Announcements:
* [dgoulet] I know it is quite big and it is fine to not reply but then
that means I'll just go forward with what I think is best and we'll see
from there ("Connection, Channel and Scheduler - An Intense Trek"):

Discussion topics:
* Anybody great in the broader community to highlight this past week?
https://bugs.torproject.org/24148
- [dgoulet: "Hello71" on IRC has been profiling and chasing memleaks
lately, very useful imo. Also, someone submitted a patch to torsocks to
fix it with Rust program #24116]
* Still a few hackerone reports that need to be triaged by the fuzzer
guy.
* Did we finish everything from october?

[might be offline during the meeting, we'll see!]
Last week:
- HSv3 tickets in the 032 milestone.
- Review tickets in the 032 milestone.
- Worked on the prop224 control port specification which I just sent on
tor-dev@ today:
https://lists.torproject.org/pipermail/tor-dev/2017-November/012559.html
- Worked on a tor-dev@ thread about the connection, channel and
scheduler
subsystems:
https://lists.torproject.org/pipermail/tor-dev/2017-November/012559.html
- From that thread ^, the improved scheduler interface came out for
#23993
but not yet public as I'm waiting on possibly more feedback on the
thread before going further.
- We had a series of bad-relays last week that needed some
investigation so
I had to put some times in the health of the network side of things.
- Profiling of 032 relay: #24127
This week:
- Continue the roadmap tasks I have that is the HS circuit timoue
issues
and scheduler work.
- Prop224 control port work aimed at 033 so I want to start the review
as
soon as possible for an "early" merge.
- 032 ticket review and address my tickets as well in that milestone.
