Jerome Lacoste updated VFS-186:
-------------------------------
Attachment: VFS-186.diff
This patch is not very pretty and still contains some printouts.... I will
clean it later if you want.
Details
SftpFileSystem
* synchronize access around the "pooled" idleChannel
SftpFileObject
* remove the synchronization added by VFS-113 (I think it is more of a hack
than a correct solution. Synchronization should be on the file system
* add a call to putChannel (not 100% sure it was needed, but there's a lack of
symmetry if it isn't there.
This doesn't seem to affect the performance and remove the instability we had.
We still have one issue under investigation: jsch disconnecting with the
following message:
SSH_MSG_DISCONNECT: 2 Could not create socket pairs: Too many open files

>
> We wrote a simple unit test to stress test commons-vfs sftp implementation.
> We used multiple-threads.
> We ran into various issues, some in jsch 0.1.36, some in commons-vfs. After
> applying the following patch (in combination with those for jsch),
> commons-vfs became much more reliable.
