Make it configurable whether shutil.copytree copies stat() information

Feature or enhancement

Proposal:

When copying a tree of files, it is sometimes useful for them to have default stat() information (file permissions, mtime and so on), instead of it being copied from the source files, for example when copying files from a read-only location to a temporary location where they may be modified or deleted later, but shutil.copytree unconditionally copies stat() information.

In a script that I wrote, I worked around the lack of this feature by monkey-patching the shutil.copystat function to do nothing, but this is clearly not a robust approach.

Ideally I would like to be able to turn off the stat() copying behavior by passing a named argument to copytree, such as:

shutil.copytree(src, dst, copystat=False)

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

No response

Start by reading shutil.copytree and shutil.copystat to understand where stat information is copied. Check the existing shutil behavior and tests, then define the configurable behavior so copying can preserve or skip stat information as requested.
