os.path.getsize and zipfile.write lack built-in recursive directory support

[iuyp387]

Feature or enhancement

Proposal:

The os.path.getsize and zipfile.write functions should support recursive directory searching. While it's possible to implement this with custom code, it's somewhat cumbersome.

Has this already been discussed elsewhere?

Please open a https://discuss.python.org/c/ideas/6 thread to see if this is necessary for the stdlib.

For zipfile, this can be achieved using shutil instead in general but a writedir() would be perhaps an idea.

For getsize, as every directory on Linux can be regarded as a file, getsize() shouldn't be changed. We should have an other function as well and we should rely on scandir() to get the DirEntry information. Unfortunately by the time we get the information, an entry might be gone so should we raise OSError while we are walking through the directory or not? (getsize does raise such exception). As such, a prior discussion must be done.
