#
#     Sort an input file that consists of lines like this
#
#         var1=23 other=14 ditto=23 fred=2
#
#     such that each output line is sorted WRT to the number.  Order
#     of output lines does not change.  Resolve collisions using the
#     variable name.   e.g.
#
#         fred=2 other=14 ditto=23 var1=23
#
#     Lines may be up to several kilobytes in length and contain
#     zillions of variables.

# This implementation:
# - Reads stdin, writes stdout
# - Uses any amount of whitespace to separate fields
# - Allows signed numbers
# - Treats illegally formatted fields as field=0
# - Outputs the sorted fields with exactly one space between them
# - Handles blank input lines correctly

# 1)  Regular Expressions Test
#
#     Read a file of (extended per egrep) regular expressions (one per line),
#     and apply those to all files whose names are listed on the command line.
#     Basically, an 'egrep -f' simulator.  Test it with 20 "vt100" patterns
#     against a five /etc/termcap files.  Tests using more elaborate patters
#     would also be interesting.  Your code should not break if given hundreds
#     of regular expressions or binary files to scan.

# This implementation:
# - combines all patterns into a single one using ( ... | ... | ... )
# - reads patterns from stdin, scans files given as command line arguments
# - produces output in the format <file>:<lineno>:<line>
# - is only about 2.5 times as slow as egrep (though I couldn't run
#   Tom's test -- this system, a vanilla SGI, only has /etc/terminfo)

If you're really into benchmarks, I'd love it if someone were to code up
the following problems in tcl, python, and scheme (and whatever else you'd
like).  Separate versions (one optimized for speed, one for beauty :-) are
ok.  Post your code so we can time it on our own systems.

0)  Factorial Test  (numerics and function calls)

        (we did this already)

1)  Regular Expressions Test

    Read a file of (extended per egrep) regular expressions (one per line), 
    and apply those to all files whose names are listed on the command line.
    Basically, an 'egrep -f' simulator.  Test it with 20 "vt100" patterns
    against a five /etc/termcap files.  Tests using more elaborate patters
    would also be interesting.  Your code should not break if given hundreds
    of regular expressions or binary files to scan.  

2)  Sorting Test

    Sort an input file that consists of lines like this

        var1=23 other=14 ditto=23 fred=2

    such that each output line is sorted WRT to the number.  Order
    of output lines does not change.  Resolve collisions using the
    variable name.   e.g.

        fred=2 other=14 ditto=23 var1=23 

    Lines may be up to several kilobytes in length and contain
    zillions of variables.

3)  System Test

    Given a list of directories, report any bogus symbolic links contained
    anywhere in those subtrees.  A bogus symbolic link is one that cannot
    be resolved because it points to a nonexistent or otherwise
    unresolvable file.  Do *not* use an external find executable.
    Directories may be very very deep.  Print a warning immediately if the
    system you're running on doesn't support symbolic links.


I'll post perl solutions if people post the others.

parser/READMEnu�[���These files are from the large example of using the `parser' module.  Refer
to the Python Library Reference for more information.

It also contains examples for the AST parser.

Files:
------

    FILES        -- list of files associated with the parser module.

    README       -- this file.

    docstring.py -- sample source file containing only a module docstring.

    example.py   -- module that uses the `parser' module to extract
                    information from the parse tree of Python source
                    code.

    simple.py    -- sample source containing a "short form" definition.

    source.py    -- sample source code used to demonstrate ability to
                    handle nested constructs easily using the functions
                    and classes in example.py.

    test_parser.py  program to put the parser module through its paces.

    test_unparse.py tests for the unparse module

    unparse.py      AST (2.7) based example to recreate source code
                    from an AST.

    pattern
        Pattern to match against, possibly containing variables.

    data
        Data to be checked and against which variables are extracted.

    vars
        Dictionary of variables which have already been found.  If not
        provided, an empty dictionary is created.

    The `pattern' value may contain variables of the form ['varname'] which
    are allowed to match anything.  The value that is matched is returned as
    part of a dictionary which maps 'varname' to the matched value.  'varname'
    is not required to be a string object, but using strings makes patterns
    and the code which uses them more readable.

    This function returns two values: a boolean indicating whether a match
    was found and a dictionary mapping variable names to their associated
    values.

Displays a 'breadth-first-tree' - in contrast
to the classical Logo tree drawing programs,
which use a depth-first-algorithm.

Uses:
(1) a tree-generator, where the drawing is
quasi the side-effect, whereas the generator
always yields None.
(2) Turtle-cloning: At each branching point
the current pen is cloned. So in the end
there are 1024 turtles.

========================================================
                       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. After an ``import turtle``, 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.right(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.

      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 colored) source code appears in the left
  source code window. IT CANNOT BE EDITED, but ONLY VIEWED!

  - Press START button to start the demo.
  - Stop execution by pressing the STOP button.
  - Clear screen by pressing the CLEAR button.
  - Restart by pressing the START button again.

  SPECIAL demos are those which run EVENTDRIVEN.
  (For example clock.py - or oldTurtleDemo.py which
  in the end expects a mouse click.):

      Press START button to start the demo.

      - Until the EVENTLOOP is entered everything works
      as in an ordinary demo script.

      - When the EVENTLOOP is entered, you control the
      application by using the mouse and/or keys (or it's
      controlled by some timer events)
      To stop it you can and must press the STOP button.

      While the EVENTLOOP is running, the examples menu is disabled.

      - Only after having pressed the STOP button, you may
      restart it or choose another example script.

   * * * * * * * *
   In some rare situations there may occur interferences/conflicts
   between events concerning the demo script and those concerning the
   demo-viewer. (They run in the same process.) Strange behaviour may be
   the consequence and in the worst case you must close and restart the
   viewer.
   * * * * * * * *


   (2) How to add your own demos to the demo repository
     IMPORTANT! When imported, the demo should not modify the system
     by calling functions in other modules, such as sys, tkinter, or
     turtle. Global variables should be initialized in main().

   - The script name must begin with tdemo_ ,
     so it must have the form tdemo_<your-script-name>.py

   - The code must contain a main() function which will
     be executed by the viewer (see provided example scripts).
     It may return a string which will be displayed in the Label below
     the source code window (when execution has finished.)
	   
   - In order to run mydemo.py by itself, such as during development,
     add the following at the end of the file:

    if __name__ == '__main__':
        main()
        mainloop()  # keep window 

    python -m turtledemo.mydemo  # will then run it

   - If the demo is EVENT DRIVEN, main must return the string
     "EVENTLOOP". This informs the demo viewer that the script is
     still running and must be stopped by the user!

     If an "EVENTLOOP" demo runs by itself, as with clock, which uses
     ontimer, or minimal_hanoi, which loops by recursion, then the
     code should catch the turtle.Terminator exception that will be
     raised when the user presses the STOP button.  (Paint is not such
     a demo; it only acts in response to mouse clicks and movements.)

"""repeat <shell-command>

This simple program repeatedly (at 1-second intervals) executes the
shell command given on the command line and displays the output (or as
much of it as fits on the screen).  It uses curses to paint each new
output on top of the old output, so that if nothing changes, the
screen doesn't change.  This is handy to watch for changes in e.g. a
directory or process listing.

To end, hit Control-C.

# Disclaimer: there's a Linux program named 'watch' that does the same
# thing.  Honestly, I didn't know of its existence when I wrote this!

# To do: add features until it has the same functionality as watch(1);

Afc@sJdZddlZddlZddlZddlZd�Ze�dS(s�repeat <shell-command>

This simple program repeatedly (at 1-second intervals) executes the
shell command given on the command line and displays the output (or as
much of it as fits on the screen).  It uses curses to paint each new
output on top of the old output, so that if nothing changes, the
screen doesn't change.  This is handy to watch for changes in e.g. a
directory or process listing.

To end, hit Control-C.

curses/READMEnu�[���This is a collection of demos and tests for the curses module. 

ncurses demos
=============

These demos are converted from the C versions in the ncurses
distribution, and were contributed by Thomas Gellekum <tg@FreeBSD.org>
I didn't strive for a `pythonic' style, but bluntly copied the
originals. I won't attempt to `beautify' the program anytime soon, but
I wouldn't mind someone else making an effort in that direction, of
course.

ncurses.py      -- currently only a panels demo
rain.py         -- raindrops keep falling on my desktop
tclock.py       -- ASCII clock, by Howard Jones
xmas.py         -- I'm dreaming of an ASCII christmas

Please submit bugfixes and new contributions to the Python bug tracker.


Other demos
===========

life.py         -- Simple game of Life
repeat.py       -- Repeatedly execute a shell command (like watch(1))

# I'm dreaming of an ascii character-based monochrome Christmas,
# Just like the ones I used to know!
# Via a full duplex communications channel,
# At 9600 bits per second,
# Even though it's kinda slow.
#
# I'm dreaming of an ascii character-based monochrome Christmas,
# With ev'ry C program I write!
# May your screen be merry and bright!
# And may all your Christmases be amber or green,
# (for reduced eyestrain and improved visibility)!
#
#
# Notes on the Python version:
# I used a couple of `try...except curses.error' to get around some functions
# returning ERR. The errors come from using wrapping functions to fill
# windows to the last character cell. The C version doesn't have this problem,
# it simply ignores any return values.

Afc@sJdZddlZddlZddlZddlZd�Ze�dS(s�repeat <shell-command>

This simple program repeatedly (at 1-second intervals) executes the
shell command given on the command line and displays the output (or as
much of it as fits on the screen).  It uses curses to paint each new
output on top of the old output, so that if nothing changes, the
screen doesn't change.  This is handy to watch for changes in e.g. a
directory or process listing.

To end, hit Control-C.

#       The way to think about this is that each radio button menu
#       controls a different variable -- clicking on one of the
#       mutually exclusive choices in a radiobutton assigns some value
#       to an application variable you provide. When you define a
#       radiobutton menu choice, you have the option of specifying the
#       name of a varaible and value to assign to that variable when
#       that choice is selected. This clever mechanism relieves you,
#       the programmer, from having to write a dumb callback that
#       probably wouldn't have done anything more than an assignment
#       anyway. The Tkinter options for this follow their Tk
#       counterparts:
#       {"variable" : my_flavor_variable, "value" : "strawberry"}
#       where my_flavor_variable is an instance of one of the
#       subclasses of Variable, provided in Tkinter.py (there is
#       StringVar(), IntVar(), DoubleVar() and BooleanVar() to choose
#       from)

iittexts�Ttk is the new Tk themed widget set. One of the widgets it includes is a tree widget, which can be configured to display multiple columns of informational data without displaying the tree itself. This is a simple way to build a listbox that has multiple columns. Clicking on the heading for a column will sort the data by that column. You can also change the width of the columns by dragging the boundary between them.tfilltxtbothtexpandtcolumnstshowtheadingstorienttverticalR)t

iittexts�Ttk is the new Tk themed widget set. One of the widgets it includes is a tree widget, which can be configured to display multiple columns of informational data without displaying the tree itself. This is a simple way to build a listbox that has multiple columns. Clicking on the heading for a column will sort the data by that column. You can also change the width of the columns by dragging the boundary between them.tfilltxtbothtexpandtcolumnstshowtheadingstorienttverticalR)t

This is a translation of plastik.tcl to python.
You will need the images used by the plastik theme to test this. The
images (and other tile themes) can be retrived by doing:

$ cvs -z3 -d:pserver:anonymous@tktable.cvs.sourceforge.net:/cvsroot/tktable \
  co tile-themes

To test this module you should do, for example:

import Tkinter
import plastik_theme

root = Tkinter.Tk()
plastik_theme.install(plastik_image_dir)
...

Where plastik_image_dir contains the path to the images directory used by
the plastik theme, something like: tile-themes/plastik/plastik

dS(ssThis demonstrates good part of the syntax accepted by theme_create.

This is a translation of plastik.tcl to python.
You will need the images used by the plastik theme to test this. The
images (and other tile themes) can be retrived by doing:

$ cvs -z3 -d:pserver:anonymous@tktable.cvs.sourceforge.net:/cvsroot/tktable   co tile-themes

To test this module you should do, for example:

import Tkinter
import plastik_theme

root = Tkinter.Tk()
plastik_theme.install(plastik_image_dir)
...

