== Stuff to do every week =
* How are we managing CI failures from last week? See https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CIFailur...
* Let's check the 0.4.0 release status page. See https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorR... (This page automatically shows the latest trac ticket status.)
* Let's check and update the roadmap. What's done, and what's coming up? We're using a kanban board: https://storm.torproject.org/shared/_mx8PMGOHFBOximocl1gy3COvhLPr6k3Ja7JA1vN... Filter by your name and check the 'in progress' column is correct.
* Check reviewer assignments!
How reviews from last week worked? Any blocker?
Here are the outstanding reviews, oldest first, including sbws https://trac.torproject.org/projects/tor/query?status=needs_review&compo...
* Check rotations at https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/TeamRota... .
* See discussion notes below.
Any blocker from last week?
== Reminders ==
* Remember to "/me status: foo" at least once daily. * Remember that our current code reviews should be done by end-of-week. * Make sure you are in touch with everybody with whom you are doing work for the next releases.
* Remember to fill up the 'actual point' field when you close a ticket. We need those to calculate velocity.
* Check other's people call for help in their entries.
* Remember to book travel for meeting as soon as possible. The rate lock deadline is 10 May, please ask for approval a few days before 10 May.
------------------------------- ---- 23rd April 2019 -------------------------------
== Announcements ==
- The master branch is now 0.4.1.x; 0.4.0 development will continue in maint-0.4.0.
We need to prioritize 0.4.0 fixes and reviews in April, because stable was due on 15 April.
== Discussion ==
Rotation updates:
Bug triage - mikeperry to nick
The Bug Triage role description and queries is on the wiki at:
https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/TeamRota...
Lessons I learned and unanswered questions during bug triage:
WTF is this page? Can I kill it:
- https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/TicketTr...
teor says: this page describes how we triage tickets at the start or end of a release.
We should update it and maybe rename it.
WTF do we do about people using trac-as-support support? I guess
- https://trac.torproject.org/projects/tor/ticket/30192#comment:2
Seems about right to me.
Can I make binding decisions about what to do about components? Does the next
triage ruler get to overturn? ;)
- https://trac.torproject.org/projects/tor/ticket/30250#comment:1
IMO killing components isn't part of ticket triage.
Looked at Core/Tor tickets opened in last 9 days (since I did this Easter Monday
Eve)
- Added points to a couple of my tickets that were created in this window.
- Everything else created recently had points, but many older than 9 days did not.
CI - teor to ahf
https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CIFailur...
I revised #30001, and it is merge_ready for 0.4.0 and later.
This CI ticket was a process failure: it stalled in needs_revision for 2 weeks.
How can we improve this process?
We are making progress on the stem hangs in #29437. Here are the open tickets:
#30235 Tor hangs when asked to change DisableAllSwap over the control port
nickm, can you help with tor_mlockall() hangs?
We keep getting practracker CI failures when we merge forward code from 0.4.0. Here are some possible fixes:
#30051 - Add practracker as a pre-commit and pre-push git hook for frequent coders
this ticket is in merge_ready
Coverity - teor
No new coverity defects this week
Coverity doesn't provide instant feedback, so it's harder to discover bugs at review time. Here is a possible fix:
#30225 Run clang's scan-build in Tor's CI
0.4.0 status: Mostly done or merge_ready. Should we remove the one remaining ticket from 040-must? #29930 Warning: can't unlink unverified-consensus on Windows meeting says: yes
Review status: Stalled reviews - more than 1 week old - what should we do with them? catalyst: #27130 rust dependency updating instructions don't work #29732 Add full-fledged deterministic PRNG support for testing
teor: #23588 Write fascist_firewall_choose_address_ls() and use it in hs_get_extend_info_from_lspecs() I will review this ticket before I go away (but after I do my feedback)
mikeperry: #30109 Document that MapAddress is automatically strict, but does not handle redirects #30112 Fix outdated comments in dirserv_read_measured_bandwidths() #30147 Fix "high-impact" coverity false-positive warnings outside of tests #30148 Fix infrequent, unlikely memory leak on failure to create keys directory
there is a proposal to look for funding to work on mobile onion services (from a partner that may need them) for 2020. It would be a 1 engineer for 1 year and it could include other onion services stuff. Do we look for funding for it? <--- It could be started after April 2020 if we look for funding now. --gaba
There is too much information in this pad. This is a process failure. Can we split the pad up into: Everyone must do this task this week / know this thing this week / discuss this issue this week Discussion queue (topics that are important, urgent, and affect most people go at the top) Information list
=== teor's handover ===
==== sbws ====
I am still spending a lot of time on sbws designs and design reviews: Let's use the tor proposals process for sbws: https://lists.torproject.org/pipermail/tor-dev/2019-April/013785.html
Let's block all sbws merges until I get back, unless an urgent bug comes up. I don't think adding more load to the team is a good idea right now, so our best option is slowing sbws and other non-funded work.
Here are the active sbws tickets:
Is it acceptable that SBWS consistently reports 6200 relays, 1000 fewer than Torflow's 7200 universe? https://trac.torproject.org/projects/tor/ticket/29710 Work out why recent_measurements_excluded_few_count=733 and its children. https://trac.torproject.org/projects/tor/ticket/30227 Add additional bandwidth file headers in sbws 1.2, and children. https://trac.torproject.org/projects/tor/ticket/30255
We can make future hand overs easier by assigning two paid staff members to help out with sbws.
==== Mainline Merges ====
Now dgoulet is back, I have stopped doing mainline merges, except for urgent CI fixes: https://lists.torproject.org/pipermail/tor-dev/2019-April/013779.html
==== Backports ====
Let's block most backport merges until I come back.
Who will do urgent CI backports? nickm
0.3.5 and later are affected by the stem failures, if we fix the tor_mlockall() bug, we should backport that to 0.3.5 But maybe we should test it first, so that might mean disabling stem in 0.3.5 and 0.4.0?
==== Reviews ====
Please don't put me on reviews until 27 May. (I will be dealing with backlogs when I get back.) I have un-assigned myself from all open tickets where I am the reviewer.
==== Rotations ====
See my rotation handover below.
Please don't put me on rotations until 27 May. (I will be dealing with backlogs when I get back.) I can't do bug triage on 29 April, because I'll be away. We don't have rotations for May yet.
==== Roadmap ====
I don't think I will make any progress on PrivCount while I am away. Can we please assign someone else to help me with PrivCount? [Nickm wants to do privcount stuff; anybody else?]

- Send feedback to Kat.
Network team:
- Confirmed problem for #29930, discussed possibly solutions with Nick today.
- Managed to reproduce #29645 in a very flaky manner on my desktop under very heavy load, but cannot figure out what causes it.
Misc:
- Went to holiday house for easter.

juga: Week of 04/22 (plan): - Depending on which has higher priority, work on #29710 children or #30255 children (it seems this needs more discussion and or proposals)
Help with: - Question 1: teor or network-team: which on do you think has higher priority, #29710 or #30255? - Question 2: teor or network-team: longclaw's sbws 1.1.0 has been running for more than 1 week, do we want to start running sbws 1.1.0 on basted or should #29710 and/or #30255 be solved first? [Nick will try to answer these questions if teor doesn't.]
