A file path represents a location for a file-like-object and can be organized into a hierarchy; a file path can can children which are themselves file paths. A file path has a name which unique identifies it in the context of its parent (if it has one); a file path can not have two children with the same name. This name is referred to as the file path's "base name". A series of such names can be used to locate nested children of a file path; such a series is referred to as the child's "path", relative to the parent. In this case, each name in the path is referred to as a "path segment"; the child's base name is the segment in the path. When representing a file path as a string, a "path separator" is used to delimit the path segments within the string. For a file system path, that would be C{os.sep}. Note that the values of child names may be restricted. For example, a file system path will not allow the use of the path separator in a name, and certain names (e.g. C{"."} and C{".."}) may be reserved or have special meanings. @since: 12.1 z3The path separator to use in string representationsc C s dS )a� Obtain a direct child of this file path.

Instantiate me with a pathname (for example, FilePath('/home/myuser/public_html')) and I will attempt to only provide access to files which reside inside that path. I may be a path to a file, a directory, or a file which does not exist. The correct way to use me is to instantiate me, and then do ALL filesystem access through me. In other words, do not import the 'os' module; if you need to open a file, call my 'open' method. If you need to list a directory, call my 'path' method. Even if you pass me a relative path, I will convert that to an absolute path internally. The type of C{path} when instantiating decides the mode of the L{FilePath}. That is, C{FilePath(b"/")} will return a L{bytes} mode L{FilePath}, and C{FilePath(u"/")} will return a L{unicode} mode L{FilePath}. C{FilePath("/")} will return a L{bytes} mode L{FilePath} on Python 2, and a L{unicode} mode L{FilePath} on Python 3. Methods that return a new L{FilePath} use the type of the given subpath to decide its mode. For example, C{FilePath(b"/").child(u"tmp")} will return a L{unicode} mode L{FilePath}. @type alwaysCreate: L{bool} @ivar alwaysCreate: When opening this file, only succeed if the file does not already exist. @ivar path: The path from which 'downward' traversal is permitted.

On UNIX-like platforms, this method does its best to ensure that by the time this method returns, either the old contents I{or} the new contents of the file will be present at this path for subsequent readers regardless of premature device removal, program crash, or power loss, making the following assumptions: - your filesystem is journaled (i.e. your filesystem will not I{itself} lose data due to power loss) - your filesystem's C{rename()} is atomic - your filesystem will not discard new data while preserving new metadata (see U{http://mjg59.livejournal.com/108257.html} for more detail) On most versions of Windows there is no atomic C{rename()} (see U{http://bit.ly/win32-overwrite} for more information), so this method is slightly less helpful. There is a small window where the file at this path may be deleted before the new file is moved to replace it: however, the new file will be fully written and flushed beforehand so in the unlikely event that there is a crash at that point, it should be possible for the user to manually recover the new version of their data. In the future, Twisted will support atomic file moves on those versions of Windows which I{do} support them: see U{Twisted ticket 3004<http://twistedmatrix.com/trac/ticket/3004>}. This method should be safe for use by multiple concurrent processes, but note that it is not easy to predict which process's contents will ultimately end up on disk if they invoke this method at close to the same time. @param content: The desired contents of the file at this path. @type content: L{bytes} @param ext: An extension to append to the temporary filename used to store the bytes while they are being written.

If self doesn't exist, an OSError is raised. If self is a directory, this method copies its children (but not itself) recursively to destination - if destination does not exist as a directory, this method creates it. If destination is a file, an IOError will be raised. If self is a file, this method copies it to destination. If destination is a file, this method overwrites it. If destination is a directory, an IOError will be raised. If self is a link (and followLinks is False), self will be copied over as a new symlink with the same target as returned by os.readlink. That means that if it is absolute, both the old and new symlink will link to the same thing. If it's relative, then perhaps not (and it's also possible that this relative link will be broken). File/directory permissions and ownership will NOT be copied over. If followLinks is True, symlinks are followed so that they're treated as their targets. In other words, if self is a link, the link's target will be copied. If destination is a link, self will be copied to the destination's target (the actual destination will be destination's target). Symlinks under self (if self is a directory) will be followed and its target's children be copied recursively. If followLinks is False, symlinks will be copied over as symlinks. @param destination: the destination (a FilePath) to which self should be copied @param followLinks: whether symlinks in self should be treated as links or as their targets Nr� zNo such file or directoryz/Only copying of files and directories supported)r/ ri r� �readlinkr, r? r r� rA r3 r �copyTor@ r6 rY � _chunkSizer| �lenrR rd re r� )rP � destination� followLinksr3 Z destChildZ writefileZreadfile�chunkr* r* r- r � s$ % B zFilePath.copyToc C s� zt �| �|j�|j� W np ty� } zX|jtjkrt|�� }| �||� |� ||� | �� }| � ||� |� � n� W Y d}~nd}~0 0 | � � |� � dS )a� Move self to destination - basically renaming self to whatever destination is named.
