Meeting notes from previous weeks:
* 0.3.3.x is in feature-freeze. No new features (except for
#24902, which has permission.).
* 0.3.3.2-alpha came out Saturday 10 Feb.
* Please, work on bugfixes! It would be great to have this release
release on time. (Planned date is 15 April)
* There are tons of tiny 0.3.3.x tickets. Maybe if you can do one
of them in <X minutes for some small X, you should just do it?
* We moved the hackfest 2 days later (Wednesday 30th - Sunday 3rd)
to avoid clashing with Memorial Day
dgoulet, teor, and isabela are organising it off-list.
See the network-team list for updates.
* No GSoC for Tor :'( [this time]
* Jon is booking accommodation for the May hackfest.
* The 0.3.4.x merge window opened on Feb 15.
* Review-group-32 is open! There are 2 tickets assigned to teor
and mikeperry to review.
Maybe we can move on to review-group-33?
* Nick just made a review-group-33. Please take tickets to review.

If you review tickets, feel free to add a column with your name.

taken this week, but its empty for next week:
* isis cannot attend Rome :(
* prop#245 + prop#282 meeting today (tuesday) at 23:00 UTC
- Can we remove the *.nmake files in tor.git? I have a feeling
that they are unmaintained/unused?
- Is all the dates final for the May hackfest? (would like to
order tickets early from Europe while they are cheap).
- Isabela's heat-mapping exercise with areas of tor work: what are
our priorities? https://pad.riseup.net/p/38VbTZUIzG4X
* Last week:
- Implemented and tested more Experimental PrivCount circuit
and onion service stats
(1.5 features left, and then it's feature-complete. I hope!)
- More May hackfest planning
- More Proposal meetings
- Detailed design and numerical analysis for uniform random in
Rust, but still no code
- Reviewed a few tickets, merged a chutney network for bwscanner
* This week:
- Final Experimental PrivCount features (no, really, this week)
- Eventually make a trac user page that lists the tickets I'm
working on in priority order.
Add something similar to the network team queries page.
- I should get time to review or revise more tickets later this week
last week (2018-W07):
- reviewed #25185 (Rust cstr stuff)
- learned more Rust stuff, including some doc-test things
- patch for #21074 check-changes
- travel logistics for Rome meeting and Seattle hackfest
- CoC and SoV feedback
- helped pastly with IRC moderation stuff
this week (2018-W08):
- work on 0.3.3 bugs

* Last week:
- We got #24902 backported \o/
- Discussion with armadev on #25226 for which it could be that we want a
hard limit of cell queue size per circuit.
- Did a branch for #17945 as a possible solution. Need feedback.
- Opened and worked on #25268 to remove the cmux round-robin algorithm.
- I've also started working on a branch to improve our fast path (per cell)
within the cmux subsystem. It touches also #25152. Not ready for merge or
anything, it was more experimental to see how that would play out.
- Worked with asn on the subsystem maintainer sheet. *PLEASE FILL IT UP*
- A little bit of May/June Hackfest logistics with Jon.
- Was quite a week for bad relays so spent some time there.
- Helping atagar with some HSv3 questions and examples for Stem integration
- Sent to tor-dev@ my 034 enhancement plans:
- Some ticket triage including 033-must tagging. See timeline:
* This week:
- Hope to work on 034 enhancement so we can get them early in the merge
window. Especially the scheduler stuff.
- 033 tickets are still a reality.
- Get #24767 in a merge_ready state (asn did a first review)
* Last week:

- More roadmapping fun.
- More reviews/bugfixes.
- Think about HS statistics that we could gather (reply to teor's email).
- Reorganizing and refactoring vanguards repo
- Reviewed #22926
- Reviewed guardraction code - are we sure we want to rip it out
rather than just disable torrc?
[asn: i think we want to rip it off to simplify the codebase.
otherwise we could keep it lingering on until and if we have firepower
to fix it...] [mike: do we believe that a new from-scratch
implementation will be simpler?] [asn: no. i think we just realize we
wont ever have enough time to fix it and maintain it] [mike: hrmm..
that seems defeatist and potentially wasteful :/] [asn: might be. it's
just that the code has been sitting around for many releases and it's
been broken and no one wants to fix it or maintain it. also dirauth
ops are complaining about the python script and we should tell them to
kill it] [mike: it seems like disabling and deprecating the python
script can be separate from removing all of the functionality from
tor-core... is this the type of thing that will always be easier to do
in an external program, because of statekeeping?] [asn: yes it's
because of statekeeping that we do it as external. and i agree that
perhap disabling the python script is separate from removing code from
tor. as an argument for keeping it, the guardfraction tor code is
fairly isolated and abstracted from the rest of the code]
- Walked over S8 roadmap tasks.
- Baselined some memory usage experiments with Shadow+dtrace that
was done with tor+simpleperf before.
