== 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/1Ufrun1khEo5Cwd6OwngERn829wU3W3eskdrr...

* Check reviewer assignments at https://docs.google.com/spreadsheets/d/1Ufrun1khEo5Cwd6OwngERn829wU3W3eskdrr...

* Check rotations at https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/TeamRota...

== 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 0.3.4.x work.

* Important dates: * May 1, 2018 -- 0.2.5 is no longer supported:

https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorR... * May 15, 2018 -- 0.3.4.x feature freeze! 3 WEEKS LEFT.

- *OUR BIG PRIORITY **SHOULD BE **TO GET ALL FEATURES IN FOR 034 BEFORE ANYTHING ELSE.*

- * Lets not wait for the review assignement sheet for any of those or roadmap items.*

* Remember: don't spend more than a day working on anything that isn't on the 033 or 034 milestones.

* juga is working on bandwidth measurement for Tor's Summer of Privacy. Congratulations!

== Discussion ==

* Should 0.3.4 be a long-term support release? How do we pick our next LTS? -NM

- Can we just tell Debian to use it as a LTS? What about other platforms? - teor

* Are we ready to release 0.3.3? -NM

- [dgoulet] We should get the TROVE finalized. Apart from that, I think it is.

- [ahf] I still have #25245 open, I do have a patch to do some diagnostics, but it's very annoying to reproduce locally. It's marked priority = very high, but I don't know if we think it's a blocker?

== Updates ==

asn: [Migh be off for May 1st excursion at the time of the meeting.] Last week: - Reviewed and helped with #25870. This is complex stuff! To better understand the ticket, I wrote some initial unittests for path selection for normal exit circuits and vanguards. They are still quite simple but they can be the basis of something good. - Pushed bugfixes and features to the vanguard simulator (#23978) based on Mike's testing. - Reviewed #23693. - Provided feedback to the 2-guard proposal thread. - Gave a bit of testing to haxxpop's v3 client auth branch. Seems to work! I also motivated some more people to try it out and find bugs. Next step is to find time for code review. We are hoping for 035 inclusion. - Discussed v3 intro auth with haxxpop. - Wrote patch for #25843 and got it merged. - Replied to "[tor-dev] onion v2 deprecation plan?" thread. - Suggested some tasks to our ahmia SoP student. This week: - Continue discussion on the 2-guard proposal thread. We are doing good progress. - Discuss with Mike what's needed next for the vanguard simulator. - Triage tickets out of 034 with my name that I don't have time for. Most of them were the result of 033 -> 034 triaging. - Hopefully find some time for #25552.

Mike: - Reviewed #24734, wrote a couple fixups forit. - Worked on #25870 (vanguard path restrictions) with asn. - Proposal 291 mailinglist posts (enumerated 8 properties defenses have and developed one that got all of them) - Refined #25903 (CIRC_BW events that help check for dropped-cell side channels); updated vanguard repo to use them; tested them. - Reviewed #25843 (NumEntryGuards param). asn - are you sure that it is influencing our dirguards? it looks like no.

catalyst: last week (2018-W17): - investigated some unexplained test coverage fluctuations revealed by coveralls.io - opened #25908 to stabilize test coverage. thanks nickm for doing some inital data gathering! - more call stack analysis for #25061 - deferred #25061 to 034 - reviewed #19429 (compatibility with openssl-1.1 no-deprecated) - patch for #25936 (display test-suite.log from the correct location when doing a distcheck build in travis) - worked on #25756 (relax timestamp tolerance for early consensus) this week (2018-W18): - finish #25756 - write some summary of investigations to date on #25061 - reviews - other 033, 034 bug fixes as needed

teor: * Last week: * collecting privacy-preserving statistics is still time-consuming * Bandwidth file spec revisions, we should have tested it with tor first :-) * Continued to help with bandwidth measurement (sbws) * A few code and spec reviews * CC'd specific people about old trac milestones * This week: * Analyse the last collection results * Configure and schedule the next collection(s) * Start writing up & reviewing others' write-ups * Try to keep up with the bandwidth stuff

dgoulet: Last week: * Fixed tickets (see Timeline). * Reviwed and worked on #25500 child tickets with nickm. * Finalized dirauth modularization with #25610, working with ahf on that. It is in needs_review and a biggy! * The annoying warning on 034 has been fixed! #25577 This week: * Continue on #25500 child tickets with nickm. * Prioritize #25610 if a review comes in. * Depending on the two things above goes, I can get on the roadmap item #25552 (HSDir rev counter issue) or the wide CREATE cell work (#24986). * Name of the game for me until the freeze in 15 days is to prioritize big patches and features for 034 on our roadmap.

ahf: Last week: Sponsor 8: - Went over data submission for our Onion Service speed test and ensured everything was running OK. - Worked with David on going over the dir auth module code. - Submitted patch for #25953.
