STINNER Victor added the comment:

 New changeset 07fd54208434 by Victor Stinner in branch 'default':
 Issue #23708: Save/restore errno in _Py_read() and _Py_write()

When I wrote _Py_read()/_Py_write(), I added assertions on errno to ensure that 
errno is not modified. I chose to use assertions instead of save/restore errno 
because on Linux errno is not modified. Since they *are* platforms where errno 
is modified, it's safer to always save/restore errno.

_Py_read()/_Py_write() *must* set set errno because some callers uses it. It's 
more convinient to use errno than having to get the errno attribute of the 
raised OSError exception.

test_signal pass again on AMD64 Snow Leop 3.x buildbot, I close the issue.

[issue23708] PEP 475: Add _Py_read() and _Py_write() functions

2015-03-19 Thread STINNER Victor

STINNER Victor added the comment:

With py_read_write.patch in debug mode, test_threading crash with an assertion 
error because of the issue #15751. Currently, it's not possible to call 
assert(PyGILState_Check()); inside Py_NewInterpreter(), while creating a 
subinterpreter (ex: _testcapi.run_in_subinterp()).

The workaround is to comment the assertion in _Py_read() and Py_write() until 
the issue #15751 is fixed.

[issue23708] PEP 475: Add _Py_read() and _Py_write() functions

2015-03-19 Thread STINNER Victor

New submission from STINNER Victor:

To factorize code handling EINTR, I propose add 2 new functions to fileutils.h: 
_Py_read() and _Py_write().

Attached patch adds these functions and use them in the os and _io modules.

The code of the functions is based on the code from the os and _io modules. The 
main change is that the functions now truncate code if greater than 
PY_SSIZE_T_MAX. Other changes are just refactoring.
