This implements a "detached" mechanism to get an ack from the runner
once it actually starts to run a function. In this scenario the response
returned back is just a 202 if we placed the function in a specific
time-frame. If we hit some errors or we fail to place the fn in time we
return back different errors.
* get rid of old format stuff, utils usage, fix up for fdk2.0 interface
* pure agent format removal, TODO remove format field, fix up all tests
* shitter's clogged
* fix agent tests
* start rolling through server tests
* tests compile, some failures
* remove json / content type detection on invoke/httptrigger, fix up tests
* remove hello, fixup system tests
the fucking status checker test just hangs and it's testing that it doesn't
work so the test passes but the test doesn't pass fuck life it's not worth it
* fix migration
* meh
* make dbhelper shut up about dbhelpers not being used
* move fail status at least into main thread, jfc
* fix status call to have FN_LISTENER
also turns off the stdout/stderr blocking between calls, because it's
impossible to debug without that (without syslog), now that stdout and stderr
go to the same place (either to host stderr or nowhere) and isn't used for
function output this shouldn't be a big fuss really
* remove stdin
* cleanup/remind: fixed bug where watcher would leak if container dies first
* silence system-test logs until fail, fix datastore tests
postgres does weird things with constraints when renaming tables, took the
easy way out
system-tests were loud as fuck and made you download a circleci text file of
the logs, made them only yell when they goof
* fix fdk-go dep for test image. fun
* fix swagger and remove test about format
* update all the gopkg files
* add back FN_FORMAT for fdks that assert things. pfft
* add useful error for functions that exit
this error is really confounding because containers can exit for all manner of
reason, we're just guessing that this is the most likely cause for now, and
this error message should very likely change or be removed from the client
path anyway (context.Canceled wasn't all that useful either, but anyway, I'd
been hunting for this... so found it). added a test to avoid being publicly
shamed for 1 line commits (beware...).
Largely a removal job, however many tests, particularly system level
ones relied on Routes. These have been migrated to use Fns.
* Add 410 response to swagger
* No app names in log tags
* Adding constraint in GetCall for FnID
* Adding test to check FnID is required on call
* Add fn_id to call selector
* Fix text in docker mem warning
* Correct buildConfig func name
* Test fix up
* Removing CPU setting from Agent test
CPU setting has been deprecated, but the code base is still riddled
with it. This just removes it from this layer. Really we need to
remove it from Call.
* Remove fn id check on calls
* Reintroduce fn id required on call
* Adding fnID to calls for execute test
* Correct setting of app id in middleware
* Removes root middlewares ability to redirect fun invocations
* Add over sized test check
* Removing call fn id check
* fn: runner status and docker load images
Introducing a function run for pure runner Status
calls. Previously, Status gRPC calls returned active
inflight request counts with the purpose of a simple
health checker. However this is not sufficient since
it does not show if agent or docker is healthy. With
this change, if pure runner is configured with a status
image, that image is executed through docker. The
call uses zero memory/cpu/tmpsize settings to ensure
resource tracker does not block it.
However, operators might not always have a docker
repository accessible/available for status image. Or
operators might not want the status to go over the
network. To allow such cases, and in general possibly
caching docker images, added a new environment variable
FN_DOCKER_LOAD_FILE. If this is set, fn-agent during
startup will load these images that were previously
saved with 'docker save' into docker.
