the mqs are storing a models.Task, which was not incorporating all the fields
that are in a task.Config. I would very much like to merge these two things,
but expect to do this in a future restructuring as both are used widely and
not cordoned off properly (Config has a channel, stdin, stdout, stderr -- and
isn't just a 'config', so to speak, as Task is).
Since a task.Config is what is used to actually run a container, the result of
the aforementioned deficiency was #193 where tasks are improperly configured
and ran (namely, memory wrong).
async tasks can still not be hot, they will be reverted to default format.
would also like to fix this (also part of restructuring). I actually started
doing this, hence the changes to those files (the surface area of the change
is small and discourages improper future use, so I've left what I've done).
this will:
closes#193closes#195closes#154
removes many unused fields in models.Task, since we have not implemented
retries. priority & delay are left, even though they are not used either,
the main goal of this is to resolve#193 and both these fields are strongly
plumbed into all the mqs, so punting on those two.
prior to this patch we were allowing 256MB for every function run, just
because that was the default for the docker driver and we were not using the
memory field on any given route configuration. this fixes that, now docker
containers will get the correct memory limit passed into the container from
the route. the default is still 128.
there is also an env var now, `MEMORY_MB` that is set on each function call,
see the linked issue below for rationale.
closes#186
ran the given function code from #186, and now i only see allocations up to
32MB before the function is killed. yay.
notes:
there is no max for memory. for open source fn i'm not sure we want to
cap it, really. in the services repo we probably should add a cap before prod.
since we don't know any given fn server's ram, we can't try to make sure the
setting on any given route is something that can even be run.
remove envconfig & bytefmt
this updates the glide.yaml file to remove the unused deps, but trying to
install fresh is broken atm so i couldn't remove from vendor/, going to fix
separately (next update we just won't get these). also changed the skip dir to
be the cli dir now that its name has changed (related to brokenness).
fix how ram slots were being allocated. integer division is significantly
slower than subtraction.