Where plastik_image_dir contains the path to the images directory used by
the plastik theme, something like: tile-themes/plastik/plastik

dS(ssThis demonstrates good part of the syntax accepted by theme_create.

This is a translation of plastik.tcl to python.
You will need the images used by the plastik theme to test this. The
images (and other tile themes) can be retrived by doing:

$ cvs -z3 -d:pserver:anonymous@tktable.cvs.sourceforge.net:/cvsroot/tktable   co tile-themes

To test this module you should do, for example:

import Tkinter
import plastik_theme

root = Tkinter.Tk()
plastik_theme.install(plastik_image_dir)
...

Where plastik_image_dir contains the path to the images directory used by
the plastik theme, something like: tile-themes/plastik/plastik

This module is comprised of three ``components'':

- an array visualizer with methods that implement basic sorting
operations (compare, swap) as well as methods for ``annotating'' the
sorting algorithm (e.g. to show the pivot element);

- a number of sorting algorithms (currently quicksort, insertion sort,
selection sort and bubble sort, as well as a randomization function),
all using the array visualizer for its basic operations and with calls
to its annotation methods;

- and a ``driver'' class which can be used as a Grail applet or as a
stand-alone application.

�Z	RS(s�Base class for composite graphical objects.

    Objects belong to a canvas, and can be moved around on the canvas.
    They also belong to at most one ``pile'' of objects, and can be
    transferred between piles (or removed from their pile).

    Objects have a canonical ``x, y'' position which is moved when the
    object is moved.  Where the object is relative to this position
    depends on the object; for simple objects, it may be their center.

    Objects have mouse sensitivity.  They can be clicked, dragged and
    double-clicked.  The behavior may actually be determined by the pile
    they are in.

    All instance attributes are public since the derived class may
    need them.

Cx�jjtkinter/guido/paint.pynu�[���""""Paint program by Dave Michell.

Subject: tkinter "paint" example
From: Dave Mitchell <davem@magnet.com>
To: python-list@cwi.nl
Date: Fri, 23 Jan 1998 12:18:05 -0500 (EST)

  Not too long ago (last week maybe?) someone posted a request
for an example of a paint program using Tkinter. Try as I might
I can't seem to find it in the archive, so i'll just post mine
here and hope that the person who requested it sees this!

  All this does is put up a canvas and draw a smooth black line
whenever you have the mouse button down, but hopefully it will
be enough to start with.. It would be easy enough to add some
options like other shapes or colors...

                                                yours,
                                                dave mitchell
                                                davem@magnet.com

    Objects belong to a canvas, and can be moved around on the canvas.
    They also belong to at most one ``pile'' of objects, and can be
    transferred between piles (or removed from their pile).

    Objects have a canonical ``x, y'' position which is moved when the
    object is moved.  Where the object is relative to this position
    depends on the object; for simple objects, it may be their center.

    Objects have mouse sensitivity.  They can be clicked, dragged and
    double-clicked.  The behavior may actually be determined by the pile
    they are in.

    All instance attributes are public since the derived class may
    need them.

"""Solitaire game, much like the one that comes with MS Windows.

Limitations:

- No cute graphical images for the playing cards faces or backs.
- No scoring or timer.
- No undo.
- No option to turn 3 cards at a time.
- No keyboard shortcuts.
- Less fancy animation when you win.
- The determination of which stack you drag to is more relaxed.

Apology:

I'm not much of a card player, so my terminology in these comments may
at times be a little unusual.  If you have suggestions, please let me

This module is comprised of three ``components'':

- an array visualizer with methods that implement basic sorting
operations (compare, swap) as well as methods for ``annotating'' the
sorting algorithm (e.g. to show the pivot element);

- a number of sorting algorithms (currently quicksort, insertion sort,
selection sort and bubble sort, as well as a randomization function),
all using the array visualizer for its basic operations and with calls
to its annotation methods;

- and a ``driver'' class which can be used as a Grail applet or as a
stand-alone application.

"""Sorting algorithms visualizer using Tkinter.

This module is comprised of three ``components'':

- an array visualizer with methods that implement basic sorting
operations (compare, swap) as well as methods for ``annotating'' the
sorting algorithm (e.g. to show the pivot element);

- a number of sorting algorithms (currently quicksort, insertion sort,
selection sort and bubble sort, as well as a randomization function),
all using the array visualizer for its basic operations and with calls
to its annotation methods;

- and a ``driver'' class which can be used as a Grail applet or as a
stand-alone application.

Limitations:

- No cute graphical images for the playing cards faces or backs.
- No scoring or timer.
- No undo.
- No option to turn 3 cards at a time.
- No keyboard shortcuts.
- Less fancy animation when you win.
- The determination of which stack you drag to is more relaxed.

Apology:

I'm not much of a card player, so my terminology in these comments may
at times be a little unusual.  If you have suggestions, please let me
know!

    A card doesn't record to which stack it belongs; only the stack
    records this (it turns out that we always know this from the
    context, and this saves a ``double update'' with potential for
    inconsistencies).

    Public methods:

    moveto(x, y) -- move the card to an absolute position
    moveby(dx, dy) -- move the card by a relative offset
    tkraise() -- raise the card to the top of its stack
    showface(), showback() -- turn the card face up or down & raise it

    Public read-only instance variables:

    (To show the card face up, the text item is placed in front of
    rect and the back is placed behind it.  To show it face down, this
    is reversed.  The card is created face down.)

�Zd�Zd�ZdZd�Zd�Zd�ZRS(s�A generic stack of cards.

    This is used as a base class for all other stacks (e.g. the deck,
    the suit stacks, and the row stacks).

    Public methods:

    add(card) -- add a card to the stack
    delete(card) -- delete a card from the stack
    showtop() -- show the top card (if any) face up
    deal() -- delete and return the top card, or None if empty

    Method that subclasses may override:

    position(card) -- move the card to its proper (x, y) position

        The default position() method places all cards at the stack's
        own (x, y) position.

    userclickhandler(), userdoubleclickhandler() -- called to do
    subclass specific things on single and double clicks

        The default user (single) click handler shows the top card
        face up.  The default user double click handler calls the user
        single click handler.

    usermovehandler(cards) -- called to complete a subpile move

        The default user move handler moves all moved cards back to
        their original position (by calling the position() method).

    Private methods:

    clickhandler(event), doubleclickhandler(event),
    motionhandler(event), releasehandler(event) -- event handlers

        The default event handlers turn the top card of the stack with
        its face up on a (single or double) click, and also support
        moving a subpile around.

    startmoving(event) -- begin a move operation
    finishmoving() -- finish a move operation

        the game object to find other stacks).

�Z	RS(s�Base class for composite graphical objects.

    Objects belong to a canvas, and can be moved around on the canvas.
    They also belong to at most one ``pile'' of objects, and can be
    transferred between piles (or removed from their pile).

    Objects have a canonical ``x, y'' position which is moved when the
    object is moved.  Where the object is relative to this position
    depends on the object; for simple objects, it may be their center.

    Objects have mouse sensitivity.  They can be clicked, dragged and
    double-clicked.  The behavior may actually be determined by the pile
    they are in.

    All instance attributes are public since the derived class may
    need them.

dkr\e�nd	S(sA"Paint program by Dave Michell.

Subject: tkinter "paint" example
From: Dave Mitchell <davem@magnet.com>
To: python-list@cwi.nl
Date: Fri, 23 Jan 1998 12:18:05 -0500 (EST)

  Not too long ago (last week maybe?) someone posted a request
for an example of a paint program using Tkinter. Try as I might
I can't seem to find it in the archive, so i'll just post mine
here and hope that the person who requested it sees this!

  All this does is put up a canvas and draw a smooth black line
whenever you have the mouse button down, but hopefully it will
be enough to start with.. It would be easy enough to add some
options like other shapes or colors...

                                                yours,
                                                dave mitchell

Subject: tkinter "paint" example
From: Dave Mitchell <davem@magnet.com>
To: python-list@cwi.nl
Date: Fri, 23 Jan 1998 12:18:05 -0500 (EST)

  Not too long ago (last week maybe?) someone posted a request
for an example of a paint program using Tkinter. Try as I might
I can't seem to find it in the archive, so i'll just post mine
here and hope that the person who requested it sees this!

  All this does is put up a canvas and draw a smooth black line
whenever you have the mouse button down, but hopefully it will

Limitations:

- No cute graphical images for the playing cards faces or backs.
- No scoring or timer.
- No undo.
- No option to turn 3 cards at a time.
- No keyboard shortcuts.
- Less fancy animation when you win.
- The determination of which stack you drag to is more relaxed.

Apology:

I'm not much of a card player, so my terminology in these comments may
at times be a little unusual.  If you have suggestions, please let me
know!

    A card doesn't record to which stack it belongs; only the stack
    records this (it turns out that we always know this from the
    context, and this saves a ``double update'' with potential for
    inconsistencies).

    Public methods:

    moveto(x, y) -- move the card to an absolute position
    moveby(dx, dy) -- move the card by a relative offset
    tkraise() -- raise the card to the top of its stack
    showface(), showback() -- turn the card face up or down & raise it

    Public read-only instance variables:

�Zd�Zd�ZdZd�Zd�Zd�ZRS(s�A generic stack of cards.

    This is used as a base class for all other stacks (e.g. the deck,
    the suit stacks, and the row stacks).

    Public methods:

    add(card) -- add a card to the stack
    delete(card) -- delete a card from the stack
    showtop() -- show the top card (if any) face up
    deal() -- delete and return the top card, or None if empty

    Method that subclasses may override:

    position(card) -- move the card to its proper (x, y) position

        The default position() method places all cards at the stack's
        own (x, y) position.

    userclickhandler(), userdoubleclickhandler() -- called to do
    subclass specific things on single and double clicks

        The default user (single) click handler shows the top card
        face up.  The default user double click handler calls the user
        single click handler.

    usermovehandler(cards) -- called to complete a subpile move

        The default user move handler moves all moved cards back to
        their original position (by calling the position() method).

    Private methods:

    clickhandler(event), doubleclickhandler(event),
    motionhandler(event), releasehandler(event) -- event handlers

        The default event handlers turn the top card of the stack with
        its face up on a (single or double) click, and also support
        moving a subpile around.

    startmoving(event) -- begin a move operation
    finishmoving() -- finish a move operation

^		PKb1�Z�D���READMEnu�[���This directory contains various demonstrations of what you can do with
Python.  They were all written by me except where explicitly stated
otherwise -- in general, demos contributed by others ends up in the
../Contrib directory, unless I think they're of utmost general
importance (like Matt Conway's Tk demos).

A fair number of utilities that are useful when while developing
Python code can be found in the ../Tools directory -- some of these
can also be considered good examples of how to write Python code.

Finally, in order to save disk space and net bandwidth, not all
subdirectories listed here are distributed.  They are listed just
in case I change my mind about them.


cgi             CGI examples (see also ../Tools/faqwiz/.)

classes		Some examples of how to use classes.

comparisons	A set of responses to a really old language-comparison
		challenge.

curses		A set of curses demos.

embed		An example of embedding Python in another application
		(see also pysvr).

imputil		Demonstration subclasses of imputil.Importer.

md5test		Test program for the optional md5 module.

metaclasses	The code from the 1.5 metaclasses paper on the web.

parser		Example using the parser module.

pdist		Old, unfinished code messing with CVS, RCS and remote
		files.

pysvr		An example of embedding Python in a threaded
		application.

rpc		A set of classes for building clients and servers for
		Sun RPC.

scripts		Some useful Python scripts that I put in my bin
		directory.  No optional built-in modules needed.

sockets		Examples for the new built-in module 'socket'.

threads		Demos that use the 'thread' module.  (Currently these
		only run on SGIs, but this may change in the future.)

tix		Demos using the Tix widget set addition to Tkinter.

tkinter		Demos using the Tk interface (including Matt Conway's
		excellent set of demos).

xml		Some XML demos.

zlib		Some demos for the zlib module (see also the standard
		library module gzip.py).

PKb1�Z����md5test/READMEnu�[���This is the Python version of the MD5 test program from the MD5
Internet Draft (Rivest and Dusse, The MD5 Message-Digest Algorithm, 10
July 1991).  The file "foo" contains the string "abc" with no trailing
newline.

