Subject: [Cocci] Can I pass a variable from a Python script in one rule to another rule in the same .cocci file?
Date: Fri, 4 Jan 2019 15:57:25 -0600 [thread overview]
Message-ID: <CAOZdJXWUhEcm8HgJFE2L1dqgMRX51X+LF=b=Obzj55pU4gc3QA@mail.gmail.com> (raw)
In one rule, I have some Python code that parses a string literal to
see what it looks like. If I detect a specific pattern, then I want
another rule (that has no Python code) to act differently.
More specifically, if a string literal passed as a parameter to
DBG_PRINTF() starts with "NVRM: ", then I want my script to replace
DBG_PRINTF with NV_PRINTF. This works today.
If the string does not begin with "NVRM:", however, then I want
DBG_PRINTF changed to NV_PRINTF_EX instead.
If this can't work, an alternative would be to create a second script
that handles DBG_PRINTF to NV_PRINTF_EX. However, it would need to
abort the change if the Python script detects that NVRM: doesn't
exist. So is there a way for Python to return a value that says,
"Woah, stop and undo everything you just did!"
