3 http_file: add include of sys/stat.h fixes MP-576
5 Fix documentation about SRU client support MP-572
7 Initialize Libxml2 - for threaded operation MP-571
11 On SIGTERM shut down connection+listening sockets MP-568
12 This fixes a problem with 'metaproxy stop' sometimes taking a long time.
16 zoom: make retry on failure configurable MP-565
17 The default and existing behavior is that backend failures (any
18 diagnostic) makes the module re-search once. The behavior may
19 be changed by db parameter 'retry'. If given value '0' disables
20 retry and '1' enables it. If not given, the Torus record may
21 specify with element retryOnFailure (value '0'/'1').
25 Fix race condition in SIGTERM handling. Could terminate whole metaproxy
26 instead of just a child process. Extremely rare in real life, hit me with
27 CF stress testing. MP-559.
31 http_file: passthru option MP-557
32 New facility for http_file to passthru - even if an area is matched. The
33 default behavior (passthru=false) is to return 404: Not found. With
34 passthru=false, next filter is consulted.
38 Fix ref to freed memory in log filter 1line - MP-556
40 echoedSearchRetrieveRequest support MP-555
44 zoom: allow hostname to be given for ipauth MP-552
45 The Torus setting for that is called auth_hostname.
49 zoom: IP auth use field "ipRanges" rather than "ip" MP-551
53 session_shared: close in ~BackendInstance MP-549
54 This fixes a serious issue where some MP would leak sockets.
56 session_shared: mutex lock in BackendClass::release_backend MP-550
57 Fixes a SEGV that could occur (in rare cases).
61 zoom: Do not include ZOOM C's fake surrogate diag recs MP-547
63 zoom: fix invalid present response in some cases MP-546
65 zoom: Relay Torus HTTP error message
69 Check for proper limits before using RecordCache functions MP-544
73 Build packages for Ubuntu Trusty Tahr 14.04 LTS
75 sort: crash / invalid_read in filter sort MP-541
77 sru_z3950: facet should be stored in additionalSearchInfo MP-533
79 doc: fix missing man pages MP-542
81 cql_rpn: fix threading problem with CQL to RPN conversion MP-497
83 cql_rpn: allow conversion from RPN to CQL (reverse) MP-537
87 sru_z3950: fix facet response (memory corruption) MP-532
89 log: fix crash idPass user is omitted MP-530
93 query_rewrite: pass-thru non Type-1 queries MP-527
95 metaproxy stop (SIGTERM) kills all child processes spanwed by
96 filter (if any) before invoking filter destructors. MP-525
100 http_file: only supports HTTP GET MP-523
102 session_shared: shut down expire thread in destructor
103 This ensures that expire thread is not running after destruction
104 and does bad memory references, etc.
106 frontend_net: fix segfault on startup MP-524
107 Would happen if MP was listening on multiple ports and one
108 of the ports was already in use (and MP would exit).
110 frontend_net: fix memory leak MP-521
111 This leak would occur if all sessions were in use and the input
112 queue was cleared when a client would close connection (socket).
114 frontend_net: fix compilation on Windows (SIGUSR1 does not exist)
118 http_rewrite: use local skiplist; fixes memory corruption. MP-520
120 http_client: x-forwarded-for controls X-Forwarded-For presence
121 If x-forwarded-for setting (boolean) is enabled, http_client will
122 generate an X-Forwarded-For header entry which includes existing
123 X-Forwarded-For (if any) and current peer address (immediate client
124 of Metaproxy). By default x-forwarded-for disabled and X-Forwarded-For
125 will not be generated.
127 z3950_client: client_ip controls client-IP presence
128 If client_ip setting (boolean) is enabled, z3950_client will
129 generate a client_ip OID as part of init request which includes
130 previous client_ip (if any) and current peer address (immediate
131 client of Metaproxy). By default client_ip is disabled and client_ip
132 will not be generated.
134 HTTP X-Forwarded-For/Z39.50 Client-IP support
135 virt_db, multi: relays Z39.50 client-IP.
136 sru_z3950: converts X-Forwarded-For header to Z39.50 client-IP.
137 zoom: uses Client-IP or origin address (prefer Client-IP).
138 frontend_net: Strips tcp: from peer address (so that it is no longer
139 printed and stripped in zoom filter).
140 z3950_client: builds client-IP list - combining immediate peer address
141 as returned by COMSTACK and existing client-IP list (if avaiable).
