Ganeti.Confd.Utils
Description
Implementation of the Ganeti confd utilities.
This holds a few utility functions that could be useful in both clients and servers.
- maxClockSkew :: Integer
- getClusterHmac :: IO HashKey
- parseSignedMessage :: JSON a => HashKey -> String -> Result (String, String, a)
- parseRequest :: HashKey -> String -> Integer -> Result (String, ConfdRequest)
- parseReply :: HashKey -> String -> String -> Result (String, ConfdReply)
- signMessage :: HashKey -> String -> String -> SignedMessage
- data Pointer = Pointer [String]
- readInteger :: String -> Result Int
- pointerFromString :: String -> Result Pointer
- extractValue :: JSON a => Pointer -> a -> Result JSValue
- extractJSONPath :: JSON a => String -> a -> Result JSValue
Documentation
maxClockSkew :: IntegerSource
getClusterHmac :: IO HashKeySource
Returns the HMAC key.
parseSignedMessage :: JSON a => HashKey -> String -> Result (String, String, a)Source
Parses a signed message.
parseRequest :: HashKey -> String -> Integer -> Result (String, ConfdRequest)Source
Message parsing. This can either result in a good, valid request message, or fail in the Result monad.
parseReply :: HashKey -> String -> String -> Result (String, ConfdReply)Source
Message parsing. This can either result in a good, valid reply message, or fail in the Result monad. It also checks that the salt in the message corresponds to the one that is expected
signMessage :: HashKey -> String -> String -> SignedMessageSource
Signs a message with a given key and salt.
readInteger :: String -> Result IntSource
pointerFromString :: String -> Result PointerSource
extractValue :: JSON a => Pointer -> a -> Result JSValueSource
extractJSONPath :: JSON a => String -> a -> Result JSValueSource
Extract a JSValue from an object at the position defined by the path.
The path syntax follows RCF6901. Error is returned if the path doesn't exist, Ok if the path leads to an valid value.
JSON pointer syntax according to RFC6901:
"/path/0/x" => Pointer ["path", "0", "x"]
This accesses 1 in the following JSON:
{ "path": { "0": { "x": 1 } } }
or the following:
{ "path": [{"x": 1}] }
