[tor-commits] [ooni-probe/master] * Modified exception handling in bridget so that ImportErrors from missing
commit 803e24021cc9a1d48eaa4c24b3e19d39bc8be11b
Author: Isis Lovecruft <isis@xxxxxxxxxxxxxx>
Date: Sat Sep 15 03:09:22 2012 +0000
* Modified exception handling in bridget so that ImportErrors from missing
OONI libraries don't clutter the logs.
* Removed txtorcon directory and modified the Makefile so that git clones
dependencies correctly.
* Modified class and import structures in bridget so that txtorcon doesn't
get imported until used, and ImportErrors and missing libraries give
instructions on how to fix any problems.