142 The Origin only printes first X-Forwarded address.
146 Log when SIG{TERM,USR1} is received ASAP MP-513
147 Do it in frontend_net event loop rather than in place for metaproxy
148 main, which only exits when all sessions are terminated for SIGUSR1
151 metaproxy-config: quote some RHS values (that might include blanks)
153 Fix leak in sru_z3950 filter - when explain is returned MP-511
155 Allow stylesheet to be given for sru_z3950 filter MP-510
156 This is based on a patch by Sven Porst and the functionality
157 of the YAZ Generic Frontend Server.
159 Allow base attribute in configuration file tags - the attributes are
160 inserted by XInclude usage as mentioned on
161 yazlist: http://lists.indexdata.dk/pipermail/yazlist/2012-Au
162 and noted in a gist: https://gist.github.com/3551094
164 Package metaproxy provides virtual package metaproxy6 MP-508
165 This allows module packages to depend on a metaproxy server
168 Filter destructors called upon daemon termination MP-505
169 When metaproxy daemon receives SIGTERM the stop method of each filter
170 is called. The stop method existed before, but did not take any
171 arguements (void).. The frontend_net filter can now distinguish
172 between SIGUSR1 (stop bind, but keep sessions running) and SIGTERM
173 (stop immediately). Note that this changes the API+ABI of Metaproxy
176 zoom: sync up with Pazpar2 WRT authentication handling MP-492
178 Router: use shared_ptr rather than naked one - to avoid leak if an
179 exception is thrown in configure.
183 zoom: Add nocproxy=1 for contentConnector sessions MP-501
185 Doc: mention proper versions; fix link to Boost win binaries.
187 Windows: update for Boost 1.55
189 Windows: avoid warning when using boost::split. Done by defining
190 _SCL_SECURE_NO_WARNINGS for Visual Studio.
192 Fix LSB conformance for /etc/init.d/metaproxy MP-500
193 Debian: add support for /etc/init.d/metaproxy status
195 sort: Add const to Record less than operator in order to compile on
200 session_shared: fix element-set handling in record caching. MP-499
202 document http_rewrite. MP-468
204 http_write: Honor X-Metaproxy-SkipLink MP-479 . Filter understands and
205 respects the header (which will normally come from the cproxy filter)
209 RPM: fix dependency for libmetaproxy5-devel MP-496. The libmetaproxy5-devel
210 RPM was unsable in version 1.4.0.
212 Remove log message about "backend classes". Appeared in version 1.4.0.
216 Build RPM/Deb packages with YAZ 5 and yazpp 1.5. Metaproxy still compiles
217 with older version from source, but packages now use YAZ 5 that supports
220 sru_z3950: Fix SEGV for decoding invalid SRU requests
221 Incorrect reference to union (was explain response rather than
224 session_shared: match additionalSearchInfo (includes facets). In
225 layman's terms means that means that facets are properly handled
226 by this filter. Eg a change in requested facets will issue new
227 search and facets from exisiting result set are cached.
229 --- 1.3.62 2013/09/11
231 http_rewrite: better handling of <script> content in HTML parser. MP-486
233 http_rewrite: fix threading issue with regex. MP-482
235 bounce: don't use strdup for fixed length content. Error occurred in echo
238 session_shared: expire backend class when no instances left. This
239 means memory clean up, but not really a leak fix.
241 virt_db: fix leak for naked ptr.
243 cql_rpn: use config relative path for cql2rpn file. MP-481
245 Updates for upcoming YAZ 5.
247 --- 1.3.61 2013/08/29
249 New configuration directories ports.d/routes.d for metaproxy
250 configuration. This allows 3rd party packages to install config
251 for ports and new routes. MP-477
253 --- 1.3.60 2013/08/21
255 Fix metaproxy-config --libs to return non-mt over mt libs.
256 The -mt versions do not exist as shared objects and cause
257 linker errors for applications linking with Metaproxy.
258 Problem present in versions 1.3.56 - 1.3.59. MP-475
260 HTML: clean up char checks. Add ptr to HTML parse spec
262 HTML parser stops eating tag when <-char is met MP-473
264 rewrite: do not even compare content types, if we don't have any
265 the regex_match caused a segfault if we had no content-type in the
268 rewrite: within header=... matches only the header value
269 Used to match the whole header line, but we need to use
270 ^$ anchoring for host-relative regexps, and they need to
271 anchor at the ends of the value. MP-470.
273 rewrite: Ruleset functional MP-469
275 --- 1.3.59 2013/07/12
277 session_shared: negotiate init sz parameters.
