ShapefileDataStore uses memory-mapped I/O even when told not to
---------------------------------------------------------------
Key: GEOT-817
URL: http://jira.codehaus.org/browse/GEOT-817
Project: GeoTools
Type: Bug
Components: shapefile
Versions: 2.1.0, 2.1.1, 2.2.M0, 2.2.M1, 2.2.M2, 2.2-RC0, 2.2-RC1
Environment: Linux, kernel version 2.4.27 and 2.6.8.
Reporter: Tuure Laurinolli
Assigned to: Ian Wolfe Schneider
When trying to get the schema from a newly opened ShapeFileDataStore, my
program fails with a mmap error deep down in Sun's nio. The workaround to this
problem would be reading the file without mmapping it, but ShapefileDataStore
fails to obery it's useMemoryMapped-constructor flag.
The problem is caused by line 487 in 2.1.0 ShapefileDataStore.java - it creates
a subordinate DbaseFileReader without passing on the useMemoryMappedBuffer
flag. This line of code is unchanged in newer versions.
