== Actions ==
* Next week (August 10th): follow up on Snowflake/Pion
incompatibility with Android 11+ and SDK >29) when Guardian project
responds and shelikhoo returns:
*
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40278
* might only affect android apps that target android>11, but
google will start requiring it soon (end of August 2023)
*
https://support.google.com/googleplay/android-developer/answer/11926878
* Issue on pion side, closed as wontfix:
https://github.com/pion/transport/issues/228
* we ought to be up to date with dependencies, as renovatebot
is connected to the snowflake repo
* meskio will cc Guardian Project on #40278 to see if they have
any insight
* shelikhoo will try to reproduce and will try the available
patches
* no news 2023-08-03

onyinyang: 2023-08-03
Last week(s):
- Implemented db
- decided against polodb and went for sled instead
https://gitlab.torproject.org/tpo/anti-censorship/lox-rs/-/merge_requests/22
- not sure if reading/writing the lox-context to json
should still be supported at all or just removed
- Implemented and tested a basic k-invites for open entry distribution
https://gitlab.torproject.org/tpo/anti-censorship/lox-rs/-/merge_requests/20
- Thought more deeply about how best to sync Lox with rdsys given
https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/168
- the rdsys API is really not designed for a distributor
like Lox that needs persistence. Even a lastPassed flag will only be
helpful for `gone` resources if Lox stores all of the resource info from
rdsys and checks it regularly. This diverges from the original intention
of rdsys, in which rdsys should be the 'arbiter of truth' for the status
of resources
- The next step is to check the rdsys API and see if the
get functionality can improve this situation. I think ideally we want a
list of all resources assigned to Lox and their current statuses that
can then be checked against something like the `lastPassed` flag each
time Lox polls rdsys.
This week:
- Continue with implementing db and synchronization between
Lox/rdsys (possibly reliant on some aspects of the former point)
- Work on adding metrics
- AFK from August 5 - 21!
(long term things were discussed at the meeting!):
https://pad.riseup.net/p/tor-ac-community-azaleas-room-keep
- brainstorming grouping strategies for Lox buckets (of
bridges) and gathering context on how types of bridges are
distributed/use in practice
Question: What makes a bridge usable for a given user, and
how can we encode that to best ensure we're getting the most appropriate
resources to people?
1. Are there some obvious grouping strategies that we
can already consider?
e.g., by pt, by bandwidth (lower bandwidth bridges
sacrificed to open-invitation buckets?), by locale (to be matched with a
requesting user's geoip or something?)
2. Does it make sense to group 3 bridges/bucket, so
trusted users have access to 3 bridges (and untrusted users have access
to 1)? More? Less?
Itchy Onion: 2023-06-08
Last week:
- fixed snowflake pipeline due to outdated Debian image
- continue working on rdsys#56 implementation. Still need to do the
following:
- finish up computing bridge distribution in Kraken
- does it have to be deterministic?
- does the disproportion have to be strictly followed
- finish writing tests
- refactor code because some functions are getting extremely long
- what to do with stencil package?
This week:
- review MRs
- continue working on rdsys#56 implementation. Still need to do the
following:
- fixed a problem with vanilla bridges not being added properly
to the database
- still working on tests
- adding a migaration patch
