Concurrent feature modification blocks in PostGIS
-------------------------------------------------
Key: GEOT-897
URL: http://jira.codehaus.org/browse/GEOT-897
Project: GeoTools
Issue Type: Bug
Components: data jdbc, data postgis
Reporter: Cory Horner
Assigned To: Cory Horner
Priority: Critical
Fix For: 2.2-RC5, 2.3.M0
Current versions of PostGIS lock on the row level. If one user has a row
locked for modification (in a transaction), a second user will experience an
application lockup while waiting to acquire the lock (the lock is released
during commit or rollback). If the first user has crashed their application
(leaving the connection open), or gone for coffee, it is game over for the
second user.
