[New-bugs-announce] [issue20396] Argument Clinic: Touch source file if any output file changed

[Larry Hastings]

New submission from Larry Hastings:

A minor bug, but still one that could cause confusion.  It's already bitten me once.

If I change the code generator in clinic.py, then --make everything, files using the "file" destination often won't change.  All the changes to the generated code will go in the generated file.  And since the UNIX build process ignores those generated files, it doesn't rebuild the source file.  I'd have to use "--make -f".

This won't just happen to me though.  If you update your trunk and run "make clinic" this could easily happen to you too.

I propose that Clinic handle this as follows: if the generated file changes, but the source file does not, it "touches" the source file.  (Technically I'll probably just rewrite the source file, as I already have code that does that.)
