Compile cache frequently stale #17

Open cshenton-work opened 4 months ago

cshenton-work commented 4 months ago

Windows 11 Python 3.12.2 with installer Slangpy 1.1.22

I am running into an issue where slang's cache is frequently pulling in stale code, for example throwing up warnings for code I deleted since the last run.

It could be that the mechanism used to detect changes to the .slang source files is faulty?

Hi @cshenton-work, would you be able to provide a code snippet that shows this issue? Is the stale cache caused by changing the main .slang file or an imported file? (or a .cu file that you may be using for interop)

One way to see what's going on is to use the verbose form loadModule('myfile.slang', verbose=True). You should see a wall of text showing the reasons for skipping the re-build. Pasting that here would definitely help me zero in on the issue. Thanks in advance!

I've noticed that the cache will go stale if you rename the folder containing the slang code. Maybe this is specific to when the directory is nested once.
