* fn: circleci and makefile adjustments
*) Moved more tasks into Makefile to allow for
parallelism and dependency checks.
*) Added cpu count in circleci make invocations
for parallelism
* fn: typo sqlite => sqlite3
* fn: removed unnecessary make pull & install
* route updated_at
* add app created at, fix some route updated_at bugs
* add app updated_at
TODO need to add tests through front end
TODO for validation we don't really want to use the validate wrapper since
it's a programmer error and not a user error, hopefully tests block this.
* add tests for timestamps to exist / change on apps&routes
* route equals at done, fix tests wit dis
* fix up the equals sugar
* add swagger
* fix rebase
* precisely allocate maps in clone
* vetted
* meh
* fix api tests
this patch has no behavior changes, changes are:
* server.Datastore() -> server.datastore
* server.MQ -> server.mq
* server.LogDB -> server.logstore
* server.Agent -> server.agent
these were at a minimum not uniform. further, it's probably better to force
configuration through initialization in `server.New` to ensure thread safety
of referencing if someone does want to modify these as well as forcing things
into our initialization path and reducing the surface area of the Server
abstraction.
* fn: adding hot container timeout and huge memory cases
*) switching TestRouteRunnerTimeout to fn-test-utils to handle
both hot and cold.
*) in server_test added content-length handling as protocol http
does not create content-length if it is not present.
* fn: add fn-test-utils image
New tester image that uses go-fdk for advanced test scenarios.
Right now, this is an enhanced 'hello/sleeper' rolled into one
that echos the received headers/env to allow writing test cases.
* Update faq.md with more Questions
I made the requested changes and added the Flow FAQ questions to the end. I tried to simplify the "How do I Upgrade the FDK" question and not sure if I helped or just mucked it up.
* Review updates to the faq document
* Fixed overview answer
* Requested updates to faq
* Flow links and wording updates
* Fix a link typo.
* fn: remove 100 msec sleep for hot containers
*) moved slot management to its own file
*) slots are now implemented with LIFO semantics, this is important since we do
not want to round robin hot containers. Idle hot containers should timeout properly.
*) each slot queue now stores a few basic stats such as avg time a call spent in a given
state and number of running/launching containers, number of waiting calls in those states.
*) first metrics in these basic stats are discarded to avoid initial docker pull/start spikes.
*) agent now records/updates slot queue state and how much time a call stayed in that state.
*) waitHotSlot() replaces the previous wait 100 msec logic where it sends a msg to
hot slot go routine launchHot() and waits for a slot
*) launchHot() is now a go routine for tracking containers in hot slots, it determines
if a new containers is needed based on slot queue stats.
* fn: for async hot requests ensure/fix content-length/type
* fn: added tests for FromModel for content type/length
* fn: restrict the content-length fix to async in FromModel()
