[bridgedb/master] Catch DescriptorWarnings and log them when we get identical descriptors.
by isis＠torproject.org 25 Mar '15

25 Mar '15

commit a27d79055d7b8de22a069c6ab8ee6ce2ffcd459a Author: Isis Lovecruft <isis(a)torproject.org> Date: Sat Mar 21 03:31:06 2015 +0000 Catch DescriptorWarnings and log them when we get identical descriptors. It turns out this actually does happen. Not very many times, though. When redeploying BridgeDB-0.3.0 with the new Stem descriptor parsers from #9380, [0] there were two bridges who had completely identical descriptor (including identical timestamps). Each of those bridges had exactly one perfectly identical duplicate descriptor each, and each bridge was quite new, having just appeared within the last 8 hours. Previously, the BridgeDB process would die because we didn't catch these errors. This fixes that.

[bridgedb/master] Fix error for initializeGnuPG() return value when signing fails.
by isis＠torproject.org 25 Mar '15

25 Mar '15

commit 105de16be5962ecdc6979936da17bb587aece69b Author: Isis Lovecruft <isis(a)torproject.org> Date: Sat Mar 21 03:36:48 2015 +0000 Fix error for initializeGnuPG() return value when signing fails. When the test signing in bridgedb.crypto.initializeGnuPG() fails, the return value would be `None`, rather than the gpg interface and the signing function, `(gpg, gpgSignMessage)`, or `(None, None)` as it does with the other failure modes. This would cause the EmailServerContext to raise a TypeError because `None` is not iterable, and cannot be assigned to two variables. We now return `(None, None)` when the test signing fails. This is a bugfix on #10385.