When called without arguments, it acts as a filter.  When called with
"-x", it executes a self-test, and the output should literally match
the output given in the RFC.

s�Framework class for command line interfaces like CVS.

    The general command line structure is

            command [flags] subcommand [subflags] [argument] ...

    There's a class variable GlobalFlags which specifies the
    global flags options.  Subcommands are defined by defining
    methods named do_<subcommand>.  Flags for the subcommand are
    defined by defining class or instance variables named
    flags_<subcommand>.  If there's no command, method default()
    is called.  The __doc__ strings for the do_ methods are used
    for the usage message, printed after the general usage message
    which is the class variable UsageMessage.  The class variable
    PostUsageMessage is printed after all the do_ methods' __doc__
    strings.  The method's return value can be a suggested exit
    status.  [XXX Need to rewrite this to clarify it.]

    Common usage is to derive a class, instantiate it, and then call its
    run() method; by default this takes its arguments from sys.argv[1:].

s�Represent a file's status.

    Instance variables:

    file -- the filename (no slashes), None if uninitialized
    lseen -- true if the data for the local file is up to date
    eseen -- true if the data from the CVS/Entries entry is up to date
             (this implies that the entry must be written back)
    rseen -- true if the data for the remote file is up to date
    proxy -- RCSProxy instance used to contact the server, or None

    Note that lseen and rseen don't necessary mean that a local
    or remote file *exists* -- they indicate that we've checked it.
    However, eseen means that this instance corresponds to an
    entry in the CVS/Entries file.

    If lseen is true:

    lsum -- checksum of the local file, None if no local file
    lctime -- ctime of the local file, None if no local file
    lmtime -- mtime of the local file, None if no local file

    If eseen is true:

    erev -- revision, None if this is a no revision (not '0')
    enew -- true if this is an uncommitted added file
    edeleted -- true if this is an uncommitted removed file
    ectime -- ctime of last local file corresponding to erev
    emtime -- mtime of last local file corresponding to erev
    extra -- 5th string from CVS/Entries file

    If rseen is true:

    rrev -- revision of head, None if non-existent
    rsum -- checksum of that revision, Non if non-existent

    If eseen and rseen are both true:

    esum -- checksum of revision erev, None if no revision

"""RCS Proxy.

Provide a simplified interface on RCS files, locally or remotely.
The functionality is geared towards implementing some sort of
remote CVS like utility.  It is modeled after the similar module
FSProxy.

The module defines two classes:

RCSProxyLocal  -- used for local access
RCSProxyServer -- used on the server side of remote access

The corresponding client class, RCSProxyClient, is defined in module
rcsclient.

The remote classes are instantiated with an IP address and an optional
verbosity flag.

sRCS Proxy.

Provide a simplified interface on RCS files, locally or remotely.
The functionality is geared towards implementing some sort of
remote CVS like utility.  It is modeled after the similar module
FSProxy.

The module defines two classes:

RCSProxyLocal  -- used for local access
RCSProxyServer -- used on the server side of remote access

The corresponding client class, RCSProxyClient, is defined in module
rcsclient.

The remote classes are instantiated with an IP address and an optional
verbosity flag.

s�Represent a file's status.

    Instance variables:

    file -- the filename (no slashes), None if uninitialized
    lseen -- true if the data for the local file is up to date
    eseen -- true if the data from the CVS/Entries entry is up to date
             (this implies that the entry must be written back)
    rseen -- true if the data for the remote file is up to date
    proxy -- RCSProxy instance used to contact the server, or None

    Note that lseen and rseen don't necessary mean that a local
    or remote file *exists* -- they indicate that we've checked it.
    However, eseen means that this instance corresponds to an
    entry in the CVS/Entries file.

    If lseen is true:

    lsum -- checksum of the local file, None if no local file
    lctime -- ctime of the local file, None if no local file
    lmtime -- mtime of the local file, None if no local file

    If eseen is true:

    erev -- revision, None if this is a no revision (not '0')
    enew -- true if this is an uncommitted added file
    edeleted -- true if this is an uncommitted removed file
    ectime -- ctime of last local file corresponding to erev
    emtime -- mtime of last local file corresponding to erev
    extra -- 5th string from CVS/Entries file

    If rseen is true:

    rrev -- revision of head, None if non-existent
    rsum -- checksum of that revision, Non if non-existent

    If eseen and rseen are both true:

    esum -- checksum of revision erev, None if no revision

=================================================

*** See the security warning at the end of this file! ***

This directory contains various modules and classes that support
remote file system operations.

CVS stuff
---------

rcvs			Script to put in your bin directory
rcvs.py			Remote CVS client command line interface

cvslib.py		CVS admin files classes (used by rrcs)
cvslock.py		CVS locking algorithms

RCS stuff
---------

rrcs			Script to put in your bin directory
rrcs.py			Remote RCS client command line interface

rcsclient.py		Return an RCSProxyClient instance
			(has reasonable default server/port/directory)

RCSProxy.py		RCS proxy and server classes (on top of rcslib.py)

rcslib.py		Local-only RCS base class (affects stdout &
			local work files)

FSProxy stuff
-------------

sumtree.py		Old demo for FSProxy
cmptree.py		First FSProxy client (used to sync from the Mac)
FSProxy.py		Filesystem interface classes

Generic client/server stuff
---------------------------

client.py		Client class
server.py		Server class

security.py		Security mix-in class (not very secure I think)

Other generic stuff
-------------------

cmdfw.py		CommandFrameWork class
			(used by rcvs, should be used by rrcs as well)


Client/Server operation
-----------------------

The Client and Server classes implement a simple-minded RPC protocol,
using Python's pickle module to transfer arguments, return values and
exceptions with the most generality.  The Server class is instantiated
with a port number on which it should listen for requests; the Client
class is instantiated with a host name and a port number where it
should connect to.  Once a client is connected, a TCP connection is
maintained between client and server.

The Server class currently handles only one connection at a time;
however it could be rewritten to allow various modes of operations,
using multiple threads or processes or the select() system call as
desired to serve multiple clients simultaneously (when using select(),
still handling one request at a time).  This would not require
rewriting of the Client class.  It may also be possible to adapt the
code to use UDP instead of TCP, but then both classes will have to be
rewritten (and unless extensive acknowlegements and request serial
numbers are used, the server should handle duplicate requests, so its
semantics should be idempotent -- shrudder).

Even though the FSProxy and RCSProxy modules define client classes,
the client class is fully generic -- what methods it supports is
determined entirely by the server.  The server class, however, must be
derived from.  This is generally done as follows:

	from server import Server
	from client import Client

	# Define a class that performs the operations locally
	class MyClassLocal:
		def __init__(self): ...
		def _close(self): ...

	# Derive a server class using multiple inheritance
	class MyClassServer(MyClassLocal, Server):
		def __init__(self, address):
			# Must initialize MyClassLocal as well as Server
			MyClassLocal.__init__(self)
			Server.__init__(self, address)
		def _close(self):
			Server._close()
			MyClassLocal._close()

	# A dummy client class
	class MyClassClient(Client): pass

Note that because MyClassLocal isn't used in the definition of
MyClassClient, it would actually be better to place it in a separate
module so the definition of MyClassLocal isn't executed when we only
instantiate a client.

The modules client and server should probably be renamed to Client and
Server in order to match the class names.


*** Security warning: this version requires that you have a file
$HOME/.python_keyfile at the server and client side containing two
comma- separated numbers.  The security system at the moment makes no
guarantees of actuallng being secure -- however it requires that the
key file exists and contains the same numbers at both ends for this to
work.  (You can specify an alternative keyfile in $PYTHON_KEYFILE).
Have a look at the Security class in security.py for details;
basically, if the key file contains (x, y), then the security server
class chooses a random number z (the challenge) in the range
10..100000 and the client must be able to produce pow(z, x, y)
(i.e. z**x mod y).
PKb1�Z�W�sspdist/cvslock.pynu�[���"""CVS locking algorithm.

CVS locking strategy
====================

As reverse engineered from the CVS 1.3 sources (file lock.c):

- Locking is done on a per repository basis (but a process can hold
write locks for multiple directories); all lock files are placed in
the repository and have names beginning with "#cvs.".

- Before even attempting to lock, a file "#cvs.tfl.<pid>" is created
(and removed again), to test that we can write the repository.  [The
algorithm can still be fooled (1) if the repository's mode is changed
while attempting to lock; (2) if this file exists and is writable but
the directory is not.]

- While creating the actual read/write lock files (which may exist for
a long time), a "meta-lock" is held.  The meta-lock is a directory
named "#cvs.lock" in the repository.  The meta-lock is also held while
a write lock is held.

- To set a read lock:

        - acquire the meta-lock
        - create the file "#cvs.rfl.<pid>"
        - release the meta-lock

- To set a write lock:

        - acquire the meta-lock
        - check that there are no files called "#cvs.rfl.*"
                - if there are, release the meta-lock, sleep, try again
        - create the file "#cvs.wfl.<pid>"

- To release a write lock:

        - remove the file "#cvs.wfl.<pid>"
        - rmdir the meta-lock

- To release a read lock:

        - remove the file "#cvs.rfl.<pid>"


Additional notes
----------------

- A process should read-lock at most one repository at a time.

- A process may write-lock as many repositories as it wishes (to avoid
deadlocks, I presume it should always lock them top-down in the
directory hierarchy).

- A process should make sure it removes all its lock files and
directories when it crashes.

- Limitation: one user id should not be committing files into the same
repository at the same time.

    The general command line structure is

            command [flags] subcommand [subflags] [argument] ...

    There's a class variable GlobalFlags which specifies the
    global flags options.  Subcommands are defined by defining
    methods named do_<subcommand>.  Flags for the subcommand are
    defined by defining class or instance variables named
    flags_<subcommand>.  If there's no command, method default()
    is called.  The __doc__ strings for the do_ methods are used
    for the usage message, printed after the general usage message
    which is the class variable UsageMessage.  The class variable
    PostUsageMessage is printed after all the do_ methods' __doc__
    strings.  The method's return value can be a suggested exit
    status.  [XXX Need to rewrite this to clarify it.]

    An instance of this class represents a directory with rcs version
    files and (possible) corresponding work files.

    Methods provide access to most rcs operations such as
    checkin/checkout, access to the rcs metadata (revisions, logs,
    branches etc.) as well as some filesystem operations such as
    listing all rcs version files.

Provide an OS-neutral view on a file system, locally or remotely.
The functionality is geared towards implementing some sort of
rdist-like utility between a Mac and a UNIX system.

The module defines three classes:

FSProxyLocal  -- used for local access
FSProxyServer -- used on the server side of remote access
FSProxyClient -- used on the client side of remote access

The remote classes are instantiated with an IP address and an optional
verbosity flag.

CVS locking strategy
====================

As reverse engineered from the CVS 1.3 sources (file lock.c):

- Locking is done on a per repository basis (but a process can hold
write locks for multiple directories); all lock files are placed in
the repository and have names beginning with "#cvs.".

- Before even attempting to lock, a file "#cvs.tfl.<pid>" is created
(and removed again), to test that we can write the repository.  [The
algorithm can still be fooled (1) if the repository's mode is changed
while attempting to lock; (2) if this file exists and is writable but
the directory is not.]

- While creating the actual read/write lock files (which may exist for
a long time), a "meta-lock" is held.  The meta-lock is a directory
named "#cvs.lock" in the repository.  The meta-lock is also held while
a write lock is held.

- To set a read lock:

        - acquire the meta-lock
        - create the file "#cvs.rfl.<pid>"
        - release the meta-lock

- To set a write lock:

        - acquire the meta-lock
        - check that there are no files called "#cvs.rfl.*"
                - if there are, release the meta-lock, sleep, try again
        - create the file "#cvs.wfl.<pid>"

- To release a write lock:

        - remove the file "#cvs.wfl.<pid>"
        - rmdir the meta-lock

- To release a read lock:

        - remove the file "#cvs.rfl.<pid>"


Additional notes
----------------

- A process should read-lock at most one repository at a time.

- A process may write-lock as many repositories as it wishes (to avoid
deadlocks, I presume it should always lock them top-down in the
directory hierarchy).

- A process should make sure it removes all its lock files and
directories when it crashes.

