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.
we had this _almost_ right, in that we were trying, but we weren't masking the
error from the user response for any error we don't intend to show. this also
adds a stack trace from any internal server errors, so that we might be able
to track them down in the future (looking at you, 'context deadline
exceeded'). in addition, this adds a new `models.APIError` interface which all
of the errors in `models` now implement, and can be caught easily / added to
easily.
the front end now does no status rewriting based on api errors, now when we
get a non-nil error we can call `handleResponse(c, err)` with it and if it's a
proper error, return it to the user with the right status code, otherwise log
a stack trace and return `internal server error`. this cleans up a lot of the
front end code.
also rewrites start task ctx deadline exceeded as timeout. with iw we had
async tasks so we could start the clock later and it didn't matter, but now
with sync tasks time out sometimes just making docker calls, and we want the
task status to show up as timed out. we may want to just catch all this above
in addition to this, but this seems like the right thing to do.
remove squishing together errors. this was weird, now we return the first
error for the purposes of using the new err interface.
removed a lot of 5xx errors that really should have been 4xx errors. changed
some of the 400 errors to 409 errors, since they are from sending in
conflicting info and not a malformed request.
removed unused errors / useless errors (many were used for logging, and didn't
provide any context. now with stack traces we don't need context as much in
the logs).
