2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
	  Use BigDecimals as representation for the numeric components
	  which prevents running into unique constraint problems
	  caused by imprecision.

	* src/main/java/de/intevation/flys/importer/ImportRange.java,
	  src/main/java/de/intevation/flys/importer/ImporterSession.java:
	  Ranges are now cached globally, too.

	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java:
	  Improved logging.

	* src/main/java/de/intevation/flys/importer/ImportDischargeTableValue.java:
	  Removed superfluous imports.

2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/StaFileParser.java:
	  Only accept main value types 'Q', 'W', 'D' and 'T' by default.
	  '-' is not handled any more because it causes too much constraint
	  problems. You can overwrite the imported type with the
	  system property flys.backend.main.value.types" (default "QWTD")
	  
	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
	  Set session flush mode to manual. Hopefully this improves the
	  performance a bit.

	* src/main/java/de/intevation/flys/importer/ImportWst.java,
	  src/main/java/de/intevation/flys/importer/ImportGauge.java,
	  src/main/java/de/intevation/flys/importer/ImportWstColumn.java,
	  src/main/java/de/intevation/flys/importer/ImportRange.java,
	  src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
	  Improved logging.

2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/WstColumnValueKey.java: Deleted
	* src/main/java/de/intevation/flys/importer/IdValueKey.java: Reinserted
	  here in a more generalized form.

	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
	  Cache the discharge table value, too.

	* src/main/java/de/intevation/flys/importer/ImportDischargeTableValue.java:
	  Use the global cache.

2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
	  New. Centralized caching in the thread local context. Importing
	  the Elbe leads to OOM because the column values of the
	  WST files where loaded separately for every file.

	* src/main/java/de/intevation/flys/importer/ImportPosition.java,
	  src/main/java/de/intevation/flys/importer/Importer.java,
	  src/main/java/de/intevation/flys/importer/ImportAnnotation.java,

	  src/main/java/de/intevation/flys/importer/ImportAttribute.java,
	  src/main/java/de/intevation/flys/importer/ImportTimeInterval.java:
	  Adjusted to use the new global context.

2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* doc/schema/postgresql.sql: Dropped constraint which
	  forces discharge tables to have a unique time interval
	  for a given gauge and kind.

	  There are AT files (historical Mosel/Perl/Perl/1967-1981.at
	  and Mosel/Perl/1967-1981-1.at) which violate this
	  constraint. Its a technical question to the customer
	  how to handle these cases.

	  To adjust existing databases:

	    ALTER TABLE discharge_tables DROP CONSTRAINT discharge_tables_gauge_id_key;

2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/WstParser.java:
	  There are wst files where column names are not unique.
	  Make them unique by appending (1), (2) and so on.

2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/ImportRiver.java:
	  Import the "HW-Schutzanlagen", too.

2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	Make import of historical discharge tables work.

	* doc/schema/postgresql.sql: Added forgotten column 'description'.

	  !!! You have to drop your database !!!

	* src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
	  src/main/java/de/intevation/flys/model/DischargeTable.java:

	* src/main/java/de/intevation/flys/importer/AtFileParser.java:
	  Fixed problems with date recognition.

	* src/main/java/de/intevation/flys/importer/ImportGauge.java:
	  Prefix the description of the historical discharge tables 
	  with "Histor.Abflusstafeln".

	* src/main/java/de/intevation/flys/importer/ImportTimeInterval.java:
	  Fixed silly programming error.

2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	  Traverse the "Histor.Abflusstafeln" for the historical
	  discharge tables. too. TODO: Store them in the database.

	* src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
	  Added convinience constructor to set the kind of the
	  discharge table.
	  
2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/ImportRiver.java:
	  Prefix "Zusätzliche Längsschnitte" with "Zus.Längsschnitte"
	  in description.

	  Add convinience constructor with start and stop time.

	* src/main/java/de/intevation/flys/importer/AtFileParser.java:
	  Attach a time interval to a discharge table if we find one.

	* src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
	  Store the reference to the importer model of the 
	  time interval of the discharge table.

2011-05-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/AtFileParser.java:
	  Try to extract time ranges from at files.

	  Parse the "zusaetzliche Laengsschnitte", too.

	* src/main/java/de/intevation/flys/importer/ImportWst.java:
	  Add getter/setter for column 'kind'.

2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/WstParser.java:
	  Fixed flys/issue19: Do not take km column in wst file as a water level.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/model/Gauge.java: Introduced a 'scale'

2011-05-01	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/WstParser.java:
	  Removed superfluous import.