- Limitation: one user id should not be committing files into the same
repository at the same time.


Turn this into Python code
--------------------------

rl = ReadLock(repository, waittime)

wl = WriteLock(repository, waittime)

    An instance of this class represents a directory with rcs version
    files and (possible) corresponding work files.

    Methods provide access to most rcs operations such as
    checkin/checkout, access to the rcs metadata (revisions, logs,
    branches etc.) as well as some filesystem operations such as
    listing all rcs version files.

    XXX BUGS / PROBLEMS

    - The instance always represents the current directory so it's not
    very useful to have more than one instance around simultaneously

"""Remote CVS -- command line interface"""

# XXX To do:
#
# Bugs:
# - if the remote file is deleted, "rcvs update" will fail
#
# Functionality:
# - cvs rm
# - descend into directories (alraedy done for update)
# - conflict resolution
# - other relevant commands?
# - branches
#
# - Finesses:
# - retain file mode's x bits
# - complain when "nothing known about filename"
# - edit log message the way CVS lets you edit it
# - cvs diff -rREVA -rREVB
# - send mail the way CVS sends it
#
# Performance:
# - cache remote checksums (for every revision ever seen!)
# - translate symbolic revisions to numeric revisions
#
# Reliability:
# - remote locking
#
# Security:
# - Authenticated RPC?

d	d�Zd�ZRS(
s�Framework class for command line interfaces like CVS.

    The general command line structure is

            command [flags] subcommand [subflags] [argument] ...

    There's a class variable GlobalFlags which specifies the
    global flags options.  Subcommands are defined by defining
    methods named do_<subcommand>.  Flags for the subcommand are
    defined by defining class or instance variables named
    flags_<subcommand>.  If there's no command, method default()
    is called.  The __doc__ strings for the do_ methods are used
    for the usage message, printed after the general usage message
    which is the class variable UsageMessage.  The class variable
    PostUsageMessage is printed after all the do_ methods' __doc__
    strings.  The method's return value can be a suggested exit
    status.  [XXX Need to rewrite this to clarify it.]

    Common usage is to derive a class, instantiate it, and then call its
    run() method; by default this takes its arguments from sys.argv[1:].

Provide an OS-neutral view on a file system, locally or remotely.
The functionality is geared towards implementing some sort of
rdist-like utility between a Mac and a UNIX system.

The module defines three classes:

FSProxyLocal  -- used for local access
FSProxyServer -- used on the server side of remote access
FSProxyClient -- used on the client side of remote access

The remote classes are instantiated with an IP address and an optional
verbosity flag.

sRCS Proxy.

Provide a simplified interface on RCS files, locally or remotely.
The functionality is geared towards implementing some sort of
remote CVS like utility.  It is modeled after the similar module
FSProxy.

The module defines two classes:

RCSProxyLocal  -- used for local access
RCSProxyServer -- used on the server side of remote access

The corresponding client class, RCSProxyClient, is defined in module
rcsclient.

The remote classes are instantiated with an IP address and an optional
verbosity flag.

Provide an OS-neutral view on a file system, locally or remotely.
The functionality is geared towards implementing some sort of
rdist-like utility between a Mac and a UNIX system.

The module defines three classes:

FSProxyLocal  -- used for local access
FSProxyServer -- used on the server side of remote access
FSProxyClient -- used on the client side of remote access

The remote classes are instantiated with an IP address and an optional
verbosity flag.

Hi,

I have implemented a new image type called "compound". It allows you
to glue together a bunch of bitmaps, images and text strings together
to form a bigger image. Then you can use this image with widgets that
support the -image option. For example, you can display a text string
together with a bitmap, at the same time, inside a TK button widget.

Hi,

I have implemented a new image type called "compound". It allows you
to glue together a bunch of bitmaps, images and text strings together
to form a bigger image. Then you can use this image with widgets that
support the -image option. For example, you can display a text string
together with a bitmap, at the same time, inside a TK button widget.

	@			PKb1�ZF���tix/README.txtnu�[���About Tix.py
-----------

Tix.py is based on an idea of Jean-Marc Lugrin (lugrin@ms.com) who wrote
pytix (another Python-Tix marriage). Tix widgets are an attractive and
useful extension to Tk. See http://tix.sourceforge.net
for more details about Tix and how to get it.

Features:
	1) It is almost complete.
	2) Tix widgets are represented by classes in Python. Sub-widgets
	   are members of the mega-widget class. For example, if a
	   particular TixWidget (e.g. ScrolledText) has an embedded widget
	   (Text in this case), it is possible to call the methods of the
	   child directly.
	3) The members of the class are created automatically. In the case
	   of widgets like ButtonBox, the members are added dynamically.


PKb1�Z��*ϰ�tix/INSTALL.txtnu�[���$Id$

Installing Tix.py
----------------

0) To use Tix.py, you need Tcl/Tk (V8.3.3), Tix (V8.1.1) and Python (V2.1.1).
   Tix.py has been written and tested on an Intel Pentium running RH Linux 5.2
   and Mandrake Linux 7.0 and Windows with the above mentioned packages.

   Older versions, e.g. Tix 4.1 and Tk 8.0, might also work.

   There is nothing OS-specific in Tix.py itself so it should work on
   any machine with Tix and Python installed. You can get Tcl and Tk
   from http://dev.scriptics.com and Tix from http://tix.sourceforge.net.

1) Build and install Tcl/Tk 8.3. Build and install Tix 8.1.
   Ensure that Tix is properly installed by running tixwish and executing
   the demo programs. Under Unix, use the --enable-shared configure option
   for all three. We recommend tcl8.3.3 for this release of Tix.py.

2a) If you have a distribution like ActiveState with a tcl subdirectory
   of $PYTHONHOME, which contains the directories tcl8.3 and tk8.3,
   make a directory tix8.1 as well. Recursively copy the files from
   <tix>/library to $PYTHONHOME/lib/tix8.1, and copy the dynamic library
   (tix8183.dll or libtix8.1.8.3.so) to the same place as the tcl dynamic
   libraries  ($PYTHONHOME/Dlls or lib/python-2.1/lib-dynload). In this
   case you are all installed, and you can skip to the end.

2b) Modify Modules/Setup.dist and setup.py to change the version of the 
   tix library from tix4.1.8.0 to tix8.1.8.3
   These modified files can be used for Tkinter with or without Tix.
   
3) The default is to build dynamically, and use the Tcl 'package require'.
   To build statically, modify the Modules/Setup file to link in the Tix 
   library according to the comments in the file. On Linux this looks like:

# *** Always uncomment this (leave the leading underscore in!):
_tkinter _tkinter.c tkappinit.c -DWITH_APPINIT \
# *** Uncomment and edit to reflect where your Tcl/Tk libraries are:
	-L/usr/local/lib \
# *** Uncomment and edit to reflect where your Tcl/Tk headers are:
	-I/usr/local/include \
# *** Uncomment and edit to reflect where your X11 header files are:
	-I/usr/X11R6/include \
# *** Or uncomment this for Solaris:
#	-I/usr/openwin/include \
# *** Uncomment and edit for BLT extension only:
#	-DWITH_BLT -I/usr/local/blt/blt8.0-unoff/include -lBLT8.0 \
# *** Uncomment and edit for PIL (TkImaging) extension only:
#     (See http://www.pythonware.com/products/pil/ for more info)
#	-DWITH_PIL -I../Extensions/Imaging/libImaging  tkImaging.c \
# *** Uncomment and edit for TOGL extension only:
#	-DWITH_TOGL togl.c \
# *** Uncomment and edit for Tix extension only:
	-DWITH_TIX -ltix8.1.8.3 \
# *** Uncomment and edit to reflect your Tcl/Tk versions:
	-ltk8.3 -ltcl8.3 \
# *** Uncomment and edit to reflect where your X11 libraries are:
	-L/usr/X11R6/lib \
# *** Or uncomment this for Solaris:
#	-L/usr/openwin/lib \
# *** Uncomment these for TOGL extension only:
#	-lGL -lGLU -lXext -lXmu \
# *** Uncomment for AIX:
#	-lld \
# *** Always uncomment this; X11 libraries to link with:
	-lX11

4) Rebuild Python and reinstall.

You should now have a working Tix implementation in Python. To see if all
is as it should be, run the 'tixwidgets.py' script in the Demo/tix directory.
Under X windows, do
	/usr/local/bin/python Demo/tix/tixwidgets.py

If this does not work, you may need to tell python where to find
the Tcl, Tk and Tix library files. This is done by setting the
TCL_LIBRARY, TK_LIBRARY and TIX_LIBRARY environment variables. Try this:

	env 	TCL_LIBRARY=/usr/local/lib/tcl8.3 \
		TK_LIBRARY=/usr/local/lib/tk8.3 \
		TIX_LIBRARY=/usr/local/lib/tix8.1 \
		/usr/local/bin/python Demo/tix/tixwidgets.py


If you find any bugs or have suggestions for improvement, please report them
via http://tix.sourceforge.net

    Hi,

    I have implemented a new image type called "compound". It allows you
    to glue together a bunch of bitmaps, images and text strings together
    to form a bigger image. Then you can use this image with widgets that
    support the -image option. For example, you can display a text string string
    together with a bitmap, at the same time, inside a TK button widget.

# Tix Demonstration Program
#
# This sample program is structured in such a way so that it can be
# executed from the Tix demo program "tixwidgets.py": it must have a
# procedure called "RunSample". It should also have the "if" statment
# at the end of this file so that it can be run as a standalone
# program.

# This file demonstrates the use of the tixControl widget -- it is an
# entry widget with up/down arrow buttons. You can use the arrow buttons
# to adjust the value inside the entry widget.
#
# This example program uses three Control widgets. One lets you select
# integer values; one lets you select floating point values and the last
# one lets you select a few names.

# Tix Demonstration Program
#
# This sample program is structured in such a way so that it can be
# executed from the Tix demo program "tixwidgets.py":  it must have a
# procedure called "RunSample". It should also have the "if" statment
# at the end of this file so that it can be run as a standalone
# program using tixwish.

# This file demonstrates the use of the tixDirList widget -- you can
# use it for the user to select a directory. For example, an installation
# program can use the tixDirList widget to ask the user to select the
# installation directory for an application.

Hi,

I have implemented a new image type called "compound". It allows you
to glue together a bunch of bitmaps, images and text strings together
to form a bigger image. Then you can use this image with widgets that
support the -image option. For example, you can display a text string
together with a bitmap, at the same time, inside a TK button widget.

# Usage: pp [-a] [-c] [-d] [-e scriptline] [-F fieldsep] [-n] [-p] [file] ...
# Where the options mean the following:
#   -a            : together with -n or -p, splits each line into list F
#   -c            : check syntax only, do not execute any code
#   -d            : run the script under the debugger, pdb
#   -e scriptline : gives one line of the Python script; may be repeated
#   -F fieldsep   : sets the field separator for the -a option [not in Perl]
#   -n            : runs the script for each line of input
#   -p            : prints the line after the script has run
# When no script lines have been passed, the first file argument
# contains the script.  With -n or -p, the remaining arguments are
# read as input to the script, line by line.  If a file is '-'
# or missing, standard input is read.

# XXX To do:
# - add -i extension option (change files in place)
# - make a single loop over the files and lines (changes effect of 'break')?
# - add an option to specify the record separator
# - except for -n/-p, run directly from the file if at all possible

# Fix Python source files to use the new equality test operator, i.e.,
#       if x = y: ...
# is changed to
#       if x == y: ...
# The script correctly tokenizes the Python program to reliably
# distinguish between assignments and equality tests.
#
# Command line arguments are files or directories to be processed.
# Directories are searched recursively for files whose name looks
# like a python module.
# Symbolic links are always ignored (except as explicit directory
# arguments).  Of course, the original file is kept as a back-up
# (with a "~" attached to its name).
# It complains about binaries (files containing null bytes)
# and about files that are ostensibly not Python files: if the first
# line starts with '#!' and does not contain the string 'python'.
#
# Changes made are reported to stdout in a diff-like format.
#
# Undoubtedly you can do this using find and sed or perl, but this is
# a nice example of Python code that recurses down a directory tree
# and uses regular expressions.  Also note several subtleties like
# preserving the file's mode and avoiding to even write a temp file
# when no changes are needed for a file.
#
# NB: by changing only the function fixline() you can turn this
# into a program for a different change to Python programs...

