[PATCH v7 2/6] fsmonitor: relocate socket file if .git directory is remote

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Eric DeCosta <edecosta@xxxxxxxxxxxxx>

If the .git directory is on a remote file system, create the socket
file in 'fsmonitor.socketDir' if it is defined, else create it in $HOME.
