file.
461 Element rpn2cql can be specified per-target for the zoom filter.
463 log: New category "line" which is a single-line log message with
464 most important parts of a HTTP/Z39.50 request/response.
466 --- 1.3.37 2012/06/01
468 frontend_net: add facility to report live statistics about response
469 times and current thread usage. The report is an XML document
470 and is triggered for a specific URL path. This is set by <stat-req>
471 in the configuration of frontend_net. By default this report is
472 disabled (same as empty value for <stat-req>).
474 Fix reload problem in init.d script for RPM/Debian.
475 The '/etc/init.d/metaproxy reload' in some cases would stop but not
476 start metaproxy - effectively stopping the service.
478 Don't display start log message when config testing (-t).
480 zoom: avoid CCL message limit of 1K in ZOOM filter.
482 --- 1.3.36 2012/05/10
484 metaproxy init script reacts to reload which does graceful stop +
485 start and is used by logrorate script.
487 --- 1.3.35 2012/05/09
489 Fixes for Windows compilation.
491 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
492 existing sessions running but terminate the monitor process that is
493 used in keepalive mode.
495 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
496 before. Consistent with 'metaproxy stop' message.
498 zoom: document zoom's proxy_timeout
500 z3950_client: fixup addinfo for init response
502 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
503 "Access to specified database denied" is returned, but only if init
504 response from backend does not carry diagnostics already.
506 multi: relays user info for first rejected target. The other-information
507 field for init response for first rejected target is in common init
508 response. This ensures that some backend init diagnostics are returned to
511 --- 1.3.34 2012/04/25
513 frontend_log: extend logging (when message is given in config).
515 --- 1.3.33 2012/04/25
517 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
519 --- 1.3.32 2012/04/24
521 sru_z3950 filter passes through incoming Z39.50 requests again. Was
522 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
524 --- 1.3.31 2012/04/24
526 zoom: fixes for retry/proxy failover logic. More logging.
528 --- 1.3.30 2012/04/23
530 zoom: return addinfo="proxy failure" for proxy failures. This also
531 changes the scheme for dealing with proxies a bit. zoom now always
532 do proxy check, even if there's no failover. Fortunately, that's not
535 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
536 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
537 generic. We don't know why the init would fail; IP, user, block IP, etc.
538 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
540 zoom: guess if invalid SRU response was an auth failure
542 session_shared: disable session retry by default . Can be enabled by
543 restart="true" in resultset section.
545 --- 1.3.29 2012/04/18
547 zoom: may read cf-proxy's config settings.
548 This reduces manual configuration of the content proxy server host.
549 The ZOOM module will use the old style session.proxyhost if "server"
550 is given (deprecated) and use the new style proxyhost/session if
551 "config_file" is in use.
553 frontend_net: remove incoming requests that can not be handled
554 Requests in queue for filter frontend_net are removed if client
555 closes connection for the session and request is not yet handled.
557 sru_z3950: serialize requests. This is to ensure that pipelined
558 HTTP requests are handled properly.
560 --- 1.3.28 2012/04/04
562 New class, wrbuf, that wraps YAZ' WRBUF.
564 --- 1.3.27 2012/03/30
566 Metaproxy daemon is now running as user "metaproxy". This user is
567 managed by package maintainer scripts. The user information is stored
568 in /etc/metaproxy/metaproxy.user .
570 --- 1.3.26 2012/03/20
572 New filter, sort, that allows sorting of XML records via Z39.50
575 Filter record_transform: USEMarcon support. For example:
576 <retrieval syntax="usmarc">
577 <backend syntax="unimarc" name="F">
578 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
582 Filter multi: empty route pattern uses route as default.
584 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
585 may use the shorter notation
586 <target route="z3950.indexdata.com"/>
588 Filter query_rewrite: use config path to locate XSLT.
590 Filter frontend_net: log statistics.
591 If a custom message element in frontend_net configuration it makes
592 the frontend_net filter produce a log entry whenever an operation
593 is completed. The log is always written using yaz_log with the
594 custom message given, the package ID (session ID) , the time
595 the operation has been active (end-to-end) , the threads currently
596 active/total and the size of the request input/output queues.
