* Updating Python hot HTTP sample
- using latest hotfn 0.0.5 release (made life lot easier)
* Updating to latest 0.0.6 release
What's new?
- new request data signature: context, data, loop
- supports event loop (very useful for request body handeler of coroutine type)
* Updating example with respect to recent fdk-python release
* Addressing review comments
What's new?
- better error handling
- still need to decode JSON from function because we need status code and body
- prevent request body to be a problem by deferring its close
- moving examples around: putting http and json samples into one folder
go vet caught some nifty bugs. so fixed those here, and also made it so that
we vet everything from now on since the robots seem to do a better job of
vetting than we have managed to.
also adds gofmt check to circle. could move this to the test.sh script (didn't
want a script calling a script, because $reasons) and it's nice and isolated
in its own little land as it is. side note, changed the script so it runs in
100ms instead of 3s, i think find is a lot faster than go list.
attempted some minor cleanup of various scripts
this adds `FN_` in front of env vars that we are injecting into calls, for
namespacing reasons. this will break code relying on the current variables but
if we want to do this, the chance is now really. alternatively, we could
maintain both the old and new for a short period of time to ease the
adjustment (speak now...). updated the docs, as well.
this also adds tests for the notoriously finicky configuration of the env vars
and headers when setting up a call. this won't test the container / request
for the call is actually receiving them, but it's a decent start and will yell
loudly enough upon formatting breakage.
added back FXLB_WAIT to a couple places so the lb can ride again
one thing for feedback:
headers are a bit confusing at the moment (not from this change, but that
behavior is kept here for now), we've a chance to fix them. currently, headers
in the request __are not__ prefixed with `FN_HEADER_`, i.e. 'hot'+sync containers
will receive `Content-Length` in the http request headers, yet a 'cold'
container from the same request would receive `FN_HEADER_Content-Length` in
its environment. This is additionally confusing because if this function were
hot+async, it would receive `FN_HEADER_Content-Length` in the headers, where
just changing it to sync goes back to `Content-Length`. If that was confusing,
then point made ;)
I propose to remove the `FN_HEADER_` prefix for request headers in the
environment, so that the request headers and env will match, as request
headers already are of this format (not prefixed). please lmk thoughts here
Would be fine with going back to the 'plain' vars too, then this patch will
mostly just be adding tests and changing `FN_FORMAT` to `FORMAT`. obviously,
from the examples, it's a bit ingrained now. anyway, entirely up to y'all.
