New submission from Andrew Svetlov <andrew.svet...@gmail.com>:
On Linux maximum data size for sendfile call is 0x7ffff000: sendfile() will transfer at most 0x7ffff000 (2,147,479,552) bytes, returning the number of bytes actually transferred. (This is true on both 32-bit and 64-bit systems.) Limiting max block size to this value on all OSes makes sense: splitting transferring the very huge file into several syscalls doesn't hurt performance anyway. Windows uses DWORD for size in TransmitFile, so the size is limited as well. ---------- components: macOS messages: 329366 nosy: asvetlov, ned.deily, ronaldoussoren priority: normal severity: normal status: open title: Limit max sendfile chunk to 0x7ffff000 versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35179> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
