== notes ==
- fixed a race on AB wrt perl
- 3.1.2 into QA
- 3.2-m2 to QA once they’re done with 3.1.2

== general ==
RP: load of perl issues over the weekend, believe to have found issue
RP: lots of qemumips issues, not sure why, perhaps a timeouts issue? (no ping
within 30 seconds)
RP: some infrastructure issues (one worker has become corrupted)

RP: curious to know what people think about 3.1.2: there is a bitbake issue
with toaster, should we release then fix or wait for fix before release?
SS: maybe we should get feedback from people using toaster
RP: the fix is simple, maybe release 3.1.2 (with release note) then fix

RP: merged re-arrangement of package manager code, this puts more of our code
into python libraries instead of bbclass files, which is the direction i
want to take going forward
RP: i need to start a conversation on oe-architecture for future directions
RP: e.g. binary package feeds, we want to capture these use-cases into the

[NB: done! see https://wiki.yoctoproject.org/wiki/Future_Directions]

RP: we also posted the current agreement on “inclusive language” as agreed
on by various groups (oe board, oe-tsc, yp-tsc)

TW: what’s the thinking behind moving code to libraries vs bbclass?
RP: pro: parsing speed con: variable dependency tracking is lost
RP: lots of python code gets written to logs etc, which slows it down
JPEW: does bitbake automatically detect variable dependencies in library code?
RP: no. maybe we just need to do the scan once?
TW: do we lose flexibility? (e.g. it’s easy to copy+paste+modify a bbclass,
will that be possible?)
RP: there will still be all the same entry points, so it should be possible
RP: i’m worried about the size of the datastore in memory and it is a

RP: i wonder why qemumips is so slow?
Randy: i think Cisco are the only ones caring about mips
RP: yes, and Comcast too i think

MM: have been wrapped up in $WORK stuff, but will be working on docs
conversion soon
RP: MH has been putting infrastructure in place and Nico is looking forward to
getting this going
MM: do we want to try to reproduce our current colours/formatting or try
something new
RP: i like what we have, the project does have an existing scheme, but we can
change if something else makes sense

TW: i do lots of builds, never seen issues, why are there so many failures on
RP: do you do oe-selftest or testsdk builds?
TW: no
RP: do you do mips builds?
TW: no
RP: so these are the areas where we see these failures, “regular” builds
are okay
SS: i don’t see issues on my builds but that’s probably because of working
these issues out on the AB
RP: infrastructure issues are low, it’s mostly race issues that come out of
the extreme load of the AB or intermittent architecture issues that are
rarely tested