278 By default, session_shared will honor the paramters given by client.
279 An alternative, but not implemented, algorithm would be to only
280 re-use sessions with same sz parameters. This however, could reduce
281 re-use of sessions a lot. Hence this, simple algorithm instead. The
282 negotiation to a maximum sz values can be enabled by using
283 <init maximum-record-size="sz1" preferred-message-size="sz2"/>
284 in configuration. This will make session_shared send those values
285 to backends and use returned init values in negotaition to
286 client before session_shared.
288 session_shared: resolve result-set references.
289 The reference is substitued with the query for old set if database
290 match and query type is Type-1. If not the reference will issue a
293 sort filter: relays RecordComposition including elementSet in use for
296 http_client: better diagnostics
298 http_client: disables HTTP redirect handling by default.
299 It can be configured with max-redirects in configuration.
301 --- 1.3.58 2013/06/12
303 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
305 --- 1.3.57 2013/06/12
307 Make RouterChain and RouterXML part of public API (libmetaproxy).
309 http_client: honor X-Metaproxy-Proxy as an alternative to
310 the "proxy" configuration. Allows proxy to be set per HTTP request.
312 sru_z3950: For SRU requests recognize x-client prefixes as a way
313 to ingest "database parameters".. The suffix of x-client- serves
314 as database argument name. Multiple may be given. For example:
315 http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
316 is turned into Z39.50 database
319 --- 1.3.56 2013/05/27
321 New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
323 New filter sd_remove, which replaces surrogate diagnostics with
324 SUTRS records. This filter tries to deal with clients that breaks
325 when receiving surrogate diagnostics.
327 new filter http_client. Same role as z3950_client, but just for
328 HTTP. Allows Metaproxy to operate as a HTTP proxy.
330 New filter http_rewrite1, which serves as purpose on how to rewrite
331 HTTP content with Metaproxy.
333 Use libboost-system if available, because newer versions of libboost-threads
334 requires libboost-system.
336 Allow frontend_net to serve SSL/HTTPS, because we can specify a server
339 --- 1.3.55 2013/04/10
341 zoom: Torus setting: authenticationMode which may hold values "basic"
344 --- 1.3.54 2013/03/27
346 configure: check for Libxslt support in YAZ and rely on definitions
347 from yaz-config, rather than doing own xslt/xml2 checks.
349 Allow timestamp format for log lines to be given with option -m
350 for metaproxy. Similar to yaz-ztest/GFS option -m.
352 Document log category 'line' for log filter.
354 Solr configuration example in etc/config-solr.xml
356 multi: do not mess with request package. For scan and search,
357 database-names were modified and the request package was left with
358 dangling pointers that caused a log filter to fail (request package
359 inspected after multi was invoked).
361 Documentation: fix id of metaproxy-config ref .
363 Documentation: update for USEMARCON support.
365 --- 1.3.53 2013/01/31
367 record_transform: allow OPACXML to OPAC conversion
369 zoom: document content-proxy
371 zoom: document db parm content-{user,password}, torus_url. Also
372 <torus auth_url="..> which makes zoom operate in authenticated mode
375 --- 1.3.52 2012/11/30
377 zoom: fix http://-check. SRU search broken in 1.3.51.
379 --- 1.3.51 2012/11/15
381 zoom: only append http:// for SRU if not already given . Makes it
382 possible to use https-URLs.
384 Use yazpp 1.4 or later due to new ABI.
386 frontend_net: allow max package size to be specified. Controlled by
387 attribute 'max_recv_bytes' of element 'port'.
389 --- 1.3.50 2012/10/29
391 For most generated diagnostics by filters, typically temporary
392 system error, augment addinfo message with filter name.
394 Add support for CentOS 6 packages.
396 sru_z3950: interpret Z39.50 diagnostics part of Init Response.
398 Add man page for metaproxy-config.
400 --- 1.3.49 2012/10/18
402 zoom: new config element passthru. This defines an element set that is
403 passed verbatim to the backend in pz2 mode.
405 auth_simple: allow both idPass and open auth. Also fix SEGV that could
408 --- 1.3.48 2012/10/08
410 z3950_client: fix string handling for init diagnostics in the case where
413 query_rewrite: no charset conversion for error queries. Avoid performing
414 charset conversion for query conversion errors. The resulting Type-1
415 query is invalid in this case.
417 --- 1.3.47 2012/10/04
419 For graceful stop (SIGUSR1), metaproxy will kill children processes.
421 Log when metaproxy is invoked in test mode (-t).
423 Log PID for each log message.
425 multi: combine both NSDs and multiple NSDs into one (diagnostics).
427 z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
428 a (backend=target) is appended for each diagnostic so that can be
429 determined the origin of error.
