* adds parity level of testing http-stream invoke
the other formats had a gamut of tests, now http-stream does too. this makes
obvious some of its behaviors. some things changed / can change now that we
don't have pipes to worry about, the main one being that when containers blow
up now the uds client will get an EOF/ECONNREFUSED instead of the pipe getting
wedged up (allowing us to get the container error easily, previously). I made
my best 50% effort to make a reasonable error for when this happens (similar
to when http/json received garbage errors), open to ideas on verbiage / policy
there.
should be pretty straightforward. one thing to notice is that
http/json/default don't return our fancy new Fn-Http-Status or Fn-Http-H
headers... it's relatively easy to go add this to fdk-go just to test this,
but for invoke I'm really not sure we care (?) and for the gateway, the output
will be identical with the old formats bypassing the header decap. if anybody
has any feelings, feel free to express them.
* fix oomer up for new error
* Adding http header stripping to agent
Adding the header stripping into the agent, this should be low enough
that all routes to fns get treated the same.
* 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.
