#

# Implement limited persistence.
|

#
|
||||
# Simple interface:
|
||||
# persist.save() save __main__ module on file (overwrite)
|
||||
# persist.load() load __main__ module from file (merge)
|
||||
#
|
||||
# These use the filename persist.defaultfile, initialized to 'wsrestore.py'.
|
||||
#
|
||||
# A raw interface also exists:
|
||||
# persist.writedict(dict, fp) save dictionary to open file
|
||||
# persist.readdict(dict, fp) read (merge) dictionary from open file
|
||||
#
|
||||
# Internally, the function dump() and a whole bunch of support of functions
|
||||
# traverse a graph of objects and print them in a restorable form
|
||||
# (which happens to be a Python module).
|
||||
#
|
||||
# XXX Limitations:
|
||||
# - Volatile objects are dumped as strings:
|
||||
# - open files, windows etc.
|
||||
# - Other 'obscure' objects are dumped as strings:
|
||||
# - classes, instances and methods
|
||||
# - compiled regular expressions
|
||||
# - anything else reasonably obscure (e.g., capabilities)
|
||||
# - type objects for obscure objects
|
||||
# - It's slow when there are many of lists or dictionaries

# function of any object, even if recursive)

# Module sched -- a generally useful event scheduler class
|

|

# No multi-threading is implied; you are supposed to hack that
|
||||
# yourself, or use a single instance per application.
|
||||
#
|
||||
# Each instance is parametrized with two functions, one that is
|
||||
# supposed to return the current time, one that is supposed to
|
||||
# implement a delay. You can implement fine- or course-grained
|
||||
# real-time scheduling by substituting time and sleep or millitimer
|
||||
# and millisleep from the built-in module time, or you can implement
|
||||
# simulated time by writing your own functions. This can also be
|
||||
# used to integrate scheduling with STDWIN events; the delay function
|
||||
# is allowed to modify the queue. Time can be expressed
|
||||
# as integers or floating point numbers, as long as it is consistent.
|
||||
|
||||
# Events are specified by tuples (time, priority, action, argument).
|
||||
# As in UNIX, lower priority numbers mean higher priority; in this
|
||||
# way the queue can be maintained fully sorted. Execution of the
|
||||
# event means calling the action function, passing it the argument.
|
||||
# Remember that in Python, multiple function arguments can be packed
|
||||
# in a tuple. The action function may be an instance method so it
|
