with major C compilers (VACPP, EMX+gcc and [Open]Watcom).
Also tidy up the export of spawn*() symbols in the os module to match what
is found/implemented.
(Championed by Bob Ippolito.)
The update() method for mappings now accepts all the same argument forms
as the dict() constructor. This includes item lists and/or keyword
arguments.
The new execvpe code would sometimes do the wrong thing when a
non-executable file existed earlier in the path and an executable file
of the same name existed later in the path. This patch restores the
proper behavior (which is to execute the second file). When only a
non-executable file exists, the correct error is still reported.
1) Do not attempt to exec a file which does not exist
just to find out what error the operating system
returns. This is an exploitable race on all platforms
that support symbolic links.
2) Immediately re-raise the exception if we get an
error other than errno.ENOENT or errno.ENOTDIR. This
may need to be adapted for other platforms.
(As a security issue, this should be considered for 2.1
and 2.2 as well as 2.3.)
This adds unsetenv to posix, and uses it in the __delitem__ method of
os.environ.
(XXX Should we change the preferred name for putenv to setenv, for
consistency?)
UNIX style fork/execve/wait are not fully compatible with thread
support on BeOS. For Python, that means neither fork() from import
nor import from a fork work reliably. os._execvpe() does the latter,
importing tempfile to set up a tantalizing target for hackers. This
patch replaces both the tempfile name generation and the exec that
uses it, in case we're on BeOS. Need this for
setup:distutils:execvp(); symptoms are random crashes and internal
BeOS error messages about th name, in case we're on BeOS. It's an
issue because setup.py + distutils calls os.execvp(); symptoms are
random crashes during setup.py, and internal BeOS error messages
about thread IDs.
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
I think that after this patch, all objects in the os module (with names
that don't start with "_") that can have docstrings, do, on Linux at
least.
Also fix a nit in one of my spawn* docstrings.
