I noticed following code crashes. I'll post fix soon.
import mmap
import os
def main():
align = mmap.ALLOCATIONGRANULARITY
path = os.path.splitext(__file__)[0] + ".txt"
with open(path, "w") as f:
f.write("0" * align)
f.write("1" * align)
f.write("2" * align)
with open(path, "r+") as f:
m = mmap.mmap(f.fileno(), align)
m[align] # crash
m[align] = '1' # crash too
if __name__ == '__main__':
main()

This is obvious bug (and fix is obvious too), so I've commited in r69714. |
