commit 92ac1930143e51689396563877087d1070a246bd Author: Damian Johnson <atagar@torproject.org> Date: Sat Oct 15 14:03:32 2011 -0700 Adding OSX support for the getPwd utility BSD platforms lack either pwdx or proc contents with this information. However, this is available via lsof. Using this for BSD platforms. This was tested by running sysTools.getPwd() on OSX - hopefully it should work on Free/OpenBSD too. Fix is thanks to Sebastian. https://trac.torproject.org/projects/tor/ticket/4236 --- src/util/sysTools.py | 17 +++++++++++++++++ 1 files changed, 17 insertions(+), 0 deletions(-) diff --git a/src/util/sysTools.py b/src/util/sysTools.py index 98361e5..4bb0667 100644 --- a/src/util/sysTools.py +++ b/src/util/sysTools.py @@ -174,6 +174,23 @@ def getPwd(pid): PWD_CACHE[pid] = pwd return pwd except IOError: pass # fall back to pwdx + elif os.uname()[0] in ("Darwin", "FreeBSD", "OpenBSD"): + # BSD neither useres the above proc info nor does it have pwdx.
