Synopsis

Tracing flags

Flags that control the operation of the engine.

Constructors

Fields

trace :: !Int
Tracing level (0 = quiet, 3 = very verbose).
report :: !Int
Report level: * 0 = quiet * 1 = outgone fetches, for debugging eg: timeouts * 2 = data fetch stats & errors * 3 = (same as 2, this used to enable errors) * 4 = profiling * 5 = log stack traces of dataFetch calls
caching :: !Int
Non-zero if caching is enabled. If caching is disabled, then we still do batching and de-duplication, but do not cache results.
recording :: !Int
Non-zero if recording is enabled. This allows tests to record cache calls for datasources by making uncachedRequest behave like dataFetch

ifTrace :: Monad m => Flags -> Int -> m a -> m () Source #

Runs an action if the tracing level is above the given threshold.

ifReport :: Monad m => Flags -> Int -> m a -> m () Source #

Runs an action if the report level is above the given threshold.
