From 7a53fb249f0c02762d8c13f413e24c5c250167dd Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Thu, 29 Aug 2013 18:51:22 -0400 Subject: refactor git-annex branch log filename code into central location Having one module that knows about all the filenames used on the branch allows working back from an arbitrary filename to enough information about it to implement dropping dead remotes and doing other log file compacting as part of a forget transition. --- Logs/Location.hs | 21 ++++----------------- 1 file changed, 4 insertions(+), 17 deletions(-) (limited to 'Logs/Location.hs') diff --git a/Logs/Location.hs b/Logs/Location.hs index 0f57b6663..1289af321 100644 --- a/Logs/Location.hs +++ b/Logs/Location.hs @@ -20,12 +20,11 @@ module Logs.Location ( loggedLocations, loggedKeys, loggedKeysFor, - logFile, - logFileKey ) where import Common.Annex import qualified Annex.Branch +import Logs import Logs.Presence import Annex.UUID @@ -37,19 +36,19 @@ logStatus key status = do {- Log a change in the presence of a key's value in a repository. -} logChange :: Key -> UUID -> LogStatus -> Annex () -logChange key (UUID u) s = addLog (logFile key) =<< logNow s u +logChange key (UUID u) s = addLog (locationLogFile key) =<< logNow s u logChange _ NoUUID _ = noop {- Returns a list of repository UUIDs that, according to the log, have - the value of a key. -} loggedLocations :: Key -> Annex [UUID] -loggedLocations key = map toUUID <$> (currentLog . logFile) key +loggedLocations key = map toUUID <$> (currentLog . locationLogFile) key {- Finds all keys that have location log information. - (There may be duplicate keys in the list.) -} loggedKeys :: Annex [Key] -loggedKeys = mapMaybe (logFileKey . takeFileName) <$> Annex.Branch.files +loggedKeys = mapMaybe locationLogFileKey <$> Annex.Branch.files {- Finds all keys that have location log information indicating - they are present for the specified repository. -} @@ -62,15 +61,3 @@ loggedKeysFor u = filterM isthere =<< loggedKeys us <- loggedLocations k let !there = u `elem` us return there - -{- The filename of the log file for a given key. -} -logFile :: Key -> String -logFile key = hashDirLower key ++ keyFile key ++ ".log" - -{- Converts a log filename into a key. -} -logFileKey :: FilePath -> Maybe Key -logFileKey file - | ext == ".log" = fileKey base - | otherwise = Nothing - where - (base, ext) = splitAt (length file - 4) file -- cgit v1.2.3
