This class contains all the useful informations about the observed
event. However, the presence of each field is not guaranteed and
depends on the type of event. In effect, some fields are irrelevant
for some kind of event (for example 'cookie' is meaningless for
IN_CREATE whereas it is mandatory for IN_MOVE_TO).
The possible fields are:
- wd (int): Watch Descriptor.
- mask (int): Mask.
- maskname (str): Readable event name.
- path (str): path of the file or directory being watched.
- name (str): Basename of the file or directory against which the
event was raised in case where the watched directory
is the parent directory. None if the event was raised
on the watched item itself. This field is always provided
even if the string is ''.
- pathname (str): Concatenation of 'path' and 'name'.
- src_pathname (str): Only present for IN_MOVED_TO events and only in
the case where IN_MOVED_FROM events are watched too. Holds the
source pathname from where pathname was moved from.
- cookie (int): Cookie.
- dir (bool): True if the event was raised against a directory.

3. otherwise calls process_default

There is three kind of processing according to each event:
1. special handling (deletion from internal container, bug, ...).
2. default treatment: which is applied to the majority of events.
3. IN_ISDIR is never sent alone, he is piggybacked with a standard
event, he is not processed as the others events, instead, its
value is captured and appropriately aggregated to dst event.

STATUS: the following bug has been fixed in recent kernels (FIXME:
which version ?). Now it raises IN_DELETE_SELF instead.
Old kernels were bugged, this event raised when the watched item
were moved, so we had to update its path, but under some circumstances
it was impossible: if its parent directory and its destination
directory wasn't watched. The kernel (see include/linux/fsnotify.h)
doesn't bring us enough informations like the destination path of
moved items.
r NzëThe pathname '%s' of this watch %s has probably changed and couldn't be updated, so it cannot be trusted anymore. To fix this error move directories/files only between watched parents directories, in this case e.g. put a watch on '%s'.z

Process events objects, can be specialized via subclassing, thus its
behavior can be overriden:
Note: you should not override __init__ in your subclass instead define
a my_init() method, this method will be called automatically from the
constructor of this class with its optionals parameters.
1. Provide specialized individual methods, e.g. process_IN_DELETE for
processing a precise type of event (e.g. IN_DELETE in this case).
2. Or/and provide methods for processing events by 'family', e.g.
process_IN_CLOSE method will process both IN_CLOSE_WRITE and
IN_CLOSE_NOWRITE events (if process_IN_CLOSE_WRITE and
process_IN_CLOSE_NOWRITE aren't defined though).
3. Or/and override process_default for catching and processing all
the remaining types of events.

just have to override this method in your subclass. Then all the

transmitted as parameters to this method. Beware you MUST pass
keyword arguments though.

By default this method only reports warning messages, you can overredide
it by subclassing ProcessEvent and implement your own
process_IN_Q_OVERFLOW method. The actions you can take on receiving this
event is either to update the variable max_queued_events in order to
handle more simultaneous events or to modify your code in order to
accomplish a better filtering diminishing the number of raised events.
Because this method is defined, IN_Q_OVERFLOW will never get
transmitted as arguments to process_default calls.

want to use it in combination with an appropriate

Coalescing events. Events are usually processed by batchs, their size
depend on various factors. Thus, before processing them, events received
from inotify are aggregated in a fifo queue. If this coalescing
option is enabled events are filtered based on their unicity, only
unique events are enqueued, doublons are discarded. An event is unique
when the combination of its fields (wd, mask, cookie, name) is unique
among events of a same batch. After a batch of events is processed any
events is accepted again. By default this option is disabled, you have
to explictly call this function to turn it on.

Note that every functionality provided by this class is also provided

it is not threaded and could be easily daemonized.

Add watch(s) on the provided |path|(s) with associated |mask| flag
value and optionally with a processing |proc_fun| function and
recursive flag |rec| set to True.
All |path| components _must_ be str (i.e. unicode) objects.
If |path| is already watched it is ignored, but if it is called with
option rec=True a watch is put on each one of its not-watched
subdirectory.
@param path: Path to watch, the path can either be a file or a
directory. Also accepts a sequence (list) of paths.
@type path: string or list of strings
@param mask: Bitmask of events.
@type mask: int
@param proc_fun: Processing object.
@type proc_fun: function or ProcessEvent instance or instance of
one of its subclasses or callable object.
@param rec: Recursively add watches from path on all its
subdirectories, set to False by default (doesn't
follows symlinks in any case).
@type rec: bool
@param auto_add: Automatically add watches on newly created
directories in watched parent |path| directory.
If |auto_add| is True, IN_CREATE is ored with |mask|
when the watch is added.
@type auto_add: bool
@param do_glob: Do globbing on pathname (see standard globbing
module for more informations).

@param quiet: if False raises a WatchManagerError exception on

@param exclude_filter: predicate (boolean function), which returns
True if the current path must be excluded
from being watched. This argument has
precedence over exclude_filter passed to
the class' constructor.
@type exclude_filter: callable object
@return: dict of paths associated to watch descriptors. A wd value
is positive if the watch was added sucessfully, otherwise
the value is negative. If the path was invalid or was already
watched it is not included into this returned dictionary.

Watch a transient file, which will be created and deleted frequently
over time (e.g. pid file).
@attention: Currently under the call to this function it is not
possible to correctly watch the events triggered into the same
base directory than the directory where is located this watched
transient file. For instance it would be wrong to make these
two successive calls: wm.watch_transient_file('/var/run/foo.pid', ...)
and wm.add_watch('/var/run/', ...)
@param filename: Filename.
@type filename: string
@param mask: Bitmask of events, should contain IN_CREATE and IN_DELETE.
@type mask: int
@param proc_class: ProcessEvent (or of one of its subclass), beware of
accepting a ProcessEvent's instance as argument into
__init__, see transient_file.py example for more
details.
@type proc_class: ProcessEvent's instance or of one of its subclasses.
@return: Same as add_watch().
@rtype: Same as add_watch().

Use this function to turn on the compatibility mode. The compatibility
mode is used to improve compatibility with Pyinotify 0.7.1 (or older)
programs. The compatibility mode provides additional variables 'is_dir',
'event_name', 'EventsCodes.IN_*' and 'EventsCodes.ALL_EVENTS' as
Pyinotify 0.7.1 provided. Do not call this function from new programs!!
Especially if there are developped for Pyinotify >= 0.8.x.
