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

	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
	  Fixed silly bug. Set flush mode back to auto because
	  manual flushing causes some undetermined problems.

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

	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
	  Do not load _all_ values from discharge tables and
	  wst columns. This is extremly slow and will lead
	  to OOM if more rivers are imported. Now only the
	  last 20 columns und discharge tables are cached.

	* src/main/java/de/intevation/flys/importer/ValueKey.java:
	  New. Key for caching discharge table values and wst
	  column values.

	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
	  Fixed bug in equals().

	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java:
	  Removed too eloquent debug output.

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:
	  Add the forgotten description property.

	* 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>

	* src/main/java/de/intevation/flys/importer/AtFileParser.java:
	  Inject 'kind' attribute.

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

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

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

	  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.

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

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

	* src/main/java/de/intevation/flys/importer/ImportRiver.java:
	  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'
	  that is used to adjust the range of min/max W values.

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:

	  point of the river.

2011-04-15	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* doc/schema/postgresql.sql: Added 'position' column to wst_columns
	  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,
	  src/main/java/de/intevation/flys/model/WstColumn.java:
	  Adjusted models.

	* src/main/java/de/intevation/flys/importer/ImportWst.java,
	  src/main/java/de/intevation/flys/importer/ImportWstColumn.java:

	  kinds like 'Haupt-WST', 'zusaetzliche Laengsschnitte',
	  '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;
	    COMMIT;

	  src/main/java/de/intevation/flys/importer/ImportWst.java,
	  src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
	  Adjusted the models.

2011-04-15  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/backend/SessionHolder.java: Moved to
	  this module from flys-artifacts. This is necessary to get access to the
	  current session in this module as well.

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:

	  Add a list of the ImportWstColumnValues produced by the WST parser.

	* src/main/java/de/intevation/flys/importer/WstParser.java: Add
	  the (km, w) values to the ImportWstColumns.

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

	* src/main/java/de/intevation/flys/importer/WstParser.java:
	  Build models for wsts, wst columns and q ranges and
	  store them in the backend. TODO: store the w values.

	* src/main/java/de/intevation/flys/model/WstQRange.java
	  src/main/java/de/intevation/flys/model/Wst.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:
