== Stuff to do every week =
* Let's check and update the roadmap. What's done, and what's coming up?
We're using a kanban now:
https://storm.torproject.org/shared/_mx8PMGOHFBOximocl1gy3COvhLPr6k3Ja7JA1vNIXr
* Check reviewer assignments!
Here are the needs-review tickets, by reviewer:
https://trac.torproject.org/projects/tor/query?status=needs_review&reviewer=!&max=300&col=id&col=summary&col=reviewer&col=status&col=type&col=priority&col=milestone&col=component&order=reviewer&report=82
Here are the outstanding reviews, oldest first:
https://trac.torproject.org/projects/tor/query?status=needs_review&component=Core+Tor%2FTor&col=id&col=summary&col=status&col=type&col=priority&col=milestone&col=changetime&col=reviewer&col=keywords&order=changetime
Including sbws:
https://trac.torproject.org/projects/tor/query?status=needs_review&component=Core+Tor%2FTor&or&status=needs_review&component=Core+Tor%2Fsbws&col=id&col=summary&col=status&col=type&col=priority&col=milestone&col=changetime&col=reviewer&col=keywords&order=changetime
* 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
Core Tor/sbws is now part of the bug triage, CI, and reviewer assignment roles
== 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 actual point when you finish a task (as well as
update the estimate when starting the issue).
* Add planned PTO to the calendar
https://storm.torproject.org/shared/ISA5L5nH0Xu88iqSCx9ZjCXYSMKOBTdbUeWarbdGmxx
* Check other's people call for help in their entries.

---- 11 February 2019
-------------------------------
== Announcements ==
== Discussion ==
== Proposed tickets ==
* Teor is bringing a proposal for proposed ticket
https://pad.riseup.net/p/network-team-triage-2018
Reminder: please add points estimates to proposed tickets!
Please tag proposed tickets with 040-proposed or 041-proposed, and add
a points estimate (in days).
If the ticket needs to be added to the roadmap, put it on the list
below, so we can talk about it at the meeting.
=== 035-proposed ===
#29042 Error loading private key after 0.3.5.7 upgrade needs_review
#28248 Add comments around rust compilation flags
accepted <=== accepted if Nick can do it quickly.
#29134 Document the max number of v3 client auths I can make new
=== 040-proposed ===
Capacity Estimate
TODO: turn capacity estimates into a script or spreadsheet
?? points of proposed tickets
?? points of accepted tickets
?? days left until the 0.4.0 release, approximately ?? * 0.36 = ??
coding days per person
(see below for calculations)
List of tickets that aren't on the roadmap
#29040 -- Tor crashes if ClientOnionAuthDir contains more than one
public key for a hidden service (new) <-- defer deciding until asn &
dgoulet input
#28363 -- Make a torrc option which prevents Tor from falling asleep
Is this a duplicate of one of our Sponsor 8 dormant mode tickets?
Open 040-proposed tickets:
https://trac.torproject.org/projects/tor/report/77
Open 040-proposed tickets with no points estimate:
https://trac.torproject.org/projects/tor/report/78
=== 041-proposed ===
Capacity Estimate
TODO: turn capacity estimates into a script or spreadsheet
?? points of proposed tickets
?? points of accepted tickets
113 days left until the 0.4.1 feature freeze, approximately 40 coding
days per person, minus ?? days for 040 bugfixes
5/7 work days in week * 220/260 non-leave week days in year * 3/5
coding days in week = 0.36 coding days per calendar day
(coding days exclude reviews, admin, travel, meetings)
List of tickets that aren't on the roadmap
#25417 -- HSFETCH support for v3 Hidden Services (needs_review)
Points needs asn or dgoulet's input, how much effort will it take us
to merge this code?
Should we try for 0.4.1?
There's something subtly wrong with a bunch of our HSv3 IPv6 code:
<-- defer deciding until asn & dgoulet input
#26992 -- Add intro point IPv6 address to service descriptors (needs_revision)
#23588 -- Write fascist_firewall_choose_address_ls() and use it in
hs_get_extend_info_from_lspecs() (needs_revision)
#23576 -- Make service_intro_point_new() take a node instead of an
extend_info (needs_revision)
I have tried to debug the issue for a few hours, but I didn't make
much progress.
I expect it will take a few days to debug: let's defer these
tickets, and pick them up if we have time later in the release
There 79 tickets below, what do we do?
Open 041-proposed tickets:
https://trac.torproject.org/projects/tor/report/75
Open 041-proposed tickets with no points estimate:
https://trac.torproject.org/projects/tor/report/76
{79 tickets here; tabling them till Brussels.}

Signal uses fixed-size, overlapping range requests to hide the exact
length of its previews:
https://signal.org/blog/i-link-therefore-i-am/
Could we use a similar technique in Tor Browser to hide sizes from
the network?
(The application and the remote site know the real size.
Everything else just sees fixed-size HTTPS.)
