I can't reproduce the problem here. And I still can't figure out why it
would need to recompile the PSP file unless the PSP file changed on disk.
The key chunk of code in PSPServletFactory.py is lines 162-165:
if self._cacheClassFiles and os.path.exists(cachedfilename)
and os.stat(cachedfilename)[6] > 0:
if os.path.getmtime(cachedfilename) > mtime:
instance =
self.createInstanceFromFile(trans,cachedfilename,classname,mtime,0)
return instance
Which is basically saying, "if we're supposed to cache class files, the
cached class file exists and has non-zero size, and the cached class file is
newer than the original PSP file, then create a Servlet instance from the
cached class file".
This should always happen after the PSP is initially compiled.
So I would recommend instrumenting this code (with print statements) to find
out why these two if statements aren't always succeeding.