598 query_rewrite: charset conversion of query terms.
599 This is an optional feature. Enabled by element <charset> in
600 configuration with attribute 'from' and 'to' that specifies
601 from/to encodings. The default 'from' encoding is UTF-8.
603 Filter record_transform: honor piggyback searches.
605 Filter zoom: re-connect when database is reused.
606 Re-connect is necessary if a connection is lost or a timeout occurs.
607 If not, we'll be seeing zero hits, when we shouldn't.
609 --- 1.3.25 2012/02/29
611 zoom: Change scheme for dealing with content proxy URLs. The module
612 now has its own common XSL transform that is enabled by record_xsl
613 attribute in the configuration. This XSL gets parameter cproxyhost
614 that holds the host for the content proxy session . The genearted-url
615 is created only if urlRecipe is enabled. In previous version default
616 value of urlRecipe was ${md-electronic-url}; it is now empty and
617 disabled by default. Also generated-url no longer includes the content
618 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
621 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
622 connections. Default value is 40 (seconds).
624 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
625 "Malformed query" for syntax errors and related ones; throw
626 Bib-1: 3 "Unsupported search" for everything else. Details from
627 the CCL parser is provided as additional-info.
629 multi: new setting hideerrors that makes multi only relay diagnostics
630 to a client if all backends fail.
632 --- 1.3.24 2012/02/23
634 zoom: empty ccl_map field-mappings disables CCL map.
636 zoom: fix Explain search that could return error if session was
639 --- 1.3.23 2012/02/10
641 zoom: returns Explain records for database IR-Explain---1. The
642 target profile records are converted to Explain records via XSLT.
644 session_shared: make error recovery configurable. Whether a search
645 is restarted on errors or not, is configurable by attribute "restart"
646 in element "resultset" in configuration.
648 session_shared: only relay init for first request. session_shared, for
649 each backend class, now only relays first init request (rather than all).
650 The module only needs to save init response info once. This avoids the
651 need to check for session max.
653 --- 1.3.22 2012/02/02
655 zoom: fix memory leaks.
657 session_shared: maximum number of sessons is configurable. Default
658 value is 100. Result-sets for backends without named result sets are
659 only re-used if databases is identical for a search. This is under the
660 assumption that performance may suffer for those backends when
661 changing the database for each search.
663 multi: combines diagnostics from all backends. All diagnostics from
664 backends are combined into multiple non-surrogate diagnostics; rather
665 than just one diagnostic from first backend.
667 --- 1.3.21 2011/12/27
669 zoom: relay realm to cproxy parameter file.
671 Configuration: Allow filter collection element inside route. This
672 makes it possible to include multiple filters at once.
674 zoom: nocproxy also disables urlRecipe.
676 --- 1.3.20 2011/12/21
678 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
679 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
680 90: "Unsupported direction value".
682 zoom: honor database argument nocproxy. This disables creating a content
683 connector session (for non-CF targets, usually) and also relays nocproxy
684 as database argument to a CF target.
686 --- 1.3.19 2011/12/16
688 zoom: Multiple proxy hosts may be given for proxy rich database
689 parameter. List is comma separated.
691 http_file: decodes URI paths properly. Does not return 404: not found
692 if no prefix are matches. Instead packages are passed on.
694 --- 1.3.18 2011/12/08
696 zoom: content-{user,password,proxy} are passed on to content proxy
697 system and takes precedence over user,password,proxy .
699 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
700 with a log element including log material from children filters. At
701 this point, only the zoom filter uses this log facility. It will
702 eventually be used by other filters as well. In particular it might be
703 useful for this feature to track all filters in used during a search.
705 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
706 and queries as they are manipulated are logged.
