Threading support is still very new so stay conservative at this point and enable threading without the GIL. This requires users to protect concurrent access of mutatable Python objects (eg lists) with locks at the Python level (something you should probably do anyway). The advantage is that there is less of a performance hit for non-threaded code, because the VM does not need to constantly release/acquire the GIL. In the future the GIL will be made more efficient. There is also room to improve the efficiency of non-GIL code by not using mutex's if there is only one thread active.

# _FORTIFY_SOURCE is a feature in gcc/glibc which is intended to provide extra
|
|
# security for detecting buffer overflows. Some distros (Ubuntu at the very least)
|
|
# have it enabled by default.
|
|
#
|
|
# gcc already optimizes some printf calls to call puts and/or putchar. When
|
|
# _FORTIFY_SOURCE is enabled and compiling with -O1 or greater, then some
|
|
# printf calls will also be optimized to call __printf_chk (in glibc). Any
|
|
# printfs which get redirected to __printf_chk are then no longer synchronized
|
|
# with printfs that go through mp_printf.
|
|
#
|
|
# In MicroPython, we don't want to use the runtime library's printf but rather
|
|
# go through mp_printf, so that stdout is properly tied into streams, etc.
|
|
# This means that we either need to turn off _FORTIFY_SOURCE or provide our
|
|
# own implementation of __printf_chk. We've chosen to turn off _FORTIFY_SOURCE.
|
|
# It should also be noted that the use of printf in MicroPython is typically
|
|
# quite limited anyways (primarily for debug and some error reporting, etc
|
|
# in the unix version).
|
|
#
|
|

|
