commit 8871259c966755233b134a5ddb2b4926539d25c6 Author: Kathy Brade brade@pearlcrescent.com Date: Wed Aug 31 15:26:08 2016 -0400

Bug 14272: Make Tor Launcher work with Unix Domain Socket option

On non-Windows platforms, use a Unix domain socket by default for the Tor control port. New preferences: extensions.torlauncher.control_port_use_socket (Boolean) extensions.torlauncher.control_socket_path (path string) New environment variable: TOR_CONTROL_SOCKET

When starting tor, always include a ControlPort argument so that users can use environment variables to switch between the two control port types.

Add a public TorGetControlSocketFile() function that Torbutton will use to retrieve the socket file (an nsIFile) when a Unix domain socket is in use.

Moved the getTorFile() function to our utilities module. --- src/components/tl-process.js | 253 +++---------------------------------- src/components/tl-protocol.js | 100 ++++++++++++--- src/defaults/preferences/prefs.js | 14 ++- src/modules/tl-util.jsm | 257 +++++++++++++++++++++++++++++++++++++- 4 files changed, 370 insertions(+), 254 deletions(-)