708 zoom: extend addinfo with native diagnostics. Diagnostics as received
709 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
710 diagnostics. This indicates both a backend diagnostic and the original
713 zoom: default urlRecipe value is ${md-electronic-url}
715 zoom: target profile setting sruVersion is recognized.
717 --- 1.3.17 2011/11/17
719 zoom: log target profile record fetched (AKA Torus).
721 --- 1.3.16 2011/11/17
723 Change target profile parameter CfSubDb to CfSubDB.
725 --- 1.3.15 2011/11/12
727 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
728 makes sense to the zoom module itself).
730 --- 1.3.14 2011/11/11
732 zoom: realm may be given as part of database.
734 --- 1.3.13 2011/10/26
736 Fix Origin class assigment method; was removd by mistake in 1.3.12.
738 --- 1.3.12 2011/10/26
740 zoom: database args x-name=value are passed through to backend database.
742 SRU filter: user may specify session ID that is passed to log entries
743 that follows. It is specified by using x-session-id in the SRU arguments.
745 zoom: fix null pointer reference which would occur for bad url parameter
746 inside "torus" or if url was not given.
748 --- 1.3.11 2011/09/09
749 Fix bug in filter session_shared where sessions would not expire
750 properly (session ttl). This in turn could make the target close the
751 connection before expected and session_shared would return diagnostic
752 2: system temporarily available.
754 --- 1.3.10 2011/09/09
756 zoom: new target profile setting: sortmap_field. If sortmap_field is given
757 the field is mapped to the value for the sortmap. Values not matching
758 sortmap_field are passed verbatim.
760 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
761 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
762 depending on whether RPN or CQL is actually sent to the target.
766 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
768 zoom: For content proxy authentication is stored in param name
769 "auth", instead of "authentication".
773 zoom: relay schema in SRU mode. Previously recordSchema was not affected
778 zoom: new target profile element literalTransform that holds XSLT
779 (encoded as string) for target. Only if present and non-zero length it is
780 considered present. This takes precedence over transform.
782 Don't rely on trang anymore for Git checkout builds. Configuration in etc
783 will only be properly validated if trang is available. From now on only
784 relax NC files are bundled with the source dist.
786 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
787 component was not detected when it should be.
791 z3950_client: mark non-surrogate diagnostics from backend.
793 zoom: a proxy may be specified for HTTP fetch of target profiles.
797 Honor piggyback. Makes some SRU targets behave that insist on
798 maximumRecords > 0, but also increases performance.
802 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
803 file was not update for libdir/metaproxy4 in version 1.3.2.
807 Change location of Metaproxy modules from libdir/metaproxy to
808 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
809 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
811 New facility to dump APDUs from zoom filter. Enabled by
812 <log apdu="true"/> in the zoom filter configuation.
814 zoom filter bug fix: SRU diagnostics received from backend was
815 not properly converted to Bib-1 diagnostics.
817 Package metaproxy depends on libmetaproxy4, same version.
821 zoom: fix a bug WRT passing authentication parameters to backends.
825 Fixes for windows Makefile.
827 --- 1.2.10 2011/07/25
829 Change major version of metaproxy library from 3 to 4. This in turn
830 makes new package names for Debian and RPM.
834 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
837 zoom: configurable element sets for record transforms.
839 zoom: the target profile based transform is specified by element_transform
840 in element torus of of the ZOOM filter configuration ; default value
841 is "pz2". Target profile based retrieval is specified by element_raw
842 in configuration. It will perform same steps, but omit the XSL transform.
843 Default value is "raw".
845 zoom: element set is omitted if not set in profile. But only if pz2
846 transform is in effect. Previously the default element set was to "F".
848 zoom: For non-CF targets database arguments are parsed. User may supply
849 db,user=myuser&password=mypass for non-CF targets. These values override
850 what's given the authentication from the target profile.
852 session_shared: fix reference to freed memory. Would occur if a search
853 response had non-surrogate diagnostics.