431 multi: hideerrors also in use for present response.
433 Solr example in zoom man page.
435 Fix typo in query_rewrite config example.
437 Log at least first non surrogate diagnostic. Instead of
438 "Z_Records_multipleNSD"
440 multi: Fix check for opt Records in present response. A SEGV could occur
441 if a target did not return records and no diagnostics.
443 --- 1.3.46 2012/09/24
445 Yet another fix for graceful stop.
447 --- 1.3.45 2012/09/12
449 sru_z3950: relay surrogate diagnostics.
451 --- 1.3.44 2012/09/10
453 zoom: Honor extraArgs, strip # in zurl.
455 multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
457 zoom: url_recipe allow %{var[reg]} substitutions.
458 It's like ${var[reg]} but does URI component encoding as well.
460 --- 1.3.43 2012/08/22
462 RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
463 non-keepalive HTTP sessions.
465 http_file: allow zero size files (bug fix)
467 Fix zoom schema: auth_url is optional
469 --- 1.3.42 2012/08/20
471 zoom: fix un-init memory (could result in SEGV at session close)
473 frontend_net: handle X-Forwarded-For. This is stored in package.origin()
474 and may be used in filters as usual.
476 zoom: authentication via Torus lookup
477 Enabled by new configuration setting: auth_url . If this is defined,
478 the zoom module will contact Torus for auth/IP lookup and that will
479 define realm to be used in session.
481 --- 1.3.41 2012/08/10
483 virt_db: Fix database name - first character we removed by mistake.
484 Bug introduced in 1.3.40.
486 --- 1.3.40 2012/08/06
488 virt_db: Don't use "unix path" as database for Unix sockets.
490 --- 1.3.39 2012/08/02
492 z3950_client: Don't tamper with / in zurl - fixes problems
493 using Unix sockets for backends.
495 session_shared: fix integer overflow problem with hit count.
497 session_shared: avoid long usage of cached queries.
499 zoom: New database argument , torus_url to set URL of Torus
500 record to be fetched.
502 --- 1.3.38 2012/07/04
504 Fixes for 'metaproxy reload' for RPM/Debian packages.
506 zoom: Allow rpn2cql conversion to be augmented with a properties file.
507 Element rpn2cql can be specified per-target for the zoom filter.
509 log: New category "line" which is a single-line log message with
510 most important parts of a HTTP/Z39.50 request/response.
512 --- 1.3.37 2012/06/01
514 frontend_net: add facility to report live statistics about response
515 times and current thread usage. The report is an XML document
516 and is triggered for a specific URL path. This is set by <stat-req>
517 in the configuration of frontend_net. By default this report is
518 disabled (same as empty value for <stat-req>).
520 Fix reload problem in init.d script for RPM/Debian.
521 The '/etc/init.d/metaproxy reload' in some cases would stop but not
522 start metaproxy - effectively stopping the service.
524 Don't display start log message when config testing (-t).
526 zoom: avoid CCL message limit of 1K in ZOOM filter.
528 --- 1.3.36 2012/05/10
530 metaproxy init script reacts to reload which does graceful stop +
531 start and is used by logrorate script.
533 --- 1.3.35 2012/05/09
535 Fixes for Windows compilation.
537 Metaproxy daemon reacts to SIGUSR1 in which case it will leave
538 existing sessions running but terminate the monitor process that is
539 used in keepalive mode.
541 Change start log message to 'metaproxy start'. Was 'Metaproxy start'
542 before. Consistent with 'metaproxy stop' message.
544 zoom: document zoom's proxy_timeout
546 z3950_client: fixup addinfo for init response
548 virt_db: return other diagnostic if init is rejected. Diagnostic 236:
549 "Access to specified database denied" is returned, but only if init
550 response from backend does not carry diagnostics already.
552 multi: relays user info for first rejected target. The other-information
553 field for init response for first rejected target is in common init
554 response. This ensures that some backend init diagnostics are returned to
557 --- 1.3.34 2012/04/25
559 frontend_log: extend logging (when message is given in config).
561 --- 1.3.33 2012/04/25
563 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
565 --- 1.3.32 2012/04/24
567 sru_z3950 filter passes through incoming Z39.50 requests again. Was
568 not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
570 --- 1.3.31 2012/04/24
572 zoom: fixes for retry/proxy failover logic. More logging.
574 --- 1.3.30 2012/04/23
576 zoom: return addinfo="proxy failure" for proxy failures. This also
577 changes the scheme for dealing with proxies a bit. zoom now always
578 do proxy check, even if there's no failover. Fortunately, that's not
581 zoom: Init rejected wo diagnostics maps to Bib-1:1014.
