| Subversion.FileSystem.Revision |
|
|
|
|
| Description |
| An interface to functions that work on an existing
(i.e. read-only) revision in a filesystem.
|
|
| Synopsis |
|
|
|
|
| Type
|
|
| data Rev a |
Rev a is a FS monad which reads data from an existing revision
and finally returns a. See MonadFS.
Since Rev monad does no transactions,
unsafeIOToFS isn't really unsafe. You
can do any I/O actions in the monad if you wish.
|  Instances | |
|
|
| Running the monad
|
|
| withRevision :: FileSystem -> RevNum -> Rev a -> IO a |
| withRevision runs a Rev monad in an IO monad.
|
|
| Accessing revision property
|
|
| getRevisionProp :: FileSystem -> RevNum -> String -> IO (Maybe String) |
| getRevisionProp fs revNum propName returns the value of the
property named propName on revision revNum in the filesystem
fs.
|
|
| getRevisionPropList :: FileSystem -> RevNum -> IO [(String, String)] |
| getRevisionPropList fs revNum returns the entire property list
of revision revNum in filesystem fs.
|
|
| setRevisionProp |
| :: FileSystem | The transaction
| | -> RevNum | The revision
| | -> String | The property name
| | -> Maybe String | The property value
| | -> IO () | | | setRevisionProp changes, adds or deletes a property on a
revision. Note that revision properties are non-historied: you can
change them after the revision has been comitted. They are not
protected via transactions.
|
|
|
| Getting node history
|
|
| getNodeHistory |
| :: Bool | If this is true, stepping
backwards in history would cross
a copy operation. This is usually
the desired behavior.
| | -> FilePath | The path to node you want to read
history.
| | -> Rev [(RevNum, FilePath)] | A list of (revNum, nodePath):
the node was modified somehow at
revision revNum, and at that
time the node was located on
nodePath.
| getNodeHistory lazily reads the change history of given node
in a filesystem. The most recent change comes first in the
resulting list.
The revisions returned for a path will be older than or the same
age as the revision of that path in the target revision of Rev
monad. That is, if the Rev monad is running on revision X, and
the path was modified in some revisions younger than X, those
revisions younger than X will not be included for the path.
