types. The notion of "unknown type" is different in function of the target
object:
  - a DBType and a FunctionDef have an unknown type if their function
    isUnknown() returns true. In such case, the other functions such as
	isNumeric/String/Geometry() will return false.
  - an ADQLOperand (e.g. ADQLColumn) does NOT have a isUnknown() function.
    But if the type of the operand is unknown, its functions isNumeric(),
	isString() and isGeometry() must ALL return true. Otherwise, just one of
	these functions can return true.

(merge with branch 'unknownFctType')

Such value is replaced by NULL while ingesting it into a Postgres
database.

[TAP] Small fix: the translated SQL query was logged only after the query execution ; so, in case of error,
the SQL query is not logged and can not be checked by service provider.

[TAP] Fix NullPointerException in TAPConfiguration (this error happens only when a NoSuchMethodException occurs.

[TAP] Add Javadoc for all TAP configuration file related classes + Improve the function ConfigurableServiceConnection.getFile(...) + Set the default value of limits/durations/periods to the maximum value if the new maximum value is less than the current default value.

[TAP] Incorrect setting of the backup frequency. The documentation was also incomplete about this property, but also wrong concerning the property backup_mode which is actually backup_by_user.

[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.

[TAP] Fix unterminated thread after a failed UPLOAD. This bug happened when an uploaded VOTable reading was interrupted by an exception (like a ParseException)....the streaming thread was not stopped and was still waiting for a notification in order to read the next row.

[TAP] Improve the default TAP service home page. Particularly, a form with a few basic javascript has been added.

[TAP] Correction of the default value for the upload_enabled property. By default, the UPLOAD feature is disabled.

[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).

[TAP] Change the internal column separator in the Text (human readable table) output. This separator has been choosen for the weak probability to be used in column values and so that avoiding confusion between a column separator and part of a column value. The column separator in the output/display stays the |.

[TAP] Add the possibility to set the FetchSize on a DB Statement for the execution of ADQL queries. It is also possible to set a fetchSize different for synchronous and asynchronous queries.

[TAP] Add a configuration file property: 'coordinate_systems'. It lets list all allowed coordinate systems. By default, the list is empty, meaning that any is allowed.

[TAP] Automatic research of the TAP configuration file is done only in the classpath, in WEB-INF and in META-INF. The rest is the Web Application directory is ignored, for security considerations (i.e. otherwise, the library would allow TAP administrators to make the configuration file public....only WEB-INF and META-INF are not public).

[TAP] Rename the property 'output_add_formats' into 'output_formats' & Correct the name of the service description in tap_full.properties.

[TAP] Default TAPSchema DB name set to the ADQL name ; so if the column TAP_SCHEMA.schemas.dbname is NULL or empty, the DB name must be set to the ADQL name. For the moment no empty schema is allowed.

[TAP] Change the default value for output and upload limits ; only negative value must mean 'no restriction' ; 0 must be a normal allowed value.

[TAP] Allow the TAP configuration file properties 'file_root_path' and 'metadata_file' be file pathes relative to WebContent.

[TAP] Qualify by default the standard TAP schema tables in TAP_SCHEMA.tables & Correct the primary key in TAP_SCHEMA.tables (it must be only 'table_name' and not 'schema_name, table_name').

[ALL] Update ANT build scripts to test all existings JUnit tests before compiling. In case of error, the compilation does not complete.

[TAP] Allow creation of PENDING jobs ONLY FROM the TAPFactory when the service is unavailable. Before this modification, the backup manager could not restore jobs at the service starting. When the service is said unavailable, the resources /sync and /async are rejecting HTTP requests, but jobs can be created and started in background (very useful for backup restoration but also for queued jobs).

[TAP] Add a property in the configuration file to set a custom TAPFactory (in replacement of ConfigurableTAPFactory.

[TAP] Add a 3rd possibility to set metadata in the TAP configuration file: give an extension of TAPMetadata having either an empty constructor or a constructor with a UWSFileManager, a TAPFactory and a TAPLog. & Rename function TAPConfiguration.isClassPath(String) into TAPConfiguration.isClassName(String).