582 Bib-1 1014, "Init/AC: Authentication System error", seems pretty
583 generic. We don't know why the init would fail; IP, user, block IP, etc.
584 sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
586 zoom: guess if invalid SRU response was an auth failure
588 session_shared: disable session retry by default . Can be enabled by
589 restart="true" in resultset section.
591 --- 1.3.29 2012/04/18
593 zoom: may read cf-proxy's config settings.
594 This reduces manual configuration of the content proxy server host.
595 The ZOOM module will use the old style session.proxyhost if "server"
596 is given (deprecated) and use the new style proxyhost/session if
597 "config_file" is in use.
599 frontend_net: remove incoming requests that can not be handled
600 Requests in queue for filter frontend_net are removed if client
601 closes connection for the session and request is not yet handled.
603 sru_z3950: serialize requests. This is to ensure that pipelined
604 HTTP requests are handled properly.
606 --- 1.3.28 2012/04/04
608 New class, wrbuf, that wraps YAZ' WRBUF.
610 --- 1.3.27 2012/03/30
612 Metaproxy daemon is now running as user "metaproxy". This user is
613 managed by package maintainer scripts. The user information is stored
614 in /etc/metaproxy/metaproxy.user .
616 --- 1.3.26 2012/03/20
618 New filter, sort, that allows sorting of XML records via Z39.50
621 Filter record_transform: USEMarcon support. For example:
622 <retrieval syntax="usmarc">
623 <backend syntax="unimarc" name="F">
624 <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
628 Filter multi: empty route pattern uses route as default.
630 <target route="z3950.indexdata.com">z3950.indexdata.com</route>
631 may use the shorter notation
632 <target route="z3950.indexdata.com"/>
634 Filter query_rewrite: use config path to locate XSLT.
636 Filter frontend_net: log statistics.
637 If a custom message element in frontend_net configuration it makes
638 the frontend_net filter produce a log entry whenever an operation
639 is completed. The log is always written using yaz_log with the
640 custom message given, the package ID (session ID) , the time
641 the operation has been active (end-to-end) , the threads currently
642 active/total and the size of the request input/output queues.
644 query_rewrite: charset conversion of query terms.
645 This is an optional feature. Enabled by element <charset> in
646 configuration with attribute 'from' and 'to' that specifies
647 from/to encodings. The default 'from' encoding is UTF-8.
649 Filter record_transform: honor piggyback searches.
651 Filter zoom: re-connect when database is reused.
652 Re-connect is necessary if a connection is lost or a timeout occurs.
653 If not, we'll be seeing zero hits, when we shouldn't.
655 --- 1.3.25 2012/02/29
657 zoom: Change scheme for dealing with content proxy URLs. The module
658 now has its own common XSL transform that is enabled by record_xsl
659 attribute in the configuration. This XSL gets parameter cproxyhost
660 that holds the host for the content proxy session . The genearted-url
661 is created only if urlRecipe is enabled. In previous version default
662 value of urlRecipe was ${md-electronic-url}; it is now empty and
663 disabled by default. Also generated-url no longer includes the content
664 proxy host. Content proxying URLs is supposed to the handle in the record_xsl
667 zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
668 connections. Default value is 40 (seconds).
670 zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
671 "Malformed query" for syntax errors and related ones; throw
672 Bib-1: 3 "Unsupported search" for everything else. Details from
673 the CCL parser is provided as additional-info.
675 multi: new setting hideerrors that makes multi only relay diagnostics
676 to a client if all backends fail.
678 --- 1.3.24 2012/02/23
680 zoom: empty ccl_map field-mappings disables CCL map.
682 zoom: fix Explain search that could return error if session was
685 --- 1.3.23 2012/02/10
687 zoom: returns Explain records for database IR-Explain---1. The
688 target profile records are converted to Explain records via XSLT.
690 session_shared: make error recovery configurable. Whether a search
691 is restarted on errors or not, is configurable by attribute "restart"
692 in element "resultset" in configuration.
694 session_shared: only relay init for first request. session_shared, for
695 each backend class, now only relays first init request (rather than all).
696 The module only needs to save init response info once. This avoids the
697 need to check for session max.
699 --- 1.3.22 2012/02/02
701 zoom: fix memory leaks.
703 session_shared: maximum number of sessons is configurable. Default
704 value is 100. Result-sets for backends without named result sets are
705 only re-used if databases is identical for a search. This is under the
706 assumption that performance may suffer for those backends when
707 changing the database for each search.
