TransactionStateDiff incorrectly calculating getCount
-----------------------------------------------------
Key: GEOT-3545
URL: http://jira.codehaus.org/browse/GEOT-3545
Project: GeoTools
Issue Type: Bug
Components: data, data property, data shapefile
Affects Versions: 8-M0
Reporter: Jody Garnett
Priority: Trivial
Fix For: 8-M0
In updating the PropertyDataStore implementation of FeatureStore I ran into a
case where the ProperyDataStore.getCount method was returning -1; rather than
calling super.
The super class, AbstractFeatureStore implements getCount by:
1. using AbstractDataStore.getCount to generate the total number of features
present at the file level on Transaction.AUTO_COMMIT
2. Modifying this total based on the contents of TransactionStateDiff
(ie removes -1 from the total, adds increase the total, modifications do not
change the
total).
The problem is that this work produces the wrong result as shown by the
transaction independence test implemented by PropertyDataStoreTest.
For now the Trivial workaround is to return -1; and not engage the above code.
No word on if ShapefileDataStore is effected.
