@blarsen, OK, but if you want to pursue this, please open a new issue against
the current versions. This issue was closed years ago and against earlier
versions so your comments will not get acted on.

@eryksun, you are right! The output *is* an absolute path as far as
`os.path.isabs` is concerned.
@ned.deily, you are right about my example --- I transcribed it wrong, and it
should be `-c`.
The system in question is not a Mac OS system, but a Linux system
Ned Deily added the comment:
@blarsen, and there's something strange about your example. '-m' won't work
with a real python executable, presumably you meant '-c'. And judging from the
paths involved, I'm guessing you are using MacPorts on OS X. With either
MacPorts or any other OS X
Eryk Sun added the comment:
"/opt/local/bin/../bin/python2.7" is an absolute path.
>>> os.path.isabs('/opt/local/bin/../bin/python2.7')
True
It's not relative to the working directory.

It looks like sys.executable is *not* always an absolute path. In Python 2.7:
$ which python2.7
/opt/local/bin/python2.7
$ cd /opt/local/bin
$ ../bin/python2.7 -m 'import sys; print(sys.executable)'
/opt/local/bin/../bin/python2.7

Attaching an updated patch. The documentation now says that sys.executable may
be an empty string. The patch also adds a test to make sure that sys.executable

In CPython, embedding doesn't change the behavior.

LGTM too.
You could also add a test to test_sys ensuring that sys.executable is always
executable.

And that sys.executable is absolute?
sys.executable is an empty string if sys.argv[0] has been changed and Python is
unable to retrieve the

Well, its value is computed by a function named

New submission from Éric Araujo mer...@netwok.org:
I wanted to know if sys.executable was always an absolute path but the doc does
not talk about that.
(My use case is that I’d like to reload a process and I wonder if I can call
os.execve or if I need to use os.execvpe.)
