[stem/master] ControlMessage equality and hashing
by atagar＠torproject.org 07 Aug '18

07 Aug '18

commit b48ce682ef1a5fc1d4237d106700ec929f49246b Author: Damian Johnson <atagar(a)torproject.org> Date: Tue Aug 7 15:04:20 2018 -0700 ControlMessage equality and hashing Interesting! Previously I implemented comparability for a single event type but that's all. I'm surprised we've gone this long without needing it. Messages have only three things we need to account for in the hash... * The message content (ie. the bytes we got from tor). * The message class, if we've casted ourselves to something. * The arrived_at timestamp if this is an event. That's it. Everything else is derived from those. Changing hash_attr()'s parent argument back to a class because a boolean makes it pretty likely we'll hit an invinite loop. In this case we hit it because we had the following object hierarchy... ControlMessage <= has a hash method Event <= has a hash method BandwidthEvent <= our object type If our Event class' hash method calls super it will return the Event class, not ControlMessage, causing us to loop indefinitely. Changing hash_attr() so it takes an explicit reference for our parent instead. --- docs/change_log.rst | 1 + stem/__init__.py | 2 +- stem/directory.py | 4 ++-- stem/response/__init__.py | 17 +++++++++++--- stem/response/events.py | 43 ++++++++++------------------------- stem/util/__init__.py | 6 +++-- test/unit/response/control_message.py | 24 +++++++++++++++++++ 7 files changed, 58 insertions(+), 39 deletions(-) diff --git a/docs/change_log.rst b/docs/change_log.rst index 282a02c8..362e4e10 100644 --- a/docs/change_log.rst +++ b/docs/change_log.rst @@ -58,6 +58,7 @@ The following are only available within Stem's `git repository * Added the delivered_read, delivered_written, overhead_read, and overhead_written attributes to :class:`~stem.response.events.CircuitBandwidthEvent` (:spec:`fbb38ec`) * The *config* attribute of :class:`~stem.response.events.ConfChangedEvent` couldn't represent tor configuration options with multiple values.

[tor/master] When enabling periodic events, schedule but don't run them immediately.

commit 176999fd955dea5916a560374db7d4efd3a1dad1 Author: Nick Mathewson <nickm(a)torproject.org> Date: Thu Aug 2 10:03:24 2018 -0400 When enabling periodic events, schedule but don't run them immediately. When we fixed 25939 in f7633c1fcaefe72bf97c001bab9062132c919996, we introduced a call to rescan_periodic_events() from inside the onion service logic. But this meant that we could rescan the event list -- thereby running event callbacks! -- from inside the hidden service code. This could cause us to run some of our event callbacks from an inconsistent state, if we were in the middle of changing options. A related bug (#25761) prevented us from rescanning our periodic events as appropriate, but when we fixed THAT one, this bug reared its ugly head. The fix here is that "enabling" an event should cause us to run it from the event loop, but not immediately from the point where we enable it.
