[stem/master] Allowing for negative uptimes prior to tor 0.1.2.7

commit e1a3aba733313c842c24c40ac235c073a548030d Author: Damian Johnson <atagar(a)torproject.org> Date: Thu Apr 19 09:23:27 2012 -0700 Allowing for negative uptimes prior to tor 0.1.2.7 Tor 0.1.2.7 fixed a bug which could result in negative uptime values. Making our descriptor parser accept negative uptimes for tor versions with the bug, and fail validation for later versions. This includes a test with one of the problematic descriptors, checking that we can both parse it, and will fail validation if it was for a later version. Thanks to Karsten for figuring out where these values were coming from! --- stem/descriptor/server_descriptor.py | 24 +++++++++++++-- test/integ/descriptor/data/negative_uptime | 45 ++++++++++++++++++++++++++++ test/integ/descriptor/server_descriptor.py | 24 +++++++++++++++ 3 files changed, 90 insertions(+), 3 deletions(-) diff --git a/stem/descriptor/server_descriptor.py b/stem/descriptor/server_descriptor.py index 7823cf0..f3023a2 100644 --- a/stem/descriptor/server_descriptor.py +++ b/stem/descriptor/server_descriptor.py @@ -473,11 +473,22 @@ class ServerDescriptorV3(stem.descriptor.Descriptor): else: self.hidden_service_dir = ["2"] elif keyword == "uptime": - if not value.isdigit(): + # We need to be tolerant of negative uptimes to accomidate a past tor + # bug... + # + # Changes in version 0.1.2.7-alpha - 2007-02-06 + # - If our system clock jumps back in time, don't publish a negative + # uptime in the descriptor.
