From 280be11cb4706e039cf4e9f68a5ae38b0aef9340 Mon Sep 17 00:00:00 2001 From: Emilio Jesus Gallego Arias Date: Sun, 28 May 2017 00:35:57 +0200 Subject: [stm] Remove state-handling from Futures. We make Vernacentries.interp functional wrt state, and thus remove state-handling from `Future`. Now, a future needs a closure if it wants to preserve state. Consequently, `Vernacentries.interp` takes a state, and returns the new one. We don't explicitly thread the state in the STM yet, instead, we recover the state that was used before and pass it explicitly to `interp`. I have tested the commit with the files in interactive, but we aware that some new bugs may appear or old ones be made more apparent. However, I am confident that this step will improve our understanding of bugs. In some cases, we perform a bit more summary wrapping/unwrapping. This will go away in future commits; informal timings for a full make: - master: real 2m11,027s user 8m30,904s sys 1m0,000s - no_futures: real 2m8,474s user 8m34,380s sys 0m59,156s --- library/states.mli | 7 ------- 1 file changed, 7 deletions(-) (limited to 'library/states.mli') diff --git a/library/states.mli b/library/states.mli index 780a4e8dc..accd0e7ea 100644 --- a/library/states.mli +++ b/library/states.mli @@ -30,10 +30,3 @@ val replace_summary : state -> Summary.frozen -> state val with_state_protection : ('a -> 'b) -> 'a -> 'b -(** [with_state_protection_on_exception f x] applies [f] to [x] and restores the - state of the whole system as it was before applying [f] only if an - exception is raised.