709 multi: combines diagnostics from all backends. All diagnostics from
710 backends are combined into multiple non-surrogate diagnostics; rather
711 than just one diagnostic from first backend.
713 --- 1.3.21 2011/12/27
715 zoom: relay realm to cproxy parameter file.
717 Configuration: Allow filter collection element inside route. This
718 makes it possible to include multiple filters at once.
720 zoom: nocproxy also disables urlRecipe.
722 --- 1.3.20 2011/12/21
724 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
725 "Illegal sort relation" is returned. Gets translated to SRU diagnostic
726 90: "Unsupported direction value".
728 zoom: honor database argument nocproxy. This disables creating a content
729 connector session (for non-CF targets, usually) and also relays nocproxy
730 as database argument to a CF target.
732 --- 1.3.19 2011/12/16
734 zoom: Multiple proxy hosts may be given for proxy rich database
735 parameter. List is comma separated.
737 http_file: decodes URI paths properly. Does not return 404: not found
738 if no prefix are matches. Instead packages are passed on.
740 --- 1.3.18 2011/12/08
742 zoom: content-{user,password,proxy} are passed on to content proxy
743 system and takes precedence over user,password,proxy .
745 sru_z3950: SRU extra argument x-log-enable=1 enables a search response
746 with a log element including log material from children filters. At
747 this point, only the zoom filter uses this log facility. It will
748 eventually be used by other filters as well. In particular it might be
749 useful for this feature to track all filters in used during a search.
751 zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
752 and queries as they are manipulated are logged.
754 zoom: extend addinfo with native diagnostics. Diagnostics as received
755 by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
756 diagnostics. This indicates both a backend diagnostic and the original
759 zoom: default urlRecipe value is ${md-electronic-url}
761 zoom: target profile setting sruVersion is recognized.
763 --- 1.3.17 2011/11/17
765 zoom: log target profile record fetched (AKA Torus).
767 --- 1.3.16 2011/11/17
769 Change target profile parameter CfSubDb to CfSubDB.
771 --- 1.3.15 2011/11/12
773 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
774 makes sense to the zoom module itself).
776 --- 1.3.14 2011/11/11
778 zoom: realm may be given as part of database.
780 --- 1.3.13 2011/10/26
782 Fix Origin class assigment method; was removd by mistake in 1.3.12.
784 --- 1.3.12 2011/10/26
786 zoom: database args x-name=value are passed through to backend database.
788 SRU filter: user may specify session ID that is passed to log entries
789 that follows. It is specified by using x-session-id in the SRU arguments.
791 zoom: fix null pointer reference which would occur for bad url parameter
792 inside "torus" or if url was not given.
794 --- 1.3.11 2011/09/09
795 Fix bug in filter session_shared where sessions would not expire
796 properly (session ttl). This in turn could make the target close the
797 connection before expected and session_shared would return diagnostic
798 2: system temporarily available.
800 --- 1.3.10 2011/09/09
802 zoom: new target profile setting: sortmap_field. If sortmap_field is given
803 the field is mapped to the value for the sortmap. Values not matching
804 sortmap_field are passed verbatim.
806 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
807 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
808 depending on whether RPN or CQL is actually sent to the target.
812 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
814 zoom: For content proxy authentication is stored in param name
815 "auth", instead of "authentication".
819 zoom: relay schema in SRU mode. Previously recordSchema was not affected
824 zoom: new target profile element literalTransform that holds XSLT
825 (encoded as string) for target. Only if present and non-zero length it is
826 considered present. This takes precedence over transform.
828 Don't rely on trang anymore for Git checkout builds. Configuration in etc
829 will only be properly validated if trang is available. From now on only
830 relax NC files are bundled with the source dist.
832 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
833 component was not detected when it should be.
837 z3950_client: mark non-surrogate diagnostics from backend.
839 zoom: a proxy may be specified for HTTP fetch of target profiles.
843 Honor piggyback. Makes some SRU targets behave that insist on
844 maximumRecords > 0, but also increases performance.
848 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
849 file was not update for libdir/metaproxy4 in version 1.3.2.
853 Change location of Metaproxy modules from libdir/metaproxy to
854 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
855 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
857 New facility to dump APDUs from zoom filter. Enabled by
858 <log apdu="true"/> in the zoom filter configuation.
860 zoom filter bug fix: SRU diagnostics received from backend was
861 not properly converted to Bib-1 diagnostics.
863 Package metaproxy depends on libmetaproxy4, same version.
867 zoom: fix a bug WRT passing authentication parameters to backends.
