[3.6] bpo-24658: os.read() reuses _PY_READ_MAX (GH-10657)#10659
Merged
Conversation
os_read_impl() now also truncates the size to _PY_READ_MAX on macOS, to avoid to allocate a larger buffer even if _Py_read() is limited to _PY_READ_MAX bytes (ex: INT_MAX on macOS). (cherry picked from commit 9a0d7a7) Co-authored-by: Victor Stinner <vstinner@redhat.com>
