reading a RAM FileSystem file fails because it never returns EOF -1.
--------------------------------------------------------------------
Key: VFS-407
URL: https://issues.apache.org/jira/browse/VFS-407
Project: Commons VFS
Issue Type: Bug
Affects Versions: 2.0
Reporter: Miroslav Pokorny
RamFileRandomAccessContent
ORIGINAL
@Override
public int read(byte[] b, int off, int len) throws IOException
{
int retLen = Math.min(len, getLeftBytes());
RamFileRandomAccessContent.this.readFully(b, off, retLen);
return retLen;
}
// getLeftBytes() returns 0 when empty. retLen is 0 when empty and never -1.
FIXED
// HACK Patched to return -1 when empty previously it returned 0
@Override
public int read(final byte[] b, final int off, final int len)
throws IOException {
int retLen = InputStreams.END;
final int left = RamFileRandomAccessContent.this.getLeftBytes();
if (left > 0) {
retLen = Math.min(len, left);
RamFileRandomAccessContent.this.readFully(b, off, retLen);
}
return retLen;
}
