I think non-determinism is more then os.urandom can deliver. As far as I
know the OS still does deterministic calculations, though they are maybe
less obvious. Maybe call it safer, OS dependent?

Maybe os.urandom is more random than the module random in the sense that
it is harder to figure out what comes next, but still deterministic. The
readings from the hardware are random and you usually don't know them, yet
what comes out

Maybe you could create a file without read permission (000) and try
to read from it.
I just checked. If I don't have read permissions, I am not able to open
the file. When I open a file and change permissions afterwards, I can read

The patch works, as this is what is implicitly happening anyway if you use
the function. There seem to be no tests for this function, so there is
nothing to break. I guess this is the right time to get some tests.
Gabriel, would you like
Jan Hosang jan.hos...@gmail.com added the comment:
Thanks Aduardo! (I could have sworn I tried that.) I changed the test to
reading from a file in 'wb' mode, which raised a EOFError before and now
raises IOErrors.

I changed the patch so it does not introduce new dependencies and fails
before the patch of isabstract().

12) I removed the try/except around the import. I have no clue if os
might be unavailable. Maybe leave out handling that until we see that
breaking.
I added the try/except because I saw that in other tests in the same
file when importing gc

I updated the checkout of the 26 branch, and the test runs fine now.
I have no clue about virtual time as well. If this is about passing time,
there should be better ways (than those which break if your computer gets
faster

I am not able to reproduce my own report :)
I'm sure I installed the 2.6.3 release, opened Terminal.app, checked
`which python` and ran `python -m test.regrtest -uall`. I remember that I
saw a crash report when I came back and some failed

While I was backporting the new buffer API to 2.7 I noticed some issues
in array_ass_slice() in Modules/arraymodule.c in the python 3k branch.
1) Manual memory reallocation had been replaced by calls to
array_resize. But I think when
Jan Hosang jan.hos...@gmail.com added the comment:
I think a timing out while loop explains much better what is happening. I
mean we are trying to keep the cpu busy for 0.9 seconds (if I understand
the definition of virtual time correctly) and not do 1 increments
(which might be done
Jan Hosang jan.hos...@gmail.com added the comment:
The mp_ass_subscript function looks fine in contrast to array_ass_slice().
So if array_ass_slice() is not accessible from the outside and is only
called with NULL as replacement parameter from the inside, I won't be able
to cause trouble
Jan Hosang jan.hos...@gmail.com added the comment:
Ezio, I moved the test to a separate method. Also I couldn't find
something to close the file if I don't care about errors. I thought an
assertRises would be wrong, as I am not debugging files here, so I added a
function to call a callable I

This is a 64 bit machine and the test failed for the checkout of the
python26-maint branch. I just configured and made it without any flags.
(Does that produce a 64 bit build?)

I attached a path for raising IOErrors in fromfile. I also added a
testcase which failed before.
The test opens a file and closes the file with os.close(fd) without
telling the file object, so fromfile doesn't notice it's reading from a
file

I tried to implement the new buffer API, but as soon as I add

I added a patch to replace back slashes by forward slashes in three
places, only one if them actually relevant to the errors in the attached

I kept the exception for mismatching filenames, but if you think it is
appropriate