2011-04-20  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/importer/WstColumnValueKey.java:
	  New. This class is used as distinct key of a WstColumnValue - e.g. as
	  key in a map.

	* src/main/java/de/intevation/flys/importer/ImportWst.java: A
	  WstColumnValue cache is build up while initialization. This cache
	  contains all WstColumnValues that exist in the database.

	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java: New
	  constructor that takes the WstColumnValues cache. It is used to
	  initialize new ImportWstColumnValue objects.

	* src/main/java/de/intevation/flys/importer/ImportWstColumnValue.java:
	  Speedup: A ImportWstColumnValue has a WstColumnValues cache that
	  contains all WstColumnValues existing in the database. This makes it
	  unnecessary to call an sql statement for each WstColumnValue to
	  determine its existence in the database.

2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* doc/schema/postgresql.sql, doc/schema/postgresql-cleanup.sql:
	  Added a view 'wst_value_table' which aggregates the data
	  to build w/q value tables.

	  To update existing databases:

	  BEGIN;
	    CREATE VIEW wst_value_table AS
	        SELECT wcv.position AS position,
	               w,
	               (SELECT q
	                FROM   wst_column_q_ranges wcqr
	                       JOIN wst_q_ranges wqr
	                         ON wcqr.wst_q_range_id = wqr.id
	                       JOIN ranges r
	                         ON r.id = wqr.range_id
	                WHERE  wcqr.wst_column_id = wc.id
	                       AND wcv.position BETWEEN r.a AND r.b) AS q,
	               wc.position                                   AS column_pos,
	               w.id                                          AS wst_id
	        FROM   wst_column_values wcv
	               JOIN wst_columns wc
	                 ON wcv.wst_column_id = wc.id
	               JOIN wsts w
	                 ON wc.wst_id = w.id
	        ORDER  BY wcv.position ASC,
	              wc.position DESC;
	  COMMIT;

2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/model/Wst.java:
	  Add forgotten one to many relation Wst -> WstColumn.

2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/ImportWst.java,
	  src/main/java/de/intevation/flys/importer/WstParser.java:
	  Import of q ranges of wst files was totally broken. :-/
	  You have to reimport all your data.

2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:

	  to allow order them by there column position in the original
	  wst file.
	
	  Update existing database with:

	    BEGIN;
	      ALTER TABLE wst_columns ADD COLUMN position int;
	      UPDATE wst_columns w SET 
	        position = id - (SELECT min(id) FROM wst_columns WHERE wst_id = w.wst_id);
	      ALTER TABLE wst_columns ADD CONSTRAINT wst_columns_wst_id_position_key
	        UNIQUE (wst_id, position);
	    COMMIT;

	* src/main/java/de/intevation/flys/model/Wst.java,

	  'amtliche Daten' and so on.

	  Update existing databases with:
	    BEGIN;
	      ALTER TABLE discharge_tables ADD COLUMN kind int NOT NULL DEFAULT 0;
	      ALTER TABLE wsts             ADD COLUMN kind int NOT NULL DEFAULT 0;

2011-03-24	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/model/Gauge.java:
	  Added an one to many relation to the discharge tables of a gauge.

2011-03-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	Finished import of WSTs.

	TODO 1: Speed it up! It takes on a high end machine over 7(!)
	        minutes only for the data of the Saar.
	TODO 2: Double precision floating point representations produced
	        by the the parsers leed to unique constraint violations
			in the backend on a second run. So the import is currently
			only working on freshly initialized data bases.
			More consequent working with BigDecimal and some
			rounding may be of help here.

	* src/main/java/de/intevation/flys/model/WstColumnValue.java:
	  Added convinience constructors.

	* src/main/java/de/intevation/flys/importer/ImportWstColumnValue.java:

2011-03-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/WstParser.java:
	  The unit extraction in the WST parser of desktop FLYS
	  is broken! Add a hack here to repair this for our
	  importer. Desktop FLYS needs a fix, too!

2011-03-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/WstParser.java:
	  Ported some stuff ver from WSTSource.java of desktop flys to
	  parse WST files. TODO: create instances of the import models.

	* src/main/java/de/intevation/flys/utils/StringUtil.java:
	  Copied from desktop flys. Used for some string operations
	  in WST parser.

	* src/main/java/de/intevation/flys/importer/Importer.java:
	  Added system property 'flys.backend.importer.dry.run'.
	  Set to true only the parsing is done and no writing
	  to the backend. Default: false.

	*  src/main/java/de/intevation/flys/App.java,
	   src/main/java/de/intevation/flys/model/MainValueType.java:
