Issue 12083: Compile-time option to avoid writing files, including generated bytecode (original) (raw)

PEP 304 provides a runtime option to avoid saving generating bytecode files. However, for embedded usage, it would help to have a compile-time option to remove all the file-writing code entirely, hardcoding PYTHONBYTECODEBASE="". I ran into this when porting Python to an embedded platform, which will never support any form of filesystem write operations; currently, I have to provide dummy functions for writing files, which error out when attempting to write to anything other than stdout or stderr.
