set.

request which has initiated the job creation. Actually the HTTP request is
generated as before, and then, if a job is created, it is set to the ID of the
HTTP request. This modification aims to greatly help the log analysis.

ID set by the TAP library was replaced by the one of the TAP library. The
consequence was a possible bad logging and since the ID is a timestamp, the
ID of the request was indicating a time posterior to a job creation.

when the content-type was not exactly 'application/x-www-form-urlencoded'
for normal POST requests, no parameter was read by the UWS/TAP library.
This content-type test has now been modified from a strict equality to a
startsWith test.
(Note: This bug only concerned the form encoded requests,
not the multipart ones)

[UWS] Fix bug in UWSServlet: the destroyJob action in POST must be tested before the setJobParam action....otherwise the setJobParam action is always applied which leads to a Forbidden error when trying to destroy a job.

[UWS,TAP] Add the origin of the main exception after the exception class name in the log entries. This origin includes the class, the method, the file and the line where the exception has been thrown.

[UWS,TAP] Fix regression: the log message for the event REQUEST_RECEIVED was not displayed any more.

[UWS,TAP] Errors and log management improvements. Particularly, now TAP and UWS are able to manage correctly HTTP request abortions (i.e. when the user stop the request before the response has been fully sent, or when there is a connection problem or a time-out). Such abortions are considered by UWS and TAP merely as job abortion/cancel. No error is logged any more. In addition of this correction, log entries concerning the execution of a TAP sync/async job have been modified so that having more coherents messages. And stack traces of exception that occurred when executing a job (sync or async, tap or uws) are displayed just once: at the JOB END log entry, and not by the HTTP RESPONSE_SENT entry. And finally, output flush and interruption detection are made more often when writing a query result (the flush is particularly important when combining with fetch-size > 0 in synchronous mode....the sync response is then a streaming output).

[UWS,TAP] Change the default log and backup files name. Before it was 'uws.*', but since the same FileManager is used for both services, this default name has been replaced by 'service.*'.

[UWS] Add a log message filter: only messages whose the level is greater or equal to a given one are displayed. This level is by default DEBUG (meaning all messages are always written).

[UWS,TAP] Set the user who submits the request in an HttpServletRequest attribute. Thus, every TAP and UWS resources can get it without extracting the information every time from the HttpServletRequest.

[UWS,TAP] Fix UPLOAD bug (the last line of the table to upload was ignored). Fix an improbable NullPointerException in the MultipartParser.

[UWS,TAP] Add clean release of all resources (e.g. Threads, Timers, DB connections) allocated in a UWS and a TAP service. Small changes of the UWS API...but only if ExecutionManager, DestructionManager and UWS have been implemented by library users rather than using the default implementation.

[UWS,TAP] Review some log messages (in the log file but also in the error summary of a job) ; particularly stack traces are added into the error summary, but are displayed just once in the logs.

[TAP,UWS] Addition to the last commit: the TAP resource /sync did not yet use the RequestParser to get its parameters, and so it did not worked as before the last commit.

[UWS,TAP] 3 MAJOR DEPENDENT FIX: improve significantly the parameters extraction from HTTP request in UWS (1) AND move the file-upload ability into the UWS library (2) AND the modification of parameters in UWS is now conform with the standard (3). (1) Only application/x-form-urlencoded content-type was supported. However a UWS must accept a request body containing only an XML document as a single byReference parameter. It is now done when the content-type is not known. (2) Besides multipart/form-data is now fully supported in UWS and so is still possible in TAP. (3) In the UWS standard, parameters can not be added after creation: they can just be modified. This rule is now respected in the UWS library.

[UWS,TAP] Review the standard parameters checking. Particularly, because before, the default value was never used while no value was specified by the user.

[ADQL,TAP] Add STC-S and UDFs support in the ADQL parser. Now, it is possible to provide a list of allowed UDFs, regions and coordinate systems. The ServiceConnection of TAP is now able to provide these lists and to propagate them to the ADQLExecutor. UDFs and allowed regions are now listed automatically in the /capabilities resource of TAP. The type 'geometry' is now fully supported in ADQL. That's why the new function 'isGeometry()' has been added to all ADQLOperand extensions. Now the DBChecker is also able to check roughly types of columns and UDFs (unknown when parsing syntactically a query). The syntax of STC-S regions (expressed in the REGION function) are now checked by DBChecker. However, for the moment, geometries are not serialized in STC-S in the output....but it should be possible in some way in the next commit(s).

[UWS] Correct the way the URL interpreter is used: at initilization with a HttpServletRequest, the full URL until the base URI should be saved + In UWSService, the used URL interpreter was a class attribute, which is a bad thing (this object is shared by several threads).

[UWS,TAP] Fix timestamp format. Now, each returned date will expressed in UTC and using the ISO8601 format. Any given date is also expected in UTC (or with a time zone offset) and in ISO8601Format. These rules apply also for uploaded tables and for timestamp columns in a query result.

[TAP,UWS] Fix a problem with the format of the error details returned by the parameter .../error/details. In TAP a VOTable document is expected, but a text/plain description was returned (default behavior in the UWS lib.). Now, a ServiceErrorWriter is used to format the error details correctly.

[UWS,TAP] Fix bug about UPLOAD: file upload (multipart/form-data) with a POST to the SetJobParam action was not possible & bug in the COS library about line termintation (it should be CRLF but some clients end lines with LF and that should have been managed by the COS lib but wasn't ; correction applied by myself but feedback from the lib developer is waited).

[UWS,TAP] Review the exceptions and logs management + Add log file rotation (with a configurable rotation frequency)

Remove useless and blocking test (when url-pattern in web.xml is set to the root: /*) in the UWS URL parsing. + Add very basic check on its implementation