857 Route may be given for each port in frontend_net.
861 Documentation for zoom filter. Local target profiles may be specified.
863 Fixes for zoom filter.
867 First version with zoom filter.
871 Filter z3950_client may be configured to always send a close APDU
872 to backend target when connection/session is closed. This will only
873 happen if close APDU is not already sent. Enabled by configuration
874 for z3950_client (force_close).
876 Filter virt_db and multi: relay close APDU.
878 Filter virt_db and multi: relay init size parameters
879 preferredMessageSize and maximumRecordSize.
881 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
885 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
887 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
888 as determined by configure.
890 RPM: Release includes 'indexdata' name. Use indexdata in release name so
891 this package can be distinguished from other vendors.
895 Fix filter multi: relay idAuthentication parameters.
899 Add metaproxy-config for returning compiler flags, libraries.
903 Fix --with-boost=PREFIX .
907 session_shared: fix use of maintenance thread.
909 Introduce 'start' method for filters and routers. It gets called after
910 configure and after fork, but before processing. This changes API -
911 from libmetaproxy2 to libmetaproxy3.
915 session_shared: ensure backend session is closed if init rejected
918 z3950_client: fix NULL ptr reference that could occur if two clients
919 connected concurrently and if max-sockets was in effect.
923 Fix bug 3497 - Metaproxy unstable while stopping.
925 Fix bug 3495 - SEGV in SRU filter.
929 Filter multi throws diagnostic 'Present Out of Range' when
930 appropriate - rather than returning 0 records.
932 Filter virt_db: fix bad result reuse. Could happen if a result
933 was overriden and a backend did not supported named result sets.
937 Filter log: category access logs diagnostics even if searchStatus
938 or presentStatus is 'success'.
942 The SRU to Z39.50 filter does repeated Z39.50 present requests
943 to fetch all records. Needed when a Z39.50 server returns partial
944 results (due to message size limits).
948 Metaproxy now kills all child processes that are spawned by
949 modules (in case of fork, exec).
953 Debian package now installs /etc/metaproxy/metaproxy.xml which
954 includes all XML files /etc/metaproxy/filters-enabled .
955 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
959 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
960 development package to facilitate 3rd party Metaproxy modules.
962 --- 1.0.23 2010/01/04
964 Filter virt_db: Close backend filter session when Init rejected is received
965 from it (in which case it's not really closed yet). This will ensure we don't
966 run out of resources such as FDs in this case.
968 sru_z3950 filter: Accept any database (including those not listed).
970 --- 1.0.22 2009/12/03
972 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
973 later which means YAZ 3.0.47 or later.
975 --- 1.0.20 2009/11/19
977 For filter virt_db, the database is a glob pattern and the virtual
978 database sections are consulted in the order given.
980 --- 1.0.19 2009/07/08
982 For filter multi, the target (for routing) may be given as a glob-pattern.
984 More documentation for filters virt_db and multi.
986 Update schema to allow for no database in sru_z3950 filter.
988 --- 1.0.18 2009/06/30
990 Added limit filter to put sleep (penalty) for heavy use.
992 Filter frontend_net may be configured to limit the number of new connections
993 from same IP to some value (connect-max).
995 Fixed the load_balance filter.
997 --- 1.0.17 2009/06/16
999 Fix path for metaproxy executable for Debian init.d script.
1001 --- 1.0.16 2009/06/10
1003 SRU to Z39.50 filter honors x-username and x-password. If only
1004 x-username is given that translates to open authentication (Z39.50v2). If
1005 both x-username and x-password is present that translates to idPass
1006 authentication (Z39.50v3).
1008 New facility to change current working directory (-w).
1010 Update to upstream skeleton of init.d script. Should fix bug #2619.
1012 Filter session_shared now caches records (used to only cache connections
1015 Filter session_shared now invalidates a Z39.50 session if a server
1016 returns -1 hits. This facility was also part of yazproxy and gets around
1017 a bug in Voyager-based Z39.50 servers.
