General Package Map Builders

makePackageMap :: (Paragraph -> a) -> (a -> a -> a) -> [(FilePath, Compression)] -> IO (Map ByteString a)

Source

create a map of (package name, extracted field) from a list of index files

NOTE: we could merge all the files into a single control and then run packageMap over that. We currently do it one control file at a time to avoid having all the control files loaded in memory at once. However, I am not sure that property is actually occuring anyway. So, this should be revisited.

packageMap :: (Paragraph -> a) -> (a -> a -> a) -> Control -> Map ByteString a

Source

create a map of (package name, max version) from a single control file

extractVersion :: Paragraph -> Maybe DebianVersion

Source

extract the version number from a control paragraph

trumped

Source

:: Fetcher	function for downloading package indexes
-> FilePath	cache directory to store index files in (must already exist)
-> String	binary architecture
-> [DebSource]	sources.list a
-> [DebSource]	sources.list b
-> IO (Map ByteString (DebianVersion, DebianVersion))	a map of trumped package names to (version a, version b)
compare two sources.list and find all the packages in the second that trump packages in the first see also: \|trumpedMap\|

trumpedMap

Source

:: Map ByteString DebianVersion	package map a
-> Map ByteString DebianVersion	package map b
-> Map ByteString (DebianVersion, DebianVersion)	trumped packages (version a, version b)
calculate all the trumped packages

trumpedXML :: Map ByteString (DebianVersion, DebianVersion) -> CFilter

Source

create trumped / XML element and children from a trumped Map
