Hackage.Security.Client.Repository.Cache
Description
The files we cache from the repository
Both the Local and the Remote repositories make use of this module.
Synopsis
- data Cache = Cache {}
- getCached :: Cache -> CachedFile -> IO (Maybe (Path Absolute))
- getCachedRoot :: Cache -> IO (Path Absolute)
- getCachedIndex :: Cache -> Format f -> IO (Maybe (Path Absolute))
- clearCache :: Cache -> IO ()
- withIndex :: Cache -> (Handle -> IO a) -> IO a
- getIndexIdx :: Cache -> IO TarIndex
- cacheRemoteFile :: forall down typ f. DownloadedFile down => Cache -> down typ -> Format f -> IsCached typ -> IO ()
- lockCache :: Cache -> IO () -> IO ()
- lockCacheWithLogger :: (LogMessage -> IO ()) -> Cache -> IO () -> IO ()

getCached :: Cache -> CachedFile -> IO (Maybe (Path Absolute)) Source #
Get a cached file (if available)
getCachedRoot :: Cache -> IO (Path Absolute) Source #
Get the cached root
Calling getCachedRoot without root info available is a programmer error
and will result in an unchecked exception. See requiresBootstrap.
getCachedIndex :: Cache -> Format f -> IO (Maybe (Path Absolute)) Source #
Get the cached index (if available)
clearCache :: Cache -> IO () Source #
Delete a previously downloaded remote file
cacheRemoteFile :: forall down typ f. DownloadedFile down => Cache -> down typ -> Format f -> IsCached typ -> IO () Source #
Cache a previously downloaded remote file
lockCache :: Cache -> IO () -> IO () Source #
Lock the cache
This avoids two concurrent processes updating the cache at the same time, provided they both take the lock.
lockCacheWithLogger :: (LogMessage -> IO ()) -> Cache -> IO () -> IO () Source #
Variant of lockCache which emits LogMessages before and after
a possibly blocking file-locking system call