Afc@sBdZdZddd��YZd�Zedkr>e�ndS(s�N queens problem.

The (well-known) problem is due to Niklaus Wirth.

This solution is inspired by Dijkstra (Structured Programming).  It is
a classic recursive backtracking approach.

PKb1�Z��_�66embed/READMEnu�[���This directory show how to embed the Python interpreter in your own
application.  The file demo.c shows you all that is needed in your C
code.

To build it, you may have to edit the Makefile:

1) set blddir to the directory where you built Python, if it isn't in
the source directory (../..)

2) change the variables that together define the list of libraries
(MODLIBS, LIBS, SYSLIBS) to link with, to match their definitions in
$(blddir)/Modules/Makefile

An additional test program, loop.c, is used to experiment with memory
leakage caused by repeated initialization and finalization of the
interpreter.  It can be build by saying "make loop" and tested with
"make looptest".  Command line usage is "./loop <python-command>",
e.g. "./loop 'print 2+2'" should spit out an endless number of lines
containing the number 4.

       If the third argument is true, sys.path is modified to include
       either the directory containing the script named by argv[0], or
       the current working directory.  This can be risky; if you run
       an application embedding Python in a directory controlled by
       someone else, attackers could put a Trojan-horse module in the
       directory (say, a file named os.py) that your application would

# This module demonstrates how to write your own RPC client in Python.
# When this example was written, there was no RPC compiler for
# Python. Without such a compiler, you must first create classes
# derived from Packer and Unpacker to handle the data types for the
# server you want to interface to.  You then write the client class.
# If you want to support both the TCP and the UDP version of a
# protocol, use multiple inheritance as shown below.

    This is defined as the return value of time.time() on Jan 1st,

    On a Unix system, this should always return 0.0.  On a Mac, the

rpc/READMEnu�[���This is a Python interface to Sun RPC, designed and implemented mostly
by reading the Internet RFCs about the subject.

*** NOTE: xdr.py has evolved into the standard module xdrlib.py ***

There are two library modules, xdr.py and rpc.py, and several example
clients: mountclient.py, nfsclient.py, and rnusersclient.py,
implementing the NFS Mount protocol, (part of) the NFS protocol, and
the "rnusers" protocol (used by rusers(1)), respectively.  The latter
demonstrates the use of broadcast via the Port mapper's CALLIT
procedure.

There is also a way to create servers in Python.

To test the nfs client, run it from the shell with something like this:

  python -c 'import nfsclient; nfsclient.test()' [hostname [filesystemname]]

When called without a filesystemname, it lists the filesystems at the
host; default host is the local machine.

Other clients are tested similarly.

For hostname, use e.g. wuarchive.wustl.edu or gatekeeper.dec.com (two
hosts that are known to export NFS filesystems with little restrictions).

There are now two different RPC compilers:

1) Wim Lewis rpcgen.py found on http://www.omnigroup.com/~wiml/soft/stale-index.html#python. 

2) Peter �strands rpcgen.py, which is part of "pynfs" (http://www.cendio.se/~peter/pynfs/).

s9Very painful calculation of when the Unix Epoch is.

    This is defined as the return value of time.time() on Jan 1st,
    1970, 00:00:00 GMT.

    On a Unix system, this should always return 0.0.  On a Mac, the
    calculations are needed -- and hard because of integer overflow
    and other limitations.

A class which presents the reverse of a sequence without duplicating it.
From: "Steven D. Majewski" <sdm7g@elvis.med.virginia.edu>

It works on mutable or inmutable sequences.

>>> chars = list(Rev('Hello World!'))
>>> print ''.join(chars)
!dlroW olleH

The .forw is so you can use anonymous sequences in __init__, and still
keep a reference the forward sequence. )
If you give it a non-anonymous mutable sequence, the reverse sequence
will track the updated values. ( but not reassignment! - another
good reason to use anonymous values in creating the sequence to avoid
confusion. Maybe it should be change to copy input sequence to break
the connection completely ? )

>>> nnn = range(3)
>>> rnn = Rev(nnn)
>>> for n in rnn: print n
...
2
1
0
>>> for n in range(4, 6): nnn.append(n)   # update nnn
...
>>> for n in rnn: print n     # prints reversed updated values
...
5
4
2
1
0
>>> nnn = nnn[1:-1]
>>> nnn
[1, 2, 4]
>>> for n in rnn: print n     # prints reversed values of old nnn
...
5
4
2
1
0

#
>>> WH = Rev('Hello World!')
>>> print WH.forw, WH.back
Hello World! !dlroW olleH
>>> nnn = Rev(range(1, 10))
>>> print nnn.forw
[1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> print nnn.back
[9, 8, 7, 6, 5, 4, 3, 2, 1]

>>> rrr = Rev(nnn)
>>> rrr

# ---------------

# [Now that Python has a complex data type built-in, this is not very
# useful, but it's still a nice example class]

# This module represents complex numbers as instances of the class Complex.
# A Complex instance z has two data attribues, z.re (the real part) and z.im
# (the imaginary part).  In fact, z.re and z.im can have any value -- all
# arithmetic operators work regardless of the type of z.re and z.im (as long
# as they support numerical operations).
#
# The following functions exist (Complex is actually a class):
# Complex([re [,im]) -> creates a complex number from a real and an imaginary part
# IsComplex(z) -> true iff z is a complex number (== has .re and .im attributes)
# ToComplex(z) -> a complex number equal to z; z itself if IsComplex(z) is true
#                 if z is a tuple(re, im) it will also be converted
# PolarToComplex([r [,phi [,fullcircle]]]) ->
#       the complex number z for which r == z.radius() and phi == z.angle(fullcircle)
#       (r and phi default to 0)
# exp(z) -> returns the complex exponential of z. Equivalent to pow(math.e,z).
#
# Complex numbers have the following methods:
# z.abs() -> absolute value of z
# z.radius() == z.abs()
# z.angle([fullcircle]) -> angle from positive X axis; fullcircle gives units
# z.phi([fullcircle]) == z.angle(fullcircle)
#
# These standard functions and unary operators accept complex arguments:
# abs(z)
# -z
# +z
# not z
# repr(z) == `z`
# str(z)
# hash(z) -> a combination of hash(z.re) and hash(z.im) such that if z.im is zero
#            the result equals hash(z.re)
# Note that hex(z) and oct(z) are not defined.
#
# These conversions accept complex arguments only if their imaginary part is zero:
# int(z)
# long(z)
# float(z)
#
# The following operators accept two complex numbers, or one complex number
# and one real number (int, long or float):
# z1 + z2
# z1 - z2
# z1 * z2
# z1 / z2
# pow(z1, z2)
# cmp(z1, z2)
# Note that z1 % z2 and divmod(z1, z2) are not defined,
# nor are shift and mask operations.
#
# The standard module math does not support complex numbers.
# The cmath modules should be used instead.
#
# Idea:
# add a class Polar(r, phi) and mixed-mode arithmetic which
# chooses the most appropriate type for the result:
# Complex for +,-,cmp
# Polar   for *,/,pow

PKb1�Z/� ���classes/Dates.pynu�[���# Class Date supplies date objects that support date arithmetic.
#
# Date(month,day,year) returns a Date object.  An instance prints as,
# e.g., 'Mon 16 Aug 1993'.
#
# Addition, subtraction, comparison operators, min, max, and sorting
# all work as expected for date objects:  int+date or date+int returns
# the date `int' days from `date'; date+date raises an exception;
# date-int returns the date `int' days before `date'; date2-date1 returns
# an integer, the number of days from date1 to date2; int-date raises an
# exception; date1 < date2 is true iff date1 occurs before date2 (&
# similarly for other comparisons); min(date1,date2) is the earlier of
# the two dates and max(date1,date2) the later; and date objects can be
# used as dictionary keys.
#
# Date objects support one visible method, date.weekday().  This returns
# the day of the week the date falls on, as a string.
#
# Date objects also have 4 read-only data attributes:
#   .month  in 1..12
#   .day    in 1..31
#   .year   int or long int
#   .ord    the ordinal of the date relative to an arbitrary staring point
#
# The Dates module also supplies function today(), which returns the
# current date as a date object.
#
# Those entranced by calendar trivia will be disappointed, as no attempt
# has been made to accommodate the Julian (etc) system.  On the other
# hand, at least this package knows that 2000 is a leap year but 2100
# isn't, and works fine for years with a hundred decimal digits <wink>.

PKb1�ZI��classes/Rev.pynu�[���'''
A class which presents the reverse of a sequence without duplicating it.
From: "Steven D. Majewski" <sdm7g@elvis.med.virginia.edu>

It works on mutable or inmutable sequences.

>>> chars = list(Rev('Hello World!'))
>>> print ''.join(chars)
!dlroW olleH

The .forw is so you can use anonymous sequences in __init__, and still
keep a reference the forward sequence. )
If you give it a non-anonymous mutable sequence, the reverse sequence
will track the updated values. ( but not reassignment! - another
good reason to use anonymous values in creating the sequence to avoid
confusion. Maybe it should be change to copy input sequence to break
the connection completely ? )

>>> nnn = range(3)
>>> rnn = Rev(nnn)
>>> for n in rnn: print n
...
2
1
0
>>> for n in range(4, 6): nnn.append(n)   # update nnn
...
>>> for n in rnn: print n     # prints reversed updated values
...
5

2
1

>>> nnn = nnn[1:-1]
>>> nnn
[1, 2, 4]
>>> for n in rnn: print n     # prints reversed values of old nnn

A class which presents the reverse of a sequence without duplicating it.
From: "Steven D. Majewski" <sdm7g@elvis.med.virginia.edu>

It works on mutable or inmutable sequences.

>>> chars = list(Rev('Hello World!'))
>>> print ''.join(chars)
!dlroW olleH

The .forw is so you can use anonymous sequences in __init__, and still
keep a reference the forward sequence. )
If you give it a non-anonymous mutable sequence, the reverse sequence
will track the updated values. ( but not reassignment! - another
good reason to use anonymous values in creating the sequence to avoid
confusion. Maybe it should be change to copy input sequence to break
the connection completely ? )

>>> nnn = range(3)
>>> rnn = Rev(nnn)
>>> for n in rnn: print n
...
2
1
0
>>> for n in range(4, 6): nnn.append(n)   # update nnn
...
>>> for n in rnn: print n     # prints reversed updated values
...

>>> nnn = nnn[1:-1]
>>> nnn
[1, 2, 4]
>>> for n in rnn: print n     # prints reversed values of old nnn
...

>>> WH = Rev('Hello World!')
>>> print WH.forw, WH.back
Hello World! !dlroW olleH
>>> nnn = Rev(range(1, 10))
>>> print nnn.forw
[1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> print nnn.back
[9, 8, 7, 6, 5, 4, 3, 2, 1]

>>> rrr = Rev(nnn)

For example,

class C:
    def m1(self, arg):
        require arg > 0
        return whatever
        ensure Result > arg

can be written (clumsily, I agree) as:

class C(Eiffel):
    def m1(self, arg):
        return whatever
    def m1_pre(self, arg):
        assert arg > 0
    def m1_post(self, Result, arg):
        assert Result > arg

Pre- and post-conditions for a method, being implemented as methods
themselves, are inherited independently from the method.  This gives
much of the same effect of Eiffel, where pre- and post-conditions are
inherited when a method is overridden by a derived class.  However,
when a derived class in Python needs to extend a pre- or
post-condition, it must manually merge the base class' pre- or
post-condition with that defined in the derived class', for example:

class D(C):
    def m1(self, arg):
        return arg**2
    def m1_post(self, Result, arg):
        C.m1_post(self, Result, arg)
        assert Result < 100

This gives derived classes more freedom but also more responsibility
than in Eiffel, where the compiler automatically takes care of this.

In Eiffel, pre-conditions combine using contravariance, meaning a
derived class can only make a pre-condition weaker; in Python, this is
up to the derived class.  For example, a derived class that takes away
the requirement that arg > 0 could write:

    def m1_pre(self, arg):
        pass

but one could equally write a derived class that makes a stronger
requirement:

    def m1_pre(self, arg):
        require arg > 50

It would be easy to modify the classes shown here so that pre- and
post-conditions can be disabled (separately, on a per-class basis).

