* initial invoke testing
this assures that Content-Type and Fn-Http-Status are set for an http-stream
function. it took some fixing up of the test utils code for the plumbing to
work, looking forward to deleting most stuff in fn-test-utils.go file around
each format -- had to update fdk-go to latest for http-stream support. this
only adds 1 test, since there's some machinery here, and would like to unblock
working on the http gateway simultaneously while adding a full suite of invoke
tests (this work can be parallelized)...
i added debug logs back to the debugging output. turns out this is useful, but
it can get noisy (only when things fail, hopefully).
* fix oom tests?
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
1) Early call validation and return due to cpu/mem impossible
to meet (eg. request cpu/mem larger than max-mem or max-cpu
on server) now emits HTTP Bad Request (400) instead of 503.
This case is most likely due to client/service configuration
and/or validation issue.
2) 'failed' metric is now removed. 'failed' versus 'errors'
were too confusing. 'errors' is now a catch all error case.
3) new 'canceled' counter for client side cancels.
4) 'server_busy' now covers more cases than it previously did.
