Instead, a -# condition object can (must) be .acquire'ed and .release'ed directly. -# This eliminates a common error in using POSIX conditions. -# -# + Because of implementation difficulties, a POSIX `signal' wakes up -# _at least_ one .wait'ing thread. Race conditions make it difficult -# to stop that. This implementation guarantees to wake up only one, -# but you probably shouldn't rely on that. -# -# PROTOCOL -# -# Condition objects are used to block threads until "some condition" is -# true. E.g., a thread may wish to wait until a producer pumps out data -# for it to consume, or a server may wish to wait until someone requests -# its services, or perhaps a whole bunch of threads want to wait until a -# preceding pass over the data is complete. Early models for conditions -# relied on some other thread figuring out when a blocked thread's -# condition was true, and made the other thread responsible both for -# waking up the blocked thread and guaranteeing that it woke up with all -# data in a correct state. This proved to be very delicate in practice, -# and gave conditions a bad name in some circles. -# -# The POSIX model addresses these problems by making a thread responsible -# for ensuring that its own state is correct when it wakes, and relies -# on a rigid protocol to make this easy; so long as you stick to the -# protocol, POSIX conditions are easy to "get right": -# -# A) The thread that's waiting for some arbitrarily-complex condition -# (ACC) to become true does: -# -# condition.acquire() -# while not (code to evaluate the ACC): -# condition.wait() -# # That blocks the thread, *and* releases the lock. When a -# # condition.signal() happens, it will wake up some thread that -# # did a .wait, *and* acquire the lock again before .wait -# # returns. -# # -# # Because the lock is acquired at this point, the state used -# # in evaluating the ACC is frozen, so it's safe to go back & -# # reevaluate the ACC. -# -# # At this point, ACC is true, and the thread has the condition -# # locked. -# # So code here can safely muck with the shared state that -# # went into evaluating the ACC -- if it wants to. -# # When done mucking with the shared state, do -# condition.release() -# -# B) Threads that are mucking with shared state that may affect the -# ACC do: -# -# condition.acquire() -# # muck with shared state -# condition.release() -# if it's possible that ACC is true now: -# condition.signal() # or .broadcast() -# -# Note: You may prefer to put the "if" clause before the release(). -# That's fine, but do note that anyone waiting on the signal will -# stay blocked until the release() is done (since acquiring the -# condition is part of what .wait() does before it returns). -# -# TRICK OF THE TRADE -# -# With simpler forms of conditions, it can be impossible to know when -# a thread that's supposed to do a .wait has actually done it. But -# because this form of condition releases a lock as _part_ of doing a -# wait, the state of that lock can be used to guarantee it. -# -# E.g., suppose thread A spawns thread B and later wants to wait for B to -# complete: -# -# In A: In B: -# -# B_done = condition() ... do work ... -# B_done.acquire() B_done.acquire(); B_done.release() -# spawn B B_done.signal() -# ... some time later ... ... and B exits ... -# B_done.wait() -# -# Because B_done was in the acquire'd state at the time B was spawned, -# B's attempt to acquire B_done can't succeed until A has done its -# B_done.wait() (which releases B_done). So B's B_done.signal() is -# guaranteed to be seen by the .wait(). Without the lock trick, B -# may signal before A .waits, and then A would wait forever. -# -# BARRIERS -# -# A barrier object is created via -# import this_module -# your_barrier = this_module.barrier(num_threads) -# -# Methods: -# .enter() -# the thread blocks until num_threads threads in all have done -# .enter(). Then the num_threads threads that .enter'ed resume, -# and the barrier resets to capture the next num_threads threads -# that .enter it. -# -# EVENTS -# -# An event object is created via -# import this_module -# your_event = this_module.event() -# -# An event has two states, `posted' and `cleared'. An event is -# created in the cleared state. -# -# Methods: -# -# .post() -# Put the event in the posted state, and resume all threads -# .wait'ing on the event (if any). -# -# .clear() -# Put the event in the cleared state. -# -# .is_posted() -# Returns 0 if the event is in the cleared state, or 1 if the event -# is in the posted state. -# -# .wait() -# If the event is in the posted state, returns immediately. -# If the event is in the cleared state, blocks the calling thread -# until the event is .post'ed by another thread. -# -# Note that an event, once posted, remains posted until explicitly -# cleared. Relative to conditions, this is both the strength & weakness -# of events. It's a strength because the .post'ing thread doesn't have to -# worry about whether the threads it's trying to communicate with have -# already done a .wait (a condition .signal is seen only by threads that -# do a .wait _prior_ to the .signal; a .signal does not persist). But -# it's a weakness because .clear'ing an event is error-prone: it's easy -# to mistakenly .clear an event before all the threads you intended to -# see the event get around to .wait'ing on it. But so long as you don't -# need to .clear an event, events are easy to use safely. -# -# SEMAPHORES -# -# A semaphore object is created via -# import this_module -# your_semaphore = this_module.semaphore(count=1) -# -# A semaphore has an integer count associated with it. The initial value -# of the count is specified by the optional argument (which defaults to -# 1) passed to the semaphore constructor. -# -# Methods: -# -# .p() -# If the semaphore's count is greater than 0, decrements the count -# by 1 and returns. -# Else if the semaphore's count is 0, blocks the calling thread -# until a subsequent .v() increases the count. When that happens, -# the count will be decremented by 1 and the calling thread resumed. -# -# .v() -# Increments the semaphore's count by 1, and wakes up a thread (if -# any) blocked by a .p(). It's an (detected) error for a .v() to -# increase the semaphore's count to a value larger than the initial -# count. -# -# MULTIPLE-READER SINGLE-WRITER LOCKS -# -# A mrsw lock is created via -# import this_module -# your_mrsw_lock = this_module.mrsw() -# -# This kind of lock is often useful with complex shared data structures. -# The object lets any number of "readers" proceed, so long as no thread -# wishes to "write". When a (one or more) thread declares its intention -# to "write" (e.g., to update a shared structure), all current readers -# are allowed to finish, and then a writer gets exclusive access; all -# other readers & writers are blocked until the current writer completes. -# Finally, if some thread is waiting to write and another is waiting to -# read, the writer takes precedence. -# -# Methods: -# -# .read_in() -# If no thread is writing or waiting to write, returns immediately. -# Else blocks until no thread is writing or waiting to write. So -# long as some thread has completed a .read_in but not a .read_out, -# writers are blocked. -# -# .read_out() -# Use sometime after a .read_in to declare that the thread is done -# reading. When all threads complete reading, a writer can proceed. -# -# .write_in() -# If no thread is writing (has completed a .write_in, but hasn't yet -# done a .write_out) or reading (similarly), returns immediately. -# Else blocks the calling thread, and threads waiting to read, until -# the current writer completes writing or all the current readers -# complete reading; if then more than one thread is waiting to -# write, one of them is allowed to proceed, but which one is not -# specified. -# -# .write_out() -# Use sometime after a .write_in to declare that the thread is done -# writing.

