== 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/CIFailures

* Let's check the 0.4.0 release status page.
  See https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorReleases/040Status
  (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:
<-- 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 needs-review tickets, by reviewer:

Here are the outstanding reviews, oldest first, including sbws

* Check rotations at

* 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.

---- 15th April 2019

== Announcements ==

- The master branch is now 0.4.1.x; 0.4.0 development will continue in

We need to prioritize 0.4.0 fixes and reviews in April, because stable
is due on 15 April.

== Discussion ==

Change the meeting time of  Tuesday 23 April to 2300 UTC so we can
include Teor (they are going on leave after that). YES

Change the meeting of Tuesday 7 May at 2300 UTC to Monday 6 May at
1700 UTC because that week Teor will be on leave (no reason to move
meeting). YES

(not much to discuss) What to sponsor for 2020? We could have some
inital thoughts on priorities (not necessary if you don't have time
right now, there will be other opportunities when the grant
oportunities come up). This pad summarize discussion in several places
for the network team:  https://pad.riseup.net/p/Pp3o8e9U6jH5DauxjxK8

(not much to discuss) Google season of docs - we are aplying to
improve technical documentation. We need mentor/s from the team. Their
tasks will be:

help select technical writers

be available for consults that the technical writes may have about documentation

More info at https://developers.google.com/season-of-docs/docs/admin-mentor-responsibilities.
They will need to be register in the website (google acount) and Pili
is coordinating (to submit by April 23rd). PLEASE send a msg to Pili
(cc me) if you want to be a mentor.

(not much to discuss) Roadmap update. Nick and Gaba are going to go
through the roadmap and check if anything needs to be
updated/changed/re-prioritized. It will be in an open session in case
other people in the team want to be involved. Tuesday 23rd of April at
1700 UTC (if we are moving the weekly meeting to later) on jitsi. Send
gaba a msg if you want to attend.

Can people add themselves as owner of the ticket when they start
working on it? for example, is somebody working on #29223 (nickm?)
[done -nickm], #29210 (nickm?) ? [shared between nickm and catalyst
-nickm] thanks

teor says: I can't do bug triage on 29 April, because I'll be away.

Rotation updates (from nickm):

Bug triage

Started with 4 no-component items, some 3 months old.

Started with 55 no-milestone "core tor/tor" items, some 3-7 months
old. Many but not all from Brussels.  Some but not many marked

Had over 100 new incoming emails with bugtracker events to look at.

Tried to assign tags as appropriate; worried that I missed some.
Worried that if I missed some, there's no way to see what the backlog
is for assigning tags.

I don't know how to assign milestones to SBWS tickets.

Current Status: 0 no-component, 0 no-milestone.


Mysterious i386/xenial failures -- not sure how to procede.  (If it's
still happening.)

Resolved #29922, delegated #29645.

Told weasel about a disk-exhaustion condition on jenkins; he resolved it.

Current status: travis and appveyor are passing. Current Tor jenkins
failures are

tor-ci-linux-0.3.5-extra-arm (stretch, armhf) -- Java exception, seems
like a Jenkins issue.

tor-ci-freebsd-amd64-0.2.9/ -- longstanding failure, two unit tests
failing. (test_bt and fgets_eagain)


Started the week with 44 pending coverity issues.

Opened 30146 to work on the most important-looking.  Some children in

Will work on more once the current children of 30146 are solved.

Current status: 42 pending coverity issues; 30146 should solve many, I hope.

"The way you address the problem is by shipping changes not more
slowly, but more QUICKLY.
Fewer, smaller changesets turn into debuggable, understandable deploys."
