1. Remove "idle" script, it lives in Tools/scripts/ now.
2. Remove shebang from idle.py, should be called explicitly.
3. Remove obsolete test code from rpc.py; needs unit test.
file_truncate(): C doesn't define what fflush(fp) does if fp is open
for update, and the preceding I/O operation on fp was input. On Windows,
fflush() actually changes the current file position then. Because
Windows doesn't support ftruncate() directly, this not only caused
Python's file.truncate() to change the file position (contra our docs),
it also caused the file not to change size.
Repaired by getting the initial file position at the start, restoring
it at the end, and tossing all the complicated micro-efficiency checks
trying to avoid "provably unnecessary" seeks. file.truncate() can't
be a frequent operation, and seeking to the current file position has
got to be cheap anyway.
Bugfix candidate.
random.sample() uses one of two algorithms depending on the ratio of the
sample size to the population size. One of the algorithms accepted any
iterable population argument so long as it defined __len__(). The other
had a stronger requirement that the population argument be indexable.
While it met the documentation specifications which insisted that the
population argument be a sequence, it made random.sample() less usable
with sets. So, the second algorithm was modified to coerce non-indexable
iterables and dictionaries into a tuple before proceeding.
quotes. Fixes SF bug #794466, with the essential patch provided by
Stuart D. Gathman. Specifically,
_parseparam(), _get_params_preserve(): Use the parsing function that
takes quotes into account, as given (essentially) in the bug report's
test program.
Backport candidate.
For smaller datasets, it is not always true the increasing the compression
level always results in better compression. Removed the test which made
this invalid assumption.

* Convert three test modules to unittest format.
* Expanded coverage in test_structseq.py.
* Raymond added a new test in test_sets.py
When the indents were set to longer than the width and long word breaking
was enabled, an infinite loop would result because the inner loop did not
assure that at least one character was stripped off on every pass.
platforms (e.g., Cygwin) that are "particular" about open files, this will
cause other regression tests that use the same temp file to fail:
$ ./python.exe -E -tt Lib/test/regrtest.py -l
test_largefile test_mmap test_mutants
test_largefile
test test_largefile failed -- got -1794967295L, but expected 2500000001L
test_mmap
test test_mmap crashed -- exceptions.IOError: [Errno 13] Permission denied: '@test'
test_mutants
test test_mutants crashed -- exceptions.IOError: [Errno 13] Permission denied: '@test'
This patch solves the problem by adding missing "try/finally" blocks. Note
that the "large" size of this patch is due to many white space changes --
otherwise, the patch is small.
I tested this patch under Red Hat Linux 8.0 too.

* Relaxed the argument restrictions for non-operator methods. They now
allow any iterable instead of requiring a set. This makes the module
a little easier to use and paves the way for an efficient C
implementation which can take better advantage of iterable arguments
while screening out immutables.
* Deprecated Set.update() because it now duplicates Set.union_update()
* Adapted the tests and docs to include the above changes.
* Added more test coverage including testing identities and checking
to make sure non-restartable generators work as arguments.
Will backport to Py2.3.1 so that the interface remains consistent
across versions. The deprecation of update() will be changed to
a FutureWarning.

The default seed is time.time().
Multiplied by 256 before truncating so that fractional seconds are used.
This way, two successive calls to random.seed() are much more likely
to produce different sequences.
Also remove now unnecessary property attributes for thread safety
(no longer have lazy attributes) and code simplicity reasons.
Timezone storage has been reworked to be simpler and more flexible. All values
in LocaleTime instances are lower-cased. This is all done to simplify the
module.
The module now assumes nothing beyond the strptime function will be exposed for
general use beyond providing functionality for strptime.
caught when executing test_strptime, test_logging, and test_time in that order
when the testing of "%c" occured. Suspect the cache was not being recreated
(the test passed when test_logging was forced to re-establish the locale).
Obtain the original locale in the documented way. This way actually
works for me.
Restore the original locale at the end, instead of forcing to "C".
Move the locale fiddling into the test driver instead of doing it as a
side effect of merely importing the module. I don't know why the test
is mucking with locale (and also added a comment saying so), but it
surely has no justification for doing that as an import side-effect.
Now whenever the locale-changing code executes, the locale-restoring code
will also get run.

are satisfied in a case-insensitive manner, the attempt to import (the
non-existent) fcntl gets satisfied by FCNTL.py instead, and the tempfile
module defines a Unix-specific _set_cloexec() function in that case. As
a result, temp files can't be created then (blows up with an AttributeError
trying to reference fcntl.fcntl). This just popped up in the spambayes
project, where there is no apparent workaround (which is why I'm pushing
this in now).
If this doesn't happen, it leaves the locale in a state that can cause
other tests to fail. For example, running test_strptime,
test_logging, and test_time in that order.