-======================================================== - A new turtle module for Python -======================================================== - -Turtle graphics is a popular way for introducing programming to -kids. It was part of the original Logo programming language developed -by Wally Feurzig and Seymour Papert in 1966. - -Imagine a robotic turtle starting at (0, 0) in the x-y plane. Give it -the command turtle.forward(15), and it moves (on-screen!) 15 pixels in -the direction it is facing, drawing a line as it moves. Give it the -command turtle.left(25), and it rotates in-place 25 degrees clockwise. - -By combining together these and similar commands, intricate shapes and -pictures can easily be drawn. - ------ turtle.py - -This module is an extended reimplementation of turtle.py from the -Python standard distribution up to Python 2.5. (See: http:\\www.python.org) - -It tries to keep the merits of turtle.py and to be (nearly) 100% -compatible with it. This means in the first place to enable the -learning programmer to use all the commands, classes and methods -interactively when using the module from within IDLE run with -the -n switch. - -Roughly it has the following features added: - -- Better animation of the turtle movements, especially of turning the - turtle. So the turtles can more easily be used as a visual feedback - instrument by the (beginning) programmer. - -- Different turtle shapes, gif-images as turtle shapes, user defined - and user controllable turtle shapes, among them compound - (multicolored) shapes. Turtle shapes can be stgretched and tilted, which - makes turtles zu very versatile geometrical objects. - -- Fine control over turtle movement and screen updates via delay(), - and enhanced tracer() and speed() methods. - -- Aliases for the most commonly used commands, like fd for forward etc., - following the early Logo traditions. This reduces the boring work of - typing long sequences of commands, which often occur in a natural way - when kids try to program fancy pictures on their first encounter with - turtle graphcis. - -- Turtles now have an undo()-method with configurable undo-buffer. - -- Some simple commands/methods for creating event driven programs - (mouse-, key-, timer-events). Especially useful for programming games. - -- A scrollable Canvas class. The default scrollable Canvas can be - extended interactively as needed while playing around with the turtle(s). - -- A TurtleScreen class with methods controlling background color or - background image, window and canvas size and other properties of the - TurtleScreen. - -- There is a method, setworldcoordinates(), to install a user defined - coordinate-system for the TurtleScreen. - -- The implementation uses a 2-vector class named Vec2D, derived from tuple. - This class is public, so it can be imported by the application programmer, - which makes certain types of computations very natural and compact. - -- Appearance of the TurtleScreen and the Turtles at startup/import can be - configured by means of a turtle.cfg configuration file. - The default configuration mimics the appearance of the old turtle module. - -- If configured appropriately the module reads in docstrings from a docstring - dictionary in some different language, supplied separately and replaces - the english ones by those read in. There is a utility function - write_docstringdict() to write a dictionary with the original (english) - docstrings to disc, so it can serve as a template for translations. diff --git a/Demo/turtle/about_turtledemo.txt b/Demo/turtle/about_turtledemo.txt deleted file mode 100644 index 54c25a5..0000000 --- a/Demo/turtle/about_turtledemo.txt +++ /dev/null @@ -1,13 +0,0 @@ - - -------------------------------------- - About turtleDemo.py - -------------------------------------- - - Tiny demo Viewer to view turtle graphics example scripts. - - Quickly and dirtyly assembled by Gregor Lingl. - June, 2006 - - For more information see: turtleDemo - Help - - Have fun! diff --git a/Demo/turtle/demohelp.txt b/Demo/turtle/demohelp.txt deleted file mode 100644 index 5683875..0000000 --- a/Demo/turtle/demohelp.txt +++ /dev/null @@ -1,75 +0,0 @@ - - - ---------------------------------------------- - - turtleDemo - Help - - ---------------------------------------------- - - This document has two sections: - - (1) How to use the demo viewer - (2) How to add your own demos to the demo repository - - - (1) How to use the demo viewer. - - Select a demoscript from the example menu. - The (syntax coloured) source code appears in the left - source code window.