A different design would have the pre- or post-condition testing
functions return true for success and false for failure.  This would
make it possible to implement automatic combination of inherited
and new pre-/post-conditions.  All this is left as an exercise to the
reader.

dkr�e�e�ndS(s`Synchronization metaclass.

This metaclass  makes it possible to declare synchronized methods.

i����NtLockcBs,eZdZd�Zdd�Zd�ZRS(s�Reentrant lock.

    This is a mutex-like object which can be acquired by the same
    thread more than once.  It keeps a reference count of the number
    of times it has been acquired by the same thread.  Each acquire()
    call must be matched by a release() call and only the last
    release() call actually releases the lock for acquisition by
    another thread.

    The implementation uses two locks internally:

    __mutex is a short term lock used to protect the instance variables
    __wait is the lock for which other threads wait

    A thread intending to acquire both locks should acquire __wait
    first.

   The implementation uses two other instance variables, protected by
   locking __mutex:

    __tid is the thread ID of the thread that currently has the lock
    __count is the number of times the current thread has acquired it

    When the lock is released, __tid is None and __count is zero.

        __mutex lock).

dkr�e�e�ndS(s`Synchronization metaclass.

This metaclass  makes it possible to declare synchronized methods.

i����NtLockcBs,eZdZd�Zdd�Zd�ZRS(s�Reentrant lock.

    This is a mutex-like object which can be acquired by the same
    thread more than once.  It keeps a reference count of the number
    of times it has been acquired by the same thread.  Each acquire()
    call must be matched by a release() call and only the last
    release() call actually releases the lock for acquisition by
    another thread.

    The implementation uses two locks internally:

    __mutex is a short term lock used to protect the instance variables
    __wait is the lock for which other threads wait

    A thread intending to acquire both locks should acquire __wait
    first.

   The implementation uses two other instance variables, protected by
   locking __mutex:

    __tid is the thread ID of the thread that currently has the lock
    __count is the number of times the current thread has acquired it

    When the lock is released, __tid is None and __count is zero.

        If the optional flag argument is false, returns immediately
        when it cannot acquire the __wait lock without blocking (it
        may still block for a little while in order to acquire the
        __mutex lock).

        The return value is only relevant when the flag argument is
        false; it is 1 if the lock is acquired, 0 if not.

metaclasses/Eiffel.pynu�[���"""Support Eiffel-style preconditions and postconditions.

For example,

class C:
    def m1(self, arg):
        require arg > 0
        return whatever
        ensure Result > arg

can be written (clumsily, I agree) as:

class C(Eiffel):
    def m1(self, arg):
        return whatever
    def m1_pre(self, arg):
        assert arg > 0
    def m1_post(self, Result, arg):
        assert Result > arg

Pre- and post-conditions for a method, being implemented as methods
themselves, are inherited independently from the method.  This gives
much of the same effect of Eiffel, where pre- and post-conditions are
inherited when a method is overridden by a derived class.  However,
when a derived class in Python needs to extend a pre- or
post-condition, it must manually merge the base class' pre- or
post-condition with that defined in the derived class', for example:

class D(C):
    def m1(self, arg):
        return arg**2
    def m1_post(self, Result, arg):
        C.m1_post(self, Result, arg)
        assert Result < 100

This gives derived classes more freedom but also more responsibility
than in Eiffel, where the compiler automatically takes care of this.

In Eiffel, pre-conditions combine using contravariance, meaning a
derived class can only make a pre-condition weaker; in Python, this is
up to the derived class.  For example, a derived class that takes away
the requirement that arg > 0 could write:

    def m1_pre(self, arg):
        pass

but one could equally write a derived class that makes a stronger
requirement:

    def m1_pre(self, arg):
        require arg > 50

It would be easy to modify the classes shown here so that pre- and
post-conditions can be disabled (separately, on a per-class basis).

A different design would have the pre- or post-condition testing
functions return true for success and false for failure.  This would
make it possible to implement automatic combination of inherited
and new pre-/post-conditions.  All this is left as an exercise to the
reader.

OK, I stand corrected. I understand that anybody's interpretation of
the meta-class concept is likely to be difficult to digest by others.

Here's another try, expressing the same thing, but using the Python
programming model, examples and, perhaps, more popular terms.

1. Classes.

   This is pure Python of today. Sorry about the tutorial, but it is
   meant to illustrate the second part, which is the one we're
   interested in and which will follow the same development scenario.
   Besides, newbies are likely to understand that the discussion is
   affordable even for them :-)

   a) Class definition

      A class is meant to define the common properties of a set of objects.
      A class is a "package" of properties. The assembly of properties
      in a class package is sometimes called a class structure (which isn't
      always appropriate).

      >>> class A:
              attr1 = "Hello"                  # an attribute of A
              def method1(self, *args): pass   # method1 of A
              def method2(self, *args): pass   # method2 of A
      >>>

      So far, we defined the structure of the class A. The class A is
      of type <class>. We can check this by asking Python: "what is A?"

      >>> A                                # What is A?
      <class __main__.A at 2023e360>

   b) Class instantiation

      Creating an object with the properties defined in the class A is
      called instantiation of the class A. After an instantiation of A, we
      obtain a new object, called an instance, which has the properties
      packaged in the class A.

      >>> a = A()                          # 'a' is the 1st instance of A 
      >>> a                                # What is 'a'? 
      <__main__.A instance at 2022b9d0>

      >>> b = A()                          # 'b' is another instance of A
      >>> b                                # What is 'b'?
      <__main__.A instance at 2022b9c0>

      The objects, 'a' and 'b', are of type <instance> and they both have
      the same properties. Note, that 'a' and 'b' are different objects.
      (their adresses differ). This is a bit hard to see, so let's ask Python:

      >>> a == b                           # Is 'a' the same object as 'b'?
      0                                    # No.

      Instance objects have one more special property, indicating the class
      they are an instance of. This property is named __class__.

      >>> a.__class__                      # What is the class of 'a'?
      <class __main__.A at 2023e360>       # 'a' is an instance of A
      >>> b.__class__                      # What is the class of 'b'?
      <class __main__.A at 2023e360>       # 'b' is an instance of A
      >>> a.__class__ == b.__class__       # Is it really the same class A?
      1                                    # Yes.

   c) Class inheritance (class composition and specialization)

      Classes can be defined in terms of other existing classes (and only
      classes! -- don't bug me on this now). Thus, we can compose property
      packages and create new ones. We reuse the property set defined
      in a class by defining a new class, which "inherits" from the former.
      In other words, a class B which inherits from the class A, inherits
      the properties defined in A, or, B inherits the structure of A.

      In the same time, at the definition of the new class B, we can enrich
      the inherited set of properties by adding new ones and/or modify some
      of the inherited properties.
      
      >>> class B(A):                          # B inherits A's properties
              attr2 = "World"                  # additional attr2
              def method2(self, arg1): pass    # method2 is redefined
              def method3(self, *args): pass   # additional method3

      >>> B                                 # What is B?
      <class __main__.B at 2023e500>
      >>> B == A                            # Is B the same class as A?
      0                                     # No.

      Classes define one special property, indicating whether a class
      inherits the properties of another class. This property is called
      __bases__ and it contains a list (a tuple) of the classes the new
      class inherits from. The classes from which a class is inheriting the
      properties are called superclasses (in Python, we call them also --
      base classes).

      >>> A.__bases__                       # Does A have any superclasses?
      ()                                    # No.
      >>> B.__bases__                       # Does B have any superclasses?
      (<class __main__.A at 2023e360>,)     # Yes. It has one superclass.
      >>> B.__bases__[0] == A               # Is it really the class A?
      1                                     # Yes, it is.

--------

   Congratulations on getting this far! This was the hard part.
   Now, let's continue with the easy one.

--------

2. Meta-classes

   You have to admit, that an anonymous group of Python wizards are
   not satisfied with the property packaging facilities presented above.
   They say, that the Real-World bugs them with problems that cannot be
   modelled successfully with classes. Or, that the way classes are
   implemented in Python and the way classes and instances behave at
   runtime isn't always appropriate for reproducing the Real-World's
   behavior in a way that satisfies them.

   Hence, what they want is the following:

      a) leave objects as they are (instances of classes)
      b) leave classes as they are (property packages and object creators)

   BUT, at the same time:

      c) consider classes as being instances of mysterious objects.
      d) label mysterious objects "meta-classes".

   Easy, eh?

   You may ask: "Why on earth do they want to do that?".
   They answer: "Poor soul... Go and see how cruel the Real-World is!".
   You - fuzzy: "OK, will do!"

   And here we go for another round of what I said in section 1 -- Classes.

   However, be warned! The features we're going to talk about aren't fully
   implemented yet, because the Real-World don't let wizards to evaluate
   precisely how cruel it is, so the features are still highly-experimental.

   a) Meta-class definition

      A meta-class is meant to define the common properties of a set of
      classes.  A meta-class is a "package" of properties. The assembly
      of properties in a meta-class package is sometimes called a meta-class
      structure (which isn't always appropriate).

      In Python, a meta-class definition would have looked like this:

      >>> metaclass M:
              attr1 = "Hello"                  # an attribute of M
              def method1(self, *args): pass   # method1 of M
              def method2(self, *args): pass   # method2 of M
      >>>

      So far, we defined the structure of the meta-class M. The meta-class
      M is of type <metaclass>. We cannot check this by asking Python, but
      if we could, it would have answered:

      >>> M                                # What is M?
      <metaclass __main__.M at 2023e4e0>

   b) Meta-class instantiation

      Creating an object with the properties defined in the meta-class M is
      called instantiation of the meta-class M. After an instantiation of M,
      we obtain a new object, called an class, but now it is called also
      a meta-instance, which has the properties packaged in the meta-class M.

      In Python, instantiating a meta-class would have looked like this:

      >>> A = M()                          # 'A' is the 1st instance of M
      >>> A                                # What is 'A'?
      <class __main__.A at 2022b9d0>

      >>> B = M()                          # 'B' is another instance of M
      >>> B                                # What is 'B'?
      <class __main__.B at 2022b9c0>

      The metaclass-instances, A and B, are of type <class> and they both
      have the same properties. Note, that A and B are different objects.
      (their adresses differ). This is a bit hard to see, but if it was
      possible to ask Python, it would have answered:

      >>> A == B                           # Is A the same class as B?
      0                                    # No.

      Class objects have one more special property, indicating the meta-class
      they are an instance of. This property is named __metaclass__.

      >>> A.__metaclass__                  # What is the meta-class of A?
      <metaclass __main__.M at 2023e4e0>   # A is an instance of M
      >>> A.__metaclass__                  # What is the meta-class of B?
      <metaclass __main__.M at 2023e4e0>   # B is an instance of M
      >>> A.__metaclass__ == B.__metaclass__  # Is it the same meta-class M?
      1                                    # Yes.

   c) Meta-class inheritance (meta-class composition and specialization)

      Meta-classes can be defined in terms of other existing meta-classes
      (and only meta-classes!). Thus, we can compose property packages and
      create new ones. We reuse the property set defined in a meta-class by
      defining a new meta-class, which "inherits" from the former.
      In other words, a meta-class N which inherits from the meta-class M,
      inherits the properties defined in M, or, N inherits the structure of M.

      In the same time, at the definition of the new meta-class N, we can
      enrich the inherited set of properties by adding new ones and/or modify
      some of the inherited properties.

      >>> metaclass N(M):                      # N inherits M's properties
              attr2 = "World"                  # additional attr2
              def method2(self, arg1): pass    # method2 is redefined
              def method3(self, *args): pass   # additional method3

      >>> N                              # What is N?
      <metaclass __main__.N at 2023e500>
      >>> N == M                         # Is N the same meta-class as M?
      0                                  # No.

      Meta-classes define one special property, indicating whether a
      meta-class inherits the properties of another meta-class. This property
      is called __metabases__ and it contains a list (a tuple) of the
      meta-classes the new meta-class inherits from. The meta-classes from
      which a meta-class is inheriting the properties are called
      super-meta-classes (in Python, we call them also -- super meta-bases).

