== Stuff to do every week =
* Let's check and update the roadmap. What's done, and what's coming up?
url to roadmap:
https://docs.google.com/spreadsheets/d/1Ufrun1khEo5Cwd6OwngERn829wU3W3eskdrriaYfUBQ/edit#gid=856122210yy
* Check reviewer assignments at
https://docs.google.com/spreadsheets/d/1Ufrun1khEo5Cwd6OwngERn829wU3W3eskdrriaYfUBQ/edit#gid=95993070
* Also, let's check for things we need update on our spreadsheet! Are
there important documents we should link to? Things we should
archive?
* Check rotations at
https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/TeamRotations
* Community guides, it's time to hand off to the next guide!
* Let's look at proposed tickets!
== Announcements ==
* 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 release!
* The git master branch is now 0.3.5!
== Discussion ==
Any volunteers for handling backports to stable?
Any volunteers for leading 0.3.5 triage process? (Labeling tickts,
asking people to label tickets, etc)?
How can we help Ooni integrate and test Tor?
https://github.com/measurement-kit/measurement-kit/issues/86
(teor added a comment about tor_api.h)
[I think that ticket may be stale: simone knows about tor_api.h and
has been working with it, IIUC. -nm]
How can we help Ooni integrate and test pluggable transports?
https://github.com/measurement-kit/measurement-kit/issues/1426
Ooni tests reachability to the default Tor Browser bridge IPs and
ports, but how can they embed the protocols?
[This is trickier.
At least four ISPs in two countries have blocked most of the January
2018 list of fallbacks.
Do we want to do a fallback rebuild in the next few weeks?
When is our next stable Tor release?
Update Steps: https://trac.torproject.org/projects/tor/wiki/doc/UpdatingFallbackDirectoryMirrors
Master ticket: https://trac.torproject.org/projects/tor/ticket/24786
Step 1: Ask Relay Operators to Opt-In:
https://trac.torproject.org/projects/tor/ticket/24804
[I am fine with doing this on whatever schedule you like. -nm]
[I have talked with teor, and will handle the rebuild if/when
desired. -phoul]
Roger's thoughts: "if it's easy to make a new list, let's try it"
"if they block the new list, we've learned something"
"oh i wonder how tor behaves when half its fallbackdir list is
blocked. like, do we have to throw out the existing ones,
in order to give people a list that isn't half blocked in india
andvenezuela? that would be sad"
[Clients need >30% of the list to be unblocked to bootstrap reliably.
Currently 97% of the list is blocked at one of the ISPs.
So if we can get 50 new or rotated fallbacks, let's update the list.
We have 13 new or changed fallbacks on #24805.
We could get up to 35 rotated fallbacks from large operators in the
existing whitelist.
(If we aim for 200 fallbacks rather than 150, we can bump to 200 *
5% = 10 per operator and get 15 extra fallbacks from large operators.)
Let's see if we can get ~40 more relays opted-in by emailing
tor-relays and large operators? -teor]
Or should we write blog posts / tweets / etc. about bridges?
(Or both?)
[Both seems good. -nm]
What are next steps on SimonHF's "trace" proposal?

== Updates ==
Nick:
* Last week:
* Split roughly half of src/common into src/libs (#26481) per
refactoring plan (https://pad.riseup.net/p/cJUbdx0c7IzM-keep). My
goal is to have src/common completely gone in 0.3.5, replaced by a set
of libraries.
* Review and merge various stuff
* Solved #25386 (rust linking), except not really. :/
* Worked on open appveyor issues
* Wrote a utility to handle changing moving include files and
automatically fixing up whatever uses them.
* Made "src" the top of our include path. Now one includes
"or/or.h" rather than or.h.
* Wrote a utility to make sure that modules aren't including
other modules when they shouldn't.
* This week:
* Get 26479 and 26480 (appveyor failures) fixed so I can
release 0.3.4.3-alpha.
* Release 0.3.4.3-alpha.
* Prepare for an 0.3.3.6 release
* Continue refacatoring src/common
* Make the dependencies in src/libs acyclic.
* Plan an order of operations for splitting src/or.
* Open tickets about remaining cases of #25386 (sanitizers, rustdoc).
* Document src/lib.
* Make requested post-merge cleanup changes in src/lib structure.
Dgoulet:
* Offline this Monday for a holiday!

Last week:
Sponsor 8:
- Worked on better process handling for #25502 - looked into what
is needed to do what I think is needed on all our platforms
including Windows.
- Looked at mio/miow from the Rust people.
- Tried to write a small IOCP backend for libevent
that fakes "readiness" in the same way that Mio does it.
Misc:
- Coverity duty: Lots of issues found. A lot of them are fixed in
#26467, but two "classes" of bugs remain unfixed. Would like some
help to figure out what the issue is there.
- CI duty: Thanks to Nick and Taylor for diving into the Rust issue!
- Wrote a very minimal Sandbox for MacOS (#26374) in
https://github.com/ahf/tor/tree/wip-macos-sandbox.
- Got introduced to the build process of Tor Browser.
- Investigated Sandbox options for Windows.
This week:
Sponsor 8:
- Continue with development of process handling code for #25502
Misc:
- Finish off two remaining classes of Coverity issues for #26467.

this week (2018-W26):
- CI rotation
- more work on big patches doc
- more Rust build fixes

- does someone more familiar with trunnel want to swap reviews
on #3569 (refactor SOCKS parsing)?
[Nick will]
