TorCtl Misparsing Escaped Cookie Paths
The proper handling for the cookie file paths are actually kinda complicated since it can contain escape characters ("Controllers MUST handle escape sequences inside this string." ). Functionally this means that its been processed by tor's "esc_for_log" function in 'common/util.c'.
TorCtl not only doesn't unescape paths, but also chokes if there's an escaped quote within it. For instance...
atagar@morrigan:~/Desktop/arm/src$ cat ~/.tor/torrc SocksPort 0 ControlPort 9051 CookieAuthentication 1 DataDirectory /tmp/my data"dir/ atagar@morrigan:~/Desktop/arm/src$ python >>> from TorCtl import TorCtl >>> conn = TorCtl.connect() INFO[Sat Oct 29 10:46:55 2011]:Event loop received close message.