      >>> M.__metabases__                # Does M have any supermetaclasses?
      ()                                 # No.
      >>> N.__metabases__                # Does N have any supermetaclasses?
      (<metaclass __main__.M at 2023e360>,)  # Yes. It has a supermetaclass.
      >>> N.__metabases__[0] == M        # Is it really the meta-class M?
      1                                  # Yes, it is.

   Triple congratulations on getting this far!
   Now you know everything about meta-classes and the Real-World!

<BODY BGCOLOR="FFFFFF">

<H1>Metaclasses in Python 1.5</H1>
<H2>(A.k.a. The Killer Joke :-)</H2>

<HR>

(<i>Postscript:</i> reading this essay is probably not the best way to
understand the metaclass hook described here.  See a <A
HREF="meta-vladimir.txt">message posted by Vladimir Marangozov</A>
which may give a gentler introduction to the matter.  You may also
want to search Deja News for messages with "metaclass" in the subject
posted to comp.lang.python in July and August 1998.)

<HR>

<P>In previous Python releases (and still in 1.5), there is something
called the ``Don Beaudry hook'', after its inventor and champion.
This allows C extensions to provide alternate class behavior, thereby
allowing the Python class syntax to be used to define other class-like
entities.  Don Beaudry has used this in his infamous <A
HREF="http://maigret.cog.brown.edu/pyutil/">MESS</A> package; Jim
Fulton has used it in his <A
HREF="http://www.digicool.com/releases/ExtensionClass/">Extension
Classes</A> package.  (It has also been referred to as the ``Don
Beaudry <i>hack</i>,'' but that's a misnomer.  There's nothing hackish
about it -- in fact, it is rather elegant and deep, even though
there's something dark to it.)

<P>(On first reading, you may want to skip directly to the examples in
the section "Writing Metaclasses in Python" below, unless you want
your head to explode.)

<P>

<HR>

<P>Documentation of the Don Beaudry hook has purposefully been kept
minimal, since it is a feature of incredible power, and is easily
abused.  Basically, it checks whether the <b>type of the base
class</b> is callable, and if so, it is called to create the new
class.

<P>Note the two indirection levels.  Take a simple example:

<PRE>
class B:
    pass

class C(B):
    pass
</PRE>

Take a look at the second class definition, and try to fathom ``the
type of the base class is callable.''

<P>(Types are not classes, by the way.  See questions 4.2, 4.19 and in
particular 6.22 in the <A
HREF="http://www.python.org/cgi-bin/faqw.py" >Python FAQ</A>
for more on this topic.)

<P>

<UL>

<LI>The <b>base class</b> is B; this one's easy.<P>

<LI>Since B is a class, its type is ``class''; so the <b>type of the
base class</b> is the type ``class''.  This is also known as
types.ClassType, assuming the standard module <code>types</code> has
been imported.<P>

<LI>Now is the type ``class'' <b>callable</b>?  No, because types (in
core Python) are never callable.  Classes are callable (calling a
class creates a new instance) but types aren't.<P>

</UL>

<P>So our conclusion is that in our example, the type of the base
class (of C) is not callable.  So the Don Beaudry hook does not apply,
and the default class creation mechanism is used (which is also used
when there is no base class).  In fact, the Don Beaudry hook never
applies when using only core Python, since the type of a core object
is never callable.

<P>So what do Don and Jim do in order to use Don's hook?  Write an
extension that defines at least two new Python object types.  The
first would be the type for ``class-like'' objects usable as a base
class, to trigger Don's hook.  This type must be made callable.
That's why we need a second type.  Whether an object is callable
depends on its type.  So whether a type object is callable depends on
<i>its</i> type, which is a <i>meta-type</i>.  (In core Python there
is only one meta-type, the type ``type'' (types.TypeType), which is
the type of all type objects, even itself.)  A new meta-type must
be defined that makes the type of the class-like objects callable.
(Normally, a third type would also be needed, the new ``instance''
type, but this is not an absolute requirement -- the new class type
could return an object of some existing type when invoked to create an
instance.)

<P>Still confused?  Here's a simple device due to Don himself to
explain metaclasses.  Take a simple class definition; assume B is a
special class that triggers Don's hook:

<PRE>
class C(B):
    a = 1
    b = 2
</PRE>

This can be though of as equivalent to:

<PRE>
C = type(B)('C', (B,), {'a': 1, 'b': 2})
</PRE>

If that's too dense for you, here's the same thing written out using
temporary variables:

<PRE>
creator = type(B)               # The type of the base class
name = 'C'                      # The name of the new class
bases = (B,)                    # A tuple containing the base class(es)
namespace = {'a': 1, 'b': 2}    # The namespace of the class statement
C = creator(name, bases, namespace)
</PRE>

This is analogous to what happens without the Don Beaudry hook, except
that in that case the creator function is set to the default class
creator.

<P>In either case, the creator is called with three arguments.  The
first one, <i>name</i>, is the name of the new class (as given at the
top of the class statement).  The <i>bases</i> argument is a tuple of
base classes (a singleton tuple if there's only one base class, like
the example).  Finally, <i>namespace</i> is a dictionary containing
the local variables collected during execution of the class statement.

<P>Note that the contents of the namespace dictionary is simply
whatever names were defined in the class statement.  A little-known
fact is that when Python executes a class statement, it enters a new
local namespace, and all assignments and function definitions take
place in this namespace.  Thus, after executing the following class
statement:

<PRE>
class C:
    a = 1
    def f(s): pass
</PRE>

the class namespace's contents would be {'a': 1, 'f': &lt;function f
...&gt;}.

<P>But enough already about writing Python metaclasses in C; read the
documentation of <A
HREF="http://maigret.cog.brown.edu/pyutil/">MESS</A> or <A
HREF="http://www.digicool.com/papers/ExtensionClass.html" >Extension

<H2>Writing Metaclasses in Python</H2>

<P>In Python 1.5, the requirement to write a C extension in order to
write metaclasses has been dropped (though you can still do
it, of course).  In addition to the check ``is the type of the base
class callable,'' there's a check ``does the base class have a
__class__ attribute.''  If so, it is assumed that the __class__
attribute refers to a class.

<P>Let's repeat our simple example from above:

<PRE>
class C(B):
    a = 1
    b = 2
</PRE>

Assuming B has a __class__ attribute, this translates into:

<PRE>
C = B.__class__('C', (B,), {'a': 1, 'b': 2})
</PRE>

This is exactly the same as before except that instead of type(B),
B.__class__ is invoked.  If you have read <A HREF=
"http://www.python.org/cgi-bin/faqw.py?req=show&file=faq06.022.htp"
>FAQ question 6.22</A> you will understand that while there is a big
technical difference between type(B) and B.__class__, they play the
same role at different abstraction levels.  And perhaps at some point
in the future they will really be the same thing (at which point you
would be able to derive subclasses from built-in types).

<P>At this point it may be worth mentioning that C.__class__ is the
same object as B.__class__, i.e., C's metaclass is the same as B's
metaclass.  In other words, subclassing an existing class creates a
new (meta)inststance of the base class's metaclass.

<P>Going back to the example, the class B.__class__ is instantiated,
passing its constructor the same three arguments that are passed to
the default class constructor or to an extension's metaclass:
<i>name</i>, <i>bases</i>, and <i>namespace</i>.

<P>It is easy to be confused by what exactly happens when using a
metaclass, because we lose the absolute distinction between classes
and instances: a class is an instance of a metaclass (a
``metainstance''), but technically (i.e. in the eyes of the python
runtime system), the metaclass is just a class, and the metainstance
is just an instance.  At the end of the class statement, the metaclass
whose metainstance is used as a base class is instantiated, yielding a
second metainstance (of the same metaclass).  This metainstance is
then used as a (normal, non-meta) class; instantiation of the class
means calling the metainstance, and this will return a real instance.
And what class is that an instance of?  Conceptually, it is of course
an instance of our metainstance; but in most cases the Python runtime
system will see it as an instance of a helper class used by the
metaclass to implement its (non-meta) instances...

<P>Hopefully an example will make things clearer.  Let's presume we
have a metaclass MetaClass1.  It's helper class (for non-meta
instances) is callled HelperClass1.  We now (manually) instantiate
MetaClass1 once to get an empty special base class:

<PRE>
BaseClass1 = MetaClass1("BaseClass1", (), {})
</PRE>

We can now use BaseClass1 as a base class in a class statement:

<PRE>
class MySpecialClass(BaseClass1):
    i = 1
    def f(s): pass
</PRE>

At this point, MySpecialClass is defined; it is a metainstance of
MetaClass1 just like BaseClass1, and in fact the expression
``BaseClass1.__class__ == MySpecialClass.__class__ == MetaClass1''
yields true.

<P>We are now ready to create instances of MySpecialClass.  Let's
assume that no constructor arguments are required:

<PRE>
x = MySpecialClass()
y = MySpecialClass()
print x.__class__, y.__class__
</PRE>

The print statement shows that x and y are instances of HelperClass1.
How did this happen?  MySpecialClass is an instance of MetaClass1
(``meta'' is irrelevant here); when an instance is called, its
__call__ method is invoked, and presumably the __call__ method defined
by MetaClass1 returns an instance of HelperClass1.

<P>Now let's see how we could use metaclasses -- what can we do
with metaclasses that we can't easily do without them?  Here's one
idea: a metaclass could automatically insert trace calls for all
method calls.  Let's first develop a simplified example, without
support for inheritance or other ``advanced'' Python features (we'll
add those later).

<PRE>
import types

class Tracing:
    def __init__(self, name, bases, namespace):
        """Create a new class."""
        self.__name__ = name
        self.__bases__ = bases
        self.__namespace__ = namespace
    def __call__(self):
        """Create a new instance."""
        return Instance(self)

class Instance:
    def __init__(self, klass):
        self.__klass__ = klass
    def __getattr__(self, name):
        try:
            value = self.__klass__.__namespace__[name]
        except KeyError:
            raise AttributeError, name
        if type(value) is not types.FunctionType:
            return value
        return BoundMethod(value, self)

class BoundMethod:
    def __init__(self, function, instance):
        self.function = function
        self.instance = instance
    def __call__(self, *args):
        print "calling", self.function, "for", self.instance, "with", args
        return apply(self.function, (self.instance,) + args)

Trace = Tracing('Trace', (), {})

class MyTracedClass(Trace):
    def method1(self, a):
        self.a = a
    def method2(self):
        return self.a

aninstance = MyTracedClass()

aninstance.method1(10)

print "the answer is %d" % aninstance.method2()
</PRE>

Confused already?  The intention is to read this from top down.  The
Tracing class is the metaclass we're defining.  Its structure is
really simple.

<P>

<UL>

<LI>The __init__ method is invoked when a new Tracing instance is
created, e.g. the definition of class MyTracedClass later in the
example.  It simply saves the class name, base classes and namespace
as instance variables.<P>

<LI>The __call__ method is invoked when a Tracing instance is called,
e.g. the creation of aninstance later in the example.  It returns an
instance of the class Instance, which is defined next.<P>

</UL>

<P>The class Instance is the class used for all instances of classes
built using the Tracing metaclass, e.g. aninstance.  It has two
methods:

<P>

<UL>

<LI>The __init__ method is invoked from the Tracing.__call__ method
above to initialize a new instance.  It saves the class reference as
an instance variable.  It uses a funny name because the user's
instance variables (e.g. self.a later in the example) live in the same
namespace.<P>

<LI>The __getattr__ method is invoked whenever the user code
references an attribute of the instance that is not an instance
variable (nor a class variable; but except for __init__ and
__getattr__ there are no class variables).  It will be called, for
example, when aninstance.method1 is referenced in the example, with
self set to aninstance and name set to the string "method1".<P>

</UL>

<P>The __getattr__ method looks the name up in the __namespace__
dictionary.  If it isn't found, it raises an AttributeError exception.
(In a more realistic example, it would first have to look through the
base classes as well.)  If it is found, there are two possibilities:
it's either a function or it isn't.  If it's not a function, it is
assumed to be a class variable, and its value is returned.  If it's a
function, we have to ``wrap'' it in instance of yet another helper
class, BoundMethod.

