Description

It appears that code generation will fail silently (no error message and a 0 return code) when the current user does not have permission to create a directory in the current working directory (the "gen-XXX" directory for the corresponding generated bindings).

I was able to easily reproduce this by:

$ cd /
$ thrift --gen py /path/to/some/idl.thrift
$ echo $?
0
$ ls gen-py
ls: gen-py: No such file or directory

I verified this happens on 0.9.0, 0.9.3, and 1.0.0-dev (974c99ba38b02288daf05229cdf34e60261d2d01e). I have to assume it also happens on 0.9.1 and 0.9.2 but I didn't explicitly verify that.

Ideally, the user would get a "Permission denied" type of error message and we'd see a non-zero exit code for the thrift invocation.
