In order to use this support, simply do the following (and start a reactor at some point):: from twisted.internet import inotify from twisted.python import filepath def notify(ignored, filepath, mask): """ For historical reasons, an opaque handle is passed as first parameter. This object should never be used. @param filepath: FilePath on which the event happened. @param mask: inotify event as hexadecimal masks """ print("event %s on %s" % ( ', '.join(inotify.humanReadableMask(mask)), filepath)) notifier = inotify.INotify() notifier.startReading() notifier.watch(filepath.FilePath("/some/directory"), callbacks=[notify]) notifier.watch(filepath.FilePath(b"/some/directory2"), callbacks=[notify]) Note that in the above example, a L{FilePath} which is a L{bytes} path name or L{str} path name may be used. However, no matter what type of L{FilePath} is passed to this module, internally the L{FilePath} is converted to L{bytes} according to L{sys.getfilesystemencoding}. For any L{FilePath} returned by this module, the caller is responsible for converting from a L{bytes} path name to a L{str} path name. @since: 10.1 � N)�fdesc)�FileDescriptor)�_inotify�log� � � � � � �@ � � i i i i i @ i � i i i i @l �access�modify�attribZ close_writeZ close_nowrite�openZ moved_fromZmoved_to�create�deleteZ delete_selfZ move_selfZunmountZqueue_overflowZignoredZonly_dirZ dont_followZmask_add�is_dirZone_shotc C s( g }t D ]\}}|| @ r|�|� q|S )zh Auxiliary function that converts a hexadecimal mask into a series of human readable flags. )�_FLAG_TO_HUMAN�append)�mask�s�k�v� r ��/root/rpmbuild/BUILDROOT/imh-python39-modules-3.9.7-92.el8.x86_64/opt/imh-python/lib/python3.9/site-packages/twisted/internet/inotify.py�humanReadableMaskq s r c @ s( e Zd ZdZeddfdd�Zdd� ZdS )�_Watcha� Watch object that represents a Watch point in the filesystem.

If there's no error it proceeds creating a watchpoint and adding a watchpath for inverse lookup of the file descriptor from the path. )r r �addr3 r r6 r7 )r$ r! r r" r# �wd�iwpr r r � _addWatch� s zINotify._addWatchc C s. | j �| j|� | j�|�}| j�|j� dS )a Private helper that abstracts the use of ctypes.

Note that this is a fricking hack... it's because we cannot be fast enough in adding a watch to a directory and so we basically end up getting here too late if some operations have already been going on in the subdir, we basically need to catchup. This eventually ends up meaning that we generate double events, your app must be resistant.
