[stem/master] Dropping the memory usage assertion when reading descriptors

[tor/master] Stop frobbing timestamp_dirty as our sole means to mark circuits unusable
by nickm＠torproject.org 18 Mar '13

18 Mar '13

commit 62fb209d837f3f5510075ef8bdb6e231ebdfa9bc Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue Feb 19 18:29:17 2013 -0500 Stop frobbing timestamp_dirty as our sole means to mark circuits unusable In a number of places, we decrement timestamp_dirty by MaxCircuitDirtiness in order to mark a stream as "unusable for any new connections. This pattern sucks for a few reasons: * It is nonobvious. * It is error-prone: decrementing 0 can be a bad choice indeed. * It really wants to have a function. It can also introduce bugs if the system time jumps backwards, or if MaxCircuitDirtiness is increased. So in this patch, I add an unusable_for_new_conns flag to origin_circuit_t, make it get checked everywhere it should (I looked for things that tested timestamp_dirty), and add a new function to frob it. For now, the new function does still frob timestamp_dirty (after checking for underflow and whatnot), in case I missed any cases that should be checking unusable_for_new_conns. Fixes bug 6174. We first used this pattern in 516ef41ac1fd26f338c, which I think was in 0.0.2pre26 (but it could have been 0.0.2pre27). --- changes/bug6174 | 6 ++++++ src/or/circuitlist.c | 9 ++++----- src/or/circuituse.c | 36 +++++++++++++++++++++++++++++++++--- src/or/circuituse.h | 1 + src/or/connection_edge.c | 18 ++++++------------ src/or/or.h | 4 ++++ src/or/relay.c | 5 ++--- 7 files changed, 56 insertions(+), 23 deletions(-) diff --git a/changes/bug6174 b/changes/bug6174 new file mode 100644 index 0000000..79d2930 --- /dev/null +++ b/changes/bug6174 @@ -0,0 +1,6 @@ + o Major bugfixes: + - When we mark a circuit as unusable for new circuits, have it + continue to be unusable for new circuits even if MaxCircuitDirtiness + is increased too much at the wrong time, or the system clock jumped + backwards.
