we had this _almost_ right, in that we were trying, but we weren't masking the
error from the user response for any error we don't intend to show. this also
adds a stack trace from any internal server errors, so that we might be able
to track them down in the future (looking at you, 'context deadline
exceeded'). in addition, this adds a new `models.APIError` interface which all
of the errors in `models` now implement, and can be caught easily / added to
easily.
the front end now does no status rewriting based on api errors, now when we
get a non-nil error we can call `handleResponse(c, err)` with it and if it's a
proper error, return it to the user with the right status code, otherwise log
a stack trace and return `internal server error`. this cleans up a lot of the
front end code.
also rewrites start task ctx deadline exceeded as timeout. with iw we had
async tasks so we could start the clock later and it didn't matter, but now
with sync tasks time out sometimes just making docker calls, and we want the
task status to show up as timed out. we may want to just catch all this above
in addition to this, but this seems like the right thing to do.
remove squishing together errors. this was weird, now we return the first
error for the purposes of using the new err interface.
removed a lot of 5xx errors that really should have been 4xx errors. changed
some of the 400 errors to 409 errors, since they are from sending in
conflicting info and not a malformed request.
removed unused errors / useless errors (many were used for logging, and didn't
provide any context. now with stack traces we don't need context as much in
the logs).
* add datastore validator; adapt mock and tests
* adapt bolt datastore to common validator
* adapt postgres datastore to validator
* adapt redis datastore to common validator
* Add global lru for routes with keys being the appname + path
* minor comment fixes
* remove duplicate entires from THIRD_PARTY
* Make sure that we lock and unlock on get, refresh and delete on the cache
Ensure that attempts to update route's path are properly handled
with a HTTP error. Moreover, updates swagger file to make it
explicit that routes are immutable.
