setTentativePending :: forall p. RepoPatch p => Repository p -> FL Prim -> IO ()Source
setTentativePending is basically unsafe. It overwrites the pending state with a new one, not related to the repository state.

tentativelyAddToPending :: forall p. RepoPatch p => Repository p -> [DarcsFlag] -> FL Prim -> IO ()Source
This fuction is unsafe because it accepts a patch that works on the tentative pending and we don't currently track the state of the tentative pending.

optimizeInventory :: RepoPatch p => Repository p -> IO ()Source

Writes out a fresh copy of the inventory that minimizes the amount of inventory that need be downloaded when people pull from the repository.

Specifically, it breaks up the inventory on the most recent tag. This speeds up most commands when run remotely, both because a smaller file needs to be transfered (only the most recent inventory). It also gives a guarantee that all the patches prior to a given tag are included in that tag, so less commutation and history traversal is needed. This latter issue can become very important in large repositories.

cleanRepository :: RepoPatch p => Repository p -> IO ()Source
getMarkedupFile :: RepoPatch p => Repository p -> PatchInfo -> FilePath -> IO MarkedUpFileSource
data PatchSet p Source
type SealedPatchSet p = Sealed (PatchSet p)Source
setScriptsExecutable :: IO ()Source
Sets scripts in or below the current directory executable. A script is any file that starts with the bytes '#!'. This is used sometimes for --set-scripts-executable, but at other times --set-scripts-executable is handled by the hunk patch case of applyFL.
getRepository :: RIO p (Repository p)Source
Similar to the ask function of the MonadReader class. This allows actions in the RIO monad to get the current repository. FIXME: Don't export this. If we don't export this it makes it harder for arbitrary IO actions to access the repository and hence our code is easier to audit.
rIO :: IO a -> RIO p aSource
This the RIO equivalent of liftIO.
