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.

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.
i s� The 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'.s

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.

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.

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.

Close inotify's file descriptor, this action will also automatically
remove (i.e. stop watching) all its associated watch descriptors.
After a call to this method the WatchManager's instance become useless

makes sense to call this method in few situations for instance if
several independant WatchManager must be instanciated or if all watches
must be removed and no other watches need to be added.

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.
Ideally |path| components should not be unicode objects. Note that
although unicode paths are accepted there are converted to byte
strings before a watch is put on that path. The encoding used for
converting the unicode object is given by sys.getfilesystemencoding().
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.

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/', ...)

mode is used to improve compatibility with Pyinotify 0.7.1 (or older)

Pyinotify 0.7.1 provided. Do not call this function from new programs!!
