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

首先阅读 shutil.copytree 和 shutil.copystat，以了解 stat 信息在哪里被复制。检查现有的 shutil 行为和测试，然后定义可配置的行为，以便在复制时根据要求保留或跳过 stat 信息。