1019 --- 1.0.15 2008/11/18
1021 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1023 --- 1.0.14 2008/06/09
1025 Fixed the value of SRU record schema in searchRetrieve response. It was set
1026 to a fixed value of "dc" before.
1028 Serialize identical SRU requests. This is useful if HTTP client software
1029 fires identical requests against metaproxy.
1031 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1032 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1033 avoid static configuration. This facility is handled by the sru_z3950 module
1034 and the z3950_client module.
1036 Allow maximum number of sockets to be used for a Z39.50 client by the
1037 use of SRU extra parameter x-max-sockets. This facility is handled by the
1038 sru_z3950 module and the z3950_client module.
1040 --- 1.0.13.1 2008/02/29
1042 Simplified check for Boost libraries.
1044 --- 1.0.13 2008/02/29
1046 First Debian package.
1048 The sru_z9350 filter now recognizes SRU parameter z-target as being
1049 a ZURL of the form host/database .
1051 Mergetype may be specified for filter 'multi'.
1053 --- 1.0.12 2007/09/19
1055 Fixed problem in Makefile WRT library specifictions. This could produce
1056 linker errors (when they should not happen).
1058 Fixed bug #1341: MetaProxy returning different results. Problem was that
1059 fix-up of record database did not normalize the database name.
1061 Documentation updates for Windows compilation.
1063 --- 1.0.11 2007/06/14
1065 Fixed problem with logfile being truncated.
1067 --- 1.0.10 2007/05/23
1069 Fixed bug #1136: Access rights not enforced.
1071 Extension for log module. The log category 'access' logs more details.
1072 New category 'user-access' added which is simlar to 'access' but adds
1073 the Z39.50 user as for all entries in a session.
1077 Added support for configurable default/force target/vhost for module Z39.50
1080 --- 1.0.8 2007/01/25
1082 Implemented filter, session_shared, which optimizes usage of Z39.50
1083 sessions and result sets.
1085 New filter, record_transform, which converts MARC/XML records.
1087 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1089 New filter, load_balance, in development.
1091 New filter, zeerex_xplain.
1093 XML framework for config files started.
1095 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1096 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1097 XML config files are checked against RNG and XML Schema's.
1099 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1100 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1101 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1102 explain record to YAZ CQL-to-PQF text config file.
1104 --- 1.0.7 2006/11/07
1106 Added 'timeout' setting for filter frontend_net which specifies the number
1107 of seconds a session is idle before it is closed. Default timeout is
1110 --- 1.0.6 2006/07/07
1112 Database name in records returned set for virt_db/multi filters.
1114 Filter session_shared now functional.
1116 Log filter can be configured to write to a given file using 'filename'
1117 element. Also information category can be specified with 'category'. If
1118 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1121 --- 1.0.5 2006/05/16
1123 Fixed compilation on Windows.
1125 --- 1.0.4 2006/05/16
1127 Added documentation for the hidenavailable option for the multi filter.
1129 --- 1.0.3 2006/05/16
1131 Fixed bug #573: Hide errors for individual servers. If the element
1132 'hideunavailable' is given in the configuration, individual servers
1133 being unavailable are hidden (unless all are unavailable).
1135 Fixed bug #574: Database names are recognised case-sensitively.
1137 Fixed bug #567: Fix up database name in Name-Plus-Record.
1139 Fixed bug #568: Update win/makefile for VS 2005.
1141 Fixed bug #569: Some options throws unknown exception.
1143 --- 1.0.2 2006/04/28
1145 More information about virtual hosts. The 'etc' directory is part of the
1148 --- 1.0.1 2006/04/27
1150 Build instructions for Windows. NMake makefile part of distribution tar.
1152 --- 1.0.0 2006/04/24
1156 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1157 log, multi, query_rewrite, template, virt_db, z3950_client.
1159 Filters in development: session_shared.
1161 Pseudo-filters: template, dl
