Documentation

parseTree :: ByteString -> Maybe Tree Source #

renderTree :: Tree -> ByteString Source #

newtype Tree Source #

Represents the contents of a tree, which is a mapping from relative file paths to TreeEntrys.

Since: 0.1.0.0

Constructors

TreeMap (Map SafeFilePath TreeEntry)

Instances

Eq Tree Source #
Instance details Defined in Pantry.Types Methods (==) :: Tree -> Tree -> Bool # (/=) :: Tree -> Tree -> Bool #
Show Tree Source #

data TreeEntry Source #

Constructors

TreeEntry
Fields teBlob :: !BlobKey teType :: !FileType

Instances

mkSafeFilePath :: Text -> Maybe SafeFilePath Source #

pcHpackExecutable :: PantryConfig -> HpackExecutable Source #

normalizeParents :: FilePath -> Either String FilePath Source #

Like System.FilePath.normalise, however:

Only works on relative paths, absolute paths fail
Strips trailing slashes
Only works on forward slashes, even on Windows
Normalizes parent dirs foo.. get stripped
Cannot begin with a parent directory (../)
Spelled like an American, sorry

makeTarRelative Source #

Arguments

:: FilePath	base file
-> FilePath	relative part
-> Either String FilePath

Following tar file rules (Unix file paths only), make the second file relative to the first file.

getGlobalHintsFile :: HasPantryConfig env => RIO env (Path Abs File) Source #

Get the path to the global hints cache file

hpackVersion :: (HasPantryConfig env, HasLogFunc env, HasProcessContext env) => RIO env Version Source #

data Storage Source #

Represents a SQL database connection. This used to be a newtype wrapper around a connection pool. However, when investigating https://github.com/commercialhaskell/stack/issues/4471, it appeared that holding a pool resulted in overly long write locks being held on the database. As a result, we now abstract away whether a pool is used, and the default implementation in Pantry.Storage does not use a pool.

initStorage Source #

Arguments

:: HasLogFunc env
=> Text
-> Migration
-> Path Abs File	storage file
-> (Storage -> RIO env a)
-> RIO env a

withStorage_ :: Storage -> forall env a. HasLogFunc env => ReaderT SqlBackend (RIO env) a -> RIO env a Source #
