Renaming multiple files causes lockdown
Posted: Wed Oct 21, 2015 8:02 amHi,
I have tried to rename multiple files in my project, but the system always halts after third renaming.
To give you a better understanding of the problem, let me give you guys a couple of examples how I started narrowing down this thing.
To start with I have files read.txt, write.txt, foo.txt, bar.txt, file.txt uploaded to the ESP with ESPlorer.
I use script "print_all_files.lua" to get a listing of the files and print them out for me.
Attempt 1:
Attemp 2:
Attemp 3:
The third attempt implies that those files would stay somehow open and block the use of another files. Or maybe there is some buffer that is filling up with data associated to the new files, and when the file is removed, so is the associated data.
I have tried it so that after every time I have renamed a file, I have opened it, checked it and if it's ok I have closed it. But this also fails after the third renaming. In this case I cannot open the third file to verify that the renaming was successful.
Is there something I am missing here?