871 Fixes for windows Makefile.
873 --- 1.2.10 2011/07/25
875 Change major version of metaproxy library from 3 to 4. This in turn
876 makes new package names for Debian and RPM.
880 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
883 zoom: configurable element sets for record transforms.
885 zoom: the target profile based transform is specified by element_transform
886 in element torus of of the ZOOM filter configuration ; default value
887 is "pz2". Target profile based retrieval is specified by element_raw
888 in configuration. It will perform same steps, but omit the XSL transform.
889 Default value is "raw".
891 zoom: element set is omitted if not set in profile. But only if pz2
892 transform is in effect. Previously the default element set was to "F".
894 zoom: For non-CF targets database arguments are parsed. User may supply
895 db,user=myuser&password=mypass for non-CF targets. These values override
896 what's given the authentication from the target profile.
898 session_shared: fix reference to freed memory. Would occur if a search
899 response had non-surrogate diagnostics.
903 Route may be given for each port in frontend_net.
907 Documentation for zoom filter. Local target profiles may be specified.
909 Fixes for zoom filter.
913 First version with zoom filter.
917 Filter z3950_client may be configured to always send a close APDU
918 to backend target when connection/session is closed. This will only
919 happen if close APDU is not already sent. Enabled by configuration
920 for z3950_client (force_close).
922 Filter virt_db and multi: relay close APDU.
924 Filter virt_db and multi: relay init size parameters
925 preferredMessageSize and maximumRecordSize.
927 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
931 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
933 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
934 as determined by configure.
936 RPM: Release includes 'indexdata' name. Use indexdata in release name so
937 this package can be distinguished from other vendors.
941 Fix filter multi: relay idAuthentication parameters.
945 Add metaproxy-config for returning compiler flags, libraries.
949 Fix --with-boost=PREFIX .
953 session_shared: fix use of maintenance thread.
955 Introduce 'start' method for filters and routers. It gets called after
956 configure and after fork, but before processing. This changes API -
957 from libmetaproxy2 to libmetaproxy3.
961 session_shared: ensure backend session is closed if init rejected
964 z3950_client: fix NULL ptr reference that could occur if two clients
965 connected concurrently and if max-sockets was in effect.
969 Fix bug 3497 - Metaproxy unstable while stopping.
971 Fix bug 3495 - SEGV in SRU filter.
975 Filter multi throws diagnostic 'Present Out of Range' when
976 appropriate - rather than returning 0 records.
978 Filter virt_db: fix bad result reuse. Could happen if a result
979 was overriden and a backend did not supported named result sets.
983 Filter log: category access logs diagnostics even if searchStatus
984 or presentStatus is 'success'.
988 The SRU to Z39.50 filter does repeated Z39.50 present requests
989 to fetch all records. Needed when a Z39.50 server returns partial
990 results (due to message size limits).
994 Metaproxy now kills all child processes that are spawned by
995 modules (in case of fork, exec).
999 Debian package now installs /etc/metaproxy/metaproxy.xml which
1000 includes all XML files /etc/metaproxy/filters-enabled .
1001 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
1003 --- 1.1.0 2010/01/20
1005 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
1006 development package to facilitate 3rd party Metaproxy modules.
1008 --- 1.0.23 2010/01/04
1010 Filter virt_db: Close backend filter session when Init rejected is received
1011 from it (in which case it's not really closed yet). This will ensure we don't
1012 run out of resources such as FDs in this case.
1014 sru_z3950 filter: Accept any database (including those not listed).
1016 --- 1.0.22 2009/12/03
1018 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
1019 later which means YAZ 3.0.47 or later.
1021 --- 1.0.20 2009/11/19
1023 For filter virt_db, the database is a glob pattern and the virtual
1024 database sections are consulted in the order given.
1026 --- 1.0.19 2009/07/08
1028 For filter multi, the target (for routing) may be given as a glob-pattern.
1030 More documentation for filters virt_db and multi.
1032 Update schema to allow for no database in sru_z3950 filter.
1034 --- 1.0.18 2009/06/30
1036 Added limit filter to put sleep (penalty) for heavy use.
1038 Filter frontend_net may be configured to limit the number of new connections
1039 from same IP to some value (connect-max).
1041 Fixed the load_balance filter.
1043 --- 1.0.17 2009/06/16
1045 Fix path for metaproxy executable for Debian init.d script.
1047 --- 1.0.16 2009/06/10
1049 SRU to Z39.50 filter honors x-username and x-password. If only
1050 x-username is given that translates to open authentication (Z39.50v2). If
1051 both x-username and x-password is present that translates to idPass
1052 authentication (Z39.50v3).