<P>The BoundMethod class is needed to implement a familiar feature:
when a method is defined, it has an initial argument, self, which is
automatically bound to the relevant instance when it is called.  For
example, aninstance.method1(10) is equivalent to method1(aninstance,
10).  In the example if this call, first a temporary BoundMethod
instance is created with the following constructor call: temp =
BoundMethod(method1, aninstance); then this instance is called as
temp(10).  After the call, the temporary instance is discarded.

<P>

<UL>

<LI>The __init__ method is invoked for the constructor call
BoundMethod(method1, aninstance).  It simply saves away its
arguments.<P>

<LI>The __call__ method is invoked when the bound method instance is
called, as in temp(10).  It needs to call method1(aninstance, 10).
However, even though self.function is now method1 and self.instance is
aninstance, it can't call self.function(self.instance, args) directly,
because it should work regardless of the number of arguments passed.
(For simplicity, support for keyword arguments has been omitted.)<P>

</UL>

<P>In order to be able to support arbitrary argument lists, the
__call__ method first constructs a new argument tuple.  Conveniently,
because of the notation *args in __call__'s own argument list, the
arguments to __call__ (except for self) are placed in the tuple args.
To construct the desired argument list, we concatenate a singleton
tuple containing the instance with the args tuple: (self.instance,) +
args.  (Note the trailing comma used to construct the singleton
tuple.)  In our example, the resulting argument tuple is (aninstance,
10).

<P>The intrinsic function apply() takes a function and an argument
tuple and calls the function for it.  In our example, we are calling
apply(method1, (aninstance, 10)) which is equivalent to calling
method(aninstance, 10).

<P>From here on, things should come together quite easily.  The output
of the example code is something like this:

<PRE>
calling &lt;function method1 at ae8d8&gt; for &lt;Instance instance at 95ab0&gt; with (10,)
calling &lt;function method2 at ae900&gt; for &lt;Instance instance at 95ab0&gt; with ()
the answer is 10
</PRE>

<P>That was about the shortest meaningful example that I could come up
with.  A real tracing metaclass (for example, <A
HREF="#Trace">Trace.py</A> discussed below) needs to be more
complicated in two dimensions.

<P>First, it needs to support more advanced Python features such as
class variables, inheritance, __init__ methods, and keyword arguments.

<P>Second, it needs to provide a more flexible way to handle the
actual tracing information; perhaps it should be possible to write
your own tracing function that gets called, perhaps it should be
possible to enable and disable tracing on a per-class or per-instance
basis, and perhaps a filter so that only interesting calls are traced;
it should also be able to trace the return value of the call (or the
exception it raised if an error occurs).  Even the Trace.py example
doesn't support all these features yet.

<P>

<HR>

<H1>Real-life Examples</H1>

<P>Have a look at some very preliminary examples that I coded up to
teach myself how to write metaclasses:

<DL>

<DT><A HREF="Enum.py">Enum.py</A>

<DD>This (ab)uses the class syntax as an elegant way to define
enumerated types.  The resulting classes are never instantiated --
rather, their class attributes are the enumerated values.  For
example:

<PRE>
class Color(Enum):
    red = 1
    green = 2
    blue = 3
print Color.red
</PRE>

will print the string ``Color.red'', while ``Color.red==1'' is true,
and ``Color.red + 1'' raise a TypeError exception.

<P>

<DT><A NAME=Trace></A><A HREF="Trace.py">Trace.py</A>

<DD>The resulting classes work much like standard
classes, but by setting a special class or instance attribute
__trace_output__ to point to a file, all calls to the class's methods
are traced.  It was a bit of a struggle to get this right.  This
should probably redone using the generic metaclass below.

<P>

<DT><A HREF="Meta.py">Meta.py</A>

<DD>A generic metaclass.  This is an attempt at finding out how much
standard class behavior can be mimicked by a metaclass.  The
preliminary answer appears to be that everything's fine as long as the
class (or its clients) don't look at the instance's __class__
attribute, nor at the class's __dict__ attribute.  The use of
__getattr__ internally makes the classic implementation of __getattr__
hooks tough; we provide a similar hook _getattr_ instead.
(__setattr__ and __delattr__ are not affected.)
(XXX Hm.  Could detect presence of __getattr__ and rename it.)

<P>

<DT><A HREF="Eiffel.py">Eiffel.py</A>

<DD>Uses the above generic metaclass to implement Eiffel style
pre-conditions and post-conditions.

<P>

<DT><A HREF="Synch.py">Synch.py</A>

<DD>Uses the above generic metaclass to implement synchronized
methods.

<P>

<DT><A HREF="Simple.py">Simple.py</A>

<DD>The example module used above.

<P>

</DL>

<P>A pattern seems to be emerging: almost all these uses of
metaclasses (except for Enum, which is probably more cute than useful)
mostly work by placing wrappers around method calls.  An obvious
problem with that is that it's not easy to combine the features of
different metaclasses, while this would actually be quite useful: for
example, I wouldn't mind getting a trace from the test run of the
Synch module, and it would be interesting to add preconditions to it
as well.  This needs more research.  Perhaps a metaclass could be
provided that allows stackable wrappers...

<P>

<HR>

<H2>Things You Could Do With Metaclasses</H2>

<P>There are lots of things you could do with metaclasses.  Most of
these can also be done with creative use of __getattr__, but
metaclasses make it easier to modify the attribute lookup behavior of
classes.  Here's a partial list.

<P>

<UL>

<LI>Enforce different inheritance semantics, e.g. automatically call
base class methods when a derived class overrides<P>

<LI>Implement class methods (e.g. if the first argument is not named
'self')<P>

<LI>Implement that each instance is initialized with <b>copies</b> of
all class variables<P>

<LI>Implement a different way to store instance variables (e.g. in a
list kept outside the instance but indexed by the instance's id())<P>

<LI>Automatically wrap or trap all or certain methods

<UL>

<LI>for tracing

<LI>for precondition and postcondition checking

<LI>for synchronized methods

<LI>for automatic value caching

</UL>
<P>

<LI>When an attribute is a parameterless function, call it on
reference (to mimic it being an instance variable); same on assignment<P>

<LI>Instrumentation: see how many times various attributes are used<P>

<LI>Different semantics for __setattr__ and __getattr__ (e.g.  disable
them when they are being used recursively)<P>

<LI>Abuse class syntax for other things<P>

<LI>Experiment with automatic type checking<P>

<LI>Delegation (or acquisition)<P>

<LI>Dynamic inheritance patterns<P>

``you can do that with __getattr__ hooks...'' :-)

	PKb1�Z�8����threads/Coroutine.pynu�[���# Coroutine implementation using Python threads.
#
# Combines ideas from Guido's Generator module, and from the coroutine
# features of Icon and Simula 67.
#
# To run a collection of functions as coroutines, you need to create
# a Coroutine object to control them:
#    co = Coroutine()
# and then 'create' a subsidiary object for each function in the
# collection:
#    cof1 = co.create(f1 [, arg1, arg2, ...]) # [] means optional,
#    cof2 = co.create(f2 [, arg1, arg2, ...]) #... not list
#    cof3 = co.create(f3 [, arg1, arg2, ...])
# etc.  The functions need not be distinct; 'create'ing the same
# function multiple times gives you independent instances of the
# function.
#
# To start the coroutines running, use co.tran on one of the create'd
# functions; e.g., co.tran(cof2).  The routine that first executes
# co.tran is called the "main coroutine".  It's special in several
# respects:  it existed before you created the Coroutine object; if any of
# the create'd coroutines exits (does a return, or suffers an unhandled
# exception), EarlyExit error is raised in the main coroutine; and the
# co.detach() method transfers control directly to the main coroutine
# (you can't use co.tran() for this because the main coroutine doesn't
# have a name ...).
#
# Coroutine objects support these methods:
#
# handle = .create(func [, arg1, arg2, ...])
#    Creates a coroutine for an invocation of func(arg1, arg2, ...),
#    and returns a handle ("name") for the coroutine so created.  The
#    handle can be used as the target in a subsequent .tran().
#
# .tran(target, data=None)
#    Transfer control to the create'd coroutine "target", optionally
#    passing it an arbitrary piece of data. To the coroutine A that does
#    the .tran, .tran acts like an ordinary function call:  another
#    coroutine B can .tran back to it later, and if it does A's .tran
#    returns the 'data' argument passed to B's tran.  E.g.,
#
#    in coroutine coA   in coroutine coC    in coroutine coB
#      x = co.tran(coC)   co.tran(coB)        co.tran(coA,12)
#      print x # 12
#
#    The data-passing feature is taken from Icon, and greatly cuts
#    the need to use global variables for inter-coroutine communication.
#
# .back( data=None )
#    The same as .tran(invoker, data=None), where 'invoker' is the
#    coroutine that most recently .tran'ed control to the coroutine
#    doing the .back.  This is akin to Icon's "&source".
#
# .detach( data=None )
#    The same as .tran(main, data=None), where 'main' is the
#    (unnameable!) coroutine that started it all.  'main' has all the
#    rights of any other coroutine:  upon receiving control, it can
#    .tran to an arbitrary coroutine of its choosing, go .back to
#    the .detach'er, or .kill the whole thing.
#
# .kill()
#    Destroy all the coroutines, and return control to the main
#    coroutine.  None of the create'ed coroutines can be resumed after a
#    .kill().  An EarlyExit exception does a .kill() automatically.  It's
#    a good idea to .kill() coroutines you're done with, since the
#    current implementation consumes a thread for each coroutine that
#    may be resumed.

#
# CONDITIONS
#
# A condition object is created via
#   import this_module
#   your_condition_object = this_module.condition(lock=None)
#
# As explained below, a condition object has a lock associated with it,
# used in the protocol to protect condition data.  You can specify a
# lock to use in the constructor, else the constructor will allocate
# an anonymous lock for you.  Specifying a lock explicitly can be useful
# when more than one condition keys off the same set of shared data.
#
# Methods:
#   .acquire()
#      acquire the lock associated with the condition
#   .release()
#      release the lock associated with the condition
#   .wait()
#      block the thread until such time as some other thread does a
#      .signal or .broadcast on the same condition, and release the
#      lock associated with the condition.  The lock associated with
#      the condition MUST be in the acquired state at the time
#      .wait is invoked.
#   .signal()
#      wake up exactly one thread (if any) that previously did a .wait
#      on the condition; that thread will awaken with the lock associated
#      with the condition in the acquired state.  If no threads are
#      .wait'ing, this is a nop.  If more than one thread is .wait'ing on
#      the condition, any of them may be awakened.
#   .broadcast()
#      wake up all threads (if any) that are .wait'ing on the condition;
#      the threads are woken up serially, each with the lock in the
#      acquired state, so should .release() as soon as possible.  If no
#      threads are .wait'ing, this is a nop.
#
#      Note that if a thread does a .wait *while* a signal/broadcast is
#      in progress, it's guaranteeed to block until a subsequent
#      signal/broadcast.
#
#      Secret feature:  `broadcast' actually takes an integer argument,
#      and will wake up exactly that many waiting threads (or the total
#      number waiting, if that's less).  Use of this is dubious, though,
#      and probably won't be supported if this form of condition is
#      reimplemented in C.
#
# DIFFERENCES FROM POSIX
#
# + A separate mutex is not needed to guard condition data.  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.  Then if some other thread is waiting to write, it's
#      allowed to proceed.  Else all threads (if any) waiting to read are
#      allowed to proceed.
#
#   .write_to_read()
#      Use instead of a .write_in to declare that the thread is done
#      writing but wants to continue reading without other writers
#      intervening.  If there are other threads waiting to write, they
#      are allowed to proceed only if the current thread calls
#      .read_out; threads waiting to read are only allowed to proceed
#      if there are no threads waiting to write.  (This is a
#      weakness of the interface!)

#
# How it works (assuming you've read the RFC):
#
# User commands are passed uninterpreted to the server.  However, the
# user never needs to send a PORT command.  Rather, the client opens a
# port right away and sends the appropriate PORT command to the server.
# When a response code 150 is received, this port is used to receive
# the data (which is written to stdout in this version), and when the
# data is exhausted, a new port is opened and a corresponding PORT
# command sent.  In order to avoid errors when reusing ports quickly
# (and because there is no s.getsockname() method in Python yet) we
# cycle through a number of ports in the 50000 range.
