Don't check expanduser('~') if the home directory == the root directory
(ie, we are running as root).

defering to the encodings package.
As described in [ 763111 ] mbcs encoding should skip encodings package

Closes sf #761401.

Backport candidate.

sound while the first one is still running, as the first one
one might already have finished.

Fixes part of SF bug #763052.

Fixed a nit.

Also fix a memory leak.

- don't use "abc" in aString
- don't reorganize extension modules when not using zipimport

  installed Python, yet include any modules not in the std lib
- reworked extension module inclusion code: put all .so files in
  a subdirectory of Contents/Resources/, but more importantly,
  correctly support extensions that are submodules.

* Test with infinite inputs (using take() on the output)
* Test whether GC can find and eliminate cycles.

The obvious way for this assertion to fail is if the LineAndFileWrapper constructor is called when an empty line.  Raise a BadStatusError before the call.

after running the script so that a program could do something like:

os.environ['PYTHONINSPECT'] = 1

to programmatically enter a prompt at the end.

(After a patch by Skip Montanaro w/ proposal by Troy Melhase

Jeremy can check in the real things.

Analysis by Bob Halley:

  The test seems to expect that if time.daylight is true, then the
  is_dst field of the tm structure will be 1 too.  But this isn't
  the case, since daylight is true if the timezone does DST, *not*
  if DST is in effect.

* Added unittest that fails before, but not after Neil's fix to ceval.c.

Will backport.

I won't have time to write real docs, but spent a lot of time adding
comments to his code and fleshing out the exported functions' docstrings.
There's probably opportunity to consolidate how docstrings get extracted
too, and the new code for that is probably better than the old code for
that (which strained mightily to recover from 2.2's new class/type
gimmicks).

Minor improvement to previous bugfix.
Eating the remaining characters would lead to an endless loop
without a termination test.