1054 New facility to change current working directory (-w).
1056 Update to upstream skeleton of init.d script. Should fix bug #2619.
1058 Filter session_shared now caches records (used to only cache connections
1061 Filter session_shared now invalidates a Z39.50 session if a server
1062 returns -1 hits. This facility was also part of yazproxy and gets around
1063 a bug in Voyager-based Z39.50 servers.
1065 --- 1.0.15 2008/11/18
1067 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
1069 --- 1.0.14 2008/06/09
1071 Fixed the value of SRU record schema in searchRetrieve response. It was set
1072 to a fixed value of "dc" before.
1074 Serialize identical SRU requests. This is useful if HTTP client software
1075 fires identical requests against metaproxy.
1077 Allow Z39.50 target to be specified for SRU requests by using SRU extra
1078 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
1079 avoid static configuration. This facility is handled by the sru_z3950 module
1080 and the z3950_client module.
1082 Allow maximum number of sockets to be used for a Z39.50 client by the
1083 use of SRU extra parameter x-max-sockets. This facility is handled by the
1084 sru_z3950 module and the z3950_client module.
1086 --- 1.0.13.1 2008/02/29
1088 Simplified check for Boost libraries.
1090 --- 1.0.13 2008/02/29
1092 First Debian package.
1094 The sru_z9350 filter now recognizes SRU parameter z-target as being
1095 a ZURL of the form host/database .
1097 Mergetype may be specified for filter 'multi'.
1099 --- 1.0.12 2007/09/19
1101 Fixed problem in Makefile WRT library specifictions. This could produce
1102 linker errors (when they should not happen).
1104 Fixed bug #1341: MetaProxy returning different results. Problem was that
1105 fix-up of record database did not normalize the database name.
1107 Documentation updates for Windows compilation.
1109 --- 1.0.11 2007/06/14
1111 Fixed problem with logfile being truncated.
1113 --- 1.0.10 2007/05/23
1115 Fixed bug #1136: Access rights not enforced.
1117 Extension for log module. The log category 'access' logs more details.
1118 New category 'user-access' added which is simlar to 'access' but adds
1119 the Z39.50 user as for all entries in a session.
1123 Added support for configurable default/force target/vhost for module Z39.50
1126 --- 1.0.8 2007/01/25
1128 Implemented filter, session_shared, which optimizes usage of Z39.50
1129 sessions and result sets.
1131 New filter, record_transform, which converts MARC/XML records.
1133 New filter, sru_z3950, which converts SRU to Z39.50 packages.
1135 New filter, load_balance, in development.
1137 New filter, zeerex_xplain.
1139 XML framework for config files started.
1141 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
1142 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
1143 XML config files are checked against RNG and XML Schema's.
1145 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
1146 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
1147 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
1148 explain record to YAZ CQL-to-PQF text config file.
1150 --- 1.0.7 2006/11/07
1152 Added 'timeout' setting for filter frontend_net which specifies the number
1153 of seconds a session is idle before it is closed. Default timeout is
1156 --- 1.0.6 2006/07/07
1158 Database name in records returned set for virt_db/multi filters.
1160 Filter session_shared now functional.
1162 Log filter can be configured to write to a given file using 'filename'
1163 element. Also information category can be specified with 'category'. If
1164 filename is omitted, the log filter writes to stdout. See etc/config5.xml
1167 --- 1.0.5 2006/05/16
1169 Fixed compilation on Windows.
1171 --- 1.0.4 2006/05/16
1173 Added documentation for the hidenavailable option for the multi filter.
1175 --- 1.0.3 2006/05/16
1177 Fixed bug #573: Hide errors for individual servers. If the element
1178 'hideunavailable' is given in the configuration, individual servers
1179 being unavailable are hidden (unless all are unavailable).
1181 Fixed bug #574: Database names are recognised case-sensitively.
1183 Fixed bug #567: Fix up database name in Name-Plus-Record.
1185 Fixed bug #568: Update win/makefile for VS 2005.
1187 Fixed bug #569: Some options throws unknown exception.
1189 --- 1.0.2 2006/04/28
1191 More information about virtual hosts. The 'etc' directory is part of the
1194 --- 1.0.1 2006/04/27
1196 Build instructions for Windows. NMake makefile part of distribution tar.
1198 --- 1.0.0 2006/04/24
1202 Filters functional: auth_simple, backend_test, frontend_net, http_file,
1203 log, multi, query_rewrite, template, virt_db, z3950_client.
1205 Filters in development: session_shared.
1207 Pseudo-filters: template, dl
